Mediterranean cuisine dishes include salted cured fish roe.
[ { "docid": "Mediterranean_cuisine", "text": "Mediterranean cuisine represents the foods and methods of preparation by people of the Mediterranean Basin region , primarily as it pertains to Southern Europe . The region 's food came to be seen as a more or less unified cuisine following the cookery writer Elizabeth David 's book , A Book of Mediterranean Food ( 1950 ) . Other writers , such as the Tunisian historian Mohamed Yassine Essid , have agreed with David , defining the three core elements of the cuisine as the olive , wheat , and the grape , yielding olive oil , bread and pasta , and wine , respectively . The geographical area covered broadly follows the distribution of the olive tree , as noted by David and Essid . The region spans a wide variety of cultures with distinct cuisines , in particular ( going anticlockwise around the region ) the Maghrebi , Levantine , Ottoman ( Turkish ) , Greek , Italian , Provençal ( French ) , and Spanish . However , the historical connections of the region , as well as the impact of the Mediterranean Sea on the region 's climate and economy , mean that these cuisines share dishes beyond the core trio of oil , bread , and wine , such as roast lamb or mutton , meat stews with vegetables and tomato ( for example , Spanish andrajos and Italian ciambotta ) , and the salted cured fish roe , bottarga , found across the region . The cooking of the area is not to be confused with the Mediterranean diet , made popular because of the apparent health benefits of a diet rich in olive oil , wheat and other grains , fruits , vegetables , and a certain amount of seafood , but low in meat and dairy products . Mediterranean cuisine encompasses the ways that these and other ingredients , including meat , are dealt with in the kitchen , whether they are health-giving or not .", "title": "" } ]

phosphate additives
[ { "docid": "MED-3096", "text": "Background and objectives: Uncooked meat and poultry products are commonly enhanced by food processors using phosphate salts. The addition of potassium and phosphorus to these foods has been recognized but not quantified.

Results: Products that reported the use of additives had an average phosphate-protein ratio 28% higher than additive free products; the content ranged up to almost 100% higher. Potassium content in foods with additives varied widely; additive free products all contained <387 mg/100 g, whereas five of the 25 products with additives contained at least 692 mg/100 g (maximum 930 mg/100 g).

MEASUREMENTS: Phosphorus by using Association of Analytical Communities official method 984.27; protein by using Association of Analytical Communities official method 990.03. RESULTS: We found that the ratio of phosphorus to protein content in these items ranged from 6.1 to 21.5 mg of phosphorus per 1 g of protein. The mean ratio in the 19 food products with a label listing phosphorus as an additive was 14.6 mg/g compared with 9.0 mg/g in the 11 items without listed phosphorus. The phosphorus content of only 1 precooked food product was available in a widely used dietary database. LIMITATIONS: Results cannot be extrapolated to other products. Manufacturers also may alter the phosphorus content of foods at any time. Protein content was not directly measured for all foods.

The results were compared with provisional acceptable permissible limits (PAPLs). The maximum estimated dietary intake (MEDI) of Al for the examined samples was calculated. In addition, an experimental study was conducted to determine the possible leaching of Al from cookware in milk during boiling. The obtained results showed that Al concentration in examined bulk farm milk samples was found to be negligible. In contrast, market milk revealed higher concentration, 65.0% of the examined samples were above the PAPLs. The results revealed significant difference of Al concentration among them. The Al levels in processed cheese wrapped in Al foil were significantly higher than those found in samples packed in glass containers with a significant difference of Al concentration between them. Also, 20% of the examined milk powder samples exceeded the PAPLs (0.01 to 0.4 mg/kg). The MEDI for Al in bulk farm milk, control market milk, market milk boiled in Al cookware, market milk boiled in stainless-steel cookware, processed cheese wrapped in Al foil, processed cheese packed in glass containers, and milk powder were calculated as 3.0%, 61.0%, 63.0%, 61.0%, 428.0%, 220.0%, and 166.0% from \"PTDI,\" respectively. The results of the experimental study showed no marked significant differences of Al concentration between market milk (control group) and those boiled in Al cookware, as well as to those boiled in stainless-steel cookware.

Therefore, all milk cans should be constructed of stainless steel, prevent the entrance of tap water into milk, and the processed cheese should be packed in glass containers and not wrapped in Al foil.

Design The labels of 2394 best selling branded grocery products in northeast Ohio were reviewed for phosphorus additives. The top 5 best selling products containing phosphorus additives from each food category were matched with similar products without phosphorus additives and analyzed for phosphorus content. Four days of sample meals consisting of foods with and without phosphorus additives were created and daily phosphorus and pricing differentials were computed. Setting Northeast Ohio Main outcome measures Presence of phosphorus-containing food additives, phosphorus content Results 44% of the best selling grocery items contained phosphorus additives. The additives were particularly common in prepared frozen foods (72%), dry food mixes (70%), packaged meat (65%), bread & baked goods (57%), soup (54%), and yogurt (51%) categories. Phosphorus additive containing foods averaged 67 mg phosphorus/100 gm more than matched non-additive containing foods (p=.03). Sample meals comprised mostly of phosphorus additive-containing foods had 736 mg more phosphorus per day compared to meals consisting of only additive-free foods. Phosphorus additive-free meals cost an average of $2.00 more per day. Conclusion Phosphorus additives are common in best selling processed groceries and contribute significantly to their phosphorus content.

We used ESHA Food Processor SQL Software to determine the expected phosphorus content of each product. Results Of 38 chicken products, 35 (92%) had phosphorus containing additives listed among their ingredients. For every category of chicken products containing additives, the actual phosphorus content was greater than the content expected from nutrient database. For example, actual phosphorus content exceeded expected phosphorus content by an average of 84 mg/100g for breaded breast strips. There was also a great deal of variation within each category. For example, the difference between actual and expected phosphorus content ranged from 59 to 165 mg/100g for breast patties.

[ { "docid": "MED-3092", "text": "BACKGROUND: Restriction of dietary phosphorus is a major aspect of patient care in those with renal disease. Restriction of dietary phosphorus is necessary to control for phosphate balance during both conservative therapy and dialysis treatment. The extra amount of phosphorus which is consumed as a result of phosphate-containing food additives is a real challenge for patients with renal disease and for dieticians because it represents a \"hidden\" phosphate load. The objective of this study was to measure phosphorus content in foods, common protein sources in particular, and comprised both those which included a listing of phosphate additives and those which did not. METHODS: Determinations of dry matter, nitrogen, total and soluble phosphate ions were carried out in 60 samples of foods, namely cooked ham, roast breast turkey, and roast breast chicken, of which, 30 were with declared phosphate additives and the other 30 similar items were without additives. RESULTS: Total phosphorus (290 ± 40 mg/100 g vs. 185 ± 23 mg/100 g, P < .001) and soluble phosphorus (164 ± 25 mg/100 g vs. 100 ± 19 mg/100 g, P < .001) content were higher in products containing additives than in foods without additives. No difference was detected between the 2 groups regarding dry matter (27.2 ± 2.0 g/100 g vs. 26.7 ± 1.9 g/100 g) or total nitrogen (3.15 ± 0.40 g/100 g vs. 3.19 ± 0.40 g/100 g). Consequently, phosphorus intake per gram of protein was much greater in the foods containing phosphorus additives (15.0 ± 3.1 mg/g vs. 9.3 ± 0.7 mg/g, P < .001). CONCLUSIONS: Our results show that those foods which contain phosphate additives have a phosphorus content nearly 70% higher than the samples which did not contain additives. This creates a special concern because this extra amount of phosphorus is almost completely absorbed by the intestinal tract. These hidden phosphates worsen phosphate balance control and increase the need for phosphate binders and related costs. Information and educational programs are essential to make patients with renal disease aware of the existence of foods with phosphate additives. Moreover, these facts highlight the need for national and international authorities to devote more attention to food labels which should clearly report the amount of natural or added phosphorus.

For example, a study of patients in stage CKD 5 (with an annual mortality of about 20%) revealed that 12% of all deaths in this group were attributable to an elevated serum phosphate concentration. Recently, a high-normal serum phosphate concentration has also been found to be an independent predictor of cardiovascular events and mortality in the general population. Therefore, phosphate additives in food are a matter of concern, and their potential impact on health may well have been underappreciated. Methods We reviewed pertinent literature retrieved by a selective search of the PubMed and EU databases (www.zusatzstoffe-online.de, www.codexalimentarius.de), with the search terms “phosphate additives” and “hyperphosphatemia.” Results There is no need to lower the content of natural phosphate, i.e. organic esters, in food, because this type of phosphate is incompletely absorbed; restricting its intake might even lead to protein malnutrition. On the other hand, inorganic phosphate in food additives is effectively absorbed and can measurably elevate the serum phosphate concentration in patients with advanced CKD. Foods with added phosphate tend to be eaten by persons at the lower end of the socioeconomic scale, who consume more processed and “fast” food. The main pathophysiological effect of phosphate is vascular damage, e.g. endothelial dysfunction and vascular calcification. Aside from the quality of phosphate in the diet (which also requires attention), the quantity of phosphate consumed by patients with advanced renal failure should not exceed 1000 mg per day, according to the guidelines.

It is of unknown aetiology, but evidence suggests that it results from a combination of genetic predisposition and environmental factors. Bacterial-sized microparticles (0.1-1.0 microm) are potent adjuvants in model antigen-mediated immune responses and are increasingly associated with disease. Microparticles of TiO2 and aluminosilicate accumulate in macrophages of human gut-associated lymphoid tissue where the earliest signs of lesions in Crohn's disease are observed. Dietary microparticles are of endogenous or exogenous origin. Endogenous microparticles dominate and are calcium phosphate (most probably hydroxyapatite), which precipitates in the lumen of the mid-distal gastrointestinal tract due to secretion of Ca and phosphate in the succus entericus. Exogenous dietary microparticles are contaminants (soil and/or dust) and food additives. TiO2, for example, is a food colourant, and aluminosilicates are anti-caking agents, although some aluminosilicates occur as natural contaminants.

METHODS: TP and DP content of 21 foods and drinks of plant origin were measured by inductively coupled plasma optical emission spectrometry. In DP analysis, samples were digested enzymatically in principle in the same way as in the alimentary canal before P analyses. The most popular national brands were chosen for analysis. RESULTS: The highest amount of TP (667 mg/100 g) was found in sesame seeds with hull, which also had the lowest percentage of DP (6%) to TP. Instead, in cola drinks and beer, the percentage of DP to TP was 87 to 100% (13 to 22 mg/100 g).

Once ingested, exogenous microparticles are unlikely to pass through the gastrointestinal tract without adsorbing to their surfaces some ions and molecules of the intestinal lumen.

This provides the rationale for recommendations to restrict dietary phosphate intake to 800 mg/d. However, the protein source of the phosphate may also be important. Design, setting, participants, & measurements We conducted a crossover trial in nine patients with a mean estimated GFR of 32 ml/min to directly compare vegetarian and meat diets with equivalent nutrients prepared by clinical research staff. During the last 24 hours of each 7-day diet period, subjects were hospitalized in a research center and urine and blood were frequently monitored. Results The results indicated that 1 week of a vegetarian diet led to lower serum phosphorus levels and decreased FGF23 levels. The inpatient stay demonstrated similar diurnal variation for blood phosphorus, calcium, PTH, and urine fractional excretion of phosphorus but significant differences between the vegetarian and meat diets. Finally, the 24-hour fractional excretion of phosphorus was highly correlated to a 2-hour fasting urine collection for the vegetarian diet but not the meat diet.

The antinutritional effects of phytic acid primarily relate to the strong chelating associated with its six reactive phosphate groups. Its ability to complex with proteins and particularly with minerals has been a subject of investigation from chemical and nutritional viewpoints. The hydrolysis of phytate into inositol and phosphates or phosphoric acid occurs as a result of phytase or nonenzymatic cleavage. Enzymes capable of hydrolysing phytates are widely distributed in micro-organisms, plants and animals. Phytases act in a stepwise manner to catalyse the hydrolysis of phytic acid. To reduce or eliminate the chelating ability of phytate, dephosphorylation of hexa- and penta-phosphate forms is essential since a high degree of phosphorylation is necessary to bind minerals. There are several methods of decreasing the inhibitory effect of phytic acid on mineral absorption (cooking, germination, fermentation, soaking, autolysis).

Indeed, calciuria is directly related to net acid excretion. Different food proteins differ greatly in their potential acid load, and therefore in their acidogenic effect. A diet high in acid-ash proteins causes excessive calcium loss because of its acidogenic content. The addition of exogenous buffers, as chemical salts or as fruits and vegetables, to a high protein diet results in a less acid urine, a reduction in net acid excretion, reduced ammonium and titratable acid excretion, and decreased calciuria. Bone resorption may be halted, and bone accretion may actually occur. Alkali buffers, whether chemical salts or dietary fruits and vegetables high in potassium, reverse acid-induced obligatory urinary calcium loss.

Although there might be various different triggering events in the early stages of the disease, they seem to converge on a few characteristic final pathways in the late stages, characterized by inflammation and neurodegeneration. In this review, we put forward the hypothesis that advanced glycation end products (AGEs) and their precursors, including methylglyoxal, are both biomarkers and causative agents (\"gerontotoxins\") characteristic for this disorder. Accumulation of AGEs is a normal feature of aging, but is accelerated in AD, where AGEs can be detected in amyloid plaques and neurofibrillary tangles. AGE modification may explain many of the neuropathological and biochemical features of AD such as extensive protein cross-linking, inflammation, oxidative stress and neuronal cell death. We suggest that methylglyoxal is one of the major carbonyl species responsible for the formation of AGEs. We propose that one promising pharmacological approach to prevent the formation of AGEs would be to lower the methylglyoxal concentration. This can be achieved, for example, by decreasing the concentration of methylglyoxal precursors such as d-glyceraldehyde-3-phosphate by allowing a higher flux through the pentose phosphate pathway or by increasing methylglyoxal detoxification through the glyoxalase system. Alternatively, methylglyoxal could be scavenged by various types of carbonyl scavengers. Copyright © 2010 Elsevier Inc.

Converging evidence from in vitro, clinical and epidemiological studies suggest that increased P is associated with vascular calcification and mortality. When vessels are exposed to high P conditions in vitro, they develop apoptosis, convert to bone-like cells and develop extensive calcification. Clinical studies in children on dialysis show that high P is associated with increased vessel wall thickness, arterial stiffness and coronary calcification. Epidemiological studies in adult dialysis patients demonstrate a significant and independent association between raised P and mortality. Importantly, raised P is associated with cardiovascular changes even in pre-dialysis CKD, and also in subjects with normal renal function but high P. All P binders can effectively reduce serum P, and this decrease is linked to improved survival. Raised serum P triggers the release of fibroblast growth factor 23 (FGF-23), which has the beneficial effect of increasing P excretion in early CKD, but is increased several 1,000-fold in dialysis, and may be an independent cardiovascular risk factor. Both FGF-23 and its co-receptor Klotho may have direct effects on the vasculature leading to calcification.

Both purified bacterium-derived recombinant CMV IL-10 and CMV IL-10 expressed in supernatants of human cells were found to inhibit proliferation of mitogen-stimulated peripheral blood mononuclear cells (PBMCs), with specific activity comparable to that of recombinant human IL-10. In addition, CMV IL-10 expressed from human cells inhibited cytokine synthesis, as treatment of stimulated PBMCs and monocytes with CMV IL-10 led to a marked decrease in production of proinflammatory cytokines. Finally, CMV IL-10 was observed to decrease cell surface expression of both major histocompatibility complex (MHC) class I and class II molecules, while conversely increasing expression of the nonclassical MHC allele HLA-G. These results demonstrate for the first time that CMV has a biologically active IL-10 homolog that may contribute to immune evasion during virus infection.", "title": "Potent immunosuppressive activities of cytomegalovirus-encoded interleukin-10." }, { "docid": "39637840", "text": "BLM, WRN, and p53 are involved in the homologous DNA recombination pathway.

Here we define break-induced telomere synthesis and demonstrate that it utilizes a specialized replisome, which underlies ALT telomere maintenance. DNA double-strand breaks enact nascent telomere synthesis by long-tract unidirectional replication. Proliferating cell nuclear antigen (PCNA) loading by replication factor C (RFC) acts as the initial sensor of telomere damage to establish predominance of DNA polymerase δ (Pol δ) through its POLD3 subunit. Break-induced telomere synthesis requires the RFC–PCNA–Pol δ axis, but is independent of other canonical replisome components, ATM and ATR, or the homologous recombination protein Rad51.

Instead, its absence inhibits the recruitment of the MRE11 nuclease to stalled replication forks, which in turn protects nascent DNA strands from extensive degradation. More generally, acquisition of PARP inhibitors and cisplatin resistance is associated with replication fork protection in Brca2-deficient tumour cells that do not develop Brca2 reversion mutations.

The last decades have shown that how the Swiss Franc valuation is less and less correlated with the performance of the Swiss economy. The Swiss franc is used as a safe haven when the global economy goes bad or is uncertain. In those times, the Swiss franc can be overevaluated, at least as compared to the purchasing power. When the global economy is improving, the over-appreciation of the Swiss franc tends to disapear ; this is happening now (in Mid-2017). As a summary, the Swiss franc itself is not truly correlated with the competitiveness of the Swiss economy, but more about how people in the world are anxious.

Becoming a US tax resident is a very serious decision, that has significant consequences for any non-American with >$0 in assets. When it involves cross-border business interests, it becomes even more significant. Especially if Switzerland is involved. The US has driven at least one iconic Swiss financial institution out of business for sheltering US tax residents from the IRS/FinCEN. So in a nutshell, you need to learn and be afraid of the following abbreviations: and many more. The best thing for you would be to find a good US tax adviser (there are several large US tax firms in the UK handling the US expats there, go to one of those) and get a proper assessment of all your risks and get a proper advice. You can get burnt really hard if you don't prepare and plan properly. Now here's that bottom line. Q) Will I have to submit the accounts for the Swiss Business even though Im not on the payroll - and the business makes hardly any profit each year. I can of course get our accounts each year - BUT - they will be in Swiss German! That's actually not a trivial question. Depending on the ownership structure and your legal status within the company, all the company's bank accounts may be reportable on FBAR (see link above). You may also be required to file form 5471. Q) Will I need to have this translated!? Is there any format/procedure to this!? Will it have to be translated by my Swiss accountants? - and if so - which parts of the documentation need to be translated!? All US forms are in English. If you're required to provide supporting documentation (during audit, or if the form instructions require it with filing) - you'll need to translate it, and have the translation certified. Depending on what you need, your accountant will guide you. I was told that if I sell the business (and property) after I aquire a greencard - that I will be liable to 15% tax of the profit I'd made. Q) Is this correct!? No. You will be liable to pay income tax. The rate of the tax depends on the kind of property and the period you held it for. It may be 15%, it may be 39%. Depends on a lot of factors. It may also be 0%, in some cases. I also understand that any tax paid (on selling) in Switzerland will be deducted from the 15%!? May be. May be not. What you're talking about is called Foreign Tax Credit. The rules for calculating the credit are not exactly trivial, and from my personal experience - you can most definitely end up being paying tax in both the US and Switzerland without the ability to utilize the credit in full. Again, talk to your tax adviser ahead of time to plan things in the most optimal way for you. I will effectively have ALL the paperwork for this - as we'll need to do the same in Switzerland. But again, it will be in Swiss German. Q) Would this be a problem if its presented in Swiss German!? Of course. If you need to present it (again, most likely only in case of audit), you'll have to have a translation. Translating stuff is not a problem, usually costs $5-$20 per page, depending on complexity. Unless a lot of money involved, I doubt you'll need to translate more than balance sheet/bank statement. I know this is a very unique set of questions, so if you can shed any light on the matter, it would be greatly appreciated. Not unique at all. You're not the first and not the last to emigrate to the US. However, you need to understand that the issue is very complex. Taxes are complex everywhere, but especially so in the US.

The banks must be able to get higher rates from the mortgage otherwise they would buy government bonds. Your question mentions default so I'm assuming a country has reneged on its promise to pay either the principal or interest on government bonds. The main thing to consider is \"\"Who does not get their money?\"\". In other words, who does the government decide not to pay. This is the important part. The government will have some money so they could pay some bond holders. They must decide who to shaft. For example, let's look at who holds Greek government debt. Around 70% of Greek government debt is held outside Greece. See table below. The Greek government could decide to default only on the debt to foreign holders. In that case the banks in France and Switzerland would take the loss on their bonds. This could cause severe problems in France and Switzerland depending on the percentage of Greek bonds that make up the banks' assets. Greek banks would still face losses, however, since the price of their Greek bond holdings would drop sharply when the government defaults. Interestingly, the losses for the Greek banks may be smaller than the losses faced by the French and Swiss banks. This is usually the favored option chosen by government since the French and Swiss don't vote in Greece. Yields on Greek government bonds would rise dramatically. If your Greek mortgage is an adjustable rate mortgage then you could see some big adjustments upward. If you live in France or Switzerland then the bank that owns your mortgage may go under if Greece defaults.

Since you're clearly a Swiss resident, that's easy to do for you. If you don't want to give up making an income, then you have to sacrifice liquidity. There simply aren't any short term (less than 2-3 years) instruments in Swiss Franc that are both safe and yielding a positive income. Which means that you will have to take much more risk then you had with a savings account.

In my opinion, and based on my experience, 10% annually is not an exageration. I start to ask questions only if one talks about return of 30% annually or more. These kind of returns are possible, but very rare. What sort of things do we need to look out for with alternative investment? First the quality of the website and the documentation provided. Then the resume of the founders. Who are those guys? I check their LinkedIn profile. If they have none, I am out. A LinkedIn profile is a minimum if you manage an investment company. I also look for diversification and this is the case with Yieldstreet. How do we assess the risks associated with alternative investments? I would never put more than 10% of my capital in any investment, alternative ones included. I also try to find financial information on the promoter itself. In Yieldstreet case check the legal advisor. I remember an international fraud case I analyse. The promoter I investigated had seven small trust involved: in British Virgin Islands, in Panama, in Holland, in Portugal, in the United States and Canada plus a banking account in Switzerland and the biggest shareholding company in the Isle of Man. No need to talk about what happened after. The investors were all non residents in the juridictions involved and no legal recourse were possible. They lost everything. These promoters regularly change juridictions to avoid detection. As far as Yieldstreet is concerned, what I read and checked seems interesting. Thanks for your question.

The Pathobiological Determinants of Atherosclerosis in Youth Study previously reported risk scores to estimate the probability of advanced atherosclerotic lesions in young individuals aged 15 to 34 years using the coronary heart disease risk factors (gender, age, serum lipoprotein concentrations, smoking, hypertension, obesity, and hyperglycemia). In this study we investigated the relation of these risk scores to the early atherosclerotic lesions. METHODS: We measured atherosclerotic lesions in the left anterior descending coronary artery, right coronary artery, and abdominal aorta and the coronary heart disease risk factors in persons 15 to 34 years of age who died as a result of external causes and were autopsied in forensic laboratories. RESULTS: Risk scores computed from the modifiable risk factors were associated with prevalence of microscopically demonstrable lesions of atherosclerosis (American Heart Association grade 1) in the left anterior descending coronary artery and with the extent of the earliest detectable gross lesion (fatty streaks) in the right coronary artery and abdominal aorta. Risk scores computed from the modifiable risk factors also were associated with prevalence of lesions of higher degrees of microscopic severity (intermediate as well as advanced) in the left anterior descending coronary artery and with extent of lesions of higher degrees of severity (intermediate and raised lesions) in the right coronary artery and abdominal aorta. CONCLUSIONS: Risk scores calculated from traditional coronary heart disease risk factors to identify individual young persons with high probability of having advanced atherosclerotic lesions also are associated with earlier atherosclerotic lesions, including the earliest anatomically demonstrable atherosclerotic lesion.

Objective: We compared the effects of a low-fat vegan diet and conventional diabetes diet recommendations on glycemia, weight, and plasma lipids. Design: Free-living individuals with type 2 diabetes were randomly assigned to a low-fat vegan diet (n = 49) or a diet following 2003 American Diabetes Association guidelines (conventional, n = 50) for 74 wk. Glycated hemoglobin (Hb A1c) and plasma lipids were assessed at weeks 0, 11, 22, 35, 48, 61, and 74. Weight was measured at weeks 0, 22, and 74. Results: Weight loss was significant within each diet group but not significantly different between groups (−4.4 kg in the vegan group and −3.0 kg in the conventional diet group, P = 0.25) and related significantly to Hb A1c changes (r = 0.50, P = 0.001).

STUDY AND DESIGN: Randomized cross-over dietary intervention study. SUBJECTS: Forty-two free-living healthy males aged 35-62 y completed the dietary intervention. Three additional subjects were non-compliant and excluded prior to analysis. INTERVENTIONS: A diet containing lean meat (150 g/d) was compared with one with 290 g/d tofu in an isocaloric and isoprotein substitution. Both diet periods were 1 month, and fat intake was carefully controlled. RESULTS: Seven-day diet records showed the two diets were similar in energy, macronutrients and fibre.

Preloads were matched for weight, calories, water content, and energy density. Weekly measures included blood pressure, weight, anthropometry and 24-hour dietary intakes. Resting energy expenditure, body composition, physical performance and cardiometabolic risk biomarkers were assessed. Results The total amount (grams) of food consumed did not change over time. Yet, after preloads were combined with caloric restriction, average dietary energy density and total energy intakes decreased by 20-29% from baseline values.

While microbiological fecal culture analysis is now increasingly used, little is known about the relationship of changes in intestinal flora, dietary patterns and clinical outcome in specific diseases. To clarify the role of microbiological culture analysis we aimed to evaluate whether in patients with rheumatoid arthritis (RA) or fibromyalgia (FM) a Mediterranean diet or an 8-day fasting period are associated with changes in fecal flora and whether changes in fecal flora are associated with clinical outcome. Methods During a two-months-period 51 consecutive patients from an Integrative Medicine hospital department with an established diagnosis of RA (n = 16) or FM (n = 35) were included in the study. According to predefined clinical criteria and the subjects' choice the patients received a mostly vegetarian Mediterranean diet (n = 21; mean age 50.9 +/-13.3 y) or participated in an intermittent modified 8-day fasting therapy (n = 30; mean age 53.7 +/- 9.4 y). Quantitative aerob and anaerob bacterial flora, stool pH and concentrations of secretory immunoglobulin A (sIgA) were analysed from stool samples at the beginning, at the end of the 2-week hospital stay and at a 3-months follow-up. Clinical outcome was assessed with the DAS 28 for RA patients and with a disease severity rating scale in FM patients. Results We found no significant changes in the fecal bacterial counts following the two dietary interventions within and between groups, nor were significant differences found in the analysis of sIgA and stool ph. Clinical improvement at the end of the hospital stay tended to be greater in fasting vs. non-fasting patients with RA (p = 0.09).

Conclusion Neither Mediterranean diet nor fasting treatments affect the microbiologically assessed intestinal flora and sIgA levels in patients with RA and FM.

There is convincing evidence that vegetarians have lower rates of coronary heart disease, largely explained by low LDL cholesterol, probable lower rates of hypertension and diabetes mellitus, and lower prevalence of obesity. Overall, their cancer rates appear to be moderately lower than others living in the same communities, and life expectancy appears to be greater.

This explains why its incidence is highest and accelerating in the more prosperous countries where intake of fiber has decreased and intake of milled grains and refined sugars has increased over time. Not all patients develop symptoms, but if they do, the most frequent complaints associated with diverticulosis are cramping in the left-lower quadrant, bloating, constipation, and soiling. If diverticula perforate the gut's wall into the pericolic tissue, small and large abscesses, accompanied by bleeding, can form. Fistulization, when it occurs, most often penetrates to the bladder. Treatment addresses symptoms and may require hospitalization. During symptomatic periods, patients do best on low-fiber, bland diets.

Chitin is an eukaryotic extracellular aminosugar biopolymer, massively produced by most fungal systems and by invertebrates, notably arthropods. Being an integral supportive component in fungal cell wall, insect cuticle, and nematode egg shell, chitin has been considered as a selective target for pesticide action. Throughout the elaborate processes of chitin formation and deposition, only the polymerization events associated with the cell membrane compartment are so far available for chemical interference. Currently, the actinomycetes-derived nucleoside peptide fungicides such as the polyoxins and the insecticidal benzoylaryl ureas have reached commercial pesticide status. The polyoxins and other structurally-related antibiotics like nikkomycins are strong competitive inhibitors of the polymerizing enzyme chitin synthase. The exact biochemical lesion inflicted by the benzoylaryl ureas is still elusive, but a post-polymerization event, such as translocation of chitin chains across the cell membrane, is suggested. Hydrolytic degradation of the chitin polymer is essential for hyphal growth, branching, and septum formation in fungal systems as well as for the normal molting of arthropods. Recently, insect chitinase activity was strongly and specifically suppressed by allosamidin, an actimomycetes-derived metabolite. In part, the defense mechanism in plants against invasion of pathogens is associated with induced chitinases. Chitin, chitosan, and their oligomers are able to act as elicitors which induce enhanced levels of chitinases in various plants. Lectins which bind to N-acetyl-D-glucosamine strongly interfere with fungal and insect chitin synthases. Plant lectins with similar properties may be involved in plant-pathogen interaction inter alia by suppressing fungal invasion.", "title": "Chitin synthesis and degradation as targets for pesticide action." }, { "docid": "MED-4220", "text": "OBJECTIVE: Accumulating evidence indicates that prostate cancer is associated with high levels of serum IGF-I. This study was conducted to determine whether a low-fat diet and exercise (DE) intervention may modulate the IGF axis and reduce prostate cancer cell growth in vitro. METHODS: Fasting serum was obtained from 14 men (age 60 +/- 3 years) participating in an 11-day DE program and from eight similarly aged men who had followed the DE program for 14.2 +/- 1.7 years (long-term). Insulin, IGF-I, IGFBP-1, and IGFBP-3 were measured by ELISA, and serum was used to stimulate LNCaP cell growth in vitro. RESULTS: Serum IGF-I levels decreased by 20% while IGFBP-1 increased by 53% after 11-day DE. In the long-term group, IGF-I was 55% lower, while IGFBP-1 was 150% higher relative to baseline. Serum insulin decreased by 25% after 11-day DE and was 68% lower in the long-term group, relative to baseline. No changes in serum IGFBP-3 were observed. Serum-stimulated LNCaP cell growth was reduced by 30% in post-11-day serum and by 44% in long-term serum relative to baseline.

The amount of chicken fat was estimated by emulsification and chloroform/methanol extraction. SETTING: Food sold in supermarkets and farms in England. SUBJECTS: Chicken samples. RESULTS: The fat energy exceeded that of protein. There has been a loss of n-3 fatty acids. The n-6:n-3 ratio was found to be as high as 9:1, as opposed to the recommendation of about 2:1. Moreover, the TAG level in the meat and whole bird mostly exceeded the proportion of phospholipids, which should be the higher for muscle function. The n-3 fatty acid docosapentaenoic acid (DPA, 22 : 5n-3) was in excess of DHA (22 : 6n-3). Previous analyses had, as usual for birds, more DHA than DPA.

The biochemical mechanism for methionine dependency has been studied extensively, but the fundamental mechanism remains unclear. A number of investigators have attempted to exploit the methionine dependence of tumors for therapeutic effects in vivo. To reduce in vivo methionine in plasma and tumours, dietary and pharmacological treatments have been used. Methionine-free diet or methionine-deprived total parenteral nutrition causes regression of a variety of animal tumours. Alternatively, methionine depletion was achieved by the use of methioninase. This enzyme specifically degrades methionine and inhibits tumour growth in preclinical models. Because of potential toxicity and quality of life problems, prolonged methionine restriction with diet or with methioninase is not suitable for clinical use. Methionine restriction may find greater application in association with various chemotherapeutic agents.

After multivariable adjustment, incidence rate ratios (95% CIs) for moderate meat eaters (50-99 g meat/d), low meat eaters (<50 g meat/d), fish eaters, vegetarians, and vegans compared with high-meat eaters (≥100 g meat/d) were 0.96 (0.84, 1.11), 0.85 (0.72, 0.99), 0.79 (0.65, 0.97), 0.70 (0.58, 0.84), and 0.60 (0.38, 0.96), respectively (P < 0.001 for heterogeneity).

The effect of intervention on endothelial function was significant in boys (P=0.0034) but not in girls (P=0.69).

It has been observed that protein restriction also decreases mtROS generation and oxidative stress in rat liver, whereas neither carbohydrate nor lipid restriction change these parameters. This is interesting because protein restriction also increases maximum longevity in rodents (although to a lower extent than DR) and is a much more practicable intervention for humans than DR, whereas neither carbohydrate nor lipid restriction seem to change rodent longevity.

The aims of this study were to clarify the products in tumour and to investigate their effect on tumour proliferation. METHODS: Products formed in the reaction between glucose and methionine or its metabolites were analysed in vitro using gas chromatography. Flatus samples from patients with colon cancer and exhaled air samples from patients with lung cancer were analysed using near-edge x-ray fine adsorption structure spectroscopy and compared with those from healthy individuals. The tumour proliferation rates of mice into which HT29 human colon cancer cells had been implanted were compared with those of mice in which the cancer cells were surrounded by sodium hyaluronate gel to prevent diffusion of gaseous material into the healthy cells. RESULTS: Gaseous sulfur-containing compounds such as methanethiol and hydrogen sulfide were produced when glucose was allowed to react with methionine or its metabolites homocysteine or cysteine. Near-edge x-ray fine adsorption structure spectroscopy showed that the concentrations of sulfur-containing compounds in the samples of flatus from patients with colon cancer and in the samples of exhaled air from patients with lung cancer were significantly higher than in those from healthy individuals.

In the health belief, animal welfare, and religious/other motive categories, low percentages of chronic disease diagnoses were reported: 27%, 11%, and 15%, respectively. There were no significant differences in health behaviors and indices among vegan motive categories, except for product fat content choices. Within the entire study population, health-related vegan motive coincided with regular exercise; 71% normal BMI (mean=22.6); minimal alcohol and smoking practices; frequently consumed vegetables, nuts, and grains; healthy choices in meal types, cooking methods, and low-fat product consumption; and adequate intakes for most protective nutrients when compared to reference values.

Interventions and cross sectional studies on subjects consuming uncooked vegan diet called living food (LF) have been carried out. We have clarified the efficacy of LF in rheumatoid diseases as an example of a health problem where inflammation is one of the main concerns. LF is an uncooked vegan diet and consists of berries, fruits, vegetables and roots, nuts, germinated seeds and sprouts, i.e. rich sources of carotenoids, vitamins C and E. The subjects eating LF showed highly increased levels of beta and alfa carotenes, lycopen and lutein in their sera. Also the increases of vitamin C and vitamin E (adjusted to cholesterol) were statistically significant. As the berry intake was 3-fold compared to controls the intake of polyphenolic compounds like quercetin, myricetin and kaempherol was much higher than in the omnivorous controls. The LF diet is rich in fibre, substrate of lignan production, and the urinary excretion of polyphenols like enterodiol and enterolactone as well as secoisolaricirecinol were much increased in subjects eating LF. The shift of fibromyalgic subjects to LF resulted in a decrease of their joint stiffness and pain as well as an improvement of their self-experienced health. The rheumatoid arthritis patients eating the LF diet also reported similar positive responses and the objective measures supported this finding. The improvement of rheumatoid arthritis was significantly correlated with the day-to-day fluctuation of subjective symptoms.

We conducted a retrospective chart review of patients who came to a family practice office seeking nutritional counseling for weight loss. All of these patients were prescribed an HND diet in an extended counseling session with a family physician. METHODS: A convenience sample (N = 56) of all patients seeking dietary counseling for weight loss from a family practice physician in a 3-year period was included in the chart review. No personal identifying data were recorded. The initial counseling sessions averaged 1 hour in length. Patients were provided with a sample HND daily meal plan and recipes and with verbal and written information about the rationale for the diet. Data recorded from patients' charts at 6-month intervals for up to 2 years of follow-up (when available) included weight, blood pressure, total cholesterol, high-density lipoprotein (HDL) cholesterol, low-density lipoprotein (LDL) cholesterol, triglycerides, and cholesterol:HDL ratio. Non-parametric statistical testing using the Friedman rank order (exact) test for k-related samples was conducted. A follow-up survey on adherence and medication use was completed by 38 patients. RESULTS: Of the 33 patients who returned for follow-up after 1 year, the mean weight loss was 31 lbs (P = .000). Of the 19 patients who returned after 2 years, the mean weight loss was 53 lbs (P = .000), mean cholesterol fell by 13 points, LDL by 15 points, triglycerides by 17 points, and cardiac risk ratio dropped from 4.5 to 3.8. Changes in systolic and diastolic blood pressure were highly significant at all follow-up time intervals (P < or = .001). There was a significant correlation between adherence and degree of weight loss (P = .011). CONCLUSIONS: Weight loss was sustained in patients who returned for follow-up and was more substantial in those who reported good adherence to the recommendations. However, many patients were lost to follow-up. Favorable changes in lipid profile and blood pressure were noted. An HND diet has the potential to provide sustainable, significant, long-term weight loss and may provide substantial lowering of cardiac risk in patients who are motivated and provided with extended one-on-one counseling and follow-up visits. Development of tools to aid in patient retention is an area for possible further study. Clinical trials with long-term follow-up are needed to further test the therapeutic potential and to examine adherence and follow-up issues related to this dietary approach.

The development of a novel screening method that is as economical and non-invasive as the faecal occult blood test (FOBT) for early detection of colorectal cancer (CRC) is needed. A study was undertaken using canine scent detection to determine whether odour material can become an effective tool in CRC screening. Design Exhaled breath and watery stool samples were obtained from patients with CRC and from healthy controls prior to colonoscopy. Each test group consisted of one sample from a patient with CRC and four control samples from volunteers without cancer. These five samples were randomly and separately placed into five boxes. A Labrador retriever specially trained in scent detection of cancer and a handler cooperated in the tests. The dog first smelled a standard breath sample from a patient with CRC, then smelled each sample station and sat down in front of the station in which a cancer scent was detected. Results 33 and 37 groups of breath and watery stool samples, respectively, were tested. Among patients with CRC and controls, the sensitivity of canine scent detection of breath samples compared with conventional diagnosis by colonoscopy was 0.91 and the specificity was 0.99. The sensitivity of canine scent detection of stool samples was 0.97 and the specificity was 0.99. The accuracy of canine scent detection was high even for early cancer. Canine scent detection was not confounded by current smoking, benign colorectal disease or inflammatory disease. Conclusions This study shows that a specific cancer scent does indeed exist and that cancer-specific chemical compounds may be circulating throughout the body.

Treatment of lymphocytes with zingerone (10μg/ml) prior exposure to 2Gy gamma radiation resulted in a significant reduction of frequency of micronuclei as compared to the control set of cells evaluated by cytokinesis blocked micronucleus assay. Similarly, treatment of lymphocytes with zingerone prior to radiation exposure showed significant decrease in the DNA damage as assessed by comet parameters, such as percent tail DNA and Olive tail moment. Further, treatment with zingerone (10μg/ml) before irradiation significantly decreased the percentage of apoptotic cells analyzed microscopically method and by DNA ladder assay. Similarly, the radiation induced reactive oxygen species levels were significantly (P<0.01) inhibited by zingerone. Our study demonstrates the protective effect of zingerone against radiation induced DNA damage and antiapoptotic effect in human lymphocytes, which may be partly attributed to scavenging of radiation induced free radicals and also by the inhibition of radiation induced oxidative stress.

There is a focus in many countries to reduce the level of human illness from food-borne pathogens. Reduction of the prevalence of contaminated poultry meat or eggs is one major area of focus. The other is risk communication to the consumer, where information aimed at changing the food preparation behaviour has been utilised as a risk management tool. The efficacy of messages such as 'cook poultry meat and eggs thoroughly' or 'wash your hands' will depend both on the ability to change consumer behaviour as well as where the risk can best be mitigated. In order to prioritise what message should be given to the consumer, the relative contribution of different exposure pathways finally leading to ingestion of the pathogens and resulting in illness needs to be known. It is important to know whether cross-contamination events or undercooking are the greatest risk lurking in consumers' kitchens. A review of studies looking at the location of pathogens in food products has been performed and data regarding internal and external (surface) contamination of poultry meat with Salmonella spp. and Campylobacter jejuni and C. coli is presented. In the case of eggs, data on internal contamination with Salmonella and for contamination of egg shells with Salmonella and Campylobacter are discussed. The results from published risk assessments for these pathogen-food commodity combinations have been evaluated and conclusions regarding the relative risk of internal and external contamination of poultry meat and eggs were drawn. In conclusion, cross-contamination events from activities such as use of the same cutting board for chicken meat and salad without intermediate cleaning or spreading of pathogens via the kitchen environment seem to be of greater importance than the risk associated with undercooking of poultry meat or eggs.

Regression of adenomas in this syndrome occurs with the administration of nonsteroidal anti-inflammatory drugs and cyclooxygenase-2 inhibitors, but these compounds can have considerable side effects. We evaluated the efficacy of the combination of diet-derived nonprescription supplements curcumin and quercetin to regress adenomas in patients with FAP. METHODS: Five FAP patients with prior colectomy (4 with retained rectum and 1 with an ileal anal pouch) received curcumin 480 mg and quercetin 20 mg orally 3 times a day. The number and size of polyps were assessed at baseline and after therapy. The Wilcoxon signed-rank test was used to determine differences in the number and size of polyps. Treatment side effects and medication compliance also were evaluated. RESULTS: All 5 patients had a decreased polyp number and size from baseline after a mean of 6 months of treatment with curcumin and quercetin. The mean percent decrease in the number and size of polyps from baseline was 60.4% (P < .05) and 50.9% (P < .05), respectively. Minimal adverse side effects and no laboratory abnormalities were noted. CONCLUSIONS: The combination of curcumin and quercetin appears to reduce the number and size of ileal and rectal adenomas in patients with FAP without appreciable toxicity.

All cancer was marginally below the Swedish incidence in offspring of immigrant origin. Decreased SIRs were observed for breast cancer among Norwegian descendants, melanoma among descendants of Hungarian fathers and ovarian and bladder cancer among descendents of Finnish mothers, all consistent with the difference in cancer incidence between Swedes and the indigenous populations. Cervical cancer was increased in daughters of Danish men, whereas thyroid cancer and non-Hodgkin's lymphoma were in excess in offspring of parents of Yugoslav and Asian descent.

METHODS: Diagnosis of neurocysticercosis was established by CT, MRI, and CSF analysis. Psychiatric diagnoses were made by using the present state examination and the schedule for affective disorders and schizophrenia-lifetime version; cognitive state was assessed by mini mental state examination and Strub and Black's mental status examination. RESULTS: Signs of psychiatric disease and cognitive decline were found in 65.8 and 87.5% of the cases respectively. Depression was the most frequent psychiatric diagnosis (52.6%) and 14.2% of the patients were psychotic. Active disease and intracranial hypertension were associated with higher psychiatric morbidity, and previous history of mood disorders was strongly related to current depression. Other variables, such as number and type of brain lesions, severity of neuropsychological deficits, epilepsy, and use of steroids did not correlate with mental disturbances in this sample. CONCLUSIONS: Psychiatric abnormalities, particularly depression syndromes, are frequent in patients with neurocysticercosis. Although regarded as a rare cause of dementia, mild cognitive impairment may be a much more prevalent neuropsychological feature of patients with neurocysticercosis.

After overnight fasting and discontinuation of all medications for ≥12 hours, FMD was assessed using high-resolution linear array ultrasound. Subjects were divided into 2 groups: FMD ≤11.3% (n = 309) and >11.3% (n = 309), where 11.3% is the median FMD, and were comparable regarding CV risk factors, lipoproteins, fasting glucose, C-reactive protein, concomitant medications, and Framingham 10-year risk score. In a mean clinical follow-up of 4.6 ± 1.8 years, the composite CV events (all-cause mortality, nonfatal myocardial infarction, hospitalization for heart failure or angina pectoris, stroke, coronary artery bypass grafting, and percutaneous coronary interventions) were significantly more common in subjects with FMD ≤11.3% rather than >11.3% (15.2% vs 1.2%, p = 0.0001, respectively). Univariate analysis demonstrated that the median FMD significantly predicted CV events (odds ratio 2.78, 95% CI 1.35 to 5.71, p <0.001).

We review here the constituents, pharmacology, safety, and uses of L. barbarum and L. chinense with consideration to the different parts of the plant. Investigations of the fruit have focused on proteoglycans, known as \" Lycium barbarum polysaccharides\", which showed antioxidative properties and some interesting pharmacological activities in the context of age related diseases such as atherosclerosis and diabetes. As to the root bark, several compounds have demonstrated a hepatoprotective action as well as inhibitory effects on the rennin/angiotensin system which may support the traditional use for the treatment of hypertension. While there are no signs of toxicity of this plant, two cases of possible interaction with warfarin point to a potential risk of drug interaction.

DESIGN: Randomized clinical trial, with 3 to 9 years of follow-up. SETTING AND PATIENTS: Between 1983 and 1989, 29 centers enrolled 1441 patients with insulin-dependent diabetes mellitus aged 13 to 39 years, including 726 patients with no retinopathy and a duration of diabetes of 1 to 5 years (primary prevention cohort) and 715 patients with very mild to moderate nonproliferative diabetic retinopathy and a duration of diabetes of 1 to 15 years (secondary intervention cohort). Ninety-five percent of all scheduled examinations were completed. INTERVENTIONS: Intensive treatment consisted of the administration of insulin at least three times a day by injection or pump, with doses adjusted based on self-blood glucose monitoring and with the goal of normoglycemia. Conventional treatment consisted of one or two daily insulin injections. OUTCOME MEASURES: Change between baseline and follow-up visits on the Early Treatment Diabetic Retinopathy Study retinopathy severity scale, assessed with masked gradings of stereoscopic color fundus photographs obtained every 6 months. RESULTS: Cumulative 8.5-year rates of retinopathy progression by three or more steps at two consecutive visits were 54.1% with conventional treatment and 11.5% with intensive treatment in the primary prevention cohort and 49.2% and 17.1% in the secondary intervention cohort. At the 6- and 12-month visits, a small adverse effect of intensive treatment was noted (\"early worsening\"), followed by a beneficial effect that increased in magnitude with time. Beyond 3.5 years of follow-up, the risk of progression was five or more times lower with intensive treatment than with conventional treatment. Once progression occurred, subsequent recovery was at least two times more likely with intensive treatment than with conventional treatment.

Men (n=1218) and women (n=907) ≥60y were included from the National Health and Nutrition Examination Survey 2005–2008. Nutrient intake from 2–24h recalls was used to calculate net endogenous acid production (NEAP) and potential renal acid load (PRAL) (mEq/d). PRAL was calculated from dietary calcium (PRALdiet) and diet + supplemental calcium (PRALtotal). Tests for linear trend in adjusted mean BMD of the hip and lumbar spine were performed across energy adjusted NEAP and PRAL quartiles. Modification by calcium intake (dietary or total) above or below 800 mg/d was assessed by interaction terms. Overall, mean age was 69 ± 0.3y. Among women, there was no association between NEAP and BMD. PRALdiet was positively associated with proximal femur BMD (p trend=0.04). No associations were observed with PRALtotal at any BMD site (P-range: 0.38–0.82). Among men, no significant associations were observed of BMD with NEAP or PRAL. However, an interaction between PRALdiet and calcium intake was observed with proximal femur BMD (p=0.08).

We previously showed that several commercially available frozen broccoli products do not retain the ability to generate the cancer-preventative agent sulforaphane. We hypothesized that this was because the necessary hydrolyzing enzyme myrosinase was destroyed during blanching, as part of the processing that frozen broccoli undergoes. This study was carried out to determine a way to overcome loss of hydrolyzing activity. Industrial blanching usually aims to inactivate peroxidase, although lipoxygenase plays a greater role in product degradation during frozen storage of broccoli. Blanching at 86 °C or higher inactivated peroxidase, lipoxygenase, and myrosinase. Blanching at 76 °C inactivated 92% of lipoxygenase activity, whereas there was only an 18% loss in myrosinase-dependent sulforaphane formation. We considered that thawing frozen broccoli might disrupt membrane integrity, allowing myrosinase and glucoraphanin to come into contact. Thawing frozen broccoli for 9 h did not support sulforaphane formation unless an exogenous source of myrosinase was added. Thermal stability studies showed that broccoli root, as a source of myrosinase, was not more heat stable than broccoli floret.

The senescence phenotype was initially described by Hayflick and Moorhead in 1961 on human fibroblasts undergoing replicative exhaustion in culture [2]. It has been shown that senescence can be triggered in different cell types in response to diverse forms of cellular damage or stress (for review see [1]). Importantly, while senescence was denounced as a tissue culture phenomenon for many years, recent in vivo studies demonstrated that cellular senescence represents a potent failsafe mechanism against tumorigenesis and contributes to the cytotoxicity of certain anticancer agents (see for example [3-7]). Interestingly, senescent cells have also been observed in certain aged or damaged tissues and there is growing evidence that senescence checkpoints can affect the regenerative reserve of tissues and organismal aging [8-11]. However, senescence may also have positive effects on organ maintenance by limiting pathological responses to acute forms of injury such as fibrotic scarring in response to chemical induced liver injury [12]. Over the past years it was also shown that senescent cells can communicate with their environment by secreting a myriad of cytokines and growth factors. Interestingly, this \"senescence associated secretory phenotype (SASP)\" seems to be a double edged sword regarding tumor initiation and maintenance: i) On the one hand, it has been shown that the SASP can have pro-tumorigenic effects. In an experimental system it was shown that senescent mesenchymal cells can enhance the tumorigenicity of surrounding breast cancer cells [13]. ii) Similarly, it is possible that the SASP enhances selection of transformed cell clones in aged organ systems. It has been shown that loss of proliferative competition of non-transformed cells can accelerate leukemogenesis [14]. It remains to be seen whether aberrant secretion of cytokines and growth factors by the SASP can accelerated this process in aged and chronically damage organ systems. iii) In contrast to its pro-tumorigenic aspect, the SASP could also have anti-tumor effects. A recent study showed that in a mosaic liver cancer mouse model the activation of p53 induced senescence, an upregulation of inflammatory cytokines, and activation of innate immune responses leading to tumour cell clearance [15]. iv) In further support that the SASP could have anti-tumor activities, a series of recent papers showed that components of the SASP can stabilize the senescence cell cycle arrest via an autoregulatory feedback loop [16,17] or induces apoptosis of tumor cells [18]. In addition to its effects on tumorigenesis, the SASP could also influence tissue aging. Studies on aging telomere dysfunctional mice have provided direct experimental evidence for an in vivo activation of the SASP in response to telomere dysfunction [19]. Interestingly, this in vivo SASP provoked alterations in stem cell differentiation (skewing of hematopoiesis towards reduction in lymphopoiesis and enhancement of myelopoiesis) that are also characteristic signs of human aging. Figure 1. Different cellular stresses can induce senescence including telomere shortening, DNA damage, and oncogene activation. Senescence of tumor cells ... In light of the many possible roles o the SASP in aging and carcinogenesis, it appears to be of utmost importance to decipher regulatory pathways controlling the SASP. In a current publication, Bhaumik et al. have identified 2 microRNAs (miR-146a/b) that negatively regulate the secretion of IL-6 and IL-8 - two of the SASP [20]. The authors show that these microRNAs are up-regulated at late stages of senescence, many days after a permanent cell cycle arrest has been established. Interestingly, the inhibitory miRs are most strongly up-regulated in senescence of cell lines that show a strong SASP but not in cell lines characterized by a weak SASP. The authors propose a new concept indicating that miRs 146a and b function in a negative feedback loop preventing an over-activation of the SASP in senescent cells. The authors present some initial data suggesting that activation of this negative feedback loop involves IL-1 receptor, IRAK-1, and NFκB signalling leading to an up-regulation of miRs-146a and b. A direct proof that this proposed feedback loop suppresses over-activation of the SASP remains to be demonstrated in future studies. The authors show that blockage of IL-1-receptor signalling prevents both the up-regulation of miRs-146a and b as well as Il-6 secretion. To confirm their new concept, it would be important to show that a selective blockage of miRs-146a and b results in over-activation of the SASP. The work by Bhaumik et al. places mir-146a/b as central players to control IL-6 and IL-8 expression within the SASP. MicroRNAs are emerging therapeutic targets because their expression levels can be effectively modulated via the use of antagomirs (see for example [21]). Also, for increasing microRNA expression, microRNAs can be delivered into cellsin vivo (see for example [22]). Therefore, it will be interesting to functionally test the impact of mir-146 inhibition on tumorigenesis and aging in relevant mouse models. Such studies will be of particular interest, as recent work showed that IL-6 secretion by senescent cells is relevant for initiating and maintaining the senescene response via an autocrine loop [17]. A reduction of miR-146 could increase IL-6 levels in senescent cells, which should stabilize the senescence program and reduce the risk of malignant transformation. Furthermore, it can be speculated that reduction of mir-146 a/b will increase NfκB activation via IRAK1. As NfκB is modulating the expression of various inflammation associated genes, this may also lead to increased clearance of senescent tumor cells by the innate immune system. However, it should be mentioned that Il-6 secreted by senescent cells can also act as a mitogen for surrounding cells, thus potentially increasing the risk of malignant transformation [13,17]. Besides its function in SASP modulation, miR-146 was also reported to target the mRNAs of the BRCA1 and BRCA2 tumor suppressors. In a recent study a G to C polymorphism in miR-146, which leads to an increased processing and release of the mature microRNA, can predict an early onset of breast cancer [23]. Taken together, the study of Bhaumik et al. opens an interesting new research area dealing with the gene regulatory mechanisms that control activation of the SASP. Given the diverse roles of the SASP in modulating tumor progression, immune surveillance of damaged cells, and the stabilization of the senescence arrest itself, it will be of great interest to analyse the influence of SASP regulatory pathways during aging and cancer.", "title": "Keeping your senescent cells under control" }, { "docid": "41710132", "text": "The tumor suppressor PML (promyelocytic leukemia protein) regulates cellular senescence and terminal differentiation, two processes that implicate a permanent exit from the cell cycle.

Here, we observed that the premature growth arrest in hMSCs occurs in parallel with the induction of p16INK4a, following abrogation of inhibitory phosphorylation of retinoblastoma protein. These stress responses were concurrent with increased formation of reactive oxygen species (ROSs) from mitochondria and increased p38 mitogen-activated protein kinase (MAPK) activity. The introduction of Wip1 (wild-type p53 inducible phosphatase-1), a well-studied stress modulator, significantly lowered p16INK4a expression and led to p38 MAPK inactivation, although it failed to affect the levels of ROSs. Moreover, the suppression of stress responses by Wip1 apparently extended the life span of hMSCs, compared with control conditions, while maintaining their multilineage differentiation potential.

We then tested the hypothesis that increasing cellular levels of miRNA-22 would achieve neuroprotection in in vitro models of neurodegeneration. As predicted, overexpression of miR-22 inhibited neurodegeneration in primary striatal and cortical cultures exposed to a mutated human huntingtin fragment (Htt171-82Q). Overexpression of miR-22 also decreased neurodegeneration in primary neuronal cultures exposed to 3-nitropropionic acid (3-NP), a mitochondrial complex II/III inhibitor. In addition, miR-22 improved neuronal viability in an in vitro model of brain aging. The mechanisms underlying the effects of miR-22 included a reduction in caspase activation, consistent with miR-22's targeting the pro-apoptotic activities of mitogen-activated protein kinase 14/p38 (MAPK14/p38) and tumor protein p53-inducible nuclear protein 1 (Tp53inp1).

Because senescent cells accumulate in multiple tissues with aging, these cells and the dysfunctional factors they secrete, termed the senescence-associated secretory phenotype (SASP), are increasingly recognized as promising therapeutic targets to prevent age-related degenerative pathologies, including osteoporosis. However, the cell type(s) within the bone microenvironment that undergoes senescence with aging in vivo has remained poorly understood, largely because previous studies have focused on senescence in cultured cells. Thus in young (age 6 months) and old (age 24 months) mice, we measured senescence and SASP markers in vivo in highly enriched cell populations, all rapidly isolated from bone/marrow without in vitro culture. In both females and males, p16Ink4a expression by real-time quantitative polymerase chain reaction (rt-qPCR) was significantly higher with aging in B cells, T cells, myeloid cells, osteoblast progenitors, osteoblasts, and osteocytes. Further, in vivo quantification of senescence-associated distension of satellites (SADS), ie, large-scale unraveling of pericentromeric satellite DNA, revealed significantly more senescent osteocytes in old compared with young bone cortices (11% versus 2%, p < 0.001). In addition, primary osteocytes from old mice had sixfold more (p < 0.001) telomere dysfunction-induced foci (TIFs) than osteocytes from young mice. Corresponding with the age-associated accumulation of senescent osteocytes was significantly higher expression of multiple SASP markers in osteocytes from old versus young mice, several of which also showed dramatic age-associated upregulation in myeloid cells. These data show that with aging, a subset of cells of various lineages within the bone microenvironment become senescent, although senescent myeloid cells and senescent osteocytes predominantly develop the SASP. Given the critical roles of osteocytes in orchestrating bone remodeling, our findings suggest that senescent osteocytes and their SASP may contribute to age-related bone loss. © 2016 American Society for Bone and Mineral Research.", "title": "Identification of Senescent Cells in the Bone Microenvironment." }, { "docid": "207972", "text": "Early region 3 (E3) of group C human adenoviruses (Ad) encodes several inhibitors of tumor necrosis factor alpha (TNF-alpha) cytolysis, including an E3 14.7-kDa protein (E3-14.7K) and a heterodimer containing two polypeptides of 10.4 and 14.5 kDa. To understand the mechanism by which the viral proteins inhibit TNF-alpha functions, the E3-14.7K protein was used to screen a HeLa cell cDNA library to search for interacting proteins in the yeast two-hybrid system. A novel protein containing multiple leucine zipper domains without any significant homology with any known protein was identified and has been named FIP-2 (for 14.7K-interacting protein). FIP-2 interacted with E3-14.7K both in vitro and in vivo. It colocalized with Ad E3-14.7K in the cytoplasm, especially near the nuclear membrane, and caused redistribution of the viral protein. FIP-2 by itself does not cause cell death; however, it can reverse the protective effect of E3-14.7K on cell killing induced by overexpression of the intracellular domain of the 55-kDa TNF receptor or by RIP, a death protein involved in the TNF-alpha and Fas apoptosis pathways. Deletion analysis indicates that the reversal effect of FIP-2 depends on its interaction with E3-14.7K. Three major mRNA forms of FIP-2 have been detected in multiple human tissues, and expression of the transcripts was induced by TNF-alpha treatment in a time-dependent manner in two different cell lines.

We previously reported the antimetastatic activity of the PPARalpha ligand, fenofibrate, against melanoma tumors in vivo. Here we investigated possible molecular mechanisms of fenofibrate anti metastatic action. EXPERIMENTAL DESIGN Monolayer cultures of mouse (B16F10) and human (SkMell88) melanoma cell lines, soft agar assay, and cell migration assay were used in this study. In addition, we analyzed PPARalpha expression and its transcriptional activity in response to fenotibrate by using Western blots and liciferase-based reporter system. RESULTS Fenofibrate inhibited migration of B16F10 and SkMel188 cells in Transwell chambers and colony formation in soft agar. These effects were reversed by PPAR inhibitor, GW9662. Western blot analysis revealed time-dependent down-regulation of Akt and extracellular signal-regulated kinase l/2 phosphorylation in fenofibrate-treated cells. A B16F10 cell line stably expressing constitutively active Akt mutant was resistant to fenofibrate. In contrast, Akt gene silencing with siRNA mimicked the fenofibrate action and reduced the migratory ability of B16F1O cells. In addition, fenofibrate strongly sensitized BI6FIO cells to the proapoptotic drug staurosporine, further supporting the possibility that fenofibrate-induced down-regulation of Akt function contributes to fenofibrate-mediated inhibition of metastatic potential in this experimental model.

METHODS AND RESULTS Intracellular calcium in isolated cardiomyocytes was measured with a spectrofluorometric method using Fura-2. Myocyte contractility was measured with a video edge system. NaHS (50 µM, an H(2)S donor) had no significant effect on the resting calcium level, electrically induced (EI) calcium transients, and cell contractility in ventricular myocytes. Stimulating endogenous NO production with l-arginine or exogenous application of NO donors [sodium nitroprusside (SNP) and 2-(N,N-diethylamino)-diazenolate-2-oxide] decreased myocyte twitch amplitudes accompanied by slower velocities of both cell contraction and relaxation. Surprisingly, NaHS reversed the negative inotropic and lusitropic effects of the above three NO-increasing agents. In addition, the mixture of SNP + NaHS increased, whereas SNP alone decreased, the resting calcium level and the amplitudes of EI calcium transients. Angeli's salt, a nitroxyl anion (HNO) donor, mimicked the effect of SNP + NaHS on calcium handling and myocyte contractility. Three thiols, N-acetyl-cysteine, l-cysteine, and glutathione, abolished the effects of HNO and SNP + NaHS on myocyte contraction. Neither Rp-cAMP [a protein kinase A (PKA) inhibitor] nor Rp-cGMP [a protein kinase G (PKG) inhibitor] affected the effects of SNP + NaHS, suggesting a cAMP/PKA- or cGMP/PKG-independent mechanism.

Loans like mortgages generally have a very simple principle behind them: at any given time, the interest charged at that time is the product of the amount still owing and the interest rate. So for example on a mortgage of $100,000, at an interest rate of 5%, the interest charged for the first year would be $5,000. If you pay the interest plus another $20,000 after the first year, then in the second year the interest charge would be $4,000. This view is a bit of an over-simplification, but it gets the basic point across. [In practice you would actually make payments through the year so the actual balance that interest is charged on would vary. Different mortgages would also treat compounding slightly differently, e.g. the interest might be added to the mortgage balance daily or monthly.] So, it's natural that the interest charged on a mortgage reduces year-by-year as you pay off some of the mortgage. Mortgages are typically setup to have constant payments over the life of the mortgage (an \"\"amortisation schedule\"\"), calculated so that by the end of the planned mortgage term, you'll have paid off all of the principal. It's a straightforward effect of the way that interest works in general that these schedules incorporate higher interest payments early on in the mortgage, because that's the time when you owe more money. If you go for a 15-year mortgage, each payment will involve you paying off significantly more principal each time than with a 30-year mortgage for the same balance - because with a 15-year mortgage, you need to hit 0 after 15 years, not 30. So since you pay off the principal faster, you naturally pay less interest even when you just compare the first 15 years. In your case what you're talking about is paying off the mortgage using the 30-year payments for the first 15 years, and then suddenly paying off the remaining principal with a lump sum. But when you do that, overall you're still paying off principal later than if it had been a 15-year mortgage to begin with, so you should be charged more interest, because what you've done is not the same as having a 15-year mortgage. You still will save the rest of the interest on the remaining 15 years of the term, unless there are pre-payment penalties. For the car loan I'm not sure what is happening. Perhaps it's the same situation and you just misunderstood how it was explained. Or maybe it's setup with significant pre-payment penalties so you genuinely don't save anything by paying early.\"", "title": "" }, { "docid": "366869", "text": "There is no interest outstanding, per se. There is only principal outstanding. Initially, principal outstanding is simply your initial loan amount. The first two sections discuss the math needed - just some arithmetic. The interest that you owe is typically calculated on a monthly basis. The interested owed formula is simply (p*I)/12, where p is the principal outstanding, I is your annual interest, and you're dividing by 12 to turn annual to monthly. With a monthly payment, take out interest owed. What you have left gets applied into lowering your principal outstanding. If your actual monthly payment is less than the interest owed, then you have negative amortization where your principal outstanding goes up instead of down. Regardless of how the monthly payment comes about (eg prepay, underpay, no payment), you just apply these two calculations above and you're set. The sections below will discuss these cases in differing payments in detail. For a standard 30 year fixed rate loan, the monthly payment is calculated to pay-off the entire loan in 30 years. If you pay exactly this amount every month, your loan will be paid off, including the principal, in 30 years. The breakdown of the initial payment will be almost all interest, as you have noticed. Of course, there is a little bit of principal in that payment or your principal outstanding would not decrease and you would never pay off the loan. If you pay any amount less than the monthly payment, you extend the duration of your loan to longer than 30 years. How much less than the monthly payment will determine how much longer you extend your loan. If it's a little less, you may extend your loan to 40 years. It's possible to extend the loan to any duration you like by paying less. Mathematically, this makes sense, but legally, the loan department will say you're in breach of your contract. Let's pay a little less and see what happens. If you pay exactly the interest owed = (p*I)/12, you would have an infinite duration loan where your principal outstanding would always be the same as your initial principal or the initial amount of your loan. If you pay less than the interest owed, you will actually owe more every month. In other words, your principal outstanding will increase every month!!! This is called negative amortization. Of course, this includes the case where you make zero payment. You will owe more money every month. Of course, for most loans, you cannot pay less than the required monthly payments. If you do, you are in default of the loan terms. If you pay more than the required monthly payment, you shorten the duration of your loan. Your principal outstanding will be less by the amount that you overpaid the required monthly payment by. For example, if your required monthly payment is $200 and you paid $300, $100 will go into reducing your principal outstanding (in addition to the bit in the $200 used to pay down your principal outstanding). Of course, if you hit the lottery and overpay by the entire principal outstanding amount, then you will have paid off the entire loan in one shot! When you get to non-standard contracts, a loan can be structured to have any kind of required monthly payments. They don't have to be fixed. For example, there are Balloon Loans where you have small monthly payments in the beginning and large monthly payments in the last year. Is the math any different? Not really - you still apply the one important formula, interest owed = (p*I)/12, on a monthly basis. Then you break down the amount you paid for the month into the interest owed you just calculated and principal. You apply that principal amount to lowering your principal outstanding for the next month. Supposing that what you have posted is accurate, the most likely scenario is that you have a structured 5 year car loan where your monthly payments are smaller than the required fixed monthly payment for a 5 year loan, so even after 2 years, you owe as much or more than you did in the beginning! That means you have some large balloon payments towards the end of your loan. All of this is just part of the contract and has nothing to do with your prepay. Maybe I'm incorrect in my thinking, but I have a question about prepaying a loan. When you take out a mortgage on a home or a car loan, it is my understanding that for the first years of payment you are paying mostly interest. Correct. So, let's take a mortgage loan that allows prepayment without penalty. If I have a 30 year mortgage and I have paid it for 15 years, by the 16th year almost all the interest on the 30 year loan has been paid to the bank and I'm only paying primarily principle for the remainder of the loan. Incorrect. It seems counter-intuitive, but even in year 16, about 53% of your monthly payment still goes to interest!!! It is hard to see this unless you try to do the calculations yourself in a spreadsheet. If suddenly I come into a large sum of money and decide I want to pay off the mortgage in the 16th year, but the bank has already received all the interest computed for 30 years, shouldn't the bank recompute the interest for 16 years and then recalculate what's actually owed in effect on a 16 year loan not a 30 year loan? It is my understanding that the bank doesn't do this. What they do is just tell you the balance owed under the 30 year agreement and that's your payoff amount. Your last sentence is correct. The payoff amount is simply the principal outstanding plus any interest from (p*I)/12 that you owe. In your example of trying to payoff the rest of your 30 year loan in year 16, you will owe around 68% of your original loan amount. That seems unfair. Shouldn't the loan be recalculated as a 16 year loan, which it actually has become? In fact, you do have the equivalent of a 15 year loan (30-15=15) at about 68% of your initial loan amount. If you refinanced, that's exactly what you would see. In other words, for a 30y loan at 5% for $10,000, you have monthly payments of $53.68, which is exactly the same as a 15y loan at 5% for $6,788.39 (your principal outstanding after 15 years of payments), which would also have monthly payments of $53.68. A few years ago I had a 5 year car loan. I wanted to prepay it after 2 years and I asked this question to the lender. I expected a reduction in the interest attached to the car loan since it didn't go the full 5 years. They basically told me I was crazy and the balance owed was the full amount of the 5 year car loan. I didn't prepay it because of this. That is the wrong reason for not prepaying. I suspect you have misunderstood the terms of the loan - look at the Variable Monthly Payments section above for a discussion. The best thing to do with all loans is to read the terms carefully and do the calculations yourself in a spreadsheet. If you are able to get the cashflows spelled out in the contract, then you have understood the loan.", "title": "" }, { "docid": "65578", "text": "There is one basic principle to apply here: to compare money paid at different times, all the amounts must be compounded or discounted to the same point in time. In this case, the moment of the initial $225,000 loan is convenient. At that moment, you get $225,000 You then make 30 payments on the 40% mortgage. The amount of these payments has to be calculated; they're paying off a $90,000 mortgage with 30 monthly payments at a monthly rate of 0.5% Finally, you make 30 payments of an amount X, starting one month after the 40% mortgage ends. So far we've just listed the amount and time of all the payments back and forth. A time-line type diagram is a huge help here.

Equate money in with money out and solve for X", "title": "" }, { "docid": "368770", "text": "\"The answer depends on what else you'd do with that 2%. But first, let's look at some actual numbers. For simplicity's sake, let's say you have a £100k mortgage outstanding, your payment is £1000 per month, and you want to pay £1000 extra per month. 2% interest, compounded monthly for simplicity, so .02/12 = .00167% per month. (Your interest is probably compounded daily, but this simplifies the math and isn't too far off of it.) If you don't pay it off early, then first month, you'll owe £100167, minus £1000, so £99167. Second month, £99332 after interest, then £98332 after payment. So on and so forth. After 24th month (2 years), you'll owe £79613 after that 24th payment. So you've paid off £20,000 of balance, at the cost of £24,000; total interest paid, £3,613. If you do pay off another £1000, so you put a total of £2000 in per month, which is penalized (.02*1000=£20) each payment, for a total of £48,000 paid over the 24 months. After that 24 months, you have a balance of £55,637, so a bit over £44k paid off, at the cost of £48k; total interest and fees paid, £3,637. So, at the end of the 24 month period, you've paid an extra £24 in interest/fees than you would have otherwise. You of course have a lower loan balance at the end, but you haven't saved any money overall, and if you're just refinancing at this point into a new loan, you're no better off (and very slightly worse off), even assuming the money will just sit in your bank account and do nothing. I think with daily compounding interest it will be around the same or slightly better, but it's not a significant amount. Now, there is a third option, perhaps: pay £24000 (so after penalty, £23,520) on the first month. This is that whole extra £1000 per month, all up front, where it makes the most difference for interest. This does help, some: you pay £3,172 in interest, around £450 less. Sounds good to me, right? Except, you might be able to make more than £450 with that £24,000. £450 is 1.875% of £24,000, meaning you just need to make a 2% return on your money to beat out this option (and in fact, that's not surprising, given the 2% interest rate!). Investing in the market, even conservatively, is likely, though not guaranteed, to be beneficial; over a 2 year period it's fairly risky, though if you can think over 5-10 years, it's very likely to be substantially better. Even a 4-5% return (well below long-term market averages) will be quite a bit better, and the market's down quite a bit right now - so it might be even better than that - though it's still a risk. You can make a term deposit (looks like \"\"Fixed rate bond\"\" is the term), even, and at least break even - right now it looks like 1.9% is common for a 2 year term deposit in the UK. In total - my recommendation would be against paying off the mortgage early, particularly in this 2% interest rate period. 2% is around inflation levels, meaning you're not really paying any real interest, from one point of view. Once the rates are higher (4%+) then it may be worth considering. The exception here - basically the standard exception to these questions - is if you are otherwise going to spend the money on luxuries. In that case, you're better off prepaying the mortgage, at least from a personal finance perspective, if you can do so up front - but not if you're going to do it monthly.

The 6.8 percent rate is useful for doing calculations after the loan fees have been charged, though. These calculations include the capitalized interest and the monthly payment amounts. A true calculation of the APR would take the loan fees into account, and give a higher number than 6.8 percent.

The basics of the formula are the periodic payment amount, A (your monthly payment), can be determined by the principal loan, P, the rate, r, and the number of payments, n. Lenders lend money to make a profit on the interest. They'd like to get back all the money they lent out. Amortization schedules are popular because the fixed low payments make it easier for borrowers to pay the loan off eventually. They also tend to be very profitable for lenders, especially at the start of the term, because they make a lot of profit on interest, just like the start of your mortgage. The principal of a mortgage has more meaning than the principal of a revolving debt credit card. The mortgage principal is fixed at the start, and represents the value of the collateral property that is your home. You could consider the amount of principal paid to be the percentage of your home that you actually own (as part of your net worth calculation). A credit card has a new balance each month depending on how much you charge and how much you pay off. Principal has less meaning in this case, because there is no collateral to compare against, and the balance will change monthly. In this case, the meaning of the amortization schedule on your credit card is how long it will take you to pay off the balance if you stop charging and pay at the proscribed payment level over the term described. Given the high interest rate on credit cards, you may end up paying twice as much for goods in the long run if you follow your lenders schedule. Amortizing loans are common for consumer loans, unless a borrower is seeking out the lowest possible monthly payment.

Also, it sounds like your friend is a tool. I hope this \"\"friend\"\" is not also your financial advisor... they would be encouraging you to make a very poor investment decision. They also don't know how to do financial math. For what it's worth, I am not wrong. I have correctly answered a set of changing questions as you have asked them... Your friend is answering based on a third, completely different investment model, which you proposed in the edit to your last post. If that's what you meant all along, then you should have been more clear in the questions you were asking. Please let me layout the following: How the previous questions//investment proposals were built How to analyze this current proposal What your other option is Why the other option is best in a 'real world' market The First Question My understanding of the initial proposal was to take out a $10,000 loan, invest the proceeds, and expect to not have any money of your own tied up in this. Because that OP did not specify that this is an interest-only loan (you still haven't in any of your questions), the bank will require you to make payments back to them each month that include principal and interest. Your \"\"friend\"\" is talking about the total interest paid being the only cost of a loan. While that is (almost) true, regardless of what your friend says, significantly more cash is involved in making sure that all the payments are made on time---unless you set up an interest-only loan. But with the set up laid out in this post, and with the assumptions I specified there, the principal payments must be included because the borrower has to pay back the bank and isn't not tying up any of their own money. In that case, my initial analysis is correct--your breakeven is in the low teens for an annual required return. The Second Proposal Your second proposal... before any edits... refined things a little bit, to try to capture the any possible returns by not selling something. As I indicated there, (with what was an exaggerating assumption), the lack of clarity makes for an outlandish required return. The Second Proposal...with edits, or the one proposed above I will get to the one proposed above in a second, but first let me highlight a few problems with your friend's analysis. Simple interest: the only place (in the US at least) that will lend with simple interest is student loans. Any loan that you actually take out will be compound interest. Not an interest only loan: your \"\"friend\"\" is not calculating interest correctly. Since this isn't an interest-only loan, the principal balance will reduce every time you make a payment, by ~$320-$340 each month. This substantially reduces the total interest paid, to $272.79 over the total 24 months. \"\"Returns\"\": I don't know what country, or what business your friend works in, but \"\"returns\"\" are a very ambiguous concept. Investopedia defines returns as gains or losses. (I wish I could inhabit the lala land that your friend lives in when returns are always positive). TheFreeDictionary.com defines a return for finance as \"\"The change in the value of a portfolio over an evaluation period, including any distributions made from the portfolio during that period.\"\" When you have not made it clear that any other money is being used in this investment plan (as was the case in scheme #1 and scheme #2a,) the loan still has to be paid. So, clearly the principal must be included in the return calculations. How to evaluate this proposed investment scheme Key dimensions: Loan ($8,000 ... 24 months ... 0.27% monthly rate... monthly compounding... no loan origination fees) Monthly payment (PMT in Excel yields $344.70). Investment capital (starting = $8,000) Monthly Return (Investment yields... we hope it's positive!) Your monthly contribution from your salary Taxes = 10%. Transaction Fees = $20 Go and lookup how to build an amortization table for a loan in Excel. Your life will be infinitely better for it. Now, you get this loan set up and invested into something... (it costs $20 to buy the assets). So you've got $7980 chugging away earning interest. I calculate that your break even, with you paying in $344.70 of your own money each month is 1.81% annually, or 3.42% over the 24 month life of this scheme. That is using monthly compound interest for the payments, because that's what the real world would use, and using monthly compounding of the investments' returns. Your total interest expense would be $272.79. This seems feasible. But let's talk about what your other option is, given that you're ready to spend $344.70 each month on an investment. Your other option I understand the appeal of getting $8,000... right away... to invest in something. But the risk behind this is that if the market goes down (and markets do) you're stuck paying a fixed amount for your loan that is now worth less money. Your other option is to take your $344.70, and invest it step-by-step. (You would want to skip a month or two buying assets in the market, so that you can lessen transaction costs). This has two advantages: (1) you save yourself $272 in interest. (2) When the market goes down, you still win. With this strategy, you still win when the market goes down because of what is commonly called \"\"dollar cost averaging\"\". When the market is up, your investments are also up. When the market goes down, your previous investments decrease in value but you can invest new money at the lower rates. Why the step-by-step, invest your own money strategy is better At low rates (when you're looking for your break-even), the step-by-step model outperforms the loan. At higher rates of return (~4% + per year), you get the benefit of having the borrowed money earning more gains. In fact, for every continuous (meaning set... not changing month-to-month) interest rate that you can dream up that is greater than about 4% per year, the borrowed money earns more. At 10% per year, the borrowed money will earn about $500 more over the 2 years than your step by step investment would. BUT I recognize that you might feel like the market will always go up. That's what everyone thinks. And that's alright. But have one really bad month, or a couple of just-not-great-months, and your fixed 'loan' portfolio will underperform. Have a few really bad months, and your portfolio could be substantially reduced in value... but you would still be paying the same amount for it each month.

How can I use time value of money to find the present value of money if I choose to go with option A? First of all, I'd question your discount rate. A 12% discount rate means that you can safely reinvest the money that you're not spending today at a 12% annual (1% monthly) rate, which seems very high. Normally for short-term spending decisions you'd use a risk-free rate, which would be closer to 1%-2%.

You could calculate it with a different compounding period but it gets much more complicated and probably wouldn't make a significant difference.

You are usually OK to do things that have at least a short-term positive effect, like paying down debt. But refinancing - which would require applying for a non-home loan - is exactly the sort of hard-pull that can drop your credit rating. It is not generally advised. The exception to this is would be if you have an especially unusual situation with an existing loan (like your car), that is causing a deal-breaking situation with your home loan. This would for example be having a car payment so high that it violates maximum Debt-to-Income ratios (DTI). If your monthly debt payments are more than 43% of your monthly income, for instance, you will generally be unable to obtain a \"\"qualified mortgage\"\", and over 28-36% will disqualify you from some lenders and low-cost mortgage options. The reason this is unusual is that you would have to have a bizarrely terrible existing loan, which could somehow be refinanced without increasing your debt while simultaneously providing a monthly savings so dramatic that it would shift your DTI from \"\"unacceptable\"\" to \"\"acceptable\"\". It's possible, but most simple consumer loan refis just don't give that kind of savings. In most cases you should just \"\"sit tight\"\" and avoid any new loans or refinances while you seek a home purchase. If you want to be sure, you'll need to figure out your DTI ratio (which I recommend anyway) and see where you would be before and after a car refinance. If this would produce a big swing, maybe talk with some mortgage loan professionals who are familiar with lending criteria and ask for their opinion as to whether the change would be worth it. 9 times out of 10, you should wait until after your loan is closed and the home is yours before you try to refinance your car. However I would only warn you that if you think your house + car payment is too much for you to comfortably afford, I'd strongly recommend you seriously reconsider your budget, current car ownership, and house purchasing plans.

Any money that your brother transfers to you to pay off your loans, add to that personal loan, and later on once your loans are paid off you start repaying the loan to him and he uses the proceeds for his own loans. The interest rate will determine how the benefit of paying off the 10% loans is shared: if the rate is set at 10% then your brother will get all the benefit, if 5% you will get all the benefit, and 7.5% would roughly share it out. This means that you can still manage your own student loans separately. Your brother can choose how little or much to commit to the snowball rather than his own loans (of course he should first make the minimum payments on his own loans). Anything he does loan you benefits you both if we ignore the credit and tax issues - he gets more than the 5% interest on his own loans, and you pay less than the 10% interest on your loans.

He claims that by applying the $2000 USD per month towards reducing the debt, it would take him 30-36 months to be debt-free. But is it not the case that applying the $2000 to the student loan of $18K+ (while continuing to make the auto loan payments) will pay the student loan off in less than 10 months? If no payments are made on that $18K+ student loan, the accrued interest of about $2K in 10 months (this is (18.25*13.7%*)(10/12) for a total of $20K+). In actuality, with the loan being paid down, the interest will be much less. Once the student loan is paid off, the extra $2000 can go towards what is left of the $10K auto loan each month and pay it off in another 4 or 5 months or so.

Cost effectiveness evaluations based on cRCT data lack external validity.
[ { "docid": "15048300", "text": "BACKGROUND Data on absolute risks of outcomes and patterns of drug use in cost-effectiveness analyses are often based on randomised clinical trials (RCTs). The objective of this study was to evaluate the external validity of published cost-effectiveness studies by comparing the data used in these studies (typically based on RCTs) to observational data from actual clinical practice. Selective Cox-2 inhibitors (coxibs) were used as an example. METHODS AND FINDINGS The UK General Practice Research Database (GPRD) was used to estimate the exposure characteristics and individual probabilities of upper gastrointestinal (GI) events during current exposure to nonsteroidal anti-inflammatory drugs (NSAIDs) or coxibs. A basic cost-effectiveness model was developed evaluating two alternative strategies: prescription of a conventional NSAID or coxib. Outcomes included upper GI events as recorded in GPRD and hospitalisation for upper GI events recorded in the national registry of hospitalisations (Hospital Episode Statistics) linked to GPRD. Prescription costs were based on the prescribed number of tables as recorded in GPRD and the 2006 cost data from the British National Formulary. The study population included over 1 million patients prescribed conventional NSAIDs or coxibs. Only a minority of patients used the drugs long-term and daily (34.5% of conventional NSAIDs and 44.2% of coxibs), whereas coxib RCTs required daily use for at least 6-9 months. The mean cost of preventing one upper GI event as recorded in GPRD was US$104k (ranging from US$64k with long-term daily use to US$182k with intermittent use) and US$298k for hospitalizations. The mean costs (for GPRD events) over calendar time were US$58k during 1990-1993 and US$174k during 2002-2005. Using RCT data rather than GPRD data for event probabilities, the mean cost was US$16k with the VIGOR RCT and US$20k with the CLASS RCT. CONCLUSIONS The published cost-effectiveness analyses of coxibs lacked external validity, did not represent patients in actual clinical practice, and should not have been used to inform prescribing policies. External validity should be an explicit requirement for cost-effectiveness analyses.", "title": "A Comparison of Cost Effectiveness Using Data from Randomized Trials or Actual Clinical Practice: Selective Cox-2 Inhibitors as an Example" } ]

They are sometimes challenged as unethical in settings in which patients could be treated with an existing therapy (1-7). The issues of when placebo controls are ethically acceptable and when they are scientifically necessary are important and worthy of discussion. The Ethics of Placebo Controls The Declaration of Helsinki The Declaration of Helsinki (8) is an international document that describes ethical principles for clinical investigation. Those who contend that placebo controls are unethical whenever known effective therapy exists for a condition usually cite the following sentence in the Declaration as support for that position: In any medical study, every patientincluding those of a control group, if anyshould be assured of the best proven diagnostic and therapeutic method. We believe that an interpretation of this sentence as barring placebo controls whenever an effective treatment exists is untenable. First, the requirement that all patients receive the best proven diagnostic and therapeutic method would bar not only placebo-controlled trials but also active-control and historically controlled trials. When effective treatment exists, the patient receiving the investigational treatment instead of the established therapy is clearly not getting the best proven treatment. Second, it does not seem reasonable to consider as equivalent all failures to use known effective therapy. Historically, concerns about placebo use have usually arisen in the context of serious illness. There is universal agreement that use of placebo or otherwise untreated controls is almost always unethical when therapy shown to improve survival or decrease serious morbidity is available. But in cases in which the treatment does not affect the patient's long-term health, an ethical imperative to use existing therapy is not plausible. Can it be, for example, that because topical minoxidil or oral finasteride can grow hair, a placebo-controlled trial of a new remedy for baldness is unethical? Is it really unethical to use placebos in short-term studies of drugs for allergic rhinitis, insomnia, anxiety, dermatoses, heartburn, or headaches in fully informed patients? We do not believe that there is a reasonable basis for arguing that such studies and many other placebo-controlled studies of symptom relief are unethical and that an informed patient cannot properly be asked to participate in them. Third, there is good reason to doubt that the cited phrase was intended to discourage placebo-controlled trials. The phrase under discussion was not part of the original 1964 Declaration but was added in 1975 to reinforce the idea that the physicianpatient relationship must be respected just as it would be in a purely therapeutic situation not involving research objectives (8). In the explanation accompanying the 1975 change, the issue of placebo-controlled trials was not even mentioned (9). The American Medical Association (10), the World Health Organization (11), and the Council for International Organizations of Medical Sciences (12) have rejected the position that the Declaration uniformly bars placebo-controlled trials when proven therapy is available. Informed Consent in Placebo-Controlled Trials Patients asked to participate in a placebo-controlled trial must be informed of the existence of any effective therapy, must be able to explore the consequences of deferring such therapy with the investigator, and must provide fully informed consent. Concern about whether consent to participate in trials is as informed as we would like to believe is valid, but these concerns apply as much to the patient's decision to forgo known effective treatment and risk exposure to a potentially ineffective or even harmful new agent in an active-control trial as to a decision to accept possible persistence of symptoms in a placebo-controlled trial. Thus, this problem is not unique to placebo-controlled trials. For the above reasons, we conclude that placebo-controlled trials may be ethically conducted even when effective therapy exists, as long as patients will not be harmed by participation and are fully informed about their alternatives. Although in many cases application of this standard will be fairly straightforward, in others it will not, and there may be debate about the consequences of deferring treatment (13). Assessment of Effectiveness with Active-Control Trials Clinical trials that, because of deficiencies in study design or conduct, are unlikely to provide scientifically valid and clinically meaningful results raise their own ethical concerns (12, 14). The remainder of this paper will address the inability of commonly proposed alternatives to placebo-controlled trials to evaluate the effectiveness of new treatments in many medical settings. Active-Control Equivalence Trials (Noninferiority Trials) The ability to conduct a placebo-controlled trial ethically in a given situation does not necessarily mean that placebo-controlled trials should be carried out when effective therapy exists. Patients and physicians might still prefer a trial in which every participant is given an active treatment. What remains to be examined is why placebo-controlled trials (or, more generally, trials intended to show an advantage of one treatment over another) are frequently needed to demonstrate the effectiveness of new treatments and often cannot be replaced by active-control trials showing that a new drug is equivalent or noninferior to a known effective agent. The limitations of active-control equivalence trials (ACETs) that are intended to show the effectiveness of a new drug have long been recognized and are well described (15-33) but are perhaps not as widely appreciated as they should be. A recent proposed international guideline on choice of control group addresses this issue in detail (33). The Fundamental Problem: Need for Assay Sensitivity There are two distinct ways to show that a new therapy is effective. One can show that the new therapy is superior to a control treatment, or one can show that the new therapy is equivalent to or not worse by some defined amount than a known effective treatment. Each method can be valid, but each requires entirely different inferential approaches. A well-designed study that shows superiority of a treatment to a control (placebo or active therapy) provides strong evidence of the effectiveness of the new treatment, limited only by the statistical uncertainty of the result. No information external to the trial is needed to support the conclusion of effectiveness. In contrast, a study that successfully shows equivalencethat is, little difference between a new drug and known active treatmentdoes not by itself demonstrate that the new treatment is effective. Equivalence could mean that the treatments were both effective in the study, but it could also mean that both treatments were ineffective in the study. To conclude from an ACET that a new treatment is effective on the basis of its similarity to the active control, one must make the critical (and untestable within the study) assumption that the active control had an effect in that particular study. In other words, one must assume that if a placebo group had been included, the placebo would have been inferior to the active control (15-33). Support for this assumption must come from sources external to the trial. Although it might appear reasonable to expect a known active agent to be superior to placebo in any given appropriately designed trial, experience has shown that this is not the case for many types of drugs. The ability of a study to distinguish between active and inactive treatments is termed assay sensitivity. If assay sensitivity cannot be assumed, then even if the new and standard treatments appear virtually identical and the confidence interval for their comparison is exquisitely narrow, the study cannot demonstrate effectiveness of the new drug. (Note that in practice, ACETs are not designed simply to show lack of a statistically significant difference between treatments. Rather, such trials are designed to show noninferioritythat the new treatment is not inferior to the control by more than a specified margin. This approach is described in the Appendix.) The best evidence that an active drug would have an effect superior to that of placebo in a given study would be a series of trials of similar design in which the active drug has reliably outperformed placebo. The ACET thus requires information external to the trial (the information about past placebo-controlled studies of the active control) to interpret the results. In this respect, an ACET is similar to a historically controlled trial. In some settings, such as highly responsive cancers, most infectious diseases, and some cardiovascular conditions, such external information is available and ACETs can and do provide a valid and reliable basis for evaluating new treatments. In many cases, however, the historically based assumption of assay sensitivity cannot be made; for many types of effective drugs, studies of apparently adequate size and design do not regularly distinguish drugs from placebo (16-18, 25, 34). More than 20 years ago, Lasagna (19) described this difficulty particularly well (reflecting long recognition of the problem among analgesiologists): a comparison between new drug and standard is convincing only when the new remedy is superior to standard treatment. If it is inferior, or even indistinguishable from a standard remedy, the results are not readily interpretable. In the absence of placebo controls, one does not know if the inferior new medicine has any efficacy at all, and equivalent performance may reflect simply a patient population that cannot distinguish between two active treatments that differ considerably from each other, or between active drug and placebo.

DESIGN Incremental cost effectiveness analysis of a randomised controlled trial. SETTING Medical wards in 14 hospitals in the United Kingdom. PARTICIPANTS The trial comprised 236 patients admitted to hospital with an acute exacerbation of chronic obstructive pulmonary disease and mild to moderate acidosis (pH 7.25-7.35) secondary to respiratory failure. The economic analysis compared the costs of treatment that these patients received after randomisation. MAIN OUTCOME MEASURE Incremental cost per in-hospital death. RESULTS 24/118 died in the group receiving standard treatment and 12/118 in the group receiving non-invasive ventilation (P=0.05). Allocation to the group receiving non-invasive ventilation was associated with a reduction in costs of 49362 pounds sterling (78741 dollars; 73109 euros), mainly through reduced use of intensive care units. The incremental cost effectiveness ratio was -645 pounds sterling per death avoided (95% confidence interval -2310 pounds sterling to 386 pounds sterling), indicating a dominant (more effective and less costly) strategy. Modelling of these data indicates that a typical UK hospital providing a non-invasive ventilation service will avoid six deaths and three to nine admissions to intensive care units per year, with an associated cost reduction of 12000-53000 pounds sterling per year.

DESIGN Decision analytical model comparing four prioritisation strategies without biomarkers (no formal prioritisation, two urgency scores, and a risk score) and three strategies based on a risk score using biomarkers: a routinely assessed biomarker (estimated glomerular filtration rate), a novel biomarker (C reactive protein), or both. The order in which to perform coronary artery bypass grafting in a cohort of patients was determined by each prioritisation strategy, and mean lifetime costs and quality adjusted life years (QALYs) were compared. DATA SOURCES Swedish Coronary Angiography and Angioplasty Registry (9935 patients with stable angina awaiting coronary artery bypass grafting and then followed up for cardiovascular events after the procedure for 3.8 years), and meta-analyses of prognostic effects (relative risks) of biomarkers. RESULTS The observed risk of cardiovascular events while on the waiting list for coronary artery bypass grafting was 3 per 10,000 patients per day within the first 90 days (184 events in 9935 patients). Using a cost effectiveness threshold of pound20,000- pound30,000 (euro22,000-euro33,000; $32,000-$48,000) per additional QALY, a prioritisation strategy using a risk score with estimated glomerular filtration rate was the most cost effective strategy (cost per additional QALY was < pound410 compared with the Ontario urgency score). The impact on population health of implementing this strategy was 800 QALYs per 100,000 patients at an additional cost of pound 245,000 to the National Health Service. The prioritisation strategy using a risk score with C reactive protein was associated with lower QALYs and higher costs compared with a risk score using estimated glomerular filtration rate. CONCLUSION Evaluating the cost effectiveness of prognostic biomarkers is important even when effects at an individual level are small. Formal prioritisation of patients awaiting coronary artery bypass grafting using a routinely assessed biomarker (estimated glomerular filtration rate) along with simple, routinely collected clinical information was cost effective. Prioritisation strategies based on the prognostic information conferred by C reactive protein, which is not currently measured in this context, or a combination of C reactive protein and estimated glomerular filtration rate, is unlikely to be cost effective.

Under the 90-90-90 scenario, 30.4 (95% CI 30.1, 30.7) million adults and 1.68 (95% CI 1.63, 1.73) million children could receive treatment by 2020. The facility-level financial resources needed for scaling up ART in these countries from 2015 to 2020 are estimated to be US$45.8 (95% CI 45.4, 46.2) billion under the current scenario, US$48.7 (95% CI 47.8, 49.6) billion under the WHO 2013 scenario, and US$52.5 (95% CI 51.4, 53.6) billion under the 90-90-90 scenario. After projecting recent external and domestic funding trends, the estimated 6-y financing gap ranges from US$19.8 billion to US$25.0 billion, depending on the costing scenario and the U.S. President's Emergency Plan for AIDS Relief contribution level, with the gap for ART commodities alone ranging from US$14.0 to US$16.8 billion. The study is limited by excluding above-facility and other costs essential to ART service delivery and by the availability and quality of country- and region-specific data. CONCLUSIONS The projected number of people receiving ART across three scenarios suggests that countries are unlikely to meet the 90-90-90 treatment target (81% of people living with HIV on ART by 2020) unless they adopt a test-and-offer approach and increase ART coverage. Our results suggest that future resource needs for ART scale-up are smaller than stated elsewhere but still significantly threaten the sustainability of the global HIV response without additional resource mobilization from domestic or innovative financing sources or efficiency gains.

Measurement of bone mass by densitometry is a primary part of diagnosing osteoporosis and deciding a preventive treatment course. Bone mineral densitometry has become more widely available and commonly used in practice. OBJECTIVE To review evidence about the value of various clinical applications of bone densitometry. DATA SOURCES A MEDLINE search was performed to update previous meta-analyses of the relationship between various measurements of bone density and risk of vertebral and hip fracture. We used data from the prospective Study of Osteoporotic Fractures to estimate risk of fracture from bone density and age in postmenopausal women. STUDY SELECTION AND DATA EXTRACTION When available, meta-analyses and systematic reviews are emphasized in the review. DATA SYNTHESIS Bone mineral density (BMD) predicts fracture and can be used in combination with age to estimate absolute risk of fractures in postmenopausal white women. Hip BMD predicts hip fracture more strongly than other measurements of BMD. There are insufficient data to translate BMD results into risk of fracture for men and nonwhite women. The benefits of treatments to prevent fractures depend on BMD: women with osteoporosis have a greater risk of fractures and greater benefit from treatments than women without osteoporosis. CONCLUSIONS Guidelines based on systematic reviews and a cost-effectiveness analysis have suggested that it is worthwhile to measure BMD in white women older than 65 years and perhaps to use risk factors to select younger postmenopausal women for densitometry. Other potential clinical applications of BMD that have not yet been adequately studied include screening men or nonwhite women, monitoring BMD in patients receiving treatment, and using BMD to identify patients who should be evaluated for secondary causes of osteoporosis.", "title": "Clinical use of bone densitometry: scientific review." }, { "docid": "1287809", "text": "IMPORTANCE The American College of Cardiology and the American Heart Association (ACC/AHA) cholesterol treatment guidelines have wide-scale implications for treating adults without history of atherosclerotic cardiovascular disease (ASCVD) with statins. OBJECTIVE To estimate the cost-effectiveness of various 10-year ASCVD risk thresholds that could be used in the ACC/AHA cholesterol treatment guidelines. DESIGN, SETTING, AND PARTICIPANTS Microsimulation model, including lifetime time horizon, US societal perspective, 3% discount rate for costs, and health outcomes. In the model, hypothetical individuals from a representative US population aged 40 to 75 years received statin treatment, experienced ASCVD events, and died from ASCVD-related or non-ASCVD-related causes based on ASCVD natural history and statin treatment parameters. Data sources for model parameters included National Health and Nutrition Examination Surveys, large clinical trials and meta-analyses for statin benefits and treatment, and other published sources. MAIN OUTCOMES AND MEASURES Estimated ASCVD events prevented and incremental costs per quality-adjusted life-year (QALY) gained. RESULTS In the base-case scenario, the current ASCVD threshold of 7.5% or higher, which was estimated to be associated with 48% of adults treated with statins, had an incremental cost-effectiveness ratio (ICER) of $37,000/QALY compared with a 10% or higher threshold. More lenient ASCVD thresholds of 4.0% or higher (61% of adults treated) and 3.0% or higher (67% of adults treated) had ICERs of $81,000/QALY and $140,000/QALY, respectively. Shifting from a 7.5% or higher ASCVD risk threshold to a 3.0% or higher ASCVD risk threshold was estimated to be associated with an additional 161,560 cardiovascular disease events averted. Cost-effectiveness results were sensitive to changes in the disutility associated with taking a pill daily, statin price, and the risk of statin-induced diabetes. In probabilistic sensitivity analysis, there was a higher than 93% chance that the optimal ASCVD threshold was 5.0% or lower using a cost-effectiveness threshold of $100,000/QALY. CONCLUSIONS AND RELEVANCE In this microsimulation model of US adults aged 45 to 75 years [corrected], the current 10-year ASCVD risk threshold (≥7.5% risk threshold) used in the ACC/AHA cholesterol treatment guidelines has an acceptable cost-effectiveness profile (ICER, $37,000/QALY), but more lenient ASCVD thresholds would be optimal using cost-effectiveness thresholds of $100,000/QALY (≥4.0% risk threshold) or $150,000/QALY (≥3.0% risk threshold).

Screening is opportunistic (annual/biannual) contributing to social and geographical disparities. METHODS A multi-HPV-type microsimulation model was calibrated to epidemiologic data from Spain utilising likelihood-based methods to assess the health and economic impact of adding HPV vaccination to cervical cancer screening. Strategies included (1) screening alone of women over age 25, varying frequency (every 1-5 years) and test (cytology, HPV DNA testing); (2) HPV vaccination of 11-year-old girls combined with screening. Outcomes included lifetime cancer risk, life expectancy, lifetime costs, number of clinical procedures and incremental cost-effectiveness ratios. RESULTS After the introduction of HPV vaccination, screening will need to continue, and strategies that incorporated HPV testing are more effective and cost-effective than those with cytology alone. For vaccinated girls, 5-year organised cytology with HPV testing as triage from ages 30 to 65 costs 24,350€ per year of life saved (YLS), assuming life-long vaccine immunity against HPV-16/18 by 3 doses with 90% coverage. Unvaccinated girls would benefit from organised cytology screening with HPV testing as triage; 5-year screening from ages 30 to 65 costs 16,060€/YLS and 4-year screening from ages 30 to 85 costs 38,250€/YLS. Interventions would be cost-effective depending on the cost-effectiveness threshold and the vaccine price. CONCLUSIONS In Spain, inequitable coverage and overuse of cytology make screening programmes inefficient. If high vaccination coverage among pre-adolescent girls is achieved, organised cytology screening with HPV triage starting at ages 30 to at least 65 every 4-5 years represents the best balance between costs and benefits.", "title": "Cost-effectiveness of human papillomavirus vaccination and screening in Spain." }, { "docid": "21203899", "text": "Kidney donor exchanges enable recipients with immunologically incompatible donors to receive compatible living donor grafts; however, the financial management of these exchanges, especially when an organ is shipped, is complex and thus has the potential to impede the broader implementation of donor exchange programs.

Field-based analyses of malaria transmission have frequently relied on the prevalence of asexual parasites or gametocytes as proxies for infectiousness. We now summarize empirical data on human infectiousness from Africa and Papua New Guinea. Over a wide range of transmission intensities there is little relationship between the infectiousness of human populations to vector mosquitoes and mosquito-to-human transmission intensity. We compare these data with the predictions of a stochastic simulation model of Plasmodium falciparum epidemiology. This model predicted little variation in the infectiousness of the human population for entomologic inoculation rates (EIRs) greater than approximately 10 infectious bites per year, demonstrating that the lack of relationship between the EIR and the infectious reservoir can be explained without invoking any effects of acquired transmission-blocking immunity. The near absence of field data from areas with an EIR < 10 per year precluded validation of the model predictions for low EIR values. These results suggest that interventions reducing mosquito-to-human transmission will have little or no effect on human infectiousness at the levels of transmission found in most rural areas of sub-Saharan Africa.

Based on the concept of lack of redundancy of social ties we defined clinical cut-points of the LSNS-6 for identifying persons deemed at risk for social isolation. RESULTS Among all three samples, the LSNS-6 and two subscales (Family and Friends) demonstrated high levels of internal consistency, stable factor structures, and high correlations with criterion variables. The proposed clinical cut-points showed good convergent validity, and classified 20% of the respondents in Hamburg, 11% of those in Solothurn (Switzerland), and 15% of those in London as at risk for social isolation.

SETTING Hlabisa health district, KwaZulu-Natal, South Africa. METHODS An economic analysis comparing the current tuberculosis management strategy in Hlabisa with three alternative strategies (the Hlabisa strategy prior to 1991 based on hospitalisation, the national strategy and sanatorium care) in terms of costs to both health service and patient and of cost-effectiveness. RESULTS The current Hlabisa strategy was the most cost-effective (R3799 per patient cured), compared with R98307 for the strategy used prior to 1991, R9940 for the national strategy, and R11145 for sanatorium care. Between 71% and 88% of treatment costs lie with the health service, and hospitalisation (R119 per day) is the most expensive item. Prolonged hospitalisation is extremely expensive, but community care is cheaper (community clinic visit, R28; community health worker visit, R7). The total cost of supervising a patient in the community under the current Hlabisa strategy was R503, equivalent to 4.2 days in hospital. Drug costs (R157) are equivalent to just 1.3 days in hospital.

We aimed to compare the cost-effectiveness of different diagnostic strategies for hypertension. METHODS We did a Markov model-based probabilistic cost-effectiveness analysis. We used a hypothetical primary-care population aged 40 years or older with a screening blood-pressure measurement greater than 140/90 mm Hg and risk-factor prevalence equivalent to the general population. We compared three diagnostic strategies-further blood pressure measurement in the clinic, at home, and with an ambulatory monitor-in terms of lifetime costs, quality-adjusted life years, and cost-effectiveness. FINDINGS Ambulatory monitoring was the most cost-effective strategy for the diagnosis of hypertension for men and women of all ages. It was cost-saving for all groups (from -£56 [95% CI -105 to -10] in men aged 75 years to -£323 [-389 to -222] in women aged 40 years) and resulted in more quality-adjusted life years for men and women older than 50 years (from 0·006 [0·000 to 0·015] for women aged 60 years to 0·022 [0·012 to 0·035] for men aged 70 years). This finding was robust when assessed with a wide range of deterministic sensitivity analyses around the base case, but was sensitive if home monitoring was judged to have equal test performance to ambulatory monitoring or if treatment was judged effective irrespective of whether an individual was hypertensive. INTERPRETATION Ambulatory monitoring as a diagnostic strategy for hypertension after an initial raised reading in the clinic would reduce misdiagnosis and save costs.

Industries involved in the production of high-value crops are most likely to benefit from desalinated water as they use more-efficient irrigation practices and have the highest gross value of irrigated agricultural production. Groundwater was identified as the most likely feedwater source for cost-effective desalination, which is also the case worldwide. Brine disposal is a major factor in overall cost effectiveness of desalination. When feedwater salinity is relatively low, mixing permeate with feedwater leads to an increase in water production and a reduction in water cost. It was estimated that Australian farmers are unlikely to pay more than AU$1.2/kL for agricultural water. Generally for agriculture, desalinated water is still more expensive than water from other sources; however, there are likely to be circumstances when the costs could be comparable.", "title": "Feasibility assessment of desalination application in Australian traditional agriculture" }, { "docid": "39984099", "text": "BACKGROUND New WHO guidelines recommend ART initiation for HIV-positive persons with CD4 cell counts ≤500 cells/µL, a higher threshold than was previously recommended.

METHODS We used multiple independent mathematical models in four settings-South Africa, Zambia, India, and Vietnam-to evaluate the potential health impact, costs, and cost-effectiveness of different adult ART eligibility criteria under scenarios of current and expanded treatment coverage, with results projected over 20 years. Analyses considered extending eligibility to include individuals with CD4 ≤500 cells/µL or all HIV-positive adults, compared to the previous recommendation of initiation with CD4 ≤350 cells/µL. We assessed costs from a health system perspective, and calculated the incremental cost per DALY averted ($/DALY) to compare competing strategies. Strategies were considered 'very cost-effective' if the $/DALY was less than the country's per capita gross domestic product (GDP; South Africa: $8040, Zambia: $1425, India: $1489, Vietnam: $1407) and 'cost-effective' if $/DALY was less than three times per capita GDP. FINDINGS In South Africa, the cost per DALY averted of extending ART eligibility to CD4 ≤500 cells/µL ranged from $237 to $1691/DALY compared to 2010 guidelines; in Zambia, expanded eligibility ranged from improving health outcomes while reducing costs (i.e. dominating current guidelines) to $749/DALY. Results were similar in scenarios with substantially expanded treatment access and for expanding eligibility to all HIV-positive adults. Expanding treatment coverage in the general population was therefore found to be cost-effective. In India, eligibility for all HIV-positive persons ranged from $131 to $241/DALY and in Vietnam eligibility for CD4 ≤500 cells/µL cost $290/DALY. In concentrated epidemics, expanded access among key populations was also cost-effective.

METHODS Decomposition of life expectancy by age and cause of death. Changes in life expectancy during transition by cause of death were examined using data for 1988/89 and 1990/91 for the former GDR and Poland; examination of life expectancy changes after transition were based on 1992-97 data for Germany and 1991-96 data for Poland. RESULTS In both the former GDR and Poland male life expectancy at birth declined by almost one year during transition, mainly attributable to rising death rates from external causes and circulatory diseases. Female life expectancy in Poland deteriorated by 0.3 years, largely attributable to increasing circulatory mortality among the old, while in East German female rising death rates in children and young adults were nearly outbalanced by declining circulatory mortality among those over 70. Between 1991/92 and 1996/97, male life expectancy at birth increased by 2.4 years in the former GDR, 1.2 years in old Federal Republic, and 2.0 years in Poland (women: 2.3, 0.9, and 1.2 years). In East Germany and Poland, the overall improvement was largely attributable to falling mortality among men aged 40-64, while those over 65 contributed the largest proportion to life expectancy gains in women. The change in deaths among men aged 15-39 accounted for 0.4 of a year to life expectancy at birth in East Germany and Poland, attributable largely to greater decreases from external causes. Among those over 40, absolute contributions to changing life expectancy were greater in the former GDR than in the other two entities in both sexes, largely attributable to circulatory diseases. A persisting East-west life expectancy gap in Germany of 2.1 years in men in 1997 was largely attributable to external causes, diseases of the digestive system and circulatory diseases. Higher death rates from circulatory diseases among the elderly largely explain the female life expectancy gap of approximately one year.

The use of these drugs for secondary prevention of CVD is well founded, but their expanding use in primary prevention—in individuals without documented CVD—has raised some concerns. Firstly, evidence suggests that, in primary prevention, statins substantially decrease CVD morbidity, but only moderately reduce CVD mortality. Secondly, long-term statin use might cause adverse effects, such as incident diabetes mellitus. Thirdly, the cost-effectiveness of such a strategy is unclear, and has to be balanced against the risk of 'overmedicating' the general population. Data clearly support the use of statins for primary prevention in high-risk individuals, in whom the strategy is cost-effective and the benefits exceed the risks.

A major disadvantage of this process is that the concentrate from the RO process, which could be as much as 25% of the feed stream, represents a polluting stream. This waste stream could pose a significant challenge to the implementation of this process, particularly for inland communities which do not have the option of ocean disposal.

The technologies evaluated in this study included bipolar membrane electrodialysis (BMED) for conversion of RO concentrate into mixed acid and mixed base streams, and electrochlorination (EC) for onsite chlorine generation. Bench-scale studies conducted with BMED demonstrated that RO concentrate could be desalted while producing mixed acids and mixed bases with concentrations as high as 0.2N. Similarly, the EC process was capable of producing a 0.6% hypochlorite solution from RO concentrate. The acids and bases as well as the hypochlorite produced could be directly applied to the RO process as well as upstream pre-treatment processes.

There was practically no misclassification in opposite extreme quartiles. De-attenuated energy-adjusted Pearson correlation coefficients between FFQ and S7 ranged from 0.22 for proteins and monounsaturated fatty acids to 0.80 for iron (mean: 0.45). 10% or less of subjects were misclassified in opposite extreme quartiles (except for vitamin C, 12%). Spearman correlation coefficients ranged from 0.25 for green-yellow-red raw vegetables to 0.76 for wine (mean: 0.42). 8% or less of subjects were misclassified in opposite extreme quartiles (except for citrus fruit, 11%).Conclusions: Portion estimation using the set of photographs was validated by the correlation between S4 and PETRA for both nutrients and foods. The FFQ provides a reasonably reliable measure of macronutrient intake and a good measure of micronutrient intake when compared with the data in the literature. It performs less well for food intake. Better results can be achieved for FFQ: (i) by using the set of photographs instead of standard portions and (ii) by adding further questions on foods which are insufficiently covered.

DESIGN A pre-post comparison was undertaken among the prospectively assessed cohorts of patients admitted to our medical intensive care unit 1 yr before and 1 yr after the change. Our data were stratified by Acute Physiology and Chronic Health Evaluation III quartile and whether a patient was admitted during the day or at night. Costs were modeled using a generalized linear model with log-link and γ-distributed errors. SETTING A large academic center in the Midwest. PATIENTS All patients admitted to the adult medical intensive care unit on or after January 1, 2005 and discharged on or before December 31, 2006. Patients receiving care under both staffing models were excluded. INTERVENTION Changing the intensive care unit staffing model from on-demand presence to mandatory 24-hr in-house critical care specialist presence. MEASUREMENTS AND MAIN RESULTS Total cost estimates of hospitalization were calculated for each patient starting from the day of intensive care unit admission to the day of hospital discharge. Adjusted mean total cost estimates were 61% lower in the post period relative to the pre period for patients admitted during night hours (7 pm to 7 am) who were in the highest Acute Physiology and Chronic Health Evaluation III quartile. No significant differences were seen at other severity levels. The unadjusted intensive care unit length of stay fell in the post period relative to the pre period (3.5 vs. 4.8) with no change in non-intensive care unit length of stay. CONCLUSIONS We find that 24-hr intensive care unit intensivist staffing reduces lengths of stay and cost estimates for the sickest patients admitted at night. The costs of introducing such a staffing model need to be weighed against the potential total savings generated for such patients in smaller intensive care units, especially ones that predominantly care for lower-acuity patients.", "title": "Economic implications of nighttime attending intensivist coverage in a medical intensive care unit." }, { "docid": "3690068", "text": "The standard treatment of partial-thickness burns includes topical silver products such as silver sulfadiazine (SSD) cream and enclosed dressings including silver-impregnated foam (Mepilex Ag; Molnlycke Health Care, Gothenburg, Sweden) and silver-laden sheets (Aquacel Ag; ConvaTec, Skillman, NJ). The current state of health care is limited by resources, with an emphasis on evidence-based outcomes and cost-effective treatments. This study includes a decision analysis with an incremental cost-utility ratio comparing enclosed silver dressings with SSD in partial-thickness burn patients with TBSA less than 20%. A comprehensive literature review was conducted to identify clinically relevant health states in partial-thickness burn patients. These health states include successful healing, infection, and noninfected delayed healing requiring either surgery or conservative management. The probabilities of these health states were combined with Medicare CPT reimbursement codes (cost) and patient-derived utilities to fit into the decision model. Utilities were obtained using a visual analog scale during patient interviews. Expected cost and quality-adjusted life years (QALYs) were calculated using the roll-back method. The incremental cost-utility ratio for enclosed silver dressing relative to SSD was $40,167.99/QALY. One-way sensitivity analysis of complication rates confirmed robustness of the model. Assuming a maximum willingness to pay $50,000/QALY, the complication rate for SSD must be 22% or higher for enclosed silver dressing to be cost effective.

Early detection of emerging areas of LD risk is critical to public health responses, but the methods to do so on a local scale are lacking. Passive tick surveillance has operated in Canada since 1990 but this method lacks specificity for identifying areas where tick populations are established because of dispersion of ticks from established LD risk areas by migratory birds. Using data from 70 field sites in Quebec visited previously, we developed a logistic regression model for estimating the risk of I. scapularis population establishment based on the number of ticks submitted in passive surveillance and a model-derived environmental suitability index. Sensitivity-specificity plots were used to select an optimal threshold value of the linear predictor from the model as the signal for tick population establishment. This value was used to produce an “Alert Map” identifying areas where the passive surveillance data suggested ticks were establishing in Quebec. Alert Map predictions were validated by field surveillance at 76 sites: the prevalence of established I. scapularis populations was significantly greater in areas predicted as high-risk by the Alert map (29 out of 48) than in areas predicted as moderate-risk (4 out of 30) (P < 0.001). This study suggests that Alert Maps created using this approach can provide a usefully rapid and accurate tool for early identification of emerging areas of LD risk at a geographic scale appropriate for local disease control and prevention activities.", "title": "Passive Surveillance for I. scapularis Ticks: Enhanced Analysis for Early Detection of Emerging Lyme Disease Risk" }, { "docid": "31844040", "text": "Two-component systems (TCSs) are widely employed by bacteria to sense specific external signals and conduct an appropriate response via a phosphorylation cascade within the cell.

However, estimates from claims data may lack clinical fidelity and can be affected by changing diagnosis and coding practices over time. Objective To estimate the US national incidence of sepsis and trends using detailed clinical data from the electronic health record (EHR) systems of diverse hospitals. Design, Setting, and Population Retrospective cohort study of adult patients admitted to 409 academic, community, and federal hospitals from 2009-2014. Exposures Sepsis was identified using clinical indicators of presumed infection and concurrent acute organ dysfunction, adapting Third International Consensus Definitions for Sepsis and Septic Shock (Sepsis-3) criteria for objective and consistent EHR-based surveillance. Main Outcomes and Measures Sepsis incidence, outcomes, and trends from 2009-2014 were calculated using regression models and compared with claims-based estimates using International Classification of Diseases, Ninth Revision, Clinical Modification codes for severe sepsis or septic shock. Case-finding criteria were validated against Sepsis-3 criteria using medical record reviews. Results A total of 173 690 sepsis cases (mean age, 66.5 [SD, 15.5] y; 77 660 [42.4%] women) were identified using clinical criteria among 2 901 019 adults admitted to study hospitals in 2014 (6.0% incidence). Of these, 26 061 (15.0%) died in the hospital and 10 731 (6.2%) were discharged to hospice. From 2009-2014, sepsis incidence using clinical criteria was stable (+0.6% relative change/y [95% CI, −2.3% to 3.5%], P = .67) whereas incidence per claims increased (+10.3%/y [95% CI, 7.2% to 13.3%], P < .001). In-hospital mortality using clinical criteria declined (−3.3%/y [95% CI, −5.6% to −1.0%], P = .004), but there was no significant change in the combined outcome of death or discharge to hospice (−1.3%/y [95% CI, −3.2% to 0.6%], P = .19). In contrast, mortality using claims declined significantly (−7.0%/y [95% CI, −8.8% to −5.2%], P < .001), as did death or discharge to hospice (−4.5%/y [95% CI, −6.1% to −2.8%], P < .001). Clinical criteria were more sensitive in identifying sepsis than claims (69.7% [95% CI, 52.9% to 92.0%] vs 32.3% [95% CI, 24.4% to 43.0%], P < .001), with comparable positive predictive value (70.4% [95% CI, 64.0% to 76.8%] vs 75.2% [95% CI, 69.8% to 80.6%], P = .23). Conclusions and Relevance In clinical data from 409 hospitals, sepsis was present in 6% of adult hospitalizations, and in contrast to claims-based analyses, neither the incidence of sepsis nor the combined outcome of death or discharge to hospice changed significantly between 2009-2014. The findings also suggest that EHR-based clinical data provide more objective estimates than claims-based data for sepsis surveillance.", "title": "Incidence and Trends of Sepsis in US Hospitals Using Clinical vs Claims Data, 2009-2014" } ]

There are many sources of information including books, websites such as http://investor.gov/investing-basics and this website. Don't skip the sections on taxes, as those matter just as much and sometimes more than the simple buying and selling. You might look at tax advantaged accounts, such as 401k's, IRA's, etc. It shouldn't take long but it will be one of the most important things you do as a beginning investor. Everyone has to start here.

I also graduated from a good school (Finance/Comp Sci) with a mediocre GPA and had difficulty securing a full time position in finance. My best advice is to network the shit out of alumni you can connect to through LinkedIn or your schools alumni network homepage. People are MUCH more open to talking than you would typically think. Like your friends said, getting into IBD as an analyst is ideal as it gives you a great line on your resume, shows you worked hard, and has amazing training. Now comes the really shitty part of this conversation, if you've already graduated college, it's next to impossible to get into a bulge bracket as an analyst. Your best bet in this case would be to try to get into a mid-cap or boutique IB and work your way from there. Again though, networking means 100x more than anything else. Now the good news, investment research is very different from investment banking. Yes, equity research is within an investment bank (sell-side and buy-side), but it is very different from investment banking (see Chinese Walls). It's easier to make the transition into research without formal recruiting than it is to get into IB directly. Couple things to keep in mind, KNOW THE DIFFERENCE BETWEEN SELL-SIDE AN BUY-SIDE. I'm not talking about just one buys stuff the other tries to get you to buy it. I'm talking about conflicts of interest on the sell-side, personalities, types of research, what your role entails, org structure, etc. SELL-SIDE IS EXTREMELY DIFFERENT THAN BUY-SIDE!! Buy-side is MUCH less flexible than sell-side in recruiting, also. Do you currently own stocks, trade, track stocks all day long, etc.? If the answer is no to any of those, buy-side is really really hard. They want people who live and breath investing, markets, news, companies, because that's what they do. Also, training is effectively non-existent on the buy-side due to the size of the shops (some can have $10b with 10 people including admins). Now lets talk sell-side. This is where I'd recommend you put your resources if you're really passionate about it. They tend to hire people without experience more often into entry-level jobs (b/c most are larger investment banks that use research to promote underwriting/investment business). Also, you need to have a pitch, but not as extensive as on the buy-side (those 1-2 pagers I talked about). The best advice I can offer is to hop on a Bloomberg/TR/CapIQ terminal if you can and just start finding email addresses of sell-side analysts (they publish them in their reports), and start writing the analysts directly expressing your interest in the business and your desire to talk with them. Be frank about where you are in your career, but show a true passion for research, and that you are \"\"hungry.\"\" Attach your resume and keep the email short, a few sentences with maybe some bullets about how you could help that company. Spend the time to personalize it to that person. Follow up with a phone call in 1-2 weeks. They will appreciate the candidness and you'll find them to be very receptive. Even if these analysts don't have a job available right there, if they like you, they will pass you on to someone who might. This is how networking works, that guy might not have a job, but someone is always hiring, and its a tight knit community. The other option is to work for any finance firm in some role for 3-5 years then go back to get an MBA. With an MBA from a top school you can basically transition into anything.

The first thing you need to do is decide which you're going to take. The first is the case of the standard investor saving money for retirement (or some other long-term goal). He already has a job. He's not really interested in another job. He doesn't want to spend thousands of hours doing research. He should buy mutual funds or similar instruments to build diversified holdings all over the world. He's going to have is money invested for years at a time. He won't earn spectacular amazing awesome returns, but he'll earn solid returns. There will be a few years when he loses money, but he'll recover it just by waiting. The second is the case of the day trader. He attempts to understand ultra-short-term movements in stock prices due to news, rumors, and other things which stem from quirks of the market and the people who trade in it. He buys a stock, and when it's up a fraction of a percent half an hour later, sells it. This is very risky, requires a lot of attention and a good amount of money to work with, and you can lose a lot of money too. The modern day-trader also needs to compete with the \"\"high-frequency trading\"\" desks of Wall Street firms, with super-optimized computer networks located a block away from the exchange so that they can make orders faster than the guy two blocks away. I don't recommend this approach at all. The third case is the guy who wants to beat the market. He's got long-term aspirations and vision, but he does a lot more research into individual companies, figures out which are worth buying and which are not, and invests accordingly. (This is how Warren Buffett made it big.) You can make it work, but it's like starting a business: it's a ton of work, requires a good amount of money to get going, and you still risk losing lots of it. The fourth case is the guy who mostly invests in broad market indexes like #1, but has a little money set aside for the stocks he's researched and likes enough to invest in like #3. He's not going to make money like Warren Buffett, but he may get a little bit of an edge on the rest of the market. If he doesn't, and ends up losing money there instead, the rest of his stocks are still chugging along. The last and stupidest way is to treat it all like magic, buying things without understanding them or a clear plan of what you're going to do with them. You risk losing all your money.

Reports come out all the time, sometimes even from very smart people with no motivation to lie, about expected earnings for this company, or for that industry. Whether those predictions come true is something you will only find out with time. What you are considering is using financial information available to you (and equally available to the public) to make investment choices. This is called 'fundamental analysis'; that is, the analysis of the fundamentals of a business and what it should be worth. It forms the basis of how many investment firms decide where to put their money. In a perfectly 'efficient' market, all information available to the public is immediately factored into the market price for that company's stock. ie: if a bank report states with absolute certainty (through leaked documents) that Coca-Cola is going to announce 10% revenue growth tomorrow, then everyone will immediately buy Coca-Cola stock today, and then tomorrow there would be no impact. Even if PwC is 100% accurate in its predictions, if the rest of the market agrees with them, then the price at the time of IPO would equal the future value of the cashflows, meaning there would be no gain unless results surpassed expectations. So what you are proposing is to take one sliver of the information available to the public (have you also read all publicly available reports on those businesses and their industries?), and using that to make a high risk investment. Are you going to do better than the investment firms that have teams of researchers and years of experience in the investment world? You can do quite well by picking individual stocks, but you can also lose a lot of money if you do it haphazardly. Be aware that there is risk in doing any type of investing. There is higher than average risk if you invest in equities ('the stock market'). There is higher risk still, if you pick individual stocks. There is yet even higher risk, if you pick small startup companies. There are some specific interesting side-elements with your proposal to purchase stock about to have an IPO - those are better dealt with in a separate question if you want more information; search this site for 'IPO' and you should find a good starting point. In short, the company about to go public will hire a firm of analysts who will try to calculate the best price the public will accept for an offering of shares. Stock often goes up after IPO, but not always. Sometimes the company doesn't even fill its full IPO order, adding a new type of risk to a potential investor, that the stock will drop on day 1.

If you read this article, and you see an ad in the paper the next day for a Honda Civic with 40k miles, should you buy it for $14k? The answer is not without more research. And even if you determine enough about cars to find one for $14k that you can reasonably sell for $15k, there's a whole world of mechanics out there who buy and sell cars for a living, and they have an edge both because they can repair the cars themselves to sell for more, and also because they have experience to spot low-offers faster than you. And if you pick a clunker (or a stock that doesn't perform even when everyone expected it would), then you could lose some serious money. As with buying and selling individual stocks, there is money to be made from car trading, but that money gets made by people who really know what they're doing.

If the score is so important to you, which I think is somewhat unwise, then use a credit card. With a 750 you should be able to get a pretty good rate, but assume it is 18%.

But the details make it different. Of course there are fee differences in how your broker will handle it, and also margin requirements for shorting. Somebody playing games with overlapping features of ownership, sales, and purchases, may have tax and reporting obligations for straddles, wash sales, and related issues. A straight sale is generally less complicated for tax reporting purposes, and a loss is more likely to be respected than someone playing games with sales and purchases.

You could buy stock with rights such as voting, engage in other behavior such as forwards, shorts, or options to negate your economic exposure to the stock, while maintaining the right to vote.

The Beach Boys had four number-one songs.
[ { "docid": "The_Beach_Boys", "text": "The Beach Boys are an American rock band formed in Hawthorne , California , in 1961 . The group 's original lineup consisted of brothers Brian , Dennis , and Carl Wilson ; their cousin Mike Love ; and their friend Al Jardine . Distinguished by their vocal harmonies and early surf songs , they are one of the most influential acts of the rock era . The group , led by their principal songwriter and producer Brian , pioneered novel approaches to popular music form and production , combining their affinities for jazz-based vocal groups , 1950s rock and roll , and black R&B to create their unique sound . He later arranged his compositions for studio orchestras and explored a variety of other styles , often incorporating classical or jazz elements and unconventional recording techniques in innovative ways . The Beach Boys began as a garage band managed by the Wilsons ' father Murry , with Brian 's increasingly sophisticated songwriting and recording abilities dominating their creative direction . Emerging at the vanguard of the `` California Sound '' , they performed original material that reflected a southern California youth culture of surfing , cars , and romance . After 1964 , they abandoned the surfing aesthetic for more personal lyrics and multi-layered sounds . In 1966 , the Pet Sounds album and `` Good Vibrations '' single vaulted the group to the top level of rock innovators and established the band as symbols of the nascent counterculture era . Following the dissolution of the group 's Smile project in 1967 , Brian gradually ceded production and songwriting duties to the rest of the band , reducing his input because of mental health and substance abuse issues . The group 's public image subsequently faltered , and despite efforts to continue their psychedelic/avant-garde ventures and reclaim their hippie audiences , they were dismissed as an embodiment of the values and outlooks shared by early 1960s white , suburban teenagers . The continued success of their greatest hits albums during the mid 1970s precipitated the band 's transition into an oldies act , a move that was denigrated by critics and many fans . Since the 1980s , much-publicized legal wrangling over royalties , songwriting credits and use of the band 's name transpired . Dennis drowned in 1983 and Carl died of lung cancer in 1998 . After Carl 's death , many live configurations of the band fronted by Mike Love and Bruce Johnston continued to tour into the 2000s while other members pursued solo projects . Even though Wilson and Jardine have not performed with Love and Johnston 's band since their one-off 2012 reunion tour , they remain a part of the Beach Boys ' corporation , Brother Records Inc. . The Beach Boys are one of the most critically acclaimed , commercially successful , and widely influential bands of all time . The group had over eighty songs chart worldwide , thirty-six of them US Top 40 hits ( the most by an American rock band ) , four reaching number-one on the Billboard Hot 100 chart . The Beach Boys have sold in excess of 100 million records worldwide , making them one of the world 's best-selling bands of all time and are listed at No. 12 on Rolling Stone magazine 's 2004 list of the `` 100 Greatest Artists of All Time '' .

If the typical investor requires a rate of return of 10% on this business, your company would be worth 100k. In investing terms, you would have a PE ratio of 10. The immediately-required return will be lower if substantially greater returns are expected in the future (expected growth), and the immediately required return will be higher if your business is expected to shrink. If at the end of the year you take your 10k and purchase another machine, your valuation will rise to 110k, because you can now produce 11k in earnings per year. If your business has issued 10,000 shares, your share price will rise from $10 to $11. Note that you did not just put cash in the bank, and that you now have a higher share price. At the end of year 2, with 11 machines, lets imagine that customer demand has fallen and you are forced to cut prices. You somehow produce only 10k in profit, instead of the anticipated 11k. Investors believe this 10k in annual profit will continue into the forseable future. The investor who requires 10% return would then only value your company at 100k, and your share price would fall back from $11 to $10. If your earnings had fallen even further to 9k, they might value you at 90k (9k/0.1=$90k). You still have the same machines, but the market has changed in a way that make those machines less valuable. If you've gone from earning 10k in year one with 10 machines to 9k in year two with 11 machines, an investor might assume you'll make even less in year three, potentially only 8k, so the value of your company might even fall to 80k or lower. Once it is assumed that your earnings will continue to shrink, an investor might value your business based on a higher required rate of return (e.g. maybe 20% instead of 10%), which would cause your share price to fall even further.", "title": "" }, { "docid": "253339", "text": "Aside from the market implications Victor and JB King mention, another possible reason is the dividends they pay. Usually, the dividends a company pays are dependent on the profit the company made. if a company makes less profit, the dividends turn out smaller.

Usually the expectation of a company's results are already priced into the share price, so if the results deviate from these expectations, the share price can move up or down respectfully. For example, many times a company's share price may be beaten down for increasing profits by 20% above the previous year when the expectation was that it would increase profits by 30%. Other times a company's share price may rise sharply for making a 20% loss when the expectation was that it would make a 30% loss. Then there is also a company's prospects for future growth and performance. A company may be heading into trouble, so even though they made a $100M profit this year, the outlook for the company may be bleak. This could cause the share price to drop accordingly. Conversely, a company may have made a loss of $100M but its is turning a corner after reducing costs and restructuring. This can be seen as a positive for the future causing the share price to rise. Also, a company making $100M in profits would not put that all into the bank.

If now they announce that their profits were only 750k$, then people may think that the 2M$ are more likely to be 1.5M$, so the company's value would go to ~ 5M$.

When profits drop, every investor has to re-think what the expected future profits of the company are. If all the investors say \"\"I thought this company would make a billion profit in the next ten years, but based on the drop in profits I changed my mind and I think they will only make 500 million\"\", then the share price drops. On the other hand, if profits dropped because of some predictable event, then that drop was already priced into the share price. If the profits dropped less than expected, the share price might even go up.

[ { "docid": "421371", "text": "\"It's been said before, but to repeat succinctly, a company's current share price is no more or less than what \"\"the market\"\" thinks that share is worth, as measured by the price at which the shares are being bought and sold. As such, a lot of things can affect that price, some of them material, others ethereal. A common reason to own stock is to share the profits of the company; by owning 1 share out of 1 million shares outstanding, you are entitled to 1/1000000 of that company's quarterly profits (if any). These are paid out as dividends. Two key measurements are based on these dividend payments; the first is \"\"earnings per share\"\", which is the company's stated quarterly profits, divided by outstanding shares, with the second being the \"\"price-earnings ratio\"\" which is the current price of the stock divided by its EPS. Your expected \"\"yield\"\" on this stock is more or less the inverse of this number; if a company has a P/E ratio of 20, then all things being equal, if you invest $100 in this stock you can expect a return of $5, or 5% (1/20). As such, changes in the expected earnings per share can cause the share price to rise or fall to maintain a P/E ratio that the pool of buyers are willing to tolerate. News that a company might miss its profit expectations, due to a decrease in consumer demand, an increase in raw materials costs, labor, financing, or any of a multitude of things that industry analysts watch, can cause the stock price to drop sharply as people look for better investments with higher yields. However, a large P/E ratio is not necessarily a bad thing, especially for a large stable company. That stability means the company is better able to weather economic problems, and thus it is a lower risk. Now, not all companies issue dividends. Apple is probably the most well-known example. The company simply retains all its earnings to reinvest in itself. This is typically the strategy of a smaller start-up; whether they're making good money or not, they typically want to keep what they make so they can keep growing, and the shareholders are usually fine with that. Why? Well, because there's more than one way to value a company, and more than one way to look at a stock. Owning one share of a stock can be seen quite literally as owning a share of that company. The share can then be valued as a fraction of the company's total assets. Sounds simple, but it isn't, because not every asset the company owns has a line in the financial statements. A company's brand name, for instance, has no tangible value, and yet it is probably the most valuable single thing Apple owns. Similarly, intellectual property doesn't have a \"\"book value\"\" on a company's balance sheet, but again, these are huge contributors to the success and profitability of a company like Apple; the company is viewed as a center of innovation, and if it were not doing any innovating, it would very quickly be seen as a middleman for some other company's ideas and products. A company can't sustain that position for long even if it's raking in the money in the meantime. Overall, the value of a company is generally a combination of these two things; by owning a portion of stock, you own a piece of the company's assets, and also claim a piece of their profits. A large company with a lot of material assets and very little debt can be highly valued based solely on the sum of its parts, even if profits are lagging.

The millions of share holders receive the same amount that you did as dividend, and of course, that money is not falling from the sky. The company pays it from their profits. So the day a dividend is announced, it is adjusted in the price of the share. The only reason why you look for dividend in a company is when you need liquidity.

You issue 5 shares worth Rs 100 each to the public and take Rs 100 for each share. Now you have Rs 1000 to start your company. 2.) You make a profit of Rs 200. 3.)

Since you owned 5 shares, you get 5*20 that is Rs.100 and you distribute the remaining to your 5 shareholders and expect to make the same or higher profit next year. Your share price remains at Rs.100 and you have your profits in cash. Case 2:- You think that this business is awesome and you should put more money into it to make more. You decide not to pay any dividend and invest the entire profit into the business. That way your shareholders do not receive anything from you but they get to share profit in the amazing business that you are doing. In this case your share price is Rs. 120 ((1000+200)/10) and all your profits are re-invested in the business. Now put yourself in the shareholders shoes and see which case suits you more.

Well, the corporate charter describes why the company exists. Usually the purpose is to enrich the shareholders. The owners of a company want to make money, in other words. There are a number of ways that a shareholder can make money off a stock: As such, maintaining the stock price and dividend payouts are generally the number one concern for any company in the long term. Most of the company's business is going to be directed towards making the company more valuable for a future buyout, or more valuable in terms of what it can pay its shareholders directly. Note that the company doesn't always need to be worried about the specifics of the day-to-day moves of the stock. If it keeps the finances in line - solid profits, margins, earnings growth and the like - and can credibly tell people that it's generally a valuable business, it can usually shrug off any medium-term blips as market craziness. Some companies are more explicitly long-term about things than others (e.g. Berkshire Hathaway basically tells people that it doesn't care all that much about what happens in the short term). Of course, companies are abstractions, and they're run by people. To make the people running the company worry about the stock price, you give them stock. Or stock options, or something like that. A major executive at a big company is likely to have a significant amount of stock. If the company does well, he does well; if it does poorly, he does poorly. Despite a few limitations, this is really a powerful incentive. If a company is losing a lot of money, or if its profits are falling so it's just losing a lot of its value as a business, the owners (stockholders) tend to get upset, and may vote in new management, or launch some sort of shareholder lawsuit. And, as previously noted, to raise funds, a company can also issue new shares to the market as a secondary offering as well (and they can issue fewer shares if the price is high - meaning that whatever the company is worth afterward, the existing owners own proportionally more of it).", "title": "" }, { "docid": "341652", "text": "\"No, the stock market is not there for speculation on corporate memorabilia.

If you knew that the business would have profit of $10,000,000 every year, and would distribute that to the owners of each of its 10,000,000 shares each year, you would know to that each share would receive $1 each year. How much would such a share be worth to you? If you could instead put money in a bank and get 5% a year back, to get $1 a year back you would have to put $20 into the bank. So maybe that share of stock is worth about $20 to you. If somebody offers to sell you such a share for $18, you might buy it; for $23, maybe you pass up the offer. But business is uncertain, and how much profit the business will make is uncertain and will vary through time. So how much is a share of a real business worth? This is a much harder call, and people use many different ways to come up with how much they should pay for a share. Some people probably just think something like \"\"Apple is a good company making money, I'll buy a share at whatever price it is being offered at right now.\"\" Others look at every number available, build models of the company and the economy and the risks, all to estimate what a share might be worth, more or less.

But how much more is not quantifiable but depends on each person's approach to the problem. Higher earnings would tend to raise the price of the stock. Yet there are other factors, such as people who had expected even higher earnings, whose actions would tend to lower the price, and people who are OK with the earnings now, but suspect trouble for the business is appearing on the horizon, whose actions would also tend to lower the price.

This can be due to forecasts that the company will start making profits in the near future.

This can cause its share price to fall, as the market is disappointed in the results. In the shorter term greed, fear and speculation can make a company's share price move irrationally. When you think the share price should be going up it suddenly falls, and Vis-versa. When interest rates are low, companies with higher dividend yields (compared to bank account interest rates) become high in demand and their shares generally go up in price. As the share price goes up the dividend yield will be reduced unless the company continues to increase the dividend it distributes to shareholders. When interest rates start to rise these companies become less favourable as they are seen as higher risk comparable to similar returns from having one's money in the safety of the bank.

A Simple Scenario: If Company A wants to open a new store, for example, they need to buy the land, build the store, stock it, etc, etc and this all costs money. The company can get a loan, use accrued capital, or raise new capital by issuing new stock. Each method has benefits and drawbacks. One of the drawbacks of issuing new stock is that it dilutes the existing stock's value. Previously, total company profits were split between x shares. Now the profits are shared between x+y shares, where y is the number of new shares issued to raise the capital. This normally drives the price of the stock down, since the expected future dividends per stock have decreased. Now the company has a problem: the next time they go to raise money by issuing stock, they will have to issue MORE shares to get the same value - leading to more dilution. To break out of this cycle, the company can buy back shares periodically. When the company feels the the stock is sufficiently undervalued, it buys some back. Now the profits are shared with a smaller pool, and the stock price goes up, and the next time Company A needs to raise capital, it can issue stock.

Here's why this is the case. Say we have A, who owns the stock and lends it to B, who then sells it short to C. After this the price drops and B buys the stock back from D and returns it to A. The outcome for A is neutral. Typically stock that is sold short must be held in a margin account; the broker can borrow the shares from A, collect interest from B, and A has no idea this is going on, because the shares are held in a street name (the brokerage's name) and not A. If A decides during this period to sell, the transaction will occur immediately, and the brokerage must shuffle things around so the shares can be delivered. If this is going to be difficult then the cost for borrowing shares becomes very high. The outcome for B is obviously a profit: they sold high first and bought (back) low afterwards. This leaves either C or D as having lost this money. Why isn't it D? One way of looking at this is that the profit to B comes from the difference in the price from selling to C and buying from D. D is sitting on the low end, and thus is not paying out the profit. D bought low, compared to C and this did not lose any money, so C is the only remaining choice. Another way of looking at it is that C actually \"\"lost\"\" all the money when purchasing the stock. After all, all the money went directly from C to B. In return, C got some stock with the hope that in the future C could sell it for more than was paid for it. But C literally gave the money to B, so how could anybody else \"\"pay\"\" the loss? Another way of looking at it is that C buys a stock which then decreases in value. C is thus now sitting on a loss. The fact that it is currently only a paper loss makes this less obvious; if the stock were to recover to the price C bought at, one might conclude that C did not lose the money to B. However, in this same scenario, D also makes money that C could have made had C bought at D's price, proving that C really did lose the money to B. The final way of seeing that the answer is C is to consider what happens when somebody sells a stock which they already hold but the price goes up; who did they lose out on the gain to?

It appears to be based on the assumption that the price of a stock is equal to the value of the assets of a company divided by the total number of shares. But that simply isn't true. You don't even need to do any in-depth analysis to prove it. Just look at share prices over a few days. You should easily be able to find stocks whose price varied wildly. If, say, a company becomes the target of a federal investigation, the share price will plummet the day the announcement is made. Did the company's assets really disappear that day? No. What's happened is that the company's long term prospects are now in doubt. Or a company announces a promising new product. The share price shoots up. They may not have sold a single unit of the new product yet, they haven't made a dollar. But their future prospects now look improved. Many factors go into determining a stock price. Sure, total assets is a factor. But more important is anticipated future earning. I think a very simple case could be made that if a stock never paid any dividends, and if everyone knew it would never pay any dividends, that stock is worthless. The stock will never produce any profit to the owner. So why should you be willing to pay anything for it? One could say, The value could go up and you could sell at a profit. But on what basis would the value go up? Why would investors be willing to pay larger and larger amounts of money for an asset that produces zero income? Update I think I understand the source of the confusion now, so let me add to my answer. Suppose that a company's stock is selling for, say, $10. And to simplify the discussion let's suppose that there is absolutely nothing affecting the value of that stock except an expected dividend. The company plans to pay a dividend on a specific date of $1 per share. This dividend is announced well in advance. Everyone knows that it will be paid, and everyone is extremely confidant that in fact the company really will pay it -- they won't run out of money or any such. Then in a pure market, we would expect that as the date of that dividend approaches, the price of the stock would rise until the day before the dividend is paid, it is $11. Then the day after the dividend is paid the price would fall back to $10. Why? Because the person who owns the stock on the \"\"dividend day\"\" will get that $1. So if you bought the stock the day before the dividend, the next day you would immediately receive $1. If without the dividend the stock is worth $10, then the day before the dividend the stock is worth $11 because you know that the next day you will get a $1 \"\"refund\"\". If you buy the stock the day after the dividend is paid, you will not get the $1 -- it will go to the person who had the stock yesterday -- so the value of the stock falls back to the \"\"normal\"\" $10. So if you look at the value of a stock immediately after a dividend is paid, yes, it will be less than it was the day before by an amount equal to the dividend. (Plus or minus all the other things that affect the value of a stock, which in many cases would totally mask this effect.) But this does not mean that the dividend is worthless. Just the opposite. The reason the stock price fell was precisely because the dividend has value. BUT IT ONLY HAS VALUE TO THE PERSON WHO GETS IT. It does me no good that YOU get a $1 dividend. I want ME to get the money. So if I buy the stock after the dividend was paid, I missed my chance. So sure, in the very short term, a stock loses value after paying a dividend. But this does not mean that dividends in general reduce the value of a stock. Just the opposite. The price fell because it had gone up in anticipation of the dividend and is now returning to the \"\"normal\"\" level. Without the dividend, the price would never have gone up in the first place. Imagine you had a company with negligible assets. For example, an accounting firm that rents office space so it doesn't own a building, its only tangible assets are some office supplies and the like. So if the company liquidates, it would be worth pretty much zero. Everybody knows that if liquidated, the company would be worth zero. Further suppose that everyone somehow knows that this company will never, ever again pay a dividend. (Maybe federal regulators are shutting the company down because it's products were declared unacceptably hazardous, or the company was built around one genius who just died, etc.) What is the stock worth? Zero. It is an investment that you KNOW has a zero return. Why would anyone be willing to pay anything for it? It's no answer to say that you might buy the stock in the hope that the price of the stock will go up and you can sell at a profit even with no dividends. Why would anyone else pay anything for this stock? Well, unless their stock certificates are pretty and people like to collect them or something like that. Otherwise you're supposing that people would knowingly buy into a pyramid scheme. (Of course in real life there are usually uncertainties. If a company is dying, some people may believe, rightly or wrongly, that there is still hope of reviving it. Etc.) Don't confuse the value of the assets of a company with the value of its stock. They are related, of course -- all else being equal, a company with a billion dollars in assets will have a higher market capitalization than a company with ten dollars in assets. But you can't calculate the price of a company's stock by adding up the value of all its assets, subtracting liabilities, and dividing by the number of shares. That's just not how it works.

Because when a company increases profits they are making more and more money which increases the net worth of the company. More investors would prefer to buy shares in a company that makes increasing profits because this will increase the net worth of the company, and in turn will drive the share price higher over the long term. A company's increase in profits creates higher demand for the company's shares.

These Daves I know are the kind of people that would like to own baseball cards over the long term just for their income-producing capability. Daves would seek out the cards with the best chance of producing and growing a reliable income stream. They wouldn't necessarily care about being able to flip a card at an inflated price to a Bob, but they might take advantage of inflated prices once in a while. Heck, even some of the Steves would enjoy this income while they waited for the eventual capital gain made by selling to a Bob at a higher price.

Daves would be willing to pay more for a card based on its income stream: how reliable it is, how high it is, how fast it grows, and where it is relative to market interest rates.

Addendum regarding your comment: I suppose I'm still struggling with the best way to present my question. I understand that companies differ in this aspect in that they produce value. But if stockholders cannot simply claim a percentage of a company's value equal to their share, then the fact that companies produce value seems irrelevant to the \"\"Bobs\"\". You're right – stockholders can't simply claim their percentage of a company's assets. Rather, shareholders vote in a board of directors. The board of directors can decide whether or not to issue dividends or buy back shares, each of which puts money back in your pocket. A board could even decide to dissolve the company and distribute the net assets (after paying debts and dissolution costs) to the shareholders – but this is seldom done because there's often more profit in remaining a going concern. I think perhaps what you are getting hung up on is the idea that a small shareholder can't command the company to give net assets in exchange for shares. Instead, generally speaking, a company runs somewhat like a democracy – but it's each share that gets a vote, not each shareholder. Since you can't redeem your shares back to the company on demand, there exists a secondary market – the stock market – where somebody else is willing to take over your investment based on what they perceive the value of your shares to be – and that market value is often different from the underlying \"\"book value\"\" per share.\"", "title": "" }, { "docid": "2748", "text": "from what i understand, which is not much, some companies use some of their own company shares as securitisation for loans.

The logic is that a bank who's stock price is low, or falling, is suffering from a decrease in their ability to tap the equity markets in times of need. With less ability to tap the equity markets in times of need, this means it is less likely the bank can raise funds to pay off debt, and thus, makes their debt more risky. It's unfair for me to imply a 100% causal relationship here, because that's not the case, but each of the markets interact with each other in some way. You will at least notice that, whether leading or trailing, companies that have a decreasing stock price also often have a decreasing credit rating. You'll also notice that stocks which slip under $5 often times get put on credit watch. The logic could go any which way around the circle, but a company that cuts its dividend may lose some investors who were in it for the dividend. This can cause stock price to fall. Credit agencies, depending on the situation, may approve of companies that cut their dividend (more cash to pay off debt), or, may indicate the dividend cut is not enough to make up for the company's falling profits. In the absence of full information, a cut in the dividend is often seen as a sign of weakness or a sign of tough times for the company in the future. Companies which have changes in dividend are looked at as less stable, more unpredictable, blah blah blah. Again, I'm not implying a 100% causal relationship here, but, each of these markets work with each other somehow, and a bank which cuts its dividend may be expecting lower profitability, slower growth, need the funds to cover lawsuit payouts or settlements with insert-regulatory-agency, or any number of other situations.", "title": "" }, { "docid": "386278", "text": "how do they turn shares into cash that they can then use to grow their business?

Why would a stock opening price differ from the offering price? From what I've read so far, it seems that pre-IPO an investment bank essentially buys the companies public shares, and that bank then sells them on the open market.

Typically, a hedge is an additional position that you would take on in order to mitigate the potential for losses on another position. I'll give an example: Say that I purchase 100 shares of stock XYZ at $10 per share because I believe its price will increase in the future. At that point, my full investment of $1000 is at risk, so the position is not hedged. If the price of XYZ decreases to $8, then I've lost $200. If the price of XYZ increases to $12, then I've gained $200; the profit/loss curve has a linear relationship to the future stock price. Suppose that I decide to hedge my XYZ position by purchasing a put option. I purchase a single option contract (corresponding to my 100 shares) with a strike price of $10 and an expiration date in January 2013 for a price of $0.50/share. This means that until the contract expires, I can always sell my XYZ shares for a minimum of $10. Therefore, if the price of XYZ decreases to $8, then I've only lost $50 (the price of the option contract), compared to the $200 that I would have lost if the position was unhedged. Likewise, however, if the price increases to $12, then I've only gained a net total of $150 due to the money I spent on the hedge. (the details of how much money you would actually lose in the hedged scenario are simplified out above; even out-of-the-money options retain some value before expiration, but pricing of options is outside of the scope of this post) So, as a more pointed answer to your question, I would say that the hedged/unhedged status of a position can be characterized by its potential for loss.

The number should always be compared to the share price, so for instance if the EPS is $1 and the share price is $10, the EPS is 10% of the share price.

The stock price may fluctuate, but if the company keeps on making money you will eventually do so too as investor. If the EPS is low it means that the market expects the earnings to rise in the future, either because the company has a low profit margin that can be vastly improved, or because the business is expected to grow. Especially the last case may be a risky investment as you will lose money if the company doesn't grow fast enough, even if it does make a healthy profit.

While investing in individual stocks can be very useful as a learning experience, my opinion is that concentrating an entire portfolio in a few companies' stock is a mistake for most investors, and especially for a novice for several reasons. After all, only a handful of professional investors have ever beaten the market over the long term by picking stocks, so is it really worth trying? If you could, I'd say go work on Wall Street and good luck to you. Diversification For many investors, diversification is an important reason to use an ETF or index fund. If they were to focus on a few sectors or companies, it is more likely that they would have a lop-sided risk profile and might be subject to a larger downside risk potential than the market as a whole, i.e. \"\"don't put all your eggs in one basket\"\". Diversification is important because of the nature of compound investing - if you take a significant hit, it will take you a long time to recover because all of your future gains are building off of a smaller base. This is one reason that younger investors often take a larger position in equities, as they have longer to recover from significant market declines. While it is very possible to build a balanced, diversified portfolio from individual stocks, this isn't something I'd recommend for a new investor and would require a substantial college-level understanding of investments, and in any case, this portfolio would have a more discrete efficient frontier than the market as a whole. Lower Volatility Picking individual stocks or sectors would could also significantly increase or decrease the overall volatility of the portfolio relative to the market, especially if the stocks are highly cyclical or correlated to the same market factors. So if they are buying tech stocks, they might see bigger upswings and downswings compared to the market as a whole, or see the opposite effect in the case of utilities. In other words, owning a basket of individual stocks may result in an unintended volatility/beta profile. Lower Trading Costs and Taxes Investors who buy individual stocks tend to trade more in an attempt to beat the market. After accounting for commission fees, transaction costs (bid/ask spread), and taxes, most individual investors get only a fraction of the market average return. One famous academic study finds that investors who trade more trail the stock market more. Trading also tends to incur higher taxes since short term gains (<1 year) are taxed at marginal income tax rates that are higher than long term capital gains. Investors tend to trade due to behavioral failures such as trying to time the market, being overconfident, speculating on stocks instead of long-term investing, following what everyone else is doing, and getting in and out of the market as a result of an emotional reaction to volatility (ie buying when stocks are high/rising and selling when they are low/falling). Investing in index funds can involve minimal fees and discourages behavior that causes investors to incur excessive trading costs. This can make a big difference over the long run as extra costs and taxes compound significantly over time. It's Hard to Beat the Market since Markets are Quite Efficient Another reason to use funds is that it is reasonable to assume that at any point in time, the market does a fairly good job of pricing securities based on all known information. In other words, if a given stock is trading at a low P/E relative to the market, the market as a whole has decided that there is good reason for this valuation. This idea is based on the assumption that there are already so many professional analysts and traders looking for arbitrage opportunities that few such opportunities exist, and where they do exist, persist for only a short time. If you accept this theory generally (obviously, the market is not perfect), there is very little in the way of insight on pricing that the average novice investor could provide given limited knowledge of the markets and only a few hours of research. It might be more likely that opportunities identified by the novice would reflect omissions of relevant information. Trying to make money in this way then becomes a bet that other informed, professional investors are wrong and you are right (options traders, for example). Prices are Unpredictable (Behave Like \"\"Random\"\" Walks) If you want to make money as a long-term investor/owner rather than a speculator/trader, than most of the future change in asset prices will be a result of future events and information that is not yet known. Since no one knows how the world will change or who will be tomorrow's winners or losers, much less in 30 years, this is sometimes referred to as a \"\"random walk.\"\" You can point to fundamental analysis and say \"\"X company has great free cash flow, so I will invest in them\"\", but ultimately, the problem with this type of analysis is that everyone else has already done it too. For example, Warren Buffett famously already knows the price at which he'd buy every company he's interested in buying. When everyone else can do the same analysis as you, the price already reflects the market's take on that public information (Efficent Market theory), and what is left is the unknown (I wouldn't use the term \"\"random\"\"). Overall, I think there is simply a very large potential for an individual investor to make a few mistakes with individual stocks over 20+ years that will really cost a lot, and I think most investors want a balance of risk and return versus the largest possible return, and don't have an interest in developing a professional knowledge of stocks. I think a better strategy for most investors is to share in the future profits of companies buy holding a well-diversified portfolio for the long term and to avoid making a large number of decisions about which stocks to own.\"", "title": "" }, { "docid": "469125", "text": "Leverage increase returns, but also risks, ie, the least you can pay, the greater the opportunity to profit, but also the greater the chance you will be underwater. Leverage is given by the value of your asset (the house) over the equity you put down. So, for example, if the house is worth 100k and you put down 20k, then the leverage is 5 (another way to look at it is to see that the leverage is the inverse of the margin - or percentage down payment - so 1/0.20 = 5). The return on your investment will be magnified by the amount of your leverage. Suppose the value of your house goes up by 10%. Had you paid your house in full, your return would be 10%, or 10k/100k. However, if you had borrowed 80 dollars and your leverage was 5, as above, a 10% increase in the value of your house means you made a profit of 10k on a 20k investment, a return of 50%, or 10k/20k*100. As I said, your return was magnified by the amount of your leverage, that is, 10% return on the asset times your leverage of 5 = 50%. This is because all the profit of the house price appreciation goes to you, as the value of your debt does not depend on the value of the house. What you borrowed from the bank remains the same, regardless of whether the price of the house changed. The problem is that the amplification mechanism also works in reverse. If the price of the house falls by 10%, it means now you only have 10k equity. If the price falls enough your equity is wiped out and you are underwater, giving you an incentive to default on your loan.

Yet from 2003 through 2012, Pfizer funneled an amount equal to 71% of its profits into buybacks, and an amount equal to 75% of its profits into dividends.

If the required margin increases within a certain percentage of your account balance, you will get a margin call. If you then don't deposit more funds or close losing trades out, the broker will close all your trades. Note: Your account balance is the remaining funds you have left to open new trades with. I always use stop loss orders with all my open trades, and because of this my broker reduces the amount of margin required on each trade. This allows me to have more open trades at the one time without increasing my funds. Effects of a Losing Trade on Margin Say I have an account balance of $2,000 and open a long trade in a share CFD of 1,000 CFDs with a share price of $10 and margin of 10%. The face value of the shares would be $10,000, but my initial margin would be $1,000 (10% of $10,000). If I don't place a stop loss and the price falls to $9, I would have lost $1,000 and my remaining margin would now be $900 (10% of $9,000). So I would have $100 balance remaining in my account. I would probably receive a margin call to deposit more funds in or close out my trade. If I don't respond the broker will close out my position before my balance gets to $0. If instead I placed a stop loss at say $9.50, my initial margin might be reduced to $500. As the price drops to $9.60 I would have lost $400 and my remaining margin would now only be $100, with my account balance at $1,500. When the price drops to $9.50 I will get stopped out, my trade will be closed and I would have lost $500, with my account balance still at $1,500. Effects of a Winning Trade on Margin Say I have the same account balance as before and open the same trade but this time the price moves up. If I don't place a stop loss and the price goes up to $11, I would have made a $1,000 profit and my remaining margin will now be $1,100 (10% of $11,000). So my account balance would now be $2,000 + $1,000 - $1,100 = $1,900. If I had placed a stop loss at say $9.50 again and the price moves up to $10.50, I would have made a profit of $500 and my margin would now be $1,000. My account balance would be $2,000 + $500 - $1,000 = $1,500. However, if after the price went up to $10.50 I also moved my stop loss up to $10, then I would have $500 profit and only $500 margin. So my balance in this case would be $2,000 + $500 - $500 = $2,000.

But if the market price of an ETF share deviates significantly from its NAV, the per-share market value of the securities in its portfolio, then an Authorized Participant can make an arbitrage profit by a transaction (creation or redemption) that pushes the market price toward NAV. Thus as long as the markets are operating and the APs don't vanish in a puff of smoke we can expect price will track NAV. That reduces your question to: why does NAV = market value of the holdings underlying a bond ETF share decrease when the market interest rate rises? Let's consider an example. I'll use US Treasuries because they have very active markets, are treated as risk-free (although that can be debated), and excluding special cases like TIPS and strips are almost perfectly fungible. And I use round numbers for convenience. Let's assume the current market interest rate is 2% and 'Spindoctor 10-year Treasury Fund' opens for business with $100m invested (via APs) in 10-year T-notes with 2% coupon at par and 1m shares issued that are worth $100 each. Now assume the interest rate goes up to 3% (this is an example NOT A PREDICTION); no one wants to pay par for a 2% bond when they can get 3% elsewhere, so its value goes down to about 0.9 of par (not exactly due to the way the arithmetic works but close enough) and Spindoctor shares similarly slide to $90. At this price an investor gets slightly over 2% (coupon*face/basis) plus approximately 1% amortized capital gain (slightly less due to time value) per year so it's competitive with a 3% coupon at par. As you say new bonds are available that pay 3%. But our fund doesn't hold them; we hold old bonds with a face value of $100m but a market value of only $90m. If we sell those bonds now and buy 3% bonds to (try to) replace them, we only get $90m par value of 3% bonds, so now our fund is paying a competitive 3% but NAV is still only $90. At the other extreme, say we hold the 2% bonds to maturity, paying out only 2% interest but letting our NAV increase as the remaining term (duration) and thus discount of the bonds decreases -- assuming the market interest rate doesn't change again, which for 10 years is probably unrealistic (ignoring 2009-2016!). At the end of 10 years the 2% bonds are redeemed at par and our NAV is back to $100 -- but from the investor's point of view they've forgone $10 in interest they could have received from an alternative investment over those 10 years, which is effectively an additional investment, so the original share price of $90 was correct.", "title": "" }, { "docid": "301547", "text": "\"To my knowledge, there's no universal equation, so this could vary by individual/company.

The reason for the bear market is that that's the time stocks generally go on \"\"sale\"\" and if a company has a solid balance sheet, even in a downturn, while their profit may decrease some, a value over 1.2 could indicate the company is oversold. An example of this is Warren Buffett's investment in Wells Fargo in 2009 (around March) when WFC hit approximately 7-9 a share. Although the banking world was experiencing a crisis, Buffett saw that WFC still had a solid balance sheet, even with a decrease in profit. The missing logic with many investors was a decrease in profits - if you look at the per capita income figures, Americans lost some income, but not near enough to justify the stock falling 50%+ from its high when evaluating its business and balance sheet. The market quickly caught this too - within two months, WFC was almost at $30 a share. As an interesting side note on this, WFC now pays $1.20 dividend a year. A person who bought it at $7 a share is receiving a yield of 17%+ on their $7 a share investment. Still, this equation is not without its risks. A company may have a solid balance sheet, but end up borrowing more money while losing a ton of profit, which the investor finds out about ad-hoc (seen this happen several times).

One final note: with robotraders becoming more common, I'm not sure we'll see this type of opportunity again. 2009 offered some great deals, but a robotrader could easily be built with the above equation (or a similar one), meaning that as soon as we had that type of environment, all stocks fitting that scenario would be bought, pushing up their PEs. Some companies might be willing to take an \"\"all risk\"\" if they assess that this equation works for more than n% of companies (especially if that n% returns an m% that outweighs the loss). The only advantage that a small investor might have is that these large companies with robotraders are over-leveraged in bad investments and with a decline, they can't make the good investments until its too late.

On each subsequent day, X goes up or down by 1 with probability 1/2. Let's think of buying a call option on X. A European option with a strike price of S that expires on day N, if held until that day and then exercised if profitable, would yield a value Y = min(X[N]-S, 0). This has an expected value E[Y] that you could actually calculate. (should be related to the binomial distribution, but my probability & statistics hat isn't working too well today) The market value V[k] of that option on day #k, where 1 < k < N, should be V[k] = E[Y]|X[k], which you can also actually calculate. On day #N, V[N] = Y. (the value is known) An American option, if held until day #k and then exercised if profitable, would yield a value Y[k] = min(X[k]-S, 0). For the moment, forget about selling the option on the market. (so, the choices are either exercise it on some day #k, or letting it expire) Let's say it's day k=N-1. If X[N-1] >= S+1 (in the money), then you have two choices: exercise today, or exercise tomorrow if profitable. The expected value is the same. (Both are equal to X[N-1]-S). So you might as well exercise it and make use of your money elsewhere. If X[N-1] <= S-1 (out of the money), the expected value is 0, whether you exercise today, when you know it's worthless, or if you wait until tomorrow, when the best case is if X[N-1]=S-1 and X[N] goes up to S, so the option is still worthless. But if X[N-1] = S (at the money), here's where it gets interesting. If you exercise today, it's worth 0. If wait until tomorrow, there's a 1/2 chance it's worth 0 (X[N]=S-1), and a 1/2 chance it's worth 1 (X[N]=S+1). Aha! So the expected value is 1/2. Therefore you should wait until tomorrow. Now let's say it's day k=N-2. Similar situation, but more choices: If X[N-2] >= S+2, you can either sell it today, in which case you know the value = X[N-2]-S, or you can wait until tomorrow, when the expected value is also X[N-2]-S. Again, you might as well exercise it now. If X[N-2] <= S-2, you know the option is worthless. If X[N-2] = S-1, it's worth 0 today, whereas if you wait until tomorrow, it's either worth an expected value of 1/2 if it goes up (X[N-1]=S), or 0 if it goes down, for a net expected value of 1/4, so you should wait. If X[N-2] = S, it's worth 0 today, whereas tomorrow it's either worth an expected value of 1 if it goes up, or 0 if it goes down -> net expected value of 1/2, so you should wait. If X[N-2] = S+1, it's worth 1 today, whereas tomorrow it's either worth an expected value of 2 if it goes up, or 1/2 if it goes down (X[N-1]=S) -> net expected value of 1.25, so you should wait. If it's day k=N-3, and X[N-3] >= S+3 then E[Y] = X[N-3]-S and you should exercise it now; or if X[N-3] <= S-3 then E[Y]=0. But if X[N-3] = S+2 then there's an expected value E[Y] of (3+1.25)/2 = 2.125 if you wait until tomorrow, vs. exercising it now with a value of 2; if X[N-3] = S+1 then E[Y] = (2+0.5)/2 = 1.25, vs. exercise value of 1; if X[N-3] = S then E[Y] = (1+0.5)/2 = 0.75 vs. exercise value of 0; if X[N-3] = S-1 then E[Y] = (0.5 + 0)/2 = 0.25, vs. exercise value of 0; if X[N-3] = S-2 then E[Y] = (0.25 + 0)/2 = 0.125, vs. exercise value of 0. (In all 5 cases, wait until tomorrow.) You can keep this up; the recursion formula is E[Y]|X[k]=S+d = {(E[Y]|X[k+1]=S+d+1)/2 + (E[Y]|X[k+1]=S+d-1) for N-k > d > -(N-k), when you should wait and see} or {0 for d <= -(N-k), when it doesn't matter and the option is worthless} or {d for d >= N-k, when you should exercise the option now}. The market value of the option on day #k should be the same as the expected value to someone who can either exercise it or wait. It should be possible to show that the expected value of an American option on X is greater than the expected value of a European option on X. The intuitive reason is that if the option is in the money by a large enough amount that it is not possible to be out of the money, the option should be exercised early (or sold), something a European option doesn't allow, whereas if it is nearly at the money, the option should be held, whereas if it is out of the money by a large enough amount that it is not possible to be in the money, the option is definitely worthless. As far as real securities go, they're not random walks (or at least, the probabilities are time-varying and more complex), but there should be analogous situations. And if there's ever a high probability a stock will go down, it's time to exercise/sell an in-the-money American option, whereas you can't do that with a European option. edit: ...what do you know: the computation I gave above for the random walk isn't too different conceptually from the Binomial options pricing model.", "title": "" }, { "docid": "523872", "text": "\"This is the best tl;dr I could make, [original](https://www.bloomberg.com/amp/view/articles/2017-09-21/bet-with-buffett-not-against-him) reduced by 90%.

There are two distinct pieces of the puzzle here. First, there's your organizational form. Your state, which is where the business is legally formed and recognized, creates the LLC or Corporation. \"\"S-Corp\"\" doesn't come into play here: your company is either an LLC or a Corporation. (There are a handful of other organizational types your state might have, e.g. PLLC, Limited Partnership, etc.; none of these are immediately relevant to this discussion). Second, there's the tax treatment you receive by the IRS. If your company was created by the state as an LLC, note that the IRS doesn't recognize LLCs as a distinct organizational type: you elect to be taxed as an individual (for single member LLCs), a partnership (for multiple member LLCs), or as a corporation. The former two elections are \"\"pass through\"\" -- there's no additional level of taxation on corporate profits, everything just passes through to the owners. The latter election introduces a tax on corporate profits. When you elect pass-through treatment, a single-member LLC files on Schedule C; a multiple-member LLC will prepare a form K-1 which you will include on your 1040. If your company was created by the state as a Corporation (not an LLC), you could still elect pass-through taxation if your company qualifies under the rules in Subchapter S (i.e. \"\"an S-Corp\"\"). States do not recognize \"\"S-Corp\"\" as part of the organizational process -- that's just a tax distinction used by the IRS (and possibly your state's tax authorities). In your case, if you are a single-member LLC (and assuming there are no other reasons to organize as a corporation), talking about \"\"S-Corp tax treatment\"\" doesn't make any sense. You'll just file your schedule C; in my experience it's fairly simple. (Note that this is based on my experience of single- and multiple-member LLCs in just two states. Your state may have different rules that affect state-level taxation; and the rules may change from year to year. I've found that hiring a good CPA to prepare the forms saves a good bit of stress and time that can be better applied to the business.)\"", "title": "" }, { "docid": "421455", "text": "\"The policy you quoted suggests you deposit 6% minimum. That $6,000 will cost you $4,500 due to the tax effect, yet after the match, you'll have $9,000 in the account. Taxable on withdrawal, but a great boost to the account. The question of where is less clear. There must be more than the 2 choices you mention. Most plans have 'too many' choices. This segues into my focus on expenses. A few years back, PBS Frontline aired a program titled The Retirement Gamble, in which fund expenses were discussed, with a focus on how an extra 1% in expenses will wipe out an extra 1/3 of your wealth in a 40 year period. Very simple to illustrate this - go to a calculator and enter .99 raised to the power of 40. .669 is the result. My 401(k) has an expense of .02% (that's 1/50 of 1%) .9998 raised to the same 40 gives .992, in other words, a cost of .8% over the full 40 years. My wife and I are just retired, and will have less in expenses for the rest of our lives than the average account cost for just 1 year. In your situation, the knee-jerk reaction is to tell you to maximize the 401(k) deposit at the current (2016) $18,000. That might be appropriate, but I'd suggest you look at the expense of the S&P index (sometime called Large Cap Fund, but see the prospectus) and if it's costing much more than .75%/yr, I'd go with an IRA (Roth, if you can't deduct the traditional IRA). Much of the value of the 401(k) beyond the match is the tax differential, i.e. depositing while in the 25% bracket, but withdrawing the funds at retirement, hopefully at 15%. It doesn't take long for the extra expense and the \"\"holy cow, my 401(k) just turned decades of dividends and long term cap gains into ordinary income\"\" effect to take over. Understand this now, not 30 years hence. Last - to answer your question, 'how much'? I often recommend what may seem a cliche \"\"continue to live like a student.\"\" Half the country lives on $54K or less. There's certainly a wide gray area, but in general, a person starting out will choose one of 2 paths, living just at, or even above his means, or living way below, and saving, say, 30-40% off the top. Even 30% doesn't hit the extreme saver level. If you do this, you'll find that if/when you get married, buy a house, have kids, etc. you'll still be able to save a reasonable percent of your income toward retirement. In response to your comment, what counts as retirement savings? There's a concept used as part of the budgeting process known as the envelope system. For those who have an income where there's little discretionary money left over each month, the method of putting money aside into small buckets is a great idea. In your case, say you take me up on the 30-40% challenge. 15% of it goes to a hard and fast retirement account. The rest, to savings, according to the general order of emergency fund, 6-12 months expenses, to cover a job loss, another fund for random expenses, such as new transmission (I've never needed one, but I hear they are expensive), and then the bucket towards house down payment. Keep in mind, I have no idea where you live or what a reasonable house would cost. Regardless, a 20-25% downpayment on even a $250K house is $60K. That will take some time to save up. If the housing in your area is more, bump it accordingly. If the savings starts to grow beyond any short term needs, it gets invested towards the long term, and is treated as \"\"retirement\"\" money. There is no such thing as Saving too much. When I turned 50 and was let go from a 30 year job, I wasn't unhappy that I saved too much and could call it quits that day.

An IPO is the way most companies get a public listing on the stock market. However, companies often go to market again and again to issue/sell more shares, after their IPO. These secondary offerings don't make as many headlines as an IPO, but they are typical-enough occurrences in markets. When a company goes back to the market to raise additional funds (perhaps to fund expansion), the value of the company's existing shares that are being traded is a good indicator of what they may expect to get for a secondary offering of shares. A company about to raise money desires a higher share price, because that will permit them to issue less shares for the amount of money they need. If the share price drops, they would need to issue more shares for the same amount of money – and dilute existing owners' share of the overall equity further. Also, consider corporate acquisitions: When one company wants to buy another, instead of the transaction being entirely in cash (maybe they don't have that much in the bank!), there's often an equity component, which involves swapping shares of the company being acquired for new shares in the acquiring company or merged company. In that case, the values of the shares in the public marketplace also matter, to provide relative valuations for the companies, etc.", "title": "" }, { "docid": "148270", "text": "The Art of Short Selling by Kathryn Stanley providers for many case studies about what kind of opportunities to look for from a fundamental analysis perspective. Typically things you can look for are financing terms that are not very favorable (expensive interest payments) as well as other constrictions on cash flow, arbitrary decisions by management (poor management), and dilution that doesn't make sense (usually another product of poor management). From a quantitative analysis perspective, you can gain insight by looking at the credit default swap rate history, if the company is listed in that market. The things that affect a CDS spread are different than what immediately affects share prices. Some market participants trade DOOMs over Credit Default Swaps, when they are betting on a company's insolvency. But looking at large trades in the options market isn't indicative of anything on its own, but you can use that information to help confirm your opinion. You can certainly jump on a trend using bad headlines, but typically by the time it is headline news, the majority of the downward move in the share price has already happened, or the stock opened lower because the news came outside of market hours. You have to factor in the short interest of the company, if the short interest is high then it will be very easy to squeeze the shorts resulting in a rally of share prices, the opposite of what you want. A short squeeze doesn't change the fundamental or quantitative reasons you wanted to short. The technical analysis should only be used to help you decide your entry and exit price ranges amongst an otherwise random walk.

Retirement accounts can contain nearly anything that one would consider an investment. (yes, there are exception, not the topic for today). So when one says they have an S&P fund or ETF, and some company issued Bonds, etc, these may or may not be held in a retirement account. In the US, when we say 'retirement account,' it means a bit more than just an account earmarked for that goal. It's an account, 401(k), 403(b), IRA, etc, that has a special tax status. Money can go in pre-tax, and be withdrawn at retirement when you are in a lower tax bracket. The Roth flavor of 401(k) or IRA lets you deposit post-tax money, and 'never' pay tax on it again, if withdrawn under specific conditions. In 2013, a single earner pays 25% federal tax on taxable earnings over $36K. But a retiree with exactly $46K in gross income (who then has $10K in standard deduction plus exemption) has a tax of $4950, less than 11% average rate on that withdrawal. This is the effect of the deductions, 10% and 15% brackets. As with your other question, there's a lot to be said about this topic, no one can answer in one post. That said, the second benefit of the retirement account is the mental partitioning. I have retirement money, not to be touched, emergency money used for the broken down car or appliance replacement, and other funds it doesn't feel bad to tap for spending, vacations, etc. Nothing a good spreadsheet can't handle, but a good way to keep things physically separate as well.

In all common sense the present value of a loan is the value that you can pay in the present to avoid taking a loan, which in this case is the lump sum payment of $2495. That rather supposes the question is a trick, providing irrelevant information about the stock market. However, if some strange interpretation is required which ignores the lump sum and wants to know how much you need in the present to pay the loan while being able to make 8% on the stock market that can be done. I will initially assume that since the lender's APR works out about 9.6% per month that the 8% from the stock market is also per month, but will also calculate for 8% annual effective and an 8% annual nominal rate. The calculation If you have $x in hand (present value) and it is exactly enough to take the loan while investing in the stock market, the value in successive months is $x plus the market return less the loan payment. In the third month the loan is paid down so the balance is zero. I.e. So the present value of using the payment plan while investing is $2569.37. You would need $2569.37 to cover the loan while investing, which is more than the $2495 lump sum payment requires. Therefore, it would be advisable to make the lump sum payment because it is less expensive: If you have $2569.37 in hand it would be best to pay the lump sum and invest the remaining $74.37 in the stock market. Otherwise you invest $2569.37 (initially), pay the loan and end up with $0 in three months. One might ask, what rate of return would the stock market need to yield to make it worth taking the loan? The APR proposed by the loan can be calculated. The present value of a loan is equal to the sum of the payments discounted to present value. I.e. with ∴ by induction So by comparing the $2495 lump sum payment with $997 over 3 x monthly instalments the interest rate implied by the loan can be found. Solving for r If you could obtain 9.64431% per month on the stock market the $x cash in hand required would be calculated by This is equal to the lump sum payment, so the calculated interest is comparable to the stock market rate of return. If you could gain more than 9.64431% per month on the stock market it would be better to invest and take the loan. Recurrence Form Solving the recurrence form shows the calculation is equivalent to the loan formula, e.g. becomes v[m + 1] = (1 + y) v[m] - p where v[0] = pv where In the final month v[final] = 0, i.e. when m = 3 Compare with the earlier loan formula: s = (d - d (1 + r)^-n) / r They are exactly equivalent, which is quite interesting, (because it wasn't immediately obvious to me that what the lender charges is the mirror opposite of what you gain by investing). The present value can be now be calculated using the formula. Still assuming the 8% stock market return is per month. If the stock market yield is 8% per annum effective rate and if it is given as a nominal annual yield, 8% compounded monthly", "title": "" }, { "docid": "521489", "text": "\"If you have an S-Corp with several shareholders - you probably also have a tax adviser who suggested using S-Corp to begin with. You're probably best off asking that adviser about this issue. If you decided to use S-Corp for multiple shareholders without a professional guiding you, you should probably start looking for such a professional, or you may get yourself into trouble. That said, and reminding you that: 1. Free advice on the Internet is worth exactly what you paid for it, and 2. I'm not a tax professional or tax adviser, you should talk to a EA/CPA licensed in your state, here's this: Generally S-Corps are disregarded entities for tax purposes and their income flows to their shareholders individual tax returns through K-1 forms distributed by the S-Corp yearly. The shareholders don't have to actually withdraw the profits, but if not withdrawing - they're added to their cost bases in the shares. I'm guessing your corp doesn't distribute the net income, but keeps it on the corporate account, only distributing enough to cover the shareholders' taxes on their respective income portion. In this case - the amount not distributed is added to their basis, the amount distributed has already been taxed through K-1. If the corporation distributes more than the shareholder's portion of net income, then there can be several different choices, depending on the circumstances: The extra distribution will be treated as salary to the shareholder and a deduction to the corporation (i.e.: increasing the net income for the rest of the shareholders). The extra distribution will be treated as return of investment, reducing that shareholder's basis in the shares, but not affecting the other shareholders. If the basis is 0 then it is treated as income to the shareholder and taxed at ordinary rates. The extra distribution will be treated as \"\"buy-back\"\" - reducing that shareholder's ownership stake in the company and reallocating the \"\"bought-back\"\" portion among the rest of the shareholders. In this case it is treated as a sale of stock, and the gain is calculated as with any other stock sale, including short-term vs. long-term taxation (there's also Sec. 1244 that can come in handy here). The extra distribution will be treated as dividend. This is very rare for S-Corp, but can happen if it was a C-Corp before. In that case it will be taxed as dividends. Note that options #2, #3 and #4 subject the shareholder to the NIIT, while option #1 subjects the shareholder to FICA/Self Employment tax (and subjects the company to payroll taxes).

None of the distribution is given special treatment as Qualified Dividends or Capital Gains regardless of what happened inside the IRA, and none of the distribution is subject to the 3.8% Net Investment Income Tax that some high-income people need to compute on Form 8960. If the withdrawal is not a Qualified Distribution, it will be subject to a 10% excise tax (tax penalty on premature withdrawal). Not all contributions to Traditional IRAs are deductible from income for the year for which the contribution was made. People with high income and/or coverage by a workplace retirement plan (pension plan, 401(k) plan, 403(b) plan, etc) cannot deduct any contributions that they choose to make to a Traditional IRA. Such people can always make a contribution (subject to them having compensation (earned income such as salary or wages, self-employment income, commissions on sales, etc), but they don't get a tax deduction for it (just as contributions to Roth IRAs are not deductible). Whether it is wise to make such nondeductible contributions to a Traditional IRA is a question on which reasonable people can hold different opinions. Be that as it may, nondeductible contributions to a Traditional IRA create (or add to) what is called the basis of an IRA. They are reported to the IRS on Form 8606 which is attached to the Federal Form 1040. Note that the IRA custodian or trustee is not told that the contributions are not deductible. Earnings on the basis accumulate tax-deferred within the IRA just as do the earnings on the deductible contributions. Now, when you make a withdrawal from your Traditional IRA, no matter which of your various IRA accounts you take the money from, part of the money is deemed to be taken from the basis (and is not subject to income tax) while the rest is pure taxable income. That is, none of the rest is eligible for the reduced taxation rates for Qualified Dividends or Capital Gains and since it does not count as investment income, it is not subject to the 3.8% Net Investment Tax of Form 8960 either. Computation of how much of your withdrawal is nontaxable basis and how much is taxable income is done on Form 8606. Note that you don't get to withdraw your entire basis until such time as when you close all your Traditional IRA accounts. How is all this reported? Well, your IRA custodian(s) will send you Form 1099-R reporting the total amount of the withdrawal, what income tax, if any, was withheld, etc. The custodian(s) don't know what your basis is, and so Box 2b will say that the taxable amount is not determined. You need to fill out Form 8606 to figure out what the taxable amount is, and then report the taxable amount on Line 15b of Form 1040. (The total withdrawal is reported on Line 15a which is not included in the AGI computations). Note that as far as the IRS is concerned, you have only one Traditional IRA. The A in IRA stands for Arrangement, not Account as most everybody thinks, and your Traditional IRA can invest in many different things, stocks, bonds, mutual funds, etc with different custodians if you choose, but your basis is in the IRA, not the specific investment that you made with your nondeductible contribution. That's why the total IRA contribution is limited, not the per-account contribution, and why you need to look that the total value of your IRA in determining the taxable portion, not the specific account(s) from which you withdrew the money. So, how much basis did you withdraw? Well, if you withdrew $W during 2016 and the total value of all your Traditional IRA accounts was $X at the end of 2016 and your total basis in your Traditional IRA is $B, then (assuming that you did not indulge in any Traditional-to-Roth rollovers for 2016), multiply W by B/(W+X) to get the amount of nontaxable basis in the withdrawal. B thus gets reduced for 2017 by amount of basis withdrawal. What if you never made a nondeductible contribution to your Traditional IRA, or you made some nondeductible contributions many years ago and have forgotten about them? Well, you could still fill out Form 8606 reporting a zero basis, but it will just tell you that your basis continues $0. Or, you could just enter the total amount of your withdrawal in Lines 15a and 15b, effectively saying that all of the withdrawal is taxable income to you. The IRS does not care if you choose to pay taxes on nontaxable income.", "title": "" } ]

Activation of PPM1D enhances p53 function.
[ { "docid": "4414547", "text": "Improved sequencing technologies offer unprecedented opportunities for investigating the role of rare genetic variation in common disease. However, there are considerable challenges with respect to study design, data analysis and replication. Using pooled next-generation sequencing of 507 genes implicated in the repair of DNA in 1,150 samples, an analytical strategy focused on protein-truncating variants (PTVs) and a large-scale sequencing case–control replication experiment in 13,642 individuals, here we show that rare PTVs in the p53-inducible protein phosphatase PPM1D are associated with predisposition to breast cancer and ovarian cancer. PPM1D PTV mutations were present in 25 out of 7,781 cases versus 1 out of 5,861 controls (P = 1.12 × 10−5), including 18 mutations in 6,912 individuals with breast cancer (P = 2.42 × 10−4) and 12 mutations in 1,121 individuals with ovarian cancer (P = 3.10 × 10−9). Notably, all of the identified PPM1D PTVs were mosaic in lymphocyte DNA and clustered within a 370-base-pair region in the final exon of the gene, carboxy-terminal to the phosphatase catalytic domain. Functional studies demonstrate that the mutations result in enhanced suppression of p53 in response to ionizing radiation exposure, suggesting that the mutant alleles encode hyperactive PPM1D isoforms. Thus, although the mutations cause premature protein truncation, they do not result in the simple loss-of-function effect typically associated with this class of variant, but instead probably have a gain-of-function effect. Our results have implications for the detection and management of breast and ovarian cancer risk. More generally, these data provide new insights into the role of rare and of mosaic genetic variants in common conditions, and the use of sequencing in their identification.", "title": "Mosaic PPM1D mutations are associated with predisposition to breast and ovarian cancer" }, { "docid": "5956380", "text": "Gliomas arising in the brainstem and thalamus are devastating tumors that are difficult to surgically resect.

Since p53 mutations are the most frequently reported genetic defects in human cancers, it becomes important to study the effects of mutations of p53 on promoter functions.

HeLa cells were cotransfected with a wild-type or mutant p53 expression vector and a plasmid containing a chloramphenicol acetyltransferase reporter gene under viral (or cellular) promoter control. As expected, expression of the wild-type p53 inhibited promoter function. Expression of a p53 with a mutation at any one of the four amino acid positions 175, 248, 273, or 281, however, correlated with a significant increase of the PCNA promoter activity (2- to 11-fold). The viral promoters were also activated, although to a somewhat lesser extent. We also showed that activation by a mutant p53 requires a minimal promoter containing a lone TATA box. A more significant increase (25-fold) in activation occurs when the promoter contains a binding site for the activating transcription factor or cyclic AMP response element-binding protein. Using Saos-2 cells that do not express p53, we showed that activation by a mutant p53 was a direct enhancement. The mutant forms of p53 used in this study are found in various cancer cells. The activation of PCNA by mutant p53s may indicate a way to increase cell proliferation by the mutant p53s.

In this study, we show that HER-2/neu-mediated resistance to DNA-damaging agents requires the activation of Akt, which enhances MDM2-mediated ubiquitination and degradation of p53. Akt physically associates with MDM2 and phosphorylates it at Ser166 and Ser186. Phosphorylation of MDM2 enhances its nuclear localization and its interaction with p300, and inhibits its interaction with p19ARF, thus increasing p53 degradation.

Interestingly, many of these regions possess conserved p53-binding sites and all known hallmarks of enhancer regions. We demonstrate that these p53-bound enhancer regions (p53BERs) indeed contain enhancer activity and interact intrachromosomally with multiple neighboring genes to convey long-distance p53-dependent transcription regulation. Furthermore, p53BERs produce, in a p53-dependent manner, enhancer RNAs (eRNAs) that are required for efficient transcriptional enhancement of interacting target genes and induction of a p53-dependent cell-cycle arrest. Thus, our results ascribe transcription enhancement activity to p53 with the capacity to regulate multiple genes from a single genomic binding site.

These reductions were attributable to enhanced apoptosis of NPCs and newborn neurons and were rescued by inhibition of caspase activity, p53, or the p53 apoptotic effector PUMA (p53-upregulated modulator of apoptosis). Moreover, these cellular deficits were functionally important because they led to perturbations in hippocampus-dependent memory formation.

Inhibition of p53 led to autophagy in enucleated cells, and cytoplasmic, not nuclear, p53 was able to repress the enhanced autophagy of p53−/− cells. Many different inducers of autophagy (for example, starvation, rapamycin and toxins affecting the endoplasmic reticulum) stimulated proteasome-mediated degradation of p53 through a pathway relying on the E3 ubiquitin ligase HDM2.

Loss of p53 in cardiac fibroblasts severely decreases the formation of fibroblast-derived endothelial cells, reduces post-infarct vascular density and worsens cardiac function.

The p53 248W mutant reduces abilities of both to bind HJ and inhibit helicase activities, whereas the p53 273H mutant loses these abilities. Moreover, full-length p53 and a C-terminal polypeptide (residues 373-383) inhibit the BLM and WRN helicase activities, but phosphorylation at Ser(376) or Ser(378) completely abolishes this inhibition. Following blockage of DNA replication, Ser(15) phospho-p53, BLM, and RAD51 colocalize in nuclear foci at sites likely to contain DNA replication intermediates in cells. Our results are consistent with a novel mechanism for p53-mediated regulation of DNA recombinational repair that involves p53 post-translational modifications and functional protein-protein interactions with BLM and WRN DNA helicases.", "title": "The processing of Holliday junctions by BLM and WRN helicases is regulated by p53." }, { "docid": "25901598", "text": "Posttranslational modifications mediate important regulatory functions in biology.

Previous studies have indicated that activation of p53 is caused by the inhibition of mouse double minute 2 (Mdm2), the main negative regulator of p53, by the 5S ribonucleoprotein particle (RNP). Meanwhile, it is not clear whether this mechanism solely mediates the p53-dependent component found in DBA.

Upon induction of the Rps19 deficiency, Mdm2C305F reversed the p53 response and improved expansion of hematopoietic progenitors in vitro, and ameliorated the anemia in vivo.

Accumulating evidence suggests that both p73 and p63 play important roles in regulation of apoptosis, cell differentiation, and therapeutic drug sensitivity. METHODS Gastric epithelial cells were cocultured with Helicobacter pylori, and the roles of p63 and p73 proteins were assessed by luciferase reporter, real-time polymerase chain reaction, immunoblotting, and cell survival assays. Short hairpin RNA and dominant-negative mutants were used to inhibit activity of p73 and p63 isoforms. Human and murine gastric tissues were analyzed by immunohistochemistry with p73 and p63 antibodies and modified Steiner's silver method. RESULTS Interaction of H pylori with gastric epithelial cells leads to robust up-regulation of p73 protein in vitro and in vivo in human gastritis specimens and H pylori-infected mice. The p73 increase resulted in up-regulation of pro-apoptotic genes, NOXA, PUMA, and FAS receptor in gastric epithelial cells. Down-regulation of p73 activity suppressed cell death and Fas receptor induced by H pylori. Bacterial virulence factors within the cag pathogenicity island, c-Abl tyrosine kinase, and interaction with p63 isoforms control the activity of p73.

Live cell imaging showed that MDMX depletion triggered two distinct phases of p53 accumulation in single cells: an initial postmitotic pulse, followed by low-amplitude oscillations. The response to DNA damage was sharply different in these two phases; in the first phase, MDMX depletion was synergistic with DNA damage in causing cell death, whereas in the second phase, depletion of MDMX inhibited cell death.

Several forms of DNA damage have been shown to activate p53, including those generated by ionising radiation (IR), radio-mimetic drugs, ultraviolet light (UV) and chemicals such as methyl methane sulfonate (MMS). Under normal conditions, p53 levels are maintained at a low state by virtue of the extremely short-half life of the polypeptide. In addition to this, p53 normally exists in an largely inactive state that is relatively inefficient at binding to DNA and activating transcription. Activation of p53 in response to DNA damage is associated with a rapid increase in its levels and with an increased ability of p53 to bind DNA and mediate transcriptional activation. This then leads to the activation of a number of genes whose products trigger cell-cycle arrest, apoptosis, or DNA repair. Recent work has suggested that this regulation is brought about largely through DNA damage triggering a series of phosphorylation, de-phosphorylation and acetylation events on the p53 polypeptide.

That may be in the form of loans or, better, grants in which you just get free money to attend college. For example, a Pell grant. You won't get all you'd need for a free ride this way, but you can really make a dent in what you'd pay. The college may likely also provide financial aid to you. In order to get any of this, though, you have to fill out a FAFSA. There are deadlines for this for each state and each college (there you would ask individually). I'd get looking into that as soon as you can. Do student loans have to be paid monthly? Any loan is a specific agreement between a lender and a borrower, so any payment terms could apply, such as bimonthly or quarterly. But monthly seems like the most reasonable assumption. Generally, you should assume the least favorable (reasonably likely) terms for you, so that you are prepared for a worst-case scenario. Let's say monthly. Can I just, as I had hoped, borrow large sums of money and only start paying them after college? Yes. That is a fair summary of all a student loan is. Importantly, though, some loans are federal government subsidized loans for which the interest on the loan is paid for you as long as you stay in college + 6 months (although do check that is the current situation). Unsubsidized loans may accrue interest from the start of the loan period. If you have the option, obviously try hard to get the subsidized loans as the interest can be significant. I made a point to only take subsidized loans. WARNING: Student loans currently enjoy a (nearly?) unique status in America as being one of the only loan types that are not forgivable in bankruptcy. This means that if you leave college with $100,000 in debt that begins accruing interest, there is no way for you to get out of it short of fleeing the country or existence. And at that point the creditors may come after your mother for the balance. These loans can balloon into outrageous amounts due to compounding interest. Please have a healthy fear of student loans. For more on this, listen to this hour long radio program about this. Would a minimum wage job help, Of course it will \"\"help\"\" but will it \"\"help enough\"\"? That depends on how much you work. If you make $7.50/hr and work 20 hrs/week for all but 3 weeks of the year, after taxes you will be adding about $6,000 to offset your costs. In 3 years of college (*see below), that's $18,000, which, depending on where you go, is not bad at helping defray costs. If you are at full-time (40 hrs), then it is $12k/yr or $36k toward defraying costs. These numbers are nothing to sniff at. Do you have any computer/web/graphics skills? It's possible you could find ways to make more than minimum wage if you learn some niche IT industry skill. (If I could go back and re-do those years I wouldn't have wasted much time delivering pizzas and would have learned HTML in the 90s and would have potentially made some significant money.) would college and full-time job be manageable together? That's highly specific to each situation (which job? how far a commute to it? which major? how efficient are you? how easily do you learn?) but I would say that, for the most part, it's not a good idea, not only for the academic-achievement side of it, but the personal-enrichment aspect of college. Clubs, sports, relationships, activities, dorm bull sessions, all that good stuff, they deserve their space and time and it'd be a shame to miss out on that because you're on the 2nd shift at Wal-Mart 40hrs/week. How do I find out what scholarships, grants, and financial aid I can apply for? Are you in a high school with a career or guidance counselor? If so, go to that person about this as a start.

There are also a lot of resources online found by just searching Google for scholarships--though do be careful about any online sources (including this advice!). Sermon: Lastly, please carefully consider the overall cost vs. benefit to you. College in 2012 is anything but cheap. A typical price for a textbook is $150 or more. Tuition and board can range over $40k at private colleges. There is a recent growing call for Americans to re-think the automatic nature of going to college considering the enormous financial burden it puts many families under. Charles Murray, for one, has put out a book suggesting that far too many students go to college now, to society's and many individuals' detriment (he's a controversial thinker, but I think some of his points are valid and actually urgent). With all that said, consider ways to go to college but keep costs down. Public colleges in your state will almost always be significantly cheaper than private or out-of-state.

Freedom comes from not being in debt (first) and having money (second). Why do you think Harvard grads are the guys that end up having so much money and power? It's probably because they grew up in a rich family which provided them money (freedom) and a wide social circle of rich people (connections). So you're not rich. What to do? Well, the easiest way to get into that group is to go to college with them. And that means you need to get into Harvard or another Ivy League. Stanford if you want to be an engineer.

You'll live a comfortable life and pay off your student loans in five or 10 years. Then you'll continue to live comfortably, but at that point you'll be too old to take huge chances and too comfortable to change things (or perhaps you'll have a big mortgage = no freedom).

It can be done, and it's really not too hard, you just have to have lots of spending restraint because the little money you have has to go a long way. So what are the other options? Well, some people are recommending that you think about not going to college at all. That will certainly save you money and give you a four year head start on whatever you decide to do (freedom), but you'll forever be branded as that guy without a college degree.

Well, you could go to community college. They're certainly cheap. You can spend very little money so you'll end up with fairly good freedom. I might add, though, that community colleges teach trades, and not high-level things like management and complex architecture. You'll be behind technically, but not as bad as if you didn't go at all. How about connections? Your fellow students will probably lack ambition, money, and connections. They'll be candidates for entry-level wage slave jobs at Fortune 500 companies after they graduate. If they get lucky, they'll work up to middle management. There's no alumni association, and there's certainly no \"\"DeVry Club\"\" in downtown Boston. At New York and Silicon Valley dinner parties, having a community college degree is almost as bad as having nothing at all. Indeed, the entire value of the community college degree will be what you learn, and you'll be learning at the speed and level of your classmates. My advice? If you get into an Ivy League school, go and hope you get some grants to help you out. The debt will suck, but you'll be well positioned for the future. Otherwise, go to a cheap second-tier school where you can get a large scholarship. There are also lots of third-party scholarships that are out there on the Internet you can get. I got a couple from local organizations. Don't work during college. Focus on expanding your network instead; the future value of a minimum wage job while you're trying to go through school is practically zero.\"", "title": "" } ]
[ { "docid": "70668", "text": "\"I will answer the question from the back: who can NOT afford luxury cars? Those whose parents paid for their college education, cannot afford luxury cars, but buy them anyway. Why? I have what may seem a rather shocking proposition related to the point of not saving for kids' college: parents do NOT owe children a college education. Why should they? Did your parents fund your college? Or did you get it through a mix of Pell grants, loans, and work? If they did, then you owe them $ back for it, adjusted for inflation. If they did not, well then why do you feel your children deserve more than you deserved when you were a child? You do not owe your children a college education. They owe it to themselves. Gifts do not set one up for success, they set one up for dependence. I will add one more hypothesis: financial discipline is best learned through one's own experiences. When an 18+ year old adult gets a very large amount of money as a gift every year for several years (in the form of paid tuition), does that teach them frugality and responsibility? My proposition is that those who get a free ride on their parents' backs are not well served in terms of becoming disciplined budgeters. They become the subjects of the question in this post: those why buy cars and houses they cannot afford, and pay for vacations with credit cards. We reap what we sow as a society. Of course, college is only one case in point, but a very illustrative one. The bigger point is that financial discipline can only be developed when there are opportunities to develop it. Such opportunities arise under one important condition: financial independence. What does buying children cars for their high-school graduation, buying them 4 years of college tuition, and buying them who knows what else (study abroad trips, airfare, apartment leases, textbooks, etc. etc.) teach? Does it teach independence or dependence? It can certainly (at least that's what you hope for) teach them to appreciate when others do super nice things for them. But does free money instill financial responsibility? Try to ask kids whose parents paid for their college WHY they did it. \"\"Because my parents want me to succeed\"\" is probably the best you can hope for. Now ask them, But do your parents OWE you a college education? \"\"Why yes, I guess they do.\"\" Why? \"\"Well, I guess because they told me they do. They said they owe it to me to set me up for success in life.\"\" Now think about this: Do people who become financially successful achieve that success because someone owed something to them? Or because they recognized that nobody owes them anything, and took it upon themselves to create that success for themselves? These are not very comfortable topics to consider, especially for those of you who have either already sunk many tens of thousands of dollars into your childrens' college education. Or for those who have been living very frugally and mindfully for the past 10-15 years driven by the goal of doing so. But I want to open this can of worms because I believe fundamentally it may be creating more problems than it is solving. I am sure there are some historical and cultural explanations for the ASSUMPTION that has at some point formed in the American society that parents owe their children a college education. But as with most social conventions, it is merely an idea -- a shared belief. It has become so ingrained in conversations at work parties and family reunions that it seems that many of those who are ardent advocates of the idea of paying for their childrens' education no longer even understand why they feel that way. They simply go with the flow of social expectations, unwilling or unable to question either the premises behind these expectations, or the long-term consequences and results of such expectations. With this comment I want to point to the connection between the free financial gifts that parents give to their (adult!) children, and the level of financial discipline of these young adults, their spending habits, sense of entitlement, and sense of responsibility over their financial decisions. The statistics of the U.S. savings rate, average credit card debt, foreclosures, and bankruptcy indeed tell a troubling story. My point is that these trends don't just happen because of lots of TV advertising and the proverbial Jones's. These trends happen because of a lack of financial education, discipline, and experience with balancing one's own checkbook. Perhaps we need to think more deeply about the consequences of our socially motivated decisions as parents, and what is really in our children's best interests -- not while they are in college, but while they live the rest of their lives after college. Finally, to all the 18+ y.o. adult 'children' who are reeling from the traumatic experience of not having their parents pay for their college (while some of their friends parents TOTALLY did!), I have this perspective to offer: Like you are now, your parents are adults. Their money is theirs to spend, because it was theirs to earn. You are under no obligation to pay for your parents' retirement (not that you were going to). Similarly your parents have no obligation to pay for your college. They can spend their money on absolutely whatever they want: be it a likeside cottage, vacations, a Corvette, or slots in the casino. How they spend their money is their concern only, and has nothing to do with your adult needs (such as college education). If your parents mismanage their finances and go bankrupt, it is their obligation to get themselves back in the black -- not yours. If you have the means and may be so inclined, you may help them; if you do not or are not, fair enough. Regardless of what you do, they will still love you as their child no less. Similarly, if your parents have the means and are so inclined, they may help you; if they do not or are not, fair enough. Regardless of what they do, you are to love them as your parents no less. Your task as an adult is to focus on how you will meet your own financial needs, not to dwell on which of your needs were not met by people whose finances should well be completely separate from yours at this point in life. For an adult, to harbor an expectation of receiving something of value for free is misguided: it betrays unjustified, illusory entitlement. It is the expectation of someone who is clueless as to the value of money measured by the effort and time needed to earn it. When adults want to acquire stuff or services, they have to pay for these things with their own money. That's how adults live. When adults want to get a massage or take a ride in a cab, are they traumatized by their parents' unfulfilled obligation to pay for these services? No -- they realize that it's their own responsibility to take care of these needs. They either need to earn the money to pay for these things, or buy them on credit and pay off the debt later. Education is a type of service, just like a massage or a cab ride. It is a service that you decide you need to get, in order to do xyz (become smarter, get a better paying job, join a profession, etc.). Therefore as with any other service, the primary responsibility for paying for this service is yours. You have 3 options (or their combination): work now so that you can earn the money to pay for this service later; work part-time while you are receiving this service; acquire the service on credit and work later to pay it off. That's it. This is called the real world. The better you can deal with it, the more successful you will become in it.

People go to college as a prerequisite for a career, but instead encounter a culture of learning for learning's sake, a system originally designed to turn independently wealthy gentlemen into erudite gentlemen.

This is my take on the picture, I'm not sure about your tax situation and how much you'd have to pay for each conversion you did, whether you have extra money to pay those taxes, etc. In my opinion I don't think it would be a good idea to use your 401(k) principal to pay taxes, but to have the extra money to pay these when rolling over so you don't lose any interest, especially since you're near the \"\"end\"\" of your \"\"snowball\"\" effect with interest in your retirement account. Here is a resource to consider. Also, another thing to consider that I don't really see much of on here is inflation. If you're going to be in the same tax bracket as you are now, and if whatever you're contributing to your 401(k) or traditional IRA is NOT bumping you down in the 15% bracket, then I would suggest doing a ROTH IRA. I say this because to me, when I retire, I would have rather paid my taxes throughout the years (I'm 23 and in 25% marginal tax bracket) in a ROTH IRA and pay nothing when I'm withdrawing in 30 years, factors people forget to consider are that the Cost of Living is going to be MUCH MUCH higher for me down the road, and the cost of sending a child to school is going to be much higher as well. Since your child is young, consider this site for the cost of a college education for your child. This is comparing the average cost of education for someone attending college in 2015 versus 2033 (a child born IN 2015).

While the website provided certainly isn't validated by the DoE, I have read multiple articles about this, and they are all very similar.

These often net a higher rate of return annually than any savings account, are not going to tank if the market does, and can be owned by you for the child. If no one else is on the policy, they have no access to it. You can name yourself the beneficiary as well. There's several very nice features to doing your child's college funding this way. You can ask that the contract is established for maximum cash value. This means the death benefit isn't the overriding need so the premiums you pay fill the cash value of the contract much more quickly. As mentioned in point 1., the contract has a death benefit. No other savings device will grant you this. Heaven forbid the child passes while you are saving for college. Now you will have a tax free benefit that will pay for burial and other related costs and can be used to fund yet another IUL policy if you have more than one child. Unlike other policies, you can set your minimum monthly premium and have the flexibility to add as much as you would like to fill the fund faster if you happen to come into more money and you want to direct it to that contract. There are ceilings to this so that you don't create a modified endowment contract (MEC. Look this up at investopedia), but this is specifically stated in your illustration so that you can keep your contributions a penny under that limit. Unlike college loans, you have extremely quick access to the funds when you need them (probably counter-intuitive to your desire for untouchable money). This can be achieved a couple of ways. You can borrow money from the insurer using your IUL cash value as collateral. Often, a check can be cut within 48 hours. This eliminates the time a normal lender takes in making the loan decision. Or, you can surrender the policy and take the cash value (paying taxes on your gains). The first keeps the policy in force while you pay back the loan if you desire. The second cancels the policy so that you can take your own accumulated money out. Utilizing an IUL in this manner can (but not always) lower your Expected Family Contribution (EFC) with colleges so that you could qualify for higher student aid. If your income puts you in the middle class, you would be wise to note this in particular. Having control over your EFC is major benefit.

Ultimately, while the IUL is a little known method for saving for college (and some will argue what they may) it would benefit you to speak with an insurance professional about this option. Ask if the insurer has access to the SAGE Rewards program (https://secure.tuitionrewards.com/). The program is a free benefit if you purchase a cash value contract like an Indexed Universal Life policy and activates IF the agency participates.

Twenty years later, that same education cost $6,500 per semester. The main difference between these periods is that borrowing for school is now standard practice (much less so in the 90s).

To be accepted to college was an accomplishment, to survive the first year was an accomplishment, and not to mention to graduate with a bachelor degree. The few who managed to accomplished that were accomplished men and women who got full benefits of their accomplishments, guaranteed!!!! Today, also as a former adjunct professor in college, I can tell you you that anyone graduates from high school (\"\"no student left behind\"\"), everyone(!), many barely know how to read, write or even tackle a simple logical question. And same in college: I was told I can't fail my students except in extreme cases. So what do we have here? You said it correct and clearly: &gt;Everybody having a college degree drives the value down for everybody...which is exactly what is happening. Further! It's just an industry to make money, put people into debt, give them almost worthless pieces of papers, force them to also study for a master's degree and reduce the pay for qualified people with degrees. Even Harvard! You would think that for $80,000/year tuition, you get good education. Instead, you are put in a auditorium with 500 other students for lectures. &gt; Things need to be turned on their head. Yes! You got it here too! &gt; I propose that Colleges need to receive their income as a percentage of the first 10-15 years of income from their students. Disagree! I propose to make the requirements for finish high school and college degrees much much higher, as it was in the past. As you said, too many people have [worthless] degrees!!!! The few who get degree, are accomplished people and will reap the benefits, including their employers. This is also the best formula for people to come out of poverty and low social-economic family background. Right now, if you are smart but from a poor background, oh yes, you get a degree, but it's worthless and won't help you much. But if the requirements are high, and you are smart, you are all set! As for people who fail high school and don't get degrees, they will not be spoiled as today's kids with all their degrees! Someone needs to be a plumber, electrician, trade or a clerk. And these jobs make very good many, much better than bank tellers with a bachelor degree.

One is, how quickly can you get cash out of your investments? If you had an unexpected expense, if you suddenly needed more cash than you have on hand, how long would it take to get money out of your Scott Trade account or wherever it is? I have a TD Ameritrade account which is pretty similar, and it just takes a couple of days to get money out. I'm hard pressed to think of a time when I literally needed a bunch of cash TODAY with no advance warning. What sudden bills is one likely to have? A medical bill, perhaps. But hey, just a few weeks ago I had to go to the emergency room with a medical problem, and it's not like they demanded cash on the table before they'd help me. I just got the bill, maybe 3 weeks after the event. I've never decided to move and then actually moved 2 days later. These things take SOME planning. Etc. Second, how much risk are you willing to tolerate? If you have your money in the stock market, the market could go down just as you need the cash. That's not even a worst case scenario, extreme scenario. After all, if the economy gets bad, the stock market could go down, and the same fact could result in your employer laying you off. That said, you could reduce this risk by keeping some of your money in a low-risk investment, like some high-quality bonds. Third, you want to have cash to cover the more modest, routine expenses. Like make sure you always have enough cash on hand to pay the rent or mortgage, buy food, and so on. And fourth, you want to keep a cushion against bookkeeping mistakes. I've had twice in my life that I've overdrawn a checking account, not because I was broke, but because I messed up my records and thought I had more money in the account than I really did. It's impossible to give exact numbers without knowing a lot about your income and expenses. But for myself: I keep a cushion of $1,000 to $1,5000 in my checking account, on top of all regular bills that I know I'll have to pay in the next month, to cover modest unexpected expenses and mistakes. I pay most of my bills by credit card for convenience --and pay the balance in full when I get the bill so I don't pay interest -- so I don't need a lot of cushion. I used to keep 2 to 3 months pay in an account invested in bonds and very safe stocks, something that wouldn't lose much value even in bad times. Since my daughter started college I've run this down to less than 1 months pay, and instead of replacing that money I'm instead putting my spare money into more general stocks, which is admittedly riskier. So between the two accounts I have a little over 2 months pay, which I think is low, but as I say, I'm trying to get my kids through college so I've run down my savings some. I think if I had more than 6 months pay in easily-liquidated assets, then unless I expected to need a bunch of cash for something, buying a new house or some such, I'd be transferring that to a retirement account with tax advantages.", "title": "" }, { "docid": "193296", "text": "Microsoft doesn't do salary negotiations...

Joe provides a nice taxonomy of loans. I would just add that some loans are not only guaranteed, but also subsidized. Essentially the Government buys down the rate of the loan. The mechanics are that a financial aid package might consist of grants, work study (job), subsidized, and guaranteed loans. One can turn down one or more of the elements of the package. All will be limited in some form. The work study will have a maximum number of hours and generally has low pay. Many find better deals working in the businesses surrounding the college or starting their own services type business. The grants rarely cover the full cost of tuition and books. The loans will both be limited in amount. It mainly depends on what you qualify for, and generally speaking the lower the income the more aid one qualifies for. Now some students use all their grant, all their loan money and buy things that are not necessary. For example are you going to live in the $450/month dorm, or the new fancy apartments that are running $800/month? Are you going to use the student loan money to buy a car? Will it be a new BMW or a 8 year old Camary? I see this first hand as I live near a large university. The pubs are filled with college students, not working, but drinking and eating every night. Many of them drive very fancy cars. The most onerous example of this is students at the military academies. Attendees have their books and tuition completely paid for. They also receive a stipend, and more money can be earned over the summer. They also all qualify for a 35K student loan in their junior year. Just about every kid, takes this loan. Most of those use the money to buy a car. I know a young lady who did exactly that, and so did many of her friends. So kids with a starting pay of 45K also start life with a 35K. Buying a nice car in the military is especially silly as they cannot drive it while deployed and they are very likely to be deployed. At least, however, they are guaranteed a starting job with a nice starting pay, and upward potential. College kids who behave similarly might not have it as good. Will they even find work? Will the job have the ability to move up? How much security is in the job?

Diseases did not also spread along the Silk Road.
[ { "docid": "Silk_Road", "text": "The Silk Road or Silk Route was an ancient network of trade routes that were for centuries central to cultural interaction originally through regions of Eurasia connecting the East and West and stretching from the Korean peninsula and Japan to the Mediterranean Sea . The Silk Road concept refers to both the terrestrial and the maritime routes connecting Asia and Europe . The overland Steppe route stretching through the Eurasian steppe is considered the ancestor to the Silk Road ( s ) . While the term is of modern coinage , the Silk Road derives its name from the lucrative trade in silk ( and horses ) carried out along its length , beginning during the Han dynasty ( 207 BCE -- 220 CE ) . The Han dynasty expanded Central Asian sections of the trade routes around 114 BCE , largely through missions and explorations of the Chinese imperial envoy , Zhang Qian . The Chinese took great interest in the safety of their trade products and extended the Great Wall of China to ensure the protection of the trade route . Trade on the Silk Road played a significant role in the development of the civilizations of China , the Goguryeo kingdom ( Korea ) , Japan , the Indian subcontinent , Persia , Europe , the Horn of Africa and Arabia , opening long-distance political and economic relations between the civilizations . Though silk was certainly the major trade item exported from China , many other goods were traded , as well as religions , syncretic philosophies , and various technologies . Diseases , most notably plague , also spread along the Silk Routes . In addition to economic trade , the Silk Road was a route for cultural trade among the civilizations along its network . The main traders during antiquity included the Chinese , Arabs , Turkmens , Indians , Persians , Somalis , Greeks , Syrians , Romans , Georgians , Armenians , Bactrians , and ( from the 5th to the 8th century ) the Sogdians . In June 2014 , UNESCO designated the Chang ` an-Tianshan corridor of the Silk Road as a World Heritage Site .", "title": "" } ]

Silk remained confined to China until the Silk Road opened at some point during the later half of the first millennium BCE . China maintained its virtual monopoly over silk production for another thousand years . Not confined to clothing , silk was also used for a number of other applications , including writing , and the color of silk worn was an important guide of social class during the Tang Dynasty . Silk cultivation spread to Japan around 300 CE , and , by 522 CE , the Byzantines managed to obtain silkworm eggs and were able to begin silkworm cultivation . The Arabs also began to manufacture silk during this same time . As a result of the spread of sericulture , Chinese silk exports became less important , although they still maintained dominance over the luxury silk market . The Crusades brought silk production to Western Europe , in particular to many Italian states , which saw an economic boom exporting silk to the rest of Europe . Changes in manufacturing techniques also began to take place during the Middle Ages , with devices such as the spinning wheel first appearing . During the 16th century France joined Italy in developing a successful silk trade , though the efforts of most other nations to develop a silk industry of their own were unsuccessful . The Industrial Revolution changed much of Europe 's silk industry . Due to innovations on spinning cotton , cotton became much cheaper to manufacture and therefore caused more expensive silk production to become less mainstream . New weaving technologies , however , increased the efficiency of production . Among these was the Jacquard loom , developed for silk embroidery . An epidemic of several silkworm diseases caused production to fall , especially in France , where the industry never recovered . In the 20th century Japan and China regained their earlier role in silk production , and China is now once again the world 's largest producer of silk .

Lack of FGF21 in mice leads to reduced lifespan.
[ { "docid": "9315213", "text": "BACKGROUND Fibroblast growth factor 21 (FGF21) is a metabolic hormone with pleiotropic effects on glucose and lipid metabolism and insulin sensitivity. It acts as a key downstream target of both peroxisome proliferator-activated receptor α and γ, the agonists of which have been used for lipid lowering and insulin sensitization, respectively. However, the role of FGF21 in the cardiovascular system remains elusive. METHODS AND RESULTS The roles of FGF21 in atherosclerosis were investigated by evaluating the impact of FGF21 deficiency and replenishment with recombinant FGF21 in apolipoprotein E(-/-) mice. FGF21 deficiency causes a marked exacerbation of atherosclerotic plaque formation and premature death in apolipoprotein E(-/-) mice, which is accompanied by hypoadiponectinemia and severe hypercholesterolemia. Replenishment of FGF21 protects against atherosclerosis in apolipoprotein E(-/-)mice via 2 independent mechanisms, inducing the adipocyte production of adiponectin, which in turn acts on the blood vessels to inhibit neointima formation and macrophage inflammation, and suppressing the hepatic expression of the transcription factor sterol regulatory element-binding protein-2, thereby leading to reduced cholesterol synthesis and attenuation of hypercholesterolemia. Chronic treatment with adiponectin partially reverses atherosclerosis without obvious effects on hypercholesterolemia in FGF21-deficient apolipoprotein E(-/-) mice. By contrast, the cholesterol-lowering effects of FGF21 are abrogated by hepatic expression of sterol regulatory element-binding protein-2. CONCLUSIONS FGF21 protects against atherosclerosis via fine tuning the multiorgan crosstalk among liver, adipose tissue, and blood vessels.", "title": "Fibroblast Growth Factor 21 Prevents Atherosclerosis by Suppression of Hepatic Sterol Regulatory Element-Binding Protein-2 and Induction of Adiponectin in Mice" } ]
[ { "docid": "23397658", "text": "Fibroblast growth factor 21 (FGF21), a metabolic hormone predominantly produced by the liver, is also expressed in adipocytes and the pancreas. It regulates glucose and lipid metabolism through pleiotropic actions in these tissues and the brain. In mice, fasting leads to increased PPAR-α mediated expression of FGF21 in the liver where it stimulates gluconeogenesis, fatty acid oxidation, and ketogenesis, as an adaptive response to fasting and starvation. In the fed state, FGF21 acts as an autocrine factor in adipocytes, regulating the activity of PPAR-γ through a feed-forward loop mechanism. Administration of recombinant FGF21 has been shown to confer multiple metabolic benefits on insulin sensitivity, blood glucose, lipid profile and body weight in obese mice and diabetic monkeys, without mitogenic or other side effects. Such findings highlight the potential role of FGF21 as a therapeutic agent for obesity-related medical conditions. However, in human studies, high circulating FGF21 levels are found in obesity and its related cardiometabolic disorders including the metabolic syndrome, type 2 diabetes, non-alcoholic fatty liver disease and coronary artery disease. These findings may indicate the presence of FGF21 resistance or compensatory responses to the underlying metabolic stress, and imply the need for supraphysiological doses of FGF21 to achieve therapeutic efficacy. On the other hand, serum FGF21 has been implicated as a potential biomarker for the early detection of these cardiometabolic disorders.

Unexpectedly, these mice showed decreased fat mass and were protected from diet-induced obesity and insulin resistance; this phenotype was accompanied by increased fatty acid oxidation and browning of white adipose tissue (WAT) owing to induction of fibroblast growth factor 21 (Fgf21). Mitochondrial dysfunction induced by autophagy deficiency increased Fgf21 expression through induction of Atf4, a master regulator of the integrated stress response. Mitochondrial respiratory chain inhibitors also induced Fgf21 in an Atf4-dependent manner. We also observed induction of Fgf21, resistance to diet-induced obesity and amelioration of insulin resistance in mice with autophagy deficiency in the liver, another insulin target tissue. These findings suggest that autophagy deficiency and subsequent mitochondrial dysfunction promote Fgf21 expression, a hormone we consequently term a 'mitokine', and together these processes promote protection from diet-induced obesity and insulin resistance.", "title": "Autophagy deficiency leads to protection from obesity and insulin resistance by inducing Fgf21 as a mitokine" }, { "docid": "1840993", "text": "Fibroblast growth factor 21 (FGF21) is a novel metabolic regulator that represents a promising target for the treatment of several metabolic diseases.

However, the identity of the predominant metabolic tissue in which a major FGFR-KLB resides that critically mediates the differential actions and metabolism effects of FGF19 and FGF21 remain unclear. METHODOLOGY/PRINCIPAL FINDINGS We determined the receptor and tissue specificity of FGF21 in comparison to FGF19 by using direct, sensitive and quantitative binding kinetics, and downstream signal transduction and expression of early response gene upon administration of FGF19 and FGF21 in mice. We found that FGF21 binds FGFR1 with much higher affinity than FGFR4 in presence of KLB; while FGF19 binds both FGFR1 and FGFR4 in presence of KLB with comparable affinity. The interaction of FGF21 with FGFR4-KLB is very weak even at high concentration and could be negligible at physiological concentration. Both FGF19 and FGF21 but not FGF1 exhibit binding affinity to KLB. The binding of FGF1 is dependent on where FGFRs are present. Both FGF19 and FGF21 are unable to displace the FGF1 binding, and conversely FGF1 cannot displace FGF19 and FGF21 binding. These results indicate that KLB is an indispensable mediator for the binding of FGF19 and FGF21 to FGFRs that is not required for FGF1. Although FGF19 can predominantly activate the responses of the liver and to a less extent the adipose tissue, FGF21 can do so significantly only in the adipose tissue and adipocytes. Among several metabolic and endocrine tissues, the response of adipose tissue to FGF21 is predominant, and can be blunted by the ablation of KLB or FGFR1. CONCLUSIONS Our results indicate that unlike FGF19, FGF21 is unable to bind FGFR4-KLB complex with affinity comparable to FGFR1-KLB, and therefore, at physiological concentration less likely to directly and significantly target the liver where FGFR4-KLB predominantly resides. However, both FGF21 and FGF19 have the potential to activate responses of primarily the adipose tissue where FGFR1-KLB resides.", "title": "Differential Specificity of Endocrine FGF19 and FGF21 to FGFR1 and FGFR4 in Complex with KLB" }, { "docid": "2462673", "text": "Activation of self-reactive T cells and their trafficking to target tissues leads to autoimmune organ destruction.

Low birth weight caused by maternal protein restriction followed by catch-up growth (recuperated animals) was associated with shortened lifespan whereas protein restriction and slow growth during lactation (postnatal low protein: PLP animals) increased lifespan. We aim to explore the mechanistic basis by which these differences arise. Here we investigated effects of maternal diet on organ growth, metabolic parameters and the expression of insulin/IGF1 signalling proteins and Sirt1 in muscle of male mice at weaning. PLP mice which experienced protein restriction during lactation had lower fasting glucose (P = 0.038) and insulin levels (P = 0.046) suggesting improved insulin sensitivity. PLP mice had higher relative weights (adjusted by body weight) of brain (P = 0.0002) and thymus (P = 0.031) compared to controls suggesting that enhanced functional capacity of these two tissues is beneficial to longevity. They also had increased expression of insulin receptor substrate 1 (P = 0.021) and protein kinase C zeta (P = 0.046). Recuperated animals expressed decreased levels of many insulin signalling proteins including PI3 kinase subunits p85alpha (P = 0.018), p110beta (P = 0.048) and protein kinase C zeta (P = 0.006) which may predispose these animals to insulin resistance.

This systemic response included the same biological processes that are triggered in progeroid and long-lived mice. However, on a genome-wide scale, transcriptomes of naturally aged mice showed a strong association to progeroid but not to long-lived mice.

Notably, age-associated DNA methylation changes comprise a so-called aging \"clock\", a robust biomarker of aging. However, while genetic, dietary and drug interventions can extend lifespan, their impact on the epigenome is uncharacterised. To fill this knowledge gap, we defined age-associated DNA methylation changes at the whole-genome, single-nucleotide level in mouse liver and tested the impact of longevity-promoting interventions, specifically the Ames dwarf Prop1 df/df mutation, calorie restriction and rapamycin. RESULTS In wild-type mice fed an unsupplemented ad libitum diet, age-associated hypomethylation was enriched at super-enhancers in highly expressed genes critical for liver function. Genes harbouring hypomethylated enhancers were enriched for genes that change expression with age. Hypermethylation was enriched at CpG islands marked with bivalent activating and repressing histone modifications and resembled hypermethylation in liver cancer. Age-associated methylation changes are suppressed in Ames dwarf and calorie restricted mice and more selectively and less specifically in rapamycin treated mice. CONCLUSIONS Age-associated hypo- and hypermethylation events occur at distinct regulatory features of the genome. Distinct longevity-promoting interventions, specifically genetic, dietary and drug interventions, suppress some age-associated methylation changes, consistent with the idea that these interventions exert their beneficial effects, in part, by modulation of the epigenome.

In situ hybridization revealed Isl1 expression in the mesenchymal cells surrounding the base of the ureteric bud in mice. Conditional deletion of Isl1 caused kidney agenesis or hypoplasia and hydroureter, a phenotype resembling human congenital anomalies of the kidney and urinary tract (CAKUT). The absence of Isl1 led to ectopic branching of the ureteric bud out from the nephric duct or to the formation of accessory buds, both of which could lead to obstruction of the ureter-bladder junction and consequent hydroureter. The abnormal elongation and poor branching of the ureteric buds were the likely causes of the kidney agenesis or hypoplasia. Furthermore, the lack of Isl1 reduced the expression of Bmp4, a gene implicated in the CAKUT-like phenotype, in the metanephric region before ureteric budding. In conclusion, Isl1 is essential for proper development of the kidney and ureter by repressing the aberrant formation of the ureteric bud.

How much credit you are willing to extend will vary greatly, depending on the amount and the trustworthiness of the party. For example, if you are charging $50 for something, you probably won't bother to collect money upfront, whereas if you are charging $5,000 you probably would collect some upfront. But if the party you are working for is a large financially sound company, the number may be even much higher than $5K as you can trust you will be paid. Obviously there are many factors that go into how much credit you are willing to extend to your customer. (This is why credit reports exist for banks to determine how much credit to extend to you.) As for the specific case you are asking about, which may be classified as a decent amount of work for a small business, I would default to having a written scope of work, a place in the document for both parties to sign, and specify 50% upfront payment and 50% payment at completion. When you receive the signed document and the upfront payment (and possibly even after the check clears), you begin work. I would call this my \"\"default contract\"\" and adjust according to your needs depending on the size of the job and the trustworthiness of the customer. As for your question about how to deposit the check, that depends on what type of entity you are. If you are a sole proprietor you should ask for the checks to be made out to you. If you are a business then the checks should be made out to your business name. You don't need \"\"in trust\"\" or anything similar because your customer, after paying the upfront fee, must trust that you will do the work you promise to do, just like you have to trust that after completing the work you will receive the final payment.

Tip: having done the \"\"default\"\" contract many times in my career, both as a sole proprietor and a business owner, I can assure you there is a big difference between a potential customer agreeing to something in advance, and actually writing a check.

Therefore this kind of market manipulation is coupled with \"\"promotions\"\" to attract liquidity to a financial product. (NOTE the mere fact of a promotion does not mean that illegal trading behavior is occurring, but it does usually mean that someone else is selling into the liquidity) Another way to make this kind of trading behavior profitable is via the derivatives market. Options contracts are priced solely by the trading price of the underlying asset, so even if your multiple account trading could only at best break even when you sell your final holdings (basically resetting the price to where it was because you started distorting it), this is fine because your real trade is in the options market. Lets say Apple was trading at $200 , the options contract at the $200 strike is a call trading at $1 with no intrinsic value. You can buy to open several thousand of the $200 strike without distorting the shares market at all, then in the shares market you bid up Apple to $210, now your options contract is trading at $11 with $10 of intrinsic value, so you just made 1000% gain and are able to sell to close those call options. Then you unwind the rest of your trade and sell your $210 apple shares, probably for $200 or $198 or less (because there are few market participants that actually valued the shares for that high, the real bidders are at $200 and lower). This is hardly a discreet thing to do, so like I mentioned before, this is illegal in markets where actual company shares are involved and should not be attempted in stock markets but other markets won't have the same prohibitions, this is a general inefficiency in capital markets in general and certain derivatives pricing formulas. It is important to understand these things if you plan to participate in markets that claim to be fair. There is nothing novel about this sort of thing, and it is just a problem of allocating enough capital to do so.\"", "title": "" }, { "docid": "416317", "text": "\"That's not the case where I'm located.

On ETNs, they often (always?) settle in cash. As an example of an option I'm currently looking at, AVSPY, it settles in cash (please confirm by reading the documentation on this set of options at http://www.nasdaqomxtrader.com/Micro.aspx?id=Alpha, but it is an example of this). There's nothing it can settle into (as you can't purchase the AVSPY index, only options on it). You may quickly look (wikipedia) at the difference between \"\"American Style\"\" options and \"\"European Style\"\" options, for more understanding here. Interestingly I just spoke to my broker about this subject for a trade execution. Before I go into that, let me also quickly refer to Joe's answer: what you buy, you can sell. That's one of the jobs of a market maker, to provide liquidity in a market. So, when you buy a stock, you can sell it. When you buy an option, you can sell it. That's at any time before expiration (although how close you do it before the closing bell on expiration Friday/Saturday is your discretion). When a market maker lists an option price, they list a bid and an ask. If you are willing to sell at the bid price, they need to purchase it (generally speaking). That's why they put a spread between the bid and ask price, but that's another topic not related to your question -- just note the point of them buying at the bid price, and selling at the ask price -- that's what they're saying they'll do. Now, one major difference with options vs. stocks is that options are contracts. So, therefore, we can note just as easily that YOU can sell the option on something (particularly if you own either the underlying, or an option deeper in the money). If you own the underlying instrument/stock, and you sell a CALL option on it, this is a strategy typically referred to as a covered call, considered a \"\"risk reduction\"\" strategy. You forfeit (potential) gains on the upside, for money you receive in selling the option. The point of this discussion is, is simply: what one buys one can sell; what one sells one can buy -- that's how a \"\"market\"\" is supposed to work. And also, not to think that making money in options is buying first, then selling. It may be selling, and either buying back or ideally that option expiring worthless. -- Now, a final example. Let's say you buy a deep in the money call on a stock trading at $150, and you own the $100 calls. At expiration, these have a value of $50. But let's say, you don't have any money in your account, to take ownership of the underlying security (you have to come up with the additional $100 per share you are missing). In that case, need to call your broker and see how they handle it, and it will depend on the type of account you have (e.g. margin or not, IRA, etc). Generally speaking though, the \"\"margin department\"\" makes these decisions, and they look through folks that have options on things that have value, and are expiring, and whether they have the funds in their account to absorb the security they are going to need to own. Exchange-wise, options that have value at expiration, are exercised. But what if the person who has the option, doesn't have the funds to own the whole stock? Well, ideally on Monday they'll buy all the shares with the options you have at the current price, and immediately liquidate the amount you can't afford to own, but they don't have to.

If in the 61-day period around the sale of stock (30 days before and 30 days after), you also acquire the same stock (including by contract or option), then it washes out your loss. If you held your stock for a while, then in a 61-day period bought more, and sold some, then any loss would be washed out by the acquisition. Of course it is also a wash sale if your purchase of the stock follows your sale, rather than precedes it. Your disallowed loss goes into the basis of your stock holding, so will be meaningful when you do have a true economic sale of that stock. From IRS Pub 550: A wash sale occurs when you sell or trade stock or securities at a loss and within 30 days before or after the sale you: Buy substantially identical stock or securities, Acquire substantially identical stock or securities in a fully taxable trade, Acquire a contract or option to buy substantially identical stock or securities, or Acquire substantially identical stock for your individual retirement account (IRA) or Roth IRA.

Options therefore are the insurance policy of the free market. You negotiate a future price (actually you usually take what you can get if you're an individual investor; the institutional fund managers get to negotiate because they're moving billions around every day), then you pay the other guy up front for the right of refusal later. How much you pay depends on how likely the person giving you this option is to have to make good on it; if your position looks like a sure thing, an option's going to be very expensive (and if it's such a sure thing, you should just make your move on the spot market; it's thus useful to track futures prices to see where the various big players are predicting that your portfolio will move). A put option, which is an option for you to sell something at a future price, is a hedge against loss of value of your portfolio. You can take one out on any single item in your portfolio, or against a portion or even your entire portfolio. If the stock loses value such that the contract price is better than the market price as of the delivery date of the contract, you execute the option; otherwise, you let it expire. A call option, which is an option to buy something at a future price, is a hedge against rising costs. The rough analog is a \"\"pre-order\"\" in retail (but more like a \"\"holding fee\"\"). They're unusual in portfolio management but can be useful when moving money around in more complex ways. Basically, if you need to guarantee that you will not pay more than a certain per-share price to buy something in the future, you buy a call option. If the spot price as of the delivery date is less than the contract price, you buy from the market and ignore the contract, while if prices have soared, you exercise it and get the lower contract price. Stock options, offered as benefits in many companies, are a specific form of call option with very generous terms for whomever holds them. A swaption, basically a put and a call rolled into one, allows you to trade something for something else. Call it the free market's \"\"exchange policy\"\". For a price, if a security you currently hold loses value, you can exchange it for something else that you predicted would become more valuable at the same time. One example might be airline stocks and crude oil; when crude spikes, airline stocks generally suffer, and you can take advantage of this, if it happens, with a swaption to sell your airline stocks for crude oil certificates.

It won't return much interest, but it will return some and it is easily accessible. If you have all your emergency savings that you need (at least six months of income), buy index-based mutual funds. These should invest in a broad range of securities including both stocks and bonds (three dollars in stocks for every dollar in bonds) so as to be robust in the face of market shifts. You should not buy individual stocks unless you have enough money to buy a lot of them in different industries. Thirty different stocks is a minimum for a diversified portfolio, and you really should be looking at more like a hundred. There's also considerable research effort required to verify that the stocks are good buys. For most people, this is too much work. For most people, broad-based index funds are better purchases. You don't have as much upside, but you also are much less likely to find yourself holding worthless paper. If you do buy stocks, look for ones where you know something about them. For example, if you've been to a restaurant chain with a recent IPO that really wowed you with their food and service, consider investing. But do your research, so that you don't get caught buying after everyone else has already overbid the price. The time to buy is right before everyone else notices how great they are, not after. Some people benefit from joining investment clubs with others with similar incomes and goals. That way you can share some of the research duties. Also, you can get other opinions before buying, which can restrain risky impulse buys. Just to reiterate, I would recommend sticking to mutual funds and saving accounts for most investors. Only make the move into individual stocks if you're willing to be serious about it. There's considerable work involved. And don't forget diversification. You want to have stocks that benefit regardless of what the overall economy does. Some stocks should benefit from lower oil prices while others benefit from higher prices. You want to have both types so as not to be caught flat-footed when prices move. There are much more experienced people trying to guess market directions. If your strategy relies on outperforming them, it has a high chance of failure. Index-based mutual funds allow you to share the diversification burden with others.

Now that you have narrowed down your choices, it is time to make your final decision on which company and security system you will go with. Always remember that cheaper is not always better. It is always a good idea to use a company you feel the most secure with and who you feel can provide the best security for your home.

And to expand on the idea of \"\"cancelling\"\" an option you purchased: No, you cannot \"\"cancel\"\" an option contract, per se. But, you are permitted to sell the call option to somebody else willing to buy, via the market. When you sell your call option, you'll either make or lose money on the sale – depending on the price of the underlying shares at the time (are they in- or out- of the money?), volatility in the market, and remaining time value. Once you sell, you're back to \"\"no position\"\". That's not the same as \"\"cancelled\"\", but you are out of the trade, whether at profit or loss. Furthermore, the option writer (i.e. the seller who \"\"sold to open\"\" a position, in writing the call in the first place) is also not permitted to cancel the option he wrote. However, the option writer is permitted to close out the original short position by simply buying back a matching call option on the market. Again, this would occur at either profit or loss based on market prices at the time. This second kind of buy order – i.e. made by someone who initially wrote a call option – is called a \"\"buy to close\"\", meaning the purchase of an offsetting position. (The other kind of buy is the \"\"buy to open\"\".) Then, consider: Since an option buyer is free to re-sell the option purchased, and since an option writer (who \"\"sold to open\"\" the new contract) is also free to buy back an offsetting option, a process known as clearing is required to match remaining buyers exercising the call options held with the remaining option writers having open short positions for the contract. For CBOE options, this clearing is performed by the Options Clearing Corporation. Here's how it works (see here): What is the OCC? The Options Clearing Corporation is the sole issuer of all securities options listed at the CBOE, four other U.S. stock exchanges and the National Association of Securities Dealers, Inc. (NASD), and is the entity through which all CBOE option transactions are ultimately cleared. As the issuer of all options, OCC essentially takes the opposite side of every option traded. Because OCC basically becomes the buyer for every seller and the seller for every buyer, it allows options traders to buy and sell in a secondary market without having to find the original opposite party. [...]   [emphasis above is mine] When a call option writer must deliver shares to a call option buyer exercising a call, it's called assignment. (I have been assigned before, and it isn't pleasant to see a position called away that otherwise would have been very profitable if the call weren't written in the first place!) Also, re: \"\"I know my counter party cannot sell his shares\"\" ... that's not strictly true. You are thinking of a covered call. But, an option writer doesn't necessarily need to own the underlying shares. Look up Naked call (Wikipedia). Naked calls aren't frequently undertaken because a naked call \"\"is one of the riskiest options strategies because it carries unlimited risk\"\". The average individual trader isn't usually permitted by their broker to enter such an order, but there are market participants who can do such a trade.

And I am not a lawyer. But for what it's worth: Did you sign a written contract with H&R Block? If so, then the terms of that contract would govern. If you signed a contract saying that you agree to file your taxes through them if they meet such-and-such conditions, and they met these conditions, then you are legally obligated. If there was no written contract, then I think any court would take the conversation between you and H&R Block as an oral contract. If H&R Block said, basically, \"\"Okay, we'll calculate what we think your taxes are, and if we come up with something better than what you had before, then you agree to file your taxes through us\"\", and you said \"\"Oh, okay\"\", then that's an oral contract. You agreed to their conditions. Legally, oral contracts are just as binding as written contracts. The only difference is that it is difficult to prove exactly what was said. If you really did agree to these conditions, I suppose you could lie and say you didn't and then try to convince a court that they are the ones lying. Obvious ethical problems there. There are also implied contracts. If HRB's advertising or paperwork says that you're agreeing to file through them if they meet the conditions, I thing that a court would likely rule that you implicitly agreed to their terms by doing the review.

So if they give you the benefit of their expertise -- they tell you how to reduce your taxes -- and then you don't pay them, that seems rather unethical to me. The situation is muddied by the fact that you paid $100 for the review. Is that paying for the basic information, the \"\"tax tip\"\", and paying for them to file is then a contract for additional work? Under some circumstances I'd say yes, that's additional work and thus an additional contract, so in the absence of a contract obligating me, I don't have to do that.

When you sell that investment, and take the cheque into the foreign bank and wire it back to the USA in US dollars, you will definitely obtain the final value of the investment, converted to US$. Thats what you wanted, right? You'll get that. If you also hedge, unless you have a situation where it is a perfect hedge, then you are gambling on what the currencies will do. A perfect hedge is unusual for what most individuals are involved in. It looks something like this: you know ForeignCorp is going to pay you 10 million quatloos on Dec 31. So you go to a bank (probably a foreign bank, I've found they have lower limits for this kind of transaction and more customizable than what you might create trading futures contracts), and tell them, \"\"I have this contract for a 10 million quatloo receivable on Dec 31, I'd like to arrange a FX forward contract and lock in a rate for this in US$/quatloo.\"\" They may have a credit check or a deposit for such an arrangement, because as the rates change either the bank will owe you money or you will owe the bank money. If they quote you 0.05 US$/quatloo, then you know that when you hand the cheque over to the bank your contract payment will be worth US$500,000. The forward rate may differ from the current rate, thats how the bank accounts for risk and includes a profit. Even with a perfect hedge, you should be able to see the potential for trouble. If the bank doesnt quite trust you, and hey, banks arent known for trust, then as the quatloo strengthens relative to the US$, they may suspect that you will walk away from the deal. This risk can be reduced by including terms in the contract requiring you to pay the bank some quatloos as that happens. If the quatloo falls you would get this money credited back to your account. This is also how futures contracts work; there it is called \"\"mark to market accounting\"\". Trouble lurks here. Some people, seeing how they are down money on the hedge, cancel it.

The future can be over something tangible like pork bellies or oil, in which case there is a physical transfer of \"\"stuff\"\" or it can be over something intangible like shares. The purpose of the contract is to allow the seller to \"\"lock-in\"\" a price so that they are not subject to price fluctuations between the date the contract is entered and the date it is complete; this risk is transferred to the seller who will therefore generally pay a discounted rate from the spot price on the original day. In many cases, the buyer actually wants the \"\"stuff\"\"; futures contracts between farmers and manufacturers being one example. The farmer who is growing, say, wool will enter a contract to supply 3000kg at $10 per kg (of a given quality etc. there are generally price adjustments detailed for varying quality) with a textile manufacturer to be delivered in 6 months. The spot price today may be $11 - the farmer gives up $1 now to shift the risk of price fluctuations to the manufacturer. When the strike date rolls around the farmer delivers the 3000kg and takes the money - if he has failed to grow at least 3000kg then he must buy it from someone or trigger whatever the penalty clauses in the contract are. For futures over shares and other securities the principle is exactly the same. Say the contract is for 1000 shares of XYZ stock. Party A agrees to sell these for $10 each on a given day to party B. When that day rolls around party A transfers the shares and gets the money. Party A may have owned the shares all along, may have bought them before the settlement day or, if push comes to shove, must buy them on the day of settlement.

Good luck.\"", "title": "" }, { "docid": "140830", "text": "\"Depositum irregulare is a Latin phrase that simply means \"\"irregular deposit.\"\" It's a concept from ancient Roman contract law that has a very narrow scope and doesn't actually apply to your example. There are two distinct parts to this concept, one dealing with the notion of a deposit and the other with the notion of irregularity. I'll address them both in turn since they're both relevant to the tax issue. I also think that this is an example of the XY problem, since your proposed solution (\"\"give my money to a friend for safekeeping\"\") isn't the right solution to your actual problem (\"\"how can I keep my money safe\"\"). The currency issue is a complication, but it doesn't change the fact that what you're proposing probably isn't a good solution. The key word in my definition of depositum irregulare is \"\"contract\"\". You don't mention a legally binding contract between you and your friend; an oral contract doesn't qualify because in the event of a breach, it's difficult to enforce the agreement. Legally, there isn't any proof of an oral agreement, and emotionally, taking your friend to court might cost you your friendship. I'm not a lawyer, but I would guess that the absence of a contract implies that even though in the eyes of you and your friend, you're giving him the money for \"\"safekeeping,\"\" in the eyes of the law, you're simply giving it to him. In the US, you would owe gift taxes on these funds if they're higher than a certain amount. In other words, this isn't really a deposit. It's not like a security deposit, in which the money may be held as collateral in exchange for a service, e.g. not trashing your apartment, or a financial deposit, where the money is held in a regulated financial institution like a bank. This isn't a solution to the problem of keeping your money safe because the lack of a contract means you incur additional risk in the form of legal risk that isn't present in the context of actual deposits. Also, if you don't have an account in the right currency, but your friend does, how are you planning for him to store the money anyway? If you convert your money into his currency, you take on exchange rate risk (unless you hedge, which is another complication). If you don't convert it and simply leave it in his safe, house, car boot, etc. you're still taking on risk because the funds aren't insured in the event of loss. Furthermore, the money isn't necessarily \"\"safe\"\" with your friend even if you ignore all the risks above. Without a written contract, you have little recourse if a) your friend decides to spend the money and not return it, b) your friend runs into financial trouble and creditors make claim to his assets, or c) you get into financial trouble and creditors make claims to your assets. The idea of giving money to another individual for safekeeping during bankruptcy has been tested in US courts and ruled invalid. If you do decide to go ahead with a contract and you do want your money back from your friend eventually, you're in essence loaning him money, and this is a different situation with its own complications. Look at this question and this question before loaning money to a friend. Although this does apply to your situation, it's mostly irrelevant because the \"\"irregular\"\" part of the concept of \"\"irregular deposit\"\" is a standard feature of currencies and other legal tender. It's part of the fungibility of modern currencies and doesn't have anything to do with taxes if you're only giving your friend physical currency. If you're giving him property, other assets, etc. for \"\"safekeeping\"\" it's a different issue entirely, but it's still probably going to be considered a gift or a loan. You're basically correct about what depositum irregulare means, but I think you're overestimating its reach in modern law. In Roman times, it simply refers to a contract in which two parties made an agreement for the depositor to deposit money or goods with the depositee and \"\"withdraw\"\" equivalent money or goods sometime in the future. Although this is a feature of the modern deposit banking system, it's one small part alongside contract law, deposit insurance, etc. These other parts add complexity, but they also add security and risk mitigation. Your arrangement with your friend is much simpler, but also much riskier. And yes, there probably are taxes on what you're proposing because you're basically giving or loaning the money to your friend. Even if you say it's not a loan or a gift, the law may still see it that way. The absence of a contract makes this especially important, because you don't have anything speaking in your favor in the event of a legal dispute besides \"\"what you meant the money to be.\"\" Furthermore, the money isn't necessarily safe with your friend, and the absence of a contract exacerbates this issue. If you want to keep your money safe, keep it in an account that's covered by deposit insurance. If you don't have an account in that currency, either a) talk to a lawyer who specializes in situation like this and work out a contract, or b) open an account with that currency. As I've stated, I'm not a lawyer, so none of the above should be interpreted as legal advice. That being said, I'll reiterate again that the concept of depositum irregulare is a concept from ancient Roman law. Trying to apply it within a modern legal system without a contract is a potential recipe for disaster. If you need a legal solution to this problem (not that you do; I think what you're looking for is a bank), talk to a lawyer who understands modern law, since ancient Roman law isn't applicable to and won't pass muster in a modern-day court.\"", "title": "" }, { "docid": "229777", "text": "In the event that payment is not made by the due date on the invoice then the transaction is essentially null and void and you can sell the work to another client.

In this contract you need to either enforce payment in full at time of signing or a deposit at signing with payment in full within (X) amount of days and upon delivery of item. In your sales contract you will want to stipulate a late fee in the event that the client does not pay the balance by the date specified, and a clause that stipulates how long after the due date that you will hold the artwork before the client forfeiting deposit and losing rights to the work. You will also want to specify an amount of time that you provide as a grace period in the event client changes their mind about the purchase, and you can make it zero grace period, making all sales final and upon signing of the agreement the client agrees to the terms and is locked into the sale. In which point if they back out they forfeit all deposits paid.

Then she's suing Mastercard for false light, a type of defamtion there the facts are true but are framed falsely. And defamation has much more serious consequences in Europe. Anyway, even a business not at fault has to pay for a PCI-DSS audit. A business at fault has lots more problems, at the very least paying $50-90 per customer to replace their cards. The simple fact is 80% of businesses in this situation go bankrupt at this point. Usually fraudsters make automated attacks using scripts they got from others. Only a few dozen attacks (on sites) succeed, and then they use other scripts to intercept payment data, which is all they want. They are cookie cutter scripts, and aren't customized for each site, and can't go after whatever personal data is particular to that site. So in most cases all they get is payment data. It's also likely that primary data, like a cloud drive, photo collection or medical records, are kept in completely separate systems with separate security, unlikely to hack both at once even if the hacker is willing to put lots and lots of engineering effort into it.

Aspartame is composed of phenylalanine (50%), aspartic acid (40%) and methanol (10%). Phenylalanine plays an important role in neurotransmitter regulation, whereas aspartic acid is also thought to play a role as an excitatory neurotransmitter in the central nervous system. Glutamate, asparagines and glutamine are formed from their precursor, aspartic acid. Methanol, which forms 10% of the broken down product, is converted in the body to formate, which can either be excreted or can give rise to formaldehyde, diketopiperazine (a carcinogen) and a number of other highly toxic derivatives. Previously, it has been reported that consumption of aspartame could cause neurological and behavioural disturbances in sensitive individuals. Headaches, insomnia and seizures are also some of the neurological effects that have been encountered, and these may be accredited to changes in regional brain concentrations of catecholamines, which include norepinephrine, epinephrine and dopamine. The aim of this study was to discuss the direct and indirect cellular effects of aspartame on the brain, and we propose that excessive aspartame ingestion might be involved in the pathogenesis of certain mental disorders (DSM-IV-TR 2000) and also in compromised learning and emotional functioning.", "title": "Direct and indirect cellular effects of aspartame on the brain." }, { "docid": "MED-1848", "text": "BACKGROUND: In a cross-sectional case-control study conducted in northern Italy, 64 former aluminium dust-exposed workers were compared with 32 unexposed controls from other companies matched for age, professional training, economic status, educational and clinical features. The findings lead the authors to suggest a possible role of the inhalation of aluminium dust in pre-clinical mild cognitive disorder which might prelude Alzheimer's disease (AD) or AD-like neurological deterioration. METHODS: The investigation involved a standardised occupational and medical history with particular attention to exposure and symptoms, assessments of neurotoxic metals in serum: aluminium (Al-s), copper (Cu-s) and zinc (Zn-s), and in blood: manganese (Mn-b), lead (Pb-b) and iron (Fe-b). Cognitive functions were assessed by the Mini Mental State Examination (MMSE), the Clock Drawing Test (CDT) and auditory evoked Event-Related Potential (ERP-P300). To detect early signs of mild cognitive impairment (MCI), the time required to solve the MMSE (MMSE-time) and CDT (CDT-time) was also measured. RESULTS: Significantly higher internal doses of Al-s and Fe-b were found in the ex-employees compared to the control group. The neuropsychological tests showed a significant difference in the latency of P300, MMSE score, MMSE-time, CDT score and CDT-time between the exposed and the control population. P300 latency was found to correlate positively with Al-s and MMSE-time. Al-s has significant effects on all tests: a negative relationship was observed between internal Al concentrations, MMSE score and CDT score; a positive relationship was found between internal Al concentrations, MMSE-time and CDT-time. All the potential confounders such as age, height, weight, blood pressure, schooling years, alcohol, coffee consumption and smoking habit were taken into account. CONCLUSIONS: These findings suggest a role of aluminium in early neurotoxic effects that can be detected at a pre-clinical stage by P300, MMSE, MMSE-time, CDT-time and CDT score, considering a 10 micrograms/l cut-off level of serum aluminium, in aluminium foundry workers with concomitant high blood levels of iron.

We highlight both the potential benefits and drawbacks of using this chemopreventive agent for treating osteoarthritis (OA). We also explore the recent literature on the molecular mechanisms of curcumin mediated alterations in gene expression mediated via activator protein 1 (AP-1)/nuclear factor-kappa B (NF-kappaB) signalling in chondrocytes, osteoblasts and synovial fibroblasts. METHODS: A computer-aided search of the PubMed/Medline database aided by a text-mining tool to interrogate the ResNet Mammalian database 6.0. RESULTS: Recent work has shown that curcumin protects human chondrocytes from the catabolic actions of interleukin-1 beta (IL-1beta) including matrix metalloproteinase (MMP)-3 up-regulation, inhibition of collagen type II and down-regulation of beta1-integrin expression. Curcumin blocks IL-1beta-induced proteoglycan degradation, AP-1/NF-kappaB signalling, chondrocyte apoptosis and activation of caspase-3. CONCLUSIONS: The available data from published in vitro and in vivo studies suggest that curcumin may be a beneficial complementary treatment for OA in humans and companion animals. Nevertheless, before initiating extensive clinical trials, more basic research is required to improve its solubility, absorption and bioavailability and gain additional information about its safety and efficacy in different species. Once these obstacles have been overcome, curcumin and structurally related biochemicals may become safer and more suitable nutraceutical alternatives to the non-steroidal anti-inflammatory drugs that are currently used for the treatment of OA.

RECENT FINDINGS: Berryfruit supplementation has continued to demonstrate efficacy in reversing age-related cognitive decline in animal studies. In terms of the mechanisms behind the effects of berries on the central nervous system, recent studies have demonstrated the bioavailability of berry polyphenols in several animal models. These studies have revealed that flavonoids and polyphenols from berries do accumulate in the brain following long-term consumption. Finally, several compelling studies have revealed that berries can influence cell-signaling cascades both in vivo and in cell culture systems. These studies underscore the developing theory that berries and antioxidant-rich foods may be acting as more than just oxygen radical neutralizers in the aging central nervous system. SUMMARY: Antioxidant-rich berries consumed in the diet can positively impact learning and memory in the aged animal. This effect on cognition is thought to be due to the direct interaction of berry polyphenols with aging neurons, reducing the impact of stress-related cellular signals and increasing the capacity of neurons to maintain proper functioning during aging.", "title": "Recent advances in berry supplementation and age-related cognitive decline." }, { "docid": "MED-5258", "text": "Background Coffee is one of the most widely consumed beverages, but the association between coffee consumption and the risk of death remains unclear.

Participants with cancer, heart disease, and stroke were excluded. Coffee consumption was assessed once at baseline. Results During 5,148,760 person-years of follow-up between 1995 and 2008, a total of 33,731 men and 18,784 women died. In age-adjusted models, the risk of death was increased among coffee drinkers. However, coffee drinkers were also more likely to smoke, and, after adjustment for tobacco-smoking status and other potential confounders, there was a significant inverse association between coffee consumption and mortality. Adjusted hazard ratios for death among men who drank coffee as compared with those who did not were as follows: 0.99 (95% confidence interval [CI], 0.95 to 1.04) for drinking less than 1 cup per day, 0.94 (95% CI, 0.90 to 0.99) for 1 cup, 0.90 (95% CI, 0.86 to 0.93) for 2 or 3 cups, 0.88 (95% CI, 0.84 to 0.93) for 4 or 5 cups, and 0.90 (95% CI, 0.85 to 0.96) for 6 or more cups of coffee per day (P<0.001 for trend); the respective hazard ratios among women were 1.01 (95% CI, 0.96 to 1.07), 0.95 (95% CI, 0.90 to 1.01), 0.87 (95% CI, 0.83 to 0.92), 0.84 (95% CI, 0.79 to 0.90), and 0.85 (95% CI, 0.78 to 0.93) (P<0.001 for trend).

The aim of this prospective study is to investigate for the first time the association between dietary acrylamide intake and the risk of several histological subtypes of lymphatic malignancies. Methods The Netherlands Cohort Study on diet and cancer includes 120,852 men and women followed-up since September 1986.

Acrylamide intake was estimated from a food frequency questionnaire combined with acrylamide data for Dutch foods. Hazard ratios (HRs) were calculated for acrylamide intake as a continuous variable as well as in categories (quintiles and tertiles), for men and women separately and for never-smokers, using multivariable-adjusted Cox proportional hazards models. Results After 16.3 years of follow-up, 1,233 microscopically confirmed cases of lymphatic malignancies were available for multivariable-adjusted analysis.

DESIGN, SETTING, AND PARTICIPANTS: Randomized trial with enrollment at 4 clinical centers (January 2000-June 2001) among 810 adults (mean [SD] age, 50 [8.9] years; 62% women; 34% African American) with above-optimal BP, including stage 1 hypertension (120-159 mm Hg systolic and 80-95 mm Hg diastolic), and who were not taking antihypertensive medications. INTERVENTION: Participants were randomized to one of 3 intervention groups: (1) \"established,\" a behavioral intervention that implemented established recommendations (n = 268); (2) \"established plus DASH,\"which also implemented the DASH diet (n = 269); and (3) an \"advice only\" comparison group (n = 273).

Other flavonoids in dietary vegetable foods that are responsible for anti-invasive and anti-metastatic activities of tumors include luteolin,apigenin, myricetin, tangeretin, kaempferol, glycitein, licoricidin,daidzein, and naringenin. To effectively overcome the metastatic cascade, including cell-cell attachment, tissue barrier degradation, migration, invasion, cell-matrix adhesion,and angiogenesis, it is essential that a bioactive compound prevent tumor cells from metastasizing. This review summarizes the effects of flavonoids on the metastatic cascade and the related proteins, the in vitro anti-invasive activity of flavonoids against cancer cells, and the effects of flavonoids on antiangiogenic and in vivo anti-metastatic models. The available scientific evidence indicates that flavonoids are a ubiquitous dietary phenolics subclass and exert extensive in vitro anti-invasive and in vivo anti-metastatic activities.", "title": "Flavonoids, a ubiquitous dietary phenolic subclass, exert extensive in vitro anti-invasive and in vivo anti-metastatic activities." }, { "docid": "MED-3771", "text": "OBJECTIVE: Hyperosmotic stress on cells limits many aspects of cell function, metabolism and health. International data suggest that schoolchildren may be at risk of hyperosmotic stress on cells because of suboptimal water intake. The present study explored the cell hydration status of two samples of children in the USA. DESIGN: Cross-sectional study describing the urine osmolality (an index of hyperosmotic cell shrinkage) and water intake of convenience samples from Los Angeles (LA) and New York City (NYC). SETTING: Each participant collected a urine sample at an outpatient clinic on the way to school on a weekday morning in spring 2009. Each was instructed to wake, eat, drink and do as usual before school, and complete a dietary record form describing the type and amounts of all foods and beverages consumed after waking, before giving the sample. SUBJECTS: The children (9-11 years) in LA (n 337) and NYC (n 211) considered themselves healthy enough to go to school on the day they gave the urine sample. RESULTS: Elevated urine osmolality (>800 mmol/kg) was observed in 63 % and 66 % of participants in LA and NYC, respectively. In multivariable-adjusted logistic regression models, elevated urine osmolality was associated with not reporting intake of drinking water in the morning (LA: OR = 2·1, 95 % CI 1·2, 3·5; NYC: OR = 1·8, 95 % CI 1·0, 3·5).

Aspalathus linearis (Rooibos), which has been reported to aid stress-related symptoms linked to metabolic diseases, contains a wide spectrum of bioactive phenolic compounds of which aspalathin is unique. In this study the inhibitory effects of Rooibos and the dihydrochalcones, aspalathin and nothofagin, were investigated on adrenal steroidogenesis. The activities of both cytochrome P450 17α-hydroxylase/17,20 lyase and cytochrome P450 21-hydroxylase were significantly inhibited in COS-1 cells. In order to study the effect of these compounds in H295R cells, a human adrenal carcinoma cell line, a novel UPLC-MS/MS method was developed for the detection and quantification of twenty-one steroid metabolites using a single chromatographic separation. Under both basal and forskolin-stimulated conditions, the total amount of steroids produced in H295R cells significantly decreased in the presence of Rooibos, aspalathin and nothofagin. Under stimulated conditions, Rooibos decreased the total steroid output 4-fold and resulted in a significant reduction of aldosterone and cortisol precursors. Dehydroepiandrosterone-sulfate levels were unchanged, while the levels of androstenedione (A4) and 11β-hydroxyandrostenedione (11βOH-A4) were inhibited 5.5 and 2.3-fold, respectively. Quantification of 11βOH-A4 showed this metabolite to be a major product of steroidogenesis in H295R cells and we confirm, for the first time, that this steroid metabolite is the product of the hydroxylation of A4 by human cytochrome P450 11β-hydroxylase. Taken together our results demonstrate that Rooibos, aspalathin and nothofagin influence steroid hormone biosynthesis and the flux through the mineralocorticoid, glucocorticoid and androgen pathways, thus possibly contributing to the alleviation of negative effects arising from elevated glucocorticoid levels.

Although the pathogenesis of obesity-associated osteoarthritis is not completely understood, recent studies indicate that pro-inflammatory metabolic factors contribute to an increase in osteoarthritis risk. Adipose tissue, and in particular infrapatellar fat, is a local source of pro-inflammatory mediators that are increased with obesity and have been shown to increase cartilage degradation in cell and tissue culture models. One adipokine in particular, leptin, may be a critical mediator of obesity-associated osteoarthritis via synergistic actions with other inflammatory cytokines. Biomechanical factors may also increase the risk of osteoarthritis by activating cellular inflammation and promoting oxidative stress. However, some types of biomechanical stimulation, such as physiologic cyclic loading, inhibit inflammation and protect against cartilage degradation. A high percentage of obese individuals with knee osteoarthritis are sedentary, suggesting that a lack of physical activity may increase the susceptibility to inflammation. A more comprehensive approach to understanding how obesity alters daily biomechanical exposures within joint tissues may provide new insight into the protective and damaging effects of biomechanical factors on inflammation in osteoarthritis.", "title": "Pathobiology of obesity and osteoarthritis: integrating biomechanics and inflammation" }, { "docid": "MED-1641", "text": "Background Caffeine is one of the most widely consumed pharmacologically active substances. Its acute effect on myocardial blood flow is widely unknown. Our aim was to assess the acute effect of caffeine in a dose corresponding to two cups of coffee on myocardial blood flow (MBF) in coronary artery disease (CAD). Methodology/Principal Findings MBF was measured with 15O-labelled H2O and Positron Emission Tomography (PET) at rest and after supine bicycle exercise in controls (n = 15, mean age 58±13 years) and in CAD patients (n = 15, mean age 61±9 years). In the latter, regional MBF was assessed in segments subtended by stenotic and remote coronary arteries. All measurements were repeated fifty minutes after oral caffeine ingestion (200 mg). Myocardial perfusion reserve (MPR) was calculated as ratio of MBF during bicycle stress divided by MBF at rest. Resting MBF was not affected by caffeine in both groups. Exercise-induced MBF response decreased significantly after caffeine in controls (2.26±0.56 vs. 2.02±0.56, P<0.005), remote (2.40±0.70 vs. 1.78±0.46, P<0.001) and in stenotic segments (1.90±0.41 vs. 1.38±0.30, P<0.001). Caffeine decreased MPR significantly by 14% in controls (P<0.05 vs. baseline). In CAD patients MPR decreased by 18% (P<0.05 vs. baseline) in remote and by 25% in stenotic segments (P<0.01 vs. baseline).

Dental diseases impact considerably on self-esteem and quality of life and are expensive to treat. The objective of this paper is to review the evidence for an association between nutrition, diet and dental diseases and to present dietary recommendations for their prevention. Nutrition affects the teeth during development and malnutrition may exacerbate periodontal and oral infectious diseases. However, the most significant effect of nutrition on teeth is the local action of diet in the mouth on the development of dental caries and enamel erosion. Dental erosion is increasing and is associated with dietary acids, a major source of which is soft drinks. Despite improved trends in levels of dental caries in developed countries, dental caries remains prevalent and is increasing in some developing countries undergoing nutrition transition. There is convincing evidence, collectively from human intervention studies, epidemiological studies, animal studies and experimental studies, for an association between the amount and frequency of free sugars intake and dental caries. Although other fermentable carbohydrates may not be totally blameless, epidemiological studies show that consumption of starchy staple foods and fresh fruit are associated with low levels of dental caries. Fluoride reduces caries risk but has not eliminated dental caries and many countries do not have adequate exposure to fluoride. It is important that countries with a low intake of free sugars do not increase intake, as the available evidence shows that when free sugars consumption is <15-20 kg/yr ( approximately 6-10% energy intake), dental caries is low. For countries with high consumption levels it is recommended that national health authorities and decision-makers formulate country-specific and community-specific goals for reducing the amount of free sugars aiming towards the recommended maximum of no more than 10% of energy intake. In addition, the frequency of consumption of foods containing free sugars should be limited to a maximum of 4 times per day.

PATIENTS: 810 adult volunteers with prehypertension or stage 1 hypertension (systolic blood pressure, 120 to 159 mm Hg; diastolic blood pressure, 80 to 95 mm Hg). INTERVENTIONS: A multicomponent behavioral intervention that implemented long-established recommendations (\"established\"); a multicomponent behavioral intervention that implemented the established recommendations plus the Dietary Approaches to Stop Hypertension (DASH) diet (\"established plus DASH\"); and advice only. MEASUREMENTS: Lifestyle variables and blood pressure status. Follow-up for blood pressure measurement at 18 months was 94%. RESULTS: Compared with advice only, both behavioral interventions statistically significantly reduced weight, fat intake, and sodium intake. The established plus DASH intervention also statistically significantly increased fruit, vegetable, dairy, fiber, and mineral intakes.

Each clinical MGUS subtype is characterized by unique intermediate stages and progression events. Although we now have strong evidence that multiple myeloma is consistently preceded by a precursor state at the molecular level, there is urgent need to better understand mechanisms that regulate transformation from precursor to full-blown multiple myeloma. In the future, if such knowledge was available, it would allow clinicians to define high-risk and low-risk precursor patients for a more tailored clinical management. Also, it would provide insights on the individual patient's disease biology, which, in turn, can be used for targeted and more individualized treatment strategies. On the basis of current clinical guidelines, patients diagnosed with MGUS and smoldering myeloma should not be treated outside of clinical trials. In the near future, it seems reasonable to believe that high-risk precursor patients will likely become candidates for early treatment strategies.

The groups were matched for age and sex, and patients with hypercholesterolemia, diabetes mellitus, hypertension, and history of cigarette smoking were excluded. We also examined serum levels of C-reactive protein using an established high-sensitivity method. Subjects with advanced periodontal disease had lower flow-mediated dilation compared with control patients (7.8+/-4.6% versus 11.7+/-5.3%, P=0.005). Nitroglycerin-mediated dilation was equivalent in the two groups. Subjects with advanced periodontitis exhibited higher serum levels of high-sensitivity C-reactive protein compared with healthy controls patients (2.3+/-2.3 versus 1.0+/-1.0 mg/L, P=0.03).

The present studies were aimed at understanding the interaction of piperine with enzymatic drug biotransforming reactions in hepatic tissue in vitro and in vivo. Piperine inhibited arylhydrocarbon hydroxylation, ethylmorphine-N-demethylation, 7-ethoxycoumarin-O-deethylation and 3-hydroxy-benzo(a)pyrene glucuronidation in rat postmitochondrial supernatant in vitro in a dose-dependent manner. Piperine inhibition of these reactions in postmitochondrial supernatant from 3-methylcholanthrene- and phenobarbital-treated rats was similar to the controls. Inhibition by piperine of arylhydrocarbon hydroxylase (AHH) from 3-methylcholanthrene-treated rats was comparable to that observed with 7,8-benzoflavone. Piperine caused noncompetitive inhibition of hepatic microsomal AHH from the untreated and 3-methylcholanthrene-treated rats with a Ki of 30 microM which was close to the apparent Km of AHH observed in the controls. Similarly, the kinetics of inhibition of ethylmorphine-N-demethylase from control rat liver microsomes exhibited noncompetitive inhibition with an apparent Km of 0.8 mM and Ki of 35 microM. These studies demonstrated that piperine is a nonspecific inhibitor of drug metabolism which shows little discrimination between different cytochrome P-450 forms. Oral administration of piperine in rats strongly inhibited the hepatic AHH and UDP-glucuronyltransferase activities. The maximal inhibition of AHH observed within 1 hr restored to normal value in 6 hr.

Methods Chinese adults aged 25-45 years were randomly selected from a list of registered telephone numbers generated by computer. A telephone survey was administered to obtain information on demographic characteristics, dietary habits, dental visits, and knowledge of and presence of self-reported symptoms that can be related to dental erosion. Results A total of 520 participants were interviewed (response rate, 75%; sampling error, ± 4.4%) and their mean age was 37. Most respondents (79%) had ever had caries, and about two thirds (64%) attended dental check-ups at least once a year. Respondents had a mean of 5.4 meals per day and 36% had at least 6 meals per day. Fruit (89%) and lemon tea/water (41%) were the most commonly consumed acidic food and beverage. When asked if they ever noticed changes in their teeth, most respondents (92%) said they had experienced change that can be related to erosion. However, many (71%) had never heard about dental erosion and 53% mixed up dental erosion with dental caries.

In patients with coronary artery disease (CAD), caffeinated coffee increased caffeine serum concentration from 2 micromol/L to 23 micromol/L, coinciding with a significant increase in migratory activity of patient-derived EPCs. Decaffeinated coffee neither affected caffeine serum levels nor migratory capacity of EPCs. Treatment with caffeine for 7 to 10 days in a mouse-model improved endothelial repair after denudation of the carotid artery. The enhancement of reendothelialization by caffeine was significantly reduced in AMPK knockout mice compared to wild-type animals. Transplantation of wild-type and AMPK(-/-) bone marrow into wild-type mice revealed no difference in caffeine challenged reendothelialization. ECs which were depleted of mitochondrial DNA did not migrate when challenged with caffeine, suggesting a potential role for mitochondria in caffeine-dependent migration.

METHODS: A nationwide telephone survey of US households (N = 4051) was conducted between November 3, 2000, and February 12, 2001 to obtain a representative estimate of the self-reported incidence of non-influenza-related VRTI and related treatment patterns. Direct treatment costs measured included outpatient clinician encounters, use of over-the-counter and prescription drugs, and associated infectious complications of non-influenza-related VRTI. Absenteeism estimates for infected individuals and parents of infected children were extrapolated from National Health Interview Survey data. RESULTS: Of survey respondents, 72% reported a non-influenza-related VRTI within the past year. Respondents who experienced a self-reported non-influenza-related VRTI averaged 2.5 episodes annually. When these rates are extrapolated to the entire US population, approximately 500 million non-influenza-related VRTI episodes occur per year.

In conclusion, there is convincing evidence that plant foods and non-nutritive constituents associated with these foods modulate immunological and inflammatory processes. By means of anti-inflammatory activities a plant-based diet may contribute to the lower risk of cardiovascular diseases and cancer.

METHODS: Bag teas were purchased to represent black, green, citrus, fruity, and floral tea flavors from Tulsi, Bigelow, HyVee, Tazo, and Yogi brands and brewed (1 bag/240 ml) in boiling water for 3 minutes. The pH, titratable acidity, and fluoride concentrations were measured. Following these measurements, a representative tea from each flavor was selected for investigation of erosion potential. Six extracted human molars were randomly assigned to each tea. Teeth were painted with fingernail polish to expose a 1 x 4 mm window and then soaked in tea for a total of 25 hours with teas refreshed every 5 hours. Teeth were then sectioned using a microtome and photographed using a polarized light microscope. Lesion depths (i.e., eroded surfaces) were measured using Image Pro Plus software. Differences in physiochemical properties and lesion depths between beverages were investigated using one-way ANOVA with post-hoc Tukey's HSD test. Relationships among lesion depths and physiochemical properties were evaluated using the Pearson correlation test. RESULTS: pH, titratable acidity and fluoride concentrations differed between tea flavors (P < 0.05) and between brands (P < 0.05).

FMD of the brachial artery was measured before each intervention and 30, 90, and 120 min afterward. High-sensitivity C-reactive protein, interleukins 6 (Il-6) and 1b (Il-1b), total plasma antioxidative capacity, and total plasma oxidative status/stress were measured at baseline and at 120 min after each intervention. RESULTS: Resting and hyperemic brachial artery diameter did not change either with tea or with caffeine. FMD increased significantly with tea (by 3.69%, peak at 30 min, P<0.02), whereas it did not change significantly with caffeine (increase by 1.72%, peak at 30 min, P=NS).

Experimental introduction of high intakes of viscous fibers, vegetable proteins and plant sterols in the form of a possible Myocene diet of leafy vegetables, fruit and nuts, lowered serum LDL-cholesterol in healthy volunteers by over 30%, equivalent to first generation statins, the standard cholesterol-lowering medications. Furthermore, supplementation of a modern therapeutic diet in hyperlipidemic subjects with the same components taken as oat, barley and psyllium for viscous fibers, soy and almonds for vegetable proteins and plant sterol-enriched margarine produced similar reductions in LDL-cholesterol as the Myocene-like diet and reduced the majority of subjects' blood lipids concentrations into the normal range. We conclude that reintroduction of plant food components, which would have been present in large quantities in the plant based diets eaten throughout most of human evolution into modern diets can correct the lipid abnormalities associated with contemporary eating patterns and reduce the need for pharmacological interventions.", "title": "The Garden of Eden--plant based diets, the genetic drive to conserve cholesterol and its implications for heart disease in the 21st century." }, { "docid": "MED-3639", "text": "Several foods have been shown to contain natural components (especially polyphenols) which display anti-adhesive properties against Streptococcus mutans, the aetiological agent responsible for dental crown caries, as well as inhibition of glucosyltransferases, which are the S. mutans enzymes involved in the synthesis of an adherent, water-insoluble glucan from sucrose.

The effectiveness of gargling for preventing URTI has been shown in a randomized controlled trial that compared incidences of URTI between gargling and control groups. From the perspective of the third-party payer, gargling is dominant due to the fact that the costs of gargling are borne by the participant. However, the cost-effectiveness of gargling from a societal perspective should be considered. In this study, economic evaluation alongside a randomized controlled trial was performed to evaluate the cost-effectiveness of gargling for preventing URTI from a societal perspective. Methods Among participants in the gargling trial, 122 water-gargling and 130 control subjects were involved in the economic analysis. Sixty-day cumulative follow-up costs and effectiveness measured by quality-adjusted life days (QALD) were compared between groups on an intention-to-treat basis. Incremental cost-effectiveness ratio (ICER) was converted to dollars per quality-adjusted life years (QALY). The 95% confidence interval (95%CI) and probability of gargling being cost-effective were estimated by bootstrapping. Results After 60 days, QALD was increased by 0.43 and costs were $37.1 higher in the gargling group than in the control group. ICER of the gargling group was $31,800/QALY (95%CI, $1,900–$248,100). Although this resembles many acceptable forms of medical intervention, including URTI preventive measures such as influenza vaccination, the broad confidence interval indicates uncertainty surrounding our results. In addition, one-way sensitivity analysis also indicated that careful evaluation is required for the cost of gargling and the utility of moderate URTI. The major limitation of this study was that this trial was conducted in winter, at a time when URTI is prevalent. Care must be taken when applying the results to a season when URTI is not prevalent, since the ICER will increase due to decreases in incidence.

DESIGN: Prospective, observational study. SETTING: Greater Boston, Massachusetts, metropolitan area. PARTICIPANTS: Six hundred twenty-five community-dwelling men participating in the Department of Veterans Affairs Dental Longitudinal Study. MEASUREMENTS: Dental and physical examinations were conducted every 3 to 5 years. Diet was assessed using food frequency questionnaires (FFQs). Mean follow-up was 15 years (range: 2-24 years). Periodontal disease progression on each tooth was defined as alveolar bone loss (ABL) advancement of 40% or more, probing pocket depth (PPD) of 2 mm or more, or tooth loss. Good and excellent fiber sources provided 2.5 g or more of fiber per serving. Multivariate proportional hazards regression estimated hazard ratios (HRs) and 95% confidence intervals (CIs) of periodontal disease progression and tooth loss in relation to fiber sources, stratified according to age younger than 65 versus 65 and older, and controlled for smoking, body mass index, calculus, baseline periodontal disease level, caries, education, exercise, carotene, thiamin and caffeine intake, and tooth brushing. RESULTS: In men aged 65 and older, each serving of good to excellent sources of total fiber was associated with lower risk of ABL progression (HR = 0.76, 95% CI = 0.60-0.95) and tooth loss (HR = 0.72, 95% CI = 0.53-0.97).

A study was undertaken to examine whether this discrepancy could be attributed to a high consumption of fresh fruit and vegetables or adherence to a traditional Mediterranean diet. Methods A cross‐sectional survey was performed in 690 children aged 7–18 years in rural Crete. Parents completed a questionnaire on their child's respiratory and allergic symptoms and a 58‐item food frequency questionnaire. Adherence to a Mediterranean diet was measured using a scale with 12 dietary items. Children underwent skin prick tests with 10 common aeroallergens. Results 80% of children ate fresh fruit (and 68% vegetables) at least twice a day. The intake of grapes, oranges, apples, and fresh tomatoes—the main local products in Crete—had no association with atopy but was protective for wheezing and rhinitis. A high consumption of nuts was found to be inversely associated with wheezing (OR 0.46; 95% CI 0.20 to 0.98), whereas margarine increased the risk of both wheeze (OR 2.19; 95% CI 1.01 to 4.82) and allergic rhinitis (OR 2.10; 95% CI 1.31 to 3.37).

However, there is growing evidence that certain practical nutritional measures have the potential to slow tumor angiogenesis, and it is reasonable to anticipate that, by combining several measures that work in distinct but complementary ways to impede the angiogenic process, a clinically useful 'multifocal angiostatic therapy' (MAT) might be devised. Several measures which might reasonably be included in such a protocol are discussed below, and include: a low-fat, low-glycemic index vegan diet, which may down-regulate the systemic IGF-I activity that supports angiogenesis; supplemental omega-3-rich fish oil, which has been shown to inhibit endothelial expression of Flk-1, a functionally crucial receptor for VEGF, and also can suppress tumor production of pro-angiogenic eicosanoids; high-dose selenium, which has recently been shown to inhibit tumor production of VEGF; green tea polyphenols, which can suppress endothelial responsiveness to both VEGF and fibroblast growth factor; and high-dose glycine, whose recently reported angiostatic activity may reflect inhibition of endothelial cell mitosis, possibly mediated by activation of glycine-gated chloride channels. In light of evidence that tumor-evoked angiogenesis has a high requirement for copper, copper depletion may have exceptional potential as an angiostatic measure, and is most efficiently achieved with the copper-chelating drug tetrathiomolybdate. If logistical difficulties make it difficult to acquire this experimental drug, high-dose zinc supplementation can achieve a slower depletion of the body's copper pool, and in any case can be used as maintenance therapy to maintain an adequate level of copper depletion. A provisional protocol is offered for a nutritionally based MAT entailing a vegan diet and supplemental intakes of fish oil, selenium, green tea polyphenols, glycine, and zinc.

This investigation evaluates the structural effect that stinging nettle spicules may have on the clinical manifestation of these symptoms. This hypothesis was investigated by exposing murine skin to stinging nettles and then evaluating the skin using electron microscopy. It was hypothesized that the mechanism of action of stinging nettles is both biochemical and mechanical, which may have clinical significance regarding treatment for acute exposure. METHODS: Fresh post-mortem dermis samples from the carcasses of genetically modified hairless mice were brushed under the stem and leaf of a stinging nettle plant, mimicking the clinical method of exposure a patient might experience. Another set of mouse skin samples was obtained but not exposed to the nettles. Both sets of skin samples were imaged with scanning electron microscopy. RESULTS: The skin samples that were not exposed to nettle leaves were uniform, with occasional striated hairs on the skin surface and no nettle spicules. The skin samples exposed to nettle leaves showed many smooth nettle spicules piercing the skin surface. A few spicules retained their bases, which appear empty of any liquid contents. CONCLUSIONS: The mechanism of action of stinging nettles dermatitis appears to be both biochemical and mechanical.

Isometric strength recovered significantly faster (P=0.024) in the cherry juice group. No other damage indices were significantly different. Inflammation was reduced in the cherry juice group (IL-6, P<0.001; CRP, P<0.01; uric acid, P<0.05). TAS was ~10% greater in the cherry juice than the placebo group for all post-supplementation measures (P<0.05). Protein carbonyls was not different; however, TBARS was lower in the cherry juice than the placebo at 48 h (P<0.05). The cherry juice appears to provide a viable means to aid recovery following strenuous exercise by increasing total antioxidative capacity, reducing inflammation, lipid peroxidation and so aiding in the recovery of muscle function. © 2009 John Wiley & Sons A/S.", "title": "Influence of tart cherry juice on indices of recovery following marathon running." }, { "docid": "MED-2807", "text": "In a previous three-month study of Meriva, a proprietary curcumin-phosphatidylcholine phytosome complex, decreased joint pain and improvement in joint function were observed in 50 osteoarthritis (OA) patients.

Alzheimer's disease (AD) is the most prevalent neurodegenerative disease of the elderly and is characterized by regional specificity of neural aberrations associated with higher cognitive functions. Aluminum (Al) is the most abundant neurotoxic metal on earth, widely bioavailable to humans and repeatedly shown to accumulate in AD-susceptible neuronal foci. In spite of this, the role of Al in AD has been heavily disputed based on the following claims: 1) bioavailable Al cannot enter the brain in sufficient amounts to cause damage, 2) excess Al is efficiently excreted from the body, and 3) Al accumulation in neurons is a consequence rather than a cause of neuronal loss. Research, however, reveals that: 1) very small amounts of Al are needed to produce neurotoxicity and this criterion is satisfied through dietary Al intake, 2) Al sequesters different transport mechanisms to actively traverse brain barriers, 3) incremental acquisition of small amounts of Al over a lifetime favors its selective accumulation in brain tissues, and 4) since 1911, experimental evidence has repeatedly demonstrated that chronic Al intoxication reproduces neuropathological hallmarks of AD. Misconceptions about Al bioavailability may have misled scientists regarding the significance of Al in the pathogenesis of AD. The hypothesis that Al significantly contributes to AD is built upon very solid experimental evidence and should not be dismissed.

OA used to be considered the sole consequence of any process leading to increased pressure on one particular joint or fragility of cartilage matrix. Progress in molecular biology in the 1990s has profoundly modified this paradigm. The discovery that many soluble mediators such as cytokines or prostaglandins can increase the production of matrix metalloproteinases by chondrocytes led to the first steps of an \"inflammatory\" theory. However, it took a decade before synovitis was accepted as a critical feature of OA, and some studies are now opening the way to consider the condition a driver of the OA process. Recent experimental data have shown that subchondral bone may have a substantial role in the OA process, as a mechanical damper, as well as a source of inflammatory mediators implicated in the OA pain process and in the degradation of the deep layer of cartilage. Thus, initially considered cartilage driven, OA is a much more complex disease with inflammatory mediators released by cartilage, bone and synovium. Low-grade inflammation induced by the metabolic syndrome, innate immunity and inflammaging are some of the more recent arguments in favor of the inflammatory theory of OA and highlighted in this review.

METHODS AND RESULTS: High frequency ultrasound was used to measure blood flow and percentage brachial artery dilatation after reactive hyperaemia induced by forearm cuff occlusion in 12 healthy subjects, less than 40 years of age, without known cardiovascular risk factors. The subjects drank 250 ml of red wine with or without alcohol over 10 min according to a randomized procedure. Brachial artery dilatation was measured again 30 and 60 min after the subjects had finished drinking. The subjects were studied a second time within a week of the first study in a cross-over design. After the red wine with alcohol the resting brachial artery diameter, resting blood flow, heart rate and plasma-ethanol increased significantly. After the de-alcoholized red wine these parameters were unchanged. Flow-mediated dilatation of the brachial artery was significantly higher (P<0.05) after drinking de-alcoholized red wine (5.6+/-3.2%) than after drinking red wine with alcohol (3.6+/-2.2%) and before drinking (3.9+/-2.5%). CONCLUSION: After ingestion of red wine with alcohol the brachial artery dilated and the blood flow increased. These changes were not observed following the de-alcoholized red wine and were thus attributable to ethanol. These haemodynamic changes may have concealed an effect on flow-mediated brachial artery dilatation which did not increase after drinking red wine with alcohol. Flow-mediated dilatation of the brachial artery increased significantly after de-alcoholized red wine and this finding may support the hypothesis that antioxidant qualities of red wine, rather than ethanol in itself, may protect against cardiovascular disease.

The antioxidant status of the plasma samples was also measured through several complementary antioxidant techniques. High-performance liquid chromatography coupled to time-of-flight mass spectrometry (HPLC-ESI-TOF-MS) was used for the bioavailability study.

Although phenolic acids were found in plasma without any modification in their structures, most flavonols were found as quercetin or kaempferol glucuronide conjugates. Flavonol glucuronide conjugates, which show longer half-life elimination values, are proposed to contribute to the observed lipid peroxidation inhibitory activity in the cellular membranes. By contrast, phenolic acids appear to exert their antioxidant activity through ferric ion reduction and superoxide scavenging at shorter times.

HS decoctions and infusions of calyxes, and on occasion leaves, are used in at least 10 countries worldwide in the treatment of hypertension and hyperlipidemia with no reported adverse events or side effects. HS extracts have a low degree of toxicity with a LD50 ranging from 2,000 to over 5,000 mg/kg/day. There is no evidence of hepatic or renal toxicity as the result of HS extract consumption, except for possible adverse hepatic effects at high doses. There is evidence that HS acts as a diuretic, however in most cases the extract did not significantly influence electrolyte levels. Animal studies have consistently shown that consumption of HS extract reduces blood pressure in a dose dependent manner. In RCTs, the daily consumption of a tea or extract produced from HS calyxes significantly lowered systolic blood pressure (SBP) and diastolic blood pressure (DBP) in adults with pre to moderate essential hypertension and type 2 diabetes. In addition, HS tea was as effective at lowering blood pressure as the commonly used blood pressure medication Captropril, but less effective than Lisinopril. Total cholesterol, low-density lipoprotein cholesterol (LDL-C), and triglycerides were lowered in the majority of normolipidemic, hypolipidemic, and diabetic animal models, whereas high-density lipoprotein cholesterol (HDL-C) was generally not affected by the consumption of HS extract. Over half of the RCTs showed that daily consumption of HS tea or extracts had favorable influence on lipid profiles including reduced total cholesterol, LDL-C, triglycerides, as well as increased HDL-C. Anthocyanins found in abundance in HS calyxes are generally considered the phytochemicals responsible for the antihypertensive and hypocholesterolemic effects, however evidence has also been provided for the role of polyphenols and hibiscus acid. A number of potential mechanisms have been proposed to explain the hypotensive and anticholesterol effects, but the most common explanation is the antioxidant effects of the anthocyanins inhibition of LDL-C oxidation, which impedes atherosclerosis, an important cardiovascular risk factor.

METHODS: Changes in plasma AOC following consumption of a single meal of berries/fruits (blueberry, dried plum, dried plum juice, grape, cherry, kiwifruit and strawberry) were studied in 5 clinical trials with 6-10 subjects per experiment. In two studies with blueberry or grape, additional macronutrients (carbohydrate, fat, protein) were included in the control and treatment meals. Blood samples collected before and after the meal were analyzed for AOC. RESULTS: Consumption of dried plums or dried plum juice did not alter either the H- or L-AOC area under the curve (AUC). Consumption of blueberry in 2 studies and of mixed grape powder [12.5 (Study #1), 39.9 (Study #4) and 8.6 (Study #5) mmole Trolox Equivalents (TE) AOC, respectively] increased hydrophilic AOC AUC. L-AOC increased following a meal of blueberry containing 12.5 mmole TE AOC (Study #1). Consumption of 280 g of cherries (4.5 mmol TE AOC) increased plasma L-AOC but not H-AOC. The AOC in the control groups in which additional macronutrients (Studies #4 and #5) were added decreased from the postprandial baseline AOC measurement. CONCLUSION: We have demonstrated that consumption of certain berries and fruits such as blueberries, mixed grape and kiwifruit, was associated with increased plasma AOC in the postprandial state and consumption of an energy source of macronutrients containing no antioxidants was associated with a decline in plasma AOC.

We found that NF-kappaB was constitutively active in all human MM cell lines examined and that curcumin, a chemopreventive agent, down-regulated NF-kappaB in all cell lines as indicated by electrophoretic mobility gel shift assay and prevented the nuclear retention of p65 as shown by immunocytochemistry. All MM cell lines showed consitutively active IkappaB kinase (IKK) and IkappaBalpha phosphorylation. Curcumin suppressed the constitutive IkappaBalpha phosphorylation through the inhibition of IKK activity. Curcumin also down-regulated the expression of NF-kappaB-regulated gene products, including IkappaBalpha, Bcl-2, Bcl-x(L), cyclin D1, and interleukin-6. This led to the suppression of proliferation and arrest of cells at the G(1)/S phase of the cell cycle. Suppression of NF-kappaB complex by IKKgamma/NF-kappaB essential modulator-binding domain peptide also suppressed the proliferation of MM cells. Curcumin also activated caspase-7 and caspase-9 and induced polyadenosine-5'-diphosphate-ribose polymerase (PARP) cleavage. Curcumin-induced down-regulation of NF-kappaB, a factor that has been implicated in chemoresistance, also induced chemosensitivity to vincristine and melphalan. Overall, our results indicate that curcumin down-regulates NF-kappaB in human MM cells, leading to the suppression of proliferation and induction of apoptosis, thus providing the molecular basis for the treatment of MM patients with this pharmacologically safe agent.", "title": "Curcumin (diferuloylmethane) down-regulates the constitutive activation of nuclear factor-kappa B and IkappaBalpha kinase in human multiple myeloma..." }, { "docid": "MED-4024", "text": "We reviewed data from six cohort studies and approximately 40 case-control studies on the relation between selected aspects of diet and the risk of oral and pharyngeal cancer.

Magnetic resonance imaging studies of AD clinical progression have confirmed general conclusions from earlier studies of AD neuropathological progression wherein neurofibrillary tangle pathology was observed to spread along a well-defined sequence of corticocortical and corticosubcortical connections, preferentially affecting certain cell types, while sparing others. Identical and non-identical twin studies have consistently shown AD has mixed (environmental and genetic) etiopathogenesis.

Major environmental candidates are reviewed to assess which best fits the profile of an agent that slowly accrues in susceptible cell types of AD-vulnerable brain regions to toxic levels by old age, giving rise to AD neuropathology without rapid neuronal lysis. Chronic aluminum neurotoxicity best matches this profile. Many humans routinely ingest aluminum salts as additives contained in processed foods and alum-treated drinking water. The physical properties of aluminum and ferric iron ions are similar, allowing aluminum to use mechanisms evolved for iron to enter vulnerable neurons involved in AD progression, accumulate in those neurons, and cause neurofibrillary damage. The genetic component of AD etiopathogenesis apparently involves a susceptibility gene, yet to be identified, that increases aluminum absorption because AD and Down syndrome patients have higher than normal plasma, and brain, aluminum levels.

Methods Twelve healthy male students every day consumed one 500 ml bottle of mineral water, containing 0.05 ml peppermint essential oil for ten days. Blood pressure, heart rate, and spirometry parameters including forced vital capacity (FVC), peak expiratory flow rate (PEF), and peak inspiratory flow (PIF) were determined one day before, and after the supplementation period. Participants underwent a treadmill-based exercise test with metabolic gas analysis and ventilation measurement using the Bruce protocol. Results The FVC (4.57 ± 0.90 vs. 4.79 ± 0.84; p < 0.001), PEF (8.50 ± 0.94 vs. 8.87 ± 0.92; p < 0.01), and PIF (5.71 ± 1.16 vs. 6.58 ±1.08; p < 0.005) significantly changed after ten days of supplementation.

Direct effects of tea components on the vasculature, particularly the endothelium, may partly explain this association. Objective We performed a meta-analysis of controlled human intervention studies on the effect of tea on flow-mediated dilation (FMD) of the brachial artery, a measurement of endothelial function, which is suggested to be associated with cardiovascular risk. Methods Human intervention studies were identified by systematic search of the databases Medline, Embase, Chemical s and Biosis through March 2009 and by hand-searching related articles. Studies were selected based on predefined criteria: intervention with tea as the sole experimental variable, placebo-controlled design, and no missing data on FMD outcome or its variability. A random effects model was used to calculate the pooled overall effect on FMD due to the intake of tea. The impact of various subject and treatment characteristics was investigated in the presence of heterogeneity. Results In total, 9 studies from different research groups were included with 15 relevant study arms. The overall absolute increase in FMD of tea vs. placebo was 2.6% of the arterial diameter (95% CI: 1.8-3.3%; P-value <0.001) for a median daily dose of 500 mL of tea (2–3 cups). This is a relative increase of approximately 40% compared to the average FMD of 6.3% measured under placebo or baseline conditions. There was significant heterogeneity between studies (P-value <0.001) that might partly be explained by the cuff position either distal or proximal to the area of FMD measurement.

MATERIALS AND METHODS: The effect of different camel urines, compared to bovine urines, on Cyp1a1 mRNA was determined using real-time polymerase chain reaction. Cyp1a1 protein and catalytic activity levels were determined using Western blot analysis and 7-ethoxyresorufin as a substrate, respectively. The role of aryl hydrocarbon receptor (AhR)-dependent mechanism was determined using electrophoretic mobility shift assay (EMSA) and the AhR-dependent luciferase reporter gene. RESULTS: All types of camel, but not bovine, urines differentially inhibited the induction of Cyp1a1 gene expression by TCDD, the most potent Cyp1a1 inducer and known carcinogenic chemical. Importantly, virgin camel urine showed the highest degree of inhibition at the activity level, followed by lactating and pregnant camel urines. Furthermore, we have shown that virgin camel urine significantly inhibited the TCDD-mediated induction of Cyp1a1 at the mRNA and protein expression levels. Mechanistically, the ability of virgin camel urine to inhibit Cyp1a1 was strongly correlated with its ability to inhibit AhR-dependent luciferase activity and DNA binding as determined by EMSA, suggesting that AhR-dependent mechanism is involved. CONCLUSIONS: The present work provides the first evidence that camel urine but not that of bovine inhibits the TCDD-mediated toxic effect by inhibiting the expression of Cyp1a1, at both transcriptional and post-transcriptional levels through an AhR-dependent mechanism.

In addition, the mechanisms by which green tea intake may influence risk of breast cancer in humans remains not well studied. We review the human studies that have evaluated the relationship between green tea intake and four biomarkers (sex steroid hormones, mammographic density, insulin-like growth factor, adiponectin) that are believed to be important in breast cancer development.

At this meeting, there was a discussion of important updates on human papillomavirus (HPV), genital warts, and cervical cancer screening. METHODS: Key questions were identified with assistance from an expert panel, and systematic reviews of the literature were conducted searching the English-language literature of the PubMed computerized database (US National Library of Medicine). The available evidence was reviewed, and new information was incorporated in the 2010 CDC STD Treatment Guidelines. RESULTS: Two HPV vaccines are now available, the quadrivalent HPV vaccine and the bivalent HPV vaccine; either vaccine is recommended routinely for girls aged 11 or 12 years. The quadrivalent HPV vaccine may be given to boys and men aged 9-26 years. A new patient-applied treatment option for genital warts, sinecatechins 15% ointment, is available and recommended for treatment of external genital warts. This product is a mixture of active ingredients (catechins) from green tea. Finally, updated counseling guidelines and messages about HPV, genital warts, and cervical cancer are included. CONCLUSIONS: This manuscript highlights updates to the 2010 CDC STD Treatment Guidelines for HPV and genital warts.

However, exercise also increases mitochondrial formation of presumably harmful reactive oxygen species (ROS). Antioxidants are widely used as supplements but whether they affect the health-promoting effects of exercise is unknown. We evaluated the effects of a combination of vitamin C (1000 mg/day) and vitamin E (400 IU/day) on insulin sensitivity as measured by glucose infusion rates (GIR) during a hyperinsulinemic, euglycemic clamp in previously untrained (n = 19) and pretrained (n = 20) healthy young men. Before and after a 4 week intervention of physical exercise, GIR was determined, and muscle biopsies for gene expression analyses as well as plasma samples were obtained to compare changes over baseline and potential influences of vitamins on exercise effects. Exercise increased parameters of insulin sensitivity (GIR and plasma adiponectin) only in the absence of antioxidants in both previously untrained (P < 0.001) and pretrained (P < 0.001) individuals. This was paralleled by increased expression of ROS-sensitive transcriptional regulators of insulin sensitivity and ROS defense capacity, peroxisome-proliferator-activated receptor gamma (PPARγ), and PPARγ coactivators PGC1α and PGC1β only in the absence of antioxidants (P < 0.001 for all). Molecular mediators of endogenous ROS defense (superoxide dismutases 1 and 2; glutathione peroxidase) were also induced by exercise, and this effect too was blocked by antioxidant supplementation. Consistent with the concept of mitohormesis, exercise-induced oxidative stress ameliorates insulin resistance and causes an adaptive response promoting endogenous antioxidant defense capacity.

A third group ingested 50 g of soy and 3 g of green tea daily, and the control group had a hypocholesterolemic diet. Evaluations were performed at baseline and after 45 and 90 d. Plasma levels of total cholesterol, high-density lipoprotein, and triacylglycerols were evaluated by automated methods. Low-density lipoprotein (LDL) cholesterol was calculated using the Friedewald equation. LDL was isolated by ultracentrifugation. Total plasma antioxidant capacity and plasma levels of total lipid hydroperoxides and those linked to LDL were evaluated by chemiluminescence. The results were expressed as median values and their 25th to 75th percentiles, with a 5% level of significance. RESULTS: No significant difference occurred in LDL, high-density lipoprotein cholesterol, and triacylglycerol levels across groups.

The most abundant HCA found in the human diet is 2-amino-1-methyl-6-phenylimidazo[4,5-b] pyridine (PhIP). PhIP causes mammary carcinomas in female rats and mice, and is associated with an increased risk of developing colon, breast, and prostate cancer in humans. PhIP is metabolized by cytochrome P-450s producing N-OH-PhIP. The N-OH-PhIP can be esterified by phase II enzymes forming an arylnitrenium ion that binds to DNA causing adducts. Furthermore, N-OH-PhIP may be reduced by cytochrome b5 reductase producing superoxide anions and hydroxyl radicals causing DNA strand breaks. Diallyl sulfide (DAS) has been shown to prevent cancer in several animal models, presumably by metabolic modulation. We hypothesize that PhIP produces reactive oxygen species causing DNA strand breaks and that DAS will inhibit the formation of PhIP induced DNA strand breaks. To test this hypothesis we treated normal breast epithelial (MCF-10A) cells with PhIP, DAS and a combination of PhIP and DAS. The detection of lipid peroxides was used as a surrogate for ROS. Lipid peroxides were detected using a PeroxiDetect kit (Sigma). PhIP increased the production of lipid peroxides and DAS decreased the PhIP-induced peroxidation by 47%. To determine if PhIP causes DNA strand breaks in MCF-10A cells, cells were treated for 3, 6, 9, and 24 h with PhIP (100 microM), DAS (100 microM) and a combination of PhIP (100 microM) and DAS (100 microM).

In men, the multivariate-adjusted ORs for tooth loss with a cut-off point of <20 teeth associated with different frequencies of green tea consumption were 1.00 (reference) for <1 cup/day, 0.82 (95% CI, 0.74-0.91) for 1-2 cups/day, 0.82 (95% CI, 0.73-0.92) for 3-4 cups/day, and 0.77 (95% CI, 0.66-0.89) for > or = 5 cups/day.

We collected detailed information on occupational history and assessed exposure to meat in general and several types of meat via expert assessment of the questionnaires. The odds ratio (OR) of non-Hodgkin lymphoma for ever occupational exposure to meat was 1.18 (95% confidence interval [CI] 0.95-1.46), that for exposure to beef meat was 1.22 (95% CI 0.90-1.67), and that for exposure to chicken meat was 1.19 (95% CI 0.91-1.55). The ORs were higher among workers with longer duration of exposure. An increased risk among workers exposed to beef meat was mainly apparent for diffuse large B-cell lymphoma (OR 1.49, 95%CI 0.96-2.33), chronic lymphocytic leukemia (OR 1.35, 95% CI 0.78-2.34) and multiple myeloma (OR 1.40, 95%CI 0.67-2.94).

PARTICIPANTS: Healthy volunteers (387) aged 18 to 65 years. INTERVENTION: Participants were randomly assigned to water gargling, povidone-iodine gargling, and usual care (control). Subjects in the two gargling groups were requested to gargle with water or diluted povidone-iodine at least three times a day. Participants were followed for 60 days. MAIN OUTCOME MEASURES: The primary outcome measure was first URTI incidence. Severity of URTI symptoms among incident cases was also evaluated. Both outcomes were assessed with a self-administered symptom record. Analyses were performed on an intention-to-treat basis. RESULTS: A total of 130 participants contracted URTIs. The incidence rate of first URTI was 0.26 episodes/30 person-days among control subjects. The rate decreased to 0.17 episodes/30 person-days in the water gargling group, and 0.24 episodes/30 person-days in the povidone-iodine gargling group.

Dietary plants contain variable chemical families and amounts of antioxidants. It has been hypothesized that plant antioxidants may contribute to the beneficial health effects of dietary plants. Our objective was to develop a comprehensive food database consisting of the total antioxidant content of typical foods as well as other dietary items such as traditional medicine plants, herbs and spices and dietary supplements. This database is intended for use in a wide range of nutritional research, from in vitro and cell and animal studies, to clinical trials and nutritional epidemiological studies. Methods We procured samples from countries worldwide and assayed the samples for their total antioxidant content using a modified version of the FRAP assay. Results and sample information (such as country of origin, product and/or brand name) were registered for each individual food sample and constitute the Antioxidant Food Table. Results The results demonstrate that there are several thousand-fold differences in antioxidant content of foods. Spices, herbs and supplements include the most antioxidant rich products in our study, some exceptionally high. Berries, fruits, nuts, chocolate, vegetables and products thereof constitute common foods and beverages with high antioxidant values. Conclusions This database is to our best knowledge the most comprehensive Antioxidant Food Database published and it shows that plant-based foods introduce significantly more antioxidants into human diet than non-plant foods. Because of the large variations observed between otherwise comparable food samples the study emphasizes the importance of using a comprehensive database combined with a detailed system for food registration in clinical and epidemiological studies.

This chemopreventive effect is related to the high content of these foods in phytochemicals, such as polyphenols, that interfere with several processes involved in cancer progression including tumor cell growth, survival and angiogenesis. In addition to the low intake of plant-based foods, increased body mass and physical inactivity have recently emerged as other important lifestyle factors influencing cancer risk, leading to the generation of low-grade chronic inflammatory conditions which are a key process involved in tumor progression. The objectives of the current study are to investigate the inhibitory effects of these polyphenols on angiogenesis triggered by an inflammatory cytokine (IL-6) and to determine the mechanisms underlying this action. We found that, among the tested polyphenols, apigenin and luteolin were the most potent angiogenesis inhibitors through their inhibitory effect on the inflammatory cytokine IL-6/STAT3 pathway. These effects resulted in modulation of the activation of extracellular signal-regulated kinase-1/2 signaling triggered by IL-6, as well as in a marked reduction in the proliferation, migration and morphogenic differentiation of endothelial cells. Interestingly, these polyphenols also modulated the expression of IL-6 signal transducing receptor (IL-6Rα) and the secretion of the extracellular matrix degrading enzyme MMP-2 as well as the expression of suppressor of cytokine signaling (SOCS3) protein.

Recent advances have indicated that the liver-derived peptide hepcidin plays a central role in this process by repressing iron release from intestinal enterocytes, macrophages and other body cells. When iron requirements are increased, hepcidin levels decline and more iron enters the plasma. It has been proposed that the level of circulating diferric transferrin, which reflects tissue iron levels, acts as a signal to alter hepcidin expression. In the liver, the proteins HFE, transferrin receptor 2 and hemojuvelin may be involved in mediating this signal as disruption of each of these molecules decreases hepcidin expression. Patients carrying mutations in these molecules or in hepcidin itself develop systemic iron loading (or hemochromatosis) due to their inability to down regulate iron absorption. Hepcidin is also responsible for the decreased plasma iron or hypoferremia that accompanies inflammation and various chronic diseases as its expression is stimulated by pro-inflammatory cytokines such as interleukin 6.

Sensitization to a normally harmless allergen results in the immune system being biased to a predominant T-helper type 2 response. Re-exposure to the same allergen leads to a robust secretion of allergy-related mediators that eventually triggers symptoms. Our understanding of these disorders has enabled the search of therapeutic approaches that can either modulate the sensitization process or impact on allergic mediators, thus helping manage allergic symptoms. Polyphenols are one such class of compounds that are found in foods and plant sources and have been investigated for their anti-allergic effect in different disease models and in human clinical trials. Their anti-inflammatory profile is known to impact on the recruitment of immune cells to the skin and in preventing the development of secondary infections following disruption of the skin barrier. The interaction of polyphenols with proteins can modulate the process of allergic sensitization and their direct effect on allergic effector cells such as mast cells inhibit mediator release, resulting in the alleviation of symptoms. In addition, their endogenous anti-oxidant ability limits the extent of cellular injury from free radicals during the allergic insult.

Nevertheless, exercise-derived ROS are essential to regulate cellular adaptation to exercise. Studies on antioxidant supplements have provided controversial results. The purpose of this study was to determine the effect of moderate antioxidant supplementation (lemon verbena extract) in healthy male volunteers that followed a 90-min running eccentric exercise protocol for 21 days. Antioxidant enzymes activities and oxidative stress markers were measured in neutrophils. Besides, inflammatory cytokines and muscular damage were determined in whole blood and serum samples, respectively. Intense running exercise for 21 days induced antioxidant response in neutrophils of trained male through the increase of the antioxidant enzymes catalase, glutathione peroxidase and glutathione reductase. Supplementation with moderate levels of an antioxidant lemon verbena extract did not block this cellular adaptive response and also reduced exercise-induced oxidative damage of proteins and lipids in neutrophils and decreased myeloperoxidase activity. Moreover, lemon verbena supplementation maintained or decreased the level of serum transaminases activity indicating a protection of muscular tissue. Exercise induced a decrease of interleukin-6 and interleukin-1β levels after 21 days measured in basal conditions, which was not inhibited by antioxidant supplementation.

Recent research in Turkey has shown that spearmint tea has antiandrogenic properties in females with hirsutism. No research has yet been undertaken to assess whether a reduction in androgen levels brought about by spearmint tea, translates to a clinical improvement in the degree of hirsutism. This study was a two centre, 30 day randomized controlled trial. Forty two volunteers were randomized to take spearmint tea twice a day for a 1 month period and compared with a placebo herbal tea. At 0, 15 and 30 days of the study serum androgen hormone levels and gonadotrophins were checked, the degree of hirsutism was clinically rated using the Ferriman-Galwey score and a questionnaire (the modified DQLI = Dermatology Quality of Life Index) was used to assess improvements in the level of self-reported hirsutism. Forty one of 42 patients completed the study. Free and total testosterone levels were significantly reduced over the 30 day period in the spearmint tea group (p < 0.05). LH and FSH also increased (p < 0.05). Patient's subjective assessments of their degree of hirsutism scored by the modified DQLI were significantly reduced in the spearmint tea group (p < 0.05). There was, however, no significant reduction in the objective Ferriman-Galwey ratings of hirsutism between the two trial groups over the trial duration (p = 0.12). There was a clear and significant alteration in the relevant hormone levels. This is associated clinically with a reduction in the self-reported degree of hirsutism but unfortunately not with the objectively rated score. It was demonstrated and confirmed that spearmint has antiandrogen properties, the simple fact that this does not clearly translate into clinical practice is due to the relationship between androgen hormones and follicular hair growth and cell turnover time. Simply put, the study duration was not long enough. The original studies from Turkey were in fact only 5 days long. The time taken for hirsutism to resolve is significant and a much longer future study is proposed as the preliminary findings are encouraging that spearmint has the potential for use as a helpful and natural treatment for hirsutism in PCOS.

DESIGN: Asthmatic adults (n = 137) were randomly assigned to a high-antioxidant diet (5 servings of vegetables and 2 servings of fruit daily; n = 46) or a low-antioxidant diet (≤2 servings of vegetables and 1 serving of fruit daily; n = 91) for 14 d and then commenced a parallel, randomized, controlled supplementation trial. Subjects who consumed the high-antioxidant diet received placebo. Subjects who consumed the low-antioxidant diet received placebo or tomato extract (45 mg lycopene/d).

There are important practical differences between the development of public health nutrition guidelines and guidelines for clinical practice. While the gold standard for evidence for clinical practice guidelines is a meta-analysis of a number of randomised controlled trials, this is often unrealistic and sometimes unethical for the evaluation of public health nutrition interventions. Hence, epidemiological studies make up the bulk of evidence for nutrition guidelines. Tea and coffee are an interesting case study in relation to this issue. They are two of the most commonly consumed beverages worldwide, yet there is little dietary advice on their use. The evidence for a relationship between coffee or tea consumption and several diseases is discussed. The available studies, predominantly epidemiological, together with animal and in vitro studies, indicate that coffee and tea are both safe beverages. However, tea is the healthier option because it has a possible role in the prevention of several cancers and CVD. While the evidence for such relationships is not strong, the public will continue to drink both tea and coffee, and will continue to ask nutritionists to make recommendations. It is therefore argued that advice should be given on the best available data, as waiting for complete data to become available could have severe consequences for public health.", "title": "Tea or coffee?

Studies with human volunteers showed inhibiting effects of intake of ascorbic acid and green tea consumption on nitrosation using the N-nitrosoproline test. The aim of the present study was to evaluate the effects of ascorbic acid and green tea on urinary excretion of carcinogenic N-nitrosodimethylamine (NDMA) and N-nitrosopiperidine (NPIP) in humans. Twenty-five healthy female volunteers consumed a fish meal rich in amines as nitrosatable precursors in combination with intake of nitrate-containing drinking water at the Acceptable Daily Intake level during 7 consecutive days. During 1 week before and after nitrate intake a diet low in nitrate was consumed. Using the same protocol, the effect of two different doses of ascorbic acid (250 mg and 1 g/day) and two different doses of green tea (2 g and 4 g/day) on formation of NDMA and NPIP was studied. Mean nitrate excretion in urine significantly increased from control (76+/-24) to 167+/-25 mg/24 h. Intake of nitrate and fish resulted in a significant increase in mean urinary excretion of NDMA compared with the control weeks: 871+/-430 and 640+/-277 ng/24 h during days 1-3 and 4-7, respectively, compared with 385+/-196 ng/24 h (p<0.0002). Excretion of NPIP in urine was not related to nitrate intake and composition of the diet. Intake of 250 mg and 1 g of ascorbic acid per day resulted in a significant decrease in urinary NDMA excretion during days 4-7 (p=0.0001), but not during days 1-3. Also, consumption of four cups of green tea per day (2 g) significantly decreased excretion of NDMA during days 4-7 (p=0.0035), but not during days 1-3. Surprisingly, consumption of eight cups of green tea per day (4 g) significantly increased NDMA excretion during days 4-7 (p=0.0001), again not during days 1-3. This increase is probably a result of catalytic effects of tea polyphenols on nitrosation, or of another, yet unknown, mechanism.

Therefore, this pilot study aimed to investigate the effects of marjoram tea on the hormonal profile of women with polycystic ovary syndrome (PCOS) in a randomised, double-blind, placebo-controlled trial. METHODS: Twenty-five patients were assigned to receive marjoram tea or a placebo tea twice daily for 1 month (intervention group: n = 14; placebo group: n = 11). The hormonal and metabolic parameters measured at baseline, as well as after the intervention, were: follicle-stimulating hormone, luteinising hormone, progesterone, oestradiol, total testosterone, dehydroepiandrosterone-sulphate (DHEA-S), fasting insulin and glucose, homeostasis model assessment for insulin resistance (HOMA-IR) and glucose to insulin ratio. RESULTS: Marjoram tea significantly reduced DHEA-S and fasting insulin levels (P < 0.05) by a mean (SD) of 1.4 (0.5) μmol L-1 and 1.9 (0.8) μU mL-1 , respectively. In comparison to the placebo group, the change was only significant for DHEA-S (P = 0.05) but not for insulin (P = 0.08).

MATERIALS AND METHODS: A human model with nine subjects with no history of renal stones (non-renal stone, NS) and nine with a history of renal stones (RS) was used in this study. A cup of tea made from 1.5 g of dry Roselle calyces was provided to subjects twice daily (morning and evening) for 15 days. A clotted blood and two consecutive 24-h urine samples were collected from each subject three times: (1) at baseline (control); (2) on days 14 and 15 during the tea drinking period; and (3) 15 days after the tea drinking was stopped (washout). Serum and 24-h urinary samples were analyzed for uric acid and other chemical compositions related to urinary stone risk factors. RESULTS: All analyzed serum parameters were within normal ranges and similar; between the two groups of subjects and among the three periods. Vis-à-vis the urinary parameters, most of the baseline values for both groups were similar. After taking the tea, the trend was an increase in oxalate and citrate in both groups and uric acid excretion and clearance in the NS group. In the RS group, both uric acid excretion and clearance were significantly increased (p<0.01). When the fractional excretion of uric acid (FEUa) was calculated, the values were clearly increased in both the NS and SF groups after the intake of tea and returned to baseline values in the washout period.

It is used both as a source of caffeine, in lieu or in parallel with tea and coffee, but also as a therapeutic agent for its alleged pharmacological properties. Although with some exceptions, research on biomedical properties of this herb has had a late start and strongly lags behind the impressive amount of literature on green tea and coffee. However, in the past 15 years, there was a several-fold increase in the literature studying Ilex paraguariensis properties showing effects such as antioxidant properties in chemical models and ex vivo lipoprotein studies, vaso-dilating and lipid reduction properties, antimutagenic effects, controversial association with oropharyngeal cancer, anti-glycation effects and weight reduction properties. Lately, promising results from human intervention studies have surfaced and the literature offers several developments on this area. The aim of this review is to provide a concise summary of the research published in the past three years, with an emphasis on translational studies, inflammation and lipid metabolism. Ilex paraguariensis reduces LDL-cholesterol levels in humans with Ilex paraguariensis dyslipoproteinemia and the effect is synergic with that of statins. Plasma antioxidant capacity as well as expression of antioxidant enzymes is positively modulated by intervention with Ilex paraguariensis in human cohorts. A review on the evidence implicating Ilex paraguariensis heavy consumption with some neoplasias show data that are inconclusive but indicate that contamination with alkylating agents during the drying process of the leaves should be avoided. On the other hand, several new studies confirm the antimutagenic effects of Ilex paraguariensis in different models, from DNA double breaks in cell culture models to mice studies. Novel interesting work has emerged showing significant effect on weight reduction both in mice and in rat models. Some mechanisms involved are inhibition of pancreatic lipase, activation of AMPK and uncoupling of electron transport. Intervention studies in animals have provided strong evidence of anti-inflammatory effects of Ilex paraguariensis, notably protecting cigarette-induced lung inflammation acting on macrophage migration and inactivating matrix-metalloproteinase.

Whilst the potential benefits of green tea have been reported in a wide range of health areas, it is only in the area of the metabolic syndrome that the number of RCTs is approaching sufficient to judge such efficacy. Isoflavone supplements are widely used, and RCTs indicate that they affect bone resorption at lower doses in postmenopausal women undergoing estrogen-related bone loss, but this is only translated to attenuation of bone loss at higher doses of isoflavones. A systematic review on RCTs concluded that the effects of isoflavones on hot flashes in postmenopausal women were highly variable and no conclusions could be drawn. Despite the popularity of aloe vera as a PFS, the evaluation of its efficacy as a coadjuvant therapy for certain metabolic or digestive pathologies remains scarce; it constitutes a typical example of a naturally occurring ingredient whose efficacy in topical applications presupposes its efficacy in systemic applications. Nevertheless, its possible toxic effects on oral consumption call for caution in its utility as a PFS. Since 2007, efficacy evaluation of PFS in Europe has been covered by European Union Nutrition and Health Claims legislation.

METHODS: First- and sixth-graders (n = 77) participated in a between-subjects experimental design. All participants were offered the same gram weight of cookies during an afternoon tea at their school. For half of the participants, food was cut in 2 to make the small item size. Food intake (number of cookies, gram weight, and energy intake) was examined using ANOVA. RESULTS: Decreasing the item size of food led to a decrease of 25% in gram weight intake, corresponding to 68 kcal. Appetitive ratings and subject and food characteristics had no moderating effect. CONCLUSIONS AND IMPLICATIONS: Reducing the item size of food could prove a useful dietary prevention strategy based on decreased consumption, aimed at countering obesity-promoting eating behaviors favored by the easy availability of large food portions.

However, whether pharmacist participation in the ICU at the time of drug prescribing reduces adverse events has not been studied. OBJECTIVE To measure the effect of pharmacist participation on medical rounds in the ICU on the rate of preventable adverse drug events (ADEs) caused by ordering errors. DESIGN Before-after comparison between phase 1 (baseline) and phase 2 (after intervention implemented) and phase 2 comparison with a control unit that did not receive the intervention. SETTING A medical ICU (study unit) and a coronary care unit (control unit) in a large urban teaching hospital. PATIENTS Seventy-five patients randomly selected from each of 3 groups: all admissions to the study unit from February 1, 1993, through July 31, 1993 (baseline) and all admissions to the study unit (postintervention) and control unit from October 1, 1994, through July 7, 1995. In addition, 50 patients were selected at random from the control unit during the baseline period. INTERVENTION A senior pharmacist made rounds with the ICU team and remained in the ICU for consultation in the morning, and was available on call throughout the day. MAIN OUTCOME MEASURES Preventable ADEs due to ordering (prescribing) errors and the number, type, and acceptance of interventions made by the pharmacist. Preventable ADEs were identified by review of medical records of the randomly selected patients during both preintervention and postintervention phases. Pharmacists recorded all recommendations, which were then analyzed by type and acceptance. RESULTS The rate of preventable ordering ADEs decreased by 66% from 10.4 per 1000 patient-days (95% confidence interval [CI], 7-14) before the intervention to 3.5 (95% CI, 1-5; P<.001) after the intervention. In the control unit, the rate was essentially unchanged during the same time periods: 10.9 (95% CI, 6-16) and 12.4 (95% CI, 8-17) per 1000 patient-days. The pharmacist made 366 recommendations related to drug ordering, of which 362 (99%) were accepted by physicians. CONCLUSIONS The presence of a pharmacist on rounds as a full member of the patient care team in a medical ICU was associated with a substantially lower rate of ADEs caused by prescribing errors. Nearly all the changes were readily accepted by physicians.", "title": "Pharmacist participation on physician rounds and adverse drug events in the intensive care unit." } ]

Between January and June 1998, two pharmacists observed consecutive drug administration rounds by nurses on two wards in a U.K. hospital and recorded all MAEs identified.

MAE records were audited to determine the percentage of omitted doses for which a corresponding reason was documented for the observation periods and for nonobservation periods. Error rates for each drug administration round were analyzed according to whether they were for the nurse's first, second, third (and so on) observed round. Error rates were calculated before and after the first intervention with nurses for whom an intervention was made. Observer reliability was calculated by comparing the rates of errors identified by the two observers. There was no difference between the observation and nonobservation periods in the percentage of omitted doses for which a reason was documented, and there was no change in the error rate with repeated observations. There was no difference in error rates before and after the first intervention for each nurse. There was also no difference in error detection between the two observers and no change with increasing duration of observation. Observation of nurses during drug administration at a U.K. hospital did not significantly affect the MAE rate; nor did tactful interventions by the observers. Observer reliability was high.

DESIGN Incremental cost effectiveness analysis of a randomised controlled trial. SETTING Medical wards in 14 hospitals in the United Kingdom. PARTICIPANTS The trial comprised 236 patients admitted to hospital with an acute exacerbation of chronic obstructive pulmonary disease and mild to moderate acidosis (pH 7.25-7.35) secondary to respiratory failure. The economic analysis compared the costs of treatment that these patients received after randomisation. MAIN OUTCOME MEASURE Incremental cost per in-hospital death. RESULTS 24/118 died in the group receiving standard treatment and 12/118 in the group receiving non-invasive ventilation (P=0.05). Allocation to the group receiving non-invasive ventilation was associated with a reduction in costs of 49362 pounds sterling (78741 dollars; 73109 euros), mainly through reduced use of intensive care units. The incremental cost effectiveness ratio was -645 pounds sterling per death avoided (95% confidence interval -2310 pounds sterling to 386 pounds sterling), indicating a dominant (more effective and less costly) strategy. Modelling of these data indicates that a typical UK hospital providing a non-invasive ventilation service will avoid six deaths and three to nine admissions to intensive care units per year, with an associated cost reduction of 12000-53000 pounds sterling per year.

Units included two medical and three surgical intensive care units and four medical and two surgical general care units. MAIN OUTCOME MEASURES Adverse drug events and potential ADEs. METHODS Incidents were detected by stimulated self-report by nurses and pharmacists and by daily review of all charts by nurse investigators. Incidents were subsequently classified by two independent reviewers as to whether they represented ADEs or potential ADEs and as to severity and preventability. RESULTS Over 6 months, 247 ADEs and 194 potential ADEs were identified. Extrapolated event rates were 6.5 ADEs and 5.5 potential ADEs per 100 nonobstetrical admissions, for mean numbers per hospital per year of approximately 1900 ADEs and 1600 potential ADEs. Of all ADEs, 1% were fatal (none preventable), 12% life-threatening, 30% serious, and 57% significant. Twenty-eight percent were judged preventable. Of the life-threatening and serious ADEs, 42% were preventable, compared with 18% of significant ADEs. Errors resulting in preventable ADEs occurred most often at the stages of ordering (56%) and administration (34%); transcription (6%) and dispensing errors (4%) were less common. Errors were much more likely to be intercepted if the error occurred earlier in the process: 48% at the ordering stage vs 0% at the administration stage. CONCLUSION Adverse drug events were common and often preventable; serious ADEs were more likely to be preventable.

PATIENTS 157 Patients (mean age 66.6 (SD 8.2) years), 113 with patent grafts and 44 with occluded grafts one year after bypass. MAIN OUTCOME MEASURE Cumulative percentage patency at one year. RESULTS Markers for smoking (blood carboxyhaemoglobin concentration (p less than 0.05) and plasma thiocyanate concentration (p less than 0.01) and plasma concentrations of fibrinogen (p less than 0.001) and apolipoproteins AI (p less than 0.04) and (a) (p less than 0.05) were significantly higher in patients with occluded grafts. Serum cholesterol concentrations were significantly higher in patients with grafts that remained patent one year after bypass (p less than 0.005). Analysis of the smoking markers indicated that a quarter of patients (40) were untruthful in their claims to have stopped smoking. Based on smoking markers, patency of grafts in smokers was significantly lower at one year by life table analysis than in non-smokers (63% v 84%, p less than 0.02). Patency was significantly higher by life table analysis in patients with a plasma fibrinogen concentration below the median than in those with a concentration above (90% v 57%, p less than 0.0002). Surprisingly, increased plasma low density lipoprotein cholesterol concentration was significantly associated with improved patency at one year (85%) at values above the median compared with patency (only 68%) at values in the lower half of the range (p less than 0.02). CONCLUSIONS Plasma fibrinogen concentration was the most important variable predicting graft occlusion, followed by smoking markers.

Considerable advances have since been made into the pathobiology (changes in organ function, morphology, cell biology, biochemistry, immunology, and circulation), management, and epidemiology of sepsis, suggesting the need for reexamination. OBJECTIVE To evaluate and, as needed, update definitions for sepsis and septic shock. PROCESS A task force (n = 19) with expertise in sepsis pathobiology, clinical trials, and epidemiology was convened by the Society of Critical Care Medicine and the European Society of Intensive Care Medicine. Definitions and clinical criteria were generated through meetings, Delphi processes, analysis of electronic health record databases, and voting, followed by circulation to international professional societies, requesting peer review and endorsement (by 31 societies listed in the Acknowledgment). KEY FINDINGS FROM EVIDENCE SYNTHESIS Limitations of previous definitions included an excessive focus on inflammation, the misleading model that sepsis follows a continuum through severe sepsis to shock, and inadequate specificity and sensitivity of the systemic inflammatory response syndrome (SIRS) criteria. Multiple definitions and terminologies are currently in use for sepsis, septic shock, and organ dysfunction, leading to discrepancies in reported incidence and observed mortality. The task force concluded the term severe sepsis was redundant. RECOMMENDATIONS Sepsis should be defined as life-threatening organ dysfunction caused by a dysregulated host response to infection. For clinical operationalization, organ dysfunction can be represented by an increase in the Sequential [Sepsis-related] Organ Failure Assessment (SOFA) score of 2 points or more, which is associated with an in-hospital mortality greater than 10%. Septic shock should be defined as a subset of sepsis in which particularly profound circulatory, cellular, and metabolic abnormalities are associated with a greater risk of mortality than with sepsis alone. Patients with septic shock can be clinically identified by a vasopressor requirement to maintain a mean arterial pressure of 65 mm Hg or greater and serum lactate level greater than 2 mmol/L (>18 mg/dL) in the absence of hypovolemia. This combination is associated with hospital mortality rates greater than 40%. In out-of-hospital, emergency department, or general hospital ward settings, adult patients with suspected infection can be rapidly identified as being more likely to have poor outcomes typical of sepsis if they have at least 2 of the following clinical criteria that together constitute a new bedside clinical score termed quickSOFA (qSOFA): respiratory rate of 22/min or greater, altered mentation, or systolic blood pressure of 100 mm Hg or less. CONCLUSIONS AND RELEVANCE These updated definitions and clinical criteria should replace previous definitions, offer greater consistency for epidemiologic studies and clinical trials, and facilitate earlier recognition and more timely management of patients with sepsis or at risk of developing sepsis.", "title": "The Third International Consensus Definitions for Sepsis and Septic Shock (Sepsis-3)." }, { "docid": "24077493", "text": "BACKGROUND With increasing restrictions placed on physician-industry interactions, industry marketing may target other health professionals. Recent health policy developments confer even greater importance on the decision making of non-physician clinicians. The purpose of this systematic review is to examine the types and implications of non-physician clinician-industry interactions in clinical practice. METHODS AND FINDINGS We searched MEDLINE and Web of Science from January 1, 1946, through June 24, 2013, according to PRISMA guidelines. Non-physician clinicians eligible for inclusion were: Registered Nurses, nurse prescribers, Physician Assistants, pharmacists, dieticians, and physical or occupational therapists; trainee samples were excluded. Fifteen studies met inclusion criteria. Data were synthesized qualitatively into eight outcome domains: nature and frequency of industry interactions; attitudes toward industry; perceived ethical acceptability of interactions; perceived marketing influence; perceived reliability of industry information; preparation for industry interactions; reactions to industry relations policy; and management of industry interactions. Non-physician clinicians reported interacting with the pharmaceutical and infant formula industries. Clinicians across disciplines met with pharmaceutical representatives regularly and relied on them for practice information. Clinicians frequently received industry \"information,\" attended sponsored \"education,\" and acted as distributors for similar materials targeted at patients. Clinicians generally regarded this as an ethical use of industry resources, and felt they could detect \"promotion\" while benefiting from industry \"information. \" Free samples were among the most approved and common ways that clinicians interacted with industry. Included studies were observational and of varying methodological rigor; thus, these findings may not be generalizable. This review is, however, the first to our knowledge to provide a descriptive analysis of this literature. CONCLUSIONS Non-physician clinicians' generally positive attitudes toward industry interactions, despite their recognition of issues related to bias, suggest that industry interactions are normalized in clinical practice across non-physician disciplines. Industry relations policy should address all disciplines and be implemented consistently in order to mitigate conflicts of interest and address such interactions' potential to affect patient care.

Nine of the studies examined the role of pharmacists in providing treatment recommendations and patient education, five featured pharmacists as providers (with prescriptive authority), and the remaining two described the impact pharmacists have in delivering education to the psychiatric staff. Six of the 16 studies were prospective, but only three of these incorporated a randomization procedure for patients or facilities. Collectively, the results of the 16 studies were positive, demonstrating improvements in outcomes, prescribing practices, patient satisfaction, and resource use.

Some medications have been proven to help people to quit, with three licensed for this purpose in Europe and the USA: nicotine replacement therapy (NRT), bupropion, and varenicline. Cytisine (a treatment pharmacologically similar to varenicline) is also licensed for use in Russia and some of the former socialist economy countries. Other therapies, including nortriptyline, have also been tested for effectiveness. OBJECTIVES How do NRT, bupropion and varenicline compare with placebo and with each other in achieving long-term abstinence (six months or longer)? How do the remaining treatments compare with placebo in achieving long-term abstinence? How do the risks of adverse and serious adverse events (SAEs) compare between the treatments, and are there instances where the harms may outweigh the benefits? METHODS The overview is restricted to Cochrane reviews, all of which include randomised trials. Participants are usually adult smokers, but we exclude reviews of smoking cessation for pregnant women and in particular disease groups or specific settings. We cover nicotine replacement therapy (NRT), antidepressants (bupropion and nortriptyline), nicotine receptor partial agonists (varenicline and cytisine), anxiolytics, selective type 1 cannabinoid receptor antagonists (rimonabant), clonidine, lobeline, dianicline, mecamylamine, Nicobrevin, opioid antagonists, nicotine vaccines, and silver acetate. Our outcome for benefit is continuous or prolonged abstinence at least six months from the start of treatment. Our outcome for harms is the incidence of serious adverse events associated with each of the treatments. We searched the Cochrane Database of Systematic Reviews (CDSR) in The Cochrane Library, for any reviews with 'smoking' in the title, abstract or keyword fields. The last search was conducted in November 2012. We assessed methodological quality using a revised version of the AMSTAR scale. For NRT, bupropion and varenicline we conducted network meta-analyses, comparing each with the others and with placebo for benefit, and varenicline and bupropion for risks of serious adverse events. MAIN RESULTS We identified 12 treatment-specific reviews. The analyses covered 267 studies, involving 101,804 participants. Both NRT and bupropion were superior to placebo (odds ratios (OR) 1.84; 95% credible interval (CredI) 1.71 to 1.99, and 1.82; 95% CredI 1.60 to 2.06 respectively). Varenicline increased the odds of quitting compared with placebo (OR 2.88; 95% CredI 2.40 to 3.47). Head-to-head comparisons between bupropion and NRT showed equal efficacy (OR 0.99; 95% CredI 0.86 to 1.13). Varenicline was superior to single forms of NRT (OR 1.57; 95% CredI 1.29 to 1.91), and to bupropion (OR 1.59; 95% CredI 1.29 to 1.96). Varenicline was more effective than nicotine patch (OR 1.51; 95% CredI 1.22 to 1.87), than nicotine gum (OR 1.72; 95% CredI 1.38 to 2.13), and than 'other' NRT (inhaler, spray, tablets, lozenges; OR 1.42; 95% CredI 1.12 to 1.79), but was not more effective than combination NRT (OR 1.06; 95% CredI 0.75 to 1.48). Combination NRT also outperformed single formulations. The four categories of NRT performed similarly against each other, apart from 'other' NRT, which was marginally more effective than NRT gum (OR 1.21; 95% CredI 1.01 to 1.46). Cytisine (a nicotine receptor partial agonist) returned positive findings (risk ratio (RR) 3.98; 95% CI 2.01 to 7.87), without significant adverse events or SAEs. Across the 82 included and excluded bupropion trials, our estimate of six seizures in the bupropion arms versus none in the placebo arms was lower than the expected rate (1:1000), at about 1:1500. SAE meta-analysis of the bupropion studies demonstrated no excess of neuropsychiatric (RR 0.88; 95% CI 0.31 to 2.50) or cardiovascular events (RR 0.77; 95% CI 0.37 to 1.59). SAE meta-analysis of 14 varenicline trials found no difference between the varenicline and placebo arms (RR 1.06; 95% CI 0.72 to 1.55), and subgroup analyses detected no significant excess of neuropsychiatric events (RR 0.53; 95% CI 0.17 to 1.67), or of cardiac events (RR 1.26; 95% CI 0.62 to 2.56). Nortriptyline increased the chances of quitting (RR 2.03; 95% CI 1.48 to 2.78). Neither nortriptyline nor bupropion were shown to enhance the effect of NRT compared with NRT alone. Clonidine increased the chances of quitting (RR 1.63; 95% CI 1.22 to 2.18), but this was offset by a dose-dependent rise in adverse events. Mecamylamine in combination with NRT may increase the chances of quitting, but the current evidence is inconclusive. Other treatments failed to demonstrate a benefit compared with placebo. Nicotine vaccines are not yet licensed for use as an aid to smoking cessation or relapse prevention. Nicobrevin's UK license is now revoked, and the manufacturers of rimonabant, taranabant and dianicline are no longer supporting the development or testing of these treatments. AUTHORS' CONCLUSIONS NRT, bupropion, varenicline and cytisine have been shown to improve the chances of quitting. Combination NRT and varenicline are equally effective as quitting aids. Nortriptyline also improves the chances of quitting. On current evidence, none of the treatments appear to have an incidence of adverse events that would mitigate their use. Further research is warranted into the safety of varenicline and into cytisine's potential as an effective and affordable treatment, but not into the efficacy and safety of NRT.", "title": "Pharmacological interventions for smoking cessation: an overview and network meta-analysis." }, { "docid": "38799797", "text": "Interventions by the pharmacists have always been considered as a valuable input by the health care community in the patient care process by reducing the medication errors, rationalizing the therapy and reducing the cost of therapy.

METHODS We did a two-by-two factorial, cluster-randomised trial in Dadu, a rural area of Sindh province, Pakistan. Clusters were defined as the population covered by a functional traditional birth attendant (TBA), and were randomly allocated to one of four groups (groups A to D) with a computer-generated random number sequence. Implementation and data collection teams were masked to allocation. Liveborn infants delivered by participating TBAs who received birth kits were eligible for enrolment in the study. One intervention comprised birth kits containing 4% CHX solution for application to the cord at birth by TBAs and once daily by family members for up to 14 days along with soap and educational messages promoting handwashing. One intervention was CHX solution only and another was handwashing only. Standard dry cord care was promoted in the control group.

METHODS We surveyed internists and OB/GYNs who attended Grand Rounds presentations developed for the New York State Women and Heart Disease Physician Education Initiative. This program was designed to improve screening and management of coronary risk factors in women. Attendees were asked to complete a 7-minute questionnaire. RESULTS The mean age of the 529 respondents was 40.3 years (standard deviation = 12.3), 75.1% were internists (n=378), and 42.7% (n=226) were women. Physicians correctly responded to 71.5% of the 13 questions assessing knowledge of coronary risk prevention (range, 4-13). Almost one third of internists and half of the OB/GYNs did not know that tobacco use was the leading cause of myocardial infarction in young women. For patients who smoked tobacco, only two thirds of internists and 55.4% of OB/GYNs reported suggesting a quit date (p=.007).

Although female gender carries a higher risk of developing relapsing remitting MS, being female and at child-bearing age also appears to provide some protection against cognitive decline and against progressive onset MS, an adverse predictive factor when considering long-term disability in MS. The risk of MS in women has been associated with an earlier age at menarche. In most studies, parity did not impact MS risk. However, the recently published association of higher parity and offspring number with a reduced risk of a first demyelinating event suggests a potential suppressive effect. Pregnancy in MS patients has been associated with a reduced relapse rate and a reduction of neurological symptoms, especially in the third trimester. Despite the increased relapse risk in the postpartum period, there is no indication of an adverse effect of childbirth on the long-term course of MS. Fertility treatment in MS has been associated with an increased relapse risk in the following 3-month period, especially when the procedure did not result in pregnancy and gonadotrophin-releasing hormone agonists were used. Altogether, there is substantial evidence to support a regulatory role of sex steroid hormones in MS.

The aim of this study was to assess whether HPV DNA testing in the first screen decreases detection of cervical intraepithelial neoplasia (CIN) grade 3 or worse, CIN grade 2 or worse, and cervical cancer in the second screening. METHODS In this randomised trial, women aged 29-56 years participating in the cervical screening programme in the Netherlands were randomly assigned to receive HPV DNA (GP5+/6+-PCR method) and cytology co-testing or cytology testing alone, from January, 1999, to September, 2002. Randomisation (in a 1:1 ratio) was done with computer-generated random numbers after the cervical specimen had been taken. At the second screening 5 years later, HPV DNA and cytology co-testing was done in both groups; researchers were masked to the patient's assignment. The primary endpoint was the number of CIN grade 3 or worse detected. Analysis was done by intention to screen. The trial is now finished and is registered, number ISRCTN20781131. FINDINGS 22,420 women were randomly assigned to the intervention group and 22 518 to the control group; 19 999 in the intervention group and 20,106 in the control group were eligible for analysis at the first screen. At the second screen, 19 579 women in the intervention group and 19,731 in the control group were eligible, of whom 16,750 and 16,743, respectively, attended the second screen. In the second round, CIN grade 3 or worse was less common in the intervention group than in the control group (88 of 19 579 in the intervention group vs 122 of 19,731 in the control group; relative risk 0·73, 95% CI 0·55-0·96; p=0·023).

RESEARCH DESIGN AND METHODS A total of 657 patients (age: 12.1 +/- 4.4 years, mean +/- SD) were included in the study, yielding 1,449 patient-years of data. A prospective assessment of severe hypoglycemia (an event resulting in a seizure or coma) and moderate hypoglycemia (an event requiring assistance of another, excluding severe episodes) was made over a 3-year period. Patients and caregivers detailed episodes of significant hypoglycemia (moderate and severe events) and these were recorded at each 3-month clinic visit along with HbA1c. Data were analyzed using generalized estimating equation models fitted with the exchange correlation structure. RESULTS The overall incidence of severe events was 4.8/100 patient-years and of moderate events was 13.1/100 patient-years. Over 3 years, severe events occurred in 8.5% of children and moderate events occurred in 26.9%. Significant hypoglycemia was rare in the first 12 months after diagnosis. Rates of hypoglycemia were increased in children < 6 years of age versus > 6 years of age (40.9 vs. 16.6/100 patient-years, age < or = 6 years vs. age > 6 years, P < 0.001). Rates of hypoglycemia doubled when HbA1c fell below 8%, and children with HbA1c < 7% had a threefold increase in both moderate and severe hypoglycemia (e.g., severe episodes 14.9 vs. 4.1/100 patient-years, HbA1c < or = 7% vs. HbA1c > 7%, P < 0.001). Most severe events were seizures, and 75% of them occurred at night. The majority of events were related to missed meals or increased activity. However, in 38% no predisposing factor was evident.

Lesion-related risk factors for such events are poorly understood. METHODS In a prospective study, 697 patients with acute coronary syndromes underwent three-vessel coronary angiography and gray-scale and radiofrequency intravascular ultrasonographic imaging after percutaneous coronary intervention. Subsequent major adverse cardiovascular events (death from cardiac causes, cardiac arrest, myocardial infarction, or rehospitalization due to unstable or progressive angina) were adjudicated to be related to either originally treated (culprit) lesions or untreated (nonculprit) lesions. The median follow-up period was 3.4 years. RESULTS The 3-year cumulative rate of major adverse cardiovascular events was 20.4%. Events were adjudicated to be related to culprit lesions in 12.9% of patients and to nonculprit lesions in 11.6%. Most nonculprit lesions responsible for follow-up events were angiographically mild at baseline (mean [±SD] diameter stenosis, 32.3±20.6%). However, on multivariate analysis, nonculprit lesions associated with recurrent events were more likely than those not associated with recurrent events to be characterized by a plaque burden of 70% or greater (hazard ratio, 5.03; 95% confidence interval [CI], 2.51 to 10.11; P<0.001) or a minimal luminal area of 4.0 mm(2) or less (hazard ratio, 3.21; 95% CI, 1.61 to 6.42; P=0.001) or to be classified on the basis of radiofrequency intravascular ultrasonography as thin-cap fibroatheromas (hazard ratio, 3.35; 95% CI, 1.77 to 6.36; P<0.001).

The IOM Report [1] points out that some systems are more prone to accidents than others. When a system fails there are often multiple faults. In healthcare,human errors are the greatest contributors to accidents,however when human error is to blame it often depends upon failures within the system. These failures exists in the system before the error occurs, the same as with latent errors which are difficult to identify since they may be hidden in computers or within the various managerial layers. Most of the errors can be prevented by designing systems that make it hard for people to do the wrong thing and easy for people to do the right thing. In healthcare, this means designing processes that are able to ensure that patients are safe from accidental injury. As healthcare and the system that delivers it become more complex, the opportunities for errors abound. The IOM report “To Err is Human” proposes an approach for reducing medical errors and improving patient safety. The environment within which this occurs has a critical influence on quality.

The second dimension consists of forces in the external environment that can drive quality improvement in the delivery system. Although the risk of dying as a result of a medical error, far surpasses the risk of dying in an airline accident, public attention has been more focused on improving safety in the airline industry than in healthcare systems. Because of the absence of standardized nomenclature, it is important to define what an error is and what is an adverse event, the IOM Report defines them in the following way: “An error is the failure of a planned action to be completed as intended or the use of a wrong plan to achieve an aim. ” An adverse event is an injury caused by medical management rather than the underlying condition of the patient.

We assessed the efficacy of cervical-cancer screening policies that are based on HPV testing. METHODS Between March, 2004, and December, 2004, in two separate recruitment phases, women aged 25-60 years were randomly assigned to conventional cytology or to HPV testing in combination with liquid-based cytology (first phase) or alone (second phase). Randomisation was done by computer in two screening centres and by sequential opening of numbered sealed envelopes in the remaining seven centres. During phase one, women who were HPV-positive and aged 35-60 years were referred to colposcopy, whereas women aged 25-34 years were referred to colposcopy only if cytology was also abnormal or HPV testing was persistently positive. During phase two, women in the HPV group were referred for colposcopy if the HPV test was positive. Two rounds of screening occurred in each phase, and all women had cytology testing only at the second round. The primary endpoint was the detection of grade 2 and 3 CIN, and of invasive cervical cancers during the first and second screening rounds. Analysis was done by intention to screen. This trial is registered, number ISRCTN81678807. FINDINGS In total for both phases, 47,001 women were randomly assigned to the cytology group and 47,369 to HPV testing. 33,851 women from the cytology group and 32,998 from the HPV-testing group had a second round of screening. We also retrieved the histological diagnoses from screening done elsewhere. The detection of invasive cervical cancers was similar for the two groups in the first round of screening (nine in the cytology group vs seven in the HPV group, p=0.62); no cases were detected in the HPV group during round two, compared with nine in the cytology group (p=0.004). Overall, in the two rounds of screening, 18 invasive cancers were detected in the cytology group versus seven in the HPV group (p=0.028). Among women aged 35-60 years, at round one the relative detection (HPV vs cytology) was 2.00 (95% CI 1.44-2.77) for CIN2, 2.08 (1.47-2.95) for CIN3, and 2.03 (1.60-2.57) for CIN2 and 3 together. At round two the relative detection was 0.54 (0.23-1.28) for CIN2, 0.48 (0.21-1.11) for CIN3, and 0.51 (0.28-0.93) for CIN2 and 3 together. Among women aged 25-34 years, there was significant heterogeneity between phases in the relative detection of CIN3. At round one the relative detection was 0.93 (0.52-1.64) in phase one and 3.91 (2.02-7.57) in phase two. At round two the relative detection was 1.34 (0.46-3.84) in phase one and 0.20 (0.04-0.93) in phase two. Pooling both phases, the detection ratio of CIN2 for women aged 25-34 years was 4.09 (2.24-7.48) at round one and 0.64 (0.23-1.27) at round two. INTERPRETATION HPV-based screening is more effective than cytology in preventing invasive cervical cancer, by detecting persistent high-grade lesions earlier and providing a longer low-risk period.

BACKGROUND In recent years, accumulating evidence has indicated that corin plays a critical role in regulating blood pressure and cardiac function. METHODS We enrolled 1,148 consecutive CHF patients in a prospective cohort study and explored the association between plasma corin levels and clinical prognosis using multivariate Cox regression analysis. RESULTS Patients with low corin levels (<458 pg/ml) were more likely to be women and to be hypertensive. Low corin was found to be associated with an increase in New York Heart Association (NYHA) functional class and N-terminal pro-B-type natriuretic peptide (NT-proBNP) levels, and a decrease in left ventricular ejection fraction (LVEF) and the estimated glomerular filtration rate (eGFR). Multivariate Cox regression analysis suggested that log corin was an independent predictor of major adverse cardiac event(s) (MACE) (hazard ratio: 0.62; 95% confidence interval: 0.39 to 0.95), together with age, diabetes, NYHA functional class, LVEF, eGFR, and log NT-proBNP. In addition, log corin was also a significant predictor for cardiovascular death (p = 0.041) and heart failure rehospitalization (p = 0.015) after adjustment for clinical variables and established biomarkers of adverse prognosis. The Kaplan-Meier survival curves showed that low corin was a significant predictor of MACE in patients with NT-proBNP levels above and below the median.

However, the timing for the initiation of ART during tuberculosis treatment remains unresolved. METHODS We conducted a three-group, open-label, randomized, controlled trial in South Africa involving 642 ambulatory patients, all with tuberculosis (confirmed by a positive sputum smear for acid-fast bacilli), human immunodeficiency virus infection, and a CD4+ T-cell count of less than 500 per cubic millimeter. Findings in the earlier-ART group (ART initiated within 4 weeks after the start of tuberculosis treatment, 214 patients) and later-ART group (ART initiated during the first 4 weeks of the continuation phase of tuberculosis treatment, 215 patients) are presented here. RESULTS At baseline, the median CD4+ T-cell count was 150 per cubic millimeter, and the median viral load was 161,000 copies per milliliter, with no significant differences between the two groups. The incidence rate of the acquired immunodeficiency syndrome (AIDS) or death was 6.9 cases per 100 person-years in the earlier-ART group (18 cases) as compared with 7.8 per 100 person-years in the later-ART group (19 cases) (incidence-rate ratio, 0.89; 95% confidence interval [CI], 0.44 to 1.79; P=0.73). However, among patients with CD4+ T-cell counts of less than 50 per cubic millimeter, the incidence rates of AIDS or death were 8.5 and 26.3 cases per 100 person-years, respectively (incidence-rate ratio, 0.32; 95% CI, 0.07 to 1.13; P=0.06). The incidence rates of the immune reconstitution inflammatory syndrome (IRIS) were 20.1 and 7.7 cases per 100 person-years, respectively (incidence-rate ratio, 2.62; 95% CI, 1.48 to 4.82; P<0.001). Adverse events requiring a switching of antiretroviral drugs occurred in 10 patients in the earlier-ART group and 1 patient in the later-ART group (P=0.006). CONCLUSIONS Early initiation of ART in patients with CD4+ T-cell counts of less than 50 per cubic millimeter increased AIDS-free survival. Deferral of the initiation of ART to the first 4 weeks of the continuation phase of tuberculosis therapy in those with higher CD4+ T-cell counts reduced the risks of IRIS and other adverse events related to ART without increasing the risk of AIDS or death.

Should I “hedge” my IRA portfolio with a life cycle / target date mutual fund?

Next, on the question of the use of a life cycle / target date fund as a \"\"hedge\"\": Life cycle funds were introduced for hands-off, one-stop-shopping investors who don't like a hassle or don't understand. Such funds are gaining in popularity: employers can use them as a default choice for automatic enrollment, which results in more participation in retirement savings plans than if employees had to opt-in. I think life cycle funds are a good innovation for that reason. But, the added service and convenience typically comes with higher fees. If you are going to be hands-off, make sure you're cost-conscious: Fees can devastate a portfolio's performance. In your case, it sounds like you are willing to do some work for your portfolio. If you are confident that you've chosen a good equity glide path – that is, the initial and final stock/bond allocations and the rebalancing plan to get from one to the other – then you're not going to benefit much by having a life cycle fund in your portfolio duplicating your own effort with inferior components. (I assume you are selecting great low-cost, liquid index funds for your own strategy!) Life cycle are neat, but replicating them isn't rocket science. However, I see a few cases in which life cycle funds may still be useful even if one has made a decision to be more involved in portfolio construction: Similar to your case: You have a company savings plan that you're taking advantage of because of a matching contribution. Chances are your company plan doesn't offer a wide variety of funds. Since a life cycle fund is available, it can be a good choice for that account. But make sure fees aren't out of hand. If much lower-cost equity and bond funds are available, consider them instead. Let's say you had another smaller account that you were unable to consolidate into your main account. (e.g. a Traditional IRA vs. your Roth, and you didn't necessarily want to convert it.) Even if that account had access to a wide variety of funds, it still might not be worth the added hassle or trading costs of owning and rebalancing multiple funds inside the smaller account. There, perhaps, the life cycle fund can help you out, while you use your own strategy in your main account. Finally, let's assume you had a single main account and you buy partially into the idea of a life cycle fund and you find a great one with low fees. Except: you want a bit of something else in your portfolio not provided by the life cycle fund, e.g. some more emerging markets, international, or commodity stock exposure. (Is this one reason you're doing it yourself?) In that case, where the life cycle fund doesn't quite have everything you want, you could still use it for the bulk of the portfolio (e.g. 85-95%) and then select one or two specific additional ETFs to complement it. Just make sure you factor in those additional components into the overall equity weighting and adjust your life cycle fund choice accordingly (e.g. perhaps go more conservative in the life cycle, to compensate.)

In order to give you a good answer we need to see what options your employer gives for 401k investments. The best advice would be to take a list of all options that your employer allows and talk with a financial advisor. Here are a few options that you may or may not have as an option from an employer: Definitions from wikipedia: A target-date fund – also known as a lifecycle, dynamic-risk or age-based fund – is a collective investment scheme, usually a mutual fund, designed to provide a simple investment solution through a portfolio whose asset allocation mix becomes more conservative as the target date (usually retirement) approaches. An index fund or index tracker is a collective investment scheme (usually a mutual fund or exchange-traded fund) that aims to replicate the movements of an index of a specific financial market... An exchange-traded fund (ETF) is an investment fund traded on stock exchanges, much like stocks.[1] An ETF holds assets such as stocks, commodities, or bonds, and trades close to its net asset value over the course of the trading day. Most ETFs track an index, such as a stock index or bond index. ETFs may be attractive as investments because of their low costs, tax efficiency, and stock-like features. The capital stock (or stock) of an incorporated business constitutes the equity stake of its owners. Which one can you lose everything in? You can lose everything in stocks by the company going under. In Index funds the entire market that it follows would have to collapse. The chances are slim here since the index made up of several companies. The S&P 500 is made up of 500 leading companies publicly traded in the U.S. A Pacific-Europe index such as MSCI EAFE Index is made up of 907 companies. The chances of losing everything in an ETF are also slim. The ETF that follows the S&P 500 is made up of 500 companies. An Pacific-Europe ETF such as MSCI EAFE ETF is made up of 871 companies. Target date funds are also slim to lose everything. Target date funds are made up of several companies like indexes and etfs and also mix in bonds and other investments depending on your age. What would I recommend? I would recommend the Index funds and/or ETFs that have the lowest fee that make up the following strategy for your age: Why Not Target Date Funds or Stocks? Target date funds have high fees. Later in life when you are closer to retirement you may want to add bonds to your portfolio. At that time if this is the only option to add bonds then you can change your elections. Stocks are too risky for you with your current knowledge.

Your desire to never \"\"have to recover\"\" indicates that you have not yet done quite enough reading on the subject of investing. (Or possibly that your sources have been misleading you.) A basic understanding of investing includes the knowledge that markets go up and down, and that no portfolio will always go up. Some \"\"recovery\"\" will always be necessary; having a less aggressive portfolio will never shield you completely from losing money, it just makes loss less likely. The important thing is to only invest money that you can afford to lose in the short-term (with the understanding that you'll make it back in the long term).

Your portfolio is usually a mix of the following asset classes: You can break down these asset classes further, but each one is a topic unto itself. If you are young, you want to invest in things that have a higher return, but are more volatile, because market fluctuations (like the current financial meltdown) will be long gone before you reach retirement age. This means that at a younger age, you should be investing more in stocks and foreign/developing countries. If you are older, you need to be into more conservative investments (bonds, money market, etc). If you were in your 50s-60s and still heavily invested in stock, something like the current financial crisis could have ruined your retirement plans. (A lot of baby boomers learned this the hard way.) For most of your life, you will probably be somewhere in between these two. Start aggressive, and gradually get more conservative as you get older. You will probably need to re-check your asset allocation once every 5 years or so. As for how much of each investment class, there are no hard and fast rules. The idea is to maximize return while accepting a certain amount of risk. There are two big unknowns in there: (1) how much return do you expect from the various investments, and (2) how much risk are you willing to accept. #1 is a big guess, and #2 is personal opinion. A general portfolio guideline is \"\"100 minus your age\"\". This means if you are 20, you should have 80% of your retirement portfolio in stocks. If you are 60, your retirement portfolio should be 40% stock. Over the years, the \"\"100\"\" number has varied. Some financial advisor types have suggested \"\"150\"\" or \"\"200\"\". Unfortunately, that's why a lot of baby boomers can't retire now. Above all, re-balance your portfolio regularly. At least once a year, perhaps quarterly if the market is going wild. Make sure you are still in-line with your desired asset allocation. If the stock market tanks and you are under-invested in stocks, buy more stock, selling off other funds if necessary. (I've read interviews with fund managers who say failure to rebalance in a down stock market is one of the big mistakes people make when managing a retirement portfolio.) As for specific mutual fund suggestions, I'm not going to do that, because it depends on what your 401k or IRA has available as investment options. I do suggest that your focus on selecting a \"\"passive\"\" index fund, not an actively managed fund with a high expense ratio. Personally, I like \"\"total market\"\" funds to give you the broadest allocation of small and big companies. (This makes your question about large/small cap stocks moot.) The next best choice would be an S&P 500 index fund. You should also be able to find a low-cost Bond Index Fund that will give you a healthy mix of different bond types. However, you need to look at expense ratios to make an informed decision. A better-performing fund is pointless if you lose it all to fees! Also, watch out for overlap between your fund choices. Investing in both a Total Market fund, and an S&P 500 fund undermines the idea of a diversified portfolio. An aggressive portfolio usually includes some Foreign/Developing Nation investments. There aren't many index fund options here, so you may have to go with an actively-managed fund (with a much higher expense ratio). However, this kind of investment can be worth it to take advantage of the economic growth in places like China. http://www.getrichslowly.org/blog/2009/04/27/how-to-create-your-own-target-date-mutual-fund/\"", "title": "" }, { "docid": "240975", "text": "First, you should diversify your portfolio. If your entire portfolio is in the Roth IRA, then you should eventually diversify that. However, if you have an IRA and a 401k, then it's perfectly fine for the IRA to be in a single fund. For example, I used my IRA to buy a riskier REIT that my 401k doesn't support. Second, if you only have a small amount currently invested, e.g. $5500, it may make sense to put everything in a single fund until you have enough to get past the low balance fees. It's not uncommon for funds to charge lower fees to someone who has $8000, $10,000, or $12,000 invested. Note that if you deposit $10,000 and the fund loses money, they'll usually charge you the rate for less than $10,000. So try to exceed the minimum with a decent cushion. A balanced fund may make sense as a first fund. That way they handle the diversification for you. A targeted fund is a special kind of balanced fund that changes the balance over time. Some have reported that targeted funds charge higher fees. Commissions on those higher fees may explain why your bank wants you to buy. I personally don't like the asset mixes that I've seen from targeted funds. They often change the stock/bond ratio, which is not really correct. The stock/bond ratio should stay the same. It's the securities (stocks and bonds) to monetary equivalents that should change, and that only starting five to ten years before retirement. Prior to that the only reason to put money into monetary equivalents is to provide time to pick the right securities fund. Retirees should maintain about a five year cushion in monetary equivalents so as not to be forced to sell into a bad market. Long term, I'd prefer low-load index funds. A bond fund and two or three stock funds. You might want to build your balance first though. It doesn't really make sense to have a separate fund until you have enough money to get the best fees. 70-75% stocks and 25-30% bonds (should add to 100%, e.g. 73% and 27%).

For this fund, the breakdown is: Then, look at the allocation of the underlying funds that comprise the lifecycle fund, in the same tab. Look at each of those funds and see what asset allocation they use, and that should give you a rough idea for an age-based allocation.

Doing this for several lifecycle funds should be a good start. Keep in mind, however, that these funds are rebalanced as the target date approaches, so if you're following the allocation of some particular funds, you'll have to rebalance as well. If you really want an age-based allocation that you don't have to think about, invest in a lifecycle fund directly. You'll probably pay a lower expense ratio than if you invested in a whole slew of funds directory, and it's less work for someone who isn't comfortable managing their portfolio themselves.

Is it normal to see down years? Yes, absolutely. It's a function of the directional bias of how the portfolio is invested. In the case of a 401(k) that almost always mean a positive directional bias (being long). Now, in your case I see two issues: The amount of drawdown over one year. It is atypical to have a 14% loss in a little over a year. Given the market conditions, this means that you nearly experienced the entire drawdown of the SP500 (which your portfolio is highly correlated to) and you have no protection from the downside. The use of so-called \"\"target-date funds\"\". Their very implication makes no sense. Essentially, they try to generate a particular return over the elapsed time until retirement. The issue is that the market is by all statistical accounts random with positive drift (it can be expected to move up in the long term). This positive drift is due to the fact that people should be paid to take on risk. So if you need the money 20 years from now, what's the big deal? Well, the issue is that no one, and I repeat, no one, knows when the market will experience long down moves. So you happily experience positive drift for 20 years and your money grows to a decent size. Then, right before you retire, the market shaves 20%+ of your investments. Will you recoup these damages? Most likely yes. But will that be in the timeframe you need? The market doesn't care if you need money or not. So, here is my advice if you are comfortable taking control of your money. See if you can roll your money into an IRA (some 401(k) plans will permit this) or, if you contribute less that the 401(k) contribution limit you make want to just contribute to an IRA (be mindful of the annual limits). In this case, you can set up a self-directed account. Here you will have the flexibility to diversify and take action as necessary. And by diversify, I don't mean that \"\"buy lots of different stuff\"\" garbage, I mean focus on uncorrelated assets. You can get by on a handful of ETFs (SPY, TLT, QQQ, ect.). These all have liquid options available. Once you build a base, you can lower basis by writing covered calls against these positions. This is allowed in almost all IRA accounts. In my opinion, and I see this far too often, your potential and drive to take control of your assets is far superior than the so called \"\"professionals or advisors\"\".

Ordinarily nothing stops you from participating in your 401(k), opening an IRA, qualifying for your company's pension, and paying off your debts except your ability to pay for all this stuff. Moreover, you can open an IRA anywhere (scottrade, vanguard, etrade, etc.) and freely invest in vanguard mutual funds as well as those of other companies...you aren't normally locked in to the funds of your IRA provider. Consider a traditional IRA. To me your marginal tax rate of 25% doesn't seem that great. If I were in your shoes I would be more likely to contribute to a traditional IRA instead of a Roth. This will save you taxes today and you can put the extra 25% of $5,500 toward your loans. Yes, you will be taxed on that money when you retire, but I think it's likely your rate will be lower than 25%. Moreover, when you are retired you will already own a house and have paid off all your debt, hopefully. You kind of need money now. Between your current tax rate and your need for money now, I'd say a traditional makes good sense. Buy whatever funds you want. If you want a single, cheap, whole-market fund just buy VTSAX. You will need a minimum of $10K to get in, so until then you can buy the ETF version, VTI. Personally I would contribute enough to your 401(k) to get the match and anything else to an IRA (usually they have more and better investment options). If you max that out, go back to the 401(k). Your investment mix isn't that important. Recent research into target date funds puts them in a poor light. Since there isn't a good benchmark for a target date fund, the managers tend to buy whatever they feel like and it may not be what you would prefer if you were choosing. However, the fund you mention has a pretty low expense ratio and the difference between that and your own allocation to an equity index fund or a blend of equity and bond funds is small in expectation. Plus, you can change your allocation whenever you want. You are not locked in. The investment options you mention are reasonable enough that the difference between portfolios is not critical. More important is optimizing your taxes and paying off your debt in the right order. Your interest rates matter more than term does. Paying off debt with more debt will help you if the new debt has a lower interest rate and it won't if it has a higher interest rate. Normally speaking, longer term debt has a higher interest rate. For that reason shorter term debt, if you can afford it, is generally better. Be cold and calculating with your debt. Always pay off highest interest rate debt first and never pay off cheap debt with expensive debt. If the 25 year debt option is lower than all your other interest rates and will allow you to pay off higher interest rate debt faster, it's a good idea. Otherwise it most likely is not.

Most people in their lifetime will need a mix of Roth and Regular retirement accounts. You need to determine if it is better for you to pay the tax on your contributions now or later. Which accounts?

The selection depends on what non-401K investments you have. Now here is what I considered the best advice. Decide Roth or regular, and just put the money into the most appropriate target date fund with the Roth/regular split you want. Then after the money starts flowing into your account, research the funds involved, the fees for those funds, and how you want to invest. Then move the money into the funds you want.

Odd. Usually 401(k) contributions are limited to some dollar amount in the vicinity of $15,000 or so a year.

I'd try to contribute 10-15% of my salary. I think you're reading the rules wrong. I'm almost certain. It's definitely worth checking. If you're not, you should seriously consider supplementing this saving with a Roth IRA or just an after-tax account. So. If you're with Fidelity and don't know what to do, look for a target date fund with a date near your retirement (e.g. Target Retirement 2040) and put 100% in there until you have a better idea of what going on. All Fidelity funds have pretty miserable expense ratios, even their token S&P500 index fund from another provider, so you might as let them do some leg work and pick your asset allocation for you. Alternatively, look for the Fidelity retirement planner tools on their website to suggest an asset allocation. As a (very rough) rule of thumb, as you're saving for retirement you'll want to have N% of your portfolio in bonds and the rest in stocks, where N is your age in years. Your stocks should probably be split about 70% US and 30% rest-of-world, give or take, and your US stocks should be split about 64% large-cap, 28% mid-cap and 8% small-cap (that's basically how the US stock market is split).", "title": "" }, { "docid": "549364", "text": "\"As you alluded to in your question, there is not one answer that will be true for all mutual funds. In fact, I would argue the question is not specific to mutual funds but can be applied to almost anyone who must make an investment decision: a mutual fund manager, hedge fund manager, or an individual investor. Even though money going into a company 401(k) retirement savings plan is typically automatically allocated to different funds as we have specified, this is generally not the case for other investment accounts. For example, I also have a Roth IRA in which I have some money from each paycheck direct deposited and it's up to me to decide whether to leave that money in cash or to invest it somewhere else. Every time you invest more money into a mutual fund, the fund manager has the same decision to make. There are two commonly used mutual fund figures that relate to your question: turnover rate, and cash reserves. Turnover rate measures the percent of a fund's portfolio that changes every year. For example, a turnover rate of 100% indicates that a fund replaces every asset it held at the beginning of the year with something else at the end of the year – funds with turnover rates greater than 100% average a holding period for a given asset of less than one year, and funds with turnover rates less than 100% average a holding period for a given asset of more than one year. Cash reserves simply measure the amount of money funds choose to keep as cash instead of investing in other assets. Another important distinction to make is between actively managed funds and passively managed funds. Passively managed funds are often referred to as \"\"index funds\"\" and have as their goal only to match the returns of a given index or some other benchmark. Actively managed funds on the other hand try to beat the market by exploiting so-called market inefficiencies; e.g. buying undervalued assets, selling overvalued assets, \"\"timing\"\" the market, etc. To answer your question for a specific fund, I would encourage you to look at the fund's prospectus. I take as one example of a passively managed fund the Vanguard 500 Index Fund (VFINX), a mutual fund that was created to track the S&P 500. In its prospectus, the fund states that, \"\"to track its target index as closely as possible, the Fund attempts to remain fully invested in stocks\"\". Furthermore, the prospectus states that \"\"the fund's daily cash balance may be invested in one or more Vanguard CMT Funds, which are very low-cost money market funds.\"\" Therefore, we would expect both this fund's turnover rate and cash reserves to be extremely low. When we look at its portfolio composition, we see this is true – it is currently at a 4.8% turnover rate and holds 0.0% in short term reserves. Therefore, we can assume this fund is regularly purchasing shares (similar to a dollar cost averaging strategy) instead of holding on to cash and purchasing shares together at a specific time. For actively managed funds, the picture will tend to look a little different. For example, if we look at the Magellan Fund's portfolio composition, we can see it has a turnover rate of 42%, and holds around .95% in cash/short term reserves. In this case, we can safely guess that trading activity may not be as regular as a passively managed fund, as an active manager attempts to time the market. You may find mutual funds that have much higher cash reserves – perhaps 10% or even more. Granted, it is impossible to know the exact trading strategy of a mutual fund, and for good reason – if we knew for example, that a fund purchases shares every day at 2:30PM in order to realign with the S&P 500, then sellers of S&P components could up the prices at that time to exploit the mutual fund's trade strategy. Large traders are constantly trying to find ways to conceal their actual trading activity in order to avoid these exact problems. Finally, I feel obligated to note that it is important to keep in mind that trade frequency is linked to transactions costs – in general, the more frequently an investment manager (whether it be you or a mutual fund manager) executes trades, the more that manager will lose in transactions costs.\"", "title": "" }, { "docid": "280530", "text": "Most people carry a diversity of stock, bond, and commodities in their portfolio.

If you're investing for retirement you are definitely best to keep as much of your investment as possible in 401k or IRAs (preferably Roth IRAs). Many advisers suggest contributing as much to your 401k as your company matches, then the rest to IRA, and if you over contribute for the IRA back to the 401k. You may choose to skip the 401k if you are not comfortable with the choices your company offers in it (such as only investing in company stock). If you are investing for a point closer than retirement and you still want the risk (and reward potential) of stock I would suggest investing in low tax mutual funds, or eating the tax and investing in regular mutual funds.

I notice divided opinions among academics on the matter. W. Pfau gave a nice set of citations of papers with which he disagrees, so I'll start with them. In 1969, Paul Sameulson published the paper Lifetime Portfolio Selection By Dynamic Stochaistic Programming, which found that there's no mathematical foundation for an age based risk tolerance. There seems to be a fundamental quibble relating to present value of future wages; if they are stable and uncorrelated with the market, one analysis suggests the optimal lifecycle investment should start at roughly 300 percent of your portfolio in stocks (via crazy borrowing). Other people point out that if your wages are correlated with stock returns, allocations to stock as low as 20 percent might be optimal. So theory isn't helping much. Perhaps with the advent of computers we can find some kind of empirical data. Robert Shiller authored a study on lifecycle funds when they were proposed for personal Social Security accounts. Lifecycle strategies fare poorly in his historical simulation: Moreover, with these life cycle portfolios, relatively little is contributed when the allocation to stocks is high, since earnings are relatively low in the younger years. Workers contribute only a little to stocks, and do not enjoy a strong effect of compounding, since the proceeds of the early investments are taken out of the stock market as time goes on. Basu and Drew follow up on that assertion with a set of lifecycle strategies and their contrarian counterparts: whereas a the lifecycle plan starts high stock exposure and trails off near retirement, the contrarian ones will invest in bonds and cash early in life and move to stocks after a few years. They show that contrarian strategies have higher average returns, even at the low 25th percentile of returns. It's only at the bottom 5 or 10 percent where this is reversed. One problem with these empirical studies is isolating the effect of the glide path from rebalancing. It could be that a simple fixed allocation works plenty fine, and that selling winners and doubling down on losers is the fundamental driver of returns. Schleef and Eisinger compare lifecycle strategy with a number of fixed asset allocation schemes in Monte Carlo simulations and conclude that a 70% equity, 30% long term corp bonds does as well as all of the lifecycle funds. Finally, the earlier W Pfau paper offers a Monte Carlo simulation similar to Schleef and Eisinger, and runs final portfolio values through a utility function designed to calculate diminishing returns to more money. This seems like a good point, as the risk of your portfolio isn't all or nothing, but your first dollar is more valuable than your millionth. Pfau finds that for some risk-aversion coefficients, lifecycles offer greater utility than portfolios with fixed allocations. And Pfau does note that applying their strategies to the historical record makes a strong recommendation for 100 percent stocks in all but 5 years from 1940-2011.

This is also related to the question of mutual fund vs. ETF. First, a fund can be either actively managed or it can attempt to track an index. An actively managed fund has a fund manager who tries to find the best stocks to invest in within some constraints, like \"\"this fund invests in large cap US companies\"\". An index fund tries to match as closely as possible the performance of an index like the S&P 500. A fund may also try to offer a portfolio that is suitable for someone to put their entire account into. For example, a target date fund is a fund that may invest in a mix of stocks, bonds and foreign stock in a proportion that would be appropriate to someone expecting to retire in a certain year. These are not what people tend to think of as the canonical examples of mutual funds, even though they share the same legal structure and investment mechanisms. Secondly, a fund can either be a traditional mutual fund or it can be an exchange traded fund (ETF). To invest in a traditional mutual fund, you send money to the fund, and they give you a number of shares equal to what that money would have bought of the net asset value (NAV) of the fund at the end of trading on the day they receive your deposit, possibly minus a sales charge. To invest in an ETF, you buy shares of the ETF on the stock market like any other stock. Under the covers, an ETF does have something similar to the mechanism of depositing money to get shares, but only big traders can use that, and it's not used for investing, but only for people who are making a market in the stock (if lots of people are buying VTI, Big Dealer Co will get 100,000 shares from Vanguard so that they can sell them on the market the next day). Historically and traditionally, ETFs are associated with an indexing strategy, while if not specifically mentioned, people assume that traditional mutual funds are actively managed. Many ETFs, notably all the Vanguard ETFs, are actually just a different way to hold the same underlying fund. The best way to understand this is to read the prospectus for a mutual fund and an ETF.

The disadvantage to these funds is that the Target Fund charges its own expense ratio over and above the expense ratios charged by the mutual funds it invests in: you could do the same investments yourself (or pick your own mix and weighting of various funds) and save the extra expense ratio. However, over the years, as the Target Fund changes its mix, withdrawing money from the stock mutual funds and investing the proceeds into bond mutual funds, you do not have to pay taxes on the profits generated by these transactions except insofar as some part of the profits become distributions from the Target Fund itself.

Since it's more likely that you will need some of the money soon, and since you'll be cashing out said money in US Dollars, it's risky to have too much invested in foreign currencies. If you need money that's currently invested in a foreign currency and that currency happens to be doing poorly against USD at the moment, then you'll lose money simply because you need it now. This is the same rationale that goes into target-date funds' moving from stocks to bonds over time. Since the value of a stock portfolio has a lot more natural volatility than the value of a bond portfolio, if you're heavily invested in stocks when you need to withdraw money, there's a higher probability that you'll need to cash out just when stocks happen to be doing relatively poorly.

Also, the wording in your question suggests that your IRA investments have not done spectacularly well, and so it is reasonable to infer that your IRA is not a large amount, or at least not as large as what it would be 30 years from now. At this level of investment, it would be difficult for you to find a financial planner who spends all that much time looking after your interests. That you should get away from your current planner, presumably a mid-level employee in what is typically called the trust division of the bank, is a given. But, to go to another bank (or even to a different employee in the same bank), where you will also likely be nudged towards investing your IRA in CDs, annuities, and a few mutual funds with substantial sales charges and substantial annual expense fees, might just take you from the frying pan into the fire. You might want to consider transferring your IRA to a large mutual fund company and investing it in something simple like one of their low-cost (meaning small annual expense ratio) index funds. The Couch Potato portfolio suggests equal amounts invested in a no-load S&P 500 Index fund and a no-load Bond Index fund, or a 75%-25% split favoring the stock index fund (in view of your age and the fact that the IRA should be a long-term investment). But the point is, you can open an IRA account, have the money transferred from your IRA account with the bank, and make the investments on-line all by yourself instead of having a financial advisor do it on your behalf and charge you a fee for doing so (not to mention possibly screwing it up.) You can set up Automated Investment too; the mutual fund company will gladly withdraw money from your checking account and invest it in whatever fund(s) you choose. All this is not complicated at all. If you would like to follow the Couch Potato strategy and rebalance your portfolio once a year, you can do it by yourself too. If you want to invest in funds other than the S&P 500 Index fund, etc. most mutual fund companies offer a \"\"portfolio analysis\"\" and advice for a fee (and the fee is usually waived when the assets increase above certain levels - varies from company to company).

Many funds are already pretty diversified. If you buy a mutual fund, you are generally already getting a large portion of the gains from diversification. There is a very large difference between the unnecessary risk in your portfolio if you only hold a couple of stocks and if you hold a mutual fund. Should you be diversified across mutual funds as well? It depends on what your funds are. Many funds, such as target-date funds, are intended to be your sole investment. If you have funds covering every major asset class, then there may not be any additional benefit to buying other funds. You probably could not have picked your \"\"favorite fund\"\" early on. As humans, we have cognitive biases that make us think we knew things early on that we did not. I'm sure at some point at the very beginning you had a positive feeling toward that fund. Today you regret not acting on it and putting all your money there. But the number of such feelings is very large and if you acted on all those, you would do a lot of crazy and harmful things. You didn't know early on which fund would do well. You could just as well have had a good feeling about a fund that subsequently did much worse than your diversified portfolio did. The advice you have had about your portfolio probably isn't based on sound finance theory. You say you have always kept your investments in line with your age. This implies that you believe the guidelines given you by your broker or financial advisor are based in finance theory. Generally speaking, they are not. They are rules of thumb that seemed good to someone but are not rigorously proven either in theory or empirics. For example the notion that you should slowly shift your investments from speculative to conservative as you age is not based on sound finance theory. It just seems good to the people who give advice on such things. Nothing particularly wrong with it, I guess, but it's not remotely on par with the general concept of being well-diversified. The latter is extremely well established and verified, both in theory and in practice. Don't confuse the concept of diversification with the specific advice you have received from your advisor. A fund averaging very good returns is not an anomaly--at least going forward it will not be. There are many thousand funds and a large distribution in their historical performance. Just by random chance, some funds will have a truly outstanding track record. Perhaps the manager really was skilled. However, very careful empirical testing has shown the following: (1) You, me, and people whose profession it is to select outperforming mutual funds are unable to reliably detect which ones will outperform, except in hindsight (2) A fund that has outperformed, even over a long horizon, is not more likely to outperform in the future. No one is stopping you from putting all your money in that fund. Depending on its investment objective, you may even have decent diversification if you do so. However, please be aware that if you move your money based on historical outperformance, you will be acting on the same cognitive bias that makes gamblers believe they are on a \"\"hot streak\"\" and \"\"can't lose.\"\" They can, and so can you. ======== Edit to answer a more specific line of questions =========== One of your questions is whether it makes sense to buy a number of mutual funds as part of your diversification strategy. This is a slightly more subtle question and I will indicate where there is uncertainty in my answer. Diversifying across asset classes. Most of the gains from diversification are available in a single fund. There is a lot of idiosyncratic risk in one or two stocks and much less in a collection of hundreds of stocks, which is what any mutual fund will hold. Still,you will probably want at least a couple of funds in your portfolio. I will list them from most important to least and I will assume the bulk of your portfolio is in a total US equity fund (or S&P500-style fund) so that you are almost completely diversified already. Risky Bonds. These are corporate, municipal, sovereign debt, and long-term treasury debt funds. There is almost certainly a good deal to be gained by having a portion of your portfolio in bonds, and normally a total market fund will not include bond exposure. Bonds fund returns are closely related to interest rate and inflation changes. They are also exposed to some market risk but it's more efficient to get that from equity. The bond market is very large, so if you did market weights you would have more in bonds than in equity. Normally people do not do this, though. Instead you can get the exposure to interest rates by holding a lesser amount in longer-term bonds, rather than more in shorter-term bonds. I don't believe in shifting your weights toward nor away from this type of bond (as opposed to equity) as you age so if you are getting that advice, know that it is not well-founded in theory. Whatever your relative weight in risky bonds when you are young is should also be your weight when you are older. International. There are probably some gains from having some exposure to international markets, although these have decreased over time as economies have become more integrated. If we followed market weights, you would actually put half your equity weight in an international fund. Because international funds are taxed differently (gains are always taxed at the short-term capital gains rate) and because they have higher management fees, most people make only a small investment to international funds, if any at all. Emerging markets International funds often ignore emerging markets in order to maintain liquidity and low fees. You can get some exposure to these markets through emerging markets funds. However, the value of public equity in emerging markets is small when compared with that of developed markets, so according to finance theory, your investment in them should be small as well. That's a theoretical, not an empirical result. Emerging market funds charge high fees as well, so this one is kind of up to your taste. I can't say whether it will work out in the future. Real estate. You may want to get exposure to real estate by buying a real-estate fund (REIT). Though, if you own a house you are already exposed to the real estate market, perhaps more than you want to be. REITs often invest in commercial real estate, which is a little different from the residential market. Small Cap. Although total market funds invest in all capitalization levels, the market is so skewed toward large firms that many total market funds don't have any significant small cap exposure. It's common for individuals to hold a small cap fund to compensate for this, but it's not actually required by investment theory. In principle, the most diversified portfolio should be market-cap weighted, so small cap should have negligible weight in your portfolio. Many people hold small cap because historically it has outperformed large cap firms of equal risk, but this trend is uncertain. Many researchers feel that the small cap \"\"premium\"\" may have been a short-term artifact in the data. Given these facts and the fact that small-cap funds charge higher fees, it may make sense to pass on this asset class. Depends on your opinion and beliefs. Value (or Growth) Funds. Half the market can be classed as \"\"value\"\", while the other half is \"\"growth.\"\" Your total market fund should have equal representation in both so there is no diversification reason to buy a special value or growth fund. Historically, value funds have outperformed over long horizons and many researchers think this will continue, but it's not exactly mandated by the theory. If you choose to skew your portfolio by buying one of these, it should be a value fund. Sector funds. There is, in general, no diversification reason to buy funds that invest in a particular sector. If you are trying to hedge your income (like trying to avoid investing in the tech sector because you work in that sector) or your costs (buying energy because you buy use a disproportionate amount of energy) I could imagine you buying one of these funds. Risk-free bonds. Funds specializing in short-term treasuries or short-term high-quality bonds of other types are basically a substitute for a savings account, CD, money market fund, or other cash equivalent. Use as appropriate but there is little diversification here per se. In short, there is some value in diversifying across asset classes, and it is open to opinion how much you should do. Less well-justified is diversifying across managers within the same asset class.

You're obviously comfortable investing for the long-term, so you might get some benefit by spending a little time looking for different funds to increase your diversification. Note that ETFs don't really diversify any differently than mutual funds, they are just a different mechanism to invest in funds, and allow different trading strategies (trading during the day, derivatives, selling short, etc.).", "title": "" }, { "docid": "287991", "text": "I have about $1K in savings, and have been told that you should get into investment and saving for retirement early. I make around $200 per week, which about $150 goes into savings. That's $10k per year. The general rule of thumb is that you should have six months income as an emergency fund. So your savings should be around $5k. Build that first. Some argue that the standard should be six months of living expenses rather than income. Personally, I think that this example is exactly why it is income rather than living expenses. Six months of living expenses in this case would only be $1250, which won't pay for much. And note that living expenses can only be calculated after the fact. If your estimate of $50 a week is overly optimistic, you might not notice for months (until some large living expense pops up). Another problem with using living expenses as the measure is that if you hold down your living expenses to maximize your savings, this helps both measures. Then you hit your savings target, and your living expenses increase. So you need more savings. By contrast, if your income increases but your living expenses do not, you still need more savings but you can also save more money. Doesn't really change the basic analysis though. Either way you have an emergency savings target that you should hit before starting your retirement savings. If you save $150 per week, then you should have around $4k in savings at the beginning of next year. That's still low for an emergency fund by the income standard. So you probably shouldn't invest next year. With a living expenses standard, you could have $6250 in savings by April 15th (deadline for an IRA contribution that appears in the previous tax year). That's $5000 more than the $1250 emergency fund, so you could afford an IRA (probably a Roth) that year. If you save $7500 next year and start with $4k in savings (under the income standard for emergency savings), that would leave you with $11,500. Take $5500 of that and invest in an IRA, probably a Roth. After that, you could make a $100 deposit per week for the next year. Or just wait until the end. If you invested in an IRA the previous year because you decided use the living expenses standard, you would only have $6500 at the end of the year. If you wait until you have $6750, you could max out your IRA contribution. At that point, your excess income for each year would be larger than the maximum IRA contribution, so you could max it out until your circumstances change. If you don't actually save $3k this year and $7500 next year, don't sweat it. A college education is enough of an investment at your age. Do that first, then emergency savings, then retirement. That will flip around once you get a better paying, long term job. Then you should include retirement savings as an expected cost. So you'd pay the minimum required for your education loans and other required living expenses, then dedicate an amount for retirement savings, then build your emergency savings, then pay off your education loans (above the minimum payment). This is where it can pay to use the more aggressive living expenses standard, as that allows you to pay off your education loans faster. I would invest retirement savings in a nice, diversified index fund (or two since maintaining the correct stock/bond mix of 70%-75% stocks is less risky than investing in just bonds much less just stocks). Investing in individual stocks is something you should do with excess money that you can afford to lose. Secure your retirement first. Then stock investments are gravy if they pan out. If they don't, you're still all right. But if they do, you can make bigger decisions, e.g. buying a house. Realize that buying individual stocks is about more than just buying an app. You have to both check the fundamentals (which the app can help you do) and find other reasons to buy a stock. If you rely on an app, then you're essentially joining everyone else using that app. You'll make the same profit as everyone else, which won't be much because you all share the profit opportunities with the app's system. If you want to use someone else's system, stick with mutual funds. The app system is actually more dangerous in the long term. Early in the app's life cycle, its system can produce positive returns because a small number of people are sharing the benefits of that system. As more people adopt it though, the total possible returns stay the same. At some point, users saturate the app. All the possible returns are realized. Then users are competing with each other for returns. The per user returns will shrink as usage grows. If you have your own system, then you are competing with fewer people for the returns from it.

Unit investment trusts made of bonds do have a maturity date as well, since the portfolio does not change once the UIT is issued.

This deduction can reduce the amount of your income subject to tax by up to $2,500. Read the whole document to be sure, but that's the basics.

If I have $1 but can loan out $30, and anything more than $1 gets paid back, I haven't lost any money. In addition, I can write off the amount defaulted, *and the government will pay me back* for certain types of loans. With student loans, since they are almost impossible to discharge, gov't will pursue the borrower for years and decades, and ultimately collect more interest. Here is an article on it: http://online.wsj.com/article/SB10001424052748704723104576061953842079760.html &gt; According to Kantrowitz, the government stands to earn $2,010.44 more in interest from a $10,000 loan that defaulted than if it had been paid in full over a 20-year term, and $6,522.00 more than if it had been paid back in 10 years. Alan Collinge, founder of borrowers' rights advocacy Student Loan Justice, said the high recovery rates provide a \"\"perverted incentive\"\" for the government to allow loans to go into default. Kantrowitz estimates the recovery rate would need to fall to below 50% in order for default prevention efforts to become more lucrative than defaults themselves. Not to mention: http://studentloanjustice.org/defaults-making-money.html &gt; So essentially, the Department is given a choice: Either do nothing and get nothing, or outlay cash with the knowledge that this outlay will realize a 22 percent return, ultimately (minus the governments cost of money and collection costs). From this perspective, it is clear that based solely on financial motivations, and without specific detailed knowledge of the loan (i.e. borrower characteristics, etc.), the chooser would clearly favor the default scenario, for not only the return, but perhaps the potential savings in subsidy payment as well, And don't forget the penalties accruing to the person defaulting; they will probably have to move out of the country in order to escape collection. And let's factor in the huge ROI the lender sees by creating an indentured servant class. Plus, the gov't will issue as much currency as it wants, to make *itself* whole. And how much of a loss IS the loss, when the whole of the loan amount went right back into the local economy, paying professors, janitors, landlords, grocery stores, etc.? And don't forget all THOSE taxes (income and sale) that the gov't collects. Government will collect ~30%-50% of the loan immediately as income and sales tax, plus a portion of it every time the money changes hands (I pay income tax, then use some of my after-tax money to pay you for a product or service, and you still have to pay tax on that money, and so on). So it's more complicated than having \"\"robbed the person holding the debt\"\". Banks at 30x leverage don't lose money as long as they get back 1/30th of the total amount lent out, including interest, fees, and penalties, before considering write-offs and government repayment. In fact, the point of over-leverage is so you CAN make loans that have risk attached. If you could only lend what you actually had, you would have to stay away from anything risky because it would be too easy to lose money. Having virtual $ to bet means you can serve market segments that have higher risk. This makes MORE money for the banks, that's why they do it. They are already playing with funny money, so they don't lose any even if you default and move to another country. And the money you \"\"spent\"\" has also made its way back to them in various amounts, such as your professor's mortgage payments, auto loan, etc. Your taking on debt already helped the bank get its OTHER loans repaid. So, roughly speaking, if you took out $90,000 and $3,000 of that made its way back to the bank through various means, they haven't lost any money, because it only cost them $3,000 actual dollars in the first place.\"", "title": "" }, { "docid": "509075", "text": "I have a CapitalOne credit card, and every two or three weeks, CapitalOne Bank sends me checks that can be used almost anywhere (including a deposit into my own checking account if I wish, or to pay taxes or utility bills etc)).

The CPA should provide guarantee that based on the documents you provided, he filled all the necessary forms correctly, and will absorb all the fees and penalties if there's an audit and mistakes were found not because you withheld information from your CPA, but because the CPA made a mistake.

You are also building equity (instead of helping your landlord build his or her equity). Take for example a single person paying $1,000/month to rent an apartment. This is not deductible. He has $1,800 a year in other expenditures that would otherwise be deductible (charitable contributions, etc.), but he doesn't itemize because it isn't more than the $6,100 standard deduction, so it doesn't matter. He takes out a mortgage for $150,000 at 6% over a 30-year term to buy a similarly-appointed home. His new mortgage payment is about $900/month, plus he puts $100/month into an escrow account for property taxes, roughly totaling his former rent payment. Over the first full year, he pays about $9,000 in deductible mortgage interest and $1,200 in deductible real estate taxes.

My main question is with how far away it is (over 1000 miles), how do I quantify the travel expenses? Generally, \"\"necessary and ordinary\"\" expenses are deductible. This is true for business and also true for rentals. But what is necessary and what is ordinary? Is it ordinary that a landlord will manage the property 1000 miles away by himself on a daily basis? Is it ordinary for people to drive 1000 miles every week? I'd say \"\"no\"\" to both. I'd say it would be cheaper for you to hire a local property manager, thus the travel expense would not be necessary. I would say it would be cheaper to fly (although I don't know if its true to the specific situation of the OP, but as I said - its too localized to deal with) rather than drive from Texas to Colorado. If the OP thinks that driving a thousand miles is indeed ordinary and necessary he'll have to justify it to the IRS examiner, as I'm sure it will be examined. 2 trips to the property a year will be a nearly 100% write-off (2000 miles, hotels, etc). From what I understood (and that is what I've been told by my CPA), IRS generally allows 1 (one) trip per year per property. If there's an exceptional situation - be prepared to justify it. Also, keep all the receipts (like gas, hotel, etc.... If you claim mileage but in reality you took a flight - you'll get hit hard by the IRS when audited). Also while I'm up there am I allowed to mix business with pleasure? You cannot deduct personal (\"\"pleasure\"\") expenses, at all. If the trip is mainly business, but you go out at the evening instead of staying at the hotel - that's fine. But if the trip is \"\"business\"\" trip where you spend a couple of hours at your property and then go around having fun for two days - the whole trip may be disallowed. If there's a reasonable portion dedicated to your business/rental, and the rest is pleasure - you'll have to split some of the costs and only deduct the portion attributed to the business activities. You'll have to analyze your specific situation, and see where it falls. Don't stretch the limits too much, it will cost you more on the long run after all the audits and penalties. Can I also write off all travel involved in the purchase of the property? Although, again, the \"\"necessary and ordinary\"\" justification of such a trip is arguable, lets assume it is necessary and ordinary and generally justified. It is reasonable to expect you to go and see the property with your own eyes before the closing (IMHO, of course, I'm not an authority). Such an expense can be either business or investment expense.

To a younger person, the Roth (either Roth 401(k) or IRA) is a good choice while you are in a lower tax bracket. I recommend you look at the page at Fairmark to understand the tax brackets.

They use credit for their day-to-day expenses and pay it off from the dividends on their investments (which might only come in once a quarter). There are also tax advantages to using credit. If a rich person wanted a new car, he'd be smarter leasing it for his business (immediate write-off of the lease payments on taxes) versus buying it (depreciation over several years plus property tax liability in some states). There are more elaborate tax dodges but the point is that buying a car outright is the worst option in terms of tax avoidance. Another way the rich (mis) use credit is so that they don't risk their own money on business ventures.

Set up a separate checking account just for rent and utilities, put a month's worth of cash in there, and have another payroll deduction that covers your living expenses + maybe 5% put in there automatically.

[ { "docid": "539958", "text": "\"Government registering of financial institutions usually is to make the government safe (eg FINTRAC is watching for money laundering and financing terrorism) rather than to make it's customers safe. Most governments have many levels of registrations and regulatory bodies. The most stringent requirements are usually obligatory only for banks, and they indeed often include precautions for insuring customer's deposits. Even this insurances have limits, eg in most EU countries the state guarantees deposits up to 100kEUR. If you deposit more and the bank flops - you lose everything over the limit. Companies like forex or currency exchanges usually make their best effort to avoid as many regulations as possible, just because it's costly. If a given company does have guarantee funds and/or customer insurance, it should be advertised and explained on their website. However the whole issue of trust is misguiding. You don't have to \"\"trust\"\" in your grocery store to shop there. There is no government guarantee that the vegetables sold will be tasty. If you buy and the product fells short of your expectations, you call it a loss and start shopping elsewhere. Financial services are no different than any other product. I recommend to your aunt to start small and see how it works. If a service turns out well, she can increase the amount sent through exchange and decrease amount sent through bank. But still, it's always prudent to send eg $1000 every week instead of $4000 once a month. It's more time consuming and cumbersome than having your bank do it - but it's the safety and convenience you're paying premium for.\"", "title": "" } ]

(I identify this fund because I know it exists, not because I particularly recommend it.) Your money will be in Canadian currency earning Canadian interest rates. You will pay a small portion of that interest in fees. Since US banks are already guaranteed by the FDIC up to $250,000 per account, I don't really think you avoid any risks associated with the failure of an individual bank, but you might fare better if the US currency is subject to inflation or unfavorable foreign-exchange movements - not that such a thing would be a direct risk of a bank failure, but it could happen as a result of actions taken by the Federal Reserve under the auspices of aiding the economy if the economy worsens in the wake of a financial crisis - or, for that matter, if it worsens as a result of something else, including legislative, regulatory, or executive policies. Read the prospectus to understand additional risks with this investment. One of them is foreign-exchange risk.

You can hold individual shares, including ETFs, traded on any \"\"designated stock exchange\"\" in addition to the other types of investment you have listed. Here is a list of designated stock exchanges provided by the Department of Finance. As you can see, it includes pretty well every major stock exchange in the developed world. If your bank's TFSA only offers \"\"mutual funds, GICs and saving deposits\"\" then you need to open a TFSA with a different bank or a stock broking company with an execution only service that offers TFSA accounts. Almost all of the big banks will do this. I use Scotia iTrade, HSBC Invest Direct, and TD, though my TFSA's are all with HSBC currently. You will simply provide them with details of your bank account in order to facilitate money transfers/TFSA contributions. Since purchasing foreign shares involves changing your Canadian dollars into a foreign currency, one thing to watch out for when purchasing foreign shares is the potential for high foreign exchange spreads. They can be excessive in proportion to the investment being made. My experience is that HSBC offers by far the best spreads on FX, but you need to exchange a minimum of $10,000 in order to obtain a decent spread (typically between 0.25% and 0.5%). You may also wish to note that you can buy unhedged ETFs for the US and European markets on the Toronto exchange. This means you are paying next to nothing on the spread, though you obviously are still carrying the currency risk. For example, an unhedged S&P500 trades under the code ZSP (BMO unhedged) or XUS (iShares unhedged). In addition, it is important to consider that commissions for trades on foreign markets may be much higher than those on a Canadian exchange. This is not always the case. HSBC charge me a flat rate of $6.88 for both Toronto and New York trades, but for London they would charge up to 0.5% depending on the size of the trade. Some foreign exchanges carry additional trading costs. For example, London has a 0.5% stamp duty on purchases. EDIT One final thing worth mentioning is that, in my experience, holding US securities means that you will be required to register with the US tax authorities and with those US exchanges upon which you are trading. This just means fill out a number of different forms which will be provided by your stock broker. Exchange registrations can be done electronically, however US tax authority registration must be submitted in writing. Dividends you receive will be net of US withholding taxes.

However, that cost is insignificant compared to your possible losses on the currency exchange. Assuming your money is currently in Hong Kong Dollars (HKD), it will need to be converted to US Dollars (USD). One place where it could be converted is at your Hong Kong bank. You'll get their retail rate. Make sure you are aware of the rate they will use, and any fees, in advance. Expect to pay around 2-3% from the mid-market rate (the rate you see quoted online, which doesn't fluctuate much for HKD-USD as the currencies are linked). Another place where the currency could be converted is at your US bank. You really don't get any control over that if it arrives as HKD and is then automatically converted into your USD. The rate and fees could be quite poor, especially if it is a minor US bank that has to deal with anther bank for foreign currency. For amounts of this size, it's worthwhile using a specialist currency conversion company instead. Currency Fair in Ireland is one. It's a peer-to-peer exchange that is generally the best deal (at least for the currency pairs I use). You wire the money to them, do the exchange on their site at a rate that is much closer to 0.5% from the midrate, then the money is transferred out by wire for a few dollars. Adds a few days to the process, but will possibly save you close to US$1000. Another established option is Currency Online in New Zealand.

Countries like Iran or Venezuela, with a managed exchange rate, set their exchange rates at a higher value than the market accepts. Such market expectations may be influenced by poor government management, interventions into markets (such as nationalising businesses) or general instability / scarcity. The governments act to manage that uncertainty by limiting the availability of foreign exchange and pegging the exchange rate. Since there is an inadequate supply of trusted foreign currency people turn to informal exchanges in order to hedge their currency risk. This creates a negative feedback loop. People in government who have access to foreign exchange start to trade on informal markets, pocketing the difference in the official and unofficial rates. The increasing gap between the two rates drives increasing informal market exchange and can result in speculative bubbles. Driving instability (or economic contradiction) is that the massive and increasing difference between the official and market exchange rates becomes a powerful form of rent for government officials. This drives further state-led rent-seeking behaviour and causes the economy to become even more unstable.

I just want to place it somewhere and let it grow Your intuition is spot on! To buy & hold is the sensible thing to do. There is no need to constantly monitor the stock market. To invest successfully you only need some basic pointers. People make it look like it's more complicated than it actually is for individual investors. You might find useful some wisdom pearls I wish I had learned even earlier. Stocks & Bonds are the best passive investment available. Stocks offer the best return, while bonds are reduce risk. The stock/bond allocation depends of your risk tolerance. Since you're as young as it gets, I would forget about bonds until later and go with a full stock portfolio. Banks are glorified money mausoleums; the interest you can get from them is rarely noticeable. Index investing is the best alternative. How so? Because 'you can't beat the market'. Nobody can; but people like to try and fail. So instead of trying, some fund managers simply track a market index (always successfully) while others try to beat it (consistently failing). Actively managed mutual funds have higher costs for the extra work involved. Avoid them like the plague. Look for a diversified index fund with low TER (Total Expense Ratio). These are the most important factors. Diversification will increase safety, while low costs guarantee that you get the most out of your money. Vanguard has truly good index funds, as well as Blackrock (iShares). Since you can't simply buy equity by yourself, you need a broker to buy and sell. Luckily, there are many good online brokers in Europe. What we're looking for in a broker is safety (run background checks, ask other wise individual investors that have taken time out of their schedules to read the small print) and that charges us with low fees. You probably can do this through the bank, but... well, it defeats its own purpose. US citizens have their 401(k) accounts. Very neat stuff. Check your country's law to see if you can make use of something similar to reduce the tax cost of investing. Your government will want a slice of those juicy dividends. An alternative is to buy an index fund on which dividends are not distributed, but are automatically reinvested instead.

If India wants to buy an F-16s, at cost $34M USD, they'll have to actually acquire $34M USD, or else convince the seller to agree to a different currency. They would acquire that $34M USD in a few possible ways. One of which is to exchange INR (India Rupees) at whatever the current exchange rate is, to whomever will agree to the opposite - i.e., someone who has USD and wants INR, or at least is willing to be the middleman. Another would be to sell some goods or services in the US (for USD), or to someone else for USD. Indian companies undoubtedly do this all the time. Think of all of those H1B workers that are in the news right now; they're all earning USD and then converting those to INRs. So the Indian government can just buy their USD for INR, directly or more likely indirectly (through a currency exchange market). A third method would be to use some of their currency stores. Most countries have significant reserves of various foreign currencies on hand, for two reasons: one to simplify transactions like this one, and also to stabilize the value of their own currency. A less stable currency can be stabilized simply by the central bank of that country owning USD, EUR, Pounds Sterling, or similar stable-value currencies.

Investopedia defines a currency forward as follows (with a few key points emphasized): [A currency forward is] a binding contract in the foreign exchange market that locks in the exchange rate for the purchase or sale of a currency on a future date. A currency forward is essentially a hedging tool that does not involve any upfront payment. The other major benefit of a currency forward is that it can be tailored to a particular amount and delivery period, unlike standardized currency futures. This can be a major advantage for planning and risk management purposes. For example, if I know I'm going to have to pay $1 million USD in the future and most of my revenue is in Euros, the actual amount I'll have to pay will vary based on the exchange rate between Euros and dollars. Thus, it's very worthwhile for me to be able to \"\"lock in\"\" a particular exchange rate so that I know exactly how much I'm going to pay relative to my projected revenue. The goal isn't necessarily to make money off the transaction (maybe they do, maybe they don't) as much as to reduce risk and improve planning ability. The fact that it doesn't involve an up-front payment is also a major advantage. It's usually a bad practice to \"\"sit on\"\" cash for a year if you can avoid it. Another key point: savings accounts pay less interest than inflation. If inflation is 3% and your savings account pays 1%, that looks remarkably like a guaranteed 2% loss to me.\"", "title": "" }, { "docid": "93518", "text": "\"It may seem weird but interest rates are set by a market. Risk is a very large component of the price that a saver will accept to deposit their money in a bank but not the only one. Essentially you are \"\"lending\"\" deposited cash to the bank that you put it in and they will lend it out at a certain risk to themselves and a certain risk to you. By diversifying who they lend to (corporations, home-buyers each other etc.) the banks mitigate a lot of the risk but lending to the bank is still a risky endeavour for the \"\"saver\"\" and the saver accepts a given interest rate for the amount of risk there is in having the money in that particular bank. The bank is also unable to diversify away all possible risk, but tries to do the best job it can. If a bank is seen to take bigger risks and therefore be in greater risk of failing (having a run on deposits) it must have a requisitely higher interest rates on deposits compared to a lower risk bank. \"\"Savers\"\" therefore \"\"shop around\"\" for the best interest rate for a given level of risk which sets the viable interest rate for that bank; any higher and the bank would not make a profit on the money that it lends out and so would not be viable as a business, any lower and savers would not deposit their money as the risk would be too high for the reward. Hence competition (or lack of it) will set the rate as a trade off between risk and return. Note that governments are also customers of the banking industry when they are issuing fixed income securities (bonds) and a good deal of the lending done by any bank is to various governments so the price that they borrow money at is a key determinant of what interest rate the bank can afford to give and are part of the competitive banking industry whether they want to be or not. Since governments in most (westernised) countries provide insurance for deposits the basic level of (perceived) risk for all of the banks in any given country is about the same. That these banks lend to each other on an incredibly regular basis (look into the overnight or repo money market if you want to see exactly how much, the rates that these banks pay to and receive from each other are governed by interbank lending rates called Libor and Euribor and are even more complicated than this answer) simply compounds this effect because it makes all of the banks reliant on each other and therefore they help each other to stay liquid (to some extent). Note that I haven't mentioned currency at all so far but this market in every country applies over a number of currencies. The way that this occurs is due to arbitrage; if I can put foreign money into a bank in a country at a rate that is higher than the rate in its native country after exchange costs and exchange rate risk I will convert all of my money to that currency and take the higher interest rate. For an ordinary individual's savings that is not really possible but remember that the large multinational banks can do exactly the same thing with billions of dollars of deposits and effectively get free money. This means that either the bank's interest rate will fall to a risk adjusted level or the exchange rate will move. Either of those moves will remove the potential for making money for nothing. In this case, therefore it is both the exchange rate risk (and costs) as well as the loan market in that country that set the interest rate in foreign currencies. Demand for loans in the foreign currency is not a major mover for the same reason. Companies importing from foreign entities need cash in foreign currencies to pay their bills and so will borrow money in other currencies to fulfil these operations which could come from deposits in the foreign currency if they were available at a lower interest rate than a loan in local currency plus the costs of exchange but the banks will be unwilling to loan to them for less than the highest return that they can get so will push up interest rates to their risk level in the same way that they did in the market before currencies were taken into account. Freedom of movement of foreign currencies, however, does move interest rates in foreign currencies as the banks want to be able to lend as much of currencies that are not freely deliverable as they can so will pay a premium for these currencies. Other political moves such as the government wanting to borrow large amounts of foreign currency etc. will also move the interest rate given for foreign currencies not just because loaning to the government is less risky but also because they sometimes pay a premium (in interest) for being able to borrow foreign currency which may balance this out. Speculation that a country may change its base interest rate will move short term rates, and can move long term rates if it is seen to be a part of a country's economic strategy. The theory behind this is deep and involved but the tl;dr answer would be the standard \"\"invisible hand\"\" response when anything market or arbitrage related is involved. references: I work in credit risk and got a colleague who is also a credit risk consultant and economist to look over it.

An individual might have on the order of $1,000 - $10,000 in such an account; for a bank, that's basically chump change, and you are looking more at numbers in the millions of dollars range. Sometimes a lot more than that. For a large bank, even hundreds of millions of dollars might be a relatively small portion of their holdings. The 2011 Goldman Sachs annual report (I just pulled a big bank out of thin air, here; no affiliation with them that I know of) states that as of December 2011, their excess liquidity was 171,581 million US dollars (over 170 billion dollars), with a bottom line total assets of $923,225 million (a shade under a trillion dollars) book value. Good luck finding a bank that will pay you 4% interest on even a fraction of such an amount. GS' income before tax in 2011 was a shade under 6.2 billion dollars; 4% on 170 billion dollars is 6.8 billion dollars. That is, the interest payments at such a rate on their excess liquidity alone would have cost more than they themselves made in the entire year, which is completely unsustainable. Government bonds are as guaranteed as deposit-insurance-covered bank accounts (it'll be the government that steps in and pays the guaranteed amount, quite possibly issuing bonds to cover the cost), but (assuming the country does not default on its debt, which happens from time to time) you will get back the entire amount plus interest. For a deposit-insured bank account of any kind, you are only guaranteed (to the extent that one can guarantee anything) the maximum amount in the country's bank deposit insurance; I believe in most countries, this is at best on the order of $100,000. If the bank where the money is kept goes bankrupt, for holdings on the order of what banks deal with, you would be extremely lucky to recover even a few percent of the principal. Government bonds are also generally accepted as collateral for the bank's own loans, which can make a difference when you need to raise more money in short order because a large customer decided to withdraw a big pile of cash from their account, maybe to buy stocks or bonds themselves. Government bonds are generally liquid. That is, they aren't just issued by the government, held to maturity while paying interest, and then returned (electronically, these days) in return for their face value in cash. Government bonds are bought and sold on the \"\"secondary market\"\" as well, where they are traded in very much the same way as public company stocks. If banks started simply depositing money with each other, all else aside, then what would happen? Keep in mind that the interest rate is basically the price of money. Supply-and-demand would dictate that if you get a huge inflow of capital, you can lower the interest rate paid on that capital. Banks don't pay high interest (and certainly wouldn't do so to each other) because of their intristic good will; they pay high interest because they cannot secure capital funding at lower rates. This is a large reason why the large banks will generally pay much lower interest rates than smaller niche banks; the larger banks are seen as more reliable in the bond market, so are able to get funding more cheaply by issuing bonds. Individuals will often buy bonds for the perceived safety. Depending on how much money you are dealing with (sold a large house recently?) it is quite possible even for individuals to hit the ceiling on deposit insurance, and for any of a number of reasons they might not feel comfortable putting the money in the stock market. Buying government bonds then becomes a relatively attractive option -- you get a slightly lower return than you might be able to get in a high-interest savings account, but you are virtually guaranteed return of the entire principal if the bond is held to maturity. On the other hand, it might not be the case that you will get the entire principal back if the bank paying the high interest gets into financial trouble or even bankruptcy. Some people have personal or systemic objections toward banks, limiting their willingness to deposit large amounts of money with them. And of course in some cases, such as for example retirement savings, it might not even be possible to simply stash the money in a savings account, in which case bonds of some kind is your only option if you want a purely interest-bearing investment.\"", "title": "" }, { "docid": "538843", "text": "What you are doing is barter trade.

Q: What factors are behind why currencies go up or down? A: Just like any open market, currencies go up and down based on supply and demand. Many factors affect the supply and demand of a particular currency. Some were listed well by the other posts. Q: What roles do governments, central banks, institutions, and traders have in the process? A: It's common practice that gov'ts intervene to \"\"control\"\" the value of currencies. For example, although it's not general public knowledge, the Canadian gov't is actively purchasing up US dollars in the FX market in an effort to stop the US/Canadian exchange rate from dropping further.

Depending on your circumstances, this might be more cost effective than purchasing US-listed ADRs. One such broker is Interactive Brokers, which allows US citizens to directly purchase shares on many different foreign exchanges using their online platform (including in France). For France, I believe their costs are currently 0.1% of the total trade value with a 4€ minimum. I should warn you that the IB platform is not particularly user-friendly, since they market themselves to traders and the learning curve is steep (although accounts are available to individual investors). IB also won't automatically convert currencies for you, so you also need to use their foreign exchange trading interface to acquire the foreign currency used to purchase a foreign stock, which has plusses and minuses. On the plus side, their F/X spread is very competitive, but the interface is, shall we say, not very intuitive. I can't answer question #2 with specific regards to US/France. At least in the case of IB, though, I believe any dividends from a EUR-denominated stock would continue to accumulate in your account in Euros until you decide to convert them to dollars (or you could reinvest in EUR if you so choose).", "title": "" }, { "docid": "72375", "text": "\"I think your best bet here would be HSBC.

Regarding fees, I suspect you will need to be a \"\"Premier Account\"\" holder in order to avoid any fees imposed on transactions such as money transfers and exchanging money between currencies. In my experience HSBC offers extremely good exchange rates when exchanging \"\"large\"\" amounts of money ( greater than $10,000 / GBP 5,000 ). Exchanging small amounts will carry a larger spread but still much better than most banks offer. In my experience, exchanging GBP 5000 will have a spread of about 0.50-to-0.75 percent, while exchanging more than GBP10,000 will have a spread of as little as 0.10-to-0.20 percent. In order to qualify for a \"\"Premier Account\"\", if my memory of HSBC UK serves me correctly, you will need to have at least GBP 50,000 net across all of your HSBC managed accounts, including stockbroking and other investment accounts. In order to open a banking Swiss account, you will need to travel to Switzerland and apply in person. You cannot open a foreign bank account remotely. With a foreign investment account, I believe you can open accounts remotely. For example, I opened an account with Fidelity Switzerland using my Fidelity UK account directly from the UK, however obviously Fidelity does not provide banking services so this is not of interest to you. The simplest thing to do is to visit your local HSBC branch and discuss it with them in person. Other UK banks, such as Barclays, will also provide such services, but in my experience they are not as competitive on fees.\"", "title": "" }, { "docid": "92462", "text": "Are there banks where you can open a bank account without being a citizen of that country without having to visit the bank in person?

German online banks for instance allow you to administrate anything online, should there be cards issued you would need an address in the country. And for opening an account a passport is sufficient, you can identify yourself in a video chat. Now what's the downside? French banks' online services are in French, German banks' services are in German. If that doesn't put you off, I would name such banks in the comments if asked. Are there any online services for investing money that aren't tied to any particular country? Can you clarify that? You should at least be able to buy into any European or American stock through your broker. That should give you an ease of mind being FCA-regulated.

METHODS: Analysis of major tobacco industries' internal secret documents on cigarette radioactivity made available online by the Master Settlement Agreement in 1998. RESULTS: The documents show that the industry was well aware of the presence of a radioactive substance in tobacco as early as 1959. Furthermore, the industry was not only cognizant of the potential \"cancerous growth\" in the lungs of regular smokers but also did quantitative radiobiological calculations to estimate the long-term (25 years) lung radiation absorption dose (rad) of ionizing alpha particles emitted from the cigarette smoke. Our own calculations of lung rad of alpha particles match closely the rad estimated by the industry. According to the Environmental Protection Agency, the industry's and our estimate of long-term lung rad of alpha particles causes 120-138 lung cancer deaths per year per 1,000 regular smokers. Acid wash was discovered in 1980 to be highly effectively in removing (210)Po from the tobacco leaves; however, the industry avoided its use for concerns that acid media would ionize nicotine converting it into a poorly absorbable form into the brain of smokers thus depriving them of the much sought after instant \"nicotine kick\" sensation.

Results from studies spanning nearly 5 decades show that (210)Po concentrations in organisms vary widely among the different phylogenic groups as well as between the different tissues of a given species. Such variation results in (210)Po concentration factors ranging from approximately 10(3) to over 10(6) depending upon the organism or tissue considered. (210)Po/(210)Pb ratios in marine species are generally greater than unity and tend to increase up the food chain indicating that (210)Po is preferentially taken up by organisms compared to its progenitor (210)Pb. The effective transfer of (210)Po up the food chain is primarily due to the high degree of assimilation of the radionuclide from ingested food and its subsequent strong retention in the organisms. In some cases this mechanism may lead to an apparent biomagnification of (210)Po at the higher trophic level. Various pelagic species release (210)Po and (210)Pb packaged in organic biodetrital particles that sink and remove these radionuclides from the upper water column, a biogeochemical process which, coupled with scavenging rates of this radionuclide pair, is being examined as a possible proxy for estimating downward organic carbon fluxes in the sea. Data related to preferential bioaccumulation in various organisms, their tissues, resultant radiation doses to these species, and the processes by which (210)Po is transferred and recycled through the food web are discussed. In addition, the main gaps in our present knowledge and proposed areas for future studies on the biogeochemical behaviour of (210)Po and its use as a tracer of oceanographic processes are highlighted in this review.

In an effort to better understand consumer attitudes about nutrition and to explore alternatives for communicating dietary advice in language that is meaningful and motivates behavior change, the International Food Information Council (IFIC) conducted qualitative research with consumers (using focus groups) and registered dietitians (using telephone interviews) in 1998 and 1999. Results of the research are presented using dietary fat as a case study. Findings from the IFIC research were reported to the Dietary Guidelines Advisory Committee to assist the Committee in developing meaningful and action-oriented dietary advice related to dietary fat for inclusion in the 2000 Dietary Guidelines for Americans that would be motivating and easy for consumers to implement. The recommendation to moderate fat intake in the new dietary guideline, \"Choose a diet that is low in saturated fat and cholesterol and moderate in total fat\" is consistent with communication recommendations in the IFIC research. Further, the moderate fat message is empowering because it suggests an achievable dietary regimen and reduces guilt and worry about foods. It allows flexibility to enjoy desired foods and promotes using common sense when it comes to diet. Several issues emerged from the IFIC research that apply to general nutrition communications with consumers, whether it be through national nutrition recommendations or in one-on-one counseling situations: to be effective, messages to consumers about nutrition, and specifically dietary fat, must address sources of discomfort about dietary choices; they must engender a sense of empowerment; and they should motivate both by providing clear information that propels toward taking action and appeals to the need to make personal choices.", "title": "Developing actionable dietary guidance messages: dietary fat as a case study." }, { "docid": "MED-2251", "text": "The ubiquitous food contaminant cadmium has features of an estrogen mimetic that may promote the development of estrogen-dependent malignancies, such as breast cancer.

DESIGN: A controlled, 6-mo trial was conducted in 57 PCOS women.

RESULTS: Seven women dropped out because of pregnancy, 23 women dropped out because of other reasons, and 27 women completed the study.

OBJECTIVES: In a prospective population-based study, we investigated whether a higher intake of whole grain protects against the development of prediabetes and T2D and tested for modulation by polymorphisms of the TCF7L2 gene. DESIGN: We examined the 8-10-y incidence of prediabetes (impaired glucose tolerance, impaired fasting glucose, or the combination of both) and T2D in relation to the intake of whole grain. Baseline data were available for 3180 women and 2297 men aged 35-56 y.

Serum samples were obtained from eight overweight men before and after the Pritikin residential, 2-week diet and exercise intervention and from seven men who were long-term followers of the low-fat, high-fiber diet and regular exercise lifestyle. The serum was used to stimulate primary prostate epithelial cells in culture. Growth was measured after 48 and 96 h and apoptosis after 96 h. At 48 h there was no significant difference in growth within the Pre, 2-week or Long-Term groups. At 96 h growth was significantly reduced in the 2-week (13%) and in the Long-Term (14%) groups compared to the Pre data. At 96 h, apoptosis was not significantly different among the three groups. Fasting insulin was reduced by 30% in the 2-week group and by 52% in the Long-Term group compared to the Pre data. Testosterone was unchanged in the 2-week group.

Serum concentrations of several polychlorinated biphenyls (PCBs), and the pesticides hexachlorobenzene (HCB), β-hexachlorocyclohexane (β-HCH), chlordane compounds and dichlorodiphenyldichloroethylene (DDE) were determined by liquid-liquid extraction, silica column cleanup and gas chromatography high resolution mass spectrometry. Diet was assessed using 4-day food records and complementary dietary and lifestyle factors by questionnaire. Fish intake was additionally assessed by plasma fatty acid composition. Clustering of the compounds revealed that PCBs were separated into two clusters, one including low-chlorinated PCB 28 and 52, and the other high-chlorinated mono- and di-ortho PCBs, suggesting similarities and dissimilarities in exposure sources and possibly also toxicokinetics. Men had 24% and 32% higher levels of PCB 138-180 and chlordane compounds, respectively, compared with women.

Researchers have associated factors such as the Western diet, obesity, alcohol consumption, and smoking with risk of AD. OBJECTIVE: This paper evaluates whether the dietary transition might explain the rising trend of AD prevalence in Japan and in developing countries, evaluating other factors when possible. METHODS: This study used two approaches to see whether dietary or other changes could explain AD trends in Japan and developing countries. One approach involved comparing trends of AD in Japan with changes in national dietary supply factors, alcohol consumption, and lung cancer mortality rates from zero to 25 years before the prevalence data. The second compared AD prevalence values for eight developing countries with dietary supply factors from zero to 25 years before the prevalence data. RESULTS: For Japan, alcohol consumption, animal product, meat and rice supply, and lung cancer rates correlated highly with AD prevalence data, with the strongest correlation for a lag of 15-25 years. In the eight-country study, total energy and animal fat correlated highly with AD prevalence data, with a lag of 15-20 years. Mechanisms to explain the findings include increased obesity for the eight countries, and increases in cholesterol, saturated fat, and iron from increases in animal products and meat supply for Japan.

Detection of the latter requires that the menstrual cycle be monitored, but may help prevent recruitment bias in studies comparing vegetarians with nonvegetarians because vegetarians with menstrual disturbances may be more likely to volunteer for a study on menstrual disturbances and vegetarianism. Three general mechanisms that could contribute to menstrual disturbances that may differ between vegetarians and nonvegetarians include energy imbalances associated with body-weight disturbances or exercise, psychosocial and cognitive factors, and dietary components. Evidence for each of these mechanisms is reviewed and studies comparing menstrual function between vegetarians and nonvegetarians are described in this article. Although results from several cross-sectional studies suggest that clinical menstrual disturbances may be more common in vegetarians, a prospective study that controlled for many potential confounders found that subclinical disturbances were less common in weight-stable, healthy vegetarian women.

The aim of this study was to investigate the occurrence of livestock-associated methicillin-resistant Staphylococcus aureus (LA-MRSA) human colonization and infections in an area of the Lombardy Region (Italy), the Italian region with the highest density of pig farming. Methods In the period March-April 2010, 879 nasal swabs were taken from subjects at admission to a local hospital serving an area of the Lombardy Region devoted to agriculture and farming. In the period March 2010-February 2011, all MRSA strains from community-acquired infection (CAI) observed in the same hospital, were collected. Molecular characterization of the isolates included SCCmec typing, spa typing and multilocus sequence typing (MLST). Results Out of 879 nasal swabs examined, 9 (1%) yielded MRSA. Five strains were assigned to sequence type (ST)398 (spa t899, 3 isolates; t108 and t2922, 1 isolate each) and were therefore categorized as LA-MRSA. The other 4 isolates were likely of hospital origin. No strains were positive for Panton-Valentine Leukocidin genes. Twenty MRSA isolates were detected from CAI, 17 were from skin and soft-tissue infections and 3 from other infections. An MRSA isolate from otitis externa was t899/ST398 and PVL-negative, hence categorized as LA-MRSA. Four isolates were assigned to t127/ST1. Eight strains were PVL-positive community acquired (CA)-MRSA and belonged to different clones, the most frequent being ST8.

The importance of the metabolic syndrome is not just related to its high prevalence rate but also because it predicts the development of diabetes and cardiovascular disease. Nonalcoholic fatty liver disease is now recognized to be the hepatic component of the metabolic syndrome, which along with its individual components - particularly diabetes and elevated triglycerides, are the major risk factors for the development of nonalcoholic steatohepatitis (NASH); the most severe form of nonalcoholic fatty liver disease. NASH may progress to cirrhosis, hepatocellular carcinoma, and liver failure. It is currently the third most common cause for liver transplantation and is projected to be the leading cause for liver transplantation in 2020. Weight loss (via diet or bariatric surgery) and vitamin E have recently been demonstrated to be effective treatments of NASH. Although these and other agents may prove to be effective treatments for NASH, the most effective therapeutic strategy would be early screening and intervention to prevent the development of insulin resistance and oxidative stress at a societal level. © 2011 The Author.

Usually, these \"\"shares\"\" are all equal; if you own one share you own a percentage of the company equal to that of anyone else who owns one share. The sum total of all shares, theoretically, equals the entire value of the company, and so with N shares in existence, one share is equivalent to 1/Nth the company, and entitles you to 1/Nth of the profits of the company, and more importantly to some, gives you a vote in company matters which carries a weight of 1/Nth of the entire shareholder body. Now, not all of these shares are public. Most companies have the majority (51%+) of shares owned by a small number of \"\"controlling interests\"\". These entities, usually founding owners or their families, may be prohibited by agreement from selling their shares on the open market (other controlling interests have right of first refusal). For \"\"private\"\" companies, ALL the shares are divided this way. For \"\"public\"\" companies, the remainder is available on the open market, and those shares can be bought and sold without involvement by the company. Buyers can't buy more shares than are available on the entire market. Now, when a company wants to make more money, a high share price at the time of the issue is always good, for two reasons. First, the company only makes money on the initial sale of a share of stock; once it's in a third party's hands, any profit from further sale of the stock goes to the seller, not the company. So, it does little good to the company for its share price to soar a month after its issue; the company's already made its money from selling the stock. If the company knew that its shares would be in higher demand in a month, it should have waited, because it could have raised the same amount of money by selling fewer shares. Second, the price of a stock is based on its demand in the market, and a key component of that is scarcity; the fewer shares of a company that are available, the more they'll cost. When a company issues more stock, there's more shares available, so people can get all they want and the demand drops, taking the share price with it. When there's more shares, each share (being a smaller percentage of the company) earns less in dividends as well, which figures into several key metrics for determining whether to buy or sell stock, like earnings per share and price/earnings ratio. Now, you also asked about \"\"dilution\"\". That's pretty straightforward. By adding more shares of stock to the overall pool, you increase that denominator; each share becomes a smaller percentage of the company. The \"\"privately-held\"\" stocks are reduced in the same way. The problem with simply adding stocks to the open market, getting their initial purchase price, is that a larger overall percentage of the company is now on the open market, meaning the \"\"controlling interests\"\" have less control of their company. If at any time the majority of shares are not owned by the controlling interests, then even if they all agree to vote a certain way (for instance, whether or not to merge assets with another company) another entity could buy all the public shares (or convince all existing public shareholders of their point of view) and overrule them. There are various ways to avoid this. The most common is to issue multiple types of stock. Typically, \"\"common\"\" stock carries equal voting rights and equal shares of profits. \"\"Preferred stock\"\" typically trades a higher share of earnings for no voting rights. A company may therefore keep all the \"\"common\"\" stock in private hands and offer only preferred stock on the market. There are other ways to \"\"class\"\" stocks, most of which have a similar tradeoff between earnings percentage and voting percentage (typically by balancing these two you normalize the price of stocks; if one stock had better dividends and more voting weight than another, the other stock would be near-worthless), but companies may create and issue \"\"superstock\"\" to controlling interests to guarantee both profits and control. You'll never see a \"\"superstock\"\" on the open market; where they exist, they are very closely held. But, if a company issues \"\"superstock\"\", the market will see that and the price of their publicly-available \"\"common stock\"\" will depreciate sharply. Another common way to increase market cap without diluting shares is simply to create more shares than you issue publicly; the remainder goes to the current controlling interests. When Facebook solicited outside investment (before it went public), that's basically what happened; the original founders were issued additional shares to maintain controlling interests (though not as significant), balancing the issue of new shares to the investors. The \"\"ideal\"\" form of this is a \"\"stock split\"\"; the company simply multiplies the number of shares it has outstanding by X, and issues X-1 additional shares to each current holder of one share. This effectively divides the price of one share by X, lowering the barrier to purchase a share and thus hopefully driving up demand for the shares overall by making it easier for the average Joe Investor to get their foot in the door. However, issuing shares to controlling interests increases the total number of shares available, decreasing the market value of public shares that much more and reducing the amount of money the company can make from the stock offering.\"", "title": "" }, { "docid": "251713", "text": "A company can issue different kinds of shares.

As such, the preferred structure offers a flexible approach to structuring a preferred offering for an issuer. Companies have many reasons to issue preferred securities. Financial institutions, for example, need to raise capital. Many times they will use the preferred market because of any required regulatory requirements, in addition to cost considerations. Banks and financial institutions are required to maintain a certain level of Tier 1 capital—which includes common equity and perpetual non-cumulative preferreds—as protection against the bank’s liabilities. Issuing more common equity comes at a cost, including the dilution of existing shares, which a company may not want to bear.

Since it is a credit-like security that receives none of the income from operations but merely pays out a potentially unpredictable yet fixed amount of income, it will perform much more like a bond, rising when interest rates fall and vice versa, and since interest rates do not move to the extent of common equity valuations, preferreds' price variances will correspond much more to bonds than common equities. If the company stops paying the preferred dividend or looks to become in financial trouble, the price of the preferred share should be expected to fall. There are more modern preferred however.

Rather, preferred shareholders are normally in line ahead (i.e. in preference to or \"\"preferred\"\") of common shareholders in terms of dividend payment. This is an extremely important distinction, because unlike investments that we generally consider \"\"guaranteed\"\" such as CDs (known as GICs in Canada), a company's board can suspend the dividend at anytime for long periods of time without significant repercussions -- whereas a missed payment to a bank or secured bondholder can often push a company into bankruptcy very quickly. 2) Due to point 1), it is extremely important to know the \"\"convenants\"\" or rules sorrounding both the preferred shares you are buying and the other more senior creditors of that issuing company (i.e. taxes (almost always come first), banks loans, leases, bonds etc.). It is also important to know if a particular preferred share has \"\"cumulative\"\" dividends. You generally only want to buy preferred's that have \"\"cumulative\"\" dividends, since that means that anytime the company misses a payment, they must pay those dividends first before any other dividends at the same or lower priority in the future. 3) Unlike a common stock, your upside on a preferred stock is relatively fixed: you get a fixed share of the company's profit and that's it, whereas a common shareholder gets everything that's left over after interest and preferred dividends are paid. So if the company does really well you will theoretically do much better with common stock over time. For the above reasons, it is generally advisable to think of preferred shares as being more similar to really risky bonds in the same company, rather than similar to common stock.

I ask because, in the US, most people I know associate a \"\"call\"\" option with the instrument that is equivalent to 100 shares. So 100,000 calls would be 10,000,000 shares, which exceeds the number of shares you're saying the company has. I don't know if that means you pulled the numbers out of thin air, or whether it means you're thinking of a different type of option? Perhaps you meant incentive stock options meant to be given to employees? Each one of those is equivalent to a single share. They just aren't called \"\"call options\"\". In the rest of my answer, I'm going to assume you meant stock options. I assume the fact that these options exist will slow any price increases on the underlying shares due to potential dilution? I don't think the company can just create stock options without creating the underlying shares in the first place. Said another way, a more likely scenario is that company creates 200,000 shares and agrees to float 50% of them while reserving the other 50% as the pool for incentive employee stock. They then choose to give the employees options on the stock in the incentive pool, rather than outright grants of the stock, for various reasons. (One of which is being nice to the employees in regards to taxes since there is no US tax due at grant time if the strike price is the current price of the underlying stock.) An alternative scenario when the company shares are liquidly traded is that the company simply plans to buy back shares from the market in order to give employees their shares when options are exercised. In this case, the company needs the cash on hand, or cash flow to take money from, to buy those shares at current prices. Anyway, in either case, there is no dilution happening WHEN the options get exercised. Any dilution happened before or at the time the options were created. Meaning, the total number of shares in the company was already pre-set at an earlier time. As a result, the fact that the options exist in themselves will not slow price changes on the stock. However, price changes will be impacted by the total float of shares in the company, or the impact to cash flow if the company has to buy shares to redeem its option commitments. This is almost the same thing you're asking about, but it is technically different as to timing. If this is the case, can this be factored into any option pricing models like black-scholes?

Had he kept his head in the game he could probably have saved himself. But he didn't. If your average startup started issuing lots of stock and devaluing existing shares significantly then I would expect it would be harder to find investors willing to watch as their investment dwindled. But if you are issuing a limited amount stock to get leverage to grow bigger then it is worth it. In the .com bubble there were quite a few companies that just issued stock to buy other companies. Eventually most of these companies got delisted because they diluted them selves to much when they were overvalued. Any company not just a startup can dilute its shares. Many if not most major companies issue stock to raise capital. This capital is then generally used to build the business further and increase the value of all shares. Most of the time this dilution is very minor (<.1%) and has little if any impact on the stock. There are rules that have to be followed as listed companies are regulated by the SEC. There are less regulations with private corporations. It looks like the dilution was combined with the buyout of the Florida company which probably contributed to the legality of the dilution. With options they are generally issued at a set price. This may be higher or lower than the reported sell price of the stock when the option is issued.

So, we have an ice cream shop. We started it as partners, and now you and I each own 50% of the company. It's doing so well that we decide to take it public. That means that we will be giving up some of our ownership in return for a chance to own a smaller portion of a bigger thing. With the money that we raise from selling stocks, we're going to open up two more stores. So, without getting into too much of the nitty gritty accounting that would turn this into a valuation question, let's say we are going to put 30% of the company up for sale with these stocks, leaving you and me with 35% each. We file with the SEC saying we're splitting up the company ownership with 100,000 shares, and so you and I each have 35,000 shares and we sell 30,000 to investors. Then, and this depends on the state in the US where you're registering your publicly traded corporation, those shares must be assigned a par value that a shareholder can redeem the shares at. Many corporations will use $1 or 10 cents or something nominal. And we go and find investors who will actually pay us $5 per share for our ice cream shop business. We receive $150,000 in new capital. But when we record that in our accounting, $5 in total capital per share was contributed by investors to the business and is recorded as shareholder's equity. $1 per share (totalling $30,000) goes towards actual shares outstanding, and $4 per share (totalling $120,000) goes towards capital surplus. These amounts will not change unless we issue new stocks. The share prices on the open market can fluctuate, but we rarely would adjust these. Edit: I couldn't see the table before. DumbCoder has already pointed out the equation Capital Surplus = [(Stock Par Value) + (Premium Per Share)] * (Number of Shares) Based on my example, it's easy to deduce what happened in the case you've given in the table. In 2009 your company XYZ had outstanding Common Stock issued for $4,652. That's probably (a) in thousands, and (b) at a par value of $1 per share. On those assumptions we can say that the company has 4,652,000 shares outstanding for Year End 2009. Then, if we guess that's the outstanding shares, we can also calculate the implicit average premium per share: 90,946,000 ÷ 4,652,000 == $19.52. Note that this is the average premium per share, because we don't know when the different stocks were issued at, and it may be that the premiums that investors paid were different. Frankly, we don't care. So clearly since \"\"Common Stock\"\" in 2010 is up to $9,303 it means that the company released more stock. Someone else can chime in on whether that means it was specifically a stock split or some other mechanism... it doesn't matter. For understanding this you just need to know that the company put more stock into the marketplace... 9,303 - 4,652 == 4,651(,000) more shares to be exact. With the mechanics of rounding to the thousands, I would guess this was a stock split. Now. What you can also see is that the Capital Surplus also increased. 232,801 - 90,946 == 141,855. The 4,651,000 shares were issued into the market at an average premium of 141,855 ÷ 4,651 == $30.50. So investors probably paid (or were given by the company) an average of $31.50 at this split. Then, in 2011 the company had another small adjustment to its shares outstanding. (The Common Stock went up). And there was a corresponding increase in its Capital Surplus.

Small growth companies need new financing frequently to fund their growth strategies. Revenue went up, great... why? Did you open another store? Did you open another sales office? Did the revenue increase this quarter based on substantially the same operation that existed last quarter or have you increased the capacity of your operation? If you increased the capacity of your operation what was the cost of the increase and did revenue increase as expected? Can you expect revenue to continue to grow at this rate or was it a one time windfall from an unusual order? Sure, there are spectacular gains to be had in penny stocks. XYZ Pharma Research (or whatever) goes from $0.05 to $0.60 and you've turned your $1,000 in to $12,000. This is a really unlikely event... Buying penny stocks is akin to buying lottery tickets. Unless you are a high ranking employee at the company capable of making decisions, or one of the investors buying the preferred shares mentioned in point 3, or are one of the insiders of a pump and dump scam on the stock, penny common stocks are not a place to invest. One could argue that even a company insider should probably avoid buying common stock. Just to illustrate the points above, you mention: Doing some really heavy research into this stock has made me question the whole penny stock market. Based on your research what is the enterprise value of the company? What were the gross proceeds of the last financing round, how many shares were issued and were there any warrants attached? What do you perceive to be heavy research? What background do you have in finance/accounting to give weight to your ability to perform such research? Crawl. Walk. Then run.

Say, I am a Walton (of Walmart fame) and when I went public, I sold 80% of the (1000 share total) company. But, in creating the share structure, 20% of shares were assigned 10 votes each. 800 shares now trade with 800 votes, 200 shares have 10 votes each or 2000 votes. So, there are still the 1000 shares but 2800 votes. The 20% of shares now have 2000/2800 or 71% of the total votes. So, my shares are just less than half ownership, but over 78% of votes.

Note that the terms 'common shares' and 'preferred shares' are generally understood terms, but are not as precise as you might believe. There are dozens/hundreds of different characteristics that could be written into share classes in the company's articles of incorporation [as long as those characteristics are legal in corporate law in the company's jurisdiction]. So in answering your question there's a bit of an assumption that things are working 'as usual'. Note that private companies often have odd quirks to their share classes, things like weird small classes of shares that have most of the voting rights, or shares with 'shotgun buyback clauses'. As long as they are legal clauses, they can be used to help control how the business is run between various shareholders with competing interests. Things like parents anticipating future family infighting and trying to prevent familial struggle. You are unlikely to see such weird quirks in public companies, where the company will have additional regulatory requirements and where the public won't want any shock at unexpected share clauses. In your case, you suggested having a non-cumulative preferred share [with no voting rights, but that doesn't impact dividend payment]: There are two salient points left related to payout that the articles of incorporation will need to define for the share classes: (1) What is the redemption value for the shares? [This is usually equal to the cost of subscribing for the shares in the first place; it represents how much the business will need to pay the shareholder in the event of redemption / recall] (2) What is the stated dividend amount? This is usually defined at a rate that's at or a little above a reasonable interest rate at the time the shares are created, but defined as $ / share. For example, the shares could have $1 / share dividend payment, where the shares originally cost $50 each to subscribe [this would reflect a rate of payment of about 2%]. Typically by corporate law, dividends must be paid to preferred shares, to the extent required based on the characteristics of the share class [some preferred shares may not have any required dividends at all], before any dividends can be paid to common shares. So if $10k in dividends is to be paid, and total preferred shares require $15k of non-cumulative dividends each year, then $0 will be paid to the common shares. The following year, $15k of dividends will once again need to be paid to the preferred shares, before any can be paid to the common shares.", "title": "" }, { "docid": "12899", "text": "Full disclosure: I’m an intern for EquityZen, so I’m familiar with this space but can speak with the most accuracy about EquityZen. Observations about other players in the space are my own. The employee liquidity landscape is evolving. EquityZen and Equidate help shareholders (employees, ex-employees, etc.) in private companies get liquidity for shares they already own. ESOFund and 137 Ventures help with option financing, and provide loans (and exotic structures on loans) to cover costs of exercising options and any associated tax hit. EquityZen is a private company marketplace that led the second wave of VC-backed secondary markets starting early 2013. The mission is to help achieve liquidity for employees and other private company shareholder, but in a company-approved way. EquityZen transacts with share transfers and also a proprietary derivative structure which transfers economics of a company's shares without changing voting and information rights. This structure typically makes the transfer process cheaper and faster as less paperwork is involved. Accredited investors find the process appealing because they get access to companies they usually cannot with small check sizes. To address the questions in Dzt's post: 1). EquityZen doesn't take a 'loan shark' approach meaning they don't front shareholders money so that they can purchase their stock. With EquityZen, you’re either selling your shares or selling all the economic risk—upside and downside—in exchange for today’s value. 2). EquityZen only allows company approved deals on the platform. As a result, companies are more friendly towards the process and they tend to allow these deals to take place. Non-company approved deals pose risks for buyers and sellers and are ultimately unsustainable. As a buyer, without company blessing, you’re taking on significant counterparty risk from the seller (will they make good on their promise to deliver shares in the future?) or the risk that the transfer is impermissible under relevant restrictions and your purchase is invalid. As a seller, you’re running the risk of violating your equity agreements, which can have severe penalties, like forfeiture of your stock. Your shares are also much less marketable when you’re looking to transact without the company’s knowledge or approval. 3). Terms don't change depending an a shareholder's situation. EquityZen is a professional company and values all of the shareholders that use the platform. It’s a marketplace so the market sets the price. In other situations, you may be at the mercy of just one large buyer. This can happen when you’re facing a big tax bill on exercise but don’t have the cash (because you have the stock). 4). EquityZen doesn't offer loans so this is a non issue. 5). Not EquityZen! EquityZen creates a clean break from the economics. It’s not uncommon for the loan structures to use an interest component as well as some other complications, like upside participation and and also a liquidation preference.

An IPO is the way most companies get a public listing on the stock market. However, companies often go to market again and again to issue/sell more shares, after their IPO. These secondary offerings don't make as many headlines as an IPO, but they are typical-enough occurrences in markets. When a company goes back to the market to raise additional funds (perhaps to fund expansion), the value of the company's existing shares that are being traded is a good indicator of what they may expect to get for a secondary offering of shares. A company about to raise money desires a higher share price, because that will permit them to issue less shares for the amount of money they need. If the share price drops, they would need to issue more shares for the same amount of money – and dilute existing owners' share of the overall equity further. Also, consider corporate acquisitions: When one company wants to buy another, instead of the transaction being entirely in cash (maybe they don't have that much in the bank!), there's often an equity component, which involves swapping shares of the company being acquired for new shares in the acquiring company or merged company.

So if you have a share that is rock solid at $100, you don't make money. If you have a share where the company owner took some ridiculous risk, and the shares could go to $200 or the company could go bankrupt, then you have a 50% chance to make $100 and a 50% chance to not lose anything.

I'm assuming you're buying the shares on B's stock exchange through an ADR, GDR, or similar instrument. The risk occurs as a result of the process through which the ADR is created. In its simplest form, the process works like this: I'll illustrate this with an example. I've separated the conversion rate into the exchange rate and a generic \"\"ADR conversion rate\"\" which includes all other factors the bank takes into account when deciding how many ADR shares to sell. The fact that the units line up is a nice check to make sure the calculation is logically correct. My example starts with these assumptions: I made up the generic ADR conversion rate; it will remain constant throughout this example. This is the simplified version of the calculation of the ADR share price from the European share price: Let's assume that the euro appreciates against the US dollar, and is now worth 1.4 USD (this is a major appreciation, but it makes a good example): The currency appreciation alone raised the share price of the ADR, even though the price of the share on the European exchange was unchanged. Now let's look at what happens if the euro appreciates further to 1.5 USD/EUR, but the company's share price on the European exchange falls: Even though the euro appreciated, the decline in the share price on the European exchange offset the currency risk in this case, leaving the ADR's share price on the US exchange unchanged. Finally, what happens if the euro experiences a major depreciation and the company's share price decreases significantly in the European market? This is a realistic situation that has occurred several times during the European sovereign debt crisis. Assuming this occurred immediately after the first example, European shareholders in the company experienced a (43.50 - 50) / 50 = -13% return, but American holders of the ADR experienced a (15.95 - 21.5093) / 21.5093 = -25.9% return. The currency shock was the primary cause of this magnified loss. Another point to keep in mind is that the foreign company itself may be exposed to currency risk if it conducts a lot of business in market with different currencies. Ideally the company has hedged against this, but if you invest in a foreign company through an ADR (or a GDR or another similar instrument), you may take on whatever risk the company hasn't hedged in addition to the currency risk that's present in the ADR/GDR conversion process. Here are a few articles that discuss currency risk specifically in the context of ADR's: (1), (2). Nestle, a Swiss company that is traded on US exchanges through an ADR, even addresses this issue in their FAQ for investors.

However, various stock management policies on the part of the shareholder, brokerage firm or the issuing company can result in you owning fractional shares. Perhaps the most common is a retirement account or other forward-planning account. In such situations, it's the dollar amount that counts; when you deposit money you expect the money to be invested in your chosen mix of mutual funds and other instruments. If the whole-shares rule were absolute, and you wanted to own, for instance, Berkshire Hathaway stock, and you were contributing a few hundred a month, it could take you your entire career of your contributions sitting in a money-market account (essentially earning nothing) before you could buy even one share. You are virtually guaranteed in such situations to end up owning fractions of shares in an investment account. In these situations, it's usually the fund manager's firm that actually holds title to the full share (part of a pool they maintain for exactly this situation), and your fractional ownership percentage is handled purely with accounting; they give you your percentage of the dividends when they're paid out, and marginal additional investments increase your actual holdings of the share until you own the whole thing.

Companies often aren't looking to halve their stock price by offering a two-for-one split; they may think a smaller figure like 50% or even smaller is preferable, to fine tune their stock price (and thus P/E ratio and EPS figures) similar to industry competitors or to companies with similar market capitalization. In such situations they can offer a split that's X-for-Y with X>Y, like a 3-for-2, 5-for-3 or similar.

After all company liabilities have been paid off [including bank debt, wages owing, taxes outstanding, etc etc.], the remaining cash value in a company is distributed to the shareholders. In general, there are 2 types of shares: Preferred shares, and Common shares. Preferred shares generally have 3 characteristics: (1) they get a stated dividend rate every year, sometimes regardless of company performance; (2) they get paid out first on liquidation; and (3) they can only receive their stated value on liquidation - that is, $1M of preferred shares will be redeemed for at most $1M on liquidation, assuming the corporation has at least that much cash left. Common Shares generally have 4 characteristics: (1) their dividends are not guaranteed (or may be based on a calculation relative to company performance), (2) they can vote for members of the Board of Directors who ultimately hire the CEO and make similar high level business decisions; (3) they get paid last on liquidation; and (4) they get all value remaining in the company once everyone else has been paid.

Lending to the bank
[ { "docid": "458485", "text": "\"This will happen automatically when you open an interest-bearing account with a bank. You didn't think that banks just kept all that cash in a vault somewhere, did you? That's not the way modern banking works. Today (and for a long, long time) banks will keep only a small fraction of their deposits on hand (called the \"\"reserve\"\") to fund daily withdrawals and other operations. The rest they routinely lend out to other customers, which is how they pay for their operations (someone has to pay all those tellers, branch managers, loan officers) and pay interest on your deposits, as well as a profit for their owners (it's not a charity service). The fees charged for loan origination, as well as the difference between the loan interest rate and the deposit rate, make up the profit. Banks rarely hold their own loans. Instead, they will sell the loans in portfolios to investors, sometimes retaining servicing rights (they continue to collect the payments and pass them on) and sometimes not (the payments are now due to someone else). This allows them to make more loans. Banks may sometimes not have enough capital on hand. In this case, they can make inter-bank loans to meet their short-term needs. In some cases, they'll take those loans from a government central bank. In the US, this is \"\"The Fed\"\", or the Federal Reserve Bank. In the US, back around the late 1920's, and again in the 1980's some banks experienced a \"\"run\"\", or a situation where people lost confidence in the bank and wanted to withdraw their money. This caused the bank to have insufficient funds to support the withdrawals, so not everyone got their money. People panicked, and others wanted to take their money out, which caused the situation to snowball. This is how many banks failed. (In the '80s, it was savings-and-loans that failed - still a kind of \"\"bank\"\".) Today, we have the FDIC (Federal Deposit Insurance Corporation) to protect depositors. In the crashes in the early 2000's, many banks closed up one night and opened the next in a conservatorship, and then were literally doing business as a new bank without depositors (necessarily) even knowing.

The bank is also unable to diversify away all possible risk, but tries to do the best job it can. If a bank is seen to take bigger risks and therefore be in greater risk of failing (having a run on deposits) it must have a requisitely higher interest rates on deposits compared to a lower risk bank. \"\"Savers\"\" therefore \"\"shop around\"\" for the best interest rate for a given level of risk which sets the viable interest rate for that bank; any higher and the bank would not make a profit on the money that it lends out and so would not be viable as a business, any lower and savers would not deposit their money as the risk would be too high for the reward. Hence competition (or lack of it) will set the rate as a trade off between risk and return. Note that governments are also customers of the banking industry when they are issuing fixed income securities (bonds) and a good deal of the lending done by any bank is to various governments so the price that they borrow money at is a key determinant of what interest rate the bank can afford to give and are part of the competitive banking industry whether they want to be or not.

That these banks lend to each other on an incredibly regular basis (look into the overnight or repo money market if you want to see exactly how much, the rates that these banks pay to and receive from each other are governed by interbank lending rates called Libor and Euribor and are even more complicated than this answer) simply compounds this effect because it makes all of the banks reliant on each other and therefore they help each other to stay liquid (to some extent). Note that I haven't mentioned currency at all so far but this market in every country applies over a number of currencies. The way that this occurs is due to arbitrage; if I can put foreign money into a bank in a country at a rate that is higher than the rate in its native country after exchange costs and exchange rate risk I will convert all of my money to that currency and take the higher interest rate. For an ordinary individual's savings that is not really possible but remember that the large multinational banks can do exactly the same thing with billions of dollars of deposits and effectively get free money. This means that either the bank's interest rate will fall to a risk adjusted level or the exchange rate will move. Either of those moves will remove the potential for making money for nothing. In this case, therefore it is both the exchange rate risk (and costs) as well as the loan market in that country that set the interest rate in foreign currencies. Demand for loans in the foreign currency is not a major mover for the same reason. Companies importing from foreign entities need cash in foreign currencies to pay their bills and so will borrow money in other currencies to fulfil these operations which could come from deposits in the foreign currency if they were available at a lower interest rate than a loan in local currency plus the costs of exchange but the banks will be unwilling to loan to them for less than the highest return that they can get so will push up interest rates to their risk level in the same way that they did in the market before currencies were taken into account. Freedom of movement of foreign currencies, however, does move interest rates in foreign currencies as the banks want to be able to lend as much of currencies that are not freely deliverable as they can so will pay a premium for these currencies. Other political moves such as the government wanting to borrow large amounts of foreign currency etc. will also move the interest rate given for foreign currencies not just because loaning to the government is less risky but also because they sometimes pay a premium (in interest) for being able to borrow foreign currency which may balance this out. Speculation that a country may change its base interest rate will move short term rates, and can move long term rates if it is seen to be a part of a country's economic strategy. The theory behind this is deep and involved but the tl;dr answer would be the standard \"\"invisible hand\"\" response when anything market or arbitrage related is involved. references: I work in credit risk and got a colleague who is also a credit risk consultant and economist to look over it.

Fractional reserve lending (banking) is simply that when someone deposits money into a bank, the bank is allowed to loan that money out, so long as they keep a reserve. If the reserve rate is 10% (it's much lower in reality), and someone deposits $100 into the bank, the bank can then loan out $90. That is fractional reserve lending at its most basics. Now fractional reserve lending does have a multiplier effect. And this effect is exactly how I described it. Let's go back to the example. Person A deposits the $100, the bank then loans $90 to person B, person B spends it with person C, person C takes the money and deposits back to the bank. Now the bank has the $100 cash back, $90 in loans and the $190 in deposits, so they need to hold onto $19 as a reserve and can loan out $81. Assuming the money cycles with 100% efficiency, the bank can continue loaning out the same money until they are left with $1000 in deposits, $900 in loans, and the original $100 is the reserve.

The interest and fees from those loans go to pay the salaries of those working at the banks with leftover profit to pay dividends (interest on your bank accounts). The only reason that the Federal Reserve allows overnight lending is so that banks don't immediately become insolvent if they have larger than usual withdrawals by their depositors. The Federal Reserve keeps an eye on the balance sheets of the banks that are doing the borrowing, and if they didn't have assets in the form of deposits, they would force the banks to sell the loans that were made from those deposits. What does this have to do with personal finance? I think this question is only marginally on-topic here. This amount of money in circulation is affected specifically by the fraction of the money that can be used for making other loans.

But inside the investment bank’s New York headquarters, it feels like an insult. Goldman is not suffering a financial crisis, as it did in 2008 when it officially converted to being a bank holding company amid panic that the whole of Wall Street could collapse. It faces something deeper: an identity crisis. It used to be the role model for many rival banks — envied even while resented for its single-minded focus on investment banking and trading. But as Tuesday’s disclosure of a 26 per cent fall in its bond trading revenues confirmed, banking has changed. Instead of lenders such as JPMorgan Chase wanting to become as glamorous as Goldman, it needs to be more like them. This is a telling moment, albeit less dramatic than 2008. Investment banking enjoyed a lucrative two decades, spurred by globalisation and financial liberalisation. Goldman’s revenues rose briskly from its initial public offering in 1999 to 2007, and boomed in 2009. It could do no wrong financially, although it turned out to have done wrong to some of its customers. But guess what? Regulation works. Governments and central bank supervisors set out to make complex trading in bonds and derivatives, the securities business in which Goldman specialised, more expensive and less profitable. The rules now favour deposit taking and lending instead of wizardry. No one really planned the second aspect of the bank’s difficulty. The huge dose of monetary easing since the crisis has damped volatility and made markets more predictable. Hedge funds, themselves under pressure, no longer need to reward Goldman and others for taking on financial risk. Goldman’s bond and commodities trading division — from which emerged a cadre of leaders including Lloyd Blankfein, its chairman and chief executive — tells its own story. It used to occupy two floors of the New York office but has shrunk to one as Wall Street’s total bond trading revenues have halved since 2009. More prices are calculated by computers than humans. When you rely heavily on one engine and that engine sputters, you are in trouble. The bank’s financial advisory and capital raising division is performing well and it has an investment management arm. But it lacks a consumer powerhouse like Morgan Stanley’s wealth management operation, or the lending and credit card activities that drive banks such as JPMorgan. The humbling truth for Goldman is that US retail banking has become not only more reliable than investment banking, but more profitable. JPMorgan’s balance sheet is three times the size of Goldman’s and its retail banking arm made a 19 per cent return on equity in the third quarter, compared with Goldman’s 11 per cent. The best historical comparison for Goldman’s predicament is, ironically, the JPMorgan of the 1990s. JPMorgan was a blue-chip corporate bank but found that this business was no longer profitable enough as lending margins fell. It launched an effort to return to investment banking, having been separated from Morgan Stanley in 1935 by the Glass-Steagall Act. JPMorgan had a good stab at it, compensating for the fact that Goldman and others dominated Wall Street’s “bulge bracket” by pioneering credit derivatives (which later turned out badly). But it could not make enough progress alone and settled for being bought by Chase Manhattan in 2000. “Both [banks] have struggled to keep pace with the rapid growth of the leading investment banks, which are in businesses that have been far more lucrative than the lending business at the core of commercial banking,” the New York Times noted in its account of the merger. Seventeen years and one financial crisis later, JPMorgan has reversed this order of profitability. So Goldman is now trying to do the opposite of the old JPMorgan by adding banking to investment banking. JPMorgan’s former dilemma has not gone away — lending to blue-chip companies is not much of a moneymaker. A more tempting target is the high margins that banks make on credit cards. Hence Marcus, Goldman’s online lender (named after its founder Marcus Goldman), which offers loans to prime US consumers as an alternative to credit card debt. Marcus, which will launch next year in the UK, accounts for $12bn of the $28bn in new lending and financing planned by Goldman in the next three years as it diversifies. But it is no simpler for Goldman to break into Main Street than it was for the old JPMorgan to break back into Wall Street: $12bn on a balance sheet of $930bn is an interesting financial experiment, not a revolution. It would need to inflict on consumer banking with technology what Amazon did to the retail industry to rival fully JPMorgan and Bank of America. “We’re a bank and we’re committed to being a bank,” says one partner firmly.

Carcinogens in Roasted Coffee?
[ { "docid": "MED-4472", "text": "N-Nitroso compounds were known almost 40 years ago to be present in food treated with sodium nitrite, which made fish meal hepatotoxic to animals through formation of nitrosodimethylamine (NDMA). Since that time, N-nitroso compounds have been shown in animal experiments to be the most broadly acting and the most potent group of carcinogens. The key role of nitrite and nitrogen oxides in forming N-nitroso compounds by interaction with secondary and tertiary amino compounds has led to the examination worldwide of foods for the presence of N-nitroso compounds, which have been found almost exclusively in those foods containing nitrite or which have become exposed to nitrogen oxides. Among these are cured meats, especially bacon-and especially when cooked; concentrations of 100 micrograms kg(-1) have been found or, more usually, near 10 micrograms kg(-1). This would correspond to consumption of 1 microgram of NDMA in a 100-g portion. Much higher concentrations of NDMA (but lower ones of other nitrosamines) have been found in Japanese smoked and cured fish (more than 100 micrograms kg(-1)). Beer is one source of NDMA, in which as much as 70 micrograms l(-1) has been reported in some types of German beer, although usual levels are much lower (10 or 5 micrograms l(-1)); this could mean a considerable intake for a heavy beer drinker of several liters per day. Levels of nitrosamines have been declining during the past three decades, concurrent with a lowering of the nitrite used in food and greater control of exposure of malt to nitrogen oxides in beer making. There have been declines of N-nitroso compound concentrations in many foods during the past two decades. The small amounts of nitrosamines in food are nonetheless significant because of the possibility-even likelihood-that humans are more sensitive to these carcinogens than are laboratory rodents. Although it is probable that alkylnitrosamides (which induce brain tumors in rodents) are present in cured meats and other potentially nitrosated products in spite of much searching, there has been only limited indirect evidence of their presence.

Nitrites, together with ubiquitous amines, can lead to an in-vivo synthesis of carcinogenic nitrosamines. The average daily intake of nitrates depends upon the amount of vegetables consumed and on the nitrate concentration in drinking water. Agricultural practices play an important part in the concentration of nitrate in both water and vegetables. If nitrate is taken up by the plant and not metabolised to amino acids, proteins or nucleic acids, it is stored in cell vacuoles as a reserve. However, with an over-supply of nitrate relative to possible photosynthesis, this stored nitrate is still present at harvest and leads to high concentrations in plant tissue. The nitrate content in plants also depends upon other factors, such as plant variety (cultivar), kind and amount of fertiliser, time of harvest and environmental factors such as light intensity, temperature, etc. It is suggested that we should try to meet the recommendations of toxicologists who believe a dramatic reduction nitrate intake for humans is necessary. It has been demonstrated that modern biological-organic farming methods clearly lead both to lower leaching of nitrates and to lower nitrate content in vegetables.

Lifetime intakes of grilled or barbecued and smoked meats were derived from the interviewer-administered questionnaire data. Dietary intakes of PAH and HCA were derived from the self-administered modified Block food frequency questionnaire of intake 1 year before reference date. Unconditional logistic regression was used to estimate adjusted odds ratios (ORs) and 95% confidence intervals (CIs). RESULTS: Modest increased risk was observed among postmenopausal, but not premenopausal, women consuming the most grilled or barbecued and smoked meats over the life course (OR = 1.47; CI = 1.12-1.92 for highest vs. lowest tertile of intake). Postmenopausal women with low fruit and vegetable intake, but high lifetime intake of grilled or barbecued and smoked meats, had a higher OR of 1.74 (CI = 1.20-2.50).

The received particle dose indoors may exceed noticeably the dose from ambient air under routine in-house activities like cooking. In the present work, the internal dose by inhalation of ultrafine and fine particles is assessed, using an appropriate mechanistic model of lung deposition, accommodating aerosol, and inhalation dynamics. The analysis is based on size distribution measurements (10-350 nm) of indoor and outdoor aerosol number concentrations in a typical residence in Athens, Greece. Four different cases are examined, namely, a cooking event, a no activity period indoors and the equivalent time periods outdoors. When the cooking event (frying of bacon-eggs with a gas fire) occurred, the amount of deposited particles deep into the lung of an individual indoors exceeded by up to 10 times the amount received by an individual at the same time period outdoors. The fine particle deposition depends on the level of physical exertion and the hygroscopic properties of the inhaled aerosol. The dose is not found linearly dependant on the indoor/outdoor concentrations during the cooking event, whereas it is during the no activity period. PRACTICAL IMPLICATIONS: The necessity for determining the dose in specific regions of the human lung, as well as the non-linear relationship between aerosol concentration and internal dose makes the application of dosimetry models important. Lung dose of fine and ultrafine particles, during a cooking event, is compared with the dose at no indoor activity and the dose received under outdoor exposure conditions. The dose is expressed in terms of number or surface of deposited particles. This permits to address the dosimetry of very small particles, which are released by many indoor sources but represent a slight fraction of the particulate matter mass. The enhancement of the internal dose resulting from fine and ultrafine particles generated during the cooking event vs. the dose when no indoor source is active is assessed.

A meta-analysis was performed examining the possible association of maternal intake of cured meat (an important source of dietary NOCs) during pregnancy and the risk of pediatric brain tumors. METHODS: Data from epidemiological studies were pooled using a general variance-based meta-analytic method employing confidence intervals described by Greenland in 1986. The outcome of interest was a summary relative risk (RR) reflecting the risk of childhood brain tumor (CBT) development associated with maternal intake of cured meats during pregnancy. Sensitivity analyses were performed when necessary to explain any observed statistical heterogeneity. RESULTS: Seven observational studies were found that met the protocol-specified inclusion criteria. Analysis for heterogeneity demonstrated a lack of statistical heterogeneity (p = 0.59), indicating that the data could be statistically combined. Pooling data from the 6 reports containing data on maternal cured meat intake of all types yielded an RR of 1.68 (1.30- 2.17), being a statistically significant result. Analyzing CBT risk by type of cured meat ingested showed that hot dog consumption increased CBT risk by 33% (1.08-1.66), with a similar increase shown by frequent ingestion of sausage, i.e. 44%. CONCLUSION: The data provide support for the suspected causal association between ingestion of NOCs from cured meats during pregnancy and subsequent CBT in offspring.

A total of 31 phenolic compounds corresponding to flavan-3-ols (33% to 56% of the total of phenolic compounds identified), flavonol glycosides (9% to 36%), hydroxybenzoic acids and aldehydes (6% to 26%), flavonol aglycones (1.7% to 18%), flavanone glycosides (3% to 7.7%), flavanone aglycones (0.69% to 5.4%), hydroxycinnamic acids (0.65% to 2.6%), and dihydroflavonol aglycones (0% to 2.8%) were determined in the skins from 3 different varieties of almonds. The total contents of phenolic compounds identified were significantly (P < 0.05) higher (around 2-fold) in the roasted samples than in the blanched almonds (freeze-dried). Industrial drying (oven drying) of the blanched almond skins produced an increase (< 2-fold) in the contents of phenolic compounds, although the results were only statistically significant (P < 0.05) for some samples. The antioxidant activity (ORAC values) was higher for the roasted samples (0.803 to 1.08 mmol Trolox/g), followed by the samples subjected to blanching + drying (0.398 to 0.575 mmol Trolox/g) and then the blanched (freeze-dried) samples (0.331 to 0.451 mmol Trolox/g).

Their consumption is associated with reduced CVD risk and they pose little threat to positive energy balance. However, questions have arisen as to whether product form (e.g. whole nut v. butter) and processing properties (e.g. roasting and adding flavours) may compromise their positive health effects. The present study investigated the effects of peanut form and processing on two CVD risk factors: fasting plasma lipids and body weight. One hundred and eighteen adults (forty-seven males and seventy-one females; age 29.2 (sd 8.4) years; BMI 30.0 (sd 4.5) kg/m2) from Brazil, Ghana and the United States were randomised to consume 56 g of raw unsalted (n 23), roasted unsalted (n 24), roasted salted (n 23) or honey roasted (n 24) peanuts, or peanut butter (n 24) daily for 4 weeks. Peanut form and processing did not differentially affect body weight or fasting plasma lipid responses in the total sample. However, HDL-cholesterol increased significantly at the group level, and total cholesterol, LDL-cholesterol and TAG concentrations decreased significantly in individuals classified as having elevated fasting plasma lipids compared with those with normal fasting plasma lipids. These observations suggest that the processing attributes assessed in this trial do not compromise the lipid-lowering effects of peanuts, and do not negatively impact body weight.

Restriction of dietary phosphorus is necessary to control for phosphate balance during both conservative therapy and dialysis treatment. The extra amount of phosphorus which is consumed as a result of phosphate-containing food additives is a real challenge for patients with renal disease and for dieticians because it represents a \"hidden\" phosphate load. The objective of this study was to measure phosphorus content in foods, common protein sources in particular, and comprised both those which included a listing of phosphate additives and those which did not. METHODS: Determinations of dry matter, nitrogen, total and soluble phosphate ions were carried out in 60 samples of foods, namely cooked ham, roast breast turkey, and roast breast chicken, of which, 30 were with declared phosphate additives and the other 30 similar items were without additives. RESULTS: Total phosphorus (290 ± 40 mg/100 g vs. 185 ± 23 mg/100 g, P < .001) and soluble phosphorus (164 ± 25 mg/100 g vs. 100 ± 19 mg/100 g, P < .001) content were higher in products containing additives than in foods without additives. No difference was detected between the 2 groups regarding dry matter (27.2 ± 2.0 g/100 g vs. 26.7 ± 1.9 g/100 g) or total nitrogen (3.15 ± 0.40 g/100 g vs. 3.19 ± 0.40 g/100 g). Consequently, phosphorus intake per gram of protein was much greater in the foods containing phosphorus additives (15.0 ± 3.1 mg/g vs. 9.3 ± 0.7 mg/g, P < .001). CONCLUSIONS: Our results show that those foods which contain phosphate additives have a phosphorus content nearly 70% higher than the samples which did not contain additives. This creates a special concern because this extra amount of phosphorus is almost completely absorbed by the intestinal tract. These hidden phosphates worsen phosphate balance control and increase the need for phosphate binders and related costs. Information and educational programs are essential to make patients with renal disease aware of the existence of foods with phosphate additives. Moreover, these facts highlight the need for national and international authorities to devote more attention to food labels which should clearly report the amount of natural or added phosphorus.

We calculated the summary relative risk (RR) for any, low, and high consumption of coffee vs no consumption. The cut-off point for low vs high consumption was set to 3 cups per day in 9 studies and 1 cup per day in 5 studies. RESULTS: The summary RR for any coffee consumption vs no consumption was 0.60 from 16 studies, comprising a total of 3153 HCC cases (95% confidence interval [CI], 0.50-0.71); the RRs were 0.56 from 8 case-control studies (95% CI, 0.42-0.75) and 0.64 from 8 cohort studies (95% CI, 0.52-0.78).

Multivariate relative risks (RRs) and 95% confidence intervals (CIs) were estimated by Cox proportional hazard models. Results: Coffee intake was inversely associated with incident liver cancer (RR per cup per day=0.82, 95% CI: 0.73–0.93; P-trend across categories=0.0007) and mortality from chronic liver disease (RR=0.55, 95% CI: 0.48–0.63; P-trend<0.0001). Inverse associations persisted in those without diabetes, HBV- and HCV-negative cases, and in analyses stratified by age, body mass index, alcohol and smoking dose. We observed similar associations for those drinking boiled or filtered coffee.

Controversies regarding its benefits and risks still exist as reliable evidence is becoming available supporting its health promoting potential; however, some researchers have argued about the association of coffee consumption with cardiovascular complications and cancer insurgence. The health-promoting properties of coffee are often attributed to its rich phytochemistry, including caffeine, chlorogenic acid, caffeic acid, hydroxyhydroquinone (HHQ), etc. Many research investigations, epidemiological studies, and meta-analyses regarding coffee consumption revealed its inverse correlation with that of diabetes mellitus, various cancer lines, Parkinsonism, and Alzheimer's disease. Moreover, it ameliorates oxidative stress because of its ability to induce mRNA and protein expression, and mediates Nrf2-ARE pathway stimulation. Furthermore, caffeine and its metabolites help in proper cognitive functionality. Coffee lipid fraction containing cafestol and kahweol act as a safeguard against some malignant cells by modulating the detoxifying enzymes. On the other hand, their higher levels raise serum cholesterol, posing a possible threat to coronary health, for example, myocardial and cerebral infarction, insomnia, and cardiovascular complications. Caffeine also affects adenosine receptors and its withdrawal is accompanied with muscle fatigue and allied problems in those addicted to coffee.

This prospective trial was aimed at assessing the mechanisms underlying coffee-related protective effects. METHODS: Forty patients with chronic hepatitis C were randomized into two groups: the first consumed 4 cups of coffee/day for 30 days, while the second remained coffee \"abstinent\". At day 30, the groups were switched over for a second month. RESULTS: At baseline, aspartate aminotransferase and alanine aminotransferase were lower in patients drinking 3-5 (Group B) than 0-2 cups/day (Group A) (56 ± 6 vs 74 ± 11/60 ± 3 vs 73 ± 7 U/L p=0.05/p=0.04, respectively). HCV-RNA levels were significantly higher in Group B [(6.2 ± 1.5) × 10(5)vs (3.9 ± 1.0) × 10(5)UI/mL, p=0.05]. During coffee intake, 8-hydroxydeoxyguanosine and collagen levels were significantly lower than during abstinence (15 ± 3 vs 44 ± 16 8-hydroxydeoxyguanosine/10(5)deoxyguanosine, p=0.05 and 56 ± 9 vs 86 ± 21 ng/mL, p=0.04). Telomere length was significantly higher in patients during coffee intake (0.68 ± 0.06 vs 0.48 ± 0.04 Arbitrary Units, p=0.006). Telomere length and 8-hydroxydeoxyguanosine were inversely correlated. CONCLUSION: In chronic hepatitis C coffee consumption induces a reduction in oxidative damage, correlated with increased telomere length and apoptosis, with lower collagen synthesis, factors that probably mediate the protection exerted by coffee with respect to disease progression.

We performed a comprehensive literature review and meta-analysis to better quantify this association. METHODS: We identified all potentially relevant articles by searching MEDLINE, EMBASE, Cochrane Library, Web of Science, SCOPUS, and CINAHL (until February 2013). The keywords \"coffee,\" \"caffeine,\" \"drink,\" and \"beverage\" were used as the exposure factors, and the keyword \"fracture\" was used as the outcome factor. We determined the overall relative risk (RR) and confidence interval (CI) for the highest and lowest levels of coffee consumption. A dose-response analysis was performed to assess the risk of fractures based on the level of coffee consumption. RESULTS: We included 253,514 participants with 12,939 fracture cases from 9 cohort and 6 case-control studies. The estimated RR of fractures at the highest level of coffee consumption was 1.14 (95% CI: 1.05-1.24; I(2)=0.0%) in women and 0.76 (95% CI: 0.62-0.94; I(2)=7.3%) in men.

However, studies that analyzed prospectively the relation of coffee or caffeine consumption and depression risk are scarce. Methods A total of 50,739 U.S. women (mean age=63 years) free from depressive symptoms at baseline (1996) were prospectively followed until 2006. Caffeine and coffee consumption, and other caffeinated and decaffeinated beverages, were obtained from validated questionnaires completed between 1980 through 2002 and computed as cumulative average of consumption with a 2-year latency applied. Clinical depression was defined as reporting both physician-diagnosed depression and antidepressant use. Relative risks of clinical depression were estimate using Cox proportional hazards regression models. Results During 10 years of follow-up (1996–2006), 2,607 incident cases of depression were identified. Compared to women consuming caffeinated coffee less frequently (≤1 cup/wk), multivariate relative risk of depression was 0.85 (95% confidence interval [CI], 0.75 to 0.95) for those consuming 2–3 cups/d and 0.80 (95%CI, 0.64 to 0.99; P trend <0.001) for those consuming ≥4 cups/d.

There are important practical differences between the development of public health nutrition guidelines and guidelines for clinical practice. While the gold standard for evidence for clinical practice guidelines is a meta-analysis of a number of randomised controlled trials, this is often unrealistic and sometimes unethical for the evaluation of public health nutrition interventions. Hence, epidemiological studies make up the bulk of evidence for nutrition guidelines. Tea and coffee are an interesting case study in relation to this issue. They are two of the most commonly consumed beverages worldwide, yet there is little dietary advice on their use. The evidence for a relationship between coffee or tea consumption and several diseases is discussed. The available studies, predominantly epidemiological, together with animal and in vitro studies, indicate that coffee and tea are both safe beverages. However, tea is the healthier option because it has a possible role in the prevention of several cancers and CVD. While the evidence for such relationships is not strong, the public will continue to drink both tea and coffee, and will continue to ask nutritionists to make recommendations. It is therefore argued that advice should be given on the best available data, as waiting for complete data to become available could have severe consequences for public health.", "title": "Tea or coffee?

Recent published work and the report of an initial IAEA consultation in the area gave grounds for such concerns. There is a significant level of inappropriate usage, and, in some cases, a poor level of awareness of dose and risk among some key groups involved. This article aims to address this. Methods The IAEA convened a second group of experts in November 2008 to review practical and achievable actions that might lead to more effective justification. Results This report summarises the matters that this group considered and the outcome of their deliberations. There is a need for improved communication, both within professions and between professionals on one hand, and between professionals and the patients/public on the other. Coupled with this, the issue of consent to imaging procedures was revisited. The need for good evidence-based referral guidelines or criteria of acceptability was emphasised, as was the need for their global adaptation and dissemination. Conclusion Clinical audit was regarded as a key tool in ensuring that justification becomes an effective, transparent and accountable part of normal radiological practice.

The authors highlight an important policy document issued jointly by the National Cancer Institute and the Society for Pediatric Radiology--specifically, its conclusion that a small dose from CT represents \"a public health concern.\" Finally, the article identifies several contentious issues and proposes policy initiatives that, if implemented, could result in significant reductions of future radiogenic cancers and chronic injuries.

MATERIALS AND METHODS: Organ doses as a function of age-at-diagnosis were estimated for common CT examinations, and estimated attributable lifetime cancer mortality risks (per unit dose) for different organ sites were applied. Standard models that assume a linear extrapolation of risks from intermediate to low doses were applied. On the basis of current standard practice, the same exposures (milliampere-seconds) were assumed, independent of age. RESULTS: The larger doses and increased lifetime radiation risks in children produce a sharp increase, relative to adults, in estimated risk from CT. Estimated lifetime cancer mortality risks attributable to the radiation exposure from a CT in a 1-year-old are 0.18% (abdominal) and 0.07% (head)-an order of magnitude higher than for adults-although those figures still represent a small increase in cancer mortality over the natrual background rate. In the United States, of approximately 600,000 abdominal and head CT examinations annually performed in children under the age of 15 years, a rough estimate is that 500 of these individuals might ultimately die from cancer attributable to the CT radiation. CONCLUSION: The best available risk estimates suggest that pediatric CT will result in significantly increased lifetime radiation risk over adult CT, both because of the increased dose per milliampere-second, and the increased lifetime risk per unit dose. Lower milliampere-second settings can be used for children without significant loss of information. Although the risk-benefit balance is still strongly tilted toward benefit, because the frequency of pediatric CT examinations is rapidly increasing, estimates that quantitative lifetime radiation risks for children undergoing CT are not negligible may stimulate more active reduction of CT exposure settings in pediatric patients.", "title": "Estimated risks of radiation-induced fatal cancer from pediatric CT." }, { "docid": "MED-3627", "text": "BACKGROUND: The use of computed tomographic (CT) scans in the United States (US) has increased more than 3-fold since 1993 to approximately 70 million scans annually. Despite the great medical benefits, there is concern about the potential radiation-related cancer risk. We conducted detailed estimates of the future cancer risks from current CT scan use in the US according to age, sex, and scan type. METHODS: Risk models based on the National Research Council's \"Biological Effects of Ionizing Radiation\" report and organ-specific radiation doses derived from a national survey were used to estimate age-specific cancer risks for each scan type. These models were combined with age- and sex-specific scan frequencies for the US in 2007 obtained from survey and insurance claims data. We estimated the mean number of radiation-related incident cancers with 95% uncertainty limits (UL) using Monte Carlo simulations. RESULTS: Overall, we estimated that approximately 29 000 (95% UL, 15 000-45 000) future cancers could be related to CT scans performed in the US in 2007. The largest contributions were from scans of the abdomen and pelvis (n = 14 000) (95% UL, 6900-25 000), chest (n = 4100) (95% UL, 1900-8100), and head (n = 4000) (95% UL, 1100-8700), as well as from chest CT angiography (n = 2700) (95% UL, 1300-5000). One-third of the projected cancers were due to scans performed at the ages of 35 to 54 years compared with 15% due to scans performed at ages younger than 18 years, and 66% were in females. CONCLUSIONS: These detailed estimates highlight several areas of CT scan use that make large contributions to the total cancer risk, including several scan types and age groups with a high frequency of use or scans involving relatively high doses, in which risk-reduction efforts may be warranted.", "title": "Projected cancer risks from computed tomographic scans performed in the United States in 2007." }, { "docid": "MED-3625", "text": "Short abstract Radiological and nuclear medicine examinations confer a definite (albeit low) long term risk of cancer, but patients undergoing such examinations often receive no or inaccurate information about these risks.

These findings were further analyzed by specific anti-albumin IgE titrations and cross-inhibition experiments. Cat serum albumin cDNA was obtained from cat liver, and the corresponding amino acid sequence was deduced and compared to the known porcine and human serum albumin sequences. Inhibition experiments showed that the spectrum of IgE reactivity to cat serum albumin completely contained IgE reactivity to porcine serum albumin, suggesting that sensitization to cat was the primary event. In two cohorts of cat-allergic persons, the frequency of sensitization to cat serum albumin was found to lie between 14% and 23%. Sensitization to porcine albumin was found to lie between 3% and 10%.

In rodents and newborn humans, brown adipose tissue helps regulate energy expenditure by thermogenesis mediated by the expression of uncoupling protein 1 (UCP1), but brown adipose tissue has been considered to have no physiologic relevance in adult humans. METHODS We analyzed 3640 consecutive 18F-fluorodeoxyglucose (18F-FDG) positron-emission tomographic and computed tomographic (PET–CT) scans performed for various diagnostic reasons in 1972 patients for the presence of substantial depots of putative brown adipose tissue. Such depots were defined as collections of tissue that were more than 4 mm in diameter, had the density of adipose tissue according to CT, and had maximal standardized uptake values of 18F-FDG of at least 2.0 g per milliliter, indicating high metabolic activity. Clinical indexes were recorded and compared with those of date-matched controls. Immunostaining for UCP1 was performed on biopsy specimens from the neck and supraclavicular regions in patients undergoing surgery. RESULTS Substantial depots of brown adipose tissue were identified by PET–CT in a region extending from the anterior neck to the thorax. Tissue from this region had UCP1-immunopositive, multilocular adipocytes indicating brown adipose tissue. Positive scans were seen in 76 of 1013 women (7.5%) and 30 of 959 men (3.1%), corresponding to a female:male ratio greater than 2:1 (P<0.001). Women also had a greater mass of brown adipose tissue and higher 18F-FDG uptake activity. The probability of the detection of brown adipose tissue was inversely correlated with years of age (P<0.001), outdoor temperature at the time of the scan (P= 0.02), beta-blocker use (P<0.001), and among older patients, body-mass index (P = 0.007). CONCLUSIONS Defined regions of functionally active brown adipose tissue are present in adult humans, are more frequent in women than in men, and may be quantified noninvasively with the use of 18F-FDG PET–CT. Most important, the amount of brown adipose tissue is inversely correlated with body-mass index, especially in older people, suggesting a potential role of brown adipose tissue in adult human metabolism.", "title": "Identification and Importance of Brown Adipose Tissue in Adult Humans" }, { "docid": "MED-3983", "text": "This study was aimed at determining the molecular epidemiology of rabies virus (RABV) circulating in Vietnam. Intra vitam samples (saliva and cerebrospinal fluid) were collected from 31 patients who were believed to have rabies and were admitted to hospitals in northern provinces of Vietnam. Brain samples were collected from 176 sick or furious rabid dogs from all over the country. The human and canine samples were subjected to reverse transcription-polymerase chain reaction analysis. The findings showed that 23 patients tested positive for RABV. Interestingly, 5 rabies patients did not have any history of dog or cat bites, but they had an experience of butchering dogs or cats, or consuming their meat. RABV was also detected in 2 of the 100 sick dogs from slaughterhouses. Molecular epidemiological analysis of 27 RABV strains showed that these viruses could be classified into two groups. The RABVs classified into Group 1 were distributed throughout Vietnam and had sequence similarity with the strains from China, Thailand, Malaysia, and the Philippines. However, the RABVs classified into Group 2 were only found in the northern provinces of Vietnam and showed high sequence similarity with the strain from southern China. This finding suggested the recent influx of Group 2 RABVs between Vietnam and China across the border. Although the incidence of rabies due to circulating RABVs in slaughterhouses is less common than that due to dog bite, the national program for rabies control and prevention in Vietnam should include monitoring of the health of dogs meant for human consumption and vaccination for workers at dog slaughterhouses.

Pan retinal photocoagulation (PRP) has provided an effective treatment to decrease the risk of severe vision loss in patients with proliferative diabetic retinopathy for the past four decades. Pattern scan laser (PASCAL) was developed to minimize the side effects of PRP. The purpose of this review is to discuss the differences between the traditional argon laser and the PASCAL. RECENT FINDINGS: PASCAL can achieve comparable results with the conventional argon PRP in the treatment of patients with diabetic retinopathy. The PASCAL delivery system creates well aligned arrays of retinal lesions in a shorter period. PASCAL provides amore comfortable profile when compared to the argon laser. SUMMARY: The PASCAL is now being substituted for the conventional argon laser for PRP in many clinics. Ophthalmologists should keep in mind that adjusting the PASCAL settings (including the duration, number, and size of laser burns) might become necessary to maintain regression and eliminate recurrence of neovascularization in patients with proliferative diabetic retinopathy.

Among a number of Ca2+ sensors in the eukaryotic cell, calmodulin (CaM) is the most widespread and the best studied. Employing the mRNA display technique, we have scanned the human proteome for CaM-binding proteins and have identified and characterized a large number of both known and previously uncharacterized proteins that interact with CaM in a Ca2+-dependent manner. The interactions of several identified proteins with Ca2+/CaM were confirmed by using pull-down assays and coimmunoprecipitation. Many of the CaM-binding proteins identified belong to protein families such as the DEAD/H box proteins, ribosomal proteins, proteasome 26S subunits, and deubiquitinating enzymes, suggesting the possible involvement of Ca2+/CaM in different signaling pathways.

Aim To define the underlying cellular mechanisms with special attention to tight junctions. Methods Biopsy specimens from the sigmoid colon of patients with mild to moderately active or inactive Crohn's disease were studied in Ussing chambers, and barrier function was determined by impedance analysis and conductance scanning. Tight junction structure was analysed by freeze fracture electron microscopy, and tight junction proteins were investigated immunohistochemically by confocal laser scanning microscopy and quantified in immunoblots. Epithelial apoptosis was analysed in terminal deoxynucleotidyl transferase‐mediated deoxyuridine triphosphate nick‐end labelling and 4′,6‐diamidino‐2‐phenylindole staining. Results Patients with active Crohn's disease showed an impaired intestinal barrier function as indicated by a distinct reduction in epithelial resistance. As distribution of conductivity was even, focal epithelial lesions (eg, microerosions) did not contribute to barrier dysfunction. Instead, freeze fracture electron microscopy analysis showed reduced and discontinuous tight junction strands. Occludin and the sealing tight junction proteins claudin 5 and claudin 8 were downregulated and redistributed off the tight junction, whereas the pore‐forming tight junctions protein claudin 2 was strongly upregulated, which constitute the molecular basis of tight junction changes. Other claudins were unchanged (claudins 1, 4 and 7) or not detectable in sigmoid colon (claudins 11, 12, 14, 15 and 16). Claudin 2 upregulation was less pronounced in active Crohn's disease compared with active ulcerative colitis and was inducible by tumour necrosis factor α. As a second source of impaired barrier function, epithelial apoptosis was distinctly increased in active Crohn's disease (mean (SD) 5.2 (0.5)% v 1.9 (0.2)% in control). By contrast, barrier function, tight junction proteins and apoptosis were unaffected in Crohn's disease in remission.

Objective To determine whether supplementation with B vitamins that lower levels of plasma total homocysteine can slow the rate of brain atrophy in subjects with mild cognitive impairment in a randomised controlled trial (VITACOG, ISRCTN 94410159). Methods and Findings Single-center, randomized, double-blind controlled trial of high-dose folic acid, vitamins B6 and B12 in 271 individuals (of 646 screened) over 70 y old with mild cognitive impairment. A subset (187) volunteered to have cranial MRI scans at the start and finish of the study. Participants were randomly assigned to two groups of equal size, one treated with folic acid (0.8 mg/d), vitamin B12 (0.5 mg/d) and vitamin B6 (20 mg/d), the other with placebo; treatment was for 24 months. The main outcome measure was the change in the rate of atrophy of the whole brain assessed by serial volumetric MRI scans. Results A total of 168 participants (85 in active treatment group; 83 receiving placebo) completed the MRI section of the trial. The mean rate of brain atrophy per year was 0.76% [95% CI, 0.63–0.90] in the active treatment group and 1.08% [0.94–1.22] in the placebo group (P = 0.001). The treatment response was related to baseline homocysteine levels: the rate of atrophy in participants with homocysteine >13 µmol/L was 53% lower in the active treatment group (P = 0.001). A greater rate of atrophy was associated with a lower final cognitive test scores. There was no difference in serious adverse events according to treatment category. Conclusions and Significance The accelerated rate of brain atrophy in elderly with mild cognitive impairment can be slowed by treatment with homocysteine-lowering B vitamins. Sixteen percent of those over 70 y old have mild cognitive impairment and half of these develop Alzheimer's disease. Since accelerated brain atrophy is a characteristic of subjects with mild cognitive impairment who convert to Alzheimer's disease, trials are needed to see if the same treatment will delay the development of Alzheimer's disease.

Recent research has identified a novel cause for “idiopathic” allergic reactions; immunoglobulin E (IgE) antibody specific for the carbohydrate galactose-α-1,3-galactose (α-Gal) has been associated with delayed urticaria and anaphylaxis that occurs 3 to 6 hours after eating beef, pork, or lamb. We sought to determine whether IgE antibody to α-Gal was present in sera of pediatric patients who reported idiopathic anaphylaxis or urticaria. METHODS: Patients aged 4 to 17 were enrolled in an institutional review board–approved protocol at the University of Virginia and private practice allergy offices in Lynchburg, VA. Sera was obtained and analyzed by ImmunoCAP for total IgE and specific IgE to α-Gal, beef, pork, cat epithelium and dander, Fel d 1, dog dander, and milk. RESULTS: Forty-five pediatric patients were identified who had both clinical histories supporting delayed anaphylaxis or urticaria to mammalian meat and IgE antibody specific for α-Gal. In addition, most of these cases had a history of tick bites within the past year, which itched and persisted. CONCLUSIONS: A novel form of anaphylaxis and urticaria that occurs 3 to 6 hours after eating mammalian meat is not uncommon among children in our area. Identification of these cases may not be straightforward and diagnosis is best confirmed by specific testing, which should certainly be considered for children living in the area where the Lone Star tick is common.", "title": "Galactose-α-1,3-galactose and Delayed Anaphylaxis, Angioedema, and Urticaria in Children" }, { "docid": "MED-3478", "text": "Colon cancer is one of the serious health problems in most developed countries and its incidence rate is increasing in India.

We have characterized the viral transcript and determined the complete sequence of the genome of Commelina mellow mottle virus (CoYMV), a member of this group. Analysis of the viral transcript indicates that the virus encodes a single terminally-redundant genome-length plus 120 nucleotide transcript. A fraction of the transcripts is polyadenylated, although the majority of the transcript is not polyadenylated. Analysis of the genome sequence indicates that the genome is 7489 bp in size and that the transcribed strand contains three open reading frames capable of encoding proteins of 23, 15 and 216 kd. The function of the 25 and 15 kd proteins is unknown. Similarities between the 216 kd polypeptide and the cauliflower mosaic virus coat protein and protease/reverse transcriptase polyprotein suggest that the 216 kd polypeptide is a polyprotein that is proteolytically processed to yield the virion coat protein, a protease, and replicase (reverse transcriptase and ribonuclease H). Each strand of the CoYMV genome is interrupted by site-specific discontinuities. The locations of the 5'-ends of these discontinuities, and the presence and location of a region on the CoYMV transcript capable of annealing with the 3'-end of cytosolic initiator methionine tRNA are consistent with replication by reverse transcription.

Reflecting this range of roles, simple linear strings of RNA—made up of uracil, guanine, cytosine, and adenine—form a variety of complex three-dimensional structures. Just as proteins form distinct structural motifs such as zinc fingers and beta barrels, certain structures are also commonly adopted by RNA molecules. Among the most prevalent RNA structures is a motif known as the pseudoknot. First recognized in the turnip yellow mosaic virus [1], a pseudoknot is an RNA structure that is minimally composed of two helical segments connected by single-stranded regions or loops (Figure 1). Although several distinct folding topologies of pseudoknots exist, the best characterized is the H type. In the H-type fold, the bases in the loop of a hairpin form intramolecular pairs with bases outside of the stem (Figure 1A and ​and1B).1B). This causes the formation of a second stem and loop, resulting in a pseudoknot with two stems and two loops (Figure 1C). The two stems are able to stack on top of each other to form a quasi-continuous helix with one continuous and one discontinuous strand. The single-stranded loop regions often interact with the adjacent stems (loop 1–stem 2 or loop 2–stem 1) to form hydrogen bonds and to participate in the overall structure of the molecule. Hence, this relatively simple fold can yield very complex and stable RNA structures. Due to variation of the lengths of the loops and stems, as well as the types of interactions between them, pseudoknots represent a structurally diverse group. It is fitting that they play a variety of diverse roles in biology. These roles include forming the catalytic core of various ribozymes [2,3], self-splicing introns [4], and telomerase [5].

Egyptians believed that cancer occurred at the will of the gods. Hippocrates believed human disease resulted from an imbalance of the four humors: blood, phlegm, yellow bile, and black bile with cancer being caused by excess black bile. The lymph theory of cancer replaced the humoral theory and the blastema theory replaced the lymph theory. Rudolph Virchow was the first to recognize that cancer cells like all cells came from other cells and believed chronic irritation caused cancer. At the same time there was a belief that trauma caused cancer, though it never evolved after many experiments inducing trauma. The birth of virology occurred in 1892 when Dimitri Ivanofsky demonstrated that diseased tobacco plants remained infective after filtering their sap through a filter that trapped bacteria. Martinus Beijerinck would call the tiny infective agent a virus and both Dimitri Ivanofsky and Marinus Beijerinck would become the fathers of virology.

DESIGN Epidemiological investigations conducted after a family cluster of two patients with avian H7N9 in March 2013. SETTING Wuxi, Eastern China. PARTICIPANTS Two patients, their close contacts, and relevant environments. Samples from the patients and environments were collected and tested by real time reverse transcriptase-polymerase chain reaction (rRT-PCR), viral culture, and haemagglutination inhibition assay. Any contacts who became ill had samples tested for avian H7N9 by rRT-PCR. Paired serum samples were obtained from contacts for serological testing by haemagglutination inhibition assays. MAIN OUTCOMES MEASURES Clinical data, history of exposure before the onset of illnesses, and results of laboratory testing of pathogens and further analysis of sequences and phylogenetic tree to isolated strains. RESULTS The index patient became ill five to six days after his last exposure to poultry. The second patient, his daughter aged 32, who provided unprotected bedside care in the hospital, had no known exposure to poultry. She developed symptoms six days after her last contact with her father. Two strains were isolated successfully from the two patients. Genome sequence and analyses of phylogenetic trees showed that both viruses were almost genetically identical. Forty three close contacts of both patients were identified. One had mild illness but had negative results for avian H7N9 by rRT-PCR. All 43 close contacts tested negative for haemagglutination inhibition antibodies specific for avian H7N9.

Here we have performed whole-genome bisulfite sequencing of normal B-cells, activated B-cells, and EBV-immortalized B-cells from the same three individuals, in order to identify the impact of transformation on the methylome. Surprisingly, large-scale hypomethylated blocks comprising two-thirds of the genome were induced by EBV immortalization but not by B-cell activation per se.

Here we show that the methylation status of endogenous capped mRNA at the 5'-terminal nucleotide (N1) was crucial to prevent RIG-I activation. Moreover, we identified a single conserved amino acid (H830) in the RIG-I RNA binding pocket as the mediator of steric exclusion of N1-2'O-methylated RNA.

The transcription of the DRADA gene driven by the putative promoter region, which contains no typical TATA or CCAAT box-like sequences, is initiated at multiple sites, 164 to 216 nucleotides upstream of the translation initiation codon. The three dsRNA binding motifs (DRBM), 70 amino acid residues long, are each encoded by two exons plus an intervening sequence that interrupts the motif at the identical amino acid position.

The polyprotein P123 is produced when translation terminates at an opal termination codon between nsP3 and nsP4. The polyprotein P1234 is produced when translational readthrough occurs or when the opal termination codon has been replaced by a sense codon in the alphavirus genome. Evolutionary pressures appear to have maintained genomic sequences encoding both a stop codon (opal) and an open reading frame (arginine) as a general feature of the O'nyong-nyong virus (ONNV) genome, indicating that both are required at some point. Alternate replication of ONNVs in both vertebrate and invertebrate hosts may determine predominance of a particular codon at this locus in the viral quasispecies. However, no systematic study has previously tested this hypothesis in whole animals. We report here the results of the first study to investigate in a natural mosquito host the functional significance of the opal stop codon in an alphavirus genome. We used a full-length cDNA clone of ONNV to construct a series of mutants in which the arginine between nsP3 and nsP4 was replaced with an opal, ochre, or amber stop codon. The presence of an opal stop codon upstream of nsP4 nearly doubled (75.5%) the infectivity of ONNV over that of virus possessing a codon for the amino acid arginine at the corresponding position (39.8%). Although the frequency with which the opal virus disseminated from the mosquito midgut did not differ significantly from that of the arginine virus on days 8 and 10, dissemination did began earlier in mosquitoes infected with the opal virus. Although a clear fitness advantage is provided to ONNV by the presence of an opal codon between nsP3 and nsP4 in Anopheles gambiae, sequence analysis of ONNV RNA extracted from mosquito bodies and heads indicated codon usage at this position corresponded with that of the virus administered in the blood meal. These results suggest that while selection of ONNV variants is occurring, de novo mutation at the position between nsP3 and nsP4 does not readily occur in the mosquito. Taken together, these results suggest that the primary fitness advantage provided to ONNV by the presence of an opal codon between nsP3 and nsP4 is related to mosquito infectivity.", "title": "Effects of an opal termination codon preceding the nsP4 gene sequence in the O'Nyong-Nyong virus genome on Anopheles gambiae infectivity." }, { "docid": "4323449", "text": "More than forty per cent of the mammalian genome is derived from retroelements, of which about one-quarter are endogenous retroviruses (ERVs). Some are still active, notably in mice the highly polymorphic early transposon (ETn)/MusD and intracisternal A-type particles (IAP).

Two lines of evidence suggest that KAP1-mediated repression could contribute to the control of ERVs: first, KAP1 can trigger permanent gene silencing during early embryogenesis, and second, a KAP1 complex silences the retrovirus murine leukaemia virus in embryonic cells. Consistent with this hypothesis, here we show that KAP1 deletion leads to a marked upregulation of a range of ERVs, in particular IAP elements, in mouse embryonic stem (ES) cells and in early embryos. We further demonstrate that KAP1 acts synergistically with DNA methylation to silence IAP elements, and that it is enriched at the 5′ untranslated region (5′UTR) of IAP genomes, where KAP1 deletion leads to the loss of histone 3 lysine 9 trimethylation (H3K9me3), a hallmark of KAP1-mediated repression.

A key challenge in transcript quantification from RNA-Seq data is the handling of reads that map to multiple genes or isoforms. This issue is particularly important for quantification with de novo transcriptome assemblies in the absence of sequenced genomes, as it is difficult to determine which transcripts are isoforms of the same gene. A second significant issue is the design of RNA-Seq experiments, in terms of the number of reads, read length, and whether reads come from one or both ends of cDNA fragments. RESULTS We present RSEM, an user-friendly software package for quantifying gene and isoform abundances from single-end or paired-end RNA-Seq data. RSEM outputs abundance estimates, 95% credibility intervals, and visualization files and can also simulate RNA-Seq data. In contrast to other existing tools, the software does not require a reference genome. Thus, in combination with a de novo transcriptome assembler, RSEM enables accurate transcript quantification for species without sequenced genomes. On simulated and real data sets, RSEM has superior or comparable performance to quantification methods that rely on a reference genome. Taking advantage of RSEM's ability to effectively use ambiguously-mapping reads, we show that accurate gene-level abundance estimates are best obtained with large numbers of short single-end reads. On the other hand, estimates of the relative frequencies of isoforms within single genes may be improved through the use of paired-end reads, depending on the number of possible splice forms for each gene. CONCLUSIONS RSEM is an accurate and user-friendly software tool for quantifying transcript abundances from RNA-Seq data. As it does not rely on the existence of a reference genome, it is particularly useful for quantification with de novo transcriptome assemblies.

Nonadditive genetic variance made a significant contribution to the estimates of heritability, particularly among men. Of the potential environmental influences, only those unique to the individual and not those shared by family members were important, contributing about 30 percent of the variance. Sharing the same childhood environment did not contribute to the similarity of the body-mass index of twins later in life.

Banana streak Obino l'Ewai virus has severely hindered international banana (Musa spp.) breeding programmes, as new hybrids are frequently infected with this virus, curtailing any further exploitation. This infection is thought to arise from viral DNA integrated in the nuclear genome of Musa balbisiana (B genome), one of the wild species contributing to many of the banana cultivars currently grown. In order to determine whether the DNA of other badnavirus species is integrated in the Musa genome, PCR-amplified DNA fragments from Musa acuminata, M. balbisiana and Musa schizocarpa, as well as cultivars 'Obino l'Ewai' and 'Klue Tiparot', were cloned. In total, 103 clones were sequenced and all had similarity to open reading frame III in the badnavirus genome, although there was remarkable variation, with 36 distinct sequences being recognized with less than 85 % nucleotide identity to each other. There was no commonality in the sequences amplified from M. acuminata and M. balbisiana, suggesting that integration occurred following the separation of these species. Analysis of rates of non-synonymous and synonymous substitution suggested that the integrated sequences evolved under a high degree of selective constraint as might be expected for a living badnavirus, and that each distinct sequence resulted from an independent integration event.", "title": "Banana contains a diverse array of endogenous badnaviruses." }, { "docid": "4402497", "text": "Innate immune defences are essential for the control of virus infection and are triggered through host recognition of viral macromolecular motifs known as pathogen-associated molecular patterns (PAMPs). Hepatitis C virus (HCV) is an RNA virus that replicates in the liver, and infects 200 million people worldwide. Infection is regulated by hepatic immune defences triggered by the cellular RIG-I helicase. RIG-I binds PAMP RNA and signals interferon regulatory factor 3 activation to induce the expression of interferon-α/β and antiviral/interferon-stimulated genes (ISGs) that limit infection. Here we identify the polyuridine motif of the HCV genome 3′ non-translated region and its replication intermediate as the PAMP substrate of RIG-I, and show that this and similar homopolyuridine or homopolyriboadenine motifs present in the genomes of RNA viruses are the chief feature of RIG-I recognition and immune triggering in human and murine cells. 5′ terminal triphosphate on the PAMP RNA was necessary but not sufficient for RIG-I binding, which was primarily dependent on homopolymeric ribonucleotide composition, linear structure and length. The HCV PAMP RNA stimulated RIG-I-dependent signalling to induce a hepatic innate immune response in vivo, and triggered interferon and ISG expression to suppress HCV infection in vitro. These results provide a conceptual advance by defining specific homopolymeric RNA motifs within the genome of HCV and other RNA viruses as the PAMP substrate of RIG-I, and demonstrate immunogenic features of the PAMP–RIG-I interaction that could be used as an immune adjuvant for vaccine and immunotherapy approaches.", "title": "Innate immunity induced by composition-dependent RIG-I recognition of hepatitis C virus RNA" }, { "docid": "11016410", "text": "Within hosts, RNA viruses form populations that are genetically and phenotypically complex. Heterogeneity in RNA virus genomes arises due to error-prone replication and is reduced by stochastic and selective mechanisms that are incompletely understood. Defining how natural selection shapes RNA virus populations is critical because it can inform treatment paradigms and enhance control efforts. We allowed West Nile virus (WNV) to replicate in wild-caught American crows, house sparrows and American robins to assess how natural selection shapes RNA virus populations in ecologically relevant hosts that differ in susceptibility to virus-induced mortality. After five sequential passages in each bird species, we examined the phenotype and population diversity of WNV through fitness competition assays and next generation sequencing. We demonstrate that fitness gains occur in a species-specific manner, with the greatest replicative fitness gains in robin-passaged WNV and the least in WNV passaged in crows. Sequencing data revealed that intrahost WNV populations were strongly influenced by purifying selection and the overall complexity of the viral populations was similar among passaged hosts. However, the selective pressures that control WNV populations seem to be bird species-dependent. Specifically, crow-passaged WNV populations contained the most unique mutations (~1.7× more than sparrows, ~3.4× more than robins) and defective genomes (~1.4× greater than sparrows, ~2.7× greater than robins), but the lowest average mutation frequency (about equal to sparrows, ~2.6× lower than robins). Therefore, our data suggest that WNV replication in the most disease-susceptible bird species is positively associated with virus mutational tolerance, likely via complementation, and negatively associated with the strength of selection. These differences in genetic composition most likely have distinct phenotypic consequences for the virus populations. Taken together, these results reveal important insights into how different hosts may contribute to the emergence of RNA viruses.", "title": "Experimental Evolution of an RNA Virus in Wild Birds: Evidence for Host-Dependent Impacts on Population Structure and Competitive Fitness" }, { "docid": "4231060", "text": "The transforming gene (src) of avian sarcoma virus (ASV) and adjacent regions of the viral genome have been isolated by molecular cloning of viral DNA.

GS-9620 was previously shown to induce prolonged suppression of serum viral DNA and antigens in the woodchuck and chimpanzee models of CHB. Herein, we investigated the molecular mechanisms that contribute to the antiviral response to GS-9620 using in vitro models of hepatitis B virus (HBV) infection. METHODS Cryopreserved primary human hepatocytes (PHH) and differentiated HepaRG (dHepaRG) cells were infected with HBV and treated with GS-9620, conditioned media from human peripheral blood mononuclear cells treated with GS-9620 (GS-9620 conditioned media [GS-9620-CM]), or other innate immune stimuli. The antiviral and transcriptional response to these agents was determined. RESULTS GS-9620 had no antiviral activity in HBV-infected PHH, consistent with low level TLR7 mRNA expression in human hepatocytes. In contrast, GS-9620-CM induced prolonged reduction of HBV DNA, RNA, and antigen levels in PHH and dHepaRG cells via a type I interferon (IFN)-dependent mechanism. GS-9620-CM did not reduce covalently closed circular DNA (cccDNA) levels in either cell type. Transcriptional profiling demonstrated that GS-9620-CM strongly induced various HBV restriction factors - although not APOBEC3A or the Smc5/6 complex - and indicated that established HBV infection does not modulate innate immune sensing or signaling in cryopreserved PHH. GS-9620-CM also induced expression of immunoproteasome subunits and enhanced presentation of an immunodominant viral peptide in HBV-infected PHH. CONCLUSIONS Type I IFN induced by GS-9620 durably suppressed HBV in human hepatocytes without reducing cccDNA levels. Moreover, HBV antigen presentation was enhanced, suggesting additional components of the TLR7-induced immune response played a role in the antiviral response to GS-9620 in animal models of CHB. LAY SUMMARY GS-9620 is a drug currently being tested in clinical trials for the treatment of chronic hepatitis B virus (HBV) infection. GS-9620 has previously been shown to suppress HBV in various animal models, but the underlying antiviral mechanisms were not completely understood. In this study, we determined that GS-9620 does not directly activate antiviral pathways in human liver cells, but can induce prolonged suppression of HBV via induction of an antiviral cytokine called interferon. However, interferon did not destroy the HBV genome, suggesting that other parts of the immune response (e.g. activation of immune cells that kill infected cells) also play an important role in the antiviral response to GS-9620.", "title": "Toll-like receptor 7 agonist GS-9620 induces prolonged inhibition of HBV via a type I interferon-dependent mechanism." }, { "docid": "10494012", "text": "Amodel that explains both the origin and sporadic nature of cancer argues that cancer cells are a chance result of events that cause genomic and epigenetic variability. The prevailing view is that these events are mutations that affect chromosome segregation or stability. However, genomic and epigenetic variability is also triggered by cell fusion, which is often caused by viruses. Yet, cells fused by viruses are considered harmless because they die. We provide evidence that a primate virus uses both viral and exosomal proteins involved in cell fusion to produce transformed proliferating human cells. Although normal cells indeed fail to proliferate after fusion, expression of an oncogene or a mutated tumor suppressor p53 in just one of the fusion partners is sufficient to produce heterogeneous progeny.

Histidine kinases (HKs) phosphorylate and dephosphorylate their cognate response regulators (RRs) in response to stimuli. In general, these reactions appear to be highly specific and require an appropriate association between the HK and RR proteins. The Myxococcus xanthus genome encodes one of the largest repertoires of signaling proteins in bacteria (685 open reading frames [ORFs]), including at least 127 HKs and at least 143 RRs. Of these, 27 are bona fide NtrC-family response regulators, 21 of which are encoded adjacent to their predicted cognate kinases. Using system-wide profiling methods, we determined that the HK-NtrC RR pairs display a kinetic preference during both phosphotransfer and phosphatase functions, thereby defining cognate signaling systems in M. xanthus. Isothermal titration calorimetry measurements indicated that cognate HK-RR pairs interact with dissociation constants (Kd) of approximately 1 µM, while noncognate pairs had no measurable binding. Lastly, a chimera generated between the histidine kinase, CrdS, and HK1190 revealed that residues conferring phosphotransfer and phosphatase specificity dictate binding affinity, thereby establishing discrete protein-protein interactions which prevent cross talk. The data indicate that binding affinity is a critical parameter governing system-wide signaling fidelity for bacterial signal transduction proteins. IMPORTANCE Using in vitro phosphotransfer and phosphatase profiling assays and isothermal titration calorimetry, we have taken a system-wide approach to demonstrate specificity for a family of two-component signaling proteins in Myxococcus xanthus.

[ { "docid": "MED-4358", "text": "Summary Since their discovery almost a century ago, bacterial viruses (bacteriophages or ‘phages’) have been used to prevent and treat a multitude of bacterial infections (phage therapy: PT). In addition, they have been the basis for many advances in genetics and biochemistry. Phage therapy was performed on human subjects in the United States, Europe and Asia in the few decades following their discovery. However, Western countries largely abandoned PT in favour of antibiotics in the 1940s. The relatively recent renaissance of PT in the West can be attributed partly to the increasing prevalence of antibiotic resistance in human and animal pathogens. However, the stringent controls on human trials now required in the United States and Europe have led to a greater number of domestic animal and agricultural applications as an alternative to PT in man. This trend is set to continue, at least in the short term, with recent approval from the Food and Drug Administration allowing commercial phage treatments to be used in human food in the USA. Nevertheless, despite these significant milestones and the growing number of successful PT trials, significant obstacles remain to their widespread use in animals, food and ultimately medicine in many parts of the world. This review will provide a brief overview of the history of PT in the West and will summarize some of the key findings of phage biocontrol studies in animals and meat products.", "title": "Bacteriophage biocontrol in animals and meat products" }, { "docid": "MED-732", "text": "Sponge samples were taken from the carcases, meat, personnel and surfaces involved in stunning, slaughter and dressing/boning activities at three abattoirs, and from retail beef products.

We did a risk-factor analysis for the prevalence of antimicrobial resistant Campylobacter coli on 64 Swiss pig finishing farms. Between May and November 2001, 20 faecal samples per farm were collected from the floor of pens holding finishing pigs shortly before slaughter. Samples were pooled and cultured for Campylobacter species. Isolated Campylobacter strains were tested for resistance against selected antimicrobials. Additionally, information on herd health and management aspects was available from another study. Because data quality on the history of antimicrobial use on the farms was poor, only non-antimicrobial risk factors could be analysed. Statistical analyses were performed for resistance against ciprofloxacin, erythromycin, streptomycin, tetracycline, and for multiple resistance, which was defined as resistance to three or more antimicrobials. Risk factors for these outcomes--corrected for dependency of samples at herd level--were analysed in five generalised estimation-equation models. Prevalence of antimicrobial resistance among Campylobacter isolates was ciprofloxacin 26.1%, erythromycin 19.2%, streptomycin 78.0%, tetracycline 9.4%, and multiple resistance 6.5%. Important risk factors contributing to the prevalence of resistant strains were shortened tails, lameness, skin lesions, feed without whey, and ad libitum feeding. Multiple resistance was more likely in farms which only partially used an all-in-all-out system (OR = 37), or a continuous-flow system (OR = 3) compared to a strict all-in-all-out animal-flow. Presence of lameness (OR = 25), ill-thrift (OR = 15), and scratches at the shoulder (OR = 5) in the herd also increased the odds for multiple resistance.

Although common in Europe, CD is thought to be rare in the United States, where there are no large epidemiologic studies of its prevalence. The aim of this study was to determine the prevalence of CD in at-risk and not-at-risk groups in the United States. METHODS: Serum antigliadin antibodies and anti-endomysial antibodies (EMA) were measured. In EMA-positive subjects, human tissue transglutaminase IgA antibodies and CD-associated human leukocyte antigen DQ2/DQ8 haplotypes were determined. Intestinal biopsy was recommended and performed whenever possible for all EMA-positive subjects. A total of 13 145 subjects were screened: 4508 first-degree and 1275 second-degree relatives of patients with biopsy-proven CD, 3236 symptomatic patients (with either gastrointestinal symptoms or a disorder associated with CD), and 4126 not-at-risk individuals. RESULTS: In at-risk groups, the prevalence of CD was 1:22 in first-degree relatives, 1:39 in second-degree relatives, and 1:56 in symptomatic patients. The overall prevalence of CD in not-at-risk groups was 1:133. All the EMA-positive subjects who underwent intestinal biopsy had lesions consistent with CD. CONCLUSIONS: Our results suggest that CD occurs frequently not only in patients with gastrointestinal symptoms, but also in first- and second-degree relatives and patients with numerous common disorders even in the absence of gastrointestinal symptoms.

Diverse factors have been investigated as explanations for ST131's rapid and successful dissemination, including transmission through animal contact and consumption of food, as suggested by the detection of ST131 in a number of nonhuman species. For example, ST131 has recently been identified as a cause of clinical infection in companion animals and poultry, and both host groups have been confirmed as faecal carriers of ST131. Moreover, a high degree of similarity has been shown among certain ST131 isolates from humans, companion animals, and poultry based on resistance characteristics and genomic background and human and companion animal ST131 isolates tend to exhibit similar virulence genotypes. However, most ST131 isolates from poultry appear to possess specific virulence genes that are typically absent from human and companion animal isolates, including genes associated with avian pathogenic E. coli. Since the number of reported animal and food-associated ST131 isolates is quite small, the role of nonhuman host species in the emergence, dissemination, and transmission of ST131 to humans remains unclear. Nevertheless, given the profound public health importance of the emergent ST131 clonal group, even the limited available evidence indicates a pressing need for further careful study of this significant question.

However, mucosal damage develops gradually and patients may evince clinical symptoms before histologic changes appear. Endomysial antibodies are specific in predicting forthcoming villous atrophy. We hypothesized that patients with mild enteropathy but positive endomysial antibodies benefit from a gluten-free diet (GFD) similarly to patients with more severe enteropathy. METHODS: Small-bowel endoscopy together with clinical evaluations was performed in all together 70 consecutive adults with positive endomysial antibodies. Of these, 23 had only mild enteropathy (Marsh I-II) and they were randomized either to continue on a gluten-containing diet or start a GFD. After 1 year, clinical, serologic, and histologic evaluations were repeated. A total of 47 participants had small-bowel mucosal lesions compatible with celiac disease (Marsh III), and these served as disease controls. RESULTS: In the gluten-containing diet group (Marsh I-II) the small-bowel mucosal villous architecture deteriorated in all participants, and the symptoms and abnormal antibody titers persisted.

The clonality of the urine and fecal isolates of E. coli from the cystitis subjects was further evaluated by pulsed-field gel electrophoresis (PFGE). RESULTS: E. coli strains causing cystitis dominated the rectal flora of 7 of 9 patients. In the remaining 2 patients, similar clones comprised at least 20% of the fecal flora. Carriage of E. coli strains with a variety of urovirulence factors was quite common among healthy women. PFGE demonstrated that most of the isolates sharing the same serotypic characteristics and virulence factors in the urine and rectal swab samples from each subject were identical.

The objective of this study was to determine whether detection of childhood celiac disease by mass screening improves long-term health status and health-related quality of life. METHODS: We conducted a prospective 10-year follow-up study of 32 children who were aged 2 to 4 years, had celiac disease identified by mass screening, and had a gluten-free diet (19) or a normal gluten-containing diet (13). The follow-up included assessments of general health status, celiac disease-associated symptoms, celiac disease-associated serum antibodies, and health-related quality of life. RESULTS: Ten years after mass screening, 81% of the children were adhering to a gluten-free diet. The health status improved in 66% of the treated children: in 41% by early treatment and in 25% by prevention of the gluten-dependent symptoms that they developed after diagnosis. For 19% of the children, treatment after screening would not have improved their health status, because they had no symptoms at screening and have remained symptom-free while consuming gluten. The health-related quality of life of the children with symptoms improved significantly after 1 year of gluten-free diet. Ten years after screening, the health-related quality of life of the children with celiac disease was similar to that of the reference population. CONCLUSION: Identification by mass screening led 10 years later to health improvement in 66% of children without deterioration of generic health-related quality of life.

RECENT FINDINGS: Traditionally, total protein requirements for humans have been determined using nitrogen balance. The recent Dietary Reference Intake recommendations for mean and population-safe intakes of 0.66 and 0.8 g/kg/day, respectively, of high-quality protein in adult humans are based on a meta-analysis of nitrogen balance studies using single linear regression analysis. We reanalyzed existing nitrogen balance studies using two-phase linear regression analysis and obtained mean and safe protein requirements of 0.91 and 0.99 g/kg/day, respectively. The two-phase linear regression analysis is considered more appropriate for biological analysis of dose-response curves. Considering the inherent problems associated with the nitrogen balance method, we developed an alternative method, the indicator amino acid oxidation technique, to determine protein requirements The mean and population-safe requirements in adult men were determined to be 0.93 and 1.2 g/kg/day and are 41 and 50%, respectively, higher than the current Dietary Reference Intakes recommendations. SUMMARY: The indicator amino acid oxidation-based requirement values of 0.93 and 1.2 g protein/kg/day and the reanalysis of existing nitrogen balance studies are significantly higher than current recommendations.

Subjects received either dried plums (50 g b.d., fibre=6 gm/day) or psyllium (11 g b.d., fibre=6 gm/day) for 3 weeks each, in a crossover trial with a 1-week washout period. Subjects maintained a daily symptom and stool diary. Assessments included number of complete spontaneous bowel movements per week, global relief of constipation, stool consistency, straining, tolerability and taste. RESULTS: Forty constipated subjects (m/f=3/37, mean age=38 years) participated. The number of complete spontaneous bowel movements per week (primary outcome measure) and stool consistency scores improved significantly (P<0.05) with dried plums when compared to psyllium.

To overcome this problem, we developed a new form of curcumin (Theracurmin) and reported high plasma curcumin levels could be safely achieved after a single administration of Theracurmin in healthy volunteers. In this study, we aimed to evaluate the safety of repetitive administration of Theracurmin in cancer patients. METHODS: Pancreatic or biliary tract cancer patients who failed standard chemotherapy were eligible for this study. Based on our previous pharmacokinetic study, we selected Theracurmin containing 200 mg of curcumin (Level 1) as a starting dose, and the dose was safely escalated to Level 2, which contained 400 mg of curcumin. Theracurmin was orally administered every day with standard gemcitabine-based chemotherapy. In addition to safety and pharmacokinetics data, NF-κB activity, cytokine levels, efficacy, and quality-of-life score were evaluated.

The individuals that companies select to make these determinations may have financial conflicts of interest. OBJECTIVE: To determine the extent to which individuals selected by manufacturers to make GRAS determinations have conflicts of interest between their obligations to ensure that the use of the additive is safe and their financial relationships to the company. DESIGN Using conflict of interest criteria developed by a committee of the Institute of Medicine, we analyzed 451 GRAS notifications that were voluntarily submitted to the FDA between 1997 and 2012. MAIN OUTCOMES AND MEASURES: Number of GRAS notices submitted to the FDA; frequency of various types of relationships between decision maker and additive manufacturer; frequency of participation on GRAS panels by individuals; and number of GRAS safety determinations identified by the FDA that were not submitted to the agency. RESULTS: For the 451 GRAS notifications, 22.4% of the safety assessments were made by an employee of an additive manufacturer, 13.3% by an employee of a consulting firm selected by the manufacturer, and 64.3% by an expert panel selected by either a consulting firm or the manufacturer.

Some observational studies have shown that meat consumption is positively associated with weight gain, but intervention studies have shown mixed results. OBJECTIVE: Our objective was to assess the association between consumption of total meat, red meat, poultry, and processed meat and weight gain after 5 y of follow-up, on average, in the large European population who participated in the European Prospective Investigation into Cancer and Nutrition-Physical Activity, Nutrition, Alcohol, Cessation of Smoking, Eating Out of Home and Obesity (EPIC-PANACEA) project. DESIGN: A total of 103,455 men and 270,348 women aged 25-70 y were recruited between 1992 and 2000 in 10 European countries. Diet was assessed at baseline with the use of country-specific validated questionnaires. A dietary calibration study was conducted in a representative subsample of the cohort. Weight and height were measured at baseline and self-reported at follow-up in most centers. Associations between energy from meat (kcal/d) and annual weight change (g/y) were assessed with the use of linear mixed models, controlled for age, sex, total energy intake, physical activity, dietary patterns, and other potential confounders. RESULTS: Total meat consumption was positively associated with weight gain in men and women, in normal-weight and overweight subjects, and in smokers and nonsmokers. With adjustment for estimated energy intake, an increase in meat intake of 250 g/d (eg, one steak at approximately 450 kcal) would lead to a 2-kg higher weight gain after 5 y (95% CI: 1.5, 2.7 kg).

In addition, the excess risk per gram of intake is clearly higher than that of fresh red meat. Several hypotheses, which are mainly based on studies carried out on red meat, may explain why processed meat intake is linked to cancer risk. Those that have been tested experimentally are (i) that high-fat diets could promote carcinogenesis via insulin resistance or fecal bile acids; (ii) that cooking meat at a high temperature forms carcinogenic heterocyclic amines and polycyclic aromatic hydrocarbons; (iii) that carcinogenic N-nitroso compounds are formed in meat and endogenously; (iv) that heme iron in red meat can promote carcinogenesis because it increases cell proliferation in the mucosa, through lipoperoxidation and/or cytotoxicity of fecal water.

DESIGN Irreversibly unlinked and anonymised large scale survey of archived appendix samples. SETTING Archived appendix samples from the pathology departments of 41 UK hospitals participating in the earlier survey, and additional hospitals in regions with lower levels of participation in that survey. SAMPLE 32,441 archived appendix samples fixed in formalin and embedded in paraffin and tested for the presence of abnormal prion protein (PrP). RESULTS Of the 32,441 appendix samples 16 were positive for abnormal PrP, indicating an overall prevalence of 493 per million population (95% confidence interval 282 to 801 per million). The prevalence in those born in 1941-60 (733 per million, 269 to 1596 per million) did not differ significantly from those born between 1961 and 1985 (412 per million, 198 to 758 per million) and was similar in both sexes and across the three broad geographical areas sampled.

We aimed to investigate the links between BMI and the most common site-specific cancers. METHODS With primary care data from individuals in the Clinical Practice Research Datalink with BMI data, we fitted Cox models to investigate associations between BMI and 22 of the most common cancers, adjusting for potential confounders. We fitted linear then non-linear (spline) models; investigated effect modification by sex, menopausal status, smoking, and age; and calculated population effects. FINDINGS 5·24 million individuals were included; 166,955 developed cancers of interest. BMI was associated with 17 of 22 cancers, but effects varied substantially by site. Each 5 kg/m(2) increase in BMI was roughly linearly associated with cancers of the uterus (hazard ratio [HR] 1·62, 99% CI 1·56-1·69; p<0·0001), gallbladder (1·31, 1·12-1·52; p<0·0001), kidney (1·25, 1·17-1·33; p<0·0001), cervix (1·10, 1·03-1·17; p=0·00035), thyroid (1·09, 1·00-1·19; p=0·0088), and leukaemia (1·09, 1·05-1·13; p≤0·0001). BMI was positively associated with liver (1·19, 1·12-1·27), colon (1·10, 1·07-1·13), ovarian (1·09, 1.04-1.14), and postmenopausal breast cancers (1·05, 1·03-1·07) overall (all p<0·0001), but these effects varied by underlying BMI or individual-level characteristics. We estimated inverse associations with prostate and premenopausal breast cancer risk, both overall (prostate 0·98, 0·95-1·00; premenopausal breast cancer 0·89, 0·86-0·92) and in never-smokers (prostate 0·96, 0·93-0·99; premenopausal breast cancer 0·89, 0·85-0·94). By contrast, for lung and oral cavity cancer, we observed no association in never smokers (lung 0·99, 0·93-1·05; oral cavity 1·07, 0·91-1·26): inverse associations overall were driven by current smokers and ex-smokers, probably because of residual confounding by smoking amount. Assuming causality, 41% of uterine and 10% or more of gallbladder, kidney, liver, and colon cancers could be attributable to excess weight. We estimated that a 1 kg/m(2) population-wide increase in BMI would result in 3790 additional annual UK patients developing one of the ten cancers positively associated with BMI.

METHODS In the worldwide Adjuvant Tamoxifen: Longer Against Shorter (ATLAS) trial, 12,894 women with early breast cancer who had completed 5 years of treatment with tamoxifen were randomly allocated to continue tamoxifen to 10 years or stop at 5 years (open control). Allocation (1:1) was by central computer, using minimisation. After entry (between 1996 and 2005), yearly follow-up forms recorded any recurrence, second cancer, hospital admission, or death. We report effects on breast cancer outcomes among the 6846 women with ER-positive disease, and side-effects among all women (with positive, negative, or unknown ER status). Long-term follow-up still continues. This study is registered, number ISRCTN19652633. FINDINGS Among women with ER-positive disease, allocation to continue tamoxifen reduced the risk of breast cancer recurrence (617 recurrences in 3428 women allocated to continue vs 711 in 3418 controls, p=0·002), reduced breast cancer mortality (331 deaths vs 397 deaths, p=0·01), and reduced overall mortality (639 deaths vs 722 deaths, p=0·01).

The cumulative risk of recurrence during years 5–14 was 21·4% for women allocated to continue versus 25·1% for controls; breast cancer mortality during years 5–14 was 12·2% for women allocated to continue versus 15·0% for controls (absolute mortality reduction 2·8%). Treatment allocation seemed to have no effect on breast cancer outcome among 1248 women with ER-negative disease, and an intermediate effect among 4800 women with unknown ER status. Among all 12,894 women, mortality without recurrence from causes other than breast cancer was little affected (691 deaths without recurrence in 6454 women allocated to continue versus 679 deaths in 6440 controls; RR 0·99 [0·89–1·10]; p=0·84). For the incidence (hospitalisation or death) rates of specific diseases, RRs were as follows: pulmonary embolus 1·87 (95% CI 1·13–3·07, p=0·01 [including 0·2% mortality in both treatment groups]), stroke 1·06 (0·83–1·36), ischaemic heart disease 0·76 (0·60–0·95, p=0·02), and endometrial cancer 1·74 (1·30–2·34, p=0·0002). The cumulative risk of endometrial cancer during years 5–14 was 3·1% (mortality 0·4%) for women allocated to continue versus 1·6% (mortality 0·2%) for controls (absolute mortality increase 0·2%). INTERPRETATION For women with ER-positive disease, continuing tamoxifen to 10 years rather than stopping at 5 years produces a further reduction in recurrence and mortality, particularly after year 10. These results, taken together with results from previous trials of 5 years of tamoxifen treatment versus none, suggest that 10 years of tamoxifen treatment can approximately halve breast cancer mortality during the second decade after diagnosis.

By providing national and subnational assessments spanning the past 25 years, this study can inform debates on the importance of addressing risks in context. METHODS We used the comparative risk assessment framework developed for previous iterations of the Global Burden of Disease Study to estimate attributable deaths, disability-adjusted life-years (DALYs), and trends in exposure by age group, sex, year, and geography for 79 behavioural, environmental and occupational, and metabolic risks or clusters of risks from 1990 to 2015. This study included 388 risk-outcome pairs that met World Cancer Research Fund-defined criteria for convincing or probable evidence. We extracted relative risk and exposure estimates from randomised controlled trials, cohorts, pooled cohorts, household surveys, census data, satellite data, and other sources. We used statistical models to pool data, adjust for bias, and incorporate covariates. We developed a metric that allows comparisons of exposure across risk factors-the summary exposure value. Using the counterfactual scenario of theoretical minimum risk level, we estimated the portion of deaths and DALYs that could be attributed to a given risk. We decomposed trends in attributable burden into contributions from population growth, population age structure, risk exposure, and risk-deleted cause-specific DALY rates. We characterised risk exposure in relation to a Socio-demographic Index (SDI). FINDINGS Between 1990 and 2015, global exposure to unsafe sanitation, household air pollution, childhood underweight, childhood stunting, and smoking each decreased by more than 25%. Global exposure for several occupational risks, high body-mass index (BMI), and drug use increased by more than 25% over the same period. All risks jointly evaluated in 2015 accounted for 57·8% (95% CI 56·6-58·8) of global deaths and 41·2% (39·8-42·8) of DALYs. In 2015, the ten largest contributors to global DALYs among Level 3 risks were high systolic blood pressure (211·8 million [192·7 million to 231·1 million] global DALYs), smoking (148·6 million [134·2 million to 163·1 million]), high fasting plasma glucose (143·1 million [125·1 million to 163·5 million]), high BMI (120·1 million [83·8 million to 158·4 million]), childhood undernutrition (113·3 million [103·9 million to 123·4 million]), ambient particulate matter (103·1 million [90·8 million to 115·1 million]), high total cholesterol (88·7 million [74·6 million to 105·7 million]), household air pollution (85·6 million [66·7 million to 106·1 million]), alcohol use (85·0 million [77·2 million to 93·0 million]), and diets high in sodium (83·0 million [49·3 million to 127·5 million]). From 1990 to 2015, attributable DALYs declined for micronutrient deficiencies, childhood undernutrition, unsafe sanitation and water, and household air pollution; reductions in risk-deleted DALY rates rather than reductions in exposure drove these declines. Rising exposure contributed to notable increases in attributable DALYs from high BMI, high fasting plasma glucose, occupational carcinogens, and drug use. Environmental risks and childhood undernutrition declined steadily with SDI; low physical activity, high BMI, and high fasting plasma glucose increased with SDI. In 119 countries, metabolic risks, such as high BMI and fasting plasma glucose, contributed the most attributable DALYs in 2015. Regionally, smoking still ranked among the leading five risk factors for attributable DALYs in 109 countries; childhood underweight and unsafe sex remained primary drivers of early death and disability in much of sub-Saharan Africa. INTERPRETATION Declines in some key environmental risks have contributed to declines in critical infectious diseases. Some risks appear to be invariant to SDI. Increasing risks, including high BMI, high fasting plasma glucose, drug use, and some occupational exposures, contribute to rising burden from some conditions, but also provide opportunities for intervention. Some highly preventable risks, such as smoking, remain major causes of attributable DALYs, even as exposure is declining. Public policy makers need to pay attention to the risks that are increasingly major contributors to global burden.

In this study, we aimed to analyse the associations of blood pressure with 12 different presentations of cardiovascular disease. METHODS We used linked electronic health records from 1997 to 2010 in the CALIBER (CArdiovascular research using LInked Bespoke studies and Electronic health Records) programme to assemble a cohort of 1·25 million patients, 30 years of age or older and initially free from cardiovascular disease, a fifth of whom received blood pressure-lowering treatments. We studied the heterogeneity in the age-specific associations of clinically measured blood pressure with 12 acute and chronic cardiovascular diseases, and estimated the lifetime risks (up to 95 years of age) and cardiovascular disease-free life-years lost adjusted for other risk factors at index ages 30, 60, and 80 years. This study is registered at ClinicalTrials.gov, number NCT01164371. FINDINGS During 5·2 years median follow-up, we recorded 83,098 initial cardiovascular disease presentations. In each age group, the lowest risk for cardiovascular disease was in people with systolic blood pressure of 90-114 mm Hg and diastolic blood pressure of 60-74 mm Hg, with no evidence of a J-shaped increased risk at lower blood pressures. The effect of high blood pressure varied by cardiovascular disease endpoint, from strongly positive to no effect. Associations with high systolic blood pressure were strongest for intracerebral haemorrhage (hazard ratio 1·44 [95% CI 1·32-1·58]), subarachnoid haemorrhage (1·43 [1·25-1·63]), and stable angina (1·41 [1·36-1·46]), and weakest for abdominal aortic aneurysm (1·08 [1·00-1·17]). Compared with diastolic blood pressure, raised systolic blood pressure had a greater effect on angina, myocardial infarction, and peripheral arterial disease, whereas raised diastolic blood pressure had a greater effect on abdominal aortic aneurysm than did raised systolic pressure. Pulse pressure associations were inverse for abdominal aortic aneurysm (HR per 10 mm Hg 0·91 [95% CI 0·86-0·98]) and strongest for peripheral arterial disease (1·23 [1·20-1·27]). People with hypertension (blood pressure ≥140/90 mm Hg or those receiving blood pressure-lowering drugs) had a lifetime risk of overall cardiovascular disease at 30 years of age of 63·3% (95% CI 62·9-63·8) compared with 46·1% (45·5-46·8) for those with normal blood pressure, and developed cardiovascular disease 5·0 years earlier (95% CI 4·8-5·2). Stable and unstable angina accounted for most (43%) of the cardiovascular disease-free years of life lost associated with hypertension from index age 30 years, whereas heart failure and stable angina accounted for the largest proportion (19% each) of years of life lost from index age 80 years. INTERPRETATION The widely held assumptions that blood pressure has strong associations with the occurrence of all cardiovascular diseases across a wide age range, and that diastolic and systolic associations are concordant, are not supported by the findings of this high-resolution study. Despite modern treatments, the lifetime burden of hypertension is substantial. These findings emphasise the need for new blood pressure-lowering strategies, and will help to inform the design of randomised trials to assess them.

Prevention efforts might reduce HIV incidence but are unlikely to eliminate this disease. We investigated a theoretical strategy of universal voluntary HIV testing and immediate treatment with ART, and examined the conditions under which the HIV epidemic could be driven towards elimination. METHODS We used mathematical models to explore the effect on the case reproduction number (stochastic model) and long-term dynamics of the HIV epidemic (deterministic transmission model) of testing all people in our test-case community (aged 15 years and older) for HIV every year and starting people on ART immediately after they are diagnosed HIV positive. We used data from South Africa as the test case for a generalised epidemic, and assumed that all HIV transmission was heterosexual. FINDINGS The studied strategy could greatly accelerate the transition from the present endemic phase, in which most adults living with HIV are not receiving ART, to an elimination phase, in which most are on ART, within 5 years. It could reduce HIV incidence and mortality to less than one case per 1000 people per year by 2016, or within 10 years of full implementation of the strategy, and reduce the prevalence of HIV to less than 1% within 50 years. We estimate that in 2032, the yearly cost of the present strategy and the theoretical strategy would both be US$1.7 billion; however, after this time, the cost of the present strategy would continue to increase whereas that of the theoretical strategy would decrease.

DESIGN Analysis of the representativeness of the respondents to the GP Patient Survey compared with those who were sampled (5.5 million patients registered with 8273 general practices in England in January 2009) and with the general population. Analysis of non-response bias looked at the relation between practice response rates and scores on the survey. Analysis of the reliability of the survey estimated the proportion of the variance of practice scores attributable to true differences between practices. RESULTS The overall response rate was 38.2% (2.2 million responses), which is comparable to that in surveys using similar methodology in the UK. Men, young adults, and people living in deprived areas were under-represented among respondents. However, for questions related to pay for performance, there was no systematic association between response rates and questionnaire scores. Two questions which triggered payments to general practitioners were reliable measures of practice performance, with average practice-level reliability coefficients of 93.2% and 95.0%. Less than 3% and 0.5% of practices had fewer than the number of responses required to achieve conventional reliability levels of 90% and 70%. A change to the payment formula in 2009 resulted in an increase in the average impact of random variation in patient scores on payments to general practitioners compared with payments made in 2007 and 2008. CONCLUSIONS There is little evidence to support the concern of some general practitioners that low response rates and selective non-response bias have led to systematic unfairness in payments attached to questionnaire scores.

Cancer prevalence for 2012 and beyond was estimated using the Prevalence Incidence Approach Model, assuming constant future incidence and survival trends but dynamic projections of the U.S. population.

METHODS We conducted a retrospective case note review of all current paediatric kidney transplant patients in the UK, with data collected at 6 months, 1, 2 and 5 years following transplantation in subjects with hypertension (systolic and/or diastolic BP > 95th > ) and non-hypertensive subjects BP ≤ 95th > . RESULTS In total, 27.3% (117/428), 27.6% (118/428), 26.0% (95/365) and 25.6% (50/195) of the patients were hypertensive (systolic and/or diastolic BP > 95th > ) at 6 months, 1, 2 and 5 years following transplantation, respectively. A total of 58.4% of the patients at 6 months, 52.8% at 1 year, 48.2% at 2 years and 48.2% at 5 years were receiving anti-hypertensive therapy, of whom 31.6-36.6% remained hypertensive. When subjects were identified as being hypertensive, on anti-hypertensive medication or had untreated hypertension (systolic and/or diastolic BP > 95th > ), 66.4, 61.0, 56.4 and 55.9% of patients were hypertensive at 6 months, 1, 2 and 5 years, respectively.

Both autologous and allogeneic MSC therapies are possible; however, their safety and efficacy have not been compared. OBJECTIVE To test whether allogeneic MSCs are as safe and effective as autologous MSCs in patients with left ventricular (LV) dysfunction due to ICM. DESIGN, SETTING, AND PATIENTS A phase 1/2 randomized comparison (POSEIDON study) in a US tertiary-care referral hospital of allogeneic and autologous MSCs in 30 patients with LV dysfunction due to ICM between April 2, 2010, and September 14, 2011, with 13-month follow-up. INTERVENTION Twenty million, 100 million, or 200 million cells (5 patients in each cell type per dose level) were delivered by transendocardial stem cell injection into 10 LV sites. MAIN OUTCOME MEASURES Thirty-day postcatheterization incidence of predefined treatment-emergent serious adverse events (SAEs). Efficacy assessments included 6-minute walk test, exercise peak VO2, Minnesota Living with Heart Failure Questionnaire (MLHFQ), New York Heart Association class, LV volumes, ejection fraction (EF), early enhancement defect (EED; infarct size), and sphericity index. RESULTS Within 30 days, 1 patient in each group (treatment-emergent SAE rate, 6.7%) was hospitalized for heart failure, less than the prespecified stopping event rate of 25%. The 1-year incidence of SAEs was 33.3% (n = 5) in the allogeneic group and 53.3% (n = 8) in the autologous group (P = .46). At 1 year, there were no ventricular arrhythmia SAEs observed among allogeneic recipients compared with 4 patients (26.7%) in the autologous group (P = .10). Relative to baseline, autologous but not allogeneic MSC therapy was associated with an improvement in the 6-minute walk test and the MLHFQ score, but neither improved exercise VO2 max. Allogeneic and autologous MSCs reduced mean EED by −33.21% (95% CI, −43.61% to −22.81%; P < .001) and sphericity index but did not increase EF. Allogeneic MSCs reduced LV end-diastolic volumes. Low-dose concentration MSCs (20 million cells) produced greatest reductions in LV volumes and increased EF. Allogeneic MSCs did not stimulate significant donor-specific alloimmune reactions. CONCLUSIONS In this early-stage study of patients with ICM, transendocardial injection of allogeneic and autologous MSCs without a placebo control were both associated with low rates of treatment-emergent SAEs, including immunologic reactions.

We designed FOCUS2 to investigate reduced-dose chemotherapy options and to seek objective predictors of outcome in frail patients with advanced colorectal cancer. METHODS We undertook an open, 2 × 2 factorial trial in 61 UK centres for patients with previously untreated advanced colorectal cancer who were considered unfit for full-dose chemotherapy. After comprehensive health assessment (CHA), patients were randomly assigned by minimisation to: 48-h intravenous fluorouracil with levofolinate (group A); oxaliplatin and fluorouracil (group B); capecitabine (group C); or oxaliplatin and capecitabine (group D). Treatment allocation was not masked. Starting doses were 80% of standard doses, with discretionary escalation to full dose after 6 weeks. The two primary outcome measures were: addition of oxaliplatin ([A vs B] + [C vs D]), assessed with progression-free survival (PFS); and substitution of fluorouracil with capecitabine ([A vs C] + [B vs D]), assessed by change from baseline to 12 weeks in global quality of life (QoL). Analysis was by intention to treat. Baseline clinical and CHA data were modelled against outcomes with a novel composite measure, overall treatment utility (OTU). This study is registered, number ISRCTN21221452. FINDINGS 459 patients were randomly assigned (115 to each of groups A-C, 114 to group D). Factorial comparison of addition of oxaliplatin versus no addition suggested some improvement in PFS, but the finding was not significant (median 5·8 months [IQR 3·3-7·5] vs 4·5 months [2·8-6·4]; hazard ratio 0·84, 95% CI 0·69-1·01, p=0·07). Replacement of fluorouracil with capecitabine did not improve global QoL: 69 of 124 (56%) patients receiving fluorouracil reported improvement in global QoL compared with 69 of 123 (56%) receiving capecitabine. The risk of having any grade 3 or worse toxic effect was not significantly increased with oxaliplatin (83/219 [38%] vs 70/221 [32%]; p=0·17), but was higher with capecitabine than with fluorouracil (88/222 [40%] vs 65/218 [30%]; p=0·03). In multivariable analysis, fewer baseline symptoms (odds ratio 1·32, 95% CI 1·14-1·52), less widespread disease (1·51, 1·05-2·19), and use of oxaliplatin (0·57, 0·39-0·82) were predictive of better OTU. INTERPRETATION FOCUS2 shows that with an appropriate design, including reduced starting doses of chemotherapy, frail and elderly patients can participate in a randomised controlled trial. On balance, a combination including oxaliplatin was preferable to single-agent fluoropyrimidines, although the primary endpoint of PFS was not met. Capecitabine did not improve QoL compared with fluorouracil. Comprehensive baseline assessment holds promise as an objective predictor of treatment benefit.

Interleukin-6 receptor (IL6R) signalling propagates downstream inflammation cascades. To assess whether this pathway is causally relevant to coronary heart disease, we studied a functional genetic variant known to affect IL6R signalling. METHODS In a collaborative meta-analysis, we studied Asp358Ala (rs2228145) in IL6R in relation to a panel of conventional risk factors and inflammation biomarkers in 125,222 participants. We also compared the frequency of Asp358Ala in 51,441 patients with coronary heart disease and in 136,226 controls. To gain insight into possible mechanisms, we assessed Asp358Ala in relation to localised gene expression and to postlipopolysaccharide stimulation of interleukin 6. FINDINGS The minor allele frequency of Asp358Ala was 39%. Asp358Ala was not associated with lipid concentrations, blood pressure, adiposity, dysglycaemia, or smoking (p value for association per minor allele ≥0·04 for each). By contrast, for every copy of 358Ala inherited, mean concentration of IL6R increased by 34·3% (95% CI 30·4-38·2) and of interleukin 6 by 14·6% (10·7-18·4), and mean concentration of C-reactive protein was reduced by 7·5% (5·9-9·1) and of fibrinogen by 1·0% (0·7-1·3).

METHODS In this outcome-blinded, randomised controlled trial, 2518 patients who were admitted to hospital within 1 week of an acute stroke and who were immobile were enrolled from 64 centres in the UK, Italy, and Australia. Patients were allocated via a central randomisation system to routine care plus thigh-length GCS (n=1256) or to routine care plus avoidance of GCS (n=1262). A technician who was blinded to treatment allocation undertook compression Doppler ultrasound of both legs at about 7-10 days and, when practical, again at 25-30 days after enrolment.

We aimed to estimate the incidence of admissions and deaths for such infections in children younger than 5 years in 2010. METHODS We estimated the incidence of admissions for severe and very severe ALRI in children younger than 5 years, stratified by age and region, with data from a systematic review of studies published between Jan 1, 1990, and March 31, 2012, and from 28 unpublished population-based studies. We applied these incidence estimates to population estimates for 2010, to calculate the global and regional burden in children admitted with severe ALRI in that year. We estimated in-hospital mortality due to severe and very severe ALRI by combining incidence estimates with case fatality ratios from hospital-based studies. FINDINGS We identified 89 eligible studies and estimated that in 2010, 11·9 million (95% CI 10·3-13·9 million) episodes of severe and 3·0 million (2·1-4·2 million) episodes of very severe ALRI resulted in hospital admissions in young children worldwide. Incidence was higher in boys than in girls, the sex disparity being greatest in South Asian studies. On the basis of data from 37 hospital studies reporting case fatality ratios for severe ALRI, we estimated that roughly 265,000 (95% CI 160,000-450,000) in-hospital deaths took place in young children, with 99% of these deaths in developing countries. Therefore, the data suggest that although 62% of children with severe ALRI are treated in hospitals, 81% of deaths happen outside hospitals. INTERPRETATION Severe ALRI is a substantial burden on health services worldwide and a major cause of hospital referral and admission in young children. Improved hospital access and reduced inequities, such as those related to sex and rural status, could substantially decrease mortality related to such infection.

The results of the UK Age trial, which compared the effect of invitation to annual mammographic screening from age 40 years with commencement of screening at age 50 years on breast cancer mortality, have been reported at 10 years of follow-up and showed no significant difference in mortality between the trial groups. Here, we report the results of the UK Age trial after 17 years of follow-up. METHODS Women aged 39-41 from 23 UK NHS Breast Screening Programme units years were randomly assigned by individual randomisation (1:2) to either an intervention group offered annual screening by mammography up to and including the calendar year of their 48th birthday or to a control group receiving usual medical care (invited for screening at age 50 years and every 3 years thereafter). Both groups were stratified by general practice. We compared breast cancer incidence and mortality by time since randomisation. Analyses included all women randomly assigned who could be traced with the National Health Service Central Register and who had not died or emigrated before entry. The primary outcome measures were mortality from breast cancer (defined as deaths with breast cancer coded as the underlying cause of death) and breast cancer incidence, including in-situ, invasive, and total incidence. Because there is an interest in the timing of the mortality effect, we analysed the results in different follow-up periods. This trial is registered, number ISRCTN24647151. FINDINGS Between Oct 14, 1990, and Sept 25, 1997, 160 921 participants were randomly assigned; 53 883 women in the intervention group and 106 953 assigned to usual medical care were included in this analysis. After a median follow-up of 17 years (IQR 16·8-18·8), the rate ratio (RR) for breast cancer mortality was 0·88 (95% CI 0·74-1·04) from tumours diagnosed during the intervention phase. A significant reduction in breast cancer mortality was noted in the intervention group compared with the control group in the first 10 years after diagnosis (RR 0·75, 0·58-0·97) but not thereafter (RR 1·02, 0·80-1·30) from tumours diagnosed during the intervention phase. The overall breast cancer incidence during 17 year follow-up was similar between the intervention group and the control group (RR 0·98, 0·93-1·04). INTERPRETATION Our results support an early reduction in mortality from breast cancer with annual mammography screening in women aged 40-49 years. Further data are needed to fully understand long-term effects. Cumulative incidence figures suggest at worst a small amount of overdiagnosis.

The objective of this study was to evaluate the external validity of published cost-effectiveness studies by comparing the data used in these studies (typically based on RCTs) to observational data from actual clinical practice. Selective Cox-2 inhibitors (coxibs) were used as an example. METHODS AND FINDINGS The UK General Practice Research Database (GPRD) was used to estimate the exposure characteristics and individual probabilities of upper gastrointestinal (GI) events during current exposure to nonsteroidal anti-inflammatory drugs (NSAIDs) or coxibs. A basic cost-effectiveness model was developed evaluating two alternative strategies: prescription of a conventional NSAID or coxib. Outcomes included upper GI events as recorded in GPRD and hospitalisation for upper GI events recorded in the national registry of hospitalisations (Hospital Episode Statistics) linked to GPRD. Prescription costs were based on the prescribed number of tables as recorded in GPRD and the 2006 cost data from the British National Formulary. The study population included over 1 million patients prescribed conventional NSAIDs or coxibs. Only a minority of patients used the drugs long-term and daily (34.5% of conventional NSAIDs and 44.2% of coxibs), whereas coxib RCTs required daily use for at least 6-9 months. The mean cost of preventing one upper GI event as recorded in GPRD was US$104k (ranging from US$64k with long-term daily use to US$182k with intermittent use) and US$298k for hospitalizations. The mean costs (for GPRD events) over calendar time were US$58k during 1990-1993 and US$174k during 2002-2005. Using RCT data rather than GPRD data for event probabilities, the mean cost was US$16k with the VIGOR RCT and US$20k with the CLASS RCT. CONCLUSIONS The published cost-effectiveness analyses of coxibs lacked external validity, did not represent patients in actual clinical practice, and should not have been used to inform prescribing policies.

Although most prion strains invade the CNS, some prion strains cannot gain entry and do not cause clinical signs of disease. The conformational basis for this remarkable variation in the pathogenesis among strains is unclear. Using mouse-adapted prion strains, here we show that highly neuroinvasive prion strains primarily form diffuse aggregates in brain and are noncongophilic, conformationally unstable in denaturing conditions, and lead to rapidly lethal disease. These neuroinvasive strains efficiently generate PrP(Sc) over short incubation periods. In contrast, the weakly neuroinvasive prion strains form large fibrillary plaques and are stable, congophilic, and inefficiently generate PrP(Sc) over long incubation periods. Overall, these results indicate that the most neuroinvasive prion strains are also the least stable, and support the concept that the efficient replication and unstable nature of the most rapidly converting prions may be a feature linked to their efficient spread into the CNS.", "title": "Biochemical Properties of Highly Neuroinvasive Prion Strains" }, { "docid": "41650417", "text": "PURPOSE To evaluate the effect of KRAS and epidermal growth factor receptor (EGFR) genotype on the response to erlotinib treatment in the BR.21, placebo-controlled trial.

We reanalyzed EGFR deletion/mutation using two highly sensitive techniques that detect abnormalities in samples with 5% to 10% tumor cellularity. KRAS mutation was analyzed by direct sequencing. RESULTS Thirty patients (15%) had KRAS mutations, 34 (17%) had EGFR exon 19 deletion or exon 21 L858R mutations, and 61 (38%) had high EGFR gene copy (FISH positive). Response rates were 10% for wild-type and 5% for mutant KRAS (P = .69), 7% for wild-type and 27% for mutant EGFR (P = .03), and 5% for EGFR FISH-negative and 21% for FISH-positive patients (P = .02). Significant survival benefit from erlotinib therapy was observed for patients with wild-type KRAS (hazard ratio [HR] = 0.69, P = .03) and EGFR FISH positivity (HR = 0.43, P = .004) but not for patients with mutant KRAS (HR = 1.67, P = .31), wild-type EGFR (HR = 0.74, P = .09), mutant EGFR (HR = 0.55, P = .12), and EGFR FISH negativity (HR = 0.80, P = .35). In multivariate analysis, only EGFR FISH-positive status was prognostic for poorer survival (P = .025) and predictive of differential survival benefit from erlotinib (P = .005).

We undertook the third National Survey of Sexual Attitudes and Lifestyles (Natsal-3) after implementation of national sexual health strategies, and describe the epidemiology of four STIs in Britain (England, Scotland, and Wales) and the uptake of interventions. METHODS Between Sept 6, 2010 and Aug 31, 2012 , we did a probability sample survey of 15,162 women and men aged 16-74 years in Britain. Participants were interviewed with computer-assisted face-to-face and self-completion questionnaires. Urine from a sample of participants aged 16-44 years who reported at least one sexual partner over the lifetime was tested for the presence of Chlamydia trachomatis, type-specific human papillomavirus (HPV), Neisseria gonorrhoeae, and HIV antibody. We describe age-specific and sex-specific prevalences of infection and intervention uptake, in relation to demographic and behavioural factors, and explore changes since Natsal-1 (1990-91) and Natsal-2 (1999-2001). FINDINGS Of 8047 eligible participants invited to provide a urine sample, 4828 (60%) agreed. We excluded 278 samples, leaving 4550 (94%) participants with STI test results. Chlamydia prevalence was 1·5% (95% CI 1·1-2·0) in women and 1·1% (0·7-1·6) in men. Prevalences in individuals aged 16-24 years were 3·1% (2·2-4·3) in women and 2·3% (1·5-3·4) in men. Area-level deprivation and higher numbers of partners, especially without use of condoms, were risk factors. However, 60·4% (45·5-73·7) of chlamydia in women and 43·3% (25·9-62·5) in men was in individuals who had had one partner in the past year. Among sexually active 16-24-year-olds, 54·2% (51·4-56·9) of women and 34·6% (31·8-37·4) of men reported testing for chlamydia in the past year, with testing higher in those with more partners. High-risk HPV was detected in 15·9% (14·4-17·5) of women, similar to in Natsal-2. Coverage of HPV catch-up vaccination was 61·5% (58·2-64·7). Prevalence of HPV types 16 and 18 in women aged 18-20 years was lower in Natsal-3 than Natsal-2 (5·8% [3·9-8·6] vs 11·3% [6·8-18·2]; age-adjusted odds ratio 0·44 [0·21-0·94]). Gonorrhoea (<0·1% prevalence in women and men) and HIV (0·1% prevalence in women and 0·2% in men) were uncommon and restricted to participants with recognised high-risk factors. Since Natsal-2, substantial increases were noted in attendance at sexual health clinics (from 6·7% to 21·4% in women and from 7·7% to 19·6% in men) and HIV testing (from 8·7% to 27·6% in women and from 9·2% to 16·9% in men) in the past 5 years. INTERPRETATION STIs were distributed heterogeneously, requiring general and infection-specific interventions. Increases in testing and attendance at sexual health clinics, especially in people at highest risk, are encouraging.

Methods Cox proportional hazards models in the derivation cohort to derive separate risk equations in men and women for evaluation at 10 years. Risk factors considered included those already in QRISK2 (age, ethnicity, deprivation, systolic blood pressure, body mass index, total cholesterol: high density lipoprotein cholesterol ratio, smoking, family history of coronary heart disease in a first degree relative aged less than 60 years, type 1 diabetes, type 2 diabetes, treated hypertension, rheumatoid arthritis, atrial fibrillation, chronic kidney disease (stage 4 or 5)) and new risk factors (chronic kidney disease (stage 3, 4, or 5), a measure of systolic blood pressure variability (standard deviation of repeated measures), migraine, corticosteroids, systemic lupus erythematosus (SLE), atypical antipsychotics, severe mental illness, and HIV/AIDs).

Thus when opening a short position, the asks offer nothing to the process except competition for your order getting filled. Part of managing the trade is the interest rate risk. If the asks are as illiquid as detailed in the question, it may be difficult even to locate the shares for borrowing.

The ask prices represent people who are trying to sell shares, and the bid prices represent people who are trying to buy shares. Using your example, you could put in a limit order to short (sell) 1000 shares at $3.01, meaning that your order would become the ask price at $3.01. There is an ask price ahead of you for 500 shares at $3.00. So people would have to buy those 500 shares at $3.00 before anyone could buy your 1000 shares at $3.01. But it's possible that your order to sell 1000 shares at $3.01 never gets filled, if the buyers don't buy all the shares ahead of you. The price could drop to $1.00 without hitting $3.01 and you will have missed out on the trade. If you really wanted to short 1000 shares, you could use a market order. Let's say there's a bid for 750 shares at $2.50, and another bid for 250 shares at $2.49. If you entered a market order to sell 1000 shares, your order would get filled at the best bid prices, so first you would sell 750 shares at $2.50 and then you would sell 250 shares at $2.49. I was just using your example to explain things. In reality there won't be such a wide spread between the bid and ask prices. A stock might have a bid price of $10.50 and an ask price of $10.51, so there would only be a 1 cent difference between putting in a limit order to sell 1000 shares at $10.51 and just using a market order to sell 1000 shares and getting them filled at $10.50. Also, your example probably wouldn't work in real life, because brokers typically don't allow people to short stocks that are trading under $5 per share. As for your question about how often you are unable to make a short sale, it can sometimes happen with stocks that are heavily shorted and your broker may not be able to find any more shares to borrow.

[ { "docid": "28604", "text": "\"The current stock price you're referring to is actually the price of the last trade. It is a historical price – but during market hours, that's usually mere seconds ago for very liquid stocks. Whereas, the bid and ask are the best potential prices that buyers and sellers are willing to transact at: the bid for the buying side, and the ask for the selling side. But, think of the bid and ask prices you see as \"\"tip of the iceberg\"\" prices. That is: The \"\"Bid: 13.20 x200\"\" is an indication that there are potential buyers bidding $13.20 for up to 200 shares. Their bids are the highest currently bid; and there are others in line behind with lower bid prices. So the \"\"bid\"\" you're seeing is actually the best bid price at that moment. If you entered a \"\"market\"\" order to sell more than 200 shares, part of your order would likely be filled at a lower price. The \"\"Ask: 13.27 x1,000\"\" is an indication that there are potential sellers asking $13.27 for up to 1000 shares. Their ask prices are the lowest currently asked; and there are others in line behind with higher ask prices. So the \"\"ask\"\" you're seeing is the best asking price at that moment. If you entered a \"\"market\"\" order to buy more than 1000 shares, part of your order would likely be filled at a higher price. A transaction takes place when either a potential buyer is willing to pay the asking price, or a potential seller is willing to accept the bid price, or else they meet in the middle if both buyers and sellers change their orders. Note: There are primarily two kinds of stock exchanges. The one I just described is a typical order-driven matched bargain market, and perhaps the kind you're referring to. The other kind is a quote-driven over-the-counter market where there is a market-maker, as JohnFx already mentioned. In those cases, the spread between the bid & ask goes to the market maker as compensation for making a market in a stock. For a liquid stock that is easy for the market maker to turn around and buy/sell to somebody else, the spread is small (narrow). For illiquid stocks that are harder to deal in, the spread is larger (wide) to compensate the market-maker having to potentially carry the stock in inventory for some period of time, during which there's a risk to him if it moves in the wrong direction. Finally ... if you wanted to buy 1000 shares, you could enter a market order, in which case as described above you'll pay $13.27. If you wanted to buy your shares at no more than $13.22 instead, i.e. the so-called \"\"current\"\" price, then you would enter a limit order for 1000 shares at $13.22. And more to the point, your order would become the new highest-bid price (until somebody else accepts your bid for their shares.)

They have access to market data using Level II terminals, which show them all of the prices (buy and sell) for a given stock. Every publicly traded stock (at least in the U.S.) relies on firms called \"\"market makers\"\". Market makers are the ones who ultimately actually buy and sell the shares of companies, making their money on the difference between what they bought the stock at and what they can sell it for. Sometimes those margins can be in hundreds of a cent per share, but if you trade enough shares...well, it adds up. The most widely traded stocks (Apple, Microsoft, BP, etc) may have hundreds of market makers who are willing to handle share trades. Each market maker sets their own price on what they'll pay (the \"\"bid\"\") to buy someone's stock who wants to sell and what they'll sell (the \"\"ask\"\") that share for to someone who wants to buy it. When a market maker wants to be competitive, he may price his bid/ask pretty aggressively, because automated trading systems are designed to seek out the best bid/ask prices for their trade executions. As such, you might get a huge chunk of market makers in a popular stock to all set their prices almost identically to one another. Other market makers who aren't as enthusiastic will set less competitive prices, so they don't get much (maybe no) business. In any case, what you see when you pull up a stock quote is called the \"\"best bid/ask\"\" price. In other words, you're seeing the highest price a market maker will pay to buy that stock, and the lowest price that a market maker will sell that stock. You may get a best bid from one market maker and a best ask from a different one. In any case, consumers must be given best bid/ask prices. Market makers actually control the prices of shares. They can see what's out there in terms of what people want to buy or sell, and they modify their prices accordingly. If they see a bunch of sell orders coming into the system, they'll start dropping prices, and if people are in a buying mood then they'll raise prices. Market makers can actually ignore requests for trades (whether buy or sell) if they choose to, and sometimes they do, which is why a limit order (a request to buy/sell a stock at a specific price, regardless of its current actual price) that someone places may go unfilled and die at the end of the trading session. No market maker is willing to fill the order. Nowadays, these systems are largely automated, so they operate according to complex rules defined by their owners. Very few trades actually involve human intervention, because people can't digest the information at a fast enough pace to keep up with automated platforms.

Basically the full service can provide you with advice in the form of recommendations on what to buy and sell and when, you call them up when you want to put an order in and the commissions are usually higher. Whilst an online broker usually doesn't provide advice (unless you ask for it at a specified fee), you place your orders online through the brokers website or trading platform and the commissions are usually much lower. The best thing to do when starting off is to go to your country's stock exchange, for example, The ASX in Sydney Australia, and they should have a list of available brokers. Some of the online brokers may have a practice or simulation account you can practice on, and they usually provide good educational material to help you get started. If you went with an online broker and wanted to buy Facebook on the secondary market (that is on the stock exchange after the IPO closes), you would log onto your brokers website or platform and go to the orders section. You would place a new order to buy say 100 Facebook shares at a certain price. You can use a market order, meaning the order will be immediately executed at the current market price and you will own the shares, or a limit price order where you select a price below the current market price and wait for the price to come down and hit your limit price before your order is executed and you get your shares. There are other types of orders available with different brokers which you will learn about when you log onto their website. You also need to be careful that you have the funds available to pay for the share at settlement, which is 3 business days after your order was executed. Some brokers may require you to have the funds deposited into an account which is linked to your trading account with them. To sell your shares you do the same thing, except this time you choose a sell order instead of a buy order. It becomes quite simple once you have done it a couple of times. The best thing is to do some research and get started. Good Luck.", "title": "" }, { "docid": "285126", "text": "\"I may be underestimating your knowledge of how exchanges work; if so, I apologize. If not, then I believe the answer is relatively straightforward. Lets say price of a stock at time t1 is 15$ . There are many types of price that an exchange reports to the public (as discussed below); let's say that you're referring to the most recent trade price. That is, the last time a trade executed between a willing buyer and a willing seller was at $15.00. Lets say a significant buy order of 1M shares came in to the market. Here I believe might be a misunderstanding on your part. I think you're assuming that the buy order must necessarily be requesting a price of $15.00 because that was the last published price at time t1. In fact, orders can request any price they want. It's totally okay for someone to request to buy at $10.00. Presumably nobody will want to sell to him, but it's still a perfectly valid buy order. But let's continue under the assumptions that at t1: This makes the bid $14.99 and the ask $15.00. (NYSE also publishes these prices.) There aren't enough people selling that stock. It's quite rare (in major US equities) for anyone to place a buy order that exceeds the total available shares listed for sale at all prices. What I think you mean is that 1M is larger than the amount of currently-listed sell requests at the ask of $15.00. So say of the 1M only 100,000 had a matching sell order and others are waiting. So this means that there were exactly 100,000 shares waiting to be sold at the ask of $15.00, and that all other sellers currently in the market told NYSE they were only willing to sell for a price of $15.01 or higher. If there had been more shares available at $15.00, then NYSE would have matched them. This would be a trigger to the automated system to start increasing the price. Here is another point of misunderstanding, I think. NYSE's automated system does not invent a new, higher price to publish at this point. Instead it simply reports the last trade price (still $15.00), and now that all of the willing sellers at $15.00 have been matched, NYSE also publishes the new ask price of $15.01. It's not that NYSE has decided $15.01 is the new price for the stock; it's that $15.01 is now the lowest price at which anyone (known to NYSE) is willing to sell. If nobody happened to be interested in selling at $15.01 at t1, but there were people interested in selling at $15.02, then the new published ask would be $15.02 instead of $15.01 -- not because NYSE decided it, but just because those happened to be the facts at the time. Similarly, the new bid is most likely now $15.00, assuming the person who placed the order for 1M shares did not cancel the remaining unmatched 900,000 shares of his/her order. That is, $15.00 is now the highest price at which anyone (known to NYSE) is willing to buy. How much time does the automated system wait to increment the price, the frequency of the price change and by what percentage to increment etc. So I think the answer to all these questions is that the automated system does none of these things. It merely publishes information about (a) the last trade price, (b) the price that is currently the lowest price at which anyone has expressed a willingness to sell, and (c) the price that is currently the highest price at which anyone has expressed a willingness to buy. ::edit:: Oh, I forgot to answer your primary question. Can we estimate the impact of a large buy order on the share price? Not only can we estimate the impact, but we can know it explicitly. Because the exchange publishes information on all the orders it knows about, anyone tracking that information can deduce that (in this example) there were exactly 100,000 shares waiting to be purchased at $15.00. So if a \"\"large buy order\"\" of 1M shares comes in at $15.00, then we know that all of the people waiting to sell at $15.00 will be matched, and the new lowest ask price will be $15.01 (or whatever was the next lowest sell price that the exchange had previously published).\"", "title": "" }, { "docid": "87065", "text": "The Bid price is simply the highest buy price currently being offered and the Ask price simply the lowest sell price being offered.

A market order is an order to buy or sell a stock at the current market price. A limit order is an order to buy or sell a security at a specific price.

If you place an order for 100 shares, the sellers willing to sell 100 shares at the lowest price will be matched with your order (sometimes you may get 50 shares at one price and 50 shares at a slightly different price). If your stock has a lot of volatility and you place a market order for a small amount of shares, you will get the best price. If you place a limit order, you specify the price at which you want to buy shares.

The spot price is what the last guy paid to buy a barrel of oil right now (and thus a pretty good indicator of what you'll have to pay). The futures price is what the last guy paid for a \"\"futures contract\"\", where they agreed to buy a barrel of oil for $X at some point in the future. Futures contracts are a form of hedging; a futures contract is usually sold at a price somewhere between the current spot price and the true expected future spot price; the buyer saves money versus paying the spot price, while the seller still makes a profit. But, the buyer of a futures contract is basically betting that the spot price as of delivery will be higher, while the seller is betting it will be lower. Futures contracts are available for a wide variety of acceptable future dates, and form a curve when plotted on a graph that will trend in one direction or the other. Now, as Chad said, oil companies basically get their cut no matter what. Oil stocks are generally a good long-term bet. As far as the best short-term time to buy in to an oil stock, look for very short windows when the spot and near-future price of gasoline is trending downward but oil is still on the uptick. During those times, the oil companies are paying their existing (high) contracts for oil, but when the spot price is low it affects futures prices, which will affect the oil companies' margins. Day traders will see that, squawk \"\"the sky is falling\"\" and sell off, driving the price down temporarily. That's when you buy in. Pretty much the only other time an oil stock is a guaranteed win is when the entire market takes a swan dive and then bottoms out. Oil has such a built-in demand, for the foreseeable future, that regardless of how bad it gets you WILL make money on an oil stock. So, when the entire market's in a panic and everyone's heading for gold, T-debt etc, buy the major oil stocks across the spectrum. Even if one stock tanks, chances are really good that another company will see that and offer a buyout, jacking the bought company's stock (which you then sell and reinvest the cash into the buying company, which will have taken a hit on the news due to the huge drop in working capital). Of course, the one thing to watch for in the headlines is any news that renewables have become much more attractive than oil. You wait; in the next few decades some enterprising individual will invent a super-efficient solar cell that provides all the power a real, practical car will ever need, and that is simultaneously integrated into wind farms making oil/gas plants passe.

The new uptick rule triggers a ban on short selling when the stock drops a certain amount. The SEC defines the process like this: The \"\"circuit breaker\"\" is triggered for a security any day the price declines by 10% or more from the prior day's closing price The alternative uptick rule, which permits short selling only \"\"if the price of the security is above the current national best bid.\"\"1 The rule applies \"\"to short sale orders in that security for the remainder of the day as well as the following day.\"\" In general, the rule applies to all equities. 1) The national best bid is usually the bid price that you see in Level 1 data. Example: If a stock closed at $100/share on Monday, the \"\"circuit breaker\"\" would be triggered if the stock traded at or below $90/share during Tuesday's session. Short-selling would be disallowed until the start of trading on Thursday unless the short-sell price is above the national best bid, i.e. on an uptick. Purpose: The stated purpose of this rule is promote market stability and preserve investor confidence by restricting potentially abusive short selling from driving prices farther downward during periods of increased volatility and downward price pressure. Whether or not such rules succeed is a matter of some debate, and the SEC removed similar uptick rules in 2006 because \"\"they modestly reduce liquidity and do not appear necessary to prevent manipulation.\"\" Exceptions: There are a few exceptions to the uptick rule that mainly revolve around when the short sell order was placed or when the securities will be delivered.\"", "title": "" }, { "docid": "507357", "text": "Many of the Bitcoin exchanges mimic stock exchanges, though they're much more rudimentary offering only simple buy/sell/cancel orders.

If both had a price set at $101, they would just transact. Both parties think they can do a little bit better than the current offer. The width of the bid/ask spread is not universal by any means.

Putting a single large block of stock up for sale is problematic for one simple reason: Let's say you have 100,000 shares of a stock, and for some reason you decide today is the day to sell them, take your profits, and ride off into the sunset. So you call your broker (or log into your brokerage account) and put them up for sale. He puts in an order somewhere, the stock is sold, and your account is credited. Seems simple, right? Well...not so fast. Professionals - I'm keeping this simple, so please don't beat me up for it! The way stocks are bought and sold is through companies known as \"\"market makers\"\". These are entities which sit between the markets and you (and your broker), and when you want to buy or sell a stock, most of the time the order is ultimately handled somewhere along the line by a market maker. If you work with a large brokerage firm, sometimes they'll buy or sell your shares out of their own accounts, but that's another story. It is normal for there to be many, sometimes hundreds, of market makers who are all trading in the same equity. The bigger the stock, the more market makers it attracts. They all compete with each other for business, and they make their money on the spread between what they buy stock from people selling for and what they can get for it selling it to people who want it. Given that there could be hundreds of market makers on a particular stock (Google, Apple, and Microsoft are good examples of having hundreds of market makers trading in their stocks), it is very competitive. The way the makers compete is on price. It might surprise you to know that it is the market makers, not the markets, that decide what a stock will buy or sell for. Each market maker sets their own prices for what they'll pay to buy from sellers for, and what they'll sell it to buyers for. This is called, respectively, the \"\"bid\"\" and the \"\"ask\"\" prices. So, if there are hundreds of market makers then there could be hundreds of different bid and ask prices on the same stock. The prices you see for stocks are what are called the \"\"best bid and best ask\"\" prices. What that means is, you are being shown the highest \"\"bid\"\" price (what you can sell your shares for) and the best \"\"ask\"\" price (what you can buy those shares for) because that's what is required. That being said, there are many other market makers on the same stock whose bid prices are lower and ask prices are higher. Many times there will be a big clump of market makers all at the same bid/ask, or within fractions of a cent of each other, all competing for business. Trading computers are taught to seek out the best prices and the fastest trade fills they can. The point to this very simplistic lesson is that the market makers set the prices that shares trade at. They adjust those prices based (among other factors) on how much buying and selling volume they're seeing. If they see a wave of sell orders coming into the system then they'll start marking down their bid prices. This keeps them from paying too much for shares they're going to have to find a buyer for eventually, and it can sometimes slow down the pace of selling as investors and automated systems notice the price decline and decide to wait to sell. Conversely, if market makers see a wave of buy orders coming into the system, they'll start marking their ask prices up to maximize their gains, since they're selling you shares they bought from someone else, presumably at a lower price. But they typically adjust their prices up or down before they actually fill trades. (sneaky, eh?) Depending on how much volume there is on the shares of the company you're selling, and depending on whether there are more buyers than sellers at the moment, your share sell order may be filled at market by a market maker with no real consequence to the share's price. If the block is large enough then it's possible it will not all sell to one market maker, or it might not all happen in one transaction or even all at the same price. This is a pretty complex subject, as you can see, and I've cut a LOT of corners and oversimplified much to keep it comprehensible. But the short answer to your question is -- it depends. Hope this helps. Good luck!\"", "title": "" }, { "docid": "167151", "text": "Stop order is shorter term for stop-loss order. The point being that is intended as a protective measure. A buy stop order would be used to limit losses when an investor has sold a stock short. (Meaning that they have borrowed stock and sold it, in hopes that they can take advantage of a decline in the stock's price by replacing the borrowed stock later at a cheaper price. The idea is to limit losses due to a rising stock price.) Meanwhile, a sell stop order would be used to limit losses on a stock that an investor actually owns, by selling it before the price declines further. The important thing to keep in mind about stop orders is that they turn into market orders when the stop price is reached. This means that they will be filled at the best available price when the order is actually executed. In fast moving markets, this can be a price that is quite different from the stop price. A limit order allows an investor to ensure that they do not buy/sell a stock at more/less than the specified amount. The thing to keep in mind is that a limit order is not guaranteed to execute.

Unfortunately, you don't know the lowest time until the end of the day, and then you, uh can't buy the stock... Now the stock market is not random, but for your case, we can say that effectively, it is. So, when should you buy the stock to hopefully get the lowest price for the day? You should wait for 37% of the day, and then buy when it is lower than it has been for all of that day. Here is a quick example (with fake data): We have 18 points, and 37% of 18 is close to 7. So we discard the first 7 points - and just remember the lowest of those 7. We bear in mind that the lowest for the first 37% was 5. Now we wait until we find a stock which is lower than 5, and we buy at that point: This system is optimal for buying the stock at the lowest price for the day. Why? We want to find the best position to stop automatically ignoring. Why 37%? We know the answer to P(Being in position n) - it's 1/N as there are N toilets, and we can select just 1. Now, what is the chance we select them, given we're in position n? The chance of selecting any of the toilets from 0 to K is 0 - remember we're never going to buy then. So let's move on to the toilets from K+1 and onwards. If K+1 is better than all before it, we have this: But, K+1 might not be the best price from all past and future prices. Maybe K+2 is better. Let's look at K+2 For K+2 we have K/K+1, for K+3 we have K/K+2... So we have: This is a close approximation of the area under 1/x - especially as x → ∞ So 0 + 0 + ... + (K/N) x (1/K + 1/K+1 + 1/K+2 ... + 1/N-1) ≈ (K/N) x ln(N/K) and so P(K) ≈ (K/N) x ln(N/K) Now to simplify, say that x = K/N We can graph this, and find the maximum point so we know the maximum P(K) - or we can use calculus. Here's the graph: Here's the calculus: To apply this back to your situation with the stocks, if your stock updates every 30 seconds, and is open between 09:30 and 16:00, we have 6.5 hours = 390 minutes = 780 refreshes. You should keep track of the lowest price for the first 289 refreshes, and then buy your stock on the next best price. Because x = K/N, the chance of you choosing the best price is 37%. However, the chance of you choosing better than the average stock is above 50% for the day. Remember, this method just tries to mean you don't loose money within the day - if you want to try to minimise losses within the whole trading period, you should scale this up, so you wait 37% of the trading period (e.g. 37% of 3 months) and then select. The maths is taken from Numberphile - Mathematical Way to Choose a Toilet. Finally, one way to lose money a little slower and do some good is with Kiva.org - giving loans to people is developing countries.

If you buy EVE at \"\"market price\"\" you are entering a bid equal to the lowest ask price ($16.25). Its key to understand this rule: \"\"An order executes ONLY when both bid and ask meet. (bid = ask).\"\" So a market maker puts in a bid when he wants to buy but the trade only executes when an ASK price meets his BID price.

This does not happen often; it usually happens at the Initial Public Offering [the first time the company becomes \"\"public\"\" where anyone with access to the stock exchange can become a part-owner], plus maybe a few more times during the corporations existence. In this case, the corporation is offering new ownership in exchange for a price set the corporation (or a broker hired by the corporation). The price used for a public offering is the highest amount that the company believes it can get - this is a very complicated field, and involves many different methods of evaluating what the company should be worth. If the company sets the price too low, then they have missed out on possible value which would be earned by the previous, private shareholders (they would have gotten the same share % of a corporation which would now have more cash to spend, because of increased money paid by new shareholders). If the company sets the price too high, then the share subscription might only be partially filled, so there might not be enough cash to do what the company wanted. You can buy a share from another shareholder. This is more common - when you see the company's share price on the stock exchange, it is this type of transaction - buying out other current shareholders. The price here is simply set based on what current owners are willing to sell at. The \"\"Bid Price\"\" listed by an exchange is the current highest bid that a purchaser is offering for a single share. The \"\"Ask Price\"\" is the current lowest offer that a seller is offering to sell a single share they currently own.

Does Chocolate Cause Weight Gain?
[ { "docid": "MED-5284", "text": "Objective Habitual chocolate intake was recently found to be associated with lower body weight in three cross-sectional epidemiological studies. Our objective was to assess whether these cross-sectional results hold up in a more rigorous prospective analysis. Methods We used data from the Atherosclerosis Risk in Communities cohort. Usual dietary intake was assessed by questionnaire at baseline (1987–98), and after six years. Participants reported usual chocolate intake as the frequency of eating a 1-oz (∼28 g) serving. Body weight and height were measured at the two visits. Missing data were replaced by multiple imputation. Linear mixed-effects models were used to evaluate cross-sectional and prospective associations between chocolate intake and adiposity. Results Data were from 15,732 and 12,830 participants at the first and second visit, respectively. More frequent chocolate consumption was associated with a significantly greater prospective weight gain over time, in a dose-response manner. For instance, compared to participants who ate a chocolate serving less often than monthly, those who ate it 1–4 times a month and at least weekly experienced an increase in Body Mass Index (kg/m2) of 0.26 (95% CI 0.08, 0.44) and 0.39 (0.23, 0.55), respectively, during the six-year study period. In cross-sectional analyses the frequency of chocolate consumption was inversely associated with body weight. This inverse association was attenuated after excluding participants with preexisting obesity-related illness. Compared to participants without such illness, those with it had higher BMI and reported less frequent chocolate intake, lower caloric intake, and diets richer in fruits and vegetables. They tended to make these dietary changes after becoming ill. Conclusions Our prospective analysis found that a chocolate habit was associated with long-term weight gain, in a dose-response manner. Our cross-sectional finding that chocolate intake was associated with lower body weight did not apply to participants without preexisting serious illness.", "title": "Habitual Chocolate Consumption May Increase Body Weight in a Dose-Response Manner" }, { "docid": "MED-5287", "text": "There is limited research examining the relationship of candy consumption by adults on diet and health.

Although the effects of soy are not well understood, some breast cancer survivors increase their soy intake post-diagnosis in attempt to improve their prognosis. Therefore, we examined the role of soy isoflavone intake and the risk of breast cancer recurrence by hormone receptor status, menopausal status, and tamoxifen therapy. Materials and methods A cohort of 1954 female breast cancer survivors, diagnosed during 1997–2000, was prospective followed for 6.31 years and 282 breast cancer recurrences were ascertained. Isoflavone intake was assessed by mailing modified Block and supplemental soy food frequency questionnaires to participants, on average 23 months post-diagnosis. Risk of breast cancer recurrence, measured by hazard ratios (HR) and 95% confidence intervals (CI), was estimated using multivariable delayed-entry Cox proportional hazards models. Results Suggestive trends for a reduced risk of cancer recurrence were observed with increasing quintiles of daidzein and glycetin intake compared to no intake among postmenopausal women (P for trend: P = .08 for daidzein, P = .06 for glycetin) and among tamoxifen users (P = .10 for daidzein, P = .05 for glycetin). Among postmenopausal women treated with tamoxifen, there was an approximately 60% reduction in breast cancer recurrence comparing the highest to the lowest daidzein intakes (>1453 micrograms (µg)/day versus < 7.7 µg/day) (HR, 0.48; 95% CI, 0.21–0.79, P = .008). Conclusion Soy isoflavones consumed at levels comparable to those in Asian populations may reduce the risk of cancer recurrence in women receiving tamoxifen therapy and moreover, appears not to interfere with tamoxifen efficacy. Further confirmation is required in other large prospective studies before recommendations regarding soy intake can be issued to breast cancer survivors.", "title": "Soy Isoflavones and Risk of Cancer Recurrence in a Cohort of Breast Cancer Survivors: Life After Cancer Epidemiology (LACE) Study" }, { "docid": "MED-5289", "text": "BACKGROUND: Dark chocolate may have blood pressure-lowering properties. We conducted a prospective randomized open-label blinded end-point design trial to study a potential dose dependency of the presumed antihypertensive effect of dark chocolate by directly comparing low vs. higher doses of dark chocolate over the course of 3 months. METHODS: We enrolled a total of 102 patients with prehypertension/stage 1 hypertension and established cardiovascular end-organ damage or diabetes mellitus. Patients were randomly assigned to receive either 6 or 25 g/day of flavanol-rich dark chocolate for 3 months. The difference in 24-h mean blood pressure between groups was defined as the primary outcome measure. RESULTS: Significant reductions in mean ambulatory 24-h blood pressure were observed between baseline and follow-up in both groups (6 g/day: -2.3 mm Hg, 95% confidence interval -4.1 to -0.4; 25 g/day: -1.9 mm Hg, 95% confidence interval -3.6 to -0.2). There were no significant differences in blood pressure changes between groups. In the higher-dose group, a slight increase in body weight was noted (0.8 kg, 95% confidence interval 0.06 to 1.6).

Clinical and epidemiological studies suggest that cocoa-rich products reduce the risk of cardiovascular disease. According to this, cocoa has a high content in polyphenols, especially flavanols. Flavanols have been described to exert favorable effects on endothelium-derived vasodilation via the stimulation of nitric oxide-synthase, the increased availability of l-arginine, and the decreased degradation of NO. Cocoa may also have a beneficial effect by protecting against oxidative stress alterations and via decreased platelet aggregation, decreased lipid oxidation, and insulin resistance. These effects are associated with a decrease of blood pressure and a favorable trend toward a reduction in cardiovascular events and strokes. Previous meta-analyses have shown that cocoa-rich foods may reduce blood pressure. Long-term trials investigating the effect of cocoa products are needed to determine whether or not blood pressure is reduced on a chronic basis by daily ingestion of cocoa.

Findings: The tobacco industry had a playbook, a script, that emphasized personal responsibility, paying scientists who delivered research that instilled doubt, criticizing the “junk” science that found harms associated with smoking, making self-regulatory pledges, lobbying with massive resources to stifle government action, introducing “safer” products, and simultaneously manipulating and denying both the addictive nature of their products and their marketing to children. The script of the food industry is both similar to and different from the tobacco industry script.

The purpose of this study was to investigate associations between typical frequency of candy consumption and body weight status and select cardiovascular risk factors among adults in the United States. Methods Using data collected in the 2003–2006 National Health and Nutrition Examination Surveys (NHANES), adults were categorized as infrequent (≤ 3 eating occasions [EO]/month), moderate (> 3 EO/month and ≤ 3.5 EO/week), or frequent (> 3.5 EO/week) candy consumers based on the combined frequency of chocolate and other candy consumption over the previous 12 months. Weight and adiposity status were analyzed using logistic regression models, and blood pressure, lipids, and insulin sensitivity were analyzed using linear regression models. Models were adjusted for age, sex and race/ethnicity, and also for additional covariates with potential associations with the outcomes. Appropriate statistical weights were used to yield results generalizable to the US population. Results Frequency of candy consumption was not associated with the risk of obesity, overweight/obesity, elevated waist circumference, elevated skinfold thickness, blood pressure, low density lipoprotein (LDL) or high density lipoprotein (HDL) cholesterol, triglycerides, or insulin resistance. Increased frequency of candy consumption was associated with higher energy intakes and higher energy adjusted intakes of carbohydrates, total sugars and added sugars, total fat, saturated fatty acids and monounsaturated fatty acids (p < 0.05), and lower adjusted intakes of protein and cholesterol (p < 0.001). Conclusions Increased frequency of candy consumption among adults in the United States was not associated with objective measures of adiposity or select cardiovascular risk factors, despite associated dietary differences. Given the cross-sectional study design, however, it cannot be concluded that candy consumption does not cause obesity or untoward levels of cardiovascular risk markers. The lack of an association between frequency of candy consumption and cardiovascular risk factors could be due to reduced intake of candy among the overweight due to dieting or a health professional’s recommendations. Additionally, it is important to note that the analysis was based on frequency of candy consumption and not amount of candy consumed.

Composite samples were characterized for percent fat (% fat), percent nonfat cocoa solids (% NFCS), antioxidant level by ORAC, total polyphenols, epicatechin, catechin, total monomers, and flavan-3-ol oligomers and polymers (procyanidins). On a gram weight basis epicatechin and catechin content of the products follow in decreasing order: cocoa powder > baking chocolate > dark chocolate = baking chips > milk chocolate > chocolate syrup. Analysis of the monomer and oligomer profiles within product categories shows there are two types of profiles: (1) products that have high monomers with decreasing levels of oligomers and (2) products in which the level of dimers is equal to or greater than the monomers. Results show a strong correlation (R(2) = 0.834) of epicatechin to the level of % NFCS and also very good correlations for N = 2-5 oligomers to % NFCS. A weaker correlation was observed for catechin to % NFCS (R(2) = 0.680).

Objective: The objective was to determine the relation between nut consumption and long-term weight change.

We prospectively evaluated the dietary intake of nuts and subsequent weight changes from 1991 to 1999. Results: Women who reported eating nuts ≥2 times/wk had slightly less mean (± SE) weight gain (5.04 ± 0.12 kg) than did women who rarely ate nuts (5.55 ± 0.04 kg) (P for trend < 0.001). For the same comparison, when total nut consumption was subdivided into peanuts and tree nuts, the results were similar (ie, less weight gain in women eating either peanuts or tree nuts ≥2 times/wk). The results were similar in normal-weight, overweight, and obese participants. In multivariate analyses in which lifestyle and other dietary factors were controlled for, we found that greater nut consumption (≥2 times/wk compared with never/almost never) was associated with a slightly lower risk of obesity (hazard ratio: 0.77; 95% CI: 0.57, 1.02; P for trend = 0.003). Conclusions: Higher nut consumption was not associated with greater body weight gain during 8 y of follow-up in healthy middle-aged women.

Nut consumption has been associated with several health benefits, such as antioxidant, hypocholesterolemic, cardioprotective, anticancer, anti-inflammatory, and antidiabetic benefits, among other functional properties. However, although nuts possess these many health benefits, their consumption has been hampered by a lack of adequate information regarding those benefits.

RECENT FINDINGS: Experimental studies have shown that short-term partial sleep restriction decreases glucose tolerance, increases sympathetic tone, elevates cortisol concentrations, decreases the satiety hormone leptin, increases the appetite-stimulating hormone ghrelin, and increases hunger and appetite. Short sleep duration might increase the risk of becoming obese, because it does not allow the recovery of a hormonal profile facilitating appetite control. Lack of sleep could also lead to weight gain and obesity by increasing the time available for eating and by making the maintenance of a healthy lifestyle more difficult. Furthermore, the increased fatigue and tiredness associated with sleeping too little could lessen one's resolve to follow exercise regimens. SUMMARY: Short sleep duration appears to be a novel and independent risk factor for obesity. With the growing prevalence of chronic sleep restriction, any causal association between reduced sleep and obesity would have substantial importance from a public health standpoint.

Short-term interventions of at most 2 weeks indicate that high doses of cocoa can improve endothelial function and reduce blood pressure (BP) due to the action of the cocoa polyphenols, but the clinical effect of low habitual cocoa intake on BP and the underlying BP-lowering mechanisms are unclear. OBJECTIVE: To determine effects of low doses of polyphenol-rich dark chocolate on BP. DESIGN, SETTING, AND PARTICIPANTS: Randomized, controlled, investigator-blinded, parallel-group trial involving 44 adults aged 56 through 73 years (24 women, 20 men) with untreated upper-range prehypertension or stage 1 hypertension without concomitant risk factors. The trial was conducted at a primary care clinic in Germany between January 2005 and December 2006. INTERVENTION: Participants were randomly assigned to receive for 18 weeks either 6.3 g (30 kcal) per day of dark chocolate containing 30 mg of polyphenols or matching polyphenol-free white chocolate. MAIN OUTCOME MEASURES: Primary outcome measure was the change in BP after 18 weeks. Secondary outcome measures were changes in plasma markers of vasodilative nitric oxide (S-nitrosoglutathione) and oxidative stress (8-isoprostane), and bioavailability of cocoa polyphenols. RESULTS: From baseline to 18 weeks, dark chocolate intake reduced mean (SD) systolic BP by -2.9 (1.6) mm Hg (P < .001) and diastolic BP by -1.9 (1.0) mm Hg (P < .001) without changes in body weight, plasma levels of lipids, glucose, and 8-isoprostane. Hypertension prevalence declined from 86% to 68%. The BP decrease was accompanied by a sustained increase of S-nitrosoglutathione by 0.23 (0.12) nmol/L (P < .001), and a dark chocolate dose resulted in the appearance of cocoa phenols in plasma. White chocolate intake caused no changes in BP or plasma biomarkers. CONCLUSIONS: Data in this relatively small sample of otherwise healthy individuals with above-optimal BP indicate that inclusion of small amounts of polyphenol-rich dark chocolate as part of a usual diet efficiently reduced BP and improved formation of vasodilative nitric oxide.

OBJECTIVE: The objective was to determine the relative contributions of increased energy intake and reduced physical activity to the US obesity epidemic. DESIGN: We predicted the changes in weight from the changes in estimated energy intakes in US children and adults between the 1970s and 2000s. The increased US food energy supply (adjusted for wastage and assumed to be proportional to energy intake) was apportioned to children and adults and inserted into equations that relate energy intake to body weight derived from doubly labeled water studies. The weight increases predicted from the equations were compared with weight increases measured in representative US surveys over the same period. RESULTS: For children, the measured weight gain was 4.0 kg, and the predicted weight gain for the increased energy intake was identical at 4.0 kg. For adults, the measured weight gain was 8.6 kg, whereas the predicted weight gain was somewhat higher (10.8 kg).

First, reducing obesity will require modifying both energy intake and energy expenditure and not simply focusing on either alone. Food restriction alone will not be effective in reducing obesity if human physiology is biased toward achieving energy balance at a high energy flux (i.e. at a high level of energy intake and expenditure). In previous environments a high energy flux was achieved with a high level of physical activity but in today's sedentary environment it is increasingly achieved through weight gain. Matching energy intake to a high level of energy expenditure will likely be more a more feasible strategy for most people to maintain a healthy weight than restricting food intake to meet a low level of energy expenditure. Second, from an energy balance point of view we are likely to be more successful in preventing excessive weight gain than in treating obesity. This is because the energy balance system shows much stronger opposition to weight loss than to weight gain. While large behavior changes are needed to produce and maintain reductions in body weight, small behavior changes may be sufficient to prevent excessive weight gain.

OBJECTIVE: The objective of this study is to assess the association between the amount and type of dietary protein, and subsequent changes in weight and waist circumference (WC). METHODS: 89,432 men and women from five countries participating in European Prospective Investigation into Cancer and Nutrition (EPIC) were followed for a mean of 6.5 years. Associations between the intake of protein or subgroups of protein (from animal and plant sources) and changes in weight (g per year) or WC (cm per year) were investigated using gender and centre-specific multiple regression analyses. Adjustments were made for other baseline dietary factors, baseline anthropometrics, demographic and lifestyle factors and follow-up time. We used random effect meta-analyses to obtain pooled estimates across centres. RESULTS: Higher intake of total protein, and protein from animal sources was associated with subsequent weight gain for both genders, strongest among women, and the association was mainly attributable to protein from red and processed meat and poultry rather than from fish and dairy sources. There was no overall association between intake of plant protein and subsequent changes in weight. No clear overall associations between intakes of total protein or any of the subgroups and changes in WC were present. The associations showed some heterogeneity between centres, but pooling of estimates was still considered justified. CONCLUSION: A high intake of protein was not found associated with lower weight or waist gain in this observational study. In contrast, protein from food items of animal origin, especially meat and poultry, seemed to be positively associated with long-term weight gain.

All the prospective epidemiological studies demonstrate that a higher intake of whole grains is associated with lower BMI and body weight gain. However, these results do not clarify whether whole grain consumption is simply a marker of a healthier lifestyle or a factor favoring \"per se\" lower body weight. Habitual whole grain consumption seems to cause lower body weight by multiple mechanisms such as lower energy density of whole grain based products, lower glycemic index, fermentation of non digestible carbohydrates (satiety signals) and finally by modulating intestinal microflora. In contrast with epidemiological evidence, the results of few clinical trials do not confirm that a whole grain low-calorie diet is more effective in reducing body weight than a refined cereal diet, but their results may have been affected by small sample size or short duration of the intervention. Therefore, further intervention studies with adequate methodology are needed to clarify this question. For the time being, whole grain consumption can be recommended as one of the features of the diet that may help control body weight but also because is associated with a lower risk to develop type 2 diabetes, cardiovascular diseases and cancer.

Methods Forty-six overweight adults (average age, 57.4 years; 28 women, 18 men) with elevated waist circumference and 1 or more additional signs of metabolic syndrome were randomly assigned to two 8-week sequences of walnut-enriched ad libitum diet and ad libitum diet without walnuts, which were separated by a 4-week washout period. The primary outcome measure was the change in flow-mediated vasodilation (FMD) of the brachial artery. Secondary measures included serum lipid panel, fasting glucose and insulin, Homeostasis Model Assessment–Insulin Resistance values, blood pressure, and anthropometric measures. Results FMD improved significantly from baseline when subjects consumed a walnut-enriched diet as compared with the control diet (1.4% ± 2.4% versus 0.3% ± 1.5%; p = 0.019). Beneficial trends in systolic blood pressure reduction were seen, and maintenance of the baseline anthropometric values was also observed. Other measures were unaltered.

RECENT FINDINGS Trials in nonmuscle-invasive bladder cancer are evaluating the role of immunotherapy and agents targeting vascular endothelial growth factor (VEGF) or fibroblast growth factor receptor-3. In muscle-invasive bladder cancer, neoadjuvant studies have focused on combining VEGF agents with chemotherapy; adjuvant studies are testing vaccines and agents targeting the human epidermal growth factor receptor 2, p53, and Hsp27. In the first-line treatment of metastatic urothelial carcinoma, tubulin, cytotoxic T-lymphocyte antigen 4, Hsp27, and p53 are novel targets in clinical trials. The majority of targeted agents studied in urothelial carcinoma are in the second-line setting; new targets include CD105, polo-like kinase-1, phosphatidylinositide 3-kinases (PI3K), transforming growth factor β receptor/activin receptor-like kinase β, estrogen receptor, and the hepatocyte growth factor receptor (HGFR or MET).

Some studies suggest a dominant role for EGFR, a notion of renewed interest given the development of dual HER2/EGFR small-molecule inhibitors. Other studies point to HER3 as the primary coreceptor. To clarify the relative contributions of EGFR and HER3 to HER2 signaling, we studied receptor knockdown via small interfering RNA technology across a panel of six HER2-overexpressing cell lines. Interestingly, HER3 was as critical as HER2 for maintaining cell proliferation in most cell lines, whereas EGFR was dispensable. Induction of HER3 knockdown in the HER2-overexpressing BT474M1 cell line was found to inhibit growth in three-dimensional culture and induce rapid tumor regression of in vivo xenografts. Furthermore, preferential phosphorylation of HER3, but not EGFR, was observed in HER2-amplified breast cancer tissues. Given these data suggesting HER3 as an important therapeutic target, we examined the activity of pertuzumab, a HER2 antibody that inhibits HER3 signaling by blocking ligand-induced HER2/HER3 heterodimerization. Pertuzumab inhibited ligand-dependent morphogenesis in three-dimensional culture and induced tumor regression in the heregulin-dependent MDA-MB-175 xenograft model. Importantly, these activities of pertuzumab were distinct from those of trastuzumab, a monoclonal antibody currently used for treatment of HER2-amplified breast cancer patients.

GM-CSF expression resulted in grade I-III increases in neutrophil counts in four of six patients at the MTD. Tumour responses were shown in injected and non-injected tumours. Ten patients were radiographically evaluable for objective responses; non-evaluable patients had contraindications to contrast medium (n=2) or no post-treatment scans (n=2). According to Response Evaluation Criteria in Solid Tumors (RECIST), three patients had partial response, six had stable disease, and one had progressive disease.

Here, we aimed to identify molecular profiles specific for treatment resistance to the current standard of care of concomitant chemoradiotherapy with the alkylating agent temozolomide. PATIENTS AND METHODS Gene expression profiles of 80 glioblastomas were interrogated for associations with resistance to therapy. Patients were treated within clinical trials testing the addition of concomitant and adjuvant temozolomide to radiotherapy. RESULTS An expression signature dominated by HOX genes, which comprises Prominin-1 (CD133), emerged as a predictor for poor survival in patients treated with concomitant chemoradiotherapy (n = 42; hazard ratio = 2.69; 95% CI, 1.38 to 5.26; P = .004). This association could be validated in an independent data set. Provocatively, the HOX cluster was reminiscent of a \"self-renewal\" signature (P = .008; Gene Set Enrichment Analysis) recently characterized in a mouse leukemia model. The HOX signature and EGFR expression were independent prognostic factors in multivariate analysis, adjusted for the O-6-methylguanine-DNA methyltransferase (MGMT) methylation status, a known predictive factor for benefit from temozolomide, and age. Better outcome was associated with gene clusters characterizing features of tumor-host interaction including tumor vascularization and cell adhesion, and innate immune response.

Multiple angiogenic polypeptides are known, and we have determined the expression of seven of these in primary human breast cancers; the relationship of expression to estrogen receptor and vascular density was also examined. Vascular endothelial growth factor (VEGF) and its four isoforms (121, 165, 189, and 206 amino acids), transforming growth factor (TGF)-beta1, pleiotrophin, acidic and basic fibroblast growth factor (FGF), placental growth factor, and thymidine phosphorylase (platelet-derived endothelial cell growth factor) were quantitated by RNase protection analysis. beta-FGF was also measured by ELISA. The estrogen receptor (ER), epidermal growth factor receptor, and vascular density were analyzed in 64 primary breast cancers. All tumors expressed at least six different vascular growth factors. VEGF was most abundant, and the transcript for the 121-amino acid form predominated. Other angiogenic factors expressed at high levels were thymidine phosphorylase and TGF-beta1. Expression of most of the angiogenic factors did not correlate with that of ER or vascular density. However, thymidine phosphorylase did, with a correlation coefficient of 0.3 (P = 0.03). There were significant associations of pleiotrophin with acidic FGF expression (P = 0.001) and TGF-beta with platelet-derived endothelial cell growth factor expression (P = 0.001). Thus, angiogenesis may involve a coordinate regulation of some vascular growth factors. High VEGF expression correlated with poor prognosis in univariate analysis (P = 0.03), as did ER and epidermal growth factor receptor expression. Basic FGF was also assessed by ELISA and was more highly expressed in tumors than normal breast tissues (median, 346 microg/ml cytosol; range, 54-1323 versus median, 149; range, 32-509; P = 0.01).

Despite the success of these drugs, their efficacy is limited in patients whose tumors demonstrate de novo or acquired resistance to treatment. The β1 integrin resides on the membrane of the breast cancer cell, activating several elements of breast tumor progression including proliferation and survival. METHODS We developed a panel of HER2-overexpressing cell lines resistant to L, T, and the potent LT combination through long-term exposure and validated these models in 3D culture. Parental and L/T/LT-resistant cells were subject to HER2 and β1 integrin inhibitors in 3D and monitored for 12 days, followed by quantification of colony number. Parallel experiments were conducted where cells were either stained for Ki-67 and Terminal deoxynucleotidyl transferase dUTP nick end labeling (TUNEL) or harvested for protein and analyzed by immunoblot. Results were subjected to statistical testing using analysis of variance and linear contrasts, followed by adjustment with the Sidak method. RESULTS Using multiple cell lines including BT474 and HCC1954, we reveal that in L and LT resistance, where phosphorylation of EGFR/HER1, HER2, and HER3 are strongly inhibited, kinases downstream of β1 integrin--including focal adhesion kinase (FAK) and Src--are up-regulated. Blockade of β1 by the antibody AIIB2 abrogates this up-regulation and functionally achieves significant growth inhibition of L and LT resistant cells in 3D, without dramatically affecting the parental cells. SiRNA against β1 as well as pharmacologic inhibition of FAK achieve the same growth inhibitory effect. In contrast, trastuzumab-resistant cells, which retain high levels of phosphorylated EGFR/HER1, HER2, and HER3, are only modestly growth-inhibited by AIIB2. CONCLUSIONS Our data suggest that HER2 activity, which is suppressed in resistance involving L but not T alone, dictates whether β1 mediates an alternative pathway driving resistance.

Invadopodia with short lifetimes are motile, whereas long-lived invadopodia tend to be stationary.

We reanalyzed EGFR deletion/mutation using two highly sensitive techniques that detect abnormalities in samples with 5% to 10% tumor cellularity. KRAS mutation was analyzed by direct sequencing. RESULTS Thirty patients (15%) had KRAS mutations, 34 (17%) had EGFR exon 19 deletion or exon 21 L858R mutations, and 61 (38%) had high EGFR gene copy (FISH positive).

These genetic alterations rarely, if ever, are observed in breast tumors. However, various lines of evidence suggest that WNT signaling may also be de-regulated in breast cancer. Most breast tumors show hypermethylation of the promoter region of secreted Frizzled-related protein 1 (sFRP1), a negative WNT pathway regulator, leading to downregulation of its expression. As a consequence, WNT signaling is enhanced and may contribute to proliferation of human breast tumor cells. We previously demonstrated that, in addition to the canonical WNT/β-catenin pathway, WNT signaling activates the extracellular signal-regulated kinase 1/2 (ERK1/2) pathway in mouse mammary epithelial cells via epidermal growth factor receptor (EGFR) transactivation. Using the WNT modulator sFRP1 and short interfering RNA-mediated Dishevelled (DVL) knockdown, we interfered with autocrine WNT signaling at the ligand-receptor level. The impact on proliferation was measured by cell counting, YOPRO, and the MTT (3-[4,5-dimethylthiazol-2-yl]-2,5-diphenyl-tetrazolium bromide) assay; β-catenin, EGFR, ERK1/2 activation, and PARP (poly [ADP-ribose]polymerase) cleavages were assessed by Western blotting after treatment of human breast cancer cell lines with conditioned media, purified proteins, small-molecule inhibitors, or blocking antibodies. Phospho-DVL and stabilized β-catenin are present in many breast tumor cell lines, indicating autocrine WNT signaling activity. Interfering with this loop decreases active β-catenin levels, lowers ERK1/2 activity, blocks proliferation, and induces apoptosis in MDA-MB-231, BT474, SkBr3, JIMT-1, and MCF-7 cells. The effects of WNT signaling are mediated partly by EGFR transactivation in human breast cancer cells in a metalloprotease- and Src-dependent manner. Furthermore, Wnt1 rescues estrogen receptor-positive (ER+) breast cancer cells from the anti-proliferative effects of 4-hydroxytamoxifen (4-HT) and this activity can be blocked by an EGFR tyrosine kinase inhibitor. Our data show that interference with autocrine WNT signaling in human breast cancer reduces proliferation and survival of human breast cancer cells and rescues ER+ tumor cells from 4-HT by activation of the canonical WNT pathway and EGFR transactivation.

Whereas in the adult, UUO stimulates renal cellular proliferation, UUO in the neonate reduces nephrogenesis, glomerular maturation, and tubular cellular proliferation. This is accompanied by a proportionately greater compensatory growth of the intact opposite kidney in the neonate. Impaired renal growth and tubular atrophy are likely owing at least in part to stimulation of renal tubular apoptosis.

Due to their small size and non-invasive nature, these dormant tumors remain asymptomatic and, in most cases, undetected. With advances in diagnostic imaging and molecular biology, it is now becoming clear that such neoplasms can remain in an asymptomatic, dormant stage for considerable periods of time without expanding in size. Although a number of processes may play a role in thwarting the expansion of microscopic tumors, one critical mechanism behind tumor dormancy is the ability of the tumor population to induce angiogenesis. Although cancer can arise through multiple pathways, it is assumed that essentially most tumors begin as microscopic, non-angiogenic neoplasms which cannot expand in size until vasculature is established. It is now becoming clear that cancer does not progress through a continuous exponential growth and mass expansion. Clinical cancer is usually manifested only in late, unavoidably symptomatic stages of the disease when tumors are sufficiently large to be readily detected. While dormancy in primary tumors is best defined as the time between the carcinogenic transformation event and the onset of inexorable progressive growth, it can also occur as minimal residual or occult disease from treated tumors or as micro-metastases.

Colorectal cancer initiating cells (CCICs) are a small subpopulation responsible for malignant behaviors of colorectal cancer. Aberrant activation of the Wnt pathways regulates the self-renewal of CCIC. However, the underlying mechanism(s) remain poorly understood. METHODS Via retroviral library screening, we identified Nuclear Receptor-Interacting Protein 2 (NRIP2) as a novel interactor of the Wnt pathway from enriched colorectal cancer colosphere cells. The expression levels of NRIP2 and retinoic acid-related orphan receptor β (RORβ) were further examined by FISH, qRT-PCR, IHC and Western blot. NRIP2 overexpressed and knockdown colorectal cancer cells were produced to study the role of NRIP2 in Wnt pathway. We also verified the binding between NRIP2 and RORβ and investigated the effect of RORβ on CCICs both in vitro and in vivo. Genechip-scanning speculated downstream target HBP1. Western blot, ChIP and luciferase reporter were carried to investigate the interaction between NRIP2, RORβ, and HBP1. RESULTS NRIP2 was significantly up-regulated in CCICs from both cell lines and primary colorectal cancer tissues. Reinforced expression of NRIP2 increased Wnt activity, while silencing of NRIP2 attenuated Wnt activity.

NRIP2 prevented RORβ to bind with downstream HBP1 promoter regions and reduced the transcription of HBP1. This, in turn, attenuated the HBP1-dependent inhibition of TCF4-mediated transcription.

EML4-ALK fusion is mutually exclusive with epidermal growth factor receptor (EGFR) mutations. To understand the impact of EML4-ALK on the prognosis of non-small cell lung cancer, we examined EML4-ALK fusion in lung adenocarcinoma from patients with wild-type EGFR and analyzed their clinical treatment outcomes. METHODS Lung adenocarcinoma patients with malignant pleural effusions having wild-type EGFR and measurable target lesions were enrolled for EML4-ALK analysis by reverse transcription-polymerase chain reaction and direct sequencing. Demographic data, EML4-ALK status, and survival data were analyzed. We also performed fluorescence in situ hybridization on some available tumor samples to validate the PCR result. In addition, K-ras mutation was analyzed for patients without EML4-ALK fusion genes. RESULTS A total of 116 patients with wild-type EGFR sequencing results had complete clinical data for analysis. No patients received ALK inhibitor therapy. There were 39 patients (34%) with the EML4-ALK fusion gene. The concordance rate between reverse transcription-polymerase chain reaction and fluorescence in situ hybridization was 85%. The K-ras mutation rate for patients without EML4-ALK fusion gene was 6.5%. By multivariate analysis, patients who had better performance status (p < 0.001) and EML4-ALK translocation (p = 0.017) had longer overall survival.

The VEGF/VEGF-receptor axis is composed of multiple ligands and receptors with overlapping and distinct ligand-receptor binding specificities, cell-type expression, and function. Activation of the VEGF-receptor pathway triggers a network of signaling processes that promote endothelial cell growth, migration, and survival from pre-existing vasculature. In addition, VEGF mediates vessel permeability, and has been associated with malignant effusions. More recently, an important role for VEGF has emerged in mobilization of endothelial progenitor cells from the bone marrow to distant sites of neovascularization. The well-established role of VEGF in promoting tumor angiogenesis and the pathogenesis of human cancers has led to the rational design and development of agents that selectively target this pathway. Studies with various anti-VEGF/VEGF-receptor therapies have shown that these agents can potently inhibit angiogenesis and tumor growth in preclinical models. Recently, an anti-VEGF antibody (bevacizumab), when used in combination with chemotherapy, was shown to significantly improve survival and response rates in patients with metastatic colorectal cancer and thus, validate VEGF pathway inhibitors as an important new treatment modality in cancer therapy.", "title": "Role of the vascular endothelial growth factor pathway in tumor growth and angiogenesis." }, { "docid": "5289038", "text": "Immune clearance and resource limitation (via red blood cell depletion) shape the peaks and troughs of malaria parasitemia, which in turn affect disease severity and transmission.

We aimed to determine the energy metabolic pathway(s) used by MDSC, establish its impact on their immunosuppressive function, and test whether its inhibition blocks MDSC and enhances antitumor therapies.

We found that TAMs were significantly frequent in high histopathological grade breast cancer patients. Breast cancer patients with a high density of TAMs had significantly lower rates of disease-free survival and 5-year overall survival than patients with low density of TAMs. Furthermore, high-infiltration of TAMs indicated worse survival rate for patients with node-negative breast cancer. In conclusion, the number of TAMs in the tumor stroma is an independent predictor of survival time for breast cancer patients.

METHODS This randomized, multicenter, placebo-controlled, double-blind trial of IM AN1792 225 microg plus the adjuvant QS-21 50 microg (300 patients) and saline (72 patients) included patients aged 50 to 85 years with probable AD, Mini-Mental State Examination (MMSE) 15 to 26.

RESULTS Following reports of meningoencephalitis (overall 18/300 [6%]), immunization was stopped after one (2 patients), two (274 patients), or three (24 patients) injections. Of the 300 AN1792(QS-21)-treated patients, 59 (19.7%) developed the predetermined antibody response. Double-blind assessments were maintained for 12 months. No significant differences were found between antibody responder and placebo groups for ADAS-Cog, Disability Assessment for Dementia, Clinical Dementia Rating, MMSE, or Clinical Global Impression of Change, but analyses of the z-score composite across the NTB revealed differences favoring antibody responders (0.03 +/- 0.37 vs -0.20 +/- 0.45; p = 0.020).

Direct oncolysis plus granulocyte-macrophage colony-stimulating factor (GM-CSF) expression also stimulates shutdown of tumour vasculature and antitumoral immunity. We aimed to assess intratumoral injection of JX-594 in patients with refractory primary or metastatic liver cancer. METHODS Between Jan 4, 2006, and July 4, 2007, 14 patients with histologically confirmed refractory primary or metastatic liver tumours (up to 10.9 cm total diameter) that were amenable to image-guided intratumoral injections were enrolled into this non-comparative, open-label, phase I dose-escalation trial (standard 3x3 design; two to six patients for each dose with 12-18 estimated total patients). Patients received one of four doses of intratumoral JX-594 (10(8) plaque-forming units [pfu], 3x10(8) pfu, 10(9) pfu, or 3x10(9) pfu) every 3 weeks at Dong-A University Hospital (Busan, South Korea). Patients were monitored after treatment for at least 48 h in hospital and for at least 4 weeks as out-patients. Adverse event-monitoring according to the National Cancer Institute Common Toxicity Criteria (version 3) and standard laboratory toxicity grading for haematology, liver and renal function, coagulation studies, serum chemistry, and urinalysis were done. The primary aims were to ascertain the maximum-tolerated dose (MTD) and safety of JX-594 treatment. Data were also collected on pharmacokinetics, pharmacodynamics, and efficacy. Analysis was per protocol. This study is registered with ClinicalTrials.gov, number NCT00629759. FINDINGS Of 22 patients with liver tumours who were assessed for eligibility, eight patients did not meet inclusion criteria. Therefore, 14 patients, including those with hepatocellular, colorectal, melanoma, and lung cancer, were enrolled. Patients were heavily pretreated (5.6 previous treatments, SD 2.8, range 2.0-12.0) and had large tumours (7.0 cm diameter, SD 2.7, range 1.8-10.9). Patients received a mean of 3.4 (SD 2.2, range 1.0-8.0) cycles of JX-594. All patients were evaluable for toxicity. All patients experienced grade I-III flu-like symptoms, and four had transient grade I-III dose-related thrombocytopenia. Grade III hyperbilirubinaemia was dose-limiting in both patients at the highest dose; the MTD was therefore 1x10(9) pfu. JX-594 replication-dependent dissemination in blood was shown, with resultant infection of non-injected tumour sites. GM-CSF expression resulted in grade I-III increases in neutrophil counts in four of six patients at the MTD. Tumour responses were shown in injected and non-injected tumours. Ten patients were radiographically evaluable for objective responses; non-evaluable patients had contraindications to contrast medium (n=2) or no post-treatment scans (n=2). According to Response Evaluation Criteria in Solid Tumors (RECIST), three patients had partial response, six had stable disease, and one had progressive disease.

Immunohistochemistry was performed on tissue microarray sections from WDTC (n=33), PDTC (n=37), and ATC (n=20) using macrophage-specific markers.

However, marrow lacks mature dendritic cells, and substantial numbers of proliferating less-mature cells have yet to be identified. The methodology for inducing dendritic cell growth that was recently described for mouse blood now has been modified to MHC class II-negative precursors in marrow. A key step is to remove the majority of nonadherent, newly formed granulocytes by gentle washes during the first 2-4 d of culture. This leaves behind proliferating clusters that are loosely attached to a more firmly adherent \"stroma. \" At days 4-6 the clusters can be dislodged, isolated by 1-g sedimentation, and upon reculture, large numbers of dendritic cells are released. The latter are readily identified on the basis of their distinct cell shape, ultrastructure, and repertoire of antigens, as detected with a panel of monoclonal antibodies. The dendritic cells express high levels of MHC class II products and act as powerful accessory cells for initiating the mixed leukocyte reaction. Neither the clusters nor mature dendritic cells are generated if macrophage colony-stimulating factor rather than granulocyte/macrophage colony-stimulating factor (GM-CSF) is applied. Therefore, GM-CSF generates all three lineages of myeloid cells (granulocytes, macrophages, and dendritic cells).

We show that mature neutrophils, despite their inability to proliferate, express high levels of PCNA exclusively in their cytosol and constitutively associated with procaspases, presumably to prevent their activation. Notably, cytosolic PCNA abundance decreased during apoptosis, and increased during in vitro and in vivo exposure to the survival factor granulocyte colony-stimulating factor (G-CSF). Peptides derived from the cyclin-dependent kinase inhibitor p21, which compete with procaspases to bind PCNA, triggered neutrophil apoptosis thus demonstrating that specific modification of PCNA protein interactions affects neutrophil survival. Furthermore, PCNA overexpression rendered neutrophil-differentiated PLB985 myeloid cells significantly more resistant to TNF-related apoptosis-inducing ligand- or gliotoxin-induced apoptosis. Conversely, a decrease in PCNA expression after PCNA small interfering RNA transfection sensitized these cells to apoptosis.

Multiple mutations in GNB1 affect the protein interface that binds Gα subunits as well as downstream effectors and disrupt Gα interactions with the Gβγ dimer. Different mutations in Gβ proteins clustered partly on the basis of lineage; for example, all 11 GNB1 K57 mutations were in myeloid neoplasms, and seven of eight GNB1 I80 mutations were in B cell neoplasms. Expression of patient-derived GNB1 variants in Cdkn2a-deficient mouse bone marrow followed by transplantation resulted in either myeloid or B cell malignancies. In vivo treatment with the dual PI3K-mTOR inhibitor BEZ235 suppressed GNB1-induced signaling and markedly increased survival.

Here, we investigated whether activation of AMP-activated protein kinase (AMPK) could suppress macrophage proliferation. Ox-LDL-induced proliferation of mouse peritoneal macrophages was assessed by [(3)H]thymidine incorporation and cell counting assays. The proliferation was significantly inhibited by the AMPK activator 5-aminoimidazole-4-carboxamide ribonucleoside (AICAR) and restored by dominant-negative AMPKalpha1, suggesting that AMPK activation suppressed macrophage proliferation. AICAR partially suppressed Ox-LDL-induced ERK1/2 phosphorylation and GM-CSF expression, suggesting that another mechanism is also involved in the AICAR-mediated suppression of macrophage proliferation. AICAR suppressed GM-CSF-induced macrophage proliferation without suppressing p38 MAPK/Akt signaling. GM-CSF suppressed p53 phosphorylation and expression and induced Rb phosphorylation.

However, little is known about their effects on cholesterol metabolism when given in native, unpurified form and in amounts achievable in the diet. The objective of this investigation was to test the hypothesis that intrinsic phytosterols present in unmodified foods alter whole-body cholesterol metabolism. Subjects/Methods Twenty out of 24 subjects completed a randomized, crossover feeding trial where all meals were provided by a metabolic kitchen. Each subject consumed two diets for 4 weeks each. The diets differed in phytosterol content (phytosterol-poor diet, 126 mg phytosterols/2000 kcal; phytosterol-abundant diet, 449 mg/2000 kcal) but were otherwise matched for nutrient content. Cholesterol absorption and excretion were determined by gas chromatograph/mass spectrometry after oral administration of stable isotopic tracers. Results The phytosterol-abundant diet resulted in lower cholesterol absorption [54.2 ± 2.2 % (95% confidence interval, 50.5%, 57.9%) vs. 73.2 ± 1.3% (69.5%, 76.9%), P<0.0001] and 79% higher fecal cholesterol excretion [1322 ± 112 (1083.2, 1483.3) vs. 739 ± 97 mg/day (530.1, 930.2), P<0.0001] relative to the phytosterol-poor diet. Plasma lathosterol/cholesterol ratio rose 82% [from 0.71 ± 0.11 (0.41, 0.96) to 1.29 ± 0.14 μg/mg (0.98, 1.53), (P<0.0001)]. LDL-cholesterol was similar between diets.

We examined the association of dietary lignan intakes with survival in 1122 women with primary, incident, histologically confirmed breast cancer identified between 1996 and 2001, and with vital status determined through December 31, 2006. Diet in the 12–24 months before diagnosis was assessed with an extensive food frequency questionnaire, and potential confounders assessed from an extensive epidemiologic interview and abstracted clinical data. Lignan intake was calculated using published food composition data. Hazard ratios (HR), and 95% confidence intervals (CIs) for dietary lignan intakes with all cause, and breast cancer mortality were estimated using Cox proportional hazards adjusting for age, education, race, total energy intake, tumor stage, and body mass index. Of the 1122 women with complete dietary data, 160 had died by the end of follow-up. Among postmenopausal women only, those in the highest versus lowest quartile of lignan intakes had a statistically significant reduction in the risk of all cause mortality (HR 0.49, 95% CI 0.26–0.91) and a significantly reduced risk of breast cancer mortality (HR 0.29, 95% CI 0.11–0.76).

Rainwater samples were collected at about 50 locations in The Netherlands in a four week period. The samples were analysed for bisphenol-A, alkylphenols and alkylphenol ethoxylates, phthalates, flame retardants and synthetic musk compounds. The results clearly indicated the presence of these compounds in precipitation. The concentrations ranged from the low ng l(-1) range for flame retardants to several thousands of ng l(-1) for the phthalates. Bisphenol-A was found in 30% of the samples in concentrations up to 130 ng l(-1), while alkylphenols and alkylphenol ethoxylates were found in virtually all locations in concentrations up to 920 ng l(-1) for the individual compounds. Phthalates were by far the most abundant xeno-estrogens in the precipitation samples and were found in every sample. Di-isodecyl phthalate was found in a surprisingly high concentration of almost 100 000 ng l(-1).

Flax is a food and dietary supplement commonly used for menopausal symptoms. Flax is known for its lignan, α-linolenic acid, and fiber content, components that may possess phytogestrogenic, anti-inflammatory, and hormone modulating effects, respectively. We conducted a systematic review of flax for efficacy in improving menopausal symptoms in women living with breast cancer and for potential impact on risk of breast cancer incidence or recurrence. Methods. We searched MEDLINE, Embase, the Cochrane Library, and AMED from inception to January 2013 for human interventional or observational data pertaining to flax and breast cancer. Results. Of 1892 records, we included a total of 10 studies: 2 randomized controlled trials, 2 uncontrolled trials, 1 biomarker study, and 5 observational studies. Nonsignificant (NS) decreases in hot flash symptomatology were seen with flax ingestion (7.5 g/d). Flax (25 g/d) increased tumor apoptotic index (P < .05) and decreased HER2 expression (P < .05) and cell proliferation (Ki-67 index; NS) among newly diagnosed breast cancer patients when compared with placebo. Uncontrolled and biomarker studies suggest beneficial effects on hot flashes, cell proliferation, atypical cytomorphology, and mammographic density, as well as possible anti-angiogenic activity at doses of 25 g ground flax or 50 mg secoisolariciresinol diglycoside daily. Observational data suggests associations between flax and decreased risk of primary breast cancer (adjusted odds ratio [AOR] = 0.82; 95% confidence interval [CI] = 0.69-0.97), better mental health (AOR = 1.76; 95% CI = 1.05-2.94), and lower mortality (multivariate hazard ratio = 0.69; 95% CI = 0.50-0.95) among breast cancer patients. Conclusions. Current evidence suggests that flax may be associated with decreased risk of breast cancer. Flax demonstrates antiproliferative effects in breast tissue of women at risk of breast cancer and may protect against primary breast cancer.

An endocrine disruptor is an exogenous substance that causes adverse health effects in an intact organism or its progeny, secondary to changes in endocrine function. Endocrine disruptors of widely diverse chemical structures that have oestrogenic properties are known as oestrogenic xenobiotics or xenoestrogens. Some of these substances, such as phytoestrogens and mycoestrogens, can come from diet or from the environment. Although the oestrogenic activity of these substances is weaker than that of oestradiol, new chemicals with endocrine disrupting potential continue to be discovered, inadvertent forms of exposure are constantly being identified, and there is increasing concern about cumulative effects. Studies in the 1960s and 1970s characterized the oestrogenicity of a number of industrial compounds and the pesticides o,p-DDT, kepone, methoxychlor, phenolic derivatives and polychlorinated biphenyls (PCBs). In the last 5 years, several environmental chemicals have been added to the list of xenoestrogens, including the pesticides toxaphene, dieldrin and endosulphan, and several different compounds used in the food industry, antioxidants such a t-butylhydroxyanisole; plasticizers such as benzylbutylphthalate and 4-OH-alkylphenols; and substances used in dental restorations, such as bisphenol-A. The relevance of these newly discovered endocrine disruptors to human health is now starting to emerge. The few studies that have investigated their effect in humans point in the same direction: if there is indeed an association between exposure to substances with hormone-disruptive activity and certain disorders of endocrine organs, the incidence of such disorders would be greater in areas where exposure to agents with this activity is high. A closer scrutiny is required to determine whether these newly discovered endocrine disrupting chemicals contribute, together with oestrogenic pesticides, to the exposure of humans to xenoestrogens.", "title": "Inadvertent exposure to xenoestrogens." }, { "docid": "MED-5116", "text": "BACKGROUND: Laboratory research and a growing number of epidemiologic studies have provided evidence for a reduced risk of breast cancer associated with dietary intake of certain classes of flavonoids.

The dietary intake of lignan from flax seed gets converted to enterolactone (EL) and enterodiol in the human system. Here we show that the enterolactone has a very significant anti-metastatic activity as demonstrated by its ability to inhibit adhesion and invasion and migration in MCF-7 and MDA MB231 cell lines. MATERIALS AND METHODS: Migration inhibition assay, actin-based cell motility assay along with reverse transcriptase polymerase chain reaction (RT-PCR) for MMP2, MMP9, MMP11 and MMP14 genes were performed in MCF-7 and MDA MB 231 cell lines. RESULTS: Enterolactone seems to inhibit actin-based cell motility as evidenced by confocal imaging and photo documentation of cell migration assay. The results are supported by the observation that the enterolactone in vitro significantly down-regulates the metastasis-related metalloproteinases MMP2, MMP9 and MMP14 gene expressions. No significant alteration in the MMP11 gene expression was found. CONCLUSIONS: Therefore we suggest that the anti-metastatic activity of EL is attributed to its ability to inhibit cell adhesion, cell invasion and cell motility. EL affects normal filopodia and lamellipodia structures, polymerization of actin filaments at their leading edges and thereby inhibits actin-based cell adhesion and cell motility.

Recent cellular, epigenetic and microarray studies are beginning to decipher genistein effects that occur at dietarily relevant low concentrations.

Compared to the control arm, 6 CAFs—including pro-angiogenic factors (stromal-cell derived-1α and myeloid factors (granulocyte-colony-stimulating factor, macrophage colony-stimulating factor — all decreased in the LF arm compared to controls; 3 and 4 CAFs changed in the FS and FS+LF arms, respectively. Weight loss occurred in the LF arms and significantly correlated with VEGF decreases (P <0.001). The CAFs that changed in the LF arm are all known to be regulated by nuclear factor-kappa B (NF-κB), and a pathway analysis identified NF-κB as the most likely regulatory network associated with these changes in the LF arm, but not in the FS-containing arms. These results suggest that a low-fat diet without flaxseed may reduce levels of specific inflammatory cytokines and angiogenic factors and suggests that the NF-κB pathway may be a mediator of these changes.", "title": "Effect of Low-fat Diets on Plasma Levels of NFκB-regulated Inflammatory Cytokines and Angiogenic Factors in Men with Prostate Cancer" }, { "docid": "MED-3843", "text": "PURPOSE: Phytoestrogens are plant-derived, non-steroidal phytochemicals with anticarcinogenic potential.

In addition, changes in metabolism of endogenous hormones, cross-talk between genomic and nongenomic pathways, cross talk with estrogen receptors after binding on other receptors, interference with feedback regulation and neuroendocrine cells, changes in DNA methylation or histone modifications, and genomic instability by interference with the spindle figure can play a role.

Weighted regression of logit-transformed prevalence and sensitization rates were used to evaluate the effects of the year of survey, age, and degree of urbanization. We also analyzed the relationship between prevalence and sensitization rate. RESULTS: Thirty-eight reports with 27 subgroups for prevalence and 134 subgroups for sensitization rate were selected from the literature published in the years between 1986 and 2000.

Risk of breast cancer recurrence, measured by hazard ratios (HR) and 95% confidence intervals (CI), was estimated using multivariable delayed-entry Cox proportional hazards models. Results Suggestive trends for a reduced risk of cancer recurrence were observed with increasing quintiles of daidzein and glycetin intake compared to no intake among postmenopausal women (P for trend: P = .08 for daidzein, P = .06 for glycetin) and among tamoxifen users (P = .10 for daidzein, P = .05 for glycetin).

Cell viability was measured by the propidium iodide nuclei staining fluorometric assay with each assay performed in triplicate. RESULTS: At 10-100 microM, EL significantly inhibited the growth of all cell lines, whereas ED only inhibited PC-3 and LNCaP cells. While EL was a more potent growth inhibitor than ED, both were less potent than genistein. The dose for 50% growth inhibition of LNCaP cells (IC50) by EL was 57 microM, whereas IC50 was 100 microM for ED, (the observed IC50 for genistein was 25 microM).

The baseline and follow-up levels of prostate-specific antigen were 8.1 +/- 5.2 ng/mL and 8.5 +/- 7.7 ng/mL, respectively, for the entire sample (P = 0.58); however, among men with Gleason sums of 6 or less (n = 19), the PSA values were 7.1 +/- 3.9 ng/mL and 6.4 +/- 4.1 ng/mL (P = 0.10).

However, a newer concept of the function of vitamins in nutrition has taken them beyond simply prevention of deficiency symptoms. This concept considers that many vitamins, when taken in relatively large doses, have important functions beyond preventing deficiencies. Linus Pauling was instrumental in putting forward this concept, particularly for vitamin C. Thus, relatively high intakes of vitamins, and in particular vitamins C and E which are antioxidants, are considered to be healthy for the human population. This may be true in some special situations such as, for instance, the prevention of Alzheimer's disease progression.

In fact, vitamin supplementation may be even detrimental and reduce life span. A new concept that we would like to put forward is that nutrients up-regulate the endogenous antioxidant defences. This is particularly true in the case of phytoestrogens for example, which bind to oestrogen receptors and eventually up-regulate the expression of antioxidant genes.

Another compound of interest is the fungicide vinclozolin, which also causes hypospadias in the mouse and rat and can occur concurrently with genistein in the diet as a residue on exposed foods. A study in the United Kingdom found no relationship between a maternal organic vegetarian diet and hypospadias frequency, but women who consumed nonorganic vegetarian diets had a greater percentage of sons with hypospadias. Because nonorganic diets can include residues of pesticides such as vinclozolin, we sought to assess the interaction of realistic daily exposures to genistein and vinclozolin and their effects on the incidence of hypospadias. METHODS: Pregnant mice were fed a soy-free diet and orally gavaged from gestational days 13 to 17 with 0.17 mg/kg/day of genistein, 10 mg/kg/day of vinclozolin, or genistein and vinclozolin together at the same doses, all in 100 microL of corn oil.

Among European countries, higher legume consumption is observed around the Mediterranean, with per capita daily consumption between 8 and 23 g, while in Northern Europe, the daily consumption is less than 5 g per capita.

BACKGROUND: Early and intensive statin therapy in ACS was shown to reduce cardiovascular morbidity and mortality. Utilization and predictors of LLT among hospitalized ACS patients are not known. METHODS: The GWTG database was analyzed for ACS-related hospitalizations from 2005 to 2009. The use of LLT (defined as dose of statin or combination therapy likely to produce>50% reductions in low-density lipoprotein [LDL]) and less intensive LLT at discharge was assessed. Baseline characteristics and temporal trends in LLT were compared in these 2 treatment groups. RESULTS: Of 65,396 patients receiving LLT, only 25,036 (38.3%) were treated with an LLT regimen. Mean total cholesterol, LDL, and triglycerides were significantly higher in the LLT group. Even among those with LDL>130 mg/dL, 50% or less received LLT. Predictors of LLT at discharge included LLT before admission, hyperlipidemia, prior coronary artery disease, increasing body mass index, and in-hospital percutaneous coronary intervention. Although there was some temporal improvement in the rate of LLT from 2005 to 2007, a decline in use of LLT was noted in 2008 and 2009. This was attributed to a sharp reduction in use of ezetimibe in combination with statin, without corresponding increases in intensive statin monotherapy.

Generally, the tax rate for PFIC is very high, so that if any of your stocks are classified as PFIC - you'd better talk to a professional tax adviser (EA/CPA licensed in your State) about how to deal with them. Non-PFIC stocks are dealt with the same as if they were in the US, unless you match certain criteria described in the instructions to form 5471 (then a different set of rules apply, talk to a licensed tax adviser).

Investing in Gold is an indirect investment in the Economy and GDP of the nation of India. To that extent is it only a hedge against inflation, so long as the indian economy grows at a more rapid rate than your local inflation rate. Fact, India currently consumes more than 1/3 of gold production, predominantly in the form of Jewelry. And their demand has been growing rapidly, up 69% just between 2009 and 2010 alone. I can't find too many historial consumption numbers for India, but when you look at past articles on this subject, you see phrases like 'one forth' and '20%' being used only a few years go to describe India's consumption levels. Fact, India has virtually no domestic sources of gold. India’s handful of gold mines produce about 2.5 tonnes of the metal each year, a fraction of the country’s annual consumption of about 800 tonnes. Fact. Indian Culture places high value on gold as a visible demonstration of wealth. Particularly in situations such In Indian weddings where the bride brings in gold to show her family's status and wealth and it forms part of the dowry given to bride. It is believed that a bride wearing 24k gold on their wedding to bring luck and happiness throughout the married life. Fact, the recent trends in outsourcing, Indian citizens working abroad sending money home, etc have all lead to a influx of foreign cash to the Indian economy and explosive GDP growth. See the following chart and compare the period of 2000-current with a chart showing the price of gold in other answer here. Notice how the curves parallel each other to a large degree Potentially unfounded conclusion drawn from above numbers. The rapid growth of the Indian economy, coupled with a rich cultural tradition that values gold as a symbol of wealth, along with a sudden rise in 'wealthy' people due to the economy and influx of foreign cash, has resulted in skyrocketing demand for gold from India, and this large 'consumption' demand is the most likely explanation for the sudden rise in the price of gold over the last several years. Investors then jump on the 'rising price bandwagon' as especially does anyone that can make a profit from selling gold to those seeking to get on said bandwagon. As such, as long as indian cultural tradition remains unchanged, and their economy remains strong, the resulting increasing demand for gold will sustain current and perhaps increased prices. Should there be any sudden collapse in the Indian GDP, gold will likely tumble in parallel. disclaimer: not an expert, just observations based off the data I've seen, there may be other parts to the picture of 'gold demand' that I've not considered.", "title": "" }, { "docid": "146557", "text": "What are the steps to bring the money to the US?

Your bank will have forms for completion of this process.

Now, with regard to your question, NRIs are entitled to make deposits into NRO accounts as well as NRE (NonResident External) accounts. The differences are that money deposited into an NRE account, though converted to Indian Rupees, can be converted back very easily to foreign currency if need be. However, the re-conversion is at the exchange rate then in effect, and you may well lose that 10% interest earned because of a change in exchange rate.

In vitro studies showed that MCF 7 with wild type p53 was more sensitive to TPL than T 47 D, which is p53 negative. TPL induced loss of cell viability was determined by MTT assay. After 72h incubation, the IC 50 values for MCF 7 was found to be approximately 8microg/ml and that for T 47 D was approximately 26microg/ml. Moreover, TPL inhibited the clonogenic growth of MCF 7 cells, which was significantly recovered by pifithrin-alpha, the p53 inhibitor. However, pifithrin-alpha, did not modify TPL induced cytotoxicity in T 47 D cells. Exogenous addition of antioxidants, glutathione (GSH) and N-Acetyl-Cysteine (NAC) inhibited the anti-proliferative ability of TPL in both MCF 7 and T47 D. Annexin-V and propidium iodide double staining of cells treated with TPL for 2h revealed that TPL induced significant apoptosis in both the cell lines in a dose dependant manner but magnitude of apoptosis was significantly higher in MCF 7 than in T 47-D cells. TPL was also found to induce dose and time dependent increase in intracellular reactive oxygen species in both the cell lines. Present results have demonstrated that MCF 7 and T 47 D cells exhibited differential sensitivity to TPL, which seems to be dependant on their p53 status. Inhibition of anti-proliferative ability of TPL by antioxidants suggests a role for TPL induced ROS in the induction of apoptosis.

On the other hand, treatment of normal breast epithelial cells, MCF-10 F, human peripheral blood mononuclear cells, mouse liver and spleen cells, with similar concentrations of Triphala did not affect their cytotoxicity significantly. The drug treatment was found to induce apoptosis in MCF-7 and barcl-95 cells in vitro as determined by annexin-V fluorescence and proportion of apoptotic cells was found dependent on Triphala concentration. MCF-7 cells treated with Triphala when subjected to single cell gel electrophoresis, revealed a pattern of DNA damage, characteristic of apoptosis. Studies on Triphala treated MCF-7 and barcl-95 cells showed significant increase in intracellular reactive oxygen species (ROS) in a concentration dependent manner. ROS increase was, however, found to be insignificant in MCF-10 F as well as in murine spleen and liver normal cells. In vivo, direct oral feeding of Triphala to mice (40 mg/kg body weight) transplanted with barcl-95 produced significant reduction in tumor growth as evaluated by tumor volume measurement. It was also found that apoptosis was significantly higher in the excised tumor tissue of Triphala fed mice as compared to the control, suggesting the involvement of apoptosis in tumor growth reduction. These results suggest that Triphala possessed ability to induce cytotoxicity in tumor cells but spared the normal cells. The differential effect of Triphala on normal and tumor cells seems to be related to its ability to evoke differential response in intracellular ROS generation.

[ { "docid": "MED-3852", "text": "Recently two groups of compounds with diphenolic structure, the lignans and the isoflavonic phytoestrogens, were detected and identified in human urine and other biological fluids. These compounds are of great biological interest because they exhibit both in vitro and in vivo weak estrogenic and sometimes also antiestrogenic activities and many plant lignans have been shown to have anticarcinogenic, antiviral, antifungal and other interesting biological effects. The compounds found in relatively large amounts (10-1000 times more than estrogens) in urine are modified by intestinal bacteria from plant lignans and phytoestrogens, which are present in fiber-rich food such as grain and beans. They bind with low affinity to estrogen receptors and preliminary results suggest that they may induce production of sex hormone binding globulin (SHBG) in the liver and in this way may influence sex hormone metabolism and biological effects. Five compounds, the lignans enterolactone (Enl), enterodiol (End) and the isoflavonic phytoestrogen metabolites daidzein (Da), equol (Eq) and O-desmethylangolensin (O-Dma) were measured in urine by gas chromatography-mass spectrometry (selected ion monitoring) using deuterated internal standards in 5 groups of women (total number 53). The members of three dietary groups (omnivores, lactovegetarians and macrobiotics) were living in Boston and of two groups in Helsinki (omnivores and lactovegetarians). Until now measurements have been carried out in 94 72-h samples. The highest mean excretion of the most abundant compound, enterolactone, was found in the macrobiotic group and the lowest in the omnivoric groups. Total mean 24-h excretion of enterolactone was 17,680 nmol in the macrobiotics, 4,170 nmol in the Boston lactovegetarians, 3,650 nmol in the Helsinki lactovegetarians, 2,460 nmol in the Helsinki omnivores and 2,050 nmol in the Boston omnivores. The other diphenols followed approximately the same pattern. In an earlier study the lowest excretion of enterolactone (1,040 nmol/24 h) was found in a group of postmenopausal apparently healthy breast cancer patients living in Boston.

Evidence in the scientific literature of the funding effect--the close correlation between the results of a study desired by a study's funder and the reported results of that study--suggests that the financial interest of a study's sponsors should be taken into account when considering the study's findings.

This review presents milk as a materno-neonatal relay system functioning by transfer of preferential amino acids, which increase plasma levels of glucose-dependent insulinotropic polypeptide (GIP), glucagon-like peptide-1 (GLP-1), insulin, growth hormone (GH) and insulin-like growth factor-1 (IGF-1) for mTORC1 activation.

It was hypothesized that wild rice from north-central Wisconsin could potentially have elevated concentrations of some heavy metals because of possible exposure to these elements from the atmosphere or from water and sediments. In addition, no studies of heavy metals in wild rice from Wisconsin had been performed, and a baseline study was needed for future comparisons. Wild rice plants were collected from four areas in Bayfield, Forest, Langlade, Oneida, Sawyer and Wood Counties in September, 1997 and 1998 and divided into four plant parts for elemental analyses: roots, stems, leaves and seeds. A total of 194 samples from 51 plants were analyzed across the localities, with an average of 49 samples per part depending on the element. Samples were cleaned of soil, wet digested, and analyzed by ICP for Ag, As, Cd, Cr, Cu, Hg, Mg, Pb, Se and Zn. Roots contained the highest concentrations of Ag, As, Cd, Cr, Hg, Pb, and Se. Copper was highest in both roots and seeds, while Zn was highest just in seeds. Magnesium was highest in leaves. Seed baseline ranges for the 10 elements were established using the 95% confidence intervals of the medians. Wild rice plants from northern Wisconsin had normal levels of the nutritional elements Cu, Mg and Zn in the seeds.

Numerous mechanisms may underlie these associations such as favorable effects of flavanols on blood pressure, platelet aggregation, thrombosis, inflammation, and the vascular endothelium. The brachial artery flow-mediated dilation (FMD) technique has emerged as a robust method to quantify endothelial function in humans. Collectively, the preponderance of evidence indicates that FMD is a powerful surrogate measure for firm cardiovascular endpoints, such as cardiovascular-related mortality, in humans. Thus, literally thousands of studies have utilized this technique to document group differences in FMD, as well as to assess the effects of various interventions on FMD. In regards to the latter, numerous studies indicate that both acute and chronic ingestion of cocoa/chocolate increases FMD in humans. Increases in FMD after cocoa/chocolate ingestion appear to be dose-dependent such that greater increases in FMD are observed after ingestion of larger quantities. The mechanisms underlying these responses are likely diverse, however most data suggest an effect of increased nitric oxide bioavailability.

Tissue inhibitors of MMPs (TIMPs) are well-known for their ability to inhibit MMP activity thereby inhibiting malignant progression. Inositol hexaphosphate (IP6 phytic acid) has been recognized to have both preventive and therapeutic effects against various cancers including that of colon. In in vitro studies, IP6 has been demonstrated to inhibit cancer cell adhesion and migration. In the present study, the effect of IP6 on the expression of MMP and TIMP genes was evaluated in unstimulated and IL-1β-stimulated colon cancer cell line Caco-2. Materials and methods Real-time QRT-PCR was used to validate the transcription level of selected MMP and TIMP genes in Caco-2 cells after treatment with 1 ng/ml of IL-1β, 2.5 mM of IP6, and both for 6, 12, and 24 h. Results Stimulation of cells with IL-1β only resulted in an overexpression of MMP and their TIMP mRNAs. A significant decrease in MMP-13, MMP-3, MMP-2, and TIMP-1 basal expression was achieved by IP6. IP6 was also an efficient downregulator of MMP-1, MMP-9, and TIMP-2 genes transcription stimulated by IL-1β in 6 h lasting culture. After 12 h, IL-1β-induced MMP-2 mRNA expression was significantly reduced by IP6. Conclusion Proinflammatory cytokine IL-1β upregulates MMP and TIMP mRNAs expression in colon cancer epithelial cells Caco-2. IP6 (2.5 mM) influences constitutive expression of both MMP and TIMP genes and downregulates IL-1β stimulated transcription of some of these genes.

High-sensitivity CRP (hs-CRP) and markers of insulin resistance (IR), homeostasis model assessment-IR, quantitative insulin-sensitivity check index and fasting glucose to insulin ratio were evaluated in each patient. RESULTS: A total of 10 subjects did not complete the trial (three patients in the Metformin group and seven patients in the diet group) and a total of 30 subjects completed the trial (17 subjects in the Metformin group and 13 subjects in the diet group). Serum concentration of hs-CRP significantly decreased in both the Metformin (5.29 ± 2.50 vs 3.81 ± 1.99, P = 0.008) and diet groups (6.08 ± 2.14 vs 4.27 ± 1.60, P = 0.004). There were no significant differences in mean hs-CRP decrement between the two groups. Decrease in hs-CRP levels was significantly correlated with waist circumference in the diet group (r = 0.8, P < 0.001). The effect of a hypocaloric diet with 5-10% weight reduction on markers of insulin resistance (homeostasis model assessment-IR, fasting glucose to insulin ratio, quantitative insulin-sensitivity check index) was better than Metformin therapy (P = 0.001).

Patients, in fact, if not directly questioned, tend to scarcely report them. The aim of the present meta-analysis was to quantify SD caused by antidepressants on the basis of studies where sexual functioning was purposely investigated through direct inquiry and specific questionnaires. METHODS: A literature search was conducted using MEDLINE, ISI Web of Knowledge, and references of selected articles. Selected studies performed on patients without previous SD were entered in the Cochrane Collaboration Review Manager (RevMan version 4.2). Our primary outcome measure was the rate of total treatment-emergent SD. Our secondary outcome measures were the rates of treatment-emergent desire, arousal, and orgasm dysfunction. RESULTS: Our analyses indicated a significantly higher rate of total and specific treatment-emergent SD and specific phases of dysfunction compared with placebo for the following drugs in decreasing order of impact: sertraline, venlafaxine, citalopram, paroxetine, fluoxetine, imipramine, phenelzine, duloxetine, escitalopram, and fluvoxamine, with SD ranging from 25.8% to 80.3% of patients. No significant difference with placebo was found for the following antidepressants: agomelatine, amineptine, bupropion, moclobemide, mirtazapine, and nefazodone. DISCUSSION: Treatment-emergent SD caused by antidepressants is a considerable issue with a large variation across compounds. Some assumptions, such as the inclusion of open-label studies or differences in scales used to assess SD, could reduce the significance of our findings.

METHODS: Analysis of major tobacco industries' internal secret documents on cigarette radioactivity made available online by the Master Settlement Agreement in 1998. RESULTS: The documents show that the industry was well aware of the presence of a radioactive substance in tobacco as early as 1959. Furthermore, the industry was not only cognizant of the potential \"cancerous growth\" in the lungs of regular smokers but also did quantitative radiobiological calculations to estimate the long-term (25 years) lung radiation absorption dose (rad) of ionizing alpha particles emitted from the cigarette smoke. Our own calculations of lung rad of alpha particles match closely the rad estimated by the industry. According to the Environmental Protection Agency, the industry's and our estimate of long-term lung rad of alpha particles causes 120-138 lung cancer deaths per year per 1,000 regular smokers. Acid wash was discovered in 1980 to be highly effectively in removing (210)Po from the tobacco leaves; however, the industry avoided its use for concerns that acid media would ionize nicotine converting it into a poorly absorbable form into the brain of smokers thus depriving them of the much sought after instant \"nicotine kick\" sensation.

Recently, however, evidence has been accumulating to suggest that dietary cholesterol is less relevant to cardiovascular risk than dietary saturated fat. This randomized controlled crossover trial was conducted to determine the effects of egg ingestion on endothelial function, a reliable index of cardiovascular risk. METHODS: Forty-nine healthy adults (mean age 56 years, 40% females) underwent a baseline brachial artery reactivity study (BARS), and were assigned to two eggs or oats daily for 6 weeks in random sequence with a 4-week washout. A BARS was done at the end of each treatment phase, measuring flow-mediated vasodilation (FMD) in the brachial artery using a high-frequency ultrasound. RESULTS: FMD was stable in both egg and oat groups, and between-treatment differences were not significant (egg -0.96%, oatmeal -0.79%; p value >0.05). Six weeks of egg ingestion had no effect on total cholesterol (baseline: 203.8 mg/dl; post-treatment: 205.3) or LDL (baseline: 124.8 mg/dl; post-treatment: 129.1).

The most consistent protective effects were observed for higher levels--dietary intake, serum, plasma, or urinary metabolites--of β-carotene and renal cell cancer, β-cryptoxanthin and lung cancer, isothiocyanates and lung cancer, isothiocyanates and gastrointestinal cancer, lignans and postmenopausal breast cancer, and flavonoids and lung cancer. Although elevated risk of certain cancers with higher levels of certain phytochemicals was observed, an insufficient pool of studies examining the same associations or inconsistent findings across studies limit the ability to conclude that any one phytochemical increases cancer risk.

Importantly, continued research efforts are needed to evaluate the cumulative and interactive effects of numerous phytochemicals and phytochemical-rich foods on cancer risk.", "title": "Phytochemicals and cancer risk: a review of the epidemiological evidence." }, { "docid": "MED-1193", "text": "Summary Background Statins reduce LDL cholesterol and prevent vascular events, but their net effects in people at low risk of vascular events remain uncertain. Methods This meta-analysis included individual participant data from 22 trials of statin versus control (n=134 537; mean LDL cholesterol difference 1·08 mmol/L; median follow-up 4·8 years) and five trials of more versus less statin (n=39 612; difference 0·51 mmol/L; 5·1 years). Major vascular events were major coronary events (ie, non-fatal myocardial infarction or coronary death), strokes, or coronary revascularisations. Participants were separated into five categories of baseline 5-year major vascular event risk on control therapy (no statin or low-intensity statin) (<5%, ≥5% to <10%, ≥10% to <20%, ≥20% to <30%, ≥30%); in each, the rate ratio (RR) per 1·0 mmol/L LDL cholesterol reduction was estimated. Findings Reduction of LDL cholesterol with a statin reduced the risk of major vascular events (RR 0·79, 95% CI 0·77–0·81, per 1·0 mmol/L reduction), largely irrespective of age, sex, baseline LDL cholesterol or previous vascular disease, and of vascular and all-cause mortality. The proportional reduction in major vascular events was at least as big in the two lowest risk categories as in the higher risk categories (RR per 1·0 mmol/L reduction from lowest to highest risk: 0·62 [99% CI 0·47–0·81], 0·69 [99% CI 0·60–0·79], 0·79 [99% CI 0·74–0·85], 0·81 [99% CI 0·77–0·86], and 0·79 [99% CI 0·74–0·84]; trend p=0·04), which reflected significant reductions in these two lowest risk categories in major coronary events (RR 0·57, 99% CI 0·36–0·89, p=0·0012, and 0·61, 99% CI 0·50–0·74, p<0·0001) and in coronary revascularisations (RR 0·52, 99% CI 0·35–0·75, and 0·63, 99% CI 0·51–0·79; both p<0·0001). For stroke, the reduction in risk in participants with 5-year risk of major vascular events lower than 10% (RR per 1·0 mmol/L LDL cholesterol reduction 0·76, 99% CI 0·61–0·95, p=0·0012) was also similar to that seen in higher risk categories (trend p=0·3). In participants without a history of vascular disease, statins reduced the risks of vascular (RR per 1·0 mmol/L LDL cholesterol reduction 0·85, 95% CI 0·77–0·95) and all-cause mortality (RR 0·91, 95% CI 0·85–0·97), and the proportional reductions were similar by baseline risk. There was no evidence that reduction of LDL cholesterol with a statin increased cancer incidence (RR per 1·0 mmol/L LDL cholesterol reduction 1·00, 95% CI 0·96–1·04), cancer mortality (RR 0·99, 95% CI 0·93–1·06), or other non-vascular mortality. Interpretation In individuals with 5-year risk of major vascular events lower than 10%, each 1 mmol/L reduction in LDL cholesterol produced an absolute reduction in major vascular events of about 11 per 1000 over 5 years. This benefit greatly exceeds any known hazards of statin therapy. Under present guidelines, such individuals would not typically be regarded as suitable for LDL-lowering statin therapy. The present report suggests, therefore, that these guidelines might need to be reconsidered.

If you deducted this last year, then you need to add in any amount that you received in state income tax refunds last year to your taxes this year, to make up for the fact that you ended up deducting more state income tax than was really due to the state. If you took the standard deduction last year instead of itemizing, then you didn't deduct your state income tax withholding last year and you don't need to claim your refund as income this year. Also, if you itemized, but chose to take the state sales tax deduction instead of the state income tax deduction, you also don't need to add in the refund as income. For whatever reason, Illinois decided that you don't get a 1099-G. It might be that the amount of the refund was too small to warrant the paperwork. It might be that they screwed up. But if you deducted your state income tax withholding on last year's tax return, then you need to add the state tax refund you got last year on line 10 of this year's 1040, whether or not the state issued you a form or not.

This may have been simpler from their perspective if the broker fees were variable, or integrated, or unknown for a number of clients party to a transaction.

If the CEO is talking about 1099 it means he's going to hire you as a contractor which contradicts the statement about equity allocation. That's an entirely different situation. 1) Specifically, would the 1099-MISC form be used in this case? 1099-MISC is used to describe various payments. Depending on which box is filled, the tax treatment may be as of employment income (subject to SE taxes) or passive income (royalties, rents, etc - subject to various limitations in the tax code). 3) If this is the only logical method of compensation (receiving a % of real estate sales), how would it be taxed? That would probably be a commission and taxed as employment income. I suggest to get a professional tax adviser consultation on this issue, with specific details, numbers, and kinds of deals involved. You can get gain or lose a lot of money just because you're characterized as a contractor and not LLC member or employee (each has its own benefits and disadvantages, and you have to consider them all). 4) Are there any advantages/disadvantages to acquiring and selling properties through the company as opposed to receiving a % of sales?

Next, they couldn't have just created an IRA out of thin air and moved some money into it without some paperwork and signatures from you, so you should have copies of that paperwork. Principal may also still have archived copies of that paperwork, that they may be able to provide to you, although they'll probably charge for that service. Also, there would have been tax reporting around the rollover. For the year the rollover occurred in, you would have received a 1099-R and 5498. The 1099-R would have to have been reported on your federal (and possibly state) income tax for that year. It may be possible to obtain copies of old 1099-R's from the IRS, maybe call them and ask. In subsequent years, you should have received at least a year-end statement. If you don't have any of that, and contacting Principal and the IRS don't help, then I'm not sure there's much that anyone can do to help you. As far as I know, there's no \"\"universal clearinghouse\"\" for IRAs, and there are a lot of IRA custodians.

They may be reluctant to do that because some people believe that could trigger an IRS audit. The reason is that independent contractor vs employee is supposed to be defined by your job function, not by your choice. If you were a contractor and then switched to be an employee without changing your job description, then the IRS could claim that you should have always been an employee the entire time, and so should every one of the other contractors that work for that company with a similar job function. It's a hornet's nest that the employer may not want to poke. But that's not your problem; what should you do about it? When you say \"\"he added my Federal and FICA W/H together\"\", do you mean that total appears in box 4 of your 1099? If so, it sounds like the employer is expecting you to re-pay the employer portion of FICA. Can you ask them if they actually paid it? If they did, then I don't see them having a choice but to issue a W2, since the IRS would be expecting one. If they didn't pay your FICA, then the amount this will cost you is 7.65% of what would have been your W2 wages. IMHO it would be reasonable for you to request that they send you a check for that extra amount. Note: even though that amount will be less than $600 and you won't receive a 1099 in 2017 for it, legally you'll still have to pay tax on that amount so I think a good estimate would be to call it 10% instead.

You start off as a contractor, and later convert to an employee. In order to avoid issuing a 1099 and W2 to the same person in a single tax year, companies typically utilize one of the following strategies: Your particular situation is closest to situation 2, but the reverse. Instead of retroactively calling you a W2 employee the entire time, your employer is cheating and attempting to classify you as a 1099 contractor the entire time. This is frowned upon by the IRS, as well as the employee since as you discovered it costs you more money in the form of employer FICA. From your description it sounds like your employer was trying to do you a favor and didn't quite follow through with it.

That's generally where I start to figure out where to report what. The section on Royalties has this to say: Royalties from copyrights, patents, and oil, gas, and mineral properties are taxable as ordinary income. In most cases, you report royalties in Part I of Schedule E (Form 1040). However, if you hold an operating oil, gas, or mineral interest or are in business as a self-employed writer, inventor, artist, etc., report your income and expenses on Schedule C or Schedule C-EZ (Form 1040). It sounds like you are receiving royalties from a copyright, and not as a self-employed writer. That means that you would report the income on Schedule E, Part I. I've not used Schedule E before, but looking at the instructions for it, you enter this as \"\"Royalty Property\"\". For royalty property, enter code “6” on line 1b and leave lines 1a and 2 blank for that property. So, in Line 1b, part A, enter code 6. (It looks like you'll only use section A here as you only have one royalty property.) Then in column A, Line 4, enter the royalties you have received. The instructions confirm that this should be the amount that you received listed on the 1099-MISC. Report on line 4 royalties from oil, gas, or mineral properties (not including operating interests); copyrights; and patents. Use a separate column (A, B, or C) for each royalty property. If you received $10 or more in royalties during 2016, the payer should send you a Form 1099-MISC or similar statement by January 31, 2017, showing the amount you received. Report this amount on line 4. I don't think that there's any relevant Expenses deductions you could take on the subsequent lines (though like I said, I've not used this form before), but if you had some specific expenses involved in producing this income it might be worth looking into further.

If this is the case, then each partnership would need to file form K-1 and issue a copy to the partners of that partnership. I think, but I'm not sure, that each partnership would need an Employer Identification Number (EIN; you can apply for and receive these online with the IRS). You would only pay tax on the portion of profits that are assigned to you on the K-1. (If you've accidentally created a partnership without thinking through all the ramifications, you probably want to straighten this out. You can be held liable for the actions of your partners.) On the other hand, if your contract with Bob explicitly makes you a contractor and not a partner, then Bob should probably be issuing a 1099 to you. Similarly for you and Joe -- if your contract with Joe makes him a subcontractor, then you may need to get an EIN and issue him a 1099 at the end of the year. The money you pay to Joe is a business expense, and would be deducted from the profits you show on your Schedule C. In my opinion, it would be worth the $200 fee paid to a good CPA to make sure you get this right.", "title": "" }, { "docid": "77245", "text": "Careful. I would personally need a LOT more than $5 more per hour to go from W-2 employment to 1099 employment. It boils down to two reasons: (1) employers pay a huge amount of taxes on behalf of their employees, and (2) you would have to pay all of your own withholding up front. Your current proposal from them doesn't account for that. There are also risks that you face as a 1099. On the first item, your employer currently pays 6.2% of your Social Security tax. You pay the other 6.2%. If you go to 1099 status, you will be self-employed as an independent contractor and have to pay the full 12.4% out of your increased 1099 wages. On the second item, your employer also does your withholding out of your paychecks based on what you tell them on a form W-4. If you're disciplined enough to pay this out yourself in estimated taxes every time you get a paycheck, great. Many people aren't and just see a much bigger paycheck with no taxes out of it, and end up with a large tax bill at the end of the year. Overall, there are some other considerations like healthcare and other benefits. These will not be available to you as a 1099 employee. You can also be terminated spontaneously, unless you have a specific contract length with the company. As I see it, not including any benefits you would receive, you're looking at LESS money in your pocket at $50/hr as a contractor than at your $48/hr. Your pay net social security deductions is: $48 x 40 hrs x 52 weeks = 99,840 * .938 = 93,649.92. As a 1099 @ $50/hr you would net $50 x 40 hrs x 52 weeks = 104,000 * .876 = 91,104. Then there are the rest of taxes, etc to figure out your real take-home pay. I'm not a tax advisor, but I would be very careful to get the whole picture figured out before jumping.

Here's another way to look at it: Generally, we invest in something, then might leave it there for a few years, then take it out, but don't touch it in between.

Now I have, after one year: X(1)+Y(1)+Z(1) = X(0)*G(1,X) + Y(0)*G(1,Y) + Z(0)*G(1,Z) = ( X(0)+Y(0)+Z(0) ) * \"\"average annual growth\"\" Now, in this case, if we assume X(0) = Y(0) = Z(0) = 1, i.e. I put equal amounts in each, we see that the average annual growth rate we want in this case is the arithmetic mean: arithmetic mean = (G(1,X) + G(1,Y) + G(1,Z)) / 3 (if we had unequal amounts at the beginning, it would be a weighted average).

I suggest asking the clients not to do this to you, since it may cost you significant amounts to fight the IRS later on.

Boyz II Men found fame.
[ { "docid": "Boyz_II_Men", "text": "Boyz II Men is an American R&B vocal group from Philadelphia , Pennsylvania , best known for emotional ballads and acappella harmonies . Formerly a quartet including bass Michael McCary , they are currently a trio composed of baritone Nathan Morris alongside tenors Wanya Morris and Shawn Stockman . During the 1990s , Boyz II Men found fame on Motown Records as a quartet . McCary left the group in 2003 due to health issues and contractual agreements . During the 1990s , Boyz II Men gained international success . This began with the release of the number one single `` End of the Road '' in 1992 , which reached the top of charts worldwide . `` End of the Road '' would set a new record for longevity , staying at number one on the Billboard Hot 100 for thirteen weeks , breaking the decades-old record held by Elvis Presley . Boyz II Men proceeded to break this record with the subsequent releases of `` I 'll Make Love to You '' and `` One Sweet Day '' ( with Mariah Carey ) , which , at fourteen and sixteen weeks respectively , each set new records for the total number of weeks at number one . `` I 'll Make Love to You '' also topped the charts in Australia ( for four weeks ) and garnered international success . As of 2016 , `` One Sweet Day '' still holds the all-time record with sixteen weeks at the top of the Hot 100 . Consequently , Boyz II Men are top ranking members with regard to time spent at number one in Billboard history , ranking in the fourth spot with 50 weeks ( as of 2014 ) . Furthermore , when `` On Bended Knee '' took the number one spot away from `` I 'll Make Love to You '' , Boyz II Men became only the third artists ever ( after The Beatles and Presley ) to replace themselves at the top of the Billboard Hot 100 . Boyz II Men are among a select group of artists that have held at the number-one spot for at least 50 weeks cumulatively , placing them just fourth on that list behind Elvis Presley , The Beatles , and Mariah Carey . These achievements were enough to earn Boyz II Men recognition as Billboard magazine 's fourth most successful musical group of the 1990s . Boyz II Men continue to perform worldwide , as a trio . Their most recent studio album , Collide , was released in 2014 .", "title": "" } ]

SIRT1 and the FOXO transcription factor FOXO3 formed a complex in cells in response to oxidative stress, and SIRT1 deacetylated FOXO3 in vitro and within cells. SIRT1 had a dual effect on FOXO3 function: SIRT1 increased FOXO3's ability to induce cell cycle arrest and resistance to oxidative stress but inhibited FOXO3's ability to induce cell death. Thus, one way in which members of the Sir2 family of proteins may increase organismal longevity is by tipping FOXO-dependent responses away from apoptosis and toward stress resistance.", "title": "Stress-dependent regulation of FOXO transcription factors by the SIRT1 deacetylase." } ]

Upon cold exposure or nutritional abundance, sympathetic neurons stimulate BAT to express Ucp1 to induce energy dissipation and thermogenesis. Accordingly, increased Ucp1 expression reduces obesity in mice and is correlated with leanness in humans. Despite this significance, there is currently a limited understanding of how Ucp1 expression is physiologically regulated at the molecular level. Here, we describe the involvement of Sestrin2 and reactive oxygen species (ROS) in regulation of Ucp1 expression. Transgenic overexpression of Sestrin2 in adipose tissues inhibited both basal and cold-induced Ucp1 expression in interscapular BAT, culminating in decreased thermogenesis and increased fat accumulation. Endogenous Sestrin2 is also important for suppressing Ucp1 expression because BAT from Sestrin2(-/-) mice exhibited a highly elevated level of Ucp1 expression. The redox-inactive mutant of Sestrin2 was incapable of regulating Ucp1 expression, suggesting that Sestrin2 inhibits Ucp1 expression primarily through reducing ROS accumulation. Consistently, ROS-suppressing antioxidant chemicals, such as butylated hydroxyanisole and N-acetylcysteine, inhibited cold- or cAMP-induced Ucp1 expression as well. p38 MAPK, a signaling mediator required for cAMP-induced Ucp1 expression, was inhibited by either Sestrin2 overexpression or antioxidant treatments.

Inhibition of autophagy by chemical compounds or knocking down the expression of key autophagy proteins such as ATG7, ATG8, and receptor interacting protein (RIP) blocks ROS accumulation and cell death. The cause of abnormal ROS accumulation is the selective autophagic degradation of the major enzymatic ROS scavenger, catalase.

Several studies have shown a crucial role for the kinase RIP1 and the adenosine nucleotide translocator (ANT)-cyclophilin D (CypD) complex in necrotic cell death. The underlying mechanism of zVAD-fmk-mediated sensitization to necrotic cell death involves the inhibition of caspase-8-mediated proteolysis of RIP1 and disturbance of the ANT-CypD interaction.

The positive role of RIP1 and the negative role of caspase-8 in both necrotic and autophagic cell death suggest that the pathways of these two types of cell death are interconnected. Necrotic cell death represents a rapid cellular response involving mitochondrial reactive oxygen species (ROS) production, decreased adenosine triphosphate concentration, and other cellular insults, whereas autophagic cell death first starts as a survival attempt by cleaning up ROS-damaged mitochondria.

It provides the mechanical scaffold and environmental cues to cells. Upon cell attachment, the ECM signals into the cells. In this process, reactive oxygen species (ROS) are physiologically used as signalizing molecules. RECENT ADVANCES ECM attachment influences the ROS-production of cells. In turn, ROS affect the production, assembly and turnover of the ECM during wound healing and matrix remodeling. Pathological changes of ROS levels lead to excess ECM production and increased tissue contraction in fibrotic disorders and desmoplastic tumors. Integrins are cell adhesion molecules which mediate cell adhesion and force transmission between cells and the ECM. They have been identified as a target of redox-regulation by ROS. Cysteine-based redox-modifications, together with structural data, highlighted particular regions within integrin heterodimers that may be subject to redox-dependent conformational changes along with an alteration of integrin binding activity. CRITICAL ISSUES In a molecular model, a long-range disulfide-bridge within the integrin β-subunit and disulfide bridges within the genu and calf-2 domains of the integrin α-subunit may control the transition between the bent/inactive and upright/active conformation of the integrin ectodomain. These thiol-based intramolecular cross-linkages occur in the stalk domain of both integrin subunits, whereas the ligand-binding integrin headpiece is apparently unaffected by redox-regulation.

This is probably achieved by an active transportation via mitochondrial melatonin transporter(s). Melatonin protects mitochondria by scavenging reactive oxygen species (ROS), inhibiting the mitochondrial permeability transition pore (MPTP), and activating uncoupling proteins (UCPs). Thus, melatonin maintains the optimal mitochondrial membrane potential and preserves mitochondrial functions. In addition, mitochondrial biogenesis and dynamics is also regulated by melatonin. In most cases, melatonin reduces mitochondrial fission and elevates their fusion.

As expected, we found that human M(diameter)s acidify their phagosomes more efficiently than human DCs. Accordingly, the expression of the vacuolar proton ATPase (V-H(+)-ATPase) was higher in M(diameter)s than in DCs. Phagosomal ROS production, however, was also higher in M(diameter)s than in DCs, due to higher levels of gp91phox expression and recruitment to phagosomes. In contrast, in the absence of active NOX2, the phagosomal and endosomal pH decreased. Both in the presence of a NOX2 inhibitor and in DCs derived from patients with CGD, the cross-presentation of 2 model tumor antigens was impaired.

Chronic oxidative stress has numerous pathological consequences including cancer, arthritis and neurodegenerative disease. Glutathione-associated metabolism is a major mechanism for cellular protection against agents which generate oxidative stress. It is becoming increasingly apparent that the glutathione tripeptide is central to a complex multifaceted detoxification system, where there is substantial inter-dependence between separate component members. Glutathione participates in detoxification at several different levels, and may scavenge free radicals, reduce peroxides or be conjugated with electrophilic compounds. Thus, glutathione provides the cell with multiple defences not only against ROS but also against their toxic products. This article discusses how glutathione biosynthesis, glutathione peroxidases, glutathione S-transferases and glutathione S-conjugate efflux pumps function in an integrated fashion to allow cellular adaption to oxidative stress. Co-ordination of this response is achieved, at least in part, through the antioxidant responsive element (ARE) which is found in the promoters of many of the genes that are inducible by oxidative and chemical stress. Transcriptional activation through this enhancer appears to be mediated by basic leucine zipper transcription factors such as Nrf and small Maf proteins. The nature of the intracellular sensor(s) for ROS and thiol-active chemicals which induce genes through the ARE is described. Gene activation through the ARE appears to account for the enhanced antioxidant and detoxification capacity of normal cells effected by many cancer chemopreventive agents. In certain instances it may also account for acquired resistance of tumours to cancer chemotherapeutic drugs.

Coculture led to increased COX-2 expression in the HCC1954 cells and elevated prostaglandin E(2) levels in conditioned media. Similar results were observed when THP-1 cells were incubated with HCC1937 breast cancer cells or when human monocyte-derived macrophages were cocultured with HCC1954 cells.

METHODS: Mortality was compared with that of the US general population, and with that of a comparison group from the same union. Risk was estimated by standardized mortality ratio, proportional mortality ratio, and directly standardized risk ratio. RESULTS: Poultry workers as a group had an overall excess of deaths from diabetes, anterior horn disease, and hypertensive disease, and a deficit of deaths from intracerebral hemorrhage. Deaths from zoonotic bacterial diseases, helminthiasis, myasthenia gravis, schizophrenia, other diseases of the spinal cord, diseases of the esophagus and peritonitis were non-significantly elevated overall by all analyses, and significantly so in particular race/sex subgroups.

Recent laboratory studies and clinical observations suggest that a robust collateral network must exist to explain preservation of spinal cord perfusion when segmental vessels are interrupted. An anatomical study was undertaken. METHODS Twelve juvenile Yorkshire pigs underwent aortic cannulation and infusion of a low-viscosity acrylic resin at physiological pressures. After curing of the resin and digestion of all organic tissue, the anatomy of the blood supply to the spinal cord was studied grossly and using light and electron microscopy. RESULTS All vascular structures ≥ 8μm in diameter were preserved. Thoracic and lumbar segmental arteries (SAs) give rise not only to the anterior spinal artery (ASA), but to an extensive paraspinous network feeding the erector spinae, iliopsoas, and associated muscles. The ASA, mean diameter 134±20 μm, is connected at multiple points to repetitive circular epidural arteries with mean diameters of 150±26 μm. The capacity of the paraspinous muscular network is 25-fold the capacity of the circular epidural arterial network and ASA combined. Extensive arterial collateralization is apparent between the intraspinal and paraspinous networks, and within each network. Only 75% of all SAs provide direct ASA-supplying branches.

METHODS: This cross-sectional sample included 33 adults (16 women) with classic galactosemia, mean age 32.0 ± 11.8 years.

It is classified as a probable human carcinogen, and developmental toxicity has been observed in rodents. Objectives: We examined the associations between prenatal exposure to acrylamide and birth outcomes in a prospective European mother–child study. Methods: Hemoglobin (Hb) adducts of acrylamide and its metabolite glycidamide were measured in cord blood (reflecting cumulated exposure in the last months of pregnancy) from 1,101 singleton pregnant women recruited in Denmark, England, Greece, Norway, and Spain during 2006–2010. Maternal diet was estimated through food-frequency questionnaires. Results: Both acrylamide and glycidamide Hb adducts were associated with a statistically significant reduction in birth weight and head circumference. The estimated difference in birth weight for infants in the highest versus lowest quartile of acrylamide Hb adduct levels after adjusting for gestational age and country was –132 g (95% CI: –207, –56); the corresponding difference for head circumference was –0.33 cm (95% CI: –0.61, –0.06). Findings were similar in infants of nonsmokers, were consistent across countries, and remained after adjustment for factors associated with reduced birth weight. Maternal consumption of foods rich in acrylamide, such as fried potatoes, was associated with cord blood acrylamide adduct levels and with reduced birth weight. Conclusions: Dietary exposure to acrylamide was associated with reduced birth weight and head circumference. Consumption of specific foods during pregnancy was associated with higher acrylamide exposure in utero. If confirmed, these findings suggest that dietary intake of acrylamide should be reduced among pregnant women.", "title": "Birth Weight, Head Circumference, and Prenatal Exposure to Acrylamide from Maternal Diet: The European Prospective Mother–Child Study (NewGeneris)" }, { "docid": "MED-872", "text": "Dental amalgam is 50% metallic mercury (Hg) by weight and Hg vapour continuously evolves from in-place dental amalgam, causing increased Hg content with increasing amalgam load in urine, faeces, exhaled breath, saliva, blood, and various organs and tissues including the kidney, pituitary gland, liver, and brain. The Hg content also increases with maternal amalgam load in amniotic fluid, placenta, cord blood, meconium, various foetal tissues including liver, kidney and brain, in colostrum and breast milk. Based on 2001 to 2004 population statistics, 181.1 million Americans carry a grand total of 1.46 billion restored teeth. Children as young as 26 months were recorded as having restored teeth. Past dental practice and recently available data indicate that the majority of these restorations are composed of dental amalgam. Employing recent US population-based statistics on body weight and the frequency of dentally restored tooth surfaces, and recent research on the incremental increase in urinary Hg concentration per amalgam-filled tooth surface, estimates of Hg exposure from amalgam fillings were determined for 5 age groups of the US population. Three specific exposure scenarios were considered, each scenario incrementally reducing the number of tooth surfaces assumed to be restored with amalgam. Based on the least conservative of the scenarios evaluated, it was estimated that some 67.2 million Americans would exceed the Hg dose associated with the reference exposure level (REL) of 0.3 μg/m(3) established by the US Environmental Protection Agency; and 122.3 million Americans would exceed the dose associated with the REL of 0.03 μg/m(3) established by the California Environmental Protection Agency. Exposure estimates are consistent with previous estimates presented by Health Canada in 1995, and amount to 0.2 to 0.4 μg/day per amalgam-filled tooth surface, or 0.5 to 1 μg/day/amalgam-filled tooth, depending on age and other factors.

Cosmetic-grade material may be extracted using hexane, ethanol, or vegetable oil and contain the full range of phytocompounds that are found in the Capsicum annuum or Capsicum frutescens plant (aka red chiles), including Capsaicin. Aflatoxin and N-nitroso compounds (N-nitrosodimethylamine and N-nitrosopyrrolidine) have been detected as contaminants. The ultraviolet (UV) absorption spectrum for Capsicum Annuum Fruit Extract indicates a small peak at approximately 275 nm, and a gradual increase in absorbance, beginning at approximately 400 nm. Capsicum and paprika are generally recognized as safe by the U.S. Food and Drug Administration for use in food. Hexane, chloroform, and ethyl acetate extracts of Capsicum Frutescens Fruit at 200 mg/kg resulted in death of all mice. In a short-term inhalation toxicity study using rats, no difference was found between vehicle control and a 7% Capsicum Oleoresin solution. In a 4-week feeding study, red chilli (Capsicum annuum) in the diet at concentrations up to 10% was relatively nontoxic in groups of male mice. In an 8-week feeding study using rats, intestinal exfoliation, cytoplasmic fatty vacuolation and centrilobular necrosis of hepatocytes, and aggregation of lymphocytes in the portal areas were seen at 10% Capsicum Frutescens Fruit, but not 2%. Rats fed 0.5 g/kg day-1 crude Capsicum Fruit Extract for 60 days exhibited no significant gross pathology at necropsy, but slight hyperemia of the liver and reddening of the gastric mucosa were observed. Weanling rats fed basal diets supplemented with whole red pepper at concentrations up to 5.0% for up to 8 weeks had no pathology of the large intestines, livers, and kidneys, but destruction of the taste buds and keratinization and erosion of the gastrointestinal (GI) tract were noted in groups fed 0.5% to 5.0% red pepper. The results of 9-and 12-month extension of this study showed normal large intestines and kidneys. In rabbits fed Capsicum Annuum Powder at 5 mg/kg day-1 in the diet daily for 12 months damage to the liver and spleen was noted. A rabbit skin irritation test of Capsicum Annuum Fruit Extract at concentrations ranging from 0.1% to 1.0% produced no irritation, but Capsicum Frutescens Fruit Extract induced concentration-dependent (at 25 to 500 microg/ml) cytotoxicity in a human buccal mucosa fibroblast cell line. An ethanol extract of red chili was mutagenic in Salmonella typhimurium TA98, but not in TA100, or in Escherichia coli. Other genotoxicity assays gave a similar pattern of mixed results. Adenocarcinoma of the abdomen was observed in 7/20 mice fed 100 mg red chilies per day for 12 months; no tumors were seen in control animals. Neoplastic changes in the liver and intestinal tumors were observed in rats fed red chili powder at 80 mg/kg day-1 for 30 days, intestinal and colon tumors were seen in rats fed red chili powder and 1,2-dimethyl hydrazine, but no tumors were observed in controls. In another study in rats, however, red chile pepper in the diet at the same dose decreased the number of tumors seen with 1,2-dimethylhydrazine. Other feeding studies evaluated the effect of red chili peppers on the incidence of stomach tumors produced by N-methyl-N'-nitro-N-nitrosoguanidine, finding that red pepper had a promoting effect. Capsicum Frutescens Fruit Extract promoted the carcinogenic effect of methyl(acetoxymethyl)nitrosamine (carcinogen) or benzene hexachloride (hepatocarcinogen) in inbred male and female Balb/c mice dosed orally (tongue application). Clinical findings include symptoms of cough, sneezing, and runny nose in chili factory workers. Human respiratory responses to Capsicum Oleoresin spray include burning of the throat, wheezing, dry cough, shortness of breath, gagging, gasping, inability to breathe or speak, and, rarely, cyanosis, apnea, and respiratory arrest. A trade name mixture containing 1% to 5% Capsicum Frutescens Fruit Extract induced very slight erythema in 1 of 10 volunteers patch tested for 48 h. Capsicum Frutescens Fruit Extract at 0.025% in a repeated-insult patch test using 103 subjects resulted in no clinically meaningful irritation or allergic contact dermatitis. One epidemiological study indicated that chili pepper consumption may be a strong risk factor for gastric cancer in populations with high intakes of chili pepper; however, other studies did not find this association. Capsaicin functions as an external analgesic, a fragrance ingredient, and as a skin-conditioning agent--miscellaneous in cosmetic products, but is not in current use. Capsaicin is not generally recognized as safe and effective by the U.S. Food and Drug Administration for fever blister and cold sore treatment, but is considered to be safe and effective as an external analgesic counterirritant. Ingested Capsaicin is rapidly absorbed from the stomach and small intestine in animal studies. Subcutaneous injection of Capsaicin in rats resulted in a rise in the blood concentration, reaching a maximum at 5 h; the highest tissue concentrations were in the kidney and lowest in the liver. In vitro percutaneous absorption of Capsaicin has been demonstrated in human, rat, mouse, rabbit, and pig skin. Enhancement of the skin permeation of naproxen (nonsteroidal anti-inflammatory agent) in the presence of Capsaicin has also been demonstrated. Pharmacological and physiological studies demonstrated that Capsaicin, which contains a vanillyl moiety, produces its sensory effects by activating a Ca2 +-permeable ion channel on sensory neurons. Capsaicin is a known activator of vanilloid receptor 1. Capsaicin-induced stimulation of prostaglandin biosynthesis has been shown using bull seminal vesicles and rheumatoid arthritis synoviocytes. Capsaicin inhibits protein synthesis in Vero kidney cells and human neuroblastoma SHSY-5Y cells in vitro, and inhibits growth of E. coli, Pseudomonas solanacearum, and Bacillus subtilis bacterial cultures, but not Saccharomyces cerevisiae. Oral LD50 values as low as 161.2 mg/kg (rats) and 118.8 mg/kg (mice) have been reported for Capsaicin in acute oral toxicity studies, with hemorrhage of the gastric fundus observed in some of the animals that died. Intravenous, intraperitoneal, and subcutaneous LD50 values were lower. In subchronic oral toxicity studies using mice, Capsaicin produced statistically significant differences in the growth rate and liver/body weight increases. Capsaicin is an ocular irritant in mice, rats, and rabbits. Dose-related edema was observed in animals receiving Capsaicin injections into the hindpaw (rats) or application to the ear (mice). In guinea pigs, dinitrochlorobenzene contact dermatitis was enhanced in the presence of Capsaicin, injected subcutaneously, whereas dermal application inhibited sensitization in mice. Immune system effects have been observed in neonatal rats injected subcutaneously with Capsaicin. Capsaicin produced mixed results in S. typhimurium micronucleus and sister-chromatid exchange genotoxicity assays. Positive results for Capsaicin were reported in DNA damage assays. Carcinogenic, cocarcinogenic, anticarcinogenic, antitumorigenic, tumor promotion, and anti-tumor promotion effects of Capsaicin have been reported in animal studies. Except for a significant reduction in crown-rump length in day 18 rats injected subcutaneously with Capsaicin (50 mg/kg) on gestation days 14, 16, 18, or 20, no reproductive or developmental toxicity was noted. In pregnant mice dosed subcutaneously with Capsaicin, depletion of substance P in the spinal cord and peripheral nerves of pregnant females and fetuses was noted. In clinical tests, nerve degeneration of intracutaneous nerve fibers and a decrease in pain sensation induced by heat and mechanical stimuli were evident in subjects injected intradermally with Capsaicin. An increase in mean inspiratory flow was reported for eight normal subjects who inhaled nebulized 10(-7) M Capsaicin. The results of provocative and predictive tests involving human subjects indicated that Capsaicin is a skin irritant. Overall, studies suggested that these ingredients can be irritating at low concentrations. Although the genotoxicity, carcinogenicity, and tumor promotion potential of Capsaicin have been demonstrated, so have opposite effects. Skin irritation and other tumor-promoting effects of Capsaicin appear to be mediated through interaction with the same vanilloid receptor. Given this mechanism of action and the observation that many tumor promoters are irritating to the skin, the Panel considered it likely that a potent tumor promoter may also be a moderate to severe skin irritant. Thus, a limitation on Capsaicin content that would significantly reduce its skin irritation potential is expected to, in effect, lessen any concerns relating to tumor promotion potential. Because Capsaicin enhanced the penetration of an anti-inflammatory agent through human skin, the Panel recommends that care should be exercised in using ingredients that contain Capsaicin in cosmetic products. The Panel advised industry that the total polychlorinated biphenyl (PCB)/pesticide contamination should be limited to not more than 40 ppm, with not more than 10 ppm for any specific residue, and agreed on the following limitations for other impurities: arsenic (3 mg/kg max), heavy metals (0.002% max), and lead (5 mg/kg max). Industry was also advised that aflatoxin should not be present in these ingredients (the Panel adopted < or =15 ppb as corresponding to \"negative\" aflatoxin content), and that ingredients derived from Capsicum annuum and Capsicum Frutescens Plant species should not be used in products where N-nitroso compounds may be formed.

Because naive T cells produce only IL-2 in short term culture, IFN-gamma production by this approach is a measure of a memory immune response. Stimulation of human PBLs or purified T lymphocytes with stimulator cells from inbred swine revealed a high frequency of IFN-gamma producers with 5-fold fewer IL-2 producers. In contrast, lymphocytes obtained from neonatal umbilical cord blood contained swine-specific IL-2 producers but few IFN-gamma producers, which is what one would expect to find with a naive phenotype. Moreover, PBLs from adults with a history of abstention from pork consumption responded to swine cells with a significantly lower frequency of IFN-gamma producers than PBLs from adults with unrestricted diets did, suggesting that pork consumption may result in priming of swine-specific T cell immunity.

OBJECTIVES: To evaluate whether occlusion of lumbar and middle sacral arteries or serum cholesterol levels are associated with lower back pain and/or with disc degeneration. SUMMARY OF BACKGROUND DATA: Atherosclerosis in the wall of the abdominal aorta usually develops at the ostia of branching arteries and the bifurcation, and may obliterate orifices of lumbar and middle sacral arteries. Obstruction of these arteries causes ischemia in the lumbar spine and may result in back symptoms and disc degeneration. METHODS: MR aortography and cholesterol blood tests were performed on 51 patients with long-term lower back pain without specific findings (i.e., spinal or nerve root compression) in regular lumbar MR images. The patients ranged from 35 to 70 years of age (mean age, 56 years). Serum cholesterol and low-density lipoprotein (LDL) cholesterol levels were measured. To assess symptoms and disability NASS low back Outcome Instrument was used. RESULTS: Twenty-nine (78%) of 37 men and 11 (77%) of 14 women showed occluded lumbar and/or middle sacral arteries. The prevalence of occluded arteries was 2.5 times more than in subjects of corresponding age group in a Finnish necropsy material. Twenty-three (62%) men and seven (50%) women had significant disc degeneration. Disc degeneration was associated with occluded lumbar/middle sacral arteries (P = 0.035). Patients with occluded arteries or significant disc degeneration did not complain more severe symptoms than those without, whereas patients with above normal serum LDL cholesterol scored higher in neurogenic symptoms (P = 0.031) and complained more often severe pain (P = 0.049) than those with normal LDL cholesterol. CONCLUSIONS: The study indicates that lumbar and middle sacral arteries are often occluded in patients with nonspecific long-term lower back pain.

We aimed to quantify the potential combined impact of four health behaviours on mortality in men and women living in the general community. Methods and Findings We examined the prospective relationship between lifestyle and mortality in a prospective population study of 20,244 men and women aged 45–79 y with no known cardiovascular disease or cancer at baseline survey in 1993–1997, living in the general community in the United Kingdom, and followed up to 2006. Participants scored one point for each health behaviour: current non-smoking, not physically inactive, moderate alcohol intake (1–14 units a week) and plasma vitamin C >50 mmol/l indicating fruit and vegetable intake of at least five servings a day, for a total score ranging from zero to four. After an average 11 y follow-up, the age-, sex-, body mass–, and social class–adjusted relative risks (95% confidence intervals) for all-cause mortality(1,987 deaths) for men and women who had three, two, one, and zero compared to four health behaviours were respectively, 1.39 (1.21–1.60), 1.95 (1.70–-2.25), 2.52 (2.13–3.00), and 4.04 (2.95–5.54) p < 0.001 trend. The relationships were consistent in subgroups stratified by sex, age, body mass index, and social class, and after excluding deaths within 2 y. The trends were strongest for cardiovascular causes. The mortality risk for those with four compared to zero health behaviours was equivalent to being 14 y younger in chronological age. Conclusions Four health behaviours combined predict a 4-fold difference in total mortality in men and women, with an estimated impact equivalent to 14 y in chronological age. Editors' Summary Background. Every day, or so it seems, new research shows that some aspect of lifestyle—physical activity, diet, alcohol consumption, and so on—affects health and longevity. For the person in the street, all this information is confusing. What is a healthy diet, for example? Although there are some common themes such as the benefit of eating plenty of fruit and vegetables, the details often differ between studies. And exactly how much physical activity is needed to improve health? Is a gentle daily walk sufficient or simply a stepping stone to doing enough exercise to make a real difference? The situation with alcohol consumption is equally confusing. Small amounts of alcohol apparently improve health but large amounts are harmful. As a result, it can be hard for public-health officials to find effective ways to encourage the behavioral changes that the scientific evidence suggests might influence the health of populations. Why Was This Study Done? There is another factor that is hindering official attempts to provide healthy lifestyle advice to the public. Although there is overwhelming evidence that individual behavioral factors influence health, there is very little information about their combined impact. If the combination of several small differences in lifestyle could be shown to have a marked effect on the health of populations, it might be easier to persuade people to make behavioral changes to improve their health, particularly if those changes were simple and relatively easy to achieve. In this study, which forms part of the European Prospective Investigation into Cancer and Nutrition (EPIC), the researchers have examined the relationship between lifestyle and the risk of dying using a health behavior score based on four simply defined behaviors—smoking, physical activity, alcohol drinking, and fruit and vegetable intake. What Did the Researchers Do and Find? Between 1993 and 1997, about 20,000 men and women aged 45–79 living in Norfolk UK, none of whom had cancer or cardiovascular disease (heart or circulation problems), completed a health and lifestyle questionnaire, had a health examination, and had their blood vitamin C level measured as part of the EPIC-Norfolk study. A health behavior score of between 0 and 4 was calculated for each participant by giving one point for each of the following healthy behaviors: current non-smoking, not physically inactive (physical inactivity was defined as having a sedentary job and doing no recreational exercise), moderate alcohol intake (1–14 units a week; a unit of alcohol is half a pint of beer, a glass of wine, or a shot of spirit), and a blood vitamin C level consistent with a fruit and vegetable intake of at least five servings a day. Deaths among the participants were then recorded until 2006. After allowing for other factors that might have affected their likelihood of dying (for example, age), people with a health behavior score of 0 were four times as likely to have died (in particular, from cardiovascular disease) than those with a score of 4. People with a score of 2 were twice as likely to have died. What Do These Findings Mean? These findings indicate that the combination of four simply defined health behaviors predicts a 4-fold difference in the risk of dying over an average period of 11 years for middle-aged and older people. They also show that the risk of death (particularly from cardiovascular disease) decreases as the number of positive health behaviors increase. Finally, they can be used to calculate that a person with a health score of 0 has the same risk of dying as a person with a health score of 4 who is 14 years older. These findings need to be confirmed in other populations and extended to an analysis of how these combined health behaviors affect the quality of life as well as the risk of death. Nevertheless, they strongly suggest that modest and achievable lifestyle changes could have a marked effect on the health of populations. Armed with this information, public-health officials should now be in a better position to encourage behavior changes likely to improve the health of middle-aged and older people.

The majority of health professionals seem to be promoting the theoretical concepts of lifestyle modification but experience difficulty in providing practical advice to patients. Of the health professionals evaluated, doctors appeared to have the best knowledge of lifestyle modification. Lack of time, lack of patient adherence and language barriers were given as the main barriers to providing lifestyle counselling. CONCLUSIONS: The undergraduate curricula of medical and nursing students should include sufficient training on lifestyle modification, particularly practical advice on diet, physical activity and smoking cessation.

We examined if adherence to ideal levels of the seven AHA cardiovascular health metrics was associated with incident cancers in the Atherosclerosis Risk In Communities (ARIC) study over 17-19 years of follow-up. Methods and Results After exclusions for missing data and prevalent cancer, 13,253 ARIC participants were included for analysis. Baseline measurements were used to classify participants according to seven AHA cardiovascular health metrics. Combined cancer incidence (excluding non-melanoma skin cancers) from 1987-2006 was captured using cancer registries and hospital surveillance; 2880 incident cancer cases occurred over follow-up. Cox regression was used to calculate hazard ratios for incident cancer. There was a significant (p-trend< .0001), graded, inverse association between the number of ideal cardiovascular health metrics at baseline and cancer incidence. Participants meeting goals for 6-7 ideal health metrics (2.7% of the population) had 51% lower risk of incident cancer than those meeting goals for 0 ideal health metrics. When smoking was removed from the sum of ideal health metrics, the association was attenuated with participants meeting goals for 5-6 health metrics having 25% lower cancer risk than those meeting goals for 0 ideal health metrics (p-trend = .03).

The objective of this study was to determine whether detection of childhood celiac disease by mass screening improves long-term health status and health-related quality of life. METHODS: We conducted a prospective 10-year follow-up study of 32 children who were aged 2 to 4 years, had celiac disease identified by mass screening, and had a gluten-free diet (19) or a normal gluten-containing diet (13). The follow-up included assessments of general health status, celiac disease-associated symptoms, celiac disease-associated serum antibodies, and health-related quality of life. RESULTS: Ten years after mass screening, 81% of the children were adhering to a gluten-free diet. The health status improved in 66% of the treated children: in 41% by early treatment and in 25% by prevention of the gluten-dependent symptoms that they developed after diagnosis. For 19% of the children, treatment after screening would not have improved their health status, because they had no symptoms at screening and have remained symptom-free while consuming gluten. The health-related quality of life of the children with symptoms improved significantly after 1 year of gluten-free diet. Ten years after screening, the health-related quality of life of the children with celiac disease was similar to that of the reference population. CONCLUSION: Identification by mass screening led 10 years later to health improvement in 66% of children without deterioration of generic health-related quality of life. There is a good compliance after mass screening. In a research setting, delaying treatment for children without symptoms seems to be an option after a positive screening test.

Ideal cardiovascular health, a concept well supported in the literature, is defined by the presence of both ideal health behaviors (nonsmoking, body mass index <25 kg/m(2), physical activity at goal levels, and pursuit of a diet consistent with current guideline recommendations) and ideal health factors (untreated total cholesterol <200 mg/dL, untreated blood pressure <120/<80 mm Hg, and fasting blood glucose <100 mg/dL).

REPORTING PERIOD: 1995-1996. DESCRIPTION OF SYSTEMS: This report uses data from CDC's National Center for Health Statistics (NCHS) to report on leading causes of death in 1996 (from the National Vital Statistics System), major causes of hospitalization (1996 National Hospital Discharge Survey [NHDSI), and major chronic conditions (1995 National Health Interview Survey [NHIS]). The National Vital Statistics System compiles information regarding all death certificates filed in the United States. NHDS is an annual probability sample of discharges from nonfederal, short-stay hospitals. NHIS is an ongoing annual cross-sectional household survey of the U.S. civilian, noninstitutionalized population. In addition, health-care expenditures for older adults are examined by using information obtained from published reports from the U.S. Health Care Financing Administration (HCFA) and health-services literature. RESULTS: The leading causes of death among adults aged > or =65 years were heart disease (1,808 deaths/100,000 population), malignant neoplasms (1,131/100,000), and cerebrovascular disease (415/100,000). Several leading causes of mortality among older adults differed by race, with deaths caused by Alzheimer's disease more frequent among whites and deaths caused by diabetes, kidney diseases, septicemia, and hypertension more frequent among blacks. Rates of hospitalization and length of hospital stays increased with age. Hospitalizations for heart disease represented the highest proportion of all discharges among older adults (23%). Discharge rates for malignant neoplasms, stroke, and pneumonia were similar for adults aged > or =65 years and, as with heart disease, were higher for men than for women. However, the rate of hospitalization for fractures among women exceeded the rate among men. Arthritis was the most prevalent chronic condition among adults aged > or =65 years (48.9/100 adults), followed by hypertension (40.3/100) and heart disease (28.6/100). In 1995, adults aged > or =65 years comprised 13% of the population but accounted for 35% of total personal health care dollars spent ($310 billion), and real per capita personal health-care expenditure for this age group increased at an average annual rate of 5.8% during 1985-1995. Projections for future medical expenditures for older adults vary; however, all project substantial increases after the year 2000. Hip fracture, dementia, and urinary incontinence are discussed as examples of prevalent and costly health conditions among older adults that differ in potential for prevention. These conditions were selected because they result in substantial medical and social costs and they differ in potential for prevention. INTERPRETATION: The higher prevalence of serious and costly health conditions among adults aged > or =65 years highlights the importance of implementing preventive health measures in this population.

OBJECTIVES: To measure the burden of diseases, injuries, and leading risk factors in the United States from 1990 to 2010 and to compare these measurements with those of the 34 countries in the Organisation for Economic Co-operation and Development (OECD) countries. DESIGN: We used the systematic analysis of descriptive epidemiology of 291 diseases and injuries, 1160 sequelae of these diseases and injuries, and 67 risk factors or clusters of risk factors from 1990 to 2010 for 187 countries developed for the Global Burden of Disease 2010 Study to describe the health status of the United States and to compare US health outcomes with those of 34 OECD countries. Years of life lost due to premature mortality (YLLs) were computed by multiplying the number of deaths at each age by a reference life expectancy at that age. Years lived with disability (YLDs) were calculated by multiplying prevalence (based on systematic reviews) by the disability weight (based on population-based surveys) for each sequela; disability in this study refers to any short- or long-term loss of health. Disability-adjusted life-years (DALYs) were estimated as the sum of YLDs and YLLs. Deaths and DALYs related to risk factors were based on systematic reviews and meta-analyses of exposure data and relative risks for risk-outcome pairs. Healthy life expectancy (HALE) was used to summarize overall population health, accounting for both length of life and levels of ill health experienced at different ages. RESULTS: US life expectancy for both sexes combined increased from 75.2 years in 1990 to 78.2 years in 2010; during the same period, HALE increased from 65.8 years to 68.1 years. The diseases and injuries with the largest number of YLLs in 2010 were ischemic heart disease, lung cancer, stroke, chronic obstructive pulmonary disease, and road injury. Age-standardized YLL rates increased for Alzheimer disease, drug use disorders, chronic kidney disease, kidney cancer, and falls. The diseases with the largest number of YLDs in 2010 were low back pain, major depressive disorder, other musculoskeletal disorders, neck pain, and anxiety disorders. As the US population has aged, YLDs have comprised a larger share of DALYs than have YLLs. The leading risk factors related to DALYs were dietary risks, tobacco smoking, high body mass index, high blood pressure, high fasting plasma glucose, physical inactivity, and alcohol use. Among 34 OECD countries between 1990 and 2010, the US rank for the age-standardized death rate changed from 18th to 27th, for the age-standardized YLL rate from 23rd to 28th, for the age-standardized YLD rate from 5th to 6th, for life expectancy at birth from 20th to 27th, and for HALE from 14th to 26th. CONCLUSIONS AND RELEVANCE: From 1990 to 2010, the United States made substantial progress in improving health. Life expectancy at birth and HALE increased, all-cause death rates at all ages decreased, and age-specific rates of years lived with disability remained stable. However, morbidity and chronic disability now account for nearly half of the US health burden, and improvements in population health in the United States have not kept pace with advances in population health in other wealthy nations.", "title": "The state of US health, 1990-2010: burden of diseases, injuries, and risk factors." } ]

There are places around the world where people live longer and they are active past the age of 100 years, sharing common behavioral characteristics; these places (i.e., Sardinia in Italy, Okinawa in Japan, Loma Linda in California and Nicoya Peninsula in Costa Rica) have been named the “Blue Zones”. Recently it was reported that people in Ikaria Island, Greece, have also one of the highest life expectancies in the world, and joined the “Blue Zones”. The aim of this work work was to evaluate various demographic, lifestyle and psychological characteristics of very old (>80 years) people participated in Ikaria Study. Methods. During 2009, 1420 people (aged 30+) men and women from Ikaria Island, Greece, were voluntarily enrolled in the study. For this work, 89 males and 98 females over the age of 80 yrs were studied (13% of the sample). Socio-demographic, clinical, psychological and lifestyle characteristics were assessed using standard questionnaires and procedures. Results. A large proportion of the Ikaria Study's sample was over the age of 80; moreover, the percent of people over 90 were much higher than the European population average. The majority of the oldest old participants reported daily physical activities, healthy eating habits, avoidance of smoking, frequent socializing, mid-day naps and extremely low rates of depression. Conclusion. Modifiable risk factors, such as physical activity, diet, smoking cessation and mid-day naps, might depict the “secrets” of the long-livers; these findings suggest that the interaction of environmental, behavioral together with clinical characteristics may determine longevity.

Glycolytic metabolism is markedly accelerated in cancer cells, causing the accumulation of glucose (a reducing sugar) and methionine (an amino acid), which can non-enzymatically react and form carcinogenic substances. There is speculation that this reaction produces gaseous sulfur-containing compounds in tumour tissue. The aims of this study were to clarify the products in tumour and to investigate their effect on tumour proliferation. METHODS: Products formed in the reaction between glucose and methionine or its metabolites were analysed in vitro using gas chromatography. Flatus samples from patients with colon cancer and exhaled air samples from patients with lung cancer were analysed using near-edge x-ray fine adsorption structure spectroscopy and compared with those from healthy individuals. The tumour proliferation rates of mice into which HT29 human colon cancer cells had been implanted were compared with those of mice in which the cancer cells were surrounded by sodium hyaluronate gel to prevent diffusion of gaseous material into the healthy cells. RESULTS: Gaseous sulfur-containing compounds such as methanethiol and hydrogen sulfide were produced when glucose was allowed to react with methionine or its metabolites homocysteine or cysteine. Near-edge x-ray fine adsorption structure spectroscopy showed that the concentrations of sulfur-containing compounds in the samples of flatus from patients with colon cancer and in the samples of exhaled air from patients with lung cancer were significantly higher than in those from healthy individuals. Animal experiments showed that preventing the diffusion of sulfur-containing compounds had a pronounced antitumour effect. CONCLUSIONS: Gaseous sulfur-containing compounds are the main products in tumours and preventing the diffusion of these compounds reduces the tumour proliferation rate, which suggests the possibility of a new approach to cancer treatment.", "title": "Generation of gaseous sulfur-containing compounds in tumour tissue and suppression of gas diffusion as an antitumour treatment." }, { "docid": "MED-3274", "text": "Objective To determine whether dogs can be trained to identify people with bladder cancer on the basis of urine odour more successfully than would be expected by chance alone. Design Experimental, “proof of principle” study in which six dogs were trained to discriminate between urine from patients with bladder cancer and urine from diseased and healthy controls and then evaluated in tests requiring the selection of one bladder cancer urine sample from six controls. Participants 36 male and female patients (age range 48-90 years) presenting with new or recurrent transitional cell carcinoma of the bladder (27 samples used for training; 9 used for formal testing); 108 male and female controls (diseased and healthy, age range 18-85 years—54 samples used in training; 54 used for testing).

Results Taken as a group, the dogs correctly selected urine from patients with bladder cancer on 22 out of 54 occasions. This gave a mean success rate of 41% (95% confidence intervals 23% to 58% under assumptions of normality, 26% to 52% using bootstrap methods), compared with 14% expected by chance alone. Multivariate analysis suggested that the dogs' capacity to recognise a characteristic bladder cancer odour was independent of other chemical aspects of the urine detectable by urinalysis. Conclusions Dogs can be trained to distinguish patients with bladder cancer on the basis of urine odour more successfully than would be expected by chance alone.

AREAS COVERED: In this review we explore the discovery of methionine auxotrophy followed by in vitro, in vivo and patient data on targeting cancer with methionine depletion. We end with a small discussion on bioengineering, pegylation and red blood cell encapsulation as mechanisms for decreasing immunogenicity of methionine-depleting drugs. We hope to provide a platform for future pharmacology, toxicology and cytotoxicity studies with methionine depletion therapy and drugs. EXPERT OPINION: Although methionine auxotrophy seems as a viable target, extensive research addressing normal versus cancer cell toxicity needs to be conducted. Further research also needs to be conducted into the molecular mechanism associated with methionine depletion therapy. Finally, novel methods need to be developed to decrease the immunogenicity of methionine-depleting drugs, a current issue with protein therapeutics.", "title": "Targeting methionine auxotrophy in cancer: discovery & exploration." }, { "docid": "MED-4327", "text": "Hyperphosphatemia and hyperparathyroidism, frequently observed in patients with endstage renal disease, are associated with renal osteodystrophy, organ calcification, cardiovascular disease and sudden death. Restriction of dietary protein and phosphorus is beneficial in slowing the progression of renal failure. Dietary phosphorus restriction must be prescribed at all stages of renal failure in adults. It may be achieved by decreasing protein intake and avoiding foods rich in phosphorus. An average of 60-80% of the phosphorus intake is absorbed in the gut in dialysis patients. If phosphate binders are employed, the phosphorus absorbed from the diet may be reduced to 40%. Conventional hemodialysis with a high-flux, high-efficiency dialyzer removes approximately 30 mmol (900 mg) phosphorus during each dialysis performed three times weekly. Therefore, 750 mg of phosphorus intake should be the critical value above which a positive balance of phosphorus may occur. This value corresponds to a protein diet of 45-50 g/day or 0.8 g/kg body weight/day for a 60 kg patient. Target levels should become 9.2-9.6 mg/dl for calcium, 2.5-5.5 mg/dl for phosphorus, <55 mg2/dl2 for the calcium-phosphorus product, and 100-200 pg/ml for intact parathyroid hormone.", "title": "Phosphate restriction in diet therapy." }, { "docid": "MED-2290", "text": "Background Differences in nutrient profiles between vegetarian and non vegetarian dietary patterns reflect nutritional differences that may contribute to the development of disease.

Participants completed a 204-item validated semi-quantitative food frequency questionnaire. Dietary patterns compared were: non vegetarian, semi vegetarian, pesco vegetarian, lacto-ovo vegetarian and strict vegetarian. ANCOVA was used to analyze differences in nutrient intakes by dietary patterns and were adjusted for age, and sex and race. BMI and other relevant demographic data were reported and compared by dietary pattern using chi-square tests and ANOVA. Results Many nutrient intakes varied significantly between dietary patterns. Non vegetarians had the lowest intakes of plant proteins, fiber, β-Carotene, and Mg than those following vegetarian dietary patterns and the highest intakes of saturated, trans, arachidonic, and docosahexaenoic fatty acids. The lower tails of some nutrient distributions in strict vegetarians suggested inadequate intakes by a portion of the subjects. Energy intake was similar among dietary patterns at close to 2000 kcal/d with the exception of semi vegetarians that had an intake of 1713 kcal/d. Mean BMI was highest in non-vegetarians (mean; standard deviation [SD]) (28.7; [6.4]) and lowest in strict vegetarians (24.0; [4.8]).

New therapeutic strategies must be identified, and the metabolic abnormalities of cancer cells offer such opportunities. Many human cancer cell lines and primary tumors have absolute requirements for methionine, an essential amino acid. In contrast, normal cells are relatively resistant to exogenous methionine restriction. The biochemical mechanism for methionine dependency has been studied extensively, but the fundamental mechanism remains unclear. A number of investigators have attempted to exploit the methionine dependence of tumors for therapeutic effects in vivo. To reduce in vivo methionine in plasma and tumours, dietary and pharmacological treatments have been used. Methionine-free diet or methionine-deprived total parenteral nutrition causes regression of a variety of animal tumours. Alternatively, methionine depletion was achieved by the use of methioninase. This enzyme specifically degrades methionine and inhibits tumour growth in preclinical models. Because of potential toxicity and quality of life problems, prolonged methionine restriction with diet or with methioninase is not suitable for clinical use. Methionine restriction may find greater application in association with various chemotherapeutic agents. Several preclinical studies have demonstrated synergy between methionine restriction and various cytotoxic chemotherapy drugs.

Because a pure vegetarian diet might not easily be embraced by many individuals, consuming preferentially plant-derived foods would be a more easily understood message. A provegetarian food pattern (FP) emphasizing preference for plant-derived foods might reduce all-cause mortality. OBJECTIVE: The objective was to identify the association between an a priori-defined provegetarian FP and all-cause mortality. DESIGN: We followed 7216 participants (57% women; mean age: 67 y) at high cardiovascular risk for a median of 4.8 y. A validated 137-item semiquantitative food-frequency questionnaire was administered at baseline and yearly thereafter. Fruit, vegetables, nuts, cereals, legumes, olive oil, and potatoes were positively weighted. Added animal fats, eggs, fish, dairy products, and meats or meat products were negatively weighted. Energy-adjusted quintiles were used to assign points to build the provegetarian FP (range: 12-60 points). Deaths were confirmed by review of medical records and the National Death Index. RESULTS: There were 323 deaths during the follow-up period (76 from cardiovascular causes, 130 from cancer, 117 for noncancer, noncardiovascular causes). Higher baseline conformity with the provegetarian FP was associated with lower mortality (multivariable-adjusted HR for ≥ 40 compared with <30 points: 0.59; 95% CI: 0.40, 0.88).

Oxidation of proteins has been proposed to be one of the basic mechanisms linking oxygen radicals with the basic aging process. If oxidative damage to proteins is involved in aging, long-lived animals (which age slowly) should show lower levels of markers of this kind of damage than short-lived ones. However, this possibility has not been investigated yet. In this study, steady-state levels of markers of different kinds of protein damage--oxidation (glutamic and aminoadipic semialdehydes), mixed glyco- and lipoxidation (carboxymethyl- and carboxyethyllysine), lipoxidation (malondialdehydelysine) and amino acid composition--were measured in the heart of eight mammalian species ranging in maximum life span (MLSP) from 3.5 to 46 years. Oxidation markers were directly correlated with MLSP across species. Mixed glyco- and lipoxidation markers did not correlate with MLSP. However, the lipoxidation marker malondialdehydelysine was inversely correlated with MLSP (r2=0.85; P<0.001). The amino acid compositional analysis revealed that methionine is the only amino acid strongly correlated MLSP and that such correlation is negative (r2=0.93; P<0.001). This trait may contribute to lower steady-state levels of oxidized methionine residues in cellular proteins.

A mailed questionnaire provided dietary and other exposure information at study baseline. Mortality for all subjects was ascertained by matching to state death tapes and the National Death Index. RESULTS: California Adventists have higher life expectancies at the age of 30 years than other white Californians by 7.28 years (95% confidence interval, 6.59-7.97 years) in men and by 4.42 years (95% confidence interval, 3.96-4.88 years) in women, giving them perhaps the highest life expectancy of any formally described population. Commonly observed combinations of diet, exercise, body mass index, past smoking habits, and hormone replacement therapy (in women) can account for differences of up to 10 years of life expectancy among Adventists.

The development of a novel screening method that is as economical and non-invasive as the faecal occult blood test (FOBT) for early detection of colorectal cancer (CRC) is needed. A study was undertaken using canine scent detection to determine whether odour material can become an effective tool in CRC screening. Design Exhaled breath and watery stool samples were obtained from patients with CRC and from healthy controls prior to colonoscopy. Each test group consisted of one sample from a patient with CRC and four control samples from volunteers without cancer. These five samples were randomly and separately placed into five boxes. A Labrador retriever specially trained in scent detection of cancer and a handler cooperated in the tests. The dog first smelled a standard breath sample from a patient with CRC, then smelled each sample station and sat down in front of the station in which a cancer scent was detected. Results 33 and 37 groups of breath and watery stool samples, respectively, were tested. Among patients with CRC and controls, the sensitivity of canine scent detection of breath samples compared with conventional diagnosis by colonoscopy was 0.91 and the specificity was 0.99. The sensitivity of canine scent detection of stool samples was 0.97 and the specificity was 0.99. The accuracy of canine scent detection was high even for early cancer. Canine scent detection was not confounded by current smoking, benign colorectal disease or inflammatory disease.

In order to determine whether methionine dependence occurs in fresh patient tumors as well as whether methionine dependence occurs in fresh patient tumors as well as in cell lines we took advantage of the technique of sponge-gel-supported histoculture to grow tumors directly from surgery. We then measured nuclear DNA content by image analysis to determine the cell cycle position in MET-HCY+ compared to MET+HCY- medium in 21 human patient tumors.

Therefore late cell cycle arrest was used as a marker of methionine dependence for histocultured patient tumors. We found that 5 human tumors of 21, including tumors of the colon, breast, ovary, prostate, and a melanoma, were methionine dependent based on cell cycle analysis.

We undertook this study to examine the association between lifelong vegetarian diet and bone mineral density and body composition in a group of postmenopausal women. METHODS: One hundred and five Mahayana Buddhist nuns and 105 omnivorous women (average age = 62, range = 50-85) were randomly sampled from monasteries in Ho Chi Minh City and invited to participate in the study. By religious rule, the nuns do not eat meat or seafood (i.e., vegans). Bone mineral density (BMD) at the lumbar spine (LS), femoral neck (FN), and whole body (WB) was measured by DXA (Hologic QDR 4500). Lean mass, fat mass, and percent fat mass were also obtained from the DXA whole body scan. Dietary calcium and protein intakes were estimated from a validated food frequency questionnaire. RESULTS: There was no significant difference between vegans and omnivores in LSBMD (0.74 +/- 0.14 vs. 0.77 +/- 0.14 g/cm(2); mean +/- SD; P = 0.18), FNBMD (0.62 +/- 0.11 vs. 0.63 +/- 0.11 g/cm(2); P = 0.35), WBBMD (0.88 +/- 0.11 vs. 0.90 +/- 0.12 g/cm(2); P = 0.31), lean mass (32 +/- 5 vs. 33 +/- 4 kg; P = 0.47), and fat mass (19 +/- 5 vs. 19 +/- 5 kg; P = 0.77) either before or after adjusting for age. The prevalence of osteoporosis (T scores < or = -2.5) at the femoral neck in vegans and omnivores was 17.1% and 14.3% (P = 0.57), respectively.

Chitin is an eukaryotic extracellular aminosugar biopolymer, massively produced by most fungal systems and by invertebrates, notably arthropods. Being an integral supportive component in fungal cell wall, insect cuticle, and nematode egg shell, chitin has been considered as a selective target for pesticide action. Throughout the elaborate processes of chitin formation and deposition, only the polymerization events associated with the cell membrane compartment are so far available for chemical interference. Currently, the actinomycetes-derived nucleoside peptide fungicides such as the polyoxins and the insecticidal benzoylaryl ureas have reached commercial pesticide status. The polyoxins and other structurally-related antibiotics like nikkomycins are strong competitive inhibitors of the polymerizing enzyme chitin synthase. The exact biochemical lesion inflicted by the benzoylaryl ureas is still elusive, but a post-polymerization event, such as translocation of chitin chains across the cell membrane, is suggested. Hydrolytic degradation of the chitin polymer is essential for hyphal growth, branching, and septum formation in fungal systems as well as for the normal molting of arthropods. Recently, insect chitinase activity was strongly and specifically suppressed by allosamidin, an actimomycetes-derived metabolite.

Furthermore, low-fat vegan diets, coupled with exercise training, can be expected to promote longevity by decreasing systemic levels of insulin and free IGF-I; the latter effect would be amplified by methionine restriction - though it is not clear whether IGF-I down-regulation is the sole basis for the impact of low-methionine diets on longevity in rodents.", "title": "The low-methionine content of vegan diets may make methionine restriction feasible as a life extension strategy." } ]

The iodine status and thyroid function of U.S. vegetarians and vegans have not been previously studied. Environmental perchlorate and thiocyanate (inhibitors of thyroid iodine uptake) exposures may adversely affect thyroid function. Objective: The objective of the study was to assess the iodine status and thyroid function of U.S. vegetarians (consume plant based products, eggs, milk; abstain from meat, poultry, fish, shellfish) and vegans (avoid all animal products) and whether these may be affected by environmental perchlorate and thiocyanate exposures. Design and Setting: This was a cross-sectional assessment of urinary iodine, perchlorate, and thiocyanate concentrations and serum thyroid function in Boston-area vegetarians and vegans. Subjects: One hundred forty-one subjects (78 vegetarians, 63 vegans) were recruited; one vegan was excluded. Results: Median urinary iodine concentration of vegans (78.5 μg/liter; range 6.8–964.7 μg/liter) was lower than vegetarians (147.0 μg/liter; range 9.3–778.6 μg/liter) (P < 0.01). Adjusted for cigarette smoking (confirmed by urinary cotinine levels) and thiocyanate-rich food consumption, median urinary thiocyanate concentration of vegans (630 μg/liter; range 108-3085 μg/liter) was higher than vegetarians (341 μg/liter; range 31–1963 μg/liter) (P < 0.01).

Therefore, we aimed to estimate the long-term effect of a vegan diet on serum B-12 concentrations in healthy omnivore adults, comparing the influence of natural products consumption and B-12 fortified food. MATERIAL AND METHODS: A five year prospective study was carried out comprising 20 omnivore healthy adult subjects, who moved to strict vegan diet for 5 years. Ten volunteers followed vegan diet based entirely on natural products, while the remaining ten subjects consumed food fortified in B-12. In all subjects serum vitamin B-12 concentration was determined before and 6, 12, 24 and 60 months after the implementation of the diet.

Soy protein, as well as many other vegan proteins, are higher in non-essential amino acids than most animal-derived food proteins, and as a result should preferentially favor glucagon production. Acting on hepatocytes, glucagon promotes (and insulin inhibits) cAMP-dependent mechanisms that down-regulate lipogenic enzymes and cholesterol synthesis, while up-regulating hepatic LDL receptors and production of the IGF-I antagonist IGFBP-1. The insulin-sensitizing properties of many vegan diets--high in fiber, low in saturated fat--should amplify these effects by down-regulating insulin secretion. Additionally, the relatively low essential amino acid content of some vegan diets may decrease hepatic IGF-I synthesis. Thus, diets featuring vegan proteins can be expected to lower elevated serum lipid levels, promote weight loss, and decrease circulating IGF-I activity. The latter effect should impede cancer induction (as is seen in animal studies with soy protein), lessen neutrophil-mediated inflammatory damage, and slow growth and maturation in children. In fact, vegans tend to have low serum lipids, lean physiques, shorter stature, later puberty, and decreased risk for certain prominent 'Western' cancers; a vegan diet has documented clinical efficacy in rheumatoid arthritis. Low-fat vegan diets may be especially protective in regard to cancers linked to insulin resistance--namely, breast and colon cancer--as well as prostate cancer; conversely, the high IGF-I activity associated with heavy ingestion of animal products may be largely responsible for the epidemic of 'Western' cancers in wealthy societies. Increased phytochemical intake is also likely to contribute to the reduction of cancer risk in vegans. Regression of coronary stenoses has been documented during low-fat vegan diets coupled with exercise training; such regimens also tend to markedly improve diabetic control and lower elevated blood pressure. Risk of many other degenerative disorders may be decreased in vegans, although reduced growth factor activity may be responsible for an increased risk of hemorrhagic stroke. By altering the glucagon/insulin balance, it is conceivable that supplemental intakes of key non-essential amino acids could enable omnivores to enjoy some of the health advantages of a vegan diet.

Since current PD prevalence in African-Americans is little different from that in whites, environmental factors are likely to be responsible for the low PD risk in black Africans. In aggregate, these findings suggest that vegan diets may be notably protective with respect to PD. However, they offer no insight into whether saturated fat, compounds associated with animal fat, animal protein, or the integrated impact of the components of animal products mediates the risk associated with animal fat consumption. Caloric restriction has recently been shown to protect the central dopaminergic neurons of mice from neurotoxins, at least in part by induction of heat-shock proteins; conceivably, the protection afforded by vegan diets reflects a similar mechanism. The possibility that vegan diets could be therapeutically beneficial in PD, by slowing the loss of surviving dopaminergic neurons, thus retarding progression of the syndrome, may merit examination.

IGF-I and prolactin, which are lymphocyte growth factors, may have the potential to suppress apoptosis in thymocytes and thus encourage autoimmunity; conversely, dietary fish oil rich in omega-3 fats appears to upregulate apoptosis in lymphocytes. Since whole-food vegan diets may downregulate systemic IGF-I activity, it is proposed that such a diet, in conjunction with fish oil supplementation and treatment with dopamine agonists capable of suppressing prolactin secretion, may have utility for treating and preventing autoimmune disorders. This prediction is consistent with the extreme rarity of autoimmune disorders among sub-Saharan black Africans as long as they followed their traditional quasi-vegan lifestyles, and with recent ecologic studies correlating risks for IDDM and for multiple sclerosis mortality with animal product and/or saturated fat consumption. Moreover, there is evidence that vegan or quasi-vegan diets are useful in the management of rheumatoid arthritis, multiple sclerosis, and possibly SLE. The dopamine agonist bromocryptine exerts anti-inflammatory effects in rodent models of autoimmunity, and there is preliminary evidence that this drug may be clinically useful in several human autoimmune diseases; better tolerated D2-specific agonists such as cabergoline may prove to be more practical for use in therapy. The moderate clinical utility of supplemental fish oil in rheumatoid arthritis and certain other autoimmune disorders is documented. It is not unlikely that extra-thymic anti-inflammatory effects contribute importantly to the clinical utility of vegan diets, bromocryptine, and fish oil in autoimmunity. The favorable impact of low latitude or high altitude on autoimmune risk may be mediated by superior vitamin D status, which is associated with decreased secretion of parathyroid hormone; there are theoretical grounds for suspecting that parathyroid hormone may inhibit apoptosis in thymocytes. Androgens appear to up-regulate thymocyte apoptosis, may be largely responsible for the relative protection from autoimmunity enjoyed by men, and merit further evaluation for the management of autoimmunity in women. It will probably prove more practical to prevent autoimmune disorders than to reverse them once established; a whole-food vegan diet, coupled with fish oil and vitamin D supplementation, may represent a practical strategy for achieving this prevention, while concurrently lowering risk for many other life-threatening 'Western' diseases.

Previous reports indicate that risk for pancreatic cancer is increased in adult-onset diabetics. Since streptozotocin diabetes inhibits carcinogen-mediated induction of pancreatic cancer in hamsters, the most reasonable interpretation of these findings is that insulin (or some other beta cell product) acts as a promoter for pancreatic carcinogenesis. This view is consistent with a report that human pancreatic adenocarcinomas express insulin receptors that can stimulate mitosis; an additional possibility is that high insulin levels indirectly promote pancreatic carcinogenesis by boosting effective IGF-I activity via hepatic actions. In international ecologic epidemiology, pancreatic cancer rates correlate tightly with dietary intake of animal products; this may reflect the fact that vegan diets are associated with low diurnal insulin secretion. There is also suggestive evidence that macrobiotic vegan diets, which are low in glycemic index, may increase mean survival time in pancreatic cancer. However, other types of diets associated with decreased postprandial insulin response, such as high-protein diets or 'Mediterranean' diets high in oleic acid, may also have the potential for pancreatic cancer prevention. The huge increases of age-adjusted pancreatic cancer mortality in Japan and among African-Americans during the last century imply that pancreatic cancer is substantially preventable; a low-insulin-response diet coupled with exercise training, weight control, and smoking avoidance, commendable for a great many other reasons, may slash pancreatic cancer mortality dramatically.

Herein we demonstrate that intestinal microbiota metabolism of dietary L-carnitine, a trimethylamine abundant in red meat, also produces TMAO and accelerates atherosclerosis. Omnivorous subjects are shown to produce significantly more TMAO than vegans/vegetarians following ingestion of L-carnitine through a microbiota-dependent mechanism. Specific bacterial taxa in human feces are shown to associate with both plasma TMAO and dietary status. Plasma L-carnitine levels in subjects undergoing cardiac evaluation (n = 2,595) predict increased risks for both prevalent cardiovascular disease (CVD) and incident major adverse cardiac events (MI, stroke or death), but only among subjects with concurrently high TMAO levels. Chronic dietary L-carnitine supplementation in mice significantly altered cecal microbial composition, markedly enhanced synthesis of TMA/TMAO, and increased atherosclerosis, but not following suppression of intestinal microbiota. Dietary supplementation of TMAO, or either carnitine or choline in mice with intact intestinal microbiota, significantly reduced reverse cholesterol transport in vivo.

Western nutrition is characterized by high calorie uptake, high glycemic load, high fat and meat intake, as well as increased consumption of insulin- and IGF-1-level elevating dairy proteins. Metabolic signals of Western diet are sensed by the nutrient-sensitive kinase, mammalian target of rapamycin complex 1 (mTORC1), which integrates signals of cellular energy, growth factors (insulin, IGF-1) and protein-derived signals, predominantly leucine, provided in high amounts by milk proteins and meat. mTORC1 activates SREBP, the master transcription factor of lipogenesis. Leucine stimulates mTORC1-SREBP signaling and leucine is directly converted by sebocytes into fatty acids and sterols for sebaceous lipid synthesis. Over-activated mTORC1 increases androgen hormone secretion and most likely amplifies androgen-driven mTORC1 signaling of sebaceous follicles. Testosterone directly activates mTORC1. Future research should investigate the effects of isotretinoin on sebocyte mTORC1 activity. It is conceivable that isotretinoin may downregulate mTORC1 in sebocytes by upregulation of nuclear levels of FoxO1. The role of Western diet in acne can only be fully appreciated when all stimulatory inputs for maximal mTORC1 activation, i.e., glucose, insulin, IGF-1 and leucine, are adequately considered. Epidemic acne has to be recognized as an mTORC1-driven disease of civilization like obesity, type 2 diabetes, cancer and neurodegenerative diseases. These new insights into Western diet-mediated mTORC1-hyperactivity provide a rational basis for dietary intervention in acne by attenuating mTORC1 signaling by reducing (1) total energy intake, (2) hyperglycemic carbohydrates, (3) insulinotropic dairy proteins and (4) leucine-rich meat and dairy proteins. The necessary dietary changes are opposed to the evolution of industrialized food and fast food distribution of Westernized countries. An attenuation of mTORC1 signaling is only possible by increasing the consumption of vegetables and fruit, the major components of vegan or Paleolithic diets. The dermatologist bears a tremendous responsibility for his young acne patients who should be advised to modify their dietary habits in order to reduce activating stimuli of mTORC1, not only to improve acne but to prevent the harmful and expensive march to other mTORC1-related chronic diseases later in life.", "title": "Dietary intervention in acne" }, { "docid": "MED-4683", "text": "Background/Objectives Vegans and to a lesser extent vegetarians have low average circulating concentrations of vitamin B12; however, the relation between factors such as age or time on these diets and vitamin B12 concentrations is not clear.

Some published results have shown an association between circulating IGF1 and breast-cancer risk, but it has been unclear whether this relationship is consistent or whether it is modified by IGF binding protein 3 (IGFBP3), menopausal status, oestrogen receptor status or other factors. The relationship of IGF1 (and IGFBP3) with breast-cancer risk factors is also unclear. The Endogenous Hormones and Breast Cancer Collaborative Group was established to analyse pooled individual data from prospective studies to increase the precision of the estimated associations of endogenous hormones with breast-cancer risk. Methods Individual data on prediagnostic IGF1 and IGFBP3 concentrations were obtained from 17 prospective studies in 12 countries. The associations of IGF1 with risk factors for breast cancer in controls were examined by calculating geometric mean concentrations in categories of these factors. The odds ratios (ORs) with 95% CIs of breast cancer associated with increasing IGF1 concentrations were estimated by conditional logistic regression in 4790 cases and 9428 matched controls, with stratification by study, age at baseline, and date of baseline. All statistical tests were two-sided, and a p value of less than 0·05 was considered significant. Findings IGF1 concentrations, adjusted for age, were positively associated with height and age at first pregnancy, inversely associated with age at menarche and years since menopause, and were higher in moderately overweight women and moderate alcohol consumers than in other women. The OR for breast cancer for women in the highest versus the lowest fifth of IGF1 concentration was 1·28 (95% CI 1·14–1·44; p<0·0001). This association was not altered by adjusting for IGFBP3, and did not vary significantly by menopausal status at blood collection. The ORs for a difference in IGF1 concentration between the highest and lowest fifth were 1·38 (95% CI 1·14–1·68) for oestrogen-receptor-positive tumours and 0·80 (0·57–1·13) for oestrogen-receptor-negative tumours (p for heterogeneity=0·007). Interpretation Circulating IGF1 is positively associated with breast-cancer risk. The association is not substantially modified by IGFBP3, and does not differ markedly by menopausal status, but seems to be confined to oestrogen-receptor-positive tumours.

METHODS: Analysis of major tobacco industries' internal secret documents on cigarette radioactivity made available online by the Master Settlement Agreement in 1998. RESULTS: The documents show that the industry was well aware of the presence of a radioactive substance in tobacco as early as 1959. Furthermore, the industry was not only cognizant of the potential \"cancerous growth\" in the lungs of regular smokers but also did quantitative radiobiological calculations to estimate the long-term (25 years) lung radiation absorption dose (rad) of ionizing alpha particles emitted from the cigarette smoke. Our own calculations of lung rad of alpha particles match closely the rad estimated by the industry. According to the Environmental Protection Agency, the industry's and our estimate of long-term lung rad of alpha particles causes 120-138 lung cancer deaths per year per 1,000 regular smokers. Acid wash was discovered in 1980 to be highly effectively in removing (210)Po from the tobacco leaves; however, the industry avoided its use for concerns that acid media would ionize nicotine converting it into a poorly absorbable form into the brain of smokers thus depriving them of the much sought after instant \"nicotine kick\" sensation.

Previously recognized associations with environmental and parental factors were examined, focusing particularly on the hypothesized hormonal link. Multivariate logistic regression was used to identify independent associations. RESULTS: Of 7928 boys born to mothers taking part in the Avon Longitudinal Study of Pregnancy and Childhood, 51 hypospadias cases were identified. There were no significant differences in the proportion of hypospadias cases among mothers who smoked, consumed alcohol or for any aspect of their previous reproductive history (including the number of previous pregnancies, number of miscarriages, use of the contraceptive pill, time to conception and age at menarche). Significant differences were detected for some aspects of the maternal diet, i.e. vegetarianism and iron supplementation in the first half of pregnancy. Mothers who were vegetarian in pregnancy had an adjusted odds ratio (OR) of 4.99 (95% confidence interval, CI, 2.10-11.88) of giving birth to a boy with hypospadias, compared with omnivores who did not supplement their diet with iron. Omnivores who supplemented their diet with iron had an adjusted OR of 2.07 (95% CI, 1.00-4.32). The only other statistically significant association for hypospadias was with influenza in the first 3 months of pregnancy (adjusted OR 3.19, 95% CI 1.50-6.78).

Methods Nationally representative weighted percentages and means of daily energy intake by eating location were analyzed for trends from 1977 to 2006. Comparisons by food source were examined from 1994 to 2006. Analyses were repeated for 3 age groups: 2–6, 7–12, and 13–18 year olds. Difference testing was conducted using a t test. Results Increased energy intake (+179 kcal/d) by children from 1977–2006 was associated with a major increase in calories eaten away-from-home (+255 kcal/d). The percentage of kcal/d eaten away-from-home increased from 23.4% to 33.9% from 1977–2006. No further increase was observed from 1994–2006, but the sources of calories shifted.

SETTING: We measured the phosphorus content of 44 food products, including 30 refrigerated or frozen precooked meat, poultry, and fish items, generally national brands. OUTCOMES: Measured and reported phosphorus content of foods. MEASUREMENTS: Phosphorus by using Association of Analytical Communities official method 984.27; protein by using Association of Analytical Communities official method 990.03. RESULTS: We found that the ratio of phosphorus to protein content in these items ranged from 6.1 to 21.5 mg of phosphorus per 1 g of protein. The mean ratio in the 19 food products with a label listing phosphorus as an additive was 14.6 mg/g compared with 9.0 mg/g in the 11 items without listed phosphorus.

The objective of this study was to measure both total phosphorus (TP) and DP contents of selected foods and to compare the amounts of TP and DP and the proportion of DP to TP among different foods. METHODS: TP and DP content of 21 foods and drinks of plant origin were measured by inductively coupled plasma optical emission spectrometry. In DP analysis, samples were digested enzymatically in principle in the same way as in the alimentary canal before P analyses. The most popular national brands were chosen for analysis. RESULTS: The highest amount of TP (667 mg/100 g) was found in sesame seeds with hull, which also had the lowest percentage of DP (6%) to TP. Instead, in cola drinks and beer, the percentage of DP to TP was 87 to 100% (13 to 22 mg/100 g).

[ { "docid": "Ice_hockey", "text": "Ice hockey is a contact team sport played on ice , usually in a rink , in which two teams of skaters use their sticks to shoot a vulcanized rubber puck into their opponent 's net to score points . The sport is known to be fast-paced and physical , with teams usually consisting of six players each : one goaltender , and five players who skate up and down the ice trying to take the puck and score a goal against the opposing team . Ice hockey is most popular in Canada , central and eastern Europe , Scandinavia , and the northern regions of the United States . Ice hockey is the official national winter sport of Canada , where the modern version of the sport was created , and enjoys immense popularity ; alongside Canada , hockey is the most popular winter sport in Finland , Latvia , the Czech Republic , Sweden , Slovakia , Belarus and Switzerland . In North America , the National Hockey League ( NHL ) is the highest level for men 's hockey and the most popular . The Kontinental Hockey League ( KHL ) is the highest league in Russia and much of Eastern Europe . The International Ice Hockey Federation ( IIHF ) is the formal governing body for international ice hockey , with the IIHF managing international tournaments and maintaining the IIHF World Ranking . Worldwide , there are ice hockey federations in 74 countries . Ice hockey is believed to have evolved from simple stick and ball games played in the 18th and 19th century United Kingdom and elsewhere . These games were brought to North America and several similar winter games using informal rules were developed , such as `` shinny '' and `` ice polo '' . The contemporary sport of ice hockey was developed in Canada , most notably in Montreal , where the first indoor hockey game was played on March 3 , 1875 . Some characteristics of that game , such as the length of the ice rink and the use of a puck , have been retained to this day . Amateur ice hockey leagues began in the 1880s , and professional ice hockey originated around 1900 . The Stanley Cup , emblematic of ice hockey club supremacy , was first awarded in 1893 to recognize the Canadian amateur champion and later became the championship trophy of the NHL . In the early 1900s , the Canadian rules were adopted by the Ligue Internationale de Hockey sur Glace , the precursor of the IIHF and the sport was played for the first time in the Olympics in the Olympic Games of 1920 . In international competitions , the national teams of six countries ( the `` Big Six '' ) predominate : Canada , Czech Republic , Finland , Russia , Sweden and the United States . Of the 69 medals awarded all-time in men 's competition at the Olympics , only six medals were not awarded to one of those countries . In the annual Ice Hockey World Championships , 177 of 201 medals have been awarded to the six nations . Teams outside the `` Big Six '' have won only five medals in either competition since 1953 : All 12 Women 's Olympic and 36 IIHF World Women 's Championships medals have been awarded to one of these six countries , and every gold medal in both competitions has been won by either the Canadian national team or the United States national team . In Canada , the United States , and some European countries it is known simply as hockey ; the name `` ice hockey '' is used in places where `` hockey '' more often refers to field hockey , such as South America , Asia , Africa , Australasia , and some European countries . In Russia and Ukraine , where `` hockey '' can also refer to bandy , ice hockey is often called `` hockey with puck '' .", "title": "" } ]

Glycolytic metabolism is markedly accelerated in cancer cells, causing the accumulation of glucose (a reducing sugar) and methionine (an amino acid), which can non-enzymatically react and form carcinogenic substances. There is speculation that this reaction produces gaseous sulfur-containing compounds in tumour tissue. The aims of this study were to clarify the products in tumour and to investigate their effect on tumour proliferation. METHODS: Products formed in the reaction between glucose and methionine or its metabolites were analysed in vitro using gas chromatography. Flatus samples from patients with colon cancer and exhaled air samples from patients with lung cancer were analysed using near-edge x-ray fine adsorption structure spectroscopy and compared with those from healthy individuals. The tumour proliferation rates of mice into which HT29 human colon cancer cells had been implanted were compared with those of mice in which the cancer cells were surrounded by sodium hyaluronate gel to prevent diffusion of gaseous material into the healthy cells. RESULTS: Gaseous sulfur-containing compounds such as methanethiol and hydrogen sulfide were produced when glucose was allowed to react with methionine or its metabolites homocysteine or cysteine. Near-edge x-ray fine adsorption structure spectroscopy showed that the concentrations of sulfur-containing compounds in the samples of flatus from patients with colon cancer and in the samples of exhaled air from patients with lung cancer were significantly higher than in those from healthy individuals. Animal experiments showed that preventing the diffusion of sulfur-containing compounds had a pronounced antitumour effect. CONCLUSIONS: Gaseous sulfur-containing compounds are the main products in tumours and preventing the diffusion of these compounds reduces the tumour proliferation rate, which suggests the possibility of a new approach to cancer treatment.", "title": "Generation of gaseous sulfur-containing compounds in tumour tissue and suppression of gas diffusion as an antitumour treatment." }, { "docid": "MED-2240", "text": "Curcumin interacts with a large number of extra- and intracellular targets in a biphasic dose-dependent manner.

DESIGN: This was a prospective study of 23,363 men and women, aged 40-79 y, who were recruited in 1993-1997 and followed up to 2008. The baseline diet was assessed with food-frequency questionnaires. RESULTS: There were 3268 incident cancers after a mean follow-up of 11.4 y.

METHODS: Using four HPV(+) cervical cancer cell lines and normal fibroblasts we first tested the selectivity and potency of curcumin in eliminating HPV(+) cells. Subsequently, we developed a curcumin-based cervical cream and tested its efficacy in eliminating apposed HPV(+) cells and also its possible side effects on the vaginal epithelium of healthy mice. RESULTS: Curcumin selectively eliminates a variety of HPV(+) cervical cancer cells (HeLa, ME-180, SiHa, and SW756), suppresses the transforming antigen E6, dramatically inhibits the expression of the pro-cancer protein epidermal growth factor receptor (EGFR), and concomitantly induces p53. Additionally, Vacurin, a uniform colloidal solution of curcumin in a clinically used amphipathic vaginal cream, eliminates apposed HeLa cells while suppressing the expression of EGFR. In mice, daily intravaginal application of Vacurin for three weeks produced no change in body weight and when the mice were sacrificed, the vaginal tract epithelium showed no Vacurin-evoked adverse effects. CONCLUSION: We have developed a curcumin-based vaginal cream, which effectively eradicates HPV(+) cancer cells and does not affect non-cancerous tissue. Our preclinical data support a novel approach for the treatment of cervical HPV infection. Copyright © 2012 Elsevier Inc.

Restriction of methionine may be an important strategy in cancer growth control particularly in cancers that exhibit dependence on methionine for survival and proliferation. Methionine dependence in cancer may be due to one or a combination of deletions, polymorphisms or alterations in expression of genes in the methionine de novo and salvage pathways. Cancer cells with these defects are unable to regenerate methionine via these pathways. Defects in the metabolism of folate may also contribute to the methionine dependence phenotype in cancer. Selective killing of methionine dependent cancer cells in co-culture with normal cells has been demonstrated using culture media deficient in methionine. Several animal studies utilizing a methionine restricted diet have reported inhibition of cancer growth and extension of a healthy life-span. In humans, vegan diets, which can be low in methionine, may prove to be a useful nutritional strategy in cancer growth control. The development of methioninase which depletes circulating levels of methionine may be another useful strategy in limiting cancer growth. The application of nutritional methionine restriction and methioninase in combination with chemotherapeutic regimens is the current focus of clinical studies. Copyright © 2012 Elsevier Ltd.

Several research studies have provided in-depth analysis of multiple targets through which curcumin induces protective effects against cancers including gastrointestinal, genitourinary, gynecological, hematological, pulmonary, thymic, brain, breast, and bone. The molecular mechanisms of action of curcumin in treating different types of cancers remain under investigation. The multifaceted role of this dietary agent is mediated through its inhibition of several cell signaling pathways at multiple levels. Curcumin has the ability to inhibit carcinogenicity through the modulation of the cell cycle by binding directly and indirectly to molecular targets including transcription factors (NF-kB, STAT3, β-catenin, and AP-1), growth factors (EGF, PDGF, and VEGF), enzymes (COX-2, iNOS, and MMPs), kinases (cyclin D1, CDKs, Akt, PKC, and AMPK), inflammatory cytokines (TNF, MCP, IL-1, and IL-6), upregulation of proapoptotic (Bax, Bad, and Bak) and downregulation of antiapoptotic proteins (Bcl(2) and Bcl-xL).

Dietary/lifestyle patterns were created using principal component analysis (PCA). Impact of the resultant scores on cancer risk was estimated through logistic regression. Results PCA identified six patterns: meat/nitrite, fruit/vegetable, smoking/alcohol, legume/meat alternate, GERD/BMI, and fish/vitamin C. Risk of each cancer under study increased with rising meat/nitrite score. Risk of EA increased with increasing GERD/BMI score, and risk of ESCC rose with increasing smoking/alcohol score and decreasing GERD/BMI score.

Previous reports have suggested an association between gout and kidney stone disease; however, these studies did not adjust for such important potential confounders as obesity and the presence of hypertension. To our knowledge, no published study has examined the independent association between gout and kidney stone disease. METHODS: We used a national probability sample of the US population to determine the independent association between reported gout and history of kidney stone disease. RESULTS: Among men and women 20 years and older, 5.6% (10 million) reported the previous passage of a kidney stone and 2.7% (5.1 million) reported a diagnosis of gout by a physician. Moreover, 8.6% of individuals who reported the passage of a kidney stone on two or more occasions had a history of gout. Conversely, the prevalence of previous kidney stones in subjects with reported gout was 13.9%. In the age-adjusted model, gout was associated with an increased odds ratio (OR) for previous kidney stones (OR, 1.97; 95% confidence interval [CI], 1.37 to 2.83). After further adjustment for sex, race, body mass index, and presence of hypertension, the OR for previous kidney stones in individuals with gout decreased to 1.49 (95% CI, 1.04 to 2.14).

In this study, steady-state levels of markers of different kinds of protein damage--oxidation (glutamic and aminoadipic semialdehydes), mixed glyco- and lipoxidation (carboxymethyl- and carboxyethyllysine), lipoxidation (malondialdehydelysine) and amino acid composition--were measured in the heart of eight mammalian species ranging in maximum life span (MLSP) from 3.5 to 46 years. Oxidation markers were directly correlated with MLSP across species. Mixed glyco- and lipoxidation markers did not correlate with MLSP. However, the lipoxidation marker malondialdehydelysine was inversely correlated with MLSP (r2=0.85; P<0.001). The amino acid compositional analysis revealed that methionine is the only amino acid strongly correlated MLSP and that such correlation is negative (r2=0.93; P<0.001). This trait may contribute to lower steady-state levels of oxidized methionine residues in cellular proteins.

The development of a novel screening method that is as economical and non-invasive as the faecal occult blood test (FOBT) for early detection of colorectal cancer (CRC) is needed. A study was undertaken using canine scent detection to determine whether odour material can become an effective tool in CRC screening. Design Exhaled breath and watery stool samples were obtained from patients with CRC and from healthy controls prior to colonoscopy. Each test group consisted of one sample from a patient with CRC and four control samples from volunteers without cancer. These five samples were randomly and separately placed into five boxes. A Labrador retriever specially trained in scent detection of cancer and a handler cooperated in the tests. The dog first smelled a standard breath sample from a patient with CRC, then smelled each sample station and sat down in front of the station in which a cancer scent was detected. Results 33 and 37 groups of breath and watery stool samples, respectively, were tested. Among patients with CRC and controls, the sensitivity of canine scent detection of breath samples compared with conventional diagnosis by colonoscopy was 0.91 and the specificity was 0.99. The sensitivity of canine scent detection of stool samples was 0.97 and the specificity was 0.99. The accuracy of canine scent detection was high even for early cancer. Canine scent detection was not confounded by current smoking, benign colorectal disease or inflammatory disease. Conclusions This study shows that a specific cancer scent does indeed exist and that cancer-specific chemical compounds may be circulating throughout the body.

However, it is not known whether methionine dependence occurs in fresh patient tumors as it does in cell lines. In order to determine whether methionine dependence occurs in fresh patient tumors as well as whether methionine dependence occurs in fresh patient tumors as well as in cell lines we took advantage of the technique of sponge-gel-supported histoculture to grow tumors directly from surgery. We then measured nuclear DNA content by image analysis to determine the cell cycle position in MET-HCY+ compared to MET+HCY- medium in 21 human patient tumors. Human tumor cell lines found to be methionine dependent by cell count were used as positive controls and were found to have marked reduction of cells in G1 compared to total cells in the cell cycle in MET-HCY+ medium with respect to the G1: total cell ratio in MET+HCY- medium. Therefore late cell cycle arrest was used as a marker of methionine dependence for histocultured patient tumors. We found that 5 human tumors of 21, including tumors of the colon, breast, ovary, prostate, and a melanoma, were methionine dependent based on cell cycle analysis.

Since then, ten prospective studies have published new results. Here we update the evidence from prospective studies and explore whether there is a non-linear association of red and processed meats with colorectal cancer risk. Methods and Findings Relevant prospective studies were identified in PubMed until March 2011. For each study, relative risks and 95% confidence intervals (CI) were extracted and pooled with a random-effects model, weighting for the inverse of the variance, in highest versus lowest intake comparison, and dose-response meta-analyses. Red and processed meats intake was associated with increased colorectal cancer risk. The summary relative risk (RR) of colorectal cancer for the highest versus the lowest intake was 1.22 (95% CI  = 1.11−1.34) and the RR for every 100 g/day increase was 1.14 (95% CI  = 1.04−1.24). Non-linear dose-response meta-analyses revealed that colorectal cancer risk increases approximately linearly with increasing intake of red and processed meats up to approximately 140 g/day, where the curve approaches its plateau. The associations were similar for colon and rectal cancer risk. When analyzed separately, colorectal cancer risk was related to intake of fresh red meat (RR for 100 g/day increase  = 1.17, 95% CI  = 1.05−1.31) and processed meat (RR for 50 g/day increase  = 1.18, 95% CI  = 1.10−1.28).

The aim in this trial was to assess the efficacy of curcumin as maintenance therapy in patients with quiescent ulcerative colitis (UC). METHODS: Eighty-nine patients with quiescent UC were recruited for this randomized, double-blind, multicenter trial of curcumin in the prevention of relapse. Forty-five patients received curcumin, 1g after breakfast and 1g after the evening meal, plus sulfasalazine (SZ) or mesalamine, and 44 patients received placebo plus SZ or mesalamine for 6 months. Clinical activity index (CAI) and endoscopic index (EI) were determined at entry, every 2 months (CAI), at the conclusion of 6-month trial, and at the end of 6-month follow-up. RESULTS: Seven patients were protocol violators. Of 43 patients who received curcumin, 2 relapsed during 6 months of therapy (4.65%), whereas 8 of 39 patients (20.51%) in the placebo group relapsed (P=.040). Recurrence rates evaluated on the basis of intention to treat showed significant difference between curcumin and placebo (P=.049). Furthermore, curcumin improved both CAI (P=.038) and EI (P=.0001), thus suppressing the morbidity associated with UC.

Chitin is an eukaryotic extracellular aminosugar biopolymer, massively produced by most fungal systems and by invertebrates, notably arthropods. Being an integral supportive component in fungal cell wall, insect cuticle, and nematode egg shell, chitin has been considered as a selective target for pesticide action. Throughout the elaborate processes of chitin formation and deposition, only the polymerization events associated with the cell membrane compartment are so far available for chemical interference. Currently, the actinomycetes-derived nucleoside peptide fungicides such as the polyoxins and the insecticidal benzoylaryl ureas have reached commercial pesticide status. The polyoxins and other structurally-related antibiotics like nikkomycins are strong competitive inhibitors of the polymerizing enzyme chitin synthase. The exact biochemical lesion inflicted by the benzoylaryl ureas is still elusive, but a post-polymerization event, such as translocation of chitin chains across the cell membrane, is suggested. Hydrolytic degradation of the chitin polymer is essential for hyphal growth, branching, and septum formation in fungal systems as well as for the normal molting of arthropods. Recently, insect chitinase activity was strongly and specifically suppressed by allosamidin, an actimomycetes-derived metabolite. In part, the defense mechanism in plants against invasion of pathogens is associated with induced chitinases. Chitin, chitosan, and their oligomers are able to act as elicitors which induce enhanced levels of chitinases in various plants.

On the other hand, many studies have consistently shown that dietary restriction (DR) in rodents also decreases mitochondrial ROS (mtROS) production and oxidative damage to mitochondrial DNA and proteins. It has been observed that protein restriction also decreases mtROS generation and oxidative stress in rat liver, whereas neither carbohydrate nor lipid restriction change these parameters. This is interesting because protein restriction also increases maximum longevity in rodents (although to a lower extent than DR) and is a much more practicable intervention for humans than DR, whereas neither carbohydrate nor lipid restriction seem to change rodent longevity. Moreover, it has been found that isocaloric methionine restriction also decreases mtROS generation and oxidative stress in rodent tissues, and this manipulation also increases maximum longevity in rats and mice. In addition, excessive dietary methionine also increases mtROS generation in rat liver. These studies suggest that the reduced intake of dietary methionine can be responsible for the decrease in mitochondrial ROS generation and the ensuing oxidative damage that occurs during DR, as well as for part of the increase in maximum longevity induced by this dietary manipulation. In addition, the mean intake of proteins (and thus methionine) of Western human populations is much higher than needed.

OBJECTIVES: To assess the effectiveness of cranberry products in preventing UTIs in susceptible populations. SEARCH STRATEGY: We searched MEDLINE, EMBASE, the Cochrane Central Register of Controlled Trials (CENTRAL in The Cochrane Library) and the Internet. We contacted companies involved with the promotion and distribution of cranberry preparations and checked reference lists of review articles and relevant studies. Date of last search: January 2007. SELECTION CRITERIA: All randomised controlled trials (RCTs) or quasi-RCTs of cranberry products for the prevention of UTIs in all populations. DATA COLLECTION AND ANALYSIS: Two authors independently assessed and extracted information. Information was collected on methods, participants, interventions and outcomes (UTIs - symptomatic and asymptomatic, side effects, adherence to therapy). Relative risk (RR) were calculated where appropriate, otherwise a narrative synthesis was undertaken. Quality was assessed using the Cochrane criteria. MAIN RESULTS: Ten studies (n = 1049, five cross-over, five parallel group) were included. Cranberry/cranberry-lingonberry juice versus placebo, juice or water was evaluated in seven studies, and cranberries tablets versus placebo in four studies (one study evaluated both juice and tablets). Cranberry products significantly reduced the incidence of UTIs at 12 months (RR 0.65, 95% CI 0.46 to 0.90) compared with placebo/control. Cranberry products were more effective reducing the incidence of UTIs in women with recurrent UTIs, than elderly men and women or people requiring catheterisation. Six studies were not included in the meta-analyses due to methodological issues or lack of available data. However, only one reported a significant result for the outcome of symptomatic UTIs. Side effects were common in all studies, and dropouts/withdrawals in several of the studies were high. AUTHORS' CONCLUSIONS: There is some evidence that cranberry juice may decrease the number of symptomatic UTIs over a 12 month period, particularly for women with recurrent UTIs. It's effectiveness for other groups is less certain. The large number of dropouts/withdrawals indicates that cranberry juice may not be acceptable over long periods of time.

Subsequent reports of decreased systolic function, heart failure, and leukemia prompted the US Food and Drug Administration to institute a “black box” warning in 2005. This review was undertaken to examine the available literature on the efficacy and safety of mitoxantrone use in patients with MS since the initial report. Methods: Relevant articles were obtained through a review of the medical literature and the strength of the available evidence was graded according to the American Academy of Neurology evidence classification scheme. Results: The accumulated Class III and IV evidence suggests an increased incidence of systolic dysfunction and therapy-related acute leukemia (TRAL) with mitoxantrone therapy. Systolic dysfunction occurs in ∼12% of patients with MS treated with mitoxantrone, congestive heart failure occurs in ∼0.4%, and leukemia occurs in ∼0.8%.

To test this hypothesis, IGF-I was restored during DR to ascertain if lowering of IGF-I was central to slowing bladder cancer progression during DR. Heterozygous p53-deficient mice received a bladder carcinogen, p-cresidine, to induce preneoplasia. After confirmation of bladder urothelial preneoplasia, the mice were divided into three groups: (a) ad libitum; (b) 20% DR; and (c) 20% DR plus IGF-I (IGF-I/DR).

Telomere shortness in human beings is emerging as a prognostic marker of disease risk, progression, and premature mortality in many types of cancer, including breast, prostate, colorectal, bladder, head and neck, lung, and renal cell. Telomere shortening is counteracted by the cellular enzyme telomerase. Lifestyle factors known to promote cancer and cardiovascular disease might also adversely affect telomerase function. However, previous studies have not addressed whether improvements in nutrition and lifestyle are associated with increases in telomerase activity. We aimed to assess whether 3 months of intensive lifestyle changes increased telomerase activity in peripheral blood mononuclear cells (PBMC). METHODS: 30 men with biopsy-diagnosed low-risk prostate cancer were asked to make comprehensive lifestyle changes. The primary endpoint was telomerase enzymatic activity per viable cell, measured at baseline and after 3 months. 24 patients had sufficient PBMCs needed for longitudinal analysis. This study is registered on the ClinicalTrials.gov website, number NCT00739791. FINDINGS: PBMC telomerase activity expressed as natural logarithms increased from 2.00 (SD 0.44) to 2.22 (SD 0.49; p=0.031). Raw values of telomerase increased from 8.05 (SD 3.50) standard arbitrary units to 10.38 (SD 6.01) standard arbitrary units. The increases in telomerase activity were significantly associated with decreases in low-density lipoprotein (LDL) cholesterol (r=-0.36, p=0.041) and decreases in psychological distress (r=-0.35, p=0.047). INTERPRETATION: Comprehensive lifestyle changes significantly increase telomerase activity and consequently telomere maintenance capacity in human immune-system cells. Given this finding and the pilot nature of this study, we report these increases in telomerase activity as a significant association rather than inferring causation.

METHODS: Standardized mortality ratios (SMRs) and proportional mortality ratios (PMRs) were estimated for each cohort as a whole and in subgroups defined by race and sex, using the US general population mortality rates for comparison. Study subjects were followed up from January 1950 to December 2006, during which time over 60% of them died. RESULTS: An excess of deaths from cancers of the base of the tongue, esophagus, lung, skin, bone and bladder, lymphoid leukemia, and benign tumors of the thyroid and other endocrine glands, and possibly Hodgkin's disease, was observed in abattoir and meat processing workers. Significantly lower SMRs were recorded for cancer of the thymus, mediastinum, pleura, etc., breast cancer, and non-Hodgkin's lymphoma.

However, talk to your bank. Is it worth getting something by a lawyer? Definitely, you need a lawyer and so do your parents. There is a general presumption at law that arrangements between family members are not meant to be contracts. You definitely want this to be a contract and engaging lawyers will make sure that it is. You also definitely want this to be a proper mortgage so that you get first call on the property should your parents die or go bankrupt. In addition, a lawyer will be able to advise you of the pitfalls that you haven't seen. If both of my parents were to pass away before the money is returned, would that document be enough to ensure that the loan is returned promptly? No, see above. Tax implications: Will this count as taxable income for me? And if so, presumably my parents can still count it as a tax deduction? Definitely, however the ATO is very keen that these sorts of arrangements do not result in tax minimisation. Your parents will get a deduction at the rate charged; you will pay tax on the greater of the rate charged or a fair commercial rate i.e. what your parents would be paying a bank. For example, if the going bank mortgage rate is 5.5% and you charged 2% they get the deduction for 2%, you pay tax as though they had paid 5.5%.

(I could of course double down and pay their monthly repayments for them in this case). First, property prices collapsing have no impact on whether your parents can pay the loan. If they can it doesn't matter what the property is worth. If they can't then it will be sold as quickly as possible for an amount that covers (as far as possible) the first mortgagee's indebtedness.

This is what happens when you calculate the taxes using a generic tax calculator, however, the theory breaks down in certain cases. If you are earning less than $100k there is very little difference and paying out a salary is usually the better option. In a large stable company the most efficient option is almost always a mix of both. If you are earning more than $100k a year it depends on a number of factors: 1) Are your companies annual earnings over $500,000? In Canada, private companies that earn more than $500,000 annually are taxed at a higher rate than those earning less than $500,000. If the earnings are above $500,000 generally you should reduce the earning to under $500,000 by paying a salary. However, this depends on the province, the other income of the owners are and how much more than $500,000 your company earns. 2) Are you eligible for deductions or benefits only available on earned income? Earned income is income that you have worked for, which does not include dividends. RRSP contribution room, child care expense deductions, CPP, and many other benefits under the CRA rules are only available to people who have an earned income. It is worth taking advantage of these deductions when they are available. 3) Is your company eligible for any tax deductions? The same as with your personal tax deductions and your personal benefits of earning income, having a corporate income is also a benefit. There are a number of tax credits and tax deductions that corporations can take advantage of and when available these should be taken advantage of before paying everything out in salary. Once all these questions are answered the calculation is based on your marginal tax rate and the tax rate of the Corporation. One other reason to have at least a portion of you salary as a dividend is that if you incur capital loss in your corporation you can pass them to your personal taxes. If you were payed 100% in salary this does not work. Other strategies to be more tax efficient: Income splitting (Pay a salary/dividend to yourself, your wife, your children your parents, or anyone you support).

One single month of no revenue doesn't mean much in that annual scheme of things. Total annual revenue and total annual expenses are what impact the results. In other words, yes, your corporation can book revenues in (say) 11 of 12 months of the year but still incur expenses in all months. Many seasonal businesses operate this way and it is perfectly normal. You could even just have, say, one super-awesome month and spend money the rest of the year. Heck, you could even have zero revenue but still incur expenses—startups often work like that at first. (You'd need investment funding, personal credit, a loan, or retained earnings from earlier profitable periods to do that, of course.) As long as your corporation has a reasonable expectation of a profit and the expenses your corporation incurs are valid business expenses, then yes, you ought to be able to deduct those expenses from your revenue when figuring taxes owed, regardless of whether the expenses were incurred at the same approximate time as revenue was booked—as long as the expense wasn't the acquisition of a depreciable asset. Some things your company would buy—such as the computer in your example—would not be fully deductible in the year the expense is incurred. Depreciable property expenses are deducted over time according to a schedule for the kind of property. The amount of depreciation expense you can claim for such property each year is known as Capital Cost Allowance. A qualified professional accountant can help you understand this. One last thing: You wrote \"\"write off\"\". That is not the same as \"\"deduct\"\". However, you are forgiven, because many people say \"\"write off\"\" when they actually mean \"\"deduct\"\" (for tax purposes). \"\"Write off\"\", rather, is a different accounting term, meaning where you mark down the value of an asset (e.g. a bad loan that will never be repaid) to zero; in effect, you are recognizing it is now a worthless asset. There can be a tax benefit to a write-off, but what you are asking about are clearly expense deductions and not write-offs.

So, yeah, your tax bill is lower, but 3-4 times that amount is going out the door in interest. Plus, when you buy a property, you may have substantial taxes on that property that your landlord is paying now. Secondly, yes, you can deduct expenses on a business, but that only can be done without income for so long before the IRS begins disallowing your deductions. But if you're making money, the expenses come right off of your income. Third, owning a business means that you get the privilege of paying a self-employment tax, which is the same thing that your employer now pays into Social Security on your behalf. More taxes!

This applies to both traditional IRAs and 401Ks. Roth accounts have different rules but valuable benefits. My effective income tax rate is around 35%.

Since my 401K contributions are deferred reductions from my income I can invest 35% more money into my 401K than I would be able to invest in a non-tax-advantaged account. Where I can invest $1000 into my 401K I would only be able to invest $650 into a non-advantaged account with the same wages. If I put $650 into an account yielding 10% then my one-year return on my income is $65 The 10% return on my $1000 is $100. Compared to what I would have been able to take home in the first place this makes my ROI $100/$650 = 15.3% Interest earned in non-advantaged accounts incurs taxes every year. Interest earned in advantaged accounts does not incur taxes until withdrawn. Compounding 10% annually for 20 years is significantly more than 6.5% compounded annually for 20 years. Imagine 10% on a 1000 investment with no additional cash flows over 20 year. The result is $6727, or 672%. Imagine your income tax rate does not reduce below 35%, your after-tax return is 4372, or %437 return. Now imagine you pay taxes every year on 10% take, so your take annually is only 6.5%...

Less of a gain, but still a gain. In fact your capital-gains rate would have to be as low as 22% to even this difference out (versus a 35% income tax rate).... And remember that this assumes you're in the same bracket at retirement (which more people are not) You may also note that I used $1000 as the principle in both calculations.

They are for things like public housing and other urban projects. They are tax free for everyone but only rich people buy them. Why? The issue is that the tax free nature of the bond is included in its yield. So rather than yielding say a 5% return, they figure that the owner is getting 20% off due to not paying taxes. As a result, they only give a 4% return but are as risky as a 5% return investment. Net result, only rich people invest in tax free bonds. \"\"Rich\"\" is defined here to mean people paying a 20% tax on long term investment returns. Or take the State and Local Tax (SALT) deduction, which has been in the news recently. Again, it is technically open to everyone. But there is also a standard deduction that is open to everyone. For the typical family, state and local taxes might be 5% of income. So for a family making $100k a year, that's $5k. The same family can take a $13k or so standard deduction instead of itemizing. So why would they take the smaller deduction? As a practical matter, two groups take the SALT deduction. People rich enough to pay more than $13k in state and local taxes and people who also take the mortgage interest deduction. So it helps a lot of people who are rich quite a bit. And it helps a few middle class people some. But if you are lower middle class with a $30k mortgage on a tiny house and paying 4% interest, then that's only $1200 a year. Add in property taxes of $3000 and SALT of $2.8k and that's only $7k. Even if the person gives $3k to charity, the $13k deduction is a lot better and requires less paperwork. Contrast that with someone who has $500k mortgage at 3.6% interest. That's $18k in interest alone. Add in a SALT of $7k and property taxes of $50k, and there's $75k of itemized deductions, much better than $13k. Now a $7k donation to charity is entirely deductible.

You may end up in the 12% bracket in New York City or around 10% in California or other \"\"bad\"\" income-tax states. But Alberta is considered a tax haven in Canada and has a 10% flat tax. Ontario's top rate is about 11%, but there are surtaxes that can push the effective rate to about 17%. Investment income taxes: Canada wins, narrowly. Income from capital gains counts as half, so if you're very rich and live in Ontario, your rate is about 23% and less than that in Alberta. The only way to match or beat this deal in the US in the long term is to live in a no-income-tax state. Dividends are taxed at rates somewhere between capital gains and ordinary income - not as good a deal as Bush's 15% rate on preferred dividends, but that 15% rate will probably expire soon. Sales taxes: US wins, but the gap is closing. Canada has a national VAT-like tax, called GST and its rate came down from 7% to 5% when Harper became the Prime Minister. Provinces have sales taxes on top of that, in the range of 7-8% (but Alberta has no sales tax). Some provinces \"\"harmonized\"\" their sales taxes with the GST and charge a single rate, e.g. Ontario has a harmonized sales tax (HST) of 13% (5+8). 13% is of course a worse rate than the 6-8% charged by most states, but then some states and counties already charge 10% and the rates have been going up in each recession. Payroll taxes: much lower in Canada. Canadian employees' CPP and EI deductions have a low threshold and top out at about $3,000. Americans' 7.65% FICA rate applies to even $100K, resulting in a tax of $7,650. Property taxes: too dependent on the location, hard to tell. Tax benefits for retirement savings: Canada. If you work in the US and don't have a 401(k), you get a really bad deal: your retirement is underfunded and you're stuck with a higher tax bill, because you can't get the deduction. In Canada, if you don't have an RRSP at work, you take the money to the financial company of your choice, invest it there, and take the deduction on your taxes. If you don't like the investment options in your 401(k), you're stuck with them. If you don't like them in your RRSP, contribute the minimum to get the match and put the rest of the money into your individual RRSP; you still get the same deduction. Annual 401(k) contribution limits are use-it-or-lose-it, while unused RRSP limits and deductions can be carried forward and used when you need to jump tax brackets. Canada used to lack an answer to Roth IRAs, but the introduction of TFSAs took care of that. Mortgage interest deduction: US wins here as mortgage interest is not deductible in Canada.

You plug your donations into line 4, then the worksheet grinds through all the math and shows what part you deduct this year and what part you carryover to the next year. *** I specifically asked managers at two DAFs whether they were OK with someone donating a complex asset to the DAF, and immediately giving the entire cash amount to a charity. The DAF doesn't get any fees if you do that. They said not only are they OK with it, most of their donors do exactly that and most DAF accounts are empty. They make it on the 0.6% a year custodial fee on the other accounts, and charitable giving to them. Mind you, you can only donate to 501C3 type charities, what IRS calls \"\"50% limit organizations\"\". This actually protects you from donating to organizations who lie about their status. **** I'm not with Fidelity, but I am a satisfied DAF customer. The DAF funds its overhead by deducting 0.6% per year from your giving account.

On the bright side, you don't have to pay rent out of the .008N. You still need housing out of the .036N without the house. These formulas should be considered examples. I don't know how much your property taxes might be. Nor do I know how much you'll pay in taxes. Heck, I don't know that you'll average a 5% return after inflation. You may have to put some of the money into cash equivalents with negligible return. But this should allow you to research more what your situation really is. If we set returns to 3.5% after inflation and 2.4% after inflation and taxes, that changes the numbers slightly but importantly. The \"\"no house\"\" number becomes .024N. The \"\"with house\"\" number becomes So that's $24,000 (which needs to include rent) versus -$800 (no rent needed). There is not enough money in that plan to have any remainder to live on in the \"\"with house\"\" option. Given the constraints for N and these assumptions about returns, you would be $800 to $8000 short every year. This continues to assume that property taxes are 10% of the property value annually. Lower property taxes would of course make this better. Higher property taxes would be even less feasible. When comparing to people with homes, remember the option of selling the home. If you sell your .2N home for .2N and buy a .08N condo instead, that's not just .12N more that is invested. You'll also have less tied up with property taxes. It's a lot easier to live on $20k than $8k. Or do a reverse mortgage where the lender pays the property taxes. You'll get some more savings up front, have a place to live while you're alive, and save money annually.

If your parents give you cash to buy a home, you use it for a cash sale, and you then repay them, then if they don't charge you interest (above and beyond any they may pay - treat their loan as entirely separate from yours.) that amount of not-charged interest is considered a gift. You can look up these rates here, on the IRS website, called \"\"Applicable Federal Rates\"\"; currently it's around 2.30% APR. If the interest is that much, the interest isn't a gift, but part of a loan - though your parents will have to file some paperwork and you will also. Search for more information about \"\"Intra-Family Loans\"\" for full details - and talk to a real estate lawyer. Separately, if your parents are the primary/only signors on the mortgage, and are thus effectively the property owner, there are two separate issues. First, you're welcome to pay off the mortgage while you live there, and no tax issues exist (then) in terms of gift, though it's still owned in your parents' name - so you don't get the house, they'd have to gift that to you separately, though they can do that in stages to avoid gift tax ($14k worth of equity per year, or whatever the current year's annual limit is, per parent and per you/wife if applicable).

In general, there are a lot of options for exactly how you structure the purchase, payments, and equity, and you should talk to a professional to find out exactly the right way to structure it. This mortgage info site has some good tips for several different ways to structure things, just as an example. I would in particular suggest you pay attention to deductability of mortgage interest and property taxes, as those two can be a huge amount of tax savings and you can lose that very easily if you're not careful.\"", "title": "" }, { "docid": "245447", "text": "\"For simplicity, let's start by just considering cash back. In general, cash back from credit cards for personal use is not taxable, but for business use it is taxable (sort of, I'll explain later). The reason is most personal purchases are made with after tax dollars; you typically aren't deducting the cost of what you purchased from your personal income, so if you purchase something that costs $100 and you receive $2 back from the CC company, effectively you have paid $98 for that item but that wouldn't affect your tax bill. However, since businesses typically deduct most expenses, that same $100 deduction would have only been a $98 deduction for business tax purposes, so in this case the $2 should be accounted for. Note, you should not consider that $2 as income though; that would artificially inflate your revenue. It should be treated as a negative expense, similar to how you would handle returning an item you purchased and receiving a CC refund. Now for your specific questions: Part 1: As a small business owner, I wish to attend an annual seminar to improve my business. I have enough credit card reward points to cover the airfare, hotel, and rental car. Will those expenses still be deductible at the value displayed on the receipt? Effectively no, these expenses are not deductible. If you deduct them they will be completely counter-acted by the \"\"refund\"\" you receive for the payments. Part 2: Does it matter if those points are accrued on my personal credit card, rather than a business credit card? This is where it gets hairy. Suppose your company policy is that employees make purchases with their own personal credit cards and submit receipts for reimbursement. In this case the employer can simply reimburse and would not know or care if the employee is racking up rewards/points/cashback. The trick is, as the employee, you must always purchase business related items normally so you have receipts to show, and if you receive cashback on the side there seems to be a \"\"don't ask, don't tell\"\" rule that the IRS is OK with. It works the same way with heavy business travelers and airline miles- the free vacations those users get as perks are not treated as taxable income. However, I would not go out of my way to abuse this \"\"loophole\"\". Typically, things like travel (airfare, hotel, car rental, meals) are expected. But I wouldn't go purchase 100 company laptops on your personal card and ask the company to reimburse you. The company should purchase those 100 laptops on a company card and effectively reduce the sale price by the cashback received. (Or more realistically, negotiate a better discount with your account rep and just cut them a check.) Part 3: Would there be any difference between credit card points and brand-loyalty points? If the rental car were paid for with points earned directly on the rental car company's loyalty system (not a CC), would that yield a different result? There is no difference. Perhaps the simplest way to think about this is you can only deduct an expense that you actually incur. In other words, the expense should show up on a bank or CC statement. This is why when you volunteer and work 10 hours for a charity, you can't call that a \"\"donation\"\" of any amount of money because there is no actual payment made that would show up on a bank statement. Instead you could have billed the charity for your 10 hours of work, and then turned around and donated that same amount back to them, but it ends up being a wash.\"", "title": "" }, { "docid": "141738", "text": "\"About deducting mortgage interest: No, you can not deduct it unless it is qualified mortgage interest. \"\"Qualified mortgage interest is interest and points you pay on a loan secured by your main home or a second home.\"\" (Tax Topic 505).

Estate taxes are paid by the estate of the decedent, not by the beneficiaries, and so you do not owe any estate tax. As a matter of fact, most estates in the US do not pay Federal estate tax at all because only the amount that exceeds the Federal exemption ($5.5M) is taxable, and most estates are smaller. State estate taxes might be a different matter because while many states exempt exactly what the Federal Government does, others exempt different (usually smaller) amounts. But in any case, estate taxes are not of concern to you except insofar as what you inherit is reduced because the estate had to pay estate tax before distributing the inheritances. As JoeTaxpayer's answer says more succinctly, what you inherit is net of estate tax, if any. What you receive as an inheritance is not taxable income to you either. If you receive stock shares or other property, your basis is the value of the property when you inherit it. Thus, if you sell at a later time, you will have to pay taxes only on the increase in the value of the property from the time you inherit it. The increase in value from the time the decedent acquired the property till the date of death is not taxable income to you. Exceptions to all these favorable rules to you is the treatment of Traditional IRAs, 401ks, pension plans etc that you inherit that contain money on which the decedent never paid income tax. Distributions from such inherited accounts are (mostly) taxable income to you; any part of post-tax money such as nondeductible contributions to Traditional IRAs that is included in the distribution is tax-free. Annuities present another source of complications. For annuities within IRAs, even the IRS throws up its hands at explaining things to mere mortals who are foolhardy enough to delve into Pub 950, saying in effect, talk to your tax advisor. For other annuities, questions arise such as is this a tax-deferred annuity and whether it was purchased with pre-tax money or with post-tax money, etc. One thing that you should check out is whether it is beneficial to take a lump sum distribution or just collect the money as it is distributed in monthly, quarterly, semi-annual, or annual payments. Annuities in particular have heavy surrender charges if they are terminated early and the money taken as a lump sum instead of over time as the insurance company issuing the annuity had planned on happening. So, taking a lump sum would mean more income tax immediately due not just on the lump sum but because the increase in AGI might reduce deductions for medical expenses as well as reduce the overall amount of itemized deductions that can be claimed, increase taxability of social security benefits, etc. You say that you have these angles sussed out, and so I will merely re-iterate Beware the surrender charges.", "title": "" }, { "docid": "257703", "text": "\"How can I avoid this, so we are taxed as if we are making the $60k/yr that we want to receive?

Each county assessor's office reviews all recorded deeds for that county to determine which properties require reappraisal under the law. The county assessors may also discover changes in ownership through other means, such as taxpayer self-reporting, field inspections, review of building permits and newspapers. Once the county assessor has determined that a change in ownership has occurred, Proposition 13 requires the county assessor to reassess the property to its current fair market value as of the date ownership changed. Since property taxes are based on the assessed value of a property at the time of acquisition, a current market value that is higher than the previously assessed Proposition 13 adjusted base year value will increase the property taxes. Conversely, if the current market value is lower than the previously assessed Proposition 13 adjusted base year value, then the property taxes on that property will decrease. Only that portion of the property that changes ownership, however, is subject to reappraisal. For example, if 50 percent of the property is transferred, the assessor will reassess only 50 percent of the property at its current fair market value as of the date of the transfer, and deduct 50 percent from any existing Proposition 13 base year value.

First, you need to understand that there will be taxes withheld from your paycheck, but the amount that they withhold is simply a guess. You might pay too much or too little tax during the year. After the year is over, you'll send in a tax return form that calculates the correct tax amount. If you have paid too little over the year, you'll have to send in the rest, but if you've paid too much, you'll get a refund. There are complicated formulas on how much tax the employer withholds from your paycheck, but in general, if you don't have extra income elsewhere that you need to pay tax on, you'll probably be close to breaking even at tax time. When you get your paycheck, the first thing that will be taken off is FICA, also called Social Security, Medicare, or the Payroll tax. This is a fixed 7.65% that is taken off the gross salary. It is not refundable and is not affected by any allowances or deductions, and does not come in to play at all on your tax return form. There are optional employee benefits that you might need to pay a portion of if you are going to take advantage of them, such as health insurance or retirement savings. Some of these deductions are paid with before-tax money, and some are paid with after tax money. The employer will calculate how much money they are supposed to withhold for federal and state taxes (yes, California has an income tax), and the rest is yours. At tax time, the employer will give you a form W-2, which shows you the amount of your gross income after all the before-tax deductions are taken out (which is what you use to calculate your tax). The form also shows you how much tax you have paid during the year. Form 1040 is the tax return that you use to calculate your correct tax for the year. You start with the gross income amount from the W-2, and the first thing you do is add in any income that you didn't get a W-2 for (such as interest or investment income) and subtract any deductions that you might have that are not taxable, but were not paid through your paycheck (such as moving expenses, student loan interest, tuition, etc.) The result is called your adjusted gross income. Next, you take off the deductions not covered in the above section (property tax, home mortgage interest, charitable giving, etc.). You can either take the standard deduction ($6,300 if you are single), or if you have more deductions in this category than that, you can itemize your deductions and declare the correct amount.

You can brag about it at parties if the share price has gone up, or weep bitter tears into your cocktail if the price has gone down, but the IRS not only does not care, but it will not let you deduct the paper loss or pay taxes on the paper gain. What you put down on Form 1040 Schedules B and D is precisely what the mutual fund will tell you on Form 1099-DIV (and Form 1099-B), no more, no less. If you did not report any of these amounts on your previous tax returns, you need to file amended tax returns, both Federal as well as State, A stock mutual fund invests in stocks and the fund manager may buy and sell some stocks during the course of the year.

This capital gain distribution is reported to you on Form 1099-DIV and you have to report sit on your tax return even if you re-invested in more share of the same mutual fund, and the amount of the distribution is taxable income to you. Similarly, if the stocks owned by the mutual fund pay dividends, those will be passed on to you as a dividend distribution and all the above still applies.

Especially important, you cannot declare to the IRS that you have a loss and you cannot deduct the loss on your income tax returns that year.

You declare the $33 on your tax return that year and pay taxes on it. Two years later, you sell all 103 shares that you own for $10.50 per share. Your total investment was $1000 + $33 = $1033. You get $1081.50 from the fund, and you will owe taxes on $1081.50 - $1033 = $48.50. You have a profit of $50 on the 100 shares originally bought and a loss of $1.50 on the 3 shares bought for $11: the net result is a gain of $48.50. You do not pay taxes on $81.50 as the profit from your original $1000 investment; you pay taxes only on $48.50 (remember that you already paid taxes on the $33). The mutual fund will report on Form 1099-B that you sold 103 shares for $1081.50 and that you bought the 103 shares for an average price of $1033/103 = $10.029 per share.

If the net is a loss, you can deduct up to $3000 in a year, and carry the rest forward to later years to offset capital gains in later years.

When you own a stock and cannot find cost basis, there are times that you might realize the basis is so low that just entering zero will cost you less than $100 in extra tax. You are not truthful, of course, but this kind of false statement isn't going to lead to any issue. If it gets noticed within an audit, no agent is going to give it more than a moment of time and perhaps suggest, \"\"you didn't even know the year it was bought?\"\" but there would be no consequence. My answer is for personal returns, I'm sure for business, accuracy to the dollar is actually important.\"", "title": "" }, { "docid": "389654", "text": "I am also neither an attorney nor a tax advisor. Yes, the rent money you pay to your friend is taxable income, but suddenly all kinds of expenses around the house - including a fraction of the interest paid on the mortgage - become tax deductible. For example, let's say that the mortgage is $1000 / month and you pay your friend $500 / month. If you live in 50% of the house, then he can deduct 50% (plus or minus) of the expenses associated with owning the house, including: All of these things (50% of them, anyway) become tax deductible.

You cannot deduct amounts you pay for local benefits that tend to increase the value of your property. Local benefits include the construction of streets, sidewalks, or water and sewer systems. You must add these amounts to the basis of your property. You can, however, deduct assessments (or taxes) for local benefits if they are for maintenance, repair, or interest charges related to those benefits. An example is a charge to repair an existing sidewalk and any interest included in that charge. If only a part of the assessment is for maintenance, repair, or interest charges, you must be able to show the amount of that part to claim the deduction. If you cannot show what part of the assessment is for maintenance, repair, or interest charges, you cannot deduct any of it. An assessment for a local benefit may be listed as an item in your real estate tax bill. If so, use the rules in this section to find how much of it, if any, you can deduct. I have never seen a tax bill that said this amount is for new streets, and the rest i for things the IRS says you can deduct. The issue is that if the Center City tax bill is a separate line or a separate bill then does it count. I would go back to the first line of the quote from Pub 530: You cannot deduct amounts you pay for local benefits that tend to increase the value of your property. Then I would look at the quote from the CCD web site: The Center City District (CCD) is a business improvement district. Our mission is to keep Philadelphia's downtown, called Center City, clean, safe, beautiful and fun. We provide security, cleaning and promotional services that supplement, but do not replace, basic services provided by the City of Philadelphia and the fundamental responsibilities of property owners. CCD also makes physical improvements to the downtown, installing and maintaining lighting, > signs, banners, trees and landscape elements. and later on the same page: CCD directly bills and collects mandatory payments from properties in the district. CCD also receives voluntary contributions from the owners of tax-exempt properties that benefit from our services. The issues is that it is a business improvement district (BID), and you aren't a business: I did find this document from the city of Philadelphia explain how to establish a BID: If the nature of the BID is such that organizers wish to include residential properties within the district and make these properties subject to the assessment, it may make sense to assess these properties at a lower level than a commercial property, both because BID services and benefits are business-focused, and because owner-occupants often cannot treat NID assessments as tax-deductible business expenses, like commercial owners do. Care must be taken to ensure that the difference in commercial and residential assessment rates is equitable, and complies with the requirements of the CEIA. from the same document: Funds for BID programs and services are generated from a special assessment paid by the benefited property owners directly to the organization that manages the BID’s activities. (Note: many leases have a clause that allows property owners to pass the BID assessment on to their tenants.) Because they are authorized by the City of Philadelphia, the assessment levied by the BID becomes a legal obligation of the property owner and failure to pay can result in the filing of a lien. I have seen discussion that some BIDS can accept tax deductible donations. This means if a person itemizes they can deduct the donation. I would then feel comfortable deducting the tax because: If you can't deduct it that would mean the only people who can't deduct it are home owners. So deduct it.

Brian is not in The Beach Boys.
[ { "docid": "The_Beach_Boys", "text": "The Beach Boys are an American rock band formed in Hawthorne , California , in 1961 . The group 's original lineup consisted of brothers Brian , Dennis , and Carl Wilson ; their cousin Mike Love ; and their friend Al Jardine . Distinguished by their vocal harmonies and early surf songs , they are one of the most influential acts of the rock era . The group , led by their principal songwriter and producer Brian , pioneered novel approaches to popular music form and production , combining their affinities for jazz-based vocal groups , 1950s rock and roll , and black R&B to create their unique sound . He later arranged his compositions for studio orchestras and explored a variety of other styles , often incorporating classical or jazz elements and unconventional recording techniques in innovative ways . The Beach Boys began as a garage band managed by the Wilsons ' father Murry , with Brian 's increasingly sophisticated songwriting and recording abilities dominating their creative direction . Emerging at the vanguard of the `` California Sound '' , they performed original material that reflected a southern California youth culture of surfing , cars , and romance . After 1964 , they abandoned the surfing aesthetic for more personal lyrics and multi-layered sounds . In 1966 , the Pet Sounds album and `` Good Vibrations '' single vaulted the group to the top level of rock innovators and established the band as symbols of the nascent counterculture era . Following the dissolution of the group 's Smile project in 1967 , Brian gradually ceded production and songwriting duties to the rest of the band , reducing his input because of mental health and substance abuse issues . The group 's public image subsequently faltered , and despite efforts to continue their psychedelic/avant-garde ventures and reclaim their hippie audiences , they were dismissed as an embodiment of the values and outlooks shared by early 1960s white , suburban teenagers . The continued success of their greatest hits albums during the mid 1970s precipitated the band 's transition into an oldies act , a move that was denigrated by critics and many fans . Since the 1980s , much-publicized legal wrangling over royalties , songwriting credits and use of the band 's name transpired . Dennis drowned in 1983 and Carl died of lung cancer in 1998 . After Carl 's death , many live configurations of the band fronted by Mike Love and Bruce Johnston continued to tour into the 2000s while other members pursued solo projects . Even though Wilson and Jardine have not performed with Love and Johnston 's band since their one-off 2012 reunion tour , they remain a part of the Beach Boys ' corporation , Brother Records Inc. . The Beach Boys are one of the most critically acclaimed , commercially successful , and widely influential bands of all time . The group had over eighty songs chart worldwide , thirty-six of them US Top 40 hits ( the most by an American rock band ) , four reaching number-one on the Billboard Hot 100 chart . The Beach Boys have sold in excess of 100 million records worldwide , making them one of the world 's best-selling bands of all time and are listed at No. 12 on Rolling Stone magazine 's 2004 list of the `` 100 Greatest Artists of All Time '' . The core quintet of the three Wilsons , Love and Jardine were inducted into the Rock and Roll Hall of Fame in 1988 .", "title": "" } ]

A secondary objective was to examine the extent to which metabolic (body mass index, high-density lipoprotein and total cholesterol) and inflammatory (C-reactive protein) markers mediate the relationship between screen time and CVD events. BACKGROUND: Although some evidence suggests that prolonged sitting is linked to CVD risk factor development regardless of physical activity participation, studies with hard outcomes are scarce. METHODS: A population sample of 4,512 (1,945 men) Scottish Health Survey 2003 respondents (≥35 years) were followed up to 2007 for all-cause mortality and CVD events (fatal and nonfatal combined). Main exposures were interviewer-assessed screen time (<2 h/day; 2 to <4 h/day; and ≥4 h/day) and moderate to vigorous intensity physical activity. RESULTS: Two hundred fifteen CVD events and 325 any-cause deaths occurred during 19,364 follow-up person-years. The covariable (age, sex, ethnicity, obesity, smoking, social class, long-standing illness, marital status, diabetes, hypertension)-adjusted hazard ratio (HR) for all-cause mortality was 1.52 (95% confidence interval [CI]: 1.06 to 2.16) and for CVD events was 2.30 (95% CI: 1.33 to 3.96) for participants engaging in ≥4 h/day of screen time relative to <2 h/day. Adjusting for physical activity attenuated these associations only slightly (all-cause mortality: HR: 1.48, 95% CI: 1.04 to 2.13; CVD events: HR: 2.25, 95% CI: 1.30 to 3.89). Exclusion of participants with CVD events in the first 2 years of follow-up and previous cancer registrations did not change these results appreciably. Approximately 25% of the association between screen time and CVD events was explained collectively by C-reactive protein, body mass index, and high-density lipoprotein cholesterol. CONCLUSIONS: Recreational sitting, as reflected by television/screen viewing time, is related to raised mortality and CVD risk regardless of physical activity participation. Inflammatory and metabolic risk factors partly explain this relationship. Copyright © 2011 American College of Cardiology Foundation. Published by Elsevier Inc.

The aim of this study was to systematically review the evidence on associations between occupational sitting and health risks. EVIDENCE ACQUISITION: Studies were identified in March-April 2009 by literature searches in PubMed, PsycINFO, CENTRAL, CINAHL, EMBASE, and PEDro, with subsequent related-article searches in PubMed and citation searches in Web of Science. Identified studies were categorized by health outcome. Two independent reviewers assessed methodologic quality using a 15-item quality rating list (score range 0-15 points, higher score indicating better quality). Data on study design, study population, measures of occupational sitting, health risks, analyses, and results were extracted. EVIDENCE SYNTHESIS: 43 papers met the inclusion criteria (21% cross-sectional, 14% case-control, 65% prospective); they examined the associations between occupational sitting and BMI (n=12); cancer (n=17); cardiovascular disease (CVD, n=8); diabetes mellitus (DM, n=4); and mortality (n=6). The median study-quality score was 12 points. Half the cross-sectional studies showed a positive association between occupational sitting and BMI, but prospective studies failed to confirm a causal relationship. There was some case-control evidence for a positive association between occupational sitting and cancer; however, this was generally not supported by prospective studies. The majority of prospective studies found that occupational sitting was associated with a higher risk of DM and mortality. CONCLUSIONS: Limited evidence was found to support a positive relationship between occupational sitting and health risks.

Growth and apoptosis of tumor cells were measured. Serum samples were also used to measure insulin, IGF-1, IGFBP-1. RESULTS: The Diet and Exercise and the Exercise alone groups had lower serum insulin and IGF-1 but higher IGFBP-1 compared to Controls. LNCaP cell growth was reduced in both groups compared to Control and there was a major increase in apoptosis of tumor cells.

RECENT FINDINGS: Experimental studies have shown that short-term partial sleep restriction decreases glucose tolerance, increases sympathetic tone, elevates cortisol concentrations, decreases the satiety hormone leptin, increases the appetite-stimulating hormone ghrelin, and increases hunger and appetite. Short sleep duration might increase the risk of becoming obese, because it does not allow the recovery of a hormonal profile facilitating appetite control. Lack of sleep could also lead to weight gain and obesity by increasing the time available for eating and by making the maintenance of a healthy lifestyle more difficult. Furthermore, the increased fatigue and tiredness associated with sleeping too little could lessen one's resolve to follow exercise regimens. SUMMARY: Short sleep duration appears to be a novel and independent risk factor for obesity. With the growing prevalence of chronic sleep restriction, any causal association between reduced sleep and obesity would have substantial importance from a public health standpoint. Future research is needed to determine whether sleep extension in sleep-deprived obese individuals will influence appetite control and/or reduce the amount of body fat.", "title": "Do all sedentary activities lead to weight gain: sleep does not." }, { "docid": "MED-4787", "text": "Background Despite strong evidence of an inverse association of physical activity with postmenopausal breast cancer risk, whether a certain intensity or time of life of physical activity is most effective for lowering breast cancer risk is not known. Methods In 118,899 postmenopausal women in the prospective NIH-AARP Diet and Health Study, we examined the relations of light and moderate-to-vigorous intensity physical activity during four periods of life (\"historical\": ages 15-18, 19-29, 35-39 years; \"recent\": past 10 years) to postmenopausal breast cancer risk. Physical activity was assessed by self-report at baseline, and 4287 incident breast cancers were identified over 6.6 years of follow-up. Results In age-adjusted and multivariate Cox regression models, >7 hours/week of moderate-to-vigorous activity during the past 10 years was associated with 16% reduced risk of postmenopausal breast cancer (RR:0.84; 95%CI:0.76,0.93) compared with inactivity. The association remained statistically significant after adjustment for BMI (RR:0.87; 95%CI:0.78,0.96). Neither moderate-to-vigorous activity during other periods of life nor light intensity activity during any period of life was related to breast cancer risk, and associations did not vary by tumor characteristics. Conclusion A high level of recent, but not historical, physical activity of moderate-to-vigorous intensity is associated with reduced postmenopausal breast cancer risk.

There is a focus in many countries to reduce the level of human illness from food-borne pathogens. Reduction of the prevalence of contaminated poultry meat or eggs is one major area of focus. The other is risk communication to the consumer, where information aimed at changing the food preparation behaviour has been utilised as a risk management tool. The efficacy of messages such as 'cook poultry meat and eggs thoroughly' or 'wash your hands' will depend both on the ability to change consumer behaviour as well as where the risk can best be mitigated. In order to prioritise what message should be given to the consumer, the relative contribution of different exposure pathways finally leading to ingestion of the pathogens and resulting in illness needs to be known. It is important to know whether cross-contamination events or undercooking are the greatest risk lurking in consumers' kitchens. A review of studies looking at the location of pathogens in food products has been performed and data regarding internal and external (surface) contamination of poultry meat with Salmonella spp. and Campylobacter jejuni and C. coli is presented.

The objective of this study was to determine whether detection of childhood celiac disease by mass screening improves long-term health status and health-related quality of life. METHODS: We conducted a prospective 10-year follow-up study of 32 children who were aged 2 to 4 years, had celiac disease identified by mass screening, and had a gluten-free diet (19) or a normal gluten-containing diet (13). The follow-up included assessments of general health status, celiac disease-associated symptoms, celiac disease-associated serum antibodies, and health-related quality of life. RESULTS: Ten years after mass screening, 81% of the children were adhering to a gluten-free diet. The health status improved in 66% of the treated children: in 41% by early treatment and in 25% by prevention of the gluten-dependent symptoms that they developed after diagnosis. For 19% of the children, treatment after screening would not have improved their health status, because they had no symptoms at screening and have remained symptom-free while consuming gluten. The health-related quality of life of the children with symptoms improved significantly after 1 year of gluten-free diet. Ten years after screening, the health-related quality of life of the children with celiac disease was similar to that of the reference population. CONCLUSION: Identification by mass screening led 10 years later to health improvement in 66% of children without deterioration of generic health-related quality of life. There is a good compliance after mass screening. In a research setting, delaying treatment for children without symptoms seems to be an option after a positive screening test.

Manufacturers are not required to notify the FDA of a GRAS determination, although in some instances they notify the agency. The individuals that companies select to make these determinations may have financial conflicts of interest. OBJECTIVE: To determine the extent to which individuals selected by manufacturers to make GRAS determinations have conflicts of interest between their obligations to ensure that the use of the additive is safe and their financial relationships to the company. DESIGN Using conflict of interest criteria developed by a committee of the Institute of Medicine, we analyzed 451 GRAS notifications that were voluntarily submitted to the FDA between 1997 and 2012. MAIN OUTCOMES AND MEASURES: Number of GRAS notices submitted to the FDA; frequency of various types of relationships between decision maker and additive manufacturer; frequency of participation on GRAS panels by individuals; and number of GRAS safety determinations identified by the FDA that were not submitted to the agency. RESULTS: For the 451 GRAS notifications, 22.4% of the safety assessments were made by an employee of an additive manufacturer, 13.3% by an employee of a consulting firm selected by the manufacturer, and 64.3% by an expert panel selected by either a consulting firm or the manufacturer. A standing expert panel selected by a third party made none of these safety assessments. The 290 panels that made GRAS determinations had an average of 3.5 members, with a maximum of 7. Ten individuals served on 27 or more panels; 1 individual served on 128 panels (44.1%). At least 1 of the 10 individuals with the most frequent service was a member of 225 panels (77.6%). CONCLUSIONS AND RELEVANCE: Between 1997 and 2012, financial conflicts of interest were ubiquitous in determinations that an additive to food was GRAS. The lack of independent review in GRAS determinations raises concerns about the integrity of the process and whether it ensures the safety of the food supply, particularly in instances where the manufacturer does not notify the FDA of the determination.

It is increasingly believed that consumption of dietary cholesterol and egg yolks is harmless. There are good reasons for long-standing recommendations that dietary cholesterol should be limited to less than 200 mg/day; a single large egg yolk contains approximately 275 mg of cholesterol (more than a day’s worth of cholesterol). Although some studies showed no harm from consumption of eggs in healthy people, this outcome may have been due to lack of power to detect clinically relevant increases in a low-risk population. Moreover, the same studies showed that among participants who became diabetic during observation, consumption of one egg a day doubled their risk compared with less than one egg a week. Diet is not just about fasting cholesterol; it is mainly about the postprandial effects of cholesterol, saturated fats, oxidative stress and inflammation. A misplaced focus on fasting lipids obscures three key issues. Dietary cholesterol increases the susceptibility of low-density lipoprotein to oxidation, increases postprandial lipemia and potentiates the adverse effects of dietary saturated fat. Dietary cholesterol, including egg yolks, is harmful to the arteries. Patients at risk of cardiovascular disease should limit their intake of cholesterol. Stopping the consumption of egg yolks after a stroke or myocardial infarction would be like quitting smoking after a diagnosis of lung cancer: a necessary action, but late. The evidence presented in the current review suggests that the widespread perception among the public and health care professionals that dietary cholesterol is benign is misplaced, and that improved education is needed to correct this misconception. Résumé Une idée fausse et généralisée se répand au sein du public canadien et des médecins, qui pensent de plus en plus que la consommation de cholestérol alimentaire et de jaunes d’œuf est inoffensive. Les recommandations de longue date qui préconisent de limiter le cholestérol alimentaire à moins de 200 mg/jour reposent sur de bonnes raisons. Un seul gros jaune d’œuf contient environ 275 mg de cholestérol (plus que la portion quotidienne de cholestérol). Même si certaines études ont démontré que la consommation d’œufs n’est pas nuisible chez les personnes en santé, ce résultat peut découler de l’absence de capacité à déceler des augmentations pertinentes sur le plan clinique au sein d’une population à faible risque. De plus, les mêmes études ont révélé que chez les participants devenus diabétiques pendant la période d’observation, la consommation d’un œuf par jour doublait leur risque par rapport à la consommation de moins d’un œuf par semaine. Le régime ne vise pas à éviter le cholestérol, mais surtout les effets postprandiaux du cholestérol, des gras saturés, du stress oxydant et de l’inflammation. Le fait de se concentrer à tort sur les lipides à jeun occulte trois enjeux. Le cholestérol alimentaire accroît la susceptibilité des lipoprotéines à faible densité à l’oxydation, accroît la lipémie postprandiale et potentialise les effets secondaires des graisses saturées alimentaires. Le cholestérol alimentaire, y compris les jaunes d’œuf, est nuisible pour les artères. Les patients vulnérables aux maladies cardiovasculaires devraient limiter leur consommation de cholestérol. Le fait d’arrêter de consommer des jaunes d’œuf après un accident vasculaire cérébral ou un infarctus du myocarde s’apparenterait à arrêter de fumer après un diagnostic de cancer du poumon : c’est un geste nécessaire, mais entrepris tardivement.

We examined if adherence to ideal levels of the seven AHA cardiovascular health metrics was associated with incident cancers in the Atherosclerosis Risk In Communities (ARIC) study over 17-19 years of follow-up. Methods and Results After exclusions for missing data and prevalent cancer, 13,253 ARIC participants were included for analysis. Baseline measurements were used to classify participants according to seven AHA cardiovascular health metrics. Combined cancer incidence (excluding non-melanoma skin cancers) from 1987-2006 was captured using cancer registries and hospital surveillance; 2880 incident cancer cases occurred over follow-up. Cox regression was used to calculate hazard ratios for incident cancer. There was a significant (p-trend< .0001), graded, inverse association between the number of ideal cardiovascular health metrics at baseline and cancer incidence. Participants meeting goals for 6-7 ideal health metrics (2.7% of the population) had 51% lower risk of incident cancer than those meeting goals for 0 ideal health metrics. When smoking was removed from the sum of ideal health metrics, the association was attenuated with participants meeting goals for 5-6 health metrics having 25% lower cancer risk than those meeting goals for 0 ideal health metrics (p-trend = .03).

However, the association between nut consumption and mortality remains unclear. METHODS We examined the association between nut consumption and subsequent total and cause-specific mortality among 76,464 women in the Nurses’ Health Study (1980–2010) and 42,498 men in the Health Professionals Follow-up Study (1986–2010). Participants with a history of cancer, heart disease, or stroke were excluded. Nut consumption was assessed at baseline and updated every 2 to 4 years. RESULTS During 3,038,853 person-years of follow-up, 16,200 women and 11,229 men died. Nut consumption was inversely associated with total mortality among both women and men, after adjustment for other known or suspected risk factors. The pooled multivariate hazard ratios for death among participants who ate nuts, as compared with those who did not, were 0.93 (95% confidence interval [CI], 0.90 to 0.96) for the consumption of nuts less than once per week, 0.89 (95% CI, 0.86 to 0.93) for once per week, 0.87 (95% CI, 0.83 to 0.90) for two to four times per week, 0.85 (95% CI, 0.79 to 0.91) for five or six times per week, and 0.80 (95% CI, 0.73 to 0.86) for seven or more times per week (P<0.001 for trend).

We conducted a retrospective chart review of patients who came to a family practice office seeking nutritional counseling for weight loss. All of these patients were prescribed an HND diet in an extended counseling session with a family physician. METHODS: A convenience sample (N = 56) of all patients seeking dietary counseling for weight loss from a family practice physician in a 3-year period was included in the chart review. No personal identifying data were recorded. The initial counseling sessions averaged 1 hour in length. Patients were provided with a sample HND daily meal plan and recipes and with verbal and written information about the rationale for the diet. Data recorded from patients' charts at 6-month intervals for up to 2 years of follow-up (when available) included weight, blood pressure, total cholesterol, high-density lipoprotein (HDL) cholesterol, low-density lipoprotein (LDL) cholesterol, triglycerides, and cholesterol:HDL ratio. Non-parametric statistical testing using the Friedman rank order (exact) test for k-related samples was conducted. A follow-up survey on adherence and medication use was completed by 38 patients. RESULTS: Of the 33 patients who returned for follow-up after 1 year, the mean weight loss was 31 lbs (P = .000). Of the 19 patients who returned after 2 years, the mean weight loss was 53 lbs (P = .000), mean cholesterol fell by 13 points, LDL by 15 points, triglycerides by 17 points, and cardiac risk ratio dropped from 4.5 to 3.8. Changes in systolic and diastolic blood pressure were highly significant at all follow-up time intervals (P < or = .001).

CONCLUSIONS: Weight loss was sustained in patients who returned for follow-up and was more substantial in those who reported good adherence to the recommendations. However, many patients were lost to follow-up. Favorable changes in lipid profile and blood pressure were noted. An HND diet has the potential to provide sustainable, significant, long-term weight loss and may provide substantial lowering of cardiac risk in patients who are motivated and provided with extended one-on-one counseling and follow-up visits.

Measurement Investigator documented 12,555 deaths (2,458 cardiovascular, 5,780 cancer) in women and 8,678 deaths (2,746 cardiovascular, 2,960 cancer) in men. Results The overall low-carbohydrate score was associated with a modest increase in overall mortality in pooled analysis (Hazard Ratio, HR, comparing extreme deciles=1.12 (95% CI=1.01-1.24, p-trend=0.14). The animal low-carbohydrate score was associated with a higher all-cause mortality (pooled HR comparing extreme deciles=1.23, 95% CI=1.11-1.37, p-trend=0.05), cardiovascular mortality (corresponding HR=1.14, 95% CI=1.01-1.29, p-trend=0.029), and cancer mortality (corresponding HR=1.28, 95% CI 1.02-1.60, p for trend = 0.09). In contrast, a higher vegetable low-carbohydrate score was associated with lower all-cause (HR=0.80, 95% CI=0.75-0.85, p-trend<0.001) and cardiovascular mortality (HR=0.77, 95% CI=0.68-0.87, p-trend<0.001). Limitations Diet and lifestyle characteristics were assessed with some degree of error, however, sensitivity analyses indicated that results were not unlikely to be substantially affected by residual or confounding or an unmeasured confounder. In addition, participants were not a representative sample of the U.S. population. Conclusion A low-carbohydrate diet based on animal sources was associated with higher all-cause mortality in both men and women, whereas a vegetable-based low-carbohydrate diet was associated with lower all-cause and cardiovascular disease mortality rates.

In this paper we review literature relating to mental health outcomes across the lifespan. Studies conducted in the preschool years, school age and adolescence, and adulthood show continuity in outcomes and point to an increased risk for inattention, socio-communicative problems and emotional difficulties in individuals born extremely preterm. Both behavioural and neuroimaging studies also provide evidence of a neurodevelopmental origin for mental health disorders in this population. Here we summarise contemporary evidence and highlight key methodological considerations for carrying out and interpreting studies in this field. Copyright © 2013 Elsevier Ltd.

We present a conceptual framework to assess the economics of elimination and analyse a central component of that framework-potential short-term to medium-term financial savings. After a review that showed a dearth of existing evidence, the net present value of elimination in five sites was calculated and compared with effective control. The probability that elimination would be cost-saving over 50 years ranged from 0% to 42%, with only one site achieving cost-savings in the base case. These findings show that financial savings should not be a primary rationale for elimination, but that elimination might still be a worthy investment if total benefits are sufficient to outweigh marginal costs. Robust research into these elimination benefits is urgently needed.", "title": "Costs and financial feasibility of malaria elimination" } ]

The decrease has been so emphatic that South Africa now meets the World Health Organization (WHO) threshold for malaria elimination. Given the Millennium Development Goal of reversing the spread of malaria by 2015, South Africa is being urged to adopt an elimination agenda. This study aimed to determine the appropriateness of implementing a malaria elimination programme in present day South Africa. METHODS An assessment of the progress made by South Africa in terms of implementing an integrated malaria control programme across the three malaria-endemic provinces was undertaken. Vector control and case management data were analysed from the period of 2000 until 2011. RESULTS Both malaria-related morbidity and mortality have decreased significantly across all three malaria-endemic provinces since 2000. The greatest decline was seen in KwaZulu-Natal where cases decreased from 42,276 in 2000 to 380 in 2010 and deaths dropped from 122 in 2000 to six in 2010. Although there has been a 49.2 % (8,553 vs 4,214) decrease in the malaria cases reported in Limpopo Province, currently it is the largest contributor to the malaria incidence in South Africa. Despite all three provinces reporting average insecticide spray coverage of over 80%, malaria incidence in both Mpumalanga and Limpopo remains above the elimination threshold. Locally transmitted case numbers have declined in all three malaria provinces but imported case numbers have been increasing. Knowledge gaps in vector distribution, insecticide resistance status and drug usage were also identified. CONCLUSIONS Malaria elimination in South Africa is a realistic possibility if certain criteria are met. Firstly, there must be continued support for the existing malaria control programmes to ensure the gains made are sustained. Secondly, cross border malaria control initiatives with neighbouring countries must be strongly encouraged and supported to reduce malaria in the region and the importation of malaria into South Africa. Thirdly, operational research, particularly on vector distribution and insecticide resistance status must be conducted as a matter of urgency, and finally, the surveillance systems must be refined to ensure the information required to inform an elimination agenda are routinely collected.", "title": "The feasibility of malaria elimination in South Africa" }, { "docid": "27580223", "text": "The Islamic Republic of Iran is in the pre-elimination phase of malaria control, but malaria epidemics are still a concern in the south of the country.

A zero-truncated negative binomial model was used to investigate the relation between predictor variables and the total number of malaria cases. Malaria epidemics occurred mainly in the southern part of the province, mostly between July and October, peaking in August.

METHODS In this descriptive study, data were analyzed by applications of different variables at district level. All districts in the three south eastern provinces, in which malaria has local transmission, were considered. Malaria cases has been determined and studied based on the national malaria surveillance system. RESULTS Since vivax malaria is predominant in Sistan & Baluchestan Province, number of vivax cases is equal to malaria positive cases approximately. The important point is that Nikshahr contains the maximum number of local vivax cases in this province and the maximum number of falciparum cases is reported from Sarbaz district. Among all districts of Hormozgan Province, no case of autochthonous falciparum was detected except in Bandar Jask and one case in Minab. There was no case of autochthonous falciparum in Kerman Province, except in Kahnoj and Ghale Ganj that each of them had one case in 2007.

On a much shorter time scale, the last half century has seen in microcosm a history of large fluctuations in endemicity and impact of malaria across the spectrum of rice fields and rain forests, mountains and plains that reflect the vast ecological diversity inhabited by this majority aggregation of mankind. That period has seen some of the most dramatic changes in social and economic structure, in population size, density and mobility, and in political structure in history: all have played a part in the changing face of malaria in this extensive region of the world. While the majority of global malaria cases currently reside in Africa, greater numbers inhabited Asia earlier this century before malaria programs savored significant success, and now Asia harbors a global threat in the form of the epicenter of multidrug resistant Plasmodium falciparum which is gradually encompassing the tropical world. The latter reflects directly the vicissitudes of economic change over recent decades, particularly the mobility of populations in search of commerce, trade and personal fortunes, or caught in the misfortunes of physical conflicts. The period from the 1950s to the 1990s has witnessed near \"eradication\" followed by resurgence of malaria in Sri Lanka, control and resurgence in India, the influence of war and postwar instability on drug resistance in Cambodia, increase in severe and cerebral malaria in Myanmar during prolonged political turmoil, the essential disappearance of the disease from all but forested border areas of Thailand where it remains for the moment intractable, the basic elimination of vivax malaria from many provinces of central China. Both positive and negative experiences have lessons to teach in the debate between eradication and control as alternative strategies. China has for years held high the goal of \"basic elimination\", eradication by another name, in sensible semi-defiance of WHO dictates. The Chinese experience makes it clear that, given community organization, exhaustive attention to case detection, management and focus elimination, plus the political will at all levels of society, it is possible both to eliminate malaria from large areas of an expansive nation and to implement surveillance necessary to maintain something approaching eradication status in those areas. But China has not succeeded in the international border regions of the tropical south where unfettered population movement confounds the program. Thailand, Malaysia and to an extent Vietnam have also reached essential elimination in their rice field plains by vigorous vertical programs but fall short at their forested borders. Economics is central to the history of the rise and fall of nations, and to the history of disease in the people who constitute nations. The current love affair with free market economics as the main driving force for advance of national wealth puts severe limitations on the essential involvement of communities in malaria management. The task of malaria control or elimination needs to be clearly related to the basic macroeconomic process that preoccupies governments, not cloistered away in the health sector Historically malaria has had a severe, measurable, negative impact on the productivity of nations. Economic models need rehoning with political aplomb and integrating with technical and demographic strategies.

To advance the contemporary debate about these issues, this paper presents a historical review of commonly used terms, including control, elimination, and eradication, to help contextualize current understanding of these concepts. The review has been supported by analysis of the underlying mathematical concepts on which these definitions are based through simple branching process models that describe the proliferation of malaria cases following importation. Through this analysis, the importance of pragmatic definitions that are useful for providing malaria control and elimination programmes with a practical set of strategic milestones is emphasized, and it is argued that current conceptions of elimination in particular fail to achieve these requirements. To provide all countries with precise targets, new conceptual definitions are suggested to more precisely describe the old goals of \"control\" - here more exactly named \"controlled low-endemic malaria\" - and \"elimination. \" Additionally, it is argued that a third state, called \"controlled non-endemic malaria,\" is required to describe the epidemiological condition in which endemic transmission has been interrupted, but malaria resulting from onwards transmission from imported infections continues to occur at a sufficiently high level that elimination has not been achieved.

An evaluation of historical and current definitions of malaria elimination" }, { "docid": "37248570", "text": "After a lapse of almost 40 years, malaria eradication is back on the global health agenda. Inspired by the Gates Malaria Forum in October 2007,1,2 key organizations are starting to debate the pros and cons of redefining eradication as an explicit goal of malaria control efforts. Attempts to eliminate malaria in southern Africa3 and Pacific Island states,4 and WHO’s Global Malaria Programme agenda and field manual for malaria elimination,5,6 foreshadow this movement towards another global attempt at eradication. When marking 60 years of WHO’s commitment to fighting malaria, we must ask what has been achieved, but also what can we learn from the past. We now know so much more about the biology of parasite-host responses, the determinants of endemicity and transmission dynamics, the social, economic and cultural implications of malaria at household, community and national levels, and the demands made upon health systems in endemic countries. We do not yet know how to synthesize and integrate this knowledge to achieve elimination in different settings. Regional malaria elimination campaigns were first conducted in the late 1940s, preparing the ground for the Global Malaria Eradication Program in 1955. This campaign succeeded in eliminating malaria from Europe, North America, the Caribbean and parts of Asia and South-Central America.7 But no major success occurred in sub-Saharan Africa, which accounts for 80% of today’s burden of malaria.8 When the aspiration of global eradication was abandoned in 1969, the main reasons for failure were technical challenges of executing the strategy especially in Africa. The post-eradication era from 1969 to 1991 focused on technical issues, and research and development for new tools, leading to advances in drug and vaccine development, vector control and insecticide-treated nets. These decades also brought a better understanding of the social, economic and cultural dimensions of malaria. There was little global support provided specifically for malaria control in the newly independent states of Africa that were struggling to establish broad-based health systems and primary health care. By 1992, the combination of a worsening malaria situation and promising technical developments led to renewed global focus on malaria control. The Roll Back Malaria initiative, launched by WHO in 1998, led to the Abuja Declaration in 2000, which defined progressive intervention coverage targets for control designed to eliminate malaria as a public health problem, while emphasizing that this could only be achieved through vastly strengthened local health systems.9 Increased resources through the Global Fund to Fight AIDS, Tuberculosis and Malaria, the World Bank’s Booster Program, the US President’s Malaria Initiative and many others has meant that this page is finally beginning to turn as intervention coverage is rising.10 It is against this background that we hear this call for elimination/eradication. The challenges remain formidable. We all know that elimination in Africa is not possible with current tools. But efforts must focus beyond simply developing better tools, to include how existing and future tools can be strategically combined for maximum synergistic effectiveness when integrated into different health and social systems prevailing in endemic areas. Aiming at elimination and eradication further implies the need for effective surveillance strategies to monitor progress (again a challenge for health systems). This in turn requires a better understanding of malaria transmission heterogeneity in a globalized world with rapidly changing dynamics in environment, climate, migration and transnational cooperation. Maintaining long-term momentum in the face of success in regional elimination while waiting to achieve final eradication will be a major challenge. Shrinking the map by starting on the malaria margins with the “easy-to-eliminate” settings will boost morale initially but may bring marginal benefits to such areas at the expense of those where the burden of malaria is highest. Any strategic plan – and here we learn again from the past – needs to be a synchronous global effort, locally adapted in all endemic areas. Although we lack sufficient knowledge, systems and tools to eradicate malaria today, we do have a window of political will and financial resources to refocus on the goal of effective control through universal coverage of appropriate interventions. The prerequisites for a successful start are: (i) a process of inclusive discourse to agree on global vision, goals and strategy; and (ii) a global plan for all endemic areas describing how, where and when we move from control towards elimination. What must distinguish the new era, especially in Africa, is a real rather than rhetorical emphasis on health systems. ■", "title": "Malaria eradication back on the table." }, { "docid": "3929361", "text": "BACKGROUND Malaria elimination requires a variety of approaches individually optimized for different transmission settings. A recent field study in an area of low seasonal transmission in South West Cambodia demonstrated dramatic reductions in malaria parasite prevalence following both mass drug administration (MDA) and high treatment coverage of symptomatic patients with artemisinin-piperaquine plus primaquine. This study employed multiple combined strategies and it was unclear what contribution each made to the reductions in malaria. METHOD AND FINDINGS A mathematical model fitted to the trial results was used to assess the effects of the various components of these interventions, design optimal elimination strategies, and explore their interactions with artemisinin resistance, which has recently been discovered in Western Cambodia. The modelling indicated that most of the initial reduction of P. falciparum malaria resulted from MDA with artemisinin-piperaquine. The subsequent continued decline and near elimination resulted mainly from high coverage with artemisinin-piperaquine treatment. Both these strategies were more effective with the addition of primaquine. MDA with artemisinin combination therapy (ACT) increased the proportion of artemisinin resistant infections, although much less than treatment of symptomatic cases with ACT, and this increase was slowed by adding primaquine. Artemisinin resistance reduced the effectiveness of interventions using ACT when the prevalence of resistance was very high. The main results were robust to assumptions about primaquine action, and immunity. CONCLUSIONS The key messages of these modelling results for policy makers were: high coverage with ACT treatment can produce a long-term reduction in malaria whereas the impact of MDA is generally only short-term; primaquine enhances the effect of ACT in eliminating malaria and reduces the increase in proportion of artemisinin resistant infections; parasite prevalence is a better surveillance measure for elimination programmes than numbers of symptomatic cases; combinations of interventions are most effective and sustained efforts are crucial for successful elimination.", "title": "Optimising Strategies for Plasmodium falciparum Malaria Elimination in Cambodia: Primaquine, Mass Drug Administration and Artemisinin Resistance" }, { "docid": "15237660", "text": "BACKGROUND Long-lasting insecticide treated nets (LLINs) and indoor residual house spraying (IRS) are the main interventions for the control of malaria vectors in Zanzibar. The aim of the present study was to assess the susceptibility status of malaria vectors against the insecticides used for LLINs and IRS and to determine the durability and efficacy of LLINs on the island. METHODS Mosquitoes were sampled from Pemba and Unguja islands in 2010-2011 for use in WHO susceptibility tests. One hundred and fifty LLINs were collected from households on Unguja, their physical state was recorded and then tested for efficacy as well as total insecticide content. RESULTS Species identification revealed that over 90% of the Anopheles gambiae complex was An. arabiensis with a small number of An. gambiae s.s. and An. merus being present. Susceptibility tests showed that An. arabiensis on Pemba was resistant to the pyrethroids used for LLINs and IRS. Mosquitoes from Unguja Island, however, were fully susceptible to all pyrethroids tested. A physical examination of 150 LLINs showed that two thirds were damaged after only three years in use. All used nets had a significantly lower (p < 0.001) mean permethrin concentration of 791.6 mg/m2 compared with 944.2 mg/m2 for new ones. Their efficacy decreased significantly against both susceptible An. gambiae s.s. colony mosquitoes and wild-type mosquitoes from Pemba after just six washes (p < 0.001). CONCLUSION The sustainability of the gains achieved in malaria control in Zanzibar is seriously threatened by the resistance of malaria vectors to pyrethroids and the short-lived efficacy of LLINs.

A hundred years later research and understanding has made immense progress but the world still bears a huge burden of malaria. For the next century research requires both more specialism and a holistic range if it is to be used in control, requiring multidisciplinary team work. Environmental changes and interventions produce a dynamic and changing pattern of malaria, not the static one of the past. From the original parasite life cycle, research has analysed a series of other cycles at electron microscope, biochemical and genome levels on decreasing size scales and quantitative epidemiological cycles for control. Recent additions to these concepts have been stage-specific antigens, cycles of disease rather than parasites alone, considering populations of parasites rather than just cases, and also genetic variation in each component of the parasite-human host-vector triad. In this volume there emerges for the first time a coherent overall picture of the biomedical aspects of basic malariology as the interacting population genetics of malaria parasites, anophelines and people. This provides a coherent model for the new century dealing with the great biological malaria problems of drug resistance, vaccine development, insecticidal and net control and can feed, with socio-economic work, into the gathering renewal of control efforts. New work on large-scale changes of malaria in space and time enables us to be precise about effects of local and global environmental changes to predict epidemics. Future research will be as much about linking these different scales of understanding as control will be about linking different levels of the health system.

However, it remains unclear what overall reduction in transmission is achievable using currently available tools. METHODS AND FINDINGS We developed an individual-based simulation model for Plasmodium falciparum transmission in an African context incorporating the three major vector species (Anopheles gambiae s.s., An. arabiensis, and An. funestus) with parameters obtained by fitting to parasite prevalence data from 34 transmission settings across Africa. We incorporated the effect of the switch to artemisinin-combination therapy (ACT) and increasing coverage of long-lasting insecticide treated nets (LLINs) from the year 2000 onwards. We then explored the impact on transmission of continued roll-out of LLINs, additional rounds of indoor residual spraying (IRS), mass screening and treatment (MSAT), and a future RTS,S/AS01 vaccine in six representative settings with varying transmission intensity (as summarized by the annual entomological inoculation rate, EIR: 1 setting with low, 3 with moderate, and 2 with high EIRs), vector-species combinations, and patterns of seasonality. In all settings we considered a realistic target of 80% coverage of interventions. In the low-transmission setting (EIR approximately 3 ibppy [infectious bites per person per year]), LLINs have the potential to reduce malaria transmission to low levels (<1% parasite prevalence in all age-groups) provided usage levels are high and sustained. In two of the moderate-transmission settings (EIR approximately 43 and 81 ibppy), additional rounds of IRS with DDT coupled with MSAT could drive parasite prevalence below a 1% threshold. However, in the third (EIR = 46) with An. arabiensis prevailing, these interventions are insufficient to reach this threshold. In both high-transmission settings (EIR approximately 586 and 675 ibppy), either unrealistically high coverage levels (>90%) or novel tools and/or substantial social improvements will be required, although considerable reductions in prevalence can be achieved with existing tools and realistic coverage levels. CONCLUSIONS Interventions using current tools can result in major reductions in P. falciparum malaria transmission and the associated disease burden in Africa. Reduction to the 1% parasite prevalence threshold is possible in low- to moderate-transmission settings when vectors are primarily endophilic (indoor-resting), provided a comprehensive and sustained intervention program is achieved through roll-out of interventions. In high-transmission settings and those in which vectors are mainly exophilic (outdoor-resting), additional new tools that target exophagic (outdoor-biting), exophilic, and partly zoophagic mosquitoes will be required.", "title": "Reducing Plasmodium falciparum Malaria Transmission in Africa: A Model-Based Evaluation of Intervention Strategies" }, { "docid": "24916604", "text": "BACKGROUND The use of bisphosphonates for the prevention of skeletal related events in women with bone metastases from breast cancer is well established.

METHODS Charts and electronic files of patients who had received either clodronate or pamidronate at any time between January 2000 and December 2001 at three Canadian cancer centres were retrospectively reviewed. RESULTS There has been a marked improvement in the time between the diagnosis of bone metastases and the commencement of bisphosphonates from a median of 155 days in 1998 to 24 days in 2001.

Funding agencies develop policies based on these treatment guidelines, but often funding is more restrictive than the treatment guideline would suggest.

Individuals homozygous for alpha(+)-thalassaemia have microcytosis and an increased erythrocyte count. Alpha(+)-thalassaemia homozygosity confers considerable protection against severe malaria, including severe malarial anaemia (SMA) (Hb concentration < 50 g/l), but does not influence parasite count. We tested the hypothesis that the erythrocyte indices associated with alpha(+)-thalassaemia homozygosity provide a haematological benefit during acute malaria. METHODS AND FINDINGS Data from children living on the north coast of Papua New Guinea who had participated in a case-control study of the protection afforded by alpha(+)-thalassaemia against severe malaria were reanalysed to assess the genotype-specific reduction in erythrocyte count and Hb levels associated with acute malarial disease. We observed a reduction in median erythrocyte count of approximately 1.5 x 10(12)/l in all children with acute falciparum malaria relative to values in community children (p < 0.001). We developed a simple mathematical model of the linear relationship between Hb concentration and erythrocyte count. This model predicted that children homozygous for alpha(+)-thalassaemia lose less Hb than children of normal genotype for a reduction in erythrocyte count of >1.1 x 10(12)/l as a result of the reduced mean cell Hb in homozygous alpha(+)-thalassaemia. In addition, children homozygous for alpha(+)-thalassaemia require a 10% greater reduction in erythrocyte count than children of normal genotype (p = 0.02) for Hb concentration to fall to 50 g/l, the cutoff for SMA. We estimated that the haematological profile in children homozygous for alpha(+)-thalassaemia reduces the risk of SMA during acute malaria compared to children of normal genotype (relative risk 0.52; 95% confidence interval [CI] 0.24-1.12, p = 0.09). CONCLUSIONS The increased erythrocyte count and microcytosis in children homozygous for alpha(+)-thalassaemia may contribute substantially to their protection against SMA. A lower concentration of Hb per erythrocyte and a larger population of erythrocytes may be a biologically advantageous strategy against the significant reduction in erythrocyte count that occurs during acute infection with the malaria parasite Plasmodium falciparum.

SETTING England and Wales during 1970-84, and whole of the United Kingdom during 1985-96. SUBJECTS All 662 patients identified as sporadic cases of Creutzfeldt-Jakob disease. MAIN OUTCOME MEASURES Age distribution of patients, age specific time trends of disease, occupational exposure to cattle, potential exposure to causative agent of bovine spongiform encephalopathy. RESULTS During 1970-96 there was an increase in the number of sporadic cases of Creutzfeldt-Jakob disease recorded yearly in England and Wales. The greatest increase was among people aged over 70. There was a statistically significant excess of cases among dairy farm workers and their spouses and among people at increased risk of contact with live cattle infected with bovine spongiform encephalopathy. During 1994-6 there were six deaths from sporadic Creutzfeldt-Jakob disease in the United Kingdom in patients aged under 30.

The risk of exposure to blood transfusion occurring more than 10 years before disease onset and for some possible confounding factors was evaluated by calculating crude odds ratios (ORs).

METHODS In the period May 2003-January 2005 we reviewed all cases of paediatric malaria in the Netherlands notified by the Dutch Paediatric Surveillance System (Nederland Signalerings Centrum Kindergeneeskunde, NSCK) and the literature on imported malaria in children in Europe published between 1996 and 2006. RESULTS Malaria occurred mainly in children of long-term (n = 15, 47%) and new (n = 8, 25%) immigrants and was mostly acquired in sub-Saharan Africa. The dominant species was P. falciparum. Only one quarter of children had used adequate malaria chemoprophylaxis. Complicated disease occurred in 10 (31%) of cases. We also reviewed the literature and found 6082 reported cases of imported malaria among children in Europe; among these, four died and only one was reported to develop neurological sequelae.

To provide an update of this situation, we purchased 153 artemisinin-containing antimalarials, as convenience samples, in private drug stores from different regions of Myanmar. The quality of these drugs in terms of their artemisinin derivative content was tested using specific dipsticks for these artemisinin derivatives, as point-of-care devices.

With the increased interest in malaria elimination, understanding the impact on transmission of ACT and other antimalarial drugs with different pharmacodynamics becomes a key issue. This study estimates the reduction in transmission that may be achieved by introducing different types of treatment for symptomatic P. falciparum malaria in endemic areas. METHODS AND FINDINGS We developed a mathematical model to predict the potential impact on transmission outcomes of introducing ACT as first-line treatment for uncomplicated malaria in six areas of varying transmission intensity in Tanzania. We also estimated the impact that could be achieved by antimalarials with different efficacy, prophylactic time, and gametocytocidal effects. Rates of treatment, asymptomatic infection, and symptomatic infection in the six study areas were estimated using the model together with data from a cross-sectional survey of 5,667 individuals conducted prior to policy change from sulfadoxine-pyrimethamine to ACT. The effects of ACT and other drug types on gametocytaemia and infectiousness to mosquitoes were independently estimated from clinical trial data. Predicted percentage reductions in prevalence of infection and incidence of clinical episodes achieved by ACT were highest in the areas with low initial transmission. A 53% reduction in prevalence of infection was seen if 100% of current treatment was switched to ACT in the area where baseline slide-prevalence of parasitaemia was lowest (3.7%), compared to an 11% reduction in the highest-transmission setting (baseline slide prevalence = 57.1%). Estimated percentage reductions in incidence of clinical episodes were similar. The absolute size of the public health impact, however, was greater in the highest-transmission area, with 54 clinical episodes per 100 persons per year averted compared to five per 100 persons per year in the lowest-transmission area. High coverage was important. Reducing presumptive treatment through improved diagnosis substantially reduced the number of treatment courses required per clinical episode averted in the lower-transmission settings although there was some loss of overall impact on transmission. An efficacious antimalarial regimen with no specific gametocytocidal properties but a long prophylactic time was estimated to be more effective at reducing transmission than a short-acting ACT in the highest-transmission setting. CONCLUSIONS Our results suggest that ACTs have the potential for transmission reductions approaching those achieved by insecticide-treated nets in lower-transmission settings. ACT partner drugs and nonartemisinin regimens with longer prophylactic times could result in a larger impact in higher-transmission settings, although their long term benefit must be evaluated in relation to the risk of development of parasite resistance.", "title": "Modelling the Impact of Artemisinin Combination Therapy and Long-Acting Treatments on Malaria Transmission Intensity" }, { "docid": "27768226", "text": "PLoS Biology publishes today a research article by Gunther Eysenbach that is not about biology. It is about citations. It provides robust evidence that open-access articles (OA articles) are more immediately recognized and cited than non-OA articles. As such, it adds objective support to the belief we have always held that open-access publication speeds up scientific dialog between researchers and, consequently, should be extended to the whole scientific literature as quickly as possible. It is therefore fitting that we publish such a paper. We have long argued that papers freely available in a journal will be more often read and cited than those behind a subscription barrier. However, solid evidence to support or refute such a claim has been surprisingly hard to find. Since most open-access journals are new, comparisons of the effects of open access with established subscription-based journals are easily confounded by age and reputation. In the current study, Eysenbach compared citations compiled by Thomson Scientific (formerly Thomson ISI) to individual articles published between June 2004 and December 2004 in the same journal—namely, Proceedings of the National Academy of Sciences (PNAS), which announced its open-access option for authors on June 8 of that year, with an associated publication charge of US$1,000. Non-OA articles in PNAS are subject to a six-month “toll-access” delay before the article becomes publicly available. The results of this natural experiment are clear: in the 4 to 16 months following publication, OA articles gained a significant citation advantage over non-OA articles during the same period. They are twice as likely to be cited 4 to 10 months after publication and almost three times as likely between 10 and 16 months. Given that PNAS delays open access for only six months, the disparity between OA and non-OA articles in journals where the delay is longer or where articles remain “toll-access” is likely to be even greater. Eysenbach also looked at the impact of self-archiving non-OA articles. One route to open access, it is argued, is for authors to archive their published articles on their own Web sites or in institutional repositories, although this does not include an explicit business model to cover the cost of peer-review and publishing. The analysis revealed that self-archived articles are also cited less often than OA articles from the same journal. Yes, you're right; we do have a strong and vested interest in publishing results that so obviously endorse our existence. Moreover, the author of the article is also an editor of an open-access journal. But sometimes a potential conflict of interest can actually help to ensure rigor. In this case, we have an acute interest in ensuring that the article meets the same, if not higher, standards as any other research article we publish. Not only must the conclusions provide a significant advance for the field, but the study must be technically sound, with appropriate evidence to support those conclusions. As with all our research articles, we consulted throughout the evaluation process with an academic editor with appropriate expertise—in this case, Carol Tenopir, professor of information sciences at the University of Tennessee (Knoxville, Tennessee, United States). The article was reviewed by two experts in bibliometric analyses and information science, and an experienced research biologist with expertise in statistics. They all enthusiastically supported publication, although one understandably questioned the suitability of PLoS Biology as the publication venue. We have no intention of making PLoS Biology a regular home for bibliometric studies (even when about open access). What makes this study worth publishing in PLoS Biology is not only the relative strength of evidence supporting the claim but also the extent to which many (especially other publishers) have anticipated such an analysis. As far as we are aware, no other study has compared OA and non-OA articles from the same journal and controlled for so many potentially confounding factors. Eysenbach's multivariate analysis took into account the number of days since publication, number of authors, article type, country of the corresponding author, funding type, subject area, submission track ( PNAS has three different ways that authors can submit a paper), and the previous citation record of the first and last authors. He even administered a supplementary questionnaire to assess whether authors choosing the OA option in PNAS chose to do so for only their most important research (they didn't). As Ian Rowlands from the Centre for Publishing at University College London—and one of the reviewers who agreed to be identified in this article—said at the start of his review: “Many (most) of the papers and presentations I have read/seen on this topic have completely failed to address the kinds of confounding issues that are so convincingly tackled here. For that reason alone, this paper deserves to be published and alerted to the widest possible audience. ” In addition to providing evidence for the immediate advantage of open access, Eysenbach's analysis also highlights several potential challenges to its long-term future. Although a limited dataset, the citation history of the first and last authors differed between those who chose the open-access option and those who did not. In the group that chose open access, last authors tended to have a “stronger” previous citation record, whereas this situation was reversed among the group that declined the open-access option—here, it was the first authors who tended to be stronger. This may reflect varying attitudes of authors at different stages of their career, a stronger influence from the leader of a particular group, or an age- or career-related difference in the ability to pay the publication charge (e.g., [ 1]). Indeed, access to appropriate funds may also be a reason why a lower proportion of authors from European countries tended to choose the open-access option. In many of these countries, funds for page charges—and, by extension, open-access publication fees—are often not included within research grants. PNAS was one of the first journals to offer an open-access option to its authors. However, such hybrid journals are increasing: Blackwell, Springer, and Oxford University Press now provide this option as well. This means that similar experiments can be replicated. Moreover, although the evidence from the current analysis argues most strongly for a time advantage in citation for OA articles, a study over longer periods will reveal whether this translates into a sustained increase in the number of citations. In the meantime, open-access advocates should be emboldened by tangible evidence for what has seemed obvious all along.", "title": "Open Access Increases Citation Rate" }, { "docid": "6503185", "text": "Plasmodium falciparum malaria, an infectious disease caused by a parasitic protozoan, claims the lives of nearly a million children each year in Africa alone and is a top public health concern.

Renewed initiatives to eliminate malaria will benefit from an expanded repertoire of antimalarials, including new drugs that kill circulating P. falciparum gametocytes, thereby preventing transmission. Our current understanding of the biology of asexual blood-stage parasites and gametocytes and the ability to culture them in vitro lends optimism that high-throughput screenings of large chemical libraries will produce a new generation of antimalarial drugs.

These strategies can rarely be observed directly and must typically be inferred from infection dynamics. Using malaria as a case study, we test previously described methods for inferring transmission stage investment against simulated data generated with a model of within-host infection dynamics, where the true transmission investment is known. We show that existing methods are inadequate and potentially very misleading. The key difficulty lies in separating transmission stages produced by different generations of parasites. We develop a new approach that performs much better on simulated data. Applying this approach to real data from mice infected with a single Plasmodium chabaudi strain, we estimate that transmission investment varies from zero to 20%, with evidence for variable investment over time in some hosts, but not others.

Prevention efforts might reduce HIV incidence but are unlikely to eliminate this disease. We investigated a theoretical strategy of universal voluntary HIV testing and immediate treatment with ART, and examined the conditions under which the HIV epidemic could be driven towards elimination. METHODS We used mathematical models to explore the effect on the case reproduction number (stochastic model) and long-term dynamics of the HIV epidemic (deterministic transmission model) of testing all people in our test-case community (aged 15 years and older) for HIV every year and starting people on ART immediately after they are diagnosed HIV positive. We used data from South Africa as the test case for a generalised epidemic, and assumed that all HIV transmission was heterosexual. FINDINGS The studied strategy could greatly accelerate the transition from the present endemic phase, in which most adults living with HIV are not receiving ART, to an elimination phase, in which most are on ART, within 5 years. It could reduce HIV incidence and mortality to less than one case per 1000 people per year by 2016, or within 10 years of full implementation of the strategy, and reduce the prevalence of HIV to less than 1% within 50 years.

Nuclear cccDNA accumulates as a stable episome organized into minichromosomes by histone and nonhistone proteins. In this study we investigated, by a newly developed sensitive and specific assay, the relationship between viral replication and HBV chromatin assembly, transcription, and interaction with viral and cellular regulatory proteins. METHODS To achieve this aim we coupled a quantitative chromatin immunoprecipitation (ChIP) technique to an established method that allows the amplification of virion-encapsidated HBV genomes after transfection of linear HBV DNA into human hepatoma HuH7 cells. The cccDNA-ChIP technique was also applied to study HBV minichromosome transcriptional regulation in liver tissue from HBV-infected patients. RESULTS The use of anti-acetyl-H4/-H3 specific antibodies to immunoprecipitate transcriptionally active chromatin revealed that HBV replication is regulated by the acetylation status of the cccDNA-bound H3/H4 histones. Class I histone deacetylases inhibitors induced an evident increase of both cccDNA-bound acetylated H4 and HBV replication. Finally, histones hypoacetylation and histone deacetylase 1 recruitment onto the cccDNA in liver tissue correlated with low HBV viremia in hepatitis B patients.

OBJECTIVE The objective of this paper is to test the hypothesis that RA sera react with deiminated histones contained in NETs. METHODS Neutrophils from peripheral blood were stimulated with A23187 and acid treated; NETosis was induced by phorbol myristate acetate, and NET proteins were isolated. Sera were tested by immunoblot on acid extracted proteins from neutrophils and from NETs, and by ELISA on deiminated histone H4 or H4-derived peptides. Bands reactive with RA sera were excised from gels, digested with trypsin and subjected to matrix-assisted laser desorption/ionisation time of flight (MALDI-TOF) analysis, before and after derivatisation to detect citrullinated peptides. RESULTS RA sera reacted with a deiminated antigen of 11 KDa from activated neutrophils, recognised also by anti-H4 and antideiminated H4 antibodies. A similar reactivity was observed with NET proteins. The antigen from neutrophils or NETs was identified as citrullinated H4 by MALDI-TOF analysis. By ELISA, RA sera bound in vitro citrullinated H4. Citrullinated H4 14-34 and 31-50 peptides detected antibodies in 67% and 63% of RA sera and in less than 5% of controls; antibody titre was correlated with anti-CCP2.

What determines the price of fixed income ETFs?
[ { "docid": "183531", "text": "The literal answer to your question 'what determines the price of an ETF' is 'the market'; it is whatever price a buyer is willing to pay and a seller is willing to accept. But if the market price of an ETF share deviates significantly from its NAV, the per-share market value of the securities in its portfolio, then an Authorized Participant can make an arbitrage profit by a transaction (creation or redemption) that pushes the market price toward NAV. Thus as long as the markets are operating and the APs don't vanish in a puff of smoke we can expect price will track NAV. That reduces your question to: why does NAV = market value of the holdings underlying a bond ETF share decrease when the market interest rate rises? Let's consider an example. I'll use US Treasuries because they have very active markets, are treated as risk-free (although that can be debated), and excluding special cases like TIPS and strips are almost perfectly fungible. And I use round numbers for convenience. Let's assume the current market interest rate is 2% and 'Spindoctor 10-year Treasury Fund' opens for business with $100m invested (via APs) in 10-year T-notes with 2% coupon at par and 1m shares issued that are worth $100 each. Now assume the interest rate goes up to 3% (this is an example NOT A PREDICTION); no one wants to pay par for a 2% bond when they can get 3% elsewhere, so its value goes down to about 0.9 of par (not exactly due to the way the arithmetic works but close enough) and Spindoctor shares similarly slide to $90. At this price an investor gets slightly over 2% (coupon*face/basis) plus approximately 1% amortized capital gain (slightly less due to time value) per year so it's competitive with a 3% coupon at par. As you say new bonds are available that pay 3%. But our fund doesn't hold them; we hold old bonds with a face value of $100m but a market value of only $90m. If we sell those bonds now and buy 3% bonds to (try to) replace them, we only get $90m par value of 3% bonds, so now our fund is paying a competitive 3% but NAV is still only $90. At the other extreme, say we hold the 2% bonds to maturity, paying out only 2% interest but letting our NAV increase as the remaining term (duration) and thus discount of the bonds decreases -- assuming the market interest rate doesn't change again, which for 10 years is probably unrealistic (ignoring 2009-2016!). At the end of 10 years the 2% bonds are redeemed at par and our NAV is back to $100 -- but from the investor's point of view they've forgone $10 in interest they could have received from an alternative investment over those 10 years, which is effectively an additional investment, so the original share price of $90 was correct.", "title": "" } ]

Admiral shares of Vanguard funds are charged lower annual expenses than regular shares (yes, all mutual funds charge expenses for fund adninistration that reduce the return that you get, and Vanguard has some of the lowest expense ratios) but Admiral shares are available only for large investments, typically $50K or so.

On the other hand, Exchange-traded funds (ETFs) are fixed baskets of stocks, and you can buy shares in the ETF. These shares are bought and sold through a broker (so you pay a transaction fee each time) but expenses are lower since there is no manager to buy and sell stocks: the basket is fixed. Many ETFs follow specific market indexes (e.g. S&P 500). Another difference between ETFs and mutual funds is that you can buy and sell ETFs at any time of the day just as if you could if you held stocks. With mutual funds, any buy and sell requests made during the day are processed at the end of the day and the value of the shares that you buy or sell is determined by the closing price of the stocks held by the mutual fund.

The assumption is simplistic. What are traditionally referred to as closed-end funds (CEFs), where unit creation and redemption are very tightly controlled, have been around for a long time, and yes, they do often trade at a premium or discount to NAV because the quantity is inflexible. Yet, what is generally meant when the label \"\"ETF\"\" is used (despite CEFs also being both \"\"exchange-traded\"\" and \"\"funds\"\") are those securities which are not just exchange-traded, and funds, but also typically have two specific characteristics: (a) that they are based on some published index, and (b) that a mechanism exists for shares to be created or redeemed by large market participants. These characteristics facilitate efficient pricing through arbitrage. Essentially, when large market participants notice the price of an ETF diverging from the value of the shares held by the fund, new units of the ETF can get created or redeemed in bulk. The divergence quickly narrows as these participants buy or sell ETF units to capture the difference. So, the persistent premium (sometimes dear) or discount (sometimes deep) one can easily witness in the CEF universe tend not to occur with the typical ETF. Much of the time, prices for ETFs will tend to be very close to their net asset value. However, it isn't always the case, so proceed with some caution anyway. Both CEF and ETF providers generally publish information about their funds online. You will want to find out what is the underlying Net Asset Value (NAV) per share, and then you can determine if the market price trades at a premium or a discount to NAV. Assuming little difference in an ETF's price vs. its NAV, the more interesting question to ask about an ETF then becomes whether the NAV itself is a bargain, or not. That means you'll need to be more concerned with what stocks are in the index the fund tracks, and whether those stocks are a bargain, or not, at their current prices. i.e. The ETF is a basket, so look at each thing in the basket. Of course, most people buy ETFs because they don't want to do this kind of analysis and are happy with market average returns.

That demand is what you see on the first day when the general public can start buying the stock. If one is an employee, relative or friend of someone that is offered, \"\"Friends and Family\"\" shares they may be able to buy at the offering price. Pricing of IPO from Wikipedia states around the idea of pricing: A company planning an IPO typically appoints a lead manager, known as a bookrunner, to help it arrive at an appropriate price at which the shares should be issued. There are two primary ways in which the price of an IPO can be determined. Either the company, with the help of its lead managers, fixes a price (\"\"fixed price method\"\"), or the price can be determined through analysis of confidential investor demand data compiled by the bookrunner (\"\"book building\"\"). Historically, some IPOs both globally and in the United States have been underpriced. The effect of \"\"initial underpricing\"\" an IPO is to generate additional interest in the stock when it first becomes publicly traded. Flipping, or quickly selling shares for a profit, can lead to significant gains for investors who have been allocated shares of the IPO at the offering price. However, underpricing an IPO results in lost potential capital for the issuer. One extreme example is theglobe.com IPO which helped fuel the IPO \"\"mania\"\" of the late 90's internet era. Underwritten by Bear Stearns on November 13, 1998, the IPO was priced at $9 per share. The share price quickly increased 1000% after the opening of trading, to a high of $97. Selling pressure from institutional flipping eventually drove the stock back down, and it closed the day at $63. Although the company did raise about $30 million from the offering it is estimated that with the level of demand for the offering and the volume of trading that took place the company might have left upwards of $200 million on the table. The danger of overpricing is also an important consideration. If a stock is offered to the public at a higher price than the market will pay, the underwriters may have trouble meeting their commitments to sell shares. Even if they sell all of the issued shares, the stock may fall in value on the first day of trading. If so, the stock may lose its marketability and hence even more of its value. This could result in losses for investors, many of whom being the most favored clients of the underwriters. Perhaps the best known example of this is the Facebook IPO in 2012. Underwriters, therefore, take many factors into consideration when pricing an IPO, and attempt to reach an offering price that is low enough to stimulate interest in the stock, but high enough to raise an adequate amount of capital for the company. The process of determining an optimal price usually involves the underwriters (\"\"syndicate\"\") arranging share purchase commitments from leading institutional investors. Some researchers (e.g. Geoffrey C., and C. Swift, 2009) believe that the underpricing of IPOs is less a deliberate act on the part of issuers and/or underwriters, than the result of an over-reaction on the part of investors (Friesen & Swift, 2009). One potential method for determining underpricing is through the use of IPO Underpricing Algorithms. This may be useful for seeing the difference in that \"\"theglobe.com\"\" example where the offering price is $9/share yet the stock traded much higher than that initially.\"", "title": "" }, { "docid": "526422", "text": "\"The question is asking for a European equivalent of the so-called \"\"Couch Potato\"\" portfolio. \"\"Couch Potato\"\" portfolio is defined by the two URLs provided in question as, Criteria for fund composition Fixed-income: Regardless of country or supra-national market, the fixed-income fund should have holdings throughout the entire length of the yield curve (most available maturities), as well as being a mix of government, municipal (general obligation), corporate and high-yield bonds. Equity: The common equity position should be in one equity market index fund. It shouldn't be a DAX-30 or CAC-40 or DJIA type fund. Instead, you want a combination of growth and value companies. The fund should have as many holdings as possible, while avoiding too much expense due to transaction costs. You can determine how much is too much by comparing candidate funds with those that are only investing in highly liquid, large company stocks. Why it is easier for U.S. and Canadian couch potatoes It will be easier to find two good funds, at lower cost, if one is investing in a country with sizable markets and its own currency. That's why the Couch Potato strategy lends itself most naturally to the U.S.A, Canada, Japan and probably Australia, Brazil, South Korea and possibly Mexico too. In Europe, pre-EU, any of Germany, France, Spain, Italy or the Scandinavian countries would probably have worked well. The only concern would be (possibly) higher equity transactions costs and certainly larger fixed-income buy-sell spreads, due to smaller and less liquid markets other than Germany. These costs would be experienced by the portfolio manager, and passed on to you, as the investor. For the EU couch potato Remember the criteria, especially part 2, and the intent as described by the Couch Potato name, implying extremely passive investing. You want to choose two funds offered by very stable, reputable fund management companies. You will be re-balancing every six months or a year, only. That is four transactions per year, maximum.

Instead, you need stability and an index fund with a good reputation.

Don't use Vanguard's FTSE ETF or the equivalent, as there will probably be currency and foreign tax concerns, and possibly forex risk. The couch potato strategy requires an emphasis on low fees with high quality funds and brokers (if not buying directly from the fund). As for type of fund, it would be best to choose a fund that is invested in mostly or only EU or EEU (European Economic Union) stocks, and the same for bonds.

An investment trust is an actively managed, closed-end fund that is tradeable on the stock market. \"\"Closed-end\"\" means that there are a fixed number of shares available for trading, so if you wish to buy or sell shares in a closed-end fund you need to find someone willing to sell or buy shares. \"\"Actively managed\"\" means that the assets are selected by the fund managers in the belief that they will perform well. This is in contrast to a \"\"passively managed\"\" fund which simply tracks an underlying index. The closed-end nature of investment trusts means that the share price is not well correlated to the value of the underlying assets. Indeed, almost all UK investment trusts trade at a significant discount to their net asset value. This reflects their historic poor performance and relatively weak liquidity. Of course there are some exceptions to this. Examples of open-end funds are unit trust (US = mutual funds) and ETFs (exchange traded funds). They are \"\"open-end\"\" funds in the sense that the number of shares/units available will change according to demand. Most importantly, the price of a share/unit will be strongly correlated to the net asset value of the underlying portfolio. In general, for an open-end fund, if the net asset value of the fund is X and there are Y shares/units outstanding, then the price of a share/unit will be X/Y. Historic data shows that passively managed funds (index trackers) \"\"always\"\" outperform actively managed funds in the long term. One of the big issues with actively managed funds is they have relatively high management fees. The Peoples Trust will be charging about 1% with a promise that this should come down over time. Compare this to a fee of 0.05% on a large, major market index tracking ETF. Further, the 1% headline fee being touted by Peoples Trust is a somewhat misleading, since they are paying their employees bonuses with shares in the fund. This will cause dilution of the net asset value per share and can be read as addition management fees by proxy. Since competent fund managers will demand high incomes, bonus shares could easily double the management fees, depending on the size of the fund.

This is especially so in countries where interest costs are tax deductible. If we exclude capital losses (i.e. the property sells in future at a price less than it was purchased) or net rental income that doesn't keep up with maintenance, regulatory, taxation, inflation and / or other costs, there is one primary scenario where higher leverage results in lower yields compared to lower leverage, even if rental income keeps up with non-funding costs. This occurs when variable rate financing is used and rates substantially increase. EXPLANATION Borrowers and lenders in different countries have different mortgage rate customs. Some are more likely to have long-term fixed rates; some prefer variable rates; and others are a hybrid, i.e. fixed for a few years and then become variable. If variable rates are used for a mortgage and the reference rates increase substantially, as they did in the US during the 1970s, the borrower can easily become \"\"upside-down,\"\" i.e. owe more on the mortgage than the property is then worth, and have mortgage service costs that exceed the net rental income. Some of those costs aren't easy to pass along to renters, even when there are periodic lease renewals or base rent increases referencing inflation rates. Central banks set policies for what would be the lowest short-term rates in a country that has such a bank. Private sector rates are established broadly by supply and demand for credit and can thus diverge markedly from central bank rates. Over time, the higher finance-carrying-cost-to-net-rental-income ratio should abate as (1) rental market prices change to reflect the costs and (2) the landlord can reinvest his net rental income at a higher rate. In the short-term though, this can result in the landlord having to \"\"eat\"\" the costs making his yield on his leveraged fixed income asset less than what he would have without leverage, even if the property was later sold at same price regardless of financing method. ========== Interestingly, and on the flip side, this is one of the quirks in finance where an accounting liability can become, at least in part, an economic asset. If a landlord borrows at a high loan-to-value ratio for a fixed interest rate for the life of the mortgage and rates, variable and fixed, were to increase substantially, the difference between his original rate and the present rates accrues to him. If he's able to sell the property with the loan attached (which is not uncommon for commercial, industrial and sometimes municipal real estate), the buyer will be assuming a liability with a lower carrying cost than his present alternatives and will hence pay a higher price for the property than if it were unleveraged. With long-term rates in many economically advanced countries at historic lows, if a borrower today were to take a long-term fixed rate loan and rates shortly after increased substantially, he may have an instant profit in this scenario even if his property hasn't increased in value.\"", "title": "" }, { "docid": "330729", "text": "Any ETF has expenses, including fees, and those are taken out of the assets of the fund as spelled out in the prospectus.

As you approach 45-50, you should slowly reduce your allocation to risky assets and put it in safe haven assets such as fixed income and cash.

Part of the history of housing prices was the non-bubble component of the bubble. To be clear, there was a housing bubble and crash.

A middle class earner, $60K/yr couple, using 25% of their income, the normal percent for a qualified mortgage, was able to afford $142K for the mortgage payment. At 10% fixed rate. This meant that after down payment, they were buying a house at $175K or so, which was above median home pricing. Years later, obviously, this wasn't a step function, with a rate of 4%, and ignoring any potential rise of income, as in real term, income was pretty stagnant, the same $1250/mo could pay for a $260K mortgage. If you want to say that taxes and insurance would push that down a bit, sure, drop the loan to $240K, and the house price is $300K. My thesis ('my belief' or 'proposal', I haven't written a scholarly paper, yet) is that the relationship between median home price and median income is easily calculated based on current 30 year fixed rate loans. For all the talk of housing prices, this is the long term number. Housing cannot exceed income inflation long term as it would creep up as a percent of income and slow demand.

Neurologic and reproductive endocrine phenotypes were characterized in detail. The effects of sequence variants and the presence of an epistatic interaction were tested in a zebrafish model. RESULTS Digenic homozygous mutations in RNF216 and OTUD4, which encode a ubiquitin E3 ligase and a deubiquitinase, respectively, were found in three affected siblings in a consanguineous family. Additional screening identified compound heterozygous truncating mutations in RNF216 in an unrelated patient and single heterozygous deleterious mutations in four other patients. Knockdown of rnf216 or otud4 in zebrafish embryos induced defects in the eye, optic tectum, and cerebellum; combinatorial suppression of both genes exacerbated these phenotypes, which were rescued by nonmutant, but not mutant, human RNF216 or OTUD4 messenger RNA.

Clock gene transcription remained arrhythmic in tumors irrespective of feeding schedule or diet. Yet, MT upregulated or downregulated the expression of 423 tumor genes, according to CT. Moreover, 36 genes involved in cellular stress, cell cycle, and metabolism were upregulated at one CT and downregulated 12 h apart. MT induced >10-fold circadian expression of Hspa8, Cirbp, and Ccna2 in tumors. Corticosterone or IGF-I patterns played no role in tumor growth inhibition. In contrast, MT consistently doubled the circadian amplitude of body temperature. Peak and trough respectively corresponded to peak expressions of Hspa8 and Cirbp in tumors. The reinforcement of the host circadian timing system with MT induced 24-hour rhythmic expression of critical genes in clock-deficient tumors, which translated into cancer growth inhibition.

OBJECTIVE To test the hypothesis that elevated levels of inflammatory biomarkers in individuals with stable COPD are associated with an increased risk of having exacerbations. DESIGN, SETTING, AND PARTICIPANTS Prospective cohort study examining 61,650 participants with spirometry measurements from the Copenhagen City Heart Study (2001-2003) and the Copenhagen General Population Study (2003-2008). Of these, 6574 had COPD, defined as a ratio between forced expiratory volume in 1 second (FEV1) and forced vital capacity below 0.7. MAIN OUTCOMES AND MEASURES Baseline levels of C-reactive protein (CRP) and fibrinogen and leukocyte count were measured in participants at a time when they were not experiencing symptoms of exacerbations. Exacerbations were recorded and defined as short-course treatment with oral corticosteroids alone or in combination with an antibiotic or as a hospital admission due to COPD. Levels of CRP and fibrinogen and leukocyte count were defined as high or low according to cut points of 3 mg/L, 14 μmol/L, and 9 ×10(9)/L, respectively. RESULTS During follow-up, 3083 exacerbations were recorded (mean, 0.5/participant). In the first year of follow-up, multivariable-adjusted odds ratios for having frequent exacerbations were 1.2 (95% CI, 0.7-2.2; 17 events/1000 person-years) for individuals with 1 high biomarker, 1.7 (95% CI, 0.9-3.2; 32 events/1000 person-years) for individuals with 2 high biomarkers, and 3.7 (95% CI, 1.9-7.4; 81 events/1000 person-years) for individuals with 3 high biomarkers compared with individuals who had no elevated biomarkers (9 events/1000 person-years; trend: P = 2 × 10(-5)). Corresponding hazard ratios using maximum follow-up time were 1.4 (95% CI, 1.1-1.8), 1.6 (95% CI, 1.3-2.2), and 2.5 (95% CI, 1.8-3.4), respectively (trend: P = 1 × 10(-8)). The addition of inflammatory biomarkers to a basic model including age, sex, FEV1 percent predicted, smoking, use of any inhaled medication, body mass index, history of previous exacerbations, and time since most recent prior exacerbation improved the C statistics from 0.71 to 0.73 (comparison: P = 9 × 10(-5)). Relative risks were consistent in those with milder COPD, in those with no history of frequent exacerbations, and in the 2 studies separately. The highest 5-year absolute risks of having frequent exacerbations in those with 3 high biomarkers (vs no high biomarkers) were 62% (vs 24%) for those with Global Initiative for Chronic Obstructive Lung Disease (GOLD) grades C-D (n = 558), 98% (vs 64%) in those with a history of frequent exacerbations (n = 127), and 52% (vs 15%) for those with GOLD grades 3-4 (n = 465).

We reported previously that both EGFR- and Her2-overexpressing tumors are sensitive to the new EGFR-selective TK inhibitor gefitinib (ZD1839, \"Iressa\"), and sensitivity to this agent correlated with its ability to down-regulate Akt. However, EGFR-overexpressing MDA-468 cells, which lack PTEN function, are resistant to ZD1839, and ZD1839 is unable to down-regulate Akt activity in these cells. EXPERIMENTAL DESIGN To study the role of PTEN function, we generated MDA468 cells with tet-inducible PTEN expression. RESULTS We show here that the resistance of MDA-468 cells to ZD1839 is attributable to EGFR-independent constitutive Akt activation caused by loss of PTEN function in these cells. Reconstitution of PTEN function through tet-inducible expression restores ZD1839 sensitivity to these cells and reestablishes EGFR-stimulated Akt signaling. Although restoration of PTEN function to tumors is difficult to implement clinically, much of the effects of PTEN loss are attributable to overactive PI3K/Akt pathway signaling, and this overactivity can be modulated by pharmacologic approaches. We show here that pharmacologic down-regulation of constitutive PI3K/Akt pathway signaling using the PI3K inhibitor LY294002 similarly restores EGFR-stimulated Akt signaling and sensitizes MDA-468 cells to ZD1839. CONCLUSIONS Sensitivity to ZD1839 requires intact growth factor receptor-stimulated Akt signaling activity. PTEN loss leads to uncoupling of this signaling pathway and results in ZD1839 resistance, which can be reversed with reintroduction of PTEN or pharmacologic down-regulation of constitutive PI3K/Akt pathway activity.

It acts as a key downstream target of both peroxisome proliferator-activated receptor α and γ, the agonists of which have been used for lipid lowering and insulin sensitization, respectively. However, the role of FGF21 in the cardiovascular system remains elusive. METHODS AND RESULTS The roles of FGF21 in atherosclerosis were investigated by evaluating the impact of FGF21 deficiency and replenishment with recombinant FGF21 in apolipoprotein E(-/-) mice. FGF21 deficiency causes a marked exacerbation of atherosclerotic plaque formation and premature death in apolipoprotein E(-/-) mice, which is accompanied by hypoadiponectinemia and severe hypercholesterolemia. Replenishment of FGF21 protects against atherosclerosis in apolipoprotein E(-/-)mice via 2 independent mechanisms, inducing the adipocyte production of adiponectin, which in turn acts on the blood vessels to inhibit neointima formation and macrophage inflammation, and suppressing the hepatic expression of the transcription factor sterol regulatory element-binding protein-2, thereby leading to reduced cholesterol synthesis and attenuation of hypercholesterolemia. Chronic treatment with adiponectin partially reverses atherosclerosis without obvious effects on hypercholesterolemia in FGF21-deficient apolipoprotein E(-/-) mice. By contrast, the cholesterol-lowering effects of FGF21 are abrogated by hepatic expression of sterol regulatory element-binding protein-2.

We hypothesized that overexpression of SLC1A5 occurs to meet the metabolic demand for lung cancer cell growth and survival. EXPERIMENTAL DESIGN To test our hypothesis, we first analyzed the protein expression of SLC1A5 in archival lung cancer tissues by immunohistochemistry and immunoblotting (N = 98) and in cell lines (N = 36). To examine SLC1A5 involvement in amino acid transportation, we conducted kinetic analysis of l-glutamine (Gln) uptake in lung cancer cell lines in the presence and absence of a pharmacologic inhibitor of SLC1A5, gamma-l-Glutamyl-p-Nitroanilide (GPNA). Finally, we examined the effect of Gln deprivation and uptake inhibition on cell growth, cell-cycle progression, and growth signaling pathways of five lung cancer cell lines. RESULTS Our results show that (i) SLC1A5 protein is expressed in 95% of squamous cell carcinomas (SCC), 74% of adenocarcinomas (ADC), and 50% of neuroendocrine tumors; (ii) SLC1A5 is located at the cytoplasmic membrane and is significantly associated with SCC histology and male gender; (iii) 68% of Gln is transported in a Na(+)-dependent manner, 50% of which is attributed to SLC1A5 activity; and (iv) pharmacologic and genetic targeting of SLC1A5 decreased cell growth and viability in lung cancer cells, an effect mediated in part by mTOR signaling.

Similarly, the length of extranucleosomal DNA affected the stable contact of ISW2 with this same internal nucleosomal site, with the optimal length being 70 to 85 bp.

H3K36 trimethylation (H3K36me3) is deposited onto the nucleosomes in the transcribed regions after RNA polymerase II elongation. In yeast, this mark in turn recruits epigenetic regulators to reset the chromatin to a relatively repressive state, thus suppressing cryptic transcription. However, much less is known about the role of H3K36me3 in transcription regulation in mammals. This is further complicated by the transcription-coupled incorporation of the histone variant H3.3 in gene bodies.

Structural studies show that in addition to the trimethyl-lysine binding by an aromatic cage within the PWWP domain, the H3.3-dependent recognition is mediated by the encapsulation of the H3.3-specific ‘Ser 31’ residue in a composite pocket formed by the tandem bromo–PWWP domains of ZMYND11. Chromatin immunoprecipitation followed by sequencing shows a genome-wide co-localization of ZMYND11 with H3K36me3 and H3.3 in gene bodies, and its occupancy requires the pre-deposition of H3.3K36me3. Although ZMYND11 is associated with highly expressed genes, it functions as an unconventional transcription co-repressor by modulating RNA polymerase II at the elongation stage. ZMYND11 is critical for the repression of a transcriptional program that is essential for tumour cell growth; low expression levels of ZMYND11 in breast cancer patients correlate with worse prognosis.

Starving Cancer with Methionine Restriction
[ { "docid": "MED-3715", "text": "INTRODUCTION: Questions have recently arisen in the popular press about the association between specific sexual behaviors, namely, fellatio and cunnilingus, with head and neck cancers. Although there has been an overall decline in the incidence of head and neck cancers over the past 25 years, there has been a shift in the distribution of these cancers toward a particular type known as oral squamous cell carcinomas (OSCCs), and a younger demographic. These particular cancers, OSCCs, have been shown to be associated with the human papillomavirus (HPV). Several researchers have suggested that this shift in the epidemiology of head and neck cancers might be attributable to changing sexual practices. While this speculation has caught on in the popular press, there are several interesting contradictions in the existing evidence that suggest this conclusion might be premature and overreached. AIM: The intent of this article is to help clarify the issues so that sexual medicine professionals can give accurate and up-to-date information to their patients. MAIN OUTCOME MEASURES: This is a review article; no outcome data are reported. This is a review article; no measures were collected. METHODS: Pubmed search on HPV, oral sex, oral cancers, and OSCCs. RESULTS: One hundred ninety-six articles on HPV were found; 63 articles on oral sex, 55 on oral cancer, and 5 articles on OSCCs were identified as relevant. CONCLUSIONS: HPV infections occur commonly and are usually cleared within 18 months, thus HPV infection should not be a cause for concern among monogamous couples with a rich and varied sex life as long as the sexual system remains closed and other immune compromising factors are not present. HPV becomes a concern in the context of immune system compromise and infection persistence.

Glycolytic metabolism is markedly accelerated in cancer cells, causing the accumulation of glucose (a reducing sugar) and methionine (an amino acid), which can non-enzymatically react and form carcinogenic substances. There is speculation that this reaction produces gaseous sulfur-containing compounds in tumour tissue. The aims of this study were to clarify the products in tumour and to investigate their effect on tumour proliferation. METHODS: Products formed in the reaction between glucose and methionine or its metabolites were analysed in vitro using gas chromatography. Flatus samples from patients with colon cancer and exhaled air samples from patients with lung cancer were analysed using near-edge x-ray fine adsorption structure spectroscopy and compared with those from healthy individuals. The tumour proliferation rates of mice into which HT29 human colon cancer cells had been implanted were compared with those of mice in which the cancer cells were surrounded by sodium hyaluronate gel to prevent diffusion of gaseous material into the healthy cells. RESULTS: Gaseous sulfur-containing compounds such as methanethiol and hydrogen sulfide were produced when glucose was allowed to react with methionine or its metabolites homocysteine or cysteine. Near-edge x-ray fine adsorption structure spectroscopy showed that the concentrations of sulfur-containing compounds in the samples of flatus from patients with colon cancer and in the samples of exhaled air from patients with lung cancer were significantly higher than in those from healthy individuals. Animal experiments showed that preventing the diffusion of sulfur-containing compounds had a pronounced antitumour effect. CONCLUSIONS: Gaseous sulfur-containing compounds are the main products in tumours and preventing the diffusion of these compounds reduces the tumour proliferation rate, which suggests the possibility of a new approach to cancer treatment.", "title": "Generation of gaseous sulfur-containing compounds in tumour tissue and suppression of gas diffusion as an antitumour treatment." }, { "docid": "MED-3732", "text": "Background Endoscopic submucosal dissection (ESD) is an advanced technique of therapeutic endoscopy alternative to endoscopic mucosal resection (EMR) for superficial gastrointestinal neoplasms >2 cm. ESD allows for the direct dissection of the submucosa and large lesions can be resected en bloc. ESD is not limited by resection size, increases histologically complete resection rates and may reduce the local recurrence. Nevertheless, the technique is time-consuming, technically demanding and associated with a high complication rate. To reduce the risk of complications, different devices and technical advances have been proposed with conflicting results and, still, ESD en bloc resections of huge lesions are associated with increased complications. Case Presentation We successfully used a combined ESD/EMR technique for huge rectal laterally spreading tumors (LSTs). ESD was used for circumferential resection of 2/3 of the lesion followed by piecemeal resection (2-3 pieces) of the central part of the tumour. In all three patients we obtained the complete dissection of the polyp and the complete histological evaluation in absence of complications and recurrence at 6 months' follow up. Conclusions In the treatment of rectal LSTs, the combined treatment - ESD/EMR resection may be considered a suitable therapeutic option, indicated in selected cases as an alternative to surgery, in which the two techniques are neither reliable nor safe separately.

The reason tumors have antigens may be that tumors do not develop in vivo in the absence of at least a minimal immune reaction; in this sense, cancer may be considered an autoimmune disease. This review, based largely on the work of our own laboratory, outlines the data showing that the titration of anti-tumor immunity exhibits the phenomenon of hormesis, i.e. the dose-response curve is non-linear such that low levels of immunity are generally stimulatory but larger quantities of the same immune reactants may inhibit tumor growth. Evidence is also reviewed that suggests that the immune response may vary qualitatively and quantitatively during progression, such that there seems to be, during oncogenesis, a very low level of immune reaction that aids initial tumor growth, followed by a larger reaction that may cause remission of early neoplasms, followed, if the neoplasm survives, by a relative immunologic tolerance to the tumor that may be dependent, at least in part, on suppressor cells.

The first pandemic, induced by beriberi, was caused by the industrial revolution altering the nutritional composition of rice. By 1892 a simple working knowledge, then at hand, could have terminated the beriberi plague; however, orthodox medicine being then enchanted with the false concept that all disease was caused by germs, permitted millions of Asians to die needlessly of beriberi by refusing to tell them to eat rice bran or to drink rice bran tea.

The unnatural trans-trans isomer of linoleic acid, which had never been in human food prior to 1920 and which entered our food in margarines and refined oils, blocked the conversion of natural cis-cis linoleic acid to prostaglandin E1, which tends to prevent MI, both by acting as a vasodilator and by minimizing platelet aggregation. Harmful lactones were also introduced into our food, increasing the risk of MI by decreasing the fibrinolytic activity of our blood. The oil seed industry also introduced into our diet free radical lipid peroxides that make the myocardium more vulnerable to infarction.

Soy protein, as well as many other vegan proteins, are higher in non-essential amino acids than most animal-derived food proteins, and as a result should preferentially favor glucagon production. Acting on hepatocytes, glucagon promotes (and insulin inhibits) cAMP-dependent mechanisms that down-regulate lipogenic enzymes and cholesterol synthesis, while up-regulating hepatic LDL receptors and production of the IGF-I antagonist IGFBP-1. The insulin-sensitizing properties of many vegan diets--high in fiber, low in saturated fat--should amplify these effects by down-regulating insulin secretion. Additionally, the relatively low essential amino acid content of some vegan diets may decrease hepatic IGF-I synthesis. Thus, diets featuring vegan proteins can be expected to lower elevated serum lipid levels, promote weight loss, and decrease circulating IGF-I activity. The latter effect should impede cancer induction (as is seen in animal studies with soy protein), lessen neutrophil-mediated inflammatory damage, and slow growth and maturation in children. In fact, vegans tend to have low serum lipids, lean physiques, shorter stature, later puberty, and decreased risk for certain prominent 'Western' cancers; a vegan diet has documented clinical efficacy in rheumatoid arthritis. Low-fat vegan diets may be especially protective in regard to cancers linked to insulin resistance--namely, breast and colon cancer--as well as prostate cancer; conversely, the high IGF-I activity associated with heavy ingestion of animal products may be largely responsible for the epidemic of 'Western' cancers in wealthy societies. Increased phytochemical intake is also likely to contribute to the reduction of cancer risk in vegans. Regression of coronary stenoses has been documented during low-fat vegan diets coupled with exercise training; such regimens also tend to markedly improve diabetic control and lower elevated blood pressure. Risk of many other degenerative disorders may be decreased in vegans, although reduced growth factor activity may be responsible for an increased risk of hemorrhagic stroke. By altering the glucagon/insulin balance, it is conceivable that supplemental intakes of key non-essential amino acids could enable omnivores to enjoy some of the health advantages of a vegan diet. An unnecessarily high intake of essential amino acids--either in the absolute sense or relative to total dietary protein--may prove to be as grave a risk factor for 'Western' degenerative diseases as is excessive fat intake.", "title": "Vegan proteins may reduce risk of cancer, obesity, and cardiovascular disease by promoting increased glucagon activity." }, { "docid": "MED-3721", "text": "Reduced expression of proapoptotic and terminal differentiation genes in conjunction with increased levels of the proinflammatory and angiogenesis-inducing enzymes, cyclooxygenase 2 (COX-2) and inducible nitric oxide synthase (iNOS), correlate with malignant transformation of oral intraepithelial neoplasia (IEN).

BLV-infected cells are present in marketed beef and dairy products. In the decade after the discovery of BLV in 1969, studies using agar gel immunodiffusion and complement fixation assays failed to find antibodies to BLV in human sera. This led to the prevailing opinion that exposure of humans to BLV and/or the potential for infection are not significant and therefore the virus is not a public health hazard. We reexamined this issue using more sensitive immunological techniques available today. Using immunoblotting to test the sera of 257 humans for antibodies of four isotypes (IgG1, IgM, IgA, and IgG4) to the BLV capsid antigen (p24), we detected at least one antibody isotype reactive with BLV in 74% of the human sera tested. The specificity of the reactivity was strongly suggested by competition studies and by ruling out cross-reacting antibodies to other chronic human viruses. Our results suggest that antibodies reactive with the BLV capsid antigen may serve as a biomarker for exposure to BLV and this exposure may be widespread. The results do not necessarily mean that humans are actually infected with BLV; the antibodies could be a response to heat-denatured BLV antigens consumed in food.

This evidence comes from a variety of sources including clinical-pathological investigations in women that show a correlation between the intensity of lymphocytic infiltration into the tumour mass with poor prognosis, studies in breast cancer patients that demonstrate a similar correlation between delayed hypersensitivity reactivity or in vitro assays of immune reactivity to tumour cell membranes or non-specific antigens and poor prognosis, and analyses of cancer incidence in chronically immunosuppressed, kidney transplant recipients who develop an unexpectedly low incidence of breast cancer. The overall conclusions from these human studies are corroborated by observations in mouse mammary tumour models that also demonstrate immune enhancement of breast cell proliferation in vitro and of breast cancer development in vivo.

Therefore, we evaluated the effects of comprehensive lifestyle changes on prostate specific antigen (PSA), treatment trends and serum stimulated LNCaP cell growth in men with early, biopsy proven prostate cancer after 1 year. MATERIALS AND METHODS: Patient recruitment was limited to men who had chosen not to undergo any conventional treatment, which provided an unusual opportunity to have a nonintervention randomized control group to avoid the confounding effects of interventions such as radiation, surgery or androgen deprivation therapy. A total of 93 volunteers with serum PSA 4 to 10 ng/ml and cancer Gleason scores less than 7 were randomly assigned to an experimental group that was asked to make comprehensive lifestyle changes or to a usual care control group. RESULTS: None of the experimental group patients but 6 control patients underwent conventional treatment due to an increase in PSA and/or progression of disease on magnetic resonance imaging. PSA decreased 4% in the experimental group but increased 6% in the control group (p = 0.016). The growth of LNCaP prostate cancer cells (American Type Culture Collection, Manassas, Virginia) was inhibited almost 8 times more by serum from the experimental than from the control group (70% vs 9%, p <0.001).

New therapeutic strategies must be identified, and the metabolic abnormalities of cancer cells offer such opportunities. Many human cancer cell lines and primary tumors have absolute requirements for methionine, an essential amino acid. In contrast, normal cells are relatively resistant to exogenous methionine restriction. The biochemical mechanism for methionine dependency has been studied extensively, but the fundamental mechanism remains unclear. A number of investigators have attempted to exploit the methionine dependence of tumors for therapeutic effects in vivo. To reduce in vivo methionine in plasma and tumours, dietary and pharmacological treatments have been used. Methionine-free diet or methionine-deprived total parenteral nutrition causes regression of a variety of animal tumours. Alternatively, methionine depletion was achieved by the use of methioninase. This enzyme specifically degrades methionine and inhibits tumour growth in preclinical models. Because of potential toxicity and quality of life problems, prolonged methionine restriction with diet or with methioninase is not suitable for clinical use. Methionine restriction may find greater application in association with various chemotherapeutic agents. Several preclinical studies have demonstrated synergy between methionine restriction and various cytotoxic chemotherapy drugs.

We randomly assigned 75 patients identified by endoscopy to have dysplastic esophageal premalignant lesions to receive freeze-dried strawberry powder at either 30 g/d (37 patients) or 60 g/d (38 patients) for six months; the powder was mixed with water and drunk.

Methods Identification and quantitation of CS, CG, and CR in RE was performed by mass spectroscopy and HPLC. RE:triacetyl-β-cyclodextrin (TA-β-CD) inclusion complex (IC) was prepared by a kneading method and characterized by X-ray diffraction (XRD), nuclear magnetic resonance spectroscopy (NMR) and UV-visible spectroscopy. RE or RE:TA-β-CD IC-loaded PLGA or PLA implants were prepared by a solvent extrusion method. In vitro and in vivo controlled release studies were conducted in phosphate-buffered saline Tween-80 (pH 7.4, 37°C) and after subcutaneous administration in male Sprague-Dawley rats, respectively. Anthocyanins were quantified by HPLC at 520 nm. Results The content of CS, CG, and CR in RE was 0.2, 1.5, and 3.5 wt%, respectively. The chemical stability of anthocyanins in solution was determined to be pH-dependent, and their degradation rate increased with an increase in pH from 2.4 to 7.4. PLGA/PLA millicylindrical implants loaded with 5 or 10 wt% RE exhibited a high initial burst and short release duration of anthocyanins (35–52 and 80–100% CG + CR release after 1 and 14 days, respectively). The cause for rapid anthocyanins release was linked to higher polymer water uptake and porosity associated with the high osmolytic components of large non-anthocyanin fraction of RE. XRD, 1H NMR and UV-visible spectroscopy indicated that the non-anthocyanin fraction molecules of RE formed an IC with TA-β-CD, decreasing the hydrophilicity of RE. Formation of an IC with hydrophobic carrier, TA-β-CD, provided better in vitro/in vivo sustained release of FBR anthocyanins (16–24 and 97–99% CG + CR release, respectively, after 1 and 28 days from 20 wt% RE:TA-β-CD IC/PLA implants) over 1 month, owing to reduced polymer water uptake and porosity.

Oxidation of proteins has been proposed to be one of the basic mechanisms linking oxygen radicals with the basic aging process. If oxidative damage to proteins is involved in aging, long-lived animals (which age slowly) should show lower levels of markers of this kind of damage than short-lived ones. However, this possibility has not been investigated yet. In this study, steady-state levels of markers of different kinds of protein damage--oxidation (glutamic and aminoadipic semialdehydes), mixed glyco- and lipoxidation (carboxymethyl- and carboxyethyllysine), lipoxidation (malondialdehydelysine) and amino acid composition--were measured in the heart of eight mammalian species ranging in maximum life span (MLSP) from 3.5 to 46 years. Oxidation markers were directly correlated with MLSP across species. Mixed glyco- and lipoxidation markers did not correlate with MLSP. However, the lipoxidation marker malondialdehydelysine was inversely correlated with MLSP (r2=0.85; P<0.001). The amino acid compositional analysis revealed that methionine is the only amino acid strongly correlated MLSP and that such correlation is negative (r2=0.93; P<0.001). This trait may contribute to lower steady-state levels of oxidized methionine residues in cellular proteins.

Design Exhaled breath and watery stool samples were obtained from patients with CRC and from healthy controls prior to colonoscopy. Each test group consisted of one sample from a patient with CRC and four control samples from volunteers without cancer. These five samples were randomly and separately placed into five boxes. A Labrador retriever specially trained in scent detection of cancer and a handler cooperated in the tests. The dog first smelled a standard breath sample from a patient with CRC, then smelled each sample station and sat down in front of the station in which a cancer scent was detected. Results 33 and 37 groups of breath and watery stool samples, respectively, were tested. Among patients with CRC and controls, the sensitivity of canine scent detection of breath samples compared with conventional diagnosis by colonoscopy was 0.91 and the specificity was 0.99.

In order to determine whether methionine dependence occurs in fresh patient tumors as well as whether methionine dependence occurs in fresh patient tumors as well as in cell lines we took advantage of the technique of sponge-gel-supported histoculture to grow tumors directly from surgery. We then measured nuclear DNA content by image analysis to determine the cell cycle position in MET-HCY+ compared to MET+HCY- medium in 21 human patient tumors. Human tumor cell lines found to be methionine dependent by cell count were used as positive controls and were found to have marked reduction of cells in G1 compared to total cells in the cell cycle in MET-HCY+ medium with respect to the G1: total cell ratio in MET+HCY- medium. Therefore late cell cycle arrest was used as a marker of methionine dependence for histocultured patient tumors. We found that 5 human tumors of 21, including tumors of the colon, breast, ovary, prostate, and a melanoma, were methionine dependent based on cell cycle analysis.

Chitin is an eukaryotic extracellular aminosugar biopolymer, massively produced by most fungal systems and by invertebrates, notably arthropods. Being an integral supportive component in fungal cell wall, insect cuticle, and nematode egg shell, chitin has been considered as a selective target for pesticide action. Throughout the elaborate processes of chitin formation and deposition, only the polymerization events associated with the cell membrane compartment are so far available for chemical interference. Currently, the actinomycetes-derived nucleoside peptide fungicides such as the polyoxins and the insecticidal benzoylaryl ureas have reached commercial pesticide status. The polyoxins and other structurally-related antibiotics like nikkomycins are strong competitive inhibitors of the polymerizing enzyme chitin synthase. The exact biochemical lesion inflicted by the benzoylaryl ureas is still elusive, but a post-polymerization event, such as translocation of chitin chains across the cell membrane, is suggested. Hydrolytic degradation of the chitin polymer is essential for hyphal growth, branching, and septum formation in fungal systems as well as for the normal molting of arthropods. Recently, insect chitinase activity was strongly and specifically suppressed by allosamidin, an actimomycetes-derived metabolite.

It has been observed that protein restriction also decreases mtROS generation and oxidative stress in rat liver, whereas neither carbohydrate nor lipid restriction change these parameters. This is interesting because protein restriction also increases maximum longevity in rodents (although to a lower extent than DR) and is a much more practicable intervention for humans than DR, whereas neither carbohydrate nor lipid restriction seem to change rodent longevity. Moreover, it has been found that isocaloric methionine restriction also decreases mtROS generation and oxidative stress in rodent tissues, and this manipulation also increases maximum longevity in rats and mice.

However, few prospective studies have investigated one-carbon metabolism in relation to prostate cancer risk, and the results have been conflicting. The aim of this study was to do a comprehensive investigation of the components of one-carbon metabolism in relation to prostate cancer risk. A panel of seven circulating B vitamins and related metabolites was selected, most of which have not been studied before. MATERIALS AND METHODS: We analyzed plasma concentrations of betaine, choline, cysteine, methionine, methylmalonic acid (MMA), vitamin B2, and vitamin B6 in 561 cases and 1,034 controls matched for age and recruitment date, nested within the population-based Northern Sweden Health and Disease Cohort. Relative risks of prostate cancer were estimated by conditional logistic regression. RESULTS: Positive associations with prostate cancer risk were observed for choline and vitamin B2, and an inverse association was observed for MMA. The relative risks for a doubling in concentrations were 1.46 [95% confidence interval (95% CI), 1.04-2.05; P(trend) = 0.03] for choline, 1.11 (95% CI, 1.00-1.23; P(trend) = 0.04) for vitamin B2, and 0.78 (95% CI, 0.63-0.97; P(trend) = 0.03) for MMA.

RESULTS: The average duration on the diet was 34 days (range 21 to 77), during which time significant decreases were observed in total serum cholesterol (201 +/- 39 mg/dL to 174 +/- 42 mg/dL), total testosterone (422 +/- 122 ng/dL to 360 +/- 128 ng/dL), and free androgen index (36.3% +/- 18.9% to 29.3% +/- 16.8%) (all P <0.05).

The nutrient-sensitive kinase mTORC1 is upregulated in nearly 100% of advanced human PCas. Oncogenic mTORC1 signaling activates key subsets of mRNAs that cooperate in distinct steps of PCa initiation and progression. Epidemiological evidence points to increased dairy protein consumption as a major dietary risk factor for the development of PCa. mTORC1 is a master regulator of protein synthesis, lipid synthesis and autophagy pathways that couple nutrient sensing to cell growth and cancer. This review provides evidence that PCa initiation and progression are promoted by cow´s milk, but not human milk, stimulation of mTORC1 signaling. Mammalian milk is presented as an endocrine signaling system, which activates mTORC1, promotes cell growth and proliferation and suppresses autophagy. Naturally, milk-mediated mTORC1 signaling is restricted only to the postnatal growth phase of mammals. However, persistent consumption of cow´s milk proteins in humans provide highly insulinotropic branched-chain amino acids (BCAAs) provided by milk´s fast hydrolysable whey proteins, which elevate postprandial plasma insulin levels, and increase hepatic IGF-1 plasma concentrations by casein-derived amino acids. BCAAs, insulin and IGF-1 are pivotal activating signals of mTORC1. Increased cow´s milk protein-mediated mTORC1 signaling along with constant exposure to commercial cow´s milk estrogens derived from pregnant cows may explain the observed association between high dairy consumption and increased risk of PCa in Westernized societies. As well-balanced mTORC1-signaling plays an important role in appropriate prostate morphogenesis and differentiation, exaggerated mTORC1-signaling by high cow´s milk consumption predominantly during critical growth phases of prostate development and differentiation may exert long-term adverse effects on prostate health.

RESULTS: In multivariate-logistic regression models controlling for breast cancer risk factors, women with NPL had a significantly lower prevalence of breast cancer than women with LP (odds ratio, 0.43; 95% confidence interval, 0.21-0.85). We observed little difference in these associations when restricting to postmenopausal women, non-shift workers or when excluding women diagnosed with breast cancer within 2 or 4 years of onset of blindness. Blind women with NPL appear to have a lower risk of breast cancer, compared to blind women with LP.

A small number of studies have suggested that flaxseed-supplemented, fat-restricted diets may thwart prostate cancer growth in both animals and humans. Unknown, however, is the potential effect of such a diet on benign prostatic epithelium. METHODS: We undertook a pilot study to explore whether a flaxseed-supplemented, fat-restricted diet affects the proliferation rates in benign epithelium. We also explored the effects on circulating levels of prostate-specific antigen (PSA), total testosterone, and cholesterol. Fifteen men who were scheduled to undergo repeat prostate biopsy were instructed to follow a low-fat (less than 20% kcal), flaxseed-supplemented (30 g/day) diet and were provided with a supply of flaxseed to last throughout the 6-month intervention period. The PSA, total testosterone, and cholesterol levels were determined at baseline and at 6 months of follow-up. Reports from the original and repeat biopsies were compared, and proliferation (MIB-1) rates were quantified in the benign prostatic epithelium. RESULTS: Statistically significant decreases in PSA (8.47 +/- 3.82 to 5.72 +/- 3.16 ng/mL; P = 0.0002) and cholesterol (241.1 +/- 30.8 to 213.3 +/- 51.2 mg/dL; P = 0.012) were observed. No statistically significant change was seen in total testosterone (434.5 +/- 143.6 to 428.3 +/- 92.5 ng/dL). Although 6-month repeat biopsies were not performed in 2 cases because of PSA normalization, of the 13 men who underwent repeat biopsy, the proliferation rates in the benign epithelium decreased significantly from 0.022 +/- 0.027 at baseline to 0.007 +/- 0.014 at 6 months of follow-up (P = 0.0168). CONCLUSIONS: These pilot data suggest that a flaxseed-supplemented, fat-restricted diet may affect the biology of the prostate and associated biomarkers.

Information on dietary intakes was collected through in-person interviews with a semi-quantitative food frequency questionnaire and was converted into nutrient intakes. Odds ratios and 95% confidence intervals were estimated by unconditional logistic regression. Results Among pre-menopausal women, higher intake of soluble fiber (highest versus lowest quartile of intake) was associated with a significantly reduced risk of breast cancer (OR = 0.38, 95% CI, 0.15–0.97, Ptrend = 0.08).

However, inconsistent results from many studies have not been able to conclusively establish an inverse association between fruit and vegetable intake and overall cancer risk. METHODS: We conducted a prospective analysis of the European Prospective Investigation into Cancer and Nutrition (EPIC) cohort to assess relationships between intake of total fruits, total vegetables, and total fruits and vegetables combined and cancer risk during 1992-2000. Detailed information on the dietary habit and lifestyle variables of the cohort was obtained. Cancer incidence and mortality data were ascertained, and hazard ratios (HRs) and 95% confidence intervals (CIs) were estimated using multivariable Cox regression models. Analyses were also conducted for cancers associated with tobacco and alcohol after stratification for tobacco smoking and alcohol drinking. RESULTS: Of the initial 142 605 men and 335 873 women included in the study, 9604 men and 21 000 women were identified with cancer after a median follow-up of 8.7 years. The crude cancer incidence rates were 7.9 per 1000 person-years in men and 7.1 per 1000 person-years in women. Associations between reduced cancer risk and increased intake of total fruits and vegetables combined and total vegetables for the entire cohort were similar (200 g/d increased intake of fruits and vegetables combined, HR = 0.97, 95% CI = 0.96 to 0.99; 100 g/d increased intake of total vegetables, HR = 0.98, 95% CI = 0.97 to 0.99); intake of fruits showed a weaker inverse association (100 g/d increased intake of total fruits, HR = 0.99, 95% CI = 0.98 to 1.00). The reduced risk of cancer associated with high vegetable intake was restricted to women (HR = 0.98, 95% CI = 0.97 to 0.99).

DESIGN: The chronic sleep restriction experiment involved randomization to one of three sleep doses (4 h, 6 h, or 8 h time in bed per night), which were maintained for 14 consecutive days. The total sleep deprivation experiment involved 3 nights without sleep (0 h time in bed). Each study also involved 3 baseline (pre-deprivation) days and 3 recovery days. SETTING: Both experiments were conducted under standardized laboratory conditions with continuous behavioral, physiological and medical monitoring. PARTICIPANTS: A total of n = 48 healthy adults (ages 21-38) participated in the experiments. INTERVENTIONS: Noctumal sleep periods were restricted to 8 h, 6 h or 4 h per day for 14 days, or to 0 h for 3 days. All other sleep was prohibited. RESULTS: Chronic restriction of sleep periods to 4 h or 6 h per night over 14 consecutive days resulted in significant cumulative, dose-dependent deficits in cognitive performance on all tasks. Subjective sleepiness ratings showed an acute response to sleep restriction but only small further increases on subsequent days, and did not significantly differentiate the 6 h and 4 h conditions. Polysomnographic variables and delta power in the non-REM sleep EEG-a putative marker of sleep homeostasis--displayed an acute response to sleep restriction with negligible further changes across the 14 restricted nights. Comparison of chronic sleep restriction to total sleep deprivation showed that the latter resulted in disproportionately large waking neurobehavioral and sleep delta power responses relative to how much sleep was lost. A statistical model revealed that, regardless of the mode of sleep deprivation, lapses in behavioral alertness were near-linearly related to the cumulative duration of wakefulness in excess of 15.84 h (s.e. 0.73 h). CONCLUSIONS: Since chronic restriction of sleep to 6 h or less per night produced cognitive performance deficits equivalent to up to 2 nights of total sleep deprivation, it appears that even relatively moderate sleep restriction can seriously impair waking neurobehavioral functions in healthy adults. Sleepiness ratings suggest that subjects were largely unaware of these increasing cognitive deficits, which may explain why the impact of chronic sleep restriction on waking cognitive functions is often assumed to be benign. Physiological sleep responses to chronic restriction did not mirror waking neurobehavioral responses, but cumulative wakefulness in excess of a 15.84 h predicted performance lapses across all four experimental conditions. This suggests that sleep debt is perhaps best understood as resulting in additional wakefulness that has a neurobiological \"cost\" which accumulates over time.", "title": "The cumulative cost of additional wakefulness: dose-response effects on neurobehavioral functions and sleep physiology from chronic sleep restricti..." }, { "docid": "MED-2325", "text": "Restriction of food intake by 10-50% of ad libitum on a per unit of weight or energy content basis can extend the lifespan of a wide variety of species and prevent or delay age-related disease.

METHODS: In experiment 1, each of 4 groups with 10 adult rats was assigned to a high-carb diet (AIN-93G) + ad libitum intake or restricted feeding, or a low-carb diet (53% horsemeat) + ad libitum intake or restricted feeding (2 x 2 factorial).

Review of the literature was undertaken to determine whether there is evidence that whole organism aging and cell senescence share a common initiation pathway. In vivo aged cells of different lineages, including aged T lymphocytes, show high expression of the INK4A-p16 gene. In cell culture when telomeres are shortened past a key length or state, the Arf/Ink gene system (p16/p14 humans, p16/p19 mice) switches on and activates p53, which suppresses further cell division. The p53 gene is a key tumor suppressor and its deletion or mutation allows cancerous growth. The switching on of p53 also causes changes in fatty acid metabolism, especially down-regulation of both fatty acid synthase and stearoyl-CoA (delta-9) desaturase. The co-suppression of these genes together with enhanced uptake of extracellular fatty acids, leads to raised levels of cellular palmitate and induction of either apoptosis or senescence. In senescent cells, the fatty acid composition of the cellular membranes alters and leads to changes in both structure and function of organelles, especially mitochondria. Animal models of accelerated aging exhibit repression of stearoyl-CoA desaturase activity while anti-aging calorie restriction stimulates the same enzyme system. It is concluded that aging in cells and whole organisms share a common initiation pathway and that cellular senescence is protective against cancer.

While investing in individual stocks can be very useful as a learning experience, my opinion is that concentrating an entire portfolio in a few companies' stock is a mistake for most investors, and especially for a novice for several reasons. After all, only a handful of professional investors have ever beaten the market over the long term by picking stocks, so is it really worth trying? If you could, I'd say go work on Wall Street and good luck to you. Diversification For many investors, diversification is an important reason to use an ETF or index fund. If they were to focus on a few sectors or companies, it is more likely that they would have a lop-sided risk profile and might be subject to a larger downside risk potential than the market as a whole, i.e. \"\"don't put all your eggs in one basket\"\". Diversification is important because of the nature of compound investing - if you take a significant hit, it will take you a long time to recover because all of your future gains are building off of a smaller base. This is one reason that younger investors often take a larger position in equities, as they have longer to recover from significant market declines. While it is very possible to build a balanced, diversified portfolio from individual stocks, this isn't something I'd recommend for a new investor and would require a substantial college-level understanding of investments, and in any case, this portfolio would have a more discrete efficient frontier than the market as a whole. Lower Volatility Picking individual stocks or sectors would could also significantly increase or decrease the overall volatility of the portfolio relative to the market, especially if the stocks are highly cyclical or correlated to the same market factors. So if they are buying tech stocks, they might see bigger upswings and downswings compared to the market as a whole, or see the opposite effect in the case of utilities. In other words, owning a basket of individual stocks may result in an unintended volatility/beta profile. Lower Trading Costs and Taxes Investors who buy individual stocks tend to trade more in an attempt to beat the market. After accounting for commission fees, transaction costs (bid/ask spread), and taxes, most individual investors get only a fraction of the market average return. One famous academic study finds that investors who trade more trail the stock market more. Trading also tends to incur higher taxes since short term gains (<1 year) are taxed at marginal income tax rates that are higher than long term capital gains. Investors tend to trade due to behavioral failures such as trying to time the market, being overconfident, speculating on stocks instead of long-term investing, following what everyone else is doing, and getting in and out of the market as a result of an emotional reaction to volatility (ie buying when stocks are high/rising and selling when they are low/falling). Investing in index funds can involve minimal fees and discourages behavior that causes investors to incur excessive trading costs. This can make a big difference over the long run as extra costs and taxes compound significantly over time. It's Hard to Beat the Market since Markets are Quite Efficient Another reason to use funds is that it is reasonable to assume that at any point in time, the market does a fairly good job of pricing securities based on all known information. In other words, if a given stock is trading at a low P/E relative to the market, the market as a whole has decided that there is good reason for this valuation. This idea is based on the assumption that there are already so many professional analysts and traders looking for arbitrage opportunities that few such opportunities exist, and where they do exist, persist for only a short time. If you accept this theory generally (obviously, the market is not perfect), there is very little in the way of insight on pricing that the average novice investor could provide given limited knowledge of the markets and only a few hours of research. It might be more likely that opportunities identified by the novice would reflect omissions of relevant information. Trying to make money in this way then becomes a bet that other informed, professional investors are wrong and you are right (options traders, for example). Prices are Unpredictable (Behave Like \"\"Random\"\" Walks) If you want to make money as a long-term investor/owner rather than a speculator/trader, than most of the future change in asset prices will be a result of future events and information that is not yet known. Since no one knows how the world will change or who will be tomorrow's winners or losers, much less in 30 years, this is sometimes referred to as a \"\"random walk.\"\" You can point to fundamental analysis and say \"\"X company has great free cash flow, so I will invest in them\"\", but ultimately, the problem with this type of analysis is that everyone else has already done it too. For example, Warren Buffett famously already knows the price at which he'd buy every company he's interested in buying. When everyone else can do the same analysis as you, the price already reflects the market's take on that public information (Efficent Market theory), and what is left is the unknown (I wouldn't use the term \"\"random\"\"). Overall, I think there is simply a very large potential for an individual investor to make a few mistakes with individual stocks over 20+ years that will really cost a lot, and I think most investors want a balance of risk and return versus the largest possible return, and don't have an interest in developing a professional knowledge of stocks. I think a better strategy for most investors is to share in the future profits of companies buy holding a well-diversified portfolio for the long term and to avoid making a large number of decisions about which stocks to own.\"", "title": "" }, { "docid": "493671", "text": "\"i'm absolutely a newcomer in economics and i wish to understand how things work around finance. This is a pretty loaded question. To understand finance, you need the basics of economics. In almost every economics school in the country, you first study microeconomics and then economics. So, we'll start with micro. One of, if not the, most popular books is \"\"Principles of Microeconomics\"\" by Mankiw. This book covers the fundamentals of micro econ (opportunity, supply, demand, consumer choice, production, costs, basic game theory, and allocation of resources) in a clear and effective manner. It's designed for the novice and very easy to read. Like Mankiw's other book, \"\"Principles of Macroeconomics\"\" is also top notch. There is some overlap in key areas (i.e. opportunity cost, supply, demand, indifference curves, elasticity, taxation) because they are fundamental to economics and the overlap will always be there, but from there the book goes into key macro concepts like GDP, CPI, Employment, Monetary and Fiscal policy, and Inflation. An excellent intro primer indeed. Now that you have the fundamentals down, it's time to learn about finance. The best resource, in my opinion, is \"\"Financial Markets\"\" by Robert Shiller on Open Yale Courses. I've personally taken Prof. Shiller's class last semester, and the man is brilliant. The lectures cover every single aspect of finance and can turn the complete novice into a fairly experienced finance student. The first lecture also covers all the math required so you don't get lost at any point. Be warned, however, that the course is very deep. We used Fabozzi's textbook \"\"Foundations of Financial Markets and Institutions,\"\" which is over 600 pages deep and we were required to know essentially all of it. Watch the videos and follow the readings and you'll be a finance whiz soon! Financial Markets on Open Yale And that's your roadmap to what you want. There are other economics books and it's true that the first few chapters of both Mankiw books are largely the same, but that's because any economics course always covers the basics first. If you want to look at other books, Krugman has written some good books as well. Be sure to read reviews because some books are meant for 2nd/3rd year econ students, so you don't want to get a too advanced book. At the novice level, we're interested in understanding the basic concepts so we can master Fabozzi. As for finance books - Fabozzi teaches you all the fundamentals of financial markets so you've got a powerful foundation. From there you can expand to more niche books such as books on investing or on monetary policy or whatever you want.

For example, you could open a Roth IRA account with Vanguard. You could then invest the $3000 by purchasing shares of VOO, which tracks the S&P 500 index and has a very low expense ratio (0.04 as of last time I checked). Fidelity has a similar option, or Schwab, or whatever brokerage firm you prefer. IRAs are basically just normal investment accounts, except they don't owe taxes until you withdraw them (and Roth don't even owe them then, though you paid taxes on the funds you deposit). They have some limitations regarding options trading and such, but if you're a novice investor just looking to do basic investments, you'll not notice. Then, your IRA would go up or down in value as the market went up or down in value. You do have some restrictions on when you can withdraw the funds; Roth IRA has fewer than a normal IRA, as you can withdraw the capital (the amount you deposited) without penalty, but the profits cannot be withdrawn until you're retirement age (I won't put an actual year, as I suspect that actual year will change by the time you're that old; but think 60s). The reason not to invest in an IRA is if you plan on using the money in the near future - even as an \"\"emergency fund\"\". You should have some money that is not invested aggressively, that is in something very safe and very accessible, for your emergency fund; and if you plan to buy a house or whatever with the funds, don't start an IRA.

In fact, there is no investment that is safe for an absolute beginner, not even a savings account. (An absolute beginner could easily overdraw his savings account, leading to fees and collections.) I would say that an investment becomes a good fit for an investor as soon as said investor understands how the investment works. A savings account at a bank or credit union is fairly easy to understand and is therefore a suitable place to hold money after a few hours to a day of research. (Even after 0 hours of research, however, a savings account is still better than a sock drawer.) Money market accounts (through a bank), certificates of deposit (through a bank), and money market mutual funds (through a mutual fund provider) are probably the next easiest thing to understand. This could take a few hours to a few weeks of research depending on the learner. Equities, corporate bonds, and government bonds are another step up in complexity, and could take weeks or months of schooling to understand well enough to try. Equity or bond mutual funds -- or the ETF versions of those, which is what you asked about -- are another level after that. Also important to understand along the way are the financial institutions and market infrastructure that exist to provide these products: banks, credit unions, public corporations, brokerages, stock exchanges, bond exchanges, mutual fund providers, ETF providers, etc.", "title": "" }, { "docid": "169004", "text": "Basically there are 2 ways you can make money from an investment, through income (eg: rent or dividends) and through the price of the investment going up (capital growth or gains). Most people associate negative gearing with investment properties but it can be done with shares and other investments where you borrow money to buy the investment and it produces an income of some sort. If the investment does not produce an income then you cannot negative gear it. Using a property as an example (in Australia), if all your expenses each month (loan interest payments, council and water rates, insurance and/or strata, advertising and management fees, depreciation, and maintenance expense) are greater than your income (rent), then you are negative gearing the investment property. This is a monthly loss on your investment which can be used to offset and reduce the amount of tax you pay during the year. So most people negative gearing an investment property will get a nice sum back when they do their tax returns. The problem with negative gearing is that you have to lose money in order to save some tax. So as an example, if you are on a marginal tax rate of 30%, for every $1 you lose from the investment property you will save 30c in tax. If your marginal tax rate is 45% then will save 45c in tax for every $1 lost on the investment property. Thus negative gearing becomes more tax effective the higher your income (and tax bracket). But you are still losing money overall. The problem is that most novice investors buy an investment property for the main purpose of reducing their taxes. This can be dangerous because the main reason to buy any investment should be that you consider it to be a good investment, not to save you tax. Because if the investment is not a good one, then you will not only lose money on the income side but also on the capital side. Negative gearing should be looked at as a bonus or additional benefit when chosing a good investment to buy, not as the reason to buy the investment.", "title": "" }, { "docid": "379546", "text": "It sounds like you are interested in investing in the stock market but you don't want to take too much risk.

Stock always carries large risks (~50% swings in capital are pretty standard in the short run. In the long run it generally beats every other asset class by miles). If you can’t handle those types of short terms swings, you shouldn’t get involved. If you do want to invest in stock, there is a hefty ignorance tax waiting at every corner in terms of how brokers construct their fees. In a nutshell, there is a different best value broker in the UK for virtually every band of capital, and they make their money through people signing up when they are in range x, and not moving their money when they reach band y; or just having a large marketing budget and screwing you from the start (Nutmeg at ~1% a year is def in this category). There isn't much of an obvious way around this if you are adamant you don't want to learn about it - the way the market is constructed is just a total predatory minefield for the complete novice. There are middle ground style investments between the two extremes you are looking at: bonds, bond funds and mixes of bonds and small amounts of stock (such as the Vanguard income or Conservative Growth funds outlined here), can return more than savings accounts with less risk than stocks, but again its a very diverse field that's hard to give specific advice about without knowing more about what your risk tolerance, timelines and aims are.

If you are relying on rental properties for current income versus a long term return you are going to have to do a good job at shopping for bargains to get monthly cash flow versus equity growth that is locked up in the property until you sell it. If you want to pull a lot of cash out of a property on a regular basis you probably are going to have to get into flipping them, which is decidedly not passive investing. Also, it is easy to underestimate the expenses associated with rental properties. Texas is pretty landlord friendly legally, however it does have higher than usual property taxes, which will eat into your return. Also, you need to factor in maintenance, vacancy, tenant turnover costs, etc. It can add up to a lot more than you would expect. If you are handy and can do a lot of repairs yourself you can increase your return, but that makes it less of a passive investment. The two most common rules I have heard for initially evaluating whether an investment property is likely to be cash flow positive are the 1% and 50% rules. The 1% rule says the expected monthly rent needs to be 1% or greater of the purchase price of the house. So your hypothetical $150K/$10K scenario doesn't pass that test. Some people say this rule is 2% for new landlords, but in my experience you'd have to get lucky in Texas to find a house priced that competitively that didn't need a lot of work to get rents that high. The 50% rule says that the rent needs to be double your mortgage payment to account for expenses.

I for example, do not understand stocks, and so do not seriously work the stock market. Mutual funds make money for the folks selling them whether or not the price goes up or down. You assume all the risk while the mutual fund advisor gets the reward. If you find a mutual fund advisor who cannot recommend the purchase of a product he doesn't sell, he's not an advisor, he's a salesman. Investing in business requires you either to intimately understand businesses and how to fund them, or to hire someone who can make an objective evaluation for you. Again this requires training. I have no such training, and avoid investing in businesses. Investing in real estate also requires you to know what to look for in a property that produces cash flow or capital gains. I took a course, read some books, gained experience and have a knowledgeable team at my disposal so my wins are greater than my losses. Do not be fooled by people telling you that higher risk means higher reward. Risks that you understand and have a detailed plan to mitigate are not risks. It is possible to have higher reward without increasing risk. Again, do your own research. The richest people in the world do not own mutual funds or IRAs or RRSPs or TFSAs, they do their own research and invest in the things I mentioned above.\"", "title": "" }, { "docid": "129255", "text": "Investing is really about learning your own comfort level. You will make money and lose money. You will make mistakes but you will also learn a great deal. First off, invest in your own financial knowledge, this doesn't require capital at all but a commitment. No one will watch or care for your own money better than yourself. Read books, and follow some companies in a Google Finance virtual portfolio. Track how they're doing over time - you can do this as a virtual portfolio without actually spending or losing money. Have you ever invested before? What is your knowledge level? Investing long term is about trying to balance risk while reducing losses and trying not to get screwed along the way (by people). My personal advice: Go to an independent financial planner, go to one that charges you per hour only. Financial planners that don't charge you hourly get paid in commissions. They will be biased to sell you what puts the most money in their pockets. Do not go to the banks investment people, they are employed by the banks who have sales and quota requirements to have you invest and push their own investment vehicles like mutual funds. Take $15k to the financial planner and see what they suggest. Keep the other $5K in something slow and boring and $1k under your mattress in actual cash as an emergency. While you're young, compound interest is the magic that will make that $25k increase hand over fist in time. But you need to have it consistently make money. I'm young too and more risk tolerant because I have time. While I get older I can start to scale back my risk because I'm nearing retirement and preserve instead of try to make returns.", "title": "" }, { "docid": "136307", "text": "I like to put money I am going to spend in my Quicken register (similar to Money in my limited experience) and that is the big ticket feature missing from mint.com.

I'm not sure how to find a firm that you like the investment strategy of. I think that it's too complicated to do as a side thing. Someone needs to be spending a lot of time researching various instruments and figuring out what is undervalued or what is exposed to changing market trends or whatever. I basically just want to give my money to someone and say \"\"I agree with your investment philosophy, let me pay you to manage my money, too.\"\" No one knows who is right, of course. I think Schiff is right, so that's where I would put the amount of money you're talking about. If you disagree with his investment philosophy, this doesn't really make any sense to do. For that amount of money, though, I think firms would be willing to sit down with you and sell you their services. You could ask them how they would diversify this money given the goals that you have for it, and pick one that you agree with the most.\"", "title": "" }, { "docid": "582161", "text": "\"As others have pointed out, leveraged investing is investing borrowed money. To do so, you need to convince a lender that you're good for the loan. This usually means you need to have collateral worth what you're trying to borrow, or you need to pay a higher rate to account for the fact that they're gambling that you will remain employed and pay off the loan. Leveraged investing is, in general, a risky move for exactly this reason. You can lose not just your original investment, but everything you borrowed as well. The only time it really makes sense, in my admittedly conservative opinion, is when you (a) can afford to suffer that loss, (b) are pretty confident of your investment, and (c) have assets which you have no intention to sell for the duration of the loan. An \"\"unneeded\"\" mortgage on a house is a classic example, thusly: When I purchased my house, I had enough savings that I could have bought it without taking a mortgage. Instead, I took out a mortgage for a large part of that, and left the remainder in my investment accounts -- essentially building the leveraging loan into the mortgage. I then got obscenely \"\"lucky\"\" when interest rates fell through the floor due to the Great Recession, and was able to refinance the mortgage to near record low rates. As a result, on that loan -- which, as I say, I'm in the position of being able to pay off at any time without killing my finances -- I'm currently paying about 3.5%, while the cash this has let me leave in my investments is earning several times that... a net win. But again, note that this required collateral. Essentially, all I'm doing is paying a bit to to borrow my own money (part of the value of the house). There really is no easy way to \"\"convert 25k to 250k\"\" -- if there was, everyone would be doing it. There's no magic in investment. Just time and compounding returns and trading off risk against potential gain. The more you try to push it and win big, the more you risk losing big. I really recommend not attempting anything fancy until you're wealthy enough that you can afford those losses. But if you insist on playing in this space, the answer to your question is to buy options. Options are a packaged form of borrowing to invest. Note that they're still considered high-risk unless you know EXACTLY what you're doing, and again I strongly recommend you not put money into them unless you can afford to lose it -- options have a nasty habit of turning from apparent gains on paper to losses remarkably quickly.\"", "title": "" }, { "docid": "473949", "text": "\"Many of my friends said I should invest my money on stocks or something else, instead of put them in the bank forever. I do not know anything about finance, so my questions are: First let me say that your friends may have the best intentions, but don't trust them. It has been my experience that friends tell you what they would do if they had your money, and not what they would actually do with their money. Now, I don't mean that they would be malicious, or that they are out to get you. What I do mean, is why would you take advise from someone about what they would do with 100k when they don't have 100k. I am in your financial situation (more or less), and I have friends that make more then I do, and have no savings. Or that will tell you to get an IRA -so-and-so but don't have the means (discipline) to do so. Do not listen to your friends on matters of money. That's just good all around advise. Is my financial status OK? If not, how can I improve it? Any financial situation with no or really low debt is OK. I would say 5% of annual income in unsecured debt, or 2-3 years in annual income in secured debt is a good place to be. That is a really hard mark to hit (it seems). You have hit it. So your good, right now. You may want to \"\"plan for the future\"\". Immediate goals that I always tell people, are 6 months of income stuck in a liquid savings account, then start building a solid investment situation, and a decent retirement plan. This protects you from short term situations like loss of job, while doing something for the future. Is now a right time for me to see a financial advisor? Is it worthy? How would she/he help me? Rather it's worth it or not to use a financial adviser is going to be totally opinion based. Personally I think they are worth it. Others do not. I see it like this. Unless you want to spend all your time looking up money stuff, the adviser is going to have a better grasp of \"\"money stuff\"\" then you, because they do spend all their time doing it. That being said there is one really important thing to consider. That is going to be how you pay the adviser. The following are my observations. You will need to make up your own mind. Free Avoid like the plague. These advisers are usually provided by the bank and make their money off commission or kickbacks. That means they will advise you of the product that makes them the most money. Not you. Flat Rate These are not a bad option, but they don't have any real incentive to make you money. Usually, they do a decent job of making you money, but again, it's usually better for them to advise you on products that make them money. Per Hour These are my favorite. They charge per hour. Usually they are a small shop, and will walk you through all the advise. They advise what's best for you, because they have to sit there and explain their choices. They can be hard to find, but are generally the best option in my opinion. % of Money These are like the flat rate advisers to me. They get a percentage of the money you give them to \"\"manage\"\". Because they already have your money they are more likely to recommend products that are in their interest. That said, there not all bad. % or Profit These are the best (see notes later). They get a percentage of the money they make for you. They have the most interest in making you money. They only get part of what you get, so there going to make sure you get the biggest pie, so they can get a bigger slice. Notes In the real world, all advisers are likely to get kickbacks on products they recommend. Make sure to keep an eye for that. Also most advisers will use 2-3 of the methods listed above for billing. Something like z% of profit +$x per hour is what I like to see. You will have to look around and see what is available. Just remember that you are paying someone to make you money (or to advise you on how to make money) so long as what they take leaves you with some profit your in a better situation then your are now. And that's the real goal.\"", "title": "" }, { "docid": "47973", "text": "\"First, I applaud you for caring. Most people don't! In fact, I was in that category. You bring up several issues and I'll try to address them separately. (1) Getting a financial planner to talk with you. I had the same experience! My belief is that they don't want to admit that they don't know how things work. I even asked if I could pay them an hourly fee to ask questions and review stocks with them. Most declined. You'll find that very few people actually take the time to get trained to evaluate stocks and the stock market as a whole. (See later Investools.com). After looking, however, I did find people who would spend an hour or two with me when we met once a quarter to review my \"\"portfolio\"\"/investments. I later found training that companies offered. I would attend any free training I could get because they actually wanted to spend time and talk and teach investors. Bottom line is: Talking to their clients is the job of a financial planner. If he (or she) is not willing to take this time, it is in your best interest to find someone who will spend that time. (2) Learning about investing! I'm not affiliated with anyone. I'm a software developer and I do my own trading/investments. The opinions I share are my own. When I was 20 years away from retirement, I started learning about the stock market so that I would know how it worked before I retired so that (a) I could influence a change if one was needed, and (b) so I wouldn't have to blindly accept the advice of the \"\"experts\"\" even when the stock market is crashing. I have used Investools.com, and TDAmeritrade's Think-or-Swim platform. I've learned a tremendous amount from the Investools training. I recommend them. But don't expect to learn how to get rich from them or any training you take. The TDA Think-or-swim platform I highly recommend BECAUSE it has a feature called \"\"Paper Money\"\". It lets you trade using the real market but with play money. I highly recommend ANY platform that you can use to trade IN PAPER money! The think-or-swim platform would allow you to invest $30,000 in paper money (you can have as much as you want) into any stock. This would let you see if you can make more money than your current investment advisor. You could invest $10K in one SPY, $10K in DIA and $10K in IWM (these are symbols for the S&P 500, Dow 30, and Small Cap stocks). This is just an example, I'm not suggesting any investment advise! It's important that you actually do this not just write down on a piece of paper or Excel spreadsheet what you were going to do because it's common to \"\"cheat\"\" and change the dates to meet your needs. I have found it incredibly helpful to understand how the market works by trying to do my own paper and now real money investing. I was and you will be surprised to find that many trades lose money during the initial start part of the trade because it's very difficult to buy at the exact right time. An important part of managing your own investments is learning to trade with rules and not get \"\"emotionally involved\"\" in your trades. (3) Return on investment. You were not happy with $12 return. Low returns are a byproduct of the way most investment firms (financial planners) take (diversification). They diversify to take a \"\"hands off\"\" approach toward investment because that approach has been the only approach that they have found that works relatively well in all market conditions. It's not (necessarily) a bad approach. It avoids large losses in down markets (most riskier approaches lose more than the market). The downside is it also avoids the high returns. If the market goes up 15% the investment might only go up 5%. 30K is enough to give to multiple investment firms a try. I gave two different firms $25K each to see how they would invest. The direction was to accept LOTS of risk (with the potential for large losses or large gains). In a year that the market did very well, one lost money, and one made a small gain. It was a learning experience. I, now, have taken the money back and invest it myself. NOTE: I would be happy with a guy who made me 10-15% year over year (in good times and bad) and didn't talk with me, but I haven't found someone who can do that. :-) NOTE 2: Don't believe what you hear from the news about the stock market being up 5% year to date. Do your own analysis. NOTE 3: Investing in \"\"the market\"\" (S&P 500 for example) is a great way to go if you're just starting. Few investment firms can beat \"\"the market\"\" although many try to do so. I too have found it's easier to do that than other approaches I've learned. So, it might be a good long term approach as well. Best wishes to you in your learning about the market and desires to make money with your money. That is what is all about.\"", "title": "" } ]

However, estimates from claims data may lack clinical fidelity and can be affected by changing diagnosis and coding practices over time. Objective To estimate the US national incidence of sepsis and trends using detailed clinical data from the electronic health record (EHR) systems of diverse hospitals. Design, Setting, and Population Retrospective cohort study of adult patients admitted to 409 academic, community, and federal hospitals from 2009-2014. Exposures Sepsis was identified using clinical indicators of presumed infection and concurrent acute organ dysfunction, adapting Third International Consensus Definitions for Sepsis and Septic Shock (Sepsis-3) criteria for objective and consistent EHR-based surveillance. Main Outcomes and Measures Sepsis incidence, outcomes, and trends from 2009-2014 were calculated using regression models and compared with claims-based estimates using International Classification of Diseases, Ninth Revision, Clinical Modification codes for severe sepsis or septic shock. Case-finding criteria were validated against Sepsis-3 criteria using medical record reviews. Results A total of 173 690 sepsis cases (mean age, 66.5 [SD, 15.5] y; 77 660 [42.4%] women) were identified using clinical criteria among 2 901 019 adults admitted to study hospitals in 2014 (6.0% incidence). Of these, 26 061 (15.0%) died in the hospital and 10 731 (6.2%) were discharged to hospice. From 2009-2014, sepsis incidence using clinical criteria was stable (+0.6% relative change/y [95% CI, −2.3% to 3.5%], P = .67) whereas incidence per claims increased (+10.3%/y [95% CI, 7.2% to 13.3%], P < .001). In-hospital mortality using clinical criteria declined (−3.3%/y [95% CI, −5.6% to −1.0%], P = .004), but there was no significant change in the combined outcome of death or discharge to hospice (−1.3%/y [95% CI, −3.2% to 0.6%], P = .19). In contrast, mortality using claims declined significantly (−7.0%/y [95% CI, −8.8% to −5.2%], P < .001), as did death or discharge to hospice (−4.5%/y [95% CI, −6.1% to −2.8%], P < .001). Clinical criteria were more sensitive in identifying sepsis than claims (69.7% [95% CI, 52.9% to 92.0%] vs 32.3% [95% CI, 24.4% to 43.0%], P < .001), with comparable positive predictive value (70.4% [95% CI, 64.0% to 76.8%] vs 75.2% [95% CI, 69.8% to 80.6%], P = .23). Conclusions and Relevance In clinical data from 409 hospitals, sepsis was present in 6% of adult hospitalizations, and in contrast to claims-based analyses, neither the incidence of sepsis nor the combined outcome of death or discharge to hospice changed significantly between 2009-2014.

[ { "docid": "5596332", "text": "IMPORTANCE Definitions of sepsis and septic shock were last revised in 2001. Considerable advances have since been made into the pathobiology (changes in organ function, morphology, cell biology, biochemistry, immunology, and circulation), management, and epidemiology of sepsis, suggesting the need for reexamination. OBJECTIVE To evaluate and, as needed, update definitions for sepsis and septic shock. PROCESS A task force (n = 19) with expertise in sepsis pathobiology, clinical trials, and epidemiology was convened by the Society of Critical Care Medicine and the European Society of Intensive Care Medicine. Definitions and clinical criteria were generated through meetings, Delphi processes, analysis of electronic health record databases, and voting, followed by circulation to international professional societies, requesting peer review and endorsement (by 31 societies listed in the Acknowledgment). KEY FINDINGS FROM EVIDENCE SYNTHESIS Limitations of previous definitions included an excessive focus on inflammation, the misleading model that sepsis follows a continuum through severe sepsis to shock, and inadequate specificity and sensitivity of the systemic inflammatory response syndrome (SIRS) criteria. Multiple definitions and terminologies are currently in use for sepsis, septic shock, and organ dysfunction, leading to discrepancies in reported incidence and observed mortality. The task force concluded the term severe sepsis was redundant. RECOMMENDATIONS Sepsis should be defined as life-threatening organ dysfunction caused by a dysregulated host response to infection. For clinical operationalization, organ dysfunction can be represented by an increase in the Sequential [Sepsis-related] Organ Failure Assessment (SOFA) score of 2 points or more, which is associated with an in-hospital mortality greater than 10%. Septic shock should be defined as a subset of sepsis in which particularly profound circulatory, cellular, and metabolic abnormalities are associated with a greater risk of mortality than with sepsis alone. Patients with septic shock can be clinically identified by a vasopressor requirement to maintain a mean arterial pressure of 65 mm Hg or greater and serum lactate level greater than 2 mmol/L (>18 mg/dL) in the absence of hypovolemia. This combination is associated with hospital mortality rates greater than 40%. In out-of-hospital, emergency department, or general hospital ward settings, adult patients with suspected infection can be rapidly identified as being more likely to have poor outcomes typical of sepsis if they have at least 2 of the following clinical criteria that together constitute a new bedside clinical score termed quickSOFA (qSOFA): respiratory rate of 22/min or greater, altered mentation, or systolic blood pressure of 100 mm Hg or less. CONCLUSIONS AND RELEVANCE These updated definitions and clinical criteria should replace previous definitions, offer greater consistency for epidemiologic studies and clinical trials, and facilitate earlier recognition and more timely management of patients with sepsis or at risk of developing sepsis.", "title": "The Third International Consensus Definitions for Sepsis and Septic Shock (Sepsis-3)." }, { "docid": "26314743", "text": "BACKGROUND: A proposed revision of sepsis definitions has abandoned the systemic inflammatory response syndrome (SIRS), defined organ dysfunction as an increase in total Sequential Organ Function Assessment (SOFA) score of ≥ 2, and conceived “qSOFA” (quick SOFA) as a bedside indicator of organ dysfunction. We aimed to (1) determine the prognostic impact of SIRS, (2) compare the diagnostic accuracy of SIRS and qSOFA for organ dysfunction, and (3) compare standard (Sepsis‐2) and revised (Sepsis‐3) definitions for organ dysfunction in ED patients with infection. METHODS: Consecutive ED patients admitted with presumed infection were prospectively enrolled over 3 years. Sufficient observational data were collected to calculate SIRS, qSOFA, SOFA, comorbidity, and mortality. RESULTS: We enrolled 8,871 patients, with SIRS present in 4,176 (47.1%). SIRS was associated with increased risk of organ dysfunction (relative risk [RR] 3.5) and mortality in patients without organ dysfunction (OR 3.2). SIRS and qSOFA showed similar discrimination for organ dysfunction (area under the receiver operating characteristic curve, 0.72 vs 0.73). qSOFA was specific but poorly sensitive for organ dysfunction (96.1% and 29.7%, respectively). Mortality for patients with organ dysfunction was similar for Sepsis‐2 and Sepsis‐3 (12.5% and 11.4%, respectively), although 29% of patients with Sepsis‐3 organ dysfunction did not meet Sepsis‐2 criteria. Increasing numbers of Sepsis‐2 organ system dysfunctions were associated with greater mortality. CONCLUSIONS: SIRS was associated with organ dysfunction and mortality, and abandoning the concept appears premature. A qSOFA score ≥ 2 showed high specificity, but poor sensitivity may limit utility as a bedside screening method. Although mortality for organ dysfunction was comparable between Sepsis‐2 and Sepsis‐3, more prognostic and clinical information is conveyed using Sepsis‐2 regarding number and type of organ dysfunctions.

Neonatal mortality (deaths <28 days of age) has received limited attention, although such deaths account for about 41% of all child deaths. To better assess progress, we developed annual estimates for neonatal mortality rates (NMRs) and neonatal deaths for 193 countries for the period 1990-2009 with forecasts into the future. METHODS AND FINDINGS We compiled a database of mortality in neonates and children (<5 years) comprising 3,551 country-years of information. Reliable civil registration data from 1990 to 2009 were available for 38 countries. A statistical model was developed to estimate NMRs for the remaining 155 countries, 17 of which had no national data. Country consultation was undertaken to identify data inputs and review estimates. In 2009, an estimated 3.3 million babies died in the first month of life-compared with 4.6 million neonatal deaths in 1990-and more than half of all neonatal deaths occurred in five countries of the world (44% of global livebirths): India 27.8% (19.6% of global livebirths), Nigeria 7.2% (4.5%), Pakistan 6.9% (4.0%), China 6.4% (13.4%), and Democratic Republic of the Congo 4.6% (2.1%). Between 1990 and 2009, the global NMR declined by 28% from 33.2 deaths per 1,000 livebirths to 23.9. The proportion of child deaths that are in the neonatal period increased in all regions of the world, and globally is now 41%. While NMRs were halved in some regions of the world, Africa's NMR only dropped 17.6% (43.6 to 35.9). CONCLUSIONS Neonatal mortality has declined in all world regions. Progress has been slowest in the regions with high NMRs.

We therefore compared the sepsis populations identified by the old and new definitions. Methods We used a high-quality, national, intensive care unit (ICU) database of 654 918 consecutive admissions to 189 adult ICUs in England, from January 2011 to December 2015. Primary outcome was acute hospital mortality. We compared old (Sepsis-2) and new (Sepsis-3) incidence, outcomes, trends in outcomes, and predictive validity of sepsis and septic shock populations. Results From among 197 724 Sepsis-2 severe sepsis and 197 142 Sepsis-3 sepsis cases, we identified 153 257 Sepsis-2 septic shock and 39 262 Sepsis-3 septic shock cases. The extrapolated population incidence of Sepsis-3 sepsis and Sepsis-3 septic shock was 101.8 and 19.3 per 100 000 person-years, respectively, in 2015. Sepsis-2 severe sepsis and Sepsis-3 sepsis had similar incidence, similar mortality and showed significant risk-adjusted improvements in mortality over time. Sepsis-3 septic shock had a much higher Acute Physiology And Chronic Health Evaluation II (APACHE II) score, greater mortality and no risk-adjusted trends in mortality improvement compared with Sepsis-2 septic shock. ICU admissions identified either as Sepsis-3 sepsis or septic shock and as Sepsis-2 severe sepsis or septic shock had significantly greater risk-adjusted odds of death compared with non-sepsis admissions (P<0.001). The predictive validity was greatest for Sepsis-3 septic shock. Conclusions In an ICU database, compared with Sepsis-2, Sepsis-3 identifies a similar sepsis population with 92% overlap and much smaller septic shock population with improved predictive validity.", "title": "Epidemiology of sepsis and septic shock in critical care units: comparison between sepsis-2 and sepsis-3 populations using a national critical care database" }, { "docid": "5185871", "text": "Importance The Sepsis-3 Criteria emphasized the value of a change of 2 or more points in the Sequential [Sepsis-related] Organ Failure Assessment (SOFA) score, introduced quick SOFA (qSOFA), and removed the systemic inflammatory response syndrome (SIRS) criteria from the sepsis definition. Objective Externally validate and assess the discriminatory capacities of an increase in SOFA score by 2 or more points, 2 or more SIRS criteria, or a qSOFA score of 2 or more points for outcomes among patients who are critically ill with suspected infection. Design, Setting, and Participants Retrospective cohort analysis of 184 875 patients with an infection-related primary admission diagnosis in 182 Australian and New Zealand intensive care units (ICUs) from 2000 through 2015. Exposures SOFA, qSOFA, and SIRS criteria applied to data collected within 24 hours of ICU admission. Main Outcomes and Measures The primary outcome was in-hospital mortality. In-hospital mortality or ICU length of stay (LOS) of 3 days or more was a composite secondary outcome. Discrimination was assessed using the area under the receiver operating characteristic curve (AUROC). Adjusted analyses were performed using a model of baseline risk determined using variables independent of the scoring systems. Results Among 184 875 patients (mean age, 62.9 years [SD, 17.4]; women, 82 540 [44.6%]; most common diagnosis bacterial pneumonia, 32 634 [17.7%]), a total of 34 578 patients (18.7%) died in the hospital, and 102 976 patients (55.7%) died or experienced an ICU LOS of 3 days or more.

We investigated how cell wall components of gram-positive bacteria contribute to the development of sepsis. Experimental observations derived from cultured primary macrophages and the cell line indicate that gram-positive bacterial endotoxins induce hypoxia-inducible factor 1α (HIF-1α) mRNA and protein expression. Inoculation of live or heat-inactivated gram-positive bacteria with macrophages induced HIF-1 transcriptional activity in macrophages. Concordant with these results, myeloid deficiency of HIF-1α attenuated gram-positive bacterial endotoxin-induced cellular motility and proinflammatory gene expression in macrophages. Conversely, gram-positive bacteria and their endotoxins reduced expression of the myeloid anti-inflammatory transcription factor Krüppel-like transcription factor 2 (KLF2). Sustained expression of KLF2 reduced and deficiency of KLF2 enhanced gram-positive endotoxins induced HIF-1α mRNA and protein expression in macrophages. More importantly, KLF2 attenuated gram-positive endotoxins induced cellular motility and proinflammatory gene expression in myeloid cells. Consistent with these results, mice deficient in myeloid HIF-1α were protected from gram-positive endotoxin-induced sepsis mortality and clinical symptomatology. By contrast, myeloid KLF2-deficient mice were susceptible to gram-positive sepsis induced mortality and clinical symptoms.

Conclusions: Substantial agreement exists among a large cohort of international experts regarding many strong recommendations for the best care of patients with sepsis. Although a significant number of aspects of care have relatively weak support, evidence-based recommendations regarding the acute management of sepsis and septic shock are the foundation of improved outcomes for these critically ill patients with high mortality.", "title": "Surviving Sepsis Campaign: International Guidelines for Management of Sepsis and Septic Shock 2016" }, { "docid": "1522647", "text": "BACKGROUND Mitochondrial DNA (mtDNA) is a critical activator of inflammation and the innate immune system. However, mtDNA level has not been tested for its role as a biomarker in the intensive care unit (ICU). We hypothesized that circulating cell-free mtDNA levels would be associated with mortality and improve risk prediction in ICU patients. METHODS AND FINDINGS Analyses of mtDNA levels were performed on blood samples obtained from two prospective observational cohort studies of ICU patients (the Brigham and Women's Hospital Registry of Critical Illness [BWH RoCI, n = 200] and Molecular Epidemiology of Acute Respiratory Distress Syndrome [ME ARDS, n = 243]). mtDNA levels in plasma were assessed by measuring the copy number of the NADH dehydrogenase 1 gene using quantitative real-time PCR. Medical ICU patients with an elevated mtDNA level (≥3,200 copies/µl plasma) had increased odds of dying within 28 d of ICU admission in both the BWH RoCI (odds ratio [OR] 7.5, 95% CI 3.6-15.8, p = 1×10(-7)) and ME ARDS (OR 8.4, 95% CI 2.9-24.2, p = 9×10(-5)) cohorts, while no evidence for association was noted in non-medical ICU patients. The addition of an elevated mtDNA level improved the net reclassification index (NRI) of 28-d mortality among medical ICU patients when added to clinical models in both the BWH RoCI (NRI 79%, standard error 14%, p<1×10(-4)) and ME ARDS (NRI 55%, standard error 20%, p = 0.007) cohorts. In the BWH RoCI cohort, those with an elevated mtDNA level had an increased risk of death, even in analyses limited to patients with sepsis or acute respiratory distress syndrome. Study limitations include the lack of data elucidating the concise pathological roles of mtDNA in the patients, and the limited numbers of measurements for some of biomarkers.

Ang-2 is raised in severe sepsis but the mechanisms underlying this are not known. Nitric oxide (NO) inhibits WPB exocytosis, and bioavailability of endothelial NO is decreased in sepsis. We hypothesized that endothelial NO bioavailability would be inversely correlated with ang-2 concentrations in sepsis. METHODS Plasma ang-2, vascular endothelial growth factor (VEGF) and endothelial-active cytokines were assessed in 83 patients with early sepsis and 41 hospital controls, and related to reactive hyperaemia-peripheral arterial tonometry, RH-PAT, a measure of endothelial NO bioavailability. RESULTS Plasma Ang-2 was elevated in sepsis (median [interquartile range (IQR)], ng/ml: severe sepsis 12.4 [8.5-33.4], sepsis without organ failure 6.1 [5.0-10.4], controls 2.7 [2.2-3.6], P < 0.0001).

The correlation of ang-2 with RH-PAT persisted after controlling for sepsis severity. In a longitudinal mixed-effects model, recovery of RH-PAT over time was associated with decline in ang-2.

OBJECTIVE To quantify the dose-response association between leisure time physical activity and mortality and define the upper limit of benefit or harm associated with increased levels of physical activity. DESIGN, SETTING, AND PARTICIPANTS We pooled data from 6 studies in the National Cancer Institute Cohort Consortium (baseline 1992-2003). Population-based prospective cohorts in the United States and Europe with self-reported physical activity were analyzed in 2014.

Comprehensive evidence of the long-term effects of contemporary surgery on a broad range of clinical outcomes in large populations treated in routine clinical practice is lacking. The objective of this study was to measure the association between bariatric surgery, weight, body mass index, and obesity-related co-morbidities. METHODS AND FINDINGS This was an observational retrospective cohort study using data from the United Kingdom Clinical Practice Research Datalink. All 3,882 patients registered in the database and with bariatric surgery on or before 31 December 2014 were included and matched by propensity score to 3,882 obese patients without surgery. The main outcome measures were change in weight and body mass index over 4 y; incident diagnoses of type 2 diabetes mellitus (T2DM), hypertension, angina, myocardial infarction (MI), stroke, fractures, obstructive sleep apnoea, and cancer; mortality; and resolution of hypertension and T2DM. Weight measures were available for 3,847 patients between 1 and 4 mo, 2,884 patients between 5 and 12 mo, and 2,258 patients between 13 and 48 mo post-procedure. Bariatric surgery patients exhibited rapid weight loss for the first four postoperative months, at a rate of 4.98 kg/mo (95% CI 4.88-5.08). Slower weight loss was sustained to the end of 4 y. Gastric bypass (6.56 kg/mo) and sleeve gastrectomy (6.29 kg/mo) were associated with greater initial weight reduction than gastric banding (2.77 kg/mo). Protective hazard ratios (HRs) were detected for bariatric surgery for incident T2DM, 0.68 (95% CI 0.55-0.83); hypertension, 0.35 (95% CI 0.27-0.45); angina, 0.59 (95% CI 0.40-0.87);MI, 0.28 (95% CI 0.10-0.74); and obstructive sleep apnoea, 0.55 (95% CI 0.40-0.87). Strong associations were found between bariatric surgery and the resolution of T2DM, with a HR of 9.29 (95% CI 6.84-12.62), and between bariatric surgery and the resolution of hypertension, with a HR of 5.64 (95% CI 2.65-11.99). No association was detected between bariatric surgery and fractures, cancer, or stroke.

CONCLUSIONS Bariatric surgery as delivered in the UK healthcare system is associated with dramatic weight loss, sustained at least 4 y after surgery. This weight loss is accompanied by substantial improvements in pre-existing T2DM and hypertension, as well as a reduced risk of incident T2DM, hypertension, angina, MI, and obstructive sleep apnoea.

METHODS We did a two-by-two factorial, cluster-randomised trial in Dadu, a rural area of Sindh province, Pakistan. Clusters were defined as the population covered by a functional traditional birth attendant (TBA), and were randomly allocated to one of four groups (groups A to D) with a computer-generated random number sequence. Implementation and data collection teams were masked to allocation. Liveborn infants delivered by participating TBAs who received birth kits were eligible for enrolment in the study. One intervention comprised birth kits containing 4% CHX solution for application to the cord at birth by TBAs and once daily by family members for up to 14 days along with soap and educational messages promoting handwashing. One intervention was CHX solution only and another was handwashing only. Standard dry cord care was promoted in the control group. The primary outcomes were incidence of neonatal omphalitis and neonatal mortality. The trial is registered with ClinicalTrials.gov, number NCT00682006. FINDINGS 187 clusters were randomly allocated to one of the four study groups. Of 9741 newborn babies delivered by participating TBAs, factorial analysis indicated a reduction in risk of omphalitis with CHX application (risk ratio [RR]=0·58, 95% CI 0·41-0·82; p=0·002) but no evidence of an effect of handwashing (RR=0·83, 0·61-1·13; p=0·24). We recorded strong evidence of a reduction in neonatal mortality in neonates who received CHX cleansing (RR=0·62, 95 % CI 0·45-0·85; p=0·003) but no evidence of an effect of handwashing promotion on neonatal mortality (RR=1·08, 0·79-1·48; p=0·62).

Social, demographic and ethnicity measures from the 1981 and 1991 censuses and standardised annual AIDS-related mortality rates for young men are used to calculate Poisson regression models. A strong association was found between all TB mortality groups and overcrowding at the household level. For women, no other measures improved the explanatory power of the models. In multiple regressions, both poverty and AIDS-related mortality explained additional variation in the model for younger men. The link between ethnicity and tuberculosis notifications was not reflected in this analysis of mortality. For all groups no evidence of a positive relationship with ethnicity was found, once overcrowding had been accounted for. The significance of household as opposed to district level crowding suggests that prolonged contact is required for disease transmission. Regression analysis indicates that it is the overcrowding and poverty among ethnic populations that is significant for their tuberculosis mortality.

RESULTS Compared to buffer-treated controls, rhAng-1 treated septic mice showed significant improvements in several hematologic and biochemical indicators of MODS. Moreover, rhAng-1 stabilized endothelial barrier function, as evidenced by inhibition of protein leakage from lung capillaries into the alveolar compartment. Histological analysis revealed that rhAng-1 treatment attenuated leukocyte infiltration in lungs and kidneys of septic mice, probably due to reduced endothelial adhesion molecule expression in rhAng-1 treated mice. Finally, the protective effects of rhAng-1 treatment were reflected by an improved survival time in a lethal CLP model. CONCLUSIONS In a clinically relevant murine sepsis model, intravenous rhAng-1 treatment alone is sufficient to significantly improve a variety of sepsis-associated organ dysfunctions and survival time, most likely by preserving endothelial barrier function.

Early closure of the ductus arteriosus may be achieved pharmacologically using cyclooxygenase inhibitors or by surgery. The efficacy of both treatment modalities is well established. However, the preferred initial treatment of a symptomatic PDA in a preterm infant, surgical ligation or treatment with indomethacin, has not been well established. OBJECTIVES To compare the effect of surgical ligation of PDA vs. medical treatment with cyclooxygenase inhibitors (using indomethacin, ibuprofen, or mefenamic acid), each used as the initial treatment, on neonatal mortality in preterm infants with a symptomatic PDA. SEARCH STRATEGY The standard search strategy of the Cochrane Neonatal Review Group was used. This included search of electronic databases: Cochrane Central Register of Controlled Trials (CENTRAL, The Cochrane Library, Issue 2, 2007), MEDLINE (1966 - July 2007), CINAHL (1982 - July 2007), EMBASE (1980 - July 2007); and hand search of abstracts of Pediatric Academic Societies annual meetings published in Pediatric Research (1990 - April 2002) or on line from May 2002 -July 2007. No language restrictions were applied. SELECTION CRITERIA All trials 1) using randomized or quasi-randomized patient allocation, 2) in preterm infants < 37 weeks gestational age or low-birth-weight infants (< 2500 grams) with symptomatic PDA in the neonatal period (< 28 days) and 3) comparing surgical ligation with medical treatment with cyclooxygenase inhibitors, each used as the initial treatment for closure of PDA. DATA COLLECTION AND ANALYSIS Assessment of methodological quality and extraction of data for included trials was undertaken independently by the authors. RevMan 4.1 was used for analysis of the data. MAIN RESULTS Only one study, trial B in the report of Gersony 1983, was found eligible. No additional studies were identified in the literature searches performed in July 2007. The trial compared the effect of surgical ligation of PDA vs. medical treatment with indomethacin, each used as the primary treatment. No trials comparing surgery to other cyclooxygenase inhibitors (ibuprofen, mefenamic acid) were found. Trial B of Gersony 1983 enrolled 154 infants. The study found no statistically significant difference between surgical closure and indomethacin treatment in mortality during hospital stay, chronic lung disease, other bleeding, necrotizing enterocolitis, sepsis, creatinine level, or intraventricular hemorrhage. There was a statistically significant increase in the surgical group in incidence of pneumothorax [RR 2.68 (95% CI 1.45, 4.93); RD 0.25 (95% CI 0.11, 0.38); NNH 4 (95% CI 3, 9)] and retinopathy of prematurity stage III and IV [RR 3.80 (95% CI 1.12, 12.93); RD 0.11 (95% CI 0.02, 0.20), NNH 9 (95% CI 5, 50] compared to the indomethacin group. There was as expected a statistically significant decrease in failure of ductal closure rate in the surgical group as compared to the indomethacin group: [RR 0.04 (95% CI 0.01, 0.27); RD -0.32 (95% CI -0.43, -0.21), NNT 3 (95% CI 2, 4)]. AUTHORS' CONCLUSIONS The data regarding net benefit/harm are insufficient to make a conclusion as to whether surgical ligation or medical treatment with indomethacin is preferred as initial treatment for symptomatic PDA in preterm infants. It should be noted that three recent observational studies indicated an increased risk for one or more of the following outcomes associated with PDA ligation; chronic lung disease, retinopathy of prematurity and neurosensory impairment . It is possible that the duration of the \"waiting-time\" and transport to another facility with surgical capacity to have the PDA ligated could adversely affect outcomes, as could the perioperative care.", "title": "Surgical versus medical treatment with cyclooxygenase inhibitors for symptomatic patent ductus arteriosus in preterm infants." }, { "docid": "21932297", "text": "The important life-supporting role of hydrogen sulfide (H(2)S) has evolved from bacteria to plants, invertebrates, vertebrates, and finally to mammals. Over the centuries, however, H(2)S had only been known for its toxicity and environmental hazard. Physiological importance of H(2)S has been appreciated for about a decade. It started by the discovery of endogenous H(2)S production in mammalian cells and gained momentum by typifying this gasotransmitter with a variety of physiological functions. The H(2)S-catalyzing enzymes are differentially expressed in cardiovascular, neuronal, immune, renal, respiratory, gastrointestinal, reproductive, liver, and endocrine systems and affect the functions of these systems through the production of H(2)S. The physiological functions of H(2)S are mediated by different molecular targets, such as different ion channels and signaling proteins. Alternations of H(2)S metabolism lead to an array of pathological disturbances in the form of hypertension, atherosclerosis, heart failure, diabetes, cirrhosis, inflammation, sepsis, neurodegenerative disease, erectile dysfunction, and asthma, to name a few. Many new technologies have been developed to detect endogenous H(2)S production, and novel H(2)S-delivery compounds have been invented to aid therapeutic intervention of diseases related to abnormal H(2)S metabolism.

Increased levels of distress and anxiety are common during the waiting period of any subsequent pregnancies, posing a significant threat to psychological well-being. However, only limited support and therapy are available for these women, and many are left to cope alone. The Positive Reappraisal Coping Intervention (PRCI) is a novel self-administered supportive technique which has been shown to be effective in patients awaiting the outcome of in vitro fertilisation treatment. The primary objective of this study is to assess the feasibility and effectiveness of the PRCI in improving quality of life in the difficult waiting period which women with previous RM endure before an ongoing pregnancy can be confirmed. METHODS AND ANALYSIS A randomised controlled trial (RCT) feasibility study will establish the viability of conducting a multicentre RCT to definitively test the effects of the PRCI on the psychological well-being of women who have experienced RM during the initial waiting period of a subsequent pregnancy. A second component consists of a qualitative process evaluation exploring the initial experience of pregnancy following repeated miscarriages. Participants (n=50) will be randomised into one of two groups. The PRCI intervention group will receive the PRCI card and weekly questionnaires to assess their psychological well-being during the waiting period of their new pregnancy. The non-intervention group will be asked to complete the same weekly questionnaires. The qualitative process analysis will employ semistructured interviews (n=20) to address relevant aspects of the study objectives.

We aimed to quantify the total mortality burden attributable to non-optimum ambient temperature, and the relative contributions from heat and cold and from moderate and extreme temperatures. METHODS We collected data for 384 locations in Australia, Brazil, Canada, China, Italy, Japan, South Korea, Spain, Sweden, Taiwan, Thailand, UK, and USA. We fitted a standard time-series Poisson model for each location, controlling for trends and day of the week. We estimated temperature-mortality associations with a distributed lag non-linear model with 21 days of lag, and then pooled them in a multivariate metaregression that included country indicators and temperature average and range. We calculated attributable deaths for heat and cold, defined as temperatures above and below the optimum temperature, which corresponded to the point of minimum mortality, and for moderate and extreme temperatures, defined using cutoffs at the 2·5th and 97·5th temperature percentiles. FINDINGS We analysed 74,225,200 deaths in various periods between 1985 and 2012. In total, 7·71% (95% empirical CI 7·43-7·91) of mortality was attributable to non-optimum temperature in the selected countries within the study period, with substantial differences between countries, ranging from 3·37% (3·06 to 3·63) in Thailand to 11·00% (9·29 to 12·47) in China. The temperature percentile of minimum mortality varied from roughly the 60th percentile in tropical areas to about the 80-90th percentile in temperate regions. More temperature-attributable deaths were caused by cold (7·29%, 7·02-7·49) than by heat (0·42%, 0·39-0·44). Extreme cold and hot temperatures were responsible for 0·86% (0·84-0·87) of total mortality. INTERPRETATION Most of the temperature-related mortality burden was attributable to the contribution of cold. The effect of days of extreme temperature was substantially less than that attributable to milder but non-optimum weather. This evidence has important implications for the planning of public-health interventions to minimise the health consequences of adverse temperatures, and for predictions of future effect in climate-change scenarios.

Since the structure and function of the retinal vasculature greatly resembles the cerebral vasculature, study of retinal changes can reveal insights into the pathophysiology of cerebral malaria. A detailed observational study of malarial retinopathy in Bangladeshi adults was performed using high-definition portable retinal photography. Retinopathy was present in 17/27 adults (63%) with severe malaria and 14/20 adults (70%) with cerebral malaria.

The spectrum of malarial retinopathy was similar to that previously described in African children, but no vessel discolouration was observed. The severity of retinal whitening correlated with admission venous plasma lactate (P=0.046), suggesting that retinal ischaemia represents systemic ischaemia.

The objective of this study was to quantify the overall impact of lifestyle-related factors beyond that of active cigarette smoking and alcohol consumption on all-cause and cause-specific mortality in Chinese women. METHODS AND FINDINGS We used data from the Shanghai Women's Health Study, an ongoing population-based prospective cohort study in China. Participants included 71,243 women aged 40 to 70 years enrolled during 1996-2000 who never smoked or drank alcohol regularly. A healthy lifestyle score was created on the basis of five lifestyle-related factors shown to be independently associated with mortality outcomes (normal weight, lower waist-hip ratio, daily exercise, never exposed to spouse's smoking, higher daily fruit and vegetable intake). The score ranged from zero (least healthy) to five (most healthy) points. During an average follow-up of 9 years, 2,860 deaths occurred, including 775 from cardiovascular disease (CVD) and 1,351 from cancer. Adjusted hazard ratios for mortality decreased progressively with an increasing number of healthy lifestyle factors. Compared to women with a score of zero, hazard ratios (95% confidence intervals) for women with four to five factors were 0.57 (0.44-0.74) for total mortality, 0.29 (0.16-0.54) for CVD mortality, and 0.76 (0.54-1.06) for cancer mortality. The inverse association between the healthy lifestyle score and mortality was seen consistently regardless of chronic disease status at baseline. The population attributable risks for not having 4-5 healthy lifestyle factors were 33% for total deaths, 59% for CVD deaths, and 19% for cancer deaths. CONCLUSIONS In this first study, to our knowledge, to quantify the combined impact of lifestyle-related factors on mortality outcomes in Chinese women, a healthier lifestyle pattern-including being of normal weight, lower central adiposity, participation in physical activity, nonexposure to spousal smoking, and higher fruit and vegetable intake-was associated with reductions in total and cause-specific mortality among lifetime nonsmoking and nondrinking women, supporting the importance of overall lifestyle modification in disease prevention.

It spread to encompass much of Afghanistan , and then the northern parts of the Indian subcontinent at least as far as Saketa and Sarnath near Varanasi ( Benares ) , where inscriptions have been found dating to the era of the Kushan emperor Kanishka the Great . Emperor Kanishka was a great patron of Buddhism ; however , as Kushans expanded southward , the deities of their later coinage came to reflect its new Hindu majority . The Kushans were one of five branches of the Yuezhi confederation , a possibly Iranic or Tocharian , Indo-European nomadic people who migrated from Gansu and settled in ancient Bactria . The Kushans possibly used the Greek language initially for administrative purposes , but soon began to use Bactrian language . Kanishka sent his armies north of the Karakoram mountains , capturing territories as far as Kashgar , Khotan and Yarkant , in the Tarim Basin of modern-day Xinjiang , China . A direct road from Gandhara to China remained under Kushan control for more than a century , encouraging travel across the Karakoram and facilitating the spread of Mahayana Buddhism to China . The Kushan dynasty had diplomatic contacts with the Roman Empire , Sasanian Persia , Aksumite Empire and Han China . While much philosophy , art , and science was created within its borders , the only textual record of the empire 's history today comes from inscriptions and accounts in other languages , particularly Chinese . The Kushan empire fragmented into semi-independent kingdoms in the 3rd century AD , which fell to the Sasanians invading from the west . In the 4th century , the Guptas , an Indian dynasty also pressed from the east . The last of the Kushan and Sasanian kingdoms were eventually overwhelmed by invaders from the north , known as the Hepthalites . Historian H. G.

Its territory covers 652,000 km2 , making it the 41st largest country in the world . Human habitation in Afghanistan dates back to the Middle Paleolithic Era , and the country 's strategic location along the Silk Road connected it to the cultures of the Middle East and other parts of Asia . Through the ages the land has been home to various peoples and witnessed numerous military campaigns , notably by Alexander the Great , Mauryas , Muslim Arabs , Mongols , British , Soviet , and in the modern era by Western powers . The land also served as the source from which the Kushans , Hephthalites , Samanids , Saffarids , Ghaznavids , Ghorids , Khiljis , Mughals , Hotaks , Durranis , and others have risen to form major empires . The political history of the modern state of Afghanistan began with the Hotak and Durrani dynasties in the 18th century .

A randomized, double-blind, placebo-controlled clinical trial was conducted in 65 pre- and mildly hypertensive adults, age 30-70 y, not taking blood pressure (BP)-lowering medications, with either 3 240-mL servings/d of brewed hibiscus tea or placebo beverage for 6 wk.

At 6 wk, hibiscus tea lowered systolic BP (SBP) compared with placebo (-7.2 +/- 11.4 vs. -1.3 +/- 10.0 mm Hg; P = 0.030). Diastolic BP was also lower, although this change did not differ from placebo (-3.1 +/- 7.0 vs. -0.5 +/- 7.5 mm Hg; P = 0.160).

Although phenolic acids were found in plasma without any modification in their structures, most flavonols were found as quercetin or kaempferol glucuronide conjugates. Flavonol glucuronide conjugates, which show longer half-life elimination values, are proposed to contribute to the observed lipid peroxidation inhibitory activity in the cellular membranes.

Patients were evaluated using the International Prostate Symptom Score (IPSS), the maximum urinary flow rate (Qmax), postvoid residual urine volume (PVR), Serum Prostatic- Specific Antigen (PSA), testosterone levels, and prostate size. At the end of 6-month trial, unblinding revealed that patients who initially received the placebo were switched to Urtica dioica. Both groups continued the medication up to 18 months. RESULTS: 558 patients (90%) completed the study (287/305, 91% in the Urtica dioica group, and 271/315, 86% in the placebo group). By intention- to-treat analysis, at the end of 6-month trial, 232 (81%) of 287 patients in the Urtica dioica group reported improved LUTS compared with 43 (16%) of 271 patients in the placebo group (P < 0.001).

OBJECTIVE To conduct a systematic review and meta-analysis of controlled clinical trials and observational studies that have examined the association between vegetarian diets and BP. DATA SOURCES MEDLINE and Web of Science were searched for articles published in English from 1946 to October 2013 and from 1900 to November 2013, respectively. STUDY SELECTION All studies met the inclusion criteria of the use of (1) participants older than 20 years, (2) vegetarian diets as an exposure or intervention, (3) mean difference in BP as an outcome, and (4) a controlled trial or observational study design. In addition, none met the exclusion criteria of (1) use of twin participants, (2) use of multiple interventions, (3) reporting only categorical BP data, or (4) reliance on case series or case reports.

MAIN OUTCOMES AND MEASURES Net differences in systolic and diastolic BP associated with the consumption of vegetarian diets were assessed. RESULTS Of the 258 studies identified, 7 clinical trials and 32 observational studies met the inclusion criteria. In the 7 controlled trials (a total of 311 participants; mean age, 44.5 years), consumption of vegetarian diets was associated with a reduction in mean systolic BP (-4.8 mm Hg; 95% CI, -6.6 to -3.1; P < .001; I2 = 0; P = .45 for heterogeneity) and diastolic BP (-2.2 mm Hg; 95% CI, -3.5 to -1.0; P < .001; I2 = 0; P = .43 for heterogeneity) compared with the consumption of omnivorous diets. In the 32 observational studies (a total of 21,604 participants; mean age, 46.6 years), consumption of vegetarian diets was associated with lower mean systolic BP (-6.9 mm Hg; 95% CI, -9.1 to -4.7; P < .001; I2 = 91.4; P < .001 for heterogeneity) and diastolic BP (-4.7 mm Hg; 95% CI, -6.3 to -3.1; P < .001; I2 = 92.6; P < .001 for heterogeneity) compared with the consumption of omnivorous diets.

(HS) in the treatment of risk factors associated with cardiovascular disease is assessed in this review by taking a comprehensive approach to interpreting the randomized clinical trial (RCT) results in the context of the available ethnomedical, phytochemical, pharmacological, and safety and toxicity information. HS decoctions and infusions of calyxes, and on occasion leaves, are used in at least 10 countries worldwide in the treatment of hypertension and hyperlipidemia with no reported adverse events or side effects. HS extracts have a low degree of toxicity with a LD50 ranging from 2,000 to over 5,000 mg/kg/day. There is no evidence of hepatic or renal toxicity as the result of HS extract consumption, except for possible adverse hepatic effects at high doses. There is evidence that HS acts as a diuretic, however in most cases the extract did not significantly influence electrolyte levels. Animal studies have consistently shown that consumption of HS extract reduces blood pressure in a dose dependent manner. In RCTs, the daily consumption of a tea or extract produced from HS calyxes significantly lowered systolic blood pressure (SBP) and diastolic blood pressure (DBP) in adults with pre to moderate essential hypertension and type 2 diabetes. In addition, HS tea was as effective at lowering blood pressure as the commonly used blood pressure medication Captropril, but less effective than Lisinopril. Total cholesterol, low-density lipoprotein cholesterol (LDL-C), and triglycerides were lowered in the majority of normolipidemic, hypolipidemic, and diabetic animal models, whereas high-density lipoprotein cholesterol (HDL-C) was generally not affected by the consumption of HS extract. Over half of the RCTs showed that daily consumption of HS tea or extracts had favorable influence on lipid profiles including reduced total cholesterol, LDL-C, triglycerides, as well as increased HDL-C. Anthocyanins found in abundance in HS calyxes are generally considered the phytochemicals responsible for the antihypertensive and hypocholesterolemic effects, however evidence has also been provided for the role of polyphenols and hibiscus acid. A number of potential mechanisms have been proposed to explain the hypotensive and anticholesterol effects, but the most common explanation is the antioxidant effects of the anthocyanins inhibition of LDL-C oxidation, which impedes atherosclerosis, an important cardiovascular risk factor. This comprehensive body of evidence suggests that extracts of HS are promising as a treatment of hypertension and hyperlipidemia, however more high quality animal and human studies informed by actual therapeutic practices are needed to provide recommendations for use that have the potential for widespread public health benefit.", "title": "Hibiscus sabdariffa L. in the treatment of hypertension and hyperlipidemia: a comprehensive review of animal and human studies" }, { "docid": "MED-1842", "text": "Considering the high prevalence of hypertension, its debilitating end organ damage, and the side effects of chemical drugs used for its treatment, we conducted this experimental study to evaluate the effect of sour tea (Hibiscus sabdariffa) on essential hypertension.

Hibiscus sabdariffa is a plant known in many countries and is consumed as hot and cold drinks In addition to its use in folk medicine; it has been suggested as treatment for many conditions including hypertension. OBJECTIVES: The objectives of this review were to examine the evidence of effectiveness and safety of hibiscus in the treatment of hypertension. METHODS: We searched several medical databases (MEDLINE, EMBASE, CINAHL, Cochrane Central Register of Controlled Trials, and the specialized register of the Cochrane Hypertension Group and the general engine Google) to January 2009. We included randomized controlled trials that had examined Hibiscus's effectiveness and safety in the treatment of primary hypertension in adults. Two authors independently selected the trials for the review, extracted the data, and critically appraised the included studies. RESULTS: Four trials, with a total of 390 patients, met our inclusion criteria. Two studies compared Hibiscus sabdariffa to black tea; one study compared it to captopril and one to lisinopril. The studies found that Hibiscus had greater blood pressure reduction than tea but less than the ACE-inhibitors. However, all studies, except one, were short term and of poor quality with a Jadad scoring of <3 and did not meet international standards. CONCLUSION: The four randomized controlled studies identified in this review do not provide reliable evidence to support recommending Hibiscus sabdariffa for the treatment of primary hypertension in adults.

The Dietary Approaches to Stop Hypertension (DASH) diet also lowers BP. To date, no trial has evaluated the effects of simultaneously implementing these lifestyle recommendations. OBJECTIVE: To determine the effect on BP of 2 multicomponent, behavioral interventions. DESIGN, SETTING, AND PARTICIPANTS: Randomized trial with enrollment at 4 clinical centers (January 2000-June 2001) among 810 adults (mean [SD] age, 50 [8.9] years; 62% women; 34% African American) with above-optimal BP, including stage 1 hypertension (120-159 mm Hg systolic and 80-95 mm Hg diastolic), and who were not taking antihypertensive medications. INTERVENTION: Participants were randomized to one of 3 intervention groups: (1) \"established,\" a behavioral intervention that implemented established recommendations (n = 268); (2) \"established plus DASH,\"which also implemented the DASH diet (n = 269); and (3) an \"advice only\" comparison group (n = 273). MAIN OUTCOME MEASURES: Blood pressure measurement and hypertension status at 6 months. RESULTS: Both behavioral interventions significantly reduced weight, improved fitness, and lowered sodium intake. The established plus DASH intervention also increased fruit, vegetable, and dairy intake. Across the groups, gradients in BP and hypertensive status were evident. After subtracting change in advice only, the mean net reduction in systolic BP was 3.7 mm Hg (P<.001) in the established group and 4.3 mm Hg (P<.001) in the established plus DASH group; the systolic BP difference between the established and established plus DASH groups was 0.6 mm Hg (P =.43). Compared with the baseline hypertension prevalence of 38%, the prevalence at 6 months was 26% in the advice only group, 17% in the established group (P =.01 compared with the advice only group), and 12% in the established plus DASH group (P<.001 compared with the advice only group; P =.12 compared with the established group). The prevalence of optimal BP (<120 mm Hg systolic and <80 mm Hg diastolic) was 19% in the advice only group, 30% in the established group (P =.005 compared with the advice only group), and 35% in the established plus DASH group (P<.001 compared with the advice only group; P =.24 compared with the established group).

The biokinetic variables were the areas under the curve (AUC) of plasma FRAP, ascorbic acid and urate that are above the pre-dose concentration, and the amounts excreted into urine within 24 h (Ae(0-24) ) of antioxidants as assayed by FRAP, ascorbic acid, uric acid, malondialdehyde (biomarker for oxidative stress), and hippuric acid (metabolite and potential biomarker for total polyphenol intake). RESULTS: HSE caused significantly higher plasma AUC of FRAP, an increase in Ae(0-24) of FRAP, ascorbic acid and hippuric acid, whereas malondialdehyde excretion was reduced. Furthermore, the main hibiscus anthocyanins as well as one glucuronide conjugate could be quantified in the volunteers' urine (0.02% of the administered dose). CONCLUSION: The aqueous HSE investigated in this study enhanced the systemic AOP and reduced the oxidative stress in humans. Furthermore, the increased urinary hippuric acid excretion after HSE consumption indicates a high biotransformation of the ingested HSE polyphenols, most likely caused by the colonic microbiota.

Before that time the toxic effects of aluminium ingestion were not considered to be a major concern because absorption seemed unlikely to occur. Meanwhile, aluminium toxicity has been investigated in countless epidemiological and clinical studies as well as in animal experiments and many papers have been published on the subject. It is now commonly acknowledged that aluminium toxicity can be induced by infusion of aluminium-contaminated dialysis fluids, by parenteral nutrition solutions, and by oral exposure as a result of aluminium-containing pharmaceutical products such as aluminium-based phosphate binders or antacid intake. Over-the-counter antacids are the most important source for human aluminium exposure from a quantitative point of view. However, aluminium can act as a powerful neurological toxicant and provoke embryonic and fetal toxic effects in animals and humans after gestational exposure. Despite these facts, the patient information leaflets from European antacids that are available OTC show substantial differences regarding warnings from aluminium toxicity.

DESIGN: We assessed Mn intakes (food frequency questionnaire), fasting whole blood and plasma Mn levels, and quantitative expression of peripheral blood mononuclear cell Mn-dependent superoxide dismutase (MnSOD) and cytosolic aminopeptidase-P (cAP-P). SETTING AND SUBJECTS: In total, 24 tea drinkers (> or = 1 l black tea/day) and 28 non-tea drinkers were recruited from the staff and students of King's College London by circular email. RESULTS: Dietary Mn intakes (mean (range)) were significantly lower (P < 0.0001) in non tea drinkers (3.2 mg/day (0.5-6.5)) than tea drinkers (5.5 mg/day (2-12) or 10 mg/day (5-20) depending upon the value used for Mn levels of black tea).

In this study the inhibitory effects of Rooibos and the dihydrochalcones, aspalathin and nothofagin, were investigated on adrenal steroidogenesis. The activities of both cytochrome P450 17α-hydroxylase/17,20 lyase and cytochrome P450 21-hydroxylase were significantly inhibited in COS-1 cells. In order to study the effect of these compounds in H295R cells, a human adrenal carcinoma cell line, a novel UPLC-MS/MS method was developed for the detection and quantification of twenty-one steroid metabolites using a single chromatographic separation. Under both basal and forskolin-stimulated conditions, the total amount of steroids produced in H295R cells significantly decreased in the presence of Rooibos, aspalathin and nothofagin. Under stimulated conditions, Rooibos decreased the total steroid output 4-fold and resulted in a significant reduction of aldosterone and cortisol precursors. Dehydroepiandrosterone-sulfate levels were unchanged, while the levels of androstenedione (A4) and 11β-hydroxyandrostenedione (11βOH-A4) were inhibited 5.5 and 2.3-fold, respectively. Quantification of 11βOH-A4 showed this metabolite to be a major product of steroidogenesis in H295R cells and we confirm, for the first time, that this steroid metabolite is the product of the hydroxylation of A4 by human cytochrome P450 11β-hydroxylase. Taken together our results demonstrate that Rooibos, aspalathin and nothofagin influence steroid hormone biosynthesis and the flux through the mineralocorticoid, glucocorticoid and androgen pathways, thus possibly contributing to the alleviation of negative effects arising from elevated glucocorticoid levels.

This investigation evaluates the structural effect that stinging nettle spicules may have on the clinical manifestation of these symptoms. This hypothesis was investigated by exposing murine skin to stinging nettles and then evaluating the skin using electron microscopy. It was hypothesized that the mechanism of action of stinging nettles is both biochemical and mechanical, which may have clinical significance regarding treatment for acute exposure. METHODS: Fresh post-mortem dermis samples from the carcasses of genetically modified hairless mice were brushed under the stem and leaf of a stinging nettle plant, mimicking the clinical method of exposure a patient might experience. Another set of mouse skin samples was obtained but not exposed to the nettles. Both sets of skin samples were imaged with scanning electron microscopy. RESULTS: The skin samples that were not exposed to nettle leaves were uniform, with occasional striated hairs on the skin surface and no nettle spicules. The skin samples exposed to nettle leaves showed many smooth nettle spicules piercing the skin surface. A few spicules retained their bases, which appear empty of any liquid contents. CONCLUSIONS: The mechanism of action of stinging nettles dermatitis appears to be both biochemical and mechanical. Impalement of spicules into the skin likely accounts for the mechanical irritation in addition to the known adverse chemical effects of stinging nettles.

METHODS: Bag teas were purchased to represent black, green, citrus, fruity, and floral tea flavors from Tulsi, Bigelow, HyVee, Tazo, and Yogi brands and brewed (1 bag/240 ml) in boiling water for 3 minutes. The pH, titratable acidity, and fluoride concentrations were measured. Following these measurements, a representative tea from each flavor was selected for investigation of erosion potential. Six extracted human molars were randomly assigned to each tea. Teeth were painted with fingernail polish to expose a 1 x 4 mm window and then soaked in tea for a total of 25 hours with teas refreshed every 5 hours. Teeth were then sectioned using a microtome and photographed using a polarized light microscope. Lesion depths (i.e., eroded surfaces) were measured using Image Pro Plus software. Differences in physiochemical properties and lesion depths between beverages were investigated using one-way ANOVA with post-hoc Tukey's HSD test.

The aim of this study was to evaluate gastro-oesophageal reflux induced by coffee and tea before and after a decaffeination process, and to compare it with water and water-containing caffeine. METHODS: Three-hour ambulatory pH-metry was performed on 16 healthy volunteers, who received 300 ml of (i) regular coffee, decaffeinated coffee or tap water (n = 16), (ii) normal tea, decaffeinated tea, tap water, or coffee adapted to normal tea in caffeine concentration (n = 6), and (iii) caffeine-free and caffeine-containing water (n = 8) together with a standardized breakfast. RESULTS: Regular coffee induced a significant (P < 0.05) gastro-oesophageal reflux compared with tap water and normal tea, which were not different from each other. Decaffeination of coffee significantly (P < 0.05) diminished gastro-oesophageal reflux, whereas decaffeination of tea or addition of caffeine to water had no effect. Coffee adapted to normal tea in caffeine concentration significantly (P < 0.05) increased gastro-oesophageal reflux. CONCLUSIONS: Coffee, in contrast to tea, increases gastro-oesophageal reflux, an effect that is less pronounced after decaffeination.

DESIGN: We performed a search in 3 databases for meta-analyses and compared them with studies they subsumed. We performed an additional search for subsequent studies to determine whether the conclusions were consistent. RESULTS: Many epidemiologic studies have been conducted and summarized in 5 meta-analyses on either tea consumption or flavonoid consumption and cardiovascular disease or the subset of stroke. Heterogeneity of effect was seen when the outcome included all cardiovascular diseases. In the case of stroke, a consistent, dose-response association with tea consumption on both incidence and mortality was noted with RRs of 0.80 (95% CI: 0.65, 0.98) for flavonoids and 0.79 (95% CI: 0.73, 0.85) for tea when high and low intakes were compared or the addition of 3 cups/d was estimated.

Direct effects of tea components on the vasculature, particularly the endothelium, may partly explain this association. Objective We performed a meta-analysis of controlled human intervention studies on the effect of tea on flow-mediated dilation (FMD) of the brachial artery, a measurement of endothelial function, which is suggested to be associated with cardiovascular risk. Methods Human intervention studies were identified by systematic search of the databases Medline, Embase, Chemical s and Biosis through March 2009 and by hand-searching related articles. Studies were selected based on predefined criteria: intervention with tea as the sole experimental variable, placebo-controlled design, and no missing data on FMD outcome or its variability. A random effects model was used to calculate the pooled overall effect on FMD due to the intake of tea. The impact of various subject and treatment characteristics was investigated in the presence of heterogeneity. Results In total, 9 studies from different research groups were included with 15 relevant study arms. The overall absolute increase in FMD of tea vs. placebo was 2.6% of the arterial diameter (95% CI: 1.8-3.3%; P-value <0.001) for a median daily dose of 500 mL of tea (2–3 cups). This is a relative increase of approximately 40% compared to the average FMD of 6.3% measured under placebo or baseline conditions. There was significant heterogeneity between studies (P-value <0.001) that might partly be explained by the cuff position either distal or proximal to the area of FMD measurement. No indication for publication bias was found. Conclusion Moderate consumption of tea substantially enhances endothelial-dependent vasodilation.

[ { "docid": "MED-4292", "text": "There is currently no single dietary or lifestyle intervention that is effective in long-term weight loss. Traditional weight loss diets tend to be low in total fat and therefore often restrict nut consumption. However, nuts are an important source of many vitamins, minerals, monounsaturated and polyunsaturated fatty acids. This paper reviewed all the available evidence from the literature in relation to nut consumption and body weight. The findings show that the role of nut consumption in body weight management is varied. Nuts, when included as part of an energy-controlled diet, were found in some instances to assist with weight loss. However, when nuts were added to an existing diet without controlling for energy intake, body weight increased, although to a lesser extent than theoretically predicted. There is limited evidence on the effect nut consumption has on type 2 diabetes, although available evidence indicates that nuts as part of a healthy diet do not cause weight gain and can have a positive influence on the fatty acid profile of a person with diabetes. This review shows there is a lack of evidence to support the restriction of nut consumption in weight management, indicating that further research is needed to assess the role of nuts in weight management.", "title": "A review of the evidence: nuts and body weight." }, { "docid": "MED-4286", "text": "Nuts are rich sources of multiple nutrients and phytochemicals associated with health benefits, including reduced cardiovascular disease risk. This has prompted recommendations to increase their consumption. However, they are also high in fat and are energy dense. The associations between these properties, positive energy balance and body weight raise questions about such recommendations. Numerous epidemiological and clinical studies show that nuts are not associated with weight gain. Mechanistic studies indicate this is largely attributable to the high satiety and low metabolizable energy (poor bioaccessibility leading to inefficient energy absorption) properties of nuts. Compensatory dietary responses account for 55-75% of the energy provided by nuts. Limited data suggest that routine nut consumption is associated with elevated resting energy expenditure and the thermogenic effect of feeding, resulting in dissipation of another portion of the energy they provide. Additionally, trials contrasting weight loss through regimens that include or exclude nuts indicate improved compliance and greater weight loss when nuts are permitted. Nuts may be included in the diet, in moderation, to enhance palatability, nutrient quality, and chronic disease risk reduction without compromising weight loss or maintenance.", "title": "Nuts and healthy body weight maintenance mechanisms." } ]
[ { "docid": "MED-2237", "text": "In India, lung cancer is one of the most common and lethal cancers, and tobacco smoking remains its most important etiologic factors. The objective of our study is to examine the effects of different tobacco consumption forms, including smoking and chewing, on lung cancer risk of men in southern India, especially to compare the effects of bidi smoking to cigarette smoking on lung carcinogenesis. We also evaluated the possible role of Indian alcohol beverages and non-Indian alcohol beverages on lung carcinogenesis. We conducted a case-control study in Chennai and Trivandrum. In total, 778 lung cancer cases and 3,430 controls, including 1,503 cancer controls and 1,927 healthy controls, were recruited. The effects of cigarette, bidi smoking, chewing and alcohol drinking on the risk of lung cancer were estimated from unconditional multivariate logistic regression. We also applied the generalized additive model (GAM) with locally-weighted running-line smoothers (loess) to find the most plausible curve for the dose-response relationship. The results from GAM suggest a plateau after 35 years of smoking or 10 cigarette-equivalent pack-years for both cigarette and bidi. The OR is 4.54 (95%CI=2.96-6.95) and 6.45 (95%CI=4.38-9.50) for more than 30 years of cigarette-only and bidi-only smoking, respectively, and 6.87 (95%CI=4.62-10.2) and 10.7 (95%CI=5.82-19.6) for more than 12 weighted cumulative cigarette-only and bidi-only consumption, respectively. The lung cancer risk of former cigarette smokers drops down more quickly after quitting smoking compared to former bidi smokers. There is no evidence for the effect of chewing and lung cancer risk nor clear evidence of an effect of overall alcohol drinking among never-smokers, although Indian alcohol drinking seemed to remain associated with lung cancer risk under limited power (OR=2.67, 95%CI=1.02-7.02). Bidi smoking seems to have a stronger carcinogenic effect than cigarette smoking: this difference holds no matter which aspect of smoking was considered.

However, the association between betel-nut chewing and risk for chronic kidney disease (CKD) is unknown.

METHODS: We retrospectively reviewed health-check records of 3264 men in a hospital-based cross-sectional screening programme from 2003 to 2006. CKD was defined as estimated glomerular filtration rate less than 60 ml/min/1.73 m2 calculated by the Modification of Diet in Renal Disease formula. Risk factors for CKD including diabetes, hypertension, BMI, smoking, alcohol consumption and age were also considered. RESULTS: A total of 677 (20.7 %) men were found to have CKD and 427 (13.1 %) participants reported a history of betel-nut use. The prevalence (24.8 %) of CKD in betel-nut users was significantly higher than that (11.3 %) of participants without betel-nut use (P = 0.026).

METHODS: Self-identified Chinese (n = 32) and European (n = 31) healthy volunteers attended on eight occasions for studies following ingestion of glucose and jasmine, basmati, brown, Doongara(®) and parboiled rice. In addition to measuring glycaemic response, we investigated physical activity levels, extent of chewing of rice and salivary α-amylase activity to determine whether these measures explained any differences in postprandial glycaemia. RESULTS: Glycaemic response, measured by incremental area under the glucose curve, was over 60% greater for the five rice varieties (P < 0.001) and 39% greater for glucose (P < 0.004) amongst Chinese compared with Europeans. The calculated glycaemic index was approximately 20% greater for rice varieties other than basmati (P = 0.01 to 0.05). Ethnicity [adjusted risk ratio 1.4 (1.2-1.8) P < 0.001] and rice variety were the only important determinants of incremental area under the glucose curve. CONCLUSIONS: Glycaemic responses following ingestion of glucose and several rice varieties are appreciably greater in Chinese compared with Europeans, suggesting the need to review recommendations regarding dietary carbohydrate amongst rice-eating populations at high risk of diabetes. © 2012 The Authors.

Some studies have reported favorable immune function-related effects on biological secretions such as blood and breast milk in humans who have ingested a chlorella-derived multicomponent supplement. However, the effects of chlorella-derived supplement on mucosal immune functions remain unclear. The purpose of this study was to investigate whether chlorella ingestion increases the salivary secretory immunoglobulin A (SIgA) secretion in humans using a blind, randomized, crossover study design. Methods Fifteen men took 30 placebo and 30 chlorella tablets per day for 4 weeks separated by a 12-week washout period. Before and after each trial, saliva samples were collected from a sterile cotton ball that was chewed after overnight fasting. Salivary SIgA concentrations were measured using ELISA. Results Compliance rates for placebo and chlorella ingestions were 97.0 ± 1.0% and 95.3 ± 1.6%, respectively. No difference was observed in salivary SIgA concentrations before and after placebo ingestion (P = 0.38). However, salivary SIgA concentrations were significantly elevated after chlorella ingestion compared to baseline (P < 0.01). No trial × period interaction was identified for the saliva flow rates. Although the SIgA secretion rate was not affected by placebo ingestion (P = 0.36), it significantly increased after 4-week chlorella ingestion than before intake (P < 0.01). Conclusions These results suggest 4-week ingestion of a chlorella-derived multicomponent supplement increases salivary SIgA secretion and possibly improves mucosal immune function in humans.", "title": "Salivary Secretory Immunoglobulin a secretion increases after 4-weeks ingestion of chlorella-derived multicomponent supplement in humans: a randomized cross over study" }, { "docid": "MED-2179", "text": "OBJECTIVE: To investigate the association between cooking behaviour and long-term survival among elderly Taiwanese. DESIGN: Cohort study. The duration of follow-up was the interval between the date of interview and the date of death or 31 December 2008, when censored for survivors. Information used included demographics, socio-economic status, health behaviours, cooking frequencies, physical function, cognitive function, nutrition knowledge awareness, eating out habits and food and nutrient intakes. These data were linked to death records. Cox proportional-hazards models were used to evaluate cooking frequency on death from 1999 to 2008 with related covariate adjustments.

RESULTS: During a 10-year follow-up, 695 participants died. Those who cooked most frequently were younger, women, unmarried, less educated, non-drinkers of alcohol, non-smokers, without chewing difficulty, had spouse as dinner companion, normal cognition, who walked or shopped more than twice weekly, who ate less meat and more vegetables. Highly frequent cooking (>5 times/week, compared with never) predicted survival (hazard ratio (HR) = 0·47; 95 % CI, 0·36, 0·61); with adjustment for physical function, cognitive function, nutrition knowledge awareness and other covariates, HR was 0·59 (95 % CI, 0·41, 0·86). Women benefited more from cooking more frequently than did men, with decreased HR, 51 % v. 24 %, when most was compared with least.

This study quantifies the amount of titanium in common food products, derives estimates of human exposure to dietary (nano-) TiO2, and discusses the impact of the nanoscale fraction of TiO2 entering the environment. The foods with the highest content of TiO2 included candies, sweets and chewing gums. Among personal care products, toothpastes and select sunscreens contained 1% to >10% titanium by weight. While some other crèmes contained titanium, despite being colored white, most shampoos, deodorants, and shaving creams contained the lowest levels of titanium (<0.01 μg/mg). For several high-consumption pharmaceuticals, the titanium content ranged from below the instrument detection limit (0.0001 μg Ti/mg) to a high of 0.014 μg Ti/mg. Electron microscopy and stability testing of food-grade TiO2 (E171) suggests that approximately 36% of the particles are less than 100 nm in at least one dimension and that it readily disperses in water as fairly stable colloids. However, filtration of water solubilized consumer products and personal care products indicated that less than 5% of the titanium was able to pass through 0.45 or 0.7 μm pores. Two white paints contained 110 μg Ti/mg while three sealants (i.e., prime coat paint) contained less titanium (25 to 40 μg Ti/mg). This research showed that while many white-colored products contained titanium, it was not a prerequisite. Although several of these product classes contained low amounts of titanium, their widespread use and disposal down the drain and eventually to WWTPs deserves attention. A Monte Carlo human exposure analysis to TiO2 through foods identified children as having the highest exposures because TiO2 content of sweets is higher than other food products, and that a typical exposure for a US adult may be on the order of 1 mg Ti per kilogram body weight per day. Thus, because of the millions of tons of titanium based white pigment used annually, testing should focus on food-grade TiO2 (E171) rather than that adopted in many environmental health and safety tests (i.e., P25), which is used in much lower amounts in products less likely to enter the environment (e.g., catalyst supports, photocatalytic coatings).", "title": "Titanium Dioxide Nanoparticles in Food and Personal Care Products" }, { "docid": "MED-2668", "text": "Polyphenol compounds found in berry fruits, in particular flavonoids, have been associated with health benefits including improvement in cognition and neuronal function with aging.

METHODS: We used factor analysis to identify a low-risk behavior-based dietary pattern in 24 444 postmenopausal women from the population-based prospective Swedish Mammography Cohort who were free of diagnosed cancer, cardiovascular disease, and diabetes mellitus at baseline (September 15, 1997). We also defined 3 low-risk lifestyle factors: nonsmoking, waist-hip ratio less than the 75th percentile (< 0.85), and being physically active (at least 40 minutes of daily walking or bicycling and 1 hour of weekly exercise). RESULTS: During 6.2 years (151 434 person-years) of follow-up, we ascertained 308 cases of primary MI. Two major identified dietary patterns, \"healthy\" and \"alcohol,\" were significantly associated with decreased risk of MI. The low-risk diet (high scores for the healthy dietary pattern) characterized by a high intake of vegetables, fruit, whole grains, fish, and legumes, in combination with moderate alcohol consumption (>/= 5 g of alcohol per day), along with the 3 low-risk lifestyle behaviors, was associated with 92% decreased risk (95% confidence interval, 72%-98%) compared with findings in women without any low-risk diet and lifestyle factors.

Cases had a higher daily intake of food mutagens and mutagenicity activity (revertants per gram of daily meat intake) than controls did. The daily intakes of 2-amino-3,4,8-trimethylimidazo[4,5—f]quinoxaline (DiMeIQx) and benzo(a)pyrene (BaP), as well as the mutagenic activity, were significant predictors for pancreatic cancer (P = 0.008, 0.031, and 0.029, respectively) with adjustment of other confounders.

MATERIALS AND METHODS: Organ doses as a function of age-at-diagnosis were estimated for common CT examinations, and estimated attributable lifetime cancer mortality risks (per unit dose) for different organ sites were applied. Standard models that assume a linear extrapolation of risks from intermediate to low doses were applied. On the basis of current standard practice, the same exposures (milliampere-seconds) were assumed, independent of age. RESULTS: The larger doses and increased lifetime radiation risks in children produce a sharp increase, relative to adults, in estimated risk from CT. Estimated lifetime cancer mortality risks attributable to the radiation exposure from a CT in a 1-year-old are 0.18% (abdominal) and 0.07% (head)-an order of magnitude higher than for adults-although those figures still represent a small increase in cancer mortality over the natrual background rate. In the United States, of approximately 600,000 abdominal and head CT examinations annually performed in children under the age of 15 years, a rough estimate is that 500 of these individuals might ultimately die from cancer attributable to the CT radiation. CONCLUSION: The best available risk estimates suggest that pediatric CT will result in significantly increased lifetime radiation risk over adult CT, both because of the increased dose per milliampere-second, and the increased lifetime risk per unit dose. Lower milliampere-second settings can be used for children without significant loss of information. Although the risk-benefit balance is still strongly tilted toward benefit, because the frequency of pediatric CT examinations is rapidly increasing, estimates that quantitative lifetime radiation risks for children undergoing CT are not negligible may stimulate more active reduction of CT exposure settings in pediatric patients.", "title": "Estimated risks of radiation-induced fatal cancer from pediatric CT." }, { "docid": "MED-902", "text": "The cytotoxicity of extracts from a widely used species of plant, Moringa stenopetala, was assessed in HEPG2 cells, by measuring the leakage of lactate dehydrogenase (LDH) and cell viability.

The ethanol extracts of leaves and seeds increased significantly (p < 0.01) LDH leakage in a dose- and time-dependent manner. The water extract of leaves and the ethanol extract of the root did not increase LDH leakage. A highly significant (p < 0.001) decrease in HEPG2 viability was found after incubating the cells with the highest concentration (500 microg/mL) of the ethanol leaf and seed extracts. At a concentration of 500 microg/mL, the water extract of leaves increased (p < 0.01), while the ethanol extract of the same plant part decreased (p < 0.01), ATP levels. The root and seed extracts had no significant effect on ATP levels. The ethanol leaf extract decreased GSH levels at a concentration of 500 microg/mL (p < 0.01), as did the ethanol extract of the seeds at 250 microg/mL and 500 microg/mL (p < 0.05). The water extract of the leaves did not alter GSH or LDH levels or affect cell viability, suggesting that it may be non-toxic, and is consistent with its use as a vegetable. The data obtained from the studies with the ethanol extract of the leaves and seeds from Moringa stenopetala show that they contain toxic substances that are extractable with organic solvents or are formed during the process of extraction with these solvents. The significant depletion of ATP and GSH only occurred at concentrations of extract that caused leakage of LDH.

Extensive research has been completed to evaluate the relationship between dietary factors and breast cancer risk and survival after breast cancer; however, a summary report with clinical inference is needed. Materials and METHODS: This review summarizes the current epidemiological and clinical trial evidence relating diet to breast cancer incidence, recurrence, survival, and mortality. The review includes emerging epidemiological studies that assess risk within breast cancer subtypes as well as a summary of previous and ongoing dietary intervention trials designed to modify breast cancer risk. RESULTS: The available literature suggests that both low-fat and high-fiber diets may be weakly protective against breast cancer, whereas total energy intake and alcohol appear to be positively associated. Fiber may be weakly protective possibly through modulation of estrogen, whereas fruit and vegetable intake is not clearly associated with risk. Obesity is a risk factor for postmenopausal disease, and adult weight gain should be avoided to reduce risk. In survivors, diet has the greatest potential influence on overall mortality rather than breast cancer-specific events.

The aims of this study were to describe any latitudinal variation in the prevalence of childhood allergy in Australia and to evaluate, in parallel, the individual associations between ultraviolet radiation (UVR)- and vitamin D-related measures and hayfever asthma and both conditions. Participants were population-based controls who took part in a multicenter case-control study, aged 18-61 yr and resident in one of four study regions ranging in latitude from 27°S to 43°S. Data were derived from a self-administered questionnaire, interview and examination by a research officer and biologic sampling. Latitude and longitude coordinates were geocoded from participants' residential locations and climatic data were linked to postcodes of current residence. Stored serum was analyzed for 25-hydroxyvitamin D concentrations and silicone rubber casts of the skin were used as an objective measure of cumulative actinic damage. There was an inverse latitude gradient for asthma (a 9% decrease per increasing degree of latitude); however, this pattern did not persist after adjusting for average daily temperature. There was no association between any of the UVR- or vitamin D-related measures and childhood asthma, but greater time in the sun in winter between the ages 6-15 yr was associated with an increase in the odds of having hayfever [adjusted odds ratios (OR) 1.29; 95% CI 1.01-1.63]. Oral supplementation with cod liver oil in childhood increased the odds of a history of having both asthma and hayfever (2.87; 1.00-8.32).

In this overview, the evidence regarding meat consumption and the risk of diabetes, both type 1 diabetes (T1DM) and T2DM and their macro- and microvascular complications, is reviewed. For T2DM, we performed a new meta-analysis including publications up to October 2012. For T1DM, only a few studies have reported increased risks for meat consumers or for high intake of saturated fatty acids and nitrates and nitrites. For T2DM, CHD, and stroke, the evidence is strongest. Per 100 g of total meat, the pooled relative risk (RR) for T2DM is 1.15 (95 % CI 1.07-1.24), for (unprocessed) red meat 1.13 (95 % CI 1.03-1.23), and for poultry 1.04 (95 % CI 0.99-1.33); per 50 g of processed meat, the pooled RR is 1.32 (95 % CI 1.19-1.48). Hence, the strongest association regarding T2DM is observed for processed (red) meat. A similar observation has been made for CHD. For stroke, however, a recent meta-analysis shows moderately elevated risks for meat consumers, for processed as well as for fresh meats. For the microvascular complications of diabetes, few prospective data were available, but suggestions for elevated risks can be derived from findings on hyperglycemia and hypertension.

Modification by calcium intake (dietary or total) above or below 800 mg/d was assessed by interaction terms. Overall, mean age was 69 ± 0.3y. Among women, there was no association between NEAP and BMD. PRALdiet was positively associated with proximal femur BMD (p trend=0.04). No associations were observed with PRALtotal at any BMD site (P-range: 0.38–0.82). Among men, no significant associations were observed of BMD with NEAP or PRAL.

To add further information on dietary patterns potentially associated to pancreatic cancer, we applied an exploratory principal component factor analysis on 28 major nutrients derived from an Italian case-control study. METHODS: Cases were 326 incident pancreatic cancer cases and controls 652 frequency-matched controls admitted to hospital for non-neoplastic diseases. Dietary information was collected through a validated and reproducible food frequency questionnaire. Multiple logistic regression models adjusted for sociodemographic variables and major recognized risk factors for pancreatic cancer were used to estimate the odds ratios (OR) of pancreatic cancer for each dietary pattern. RESULTS: We identified four dietary patterns-named \"animal products,\" \"unsaturated fats,\" \"vitamins and fiber,\" and \"starch rich,\" that explain 75% of the total variance in nutrient intake in this population. After allowing for all the four patterns, positive associations were found for the animal products and the starch rich patterns, the OR for the highest versus the lowest quartiles being 2.03 (95% confidence interval [CI], 1.29-3.19) and 1.69 (95% CI, 1.02-2.79), respectively; an inverse association emerged for the vitamins and fiber pattern (OR, 0.55; 95% CI, 0.35-0.86), whereas no association was observed for the unsaturated fats pattern (OR, 1.13; 95% CI, 0.71-1.78).

Results The highest incorporation of EPA+DHA into plasma PL was provoked by krill oil (mean AUC0-72 h: 80.03 ± 34.71%*h), followed by fish oil rTAG (mean AUC0-72 h: 59.78 ± 36.75%*h) and EE (mean AUC0-72 h: 47.53 ± 38.42%*h). Due to high standard deviation values, there were no significant differences for DHA and the sum of EPA+DHA levels between the three treatments. However, a trend (p = 0.057) was observed for the differences in EPA bioavailability. Statistical pair-wise group comparison's revealed a trend (p = 0.086) between rTAG and krill oil. FA analysis of the supplements showed that the krill oil sample contained 22% of the total EPA amount as free EPA and 21% of the total DHA amount as free DHA, while the two fish oil samples did not contain any free FA. Conclusion Further studies with a larger sample size carried out over a longer period are needed to substantiate our findings and to determine differences in EPA+DHA bioavailability between three common chemical forms of LC n-3 FA (rTAG, EE and krill oil).

In contrast, carbohydrate-rich foods such as vegetables, fruits, whole grains, and milk contain relatively few AGEs, even after cooking. The formation of new dAGEs during cooking was prevented by the AGE inhibitory compound aminoguanidine and significantly reduced by cooking with moist heat, using shorter cooking times, cooking at lower temperatures, and by use of acidic ingredients such as lemon juice or vinegar.

Therefore, we sought to investigate this question with tremendous public health implications. Data on mortality rates of cancers of the breast, colon, prostate, esophagus, and stomach for China (1988-2000), Hong Kong (1960-2006), Japan (1950-2006), Korea (1985-2006), and Singapore (1963-2006) were obtained from WHO. Joinpoint regression was used to investigate trends in mortality of these cancers. A remarkable increase in mortality rates of breast, colon, and prostate cancers and a precipitous decrease in those of esophageal and stomach cancers have been observed in selected countries (except breast cancer in Hong Kong) during the study periods. For example, the annual percentage increase in breast cancer mortality was 5.5% (95% confidence interval: 3.8, 7.3%) for the period 1985-1993 in Korea, and mortality rates for prostate cancer significantly increased by 3.2% (95% confidence interval: 3.0, 3.3%) per year from 1958 to 1993 in Japan.

During the 17-year follow-up, we identified 543 incident diabetes cases. RESULTS: (1) Subjects who were weekly consumers of all meats were 29% (OR = 1.29; 95% CI 1.08, 1.55) more likely (relative to zero meat intake) to develop diabetes. (2) Subjects who consumed any processed meats (salted fish and frankfurters) were 38% (OR = 1.38; 95% CI 1.05-1.82) more likely to develop diabetes.

Participants with cancer, heart disease, and stroke were excluded. Coffee consumption was assessed once at baseline. Results During 5,148,760 person-years of follow-up between 1995 and 2008, a total of 33,731 men and 18,784 women died. In age-adjusted models, the risk of death was increased among coffee drinkers.

DESIGN Randomised, participant and single assessor blinded, controlled study. SETTING Department of orthopaedics in a Swedish university hospital. PARTICIPANTS 102 patients with long standing (over six months) persistent subacromial impingement syndrome in whom earlier conservative treatment had failed, recruited through orthopaedic specialists. INTERVENTIONS The specific exercise strategy consisted of strengthening eccentric exercises for the rotator cuff and concentric/eccentric exercises for the scapula stabilisers in combination with manual mobilisation. The control exercise programme consisted of unspecific movement exercises for the neck and shoulder. Patients in both groups received five to six individual guided treatment sessions during 12 weeks. In between these supervised sessions the participants performed home exercises once or twice a day for 12 weeks. MAIN OUTCOME MEASURES The primary outcome was the Constant-Murley shoulder assessment score evaluating shoulder function and pain. Secondary outcomes were patients' global impression of change because of treatment and decision regarding surgery. RESULTS Most (97, 95%) participants completed the 12 week study. There was a significantly greater improvement in the Constant-Murley score in the specific exercise group than in the control exercise group (24 points (95% confidence interval 19 to 28.0) v 9 points (5 to 13); mean difference between group: 15 points (8.5 to 20.6)). Significantly more patients in the specific exercise group reported successful outcome (defined as large improvement or recovered) in the patients' global assessment of change because of treatment: 69% (35/51) v 24% (11/46); odds ratio 7.6, 3.1 to 18.9; P<0.001. A significantly lower proportion of patients in the specific exercise group subsequently chose to undergo surgery: 20% (10/51) v 63% (29/46); odds ratio 7.7, 3.1 to 19.4; P<0.001). CONCLUSION A specific exercise strategy, focusing on strengthening eccentric exercises for the rotator cuff and concentric/eccentric exercises for the scapula stabilisers, is effective in reducing pain and improving shoulder function in patients with persistent subacromial impingement syndrome.

This review of corticosteroid injections for shoulder pain is one in a series of reviews of varying interventions for shoulder disorders. OBJECTIVES To determine the efficacy and safety of corticosteroid injections in the treatment of adults with shoulder pain. SEARCH STRATEGY MEDLINE, EMBASE, CINAHL, Central and Science Citation Index were searched up to and including June 2002. SELECTION CRITERIA Randomised and pseudo-randomised trials in all languages of corticosteroid injections compared to placebo or another intervention, or of varying types and dosages of steroid injection in adults with shoulder pain. Specific exclusions were duration of shoulder pain less than three weeks, rheumatoid arthritis, polymyalgia rheumatica and fracture. DATA COLLECTION AND ANALYSIS Trial inclusion and methodological quality was assessed by two independent reviewers according to predetermined criteria. Results are presented separately for rotator cuff disease, adhesive capsulitis, full thickness rotator cuff tear and mixed diagnoses, and, where possible, combined in meta-analysis. MAIN RESULTS Twenty-six trials met inclusion criteria. The number, site and dosage of injections varied widely between studies. The number of participants per trial ranged from 20 to 114 (median 52 participants). Methodological quality was variable. For rotator cuff disease, subacromial steroid injection was demonstrated to have a small benefit over placebo in some trials however no benefit of subacromial steroid injection over NSAID was demonstrated based upon the pooled results of three trials. For adhesive capsulitis, two trials suggested a possible early benefit of intra-articular steroid injection over placebo but there was insufficient data for pooling of any of the trials. One trial suggested short-term benefit of intra-articular corticosteroid injection over physiotherapy in the short-term (success at seven weeks RR=1.66 (1.21, 2.28). REVIEWER'S CONCLUSIONS Despite many RCTs of corticosteroid injections for shoulder pain, their small sample sizes, variable methodological quality and heterogeneity means that there is little overall evidence to guide treatment. Subacromial corticosteroid injection for rotator cuff disease and intra-articular injection for adhesive capsulitis may be beneficial although their effect may be small and not well-maintained. There is a need for further trials investigating the efficacy of corticosteroid injections for shoulder pain.

The 13 studies evaluated 14 clinical tests in 89 separate evaluations of diagnostic accuracy. Only one evaluation, palpation for supraspinatus ruptures, resulted in significant positive and negative likelihood ratios. Eight of the 89 evaluations resulted in either significant positive or negative likelihood ratios. However, none of these eight positive or negative likelihood ratios were found in other studies. Of the 89 evaluations of clinical tests 71 (80%) did not result in either significant positive or negative likelihood ratio evaluations across different studies. CONCLUSION Overall, most tests for rotator cuff pathology were inaccurate and cannot be recommended for clinical use. At best, suspicion of a rotator cuff tear may be heightened by a positive palpation, combined Hawkins/painful arc/infraspinatus test, Napoleon test, lift-off test, belly-press test, or drop-arm test, and it may be reduced by a negative palpation, empty can test or Hawkins-Kennedy test.", "title": "Most clinical tests cannot accurately diagnose rotator cuff pathology: a systematic review." }, { "docid": "11933721", "text": "UNLABELLED Biomechanical studies suggest a suture bridge technique enhances rotator cuff tendon footprint contact area, holding strength, and mean contact pressure. Based on these studies, we asked whether (1) the suture bridge technique would provide a high rate of cuff integrity after surgery, (2) the status of the repaired cuff would change with time, (3) preoperative factors could predict postoperative cuff integrity, and (4) patients with retears had less favorable pain, functional scores, range of motion (ROM), and muscle strength compared with those with intact repairs. We prospectively followed 78 patients with arthroscopic repairs in whom we used the suture bridge technique. The integrity of the rotator cuff repair was determined using ultrasonographic evaluation at 4.5 and 12 months after surgery. Ultrasonography revealed intact cuffs in 91% at 4.5 months postoperatively, all of which were maintained at the 12-month followup. Failure rates were 17.6% (three of 17) for massive tears, 11.1% (two of 18) for large tears, 6.3% (two of 32) for medium tears, and no failures for small tears. Preoperative fatty degeneration of the supraspinatus muscle was a strong predictor of cuff integrity. We found no correlation between the integrity and clinical outcomes except for a temporary decrease of abduction strength at 6 months.

Seventy-four patients with Type 2 diabetes were randomly assigned to either the experimental group (n = 37), which received a vegetarian diet, or the control group (n = 37), which received a conventional diabetic diet. Both diets were isocaloric, calorie restricted (-500 kcal/day). All meals during the study were provided. The second 12 weeks of the diet were combined with aerobic exercise. Participants were examined at baseline, 12 weeks and 24 weeks. Primary outcomes were: insulin sensitivity measured by hyperinsulinaemic isoglycaemic clamp; volume of visceral and subcutaneous fat measured by magnetic resonance imaging; and oxidative stress measured by thiobarbituric acid reactive substances. Analyses were by intention to treat. RESULTS Forty-three per cent of participants in the experimental group and 5% of participants in the control group reduced diabetes medication (P < 0.001).

Differences between groups were greater after the addition of exercise training. Changes in insulin sensitivity and enzymatic oxidative stress markers correlated with changes in visceral fat. CONCLUSIONS A calorie-restricted vegetarian diet had greater capacity to improve insulin sensitivity compared with a conventional diabetic diet over 24 weeks.

The 1-year incidence of SAEs was 33.3% (n = 5) in the allogeneic group and 53.3% (n = 8) in the autologous group (P = .46). At 1 year, there were no ventricular arrhythmia SAEs observed among allogeneic recipients compared with 4 patients (26.7%) in the autologous group (P = .10). Relative to baseline, autologous but not allogeneic MSC therapy was associated with an improvement in the 6-minute walk test and the MLHFQ score, but neither improved exercise VO2 max. Allogeneic and autologous MSCs reduced mean EED by −33.21% (95% CI, −43.61% to −22.81%; P < .001) and sphericity index but did not increase EF. Allogeneic MSCs reduced LV end-diastolic volumes. Low-dose concentration MSCs (20 million cells) produced greatest reductions in LV volumes and increased EF. Allogeneic MSCs did not stimulate significant donor-specific alloimmune reactions. CONCLUSIONS In this early-stage study of patients with ICM, transendocardial injection of allogeneic and autologous MSCs without a placebo control were both associated with low rates of treatment-emergent SAEs, including immunologic reactions. In aggregate, MSC injection favorably affected patient functional capacity, quality of life, and ventricular remodeling.

Six patients and six healthy matched controls performed knee-extensor exercise (KE) at 50% of maximum work rate before and after (only patients) KE training. Muscle biopsies were taken to assess skeletal muscle structure and the angiogenic response. Before training, during this submaximal KE exercise, patients with HFrEF exhibited higher leg vascular resistance and greater noradrenaline spillover. Skeletal muscle structure and VEGF response were generally not different between groups. Following training, resistance was no longer elevated and noradrenaline spillover was curtailed in the patients. Although, in the trained state, VEGF did not respond to acute exercise, capillarity was augmented. Muscle fibre cross-sectional area and percentage area of type I fibres increased and mitochondrial volume density exceeded that of controls. Structural/functional plasticity and appropriate angiogenic signalling were observed in skeletal muscle of patients with HFrEF. ABSTRACT This study examined the response to acute submaximal exercise and the effect of training in patients with heart failure with reduced ejection fraction (HFrEF). The acute angiogenic response to submaximal exercise in HFrEF after small muscle mass training is debated. The direct Fick method, with vascular pressures, was performed across the leg during knee-extensor exercise (KE) at 50% of maximum work rate (WRmax ) in patients (n = 6) and controls (n = 6) and then after KE training in patients. Muscle biopsies facilitated the assessment of skeletal muscle structure and vascular endothelial growth factor (VEGF) mRNA levels. Prior to training, HFrEF exhibited significantly higher leg vascular resistance (LVR) (≈15%) and significantly greater noradrenaline spillover (≈385%). Apart from mitochondrial volume density, which was significantly lower (≈22%) in HFrEF, initial skeletal muscle structure, including capillarity, was not different between groups. Resting VEGF mRNA levels, and the increase with exercise, was not different between patients and controls. Following training, LVR was no longer elevated and noradrenaline spillover was curtailed. Skeletal muscle capillarity increased with training, as assessed by capillary-to-fibre ratio (≈13%) and number of capillaries around a fibre (NCAF ) (≈19%). VEGF mRNA was now not significantly increased by acute exercise. Muscle fibre cross-sectional area and percentage area of type I fibres both increased significantly with training (≈18% and ≈21%, respectively), while the percentage area of type II fibres fell significantly (≈11%), and mitochondrial volume density now exceeded that of controls.

OBJECTIVE Our goal was to determine the effects of physical training intensity on the cardiovascular fitness, percentage of body fat (%BF), and visceral adipose tissue (VAT) of obese adolescents. DESIGN Obese 13-16-y-olds (n = 80) were assigned to 1) biweekly lifestyle education (LSE), 2) LSE + moderate-intensity physical training, or 3) LSE + high-intensity physical training. The intervention lasted 8 mo. Physical training was offered 5 d/wk, and the target energy expenditure for all subjects in physical training groups was 1047 kJ (250 kcal)/session. Cardiovascular fitness was measured with a multistage treadmill test, %BF with dual-energy X-ray absorptiometry, and VAT with magnetic resonance imaging. RESULTS The increase in cardiovascular fitness in the high-intensity physical training group, but not in the moderate-intensity group, was significantly greater than that in the LSE alone group (P = 0.009); no other comparisons of the 3 groups were significant. Compared with the LSE alone group, a group composed of subjects in both physical training groups combined who attended training sessions >or=2 d/wk showed favorable changes in cardiovascular fitness (P < 0.001), %BF (P = 0.001), and VAT (P = 0.029). We found no evidence that the high-intensity physical training was more effective than the moderate-intensity physical training in enhancing body composition.

The inoculation of Ehrlich tumor cells was performed at the end of the fourth week, and animals were killed after 6 wk of training. Heart and solid tumor weights were recorded, and tumor volumes were calculated. Portions of the tumors were used for the evaluation of macrophages and neutrophil accumulation or fixed in neutral 10% buffered formalin for histological analysis. The tumor volume and weight were, respectively, approximately 270% and 280% greater in sedentary mice than in trained mice. Macrophage infiltration in the tumor tissue was significantly lower in trained mice (0.65 +/- 0.16 vs. 1.78 +/- 0.43 macrophages x 10(3) in the sedentary group). Moreover, neutrophil accumulation in tumors was slightly reduced after exercise training, and the amount of tumor cells was reduced in trained mice.

Medication remained unchanged during the study period. Primary end points were the changes from baseline to week 15 in the distance walked in 6 minutes and in scores of the Short Form Health Survey quality-of-life questionnaire.

Patients were randomized from April 2003 through February 2007. INTERVENTIONS Usual care plus aerobic exercise training (n = 1172), consisting of 36 supervised sessions followed by home-based training, vs usual care alone (n = 1159). Randomization was stratified by heart failure etiology, which was a covariate in all models. MAIN OUTCOME MEASURES Kansas City Cardiomyopathy Questionnaire (KCCQ) overall summary scale and key subscales at baseline, every 3 months for 12 months, and annually thereafter for up to 4 years. The KCCQ is scored from 0 to 100 with higher scores corresponding to better health status. Treatment group effects were estimated using linear mixed models according to the intention-to-treat principle. RESULTS Median follow-up was 2.5 years. At 3 months, usual care plus exercise training led to greater improvement in the KCCQ overall summary score (mean, 5.21; 95% confidence interval, 4.42 to 6.00) compared with usual care alone (3.28; 95% confidence interval, 2.48 to 4.09).

Whether it or other genes activated in the athlete's heart might have an impact on cardiac function and survival in a setting of heart failure is unknown. To examine whether progressive exercise training and PI3K(p110alpha) activity affect survival and/or cardiac function in two models of heart disease, we subjected a transgenic mouse model of dilated cardiomyopathy (DCM) to swim training, genetically crossed cardiac-specific transgenic mice with increased or decreased PI3K(p110alpha) activity to the DCM model, and subjected PI3K(p110alpha) transgenics to acute pressure overload (ascending aortic constriction).

Exercise training and increased cardiac PI3K(p110alpha) activity prolonged survival in the DCM model by 15-20%. In contrast, reduced PI3K(p110alpha) activity drastically shortened lifespan by approximately 50%.

The relative importance of metabolic, myogenic, endothelium-mediated, and neurohumoral control systems varies throughout the coronary arterial tree, and these control systems contribute in parallel to regulating coronary vascular resistance to differing degrees at each level in the coronary arterial tree. In addition to this nonuniformity of the relative importance of vascular control systems in the coronary arterial tree, it appears that exercise training-induced adaptations are also distributed spatially, in a nonuniform manner throughout the coronary tree. As a result, it is necessary to examine training-induced adaptations throughout the coronary arterial tree. Adaptations in endothelium-mediated control play a role in training-induced changes in control of coronary vascular resistance, and there is evidence that the effects of training may be different in large coronary arteries than in the microcirculation. Also, there is evidence that the mode, frequency, and intensity of exercise training bouts and duration of training may influence the adaptive changes in endothelial function. Exercise training has also been shown to induce changes in responses of coronary vascular smooth muscle to vasoactive agents and alterations in the cellular-molecular control of intracellular Ca2+ in coronary vascular smooth muscle of conduit coronary arteries and to enhance myogenic reactivity of coronary resistance arteries. Exercise training also appears to have different effects on vascular smooth muscle in large coronary arteries than in the microcirculation. For example, adenosine sensitivity is increased in conduit coronary arteries and large resistance arteries after training but is not altered in small coronary resistance arteries of trained animals.

OBJECTIVE To conduct a systematic review of behavioral counseling for overweight and obese patients recruited from primary care, as delivered by primary care practitioners working alone or with trained interventionists (eg, medical assistants, registered dietitians), or by trained interventionists working independently. EVIDENCE REVIEW We searched PubMed, CINAHL, and EMBASE for randomized controlled trials published between January 1980 and June 2014 that recruited overweight and obese patients from primary care; provided behavioral counseling (ie, diet, exercise, and behavioral therapy) for at least 3 months, with at least 6 months of postrandomization follow-up; included at least 15 participants per treatment group and objectively measured weights; and had a comparator, an intention-to-treat analysis, and attrition of less than 30% at 1 year or less than 40% at longer follow-up.

Interventions that prescribed both reduced energy intake (eg, ≥ 500 kcal/d) and increased physical activity (eg, ≥150 minutes a week of walking), with traditional behavioral therapy, generally produced larger weight loss than interventions without all 3 specific components. In the former trials, more treatment sessions, delivered in person or by telephone by trained interventionists, were associated with greater mean weight loss and likelihood of patients losing 5% or more of baseline weight. CONCLUSIONS AND RELEVANCE Intensive behavioral counseling can induce clinically meaningful weight loss, but there is little research on primary care practitioners providing such care.

METHODS Twenty-three elite cold weather athletes (14 men, 9 women) PFT positive for EIA (FBC screened) served as subjects. Twenty-three gender and sport matched controls (nonasthmatics) were randomly selected to establish PFT reference values for normal elite athletes. Before FBC, athletes completed a medical history questionnaire for EIA symptoms. FBC evaluations consisted of baseline spirometry, actual or simulated competition, and 5, 10, and 15 min postexercise spirometry. PFT positive athletes were evaluated in the laboratory using an exercise challenge simulating race intensity (ambient conditions: 21 degrees C, 60% relative humidity). PFT procedures were identical to FBC. RESULTS 91% of PFT positive and 48% of PFT normal athletes reported at least one symptom of EIA, with postrace cough most frequent. Baseline spirometry was the same for PFT positives and normal controls. Lower limit reference range (MN - 2 SD) of FEV1 for controls suggests that postexercise decrements of greater than approximately -7% indicate abnormal airway response in this population. Exercise time duration did not effect bronchial reactivity; 78% of FBC PFT positives were PFT normal post-LBC. CONCLUSION Self-reported symptoms by elite athletes are not reliable in identifying EIA.

RESEARCH DESIGN AND METHODS After excluding two underweight patients (BMI <18.5 kg/m2), the study population comprised 831 consecutive patients with type 2 diabetes (mean age 61 +/- 9 years) referred for exercise testing for clinical reasons between 1995 and 2006. Exercise capacity was determined from a maximal exercise test and measured in metabolic equivalents (METs). Patients were classified both according to BMI category (18.5-24.9, 25.0-29.9, and > or =30 kg/m2) and by exercise capacity (<5.0 or > or =5.0 maximal METs). The association among exercise capacity, BMI, other clinical variables, and all-cause mortality was assessed by Cox proportional hazards. Study participants were followed for mortality up to 30 June 2006. RESULTS During a mean follow-up of 4.8 +/- 3.0 years, 112 patients died, for an average annual mortality rate of 2.2%. Each 1-MET increase in exercise capacity conferred a 10% survival benefit (hazard ratio 0.90 [95% CI 0.82-0.98]; P = 0.01), but BMI was not significantly associated with mortality. After adjustment for age, ethnicity, examination year, BMI, presence of cardiovascular disease (CVD), and CVD risk factors, diabetic patients achieving <5 maximal METs were 70% more likely to die (1.70 [1.13-2.54]) than those achieving > or =5 maximal METs.

Vascular endothelial cells also produce endothelin-1 (ET-1), which is a potent vasoconstrictor peptide and has potent proliferating activity on vascular smooth muscle cells. Therefore, ET-1 has been implicated in the progression of atheromatous vascular disease. Because exercise training has been reported to produce an alteration in the function of vascular endothelial cells in animals, we hypothesized that exercise training influences the production of NO and ET-1 in humans. The purpose of the present study was to examine whether chronic exercise could influence the plasma levels of NO (measured as the stable end product of NO, i.e., nitrite/nitrate [NOx]) and ET-1 in humans. Eight healthy young subjects (20.3 +/- 0.5 yr old) participated in the study and exercised by cycling on a leg ergometer (70% VO2max for 1 hour, 3-4 days/week) for 8 weeks. Venous plasma concentrations of NOx and ET-1 were measured before and after (immediately before the end of 8-week exercise training) the exercise training, and also after the 4th and 8th week after the cessation of training. The VO2max significantly increased after exercise training. After the exercise training, the plasma concentration of NOx significantly increased (30.69 +/- 3.20 vs. 48.64 +/- 8.16 micromol/L, p < 0.05), and the plasma concentration of ET-1 significantly decreased (1.65 +/- 0.14 vs. 1.23 +/- 0.12 pg/mL, p < 0.05). The increase in NOx level and the decrease in ET-1 level lasted to the 4th week after the cessation of exercise training and these levels (levels of NOx and ET-1) returned to the basal levels (the levels before the exercise training) in the 8th week after the cessation of exercise training. There was a significant negative correlation between plasma NOx concentration and plasma ET-1 concentration.

Smick's great book The World Is Curved: Hidden Dangers to the Global Economy. Chapter 6 of the book is titled \"\"Nothing Stays the Same: The 1992 Sterling Crisis.\"\" Here's a very brief excerpt; emphasis mine: [...] As this story shows, such blindness to the realities of a changing world can be very dangerous. In this case, the result was the brutal collapse of the British pound, which explains why the British people still use their own currency, the pound or sterling, and not the euro. The events that unfolded in the autumn of 1992 were totally unforeseen, yet they reshaped the European monetary world and represent a phenomenon that continues to impact global economies. [...] Smick's account of the events around 1992 runs about 28 pages. Here's my version, in a nutshell: At the time, Britain was part of the European Exchange Rate Mechanism, or ERM. The belief in Europe was that by uniting currencies under a common mechanism, Europe could gain influence in international financial policy largely dominated by the United States. The ERM was a precursor to monetary union. The Maastricht Treaty would eventually create the European Union and the euro. Britain joined the ERM later than other nations, in 1990, and after some controversy. Being part of the ERM required member nations to agree to expand and contract their currencies only within certain agreed upon limits called currency bands. Due to the way this had been structured, Germany's strong position placed it at the top of the system. At some point in 1992, Germany had raised interest rates to curb future inflation. However, Britain wanted Germany to cut rates – Britain was not in as enviable a position, economically speaking, and its currency was under pressure. The currency band system would put Britain in a tighter spot with Germany raising rates. Enter George Soros, the Hungarian billionaire, a.k.a. \"\"the man who broke the Bank of England.\"\" Soros took a huge short position against the Sterling. He believed the Sterling was overvalued relative to the German deutsche mark, and Britain would be forced to devalue its currency and realign with respect to the ERM. Other traders followed and also sold the Sterling short. With much pressure on the currency, the Bank of England had to buy up Sterling in order to maintain its agreement under the ERM. Of course, they needed to borrow other currencies to do this. Soon the BoE was in over its head defending the Sterling, realizing the exchange rate it needed to maintain under the ERM simply wasn't sustainable. Britain was forced to withdraw from the ERM on Black Wednesday, September 16th, 1992. And so, Britain does not use the euro today – and any talk of doing so is politically controversial. Therefore I wouldn't bet on Britain adopting the euro any time soon – too many of the players are still in politics and remember 1992 well. I think if Britain adopting the euro is ever to happen, it will be when the memory of 1992 has faded away. BTW, George Soros made off with more than US$1 billion.

Since the EURO is a fiat currency, like almost all developed nations, its \"\"promise\"\" comes from the expectation that its union and system will endure. The EURO is a basket of countries and as such could probably handle bailing out countries or possibly letting some default on their sovereign debt without killing the EURO itself. A similar reality happens in the United States with some level of regularity with state and municipal debt being considered riskier than Federal debt (it isn't uncommon for cities to default). The biggest reason the EURO will probably lose a LOT of value initially is if any nation defaults there isn't a track record as to how the EU member body will respond.

This lack of flexibility means that some of the key levers of international finance are compromised, for example a weak economy can't float its currency to improve exports.

This is being caused by two factors : sluggish growth in overseas economies and the ongoing strength of the US dollar. With many European government bonds offering negative redemption yields, income investors see US yields as relatively attractive. Those non-US economies which do not have negative bond yields either have near zero yields or large currency risks or both. Political issues such as the survival of the Euro also weigh heavily on market perceptions of the current attractiveness of the US dollar. Italian banks may be about to deliver a shock to the Eurozone, and the Spanish and French banks may not be far behind. Another factor is the continued threat of deflation. Growth is slowing around the world which negatively effects demand. Commodity prices remain depressed. Low growth and recession outside of the US translate into a prolonged period of near zero interest rates elsewhere together with renewed QE programmes in Europe, Japan, and possibly elsewhere. This makes the US look relatively attractive and so there is huge demand for US dollars and bonds.

Although Germany really doesn't want this due to their anti-inflationary ideology, if Italy comes crashing down, so does France. When France goes, Germany goes into a deep recession if not a depression. They have to devalue some. As for a collapse, I have no idea.

The market exchange-rate would likely be two or three drachmas to the euro, which would double or triple the Greek price of imported goods within a few days.

Those who moved their deposits abroad would be able to buy these assets cheaply, leading to a significant, regressive redistribution of Greek wealth. In short, you'd lose two-thirds of your savings unless you were storing them somewhere safe from the conversion. The article also predicts difficulty importing goods (other nations will demand to be paid in euro, not drachma) leading to disruption of trade and various supply shortages.

The fund in your question, however, is priced in EUR. For a fund like this to match the performance of the S&P500, which is priced in USD, as closely as possible, it needs to hedge against fluctuations in the EUR/USD exchange rate. If the fund simply converted EUR to USD then invested in an S&P500 index fund priced in USD, the EUR-priced fund may fail to match the USD-priced fund because of exchange rate fluctuations. Here is a simple example demonstrating why hedging is necessary. I assumed the current value of the USD-priced S&P500 index fund is 1,600 USD/share. The exchange rate is 1.3 USD/EUR. If you purchase one share of this index using EUR, you would pay 1230.77 EUR/share: If the S&P500 increases 10% to 1760 USD/share and the exchange rate remains unchanged, the value of the your investment in the EUR fund also increases by 10% (both sides of the equation are multiplied by 1.1): However, the currency risk comes into play when the EUR/USD exchange rate changes. Take the 10% increase in the price of the USD index occurring in tandem with an appreciation of the EUR to 1.4 USD/EUR: Although the USD-priced index gained 10%, the appreciation of the EUR means that the EUR value of your investment is almost unchanged from the first equation. For investments priced in EUR that invest in securities priced in USD, the presence of this additional currency risk mandates the use of a hedge if the indexes are going to track. The fund you linked to uses swap contracts, which I discuss in detail below, to hedge against fluctuations in the EUR/USD exchange rate. Since these derivatives aren't free, the cost of the hedge is included in the expenses of the fund and may result in differences between the S&P500 Index and the S&P 500 Euro Hedged Index. Also, it's important to realize that any time you invest in securities that are priced in a different currency than your own, you take on currency risk whether or not the investments aim to track indexes. This holds true even for securities that trade on an exchange in your local currency, like ADR's or GDR's. I wrote an answer that goes through a simple example in a similar fashion to the one above in that context, so you can read that for more information on currency risk in that context. There are several ways to investors, be they institutional or individual, can hedge against currency risk. iShares offers an ETF that tracks the S&P500 Euro Hedged Index and uses a over-the-counter currency swap contract called a month forward FX contract to hedge against the associated currency risk. In these contracts, two parties agree to swap some amount of one currency for another amount of another currency, at some time in the future. This allows both parties to effectively lock in an exchange rate for a given time period (a month in the case of the iShares ETF) and therefore protect themselves against exchange rate fluctuations in that period. There are other forms of currency swaps, equity swaps, etc. that could be used to hedge against currency risk. In general, two parties agree to swap one quantity, like a EUR cash flow, payments of a fixed interest rate, etc. for another quantity, like a USD cash flow, payments based on a floating interest rate, etc. In many cases these are over-the-counter transactions, there isn't necessarily a standardized definition. For example, if the European manager of a fund that tracks the S&P500 Euro Hedged Index is holding euros and wants to lock in an effective exchange rate of 1.4 USD/EUR (above the current exchange rate), he may find another party that is holding USD and wants to lock in the respective exchange rate of 0.71 EUR/USD. The other party could be an American fund manager that manages a USD-price fund that tracks the FTSE. By swapping USD and EUR, both parties can, at a price, lock in their desired exchange rates. I want to clear up something else in your question too. It's not correct that the \"\"S&P 500 is completely unrelated to the Euro.\"\" Far from it. There are many cases in which the EUR/USD exchange rate and the level of the S&P500 index could be related. For example: Troublesome economic news in Europe could cause the euro to depreciate against the dollar as European investors flee to safety, e.g. invest in Treasury bills. However, this economic news could also cause US investors to feel that the global economy won't recover as soon as hoped, which could affect the S&P500. If the euro appreciated against the dollar, for whatever reason, this could increase profits for US businesses that earn part of their profits in Europe. If a US company earns 1 million EUR and the exchange rate is 1.3 USD/EUR, the company earns 1.3 million USD. If the euro appreciates against the dollar to 1.4 USD/EUR in the next quarter and the company still earns 1 million EUR, they now earn 1.4 million USD. Even without additional sales, the US company earned a higher USD profit, which is reflected on their financial statements and could increase their share price (thus affecting the S&P500). Combining examples 1 and 2, if a US company earns some of its profits in Europe and a recession hits in the EU, two things could happen simultaneously. A) The company's sales decline as European consumers scale back their spending, and B) the euro depreciates against the dollar as European investors sell euros and invest in safer securities denominated in other currencies (USD or not). The company suffers a loss in profits both from decreased sales and the depreciation of the EUR. There are many more factors that could lead to correlation between the euro and the S&P500, or more generally, the European and American economies. The balance of trade, investor and consumer confidence, exposure of banks in one region to sovereign debt in another, the spread of asset/mortgage-backed securities from US financial firms to European banks, companies, municipalities, etc. all play a role. One example of this last point comes from this article, which includes an interesting line: Among the victims of America’s subprime crisis are eight municipalities in Norway, which lost a total of $125 million through subprime mortgage-related investments. Long story short, these municipalities had mortgage-backed securities in their investment portfolios that were derived from, far down the line, subprime mortgages on US homes. I don't know the specific cities, but it really demonstrates how interconnected the world's economies are when an American family's payment on their subprime mortgage in, say, Chicago, can end up backing a derivative investment in the investment portfolio of, say, Hammerfest, Norway.\"", "title": "" }, { "docid": "219398", "text": "Bitcoin can facilitate this, despite the risks associated with using bitcoin exchanges and the price volatility at any given time.

Results Among 141 311 patients with ICH (mean [SD] age, 68.3 [15.3] years; 48.1% women), 15 036 (10.6%) were taking warfarin and 4918 (3.5%) were taking NOACs preceding ICH, and 39 585 (28.0%) and 5783 (4.1%) were taking concomitant single and dual antiplatelet agents, respectively. Patients with prior use of warfarin or NOACs were older and had higher prevalence of atrial fibrillation and prior stroke. Acute ICH stroke severity (measured by the National Institutes of Health Stroke Scale) was not significantly different across the 3 groups (median, 9 [interquartile range, 2-21] for warfarin, 8 [2-20] for NOACs, and 8 [2-19] for no OACs). The unadjusted in-hospital mortality rates were 32.6% for warfarin, 26.5% for NOACs, and 22.5% for no OACs. Compared with patients without prior use of OACs, the risk of in-hospital mortality was higher among patients with prior use of warfarin (adjusted risk difference [ARD], 9.0% [97.5% CI, 7.9% to 10.1%]; adjusted odds ratio [AOR], 1.62 [97.5% CI, 1.53 to 1.71]) and higher among patients with prior use of NOACs (ARD, 3.3% [97.5% CI, 1.7% to 4.8%]; AOR, 1.21 [97.5% CI, 1.11-1.32]).

The difference in mortality between NOAC-treated patients and warfarin-treated patients was numerically greater among patients with prior use of dual antiplatelet agents (32.7% vs 47.1%; ARD, −15.0% [95.5% CI, −26.3% to −3.8%]; AOR, 0.50 [97.5% CI, 0.29 to 0.86]) than among those taking these agents without prior antiplatelet therapy (26.4% vs 31.7%; ARD, −5.0% [97.5% CI, −6.8% to −3.2%]; AOR, 0.77 [97.5% CI, 0.70 to 0.85]), although the interaction P value (.07) was not statistically significant.

[ { "docid": "5884524", "text": "BACKGROUND Although unstable coronary artery disease is the most common reason for admission to a coronary care unit, the long-term prognosis of patients with this diagnosis is unknown. This is particularly true for patients with diabetes mellitus, who are known to have a high morbidity and mortality after an acute myocardial infarction. METHODS AND RESULTS Prospectively collected data from 6 different countries in the Organization to Assess Strategies for Ischemic Syndromes (OASIS) registry were analyzed to determine the 2-year prognosis of diabetic and nondiabetic patients who were hospitalized with unstable angina or non-Q-wave myocardial infarction. Overall, 1718 of 8013 registry patients (21%) had diabetes. Diabetic patients had a higher rate of coronary bypass surgery than nondiabetic patients (23% versus 20%, P:<0.001) but had similar rates of catheterization and angioplasty. Diabetes independently predicted mortality (relative risk [RR], 1.57; 95% CI, 1.38 to 1.81; P:<0.001), as well as cardiovascular death, new myocardial infarction, stroke, and new congestive heart failure. Moreover, compared with their nondiabetic counterparts, women had a significantly higher risk than men (RR, 1.98; 95% CI, 1.60 to 2.44; and RR, 1.28; 95% CI, 1.06 to 1.56, respectively). Interestingly, diabetic patients without prior cardiovascular disease had the same event rates for all outcomes as nondiabetic patients with previous vascular disease. CONCLUSIONS Hospitalization for unstable angina or non-Q-wave myocardial infarction predicts a high 2-year morbidity and mortality; this is especially evident for patients with diabetes.

In small trials of patients undergoing surgery, graduated compression stockings (GCS) reduce the risk of DVT.

We assessed the effectiveness of thigh-length GCS to reduce DVT after stroke. METHODS In this outcome-blinded, randomised controlled trial, 2518 patients who were admitted to hospital within 1 week of an acute stroke and who were immobile were enrolled from 64 centres in the UK, Italy, and Australia. Patients were allocated via a central randomisation system to routine care plus thigh-length GCS (n=1256) or to routine care plus avoidance of GCS (n=1262). A technician who was blinded to treatment allocation undertook compression Doppler ultrasound of both legs at about 7-10 days and, when practical, again at 25-30 days after enrolment. The primary outcome was the occurrence of symptomatic or asymptomatic DVT in the popliteal or femoral veins. Analyses were by intention to treat. This study is registered, number ISRCTN28163533. FINDINGS All patients were included in the analyses. The primary outcome occurred in 126 (10.0%) patients allocated to thigh-length GCS and in 133 (10.5%) allocated to avoid GCS, resulting in a non-significant absolute reduction in risk of 0.5% (95% CI -1.9% to 2.9%).

OBJECTIVE To determine if hypoglycemic episodes severe enough to require hospitalization are associated with an increased risk of dementia in a population of older patients with type 2 diabetes followed up for 27 years. DESIGN, SETTING, AND PATIENTS A longitudinal cohort study from 1980-2007 of 16,667 patients with a mean age of 65 years and type 2 diabetes who are members of an integrated health care delivery system in northern California. MAIN OUTCOME MEASURE Hypoglycemic events from 1980-2002 were collected and reviewed using hospital discharge and emergency department diagnoses. Cohort members with no prior diagnoses of dementia, mild cognitive impairment, or general memory complaints as of January 1, 2003, were followed up for a dementia diagnosis through January 15, 2007. Dementia risk was examined using Cox proportional hazard regression models, adjusted for age, sex, race/ethnicity, education, body mass index, duration of diabetes, 7-year mean glycated hemoglobin, diabetes treatment, duration of insulin use, hyperlipidemia, hypertension, cardiovascular disease, stroke, transient cerebral ischemia, and end-stage renal disease. RESULTS At least 1 episode of hypoglycemia was diagnosed in 1465 patients (8.8%) and dementia was diagnosed in 1822 patients (11%) during follow-up; 250 patients had both dementia and at least 1 episode of hypoglycemia (16.95%). Compared with patients with no hypoglycemia, patients with single or multiple episodes had a graded increase in risk with fully adjusted hazard ratios (HRs): for 1 episode (HR, 1.26; 95% confidence interval [CI], 1.10-1.49); 2 episodes (HR, 1.80; 95% CI, 1.37-2.36); and 3 or more episodes (HR, 1.94; 95% CI, 1.42-2.64). The attributable risk of dementia between individuals with and without a history of hypoglycemia was 2.39% per year (95% CI, 1.72%-3.01%). Results were not attenuated when medical utilization rates, length of health plan membership, or time since initial diabetes diagnosis were added to the model. When examining emergency department admissions for hypoglycemia for association with risk of dementia (535 episodes), results were similar (compared with patients with 0 episodes) with fully adjusted HRs: for 1 episode (HR, 1.42; 95% CI, 1.12-1.78) and for 2 or more episodes (HR, 2.36; 95% CI, 1.57-3.55).

DOAC specific measurements were performed at trough in patients with atrial fibrillation. Patients who developed thromboembolic events showed lower DOAC plasma levels. This study supports the concept of measuring DOAC levels at steady state. SUMMARY Background Direct oral anticoagulants (DOACs) are administered at fixed doses without the need for dose adjustment according to laboratory testing. High interindividual variability in drug blood levels has been shown with all DOACs. To evaluate a possible relationship between DOAC C-trough anticoagulant levels and thromboembolic events, 565 consecutive naive patients with atrial fibrillation (AF) were enrolled in this study performed within the START Laboratory Registry. Methods DOAC-specific measurements (diluted thrombin time or anti-activated factor II calibrated for dabigatran; anti-activated FX calibrated for rivaroxaban or apixaban) at C-trough were performed locally at steady state within 15-25 days after the start of treatment. For each DOAC, the interval of C-trough levels, from the limit of quantification to the highest value, was subdivided into four equal classes, and results were attributed to these classes; the median values of results were also calculated. Thromboembolic complications occurring during 1 year of follow-up were recorded. Results Thromboembolic events (1.8%) occurred in 10 patients who had baseline C-trough levels in the lowest class of drug levels. The incidence of thromboembolic events among patients with DOAC C-trough levels in the lowest level class was 2.4%, and that in the remaining groups was 0%. The patients with thrombotic complications also had a higher mean CHA2 DS2 -VASc score than that of the total patient population: 5.3 (95% confidence interval [CI] 4.3-6.3 versus 3.0 (95% CI 2.9-3.1). Conclusion In this study cohort, thrombotic complications occurred only in DOAC-treated AF patients who had very low C-trough levels, with a relatively high CHA2 DS2 -VASc score.

However, whether it is associated with stroke prognosis has not yet been studied. Therefore, we aimed to study the association of serum soluble corin with risk of poor outcomes within 3 months after stroke. METHODS We followed 522 stroke patients for 3 months to identify major disability, death and vascular events. Serum soluble corin was measured at baseline for all participants. Logistic regression was used to examine the associations of baseline serum soluble corin with outcomes of stroke, adjusting for age, sex, baseline NIHSS score, hours from onset to hospitalization, smoking, drinking, hypertension, diabetes, coronary heart disease, atrial fibrillation, family history of stroke, and stroke subtype. RESULTS Patients with high corin had a significantly lower crude risk for the composite outcome of major disability or death (OR = 0.64, 95%CI: 0.43-0.96) than patients with low corin (the lowest tertile). After adjustment for age and baseline NIHSS score, patients with high corin still had a significantly lower risk for the composite outcome of major disability or death (OR = 0.60, 95%CI: 0.36-0.99). This association became bottom line significant after additionally adjusting for other conventional factors (OR = 0.61, P = 0.058).

In the permanent middle cerebral artery occlusion (MCAO) model of stroke, the spleen decreases in size. This reduction occurs through the release of splenic immune cells. Systemic treatment with human umbilical cord blood cells (HUCBC) 24 h post-stroke blocks the reduction in spleen size while significantly reducing infarct volume. Splenectomy 2 weeks prior to MCAO also reduces infarct volume, further demonstrating the detrimental role of this organ in stroke-induced neurodegeneration. Activation of the sympathetic nervous system after MCAO results in elevated catecholamine levels both at the level of the spleen, through direct splenic innervation, and throughout the systemic circulation upon release from the adrenal medulla. These catecholamines bind to splenic alpha and beta adrenoreceptors. This study examines whether catecholamines regulate the splenic response to stroke. Male Sprague-Dawley rats either underwent splenic denervation 2 weeks prior to MCAO or received injections of carvedilol, a pan adrenergic receptor blocker, prazosin, an alpha1 receptor blocker, or propranolol, a beta receptor blocker. Denervation was confirmed by reduced splenic expression of tyrosine hydroxylase. Denervation prior to MCAO did not alter infarct volume or spleen size. Propranolol treatment also had no effects on these outcomes. Treatment with either prazosin or carvedilol prevented the reduction in spleen size, yet only carvedilol significantly reduced infarct volume (p < 0.05).

However, little information is available on oncologists' perceptions of the risk of VTE and its management. The Fundamental Research in Oncology and Thrombosis (FRONTLINE) study is the first comprehensive global survey of thrombosis and cancer. The study was designed to collect data on the perceived risk and patterns of practice with regard to VTE in cancer patients undergoing surgical and medical management of their malignancy and to provide information on international and regional practice patterns, allowing for the design of research studies to answer the concerns of practicing clinicians. METHODS Literature reviews were performed to provide a current evidence base against which to compare the findings, and a survey was developed under the guidance of an advisory board. A paper-based reply-paid questionnaire was distributed globally between July and November 2001 to clinicians involved in cancer care and was made available on a dedicated website. FINDINGS A total of 3,891 completed responses were available for analysis. Brain and pancreatic tumors were considered to carry a high risk for VTE, and 80% of respondents considered the use of central venous lines to be associated with a high risk of VTE. Marked differences were seen in the use of thromboprophylaxis for surgical and medical cancer patients, with over 50% of surgeons reporting that they initiated thromboprophylaxis routinely, while most medical oncologists reported using thromboprophylaxis in less than 5% of medical patients. Low molecular weight heparin (LMWH) was the most popular method of thromboprophylaxis employed in both surgical and medical patients and was more favored by European than U.S. clinicians. Some 20% of respondents reported using aspirin for prophylaxis, despite there being no reliable evidence for this agent as effective in prevention in this population. For the treatment of VTE, LMWH was again the most common initial treatment, although, for the long-term, oral anticoagulation therapy was widely adopted. Many patients were treated for VTE on an outpatient basis, and secondary prevention of VTE was typically continued for 3 to 6 months after an episode of deep vein thrombosis or for longer in the case of pulmonary embolism. INTERPRETATION The results of the FRONTLINE survey demonstrate a need for guidelines to direct clinical practice in line with evidence-based data concerning cancer and VTE. Oncologists need to be educated regarding the true risks of VTE associated with certain cancers and on strategies for prevention and treatment to reduce the morbidity and mortality associated with VTE in all cancer patients.

To study the association, we designed a case-control study. METHODS Men and women 18 to 49 years of age were recruited from 43 U.S. hospitals. Eligibility criteria included the occurrence of a subarachnoid or intracerebral hemorrhage within 30 days before enrollment and the absence of a previously diagnosed brain lesion. Random-digit dialing identified two matched control subjects per patient. RESULTS There were 702 patients and 1376 control subjects. For women, the adjusted odds ratio was 16.58 (95 percent confidence interval, 1.51 to 182.21; P=0.02) for the association between the use of appetite suppressants containing phenylpropanolamine and the risk of a hemorrhagic stroke and 3.13 (95 percent confidence interval, 0.86 to 11.46; P=0.08) for the association with the first use of a product containing phenylpropanolamine. All first uses of phenylpropanolamine involved cough or cold remedies. For men and women combined, the adjusted odds ratio was 1.49 (95 percent confidence interval, 0.84 to 2.64; P=0.17) for the association between the use of a product containing phenylpropanolamine and the risk of a hemorrhagic stroke, 1.23 (95 percent confidence interval, 0.68 to 2.24; P=0.49) for the association with the use of cough or cold remedies that contained phenylpropanolamine, and 15.92 (95 percent confidence interval, 1.38 to 184.13; P=0.03) for the association with the use of appetite suppressants that contained phenylpropanolamine. An analysis in men showed no increased risk of a hemorrhagic stroke in association with the use of cough or cold remedies containing phenylpropanolamine.

Nine studies investigated the association between any migraine and ischaemic stroke (pooled relative risk 1.73, 95% confidence interval 1.31 to 2.29). Additional analyses indicated a significantly higher risk among people who had migraine with aura (2.16, 1.53 to 3.03) compared with people who had migraine without aura (1.23, 0.90 to 1.69; meta-regression for aura status P=0.02).

MAIN OUTCOME MEASURE Adjusted odds ratio (OR) of hip fracture by statin use in the 180 days and 3 years prior to the index date (the earliest date of admission for surgery), adjusted for demographic and clinical characteristics and health care utilization. RESULTS Use of statins in either the prior 180 days (adjusted OR, 0.50; 95% confidence interval [CI], 0.33-0.76) or prior 3 years (adjusted OR, 0.57; 95% CI, 0.40-0.82) was associated with a significant reduction in the risk of hip fracture, even after controlling for variables such as race, insurance status, psychoactive medications, estrogen and thiazide use, ischemic heart disease, cancer, and diabetes mellitus. No significant relationship was observed between use of nonstatin lipid-lowering agents and hip fracture risk. Clear relationships were observed between the degree of reduction in hip fracture risk and the extent of statin use; there was no evidence of such relationships with nonstatin lipid-lowering agents. After adjusting for extent of statin use in the prior 3 years, current use (on the index date) was associated with a 71% reduction in risk (adjusted OR, 0.29; 95% CI, 0.10-0.81). The relationship between statin use and hip fracture risk persisted after controlling for variables such as the number of medications, the Charlson comorbidity index score, and hospitalization or nursing home stay in the last 180 days, as well as after excluding patients who were in a nursing home prior to their index date or who died in the year after their index date. Use of nonstatin lipid-lowering agents was not observed to be associated with reduction in hip fracture risk in any of these alternative models or analyses.

Serum soluble corin and some conventional risk factors of stroke were examined. Because circulating corin was reported to be varied between men and women, the association between serum soluble corin and stroke was evaluated in men and women, respectively. RESULTS Patients with ischemic and hemorrhagic stroke had a significantly lower level of serum soluble corin than healthy controls in men and women (all P values, <0.05). In multivariate analysis, men in the lowest quartile of serum soluble corin were more likely to have ischemic (odds ratio [OR], 4.90; 95% confidence interval, 2.99-8.03) and hemorrhagic (OR, 17.57; 95% confidence interval, 4.85-63.71) stroke than men in the highest quartile. Women in the lowest quartile of serum soluble corin were also more likely to have ischemic (OR, 3.10; 95% confidence interval, 1.76-5.44) and hemorrhagic (OR, 8.54; 95% confidence interval, 2.35-31.02) stroke than women in the highest quartile. ORs of ischemic and hemorrhagic stroke were significantly increased with the decreasing levels of serum soluble corin in men and women (all P values for trend, <0.001). CONCLUSIONS Serum soluble corin was decreased in patients with stroke compared with healthy controls.

Design Prospective open cohort study. Setting General practices in England providing data for the QResearch database. Participants 1309 QResearch general practices in England: 981 practices were used to develop the scores and a separate set of 328 practices were used to validate the scores. 7.89 million patients aged 25-84 years were in the derivation cohort and 2.67 million patients in the validation cohort. Patients were free of cardiovascular disease and not prescribed statins at baseline. Methods Cox proportional hazards models in the derivation cohort to derive separate risk equations in men and women for evaluation at 10 years. Risk factors considered included those already in QRISK2 (age, ethnicity, deprivation, systolic blood pressure, body mass index, total cholesterol: high density lipoprotein cholesterol ratio, smoking, family history of coronary heart disease in a first degree relative aged less than 60 years, type 1 diabetes, type 2 diabetes, treated hypertension, rheumatoid arthritis, atrial fibrillation, chronic kidney disease (stage 4 or 5)) and new risk factors (chronic kidney disease (stage 3, 4, or 5), a measure of systolic blood pressure variability (standard deviation of repeated measures), migraine, corticosteroids, systemic lupus erythematosus (SLE), atypical antipsychotics, severe mental illness, and HIV/AIDs). We also considered erectile dysfunction diagnosis or treatment in men. Measures of calibration and discrimination were determined in the validation cohort for men and women separately and for individual subgroups by age group, ethnicity, and baseline disease status. Main outcome measures Incident cardiovascular disease recorded on any of the following three linked data sources: general practice, mortality, or hospital admission records. Results 363 565 incident cases of cardiovascular disease were identified in the derivation cohort during follow-up arising from 50.8 million person years of observation. All new risk factors considered met the model inclusion criteria except for HIV/AIDS, which was not statistically significant. The models had good calibration and high levels of explained variation and discrimination. In women, the algorithm explained 59.6% of the variation in time to diagnosis of cardiovascular disease (R2, with higher values indicating more variation), and the D statistic was 2.48 and Harrell's C statistic was 0.88 (both measures of discrimination, with higher values indicating better discrimination). The corresponding values for men were 54.8%, 2.26, and 0.86. Overall performance of the updated QRISK3 algorithms was similar to the QRISK2 algorithms. Conclusion Updated QRISK3 risk prediction models were developed and validated. The inclusion of additional clinical variables in QRISK3 (chronic kidney disease, a measure of systolic blood pressure variability (standard deviation of repeated measures), migraine, corticosteroids, SLE, atypical antipsychotics, severe mental illness, and erectile dysfunction) can help enable doctors to identify those at most risk of heart disease and stroke.", "title": "Development and validation of QRISK3 risk prediction algorithms to estimate future risk of cardiovascular disease: prospective cohort study" }, { "docid": "20554003", "text": "Anti-inflammatory therapy decreases infarct size and enhances stroke recovery.

The Trial to Assess Improvement in Therapeutic Outcomes by Optimizing Platelet Inhibition With Prasugrel-Thrombolysis in Myocardial Infarction 38 (TRITON-TIMI 38) showed an overall reduction in ischemic events with more intensive antiplatelet therapy with prasugrel than with clopidogrel but with more bleeding. We compared prasugrel with clopidogrel among subjects with DM in TRITON-TIMI 38. METHODS AND RESULTS We classified 13 608 subjects on the basis of preexisting history of DM and further according to insulin use. Prespecified analyses of the primary (cardiovascular death, nonfatal myocardial infarction, or nonfatal stroke) and key secondary end points, including net clinical benefit (death, nonfatal myocardial infarction, nonfatal stroke, and nonfatal TIMI major bleeding) were compared by use of the log-rank test. We found that 3146 subjects had a preexisting history of DM, including 776 receiving insulin. The primary end point was reduced significantly with prasugrel among subjects without DM (9.2% versus 10.6%; hazard ratio [HR], 0.86; P=0.02) and with DM (12.2% versus 17.0%; HR, 0.70; P<0.001, P(interaction)=0.09). A benefit for prasugrel was observed among DM subjects on insulin (14.3% versus 22.2%; HR, 0.63; P=0.009) and those not on insulin (11.5% versus 15.3%; HR, 0.74; P=0.009). Myocardial infarction was reduced with prasugrel by 18% among subjects without DM (7.2% versus 8.7%; HR, 0.82; P=0.006) and by 40% among subjects with DM (8.2% versus 13.2%; HR, 0.60; P<0.001, P(interaction)=0.02). Although TIMI major hemorrhage was increased among subjects without DM on prasugrel (1.6% versus 2.4%; HR, 1.43; P=0.02), the rates were similar among subjects with DM for clopidogrel and prasugrel (2.6% versus 2.5%; HR, 1.06; P=0.81, P(interaction)=0.29).

CONCLUSIONS Subjects with DM tended to have a greater reduction in ischemic events without an observed increase in TIMI major bleeding and therefore a greater net treatment benefit with prasugrel compared with clopidogrel.

DESIGN Cohort study of people aged 65 and over diagnosed as having depression. SETTING 570 general practices in the United Kingdom supplying data to the QResearch primary care database. PARTICIPANTS 60,746 patients diagnosed as having a new episode of depression between the ages of 65 and 100 years from 1 January 1996 to 31 December 2007 and followed up until 31 December 2008. MAIN OUTCOME MEASURES Hazard ratios associated with antidepressant use for all cause mortality, attempted suicide/self harm, myocardial infarction, stroke/transient ischaemic attack, falls, fractures, upper gastrointestinal bleeding, epilepsy/seizures, road traffic accidents, adverse drug reactions, and hyponatraemia, adjusted for a range of potential confounding variables. Hazard ratios were calculated for antidepressant class (tricyclic and related antidepressants, selective serotonin reuptake inhibitors, other antidepressants), dose, and duration of use and for commonly prescribed individual drugs. RESULTS 54,038 (89.0%) patients received at least one prescription for an antidepressant during follow-up. A total of 1,398,359 antidepressant prescriptions were issued: 764,659 (54.7%) for selective serotonin reuptake inhibitors, 442,192 (31.6%) for tricyclic antidepressants, 2203 (0.2%) for monoamine oxidase inhibitors, and 189,305 (13.5%) for the group of other antidepressants. The associations with the adverse outcomes differed significantly between the antidepressant classes for seven outcomes. Selective serotonin reuptake inhibitors were associated with the highest adjusted hazard ratios for falls (1.66, 95% confidence interval 1.58 to 1.73) and hyponatraemia (1.52, 1.33 to 1.75) compared with when antidepressants were not being used. The group of other antidepressants was associated with the highest adjusted hazard ratios for all cause mortality (1.66, 1.56 to 1.77), attempted suicide/self harm (5.16, 3.90 to 6.83), stroke/transient ischaemic attack (1.37, 1.22 to 1.55), fracture (1.64, 1.46 to 1.84), and epilepsy/seizures (2.24, 1.60 to 3.15), compared with when antidepressants were not being used. Tricyclic antidepressants did not have the highest hazard ratio for any of the outcomes. Significantly different associations also existed between the individual drugs for the same seven outcomes; trazodone (tricyclic antidepressant), mirtazapine, and venlafaxine (both in the group of other antidepressants) were associated with the highest rates for some of these outcomes. Absolute risks over 1 year for all cause mortality were 7.04% for patients while not taking antidepressants, 8.12% for those taking tricyclic antidepressants, 10.61% for selective serotonin reuptake inhibitors, and 11.43% for other antidepressants. CONCLUSIONS Selective serotonin reuptake inhibitors and drugs in the group of other antidepressants were associated with an increased risk of several adverse outcomes compared with tricyclic antidepressants. Among individual drugs, trazodone, mirtazapine, and venlafaxine were associated with the highest risks for some outcomes. As this is an observational study, it is susceptible to confounding by indication, channelling bias, and residual confounding, so differences in characteristics between patients prescribed different antidepressant drugs that could account for some of the associations between the drugs and the adverse outcomes may remain.

METHOD The retrospective, cohort study used national data from the Department of Veterans Affairs (fiscal years 2001-2005) on patients older than 65 years who began outpatient treatment with psychiatric medication following a dementia diagnosis (N=10,615). Twelve-month mortality rates were compared in patients taking antipsychotics and those taking other psychiatric medications. The authors controlled for confounding by using multivariate models and propensity-scoring methods. Secondary analyses included a no-medication group and examination of mortality causes. RESULTS All groups taking antipsychotics had significantly higher mortality rates (22.6%-29.1%) than patients taking nonantipsychotic medications (14.6%). Adjusted mortality risks for atypicals and for combined atypical and conventional antipsychotics were similar to those for conventional antipsychotics. The mortality risk was significantly lower for nonantipsychotic medications than conventional antipsychotics. Except for anticonvulsants, the adjusted risks for all individual classes of nonantipsychotics were significantly lower than the risk for antipsychotics. Mortality risks did not change over 12 months. The proportions of patients taking antipsychotics who died from cerebrovascular, cardiovascular, or infectious causes were not higher than rates for those taking nonantipsychotic psychiatric medications. CONCLUSIONS Antipsychotic medications taken by patients with dementia were associated with higher mortality rates than were most other medications used for neuropsychiatric symptoms.

The mean age was 75 years (SD 7), and 936 (47 %) subjects were male. The in-hospital mortality rate was 3.76 % (74 patients).

Multivariate logistic analysis showed that RDW was associated with all-cause in-hospital mortality after adjusting for other confounding factors. DISCUSSION RDW value at admission is an independent predictor of all-cause in-hospital mortality among patients older than 65 years. After adjustment for multiple confounders, the all-cause in-hospital mortality rate increased by 21.8% for each 1% increase in RDW.

BACKGROUND Although prior evidence suggests an independent association between female gender and preserved left ventricular systolic function (LVSF) in patients with HF, existing studies are limited by referral biases, small sample sizes, or the inability to adjust for a wide range of potential confounding variables. METHODS This is a cross-sectional study using data from retrospective medical chart abstraction of a national sample of Medicare beneficiaries hospitalized with the principal discharge diagnosis of HF in acute-care nongovernmental hospitals in the U.S. between April 1998 and March 1999. Patients were eligible for this analysis if they were age 65 years or older, had documentation of LVSF, and corroboration of the diagnosis of HF. We used multivariable logistic regression to identify the correlates of preserved LVSF, which was defined as qualitatively normal function or quantitatively reported ejection fraction > or =0.50. Stratified regressions by gender were performed to identify significant interactions. RESULTS Of the 19,710 patients in the analysis, preserved LVSF was present in 6,700 (35%), 79% of whom were women. In contrast, among the 12,956 patients with impaired LVSF, only 49% were women. Patients with preserved LVSF were 1.5 years older than those with impaired LVSF. After adjustment for age and other patient factors, female gender remained strongly associated with preserved LVSF (calculated risk ratio = 1.71; 95% confidence interval 1.63 to 1.78). The association was consistent in all age groups, and was similar in patients with or without coronary artery disease, hypertension, pulmonary disease, renal insufficiency, or atrial fibrillation.

[ { "docid": "23397658", "text": "Fibroblast growth factor 21 (FGF21), a metabolic hormone predominantly produced by the liver, is also expressed in adipocytes and the pancreas. It regulates glucose and lipid metabolism through pleiotropic actions in these tissues and the brain. In mice, fasting leads to increased PPAR-α mediated expression of FGF21 in the liver where it stimulates gluconeogenesis, fatty acid oxidation, and ketogenesis, as an adaptive response to fasting and starvation. In the fed state, FGF21 acts as an autocrine factor in adipocytes, regulating the activity of PPAR-γ through a feed-forward loop mechanism. Administration of recombinant FGF21 has been shown to confer multiple metabolic benefits on insulin sensitivity, blood glucose, lipid profile and body weight in obese mice and diabetic monkeys, without mitogenic or other side effects. Such findings highlight the potential role of FGF21 as a therapeutic agent for obesity-related medical conditions. However, in human studies, high circulating FGF21 levels are found in obesity and its related cardiometabolic disorders including the metabolic syndrome, type 2 diabetes, non-alcoholic fatty liver disease and coronary artery disease. These findings may indicate the presence of FGF21 resistance or compensatory responses to the underlying metabolic stress, and imply the need for supraphysiological doses of FGF21 to achieve therapeutic efficacy. On the other hand, serum FGF21 has been implicated as a potential biomarker for the early detection of these cardiometabolic disorders.

The mechanisms that regulate energy balance have substantial built-in redundancy, overlap considerably with other physiological functions, and are influenced by social, hedonic and psychological factors that limit the effectiveness of pharmacological interventions. It is therefore unsurprising that anti-obesity drug discovery programmes have been littered with false starts, failures in clinical development, and withdrawals due to adverse effects that were not fully appreciated at the time of launch. Drugs that target pathways in metabolic tissues, such as adipocytes, liver and skeletal muscle, have shown potential in preclinical studies but none has yet reached clinical development. Recent improvements in the understanding of peptidergic signalling of hunger and satiety from the gastrointestinal tract mediated by ghrelin, cholecystokinin (CCK), peptide YY (PYY) and glucagon-like peptide-1 (GLP-1), and of homeostatic mechanisms related to leptin and its upstream pathways in the hypothalamus, have opened up new possibilities. Although some have now reached clinical development, it is uncertain whether they will meet the strict regulatory hurdles required for licensing of an anti-obesity drug. However, GLP-1 receptor agonists have already succeeded in diabetes treatment and, owing to their attractive body-weight-lowering effects in humans, will perhaps also pave the way for other anti-obesity agents. To succeed in developing drugs that control body weight to the extent seen following surgical intervention, it seems obvious that a new paradigm is needed. In other therapeutic arenas, such as diabetes and hypertension, lower doses of multiple agents targeting different pathways often yield better results than strategies that modify one pathway alone. Some combination approaches using peptides and small molecules have now reached clinical trials, although recent regulatory experience suggests that large challenges lie ahead.

Although this has often been cited as a potential quality-of-care problem, reviews of research evidence on antipsychotic polypharmacy have not distinguished between appropriate versus inappropriate use. METHODS A MEDLINE search from 1966 to December 2007 was completed to identify studies comparing changes in symptoms, functioning, and/or side effects between patients treated with multiple antipsychotics and patients treated with a single antipsychotic. The studies were reviewed in two groups on the basis of whether prescribing was concordant with guideline recommendations for multiple-antipsychotic use. RESULTS A review of the literature, including three randomized controlled trials, found no support for the use of antipsychotic polypharmacy in patients without an established history of treatment resistance to multiple trials of monotherapy. In patients with a history of treatment resistance to multiple monotherapy trials, limited data support antipsychotic polypharmacy, but positive outcomes were primarily found in studies of clozapine augmented with a second-generation antipsychotic. DISCUSSION Research evidence is consistent with the goal of avoiding antipsychotic polypharmacy in patients who lack guideline-recommended indications for its use.

Binge eating behaviors have been linked to poorer outcomes among bariatric surgery patients, and binge eating disorder have be considered a contraindication in surgery programs, some of which have mandated preoperative binge eating treatment. However, no previous studies have examined whether a preoperative binge eating intervention could successfully reduce binge eating behaviors among severely obese bariatric surgery candidates. METHODS A total of 243 bariatric surgery candidates completed a brief cognitive behavioral group treatment for binge eating behaviors and were administered the Binge Eating Scale and reported the number of weekly binge eating episodes at the initial psychological evaluation and again after the group sessions. The study used a pre-post intervention design.

OBJECTIVE To determine if surgically induced weight loss results in better glycemic control and less need for diabetes medications than conventional approaches to weight loss and diabetes control. DESIGN, SETTING, AND PARTICIPANTS Unblinded randomized controlled trial conducted from December 2002 through December 2006 at the University Obesity Research Center in Australia, with general community recruitment to established treatment programs. Participants were 60 obese patients (BMI >30 and <40) with recently diagnosed (<2 years) type 2 diabetes. INTERVENTIONS Conventional diabetes therapy with a focus on weight loss by lifestyle change vs laparoscopic adjustable gastric banding with conventional diabetes care. MAIN OUTCOME MEASURES Remission of type 2 diabetes (fasting glucose level <126 mg/dL [7.0 mmol/L] and glycated hemoglobin [HbA1c] value <6.2% while taking no glycemic therapy). Secondary measures included weight and components of the metabolic syndrome. Analysis was by intention-to-treat. RESULTS Of the 60 patients enrolled, 55 (92%) completed the 2-year follow-up. Remission of type 2 diabetes was achieved by 22 (73%) in the surgical group and 4 (13%) in the conventional-therapy group. Relative risk of remission for the surgical group was 5.5 (95% confidence interval, 2.2-14.0). Surgical and conventional-therapy groups lost a mean (SD) of 20.7% (8.6%) and 1.7% (5.2%) of weight, respectively, at 2 years (P < .001). Remission of type 2 diabetes was related to weight loss (R2 = 0.46, P < .001) and lower baseline HbA1c levels (combined R2 = 0.52, P < .001). There were no serious complications in either group. CONCLUSIONS Participants randomized to surgical therapy were more likely to achieve remission of type 2 diabetes through greater weight loss.

OBJECTIVE To conduct a systematic review of behavioral counseling for overweight and obese patients recruited from primary care, as delivered by primary care practitioners working alone or with trained interventionists (eg, medical assistants, registered dietitians), or by trained interventionists working independently. EVIDENCE REVIEW We searched PubMed, CINAHL, and EMBASE for randomized controlled trials published between January 1980 and June 2014 that recruited overweight and obese patients from primary care; provided behavioral counseling (ie, diet, exercise, and behavioral therapy) for at least 3 months, with at least 6 months of postrandomization follow-up; included at least 15 participants per treatment group and objectively measured weights; and had a comparator, an intention-to-treat analysis, and attrition of less than 30% at 1 year or less than 40% at longer follow-up. FINDINGS Review of 3304 abstracts yielded 12 trials, involving 3893 participants, that met inclusion-exclusion criteria and prespecified quality ratings. No studies were found in which primary care practitioners delivered counseling that followed the CMS guidelines. Mean 6-month weight changes from baseline in the intervention groups ranged from a loss of 0.3 kg to 6.6 kg. In the control group, mean change ranged from a gain of 0.9 kg to a loss of 2.0 kg. Weight loss in both groups generally declined with longer follow-up (12-24 months). Interventions that prescribed both reduced energy intake (eg, ≥ 500 kcal/d) and increased physical activity (eg, ≥150 minutes a week of walking), with traditional behavioral therapy, generally produced larger weight loss than interventions without all 3 specific components. In the former trials, more treatment sessions, delivered in person or by telephone by trained interventionists, were associated with greater mean weight loss and likelihood of patients losing 5% or more of baseline weight. CONCLUSIONS AND RELEVANCE Intensive behavioral counseling can induce clinically meaningful weight loss, but there is little research on primary care practitioners providing such care.

The need for multiple doses produces problems with medication administration during school and after-school hours, and therefore with compliance. Previous long-acting stimulants and preparations have shown effects equivalent to twice-daily dosing of MPH. This study tests the efficacy and duration of action, in natural and laboratory settings, of an extended-release MPH preparation designed to last 12 hours and therefore be equivalent to 3-times-daily dosing. METHODS Sixty-eight children with ADHD, 6 to 12 years old, participated in a within-subject, double-blind comparison of placebo, immediate-release (IR) MPH 3 times a day (tid), and Concerta, a once-daily MPH formulation. Three dosing levels of medication were used: 5 mg IR MPH tid/18 mg Concerta once a day (qd); 10 mg IR MPH tid/36 mg Concerta qd; and 15 mg IR MPH tid/54 mg Concerta qd. All children were currently medicated with MPH at enrollment, and each child's dose level was based on that child's MPH dosing before the study. The doses of Concerta were selected to be comparable to the daily doses of MPH that each child received. To achieve the ascending rate of MPH delivery determined by initial investigations to provide the necessary continuous coverage, Concerta doses were 20% higher on a daily basis than a comparable tid regimen of IR MPH. Children received each medication condition for 7 days. The investigation was conducted in the context of a background clinical behavioral intervention in both the natural environment and the laboratory setting. Parents received behavioral parent training and teachers were taught to establish a school-home daily report card (DRC). A DRC is a list of individual target behaviors that represent a child's most salient areas of impairment. Teachers set daily goals for each child's impairment targets, and parents provided rewards at home for goal attainment. Each weekday, teachers completed the DRC, and it was used as a dependent measure of individualized medication response. Teachers and parents also completed weekly standardized ratings of behavior and treatment effectiveness. To evaluate the time course of medication effects, children spent 12 hours in a laboratory setting on Saturdays and medication effects were measured using procedures and methods adapted from our summer treatment program. Measures of classroom behavior and academic productivity/accuracy were taken in a laboratory classroom setting during which children completed independent math and reading worksheets. Measures of social behavior were taken in structured, small-group board game settings and unstructured recess settings. Measures included behavior frequency counts, academic problems completed and accuracy, independent observations, teacher and counselor ratings, and individualized behavioral target goals. Reports of adverse events, sleep quality, and appetite were collected. RESULTS On virtually all measures in all settings, both drug conditions were significantly different from placebo, and the 2 drugs were not different from each other. In children's regular school settings, both medications improved behavior as measured by teacher ratings and individualized target behaviors (the DRC); these effects were seen into the evening as measured by parent ratings. In the laboratory setting, effects of Concerta were equivalent to tid MPH and lasted at least through 12 hours after dosing. Concerta was significantly superior to tid MPH on 2 parent rating scores, and when asked, more parents preferred Concerta than preferred tid IR MPH or placebo. Side effects on children's sleep and appetite were similar for the 2 preparations. In the lab setting, both medications improved productivity and accuracy on arithmetic seatwork assignments, disruptive and on-task behavior, and classroom rule following. Both medications improved children's rule following and negative behavior in small group board games, as well as in unstructured recess settings. Individual target behaviors also showed significant improvement with medication across domains in the laboratory setting. Children's behavior across settings deteriorated across the laboratory day, and the primary effect of medication was to prevent this deterioration as the day wore on. Results support the use of background behavioral treatment in clinical trials of stimulant medication, and illustrate the utility of a measure of individualized daily target goals (ie, the DRC) as an objective measure of medication response in both the laboratory and natural school settings. CONCLUSION This investigation clearly supports the efficacy of the Concerta long-acting formulation of MPH for parents who desire to have medication benefits for their child throughout the day and early evening.

Cytokines are important for development and normal brain function, and have the ability to influence neurocircuitry and neurotransmitter systems to produce behavioral alterations. Acutely, inflammatory cytokine administration or activation of the innate immune system produces adaptive behavioral responses that promote conservation of energy to combat infection or recovery from injury. However, chronic exposure to elevated inflammatory cytokines and persistent alterations in neurotransmitter systems can lead to neuropsychiatric disorders and depression. Mechanisms of cytokine behavioral effects involve activation of inflammatory signaling pathways in the brain that results in changes in monoamine, glutamate, and neuropeptide systems, and decreases in growth factors, such as brain-derived neurotrophic factor. Furthermore, inflammatory cytokines may serve as mediators of both environmental (e.g. childhood trauma, obesity, stress, and poor sleep) and genetic (functional gene polymorphisms) factors that contribute to depression's development.

Women reporting use of exogenous estrogens or oral contraceptives within 6 months of interview were excluded, resulting in 68 case patients and 107 control subjects among premenopausal women and 208 case patients and 209 control subjects among postmenopausal women. The hormone analyses were performed on blood samples obtained from case patients or from hysterectomy control subjects before surgery. The odds ratios (ORs) and 95% confidence intervals (CIs) were estimated by use of an unconditional logistic regression analysis after we controlled for matching variables and potential confounders. All P values were two-sided. RESULTS High circulating levels of androstenedione were associated with 3.6-fold and 2.8-fold increased risks among premenopausal and postmenopausal women, respectively, after adjustment for other factors (P for trend = .01 and < .001, respectively). Risks related to other hormone fractions varied by menopausal status. Among postmenopausal women, a reduced risk was associated with high SHBG levels and persisted after adjustment was made for obesity and other factors (OR = 0.51; 95% CI = 0.27-0.95). High estrone levels were associated with increased risk (OR = 3.8; 95% CI = 2.2-6.6), although adjustment for other risk factors (particularly body mass index) diminished the effect (OR = 2.2; 95% CI = 1.2-4.4). Albumin-bound estradiol (E2), a marker of the bioavailable fraction, also remained an important risk factor after adjustment was made for other factors (OR = 2.0; 95% CI = 1.0-3.9). In contrast, high concentrations of total, free, and albumin-bound E2 were unrelated to increased risk in premenopausal women. In both premenopausal and postmenopausal groups, risks associated with obesity and fat distribution were not affected by adjustment for hormones. CONCLUSION High endogenous levels of unopposed estrogen are related to increased risk of endometrial cancer, but their independence from other risk factors is inconsistent with being a common underlying biologic pathway through which all risk factors for endometrial cancer operate. IMPLICATIONS Further research should focus on alternative endocrinologic mechanisms for risk associated with obesity and body fat distribution and for the biologic relevance of the increased risk associated with androstenedione in both premenopausal and postmenopausal disease.", "title": "Case-control study of endogenous steroid hormones and endometrial cancer." }, { "docid": "31562330", "text": "BACKGROUND The increased caloric requirements of HIV-positive individuals, undesirable side effects of treatment that may be worsened by malnutrition (but alleviated by nutritional support), and associated declines in adherence and possible increased drug resistance are all justifications for developing better interventions to strengthen the nutrition security of individuals receiving antiretroviral treatment. OBJECTIVE To highlight key benefits and challenges relating to interventions aimed at strengthening the nutrition security of people living with HIV who are receiving antiretroviral treatment. METHODS Qualitative research was undertaken on a short-term nutrition intervention linked to the provision of free antiretroviral treatment for people living with HIV in western Kenya in late 2005 and early 2006. RESULTS Patients enrolled in the food program while on treatment regimens self-reported greater adherence to their medication, fewer side effects, and a greater ability to satisfy increased appetite. Most clients self-reported weight gain, recovery of physical strength, and the resumption of labor activities while enrolled in dual (food supplementation and treatment) programs. Such improvements were seen to catalyze increased support from family and community. CONCLUSIONS These findings provide further empirical support to calls for a more holistic and comprehensive response to the coexistence of AIDS epidemics with chronic nutrition insecurity. Future work is needed to clarify ways of bridging the gap between short-term nutritional support to individuals and longer-term livelihood security programming for communities affected by AIDS. Such interdisciplinary research will need to be matched by intersectoral action on the part of the agriculture and health sectors in such environments.", "title": "Integrating nutrition security with treatment of people living with HIV: lessons from Kenya." }, { "docid": "13441037", "text": "In this review, we address the natural history of obesity in children, the most promising family- and school-based approaches to the prevention of obesity, and the barriers and opportunities associated with secondary prevention. In childhood, the most important periods of risk appear to be the periods of adiposity rebound and adolescence. Caution regarding the period of adiposity rebound is still warranted, because it is not yet clear that early rebound is attributable to changes in body fat. Families and schools represent the most important foci for preventive efforts in children and adolescents. One productive approach is to proceed from an examination of factors that affect energy balance to the identification of more proximal influences on those factors. This approach may help to narrow the strategies necessary to prevent or treat childhood obesity. For example, television viewing affects both energy intake and energy expenditure, and therefore represents a logical target for interventions. Anticipatory guidance by pediatricians may offer an effective mechanism by which to change parental attitudes and practices regarding television viewing. A similar process is used to emphasize the potential influence of school-based interventions directed at changes in food choices and sedentary behavior.", "title": "Preventing obesity in children and adolescents." }, { "docid": "13001323", "text": "Chronic feeding on high-calorie diets causes obesity and type 2 diabetes mellitus (T2DM), illnesses that affect hundreds of millions.

Also, mutant mice have increased susceptibility to developing dietary T2DM due to insulin resistance in skeletal muscle. Mechanistically, these aberrations arise, in part, from impaired metabolic actions of the neuropeptide orexin-A and the hormone leptin.

The use of aminorex, an amphetamine analog that increases norepinephrine levels in the central nervous system, led to an epidemic of primary pulmonary hypertension (PPH) in Europe in the late 1960s and early 1970s. The use of fenfluramine and later dexfenfluramine [drugs that inhibit 5-hydroxytryptamine (5-HT) release and reuptake and increases 5-HT and thus 5-HT secretion in the brain] was associated with a second epidemic of PPH. All of these drugs have been voluntarily withdrawn from the market. The pathogenesis of PPH in patients treated with these agents is uncertain, but recent evidence suggests that potassium channel abnormalities and vasoactive and proliferative properties of 5-HT may play a role. There is increasing experimental evidence suggesting that aminorex, fenfluramine and dexfenfluramine inhibit 4-aminopyridine-sensitive currents in potassium channels resulting in vasoconstriction in pulmonary resistance vessels and perhaps smooth muscle cell proliferation. 5-HT causes pulmonary artery vasoconstriction and smooth muscle cell proliferation. Its levels are known to be high in those with fenfluramine-induced PPH. However, a firm cause-and-effect relationship has not yet been established.

OBJECTIVE To assess the evidence for increased mortality from atypical antipsychotic drug treatment for people with dementia. DATA SOURCES MEDLINE (1966 to April 2005), the Cochrane Controlled Trials Register (2005, Issue 1), meetings presentations (1997-2004), and information from the sponsors were searched using the terms for atypical antipsychotic drugs (aripiprazole, clozapine, olanzapine, quetiapine, risperidone, and ziprasidone), dementia, Alzheimer disease, and clinical trial. STUDY SELECTION Published and unpublished randomized placebo-controlled, parallel-group clinical trials of atypical antipsychotic drugs marketed in the United States to treat patients with Alzheimer disease or dementia were selected by consensus of the authors. DATA EXTRACTION Trials, baseline characteristics, outcomes, all-cause dropouts, and deaths were extracted by one reviewer; treatment exposure was obtained or estimated. Data were checked by a second reviewer. DATA SYNTHESIS Fifteen trials (9 unpublished), generally 10 to 12 weeks in duration, including 16 contrasts of atypical antipsychotic drugs with placebo met criteria (aripiprazole [n = 3], olanzapine [n = 5], quetiapine [n = 3], risperidone [n = 5]). A total of 3353 patients were randomized to study drug and 1757 were randomized to placebo. Outcomes were assessed using standard methods (with random- or fixed-effects models) to calculate odds ratios (ORs) and risk differences based on patients randomized and relative risks based on total exposure to treatment. There were no differences in dropouts. Death occurred more often among patients randomized to drugs (118 [3.5%] vs 40 [2.3%]. The OR by meta-analysis was 1.54; 95% confidence interval [CI], 1.06-2.23; P = .02; and risk difference was 0.01; 95% CI, 0.004-0.02; P = .01).

Activation of glucagon-like peptide-1 (GLP-1) signalling ameliorates detrimental effects of obesity-diabetes on cognitive function; however, mechanisms underlying these beneficial actions remain unclear. This study examined effects of daily subcutaneous treatment with GLP-1 mimetic, Liraglutide, on synaptic plasticity, hippocampal gene expression and metabolic control in adult obese diabetic (ob/ob) mice. Results:Long-term potentiation (LTP) induced by area CA1 was completely abolished in ob/ob mice compared with lean controls. Deleterious effects on LTP were rescued (P<0.001) with Liraglutide. Indeed, Liraglutide-treated mice exhibited superior LTP profile compared with lean controls (P<0.01). Expression of hippocampal brain-derived neurotropic factor and neurotrophic tyrosine kinase receptor-type 2 were not significantly different, but synaptophysin and Mash1 were decreased in ob/ob mice. Treatment with Liraglutide over 21 days increased expression of Mash1 in ob/ob mice (2.0-fold; P<0.01). These changes were associated with significantly reduced plasma glucose (21% reduction; P<0.05) and markedly improved plasma insulin concentrations (2.1- to 3.3-fold; P<0.05 to P<0.01). Liraglutide also significantly reduced the glycaemic excursion following an intraperitonal glucose load (area under curve (AUC) values: 22%; P<0.05) and markedly enhanced the insulin response to glucose (AUC values: 1.6-fold; P<0.05). O2 consumption, CO2 production, respiratory exchange ratio and energy expenditure were not altered by Liraglutide therapy. On day 21, accumulated food intake (32% reduction; P<0.05) and number of feeding bouts (32% reduction; P<0.05) were significantly reduced but simple energy restriction was not responsible for the beneficial actions of Liraglutide.

DESIGN AND SETTING Randomized placebo-controlled trial conducted from August 1995 to January 1998 at 2 outpatient sites in Ohio. PARTICIPANTS Two hundred three adults (mean age, 37 years; 76% women) with diagnosis of chronic tension-type headaches (mean, 26 headache d/mo). INTERVENTIONS Participants were randomly assigned to receive tricyclic antidepressant (amitriptyline hydrochloride, up to 100 mg/d, or nortriptyline hydrochloride, up to 75 mg/d) medication (n = 53), placebo (n = 48), stress management (eg, relaxation, cognitive coping) therapy (3 sessions and 2 telephone contacts) plus placebo (n = 49), or stress management therapy plus antidepressant medication (n = 53). MAIN OUTCOME MEASURES Monthly headache index scores calculated as the mean of pain ratings (0-10 scale) recorded by participants in a daily diary 4 times per day; number of days per month with at least moderate pain (pain rating >/=5), analgesic medication use, and Headache Disability Inventory scores, compared by intervention group. RESULTS Tricyclic antidepressant medication and stress management therapy each produced larger reductions in headache activity, analgesic medication use, and headache-related disability than placebo, but antidepressant medication yielded more rapid improvements in headache activity. Combined therapy was more likely to produce clinically significant (>/=50%) reductions in headache index scores (64% of participants) than antidepressant medication (38% of participants; P =.006), stress management therapy (35%; P =.003), or placebo (29%; P =.001).

Henry VIII of England had a war with someone.
[ { "docid": "Henry_VIII_of_England", "text": "Henry VIII ( 28 June 1491 -- 28 January 1547 ) was King of England from 21 April 1509 until his death . Henry was the second Tudor monarch , succeeding his father , Henry VII . Henry is best known for his six marriages and , in particular , his efforts to have his first marriage , to Catherine of Aragon , annulled . His disagreement with the Pope on the question of such an annulment led Henry to initiate the English Reformation , separating the Church of England from papal authority and appointing himself the Supreme Head of the Church of England . Despite his resulting excommunication , Henry remained a believer in core Catholic theological teachings . Domestically , Henry is known for his radical changes to the English Constitution , ushering in the theory of the divine right of kings to England . Besides asserting the sovereign 's supremacy over the Church of England , he greatly expanded royal power during his reign . Charges of treason and heresy were commonly used to quash dissent , and those accused were often executed without a formal trial , by means of bills of attainder . He achieved many of his political aims through the work of his chief ministers , some of whom were banished or executed when they fell out of his favour . Thomas Wolsey , Thomas More , Thomas Cromwell , Richard Rich , and Thomas Cranmer all figured prominently in Henry 's administration . He was an extravagant spender and used the proceeds from the Dissolution of the Monasteries and acts of the Reformation Parliament to convert into royal revenue the money that was formerly paid to Rome . Despite the influx of money from these sources , Henry was continually on the verge of financial ruin due to his personal extravagance as well as his numerous costly continental wars , particularly with Francis I of France and the Holy Roman Emperor Charles V , as he sought to enforce his claim to the Kingdom of France . At home , he oversaw the legal union of England and Wales with the Laws in Wales Acts 1535 and 1542 and following the Crown of Ireland Act 1542 he was the first English monarch to rule as King of Ireland . His contemporaries considered Henry in his prime to be an attractive , educated , and accomplished king , and he has been described as `` one of the most charismatic rulers to sit on the English throne '' . He was an author and composer . As he aged , Henry became severely obese and his health suffered , contributing to his death in 1547 . He is frequently characterised in his later life as a lustful , egotistical , harsh , and insecure king . He was succeeded by his son Edward VI .", "title": "" } ]

It is doubtful that England intended to invade Scotland , since Henry VIII made no move to take advantage of his comprehensive victory at the 1542 Battle of Solway Moss and the subsequent death of James V of Scotland ( who left his infant daughter as heir . ) Instead , it is likely that Henry VIII intended merely to weaken Scotland and arrange a marriage alliance with Mary , Queen of Scots , whilst refocusing the bulk of his forces upon a speculative invasion of France . War was declared by Henry VIII in an attempt to force the Scots to agree to a marriage between his son Edward and the infant Mary , Queen of Scots , thereby creating a new alliance between Scotland and England .

Her daughter Elizabeth would later succeed Henry VIII as Elizabeth I , Queen of England and Ireland . Anne was the daughter of Thomas Boleyn , 1st Earl of Wiltshire , and his wife , Lady Elizabeth Howard , and was educated in the Netherlands and France , largely as a maid of honour to Claude of France . Anne returned to England in early 1522 , to marry her Irish cousin James Butler , 9th Earl of Ormond ; the marriage plans were broken up by Cardinal Wolsey , and instead she secured a post at court as maid of honour to Henry VIII 's wife , Catherine of Aragon . Early in 1523 Anne was secretly betrothed to Henry Percy , son of the 5th Earl of Northumberland , but the betrothal was broken by Cardinal Wolsey in January 1524 and Anne was sent back home to Hever Castle . In February/March 1526 , Henry VIII began his pursuit of Anne . She resisted his attempts to seduce her , refusing to become his mistress -- which her sister Mary had been . It soon became the one absorbing object of Henry 's desires to annul his marriage to Queen Catherine so he would be free to marry Anne . When it became clear that Pope Clement VII would not annul the marriage , the breaking of the power of the Catholic Church in England began . In 1532 , Henry granted Anne the Marquessate of Pembroke . Henry and Anne married on 25 January 1533 , after a secret marriage on 14 November 1532 . On 23 May 1533 , newly appointed Archbishop of Canterbury Thomas Cranmer declared Henry and Catherine 's marriage null and void ; five days later , he declared Henry and Anne 's marriage valid . Shortly afterwards , the Pope decreed sentences of excommunication against Henry and Cranmer . As a result of this marriage and these excommunications , the first break between the Church of England and Rome took place and the Church of England was brought under the King 's control . Anne was crowned Queen of England on 1 June 1533 . On 7 September , she gave birth to the future Queen Elizabeth I. Henry was disappointed to have a daughter rather than a son but hoped a son would follow and professed to love Elizabeth . Anne subsequently had three miscarriages , and by March 1536 , Henry was courting Jane Seymour . In order to marry Jane Seymour , Henry had to find reasons for his marriage with Anne to end . Henry had Anne investigated for high treason in April 1536 . On 2 May she was arrested and sent to the Tower of London , where she was tried before a jury of peers -- which included Henry Percy , her former betrothed , and her own uncle , Thomas Howard -- and found guilty on 15 May . She was beheaded four days later . Modern historians view the charges against her , which included adultery , incest , and plotting to kill the king , as unconvincing . Some say that Anne was accused of witchcraft but the indictments make no mention of this charge . After the coronation of her daughter , Elizabeth , as queen , Anne was venerated as a martyr and heroine of the English Reformation , particularly through the works of John Foxe . Over the centuries , she has inspired , or been mentioned , in many artistic and cultural works and thereby retained her hold on the popular imagination .

During his reign , the realm was governed by a Regency Council because he never reached his majority . The Council was first led by his uncle Edward Seymour , 1st Duke of Somerset ( 1547 -- 1549 ) , and then by John Dudley , 1st Earl of Warwick , from 1551 Duke of Northumberland . Edward 's reign was marked by economic problems and social unrest that , in 1549 , erupted into riot and rebellion .

His victory was reinforced by his marriage to Elizabeth of York , daughter of King Edward IV , symbolically uniting the former warring factions under a new dynasty . The Tudors extended their power beyond modern England , achieving the full union of England and the Principality of Wales in 1542 ( Laws in Wales Acts 1535 and 1542 ) , and successfully asserting English authority over the Kingdom of Ireland . They also maintained the nominal English claim to the Kingdom of France ; although none of them made substance of it , Henry VIII fought wars with France trying to reclaim that title . After him , his daughter Mary I lost control of all territory in France permanently with the fall of Calais in 1558 . In total , five Tudor monarchs ruled their domains for just over a century . Henry VIII was the only male-line male heir of Henry VII to live to the age of maturity . Issues around the royal succession ( including marriage and the succession rights of women ) became major political themes during the Tudor era . The House of Stuart , descended from Henry VIII 's sister Margaret , came to power in 1603 when the direct Tudor line failed , as Elizabeth I died without a legitimate heir .", "title": "" }, { "docid": "Wives_of_Henry_VIII", "text": "The wives of Henry VIII were the six queens consort wedded to Henry VIII of England between 1509 and 1547 . The six women who were married to Henry VIII were , in chronological order : Catherine of Aragon ( marriage annulled , died while detained under guard at Kimbolton Castle , mother of Mary I ) Anne Boleyn ( marriage annulled , then beheaded , mother of Elizabeth I ) Jane Seymour ( died twelve days after giving birth to Edward VI , believed to be caused by birth complications ) Anne of Cleves ( marriage annulled , outlived the rest of the wives ) Catherine Howard ( beheaded ) Catherine Parr ( widowed at death of Henry VIII , remarried to Thomas Seymour ) Henry 's first marriage lasted nearly 24 years , while the remaining five totaled less than 10 years combined . A common mnemonic device to remember the fates of Henry 's consorts is `` Divorced , beheaded , died , divorced , beheaded , survived '' . There is also a rhyme : However , Henry did not `` divorce '' two wives , but rather had the marriages annulled . At the time , the laws relating to marriage were under the jurisdiction of canon law , and there was no divorce under canon law . Henry 's marriage to Anne Boleyn was also annulled before her death . So if one accepts the courts ' finding that the annulled marriages had never existed , Henry only had three wives : Seymour , Howard and Parr . So the rhyme would be more like this : It is often noted that Catherine Parr `` survived him . '' In fact , Anne of Cleves also survived the king , and was the last of his queens to die . Of the six queens , Catherine of Aragon , Anne Boleyn , and Jane Seymour each gave Henry one child who survived infancy : two daughters and one son . All three of these children would eventually ascend to the throne : King Edward VI , Queen Mary I , and Queen Elizabeth I. Catherine Howard and Anne Boleyn , the two of Henry 's queens who were beheaded , were first cousins . Several of Henry 's wives worked in at least one of his other wives ' service , typically as ladies-in-waiting : Anne Boleyn worked in Catherine of Aragon 's service , Jane Seymour worked in Catherine of Aragon 's and Anne Boleyn 's , and Catherine Howard worked in Anne of Cleves 's .

Hostilities lasted from 3 to 6 months starting around Easter of 1088 . The Anarchy ( 1135 -- 54 ) -- in England , The Anarchy was a civil war in England and Normandy between 1135 and 1154 , which resulted in a widespread breakdown in law and order . The conflict began with a succession crisis towards the end of the reign of Henry I , when the king 's only legitimate son , William Adelin , died aboard the White Ship in 1120 . Henry 's attempts to install his daughter , the Empress Matilda , as his successor were unsuccessful and on Henry 's death in 1135 , his nephew Stephen of Blois seized the throne with the help of his brother , Henry , bishop of Winchester . Stephen 's early reign was marked by fierce fighting with English barons , rebellious Welsh leaders and Scottish invaders . Following a major rebellion in the south-west of England , Matilda invaded in 1139 with the help of her half-brother , Robert of Gloucester . First Barons ' War ( 1215 -- 17 ) -- in England , The First Barons ' War ( 1215 -- 17 ) was a civil war in the Kingdom of England in which a group of rebellious barons , led by Robert Fitzwalter and supported by a French army under the future Louis VIII of France , made war on King John of England . The war resulted from the king 's refusal to accept and abide by the Magna Carta he had sealed on 15 June 1215 , and from the ambitions of the French prince , who dragged the war on after many of the rebel barons had made peace with John . Second Barons ' War ( 1264 -- 67 ) -- in England , The Second Barons ' War ( 1264 -- 67 ) was a civil war in England between the forces of a number of barons led by Simon de Montfort against Royalist forces led by Prince Edward ( later Edward I of England ) , in the name of Henry III . Despenser War ( 1321 -- 22 ) -- Baronial revolt against Edward II instigated by Marcher Lords in opposition to court favourite Hugh Despenser . Wars of the Roses ( 1455 -- 87 ) -- in England and Wales ; Richard III was the last English king to die in combat , The Wars of the Roses were a series of dynastic wars for the throne of England . They were fought between supporters of two rival branches of the royal House of Plantagenet , the houses of Lancaster and York . They were fought in several sporadic episodes between 1455 and 1487 . The English Civil War ( 1642 -- 51 ) was a series of armed conflicts and political machinations between Parliamentarians ( `` Roundheads '' ) and Royalists ( `` Cavaliers '' ) in the Kingdom of England over , principally , the manner of its government . The first ( 1642 -- 46 ) and second ( 1648 -- 49 ) wars pitted the supporters of King Charles I against the supporters of the Long Parliament , while the third ( 1649 -- 51 ) saw fighting between supporters of King Charles II and supporters of the Rump Parliament . The war ended with the Parliamentarian victory at the Battle of Worcester on 3 September 1651 . The overall outcome of the war was threefold : the trial and execution of Charles I ; the exile of his son , Charles II ; and the replacement of English monarchy with , at first , the Commonwealth of England ( 1649 -- 53 ) and then the Protectorate ( 1653 -- 59 ) under Oliver Cromwell 's personal rule . The monopoly of the Church of England on Christian worship in England ended . Constitutionally , the wars established the precedent that an English monarch can not govern without Parliament 's consent , although the idea of parliament as the ruling power of England was legally established as part of the Glorious Revolution in 1688 .

The daughter of Isabella I of Castile and Ferdinand II of Aragon , Catherine was three years old when she was betrothed to Arthur , Prince of Wales , heir apparent to the English throne . They married in 1501 , but Arthur died five months later on 2 April 1502 . In 1507 , she held the position of ambassador of the Aragonese Crown in England , the first female ambassador in European history . Catherine subsequently married Arthur 's younger brother , the recently ascended Henry VIII , in 1509 . For six months in 1513 , she served as regent of England while Henry VIII was in France . During that time the English won the Battle of Flodden , an event in which Catherine played an important part with an emotional speech about English courage . By 1525 , Henry VIII was infatuated with Anne Boleyn and dissatisfied that his marriage to Catherine had produced no surviving sons , leaving their daughter , the future Mary I of England , as heir presumptive at a time when there was no established precedent for a woman on the throne . He sought to have their marriage annulled , setting in motion a chain of events that led to England 's schism with the Catholic Church . When Pope Clement VII refused to annul the marriage , Henry defied him by assuming supremacy over religious matters . In 1533 their marriage was consequently declared invalid and Henry married Anne on the judgement of clergy in England , without reference to the Pope . Catherine refused to accept Henry as Supreme Head of the Church in England and considered herself the King 's rightful wife and queen , attracting much popular sympathy . Despite this , she was acknowledged only as Dowager Princess of Wales by Henry . After being banished from court , she lived out the remainder of her life at Kimbolton Castle , and died there on 7 January 1536 . English people held Catherine in high esteem , and her death set off tremendous mourning . The controversial book The Education of a Christian Woman by Juan Luis Vives , which claimed women have the right to an education , was commissioned by and dedicated to her . Such was Catherine 's impression on people that even her enemy , Thomas Cromwell , said of her , `` If not for her sex , she could have defied all the heroes of History . '' She successfully appealed for the lives of the rebels involved in the Evil May Day , for the sake of their families . Catherine also won widespread admiration by starting an extensive programme for the relief of the poor .

HNF4A mutations are associated with macrosomia in infancy.

The increased rate of macrosomia in the offspring of pregnant women with diabetes and in congenital hyperinsulinaemia is mediated by increased foetal insulin secretion. We assessed the in utero and neonatal role of two key regulators of pancreatic insulin secretion by studying birthweight and the incidence of neonatal hypoglycaemia in patients with heterozygous mutations in the maturity-onset diabetes of the young (MODY) genes HNF4A (encoding HNF-4α) and HNF1A/TCF1 (encoding HNF-1α), and the effect of pancreatic deletion of Hnf4a on foetal and neonatal insulin secretion in mice.", "title": "Macrosomia and Hyperinsulinaemic Hypoglycaemia in Patients with Heterozygous Mutations in the HNF4A Gene" } ]
[ { "docid": "24269361", "text": "There are two main families of polyunsaturated fatty acids (PUFAs), the n-6 and the n-3 families. It has been suggested that there is a causal relationship between n-6 PUFA intake and allergic disease, and there are biologically plausible mechanisms, involving eicosanoid mediators of the n-6 PUFA arachidonic acid, that could explain this. Fish and fish oils are sources of long-chain n-3 PUFAs and these fatty acids act to oppose the actions of n-6 PUFAs. Thus, it is considered that n-3 PUFAs will protect against atopic sensitization and against the clinical manifestations of atopy. Evidence to examine this has been acquired from epidemiologic studies investigating associations between fish intake in pregnancy, lactation, infancy, and childhood, and atopic outcomes in infants and children and from intervention studies with fish oil supplements in pregnancy, lactation, infancy, and childhood, and atopic outcomes in infants and children. All five epidemiological studies investigating the effect of maternal fish intake during pregnancy on atopic or allergic outcomes in infants/children of those pregnancies concluded protective associations. One study investigating the effects of maternal fish intake during lactation did not observe any significant associations. The evidence from epidemiological studies investigating the effects of fish intake during infancy and childhood on atopic outcomes in those infants or children is inconsistent, although the majority of the studies (nine of 14) showed a protective effect of fish intake during infancy or childhood on atopic outcomes in those infants/children. Fish oil supplementation during pregnancy and lactation or during infancy or childhood results in a higher n-3 PUFA status in the infants or children. Fish oil provision to pregnant women is associated with immunologic changes in cord blood and such changes may persist. Studies performed to date indicate that provision of fish oil during pregnancy may reduce sensitization to common food allergens and reduce prevalence and severity of atopic dermatitis in the first year of life, with a possible persistence until adolescence with a reduction in eczema, hay fever, and asthma. Fish oil provision to infants or children may be associated with immunologic changes in the blood but it is not clear if these are of clinical significance and whether they persist. Fish oil supplementation in infancy may decrease the risk of developing some manifestations of allergic disease, but this benefit may not persist as other factors come into play. It is not clear whether fish oil can be used to treat children with asthma as the two studies conducted to date give divergent results. Further studies of increased long-chain n-3 PUFA provision in during pregnancy, lactation, and infancy are needed to more clearly identify the immunologic and clinical effects in infants and children and to identify protective and therapeutic effects and their persistence.", "title": "Atopy risk in infants and children in relation to early exposure to fish, oily fish, or long-chain omega-3 fatty acids: a systematic review." }, { "docid": "15678772", "text": "OBJECTIVE To determine whether exposure to low doses of ionising radiation in infancy affects cognitive function in adulthood.

On the basis of two consanguineous families, we mapped WRS to a region of less than 3 cM on chromosome 2p12, with maximal evidence of linkage and homozygosity at 4 microsatellite markers within an interval of approximately 1 cM. The gene encoding the eukaryotic translation initiation factor 2-α kinase 3 (EIF2AK3) resides in this interval; thus we explored it as a candidate. We identified distinct mutations of EIF2AK3 that segregated with the disorder in each of the families. The first mutation produces a truncated protein in which the entire catalytic domain is missing. The other changes an amino acid, located in the catalytic domain of the protein, that is highly conserved among kinases from the same subfamily.

We analysed data from five long-standing prospective cohort studies from Brazil, Guatemala, India, the Philippines, and South Africa and noted that indices of maternal and child undernutrition (maternal height, birthweight, intrauterine growth restriction, and weight, height, and body-mass index at 2 years according to the new WHO growth standards) were related to adult outcomes (height, schooling, income or assets, offspring birthweight, body-mass index, glucose concentrations, blood pressure). We undertook systematic reviews of studies from low-income and middle-income countries for these outcomes and for indicators related to blood lipids, cardiovascular disease, lung and immune function, cancers, osteoporosis, and mental illness. Undernutrition was strongly associated, both in the review of published work and in new analyses, with shorter adult height, less schooling, reduced economic productivity, and--for women--lower offspring birthweight. Associations with adult disease indicators were not so clear-cut. Increased size at birth and in childhood were positively associated with adult body-mass index and to a lesser extent with blood pressure values, but not with blood glucose concentrations. In our new analyses and in published work, lower birthweight and undernutrition in childhood were risk factors for high glucose concentrations, blood pressure, and harmful lipid profiles once adult body-mass index and height were adjusted for, suggesting that rapid postnatal weight gain--especially after infancy--is linked to these conditions. The review of published works indicates that there is insufficient information about long-term changes in immune function, blood lipids, or osteoporosis indicators. Birthweight is positively associated with lung function and with the incidence of some cancers, and undernutrition could be associated with mental illness. We noted that height-for-age at 2 years was the best predictor of human capital and that undernutrition is associated with lower human capital. We conclude that damage suffered in early life leads to permanent impairment, and might also affect future generations. Its prevention will probably bring about important health, educational, and economic benefits.

Until this process is completed, the cardiorespiratory system is unstable, placing infants at risk for cardiorespiratory disturbances, especially during sleep. The profound influence of states of alertness on respiratory and cardiac control has been the focus of intense scrutiny during the last decade. The effects of rapid-eye movement (REM) sleep on various mechanisms involved in cardiorespiratory control are of particular significance during the postnatal period since newborns spend much of their time in this sleep state. In fullterm newborns, REM sleep occupies more than 50% of total sleep time, and this percentage is even greater in preterm newborns. From term to six months of age, the proportion of REM sleep decreases. Since respiratory and cardiac disturbances are known to occur selectively during REM sleep, the predominance of REM sleep may be a risk factor for abnormal sleep-related events during early infancy. Awareness of these developmental changes in sleep patterns is important for clinicians dealing with problems such as apparent life-threatening events (ALTE), sudden infant death syndrome (SIDS), and/or cardiorespiratory responses to respiratory disorders. Our current understanding of respiratory and cardiac control rests mainly on studies conducted during the first months of life. There is a paucity of data on late infancy and early childhood. The present paper will review available data on how sleep affects 1) ventilatory mechanics, in particular of the upper airways and the chest wall; ventilation and apnea; gas exchange; chemoreceptor function; and arousal responses; 2) changes in heart rate and heart rate variability, and the occurrence and mechanisms of bradycardia.", "title": "Cardiorespiratory adaptation during sleep in infants and children." }, { "docid": "3446400", "text": "Transcriptional misregulation is involved in the development of many diseases, especially neoplastic transformation.

INTERVENTION Participants were randomly assigned to receive individualized counseling aimed at limiting the child's fat intake to 30% to 35% of daily energy, with a saturated:monounsaturated:polyunsaturated fatty acid ratio of 1:1:1 and a cholesterol intake of less than 200 mg/d (n = 540) or usual health education (control group, n = 522). MAIN OUTCOME MEASURES Nutrient intake, serum lipid concentrations, and neurological development at 5 years, among children in the intervention vs control groups. RESULTS Absolute and relative intakes of fat, saturated fatty acids, and cholesterol among children in the intervention group were markedly less than the respective values of control children. Mean (SD) percentages of daily energy at age 5 years for the intervention vs control groups were as follows: for total fat, 30.6% (4.5%) vs 33.4% (4.4%) (P<. 001); and for saturated fat, 11.7% (2.3%) vs 14.5% (2.4%) (P<.001). Mean intakes of cholesterol were 164.2 mg (60.1 mg) and 192.5 mg (71. 9 mg) (P<.001) for the intervention and control groups, respectively. Serum cholesterol concentrations were continuously 3% to 5% lower in children in the intervention group than in children in the control group. At age 5 years, mean (SD) serum cholesterol concentration of the intervention group was 4.27 (0.63) mmol/L (165 [24] mg/dL) and of the control group, 4.41 (0.74) mmol/L (170 [29] mg/dL) (P =.04). Neurological development of children in the intervention group was at least as good as that of children in the control group. Relative risks for children in the intervention group to fail tests of speech and language skills, gross motor functioning plus perception, and visual motor skills were 0.95 (90% confidence interval [CI], 0.60-1.49), 0.95 (90% CI, 0.58-1.55), and 0.65 (90% CI, 0.39-1.08), respectively (P =.85,.86, and.16, respectively, vs control children). CONCLUSION Our data indicate that repeated child-targeted dietary counseling of parents during the first 5 years of a child's life lessens age-associated increases in children's serum cholesterol and is compatible with normal neurological development.

Almost all known RT inhibitor resistance mutations identified to date map to the polymerase domain of the enzyme. However, the connection and RNase H domains are not routinely analysed in clinical samples and none of the genotyping assays available for patient management sequence the entire RT coding region. The British Columbia Centre for Excellence in HIV/AIDS (the Centre) genotypes clinical isolates up to codon 400 in RT, and our retrospective statistical analyses of the Centre’s database have identified an N348I mutation in the RT connection domain in treatment-experienced individuals. The objective of this multidisciplinary study was to establish the in vivo relevance of this mutation and its role in drug resistance. Methods and Findings The prevalence of N348I in clinical isolates, the time taken for it to emerge under selective drug pressure, and its association with changes in viral load, specific drug treatment, and known drug resistance mutations was analysed from genotypes, viral loads, and treatment histories from the Centre’s database. N348I increased in prevalence from below 1% in 368 treatmentnao ¨ve individuals to 12.1% in 1,009 treatment-experienced patients (p ¼ 7.7 3 10 � 12 ). N348I appeared early in therapy and was highly associated with thymidine analogue mutations (TAMs) M41L and T215Y/F (p , 0.001), the lamivudine resistance mutations M184V/I (p , 0.001), and non-nucleoside RTI (NNRTI) resistance mutations K103N and Y181C/I (p , 0.001). The association with TAMs and NNRTI resistance mutations was consistent with the selection of N348I in patients treated with regimens that included both zidovudine and nevirapine (odds ratio 2.62, 95% confidence interval 1.43–4.81). The appearance of N348I was associated with a significant increase in viral load (p , 0.001), which was as large as the viral load increases observed for any of the TAMs. However, this analysis did not account for the simultaneous selection of other RT or protease inhibitor resistance mutations on viral load. To delineate the role of this mutation in RT inhibitor resistance, N348I was introduced into HIV-1 molecular clones containing different genetic backbones. N348I decreased zidovudine susceptibility 2- to 4-fold in the context of wildtype HIV-1 or when combined with TAMs. N348I also decreased susceptibility to nevirapine (7.4fold) and efavirenz (2.5-fold) and significantly potentiated resistance to these drugs when combined with K103N. Biochemical analyses of recombinant RT containing N348I provide supporting evidence for the role of this mutation in zidovudine and NNRTI resistance and give some insight into the molecular mechanism of resistance.

OBJECTIVE To identify mutation-specific cancer risks for carriers of BRCA1/2. DESIGN, SETTING, AND PARTICIPANTS Observational study of women who were ascertained between 1937 and 2011 (median, 1999) and found to carry disease-associated BRCA1 or BRCA2 mutations. The international sample comprised 19,581 carriers of BRCA1 mutations and 11,900 carriers of BRCA2 mutations from 55 centers in 33 countries on 6 continents. We estimated hazard ratios for breast and ovarian cancer based on mutation type, function, and nucleotide position. We also estimated RHR, the ratio of breast vs ovarian cancer hazard ratios. A value of RHR greater than 1 indicated elevated breast cancer risk; a value of RHR less than 1 indicated elevated ovarian cancer risk. EXPOSURES Mutations of BRCA1 or BRCA2. MAIN OUTCOMES AND MEASURES Breast and ovarian cancer risks. RESULTS Among BRCA1 mutation carriers, 9052 women (46%) were diagnosed with breast cancer, 2317 (12%) with ovarian cancer, 1041 (5%) with breast and ovarian cancer, and 7171 (37%) without cancer. Among BRCA2 mutation carriers, 6180 women (52%) were diagnosed with breast cancer, 682 (6%) with ovarian cancer, 272 (2%) with breast and ovarian cancer, and 4766 (40%) without cancer.

However, DNA copy number and gene expression signatures indicate differences between adult and paediatric cases. To explore the genetic events underlying this distinction, we sequenced the exomes of 48 paediatric GBM samples. Somatic mutations in the H3.3-ATRX-DAXX chromatin remodelling pathway were identified in 44% of tumours (21/48). Recurrent mutations in H3F3A, which encodes the replication-independent histone 3 variant H3.3, were observed in 31% of tumours, and led to amino acid substitutions at two critical positions within the histone tail (K27M, G34R/G34V) involved in key regulatory post-translational modifications. Mutations in ATRX (α-thalassaemia/mental retardation syndrome X-linked) and DAXX (death-domain associated protein), encoding two subunits of a chromatin remodelling complex required for H3.3 incorporation at pericentric heterochromatin and telomeres, were identified in 31% of samples overall, and in 100% of tumours harbouring a G34R or G34V H3.3 mutation. Somatic TP53 mutations were identified in 54% of all cases, and in 86% of samples with H3F3A and/or ATRX mutations. Screening of a large cohort of gliomas of various grades and histologies (n = 784) showed H3F3A mutations to be specific to GBM and highly prevalent in children and young adults. Furthermore, the presence of H3F3A/ATRX-DAXX/TP53 mutations was strongly associated with alternative lengthening of telomeres and specific gene expression profiles.

Chronic postnatal hypoxia present during infancy in these children may play a role in these impairments. To understand the biochemical mechanisms of hippocampal injury in chronic hypoxia, a neurochemical profile consisting of 15 metabolite concentrations and 2 metabolite ratios in the hippocampus was evaluated in a rat model of chronic postnatal hypoxia using in vivo 1H NMR spectroscopy at 9.4 T. Chronic hypoxia was induced by continuously exposing rats (n = 23) to 10% O2 from postnatal day (P) 3 to P28. Fifteen metabolites were quantified from a volume of 9-11 microl centered on the left hippocampus on P14, P21, and P28 and were compared with normoxic controls (n = 14). The developmental trajectory of neurochemicals in chronic hypoxia was similar to that seen in normoxia. However, chronic hypoxia had an effect on the concentrations of the following neurochemicals: aspartate, creatine, phosphocreatine, GABA, glutamate, glutamine, glutathione, myoinositol, N-acetylaspartate (NAA), phosphorylethanolamine, and phosphocreatine/creatine (PCr/Cr) and glutamate/glutamine (Glu/Gln) ratios (P < 0.001 each, except glutamate, P = 0.04). The increased PCr/Cr ratio is consistent with decreased brain energy consumption. Given the well-established link between excitatory neurotransmission and brain energy metabolism, we postulate that elevated glutamate, Glu/Gln ratio, and GABA indicate suppressed excitatory neurotransmission in an energy-limited environment. Decreased NAA and phosphorylethanolamine suggest reduced neuronal integrity and phospholipid metabolism.

Recent work suggested a possible correlation between pathological features such as frequency of basophilic inclusions in neurons and rate of clinical decline, other studies have revealed a discrepancy between the upper motor neuron features detected clinically and the associated pathology. The purpose of this study was to describe the pathological features associated with more recently discovered FUS mutations and reinvestigate those with well recognised mutations in an attempt to correlate the pathology with mutation and/or clinical phenotype. The brains and spinal cords of seven cases of ALS-FUS were examined neuropathologically, including cases with the newly described p. K510E mutation and a case with both a known p. P525L mutation in the FUS gene and a truncating p. Y374X mutation in the TARDBP gene. RESULTS The neuropathology in all cases revealed basophilic and FUS inclusions in the cord. The density and type of inclusions varied markedly between cases, but did not allow a clear correlation with clinical progression. Only one case showed significant motor cortical pathology despite the upper motor neuron clinical features being evident in 4 patients. The case with both a FUS and TARDBP mutation revealed FUS positive inclusions but no TDP-43 pathology. Instead there were unusual p62 positive, FUS negative neuronal and glial inclusions as well as dot-like neurites. CONCLUSIONS The study confirms cases of ALS-FUS to be mainly a lower motor neuron disease and to have pathology that does not appear to neatly correlate with clinical features or genetics. Furthermore, the case with both a FUS and TARDBP mutation reveals an intriguing pathological profile which at least in part involves a very unusual staining pattern for the ubiquitin-binding protein p62.", "title": "ALS-FUS pathology revisited: singleton FUS mutations and an unusual case with both a FUS and TARDBP mutation" }, { "docid": "4414547", "text": "Improved sequencing technologies offer unprecedented opportunities for investigating the role of rare genetic variation in common disease. However, there are considerable challenges with respect to study design, data analysis and replication. Using pooled next-generation sequencing of 507 genes implicated in the repair of DNA in 1,150 samples, an analytical strategy focused on protein-truncating variants (PTVs) and a large-scale sequencing case–control replication experiment in 13,642 individuals, here we show that rare PTVs in the p53-inducible protein phosphatase PPM1D are associated with predisposition to breast cancer and ovarian cancer. PPM1D PTV mutations were present in 25 out of 7,781 cases versus 1 out of 5,861 controls (P = 1.12 × 10−5), including 18 mutations in 6,912 individuals with breast cancer (P = 2.42 × 10−4) and 12 mutations in 1,121 individuals with ovarian cancer (P = 3.10 × 10−9). Notably, all of the identified PPM1D PTVs were mosaic in lymphocyte DNA and clustered within a 370-base-pair region in the final exon of the gene, carboxy-terminal to the phosphatase catalytic domain. Functional studies demonstrate that the mutations result in enhanced suppression of p53 in response to ionizing radiation exposure, suggesting that the mutant alleles encode hyperactive PPM1D isoforms. Thus, although the mutations cause premature protein truncation, they do not result in the simple loss-of-function effect typically associated with this class of variant, but instead probably have a gain-of-function effect.

Calcium intake during adolescence appears to affect skeletal calcium retention directly, and a calcium intake of up to 1600 mg d-1 may be required. Therefore, adolescent females at the time of puberty probably represent the optimal population for early prevention of osteoporosis with calcium. Young individuals must be in positive calcium balance to provide the calcium necessary for skeletal modelling and consolidation, but the degree of positive balance required to achieve peak bone mass and density is unknown. To assess calcium requirements in young individuals, and also to evaluate the determinants of calcium metabolism during the period of acquisition of peak bone mass, 487 calcium balances from previously published reports have been collected and analysed according to developmental phase and calcium intake. The results of this analysis showed that calcium intake and skeletal modelling/turnover are the most important determinants of calcium balance during growth. The highest requirements for calcium are during infancy and adolescence, and then during childhood and young adulthood. Infants (adequate vitamin D supply) and adolescents have higher calcium absorption than children and young adults to meet their high calcium requirements. Calcium absorption during the periods of rapid bone modelling/turnover is probably mediated by Nicolaysen's endogenous factor. Urinary calcium increases with age, and reaches a maximum by the end of puberty. The results also show that calcium intake has little effect on urinary calcium excretion during the period of most rapid skeletal formation: a weak correlation is present in children and young adults. On the basis of the above studies it was suggested that the RDA for calcium should be higher than currently established for children, adolescents, and young adults, in order to ensure a level of skeletal retention of calcium sufficient for maximal peak bone mass. In addition to nutrition, heredity (both parents) and endocrine factors (sexual development) appear to have profound effects on peak bone mass formation.

We characterized the consequences of intratumor heterogeneity using immunohistochemical analysis, mutation functional analysis, and profiling of messenger RNA expression. RESULTS Phylogenetic reconstruction revealed branched evolutionary tumor growth, with 63 to 69% of all somatic mutations not detectable across every tumor region. Intratumor heterogeneity was observed for a mutation within an autoinhibitory domain of the mammalian target of rapamycin (mTOR) kinase, correlating with S6 and 4EBP phosphorylation in vivo and constitutive activation of mTOR kinase activity in vitro. Mutational intratumor heterogeneity was seen for multiple tumor-suppressor genes converging on loss of function; SETD2, PTEN, and KDM5C underwent multiple distinct and spatially separated inactivating mutations within a single tumor, suggesting convergent phenotypic evolution.

The octanoyl modification at Ser³, mediated by ghrelin O-acyltransferase (GOAT), is essential for ghrelin's biological activity. Ghrelin stimulates food intake through binding to its receptor (GRLN-R) on neurons in the arcuate nucleus of the hypothalamus. Ghrelin is widely expressed throughout the body; accordingly, it is implicated in several other physiological functions, which include growth hormone release, gastric emptying, and body weight regulation. Ghrelin and GRLN-R expression are also found in the pancreas, suggesting a local physiological role. Accordingly, several recent studies now point towards an important role for ghrelin and its receptor in the regulation of blood glucose homeostasis, which is the main focus of this review. Several mechanisms of this regulation by ghrelin have been proposed, and one possibility is through the regulation of insulin secretion. Despite some controversy, most studies suggest that ghrelin exerts an inhibitory effect on insulin secretion, resulting in increased circulating glucose levels. Ghrelin may thus be a diabetogenic factor. Obesity-related type 2 diabetes has become an increasingly important health problem, almost reaching epidemic proportions in the world; therefore, antagonists of the ghrelin-GOAT signaling pathway, which will tackle both energy- and glucose homeostasis, may be considered as promising new therapies for this disease.", "title": "Ghrelin's second life: from appetite stimulator to glucose regulator." }, { "docid": "2481032", "text": "Sirt1 is a NAD(+)-dependent class III deacetylase that functions as a cellular energy sensor. In addition to its well-characterized effects in peripheral tissues, emerging evidence suggests that neuronal Sirt1 activity plays a role in the central regulation of energy balance and glucose metabolism. To assess this idea, we generated Sirt1 neuron-specific knockout (SINKO) mice. On both standard chow and HFD, SINKO mice were more insulin sensitive than Sirt1(f/f) mice. Thus, SINKO mice had lower fasting insulin levels, improved glucose tolerance and insulin tolerance, and enhanced systemic insulin sensitivity during hyperinsulinemic euglycemic clamp studies. Hypothalamic insulin sensitivity of SINKO mice was also increased over controls, as assessed by hypothalamic activation of PI3K, phosphorylation of Akt and FoxO1 following systemic insulin injection. Intracerebroventricular injection of insulin led to a greater systemic effect to improve glucose tolerance and insulin sensitivity in SINKO mice compared with controls. In line with the in vivo results, insulin-induced AKT and FoxO1 phosphorylation were potentiated by inhibition of Sirt1 in a cultured hypothalamic cell line. Mechanistically, this effect was traced to a reduced effect of Sirt1 to directly deacetylate and repress IRS-1 function. The enhanced central insulin signaling in SINKO mice was accompanied by increased insulin receptor signal transduction in liver, muscle, and adipose tissue.

METHODOLOGY AND PRINCIPAL FINDINGS HUMSCs were induced to transform into islet-like cell clusters in vitro through stepwise culturing in neuron-conditioned medium. To assess the functional stability of the islet-like cell clusters in vivo, these cell clusters were transplanted into the liver of streptozotocin-induced diabetic rats via laparotomy. Glucose tolerance was measured on week 12 after transplantation accompanied with immunohistochemistry and electron microscopy analysis. These islet-like cell clusters were shown to contain human C-peptide and release human insulin in response to physiological glucose levels. Real-time RT-PCR detected the expressions of insulin and other pancreatic beta-cell-related genes (Pdx1, Hlxb9, Nkx2.2, Nkx6.1, and Glut-2) in these islet-like cell clusters.

The results demonstrated a ventral temporo-frontal stream of fibers that originate from various auditory, multisensory, and visual association cortical areas in the intermediate superolateral temporal region. These axons course via the extreme capsule and target most strongly area 45 with a more modest termination in area 44.

METHODS AND RESULTS The roles of FGF21 in atherosclerosis were investigated by evaluating the impact of FGF21 deficiency and replenishment with recombinant FGF21 in apolipoprotein E(-/-) mice. FGF21 deficiency causes a marked exacerbation of atherosclerotic plaque formation and premature death in apolipoprotein E(-/-) mice, which is accompanied by hypoadiponectinemia and severe hypercholesterolemia. Replenishment of FGF21 protects against atherosclerosis in apolipoprotein E(-/-)mice via 2 independent mechanisms, inducing the adipocyte production of adiponectin, which in turn acts on the blood vessels to inhibit neointima formation and macrophage inflammation, and suppressing the hepatic expression of the transcription factor sterol regulatory element-binding protein-2, thereby leading to reduced cholesterol synthesis and attenuation of hypercholesterolemia. Chronic treatment with adiponectin partially reverses atherosclerosis without obvious effects on hypercholesterolemia in FGF21-deficient apolipoprotein E(-/-) mice. By contrast, the cholesterol-lowering effects of FGF21 are abrogated by hepatic expression of sterol regulatory element-binding protein-2.

We now demonstrate that neurons regulate glial glutamate turnover via pituitary adenylate cyclase-activating polypeptide (PACAP). In the cerebral cortex PACAP is synthesized by neurons and acts on the subpopulation of astroglia involved in glutamate turnover. Exposure of astroglia to PACAP increased the maximal velocity of [(3)H]glutamate uptake by promoting the expression of GLT-1, GLAST, and GS. Moreover, the stimulatory effects of neuron-conditioned medium on glial glutamate transporter expression were attenuated in the presence of PACAP-inactivating antibodies or the PACAP receptor antagonist PACAP 6-38.

Anterior LHA glutamatergic neurons send a functional glutamatergic projection to the LHb, a brain region involved in processing aversive stimuli and negative reward prediction outcomes. Pathway-specific, optogenetic stimulation of glutamatergic LHA-LHb circuit resulted in detectable glutamate-mediated EPSCs as well as GABA-mediated IPSCs, although the net effect of neurotransmitter release was to increase the firing of most LHb neurons. In vivo optogenetic inhibition of LHA-LHb glutamatergic fibers produced a real-time place preference, whereas optogenetic stimulation of LHA-LHb glutamatergic fibers had the opposite effect.

The DV patterning is so robust that an amphibian embryo with its ventral half surgically removed can develop into a smaller but proportionally patterned larva. Here, we show that this robust patterning depends on facilitated Chordin degradation and requires the expression of the Chordin-proteinase inhibitor Sizzled on the opposite side. Sizzled, which is stable and diffuses widely along the DV axis, stabilizes Chordin and expands its distribution in the ventral direction. This expanded Chordin distribution, in turn, limits BMP-dependent Sizzled production, forming an axis-wide feedback loop for shaping Chordin's activity. Using bisection assays, we demonstrate that Chordin degradation is dynamically controlled by embryo-size-coupled Sizzled accumulation.

One possible explanation is that successful treatment strategy may require simultaneous targeting of more than one molecule of pathway. A new therapeutic approach to have emerged recently is the engagement of microRNAs (miRNAs), which affords the opportunity to target multiple cellular pathways simultaneously using a single sequence. METHODOLOGY/PRINCIPAL FINDINGS We identified miR-22 as a potentially neuroprotective miRNA based on its predicted regulation of several targets implicated in Huntington's disease (histone deacetylase 4 (HDAC4), REST corepresor 1 (Rcor1) and regulator of G-protein signaling 2 (Rgs2)) and its diminished expression in Huntington's and Alzheimer's disease brains. We then tested the hypothesis that increasing cellular levels of miRNA-22 would achieve neuroprotection in in vitro models of neurodegeneration. As predicted, overexpression of miR-22 inhibited neurodegeneration in primary striatal and cortical cultures exposed to a mutated human huntingtin fragment (Htt171-82Q). Overexpression of miR-22 also decreased neurodegeneration in primary neuronal cultures exposed to 3-nitropropionic acid (3-NP), a mitochondrial complex II/III inhibitor. In addition, miR-22 improved neuronal viability in an in vitro model of brain aging. The mechanisms underlying the effects of miR-22 included a reduction in caspase activation, consistent with miR-22's targeting the pro-apoptotic activities of mitogen-activated protein kinase 14/p38 (MAPK14/p38) and tumor protein p53-inducible nuclear protein 1 (Tp53inp1). Moreover, HD-specific effects comprised not only targeting HDAC4, Rcor1 and Rgs2 mRNAs, but also decreasing focal accumulation of mutant Htt-positive foci, which occurred via an unknown mechanism. CONCLUSIONS These data show that miR-22 has multipartite anti-neurodegenerative activities including the inhibition of apoptosis and the targeting of mRNAs implicated in the etiology of HD.

These effects are mediated via activation of the Src/PI3K/AKT/mTOR signaling pathway, ultimately leading to a global increase in protein translation. Induction of neurogenesis by CD95 was further confirmed in the ischemic CA1 region, in the naive dentate gyrus, and after forced expression of CD95L in the adult subventricular zone.

We showed that NRG1 increased both the number and size of PSD-95 puncta and the frequency and amplitude of miniature EPSCs (mEPSCs) in GABAergic interneurons, indicating that NRG1 stimulates the formation of new synapses and strengthens existing synapses. In contrast, NRG1 treatment had no effect on either the number or size of excitatory synapses in glutamatergic neurons, suggesting its synaptogenic effect is specific to GABAergic interneurons. Ecto-ErbB4 treatment diminished both the number and size of excitatory synapses, suggesting that endogenous NRG1 may be critical for basal synapse formation. NRG1 could stimulate the stability of PSD-95 in the manner that requires tyrosine kinase activity of ErbB4. Finally, deletion of ErbB4 in parvalbumin-positive interneurons led to reduced frequency and amplitude of mEPSCs, providing in vivo evidence that ErbB4 is important in excitatory synaptogenesis in interneurons.

The need for multiple doses produces problems with medication administration during school and after-school hours, and therefore with compliance. Previous long-acting stimulants and preparations have shown effects equivalent to twice-daily dosing of MPH. This study tests the efficacy and duration of action, in natural and laboratory settings, of an extended-release MPH preparation designed to last 12 hours and therefore be equivalent to 3-times-daily dosing. METHODS Sixty-eight children with ADHD, 6 to 12 years old, participated in a within-subject, double-blind comparison of placebo, immediate-release (IR) MPH 3 times a day (tid), and Concerta, a once-daily MPH formulation. Three dosing levels of medication were used: 5 mg IR MPH tid/18 mg Concerta once a day (qd); 10 mg IR MPH tid/36 mg Concerta qd; and 15 mg IR MPH tid/54 mg Concerta qd. All children were currently medicated with MPH at enrollment, and each child's dose level was based on that child's MPH dosing before the study. The doses of Concerta were selected to be comparable to the daily doses of MPH that each child received. To achieve the ascending rate of MPH delivery determined by initial investigations to provide the necessary continuous coverage, Concerta doses were 20% higher on a daily basis than a comparable tid regimen of IR MPH. Children received each medication condition for 7 days. The investigation was conducted in the context of a background clinical behavioral intervention in both the natural environment and the laboratory setting. Parents received behavioral parent training and teachers were taught to establish a school-home daily report card (DRC). A DRC is a list of individual target behaviors that represent a child's most salient areas of impairment. Teachers set daily goals for each child's impairment targets, and parents provided rewards at home for goal attainment. Each weekday, teachers completed the DRC, and it was used as a dependent measure of individualized medication response. Teachers and parents also completed weekly standardized ratings of behavior and treatment effectiveness. To evaluate the time course of medication effects, children spent 12 hours in a laboratory setting on Saturdays and medication effects were measured using procedures and methods adapted from our summer treatment program. Measures of classroom behavior and academic productivity/accuracy were taken in a laboratory classroom setting during which children completed independent math and reading worksheets. Measures of social behavior were taken in structured, small-group board game settings and unstructured recess settings. Measures included behavior frequency counts, academic problems completed and accuracy, independent observations, teacher and counselor ratings, and individualized behavioral target goals. Reports of adverse events, sleep quality, and appetite were collected. RESULTS On virtually all measures in all settings, both drug conditions were significantly different from placebo, and the 2 drugs were not different from each other. In children's regular school settings, both medications improved behavior as measured by teacher ratings and individualized target behaviors (the DRC); these effects were seen into the evening as measured by parent ratings. In the laboratory setting, effects of Concerta were equivalent to tid MPH and lasted at least through 12 hours after dosing. Concerta was significantly superior to tid MPH on 2 parent rating scores, and when asked, more parents preferred Concerta than preferred tid IR MPH or placebo. Side effects on children's sleep and appetite were similar for the 2 preparations. In the lab setting, both medications improved productivity and accuracy on arithmetic seatwork assignments, disruptive and on-task behavior, and classroom rule following. Both medications improved children's rule following and negative behavior in small group board games, as well as in unstructured recess settings. Individual target behaviors also showed significant improvement with medication across domains in the laboratory setting. Children's behavior across settings deteriorated across the laboratory day, and the primary effect of medication was to prevent this deterioration as the day wore on. Results support the use of background behavioral treatment in clinical trials of stimulant medication, and illustrate the utility of a measure of individualized daily target goals (ie, the DRC) as an objective measure of medication response in both the laboratory and natural school settings. CONCLUSION This investigation clearly supports the efficacy of the Concerta long-acting formulation of MPH for parents who desire to have medication benefits for their child throughout the day and early evening.

In the aging nematode nervous system, neuronal death and/or detectable loss of processes are not readily apparent, but because dendrite restructuring and loss of synaptic integrity are hypothesized to contribute to human brain decline and dysfunction, we combined fluorescence microscopy and electron microscopy (EM) to screen at high resolution for nervous system changes. We report two major components of morphological change in the aging C. elegans nervous system: (1) accumulation of novel outgrowths from specific neurons, and (2) physical decline in synaptic integrity. Novel outgrowth phenotypes, including branching from the main dendrite or new growth from somata, appear at a high frequency in some aging neurons, but not all. Mitochondria are often associated with age-associated branch sites. Lowered insulin signaling confers some maintenance of ALM and PLM neuron structural integrity into old age, and both DAF-16/FOXO and heat shock factor transcription factor HSF-1 exert neuroprotective functions. hsf-1 can act cell autonomously in this capacity.

[ { "docid": "569565", "text": "\"I thought the other answers had some good aspect but also some things that might not be completely correct, so I'll take a shot. As noted by others, there are three different types of entities in your question: The ETF SPY, the index SPX, and options contracts. First, let's deal with the options contracts. You can buy options on the ETF SPY or marked to the index SPX. Either way, options are about the price of the ETF / index at some future date, so the local min and max of the \"\"underlying\"\" symbol generally will not coincide with the min and max of the options. Of course, the closer the expiration date on the option, the more closely the option price tracks its underlying directly. Beyond the difference in how they are priced, the options market has different liquidity, and so it may not be able to track quick moves in the underlying. (Although there's a reasonably robust market for option on SPY and SPX specifically.) Second, let's ask what forces really make SPY and SPX move together as much as they do. It's one thing to say \"\"SPY is tied to SPX,\"\" but how? There are several answers to this, but I'll argue that the most important factor is that there's a notion of \"\"authorized participants\"\" who are players in the market who can \"\"create\"\" shares of SPY at will. They do this by accumulating stock in the constituent companies and turning them into the market maker. There's also the corresponding notion of \"\"redemption\"\" by which an authorized participant will turn in a share of SPY to get stock in the constituent companies. (See http://www.spdrsmobile.com/content/how-etfs-are-created-and-redeemed and http://www.etf.com/etf-education-center/7540-what-is-the-etf-creationredemption-mechanism.html) Meanwhile, SPX is just computed from the prices of the constituent companies, so it's got no market forces directly on it. It just reflects what the prices of the companies in the index are doing. (Of course those companies are subject to market forces.) Key point: Creation / redemption is the real driver for keeping the price aligned. If it gets too far out of line, then it creates an arbitrage opportunity for an authorized participant. If the price of SPY gets \"\"too high\"\" compared to SPX (and therefore the constituent stocks), an authorized participant can simultaneously sell short SPY shares and buy the constituent companies' stocks. They can then use the redemption process to close their position at no risk. And vice versa if SPY gets \"\"too low.\"\" Now that we understand why they move together, why don't they move together perfectly. To some extent information about fees, slight differences in composition between SPY and SPX over time, etc. do play. The bigger reasons are probably that (a) there are not a lot of authorized participants, (b) there are a relatively large number of companies represented in SPY, so there's some actual cost and risk involved in trying to quickly buy/sell the full set to capture the theoretical arbitrage that I described, and (c) redemption / creation units only come in pretty big blocks, which complicates the issues under point b. You asked about dividends, so let me comment briefly on that too. The dividend on SPY is (more or less) passing on the dividends from the constituent companies. (I think - not completely sure - that the market maker deducts its fees from this cash, so it's not a direct pass through.) But each company pays on its own schedule and SPY does not make a payment every time, so it's holding a corresponding amount of cash between its dividend payments. This is factored into the price through the creation / redemption process. I don't know how big of a factor it is though.\"", "title": "" }, { "docid": "311214", "text": "To follow up on Quid's comment, the share classes themselves will define what level of dividends are expected. Note that the terms 'common shares' and 'preferred shares' are generally understood terms, but are not as precise as you might believe. There are dozens/hundreds of different characteristics that could be written into share classes in the company's articles of incorporation [as long as those characteristics are legal in corporate law in the company's jurisdiction]. So in answering your question there's a bit of an assumption that things are working 'as usual'. Note that private companies often have odd quirks to their share classes, things like weird small classes of shares that have most of the voting rights, or shares with 'shotgun buyback clauses'. As long as they are legal clauses, they can be used to help control how the business is run between various shareholders with competing interests. Things like parents anticipating future family infighting and trying to prevent familial struggle. You are unlikely to see such weird quirks in public companies, where the company will have additional regulatory requirements and where the public won't want any shock at unexpected share clauses. In your case, you suggested having a non-cumulative preferred share [with no voting rights, but that doesn't impact dividend payment]: There are two salient points left related to payout that the articles of incorporation will need to define for the share classes: (1) What is the redemption value for the shares? [This is usually equal to the cost of subscribing for the shares in the first place; it represents how much the business will need to pay the shareholder in the event of redemption / recall] (2) What is the stated dividend amount? This is usually defined at a rate that's at or a little above a reasonable interest rate at the time the shares are created, but defined as $ / share. For example, the shares could have $1 / share dividend payment, where the shares originally cost $50 each to subscribe [this would reflect a rate of payment of about 2%]. Typically by corporate law, dividends must be paid to preferred shares, to the extent required based on the characteristics of the share class [some preferred shares may not have any required dividends at all], before any dividends can be paid to common shares. So if $10k in dividends is to be paid, and total preferred shares require $15k of non-cumulative dividends each year, then $0 will be paid to the common shares. The following year, $15k of dividends will once again need to be paid to the preferred shares, before any can be paid to the common shares.", "title": "" }, { "docid": "61103", "text": "I'm guessing you're conflating bonus share issuance with stock split.

Sometimes a bonus share issuance is (incorrectly) called a stock split, like in this public announcement from STADA in 2004. It is a 1:1 bonus share issuance (meaning they issue one bonus share to everyone who has one share now), but it is in essence the same thing as a stock split (a 2:1 stock split, namely).

However, for the company to distribute stocks instead of cash may be advantageous if they have low cash reserves but significant amount of treasury stocks, and the stocks are of high liquidity. It is also a way for the company to release treasury stocks without diluting the current shareholders and creating taxable income to the company, that's an important factor to consider. This is in fact the real answer to your question. The main difference between split and stock dividend is that in split, the stock distributions proportions don't change. With stock dividend - they do. While the outstanding share proportions do not change, total proportions do, because of the treasury stocks being distributed. So company has less stocks in its vaults, but everyone else still has the same proportions of ownership.

Another reason is merely to enable the corporation to take advantage of the accepted accounting practice of capitalizing retained earnings.

Unless a company decides to issue more shares, the supply of shares of an individual stock trading in the marketplace is finite. When demand increases for shares of an ETF, however, Authorized Participants (APs) have the ability to create additional shares on demand. Through an \"\"in kind\"\" transfer mechanism, APs create ETF units in the primary market by delivering a basket of securities to the fund equal to the current holdings of the ETF. In return, they receive a large block of ETF shares (typically 50,000), which are then available for trading in the secondary market. This ETF creation and redemption process helps keep ETF supply and demand in continual balance and provides a \"\"hidden\"\" layer of liquidity not evident by looking at trading volumes alone. This process also works in reverse. If an investor wants to sell a large block of shares of an ETF, even if there seems to be limited liquidity in the secondary market, APs can readily redeem a block of ETF shares by gathering enough shares of the ETF to form a creation unit and then exchanging the creation unit for the underlying securities. Thus, the in-kind swap to the underlying securities is only done by APs so the outflow would be these individuals taking a large block of the ETF and swapping it for the underlying securities. The APs would be taking advantage of the difference between what the ETF's trading value and the value of the underlying securities.\"", "title": "" }, { "docid": "479461", "text": "\"The S&P 500 is an index. This refers to a specific collection of securities which is held in perfect proportion. The dollar value of an index is scaled arbitrarily and is based off of an arbitrary starting price. (Side note: this is why an index never has a \"\"split\"\"). Lets look at what assumptions are included in the pricing of an index: All securities are held in perfect proportion. This means that if you invest $100 in the index you will receive 0.2746 shares of IBM, 0.000478 shares of General Motors, etc. Also, if a security is added/dropped from the list, you are immediately rebalancing the remaining money. Zero commissions are charged. When the index is calculated, they are using the current price (last trade) of the underlying securities, they are not actually purchasing them. Therefore it assumes that securities may be purchased without commission or other liquidity costs. Also closely related is the following. The current price has full liquidity. If the last quoted price is $20 for a security, the index assumes that you can purchase an arbitrary amount of the security at that price with a counterparty that is willing to trade. Dividends are distributed immediately. If you own 500 equities, and most distributed dividends quarterly, this means you will receive on average 4 dividends per day. Management is free. All equities can be purchased with zero research and administrative costs. There is no gains tax. Trading required by the assumptions above would change your holdings constantly and you are exempt from short-term or long-term capital gains taxes. Each one of these assumptions is, of course, invalid. And the fund which endeavors to track the index must make several decisions in how to closely track the index while avoiding the problems (costs) caused by the assumptions. These are shortcuts or \"\"approximations\"\". Each shortcut leads to performance which does not exactly match the index. Management fees. Fees are charged to the investor as load, annual fees and/or redemptions. Securities are purchased at real prices. If Facebook were removed from the S&P 500 overnight tonight, the fund would sell its shares at the price buyers are bidding the next market day at 09:30. This could be significantly different than the price today, which the index records. Securities are purchased in blocks. Rather than buying 0.000478 shares of General Motors each time someone invests a dollar, they wait for a few people and then buy a full share or a round lot. Securities are substituted. With lots of analysis, it may be determined that two stocks move in tandem. The fund may purchase two shares of General Motors rather than one of General Motors and Ford. This halves transaction costs. Debt is used. As part of substitution, equities may be replaced by options. Option pricing shows that ownership of options is equivalent to holding an amount of debt.

The stock is usually a capital asset for investors, who will generate capital gains under §1(h), but dealers, traders, and hedgers will get different treatment. If you are an investor, and you held the stock for a year or more, then you can get the beneficial capital gain rates (e.g. 20% instead of 39.6%).

Qualified dividends are ordinary income but will generally be taxed at capital gains rates under §1(h)(11). Distributions in redemption of your stock are usually treated as sales of stock. Non-dividend distributions (that are not redemptions) will reduce your basis in the stock to zero (no tax due) and past zero will be treated as gain from a sale.

Despite Yahoo's webpage's footnote saying *Close price adjusted for dividends and splits. we can see empirically that the \"\"Adj Close\"\" is only adjusted for splits. For example, consider Siemens from Jan 27, 2017 to Mar 15, 2017: The Adj Close adjusts for splits: On any particular day, the \"\"Adj Close\"\" is equal to the \"\"Close\"\" price divided by the cumulative product of all splits that occurred after that day. If there have been no splits after that day, then the \"\"Adj Close\"\" equals the \"\"Close\"\" price. Since there is a 2-for-1 split on Mar 14, 2017, the Adj Close is half the Close price for all dates from Jan 27, 2017 to Mar 13, 2017. Note that if Siemens were to split again at some time in the future, the Adj Close prices will be readjusted for this future split. For example, if Siemens were to split 3-for-1 tomorrow, then all the Adj Close prices seen above will be divided by 3. The Adj Close is thus showing the price that a share would have traded on that day if the shares had already been split in accordance with all splits up to today. The Adj Close does not adjust for dividends: Notice that Siemens distributed a $1.87 dividend on Feb 02, 2017 and ~$3.74 dividend on Jan 30, 2017. If the Adj Close value were adjusted for these dividends then we should expect the Adj Close should no longer be exactly half of the Close amount. But we can see that there is no such adjustment -- the Adj Close remains (up to rounding) exactly half the Close amount: Note that in theory, the market reacts to the distribution of dividends by reducing the trading price of shares post-dividend. This in turn is reflected in the raw closing price. So in that sense the Adj Close is also automatically adjusted for dividends. But there is no formula for this. The effect is already baked in through the market's closing prices.\"", "title": "" }, { "docid": "98150", "text": "It appears very possible that Google will not have to pay any class C holders the settlement amount, given the structure of the settlement. This is precisely because of the arbitrage opportunity you've highlighted. This idea was mentioned last summer in Dealbreaker. As explained in a Dealbook article: The settlement requires Google to pay the following amounts if, one year from the issuance of the Class C shares, the value diverges according to the following formula: If the C share price is equal to or more than 1 percent, but less than 2 percent, below the A share price, 20 percent of the difference; If the C share price is equal to or more than 2 percent, but less than 3 percent, below the A share price, 40 percent of the difference; If the C share price is equal to or more than 3 percent, but less than 4 percent, below the A share price, 60 percent of the difference; If the C share price is equal to or more than 4 percent, but less than 5 percent, below the A share price, 80 percent of the difference.” If the C share price is equal to or more than 5 percent below the A share price, 100 percent of the difference, up to 5 percent. ... If the Class A shares trade around $450 (after the split/C issuance) and the C shares trade at a 4.5 percent discount during the year (or $429.75 per share), then investors expect a payment of: 80 percent times $450 times 4.5 percent = $16.20. The value of C shares would then be $445.95 ($429.75 plus $16.20). But if this is the new trading value during the year, that’s only a discount of less than 1 percent to the A shares. So no payment would be made. But if no payment is made, we are back to the full discount and this continues ad infinitum. In other words, the value of a stock can be displayed as: {equity value} + {dividend value} + {voting value} + {settlement value} = {total share value} If we ignore dividend and voting values, and ignore premiums and discounts for risk and so forth, then the value of a share is basic equity value plus anticipated settlement payoff. The Google Class C settlement is structured to reduce the payoff as the value converges. And the practice of arbitrage guarantees (if you buy into at least semi-strong EMH) that the price of C shares will be shored up by arbitrageurs that want the payoff. The voting value of GOOGL is effectively zero, since the non-traded Class B shares control all company decisions. So the value of the Class A GOOGL voting is virtually zero for the time being. The only divergence between GOOGL and GOOG price is dividends (which I believe is supposed to be the same) and the settlement payoff. Somebody who places zero value on the vote and who expects dividend difference to be zero should always prefer to buy GOOG to GOOGL until the price is equal, disregarding the settlement. So technically someone is better off owning GOOG, if dividends are the same and market prices are equal, just because the vote is worthless and the nonzero chance of a future settlement payoff is gravy. The arbitrage itself is present because a share that costs (as in the article) $429.75 is worth $445.95 if the settlement pays out at that rate. The stable equilibrium is probably either just before or just after the threshold where the settlement pays off, depending on how reliably arbitrageurs can predict the movement of GOOG and GOOGL. If I can buy a given stock for X but know that it's worth X+1, then I'm willing to pay up to X+1. In the google case, the GOOG stock is worth X+S, where S is an uncertain settlement payment that could be zero or could be substantial. We have six tiers of S (counting zero payoff), so that the price is likely to follow a pattern from X to X+S5 to X-S5+S4 to X-S4+S3, and climbing the tier ladder until it lands in the frontier between X+S1 and X+S0. Every time it jumps into X+S1, people should be willing to pay that new amount for GOOG, so the price moves out of payoff range and into X+S0, where people will only pay X. I'm actually simplifying here, since technically this is all based on future expectations. So the actual price you'd pay is expressed thus: {resale value of GOOG before settlement payoff = X} + ( {expectation that settlement payoff will pay 100% of difference = S5} * {expected nominal difference between GOOG and GOOGL = D} ) + ({S4} * {80% D}) + ({S3} * {60% D}) + ({S2} * {40% D}) + ({S1} * {20% D}) + ({S0} * {0% D}) = {price willing to pay for Class C GOOG = P} Plus you'd technically have to present value the whole thing for the time horizon, since the payoff is in a year. Note that I've shunted any voting/dividend analysis into X. It's reasonable to thing that S5, S4, S3, and maybe S2 are nearly zero, given the open arbitrage opportunity. And we know that S0 times 0% of D is zero. So the real analysis, again ignoring PV, is thus: P = X + (S1*D) Which is a long way of saying: what are the odds that GOOG will happen to be worth no more than 99% of GOOGL on the payoff determination date?", "title": "" }, { "docid": "481169", "text": "Firstly a stock split is easy, for example each unit of stock is converted into 10 units.

To find the new coverage of the option, take the split ratio and multiply by the old coverage (normally 100 shares). To find the new strike price, take the old strike price and divide by the split ratio. Say, for example, you own a call for 100 shares of XYZ with a strike price of $75. Now, if XYZ had a stock split of 2 for 1, then the option would now be for 200 shares with a strike price of $37.50. If, on the other hand, the stock split was 3 for 2, then the option would be for 150 shares with a strike price of $50. So, yes, a 2 for 1 stock split would halve the option strike prices. Also, in case the Investopedia article isn't clear, after a split the options still control 100 shares per contract. Regarding how a dividend affects option prices, I found an article with a good explanation: As mentioned above, dividends payment could reduce the price of a stock due to reduction of the company's assets. It becomes intuitive to know that if a stock is expected to go down, its call options will drop in extrinsic value while its put options will gain in extrinsic value before it happens. Indeed, dividends deflate the extrinsic value of call options and inflate the extrinsic value of put options weeks or even months before an expected dividend payment. Extrinsic value of Call Options are deflated due to dividends not only because of an expected reduction in the price of the stock but also due to the fact that call options buyers do not get paid the dividends that the stock buyers do. This makes call options of dividend paying stocks less attractive to own than the stocks itself, thereby depressing its extrinsic value. How much the value of call options drop due to dividends is really a function of its moneyness. In the money call options with high delta would be expected to drop the most on ex-date while out of the money call options with lower delta would be least affected. If a stock is expected to drop by a certain amount, that drop would already have been priced into the extrinsic value of its put options way beforehand. This is what happens to put options of dividend paying stocks. This effect is again a function of options moneyness but this time, in the money put options raise in extrinsic value more than out of the money put options. This is because in the money put options with delta of close to -1 would gain almost dollar or dollar on the drop of a stock. As such, in the money put options would rise in extrinsic value almost as much as the dividend rate itself while out of the money put options may not experience any changes since the dividend effect may not be strong enough to bring the stock down to take those out of the money put options in the money. So, no, a dividend of $1 will not necessarily decrease an option's price by $1 on the ex-dividend date. It depends on whether it's a call or put option, and whether the option is \"\"in the money\"\" or \"\"out of the money\"\" and by how much.\"", "title": "" }, { "docid": "51066", "text": "\"A 100% stock dividend means that you get one share of the \"\"stock dividend\"\" for every share you own.

However, various stock management policies on the part of the shareholder, brokerage firm or the issuing company can result in you owning fractional shares. Perhaps the most common is a retirement account or other forward-planning account. In such situations, it's the dollar amount that counts; when you deposit money you expect the money to be invested in your chosen mix of mutual funds and other instruments. If the whole-shares rule were absolute, and you wanted to own, for instance, Berkshire Hathaway stock, and you were contributing a few hundred a month, it could take you your entire career of your contributions sitting in a money-market account (essentially earning nothing) before you could buy even one share.

You own 0.001% of the company, and each of your shares is worth $50; the total value of all your shares is $50k. Assume further that the value of the company includes $1B in cash. If the company pays out a dividend of $1B, it will now be only worth $4B. Your shares have just gone down in value by 20%! But, you have a right to 0.001% of the dividend, which equals a $10k cash payment to you. Your personal holdings are now $40k worth of shares, plus $10k in cash. Except for taxes, financial theory states that whether a corporation pays a dividend or not should not impact the value to the individual shareholder. The difference between a regular corporation and a mutual fund, is that the mutual fund is actually a pool of various investments, and it reports a breakdown of that pool to you in a different way. If you own shares directly in a corporation, the dividends you receive are called 'dividends', even if you bought them 1 minute before the ex-dividend date. But a payment from a mutual fund can be divided between, for example, a flow through of dividends, interest, or a return of capital. If you 'looked inside' your mutual fund you when you bought it, you would see that 40% of its value comes from stock A, 20% comes from stock B, etc etc., including maybe 1% of the value coming from a pile of cash the fund owns at the time you bought your units. In theory the mutual fund could set aside the cash it holds for current owners only, but then it would need to track everyone's cash-ownership on an individual basis, and there would be thousands of different 'unit classes' based on timing. For simplicity, the mutual fund just says \"\"yes, when you bought $50k in units, we were 1/3 of the year towards paying out a $10k dividend. So of that $10k dividend, $3,333k of it is assumed to have been cash at the time you bought your shares. Instead of being an actual 'dividend', it is simply a return of capital.\"\" By doing this, the mutual fund is able to pay you your owed dividend [otherwise you would still have the same number of units but no cash, meaning you would lose overall value], without forcing you to be taxed on that payment. If the mutual fund didn't do this separate reporting, you would have paid $50k to buy $46,667k of shares and $3,333k of cash, and then you would have paid tax on that cash when it was returned to you. Note that this does not \"\"falsely exaggerate the investment return\"\", because a return of capital is not earnings; that's why it is reported separately. Note that a 'close-ended fund' is not a mutual fund, it is actually a single corporation. You own units in a mutual fund, giving you the rights to a proportion of all the fund's various investments. You own shares in a close-ended fund, just as you would own shares in any other corporation. The mutual fund passes along the interest, dividends, etc. from its investments on to you; the close-ended fund may pay dividends directly to its shareholders, based on its own internal dividend policy.\"", "title": "" }, { "docid": "565738", "text": "\"If I were in your shoes I'd probably take the Vanguard Total Market fund with Admiral shares, then worry about further diversification when there is more in the account.

This is the \"\"growth versus income\"\" spectrum you may have heard mentioned. In the past, investors took more of their return on investment as dividends -- conceptually, a share of the company's net profits for the year reflecting the share's status as partial ownership.

These days, with growth having been strongly hyped, many companies have shifted much more to the growth model and dividends are often relatively wimpy. Essentially, this assumes that everyone wants the money reinvested and will take their profit by having that increase the value of their shares. Of course that's partly because some percentage of stockholders have been demanding growth at all costs, not always realistically. To address your specific case: No, you probably aren't buying Microsoft because you like its dividend rate; you're buying it in the hope it continues to grow in stock value. But the dividend is a bit of additional return on your investment. And with other companies the tradeoff will be different.

This has the curious effect of giving a member of the index influence proportional to its share price. That is, if a stock costing $100 per share goes up by 1%, that will change the index by 10 times as much as if a stock costing $10 per share goes up by the same 1%. Now look at the price of Google. It's currently trading at just a whisker under $700 per share. Most of the other stocks in the index trade somewhere between $30 and $150, so if Google were included in the index it would contribute between 5 and 20 times the weight of any other stock in the index. That means that relatively small blips in Google's price would completely dominate the index on any given day. Until June of 2014, Apple was in the same boat, with its stock trading at about $700 per share. At that time, Apple split its stock 7:1, and after that its stock price was a little under $100 per share. So, post-split Apple might be a candidate to be included in the Dow the next time they change up the components of the index.

What is the value of such a productive mechanism? Yes, it's capacity to continue producing cash into the future. Under literally any scenario, discounted cash flow is how cash flows at distinct intervals are valued. A company that does not pay dividends now is capable of paying them in the future. Berkshire Hathaway does not pay a dividend currently, but it's cash flows have been reinvested over the years such that it's current cash paying capacity has multiplied many thousands of times over the decades. This is why companies that have never paid dividends trade at higher prices. Microsoft did not pay dividends for many years because the cash was better used developing the company to pay cash flows to investors in later years. A companies value is the sum of it's risk adjusted cash flows in the future, even when it has never paid shareholders a dime. If you had a piece of paper that obligated an entity (such as the government) to absolutely pay you $1,000 20 years from now, this $1,000 cash flows present value could be estimated using Discounted Cash Flow.

So from this simplistic point of view, it is irrelevant whether the stock itself pays dividend or not. There is always the same decision of whether to cut the goose or let it lay a few more eggs that every shareholder has to make it. Paying a dividend is essentially providing a different default choice, but makes little difference with regards to your choices. There is however more to it than simple return on investment arithmetic: As I said, the alternative to paying dividend is reinvesting profits back into the enterprise. If the company decided to pay out dividend, that means they think all the best investing is done, and they don't really have a particularly good idea for what to do with the extra money. Conversely, not paying is like management telling the shareholders, \"\"no we're not done, we're still building our business!\"\". So it can be a way of judging whether the company is concentrating on generating profit or growing itself. Needless to say the, the market is wild and unpredictable and not everyone obeys such assumptions. Furthermore, as I said, you can effectively overrule the decision by increasing or decreasing your position, regardless of whether they have decided to pay dividend to begin with.

This is because in theory, a company can either pay dividends to investors [who can reinvest the funds themselves], or reinvest its capital and earn the same return on that reinvestment [and the shareholder still has the choice to sell a fraction of their holdings, if they prefer to have cash]. That theory may not match reality, because often companies pay or don't pay dividends based on their stage of life. For example, early-stage mining companies often have no free cashflow to pay dividends [they are capital intensive until the mines are operational]. On the other side, longstanding companies may have no projects left that would be a good fit for further investment, and so they pay out dividends instead, effectively allowing the shareholder to decide where to reinvest the money. Therefore, saying \"\"dividend paying\"\"/\"\"growth stock\"\" can be a proxy for talking about the stage of life + risk and return of a company. Saying dividend paying implies \"\"long-standing blue chip company with relatively low capital requirements and a stable business\"\". Likewise \"\"growth stocks\"\" [/ non-dividend paying] implies \"\"new startup company that still needs capital and thus is somewhat unproven, with a chance for good return to match the higher risk\"\". So in theory, dividend payment policy makes no difference. In practice, it makes a difference for two reasons: (1) You will most likely be taxed differently on selling stock vs receiving dividends [Which one is better for you is a specific question relying on your jurisdiction, your current income, and things like what type of stock / how long you hold it]. For example in Canada, if you earn ~ < $40k, your dividends are very likely to have a preferential tax treatment to selling shares for capital gains [but your province and specific other numbers would influence this]. In the United States, I believe capital gains are usually preferential as long as you hold the shares for a long time [but I am not 100% on this without looking it up]. (2) Dividend policy implies differences in the stage of life / risk level of a stock. This implication is not guaranteed, so be sure you are using other considerations to determine whether this is the case. Therefore which dividend policy suits you better depends on your tax position and your risk tolerance.\"", "title": "" }, { "docid": "281841", "text": "\"The amount, reliability and frequency of dividends paid by an ETF other than a stock, such as an index or mutual fund, is a function of the agreement under which the ETF was established by the managing or issuing company (or companies), and the \"\"basket\"\" of investments that a share in the fund represents. Let's say you invest in a DJIA-based index fund, for instance Dow Diamonds (DIA), which is traded on several exchanges including NASDAQ and AMEX. One share of this fund is currently worth $163.45 (Jan 22 2014 14:11 CDT) while the DJIA itself is $16,381.38 as of the same time, so one share of the ETF represents approximately 1% of the index it tracks. The ETF tracks the index by buying and selling shares of the blue chips proportional to total invested value of the fund, to maintain the same weighted percentages of the same stocks that make up the index. McDonald's, for instance, has an applied weight that makes the share price of MCD stock roughly 5% of the total DJIA value, and therefore roughly 5% of the price of 100 shares of DIA. Now, let's say MCD issued a dividend to shareholders of, say, $.20 per share. By buying 100 shares of DIA, you own, through the fund, approximately five MCD shares, and would theoretically be entitled to $1 in dividends. However, keep in mind that you do not own these shares directly, as you would if you spent $16k buying the correct percentage of all the shares directly off the exchange. You instead own shares in the DIA fund, basically giving you an interest in some investment bank that maintains a pool of blue-chips to back the fund shares. Whether the fund pays dividends or not depends on the rules under which that fund was set up. The investment bank may keep all the dividends itself, to cover the expenses inherent in managing the fund (paying fund management personnel and floor traders, covering losses versus the listed price based on bid-ask parity, etc), or it may pay some percentage of total dividends received from stock holdings. However, it will virtually never transparently cut you a check in the amount of your proportional holding of an indexed investment as if you held those stocks directly. In the case of the DIA, the fund pays dividends monthly, at a yield of 2.08%, virtually identical to the actual weighted DJIA yield (2.09%) but lower than the per-share mean yield of the \"\"DJI 30\"\" (2.78%). Differences between index yields and ETF yields can be reflected in the share price of the ETF versus the actual index; 100 shares of DIA would cost $16,345 versus the actual index price of 16,381.38, a delta of $(36.38) or -0.2% from the actual index price. That difference can be attributed to many things, but fundamentally it's because owning the DIA is not the exact same thing as owning the correct proportion of shares making up the DJIA.

Not always by that exact amount for many different reasons (e.g. there are transaction costs if you reinvest, dividend taxes, etc). I have tested that empirically. Now, if all the shareholders choose to reinvest their dividends, will the share price go back up to what it was prior to the dividend? That is an interesting question. The final theoretical price of the company does not need to be that. When a company distributes dividends its liquidity diminish, there is an impact on the balance sheet of the company. If all investors go to the secondary market and reinvest the dividends in the shares, that does not restore the cash in the balance sheet of the company, hence the theoretical real value of the company is different before the dividends. Of course, in practice there is not such a thing as one theoretical value. In reality, if everybody reinvest the dividend, that will put upward pressure over the price of the company and, depending on the depth of the offers, meaning how many orders will counterbalance the upward pressure at the moment, the final price will be determined, which can be higher or lower than before, not necessarily equal. I ask because some efts like SPY automatically reinvest dividends. So what is the effect of this reinvestment on the stock price? Let us see the mechanics of these purchases. When a non distributing ETF receives cash from the dividends of the companies, it takes that cash and reinvest it in the whole basket of stocks that compose the index, not just in the companies that provided the dividends. The net effect of that is a small leverage effect. Let us say you bought one unit of SPY, and during the whole year the shares pay 2% of dividends that are reinvested.

There is an insatiable demand for yield, not just individual investors but investment firms and pension funds that need to generate income to fund retirements for their clients. As more investors purchase the shares of dividend paying securities, the share price goes up. As the share price goes up, the dividend yield goes down. Same for bonds. For example, if a stock pays $1 per year in dividends, and you purchase the shares at $20/each, then your yearly return (not including share price fluctuations) would be 1/20 = 5%. But if you end up having to pay $30 per share, then your yearly return would be 1/30 or 3.3% yield. The more money you invest, the bigger this difference becomes; with $100K invested you'd make about $1.6K more at 5%.

CEFs usually have higher yields than their ETF counterparts.

As the risk free rate of return is expected to finally start slowly rising in 2017 and gradually over time, there should be gradual downward pressure (ie selling) on the prices of dividend stocks and especially bonds meaning you'll get better yields if you wait.

You will still have to pay taxes on the amounts, but that's only due at tax time and it could be very minor (or even a refund) for eligible Canadian dividends. That's because the company has already paid tax on those dividends. In contrast, holding U.S. or any foreign stock that yields dividends in a TFSA will pay 15% withholding tax and it is not recoverable. Correct, but the 15% is a special rate for regular shares and you need to fill out a W8-BEN. Your broker will probably make sure you have every few years. But if you hold the same stock in a non-registered account, this 15% withholding tax can be used as a foreign tax credit? Is this true or not or what are the considerations? That's true but reduces your Canadian tax payable, it's not refundable, so you have to have some tax to subtract it from. Another consideration is foreign dividends are included 100% in income no mater what the character is. That means you pay tax at your highest rate always if not held in a tax sheltered account. Canadian dividends that are in a non-registered account will pay taxes, I presume and I don't know how much, but the amount can be used also as a tax credit or are unrecoverable? What happens in order to take into account taxes paid by the company is, I read also that if you don't want to pay withholding taxes from foreign > dividends you can hold your stock in a RRSP or RRIF? You don't have any withholding taxes from US entities to what they consider Canadian retirement accounts. So TFSAs and RESPs aren't covered. Note that it has to be a US fund like SPY or VTI that trades in the US, and the account has to be RRSP/RRIF. You can't buy a Canadian listed ETF that holds US stocks and get the same treatment. This is also only for the US, not foreign like Europe or Asia. Also something like VT (total world) in the US will have withholding taxes from foreign (Europe & Asia mostly) before the money gets to the US. You can't get that back.

Canada.", "title": "" }, { "docid": "401753", "text": "Actually, share holder value is is better maximised by borrowing, and paying dividends is fairly irrelevant but a natural phase on a mature and stable company. Company finance is generally a balance between borrowing, and money raised from shares. It should be self evident with a little thought that if not now, then in the future, a company should be able to create earnings in excess of the cost of borrowing, or it's not a very valuable company to invest in! In fact what's the point of borrowing if the cost of the interest is greater than whatever wealth is being generated? The important thing about this is that money raised from shares is more expensive than borrowing. If a company doesn't pay dividends, and its share price goes up because of the increasing value of the business, and in your example the company is not borrowing more because of this, then the proportion of the value of the company that is based on the borrowing goes down. So, this means a higher and higher proportion of the finance of a company is provided by the more expensive share holders than the less expensive borrowing, and thus the company is actually providing LESS value to share holders than it might. Of course, if a company doesn't pay a dividend AND borrows more, this is not true, but that's not the scenario in your question, and generally mature companies with mature earnings may as well pay dividends as they aren't on a massive expansion drive in the same way. Now, this relative expense of share holders and borrowing is MORE true for a mature company with stable earnings, as they are less of a risk and can borrow at more favourable rates, AND such a company is LIKELY to be expanding less rapidly than a small new innovative company, so for both these reasons returning money to share holders and borrowing (or maintaining existing lending facilities) maintains a relatively more efficient financing ratio. Of course all this means that in theory, a company should be more efficient if it has no share holders at all and borrows ALL of the money it needs. Yes. In practise though, lenders aren't so keen on that scenario, they would rather have shareholders sharing the risk, and lending a less than 100% proportion of the total of a companies finance means they are much more likely to get their money back if things go horribly wrong. To take a small start up company by comparison, lenders will be leary of lending at all, and will certainly impose high rates if they do, or ask for guarantors, or demand security (and security is only available if there is other investment besides the loan). So this is why a small start up is likely to be much more heavily or exclusively funded by share holders. Also the start up is likely not to pay a dividend, because for a start it's probably not making any profit, but even if it is and could pay a dividend, in this situation borrowing is unavailable or very expensive and this is a rapidly growing business that wants to keep its hands on all the cash it can to accelerate itself. Once it starts making money of course a start up is on its way to making the transition, it becomes able to borrow money at sensible rates, it becomes bigger and more valuable on the back of the borrowing. Another important point is that dividend income is more stable, at least for the mature companies with stable earnings of your scenario, and investors like stability. If all the income from a portfolio has to be generated by sales, what happens when there is a market crash? Suddenly the investor has to pay, where as with dividends, the company pays, at least for a while. If a company's earnings are hit by market conditions of course it's likely the dividend will eventually be cut, but short term volatility should be largely eliminated.", "title": "" }, { "docid": "65295", "text": "The owner of a long futures contract does not receive dividends, hence this is a disadvantage compared to owning the underlying stock.

They can tell you all about the difference between money market, bonds, stocks, managed mutual funds (ripoff!) and index funds. IRA accounts, Roth IRA accounts and taxable accounts are all brokerage accounts. Within them, you can buy any security you want, including index funds. The difference is taxation. Suppose you earn $1000 and choose to invest it however Later you withdraw it and it has grown to $3000. Investing in a taxable account, you pay normal income tax on the $1000. When you later withdraw the $3000, you pay a tax on $2000 of income. If you invested more than a year, it is taxed at a much lower \"\"capital gains\"\" tax rate. With a traditional IRA account, you pay zero taxes on the initial $1000. Later, when you take the money out, you pay normal income tax on the full $3000. If you withdrew it before age 59-1/2, you also pay a 10% penalty ($300). With a Roth IRA account, you pay normal income tax on the $1000. When you withdraw the $3000 later, you pay NOTHING in taxes. Provided you followed the rules. You can invest in almost anything inside these accounts: Money market funds. Terrible return. You won't keep up with the market. Bonds. Low return but usually quite safe. Individual stocks. Good luck. Managed mutual funds. You're paying some genius stock picker to select high performing stocks.

There's no huge staff or genius manager, just some intern making small adjustments every week. As such, the expense ratio is extremely small, like 0.1%.

This may seem odd as a futures contract sounds like you are betting on the future price of the index, but remember that the current price already includes the expectations of future earnings as well! There is actually a fairly simple formula for the price of a futures contract (note the link is for forward contracts which are very similar but slightly more simple to understand). Note, that if you are given the current price of the underlying the futures price depends essentially only on the interest rate and the dividends paid during the length of the futures contract. In this case the dividend rate for the S&P500 is higher than the prevailing interest rate so the futures price is lower than the current price. It is slightly more complicated than this as you can see from the formula, but that is essentially how it works. Note, this is why people use futures contracts to mimic other exposures. As the price of the future moves (pretty much) in lockstep with the underlying and sometimes using futures to hedge exposures can be cheaper than buying etfs or using swaps. Edit: Example of the effect of dividends on futures prices For simplicity, let's imagine we are looking at a futures position on a stock that has only one dividend (D) in the near term and that this dividend happens to be scheduled for the day before the futures' delivery date. To make it even more simple lets say the price of the stock is fairly constant around a price P and interest rates are near zero. After the dividend, we would expect the price of the stock to be P' ~ P - D as if you buy the stock after the dividend you wouldn't get that dividend but you still expect to get the rest of the value from additional future cash flows of the company. However, if we buy the futures contract we will eventually own the stock but only after the dividend happens. Since we don't get that dividend cash that the owners of the stock will get we certainly wouldn't want to pay as much as we would pay for the stock (P). We should instead pay about P' the (expected) value of owning the stock after that date. So, in the end, we expect the stock price in the future (P') to be the futures' price today (P') and that should make us feel a lot more comfortable about what we our buying. Neither owning the stock or future is really necessarily favorable in the end you are just buying slightly different future expected cash flows and should expect to pay slightly different prices.", "title": "" }, { "docid": "170318", "text": "It depends on your investment profile but basically, dividends increase your taxable income. Anyone making an income will effectively get 'lower returns' on their investments due to this effect. If you had the choice between identical shares that either give a dividend or don't, you'll find that stock that pays a dividend has a lower price, and increases in value more slowly than stock that doesn't. (all other things being equal) There's a whole bunch of economic theory behind this but in short, the current stock price is a measure of how much the company is worth combined with an estimation of how much it will be worth in the future (NPV of all future dividends is the basic model). When the company makes profit, it can keep those profits, and invest in new projects or distribute a portion of those profits to shareholders (aka dividends). Distributing the value to shareholders reduces the value of the company somewhat, but the shareholders get the money now. If the company doesn't give dividends, it has a higher value which will be reflected in a higher stock price. So basically, all other things being equal (which they rarely are, but I digress) the price and growth difference reflects the fact that dividends are paying out now. (In other words, if you wanted non-dividend shares you could get them by buying dividend shares and re-investing the dividend as new shares every time there was a payout, and you could get dividend-share like properties by selling a percentage of non-dividend shares periodically). Dividend income is taxable as part of your income right away, however taxes on capital gains only happen when you sell the asset in question, and also has a lower tax rate. If you buy and hold Berkshire Hatheway, you will not have to pay taxes on the gains you get until you decide to sell the shares, and even then the tax rate will be lower. If you are investing for retirement, this is great, since your income from other sources will be lower, so you can afford to be taxed then. In many jurisdictions, income from capital gains is subject to a different tax rate than the rest of your income, for example in the US for most people with money to invest it's either 15% or 20%, which will be lower than normal income tax would be (since most people with money to invest would be making enough to be in a higher bracket). Say, for example, your income now is within the 25% bracket. Any dividend you get will be taxed at that rate, so let's say that the dividend is about 2% and the growth of the stock is about 4%. So, your effective growth rate after taxation is 5.5% -- you lose 0.5% from the 25% tax on the dividend. If, instead, you had stock with the same growth but no dividend it would grow at a rate of 6%. If you never withdrew the money, after 20 years, $1 in the dividend stock would be worth ~$2.92 (1.055^20), whereas $1 in the non-dividend stock would be worth ~$3.21 (1.06^20). You're talking about a difference of 30 cents per dollar invested, which doesn't seem huge but multiply it by 100,000 and you've got yourself enough money to renovate your house purely out of money that would have gone to the government instead. The advantage here is if you are saving up for retirement, when you retire you won't have much income so the tax on the gains (even ignoring the capital gains effect above) will definitely be less then when you were working, however if you had a dividend stock you would have been paying taxes on the dividend, at a higher rate, throughout the lifetime of the investment. So, there you go, that's what Mohnish Pabrai is talking about. There are some caveats to this. If the amount you are investing isn't large, and you are in a lower tax bracket, and the stock pays out relatively low dividends you won't really feel the difference much, even though it's there. Also, dividend vs. no dividend is hardly the highest priority when deciding what company to invest in, and you'll practically never be able to find identical companies that differ only on dividend/no dividend, so if you find a great buy you may not have a choice in the matter. Also, there has been a trend in recent years to also make capital gains tax progressive, so people who have a higher income will also pay more in capital gains, which negates part of the benefit of non-dividend stocks (but doesn't change the growth rate effects before the sale). There are also some theoretical arguments that dividend-paying companies should have stronger shareholders (since the company has less capital, it has to 'play nice' to get money either from new shares or from banks, which leads to less risky behavior) but it's not so cut-and-dried in real life.", "title": "" }, { "docid": "511559", "text": "\"While nothing is guaranteed - any stock market or country could collapse tomorrow - if you have a fairly long window (15+ years is certainly long), ETFs are likely to earn you well above inflation. Looking at long term ETFs, you typically see close to 10% annual growth over almost any ten year period in the US, and while I don't know European indexes, they're probably well above inflation at least. The downside of ETFs is that your money is somewhat less liquid than in a savings account, and any given year you might not earn anything - you easily could lose money in a particular year. As such, you shouldn't have money in ETFs that you expect to use in the next few months or year or even a few years, perhaps. But as long as you're willing to play the long game - ie, invest in ETF, don't touch it for 15 years except to reinvest the dividends - as long as you go with someone like Vanguard, and use a very low expense ratio fund (mine are 0.06% and 0.10%, I believe), you are likely in the long term to come out ahead. You can diversify your holdings - hold 10% to 20% in bond funds, for example - if you're concerned about risk; look at how some of the \"\"Target\"\" retirement funds allocate their investments to see how diversification can work [Target retirement funds assume high risk tolerance far out and then as the age grows the risk tolerance drops; don't invest in them, but it can be a good example of how to do it.] All of this does require a tolerance of risk, though, and you have to be able to not touch your funds even if they go down - studies have repeatedly shown that trying to time the market is a net loss for most people, and the best thing you can do when your (diverse) investments go down is stay neutral (talking about large funds here and not individual stocks). I think this answers 3 and 4. For 1, share price AND quantity matter (assuming no splits). This depends somewhat on the fund; but at minimum, funds must dividend to you what they receive as dividends. There are Dividend focused ETFs, which are an interesting topic in themselves; but a regular ETF doesn't usually have all that large of dividends. For more information, investopedia has an article on the subject. Note that there are also capital gains distributions, which are typically distributed to help offset capital gains taxes that may occur from time to time with an ETF. Those aren't really returns - you may have to hand most or all over to the IRS - so don't consider distributions the same way. The share price tracks the total net asset value of the fund divided by the number of shares (roughly, assuming no supply/demand split). This should go up as the stocks the ETF owns go up; overall, this is (for non-dividend ETFs) more often the larger volatility both up and down. For Vanguard's S&P500 ETF which you can see here, there were about $3.50 in dividends over 2014, which works out to about a 2% return ($185-$190 share price). On the other hand, the share price went from around $168 at the beginning of 2014 to $190 at the end of 2014, for a return of 13%. That was during a 'good' year for the market, of course; there will be years where you get 2-3% in dividends and lose money; in 2011 it opened at 116 and closed the year at 115 (I don't have the dividend for that year; certainly lower than 3.5% I'd think, but likely nonzero.) The one caveat here is that you do have stock splits, where they cut the price (say) in half and give you double the shares. That of course is revenue neutral - you have the same value the day after the split as before, net of market movements. All of this is good from a tax point of view, by the way; changes in price don't hit you until you sell the stock/fund (unless the fund has some capital gains), while dividends and distributions do. ETFs are seen as 'tax-friendly' for this reason. For 2, Vanguard is pretty good about this (in the US); I wouldn't necessarily invest monthly, but quarterly shouldn't be a problem. Just pay attention to the fees and figure out what the optimal frequency is (ie, assuming 10% return, what is your break even point). You would want to have some liquid assets anyway, so allow that liquid amount to rise over the quarter, then invest what you don't immediately see a need to use. You can see here Vanguard in the US has no fees for buying shares, but has a minimum of one share; so if you're buying their S&P500 (VOO), you'd need to wait until you had $200 or so to invest in order to invest additional funds.\"", "title": "" }, { "docid": "163354", "text": "Victor, Yes the drop in price does completely cancel the dividend at first. However, as others have noted, there are other forces working on the price as well. If dividends were pointless then the following scenario would be true: Let's assume, hypothetically, two identical stocks, only one of which pays a 2% annual dividend quarterly. At the end of the year we would expect the share price of the dividend stock to be 2% lower than the non-dividend stock. And an equal investment in both stocks would yield exactly the same amount of money. So that is a hypothetical, and here is real market example: I compared, i.e. took the ratio of Vanguard's S&P 500 ETF (VOO) closing price to the S&P 500 Index closing price from sep 9, (2010-2014), after accounting for the VOO 2013 split. The VOO pays a quarterly dividend(about 2%/year), the S&P is an index, hence no dividend. The VOO share price, reduced each quarter by the dividend, still grew more than the S&P each year except 2012 to 2013, but looking at the entire 4yr period the VOO share price grew 80.3987% while S&P grew 80.083% (1/3 of 1% more for VOO). VOO does drop about 1/2% relative to S&P on every ex date, but obviously it makes it up. There are other forces working on VOO. VOO is trade-able, therefore subject to supply/demand pressures, while the S&P 500 is not.

Here's how I've reconciled it in my mind. Why should we agree that a stock is worth anything? After all, if I purchase a share of said company, I own some small percentage of all of its assets, like land, capital equipment, accounts receivable, cash and securities holdings, etc., as others have pointed out. Notionally, that seems like it should be \"\"worth\"\" something. However, that doesn't give me the right to lay claim to them at will, as I'm just a (very small) minority shareholder. The old adage says that \"\"something is only worth what someone is willing to pay you for it.\"\" That share of stock doesn't actually give me any liquid control over the company's assets, so why should someone else be willing to pay me something for it? As you noted, one reason why a stock might be attractive to someone else is as a (potentially tax-advantaged) revenue stream via dividends. Especially in this low-interest-rate environment, this might well exceed that which I might obtain in the bond market. The payment of income to the investor is one way that a stock might have some \"\"inherent value\"\" that is attractive to investors. As you asked, though, what if the stock doesn't pay dividends? As a small shareholder, what's in it for me? Without any dividend payments, there's no regular method of receiving my invested capital back, so why should I, or anyone else, be willing to purchase the stock to begin with? I can think of a couple reasons: Expectation of a future dividend. You may believe that at some point in the future, the company will begin to pay a dividend to investors. Dividends are paid as a percentage of a company's total profits, so it may make sense to purchase the stock now, while there is no dividend, banking on growth during the no-dividend period that will result in even higher capital returns later. This kind of skirts your question: a non-dividend-paying stock might be worth something because it might turn into a dividend-paying stock in the future. Expectation of a future acquisition. This addresses the original premise of my argument above. If I can't, as a small shareholder, directly access the assets of the company, why should I attribute any value to that small piece of ownership? Because some other entity might be willing to pay me for it in the future. In the event of an acquisition, I will receive either cash or another company's shares in compensation, which often results in a capital gain for me as a shareholder. If I obtain a capital gain via cash as part of the deal, then this proves my point: the original, non-dividend-paying stock was worth something because some other entity decided to acquire the company, paying me more cash than I paid for my shares. They are willing to pay this price for the company because they can then reap its profits in the future. If I obtain a capital gain via stock in as part of the deal, then the process restarts in some sense. Maybe the new stock pays dividends. Otherwise, perhaps the new company will do something to make its stock worth more in the future, based on the same future expectations. The fact that ownership in a stock can hold such positive future expectations makes them \"\"worth something\"\" at any given time; if you purchase a stock and then want to sell it later, someone else is willing to purchase it from you so they can obtain the right to experience a positive capital return in the future.

Dividends are simply corporate payouts made to the shareholders of the company. A company often decides to pay dividends because they have excess cash on hand and choose to return it to shareholders by quarterly payouts instead of stock buy backs or using the money to invest in new projects. I'm not exactly sure what you mean by \"\"dividend yield traps.\"\" If a company has declared an dividend for the upcoming quarter they will almost always pay. There are exceptions, like what happened with BP, but these exceptions are rare. Just because a company promises to pay a dividend in the approaching quarter does not mean that it will continue to pay a dividend in the future. If the company continues to pay a dividend in the future, it may be at a (significantly) different amount.

It appears to be based on the assumption that the price of a stock is equal to the value of the assets of a company divided by the total number of shares. But that simply isn't true. You don't even need to do any in-depth analysis to prove it. Just look at share prices over a few days. You should easily be able to find stocks whose price varied wildly. If, say, a company becomes the target of a federal investigation, the share price will plummet the day the announcement is made. Did the company's assets really disappear that day? No. What's happened is that the company's long term prospects are now in doubt. Or a company announces a promising new product. The share price shoots up. They may not have sold a single unit of the new product yet, they haven't made a dollar. But their future prospects now look improved. Many factors go into determining a stock price. Sure, total assets is a factor. But more important is anticipated future earning. I think a very simple case could be made that if a stock never paid any dividends, and if everyone knew it would never pay any dividends, that stock is worthless. The stock will never produce any profit to the owner. So why should you be willing to pay anything for it? One could say, The value could go up and you could sell at a profit. But on what basis would the value go up? Why would investors be willing to pay larger and larger amounts of money for an asset that produces zero income? Update I think I understand the source of the confusion now, so let me add to my answer. Suppose that a company's stock is selling for, say, $10. And to simplify the discussion let's suppose that there is absolutely nothing affecting the value of that stock except an expected dividend. The company plans to pay a dividend on a specific date of $1 per share. This dividend is announced well in advance. Everyone knows that it will be paid, and everyone is extremely confidant that in fact the company really will pay it -- they won't run out of money or any such. Then in a pure market, we would expect that as the date of that dividend approaches, the price of the stock would rise until the day before the dividend is paid, it is $11. Then the day after the dividend is paid the price would fall back to $10. Why? Because the person who owns the stock on the \"\"dividend day\"\" will get that $1. So if you bought the stock the day before the dividend, the next day you would immediately receive $1. If without the dividend the stock is worth $10, then the day before the dividend the stock is worth $11 because you know that the next day you will get a $1 \"\"refund\"\". If you buy the stock the day after the dividend is paid, you will not get the $1 -- it will go to the person who had the stock yesterday -- so the value of the stock falls back to the \"\"normal\"\" $10. So if you look at the value of a stock immediately after a dividend is paid, yes, it will be less than it was the day before by an amount equal to the dividend. (Plus or minus all the other things that affect the value of a stock, which in many cases would totally mask this effect.) But this does not mean that the dividend is worthless. Just the opposite. The reason the stock price fell was precisely because the dividend has value. BUT IT ONLY HAS VALUE TO THE PERSON WHO GETS IT. It does me no good that YOU get a $1 dividend. I want ME to get the money. So if I buy the stock after the dividend was paid, I missed my chance. So sure, in the very short term, a stock loses value after paying a dividend. But this does not mean that dividends in general reduce the value of a stock. Just the opposite. The price fell because it had gone up in anticipation of the dividend and is now returning to the \"\"normal\"\" level. Without the dividend, the price would never have gone up in the first place. Imagine you had a company with negligible assets. For example, an accounting firm that rents office space so it doesn't own a building, its only tangible assets are some office supplies and the like. So if the company liquidates, it would be worth pretty much zero. Everybody knows that if liquidated, the company would be worth zero. Further suppose that everyone somehow knows that this company will never, ever again pay a dividend. (Maybe federal regulators are shutting the company down because it's products were declared unacceptably hazardous, or the company was built around one genius who just died, etc.) What is the stock worth? Zero. It is an investment that you KNOW has a zero return. Why would anyone be willing to pay anything for it? It's no answer to say that you might buy the stock in the hope that the price of the stock will go up and you can sell at a profit even with no dividends. Why would anyone else pay anything for this stock? Well, unless their stock certificates are pretty and people like to collect them or something like that. Otherwise you're supposing that people would knowingly buy into a pyramid scheme. (Of course in real life there are usually uncertainties. If a company is dying, some people may believe, rightly or wrongly, that there is still hope of reviving it. Etc.) Don't confuse the value of the assets of a company with the value of its stock. They are related, of course -- all else being equal, a company with a billion dollars in assets will have a higher market capitalization than a company with ten dollars in assets. But you can't calculate the price of a company's stock by adding up the value of all its assets, subtracting liabilities, and dividing by the number of shares. That's just not how it works. Long term, the value of any stock is not the value of the assets but the net present value of the total future expected dividends.

SPY pays out quarterly the dividends it receives (after deducting fees and expenses). This is typical of ETFs.

If you purchase a share for $100, and then later sell it for $150, you should note that there is always someone that purchases the same share for $150. So, you get $150 immediately, but somebody else has to pay $150 immediately. So, investors collectively did not receive any money from the transaction. (Yes, share repurchase can be used instead of dividends, but it can be considered really another form of paying dividends.) The fair value of a stock is the discounted value of all future dividends the stock pays. It is so simple! This shows why dividends are important. Somebody might argue that many successful companies like Berkshire Hathaway do not pay dividend. Yes, it is true that they don't pay dividend now but they will eventually have to start paying dividend. If they reinvest potential dividends continuously, they will run out of things to invest in after several hundred years has passed. So, even in this case the value of the stock is still the discounted value of all future dividends. The only difference is that the dividends are not paid now; the companies will start to pay the dividends later when they run out of things to invest in. It is true that in theory a stock could pay an unsustainable amount of dividend that requires financing it with debt. This is obviously not a good solution. If you see a company that pays dividend while at the same time obtaining more cash from taking more debt or from share issues, think twice whether you want to invest in such a company. What you need to do to valuate companies fairly is to estimate the amount of dividend that can sustain the expected growth rate. It is typically about 60% of the earnings, because a part of the earnings needs to be invested in future growth, but the exact figure may vary depending on the company. Furthermore, to valuate a company, you need the expected growth rate of dividends and the discount rate. You simply discount all future dividends, correcting them up by the expected dividend growth rate and correcting them down by the discount rate.", "title": "" }, { "docid": "393693", "text": "For the Roth the earnings: interest, dividends, capital gains distributions and capital gains are tax deferred.

If the loan's rate is low enough, then I can invest the cash in something fairly low-risk, and make more money than I pay in interest. The interest rate has to be pretty low, say below 4% or so. My auto loan is low enough and my home loan is low enough if you count the tax deduction. Obviously you have to invest in something riskier than cash here, though. And consider taxes, which lower the rate you're paying on a home loan, but also lower the returns you're getting on any bonds you invest in. Liquidity and flexibility. If I have N thousands in cash instead of tied up in my house, then I could use that money to survive many months of unemployment for example, or handle any other emergency. But if you become unemployed or have some other emergency, it will be too late to get a home loan. Credit rating. It's good to use some credit, just so you can get more if you need it. But this isn't a reason to take a particular loan, just a reason to have some kind of credit card or loan. Budgeting. When budgeting, it's best to think of expenses such as cars and houses in terms of a monthly cost, so you can see how they nudge out or allow other spending. (When negotiating with a car dealer, of course, use total cost so you don't get screwed by him messing with interest rates.) I wouldn't take a loan just to ease the budgeting (you can always manually \"\"amortize\"\") but it's a nice side effect. For credit cards, there are more buyer protections and you get a nice transaction log (again useful in budgeting). Also you don't have to carry around cash, or worry about your checking account balance. So credit cards are just convenient. But even though my card has a very low rate, it isn't low enough that I want to keep a balance month-to-month, so I don't use credit cards to actually borrow money.\"", "title": "" }, { "docid": "478710", "text": "\"You can find out the most money they will loan you for a car loan when you approach your current bank/credit union.

There are several dangers with getting loan estimates, they may be willing to lend you more than you can actually handle. They think you can afford it, but maybe you can't. They may also have a loan with a longer term, which does bring the monthly cost down, but exposes you to being upside down on the loan. You then use this a a data point when looking at other lenders. The last place you look is the auto dealer. They will be trying to pressure you on both the loan and the price, that is not the time to do doing complex mental calculations. The Suntrust web page was interesting, it included the quote: The lowest rate in each range is for LightStream's unsecured auto loan product and requires that you have an excellent credit profile. It also induced the example the rate of 2.19% - 4.24% for a 24 to 36 month loan of $10,000 to $24,999 for a used car purchased from a dealer.

However, we find individuals with excellent credit usually share the following characteristics: Finally, it should be noted again that each individual situation is different and that we make our credit judgment based on the specific facts of that situation.

Generally, if you've gotten approved for financing, that will come in the form of another credit card account (many contracting and plumbing companies will do this in hopes you will use the card for future purchases) or a bank loan account (more common for auto and home loans). With the credit card account, you might be able to perform a balance transfer, but there are usually fees associated with that. For bank loan accounts, you probably can't pay that off with a credit card. You'll need to transfer money to the account via ACH or send in a check.

A mortgage is nothing but a secured loan against your home. You can open a HELOC and treat it as a negative-equity bank-account. Note that both a mortgage and a HELOC tend to have significant up-front or administrative costs attached to them. It costs the loaning institution some money to ensure they are in a safe position, and they will want to pass it on to you. They don't want you taking out such a loan and not using it. On the other hand, the interest rates on such a loan are often much lower than interest rates on other loans. If you have a reliable source of significant income, getting a completely unsecured line of credit may be possible with a rate only a few percentage points higher than a HELOC without having to pay a cent in fees. The bank doesn't have to appraise your home or ensure ownership before such a loan, just assess income (which is easy, especially if you have a regular paycheck auto-deposited into an account at the same branch; toss in some signatures from your employer and good to go). If that is feasible, you could end up with a lower rate. Withdraw from the line of credit, pay off your other loans, then work to repay the line of credit. If an unsecured line of credit has a rate 1-3% higher than a secured one, and you are borrowing 5000$ against it and pay it off over 2 years, the total interest you would save from a secured line is about 50$-150$.

Paying cash for a car is recommended over paying credit for example. For a house, getting a mortgage is recommended. Says who? These rules of thumb hide the actual equations behind them; they should be understood as heuristics, not as the word of god. The Basics The basic idea is, if you pay for something upfront, you pay some fixed cost, call it X, where as with a loan you need to pay interest payments on X, say %I, as well as at least fixed payments P at timeframe T, resulting in some long term payment IX. Your Assumption To some, this obviously means upfront payments are better than interest payments, as by the time the loan is paid off, you will have paid more than X. This is a good rule of thumb (like Newtonian's equations) at low X, high %I, and moderate T, because all of that serves to make the end result IX > X. Counter Examples Are there circumstances where the opposite is true? Here's a simple but contrived one: you don't pay the full timeframe. Suppose you die, declare bankruptcy, move to another country, or any other event that reduces T in such a way that XI is less than X. This actually is a big concern for older debtors or those who contract terminal illnesses, as you can't squeeze those payments out of the dead. This is basically manipulating the whole concept. Let's try a less contrived example: suppose you can get a return higher than %I. I can currently get a loan at around %3 due to good credit, but index funds in the long run tend to pay %4-%5. Taking a loan and investing it may pay off, and would be better than waiting to have the money, even in some less than ideal markets. This is basically manipulating T to deal with IX. Even less contrived and very real world, suppose you know your cash flow will increase soon; a promotion, an inheritance, a good market return. It may be better to take the loan now, enjoy whatever product you get until that cash flows in, then pay it all off at once; the enjoyment of the product will make the slight additional interest worth it. This isn't so much manipulating any part of the equation, it's just you have different goals than the loan. Home Loan Analysis For long term mortgages, X is high, usually higher than a few years pay; it would be a large burden to save that money for most people. %I is also typically fairly low; P is directly related to %I, and the bank can't afford to raise payments too much, or people will rent instead, meaning P needs to be affordable. This does not apply in very expensive areas, which is why cities are often mostly renters. T is also extremely long; usually mortgages are for 15 or 30 years, though 10 year options are available. Even with these shorter terms, it's basically the longest term loan a human will ever take. This long term means there is plenty of time for the market to have a fluctuation and raise the investments current price above the remainder of the loan and interest accrued, allowing you to sell at a profit. As well, consider the opportunity cost; while saving money for a home, you still need a place to live. This additional cost is comparable to mortgage payments, meaning X has a hidden constant; the cost of renting. Often X + R > IX, making taking a loan a better choice than saving up. Conclusion \"\"The general advice\"\" is a good heuristic for most common human payments; we have relatively long life spans compared to most common payments, and the opportunity cost of not having most goods is relatively low. However, certain things have a high opportunity cost; if you can't talk to HR, you can't apply for jobs (phone), if you can't get to work, you can't eat (car), and if you have no where to live, it's hard to keep a job (house). For things with high opportunity costs, the interest payments are more than worth it.\"", "title": "" }, { "docid": "515615", "text": "If your credit card's interest rates are not more than your 35% (25% for your tax bracket and 10% penalty), there is no way I would consider this. If you boil it down to the numbers, you are asking whether you should borrow money at a 35% interest to pay off your credit cards. I would say Absolutely Not! $20K of auto loans which equal $1100 a month in payments. Also we purchased a car for me a year ago which is 375 a month. Probably shouldn't have done it but the car I was driving was on it's last leg. Where is the $805 difference going? You've got to make sacrifices, and right now you are leaning towards sacrificing your future for your present. It would take years of Large Contributions to make up for the money lost in early withdraw penalties and taxes, not to mention the loss in growth these accounts would have been earning if left alone. This plan is similar to saying you want to spend $60k to pay off $40k. Don't do it! If it was me, I'd get a couple $3,000 cars. That should free up at least $600 a month and reduces your debt by $14k. I'd also pull my child out of private school unless there is really no public option, which based upon your refusal to consider selling your house, I image there's a decent public school near your neighborhood. That's an extra $500 a month. Next, I'd sell anything that I could through craigslist or garage sales. I'd get on a written budget and the envelope system, to make sure you are really as 'tight' as you are presenting in your question. Hating Debt is a great motivator, but you shouldn't let it lead you to make even bigger financial mistakes. I think you started doing well and got promotions and did what almost everyone else does; you increased your standard of living. No matter what you choose to do, you will never build your retirement or have financial stability without living on a budget and spending less than you make. Maybe attacking this debt the old-fashioned way will give you the tools you need to gain financial stability long-term. Updated to address calculations Assuming 18% CC interest and 10% IRA Growth. And always spending at least $1500 on CC debt until it's gone, then $1,500 back into retirement after that. If you continued paying $1,500 a month the credit cards would take about 71 months to pay off. In that time, you'd spend a total of $106,500 on the debt. Your plan would spend $60k upfront to reduce the debt by $40k. The new balance of $25k would be paid off in 20 months and would cost $30k total. Total cost on your plan would be $90k. Your plan pays $16.5k less in total, and it would be 51 months quicker. However, you would have no retirement at age 40. If you then saved $1500 a month in retirement, you would catch up to the $70k loss in your IRA at age 49 (I'm including growth in both accounts to calculate this). If you had instead just left the IRA alone, you'd be done with the CCs at age 44. If after age 44, you put in $1500 month into retirement your plan would never catch up to this plan.

Length/volume of credit history. This is a combination of how many accounts appear in your history along with how long they have been open. Having a series of accounts that were maintained in good standing looks better than only having one. Maintaining an account in good standing for a prolonged period (3+ years) is better than a bunch of short term items. \"\"Ideally\"\" your credit history should contain a mix of term loans that were paid per contract and a few (1?) revolving account that shows ongoing use. The goal is to show that you can handle ongoing obligations responsibly, and manage multiple things at the same time. Utilization. Or how much you currently owe vs how much people have agreed to lend you. Being close to your limits raises questions about whether or not you can really handle the additional debt. Having large availability raises questions about whether you would be able to handle it if you suddenly maxed things out. Finding the correct middle point can be challenging, the numbers I have seen thrown around most by the \"\"experts\"\" is 20-30% utilization. Recent Activity. Or how much new debt have you taken on? If someone is opening lots of new accounts it raises red flags. Shopping around for a deal on a auto loan or mortgage before settling on one is fine. Opening 5 new credit lines in the past 6 months, probably going to knock you down a bit. One of the concerns here is have you had the accounts long enough to demonstrate that you will be able to handle them in the long term. One route that was suggested to me in my early years was to go take out a 6mo loan from a bank, and just place the money in a CD while I made the payments. Then repeat with a longer term. Worst case, you can cash out the CD to pay off the loan in an emergency, but otherwise it helps show the type of history they are looking for. All that said, I have to agree with Pete B's answer.

It's called a \"\"Line of credit\"\" (LOC). I have two them, one for my business, and one for me personally. (Why does this question exist:) Is it an 30-year loan or a 10-year loan? As you mentioned, the concept of term doesn't exist for these types of loans. As long as I pay the interest and don't go over the max of my credit limit, I could keep the money indefinitely. Due to this, lines of credit almost always have a variable interest rate. (In the US they are tied to the Prime rate.) (Why does this question exist:) If you pay extra, do you want the extra to go toward the interest or toward the principal? Again, this concept also doesn't exist with a LOC. There is a minimum payment that you must make each month, but there is nothing that prevents you from making the minimum payment and then immediately taking the exact payment you made back out again. Of course this increases the total you owe, and eventually you would hit your maximum credit limit and would no longer be able to take the full payment back out. Years ago I maxed out my business line and didn't have enough money to make the payment so my bank was nice enough to raise my limit for me (so I could take enough out to make the payment), but if I did that multiple times I'm sure they would have eventually said no. Fortunately my clients finally paid me and I paid off the line, but I still keep the LOC today even though I rarely use it. By the way, beyond traditional LOCs, they also exist in other forms, both secured and unsecured. A common secured product in the US is a 2nd lien holder to a home (the first being the mortgage), called a HELOC (Home Equity Line Of Credit). Many banks also offer unsecured LOCs on a checking account which they sometimes call \"\"overdraft protection\"\". Update: based on a comment to this answer, I now realize that the full question now becomes something similar to: Given that the Line of Credit loan model exists, why aren't all loans like this? or, refining it further: What advantages do other loan types have over the Line of Credit model, specifically finite term loans? A main advantage of a term loan over a line of credit is that the bank knows when they will get the money back. If every loan a bank made was a LOC product, and no one ever paid it back, then they'd eventually run out of money. That's obviously an oversimplification but the principle (pun intended) holds. To prevent this the bank would have to call due the loan, and doing this usually leaves customers angry. Years ago I had a business LOC with a bank that discontinued their business LOC product, and called every customer's loan due. I had a balance and they offered to convert it to a 5 year term loan, which I did, but I was so mad at them that I switched banks and paid off the term loan shortly after. Another advantage of a term loan is it forces the customer to be a little more responsible. Lines of credit can be dangerous for those that misuse it because if the amount owed is driven up due to bad behavior, there is nothing to force the bad behavior to stop. A perfect example of this can be found with governments. Some governments borrow money until their line of credit is used up, and then they just keep increasing their credit limit. There is no incentive for the officials in charge of the government to stop doing this because it isn't even their money. If those lines of credits were converted to term loans, the government would be forced to increase revenue and/or decrease expenses, which is the only way to get out of debt.

I'd never keep track to this level of detail if I were using cash. 3) Many cards offer reward programs that can be used for cash back. 4) It helps maintain my credit rating for those times I NEED to buy something and pay it off over time (car, house, etc.) 5) Not so much an issue for me personally, but for people that live paycheck to paycheck, it might help to time your cash outflows to match up with your inflows. For a business, I think it is mostly a cash flow issue. That is, in a lot of B2B type businesses customers can pay very slowly (managing their own cash flows).

Most people who use a 529 plan either purchase years of tuition via lump sum, when the child is young; or they put aside money on a regular basis that will grow tax deferred/tax free. Some states do give a tax break when the contribution is made by a state taxpayer into a plan run by the state. The long term plans generally use a risk profile that starts off heavily weighted in stock when the child is young, and becomes more fixed income as the child reaches their high school years. The idea is to protect the fund from big losses when there is no time to recover. If you choose the plan with the least risk the issue is that the amount of gains that are being protected from federal tax is small. If you pick a more aggressive plan the risk is that the losses could be larger than the state tax savings. Look at some of the other tax breaks for tuition to see if you qualify Credits An education credit helps with the cost of higher education by reducing the amount of tax owed on your tax return. If the credit reduces your tax to less than zero, you may get a refund. There are two education credits available: the American Opportunity Tax Credit and the Lifetime Learning Credit. Who Can Claim an Education Credit? There are additional rules for each credit, but you must meet all three of the following for either credit: If you’re eligible to claim the lifetime learning credit and are also eligible to claim the American opportunity credit for the same student in the same year, you can choose to claim either credit, but not both.

The qualified expenses must be for higher education. The tuition and fees deduction can reduce the amount of your income subject to tax by up to $4,000. This deduction, reported on Form 8917, Tuition and Fees Deduction, is taken as an adjustment to income. This means you can claim this deduction even if you do not itemize deductions on Schedule A (Form 1040).

In other words, if employee stock option rights are surrendered to an employer for cash or an in-kind payment, then (subject to new subsections 110(1.1) and (1.2)) the employer may deduct the payment but the employee cannot claim the stock option deduction. Conversely, where an employer issues securities pursuant to an employee’s exercise of stock options, the employer can not deduct an amount in respect of the issuance, but the employee may be eligible to claim a deduction under paragraph 110(1)(d).

From what I can tell, if you opted for a cash payment (or if your plan only allows for such), then the part I emphasized comes into play. Essentially, if conditions were such that your employer could claim a deduction on their corporate income tax return for the compensation paid to you as part of the plan, then you are not also able to claim a similar deduction on your personal income tax return. The money received in that manner is effectively taxed in your hands the same as any bonus employment income would be; i.e. it isn't afforded tax treatment equivalent to capital gains income.

First, you need to understand that there will be taxes withheld from your paycheck, but the amount that they withhold is simply a guess. You might pay too much or too little tax during the year. After the year is over, you'll send in a tax return form that calculates the correct tax amount. If you have paid too little over the year, you'll have to send in the rest, but if you've paid too much, you'll get a refund. There are complicated formulas on how much tax the employer withholds from your paycheck, but in general, if you don't have extra income elsewhere that you need to pay tax on, you'll probably be close to breaking even at tax time. When you get your paycheck, the first thing that will be taken off is FICA, also called Social Security, Medicare, or the Payroll tax. This is a fixed 7.65% that is taken off the gross salary. It is not refundable and is not affected by any allowances or deductions, and does not come in to play at all on your tax return form. There are optional employee benefits that you might need to pay a portion of if you are going to take advantage of them, such as health insurance or retirement savings. Some of these deductions are paid with before-tax money, and some are paid with after tax money. The employer will calculate how much money they are supposed to withhold for federal and state taxes (yes, California has an income tax), and the rest is yours. At tax time, the employer will give you a form W-2, which shows you the amount of your gross income after all the before-tax deductions are taken out (which is what you use to calculate your tax). The form also shows you how much tax you have paid during the year. Form 1040 is the tax return that you use to calculate your correct tax for the year. You start with the gross income amount from the W-2, and the first thing you do is add in any income that you didn't get a W-2 for (such as interest or investment income) and subtract any deductions that you might have that are not taxable, but were not paid through your paycheck (such as moving expenses, student loan interest, tuition, etc.) The result is called your adjusted gross income. Next, you take off the deductions not covered in the above section (property tax, home mortgage interest, charitable giving, etc.). You can either take the standard deduction ($6,300 if you are single), or if you have more deductions in this category than that, you can itemize your deductions and declare the correct amount. After that, you subtract more for exemptions. You can claim yourself as an exemption unless you are considered a dependent of someone else and they are claiming you as a dependent. If you claim yourself, you take off another $4,000 from your income. What you are left with is your taxable income for the year. This is the amount you would use to calculate your tax based on the bracket table you found.

CD1b+ dendritic cells were expanded by TLR-mediated upregulation of granulocyte-macrophage colony-stimulating factor (GM-CSF) and its receptor, promoted T cell activation and secreted proinflammatory cytokines. Whereas DC-SIGN+ macrophages were detected in lesions and after TLR activation in all leprosy patients, CD1b+ dendritic cells were not detected in lesions or after TLR activation of peripheral monocytes in individuals with the progressive lepromatous form, except during reversal reactions in which bacilli were cleared by T helper type 1 (TH1) responses. In tuberculoid lepromatous lesions, DC-SIGN+ cells were positive for macrophage markers, but negative for dendritic cell markers. Thus, TLR-induced differentiation of monocytes into either macrophages or dendritic cells seems to crucially influence effective host defenses in human infectious disease.", "title": "TLR activation triggers the rapid differentiation of monocytes into macrophages and dendritic cells" } ]

We defined vulnerability of intracoronary plaques according to the presence of positive remodeling (remodeling index >1.05) and/or low CT attenuation (<35 HU). The circulating CD14++CD16+monocytes more frequently expressed TLR-4 than CD14++CD16-and CD14+CD16+monocytes (P<0.001).

This rapid innate-like immune response allows Ag-experienced T cells to alert other immune cell types to pathogenic intruders. In this study, we show that murine CD8(+) T cells can sense TLR2 and TLR7 ligands, resulting in rapid production of IFN-γ but not of TNF-α and IL-2. Importantly, Ag-experienced T cells activated by TLR ligands produce sufficient IFN-γ to augment the activation of macrophages. In contrast to Ag-specific reactivation, TLR-dependent production of IFN-γ by CD8(+) T cells relies exclusively on newly synthesized transcripts without inducing mRNA stability. Furthermore, transcription of IFN-γ upon TLR triggering depends on the activation of PI3K and serine-threonine kinase Akt, and protein synthesis relies on the activation of the mechanistic target of rapamycin. We next investigated which energy source drives the TLR-induced production of IFN-γ. Although Ag-specific cytokine production requires a glycolytic switch for optimal cytokine release, glucose availability does not alter the rate of IFN-γ production upon TLR-mediated activation. Rather, mitochondrial respiration provides sufficient energy for TLR-induced IFN-γ production. To our knowledge, this is the first report describing that TLR-mediated bystander activation elicits a helper phenotype of CD8(+) T cells. It induces a short boost of IFN-γ production that leads to a significant but limited activation of Ag-experienced CD8(+) T cells.

GS-9620 was previously shown to induce prolonged suppression of serum viral DNA and antigens in the woodchuck and chimpanzee models of CHB. Herein, we investigated the molecular mechanisms that contribute to the antiviral response to GS-9620 using in vitro models of hepatitis B virus (HBV) infection. METHODS Cryopreserved primary human hepatocytes (PHH) and differentiated HepaRG (dHepaRG) cells were infected with HBV and treated with GS-9620, conditioned media from human peripheral blood mononuclear cells treated with GS-9620 (GS-9620 conditioned media [GS-9620-CM]), or other innate immune stimuli. The antiviral and transcriptional response to these agents was determined. RESULTS GS-9620 had no antiviral activity in HBV-infected PHH, consistent with low level TLR7 mRNA expression in human hepatocytes. In contrast, GS-9620-CM induced prolonged reduction of HBV DNA, RNA, and antigen levels in PHH and dHepaRG cells via a type I interferon (IFN)-dependent mechanism. GS-9620-CM did not reduce covalently closed circular DNA (cccDNA) levels in either cell type. Transcriptional profiling demonstrated that GS-9620-CM strongly induced various HBV restriction factors - although not APOBEC3A or the Smc5/6 complex - and indicated that established HBV infection does not modulate innate immune sensing or signaling in cryopreserved PHH. GS-9620-CM also induced expression of immunoproteasome subunits and enhanced presentation of an immunodominant viral peptide in HBV-infected PHH. CONCLUSIONS Type I IFN induced by GS-9620 durably suppressed HBV in human hepatocytes without reducing cccDNA levels. Moreover, HBV antigen presentation was enhanced, suggesting additional components of the TLR7-induced immune response played a role in the antiviral response to GS-9620 in animal models of CHB. LAY SUMMARY GS-9620 is a drug currently being tested in clinical trials for the treatment of chronic hepatitis B virus (HBV) infection. GS-9620 has previously been shown to suppress HBV in various animal models, but the underlying antiviral mechanisms were not completely understood. In this study, we determined that GS-9620 does not directly activate antiviral pathways in human liver cells, but can induce prolonged suppression of HBV via induction of an antiviral cytokine called interferon. However, interferon did not destroy the HBV genome, suggesting that other parts of the immune response (e.g. activation of immune cells that kill infected cells) also play an important role in the antiviral response to GS-9620.", "title": "Toll-like receptor 7 agonist GS-9620 induces prolonged inhibition of HBV via a type I interferon-dependent mechanism." }, { "docid": "27602752", "text": "Encephalitis and dementia associated with acquired immunodeficiency syndrome (AIDS) are characterized by leukocyte infiltration into the CNS, microglia activation, aberrant chemokine expression, blood-brain barrier (BBB) disruption, and eventual loss of neurons. Little is known about whether human immunodeficiency virus 1 (HIV-1) infection of leukocytes affects their ability to transmigrate in response to chemokines and to alter BBB integrity. We now demonstrate that HIV infection of human leukocytes results in their increased transmigration across our tissue culture model of the human BBB in response to the chemokine CCL2, as well as in disruption of the BBB, as evidenced by enhanced permeability, reduction of tight junction proteins, and expression of matrix metalloproteinases (MMP)-2 and MMP-9. HIV-infected cells added to our model did not transmigrate in the absence of CCL2, nor did this condition alter BBB integrity. The chemokines CXCL10/interferon-gamma-inducible protein of 10 kDa, CCL3/macrophage inflammatory protein-1alpha, or CCL5/RANTES (regulated on activation normal T-cell expressed and secreted) did not enhance HIV-infected leukocyte transmigration or BBB permeability. The increased capacity of HIV-infected leukocytes to transmigrate in response to CCL2 correlated with their increased expression of CCR2, the chemokine receptor for CCL2.

Here, we examined PAR(2) activation in the rat knee joint. EXPERIMENTAL APPROACH PAR(2) in rat knee joint dorsal root ganglia (DRG) cells at L3-L5, retrogradely labelled with Fluoro-gold (FG) were demonstrated immunohistochemically. Electrophysiological recordings from knee joint nerve fibres in urethane anaesthetized Wistar rats assessed the effects of stimulating joint PAR(2) with its activating peptide, 2-furoyl-LIGRLO-NH(2) (1-100 nmol·100 μL(-1) , via close intra-arterial injection). Fibre firing rate was recorded during joint rotations before and 15 min after administration of PAR(2) activating peptide or control peptide. Leukocyte kinetics in the synovial vasculature upon PAR(2) activation were followed by intravital microscopy for 60 min after perfusion of 2-furoyl-LIGRLO-NH(2) or control peptide. Roles for transient receptor potential vanilloid-1 (TRPV1) or neurokinin-1 (NK(1) ) receptors in the PAR(2) responses were assessed using the selective antagonists, SB366791 and RP67580 respectively. KEY RESULTS PAR(2) were expressed in 59 ± 5% of FG-positive DRG cells; 100 nmol 2-furoyl-LIGRLO-NH(2) increased joint fibre firing rate during normal and noxious rotation, maximal at 3 min (normal; 110 ± 43%, noxious; 90 ± 31%). 2-Furoyl-LIGRLO-NH(2) also significantly increased leukocyte rolling and adhesion over 60 min.

However, few mutant epitopes have been described because their discovery required the laborious screening of patient tumour-infiltrating lymphocytes for their ability to recognize antigen libraries constructed following tumour exome sequencing. We sought to simplify the discovery of immunogenic mutant peptides by characterizing their general properties. We developed an approach that combines whole-exome and transcriptome sequencing analysis with mass spectrometry to identify neo-epitopes in two widely used murine tumour models. Of the >1,300 amino acid changes identified, ∼13% were predicted to bind MHCI, a small fraction of which were confirmed by mass spectrometry. The peptides were then structurally modelled bound to MHCI. Mutations that were solvent-exposed and therefore accessible to T-cell antigen receptors were predicted to be immunogenic. Vaccination of mice confirmed the approach, with each predicted immunogenic peptide yielding therapeutically active T-cell responses. The predictions also enabled the generation of peptide–MHCI dextramers that could be used to monitor the kinetics and distribution of the anti-tumour T-cell response before and after vaccination.

[ { "docid": "278630", "text": "Firstly what are you trading that you could lose more than you put in? If you are simply trading stocks you will not lose more than you put in, unless you are trading on margin. A limit order is basically that, a limit on the maximum price you want your buy order bought at or the minimum price you want your sell order sold at. If you can't be glued to the screen all day when you place a limit order, and the market moves the opposite way, you may miss out on your order being executed. Even if you can be in front of the screen all day, you then have to decide if you want to chase the market of miss out on your purchase or sale. For example, if a stock is trading at $10.10 and you put a limit buy order to buy 1000 shares at or below $10.00 and the price keeps moving up to $10.20, then $10.30 and then $10.50, until it closes the day at $11.00. You then have the choice during the day to miss out on buying the shares or to increase your limit order in order to buy at a higher price. Sometime if the stock is not very liquid, i.e. it does not trade very often and has low volume, the price may hit $10.00 and you may only have part of your order executed, say 500 out of your 1000 shares were bought. This may mean that you may have to increase the price of your remaining order or be happy with only buying 500 shares instead of 1000. The same can happen when you are selling (but in reverse obviously). With market order, however, you are placing a buy order to buy at the next bid price in the depth or a sell order to sell at the next offer price in the depth. See the market depth table below: Note that this price depth table is taken before market open so it seems that the stock is somewhat illiquid with a large gap between the first and second prices in the buyers (bid) prices. When the market opened this gap is closed, as WBC is a major Australian bank and is quite liquid. (the table is for demonstration purposes only). If we pretend that the market was currently open and saw the current market depth for WBC as above, you could decide to place a limit sell order to sell 1000 shares at say $29.91. You would sell 100 shares straight away but your remaining 900 sell order will remain at the top of the Sellers list. If other Buyers come in at $29.91 you may get your whole sale completed, however, if no other Buyers place orders above $29.80 and other Sellers come into the market with sell orders below $29.91, your remaining order may never be executed. If instead you placed a market sell order you would immediately sell 100 shares at $29.91 and the remaining 900 shares at $29.80. (so you would be $99 or just over 0.3% worse off than if you were able to sell the full 1000 shares at $29.91). The question is how low would you have had to lower your limit order price if the price for WBC kept on falling and you had to sell that day? There are risks with whichever type of order you use. You need to determine what the purpose of your order is. Is it to get in or out of the market as soon as possible with the possibility of giving a little bit back to the market? Or is it to get the price you want no matter how long it takes you? That is you are willing to miss out on buying the shares (can miss out on a good buy if the price keeps rising for weeks or months or even years) or you are willing to miss out on selling them right now and can wait for the price to come back up to the price you were willing to sell at (where you may miss out on selling the shares at a good price and they keep on falling and you give back all your profits and more). Just before the onset of the GFC I sold some shares (which I had bought a few years earlier at $3.40) through a market order for $5.96. It had traded just above $6 a few days earlier, but if instead of a market order I had placed a limit order to sell at $6.00 or more I would have missed out on the sale. The price never went back up to $6 or above, and the following week it started dropping very quickly. It is now trading at about $1.30 and has never gone back above $2.00 (5.5 years later).

In simplest terms, the 'price' of a stock is the price at which the most recent trade occurred. ie: if the price of IBM is $100/share, that means the last time someone bought IBM stock, they paid $100. Above and below the 'spot price', are dozens/hundreds/thousands of buyers and sellers who have placed orders that no one is yet willing to match. ie: if IBM's spot price is at $100, there could still be 10,000 people willing to sell for $101 (called the 'ask' price, for the lowest price someone is currently willing to sell at), and 15,000 willing to buy for $99 (called the 'bid' price, for the highest price someone is currently willing to buy for). Until someone is willing to buy for $101, then no one will be able to sell at $101. Until someone is willing to sell for $99, no one will be able to buy for $99. Typically orders are placed in the market at a particular limit. Meaning that those orders to buy at $99/sell at $101 are already in the 'system', and will be matched immediately as soon as someone is willing to meet the price on the other side. Now consider general market economics: high demand drives up price, and high supply drives down price. If the details above for IBM were yesterday, and today some news came out that IBM was laying off employees, imagine that another 10,000 people who held shares wanted to sell. Now there would be 20,000 sellers and only 15,000 buyers. If those new sellers were aggressive about wanting to sell, they would have to drop their price to $99, to match the highest buyers in the market. Put together, this means that as more sellers enter the market, supply of shares increases, driving down price. Conversely, as more buyers enter the market, demand for shares increases, driving up share price. As a result of the above, you can say that (all else being equal) if price for a stock goes up, there were more buyers that day, and if price goes down, there were more sellers that day. On the face of it, that is not necessarily true, because you could have the same number of buyers and sellers, one side could have simply decreased/increased their acceptable price to match the other side.", "title": "" }, { "docid": "494727", "text": "\"Re: A trader when buying needs to buy at the ask price and when selling needs to sell at the bid price. So how can a trade happen 'in between' the bid and ask? Saying the trade can happen \"\"in between\"\" the bid & ask is simplistic. There is a time dimension to the market. It's more accurate to say that an order can be placed \"\"in between\"\" the current best bid & ask (observed at time T=0), thus establishing a new level for one or the other of those quoted prices (observed at time T>0). If you enter a market order to buy (or sell), then yes, you'll generally be accepting the current best ask (or best bid) with your order, because that's what a market order says to do: Accept the current best market price being offered for your kind of transaction. Of course, prices may move much faster than your observation of the price and the time it takes to process your order – you're far from being the only participant. Market orders aside, you are free to name your own price above or below the current best bid & ask, respectively. ... then one could say that you are placing an order \"\"in between\"\" the bid and ask at the time your order is placed. However – and this is key – you are also moving one or the other of those quoted prices in the process of placing your above-bid buy order or your below-ask sell order. Then, only if somebody else in the market chooses to accept your new ask (or bid) does your intended transaction take place. And that transaction takes place at the new ask (or bid) price, not the old one that was current when you entered your order. Read more about bid & ask prices at this other question: (p.s. FWIW, I don't necessarily agree with the assertion from the article you quoted, i.e.: \"\"By looking for trades that take place in between the bid and ask, you can tell when a strong trend is about to come to an end.\"\" I would say: Maybe, perhaps, but maybe not.)\"", "title": "" }, { "docid": "151987", "text": "I don't think user4358's explanation is correct. A trailing LIT Sell Order adjusts downwards, i.e. if you place the order with an Aux price (in TWS it's trigger price) of 105.00 and a trailing amount of 6.00 then, assuming the ask is 100.00, TWS will add the trailing amount to the ask price and if it's less than the trigger price it will adjust. So in my example, if the market (ask) goes straight up to 105.00, nothing will be adjusted, the trigger is touched and the limit order will be placed (see below). If on the the other hand the market goes down to 99.00 then trlng amt + ask is 105.00, if it goes further down to 98.00 then the trigger price will be adjusted to 104.00 (because it's less than the current trigger), and so on. For the LIT part you have either an absolute limit price you can enter, or you have an offset limit which will be subtracted from the trigger price, in which case it is adjusted as well. So back to my example, the trigger is now 104.00 and the limit offset is say 1.00, so my limit order would be placed at 103.00 if the ask ever touches 104.00, and that in turn is only visible if the bid touches 103.00 (because it's limit-if-touched). For a buy just use the same explanation with some swapped roles, the trigger price adjust upwards when the trailing amount plus bid is larger than the current trigger, and the limit offset will be added to the trigger price. Edit Also quite succinct and worth having a look at: http://www.interactivebrokers.com/en/trading/orders/trailingLimitTouched.php Guesswork, highly subjective As for why this might be good, well, you have to believe in momentum strategies, i.e. a market that goes down, will continue to go down, if you believe that and you believe in mean reversion as well, then a trailing limit order can assist you in not buying/selling impulsively, but closer to the mean. I've never used it that way though. What I have done, even just now to get the explanation right, is to place trailing buy and sell orders simultaneously. You will find that you can just go in with coarse estimates and because the adjustments will go towards each other, you will end up with a narrowing band of trigger prices (as opposed to trailing stop orders which will give you a widening band of trigger prices). If you believe in overshooting and equilibria then this can be one easy way to profit from it.

Whilst an online broker usually doesn't provide advice (unless you ask for it at a specified fee), you place your orders online through the brokers website or trading platform and the commissions are usually much lower. The best thing to do when starting off is to go to your country's stock exchange, for example, The ASX in Sydney Australia, and they should have a list of available brokers. Some of the online brokers may have a practice or simulation account you can practice on, and they usually provide good educational material to help you get started. If you went with an online broker and wanted to buy Facebook on the secondary market (that is on the stock exchange after the IPO closes), you would log onto your brokers website or platform and go to the orders section. You would place a new order to buy say 100 Facebook shares at a certain price. You can use a market order, meaning the order will be immediately executed at the current market price and you will own the shares, or a limit price order where you select a price below the current market price and wait for the price to come down and hit your limit price before your order is executed and you get your shares. There are other types of orders available with different brokers which you will learn about when you log onto their website. You also need to be careful that you have the funds available to pay for the share at settlement, which is 3 business days after your order was executed.

For any given tick, however, there are many bid-ask prices because securities can trade on multiple exchanges and between many agents on a single exchange. This is true for both types of exchanges that Chris mentioned in his answer. Chris' answer is pretty thorough in explaining how the two types of exchanges work, so I'll just add some minor details. In exchanges like NASDAQ, there are multiple market makers for most relatively liquid securities, which theoretically introduces competition between them and therefore lowers the bid-ask spreads that traders face. Although this results in the market makers earning less compensation for their risk, they hope to make up the difference by making the market for highly liquid securities. This could also result in your order filling, in pieces, at several different prices if your brokerage firm fills it through multiple market makers. Of course, if you place your order on an exchange where an electronic system fills it (the other type of exchange that Chris mentioned), this could happen anyway. In short, if you place a market order for 1000 shares, it could be filled at several different prices, depending on volume, multiple bid-ask prices, etc. If you place a sizable order, your broker may fill it in pieces regardless to prevent you from moving the market. This is rarely a problem for small-time investors trading securities with high volumes, but for investors with higher capital like institutional investors, mutual funds, etc. who place large orders relative to the average volume, this could conceivably be a burden, both in the price difference across time as the order is placed and the increased bookkeeping it demands. This is tangentially related, so I'll add it anyway. In cases like the one described above, all-or-none (AON) orders are one solution; these are orders that instruct the broker to only execute the order if it can be filled in a single transaction. Most brokers offer these, but there are some caveats that apply to them specifically. (I haven't been able to find some of this information, so some of this is from memory). All-or-none orders are only an option if the order is for more than a certain numbers of shares. I think the minimum size is 300 or 400 shares. Your order won't be placed until your broker places all other orders ahead of it that don't have special conditions attached to them. I believe all-or-none orders are day orders, which means that if there wasn't enough supply to fill the order during the day, the order is cancelled at market close. AON orders only apply to limit orders.

But, think of the bid and ask prices you see as \"\"tip of the iceberg\"\" prices. That is: The \"\"Bid: 13.20 x200\"\" is an indication that there are potential buyers bidding $13.20 for up to 200 shares. Their bids are the highest currently bid; and there are others in line behind with lower bid prices. So the \"\"bid\"\" you're seeing is actually the best bid price at that moment. If you entered a \"\"market\"\" order to sell more than 200 shares, part of your order would likely be filled at a lower price. The \"\"Ask: 13.27 x1,000\"\" is an indication that there are potential sellers asking $13.27 for up to 1000 shares. Their ask prices are the lowest currently asked; and there are others in line behind with higher ask prices. So the \"\"ask\"\" you're seeing is the best asking price at that moment.

A transaction takes place when either a potential buyer is willing to pay the asking price, or a potential seller is willing to accept the bid price, or else they meet in the middle if both buyers and sellers change their orders. Note: There are primarily two kinds of stock exchanges. The one I just described is a typical order-driven matched bargain market, and perhaps the kind you're referring to. The other kind is a quote-driven over-the-counter market where there is a market-maker, as JohnFx already mentioned. In those cases, the spread between the bid & ask goes to the market maker as compensation for making a market in a stock. For a liquid stock that is easy for the market maker to turn around and buy/sell to somebody else, the spread is small (narrow). For illiquid stocks that are harder to deal in, the spread is larger (wide) to compensate the market-maker having to potentially carry the stock in inventory for some period of time, during which there's a risk to him if it moves in the wrong direction. Finally ... if you wanted to buy 1000 shares, you could enter a market order, in which case as described above you'll pay $13.27. If you wanted to buy your shares at no more than $13.22 instead, i.e. the so-called \"\"current\"\" price, then you would enter a limit order for 1000 shares at $13.22. And more to the point, your order would become the new highest-bid price (until somebody else accepts your bid for their shares.)

As sdg said, a put option is basically an insurance policy on the stock; you pay a certain price for the contract itself, which locks in a sale price up to a particular future date. If the stock depreciates significantly, you exercise the option and get the contract price; otherwise you let the contract expire and keep the stock. Long-term, these are bad bets as each expired contract will offset earnings, but if you foresee a near-term steep drop in the stock price but aren't quite sure, a put option is good peace of mind. A sell stop order is generally cheaper, but less reliable. You set a trigger price, say a loss of 10% of the stock's current value. If that threshold is reached, the stop order becomes a sell order and the broker will sell the stock on the market, take his commission (or a fixed price depending on your broker) and you get the rest. However, there has to be a buyer willing to buy at that price at the moment the trigger fires; if a stock has lost 10% rapidly, it's probably on the way down hard, and the order might not complete until you realize a 12% loss, or a 15%, or even 20%. A sell stop limit (a combination stop order and limit order) allows you to say that you want to sell if the stock drops to $X, but not sell if it drops below $X-Y. This allows you to limit realized losses by determining a band within which it should be sold, and not to sell above or below that price. These are cheaper because you only pay for the order if it is executed successfully; if you never need it, it's free (or very cheap; some brokers will charge a token service fee to maintain a stop or stop limit). However, if the price drops very quickly or you specify too narrow a band, the stock can drop through that band too quickly to execute the sell order and you end up with a severely depreciated stock and an unexercised order. This can happen if the company whose stock you own buys another company; VERY quickly, both stocks will adjust, the buying company will often plummet inside a few seconds after news of the merger is announced, based on the steep drop in working capital and/or the infusion of a large amount of new stock in the buying company to cover the equity of the purchased company. You end up with devalued stock and a worthless option (but one company buying another is not usually reason to sell; if the purchase is a good idea, their stock will recover). Another option which may be useful to you is a swaption; this basically amounts to buying a put option on one financial instrument and a call on another, rolled into one option contract specifying a swap. This allows you to pick something you think would rise if your stock fell and exchange your stock for it at your option. For example, say the stock on which you buy this swaption is an airline stock, and you contract the option to swap for oil. If oil surges, the airline's stock will tank sharply, and you win both ways (avoiding loss and realizing a gain). You'd also win if either half of this option realized a gain over the option price; oil could surge or the airline could tank and you could win. You could even do this \"\"naked\"\" since its your option; if the airline's stock tanks, you buy it at the crashed price to exercise the option and then do so.

Simple algorithms attempt to get a price close to the time-weighted average price (TWAP) or volume-weighted average price (VWAP) and would buy a smaller amount every N minutes. Despite splitting the order into smaller pieces the price usually moves against the trader for many reasons. There are many models to estimate the market impact of an order before executing it and many brokers have their own model, for example Deutsche Bank. There is considerable research on \"\"market impact\"\" if you are interested. I understand the general principal that when significant buy orders comes in relative to the sell orders price goes up and when a significant sell order comes in relative to buy orders it goes down. I consider this statement wrong or at least misleading. First, stocks can jump in price without or with very little volume. Consider a company that releases a negative earnings surprise over night. On the next day the stock may open 20% lower without any orders having matched for any price in between. The price moved because the perception of the stocks value changed, not because of buy or sell pressure. Second, buy and sell pressure have an effect on the price because of the underlying reason, and not necessarily/only because of the mechanics of the market. Assume you were prepared to sell HyperNanoTech stock, but suddenly there's a lot of buzz and your colleagues are talking about buying it. Would you still sell it for the same price? I wouldn't. I would try to find out how much they are prepared to buy it for. In other words, buy pressure can be the consequence of successful marketing of the stock and the marketing buzz is what changes the price.\"", "title": "" }, { "docid": "285126", "text": "\"I may be underestimating your knowledge of how exchanges work; if so, I apologize. If not, then I believe the answer is relatively straightforward. Lets say price of a stock at time t1 is 15$ . There are many types of price that an exchange reports to the public (as discussed below); let's say that you're referring to the most recent trade price. That is, the last time a trade executed between a willing buyer and a willing seller was at $15.00. Lets say a significant buy order of 1M shares came in to the market. Here I believe might be a misunderstanding on your part. I think you're assuming that the buy order must necessarily be requesting a price of $15.00 because that was the last published price at time t1. In fact, orders can request any price they want. It's totally okay for someone to request to buy at $10.00. Presumably nobody will want to sell to him, but it's still a perfectly valid buy order. But let's continue under the assumptions that at t1: This makes the bid $14.99 and the ask $15.00. (NYSE also publishes these prices.) There aren't enough people selling that stock. It's quite rare (in major US equities) for anyone to place a buy order that exceeds the total available shares listed for sale at all prices. What I think you mean is that 1M is larger than the amount of currently-listed sell requests at the ask of $15.00. So say of the 1M only 100,000 had a matching sell order and others are waiting. So this means that there were exactly 100,000 shares waiting to be sold at the ask of $15.00, and that all other sellers currently in the market told NYSE they were only willing to sell for a price of $15.01 or higher. If there had been more shares available at $15.00, then NYSE would have matched them. This would be a trigger to the automated system to start increasing the price. Here is another point of misunderstanding, I think. NYSE's automated system does not invent a new, higher price to publish at this point. Instead it simply reports the last trade price (still $15.00), and now that all of the willing sellers at $15.00 have been matched, NYSE also publishes the new ask price of $15.01. It's not that NYSE has decided $15.01 is the new price for the stock; it's that $15.01 is now the lowest price at which anyone (known to NYSE) is willing to sell. If nobody happened to be interested in selling at $15.01 at t1, but there were people interested in selling at $15.02, then the new published ask would be $15.02 instead of $15.01 -- not because NYSE decided it, but just because those happened to be the facts at the time. Similarly, the new bid is most likely now $15.00, assuming the person who placed the order for 1M shares did not cancel the remaining unmatched 900,000 shares of his/her order. That is, $15.00 is now the highest price at which anyone (known to NYSE) is willing to buy. How much time does the automated system wait to increment the price, the frequency of the price change and by what percentage to increment etc. So I think the answer to all these questions is that the automated system does none of these things. It merely publishes information about (a) the last trade price, (b) the price that is currently the lowest price at which anyone has expressed a willingness to sell, and (c) the price that is currently the highest price at which anyone has expressed a willingness to buy. ::edit:: Oh, I forgot to answer your primary question. Can we estimate the impact of a large buy order on the share price? Not only can we estimate the impact, but we can know it explicitly. Because the exchange publishes information on all the orders it knows about, anyone tracking that information can deduce that (in this example) there were exactly 100,000 shares waiting to be purchased at $15.00. So if a \"\"large buy order\"\" of 1M shares comes in at $15.00, then we know that all of the people waiting to sell at $15.00 will be matched, and the new lowest ask price will be $15.01 (or whatever was the next lowest sell price that the exchange had previously published).\"", "title": "" }, { "docid": "353396", "text": "\"Say we have stock XYZ that costs $50 this second.

For example if you have a stop loss (conditional order) set at say 10% below your buy price, you might want to use a market order to make sure your order gets executed if the price drops 10% and your stop loss gets triggered, making sure that you get out of the stock instead of being stuck with a limit order 10% below your buy price whilst the stock keeps falling further.", "title": "" }, { "docid": "339419", "text": "Sounds like an illiquid option, if there are actually some bidders, market makers, then sell the option at market price (market sell order).

Advantages of Shareholder over Director in new Company
[ { "docid": "82119", "text": "I know the general principles of acting as a director in a company, and am familiar with the rights of shareholders. In the last ten years or so, I believe Australia has introduced legislation that strongly punishes those directors who do not act in a professional or prudent manner. While I will of course attempt to fulfill the duties required - I am new to conducting business at this level, and am concerned about mistakenly breaching some unknown rule/law and being subject to repercussions that I just don't know about. As you have already stated, the key to being director in a company is the additional responsibility. Legally you can be held in breach. At the same time you will be able to influence your decision much better if you a director and thus safeguard your interest. If you are only a shareholder, you cannot be held responsible for decision by company, individual malpractice may still be applicable, but this is less of a risk. However over a period of time, the board can take certain decision that may marginalize your holding in the company.", "title": "" }, { "docid": "80742", "text": "I don't know Australian law, but I will give my US perspective here. The custom in the US is for officers and directors to be indemnified by the corporation, and that LLCs have an even broader power to indemnify (even to remove the duty of loyalty!). Moreover, directors will typically be able to purchase D&O insurance to protect them from loss in the event of liability. For US corporations (not LLCs), the duty of care (prudence) requires that directors behave responsibly in weighing major decisions, and consult experts and specialists before coming to rash decisions. It usually becomes a court case in the context of a large public company in the midst of an acquisition event. The only people with standing (in the US) are shareholders. If all the other shareholders are directors, then it may be hard for them to blame you. Additionally, if you are concerned about the propriety of your actions, there may be sources to rely on. First, discussion with your fellow directors can be a helpful guide (though will not usually immunize you from any accusation of wrongdoing), and disclosure tends to cure almost any accusation of breaching the duty of loyalty. Second, boards often secure the advice of legal counsel, and sometimes bring on lawyers as members or will outright hire counsel for the board. Third, there may be services that will provide you with generic advice (e.g. UK Companies House and US-based IOD), which might set you at ease a little bit. I don't know the details of Australian law, as I say. But my sense of common law countries is that, like the US, they are primarily concerned about negligence (incompetently or imprudently neglecting to understand the business and make informed decisions), disloyalty (fraudulently engaging in self-interested transactions that either hurt the company or should have been offered to the company), and recklessness (not bothering to seek out information). As long as you are active, informed, engaged, and not engaging in secret deals outside the company (especially deals where either side is competing with the company), then that would be more than sufficient under the US standard. If you are concerned about liability, then inquire into indemnifications by the company (in the US, the company can usually pay all legal costs of directors), insurance, and legal counsel. I imagine your business partners are no more savvy than you are. My impression is you are overreacting to relatively rare and exotic expression of corporate law (at least in the US).

[ { "docid": "71614", "text": "\"&gt;As a legal matter, shareholders who purchase shares of stock in a corporation own nothing more than that—shares of stock. Similarly, bondholders own only bonds, and executives with employment contracts own their contracts. None of these types of ownership give shareholders, bondholders or executives the right to control the firm. The right to control the firm’s assets and actions rests in the hands of its board of directors, and only when they act as a body and follow proper board procedures. All this says is \"\"decisions are made by the board.\"\" This is not news, and it doesn't mean that shareholders do not own the company. Shareholders elect the board, by the way. &gt;An important consequence of this governance structure is that shareholders not only have no legal right to control the firm, they also have no legal right to help themselves to the corporation’s assets. Well, that's wrong. &gt;In fact, the only time shareholders receive any funds directly from the corporation’s coffers is when they receive a dividend or the corporation repurchases their shares. Or, you know, in the case of bankruptcy. &gt;This only happens when the directors vote to declare a dividend or a corporate repurchase. The same directors who were appointed by shareholders. &gt;At law, a principal has a right to control her agent. But shareholders can’t exercise direct control over corporate directors.

In effect, bondholders own the right to access cash flow but have sold a call to shareholders, while shareholders own the right to access the cash flow but have sold a put to bondholders. Neither shareholders nor bondholders can claim an exclusive right to “own” the company’s cash flow, much less the company. This is a made up explanation that doesn't mean anything. The real options model of corporate assets is that corporate debt is a risk-free bond with a short put option and equity is a call option.

But many profitable companies do just that, and those that don't could, some day. Profits & dividends is where your analogy falls apart. But let's take it further. Consider: If baseball cards could somehow yield a regular stream of income just for owning them, then there might be yet another group of people, call them the Daves. These Daves I know are the kind of people that would like to own baseball cards over the long term just for their income-producing capability. Daves would seek out the cards with the best chance of producing and growing a reliable income stream. They wouldn't necessarily care about being able to flip a card at an inflated price to a Bob, but they might take advantage of inflated prices once in a while. Heck, even some of the Steves would enjoy this income while they waited for the eventual capital gain made by selling to a Bob at a higher price. Plus, the Steves could also sell their cards to Daves, not just Bobs. Daves would be willing to pay more for a card based on its income stream: how reliable it is, how high it is, how fast it grows, and where it is relative to market interest rates. A card with a good income stream might even have more value to a Dave than to a Bob, because a Dave doesn't care as much about the popularity of the player. Addendum regarding your comment: I suppose I'm still struggling with the best way to present my question. I understand that companies differ in this aspect in that they produce value. But if stockholders cannot simply claim a percentage of a company's value equal to their share, then the fact that companies produce value seems irrelevant to the \"\"Bobs\"\". You're right – stockholders can't simply claim their percentage of a company's assets. Rather, shareholders vote in a board of directors. The board of directors can decide whether or not to issue dividends or buy back shares, each of which puts money back in your pocket. A board could even decide to dissolve the company and distribute the net assets (after paying debts and dissolution costs) to the shareholders – but this is seldom done because there's often more profit in remaining a going concern. I think perhaps what you are getting hung up on is the idea that a small shareholder can't command the company to give net assets in exchange for shares. Instead, generally speaking, a company runs somewhat like a democracy – but it's each share that gets a vote, not each shareholder. Since you can't redeem your shares back to the company on demand, there exists a secondary market – the stock market – where somebody else is willing to take over your investment based on what they perceive the value of your shares to be – and that market value is often different from the underlying \"\"book value\"\" per share.\"", "title": "" }, { "docid": "210889", "text": "Another person, not a shareholder or director, will be treated as when a bank loans you money.

The directors (and thus the executives and employees) have a legal responsibility to manage the company in a way which is beneficial for the shareholders, since the shareholders are the ultimate owner of the company. A mutual insurance company is similar, except that the people holding policies are also the shareholders. That is, the policyholders are the ultimate owners of the company, and there generally aren't separate shareholders who are just “investing” in the company. These policyholder-shareholders elect the board of directors, who select the senior executive(s), who manage the people who run the actual company.

Also, insurance companies are generally pretty heavily regulated in terms of what they can do, because governments really like them to remain solvent. It may be comforting to know that in a mutual insurance company the higher-ups are explicitly supposed to be working in your best interest, though, rather than in the interest of some random investors.

Policyholders, despite their status as owners, have no meaningful oversight of how mutual companies spend their money — whether to lower rates, pay dividends, or fund executive salaries and perks — and few avenues to challenge such decisions. Another reason that one might not like the conversion is the specific details of how the current investor-shareholders are being paid back for their investment in the process of the conversion to mutual ownership, and what that might do to the funds on hand that are supposed to be there to keep the firm solvent for the policyholders. From another Boston Globe article on the conversion of SBLI to a mutual company, “Insurer SBLI wants to get banks out of its business,” professor Robert Wright is cautiously optimistic but wants to ensure the prior shareholders aren't overpaid: Robert Wright, a professor in South Dakota who has studied insurance companies and owns an SBLI policy, said he would prefer the insurer to be a mutual company that doesn’t have to worry about the short-term needs of shareholders. But he wants to ensure that SBLI doesn’t overpay the banks for their shares. “It’s fine, as long as it’s a fair price,” he said. That article also gives SBLI's president's statement as to why they think it's a good thing for policyholders: If the banks remained shareholders, they would be likely to demand a greater share of the profits and eat into the dividends the insurance company currently pays to the 536,000 policyholders, about half of whom live in Massachusetts, said Jim Morgan, president of Woburn-based SBLI. “We’re trying to protect the policyholders from having the dividends diluted,” Morgan said. I'm not sure there's an obvious pros/cons list for either way, but I'd think that I'd prefer the mutual approach, just on the principle that the policyholders “ought” to be the owners, because the directors (and thus the executives and employees) are then legally required to manage the company in the best interest of the policyholders. I did cast a Yes vote in my proxy on whether SBLI ought to become a mutual company (I'm a SBLI term-life policyholder.)

The company can pay money into a pension of the company director (that's You in your role as company director) up to £40,000 or so a year; that money is deducted from its profits again. The company pays 20% tax on its remaining profits. Then the company can pay You, in your role as company director, a dividend, usually twice a year. Each of these payments has to be written down and given to HMRC properly. Best by far to use an accountant to do all the paper work for you and advice you what to do. You can lose a lot of money by just not getting the paperwork right, by filing late etc., which the accountant will get right. The accountant will also tell you what are the optimal amounts for salary and dividend (best is a small salary, about £10,000 a year, dividend of about £30,000 a year, pension as much as the company can afford, which is then all tax free to you).

On the other hand, if you are saying that the people who get paid to be knowledgeable about that stuff should just go make the decisions without troubling you with the details, then choose the option to go with their recommendations, which are always clearly indicated on the voting form.

What do \"\"for,\"\" \"\"against,\"\" \"\"abstain\"\"and \"\"withhold\"\" mean on the proxy card or voter instruction form? Depending on what you are voting on, the proxy card or voting instruction form gives you a choice of voting \"\"for,\"\" \"\"against,\"\" or \"\"abstain,\"\" or \"\"for\"\" or \"\"withhold.\"\" Here is an explanation of the differences: Election of directors: Generally, company bylaws or other corporate documents establish how directors are elected. There are two main types of ways to elect directors: plurality vote and majority vote. A \"\"plurality vote\"\" means that the winning candidate only needs to get more votes than a competing candidate. If a director runs unopposed, he or she only needs one vote to be elected, so an \"\"against\"\" vote is meaningless. Because of this, shareholders have the option to express dissatisfaction with a candidate by indicating that they wish to \"\"withhold\"\" authority to vote their shares in favor of the candidate. A substantial number of \"\"withhold\"\" votes will not prevent a candidate from getting elected, but it can sometimes influence future decisions by the board of directors concerning director nominees. A \"\"majority vote\"\" means that directors are elected only if they receive a majority of the shares voting or present at the meeting. In this case, you have the choice of voting \"\"for\"\" each nominee, \"\"against\"\" each nominee, or you can \"\"abstain\"\" from voting your shares. An \"\"abstain\"\" vote may or may not affect a director's election. Each company must disclose how \"\"abstain\"\" or \"\"withhold\"\" votes affect an election in its proxy statement. This information is often found toward the beginning of the proxy statement under a heading such as \"\"Votes Required to Adopt a Proposal\"\" or \"\"How Your Votes Are Counted.\"\" Proposals other than an election of directors: Matters other than voting on the election of directors, like voting on shareholder proposals, are typically approved by a vote of a majority of the shares voting or present at the meeting. In this situation, you are usually given the choice to vote your shares \"\"for\"\" or \"\"against\"\" a proposal, or to \"\"abstain\"\" from voting on it. Again, the effect of an \"\"abstain\"\" vote may depend on the specific voting rule that applies.

To prevent a single holdout from keeping say the very last share for one million dollars or the like on the open market, they would generally propose to the board of directors the buyout terms with a price per share, and most corporate charters are written such that the directors' vote binds minority shareholders to buyout or merger decisions.

Or, if they can get a supermajority (90% in the US), they don't even need a vote. Usually, a buying company's first option is a \"\"friendly merger\"\"; they approach the board of directors (or the direct owners of a private company) and make a \"\"tender offer\"\" to buy the company by purchasing their controlling interest. The board, if they find the offer attractive enough, will agree, and usually their support (or the outright sale of shares) will get the company the 51% they need. Failing the first option, the buying company's next strategy is to make the same tender offer on the open market. This must be a public declaration and there must be time for the market to absorb the news before the company can begin purchasing shares on the open market. The goal is to acquire 51% of the total shares in existence. Not 51% of market cap; that's the number (or value) of shares offered for public trading. You could buy 100% of Facebook's market cap and not be anywhere close to a majority holding (Zuckerberg himself owns 51% of the company, and other VCs still have closely-held shares not available for public trading). That means that a company that doesn't have 51% of its shares on the open market is pretty much un-buyable without getting at least some of those private shareholders to cash out. But, that's actually pretty rare; some of your larger multinationals may have as little as 10% of their equity in the hands of the upper management who would be trying to resist such a takeover. At this point, the company being bought is probably treating this as a \"\"hostile takeover\"\". They have options, such as: However, for companies that are at risk of a takeover, unless management still controls enough of the company that an overruling public stockholder decision would have to be unanimous, the shareholder voting body will often reject efforts to activate these measures, because the takeover is often viewed as a good thing for them; if the company's vulnerable, that's usually because it has under-performing profits (or losses), which depresses its stock prices, and the buying company will typically make a tender offer well above the current stock value. Should the buying company succeed in approving the merger, any \"\"holdouts\"\" who did not want the merger to occur and did not sell their stock are \"\"squeezed out\"\"; their shares are forcibly purchased at the tender price, or exchanged for equivalent stock in the buying company (nobody deals in paper certificates anymore, and as of the dissolution of the purchased company's AOI such certs would be worthless), and they either move forward as shareholders in the new company or take their cash and go home.\"", "title": "" }, { "docid": "345400", "text": "Why?

Instead of every citizen having a vote, votes are allocated on the basis of share ownership. In the most basic form, each share you own gives you 1 vote. In most public companies, very few shareholders vote [because their vote is statistically meaningless, and they have no particular insight into what they want in their Board]. This means that often the Board is voted in by a \"\"plurality\"\" [ie: 10%-50%] of shareholders who are actually large institutions (like investment firms or pension funds which own many shares of the company). Now, what do shareholders actually \"\"vote on\"\"? You vote to elect individuals to be members of the Board of Directors (\"\"BoD\"\"). The BoD is basically an overarching committee that theoretically steers the company in whatever way they feel best represents the shareholders (because if they do not represent the shareholders, they will get voted out at the next shareholder meeting). The Board members are typically senior individuals with experience in either that industry or a relevant one (ie: someone who was a top lawyer may sit on the BoD and be a member of some type of 'legal issues committee'). These positions typically pay some amount of money, but often they are seen as a form of high prestige for someone nearing / after retirement. It is not typically a full time job. It will typically pay far, far less than the role of CEO at the same company. The BoD meets periodically, to discuss issues regarding the health of the company. Their responsibility is to act in the interests of the shareholders, but they themselves do not necessarily own shares in the company. Often the BoD is broken up into several committees, such as an investment committee [which reviews and approves large scale projects], a finance committee [which reviews and approves large financial decisions, such as how to get funding], an audit committee [which reviews the results of financial statements alongside the external accountants who audit them], etc. But arguably the main role of the BoD is to hire the Chief Executive Officer and possibly other high level individuals [typically referred to as the C-Suite executives, ie Chief Financial Officer, Chief Operating Officer, etc.] The CEO is the Big Cheese, who then typically has authority to rule everyone below him/her. Typically there are things that the Big Cheese cannot do without approval from the board, like start huge investment projects requiring a lot of spending. So the Shareholders own the company [and are therefore entitled to receive all the dividends from profits the company earns] and elects members of the Board of Directors, the BoD oversees the company on the Shareholders' behalf, and the CEO acts based on the wishes of the BoD which hires him/her. So how do you get to be a member of the Board, or the CEO? You become a superstar in your industry, and go through a similar process as getting any other job. You network, you make contacts, you apply, you defend yourself in interviews. The shareholders will elect a Board who acts in their interests. And the Board will hire a CEO that they feel can carry out those interests. If you hold a majority of the shares in a company, you could elect enough Board members that you could control the BoD, and you could then be guaranteed to be hired as the CEO. If you own, say, 10% of the shares you will likely be able to elect a few people to the Board, but maybe not enough to be hired by the Board as the CEO.

Earnings would be just the corporation's accumulation of cash due to the operation of its business. Perhaps if cash was needed for a particular reason immediately, a business may consider selling a division or group of assets to another party, and using the proceeds for a different part of the business. Debt is money that (to put it simply) the corporation legally must repay to the lender, likely with periodic interest payments. Apart from the interest payments (if any) and the principal (original amount leant), the lender has no additional rights to the value of the company. There are, basically, 2 types of corporate debt: bank debt, and bonds. Bank debt is just the corporation taking on a loan from a bank. Bonds are offered to the public - ie: you could potentially buy a \"\"Tesla Bond\"\", where you give Tesla $1k, and they give you a stated interest rate over time, and principal repayments according to a schedule. Which type of debt a corporation uses will depend mostly on the high cost of offering a public bond, the relationships with current banks, and the interest rates the corporation thinks it can get from either method. Equity [or, shares] is money that the corporation (to put it simply) likely does not have a legal obligation to repay, until the corporation is liquidated (sold at the end of its life) and all debt has already been repaid. But when the corporation is liquidated, the shareholders have a legal right to the entire value of the company, after those debts have been paid. So equity holders have higher risk than debt holders, but they also can share in higher reward. That is why stock prices are so volatile - the value of each share fluctuates based on the perceived value of the entire company. Some equity may be offered with specific rules about dividend payments - maybe they are required [a 'preferred' share likely has a stated dividend rate almost like a bond, but also likely has a limited value it can ever receive back from the corporation], maybe they are at the discretion of the board of directors, maybe they will never happen. There are 2 broad ways for a corporation to get money from equity: a private offering, or a public offering. A private offering could be a small mom and pop store asking their neighbors to invest 5k so they can repair their business's roof, or it could be an 'Angel Investor' [think Shark Tank] contributing significant value and maybe even taking control of the company. Perhaps shares would be offered to all current shareholders first. A public offering would be one where shares would be offered up to the public on the stock exchange, so that anyone could subscribe to them. Why a corporation would use any of these different methods depends on the price it feels it could get from them, and also perhaps whether there are benefits to having different shareholders involved in the business [ie: an Angel investor would likely be involved in the business to protect his/her investment, and that leadership may be what the corporation actually needs, as much or more than money]. Whether a corporation chooses to gain cash from earnings, debt, or equity depends on many factors, including but not limited to: (1) what assets / earnings potential it currently has; (2) the cost of acquiring the cash [ie: the high cost of undergoing a public offering vs the lower cost of increasing a bank loan]; and (3) the ongoing costs of that cash to both the corporation and ultimately the other shareholders - ie: a 3% interest rate on debt vs a 6% dividend rate on preferred shares vs a 5% dividend rate on common shares [which would also share in the net value of the company with the other current shareholders]. In summary: Earnings would be generally preferred, but if the company needs cash immediately, that may not be suitable. Debt is generally cheap to acquire and interest rates are generally lower than required dividend rates. Equity is often expensive to acquire and maintain [either through dividend payments or by reduction of net value attributable to other current shareholders], but may be required if a new venture is risky. ie: a bank/bondholder may not want to lend money for a new tech idea because it is too risky to just get interest from - they want access to the potential earnings as well, through equity.\"", "title": "" }, { "docid": "226721", "text": "IANAL.

In the novel he is the one to first describe Erik , saying , `` He is extraordinarily thin and his dress-coat hangs on a skeleton frame . His eyes are so deep that you can hardly see the fixed pupils . You just see two big black holes , as in a dead man 's skull . His skin , which is stretched across his bones like a drumhead , is not white , but a nasty yellow . His nose is so little worth talking about that you ca n't see it side-face ; and the absence of that nose is a horrible thing to look at . All the hair he has is three or four long dark locks on his forehead and behind his ears . '' In the first chapter he was found to be hanged in the third cellar between a flat and a set piece from Le roi de Lahore , right next to the entrance to the Phantom 's torture chamber . In the Lon Chaney silent film by Universal Pictures he is portrayed by Bernard Siegel and is given a brother Simon Buquet ( Gibson Gowland ) . In the film , Joseph tells the ballerinas about the Phantom 's face . His body is later found to have been hanged by the Phantom . Simon swears revenge against the Phantom and leads an angry mob into his lair and through the streets . The discovery of Joseph 's dead body comes at different points in the movie depending on whether it is the original 1925 cut or the 1929 foreign cut ( in the latter 's case Joseph 's body is not found until right before Simon starts the mob ) . In the 1962 Herbert Lom movie by Hammer Film Productions an unnamed stagehand is found hanged . He is obviously supposed to be Joseph Buquet . In the 1989 Robert Englund movie by Metro-Goldwyn-Mayer , Joseph Buquet blames the Phantom for a falling sandbag that was actually his own fault . This angers the Phantom , causing him to kill Buquet . In Andrew Lloyd Webber 's 1986 stage version , Buquet describes the Phantom 's appearance to the ballet chorus and demonstrates the way to counter his `` magical lasso '' ( the Punjab lasso , the Phantom 's weapon for strangling victims ) . Cautioned by Madame Giry against speaking out , he is later found strangled and hanging from the stage rafters during a performance , throwing the audience into chaos . In Nicholas Meyer 's novel The Canary Trainer , Erik kills him as punishment for Buquet declaring his love to Christine Daaé .

Halving Heart Attack Risk

METHODS: In 1990, 28,333 men and women in Miyagi Prefecture in rural northern Japan (40-64 year of age) completed a self-administered questionnaire. A lifestyle score was calculated by adding the number of high-risk practices (smoking, consuming > or = 22.8 g alcohol/d, walking < 1 hr/d, body mass index < 18.5 or > or = 30.0). Cox regression was used to estimate relative risk (RR) of mortality according to the lifestyle score, with adjustment for age, education, marital status, past history of diseases, and dietary variables. During 11 years of follow-up, 1,200 subjects had died. RESULTS: We observed linear increase in risk of death associated with increasing number of high-risk practices: compared with men who had no high-risk practices, multivariate RRs for men who had 1 to 4 practices were 1.20, 1.66, 1.94, and 3.96, respectively (P for trend<0.001), and corresponding RRs for women were 1.31, 2.14, 3.98, 5.56, respectively (P for trend<0.001). A unit increase in the number of high-risk practices corresponded to being 2.8 and 4.8 years older for men and women, respectively. CONCLUSIONS: In this prospective cohort study of middle-aged men and women in rural Japan, a larger number of high-risk practices was associated with linear increase in risk of all-cause mortality.", "title": "Health practices and mortality in Japan: combined effects of smoking, drinking, walking and body mass index in the Miyagi Cohort Study." }, { "docid": "MED-2597", "text": "Since the beginning of the 1990s, increasing evidence supports beneficial effects of nut consumption on health.

OBJECTIVES: To measure the burden of diseases, injuries, and leading risk factors in the United States from 1990 to 2010 and to compare these measurements with those of the 34 countries in the Organisation for Economic Co-operation and Development (OECD) countries. DESIGN: We used the systematic analysis of descriptive epidemiology of 291 diseases and injuries, 1160 sequelae of these diseases and injuries, and 67 risk factors or clusters of risk factors from 1990 to 2010 for 187 countries developed for the Global Burden of Disease 2010 Study to describe the health status of the United States and to compare US health outcomes with those of 34 OECD countries. Years of life lost due to premature mortality (YLLs) were computed by multiplying the number of deaths at each age by a reference life expectancy at that age. Years lived with disability (YLDs) were calculated by multiplying prevalence (based on systematic reviews) by the disability weight (based on population-based surveys) for each sequela; disability in this study refers to any short- or long-term loss of health. Disability-adjusted life-years (DALYs) were estimated as the sum of YLDs and YLLs. Deaths and DALYs related to risk factors were based on systematic reviews and meta-analyses of exposure data and relative risks for risk-outcome pairs. Healthy life expectancy (HALE) was used to summarize overall population health, accounting for both length of life and levels of ill health experienced at different ages. RESULTS: US life expectancy for both sexes combined increased from 75.2 years in 1990 to 78.2 years in 2010; during the same period, HALE increased from 65.8 years to 68.1 years. The diseases and injuries with the largest number of YLLs in 2010 were ischemic heart disease, lung cancer, stroke, chronic obstructive pulmonary disease, and road injury. Age-standardized YLL rates increased for Alzheimer disease, drug use disorders, chronic kidney disease, kidney cancer, and falls. The diseases with the largest number of YLDs in 2010 were low back pain, major depressive disorder, other musculoskeletal disorders, neck pain, and anxiety disorders. As the US population has aged, YLDs have comprised a larger share of DALYs than have YLLs. The leading risk factors related to DALYs were dietary risks, tobacco smoking, high body mass index, high blood pressure, high fasting plasma glucose, physical inactivity, and alcohol use. Among 34 OECD countries between 1990 and 2010, the US rank for the age-standardized death rate changed from 18th to 27th, for the age-standardized YLL rate from 23rd to 28th, for the age-standardized YLD rate from 5th to 6th, for life expectancy at birth from 20th to 27th, and for HALE from 14th to 26th. CONCLUSIONS AND RELEVANCE: From 1990 to 2010, the United States made substantial progress in improving health. Life expectancy at birth and HALE increased, all-cause death rates at all ages decreased, and age-specific rates of years lived with disability remained stable. However, morbidity and chronic disability now account for nearly half of the US health burden, and improvements in population health in the United States have not kept pace with advances in population health in other wealthy nations.", "title": "The state of US health, 1990-2010: burden of diseases, injuries, and risk factors." }, { "docid": "MED-4300", "text": "BACKGROUND AND AIMS: Nuts have been part of the human diet since prehistoric times. The aim of the present article is to describe the most important historical and cultural aspects of nut consumption throughout history.

Particular emphasis is placed on the healthy and nutritional attributes that nuts have had throughout history. We also consider the role of the first globalization of food--the exchange of nuts between continents--and discuss the symbolism that nuts have had for humans throughout history in the context of cultural aspects of the Mediterranean region. CONCLUSIONS: Nuts and fruits are probably the earliest foods consumed by humans and are considered to be important because of their nutritional properties.

Subsequently, many dietary intervention trials investigated the effects of nut consumption on blood lipid levels. The objectives of this study were to estimate the effects of nut consumption on blood lipid levels and to examine whether different factors modify the effects. METHODS: We pooled individual primary data from 25 nut consumption trials conducted in 7 countries among 583 men and women with normolipidemia and hypercholesterolemia who were not taking lipid-lowering medications. In a pooled analysis, we used mixed linear models to assess the effects of nut consumption and the potential interactions. RESULTS: With a mean daily consumption of 67 g of nuts, the following estimated mean reductions were achieved: total cholesterol concentration (10.9 mg/dL [5.1% change]), low-density lipoprotein cholesterol concentration (LDL-C) (10.2 mg/dL [7.4% change]), ratio of LDL-C to high-density lipoprotein cholesterol concentration (HDL-C) (0.22 [8.3% change]), and ratio of total cholesterol concentration to HDL-C (0.24 [5.6% change]) (P < .001 for all) (to convert all cholesterol concentrations to millimoles per liter, multiply by 0.0259). Triglyceride levels were reduced by 20.6 mg/dL (10.2%) in subjects with blood triglyceride levels of at least 150 mg/dL (P < .05) but not in those with lower levels (to convert triglyceride level to millimoles per liter, multiply by 0.0113). The effects of nut consumption were dose related, and different types of nuts had similar effects on blood lipid levels. The effects of nut consumption were significantly modified by LDL-C, body mass index, and diet type: the lipid-lowering effects of nut consumption were greatest among subjects with high baseline LDL-C and with low body mass index and among those consuming Western diets.

Data synthesis We combined study level death outcomes from exercise and drug trials using random effects network meta-analysis. Results We included 16 (four exercise and 12 drug) meta-analyses. Incorporating an additional three recent exercise trials, our review collectively included 305 randomised controlled trials with 339 274 participants. Across all four conditions with evidence on the effectiveness of exercise on mortality outcomes (secondary prevention of coronary heart disease, rehabilitation of stroke, treatment of heart failure, prevention of diabetes), 14 716 participants were randomised to physical activity interventions in 57 trials. No statistically detectable differences were evident between exercise and drug interventions in the secondary prevention of coronary heart disease and prediabetes.

Purpose To investigate the impact of different dosages of pistachios on body weight, blood pressure, blood lipids, blood glucose and insulin in subjects with metabolic syndrome. Methods Ninety subjects with metabolic syndrome (consistent with 2005 International Diabetes Federation metabolic syndrome standard without diabetes) were enrolled in three endocrinology outpatient clinics in Beijing. All subjects received dietary counseling according to the guidelines of the American Heart Association Step I diet. After a 4 week run-in, subjects were randomized to consume either the recommended daily serving of 42 g pistachios (RSG), a higher daily serving of 70 g pistachio (HSG) or no pistachios (DCG) for 12 weeks. Results Subjects in all three groups were matched at baseline for BMI: DCG 28.03 ± 4.3; RSG 28.12 ± 3.22; and HSG 28.01 ± 4.51 kg/m2. There were no significant changes in body weight or BMI in any groups during the study nor any change from baseline at any time point in any group.

The recent recognition of nuts as \"heart-healthy\" foods by the U.S. Food and Drug Administration has given a major boost to the positive image of nuts. Nut consumption has been associated with several health benefits, such as antioxidant, hypocholesterolemic, cardioprotective, anticancer, anti-inflammatory, and antidiabetic benefits, among other functional properties.

In addition, because nuts are energy-dense foods with high-fat content, there is a misconception among consumers that increased consumption may lead to unwanted gain in body weight with the risk of developing overweight/obesity. Nonetheless, available epidemiologic studies and short-term controlled feeding trials have supported the theory that the inclusion of nuts in the typical diet does not induce weight gain, despite an expected increase in total caloric intake.

The first pandemic, induced by beriberi, was caused by the industrial revolution altering the nutritional composition of rice. By 1892 a simple working knowledge, then at hand, could have terminated the beriberi plague; however, orthodox medicine being then enchanted with the false concept that all disease was caused by germs, permitted millions of Asians to die needlessly of beriberi by refusing to tell them to eat rice bran or to drink rice bran tea. A second pandemic of heart attack deaths, called myocardial infarction (MI), struck the developed nations of the Western World in full force after 1930. As a hypothesis, it is suggested that this MI pandemic, still raging today, was caused by a change in food processing that occurred after 1920, when the new oil seed industry introduced into our food three greatly harmful lipid substances. The unnatural trans-trans isomer of linoleic acid, which had never been in human food prior to 1920 and which entered our food in margarines and refined oils, blocked the conversion of natural cis-cis linoleic acid to prostaglandin E1, which tends to prevent MI, both by acting as a vasodilator and by minimizing platelet aggregation. Harmful lactones were also introduced into our food, increasing the risk of MI by decreasing the fibrinolytic activity of our blood. The oil seed industry also introduced into our diet free radical lipid peroxides that make the myocardium more vulnerable to infarction. It is suggested that except for the one in 500 of us who is afflicted by familial hypercholesterolemia, the cholesterol concept of MI is as false today as was the concept in 1900 that germs caused beriberi.

The blood platelets are of significant importance in medicine. These cells are involved in many physiological processes, particularly haemostasis through their ability to aggregate and form clots in response to activation. In addition, these dynamic cells display activities that extend beyond thrombosis, including an important role in initiating and sustaining vascular inflammation. The expansion of knowledge from basic and clinical research has highlighted the critical position of platelets in several inflammatory diseases such as arthritis and atherosclerosis. Platelets are emerging as important mediators of inflammation and provide important signals to mediate phenotype of other blood and vascular cells. The important role of platelets in arterial thrombosis and the onset of acute myocardial infarction after atherosclerotic plaque rupture make inhibition of platelet aggregation a critical step in preventing thrombotic events associated with stroke, heart attack, and peripheral arterial thrombosis. However, the use of platelet inhibitors for thrombosis prevention must seek a delicate balance between inhibiting platelet activation and an associated increased bleeding risk. The aim of this review is to up-date the knowledge on platelets physiology and dysfunction in pathologies, such as diabetes mellitus, hypercholesterolemia, and hypertension, emphasizing the link between platelets and the inflammation-related atherosclerosis.

Short-term use (less than 14 days) demonstrates dose-dependent damage of prescribed NSAIDs; the damage is proportional to the acidity of the drugs and not seen with Cyclooxygenase-2 (COX-2) selective inhibitors that have a pKa over 7.0. There have not been any serious outcomes, such as bleeding or perforation in these studies, and Helicobacter pylori (HP) plays no role in this damage. Long-term (3 months or more) endoscopy studies in patients show ulcer rates from 15%-35% with the various NSAIDs, but serious outcomes are exceedingly rare. Epidemiological studies show an association between NSAID intake and serious events. Ibuprofen is consistently at the lower end of toxicity rankings, whereas ketorolac and azapropazone are the worst.

Triggers for GBS include infection and (rarely) vaccination; cross-reactivity between infectious and neural epitopes has been well demonstrated, particularly for Campylobacter jejuni and motor axonal forms of GBS in which non-protein gangliosides are antigenic. Most people are probably exposed to a GBS trigger, but only rarely does the disease develop. We propose that GBS illustrates competing determinants of the immune system's decision about whether to mount a response, and that in unlucky affected individuals, co-presentation of cross-reactive antigens with danger signals activating pattern-recognition receptors overcomes normal self-recognition such that a primary response is initiated that attacks the nerve. Then, in most cases of GBS, the response rapidly turns off, and second attacks rarely occur. This suggests active restoration of tolerance, and specific privileged site attributes of nerve and declining danger signals as the trigger wanes may contribute to this restoration. Standard immunosuppression has not been effective in GBS. We suggest this is because immune tolerance is already being restored by the time such therapies are initiated. This in turn suggests that improvements in GBS outcomes are likely to come from better protection of the nerve cells under attack while normal resumption of tolerance is permitted to proceed rather than exploring more aggressive immunosuppressive approaches.", "title": "Guillain-barré syndrome: modern theories of etiology." }, { "docid": "MED-3517", "text": "Preliminary studies have shown that repeated nasal applications of capsaicin prevented the occurrence of cluster headache attacks.

OBJECTIVE: To evaluate the association of fruit and vegetable consumption with risk for coronary heart disease. DESIGN: Prospective cohort study. SETTING: The Nurses' Health Study and the Health Professionals' Follow-Up Study. PARTICIPANTS: 84 251 women 34 to 59 years of age who were followed for 14 years and 42 148 men 40 to 75 years who were followed for 8 years. All were free of diagnosed cardiovascular disease, cancer, and diabetes at baseline. MEASUREMENTS: The main outcome measure was incidence of nonfatal myocardial infarction or fatal coronary heart disease (1127 cases in women and 1063 cases in men). Diet was assessed by using food-frequency questionnaires. RESULTS: After adjustment for standard cardiovascular risk factors, persons in the highest quintile of fruit and vegetable intake had a relative risk for coronary heart disease of 0.80 (95% CI, 0.69 to 0.93) compared with those in the lowest quintile of intake.

In this study we investigated the relation of these risk scores to the early atherosclerotic lesions. METHODS: We measured atherosclerotic lesions in the left anterior descending coronary artery, right coronary artery, and abdominal aorta and the coronary heart disease risk factors in persons 15 to 34 years of age who died as a result of external causes and were autopsied in forensic laboratories. RESULTS: Risk scores computed from the modifiable risk factors were associated with prevalence of microscopically demonstrable lesions of atherosclerosis (American Heart Association grade 1) in the left anterior descending coronary artery and with the extent of the earliest detectable gross lesion (fatty streaks) in the right coronary artery and abdominal aorta. Risk scores computed from the modifiable risk factors also were associated with prevalence of lesions of higher degrees of microscopic severity (intermediate as well as advanced) in the left anterior descending coronary artery and with extent of lesions of higher degrees of severity (intermediate and raised lesions) in the right coronary artery and abdominal aorta.

Any factor that may affect the regulation and amount of aggression within a farmed system, for instance, feeding the beta-adrenoreceptor agonist ractopamine (RAC), is therefore worthy of investigation. The objectives of this study were to assess the effects of the widely used swine feed additive RAC, considering also the effects of sex and social rank on aggressiveness and concentrations of brain amines, neurotransmitters essential for controlling aggression, in finishing pigs. Thirty-two barrows and 32 gilts (4 pigs/pen by sex) were fed either a control diet or a diet with RAC (Paylean, Elanco Animal Health, Greenfield, IN) added (5 mg/kg for 2 wk, followed by 10 mg/kg for 2 wk). The top dominant and bottom subordinate pigs (16 pigs/sex) in each pen were determined after mixing by a 36-h period of continuous behavioral observation. These pigs were then subjected to resident-intruder tests (maximum 300 s) during the feeding trial to measure aggressiveness. At the end of wk 4, the amygdala, frontal cortex, hypothalamus, and raphe nuclei were dissected and analyzed for concentrations of dopamine (DA); serotonin (5-HT); their metabolites 3,4-dihydroxyphenyl acetic acid (DOPAC) and homovanillic acid, and 5-hydroxyindoleacetic acid (5-HIAA), respectively; norepinephrine; and epinephrine using HPLC. Ractopamine-fed gilts performed more attacks during the first 30 s of testing than pigs in all other subgroups (P < 0.05). By the end of the resident-intruder test (300 s), the dominant control gilts and barrows, and both dominant and subordinate RAC-fed gilts performed the greatest percentage of attacks (P < 0.05). Gilts had decreased norepinephrine and DOPAC concentrations in the amygdala and frontal cortex, and when fed RAC, gilts also had the least 5-HIAA concentration and greatest DA turnover rate in the amygdala (P < 0.05). The 5-HT concentration was less in the frontal cortex of gilts compared with barrows and in the raphe nuclei (single site for brain 5-HT synthesis) of dominant gilts (P < 0.05). Ractopamine may be affecting aggressive behavior through indirect action on central regulatory mechanisms such as the DA system.

In 1998, after an average follow-up of 25 years, surviving male participants were asked to complete the International Index of Erectile Function (IIEF-5), which allows stratification of ED into five groups. RESULTS: Sixty-eight percent of the surviving men returned, and 60% completed the IIEF-5 questionnaire. Respondents had more favorable levels of all heart disease risk factors at baseline than non-respondents. At baseline, the average age of the 570 ED study participants was 46 years; at follow-up, their average age was 72 years. Mean age, body mass index, cholesterol, and triglycerides were each significantly associated with an increased risk of ED.

Compared with pioglitazone, use of rosiglitazone was associated with a statistically significant increase in the odds of myocardial infarction (n=15 studies; odds ratio 1.16, 95% confidence interval 1.07 to 1.24; P<0.001; I2=46%), congestive heart failure (n=8; 1.22, 1.14 to 1.31; P<0.001; I2=37%), and death (n=8; 1.14, 1.09 to 1.20; P<0.001; I2=0%). Numbers needed to treat to harm (NNH), depending on the population at risk, suggest 170 excess myocardial infarctions, 649 excess cases of heart failure, and 431 excess deaths for every 100 000 patients who receive rosiglitazone rather than pioglitazone.

Here's an FAQ from the IRS: Q-8: Does a taxpayer who “mines” virtual currency (for example, uses computer resources to validate Bitcoin transactions and maintain the public Bitcoin transaction ledger) realize gross income upon receipt of the virtual currency resulting from those activities? A-8: Yes, when a taxpayer successfully “mines” virtual currency, the fair market value of the virtual currency as of the date of receipt is includible in gross income. See Publication 525, Taxable and Nontaxable Income, for more information on taxable income.Q-9: Is an individual who “mines” virtual currency as a trade or business subject to self-employment tax on the income derived from those activities? A-9: If a taxpayer’s “mining” of virtual currency constitutes a trade or business, and the “mining” activity is not undertaken by the taxpayer as an employee, the net earnings from self-employment (generally, gross income derived from carrying on a trade or business less allowable deductions) resulting from those activities constitute selfemployment income and are subject to the self-employment tax.

If the amount of income tax withheld from your salary or pension is not enough, or if you receive income such as interest, dividends, alimony, self-employment income, capital gains, prizes and awards, you may have to make estimated tax payments. If you are in business for yourself, you generally need to make estimated tax payments. Estimated tax is used to pay not only income tax, but other taxes such as self-employment tax and alternative minimum tax. I think that is crystal clear that you're paying income tax as well as self-employment tax. To expand a bit, you seem to be confusing self-employment tax and estimated tax, which are not only two different things, but two different kinds of things. One is a tax, and the other is just a means of paying your taxes. \"\"Self-employment tax\"\" refers to the Social Security and Medicare taxes that you must pay on your self-employment income. This is an actual tax that you owe. If you receive a W-2, half of it is \"\"invisibly\"\" paid by your employer, and half of it is paid by you in the form of visible deductions on your pay stub. If you're self-employed, you have to pay all of it explicitly. \"\"Estimated tax\"\" does not refer to any actual tax levied on anyone. A more pedantically correct phrasing would be \"\"estimated tax payment\"\". Estimated taxes are just payments that you make to the IRS to pay tax you expect to owe. Whether you have to make such payments depends on how much tax you owe and whether you've paid it by other means. You may need to pay estimated tax even if you're not self-employed, although this would be unusual. (It could happen, for instance, if you realized large capital gains over the year.) You also may be self-employed but not need to pay estimated tax (if, for instance, you also have a W-2 job and you reduce your withholding allowances to have extra tax withheld). That said, if you earn significant income from self-employment, you'll likely have to make estimated tax payments. These are prepayments of the income tax and Social Security/Medicare taxes you accrue based on your self-employment income. As Pete B. mentioned in his answer, a possible reason that your estiamtes are low is because some taxes have already been withheld from the paychecks you received so far during the year (while you were an employee).

The type of expenses that go here are: If you are considered an independent contractor (I presume this includes the value of goods, based on the first quoted paragraph above): Independent contractors get paid by cash or check with no withholding of any kind.

Based upon the IRS pages for Self-Employment Tax and Family Businesses, while you will not likely have to pay income tax until you make $6,300 in a year, you will still have to pay Social Security and Medicare taxes after the first $400. Roughly this should be right about 16% of your income, so if you make $6000 you'll owe just under $1000 (and be keeping the other $5000). If your income grows even more, you may want to learn about business expense deductions. This would allow you to pay for things like advertisement, software, a new computer for development purposes, etc, and deduct the expenses out of your income so you pay less in taxes.

Significantly, it is likely that if you have additional income beyond income from that employer, it is likely to be taxed at your highest tax rate, as the employer will likely calculate the tax due based on their income being the only income you have in that year. *Edit based on emphasis in question: I'm not from Singapore nor am I a lawyer, but based on my reading of the IRAS website, it looks like you do not have to file if you have no other source of income, because they have a No-Filing Service which takes income information from your employer automatically and generates a tax bill, which presumably would be fully paid in your case. This only aplies if you have no other sources of income, however; you still have to file if you have other sources of income since your employer would not know about them.

In other words, because your wife is technically self employed, she will owe both sides of payroll tax which is 15.3% of $38k = $5,800 on TOP of your federal income tax (which is the only thing the W-4 is instructing them about what amount to withhold). The huge advantage to a 1099, however, is that she's essentially self-employed which means ALL of the things she needs to run her business are deductible expenses. This includes her car, computer, home office, supplies, sometimes phone, gas, maintenance, travel expenses, sometimes entertainment, etc - which can easily bring her \"\"income\"\" down from $38k to lets say $23k, reducing both her federal income tax AND self-employment tax to apply to $15k less (saving lets say 50% of $15k = $7.5k with federal and self employment because your income is so high). She is actually supposed to pay quarterly taxes to make up for all of this. The easy way to do this is each quarter plug YOUR total salary + bonus and the tax YOU have paid so far (check your paystubs) into TurboTax along with her income so far and all of her expenses.

You have two options, one is to increase your income, the other is to reduce your expenditure. Paying off debt will also help but that may not apply to you. Most people find it easier to reduce expenditure, so I will explain that first of all. Then make sure you track your actual expenditure agains the budget, check it daily and make sure it is accurate, if you spend some money you didn't budget for then mark that down and make sure you budget for it going forward. Most people are surprised at how much they are actually spending, especially on trivial things like coffee, lunch at work etc. You will then find you can start to reduce this expenditure, maybe by bringing lunch to work, skipping coffee every other day etc. By doing a budget you can reduce your expenditure and hopefully have some money left over to save - put a line in your budget marked savings (ideally on the day you get paid so you don't spend it)! If you ned to save $x by Y date then work out how much that works out in a month and put that into your budget, if you haven't got enough spare to do that then onto stage 2 With regards to increasing income, the obvious way is to do some overtime at work - can you do that? Alternatively you can get a part-time job, maybe a hobby that pays money? I personally enjoy building web-sites as a hobby and I get about $20 a month from advertising on those, it's not much but it adds up over time. Finally how to actually save, what methods are there? Lots of options here, personally I buy shares with my savings, making sure I pick stocks that are currently cheap - this is quite risky and may not suit you but it works for me as I don't sell the shares until I actually need the money. Other options are regular savings accounts that pay a bonus after you've had the money in for (usually) 12 months etc. They tend to pay a bonus at the end so you are incentivised to not touch your cash but you can get it out if you really need it.

If the plan is to increase hours in your current, you need to allow for your needs (sleep, rest, etc) and also convince your employer they will benefit by paying you to work more hours. If your intent is to increase your hourly rate, you need to convince a current or prospective employer that you have the capacity, skills, etc to deliver more on the job, so you are worth paying more. If your intent is to get qualifications so you can get a better paying job, work out how much effort (studying, etc) you will apply, over how long, what expenses you will carry (fees, textbooks, etc), and how long you will carry them for (will you accept working some years in a higher paying job, to clear the debt?).

The loan principal appears as a liability on your personal balance sheet, which you could use, for example, in determining net worth. The principal amount in your payment should be applied to reduce the liability account. The interest payment goes into the expense account. Another way to look at it is that the principal, while it does reduce your cash account, can be thought of as an internal transfer to the liability account, thus reducing the size of the liability. The interest payment cannot. Aside: From this perspective, the value of the home is an asset, and the difference between the asset account and the loan liability account is the equity in the house (as pointed out in different language by the accepted answer).

MeCP2 influences the synaptic maturation of neurons.
[ { "docid": "10009203", "text": "As the nervous system develops, there is an inherent variability in the connections formed between differentiating neurons. Despite this variability, neural circuits form that are functional and remarkably robust. One way in which neurons deal with variability in their inputs is through compensatory, homeostatic changes in their electrical properties. Here, we show that neurons also make compensatory adjustments to their structure. We analysed the development of dendrites on an identified central neuron (aCC) in the late Drosophila embryo at the stage when it receives its first connections and first becomes electrically active. At the same time, we charted the distribution of presynaptic sites on the developing postsynaptic arbor. Genetic manipulations of the presynaptic partners demonstrate that the postsynaptic dendritic arbor adjusts its growth to compensate for changes in the activity and density of synaptic sites. Blocking the synthesis or evoked release of presynaptic neurotransmitter results in greater dendritic extension. Conversely, an increase in the density of presynaptic release sites induces a reduction in the extent of the dendritic arbor. These growth adjustments occur locally in the arbor and are the result of the promotion or inhibition of growth of neurites in the proximity of presynaptic sites. We provide evidence that suggest a role for the postsynaptic activity state of protein kinase A in mediating this structural adjustment, which modifies dendritic growth in response to synaptic activity. These findings suggest that the dendritic arbor, at least during early stages of connectivity, behaves as a homeostatic device that adjusts its size and geometry to the level and the distribution of input received. The growing arbor thus counterbalances naturally occurring variations in synaptic density and activity so as to ensure that an appropriate level of input is achieved.", "title": "Structural Homeostasis: Compensatory Adjustments of Dendritic Arbor Geometry in Response to Variations of Synaptic Input " } ]

Interestingly, while neurons overexpressing this mutant failed to enhance axonal and dendritic process elongation, the complexity of their axonal and dendritic processes remained significantly elevated.

This review will focus on the current knowledge of the synaptic alterations produced by mutations of the gene MeCP2 in mouse models of RS and will highlight prospects experimental therapies currently in use. Different experimental approaches have revealed that RS could be the consequence of an impairment in the homeostasis of synaptic transmission in specific brain regions. Indeed, several forms of experience-induced neuronal plasticity are impaired in the absence of MeCP2. Based on the results presented in this review, it is reasonable to propose that understanding how the brain is affected by diseases such as RS is at reach. This effort will bring us closer to identify the neurobiological bases of human cognition.", "title": "Synaptic Determinants of Rett Syndrome" }, { "docid": "36637129", "text": "Reprogramming of somatic cells into pluripotency stem cell state has opened new opportunities in cell replacement therapy and disease modeling in a number of neurological disorders. It still remains unknown, however, to what degree the grafted human-induced pluripotent stem cells (hiPSCs) differentiate into a functional neuronal phenotype and if they integrate into the host circuitry. Here, we present a detailed characterization of the functional properties and synaptic integration of hiPSC-derived neurons grafted in an in vitro model of hyperexcitable epileptic tissue, namely organotypic hippocampal slice cultures (OHSCs), and in adult rats in vivo. The hiPSCs were first differentiated into long-term self-renewing neuroepithelial stem (lt-NES) cells, which are known to form primarily GABAergic neurons. When differentiated in OHSCs for 6 weeks, lt-NES cell-derived neurons displayed neuronal properties such as tetrodotoxin-sensitive sodium currents and action potentials (APs), as well as both spontaneous and evoked postsynaptic currents, indicating functional afferent synaptic inputs. The grafted cells had a distinct electrophysiological profile compared to host cells in the OHSCs with higher input resistance, lower resting membrane potential, and APs with lower amplitude and longer duration. To investigate the origin of synaptic afferents to the grafted lt-NES cell-derived neurons, the host neurons were transduced with Channelrhodopsin-2 (ChR2) and optogenetically activated by blue light. Simultaneous recordings of synaptic currents in grafted lt-NES cell-derived neurons using whole-cell patch-clamp technique at 6 weeks after grafting revealed limited synaptic connections from host neurons. Longer differentiation times, up to 24 weeks after grafting in vivo, revealed more mature intrinsic properties and extensive synaptic afferents from host neurons to the lt-NES cell-derived neurons, suggesting that these cells require extended time for differentiation/maturation and synaptogenesis. However, even at this later time point, the grafted cells maintained a higher input resistance. These data indicate that grafted lt-NES cell-derived neurons receive ample afferent input from the host brain. Since the lt-NES cells used in this study show a strong propensity for GABAergic differentiation, the host-to-graft synaptic afferents may facilitate inhibitory neurotransmitter release, and normalize hyperexcitable neuronal networks in brain diseases, for example, such as epilepsy.", "title": "Optogenetics reveal delayed afferent synaptogenesis on grafted human-induced pluripotent stem cell-derived neural progenitors." }, { "docid": "980008", "text": "Mutations in the X-linked methyl-CpG-binding protein 2 (MECP2), encoding a transcriptional repressor, cause Rett syndrome and a variety of related neurodevelopmental disorders.

We overexpressed wild-type human protein in transgenic mice using a large genomic clone containing the entire human MECP2 locus. Detailed neurobehavioral and electrophysiological studies in transgenic line MeCP2(Tg1), which expresses MeCP2 at approximately 2-fold wild-type levels, demonstrated onset of phenotypes around 10 weeks of age.

We report two major components of morphological change in the aging C. elegans nervous system: (1) accumulation of novel outgrowths from specific neurons, and (2) physical decline in synaptic integrity. Novel outgrowth phenotypes, including branching from the main dendrite or new growth from somata, appear at a high frequency in some aging neurons, but not all. Mitochondria are often associated with age-associated branch sites. Lowered insulin signaling confers some maintenance of ALM and PLM neuron structural integrity into old age, and both DAF-16/FOXO and heat shock factor transcription factor HSF-1 exert neuroprotective functions. hsf-1 can act cell autonomously in this capacity. EM evaluation in synapse-rich regions reveals a striking decline in synaptic vesicle numbers and a diminution of presynaptic density size.

Because cGMP can broadly influence diverse ion-channels, kinases, and phosphodiesterases, pre- as well as post-synaptically, the precise identity of cGMP targets mediating spinal LTP, their mechanisms of action, and their locus in the spinal circuitry are still unclear. Here, we found that Protein Kinase G1 (PKG-I) localized presynaptically in nociceptor terminals plays an essential role in the expression of spinal LTP. Using the Cre-lox P system, we generated nociceptor-specific knockout mice lacking PKG-I specifically in presynaptic terminals of nociceptors in the spinal cord, but not in post-synaptic neurons or elsewhere (SNS-PKG-I(-/-) mice). Patch clamp recordings showed that activity-induced LTP at identified synapses between nociceptors and spinal neurons projecting to the periaqueductal grey (PAG) was completely abolished in SNS-PKG-I(-/-) mice, although basal synaptic transmission was not affected. Analyses of synaptic failure rates and paired-pulse ratios indicated a role for presynaptic PKG-I in regulating the probability of neurotransmitter release. Inositol 1,4,5-triphosphate receptor 1 and myosin light chain kinase were recruited as key phosphorylation targets of presynaptic PKG-I in nociceptive neurons. Finally, behavioural analyses in vivo showed marked defects in SNS-PKG-I(-/-) mice in several models of activity-induced nociceptive hypersensitivity, and pharmacological studies identified a clear contribution of PKG-I expressed in spinal terminals of nociceptors. Our results thus indicate that presynaptic mechanisms involving an increase in release probability from nociceptors are operational in the expression of synaptic LTP on spinal-PAG projection neurons and that PKG-I localized in presynaptic nociceptor terminals plays an essential role in this process to regulate pain sensitivity.", "title": "Presynaptically Localized Cyclic GMP-Dependent Protein Kinase 1 Is a Key Determinant of Spinal Synaptic Potentiation and Pain Hypersensitivity" }, { "docid": "17123316", "text": "Perturbations in neuregulin-1 (NRG1)/ErbB4 function have been associated with schizophrenia.

In hippocampal neurons, Wnt7a increases the number of excitatory synapses, whereas inhibitory synapses are unaffected.

Because of these special properties, GluN3A subunits act as a molecular brake to limit the plasticity and maturation of excitatory synapses, pointing toward GluN3A removal as a critical step in the development of neuronal circuitry.

Alanine mutations within the GluN3A endocytic motif inhibited clathrin-dependent internalization and led to accumulation of GluN3A-containing NMDARs at the cell surface, whereas mimicking phosphorylation of the tyrosine residue promoted internalization and reduced cell-surface expression as shown by immunocytochemical and electrophysiological approaches in recombinant systems and rat neurons in primary culture. We further demonstrate that the tyrosine residue is phosphorylated by Src family kinases, and that Src-activation limits surface GluN3A expression in neurons.

Natural phytochemicals containing phenolic compounds have been widely demonstrated to have the capability to prevent cancer metastasis. Among phenolic compounds, flavonoids are a very large subclass, and they are abundant in food and nutraceuticals. The number of reports demonstrating that flavonoids are an effective natural inhibitor of cancer invasion and metastasis is increasing in the scientific literature. Catechin derivatives, (−)-epigallocatechin-3-gallate, (−)-epigallocatechin, (−)-epicatechin-3-gallate,and (−)-epicatechin, are the most studied compounds in this topic so far; genistein/genistin, silibinin, quercetin, and anthocyanin have also been widely investigated for their inhibitory activities on invasion/metastasis. Other flavonoids in dietary vegetable foods that are responsible for anti-invasive and anti-metastatic activities of tumors include luteolin,apigenin, myricetin, tangeretin, kaempferol, glycitein, licoricidin,daidzein, and naringenin. To effectively overcome the metastatic cascade, including cell-cell attachment, tissue barrier degradation, migration, invasion, cell-matrix adhesion,and angiogenesis, it is essential that a bioactive compound prevent tumor cells from metastasizing. This review summarizes the effects of flavonoids on the metastatic cascade and the related proteins, the in vitro anti-invasive activity of flavonoids against cancer cells, and the effects of flavonoids on antiangiogenic and in vivo anti-metastatic models. The available scientific evidence indicates that flavonoids are a ubiquitous dietary phenolics subclass and exert extensive in vitro anti-invasive and in vivo anti-metastatic activities.", "title": "Flavonoids, a ubiquitous dietary phenolic subclass, exert extensive in vitro anti-invasive and in vivo anti-metastatic activities." }, { "docid": "MED-3553", "text": "Several epidemiological studies have indicated that abundant consumption of foods from plant origin is associated with a reduced risk of developing several types of cancers. This chemopreventive effect is related to the high content of these foods in phytochemicals, such as polyphenols, that interfere with several processes involved in cancer progression including tumor cell growth, survival and angiogenesis. In addition to the low intake of plant-based foods, increased body mass and physical inactivity have recently emerged as other important lifestyle factors influencing cancer risk, leading to the generation of low-grade chronic inflammatory conditions which are a key process involved in tumor progression. The objectives of the current study are to investigate the inhibitory effects of these polyphenols on angiogenesis triggered by an inflammatory cytokine (IL-6) and to determine the mechanisms underlying this action. We found that, among the tested polyphenols, apigenin and luteolin were the most potent angiogenesis inhibitors through their inhibitory effect on the inflammatory cytokine IL-6/STAT3 pathway. These effects resulted in modulation of the activation of extracellular signal-regulated kinase-1/2 signaling triggered by IL-6, as well as in a marked reduction in the proliferation, migration and morphogenic differentiation of endothelial cells. Interestingly, these polyphenols also modulated the expression of IL-6 signal transducing receptor (IL-6Rα) and the secretion of the extracellular matrix degrading enzyme MMP-2 as well as the expression of suppressor of cytokine signaling (SOCS3) protein.

However, there is growing evidence that certain practical nutritional measures have the potential to slow tumor angiogenesis, and it is reasonable to anticipate that, by combining several measures that work in distinct but complementary ways to impede the angiogenic process, a clinically useful 'multifocal angiostatic therapy' (MAT) might be devised. Several measures which might reasonably be included in such a protocol are discussed below, and include: a low-fat, low-glycemic index vegan diet, which may down-regulate the systemic IGF-I activity that supports angiogenesis; supplemental omega-3-rich fish oil, which has been shown to inhibit endothelial expression of Flk-1, a functionally crucial receptor for VEGF, and also can suppress tumor production of pro-angiogenic eicosanoids; high-dose selenium, which has recently been shown to inhibit tumor production of VEGF; green tea polyphenols, which can suppress endothelial responsiveness to both VEGF and fibroblast growth factor; and high-dose glycine, whose recently reported angiostatic activity may reflect inhibition of endothelial cell mitosis, possibly mediated by activation of glycine-gated chloride channels. In light of evidence that tumor-evoked angiogenesis has a high requirement for copper, copper depletion may have exceptional potential as an angiostatic measure, and is most efficiently achieved with the copper-chelating drug tetrathiomolybdate. If logistical difficulties make it difficult to acquire this experimental drug, high-dose zinc supplementation can achieve a slower depletion of the body's copper pool, and in any case can be used as maintenance therapy to maintain an adequate level of copper depletion. A provisional protocol is offered for a nutritionally based MAT entailing a vegan diet and supplemental intakes of fish oil, selenium, green tea polyphenols, glycine, and zinc. Inasmuch as cox-2 is overexpressed in many cancers, and cAMP can boost tumor production of various angiogenic factors as well as autogenous growth factors, adjunctive use of cox-2-specific NSAIDS may be warranted in some cases.", "title": "A wholly nutritional 'multifocal angiostatic therapy' for control of disseminated cancer." }, { "docid": "MED-3555", "text": "A number of epidemiological studies have investigated associations between various phytochemicals and cancer risk.

Although elevated risk of certain cancers with higher levels of certain phytochemicals was observed, an insufficient pool of studies examining the same associations or inconsistent findings across studies limit the ability to conclude that any one phytochemical increases cancer risk.

In industry, the principal use of hydrogen peroxide is as a bleaching agent in the manufacture of paper and pulp. Hydrogen peroxide has been employed medicinally for wound irrigation and for the sterilisation of ophthalmic and endoscopic instruments. Hydrogen peroxide causes toxicity via three main mechanisms: corrosive damage, oxygen gas formation and lipid peroxidation. Concentrated hydrogen peroxide is caustic and exposure may result in local tissue damage. Ingestion of concentrated (>35%) hydrogen peroxide can also result in the generation of substantial volumes of oxygen. Where the amount of oxygen evolved exceeds its maximum solubility in blood, venous or arterial gas embolism may occur. The mechanism of CNS damage is thought to be arterial gas embolisation with subsequent brain infarction. Rapid generation of oxygen in closed body cavities can also cause mechanical distension and there is potential for the rupture of the hollow viscus secondary to oxygen liberation. In addition, intravascular foaming following absorption can seriously impede right ventricular output and produce complete loss of cardiac output. Hydrogen peroxide can also exert a direct cytotoxic effect via lipid peroxidation. Ingestion of hydrogen peroxide may cause irritation of the gastrointestinal tract with nausea, vomiting, haematemesis and foaming at the mouth; the foam may obstruct the respiratory tract or result in pulmonary aspiration. Painful gastric distension and belching may be caused by the liberation of large volumes of oxygen in the stomach. Blistering of the mucosae and oropharyngeal burns are common following ingestion of concentrated solutions, and laryngospasm and haemorrhagic gastritis have been reported. Sinus tachycardia, lethargy, confusion, coma, convulsions, stridor, sub-epiglottic narrowing, apnoea, cyanosis and cardiorespiratory arrest may ensue within minutes of ingestion. Oxygen gas embolism may produce multiple cerebral infarctions. Although most inhalational exposures cause little more than coughing and transient dyspnoea, inhalation of highly concentrated solutions of hydrogen peroxide can cause severe irritation and inflammation of mucous membranes, with coughing and dyspnoea. Shock, coma and convulsions may ensue and pulmonary oedema may occur up to 24-72 hours post exposure. Severe toxicity has resulted from the use of hydrogen peroxide solutions to irrigate wounds within closed body cavities or under pressure as oxygen gas embolism has resulted. Inflammation, blistering and severe skin damage may follow dermal contact. Ocular exposure to 3% solutions may cause immediate stinging, irritation, lacrimation and blurred vision, but severe injury is unlikely. Exposure to more concentrated hydrogen peroxide solutions (>10%) may result in ulceration or perforation of the cornea. Gut decontamination is not indicated following ingestion, due to the rapid decomposition of hydrogen peroxide by catalase to oxygen and water. If gastric distension is painful, a gastric tube should be passed to release gas. Early aggressive airway management is critical in patients who have ingested concentrated hydrogen peroxide, as respiratory failure and arrest appear to be the proximate cause of death. Endoscopy should be considered if there is persistent vomiting, haematemesis, significant oral burns, severe abdominal pain, dysphagia or stridor. Corticosteroids in high dosage have been recommended if laryngeal and pulmonary oedema supervene, but their value is unproven. Endotracheal intubation, or rarely, tracheostomy may be required for life-threatening laryngeal oedema. Contaminated skin should be washed with copious amounts of water.

A telephone survey was administered to obtain information on demographic characteristics, dietary habits, dental visits, and knowledge of and presence of self-reported symptoms that can be related to dental erosion. Results A total of 520 participants were interviewed (response rate, 75%; sampling error, ± 4.4%) and their mean age was 37. Most respondents (79%) had ever had caries, and about two thirds (64%) attended dental check-ups at least once a year. Respondents had a mean of 5.4 meals per day and 36% had at least 6 meals per day. Fruit (89%) and lemon tea/water (41%) were the most commonly consumed acidic food and beverage. When asked if they ever noticed changes in their teeth, most respondents (92%) said they had experienced change that can be related to erosion. However, many (71%) had never heard about dental erosion and 53% mixed up dental erosion with dental caries. Conclusion Hong Kong Chinese adults have frequent intake of food and many have experienced symptoms that can be related to dental erosion.

We found that NF-kappaB was constitutively active in all human MM cell lines examined and that curcumin, a chemopreventive agent, down-regulated NF-kappaB in all cell lines as indicated by electrophoretic mobility gel shift assay and prevented the nuclear retention of p65 as shown by immunocytochemistry. All MM cell lines showed consitutively active IkappaB kinase (IKK) and IkappaBalpha phosphorylation. Curcumin suppressed the constitutive IkappaBalpha phosphorylation through the inhibition of IKK activity. Curcumin also down-regulated the expression of NF-kappaB-regulated gene products, including IkappaBalpha, Bcl-2, Bcl-x(L), cyclin D1, and interleukin-6. This led to the suppression of proliferation and arrest of cells at the G(1)/S phase of the cell cycle. Suppression of NF-kappaB complex by IKKgamma/NF-kappaB essential modulator-binding domain peptide also suppressed the proliferation of MM cells. Curcumin also activated caspase-7 and caspase-9 and induced polyadenosine-5'-diphosphate-ribose polymerase (PARP) cleavage. Curcumin-induced down-regulation of NF-kappaB, a factor that has been implicated in chemoresistance, also induced chemosensitivity to vincristine and melphalan.

It can be inhaled and absorbed through the skin and mucous membranes. The most toxic forms of mercury are its organic compounds such as dimethylmercury and methylmercury.

Methylmercury is produced by microbial methylation of inorganic mercury in water sediment then it infiltrates the food chain and it consequently accumulates in fish. Fish are the main source of methylmercury in human food. Mercury is transferred into a hair; and this can be than used to monitor the long-term exposure to mercury. The content of mercury in hair depends on the frequency of fish consumption. The aim of our study was to compare mercury content in the hair of children that had various amounts of fish consumption (increased or reduced). DESIGN: Total mercury content in hair was determined by direct method of cold vapors using an AMA 245 analyzer. A total of 174 hair samples from the children (9-17 years old) were analyzed.

[ { "docid": "MED-3090", "text": "Background Hyperphosphatemia has been identified in the past decade as a strong predictor of mortality in advanced chronic kidney disease (CKD). For example, a study of patients in stage CKD 5 (with an annual mortality of about 20%) revealed that 12% of all deaths in this group were attributable to an elevated serum phosphate concentration. Recently, a high-normal serum phosphate concentration has also been found to be an independent predictor of cardiovascular events and mortality in the general population. Therefore, phosphate additives in food are a matter of concern, and their potential impact on health may well have been underappreciated. Methods We reviewed pertinent literature retrieved by a selective search of the PubMed and EU databases (www.zusatzstoffe-online.de, www.codexalimentarius.de), with the search terms “phosphate additives” and “hyperphosphatemia.” Results There is no need to lower the content of natural phosphate, i.e. organic esters, in food, because this type of phosphate is incompletely absorbed; restricting its intake might even lead to protein malnutrition. On the other hand, inorganic phosphate in food additives is effectively absorbed and can measurably elevate the serum phosphate concentration in patients with advanced CKD. Foods with added phosphate tend to be eaten by persons at the lower end of the socioeconomic scale, who consume more processed and “fast” food. The main pathophysiological effect of phosphate is vascular damage, e.g. endothelial dysfunction and vascular calcification. Aside from the quality of phosphate in the diet (which also requires attention), the quantity of phosphate consumed by patients with advanced renal failure should not exceed 1000 mg per day, according to the guidelines. Conclusion Prospective controlled trials are currently unavailable. In view of the high prevalence of CKD and the potential harm caused by phosphate additives to food, the public should be informed that added phosphate is damaging to health.

Phage therapy was performed on human subjects in the United States, Europe and Asia in the few decades following their discovery. However, Western countries largely abandoned PT in favour of antibiotics in the 1940s. The relatively recent renaissance of PT in the West can be attributed partly to the increasing prevalence of antibiotic resistance in human and animal pathogens. However, the stringent controls on human trials now required in the United States and Europe have led to a greater number of domestic animal and agricultural applications as an alternative to PT in man. This trend is set to continue, at least in the short term, with recent approval from the Food and Drug Administration allowing commercial phage treatments to be used in human food in the USA. Nevertheless, despite these significant milestones and the growing number of successful PT trials, significant obstacles remain to their widespread use in animals, food and ultimately medicine in many parts of the world.

SETTING: We measured the phosphorus content of 44 food products, including 30 refrigerated or frozen precooked meat, poultry, and fish items, generally national brands. OUTCOMES: Measured and reported phosphorus content of foods. MEASUREMENTS: Phosphorus by using Association of Analytical Communities official method 984.27; protein by using Association of Analytical Communities official method 990.03. RESULTS: We found that the ratio of phosphorus to protein content in these items ranged from 6.1 to 21.5 mg of phosphorus per 1 g of protein. The mean ratio in the 19 food products with a label listing phosphorus as an additive was 14.6 mg/g compared with 9.0 mg/g in the 11 items without listed phosphorus. The phosphorus content of only 1 precooked food product was available in a widely used dietary database. LIMITATIONS: Results cannot be extrapolated to other products. Manufacturers also may alter the phosphorus content of foods at any time. Protein content was not directly measured for all foods.

This report summarizes 2010 surveillance data and describes trends since 1996. RESULTS: A total of 19,089 infections, 4,247 hospitalizations, and 68 deaths were reported from FoodNet sites in 2010. Salmonella infection was the most common infection reported (17.6 illnesses per 100,000 persons) and was associated with the largest number of hospitalizations (2,290) and deaths (29); no significant change in incidence of Salmonella infection has occurred since the start of surveillance during 1996-1998. Shiga toxin-producing Escherichia coli (STEC) O157 infection caused 0.9 illnesses per 100,000. Compared with 1996-1998, overall incidence of infection with six key pathogens in 2010 was 23% lower, and pathogen-specific incidence was lower for Campylobacter, Listeria, STEC O157, Shigella, and Yersinia infection but higher for Vibrio infection. Compared with a more recent period, 2006--2008, incidence in 2010 was lower for STEC O157 and Shigella infection but higher for Vibrio infection. CONCLUSIONS: The incidence of STEC O157 infection has declined to reach the 2010 national health objective target of ≥1 case per 100,000. This success, as well as marked declines since 1996-1998 in overall incidence of six key foodborne infections, demonstrates the feasibility of preventing foodborne illnesses. IMPLICATIONS FOR PUBLIC HEALTH PRACTICE: Salmonella infection should be targeted because it has not declined significantly in more than a decade, and other data indicate that it is one of the most common foodborne infections, resulting in an estimated $365 million in direct medical costs annually. The prevention measures that reduced STEC O157 infection need to be applied more broadly to reduce Salmonella and other infections.

Omnivorous diets low in EPA and DHA are linked to impaired mood states in observational and experimental studies. Methods We examined associations between mood state and polyunsaturated fatty acid intake as a result of adherence to a vegetarian or omnivorous diet in a cross-sectional study of 138 healthy Seventh Day Adventist men and women residing in the Southwest. Participants completed a quantitative food frequency questionnaire, Depression Anxiety Stress Scale (DASS), and Profile of Mood States (POMS) questionnaires. Results Vegetarians (VEG:n = 60) reported significantly less negative emotion than omnivores (OMN:n = 78) as measured by both mean total DASS and POMS scores (8.32 ± 0.88 vs 17.51 ± 1.88, p = .000 and 0.10 ± 1.99 vs 15.33 ± 3.10, p = .007, respectively). VEG reported significantly lower mean intakes of EPA (p < .001), DHA (p < .001), as well as the omega-6 fatty acid, arachidonic acid (AA; p < .001), and reported higher mean intakes of shorter-chain α-linolenic acid (p < .001) and linoleic acid (p < .001) than OMN.

Therefore, we evaluated the effects of comprehensive lifestyle changes on prostate specific antigen (PSA), treatment trends and serum stimulated LNCaP cell growth in men with early, biopsy proven prostate cancer after 1 year. MATERIALS AND METHODS: Patient recruitment was limited to men who had chosen not to undergo any conventional treatment, which provided an unusual opportunity to have a nonintervention randomized control group to avoid the confounding effects of interventions such as radiation, surgery or androgen deprivation therapy. A total of 93 volunteers with serum PSA 4 to 10 ng/ml and cancer Gleason scores less than 7 were randomly assigned to an experimental group that was asked to make comprehensive lifestyle changes or to a usual care control group. RESULTS: None of the experimental group patients but 6 control patients underwent conventional treatment due to an increase in PSA and/or progression of disease on magnetic resonance imaging. PSA decreased 4% in the experimental group but increased 6% in the control group (p = 0.016). The growth of LNCaP prostate cancer cells (American Type Culture Collection, Manassas, Virginia) was inhibited almost 8 times more by serum from the experimental than from the control group (70% vs 9%, p <0.001).

To assess the direct effect of postprandial triglyceride-rich lipoproteins on endothelial function, an early factor in atherogenesis--10 healthy, normocholesterolemic volunteers--were studied before and for 6 hours after single isocaloric high- and low-fat meals (900 calorie; 50 and 0 g fat, respectively). Endothelial function, in the form of flow-mediated vasoactivity, was assessed in the brachial artery using 7.5-MHz ultrasound as percent arterial diameter change 1 minute after 5 minutes of upper-arm arterial occlusion.

Serum triglycerides increased from 94 +/- 55 mg/dl preprandially to 147 +/- 80 mg/dl 2 hours after the high-fat meal (p = 0.05). Flow-dependent vasoactivity decreased from 21 +/- 5% preprandially to 11 +/- 4%, 11 +/- 6%, and 10 +/- 3% at 2, 3, and 4 hours after the high-fat meal, respectively (all p <0.05 compared with low-fat meal data).

Depressive symptoms were assessed using the Center for Epidemiologic Studies Depression (CES-D) Scale. Dietary patterns were derived by using principal component analysis of the consumption of 52 food and beverage items, which was assessed by a validated brief diet history questionnaire.

The burden of non-communicable diseases (NCDs) is increasing rapidly in the developing world, very much as a result of changes in lifestyles. In addition to changes in tobacco use and physical activity, major changes are taking place in diets, contributing greatly to the growing epidemic of NCD. Thus, a huge global public health challenge is how to influence the trends in diet and nutrition for effective global NCD prevention. The health transition took place rapidly in Finland after World War II and mortality from cardiovascular disease (CVD) was exceptionally high. The North Karelia Project was launched in 1972 as a community-based, and later as a national, programme to influence diet and other lifestyles that are crucial in the prevention of CVD. The intervention had a strong theory base and it employed comprehensive strategies. Broad community organisation and the strong participation of people were the key elements. Evaluation has shown how the diet (particularly fat consumption) has changed and how these changes have led to a major reduction in population serum cholesterol and blood pressure levels. It has also shown how ischaemic heart disease mortality in a working-age population has declined by 73% in North Karelia and by 65% in the whole country from 1971 to 1995. Although Finland is an industrialised country, North Karelia was rural, of rather low socio-economic level and with many social problems in the 1970s and 1980s. The project was based on low-cost intervention activities, where people's participation and community organisations played a key role. Comprehensive interventions in the community were eventually supported by national activities--from expert guidelines and media activities to industry collaboration and policy. Similar principles for nutrition intervention programmes could be used in developing countries, obviously tailored to the local conditions.

Results Of 38 chicken products, 35 (92%) had phosphorus containing additives listed among their ingredients. For every category of chicken products containing additives, the actual phosphorus content was greater than the content expected from nutrient database.

However, genetic techniques to more accurately characterize Escherichia coli strains have not been exploited. MATERIALS AND METHODS: A total of 2,700 E. coli colonies isolated from the urine and rectal swabs of 9 female subjects with acute uncomplicated cystitis and from the rectal swabs of 30 healthy women were serotyped and examined for genes encoding various urovirulence factors by colony hybridization test. The clonality of the urine and fecal isolates of E. coli from the cystitis subjects was further evaluated by pulsed-field gel electrophoresis (PFGE). RESULTS: E. coli strains causing cystitis dominated the rectal flora of 7 of 9 patients. In the remaining 2 patients, similar clones comprised at least 20% of the fecal flora. Carriage of E. coli strains with a variety of urovirulence factors was quite common among healthy women. PFGE demonstrated that most of the isolates sharing the same serotypic characteristics and virulence factors in the urine and rectal swab samples from each subject were identical. CONCLUSIONS: Based upon precise genetic techniques, our results clearly support the fecal-perineal-urethral hypothesis, indicating that E. coli strains residing in the rectal flora serve as a reservoir for urinary tract infections, e.g., cystitis.", "title": "Genetic evidence supporting the fecal-perineal-urethral hypothesis in cystitis caused by Escherichia coli." }, { "docid": "MED-5334", "text": "Until recently, intact protein that is rich in tryptophan was not seen as an alternative to pharmaceutical-grade tryptophan because protein also contains large neutral amino acids (LNAAs) that compete for transport sites across the blood-brain barrier.

Restriction of dietary phosphorus is necessary to control for phosphate balance during both conservative therapy and dialysis treatment. The extra amount of phosphorus which is consumed as a result of phosphate-containing food additives is a real challenge for patients with renal disease and for dieticians because it represents a \"hidden\" phosphate load. The objective of this study was to measure phosphorus content in foods, common protein sources in particular, and comprised both those which included a listing of phosphate additives and those which did not. METHODS: Determinations of dry matter, nitrogen, total and soluble phosphate ions were carried out in 60 samples of foods, namely cooked ham, roast breast turkey, and roast breast chicken, of which, 30 were with declared phosphate additives and the other 30 similar items were without additives. RESULTS: Total phosphorus (290 ± 40 mg/100 g vs. 185 ± 23 mg/100 g, P < .001) and soluble phosphorus (164 ± 25 mg/100 g vs. 100 ± 19 mg/100 g, P < .001) content were higher in products containing additives than in foods without additives. No difference was detected between the 2 groups regarding dry matter (27.2 ± 2.0 g/100 g vs. 26.7 ± 1.9 g/100 g) or total nitrogen (3.15 ± 0.40 g/100 g vs. 3.19 ± 0.40 g/100 g). Consequently, phosphorus intake per gram of protein was much greater in the foods containing phosphorus additives (15.0 ± 3.1 mg/g vs. 9.3 ± 0.7 mg/g, P < .001). CONCLUSIONS: Our results show that those foods which contain phosphate additives have a phosphorus content nearly 70% higher than the samples which did not contain additives. This creates a special concern because this extra amount of phosphorus is almost completely absorbed by the intestinal tract. These hidden phosphates worsen phosphate balance control and increase the need for phosphate binders and related costs. Information and educational programs are essential to make patients with renal disease aware of the existence of foods with phosphate additives. Moreover, these facts highlight the need for national and international authorities to devote more attention to food labels which should clearly report the amount of natural or added phosphorus.

Although salmonellosis is usually self-limiting, severe infections typically require antimicrobial treatment, and ceftriaxone, an extended-spectrum cephalosporin (ESC), is commonly used in both adults and children. Surveillance conducted by the National Antimicrobial Resistance Monitoring System (NARMS) has shown a recent increase in ESC resistance among Salmonella Heidelberg isolated from food animals at slaughter, retail meat, and humans. ESC resistance among Salmonella in the United States is usually mediated by a plasmid-encoded bla(CMY) β-lactamase. In 2009, we identified 47 ESC-resistant bla(CMY)-positive Heidelberg isolates from humans (n=18), food animals at slaughter (n=16), and retail meats (n=13) associated with a spike in the prevalence of this serovar. Almost 90% (26/29) of the animal and meat isolates were isolated from chicken carcasses or retail chicken meat. We screened NARMS isolates for the presence of bla(CMY), determined whether the gene was plasmid-encoded, examined pulsed-field gel electrophoresis patterns to assess the genetic diversities of the isolates, and categorized the bla(CMY) plasmids by plasmid incompatibility groups and plasmid multi-locus sequence typing (pMLST). All 47 bla(CMY) genes were found to be plasmid encoded. Incompatibility/replicon typing demonstrated that 41 were IncI1 plasmids, 40 of which only conferred bla(CMY)-associated resistance. Six were IncA/C plasmids that carried additional resistance genes. pMLST of the IncI1-bla(CMY) plasmids showed that 27 (65.8%) were sequence type (ST) 12, the most common ST among bla(CMY)-IncI1 plasmids from Heidelberg isolated from humans. Ten plasmids had a new ST profile, ST66, a type very similar to ST12.

Due to the relatively high level of PCDDs and PCDFs commonly found in human breast milk from American women and from women in other industrial countries, a nursing infant may consume an average of 35-53 pg TEq/kg body weight/day in its first year of life. This may be compared with the current U.S. EPA virtually safe dose of 0.006 pg TCDD/kg body weight per day over a 70-year lifetime based on an upper limit cancer risk of 10(-6), or the 10 pg/kg/day used by some European government agencies.", "title": "Congener-specific levels of dioxins and dibenzofurans in U.S. food and estimated daily dioxin toxic equivalent intake." }, { "docid": "MED-335", "text": "OBJECTIVE: Meat and milk products are important sources of dietary phosphorus (P) and protein. The use of P additives is common both in processed cheese and meat products. Measurement of in vitro digestible phosphorus (DP) content of foods may reflect absorbability of P. The objective of this study was to measure both total phosphorus (TP) and DP contents of selected meat and milk products and to compare amounts of TP and DP and the proportion of DP to TP among different foods. METHODS: TP and DP contents of 21 meat and milk products were measured by inductively coupled plasma optical emission spectrometry (ICP-OES). In DP analysis, samples were digested enzymatically, in principle, in the same way as in the alimentary canal before the analyses. The most popular national brands of meat and milk products were chosen for analysis. RESULTS: The highest TP and DP contents were found in processed and hard cheeses; the lowest, in milk and cottage cheese. TP and DP contents in sausages and cold cuts were lower than those in cheeses. Chicken, pork, beef, and rainbow trout contained similar amounts of TP, but slightly more variation was found in their DP contents. CONCLUSIONS: Foods containing P additives have a high content of DP. Our study confirms that cottage cheese and unenhanced meats are better choices than processed or hard cheeses, sausages, and cold cuts for chronic kidney disease patients, based on their lower P-to-protein ratios and sodium contents. The results support previous findings of better P absorbability in foods of animal origin than in, for example, legumes. Copyright © 2012 National Kidney Foundation, Inc. Published by Elsevier Inc.

We examined dietary determinants of adiposity in an elderly Mediterranean population with customarily high nut consumption. METHODS AND RESULTS: A cross-sectional study was conducted in 847 subjects (56% women, mean age 67 years, BMI 29.7kg/m(2)) at high cardiovascular risk recruited into the PREDIMED study. Food consumption was evaluated by a validated semi-quantitative questionnaire, energy expenditure in physical activity by the Minnesota Leisure Time Activity questionnaire, and anthropometric variables by standard measurements. Nut intake decreased across quintiles of both BMI and waist circumference (P-trend <0.005; both). Alcohol ingestion was inversely related to BMI (P-trend=0.020) and directly to waist (P-trend=0.011), while meat intake was directly associated with waist circumference (P-trend=0.018). In fully adjusted multivariable models, independent dietary associations of BMI were the intake of nuts inversely (P=0.002) and that of meat and meat products directly (P=0.042). For waist circumference, independent dietary associations were intake of nuts (P=0.002) and vegetables (P=0.040), both inversely, and intake of meat and meat products directly (P=0.009). From the regression coefficients, it was predicted that BMI and waist circumference decreased by 0.78kg/m(2) and 2.1cm, respectively, for each serving of 30g of nuts.

Western nutrition is characterized by high calorie uptake, high glycemic load, high fat and meat intake, as well as increased consumption of insulin- and IGF-1-level elevating dairy proteins. Metabolic signals of Western diet are sensed by the nutrient-sensitive kinase, mammalian target of rapamycin complex 1 (mTORC1), which integrates signals of cellular energy, growth factors (insulin, IGF-1) and protein-derived signals, predominantly leucine, provided in high amounts by milk proteins and meat. mTORC1 activates SREBP, the master transcription factor of lipogenesis. Leucine stimulates mTORC1-SREBP signaling and leucine is directly converted by sebocytes into fatty acids and sterols for sebaceous lipid synthesis. Over-activated mTORC1 increases androgen hormone secretion and most likely amplifies androgen-driven mTORC1 signaling of sebaceous follicles. Testosterone directly activates mTORC1. Future research should investigate the effects of isotretinoin on sebocyte mTORC1 activity. It is conceivable that isotretinoin may downregulate mTORC1 in sebocytes by upregulation of nuclear levels of FoxO1. The role of Western diet in acne can only be fully appreciated when all stimulatory inputs for maximal mTORC1 activation, i.e., glucose, insulin, IGF-1 and leucine, are adequately considered. Epidemic acne has to be recognized as an mTORC1-driven disease of civilization like obesity, type 2 diabetes, cancer and neurodegenerative diseases. These new insights into Western diet-mediated mTORC1-hyperactivity provide a rational basis for dietary intervention in acne by attenuating mTORC1 signaling by reducing (1) total energy intake, (2) hyperglycemic carbohydrates, (3) insulinotropic dairy proteins and (4) leucine-rich meat and dairy proteins. The necessary dietary changes are opposed to the evolution of industrialized food and fast food distribution of Westernized countries. An attenuation of mTORC1 signaling is only possible by increasing the consumption of vegetables and fruit, the major components of vegan or Paleolithic diets. The dermatologist bears a tremendous responsibility for his young acne patients who should be advised to modify their dietary habits in order to reduce activating stimuli of mTORC1, not only to improve acne but to prevent the harmful and expensive march to other mTORC1-related chronic diseases later in life.", "title": "Dietary intervention in acne" }, { "docid": "MED-2249", "text": "High-level cadmium (Cd) exposure has long been known to induce nephropathy, severe osteoporosis, and fractures in humans. More recent epidemiology, however, reveals that, in populations not known to have important industrial exposure to this heavy metal, high-normal blood or urine Cd levels correlate with increased risk for vascular disorders, cancers, diabetes, and total mortality, as well as osteoporosis and nephropathy. Since these disorders appear unlikely to expedite Cd absorption, and since Cd has promoted these pathologies in rodent studies, it seems reasonable to conclude that Cd is an important mediating risk factor for these disorders in humans. Avoiding tobacco smoke or frequent ingestion of shellfish or organ meats can lessen humans exposure to Cd, but the chief dietary sources of Cd are plant-derived foods - green leafy vegetables, whole grains, tubers, and root vegetables - typically recommended for their health-supportive properties; indeed, among non-smokers, vegans tend to have the highest Cd body burden. Fortunately, iron sufficiency and ample dietary intakes of calcium, magnesium, and zinc can impede absorption of dietary Cd, both by down-regulating intestinal expression of mineral transporters, and by directly competing with Cd for access to these transporters. Correction of iron deficiency appears to be of particular importance for controlling Cd absorption. Moreover, zinc supplementation can counteract the toxicity of Cd already in the body via induction of metallothionein, which binds Cd avidly via its sulfhydryl groups; so long as it remains sequestered in this form, Cd is innocuous. Zinc supplementation may in any case be recommendable, as optimal zinc status exerts protective anti-inflammatory, antioxidant, and immunosupportive effects. Inasmuch as the toxicity of Cd appears to be mediated in large part by oxidative stress, ingestion of spirulina, lipoic acid, melatonin, and N-acetylcysteine may also have potential for mitigating the risk associated with Cd exposure, as suggested by rodent studies. Hence, although Cd may prove to be a major risk factor for morbidity and mortality in humans, practical strategies for limiting its absorption and pathogenic impact are at hand.

SETTING: Shohada Teaching Hospital, Tehran, Iran. SUBJECTS: Overall, 100 female patients aged 30-65 years with breast cancer and 174 female hospital controls were included in the present study. Dietary intake was assessed using a valid and reliable semi-quantitative FFQ consisting of 168 food items. RESULTS: Two dietary patterns were identified explaining 24·31 % of dietary variation in the study population. The 'healthy' food pattern was characterized by the consumption of vegetables, fruits, low-fat dairy products, legumes, olive and vegetable oils, fish, condiments, organ meat, poultry, pickles, soya and whole grains; while the 'unhealthy' food pattern was characterized by the consumption of soft drinks, sugars, tea and coffee, French fries and potato chips, salt, sweets and desserts, hydrogenated fats, nuts, industrial juice, refined grains, and red and processed meat.

We have shown that PhIP is also potently estrogenic and have proposed that this hormonal activity contributes to its target site carcinogenicity. We now postulate that the estrogenic properties of PhIP influence metastatic potential. We have used an in vitro assay for cell invasion based upon digestion and migration through a reconstituted basement membrane model. Zymography and immunoblotting were used to confirm PhIP-mediated changes associated with induction of the invasive phenotype. Treatment of the mammary cancer cell lines MCF-7 and T47D with PhIP induces cells to digest and migrate through a reconstituted basement membrane.

METHODS: Standardized mortality ratios (SMRs) and proportional mortality ratios (PMRs) were estimated for each cohort as a whole and in subgroups defined by race and sex, using the US general population mortality rates for comparison. Study subjects were followed up from January 1950 to December 2006, during which time over 60% of them died. RESULTS: An excess of deaths from cancers of the base of the tongue, esophagus, lung, skin, bone and bladder, lymphoid leukemia, and benign tumors of the thyroid and other endocrine glands, and possibly Hodgkin's disease, was observed in abattoir and meat processing workers.

I have no idea about India's regulatory environment. You are opening yourself up to massive liabilities and problems if you deposit their money in your account. I managed investment accounts as a private investment advisor for years (those with less than 15 clients were not required to register) until Dodd-Frank changed the rules. Thus you would have to register as an advisor, probably needing to take the series 65 exam (or qualifying some other way, e.g. getting your CFP/CFA/etc...). I used a discount broker/dealer (Scottrade) as the custodian. Here's how it works: Each client's account was their own account, and I had a master account that allowed me to bill their accounts and manage them. They signed paperwork making me the advisor on their account. I had very little accounting to handle (aside from tracking basis for taxed accounts). If you take custody of the money, you'll have regulatory obligations. There are always lots of stories in the financial advisor trade publications about advisors who go to jail for screwing their clients. The most common factor: they took custody of the assets. I understand why you want a single account - you want to ensure that each client gets the same results, right? Does each client want the same results? Certainly the tax situation for each is different, yes? Perhaps one has gains and wants to take losses in one year, and the other doesn't. If their accounts are managed separately, one can take losses while the other realizes gains to offset other losses. Financial advisors offer these kinds of accounts as Separately Managed Accounts (SMAs). The advisors on these kinds of accounts are mutual funds managers, and they try to match a target portfolio, but they can do things like realize gains or losses for clients if their tax situation would prefer it. You certainly can't let them put retirement accounts into your single account unless the IRS has you on their list of acceptable custodians. I suggest that you familiarize yourself thoroughly with the regulatory environment that you want to operate under. Then, after examining the pros and cons, you should decide which route you want to take. I think the most direct and feasible route is to pass the Series 65, register as an investment advisor, and find a custodian who will let you manage the assets as the advisor on the account. Real estate is another matter, you should talk to an attorney, not some random guy on the internet (even if he has an MBA and a BS in Real Estate, which I do).

First log into the website for the HSA and see if you have money left. This can be important because if there is still money left they might be charging you a monthly fee. You should have gotten a letter from the old company or the administrator when you left the High deductible insurance plan. This would have told you your options regarding the spending or transferring of old funds. HSA related numbers would have appeared on your W2, and you should have a 1099-SA from the administrator. It is likely that there is a copy of the 1099 on the administrators website. The numbers you enter on the tax forms depends on how much you contributed from your paycheck, how much your company contributed, and how much you sent (if any) from other sources besides payroll deduction. You will also have to know how much money was withdrawn from the HSA and how much was used for medical purposes. The last month rule is for those people who start in the middle of the year. If you start partway through the year you are allowed to make the maximum contribution if you still have it at the end of the year, and you expect to keep it. The Last Month Rule The Last Month Rule states that if you are covered by an HSA eligible health plan on the first day of the last month of a given year, you are considered an eligible individual for the entire year. In turn, you can then contribute to the HSA for that full year. If you are covered by an HDHP on Dec 1st of a given year, you may contribute the maximum for that year. For example, you could begin coverage and open up my HSA in November of a given year. Come December 1st, you are covered and per the Last Month Rule, considered an eligible employee for that full year. That allows you to contribute up to that year’s contribution limit, even waiting a few months to make a prior year contribution if you like. Back up the truck and load up the HSA! However, there is a catch. The Testing Period The Testing Period states if you use the Last Month Rule, you must remain an eligible individual (covered by HDHP) for the following 12 months. If you fail to remain an eligible individual (change insurance plans, lose insurance plan, receive other health coverage) any “extra” contributions you made as a result of the Last Month Rule will be taxed and penalized. If you contribute per the Last Month Rule and end your HDHP insurance within 1 year, you will have to pay tax on any excess contributions you were allowed to make and pay a 10% penalty.

The deductible can trip some people up, because if they put too much into the limited purpose FSA and don't hit the deductible for the regular insurance policy, they can't get to all the money in the FSA. Because you have the ability to spend the potential money in the FSA before all the money has been contributed, it can allow you to make that payment for the braces in January. I did this the first year we had the HSA. I knew I needed to pay a dental bill early in the year. But the HSA would only have a few hundred dollars at that time, so I used the limited purpose FSA to be able to make that payment. This could also work if you spent a lot of money in the previous year. Because you have the ability to adjust how much money goes into the HSA each each pay period, this idea does keep the option open to fully fund the HSA if your finances improve. Regarding the deductible. The law limits what you can use the limited purpose FSA for: dental and vision only. There is an exception. If you hit the deductible for the high deductible insurance policy, then you can use the funds in the limited purpose FSA for ANY medical reason. When I did this a few years ago, I needed to send extensive paperwork to the company holding the funds before they would release the funds for dental. Once I sent them proof that I had met the deductible, then any medical expense after that date could use the FSA with minimal paperwork. If you fully fund the FSA beyond the cost of the braces, and then have a light year medical expense wise, you might not be able to spend all money in the FSA by the deadline. Regarding state taxes.

This seemed to be overkill. It would be overkill if you're taking distributions regularly and you have enough valid (and otherwise unreimbursed) medical receipts each year to correspond to your distributions. However, if you are pumping money into the HSA without regular distributions, then you may need to keep receipts for a long time, possibly since the beginning of your HSA. For example: If the IRS was to audit my HSA deductions would the Aetna online claims be adequate? It's better than nothing, but it is not ideal. You need to provide proof of what you actually paid, not just what was billed. (How would the IRS know if you actually paid the bill?) So, the bill and receipt together would be preferred. Also, there are many eligible expenses for HSA that would not be covered by your health insurance and would not appear in your Aetna statements (dental work for example). Personally I have an excel spreadsheet with every eligible expense listed, every contribution and distribution I make, and a box of receipts since I opened the HSA account. Should I also archive screenshots of these claims digitally somewhere? If you have the time and diligence to do it, then it wouldn't hurt. I personally am only one house fire away from having to make a lot of phone calls if I wanted to re-build my receipts folder from scratch. I actually have \"\"scan my HSA receipts\"\" on my todo list (where's it been for years as a pretty low priority). Lastly it makes sense to spend the money in my HSA on anything eligible because you can never roll it over into a retirement account, its shaky if another person (spouse) could get reimbursed for eligible medical expenses if you die, and if you lose your receipts you may not be able to spend all of the HSA money tax free. Is this an accurate assessment or is there a reason why I should not touch the HSA money at all and wait to reimburse my eligible expenses. First off, if you are married the HSA can be transferred to your spouse. But in general, it really depends on what you would do with the money if you distributed it right away. If you need the money to pay debts, bills, etc, then it might make sense to take it, but if it would be extra money that you would invest somewhere, then you should leave it in the HSA because it grows tax free while it's in there and (probably) wouldn't if you take it out. The caveat though is that you need to find an HSA administrator that offers your preferred investment choices. As for your worry that you might lose your receipts, well, that's a valid point- but I wouldn't drive my decision based on that- I would archive them digitally to remove that concern completely. ...Should I reimburse myself from ... the HSA funds if I am not hitting the 401k limit yet? It depends. If it's a Roth 401k, all other things being equal, (you are able to choose the same investments with your HSA as you can choose in your 401K, and the costs are the same), then you are better off leaving the money in your HSA rather than pulling it out and putting it into the Roth 401k. The reason is that there is no tax difference, and once you put it into the 401K you (probably) can't touch it (for free) until you retire. With the HSA, if you could have taken a distribution but chose not to, then you can take that amount of money out anytime you want to without any consequences, just like your normal checking account. However, if you have a traditional 401k, and if taking HSA distributions would increase your cash flow such that you could afford to contribute more to the 401k, then this would lower your tax burden that year by reducing your taxable income.\"", "title": "" }, { "docid": "155847", "text": "\"First, your employee needs to work out his contribution limit for the year.

However, I did want to point out another pro - HSAs are (or can be) easy to manage. You said: Is this a better way to approach health care costs instead of itemizing health care expenses on yearly federal taxes? I'm not sure which company you are looking at establishing your HSA with, but with mine I have a debit card that I use when paying for medical care and then at the end of the year I get a 1099-SA that provides the amount of money spent on qualified purchases that calendar year. Yes, there are a few extra boxes I need to fill in for my 1040 come tax time, but I don't need to itemize my healthcare costs over the year. It really is pretty simple and straightforward. Also, one con that is worth noting is that you become much more sensitive to healthcare costs due to the high deductible healthcare plan an HSA requires. For example, in all the years we've had an HSA we've not yet met our deductible, which means we pay out of pocket for any non-routine doctor visits. (The health insurer pays 100% of routine visits, like my wife's annual, well-baby check ups for the little one, and so on.) So, when you're feeling really sick and think a doctor's visit would be warranted, you have to make a decision: After being faced with this decision a time or two you will start to envy those who have just a $20 copay! Of course, that's just an emotional con. Each year I run the numbers on how much we spent per year on out of pocket plus premiums and compare it to what it would cost in premiums for an HMO-type plan, and the HSA plan always comes ahead. (In part because we are a pretty healthy family and I work for myself so do not get to enjoy group discount rates.)

Now, they are not foolproof; legally, you can withdraw money if it is spent on the child's behalf, so that can be gamed. What you can do to protect against that is to make another person the custodian (or, perhaps make them joint custodians with yourself, requiring both signatures for withdrawals). UTMA/UGMA accounts do not have to be bank savings accounts; for example, both of my children have accounts at Vanguard which are effectively their college savings accounts. They're invested in various ETFs and similar kinds of investments; you're welcome to choose from a wide variety of options depending on risk tolerance. Typically these accounts have relatively small fees, particularly if you have a reasonable minimum balance (I think USD$10k is a common minimum for avoiding larger fees). If you are looking for something even more secure than a UGMA or UTMA account, you can set up a trust. These have several major differences over the UGMA/UTMA accounts: Some of course consider the second point an advantage, some a disadvantage - we (and Grandma) prefer to let our children make their own choices re: college, while others may not prefer that. Also worth noting as a difference - and concern to think about - in these two. A UGMA or UTMA account that generates income may have taxable events - interest or dividend income.

For those who would like to remain as one, that is fine. But for those who spent time and money to study and know how to invest, I don't think the plan manager can limit the participants ability to manage their own portfolio especially if the funds have no matching from the employer like mine. All I can say to all who have IRA or any retirement accounts, educate yourself early because if you leave it all to your portfolio managers, you lost a lot. Don't believe much in what those commercial fund managers also show in their presentation just to move your funds for them to manage. Be proactive.

So there's an incentive to withdraw your money and spend it now. If, say, I'm planning to buy a car, and my savings are declining in real value, then if I buy a car today I can get a better car than if I wait until tomorrow. When interest rates are high compared to inflation, the reverse is true. My savings are increasing in value, so the longer I leave my money in the bank the more it's worth. If I wait until tomorrow to buy a car I can get a better car than I would be able to buy today. Also, people find alternative places to keep their savings. If a savings account will result in me losing value every day my money is there, then maybe I'll put the money in the stock market or buy gold or whatever. So for the banks to continue to get enough money to make loans, they have to increase the interest rates they pay to lure customers back to the bank. There is no reason per se for rising interest rates to consumers to directly cause an increase in the inflation rate. Inflation is caused by the money supply growing faster than the amount of goods and services produced. Interest rates are a cost. If interest rates go up, people will borrow less money and spend it on other things, but that has no direct effect on the total money supply. Except ... you may note I put a bunch of qualifiers in that paragraph. In the United States, the Federal Reserve loans money to banks. It creates this money out of thin air. So when the interest that the Federal Reserve charges to the banks is low, the banks will borrow more from the Feds. As this money is created on the spot, this adds to the money supply, and thus contributes to inflation. So if interest rates to consumers are low, this encourages people to borrow more money from the banks, which encourages the banks to borrow more from the Feds, which increases the money supply, which increases inflation.

Your country may have similar regional rules. Also - each country has accounts specifically geared toward retirement, with different favorable rules regarding taxation. In the US, we have accounts that can be funded at any age, so long as there's earned income. My daughter started one of these accounts when she started baby sitting at age 12.

In the modern era we have things like the Consumer Price Index (CPI) in the United States, where the Bureau of Labor Statistics literally sends \"\"shoppers\"\" out to find prices of things and surveys people to find out what they buy. This results in a variety of \"\"indexes\"\" which variously get reported by media outlets as \"\"inflation\"\" (or \"\"deflation\"\" if the change in value goes the other way). There are also other measurements available like the MIT Billion Prices Project which attempt to make their own reading of the \"\"worth\"\" of currencies.

The limit is for everything contributed to the HSA, whether it is an employer contribution or an account holder contribution.

Some funds you could look at (just examples, not recommendations) might include several PIMCO funds including their commodity real return and all-asset; Hussman Strategic Total Return; diversified commodities index ETFs; stuff like that has a lot of the theoretical benefits of gold but isn't as dependent on gold specifically.

(Look, I said let's pretend.) You want to invest $1,000. For the time being, let's also pretend that your purchasing 0.01% of all the stock won't affect prices anywhere. One company splits the index into 10,000 parts worth $1,000 each. The other splits the same index into 10,000,000 parts worth $1 each. Both track the underlying index perfectly. If you invest $1,000 with the first company, you get one part; if you invest $1,000 with the second, you get 1,000 parts. Ignoring spreads, transaction fees and the like, immediately after the purchase, both are worth exactly $1,000 to you. Now, suppose the index goes up 2%.

As you can see, there is no reason to look at the price per share unless you have to buy in terms of whole shares, which is common in the stock market but not necessarily common at all in mutual funds. Because in this case, both funds track the same underlying index, there is no real reason to purchase one rather than the other because you believe they will perform differently. In an ideal world, the two will perform exactly equally. The way to compare the price of mutual funds is to look at the expense ratio. The lower the expense ratio is, the cheaper the fund is, and the less of your money is being eroded every day in fees.

The return of an index fund is always significantly below the return of the underlying commodity. Your best strategy is to invest in something you know and understand.

Buying, reading and following the guidance in these two books is your best investment of time and money.\"", "title": "" }, { "docid": "45970", "text": "\"Index funds can be a very good way to get into the stock market. It's a lot easier, and cheaper, to buy a few shares of an index fund than it is to buy a few shares in hundreds of different companies. An index fund will also generally charge lower fees than an \"\"actively managed\"\" mutual fund, where the manager tries to pick which stocks to invest for you. While the actively managed fund might give you better returns (by investing in good companies instead of every company in the index) that doesn't always work out, and the fees can eat away at that advantage. (Stocks, on average, are expected to yield an annual return of 4%, after inflation. Consider that when you see an expense ratio of 1%. Index funds should charge you more like 0.1%-0.3% or so, possibly more if it's an exotic index.) The question is what sort of index you're going to invest in. The Standard and Poor's 500 (S&P 500) is a major index, and if you see someone talking about the performance of a mutual fund or investment strategy, there's a good chance they'll compare it to the return of the S&P 500. Moreover, there are a variety of index funds and exchange-traded funds that offer very good expense ratios (e.g. Vanguard's ETF charges ~0.06%, very cheap!). You can also find some funds which try to get you exposure to the entire world stock market, e.g. Vanguard Total World Stock ETF, NYSE:VT). An index fund is probably the ideal way to start a portfolio - easy, and you get a lot of diversification. Later, when you have more money available, you can consider adding individual stocks or investing in specific sectors or regions. (Someone else suggested Brazil/Russia/Indo-China, or BRICs - having some money invested in that region isn't necessarily a bad idea, but putting all or most of your money in that region would be. If BRICs are more of your portfolio then they are of the world economy, your portfolio isn't balanced. Also, while these countries are experiencing a lot of economic growth, that doesn't always mean that the companies that you own stock in are the ones which will benefit; small businesses and new ventures may make up a significant part of that growth.) Bond funds are useful when you want to diversify your portfolio so that it's not all stocks. There's a bunch of portfolio theory built around asset allocation strategies. The idea is that you should try to maintain a target mix of assets, whatever the market's doing. The basic simplified guideline about investing for retirement says that your portfolio should have (your age)% in bonds (e.g. a 30-year-old should have 30% in bonds, a 50-year-old 50%.) This helps maintain a balance between the volatility of your portfolio (the stock market's ups and downs) and the rate of return: you want to earn money when you can, but when it's almost time to spend it, you don't want a sudden stock market crash to wipe it all out. Bonds help preserve that value (but don't have as nice of a return). The other idea behind asset allocation is that if the market changes - e.g. your stocks go up a lot while your bonds stagnate - you rebalance and buy more bonds. If the stock market subsequently crashes, you move some of your bond money back into stocks. This basically means that you buy low and sell high, just by maintaining your asset allocation. This is generally more reliable than trying to \"\"time the market\"\" and move into an asset class before it goes up (and move out before it goes down). Market-timing is just speculation. You get better returns if you guess right, but you get worse returns if you guess wrong. Commodity funds are useful as another way to diversify your portfolio, and can serve as a little bit of protection in case of crisis or inflation. You can buy gold, silver, platinum and palladium ETFs on the stock exchanges. Having a small amount of money in these funds isn't a bad idea, but commodities can be subject to violent price swings! Moreover, a bar of gold doesn't really earn any money (and owning a share of a precious-metals ETF will incur administrative, storage, and insurance costs to boot). A well-run business does earn money. Assuming you're saving for the long haul (retirement or something several decades off) my suggestion for you would be to start by investing most of your money* in index funds to match the total world stock market (with something like the aforementioned NYSE:VT, for instance), a small portion in bonds, and a smaller portion in commodity funds. (For all the negative stuff I've said about market-timing, it's pretty clear that the bond market is very expensive right now, and so are the commodities!) Then, as you do additional research and determine what sort investments are right for you, add new investment money in the places that you think are appropriate - stock funds, bond funds, commodity funds, individual stocks, sector-specific funds, actively managed mutual funds, et cetera - and try to maintain a reasonable asset allocation. Have fun. *(Most of your investment money. You should have a separate fund for emergencies, and don't invest money in stocks if you know you're going need it within the next few years).\"", "title": "" }, { "docid": "166597", "text": "Options are contractual instruments. Most options you'll run into are contracts which allow you to buy or sell stock at a given price at some time in the future, if you feel like it (it gives you the option). These are Call and Put options, respectively (for buying the stock and selling the stock). If you have a lot of money in an index fund ETF, you may be able to protect your portfolio against a market decline by (e.g.) buying Put options against the ETF for a substantially lower price than the index fund currently trades at. If the market crashes and your fund falls in value significantly, you can exercise the options, selling the fund at the price that your option has specified (to the counter-party of your contract). This is the risk that the option mitigates against. Even if you don't have one particular fund with your investments, you could still buy a put option on a similar fund, and resell it to another person in lieu of exercise (they would be capable of buying the stock and performing the exercise themselves for profit if necessary). In general, if you are buying an option for safety, it should be an option either on something you own, or something whose price behavior will mimic something you own. You will note that options are linked to the price of stocks. Futures are contracts whose values are linked to the price of other things, typically commodities such as oil, gold, or orange juice. Their behaviors may diverge. With an option you can have a contractual guarantee on the exact investment you're trying to protect. (Additionally, many commodities' value may fall at the same time that stock investments fall: during economic contractions which reduce industrial activity, resulting in lower profits for firms and less demand for commodities.) You may also note that there are other structures that options may have - PUT options on index funds or similar instruments are probably most specifically relevant to your interests.

In many of the futures markets there is a possibility of somebody buying a commodity at the spot price and selling a futures contract on it. In order to do this they need to hold the commodity in storage. Most commodities cost money to hold in storage, so the futures price will tend to be above the spot price for these commodities. In the case of stock index futures, the holder receives a potential benefit from holding the stocks in an index. If the futures market is upward sloping compared to the spot price, then it can be called normal. If the futures market is usually downward sloping compared to the spot price then it can be called inverted. If the futures market is high enough above the spot price so that more of the commodity gets stored for the future, then the market can be called in contango. If the futures market is below the point where the commodity can be profitably stored for the future, and the market can be called in backwardation. In many of these cases, there is an implicit cost that the buyer of a future pays in order to hold the contract for certainly time. Your question is how much money you make if the price of gold goes up by a specific amount, or how much money you lose if the price of gold goes down by the same specific amount. The problem is, you do not say whether it is the spot price or the futures price which goes up or down. In most cases it is assumed that the change in the futures price will be similar to the change in the spot price of gold. If the spot price of gold goes up by a small amount, then the futures price of gold will go up by a small amount as well. If the futures price of gold goes up by a small amount, this will also drive the spot price of gold up. Even for these small price changes, the expected futures price change in expected spot price change will not be exactly the same. For larger price changes, there will be more of a difference between the expected spot price change in expected future price change. If the price eventually goes up, then the cost of holding the contract will be subtracted from any future gains. If the price eventually goes down, then this holding cost should be added to the losses. If you bought the contract when it was above the spot price, the price will slowly drift toward the spot price, causing you this holding cost.

Thus the pitfall is that it is heavily weighted towards (and often tracks) the performance of a few stocks including: Apple, Google (Alphabet), Microsoft, Amazon, Intel and Amgen. It could be argued this is counter intuitive to the general strategy you are trying to employ. This could be tougher to justify. The reason it is potentially not a great idea has less to do with the fact that gold has factors other than just risk on/off and inflation that affect its price (even though it does!); but more to do with the fact that it is harder to own gold and move in and out of positions efficiently than it is a bond index fund. For example, consider buying physical gold. To do so you have to spend some time evaluating the purchase, you are usually paying a slight premium above the spot price to purchase it, and you should usually also have some form of security or insurance for it. So, it has additional costs. Possibly worth it as part of a long-term investment strategy; if you believe gold will appreciate over a decade. But not so much if you are holding it for as little as a few weeks and constantly moving in and out of the position over the year. The same is true to some extent of investing in gold in the form of an ETF. At least a portion of \"\"their gold\"\" comes from paper or futures contracts which must be rolled every month. This creates a slight inefficiency. While possibly not a deal breaker, it would not be as attractive to someone trading on momentum versus fundamentals in my opinion.

It is, at best, a hedge against inflation, since many people feel more comfortable with what they consider \"\"real\"\" money that is not subject to what seems to be arbitrary creation by central banks.

The spot price only applies to large transactions. Retail dealers have costs of doing business that necessitate these fees in order for them to make a profit.

Somebody just has to write down the explanation of what an index tracks, then create ETFs to track the index. By being a \"\"passive investor\"\" you are still making active investing decisions to some degree, in that you need to decide which indexes to passively invest in. If people are not going to attempt to understand the companies they invest in because they're almost certainly better off indexing (which is fine), then the responsibility must fall on someone to make decisions about what are the best rules for the indexes. For most of the history of capital markets, good corporate governance has been enforced by shareholders. If management did something bad, shareholders could vote to replace the Board of Directors and in general they had tools to hold management accountable. Only in recent years, founders of companies like Google, Facebook, Snap, etc., have attempted to subvert this relationship (public shareholders give a company money, and in return the company must answer to the shareholders) and essentially take money for nothing. So far (it's still a pretty short experiment) this has worked as long as the share price is going up, but what happens when it doesn't? What happens when these companies screw up and stop performing well, and there's nothing shareholders can do about it? Investors who intentionally own individual shares will have little to no leverage to demand change, and passive investors would be stuck with some of their money in these companies with terrible governance - and the precedent would only make dual-class and non-voting shares more attractive for future IPOs, making the problem more prevalent.

Below the line I'll address the specific issues. Becoming a US tax resident is a very serious decision, that has significant consequences for any non-American with >$0 in assets. When it involves cross-border business interests, it becomes even more significant. Especially if Switzerland is involved. The US has driven at least one iconic Swiss financial institution out of business for sheltering US tax residents from the IRS/FinCEN. So in a nutshell, you need to learn and be afraid of the following abbreviations: and many more. The best thing for you would be to find a good US tax adviser (there are several large US tax firms in the UK handling the US expats there, go to one of those) and get a proper assessment of all your risks and get a proper advice. You can get burnt really hard if you don't prepare and plan properly. Now here's that bottom line. Q) Will I have to submit the accounts for the Swiss Business even though Im not on the payroll - and the business makes hardly any profit each year. I can of course get our accounts each year - BUT - they will be in Swiss German! That's actually not a trivial question. Depending on the ownership structure and your legal status within the company, all the company's bank accounts may be reportable on FBAR (see link above). You may also be required to file form 5471. Q) Will I need to have this translated!? Is there any format/procedure to this!? Will it have to be translated by my Swiss accountants? - and if so - which parts of the documentation need to be translated!? All US forms are in English. If you're required to provide supporting documentation (during audit, or if the form instructions require it with filing) - you'll need to translate it, and have the translation certified. Depending on what you need, your accountant will guide you. I was told that if I sell the business (and property) after I aquire a greencard - that I will be liable to 15% tax of the profit I'd made. Q) Is this correct!? No. You will be liable to pay income tax. The rate of the tax depends on the kind of property and the period you held it for. It may be 15%, it may be 39%. Depends on a lot of factors. It may also be 0%, in some cases. I also understand that any tax paid (on selling) in Switzerland will be deducted from the 15%!? May be. May be not. What you're talking about is called Foreign Tax Credit. The rules for calculating the credit are not exactly trivial, and from my personal experience - you can most definitely end up being paying tax in both the US and Switzerland without the ability to utilize the credit in full. Again, talk to your tax adviser ahead of time to plan things in the most optimal way for you. I will effectively have ALL the paperwork for this - as we'll need to do the same in Switzerland. But again, it will be in Swiss German. Q) Would this be a problem if its presented in Swiss German!? Of course. If you need to present it (again, most likely only in case of audit), you'll have to have a translation. Translating stuff is not a problem, usually costs $5-$20 per page, depending on complexity. Unless a lot of money involved, I doubt you'll need to translate more than balance sheet/bank statement. I know this is a very unique set of questions, so if you can shed any light on the matter, it would be greatly appreciated. Not unique at all. You're not the first and not the last to emigrate to the US. However, you need to understand that the issue is very complex. Taxes are complex everywhere, but especially so in the US.

In this case, you are technically a Grenzgänger. You will need a specific kind of Swiss permit (\"\"Grenzgängerbewilligung\"\") allowing you to work in Switzerland. Your employer typically takes care of this - they have more experience than you. You being non-EU might make matters a bit more complicated. Your employer will withhold 4.5% of your gross income as source taxes (\"\"Quellensteuer\"\"). When you do your tax declaration, your entire income will be taxed in Germany, since this is where you live. This will happen after your first year of work. Be prepared for a large tax bill (or think of this as an interest-free loan from Germany to you). However, due to the Doppelbesteuerungsabkommen (DBA), the 4.5% you already paid to Switzerland will be deducted from the taxes you are due in Germany. Judging from my experience, the tax authorities in Germany are not fluent in the DBA - particularly in areas far away from the Swiss border. I had to gently remind them to deduct the source taxes, explicitly referring to the DBA. The bill was revised without problems, but I strongly recommend making sure that your source taxes are correctly deducted from your German tax liability. Once your local German tax office understands your situation, you will be asked to make quarterly prepayments, which will be calculated in a way to minimize your later overall tax liability. Budget for these. You didn't ask, but I'll tell you anyway: social security will normally be handled by Switzerland as the country of employment - not the country of residence. Your employer will automatically deduct old age, unemployment and accident insurance and contribute to a pension plan, all in Switzerland. However... ... if you do a lot of your work in Germany (>25%), which certainly applies if you plan on mostly working remotely, your social security will be handled by your country of residence. This is a major pain for your employer, because now your Swiss employer needs to understand the German social security system, how much and to whom to co-pay and so forth. This is a major area of study, and your employer may not want to spend all this effort. My employer has looked at this and requires anyone living outside of Switzerland to limit working from home to less than 25%, because by extension, they would some day also need to do the same for employees living in France, Italy, Austria... or even the UK. They don't want to dig through half the EU states' social security regulations. Therefore, you would not be able to work remotely from Germany for my employer. This is actually a fairly recent development that only entered in force at the beginning of 2015 (before that, this was all a bit of a gray area). Your prospective employer may not be aware of all details. So you will need to think about whether you actively want to point them at this (possibly ruining your plans of working remotely), or not (and possibly getting major problems and post-payments years later). Finally, I think you can choose whether you want to have your health insurance in Switzerland or in Germany (unless your Swiss obligation to be insured is waived because of your part-time status).

So what you are referring to is in Finance something called Funds Transfer Pricing or FTP (often referred to as just Transfer Pricing). Like anything else, FTP has its place. Most companies; however, don't use it properly. FTP, theoretically, has one primary purpose (although it's developed a second): to properly allocate opportunity costs across divisions. Let's say Company A produces widgets. They sell these widgets for $200 at a TOTAL COST of $150 and book profits of $50. Now to produce the widget Division 1 makes a computer chip at a cost of $50 that it then \"\"sells\"\" to Division 2 for $60. Division 1 then books a profit of $10. Division 2 then makes some plastic stuff and assembles the device. This is labor intensive so Division 2's costs are $100. Company A sells the completed device for $150. Division 2 subsequently books profits of $40, and appears much more profitable than Division 1, on the surface. The problem arises when Division 1 could sell the chip to the open market for $125. Now it costs them $50 to produce, and they could make a theoretical profit of $75. This is MORE than the company makes AS A WHOLE on the entire device. By having Division 2 pay effectively \"\"fair market price\"\" for that chip, you realize that Division 2 is really operating at a loss (the *opportunity cost* of not selling the chip to market is greater than producing the completed device). Company A would be better off getting rid of Division 2 and solely focusing on Division 1. In a good FTP system, Division 2 would pay the fair market price of $125. If done properly, management would hopefully realize it should divest Division 2. That's the ***fundamental premise*** behind FTP. In actuality things get much more complicated because of economics, the company itself, branding, IT, operations, management, PPE, labor laws, etc. Thats why most companies screw it up. All that other stuff falls under whats called cost allocation accounting. It gets VERY complex and entire masters courses are dedicated to it (different methods, etc.) The other thing you can do with FTP is get crazy tax breaks due to various tax laws. The simplified explanation is that divisions pay taxes on profits to the government ***that division*** is located in (this works on the state level, too btw.). GE does a lot of this and it's a big part of why they pay almost no-taxes. Again, it gets more complicated when you involve audits as there's some grey area legally. For simplicity, assume tax rates are 40% in the US and 10% in India. So let's say GE makes an airplane engine in the US but \"\"finishes\"\" manufacturing in India. These specific engines costs $5,000,000 for the US division to make, up to a certain point. The US division can then sell the engine at a break even to India. So India \"\"pays\"\" $5,000,000 for the engine. The US division then books no profit. India finishes the manufacturing with additional costs of $1,000,000. The India division then sells the engine to the open market for $9,000,000 . Therefore, the India division books a profit of $3,000,000 and pays taxes of $300,000. Now GE as a whole makes a profit of $3,000,000 less taxes of $300,000 = net profit of $2,700,00. Further, let's say the fair market value of the engine, as is, when the US sells to India is $7,000,000. That would mean US ***should*** book profits of $2,000,000 and India ***should*** book profits of $1,000,000. Total taxes by GE are now $800,000 (US) + $100,000 (India) = $900,000. However, what's important is that NET PROFIT is now $2,100,000. ***GE just saved $600,000 in taxes by doing this***. The beauty of this is, divisions are supposed to charge fair market value for products FTP'd internationally; however, it's REALLY hard for the IRS to say what the value of an unfinished product really is (heck, you could be offering bulk discounts, etc.)... The fact is, often, US divisions have skilled labor that is difficult to replicate elsewhere. They just show US divisions operating at losses to make the company as a whole better. The problem, again, arises when top management don't fully appreciate or understand the reasoning behind this stuff. They end up making cuts to US labor because it's \"\"unprofitable\"\" without thinking about the entire story. I know this is very long winded but hope it helps! ***tldr; companies FTP to recognizes profitability and opportunity costs of divisions as well as use it for overseas tax breaks.*** Side note: Politically speaking, people who know how this works are pissed off about it in the U.S. (don't worry though, most politicians on both sides don't have a clue). We have high corporate tax rates relative to other countries and IRS loopholes allow this kind of thing (lobbying $$). It's also why, economically, you can't just raise ***corporate*** tax rates to increase domestic tax reciepts as more companies will just implement this process (it's complicated to do properly).

Does my net paycheck decrease as the year goes on due to tax brackets filling up?
[ { "docid": "386264", "text": "In general no, if you just have one employer and work there with the same salary for the whole year. Typically an employer does tax withholding by extrapolating your monthly income to the entire year and withholding the right amount so that at the end, what is withheld is what you owe. It's not a surprise to them when your income crosses a tax bracket threshold, because they knew how much they were paying you and knew when you would cross into another bracket, so they factored that in. If you have multiple jobs or only worked for part of the year, or if your income varied from month to month (e.g., you got a raise) there could be a discrepancy between what is withheld and what you owe, because each employer only knows about what it's paying you, not what money you may have earned from other sources.

You can adjust your withholdings on form W-4 if needed, to tell the employer to withhold more or less than they otherwise would.", "title": "" }, { "docid": "192428", "text": "No, you will (generally speaking) not see a decrease in your net earnings from crossing a tax bracket: This means that your highest marginal rate (the top bracket you fall into) only applies to the portion of your income that is in that bracket, not your total income. This helps ensure that your total tax burden does not increase measurably from crossing a tax bracket. Be aware that you can still see measurable changes in your total taxes due if increases in income make you no longer eligible for certain deductions and/or benefits that were otherwise reducing your tax burden, but this is not the same as how changes in your highest marginal rate affect your overall average tax rate. Note that when you see a rate table such as the one on efile.com's federal income tax rates page or on Wikipedia's Income tax in the United States page, the rates listed are for each segment of income, not for your overall income: In other words the 15% rate below (for 2014, filing single) only applies to the portion of your income falling between the listed numbers, not to income below it or above it: that would be calculated under the respective rates given. You can use the i1040tt tax tables to gain a sense of how this works in practice: (The linked resource is for 2014 taxes) The threshold in 2014 for the 25% rate vs 15% was $36,900. Using the linked table, if you were single and made between 36,850 and 36,900 in gross income, your tax liability before other considerations was $5,078.

Another way of putting that is that in practice you only get the tax brackets allocated proportionately throughout the year - so up till the end of August you'll only have been assigned 8/12 of the $37450 bracket, and so on. So if your income doesn't change and your general tax affairs don't change, your paycheck also shouldn't change. If your income is irregular or changes during the year then things can get more complicated. As other answers have noted, withholdings are calculated according to tables that normally just take into account that specific month's income. There are various possible changes to your tax affairs that might cause the withholdings to change. For example there'd be an impact from any change in your contributions to tax advantaged things like health insurance or retirement, health or education savings.

Assuming your gross pay and exemptions do not change, this usually results in a zero-sum for taxes owed (you will receive nothing, and owe nothing). As you can see from the charts, the year is basically broken down into equal tax units that reflect how much you would owe if you worked at that bracket all year. This estimation works best when you have steady hours from check to check. In other words, your taxes are based on the estimate of what you'd make if you earned that much all year, scaled down to the time frame (e.g. 1/52 if you are paid weekly, or 1/26 if you paid biweekly). They do not go \"\"up\"\" near the end of the year, because they're estimated in advance. You don't move up a tax bracket, but are instead taxed at a particular bracket every paycheck. There's also other forms of estimation mentioned there, but basically follow the same scheme. Note that all estimation forms are just that-- estimates. It's best to use a calculator and compare your current taxes whenever a significant change occurs-- a raise, a new child, getting married or divorced, etc. You'll want to be able to alter your exemptions so that enough taxes are coming out. That's also the reason for the \"\"withhold extra\"\" box, so that you can avoid owing. For example, if you're making $44 a week for the first 26 weeks, and then you make $764 a week for the second 26 weeks of the year, you'll end up with an actual tax liability of $2,576.6, but end up paying only $2,345.20. You would owe $231.40. Of course, the actual math is a lot more complicated if you're an employee paid by the minute, for example, or you have a child, go to college, etc. Paychecks that vary wildly, like $10,000 one week and $2,000 the next tend to have the hardest-to-predict estimates (e.g. jobs with big commission payouts). You should avoid living check-to-check with jobs that pay this way, because you'll probably end up owing taxes. Conversely, if you've done your estimates right and you're paid salary or exactly the same number of hours every week, you'll find that the taxes are much easier to predict and you can usually easily create a refund situation simply by having the correct exemptions on your check.

You can request that additional money be withheld (not an issue here) or you can have reduced withholding by claiming additional allowances on a W-4 (i.e., more than just for you and spouse and dependents) if you believe that this will result in withholding that will more closely match the tax due. (Note added in edit):Page 2 of the W-4 form has worksheets that can be used to figure out how many additional allowances to request. Also, I wonder if your withholding will be 37% or final tax bill be 26% of your adjusted gross income. The tax brackets are the tax on marginal income. If you are in the 28% tax bracket, you owe 28 cents in tax for each additional dollar of income, not 28 cents in tax for every dollar of income. Your overall tax might well be less than 20% of your income. As a specific example, in 2011 a married taxpayer filing jointly would be in the (highest) 35% tax bracket if the taxable income was $379,150 or more (marginal tax rate of 35% is applicable to every dollar more than $379,150) but the tax on $379,150 itself works out to be $102,574 or 27.05% of the taxable income. So if you do expect to be earning around $350K or more in salary between now and December 31 to hit that 26% that you expect you will owe, you might want to consider paying a tax accountant for advice on how to fill out your W-4 form for your new employer rather than relying on an Internet forum such as this for free advice. Note added in edit: Your comment \"\"... it is a cocktail of ... federal taxes, state taxes, local taxes, health care ...\"\" on the earlier version of my answer does raise the question of whether you want your employer to withhold 26% instead of 37% and have the money go to meet all these obligations or just 26% towards your Federal income tax liability only. The Federal W-4 form affects only how much money is withheld from your paycheck and sent to the US Treasury. Some of the money that each of your employers withholds (Social Security and Medicare taxes) is not affected by what you put down on the W-4 form. Now, if you hold two jobs and the total income shown on your W-2s is larger than the SS limit, you will have had too much Social Security taxes withheld, and the excess will be a credit towards your Federal income tax liability. You have self-employment income too on which you owe Social Security and Medicare taxes and you are making estimated tax payments. The excess Social Security tax payment can count towards this too (as well as income tax on your Schedule C income). Thus, if your new employer is withholding too much, you might be able to skip making the fourth quarterly payment of estimated tax or make a reduced payment (there is no requirement that the four installments must be equal). In short, there are lots of ramifications that you need to take into account before deciding that 26% is the right number. Instead of filling out a W-4 all by yourself right away, I strongly recommend reading up a lot on income taxes, or play with a tax preparation program (last year's version will do a pretty good job of at least getting you in the right ballpark), or consult with a tax accountant.\"", "title": "" }, { "docid": "1705", "text": "\"Yes, your tax bracket is 25%.

Most payroll systems use what this publication defines as the \"\"Percentage Method\"\", because it requires less data to be entered into the system in order to correctly compute the amount of withholding. The computation method is as follows: Taxes are computed \"\"piecewise\"\"; dollar amounts up to A are taxed at X%, and then dollar amounts between A and B are taxed at Y%, so total tax for B dollars is A*X + (B-A)*Y. Here is the table of rates for income earned in 2012 on a daily basis by a person filing as Single: To use this table, multiply all the dollar amounts by the number of business days in the pay period (so don't count more than 5 days per week even if you work 6 or 7). Find the range in which your pay subject to withholding falls, subtract the \"\"more than\"\" amount from the range, multiply the remainder by the \"\"W/H Pct\"\" for that line, and add that amount to the \"\"W/H Base\"\" amount (which is the cumulative amount of all lower tax brackets). This is the amount that will be withheld from your paycheck if you file Single or Married Filing Separately in the 2012 TY. If you file Married Filing Jointly, the amounts defining the tax brackets are slightly different (there's a pretty substantial \"\"marriage advantage\"\" right now; withholding for a married person in average wage-earning range is half or less than a person filing Single.). In your particular example of $2500 biweekly (10 business days/pp), with no allowances and no pre-tax deductions: So, with zero allowances, your employer should be taking $451.70 out of your paycheck for federal withholding.

But, you also don't get a refund on those when you fill out the 1040 (except if you claim deductions against state income tax, and in an exceptional case which requires you to have two jobs in one year, thus doubling up on SS and SUTA taxes beyond their wage bases). If you claim 3 allowances on your federal taxes, all other things being equal, your taxable wages are reduced by $438.45, leaving you with taxable income of $2061.55.

It seems odd that you would owe that much in taxes with your withholding effectively maxed out, unless you have some other form of income that you're reporting such as investment gains, child support/alimony, etc. With nobody claiming you as a dependent and no dependents of your own, filing Single, and zero allowances on your W-4 resulting in the tax withholding above, a quick run of the 1040EZ form shows that the feds should owe YOU $1738.20.

Meanwhile the FICA rate on average &amp; median payroll (wages/salaries of \"\"workers\"\" and \"\"mid-level managers\"\", etc) increased from 1% to 15% -- that's a 15x increase, or put another way, it is an increase of 1,500% during less than a single working career (the cost of absolutely NOTHING ELSE in the history of our society increased at anything like that rate; not even education and health care costs, nor even \"\"housing\"\" at the peak of the bubble -- and in actuality, just about everything else {including the notorious \"\"gasoline\"\" sold by those \"\"evil\"\" petroleum companies} actually DECREASED during the same time frame). And then, during virtually the SAME time period, those other taxes increased in a similar (if less egregious) fashion. For example in my Midwestern state, there was no sales tax at all circa 1950. A bit over a decade later, when it was first instituted it was initially set at 3%, but applied only to a select category of goods; subsequently the rate was increased (to 4%, then 5%, then with the addition of various county and municipal \"\"sales taxes\"\" to 6% and higher), and more critically, the goods and services that are subject to the tax has increased as well (many of them already with \"\"hidden/buried\"\" excise taxes -- so a large portion of the sales tax is actually a \"\"tax on a tax\"\"). When you realize that as wealth increases, the average expenditure on taxable goods tends does NOT tend increase in anything like a directly proportional manner (i.e. while a person making $50k a year, may pay more than 2x the total sales tax than someone making $25k a year {simply because a big part of the $25k a year goes to \"\"basic necessities\"\" of food, rent, etc}, and it is even possible that the person making $100k a year pays a simple 2x in sales tax of the $50k person... but the $1M a year is HIGHLY unlikely to be paying 10x the sales tax as the $100k a year person) then you begin to realize the way that the \"\"regressive\"\" form of those taxes work -- basically \"\"hobbling\"\" the middle class and preventing it from reaching \"\"upper\"\" middle class status. Now to be ruthlessly blatantly forthright, it is NOT simply a matter of blaming the \"\"rich\"\" -- because the lion's share of those \"\"taxes\"\" were and are being used to \"\"redistribute\"\" money to an ever increasing number of non-working people (either retirees, or \"\"disabled\"\" former workers, etc) -- the vast majority of which were things \"\"demanded\"\" by the general population. Hence the TANSTAAFL reality. The means that the \"\"rich/elites\"\" have used to milk &amp; bilk the system may be *indirectly* linked to those taxes, but in general are actually much more likely to be based on other things (access to leverage/credit &amp; the socialization of bad bets/losses, avoidance of \"\"wages\"\" and emphasis on \"\"capital gains\"\", etc). Doesn't mean the elites/wealthy AREN'T gaming/scamming the system (indeed, many of them are) -- but at least a significant part of the \"\"blame\"\" for the burdensome tax system lies with the people themselves. As another example of the same thing, take \"\"healthcare insurance\"\" -- people want their \"\"insurance\"\" to not only cover the rare, large expenses (cancer treatment, major accident trauma, etc); but also to cover their \"\"annual checkups\"\", etc. -- and then are shocked (shocked I say) when their insurance premiums go UP. Well, what do people expect? If virtually everyone goes for an annual checkup, and that checkup costs per policy are say $300 a year, then how can premiums NOT go up by approximately $300 (+ administration costs)? Did they expect the money to pay those things to magically appear out of nowhere? Seriously; you demand something and eventually (one way or another) you are going to pay for it. --- So in your father and grandfathers eras, they were able to support a larger family in no small part because they were NOT paying for all of those \"\"safety net\"\" things. In addition, for what little \"\"safety net\"\" *did exist* at the time, the people collecting on it were [demographically tiny versus the larger working/paying class](http://www.ssa.gov/history/ratios.html) (i.e. in 1940 each retiree on social security was \"\"supported\"\" by nearly 160 workers; by 1950 the ratio was a tenth of that 1 retiree supported by 16 workers; by 1965 it was a quarter of that {1/40th of the 1940 ratio}, 1 retiree to 4 workers; and currently {2009} it is a 1 to 3 ratio {and set to get a LOT worse as the \"\"Baby Boomer Bulge\"\" retires en masse in the coming decade+}.) So basically, your single income job still IS supporting a large \"\"family\"\" -- you just aren't supporting them *directly* any more {instead you pay the government, and they get checks \"\"from the government\"\"}; and the \"\"family\"\" you are supporting is probably NOT biologically related to you (i.e. they are someone *else's* kids, parents, etc). And then, just as importantly, since you are no longer *directly* supporting a large family, YOU have essentially ZERO control over the hows/whens/whys of how the money gets spent (whereas your father and grandfather DID get to decide) -- instead the monies are being tossed as \"\"entitlements\"\" to the recipients, who, since they have been told (and certainly WANT to believe) that they are just getting \"\"what they are due\"\", don't feel that anyone has any RIGHT to tell them how to spend it. (Sorta like as if when your father and grandfather were working, as if their wife, and each of their kids {as well as great grandpa Joe in the back bedroom, and maybe the \"\"disabled neighbor\"\" Dave} was LEGALLY GRANTED a government mandated \"\"allowance\"\" of 1/10th of your dad/grandad's paycheck -- and instead of your dad/grandad getting his full paycheck, the government required his employer to cut several paychecks paying those \"\"allowances\"\" directly to the wife, kids {whose checks would go directly to their schools}, grandpa joe, neighbor Dave, etc -- and they {other than the kids} were then able to spend it on whatever they wanted, and your dad/grandad wouldn't have been able to say \"\"boo\"\" about it.)

So if you were going to owe $400 in April, one few exemption will have you overpay $170. i.e. in this 15% bracket, each exemption changes annual withholding by that $570.

In 2015, 42% of companies offered a dollar for dollar match on deposits. Can't beat that. (Note - to respond to Xalorous' comment, the $18K OP deposits can be nearly any percent of his income. The typical match is 'up to' 6% of gross income. If that's the case, the 401(k) deposits are doubled. But say he makes $100K. The $18K deposit will see a $6K match. This adds a layer of complexity to the answer that I preferred to avoid, as I show with no match at all, and no change in tax brackets, the deferral alone shows value to the investor.) On to the main answer - Let's pull out a spreadsheet - We start with $10,000, and assume the 25% bracket. This gives a choice of $10,000 in the 401(k) or $7500 in the taxable account. Next, let 20 years pass, with 10% return each year. The 401(k) sees the full 10% and after 20 years, $67K. The taxable account owner waits to get the 15% cap gain rate and adjusts portfolio, thus seeing an 8.5% return each year and carrying no ongoing gains. After 20 years of 8.5% returns, he has $38K net. The 401(k) owner on withdrawal pays the 25% tax and has $50K, still more than 25% more money that the taxable account. Because transactions within the account were all tax deferred. EDIT - With respect to davmp's comment, I'll offer the other extreme - In his comment, he (rightly) objected that I chose to trade every year, although I did assign the long term 15% cap gain rate, he felt the annual trade was my attempt to game the analysis. Above, I offer his extreme case, a 10% return each year, no trade, no dividend. Just a cap gain at the end. The 401(k) still wins. I also left the tax (on the 401(k)) at withdrawal at 25%, when in fact, much, if not all will be taxed at 15% or lower, which would put the net at $57K or 30% above the taxable account final withdrawal. The next issue I'd bring up is that the 401(k) is taken out at the top (marginal) tax rate, e.g. a single filer with taxable income over $37,650 (in 2016) would save 25% on that 401(k) deduction. Of course if the deduction pulls you under that line, I'd go Roth or taxable. But, withdrawals start at zero. Today, a single retiree has a standard deduction ($4050) and exemption ($6300) for a total $10,350 \"\"zero bracket\"\" with the next $9275 taxed at 10%. This points to needing $500K in pre tax accounts before withdrawals each year would get you past the 10% bracket. (This comes from the suggestion of using 4% as an annual withdrawal rate). Last - the tax discussion has 2 major points in time, deposit and withdrawal, of course. But, the answers here all ignore all the time in between. In between, you see that for any number of reasons, you'll drop from the 25% bracket to 15% that year. That's the time to convert a bit of money to Roth and 'top off' the 15% bracket. It can happen due to job loss, marriage with new spouse either not working or having lower income, new baby, house purchase, etc. Or in-between, a disability put you out of work. That permits you to take money out with no penalty, and little chance of paying even the 25% that you paid going in.

While I am not all that savvy on payroll procedures, I recall an article that indicated some companies only send in withheld taxes every quarter, much like you are doing now. They get a short term interest free loan. For example taxes withheld by a w-2 employee in the later months of the year may not be provided to the IRS until 15 January of the next year.

This question motivated me to do a little research. It appears that what happens is that (take a deep breath) the capital gain does push you into the next tax bracket, but the capital gain is always interpreted as the \"\"last\"\" income you received, so that if your non-capital-gains income is less than the threshold, it will all be taxed in the lower bracket, and only your capital gain will be taxed in the higher bracket (but it will be taxed at the capital-gains rate of that higher bracket). In short, a capital gain can only push capital gains into higher capital-gains tax brackets; it cannot push ordinary income into higher ordinary-income tax brackets. In addition, the amount of the capital gain is taxed in a marginal fashion, such that any portion of the gain that will \"\"fit\"\" into a lower bracket will be taxed at a lower level, with only the topmost portion of any gain being taxed at the top rate. This site is one claiming this: Will capital gain or dividend income push my other income into a higher tax bracket? No, the tax rates apply first to your “ordinary income” (income from sources other than long-term capital gains or qualifying dividends) so these items that are taxed at special rates won’t push your other income into a higher tax bracket. If my ordinary income puts me in the 15% tax bracket, can I receive an unlimited amount of long-term capital gain at the 0% rate? No, the 0% rate applies only to the amount of long-term capital gain and dividend income needed to “fill up” the 15% tax bracket. For example, if your ordinary income is $4,000 below the figure that would put you in the 25% bracket and you have a $10,000 long-term capital gain, you’ll pay 0% on $4,000 of your capital gain and 15% on the rest.

First, you need to understand that there will be taxes withheld from your paycheck, but the amount that they withhold is simply a guess. You might pay too much or too little tax during the year. After the year is over, you'll send in a tax return form that calculates the correct tax amount. If you have paid too little over the year, you'll have to send in the rest, but if you've paid too much, you'll get a refund. There are complicated formulas on how much tax the employer withholds from your paycheck, but in general, if you don't have extra income elsewhere that you need to pay tax on, you'll probably be close to breaking even at tax time. When you get your paycheck, the first thing that will be taken off is FICA, also called Social Security, Medicare, or the Payroll tax. This is a fixed 7.65% that is taken off the gross salary. It is not refundable and is not affected by any allowances or deductions, and does not come in to play at all on your tax return form. There are optional employee benefits that you might need to pay a portion of if you are going to take advantage of them, such as health insurance or retirement savings. Some of these deductions are paid with before-tax money, and some are paid with after tax money. The employer will calculate how much money they are supposed to withhold for federal and state taxes (yes, California has an income tax), and the rest is yours. At tax time, the employer will give you a form W-2, which shows you the amount of your gross income after all the before-tax deductions are taken out (which is what you use to calculate your tax). The form also shows you how much tax you have paid during the year. Form 1040 is the tax return that you use to calculate your correct tax for the year. You start with the gross income amount from the W-2, and the first thing you do is add in any income that you didn't get a W-2 for (such as interest or investment income) and subtract any deductions that you might have that are not taxable, but were not paid through your paycheck (such as moving expenses, student loan interest, tuition, etc.) The result is called your adjusted gross income. Next, you take off the deductions not covered in the above section (property tax, home mortgage interest, charitable giving, etc.). You can either take the standard deduction ($6,300 if you are single), or if you have more deductions in this category than that, you can itemize your deductions and declare the correct amount. After that, you subtract more for exemptions. You can claim yourself as an exemption unless you are considered a dependent of someone else and they are claiming you as a dependent. If you claim yourself, you take off another $4,000 from your income. What you are left with is your taxable income for the year. This is the amount you would use to calculate your tax based on the bracket table you found. California has an income tax, and just like the federal tax, some state taxes will be deducted from your paycheck, and you'll need to fill out a state tax return form after the year is over to calculate the correct state tax and either request a refund or pay the remainder of the tax.

That's the cooler thing, when your investments mean you don't have to go to work! I don't mean donate ALL of it to charity. But feel free. If you hold a security more than one year, and donate it to charity, you get a tax deduction for the appreciated value (even though the security didn't actually cost you that). (link) Do not convert the BTC to cash then donate the cash. Donate it as BTC. Your tax deduction works against your highest tax bracket. If you are paying in a 28% tax bracket (your next $100 of income has $28 tax), then for every $100 of charitable donation, you get $28 back on Federal. It does the same to state tax, and you also avoid the 10-15% capital gains tax because you didn't sell the securities. Do your 1040 both ways and note the difference.***** Your charitable deduction of appreciated securities is capped at 30% of AGI. Any excess will carryover and becomes a tax deduction for the next year, and it can carryover for several years. ** Use a donor-advised fund. If you have are donating more than $5000, you don't need to search for a charity that will take Bitcoin, and you also don't need to pick a charity now. Instead, open a special type of giving account called a Donor-Advised Fund. The DAF, itself, is a charity. It specializes in accepting complex donations and liquidating them into cash. The cash credits to your giving account. You take the tax deduction in the year you give to the DAF. Then, when you want to give to a charity, you tell the DAF to donate on your behalf***. You can tell them to give on your behalf anonymously, or merely conceal your address so you don't get the endless charity junk mail. The DAF lets you hold the money in index funds, so your \"\"charity nest egg\"\" can grow with the market. Mine has more than doubled thanks to the market. This money is no longer yours at this point; you can't give it back to yourself, only to licensed charities. The Fidelity Donor Advised Fund makes a big thing of taking Bitcoin, and I really like them. **** I love my DAF, and it has been a charitable-giving workhorse. It turns you into a philanthropist, and that changes you life in ways I cannot describe. Certainly makes me more level-headed about money. Lottery winner syndrome is just not a risk for me (partly because I'm now on the board of charities, and oversee an endowment.) Donating generally will reduce suspicion (criminals don't do that), but donating to a DAF even moreso. Since the DAF would have to return ill-gotten gains, they're involved. Their lawyers will back you up. The prosecutor is up against a billion dollar corporation instead of just you. With Fidelity particularly, Bitcoin is a crusade for them, and their lawyers know how to defend Bitcoin. A Fidelity DAF is a good play for that reason alone IMO. ** The gory details: Presumably you are donating to regular charities or a Donor Advised Fund, and these are \"\"50% limit organizations\"\". Since it's capital gains, you have a 30% limit. If your donation is more than 30% of AGI, or if you have carryover from last year, you use Worksheet 2 in Publication 526. You plug your donations into line 4, then the worksheet grinds through all the math and shows what part you deduct this year and what part you carryover to the next year. *** I specifically asked managers at two DAFs whether they were OK with someone donating a complex asset to the DAF, and immediately giving the entire cash amount to a charity. The DAF doesn't get any fees if you do that. They said not only are they OK with it, most of their donors do exactly that and most DAF accounts are empty. They make it on the 0.6% a year custodial fee on the other accounts, and charitable giving to them. Mind you, you can only donate to 501C3 type charities, what IRS calls \"\"50% limit organizations\"\". This actually protects you from donating to organizations who lie about their status. **** I'm not with Fidelity, but I am a satisfied DAF customer. The DAF funds its overhead by deducting 0.6% per year from your giving account. If you invest the funds in a mutual fund within the DAF, that investment pays the 0.08% to 1.5% expense ratio of the fund. I can live with that. ***** I just Excel'd the value of donating $100 of appreciated security instead of taking it as capital gains income. 28% Fed tax, 15% Fed cap gains, 8% state tax on both. Take the $100 as income, pay $23 in cap gains tax. Donate $100 in securities, the $23 tax goes away since you didn't sell it. Really. The $100 charitable deduction offsets $100 in income, also saving you $36 in regular income tax. Net tax savings $59. However you lost the $100! So you are net $41 poorer. It costs you $41 to donate $100 to charity. This gets better in higher brackets.\"", "title": "" }, { "docid": "258423", "text": "\"What I've found works best when working on my personal budget is to track my income and spending two different ways: bank accounts and budget categories. Here is what I mean: When I deposit my paycheck, I do two things with it: It goes into my checking account, so the balance of my checking account goes up by the amount of my paycheck. I also \"\"deposit\"\" the money from my checking account into my various budget category balances. This is separate from my bank account balances. Some of my paycheck money goes into my groceries category, some goes into clothing, some into car fuel, entertainment, mortgage, phone, etc. Some goes into longer range bills that only happen once or twice a year, such as car insurance, life insurance, property tax, etc. Some goes into savings goals of ours, such as car replacement, vacation, furniture, etc. Every dollar that we have in a bank account or in cash in our wallets is also accounted for in a budget category. If you add up the balances of our bank accounts and cash, and you add up the balances of our budget categories, they add up to the same number. When we make a purchase, this also gets accounted for twice: The appropriate bank account (or cash wallet) balance gets reduced by the purchase amount. The appropriate budget category gets reduced by the purchase amount. In this way, we don't really need to worry about having separate bank accounts for different purposes. We don't need to put our savings goal money in a separate bank account from our grocery money, if we don't want to. The budget category accounting keeps track of how much money is allocated to each purpose. Now, the budget category amounts are not spent yet; the money in them is still in our bank account, and we can move money around in the categories, if we change our mind on how to allocate them. For example, if we don't spend all of our gas money for the month, we can either keep that money in the gas category, or we can move it to a different category, such as the car replacement category or the vacation category. If the phone bill is more than we expect, we can move money around from a different category to cover it. Now, back to your question: We allocate some money from each paycheck into our furniture category. But the money is not really spent until we actually buy some furniture. When we do, the furniture category balance and bank account balance both go down by the amount of the purchase. All of this can be kept track of on the computer in a spreadsheet. However, it's not easy to keep track of so many categories and bank balances. An easier solution is custom budgeting software designed for this purpose. I use and recommend YNAB.\"", "title": "" }, { "docid": "64257", "text": "So the principle is true. Assuming that you get paid bi-weekly, you end up getting three paychecks two months during the year. Typically that is in January and July/August. So if things were different, and your mortgage was setup so you paid half a monthly payment each paycheck, then you would wind up making one full extra payment per year. Making that extra payment, most often, reduces the mortgage by 7 years on a 30 year note. While true, many of these companies charge exorbitant fees for the right for you to do so, so the principal reduction is not commensurate with what you are paying. You can simply do this yourself without paying fees. On those extra pay days, pay half a payment to principal only, and no fee, no fuss. This is pretty easy to do with most mortgage companies as they have online payments and it is just a matter of filling out a web form.

You're single, you're possibly still a dependent on your parent's taxes (in lieu of rent), and you're finally bringing home bacon instead of bacon bits. Welcome to the working world. Let's say your gross salary is the U.S. median of $50,000. With bi-weekly checks (26 a year; common practice) you're getting $1923.08 per paycheck. In the 2013 \"\"Percentage Method\"\" tax tables, here's how your federal withholding is calculated as a single person paid biweekly: Federal taxes are computed piecewise; the amount up to A is taxed at X%, then the amount between A and B is taxed at Y%, so if you make $C, between A and B, the tax is (A*X) + (C-A)*Y. The amount A*X is included in the \"\"base amount\"\" for ease of calculation. Back to our example; let's say you're getting $1923.08 gross wages per check. That puts you in the 25% marginal bracket. You pay the sum of all lesser brackets (which is the \"\"base amount\"\" of the 25% bracket), plus the 25% marginal rate on every dollar that falls within the bracket. That's 191.95 + (1923.08 - 1479) * .25 = 191.95 + (444.08 * .25) = 191.95 + 111.02 = $302.97 per paycheck. The \"\"effective\"\" tax rate on the total amount, as if you were being charged a flat tax, is 15.75%, and this is just for the federal income tax. Add to this MA state income taxes (5.25% flat tax), FICA (aka Medicare; 1.45% flat) and SECA (aka Social Security; 6.2% up to a \"\"wage base\"\" that $50k doesn't even approach), and your effective tax rate on each dollar you earn is 15.75% + 5.25% + 1.45% + 6.2% = 28.65%. This doesn't include any state unemployment taxes that may be withheld separately, but as the rate I come up with is pretty darn close to what you've figured (meaning I slightly overestimated your gross income and thus your effective tax rate), my bet is that SUTA's either employer-paid in MA, or it's just part of MA state income tax. It gets better, at least at the federal level: The amount of your state income taxes is tax-deductible at the federal level if you itemize your deductions. That may not be a factor for you as you'd have to come up with more than $6,100 of other tax-deductible expenses to make itemizing the better option than taking the standard deduction (big-ticket items are mortgage expenses other than principal payments, hospital stays such as for childbirth or major accident, and state and local taxes such as sales, property and income). If you can claim yourself as a dependent (meaning your parents can't), then $150 of each check ($3,900 of your annual salary) is no longer taxed for federal withholding, lowering the amount of money taxed at the 25% marginal rate. You effectively save $37.50 biweekly ($975 annually) in taxes. Get married and file jointly, and your spouse, her personal exemption, and an extra standard deduction amount (if you don't itemize) go on your taxes. The tax rates for married couples filing jointly are also lower; they're currently calculated (or were in 2012) to be the same as if two equal earners were to file separately, so if your spouse doesn't work, your taxes on the single income are calculated at the rates you'd get if you earned half as much. It doesn't work out to half the taxes, but it is a significant \"\"marriage advantage\"\". Have kids, and each one is another little $3,900 tax write-off. It's nowhere near the cost of having or raising the child, but it helps, and having kids isn't about the money. Owning a home, making charitable deductions, having medical expenses, etc are a toss-up. The magic number in 2013 is $12,200 for a married couple, $6,100 for a single person. If your mortgage interest, insurance premiums, property taxes, medical expenditures, charitable donations, any contributions from your take-home pay to a tax-deferred savings account (typically these accounts are paid into by your employer as a \"\"pre-tax deduction\"\" and never show up as taxable income, but you could just as easily move money from your take-home pay into tax-deferred savings) and any other tax-deductible payments add up to more than 12 large, then itemize. If not, take your standard deduction. As a single taxpayer just starting out in life, you probably don't have any of these types of expenditures, certainly not enough to give up the SD. I did the math on my own taxes in 2012, and was surprised at how little the government actually gets of my paycheck when all's said and done. Remember back in the summer of 2012 when everyone was mad at Romney for making millions and only paying an effective income tax rate of 14%, which was compared to the middle class's marginal rate of 25-28%? Well, my family of 3, living on a little more than the median income from one earner (me), taking the married standard deduction, three personal exemptions, and a little extra for student loan interest, paid an effective federal income tax rate of something like 3.5%. Of course, the FICA and SS taxes don't allow any deductions (not even for retirement savings), so add in the 4.2% SS (in 2012) and 1.45% FICA and the full federal gimme was more like 9-10%.\"", "title": "" }, { "docid": "439248", "text": "1.If the compensation that I receive is over 10 lakhs, how much would be deducted as tax No tax will be deducted by the company.

What you propose is typically called the back door Roth. You make the (non-deductible) IRA deposit, and soon after, convert to Roth. As long as you have no other existing IRA, the process is simple, and actually a loophole that's still open. If you have an existing IRA, the conversion may be partially taxed based on untaxed balance. As comments frequently get overlooked, I'm adding @DilipSarwate excellent warning regarding this - Depending on the value of the existing Traditional IRA and its pre-existing basis, if any, the backdoor Roth conversion might be almost completely taxable. Example: Traditional IRA worth $250K with zero basis. New nondeductible contribution increase value to $255.5K and basis $5.5K. Converting $5.5K into a Roth IRA leaves $250K in the Traditional IRA with basis $5381.60. That is, of that $5500 conversion, only $118.40 was nontaxable and so, not only is the original $5500 taxable income to the OP but he also owes taxes on $5381.60 of that $5.5K conversion. In short, discussions of backdoor Roth conversions as a great idea should always be tempered with an acknowledgement that it does not work very well if there is any other money in the Traditional IRA. Once that nondeductible contribution enters a Traditional IRA, it does not come out completely until all your Traditional IRA accounts are drained of all money. All your Traditional IRA money is considered by the IRS to be in a single pot, and you can't set up a Traditional IRA (possibly with a new custodian) via nondeductible contribution, convert just that Traditional IRA account into a Roth IRA account, and claim that the whole conversion amount is nontaxable because all the tax-deferred money is in the other IRAs that you haven't touched at all. Last - you disclosed that you are depositing to a Roth 401(k) to the match. Which prompts me to ask if this is best. If your marginal rate is 25% or higher, you are missing the opportunity to save 'off the top', at that rate, and 'fill the lower brackets' at retirement, or, via conversion, any year before then when you are in a lower bracket for whatever reason. See my answer for Saving for retirement: How much is enough? which addresses this further. From new comments - Won't his Roth 401k contributions max out his overall Roth contributions? No. They are separate numbers, each with own annual limits. Wouldn't this prevent any back-door Roth conversions? The 401(k) has no effect on back door Roth, except for the fact that the 401(k) and high income make the Roth IRA unavailable by normal deposit. Back door is the only door. At the end are you encouraging him to look for a Traditional 401(k) at work to max out, then contributing to a Roth? Yes! Read the linked SE article, and consider the annual withdrawal that would get you to 25%.

Also, knowing what tax bracket you're in would help as well, although I certainly understand if you're not comfortable sharing that. So, assuming the US... If you're in the 10% or 15% tax bracket, then you're already not paying any federal tax on the $3k long term gain, so purposely taking losses is pointless, and given that there's probably a cost to taking the loss (commission, SEC fee), you'd be losing money by doing so. Also, you won't be able to buy back the loser for 31 days without having the loss postponed due to the wash sale that would result. State tax is another matter, but (going by the table in this article), even using the highest low end tax rate (Tennessee at 6%), the $50 loss would only save you $3, which is probably less than the commission to sell the loser, so again you'd be losing money. And if you're in a state with no state income tax, then the loss wouldn't save you anything on taxes at the state level, but of course you'll still be paying to be able to take the loss. On the high end, you'd be saving 20% federal tax and 13.3% state tax (using the highest high end tax state, California, and ignoring (because I don't know :-) ) whether they tax long-term capital gains at the same rate as regular income or not), you'd be saving $50 * (20% + 13.3%) = $50 * 33.3% = $16.65. So for taxes, you're looking at saving between nothing and $16.65. And then you have to subtract from that the cost to achieve the loss, so even on the high end (which means (assuming a single filer)) you're making >$1 million), you're only saving about $10, and you're probably actually losing money. So I personally don't think taking a $50 loss to try to decrease taxes makes sense. However, if you really meant $500 or $5000, then it might (although if you're in the 10-15% brackets in a no income tax state, even then it wouldn't). So the answer to your final question is, \"\"It depends.\"\" The only way to say for sure is, based on the country and state you're in, calculate what it will save you (if anything). As a general rule, you want to avoid letting the tax tail wag the dog. That is, your financial goal should be to end up with the most money, not to pay the least taxes.

Note, if you overshoot it, and in April 2016, see that you are say $5K into the 25% rate, you can just recharacterize the amount you went over and nail the bracket to the dollar. If you have the time and patience, you can convert into 2 different Roth accounts. One account for one asset class, say large cap stocks/funds, the other, cash/bonds. In April, keep the account that outperformed, and only recharacterize the lagger. Roth Roulette is my name for this strategy. It's risk free, and has the potential to boost the value of your conversions. Edit - To be clear, you are permitted to recharacterize (undo) any or all of the converted amount. You actually have until tax time (4/15 or so) plus the 6 month extension. You can recharacterize for any reason - A personal anecdote - I manage my mother in law's money. She is well under the 25% bracket cutoff. Each year I convert, and each April, recharacterize just enough to be at the top of the 15% bracket.

If the OP correctly transcribed these income numbers onto his tax returns, correctly computed the tax on the income reported on his 2010 and 2011 1040 forms, and paid the amount due in timely fashion, then there is no tax or penalty due for 2010 and 2011. Nor is the company entitled to withhold tax on this income for 2010 and 2011 at this time; the tax on that income has already been paid by the OP directly to the IRS and the company has nothing to do with the matter anymore. Suppose the value of the rental of the unit the OP is occupying was NOT reported as income on the OP's 2010 and 2011 W-2 forms. If the OP correctly transcribed these income numbers onto his tax returns, correctly computed the tax on the income reported on his 2010 and 2011 1040 forms, and paid the amount due in timely fashion, then there is no tax or penalty due for 2010 and 2011. Should the OP have declared the value of the rental of the unit as additional income from his employer that was not reported on the W-2 form, and paid taxes on that money? Possibly, but it would be reasonable to argue that the OP did nothing wrong other than not checking his W-2 form carefully: he simply assumed the income numbers included the value of the rental and copied whatever the company-issued W-2 form said onto his 1040 form. At least as of now, there is no reason for the IRS to question his 2010 and 2011 returns because the numbers reported to the IRS on Copy A of the W-2 forms match the numbers reported by the OP on his tax returns. My guess is that the company discovered that it had not actually declared the value of the rental payments on the OP's W-2 forms for 2010 and 2011 and now wants to include this amount as income on subsequent W-2 forms. Now, reporting a lump-sum benefit of $38K (but no actual cash) would have caused a huge amount of income tax to need to be withheld, and the OP's next couple of paychecks might well have had zero take-home pay as all the money was going towards this tax withholding. Instead, the company is saying that it will report the $38K as income in 78 equal installments (weekly paychecks over 18 months?) and withhold $150 as the tax due on each installment. If it does not already do so, it will likely also include the value of the current rent as a benefit and withhold tax on that too. So the OP's take-home pay will reduce by $150 (at least) and maybe more if the current rental payments also start appearing on the paychecks and tax is withheld from them too. I will not express an opinion on the legality of the company withholding an additional $150 as tax from the OP's paycheck, but will suggest that the solution proposed by the company (have the money appear as taxable benefits over a 78-week period, have tax withheld, and declare the income on your 2012, 2013 and 2014 returns) is far more beneficial to the OP than the company declaring to the IRS that it made a mistake on the 2010 and 2011 W-2's issued to the OP, and that the actual income paid was higher. Not only will the OP have to file amended returns for 2010 and 2011 but the company will need to amend its tax returns too. In summary, the OP needs to know that He will have to pay taxes on the value of the waived rental payments for 2010 and 2011. The company's mistake in not declaring this as income to the OP for 2010 and 2011 does not absolve him of the responsibility for paying the taxes What the company is proposing is a very reasonable solution to the problem of recovering from the mistake. The alternative, as @mhoran_psprep points out, is to amend your 2010 and 2011 federal and state tax returns to declare the value of the rental during those years as additional income, and pay taxes (and possibly penalties) on the additional amount due. This takes the company completely out of the picture, but does require a lot more work and a lot more cash now rather than in the future.", "title": "" } ]

In 1905 , he played Herod in the English premiere of Oscar Wilde 's Salomé , directed by Florence Farr , impressing critics Max Beerbohm and Robbie Ross . On the basis of this success , he was cast by Farr as Foragel in William Butler Yeats ' The Shadowy Waters . Yeats disliked his performance , complaining that Condamine was `` over-emphatic and shoots his voice up and down the scale in a perfectly accidental way '' and that `` You can not play Foragel without nobility or any of my verse without pride & he has neither . '' Yeats wrote `` I long to get him by myself and make him speak on a note day after day till he had got rid of accidental variety '' but since Condamine and the other actors were performing without pay as a favor to Farr , Yeats could not have him removed from the play .

What is the effect of a cancelled stock order on a stock and the market?
[ { "docid": "261082", "text": "\"That article, like almost any article written by a non-expert and quoting only \"\"research\"\" from lobbying groups, hugely misses the point. The vast majority of orders that end up being cancelled are cancelled as a standard part of exchanges' official market-maker programs. Each exchange wants you and me to know that it has liquidity -- that when we go to buy or sell some stock, there will be someone waiting on the other side of the trade. So the exchange pays (via lowered fees or even rebates) hundreds of registered market makers to constantly have orders resting in each product's order book within a few ticks of the current NBBO or the last trade price. That way, if everyone else should suddenly disappear from the market, you and I will still be able to trade our shares for a price somewhat close to the last trade price. But market makers who are simply acting in this \"\"backstop\"\" role don't actually want to have their orders filled, because those orders will almost always lose them money. So as prices rise and fall (as much as tens of times per second), the market makers need to cancel their resting orders (so they don't get filled) and add new ones at new prices (so they meet their obligations to the exchange). And because the number of orders resting in any given product's order book is vastly larger than the number of actual trades that take place in any given time period, naturally the number of cancellations is also going to hugely outweigh the number of actual trades. As much as 97% to 3% (or even more). But that's completely fine! You and I don't have to care about any of that. We almost never need the market makers to be there to trade with us. They're only there as a backstop. There's almost always plenty of organic liquidity for us to trade against. Only in the rare case where liquidity completely dries up do we really care that the registered market makers are there. And in those cases (ideally) the market makers can't cancel their orders (depending on how well the exchange has set up its market maker program). So, to answer your question, the effect of standard order cancellation on a stock is essentially none. If you were to visualize the resting orders in a product's book as prices moved up and down, you would essentially see a Gaussian distribution with mean at the last trade price, and it would move up and down with the price. That \"\"movement\"\" is accomplished by cancellations followed by new orders. P.S. As always, keep in mind that your and my orders almost never actually make it to a real stock exchange anymore. Nowadays they are almost always sent to brokers' and big banks' internal dark pools. And in there you and I have no idea what shenanigans are going on. As just one example, dark pools allow their operators and (for a fee) other institutional participants access to a feature called last look that allows them to cancel their resting order as late as after your order has been matched against it! :( Regarding the question in your comment ... If Alice is sending only bona fide orders (that is, only placing an order at time T if, given all the information she has at time T, she truly wants and intends for it to be filled) then her cancellation at a later time actually adds to the effectiveness of and public perception of the market as a tool for price discovery (which is its ultimate purpose). [In the following example imagine that there are no such things as trading fees or commissions or taxes.] Let's say Alice offers to buy AAPL at $99.99 when the rest of the market is trading it for $100.00. By doing so she is casting her vote that the \"\"fair value\"\" of a share of AAPL is between $99.99 and $100.00. After all, if she thought the fair value of a share of AAPL was higher -- say, between $100.00 and $100.01 -- then she should be willing to pay $100.00 (because that's below fair value) and she should expect that other people in the market will not soon decide to sell to her at $99.99. If some time later Alice does decide that the fair value of AAPL is between $100.00 and $100.01 then she should definitely cancel her order at $99.99, for exactly the reason discussed above. She probably won't get filled at $99.99, and by sitting there stubbornly she's missing out (potentially forever) on the possibility to make a profit. Through the simple act of cancelling her $99.99 order, Alice is once again casting a vote that she no longer thinks that's AAPL's fair value. She is (very slightly) altering the collective opinion of the entire market as to what a share of AAPL is worth. And if her cancellation then frees her up to place another order closer to her perceived fair value (say, at $100.00), then that's another vote for her honest optinion about AAPL's price. Since the whole goal of the market is to get a bunch of particpants to figure out the fair value of some financial instrument (or commodity, or smart phone, or advertising time, etc.), cancellations of honest votes from the past in order to replace them with new, better-informed honest votes in the present can only be a good thing for the market's effectiveness and perceived effectiveness. It's only when participants start sending non-honest votes (non bona fide orders) that things start to go off the rails. That's what @DumbCoder was referring to in his comment on your original question.\"", "title": "" } ]
[ { "docid": "59638", "text": "\"Yes there is, it is called a One-Cancels-the-Other Order (OCO). Investopedia defines a OCO order as: Definition of 'One-Cancels-the-Other Order - OCO' A pair of orders stipulating that if one order is executed, then the other order is automatically canceled. A one-cancels-the-other order (OCO) combines a stop order with a limit order on an automated trading platform. When either the stop or limit level is reached and the order executed, the other order will be automatically canceled. Seasoned traders use OCO orders to mitigate risk. I use CMC Markets in Australia, and they allow free conditional and OCO orders either when initially placing a buy order or after already buying a stock. See the Place New Order box below: Once you have selected a stock to buy, the number of shares you want to buy and at what price you can place up to 3 conditional orders. The first condition is a \"\"Place order if...\"\" conditional order. Here you can place a condition that your buy order will only be placed onto the market if that condition is met first. Say the stock last traded at $9.80 and you only want to place your order the next day if the stock price moves above the current resistance at $10.00. So you would Place order if Price is at or above $10.00. So if the next day the price moves up to $10 or above your order will be placed onto the market. The next two conditional orders form part of the OCO Orders. The second condition is a \"\"Stop loss\"\" conditional order. Here you place the price you want to sell at if the price drops to or past your stop loss price. It will only be placed on to the market if your buy order gets traded. So if you wanted to place your stop loss at $9.00, you would type in 9.00 in the box after \"\"If at or below ?\"\" and select if you want a limit or market order. The third condition is a \"\"Take profit\"\" conditional order. This allows you to take profits if the stock reaches a certain price. Say you wanted to take profits at 30%, that is if the price reached $13.00. So you would type in 13.00 in the box after \"\"If at or above ?\"\" and again select if you want a limit or market order. Once you have bought the stock if the stop order gets triggered then the take profit order gets cancelled automatically. If on the other hand the take profit order gets triggered then the stop loss order gets cancelled automatically. These OCO conditional orders can be placed either at the time you enter your buy order or after you have already bought the stock, and they can be edited or deleted at any time. The broker you use may have a different process for entering conditional and OCO orders such as these.\"", "title": "" }, { "docid": "525231", "text": "\"There are two distinct questions that may be of interest to you. Both questions are relevant for funds that need to buy or sell large orders that you are talking about. The answer depends on your order type and the current market state such as the level 2 order book. Suppose there are no iceberg or hidden orders and the order book (image courtesy of this question) currently is: An unlimited (\"\"at market\"\") buy order for 12,000 shares gets filled immediately: it gets 1,100 shares at 180.03 (1,[email protected]), 9,700 at 180.04 and 1,200 at 180.05. After this order, the lowest ask price becomes 180.05 and the highest bid is obviously still 180.02 (because the previous order was a 'market order'). A limited buy order for 12,000 shares with a price limit of 180.04 gets the first two fills just like the market order: 1,100 shares at 180.03 and 9,700 at 180.04. However, the remainder of the order will establish a new bid price level for 1,200 shares at 180.04. It is possible to enter an unlimited buy order that exhausts the book. However, such a trade would often be considered a mis-trade and either (i) be cancelled by the broker, (ii) be cancelled or undone by the exchange, or (iii) hit the maximum price move a stock is allowed per day (\"\"limit up\"\"). Funds and banks often have to buy or sell large quantities, just like you have described. However they usually do not punch through order book levels as I described before. Instead they would spread out the order over time and buy a smaller quantity several times throughout the day. Simple algorithms attempt to get a price close to the time-weighted average price (TWAP) or volume-weighted average price (VWAP) and would buy a smaller amount every N minutes. Despite splitting the order into smaller pieces the price usually moves against the trader for many reasons. There are many models to estimate the market impact of an order before executing it and many brokers have their own model, for example Deutsche Bank. There is considerable research on \"\"market impact\"\" if you are interested. I understand the general principal that when significant buy orders comes in relative to the sell orders price goes up and when a significant sell order comes in relative to buy orders it goes down. I consider this statement wrong or at least misleading. First, stocks can jump in price without or with very little volume. Consider a company that releases a negative earnings surprise over night. On the next day the stock may open 20% lower without any orders having matched for any price in between. The price moved because the perception of the stocks value changed, not because of buy or sell pressure. Second, buy and sell pressure have an effect on the price because of the underlying reason, and not necessarily/only because of the mechanics of the market. Assume you were prepared to sell HyperNanoTech stock, but suddenly there's a lot of buzz and your colleagues are talking about buying it. Would you still sell it for the same price? I wouldn't. I would try to find out how much they are prepared to buy it for. In other words, buy pressure can be the consequence of successful marketing of the stock and the marketing buzz is what changes the price.\"", "title": "" }, { "docid": "401598", "text": "\"My broker offers the following types of sell orders: I have a strategy to sell-half of my position once the accrued value has doubled.

Ideally what happens is that the stock keeps going up, and the trailing stop % keeps following it, and that goes on long enough that accrued dividends end up paying for the stock. What happens in reality is that the stock goes up some, goes down some, then the order gets cancelled because the company announces dividends or something dumb like that.

That being said, no matter how many share you buy, there's no way to know what the impact on the price will be, because that's only one factor in how shares are priced. If anyone could figure out the answer to your question then they'd be extremely rich, because they'd simply watch for big share trades and then buy those stocks on the way up. The market makers who actually execute the trades are the ones who set the prices, and most stocks have multiple market makers trading the stock, so the bid/ask you see is the highest bid and lowest ask. The market makers set the price based on what the trend of the stock is. If, for instance, there's a large number of sell orders against a stock, the market makers will start dropping the bid prices as they fill execution orders, and as they see buy orders increase, they'll raise ask prices as they fill execution orders. The market makers earn the difference between what they paid to buy someone's stock who was selling and what they get from someone else who buys it. This is a simplified explanation, so pro traders, don't beat me up! (grin) So, basically, it takes quite a bit of share volume in one direction or another to affect a stock's price.

The high volumes are attained through high turnover, the strategy might trade up to 500,000 shares (or 5% of the volume) attaining a 50x turnover. But that brings me back to the original point. In the market microstructure literature market impact generally has been found to scale linearly or even sub-linearly for net volume executed.

If, after the price went to $50/share, all the owners of the stock put in stop-loss orders at $45. Note that the real $10/share \"\"real value\"\" of their stock would never have changed. If the people who thought the stock was worth $50 decided to get out of the market, and nobody else was willing to offer more than $10, that would instantly drop the price to $10. The fact that a million shares of stock have stop-loss orders at $45 wouldn't magically generate buyers for those stocks at that price. Indeed, unchecked stop-loss orders would have the reverse effect, since many people who would have been willing if not eager to buy the stock if it had been available for less than $10/share would instead be trying to sell it below that price. It's too bad people think that the number of shares outstanding times the current market price represents some kind of \"\"meaningful quantity\"\". If the present cash value of all future payouts associated with a share of stock is $10, then someone who buys a share of stock for less than that makes money off the seller; someone who pays more loses money to the seller.

This has had the effect of an immediate stock price bump of around 12% which is to be expected as the value becomes the expected post buyback value. However long term gains will require Zynga to turn around their business. This bump will only be sustainable if they can. If their business continues to decline then its stock price will continue to slide.

There are typically two ways to buy (or sell) a security: With a limit order, you would place a buy for 100 shares at $30-. Then it's easy, in the worst case you will get your 100 shares at $30 each exactly. You may get lucky and have the price fall, then you will pay less than $30. Of course if the price immediately goes up to say $35, nobody will sell at the $30 you want, so your broker will happily sit on his hands and rake in the commission while waiting on what is now a hail Mary ask. With a market order, you have the problem you mention: The ticker says $30, but say after you buy the first 5 shares at $30 the price shoots up and the rest are $32 each - you have now paid on average $31.9 per share. This could happen because there is a limit order for 5 at $30 and 200 at $32 (you would have filled only part of that 200). You would be able to see these in the order book (sometimes shown as bid/ask spread or market depth). However, the order book is not law. Just because there's an ask for 10k shares at $35 each for your $30 X stock, doesn't mean that by the time the price comes up to $35, the offer will still be up. The guy (or algorithm) who put it up may see the price going up and decide he now wants $40 each for his 10k shares. Also, people aren't obligated to put in their order: Maybe there's a trader who intends to trade a large volume when the price hits a certain level, like a limit order, but he elected to not put in a limit order and instead watch the ticker and react in real time. Then you will see a huge order suddenly come in out of nowhere. So while the order book is informative, what you are asking is actually fundamentally impossible to know fully, unless you can read the minds of every interested trader. As others said, in \"\"normal\"\" securities (meaning traded at a major exchange, especially those in the S&P500) you simply can't move the price, the market is too deep. You would need millions of dollars to budge the price, and if you had that much money, you wouldn't be asking here on a QA site, you would have a professional financial advisor (or even a team) that specializes in distributing your large transaction over a longer time to minimize the effect on the market. With crazier stocks, such as OTC and especially worthless penny stocks with market caps of $1 mil or less, what you say is a real problem (you can end up paying multiples of the last ticker if not careful) and you do have to be careful about it. Which is why you shouldn't trade penny stocks unless you know what you're doing (and if you're asking this question here, you don't).\"", "title": "" }, { "docid": "470635", "text": "\"Your logic breaks down because you assume that you are the only market participant on your side of the book and that the participant on the other side of the book has entered a market order. Here's what mostly happens: Large banks and brokerages trading with their own money (we call it proprietary or \"\"prop\"\" trading) will have a number of limit (and other, more exotic) orders sitting on both sides of the trading book waiting to buy or sell at a price that they feel is advantageous. Some of these orders will have sat on the book for many months if not years. These alone are likely to prevent your limit orders executing as they are older so will be hit first even if they aren't at a better price. On more liquid stocks there will also be a number of participants entering market orders on both sides of the book whose orders are matched up before limit orders are matched with any market orders. This means that pairing of market orders, at a better price, will prevent your limit order executing. In many markets high frequency traders looking for arbitrage opportunities (for example) will enter a few thousand orders a minute, some of these will be limit orders just off touch, others will be market orders to be immediately executed. The likelihood that your limit order, being as it is posited way off touch, is hit with all those traders about is minimal. On less liquid stocks there are market makers (large institutional traders) who effectively set the bid and offer prices by being willing to provide liquidity and fill the market orders at a temporary loss to themselves and will, in most cases, have limit orders set to provide this liquidity that will be close to touch. They are paid to do this by the exchange and inter-dealer brokers through their fees structure. They will fill the market orders that would hit your limit if they think that it would provide more liquidity in such a way that it fulfils their obligations. Only if there are no other participants looking to trade on the instrument at a better price than your limit (which, of course they can see unless you enter it into a dark pool) AND there is a market order on the opposite side of the book will your limit order be instantaneously be hit, executed, and move the market price.\"", "title": "" }, { "docid": "507828", "text": "\"I'm adding to @Dilip's basic answer, to cover the additional points in your question. I'll assume you are referring to publicly traded stock options, such as those found on the CBOE, and not an option contract entered into privately between two specific counterparties (e.g. as in an employer stock option plan). Since you are not obligated to exercise a call option you purchased on the market, you don't need to maintain funds on account for possible exercising. You could instead let the option expire, or resell the option, neither of which requires funds available for purchase of the underlying shares. However, should you actually choose to exercise the call option (and usually this is done close to expiration, if at all), you will be required to fund your account much like if you bought the underlying shares in the first place. Call your broker to determine the exact rules and timing for when they need the money for a call-option exercise. And to expand on the idea of \"\"cancelling\"\" an option you purchased: No, you cannot \"\"cancel\"\" an option contract, per se. But, you are permitted to sell the call option to somebody else willing to buy, via the market. When you sell your call option, you'll either make or lose money on the sale – depending on the price of the underlying shares at the time (are they in- or out- of the money?), volatility in the market, and remaining time value. Once you sell, you're back to \"\"no position\"\". That's not the same as \"\"cancelled\"\", but you are out of the trade, whether at profit or loss. Furthermore, the option writer (i.e. the seller who \"\"sold to open\"\" a position, in writing the call in the first place) is also not permitted to cancel the option he wrote. However, the option writer is permitted to close out the original short position by simply buying back a matching call option on the market. Again, this would occur at either profit or loss based on market prices at the time. This second kind of buy order – i.e. made by someone who initially wrote a call option – is called a \"\"buy to close\"\", meaning the purchase of an offsetting position. (The other kind of buy is the \"\"buy to open\"\".) Then, consider: Since an option buyer is free to re-sell the option purchased, and since an option writer (who \"\"sold to open\"\" the new contract) is also free to buy back an offsetting option, a process known as clearing is required to match remaining buyers exercising the call options held with the remaining option writers having open short positions for the contract. For CBOE options, this clearing is performed by the Options Clearing Corporation. Here's how it works (see here): What is the OCC? The Options Clearing Corporation is the sole issuer of all securities options listed at the CBOE, four other U.S. stock exchanges and the National Association of Securities Dealers, Inc. (NASD), and is the entity through which all CBOE option transactions are ultimately cleared. As the issuer of all options, OCC essentially takes the opposite side of every option traded. Because OCC basically becomes the buyer for every seller and the seller for every buyer, it allows options traders to buy and sell in a secondary market without having to find the original opposite party. [...]   [emphasis above is mine] When a call option writer must deliver shares to a call option buyer exercising a call, it's called assignment. (I have been assigned before, and it isn't pleasant to see a position called away that otherwise would have been very profitable if the call weren't written in the first place!) Also, re: \"\"I know my counter party cannot sell his shares\"\" ... that's not strictly true. You are thinking of a covered call. But, an option writer doesn't necessarily need to own the underlying shares. Look up Naked call (Wikipedia). Naked calls aren't frequently undertaken because a naked call \"\"is one of the riskiest options strategies because it carries unlimited risk\"\".

However, a perception exists that vegetarian diets are deficient in certain nutrients. OBJECTIVE: To compare dietary quality of vegetarians, nonvegetarians, and dieters, and to test the hypothesis that a vegetarian diet would not compromise nutrient intake when used to manage body weight. DESIGN: Cross-sectional analysis of National Health and Nutrition Examination Survey (1999-2004) dietary and anthropometric data. Diet quality was determined using United States Department of Agriculture's Healthy Eating Index 2005. Participants included adults aged 19 years and older, excluding pregnant and lactating women (N = 13,292). Lacto-ovo vegetarian diets were portrayed by intakes of participants who did not eat meat, poultry, or fish on the day of the survey (n = 851). Weight-loss diets were portrayed by intakes of participants who consumed 500 kcal less than their estimated energy requirements (n = 4,635). Mean nutrient intakes and body mass indexes were adjusted for energy, sex, and ethnicity. Using analysis of variance, all vegetarians were compared to all nonvegetarians, dieting vegetarians to dieting nonvegetarians, and nondieting vegetarians to nondieting nonvegetarians. RESULTS: Mean intakes of fiber, vitamins A, C, and E, thiamin, riboflavin, folate, calcium, magnesium, and iron were higher for all vegetarians than for all nonvegetarians. Although vegetarian intakes of vitamin E, vitamin A, and magnesium exceeded that of nonvegetarians (8.3 ± 0.3 vs 7.0 ± 0.1 mg; 718 ± 28 vs 603 ± 10 μg; 322 ± 5 vs 281 ± 2 mg), both groups had intakes that were less than desired. The Healthy Eating Index score did not differ for all vegetarians compared to all nonvegetarians (50.5 ± 0.88 vs 50.1 ± 0.33, P = 0.6). CONCLUSIONS: These findings suggest that vegetarian diets are nutrient dense, consistent with dietary guidelines, and could be recommended for weight management without compromising diet quality.

Coinciding with the decreased mortality from coronary artery disease, there is evidence pointing toward a significant decrease in rates of sudden cardiac death in the US during the second half of the twentieth century. However the alarming rise in prevalence of obesity and diabetes in the first decade of the new millennium both in the US and worldwide, would indicate that this favorable trend is unlikely to persist. We are likely to witness a resurgence of coronary artery disease and heart failure, as a result of which sudden cardiac death will have to be confronted as a shared and indiscriminate, worldwide public health problem.

STUDY SELECTION: Randomized clinical trials evaluating the effect of omega-3 on all-cause mortality, cardiac death, sudden death, myocardial infarction, and stroke. DATA EXTRACTION: Descriptive and quantitative information was extracted; absolute and relative risk (RR) estimates were synthesized under a random-effects model. Heterogeneity was assessed using the Q statistic and I2. Subgroup analyses were performed for the presence of blinding, the prevention settings, and patients with implantable cardioverter-defibrillators, and meta-regression analyses were performed for the omega-3 dose.

METHODS: In total, 368 children aged 3-5 years were randomly selected from kindergartens in Hong Kong. Constipation was confirmed by Rome-criteria. Children with normal bowel habits served as non-constipated controls. Consumption of vegetables, fruits, whole-grain cereals and fluid were determined using a 3-day food record. RESULTS: A total of 28.8% children were reported to have constipation. Median dietary fibre intake of constipated children was significantly lower than non-constipated children (3.4 g/d (inter-quartile range (IQR): 2.3-4.6 g/d) vs. 3.8 g/d (IQR: 2.7-4.9 g/d); P = 0.044) corresponding to 40% reference dietary fibre intake.

Highest NRF scores per dollar were obtained for sweet potatoes, white potatoes, tomato juices and tomato soups, carrots, and broccoli. Tomato sauces, raw tomatoes, and potato chips were eaten more frequently than were many other vegetables that were both more affordable and more nutrient-rich. These new measures of affordable nutrition can help foodservice and health professionals identify those vegetables that provide the highest nutrient density per unit cost. Processed vegetables, including soups and juices, can contribute to the quality and the affordability of the diet. Copyright © 2013 Academy of Nutrition and Dietetics. Published by Elsevier Inc.

This is attributed to the great diversity of healthy phytochemicals present in these foods. The most investigated physiological effects have been their antioxidant, anti-carcinogenic, hypolipidemic, and hypoglycemic properties. Although less studied in humans, some compounds were very early on shown to be lipotropic in animals, i.e., the capacity to hasten the removal of fat from liver and/or reduce hepatic lipid synthesis or deposits by mainly increasing phospholipid synthesis via the transmethylation pathway for triglyceride-rich lipoprotein exportation from the liver and enhanced fatty acid β-oxidation and/or down- and up-regulation of genes involved in lipogenic and fatty acid oxidation enzyme synthesis, respectively. The main plant lipotropes are choline, betaine, myo-inositol, methionine, and carnitine. Magnesium, niacin, pantothenate, and folates also indirectly support the overall lipotropic effect. The exhaustive review of rat studies investigating phytochemical effect on hepatic lipid metabolism suggests that some fatty acids, acetic acid, melatonin, phytic acid, some fiber compounds, oligofructose, resistant starch, some phenolic acids, flavonoids, lignans, stilbenes, curcumin, saponins, coumarin, some plant extracts, and some solid foods may be lipotropic.

DESIGN: A randomized controlled factorial trial. SETTING: Male patients of general practitioners in south Wales. SUBJECTS: A total of 3114 men under 70 y of age with angina. INTERVENTIONS: Subjects were randomly allocated to four groups: (1) advised to eat two portions of oily fish each week, or to take three fish oil capsules daily; (2) advised to eat more fruit, vegetables and oats; (3) given both the above types of advice; and (4) given no specific dietary advice. Mortality was ascertained after 3-9 y. RESULTS: Compliance was better with the fish advice than with the fruit advice. All-cause mortality was not reduced by either form of advice, and no other effects were attributable to fruit advice. Risk of cardiac death was higher among subjects advised to take oily fish than among those not so advised; the adjusted hazard ratio was 1.26 (95% confidence interval 1.00, 1.58; P=0.047), and even greater for sudden cardiac death (1.54; 95% CI 1.06, 2.23; P=0.025). The excess risk was largely located among the subgroup given fish oil capsules. There was no evidence that it was due to interactions with medication. CONCLUSIONS: Advice to eat more fruit was poorly complied with and had no detectable effect on mortality. Men advised to eat oily fish, and particularly those supplied with fish oil capsules, had a higher risk of cardiac death.

Among lifestyle factors, diet plays a key role in the prevention and control of high BP. Therefore, it is important to elucidate which dietary components can exert beneficial effects on BP through modulation of endothelial function (EF) or by other mechanisms. In this paper we review the role of nutrients, foods, particularly nuts, and dietary patterns on BP control. DATA SYNTHESIS: Because nuts are low in sodium and contain significant amounts of mono- and polyunsaturated fatty acids, fiber, minerals such as magnesium, potassium and calcium, and antioxidants, they have been suggested as potentially protective foods against hypertension. Limited evidence from prospective studies and clinical trials suggests that nut consumption has a beneficial effect on both BP and EF. However, BP changes were a secondary outcome in nut feeding trials and no study used ambulatory BP monitoring as the standard for BP measurements. CONCLUSIONS: Further clinical trials, ideally using ambulatory BP monitoring, are needed to establish the potential protective effect of nut consumption on hypertension and vascular reactivity.

Diagnoses and deaths from cancer at a specific site were confirmed by use of hospital reports and the National Death Index. Cox proportional hazards regression models were used to assess hazard ratios (represented as relative risks [RRs]) of common cancers associated with use of antioxidants, either individually or in combination. Subgroup analyses were conducted to determine if duration of use modified the association of supplement use with cancer risk. All statistical tests were two-sided. Results During an average 9.4 years of treatment, 624 women developed incident invasive cancer and 176 women died from cancer. There were no statistically significant effects of use of any antioxidant on total cancer incidence.

This report summarizes 2010 surveillance data and describes trends since 1996. RESULTS: A total of 19,089 infections, 4,247 hospitalizations, and 68 deaths were reported from FoodNet sites in 2010. Salmonella infection was the most common infection reported (17.6 illnesses per 100,000 persons) and was associated with the largest number of hospitalizations (2,290) and deaths (29); no significant change in incidence of Salmonella infection has occurred since the start of surveillance during 1996-1998. Shiga toxin-producing Escherichia coli (STEC) O157 infection caused 0.9 illnesses per 100,000. Compared with 1996-1998, overall incidence of infection with six key pathogens in 2010 was 23% lower, and pathogen-specific incidence was lower for Campylobacter, Listeria, STEC O157, Shigella, and Yersinia infection but higher for Vibrio infection. Compared with a more recent period, 2006--2008, incidence in 2010 was lower for STEC O157 and Shigella infection but higher for Vibrio infection. CONCLUSIONS: The incidence of STEC O157 infection has declined to reach the 2010 national health objective target of ≥1 case per 100,000. This success, as well as marked declines since 1996-1998 in overall incidence of six key foodborne infections, demonstrates the feasibility of preventing foodborne illnesses. IMPLICATIONS FOR PUBLIC HEALTH PRACTICE: Salmonella infection should be targeted because it has not declined significantly in more than a decade, and other data indicate that it is one of the most common foodborne infections, resulting in an estimated $365 million in direct medical costs annually. The prevention measures that reduced STEC O157 infection need to be applied more broadly to reduce Salmonella and other infections.

The terms are connected to views on the appropriate scope of the encyclopedia , and the appropriate point for a topic to be allowed to `` include '' an encyclopedia article ( i.e. , `` inclusion '' ) or `` delete '' the article ( i.e. , `` deletion '' ) . Inclusionism and deletionism are broad terms falling within a spectrum of views . The concepts are closely related to Wikipedia 's concept of notability , with deletionists and inclusionists taking a strong or relaxed stance on `` notability '' respectively . Many users do not identify strongly with either position . `` Deletionists '' are proponents of selective coverage and removal of articles seen as unnecessary or highly substandard . Deletionist viewpoints are commonly motivated by a desire that Wikipedia be focused on and cover significant topics -- along with the desire to place a firm cap upon proliferation of promotional use ( seen as abuse of the website ) , trivia , and articles which are , in their opinion , of no general interest , lack suitable source material for high quality coverage , or are too short or otherwise unacceptably poor in quality . `` Inclusionists '' are proponents of broad retention , including retention of `` harmless '' articles and articles otherwise deemed substandard to allow for future improvement . Inclusionist viewpoints are commonly motivated by a desire to keep Wikipedia broad in coverage with a much lower entry barrier for topics covered -- along with the belief that it is impossible to tell what knowledge might be `` useful '' or productive , that content often starts poor and is improved if time is allowed , that there is effectively no incremental cost of coverage , that arbitrary lines in the sand are unhelpful and may prove divisive , and that goodwill requires avoiding arbitrary deletion of others ' work . Some extend this to include allowing a wider range of sources such as notable blogs and other websites . To the extent that an official stance exists at 2010 , it is that `` There is no practical limit to the number of topics it can cover '' but `` there is an important distinction between what can be done , and what should be done '' , the latter being the subject of the policy `` What Wikipedia is not '' .

Local authorities , acting within the limits of the law , are to be able to regulate and manage a substantial share of public affairs under their own responsibility in the interests of the local population . The Charter considers that public responsibilities should be exercised preferably by the authorities closest to the citizens , a higher level being considered only when the co-ordination or discharge of duties is impossible or less efficient at the level immediately below . To this end , the Charter sets out the principles concerning the protection of local authorities ' boundaries , the existence of adequate administrative structures and resources for the carrying out of their tasks , the conditions under which responsibilities are to be exercised , the financial resources of local authorities and the legal protection of local self-government . It limits the administrative supervision of local authorities ' activities to the verification of lawfulness only . The principles of local self-government contained in the Charter apply to all categories of local authorities .
