    The Energy Information Administration (EIA) of the US Department of Energy (DOE) is mandated by Congress to be the agency that collects, analyzes, and disseminates impartial, comprehensive data about energy including the volume consumed, its customers, and the purposes for which it is used. The Federal Buildings Supplemental Survey (FBSS) was conducted by EIA in conjunction with DOE`s Office of Federal Energy Management Programs (OFEMP) to gain a better understanding of how Federal buildings use energy. This report presents the data from 881 completed telephone interviews with Federal buildings in three Federal regions. These buildings were systematically selected using OFEMP`s specifications; therefore, these data do not statistically represent all Federal buildings in the country. The purpose of the FBSS was threefold: (1) to understand the characteristics of Federal buildings and their energy use; (2) to provide a baseline in these three Federal regions to measure future energy use in Federal buildings as required in EPACT; and (3) to compare building characteristics and energy use with the data collected in the CBECS.

    It is usually acknowledged that high‐dose vitamin A supplementation (VAS) provides no sustained improvement in vitamin A status, and that the effect of VAS on mortality is more likely linked to its immunomodulating effects. Nonetheless, it is widely assumed that we can deduce something about...

    In recent years, the increase of the consumption of supplements reveals problems concerning the safety of use. Current legislation states that supplements must be free of any therapeutic purpose and must have quality guarantees for the users' safety. The operators of the of Hygiene, Food and Nutrition Service (SIAN) of ASL TO 3 (province of Turin) conducted a surveillance in order to asses the situation on the territory, to know the use and consumption in local gyms. During the official control at the manufacturers / packers of supplements, located on the territory of the ASL TO 3, labels of supplement produced / packed were acquired, to analyze the components indicated, to carry out a deep evaluation of the individual product . Updating of the register of companies located in the territory of the ASL TO 3 was carried out; and during the period October 2011-March 2013 the labels of the products of these companies have been found and analyzed. The detailed content of the labels (ingredients, dose, method of recruitment, composition, etc. ..) was written in a database. It was also checked how many local gyms marketed supplements, and, in a small sample, a questionnaire was administered to visitors, in order to assess consumption. 355 labels were acquired and loaded on the database. 80% of them falls within the category of supplements based on ingredients derived from plants or similar. For these products was evaluated the presence on the label of not allowed plant extracts (according to the Ministerial Decree of 9 July 2012): only 2 products (of the same company) contained an ingredient not allowed. In all the examined labels was evaluated the presence of the substances for which there are specific warnings: 97% of the label is compliant and 3% are not in compliance. In the analyzed products the indications for use mainly found on the labels are related to increased demand and/or reduced intake, followed by antioxidant action. The study also evaluated the sale of

    The increasing availability of food supplements, aggressive media advertising, and common beliefs that these substances have only positive effects on health and sport performance indicate a need for continuous monitoring of this phenomenon. The aim of this study was to investigate the habits and beliefs related to diet supplementation among medical, health professional, and other university/high school students by means of a cross-sectional anonymous survey online. Among the respondents aware of supplements, 37.4% were taking or had taken them in the past. Food supplement use was more common among university students (in particular, those in health professional graduate courses) than high school students. Individual sport practice, rather than team sport, was associated with higher likelihood of food supplement use. Multivitamins were most commonly used, while weight-loss formulations were the least popular. Strikingly, filling nutrient gaps was statistically not considered the main reason for taking food supplements. Instead, they were used to enhance mental performance or enhance well-being. There was statistical evidence that students not enrolled in health or medical professional studies strongly agreed more often than medical students that taking food supplements prevents illness. These results indicate a striking difference between the evidence-based and personal reasons for food supplement use. Arguably, it calls for an improvement in education about diet supplementation and a change in attitude of health care providers to its implementation.

    Concentrations of 134 Cs, 137 Cs and 40 K in 73 supplements marked in Japan were measured by gamma-ray spectrometry. In all supplements, 134 Cs was not detected. On the other hand, 134 Cs was detected in 9 supplements, and the concentrations of 137 Cs in them were in the range of 2.3-190 Bq/kg. There was a tendency that concentrations of 137 Cs in supplements made from materials accumulating 137 Cs, such as mushrooms and blueberries, were high. Furthermore, 40 K was detected in 56 supplements at levels of 17.6-11600 Bq/kg. The committed effective dose of 137 Cs in adults by annually taking supplements was estimated to be about 2.9 μSv.

    Inverse correlations have been found in most studies on the relationship between dietary intake and plasma concentrations of carotenoids on one side and degenerative diseases such as cancer and cardiovascular diseases on the other side. Protective effects of carotenoids have been found for pathologies of the retina and the skin. Concentrations of these molecules in blood are lower in digestive pathologies and HIV. Short- and long-term toxicity of carotenoids was found to be low. In combination with the beneficial effects found for diets rich in carotenoids, this has initiated trials with relatively high doses of carotenoid supplements. In the study in Linxian (China) in a rural population with poor nutritional status, supplementation with beta-carotene, zinc, selenium and vitamin E lowered total mortality and mortality from stomach cancer. Other studies (ATBC, Caret.) on well-fed subjects did not show beneficial effects on mortality from cancer and cardiovascular diseases. On the contrary, higher mortality and lung cancer incidence was found in supplemented subjects that were also exposed to asbestos and cigarette smoke. In these studies, doses of supplemental beta-carotene were high and varied from 20 to 50 mg/day. One still ongoing study, called Suvimax, doses subjects for eight years with a cocktail of vitamins and minerals including 6 mg per day of beta-carotene. This supplementation with physiologically seen more "normal" doses might give clarity on the question if beta-carotene is the protective factor in fruits and vegetables.

    Consumer usage of dietary supplements is prevalent in the United States, and total usage is higher than reported in recent National Health and Nutrition Examination Surveys (NHANES), because these surveys capture usage only in the 30 days prior to the respondent's interview and do not capture occasional and seasonal use throughout the year. We report data from a series of consumer surveys on the full extent of dietary supplement use, on the reasons for supplement use, and on the products most commonly taken, as well as other health habits of supplement users. The Council for Responsible Nutrition (CRN), a trade association of the dietary supplement industry, has contracted with Ipsos Public Affairs to conduct consumer surveys annually since 2000. The surveys have been administered online since 2007 to about 2000 subjects each year. We report 5 years of data (2007 to 2011) on the prevalence of dietary supplement use, as well as more detailed data from the 2011 survey on the products used, the reasons for using supplements, and other health habits of supplement users. The prevalence of supplement use fluctuated within the range of 64% to 69% from 2007 to 2011, and the prevalence of regular supplement use ranged from 48% to 53%, with no statistically significant differences from year to year. Over the 5-year period, the percentage of respondents who said that they regularly used a variety of supplements increased from 28% to 36%, and the increase from 2010 to 2011 was statistically significant. The percentage of respondents who said that they regularly used only a multivitamin, as opposed to a variety of supplements, declined from 24% to 17%, and the decrease from 2007 to 2008 was statistically significant. Detailed results from the 2011 survey confirm that supplement use increases with age and is higher in women than in men. Vitamin or mineral supplements were used by 67% of all respondents in 2011, specialty supplements by 35%, botanicals by 23%, and sports

    Full Text Available Although dietary supplement use is common, its assessment is challenging, especially among ethnic minority populations such as Hispanics/Latinos. Using the Hispanic Community Health Study/Study of Latinos (HCHS/SOL (n = 16,415, this report compares two strategies for capturing dietary supplement use over a 30-day period: a medication-based inventory and a nutrition-based dietary supplement interview. Age-standardized prevalence was calculated across multiple dietary supplement definitions, adjusted with survey/nonresponse weights. The prevalence of dietary supplement use was substantially higher as measured in the dietary supplement interview, compared to the medication inventory: for total dietary supplements (39% vs 26%, respectively, for nonvitamin, nonmineral supplements (24% vs 12%, and for botanicals (9.2% vs 4.5%. Concordance between the two assessments was fair to moderate (Cohen's kappa: 0.31–0.52. Among women, inclusion of botanical teas increased the prevalence of botanical supplement use from 7% to 15%. Supplement assessment that includes queries about botanical teas yields more information about patient supplement use.

    Full Text Available Abstract Background Although Autistic Disorder is associated with several congenital conditions, the cause for most cases is unknown. The present study was undertaken to determine whether breastfeeding or the use of infant formula supplemented with docosahexaenoic acid and arachidonic acid is associated with Autistic Disorder. The hypothesis is that breastfeeding and use of infant formula supplemented with docosahexaenoic acid/arachidonic acid are protective for Autistic Disorder. Methods This is a case-control study using data from the Autism Internet Research Survey, an online parental survey conducted from February to April 2005 with results for 861 children with Autistic Disorder and 123 control children. The analyses were performed using logistic regression. Results Absence of breastfeeding when compared to breastfeeding for more than six months was significantly associated with an increase in the odds of having autistic disorder when all cases were considered (OR 2.48, 95% CI 1.42, 4.35 and after limiting cases to children with regression in development (OR 1.95, 95% CI 1.01, 3.78. Use of infant formula without docosahexaenoic acid and arachidonic acid supplementation versus exclusive breastfeeding was associated with a significant increase in the odds of autistic disorder when all cases were considered (OR 4.41, 95% CI 1.24, 15.7 and after limiting cases to children with regression in development (OR 12.96, 95% CI 1.27, 132. Conclusion The results of this preliminary study indicate that children who were not breastfed or were fed infant formula without docosahexaenoic acid/arachidonic acid supplementation were significantly more likely to have autistic disorder.

    The current design of the Salt Waste Processing Facility (SWPF) includes an auxiliary facility, the Actinide Finishing Facility, which provides a second contact of monosodium titanate (MST) to remove soluble actinides and strontium from waste if needed. This treatment will occur after cesium removal by Caustic-Side Solvent Extraction (CSSX). Although the process changes and safety basis implications have not yet been analyzed, provisions also exist to recover the MST from this operation and return to the initial actinide removal step in the SWPF for an additional (third) contact with fresh waste. A U.S. Department of Energy (DOE) request identified the need to study the following issues involving this application of MST: Determine the effect of organics from the solvent extraction (CSSX) process on radionuclide sorption by MST; Determine the efficiency of re-using MST for multiple contacts; and Examine fissile loading on MST under conditions using a waste containing significantly elevated concentrations of plutonium, uranium, neptunium, and strontium. This report describes the results of three experimental studies conducted to address these needs: (1) Addition of high concentrations of entrained CSSX solvent had no noticeable effect, over a two week period, on the sorption of the actinides and strontium by MST in a direct comparison experiment. (2) Test results show that MST still retains appreciable capacity after being used once. For instance, reused MST--in the presence of entrained solvent--continued to sorb actinides and strontium. (3) A single batch of MST was used to sequentially contact five volumes of a simulant solution containing elevated concentrations of the radionuclides of interest. After the five contacts, we measured the following solution actinide loadings on the MST: plutonium: 0.884 ± 0.00539 wt % or (1.02 ± 0.0112) E+04 (micro)g/g MST, uranium: 12.1 ± 0.786 wt % or (1.40 ± 0.104) E+05 (micro)g/g MST, and neptunium: 0.426 ± 0.00406 wt % or

    U.S. nutrition surveys find that intakes of many nutrients fall short of recommendations. The majority of U.S. adults use multivitamins and other dietary supplements as one means of improving nutrient intakes. Some policy makers and health professionals appear reluctant to recommend routine use of dietary supplements to fill nutrient gaps in the diet, in part because they are concerned that people will view the supplements as a substitute for dietary improvement and that the use of supplements may lead to overconsumption of micronutrients. Surveys find that in fact users of dietary supplements tend to have better diets and adopt other healthy habits, suggesting that the supplements are viewed as one aspect of an overall effort to improve wellness. Furthermore, evidence demonstrates that the incidence of excess micronutrient intake is low. We report the results of a survey probing consumer attitudes about the role of dietary supplements. The Council for Responsible Nutrition funded a survey to measure consumer attitudes about the role of multivitamins, calcium and/or vitamin D supplements, and other supplements in improving dietary intakes. The research was designed and analyzed by FoodMinds and was fielded using Toluna's On-line Omnibus. The weighted sample of 2159 respondents is representative of U.S. adults. Nearly 90% of the survey respondents agreed that multivitamins and supplements of calcium and/or vitamin D can help meet nutrient needs when desirable intakes are not achieved through food alone. At the same time, 80% agreed that dietary supplements should not be used to replace healthy dietary or lifestyle habits, and 82% agreed that people considering taking a high dose, single nutrient supplement should talk with their physician. These results provide additional support for the conclusion that the vast majority of consumers recognize that multivitamins and other supplements can help fill nutrient gaps but should not be viewed as replacements for a healthy

    Full Text Available Background. In 1990s, complementary and alternative medicine (CAM, including use of herbs and supplements, gained popularity in the United States. However, more recent surveys suggest that demand for herbs and supplements has stabilized. Objective. This study examined the prevalence, patterns, and changes in herb and supplement use among the US adults, using the 2002, 2007, and 2012 National Health Interview Surveys (NHIS. Methods. Weighted population estimates were derived from three complementary and alternative medicine supplements to the NHIS. Prevalence rates for herb and supplement use were compared, using Wald chi-square tests to measure changes between years. Results. An estimated 40.6 million US adults reported herb and supplement use in 2012. However, the rate of herb and supplement use dropped from 18.9% in 2002 to 17.9% in 2007 and 2012 (P<0.05. This decline in use was more pronounced among women, racial or ethnic minorities, and adults with low incomes. Conclusion. Herb and supplements use remains common in the USA, but adult use rates are on the decline. It is still important for health care providers to ask patients about herb and supplement use.

    Full Text Available Although intake of multivitamin supplements is becoming increasingly popular, the relationship between intake of multivitamin supplements and incident asthma remains unclear. Prospective studies in adults with long-term follow-up are especially scarce. Our objective was to investigate the association between intake of multivitamin supplements and asthma development in Norwegian adults. We followed 16 952 adult subjects from the second survey of the Nord-Trøndelag Health Study (1995–1997 up to 2006–2008, who, at baseline, were free of asthma and provided information on their intake of multivitamin supplements and cod liver oil. Regular intake of multivitamin supplements or cod liver oil was defined as daily intake for ≥3 months during the year prior to baseline. Incident asthma was defined as reported new-onset asthma after the 11-year follow-up. Intake of multivitamin supplements only was associated with an increased odds ratio for incident asthma (OR 1.55, 95% CI 1.12–2.13 after adjustment for a number of common confounding factors (model I. Similar odds ratios were found for intake of cod liver oil only and for intake of both supplements (1.59 and 1.73, respectively. Regular intake of multivitamin supplements was associated with an increased odds ratio for incident asthma in Norwegian adults.

    As part of a settlement agreement for nuclear waste incidents in 2014, several supplemental environment projects (SEPs) were initiated at Los Alamos National Laboratory (LANL or the Laboratory) between the U.S. Department of Energy and the state of New Mexico. One SEP from this agreement consists of performing aquatic life surveys and will be used to assess the applicability of using generic ambient water-quality criteria (AWQC) for aquatic life. AWQC are generic criteria developed by the U.S. Environmental Protection Agency (EPA) to cover a broad range of aquatic species and are not unique to a specific region or state. AWQC are established by a composition of toxicity data, called species sensitivity distributions (SSDs), and are determined by LC50 (lethal concentration of 50% of the organisms studied) acute toxicity experiments for chemicals of interest. It is of interest to determine whether aquatic species inhabiting waters on the Pajarito Plateau are adequately protected using the current generic AWQC. The focus of this study will determine which aquatic species are present in ephemeral, intermittent, and perennial waters within LANL boundaries and from reference waters adjacent to LANL. If the species identified from these waters do not generally represent species used in the SSDs, then SSDs may need to be modified and AWQC may need to be updated. This sampling and analysis plan details the sampling methodology, surveillance locations, temporal scheduling, and analytical approaches that will be used to complete aquatic life surveys. A significant portion of this sampling and analysis plan was formalized by referring to Appendix E: SEP Aquatic Life Surveys DQO (Data Quality Objectives).

    The use of food supplements by the general public is poorly quantified, and little information on this subject is available in the medical literature. We surveyed 12 recent issues of popular health and bodybuilding magazines (1) to quantify the number of advertisements for food supplements, the number of products advertised, and the number and type of ingredients in these products; (2) to identify the purported health benefits of these products; and (3) as a preliminary effort to identify areas for future research. We counted 89 brands, 311 products, and 235 unique ingredients, the most frequent of which were unspecified amino acids; the most frequently promoted health benefit was muscle growth. We also found many unusual or unidentifiable ingredients, and 22.2% of the products had no ingredients listed in their advertisements. Health professionals may not be aware of how popular food supplements are or of a particular supplement's potential effects or side effects. In addition, patients may be reluctant to discuss their use of these products with traditional medical practitioners. We recommend that routine history taking include specific questions about patients' use of food supplements and that any possible adverse effects or side effects be reported to public health authorities.

    Past national surveys indicate that use of herbs and dietary supplements rose rapidly in the United States during the 1990s and early 2000s. Additional research is needed to determine whether this growth rate and associated patterns of use have persisted over time. The objectives of this study were: (1) to assess population and subpopulation changes in rates of herb and supplement use; and (2) to assess changes in rates of disclosure of herb and supplement use to conventional medical providers. This study used data from the 2002 (n = 30,427) and 2007 (n = 22,657) Adult Complementary and Alternative Medicine File to the National Health Interview Survey (NHIS). Weighted group and subgroup comparisons used the Wald χ(2) tests to compare differences in herb and supplement use between 2002 and 2007. The number of adults in the United States that ever used herbs or supplements grew slightly, from 50.6 million in 2002 to 55.1 million in 2007. However, the proportion of adults who reported use of herbs or supplements in the past 12 months dropped significantly: from 18.9% in 2002 to 17.9% in 2007 (P minorities also reported a significant decline in recent use. The proportion of respondents that disclosed herb or supplement use to their physician or another conventional medical professional rose, from 33.4% in 2002 to 45.4% in 2007. However, <1% of recent herb and supplement users disclosed this use to their pharmacist. Limitations of this research are that the 2 national data sets were not directly comparable and that questionnaires in the 2 surveys assessed were not identical. Herbal preparations and dietary supplements remain popular in the United States, but the user population and patterns of use are changing. Ongoing surveillance of this health behavior is a public health priority. Copyright © 2011 Elsevier HS Journals, Inc. All rights reserved.

    In 1991, the Idaho Supplementation Studies (ISS) project was implemented to address critical uncertainties associated with hatchery supplementation of chinook salmon Oncorhynchus tshawytscha populations in Idaho. The project was designed to address questions identified in the Supplementation Technical Work Group (STWG) Five-Year-Workplan (STWG 1988). Two goals of the project were identified: (1) assess the use of hatchery chinook salmon to increase natural populations in the Salmon and Clearwater river drainages, and (2) evaluate the genetic and ecological impacts of hatchery chinook salmon on naturally reproducing chinook salmon populations. Four objectives to achieve these goals were developed: (1) monitor and evaluate the effects of supplementation on presmolt and smolt numbers and spawning escapements of naturally produced fish; (2) monitor and evaluate changes in natural productivity and genetic composition of target and adjacent populations following supplementation; (3) determine which supplementation strategies (broodstock and release stage) provide the quickest and highest response in natural production without adverse effects on productivity; and (4) develop supplementation recommendations. This document reports on the first five years of the long-term portion of the ISS project. Small-scale studies addressing specific hypotheses of the mechanisms of supplementation effects (e.g., competition, dispersal, and behavior) have been completed. Baseline genetic data have also been collected. Because supplementation broodstock development was to occur during the first five years, little evaluation of supplementation is currently possible. Most supplementation adults did not start to return to study streams until 1997. The objectives of this report are to: (1) present baseline data on production and productivity indicators such as adult escapement, redd counts, parr densities, juvenile emigrant estimates, and juvenile survival to Lower Granite Dam (lower Snake

    Background Recently, the number of people interested in health in South Korea has increased, and the rate of dietary supplement use is rising. Researchers have hypothesized that the rate of practicing healthy habits is higher among those who use dietary supplements than those who do not. Therefore, this study aimed to discover the association between taking dietary supplements and practicing various healthy habits in the Korean, adult population. Methods The sample included 15,789 adults over 19 years old who participated in the fifth Korea National Health and Nutrition Examination Survey. The user group was defined as those taking dietary supplements for more than 2 weeks during the previous year or once during the past month. Measures for the seven healthy habits were based on those included in the Alameda study and were analyzed accounting for the complex sampling design. Results The rate of taking dietary supplements was significantly higher in women, middle aged participants, urban residents, those with a higher income, those with a higher education level, and nonsmokers as well as among women with a moderate subjective health status, women who limited their alcohol content, and women with dyslipidemia. In the adjusted analysis, the rate of performing three of the 'Alameda 7' habits—eating breakfast regularly, restricting snacking, and limiting drinking—was higher in the female dietary supplement user group than in the other groups. Women practiced more healthy habits and had a higher dietary supplement intake rate than men. Conclusion We found that taking dietary supplements in Korean adults is highly associated with demographic and social factors. Taking dietary supplements had a relationship with dietary habits, and there was no significant association between dietary supplement and other healthy habits. Thus in the health clinic, we suggest that taking dietary supplements complements a patient's healthy habits, with the exception of dietary habits, for

    Objectives The objective of the study was to evaluate whether oral cobalamin supplementation can restore normocobal-aminaemia in cats with hypocobalaminaemia and clinical signs of gastrointestinal disease. Methods This was a retrospective study based on a computerised database search for client-owned cats treated at Evidensia Specialist Animal Hospital, Helsingborg, Sweden, during the period December 2013 to August 2016. Inclusion criteria were cats with clinical signs of chronic enteropathy, an initial serum cobalamin concentration ⩽250 pmol/l (reference interval 214-738 pmol/l) and oral treatment with cobalamin tablets. Results Twenty-five cats met the inclusion criteria. The cats were treated with 0.25 mg cyanocobalamin tablets once daily. Serum cobalamin concentration was rechecked 27-94 days after continuous oral cobalamin supplementation. All cats had serum cobalamin concentrations above the reference interval after oral cobalamin supplementation. Median (range) serum cobalamin concentration was 128 pmol/l (111-250 pmol/l) prior to treatment and 2701 pmol/l (738-16,359 pmol/l) after supplementation. This difference was statistically significant ( P cats with hypocobalaminaemia. Thus, oral cobalamin supplementation is a promising alternative to parenteral administration. Prospective comparative studies in cats being treated with parenteral vs oral cobalamin supplementation in a larger number of patients are warranted before oral supplementation can be recommended for routine use.

    Exposure to violence and other forms of potentially traumatic events (PTEs) are common among youths with externalizing psychopathology. These associations likely reflect both heightened risk for the onset of externalizing problems in youth exposed to PTEs and elevated risk for experiencing PTEs among youth with externalizing disorders. In this study, we disaggregate the associations between exposure to PTEs and externalizing disorder onset in a population-representative sample of adolescents. We analyzed data from 13- to 18-year-old participants in the National Comorbidity Survey Replication-Adolescent Supplement (NCS-A) (N = 6,379). Weighted survival models estimated hazard ratios (HRs) for onset of oppositional defiant disorder (ODD), conduct disorder (CD), and substance use disorders (SUDs) associated with PTEs, and for exposure to PTEs associated with prior-onset externalizing disorders. Multiplicative interaction terms tested for effect modification by sex, race/ethnicity, and household income. All types of PTEs were associated with higher risk for SUD (HRs = 1.29-2.21), whereas only interpersonal violence (HR = 2.49) was associated with onset of CD and only among females. No associations were observed for ODD. Conversely, ODD and CD were associated with elevated risk for later exposure to interpersonal violence and other/nondisclosed events (HRs = 1.45-1.75). Externalizing disorders that typically begin in adolescence, including SUDs and CD, are more likely to emerge in adolescents with prior trauma. ODD onset, in contrast, is unrelated to trauma exposure but is associated with elevated risk of experiencing trauma later in development. CD and interpersonal violence exposure exhibit reciprocal associations. These findings have implications for interventions targeting externalizing and trauma-related psychopathology.

    Full Text Available Abstract Background Despite the popular use of vitamin supplements and several prospective cohort studies investigating their effect on cancer incidence and cardiovascular disease (CVD, scientific data supporting their benefits remain controversial. Inconsistent results may be partly explained by the fact that use of supplements is an inconsistent behavior in individuals. We examined whether vitamin supplement use patterns affect cancer and CVD risk in a population-based cohort study in Japan. Methods A total of 28,903 men and 33,726 women in the Japan Public Health Center-based Prospective Study cohort, who answered questions about vitamin supplement use in the first survey from 1990-1994 and the second survey from 1995-1998, were categorized into four groups (never use, past use, recent use, and consistent use and followed to the end of 2006 for cancer and 2005 for CVD. Sex-specific hazard ratios (HRs and 95% confidence intervals (95% CIs were used to describe the relative risks of cancer and CVD associated with vitamin supplement use. Results During follow-up, 4501 cancer and 1858 CVD cases were identified. Multivariate adjusted analysis revealed no association of any pattern of vitamin supplement use with the risk of cancer and CVD in men. In women, consistent use was associated with lower risk of CVD (HR 0.60, 95% CI 0.41-0.89, whereas past (HR 1.17, 95% CI 1.02-1.33 and recent use (HR 1.24, 95% CI 1.01-1.52 were associated with higher risk of cancer. Conclusions To our knowledge, this is the first prospective cohort study to examine simultaneously the associations between vitamin supplement use patterns and risk of cancer and CVD. This prospective cohort study demonstrated that vitamin supplement use has little effect on the risk of cancer or CVD in men. In women, however, consistent vitamin supplement use might reduce the risk of CVD. Elevated risk of cancer associated with past and recent use of vitamin supplements in women may be partly

    Full Text Available Introduction. Folic acid (FA supplementation is recommended worldwide in the periconceptional period for the prevention of neural tube defects. Due to its involvement in a number of cellular processes, its role in other pregnancy outcomes such as miscarriage, recurrent miscarriage, low birth weight, preterm birth (PTB, preeclampsia, abruptio placentae, and stillbirth has been investigated. PTB is a leading cause of perinatal mortality and morbidity; therefore its association with FA supplementation is of major interest. The analysis of a small number of randomized clinical trials (RCTs has not found a beneficial role of FA in reducing the rate of PTBs. Aim of the Study. The aim of this review was to examine the results from recent observational studies about the effect of FA supplementation on PTB. Materials and Methods. We carried out a search on Medline and by manual search of the observational studies from 2009 onwards that analyzed the rate of PTB in patients who received supplementation with FA before and/or throughout pregnancy. Results. The results from recent observational studies suggest a slight reduction of PTBs that is not consistent with the results from RCTs. Further research is needed to better understand the role of FA supplementation before and during pregnancy in PTB.

    Background Dietary supplement use in the United States is prevalent and represents an important source of nutrition. However, little is known about individuals who routinely consume multiple dietary supplements. This study describes the dietary supplement usage patterns, health, and nutritional status of long-term multiple dietary supplement users, and where possible makes comparisons to non-users and multivitamin/mineral supplement users. Methods Using a cross-sectional study design, information was obtained by online questionnaires and physical examination (fasting blood, blood pressure, body weight) from a convenience sample of long-term users of multiple dietary supplements manufactured by Shaklee Corporation (Multiple Supp users, n = 278). Data for non-users (No Supp users, n = 602) and multivitamin/mineral supplement users (Single Supp users, n = 176) were obtained from the National Health and Nutrition Examination Survey (NHANES) 2001–2002 and NHANES III 1988–1994. Logistic regression methods were used to estimate odds ratios with 95% confidence intervals. Results Dietary supplements consumed on a daily basis by more than 50% of Multiple Supp users included a multivitamin/mineral, B-complex, vitamin C, carotenoids, vitamin E, calcium with vitamin D, omega-3 fatty acids, flavonoids, lecithin, alfalfa, coenzyme Q10 with resveratrol, glucosamine, and a herbal immune supplement. The majority of women also consumed gamma linolenic acid and a probiotic supplement, whereas men also consumed zinc, garlic, saw palmetto, and a soy protein supplement. Serum nutrient concentrations generally increased with increasing dietary supplement use. After adjustment for age, gender, income, education and body mass index, greater degree of supplement use was associated with more favorable concentrations of serum homocysteine, C-reactive protein, high-density lipoprotein cholesterol, and triglycerides, as well as lower risk of prevalent elevated blood pressure and diabetes

    This report summarizes brood year 1999 juvenile production and emigration data and adult return information for 2000 for streams studied by the Nez Perce Tribe for the cooperative Idaho Salmon Supplementation Studies in Idaho Rivers (ISS) project. In order to provide inclusive juvenile data for brood year 1999, we include data on parr, presmolt, smolt and yearling captures. Therefore, our reporting period includes juvenile data collected from April 2000 through June 2001 for parr, presmolts, and smolts and through June 2002 for brood year 1999 yearling emigrants. Data presented in this report include; fish outplant data for treatment streams, snorkel and screw trap estimates of juvenile fish abundance, juvenile emigration profiles, juvenile survival estimates to Lower Granite Dam (LGJ), redd counts, and carcass data. There were no brood year 1999 treatments in Legendary Bear or Fishing Creek. As in previous years, snorkeling methods provided highly variable population estimates. Alternatively, rotary screw traps operated in Lake Creek and the Secesh River provided more precise estimates of juvenile abundance by life history type. Juvenile fish emigration in Lake Creek and the Secesh River peaked during July and August. Juveniles produced in this watershed emigrated primarily at age zero, and apparently reared in downstream habitats before detection as age one or older fish at the Snake and Columbia River dams. Over the course of the ISS study, PIT tag data suggest that smolts typically exhibit the highest relative survival to Lower Granite Dam (LGJ) compared to presmolts and parr, although we observed the opposite trend for brood year 1999 juvenile emigrants from the Secesh River. SURPH2 survival estimates for brood year 1999 Lake Creek parr, presmolt, and smolt PIT tag groups to (LGJ) were 27%, 39%, and 49% respectively, and 14%, 12%, and 5% for the Secesh River. In 2000, we counted 41 redds in Legendary Bear Creek, 4 in Fishing Creek, 5 in Slate Creek, 153 in the

    In consideration of the increasing popularity of frankincense and the widely published quality problems associated with botanical dietary supplements, a survey was conducted for the first time on the quality of frankincense containing botanical dietary supplements. Six US products representing 78 % of the units sold and 70 % of the market value, and 11 European products representing 30 % of the units sold and 40 % of the market value were tested for their boswellic acid composition profile, label compliance, and claimed health benefits. Special focus was also set on the statements made with regard to the frankincense applied.Only five products out of seventeen disclosed all relevant information for the Boswellia extract, mentioning the species, the part of plant used, and the boswellic acid content. Whereas all products but one claimed to use Boswellia serrata, three products did not mention the resin as the part applied and 10 products did not declare the boswellic acid content. Apart from the different boswellic acid composition determined with a sensitive LC/MS method, 41 % of the products did not comply with the label declaration. Hence, one product from Italy did not contain any of the six characteristic boswellic acids (KBA, AKBA, αBA, βBA, AαBA, AβBA) at all and another US product contained only traces, suggesting the absence of frankincense or the use of Boswellia frereana instead of B. serrata. In another product, the ratios of the individual boswellic acids were different from B. serrata gum resin, indicating the use of another species such as Boswellia sacra or Boswellia carterii. Furthermore, two products revealed different boswellic acid contents from those declared on the label. Further, two products did not declare the use of manipulated Boswellia gum resin extract being enriched in acetyl-11-keto-boswellic acid content reaching up to 66 %. In addition, consumers could be misled by outdated literature or references to in vitro studies

    Limited cutaneous synthesis due to low sun exposure and inadequate dietary intake makes vitamin D supplementation a necessity for many Canadian children. Identification of the factors associated with supplement use is necessary for public health awareness campaigns, but they have not been identified previously. Therefore, the purpose of this study was to assess the prevalence and the determinants of the use of vitamin D supplements among children in the province of Alberta, Canada. In 2014, a representative sample of grade five students (10-11 y) in Alberta (n = 2686) was surveyed. Data on dietary intake and use of vitamin D supplements were obtained using a modified Harvard Youth/Adolescent Food Frequency questionnaire. Mixed effect multiple logistic regression was employed to identify the key correlates of supplement use. Use of vitamin D supplements by children was 29.45 % although only 11.83 % took supplements daily. Children who resided in a metropolitan area (OR = 1.32; 95 % CI:1.06-1.65), were more physically active (2nd tertile: OR = 1.39; 95 % CI:1.09-1.78 and 3rd tertile: OR = 1.70; 95 % CI:1.33-2.16), or whose parents completed college (OR = 1.35; 95 % CI:1.05-1.74) were more likely to take vitamin D supplements. Prevalence of use was highest among those who had a high vitamin D diet and those with under/normal body weight status, although supplement use was not statistically associated with either dietary vitamin D intake or weight status. A considerable proportion of children did not take vitamin D supplements. Region of residence, physical activity level and parental education were determinants of supplement use, independent of child's gender, household income, weight status and dietary practices. We suggest prioritizing public health efforts to support strategies to make parents aware of the importance of providing the correct dose of vitamin D supplements for their children to meet dietary recommendations.

    Antenatal iron supplementation is a cost effective way of reducing iron deficiency anaemia among pregnant women in resource limited countries like Uganda. Poor adherence to iron supplements has limited its effectiveness in reducing maternal anaemia as evidenced by the high burden of iron deficiency anemia in Sub-saharan Africa. The aim of this study was to determine the level of and factors associated with adherence to iron supplementation among women attending antenatal clinic at Mulago National Referral Hospital, Kampala, Uganda. Three hundred and seventy pregnant women were recruited in a cross sectional survey in Mulago National Referral Hospital antenatal clinic after informed consent between February and April 2014. Levels of adherence to iron supplements were assessed using visual analogue scale and factors associated collected using an interviewer administered questionnaire. About 12% (11.6%) of the mothers attending the antenatal clinic adhered to iron supplements over 30 day period. Mothers who had had four or more antenatal visits prior to the survey [odds ratio (OR) = 1.49, 95% confidence interval (CI) 1.12-1.97], had more than 2 week supply of iron supplements in the previous visit (OR 2.81, 95% CI 1.02-1.09), prior health education (OR 1.56, 95% CI 1.07-2.29) were more likely to adhere to iron supplements. Inadequate drug supplies and fear for side effects were the main reasons why participants missed the iron supplements. There was low adherence to iron supplements among mothers attending antenatal clinic at Mulago National Referral  Hospital. We recommend a national evaluation of adherence to iron supplements and look at ways of increasing adherence.

    Nonfatal injury is common among adolescents in the U.S., but little is known about the bi-directional associations between injury and mental health. Utilizing a nationally representative sample of U.S. adolescents, we examined 1) associations between lifetime mental health history and subsequent injury; 2) concurrent associations between injury and mental health; and 3) associations between injury and subsequent mental disorders. Data were drawn from the National Comorbidity Survey Replication-Adolescent Supplement (NCS-A), a national survey of adolescents aged 13 through 17 years (N = 10,123). Twelve-month prevalence of nonfatal injury requiring medical attention was assessed along with lifetime, 12-month, and 30-day prevalence of DSM-IV depressive, anxiety, behavior, substance use, and bipolar disorders. We used Poisson regression to examine associations between 1) lifetime history of mental disorders and 12-month exposure to injury; 2) concurrent associations between 12-month exposure to injury and 12-month prevalence of mental disorders; and 3) 12-month exposure to injury and 30-day prevalence of mental disorders. A total of 11.6% of adolescents experienced an injury requiring medical attention in the year before the survey. Lifetime history of mental disorders was not associated with past-year injury. Behavior and bipolar disorders were concurrently associated with past-year injury. Past-year injury occurrence predicted increased risk for past-month anxiety disorders and decreased risk of past-month depressive disorders.

    Full Text Available Abstract Background The aim of this study was to assess the frequency of use of dietary supplements (DS among large sample of elite Finnish athletes and to describe possible changes in dietary supplement use between the years 2002 and 2009. Methods A prospective follow-up study was conducted on Olympic athletes. The first survey was conducted on Olympic athletes in 2002 (N = 446 and the follow-up study was conducted between May 2008 and June 2009 (N = 372. Results In 2002, a total of 81% of the athletes used dietary supplements (a mean of 3.37 ± 3.06 DS per user and in 2009, a total of 73% of the athletes (a mean of 2.60 ± 2.69 per DS user used them. After adjusting for age-, sex- and sport type, the OR (95% confidence interval, CI for use of any dietary supplement was significantly less in 2009 as compared with 2002 results (OR, 0.62; 95% CI, 0.43-0.90. Decrease in DS use was observed in all supplement subgroups (vitamins, minerals, nutritional supplements. Athletes in speed and power events and endurance events reported use of any dietary supplement significantly more often than team sport athletes both in 2002 and 2009. In year 2009, the frequency of all dietary supplement use increased when athlete's age increased and the increase was significant in older age groups: of the athletes under 21 years 63%, 21-24 years 83% and over 24 years 90% consumed nutritional supplements. Conclusions Based in our study, there seems to be a lowering trend of dietary supplement use among elite Finnish athletes although differences between sport subgroups and age groups are considerable.

    Hydropower development and operations in the Columbia River basin have caused the loss of 5 million to 11 million salmonids. An interim goal of the Northwest Power Planning Council is to reestablish these historical numbers by doubling the present runs from 2.5 million adult fish to 5.0 million adult fish. This increase in production will be accomplished through comprehensive management of both wild and hatchery fish, but artificial propagation will play a major role in the augmentation process. The current husbandry techniques in existing hatcheries require improvements that may include changes in rearing densities, addition of oxygen, removal of excess nitrogen, and improvement in raceway design. Emphasis will be placed on the ability to increase the number of fish released from hatcheries that survive to return as adults. Rearing density is one of the most important elements in fish culture. Fish culturists have attempted to rear fish in hatchery ponds at densities that most efficiently use the rearing space available. Such efficiency studies require a knowledge of cost of rearing and the return of adults to the fisheries and to the hatchery

    Full Text Available Abstract Background Evidence suggests that folate deficiency may be causatively linked to depressive symptoms. However, little is known on the status of use of folic acid and vitamin supplements among people with mental disorders. This study examined the prevalence and the likelihood of use of folic acid or vitamin supplements among adults with depression and anxiety in comparison to those without these conditions. Methods Using data from 46, 119 participants (aged ≥ 18 years in the 2006 Behavioral Risk Factor Surveillance System survey, we estimated the adjusted prevalence and odds ratios with 95% confidence intervals for taking folic acid and vitamin supplements among those with ever diagnosed depression (n = 8, 019, ever diagnosed anxiety (n = 5, 546 or elevated depressive symptoms (n = 3, 978, defined as having a depression severity score of ≥ 10 on the Patient Health Questionnaire-8 diagnostic algorithm. Results Overall, women were more likely than men to take folic acid supplements 1-4 times/day (50.2% versus 38.7%, P Conclusion The prevalence and the likelihood of taking folic acid and vitamin supplements varied substantially by a history of diagnosed depression among both men and women and by a history of diagnosed anxiety among men, but not by presence of elevated depressive symptoms in either sex.

    The increasing consumption of nutritional supplements among the people mainly aiming at the replacement of nutrients and minerals in the organism has led the commercialization of a great number of brands of these products. Consequently the quality control of these products is of great interest to verify if their element contents agree the values presented in labels or in the instructions for their uses. In this study the elements Ca, Co, Cr, Cu, Fe, K, Na, Se and Zn were analyzed in multimineral supplements and vitamins samples using neutron activation analysis method. The results obtained compared with the values of the labels of nutritional supplements presented good agreement. For quality control of the analytical data, certified reference materials NIST 1400 Bone Ash and NIST 1633b Coal Fly Ash provided by National Institute of Standards and Technology were analysed. Accuracy and precision of the results were evaluated and Z score values obtained were lower than 2 indicating that the data found are within the certified values at 95% of significance level.

    Factors influencing nutritional supplement use by high school students were assessed. Comparisons were made between various groups of sports participants and non-sports participants. The Nutritional Supplement Use and Knowledge Scale was administered to 509 students. Mean supplement use score was 10.87 (SEM = 0.50, range 0-57). Mean knowledge score was 13.56 (SEM = 0.16, range 1-21). Significant relationships (p knowledge with use, and supplement use with gender. ANOVA found significant differences between supplement use by gender (p knowledge scores by sports category (p knowledge, supplement use, and subscores for protein, vitamins/minerals, knowledge, supplement use, and subscores for protein, vitamins/minerals, and carbohydrates were best discriminators of sport group membership. Greater knowledge about supplements was associated with less use; hence, education about supplements can be a deterrent to use. This study may help coaches, athletic trainers, athletic directors, teachers, physicians, and parents identify nutritional misconceptions held by adolescents.

    Growth faltering and anaemia remain unacceptably high among infants and young children in Ethiopia. In this study, we investigated the relationships among Fe supplement use (ISU), Hb concentration and linear growth, hypothesising positive relationships between ISU and Hb, ISU and linear growth and Hb and linear growth. We used a nationally representative data of 2400 children aged 6-24 months from the Ethiopian Demographic and Health Survey (EDHS) 2011, conducted following a stratified, two-stage cluster sampling. We examined the links by Pearson's correlation, bivariate and multivariate linear regression analyses and reported adjusted estimates. We found that ISU was not significantly associated with either Hb (β=1·09; 95 % CI -2·73, 5·01, P=0·567) or linear growth (β=0·07; 95 % CI -0·06, 0·21, P=0·217). We found a positive, however, weak, correlation between Hb and linear growth (r 0·09; 95 % CI 0·06, 0·11, PHb predicted linear growth independent of a variety dietary and non-dietary factors (β=0·08; 95 % CI 0·04, 0·11, PHb; age, birth type, size at birth, sex, breast-feeding duration, dietary diversity and deworming were independently associated with linear growth, indicating that Hb and linear growth are multifactorial with both nutritional and non-nutritional factors implicated. Further studies, with better design and exposure assessment, are warranted on the relation of ISU with Hb or linear growth.

    Full Text Available The use of food supplements containing botanicals is increasing in European markets. Although intended to maintain the health status, several cases of adverse effects to Plant Food Supplements (PFS have been described.To describe the self-reported adverse effects collected during the European PlantLIBRA PFS Consumer Survey 2011-2012, with a critical evaluation of the plausibility of the symptomatology reported using data from the literature and from the PlantLIBRA Poisons Centers' survey.From the total sample of 2359 consumers involved in the consumers' survey, 82 subjects reported adverse effects due to a total of 87 PFS.Cases were self-reported, therefore causality was not classified on the basis of clinical evidence, but by using the frequency/strength of adverse effects described in scientific papers: 52 out of 87 cases were defined as possible (59.8% and 4 as probable (4.6%. Considering the most frequently cited botanicals, eight cases were due to Valeriana officinalis (garden valerian; seven to Camellia sinensis (tea; six to Ginkgo biloba (Maidenhair tree and Paullinia cupana (guarana. Most adverse events related to the gastrointestinal tract, nervous and cardiovascular systems.Comparing the data from this study with those published in scientific papers and obtained by the PlantLIBRA Poisons Centers' survey, some important conclusions can be drawn: severe adverse effects to PFS are quite rare, although mild or moderate adverse symptoms can be present. Data reported in this paper can help health professionals (and in particular family doctors to become aware of possible new problems associated with the increasing use of food supplements containing botanicals.

    to increase understanding of psychosocial factors (behavioural, normative and control beliefs) motivating vitamin and mineral supplement use during pregnancy. ten focus group discussions and two in-depth interviews were conducted using a script comprising questions based on study objectives. All discussions were recorded, transcribed verbatim and analysed using a framework approach. South Australia, Australia. 40 women aged 21-45 years who were either pregnant oreducation level (secondary education only vs. post-secondary) and gravidity (first vs. subsequent pregnancy). all women, except one, used dietary supplements during pregnancy. Most women took supplements to achieve peace of mind knowing that nutrient requirements were 'definitely' being met. Other common factors motivating supplement use were the beliefs that supplementation: benefits maternal and fetal health; corrects known nutritional deficiencies; and is a more efficient method of obtaining required nutrients relative to food. Advice received from healthcare providers and marketing of supplements also motivated supplementation, while forgetting to take supplements was the most common barrier to use. Cost was only a barrier when considering whether or not to continue supplementation post-birth. women believe that supplements are an easier and more reliable source of nutrients than food intake alone, and rely on dietary supplementation as an insurance policy during pregnancy. Further studies are needed in larger and more representative samples to validate these findings and to test the effectiveness of information and intervention strategies targeting appropriate supplement use during pregnancy.

    Full Text Available 96 Normal 0 false false false CS JA X-NONE This article describes the results of a study of antioxidant activity of natural food supplements suggested for use in flour confectionery production. Oxidation rate of the model substance - cumene - was measured using a volumetric unit. Diagram of absorbed oxygen amount as a function of time (∆HO2 over t was built by measuring time in minutes and absorbed oxygen volume in cm3. This diagram was subsequently used to graphically determine the oxidation rate as the slope ratio of the line in specified coordinates. Afterwards, the oxidation rate was measured at a different initiation rate (different azobisisobutyronitrile solution volume, while all other parameters of the experiment remained unaltered. On the basis of the resulting data, diagrams of oxidation rate as a function of initiation rate were built for all investigated substances (both extracts and powders. The study revealed that apian products, including pollen and propolis, as well as kidney bean powder and phytosupplements (leaves of leather bergenia, lime blossom, heartsease, wild chamomile, pepper mint, bog rosemary, and elderflowers, possessed high antioxidant activity. According to the research data, the highest activity was detected in propolis  0.482·20 pollen 0.802 and powdered forms of pepper mint 1.066 leather bergenia leaves 0.937 heartsease 0.385 lime blossom 0.331 and kidney beans 0.323. Relatively lower antioxidant activity was found in powdered bog rosemary 0.242 elderflowers 0.238 and wild chamomile 0.212. (Introduction of the investigated supplements will allow inhibiting oxidation processes in the lipide fraction of foodstuffs, including flour confectionery, to ensure stability of their qualitative characteristics over a longer period.

    In 2001 the Idaho Fisheries Resource Office continued as a cooperator on the Salmon Supplementation Studies in Idaho Rivers (ISS) project on Pete King and Clear creeks. Data relating to supplementation treatment releases, juvenile sampling, juvenile PIT tagging, brood stock spawning and rearing, spawning ground surveys, and snorkel surveys were used to evaluate project data points and augment past data. Due to low adult spring Chinook returns to Kooskia National Fish Hatchery (KNFH) in brood year 1999 there was no smolt supplementation treatment release into Clear Creek in 2001. A 17,014 spring Chinook parr supplementation treatment (containing 1000 PIT tags) was released into Pete King Creek on July 24, 2001. On Clear Creek, there were 412 naturally produced spring Chinook parr PIT tagged and released. Using juvenile collection methods, Idaho Fisheries Resource Office staff PIT tagged and released 320 naturally produced spring Chinook pre-smolts on Clear Creek, and 16 natural pre-smolts on Pete King Creek, for minimum survival estimates to Lower Granite Dam. There were no PIT tag detections of brood year 1999 smolts from Clear or Pete King creeks. A total of 2261 adult spring Chinook were collected at KNFH. Forty-three females were used for supplementation brood stock, and 45 supplementation (ventral fin-clip), and 45 natural (unmarked) adults were released upstream of KNFH to spawn naturally. Spatial and temporal distribution of 37 adults released above the KNFH weir was determined through the use of radio telemetry. On Clear Creek, a total of 166 redds (8.2 redds/km) were observed and data was collected from 195 carcasses. Seventeen completed redds (2.1 redds/km) were found, and data was collected data from six carcasses on Pete King Creek.

    Fibromyalgia (FM) is a common disease that results in poor quality of life, causing widespread musculoskeletal pain and stiffness, fatigue, sleep disorders, and cognitive impairment among other symptoms. The lack of an effective treatment makes necessary a multidimensional management. FM patients usually seek, from different sources, information about possible benefits from foods, nutrients, or diets. Our objective was to investigate the dietary awareness, food allergies and/or intolerances (FAIs), and nutritional supplement (NS) consumption of FM patients. A questionnaire was prepared with six questions regarding dietary habits, FAIs, and NS use. The questionnaire was filled out by patients recruited in local fibromyalgia associations. One hundred and one women were suffering from FM, diagnosed for more than 6 months, mean age of 53.88 ± 7.78 years; 30% of them changed their diet because of their disease, trying to improve it, and most of them were also using some NS; 7% of women in this group had FAIs, a figure slightly higher than the FAI prevalence in the general population (2-5%) and positively associated with consumption of supplements. Among NS users, some differences were observed; past NS users currently consume a wider range of products, more than new NS users. Magnesium was one of the supplements most recommended specifically for FM. Seventy-four percentage of these patients used NS following advice from health professionals. Once patients are diagnosed, they change their dietary habits and nutritional supplement intake, seeking nutritional strategies to improve their symptoms. Health professionals' advice plays a relevant role.

    Full Text Available The aim of the study was to investigate the effect of antenatal iron-folic acid (IFA supplementation on child stunting in Nepalese children age <2 years. A retrospective cohort study design was used, in which a pooled cohort of 5235 most recent live births 2 years prior to interview from three Nepal Demographic and Health Surveys (2001, 2006 and 2011 was analysed. The primary outcome was stunting in children age <2 years. The main exposure variable was antenatal IFA supplementation. Multivariate Poisson regression analysis was performed. In our sample, 31% and 10% of Nepalese children age <2 years were stunted and severely stunted, respectively. The adjusted relative risk of being stunted was 14% lower in children whose mothers used IFA supplements compared to those whose mothers did not use (aRR = 0.86, 95% CI = 0.77–0.97. Additionally, the adjusted relative risk of being stunted was significantly reduced by 23% when antenatal IFA supplementation was started ≤6 months with ≥90 IFA supplements used during pregnancy (aRR = 0.77, 95% CI = 0.64–0.92. Antenatal IFA supplementation significantly reduced the risk of stunting in Nepalese children age <2 years. The greatest impact on the risk reduction of child stunting was when IFA supplements were started ≤6 months with ≥90 supplements were used.

    Full Text Available Abstract Background Low birth weight and maternal anemia remain intractable problems in many developing countries. The adequacy of the current strategy of providing iron-folic acid (IFA supplements only during pregnancy has been questioned given many women enter pregnancy with poor iron stores, the substantial micronutrient demand by maternal and fetal tissues, and programmatic issues related to timing and coverage of prenatal care. Weekly IFA supplementation for women of reproductive age (WRA improves iron status and reduces the burden of anemia in the short term, but few studies have evaluated subsequent pregnancy and birth outcomes. The Preconcept trial aims to determine whether pre-pregnancy weekly IFA or multiple micronutrient (MM supplementation will improve birth outcomes and maternal and infant iron status compared to the current practice of prenatal IFA supplementation only. This paper provides an overview of study design, methodology and sample characteristics from baseline survey data and key lessons learned. Methods/design We have recruited 5011 WRA in a double-blind stratified randomized controlled trial in rural Vietnam and randomly assigned them to receive weekly supplements containing either: 1 2800 μg folic acid 2 60 mg iron and 2800 μg folic acid or 3 MM. Women who become pregnant receive daily IFA, and are being followed through pregnancy, delivery, and up to three months post-partum. Study outcomes include birth outcomes and maternal and infant iron status. Data are being collected on household characteristics, maternal diet and mental health, anthropometry, infant feeding practices, morbidity and compliance. Discussion The study is timely and responds to the WHO Global Expert Consultation which identified the need to evaluate the long term benefits of weekly IFA and MM supplementation in WRA. Findings will generate new information to help guide policy and programs designed to reduce the burden of anemia in women and

    Full Text Available The objective of this study is to provide details on probiotic supplement use among young children in Taiwan.This study is based on the Taiwan Birth Cohort Study database. We used questionnaires to collect information on probiotic supplement use among young children from birth to 18 months of age, while also considering their demographic characteristics and other covariates. Low-birth-weight infants, preterm infants, those with birth defects, and those with caregivers who returned incomplete questionnaires were excluded. The final valid sample comprised 16,991 cases.Approximately half the children received probiotic supplements before the age of 18 months. Only 6.3% of the children received probiotic supplements during the two periods of birth to 6 months and 7 to 18 months. Firstborn children, native mothers, mothers with higher educational levels, higher family income, and parents who lead healthy lifestyles were positively related to probiotic supplement use among children. Young children who were breastfed, with eczema, or with gastrointestinal tract problems were significantly positively associated with probiotic supplement use.The findings show that probiotic supplement usage among young children is associated with a more socially advantaged circumstance and certain child health factors, such as eczema, diarrhea, and constipation. Parents might use probiotic supplements for prevention or treatment of child diseases. The findings of this research could serve as a baseline for future studies, and provide insight into probiotic supplement use behavior for health professionals caring for infants and young children.

    The use of nutritional supplements (NS) places athletes at great risk for inadvertent doping. Due to the paucity of data on supplement use, this study aimed to determine the proportion of Ugandan athletes using nutritional supplements and to investigate the athletes' motivation to use these supplements. A cross-sectional study was conducted in which an interviewer-administered questionnaire was used to collect data from 359 professional athletes participating in individual (boxing, cycling, athletics) and team (basketball, rugby, football, netball, and volleyball) sports. The data were categorized, and a Chi-square test was used for statistical analysis. Of the 359 athletes, 48 (13.4%) used nutritional supplements. Carbohydrate supplements, energy drinks, vitamin and mineral supplements, fish oils, and protein supplements were the most common supplements used by athletes. NS use was significantly more common among athletes who played rugby and basketball ( X 2 = 61.101, p sport for 5-10 years ( X 2 = 7.460, p = 0.024), and athletes who had attained a tertiary education ( X 2 = 33.377, p performance and health. Compared to NS use by athletes elsewhere, NS use among Ugandan athletes was low. However, determinants of athlete NS use in the current study (category of sport and duration of time spent playing the sport) are similar to those reported elsewhere.

    Full Text Available A consumer survey on dietary supplement consumption was carried out on 494 consumers aged 20 years and older in Chiang Mai province. The percentage of consumers who regularly consumed dietary supplements was 38.5%. Vitamins and minerals were the most consumed products, followed by functional drinks, functional foods, protein extracts, dietary fibre, cod liver oil, phytochemicals, algae products, fat absorbers, fish oils and bee products in that order. Females and participants who had recommended waistlines, had higher income, usually felt stressed or sick, and who preferred eating fruits/vegetables or routinely drank water tended to have a higher rate of consumption of dietary supplements. Participants gave priority over a product with guaranteed quality when they made decision to purchase dietary supplements, but their purchase was also influenced by the attractiveness of the product and advertisement for it.

  3. Studying dark energy with galaxy cluster surveys

    Galaxy cluster surveys provide a powerful means of studying the density and nature of the dark energy. The redshift distribution of detected clusters in a deep, large solid angle SZE or X-ray survey is highly sensitive to the dark energy equation of state. Accurate constraints at the 5% level on the dark energy equation of state require that systematic biases in the mass estimators must be controlled at better than the ∼10% level. Observed regularity in the cluster population and the availability of multiple, independent mass estimators suggests these precise measurements are possible. Using hydrodynamical simulations that include preheating, we show that the level of preheating required to explain local galaxy cluster structure has a dramatic effect on X-ray cluster surveys, but only a mild effect on SZE surveys. This suggests that SZE surveys may be optimal for cosmology while X-ray surveys are well suited for studies of the thermal history of the intracluster medium

    In 2002 the Idaho Fisheries Resource Office continued working as a cooperator on the Salmon Supplementation Studies in Idaho Rivers (ISS) project on Pete King and Clear creeks. Data relating to supplementation treatment releases, juvenile sampling, juvenile PIT tagging, broodstock spawning and rearing, spawning ground surveys, and snorkel surveys were used to evaluate the project data points and augment past data. Supplementation treatments included the release of 51,329 left ventral-clipped smolts into Clear Creek (750 were PIT tagged), and 12,000 unmarked coded-wire tagged parr into Pete King Creek (998 were PIT tagged). Using juvenile collection methods, Idaho Fisheries Resource Office staff PIT tagged and released 579 naturally produced spring chinook juveniles in Clear Creek, and 54 on Pete King Creek, for minimum survival estimates to Lower Granite Dam. For Clear Creek, minimum survival estimates to Lower Granite Dam of hatchery produced supplementation and naturally produced PIT tagged smolts, were 36.0%, and 53.1%, respectively. For Pete King Creek, minimum survival estimates to Lower Granite Dam, of hatchery produced supplementation smolts and naturally produced smolts PIT tagged as parr and presmolts, were 18.8%, and 8.3%, respectively. Adults collected for broodstock in 2002 represented the final adult broodstock group collected for the ISS project. Twenty-six ventral clipped, and 28 natural adult spring chinook were transported above the weir. Monitoring and evaluation of spawning success was continued on Clear and Pete King creeks. A total of 69 redds were counted and 79 carcasses were recovered on Clear Creek. Two redds were observed and no carcasses were collected on Pete King Creek.

    Background The popularity of botanical products is on the rise in Europe, with consumers using them to complement their diets or to maintain health, and products are taken in many different forms (e.g. teas, juices, herbal medicinal products, plant food supplements (PFS)). However there is a scarcity of data on the usage of such products at European level. Objective To provide an overview of the characteristics and usage patterns of PFS consumers in six European countries. Design Data on PFS usage were collected in a cross-sectional, retrospective survey of PFS consumers using a bespoke frequency of PFS usage questionnaire. Subjects/setting A total sample of 2359 adult PFS consumers from Finland, Germany, Italy, Romania, Spain and the United Kingdom. Data analyses Descriptive analyses were conducted, with all data stratified by gender, age, and country. Absolute frequencies, percentages and 95% confidence intervals are reported. Results Overall, an estimated 18.8% of screened survey respondents used at least one PFS. Characteristics of PFS consumers included being older, well-educated, never having smoked and self-reporting health status as “good or very good”. Across countries, 491 different botanicals were identified in the PFS products used, with Ginkgo biloba (Ginkgo), Oenothera biennis (Evening primrose) and Cynara scolymus (Artichoke) being most frequently reported; the most popular dose forms were capsules and pills/tablets. Most consumers used one product and half of all users took single-botanical products. Some results varied across countries. Conclusions The PlantLIBRA consumer survey is unique in reporting on usage patterns of PFS consumers in six European countries. The survey highlights the complexity of measuring the intake of such products, particularly at pan-European level. Incorporating measures of the intake of botanicals in national dietary surveys would provide much-needed data for comprehensive risk and benefit assessments at the European

    Iron and folate supplementation can effectively control and prevent anaemia in pregnancy. In Ethiopia, all pregnant women are prescribed iron folate during their ANC visit. However, limited adherence is thought to be a major reason for the low effectiveness of iron supplementation programs. Therefore this study was done to investigate factors associated with compliance of prenatal iron folate supplementation among women who gave birth in the last 12 months before the survey in Mecha district. Community based cross sectional study design was employed in Mecha district from June 25 - July 15/2013. A sample of 634 women who gave birth 12 months before the survey was included in the study. Study participants were selected by systematic random sampling technique after allocating the total sample to each kebele proportionally. Data were collected using a pre-tested structured Amharic questionnaire. Collected data were edited, coded and entered to Epi info version 3.1 and exported to' SPSS version 16. Bivariate and multivariable analysis was computed. A total of 628 women who gave birth twelve months before the survey were enrolled. In this study only 20.4% of participants were compliant with iron foliate supplementation. In multivariable analysis, age of the mother, educational status of the mother, knowledge of anaemia and iron folate tablets, and history of anaemia during pregnancy were significantly associated with compliance to iron folate supplementation (Ptablets would harm the baby and fear of side effects were the major reasons given for noncompliance. Compliance to iron folate supplementation is very low in the study area. Increasing female education and increasing knowledge of women about anaemia and iron folate tablets are recommended to increase compliance to iron folate supplementation.

    Large introductory astronomy and physics survey courses can be very challenging and stressful. The University of Wisconsin-Madison Physics Learning Center (PLC) reaches about 10 percent of the students in four introductory physics courses, algebra and calculus based versions of both classical mechanics and electromagnetism. Participants include those potentially most vulnerable to experiencing isolation and hence to having difficulty finding study partners as well as students struggling with the course. They receive specially written tutorials, conceptual summaries, and practice problems; exam reviews; and most importantly, membership in small groups of 3 - 8 students which meet twice per week in a hybrid of traditional teaching and tutoring. Almost all students who regularly participate in the PLC earn at least a "C,” with many earning higher grades. The PLC works closely with other campus programs which seek to increase the participation and enhance the success of underrepresented minorities, first generation college students, and students from lower-income circumstances; and it is well received by students, departmental faculty, and University administration. The PLC staff includes physics education specialists and research scientists with a passion for education. However, the bulk of the teaching is conducted by undergraduates who are majoring in physics, astronomy, mathematics, engineering, and secondary science teaching (many have multiple majors). The staff train these enthusiastic students, denoted Peer Mentor Tutors (PMTs) in general pedagogy and mentoring strategies, as well as the specifics of teaching the physics covered in the course. The PMTs are among the best undergraduates at the university. While currently there is no UW-Madison learning center for astronomy courses, establishing one is a possible future direction. The introductory astronomy courses cater to non-science majors and consequently are less quantitative. However, the basic structure

    This study aimed to evaluate changes in total body water (TBW) in soccer athletes using a deuterium oxide dilution method and bioelectrical impedance (BIA) formulas after 7 days of creatine supplementation. In a double-blind controlled manner, 13 healthy (under-20) soccer players were divided randomly in 2 supplementation groups: Placebo (Pla, n=6) and creatine supplementation (CR, n=7). Before and after the supplementation period (0.3 g/kg/d during 7 days), TBW was determined by deuterium oxide dilution and BIA methods. 7 days of creatine supplementation lead to a large increase in TBW (2.3±1.0 L) determined by deuterium oxide dilution, and a small but significant increase in total body weight (1.0±0.4 kg) in Cr group compared to Pla. The Pla group did not experience any significant changes in TBW or body weight. Although 5 of 6 BIA equations were sensitive to determine TBW changes induced by creatine supplementation, the Kushner et al. 16 method presented the best concordance levels when compared to deuterium dilution method. In conclusion, 7-days of creatine supplementation increased TBW determined by deuterium oxide dilution or BIA formulas. BIA can be useful to determine TBW changes promoted by creatine supplementation in soccer athletes, with special concern for formula choice. © Georg Thieme Verlag KG Stuttgart · New York.

    One in five maternal deaths are directly attributable to anaemia in the world. The World Health Organization recommends iron supplementation from the second trimester of pregnancy to 45 days after delivery. The aim of this study was to determine the compliance rate of iron-folate consumption and the factors associated with iron-folate consumption among post-natal mothers in Nepal. This study utilised the data of Nepal Demographic and Health Survey (NDHS) 2011. The NDHS 2011 is a cross sectional and nationally representative survey. Of the 4,148 respondents, only 20.7% consumed iron throughout the post-natal period for 45 days. Mothers who had higher and secondary education [adjusted Odd ratio (aOR) 3.101; 95% CI (2.268-4.240)]; had attended four or more antenatal care visits [aOR 9.406; 95% CI (5.552-15.938)]; lived in Far-western development region [aOR 1.822; 95% CI (1.387-2.395)]; delivered in health facility [aOR 1.335; 95% CI (1.057-1.687)]; and attended postnatal care [aOR 2.348; 95% CI (1.859-2.965)] were more likely to take iron for 45 days of postpartum. Intervention to increase the compliance with the postpartum iron-folate supplementation are required to avoid adverse pregnancy outcomes associated with poor iron status with especial focus on the mothers who delivered at homes and did not attend post-natal check up.

    Protein-based sports supplements are among the more common types of nutrition supplements consumed by athletes; however, there is currently limited data investigating the knowledge, motivations and occurrence of use among the adolescent population (13-18 years). This pilot study looks to obtain initial data regarding the use of protein supplements in this population. This study investigates the understanding and occurrence of protein supplement use in 87 adolescent athletes based in an Australian capital city who compete in a variety of sports. Sources of information, regularity of use, purchasing habits, associated risk knowledge and supplement beliefs were examined using a self-reported, written questionnaire. A total of 60% (n = 52) of athletes reported using protein supplements, with a positive relationship between age and use (P supplement consumption, with the most common risk reported as 'I don't know' (22%). Coaches were found to initiate protein supplement use more than other figures in the athlete's life (50%) and were the primary source of information regarding supplements (58%). It was found that 19% of adolescent athletes obtained information about protein supplements from the Internet, and 17% of all consumers purchase their supplements online. The evident lack of knowledge regarding protein supplements demonstrates a necessity for further education of athletes, coaches and families regarding the responsible purchasing and use of protein supplements in the current landscape of sports nutrition. Future research should further explore the role of the Internet in protein supplement purchase and education. © 2017 Dietitians Association of Australia.

    Purpose. Antioxidant supplements may reduce age-related macular degeneration (AMD) progression. The macular carotenoids are of particular interest because of their biochemical, optical, and anatomic properties. This classic twin study was designed to determine the heritability of macular pigment (MP) augmentation in response to supplemental lutein (L) and zeaxanthin (Z). Methods. A total of 322 healthy female twin volunteers, aged 16–50 years (mean 40 ± 8.7) was enrolled in a prospective, nonrandomized supplement study. Macular pigment optical density (MPOD) measurements using two techniques (2-wavelength fundus autofluorescence [AF] and heterochromatic flicker photometry [HFP]), and serum concentrations of L and Z, were recorded at baseline, and at 3 and 6 months following daily supplementation with 18 mg L and 2.4 mg Z for a study period of 6 months. Results. At baseline, mean MPOD was 0.44 density units (SD 0.21, range 0.04–1.25) using HFP, and 0.41 density units (SD 0.15) using AF. Serum L and Z levels were raised significantly from baseline following 3 months' supplementation (mean increase 223% and 633%, respectively, P < 0.0001 for both), with no MPOD increase. After 6 months' supplementation, a small increase in MPOD was seen (mean increase 0.025 ± 0.16, P = 0.02, using HFP). Subdivision of baseline MPOD into quartiles revealed that baseline levels made no difference to the treatment effect. Genetic factors explained 27% (95% confidence interval [CI] 7–45) of the variation in MPOD response. Distribution profiles of macular pigment did not change in response to supplementation. Conclusions. MPOD response to supplemental L and Z for a period of 6 months was small (an increase over baseline of 5.7% and 3.7%, measured using HFP and AF, respectively), and was moderately heritable. Further study is indicated to investigate the functional and clinical impact of supplementation with the macular carotenoids. PMID:22700713

    The potential acute genoprotective effect of orange juice supplementation was investigated. Six healthy subjects (aged 33 to 60 years; 3 women and 3 men) were asked to drink 400 mL of commercial orange juice, which contained 100 mg vitamin C and 40.8 g sugar. Venous blood (2 mL) was taken before and 2 h after ingestion (test trial). A week later, the subjects were asked to repeat the trial by drinking 400 mL water with 100 mg vitamin C and 40.8 g glucose (control trial). Lymphocytes isolated from blood samples underwent comet assay on the day of collection. Pre- and postingestion DNA damage scores were measured in both the test and control trials. Results showed that there was a significant decrease in DNA damage induced by hydrogen peroxide after 2 h of supplementation with orange juice, and no change in baseline DNA damage. There was no significant decrease in the DNA damage in lymphocytes in the control trial.

    Most of the elderly have vitamin D deficiency, which is defined as a serum level below 30 ng/mL. To identify the characteristics of patients over 65 receiving vitamin D supplements by their primary care physician. A descriptive and transverse study was performed on patients over 65 years old admitted to Care Following at the La Croix Rouge in Nantes from September 2012 to February 2013. The criteria for vitamin D supplementation, the type (vitamin D2 or D3, continuous prescription or not, route of administration) and starting date of vitamin D supplementation were identified. Serum 25-hydroxyvitamin D (25OHD) was measured at admission. Of 163 patients included, 44% received vitamin D supplements (n=71). The patient aged over 80 benefited more often from vitamin D supplementation (p=0.019), so did women (p=0.034), patients with fractures (p=0.05), patients with osteoporosis treatments (pvitamin D supplementation less often than the others (p=0.046). The dosage of the vitamin D was normal for 28% of patients (n=46). The prescription of vitamin D supplements to the elderly is still too scarce and should be encouraged, especially in non-bone indications.

    Despite growing evidence that bipolar disorder often emerges in adolescence, there are limited data regarding treatment patterns of youth with bipolar disorder in community samples. Our objective was to present the prevalence and clinical correlates of treatment utilization for a nationally representative sample of US adolescents with bipolar disorder. Analyses are based on data from the National Comorbidity Survey-Adolescent Supplement, a face-to-face survey of 10,123 adolescents (ages 13-18) identified in household and school settings. We found that of adolescents meeting DSM-IV criteria for bipolar I or II disorder (N = 250), 49 % were treated for depression or mania, 13 % were treated for conditions other than depression or mania, and 38 % did not report receiving treatment. Treatment for depression or mania was associated with increased rates of suicide attempts, as well as greater role disability and more comorbid alcohol use relative to those who had not received treatment. Treated adolescents had triple the rate of ADHD and double the rates of behavior disorders than those without treatment. Our findings demonstrate that a substantial proportion of youth with bipolar disorder do not receive treatment, and of those who do, many receive treatment for comorbid conditions rather than for their mood-related symptoms. Treatment was more common among youth with severe manifestations and consequences of bipolar disorder and those with behavior problems. These trends highlight the need to identify barriers to treatment for adolescents with bipolar disorder and demonstrate that those in treatment are not representative of youth with bipolar disorder in the general population.

    To look for possible developmental effects in the offspring of jojoba meal-treated Wistar rats, and to distinguish between the effects of reduced food intake and the specific developmental effects of jojoba meal itself, mated female rats were divided into three groups of 20 rats. They received during gestation: (a) normal rodent food (control group); (b) normal rodent food supplemented with 3% defatted jojoba meal (jojoba group); or (c) normal rodent food pair-fed with the jojoba group (pair-fed group). The jojoba meal group showed approximately 30% inhibition of food intake. Ten rats from each group were killed on gestation day 21. Compared to the control group, foetal body weight was reduced in both the jojoba and pair-fed groups, with a greater reduction in the jojoba group. Skeletal ossification was retarded to the same extent in both the jojoba and pair-fed groups. The other 10 rats from each group were left to produce litters. Compared with controls, the body weight of the pups was lower in both the jojoba and pair-fed groups; the reduction was slightly greater in the jojoba group, but this difference disappeared after 1 week. The offspring showed no other abnormalities and reproduced normally. We conclude that, at the dose used, the retardation in foetal skeletal ossification, induced by jojoba meal supplementation during gestation, is due to food intake inhibition. Moreover, the lower birth weight of the young of jojoba-treated dams compared with the pair-fed group is merely due to a lower body weight gain during gestation.

    Idaho Supplementation Studies (ISS) will help determine the utility of supplementation as a potential recovery tool for decimated stocks of spring and summer chinook salmon, Oncorhynchus tshawytscha, in Idaho as part of a program to protect, mitigate, and enhance fish and wildlife affected by the development and operation of hydroelectric power plants on the Columbia River. The objectives are to: (1) monitor and evaluate the effects of supplementation on presmolt and smolt numbers and spawning escapements of naturally produced salmon; (2) monitor and evaluate changes in natural productivity and genetic composition of target and adjacent populations following supplementation; and (3) determine which supplementation strategies provide the quickest and highest response in natural production without adverse effects on productivity. Field work began in 1991 with the collection of baseline data from treatment and some control streams. Full implementation began in 1992 with baseline data collection on treatment and control streams and releases of supplementation fish into several treatment streams. Field methods included snorkeling to estimate chinook salmon parr populations, PIT tagging summer parr to estimate parr-to-smolt survival, multiple redd counts to estimate spawning escapement and collect carcass information. Screw traps were used to trap and PIT tag outmigrating chinook salmon during the spring and fall outmigration. Weirs were used to trap and enumerate returning adult salmon in select drainages

    A mail survey was conducted on 13,000 males in the JNIH-ABCC Life Span Study population aged 40 to 69 in January 1965. The information sought was largely related to what are considered to be risk factors in the development of cerebral and cardiovascular diseases. The questionnaire included such items as residential history, occupation, physical activity, smoking, dietary custom, educational history, medical history, and family history. The final response rate was high (93%) after three mailings and supplemental field visits. As a preliminary analysis, the distribution of these variables was compared by city and exposure status. This analysis revealed that Hiroshima subjects were more educated, were more often managers, clerical workers, and sales workers, performed less physical activity, had more living space and ate a more Western type diet than Nagasaki subjects. It was also shown that the distribution of such variables as place of birth, present address, occupation, marital status, and education differed by the exposure status of subjects. Some methodological problems inherent in a mail survey such as completeness and reliability of obtained information were discussed. 15 references, 1 figure, 28 tables.

    Recent evidence obtained from a rodent model of birth asphyxia shows that supplementation of the maternal diet with creatine during pregnancy protects the neonate from multi-organ damage. However, the effect of increasing creatine intake on creatine homeostasis and biosynthesis in females, particularly during pregnancy, is unknown. This study assessed the impact of creatine supplementation on creatine homeostasis, body composition, capacity for de novo creatine synthesis and renal excretory function in non-pregnant and pregnant spiny mice. Mid-gestation pregnant and virgin spiny mice were fed normal chow or chow supplemented with 5 % w/w creatine for 18 days. Weight gain, urinary creatine and electrolyte excretion were assessed during supplementation. At post mortem, body composition was assessed by Dual-energy X-ray absorptiometry, or tissues were collected to assess creatine content and mRNA expression of the creatine synthesising enzymes arginine:glycine amidinotransferase (AGAT) and guanidinoacetate methyltransferase (GAMT) and the creatine transporter (CrT1). Protein expression of AGAT and GAMT was also assessed by Western blot. Key findings of this study include no changes in body weight or composition with creatine supplementation; increased urinary creatine excretion in supplemented spiny mice, with increased sodium (P < 0.001) and chloride (P < 0.05) excretion in pregnant dams after 3 days of supplementation; lowered renal AGAT mRNA (P < 0.001) and protein (P < 0.001) expressions, and lowered CrT1 mRNA expression in the kidney (P < 0.01) and brain (P < 0.001). Creatine supplementation had minimal impact on creatine homeostasis in either non-pregnant or pregnant spiny mice. Increasing maternal dietary creatine consumption could be a useful treatment for birth asphyxia.

    A survey was designed to examine the use of dietary supplements by Brazilian physical education professionals. The study included 131 Brazilian physical education professionals (83 men and 48 women). A descriptive statistical analysis was performed (mean, standard deviation, and absolute and relative frequencies). A chi-square test was applied to evaluate differences in use of dietary supplements according to particular variables of interest (p supplements. Approximately 59% of dietary supplement users took two or more kinds of supplements. Among users of supplements, men professionals (73%) consumed more dietary supplements than women (27%). The most-consumed dietary supplement was whey protein (80%). The results showed a higher use of dietary supplements by men. The most-consumed supplements were rich in protein. The consumption of dietary supplements by almost half of the participants in this study suggests that participants did not consider their dietary needs to be met by normal diet alone.

    To examine the association of the Supplemental Nutrition Assistance Program (SNAP) and diet quality among low-income adults. We examined US nationally representative data from the National Health and Nutrition Examination Surveys 2003-2004, 2005-2006, 2007-2008, and 2009-2010. The data were analyzed from October 7, 2013, to March 1, 2014. The analytic sample consisted of 4211 low-income adults aged 20 to 64 years, of whom 1830 participate in SNAP. We adhered to the National Cancer Institute method in calculating the Healthy Eating Index 2010 and other dietary indicators, such as empty calorie intake. Bivariate and multivariable regression was used to compare SNAP participants and income-eligible nonparticipants among the full sample and subsamples of age, sex, race/ethnicity, and food insecurity. Compared with low-income nonparticipants, adjusted analyses reveal that SNAP participants had lower dietary quality scores overall (42.58 vs 44.36, P≤.0001) and lower scores for fruits and vegetables, seafood and plant proteins (1.55 vs 1.77, P≤.0022), and empty calories (9.03 vs 9.90, P≤.0001), but they exhibited comparable scores on whole grain, refined grain, total dairy, total protein, fatty acid, and sodium intakes. The association between SNAP participation and lower dietary quality was statistically significant among women, Hispanics, young adults, and individuals who were food secure. Our analyses suggest that SNAP participants have lower dietary quality than their income-eligible nonparticipant counterparts. Although SNAP has an important role in providing nutrition assistance to eligible low-income individuals, interventions are warranted to improve the dietary quality of participants.

    Full Text Available Nutritional status in patients on hemodialysis is always of concern as malnutrition predisposes to excess morbidity and mortality. Most of the nutritional supplements available in the market are expensive. We explored the possibility of improving nutrition of the patients on maintenance hemodialysis by supplementation of calories and proteins that can be given in the form of a palatable and economical gruel in this prospectively designed, open labeled study. Patients who were on maintenance hemodialysis (twice a week for a period of at least 6 months were divided into two groups. The study group was given the gruel supplement and the control group was not given the gruel supplement. Nutritional status was assessed in the study group and controls at 0 and 3 months by the following parameters: percentage body fat, mid arm muscle circumference and serum albumin. Analysis of results revealed that there was a significant decline in the protein intake at the end of the 3 rd month in the control group (P = 0.01. Other parameters did not show significant change at the end of the study period in both groups. The nutritional supplement can be assumed to have helped at least in the maintenance of protein intake over this short period and could possibly in the long run contribute to improvement of nutritional parameters.

    Full Text Available Introduction. Since their first appearance and through present day, dietary supplements remain popular among customers. In medical practice, dietary supplements are used as an additional source of nutrients and biologically active compounds aimed at optimization of various types of metabolism as well as normalization and/or improvement of functional state of organs and systems.Objective: is to evaluate effectiveness and safety of a dietary supplement “De Alex” in patients with benign prostatic hyperplasia (BPH.Materials and methods. The study included 35 volunteers who signed the informed consent form and received treatment at urology departments of the S.I. Spasokukotsky Municipal Clinical Hospital. The main group included 20 men, the control group included 15 men. “De Alex” dietary supplement was administered according to the following scheme: 1 tablet 3 times a day for the first 3 months, then 4 tablets a day for 2 more months. Clinical, laboratory and instrumental data were evaluated as well as validated questionnaires filled out by the patients.Results. There weren’t any allergic reactions or individual intolerance to the “De Alex”  dietary supplement in the main group. The total IPSS score decreased in all patients, and symptoms of the lower urinary tract were less pronounced. “De Alex” administration didn’t affect the levels of prostate-specific antigen and testosterone. In the studied subgroups, a moderate decrease of the prostate volume was observed. Conclusions. The “De Alex” dietary supplement has a satisfactory safety profile. In patients with BPH the supplement causes a moderate decrease of the prostate volume.

    Iron deficiency is the most common nutritional disorder in the world, and it is the only common nutrient deficiency in industrialised nations. It is thought to be the most common cause of anaemia. Use of iron supplementation in Switzerland has not been previously quantified in detail. We quantified use of iron supplementation from Swiss data and compared it with data from the UK. We assessed the frequency of serum ferritin and haemoglobin tests prior to newly started iron therapy to see whether use was based on documented low iron levels or blood parameters, especially in the case of parenteral iron supplementation. We conducted a retrospective descriptive study of prescription iron supplementation use, and compared use of oral or parenteral iron drugs between Switzerland (CH) and the UK. We retrieved Swiss data from the Swiss Health Insurance Helsana Group, and UK data were from the Clinical Practice Research Datalink (CPRD). The study period was 2012 to 2014. The 3-year prevalence of iron supplementation was 9.4% in Switzerland and 4.4% in the UK. Iron use increased slightly between 2012 and 2014 in both countries (CH +0.3%, UK +0.2%). Recorded parenteral iron administration was roughly a thousand times higher in Switzerland (1.9%) than in the UK in 2014. In Switzerland, iron supplements were mostly given to patients aged 20 to 49 years or older than of 80 years. In the UK, iron supplementation was less frequent in younger people, but more prevalent in the elderly. Prior to a first iron prescription, ferritin tests were done more frequently in Switzerland (oral 67.2%, parenteral 86.6%) than in the UK (oral 43.3%, parenteral 65.5%). Haemoglobin was measured before a new parenteral iron therapy rarely in Switzerland (oral 14.9%, parenteral 11.7%), but frequently in the UK (oral 77.4%, parenteral 85.6%). Iron supplementation is more common in Switzerland than in the UK, particularly parenteral iron supplementation. Haemoglobin measurements prior to a new parenteral

    The increasing illegal and on-line market of medicines and food supplements is helping the widespread diffusion of harmful counterfeit and forbidden products among consumers of developed countries. The objectives of this survey were the description of the main frauds recognized by public officers and the detection of illegal or counterfeit drugs and food supplements. Medicines and food supplements found by Police forces on the illegal market or resulting from seizures made by Italian Customs authorities were visually inspected and analysed to evaluate their quality and the presence of other undeclared substances. The visual inspection and the chemical analysis revealed unsuitable packaging (mostly lacking of adequate information for consumers), absence of the declared active substances and presence of undeclared active substances. Products containing doping agents, illegal substances and active ingredients requiring medical supervision were found. The present work confirmed the health risk associated with assumption of medicines purchased on the Internet and from the illegal supply chain and evidenced a new threat to consumer safety related to the presence of pharmaceutical active ingredients in food supplements claiming to contain only "natural ingredients".

    Distal fingertip amputations are common injuries in work- and non-work-related accidents. There is a paucity of evidence to support use of any one treatment. We conducted a study to better understand how surgeon and patient factors influence the treatment preferences for distal fingertip amputations among a cross section of US and international hand surgeons. We sent a 16-question survey to the American Association for Hand Surgery and reciprocal international hand societies and analyzed the response data using a logistic regression model. We hypothesized that hand surgeons' treatment preferences would be varied and influenced by surgeon and patient demographics. One hundred ninety-eight hand surgeons (62% US, 38% international) responded to the survey. For each clinical scenario (Allen levels 2, 3, and 4 and volar oblique amputations), there were wide variations in treatment preferences. Wound care was less likely performed by surgeons with more than 30 years of experience or plastic surgery backgrounds. Replantation was less likely performed by US surgeons and private practice surgeons. Pedicle and homodigital flaps were more commonly performed internationally. Surgeons in practice for less than 5 years were more likely to perform skeletal shortening. For all levels and orientations of fingertip amputation queried, there is a wide range of treatment preferences. Our survey results highlight the need for a prospective randomized trial to elucidate the most effective treatments for fingertip amputations.

    2015-01-01

    The purpose of this study is to use a molecular docking approach to identify potential estrogen mimics or anti-estrogens in phytochemicals found in popular dietary herbal supplements. In this study, 568 phytochemicals found in 17 of the most popular herbal supplements sold in the United States were built and docked with two isoforms of the estrogen receptor, ERα and ERβ (a total of 27 different protein crystal structures). The docking results revealed six strongly docking compounds in Echinacea, three from milk thistle (Silybum marianum), three from Gingko biloba, one from Sambucus nigra, none from maca (Lepidium meyenii), five from chaste tree (Vitex agnus-castus), two from fenugreek (Trigonella foenum-graecum), and two from Rhodiola rosea. Notably, of the most popular herbal supplements for women, there were numerous compounds that docked strongly with the estrogen receptor: Licorice (Glycyrrhiza glabra) had a total of 26 compounds strongly docking to the estrogen receptor, 15 with wild yam (Dioscorea villosa), 11 from black cohosh (Actaea racemosa), eight from muira puama (Ptychopetalum olacoides or P. uncinatum), eight from red clover (Trifolium pratense), three from damiana (Turnera aphrodisiaca or T. diffusa), and three from dong quai (Angelica sinensis). Of possible concern were the compounds from men's herbal supplements that exhibited strong docking to the estrogen receptor: Gingko biloba had three compounds, gotu kola (Centella asiatica) had two, muira puama (Ptychopetalum olacoides or P. uncinatum) had eight, and Tribulus terrestris had six compounds. This molecular docking study has revealed that almost all popular herbal supplements contain phytochemical components that may bind to the human estrogen receptor and exhibit selective estrogen receptor modulation. As such, these herbal supplements may cause unwanted side effects related to estrogenic activity.

    Despite substantial evidence on the prevalence and correlates of overweight and obesity (OW/OB) in adults with bipolar disorder (BD), little is known about this topic in adolescents with BD. The method consisted of the National Comorbidity Survey-Adolescent Supplement, a face-to-face survey of mental disorders from 2001 through 2004, using a modified version of the fully structured World Health Organization Composite International Diagnostic Interview. Participants were adolescents 13 to 17 years of age, with bipolar disorder I or II (n = 295), major depressive disorder (n = 1,112), or controls with neither mood disorder (n = 8,716). Analyses examined for group differences in the prevalence of OW/OB and for correlates of OW/OB in the group with BD. There were no significant differences in weight categories across groups. OW and OB in adolescents with BD were associated with significantly higher lifetime rates of suicide attempt (odds ratio 3.02, 95% CI 1.11-8.24), physical or sexual abuse (2.82, 1.20-6.60), binge eating or bulimia (2.66, 1.13-6.26), and conduct disorder (2.60, 1.10-6.13) in covariate-adjusted analyses. OW and OB also were significantly associated with seeing a professional for depression, being hospitalized overnight for depression, and receiving general medical treatment. The similar prevalence of OW/OB in adolescents with and without BD suggests that this potent association in adults likely comprises a consequence of BD or its correlates. In contrast, the strong association of OW/OB with proxies for depression severity, including suicide attempts and hospitalization, is already evident even in this young, nonclinical sample. Studies are warranted to determine whether early intervention of OW/OB in BD might optimize physical and mental health. Copyright © 2016 American Academy of Child and Adolescent Psychiatry.

    Consumers nowadays are playing an active role in their health-care. A special case is the increasing number of women, who are reluctant to use exogenous hormone therapy for the treatment of menopausal symptoms and are looking for complementary therapies. However, food supplements are not clearly regulated in Europe. The EFSA has only recently begun to address the issues of botanical safety and purity regulation, leading to a variability of content, standardization, dosage, and purity of available products. In this study, isoflavones (puerarin, daidzin, genistin, daidzein, glycitein, genistein, formononetin, prunetin, and biochanin A) from food supplements (n = 15) for menopausal symptoms relief are evaluated and compared with the labelled information. Only four supplements complied with the recommendations made by the EC on the tolerable thresholds. The intestinal bioavailability of these compounds was investigated using Caco-2 cells. The apparent permeability coefficients of the selected isoflavonoids across the Caco-2 cells were affected by the isoflavone concentration and product matrix.

    Parkinson's disease (PD) is an oxidative stress-mediated degenerative disorder. Elevated plasma homocysteine (Hcy) is frequently found in the levodopa-treated PD patients, is associated with disease progression and is a marker of oxidative stress. Whey protein is a rich source of cysteine, and branched-chain amino acids (BCAA). It has been shown that supplementation with Whey protein increases glutathione synthesis and muscle strength. In this study, we conducted a placebo-controlled, double-blind study (NCT01662414) to investigate the effects of undenatured Whey protein isolate supplementation for 6months on plasma glutathione, plasma amino acids, and plasma Hcy in PD patients. Clinical outcome assessments included the unified Parkinson's disease rating scale (UPDRS) and striatal L-3,4-dihydroxy-6-(18)F-fluorophenylalanine (FDOPA) uptake were determined before and after supplementation. 15 patients received Whey protein, and 17 received Soy protein, served as a control group. Significant increases in plasma concentration of reduced glutathione and the ratio of reduced to oxidized glutathione were found in the Whey-supplemented patients but not in a control group. This was associated with a significant decrease of plasma levels of Hcy. The plasma levels of total glutathione were not significantly changed in either group. Plasma BCAA and essential amino acids (EAA) were significantly increased in the Whey-supplemented group only. The UPDRS and striatal FDOPA uptake in PD patients were not significantly ameliorated in either group. However, significant negative correlation was observed between the UPDRS and plasma BCAA and EAA in the pre-supplemented PD patients. This study is the first to report that Whey protein supplementation significantly increases plasma reduced glutathione, the reduced to oxidized glutathione ratio, BCAAs and EAAs in patients with PD, together with a concomitant significant reduction of plasma Hcy. However, there were no significant changes in

  1. DSD and Professionalism from a Multilateral View: Supplementing the Consensus Statement on the Basis of a Qualitative Survey

    2012-01-01

    Full Text Available Treatment and support of a child with DSD calls for experience and expertise in diagnosis, surgical techniques, understanding of psychosocial issues, and recognizing and accepting the significance of individual values of children, families, and support groups. The range of what is considered “appropriate” care and treatment is still very broad and critics point at major gaps between ethical guidelines and current clinical practice. Based on a qualitative study with 27 members of multidisciplinary teams and support groups, we supplement the professional consensus statements and current ethical guidelines with 14 requirements from four different perspectives, to characterize more fully the responsible treatment and support of children and families affected by DSD. Overall, our findings highlight the importance of close collaborations between different experts and a shift from the often simplified dispute about genital surgeries to a more holistic perspective with a long-term management strategy, which should serve as a cornerstone not only for clinical practice but also for future research and evaluation studies.

    2017-01-01

    Background : The consumption of fruits, vegetables, and dietary supplements correlate. Most previous studies have aimed to identify the determinants of supplement uses or the distinct features of supplement users; this literature lacks a discussion on dietary supplement consumption as a predictor of fruit and vegetable consumption. Objective : This study examines how dietary supplement consumption correlates with fruit and vegetable consumption by combining scanner data and surveys of Korean household grocery shopping. Methods : Propensity score matching (PSM) is used to identify the relationship between dietary supplement consumption and fruit and vegetable consumption in a household. A logit regression using supplement consumption as the dependent variable is used. Then, the supplement takers (the treatment group) are matched with non-takers (the control group) based on the propensity scores estimated in the logit regression. The fruit and vegetable consumption levels of the groups are then compared. Results : We found that dietary supplement use is associated with higher fruit and vegetable consumption. This supports the health consciousness hypothesis based on attention bias, availability heuristics, the focusing effect, and the consumption episode effect. It rejects the health substitute hypothesis based on economic substitutes and mental accounting. Conclusions : Future research on the health benefits of dietary supplements should address the complementary consumption of fruits/vegetables and their health benefits to avoid misstating the health effects of supplements.

    To identify frequently reported prescription medications and supplements among couples planning pregnancy because there is a lack of descriptive information on these agents in women and men who are trying to conceive. Five hundred one couples enrolled in the Longitudinal Study of Infertility and the Environment, which took place between 2005 and 2009. Participants reported prescription medications as well as prescription and over-the-counter supplements used through interviews at study enrollment and through daily dairies during the 12-month follow-up. We identified prescription medications and supplements prospectively reported by ≥1% of women and men at baseline and from daily journal information grouped into 3-month preconception follow-up intervals while couples tried for pregnancy. The 5 most reported prescription medications among women were levothyroxine (5.8%), cetirizine (2.6%), fluticasone (2.4%), escitalopram (1.8%), and fluoxetine (1.8%) and for men were lisinopril (2.0%), mometasone (2.0%), fexofenadine (1.8%), atorvastatin (1.6%), and montelukast (1.6%). The most reported supplements were multivitamins (63.3%, 43.5%) and fish oil (13.2%, 9.4%) for women and men, respectively, and prenatal vitamins (22.0%) for women. For women during the first 3 months of follow-up, prenatal vitamins (6.0%) and antibiotics (1.2%-2.6%) were among the most frequently started medications. During the next 3 months, clomiphene (4.5%) was the most frequently initiated medication. Couples trying for pregnancy reported a variety of prescription medications and supplements, and they differed by gender. Preconception guidance should address medication and supplement use to avoid potential exposures associated with adverse reproductive and perinatal outcomes.

    In the current automobile market buffeting is one of the customer frequent complaints on luxury cars and SUVs. Buffeting is a low frequency but high level wind noise and makes people inside the vehicle uncomfortable if it lasts for a long period of time. The physical mechanism of buffeting is a complicated phenomenon of aeroacoustic resonance. The aeroacoustic characteristics of buffeting depend on vehicle features and operating conditions. In this paper, a survey of CFD studies on the automotive buffeting is presented. Firstly, several buffeting related concepts, such as Helmholtz resonator, flow over a cavity, shear layer instability and vortex shedding, are reviewed and relevant references are listed. Then, a historic survey of the buffeting investigation is made with emphasis on computational studies. As an example, the buffeting studies at DaimlerChrysler are selected to demonstrate the procedure of CFD simulation for automotive buffeting. The procedure is then validated by the correlation with wind tunnel testing. After that the validated procedure is applied to find solutions for buffeting reduction. Finally, some comments on buffeting studies are addressed. (author)

    Health authorities in numerous countries recommend periconceptional folic acid supplementation to prevent neural tube defects. The objective of this study was to examine the association of dietary folate intake and folic acid supplementation during different periods of pregnancy with the risk of spontaneous preterm delivery (PTD). The Norwegian Mother and Child Cohort Study is a population-based prospective cohort study. A total of 66,014 women with singleton pregnancies resulting in live births in 2002-2009 were included. Folic acid supplementation was self-reported from 26 weeks before pregnancy until pregnancy week 24. At gestational week 22, the women completed a food frequency questionnaire, which allowed the calculation of their average total folate intake from foods and supplements for the first 4-5 months of pregnancy. Spontaneous PTD was defined as the spontaneous onset of delivery between weeks 22+0 and 36+6 (n = 1,755). The median total folate intake was 313 μg/d (interquartile range IQR 167-558) in the overall population and 530 μg/d (IQR 355-636) in the supplement users. Eighty-five percent reported any folic acid supplementation from effect of dietary folate intake or folic acid supplementation on spontaneous PTD. Preconceptional folic acid supplementation starting more than 8 weeks before conception was associated with an increased risk of spontaneous PTD. These results require further investigation before discussing an expansion of folic acid supplementation guidelines.

    Full Text Available High intensity exercise (HI induces oxidative stress. Running for 2400 meters is one of the simple exercise form which can be counted as HI. During HI, increase of oxygen consumption happened in muscle cell resulted in an increase of oxidant level. The aim of the study was to measure the effects of Indonesian green tea supplementation, before and after HI to the level of lipid peroxidation (TBARSMalonyldialdehyde (MDA. The subjects of study were 42 male students from Faculty of Medicine, Universitas Padjadjaran (FMUP and Faculty of Physical Exercise, Indonesia University of Education (FPOK-UPI. The subjects were divided into trained and untrained subject. Subjects were divided into groups using Astrand Harvard step test. The purpose of this test was measuring the level of VO2 max. Blood samples for MDA level were collected at 3 hours before and after high intensity aerobic exercise. Oxidative stress was induced by 2400 meters run. The result showed that green tea supplement-ation was effective to decrease MDA plasma level especially after exercise. Green tea could serve as natural antioxidant resources, which potentially can be used as potential sport supplemental drink.

    The effect of selenium supplementation on recurrent hyperthyroidism caused by Graves' disease is unclear. Our study aimed to assess the efficacy of selenium supplementation therapy on recurrent Graves' disease. Forty-one patients with recurrent Graves' disease were enrolled in this study. All patients received the routine treatment using methimazole (MMI), while patients allocated to the selenium group received additional selenium therapy for 6 months. The influence of selenium supplementation on the concentrations of thyroid stimulating hormone (TSH), anti-TSH-receptor antibodies (TRAb), free thyroxine (FT4), and free triiodothyronine (FT3) were assessed. The remission rate was also compared between 2 groups. There was no obvious difference in the demographic data and the levels of serum FT4, FT3, TSH, and TRAb between the 2 groups at baseline. Both FT4 and FT3 decreased more at 2 months in the selenium group than the controls, while the TSH level increased more in patients receiving selenium supplementation (pGraves' disease. Randomized trials with large number of participants are needed to validate the finding above. © Georg Thieme Verlag KG Stuttgart · New York.

    At the request of the U.S. Department of Energy Office of River Protection, Pacific Northwest National Laboratory (PNNL) conducted a scoping study to investigate supplemental technologies for supplying vertical fluid motion and enhanced mixing in Waste Treatment and Immobilization Plant (WTP) vessels designed for high solids processing. The study assumed that the pulse jet mixers adequately mix and shear the bottom portion of a vessel. Given that, the primary function of a supplemental technology should be to provide mixing and shearing in the upper region of a vessel. The objective of the study was to recommend a mixing technology and configuration that could be implemented in the 8-ft test vessel located at Mid-Columbia Engineering (MCE). Several mixing technologies, primarily airlift circulator (ALC) systems, were evaluated in the study. This technical report contains a review of ALC technologies, a description of the PNNL testing and accompanying results, and recommended features of an ALC system for further study.

    We evaluated the role of dietary iron, heme iron, and supplemental iron on colorectal cancer (CRC) risk in a population-based case-control study in Pennsylvania, including 1005 incident cases and 1062 controls. Diet was assessed through a modified food frequency questionnaire that included supplement use and a meat-specific module. Cases reported intakes for the year before diagnosis, whereas controls reported intakes for the year before interview. Heme iron intake was calculated using a new heme database developed by the US National Cancer Institute. Odds ratios (ORs) and 95% confidence intervals (CIs) were estimated using unconditional logistic regression. After multivariate adjustment, there were no significant associations between heme iron or total iron intake and CRC incidence. Dietary iron intake was inversely associated with CRC among women (OR Q5 vs. Q1=0.45; 95% CI=0.22-0.92), but not among men. Supplemental iron intake of more than 18 mg/day versus none was positively associated with CRC incidence (OR=2.31; 95% CI=1.48-3.59; P-trendconsumption of more than 18 mg/day of supplemental iron may increase risk for CRC.

    Purpose: To investigate the protective effect of L-arginine on the prostate (nonneoplasic) of rats with radiation-induced injury. Methods: Twenty-nine Wistar rats, male adult, allocated into three groups: Control group (C) was not exposed to irradiation (n=10); Radiated group (R) had undergone pelvic irradiation (n=10); Supplemented and radiated group (R+S) had undergone pelvic irradiation plus L-arginine supplementation (n=9). The animals were observed for signs of toxicity. After euthanization, the prostate was dissected under magnification and stained by hematoxylin and eosin to study acinar structures and stained with Picrosirius red for collagen analysis. Results: After radiation exposure, all animals presented diarrhea, but supplementation with L-arginine reduced this effect. The weight gain in the R+S group was significantly higher than in the C and R groups. In the R+S group the collagen density and the prostate acinar area was similar to the R and C groups. Epithelial height was significantly reduced in group R compared with group C (p<0.0001). When comparing the group R+S with R, a statistical difference was observed to be present (p<0.0001). Conclusions: Pelvic radiation promotes systemic effects and some structural modifications in the ventral prostate of rats. These modifications can be prevented by oral supplementation with L-arginine. (author)

    Lay interest in vitamin D and the potential benefits of supplementation is considerable, but little information exists concerning lay knowledge, beliefs and attitudes towards vitamin D to inform public health initiatives and professional guidance. Qualitative focus group study. 58 adults capturing diversity in disease status, gender, age and ethnicity. A large general practice in east London. Many respondents lacked knowledge about vitamin D, including dietary sources and government recommendations. Most were positive about sun exposure, but confused by ambiguous health messages about risks and benefits of sunshine. Medicalised views of vitamin D were prominent, notably from those in favour of supplementation, who talked of "doses", "side effects" and "regular testing." Fortification of food with vitamin D was controversial, with opposing utilitarian (better overall for the majority) and libertarian (freedom to choose) views. Knowledge about vitamin D was limited. Clearer messages are needed about risks and benefits of sun exposure. Testing and supplementation by health professionals, while potentially useful in some high-risk groups, have contributed to a medicalised view of vitamin D. Health policy should address the public's need for clear information on sources and effects of vitamin D, including risks and benefits of sun exposure, and take account of divergent views on fortification. Professional guidance is needed on testing and supplementation to counter inappropriate medicalisation. Published by the BMJ Publishing Group Limited.

    Full Text Available The objective of this study was to understand the usage patterns of dietary supplements among professional athletes in Saudi Arabia. The survey consisted of sixteen questions divided into four categories: use of supplements, reason for consumption of supplements, personal beliefs about supplements, and behavior. The questionnaires were given to the three teams residing in Riyadh: Al Hilal, Al Nasr, and Al-Shabab. Out of the 105 athletes surveyed, we found that only 98 are currently taking dietary supplements and the mean age and standard deviation were 25.74±2.90. The survey results showed a high percentage of athletes (93.3%; n=98 using different dietary supplements throughout the season, 43.8% (n=43 reported using supplements for performance, and 32.6% (n=32 believed in health benefits as a reason for using dietary supplements. Our results showed that a total of 87 (88.7%, 81 (82.6%, and 51 (52.0% athletes are consuming sports drinks, vitamin C, and multivitamins, respectively. Meanwhile, those supplements ranking among the least used included omega 6 (18.6%, creatine (16.3%, and Ginkgo biloba (10.2%. A majority of athletes indicated that their use of supplements was for the purpose of improving their health and performance.

    Full Text Available Abstract Background The widespread use of nutritional supplements among athletes is poorly understood. The prevalence of supplement intake and users' knowledge have been researched independently leading to useful, but disconnected, information on supplement use. Methods The 'UK Sport 2005 Drug Free Survey' data (n = 874 were re-analysed using association [χ2] and 'strength of association' tests [φ], to discover observed incongruencies between self-reported supplement use and the underlying motives. Results are given for test pairs between 'motive for use' [doctor's advice, avoiding sickness, overcoming injuries and enhancement of diet] and each supplement used and these were categorized as strong (φ > .7, intermediate (7 φ > .3 and weak (φ Results The use of selected supplements varied widely as follows: multivitamin (72.7%, vitamin C (70.4%, echinacea (30.8%, iron (29.8%, magnesium (11.0% and ginseng (8.3%. Associations with motive were found in 8 of the 10 test pairs which were expected from literature precedents, however only weak associations exist. Of these, four were associated with avoidance of sickness [iron (χ2 = 11.94, p χ2 = 6.43, p φ = .11, p = .011, vitamin C (χ2 = 54.67, p φ = .32, p χ2 = 40.34, p φ = .28, p χ2 = 7.64, p = .006; φ = .12, p = .006 and multivitamin (χ2 = 9.103, p = .003; φ = .13, p = .003; overcoming injuries with magnesium (χ2 = 6.99, p = .008; φ = .11, p = .008; doctors' advice and iron (χ2 = 35.00, p φ = .25, p = .001. Conclusion These results suggest a lack of understanding regarding supplements and health maintenance, except for vitamin C and echinacea. Furthermore, supplement use is apparently independent of physicians/dieticians' advice, except for iron. This may suggest a widespread circumvention of expert advice in the growing area of supplement use and therefore should be addressed to underscore potential health risks.

    Nutritional supplements are frequently used by horse owners/caregivers to supplement their horse(s) diets. Some work has been done to identify the types of supplements fed and the reasons for doing so; however, this has been predominantly disciple-specific and with little focus on participants' perceptions of supplement testing and regulation. The aim of this study was to gain an insight into the use and perceptions of equine dietary supplements in the Irish equestrian industry. An online survey was designed to ascertain the following information: demographics, types of supplements fed and reasons for use, factors that influenced respondents' choice of supplement, where advice was sought and perceptions of testing and regulation of equine supplements. The survey yielded 134 responses, 70% non-professionals and 30% professionals. A greater percentage of professionals included supplements in their horse(s) diets (98%) compared to non-professionals (86%). Almost 70% of professionals fed more than two supplements, whereas 80% of non-professionals reported to feed only one supplement. Joint supplements were most commonly fed by all respondents (22%) followed by calming supplements (13%). The enhancement of performance (35%) and prevention of joint disorders (34%) were the most common reasons reported by respondents for using a supplement. Over 53% of respondents sought advice on choosing a supplement from their feed merchant, followed by their veterinarian (46%). Veterinary recommendation was given as the most influential factor when choosing a supplement by 90% of respondents, followed by cost (69%). Most (93%) respondents thought that feed supplements had to meet legal standards, with each batch analysed for quality (72%) and the supplement tested on horses before being launched on to the market (92%). This study has identified the main types of supplements used in the Irish equestrian industry along with the reasons for their use. However, it has also highlighted

    Full Text Available Abstract Background Little is known about the prevalence of dietary supplement (DS use in American adolescents. We conducted this study to analyze the prevalence of DS use and factors associated with this use in a national population-based sample. Methods We used data from the 1999 – 2002 National Health and Nutrition Examination Surveys (NHANES for adolescents age 11 to 19. Using weighted logistic regression, we identified demographic and clinical factors associated with the use of any DS, vitamins or minerals, herbs and other DS. Results Among the 5,306 responses representing approximately 36 million Americans 11–19 years old, 27% reported use of one or more DS in the prior month. The most commonly used DS were: multivitamins (16% and vitamin C (6%. In the multivariable analysis, African American [adjusted odds ratio 0.40 (0.31–0.50 95% CI] and Mexican American [0.55 (0.44–0.69] adolescents were less likely to use DS compared with non-Hispanic whites. DS use was more common in those who used prescription medications [1.37 (1.10–1.72] and among those who had a diagnosis of chronic headaches [1.25 (1.04–1.50]. DS use was less common among those reporting fair or poor health status [0.59 (0.40–0.88]. Conclusion Twenty seven percent of American adolescents use DS. DS use is higher among teens that use prescription medications; physicians and pharmacists should be aware of this, ask patients, and check for potential interactions.

    1993-02-01

    We conducted a survey of 624 commercially available supplements targeted towards bodybuilding athletes. Over 800 performance claims were made for these supplements. Supplements include amino acids, boron, carnitine, choline, chromium, dibencozide, ferulic acid, gamma oryzanol, medium chain triglycerides, weight gain powders, Smilax compounds and yohimbine. Many performance claims advertised were not supported by published research studies. In some instances, we found no research to validate the claims; in other cases, research findings were extrapolated to inappropriate applications. For example, biological functions of some non-essential compounds were interpreted as performance claims for the supplements. Claims for others were based on their ability to enhance hormonal release or activity. We suggest that more research be conducted on this group of athletes and their nutritional needs. Furthermore, the effectiveness and safety of supplements merit further investigation.

    Whereas atherogenicity of dietary lipids has been largely studied, relatively little is known about the possible contribution of dietary amino acids to macrophage foam-cell formation, a hallmark of early atherogenesis. Recently, we showed that leucine has antiatherogenic properties in the macrophage model system. In this study, an in-depth investigation of the role of leucine in macrophage lipid metabolism was conducted by supplementing humans, mice, or cultured macrophages with leucine. Macrophage incubation with serum obtained from healthy adults supplemented with leucine (5 g/d, 3 weeks) significantly decreased cellular cholesterol mass by inhibiting the rate of cholesterol biosynthesis and increasing cholesterol efflux from macrophages. Similarly, leucine supplementation to C57BL/6 mice (8 weeks) resulted in decreased cholesterol content in their harvested peritoneal macrophages (MPM) in relation with reduced cholesterol biosynthesis rate. Studies in J774A.1 murine macrophages revealed that leucine dose-dependently decreased cellular cholesterol and triglyceride mass. Macrophages treated with leucine (0.2 mM) showed attenuated uptake of very low-density lipoproteins and triglyceride biosynthesis rate, with a concurrent down-regulation of diacylglycerol acyltransferase-1, a key enzyme catalyzing triglyceride biosynthesis in macrophages. Similar effects were observed when macrophages were treated with α-ketoisocaproate, a key leucine metabolite. Finally, both in vivo and in vitro leucine supplementation significantly improved macrophage mitochondrial respiration and ATP production. The above studies, conducted in human, mice, and cultured macrophages, highlight a protective role for leucine attenuating macrophage foam-cell formation by mechanisms related to the metabolism of cholesterol, triglycerides, and energy production. © 2018 BioFactors, 2018. © 2018 International Union of Biochemistry and Molecular Biology.

    2011-01-01

    Full Text Available Abstract Background Folic acid (FA added to foods during fortification is 70-85% bioavailable compared to 50% of folate occurring naturally in foods. Thus, if FA supplements also are taken during pregnancy, both mother and fetus can be exposed to FA exceeding the Institute of Medicine's recommended tolerable upper limit (TUL of 1,000 micrograms per day (μg/d for adult pregnant women. The primary objective is to estimate the proportion of women taking folic acid (FA doses exceeding the TUL before and during pregnancy, and to identify correlates of high FA use. Methods During 2005-2008, pre-pregnancy and pregnancy-related data on dietary supplementation were obtained by interviewing 539 pregnant women enrolled at two obstetrics-care facilities in Durham County, North Carolina. Results Before pregnancy, 51% of women reported FA supplementation and 66% reported this supplementation during pregnancy. Before pregnancy, 11.9% (95% CI = 9.2%-14.6% of women reported supplementation with FA doses above the TUL of 1,000 μg/day, and a similar proportion reported this intake prenatally. Before pregnancy, Caucasian women were more likely to take FA doses above the TUL (OR = 2.99; 95% = 1.28-7.00, compared to African American women, while women with chronic conditions were less likely to take FA doses above the TUL (OR = 0.48; 95%CI = 0.21-0.97. Compared to African American women, Caucasian women were also more likely to report FA intake in doses exceeding the TUL during pregnancy (OR = 5.09; 95%CI = 2.07-12.49. Conclusions Fifty-one percent of women reported some FA intake before and 66% during pregnancy, respectively, and more than one in ten women took FA supplements in doses that exceeded the TUL. Caucasian women were more likely to report high FA intake. A study is ongoing to identify possible genetic and non-genotoxic effects of these high doses.

    To assess patterns and levels of dietary supplement use among Australian Defence Forces, previously deployed to the Middle East Area of Operations. A cross-sectional study. Participants of a large survey self-completed questions about dietary supplement use, health status, personal and job-related characteristics, and lifestyle factors. Frequency of current use of supplements was assessed in three categories (bodybuilding, energy and weight loss). Middle East Area of Operations post-deployment health survey. Current and ex-serving Australian Defence Force personnel (n 14 032) who deployed to the Middle East between 2001 and 2009. Bodybuilding supplements were used by 17·5 % of participants, energy supplements by 24·5 % and weight-loss supplements by 7·6 %. Overall, 32·3 % of participants used any of these supplements. Bodybuilding and energy supplements were more often used by men, younger persons and those in the Army, while weight-loss supplements were more commonly used by women and Navy personnel. Supplements in all three categories were more commonly used by persons in lower ranks, active service and combat roles. Users of bodybuilding supplements had healthier lifestyles and better health status, while users of energy and weight-loss supplements had less healthy lifestyles and poorer mental and physical health status. Overall, 11·7 % of participants used supplements containing caffeine and 3·6 % used a creatine-containing product. Use of dietary supplements among Australian Defence Force personnel is common, and patterned by lifestyle factors and health status.

    Breastfeeding is fundamental to maternal and child health and is the most cost-effective intervention to reduce child mortality. Pasteurized human donor milk (HDM) is increasingly provided for term newborns requiring temporary supplementation. Few studies examine maternal perspectives on supplementation of term newborns. We conducted semistructured in-person interviews with mothers of term newborns (n = 24) during postpartum hospitalization. Mothers were asked whether they had chosen or would choose to supplement with HDM versus infant formula, if medically indicated, and why. Data were gathered to saturation and analyzed inductively by consensus. Emerging semantic themes were compared between mothers who chose or would choose HDM and those who chose or would choose infant formula. Most mothers had concerns about HDM, including uncertainty regarding screening and substances passed through HDM. Experiences with prior children influenced decision-making. Mothers who chose or would choose HDM (56%, n = 14) praised it as "natural," and some felt suspicious of infant formula as "synthetic." Mothers who chose or would choose infant formula (44%, n = 10) did not know enough about HDM to choose it, and many viewed infant formula as a short-term solution to supply concerns. Mothers unanimously mistrusted online milk purchasing sources, although the majority felt positively about using a friend or family member's milk. Counseling regarding term newborn supplementation should focus on HDM education, specifically on areas of greatest concern and uncertainty such as donor selection, screening, transmission of substances, and mother's milk supply. Research is needed to assess the long-term impact of attitudes and choices on breastfeeding.

    Full Text Available Seriously ill infants often display protein-calorie malnutrition due to the metabolic demands of sepsis and respiratory failure. Glutamine has been classified as a conditionally essential amino acid, with special usefulness in critical patients. Immunomodulation, gut protection, and prevention of protein depletion are mentioned among its positive effects in such circumstances. With the intent of evaluating the tolerance and clinical impact of a glutamine supplement in seriously ill infants, a prospective randomized study was done with nine patients. Anthropometric and biochemical determinations were made, and length of stay in the intensive care unit (ICU, in the hospital, and under artificial ventilation, and septic morbidity and mortality were tabulated. Infants in the treatment group (n=5 were enterally administered 0.3 g/kg of glutamine, whereas controls received 0.3 g/kg of casein during a standard period of five days. Septic complications occurred in 75% of the controls (3/4 versus 20% of the glutamine-treated group (1/5, p<=0.10, and two patients in the control group died of bacterial infections (50% vs. 0%, p<=0.10. Days in the ICU, in the hospital, and with ventilation numerically favored glutamine therapy, although without statistical significance. The supplements were usually well tolerated, and no patient required discontinuation of the program. The conclusion was that glutamine supplementation was safe and tended to be associated with less infectious morbidity and mortality in this high-risk population.

    Full Text Available Aim: An experimental study was conducted on 192-day-old broiler chicks for evaluating the effect of 10% neem leaf extract (NLE supplementationon biochemical parameters in chickens experimentally infected with Escherichia coli O78 at 107 CFU/0.5 ml at 7 days of age. Materials and Methods: The 192-day-old broiler chicks were procured. These chicks were divided into two groups (A and B containing 96 birds each on the 1st day. Diet of all the chicks of Group A was supplemented with 10%NLE in water, whereas chicks of Group B were given feed and water devoid of NLE supplementation throughout the experiment. After rearing for 1 week, chicks of both the groups (A and B were again divided into two subgroups (Group A into A1 and A2 and Group B into B1 and B2 of 54 and 42 birds, respectively. At the age of 7 days all the chicks of groups A1 and B1 were injected with E. coli O78 at 107 CFU/0.5 ml intraperitoneally. Blood samples were collected from six chicks from each group at day 0, 2, 4, 7, 14, 21, 28 days post-infection and serum was separated for biochemical studies. Results: There was a significant increase in serum alanine transaminase (ALT, aspartate transaminase (AST, lactate dehydrogenase (LDH activities, globulin concentration and a decrease in total protein (TP, albumin concentrations, and alkaline phosphatase (ALP activity in both the infected groups. However, the changes in biochemical values, i.e., ALT, AST, LDH, ALP, TP, albumin, and globulin wereof lower magnitude in NLE supplemented group suggesting hepatoprotective and cardioprotective effect of NLE. Conclusions: Fromthe present study, it is reasonable to conclude that significant increase in the value of ALT, AST, LDH, globulin, and significant decrease in the value of ALP, TP, and albumin was of lower magnitude in supplemented infected group (A1 as compared to non-supplemented infected group (B1 suggesting hepatoprotective and cardioprotective effect of NLE.

    Most societies prohibit some market transactions based on moral concerns, even when the exchanges would benefit the parties involved and would not create negative externalities. A prominent example is given by payments for human organs for transplantation, banned virtually everywhere despite long waiting lists and many deaths of patients who cannot find a donor.

In this study we focused on payments for human organs and on another “repugnant” transaction, indoor prostitution, to address two questions: (A) Does providing general information on the welfare properties of prices and markets modify attitudes toward repugnant trades? (B) Does additional knowledge on the benefits of a price mechanism in a specific context affect attitudes toward price-based transactions in another context? By answering these questions, we can assess whether eliciting a market-oriented approach may lead to a relaxation of moral opposition to markets, and whether there is a cross-effect of information, in particular for morally controversial activities that, although different, share a reference to the “commercialization” of the human body. Relying on an online survey experiment with 5,324 U.S. residents, we found no effect of general information about market efficiency, consistent with morally controversial markets being accepted only when they are seen as a solution to a specific problem. We also found some cross-effects of information about a transaction on the acceptance of the other; however, the responses were mediated by the gender and (to a lesser extent) religiosity of the respondent—in particular, women exposed to information about legalizing prostitution reduced their stated support for regulated organ payments.

    Full Text Available A survey was mailed to all institutions in Canada licensed to use radiopharmaceuticals. Questions addressed meal type; mode of preparation; and means, ranges and SD of emptying times. Seventy-eight per cent of 222 facilities responded, including all 55 teaching centres. Eighty-five per cent of teaching and 56% of nonteaching centres perform solid phase gastric emptying studies (GES. The majority use 99mTc sulphur colloid (Tc-SC added to eggs before cooking as the standard meal. Twenty-five per cent of teaching and 21% of nonteaching centres perform liquid phase GES. Most use a watery solution of 111In-diethylenetriamine pentaacetic acid. Gastric emptying for solid phase GES, expressed as time for 50% emptying (mean t½, varied from 42 to 105 mins for centres using the Tc-SC egg meal. Twenty-eight per cent of teaching centres used ±2 SD to define their normal range, 26% used ±1 SD, 6% used ±1.5 SD, and 40% did not know the number of SD used. Twenty per cent of non-teaching centres used ±2 SD, 12% used ±1 SD and 68% did not know how many SD were used. For liquid phase GES, mean t½ varied from 20 to 60 mins. Eighteen per cent of centres used healthy volunteers to establish or validate normal ranges. There is substantial variability among the normal ranges for radionuclide solid and liquid phase GES in both teaching and nonteaching centres across Canada. A minority of facilities have established or validated their own normal ranges in healthy volunteers. There is a need for a more standardized protocol and range of normal, with internal validation by each institution.

    The relation between binge-eating disorder (BED) and suicidality (i.e., suicide ideation, plan, and/or attempt) has not been studied extensively, and it is unknown whether BED is uniquely associated with suicidality when adjusting for comorbid psychopathology. Moreover, the course of suicidality in BED has not been determined and it is unknown whether BED precedes suicidality or vice versa. A total of 10,123 adolescents and 2,980 adults from two nationally representative surveys were administered diagnostic interviews assessing psychopathology and suicidality, as well the retrospectively reported ages of onset. Among adults and adolescents, BED was associated with elevated odds of suicide ideation, plan, and attempt at a univariate level, but BED was not associated with elevated odds of suicidality when adjusting for comorbid psychopathology. Kaplan-Meier estimates of temporal patterns displayed that most adolescents experienced suicidality onset following BED onset, whereas most adults experienced suicidality onset prior to BED onset. BED, comorbid disorders, and suicidality share common factors and interrelations, and individuals with BED and comorbid disorders may be at particularly high risk for suicidal outcomes. The presence of BED in adolescence may serve as a marker for more severe symptomatology that precedes the occurrence of suicidality. Research is needed to understand how eating disorder symptoms, comorbid symptoms, and suicidality affect one another over time. © 2016 Wiley Periodicals, Inc.

    Despite the wealth of evidence linking low income to ill health, there is little information from randomised studies on how much and how quickly these risks can be reversed by improvements in income. To conduct a systematic review of randomised studies of income supplementation, with particular reference to health outcomes. Extensive searches of electronic databases and contact with previous authors. As well as searching for trials that were specifically designed to assess the effects of increased income, studies of winners and losers of lotteries were also sought: if winning is purely chance, such studies are, in effect, randomised trials of increased income. Ten relevant studies were identified, all conducted in North America, mostly in the late 1960s and 1970s. Five trials were designed to assess the effects of income supplementation on workforce participation and randomised a total of 10,000 families to 3-5 years of various combinations of minimum income guarantees and reduced tax rates. Two trials were designed to assess re-offending rates in recently released prisoners and randomised a total of 2400 people to 3-6 months of benefits. One trial was designed to assess housing allowances and randomised 3500 families to three years of income supplements. One trial assessed the health effects of 12 months of income supplementation in 54 people with severe mental illness. Finally, one study compared three groups of people who won different amounts of money in a state lottery. In all these studies the interventions resulted in increases in income of at least one fifth. However, no reliable analyses of health outcome data are available. Extensive opportunities to reliably assess the effects of increases in income on health outcomes have been missed. Such evidence might have increased the consideration of potential health effects during deliberations about policies that have major implications for income, such as taxation rates, benefit policies, and minimum wage

    The popularity of high-protein diets for weight reduction is immense. However, the potential benefits from altering the source of dietary protein rather than the amount is scarcely investigated. In the present study, we examined the effects of fish protein supplement on glucose and lipid metabolism in overweight adults. A total of thirty-four overweight adults were randomised to 8 weeks' supplementation with fish protein or placebo tablets (controls). The intake of fish protein supplement was 3 g/d for the first 4 weeks and 6 g/d for the last 4 weeks. In this study, 8 weeks of fish protein supplementation resulted in lower values of fasting glucose (Pfish protein supplementation compared to controls. Glucose-AUC was decreased after 8 weeks with fish protein supplement compared to baseline (Pfish protein may have beneficial effects on blood levels of glucose and LDL-cholesterol as well as glucose tolerance and body composition in overweight adults. The long-term effects of fish protein supplementation is of interest in the context of using more fish as a protein source in the diet, and the effects of inclusion of fish in the diet of individuals with low glucose tolerance should be evaluated.

    The effect of supplementation with peach palm (Bactris gasipaes H.B.K.), as an alternative source of vit. A, in the regional diet of Manaus, AM, Brazil, in which the pulp was cooked and transformed into flour, was studied. The biological trial involved rats which were depleted in zinc and vitamin A, followed by repletion using the regional diet (RD), RD plus peach palm and RD plus vitamin A. The parameters used to determine the utilization of vitamin A were the vitamin A concentrations in the liver and plasma, and the growth of the animals. The diet was prepared according to the data of Shrimpton and Giugliano for families earning less than two legal minimum salaries. Adult post-partum rats were used, with six male pups each, which received a diet based on casein washed with 1% EDTA, without the addition of zinc or vitamin A for a period of 25 days, for the purpose of obtaining newly-weaned animals which were deficient in Zn and Vit.A. A control group received a diet also based on casein washed with 1% EDTA, but with all the nutrients in the quantities suggested by the Committee on Laboratory Animal Diets. The repletion period of the newly-weaned rats was of 30 days and the experimental design was entirely randomized with four groups of eight rats each. The diet supplementation followed the recommendations of the Committee on Laboratory Animal Diets. At the end of the experiment, it was observed that rats which consumed the diet based on the regional diet of Manaus supplemented with either peach palm or vitamin A showed a significantly greater concentration of vitamin A in the liver, 43.3 +/- 6.5 micrograms/g, 42.0 +/- 4.3 micrograms/g, respectively in relation to the regional diet, 5.5 +/- 1.1 micrograms/g (p < 0.05). The amount of zinc present in the regional diet, 10.7 mg per day, was bioavailable as determined by the concentration of zinc in the femurs. The results suggest that the regional diet of Manaus needs to be supplemented with vitamin A to maintain the

    Several studies have been focusing on the effect of omega-3 polyunsaturated fatty acids on modulation of inflammatory markers in several cardiopathies. Although immunoregulatory dysfunction has been associated to the chronic cardiac involvement in Chagas disease, there is no study examining the effects of omega-3 supplementation in these patients. We investigated the effects of omega-3 PUFAs on markers of inflammation and lipid profile in chronic Chagas cardiomyopathy patients. The present study was a single-center double-blind clinical trial including patients with chronic Chagas cardiomyopathy. Patients were randomly assigned to receive omega-3 PUFAs capsules (1.8g EPA and 1.2g DHA) or placebo (corn oil) during an 8-week period. Cytokines, fasting glucose, lipid, and anthropometric profiles were evaluated. Forty-two patients (23 women and 19 men) were included in the study and there were only two losses to follow-up during the 8-week period. Most of sociodemographic and clinical characteristics were similar between the groups at baseline, except for the cytokines IL-1β, IL-6, IL-8, IL-10, IL-17α, and IFNγ. The omega-3 PUFAs group demonstrated greater improvements in serum triglycerides (-21.1 vs. -4.1; p = 0.05) and IL-10 levels (-10.6 vs. -35.7; p = 0.01) in comparison to controls after 8 weeks of intervention. No further differences were observed between groups. Omega-3 PUFAs supplementation may favorably affect lipid and inflammatory profile in chronic Chagas cardiomyopathy patients, demonstrated by a decrease in triglycerides and improvements on IL-10 concentration. Further studies examining the clinical effects of omega-3 fatty acids supplementation in chronic Chagas cardiomyopathy are necessary. NCT01863576.

    Epidemiological studies have associated increased dietary intake of antioxidants (vitamin C, E, and beta-carotene) in preventing and decreasing the extent of ischemic brain injury. The effect of vitamin C supplementation on functional recovery after stroke has not been studied. In this retrospective, case-control study of 23 patients with ischemic stroke taking vitamin C were identified and matched for age, sex, onset to admission, and admission total functional independence measure (TFIM) with 23 patients with ischemic stroke not taking Vitamin C supplementation. Vitamin C 1000 mg daily was prescribed on admission to our unit mainly to patients who were undernourished (defined as significant weight loss and/or 90% or less ideal body weight for age and sex) and those with pressure sores. The outcome measures were: change in the TFIM, FIM-Cognition (FIM-Cog), and FIM-Motor sub-scores, discharge disposition, and length of stay (LOS). The change in TFIM (20 +/- 13 standard deviation [SD] vs. 26 +/- 6, p = 0.20), FIM-Cog (3 +/- 3 SD vs. 4 +/- 5, p = 0.41), FIM-Motor (15 +/- 11 SD vs. 20 +/- 13, p = 0.21) sub-scores were less in the vitamin C treated group, but these differences did not reach statistical significance. Similarly, no significant differences were found in LOS (21 +/- 9 SD vs. 23 +/- 9, p = 0.59), and discharge disposition (home/institution) (9/10 vs. 13/9, p = 0.60) between the vitamin C and the control groups. This study suggests vitamin C supplementation did not enhance functional recovery in undernourished ischemic stroke patients.

    Full Text Available Lutein is the predominant carotenoid in the developing primate brain and retina, and may have important functional roles. However, its bioaccumulation pattern during early development is not understood. In this pilot study, we investigated whether carotenoid supplementation of infant formula enhanced lutein tissue deposition in infant rhesus macaques. Monkeys were initially breastfed; from 1 to 3 months of age they were fed either a formula supplemented with lutein, zeaxanthin, β-carotene and lycopene, or a control formula with low levels of these carotenoids, for 4 months (n = 2/group. All samples were analyzed by high pressure liquid chromatography (HPLC. Final serum lutein in the supplemented group was 5 times higher than in the unsupplemented group. All brain regions examined showed a selective increase in lutein deposition in the supplemented infants. Lutein differentially accumulated across brain regions, with highest amounts in occipital cortex in both groups. β-carotene accumulated, but zeaxanthin and lycopene were undetectable in any brain region. Supplemented infants had higher lutein concentrations in peripheral retina but not in macular retina. Among adipose sites, abdominal subcutaneous adipose tissue exhibited the highest lutein level and was 3-fold higher in the supplemented infants. The supplemented formula enhanced carotenoid deposition in several other tissues. In rhesus infants, increased intake of carotenoids from formula enhanced their deposition in serum and numerous tissues and selectively increased lutein in multiple brain regions.

    The literature survey for the fractional crystallization study of material from tank 241-S-112 is completed, fulfilling the requirements of the Test Plan for Tank 241-S-112 Fractional Crystallization Study (Herting 2003). Crystallization involves the formation of one or more solid phases from a fluid phase or an amorphous solid phase. It is applied extensively in the chemical industry, both as a purification process and a separation process. The main advantage of crystallization over distillation is the production of substances with a very high purity, at a low level of energy consumption, and at relatively mild process conditions. Crystallization is one of the older operations in the chemical industry; therefore, practical experience can usually be used for the design and operation of industrial crystallizers. In addition, advances in the understanding of crystallization kinetics can be useful in the control, design, and scale-up of industrial crystallizers. Research work is currently underway; e.g., the CrysCODE (Crystallizer Control and Design) project, littu://www.aui.tudelft.nl/uroiect/Cn/scode/crvscode.htm, at the Delft University of Technology, with the goal of improving the performance and controllability of industrial crystallizers by means of better control and improved design methodologies. Recent developments in fluid dynamics and reactor technology (e.g., compartment approaches) have led to a better understanding of processes and scale-up phenomena. The ultimate aim of such research is to develop a knowledge-based design frame for optimization of industrial crystallization units. Development work is in progress on a rigorous design analysis model for the description of the crystallization process as a function of the reactor geometry, crystallization kinetics, and operating conditions. One modeling effort is aimed at improving the predictive crystallizer model by implementing a population balance equation that depends on two variables: the size and

    The airborne magnetic survey is a cost-effective method for regional geological investigation. Most of developed countries use aeromagnetic data as important fundamental information for resources development. The first aeromagnetic survey was conducted in the offshore areas of west and southern Taiwan in 1968 by U.S. Naval Oceanographic Office to help Taiwan finding oil. Later, in 2007, a helicopter-borne magnetic survey was proceed in east Taiwan for underground granite bodies. In order to improve better understanding of deep geological structures associated with the Holocene volcanism in Taiwan, we applied helicopter-borne magnetic technique in northern Taiwan include Tatun Volcano Group (TVG) and Kueishan island in 2013 and 2014 to obtain the distribution information of potential magma chamber as well as hydrothermal pathways along regional geological structures. The most important findings of the high-resolution aeromagnetic dataset since 1960's to 2014 acquired include: (1) the distribution of subsurface igneous rocks and the Curie point depth in Tatun Volcano Group, Keelung Volcano Group, and Kueishantao Volcano; (2) the widely distributed NE high-magnetic belts in northern Taiwan may be associated with NE fractures created by long-term subsidence in this area; (3) the high-magnetic belts in south of Lanyang River which is very different from the magnetic characteristics of the Central Range may imply paleo oceanic plate; (4) the NE high-magnetic belts in Penghu area formed by magma intrusion along NE fractures and the dense and high-magnetic anomalies may be associated with the Miocene basaltic lava overlying on the pre-Tertiary igneous dykes and are widely spread in northern Penghu area. The new aeromagnetic survey techniques help us to investigate the areas with steep terrain or covered by dense vegetation which was difficult to obtain reasonable geological understanding, and also provide an opportunity for us to apply the geothermal energy prospecting.

    The aim of the study was to analyze the effect of selenium supplementation on patients with inflammation receiving PN. This double-blind randomized study included 20 hospitalized patients experiencing an inflammatory process while being fed by PN, who were monitored in three stages: first 72 h (0), day 7 (1), and day 14 (2) of PN. The supplemented patients group (G+S) received 60 μg/d (0.75 μmol) of selenium as selenious acid which was added to the PN bag. The nonsupplemented group (G-S) did not receive selenium. The concentration range of 84 to 100 μg/L (1.07-1.27 μmol/L) was used as a reference of plasma selenium. The study included 20 patients (8 G+S and 12 G-S) mainly diagnosed with cancer and/or sepsis. Most of them were hospitalized in the intensive care unit and were receiving PN for clinical reasons. Plasma selenium was greater in the G+S than in the G-S (P = 0.05) in two stages (0 and 1). Since the start of assessment, C-reactive protein (CRP) levels were elevated; however, there was no statistical difference in CRP values between groups (P > 0.05). There was no significant change of glutathione peroxidase over time or between groups (P > 0.05). The selenium concentration was greater in the G+S than in the G-S, acting independently from CRP behavior. However, supplementation was not enough to reach the reference values.

    Patients with cancer may use botanical dietary supplements (BDS) in an attempt to manage the side effects of chemotherapy, yet evidence about BDS use among patients with cancer is limited. The authors examined trends in BDS use among US adults according to cancer status and patient characteristics. A serial, cross-sectional study was conducted using data from the National Health and Nutrition Examination Survey from 1999 through 2014 (n = 43,644). Self-reported cancer diagnosis history and any BDS use in the preceding 30 days were determined. The prevalence of BDS use was calculated in each cycle for respondents with and without cancer, both overall and by patient characteristics. Simple linear regression models were applied to test for trends in BDS use at a 2-sided P value < .05. Multiple logistic regression models were performed to identify the patient factors associated with BDS use. The results were weighted to represent national estimates. The prevalence of BDS use was greater among participants who had cancer compared with participants who did not have cancer, but trends remained stable during 1999 through 2014 for both groups. Trends in BDS use declined in patients with cancer who were older (P trend  = .047), had a low annual family income (P trend  = .028), and had a lower education level (P trend  = .004). Among the respondents without cancer, trends in BDS use declined in those who were middle-aged (P trend  = .025), non-Hispanic whites (P trend  = .025), those with a lower education level (P trend  = .011), and those who were not receiving prescription medication (P trend  = .036). Patient age, sex, race/ethnicity, income, education, and health conditions were associated with BDS use. The overall use of BDS remained stable during 1999 through 2014 for US adults with and without cancer, but it varied by individual characteristics.

    The aim of this clinical study is to provide scientific evidence for supporting traditional Chinese application and usage to the patients. For this purpose, we tested the ability if Panax ginseng extract to lower oxidative damage to nuclear DNA in human lymphocytes by comparing the effect of cooked Chinese turnip on this effect. Seven healthy subjects (4 males and 3 females from 37 to 60 years) participated two occasions which were at least 2 weeks apart. About 2 mL of fasting blood sample for baseline measurement was taken on arrival. They were requested to ingest the content of 5 ginseng capsules in 200 mL water. The subject remained fasting for 2 h until the second blood sample taken. In the other occasion, the experiment was repeated except a piece of cooked turnip (10 g) was taken with the ginseng extract. The two occasions could be interchanged. Comet assay was performed on two specimens on the same day for the evaluation of lymphocytic DNA damage with or without oxidative stress. For the group with ginseng supplementation, there was a significant decrease in comet score for hydrogen peroxide (H 2 O 2 ) treatment over the 2-h period while no change in DNA damage for unstressed sample. For the group with ginseng together with turnip supplementation, there was no significant difference in comet score for both H 2 O 2 treatment and phosphate-buffered saline treatment. Ginseng extract could reduce DNA damage mediated by H 2 O 2 effectively, but this protection effect was antagonized by the ingestion of cooked turnip at the same time. In the current study, commercial ginseng extract was used for supplementing volunteers. Ginseng extract could protect DNA from oxidative stress in vivo while turnip diminished the protection.

    The structure/function of the cranial nerves is a core topic for dental students. However, due to the perceived complexity of the subject, it is often difficult for students to develop a comprehensive understanding of key concepts using textbooks and models. It is accepted that the acquisition of anatomical knowledge can be facilitated by visualisation of structures. This study aimed to develop and assess a novel cranial nerve animation as a supplemental learning aid for dental students. A multidisciplinary team of anatomists, neuroscientists and a computer scientist developed a novel animation depicting the cranial nerves. The animation was viewed by newly enrolled first-year dental students, graduate entry dental students (year 1) and dental hygiene students (year 1). A simple life scenario employing the use of the cranial nerves was developed using a cartoon-type animation with a viewing time of 3.58 minutes. The animation was developed with emphasis on a life scenario. The animation was placed online for 2 weeks with open access or viewed once in a controlled laboratory setting. Questionnaires were designed to assess the participants' attitude towards the animation and their knowledge of the cranial nerves before and after visualisation. This study was performed before the delivery of core lectures on the cranial nerves. Our findings indicate that the use of the animation can act as a supplemental tool to improve student knowledge of the cranial nerves. Indeed, data indicate that a single viewing of the animation, in addition to 2-week access to the animation, can act as a supplemental learning tool to assist student understanding of the structure and function of cranial nerves. The animation significantly enhanced the student's opinion that their cranial nerve knowledge had improved. From a qualitative point of view, the students described the animation as an enjoyable and useful supplement to reading material/lectures and indicated that the animation was a

    Different types of Ca supplements are available in the local markets of Pakistan. It is sometimes difficult to classify these with respect to their composition. In the present work principal component analysis (PCA) technique was applied to classify different Ca supplements on the basis of their elemental data obtained using instrumental neutron activation analysis (INAA) and atomic absorption spectrometry (AAS) techniques. The graphical representation of principal component analysis (PCA) scores utilizing intricate analytical data successfully generated four different types of Ca supplements with compatible samples grouped together. These included Ca supplements with CaCO/sub 3/as Ca source along with vitamin C, the supplements with CaCO/sub 3/ as Ca source along with vitamin D, Supplements with Ca from bone meal and supplements with chelated calcium.

    Full Text Available Roxanne Crosby-Nwaobi, Philip Hykin, Tunde Peto, Sobha Sivaprasad NIHR Clinical Research Facility, NIHR Moorfields Biomedical Research Centre, London, UK Purpose: The aim of this study was to assess the impact of daily oral supplementation with Macushield (10 mg/d meso-zeaxanthin, 10 mg/d lutein, and 2 mg/d zeaxanthin on eye health in patients with retinal diseases by assessing the macular pigment (MP profile, the visual function, and the quality of life. Methods: Fifty-one patients with various retinal diseases were supplemented daily and followed up for 6 months. The MP optical density was measured using the customized heterochromatic flicker photometry and dual-wavelength autofluorescence. Visual function was evaluated by assessing the change in best corrected visual acuity, contrast sensitivity, and glare sensitivity in mesopic and photopic conditions. Vision-related and general quality of life changes were determined using the National Eye Insititute- Visual Function Questionnaire-25 (NEI-VFQ-25 and EuroQoL-5 dimension questionnaires. Results: A statistically significant increase in the MP optical density was observed using the dual-wavelength autofluorescence (P=0.04 but not with the customized heterochromatic flicker photometry. Statistically significant (P<0.05 improvements in glare sensitivity in low and medium spatial frequencies were observed at 3 months and 6 months. Ceiling effects confounded other visual function tests and quality of life changes. Conclusion: Supplementation with the three carotenoids enhances certain aspects of visual performance in retinal diseases. Keywords: macular pigment optical density, diabetes, central serous retinopathy, age-related macular degeneration

  18. Probiotic supplementation promotes calcification in Danio rerio larvae: a molecular study.

    Directory of Open Access Journals (Sweden)

    Francesca Maradonna

    Full Text Available A growing number of studies have been showing that dietary probiotics can exert beneficial health effects in both humans and animals. We previously demonstrated that dietary supplementation with Lactobacillus rhamnosus - a component of the human gut microflora - enhances reproduction, larval development, and the biomineralization process in Danio rerio (zebrafish. The aim of this study was to identify the pathways affected by L. rhamnosus during zebrafish larval development. Our morphological and histochemical findings show that L. rhamnosus accelerates bone deposition through stimulation of the expression of key genes involved in ossification, e.g. runt-related transcription factor 2 (runx2, Sp7 transcription factor (sp7, matrix Gla protein (mgp, and bone gamma-carboxyglutamate (gla protein (bglap as well as through inhibition of sclerostin (sost, a bone formation inhibitor. Western blot analysis of mitogen-activated protein kinase 1 and 3-(Mapk1 and Mapk3, which are involved in osteoblast and osteocyte differentiation, documented an increase in Mapk1 16 days post fertilization (dpf and of Mapk3 23 dpf in individuals receiving L. rhamnosus supplementation. Interestingly, a reduction of sost detected in the same individuals suggests that the probiotic may help treat bone disorders.

    To compare administrative coverage data with results from household coverage surveys for vitamin A supplementation (VAS) and deworming campaigns conducted during 2010-2015 in 12 African countries. Paired t-tests examined differences between administrative and survey coverage for 52 VAS and 34 deworming dyads. Independent t-tests measured VAS and deworming coverage differences between data sources for door-to-door and fixed-site delivery strategies and VAS coverage differences between 6- to 11-month and 12- to 59-month age group. For VAS, administrative coverage was higher than survey estimates in 47 of 52 (90%) campaign rounds, with a mean difference of 16.1% (95% CI: 9.5-22.7; P < 0.001). For deworming, administrative coverage exceeded survey estimates in 31 of 34 (91%) comparisons, with a mean difference of 29.8% (95% CI: 16.9-42.6; P < 0.001). Mean ± SD differences in coverage between administrative and survey data were 12.2% ± 22.5% for the door-to-door delivery strategy and 25.9% ± 24.7% for the fixed-site model (P = 0.06). For deworming, mean ± SD differences in coverage between data sources were 28.1% ± 43.5% and 33.1% ± 17.9% for door-to-door and fixed-site distribution, respectively (P = 0.64). VAS administrative coverage was higher than survey estimates in 37 of 49 (76%) comparisons for the 6- to 11-month age group and 45 of 48 (94%) comparisons for the 12- to 59-month age group. Reliance on health facility data alone for calculating VAS and deworming coverage may mask low coverage and prevent measures to improve programmes. Countries should periodically validate administrative coverage estimates with population-based methods. © 2017 John Wiley & Sons Ltd.

    High-risk medical devices often undergo modifications, which are approved by the US Food and Drug Administration (FDA) through various kinds of premarket approval (PMA) supplements. There have been multiple high-profile recalls of devices approved as PMA supplements. To characterize the quality of the clinical studies and data (strength of evidence) used to support FDA approval of panel-track supplements (a type of PMA supplement pathway that is used for significant changes in a device or indication for use and always requires clinical data). Descriptive study of clinical studies supporting panel-track supplements approved by the FDA between April 19, 2006, and October 9, 2015. Panel-track supplement approval. Methodological quality of studies including randomization, blinding, type of controls, clinical vs surrogate primary end points, use of post hoc analyses, and reporting of age and sex. Eighty-three clinical studies supported the approval of 78 panel-track supplements, with 71 panel-track supplements (91%) supported by a single study. Of the 83 studies, 37 (45%) were randomized clinical trials and 25 (30%) were blinded. The median number of patients per study was 185 (interquartile range, 75-305), and the median follow-up duration was 180 days (interquartile range, 84-270 days). There were a total of 150 primary end points (mean [SD], 1.8 [1.2] per study), and 57 primary end points (38%) were compared with controls. Of primary end points with controls, 6 (11%) were retrospective controls and 51 (89%) were active controls. One hundred twenty-one primary end points (81%) were surrogate end points. Thirty-three studies (40%) did not report age and 25 (30%) did not report sex for all enrolled patients. The FDA required postapproval studies for 29 of 78 (37%) panel-track supplements. Among clinical studies used to support FDA approval of high-risk medical device modifications, fewer than half were randomized, blinded, or controlled, and most primary outcomes were

    Full Text Available Understanding the medication and supplement use of aging people is critical to ensuring that health service providers in primary care can optimise use of these agents. An increasing number of people with different levels of intellectual disability (ID are living in the community and becoming for the first time substantial users of primary health care services. This, however, brings new challenges that need to be addressed at the primary health care level. We quantified the use of medicines and food supplements and described the associated patterns of morbidity in the two comparable cohorts of aging population with and without intellectual disability.This research aligned participants of 50 years and over who lived in the community from two nationally representative cohorts of older people; those with ID from the Intellectual Disability Supplement (n = 238 and those without ID (n = 8,081 from the Irish Longitudinal Study on Ageing.Data showed that both medication and supplement use in the two groups was prevalent but that those with ID received more of both medications and supplements (e.g. polypharmacy was 39.0% in ID vs. 18.1% in non-ID cohort. Moreover, based on an analysis of the therapeutic groups and medications used that treatment was more intense in the ID cohort (95.8 vs. 7.0 International Non-proprietary Names per 100 participants. Supplement use was almost twice as prevalent in the ID group but substantially less diverse with only 10 types of supplements reported. Morbidity was higher in the ID group and showed a higher prevalence of neurological and mental health disorders.The results highlight that the burden of therapy management and the potential risks in those ageing with ID differs substantially from those ageing without ID. Understanding the medication and supplement use of people aging with intellectual disability (ID is critical to ensuring that health service providers in primary/ambulatory care can optimise use of these

    The VR-1 training reactor operated by the Czech Technical University in Prague is utilized mainly for education of students and training of various reactor staff; however, R&D is also carried out at the reactor. The experimental instrumentation of the reactor can be used for the irradiation experiments and neutron activation analysis. In this paper, the neutron activation analysis (NAA) is used for a study of dietary supplements containing the zinc (one of the essential trace elements for the human body). This analysis includes the dietary supplement pills of different brands; each brand is represented by several different batches of pills. All pills were irradiated together with the standard activation etalons in the vertical channel of the VR-1 reactor at the nominal power (80 W). Activated samples were investigated by the nuclear gamma-ray spectrometry technique employing the semiconductor HPGe detector. From resulting saturated activities, the amount of mineral element (Zn) in the pills was determined using the comparative NAA method. The results show clearly that the VR-1 training reactor is utilizable for neutron activation analysis experiments.

    Full Text Available Nutritional supplements are popular among athletes to improve performance and physical recovery. Protein supplements fulfill this function by improving performance and increasing muscle mass; however, their effect on other organs or systems is less well known. Diet alterations can induce gut microbiota imbalance, with beneficial or deleterious consequences for the host. To test this, we performed a randomized pilot study in cross-country runners whose diets were complemented with a protein supplement (whey isolate and beef hydrolysate (n = 12 or maltodextrin (control (n = 12 for 10 weeks. Microbiota, water content, pH, ammonia, and short-chain fatty acids (SCFAs were analyzed in fecal samples, whereas malondialdehyde levels (oxidative stress marker were determined in plasma and urine. Fecal pH, water content, ammonia, and SCFA concentrations did not change, indicating that protein supplementation did not increase the presence of these fermentation-derived metabolites. Similarly, it had no impact on plasma or urine malondialdehyde levels; however, it increased the abundance of the Bacteroidetes phylum and decreased the presence of health-related taxa including Roseburia, Blautia, and Bifidobacterium longum. Thus, long-term protein supplementation may have a negative impact on gut microbiota. Further research is needed to establish the impact of protein supplements on gut microbiota.

    Statin use is frequently associated with muscle-related symptoms. Coenzyme Q10 supplementation has yielded conflicting results in decreasing statin myopathy. Herein, we tested whether coenzyme Q10 supplementation could decrease statin-associated muscular pain in a specific group of patients with mild-to-moderate muscle symptoms. Fifty patients treated with statins and reporting muscle pain were recruited. The Q10 group (n=25) received coenzyme Q10 supplementation over a period of 30 days (50 mg twice daily), and the control group (n=25) received placebo. The Brief Pain Inventory (BPI) questionnaire was used and blood testing was performed at inclusion in the study and after 30 days of supplementation. The intensity of muscle pain, measured as the Pain Severity Score (PSS), in the Q10 group was reduced from 3.9±0.4 to 2.9±0.4 (PPain Interference Score (PIS) after Q10 supplementation was reduced from 4.0±0.4 to 2.6±0.4 (Pstatin-related muscle symptoms in 75% of patients. The relative values of PSS and PIS significantly decreased (-33.1% and -40.3%, respectively) in the Q10 group compared to placebo group (both Pmuscle enzymes or cholesterol values were found. The present results show that coenzyme Q10 supplementation (50 mg twice daily) effectively reduced statin-related mild-to-moderate muscular symptoms, causing lower interference of statin-related muscular symptoms with daily activities.

    2008-04-05

    Chronic hemodialyzed patients have a low level of aerobic capacity, caused by the pathologies concomitant to renal insufficiency, according with a low level of physical activity. One of the factors that would contribute to this level of aerobic capacity is the L-carnitine deficit on skeletal muscle. However, the value of the supplementation of L-carnitine to improve the physical fitness has been controversial. The objective of this work was to evaluate the effect of the administration of L-carnitine on VO2 max in hemodialyzed patients. A group of 21 patients (20-50 years old) on a program of chronic hemodialysis was studied. During 12 weeks, 13 of them received L-carnitine, 7 men and 6 women, 38.8 (9.5) years old; BMI 24.2 (2.1) Kg/m2; 8 of them received placebo, 4 men and 4 women, 35.8 (11.4) years old; BMI 24.5 (5.8) Kg/m2. There was an increase in VO2 peak on L-carnitine group from 16.3 (2.8) mL x Kg(-1) x min(-1) to 19.5 (3.3) mL x Kg(-1) x min(-1), and the same was seen in the placebo group (increase in VO2 peak from 14.8 (3.8) mL x Kg(-1) x min(-1) to 18.9 (4.8) mL x Kg(-1) x min(-1)). The L-carnitine and placebo groups did not show statistical differences at the end of this study (all values above p > 0.05). In this group of patients, the intravenous supplementation of L-carnitine during 12 weeks did not have an impact on the improvement of the VO2 peak.

    Full Text Available Background/Objectives: Vitamin B12 (VB12 deficiency is a common complication after total gastrectomy which may be associated with megaloblastic anemia and potentially irreversible neurologic symptoms. Intramuscular supplementation of VB12 has been considered the standard treatment, although it is associated with high costs and patient discomfort. Patients/Methods: We performed a prospective uncontrolled study (ACTRN12614000107628 in order to evaluate the clinical and laboratory efficacy of long-term oral VB12 supplementation in patients submitted to total gastrectomy. All patients received daily oral VB12 (1 mg/day and were evaluated every 3 months (clinical and laboratory evaluation: hemoglobin, VB12, total iron, ferritin, and folate. Results: A total of 26 patients were included with a mean age of 64 years (29-79. Patients were included with a mean period of 65 months (3-309 after total gastrectomy. At inclusion time, 17/26 patients were under intramuscular VB12, and 9 had not started supplementation yet. There were normal serum VB12 levels in 25/26 patients (mean VB12 serum levels: 657 pg/mL. The mean follow-up period was 20 (8.5-28 months. During follow-up, all patients had normal VB12 levels and there was no need for intramuscular supplementation. The patient with low VB12 levels had an increase to adequate levels, which remained stable. There were no differences with statistical significance among VB12 levels at 6 (867 pg/mL, 12 (1,008 pg/mL, 18 (1,018 pg/mL, and 24 (1,061 pg/mL months. Iron and folate supplementation was necessary in 21 and 7 patients, respectively. Conclusions: Oral VB12 supplementation is effective and safe in patients who underwent total gastrectomy and should be considered the preferential form of supplementation.

    Primary hyperparathyroidism (pHPT) is associated with decreased bone density and increased fracture risk. A significant number of pHPT patients have low calcium intake and suffer from vitamin deficiency. Thus, we adopted a policy of postoperative supplements with calcium and vitamin D after parathyroid surgery. In this study, we investigated if this policy enhanced the postoperative increase in bone density. Forty-two consecutive patients (83% female) were studied. The first 21 patients received no supplements, whereas the following 21 patients received 1,000 g calcium and 800 IU hydroxy D: -vitamin daily (Ca-D group) for 1 year postoperatively. The patients were monitored with bone density and biochemistry pre- and at 1 year postoperatively. Preoperatively, the patients without vitamin D supplementation (non-Ca-D group) did neither differ in biochemistry, clinical features, nor in bone density from patients in Ca-D group. Postoperatively, there was a tendency that patients in Ca-D group increased their bone density, at all sites measured, in a greater extent than patients that did not receive calcium and vitamin D supplementation. In conclusion, based on our results, it is difficult to give a recommendation of vitamin D supplementation in routine use following surgery for primary hyperparathyroidism. Based on the present data, a calculation of sample size for a future randomized controlled trial is presented.

    Little is known about racial/ethnic and socioeconomic variations in the duration of smoking. The goal of this research was to examine these variations. Data came from the 2003, 2006 and 2007 Tobacco Use Supplement of the Current Population Survey. The analysis was limited to ever-smokers (n = 117,168). The outcome was number of years of daily smoking. Survival analysis was employed to predict smoking duration. American Indians with 32 years had the highest median duration of smoking, followed by Blacks and 'other' races with 30 years, Whites with 28 years and Hispanics with 24 years. The difference in the duration of smoking between Blacks and Whites disappeared after adjusting for poverty. Individuals in poverty had a median duration of smoking of 40 years, while those with a family income of at least three times that of the poverty threshold had a median duration of 22 years. Median duration of smoking was 40 years among individuals without a high-school diploma and 18 years among those with a bachelors or higher degree. This research revealed large variations in smoking duration between racial/ethnic and socioeconomic groups. Longer exposure to tobacco among groups that are already disadvantaged is likely to exacerbate existing health disparities.

The effects of dietary supplementation with perilla seed oil rich in a-linolenic acid (α-LNA, parent n-3 fatty acid, were studied in five patients with asthma. The symptoms of asthma and mean peak flow rates (PFR both early in the morning and in the evening were improved 2 weeks after dietary supplementation and the increases in PFR were significant (P<0.05. The generation of leukotriene B4 (LTB4 by peripheral leukocytes stimulated with the Ca2+ ionophore A23187 was significantly suppressed from 77.6 to 41.6 ng/5Xl06 cells by dietary supplementation (P<0.05. The generation of leukotriene C4 (LTC4 by leukocytes was also significantly suppressed from 64.0 to 38.8 ng/5x106 cells after supplementation with perilla seed oil (P<0.05. These results suggest that dietary supplementation with perilla seed oil is beneficial for the treatment of asthma.

    To determine the effect of soyabean oil supplementation on perivascular inflammation in lungs of adult mice induced by Bisphenol A (BPA). Study Design: An experimental study. Place and Duration of Study: Department of Anatomy, Army Medical College, Rawalpindi, in collaboration with the Animal House, National Institute of Health, Islamabad, from June to November 2016. Methodology:Thirty male and female BALB/c mice were divided into three groups, of 10 animals each. Group A animals served as control. Group B animals were given BPA at a dose of 50 mg/Kg body weight/day. Group C animals were given BPA and soyabean oil at doses of 50 mg/Kg body weight/day and 500 mg/day, respectively. All treatments were given once daily for a period of eight weeks. Animals were dissected 24 hours after receiving the last dose. Lung tissue specimen processing and H and E staining was carried out for routine histological study. Perivascular inflammation was morphometrically graded and statistically analysed using Chi-square test with p<0.05. Results: Grade 2 inflammation was recorded in two (20%) animals and grade 3 perivascular inflammation in 80% specimens in Group B; whereas 20% specimens of Group C had grade 2 inflammation and eight (80%) showed grade 1 inflammation. None of the control animals showed any inflammation. All groups were significantly different at p<0.001. Conclusion: BPA produced perivascular inflammation and con-commitant administration of soyabean oil diet protected against it in rodent. (author)

    This review provides a critical update on human and animal studies investigating the effect of alginate supplementation on appetite regulation, glycaemic and insulinemic responses, and lipid metabolism with discussion of the evidence on potential mechanisms, efficacy and tolerability. Dependent on vehicle applied for alginate supplementation, the majority of animal and human studies suggest that alginate consumption does suppress satiety and to some extent energy intake. Only one long-term intervention trial found effects on weight loss. In addition, alginates seem to exhibit beneficial influence on postprandial glucose absorption and insulin response in animals and humans. However, alginate supplementation was only found to have cholesterol-lowering properties in animals. Several mechanisms have been suggested for the positive effect observed, which involve delayed gastric emptying, increased viscosity of digesta and slowed nutrient absorption in the small intestine upon alginate gel formation. Despite reasonable efficacy and tolerability from the acute or short-term studies, we still realize there is a critical need for development of optimal alginate types and vehicles as well as studies on further long-term investigation on alginate supplementation in humans before inferring that it could be useful in the management of obesity and the metabolic syndrome. © 2012 The Authors. obesity reviews © 2012 International Association for the Study of Obesity.

    Little is known about the supplements use and recreational sport practices in Kazakhstan university students. Therefore, the aim of this study was to ascertain supplements use prevalence and their predictors in this population. Cross-sectional survey of both undergraduate and graduate level students was completed in 2017 et al.-Farabi Kazakh National University, the largest higher institution in the country, from almost all Schools. A 45-item questionnaire was used to record physical activity, supplements use, lifestyle attributes (smoking, alcohol, sleep, etc.) and eating habits, and adjusted regression models were used to verify predictors of supplements use. Of the entire sample of 889 students (70% females), 526 (59%) were practicing recreational physical activity (RPA), and walking, jogging and track and field was the most popular activity type (38%). N  = 151 (29%) students reported the use of any supplement (31% in men and 27% in women), whereas the most popular supplement type were vitamins. Supplement use was most prevalent in swimmers (55%). Age (odds ratio (OR) 1.19 (95% confidence interval (CI) 1.04-1.37), use of fitness tracker (OR 6.26 (95% CI 3.90-10.03)) and low-fat diet (OR 1.95 (95% CI 1.23-3.10)), but not income predicted supplements use in adjusted models. With more than half of students exercising regularly, only less than one-third use supplements with a very strong association with fitness tracker use.

    To date, there is no assessment of more than one survey used for a clinical research study that address subjects with and without symptoms related to accommodative or binocular vision disorders. Thus, the purpose of this study was to investigate two different surveys - CISS and Conlon for the same subject group and analyse also critical visual function parameters. Monocular and binocular accommodative response for 20 subjects was measured for dominant eye with openfield infrared autorefractometer (Shin-Nippon SRW-5000) at three distances (24 cm, 30 cm and 40 cm). Subjects were divided into symptomatic and asymptomatic group using cut off score 21 for CISS and 20 for Conlon survey. We found positive exponential growth relationship between CISS and Conlon scores (R² = 0.7), but separation between symptomatic and asymptomatic group differed significantly depending on which survey was used. We found positive correlation between Conlon score and exophoria at 30 cm (r=0.41, p=0.01) and 24 cm (r=0.27, p=0.03). Relationship between subjective symptoms and following clinical parameters - accommodation lag (r accommodation (r convergence near point (r = 0.26, p < 0.05) were not significant. Our results confirmed that using different subjective symptom surveys can provide different results within the same subject group, therefore we recommend to use surveys as a part of case history and tool to measure patient satisfaction and results of treatment effectiveness instead of using them for clinical trials as a criteria to divide symptomatic and asymptomatic group.

    Based on clues from epidemiology and animal experiments, low vitamin D during early life has been proposed as a risk factor for schizophrenia. The aim of this study was to explore the association between the use of vitamin D supplements during the first year of life and risk of developing schizophrenia. Subjects were drawn from the Northern Finland 1966 Birth Cohort (n=9,114). During the first year of life, data were collected about the frequency and dose of vitamin D supplementation. Our primary outcome measures were schizophrenia, psychotic disorders other than schizophrenia, and nonpsychotic disorders as diagnosed by age 31 years. Males and females were examined separately. In males, the use of either irregular or regular vitamin D supplements was associated with a reduced risk of schizophrenia (Risk ratio (RR)=0.08, 95% CI 0.01-0.95; RR=0.12, 95% CI 0.02-0.90, respectively) compared with no supplementation. In males, the use of at least 2000 IU of vitamin D was associated with a reduced risk of schizophrenia (RR=0.23, 95% CI 0.06-0.95) compared to those on lower doses. There were no significant associations between either the frequency or dose of vitamin D supplements and (a) schizophrenia in females, nor with (b) nonpsychotic disorder or psychotic disorders other than schizophrenia in either males or females. Vitamin D supplementation during the first year of life is associated with a reduced risk of schizophrenia in males. Preventing hypovitaminosis D during early life may reduce the incidence of schizophrenia.

    The accidents that occurred at the Fukushima Daiichi Nuclear Power Plant after the Great East Japan Earthquake on 11 March 2011 have resulted in long-term, ongoing anxiety among the residents of Fukushima, Japan. Soon after the disaster, Fukushima Prefecture launched the Fukushima Health Management Survey to investigate long-term low-dose radiation exposure caused by the accident. Fukushima Medical University took the lead in planning and implementing this survey. The primary purposes of this survey are to monitor the long-term health of residents, promote their future well-being, and confirm whether long-term low-dose radiation exposure has health effects. This report describes the rationale and implementation of the Fukushima Health Management Survey. This cohort study enrolled all people living in Fukushima Prefecture after the earthquake and comprises a basic survey and 4 detailed surveys. The basic survey is to estimate levels of external radiation exposure among all 2.05 million residents. It should be noted that internal radiation levels were estimated by Fukushima Prefecture using whole-body counters. The detailed surveys comprise a thyroid ultrasound examination for all Fukushima children aged 18 years or younger, a comprehensive health check for all residents from the evacuation zones, an assessment of mental health and lifestyles of all residents from the evacuation zones, and recording of all pregnancies and births among all women in the prefecture who were pregnant on 11 March. All data have been entered into a database and will be used to support the residents and analyze the health effects of radiation. The low response rate (<30%) to the basic survey complicates the estimation of health effects. There have been no cases of malignancy to date among 38 114 children who received thyroid ultrasound examinations. The importance of mental health care was revealed by the mental health and lifestyle survey and the pregnancy and birth survey. This long

    To investigate whether oral, long-chain omega-3 (ω-3) essential fatty acid (EFA) supplementation, for 3 months, induces changes to the central corneal sub-basal nerve plexus in dry eye disease and whether nerve alterations correlate with clinical findings. This prospective, comparative study involved the final 12 participants enrolled in a randomised, double-masked, placebo-controlled clinical trial of 60 participants with moderate dry eye disease. Participants received either placebo (olive oil 1500 mg/day; n = 4) or ω-3 EFA supplements (~1000 mg/day eicosapentaenoic acid + ~500 mg/day docosahexaenoic acid; n = 8) for 90 days. The main outcome measure was the mean change in central corneal sub-basal plexus nerve parameters between days one and 90, quantified using in vivo confocal microscopy. Secondary outcomes included mean change in tear osmolarity, corneal dendritic cell density and basal epithelial cell density. Compared with baseline, the reduction in OSDI score and tear osmolarity at day 90 were greater in the ω-3 EFA group than the placebo group (OSDI: ω-3 EFA, mean ± SEM: -15.6 ± 2.8 vs placebo: -2.8 ± 4.1 units, t 5 = 2.6, p = 0.04; tearosmolarity: ω-3 EFA: -22.63 ± 5.7 vs placebo: -8 ± 2.7 mOsmol/L, t 9 = 2.3, p = 0.04). At day 90, corneal total nerve branch density (CTBD: 91.1 ± 8.6 vs 45.1 ± 13.4 branches/mm 2 , F 1,10 = 14, p = 0.004) and corneal nerve branch density on the main fibre (CNBD: 63.4 ± 6.5 vs 27.9 ± 11.5 branches/mm 2 , F 1,10 = 6, p = 0.03) were higher in the ω-3 EFA group compared with placebo. Relative to day 1, CNBD (branches/mm 2 ) increased at day 90 in the ω-3 EFA group (+20.0 ± 9.2, t 8 = 3.2 p = 0.01) compared with placebo (-10.8 ± 3.2). Similar changes were evident for corneal nerve fibre length (CNFL, mm/mm 2 ), which increased from baseline at day 90 in the omega-3 EFA group (+2.9 ± 1.6, t 8 = 3.4 p = 0.01) compared with placebo (-2.7 ± 0.5). There was a negative correlation between CTBD and tear osmolarity

    Full Text Available Background: Hyperhomocysteinemia is an independent risk factor for cardiovascular diseases. The frequency of hyperhomocysteinemia is higher in hemodialysis (HD patients than the general population. The objective of this study is to assess the efficacy of high-dose folic acid supplementation with and without vitamin B12 on lowering plasma total homocysteine (tHcy concentrations in HD patients. Methods: Thirty-six HD patients at Imam Hossein Hospital, Tehran, Iran, who had been given folic acid supplements (5 mg/d for at least 3 months before, were enrolled in this clinical trial. Subjects were also checked for other inclusion and exclusion criteria. The subjects were divided randomly into four groups and underwent two months of supplementation as follows: 5 mg/d oral folic acid + placebo in group one, 5 mg/d oral folic acid + vitamin B12 (1 mg/d orally in group two, 15 mg/d oral folic acid + placebo in group three and 15 mg/d oral folic acid + vitamin B12 (1 mg/d orally in group four. Concentrations of plasma tHcy and serum folic acid and vitamin B12 were measured at baseline and after the supplementation period. Dietary intake of patients was also determined during the supplementation period.Results: Of the folic acid supplemented patients, 27.8% had normal levels of tHcy at baseline and 72.2% had hyperhomocysteinemia. After the supplementation period, plasma tHcy increased by 1.35% in group one and decreased by 6.99%, 14.54% and 30.09% in groups two, three and four respectively. Changes in plasma tHcy and serum vitamin B12 were only significant in group four; however, no significant changes were seen for serum folic acid. The percentage of subjects reaching normal levels of plasma tHcy was 5.6 fold higher in group four than in the reference group. Conclusions: Supplementation with 15 mg/d folic acid together with 1 mg/d oral vitamin B12 is more effective in reducing tHcy levels in HD patients.

    Children with cerebral palsy (CP) have an increased risk of vitamin D (VD) deficiency. Although there are many studies on VD and CP, there is limited information about VD supplementation in these patients. To evaluate the effect of supplementation with a single dose of VD on the plasma concentrations of 25-hydroxy-vitamin-D (25OHD) in children with CP. Prospective-randomised-controlled-trial, including 30 Chilean children (19 males) with CP, median age 9.9 years (6.2-13.5). Clinical and biochemical variables including 25OHD, were recorded (time 0 and 8 weeks). Patients were allocated to the supplemented (S) group receiving 100,000 IU oral D3 at baseline, and compared with the placebo (P) group. Among clinical features are highlighted: gastrostomy (60%), underweight (30%), bed-ridden (93.3%), antiepileptic drugs (70%), and 43.3% used VD metabolism inducing antiepileptics. Baseline biochemical measurements were normal. The 25OHD was insufficient in 4/30 and deficient in 6/30. 25OHD levels were not associated with the variables studied. Eight patients completed the study in the S group, and 10 in P group. The placebo and supplementation groups had no significant difference in baseline variables. Serum calcium, phosphate, and alkaline phosphatase levels at 8 weeks were normal in both groups, with no statistically significant differences. 25OHD in the P group was normal in 6/10, and insufficient+deficient in 4/10, and the S group was normal in all (8/8) (exact Fisher test P=.07). A single dose of 100,000 IU VD could normalise the concentrations of 25OHD after 8 weeks of supplementation in Children with CP, but more studies are required to confirm these results.

    Full Text Available Supplement users (SU make healthy lifestyle choices; on the other hand, SU report more medical conditions. We hypothesised that cod liver oil (CLO consumers are similar to non-supplement users, since CLO use might originate from historical motives, i.e., rickets prevention, and not health consciousness. CLO consumers were studied in order to identify possible confounders, such as confounding by indication. The European Prospective Investigation into Cancer (EPIC investigates causes of chronic disease. The participants were 25,639 men and women, aged 40–79 years, recruited from general practices in Norfolk, East-Anglia (UK. Participants completed questionnaires and a health examination between 1993 and 1998. Supplement use was measured using 7-day diet diaries. CLO was the most common supplement used, more prevalent among women and associated with not smoking, higher physical activity level and more favourable eating habits. SU had a higher occurrence of benign growths and bone-related diseases, but CLO was negatively associated with cardiovascular-related conditions. Although the results of SU characteristics in EPIC-Norfolk are comparable with studies worldwide, the CLO group is different from SU in general. Confounding by indication takes place and will need to be taken into account when analysing prospective associations of CLO use with fracture risk and cardiovascular diseases.

    2014-11-01

    Full Text Available Background: The role of micronutrient status for the incidence and clinical course of cutaneous leishmaniasis is not much studied. Still zinc supplementation in leishmaniasis has shown some effect on the clinical recovery, but the evidence in humans is limited. Objective: To compare biochemical nutritional status in cutaneous leishmaniasis patients with that in controls and to study the effects of zinc supplementation for 60 days. Design: Twenty-nine patients with cutaneous leishmaniasis were treated with antimony for 20 days. Fourteen of them got 45 mg zinc daily and 15 of them got placebo. Biomarkers of nutritional and inflammatory status and changes in size and characteristics of skin lesions were measured. Results: The level of transferrin receptor was higher in patients than in controls but otherwise no differences in nutritional status were found between patients and controls. No significant effects of zinc supplementation on the clinical recovery were observed as assessed by lesion area reduction and characteristics or on biochemical parameters. Conclusions: It is concluded that nutritional status was essentially unaffected in cutaneous leishmaniasis and that oral zinc supplementation administered together with intramuscular injection of antimony had no additional clinical benefit.

    Controlling antioxidant supplementation in athletes involved in studies related to oxidative stress and muscle damage is the key to ensure results. The aim of this study was to confirm through high-performance liquid chromatography (HPLC) analysis whether well-trained individuals lied during a personal interview when asked if they were taking supplements with antioxidants, and how this could affect oxidative stress, muscle damage, and antioxidant response. A total of 94 men, well trained in endurance sports, volunteered in this study. They denied taking any antioxidant supplementation at initial interview. After a HPLC analysis, abnormal α-tocopherol concentrations were detected, probably due to a hidden antioxidant supplementation. Participants were classified into two groups: no evidence of antioxidant supplementation (NS group = α-tocopherol values antioxidant supplementation (S group = α-tocopherol values >80 nmol/mL; n = 19). Lipid peroxidation, muscle damage, antioxidant enzyme activity, and nonenzymatic antioxidant content were analyzed according to this classification. Statistical comparisons were performed using Student's t test. The α-tocopherol concentrations were significantly higher in the S group than in the NS group (MD = 725.01 ± 39.01 nmol/mL; P = 0.001). The S group showed a trend toward lower hydroperoxides than the NS group (MD = 1.19 ± 0.72 nmol/mL; P = 0.071). The S group showed significantly lower catalase activity than the NS group (MD = 0.10 ± 0.02-seg-1 mg-1; P antioxidant supplementation in a personal interview, as they showed high plasmatic α-tocopherol concentrations after HPLC verification. Catalase activity seems to be affected by high α-tocopherol plasma levels. Therefore, we strongly recommend the HPLC analysis as a necessary tool to verify the antioxidant intake and preserve results in studies linking oxidative stress and sport.

    We previously reported that some patients used dietary supplements with their medication without consulting with physicians. Dietary supplements and medicines may interact with each other when used concomitantly, resulting in health problems. An Internet survey was conducted on 2109 people who concomitantly took dietary supplements and medicines in order to address dietary supplement usage in people who regularly take medicines in Japan. A total of 1508 patients (two admitted patients and 1506 ambulatory patients) and 601 non-patients, who were not consulting with physicians, participated in this study. Purpose for dietary supplement use was different among ages. Dietary supplements were used to treat diseases in 4.0% of non-patients and 11.9% of patients, while 10.8% of patients used dietary supplements to treat the same diseases as their medication. However, 70.3% of patients did not declare dietary supplement use to their physicians or pharmacists because they considered the concomitant use of dietary supplements and medicines to be safe. A total of 8.4% of all subjects realized the potential for adverse effects associated with dietary supplements. The incidence of adverse events was higher in patients who used dietary supplements to treat their disease. Communication between patients and physicians is important for avoiding the adverse effects associated with the concomitant use of dietary supplements and medicines. PMID:25894658

    Recently, people have used dietary supplements not only for nutritional supplementation, but also for treatment of their diseases. However, use of dietary supplements to treat diseases, especially with medications, may cause health problems in patients. In this study, we investigated use of dietary supplements in patients in Japan. This survey was conducted from January to December 2012, and was completed by 2732 people, including 599 admitted patients, 1154 ambulatory patients, and 979 healthy subjects who attended a seminar about dietary supplements. At the time of the questionnaire, 20.4% of admitted patients, 39.1% of ambulatory patients, and 30.7% of healthy subjects were using dietary supplements, which including vitamin/mineral supplements, herbal extracts, its ingredients, or food for specified health uses. The primary purpose for use in all groups was health maintenance, whereas 3.7% of healthy subjects, 10.0% of ambulatory patients, and 13.2% of admitted patients used dietary supplements to treat diseases. In addition, 17.7% of admitted patients and 36.8% of ambulatory patients were using dietary supplements concomitantly with their medications. However, among both admitted patients and ambulatory patients, almost 70% did not mention dietary supplement use to their physicians. Overall, 3.3% of all subjects realized adverse effects associated with dietary supplements. Communication between patients and physicians is important to avoid health problems associated with the use of dietary supplements. PMID:25431879

    The purpose of the present study was to evaluate the possible therapeutic effects and the safety of Mangifera indica extract (Vimang tablets, 300 mg) combined with methotrexate (MTX) on reducing disease activity in rheumatoid arthritis (RA). Twenty patients with active RA underwent a year of treatment with MTX (12.5 mg/week) associated to non-steroidal anti-inflammatory drugs (NSAIDs) and/or prednisone (5-10 mg/day) were randomly allocated to the experimental group (n=10), that received the extract supplementation (900 mg/day) or preceding usual treatment (n=10) during 180 days. RA activity was evaluated using the tender and swollen joint counts, erythrocyte sedimentation rate, disease activity score-28 (DAS 28), visual analogue scale (VAS) and health assessment questionnaire (HAQ). Treatment's efficacy was demonstrated with ACR criteria. Only the patients of MTX-Vimang group revealed statistically significant improvement in DAS 28 parameters with respect baseline data but no differences were observed between groups. ACR improvements amounted 80% only in MTX-Vimang group at the 90 days (pVimang group, 100% of patients decreased NSAIDs administration (p<0.01) and 70% of those eradicated gastrointestinal side effects (p<0.01) ensuing of the preceding treatment.

    To evaluate the efficacy of oral antioxidant supplementation in the treatment of patients with dry eye syndrome (DES). A prospective, randomized, double-blinded study compared the effects of an antioxidant supplement (containing anthocyanosides, astaxanthin, vitamins A, C, and E, and several herbal extracts, including Cassiae semen and Ophiopogonis japonicus) with placebo on patients with DES. We assessed dry eye symptoms, visual acuity, Schirmer's test, tear film breakup time, cornea and conjunctiva fluorescein staining, serum anti-SSA/anti-SSB antibodies, and the level of reactive oxygen species (ROS) in tears. The supplementation period was 8 weeks and patients were followed up every 4 weeks for 16 weeks. A linear mixed model was used to compare the groups, while within-group differences were tested by repeated-measures analysis of variance. Forty-three patients, 20 and 23 in treatment and placebo groups, respectively, completed the study. Liver and renal functions were normal. Diastolic blood pressure decreased in the treatment group. There were no significant differences in systolic blood pressure, dry eye symptoms, serum anti-SSA and anti-SSB, visual acuity, intraocular pressure, or fluorescein corneal staining between the groups. Tear film breakup time scores and Schirmer's test without topical anesthesia significantly improved in the treatment group. Tear ROS level differed between the groups and decreased after treatment. Overall subjective impression revealed a significant improvement with treatment compared with placebo. Oral antioxidant supplementations may increase tear production and improve tear film stability by reducing tear ROS. The vegetable-based antioxidant supplement used in this study is safe and can be utilized as an adjuvant therapy to conventional artificial tear therapy for patients with DES.

    Full Text Available Abstract Background Musculoskeletal impairment (MSI is an important cause of morbidity and mortality worldwide, especially in developing countries. Prevalence studies for MSI in the developing world have used varying methodologies and are seldom directly comparable. This study aimed to develop a new tool to screen for and diagnose MSI and to pilot test the methodology for a national survey in Rwanda. Methods A 7 question screening tool to identify cases of MSI was developed through literature review and discussions with healthcare professionals. To validate the tool, trained rehabilitation technicians screened 93 previously identified gold standard 'cases' and 86 'non cases'. Sensitivity, specificity and positive predictive value were calculated. A standardised examination protocol was developed to determine the aetiology and diagnosis of MSI for those who fail the screening test. For the national survey in Rwanda, multistage cluster random sampling, with probability proportional to size procedures will be used for selection of a cross-sectional, nationally representative sample of the population. Households to be surveyed will be chosen through compact segment sampling and all individuals within chosen households will be screened. A pilot survey of 680 individuals was conducted using the protocol. Results: The screening tool demonstrated 99% sensitivity and 97% specificity for MSI, and a positive predictive value of 98%. During the pilot study 468 out of 680 eligible subjects (69% were screened. 45 diagnoses were identified in 38 persons who were cases of MSI. The subjects were grouped into categories based on diagnostic subgroups of congenital (1, traumatic (17, infective (2 neurological (6 and other acquired(19. They were also separated into mild (42.1%, moderate (42.1% and severe (15.8% cases, using an operational definition derived from the World Health Organisation's International Classification of Functioning, Disability and Health

    Full Text Available Introduction: The objective of this study was to analyze the effect of caffeine ingestion in soccer performance, particularly in the countermovement jump test (CMJ. Material and methods: A total of 17 players from a U-19 amateur Spanish team participated in this pilot study. A double-blind placebo-controlled randomized experimental design was used in 2 different sessions (1.5 hour per session separated by 1 week. CMJ was collected at the beginning and at the end of sessions; Rating of Perceived Exertion (RPE was recorded. Players ingested caffeine or placebo at the beginning of session (minute 0 of session, providing a total of 4 mg of caffeine or a placebo per kg of body mass. Side effects from caffeine and placebo ingestions were analyzed. The effect sizes (ES were calculated using values for Cohen’s and Quantitative differences were assessed qualitatively (QA. Results: The jump height with caffeine supplementation at the beginning of training was 37.03 (±3.87 cm and at the end was 39.35 (±4.05 cm, obtaining significant improvements (p<0.05; ES: 0.56; QA: 99/1/0. Significant differences on CMJ at the end of the training session between caffeine and placebo groups were observed (39.35 [±4.05] cm vs. 36.85 [±3.15] cm; p<0.05; ES: 0.65; QA: 0/1/99. Significant differences on RPE between groups were observed. A non-significant tendency to suffer more side effects with caffeine ingestion was obtained. Conclusions: This study shows how the ingestion of 4 mg of caffeine per kg of body mass could be an ergogenic aid to improve soccer performance. However, further studies with bigger soccer players sample would be necessary to refute the present results.

    Objective Lay interest in vitamin D and the potential benefits of supplementation is considerable, but little information exists concerning lay knowledge, beliefs and attitudes towards vitamin D to inform public health initiatives and professional guidance. Design Qualitative focus group study. Participants 58 adults capturing diversity in disease status, gender, age and ethnicity. Setting A large general practice in east London. Results Many respondents lacked knowledge about vitamin D, including dietary sources and government recommendations. Most were positive about sun exposure, but confused by ambiguous health messages about risks and benefits of sunshine. Medicalised views of vitamin D were prominent, notably from those in favour of supplementation, who talked of “doses”, “side effects” and “regular testing.” Fortification of food with vitamin D was controversial, with opposing utilitarian (better overall for the majority) and libertarian (freedom to choose) views. Conclusions Knowledge about vitamin D was limited. Clearer messages are needed about risks and benefits of sun exposure. Testing and supplementation by health professionals, while potentially useful in some high-risk groups, have contributed to a medicalised view of vitamin D. Health policy should address the public's need for clear information on sources and effects of vitamin D, including risks and benefits of sun exposure, and take account of divergent views on fortification. Professional guidance is needed on testing and supplementation to counter inappropriate medicalisation. PMID:26173717

    Duroc and Landrace pigs as well as primary myotubes from these breeds were used to investigate mechanisms behind differences in their response to creatine monohydrate (CMH). Pigs were supplemented with 0, 12.5, 25 or 50g CMH/d for 5 days (n=10 per treatment and breed). Plasma levels of creatine...... increased dose-dependently in both breeds, while muscle-creatine phosphate content increased only in the Duroc pigs. (1)H NMR metabolic profiling showed a tendency towards clustering according to CMH supplementation only among Duroc pigs, revealing a stronger response compared to Landrace pigs....... The abundance of insulin-like growth factor I and myostatin mRNA was decreased by CMH supplementation while that of type 1 IGF-receptor and creatine transporter was unaffected. Protein synthesis, increased in the myotubes from both breeds, indicating protein accretion, but no effect was observed on the m...

    Diarrhoea causes 15% of under-5 mortality in developing countries. Zinc (Zn) stores in the body are known to be depleted during acute diarrhoea. The aim of this study was to evaluate the efficacy of Zn given with standard treatment to children with acute or moderate diarrhoea. In this quasi-unmasked, parallel-group study, we enrolled children with diarrhoea at El-Dorra Paediatric Hospital, Gaza Strip, occupied Palestinian territory. Inclusion criteria were children with more than three unformed stools in the preceding 24 h, duration of diarrhoea up to 72 h, and ability to accept oral fluids or feeds. Recruited children were assigned equally to either oral rehydration salts (control group) or oral rehydration salts plus Zn sulphate (Zn group; 10 mg for children younger than 6 months; 20 mg for children aged 6 months and older). All treatments were taken orally for 14 days. Primary outcomes were duration and frequency of diarrhoea. Secondary outcomes included changes in bodyweight, drugs side-effects, and episodes of any or severe dehydration. Data were analysed with SPSS. Outcome measures were compared with the Mann-Whitney U-test, student's t test, odds ratio, or χ 2 test. The study was approved by the ministry of health and the Helsinki Committee in the Gaza Strip. Parents of the children provided verbally informed consent before participation. We enrolled 140 children (aged 1-120 months). Duration of diarrhoea in the Zn group was shorter than in the control group (2·34 days in the Zn group vs 7·20 days in the control group; pZinc supplementation added to standard treatment with oral rehydration salts was effective and resulted in good treatment of diarrhoea.

    We investigated the effects of supplement identification on exercise performance with caffeine supplementation. Forty-two trained cyclists (age 37 ± 8 years, body mass [BM] 74.3 ± 8.4 kg, height 1.76 ± 0.06 m, maximum oxygen uptake 50.0 ± 6.8 mL/kg/min) performed a ~30 min cycling time-trial 1 h following either 6 mg/kgBM caffeine (CAF) or placebo (PLA) supplementation and one control (CON) session without supplementation. Participants identified which supplement they believed they had ingested ("caffeine", "placebo", "don't know") pre- and post-exercise. Subsequently, participants were allocated to subgroups for analysis according to their identifications. Overall and subgroup analyses were performed using mixed-model and magnitude-based inference analyses. Caffeine improved performance vs PLA and CON (P ≤ 0.001). Correct pre- and post-exercise identification of caffeine in CAF improved exercise performance (+4.8 and +6.5%) vs CON, with slightly greater relative increases than the overall effect of caffeine (+4.1%). Performance was not different between PLA and CON within subgroups (all P > 0.05), although there was a tendency toward improved performance when participants believed they had ingested caffeine post-exercise (P = 0.06; 87% likely beneficial). Participants who correctly identified placebo in PLA showed possible harmful effects on performance compared to CON. Supplement identification appeared to influence exercise outcome and may be a source of bias in sports nutrition. © 2016 John Wiley & Sons A/S. Published by John Wiley & Sons Ltd.

    Full Text Available Many official statistics across the UK Government Statistical Service (GSS are produced using data collected from sample surveys. These survey data are used to estimate population statistics through weighting and calibration techniques. For surveys with complex or unusual sample designs, the weighting can be fairly complicated. Even in more simple cases, appropriate software is required to implement survey weighting and estimation. As with other stages of the survey process, it is preferable to use a standard, generic calibration tool wherever possible. Standard tools allow for efficient use of resources and assist with the harmonisation of methods. In the case of calibration, the Office for National Statistics (ONS has experience of using the Statistics Canada Generalized Estimation System (GES across a range of business and social surveys. GES is a SAS-based system and so is only available in conjunction with an appropriate SAS licence. Given recent initiatives and encouragement to investigate open source solutions across government, it is appropriate to determine whether there are any open source calibration tools available that can provide the same service as GES. This study compares the use of GES with the calibration tool ‘R evolved Generalized software for sampling estimates and errors in surveys’ (ReGenesees available in R, an open source statistical programming language which is beginning to be used in many statistical offices. ReGenesees is a free R package which has been developed by the Italian statistics office (Istat and includes functionality to calibrate survey estimates using similar techniques to GES. This report describes analysis of the performance of ReGenesees in comparison to GES to calibrate a representative selection of ONS surveys. Section 1.1 provides a brief introduction to the current use of SAS and R in ONS. Section 2 describes GES and ReGenesees in more detail. Sections 3.1 and 3.2 consider methods for

  7. Pain and Joy of a Panel Survey on Transport Studies

    Over ten years ago, it was established that the most frequent reason that motivates a panel survey on transport studies is the evaluation of a change in the transportation system, or a specific transportation-planning project, especially when the project involves novel elements. From a statistical viewpoint, a panel survey has the definite advantage to offer more accurate estimatesof changes than cross-sectional surveys for the same sample size. Observing travel patterns of individuals and households overseveral consecutive days, has offered insights into activity scheduling and travel planning. Variability in travel patterns has important policy implications as well, but how much effort is worth to design a panel survey? To evaluate the effects of the transport policies introduced in Madrid during the last five years, a ‘short-long’ panel survey wasbuilt, based on a sample of a Madrid-worker subpopulation most affected by those recent changes in transport policy. The paper describes both the design and construction of the panel based on GPS technology, and presents some results based on an analysis of its two waves; for example, it registered an increment of public transport use and walking trips in 10%. The panel overcomes the known attrition problem thanks to providing incentives, maintaining contact, using the same interviewer for the same respondents, and conducting face-to-face interviews.

    Vitamin and mineral supplement use after a breast cancer diagnosis is common and controversial. Dosages used and the timing of initiation and/or discontinuation of supplements have not been clearly described. We prospectively examined changes in use of 17 vitamin/mineral supplements in the first six months following breast cancer diagnosis among 2,596 members (28% non-white) of Kaiser Permanente Northern California. We used multivariable logistic regression to examine demographic, clinical, and lifestyle predictors of initiation and discontinuation. Most women used vitamin/mineral supplements before (84%) and after (82%) diagnosis, with average doses far in excess of Institute of Medicine reference intakes. Over half (60.2%) reported initiating a vitamin/mineral following diagnosis, 46.3% discontinuing a vitamin/mineral, 65.6% using a vitamin/mineral continuously, and only 7.2% not using any vitamin/mineral supplement before or after diagnosis. The most commonly initiated supplements were calcium (38.2%), vitamin D (32.01%), vitamin B6 (12.3%) and magnesium (11.31%); the most commonly discontinued supplements were multivitamins (17.14%), vitamin C (15.97%) and vitamin E (45.62%). Higher education, higher intake of fruits/vegetables, and receipt of chemotherapy were associated with initiation (p-values <0.05). Younger age and breast-conserving surgery were associated with discontinuation (p-values <0.05). In this large cohort of ethnically diverse breast cancer patients, high numbers of women used vitamin/mineral supplements in the 6 months following breast cancer diagnosis, often at high doses and in combination with other supplements. The immediate period after diagnosis is a critical time for clinicians to counsel women on supplement use

    Full Text Available Background and Objective: Bisphenol A is a well-known industrial compound which is widely used in producing plastic throughout the world. Containers made with these plastics may expose people to small amounts of bisphenol A in food and water and cause adverse effects on human health. In this study, the effect of commercial probiotic formulations on reduction of bisphenol A in aqueous solution is investigated.Materials and Methods: One dose of six types of commercial mixtures of probiotic strains were added to a certain amount of bisphenol A in saline basal medium at 37°C. During a 24 h treatment with probiotics, samples were taken from the environments at different times and prepared for further analysis with enzyme-linked immunosorbent assay. The experimental framework was set up in a way that compares formulations and determines the most efficient strains for bisphenol A reduction. In addition, the effect of peripheral conditions such as pH and temperature were also studied.Results and Conclusion: Multi-strain probiotics had an impressively high performance in bio-removal of bisphenol A from aqueous solutions. Up to 80% of bisphenol A concentration was decreased during the first hour of treatment in almost all trials. Among them, the synergy of Lactobacillus acidophilus and Lactobacillus plantarum strains were the most successful. On the other hand, mixture of probiotics had more persistent effect and robust binding ability than single strains. Finally, it can be expected that regular usage of probiotic supplementation with special mixture of strains can suppress the harmful effects of bisphenol A.Conflict of interest: The authors declare no conflict of interest.

    Full Text Available The aim of the study was to identify the effect of supplementation of various forms of zinc on the ruminal mucosa and dimensions of ruminal papillae in 6-month-old goat kids. The experimental period lasted from weaning to slaughter (4 months. All 20 kids divided into four groups of five animals, were fed with the same feeding dose, which was different only in the quantity and form of zinc. Control group was without additional zinc supplementation (group A, the other groups were supplemented with zinc in the form of ZnO (group B, zinc in the form of chelate (group C and zinc in the form of lactate (group D. Samples for histopathological and morphometric examination were collected after the slaughter of all animals from the bottom of saccus ruminis ventralis everytime from the same place. Significant differences were reported within the comparison of the length of ruminal papillae between groups B and C (P = 0.026 and B and D (P = 0.040, within the comparison of the width of ruminal papillae between groups A and D (P = 0.020 and within the comparison of the intensity of keratinisation of the mucosa of ruminal papillae between groups A and B (P = 0.034, A and C (P = 0.038 and A and D (P = 0.001. Histopathological and morphometric examination of ruminal mucosa indicated that the ruminal papillae of kids supplemented with zinc in the form of ZnO (group B were better developed compared to the other groups. This result indicates better utilisation of the supplemented zinc in the form of ZnO.

    To report the prevalence of dietary supplement use in a random sample of US infants 4 to 24 months of age, and to compare demographic characteristics, usual nutrient intakes, and food patterns of supplement users and nonusers. Data from 24-hour recalls collected for the 2002 Feeding Infants and Toddlers Study were analyzed. Recalls included nutrient contributions from dietary supplements as well as all foods and beverages. We estimated usual energy and nutrient intakes of supplement users and nonusers, as well as the prevalence of nutrient adequacy and excess in the two groups. We also compared demographic characteristics and food patterns of supplement users and nonusers and, for supplement users, estimated the proportion of total intake provided by foods and the proportion provided by supplements. A national random sample of 3,022 infants and toddlers age 4 to 24 months, including 430 vitamin and/or mineral supplement users and 2,592 nonusers. We compared means, percentile distributions, and proportions by age and supplement subgroup, and applied the Dietary Reference Intakes to assess usual nutrient intakes. We conducted regression analysis to determine which population characteristics predict the use of dietary supplements in this population. Overall, 8% of infants age 4 to 5 months received some type of dietary supplement. The prevalence of supplement use increased with age, to 19% among infants 6 to 11 months and 31% among toddlers 12 to 24 months. The vast majority of supplement users (97%) received only one type of supplement, most commonly a multivitamin and/or mineral supplement. Vitamin/mineral supplement use among infants and toddlers was associated with being a first-born child and being reported by the primary caretaker as being a picky eater. Characteristics that were independent predictors of supplement use were living in the Northeast, being male, and living in a household with fewer children. We found no significant differences between supplement

    The “subject property” is comprised of a parcel of land within the Kirtland Military Reservation, Bernalillo County, New Mexico, as shown on the map in Appendix B of this document. The land requirement for the parking lot addition to the 9940 Main Complex is approximately 2.7 acres. The scope of this Supplemental Environmental Baseline Survey (SEBS) is for the parking lot addition land transfer only. For details on the original 9940 Main Complex see Environmental Baseline Survey, Land Use Permit Request for the 9940 Complex PERM/0-KI-00-0001, August 21, 2003, and for details on the 9940 Complex Expansion see Environmental Baseline Survey, Proposed Land Use Permit Expansion for 9940 DETS Complex, June 24, 2009. The 2.7-acre parcel of land for the new parking lot, which is the subject of this EBS (also referred to as the “subject property”), is adjacent to the southwest boundary of the original 12.3- acre 9940 Main Complex. No testing is known to have taken place on the subject property site. The only activity known to have taken place was the burial of overhead utility lines in 2014. Adjacent to the subject property, the 9940 Main Complex was originally a 12.3-acre site used by the Department of Energy (DOE) under a land use permit from the United States Air Force (USAF). Historical use of the site, dating from 1964, included arming, fusing, and firing of explosives and testing of explosives systems components. In the late 1970s and early 1980s experiments at the 9940 Main Complex shifted toward reactor safety issues. From 1983 to 1988, fuel coolant interaction (FCI) experiments were conducted, as were experiments with conventional high explosives (HE). Today, the land is used for training of the Nuclear Emergency Response community and for research on energetic materials. In 2009, the original complex was expanded to include four additional 20-acre areas: 9940 Training South, 9940 Training East, T-Range 6, and Training West Landing Zone. The proposed use of

    Diabetes is a serious disease affects human health. Diabetes in advanced stages is accompanied by general weakness and alteration in fats and carbohydrates metabolism. Recently there are some scientific trends about the usage of camel milk (CM) in the treatment of diabetes and its associated alterations. CM contains vital active particles with insulin like action that cure diabetes and its complications but how these effects occur, still unclear. Seventy-five adult male rats of the albino type divided into five equal groups. Group 1 served as a negative control (C). Group 2 was supplemented with camel milk (CM). Diabetes was induced in the remaining groups (3, 4 and 5). Group 3 served as positive diabetic control (D). Group 4 served as diabetic and administered metformin (D+MET). Group 5 served as diabetes and supplemented with camel milk (D+CM). Camel milk was supplemented for two consecutive months. Serum glucose, leptin, insulin, liver, kidney, antioxidants, MDA and lipid profiles were assayed. Tissues from liver and adipose tissues were examined using RT-PCR analysis for the changes in mRNA expression of genes of carbohydrates and lipid metabolism. Pancreas and liver were used for immunohistochemical examination using specific antibodies. Camel milk supplementation ameliorated serum biochemical measurements that altered after diabetes induction. CM supplementation up-regulated mRNA expression of IRS-2 , PK , and FASN genes, while down-regulated the expression of CPT-1 to control mRNA expression level. CM did not affect the expression of PEPCK gene. On the other hand, metformin failed to reduce the expression of CPT-1 compared to camel milk administered rats. Immunohistochemical findings revealed that CM administration restored the immunostaining reactivity of insulin and GLUT-4 in the pancreas of diabetic rats. CM administration is of medical importance and helps physicians in the treatment of diabetes mellitus.

    To study the effect of iron supplementation during pregnancy on epiphyseal growth plate of Sprague dawley rat pups. Study Design: Laboratory based randomized control trial. Place and Duration of Study: This study was conducted at Department of Anatomy, Army Medical College Rawalpindi in collaboration with National Institute of Health (NIH) Islamabad, from Mar 2016 to Nov 2016. Material and Methods: Eight female and two male Sprague Dawley rats, 3-4 months old were selected and divided into two groups and kept for breeding. Pregnant rats were divided into two groups. Four pregnant rats in each group. Group A1was control group and group B1 was experimental group. Iron supplementation was given once daily throughout pregnancy till the time of delivery. Iron was given to the experimental group in syrup form (Sytron syrup containing iron as sodium feredetate). Each 5ml of sytron syrup contains 27.5mg of elemental iron content1. The dose was mixed in water given to the animal. Maternal body weight (wt.) was recorded at the start and the end of experiment. As the rat pups were born, they were weighed and euthanized. Right femur of each rat pup was removed for the epiphyseal plate analysis. It was processed, embedded and stained with Hematoxylin and Eosin, Perl's stain for histological study. Hypertrophy and proliferative zone length were histologically and statistically analyzed. Results: Height of hypertrophy and proliferative zone was measured. Mean values of the heights of two zones were taken. Heights of hypertrophy and proliferative zones were considerably decreased in group B1 as compared to groups A1. Conclusion: Indiscriminate iron supplementation to the rats throughout pregnancy without checking serum iron levels can disturb the longitudinal growth of epiphyseal plate of femur. The height of the hypertrophy zone and proliferative zone was significantly reduced in iron supplementation group as compared to the control group. (author)

This is an institutional review board-exempt anonymous email survey of 523 members of the New England Roentgen Ray Society. In addition to radiologist demographics, survey questions addressed radiologist knowledge of breast density legislation, knowledge of breast density as a risk factor for breast cancer, recommendations for supplemental screening, and perceived practice changes resulting from density notification legislation. Of the 523 members, 96 responded, yielding an 18% response rate. Seventy-three percent of respondents practiced in a state with breast density legislation. Sixty-nine percent felt that breast density notification increased patient anxiety about breast cancer, but also increased patient (74%) and provider (66%) understanding of the effect of breast density on mammographic sensitivity. Radiologist knowledge of the relative risk of breast cancer when comparing breasts of different density was variable. Considerable confusion and controversy regarding breast density persists, even among practicing radiologists. Copyright © 2017 The Association of University Radiologists. Published by Elsevier Inc.

    Objective To examine if children use supplements to fill gaps in nutritionally inadequate diets or whether supplements contribute to already adequate or excessive micronutrient intakes from foods. Study design Data were analyzed for children (2–18 y) from the NHANES 2003–2006, a nationally representative, cross-sectional survey (n=7,250). Diet was assessed using two 24-hour recalls, and dietary supplement use was assessed with a 30-day questionnaire. Results Prevalence of supplements use was 21% (Supplement users had higher micronutrient intakes than nonusers. Calcium and vitamin D intakes were low for all children. Inadequate intakes of phosphorus, copper, selenium, folate, and vitamins B-6 and B-12 were minimal from foods alone among 2–8 y olds. However, among 9–18 y olds, a higher prevalence of inadequate intakes of magnesium, phosphorus, and vitamins A, C, and E were observed. Supplement use increased the likelihood of intakes above the Upper Tolerable Intake Level for iron, zinc, copper, selenium, folic acid, and vitamins A and C. Conclusions Even with the use of supplements, more than a one-third of children failed to meet calcium and vitamin D recommendations. Children 2–8 y had nutritionally adequate diets regardless of supplement use. However, in children older than 8 y dietary supplements added micronutrients to diets that would have otherwise been inadequate for magnesium, phosphorus, vitamins A,C, and E. Supplement use contributed to the potential for excess intakes of some nutrients. These findings may have implications for reformulating dietary supplements for children. PMID:22717218

    The known use of performance enhancing agents by athletes has occurred throughout history. In the 1960s and 1970s steroids and amphetamines were the supplements most often used. Now athletes are turning to supplements that are either natural or stimulate the release of natural hormones. The purpose of this study is to evaluate the prevalence of use of nutritional supplements among high school football and volleyball players. This study surveyed 495 male football players and 407 female volleyball players from 20 high schools in Northwest Iowa. These athletes completed anonymous surveys and returned them to their coaches. Results showed that 8% of the male athletes and 2% of the female athletes were using supplementation. Supplements used included creatine, androstiendione, HMB, amino acids, DHEA, phosphogen, weight gainer 1850, Tribulus, muscle plus, multivitamins, calcium, GABA, and Shaklee Vita Lea and Physique.

    Full Text Available The human gut microbiota is an important environmental factor for human health with evolutionarily conserved roles in immunity, metabolism, development, and behavior of the host. Probiotic organisms are claimed to offer several functional properties including stimulation of immune system. The purpose of this study is to investigate the effects of a probiotic supplementation on adult volunteers who have contracted the common cold four or more times in the past year. This study is a single center, double-blind, randomized, controlled, prospective trial. Subjects received a probiotic drink containing Lactobacillus paracasei (at least 3 × 107 colony forming units (CFU ml−1, Lactobacillus casei 431® (at least 3 × 107 CFU ml−1 and Lactobacillus fermentium PCC® (at least 3 × 106 CFU ml−1 or an identical placebo without probiotics for a 12-week study period. The consumption of probiotics significantly reduced the incidence of upper respiratory infection (p < 0.023 and flu-like symptoms with an oral temperature higher than 38 °C (p < 0.034 as compared to the placebo group. Subjects that consumed probiotics demonstrated a significantly higher level of IFN-γ in the serum (p < 0.001 and sIgA in the gut (p < 0.010 as compared to the placebo group and a significant higher level of serum IFN-γ (p < 0.001 and gut sIgA (p < 0.001 as compared to their baseline test results. In contrast, there were no significant differences in the serum IL-4, IL-10, IgA, IgG or IgM between the probiotics and the placebo groups. Results of this study demonstrated that probiotics were safe and effective for fighting the common cold and influenza-like respiratory infections by boosting the immune system.

    Full Text Available Aim: The present study was conducted to evaluate the effects of neem leaf extract (NLE supplementation on immunological response and pathology of different lymphoid organs in experimentally Escherichia coli challenged broiler chickens. Materials and Methods: For this study, we procured 192-day-old broiler chicks from local hatchery and divided them into Groups A and Group B containing 96 birds each on the first day. Chicks of Group A were supplemented with 10% NLE in water, whereas chicks of Group B were not supplemented with NLE throughout the experiment. At 7th day of age, chicks of Group A were divided into A1 and A2 and Group B into B1 and B2 with 54 and 42 chicks, respectively, and chicks of Groups A1 and B1 were injected with E. coli O78 at 107 colony-forming units/0.5 ml intraperitoneally. Six chicks from each group were sacrificed at 0, 2, 4, 7, 14, 21, and 28 days post infection; blood was collected and thorough post-mortem examination was conducted. Tissue pieces of spleen and bursa of Fabricius were collected in 10% buffered formalin for histopathological examination. Serum was separated for immunological studies. Result: E. coli specific antibody titer was significantly higher in Group A1 in comparison to Group B1. Delayed-type hypersensitivity response against 2,4 dinirochlorobenzene (DNCB antigen was significantly higher in Group A1 as compared to Group B1. Pathological studies revealed that E. coli infection caused depletion of lymphocytes in bursa of Fabricius and spleen. Severity of lesions in Group A1 was significantly lower in comparison to Group B1. Conclusion: 10% NLE supplementation enhanced the humoral as well as cellular immune responses attributed to its immunomodulatory property in experimentally E. coli infected broiler chicken.

  3. Enabling students to learn: Design, implementation and assessment of a supplemental study strategies course for an introductory undergraduate biology course

    Science.gov (United States)

    Sriram, Jayanthi Sanjeevi

    Attrition in the STEM disciplines is a national problem and one of the important reasons for this is student experiences in introductory courses. A myriad of factors influence students' experiences in those courses; inadequate student preparation is one of the most cited reasons. Incoming freshmen often lack the learning strategies required to meaningfully learn and succeed in college courses. Unfortunately, the instructors have limited time and/or have little experience in teaching learning strategies. In this paper, the design, implementation, and evaluation of a Supplemental Course (SC) model that emphasizes learning strategies is presented. SC was offered concurrently with the introductory biology courses for four consecutive semesters (fall 2011 to spring 2013); for 10 weeks in fall 2012 and 7 weeks in the other semesters at Miami University. 10 weeks SC began earlier in the semester than the shorter SC. This study evaluated the effects of the SC on students' (1) performance in the introductory biology course, (2) perceived changes in self-regulation and social support, and (3) experiences in the introductory biology course before, during, and after participation in the SC. A mixed methods approach was used to address these goals. A pre-post survey was administered to obtain students' use of self-regulation strategies and social-support data. Quantitative methods were utilized to analyze content exam grades and changes in self-regulation strategies and social-support. To explore the experiences of the students, semi-structured interviews were conducted, followed by analysis using grounded theory. The findings reveal that participants of the longer duration SC (with an earlier start date) significantly improved in content exam performance, perceived use of self-regulation strategies, and social support compared to the non-participants. Participants of the shorter duration SC (with a later start date) did not significantly improve in content exam performance

    Recently we demonstrated an increased 2,3-diphosphoglycerate (2,3-DPG) erythrocyte concentration in rat pups subjected to nucleotide-enriched artificial feeding. The present study was carried out to test the hypothesis that a possible increase in 2,3-DPG concentration can also be obtained in human neonates who are fed nucleotide-enriched formula. Preterm neonates born or referred to the neonatal intensive care unit of the G. Gaslini Hospital, Genoa University, with a gestational age >30 weeks and <37 weeks were enrolled in our randomized trial. Recruitment took place within 48-72 hours from birth. Only newborns of mothers deciding not to breast-feed were eligible to be randomized for the supplemented group (FN) or non-supplemented group (RF). Breast-fed newborns were considered the control group (C). The study window (for supplementation and blood samples) was restricted to the first two weeks following birth (from the 2nd (t1) to the 16th (t2) day of life). At the end of our study, only 21 neonates were eligible for statistical analysis. The stimulating action of dietary nucleotides on 2,3-DPG concentration failed to be demonstrated; increases in 2,3-DPG concentration that were observed in newborns fed with nucleotide supplemented formula (FN) were comparable to those observed in newborns fed with regular formula (RF) and breast-fed newborns. The EC recommendation for the amount of nucleotides allowed in formula milk does not seem to be high enough to have positive effects on 2,3-DPG synthesis. Whether this possible 'pharmacological' effect can be achieved by a higher intake of ingested nucleotides and/or a change in the proportions of single nucleotides contained in milk formulas remain interesting end points to be elucidated.

    In previous study, we demonstrated a new method to prepare polymeric fiber adsorbents via a chemical-grafting method, namely atom-transfer radical polymerization (ATRP), and identified parameters affecting their uranium adsorption capacity. However, ATRP chemical grafting in the previous study still utilized conventional radiation-induced graft polymerization (RIGP) to introduce initiation sites on fibers. Therefore, the objective of the present study is to perform survey study of trunk fiber materials for direct ATRP chemical grafting method without RIGP for the preparation of fiber adsorbents for uranium recovery from seawater.

    The amphetamine isomer β-methylphenylethylamine (BMPEA) was first synthesized in the early 1930s, but its efficacy and safety in humans has not been studied. Recently, the United States Food and Drug Administration (FDA) detected BMPEA in dietary supplements labelled as containing Acacia rigidula. Over a year after the FDA reported its findings, we analyzed Acacia rigidula dietary supplements to determine if BMPEA had been removed. Supplements were analyzed using liquid chromatography-quadrupole time-of-flight mass spectrometry. Diluted methanolic extract from each supplement was run three times and each data set obtained was analyzed using Agilent MassHunter Qualitative Analysis. The presence of BMPEA was confirmed by accurate mass, retention time and mass spectra match against a reference standard. Quantification of BMPEA was determined using an eight-point calibration curve of spiked standard to a matrix blank. Twenty-one brands of Acacia rigidula supplements were analyzed. More than half (11/21; 52.4%) of the Acacia rigidula supplement brands contained BMPEA. The stimulant was present at quantities such that consumers following recommended maximum daily servings would consume a maximum of 93.7 mg of BMPEA per day. Consumers of Acacia rigidula supplements may be exposed to pharmacological dosages of an amphetamine isomer that lacks evidence of safety in humans. The FDA should immediately warn consumers about BMPEA and take aggressive enforcement action to eliminate BMPEA in dietary supplements. Copyright © 2015 John Wiley & Sons, Ltd.

    Full Text Available The sector of functional products has top-priority meaning – it is the most convenient and natural form of introduction and enrichment of the human organism with vitamins, mineral substances, microelements and other components. Attraction into the branch of raw materials of non-milk origin – fish supplements and substitutes of butterfat – served the basis of technology development of processed cheese products of combined content, which in accordance with acting terminology are called processed cheese products. The technology of processed cheese products allows easily regulating their content by introduction of corresponding supplement that facilitates obtainment of product with set properties and content. Inclusion of meat and fish as the raw materials in the processed cheese content results in enrichment of the product with macro- and microelements, unsaturated fatty acids, except for regulation of fatty acid content of cheese products is executed by substitution of butterfat by butterfat substitute.

    Components present in the diet, L-carnitine, choline, and betaine are metabolized by gut microbiota to produce metabolites such as trimethylamine-N-oxide (TMAO) that appear to promote cardiovascular disease in chronic kidney disease (CKD) patients. The objective of this pilot study was to evaluate the effects of probiotic supplementation for 3 months on plasma TMAO levels in CKD patients on hemodialysis (HD). A randomized, double-blind trial was performed in 21 patients [54.8 ± 10.4 years, nine men, BMI 26.1 ± 4.8 kg/m 2 , dialysis vintage 68.5 (34.2-120.7) months]. Ten patients were randomly allocated to the placebo group and 11 to the probiotic group [three capsules, totaling 9 × 10 13 colony-forming units per day of Streptococcus thermophilus (KB19), Lactobacillus acidophilus (KB27), and Bifidobacteria longum (KB31). Plasma TMAO, choline, and betaine levels were measured by LC-MS/MS at baseline and after 3 months. While TMAO did not change after probiotic supplementation, there was a significant increase in betaine plasma levels. In contrast, the placebo group showed a significant decrease in plasma choline levels. Short-term probiotic supplementation does not appear to influence plasma TMAO levels in HD patients. Long-term studies are needed to determine whether probiotics may affect TMAO production in CKD patients.

    Taurine, the most abundant, semiessential, sulfur-containing amino acid, is well known to lower blood pressure (BP) in hypertensive animal models. However, no rigorous clinical trial has validated whether this beneficial effect of taurine occurs in human hypertension or prehypertension, a key stage in the development of hypertension. In this randomized, double-blind, placebo-controlled study, we assessed the effects of taurine intervention on BP and vascular function in prehypertension. We randomly assigned 120 eligible prehypertensive individuals to receive either taurine supplementation (1.6 g per day) or a placebo for 12 weeks. Taurine supplementation significantly decreased the clinic and 24-hour ambulatory BPs, especially in those with high-normal BP. Mean clinic systolic BP reduction for taurine/placebo was 7.2/2.6 mm Hg, and diastolic BP was 4.7/1.3 mm Hg. Mean ambulatory systolic BP reduction for taurine/placebo was 3.8/0.3 mm Hg, and diastolic BP was 3.5/0.6 mm Hg. In addition, taurine supplementation significantly improved endothelium-dependent and endothelium-independent vasodilation and increased plasma H2S and taurine concentrations. Furthermore, changes in BP were negatively correlated with both the plasma H2S and taurine levels in taurine-treated prehypertensive individuals. To further elucidate the hypotensive mechanism, experimental studies were performed both in vivo and in vitro. The results showed that taurine treatment upregulated the expression of hydrogen sulfide-synthesizing enzymes and reduced agonist-induced vascular reactivity through the inhibition of transient receptor potential channel subtype 3-mediated calcium influx in human and mouse mesenteric arteries. In conclusion, the antihypertensive effect of chronic taurine supplementation shows promise in the treatment of prehypertension through improvement of vascular function. © 2016 American Heart Association, Inc.

    Previous investigations have demonstrated that choline deficiency, manifested in low plasma-free choline concentration and hepatic injury, may develop in patients who require long-term total parenteral nutrition (TPN). Preliminary studies have suggested lecithin or choline supplementation might lead to improved visual memory in the elderly and reverse abnormal neuropsychological development in children. We sought to determine if choline-supplemented TPN would lead to improvement in neuropsychological test scores in a group of adult, choline-deficient outpatients receiving TPN. Eleven subjects (8 males, 3 females) who received nightly TPN for more than 80% of their nutritional needs for at least 12 weeks before entry in the study were enrolled. Exclusion criteria included active drug abuse, mental retardation, cerebral vascular accident, head trauma, hemodialysis or peritoneal dialysis, (prothrombin time [PT] >2x control), or acquired immune deficiency syndrome (AIDS). Patients were randomly assigned to receive their usual TPN regimen (n = 6, aged 34.0 +/- 12.6 years) over a 12-hour nightly infusion or their usual TPN regimen plus choline chloride (2 g) (n = 5, aged 37.3 +/- 7.3 years). The following neuropsychological tests were administered at baseline and after 24 weeks of choline supplementation (or placebo): Weschler Adult Intelligence Scale-Revised (WAIS-R, intellectual functioning), Weschler Memory Scale-Revised (WMS-R, two subtests, verbal and visual memory), Rey-Osterrieth Complex Figure Test (visuospatial functioning and perceptual organization), Controlled Oral Word Association Test (verbal fluency), Grooved Pegboard (manual dexterity and motor speed), California Verbal Learning Test (CVLT, rote verbal learning ability), and Trail Making Parts A & B (visual scanning, psychomotor speed and set shifting). Scores were reported in terms of standard scores including z scores and percentile ranks. Mean absolute changes in raw scores were compared between groups

    To investigate the question of whether supplementation with an oral oil formulation rich in natural stable fish oil can alter skin elasticity, transepidermal water loss (TEWL), and skin roughness in healthy women. Twenty-four healthy women aged 40-60 years participated in a single-blind randomized trial for testing the effect of a proprietary oral supplement for skin nutrition (Eskimo Skin Care) on skin elasticity, TEWL, and skin roughness. Skin elasticity was measured by an optical cutometer, TEWL by a water-loss module based upon the vapour gradient principle, and skin roughness with a three-dimensional microtopography imaging system. Skin elasticity increased by 10% after 3 months of treatment with the supplement, a statistically significant increase in comparison with the control group (p=0.0298). There was a trend, though not statistically significant, towards a positive influence on the skin's barrier function. No effect on the skin roughness was observed. Eskimo Skin Care, an oral preparation rich in natural stable fish oil, can improve skin elasticity.

    Oncological treatments are associated with toxicities that may decrease compliance to treatment in most genitourinary cancer patients. Supplementation with pharmaceutical-standardized supplement may be a supplementary method to control the side effects after chemo- and radiotherapy and the increased oxidative stress associated to treatments. This registry study evaluated a natural combination of supplements containing curcumin, cordyceps, and astaxanthin (Oncotris™) used as supplementary management in genitourinary cancer patients who had undergone oncological therapy. Patients with genitourinary cancers (prostate or bladder malignancies) who had undergone and completed cancer treatments (radiotherapy, chemotherapy or intravesical immunotherapy with increased oxidative stress and residual symptoms) were recruited in this registry, supplement study. Registry subjects (n = 61) freely decided to follow either a standard management (SM) (control group = 35) or SM plus oral daily supplementation (supplement group = 26). Evaluation of severity of treatment-related residual side effects, blood count test, prostate-specific antigen (PSA) test and plasma free radicals (oxidative stress) were performed at inclusion and at the end of the observational period (6 weeks). Two patients dropped out during the registry. Therefore, the analysis included 59 participants: 26 individuals in the supplementation group and 33 in the control group. In the supplement group, the intensity of signs and symptoms (treatment-related) and residual side effects significantly decreased at 6 weeks: minimal changes were observed in controls. Supplementation with Oncotris™ was associated with a significant improvement in blood cell count and with a decreased level of plasmatic PSA and oxidative stress. Naturally-derived supplements, specifically Oncotris™ (patent pending), could support the body to overcome the treatment-related toxicities - and the relative oxidative stress in cancer patients.

Various effective programmes have been laid down for its management, mainly daily supplementation of iron folic acid (IFA tablets. Following the same, standard obstetrical practice has included the IFA supplementation without requiring the determination of iron deficiency. In this study, a total of 120 primigravida (N = 60; non-anaemic (Hb > 11 g/dl and N = 60 anaemic (Hb = 8–11 g/dl were selected among those attending the Antenatal Clinic in Department of Obstetrics and Gynaecology, All India Institute of Medical Sciences, Ansari Nagar, New Delhi, India. They were supplemented with daily and weekly IFA tablets till 6 weeks postpartum. Corresponding changes in haemoglobin level on advance of pregnancy, side effects and compliance associated with daily and weekly IFA supplementation and its associations with iron status markers were studied. The inflammatory markers were also estimated. The statistical significance level (p < 0.05 between the groups were assessed by applying unpaired t-test using SPSS (version 16.0. The obtained results publicized the salutary role of daily IFA supplementation in improving the haemoglobin level and iron status markers in anaemic pregnant women though the levels could not reach up to the non-anaemic haemoglobin levels. However, weekly IFA supplementation seems to be a better approach in non-anaemic pregnant women where almost comparable results were obtained in terms of haematological parameters, gestation length and birth weight. Conclusion: Weekly IFA supplementation found to be as effective as daily supplementation in iron sufficient non-anaemic pregnant women whereas anaemic pregnant women should be prescribed daily IFA supplementation irrespective of iron replete/deplete state.

    Full Text Available Abstract Background This study focuses on Swedish nursing students' motivation toward their studies during their three year academic studies. Earlier studies show the importance of motivation for study commitment and result. The aim was to analyze nursing students' estimation of their degree of motivation during different semester during their education and to identify reasons for the degree of motivation. Methods A questionnaire asking for scoring motivation and what influenced the degree of motivation was distributed to students enrolled in a nursing programme. 315 students who studied at different semesters participated. Analyzes were made by statistical calculation and content analysis. Results The mean motivation score over all semesters was 6.3 (ranked between 0–10 and differed significantly during the semesters with a tendency to lower score during the 5th semester. Students (73/315 with motivation score 6 reported positive opinions to becoming a nurse (125/234, organization of the programme and attitude to the studies. The mean score value for the motivation ranking differed significantly between male (5.8 and female (6.8 students. Conclusion Conclusions to be drawn are that nursing students mainly grade their motivation positive distributed different throughout their entire education. The main motivation factor was becoming a nurse. This study result highlights the need of understanding the students' situation and their need of tutorial support.

    Full Text Available Diet-induced thermogenesis (DIT is believed to be largely related to ATP production, which is dependent on phosphorus (P availability. We aimed to test the effect of P addition on DIT of lean and overweight/obese healthy subjects. DIT was measured with or without P in 10 lean and 13 overweight/obese adults in a double-blind randomized cross-over pilot study with one week washout period. After 10 h overnight fast, resting metabolic rate, respiratory quotient, and substrate utilization were measured at fasting and every 30 min for 3 h after subjects drank a standardized glucose solution, with P (500 mg or placebo pills. Subjective ratings of hunger and satiety were assessed before and after the end of each experiment using validated visual analogue scale (VAS questionnaires. Overweight/obese subjects had a blunted DIT with placebo, while P supplementation induced a 23% increase in their DIT area under the curve (p < 0.05, which was associated with a significant increase in carbohydrate oxidation. Subjects had lower appetite following P supplementation, which was expressed as a significantly (p = 0.02 lower desire to eat a meal (4.0 ± 0.7 cm compared with placebo (5.8 ± 0.9 cm. P supplementation recovers the blunted diet-induced thermogenesis in overweight and obese subjects and enhances their postprandial satiety.

    An experimental study was conducted on eight litters of newborn rats to evaluate the effects of supplemental oxygen administration on the retinal vasculature. The animals and their mothers were kept inside a pressure chamber and treated for the first 5 days of life. On the sixth day, they were removed and kept for five more days under room air and normobaric conditions. Three litters received continuous flow oxygen at 80% at a compression pressure of +81 kPa, one litter oxygen at 80% at a pressure of -39.5 kPa atms and three other litters received oxygen at 80% under normobaric conditions. The eighth litter was treated with room air oxygen at a compression pressure of +81 kPa. A severe retinopathy with marked retinal neovascularization was seen only in the newborn animals of the litters that received oxygen supplementation under normobaric or hypobaric conditions. Retinal vessels showed no pathological changes in the litters treated with hyperbaric normoxia or hyperoxia. It is possible to hypothesize that the prolonged period of oxygen supplementation failed to produce harmful effects on the retinal vasculature because the moderate hyperbarism caused mild retinal and choroidal vasoconstriction thus preventing excessive oxygen transport to the inner retina from the choroid during hyperoxia without inducing structural damage to the retinal tissue.

    Adjuvants or alternatives to antibiotics in urinary tract infections (UTIs) during pregnancy seem advisable because of possible fetal stress. The present study assessed the effectiveness of a food supplement containing L-methionine and Hibiscus sabdariffa L. and Boswellia serrata Roxb. extracts as a treatment for symptomatic UTIs in pregnancy. Pregnant patients with symptomatic cystitis were screened for UTIs in three different clinical centers. Those unwilling to take antibiotics were offered two alternative treatments: (A) a 1-week treatment with the food supplement or (B) a week in which they were advised to increase their fluid consumption to more than 1.5 L daily. After 1 week, group B patients who still had positive urine cultures (UCs) or had no UC performed took the food supplement for an additional week. UCs were performed on all patients at the first visit (w0) and on most of them at 7 days (w1). Patients who were still positive at w1 or had no UC performed at w1 had UC performed 14 days (w2) thereafter. Of 264 pregnant women enrolled, 216 joined group A, while 48 joined group B. At w1, 70.0% of group A patients and 43.2% of those in group B had negative UCs (p = 0.003). The reduction of bacterial load was 42.2% ± 8.0% and 4.5% ± 9.2%, respectively (p UTI in pregnancy.

    Full Text Available Metabolic syndrome is associated with disturbances in gut microbiota composition. We aimed to investigate the effect of Lactobacillus casei Shirota (LcS on gut microbiota composition, gut barrier integrity, intestinal inflammation and serum bile acid profile in metabolic syndrome. In a single-centre, prospective, randomised controlled pilot study, 28 subjects with metabolic syndrome received either LcS for 12 weeks (n = 13 or no LcS (n = 15. Data were compared to healthy controls (n = 16. Gut microbiota composition was characterised from stool using 454 pyrosequencing of 16S rRNA genes. Serum bile acids were quantified by tandem mass spectrometry. Zonulin and calprotectin were measured in serum and stool by ELISA. Bacteroidetes/Firmicutes ratio was significantly higher in healthy controls compared to metabolic syndrome but was not influenced by LcS. LcS supplementation led to enrichment of Parabacteroides. Zonulin and calprotectin were increased in metabolic syndrome stool samples but not influenced by LcS supplementation. Serum bile acids were similar to controls and not influenced by LcS supplementation. Metabolic syndrome is associated with a higher Bacteroidetes/Firmicutes ratio and gut barrier dysfunction but LcS was not able to change this. LcS administration was associated with subtle microbiota changes at genus level.ClinicalTrials.gov NCT01182844.

    Introduction Access to quality healthcare services is considered a moral right. However, for people living in regional locations, timely access to the services that they need may not always be possible because of structural and attitudinal barriers. This suggests that people living in regional areas may have unmet healthcare needs. The aim of this research will be to examine the healthcare needs, expectations and experiences of regional South Australians. Methods and analysis The Regional South Australia Health (RESONATE) survey is a cross-sectional study of adult health consumers living in any private or non-private dwelling, in any regional, rural, remote or very remote area of South Australia and with an understanding of written English. Data will be collected using a 45-item, multidimensional, self-administered instrument, designed to measure healthcare need, barriers to healthcare access and health service utilisation, attitudes, experiences and satisfaction. The instrument has demonstrated acceptable psychometric properties, including good content validity and internal reliability, good test–retest reliability and a high level of acceptability. The survey will be administered online and in hard-copy, with at least 1832 survey participants to be recruited over a 12-month period, using a comprehensive, multimodal recruitment campaign. Ethics and dissemination The study has been reviewed and approved by the Human Research Ethics Committee of the University of South Australia. The results will be actively disseminated through peer-reviewed journals, conference presentations, social media, broadcast media, print media, the internet and various community/stakeholder engagement activities.

    To reassess cochleostomy techniques among North American cochlear implant surgeons after a 6-year period of widespread education and research on the topic. Prospective cohort study. A multiple-choice survey of cochlear implant techniques was distributed to surgeons attending the William House Cochlear Implant Study Group in 2006 and 2012. This survey contained questions regarding routine surgical access and cochleostomy techniques. Responses were anonymous, and >50% were repeat respondents. Statistical analysis sought changes in technique in the past 6 years. Comparisons between 2006 and 2012 responses revealed no significant changes in the proportion of surgeons identifying the facial nerve or chorda tympani. By contrast, respondents in 2012 were more likely to drill off the round window niche overhang (P < .001), use a round window insertion (P < .001), or make a smaller cochleostomy (P = .003). In two images of a transfacial recess approach, there was a significant increase in the proportion choosing an inferior or anterior cochleostomy site over a superior location (image 1, 76% in 2006 to 92% in 2012, P = .003; image 3, 78% to 90%, respectively, P = .044). This repeat survey documents a change in practice among cochlear implant surgeons. Specifically, scala tympani access techniques now appear to be more consistent with known anatomical relationships in the round window region. These findings may have resulted from the concerted education and research efforts over the past 6 years. © 2014 The American Laryngological, Rhinological and Otological Society, Inc.

    Full Text Available Landslide is one of prominent geohazards that frequently affects Indonesia, especially in the rainy season. It destroys not only environment and property, but usually also causes deaths. Landslide monitoring is therefore very crucial and should be continuously done. One of the methods that can have a contribution in studying landslide phenomena is repeated GPS survey method. This paper presents and discusses the operational performances, constraints and results of GPS surveys conducted in a well known landslide prone area in West Java (Indonesia, namely Megamendung, the hilly region close to Bogor. Three GPS surveys involving 8 GPS points have been conducted, namely on April 2002, May 2003 and May 2004, respectively. The estimated landslide displacements in the area are relatively quite large in the level of a few dm to a few m. Displacements up to about 2-3 m were detected in the April 2002 to May 2003 period, and up to about 3-4 dm in the May 2003 to May 2004 period. In both periods, landslides in general show the northwest direction of displacements. Displacements vary both spatially and temporally. This study also suggested that in order to conclude the existence of real and significant displacements of GPS points, the GPS estimated displacements should be subjected to three types of testing namely: the congruency test on spatial displacements, testing on the agreement between the horizontal distance changes with the predicted direction of landslide displacement, and testing on the consistency of displacement directions on two consecutive periods.

    This report proposes a synthesis of a study based on a survey on energy consumption and expenditures directly paid by local communities, the built patrimony, public lighting and vehicle fuel, the electricity consumptions and expenditures of drinking water stations, sewage treatment plants and waste treatment plants. The survey has been performed among more than 1600 towns and communities of more than 500 inhabitants in metropolitan France and overseas territories. The considered built patrimony comprises schools, swimming pools, other sport facilities, administrative buildings, social and cultural facilities, and other various facilities. The report indicates key figures for 2012 in terms of global assessment, main consumer sectors, buildings, public lighting, vehicle fuel, actions for energy management, and renewable energies. The evolution of consumptions and expenditures is then analysed (evolution of main indicators, market shares of energies in buildings)

    Nutrition is one of the fundamentals of care provided to critically ill adults. The volume of enteral nutrition received, however, is often much less than prescribed due to multiple functional and process issues. To deliver the prescribed volume and correct the energy deficit associated with enteral nutrition alone, parenteral nutrition can be used in combination (termed "supplemental parenteral nutrition"), but benefits of this method have not been firmly established. A multi-centre, randomised, clinical trial is currently underway to determine if prescribed energy requirements can be provided to critically ill patients by using a supplemental parenteral nutrition strategy in the critically ill. This prospective, multi-centre, randomised, stratified, parallel-group, controlled, phase II trial aims to determine whether a supplemental parenteral nutrition strategy will reliably and safely increase energy intake when compared to usual care. The study will be conducted for 100 critically ill adults with at least one organ system failure and evidence of insufficient enteral intake from six intensive care units in Australia and New Zealand. Enrolled patients will be allocated to either a supplemental parenteral nutrition strategy for 7 days post randomisation or to usual care with enteral nutrition. The primary outcome will be the average energy amount delivered from nutrition therapy over the first 7 days of the study period. Secondary outcomes include protein delivery for 7 days post randomisation; total energy and protein delivery, antibiotic use and organ failure rates (up to 28 days); duration of ventilation, length of intensive care unit and hospital stay. At both intensive care unit and hospital discharge strength and health-related quality of life assessments will be undertaken. Study participants will be followed up for health-related quality of life, resource utilisation and survival at 90 and 180 days post randomisation (unless death occurs first). This trial

    Purpose Urothelial Carcinoma (UC) has the highest lifetime treatment cost of any cancer making it an ideal target for preventative therapies. Previous work has suggested that certain vitamin and mineral supplements may reduce the risk of UC. We sought to use the prospective VITamins And Lifestyle (VITAL) cohort to examine the association of all commonly taken vitamin and mineral supplements as well as 6 common anti-inflammatory supplements with incident UC in a United States population. Materials&Methods 77,050 eligible VITAL participants completed a detailed questionnaire at baseline on supplement use and cancer risk factors. . After 6 years of follow-up, 330 incident UC cases occurring in the cohort were identified via linkage to the Seattle-Puget Sound Surveillance, Epidemiology and End Results (SEER) cancer registry. We analyzed use of supplemental vitamins (multivitamins, beta-carotene, retinol, folic acid, vitamins B1, B3, B6, B12, C, D and E), minerals (calcium, iron, magnesium, zinc, and selenium), and anti-inflammatory supplements (glucosamine, chondroitin, saw-palmetto, ginko-biloba, fish oil and garlic). For each supplement, the hazard ratios (risk ratios) for UC comparing each category of users to nonusers, and 95% confidence intervals, were determined using Cox proportional hazards regression., adjusted for potential confounders. Results None of the vitamin, mineral or anti-inflammatory supplements was significantly associated with UC risk in either age-adjusted or multivariate models. Conclusions The results of this study do not support the use of commonly taken vitamin or mineral supplements or 6 common anti-inflammatory supplements for chemoprevention of UC. PMID:21334017

    The 2015 National Mental Health Survey (NMHS) is the fourth mental survey conducted in Colombia, and is part of the National System of Surveys and Population Studies for health. A narrative description is used to explain the background, references, the preparation, and characteristics of the 2015 NMHS. The 2015 NMHS and its protocol emerge from the requirements that support the national and international policies related to mental health. Together with the Ministry of Health and Social Protection, the objectives, the collection tools, the sample, and the operational plan are defined. The main objective was to obtain updated information about the mental health, mental problems and disorders, accessibility to health services, and an evaluation of health conditions. Participants were inhabitants from both urban and rural areas, over 7 years old, and in whom the comprehension of social determinants and equity were privileged. An observational cross-sectional design with national, regional and age group representativity, was used. The age groups selected were 7-11, 12-17, and over 18 years old. The regions considered were Central, Orient, Atlantic, Pacific, and Bogota. The calculated sample had a minimum of 12,080 and a maximum of 14,496 participants. A brief summary of the protocol of the 2015 NMHS is presented. The full document with all the collection tools can be consulted on the Health Ministry webpage. Copyright © 2016.

    Full Text Available Abstract Background Athletes are expected to consider multiple factors when making informed decision about nutritional supplement use. Besides rules, regulations and potential health hazards, the efficacy of different nutritional supplements in performance enhancement is a key issue. The aim of this paper was to find evidence for informed decision making by investigating the relationship between specific performance-related reasons for supplement use and the reported use of nutritional supplements. Methods The 'UK Sport 2005 Drug Free Survey' data (n = 874 were re-analysed using association [χ2] and 'strength of association' tests [ϕ] to show the proportion of informed choices and to unveil incongruencies between self-reported supplement use and the underlying motives. Results Participants (n = 520 reported supplement use in the pattern of: vitamin C (70.4%, creatine (36.1%, whey protein (30.6%, iron (29.8%, caffeine (23.8%, and ginseng (8.3% for the following reasons: strength maintenance (38.1%, doctors' advice (24.2%, enhancing endurance (20.0%, ability to train longer (13.3%, and provided by the governing body (3.8%. Of thirty possible associations between the above supplements and reasons, 11 were predictable from literature precedents and only 8 were evidenced and these were not strong (ϕ 2 = 49.14, p 2 = 97.08, p 2 = 97.82, p Conclusion This study provided a platform for assessing congruence between athletes' reasons for supplement use and their actual use. These results suggest that a lack of understanding exists in supplement use. There is an urgent need to provide accurate information which will help athletes make informed choices about the use of supplements.

    Systematic reviews of randomised controlled trials report that probiotics reduce the risk of necrotising enterocolitis (NEC) in preterm neonates. To determine whether routine probiotic supplementation (RPS) to preterm neonates would reduce the incidence of NEC. The incidence of NEC ≥ Stage II and all-cause mortality was compared for an equal period of 24 months 'before' (Epoch 1) and 'after' (Epoch 2) RPS with Bifidobacterium breve M-16V in neonates Bifidobacterium breve M-16V was associated with decreased NEC≥ Stage II and 'NEC≥ Stage II or all-cause mortality' in neonates <34 weeks. Large sample size is required to assess the potential benefits of RPS in neonates <28 weeks.

    Full Text Available Micronutrient fortified flour (MFF, supplementary food rations and micronutrient (MN supplements may prevent deficiencies among pregnant women. Objectives of cross-sectional surveys in 2004 (n = 533 and 2006 (n = 515 were to assess the impact of new food rations (flour, oil and supplements on MN status by trimester of pregnancy in the Maela refugee camp. Hemoglobin, iron status, zinc, retinol, β-carotene and tryptophan decreased, while α-/γ-tocopherol and 5-methyltetrahydrofolate (5-MTHF increased from first to third trimester. In 2006, mean zinc and α-tocopherol for each trimester was significantly higher than in 2004. The weeks of supplemented thiamine and folic acid were positively correlated with thiamine diphosphate (TDP and 5-MTHF, but not for ferrous sulfate as iron deficiency was observed in 38.5% of third-trimester women. Frequent consumption of fish paste and owning a garden or animal were associated with significantly higher iron status, retinol, β-carotene, and 5-MTHF. In conclusion, MFF and supplementary oil were most likely to explain improved zinc and α-tocopherol status, while thiamine and folate supplements ensured high TDP and 5-MTHF in late pregnancy. MN supplements, MN-rich staple food, small gardens, and programs to improve iron compliance are promising strategies to prevent MN deficiencies during pregnancy in vulnerable populations.

    Full Text Available Abstract Background An earlier case-control study from Western Australia reported a protective effect of maternal folic acid supplementation during pregnancy on the risk of childhood acute lymphoblastic leukaemia (ALL. The present study tested that association. Methods A national case-control study was conducted in New Zealand. The mothers of 97 children with ALL and of 303 controls were asked about vitamin and mineral supplements taken during pregnancy. Results There was no association between reported folate intake during pregnancy and childhood ALL (adjusted odds ratio (OR 1.1, 95% confidence interval (CI 0.5–2.7. Combining our results with the study from Western Australia and another study from Québec in a meta-analysis gave a summary OR of 0.9 (95% CI 0.8–1.1. Conclusion Our own study, of similar size to the Australian study, does not support the hypothesis of a protective effect of folate on childhood ALL. Neither do the findings of the meta-analysis.

  15. Investigation of background acoustical effect on online surveys: A case study of a farmers' market customer survey

    Science.gov (United States)

    Tang, Xingdi

    Since the middle of 1990s, internet has become a new platform for surveys. Previous studies have discussed the visual design features of internet surveys. However, the application of acoustics as a design characteristic of online surveys has been rarely investigated. The present study aimed to fill that research gap. The purpose of the study was to assess the impact of background sound on respondents' engagement and satisfaction with online surveys. Two forms of background sound were evaluated; audio recorded in studios and audio edited with convolution reverb technique. The author recruited 80 undergraduate students for the experiment. These students were assigned to one of three groups. Each of the three groups was asked to evaluate their engagement and satisfaction with a specific online survey. The content of the online survey was the same. However, the three groups was exposed to the online survey with no background sound, with background sound recorded in studios; and with background sound edited with convolution reverb technique. The results showed no significant difference in engagement and satisfaction in the three groups of online surveys; without background sound, background sound recorded in studios, and background sound edited with convolution reverb technique. The author suggests that background sound does not contribute to online surveys in all the contexts. The industry practitioners should be careful to evaluate the survey context to decide whether the background sound should be added. Particularly, ear-piercing noise or acoustics which may link to respondents' unpleasant experience should be avoided. Moreover, although the results did not support the advantage of the revolution reverb technique in improving respondents' engagement and satisfaction, the author suggests that the potential of the revolution reverb technique in the applications of online surveys can't be totally denied, since it may be useful for some contexts which need further

    Full Text Available Severe fatigue can negatively affect quality of life, and oxidative stress may play a role in its mechanism. The aim of this study was to evaluate the effect of dietary supplementation of astaxanthin and sesamin (AS, strong food-derived antioxidants, on fatigue. Twenty-four healthy volunteers were supplemented with AS and placebo, each for four weeks. After each supplementation period, participants underwent tasks inducing mental and physical fatigue (visual display terminal task and ergometer task, respectively. Subjective fatigue was evaluated using a visual analogue scale during and after the mental and physical tasks, and daily subjective fatigue was evaluated by the Chalder fatigue questionnaire. Secondary outcomes included other subjective feelings, work efficiency, autonomic nerve activity, levels of an oxidative stress marker (plasma phosphatidylcholine hydroperoxide (PCOOH and safety. AS supplementation was associated with significantly improved recovery from mental fatigue compared with placebo. Increased PCOOH levels during mental and physical tasks were attenuated by AS supplementation. No differences between AS and placebo were detected in secondary outcomes, and no adverse effects of AS supplementation were observed. In conclusion, AS supplementation may be a candidate to promote recovery from mental fatigue which is experienced by many healthy people.

    To describe a novel observational study that supplemented primary care electronic health record (EHR) data with sample collection and patient diaries. The study was set in primary care in England. A list of 3974 potentially eligible patients was compiled using data from the Clinical Practice Research Datalink. Interested general practices opted into the study then confirmed patient suitability and sent out postal invitations. Participants completed a drug-use diary and provided saliva samples to the research team to combine with EHR data. Of 252 practices contacted to participate, 66 (26%) mailed invitations to patients. Of the 3974 potentially eligible patients, 859 (22%) were at participating practices, and 526 (13%) were sent invitations. Of those invited, 117 (22%) consented to participate of whom 86 (74%) completed the study. We have confirmed the feasibility of supplementing EHR with data collected directly from patients. Although the present study successfully collected essential data from patients, it also underlined the requirement for improved engagement with both patients and general practitioners to support similar studies. © 2017 The Authors.

    Full Text Available There is a growing use of dietary supplements in many countries including China. This study aimed to document the prevalence of dietary supplements use and characteristics of Chinese pre-school children using dietary supplements in Australia and China. A survey was carried out in Perth, Western Australia of 237 mothers with children under five years old and 2079 in Chengdu and Wuhan, China. A total of 22.6% and 32.4% of the Chinese children were taking dietary supplements in Australia and China, respectively. In China, the most commonly used dietary supplements were calcium (58.5% and zinc (40.4%, while in Australia, the most frequently used types were multi-vitamins/minerals (46.2% and fish oil (42.3%. In Australia, “not working”, “never breastfeed”, “higher education level of the mother” and “older age of the child” were associated with dietary supplement use in children. In China, being unwell and “having higher household income” were significantly related to dietary supplement usage. Because of the unknown effects of many supplements on growth and development and the potential for adverse drug interactions, parents should exercise caution when giving their infants or young children dietary supplements. Wherever possible it is preferable to achieve nutrient intakes from a varied diet rather than from supplements.

    Full Text Available Recent research has suggested a possible link between Parkinson's disease (PD and Fabry disease. To test this relationship, we administered a self-report and family history questionnaire to determine the prevalence of PD in Fabry disease patients and family members with likely pathogenic alpha-galactosidase A (GLA mutations. A total of 90 Fabry patients (77 from the online survey and 13 from the Icahn School of Medicine at Mount Sinai (ISMMS were included in the analysis. Two of the Fabry disease patients who completed the online survey were diagnosed with PD (2/90, 2.2%. Among probands older than 60, 8.3% (2/24 were diagnosed with PD. Using Kaplan Meier survival analysis, the age-specific risk of PD by age 70 was 11.1%. Family history was available on 72 Fabry families from the online study and 9 Fabry families from ISMMS. Among these 81 families, 6 (7.4% had one first degree relative who fit the criteria for a conservative diagnosis of PD. The results of this study suggest that there may be an increased risk of developing PD in individuals with GLA mutations, but these findings should be interpreted with caution given the limitations of the study design.

    Full Text Available Background: Whether Vitamin D supplementation in prediabetes subjects prevents the development of diabetes is a matter of debate, and the results are inconsistent. This open-label, randomized study in subjects with prediabetes evaluated the effect of 12 months of Vitamin D supplementation on glycemic parameters and progression of prediabetes to diabetes in an ethnically homogeneous Kashmiri population. Materials and Methods: A total of 147 subjects were diagnosed as prediabetes out of which 137 subjects were randomized to receive in addition to standard lifestyle measures, either Vitamin D 60,000 IU weekly for 4 weeks and then 60,000 IU monthly (n = 69 or no Vitamin D (n = 68. Fasting plasma glucose (FPG, 2-h plasma glucose and A1C levels were estimated at 0, 6 and 12 months. Changes in FPG, 2-h plasma glucose, A1C level and the proportion of subjects developing diabetes were assessed among 129 subjects. Results: At 12 months, A1C levels were significantly lesser (5.7% ± 0.4% in the Vitamin D supplemented group when compared with non-Vitamin D supplemented (6.0% ± 0.3%. Similarly, FPG (97 ± 7 and 2-h plasma glucose (132 ± 16 were significantly less in Vitamin D supplemented group as compared with non-Vitamin D supplemented group (FPG = 116 ± 6 and 2-h plasma glucose = 157 ± 25 at 12 months. Nine out of 65 in non-Vitamin D supplemented and seven out of 64 in the Vitamin D supplemented group developed diabetes. Conclusions: Vitamin D supplementation in prediabetes subjects significantly lowered FPG, 2-h plasma glucose and A1C levels.

    Objective Describe the content and frequency of provider-patient dietary supplement discussions during primary care office visits. Methods Inductive content analysis of 1477 transcribed audio-recorded office visits to 102 primary care providers was combined with patient and provider surveys. Encounters were collected in Los Angeles, California (2009–2010), geographically-diverse practice settings across the United States (2004–2005), and Sacramento, CA (1998–1999). Results Providers discussed 738 dietary supplements during encounters with 357 patients (24.2% of all encounters in the data). They mentioned: 1) reason for taking the supplement for 46.5% of dietary supplements; 2) how to take the supplement for 28.2%; 3) potential risks for 17.3%; 4) supplement effectiveness for 16.7%; and 5) supplement cost or affordability for 4.2%. Of these five topics, a mean of 1.13 (SD=1.2) topics were discussed for each supplement. More topics were reviewed for non-vitamin non-mineral supplements (mean 1.47 (SD=1.2)) than for vitamin/mineral supplements (mean 0.99 (SD=1.1); psupplements are occurring, it is clear that more discussion might be needed to inform patient decisions about supplement use. Practice Implication Physicians could more frequently address topics that may influence patient dietary supplement use, such as the risks, effectiveness, and costs of supplements. PMID:23466249

    Large investments are currently made in community-based complementary food supplement (Ying Yang Bao, YYB) programs to improve nutrition of young children in rural areas in China. However, there is a lack of knowledge about the experience and challenges of implementing YYB programs in China. We aimed to: 1) monitor distribution of YYB; 2) assess children's adherence to and acceptability of YYB; and 3) evaluate community-based strategies to improve the program. This mixed methods evaluation study combined data from surveys and focus groups that took place during a controlled interventional evaluation trial. The trial aimed to evaluate the effectiveness of community-based YYB distribution on improving children's health status in rural areas in China. We conducted five cross-sectional surveys with caregivers of children aged 6-23 months (baseline survey (N = 1804) in August 2012 and four follow-up cross-sectional surveys: 1) N = 494 in January 2013; 2) N = 2187 in August 2013; 3) N = 504 in January 2014; and 4) N = 2186 in August 2014) in one rural county in Qinghai Province. We used a two-stage cluster sampling technique to select mothers with eligible children for each survey. Information was collected from caregivers on household characteristics, YYB consumption and acceptability in the surveys. High adherence in each survey was defined as children who consumed at least four YYB sachets during the previous week. A logistic regression model was developed to obtain odds ratios (OR) with 95% confidence intervals of factors associated with high adherence. Also, we conducted 10 focus groups with73 caregivers and health workers involved in the YYB distribution. Content analysis was used to explore qualitative findings, which were used to gain deeper insight into the quantitative results. Around 90% of caregivers had ever received YYB and more than 80% of children ever took YYB. Caregivers mainly knew about YYB through their village doctors. High

    Full Text Available Most scholars argue that cross-national research is indispensable for establishing the generalizability of theories and the validity of interpretations derived from single-nation studies. Another important aspect of comparative studies is that they force us to test our interpretations against cross-cultural diferences and inconsistencies. In journalism studies, the advantages of cross-national research are obvious. While the empirical inquiry into news-making has generated a vast quantity of data, some of the more fundamental questions in journalism research remain largely unresolved: What shapes the news and the structures of journalism most? Is it politics, economy, or culture? How do the conventional Western values of objective journalism ft in with non-Western cultures? In this article, I would like to propose the creation of a “World Journalism Survey”, modeled after the World Values Survey, for a better map of the cultural diferences in journalism practices around the world.

    Maternal prenatal supplementation with folic acid and other vitamins has been inconsistently associated with a reduced risk of childhood acute lymphoblastic leukemia (ALL). Little is known regarding the association with acute myeloid leukemia (AML), a rarer subtype. We obtained original data on prenatal use of folic acid and vitamins from 12 case-control studies participating in the Childhood Leukemia International Consortium (enrollment period: 1980-2012), including 6,963 cases of ALL, 585 cases of AML, and 11,635 controls. Logistic regression was used to estimate pooled odds ratios (ORs) and 95% confidence intervals (CIs), adjusted for child's age, sex, ethnicity, parental education, and study center. Maternal supplements taken any time before conception or during pregnancy were associated with a reduced risk of childhood ALL; odds ratios were 0.85 (95% CI = 0.78-0.92) for vitamin use and 0.80 (0.71-0.89) for folic acid use. The reduced risk was more pronounced in children whose parents' education was below the highest category. The analyses for AML led to somewhat unstable estimates; ORs were 0.92 (0.75-1.14) and 0.68 (0.48-0.96) for prenatal vitamins and folic acid, respectively. There was no strong evidence that risks of either types of leukemia varied by period of supplementation (preconception, pregnancy, or trimester). Our results, based on the largest number of childhood leukemia cases to date, suggest that maternal prenatal use of vitamins and folic acid reduces the risk of both ALL and AML and that the observed association with ALL varied by parental education, a surrogate for lifestyle and sociodemographic characteristics.

  6. Econometric studies of urban population density: a survey.

    Mcdonald, J F

    1989-01-01

    This paper presents the 1st reasonably comprehensive survey of empirical research of urban population densities since the publication of the book by Edmonston in 1975. The survey summarizes contributions to empirical knowledge that have been made since 1975 and points toward possible areas for additional research. The paper also provides a brief interpretative intellectual history of the topic. It begins with a personal overview of research in the field. The next section discusses econometric issues that arise in the estimation of population density functions in which density is a function only of a distance to the central business district of the urban area. Section 4 summarizes the studies of a single urban area that went beyond the estimation of simple distance-density functions, and Section 5 discusses studies that sought to explain the variations across urban areas in population density patterns. McDonald refers to the standard theory of urban population density throughout the paper. This basic model is presented in the textbook by Mills and Hamilton and it is assumed that the reader is familiar with the model.

    Full text: Good nutrition in the first 1000 days provides a stable long term foundation for society, as it ensures a child's growth to his/her potential (1). Pregnant women who suffer from multiple micronutrient deficiencies have been associated with poor pregnancy outcomes including Low Birth weight-LBW (4). Iron deficiency anemia is linked to an increased risk of infections (4), and is still a health problem in the kingdom of Bahrain with the prevalence of 22.7% to 54% (5). The World Health Organization (WHO), United Nation Children's fund (UNICEF) and American Academy of Pediatrics recommendations are to initiate breastfeeding within the first hour of life and to and sustain exclusive breastfeeding for 6 months (6). Several studies have shown a downward trend of breastfeeding in developing countries such as Kingdom of Saudi Arabia (7,8). Studies in Kingdom of Saudi Arabia and Kingdom of Bahrain have shown partial breastfeeding at early months<6month age (8,9) Aim: To provide a preliminary evaluation of the mother's attitude/practices toward antenatal care, micronutrient supplementation and breastfeeding in Salmaniya Medical Complex (SMC), Kingdom of Bahrain. Methods: A sample of 62 Bahraini mothers - inpatients and outpatients- within the age group of 20 years to 35 years old at SMC were asked by dietitians and diet technicians to answer 7 closed ended questions about importance of antenatal care, compliance to nutritional recommendations during pregnancy and breastfeeding practices. Statistical Package for Social Science (SPSS) was used in analyzing data collected. Fisher Exact test and Chi-Square test were used to correlate the determinants (age and education level) with mother's attitude/practices. Statistical significance was assumed at p<0.05 Results: Scores showed no significant correlation between education level mother's attitude/practices toward antenatal care, micronutrient supplementation and breastfeeding. As for age, we found more mothers above 25

    South Dakota is home to 6,000 Hutterites, the largest population of Hutterites in the United States. Observation of frequent supplement use by this population prompted the current survey based study. Use of supplements is on the rise with around 53 percent of Americans reporting at least one herbal and dietary supplement (HDS). Use and perception of HDS has not previously been evaluated in the Hutterite population. Participants were 18 years of age and older and had to be present at the time of survey administration. Surveys were administered before and after an educational presentation at five colonies to volunteer participants. Survey data was analyzed using descriptive analysis and chi-square tests. One-hundred and six surveys were completed with 81.1 percent being female. Approximately 78 percent reported using at least one type of HDS, with an average of 2.7 (SD = 1.4) supplements per person. Women were more likely to report supplement use than men. Hutterites reported they felt HDS were safer than prescription medications. Education was effective on some aspects such as telling their doctor if they are taking HDS. Some study limitations included small sample size, possible lack of survey understanding, and the limited number of male participants. The frequency of HDS use in South Dakota Hutterites appears to be very high. Baseline knowledge on the safety and regulation of HDS reveals that education of this population is needed. Further investigation of HDS use in Hutterites is warranted.

    The VST Optical Imaging of the CDFS and ES1 Fields (VOICE) Survey is a Guaranteed Time program carried out with the ESO/VST telescope to provide deep optical imaging over two 4 deg2 patches of the sky centred on the CDFS and ES1 pointings. We present the cosmic shear measurement over the 4 deg2 covering the CDFS region in the r-band using LensFit. Each of the four tiles of 1 deg2 has more than one hundred exposures, of which more than 50 exposures passed a series of image quality selection criteria for weak lensing study. The 5σ limiting magnitude in r- band is 26.1 for point sources, which is ≳1 mag deeper than other weak lensing survey in the literature (e.g. the Kilo Degree Survey, KiDS, at VST). The photometric redshifts are estimated using the VOICE u, g, r, i together with near-infrared VIDEO data Y, J, H, Ks. The mean redshift of the shear catalogue is 0.87, considering the shear weight. The effective galaxy number density is 16.35 gal/arcmin2, which is nearly twice the one of KiDS. The performance of LensFit on such a deep dataset was calibrated using VOICE-like mock image simulations. Furthermore, we have analyzed the reliability of the shear catalogue by calculating the star-galaxy cross-correlations, the tomographic shear correlations of two redshift bins and the contaminations of the blended galaxies. As a further sanity check, we have constrained cosmological parameters by exploring the parameter space with Population Monte Carlo sampling. For a flat ΛCDM model we have obtained Σ _8 = σ _8(Ω _m/0.3)^{0.5} = 0.68^{+0.11}_{-0.15}.

    Perinatal choline supplementation has produced several benefits in rodent models, from improved learning and memory to protection from the behavioral effects of fetal alcohol exposure. We have shown that supplemented choline through gestation and lactation produces long-term improvement in deficient sensory inhibition in DBA/2 mice which models a similar deficit in schizophrenia patients. The present study extends that research by feeding normal or supplemented choline diets to DBA/2 mice carrying the null mutation for the α7 nicotinic receptor gene (Chrna7). DBA/2 mice heterozygotic for Chrna7 were bred together. Dams were placed on supplemented (5 gm/kg diet) or normal (1.1 gm/kg diet) choline at mating and remained on the specific diet until offspring weaning. Thereafter, offspring were fed standard rodent chow. Adult offspring were assessed for sensory inhibition. Brains were obtained to ascertain hippocampal α7 nicotinic receptor levels. Choline-supplemented mice heterozygotic or null-mutant for Chrna7 failed to show improvement in sensory inhibition. Only wildtype choline-supplemented mice showed improvement with the effect solely through a decrease in test amplitude. This supports the hypothesis that gestational-choline supplementation is acting through the α7 nicotinic receptor to improve sensory inhibition. Although there was a significant gene-dose-related change in hippocampal α7 receptor numbers, binding studies did not reveal any choline-dose-related change in binding in any hippocampal region, the interaction being driven by a significant genotype main effect (wildtype>heterozygote>null mutant). These data parallel a human study wherein the offspring of pregnant women receiving choline supplementation during gestation, showed better sensory inhibition than offspring of women on placebo.

    Lockwood Keri A

    2011-06-01

    Full Text Available Abstract Background Malnutrition is a problem for many older people recovering from a hip and other major fractures. Oral supplementation with high calorie high protein nutrients is a simple intervention that may help older people with fractures to improve their recovery in terms of rehabilitation time, length of hospital stay and mortality. This paper reports a pilot study to test the feasibility of a trial initiated in a hospital setting with an oral supplement to older people with recent fractures. Method A randomized controlled trial with 44 undernourished participants admitted to a hospital following a fracture. The intervention group (n = 23 received a high calorie high protein supplement for forty days in addition to their diet of choice. The control group (n = 21 received high protein milk during their hospital stay in addition to their diet of choice and their usual diet when discharged from hospital. Results All participants were women and their mean age was 85.3 (± 6.1 years. Twenty nine (65% participants had a hip fracture. At baseline no differences were measured between the two groups regarding their nutritional status, their cognitive ability or their abilities in activities of daily living. There were no significant differences between the intervention and control group with reference to nutritional or functional parameters at 40 day and 4 month follow-ups. Median length of stay in hospital was 18.0 days, with 12 participants being readmitted for a median of 7.0 days. Conclusion It is feasible to perform a randomised trial in a hospital and community setting to test the effect of an oral high energy high protein supplement for older people. Due to the limited number of participants and incomplete adherence with use of the supplements no conclusion can be drawn about the efficacy or effectiveness of this intervention.

    No study has concurrently measured changes in free-living whole body protein metabolism and exercise performance during recovery from an acute bout of resistance exercise. We aimed to determine if whey protein ingestion enhances whole body net protein balance and recovery of exercise performance during overnight (10 h) and 24 h recovery after whole body resistance exercise in trained men. In a double-blind crossover design, 12 trained men (76 ± 8 kg, 24 ± 4 years old, 14% ± 5% body fat; means ± standard deviation (SD)) performed resistance exercise in the evening prior to consuming either 25 g of whey protein (PRO; MuscleTech 100% Whey) or an energy-matched placebo (CHO) immediately post-exercise (0 h), and again the following morning (~10 h of recovery). A third randomized trial, completed by the same participants, involving no exercise and no supplement served as a rested control trial (Rest). Participants ingested [ 15 N]glycine to determine whole body protein kinetics and net protein balance over 10 and 24 h of recovery. Performance was assessed pre-exercise and at 0, 10, and 24 h of recovery using a battery of tests. Net protein balance tended to improve in PRO ( P = 0.064; effect size (ES) = 0.61, PRO vs. CHO) during overnight recovery. Over 24 h, net balance was enhanced in PRO ( P = 0.036) but not in CHO ( P = 0.84; ES = 0.69, PRO vs. CHO), which was mediated primarily by a reduction in protein breakdown (PRO protein supplementation improved MVC (ES = 0.76), REP (ES = 0.44), and peak power (ES = 0.55). In conclusion, whey protein supplementation enhances whole body anabolism, and may improve acute recovery of exercise performance after a strenuous bout of resistance exercise.

    Hypospadias is one of the most common urogenital congenital anomalies affecting baby boys. Prevalence estimates in Europe range from 4 to 24 per 10,000 births, depending on definition, with higher rates reported from the United States. Relatively little is known about potential risk factors, but a role for endocrine-disrupting chemicals (EDCs) has been proposed. Our goal was to elucidate the risk of hypospadias associated with occupational exposure of the mother to endocrine-disruptor chemicals, use of folate supplementation during pregnancy, and vegetarianism. We designed a case-control study of 471 hypospadias cases referred to surgeons and 490 randomly selected birth controls, born 1 January 1997-30 September 1998 in southeast England. Telephone interviews of mothers elicited information on folate supplementation during pregnancy and vegetarianism. We used a job exposure matrix to classify occupational exposure. In multiple logistic regression analysis, there were increased risks for self-reported occupational exposure to hair spray [exposed vs. nonexposed, odds ratio (OR) = 2.39; 95% confidence interval (CI), 1.40-4.17] and phthalate exposure obtained by a job exposure matrix (OR = 3.12; 95% CI, 1.04-11.46). There was a significantly reduced risk of hypospadias associated with of folate use during the first 3 months of pregnancy (OR = 0.64; 95% CI, 0.44-0.93). Vegetarianism was not associated with hypospadias risk. Excess risks of hypospadias associated with occupational exposures to phthalates and hair spray suggest that antiandrogenic EDCs may play a role in hypospadias. Folate supplementation in early pregnancy may be protective.

    Full Text Available Abstract Background Women aged ≥ 65 years are high utilizers of prescription and over-the-counter medications, and many of these women are also taking dietary supplements. Dietary supplement use by older women is a concern because of possible side effects and drug-supplement interactions. The primary aim of this study was to provide a comprehensive picture of dietary supplement use among older women in a large health plan in Northern California, USA, to raise awareness among health care providers and pharmacists about the need for implementing structural and educational interventions to minimize adverse consequences of self-directed supplement use. A secondary aim was to raise awareness about how the focus on use of herbals and megavitamins that has occurred in most surveys of complementary and alternative therapy use results in a significant underestimate of the proportion of older women who are using all types of dietary supplements for the same purposes. Methods We used data about use of different vitamin/mineral (VM supplements and nonvitamin, nonmineral (NVNM supplements, including herbals, from a 1999 general health survey mailed to a random sample of adult members of a large Northern California health plan to estimate prevalence of and characteristics associated with supplement use among women aged 65–84 (n = 3,109. Results Based on weighted data, 84% had in the past 12 months used >1 dietary supplement, 82% a VM, 59% a supplement other than just multivitamin or calcium, 32% an NVNM, and 25% an herbal. Compared to white, nonHispanic women, African-Americans and Latinas were significantly less likely to use VM and NVNM supplements and Asian/Pacific Islanders were less likely to use NVNM supplements. Higher education was strongly associated with use of an NVNM supplement. Prevalence did not differ by number of prescription medications taken. Among white, nonHispanic women, multiple logistic regression models showed that college

    In its 2001 review of the U.S. Geological Survey (USGS), the National Research Council (NRC, p. 126) cautioned that ?high-quality personnel are essential for developing high-quality science information? and urged the USGS to ?devote substantial efforts to recruiting and retaining excellent staff.? Recognizing the importance of the NRC recommendation, the USGS has committed time and resources to create a rewarding work environment with the goal of achieving the following valued outcomes: ? USGS science vitality ? Customer satisfaction with USGS products and services ? Employee perceptions of the USGS as a rewarding place to work ? Heightened employee morale and commitment ? The ability to recruit and retain employees with critical skills To determine whether this investment of time and resources was proving to be successful, the USGS Human Resources Office conducted a Rewarding Environment Culture Study to answer the following four questions. ? Question 1: Does a rewarding work environment lead to the valued outcomes (identified above) that the USGS is seeking? ? Question 2: Which management, supervisory, and leadership behaviors contribute most to creating a rewarding work environment and to achieving the valued outcomes that the USGS is seeking? ? Question 3: Do USGS employees perceive that the USGS is a rewarding place to work? ? Question 4: What actions can and should be taken to enhance the USGS work environment? To begin the study, a conceptual model of a rewarding USGS environment was developed to test assumptions about a rewarding work environment. The Rewarding Environment model identifies the key components that are thought to contribute to a rewarding work environment and the valued outcomes that are thought to result from having a rewarding work environment. The 2002 Organizational Assessment Survey (OAS) was used as the primary data source for the study because it provided the most readily available data. Additional survey data were included as they

    Background It is anecdotally recognized that commercial gym users assume supplements in order to improve performance or health. However, dietary behaviours of people and athletes attending commercial gyms have been poorly studied. The exact amount and frequency of dietary supplements consumption are still needed to be investigated. The main purpose of this study is to understand the quantity and quality of food intake, as well as dietary supplementation in people attending commercial gyms. Secondly to compare the city centre and the suburbs of Palermo, Italy. Methods A face-to-face questionnaire was administered to 561 subjects, 207 from the city centre (CC) and 354 from the suburbs (SB) of Palermo, Italy. Frequency of protein supplements use and association with dietary behaviours were investigated. Subsequently, the frequency distribution was used for demographic assessment. Results Frequency of protein consumption was similar in both groups (30% for CC and 28.8% for SB). Males show greater consumption percentages than females (30.5% in males and 6.9% in females). Milk and chicken are the most frequently consumed foods. Data show that non-supplement users (NSU) consume significantly more snacks and bakery products than supplement users (SU) (P gym users is 30% for the CC and 28.8% for the SB. Significant differences were found between CC and SB females, underlining an interesting discrepancy, indicating to dietary supplement industries regarding regional implications. Subjects that use protein supplements also consume larger quantities of high protein food compared to NSU. NSU also eat higher proportions of unhealthy food compared to SU. PMID:24976800

    To evaluate the cost-effectiveness of Age-Related Eye Disease Study (AREDS) 1 & 2 supplements in patients with either bilateral intermediate age-related macular degeneration, AREDS category 3, or unilateral neovascular age-related macular degeneration AMD (nAMD), AREDS category 4. A patient-level health state transition model based on levels of visual acuity in the better-seeing eye was constructed to simulate the costs and consequences of patients taking AREDS vitamin supplements. UK National Health Service (NHS). The model was populated with data from AREDS and real-world outcomes and resource use from a prospective multicentre national nAMD database study containing 92 976 ranibizumab treatment episodes. Two treatment approaches were compared: immediate intervention with AREDS supplements or no supplements. quality-adjusted life years (QALYs) and healthcare costs were accrued for each strategy, and incremental costs and QALYs were calculated for the lifetime of the patient. One-way and probabilistic sensitivity analyses were employed to test the uncertainty of the model. For AREDS category 3, the incremental cost-effectiveness ratio was £30 197. For AREDS category 4 compared with no intervention, AREDS supplements are more effective (10.59 vs 10.43 QALYs) and less costly (£52 074 vs 54 900) over the lifetime of the patient. The recommendation to publicly fund AREDS supplements to category 3 patients would depend on the healthcare system willingness to pay. In contrast, initiating AREDS supplements in AREDS category 4 patients is both cost saving and more effective than no supplement use and should therefore be considered in public health policy. © Article author(s) (or their employer(s) unless otherwise stated in the text of the article) 2018.

    Full Text Available Objective: to investigate the effects of preoperative fasting abbreviation with oral supplementation with carbohydrate in the evolution of grip strength in patients undergoing cholecystectomy by laparotomy. Methods : we conducted a clinical, randomizeddouble blind study with adult female patients, aged 18-60 years. Patients were divided into two groups: Control Group, with fasting prescription 6-8h until the time of operation; and Intervention Group, which received prescription of fasting for solids 6-8h before surgery, but ingested an oral supplement containing 12.5% carbohydrate, six (400ml and two (200ml hours before theprocedure. The handgrip strength was measured in both hands in both groups, at patient's admission (6h before surgery, the immediate pre-operative time (1h before surgery and 12-18h postoperatively. Results : we analyzed 27 patients, 14 in the intervention group and 13 in the control group. There was no mortality. The handgrip strength (mean [standard deviation] was significantly higher in the intervention group in the three periods studied, in at least one hand: preoperatively in the dominant hand (27.8 [2.6] vs 24.1 [3.7] kg; p=0.04, in the immediate preoperative in both hands, and postoperatively in the non-dominant hand (28.5 [3.0] vs 21.3 [5.9] kg; p=0.01. Conclusion : the abbreviation of preoperative fasting to two hours with drink containing carbohydrate improves muscle function in the perioperative period.

    Alcohol consumption is linked to increased breast cancer risk. Since oestrogens increase breast cancer risk, possibly through oxidative damage, and we have shown that alcohol consumption increases serum oestrogens, we tested whether moderate alcohol supplementation increased oxidative DNA damage among healthy postmenopausal women not on hormone replacement therapy in a randomized controlled crossover study. We used serum 5-hydroxymethyl-2-deoxyuridine (5-HMdU) autoantibodies (aAbs) as a marker of oxidative DNA damage. The results showed no evidence for increased or decreased levels of oxidative DNA damage among women who consumed 15 g or 30 g alcohol per day for 8 weeks compared with women in the 0 g alcohol group. We conclude that among healthy women, it is possible that an 8-week trial of moderate alcohol supplementation might be too short to make enough 5-HMdU aAbs to compare differences by alcohol dose. In future studies, a panel of biomarkers for DNA damage should be used.

    Athletes who train indoors during the winter months exhibit low serum 25-hydroxyvitamin D [25(OH)D] concentrations due to a lack of sunlight exposure. This has been linked to impaired exercise performance. The purpose of this study was to assess the effects of oral vitamin D₃ supplementation on selected physical fitness and injury parameters in elite ballet dancers. Controlled prospective study. 24 elite classical ballet dancers (intervention n=17; control n=7) participated in a controlled 4-month oral supplementation of vitamin D₃ (2000 IU per day). Isometric muscular strength and vertical jump height were measured pre and post intervention. Injury occurrence during the intervention period was also recorded by the in-house medical team. Repeated measures ANOVA and Mann-Whitney-U statistical tests were used and significance was set at p ≤ 0.05. Significant increases were noted for the intervention group for isometric strength (18.7%, pballet dancers. Copyright © 2013 Sports Medicine Australia. Published by Elsevier Ltd.

    To examine the effect of a combined dietary supplement containing fish oil, lactoferrin, zinc, vitamin C, lutein, vitamin E, γ-aminobutanoic acid, and Enterococcus faecium WB2000 on dry eye. A preliminary study in a rat model and a prospective, randomized, double-blind, placebo-controlled study in humans were conducted. Forty Japanese volunteers aged 22 to 59 years were randomized into combined dietary supplement (2 capsules/day; 20 participants) and placebo (vehicle; 19 participants) groups and treated once daily for 8 weeks. Rats received the combined dietary supplement components (10 or 50 mg/kg orally) or vehicle (2% DMSO), and dry eye was mechanically induced for 2 days. Tear production was measured in rats after dry eye was induced. Humans were assessed at baseline and weeks 4 and 8 post-supplementation based on keratoconjunctival epithelial damage; fluorescein tear film breakup time; tear production; biochemical data; information regarding subjective dry eye symptoms by answering a questionnaire; and information regarding adverse events via medical interviews. Supplementation dose-dependently mitigated the decrease in tear production in rats. Among subjects with confirmed dry eye, clinical symptoms improved at weeks 4 and 8 more significantly in the supplementation group than in the placebo group (Peye symptoms.

    Supplemental Instruction (SI) is a programme that is attached to difficult courses with the objective of increasing student performance and retention. However, an SI programme also has the potential to increase overall student performance and retention during the first critical year if applied to introductory courses. In this study the latter objective is investigated in an engineering educational environment. The study shows that an SI programme attached to difficult first semester courses for new engineering students has substantial positive effects on both first-year student performance and retention. Both male and female students appear to benefit from attending SI to the same extent. Some potential reasons for these improved first-year student performances are that attendance at SI sessions appears to lead to improved self-confidence, a broader network of study partners, improved study strategies and problem-solving skills and an increased ability to critically review material and work with others.

    Full Text Available Abstract Background The objective was to study nutritional supplement use among young elite UK athletes to establish whether a rationale versus practice incongruence exists, and to investigate the sources of information. Survey data were analysed for association between supplements used and motives for using such substances among young athletes along with the sources of advice and literature precedents on supplement effects. Methods Participants were elite UK male and female athletes, within the age range between 12 and 21 (n = 403, mean age 17.66 ± 1.99. Associations between type of supplements and reasons for using supplements were tested by calculating Pearson's χ2 and the strength of these symmetric associations shown by phi (ϕ association coefficients. Results Single supplement use was reported by 48.1%, with energy drinks being the most popular, consumed by 41.7% of all athletes and 86.6% of the supplement users in the sample. No agreement was observed between athletes' rationale and behaviour in relation to nutritional supplements except for creatine. Among health professionals, nutritionists and physiotherapists, followed by coaches, were most frequently consulted. Answers regarding reasons and supplements used showed incongruence and suggest widespread misinformation regarding supplements and their effects is an issue for the young athlete. Conclusion Widespread supplement taking behaviour was evidenced in the young elite athlete population with the most notable congruence between rationale and practice among young athletes being performance-related. Young athletes in the present sample appear to be less 'health conscious' and more 'performance focused' than their adult counterparts. Further research, using a full list of supplements, is warranted to test the hypothesis that health consciousness is less dominant in supplement choice by young athletes.

    As a part of health survey in relation to air pollution, 16 smokers(11 from 'high' and 5 from 'low' zone) were studied with extensive serial lung functions, chest radiography and radioaerosol lung scanning. The clinical diagnosis were chronic bronchitis(COPD) in 9 subjects; but others (4 'High' and 3 'Low') were considered normal. The values of FVC, FEV were normal in most of these three groups, but FEV 1 /FVC percent values were lower in subjects from 'high' zone.The functional declines were higher in normals of 'high' zone. Radioaerosol (ventilation) scans (with technetium 99 ) showed a normal picture in 2 COPD and 3 normal subjects; in 3 COPD and 1 normal subjects the abnormalities were definite. For perfusion scans, 2 COPD and 3 normal subjects showed a normal pattern while definite abnormalities were seen in 1 COPD and 1 normal subjects. Lung scans may pick up abnormalities in normal smokers at an early stage. (author)

    Full Text Available Abstract Background Supplemental vitamin D modulates inflammatory cytokines and skeletal muscle function, but results are inconsistent. It is unknown if these inconsistencies are dependent on the supplemental dose of vitamin D. Therefore, the purpose of this study was to identify the influence of different doses of supplemental vitamin D on inflammatory cytokines and muscular strength in young adults. Methods Men (n = 15 and women (n = 15 received a daily placebo or vitamin D supplement (200 or 4000 IU for 28-d during the winter. Serum 25-hydroxyvitamin D (25(OHD, cytokine concentrations and muscular (leg strength measurements were performed prior to and during supplementation. Statistical significance of data were assessed with a two-way (time, treatment analysis of variance (ANOVA with repeated measures, followed by a Tukey's Honestly Significant Difference to test multiple pairwise comparisons. Results Upon enrollment, 63% of the subjects were vitamin D sufficient (serum 25(OHD ≥ 30 ng/ml. Serum 25(OHD and interleukin (IL-5 decreased (P P P P Conclusion In young adults who were vitamin D sufficient prior to supplementation, we conclude that a low-daily dose of supplemental vitamin D prevents serum 25(OHD and IL-5 concentration decreases, and that muscular strength does not parallel the 25(OHD increase induced by a high-daily dose of supplemental vitamin D. Considering that IL-5 protects against viruses and bacterial infections, these findings could have a broad physiological importance regarding the ability of vitamin D sufficiency to mediate the immune systems protection against infection.

    2017-03-01

    Full Text Available There is a current trend in endurance sports to move athletes towards a low-carbohydrate diet or use periods of low carbohydrate consumption to increase both health and performance. As a result, a market is developing for sports supplements to provide nutritional support during training and racing for athletes who follow a low-carbohydrate lifestyle. PHAT FIBRE (PF is a powdered sports supplement that includes medium-chain triglycerides suspended in a digestion-resistant carbohydrate and is tailored to the needs of low-carb athletes. Eleven healthy participants were administered 25 g of PF after an overnight fast. After 30 minutes, median blood glucose increased by 6 mg/dl from 94 mg/dl to 100 mg/dl (p = 0.002. At the same time points, median blood beta-hydroxybutyrate (BHB increased from 0.3 mmol/L to 0.5 mmol/L. The increase in BHB was significant (p = 0.02 after excluding one outlier who had elevated levels of fasting BHB. Insulin levels did not change significantly at any point during the study. In a single participant, a revised formulation of PF (PFv2 produced a 0.6 mmol/L increase in BHB with no effect on blood glucose. These data suggest that PF can provide a source of energy for the low-carb athlete by supporting ketone production without negatively impacting insulin or blood glucose levels.

    Objective: To evaluate the effectiveness of a novel oral supplement, Forti5 ® , containing green tea extract, omega 3 and 6 fatty acids, cholecalciferol, melatonin, beta-sitosterol, and soy isoflavones, and in the management of subjects with androgenetic alopecia. Design: A prospective case series of 10 subjects. Setting: Open-label, evaluator-blinded, proof-of-concept study. Participants: Ten adult subjects with androgenetic alopecia completed the study. Subjects were not allowed to use oral or topical hair growth products in the 24 weeks preceding the study or during the study. The nutritional supplement was administered at a dosage of two tablets daily for 24 weeks. Measurements: Clinical evaluations were performed at baseline and at 24 weeks. Efficacy was evaluated using hair mass index measured by cross section trichometer, terminal hair count measured with dermoscopy and Investigator Global Photography Assessment. Results: Overall 80 percent of subjects (8/10) were rated as improved after 24 weeks of supplementation (mean change of +1.4 equivalent to slightly-to-moderately increased). Forty percent of subjects (4/10) were rated as moderately improved (2+), and 10 percent (1/10) were rated as greatly improved (3+). There was a significant improvement in terminal hair count (mean increase of 5.9% or 4.2 more terminal hairs in the area examined, p =0.014) and in Hair Mass Index (mean increase of 9.5% or 4.5 higher Hair Mass Index, p =0.003). Conclusion: These preliminary results indicate that Forti5 ® a novel nutritional supplement that contains cholecalciferol, omega 3 and 6 fatty acids, melatonin, antioxidants, and botanical 5-alpha reductase inhibitors, may be a useful adjunct in the treatment of androgenetic alopecia.

    The health benefits of omega-3 fatty acids from fish are well known, and fish oil supplements are used widely in a preventive manner to compensate the low intake in the general population. The aim of this open-label study was to determine if consumption of a high potency fish oil supplement could improve blood levels of eicosapentaenoic acid (EPA) and docosahexaenoic acid (DHA) and impact SF-12 mental and physical health scores in healthy adults. A novel virtual clinical research organization was used along with the HS-Omega-3 Index, a measure of EPA and DHA in red blood cell membranes expressed as a percentage of total fatty acids that has been shown to correlate with a reduction in cardiovascular and other risk factors. Briefly, adult subjects (mean age 44 years) were recruited from among U.S. health food store employees and supplemented with 1.1 g/d of omega-3 from fish oil (756 mg EPA, 228 mg DHA, Minami Nutrition MorEPA Platinum) for 120 days (n = 157). Omega-3 status and mental health scores increased with supplementation (p < 0.001), while physical health scores remained unchanged. The use of a virtual, web-based platform shows considerable potential for engaging in clinical research with normal, healthy subjects. A high potency fish oil supplement may further improve omega-3 status in a healthy population regularly consuming an omega-3 supplement.

Aim: To study the effect of: bi-weekly supplementation of IFA with and without Albendazole administration on the status of hemoglobin level in college going adolescent girls. Material and methods:  An interventional study was conducted among college going girls in Agra in the age group of 16-19 years (n=300 who were randomly selected. Their Hemoglobin levels were estimated before and after intervention by the Cynmeth-hemoglobin method using Drabkin’s solution. Three groups [two study A and B and one control] of hundred girls each were randomly constituted. To the study groups, supervised bi-weekly IFA with and without Albendazole were administered respectively for three months. Data collected was analyzed using suitable statistical tools. Results &Discussion: The overall prevalence of anemia was 65.3%.The initial prevalence in study group  reduced significantly from 80.7% to 35.5% whereas in study group B it reduced from 73.5% to 58.8% and in control it remained almost same 84.3% and 81.2% pre and post intervention respectively. The mean Hemoglobin rise observed in the study group A and B was 2.5gm/dl and 2.3 gm/dl respectively while in control group fall in the mean Hb was observed (0.1gm/dl. Conclusion: The prevalence of anemia in adolescent girls is high. Supervised IFA therapy twice a week is an effective strategy to lower the prevalence of anemia either combined or uncombined with Albendazole.

    Full Text Available Memory dysfunction is a common complaint following heart surgery and may be related to a diffuse ischemic state induced by microemboli dislodged during the procedure. Ischemia can induce damage by a number of mechanisms, including oxidative stress. Because pomegranates contain a variety of polyphenols with antioxidant and other potentially beneficial effects, we tested whether supplementation with a pomegranate extract before and after heart surgery could protect against postoperative cognitive dysfunction. Patients undergoing elective coronary artery bypass graft and/or valve surgery were given either 2 g of pomegranate extract (in 2 POMx pills or placebo (pills containing no pomegranate ingredients per day from one week before surgery to 6 weeks after surgery. The patients were also administered a battery of neuropsychological tests to assess memory function at 1 week before surgery (baseline, 2 weeks after surgery, and 6 weeks after surgery. The placebo group had significant deficits in postsurgery memory retention, and the pomegranate treatment not only protected against this effect, but also actually improved memory retention performance for up to 6 weeks after surgery as compared to presurgery baseline performance.

    Probiotics are live microorganisms that, when administered in sufficient doses, provide health benefits on the host. The United States Food and Drug Administration (FDA) requires phase I safety studies for probiotics when the intended use of the product is as a drug. The purpose of the study was to determine the safety of Bifidobacterium animalis subsp lactis (B. lactis) strain BB-12 (BB-12)-supplemented yogurt when consumed by a generally healthy group of adults who were prescribed a 10-day course of antibiotics for a respiratory infection. Secondary aims were to assess the ability of BB-12 to affect the expression of whole blood immune markers associated with cell activation and inflammatory response. A phase I, double-blinded, randomized controlled study was conducted in compliance with FDA guidelines for an Investigational New Drug (IND). Forty participants were randomly assigned to consume 4 ounces of either BB-12 -supplemented yogurt or non-supplemented control yogurt daily for 10 d. The primary outcome was to assess safety and tolerability, assessed by the number of reported adverse events. A total of 165 non-serious adverse events were reported, with no differences between the control and BB-12 groups. When compared to the control group, B lactis fecal levels were modestly higher in the BB-12-supplemented group. In a small subset of patients, changes in whole blood expression of genes associated with regulation and activation of immune cells were detected in the BB-12-supplemented group. BB-12-supplemented yogurt is safe and well tolerated when consumed by healthy adults concurrently taking antibiotics. This study will form the basis for future randomized clinical trials investigating the potential immunomodulatory effects of BB-12-supplemented yogurt in a variety of disease states.

Patients and methods: A total of 1,255 patients with glaucoma and dry eye symptoms related to antiglaucoma topical medication participated in an open-label, uncontrolled, prospective, and multicenter study and were instructed to take three capsules a day of the nutraceutical formulation (Brudypio® 1.5 g for 12 weeks. Dry eye symptoms (graded as 0–3 [none to severe, respectively], conjunctival hyperemia, tear breakup time, Schirmer I test, Oxford grading scheme, and intraocular pressure were assessed. Results: After 12 weeks of administration of the dietary supplement, all dry eye symptoms improved significantly (P<0.001 (mean 1.3 vs 0.6 for scratching, 1.4 vs 0.7 for stinging sensation, 1.6 vs 0.7 for grittiness, 1.0 vs 0.4 for tired eyes, 1.1 vs 0.5 for grating sensation, and 0.8 vs 0.3 for blurry vision. The Schirmer test scores and the tear breakup time also increased significantly. There was an increase in the percentage of patients grading 0–I in the Oxford scale and a decrease in those grading IV–V. Compliance was recorded in 62.5% of patients. In compliant patients, the mean differences at 12 weeks vs baseline of dry eye symptoms were statistically significant as compared to noncompliant patients. Conclusion: Dietary supplementation with Brudypio® may be a clinically valuable additional option for the treatment of dry eye syndrome in patients with glaucoma using antiglaucoma eye drops. These results require confirmation with an appropriately designed randomized controlled study

    Lead present in calcium supplements is of grave concern as some lead levels have been measured up to the extent of regulatory limit set by the United States. Calcium supplements inevitably get contaminated with lead as both are naturally occurring elements. Therefore, it is imperative to indicate its level in these supplements in order to create awareness among consumers. In this study, a sophisticated analytical technique, atomic absorption spectrometry was used to analyze Pb contents in 27 commonly consumed Ca supplements manufactured by different national and multinational companies. The daily intake of lead through these supplements was calculated. Only 10% of the calcium supplements analyzed met the criteria of acceptable Pb levels (1.5 mu g/daily dose) in supplements/consumer products set by the United States. It was also found that Pb intake was highest in chelated calcium supplements 28.5 mu g/daily dose, whereas lowest 0.47 mu g/daily dose through calcium supplements with vitamin D formulation. In order to validate our results from the study conducted, IAEA-certified reference material (animal bone, H-5) was analyzed for its Pb levels. The levels of Pb determined were quite in good agreement with the certified values. (author)

Multivariate logistic regression analysis was conducted to adjust for relevant confounders.A total of 1755 neonates (Epoch I vs. II: 835 vs. 920 with comparable gestation and birth weights were admitted. There was a significant reduction in NEC ≥ Stage II: 3% vs. 1%, adjusted odds ratio (aOR = 0.43 (95%CI: 0.21-0.87; 'NEC ≥ Stage II or all-cause mortality': 9% vs. 5%, aOR = 0.53 (95%CI: 0.32-0.88; but not all-cause mortality alone: 7% vs. 4%, aOR = 0.58 (95% CI: 0.31-1.06 in Epoch II. The benefits in neonates <28 weeks did not reach statistical significance: NEC ≥ Stage II: 6% vs. 3%, aOR 0.51 (95%CI: 0.20-1.27, 'NEC ≥ Stage II or all-cause mortality', 21% vs. 14%, aOR = 0.59 (95%CI: 0.29-1.18; all-cause mortality: 17% vs. 11%, aOR = 0.63 (95%CI: 0.28-1.41. There was no probiotic sepsis.RPS with Bifidobacterium breve M-16V was associated with decreased NEC≥ Stage II and 'NEC≥ Stage II or all-cause mortality' in neonates <34 weeks. Large sample size is required to assess the potential benefits of RPS in neonates <28 weeks.

  4. Factors that contribute to biomarker responses in humans including a study in individuals taking Vitamin C supplementation.

    It is possible in many situations to identify humans exposed to potentially toxic materials in the workplace and in the environment. As in most human studies, there tends to be a high degree of interindividual variability in response to chemical insults. Some non-exposed control individuals exhibit as high a level of damage as some exposed individuals and some of these have levels of damage as low as many of the controls. Thus, it is only the mean values of the groups that can substantiate an exposure-related problem; the data on an individual basis are still of limited use. While human lymphocytes remain the most popular cell type for monitoring purposes, sperm, buccal, nasal, epithelial and placental cells are also used. However, for interpretation of responses, the issue of confounding factors must be addressed. There are endogenous confounding factors, such as age, gender, and genetic make-up and exogenous ones, including lifestyle habits (smoking, drinking, etc.) There are biomarkers of exposure, effect/response and susceptibility and the last may be influenced by the genotype and polymorphism genes existing in a population. From our own studies, confounding effects on cytogenetic damage and ras oncoproteins will be considered in relation to workers exposed to vinyl chloride and petroleum emissions and to volunteers taking Vitamin C supplementation. Smoking history, exposure and duration of employment affected the worker studies. For petroleum emissions, so did gender and season of exposure. For the non-smoking volunteer Vitamin C supplementation study, cholesterol levels, plasma Vitamin C levels, lipid peroxidation products and DNA damage in the Comet assay were also measured. Gender affected differences in Vitamin C levels, antioxidant capacity and the number of chromosome aberrations induced by bleomycin challenge in vitro. The results were the same for both high and low cholesterol subjects. The relationship between biomarkers and the various factors which

    Full Text Available Human and experimental studies have revealed putative neuroprotective and pro-cognitive effects of omega-3 polyunsaturated fatty acids (n-3 PUFA in aging, evidencing positive correlations between peripheral n-3 PUFA levels and regional grey matter (GM volume, as well as negative correlations between dietary n-3 PUFA levels and cognitive deficits. We recently showed that n-3 PUFA supplemented aged mice exhibit better hippocampal-dependent mnesic functions, along with enhanced cellular plasticity and reduced neurodegeneration, thus supporting a role of n-3 PUFA supplementation in preventing cognitive decline during aging. To corroborate these initial results and develop new evidence on the effects of n-3 PUFA supplementation on brain substrates at macro-scale level, here we expanded behavioral analyses to the emotional domain (anxiety and coping skills, and carried out a fine-grained regional GM volumetric mapping by using high-resolution MRI-based voxel-based morphometry. The behavioral effects of 8 week n-3 PUFA supplementation were measured on cognitive (discriminative, spatial and social and emotional (anxiety and coping abilities of aged (19 month-old at the onset of study C57B6/J mice. n-3 PUFA supplemented mice showed better mnesic performances as well as increased active coping skills. Importantly, these effects were associated with enlarged regional hippocampal, retrosplenial and prefrontal GM volumes, and with increased post mortem n-3 PUFA brain levels. These findings indicate that increased dietary n-3 PUFA intake in normal aging can improve fronto-hippocampal GM structure and function, an effect present also when the supplementation starts at late age. Our data are consistent with a protective role of n-3 PUFA supplementation in counteracting cognitive decline, emotional dysfunctions and brain atrophy.

  6. Issues in Nutrition: Dietary Supplements.

    The majority of American adults report use of one or more dietary supplements every day or occasionally. The Dietary Supplement Health and Education Act of 1994 defines dietary supplements and regulates their manufacture and distribution. One of the most commonly used supplements is vitamin D. Measurement of serum levels of vitamin D must be undertaken with the caveats that different laboratories define normal levels differently, and that there is rarely a clinical correlation with the actual level. Patients should understand that supplements should not be used to excess, as there are toxicities and other adverse effects associated with most of them. There currently is considerable research being performed on probiotics and how the gut microbiome affects health and disease states. Protein supplements may be useful in reducing mortality rates in elderly patients but they do not appear to increase quality of life. If used, protein supplements should contain essential amino acids. Casein and whey supplements, derived from dairy sources, help transport essential amino acids to tissues. Although there have been many studies investigating the role of vitamin supplements in disease prevention, there have been few conclusive positive results.

    Background: Dietary fish oils, rich in long-chain n-3 (ω-3) fatty acids (FAs) [e.g., docosahexaenoic acid (DHA, 22:6n-3) and eicosapentaenoic acid (EPA, 20:5n-3)], modulate inflammatory reactions through various mechanisms, including gene expression, which is measured as messenger RNA concentration. However, the effects of long-term treatment of humans with DHA and EPA on various epigenetic factors-such as DNA methylation, which controls messenger RNA generation-are poorly described. Objective: We wanted to determine the effects of 6 mo of dietary supplementation with an n-3 FA preparation rich in DHA on global DNA methylation of peripheral blood leukocytes (PBLs) and the relation to plasma EPA and DHA concentrations in Alzheimer disease (AD) patients. Design: In the present study, DNA methylation in four 5'-cytosine-phosphate-guanine-3' (CpG) sites of long interspersed nuclear element-1 repetitive sequences was assessed in a group of 63 patients (30 given the n-3 FA preparation and 33 given placebo) as an estimation of the global DNA methylation in blood cells. Patients originated from the randomized, double-blind, placebo-controlled OmegAD study, in which 174 AD patients received either 1.7 g DHA and 0.6 g EPA (the n-3 FA group) or placebo daily for 6 mo. Results: At 6 mo, the n-3 FA group displayed marked increases in DHA and EPA plasma concentrations (2.6- and 3.5-fold), as well as decreased methylation in 2 out of 4 CpG sites ( P DHA concentration, and were not related to apolipoprotein E-4 allele frequency. Conclusion: Supplementation with n-3 FA for 6 mo was associated with global DNA hypomethylation in PBLs. Our data may be of importance in measuring various effects of marine oils, including gene expression, in patients with AD and in other patients taking n-3 FA supplements.

    Full Text Available Sustainability education (SE is included in school curricula to integrate the principles, values, and practices of sustainable development (SD into all education. This study investigates lower secondary school subject teachers as educators for sustainability. A survey was used to study the perceptions of 442 subject teachers from 49 schools in Finland. There were significant differences between the subject teachers’ perceptions of their SE competence, and the frequency with which they used different dimensions of SE (ecological, economic, social, well-being, cultural in their teaching varied. Teachers’ age had a small effect, but gender, school, and its residential location were nonsignificant factors. Teachers could be roughly classified into three different subgroups according to their perceptions of the role of SE in their teaching; those who considered three SE dimensions rather often and used holistic sustainability approaches in their teaching (biology, geography, history; those who considered two or three dimensions often but were not active in holistic teaching (mother tongue, religion, visual arts, crafts, music, physical and health education, and home economics and those who used one SE dimension or consider only one holistic approach in their teaching (mathematics, physics, chemistry and language. Subject teachers’ awareness of their SE competence is important to encourage them to plan and implement discipline-based and interdisciplinary SE in their teaching. The specific SE expertise of subject teachers should be taken into account in teacher training and education.

    Previous studies that have investigated the association between B-vitamin supplement use and risk for cataract yield conflicting results. The aim of this study was to examine the association between use of high-dose B-vitamin supplements (approximately 10 times recommended daily intake) and risk for age-related cataract in a population-based prospective study of 13 757 women from the Swedish Mammography Cohort and 22 823 men from the Cohort of Swedish Men. Dietary supplement use and potential confounders were assessed using a questionnaire at baseline. Information on cataract diagnosis and extraction was obtained through linkage to registers. During the follow-up period between January 1998 and December 2011, we identified 8395 cataract cases (3851 for women and 4544 for men). The use of B vitamins plus other supplements and B vitamins only was associated with 9 % (95 % CI 2, 17) and 27 % (95 % CI 12, 43) increased risk for cataract, respectively. The hazard ratios for use of B vitamins only and risk for cataract stratified by different age groups were as follows: B-vitamin supplements was associated with an increased risk for cataract. This association might be confined to younger participants.

    Persistent diarrhoea (PD) is globally recognized as a major cause of childhood morbidity and mortality. PD is closely associated with malnutrition and nutrition rehabilitation especially domiciliary dietary therapy posses a therapeutic challenge. While there has been success in managing such children with locally home available traditional diets, there has been concern with the potential of associated micronutrient especially zinc deficiency. We are evaluating the impact of zinc supplementation of a traditional rice-lentil (khitchri) and yogurt diet in malnourished children with PD in randomized double blind study. In addition to the impact on weight gain, stool output and body composition, we will evaluate whole body protein kinetics using the modified CRP protocol [employing 15 N-glycine, H 13 Co 3 and 1- 13 C leucine]. We will also estimate the effect of coexisting illnesses, especially febrile episodes on nutritional recovery and protein metabolism. (author). 20 refs, 5 figs, 1 tab

  11. A case study of discordant overlapping meta-analyses: vitamin d supplements and fracture.

    Mark J Bolland

    Full Text Available BACKGROUND: Overlapping meta-analyses on the same topic are now very common, and discordant results often occur. To explore why discordant results arise, we examined a common topic for overlapping meta-analyses- vitamin D supplements and fracture. METHODS AND FINDINGS: We identified 24 meta-analyses of vitamin D (with or without calcium and fracture in a PubMed search in October 2013, and analysed a sample of 7 meta-analyses in the highest ranking general medicine journals. We used the AMSTAR tool to assess the quality of the meta-analyses, and compared their methodologies, analytic techniques and results. Applying the AMSTAR tool suggested the meta-analyses were generally of high quality. Despite this, there were important differences in trial selection, data extraction, and analytical methods that were only apparent after detailed assessment. 25 trials were included in at least one meta-analysis. Four meta-analyses included all eligible trials according to the stated inclusion and exclusion criteria, but the other 3 meta-analyses "missed" between 3 and 8 trials, and 2 meta-analyses included apparently ineligible trials. The relative risks used for individual trials differed between meta-analyses for total fracture in 10 of 15 trials, and for hip fracture in 6 of 12 trials, because of different outcome definitions and analytic approaches. The majority of differences (11/16 led to more favourable estimates of vitamin D efficacy compared to estimates derived from unadjusted intention-to-treat analyses using all randomised participants. The conclusions of the meta-analyses were discordant, ranging from strong statements that vitamin D prevents fractures to equally strong statements that vitamin D without calcium does not prevent fractures. CONCLUSIONS: Substantial differences in trial selection, outcome definition and analytic methods between overlapping meta-analyses led to discordant estimates of the efficacy of vitamin D for fracture prevention

    This report presents physical property logs of core samples from an offshore area near Eureka, CA. The cores were obtained as part of the STRATAFORM Program (Nittrouer and Kravitz, 1995, 1996), a study investigating how present sedimentation and sediment transport processes influence long-term stratigraphic sequences preserved in the geologic record. The core samples were collected during four separate research cruises to the northern California study area, and data shown in the logs of the cores were collected using a multi-sensor whole core logger. The physical properties collected are useful in identifying stratigraphic units, ground-truthing acoustic imagery and sub-bottom profiles, and in understanding mass movement processes. STRATA FORmation on Margins was initiated in 1994 by the Office of Naval Research, Marine Geology and Geophysics Department as a coordinated multi-investigator study of continental-margin sediment transport processes and stratigraphy (Nittrouer and Kravitz, 1996). The program is investigating the stratigraphic signature of the shelf and slope parts of the continental margins, and is designed to provide a better understanding of the sedimentary record and a better prediction of strata. Specifically, the goals of the STRATAFORM Program are to (Nittrouer and Kravitz, 1995): - determine the geological relevance of short-term physical processes that erode, transport, and deposit particles and those processes that subsequently rework the seabed over time scales - improve capabilities for identifying the processes that form the strata observed within the upper ~100 m of the seabed commonly representing 104-106 years of sedimentation. - synthesize this knowledge and bridge the gap between time scales of sedimentary processes and those of sequence stratigraphy. The STRATAFORM Program is divided into studies of the continental shelf and the continental slope; the geotechnical group within the U.S. Geological Survey provides support to both parts

    The role of plasma glutamine concentration and glutamine supplementation on immunosuppression was investigated in combat athletes. Twenty-three male athletes were randomly assigned to receive glutamine (21 g/day, n=12) or placebo (ovalbumin, n=11) for 10 days. Six athletes who did not lose weight served as controls. Athletes were assessed 21 days before (-21d), 1 day before (-1d) and 5 days after (+5d) a competition. Weight reduction was similar between glutamine (-8.2%± 4.1%) and placebo (-8.5%±2.4%) and negligible in control (-0.6%±1.4%). In both weight-loss groups, the majority of athletes reported symptoms of upper respiratory symptoms, as assessed by the Wisconsin upper respiratory symptom survey questionnaire. Only two athletes reported symptoms in the control group. Immune cell function remained unchanged throughout the study except for an increase in neutrophil phagocytic activity (placebo: -21d=5,251±2,986; -1d=17,428±22,374; +5d=21,125±21,934; glutamine: -21d=6,096±3,549; -1d=11,029±17,113; +5d=28,186±21,032 FI) and a minor change in monocyte phagocytic activity (placebo: -21d=4,421±3,634; -1d=3,329±6,283; +5d=3,243± 2,553; glutamine: -21d=4,051±3,186; -1d=3,106±2,625; +5d=4,981± 4,598) in both glutamine and placebo after weight loss. Plasma glutamine and cortisol remained unchanged across the study. creatine kinase levels were increased in placebo (-21d=125.2±54.1; -1d=187.2± 73.5; +5d=111.3±59.1 U/L) but not in glutamine (-21d=136.2±58.2; -1d= 168.8±65.0; +5d=129.7±64.0 U/L). Rapid weight loss increased the frequency and severity of infection symptoms, but this was neither associated with plasma glutamine depletion nor counteracted by glutamine supplementation.

    Bailey, Regan L.; Gahche, Jaime J.; Thomas, Paul R.; Dwyer, Johanna T.

    2013-01-01

    Background: Dietary supplements are used by one-third of children. We examined motivations for supplement use in children, the types of products used by motivations, and the role of physicians and health care practitioners in guiding choices about supplements. Methods: We examined motivations for dietary supplement use reported for children (from birth to 19 y of age; n = 8,245) using the National Health and Nutrition Examination Survey 2007–2010. Results: Dietary supplements were used by 31% of children; many different reasons were given as follows: to “improve overall health” (41%), to “maintain health” (37%), for “supplementing the diet” (23%), to “prevent health problems” (20%), and to “boost immunity” (14%). Most children (~90%) who use dietary supplements use a multivitamin–mineral or multivitamin product. Supplement users tend to be non-Hispanic white, have higher family incomes, report more physical activity, and have health insurance. Only a small group of supplements used by children (15%) were based on the recommendation of a physician or other health care provider. Conclusion: Most supplements used by children are not under the recommendation of a health care provider. The most common reasons for use of supplements in children are for health promotion, yet little scientific data support this notion in nutrient-replete children. PMID:24002333

    The present study, taking a resource-oriented approach to mental health, aimed at investigating mental resilience and its determinants among undergraduate physiotherapy students using quantitative and qualitative tools. A questionnaire-based cross-sectional survey supplemented by 2 focus groups. One university in Hungary. 130 physiotherapy students at years 1, 2, and 3. Sense of coherence, a measure of dynamic self-esteem, as well as social support from family and peers were used to assess mental well-being. A screening instrument for psychological morbidity and perceived stress were used as deficiency-oriented approaches. Student opinions were gathered on positive and negative determinants of mental health. Resilience was lower [mean difference 4.8 (95% CI -3.4; 13.1)], and the occurrence of psychological morbidity (32.5% vs. 0%) was higher among female compared to male students. However, the proportion of students fully supported by their peers was higher among females (63% vs. 37.5%). Female students, unlike their male counterparts, experienced higher stress compared to their peers in the general population. Social support declined as students progressed in their studies though this proved to be the most important protective factor for their mental well-being. Results were fed back to the course organizers recommending the implementation of an evidence-based method to improve social support as delineated by the Guide to Community Preventive Services of the US the outcomes of which are to be seen in the future.

    Full Text Available No study has concurrently measured changes in free-living whole body protein metabolism and exercise performance during recovery from an acute bout of resistance exercise. We aimed to determine if whey protein ingestion enhances whole body net protein balance and recovery of exercise performance during overnight (10 h and 24 h recovery after whole body resistance exercise in trained men. In a double-blind crossover design, 12 trained men (76 ± 8 kg, 24 ± 4 years old, 14% ± 5% body fat; means ± standard deviation (SD performed resistance exercise in the evening prior to consuming either 25 g of whey protein (PRO; MuscleTech 100% Whey or an energy-matched placebo (CHO immediately post-exercise (0 h, and again the following morning (~10 h of recovery. A third randomized trial, completed by the same participants, involving no exercise and no supplement served as a rested control trial (Rest. Participants ingested [15N]glycine to determine whole body protein kinetics and net protein balance over 10 and 24 h of recovery. Performance was assessed pre-exercise and at 0, 10, and 24 h of recovery using a battery of tests. Net protein balance tended to improve in PRO (P = 0.064; effect size (ES = 0.61, PRO vs. CHO during overnight recovery. Over 24 h, net balance was enhanced in PRO (P = 0.036 but not in CHO (P = 0.84; ES = 0.69, PRO vs. CHO, which was mediated primarily by a reduction in protein breakdown (PRO < CHO; P < 0.01.

    The iron contents in the hair and blood samples of 37 juvenile athletes who were supplemented with 0, 8 and 16 mg Fe/day, respectively, in the food of ferrous gluconatecontaining chocolate for 3 months were determined before and after the supplementation by INAA, SRXRF and blood analysis. The experimental results showed that after supplementation of the iron-fortified food, the normal ferritin level in the blood of the male athletes was attained and the iron content in the hair was increased with supplementation, but both are not in the positive proportion.

    The iron content in hair and blood for 37 children athletes who were supplemented with 0, 8 and 16 mg Fe/d, respectively, in the form of ferrous gluconate-containing chocolate for 3 months was determined before and after the supplement by INAA, SRXRF and blood analysis. The experimental results indicated that after the supplement of the iron-fortified food, the ferritin level in blood of the male athletes attained to normal and the iron content in hair was increased with the increasing level of supplement, but not in direct proportion. Most of the female athletes had similar results. It is suggested that supplement of 8 mg Fe/d to a child athlete may be adequate

    Full Text Available Abstract Background Smoking is a significant women's health issue. Examining smoking behaviors among occupational groups with a high prevalence of women may reveal the culture of smoking behavior and quit efforts of female smokers. The purpose of this study was to examine how smoking and quitting characteristics (i.e., ever and recent quit attempts among females in the occupation of nursing are similar or different to those of women in the general population. Methods Cross-sectional data from the Tobacco Use Supplement of the Current Population Survey 2006/2007 were used to compare smoking behaviors of nurses (n = 2, 566 to those of non-healthcare professional women (n = 93, 717. Smoking characteristics included years of smoking, number of cigarettes, and time to first cigarette with smoking within the first 30 minutes as an indicator of nicotine dependence. Logistic regression models using replicate weights were used to determine correlates of ever and previous 12 months quit attempts. Results Nurses had a lower smoking prevalence than other women (12.1% vs 16.6%, p p = 0.0002; but not in the previous 12 months (42% vs 43%, p = 0.77. Among those who ever made a quit attempt, nurses who smoked within 30 minutes of waking, were more likely to have made a quit attempt compared to other women (OR = 3.1, 95% CI: 1.9, 5.1. When considering quit attempts within the last 12 months, nurses whose first cigarette was after 30 minutes of waking were less likely to have made a quit attempt compared to other females (OR = 0.69, 95% CI: 0.49, 0.98. There were no other significant differences in ever/recent quitting. Conclusions Smoking prevalence among female nurses was lower than among women who were not in healthcare occupations, as expected. The lack of difference in recent quit efforts among female nurses as compared to other female smokers has not been previously reported. The link between lower level of nicotine dependence, as reflected by the longer

    Full Text Available Objectives. In a previous randomized clinical trial (Falsini et al. (2010, it was shown that short-term Saffron supplementation improves retinal flicker sensitivity in early age-related macular degeneration (AMD. The aim of this study was to evaluate whether the observed functional benefits from Saffron supplementation may extend over a longer follow-up duration. Design. Longitudinal, interventional open-label study. Setting. Outpatient ophthalmology setting. Participants. Twenty-nine early AMD patients (age range: 55–85 years with a baseline visual acuity >0.3. Intervention. Saffron oral supplementation (20 mg/day over an average period of treatment of 14 (±2 months. Measurements. Clinical examination and focal-electroretinogram-(fERG- derived macular (18° flicker sensitivity estimate (Falsini et al. (2010 every three months over a followup of 14 (±2 months. Retinal sensitivity, the reciprocal value of the estimated fERG amplitude threshold, was the main outcome measure. Results. After three months of supplementation, mean fERG sensitivity improved by 0.3 log units compared to baseline values (P<0.01, and mean visual acuity improved by two Snellen lines compared to baseline values (0.75 to 0.9, P<0.01. These changes remained stable over the follow-up period. Conclusion. These results indicate that in early AMD Saffron supplementation induces macular function improvements from baseline that are extended over a long-term followup.

    Full Text Available Background Formulation of herbs into dosage forms promotes their marketing and usage. However, if these herbal products are being taken in an unhealthy trend, they may pose risks to consumers. Aims The present study aimed to investigate herbal product consumption trends (n=550 among adults in the main cities of Malaysia. Methods A questionnaire-based, six-week cross-sectional study was conducted. Respondents were randomly selected in Shah Alam, Klang, Subang, and Kuala Lumpur. Descriptive statistics were used for data analysis and Chi-square test was applied where appropriate. Results Out of the 550 survey instruments distributed, 453(82.4 per cent responded. The prevalence rate of herbal products use among the adult population in the past 12 months was 71.5 per cent. Regarding the consumption profile; the consumers were mostly female (73.4 per cent, age 25–44 (72.8, and educated at tertiary level (74.8 per cent. The majority of respondents perceived that herbal products helped reduce severity of illness and improve health related quality of life, while (16.4 per cent consumed the herbal products for the treatment of menstrual problem, 71.7 per cent without the recommendation of health care professionals and 85.0 per cent of them purchased through over-the-counter retail sales. The herbal products most commonly consume were Labisia pumila (Kacip Fatimah (32.4 per cent, Camellia sinensis (Green Tea (32.1 per cent, Panax ginseng (Ginseng (23.8 per cent, and Eurycoma longifolia (Tongkat Ali (22.5 per cent. Conclusion This study highlights an unhealthy trend in self-prescription of herbal product consumption without healthcare professionals’ recommendation. Hence, there is an urgent need for healthcare professionals to monitor herbal product consumption.

    Food insecurity is negatively associated with US children's dietary intake and health. The Supplemental Nutrition Assistance Program-Education (SNAP-Ed) aims to alleviate food insecurity by offering nutrition, budgeting, and healthy lifestyle education to low-income individuals and families. The objective of this study was to evaluate the long-term impact of the Indiana SNAP-Ed on food security among households with children. A randomized, controlled, parallel study design with SNAP-Ed as an intervention was carried out during a 4- to 10-wk intervention period. Intervention group participants received the first 4 Indiana SNAP-Ed curriculum lessons. Study participants (n = 575) were adults aged ≥18 y from low-income Indiana households with ≥1 child living in the household. Both treatment groups completed an assessment before and after the intervention period and 1 y after recruitment. The 18-item US Household Food Security Survey Module was used to classify the primary outcomes of food security for the household and adults and children in the household. A linear mixed model was used to compare intervention with control group effects over time on food security. Mean ± SEM changes in household food security score and food security score among household adults from baseline to 1-y follow-up were 1.2 ± 0.4 and 0.9 ± 0.3 units lower, respectively, in the intervention group than in the control group (P security score from baseline to 1-y follow-up among household children was not significantly different in the intervention group compared with the control group. SNAP-Ed improved food security over a longitudinal time frame among low-income Indiana households with children in this study. SNAP-Ed may be a successful intervention to improve food security. © 2016 American Society for Nutrition.

    Full Text Available Abstract Background Owing to the mechanics of anti-doping regulation via the World Anti-Doping Agency's Prohibited List, nutritional supplement use received little attention in comparison to the prevalence of doping. The aims of this study were to investigate supplement use, identify groups of athletes with high levels of supplement use and the prevalence of concomitant use of supplements. Methods Survey data from 847 high-performing athletes in the UK were analysed using descriptive statistics. The survey, conducted by UK Sport, consisted of questions regarding knowledge of the prohibited substances, testing procedure, nutritional supplement use and perceptions of the doping problem. The proportion of supplement users and the relative use of each supplement were compared by age, gender and professional status. Results Among 874 high-performing athletes in the UK sample, 58.8% of them reported the use of at least one nutritional supplement. Among supplement users, 82.6% used more than one and 11.5% reported use of more than five nutritional supplements. Of the 9 supplements listed, multivitamins (72.6% and vitamin C (70.7% were used most, followed by creatine (36.1%, whey protein (31.7%, echinacea (30.9%, iron (29.9% and caffeine (23.7%. Less than 11% reported the use of magnesium or ginseng. Creatine use was typically associated with males regardless of status and across all ages, whereas iron was characteristically used by females. A 'typical' supplement user is male, between 24 and 29 years of age, involved in professional sport and using a combination of supplements. Male professional players between age 30 and 34 years, and female non-professional athletes between 24 and 29 years of age also represented a considerable proportion of supplement users. Athletes older than 40 years of age were practically non-users. Concomitant use of supplements is characteristic of male users more than females. Conclusion As supplement use has been previously

    Despite Australia's sunny climate, low vitamin D levels are increasingly prevalent. Sun exposure is limited by long working hours, an increase in time spent indoors, and sun protection practices, and there is limited dietary vitamin D fortification. While the importance of vitamin D for bone mineralization is well known, its role as a protective agent against chronic diseases, such as type 2 diabetes and cardiovascular disease, is less understood. Observational and limited intervention studies suggest that vitamin D might improve insulin sensitivity and secretion, mainly via its anti-inflammatory properties, thereby decreasing the risk of development and progression of type 2 diabetes. The primary aim of this trial is to investigate whether improved plasma concentrations of 25-hydroxyvitamin D (25(OH)D), obtained through vitamin D supplementation, will increase insulin sensitivity and insulin secretion. A secondary aim is to determine whether these relationships are mediated by a reduction in underlying subclinical inflammation associated with obesity. Fifty overweight but otherwise healthy nondiabetic adults between 18 and 60 years old, with low vitamin D levels (25(OH)D daily, while the placebo group will receive apparently identical capsules, both for a period of 16 weeks. All measurements will be repeated at follow-up, with the primary outcome measure expressed as a change from baseline in insulin sensitivity and secretion for the intervention group compared with the placebo group. Secondary outcome measures will compare changes in anthropometry, cardiovascular risk factors, and inflammatory markers. The trial will provide much needed clinical evidence on the impact of vitamin D supplementation on insulin resistance and secretion and its underlying mechanisms, which are relevant for the prevention and management of type 2 diabetes.

    Pseudomeningoceles are common complications after posterior fossa and intradural spinal surgery and are often asymptomatic. Management guidelines are lacking, and anecdotally, we have encountered radically different suggested treatments varying from observation to immediate surgical intervention. The goal of this study was to determine the prevailing opinions among neurosurgeons on the management of this condition. Neurosurgeons from around the world were invited via an International Society for Pediatric Neurosurgery (ISPN) and Neurosurgery ListServ e-blast to participate in a 33-question survey on the management of pseudomeningoceles, presented as simulated scenarios after posterior fossa and spinal intradural surgery. Two hundred forty-one responses were obtained. Pseudomeningoceles after posterior fossa tumor resection, in the absence of hydrocephalus, were typically managed nonoperatively for 7 to 14 days before re-exploration. Only 0.5 % of the surgeons would offer upfront repair of the pseudomeningocele. In the presence of hydrocephalus, 48 % of the neurosurgeons intervene initially with cerebrospinal fluid (CSF) diversion and would change therapy if the lesion did not resolve in 2 to 4 days. Ninety percent of the surgeons manage spinal pseudomeningoceles nonoperatively for 7-14 days before re-exploration is considered. The most common steps taken to prevent pseudomeningoceles are watertight closure, tissue glues, and duroplasty. The present zeitgeist suggests that, in the absence of hydrocephalus, initial observation is appropriate for cranial and spinal pseudomeningoceles. Operative revision should be reserved for failure of conservative treatment. If hydrocephalus is present, consideration should be made for CSF diversion. This study may serve as a guideline regarding acceptable management.

    Little is known about the changes in prevalence of dietary supplement use in pregnancy, postpartum, and in a comparison group of nonpregnant women. We conducted a secondary analysis of the Infant Feeding Practices II study. The purpose of this study is to report the prevalence of herbal or botanical and nonvitamin, nonmineral dietary supplement use by US women with respect to demographic, behavioral, and health factors. We compared pregnant and postpartum women to a comparison group of nonpregnant women who had not given birth in the past 12 months. Our main outcome was the prevalence of dietary supplements. Multiple logistic regression models were used to examine factors associated with herbal or botanical and nonvitamin, nonmineral dietary supplement use during reproductive age, pregnancy, and postpartum. The total sample included 1444 women assessed during the prenatal period, 1422 from the postpartum period, and 1517 women in a comparison group. In terms of herb or botanical use, 15% of the prenatal group, 16% of the postpartum group, and 22% of the comparison group reported using herbs or botanicals. The most frequently used nonvitamin, nonmineral supplement was omega-3 fatty acid. Among the total prenatal group and comparison group, women eating 5 or more servings of fruits or vegetables were less likely to report using herbs or botanicals. Women in the comparison group self-identifying as black were 4 times as likely to report using herbs or botanicals compared to participants self-identifying as white. In addition, women identifying as a race other than white were almost twice as likely to report herb or botanical use across all study groups. This is one of the rare studies that shows the changing prevalence of herbs or botanicals and nonvitamin, nonmineral dietary supplement use in women in the reproductive stage of their lives. © 2016 by the American College of Nurse-Midwives.

    Postoperative hypocalcemia is the most common complication after total thyroidectomy. Postoperative parathyroid hormone (PTH) measurement is one of the methods to detect or prevent postoperative hypocalcemia. Prophylactic oral calcium supplementation is another method to prevent early postoperative hypocalcemia. The aim of this study is to detect the accurate timing of PTH and evaluate efficacy of routine oral calcium supplementation for postoperative hypocalcemia. A total of 106 patients were performed total thyroidectomy. Rotuine oral calcium supplementation was given to group 1 and no treatment to group 2 according to randomization. Serum calcium and PTH level of patients in group 2 at postoperative 6, 12 and 24 h and patients in both groups at postoperative day 7 were evaluated. Patients were compared according to age, sex, operation findings, serum calcium and PTH levels and symptomatic hypocalcemia. Half of the patients (50%) were in group 1. Most of the patients were female (83%). The most common etiology of thyroid disease was multinodular goiter (64.1%). Oral calcium supplementation was given to 18 (33.9%) patients in group 2. Symptomatic hypocalcemia for group 1 and 2 was found to be 1.9 and 33.9% respectively (p hypocalcemia. Prophylactic oral calcium supplementation therapy can prevent early post-thyroidectomy hypocalcemia with advantages of being cost effective and safe. Copyright © 2016 IJS Publishing Group Ltd.

    Purpose: To determine whether zinc supplementation can accelerate the healing of mucositis and dermatitis after radiotherapy. Methods and Materials: In this double-blind study, patients were placed into two randomized groups (experimental and control) of 50 patients each. The groups were homogeneous with respect to medical history, tumor characteristics, and therapeutic details. The experimental group received a standard dose of a zinc supplement, and the control group was given a placebo. Results: Patients in the control group developed Grade 2 mucositis and dermatitis earlier and sooner than patients in the experimental group. There was also a significant difference in the development of Grade 3 mucositis and dermatitis between the two groups. Patients in the experimental group were found to have milder mucositis and dermatitis. Zinc supplementation did not show much benefit in those patients receiving concurrent chemotherapy or make a substantial impact on weight changes. Conclusions: Zinc supplementation used in conjunction with radiotherapy could postpone the development of severe mucositis and dermatitis for patients with cancers of the head and neck. Zinc supplementation can also alleviate the degree of mucositis and dermatitis. The impact of zinc on tumor growth and patient survival is under further investigation

    Full Text Available An extrajudicial accounting survey can be required by the party or parties who set the objectives the chartered accountant should meet, representing an efficient highly specialized assistance tool for any business which wants to be protected from risks. The extrajudicial accounting survey has a much larger and more complex span than the judicial one, aiming at different issues: economic, patrimonial, managerial, financial, fiscal, information ones, surpassing most of the times the strict frame of financial and accounting information and services. The aim of the paper is to emphasize the deeply applicative character of the extrajuridical accounting survey in clarifying varying aspects that occur in a company‘s activity and that affect the decision making. The article focuses on the presentation of a sample extrajuridical accounting survey report with remarks, which, both in form and content, can become a source of inspiration both for theoretical debates and in the practical activity. In the international practice, the extrajudicial accounting surveys are used both for making important economic decisions, and for the fair information of all those who use accounting information, for certifying certain calculations or information, for rationalizing information flows etc.

    Quality of life is a complex construct that affects the overall life satisfaction, emotional well-being, and functioning of individuals. The aim of our study was to assess the quality of life of dental students at one U.S. dental school, using the World Health Organization Quality of Life (WHOQOL)-BREF, a multi-dimensional, cross-cultural, validated, and reliable survey instrument. Of the 1,437 students invited to participate, 401 students responded, but 17 were excluded because of missing data. The final sample consisted of 384 students for an overall response rate of 27%: response rates by year were first year 32.6%, second year 16.9%, third year 26.6%, and fourth year 24.0%. The results showed that the responding students rated their overall quality of life as good. The Physical Health domain had the highest mean score, while the Psychological domain had the lowest. Females reported higher quality of life than males in the Social Relationships domain. Single students were found to have a lower perceived quality of life than married students. Older students were found to have lower perceived quality of life in the Physical Health and Environment domains. Physical Health domain scores were significantly higher for fourth-year than first-year respondents, while Psychological domain scores were significantly lower for third-year than first-year respondents. Further research is needed to explore the effect of dental school on the quality of life of dental students. Targeted programs to impact students' quality of life at various points in the curriculum may be beneficial.

    Creatine is considered an effective nutritional ergogenic aid to enhance exercise performance. In spite of the publication of several reviews in the last decade on the topic of exercise performance/sports and creatine there is a need for an update related to the military given the lack of information in this area. The aim of this study was to critically assess original research addressing the use of creatine supplements in the military. A search of the electronic databases PubMed and SPORTDiscus, for the following key words: military personnel, trainees, recruit, soldier, physical fitness, physical conditioning, creatine supplementation, creatine ingestion, nutritional supplements to identify surveys and randomised clinical trials from journal articles and technical reports investigating the effect of creatine supplementation on military populations. Thirty-three out of 90 articles examined the use of creatine as a dietary supplement in military personnel. Twenty-one studies were finally selected on the basis of stated inclusion criteria for military surveys and randomised clinical trials. Most of the surveys (15/17) in the military indicate a high popularity of creatine (average 27%) among supplement users. In contrast, in most of the exercise protocols used (6/9) during randomised clinical trials creatine has produced a non-significant performance-enhancing effect. Creatine is one of the most widely used supplemental compounds in the military. It is not considered a doping infraction or related to any adverse health effects but its long-term usage needs further investigation. Experimental research suggests that creatine supplementation does not enhance physical performance in the military. However, limitations in creatine dosage, military fitness testing and sample group selection might have underestimated the ergogenic properties of creatine. Recent studies also indicate positive effects on various aspects of total force fitness such as cognitive

Most nutritional supplements (46% were initiated when early/intermediate AMD was confirmed, although 18% were initiated on confirmation of neovascular AMD. Clinical studies were well known: 90% were aware of AREDS, with 88% aware of AREDS1 and 36% aware of the, as-yet-unpublished, AREDS2 studies. Respondents considered lutein, zeaxanthin, zinc, omega-3, and vitamins to be the most important components of nutritional supplements, with the results of AREDS2 already having been taken into consideration by many. Ophthalmologists anticipate more scientific studies as well as improved product quality but identify cost as a barrier to wider uptake.Conclusion: Micronutrition is now part of the routine management of AMD for many ophthalmologists. Ophthalmologists choosing to use nutritional supplements are well-informed regarding current scientific studies. Keywords: age-related macular degeneration, micronutrition, nutritional

    Although dietary supplement use is believed to improve health status, the efficacy and safety of its use remains controversial. This study aimed to investigate the contribution of consumption of vitamin and mineral supplements (VMS) to the total micronutrient intake. Study participants ( n = 586) were selected from the ongoing prospective cohort study of the Korean population, and baseline information on current use of dietary supplements, types of supplements, frequency of use, dosage, duration, and brand name was collected. Dietary information was assessed using a 146-item semi-quantitative food frequency questionnaire. Approximately one-fourth of the participants were categorized as VMS users. The proportion of VMS use was significantly higher in women ( p = 0.02), older participants ( p = 0.002), and those with a higher income level ( p = 0.03) than in non-users. All vitamin and mineral intakes of both groups met the recommended nutrient intake levels by food consumption alone, except for riboflavin, calcium, and magnesium. Approximately 0.7-3.4% of the VMS users had nutrient intake levels that exceeded the tolerable upper intake levels for vitamin A, E, C, iron, and iodine. Excessive use of VMS can lead to an increased risk for adverse health effects. The results of this study provide useful baseline data for establishing guidelines for the appropriate consumption and adequate intake levels of VMS.

    Full Text Available Although dietary supplement use is believed to improve health status, the efficacy and safety of its use remains controversial. This study aimed to investigate the contribution of consumption of vitamin and mineral supplements (VMS to the total micronutrient intake. Study participants (n = 586 were selected from the ongoing prospective cohort study of the Korean population, and baseline information on current use of dietary supplements, types of supplements, frequency of use, dosage, duration, and brand name was collected. Dietary information was assessed using a 146-item semi-quantitative food frequency questionnaire. Approximately one-fourth of the participants were categorized as VMS users. The proportion of VMS use was significantly higher in women (p = 0.02, older participants (p = 0.002, and those with a higher income level (p = 0.03 than in non-users. All vitamin and mineral intakes of both groups met the recommended nutrient intake levels by food consumption alone, except for riboflavin, calcium, and magnesium. Approximately 0.7–3.4% of the VMS users had nutrient intake levels that exceeded the tolerable upper intake levels for vitamin A, E, C, iron, and iodine. Excessive use of VMS can lead to an increased risk for adverse health effects.

    Full Text Available Abstract Background There have been multiple studies carried out in many countries with regard to the use of nonvitamin, nonmineral (NVNM supplements. These studies have shown that the use of NVNM supplements is on the increase throughout the world, particularly in western countries. The aim of this study was to assess the extent of NVNM supplement use among Turkish university students. Methods The survey was conducted between September and December 2004 at Osmangazi University, a public university located in the west of Turkey. Responses were analysed, using the chi-square (x2 test, t test and percent (% ratios, according to gender and consumers. Differences were considered significant for p ≤ 0.05. Results Of 2253 students attending the university, 1871 participated in the survey (909 men and 962 women. Overall, the prevalence of NVNM supplement use was 16.5% (16.6% in men and 16.3% in women, p The three most commonly given reasons for use were 'improvement of energy and vitality (78.6%', 'promotion of weight loss (71.1%', followed by 'enhancement of athletic performance (64.3%'. Twenty-six of the 308 reported NVNM users (26/308, 8.4% reported having experienced an adverse reaction. Television (76.3%, magazines/newspapers (41.5% and internet websites (37.3% were the most frequently used sources for obtaining information about NVNM supplements. The three most frequently used NVNM supplements were echinacea, ginseng, and gingko biloba (38.6%, 36.4%, and 32.8%, respectively. Nutritional scores were higher in NVNM supplement users than in non-users (66.510.8 vs. 62.712.7 (p Conclusion The results indicate that the prevalence of NVNM supplement use is relatively modest among Turkish university students and more information is needed on why people use particular NVNM supplements.

    Some intervention studies have shown that quercetin supplementation can regulate certain biomarkers, but it is not clear how the doses given relate to dietary quercetin (e.g. from onion). We conducted a two-period, two-sequence crossover study to compare the bioavailability of quercetin when administered in the form of a fresh red onion meal (naturally glycosylated quercetin) or dietary supplement (aglycone quercetin) under fasting conditions. Six healthy, non-smoking, adult males with BMI 22.7 ± 4.0 kg m(-2) and age 35.3 ± 12.3 y were grouped to take the two study meals in random order. In each of the 2 study periods, one serving of onion soup (made from 100 g fresh red onion, providing 156.3 ± 3.4 μmol (47 mg) quercetin) or a single dose of a quercetin dihydrate tablet (1800 ± 150 μmol (544 mg) of quercetin) were administered following 3 d washout. Urine samples were collected up to 24 h, and after enzyme deconjugation, quercetin was quantified by LC-MS. The 24 h urinary excretion of quercetin (1.69 ± 0.79 μmol) from red onion in soup was not significantly different to that (1.17 ± 0.44 μmol) for the quercetin supplement tablet (P = 0.065, paired t-test). This means that, in practice, 166 mg of quercetin supplement would be comparable to about 10 mg of quercetin aglycone equivalents from onion. These data allow intervention studies on quercetin giving either food or supplements to be more effectively compared.

    Sterilization of medical aid articles (e.g. catheters, one-way syringes) with ionizing radiation is a successful practice in many countries. During recent years, the results from numerous experiments of radiosterillization of pharmaceuticals and adjuvants have likewise been published. Experience has shown that radiation treatment, in many cases, is leading to transformations of the irradiated substances. In the present part IX of the bibliographic study on the influence of radiation treatment on pharmaceuticals and adjuvants the results of experiments on ca. 80 substances from 36 different sources have been evaluated. In all parts of the study results of about 560 experiments on 360 substances from 176 different sources are present. (orig.)

    Intervention studies do not account for high within-individual variation potentially compromising the magnitude of an effect. Repeat administration of a treatment allows quantification of individual responses and determination of the consistency of responses. We determined the consistency of metabolic and exercise responses following repeated administration of sodium bicarbonate (SB). 15 physically active males (age 25±4 y; body mass 76.0±7.3 kg; height 1.77±0.05 m) completed six cycling capacity tests at 110% of maximum power output (CCT110%) following ingestion of either 0.3 g∙kg-1BM of SB (4 trials) or placebo (PL, 2 trials). Blood pH, bicarbonate, base excess and lactate were determined at baseline, pre-exercise, post-exercise and 5-min post-exercise. Total work done (TWD) was recorded as the exercise outcome. SB supplementation increased blood pH, bicarbonate and base excess prior to every trial (all p ≤ 0.001); absolute changes in pH, bicarbonate and base excess from baseline to pre-exercise were similar in all SB trials (all p > 0.05). Blood lactate was elevated following exercise in all trials (p ≤ 0.001), and was higher in some, but not all, SB trials compared to PL. TWD was not significantly improved with SB vs. PL in any trial (SB1: +3.6%; SB2 +0.3%; SB3: +2.1%; SB4: +6.7%; all p > 0.05), although magnitude-based inferences suggested a 93% likely improvement in SB4. Individual analysis showed ten participants improved in at least one SB trial above the normal variation of the test although five improved in none. The mechanism for improved exercise with SB was consistently in place prior to exercise, although this only resulted in a likely improvement in one trial. SB does not consistently improve high intensity cycling capacity, with results suggesting that caution should be taken when interpreting the results from single trials as to the efficacy of SB supplementation.

  17. Reactivity of Chromium(III) Nutritional Supplements in Biological Media: An X-Ray Absorption Spectroscopic Study

    2009-05-22

    Chromium(III) nutritional supplements are widely used due to their purported ability to enhance glucose metabolism, despite growing evidence on low activity and the potential genotoxicity of these compounds. Reactivities of Cr(III) complexes used in nutritional formulations, including [Cr3O(OCOEt)6(OH2)3]+ (A), [Cr(pic)3] (pic) = 2-pyridinecarboxylato(-) (B), and trans-[CrCl2(OH2)4]+ (CrCl3 {center_dot} 6H2O; C), in a range of natural and simulated biological media (artificial digestion systems, blood and its components, cell culture media, and intact L6 rat skeletal muscle cells) were studied by X-ray absorption near-edge structure (XANES) spectroscopy. The XANES spectroscopic data were processed by multiple linear-regression analyses with the use of a library of model Cr(III) compounds, and the results were corroborated by the results of X-ray absorption fine structure spectroscopy and electrospray mass spectrometry. Complexes A and B underwent extensive ligand-exchange reactions under conditions of combined gastric and intestinal digestion (in the presence of a semisynthetic meal, 3 h at 310 K), as well as in blood serum and in a cell culture medium (1-24 h at 310 K), with the formation of Cr(III) complexes with hydroxo and amino acid/protein ligands. Reactions of compounds A-C with cultured muscle cells led to similar ligand-exchange products, with at least part of Cr(III) bound to the surface of the cells. The reactions of B with serum greatly enhanced its propensity to be converted to Cr(VI) by biological oxidants (H2O2 or glucose oxidase system), which is proposed to be a major cause of both the insulin-enhancing activity and toxicity of Cr(III) compounds (Mulyani, I.; Levina, A.; Lay, P. A. Angew. Chem. Int. Ed. 2004, 43, 4504-4507). This finding enhances the current concern over the safety of consumption of large doses of Cr(III) supplements, particularly [Cr(pic)3].

    Diabetes mellitus is characterized by hyperglycemia and associated with aberrations in the metabolism of carbohydrate, protein, and lipid that result in development of secondary complications. Extensive studies have indicated that nutritional therapy plays a pivotal role in the controlling or postponing of development of these secondary complications. Several functional foods have been shown to possess hypoglycemic and hypolipidemic properties. Flax seed (FS) is a functional food that is rich in omega 3 fatty acids and antioxidants and is low in carbohydrates. In exploratory studies, FS was incorporated in recipes, which resulted in a reduction in the glycemic index of the food items. These observations prompted us to investigate the efficacy of FS supplementation in type 2 diabetics (n = 29). Subjects were assigned to the experimental (n = 18) or the control group (n = 11) on the basis of their desire to participate in the study. The experimental group's diet was supplemented daily with 10 g of FS powder for a period of 1 month. The control group received no supplementation or placebo. During the study, diet and drug intake of the subjects remained unaltered. The efficacy of supplementation with FS was evaluated through a battery of clinico-biochemical parameters. Supplementation with FS reduced fasting blood glucose by 19.7% and glycated hemoglobin by 15.6%. A favorable reduction in total cholesterol (14.3%), triglycerides (17.5%), low-density lipoprotein cholesterol (21.8%), and apolipoprotein B and an increase in high-density lipoprotein cholesterol (11.9%) were also noticed. These observations suggest the therapeutic potential of FS in the management of diabetes mellitus.

    While there are many reports of studies that fed arachidonic acid (AA) to animals, there are very few reports of AA feeding to humans under controlled conditions. This 130-d study was conceived as a controlled, symmetrical crossover design with healthy, adult male volunteers. They lived in the metabolic research unit (MRU) of the Western Human Nutrition Research (WHNRC) for the entire study. All food was prepared by the WHNRC kitchen. The basal (low-AA) diet consisted of natural foods (30 en% fat, 15 en% protein, and 55 en% carbohydrate), containing 210 mg/d of AA, and met the recommended daily allowance for all nutrients. The high-AA (intervention) diet was similar except that 1.5 g/d of AA in the form of a triglyceride containing 50% AA replaced an equal amount of high-oleic safflower oil in the basal diet. The subjects (ages 20 to 39) were within -10 to +20% of ideal body weight, nonsmoking, and not allowed alcohol in the MRU. Their exercise level was constant, and their body weights were maintained within 2% of entry level. Subjects were initially fed the low-AA diet for 15 d. On day 16, half of the subjects (group A) wee placed on the high-AA diet, and the other group (B) remained on the low-AA diets. On day 65, the two groups switched diets. On day 115, group B returned to the low-AA diet. This design, assuming no carryover effect, allowed us to merge the data from the two groups, with the data comparison days being 65 (low-AA) and 115 (high-AA) for group B and 130 (low-AA) and 65 (high-AA) for group A. The main indices studied were the fatty acid composition of the plasma, red blood cells, platelets, and adipose tissue; in vitro platelet aggregation, bleeding times, clotting factors; immune response as measured by delayed hypersensitivity skin tests, cellular proliferation of peripheral blood mononuclear cells in response to various mitogens and antigens, natural killer cell activity, and response to measles/mumps/rubella and influenza vaccines; the

Using the physiological reaction of organisms, this system settled the problem in food supply, O2 and water recycle, the regeneration and utilization of CO2 and life residues, thus guarantee the spacemen the health, safety and efficient work when they are far from earth and arrived the space where human is difficult to life in. Azolla as a plant that possesses high growing speed, short growing cycle, high photosynthesis and O2-releasing capacity, and can be artificially grow in multi-layer facilities, it is hopeful to be an important biological part in CELSS for it's the function in O2 production and to be a part of fresh vegetable as well as CO2 absorption. This paper described the study in Azolla as a plant for supplementary O2 supply in future space station flight. The "Azolla-dog" controlling tight system was firstly established in order to determine the regulation of O2-CO2 variation and balance using different weights of dogs with different Azolla growing areas. The further studies included the development of air-tight cabinets where "Azolla-human" airtight experiments were conducted, and the relationship between Azolla-growing area and O2 requirement by human was analyzed. Based on these works, the further experiment on supplementary O2-supply of Azolla-human system was conducted in demonstration cabin for environmental controlling and life security. The O2-supplying amount of Azolla was further gained, and it will provide the experimental basis to probe optimum condition to grow Azolla in space and human-machine combining experiment, also to lay a basis for Azolla as a biological part to enter

    Chronic kidney disease (CKD) patients develop metabolic acidosis when approaching stages 3 and 4, a period in which accelerated atherogenesis may ensue. Studies in vitro show that low pH may increase low-density lipoprotein (LDL) oxidation, suggesting a role for chronic metabolic acidosis in atherosclerosis. The present study attempted to evaluate the effects of conservative care using oral sodium bicarbonate (NaHCO 3 ) supplementation on the electronegative LDL [LDL(-)], a minimally oxidized LDL, plasma levels in CKD patients. Thirty-one CKD patients were followed by a multidisciplinary team during 15 months of care in which 1.0 mmol/kg/day oral NaHCO 3 supplementation was first given in the third month. Blood samples were collected 3 months before the initiation of oral NaHCO 3 supplementation (T1), at the time of the beginning of supplementation (T2), and thereafter, each 4 months (T3, T4 and T5) until month 15 of care. Blood parameters and LDL(-) were measured from these collections. After 12 months of conservative care, creatinine clearance (MDRD) was kept stable, and serum bicarbonate (HCO 3 - ) increased from 20.5 ± 2.9 to 22.6 ± 1.1 mM ( p < 0.003). LDL(-) plasma levels declined from 4.5 ± 3.3 to 2.1 ± 0.9 U/L ( p < 0.007) after reaching mean serum HCO 3 - levels of 22.6 ± 1.1 mM. Conservative care using oral NaHCO 3 supplementation was able to stabilize renal function and decrease serum levels of LDL(-), a modified proatherogenic lipoprotein, only when mean serum HCO 3 - levels approached 22 mM. This study constitutes evidence that alkali therapy, in addition to its beneficial effect on renal disease progression, might serve as a preventive strategy to attenuate atherogenesis in CKD patients.

    Evidence Based Medicine (EBM) is increasingly being applied to inform clinical decision-making in orthopaedic surgery. Despite the promotion of EBM in Orthopaedic Surgery, the adoption of results from high quality clinical research seems highly unpredictable and does not appear to be driven strictly by randomized trial data. The objective of this study was to pilot a survey to determine if we could identify surgeon opinions on the characteristics of research studies that are perceived as being most likely to influence clinical decision-making among orthopaedic surgeons in Canada. A 28-question electronic survey was distributed to active members of the Canadian Orthopaedic Association (COA) over a period of 11 weeks. The questionnaire sought to analyze the influence of both extrinsic and intrinsic characteristics of research studies and their potential to influence practice patterns. Extrinsic factors included the perceived journal quality and investigator profiles, economic impact, peer/patient/industry influence and individual surgeon residency/fellowship training experiences. Intrinsic factors included study design, sample size, and outcomes reported. Descriptive statistics are provided. Of the 109 members of the COA who opened the survey, 95 (87%) completed the survey in its entirety. The overall response rate was 11% (95/841). Surgeons achieved consensus on the influence of three key designs on their practices: 1) randomized controlled trials 94 (99%), 2) meta-analysis 83 (87%), and 3) systematic reviews 81 (85%). Sixty-seven percent of surgeons agreed that studies with sample sizes of 101-500 or more were more likely to influence clinical practice than smaller studies (n = design influencing adoption included 1) reputation of the investigators (99%) and 2) perceived quality of the journal (75%). Although study design and sample size (i.e. minimum of 100 patients) have some influence on clinical decision making, surgeon respondents are equally influenced

    Dietary supplement use is endemic in young athletes; however, it is unclear if their choices are congruent with their motivation for supplementation and the established benefits of the dietary supplements. The aim of this study was to evaluate the relationships between dietary supplement use and self-reported rationale in young athletes. Canadian athletes (n = 567; 11-25 years; 76% club or provincial level, 24% national or higher) completed a questionnaire designed to assess supplementation patterns and motivation for supplementation. Chi square tests examined associations between dietary supplements and self-reported rationale for use. Vitamin and mineral supplements, including vitamin-enriched water, were associated with several health- and performance- related reasons (p performance reasons, as were performance foods (protein powder, sport bars, sport gels, etc.). Plant extracts and fatty acids were primarily associated with health reasons, particularly immune support (p performance rationales and supplementation for common ergogenic aids, however, less so for vitamin and mineral supplements, vitamin-enriched water, and plant extracts. Incongruences were found between fatty acids, protein supplements, vitamin and mineral supplements, vitamin-enriched water, and plant extracts and health motivators for supplementation. Educational interventions are essential to ensure young athletes are using dietary supplements safely and effectively.

    Worldwide we are facing a serious demographic challenge due to the dramatic growth of the population over 60 years. It is expected that the proportion of this population will nearly double from 12 to 22 %, between 2015 and 2050. This demographic shift comes with major health and socio-economic concerns. Nutrition is a fundamental determinant of both health and disease and its role in extending a healthy lifespan is the object of considerable research. Notably, malnutrition is one of the main threats to health and quality of life among the elderly. Therefore, knowledge about nutritional status among the elderly is essential for the promotion and maintenance of healthy ageing and to support the development of health protection policies and equity in elderly health care. This is a nationwide nutrition survey of the Portuguese population over 65 years old, with data collection through face-to-face interviews. A representative and random sample of community dwelling elderly and nursing homes residents will be obtained by multistage sampling stratified per main Portuguese regions, sex and age groups. Minimum sample size was estimated to be 2077 elderly (979 in the community and 1098 in nursing homes). Data will be collected on food habits and eating patterns, nutritional status, food insecurity, lifestyle, self-rated general health status and self-reported diseases, functionality, loneliness, cognitive function, emotional status and demographic and socio-economic characterization. This is the first national survey to evaluate the prevalence of nutritional risk and malnutrition of the Portuguese population above 65 years old, including those living in nursing homes. It will allow the identification of population subgroups of elderly with increased odds of malnutrition and nutritional risk. In addition, this survey will contribute to the identification of psychosocial and clinical predictors of malnutrition among elderly, which is an important risk factor for other

    Full Text Available Abstract Background Osteoarthritis (OA is a slowly destructive process that may be influenced by a nutritional mineral balance in the body. Methods This small, double blind, placebo controlled pilot study investigated the impact of treatment with a natural multi-mineral supplement from seaweed (Aquamin on 6 minute walking distance (6 MWD, range of motion (ROM, and pain and joint mobility measured by the Western Ontario and McMaster Universities (WOMAC Osteoarthritis Index in subjects with moderate to severe OA of the knee during gradual withdrawal of non-steroidal anti-inflammatory drugs (NSAIDs that were being used daily for pain management. Subjects (n = 29 with moderate to severe OA of the knee were randomised to receive either Aquamin (2400 mg/d or Placebo for up to 12 weeks. Results Of the 29 subjects initially randomized, only 22 subjects proceeded to treatment due to 7 subjects not meeting study selection criteria at baseline. Fourteen subjects completed the study and an ITT analysis (n = 22 of the data showed no significant differences in WOMAC scores however, the data did reveal significant improvements in passive and active extension ROM (0.83° ± 1.54 vs. -1.54° ± 2.43; difference, 5.2° ± 2.2, p = 0.028 and 6 MWD (150 ± 48 ft vs. 12.5 ± 31.5 ft; difference, 136 ± 57 ft, p = 0.03 in the Aquamin group compared to the placebo group; respectively, following a 50% reduction in NSAID use. The treatments were well tolerated and the adverse event profiles were not significantly different between the groups. Conclusion This small preliminary study suggests Aquamin may increase range of motion and walking distances in subjects with OA of the knee and may allow partial withdrawal of NSAIDs over 12 weeks of treatment. Additional research is needed to confirm these preliminary observations. Trial registration NCT00755482

    Full Text Available Although many cancer patients use complementary and alternative medicine, including Agaricus blazei Murill (ABM, safety is not yet well understood. Cancer survivors took 1.8, 3.6, or 5.4 g ABM granulated powder (Kyowa Wellness Co., Ltd., Tokyo, Japan per day orally for 6 months. Adverse events were defined by subjective/objective symptoms and laboratory data according to the National Cancer Institute Common Terminology Criteria for Adverse Events version 3.0 (NCI-CTCAE v3.0. Seventy-eight patients were assessed for safety of ABM (30/24/24 subjects at 1/2/3 packs per day, resp.. Adverse events were observed in 9 patients (12%. Most were digestive in nature such as nausea and diarrhea, and one patient developed a liver dysfunction-related food allergy, drug lymphocyte product. However, none of these adverse events occurred in a dose-dependent manner. This study shows that ABM does not cause problems in most patients within laboratory parameters at the dosages tested over 6 months. This trial supports previous evidence that the ABM product is generally safe, excluding possible allergic reaction.

    To determine the effects of feeding a diet supplemented with fish oil omega-3 fatty acids on carprofen dosage in dogs with osteoarthritis. Randomized, controlled, multisite clinical trial. 131 client-owned dogs with stable chronic osteoarthritis examined at 33 privately owned veterinary hospitals in the United States. In all dogs, the dosage of carprofen was standardized over a 3-week period to approximately 4.4 mg/kg/d (2 mg/lb/d), PO. Dogs were then randomly assigned to receive a food supplemented with fish oil omega-3 fatty acids or a control food with low omega-3 fatty acid content, and 3, 6, 9, and 12 weeks later, investigators made decisions regarding increasing or decreasing the carprofen dosage on the basis of investigator assessments of 5 clinical signs and owner assessments of 15 signs. Linear regression analysis indicated that over the 12-week study period, carprofen dosage decreased significantly faster among dogs fed the supplemented diet than among dogs fed the control diet. The distribution of changes in carprofen dosage for dogs in the control group was significantly different from the distribution of changes in carprofen dosage for dogs in the test group. Results suggested that in dogs with chronic osteoarthritis receiving carprofen because of signs of pain, feeding a diet supplemented with fish oil omega-3 fatty acids may allow for a reduction in carprofen dosage.

    Non-alcoholic fatty liver disease (NAFLD) is usually associated with insulin resistance, central obesity, reduced glucose tolerance, type 2 diabetes mellitus and hypertriacylglycerolaemia. The beneficial effects of resveratrol on metabolic disorders have been shown previously. The aim of this study was to evaluate the effects of resveratrol supplementation on cardiovascular risk factors in patients with NAFLD. In this randomised double-blinded placebo-controlled clinical trial, fifty NAFLD patients were supplemented with either a 500-mg resveratrol capsule or a placebo capsule for 12 weeks. Both groups were advised to follow an energy-balanced diet and physical activity recommendations. resveratrol supplementation reduced alanine aminotransferase (ALT) and hepatic steatosis significantly more than placebo (P0·05). There were no significant changes in blood pressure, insulin resistance markers and TAG in either group (P>0·05). Our data have shown that 12-week supplementation of 500 mg resveratrol does not have any beneficial effect on anthropometric measurements, insulin resistance markers, lipid profile and blood pressure; however, it reduced ALT and hepatic steatosis in patients with NAFLD.

    Introduction Supplementation of Omega-3 fatty acids (n-3FA) in athletes is related to the anti-inflammatory and/or antioxidant effect and consequently its action on all the processes of tissue restoration and adaptation to physical stress. Objective Evaluate the Omega-3 Index (O3Ix) response, in red blood cells, to supplemental EPA + DHA intake in the form of high purity and stable composition gums (G), in elite summer athletes. Method Twenty-four summer sport athletes of both sexes, pertaining to the Olympic Training Center in Spain, were randomized to two groups (2G = 760 or 3G = 1140 mg of n-3 FA in Omegafort OKids, Ferrer Intl.) for 4 months. Five athletes and four training staff volunteers were control group. Results The O3Ix was lower than 8% in 93.1% of all the athletes. The supplementation worked in a dose-dependent manner: 144% for the 3G dose and 135% for the 2G, both p < 0.001, with a 3% significant decrease of Omega-6 FAs. No changes were observed for the control group. Conclusions Supplementation with n-3FA increases the content of EPA DHA in the red blood cells at 4 months in a dose-dependent manner. Athletes with lower basal O3Ix were more prone to increment their levels. The study is registered with Protocol Registration and Results System (ClinicalTrials.gov) number NCT02610270. PMID:28656110

    To assess whether vitamin D supplementation could be associated with a modification of inflammatory markers and bone turnover in HIV-1-infected patients. Patients who participated in an initial survey in 2010 and who were followed in the same department were included in a new study in 2012. Between 2010 and 2012, vitamin D supplementation was offered to patients presenting with hypovitaminosis D as per appropriate guidelines. Clinical examinations were performed, and fasting blood samples were taken for inflammation and bone marker evaluations. Of the 263 patients who participated in the 2010 study, 198 were included in the 2012 study. Hypovitaminosis D was observed in 47% (36/77) of participants supplemented as per appropriate guidelines, in 78% (75/97) of transiently or incompletely supplemented participants, and in 71% (17/24) of non-supplemented participants (mainly because vitamin D levels in 2010 were normal). No significant correlation between vitamin D supplementation and the 2-year inflammation outcome (IL-6 and hsCRP) or C-terminal telopeptide levels was observed. However, a decrease in IL6 levels over the 2 years significantly correlated with reaching a normal vitamin D level (OR=0.89 per+1pg/mL IL6 increase, 95% CI=0.81-0.97, P=0.015). Vitamin D supplementation decreases the risk of hypovitaminosis D but does not decrease the risk of inflammation nor bone turnover, unless normal 25-OH vitamin D levels are reached.

    Phenylketonuria is an inherited disease for which the main treatment is the dietary restriction of the amino acid phenylalanine. The diet has to be initiated in the neonatal period to prevent or reduce mental handicap. However, the diet is very restrictive and unpalatable and can be difficult to follow. A deficiency of the amino acid tyrosine has been suggested as a cause of some of the neuropsychological problems exhibited in phenylketonuria. Therefore, this review aims to assess the efficacy of tyrosine supplementation for phenylketonuria. To assess the effects of tyrosine supplementation alongside or instead of a phenylalanine-restricted diet for people with phenylketonuria, who commenced on diet at diagnosis and either continued on the diet or relaxed the diet later in life. To assess the evidence that tyrosine supplementation alongside, or instead of a phenylalanine-restricted diet improves intelligence, neuropsychological performance, growth and nutritional status, mortality rate and quality of life. We searched the Cochrane Cystic Fibrosis and Genetic Disorders Group's Trials Register which is comprised of references identified from comprehensive electronic database searches, handsearches of relevant journals and abstract books of conference proceedings. Additional studies were identified from handsearches of the Journal of Inherited Metabolic Disease (from inception in 1978 to 1998). The manufacturers of prescribable dietary products used in the treatment of phenylketonuria were also contacted for further references.Date of the most recent search of the Group's Inborn Errors of Metabolism Trials Register: 28 June 2012. All randomised or quasi-randomised trials investigating the use of tyrosine supplementation versus placebo in people with phenylketonuria in addition to, or instead of, a phenylalanine-restricted diet. People treated for maternal phenylketonuria were excluded. Two authors independently assessed the trial eligibility, methodological quality

    Stroke is the leading cause of disability. A need exists for an effective intervention to enhance upper extremity (UE) motor abilities and activities of daily living (ADL) performance. The objectives of this pilot study were to (1) determine the feasibility of adding Interactive Metronome (IM) to an occupational therapy (OT) program; and (2) determine changes in UE impairments, function, quality of life, and perceived physical performance ability and satisfaction using a combined IM + OT regimen compared with OT alone for adults with chronic stroke. This pilot study (n=10) used a 2-group (OT or IM+OT) pretest-posttest design. The intervention involved 60 minutes of IM + OT or OT alone, 3 days a week for 10 weeks. Outcome measures included the UE Fugl-Meyer (impairment), the Arm Motor Ability Test (function), the Box and Block Test (function), Stroke Impact Scale (quality of life), and the Canadian Occupational Performance Measure (perceived performance ability and satisfaction). It was feasible to add IM to OT. The IM+OT group demonstrated decreased impairment and increased quality of life. However, the OT-alone group demonstrated greater gains in function, perceived physical performance ability, and satisfaction. These findings suggest that rhythm and timing training using the IM is a feasible intervention to consider as part of therapy treatment. However, IM may fit best for prefunctional treatment, as it seemed to primarily decrease impairment. It may also serve as a supplement before or after treatment in order to maximize rehabilitation potential. Clinical implications and suggestions for future studies are provided.

    Objectives We examined the use of low (<400 μg/day, including no use) and high folic acid supplement (FAS) dosages (≥1000 μg/day) among pregnant women in Spain, and explored factors associated with the use of these non-recommended dosages. Design Population-based cohort study. Setting Spain. Participants We analysed data from 2332 pregnant women of the INMA study, a prospective mother-child cohort study in Spain. Main outcome measures We assessed usual dietary folate and the use of FAS from preconception to the 3rd month (first period) and from the 4th to the 7th month (second period), using a validated food frequency questionnaire. We used multinomial logistic regression to estimate relative risk ratios (RRRs). Results Over a half of the women used low dosages of FAS in the first and second period while 29% and 17% took high dosages of FAS, respectively. In the first period, tobacco smoking (RRR=1.63), alcohol intake (RRR=1.40), multiparous (RRR=1.44), unplanned pregnancy (RRR=4.20) and previous spontaneous abortion (RRR=0.58, lower use of high FAS dosages among those with previous abortions) were significantly associated with low FAS dosages. Alcohol consumption (RRR=1.42), unplanned pregnancy (RRR=2.66) and previous spontaneous abortion (RRR=0.68) were associated with high dosage use. In the second period, only tobacco smoking was significantly associated with high FAS dosage use (RRR=0.67). Conclusions A high proportion of pregnant women did not reach the recommended dosages of FAS in periconception and a considerable proportion also used FAS dosages ≥1000 μg/day. Action should be planned by the Health Care System and health professionals to improve the appropriate periconceptional use of FAS, taking into consideration the associated factors. PMID:26603248

    2,4-Dinitrophenol (DNP) poses serious health-risks to humans. The aims of this three-stage multidisciplinary project were, for the first time, to assess the risks to the general public from fraudulent sale of or adulteration/contamination with DNP; and to investigate motives, reasons and risk-management among DNP-user bodybuilders and avid exercisers. Using multiple search-engines and guidance for Internet research, online retailers and bodybuilding forums/blogs were systematically explored for availability of DNP, advice offered on DNP use and user profiles. Ninety-eight pre-workout and weight-loss supplements were purchased and analysed for DNP using liquid-chromatography-mass-spectrometry. Psychosocial variables were captured in an international sample of 35 DNP users (26.06 ± 6.10 years, 94.3 % male) with an anonymous, semi-qualitative self-reported survey. Although an industrial chemical, evidence from the Internet showed that DNP is sold 'as is', in capsules or tablets to suit human consumption, and is used 'uncut'. Analytical results confirmed that DNP is not on the supplement market disguised under fictitious supplement names, but infrequently was present as contaminant in some supplements (14/98) at low concentration (<100mcg/kg). Users make conscious and 'informed' decisions about DNP; are well-prepared for the side-effects and show nonchalant attitude toward self-experimentation with DNP. Steps are often taken to ensure that DNP is genuine. Personal experience with performance- and appearance enhancing substances appears to be a gateway to DNP. Advice on DNP and experiences are shared online. The significant discrepancy between the normative perception and the actual visibility suggests that DNP use is-contrary to the Internet accounts-a highly concealed and lonesome activity in real life. Positive experiences with the expected weight-loss prevail over the negative experiences from side effects (all but two users considered using DNP again) and help

    We developed a quantitative method for attaining a representative sample during sampling survey of RI waste. Considering a source, process, and type of RI waste, the method computes the number of sample, confidence interval, variance, and coefficient of variance. We also systematize the method of sampling survey logically and quantitatively. The result of this study can be applied to sampling survey of low- and intermediate-level waste generated from nuclear power plant during the transfer process to disposal facility.

    Evidence is lacking for multi-ingredient herbal supplements claiming therapeutic effect in sexual dysfunction in men. We examined the safety and efficacy of VigRX Plus (VXP) - a proprietary polyherbal preparation for improving male sexual function, in a double blind, randomized placebo-controlled, parallel groups, multi-centre study. 78 men aged 25-50 years of age; suffering from mild to moderate erectile dysfunction (ED), participated in this study. Subjects were randomized to receive VXP or placebo at a dose of two capsules twice daily for 12 weeks. The international index of erectile function (IIEF) was the primary outcome measure of efficacy. Other efficacy measures were: Erectile Dysfunction Inventory of Treatment Satisfaction (EDITS), Serum testosterone, Semen analysis, Investigator's Global assessment and Subjects' opinion. In subjects receiving VXP, the IIEF-Erectile Function (EF) scores improved significantly as compared to placebo. After 12 weeks of treatment, the mean (sd) IIEF-EF score at baseline increased from 16.08 (2.87) to 25.08 (4.56) in the VXP group versus 15.86 (3.24) to 16.47 (4.25) in the placebo group (P sexual desire, intercourse satisfaction, and overall satisfaction).There was a significant difference for VXP versus placebo comparison of mean (sd) EDITS scores of patients: 82.31(20.23) vs 36.78(22.53) and partners :(82.75(9.8) vs 18.50(9.44);P global assessment rated VXP therapy as very good to excellent in more than 50% patients and placebo therapy as fair to good in about 25% of patients. Incidence of side effects and subject's rating for tolerability of treatment was similar in both groups. VigRX Plus was well tolerated and more effective than placebo in improving sexual function in men. Clinical Trial Registry India, CTRI/2009/091/000099, 31-03-2009.

    Profound pulpal anesthesia in mandibular molars with irreversible pulpitis (IP) is often difficult to obtain and often requires supplemental injections after an ineffective inferior alveolar nerve block (IANB). The purpose of this prospective, randomized, double-blind study was to compare the efficacy of 4% articaine with 2% lidocaine for supplemental buccal infiltrations (BIs) after an ineffective IANB in mandibular molars with IP. In addition, the use of articaine for IANB and intraosseous injections was investigated. One hundred emergency patients diagnosed with IP of a mandibular molar were selected and received an IANB with 4% articaine. All injections were 1.7 mL with 1:100,000 epinephrine. All patients reported profound lip numbness after IANB. Patients with ineffective IANB (positive pulpal response to cold or pain on access) randomly received 4% articaine or 2% lidocaine as a supplemental BI. Endodontic access was initiated 5 minutes after deposition of the infiltration solution. Success was defined as no pain or no more than mild pain during endodontic access and instrumentation as measured on a visual analogue scale. Seventy-four patients failed to achieve pulpal anesthesia after IANB with 4% articaine, resulting in IANB success rate of 26%. Success rates for supplemental BIs were 62% for articaine and 37% for lidocaine (P < .05). This effect was most pronounced in second molars (P < .05). Supplemental BI with articaine was significantly more effective than lidocaine. The IANB success rate of 4% articaine confirmed published data. Copyright © 2014 American Association of Endodontists.

    Eating habits may influence the life span and the quality of ageing process by modulating inflammation. The RISTOMED project was developed to provide a personalized and balanced diet, enriched with or without nutraceutical compounds, to decrease and prevent inflammageing, oxidative stress and gut microbiota alteration in healthy elderly people. This paper focused on the effect on inflammation and metabolism markers after 56 days of RISTOMED diet alone or supplementation with three nutraceutical compounds. A cohort of 125 healthy elderly subjects was recruited and randomized into 4 arms (Arm A, RISTOMED diet; Arm B, RISTOMED diet plus VSL#3 probiotic blend; Arm C, RISTOMED diet plus AISA d-Limonene; Arm D, RISTOMED diet plus Argan oil). Inflammatory and metabolism parameters as well as the ratio between Clostridium cluster IV and Bifidobacteria (CL/B) were collected before and after 56 days of dietary intervention, and their evolution compared among the arms. Moreover, participants were subdivided according to their baseline inflammatory parameters (erythrocytes sedimentation rate (ESR), C-Reactive Protein, fibrinogen, Tumor Necrosis Factor-alfa (TNF-α), and Interleukin 6) in two clusters with low or medium-high level of inflammation. The evolution of the measured parameters was then examined separately in each cluster. Overall, RISTOMED diet alone or with each nutraceutical supplementation significantly decreased ESR. RISTOMED diet supplemented with d-Limonene resulted in a decrease in fibrinogen, glucose, insulin levels and HOMA-IR. The most beneficial effects were observed in subjects with a medium-high inflammatory status who received RISTOMED diet with AISA d-Limonene supplementation. Moreover, RISTOMED diet associated with VSL#3 probiotic blend induced a decrease in the CL/B ratio. Overall, this study emphasizes the beneficial anti-inflammageing effect of RISTOMED diet supplemented with nutraceuticals to control the inflammatory status of elderly

    The increasing availability and use of sports supplements is of concern as highlighted by a number of studies reporting endocrine disruptor contamination in such products. The health food supplement market, including sport supplements, is growing across the Developed World. Therefore, the need to ensure the quality and safety of sport supplements for the consumer is essential. The development and validation of two reporter gene assays coupled with solid phase sample preparation enabling the detection of estrogenic and androgenic constituents in sport supplements is reported. Both assays were shown to be of high sensitivity with the estrogen and androgen reporter gene assays having an EC{sub 50} of 0.01 ng mL{sup -1} and 0.16 ng mL{sup -1} respectively. The developed assays were applied in a survey of 63 sport supplements samples obtained across the Island of Ireland with an additional seven reference samples previously investigated using LC-MS/MS. Androgen and estrogen bio-activity was found in 71% of the investigated samples. Bio-activity profiling was further broken down into agonists, partial agonists and antagonists. Supplements (13) with the strongest estrogenic bio-activity were chosen for further investigation. LC-MS/MS analysis of these samples determined the presence of phytoestrogens in seven of them. Supplements (38) with androgen bio-activity were also selected for further investigation. Androgen agonist bio-activity was detected in 12 supplements, antagonistic bio-activity was detected in 16 and partial antagonistic bio-activity was detected in 10. A further group of supplements (7) did not present androgenic bio-activity when tested alone but enhanced the androgenic agonist bio-activity of dihydrotestosterone when combined. The developed assays offer advantages in detection of known, unknown and low-level mixtures of endocrine disruptors over existing analytical screening techniques.

    The primary aim of this study was to examine the self-reported, routine clinical practice behaviors of Australian optometrists with respect to advice regarding smoking, diet and nutritional supplementation. The study also sought to assess the potential influence of practitioner age, gender, practice location (major city versus regional), therapeutic-endorsement status and personal nutritional supplementation habits upon management practices in these areas. A survey was electronically distributed to Australian optometrists (n = 4,242). Respondents anonymously provided information about their personal demographics and lifestyle behaviors (i.e., age, gender, practice location, therapeutic-endorsement status, smoking status, nutritional supplement intake) and routine patient management practices with respect to advice across three domains: smoking, diet and nutritional supplementation. Multivariate logistic regression analyses were performed to assess for potential effects of the listed factors on practitioner behavior. A total of 283 completed surveys were received (completed survey response rate: 6.7%). Fewer than half of respondents indicated routinely asking their patients about smoking status. Younger practitioners were significantly (p smoking behaviors, but this did not extend to counseling for smoking cessation. Almost two-thirds of respondents indicated routinely counseling patients about diet. About half of practitioners specified routinely asking their patients about nutritional supplement intake; this form of questioning was significantly more likely if the respondent was female (p smoking status, diet and nutritional supplement behaviors, being key modifiable lifestyle risk factors with long-term implications for eye health.

    The aim of the study was to estimate the physical activity (PA) level among the professional college students in North India. One hundred three professional college students in the age group of 18-25 years were recruited by simple random sampling for this cross-sectional online survey. The survey was advertised on the social networking sites (Facebook, WhatsApp) through a link www.surveymonkey.com/r/MG-588BY. A Short Form of International Physical Activity Questionnaire was used for this survey study. The questionnaire included total 8 questions on the basis of previous 7 days. The questionnaire consists of 3 main categories which were vigorous, moderate and high PA. Time spent in each activity level was multiplied with the metabolic equivalent of task (MET), which has previously set to 8.0 for vigorous activity, 4.0 for moderate activity, 3.3 for walking, and 1.5 for sitting. By multiplying MET with number of days and minutes performed weekly, amount of each activity level was calculated and measured as MET-min/wk. Further by adding MET minutes for each activity level, total MET-min/wk was calculated. Total number of 100 students participated in this study, and it was shown that all professional course students show different levels in PA. The total PA level among professional college students, which includes, physiotherapy, dental, medical, nursing, lab technician, pharmacy, management, law, engineering, were 434.4 (0-7,866), 170.3 (0-1,129), 87.7 (0-445), 102.8 (0-180), 469 (0-1,164), 0 (0-0), 645 (0-1,836), 337 (0-1,890), 396 (0-968) MET-min/wk respectively. PA levels among professional college students in North India have been established.

    Enhanced dietary intake of omega-3 fatty acids may benefit persons with increased cardiovascular risk, among them obese subjects. Incorporation of omega-3 fatty acids into the plasma lipids is a prerequisite to achieve the favorable effects; however, only very few data are available on the dose of omega-3 fatty acid supplementation in children. The aim of our study was to examine the effects of the consumption of a diet supplemented with 1000 mg alpha-linolenic acid daily on plasma lipids in obese children. In this two times six-week-long, placebo-controlled, crossover study, 9 obese children (age: 13.1 [2.5] years, body mass index: 31.2 [6.2] kg/m 2 ), median [IQR]) incorporated into their diet one egg and one meatball (50 g) per day from hens fed diets containing flaxseed oil, i.e. supplementary dietary intake of 1000 mg alpha-linolenic acid per day was provided. The fatty acid composition of plasma lipids was determined by high-resolution gas-liquid chromatography. Tendencies of increase were observed in the alpha-linolenic acid content of plasma lipids in the phospholipid, triacyl-glycerine and sterol-ester fractions after the supplementation with alpha-linolenic acid. In the non-esterified fatty acid fraction, the values of alpha-linolenic acid were significantly higher after the supplementation (0.11 [0.08] versus 0.14 [0.20], % weight/weight, p < 0.05), indicating the beginning of the accumulation of alpha-linolenic acid in plasma lipids. In obese children a six-week-long supplementation of the diet with 1000 mg alpha-linolenic acid per day increased significantly the contribution of omega-3 fatty acids only to the non-esterified fatty acids of plasma lipids, but had no significant effect on the esterified fractions. Increase of the dose of supplementation may be needed to influence omega-3 fatty acid status in obese children.

    Laryngeal dystonia (LD) is a task-specific focal dystonia of unknown pathophysiology affecting speech production. We examined the demographics of anecdotally reported alcohol use and its effects on LD symptoms using an online survey based on Research Electronic Data Capture (REDCap™) and National Spasmodic Dysphonia Association’s patient registry. From 641 participants, 531 were selected for data analysis, and 110 were excluded because of unconfirmed diagnosis. A total of 406 patients (76.5%) had LD and 125 (23.5%) had LD and voice tremor (LD/VT). The consumption of alcohol was reported by 374 LD (92.1%) and 109 LD/VT (87.2%) patients. Improvement of voice symptoms after alcohol ingestion was noted by 227 LD (55.9% of all patients) and 73 LD/VT (58.4%), which paralleled the improvement observed by patient’s family and/or friends in 214 LD (57.2%) and 69 LD/VT (63.3%) patients. The benefits lasted 1–3 hours in both groups with the maximum effect after 2 drinks in LD patients (p = 0.002), whereas LD/VT symptoms improved independent of the consumed amount (p = 0.48). Our data suggest that isolated dystonic symptoms, such as in LD, are responsive to alcohol intake and this responsiveness is not attributed to the presence of VT, which is known to have significant benefits from alcohol ingestion. Alcohol may modulate the pathophysiological mechanisms underlying abnormal neurotransmission of γ-aminobutyric acid (GABA) in dystonia and as such provide new avenues for novel therapeutic options in these patients.

    The purpose of this study is to examine the relationship between the protein supplements intake satisfaction level and repurchase intention of university students majoring in physical education and verify the mediation effects of word-of-mouth intention. To achieve the purpose of this study, 700 university students majoring in physical education from 10 universities in Korea were selected from October 2013 to December 2013 as the target of this study through the cluster random sampling and data of 228 university students who had experience in the intake of protein supplements among them was analyzed. The composite reliability of each factor was in between 0.869 and 0.958, and the convergent validity and discriminant validity were verified. SPSS 18.0 and Amos 22.0 were utilized as data processing methods and the verification of significance on the medication effects and indirect effects of word-of-mouth intention was carried out using the frequency analysis, correlation analysis, CFA, SEM, and Amos bootstrapping. The result is as follows. The protein supplements intake satisfaction level had a positive effect on the word-of-mouth intention and the word-of-mouth intention had a positive effect on the repurchase intention. Also, it was shown that the word-of-mouth intention played a full mediation role between the intake satisfaction level and the repurchase intention.

    Full Text Available Abstract Background This study evaluated a specialized whey fraction (Prolibra™, high in leucine, bioactive peptides and milk calcium for use as a dietary supplement to enhance weight loss. Methods This was a randomized, double-blind, parallel-arm, 12-week study. Caloric intake was reduced 500 calories per day. Subjects consumed Prolibra or an isocaloric ready-to-mix beverage 20 minutes before breakfast and 20 minutes before dinner. Body fat and lean muscle tissue were measured by dual-energy x-ray absorptiometry (DEXA. Body weight and anthropometric measurements were recorded every 4 weeks. Blood samples were taken at the beginning and end of the study. Statistical analyses were performed on all subjects that completed (completer analysis and all subjects that lost at least 2.25 kg of body weight (responder analysis. Within group significance was determined at P Results Both groups lost a significant amount of weight and the Prolibra group tended to lose more weight than the control group; however the amount of weight loss was not significantly different between groups after 12 weeks. Prolibra subjects lost significantly more body fat compared to control subjects for both the completer (2.81 vs. 1.62 kg P = 0.03 and responder (3.63 vs. 2.11 kg, P = 0.01 groups. Prolibra subjects lost significantly less lean muscle mass in the responder group (1.07 vs. 2.41 kg, P = 0.02. The ratio of fat to lean loss (kg fat lost/kg lean lost was much larger for Prolibra subjects for both completer (3.75 vs. 1.05 and responder (3.39 vs. 0.88 groups. Conclusion Subjects in both the control and treatment group lost a significant amount of weight with a 500 calorie reduced diet. Subjects taking Prolibra lost significantly more body fat and showed a greater preservation of lean muscle compared to subjects consuming the control beverage. Because subjects taking Prolibra lost 6.1% of their body fat mass, and because a 5% reduction of body fat mass has been shown to

    The Infant Fish Oil Supplementation Study is a double-blind randomised controlled trial investigating whether the incidence of allergic disease can be reduced and developmental outcomes enhanced through supplementation with omega-3 fatty acids. Infants at high risk of developing allergic disease will be randomised to receive either fish oil or olive oil supplements until 6 months of age and followed up at six postnatal clinic visits to assess allergy outcomes and infant neurodevelopment. Study groups to consist of a treatment group allocated to receive 650 mg of fish oil daily (250-280 mg docosahexaenoic acid and at least 60 mg eicosapentaenoic acid and a placebo group (olive oil) from birth to 6 months of age. Allergy outcomes will be assessed by clinical history, clinical assessments and allergen skin prick tests at the 12, 30 and 60 month visits. Neurodevelopmental assessments to be conducted at 18 months, and language questionnaires at 12, 18 and 30 months. Samples will be collected from mothers antenatally, from infants at birth, and at clinic visits from 6 months onwards for immunological assessments. Fatty acid composition to be measured in erythrocytes and plasma (at birth and after the supplementation period) to assess the effect of the intervention on fatty acid status. Information on medical history, diet and other lifestyle factors at an antenatal clinic visit and postnatal clinic visits will also be collected. This study is designed to examine clinically relevant effects of a novel, non-invasive and potentially low cost approach to reduce the incidence of allergic disease and facilitate neurodevelopment during early childhood.

    Numerous studies have revealed that study skills have a constructive role on the academic performance of students, in addition to educational quality, student' intelligence, and their affective characteristics. This study aims to examine study skills and the factors influencing them among the health sciences students of Urmia University of Medical Sciences in Iran. This was a cross-sectional study carried out from May to November 2013. A total of 340 Urmia health sciences students were selected using a simple sampling method. Data were collected using the Study Skills Assessment Questionnaire of Counseling Center of Houston University and analyzed with descriptive and analytical statistics. The mean and standard deviation of the students' study skills were 172.5±23.2, out of a total score of 240. Around 1.2% of the study skills were weak; 86.8%, moderate; and 12%, good. Among the study skills, the scores of time management, and memory and concentration were better than the others. Also, there was a significant positive correlation between study skills scores and the students' family housing status and academic level (Pstudy skills, these were not sufficient and far from good. Improving and promoting the study skills of university students require the designing and implementing of education programs for study strategies. Therefore, decision makers and planners in the educational areas of universities should consider the topic described above.

    Full Text Available Selenium (Se is an essential oligonutrient, as a component of several Se-containing proteins (selenoproteins, which exert important biological functions within an organism. In livestock, Se-enriched products have been proposed as dietary supplements to be included into functional feeds for animal preventive health care. To this end, it is important to understand the optimal range of concentrations for supplementation and how long it takes to be assimilated into the organism.In this study, rainbow trout (Oncorhynchus mykiss were fed a control diet containing 0.9 g Kg-1 Se or the same diet supplemented with a Se-Yeast product (Sel-Plex to achieve Se concentrations ranging from 1.5-8.9 g Kg-1 for a period of ten weeks. Fish were sampled every two weeks for analysis. The kinetics of Se bioaccumulation and the effects on fish selenoprotein expression was determined in different tissues combining chemical and bimolecular techniques.The Sel-Plex enriched diets did not have any effect on survival and growth performance. The highest Se levels were found in liver and kidney followed by muscle and blood cells. Analysis of the Se concentration factor showed that liver is able to initially regulate the amount of Se accumulated. However, with higher dietary Se level (4.8 and 8.9 g Kg-1 and longer times of exposure (10 weeks, regulation is ineffective and the Se tissue concentration increases. The expression of the selected trout selenoprotein transcripts showed an inverse correlation with Sel-Plex augmentation in most cases. In liver, kidney and blood cells the highest up-regulation of the trout selenoprotein genes was seen mostly in the group fed the diet enriched with the lowest concentration of Sel-Plex (0.5 g Kg-1 for 10 weeks.Sel-Plex may represent an excellent Se supplement to deliver a high level of Se without provoking harm to the fish and to guarantee the maximal absorption of the element. According to our results, a dietary supplementation of Sel

    Full Text Available Andrea Oleñik,1 Ignacio Jiménez-Alfaro,1 Nicolás Alejandre-Alba,1 Ignacio Mahillo-Fernández2 1Department of Ophthalmology, Jiménez Díaz Foundation, Madrid, Spain; 2Department of Statistics, Jiménez Díaz Foundation, Madrid, Spain Background: Dysfunction of the meibomian gland (MG is among the most frequent causes of ophthalmological symptoms. The inflammation seen in meibomian gland dysfunction (MGD is part of its pathogenesis, and evidence of the antioxidant-inflammatory properties of omega-3 fatty acids suggests this to be an appropriate treatment for MGD. Objective: We aimed to assess the effectiveness of omega-3 fatty acids versus placebo, in improving the symptoms and signs of MGD. Methods: We conducted a randomized and double-mask trial of 3 months duration. We enrolled 61 patients who presented with symptomatic MGD and no tear instability (defined as tear breakup time [TBUT] <10 seconds. Participants were randomly assigned to two homogeneous subgroups. For patients in group A, the study treatment included cleaning the lid margins with neutral baby shampoo and use of artificial tears without preservatives, plus a placebo oral agent. For patients in group B, the study treatment included cleaning the lid margins with neutral baby shampoo and use of artificial tears without preservatives, plus oral supplementation with omega-3 fatty acids.

    Full Text Available Cardiovascular disease (CVD remains one of the major causes of death and disability worldwide. In addition to drug treatment, nutritional interventions or supplementations are becoming a health strategy for CVD prevention. Phytosterols (PhyS are natural components that have been shown to reduce cholesterol levels; while poly-unsaturated fatty acids (PUFA, mainly omega-3 (ω3 fatty acids, have shown to reduce triglyceride levels. Here we aimed to investigate whether the proteins in the main lipoproteins (low density lipoproteins (LDL and high density lipoproteins (HDL as well as proteins in the lipid free plasma fraction (LPDP were regulated by the intake of PhyS-milk or ω3-milk, in overweight healthy volunteers by a proteomic based systems biology approach. The study was a longitudinal crossover trial, including thirty-two healthy volunteers with body mass index (BMI 25–35 kg/m2 (Clinical Trial: ISRCTN78753338. Basal samples before any intervention and after 4 weeks of intake of PhyS or ω3-milk were analyzed. Proteomic profiling by two dimensional electrophoresis (2-DE followed by mass spectrometry-(MALDI/TOF, ELISA, Western blot, conventional biochemical analysis, and in-silico bioinformatics were performed. The intake of PhyS-milk did not induce changes in the lipid associated plasma protein fraction, whereas ω3-milk significantly increased apolipoprotein (Apo- E LDL content (p = 0.043 and induced a coordinated increase in several HDL-associated proteins, Apo A-I, lecitin cholesterol acyltransferase (LCAT, paraoxonase-1 (PON-1, Apo D, and Apo L1 (p < 0.05 for all. Interestingly, PhyS-milk intake induced a reduction in inflammatory molecules not seen after ω3-milk intake.

  9. Cardiovascular Effects of Calcium Supplements

    Directory of Open Access Journals (Sweden)

    Full Text Available Calcium supplements reduce bone turnover and slow the rate of bone loss. However, few studies have demonstrated reduced fracture incidence with calcium supplements, and meta-analyses show only a 10% decrease in fractures, which is of borderline statistical and clinical significance. Trials in normal older women and in patients with renal impairment suggest that calcium supplements increase the risk of cardiovascular disease. To further assess their safety, we recently conducted a meta-analysis of trials of calcium supplements, and found a 27%–31% increase in risk of myocardial infarction, and a 12%–20% increase in risk of stroke. These findings are robust because they are based on pre-specified analyses of randomized, placebo-controlled trials and are consistent across the trials. Co-administration of vitamin D with calcium does not lessen these adverse effects. The increased cardiovascular risk with calcium supplements is consistent with epidemiological data relating higher circulating calcium concentrations to cardiovascular disease in normal populations. There are several possible pathophysiological mechanisms for these effects, including effects on vascular calcification, vascular cells, blood coagulation and calcium-sensing receptors. Thus, the non-skeletal risks of calcium supplements appear to outweigh any skeletal benefits, and are they appear to be unnecessary for the efficacy of other osteoporosis treatments.

    Full Text Available Beta Glucan food supplements have been reported to be of benefit in diabetes and hyperlipidemia. We report a pilot study of the effects of Nichi Glucan, 1, 3-1, 6 Beta Glucan food supplement, in lowering the blood glucose and lipid levels in three patients with noninsulin-dependent diabetes mellitus (NIDDM from India. These patients had increased blood glucose and lipid levels inspite of routine antidiabetic and lipid level lowering medications. Each of the participants took 1.5 g of Nichi Glucan per day with food for two months along with their routine medications. The relevant parameters to assess glycemic status and lipid levels were calculated at the baseline and at the end of two months. After two months of continuous consumption, in one patient, the HbA1c decreased from 9.1% to 7.8%, and the glycemic target of HbA1c <6.5% laid down by the International Diabetes Federation was reached in two patients. Lipid levels also decreased significantly. Based on our findings, Nichi Glucan food supplement can be considered along with routine medications in patients with Type II diabetes with hyperlipidemia. Further studies are needed to validate the results.

    This article examines evidence showing that the use of key dietary supplements can reduce overall disease treatment-related hospital utilization costs associated with coronary heart disease (CHD) in the United States among those at a high risk of experiencing a costly, disease-related event. Results show that the potential avoided hospital utilization costs related to the use of omega-3 supplements at preventive intake levels among the target population can be as much as $2.06 billion on average per year from 2013 to 2020. The potential net savings in avoided CHD-related hospital utilization costs after accounting for the cost of omega-3 dietary supplements at preventive daily intake levels would be more than $3.88 billion in cumulative health care cost savings from 2013 to 2020. Furthermore, the use of folic acid, B6, and B12 among the target population at preventive intake levels could yield avoided CHD-related hospital utilization costs savings of an average savings of $1.52 billion per year from 2013 to 2020. The potential net savings in avoided CHD-related health care costs after accounting for the cost of folic acid, B6, and B12 utilization at preventive daily intake levels would be more than $5.23 billion in cumulative health care cost net savings during the same period. Thus, targeted dietary supplement regimens are recommended as a means to help control rising societal health care costs, and as a means for high-risk individuals to minimize the chance of having to deal with potentially costly events and to invest in increased quality of life.

    Full Text Available Abstract Background Deficiency of macro and micro-minerals in the ration of dairy cows adversely affects growth, milk production and reproduction efficiency. It is essential to examine mineral concentrations in feeds offered to dairy cows in practical farms. Methods Two villages from each taluka were selected at random for taking representative samples of feeds, forages and hair. Within the village, help was sought from village milk producers and district animal husbandry officer for identification of 4 to 5 farmers and collection of representative samples. All the samples were processed and analyzed for chemical composition as well as major macro and micro-minerals, using Inductively Coupled Plasma-Optical Emission Spectrometer. Results Ca content in wheat straw (0.29%, crushed maize (0.02% and wheat bran (0.12% was found to be below the critical level (0.30%. The P content in concentrate ingredients was high (0.26–0.96%, but low in dry roughages (0.06–0.12%. Cereal straws (0.14% and grains (0.12% were deficient in Mg. Feeds and forages were found to be adequate in K (1.50%. Cereals straws were found to be deficient in S (0.11%. Greens were good source of Cu (12.02 ppm. Wheat straw was found to be low in Zn (18 ppm, but high in Mn (225 ppm and Fe (509 ppm. Local grasses and azolla green were found to be rich source of Co (>1.00 ppm. Se (0.63 ppm was present in appreciable quantities in most of the feedstuffs. Conclusions From the present study, it was apparent that the feeds and forages available in the state of Jharkhand may not meet the requirements for Ca, P, Mg, Cu, Zn and Co in order to sustain a milk production of ~10 kg/day. Therefore, it is necessary to supplement these deficient minerals through area specific mineral mixture in the ration of dairy cows for improving productivity and reproduction efficiency.

    Dried plum has been reported to have potent effects on bone in osteopenic animal models, but the mechanisms through which bone metabolism is altered in vivo remain unclear. To address this issue, a study comparing the metabolic response of dried plum to the anabolic agent, parathyroid hormone (PTH), was undertaken. Six month-old female Sprague Dawley rats (n=84) were sham-operated (SHAM) or ovariectomized (OVX) and maintained on a control diet for 6wks until osteopenia was confirmed. Treatments were initiated consisting of a control diet (AIN-93M) supplemented with dried plum (0, 5, 15 or 25%; w/w) or a positive control group receiving PTH. At the end of 6wks of treatment, whole body and femoral bone mineral density (BMD) were restored by the two higher doses of dried plum to the level of the SHAM group. Trabecular bone volume and cortical thickness were also improved with these two doses of dried plum. Dried plum suppressed the OVX-induced increase in bone turnover as indicated by systemic biomarkers of bone metabolism, N-terminal procollagen type 1 (P1NP) and deoxypyridinoline (DPD). Dynamic bone histomorphometric analysis of the tibial metaphysis revealed that dried plum restored the OVX-induced increase in cancellous bone formation rate (BFR) and mineralizing surface (MS/BS) to the SHAM group, but some doses of dried plum increased endocortical mineral apposition rate (MAR). As expected, PTH significantly increased endocortical MAR and BFR, periosteal BFR, and trabecular MAR and BFR beyond that of the OVX and maintained the accelerated rate of bone resorption associated with OVX. Dried plum up-regulated bone morphogenetic protein 4 (Bmp4) and insulin-like growth factor 1 (Igf1) while down-regulating nuclear factor T cell activator 1 (Nfatc1). These findings demonstrate that in the adult osteopenic OVX animal, the effects of dried plum differ from that of PTH in that dried plum primarily suppressed bone turnover with the exception of the indices of bone

  20. INTEGRATED SURVEY FOR ARCHITECTURAL RESTORATION: A METHODOLOGICAL COMPARISON OF TWO CASE STUDIES

    2016-06-01

    Full Text Available A preliminary survey campaign is essential in projects of restoration, urban renewal, rebuilding or promotion of architectural heritage. Today several survey techniques allow full 3D object restitution and modelling that provides a richer description than simple 2D representations. However, the amount of data to collect increases dramatically and a trade-off between efficiency and productivity from one side and assuring accuracy and completeness of the results on the other must be found. Depending on the extent and the complexity of the task, a single technique or a combination of several ones might be employed. Especially when documentation at different scales and with different levels of detail are foreseen, the latter will likely be necessary. The paper describes two architectural surveys in Italy: the old village of Navelli (AQ, affected by the earthquake in 2009, and the two most relevant remains in Codiponte (MS, damaged by the earthquake in 2013, both in the context of a project of restoration and conservation. In both sites, a 3D survey was necessary to represent effectively the objects. An integrated survey campaign was performed in both cases, which consists of a GPS network as support for georeferencing, an aerial survey and a field survey made by laser scanner and close range photogrammetry. The two case studies, thanks to their peculiarities, can be taken as exemplar to wonder if the integration of different surveying techniques is today still mandatory or, considering the technical advances of each technology, it is in fact just optional.

    This report is published as a product of the National Waste Terminal Storage (NWTS) Program. The objective of this program is the development of terminal waste storage facilities in deep stable geologic formations for high-level nuclear wastes, including spent fuel elements from commercial power reactors and transuranic nuclear waste for which the federal government is responsible. This report is part of the location and site characterization phase and contains threatened and endangered species information for the Gibson Dome and Elk Ridge study areas of the Paradox Region. The threatened and endangered species information was obtained through site surveys designed and implemented by area experts. The site surveys were performed during the period late summer 1981 - spring 1982 in the Gibson Dome and Elk Ridge Study Areas. No threatened or endangered species were identified in either Lavender or Davis canyons. Additional studies at the borehole locations in Beef Basin did identify the nearest occurrence of a species proposed for endangered status (Astragalus monumentalis, a monument milkvetch, member of the legume family). The species was identified approximately 160 to 300 m (500 to 1000 ft) from a hydro testing drill site. Consequently, construction and operation activity should not cause any adverse impacts. This report will be used to satisfy Section 7 requirements of the Endangered Species Act (PL 93-205 as amended) and to allow the United States Fish and Wildlife Service to verify that no protected species are subject to disturbance as the result of project activities occurring in the Gibson Dome and Elk Ridge study areas

    To investigate whether osteoporosis or use of calcium supplementations predict all-cause mortality, or death from CVD, in a longitudinal cohort of patients with rheumatoid arthritis (RA). Patients in the Oslo RA register (ORAR) were examined, and bone mineral density was measured in 1996. The cohort was linked to the Norwegian Cause of Death registry on December 31, 2010. Death from CVD was defined in 3 following different outcomes: (1) primary atherosclerotic death, (2) atherosclerotic death as one of the 5 listed causes of death, and (3) CVD according to World Health Organization (WHO) definition as primary cause of death. Baseline predictors of all-cause mortality and death from CVD were identified in separate Cox regression models, using backwards selection. Sensitivity analyses were performed including analyses of interactions and competing risk. A total of 609 patients were examined in 1996/1997. By December 31, 2010, 162 patients (27%) had died, resulting in 7439 observed patient-years. Of the deceased, 40 (24.7%) had primary atherosclerotic death. In the final model of all-cause mortality increased baseline ESR [hazard ratio (HR) 1.02 per mm/h, 95% CI: 1.01-1.03], calcium supplementation (1.74, 1.07-2.84), and osteoporosis, defined as a T score ≤2.5 SD at any location, (1.58, 1.07-2.32) predicted higher mortality rates, in models adjusted for age, gender, and a propensity score. In the final model of primary atherosclerotic death, increased ESR (1.03 per mm/h, 1.01-1.05) and calcium supplementation (3.39, 1.41-8.08), predicted higher mortality. Increased baseline ESR and use of calcium supplementation were predictors of increased all-cause mortality and risk of death from CVD in this longitudinal study of patients with RA.

    The present study evaluated whether oral supplementation with a branched-chain amino acid (BCAA) improves the biochemical and amino acid profiles of liver tumor patients undergoing radiotherapy. Patients were randomly assigned to one of 2 groups: a group given oral supplementation with BCAA granules (LIVACT granules; Samil Pharm Co., Korea, each granule containing L-isoleucine 952 mg, L-leucine 1,904 mg, and L-valine 1,144 mg) during radiotherapy, or a placebo group. Physical and biochemical examinations and measurements, including subjective symptoms, Child-Pugh class, body mass index, plasma albumin concentration, and plasma amino acid profiles were monitored. Fifty were enrolled between November 2005 and November 2006. We also analyzed data from 37 hepatocellular carcinoma (HCC) patients in order to evaluate a more homogenous group. The two groups of patients were comparable in terms of age, gender, Child-Pugh score, and underlying hepatitis virus type. Serum albumin, total protein, liver enzymes, and cholesterol showed a tendency to increase in the BCAA group. In this group, the percentage of cases that reverted to normal serum albumin levels between 3 and 10 weeks after administration of BCAA was significantly higher (41.18%) than in the placebo group (p=0.043). Oral supplementation with a BCAA preparation seems to help HCC patients undergoing radiotherapy by increasing the BCAA concentration.

    StemSport (SS; StemTech International, Inc. San Clemente, CA) contains a proprietary blend of the botanical Aphanizomenon flos-aquae and several herbal antioxidant and anti-inflammatory substances. SS has been purported to accelerate tissue repair and restore muscle function following resistance exercise. Here, we examine the effects of SS supplementation on strength adaptations resulting from a 12-week resistance training program in healthy young adults. Twenty-four young adults (16 males, 8 females, mean age = 20.5 ± 1.9 years, mass = 70.9 ± 11.9 kg, stature = 176.6 ± 9.9 cm) completed the twelve week training program. The study design was a double-blind, placebo controlled parallel group trial. Subjects either received placebo or StemSport supplement (SS; mg/day) during the training. 1-RM bench press, 1-RM leg press, vertical jump height, balance (star excursion and center of mass excursion), isokinetic strength (elbow and knee flexion/extension) and perception of recovery were measured at baseline and following the 12-week training intervention. Resistance training increased 1-RM strength (p 0.10). These data suggest that compared to placebo, the SS herbal/botanical supplement did not enhance training induced adaptations to strength, balance, and muscle function above strength training alone.

The effect of a 2 month treatment of atopic dogs by food supplementation with a mixture of essential fatty acids was evaluated on skin samples taken before and after the treatment period. Electron microscopy revealed that the non-lesional skin of atopic dogs exhibited an abnormal and largely incomplete structure of the lamellar lipids with little cohesion between the corneocyte strata. The SC of atopic dogs was characterized by a significant decrease in the lipid content when compared to the healthy controls. Following oral supplementation with the mixture of essential fatty acids, the overall lipid content of the SC markedly increased. This feature was observed both with the free and, most importantly, with the protein-bound lipids (cholesterol, fatty acids and ceramides), the latter constituting the corneocyte-bound scaffold for ordinate organisation of the extracellular lipid bi-layers. Indeed, the semi-quantitative electron microscopy study revealed that the treatment resulted in a significantly improved organization of the lamellar lipids in the lower SC, comparable to that of the healthy dogs. Our results indicate the potential interest of long-term alimentary supplementation with omega-6 and omega-3 essential fatty acids in canine atopic dermatitis.

    Multitasking information behaviour is the human ability to handle the demands of multiple information tasks concurrently. When we multitask, we work on two or more tasks and switch between those tasks. Multitasking is the way most of us deal with the complex environment we all live in, and recent studies show that people often engage in…

    Vitamin C supplementation may help reduce the risk of pregnancy complications such as pre-eclampsia, intrauterine growth restriction and maternal anaemia. There is a need to evaluate the efficacy and safety of vitamin C supplementation in pregnancy. To evaluate the effects of vitamin C supplementation, alone or in combination with other separate supplements on pregnancy outcomes, adverse events, side effects and use of health resources. We searched the Cochrane Pregnancy and Childbirth Group's Trials Register (31 March 2015) and reference lists of retrieved studies. All randomised or quasi-randomised controlled trials evaluating vitamin C supplementation in pregnant women. Interventions using a multivitamin supplement containing vitamin C or where the primary supplement was iron were excluded. Two review authors independently assessed trials for inclusion and risk of bias, extracted data and checked them for accuracy. Twenty-nine trials involving 24,300 women are included in this review. Overall, 11 trials were judged to be of low risk of bias, eight were high risk of bias and for 10 trials it was unclear. No clear differences were seen between women supplemented with vitamin C alone or in combination with other supplements compared with placebo or no control for the risk of stillbirth (risk ratio (RR) 1.15, 95% confidence intervals (CI) 0.89 to 1.49; 20,038 participants; 11 studies; I² = 0%; moderate quality evidence), neonatal death (RR 0.79, 95% CI 0.58 to 1.08; 19,575 participants; 11 studies; I² = 0%), perinatal death (average RR 1.07, 95% CI 0.77 to 1.49; 17,105 participants; seven studies; I² = 35%), birthweight (mean difference (MD) 26.88 g, 95% CI -18.81 to 72.58; 17,326 participants; 13 studies; I² = 69%), intrauterine growth restriction (RR 0.98, 95% CI 0.91 to 1.06; 20,361 participants; 12 studies; I² = 15%; high quality evidence), preterm birth (average RR 0.99, 95% CI 0.90 to 1.10; 22,250 participants; 16 studies; I² = 49%; high quality evidence

    The National Immunization Survey (NIS) and the National Health Interview Survey (NHIS) produce national coverage estimates for children aged 19 months to 35 months. The NIS is a cost-effective, random-digit-dialing telephone survey that produces national and state-level vaccination coverage estimates. The National Immunization Provider Record Check Study (NIPRCS) is conducted in conjunction with the annual NHIS, which is a face-to-face household survey. As the NIS is a telephone survey, potential coverage bias exists as the survey excludes children living in nontelephone households. To assess the validity of estimates of vaccine coverage from the NIS, we compared 1995 and 1996 NIS national estimates with results from the NHIS/NIPRCS for the same years. Both the NIS and the NHIS/NIPRCS produce similar results. The NHIS/NIPRCS supports the findings of the NIS.

    Full Text Available This case study on the X Foundation aims to provide an overview and analysis of questionnaire results of exit interviews of employees who came out in 2009 and 2010. This case study was conducted on the basis of the importance of seeing the dimensions or factors that exist, particularly with regard to the factors of satisfaction or dissatisfaction in the employee working within the Organization. The study was conducted using quantitative methods with retrieval of primary data on the X Foundation, the descriptive method. Subjects were 63 employees who came out in 2009 and 125 employees that came out in 2010 at differing position, level and status. The results generally showed that there are two factors that should motivate employees to be the opposite that is causing dissatisfaction in the employee, and there are two factors also confirm the reasons why an employee becomes dissatisfied and decided to leave the organization. The suggestions put forward to conduct further research to further deepen the analysis of descriptive statistics, so the depiction becomes more profound; and can provide accurate advice to the organization.

    Background Monolingual Web survey is a common tool for studying adolescent health. However, national languages may cause difficulties for some immigrant-origin youths, which lower their participation rate. In national surveys, the number of ethnic minority groups is often too small to assess their well-being. Objective We studied the feasibility of a multilingual Web survey targeted at immigrant-origin youths by selection of response language, and compared participation in different language groups with a monolingual survey. Methods The Adolescent Health and Lifestyle Survey (AHLS), Finland, with national languages (Finnish/Swedish) was modified into a multilingual Web survey targeted at a representative sample of 14- and 16-year olds (N=639) whose registry-based mother tongue was other than the national languages. The survey was conducted in 2010 (16-year olds) and 2011 (14-year olds). The response rate of the multilingual survey in 2011 is compared with the AHLS of 2011. We also describe the translation process and the e-form modification. Results Of the respondents, 57.6% answered in Finnish, whereas the remaining 42.4% used their mother tongue (P=.002). A majority of youth speaking Somali, Middle Eastern, Albanian, and Southeast Asian languages chose Finnish. The overall response rate was 48.7% with some nonsignificant variation between the language groups. The response rate in the multilingual Web survey was higher (51.6%, 163/316) than the survey with national languages (46.5%, 40/86) in the same age group; however, the difference was not significant (P=.47). The adolescents who had lived in Finland for 5 years or less (58.0%, 102/176) had a higher response rate than those having lived in Finland for more than 5 years (45.1%, 209/463; P=.005). Respondents and nonrespondents did not differ according to place of birth (Finland/other) or residential area (capital city area/other). The difference in the response rates of girls and boys was nearly significant (P

    This report is a release of digital data from a helicopter electromagnetic and magnetic survey conducted by Fugro Airborne Surveys in areas of eastern Nebraska as part of a joint hydrologic study by the Lower Platte North and Lower Platte South Natural Resources Districts, and the U.S. Geological Survey. The survey flight lines covered 1,418.6 line km (882 line mile). The survey was flown from April 22 to May 2, 2009. The objective of the contracted survey was to improve the understanding of the relation between surface water and groundwater systems critical to developing groundwater models used in management programs for water resources. The electromagnetic equipment consisted of six different coil-pair orientations that measured resistivity at separate frequencies from about 400 hertz to about 140,000 hertz. The electromagnetic data were converted to georeferenced electrical resistivity grids and maps for each frequency that represent different approximate depths of investigation for each survey area. The electrical resistivity data were input into a numerical inversion to estimate resistivity variations with depth. In addition to the electromagnetic data, total field magnetic data and digital elevation data were collected. Data released in this report consist of flight line data, digital grids, digital databases of the inverted electrical resistivity with depth, and digital maps of the apparent resistivity and total magnetic field. The range of subsurface investigation is comparable to the depth of shallow aquifers. The survey areas, Swedeburg and Sprague, were chosen based on results from test flights in 2007 in eastern Nebraska and needs of local water managers. The geophysical and hydrologic information from U.S. Geological Survey studies are being used by resource managers to develop groundwater resource plans for the area.

    Because of the particularly severe perinatal outcomes associated with antenatal Zika virus infection, it is important for prenatal care providers to communicate Zika virus risks and strategies for prevention to their patients. Although face-to-face communication is ideal, clinic visits may not allow for in-depth discussion of all concerns. While previous studies have shown prenatal providers to be pregnant women's most trusted sources of health information, there is little knowledge on what secondary communication modalities pregnant women prefer for receiving information from their providers about an evolving public health emergency. A cross-sectional, descriptive anonymous 27-item survey was distributed to pregnant women at four clinics around Atlanta, Georgia from May 5th to June 20th, 2016. The survey assessed women's interest in and communication preferences about prenatal topics, including Zika virus. Descriptive statistics were calculated and chi-square tests were used to evaluate associations between the primary outcomes and patient characteristics. Four-hundred and eight women completed the survey. The most popular resource for obtaining Zika virus information was the Centers for Disease Control and Prevention (CDC) website (73.0%). While their prenatal provider's own website for Zika information ranked 5th among sources currently accessed for Zika information, it ranked third behind educational brochures and emails for ways in which women wanted to receive information. The characteristics of Zika virus information deemed most important were: evidence-based (87.5%), endorsed by the CDC (74.1%), and endorsed by their own provider (67.9%). In any public health emergency affecting pregnant women, women are going to seek advice from their obstetric providers. Because providers may lack sufficient time to discuss concerns with every patient, they may consider providing patient education in other ways. For the women included in this study, educational brochures

    This study sought to establish if nurses at a community hospital could correctly identify patients at high risk for skin breakdown and determine whether the resources needed to reposition high-risk patients per protocol were available. The sample comprised 101 registered nurses from 8 acute care units in a 246-bed community-owned district Magnet® hospital. The study facility serves patients from a wide geographic area in the "panhandle" of Idaho with a largely rural population. Face-to-face interviews were conducted on all shifts for 4 days. The instrument consisted of demographic questions and patient assignment questions including which patients the nurse identified at high risk for skin breakdown, which patients the nurse received information on about skin risks at change of shift, whether the nurse knew the Norton Pressure Ulcer Scale scores for their patients, whether patients were repositioned, who performed the repositioning, and how many times that shift. Surveyors obtained patients' Norton scores from computer records and recorded whether the nurse correctly identified patients at high-risk for skin breakdown. Most nurses (73%) stated they did not know their patients' Norton scores. About 60% of nurses reported turning their high-risk patients every 2 to 4 hours. The repositioning was completed most often by RNs alone (39%), RN and CNA (36%), and by patients themselves (35%). Reasons for not repositioning included the following: allowed to sleep, off unit, patient refused, not enough time, family refused, pain, not enough help, and patient receiving end-of-life care. Assessment of patient's skin risk status was correct in 232 out of 348 patients (66%). Nurses predicted high risk when the Norton score indicated low risk in 35.9% of patients and low risk when the Norton scale indicated high risk in 35.1%. Nurses reported receiving information about skin risk in 33% of their assigned patients. Nurses reported adequate resources to reposition patients. Most

    Full Text Available In this paper we present the latest experiences carried out by our research group in the field of multimedia communication. Starting from the construction of virtual models, interactive and non-interactive, we pursued the aim to introduce edutainment paths in some museum contexts, both increasing the value of cultural assets and creating an attractive pole for the visitors. The current trends are gradually transforming museums from static places of conservation into active and engaging spaces to deliver accessible culture to the masses, using digital technologies for creating new paradigms of interaction and enhance the experience of the visitor. Here we present two case studies, whose purpose is to bring together the different competences by various experts to test the potential of digital products as non-formal teaching tools to allow a satisfying learning experience. The case explored are those of the Civic Museum of Schifanoia (Ferrara and the octagonal cloister of the Carracci in San Michele in Bosco (Bologna. The multimedia products discussed here relate to these two research themes, and up to now 3 out of 5 planned products have been made (in final mode, or in prototype form. The experimentation led to concrete results that introduced a reflection on what investigative methodologies and protocols are more suitable to be adopted in these cases, in compliance to the aim identified by the project.

    To determine the self-reported prevalence of domestic violence and associated risk factors in the Sivas province of Turkey. Five hundred and eighty-three households were chosen by the method of stratified random sampling. The average age among women was 28.65+/-4.64. A total of 45.3% of women were in 30-34 age-group, 76.5% were housewives, and 91.2% were married. The data were gathered by performing face-to-face interviews in participants' homes. Demographic data were obtained by fill-in forms. We found a statistically significant relationship among the types of violence and annual income, type of family, education and occupation level of women, education level of perpetrators, watching violent films, and childhood experience of emotional abuse or negligence. Fifty-two percent of women were exposed to at least one type of violence. Verbal violence was the most frequent type of violence (53.8%), followed by physical violence (38.3%). About 45% of women exposed to violence were in the 30-34 age group, 41.6% completed only primary schools, 73.6% were housewives, 91.7% were married, 71.0% had been exposed to violence during their childhood, and 45.2%, had been exposed to violence several times in a month. Economic problems were reported as the most important reason for domestic violence (31.4%). Our study found higher prevalence of domestic violence than expected. As an important public health problem, domestic violence requires a multidisciplinary approach to understand its causes and plan preventive measures.

  20. Learning lessons from field surveys in humanitarian contexts: a case study of field surveys conducted in North Kivu, DRC 2006-2008

    Full Text Available Abstract Survey estimates of mortality and malnutrition are commonly used to guide humanitarian decision-making. Currently, different methods of conducting field surveys are the subject of debate among epidemiologists. Beyond the technical arguments, decision makers may find it difficult to conceptualize what the estimates actually mean. For instance, what makes this particular situation an emergency? And how should the operational response be adapted accordingly. This brings into question not only the quality of the survey methodology, but also the difficulties epidemiologists face in interpreting results and selecting the most important information to guide operations. As a case study, we reviewed mortality and nutritional surveys conducted in North Kivu, Democratic Republic of Congo (DRC published from January 2006 to January 2009. We performed a PubMed/Medline search for published articles and scanned publicly available humanitarian databases and clearinghouses for grey literature. To evaluate the surveys, we developed minimum reporting criteria based on available guidelines and selected peer-review articles. We identified 38 reports through our search strategy; three surveys met our inclusion criteria. The surveys varied in methodological quality. Reporting against minimum criteria was generally good, but presentation of ethical procedures, raw data and survey limitations were missed in all surveys. All surveys also failed to consider contextual factors important for data interpretation. From this review, we conclude that mechanisms to ensure sound survey design and conduct must be implemented by operational organisations to improve data quality and reporting. Training in data interpretation would also be useful. Novel survey methods should be trialled and prospective data gathering (surveillance employed wherever feasible.

    In order to study neutron dose measurement in high energy radiation field, a Dual-moderated survey meter in the range from 1 keV to 300 MeV mean energies spectra has been developed. Measurement results of some survey meters depend on the neutron spectra characteristics in different neutron radiation fields, so the characteristics of the responses to various neutron spectra should be studied in order to get more reasonable dose. In this paper the responses of the survey meter were calculated under different neutron spectra data from IAEA of Technical Reports Series No. 318 and other references. Finally one dose estimation method was determined. The range of the reading per H*(10) for the method estimated is about 0.7–1.6 for the neutron mean energy range from 50 keV to 300 MeV. -- Highlights: • We studied a novel high energy neutron survey meter. • Response characteristics of the survey meter were calculated by using a series of neutron spectra. • One significant advantage of the survey meter is that it can provide mean energy of radiation field. • Dose estimate deviation can be corrected. • The range of corrected reading per H*(10) is about 0.7–1.6 for the neutron fluence mean energy range from 0.05 MeV to 300 MeV

    The prevalence of dietary supplement use varies largely among populations, and previous studies have indicated that it is high in the Danish population compared with other European countries. The diversity in supplement use across countries indicates that cultural and environmental factors could influence the use of dietary supplements. Only few studies investigating the use of dietary supplements have been conducted in the Danish population. The present cross-sectional study is based on 54,948 Danes, aged 50-64 years, who completed self-administrated questionnaires on diet, dietary supplements and lifestyle between 1993 and 1997. A health index including smoking, physical activity, alcohol and diet, and a metabolic risk index including waist circumference, urinary glucose and measured hypertension were constructed. Logistic regression was used to investigate these determinants in relation to the intake of dietary supplements. We found that 71 % of the participants were dietary supplement users; female sex, older age groups and higher educated participants were more likely to be users of any dietary supplements. One additional point in the health index was associated with 19, 16 and 9 % higher likelihood of being user of any, more common and less common supplements, respectively. In the metabolic risk index, one additional point was associated with 17 and 16 % lower likelihood of being user of any supplement and more common supplements, respectively. No significant association was found for less common supplement use. In conclusion, those with the healthiest lifestyle were more likely to use dietary supplements. Thus, lifestyle and dietary composition should be considered as confounders on supplement use and health outcomes.

    We aimed to assess whether vitamin D supplementation improves glucose metabolism in adults with type 2 diabetes. PubMed and Cochrane database were searched up to July 1st 2016 for randomized controlled trials that assessed the relationship between vitamin D supplementation and glucose metabolism (change in hemoglobin A1C (HbA1C) and fasting blood glucose (FBG)) among adults with type 2 diabetes. Twenty nine trials (3324 participants) were included in the systematic review. Among 22 studies included in the meta-analysis, 19 reported HbA1C, 16 reported FBG outcomes and 15 were deemed poor quality. There was a modest reduction in HbA1C (-0.32% [-0.53 to -0.10], I 2 =91.9%) compared to placebo after vitamin D supplementation but no effect on FBG (-2.33mg/dl [-6.62 to 1.95], I 2 =59.2%). In studies achieving repletion of vitamin D deficiency (n=7), there were greater mean reductions in HbA1C (-0.45%, [-1.09 to 0.20]) and FBG (-7.64mg/dl [-16.25 to 0.97]) although not significant. We found a modest reduction of HbA1C after vitamin D treatment in adults with type 2 diabetes albeit with substantial heterogeneity between studies and no difference in FBG. Larger studies are needed to further evaluate the glycemic effects of vitamin D treatment especially in patients with vitamin D deficiency. Copyright © 2017 Elsevier Inc. All rights reserved.

    Male pattern baldness, or androgenetic alopecia, affects approximately 50% of the adult population and can cause poor self-image, low self-esteem and have a significant negative impact on the quality of life. An oral nutraceutical supplement based on a marine complex formulation has previously been reported to significantly increase the number of terminal hairs in women with thinning hair. The objective of this double-blind, placebo-controlled study was to confirm the beneficial effects of a similar marine complex supplement in adult male subjects with thinning hair (Viviscal ® Man; Lifes2good, Inc., Chicago, IL, USA). Healthy adult male subjects with thinning hair associated with clinically diagnosed male pattern hair loss were enrolled and randomized to receive study drug or placebo twice daily. At Day 90, subjects indicated a significant improvement in three of six quality of life measures as well as a significant overall improvement in quality of life. After 180 days, significant increases were observed for total hair count, total hair density, and terminal hair density (for each, P = 0.001). The investigator assessments revealed significant improvements in terminal and vellus hair count and terminal hair density. Hair pull test results were significantly lower (fewer hairs removed) for study drug vs. placebo at Days 90 (P < 0.05) and 180 (P < 0.01). There were no reports of treatment-emergent adverse events. The results of this study
