    Diet and nutrition are moving to the forefront of modern primary and preventive care to help address the rising burden of chronic diseases among the general population. Such a movement has yet to occur formally across the field of transplantation. We therefore looked to establish the current base of knowledge regarding diet, nutrition and solid-organ transplantation. A limited number of focused studies looking into the dietary habits of solid-organ transplant patients have been performed and many of the available studies have detailed the nutritional status in the peri-operative period. Frequently described, however, is the heavy incidence of metabolic abnormalities, such as obesity, dyslipidemia and diabetes, occurring after solid-organ transplantation. Optimistically, several studies have noted improvement in several metabolic abnormalities with the use of dietary interventions in the post-transplant period. Despite these positive results, few consensus guidelines for post-transplant diet have been established and nutritional support among transplant programs remains limited. Although there are many hurdles to implementation of detailed dietary recommendations and nutritional support for transplant patients, creating such programs and guidelines could dramatically impact long-term outcomes and burden of chronic metabolic disease for transplant recipients.

    Here, the state of our knowledge regarding the interior dynamics and evolution of habitable terrestrial planets including Earth and super-Earths is reviewed, and illustrated using state-of-the-art numerical models. Convection of the rocky mantle is the key process that drives the evolution of the interior: it causes plate tectonics, controls heat loss from the metallic core (which generates the magnetic field) and drives long-term volatile cycling between the atmosphere/ocean and interior. Geoscientists have been studying the dynamics and evolution of Earth's interior since the discovery of plate tectonics in the late 1960s and on many topics our understanding is very good, yet many first-order questions remain. It is commonly thought that plate tectonics is necessary for planetary habitability because of its role in long-term volatile cycles that regulate the surface environment. Plate tectonics is the surface manifestation of convection in the 2900-km deep rocky mantle, yet exactly how plate tectonics arises is still quite uncertain; other terrestrial planets like Venus and Mars instead have a stagnant lithosphere- essentially a single plate covering the entire planet. Nevertheless, simple scalings as well as more complex models indicate that plate tectonics should be easier on larger planets (super-Earths), other things being equal. The dynamics of terrestrial planets, both their surface tectonics and deep mantle dynamics, change over billions of years as a planet cools. Partial melting is a key process influencing solid planet evolution. Due to the very high pressure inside super-Earths' mantles the viscosity would normally be expected to be very high, as is also indicated by our density function theory (DFT) calculations. Feedback between internal heating, temperature and viscosity leads to a superadiabatic temperature profile and self-regulation of the mantle viscosity such that sluggish convection still occurs.

    Full Text Available Abstract Background There are many challenges involved in running randomised controlled dietary intervention trials that investigate health outcomes. The aim of this paper was to evaluate the recruitment process, retention of participants and challenges faced in our dairy intervention trial, and to provide strategies to combat the difficulties of running long-term dietary intervention trials. Methods A 12-month, randomised, two-way crossover study was conducted in overweight adults with habitually low dairy food consumption to assess the effects of a high dairy intake (4 servings of reduced-fat dairy per day compared with a low dairy intake (1 serving of reduced-fat dairy per day on measures of cardiometabolic and cognitive health. On completion of the high dairy intake phase, each participant was interviewed about their experience in the trial and responses were used to evaluate the key issues for study participants. Results Although the recruitment target was achieved, high rates of attrition (49.3% and difficulties maintaining participant compliance (reported by 37.8% of participants were major threats to the viability of the study. Factors that contributed to the high attrition included inability to comply with the dietary requirements of the study protocol (27.0%, health problems or medication changes (24.3% and time commitment (10.8%. Conclusion Attrition and adherence to study requirements present challenges to trials requiring longer-term dietary change. Including a run-in period to further assess the motivation, commitment and availability of participants, maintaining regular contact with participants during control phases, minimising time commitment, providing flexibility with dietary requirements, facilitating positive experiences, and stringent monitoring of diet are some key recommendations for future dietary intervention trials.

    Cancer of the esophagus is an underestimated, poorly understood, and changing disease. Its overall 5-year survival is less than 20%, even in the United States, which is largely a function of a delay in diagnosis until its more advanced stages. Additionally, the epidemiologic complexities of esophageal cancer are vast, rendering screening and prevention limited at best. First, the prevalence of esophageal cancer is unevenly distributed throughout the world. Second, the two histological forms (squamous cell and adenocarcinoma) vary in terms of their geographic prevalence and associated risk factors. Third, some populations appear at particular risk for esophageal cancer. And fourth, the incidence of esophageal cancer is in continuous flux among groups. Despite the varied prevalence and risks among populations, some factors have emerged as consistent associations while others are only now becoming more fully recognized. The most prominent, scientifically supported, and long-regarded risk factors for esophageal cancer are tobacco, alcohol, and reflux esophagitis. Inasmuch as the above are regarded as important risk factors for esophageal cancer, they are not the sole contributors. Dietary habits, nutrition, local customs, and the environment may be contributory. Along these lines, vitamins, minerals, fruits, vegetables, meats, fats, salted foods, nitrogen compounds, carcinogens, mycotoxins, and even the temperature of what we consume are increasingly regarded as potential etiologies for this deadly although potentially preventable disease. The goal of this review is to shed light on the less known role of nutrition and dietary habits in esophageal cancer.

    Patient non-adherence to medication is a pervasive problem that contributes to poor patient health and high healthcare costs. Basic research and interventions have focused thus far on behaviour initiation factors, such as patients' illness and treatment beliefs. This paper proposes two processes that occur after behaviour initiation that are theorised to contribute to prediction of long-term medication adherence: 'coherence' of patients' beliefs from experiences with treatment and habit development. Seventy-one hypertensive patients reported their treatment-related beliefs, experiences related to treatment efficacy and medication-taking habit strength in a baseline interview. Patients then used an electronic monitoring pill bottle for approximately one month. Patients' medication habit-strength was the strongest predictor of all adherence measures, explaining 6-27% incremental variance in adherence to that explained by patients' treatment-related beliefs. Patients' beliefs and experiences did not predict overall adherence, even for patients with 'weaker' habits. However, patients' experiences were found to predict intentional non-adherence and habit strength was found to predict unintentional adherence. Practitioners may assess patients' medication-taking habits to get an initial view of their likely adherence to long-term medications. Future research should assess the current theoretical predictions in a hypertension inception sample and in populations with symptomatic conditions.

    Following gastric bypass surgery, patients must make dramatic dietary changes, but little is known about patients' perspectives on long-term dietary management after this surgery. This grounded theory, qualitative study sought to advance conceptual understanding of food choice by examining how gastric bypass patients constructed personal food systems to guide food and eating behaviors 12 months post-surgery. Two in-depth interviews were conducted with each of 16 adults, purposively sampled from bariatric support groups. Using constant comparative analysis of verbatim interview transcripts, researchers identified participants' goal-strategy-monitoring networks representing how participants used specific food and eating behaviors towards their main goals of: Weight Management, Overall Health, Avoiding Negative Reactions to Eating, and Integrating Dietary Changes with Daily Life. Linked to each main goal was a hierarchy of intermediary goals, strategies, and tactics. Participants used monitoring behaviors to assess strategy effectiveness towards goal achievement. Individuals' Weight Management networks were compared to uncover similarities and differences among strategy use and monitoring methods among those who maintained weight loss and those who regained weight. The complex, multilevel goal-strategy-monitoring networks identified illustrate the "work" involved in constructing new personal food systems after surgery, as well as advance understanding of strategies as a component of people's personal food systems. These findings provide researchers and practitioners with insight into the long-term dietary issues that gastric bypass patients face and a potential method for representing how people relate deliberate dietary behaviors to their goals.

    Little is known about the long-term effects of chronic exposure to low-level organophosphate (OP) pesticides, and the role of neurotransmitter systems, other than the cholinergic system, in mediating OP neurotoxicity. In this study, rats were administered 5mg/kg/day of chlorpyrifos (CPF) for 6 months commencing at 3-months-of-age. The animals were examined 7 months later (at 16-months-of-age) for spatial learning and memory in the Morris water maze (MWM) and locomotor activity. In addition, we assessed the chronic effects of CPF on glutamatergic and gamma-aminobutyric acid (GABAergic) function using pharmacological challenges with dizocilpine (MK801) and diazepam. Impaired performance related to altered search patterns, including thigmotaxis and long-term spatial memory was noted in the MWM in animals exposed to CPF, pointing to dietary CPF-induced behavioral disturbances, such as anxiety. Twenty-four hours after the 31st session of repeated acquisition task, 0.1mg/kg MK801, an N-methyl-d-aspartate (NMDA) antagonist was intraperitoneally (i.p.) injected for 4 consecutive days. Decreased latencies in the MWM in the control group were noted after two sessions with MK801 treatment. Once the MWM assessment was completed, animals were administered 0.1 or 0.2mg/kg of MK801 and 1 or 3mg/kg of diazepam i.p., and tested for locomotor activity. Both groups, the CPF dietary and control, displayed analogous performance in motor activity. In conclusion, our data point to a connection between the long-term spatial memory, thigmotaxic response and CPF long after the exposure ended. Copyright © 2015 Elsevier Inc. All rights reserved.

    Full Text Available Background: This study aimed to determine whether motivational interviewing (MI could change dietary habit and body mass index (BMI in obese/overweight women. Methods: A cluster-randomized controlled study was performed in four health centers in Qazvin, central Iran. In total, 327 obese/overweight women were selected by a multi-stage sampling method and randomly assigned into control and experimental groups. Food frequency (using questionnaire; FFQ, BMI, and metabolic markers including blood pressure, total serum cholesterol and fasting blood glucose levels were measured in all participants. Data were collected twice (before and one year after the MI interventions. Data were analyzed using student t-test, and Stepwise Linear Regression. Results: There was a significant increase in daily consumption of dietary fiber, whole grain products, fruits and vegetables in the MI group (P<0.05. The consumption of meat product, total fat, saturated fat, carbohydrate and total energy intake were also significantly reduced after MI intervention (P<0.05. As a result, body weight and BMI were significantly reduced in the intervention group compared to the control group (P<0.05. Conclusion: MI is suggested to be an effective strategy to change life style and reduce BMI in overweight/obese women in the long term. This effect needs to be further investigated in different gender and age populations.

    Full Text Available Dietary folic acid deficiency induced early hearing loss in C57BL/6J mice after two-months, corroborating the epidemiological association previously described between vitamin deficiency and this sensory impairment. However, this strain is prone to early hearing loss, and hence we decided to analyze whether the effects exerted by folate deprivation follow the same pattern in a mouse strain such as CBA/Ca, which is resistant to hearing impairment. Here, we show results of a long-term study on hearing carried out on CBA/Ca mice subjected to dietary folate deprivation. Systemic changes included decreased serum folate levels, hyperhomocysteinemia and signs of anemia in the group fed the folate-deficient diet. Initial signs of hearing loss were detected in this strain after 8-months of vitamin deficiency, and correlated with histological damage in the cochleae. In conclusion, the data presented reinforce the importance of adequate folic acid levels for the auditory system and suggest that the impact of dietary deficiencies may depend on the genetic background.

    Objective To assess the long term effects of advice to restrict dietary sodium in adults with and without hypertension. Design Systematic review and meta-analysis of randomised controlled trials. Data sources Cochrane library, Medline, Embase, and bibliographies. Study selection Unconfounded randomised trials that aimed to reduce sodium intake in healthy adults over at least 6 months. Inclusion decisions, validity and data extraction were duplicated. Random effects meta-analysis, subgrouping, sensitivity analysis, and meta-regression were performed. Outcomes Mortality, cardiovascular events, blood pressure, urinary sodium excretion, quality of life, and use of antihypertensive drugs. Results Three trials in normotensive people (n=2326), five trials in those with untreated hypertension (n=387), and three trials in people being treated for hypertension (n=801) were included, with follow up from six months to seven years. The large high quality (and therefore most informative) studies used intensive behavioural interventions. Deaths and cardiovascular events were inconsistently defined and reported. There were 17 deaths, equally distributed between intervention and control groups. Systolic and diastolic blood pressures were reduced (systolic by 1.1 mm Hg, 95% confidence interval 1.8 to 0.4 mm Hg; diastolic by 0.6 mm Hg, 1.5 to −0.3 mm Hg) at 13 to 60 months, as was urinary 24 hour sodium excretion (by 35.5 mmol/24 hours, 47.2 to 23.9). Degree of reduction in sodium intake and change in blood pressure were not related. Conclusions Intensive interventions, unsuited to primary care or population prevention programmes, provide only small reductions in blood pressure and sodium excretion, and effects on deaths and cardiovascular events are unclear. Advice to reduce sodium intake may help people on antihypertensive drugs to stop their medication while maintaining good blood pressure control. What is already known on this topicRestricting sodium intake in people with

    Increased intake of dietary fiber has been proposed to reduce the risk of inflammatory bowel disease (Crohn's disease [CD] and ulcerative colitis [UC]). However, few prospective studies have examined associations between long-term intake of dietary fiber and risk of incident CD or UC. We collected and analyzed data from 170,776 women, followed up over 26 years, who participated in the Nurses' Health Study, followed up for 3,317,425 person-years. Dietary information was prospectively ascertained via administration of a validated semiquantitative food frequency questionnaire every 4 years. Self-reported CD and UC were confirmed through review of medical records. Cox proportional hazards models, adjusting for potential confounders, were used to calculate hazard ratios (HRs). We confirmed 269 incident cases of CD (incidence, 8/100,000 person-years) and 338 cases of UC (incidence, 10/100,000 person-years). Compared with the lowest quintile of energy-adjusted cumulative average intake of dietary fiber, intake of the highest quintile (median of 24.3 g/day) was associated with a 40% reduction in risk of CD (multivariate HR for CD, 0.59; 95% confidence interval, 0.39-0.90). This apparent reduction appeared to be greatest for fiber derived from fruits; fiber from cereals, whole grains, or legumes did not modify risk. In contrast, neither total intake of dietary fiber (multivariate HR, 0.82; 95% confidence interval, 0.58-1.17) nor intake of fiber from specific sources appeared to be significantly associated with risk of UC. Based on data from the Nurses' Health Study, long-term intake of dietary fiber, particularly from fruit, is associated with lower risk of CD but not UC. Further studies are needed to determine the mechanisms that mediate this association. Copyright © 2013 AGA Institute. Published by Elsevier Inc. All rights reserved.

    Although the composition of the gut microbiota is of interest, the functionality, or metabolic activity, of the gut microbiota is of equal importance: the gut microbiota can produce either harmful metabolites associated with human disease or beneficial metabolites that protect against disease. The purposes of this study were to determine the associations between dietary intake variables and fecal short and branched chain fatty acid (S/BCFA) concentrations; to determine the associations between dietary intake variables and inulin degradation, short and branched chain fatty acid (S/BCFA) production, and ammonia production during in vitro fecal fermentation of a highly fermentable substrate (inulin); and finally to compare results from the fermentation of inulin with those obtained in a previous report using a poorly fermentable substrate (whole wheat; Yang and Rose, Nutr. Res., 2014, 34, 749-759). Stool samples from eighteen individuals that had completed one-year dietary records were used in an in vitro fecal fermentation system with long-chain inulin as substrate. Few dietary intake variables were correlated with fecal S/BCFA concentrations; however, intakes of several plant-based foods, especially whole grain, dry beans, and certain vegetables that provided dietary fiber, plant protein, and B vitamins, were associated with acetate, propionate, butyrate, and total SCFA production during inulin fermentation. In contrast, intake of dairy and processed meats that provided cholesterol and little fiber, were associated with ammonia and BCFA production. Comparing results between inulin and whole wheat fermentations, significant correlations were only found for butyrate and BCFA, suggesting that regardless of the type of carbohydrate provided to the microbiota, long-term diet may have a pronounced effect on the propensity of the gut microbiota toward either beneficial metabolism (butyrate production) or detrimental metabolism (BCFA production). These results may help in

    During adolescence, young people are in a sensitive transition period when they gradually take over the responsibility for their own eating habits, health attitudes and behaviours and create lifelong habits so it is essential that they adopt healthy habits according to dietary recommendations. Knowledge is one of the factors necessary for the changes in dietary habits. The'objective of this study was to gain insight in nutritional knowledge and dietary habits of adolescents. The sample included 117 adolescents aged 17-19 years. Self-administered, anonymous questionnaire, representing modified version of General Nutrition Knowledge Questionnaire was used to assess general characteristics, nutritional knowledge about nutrients, dietary recommendations, sources of nutrients, diet-disease relationship, and dietary habits. Less than one third of adolescents showed satisfactory knowledge, but boys, adolescents from rural environment and overweight adolescents showed significantly lower knowledge unlike others. Meal skipping was present habit, especially for breakfast consumption. Especially high consumption of meat and meat products was noted for boys, while fruit and vegetables for girls. Fad dieting was quite practiced habit, especially in girls and overweight adolescents. Among girls, high consumption of sweets was confirmed, while boys showed high consumption of soft drinks. Television presents the main source of infor- mation about nutrition for adolescents. Collected data shows similarity with other research in Europe and North America that confirm strong influence of globalization and fast spread of unhealthy habits. The results pointed out weak spots in nutritional knowledge and revealed unhealthy eating habits. This information is necessary for the development of new approaches to modulate their knowledge and consequently act on their behaviour. Behavioral changes would include higher number of meals per day, regular breakfast consumption, higher intake of fish

    Studies that examined dietary energy requirements (DERs) of patients undergoing maintenance hemodialysis (MHD) have shown mixed results. Many studies reported normal DERs, but some described increased energy needs. DERs in MHD patients have been estimated primarily from indirect calorimetry and from nitrogen balance studies. The present study measured DERs in MHD patients on the basis of their dietary energy intake and changes in body composition. This study assessed DERs in MHD patients who received a constant energy intake while changes in their body composition were measured. Seven male and 6 female sedentary, clinically stable MHD patients received a constant mean (±SD) energy intake for 92.2 ± 7.9 d while residing in a metabolic research ward. Changes in fat and fat-free mass, measured by dual-energy X-ray absorptiometry, were converted to calorie equivalents and added to energy intake to calculate energy requirements. The average DER was 31 ± 3 kcal · kg(-1) · d(-1) calculated from energy intake and change in fat and fat-free calories, which was 28 ± 197 kcal/d over the 92 d of the study. DERs of MHD patients correlated strongly with their body weight (r = 0.81, P = 0.002) and less closely with their measured resting energy expenditure expressed as kcal/d (r = 0.69, P = 0.01). Although the average observed DER in MHD patients was similar to published estimated values for normal sedentary individuals of similar age and sex, there was wide variability in DER among individual patients (range: 26-36 kcal · kg(-1) · d(-1)). Average DERs of sedentary, clinically stable patients receiving MHD are similar to those of sedentary normal individuals. Our data do not support the theory that MHD patients have increased DERs. Due to the high variability in DERs, careful monitoring of the nutritional status of individual MHD patients is essential.

  11. Long-term declines in dietary nutritional quality for North American cattle

    2017-04-01

    With over 1 billion cattle in the world as well as over 2 billion sheep, goats and buffalo, these animals contribute approximately 15% of the global human protein supply while producing a significant proportion of anthropogenic emissions of greenhouse gases and global nutrient fluxes. Despite increasing reliance on grazers for protein production globally, the future of grazers in a changing world is uncertain. Factors such as increased prevalence of drought, rising atmospheric CO2 concentrations, and sustained nutrient export all have the potential to reduce cattle performance by reducing the nutritional quality of forage. However, there are no analyses to quantify changes in diet quality, subsequent impact on cattle performance and cost of supplementation necessary to mitigate any predicted protein deficiency. To quantify the trajectory of nutritional stress in cattle, we examined more than 36 000 measurements of dietary quality taken over 22 yr for US cattle. Here, we show that standardizing for spatial and temporal variation in drought and its effects on forage quality, cattle have been becoming increasingly stressed for protein over the past two decades, likely reducing cattle weight gain. In economic terms, the replacement costs of reduced protein provision to US cattle are estimated to be the equivalent of 1.9 billion annually. Given these trends, nitrogen enrichment of grasslands might be necessary if further reduction in protein content of forages is to be prevented.

Therefore, insight in the accumulation of PCBs in the food chain is required. Until now, the maximally admitted PCB content in Belgian animal feeds and products, based on the sum of 7 reference PCB congeners, amounts to 200 ng/g fat. The present study with laying hens was designed to examine the long-term effects of low level dietary PCB contents on animal performance, egg quality, apparent PCB digestibility, PCB retention and PCB incorporation in egg yolk, abdominal adipose tissue, thigh and breast muscle tissues. Moreover, the effect of low dietary amounts of added fat, varying between 1.5% and 4.5%, on PCB digestibility and incorporation in laying hens was investigated. Also we addressed the question whether PCB incorporation in egg yolk as well as in adipose and muscle tissue would meet the current standard of 200 ng/g fat.

    Arginase II is a mitochondrial enzyme that catalyses the hydrolysis of L-arginine into urea and ornithine. It is presentin other extra-hepatic tissues that lack urea cycle. Therefore, it is plausible that arginase II has a physiological roleother than urea cycle which includes polyamine, proline, glutamate synthesis and regulation of nitric oxide production.The high expression of arginase II in kidney, among extrahepatic tissues, might have an important role associatedwith kidney functions. The present study is aimed to determine the age-associated alteration in the activity andexpression of arginase II in the kidney of mice of different ages. The effect of dietary restriction to modulate the agedependentchanges of arginase II was also studied. Results showed that renal arginase II activity declines significantlywith the progression of age (p<0.01 and p<0.001 in 6- and 18-month-old mice, respectively as compared to 2-monthold mice) and is due to the reduction in its protein as well as the mRNA level (p<0.001 in both 6- and 18-month-oldmice as compared to 2-month-old mice). Long-term dietary restriction for three months has significantly up-regulatedarginase II activity and expression level in both 2- and 18-month-old mice (p<0.01 and p<0.001, respectively ascompared to AL group). These findings clearly indicate that the reducing level of arginase II during aging might havean impact on the declining renal functions. This age-dependent down-regulation of arginase II in the kidney can beattenuated by dietary restriction which may help in the maintenance of such functions.

    Full Text Available The aim of this study was to assess the influence of long-term fat supplementation on the fatty acid profile of heavy pig adipose tissue. Fifty-four Large White barrows, averaging 25 kg LW, were randomized (matched weights to one of three isoenergetic diets supplemented with either tallow (TA, maize oil (MO, or rapeseed oil (RO. The fats were supplement- ed at 3% as fed from 25 to 110 kg LW, and at 2.5 % from 110 kg to slaughtering. Following slaughter at about 160 kg LW, backfat samples were collected from ten animals per treatment and analyzed. Fatty acid composition of backfat close- ly reflected the fatty acid composition of the supplemented fats. The backfat of pigs fed TA had the highest saturated fatty acid content (SFA (P<0.01; those fed MO had the highest content in polyunsaturated fatty acid (PUFA and the lowest in monounsaturated fatty acid (MUFA content; those fed RO had the highest content of linolenic acid (C18:3 and cis 11- ecosenoic acid (C20:1. Only MO treatment had an effect on linoleic acid levels and the iodine value (IV of backfat, result- ing in levels higher than those (IV = 70; C18:2 = 15% accepted by the Parma Consortium for dry-cured ham. The IV and unsaturation index in both layers of subcutaneous backfat tissue differed significantly between treatments. These results show that long-term dietary supplementation with different fats changes the fatty acid profile of heavy pig adipose tissue. Supplementation with rapeseed oil increases the proportion of “healthy” fatty acids in pig fat, thereby improving the nutritional quality, however the effects on the technological quality of the fat must be carefully assessed.

    This presentation will discuss the International Space Station s (ISS) Regenerative Environmental Control and Life Support System (ECLSS) operations with discussion of the on-orbit lessons learned, specifically regarding the challenges that have been faced as the system has expanded with a growing ISS crew. Over the 10 year history of the ISS, there have been numerous challenges, failures, and triumphs in the quest to keep the crew alive and comfortable. Successful operation of the ECLSS not only requires maintenance of the hardware, but also management of the station resources in case of hardware failure or missed re-supply. This involves effective communication between the primary International Partners (NASA and Roskosmos) and the secondary partners (JAXA and ESA) in order to keep a reserve of the contingency consumables and allow for re-supply of failed hardware. The ISS ECLSS utilizes consumables storage for contingency usage as well as longer-term regenerative systems, which allow for conservation of the expensive resources brought up by re-supply vehicles. This long-term hardware, and the interactions with software, was a challenge for Systems Engineers when they were designed and require multiple operational workarounds in order to function continuously. On a day-to-day basis, the ECLSS provides big challenges to the on console controllers. Main challenges involve the utilization of the resources that have been brought up by the visiting vehicles prior to undocking, balance of contributions between the International Partners for both systems and resources, and maintaining balance between the many interdependent systems, which includes providing the resources they need when they need it. The current biggest challenge for ECLSS is the Regenerative ECLSS system, which continuously recycles urine and condensate water into drinking water and oxygen. These systems were brought to full functionality on STS-126 (ULF-2) mission. Through system failures and recovery

    The aim of this study was to evaluate the influence of a diet and the feeding method on caries intensity among children aged 36-48 months. Dental examination was carried out in 255 children and their mothers were asked about child's dietary habits. The population checked was divided into three groups: with dmf = 0, dmf 1-3 and dmf > or = 4. Statistically significant correlation between caries intensity and bottle feeding during sleep and frequency of eating cariogenic food were shown. Parents of young children should be educated about the influence of dietary habits on dental condition.

    Lifestyle plays an important role in the development of obesity during childhood and adolescence. We provide up-to-date information about the relationship between obesity and food intake and dietary patterns in adolescents. Scientific evidence is increasing about the dietary factors associated with this relationship, specifically a low meal frequency, skipping breakfast, and a high consumption of sugar sweetened beverages. Maybe some of the reviewed dietary factors could cluster in the same population of adolescents, increasing the individual risk. There is little information about dietary patterns and current time trends in adolescents; however, the available data seem to show that the tendency in the adolescent population worldwide is to increase those dietary factors related with obesity development. Public health efforts should be emphasized in order to decrease the current tendency. Regular family meals could serve as role models for healthy eating behaviors. Educational intervention programs for parents, aiming to modify the healthfulness of the diet, seems to be one of the most adequate tools to deal with the worldwide obesity epidemic.

    This study was conducted to evaluate the effects of dietary restriction on oxidative status and sperm parameters in rats exposed to long-term heat stress. Forty healthy Sprague-Dawley rats, aged 2.5 month, were divided into four groups of 10 with respect to feeding and temperature regimen (room temperature (22 °C)-ad libitum, room temperature-dietary restriction (40%), high temperature (38 °C)-ad libitum, high temperature-dietary restriction). At the end of the 9th week, some oxidants (lipid hydroperoxide, total oxidant status, oxidative stress index) and antioxidants (total antioxidant status, sulfhydryl groups, ceruloplasmin, paraoxonase and arylesterase activities) were measured in the testis tissue. The concentration, motility, volume, abnormal sperm count, acrosome and membrane integrity of epididymal spermatozoon and intratesticular testosterone levels were evaluated. High temperature did not change oxidative and antioxidative parameters except for sulfhydryl groups and ceruloplasmin, yet it impaired all sperm values. Neither sperm values nor oxidative status apart from sulfhydryl groups, ceruloplasmin and arylesterase was affected by dietary restriction in the testis tissue. These results suggest that long-term heat stress does not have a significant effect on testicular oxidative status, while the spermatozoa are sensitive to heat stress in young rats. Dietary restriction failed to improve the sperm quality and oxidative status except some individual antioxidant parameters; conversely, it decreased intratesticular testosterone level in the young rats exposed to long-term heat stress.

    Background: In view of evidence linking pericardial fat accumulation with increased cardiovascular disease risk, strategies to reduce its burden are needed. Data comparing the effects of specific long-term dietary interventions on pericardial fat tissue mobilization are sparse.Objective: We sought to evaluate intrapericardial-fat (IPF) and extrapericardial-fat (EPF) changes during weight-loss interventions by different dietary regimens.Design: During 18 mo of a randomized controlled trial, we compared a Mediterranean/low-carbohydrate (MED/LC) diet plus 28 g walnuts/d with a calorically equal low-fat (LF) diet among randomly assigned participants with moderate abdominal obesity. We performed whole-body MRI and volumetrically quantified IPF and EPF among 80 participants to follow the 18-mo changes.Results: The participants [mean age: 48.6 y; mean body mass index (BMI; in kg/m(2)); 31.7; 90% men] had baseline IPF and EPF (mean ± SD) volumes of 172.4 ± 53.3 mL and 194.9 ± 71.5 mL, respectively. The 18-mo moderate weight loss of 3.7 kg was similar in both groups, but the reduction in waist circumference was higher in the MED/LC group (-6.9 ± 6.6 cm) than in the LF diet group (-2.3 ± 6.5 cm; P = 0.01). After 18 mo, the IPF volume had reduced twice as much in the MED/LC group compared with the LF group [-37 ± 26.2 mL (-22% ± 15%) compared with -15.5 ± 26.2 mL (-8% ± 15%), respectively; P 0.1]. After controlling for weight loss, IPF and EPF volume reduction paralleled changes in lipid profile but not with improved glycemic profile variables: the IPF relative reduction was associated with a decrease in triglycerides (TGs) (β = 0.090; 95% CI: 0.026, 0.154; P = 0.007) and the ratio of TGs to high-density lipoprotein (HDL) cholesterol (β = 2.689; 95% CI: 0.373, 5.003; P = 0.024), and the EPF relative reduction was associated with an increase in HDL cholesterol (β = -0.452; 95% CI: -0.880, -0.023; P = 0.039) and a decrease in total cholesterol and HDL cholesterol (

    Acne vulgaris is a common disease affecting adolescents. There is not comprehensive data on acne prevalence in the Central Anatolia Region in particular. Etiology of acne is not clarified yet. Acne might be related to environmental factors. There is increasing evidence supporting acne and diet relationship. The aim of the study was to determine the acne prevalence in adolescents in the city of Eskisehir, located in the Central Anatolia, Turkey in addition to evaluate factors affecting acne and its relationship with dietary habits. A cross-sectional study was conducted on 2300 participants aged 13-18 years. The participants were asked to complete a questionnaire form consisting information about acne and a questionnaire form consisting information about dietary habits (The Adolescent Food Habits Checklist). In addition an objective evaluation of acne was determined. The mean age of students with acne was 15.10±1.53. The current acne prevalence was 60.7%. Although 21% of the participants had severe acne (grade 3-4) and 25% developed sequelaes, only 11.5% of all participants consulted a doctor. The participants without acne had healthier dietary habits than participants with acne (Pacne. Acne prevalence is high among adolescents in Eskisehir but the rate of consulting doctor is low. Increasing public awareness is critical for convincing adolescents to seek medical help earlier. Acne was related with dietary habits. Fat, sugar and fast food consumption is found to be positively correlated with acne prevalence. © 2011 The Authors.

    Data are limited as to whether participants in diet trials truly adhere to their assigned diet and the factors that affect their adherence. We evaluated success and adherence in a two-year dietary intervention randomized controlled trial (DIRECT) in which 322 moderately obese participants (mean age 52 yrs, mean body-mass-index (BMI) 31 kg/m(2), 86% men) were randomized to one of three groups: low-fat, Mediterranean, or low-carbohydrate diets. Overall compliance at month-24 was 85%, with 90% in low-fat, 85% in Mediterranean, and 78% in low-carbohydrate diet (p = .042 between groups). Attrition was higher in women (29% vs. 14% men, p = .001) and current smokers (25% vs. 14% among maintainers, p = 0.04). In a multivariate model, independent predictors of dropping-out were: higher baseline BMI (OR = 1.11; CI: 1.03-1.21) and less weight loss at month-6 (OR = 1.20; CI: 1.1-1.3). In a multivariate model, greater weight loss achieved at month-6 was the main predictor associated with success in weight loss (> 5%) over 2 years (OR = 1.5; CI: 1.35-1.67). Self-reported complete adherence score to diet was greater on low-carbohydrate diet (p low-fat) until month-6, but dropped overall from 81% at month-1 to 57% at month-24. Holidays were a trigger to a significant decrease in adherence followed by a partial rebound. Changes in diet composition from month-1 to month-12 were more pronounced in the multi-stage low-carbohydrate diet-group (p < .05). Generally, the most irresistible restricted food items were cookies (45% of dieters) and fruits (30%). Among the physically active (n = 107), 44% reported a tendency to eat less after exercising compared to 10% who tended to eat more. Initial 6-month reduction in weight is the main predictor of both long-term retention and success in weight loss. Special attention is needed for women, current smokers, and during holidays. Physical activity is associated with subsequent reduction in energy intake.

    Full Text Available Abstract Background Weight loss in overweight or obese breast cancer patients is associated with an improved prognosis for long term survival. However, it is not clear whether the macronutrient composition of the chosen weight loss dietary plan imparts further prognostic benefit. A study protocol is presented for a dietary intervention to investigate the effects of weight loss dietary patterns that vary markedly in fat and carbohydrate contents on biomarkers of exposure to metabolic processes that may promote tumorigenesis and that are predictive of long term survival. The study will also determine how much weight must be lost for biomarkers to change in a favorable direction. Methods/Design Approximately 370 overweight or obese postmenopausal breast cancer survivors (body mass index: 25.0 to 34.9 kg/m2 will be accrued and assigned to one of two weight loss intervention programs or a non-intervention control group. The dietary intervention is implemented in a free living population to test the two extremes of popular weight loss dietary patterns: a high carbohydrate, low fat diet versus a low carbohydrate, high fat diet. The effects of these dietary patterns on biomarkers for glucose homeostasis, chronic inflammation, cellular oxidation, and steroid sex hormone metabolism will be measured. Participants will attend 3 screening and dietary education visits, and 7 monthly one-on-one dietary counseling and clinical data measurement visits in addition to 5 group visits in the intervention arms. Participants in the control arm will attend two clinical data measurement visits at baseline and 6 months. The primary outcome is high sensitivity C-reactive protein. Secondary outcomes include interleukin-6, tumor necrosis factor-α, insulin-like growth factor-1 (IGF, IGF binding protein-3, 8-isoprostane-F2-alpha, estrone, estradiol, progesterone, sex hormone binding globulin, adiponectin, and leptin.

    Full Text Available Abstract Background Serum selenium level (s-Se has been associated with prostate cancer (PrCa risk. We investigated the relation between s-Se, smoking and non-screening detected PrCa and explored if polymorphisms in two DNA repair genes: OGG1 and MnSOD, influenced any effect of s-Se. Methods ULSAM, a population based Swedish male cohort (n = 2322 investigated at age 50 for s-Se and s-Se influencing factors: serum cholesterol, erythrocyte sedimentation rate and smoking habits. At age 71 a subcohort, (n = 1005 was genotyped for OGG1 and MnSOD polymorphisms. Results In a 34-year-follow-up, national registries identified 208 PrCa cases further confirmed in medical records. Participants with s-Se in the upper tertile had a non-significantly lower risk of PrCa. Smokers with s-Se in the two lower tertiles (≤80 μg/L experienced a higher cumulative incidence of PrCa than smokers in the high selenium tertile (Hazard Ratio 2.39; 95% CI: 1.09-5.25. A high tertile selenium level in combination with non-wt rs125701 of the OGG1 gene in combination with smoking status or rs4880 related variation of MnSOD gene appeared to protect from PrCa. Conclusions S-Se levels and smoking habits influence long-term risk of PrCa. Smoking as a risk factor for PrCa in men with low s-Se is relevant to explore further. Exploratory analyses of variations in OGG1 and MnSOD genes indicate that hypotheses about patterns of exposure to selenium and smoking combined with data on genetic variation in genes involved in DNA repair can be valuable to pursue.

    Long-term dietary exposures to lead in young children were calculated by combining food consumption data of 11 European countries categorised using harmonised broad food categories with occurrence data on lead from different Member States (pan-European approach). The results of the assessment...... in children living in the Netherlands were compared with a long-term lead intake assessment in the same group using Dutch lead concentration data and linking the consumption and concentration data at the highest possible level of detail. Exposures obtained with the pan-European approach were higher than...... the national exposure calculations. For both assessments cereals contributed most to the exposure. The lower dietary exposure in the national study was due to the use of lower lead concentrations and a more optimal linkage of food consumption and concentration data. When a pan-European approach, using...

    Full Text Available A rabbit model of Alzheimer’s disease based on feeding a cholesterol diet for eight weeks shows sixteen hallmarks of the disease, including learning and memory changes. Although we have shown 2% cholesterol and copper in water can retard learning, other studies show feeding dietary cholesterol before learning can improve acquisition whereas feeding cholesterol after learning can degrade long-term memory. We explored this issue by manipulating cholesterol concentration and duration following classical trace conditioning of the rabbit’s nictitating membrane response and assessed conditioned responding after eight weeks on cholesterol. First, rabbits given trace classical conditioning followed by 0.5%, 1%, or 2% cholesterol for eight weeks showed body weight and serum cholesterol levels that were a function of dietary cholesterol. Although all concentrations of cholesterol showed some sign of retarding long-term memory, the level of memory retardation was correlated with serum cholesterol levels. Second, rabbits given trace conditioning followed by different durations of a 2% cholesterol diet combined with different durations of a 0% control diet for 8 weeks showed duration and timing of a 2% cholesterol diet were important in affecting recall. The data support the idea that dietary cholesterol may retard long-term memory.

    Aging may coincide with a declining gustatory function that can affect dietary intake and ultimately have negative health consequences. Taste loss is caused by physiological changes and worsened by events often associated with aging, such as polypharmacy and chronic disease. The most pronounced increase in elderly people's detection threshold has been observed for sour and bitter tastes, but their perception of salty, sweet, and umami tastes also seems to decline with age. It has often been suggested that elderly people who lose their sense of taste may eat less food or choose stronger flavors, but the literature has revealed a more complicated picture: taste loss does not appear to make elderly people prefer stronger flavors, but nutrition surveys have pointed to a greater consumption of sweet and salty foods. Real-life eating habits thus seem to be more influenced by other, social and psychological factors. Elderly gustatory function is worth investigating to identify dietary strategies that can prevent the consequences of unhealthy eating habits in the elderly. This paper discusses age-related changes in taste perception, focusing on their consequences on food preferences, and pointing to some strategies for preserving appropriate dietary habits in elderly people.

    Nonalcoholic fatty liver disease (NAFLD) is one of the most frequent causes of health problems in Western (industrialized) countries. Moreover, the incidence of infantile NAFLD is increasing, with some of these patients progressing to nonalcoholic steatohepatitis. These trends depend on dietary habits and life-style. In particular, overeating and its associated obesity affect the development of NAFLD. Nutritional problems in patients with NAFLD include excess intake of energy, carbohydrates, and lipids, and shortages of polyunsaturated fatty acids, vitamins, and minerals. Although nutritional therapeutic approaches are required for prophylaxis and treatment of NAFLD, continuous nutrition therapy is difficult for many patients because of their dietary habits and lifestyle, and because the motivation for treatment differs among patients. Thus, it is necessary to assess the nutritional background and to identify nutritional problems in each patient with NAFLD. When assessing dietary habits, it is important to individually evaluate those that are consumed excessively or insufficiently, as well as inappropriate eating behaviors. Successful nutrition therapy requires patient education, based on assessments of individual nutrients, and continuing the treatment. In this article, we update knowledge about NAFLD, review the important aspects of nutritional assessment targeting treatment success, and present some concrete nutritional care plans which can be applied generally.

    Full Text Available Abstract Background Previous research has shown that internet education can lead to short-term improvements in clinicians' knowledge, confidence and communication practices. We wished to better understand the duration of these improvements and whether different curriculum delivery strategies differed in affecting these improvements. Methods As previously described, we conducted a randomized control trial comparing four different strategies for delivering an e-curriculum about herbs and other dietary supplements (HDS to clinicians. The four strategies were delivering the curriculum by: a email over 10 weeks; b email within one week; c web-site over 10 weeks; d web-site within one week. Participants were surveyed at baseline, immediately after the course and 6–10 months after completing the course (long-term. Long-term outcomes focused on clinicians' knowledge, confidence and communication practices. Results Of the 780 clinicians who completed the course, 385 (49% completed the long-term survey. Completers and non-completers of the long-term survey had similar demographics and professional characteristics at baseline. There were statistically significant improvements from baseline to long-term follow-up in knowledge, confidence and communication practices; these improvements did not differ by curriculum delivery strategy. Knowledge scores improved from 67.7 ± 10.3 at baseline to 78.8 ± 12.3 at long-term follow-up (P Conclusion This e- curriculum led to significant and sustained improvements in clinicians' expertise about HDS regardless of the delivery strategy. Future studies should compare the impact of required vs. elective courses and self-reported vs. objective measures of behavior change.

    Diet influences gut microbiota composition. Therefore, we hypothesized that diet would impact the extent of dietary fiber utilization and the types of metabolic end-products produced by the microbiota during in vitro fecal fermentation. By obtaining long-term dietary records from fecal donors, we aimed to determine the correlations between dietary intake variables and dietary fiber degradation and short-/branched-chain fatty acid (BCFA) and ammonia production during in vitro fecal fermentation. Eighteen subjects completed 1-year diet history questionnaires and provided fecal samples that were used for in vitro fermentation of a whole wheat substrate. The percentage of dietary fiber fermented was not correlated with nutrient intakes; however, butyrate production was correlated with fecal donor intake of many nutrients of which principal component analysis revealed were mostly contributed by grain-, nut-, and vegetable-based foods. Negative correlations were found for propionate with intake of total carbohydrate, added sugar, and sucrose and for ammonia and BCFA production with intake of unsaturated fats. Thus, our analysis did not support our first hypothesis: the percentage of dietary fiber fermented during in vitro fermentation was not correlated with dietary records. However, production of butyrate; BCFA; ammonia; and, to a lesser extent, propionate was correlated with the diet records of fecal donors, thus supporting our second hypothesis. These results suggest that diets high in plant-based foods and high in unsaturated fats are associated with microbial metabolism that is consistent with host health.

    Full Text Available Changes in dietary habits and lifestyle are considered the main factors associated with several diet-related diseases in the Arab Gulf countries. The aim of this study was, therefore, to describe the dietary and lifestyle habits amongst adolescents in Bahrain. A cross-sectional study was carried out amongst male and female secondary school students selected using the multi-stage stratified random sampling technique. A sample size of 735 subjects (339 males and 396 females, aged 15–18 years, was selected from government schools from all the governorates of Bahrain. Skipping breakfast was significantly greater in females (62.8% compared to males (37.2%, (P<0.01. About 88% of adolescents snacked during school break, 70.7% procuring food from the school canteen. Fruit was not consumed by about 27.7% of respondents (33.5% males, 66.5% females and the gender difference was statistically significant (P<0.01. Fish and lentils were less preferred, while chicken was more popular. There was no significant difference between gender and frequency of eating fast food. About 8.4% of respondents reported not eating burgers, with 68.8% preferring regular size burgers. Furthermore, 24.4% preferred large portions of potato chips (53.1% male, 46.9% female. About 29.8% watched TV for more than 5 hours a day (51.2% females, 48.8% males. About 69% of males practiced sports everyday as against 30.8% of females (P<0.01 and 81.6% of those who participated in sport activity outside school were males compared to 18.4% of females. It seems that the adolescents in Bahrain are moving toward unhealthy dietary habits and lifestyles, which in turn will affect their health status in the future. Promoting healthy lifestyle and eating habits should be given a priority in school health programs.

    Background & Aims Increased intake of dietary fiber has been proposed to reduce risk of inflammatory bowel diseases (Crohn’s disease [CD], ulcerative colitis [UC]). However, few prospective studies have examined associations between long-term intake of dietary fiber and risk of incident CD or UC. Methods We collected and analyzed data from 170,776 women, followed over 26 y, who participated in the Nurses’ Health Study, followed for 3,317,425 person-y. Dietary information was prospectively ascertained via administration of a validated semi-quantitative food frequency questionnaire every 4 y. Self-reported CD and UC were confirmed through review of medical records. Cox proportional hazards models, adjusting for potential confounders, were used to calculate hazard ratios (HRs). Results We confirmed 269 incident cases of CD (incidence 8/100,000 person-y) and 338 cases of UC (incidence 10/100,000 person-y). Compared to the lowest quintile of energy-adjusted cumulative average intake of dietary fiber, intake of the highest quintile (median of 24.3 g/day) was associated with a 40% reduction in risk of CD (multivariate HR for CD, 0.59; 95% confidence interval [CI], 0.39–0.90). This apparent reduction appeared to be greatest for fiber derived from fruits; fiber from cereals, whole grains, or legumes did not modify risk. In contrast, neither total intake of dietary fiber (multivariate HR, 0.82; 95% CI 0.58–1.17) nor intake of fiber from specific sources appeared to be significantly associated with risk of UC. Conclusion Based on data from the Nurses’ Health Study, long-term intake of dietary fiber, particularly from fruit, is associated with lower risk of CD but not UC. Further studies are needed to determine the mechanisms that mediate this association. PMID:23912083

    The phenotype of polycystic ovarian syndrome (PCOS) is known to worsen with weight gain, increased ingestion of carbohydrates and a sedentary lifestyle. The purpose of this study was to assess the dietary habits in a group of adolescent girls with PCOS. Adolescents with PCOS were recruited and asked to complete a questionnaire on their eating habits and a recall dietary diary, from which their caloric and macronutrient intake was calculated. Results were compared with those from a group of normal controls. Thirty-five women with PCOS and 46 controls were included. Girls with PCOS were less likely to have cereals for breakfast (20.7 versus 66.7%) and as a result consumed less fibre than controls. They were more likely to eat an evening meal (97.1 versus 78.3%) and eat this over an hour later when compared to controls. Despite having comparable body mass indexes, girls with PCOS ate a daily surplus calorie average of 3% versus controls that had a negative calorie intake of 0.72% (p = 0.047). Ameliorating eating habits early in adolescence in girls with PCOS may improve future metabolic concerns related to a genetic predisposition and worsened by an unhealthy lifestyle.

    The adequacy of a diet is usually evaluated based on nutrient intake. As people eat foods but not nutrients, food-based dietary guidelines (FBDG) are needed. To evaluate dietary habits in infants and young children, the following stepwise approach is suggested: (1) develop country-specific FBDG to identify the potential of common nonfortified foods to ensure adequate nutrient intake and (2) examine potential 'critical' dietary patterns if main food groups are excluded, such as in vegetarian diets or if a family's precarious social status leads to food constraints. The German FBDG for infant and child nutrition demonstrate that a well-designed mixture of common foods results in an adequate supply of nutrients, except for vitamin D, iodine and iron. The following solutions are feasible to address deficiencies in these critical nutrients: routine supplementation (vitamin D), fortified complementary food consumption or supplementation for infants as well as inclusion of table salt in the family diet for children (iodine), and individual pediatric care for infants at risk (iron). In the exclusion of food groups of animal origin from vegetarian diets, several nutrients are at risk of becoming deficient if not substituted. Existing studies characterizing vegetarian children are rare. These were mainly published in the 1980s and 1990s and were biased towards a high social status. Thus, firm conclusions on today's dietary practices and health statuses of European vegetarian children cannot be drawn. A social gradient exists for food patterns and dietary quality in children, but energy intake need not necessarily be affected. Scenarios in Germany suggest that families on unemployment assistance can afford to eat a diet compliant with German FBDG only if they restrict food selection to basic food. Yet, the question of how families cope with financial constraints in everyday life remains. In conclusion, well-designed FBDG provide various opportunities to identify critical

    Dietary supplementation with fish oil rich in n-3 polyunsaturated fatty acids has been suggested to protect the kidney against cyclosporin A (CsA) toxicity. This study investigated the effects of a 10-wk dietary supplementation with fish oil on renal function and renal functional reserve in healthy volunteers (N = 9) and two groups of stable long-term kidney-transplanted patients treated with maintenance low-dose CsA (3.0 +/- 0.6 mg/kg; N = 9) or without CsA (N = 9). After an overnight fast, the subjects were water loaded, and clearance studies were performed, postponing morning medication. GFR and effective RPF were measured as the renal clearances of (99mTc)DTPA and (131I)hippuran, respectively. Renal tubular function was evaluated by use of the renal clearance of lithium and the urinary excretion of beta 2-microglobulin. Fish oil did not change baseline values of effective RPF, GFR, lithium clearance, and urinary excretion of beta 2-microglobulin in any of the groups. The infusion of amino acids induced a comparable increase in GFR, lithium clearance, and the urinary excretion rate of beta 2-microglobulin in all three groups with no additional effect of fish oil. Thus, long-term renal transplant recipients treated with a low maintenance dose of CsA had a well-preserved renal functional reserve, and dietary supplementation with fish oil in these patients did not improve renal function.

    Past dietary patterns may be more important than recent dietary patterns in the aetiology of chronic diseases because of the long latency in their development. We developed an instrument to recall vegetarian dietary patterns during the lifetime and examined its reliability of recall over 5·3 and 32·6 years on average. The short-term/5-year recall ability study (5-RAS) was done using 24 690 participants from the cohort of the Adventist Health Study-2 (mean age 62·2 years). The long-term/33-year recall ability study (33-RAS) included an overlap population of 1721 individuals who joined the Adventist Health Study-1 and Adventist Health Study-2 (mean age 72·5 years). Spearman correlation coefficients for recall of vegetarian status were 0·78 and 0·72 for the 5-RAS and 33-RAS, respectively, when compared with 'reference' data. For both time periods sensitivity and positive predictive values were highest for the lacto-ovo-vegetarian and non-vegetarian patterns (vegans, lacto-ovo-vegetarians, pesco-vegetarians, semi-vegetarians and non-vegetarians). In the 5-RAS analyses, male, non-black, younger, and more educated participants, lifetime Adventists, and those with more stability of consumption of animal products generally showed higher recall ability. Somewhat similar tendencies were shown for the 33-RAS analyses. Our findings show that the instrument has higher reliability for recalled lacto-ovo-vegetarian and non-vegetarian than for vegan, semi- and pesco-vegetarian dietary patterns in both short- and long-term recalls. This is in part because these last dietary patterns were greatly contaminated by recalls that correctly would have belonged in the adjoining category that consumed more animal products.

    Study Goal was to determine dietary habits in school-aged children. Sampling of children was conducted in two stages. In the first stage, five schools in Nadzaladevi district of city Tbilisi were randomly selected. On the second stage the study groups from the appropriate school-aged students (10-14 years old children) were also randomly selected. All student participants filled out standardized and adopted questionnaires suggested by the American Academy of family physicians. Data were analyzed by using EpiInfo 7th version. Statistical analyses looked at correlations between criteria of unhealthy diet (such as morning without breakfast, frequent consumption of non-alcoholic beverages and fast food products) and overweight/obesity. A Body Mass Index (BMI) was calculated by using CDC tool. 175 children with ages of 10-14 years (47% boys) were included and interviewed. Half of the children noted that they love or like fast food products. 10% - visits fast food places 2-3 times a week together with a family. 11% - visits fast food places 5 times a week and even more. 34% - do not start morning with breakfast; 15% - eat only twice a day; 26% - add salt to their dishes; 58% - drink non-alcoholic beverages every day or many times during a week; 24% - are overweight; 29% suffer from obesity; 25% noted that fast food places are located near schools. Very weak correlation was found between unhealthy diet (morning without breakfast, frequent consumption of non-alcoholic beverages and fast food products) and overweight/obesity. According to study results, dietary habits of school-age children in Tbilisi is unhealthy; to improve nutritional habits is essential: (1) promote consumer (students, parents and teachers) awareness on a healthy diet, (2) educate children, adolescents and adults about nutrition and healthy dietary practices, (3) encourage to raise awareness about the salt consumption in recommended doses in children.

This study investigated the relationships between dietary habits and cardiometabolic health among obese children living in a city of Northern Italy. Methods: Dietary habits were collected in 448 obese subjects aged 6-18 years, attending an obesity outpatient center in Milan. Anthropometry, blood pressure (BP, lipids, fasting and post-load glucose, and insulin were measured. Physical activity was assessed in adolescents using a questionnaire. Results: Frequency of glucose intolerance, hypertension and dyslipidemia was 0.7%, 13% and 27.2%, respectively. Plausible reporters consumed more animal protein and sodium and less legumes than recommended in nutritional recommendations and adequate amounts of fiber mainly derived from whole grains. Subjects skipping breakfast had unhealthy diets and greater body fatness. After adjustment for confounders, waist/height and fasting glucose were associated with sodium intake (r =0.149 and r = 0.142, respectively; p Conclusions: The cardiometabolic health of obese children improves with vegetable protein and whole grain intake, whereas dysglycemia and adiposity increase with sodium intake.

    In two long-term feeding trials in seawater, Atlantic salmon were fed EPA+DHA in graded levels, from 1·3 to 7·4 % of fatty acids (FA, 4-24 g/kg feed) combined with approximately 10 % 18 : 3n-3, at 6 and 12°C. Dietary EPA appeared to be sufficient in all diet groups, as no differences were seen in polar lipid tissue concentrations of either the brain, retina or erythrocytes. For DHA, a reduction in tissue levels was observed with low dietary supply. Effects on brain DHA at ≤1·4 % EPA+DHA of dietary FA and retina DHA at ≤2·7 % EPA+DHA of dietary FA were only observed in fish reared at 6°C, suggesting an effect of temperature, whereas tissue levels of n-6 FA increased as a response to increased dietary n-6 FA in both the brain and the retina at both temperatures. DHA levels in erythrocytes were affected by ≤2·7 % EPA+DHA at both temperatures. Therefore, DHA appears to be the limiting n-3 FA in diets where EPA and DHA are present in the ratios found in fishmeal and fish oil. To assess the physiological significance of FA differences in erythrocytes, the osmotic resistance was tested, but it did not vary between dietary groups. In conclusion, ≤2·7 % EPA+DHA of FA (≤9 g/kg feed) is not sufficient to maintain tissue DHA status in important tissues of Atlantic salmon throughout the seawater production cycle despite the presence of dietary 18 : 3n-3, and effects may be more severe at low water temperatures.

    Full Text Available This systematic literature review examined the role of dietary macronutrient composition, food consumption and dietary patterns in predicting weight or waist circumference (WC change, with and without prior weight reduction. The literature search covered year 2000 and onwards. Prospective cohort studies, case–control studies and interventions were included. The studies had adult (18–70 y, mostly Caucasian participants. Out of a total of 1,517 abstracts, 119 full papers were identified as potentially relevant. After a careful scrutiny, 50 papers were quality graded as A (highest, B or C. Forty-three papers with grading A or B were included in evidence grading, which was done separately for all exposure-outcome combinations. The grade of evidence was classified as convincing, probable, suggestive or no conclusion. We found probable evidence for high intake of dietary fibre and nuts predicting less weight gain, and for high intake of meat in predicting more weight gain. Suggestive evidence was found for a protective role against increasing weight from whole grains, cereal fibre, high-fat dairy products and high scores in an index describing a prudent dietary pattern. Likewise, there was suggestive evidence for both fibre and fruit intake in protection against larger increases in WC. Also suggestive evidence was found for high intake of refined grains, and sweets and desserts in predicting more weight gain, and for refined (white bread and high energy density in predicting larger increases in WC. The results suggested that the proportion of macronutrients in the diet was not important in predicting changes in weight or WC. In contrast, plenty of fibre-rich foods and dairy products, and less refined grains, meat and sugar-rich foods and drinks were associated with less weight gain in prospective cohort studies. The results on the role of dietary macronutrient composition in prevention of weight regain (after prior weight loss were inconclusive.

    Nutrient deficiencies during childhood have adverse effects on child growth and health. In a single-arm 48-week long-term intervention, we previously reported the efficacy of oral nutritional supplementation (ONS) and dietary counselling on catch-up growth and growth maintenance in nutritionally at-risk Filipino children. The present analysis was done to assess the contributing effects of ONS to nutritional adequacy, dietary diversity, food intake and longitudinal growth. ONS (450 ml) was consumed daily providing 450 kcal (1880 kJ) and at least 50 % of micronutrient requirements among 200 children aged 3-4 years with weight-for-height percentiles between 5th and 25th (WHO Growth Standards). Weight, height and dietary intakes using 24-h food recalls were measured at baseline, and at weeks 4, 8, 16, 24, 32, 40 and 48. Nutrient adequacy and dietary diversity score (DDS) were calculated. Generalised estimating equations were used to assess the effects of total nutrient intakes, DDS, ONS compliance and sociodemographic factors on longitudinal growth. The percentages of children with adequate intake of energy, protein, Fe, Ca and some vitamins at each post-baseline visit were improved from baseline, reaching 100 % for most nutrients. DDS was also increased from baseline and reached significance from week 16 onwards (P Male children, total energy intake and parental employment status were associated with weight-for-height percentile gain (P nutritional adequacy and growth of Filipino children.

    Full Text Available Introduction. Shift-work determinates irregular nutrition habits. The quality as well as the quantity of meals consumed by shift-workers can significantly affects their health. Objective. The aim of this study was to evaluate the dietary habits of people performing shift work in the Bogdanka mine. Material and Methods. The study was carried out in the Bogdanka mine in Leczna. The questionnaire, which was designed by the author of this dissertation, was conducted among 700 shift-workers, working underground. The results were subjected to statistical analysis based on STATISTICA v. 7.1 (StatSoft, Poland software. Results. Nearly half of respondents reported regular consumption of meals (40.0% Interviewees admitted having warm meals during the day (81.4%. The most frequently consumed meal during the day was the hot one (50.9%, three meals and more were consumed the least frequently (8.1%. Almost half of respondents considered their eating habits as inappropriate (46.3%. Among those, nearly half (68.2% stated that shift – work is the reason for their nutrition habits. More than half of respondents (66.0% admitted that shift work hampers regular consumption of meals. Conclusions. Shift work makes nourishment and regular consumption difficult. It contributes to the limited amount of warm meals eaten during the day. In order to maintain preventive health care and the improvement of quality of life, shift workers should be provided with an easier access to meals (including warm one at specified times of the day.

    The aim of the study was to explore the expectations and experience of actually eating a healthy diet and using this experience to identify barriers to healthy eating and sustainable dietary change. Fifty participants (19-63 yrs) were provided with a healthy diet (i.e. complied with dietary recommendations) for three consecutive days. Afterwards a semi-structured interview was carried out to explore expectations, experience and barriers to healthy eating. Using a thematic analysis approach eight dominant themes emerged from the interviews. Four related to expectations and experience of healthy eating; realisation of what are appropriate portion sizes, an expectation to feel hungry, surprise that healthy diets comprised normal food, the desire for sweet snacks (e.g. chocolate). This demonstrated there are some misconception about healthy eating and distorted views of portion size. Four more themes emerged relating to barriers to healthy eating; competing priorities, social, peer and time pressure, importance of value for money, a lack of desire to cook. Poor knowledge of healthy eating or a lack of cooking skills were the least common barrier, suggesting that future interventions and policy to improve dietary intakes need to focus on social, cultural and economic issues rather than on lack of knowledge or skills.

    The presence of histones acts as a barrier to protein access; thus chromatin remodeling must occur for essential processes such as transcription and replication. In conjunction with histone modifications, DNA methylation plays critical roles in gene silencing through chromatin remodeling. Chromatin remodeling is also interconnected with the DNA damage response, maintenance of stem cell properties, and cell differentiation programs. Chromatin modifications have increasingly been shown to produce long-lasting alterations in chromatin structure and transcription. Recent studies have shown environmental exposures in utero have the potential to alter normal developmental signaling networks, physiologic responses, and disease susceptibility later in life during a process known as developmental reprogramming. In this review we discuss the long-term impact of exposure to environmental compounds, the chromatin modifications that they induce, and the differentiation and developmental programs of multiple stem and progenitor cell types altered by exposure. The main focus is to highlight agents present in the human lifestyle that have the potential to promote epigenetic changes that impact developmental programs of specific cell types, may promote tumorigenesis through altering epigenetic marks, and may be transgenerational, for example, those able to be transmitted through multiple cell divisions.

    A short-term exposure to resveratrol at high dosages exerts a remarkable cardioprotective effect. Whether a long-term exposure to resveratrol at low dosages that can be obtained through consumption of a resveratrol-rich diet is beneficial to heart diseases is unknown. We tested the effects of a resveratrol-enriched diet on cardiovascular remodeling of chronic heart failure (CHF) in rats resulting from permanent ligation of left coronary artery. Two weeks after surgery, rats were started on either a resveratrol-enriched (R; 5 mg/kg per day; n = 23) or normal (Control; n = 23) diet for next 10 months. Serial echocardiography in Control showed a significant decline in LV ejection fraction, increases in LV end-systolic and end-diastolic volumes, and expansion in myocardial infarct from pre-treatment values. In R, compared with Control, there were substantial improvements in those parameters. End-point LV pressure-volume loop analysis showed a significantly improved LV systolic function and AV-coupling, an index of energy transfer efficacy between the heart and aortic tree, in R compared with Control (p resveratrol supplement reduces cardiovascular structural and functional deterioration in CHF.

    While lifestyle modifications are currently used as firstline treatment for subjects with gastroesophageal reflux disease (GERD), the pathogenetic role of lifestyle factors and consequently, the efficacy of lifestyle measures is controversial. Our aim was to systematically review the pathogenetic link between overweight/ obesity, dietary habits, physical activity and GERD, and the beneficial effect of specific recommended changes, by means of the available literature from the 1999 to the present. Obesity, in particular, abdominal obesity, plays a key role in determining GERD symptoms and complications through mechanical and metabolic effects. Controlled weight loss (by diet or surgery) is effective in improving GERD symptoms. No definitive data exist regarding the role of diet and, in particular, of specific foods or drinks, in influencing GERD clinical manifestations. Moderate physical activity seems to be beneficial for GERD, while vigorous activity may be dangerous in predisposed individuals. In conclusion, being obese/overweight and GERD-specific symptoms and endoscopic features are related, and weight loss significantly improves GERD clinical-endoscopic manifestations. The role of dietary behavior, mainly in terms of specific dietary components, remains controversial. Mild routine physical activity in association with diet modifications, i.e. a diet rich in fiber and low in fat, is advisable in preventing reflux symptoms.

    As the understanding of the nutritional regulation of muscle growth mechanisms in fish is fragmentary, the present study aimed to (1) characterise ontogenetic changes in muscle growth-related genes in parallel to changes in muscle cellularity; (2) determine whether an early decrease in dietary protein:energy ratio by fat addition affects the muscle growth mechanisms of rainbow trout (Oncorhynchus mykiss) alevins; and (3) determine whether this early feeding of a high-fat (HF) diet to alevins had a long-term effect on muscle growth processes in juveniles fed a commercial diet. Developmental regulation of hyperplasia and hypertrophy was evidenced at the molecular (expression of myogenic regulatory factors, proliferating cell nuclear antigen and myosin heavy chains (MHC)) and cellular (number and diameter of white muscle fibres) levels. An early decrease in dietary protein:energy ratio by fat addition stimulated the body growth of alevins but led to a fatty phenotype, with accumulation of lipids in the anterior part, and less caudal muscle when compared at similar body weights, due to a decrease in both the white muscle hyperplasia and maximum hypertrophy of white muscle fibres. These HF diet-induced cellular changes were preceded by a very rapid down-regulation of the expression of fast-MHC. The present study also demonstrated that early dietary composition had a long-term effect on the subsequent muscle growth processes of juveniles fed a commercial diet for 3 months. When compared at similar body weights, initially HF diet-fed juveniles indeed had a lower mean diameter of white muscle fibres, a smaller number of large white muscle fibres, and lower expression levels of MyoD1 and myogenin. These findings demonstrated the strong effect of early feed composition on the muscle growth mechanisms of trout alevins and juveniles.

    The Family Influences on Food Intake study (FIFI), is a longitudinal study on dietary habits of young children and the primary socialization of these habits during childhood and during the transition into adolescence. Special attention is paid to the development, validation and feasibility of instruments measuring as well dependent as independent variables useful for large scale surveys. Parents of preschool children from the first year (+/-3 years of age) of 56 school departments were asked to complete a self-administered questionnaire biennially. Data of 862 children was available for the first measurement (2008). A web based dietary record tool was developed to investigate the relative validity of the Food Frequency Questionnaire (FFQ) used in the study. Two hundred and seventeen parents completed the online tool for three non-consecutive days. The feasibility of the online data collection is investigated and the reported intake is compared with the FFQ estimates. Associations between nutritional knowledge and attitudes of the children's mothers and dietary patterns of the children (FFQ) are investigated as well as relations between parent and child characteristics and fruit and vegetable intake. Additionally, 70 teachers completed a questionnaire on their attitudes towards the school food policy. The teachers' responses are compared with responses of parents from a previous study. Finally, the feasibility of an animated web based fruit and vegetables preferences tool, to be used in the follow up surveys, has been investigated in 4-6 years old (n=139 for fruit and n=135 for vegetables). The findings are summarized in the present paper.

    Several studies suggest that dietary habits are associated with poor academic performance. However, few studies have evaluated these relations after adjusting for numerous confounding factors. This study evaluated the frequency of various diet items (fruit, soft drinks, fast foods, instant noodles, confections, vegetables, and milk) and the regularity of meal times (breakfast, lunch, and dinner) all at once.A total of 359,264 participants aged from 12 to 18 years old were pooled from the Korea Youth Risk Behavior Web-based Survey (KYRBWS) for the 2009 to 2013 period. Dietary habits over the last 7 days were surveyed, including the regularity of consuming breakfast, lunch and dinner and the frequency of eating fruits, soft drinks, fast foods, instant noodles, confections, vegetables, and milk. Physical activity, obesity, region of residence, subjective assessment of health, stress level, economic level, and parental education level were collected from all of the study participants. School performance was classified into 5 levels. The adjusted odds ratios (AORs) of dietary habits for school performance were analyzed using multinomial logistic regression analyses with complex sampling. Structural equation modeling was used to analyze the effects of diet factors on school performance while considering the effects of other variables on both diet factors and school performance.Frequent intakes of breakfast (AOR = 2.34, 95% confidence interval [CI] = 2.20-2.48), fruits (AOR = 1.73, 95% CI = 1.62-1.86), vegetables (AOR = 1.48, 95% CI = 1.37-1.61), and milk (AOR = 1.35, 95% CI = 1.28-1.43) were related to high levels of school performance (each with P instant noodles (AOR = 0.62, 95% CI = 0.55-0.70), fast food (AOR = 0.83, 95% CI = 0.72-0.96), and confectionary (AOR = 0.86, 95% CI = 0.80-0.93) were negatively associated with school performance (each with P instant noodles, fast foods, and confections.

    Methoxychlor is an insecticide with estrogen-like activity, thus exposure during development might cause sexually dimorphic behavioral alterations. To evaluate this, pregnant rats consumed diets containing 0, 10, 100 or 1000 ppm methoxychlor from gestational day 7, and offspring continued on these diets until postnatal day (PND) 77. Assessments of sexually dimorphic behaviors in offspring indicated that intake of a 3.0% sodium chloride solution was significantly increased (41%) in males and females of the 1000 ppm group. No treatment group differed from controls in open field nor running wheel activity, play behavior, nor 0.3% saccharin solution intake. Offspring of the 1000 ppm group showed significantly decreased body weight, reaching 17% less than controls at PND 77, but not clearly related to their salt solution intake. During pregnancy, 1000 ppm dams consumed 23% less food and weighed 10% less than controls, but this did not affect litter outcomes. These results indicate that in rodents, developmental and chronic exposure to dietary methoxychlor alters the sexually dimorphic behavior of salt-solution intake in young adults of both sexes. Similar behavioral alterations with other xenoestrogens, and the potential for interactions among xenoestrogens, suggest that this report may minimize the true effects of dietary methoxychlor exposure.

    Cognitive impairment is common in heart failure patients. Poor dietary habits are associated with reduced neurocognitive function in other medical populations, including diabetes and Alzheimer's disease. This study examined whether dietary habits help moderate the relationship between heart failure severity and cognitive function. A total of 152 persons with heart failure completed neuropsychological testing and a fitness assessment. Dietary habits were assessed using the Starting the Conversation-Diet questionnaire, a nutrition measure suggested for use in primary care settings. Moderation analyses showed that better dietary habits attenuated the adverse impact of heart failure severity on frontal functioning (b = 1.28, p dietary habits can moderate the association between heart failure and performance on tests of attention and executive function. Longitudinal studies are needed to confirm and clarify the mechanisms for our findings.

    Objective This study examined whether changes in self-efficacy explain the effects of a mailed print intervention on long-term dietary practices of breast and prostate cancer survivors. The relationship between change in self-efficacy and long-term physical activity (PA) also was examined. Methods Breast and prostate cancer survivors (N=543) from 39 U.S. states and two Canadian provinces participated in the FRESH START intervention trial. Participants were randomly assigned to receive a 10-month program of mailed print materials on diet and PA available in the public domain or a 10-month program of tailored materials designed to increase fruit and vegetable (F&V) intake, decrease fat intake, and/or increase PA. Changes in self-efficacy for F&V intake and fat restriction were analyzed as potential mediators of the intervention’s effects on diet at 2-year follow-up. Because we previously found that change in self-efficacy for PA did not vary by group assignment, the relationship between change in self-efficacy and PA at 2-year follow-up was examined across study conditions. Results Results suggest that change in self-efficacy for fat restriction partially explained the intervention’s effect on fat intake (mean indirect effect=-.28), and change in self-efficacy for F&V consumption partially explained the intervention’s effect on daily F&V intake (mean indirect effect=.11). Change in self-efficacy for fat restriction partially accounted for the intervention’s impact on overall diet quality among men only (mean indirect effect=.60). Finally, change in self-efficacy for PA predicted PA at 2-year follow-up. Conclusions Findings suggest that self-efficacy may influence long-term maintenance of healthy lifestyle practices among cancer survivors. PMID:22544562

The study included 150 patients (75 patients suffering from recurrent depressive disorders. and 75 healthy people aged 18-64 years. The assessment of dietary habits was carried out by using a food frequency questionnaire. Results. It has been shown that in the compared groups of women, patients with depression consumed significantly less groats (p<0.001, rice (p= 0.02, red meat (p<0.01, fish (p<0.01, vegetables (p<0.001, fruits (p<0.01 and wine (p<0.001 in comparison with women without depression, and they were significantly more likely to consume wheat-rye bread (p= 0.03, cheese (p=0.02, butter (p=0.03, cream (p<0.01, lard (p <0.001, coffee (p=0.03 and sugar (p=0.02 in comparison with women without depression. Statistically significant differences between the two groups of men were diagnosed in the frequent intake of lard (p<0.001 and less frequent vegetable oils (p<0.01, beer (p= 0.01, and fast food (p<0.01 for men with depression compared with men in the control group. Conclusions. In the treatment of patients with depression during the declared change of diet, the need for nutrition education on the principles of rational nutrition should be taken into attention, including the selection of appropriate food groups in order to ensure an optimal supply of all necessary to the proper functioning of the body’s nutrients.

    We analyzed long-term sustainability of improved blood Phenylalanine (Phe) control and changes to dietary Phe tolerance in 11 patients (1 month to 16 years), with various forms of primary PAH deficiency (classic, moderate, severe phenylketonuria [PKU], mild hyperphenylalaninemia [HPA]), who were treated with 15-20mg/kg/d Sapropterin-dihydrochloride during a period of 13-44 months. 7/11 patients had a sustainable, significant reduction of baseline blood Phe concentrations and 6 of them also had an increase in mg/kg/day Phe tolerance. In 2 patients with mild HPA, blood Phe concentrations remained in the physiologic range even after a 22 and 36% increase in mg/kg/day Phe tolerance and an achieved Phe intake at 105% and 268% of the dietary reference intake (DRI) for protein. 2 of these responders had classic PKU. 1 patient with mild HPA who started treatment at 2 months of life, had a significant and sustainable reduction in pretreatment blood Phe concentrations, but no increase in the mg/kg/day Phe tolerance. An increase in Phe tolerance could only be demonstrated when expressing the patient's daily Phe tolerance with the DRI for protein showing an increase from 58% at baseline to 78% of normal DRI at the end of the observation. Long-term follow-up of patients with an initial response to treatment with Sapropterin is essential to determine clinically meaningful outcomes. Phenylalanine tolerance should be expressed in mg/kg/day and/or % of normal DRI to differentiate medical therapy related from physiologic growth related increase in daily Phe intake.

    Wildcaught cinnamon ringtail monkeys, Cebus albifrons, were fed diets with Ca:P ratios of 1:4 1:2.1 1:0,4, and 1:0.5 for 3 to 88 months. Monkeys fed the diet with Ca:P ratios of 1:4 and 1:21 C ratios similar to that of human diets) had minor microscopic changes suggestive of osteoporosis when compared to other species of animals. The changes were not detected by conventional or magnification radiography or by 125I photon absorptiometry. These findings are in in striking contrast to studies in other animals where similar diets resulted in significant bone resorption within 6 weeks to 6 months. This study suggests that the non-human primate may be a more appropriate animal model for the investigation of nutritional osteopenia in man in whom bone resorption appears to be a slowly progressive process. In view of our findings, studies using lower animal species must be re-evaluated with respect to the hypothesis that high dietary phosphate is a significant etiologic factor in senile osteoporosis in man.

    Full Text Available Alzheimer's disease (AD is a devastating age-related neurodegenerative disease with no specific treatment at present. The APPsw/Tg2576 mice exhibit age-related deterioration in memory and learning as well as amyloid-beta (Aβ accumulation, and this mouse strain is considered an effective model for studying the mechanism of accelerated brain aging and senescence. The present study was aimed to investigate the beneficial effects of dietary supplements pomegranate, figs, or the dates on suppressing inflammatory cytokines in APPsw/Tg2576 mice. Changes in the plasma cytokines and Aβ, ATP, and inflammatory cytokines were investigated in the brain of transgenic mice. Significantly enhanced levels of inflammatory cytokines IL-1β, IL-2, IL-3, IL-4, IL-5, IL-6, IL-9, IL-10, TNF-α and Eotaxin activity were decreased by administration of the diet supplements containing pomegranates, figs, or dates. In addition, putative delays in the formation of senile plaques, as indicated by a decreasing tendency of brain Aβ1-40 and Aβ1-42 contents, were observed. Thus, novel results mediated by reducing inflammatory cytokines during aging may represent one mechanism by which these supplements exert their beneficial effects against neurodegenerative diseases such as AD.

    Full Text Available One thousand two hundred 1-day-old Lohmann LSL white and Lohmann Brown layer chickens were fed diets supplemented with either an antibiotic growth promoter (AGP or an herbal essential oil mixture (EOM till 58 wk of age to reveal the long-term effects of those additives on growth, performance and wholesome egg quality parameters. The study was arranged in a 2x3 factorial design with two layer strains and three feed additive regimens. Thus, the layer birds of both strains were randomly assigned to the three dietary treatments, i.e., standard basal diet (control, control with AGP (specifically, avilamycin, 10 mg/kg diet and control with EOM (24 mg/kg diet. The data regarding egg production were recorded between 22 to 58 weeks of age. Neither the dietary treatments nor the bird strain influenced the body weight and mortality of the birds in both the growing and laying period. AGP or EOM supplementation to the laying hen diet significantly increased the egg production rate and egg weight as compared to the control  diet alone, but egg mass output, feed consumption, and feed conversion ratio were not effected  by the dietary treatments. Neither dietary treatment created any statistically significantly differences in egg quality parameters with the exception of Haugh unit. The research findings have confirmed the beneficial effects of supplementation with feed-grade EOM on the laying rate and egg weight of both white and brown layers. Indeed, EOM, being a novel feed additive natural origin, proved to be as efficacious as AGP in promoting egg yield.

The study was developed in a sample of 159 patients, who were given a self-reported questionnaire, to ascertain the influence of socio-familiar aspects, pharmacological treatment, and dietary habits. Anthropometric measurements (body mass index (BMI) and waist circumference (WC)) were also taken. Patients with schizophrenia presented unhealthy dietary habits, as indicated by the finding that 51% of the patients took no longer than 15 min to eat, 40.8% did not eat fruit daily, and 63.1% did not eat fish. Women were three times more likely to be obese than men (odds ratio (OR) = 2.91, P = 0.021). Patients classified as having unhealthy dietary habits have a 2.33-fold higher risk of obesity than patients with good dietary habits (OR = 2.33, P = 0.034). In summary, this paper highlights the fact that patients with schizophrenia have a detrimental dietary pattern that is associated with an increase in BMI and WC, with the consequent development of obesity and related metabolic alterations, regardless of the pharmacological treatment being followed. Future research directions will include exploring the need for nutritional education programmes to improve the dietary habits of such patients.

    OBJECTIVE To study the relation among methylenetetrahydrofolate reductase (MTHFR) C677T genotypes, dietary habits and the risk of stomach cancer (SC).METHODS A case-control study was conducted with 107 cases of SC and 200 population-based controls in Chuzhou district, Huaian, Jiangsu province, China. The epidemiological data were collected, and DNA of peripheral blood leukocytes was obtained from all of the subjects..MTHFR genotypes were detected by PCR-RFLP. RESULTS (1) The prevalence of the MTHFR C/T or T/T genotypes was found to be significantly different between controls (68.5%) and SC cases (79.4%,P=0.0416), the increased risk had an adjusted OR of 1.79 (95%C1:1.01-3.19). (2) Among subjects who had a low intake of garlic or Chinese onion, MTHFR C/T or T/T genotypes significantly increased the risk of developing SC. Among non-tea drinkers or among subjects who had a frequent intakeof meat, the carriers of the MTHFR C/T or T/T genotypes had a higher risk of SC than individuals with the C/C type MTHFR. CONCLUSION The polymorphism of MTHFR C677T was associated with increased risk of developing SC, and that individuals with differing genotypes may have different susceptibilities to SC, based on their exposure level to environmental factors.

    Converging evidence suggests that an imbalance of ω3 to ω6 polyunsaturated fatty acid (PUFA) in the brain is involved in mental illnesses such as anxiety disorders. However, the underlying mechanism is unknown. We previously reported that the dietary ratio of ω3 to ω6 PUFA alters this ratio in the brain, and influences contextual fear memory. In addition to behavioral change, enhancement of cannabinoid CB1 receptor-mediated short-term synaptic plasticity and facilitation of the agonist sensitivity of CB1 receptors have been observed in excitatory synaptic responses in the basolateral nucleus of the amygdala (BLA). However, it is not known whether long-term synaptic plasticity in the amygdala is influenced by the dietary ratio of ω3 to ω6 PUFA. In the present study, we examined long-term potentiation (LTP) of optogenetically-evoked excitatory synaptic responses in synapses between the terminal of the projection from the auditory cortex (ACx) and the pyramidal cells in the lateral nucleus of the amygdala. We found that LTP in this pathway was attenuated in mice fed with a high ω3 to ω6 PUFA ratio diet (0.97), compared with mice fed with a low ω3 to ω6 PUFA ratio diet (0.14). Furthermore, mice in the former condition showed reduced fear responses in an auditory fear conditioning test, compared with mice in the latter condition. In both electrophysiological and behavioral experiments, the effect of a diet with a high ω3 to ω6 PUFA diet ratio was completely blocked by treatment with a CB1 receptor antagonist. Furthermore, a significant reduction was observed in cholesterol content, but not in the level of an endogenous CB1 receptor agonist, 2-arachidonoylglycerol (2-AG), in brain samples containing the amygdala. These results suggest that the balance of ω3 to ω6 PUFA has an impact on fear memory and cortico-amygdala synaptic plasticity, both in a CB1 receptor–dependent manner. PMID:27601985

    This study investigated (a) changes in ghrelin and peptide YY (PYY) concentrations during a weight reduction programme and (b) baseline ghrelin and PYY levels as predictors of weight loss in 32 severely obese adolescents (BMI z score = 4.1). Subjects spent an academic year in an institution for childhood obesity. Fasting ghrelin and PYY, leptin, insulin levels and insulin resistance were measured at baseline (month 0) and during the programme (months 3, 6, 9). In addition, 15 normal-weight teenagers served as reference for the baseline assessments. At baseline, obese teenagers had lower ghrelin and PYY concentrations than normal-weight adolescents (P teenagers, associated with an increase in ghrelin (apparent from month 6; P adolescents with severe obesity, a long-term combination of supervised aerobic exercises and a balanced diet led to weight reduction and increased ghrelin concentrations, without any change in PYY concentrations. Moreover, baseline PYY concentrations might be considered as predictors of weight loss.

    Research has suggested that the consumption of foods rich in polyphenols is beneficial to the cognitive functions of the elderly. We investigated the effects of grape consumption on spatial learning, memory performance and neurodegeneration-related protein expression in aged rats fed a high-fructose-high-fat (HFHF) diet. Six-week-old Wistar rats were fed an HFHF diet to 66 weeks of age to establish a model of an HFHF dietary pattern, before receiving intervention diets containing different amounts of grape powder for another 12 weeks in the second part of the experiment. Spatial learning, memory performance and cortical and hippocampal protein expression levels were assessed. After consuming the HFHF diet for a year, results showed that the rats fed a high grape powder-containing diet had significantly better spatial learning and memory performance, lower expression of β-amyloid and β-secretase and higher expression of α-secretase than the rats fed a low grape powder-containing diet. Therefore, long-term consumption of an HFHF diet caused a decline in cognitive functions and increased the risk factors for neurodegeneration, which could subsequently be ameliorated by the consumption of a polyphenol-rich diet.

    The scope of this study was to conduct a systematic review to establish the major dietary habits of adolescents and the corresponding association with cardiovascular risk factors. Research was performed in the LILACS, SciELO, PubMed, Scopus and Web of Science databases in addition to a manual search for original articles published between 2005 and 2014. Of the 371 entries identified; 26 fulfilled the inclusion criteria and were covered in the review. The main dietary habits observed were Western (61%) Healthy (42%) and Traditional (38%). Western dietary habits were positively associated with total cholesterol and SM, while Healthy dietary habits were inversely associated with fasting glycaemia, DBP and SM and positively with HDL-C, all of the aforementioned associations with very low (D) quality of evidence in accordance with the GRADE rating. The Traditional dietary habits were considered a risk factor for hyperglycemia, hyperinsulinemia and hypertriglyceridemia and protection for physical activity and eutrophic BMI. Although these results need to be analyzed with caution, due to the low quality of evidence, there is a clear need for actions aimed at promoting healthy dietary habits in adolescents in order to contribute to the prevention of cardiovascular risk factors.

  1. Exploring the Missing Links between Dietary Habits and Diseases.

    Disease dietomics is an emerging area of systems biology that attempts to explore the connections between the dietary habits and diseases. Some of the topical studies highlight that foods might have different impacts over an organism either in progressing a disease (negative association) or in fighting against it (positive association). The association of foods with different diseases can be put together to build a network that might provide a global view of the entire system. Again, such disease-food networks might emerge in a more complex form while considering the disease subtypes individually. Some foods might have positive association with a particular subtype of a disease, whereas it might have no association or negative association with another subtype of the same disease. Therefore, the subtypes might have completely different network patterns. On the other hand, the same food may be helpful for a disease and harmful for another disease or even for a subtype. Analyzing such disease-food networks in different forms might give us important information about the relations between different diseases. In this study, we have analyzed a large-scale disease-food network comprising 162 different diseases and 455 types of foods for gaining knowledge about the connection between these diseases and their subtypes. We have measured the similarity between diseases based on their patterns of association with foods. In addition to observing a high similarity between several disease sub types, particularly for cancer, we have found strong relations between constipation-dysphagia and cancer-cardiovascular disease, which are rarely known. Tendency of occurrence of different diseases can be predicted based on such information.

    This research evaluated the psychometric properties of English version of dietary habits questionnaires developed for type 2 diabetic patients. There is scarcity of literature about availability of standardized questionnaires for assessing dietary habits of type 2 diabetics in Saudi Arabia. As dietary habits vary from country to country, therefore, this was an attempt to develop questionnaires that can serve as a baseline. Through intensive literature review, four questionnaires were developed / modified and subsequently tested for psychometric properties. Prior to pilot study, a pre-test was conducted to evaluate the face validity and content validity. The pilot study was conducted from 23 October – 22 November, 2016 to evaluate the questionnaires’ reliability and validity. Systematic random sampling technique was used to collect the data from 132 patients by direct investigation method. Questionnaires assessing diabetes mellitus knowledge (0.891), dietary knowledge (0.869), dietary attitude (0.841) and dietary practices (0.874) had good internal consistency reliability. Factor analysis conducted on dietary attitude questionnaire showed a valid 5 factor solution. Directions of loadings were positive and free from factorial complexity. Relying on the data obtained from type 2 diabetics, these questionnaires can be considered as reliable and valid for the assessment of dietary habits in Saudi Arabia and neighbouring Gulf countries population.

    A systematic review of the literature suggests the dietary habits of some ethnic groups living in Europe are likely to become less healthy as individuals increase consumption of processed foods that are energy dense and contain high levels of fat, sugar, and salt. Such products often replace healthy dietary components of the native diet, such as fruits, vegetables, nuts, and grains. Mixed food habits are emerging mainly amongst younger people in the second and third generations, most likely due to acculturation and adoption of a Western lifestyle. Age and immigrant generation are the major factors accounting for changes in dietary habits, whilst income, level of education, dietary laws, religion, and food beliefs are also important factors. Obesity, cardiovascular disease, diabetes, and hypertension present major problems for the mainstream European population. However, the risk of chronic disease is reported to be higher in ethnic populations, particularly South Asians, African Caribbeans, and Mexicans.

    The purpose of this study was to assess weight status, dietary habits, physical activity, dietary beliefs, and nutrition knowledge among a sample of students from Central Michigan University. A cross-sectional survey was conducted among a sample of undergraduate students in Fall 2011 and Spring 2012 at Central Michigan University. Participating students completed an online questionnaire that included questions related to their eating habits, physical activity and lifestyle, dietary beliefs, and nutritional knowledge. Weight, height, and waist circumference were measured. Percentage body fat and visceral fat score were determined using a Tanita body composition analyser (SC-331S). Outcomes of this study indicated that 78% of female students were within the healthy weight range compared to 52% of male students. Visceral body fat and waist circumference scores were higher in males than in females. Most students showed 'satisfactory' dietary habits. Almost half of the students reported drinking two glasses of milk and consuming two cups of fruits and vegetables daily. Physical activity and lifestyle score indicated that most of the students were not physically active. Only 7% of students reported having a very active lifestyle, and 4% had quite good nutritional knowledge. The majority of students, particularly females, were within the healthy body weight range. Students' dietary habits were satisfactory. However, physical activity, students' knowledge of healthy and unhealthy diet habits, and nutritional knowledge needed improvement. Developing gender-specific programmes for promoting healthy lifestyle behaviours among students is recommended. © Royal Society for Public Health 2015.

    The influence of long-term exposure of goldfish to dietary cadmium (Cd) on its accumulation in tissues, growth, ovarian development, luteinizing hormone (LH) secretion and a response to hormonal stimulation of spawning were evaluated. The study was conducted on four groups of females for the period of 3 years, from the age of 10 weeks to second spawning. Four doses of Cd were applied in the feed: 0 (control group), 0.1, 1 and 10 mg Cd g{sup -1} of feed (wet weight). The highest dose of Cd (10 mg g{sup -1}) inhibited growth and caused several behavioural effects. In contrast, lower dose of Cd (1 mg g{sup -1}) stimulated fish growth. The doses of Cd from 0.1 to 1 mg Cd g{sup -1} did not influence ovarian development. The gonado-somatic index (GSI) and histological analysis of ovaries showed no differences in ovarian development between the control group and the groups receiving these doses of Cd. However, in the group receiving the highest Cd dose, GSI decreased. This was associated with persistent, long-lasting elevation of plasma LH levels. Ovulation did not occur in this group. Injections of salmon GnRH-analogue (sGnRHa) alone or with domperidone (a dopamine receptor antagonist) in sexually mature fish caused an increase of LH levels in all groups, although in the group fed with the highest Cd dose the effect was weaker than in the other groups. After the first spawning season, a negative effect of lower Cd doses (0.1 and 1 mg Cd g{sup -1}) on ovarian recrudescence (rebuilding of ovaries) and on the response to the consecutive hormonal stimulation of spawning was observed (lower number of ovulating females). There was a significantly higher content of Cd in the livers of fish than in their muscles. The results of hormonal stimulation of spawning and histological analysis of ovaries suggest that in goldfish cadmium acts mainly at the level of ovary rather than on the pituitary gland. We suppose that in the natural environment cadmium present in the feed can play an

    Full Text Available Abstract Background The fastest growing age group globally is older adults, and preventing the need for long-term nursing care in this group is important for social and financial reasons. A population approach to diet and physical activity through the use of social services can play an important role in prevention. This study examined the effectiveness of a social health program for community-dwelling older adults aimed at introducing and promoting physical activity in the home at each individual’s pace, helping participants maintain good dietary habits by keeping self-check sheets, and determining whether long-standing unhealthy or less-than-ideal physical and dietary habits can be changed. Method This cluster randomized trial conducted at 6 community centers in an urban community involved 92 community-dwelling older adults aged 65–90 years. The intervention group (3 community centers; n = 57 participated in the social health program “Sumida TAKE10!” which is an educational program incorporating the “TAKE10!® for Older Adults” program, once every 2 weeks for 3 months. The control group (3 community centers; n=35 was subsequently provided with the same program as a crossover intervention group. The main outcome measures were changes in food intake frequency, food frequency score (FFS, dietary variety score (DVS, and frequency of walking and exercise. The secondary outcome measures were changes in self-rated health, appetite, and the Tokyo Metropolitan Institute of Gerontology (TMIG Index of Competence score. Results Compared to baseline, post-intervention food intake frequency for 6 of 10 food groups (meat, fish/shellfish, eggs, potatoes, fruits, and seaweed, FFS, and DVS were significantly increased in the intervention group, and interaction effects of FFS and DVS were seen between the two groups.

    Adoption of optimal dietary habits during adolescence is associated with better health outcomes later in life. However, the associations between a pattern of healthy dietary habits encapsulated in an index and sociodemographic and nutrient intake have not been examined among adolescents. This study aimed to develop a behavior-based diet index and examine its validity in relation to sociodemographic factors, nutrient intakes, and biomarkers in a representative sample of New Zealand (NZ) adolescents aged 15-18 y (n = 694). A 17-item Healthy Dietary Habits Score for Adolescents (HDHS-A) was developed based on dietary habits information from the 2008/2009 NZ Adult Nutrition Survey. Post hoc trend analyses were used to identify the associations between HDHS-A score and nutrient intakes estimated by single 24-h diet recalls and selected nutritional biomarkers. Being female, not of Maori or Pacific ethnicity, and living in the least-deprived socioeconomic quintile were associated with a higher HDHS-A score (all P adolescents.

    Obesity has become a major health concern due to the increased risk of co-morbidities, resulting in decreased quality of life, stigmatization, reduced working ability and early death. This causes a great challenge for the health care systems and results in increased direct costs related to treatment of obesity and co-morbidities, as well as increased indirect costs related to reduced function and withdrawal from the labour market. Both between and within societies, large variation in the prevalence of overweight and obesity exists. This variation is caused by differences in environmental exposures as well as genetic differences between individuals, resulting in differentiated susceptibility to environmental exposures. The evidence for genetic influence on anthropometry has previously been established and has been estimated to be 60-70% based on twin studies. These inter-individual differences can, however, not explain the increase in obesity prevalence during the past 70 years. Environmental factors must therefore play an important role in the obesity epidemic. Habitual diet is one of many environmental factors that potentially contribute to the inter-individual differences in body fat mass, but only limited evidence for associations between habitual dietary intake and anthropometry exists. Differences in habitual dietary intake are also partly determined by differences in genes influencing smell and taste preferences. But, so far, only few studies have investigated genetic influences on dietary intake in adults and the interplay between diet, genes and obesity. The focus of the thesis was to investigate the genetic and environmental influence on habitual diet and obesity as well as the association between habitual diet and anthropometry. The thesis is based on structural equation modelling of twin data from the Danish Twin Registry with special focus on the GEMINAKAR twin study that was performed in 1997-2000. In this study, anthropometric traits of the twin pairs

    Background Dietary habits and depression are each associated with cardiovascular disease risk. Patient with depression often report poor eating habits and dietary factors may help explain commonly observed associations between depression and cardiovascular disease. Method From 1996–2000, 936 women were enrolled in the Women's Ischemia Syndrome Evaluation (WISE) at four US academic medical centers at the time of clinically indicated coronary angiography and then assessed (median follow-up, 5.9 years) for adverse outcomes (cardiovascular disease death, heart failure, myocardial infarction, stroke). Participants completed a protocol including coronary angiography (coronary artery disease severity), depression assessments (Beck Depression Inventory [BDI] scores, antidepressant use, & depression treatment history). A subset of 201 women (mean age= 58.5(SD=11.4) further completed the Food Frequency Questionnaire for Adults (FFQ; 1998 Block). We extracted daily fiber intake and daily servings of fruit and vegetables as measures of dietary habits. Results In separate Cox regression models adjusted for age, smoking, and coronary artery disease severity, Beck Depression Inventory scores (HR=1.05, 95% CI=1.01–1.10), antidepressant use (HR=2.4, 95% CI=1.01–5.9) and a history of treatment for depression (HR=2.4, 95%CI=1.1–5.3) were each adversely associated with time to cardiovascular disease outcomes. Fiber intake (HR=.87, 95% CI=.78–.97) and fruit and vegetable consumption (HR=.36, 95% CI=.19–.70) was associated with a decreased time to cardiovascular disease event risk. In models including dietary habits and depression, fiber intake and fruit and vegetable consumption remained associated with time to cardiovascular disease outcomes, whereas depression relationships were reduced by 10–20% and non-significant. Conclusions Among women with suspected myocardial ischemia, we observed consistent relationships between depression, dietary habits, and time to

    The present study examined differences in dietary habits and physical activity levels between students attending private and public high schools in Jordan. A total of 386 secondary-school males and 349 females aged 14-18 years were randomly recruited using a multistage, stratified, cluster sampling technique. Dietary habits and physical activity level were self-reported in a validated questionnaire. The prevalence of obesity was significantly higher among adolescents in private (26.0%) than in public schools (16.7%). The frequency of breakfast intake was significantly higher among adolescents in private schools, whereas French fries and sweets intake was significantly higher in public schools. Television viewing showed a significant interaction with school type by sex. A higher rate of inactivity was found among students attending private schools. Despite a slightly better overall dietary profile for students in private schools, they had a higher rate of overweight and obesity compared with those in public schools.

    Full Text Available Background Overweight and obesity have increased rapidly in incidence to become a global issue today. Overweight and obesity problems are significantly linked to unhealthy dietary patterns, physical inactivity and misperception of body image. This study aimed to determine whether Malaysian children build healthy eating habits from childhood. Methods A survey on eating habits was conducted among primary school students in standards 4 to 6 in the state of Selangor, Malaysia. The findings of the study were reported in the form of descriptive statistics involving frequencies and percentages. Data from 400 respondents were analyzed. Results Our findings showed that the students understood the definition of healthy food and the types of food that are considered healthy. Although the students knew that food such as deep-fried drumsticks and hamburgers contain a high amount of saturated fat and cholesterol, these foods were still consumed by them. There was also a high consumption of foods that are fried and contain sugar, salt and saturated fat. In choosing food, two major factors contributed to the students’ decisions: cleanliness (65.8% and the preference of their parents (12.3%. Discussion Our findings indicate that by implementing the Integrated School Health Program (ISHP properly, students’ eating habits can be improved by creating a school with a healthy environment.

    Consumption of non-core foods in childhood is associated with excessive weight gain in childhood. Parents play a vital role in establishing healthy diet behaviours in young children. The aim of this study was to assess the effectiveness of a telephone-based intervention in reducing child consumption of non-core foods, and to examine parent and home food environment mediators of change in child consumption. The 'Healthy Habits' trial utilised a clustered randomised controlled design. Parents were recruited from 30 preschools (N=394 participants, mean age 35.2±5.6 years). Parents randomized to the intervention group received four telephone contacts and print materials. Parents allocated to the control condition receive generic print materials only. Non-core food consumption was assessed using a validated child dietary questionnaire at baseline, 2 and 6 months post recruitment in 2010. The intervention was effective in reducing child consumption of non-core foods at 2 months (intention to treat analysis: z=-2.83, ppreschool age children, however further development is needed to sustain the effect in the long-term.

    Full Text Available Diet appears to have some role in stroke development. The objective of our study was to describe the dietary habits in patients admitted with acute ischemic stroke and compare selected dietary components with healthy controls. Adherence to healthy diet behaviors was also assessed.A case-control study of consecutive patients with acute ischemic stroke admitted to the Neurology Department of Hospital del Mar from 2007 to 2010. Patients were matched by age and sex with control subjects. A previously validated nutritional survey was administered to patients and controls. Demographic data, vascular risk factors, caloric intake and dietary nutrients were evaluated. Intention to follow a healthy diet was also assessed in both groups.A total of 300 acute ischemic stroke patients and 300 controls with evaluation of dietary habits. No differences were observed in vascular risk factors, except smoking habit, diabetes and ischemic heart disease. Stroke patients reported a higher caloric intake: 2444.8(1736.8-3244.5 vs 2208.7(1753.1-2860.7 Kcal, p = 0.001.

    Full Text Available Abstract Background Nutrition has been widely recognized to influence the risk of kidney stone formation. Therefore the aim of our study was to assess: a whether usual diet of women with idiopathic calcium nephrolithiasis (ICN living in Parma (Northern-Italy is different compared to healthy controls, b how their diet differs from Italian National guidelines and c whether it is related to nephrolithiasis clinical course. Methods 143 women with recurrent ICN (mean age 43 ± 13 ys and 170 healthy women (mean age 42 ± 11 ys were enrolled. All women completed a food frequency questionnaire for the last 60-days and a 3-day dietary diary analysed with a dedicated software. Results Stone formers showed a higher consumption of sausages, ham, meat and sweets than healthy controls (43.1% vs 11.1%, 29.4% vs 13.9%, 21.6% vs 4.2%, 66.7% vs 18.1%, p 40 years, the differences described above were amplified in the class ≤30 years, where nephrolithiasis presented a more serious course (shorter recurrence interval, greater stone-rate. In this age group the intake of fruit and vegetables was notably lower than guideline recommendations. Conclusions We conclude that the usual diet of women with recurrent ICN is different from controls and characterized by low intake of fruits and vegetables and higher consumption of simple sugars and foods with high protein and salt content. This dietary imbalance could play a role in the ICN pathogenesis, especially in younger women. This work was financed by grants from Italian Ministry of University and Research as part of a larger project about the prevention of kidney stones (PRIN 2005063822 and by Fondazione per la Ricerca Scientifica Termale (FoRST.

    Full Text Available Both the amount and the quality of consumed food have a direct impact on health. There has been a noticeable increase in frequency of fast food consumption. The aim of the paper was to assess the food habits in a selected group of quick service restaurant employees, who have easy access to fast food. The survey was conducted at the end of 2014/beginning 2015 among 270 purposively selected McDonald’s Warsaw restaurant employees. An original survey questionnaire was employed. Statistica software was used to process the data; correlation coeffi cient was calculated taking p < 0.5 as the level of statistical signifi cance. The survey points to many nutritional errors committed by the employees, including too long intervals between meals and frequent fast food consumption. Additionally, it was observed that seniority played a role in food preferences: the longer the employee’s length of service, the more often would they consume McDonald’s-bought products. It was determined that place of employment was a determining factor in food choices. The respondents with longer seniority reported more frequent consumption of products bought during work hours and use of McDonald’s restaurants in general. Although almost half of the respondents were aware of the negative health eff ects of fast food, they did not limit its consumption. It appears essential to introduce health education for the surveyed group.

    The complaints and dietary habits of sixteen patients with gastritis and fourteen with undefined abdominal pain were studied by recording method. The results showed that the symptoms of the patients with gastritis and undefined abdominal pain were similar and mostly postprandial and they can be regarded as local (abdominal pain, meteorism, discomfort and heartburn) and/or general (sweating, nausea and faintness). The patients have variations of the symptomatic and asymptomatic periods. The symptomatic patients with gastritis have significantly higher number of daily meals than the asymptomatic patients with gastritis. The daily intake of food, energy and nutrients are low especially in the symptomatic patients with gastritis. It is concluded that the symptoms experienced by the patients with gastritis or undefined abdominal pain are related to the eating so that the daily dietary habits are disturbed. The produced a low intake of food, energy and nutrients especially in the patients with symptomatic gastritis.

    Mongolians are known to have relatively short life expectancy. In order to examine the role of dietary habits in the early aging of Mongolians, the food intake inquiry, anthropometric measurements and blood clinical tests were performed for 365 healthy inhabitants in Murun, a northern Mongolia city, and compared to those of Japanese. Murun inhibitants were found to have a characteristic dietary habit of taking large amounts of meat, milk, dairy products and wheat flour products, in contrast little vegetables, fruits and fishes. The daily calorie intake of the adults was estimated to be 2,525 kcal, and the fat/total calorie ratio was calculated 33.7%, about 1.3-fold higher than that of Japanese. The intake ratio of fatty acid from the Mongolian foods, saturated : mono-unsaturated : poly-unsaturated fatty acids (PUFA) ratio, was 10.3 : 7.8 : 3.0. Results of blood clinical tests showed significantly higher levels of serum triglycerides, low-density lipoprotein cholesterol (LDL) and homocysteine, and lower levels of high-density lipoprotein cholesterol (HDL), n-3 PUFA, folic acid and adiponectin, in comparison with those of Japanese. In addition, the Mongolians were also found to have significantly high levels of oxidative stress markers, such as serum malondialdehyde-modified LDL (MDA-LDL), urinary 8-hydroxy-2'-deoxyguanosine (8-OHdG) and serum reactive oxygen metabolites (ROM). The serum ROM level in the Mongolians seemed to associate with their body fat ratio (pObesity was observed at a high incidence in the subjects over 30-year old, and over 40-year old their handgrip ability was markedly decreased. These findings suggest that in the Mongolians the dietary habits associate with their lifestyle-related diseases and early aging, and the improvement of dietary habits is an effective strategy for health promotion of the inhabitants.

    Full Text Available Background: Gastric cancer is the most common cancer in Iran. Helicobacter pylori (HP and diet are both risk factors for this cancer. The way HP and diet affect each other may be important in controlling this high prevalent cancer. Few researches have been performed in this field around the world. The present study was designed to assess this relationship. Methods: A descriptive - cross sectional study performed in Tabriz. 86 samples were recruited from patients referred to" Tabriz gastrointestinal and liver research center" .A demographic and a food frequency questionnaire were filled in for each subject. After upper GI endoscopy a tissue sample from an antrum was sent to the pathology lab and data analyzed using non parametric tests.Results: Helicobacter Pylori infection rate was 42.6% according to pathologic results. A direct association was found between weekly consumption of fish (P=0.007, water (P=0.016 and green pepper (P=0.01 and HP infection. There was a negative relationship between the amount of tea (P=0.046 and tuna fish (P=0.046 consumed per week and HP infection. The severity of infection was direct associated with weekly consumption of fish (P=0.001 green pepper (P=0.045 and water (P=0.001 indirect associated with the amount of tuna fish (P=0.011 and sugar (P=0.044.Conclusions: This study suggests that there is a possibility that some dietary factors such as fish (except Tuna Fish, green pepper and water may reduce the chance of H.P and severity of this infection. However due to limitations of this study, larger and more accurately designed studies are necessary before any definite conclusion can be drawn.

    Full Text Available Abstract Background Few lifestyle factors have been simultaneously studied and reported for Saudi adolescents. Therefore, the purpose of the present study was to report on the prevalence of physical activity, sedentary behaviors and dietary habits among Saudi adolescents and to examine the interrelationships among these factors using representative samples drawn from three major cities in Saudi Arabia. Methods This school-based cross-sectional study was conducted during the years 2009-2010 in three cities: Al-Khobar, Jeddah and Riyadh. The participants were 2908 secondary-school males (1401 and females (1507 aged 14-19 years, randomly selected using a multistage stratified sampling technique. Measurements included weight, height, sedentary behaviors (TV viewing, playing video games and computer use, physical activity using a validated questionnaire and dietary habits. Results A very high proportion (84% for males and 91.2% for females of Saudi adolescents spent more than 2 hours on screen time daily and almost half of the males and three-quarters of the females did not meet daily physical activity guidelines. The majority of adolescents did not have a daily intake of breakfast, fruit, vegetables and milk. Females were significantly (p p p p Conclusions The high prevalence of sedentary behaviors, physical inactivity and unhealthy dietary habits among Saudi adolescents is a major public health concern. There is an urgent need for national policy promoting active living and healthy eating and reducing sedentary behaviors among children and adolescents in Saudi Arabia.

    The changes in dietary habits and way of life of adolescents can lead to some nutrition problems. The purpose of this study was to compare dietary habits of children living in metropolitan and non-metropolitan areas regarding their physical characteristics, socio-economic milieu and educational level. A total of 737 students studying in the 6th, 7th and 8th grades of two different primary schools took part in the study. Data were collected by a questionnaire including dietary habits of participants. Furthermore, the weight and height of students were measured and their body mass index was calculated. During the study, while 4.3 percent of students living in the non-metropolitan area were found obese, this figure was 8.4 percent in the metropolitan area. A big majority of non-metropolitan students have breakfast and lunch at home. Metropolitan students not having lunch at home have their lunch at restaurants or school canteens and generally consume more snacks. The obesity risk of students participating in the study was found to be high. Intervention programs should be organized in order to inform the students about the importance of healthy nutrition and lead them to change their current consumption behavior.

    Dietary fiber intake might reduce cardiovascular risk factor levels and, in turn, might lower the long-term risk of cardiovascular disease (CVD). A total of 11,113 subjects, aged 20 to 79 years with no history of CVD, from the 2005 to 2010 National Health and Nutrition Examination Survey were included in the present study to examine associations of dietary fiber intake with predicted lifetime CVD risk and C-reactive protein levels. Dietary fiber intake showed a significant gradient association with the likelihood of having a low or an intermediate predicted lifetime CVD risk among young and middle-age adults. In fully adjusted multinomial logistic models, dietary fiber intake was related to a low lifetime CVD risk with an odds ratio of 2.71 (95% confidence interval 2.05 to 3.59) in the young adults and 2.13 (95% confidence interval 1.42 to 3.20) in the middle-age adults and was related to an intermediate lifetime risk of 2.65 (95% confidence interval 1.79 to 3.92) in the young and 1.98 (95% confidence interval 1.32 to 2.98) in the middle-age adults compared with a high lifetime risk. A significant inverse linear association was seen between dietary fiber intake and log-transformed C-reactive protein levels with a regression coefficient ± standard error of -0.18 ± 0.04 in the highest quartile of fiber intake compared with the lowest fiber intake. In conclusion, these data suggest that dietary fiber intake is independently associated with the predicted lifetime CVD risk, especially in young and middle-age adults. A greater amount of dietary fiber intake might be associated with lower C-reactive protein levels.

    There is a need for valid and comprehensive measures of parental influence on children's energy balance-related behaviours (EBRB). Such measures should be based on a theoretical framework, acknowledging the dynamic and complex nature of interactions occurring within a family. The aim of the Family & Dietary habits (F&D) project was to develop a conceptual framework identifying important and changeable family processes influencing dietary behaviours of 13-15 year olds. A second aim was to develop valid and reliable questionnaires for adolescents and their parents (both mothers and fathers) measuring these processes. A stepwise approach was used; (1) preparation of scope and structure, (2) development of the F&D questionnaires, (3) the conducting of pilot studies and (4) the conducting of validation studies (assessing internal reliability, test-retest reliability and confirmatory factor analysis) using data from a cross-sectional study. The conceptual framework includes psychosocial concepts such as family functioning, cohesion, conflicts, communication, work-family stress, parental practices and parental style. The physical characteristics of the home environment include accessibility and availability of different food items, while family meals are the sociocultural setting included. Individual characteristics measured are dietary intake (vegetables and sugar-sweetened beverages) and adolescents' impulsivity. The F&D questionnaires developed were tested in a test-retest (54 adolescents and 44 of their parents) and in a cross-sectional survey including 440 adolescents (13-15 year olds), 242 mothers and 155 fathers. The samples appear to be relatively representative for Norwegian adolescents and parents. For adolescents, mothers and fathers, the test-retest reliability of the dietary intake, frequencies of (family) meals, work-family stress and communication variables was satisfactory (ICC: 0.53-0.99). Barratt Impulsiveness Scale-Brief (BIS-Brief) was included

    AIM: To investigate the angiographic characteristics of coronary artery in males with long-term alcohol habit. METHODS: Included in this study were males who underwent coronary angiography from July 2008 to July 2012 in our hospital and were found to have no coronary artery stenosis and no diseases that cause coronary artery ectasis. According to their alcohol consumption, subjects were divided into three groups: heavy alcohol consumption, light/moderate alcohol consumption, and no alcohol consumption. The results of coronary angiography were analyzed and compared. RESULTS: The coronary artery diameter in heavy alcohol consumption group was significantly wider than in the light/moderate alcohol group and no alcohol group ( P < 0. 05 ). In the heavy alcohol consumption group, the rate of coronary artery ecta-sias (18% ) was significantly higher than those in the light/moderate alcohol group (2% ) and no alcohol group (l%)(P<0. 05) and the rate of slow flow (29% ) was significantly higher than in the light/moderate alcohol group (4% ) and no alcohol group (3% ) (P <0. 05). CONCLUSION: Long-term heavy alcohol consumption can change the normal form of the coronary artery and increase the incidence of coronary artery dilatation and slow blood flow rate, thus affecting myocardial blood supply.%目的:初步探讨长期饮酒对男性冠状动脉内径及血流速度的影响.方法:选择2008年7月~2012年7月在我院行冠脉造影,无冠脉粥样硬化狭窄病变的所有男性为研究对象.根据既往是否饮酒及饮酒程度分为3组:重度饮酒组(38例)、轻中度饮酒组(84例)和不饮酒组(67例).对比分析各组冠状动脉造影结果.结果:重度饮酒组左主干、左前降支主支、回旋支主支、右冠状动脉主支内径均较轻中度饮酒组与不饮酒组显著增宽(均P<0.05);轻中度饮酒组与不饮酒组无统计学差异.重度饮酒组冠脉扩张病变率(18%)较轻中度饮酒组(2%)与不饮酒组(1

    The essential amino acid l-tryptophan (Trp) is the immediate precursor of the neurotransmitter serotonin (5-HT). Supplementing Trp through diet has been shown to suppress the neuroendocrine stress response in vertebrates including teleosts. In salmonid fish, adjusting to the social environment...... as well as habituation to seawater involves the neuroendocrine stress response, suggesting that such environmental factors may modulate the stress-reducing effects of Trp.

    This paper reports findings from a cross-sectional survey carried out in April-May 2006 among international students enrolled at Ghent University in Belgium. The aim of the study was to assess their knowledge and attitudes related to nutrition, perceived changes in dietary habits, perceived barriers to healthy eating and the determinants of dietary changes since their arrival in Belgium. In total, 235 students from 60 countries participated. Following the reported dietary changes, which were factor-analyzed into "less energy-dense" foods, "more fruits and vegetables" and "less processed" foods, three clusters could be identified. Cluster 1 composed of students who increased their fruits, vegetables and fiber intake. Cluster 2, the largest, reported dietary changes overall and in particular towards less processed foods. Cluster 3 composed of students who changed in the main towards less energy-dense foods. Gender differences were observed in healthy dietary changes, particularly in males. Healthier choices were hindered by a perceived unavailability of healthy food products. Gender and availability of healthy foods should be taken into consideration when informing temporal migration populations, such as international students in this study, about the healthy food options available during their stay in a different cultural, food and dietary environment.

    To identify the role of dietary habits (type of diet, skipping meals, snacking in-between meals and frequency of visits to fast food restaurants) in caries occurrence and severity. To explore the correlation between frequency of intake of selected foods and dental caries. A cross-sectional study was carried out on adolescent children (n = 916) of age 13-19, following a two-stage random sampling technique. Data were collected using a pretested questionnaire. Questionnaire included demographic details, dietary habits of children and food frequency table that listed selected food items. The dependent variable-dental caries was measured using the decayed, missing, filled teeth (DMFT) index. The prevalence of dental caries in this study population was 36.7% (95% confidence interval: 33.58-39.82). The mean DMFT was 1.01 (±1.74). No statistically significant difference found between caries occurrence and type of diet (P = 0.07), skipping meals (P = 0.86), frequency of eating in fast food stalls (0.86) and snacking in between meals (0.08). Mean DMFT values were higher among nonvegetarians and among children who had the habit of snacking in between meals. Frequency of intake of selected food items showed that mean frequency intake of carbonated drinks and confectionery was higher among children who presented with caries when compared to caries-free children (P = 0.000). Significant correlation found between mean DMFT and mean frequency intake of carbonated drinks and confectionery. Odds ratios were calculated for the same for frequency ≥4 times/day for confectionery and ≥4/week for carbonated drinks and results discussed. Frequent intake of carbonated drinks and confectionery is harmful to oral health that eventually reflects on general health. Educating the adolescent children on healthy dietary habits should be put in the forefront.

    Full Text Available INTRODUCTION: The efficacy of interventions against children malnutrition crucially depends on a myriad of factors other than the simple food intake, that must be carefully studied in order to plan a balanced policy. The relation between dietary patterns and growth is at the very heart of the problem, especially in consideration of the fact that dietary pattern involves dimension other than pure caloric intake in its definition. In this work we investigated the relations between dietary pattern and growth comparing children from a rural and a urban area in Andean Peru, in terms of food habits and anthropometric variables to develop a model usable in context interventions against malnutrition. MATERIAL AND METHODS: A sample of 159 children (80 from urban, 79 from rural area, aged from 4 to 120 months (72.7 ± 37.5 SD was collected. The data were investigated by a multidimensional (principal component analysis followed by inferential approach analysis to correlate the different hidden dimensions of both anthropometric and dietary observables. The correlation between these dimensions (in the form of principal components were computed and contrasted with the effects of age and urban/rural environments. RESULTS: Caloric intake and growth were not linearly correlated in our data set. Moreover urban and rural environment were demonstrated to show very different patterns of both dietary and anthropometric variables pointing to the marked effect of dietary habits and demographic composition of the analyzed populations. The relation between malnutrition and overweight was at the same time demonstrated to follow a strict area dependent distribution.

    Quantitative reconstruction of paleodiet by means of sequential sampling and carbon isotope analysis in hypsodont tooth enamel requires a precise knowledge of the isotopic enrichment between dietary carbon and carbon from enamel apatite ( ɛD-E), as well as of the timing and duration of the enamel mineralization process (amelogenesis). To better constrain these parameters, we performed a series of controlled feeding experiments on sheep ranging in age from 6 to 24 months-old. Twenty-eight lambs and 14 ewes were fed isotopically distinct diets for different periods of time, and then slaughtered, allowing the timing and rate of molar growth to be determined. High resolution sampling and stable carbon isotope analysis of breath CO 2 performed on six individuals following a diet-switch showed that 70-90% of dietary carbon had turned over in less than 24 h. Sequential sampling and carbon isotopic analysis was performed on the first (M 1) and second (M 2) lower molars of four lambs as well as on the third lower molar (M 3) of 11 ewes. The changes in diet were recorded in all molars. We found that the length of enamel matrix apposition is approximately one-quarter of the final tooth length during crown extension, and that enamel maturation spans slightly less than 3 months in M 1, and 4 months in M 2 and M 3. Portions of enamel in equilibrium with dietary carbon were used to calculate ɛD-E values. Animals on grass silage diets had values similar to previous observations, whereas animal switched to pelleted corn diets had values ca. 4‰ lower, a pattern consistent with lower methane production observed for animals fed concentrate diets. The tooth enamel forward model of Passey and Cerling (2002) closely predicted the amplitude of isotope changes recorded in tooth enamel, but slightly underestimated the rate of isotope change, suggesting that the rate of accumulation of carbonate during maturation may not be constant over time. Although stable isotope profiles in tooth

    Omega-3 (n-3) fatty acids are important for adequate brain function and cognition. The aim of the present study was to evaluate how n-3 fatty acids influence the persistence of long-term memory (LTM) in an aversive memory task and to explore the putative mechanism involved. Female rats received isocaloric diets that included n-3 (n-3 group) or not (D group). The adult litters were subjected to an inhibitory avoidance task (0.7 mA, 1.0 seconds foot shock) to elicit persistent LTM. Twelve hours after the training session, the fatty acid profile and the brain derived neurotrophic factor (BDNF) content of the dorsal hippocampus were assessed. In addition, we measured the activation of the NR2B subunit of the N-methyl-d-aspartate (NMDA) receptor and the SRC family protein Fyn. Despite pronounced learning in both groups, the persistence of LTM was abolished in the D group 7 days after the training session. We also observed that the D group presented reductions in hippocampal DHA (22:6 n-3) and BDNF content. Twelve hours after the training session, the D group showed decreased NR2B and Fyn phosphorylation in the dorsal hippocampus, with no change in the total content of these proteins. Further, there was a decrease in the interaction of Fyn with NR2B in the D group, as observed by co-immunoprecipitation. Taken together, these data suggest that n-3 fatty acids influence the persistence of LTM by maintaining adequate levels of DHA and BDNF as well as by influencing the activation of NR2B and Fyn during the period of memory formation.

    Recent research has indicated that increased vulnerability to oxidative stress may be the major factor involved in CNS functional declines in aging and age-related neurodegenerative diseases, and that antioxidants, e.g., vitamin E, may ameliorate or prevent these declines. Present studies examined whether long-term feeding of Fischer 344 rats, beginning when the rats were 6 months of age and continuing for 8 months, with diets supplemented with a fruit or vegetable extract identified as being high in antioxidant activity, could prevent the age-related induction of receptor-mediated signal transduction deficits that might have a behavioral component. Thus, the following parameters were examined: (1) oxotremorine-enhanced striatal dopamine release (OX-K+-ERDA), (2) cerebellar beta receptor augmentation of GABA responding, (3) striatal synaptosomal 45Ca2+ clearance, (4) carbachol-stimulated GTPase activity, and (5) Morris water maze performance. The rats were given control diets or those supplemented with strawberry extracts (SE), 9.5 gm/kg dried aqueous extract (DAE), spinach (SPN 6.4 gm/kg DAE), or vitamin E (500 IU/kg). Results indicated that SPN-fed rats demonstrated the greatest retardation of age-effects on all parameters except GTPase activity, on which SE had the greatest effect, whereas SE and vitamin E showed significant but equal protection against these age-induced deficits on the other parameters. For example, OX-K+-ERDA enhancement was four times greater in the SPN group than in controls. Thus, phytochemicals present in antioxidant-rich foods such as spinach may be beneficial in retarding functional age-related CNS and cognitive behavioral deficits and, perhaps, may have some benefit in neurodegenerative disease.

    Full Text Available Background: Maintaining an adequate health status and appropriate lifestyles during pregnancy is of great importance to prevent adverse outcomes for both mother and baby. The present study aimed to assess the nutritional status, socio-demographic features, lifestyle behaviors and dietary habits of pregnant women in Spain, and to identify the influence of parity on these profiles. Methods: This cross-sectional study included pregnant women from regions all over Spain. The information was collected through a 40 item questionnaire, previously validated, by community health professionals. Results: The 5,087 pregnant women analyzed had an average age of 31.9 years with an adequate nutritional status. The distribution of the sample was 56% nulliparous and 44% multiparous. The nulliparous reported a better self-perceived health status and nutritional balance, and a lower incidence of gestational diabetes mellitus. However, the multiparous showed healthier lifestyle habits (lower rates of smoking and alcohol consumption and more physically active patterns. Regarding diet, nulliparous pregnant women consumed more dairy products, fresh fruit and nuts, and less bread, rice/pasta/potatoes, meat, sausage and buns/pastries than multiparous pregnant women. Conclusions: Differences between analyzed patterns were observed in anthropometrical variables, lifestyle behaviors and dietary habits, which may require different nutritional messages to nulliparous as compared to multiparous from a public health point of view.

    The present study investigated the effects of dietary trace mineral (Cu, Fe, Mn, and Zn) supplemental strategies on liver oxidative stress, endoplasmic reticulum stress, inflammation, and apoptosis of pigs. A total of 96 Duroc × Landrace × Yorkshire (DLY) piglets were randomly divided into four groups: considered or not considered the trace mineral concentrations in basal diet, and then added to the requirements proposed by NRC (2012) (+B/NR or -B/NR); and considered or not considered the basal diet's trace mineral concentrations and then added to the level of commercial trace mineral supplement (+B/PL or -B/PL). Pigs were fed from 6.5 to 115 kg. Compared with +B/NR diets, -B/PL diets increased serum aspartate aminotransferase (AST) and alanine aminotransferase (ALT) concentrations (P pigs fed -B/PL diets increased CCAAT/enhancer-binding protein homologous protein (CHOP), eukaryotic initiation factor-2α (eIF-2a), interleukin-6(IL-6), B-cell lymphoma leukemia-2-associated X protein (Bax), and caspase-3, caspase-8, and caspase-9 gene expression (P dietary mineral exposure with the commercial supplement level could cause harm to the structure and metabolic function of liver in pigs.

    The long-term effects of dietary strategies designed to combat the metabolic syndrome (MetS) remain unknown. The present study evaluated the effectiveness of a new dietary strategy based on macronutrient distribution, antioxidant capacity and meal frequency (MEtabolic Syndrome REduction in NAvarra (RESMENA) diet) for the treatment of the MetS when compared with the American Heart Association guidelines, used as Control. Subjects with the MetS (fifty-two men and forty-one women, age 49 (se 1) years, BMI 36·11 (se 0·5) kg/m²) were randomly assigned to one of two dietary groups. After a 2-month nutritional-learning intervention period, during which a nutritional assessment was made for the participants every 15 d, a 4-month self-control period began. No significant differences were found between the groups concerning anthropometry, but only the RESMENA group exhibited a significant decrease in body weight ( - 1·7%; P= 0·018), BMI ( - 1·7%; P= 0·019), waist circumference ( - 1·8%; P= 0·021), waist:hip ratio ( - 1·4%; P= 0·035) and android fat mass ( - 6·9%; P= 0·008). The RESMENA group exhibited a significant decrease in alanine aminotransferase and aspartate aminotransferase (AST) concentrations ( - 26·8%; P= 0·008 and - 14·0%; P= 0·018, respectively), while the Control group exhibited a significant increase in glucose (7·9%; P= 0·011), AST (11·3%; P= 0·045) and uric acid (9·0%; P< 0·001) concentrations. LDL-cholesterol (LDL-C) concentrations were increased (Control group: 34·4%; P< 0·001 and RESMENA group: 33·8%; P< 0·001), but interestingly so were the LDL-C:apoB ratio (Control group: 28·7%; P< 0·001, RESMENA group: 17·1%; P= 0·009) and HDL-cholesterol concentrations (Control group: 21·1%; P< 0·001, RESMENA group: 8·7; P= 0·001). Fibre was the dietary component that most contributed to the improvement of anthropometry, while body-weight loss explained changes in some biochemical markers. In conclusion, the RESMENA diet is a good

    We investigated temporal changes of perfluoroalkyl carboxylic acids (PFCAs) with 8-14 carbon atoms (C8 to C14) in duplicate diet and serum samples in Japan. The sum dietary intakes of PFCAs (C8 to C13) in the Kansai and Tohoku region were highest in the 2010s (mean; 177 ng/day for Kansai, 107 ng/day for Tohoku) followed by the 2000s (77 ng/day for Kansai, 34 ng/day for Tohoku) and the 1990s (53 ng/day for Kansai, 58 ng/day for Tohoku), then the 1980s (19 ng/day for Kansai, 23 ng/day for Tohoku). The sum of the serum concentartions (C8 to C13) was also highest in the 2010s (mean; 17 ng/mL for Kansai, 7.4 ng/mL for Tohoku), followed by the 2000s (12 ng/mL for Kansai, 6.3 ng/mL for Tohoku), then the 1990s (6.8 ng/mL for Kansai, 5.5 mg/mL for Tohoku) and the 1980s (3.8 ng/mL for Kansai, 0.4 ng/mL for Tohoku). A positive correlation was observed between dietary intakes and serum concentration for C8 to C11 (r = 0.94, p < 0.05 for C8; r = 0.80, p < 0.05 for C9; r = 0.98, p < 0.05 for C10; and r = 0.84, p < 0.05 for C11). The levels of C8, C9 and C10 in serum and dietary intake in the 2010s were much higher in Kansai than those in Tohoku, although those of C11 did not show such differences. Kansai has a fluoropolymer manufacture known as a specific source of PFOA (C8), and is more urbanized than Tohoku, which may be attributed to the higher levels of PFCAs (C8 to C10). On the other hand, C11 is common to residents in Kansai and Tohoku.

    Nutritional habits and physical activity influence the health status of young adults. In this study, we engaged a group of 151 students from a medical university (90 female and 61 male subjects). Anthropometric parameters, dietary habits (a 7-day dietary recall), and level of physical activity were measured. It was found that the daily food rations of female (F) and male (M) students were improperly balanced and characterized by high amount of total and animal protein, phosphorus, vitamin A, cholesterol, and insufficient intake of carbohydrates, dietary fiber, and vitamin C. Female subjects consumed low amounts of total fat and calcium. The intake of protein (total and animal), fat, phosphorus, and cholesterol correlated with higher body mass. The physical activity of the students was found to be higher than the average physical activity of the European Union populations, and a general tendency of lowering level of physical activity with age was observed. Students with the highest level of physical activity (MET > 1500) consumed lower amounts of simple carbohydrates (galactose and saccharose) when compared to students with lower physical activity (MET students and they should be encouraged to participate in high level of physical activity so as to promote good health status.

    Transgenic (Tg) mice, which possess an amyloid precursor protein (APP) gene mutation, develop extracellular amyloid β (Aβ) deposition in the brain, and severe memory and behavioral deficits with age. These mice serve as an important animal model for testing the efficacy of novel drug candidates for the treatment and management of symptoms of Alzheimer's disease (AD). Several reports have suggested that oxidative stress is the underlying cause of Aβ neurotoxicity in AD. Pomegranates contain very high levels of antioxidants and several medicinal properties that may be useful for improving quality of life in individuals with AD. The aim of this study was to investigate the effect of dietary supplementation of Omani pomegranate extract on memory, anxiety, and learning skills in an AD mouse model possessing the double Swedish APP mutation (APPsw/Tg2576). The experimental groups of APP-Tg mice from the age of 4 mo were fed a custom mixed diet (pellets) containing 4% pomegranate. We assessed spatial memory and learning ability, psychomotor coordination, and anxiety-related behavior in Tg and wild-type mice at the age of 4 to 5 mo and 18 to 19 mo using the Morris water maze test, rotarod performance test, elevated plus-maze test, and open field test. APPsw/Tg2576 mice that were fed a standard chow diet without pomegranates showed significant memory deficits, increased anxiety-related behavior, and severe impairment in spatial learning ability, position discrimination learning ability, and motor coordination compared with the wild-type mice on the same diet, at the age of 18 to 19 mo. In contrast, APPsw/Tg2576 mice that were fed a diet containing 4% pomegranates showed significant improvements in memory, learning, locomotor function, as well as reduction in anxiety, compared with APPsw/Tg2576 mice fed the standard chow diet. Our results suggest that dietary supplementation with pomegranates may slow the progression of cognitive and behavioral impairments in AD. Copyright

    This study was conducted to assess improvements in nutritional status following the application of nutrition education to elderly patients in a long-term care hospital. The study was carried out from January to May 2009, during which a preliminary survey, a pretest, the application of nutrition education, and a post-test were applied in stages. The number of subjects at pretest was 81, and the number of participants included in the final analysis was 61 (18 men, 43 women), all of whom participated in both the nutrition education program and the post-test. The survey consisted of general demographic items, health behaviors, dietary behaviors, the Nutrition Screening Initiative checklist, and nutrient intake assessment (24 hour recall method). The nutrition education program lasted for four weeks. It included a basic education program, provided once a week, and mini-education program, which was offered daily during lunch times. The survey was conducted before and after the education program using the same assessment method, although some items were included only at pretest. When analyzing the changes in elderly patients after the nutritional education program, we found that, among subjective dietary behaviors, self-rated perceptions of health (P nutritional risk levels decreased. In terms of nutrient intake, subjects' intake of energy, protein, fat, carbohydrate, calcium, phosphorus, iron, vitamin A, thiamin, riboflavin, niacin, and vitamin C all increased significantly (P nutritional education is effective in improving the nutritional status of elderly patients. We hope that the results of this study can be used as preliminary data for establishing guidelines for nutrition management tailored to elderly patients in long-term care hospitals.

    The aim of this study was to evaluate the effects of two dietary supplements (monensin and a live yeast culture) on acid-base balance in steers maintained in a commercial feedlot system, considering effects over the growing period (14 to 23 weeks of age). A 63-day feedlot study was performed using 42 double-muscled Belgian Blue steers. Steers were allotted randomly to one of the three study groups: (1) control group [no supplementation, C], (2) monensin supplementation [MON] at a concentration of 30 mg/kg (DM basis), and (3) live Saccharomyces cerevisiae strain supplementation [SACC] at a dose of 500 mg/kg (DM basis). Venous blood samples were collected for the measurement of acid-base parameters and L-lactate. Production parameters were also used as a complementary tool for understanding the internal changes associated with supplementation. Our results show that during the study period no statistical differences were observed between supplemented and control steers, although non-supplemented animals tended to gain more efficiently than those fed monensin or yeast. Nevertheless, taking into account blood parameters, these control animals showed a greater risk of acid overload due to a more marked decline in blood buffer levels over time in comparison with supplemented steers although no differences were observed between monensin or yeast supplemented animals. Additionally, significant effect of supplementation was observed in packed cell volume (PCV) values.

    We have previously reported that Amadori compounds exert anti-diabetic effects by lowering sucrose-induced hyperglycemia in normal Sprague-Dawley rats. In the present study we extended our recent findings to evaluate whether α-glucosidase inhibitor arginyl-fructose (AF) lowers blood glucose level in diabetic db/db mice, a genetic model for type 2 diabetes. The db/db mice were randomly assigned to high-carbohydrate diets (66.1% corn starch) with and without AF (4% in the diet) for 6 weeks. Changes in body weight, blood glucose level, and food intake were measured daily for 42 days. Dietary supplementation of AF resulted in a significant decrease of blood glucose level (p HbA1c, a better indicator of plasma glucose concentration over prolonged periods of time, was also significantly decreased for 6-week period (p diet), a positive control, also significantly alleviated the level of blood glucose, HbA1c, and body weight. These results indicate that AF Maillard reaction product improves postprandial hyperglycemia by suppressing glucose absorption as well as decreasing HbA1c level.

    Bats are among the most conspicuous mammals with extraordinary adaptations. They play a key role in the ecosystem. Frugivorous bats are important seed dispersing agents that help in maintaining forest tree diversity, while insectivorous bats are natural insect pest control agents. Several previous reports suggest that bats are reservoir of viruses; nonetheless their bacterial counterparts are relatively less explored. The present study describes the microbial diversity associated with the intestine of bats from different regions of India. Our observations stipulate that there is substantial sharing of bacterial communities between the insectivorous and frugivorous bats, which signifies fairly large dietary overlap. We also observed the presence of higher abundance of Mycoplasma in Cynopterus species of bats, indicating possible Mycoplasma infection. Considering the scarcity of literature related to microbial communities of bat intestinal tract, this study can direct future microbial diversity studies in bats with reference to their dietary habits, host-bacteria interaction and zoonosis.

    The life-stage approach, which views the behaviours and exposures of an individual from the preconceptual situation of the parent through pregnancy, infancy, childhood and adolescence, and into the advancing years through adulthood, is the basis of analysis of strategies to improve long-term health. Among the behaviours of note is the dietary selection pattern, conditioning our exposure to nutrients and dietary constituents that influences growth, nutriture, cognitive and physical performance, and disease resistance and susceptibility. The African Diaspora created a population displaced from Africa to the Western Hemisphere as part of the African slave trade from the 16th to 18th centuries. It continues to manifest distinct dietary and lifestyle practices in the context of a health experience that is different both from the population in their African countries of origin and from the other ethnicities in their countries of displacement and current residence. Afro-Americans are more susceptible to a series of diseases and conditions including low birth weight, violence, and HIV/AIDS, as well as the non-communicable diseases: obesity, diabetes mellitus, cardiovascular disease, hypertension, stroke, renal failure, breast cancer, prostate cancer and lead poisoning. The differential nature of dietary practices are conditioned at times by the poverty and marginalisation of the populace, resulting in either disadvantageous or beneficial outcomes relative to others' eating habits. Serious consideration must be given to the possibility that ethnic difference give rise to different requirements and tolerances for essential nutrients and distinct protective or adverse responses to foods and dietary substances. The major challenges to health improvement for the African Diaspora is coming to grips with the policy and programmatic nuances of differential treatment and the effecting the behavioural changes that would be needed in a population skeptical of the motives of media and

    Objective To examine weight change by diabetes status among participants receiving a Mediterranean-style diet, physical activity, and weight loss intervention adapted for delivery in the southeastern USA, where rates of cardiovascular disease (CVD) are disproportionately high. Research design and methods The intervention included: Phase I (months 1–6), an individually tailored intervention promoting a Mediterranean-style dietary pattern and increased walking; Phase II (months 7–12), option of a 16-week weight loss intervention for those with BMI≥25 kg/m2 offered as 16 weekly group sessions or 5 group sessions and 10 phone calls, or a lifestyle maintenance intervention; and Phase III (months 13–24), weight loss maintenance intervention for those losing ≥8 pounds with all others receiving a lifestyle maintenance intervention. Weight change was assessed at 6, 12, and 24-month follow-up. Results Baseline characteristics (n=339): mean age 56, 77% female, 65% African-American, 124 (37%) with diabetes; mean weight 103 kg for those with diabetes and 95 kg for those without. Among participants with diabetes, average weight change was −1.2 kg (95% CI −2.1 to −0.4) at 6 months (n=92), −1.5 kg (95% CI −2.9 to −0.2) at 12 months (n=96), and −3.7 kg (95% CI −5.2 to −2.1) at 24 months (n=93). Among those without diabetes, weight change was −0.4 kg (95% CI −1.4 to 0.6) at 24 months (n=154). Conclusions Participants with diabetes experienced sustained weight loss at 24-month follow-up. High-risk US populations with diabetes may experience clinically important weight loss from this type of lifestyle intervention. Trial registration number NCT01433484.

    Full Text Available Abstract Background The average life span of Mongolians is 62 years for males and 69 years for females. This life span is about 16 years shorter than that of Japanese. Mongolian people generally eat meat, fat and diary products but less vegetables or fruit. Thus, we investigated the state of oxidative stress and dietary habits of Mongolians. Methods The investigation was performed in Murun city in the northwest area of Mongolia. A total of 164 healthy subjects (24–66 y were enrolled. As a marker of reactive oxygen species, the levels of reactive oxygen metabolites (ROM were measured using the d-ROM test. Interviews about dietary habits were performed using the Food Frequency Questionnaire established by the Kagawa Nutrition University. Results ROM levels were 429.7 ± 95.2 Carr U for Murun subjects, whereas Japanese people (n = 220, 21–98 y showed 335.3 ± 59.8 (p Conclusion Murun subjects may be in high oxidative stress, which may have a relationship with early ageing and several diseases, ultimately resulting in their short life span. In order to increase antioxidant capacity and suppress overproduction of ROM, antioxidant food intake is recommended.

    Full Text Available Introduction: Eating habits of various age and professional groups has been evaluated. However, there is little information on the dietary habits of soldiers. The aim of this study is to associate eating habits with the normal body mass index (BMI in Chilean soldiers from Buin Regiment. Material and Methods: 412 soldiers were evaluated. Food survey and anthropometric evaluation was applied to each soldier. It was considered a normal BMI when the subject was between 18.5-24.9kg/m2, overweight between 25.0-29.9kg/m2 and obesity ≥30.0kg/m2, according to the WHO recommendations. Results: 41.2% of the soldiers show a normal BMI, 43.1% present overweight and 15.7% exhibit obesity. Only 5% meet the dairy and fruit Chilean recommendations, however almost 40% of them consume 1time/day (OR:0.41; IC95%:0.19-0.88 and legume consumption (>1time/week (OR:0.29; IC95%:0.14-0.60. Conclusions: A low consumption of dairy products, fruits, vegetables and legumes is noted, and a high consumption of sweetened beverages. In addition, intake of dairy products and legumes is related with a normal BMI.

    Full Text Available There is a shift worldwide towards a diet that is high in processed foods and low in fiber, leading to a corresponding increase in degenerative diseases. These diseases are interrelated with lifestyles and especially with diets. The aim of this study was to investigate the eating habit differences between two generations of mothers and daughters and their tendency towards modern foods.In this cross-sectional survey, the data were gathered using structured questionnaires. The sample of the study includes 618 women in Shiraz City (309 mothers and 309 daughters selected through stratified random sampling. Data analysis was carried out using the SPSS software.In the mothers' generation, around 80% showed a traditional nutritional pattern while in the young generation more than 50% had a modern or close to modern pattern of nutrition (P ≤ 0.05. The findings confirmed a significant difference in dietary habits among the two generations. For both generations, nutrition pattern was significantly different in terms of social class, weight control, education, using mass communication, and physical activities (P ≤ 0.05.Iran is currently experiencing a nutrition transition. The current inappropriate habits in the lifestyles of the girls' in Shiraz are a health threat for them, and it will increase the risk of non-communicable diseases. Therefore, policy makers have to set new agenda to increase the nutritional knowledge of the population.

    Full Text Available Maintenance of proper health and prevention of diseases of civilization are now significant public health problems. Nutrition is an important factor in the development of youth, as well as the current and future state of health. The aim of the study was to show the benefits of the application of cluster analysis to assess the dietary habits of high school students. The survey was carried out on 1,631 eighteen-year-old students in seven randomly selected secondary schools in Bialystok using a self-prepared anonymous questionnaire. An evaluation of the time of day meals were eaten and the number of meals consumed was made for the surveyed students. The cluster analysis allowed distinguishing characteristic structures of dietary habits in the observed population. Four clusters were identified, which were characterized by relative internal homogeneity and substantial variation in terms of the number of meals during the day and the time of their consumption. The most important characteristics of cluster 1 were cumulated food ration in 2 or 3 meals and long intervals between meals. Cluster 2 was characterized by eating the recommended number of 4 or 5 meals a day. In the 3rd cluster, students ate 3 meals a day with large intervals between them, and in the 4th they had four meals a day while maintaining proper intervals between them. In all clusters dietary mistakes occurred, but most of them were related to clusters 1 and 3. Cluster analysis allowed for the identification of major flaws in nutrition, which may include irregular eating and skipping meals, and indicated possible connections between eating patterns and disturbances of body weight in the examined population.

Sample and methodology: The population of the sample consisted of 138 adolescents, age range was between 14-19 years old: 67 males (48.6% and 71 females (51.4%. They were students at two public secondary schools in the city of Almería (Spain. In the first phase (15-30 september 2011 of this three-phase study, the nutritional status of the students was assessed by means of anthropometry. In the second phase (1 october 2012-15 june 2012, the students participated in an educational intervention that fomented awareness of the benefits derived from healthy eating habits and physical exercise. In the third and final phase (16-31 june 2012, the effectiveness of the intervention was evaluated. Results: After the intervention, statistically significant differences (p < 0.000 were found in relation to the nutritional status of all the students evaluated, regardless of their sex. In reference to the adoption of healthy habits after the intervention, statistical significant differences were observed in the Krece Plus test (p < 0.000 and in the practice of physical exercise (p = 0.006. In the case of sedentary leisure activities, there was also a statistically significant reduction (p < 0.000 in the number of hours spent watching television for both male and female subjects. Conclusion: The results of this study show the effectiveness of the contents, activities, and duration of this health education intervention to encourage the subjects to modify their dietary and exercise habits.

    Obesity among Saudi youth is a growing public health challenge. This cross-sectional study measured body mass index (BMI) and determined the eating habits and lifestyle of 107 randomly selected female adolescent students (age 12-15 years) at schools in Riyadh. The students' heights and weights were measured and a pre-tested questionnaire was used to collect data on diet and lifestyle. The majority of the students' families had monthly income > 10 000 riyals (US$ 1 = 3.75 riyals). About half the students (53.3%) were within normal weight, 28.6% were underweight, 12.4% overweight and 5.7% obese. The majority of the students did not have healthy dietary or exercise habits. There were no significant differences between BMI category and dietary pattern and lifestyle. Increasing educational programmes with healthy dietary concepts to improve the dietary pattern of female adolescents is recommended.

    The purpose of this study was to investigate the long-term effects of three model diets containing different fats, with or without a small amount of green tea extract (GTE), on plasma lipids and glucose, and liver lipids in mice. Male mice (2 months old) fed 10% fat diets with Western (W), Vegetarian (V), and Japanese (J) fat compositions with or without 0.03% GTE for 7 months. The concentrations of plasma and liver total cholesterol in animals fed the W diet were not significantly different from those fed the J diet. Plasma triacylglycerol (TG) concentrations were significantly different from one another in the following order: V > J > W diet groups. GTE supplementation significantly reduced plasma and liver TG content only in V diet group. Plasma glucose (Glu) concentrations were in the following order: W > V > J diet groups, and the GTE supplementation reduced the concentration of Glu in each diet group. The ratios of plasma n-6 to n-3 fatty acids were in the following order: V > W > J diet groups, regardless of GTE supplementation. These findings show the possibility that Japanese eating habits combined with drinking green tea might be a factor in preventing the onset of non-insulin-dependent diabetes mellitus.

    This paper describes dietary habits and attitudes toward body weight control of college women in Japan and examines their relationships with subjective symptoms of fatigue. We also discuss strategies to promote better diets among young adults. Self-reported questionnaires were distributed to 286 young women aged 18 to 25 years; 275 of these were analyzed. The study found that more than half of the women were concerned about nutritional balance and calories. Yet thirty percent ate "a single-item meal (i.e., bread, rice bowl, noodles) two or more times a day," while roughly one half skipped breakfast "sometimes" or "always." A majority ate vegetables "almost never" and consumed instant foods, confectionery, or sugary drinks "almost daily." Subjective symptoms of fatigue were significantly correlated with a higher frequency of irregular meal-taking, single-item meals, between-meal snacking, missed breakfasts, non-vegetable diets, non-fruit diets, and instant foods and confectionery. About sixty percent of the women in the study considered their bodies to be "slightly fat or overweight" while 79.5% indicated a desire to "lose weight". On average, the participants' ideal BMI was 18.7 (+/- 1.2) while the ideal body weight was 47.2 (+/- 4.1) kg, approximately 4 kg under actual average body weight. Subjective symptoms of fatigue were stronger among women who considered themselves "slightly fat or overweight". Likewise, symptoms were stronger to the extent that a participant's ideal BMI was below her actual BMI. Many women in this study desired to lose weight although they were not overweight by objective measures. The study suggests that subjective symptoms of fatigue are not the result of individual dietary habits, but rather of a lifestyle that reach to series of dietary habits connected to subjective symptoms of fatigue. The study also confirms the importance both of encouraging young women not just to eat well but to lead lifestyles in which they do not skip meals and

    Full Text Available To assess the association between unhealthy dietary habits and cognition in older adults from Southern Brazil.This cross-sectional study analyzed data from the second wave of a population- and household-based epidemiological survey (2013-2014 conducted in the city of Florianópolis. A total of 1,197 older adults (778 women over 60 years old participated in the study. Cognition, the dependent variable, was measured by the Mini-Mental State Examination (MMSE. The independent variables were the following indicators of unhealthy dietary habits: low intake of fruits and vegetables (≤ 4 servings/day; fish (< 1 serving/week; and habitual fatty meat intake (yes/no. Adjustments were made for age, education level, income, smoking status, alcohol intake, leisure-time physical activity, depression symptoms, chronic diseases, and body mass index. Simple and multiple linear regression analyses were performed, considering sampling weights and stratification by gender.The mean MMSE scores for men and women were 25.15 ± 5.56 and 24.26 ± 5.68, respectively (p = 0.009. After adjustments, in women low fruit and vegetable intake (≤ 4 servings/day was independently associated with the lowest MMSE scores. No associations were found in men. Additionally, women's mean MMSE scores increased as their daily frequency of fruit and vegetable intake increased (p = 0.001.Women with low fruit and vegetable intake according to the World Health Organization (WHO have lower cognition scores. Regular intake of fruits, vegetables, and fish in exchange of fatty meats may be a viable public policy strategy to preserve cognition in aging.

    Background: Although nutritional status of children and adolescents is of great concern various interventions and modifications aiming at promotion of healthy eating behaviors have limited impact due to insufficient understanding of dietary habits between different age groups and genders. The aim of this study in not only evaluation of nutritional knowledge, practice, and dietary habits of primary school and junior high school students in Isfahan province, but also this research explore crucial differences regarding gender and living area of the above-mentioned population in Iran. Methods: This cross-sectional study was conducted on 4700 primary school and junior high school pupils in Isfahan province. Data were collected through standard 24-h recall food frequency questionnaire and researcher-designed questionnaire. Independent t-test was applied for comparison of mean values of total units of consumed food materials. Qualitative variables were compared by using the Chi-square test. Data were analyzed by ACCESS 2010 and SPSS 18 software. Results: Nutritional knowledge of female pupils and junior high school students was higher than their male and elementary school students respectively; still, theses superiorities did not lead to higher practice score. Bread and cereals group received daily intakes in accordance with food and drug administration (FDA) recommendations. Indeed, vegetables, milk, and dairy products, as well as meat daily intakes, were lower than the FDA recommendation, whereas fats, oils, and sugars intakes were higher. In comparison to females, male participants had significantly lower consumption of vegetables and fruits whilst they had a higher intake of carbohydrates, fats, and meats. Conclusions: Our results showed that adolescents failed to meet sufficient nutritional requirements, and they had an imbalanced diet, which was considerably low in several essential nutrients and high in some food materials.

    This is an age-by-age summation of literature on over 100 sites (of more than 250 excavated prehistoric ruins on the Korean Peninsula: about 160 places in South Korea--Paleolithic Age 15, Neolithic Age 21, Bronze Age 90 and Iron Age 35--and about 90 places in North Korea) which produced dietary-habit-related devices such as hunting tools, fishing instruments, farming equipments, tools of daily life, and human bones and teeth. 1) Various dietary-habit-related Old Stone-Age tools, instruments and other items were found. Among them were stone axes, stone hand axes, fish spears and hooks made of bone or horn, stone blades, stone scrapers and stone drills believed to have been used in daily life, and charcoal and sites of furnaces used for cooking. Furthermore, it was found that there were severe dental abrasions and dental caries among the inhabitants of the Korean Peninsula in the Old Stone Age. 2) Some evidences were found which lead us to believe that hunting was practiced with stone arrowheads in the New Stone Age. Stone net sinkers, which is the evidence of the use of fish nets, were also found. In addition, farming stone tools and charred cereals, both of which date back to the latter part of this period, were unearthed. Millstones, which began to be used in this age, and livestock bones were found. Where these items were discovered, 23 maxillae and mandibles with teeth and a total of 231 separate teeth of Neolithic period human beings were reported. However, there are no records indicating dental caries, but some records describe severe abrasion.

    The non-specific immune parameters, disease resistance and immune genes expressions in Macrobrachium rosenbergii were evaluated at 120 days of post feeding the diets containing the extracts of banana, Musa acuminate, fruit's peel (banana peels extract, BPE) at 0, 1.0, 3.0 and 6.0 g kg(-1). Results showed that prawns fed with a diet containing BPE at the level of 1.0, 3.0 and 6.0 g kg(-1) for 120 days had a significantly higher survival rate (30.0%, 40.0% and 56.7%, respectively) than those fed with the control diet after challenge with Lactococcus garvieae for 144 h, and the respective relative survival percentages were 22.2%, 33.3%, and 51.9%, respectively. Dietary BPE supplementation at 3.0 and/or 6.0 g kg(-1) for 120 days showed a significant increase total haemocyte count (THC), granular cell (GC), superoxide dismutase (SOD) activity, phenoloxidase (PO) activity, transglutaminase (TG) activity, and phagocytic activity and clearance efficiency to L. garvieae infection, and meanwhile, the significant decrease in haemolymph clotting times and respiratory bursts (RBs) per haemocyte of prawns were revealed. Furthermore, the mRNA expressions of prophenoloxidase (proPO), lipopolysaccharide and β-1,3-glucan binding protein (LGBP), peroxinectin (PE), transglutaminase (TG), and crustin (CT) were significantly increased. We therefore recommend that BPE can be used as an immunomodulator for prawns through dietary administration at 6.0 g kg(-1) for a long term (over 120 days) to modify immune responses and genes expression following the enhanced resistance against pathogens.

    Full Text Available Aim: to study the association between the dietary habits and behavioural factors with the increased risk of obesity amongst adolescents in Dubai, United Arab Emirates (UAE. Method: A cross-sectional study was carried out among 661 adolescents (324 boys and 337 girls aged 12 to 17 years selected by means of a multistage stratified random sampling technique. Results: The highest percentage of obesity was observed at 14 years of age in boys (30.5% and at 13 years of age in girls (35.4%. There was a significant association between the frequency of eating breakfast (P =0.048, snacking between breakfast and lunch (P = 0.044, and obesity in girls but not in boys. A high risk of obesity was associated with eating breakfast at school in both boys (OR = 3.0; CI 1.1-8.3 and girls (OR = 3.4; CI 1.6-7.4. Fast foods showed a significant association with obesity in girls (P = 0.007, but not in boys (P = 0.745. The risk of obesity was higher in boys who ate fast foods at home (OR = 1.3; CI 0.5-3.2 but less in girls (OR = 0.2; CI 0.1-1.0. Conclusion: Intervention programs focused on promoting changes in lifestyles, food habits and increasing physical activity need to be implemented at the earliest.

    Breakfast skipping is prevalent among adolescents and young women, and deprives the body of important nutrients. This study was conducted to assess the correlation between breakfast eating and sociodemographic and lifestyle criteria. A cross-sectional study was carried out on a convenient sample of 400 female students selected from the female sector of King Abdulaziz University, Jeddah, Saudi Arabia. Home breakfast habit and other lifestyle characteristics were studied using a standardized questionnaire. Logistic regression was used to examine the relationship between home breakfast habit and different predictors. Home breakfast skippers constituted 71.75% of the whole sample. Breakfast eaters had a significantly higher BMI compared with breakfast skippers (22.66±4.88 vs. 21.58±4.09 in home breakfast skippers; P=0.025). Irrespective of other sociodemographic and lifestyle variables, fathers' education lower than university level negatively predicted home breakfast eating [Exp B=0.40, confidence interval (CI)=0.21-0.77], and being employed positively predicted breakfast eating (Exp B=2.31, CI=1.04-5.15). Likewise, consuming less amount of junk food and fewer soft drinks (Exp B=2.57, CI=1.54-4.28, and Exp B=2.59, CI=1.39-4.81, respectively) and consuming more milk and dairy products (Exp B=1.91, CI=1.16-3.15) correlated positively with home breakfast eating. Breakfast skipping was prevalent among adolescents and young women in the studied sample. Unhealthy dietary habits, father's education lower than university level, and father being unemployed positively predicted breakfast skipping of daughters at home. This implies that breakfast eating can be encouraged by approaching parents in addition to their daughters.

    Full Text Available Abstract Background Previous studies showed that cognitive ability is related to health and mortality. The cause of this relationship remains largely unknown. One plausible explanation is that cognitive ability is related to behaviours that affect health. This study investigates whether cognitive ability is related to healthy dietary habits, physical activity and appropriate bodyweight in adolescents and examines whether self-control mediates the relationship between cognitive ability and health behaviour. Methods In total 201 high-school students aged between 15 and 20 participated in the study. They completed three cognitive tests, measuring cognitive ability, reaction time and memory span, and completed a questionnaire on self-control, dietary habits, physical activity and bodyweight. Results Results show that adolescents scoring high on the cognitive ability test have healthier dietary habits and engage more often in physical activity. Adolescents with high self-control have a healthier eating pattern, are more often physically active and have lower BMI's. Both reaction time and memory span were not related to dietary habits and physical activity. Self-control was not related to cognitive ability and could not, therefore, mediate the relationship between cognitive ability and health in this study. Conclusion In conclusion, the link between cognitive ability and health behaviour could explain - in part - the relationship between cognitive ability and health. Self-control cannot explain this link.

    Aging is associated with morphological and functional changes in the brain, resulting in the deterioration of cognitive performance. Growth factors like BDNF are suggested to be involved in the regulation of age-related processes in the brain. A novel dietary supplement produced from purified nerve cell proteins, N-PEP-12, has shown to share properties with naturally occurring peptide growth factors by stimulating neurite outgrowth and beneficial effects on neuronal survival and protection against metabolic stress in cell cultures. The current study investigates the effects of long-term intake on age-dependent memory decline by assessing cognitive performance and synaptic density. All the experiments were performed in aged Long Evans rats randomly assigned to saline or N-PEP-12 once daily by gavage over a period of three months. Behavioral tests were performed in the Morris Water Maze after one, two and three months of treatment. Histological examinations were performed in the hippocampal formation and in the entorhinal cortex by measuring the synaptic density. This study shows that the oral intake of N-PEP-12 has beneficial effects on the cognitive performance of aged animals and that these effects go along with an increase in the synaptic density. Thus, N-PEP-12 may help maintain memory and learning performance during the aging process.

    2008-02-28

    In recent years, a notable number of studies have shown that some foodstuffs might be a potential source of exposure to chemical pollutants, some of them with a well-known toxicity in humans. Based on the importance of a healthy diet, we have designed the software RIBEFOOD, a new Internet resource that allows the quantitative determination of the human intake of a long series of micro- and macronutrients contained in widely consumed foodstuffs, and with an important nutritional value. RIBEFOOD is also able to determine the dietary intake of a number of chemical contaminants (i.e., metals, dioxins and furans, PCBs, polycyclic aromatic hydrocarbons, etc.). In this paper, we introduce RIBEFOOD, and how it may be used as an easy Internet tool in order to optimize the dietary habits of any subject by increasing the intake of beneficial nutrients and by reducing that of toxic pollutants. RIBEFOOD can be useful not only for professionals (general physicians, nutritionists, endocrinologists, toxicologists, etc.), but also for the general population. It is available at: http://www.fmcs.urv.cat/ribefood/.

    Full Text Available Background and Aims To document the nutritional content of food intake in overweight and obese people, in order to change dietary habits for acquiring the normal weight. Material and methods We assessed the nutritional content of food intake (kilocalories, vitamins and minerals in a sample of 124 overweight and obese people and 33 subjects with normal weight. We also measured abdominal circumference, percent of body fat and resting metabolic rate. Results Overweight and obese patients, compared to normal weight, have a significant increased intake of vitamin A (p=0.002, vitamin B1 (p=0.037, vitamin B5 (p=0.047, vitamin C (p=0.029 and vitamin D (p=0.015, sodium (p=0.036, iron (p=0.032 and selenium (p=0.007. The percent of body fat in obese persons is increased (p=0.00001 and very close to abnormal in patients with no weight problems. An increased food intake, above the calculated resting metabolic rate, is associated with a slower metabolism and a rapid resting metabolic rate is often associated with food intake below resting metabolic rate (p=0.002. Conclusions All subjects had imbalanced intake of vitamins and minerals. The normal weight group didn’t achieve the dietary recommendations for vitamins and minerals and we found that these subjects had risk factors for cardiac diseases like increased abdominal circumference, body fat and sodium intake.

    Compared measures of physical activity and dietary habits used in the Health Is Power (HIP) study, and described the associations of physical activity and dietary habits among African American and Hispanic or Latino women, adjusted for weight status. Cross-sectional baseline data were compared for community dwelling, healthy African American (N = 262) and Hispanic or Latina women (N = 148) who participated in HIP. Physical activity was measured using the International Physical Activity Questionnaire (IPAQ) long form, the Check And Line Questionnaire (CALQ) log and accelerometry. Dietary habits were measured using NCI 24-h recall screeners, vegetable and fruit (VF) logs and the NCI Diet History Questionnaire (DHQ). Differences in physical activity and dietary habits were assessed using simultaneous 2 (ethnicity) × 3 (weight status) ANCOVAs adjusted for age and socioeconomic status. Women (M age = 44.4 ± 10.9 years) were obese (M = 34.0 ± 9.7 kg/m2), did not meet physical activity guidelines as measured by accelerometry (M = 19.4 ± 19.1 min MVPA/day) and ate few VF (M = 2.8 ± 2.7 servings/day). DHQ variables differed by weight status. IPAQ was associated with CALQ, and CALQ with accelerometry (P < .05). IPAQ was not associated with accelerometry. Regardless of ethnicity, normal weight women did more physical activity, reported more VF consumption, and consumed more fat calories than overweight and obese women (Ps < .05). African American women did more MVPA than Hispanic or Latino women (P < .001). Relationships between behaviors and weight status suggest accelerometry and DHQ are preferable, regardless of ethnicity; and studies may capture different domains of physical activity and dietary habits depending on measure used.

    2014-03-01

    Full Text Available INTRODUCTION: Obesity has reached epidemic proportions globally and there is an alarming trend in the rise in childhood obesity. In the majority it is caused by an unhealthy diet and lack of exercise in children. With more fast-food restaurants appearing on every street corner it gives children an easy way to eat more unhealthy food. Children are also happier when they sit for hours in front of television or play on their play station. Studies show that in India, nearly 15 to 20% of children are overweight and 30% are in the risk of falling in this category. Although much importance has been given to under-nutrition in our country, obesity is slowly emerging as the future-killer. Hence this study is a small endeavour to know the knowledge and attitude of school children studying in government and private schools in Khammam regarding dietary habits. MATERIALS & METHODS: A cross-sectional study was carried out to study the Knowledge, attitude and dietary practices of secondary school students in Khammam town over a period of two months. List of schools was obtained from Secondary Education Board. Among the total available schools 128 (includes 38 Government, 90 Private schools, 12 schools were included in the study (6 schools from Government &6 schools from Private strata were selected conveniently. Pre tested, pre designed questionnaire was given to Students that included questions on their eating habits and physical activity and their body mass index (BMI was calculated using Quetelets index. Body mass index (BMI was used to assess students' weight status. Statistical analysis was performed using the Statistical Package for Social Sciences software (SPSS version 21.0. OBJECTIVES: To assess the prevalence of overweight and obesity in a randomly selected government and private urban schools in Khammam. To assess the Knowledge, attitude regarding dietary practices of secondary school students of Khammam town. RESULTS: Among total number of students

    Hepatic lipase (HL) plays a pivotal role in the metabolism of HDL and LDL. Recent genome-wide association studies have identified common variants in the HL gene (LIPC) associated with HDL cholesterol. We tested the effect of a common variant in LIPC on changes in blood lipids in response to weight-loss diets in the Preventing Overweight Using Novel Dietary Strategies Trial. We genotyped LIPC rs2070895 in 743 overweight or obese adults aged 30-70 y (61% women) who were assigned to high-fat (40% energy) or low-fat (20% energy) diets for 2 y. We measured serum concentrations of total cholesterol (TC), triglycerides, LDL cholesterol, and HDL cholesterol at baseline and 2 y of intervention. At 2 y of intervention, dietary fat modified effects of the variant on changes in serum TC, LDL cholesterol, and HDL cholesterol (P-interaction: 0.0008, 0.004, and 0.03, respectively). In the low-fat group, as compared to the G allele, the A allele tended to be related to the decrease in TC and LDL cholesterol concentrations [TC (β ± SE): -5.5 ± 3.0, P = 0.07; LDL cholesterol: -4.8 ± 2.5, P = 0.06] and a lower increase in HDL cholesterol concentrations (β ± SE: -1.37 ± 0.69, P = 0.048), whereas an opposite effect in the high-fat diet group was evident [TC (β ± SE): 7.3 ± 2.7, P = 0.008; LDL cholesterol: 4.1 ± 2.3, P = 0.07], and there was no genetic effect on changes in HDL cholesterol concentrations (P = 0.54). Dietary fat intake modifies the effect of a common variant in LIPC on changes in serum lipids during a long-term weight-loss intervention in overweight or obese adults.

    Assess longitudinal changes in dietary habits and attitudes of elderly Europeans in relation to selected socio-economic factors. Longitudinal survey with a baseline measurement in 1988/1989 and a follow-up measurement in 1993, using a standardized questionnaire. Elderly men and women born between 1913 and 1918. The second SENECA survey in 1993 assessed the dietary intake and the nutritional status of 676 men and 759 women aged 74-79 years in 13 small towns. In 9 of these towns, 571 men and 603 women had already been surveyed during the baseline study in 1988/1989. An increased regularity of food intake, as assessed by the consumption of daily cooked meals, was shown for this group of successfully aging elderly subjects. In three towns, Haguenau/F, Betanzos/E and Vila Franca de Xira/P, a disproportionate increase in subjects never shopping, not shopping daily and not consuming home-produced foods was observed. This suggests a higher than average loss in activity in these towns. Differences in food budget problems, in including or avoiding foods for health reasons or in following special diets could not be evaluated because of methodological problems. It had to be assumed that, for psychological reasons, subjects responded differently or interviewers questioned the subjects in different ways in the two surveys. In 1993, meal patterns were for the first time assessed quantitatively. Highly significant differences between northern (Culemborg/NL, Roskilde/DK, Ballymoney-Limavady-Portstewart/NI/UK) and more southern towns could be shown with regard to the structure of all three main daily meals and also to the distribution of energy intake during the day and to the time spent for meal preparation and eating. The possibility that differences in meal patterns might affect physiological functions requires the regular inclusion of this kind of data in all dietary surveys and the elaboration of the respective standardized methods.

    Food neophobia (FN) is described as the rejection to eat unknown foods. Because only little is known about the role of FN in adolescence the aim of this study was to examine potential determinants of FN and associations with dietary habits of DONALD study participants. FN was measured with Pliner's and Hobden's Food Neophobia Scale (FN Score (FNS): range 10-70) in 166 10-18-year-old adolescents. Participants' age, sex, body weight status and duration of breast-feeding as well as parents' FN and educational status were considered as determinants. Energy intake, distribution of macronutrients and two variety scores were calculated from 3-day weighed dietary records. Multivariable general linear models were performed for data analyses. Boys and girls did not differ in their FNS (median (Min-Max): boys 31 (10-58), girls 32 (14-59)). Increasing age (p = 0.010) and duration of total breast-feeding (p = 0.006) were associated with decreasing FNS in girls only. FN was further positively associated with parental FN in the total sample (p = 0.004). FN was negatively associated with protein intake in the total sample (p = 0.017). The overall low level of FN in the DONALD study can be ascribed to the low level of FN in adolescence in general. Congruently with other studies, age and breast-feeding duration were identified as determinants of girls' FN and parental FN was identified as determinant of FN in the total sample. Further, our results indicate that FN leads to reduced protein intakes. Dietary variety was not strongly affected, possibly because of a broad variety of food supply in Germany.

    The purpose of this study was to investigate the dietary taurine intake, nutrients intake, dietary habits and life stress by depression in Korean female college students. In this study, research data were collected in March 2009 and 65 patients with depression and 65 controls without depression participated. The CES-D (Center for Epidemiologic Studies Depression) scale was used for depression measure and controls were matched for age. A 3-day recall method was used for dietary assessment (2 weekdays and 1 weekend day). Average height, weight and body mass index (BMI) were 161.3+/-0.5 cm, 55.3+/-1.0 kg and 21.2+/-0.4 kg/m2 for depression patients and those of control group were 161.4+/-0.7 cm, 53.1+/-0.8 kg and 20.3+/-0.2 kg/m2, respectively. Average dietary taurine intakes of depression patients and control group were 89.1 and 88.0 mg/day, respectively. There was no significant difference in dietary taurine intake between depression patients and control group. The average intakes of vitamin A (pnutrition status. Also depression patients have higher life stress score.Therefore, continuous nutrition education and counselling for good dietary habits and balanced nutrition status are needed to prevent depression in Korean college students.

    Full Text Available Background Tracking of blood pressure from early life to adulthood and the increasing prevalence of elevated blood pressure in the pediatric age group are considered as important health issues. Rapid lifestyle change and dietary habits are considered as important determinants of this problem. This study aimed to systematically review the studies on the association of dietary habits and blood pressure in the pediatric age group.  Materials and Methods The search was conducted from November 2015 to August 2016 .Those papers were included that investigated the association of dietary habits on blood pressure in children and adolescents aged less than 18 years. The following medical subject headings and keywords were used to search all field (Diet OR nutrition OR nutrient OR food OR food habits OR food preferences AND (Blood pressure OR hypertension OR high blood pressure OR systolic pressure OR diastolic pressure OR Systolic Blood Pressure [TIAB] OR Diastolic Blood Pressure [TIAB] AND (child [Mesh] OR children [TIAB] OR adolescent [Mesh] [TIAB] OR pediatrics [Mesh] OR paediatric [TIAB] Results A total of 549 studies were initially identified in the databases. After excluding duplicate studies, 270 articles were retrieved and we reviewed them based on their titles and abstracts; then 161 articles were selected for more detail review. Findings of multiple studies showed the beneficial effect of fruits, vegetables and dairy products on blood pressure in children. Conclusion Increasing evidences indicate that dietary habits, notably daily salt intake of children is directly related to their blood pressure level. Our findings serve as confirmatory evidence on the necessity of paying more attention to primordial and primary prevention of hypertension.

    To determine the factors that are commonly associated with both the dietary habits of older adults living in the community and depressive symptoms in this group. Secondary analysis of data on Mexico City obtained by means of the multicenter study on Health, Well-being, and Aging (Salud, Bienestar y Envejecimiento, SABE) that was carried out in 1999 and 2000. The following variables were examined: presence or absence of depressive symptoms, according to Yesavage's Geriatric Depression Scale (GDS); mental status, as reflected by the score obtained on a modified, shortened version of Folstein's Mini-mental State Examination (MMSE); and functional capacity, as measured by Katz' Index of Independence in Activities of Daily Living. Those whose score on the shortened MMSE was 12 points or less were asked to respond to the Pfeffer Functional Activities Questionnaire, which was used to assess their ability to perform the basic activities of daily living. Information was obtained through self-report on the material, physical, psychological, and social aspects of purchasing, preparing, and consuming food products and of oral health status during the most recent 12-month period. Variables that were significantly associated with the results obtained on the GDS were included in a multivariate regression analysis; several statistical models were created, and variables that were shown to be statistically significant in the stepwise multivariate linear regression were used to determine the best-fitting explanatory model for the results obtained on the GDS. The average age of study participants was 64.4 +/- 8.6 years, and the prevalence of depressive symptoms was 66%. The score obtained on the GDS showed a significant association with the presence of arterial hypertension (P < 0.01), but not with the self-reported presence of diabetes, neoplasia, stroke, lung disease or heart disease. However, the use of dental prostheses (P < 0.01), urinary incontinence (P < 0.01), and falls (P < 0

    The purpose of this review is to provide a summary of studies on the effectiveness nutrition education interventions used by college students. Electronic databases such as Medline, Science Direct, CINAHL (EBSCOhost), and Google Scholar were explored for articles that involved nutrition education interventions for college students and that were published between 1990 and 2011. Fourteen studies, which involved a total of 1668 college students as respondents, were identified and met the inclusion criteria. The results showed that there were 3 major forms of nutrition education interventions: web-based education, lectures, and supplement provisions. Dietary intake measures were used in almost all studies and were primarily collected with food records, recall, food frequency questionnaires, and dietary habit questionnaires. The outcome measures varied among the studies, with indicators such as consumption of food, nutrition knowledge, dietary habits, physical activity, and quality of life. Methodological issues were also identified. In general, college students experienced significant changes in their dietary habits after the interventions were employed. The highlighted methodological issues should be considered to improve the quality of similar research in future.

    Patterns of nutritional behaviours shaped in childhood and during the period of adolescents are mostly continued in adult life, and on these patterns, to a great degree, depends the risk of development of many chronic diseases. The aim of this study was to assess the relationship between dietary habits and body image perception among Polish adolescents and young adults. The study group covered 14,511 adolescents/young adults: 10,081 children attending high schools and secondary schools, and 4,428 university students. More than 87% of schoolchildren and students admitted that that they snacked between meals everyday, and 1/3 of them mentioned that they consumed meals at night. As many as 41.40% of schoolchildren, and 46.70% of students experienced the feeling of overeating at least several times a week. Analysis of the respondents BMI showed that in the group of students there were considerably more respondents obese or overweight, compared to the group of schoolchildren. Fear of gaining weight was mentioned by 9.90% of respondents, including 6.90% of those with normal body structure, 1.40% with underweight or overweight, and 0.40% of those obese. As many as 54.60% of the total number of respondents described their body structure as remaining within the normal, 23.7% - as slim, 13.9% reported that they were overweight, 6% - thin, while 1.7% considered themselves as obese. A comprehensive analysis of the data available, including attempts at dieting or gaining weight, indicated that approximately ¾ of obese respondents had undertaken attempts in the past to reduce their body weight. The importance of physical activity and healthy eating habits should be given due attention not only to prevent obesity but also other eating disorder.

    Weight loss surgery (WLS) is efficacious for long-term weight reduction and decreases overall mortality in severely obese patients. The mechanisms implicated in long-term weight loss are not fully understood. Proposed mechanisms include changes in gut hormones and brain regulation of appetite and satiety. We aimed to investigate the long-term ghrelin and leptin profiles and changes in food preference and eating behavior after WLS in adolescent patients. Two obese females aged 15 years and 14 4/12 years, who did not respond to lifestyle changes, including dietary intervention and physical exercise in combination with medical therapy, underwent robotic-assisted gastroplication. Anthropometric measurements, food habits and eating behavior, as well as metabolic and hormonal changes during long-term post-surgical follow-up were monitored. Long-term weight reduction was obtained in both patients, with a significant decrease in waist circumference. Resting energy expenditure showed a decrease over time, with a respiratory quotient that increased showing a shift from oxidation of a high-fat diet before surgery to oxidation of a mixed diet two and three years later. Both subjects improved their eating habits and lifestyle. Co-morbidity resolution was also noted. Increased pre-prandial ghrelin levels as well as higher post-prandial ghrelin and a leptin drop compared with pre-surgery values were observed in both patients. Persistent weight loss after gastroplication is associated with a favorable change in gut hormones and food preferences. The role of hormonal and sensory components in long-term results seems crucial. Particularly in adolescent patients, a multidisciplinary approach and continuous nutritional care is mandatory for weight maintenance and consolidation of changes.

    Full Text Available Objective: Nutritional status directly affects the growing up of children in terms of physical and mental development. In the urban slums the underprivileged children lag behind the basic necessary amount of food and nutrition which is likely to lead to their ill development. This study was undertaken to investigate the dietary food intake pattern among urban slum dwelling children attending schools Dhaka city and to examine the association with various social factors.Material & Methods: This study is a cross-sectional study among 396 school going children who are residents of slums in different parts of Dhaka Metropolitan city.Findings: The age of the children were categorized into three age groups; Mean age for the children of age group-1 was 6.51 (±1.01 years, for the age group-2 was 9.24 (±1.09 years and for the age group-3 was 12.5 (±0.91 years. In 77.8 % of the cases the child gets three meals per day but inadequate in amount. In most of the cases the common foods were rice, lentil, potato and green leafy vegetables. The food frequencies reported by the children were; eggs: 1.4 times per week, milk: 1.2 times per week, meat: 0.4 times per week, fish: 2.8 times per week and fruits 2.9 times per week. Those children from families with lower incomes and less educated parents had a dietary pattern which tended to be poor regarding egg, milk, meat and fruit.Conclusion: The diets of these urban slum school children were inadequate for macronutrients and micronutrient, which is a danger for significant nutritional and health implications. The need to develop healthy food supply and habits should be emphasized.

    Changing eating habits, population growth and movements, global trade of foodstuff, changes in food production systems, climate change, increased awareness and better diagnostic tools are some of the main drivers affecting the emergence or re-emergence of many foodborne parasitic diseases in recent years. In particular, the increasing demand for exotic and raw food is one of the reasons why reports of foodborne infections, and especially waterborne parasitosis, have increased in the last years. Moreover increasing global demand for protein of animal origin has led to certain farming practices (e.g. aquaculture) increasing in emerging or developing countries, where health monitoring may not be sufficiently implemented. Therefore, high quality epidemiological data are needed which together with biological, economic, social and cultural variables should be taken into account when setting control programs for these increasingly popular production systems in emerging economies. This review focuses on the dietary, social, economic and environmental changes that may cause an increase in human exposure to foodborne parasites. Some examples illustrating these new epidemiological dynamics of transmission foodborne parasitic disease are presented.

    Full Text Available Several recent studies have described a strong correlation between nutritional or economic data and the number of Nobel awards obtained across a large range of countries. This sheds new light on the intriguing question of the key predictors of Nobel awards chances. However, all these studies have been focused on a single predictor and were only based on simple correlation and/or linear model analysis. The main aim of the present study was thus to clarify this debate by simultaneously exploring the influence of food consumption (cacao, milk, and wine, economic variables (gross domestic product and scientific activity (number of publications and research expenditure on Nobel awards. An innovative statistical analysis, hierarchical partitioning, has been used because it enables us to reduce collinearity problems by determining and comparing the independent contribution of each factor. Our results clearly indicate that a country's number of Nobel awards can be mainly predicted by its scientific achievements such as number of publications and research expenditure. Conversely, dietary habits and the global economy variable are only minor predictors; this finding contradicts the conclusions of previous studies. Dedicating a large proportion of the GDP to research and to the publication of a high number of scientific papers would thus create fertile ground for obtaining Nobel awards.

    This study describes the correlation of traditional perceptions and dietary habits with the incidence of neurolathyrism to propose preventive measures. Therefore, 118 households of South Wollo and North Gondar (Amhara Regional State, Ethiopia), of which one third had at least one neurolathyrism affected member, were interviewed. Most of the affected families in this study had one neurolathyrism victim, being predominantly male and of younger age. The incidence among youngsters (boys and girls) was significantly correlated with the consumption of green unripe seeds (eshet), confirming this as a risk factor for developing neurolathyrism. The consumption of other popular grass pea preparations was not age related. Neurolathyrism patients did not attempt any medication as most people knew that neurolathyrism is incurable, but the consumption of grass pea was abandoned after developing the disease. The minority 'Woito' tribe was virtually unaffected. They were the only people reporting to consume fish which is rich in amino acids such as methionine and using metallic kitchen utensils in addition to clay pots. This observation points to the correlation between low neurolathyrism incidence and a better balanced diet as well as metallic kitchen utensils, suggesting a new approach for neurolathyrism prevention.

    2014-12-01

    Full Text Available The golden jackal is a medium-sized predator and omnivore, with a range covering the southern parts of the Palearctic, South Asia and northeastern Africa. The entire jackal population is now confined to a few clusters grouped into 7 sub-areas with criteria such as connectivity and isolation. Causes of decline seem to be related to the limited habitat availability due to changes in human agro-pastoral activities, which resulted mainly in reduced day-cover availability and possibly reduced food base. This review summarizes the basic aspects of golden jackal distribution, ecology and dietary habits, analyses the main threats and problems of jackal management. The jackals seem to do well in moderately modified agro-systems with non- invasive human activities. Barriers for jackal expansion and population recovery seems to be the mountains with extensive high forests or unbroken scrub, heavy snowy winters and irregular food supply, large intensively cultivated areas without cover, urbanization and established wolf populations. Agro pastoral changes during the past 25-30 years has resulted in habitat and human use changes, which have largely contributed to the massive jackal population declines. Following a short introduction on phylogeny, classification, and evolutionary ecology of the Canidae, this review provides the latest information on the distribution, biology and conservation status of Canid aureus species, organized by geographical region.

    The burden of diseases associated with unhealthy lifestyle behaviours continues to increase in the low- and middle-income countries including South Africa. Among the affected population are the health professionals who are assumed to be knowledgeable about healthy eating. This study aimed to determine the dietary habits of health professionals in a public district hospital in KwaZulu-Natal, South Africa. A cross-sectional survey was conducted in 2012 among 109 randomly selected health professionals. Each received a questionnaire consisting of mostly closed and few open-ended questions. Its main focus was the dietary and eating habits of the professionals. An ethical clearance was granted by the Medunsa Research and Ethics committee at the University of Limpopo. Permission to conduct the study was sought and obtained from participants as well. Descriptive statistics and frequencies were used to analyse data. A 100% (109) response rate was achieved. The majority skipped meals especially breakfast with a significant positive correlation between breakfast intake per week and age (r = 0.98, p = 0.048). The majority consumed a lot of unhealthy foods and carbonated beverages with sugar. Consumption of fruits, vegetables, high fibre and whole grain foods was less common. The study showed poor eating habits among participants. Urgent health interventions are therefore indicated to highlight the importance of healthy eating habits among the entire population.

    The home food environment influences children's eating behaviors and potentially affects overall diet quality. The aim of the present study was to evaluate the relationship between the home food environment and Hispanic children's diet quality. Hispanic children, 10-14 years of age (n=187), and their parents participated in this cross-sectional study. The Healthy Eating Index (HEI) was used to determine diet quality based on reported dietary intake obtained through a food frequency questionnaire administered to the children. Parents self-reported home food availability, familial eating habits, and their own habitual diet through a home environment survey. The children's HEI total score was 59.4±8.8. Reported diets did not adhere to the dietary recommendations for total vegetables, greens and beans, whole grains, seafood and plant proteins, fatty acids, refined grains, sodium, solid fats, and added sugars. None of the participants had "good" scores (HEI, >80), 86% had scores that "need improvement" (HEI, 51-80), and 14% had "poor" scores (HEI, food availability, parental diet, and familial eating habits seem to play an important role in the diet quality of children. Interventions targeting family education on healthful dietary habits at home could have a positive impact on children's diet quality and overall health.

    Full Text Available Dental caries is a major cause of tooth loss in children and young adults. Dental caries have been linked to the situation of underprivileged families, nutritional imbalance, and poor oral hygiene techniques, including lack of tooth brushing or flossing the teeth, and also have a genetic etiology. Dietary habits and dental hygiene practice can result in high caries in school children. This research aimed to reveal the correlation between dietary habits and dental hygiene practice with dental caries among school children in urban area of Semarang. The subjects of this research are the elementary student 7 – 9 years old enrolled in schools located in at urban area in Semarang in 2016 and the mother of a student who became the study sample. Data were statisically analyzed usingbivariate analysis and multivariate analysis. Based on the research result, it can be concluded that: there was no correlation between total carbohydrate intake, refined carbohydrate intake, fiber intake, dental hygiene practice with dental caries, bottle feeding and duration of bottle feeding were assosiated with dental cariest-score. Overall, def-t score in the study was very bad with high median of dental caries score and many children have dental caries t-score more than 6.How to CiteAli, O. I. M., Muis, F. & O, Oedijani.

  9. Analysing long term discursive processes

    DEFF Research Database (Denmark)

    Horsbøl, Anders

    What do timescales - the notion that processes take place or can be viewed within a shorter or longer temporal range (Lemke 2005) - mean for the analysis of discourse? What are the methodological consequences of analyzing discourse at different timescales? It may be argued that discourse analysis...... in general has favored either the analysis of short term processes such as interviews, discussions, and lessons, or the analysis of non-processual entities such as (multimodal) texts, arguments, discursive repertoires, and discourses (in a Foucaultian sense). In contrast, analysis of long term processes...... which extend beyond the single interaction, for instance negotiations or planning processes, seems to have played a less important role, with studies such as Iedema 2001 and Wodak 2000 as exceptions. These long term processes, however, are central to the constitution and workings of organizations...

    Poor eating habits among young adults are a public health concern. This survey examined the eating habits of undergraduate university students in Finland. We assessed students' dietary intake of a variety of food groups, their adherence to international dietary guidelines (whole sample and by gender), and the associations between importance of eating healthy and dietary guidelines adherence (whole sample and by gender). During the 2013-2014 academic year, 1,189 undergraduate students enrolled at the University of Turku in southwestern Finland completed an online self-administered questionnaire. Students reported their eating habits of 12 food groups, the number of daily servings of fruits/vegetables they consume and how important it is for them to eat healthy. For dietary adherence recommendations, we employed WHO guidelines. Chi-square statistic tested the differences in dietary guidelines adherence between males and females and also the associations between the gradients of importance of healthy eating and the self reported eating habits for each of the food groups, for the whole sample and by gender. We observed high levels of dietary adherence (>70%) for most of the 'unhealthy food' items (cake/cookies, snacks, fast food/canned food, and lemonade/soft drinks), and moderate adherence for most of the 'healthy food' items (>50%) (dairy/dairy products, fruit/vegetables servings/day, fresh fruit, salads/raw vegetables and cereal/cereal products). Fish/seafood, meat/sausage products and cooked vegetables had levels sausage products, fast food/canned food and for most 'healthy food' items (p≤0.001), whereas men had better adherence for sweets (difference=12.8%, p≤0.001), lemonade/soft drinks (difference=16.7%, p≤0.001) and fish/seafood (difference=6.6%, p=0.040) compared to women. Most students considered important to eat healthy (78.8%). The importance of eating healthy was significantly associated with adherence for all food groups besides sweets and cake

    This study was performed in order to analyze the relationships between hair zinc, lead, and cadmium with the kind of diet consumed (by recall of the diet consumed the previous 14 days), living area (urban or rural), tobacco smoking, and body mass index (BMI) among 419 individuals of the Canary Archipelago. Median values and interquartile range were 43 μg/g (18.50-132.50) for zinc, 4.09 μg/g (2.19-8.38) for lead, and 0.128 μg/g (0.05-0.30) for cadmium. We observed that hair zinc was markedly elevated among those consuming fish more frequently and, to a lesser amount, among those who consumed meat frequently, among those living in urban areas, and among those with BMI over 25 kg/m(2), keeping a significant relationship with BMI. Hair lead was also higher among fish consumers, showed a trend to higher values among inhabitants of urban areas, and was lower among obese individuals. Hair cadmium was higher among those who consumed less vegetables and fruits. By multivariate analysis, introducing the variables meat, fish, and vegetable consumption, urban/rural; sex; age; and BMI values, we observed that fish consumption (beta = 0.15) was the only variable independently associated to higher zinc levels; fish consumption (beta = 0.15) and meat consumption (beta = 0.17) were related to high cadmium levels, whereas meat consumption was significantly associated to higher hair lead levels (beta = 0.15). Therefore, we conclude that hair zinc, cadmium, and lead seem to depend more heavily on dietary habits than on tobacco consumption or living in rural or urban areas.

    Full Text Available Background: Social inequalities in health are a major and even growing problem in all European countries. Objective: The aim of the present study was to describe 1 differences in dietary habits among Norwegian adolescents by gender and socioeconomic status; 2 differences in self-reported knowledge of dietary guidelines among their parents according to socioeconomic status. Design: In 2012, a cross-sectional study where students filled in a web-based food frequency questionnaire at school was conducted in nine lower secondary schools in Vest-Agder County, Norway. Socioeconomic status (SES and knowledge of dietary guidelines were obtained from the parents using a web-based questionnaire. In total, 517 ninth-grade students (mean age 13.9 out of 742 invited students participated in the study, giving a participation rate of 69.7%. The total number of dyads with information on both parents and students was 308 (41.5%. Results: The findings indicate that there is a tendency for girls to have a healthier diet than boys, with greater intake of fruits and vegetables (girls intake in median 3.5 units per day and boys 2.9 units per day, and lower intake of soft drinks (girls 0.25 l in median versus boys 0.5 l per week. Students from families with higher SES reported a significant higher intake of vegetables and fish, and lower intake of soft drinks and fast food than those from lower SES. Parents with higher SES reported a significantly better knowledge of dietary guidelines compared to those with lower SES. Conclusions: Differences in dietary habits were found between groups of students by gender and SES. Differences were also found in parents’ self-reported knowledge of dietary guidelines. This social patterning should be recognized in public health interventions.

    We investigated the relationship between cardiovascular disease (CVD) and the achieved blood pressure, dietary habits and the presence/absence of metabolic syndrome (MetS) in hypertensive patients treated with olmesartan medoxomil. A prospective cohort study with a 3-year follow-up was conducted in 14 721 olmesartan-naive outpatients (mean age: 64.9 years, 49.6% women) with essential hypertension. The association of CVD with achieved blood pressure, dietary habits and MetS was investigated by Cox proportional hazards analysis. There were 3059 patients (31.8%) with MetS (Japanese criteria) among 9625 evaluable patients. The mean baseline blood pressure was 157.4/88.8 mm Hg, which decreased to 134.0/76.1 mm Hg during treatment (Pdietary habits revealed a significant association between salt intake and the risk of stroke. Higher salt intake was associated with a significantly higher risk of stroke than lower salt intake (hazard ratio, 1.897; 95% confidence interval, 1.003-3.590). Blood pressure was well controlled in both patients with and without MetS, and there was no significant difference in the incidence of events between the two groups. In conclusion, the severity of hypertension (achieved blood pressure) is associated with the incidence of CVD, and the results of this study suggest that tight blood pressure control and salt restriction are important for preventing stroke.

    Childhood obesity is a multifactorial disease, in which unhealthy dietary patterns and sedentary lifestyles play a decisive role. The aim of this study was to assess the weight status, dietary habits and physical activity in Castile-La Mancha children. A cross-sectional study was conducted on 3061 children 6-12 years-old who were participating in the programme, "Alimenta su salud". Anthropometric measurements, food consumption frequency, dietary habits and physical activity were assessed by a questionnaire, including gender, age and geographical influences. The prevalence of subjects with excess weight-for-height was 24.0% and obesity was 14.3%, with geographical differences. Girls more often have mid-morning snacks, consume more supplements, and reported to be less active than boys. Special diets and sports activities were lower in children aged 6-9 years as compared to the 10-12 years old group. The intake of vegetables and fruit is low, while there is overconsumption of sausages, pastries, salted snacks, sweets and fast food, with some differences by age group. One out of four children is overweight or obese in this population. Children do not meet recommendations for fruit and vegetables and there is a high consumption of foods associated with obesity risk. Physical inactivity was more prevalent during the weekends, and among girls. Copyright © 2010 Asociación Española de Pediatría. Published by Elsevier Espana. All rights reserved.

    Full Text Available Introduction: In developing countries research in nutrition has primarily be focusing on preschool children and women of reproductive age.1,2 A large, multicountry study on the anthropometric status of rural school children in Ghana, Tanzania, Indonesia, Vietnam, and India found a high prevalence of stunting and underweight, ranging from 48% to 56% for stunting and from 34% to 62% for underweight.1 Anemia is estimated to affect 46% of 5- to 12-year-old children in low-income countries, with the highest prevalence in South Asia (50%.2 Because school-age children undergo a period of rapid growth, nutrient deficiencies at this age can lead to retarded growth3, anemia2, reduced immune function4 and impaired motor and cognitive development5, all of which may adversely affect academic performance through reduced learning capacity and poor school attendance6. Nutritional deficiency in children of school going age result from increased micronutrient needs for growth, as well as changes in eating and lifestyle habits arising from increasing independence from the family. During this time, nutritional requirements are high, yet vitamin and mineral intakes tend to be reduced as there is a greater consumption of ‘empty calories’, frequent meal skipping, adoption of inappropriate weight control behavior and decreased vegetable and fruit intake.7,8,9 In spite of the fact that in many countries much is known about the nutritional situation of children and adolescents10-16, less information is available for this age group than for adults, and no data exist on risk factors associated with inadequate intakes in the younger cohort. The quantity and quality of available information is scarce. There is mutual synergistic interrelationship between infections and nutritional status. Poor nutritional status increases the likelihood of acquiring an infectious disease and increased severity of infectious episode whereas infectious disease leads to worsening of

    Sedentary behaviour has been associated with obesity and related chronic diseases. Disentangling the nature of this association is complicated due to interactions with other lifestyle factors, such as dietary habits, yet limited research has investigated the relation between domain-specific sedentary behaviours and dietary habits in adults. The aim of this paper was to examine the association between domain-specific sedentary behaviours and dietary habits in adults and to test the moderating effect of age and gender on this association. A total of 6,037 participants from five urban regions in Europe completed an online survey, of which 6,001 were included in the analyses. Multilevel mixed-effects logistic regression analyses were used to examine main associations and interaction effects. All domain-specific sedentary behaviours, except transport-related sitting time, were significantly related to dietary habits. In general, having a higher sitting time was related to having less healthy dietary habits, especially for television viewing. Gender did not moderate any of the relations, and age was only a significant moderator in the relation between other leisure sitting time and alcohol consumption. Domain-specific sitting behaviours were related to unhealthy dietary behaviours. However, the small effect sizes suggest that individual level behavioural interventions focusing on sedentary behaviour will not be sufficient to improve dietary habits. The fact that almost none of the associations were moderated by age or gender suggests that these associations, and possibly also the effects of interventions targeting both behaviours, may hold across age and gender groups.

    The aim of this study was to investigate the prevalence of obesity, dietary habits, and sedentary patterns among Sudanese adolescents. A multistage stratified sampling method was used to select 945 adolescents (507 males and 438 females) aged 14 to 18 years, from Khartoum State, Sudan. A self-reported pretested questionnaire was used to collect the data. Overweight and obesity were determined using the International Obesity Task Force standard, which is based on body mass index for sex and age. Overweight and obesity were growing problems among urban Sudanese adolescents (10.7%). Breakfast was commonly consumed on a daily basis by the majority of adolescents (74.2%), followed by lunch (63.9%) and supper (33.5%). Snacking was not a common practice among these individuals. Vegetables (63.9%) were more frequently consumed (more than 3 days per week) than fruit (30.1%). There were significant differences between genders regarding intake of vegetables (P risk factors for diet-related chronic diseases such as unhealthy dietary habits and sedentary behaviors are starting to rise among urban adolescents in Sudan. This creates the need for immediate action to prevent and control these risk factors before these diseases become major public health problems. © The Author(s) 2016.

    Aminotransferase activity is a surrogate marker of liver injury showing strong correlations with obesity and metabolic syndrome. However, elevated aminotransferase activity is not uncommon in non-obese and non-alcoholic patients in clinical practice. To examine the relationship between sarcopenia and aminotransferase activity in a large population-based cohort. Data from the Korean National Health and Nutrition Examinations were used. A total of 13,431 subjects were included. A whole-body dual X-ray absorptiometry scan was performed on each patient to measure total and regional muscle mass. Appendicular skeletal muscle mass indices were also obtained. The prevalence of sarcopenia was significantly higher in the group with elevated aminotransferase levels than in the normal liver enzyme group (males: 26.5% vs. 16.9%; females: 38.3% vs. 22.1%, pfasting glucose and cholesterol levels. The frequency of elevated aminotransferase increased in male patients with sarcopenia after adjusting for potential confounding factors including age, body mass index, fasting glucose level, dietary, and exercise habits. However, the correlation was no longer observed in women after adjusting for body mass index. Sarcopenia is a risk factor for elevated aminotransferase in men, independently of body mass index, dietary habits, and physical activity. Copyright © 2015 Editrice Gastroenterologica Italiana S.r.l.

    Full Text Available An exploratory study was conducted to examine the effectiveness of a group gratitude intervention with 29 permanent residents at a long term care/skilled nursing facility in improving elder mood, behavior and well- being over a 3 week time period. The sample included individuals diagnosed with dementia, other cognitive impairment, major depressive disorder, insomnia and generalized anxiety disorder. The gratitude intervention consisted of asking elders to share what they are thankful for at the dinner table each day. Measures included the Elder Well Being Scale and The Dinner Rating Scale. On both measures, higher scores indicated better functioning. To test the hypothesis that post treatment elder well-being will be significantly higher than pretreatment elder well-being ratings, a one-way ANOVA was conducted. Post-hoc tests revealed a statistically significant increase in Elder Well Being Scale scores. An ANOVA of comparing Dinner Ratings demonstrated a nonsignificant increase over the 3 week experiment. Implications are discussed.

    The effects of an individualised nutritional education and support programme on dietary habits, nutritional knowledge, and nutritional status of 71 older adults living alone were examined. Although a regular dietary meal plan is recommended for improving nutritional status of older adults living alone, little research is done in this field in Korea. A pre- and post-test controlled quasi-experimental design was used at public health centres. The intervention group participated in an intensive nutritional education and support programme once a week for 8 weeks with dietary menus provided by home visiting nurses/dieticians; control group received usual care. Dietary habits and nutritional knowledge were assessed using structured questionnaires; nutritional intake status was analysed using Computer Aided Nutritional Analysis Program 5.0. The mean age of participants was 77.6 years, and 81.7% of the participants were women. At 8 weeks, there were significant interactions of group by time for dietary habits, nutritional knowledge, and selected nutritional status of protein, iron, and vitamins of B2 and C. Changes over time in the mean score of dietary habits and nutritional knowledge were significantly improved in the intervention group compared to the control group. The percentages of normal nutrition intake of protein, iron, and vitamins A and C in the intervention group were significantly higher than the control group at 8 weeks. Nutritional education and support programme positively impacted dietary habits, nutritional knowledge, and selected nutritional status in older adults living alone, and we highlight the need for community-based nutritional education and counselling programmes. Older adults living alone in a community have relatively poor nutritional status and thus require tailored nutritional intervention according to objective nutritional analysis. It is necessary to link visiting nurses with dieticians in the community to manage effective nutritional

    Full Text Available Abstract Background African Americans (AA suffer from an increased incidence and mortality of colorectal cancer (CRC. Environmental exposures including dietary habits likely contribute to a high burden of CRC, however, data on the dietary habits of AA is sparse. Diet might change the composition and the activities of the intestinal microbiota, in turn affecting fecal genotoxicity/mutagenicity that is thought to be associated with carcinogenesis. Methods We assessed dietary habits by food frequency questionnaire and by food records in 52 AA and 46 CA residents of the Eastern Shore of MD. Fecal microbiota composition was determined using 16S rRNA based methods and fecal genotoxicity measured using the Comet assay. Results AA reported an increased intake of heterocyclic amines and a decreased dietary intake of vitamins including vitamin D (p Conclusion Dietary habits of African Americans, including increased HCA intake and decreased vitamin D intake might at least partially contribute to CRC through modifications of gut microbiota composition that result in changes of the intestinal milieu.

    Food behaviour is acquired in childhood and is very defficult to be changed latterly in adulthood. The aim of this study was to evaluate if food behaviour and other health habits were in accordance with the nutrition knowledge of a sample of University students from different Health Sciences Careers. We studied 105 students (aged 21 +/- 2 years) from San Pablo-CEU University (Madrid); 21 where studying Nursing (N), 32 Pharmacy (Ph); 34 Nutrition and dietetics (ND) and 18 were students of Podology (P), all of them had been studying Nutrition as subject during 2003-2004 academic year. All the students filled a questionnaire about health habits and some body image perceptions, diet was evaluated by a 3 day diet record and nutrition knowledge by a 20 questions test. Height and weight were measured using standard procedures. ND students believed they had a medium-high level of nutrition knowledge while Pharmacy and nursing students believed they had a medium-low level and the podology ones had the perception to have a low level of knowledge in the subject. Results of test were in accordance with those perceptions as highest records were obtained by the Nutrition students. Nevertheless very few differences were found in the diet of the four populations. Mean energy intake was similar in the four groups, deficiencies (alcohol and physical activity) in the four populations. Even if N students believed and showed to have a better nutrition knowledge, no changes in food behaviour or other health habits were found. Improving knowledge does not necessary imply change in food habits.

    The aim of this study was to investigate whether body mass index (BMI), eating habits and sedentary behaviours were associated with sleep duration among Kuwaiti adolescents. The study is part of the Arab Teens Lifestyle Study (ATLS), which is a school-based cross-sectional multi-center collaborative study. A sample of 906 adolescents (boys and girls) aged 14-19 years was randomly selected from 6 Kuwaiti Governances using a multistage stratified cluster sampling technique. The findings revealed that the prevalence of overweight and obesity was 50.5% in boys and 46.5% in girls. The majority of boys (76%) and of girls (74%) fell into the short sleep duration category (6 hours/day or less). Sleep duration were found to be negatively associated with BMI (girls only). Watching television (boys and girls) and working on computers (boys only) were also negatively associated with sleep duration. While the consumption of breakfast (both genders) and milk (boys only) was positively associated with sleep duration (psleep duration (psleep duration which was associated with obesity measure, a combination of poor eating habits and more sedentary behaviors. The findings also suggest gender differences in these associations. Therefore, adequate sleep is an important modifiable risk factor to prevent obesity and was positively associated with some unhealthy lifestyle habits.

    Religion has been shown to be salutary on health, and a possible link between religion and positive health outcomes is diet. Research has shown that religiosity is associated with better diet but most studies were conducted in a multi-denominational context, which might be confounded with theological differences. This study examined the relationship between religiosity and diet within a homogenous group of believers. Data from survey of 574 Seventh-Day Adventists residing in West Malaysia, aged 18-80, were analyzed using multiple regressions. While none of the religious variables were significantly associated with fruit and vegetable intake, a higher level of religiosity was associated with a better dietary habit and vegetarian status. The mixed relationship between religiosity and diet suggest that further research is needed to explore how religion might influence the diet of adherents.

Serum H. pylori-specific IgG antibodies, total cholesterol (TC, triglycerides (TG, high-density lipoprotein-cholesterol (HDL-C, low-density lipoprotein-cholesterol (LDL-C, and fasting blood sugar (FBS levels were measured after an overnight fast. Results: The seroprevalence of H. pylori infection was 45.7%. H. pylori-positive subjects had lower mean levels of TC and TG and higher levels of HDL-C compared to H. pylori-negative subjects. In addition, lower levels of LDL-C (P = 0.044 and FBS (P = 0.05 were observed among subjects with positive H pylori infection. Only rare consumption of raw vegetables (odds ratio [OR] =3.74, 95% confidence interval [CI] =1.37–5.24 as well as higher levels of FBS (OR = 1.031, 95% CI = 1.001–1.99 were significantly associated with higher odds of H. pylori infection in both the univariate and multiple logistic regression analysis. Conclusion: In a small population of young students in southeastern of Iran, H. pylori infection was associated with low consumption of raw vegetables and higher serum blood glucose.

    The abrupt rise of colorectal cancer in developing countries is raising concern in healthcare settings. Studies on assessing relationships with modifiable and non-modifiable risk factors in the Pakistani population have been limited. The present investigation was designed to examine associations of dietary practices, addictive behavior and bowel habits in developing colorectal cancer (CRC) among patients in a low-resource setup. An age-gender matched case control study was conducted from October 2011 to July 2015 in Karachi, Pakistan. Cases were from the surgical oncology department of a public sector tertiary care hospital, while their two pair-matched controls were recruited from the general population. A structured questionnaire was used which included questions related to demographic characteristics, family history, dietary patterns, addictive behavior and bowel habits. A family history of cancer was associated with a 2.2 fold higher chance of developing CRC. Weight loss reduced the likelihood 7.6 times. Refraining from a high fat diet and consuming more vegetables showed protective effects for CRC. The risk of CRC was more than twice among smokers and those who consumed Asian specific addictive products as compared to those who avoid using these addictions (ORsmoking: 2.12, 95% CI: 1.08 - 4.17, ORpan: 2.92, 95% CI: 1.6 - 5.33, ORgutka: 2.13, 95% CI: 1.14 - 3.97). Use of NSAID attenuated risk of CRC up to 86% (OR: 0.14, 95% CI: 0.07 - 0.31). Most of the findings showed concordance with the literature elucidating protective effects of consuming vegetables and low fat diet while documenting adverse associations with family history, weight loss, constipation and hematochezia. Moreover, this study highlighted Asian specific indigenous addictive products as important factors. Further studies are needed to validate the findings produced by this research.

    Full Text Available The need to promote knowledge of health entails, in part, by encouraging healthy eating habits. The creation of popular science materials, especially at schools, by promoting guidance for the eating habits is presented as an important tool. Foods that contain bioactive compounds are called nutraceutical foods and about 35% of various cancers occur due to inadequate diets. Conventional therapies are used in the treatment of cancer, even though they are efficient in fighting tumors, to cause many harmful effects to the patient, and therefore the researches for alternative therapies have increased. Especially those act strengthening the immunologic system. The mushrooms are able to modulate carcinogenesis in all stages of the disease through different mechanisms of action of the bioactive compounds, thus having an antitumor effect that is assigned to restore and improve the immune response through stimulation of cellular immunity which are present polysaccharides the composition of the mushrooms, such as beta-glucans that besides the anticancer effect, it still has activity as immunostimulant, antioxidant, anti-inflammatory, which are already used in Japan as drugs for treating cancer patients. The aim of this work was to use learning as a tool for acquiring habits and eating behaviors in the general community and ownership and acquisition of knowledge about the antitumor potential of bioactive compounds in foods which are applied in cancer prevention through the scientific dissemination / education. Because it is a popular science work using written material and the dissemination of the material make for yourself the methodology used for the dissemination of scientific knowledge. Thus, the inclusion of consumption of mushrooms in the diet may represent an important step in the cancer prevention as the best form of prevention, and therefore it shows the need for available information to everyone, as it has proposed this work, disclosure.

    The research was conducted into 360 students of Medical University in Bialystok with differentiated nutritional status. The study involved 251 female students (46 with underweight, 186 with normal weight, 19 with excessive body weight) and 69 male students (7 with underweight, 47 with normal weight, 15 with excessive body weight). The quantity analyze of daily food rations was conducted on the base of the previous day 24 h dietary recall method. The computer program Diet 2.0 designed in the Institute of Food and Nutrition in Warsaw was used for calculations. Energetic value and basic nutrients supply was estimated and also the average content of dietary fiber and cholesterol. The results of the conducted research indicate lack ofbalanced content ofessential nutrients in daily food rations of the tested students of both sexes, irrespective of nutritional status. Energy supply was far too low comparing to recommended standards. It was proved that carbohydrate and fat supply was definitely lower than recommended standards. The research also showed low consumption of dietary fiber in all investigated groups and high consumption of cholesterol in men.

    Nutrition is an important component in the treatment of acute and chronic diseases and is a cornerstone in strategies for disease prevention and health promotion. Despite the acknowledged importance of nutrition, there is evidence to indicate that the nutrition training of medical students is inadequate in both quality and quantity. The study aimed to know the dietary/eating habits of medical students, assess their knowledge on nutrition and to assess their confidence in addressing the dietary issues of patients. It was a cross-sectional study conducted on final year medical students, interns and postgraduate students of Moti Lal Nehru Government Medical College, Allahabad. The sampling was purposive and a total of 218 participated in the study voluntarily. Overall 55% of the students were less knowledgeable and only 45% of them were more knowledgeable. Most (62%) postgraduates were more knowledgeable (p 0.340). Only 45.4% of them were confident in assessing the diet of patients and 44% of them were confident in recommending change of diet in patients. However this study shows no association between increase in the level of knowledge and confidence levels of the students (p > 0.339 and p > 0.109) suggesting that we need to incorporate innovative teaching methods to increase their confidence. Most students (79%) said that the medical curriculum was either just enough or not enough in preparing them to deal with the dietary issues of patients and 55% of them were of the opinion that the faculty should be trained in nutrition. The study results intend to stimulate active consideration of proper role of nutrition learning in medical education.

    Full Text Available In the present work we examined the ability of prenatally malnourished offspring to produce and maintain long-term potentiation (LTP of the perforant path/dentate granule cell synapse in freely moving rats at 15,30, and 90 days of age. Population spike amplitude (PSA was calculated from dentate field potential recordings prior to and at 15, 30, 60 min. and 3, 5, 18 and 24 h following tetanization of the perforant pathway. All animals of both malnourished and well-nourished diet groups at 15 days of age showed potentiation of PSA measures but the measures obtained from 15-day-old prenatally malnourished animals were significantly less than that of age-matched, well-nourished controls. At 30 days of age, remarkable effect of tetanization was likely observed from PSA measures for this age group followed much the same pattern. At 90 days of age, PSA measures obtained from malnourished animals decreased from pretetanization levels immediately following tetanization. At this age, however, at three hours time recordings, this measure growing up to a level which did not differ significantly from that of the control group. These results indicate that the width of tetanization induced enhancement of dentate granule cell response in preweanling rats (15-day-old animals is signifacantly affected fromgestational protein malnutrition and this trend is kept in animals tested at 30 and 90 days of age. The fact, however, that considerable limitation in LTP generation was gained from prenatally malnourished animals at 90 days of age, implying that dietary rehabilitation starting at birth is an intervention strategy not capable to imbrove the effects of the gestational stress.

    The relationship between cigarette smoking, vodka drinking and consumption of 44 food items typical of the Polish diet were analysed in a case-control study in Cracow, Poland, among 127 cases of breast cancer and 250 controls randomly selected from the general population. Cigarette smoking was not significantly influencing the breast cancer risk. Compared with never-drinkers, the habit of vodka drinking 20 years earlier significantly increased breast cancer risk in women below 50 years of age (multivariate OR was 4.4 with 95% CI 1.6-12.4). Frequent consumption of boiled vegetables 20 years earlier (greater than 3 times per week) was associated with a decreased risk of breast cancer in women aged 50 years and more (multivariate OR was 0.4 with 95% CI 0.2-0.8).

    Computational models have gained popularity as a predictive tool for assessing proposed policy changes affecting dietary choice. Specifically, they have been used for modeling dietary changes in response to economic interventions, such as price and income changes. Herein, we present a novel addition to this type of model by incorporating habitual behaviors that drive individuals to maintain or conform to prior eating patterns. We examine our method in a simulated case study of food choice behaviors of low-income adults in the US. We use data from several national datasets, including the National Health and Nutrition Examination Survey (NHANES), the US Bureau of Labor Statistics and the USDA, to parameterize our model and develop predictive capabilities in 1) quantifying the influence of prior diet preferences when food budgets are increased and 2) simulating the income elasticities of demand for four food categories. Food budgets can increase because of greater affordability (due to food aid and other nutritional assistance programs), or because of higher income. Our model predictions indicate that low-income adults consume unhealthy diets when they have highly constrained budgets, but that even after budget constraints are relaxed, these unhealthy eating behaviors are maintained. Specifically, diets in this population, before and after changes in food budgets, are characterized by relatively low consumption of fruits and vegetables and high consumption of fat. The model results for income elasticities also show almost no change in consumption of fruit and fat in response to changes in income, which is in agreement with data from the World Bank's International Comparison Program (ICP). Hence, the proposed method can be used in assessing the influences of habitual dietary patterns on the effectiveness of food policies.

    The objective of the present study was to observe the dietary patterns and food frequencies of type 2 diabetes patients attending the clinics of the Family Practice Center of the University of Sri Jayewardenepura, located in a highly urbanized area in Sri Lanka. An interviewer administered questionnaire based cross-sectional study was conducted among randomly selected 100 type 2 diabetes patients [age 35–70 years; mean age 55 ± 9 (males = 44; females = 56)]. The data were analyzed by SPSS version 18.0 software. Vegetables, fatty foods, and poultry consumption were in accordance with the national guidelines. A significant percentage (45.5%) consumed rice mixed meals for all three meals and only 67% consumed fruits at least once a day. Majority (71%) consumed full-cream milk and sugar intake (77%) was in accordance with the guidelines. Noncaloric sweetener usage was nonexistent. Daily green leafy vegetable intake and the quantity consumed were inadequate to obtain beneficial effects. From the study population, 44% [females 50%; males 36%] of the patients were either overweight or obese. However, only 60% of those patients accepted that they were either overweight or obese. Only 14% exercised daily while 69% never exercised. Study revealed the importance of educating patients with type 2 diabetes on dietary changes and more importantly the involvement in regular physical exercises. PMID:28127469

    2009-03-01

    Full Text Available Abstract Background Previous work showed that the functional cardiac effect of dietary alpha-linolenic acid (ALA in rats requires a long feeding period (6 months, although a docosahexaenoic (DHA acid-supply affects cardiac adrenergic response after 2 months. However, the total cardiac membrane n-3 polyunsaturated fatty acid (PUFA composition remained unchanged after 2 months. This delay could be due to a specific reorganization of the different subcellular membrane PUFA profiles. This study was designed to investigate the evolution between 2 and 6 months of diet duration of the fatty acid profile in sarcolemmal (SL, mitochondrial (MI, nuclear (NU and sarcoplasmic reticulum (SR membrane fractions. Methods Male Wistar rats were randomly assigned to 3 dietary groups (n = 10/diet/period, either n-3 PUFA-free diet (CTL, or ALA or DHA-rich diets. After 2 or 6 months, the subcellular cardiac membrane fractions were separated by differential centrifugations and sucrose gradients. Each membrane profile was analysed by gas chromatography (GC after lipid extraction. Results As expected the n-3 PUFA-rich diets incorporated n-3 PUFA instead of n-6 PUFA in all the subcellular fractions, which also exhibited individual specificities. The diet duration increased SFA and decreased PUFA in SL, whereas NU remained constant. The SR and MI enriched in n-3 PUFA exhibited a decreased DHA level with ageing in the DHA and CTL groups. Conversely, the n-3 PUFA level remained unchanged in the ALA group, due to a significant increase in docosapentaenoic acid (DPA. N-3 PUFA rich diets lead to a better PUFA profile in all the fractions and significantly prevent the profile modifications induced by ageing. Conclusion With the ALA diet the n-3 PUFA content, particularly in SR and SL kept increasing between 2 and 6 months, which may partly account for the delay to achieve the modification of adrenergic response.

    Diet and nutritional status have been shown to play pivotal roles in the occurrence of many chronic diseases. In this study, we examined the patterns of dietary habits and their relationships with risk factors for cardiovascular and chronic diseases in Hong Kong working populations. In April 2000, a 5-year territory-wide health promotion campaign supported by the Li Ka Shing Foundation was launched in Hong Kong by the Health InfoWorld of Hospital Authority. Between July 2000 and March 2002, 4841 Chinese subjects [2375 (49.1%) men and 2466 (50.9%) women, mean age: 42.4 +/- 8.9 years (median: 43.0 years, range: 17-83 years)] from the general working class were recruited. Subjects were randomly selected using computer generated codes according to the distribution of occupational groups. A dietary questionnaire was used to assess 6 core dietary habits: daily fruit intake, vegetable intake, fluid intake, sugary drinks, regularity of daily meals and number of dining out each day. Overall, men had a worse cardiovascular risk profile and less desirable dietary habits than women. Those who had more unhealthy dietary habits were more likely to be obese and current smokers. Using logistic regression analysis with the dietary habits as independent variables, we found that obesity, smoking and constipation were independently associated with various unhealthy dietary patterns. In conclusion, there were close associations between dietary habits and risk factors for cardiovascular diseases in Hong Kong. More effective community education about healthy lifestyle is required in Hong Kong.

This paper describes the methods of dietary assessment and presents preliminary findings on food and nutrient intakes in large general population samples in Russia, Poland and the Czech Republic. Methods The HAPIEE (Health, Alcohol and Psychosocial factors In Eastern Europe study examined random samples of men and women aged 45-69 years at baseline in Novosibirsk (Russia, Krakow (Poland and six Czech urban centres in 2002-2005. Diet was assessed using a food frequency questionnaire (at least 136 items; complete dietary information was available for 26,870 persons. Results Total energy intakes among men ranged between 8.7 MJ in the Czech sample and 11.7 MJ in the Russian sample, while among women, energy intakes ranged between 8.2 MJ in the Czech sample and 9.8 MJ in the Russian sample. A Healthy Diet Indicator (HDI, ranging from a score of 0 (lowest to 7 (highest, was developed using the World Health Organisation's (WHO guidelines for the prevention of chronic diseases. The mean HDI scores were low, ranging from 1.0 (SD = 0.7 among the Polish subjects to 1.7 (SD = 0.8 among the Czech females. Very few subjects met the WHO recommended intakes for complex carbohydrates, pulses or nuts; intakes of saturated fatty acids, sugar and protein were too high. Only 16% of Polish subjects met the WHO recommendation for polyunsaturated fat intake. Consumption of fruits and vegetables was lower than recommended, especially among those Russian subjects who were assessed during the low intake season. Fewer than 65% of subjects consumed adequate amounts of calcium, magnesium and potassium, when compared with the United Kingdom's Reference Nutrient Intake.

    Full Text Available Abstract Background Pediatric obesity has become a global public health problem. Data on the lifestyle behaviors, dietary habits, and familial factors of overweight and obese children and adolescents are limited. The present study aims to compare health-related factors among normal-weight, overweight, and obese Chinese children and adolescents. Methods We conducted a cross-sectional study consisted of 4262 children and adolescents aged 5–18 years old from rural areas of the northeast China. Anthropometric measurements and self-reported information on health-related variables, such as physical activities, sleep duration, dietary habits, family income, and recognition of weight status from the views of both children and parents, were collected by trained personnel. Results The prevalence rates of overweight and obesity were 15.3 and 6.4%, respectively. Compared to girls, boys were more commonly overweight (17.5% vs. 12.9% and obese (9.5% vs. 3.1%. Approximately half of the parents with an overweight or obese child reported that they failed to recognize their child’s excess weight status, and 65% of patients with an overweight child reported that they would not take measures to decrease their child’s body weight. Obese children and adolescents were more likely to be nonsnackers [odds ratio (OR: 1.348; 95% confidence interval (CI: 1.039–1.748] and to have a family income of 2000 CNY or more per month (OR: 1.442; 95% CI: 1.045–1.99 and less likely to sleep longer (≥7.5 h (OR: 0.475; 95% CI: 0.31–0.728 than the normal-weight participants. Conclusions Our study revealed a high prevalence of overweight and obesity in a large Chinese pediatric population. Differences in sleep duration, snacking, family income, and parental recognition of children’s weight status among participants in different weight categories were observed, which should be considered when planning prevention and treatment programs for pediatric obesity.

  13. The dietary basis for temporal partitioning: food habits of coexisting Acomys species.

    Kronfeld-Schor, Noga; Dayan, Tamar

    1999-10-01

    Two rodent species of the genus Acomys coexist on rocky terrain in the southern deserts of Israel. The common spiny mouse (A. cahirinus) is nocturnally active whereas the golden spiny mouse (A. russatus) is diurnally active. An early removal study suggested that competition accounts for this pattern of temporal partitioning: the golden spiny mouse is forced into diurnal activity by its congener. Theoretically, temporal segregation should facilitate coexistence if the shared limiting resources differ at different times (primarily among predators whose prey populations have activity rhythms), or if they are renewed within the period of the temporal segregation. We studied food preferences of the two Acomys species in a controlled cafeteria experiment in order to assess resource overlap and the potential for competition for food between the two species. We found no significant difference in food preferences between species. The dietary items preferred by both were arthropods. We also carried out a seasonal study of the percentage and identity of arthropods taken in the field by individuals of the two species. Individuals of both species took on annual average a high percentage of arthropods in their diets. Seasonal diet shifts reflect seasonal abundance of arthropods at Ein Gedi during day and night. Diurnal activity may also reduce interspecific interference competition between A. russatus and A. cahirinus. However, the strong interspecific dietary overlap in food preference, the heavy reliance on arthropods in spiny mouse diets, and the seasonal and circadian differences in arthropod consumption suggest that prey partitioning may be a viable mechanism of coexistence in this system.

    Severe shock is a life-threatening condition with very high short-term mortality. Whether the long-term outcomes among survivors of severe shock are similar to long-term outcomes of other critical illness survivors is unknown. We therefore sought to assess long-term survival and functional outcomes among 90-day survivors of severe shock and determine whether clinical predictors were associated with outcomes. Seventy-six patients who were alive 90 days after severe shock (received ≥1 μg/kg per minute of norepinephrine equivalent) were eligible for the study. We measured 3-year survival and long-term functional outcomes using the Medical Outcomes Study 36-Item Short-Form Health Survey, the EuroQOL 5-D-3L, the Hospital Anxiety and Depression Scale, the Impact of Event Scale-Revised, and an employment instrument. We also assessed the relationship between in-hospital predictors and long-term outcomes. The mean long-term survival was 5.1 years; 82% (62 of 76) of patients survived, of whom 49 were eligible for follow-up. Patients who died were older than patients who survived. Thirty-six patients completed a telephone interview a mean of 5 years after hospital admission. The patients' Physical Functioning scores were below U.S. population norms (P shock had a high 3-year survival rate. Patients' long-term physical and psychological outcomes were similar to those reported for cohorts of less severely ill intensive care unit survivors. Anxiety and depression were relatively common, but only a few patients had symptoms of posttraumatic stress disorder. This study supports the observation that acute illness severity does not determine long-term outcomes. Even extremely critically ill patients have similar outcomes to general intensive care unit survivor populations.

    Candida albicans being a part of the normal oral microbial flora is one of the most commonly isolated species from the oral cavity. Recent studies have shown a steady rise in the number of non C. albicans species, which are relatively resistant to common antifungal agents and are being recognized as potential pathogens. It is vital to ascertain the predisposing factors leading to such a shift in the oral candidal flora. To estimate the prevalence of candidal species among vegetarians and non-vegetarians. Clinical data including age, gender, and diet preference of 238 participants were noted. Participants with a history of systemic disorders, oral prosthesis, salivary gland disorders and habits such as smoking, alcoholism, and tobacco usage were excluded from the study. The participants were asked to gargle a 10 ml solution of phosphate buffered saline for one minute before depositing the same in a sterile container. The samples were cultured using Hicrome agar media. Data analysis was carried out using Statistical Package for Social Sciences (SPSS software) version 10.5 and differences between individual groups were tested by Chi-square test. Among 238 samples, 127 (53.3%) samples were positive for Candida. The candidal prevalence in vegetarians (68.5%) was higher than non-vegetarians (40.7%). C. albicans was the most common species to be isolated in both vegetarians (35.1%) and non-vegetarians (39.2%). Candida glabrata and Candida tropicalis showed a higher prevalence in vegetarians (30.5% and 10.1%, respectively) in comparison to non-vegetarians (8.4% and 2.3%, respectively). Candida krusei was isolated only from vegetarians (4.6%). Results indicate that diet plays a major role in oral candidal prevalence and species specificity which in turn may predispose the vegetarians toward these pathogenic organisms.

    The goal of this study was to explore attitudes and habits of Serbian preschool and school children in consumption of meat products, milk and milk products, eggs and egg products and honey and bee products. The survey was conducted on a sample of 227 children, divided into three different age groups: preschool (ages 4-6), primary school I-IV grade (ages 7-11) and primary school V-VIII grade (ages 12-15). The results showed that all examined groups of children consumed meat products, milk and milk products, eggs and egg products, and honey and bee products. In all groups of children, the most frequently consumed food (among our food category choices) was dried ham (consumed by 19.64% of preschool children; 23.75% of schoolchildren from I-IV grade; 19.74% of schoolchildren from V-VIII grade). Fewer preschool children consumed sterilized milk compared to children of school age. The results showed that in all three groups of children, the most commonly consumed milk products were yoghurt (from 12.20 to 15.29% of children consumed these) and sour cream (from 11.57 to 12.74% of children consumed this), while kefir was the least-consumed product. In addition, there was no difference in consumption of boiled or fried eggs in the examined groups of children, while the consumption of egg products (mayonnaise) was higher in the group of preschool children than in the group of schoolchildren from V-VIII grade. Preschool children consumed honey 14.99% more often than schoolchildren from I-IV grade, and 14.49% more often than did schoolchildren from grade V-VIII.

    The study investigates the prevalence of overweight and obesity in a population of intellectually disabled (ID) adolescents. An observational study was conducted on a group of 410 ID children, living in France. Overweight and obesity, defined according to international standards, were analyzed and related to demographic and sociological parameters, educational care, physical activity and dietary habits. The study highlighted a high prevalence of overweight and obesity (19.0%) in ID adolescents and 22.5% in oldest teenagers, age 15-20 y. This observation was more likely in medico-educative institutes (25.1%) than in general schools (12.3%). Average time spent in physical activity was 4.5 h/week, compared with 3.5 h/week in obese subjects. Time spent in sedentary behavior was 26.6 h/week for the whole population, compared with 18.6 h/week in obese adolescents. Meals were ingested regularly, and adherence to eating breakfast was good. However, snacks and soft drinks were consumed between and during meals by 66.5% of subjects. Overweight in young ID appeared to be related to parental overweight. Even though ID adolescents receive a balanced diet and practice sport regularly, they exhibit a high prevalence for overweight and obesity. In subjects more than 15 years of age, enrollment in medico-educative institutes and parental overweight were contributory factors to poor weight status. Copyright © 2010 Elsevier Ltd.

    Full Text Available Background: Obesity and the metabolic syndrome affect a considerable segment of the population worldwide, including health professionals. In fact, several studies have reported that physicians tend to have more cardiovascular risk factors than their patients. The present cross-sectional study assessed whether the Health Sciences students had a healthier lifestyle, thus could have a more preventive attitude towards chronic diseases than the general population. Materials and methods: Students of the medical-biological areas were surveyed by answering a questionnaire about familiar cardiovascular risk factors, personal smoking, alcohol drinking, dietary and exercise habits. Blood pressure was also measured, along with weight, height, and abdominal circumference. Results: 23.4% of the participants were overweight and 10% obese. Parental obesity was the most frequent risk factor, followed by social drinking and smoking. We found high consumption of animal derived foods, breakfast-like cereals, pastries, white bread and sweetened beverages; while low intake of fruit and vegetables were reported. More than half the sample reported to practice very little or no exercise at all. Discussion and conclusions: We found similar or even higher rates of risk factors than the average population, that may eventually lead to the development of chronic cardiometabolic diseases. Thus we can infer that biomedical education is inefficient in inducing healthy lifestyles among biomedical students, which could have impact in their future practice as they will most probable become obese health-professionals, thus fail to effectively treat their own patients.

    2012-12-01

    Full Text Available The moderate consumption of fish is recommended for a healthy diet and is also a feature of the Mediterranean diet. Fish is a major food group in diets throughout the world, and studies show that fish consumption is associated with a lower risk of a number of conditions. Spain has one of the highest annual per capita consumptions of fish worldwide. As fish is a source of high quality protein; n-3 polyunsaturated fatty acids; vitamins, such as A and D; and minerals, such as selenium, calcium, iodine, magnesium, copper and zinc, nutrients that have positive effects on bone characteristics, it has been proposed that its consumption could improve bone health. In this cross-sectional study, we have investigated the relationship between dietary habits and nutrient intake of 151 Spanish premenopausal women and analyzed the association of fish consumption on bone mass measured by quantitative ultrasound of the phalanges. A higher (P < 0.05 bone mass and vitamin D intake (P < 0.05 was observed in the group with a fish intake of 5–7 servings/week. We conclude that increased fish consumption is helpful in maintaining an adequate bone mass in Spanish premenopausal women.

    This study aims at describing and interpreting concentration profiles of trace elements in seven Antarctic fish species (N = 132 specimens) off Adélie Land. Ichthyofauna plays a key role in the Antarctic ecosystem, as they occupy various ecological niches, including cryopelagic (ice-associated), pelagic, and benthic habitats. Firstly, trace element levels in the studied specimens were similar to those previously observed in fish from the Southern Ocean. Apart from manganese and zinc, concentrations of arsenic, cadmium, copper, iron, mercury (Hg), nickel, selenium and silver differed among fish species. Muscle δ{sup 13}C and δ{sup 15}N values were determined to investigate whether the fish foraging habitats and dietary habits could explain Hg levels. Species and foraging habitat (δ{sup 13}C) were strong predictors for variations of Hg concentrations in muscle tissues. The highest Hg contamination was found in shallow benthic fish compared to cryopelagic and pelagic fish. This pattern was likely due to the methylation of Hg in the coastal sediment and the photodemethylation by ultraviolet radiation in surface waters. - Highlights: • Trace elements and stable isotopes were analyzed in seven Antarctic fish species. • Levels of trace elements in liver and in muscle differed among species. • Hg load was higher in benthic fish than in cryopelagic and pelagic fish. • These findings could be due to the high methylation rate of Hg in the sediment.

    Full Text Available Abstract Background Prevalence of men with cardiometabolic risk factors (CMRF is increasing in Japan. Few studies have comprehensively examined the relation between lifestyles and CMRF. Methods We examined the baseline data from 3,498 male workers ages 19 to 69 years who participated in the high-risk and population strategy for occupational health promotion (HIPOP-OHP study at 12 large-scale companies throughout Japan. The physical activity of each participant was classified according to the International Physical Activity Questionnaire (IPAQ. Dietary intake was surveyed by a semi-quantitative Food Frequency Questionnaire. We defined four CMRF in this study as follows: 1 high blood pressure (BP: systolic BP ≥ 130 mmHg, or diastolic BP ≥ 85 mmHg, or the use of antihypertensive drugs; 2 dyslipidemia: high-density lipoprotein-cholesterol concentration 2. Results Those who had 0 to 4 CMRF accounted for 1,597 (45.7%, 1,032 (29.5%, 587 (16.8%, 236 (6.7%, and 44 (1.3% participants, respectively, in the Poisson distribution. Poisson regression analysis revealed that independent factors that contributed to the number of CMRF were age (b = 0.020, P Conclusions Alcohol intake, percent protein and total energy intake were positively associated, whereas drinking frequency and IPAQ were inversely associated, with the number of CMRF.

    Research about the prevalence of underweight and overweight/obesity in the Saudi Arabian female population is limited. The aim of the present study was to examine the dietary habits and the prevalence of underweight and overweight/obesity and associated factors among female university students. A cross-sectional study. A university centre for female students in south-western Saudi Arabia. The study involved 663 randomly selected female university students who self-reported their physical activities, nutritional habits and socio-economic factors. Multiple linear and logistic regression analyses were used to identify factors associated with the students' BMI, dietary variables, underweight and overweight/obesity. The majority of the university females were normal weight (56.9%), but a high prevalence of underweight (19.2%) and overweight/obesity (23.8%) occurred. Social factors significantly associated with BMI were the presence of obese parents and siblings as well as physical activity levels, marital status, number of sisters, father's level of education and more frequent intake of French fries/potato chips (>3 times/week). Several variables were found to correlate with dietary habits, underweight and overweight/obesity. Of special interest is the association between the number of siblings and the participants' BMI and dietary intake in both negative and positive ways. The findings of this research have implications for health promotion and prevention of malnutrition among college-aged females. Health-care providers and policy makers need to involve the whole family when promoting females' physical activity. The study serves as an evidence-based background for planning and implementation of interventions targeting improvement of highly educated populations' nutritional habits.

    Full Text Available Because of their unique morphological and ecological characteristics (i.e. being obligate carnivorous, solitary, and ingesting their prey whole, snakes are expected to show unusual dietary patterns compared to other ectothermic vertebrates, and the best way to explore this is to analyse the snake dietary patterns globally. Here I review and analyse the peer-reviewed snake diet literature available in order to explore whether there are broad patterns in the interpopulation variability of diet composition in these unique ectothermic predators. I collated data for 181 independent populations belonging to 58 species of snakes from some of the main families (1 Boidae, 2 Pythonidae, 27 Colubridae, 10 Elapidae, and 18 Viperidae and from all the continents (4 from South and Central America, 13 from North America, 12 from Europe, 18 from Africa, 4 from Asia, and 7 from Australia. All these populations satisfied some precise criteria of inclusion, and were therefore re-analysed in a comparative perspective. I classified each literature entry according to 1 snake species, 2 snake family, 3 geographic position (continent of the study areas, 4 climatic region (temperate versus tropical, 5 guild (if the species is aquatic, terrestrial, or arboreal, 6 hunting strategy (sit-and-wait versus active forager, and 7 venom (if the species is venomous or not. All these seven factors were analysed by GLM procedures to evaluate their effects on the interpopulation diet variation within snake species, that was assessed by using a univariate similarity index. The various taxonomical categories of snake prey were grouped according to two different levels of taxonomic affinity: a general affinity, e.g. frogs and toads, salamanders, lizards, birds, etc., and b close affinity, by grouping prey types belonging to a same genus. My study revealed that, within-species snake populations showed a very low variability in terms of diet composition. As for the general affinity

    The strong social pressure for thinness in Japanese society has produced a dramatic increase in underweight (body mass index: dietary habits and other lifestyle variables, including the desire for thinness, were obtained through a self-administered questionnaire survey conducted at 54 academic institutions in Japan, from which we selected 3634 female students for analysis. The subjects were divided into three groups of normal weight (84.3%), and underweight with (6.4%) or without (9.3%) a desire for thinness. After adjusting for potential confounders, the underweight subjects with a desire for thinness consumed less cereal and rice, whereas those without a desire for thinness consumed more cereal and rice than the normal weight subjects. In addition, those without a desire for thinness consumed less confectionaries, including candies and ice cream, and less fats and oils than the normal weight subjects. These results suggest that dietary habits differ between underweight women with and without a desire for thinness. Although both groups require nutritional education to maintain appropriate body weight, underweight women with a desire for thinness require particular attention to improve recognition of their constitution and dietary habits.

    Full Text Available The number of long-term survivors is increasing in the western countries due to remarkable improvements in the treatment of childhood cancer. The long-term complications of childhood cancer survivors in these countries were brought to light by the childhood cancer survivor studies. In Korea, the 5-year survival rate of childhood cancer patients is approaching 70%; therefore, it is extremely important to undertake similar long-term follow-up studies and comprehensive long-term care for our population. On the basis of the experiences of childhood cancer survivorship care of the western countries and the current Korean status of childhood cancer survivors, long-term follow-up study and long-term care systems need to be established in Korea in the near future. This system might contribute to the improvement of the quality of life of childhood cancer survivors through effective intervention strategies.

    Polars are cataclysmic variables with the highest magnetic field strengths (10-250 MG). Matter is accreted after being funneled by the strong magnetic field of the white dwarf. We perform a meta-study of multi-wavelength data of polars. Many polars have been observed in surveys, such as SDSS, 2MASS, ROSAT, just to name a few. Some polars have now been detected by the JVLA, part of an expanding class of radio CVs. A large subset of polars have long-term optical light curves from CRTS and AAVSO. We suggest that the long term light curves of polars display a variety of signature behaviors and may be grouped accordingly. Additional characteristics such a binary period, magnetic field strengths, X-ray properties, and distance estimates are examined in context with long-term observations.

Results were evaluated using the concept of majority and minority group and presented in a sequential way: teachers' perceptions about eating habits, barriers to healthy eating, teacher's culinary habits, abilities to teach students healthy eating habits through Information and Communication Technologies, and cooking activities. Teachers' eating habits were poor, with lack of time, money, and will to improve. They had culinary habits skills and the desire to instruct and guide their students in eating healthier food. They need a program with Information and Communication Technologies and cooking workshops to apply in the classroom.

    The dietary patterns of immigrants usually change with the duration of residence and progressively resemble those of the host country. However, very few studies have investigated individuals migrating to countries with a high-quality diet, such as the Mediterranean diet (MD), and none has yet focused on Latin-American immigrants. The present study examined the association of the duration of residence with obesity-related eating habits and dietary patterns among Latin-American immigrants residing in Spain. A cross-sectional study was conducted in 2008-10 in a representative sample of the adult population residing in Spain. Adherence to the MD was defined as a MD Adherence Screener score ≥ 9. Analyses were conducted by including 419 individuals aged 18-64 years born in Latin-American countries. Compared with immigrants residing in Spain for unhealthy changes in some eating habits and dietary patterns among Latin-American immigrants. Some of the healthy changes observed contrasted the 'Westernisation' of the diet reported in studies conducted in other Western countries. The results of the present study support the role of the food environment of the host country in the modification of the dietary patterns of immigrants.

    Gamst, Mette; Jensen, Thomas Sejr

    In several countries, home care is provided for certain citizens living at home. The long-term home care scheduling problem is to generate work plans spanning several days such that a high quality of service is maintained and the overall cost is kept as low as possible. A solution to the problem...... provides detailed information on visits and visit times for each employee on each of the covered days. We propose a branch-and-price algorithm for the long-term home care scheduling problem. The pricing problem generates one-day plans for an employee, and the master problem merges the plans with respect...

    Several situations are potentially painful for fetuses, such as malformations and invasive procedures. Nociceptive pathways are known to be functional at 26 weeks. Even if it is not possible to evaluate the fetal experience of pain, it is essential to examine its immediate and long-term consequences. As early as the beginning of the second trimester, hemodynamic and hormonal responses are observed following fetal nociceptive stimulation, In experimental studies, long-term changes have been noted in the corticotrop axis, subsequent responses to pain, and behavior after perinatal nociceptive stimulation.

    A keratoprosthesis (KP), is an artificial cornea which is inserted into an opacified cornea in an attempt to restore useful vision or, less commonly, to make the eye comfortable in painful keratopathy. Results o a retrospective study of 35 patients, with 55 KP insertions, are reviewed with regard to visual acuity, length of time vision is maintained, retention time, and complication. Overall there were a number of long-term real successes, eith retention of the KP and maintenance of improved vision in eyes not amenable to conventional treatment. Careful long-term follow-up was needed, with further surgical procedures often being necessary.

    To develop and evaluate the effectiveness of a parental support programme to promote healthy dietary and physical activity habits and to prevent overweight and obesity in Swedish children. A cluster-randomised controlled trial was carried out in areas with low to medium socio-economic status. Participants were six-year-old children (n = 243) and their parents. Fourteen pre-school classes were randomly assigned to intervention (n = 7) and control groups (n = 7). The intervention lasted for 6 months and included: 1) Health information for parents, 2) Motivational Interviewing with parents and 3) Teacher-led classroom activities with children. Physical activity was measured by accelerometry, dietary and physical activity habits and parental self-efficacy through a questionnaire. Body weight and height were measured and BMI standard deviation score was calculated. Measurements were conducted at baseline, post-intervention and at 6-months follow-up. Group differences were examined using analysis of covariance and Poisson regression, adjusted for gender and baseline values. There was no significant intervention effect in the primary outcome physical activity. Sub-group analyses showed a significant gender-group interaction in total physical activity (TPA), with girls in the intervention group demonstrating higher TPA during weekends (p = 0.04), as well as in sedentary time, with boys showing more sedentary time in the intervention group (p = 0.03). There was a significantly higher vegetable intake (0.26 servings) in the intervention group compared to the control group (p = 0.003). At follow-up, sub-group analyses showed a sustained effect for boys. The intervention did not affect the prevalence of overweight or obesity. It is possible to influence vegetable intake in children and girls' physical activity through a parental support programme. The programme needs to be intensified in order to increase effectiveness and sustain the effects long-term. These findings are an

    The incidence of traffic accidents in patients with chronic liver disease (CLD) is high in the USA. However, the characteristics of patients, including dietary habits, differ between Japan and the USA. The present study investigated the incidence of traffic accidents in CLD patients and the clinical profiles associated with traffic accidents in Japan using a data-mining analysis. A cross-sectional study was performed and 256 subjects [148 CLD patients (CLD group) and 106 patients with other digestive diseases (disease control group)] were enrolled; 2 patients were excluded. The incidence of traffic accidents was compared between the two groups. Independent factors for traffic accidents were analyzed using logistic regression and decision-tree analyses. The incidence of traffic accidents did not differ between the CLD and disease control groups (8.8 vs. 11.3%). The results of the logistic regression analysis showed that yoghurt consumption was the only independent risk factor for traffic accidents (odds ratio, 0.37; 95% confidence interval, 0.16-0.85; P=0.0197). Similarly, the results of the decision-tree analysis showed that yoghurt consumption was the initial divergence variable. In patients who consumed yoghurt habitually, the incidence of traffic accidents was 6.6%, while that in patients who did not consume yoghurt was 16.0%. CLD was not identified as an independent factor in the logistic regression and decision-tree analyses. In conclusion, the difference in the incidence of traffic accidents in Japan between the CLD and disease control groups was insignificant. Furthermore, yoghurt consumption was an independent negative risk factor for traffic accidents in patients with digestive diseases, including CLD.

    The Republic of Palau belongs to Micronesia, and obese people and lifestyle-related diseases are prevalent there. We investigated the relationship of dietary habits and obesity to oxidative stress in Palauan people, as compared with those of Japanese and Mongolian people. A total of 126 healthy Palauan subjects were enrolled. Oxidative stress was evaluated by serum level of reactive oxygen metabolites (ROM). Antioxidant capacity was evaluated by serum level of biological antioxidant potential (BAP). In Palauan subjects, BMI> or =30 was observed in 45.0% of males and 59.1% of females (Japanese: males 1.3%, females 0.8%, Mongolian: males 6.3%, females 14.7%). Palauan subjects consumed 2553 kcal per day (Japanese 2121 kcal, Mongolians 2534 kcal). The ratios of carbohydrate energy to total energy were 59.8 % (Japanese 54.7 %, Mongolians 50.2%). The ratios of fat energy to total energy were 22.9% (Japanese 26.7%, Mongolians 34.5%). ROM levels in Palauan subjects showed higher than those in Japanese subjects, while BAP levels of Palauan subjects did not decrease compared to those of Japanese. ROM levels correlated with body fat ratio, and showed a reverse correlation with handgrip strength. Handgrip strength decreased in the subjects of more than forty years of age. These findings suggest that the obesity in Palauan people may have a connection with high intake of calories through carbohydrate eating rather than through fat eating. Their high oxidative stress may be induced by obesity, and contribute to an early decline of handgrip strength, ultimately in early aging.

    Because excessive consumption of sugar-sweetened beverages may reduce the quality of nutritional intake, this study examined the consumption patterns of commercial beverages, lifestyle, dietary habits, and perception of sweet taste. Participants were 407 male university students in Kyeonggido, Korea, and information was collected by self-administered questionnaire. Among them, 58 nonsmokers volunteered to participate in the taste test. Participants were divided into three groups according to the frequency of commercial beverage consumptions: 120 rare ( 3 servings/week) consumption groups. More subjects from the rare consumption group chose water, tea, and soy milk, and more from the frequent consumption group chose carbonated soft drinks and coffee (P = 0.031) as their favorite drinks. Frequent consumption group consumed fruit juice, coffee, and sports and carbonated soft drinks significantly more often (P = 0.002, P = 0.000, P = 0.000, respectively), but not milk and tea. Frequent consumption group consumed beverages casually without a specific occasion (P = 0.000) than rare consumption group. Frequent drinking of commercial beverages was associated with frequent snacking (P = 0.002), meal skipping (P = 0.006), eating out (P = 0.003), eating delivered foods (P = 0.000), processed foods (P = 0.001), and sweets (P = 0.002), and drinking alcoholic beverages (P = 0.029). Frequent consumption group tended to have a higher threshold of sweet taste without reaching statistical significance. The results provide information for developing strategies for evidence-based nutrition education program focusing on reducing consumption of unnecessary sugar-sweetened commercial beverages.

    To explore socio-economic differences in use of staff canteens and whether frequent use of staff canteens is associated with different food patterns and obesity. Cross-sectional study using three self-administered questionnaires, two of them including food frequency questions. Factor analysis was used to explore food patterns. Oslo, Norway, 2000-2001. In total 8943 adult, working Oslo citizens. Frequent (≥3 times/week) use of staff canteens was most likely among men, younger workers and those in the highest education and income groups. However, after adjustment for demographic, socio-economic and lifestyle factors, those with highest education were least likely to use staff canteens frequently. Frequent eating in staff canteens was positively associated with a Western food pattern (based on fat-rich food, fast food and red meat) and inversely associated with a traditional food pattern (based on boiled potatoes and gravy, and less rice, pasta and oil) in multivariate analyses. Unadjusted, frequent eating in staff canteens was also inversely associated with a prudent food pattern (based on fruit, vegetables, fish, legumes and oil). The likelihood of being obese (BMI ≥ 30 kg/m2) increased significantly with frequent eating in staff canteens, also when adjusted for demographic and socio-economic variables. Adjustment for the food patterns attenuated this relationship, but it was still significant. Frequent eating in staff canteens was negatively related to socio-economic position and positively associated with unhealthy dietary habits. This partly explained higher odds for obesity among frequent users of staff canteens. Future research should assess the availability and food options of staff canteens.

    AIM To analyze the association between oncohematological diseases and GSTT1/GSTM1/CYP1A1 polymorphisms, dietary habits and smoking, in an argentine hospital-based case-control study. METHODS This hospital-based case-control study involved 125 patients with oncohematological diseases and 310 control subjects. A questionnaire was used to obtain sociodemographic data and information about habits. Blood samples were collected, and DNA was extracted using salting out methods. Deletions in GSTT1 and GSTM1 (null genotypes) were addressed by PCR. CYP1A1 MspI polymorphism was detected by PCR-RFLP. Odds ratio (OR) and 95%CI were calculated to estimate the association between each variable studied and oncohematological disease. RESULTS Women showed lower risk of disease compared to men (OR 0.52, 95%CI: 0.34-0.82, P = 0.003). Higher levels of education (> 12 years) were significantly associated with an increased risk, compared to complete primary school or less (OR 3.68, 95%CI: 1.82-7.40, P tobacco, none of the smoking categories showed association with oncohematological diseases. Regarding dietary habits, consumption of grilled/barbecued meat 3 or more times per month showed significant association with an increased risk of disease (OR 1.72, 95%CI: 1.08-2.75, P = 0.02). Daily consumption of coffee also was associated with an increased risk (OR 1.77, 95%CI: 1.03-3.03, P = 0.03). Results for GSTT1, GSTM1 and CYP1A1 polymorphisms showed no significant association with oncohematological diseases. When analyzing the interaction between polymorphisms and tobacco smoking or dietary habits, no statistically significant associations that modify disease risk were found. CONCLUSION We reported an increased risk of oncohematological diseases associated with meat and coffee intake. We did not find significant associations between genetic polymorphisms and blood cancer.

    Jang, Bo-An

    2016-04-01

    The greenschist in the Jinping II Hydropower Station in southwest China exhibits continuous creep behaviour because of the geological conditions in the region. This phenomenon illustrates the time-dependent deformation and progressive damage that occurs after excavation. In this study, the responses of greenschist to stress over time were determined in a series of laboratory tests on samples collected from the access tunnel walls at the construction site. The results showed that the greenschist presented time-dependent behaviour under long-term loading. The samples generally experienced two stages: transient creep and steady creep, but no accelerating creep. The periods of transient creep and steady creep increased with increasing stress levels. The long-term strength of the greenschist was identified based on the variation of creep strain and creep rate. The ratio of long-term strength to conventional strength was around 80% and did not vary much with confining pressures. A quantitative method for predicting the failure period of greenschist, based on analysis of the stress-strain curve, is presented and implemented. At a confining pressure of 40 MPa, greenschist was predicted to fail in 5000 days under a stress of 290 MPa and to fail in 85 days under the stress of 320 MPa, indicating that the long-term strength identified by the creep rate and creep strain is a reliable estimate.

    Full Text Available Objectives: To assess the magnitude of obesity and overweight among male primary school children, and to find the possible association between obesity/overweight and dietary habits and sociodemographic differentials among them. Study design and Methods: A cross-sectional descriptive study, including 1139 Saudi male children enrolled in the 5 th and 6 th grades in public primary schools in Al Hassa, Kingdom of Saudi Arabia (KSA, was conducted. The test included a multistage random sampling technique, based on interview using Youth and Adolescent Food Frequency Questionnaire, gathering data regarding dietary intake, dietary habits, followed by anthropometric measurements with the calculation of body mass index (BMI, the interpretation of which was based on Cole′s tables for the standard definition of overweight and obesity. Sociodemographic data were collected through a parental questionnaire from. Data analysis was performed using the SPSS 12 software (SPSS Inc. Chicago, IL, USA; both univariate and multivariate analyses were performed. Results: The age of the school children ranged from 10-14 years. The prevalence of overweight among the subjects was 14.2%, while that of obesity was 9.7%; the prevalence was more in the urban, older age students. The mothers of obese and overweight children were less educated and more working. Missing and or infrequent intake of breakfast at home, frequent consumption of fast foods, low servings per day of fruits, vegetables, milk and dairy products, with frequent consumption of sweets/candy and carbonated drinks were all predictors of obesity and overweight among the schoolchildren studied. Conclusion: The prevalence of childhood obesity is escalating and approaching figures that have been reported till now from the developed countries. Less healthy dietary habits and poor selection of food may be responsible for this high prevalence.

  4. Palila Restoration: Lessons from Long-term Research

    2006-01-01

    BACKGROUND The palila (Loxioides bailleui) is a member of the Hawaiian honeycreeper family of birds (Drepanidinae), which is renowned for the profusion of species - many with bizarre bills and specialized feeding habits - that radiated from a single ancestral type. Most of the 57 or so honeycreeper species are extinct, and the palila is endangered because of its high degree of dependence on the mamane tree (Sophora chrysophylla) (Figure 1) and its restricted distribution on the upper slopes of Mauna Kea (Figure 2). Three decades of research have revealed many important facts about palila, providing the foundation and impetus for conservation programs in the wild and captivity. Additionally, an ambitious public conservation campaign arose due to the land-use conflicts on Mauna Kea. Here we summarize progress in palila conservation biology and outline steps that might overcome the remaining major challenges to its recovery. We also highlight lessons learned from palila research that may help the recovery of other Hawaiian forest birds. Palila and two closely-related species on the tiny islands of Nihoa and Laysan are the last of the seed-eating honeycreeper species in the Hawaiian Islands. About a quarter of the honeycreeper species known from living and fossil specimens had finch-like bills suited mainly for eating seeds and fruits. Because of their dietary specialization, palila are vulnerable to changes in forest size and quality, as was also likely the case for extinct species of seed specialists. Palila and many other forest bird species were once distributed in dry, lowland forests. Fossil records indicate that palila also occurred in the lowlands of O`ahu and Kaua`i until human settlement of those islands. However, because lowland habitats have been highly modified by humans and because mamane occurs today primarily at high elevation, palila are the only native bird species found exclusively in dry, subalpine habitat (2000?2850 m). Similar to other feeding

    The National Aeronautics and Space Administration (NASA) is focused on developing technologies for extending human presence beyond low Earth orbit. These technologies are to advance the state-of-the-art and provide for longer duration missions outside the protection of Earth's magnetosphere. One technology of great interest for large structures is advanced composite materials, due to their weight and cost savings, enhanced radiation protection for the crew, and potential for performance improvements when compared with existing metals. However, these materials have not been characterized for the interplanetary space environment, and particularly the effects of high energy radiation, which is known to cause damage to polymeric materials. Therefore, a study focusing on a lunar habitation element was undertaken to investigate the integrity of potential structural composite materials after exposure to a long-term lunar radiation environment. An overview of the study results are presented, along with a discussion of recommended future work.

  6. Seafloor Weathering As a Long-Term Climate Regulation Mechanism

    2014-12-01

    The global carbon cycle determines the distribution of carbon between the atmosphere, ocean, and solid earth. Carbon from the mantle enters the Earth's surficial environment as CO2 by volcanic outgassing, and carbon is buried in the oceanic crust as carbonate rocks during silicate rock weathering. The subduction of carbonate-rich oceanic plates returns carbon to the mantle, closing the cycle. Subtle adjustments in continental silicate weathering, widely held to consume atmospheric CO2 at a rate controlled by climate, are believed to have maintained habitable conditions throughout Earth's history. This long term climate regulation mechanism is known as a climate-weathering feedback. Seafloor weathering, low-temperature basalt alteration and carbonate precipitation in the permeable upper oceanic crust, has been proposed as a climate-weathering feedback as well, but the link to climate is presently poorly understood. Such a climate regulation mechanism would be particularly important on waterworld planets where continental silicate weathering cannot regulate climate. It has so far not been possible to determine whether changes in seafloor weathering could contribute to climate regulation on Earth or in a waterworld scenario because the necessary modeling framework has not yet been developed. However, advances in porous media flow modeling and reactive transport modeling, as well as the availability of inexpensive computational power, allow the seafloor weathering problem to be looked at in greater detail. We have developed a spatially resolved two-dimmensional (2D) numerical model of seafloor weathering in the permeable upper oceanic crust. This model simulates 2D off-axis hydrothermal flow coupled to geochemical alteration of seafloor basalt by modeling reactive transport of chemical species in seawater-derived hydrothermal fluids. The focus of this research is to use the model to determine the effect of geological and climatic factors on seafloor weathering, which

    We examined the effects of sedentary lifestyle and dietary habits on body mass index (BMI) change in a follow-up study of 325 women (aged 15-49 years) in Delhi, systematically selected from the 1998-1999 National Family Health Survey samples who were re-interviewed after 4 years in 2003. Information was collected on height, weight, dietary habits, and sedentary lifestyle through face-to-face interviews. Overall, a 2.0-point increase in mean BMI was found among women in just 4 years. Every second normal-BMI woman, two in five overweight women, and every fourth obese woman experienced a > 2.0-point increase in her mean BMI. High sedentary lifestyle (OR: 2.63; 95% CI: 1.29-5.35) emerged as the main predictor of a > 2.0-point increase in mean BMI in adjusted analysis, but there was weak evidence of association with the dietary covariates. Our findings suggest that a high sedentary lifestyle is a determinant of weight gain among adult women in urban India.

    Full Text Available Introduction Poor diet habits and inadequate intake of nutrients are a concern in the elderly. Nutritional education with guidance may improve the results of the treatment of vertigo. Objective Evaluate the presence of benign paroxysmal positional vertigo (BPPV associated with feeding habits. Methods Cross-sectional study with elderly people living independently. We evaluated nutritional habits through the method of dietary 24-hour recall and manipulation of Dix-Hallpike. Results Based on a sample of 487 individuals, 117 had BPPV. Among the 117 elderly patients with BPPV, 37 (31.62% had inadequate feeding. From those 370 individuals without BPPV, 97 (26.21% had inappropriate feeding. No significant association between nutritional habits and BPPV in the total population was observed (p = 0.3064. However, there was significant relation between BPPV and inadequate carbohydrate intake (p = 0.0419 and insufficient fiber intake (p = 0.03, and the diet of these subjects was rich in polyunsaturated fatty acids (p = 0.0084. Conclusion These data correlate with the dyslipidemia and hypertriglyceridemia status, making it extremely important to reduce the intake of fats and carbohydrates and increase the fiber intake to stabilize triglycerides and thus minimize harmful effects on the inner ear. Food readjustment is suggested in patients with BPPV, along with the work of a multidisciplinary team to improve the quality of the elderly.

  11. Long-term changes in the diet of Gymnogobius isaza from Lake Biwa, Japan: effects of body size and environmental prey availability.

    Directory of Open Access Journals (Sweden)

    Jonathan Carlo Briones

    Full Text Available Body size and environmental prey availability are both key factors determining feeding habits of gape-limited fish predators. However, our understanding of their interactive or relative effects is still limited. In this study, we performed quantitative dietary analysis of different body sizes of goby (Gymnogobius isaza specimens collected from Lake Biwa between 1962 and 2004. First, we report that the diet was composed mainly of zooplankton (cladocerans and copepods before the 1980s, and thereafter, shifted to zoobenthos (gammarids. This foraging shift coincided with, and thus can be linked to, known historical events in the lake at that time: decrease in zooplankton abundance with the alleviation of eutrophication, increase in fish body size resulting from fish population collapse, and increase in gammarid abundance due to reduced fish predation pressure. Supporting this view, our data analyses revealed how the long-term changes in the diet composition would be co-mediated by changes in fish body size and environmental prey availability. Specifically, while zoobenthos abundance strongly affected the fish diet composition, larger (smaller fish preferred zoobenthos (zooplankton. Furthermore, the body size effects were stronger than those of prey availability. These results provide the best long-term evidence that fish feeding habits vary over decades with its body size and prey community due to anthropogenic disturbances.

  12. A technique for long term continent gastrostomy.

    Locker, D L; Foster, J E; Craun, M L; Torma, M J

    1985-01-01

    The use of the continent gastrostomy described herein offers several advantages: 1, the elimination of an indwelling catheter; 2, prevention of soiling at skin level; 3, long term access to the normal gastrointestinal track for alimentation without fear of tube erosion; 4, little compromise to gastric volume, and 5, ease of stoma care. We recommend this operation in instances when long term tube feedings are indicated either because of damage to the central nervous system or as a palliative treatment for patients with higher obstructing gastrointestinal malignant disease. The procedure may also be useful for patients in whom esophagogastric continuity has been interrupted (surgically or traumatically) and in whom reconstruction of the gastrointestinal tract would not seem feasible within a three to six month interval.

    The long-term (14 years) psychodynamic psychotherapy and pharmacotherapy of a depressed, suicidal, self-mutilating female patient is described. Her diagnoses included Chronic Posttraumatic Stress Disorder, Borderline Personality Disorder, and Recurrent Major Depression. Treatment was punctuated with repeated hospitalizations for self-mutilation (cutting) and suicidal ideation. A major determinant for her psychopathology was sexual abuse by her father from ages 6 to 14. This resulted in feelings of guilt and rage that she repressed and acted out through self-mutilating and suicidal behavior. A prolonged negative transference gradually became ambivalent, then positive. This was associated with her internalization of the healing qualities of the therapeutic relationship. She also gained insight into the reasons for her need to punish herself. Her initial self-representation as unworthy and bad was transformed into perceiving herself as a worthwhile, loving person. This case illustrates the role of long-term treatment for a complex, life-threatening, psychiatric disorder.

    Full Text Available Dietary habits of the up side-down Mochokid catfish, Synodontis membranaceus were investigated for 24 months (April 2002-March 2004, in Jebba lake, Nigeria using frequency of occurrence, numerical, gravimetric and index of relative importance (RI methods. The fish is euryphagus and feeds more at night. RI values indicate that 10 of the 16 food items were major diet components. The main five food categories are detritus (10.64 %, Aspatharia (9.08 %, plant parts (8.85 %, seeds (8.61 % and Spirogyra (8.43 %, while the 5 less prominent food categories were gastropods (7.05 %, insect appendages (6.88 %, copepods (6.31 %, adult Povilla adusta (5.89 % and coleoptera larvae (5.36 %. The remaining six food items, dragon flies, P. adusta larvae, chironomid larvae, Daphnia, water mites and fish scales had RI values considerably under 5 %. The prominence of detritus in the diet indicated that the fish is a bottom or benthic feeder. The wide variability in food supply enables S. membranaceus to maintain its overwhelming prominence in Jebba lake, and its euryphagus habit makes it suited for pond culture. Rev. Biol. Trop. 56 (2: 931-936. Epub 2008 June 30.Los hábitos alimenticios del pez Synodontis membranaceus fueron investigados durante 24 meses (abril 2002-marzo 2004 en el lago Jebba, Nigeria; utilizando frecuencia de aparición, métodos numéricos, métodos gravimétricos y el Índice de Importancia Relativa (IR. El incremento de estómagos llenos durante la noche, en comparación con el día, indica una intensidad alta de alimentación durante la noche. El pez tiene una dieta eurífaga.

    2017-04-01

    To determine if the OOPS index is predictive of long-term hearing results after ossiculoplasty. Case series with retrospective chart review. Tertiary care otology practice. Adult and pediatric patients (3-88 years of age). Ossiculoplasty with cartilage tympanoplasty, with or without mastoidectomy. Primary outcome measures included short-term hearing results (pure-tone average air-bone gap [PTA-ABG] measured between 60 days and 1 year after surgery), long-term hearing results (PTA-ABG measured ≥5 years after surgery), and the rate of successful ABG closure to ≤20 dB. Secondary measures included the need for revision surgery, delayed tympanic membrane graft failure, worsening conductive hearing loss (after an initially satisfactory hearing result), and recurrence of cholesteatoma. There was no significant difference between adults and children for short-term hearing results (average post-op PTA-ABG was 18.9 dB vs. 19.8 dB, respectively; p = 0.544), long-term hearing results (average final PTA-ABG was 19.3 dB vs. 19.4 dB, respectively; p = 0.922), or rate of ABG closure to less than 20 dB (63.1% vs. 58.0%, p = 0.282). Spearman's rank-order correlation (ρ) identified a strong positive correlation between OOPS index score and average post-operative PTA-ABG (ρ = 0.983; p hearing outcomes in adult and pediatric patients undergoing ossiculoplasty in both the short term and the long term.

    1992-07-01

    A 27-year-old woman undergoing long-term hemodialysis developed cutaneous calcifications on her fingers. A skin biopsy specimen showed that the deposits were calcium oxalate. To our knowledge, only one previous article has reported pathologic and crystallographic studies on calcifications of the skin resulting from dialysis oxalosis. We speculate that vitamin C supplements, liberal tea consumption, an increased serum ionized calcium concentration, and the long duration of hemodialysis contributed to the production of these deposits.

    We describe a young woman with long-term untreated hyperparathyroidism with a superimposed vitamin D deficiency and an extremely decreased bone mineral density that was complicated by a vertebral fracture. Despite pretreatment with intravenous pamidronate and short-term vitamin D supplementation, severe and long-standing hypocalcaemia ('hungry bone syndrome') developed after parathyroidectomy. We discuss the consequences of hyperparathyroidism, especially the effects on bone, the complications of parathyroidectomy and the possibilities of preoperative treatment with bisphosphonates.

    We employ the Bayesian framework to define a cointegration measure aimed to represent long term relationships between time series. For visualization of these relationships we introduce a dissimilarity matrix and a map based on the sorting points into neighborhoods (SPIN) technique, which has been previously used to analyze large data sets from DNA arrays. We exemplify the technique in three data sets: US interest rates (USIR), monthly inflation rates and gross domestic product (GDP) growth rates.

    A randomised, double-blind, placebo-controlled, parallel group study assessed in healthy adults how daily consumption of the probiotic combination SYNBIO®, administered in probiotic-enriched foods or in a dietary supplement, affected bowel habits. Primary and secondary outcomes gave the overall assessment of bowel well-being, while a Psychological General Well-Being Index compiled by participants estimated the health-related quality of life as well as the gastrointestinal tolerance determined with the Gastrointestinal Symptom Rating Scale. Support Vector Machine models for classification problems were used to validate the total outcomes on bowel well-being. SYNBIO® consumption improved bowel habits of volunteers consuming the probiotic foods or capsules, while the same effects were not registered in the control groups. The recovery of probiotic bacteria from the faeces of a cohort of 100 subjects for each supplemented group showed the persistence of strains in the gastrointestinal tract.

    Dietary and exercise data are frequently recorded in clinical research, but their correlation with metabolic measures needs further evaluation. We examined the association of food and exercise habits with body size, lipid profile, and glycemia in a prospective biracial cohort. The Pathobiology of Prediabetes in A Biracial Cohort study followed initially normoglycemic offspring of parents with type 2 diabetes (T2DM) for the occurrence of incident prediabetes, defined as impaired fasting glucose (IFG) and/or impaired glucose tolerance (IGT). At enrollment, participants underwent a 75-gram OGTT, anthropometry, measurement of fasting lipids, insulin, and body fat (DEXA), and completed the Food Habits Questionnaire (FHQ), and Modifiable Activity Questionnaire (MAQ). We assessed the relationship between FHQ and MAQ scores and adiposity, cardiometabolic measures, and incident dysglycemia. Among our cohort of 338 subjects (188 black, 150 white; mean age {±SD} 45.2±10.2 years, BMI 30.3±7.2 kg/m(2)), FHQ and MAQ scores were individually correlated with BMI (r=0.14, -0.12; P=0.01, 0.03) and waist circumference (r=0.19, -0.11; P=0.004, 0.05). Diet-adjusted leisure activity (MAQ/FHQ) was significantly correlated with total body fat (r=-0.20, P=0.0007), trunk fat (r=-0.20, P=0.0006), and serum triglycerides (r=-0.17, P=0.003) and HDL cholesterol (r=0.11, P=0.04) levels. During 5.5 years of follow-up, 111 subjects (Progressors) developed prediabetes (n=101) or diabetes (n=10) and 227 remained normoglycemic (Non-progressors). Age, BMI, MAQ and MAQ/FHQ values were significant predictors of incident prediabetes/diabetes. Progressors reported similar dietary habits (FHQ score 2.57±0.49 vs. 2.57±0.53) but 30% lower physical activity (MAQ score 15.2±20.5 vs. 22.3±30.5 MET-hr/wk, P=0.015) compared with non-progressors. Among African-American and Caucasian offspring of parents with T2DM, self-reported dietary and exercise habits correlated with measures of adiposity and

    2014-01-01

    This article explores the early phase of dietary acculturation after migration. South Asian, African and Middle Eastern women (N = 21) living in Norway were interviewed about their early experiences with food in a new context. The findings pointed to abrupt changes in food habits in the first period after migration. To various degrees, women reported unfamiliarity with foods in shops, uncertainty about meal formats and food preparation and fear of eating food prohibited by their religion. Their food consumption tended to be restricted to food items perceived as familiar or safe. Our findings indicate that the first period after migration represents a specific phase in the process of dietary acculturation. Early initiatives aimed at enhancing confidence in food and familiarity with the new food culture are recommended.

    Full Text Available Melanie McGrice, Kathlene Don Paul Nutrition Plus Enterprises, Melbourne, VIC, Australia Abstract: Bariatric surgery aims to provide long-term weight loss and improvement in weight-related comorbidities. Unfortunately, some patients do not achieve predicted weight loss targets and many regain a portion of their lost weight within 2–10 years postsurgery. A review of the literature found that behavioral, dietary, psychological, physical, and medical considerations can all play a role in suboptimal long-term weight loss. Recommendations to optimize long-term weight loss include ensuring that the patient understands how the procedure works, preoperative and postoperative education sessions, tailored nutritional supplements, restraint with liquid kilojoules, pureed foods, grazing and eating out of the home, an average of 60 minutes of physical activity per day, and lifelong annual medical, psychological, and dietary assessments.Keywords: weight, bariatric, surgery

  9. Long-Term Recency in Anterograde Amnesia.

    Directory of Open Access Journals (Sweden)

    Deborah Talmi

    Full Text Available Amnesia is usually described as an impairment of a long-term memory (LTM despite an intact short-term memory (STM. The intact recency effect in amnesia had supported this view. Although dual-store models of memory have been challenged by single-store models based on interference theory, this had relatively little influence on our understanding and treatment of amnesia, perhaps because the debate has centred on experiments in the neurologically intact population. Here we tested a key prediction of single-store models for free recall in amnesia: that people with amnesia will exhibit a memory advantage for the most recent items even when all items are stored in and retrieved from LTM, an effect called long-term recency. People with amnesia and matched controls studied, and then free-recalled, word lists with a distractor task following each word, including the last (continual distractor task, CDFR. This condition was compared to an Immediate Free Recall (IFR, no distractors and a Delayed Free Recall (DFR, end-of-list distractor only condition. People with amnesia demonstrated the full long-term recency pattern: the recency effect was attenuated in DFR and returned in CDFR. The advantage of recency over midlist items in CDFR was comparable to that of controls, confirming a key prediction of single-store models. Memory deficits appeared only after the first word recalled in each list, suggesting the impairment in amnesia may emerge only as the participant's recall sequence develops, perhaps due to increased susceptibility to output interference. Our findings suggest that interference mechanisms are preserved in amnesia despite the overall impairment to LTM, and challenge strict dual-store models of memory and their dominance in explaining amnesia. We discuss the implication of our findings for rehabilitation.

    Although sexual abuse of children is recognized as a serious problem, sibling incest has received relatively little attention. A distinction has been made between power-oriented sibling incest and nurturance-oriented incest. The authors review the relevant literature and present four clinical examples. The cases illustrate the broad range of sibling incest and demonstrate its effects, including the long-term consequences for the perpetrator. Lasting difficulties in establishing and maintaining close relationships, especially sexual ones, are prominent features of each case. Without denying the occurrences of benign sex-play between siblings, the authors emphasize exploitation and abuse as pathogenic aspects of sibling incest.

    Algorithms aimed at the evaluation of critical quantities are based on models with many parameters, which values are estimated from data. The knowledge, with high accuracy, of these values and the control of their temporal evolution are important features. In this work, we focus on the latter subject, and we show a proposed pipeline for the BAM (Basic Angle Monitoring) Long Term Analysis, aimed at the study of the calibration parameters of the BAM device and of the Basic Angle variation, searching for unwanted trends, cyclic features, or other potential unexpected behaviours.

    The National Renewable Energy Laboratory started collecting wind power data from large commercial wind power plants (WPPs) in southwest Minnesota with dedicated dataloggers and communication links in the spring of 2000. Over the years, additional WPPs in other areas were added to and removed from the data collection effort. The longest data stream of actual wind plant output is more than 10 years. The resulting data have been used to analyze wind power fluctuations, frequency distribution of changes, the effects of spatial diversity, and wind power ancillary services. This report uses the multi-year wind power data to examine long-term wind power variability.

    Long-term clinical trials often include more than one active treatment group. These may be discontinued independently if found to be ineffective or possibly harmful. Certain subgroups of patients may be discovered, in the course of a clinical trial, who do not respond satisfactorily and are, therefore, excluded during the course of a trial. Yet another kind of termination comes when we have a therapeutic breakthrough or when hope has to be abandoned for demonstrating beneficial effects for one, several, or all treatments included in a trial. Examples from the authors' experience are presented, as are successful and unsuccessful techniques in managing terminations of various types.

    Carbohydrate counting (CHC) in combination with nutritional education has been used to optimize the insulin dose in patients with type 1 diabetes (T1D). The aim of this study was to test the impact of CHC and nutritional education on changes in dietary habits, body composition and body fat distribution in children with T1D treated with insulin pumps (CSII). Twenty-five children with T1D and CSII were recruited and valuated at baseline and after 18 months of follow-up. They were trained in CHC and following standard nutrition education program (based on American Diabetes Association and International Society of Pediatric and Adolescent Diabetes guidelines); clinical, biochemical and nutritional variables were measured. In the total population, body composition, body fat distribution and biochemical variables did not change, at follow-up; HbA1c was significantly reduced (8.50 ± 0.77 vs 7.92 ± 0.74 %; p nutritional education, does not affect dietary habits, body composition and body fat distribution in children with T1D treated with CSII. Moreover, the sub-group of subjects showing a significant improvement in glycometabolic control reported an increase in CHO intake and a reduction in fat and protein intake.

    Escherichia coli is one of the most frequently diagnosed causes of bovine mastitis, and is typically associated with acute, clinical mastitis. The objective of the present study was to evaluate the long term effects of intramammary infections by E. coli on milk yield and quality, especially milk coagulation. Twenty-four Israeli Holstein cows diagnosed with clinical mastitis due to intramammary infection by E. coli were used in this study. Mean lactation number, days in milk (DIM) and daily milk yield (DMY) at the time of infection was 3.3 ± 1.3, 131.7 days ± 78.6 and 45.7 L ± 8.4, respectively. DMY, milk constituents, somatic cells count (SCC), differential leukocytes count and coagulation parameters were subsequently assessed. Two patterns of inflammation were identified: 'short inflammation', characterized by 15% decrease in DMY and >30 days to reach a new maximum DMY (n = 19). The estimated mean loss of marketable milk during the study was 200 L/cow for 'short inflammation' cases, and 1,500 L/cow for 'long inflammation' ones. Significant differences between 'short' and 'long inflammation' effects were found in almost all parameters studied. Long-term detrimental effects on milk quality were found regardless of clinical or bacteriological cure of affected glands.

    Adipose tissue engineered models are needed to enhance our understanding of disease mechanisms and for soft tissue regenerative strategies. Perfusion systems generate more physiologically relevant and sustainable adipose tissue models, however adipocytes have unique properties that make culturing them in a perfusion environment challenging. In this paper we describe the methods involved in the development of two perfusion culture systems (2D and 3D) to test their applicability for long term in vitro adipogenic cultures. It was hypothesized that a silk protein biomaterial scaffold would provide a 3D framework, in combination with perfusion flow, to generate a more physiologically relevant sustainable adipose tissue engineered model than 2D cell culture. Consistent with other studies evaluating 2D and 3D culture systems for adipogenesis we found that both systems successfully model adipogenesis, however 3D culture systems were more robust, providing the mechanical structure required to contain the large, fragile adipocytes that were lost in 2D perfused culture systems. 3D perfusion also stimulated greater lipogenesis and lipolysis and resulted in decreased secretion of LDH compared to 2D perfusion. Regardless of culture configuration (2D or 3D) greater glycerol was secreted with the increased nutritional supply provided by perfusion of fresh media. These results are promising for adipose tissue engineering applications including long term cultures for studying disease mechanisms and regenerative approaches, where both acute (days to weeks) and chronic (weeks to months) cultivation are critical for useful insight.

    The radioactive pollution of the environment results from the atmospheric nuclear weapons testing (during the mid-years of twentieth century), from the development of the civilian nuclear industry and from accidents such as Chernobyl. Assessing the resulting radiation that humans might receive requires a good understanding of the long-term behaviour of radionuclides in the environment. This document reports on a joint European effort to advance this understanding, 3 multinational projects have been coordinated: PEACE, EPORA and LANDSCAPE. This report proposes an overview of the results obtained and they are presented in 6 different themes: (i) redistribution in the soil-plant system, (ii) modelling, (iii) countermeasures, (iv) runoff (v) spatial variations, and (vi) dose assessment. The long term behaviour of the radionuclides {sup 137}Cs, {sup 90}Sr and {sup 239-240}Pu is studied through various approaches, these approaches range from in-situ experiments designed to exploit past contamination events to laboratory simulations. A broad scope of different ecosystems ranging from arctic and boreal regions down to mediterranean ones has been considered. (A.C.)

    Long term tests of PSI membranes based on radiation-grafted FEP and ETFE films were carried out and FEP-based membranes were evaluated by monitoring the in-situ membrane area resistance measured by a current pulse method. By modifying our irradiation procedure and using the double crosslinking concept we obtain reproducible membrane cell lifetimes (in term of in-situ membrane resistance) of greater than 5000 hours at 60-65{sup o}C. Preliminary tests at 80-85{sup o}C with lifetimes of greater than 2500 demonstrate the potential long term stability of PSI proton exchange membranes based on FEP over the whole operating temperature range of low-temperature polymer electrolyte fuel cells. Radiation grafted PSI membranes based on ETFE have better mechanical properties than those of the FEP membranes. Mechanical properties are particularly important in large area cells and fuel cell stacks. ETFE membranes have been tested successfully for approximately 1000 h in a 2-cell stack (100 cm{sup 2} active area each cell). (author) 4 figs., 4 refs.

    As the amount of halogens in the stratosphere is slowly declining and the ozone layer slowly recovers it is of interest to see how the meteorological conditions in the vortex develop over the long term since such changes might alter the foreseen ozone recovery. In conjunction with the publication of the WMO Antarctic and Arctic Ozone Bulletins, WMO has acquired the ERA Interim global reanalysis data set for several meteorological parameters. This data set goes from 1979 - present. These long time series of data can be used for several useful studies of the long term development of the polar vortices. Several "environmental indicators" for vortex change have been calculated, and a climatology, as well as trends, for these parameters will be presented. These indicators can act as yardsticks and will be useful for understanding past and future changes in the polar vortices and how these changes affect polar ozone depletion. Examples of indicators are: vortex mean temperature, vortex minimum temperature, vortex mean PV, vortex "importance" (PV*area), vortex break-up time, mean and maximum wind speed. Data for both the north and south polar vortices have been analysed at several isentropic levels from 350 to 850 K. A possible link between changes in PV and sudden stratospheric warmings will be investigated, and the results presented. The unusual meteorological conditions of the 2015 south polar vortex and the 2010/11 and 2015/16 north polar vortices will be compared to other recent years.

    The benefit of climate Long Term Memory (LTM) for long term prediction is assessed using data from a millennium control simulation with the atmosphere ocean general circulation model ECHAM5/MPIOM. The forecast skills are evaluated for surface temperature time series at individual grid points. LTM is characterised by the Hurst exponent in the power-law scaling of the fluctuation function which is determined by detrended fluctuation analysis (DFA). LTM with a Hurst exponent close to 0.9 occurs mainly in high latitude oceans, which are also characterized by high potential predictability. Climate predictability is diagnosed in terms of potentially predictable variance fractions. Explicit prediction experiments for various time steps are conducted on a grid point basis using an auto-correlation (AR1) predictor: in regions with LTM, prediction skills are beyond that expected from red noise persistence; exceptions occur in some areas in the southern oceans and over the northern hemisphere continents. Extending the predictability analysis to the fully forced simulation shows large improvement in prediction skills.

    Caspian Sea level (CSL) has undergone substantial fluctuations during the past several hundred years. The causes over the entire historical period are uncertain, but we investigate here large changes seen in the past several decades. We use climate model-predicted precipitation (P), evaporation (E), and observed river runoff (R) to reconstruct long-term CSL changes for 1979-2015 and show that PER (P-E + R) flux predictions agree very well with observed CSL changes. The observed rapid CSL increase (about 12.74 cm/yr) and significant drop ( -6.72 cm/yr) during the periods 1979-1995 and 1996-2015 are well accounted for by integrated PER flux predictions of +12.38 and -6.79 cm/yr, respectively. We show that increased evaporation rates over the Caspian Sea play a dominant role in reversing the increasing trend in CSL during the past 37 years. The current long-term decline in CSL is expected to continue into the foreseeable future, under global warming scenarios.

    Full Text Available Patients infected with HIV are best categorized along a continuum from rapid progressors to HIV long-term nonprogressors. Long-term nonprogressors (LTNPs are those in which AIDS develop many years after being infected with HIV, often beyond the 10-year mark, and represent 15–20% of the HIV infected patients. Many of these patients are able to control their infection and maintain undetectable viral loads for long periods of time without antiretroviral therapy. After a comprehensive literature search, we found extensive data related to HIV LTNPs in the adult population; however, very limited data was available related to LTNPs within the pediatric population. We present a case of pediatric HIV LTNPs, perinatally infected patient with undetectable viral loads, despite never receiving ART. Although there are not many instances of LTNPs among children, this child may be one, though she had intermittent viremia. She has continued to manifest serologic evidence of infection, with yearly ELISA and western blot positive tests. Based on the viral fitness studies that were performed, this case exemplifies an adolescent LTNP.

    Adaptation is an automatic neural mechanism supporting the optimization of visual processing on the basis of previous experiences. While the short-term effects of adaptation on behaviour and physiology have been studied extensively, perceptual long-term changes associated with adaptation are still poorly understood. Here, we show that the integration of adaptation-dependent long-term shifts in neural function is facilitated by sleep. Perceptual shifts induced by adaptation to a distorted image of a famous person were larger in a group of participants who had slept (experiment 1) or merely napped for 90 min (experiment 2) during the interval between adaptation and test compared with controls who stayed awake. Participants' individual rapid eye movement sleep duration predicted the size of post-sleep behavioural adaptation effects. Our data suggest that sleep prevented decay of adaptation in a way that is qualitatively different from the effects of reduced visual interference known as 'storage'. In the light of the well-established link between sleep and memory consolidation, our findings link the perceptual mechanisms of sensory adaptation--which are usually not considered to play a relevant role in mnemonic processes--with learning and memory, and at the same time reveal a new function of sleep in cognition.

  10. Institutionalization and Organizational Long-term Success

    Full Text Available Institutionalization processes have an ambivalent effect on organizational long-term success. Even though they foster organizational stability and permanence, they also bring about rigidity and resistance to change. As a result, successful organizations are likely to lose their competitive advantage over time. The paper addresses this issue through the investigation of the institutionalization processes of two long-lived companies: General Electric, a firm that has been a long-term success and its rival, Westinghouse, which was broken up after eleven decades of existence. The longitudinal, multilevel analysis of firms and industry has identified two different modes of organizational institutionalization. The reactive mode gives rise to rigidity and change resistance, much like institutional theory predicts; the proactive mode, on the other hand, neutralizes those negative effects of institutionalization processes. In the reactive mode, structure predominates. In the proactive mode, agency plays a major role in organizational institutionalization, and in managing the organization’s relations with the environment, clearly contributing to environmental institutionalization.

    The definition and determinants of successful aging is still controversial. Although dietary habits have long been associated with aging, eating habits and behaviors have rarely been included in various proposed indices of successful aging. The aim of this work was to evaluate determinants of successful aging together with assessment of dietary habits in relation to healthcare facility use among elders living in the Mediterranean basin. During 2005-2011, 2663 elderly (aged 65-100 years) individuals from 21 Mediterranean islands and rural Mani region (Peloponnesus) were voluntarily enrolled in the study. A successful aging index ranging from a score of 0 to a score of 10 was constructed using 10 attributes, i.e., education, financial status, physical activity, body mass index, depression, participation in social activities with friends and family, number of yearly excursions, number of cardiovascular disease risk factors and adherence to the Mediterranean diet. The applied factor analysis on the components of the index extracted three main components for successful aging: psychosocial-economic, bioclinical and lifestyle; confirming the multiple dimensions of aging. After adjusting for confounders, a 1/10-unit increase in the successful aging index was associated with 0.8 less annual visits to healthcare centers (95% CI -1.3 to-0.2). Stratified analysis by gender revealed heterogeneity of factors predicting successful aging. These findings suggest that successful aging is a multidimensional and complex concept that exhibits gender heterogeneity. Annual use of health care services by the elders was found to be related to level of successful aging.

    A study on the long-term efficacy of femoral-popliteal angioplasty was carried out on 185 angioplasty cases over a 5 year follow-up period. A classification of data according to the type of lesion treated, revealed that results were favorable in case of stenosis (87%), short obstruction (70%) and long obstruction (35%). A special study of the outcome of treatments for stage IV arteritis was carried out. After comparing results with those obtained by other teams, the authors list the complications encountered, hematomas, and thromboses, and show their current tendency for regression. Lastly, the authors stress the advantages of angioscopy, which permits to identify the nature of the treated lesions and to predict possible complications, which are usually underrated by angiography.

    Severe staff shortages in long-term care (LTC) make it difficult to meet the demands of the growing aging population. Further, technology-savvy Baby Boomers are expected to reshape the current institutional environments toward gaining more freedom and control in their care and lives. Voices from business, academia, research, advocacy organizations, and government bodies suggest that innovative technological approaches are the linchpin that may prepare society to cope with these projected demands. In this article, we review the current state of aging-related technology, identify potential areas for efficacy testing on improving the quality of life of LTC residents in future research, and discuss barriers to implementation of LTC technology. Finally, we present a vision of future technology use that could transform current care practices.

    In exploring the emotional climate of long-term marriages, this study used an observational coding system to identify specific emotional behaviors expressed by middle-aged and older spouses during discussions of a marital problem. One hundred and fifty-six couples differing in age and marital satisfaction were studied. Emotional behaviors expressed by couples differed as a function of age, gender, and marital satisfaction. In older couples, the resolution of conflict was less emotionally negative and more affectionate than in middle-aged marriages. Differences between husbands and wives and between happy and unhappy marriages were also found. Wives were more affectively negative than husbands, whereas husbands were more defensive than wives, and unhappy marriages involved greater exchange of negative affect than happy marriages.

    Unlike Trojans, horseshoe coorbitals are not generally considered to be long-term stable (Dermott and Murray, 1981; Murray and Dermott, 1999). As the lifetime of Earth's and Venus's horseshoe coorbitals is expected to be about a Gyr, we investigated the possible contribution of late-escaping inner planet coorbitals to the lunar Late Heavy Bombardment. Contrary to analytical estimates, we do not find many horseshoe objects escaping after first 100 Myr. In order to understand this behaviour, we ran a second set of simulations featuring idealized planets on circular orbits with a range of masses. We find that horseshoe coorbitals are generally long lived (and potentially stable) for systems with primary-to-secondary mass ratios larger than about 1200. This is consistent with results of Laughlin and Chambers (2002) for equal-mass pairs or coorbital planets and the instability of Jupiter's horseshoe companions (Stacey and Connors, 2008). Horseshoe orbits at smaller mass ratios are unstable because they must approa...

    We present the case of a female patient suffering a peritonitis episode after subtotal gastrectomy due to gastric neoplasm in relation to lesser curvature necrosis extending to the anterior esophageal wall. This an uncommon andsevere complication that made mandatory further aggressive surgery: transection of the abdominal esophagus, transection of the gastric stump, and cervical esophagostomy with creation of a jejunostomy with a needle catheter for feeding. This digestive tube access technique is generally used during major abdominal post-surgery until oral intake is reestablished. Our patient has been 187 days with this therapy since reconstruction of the GI tract was ruled out due to tumoral infiltration of the colon and tumor recurrence at the gastrohepatic omentum. To date, there has been no complication from permanence and/or long-term use of this technique.

    Using the Lomb-Scargle periodogram we analyzed two sunspot series: the one over the past 11000 years at the 10-year interval based upon the survey data of 14C concentration in tree-rings, reconstructed by Solanki et al.; and the sunspot number over the past 7000 years, derived from geomagnetic variations by Usoskin et al. We found the periods and quasi-periods in solar activity, such as about 225, 352, 441, 522 and 561 a, and near 1000 and 2000 a. An approach of wavelet transform was applied to check the two sunspot time series, with emphasis on investigating time-varying characteristics in the long-term fluctuations of solar activity. The results show that the lengths and amplitudes of the periods have changed with time, and large variations have taken place during some periods.

    Full Text Available We explore the social psychological processes through which fan-based experiences become situated in fans' larger life narratives. Drawing on original survey data with long-term U.S. soap opera fans, we examine how the psychological mechanism of autobiographical reasoning functions in fans' construction of self-narratives over time. The case study presented here is a subset of a larger investigation into the age-related structure of fans' activities, identities, and interpretive capacities. Situated at the intersections of gerontological (life span/life course theory and contemporary fan studies, our project mines relatively uninvestigated theoretical terrain. We conclude with a brief discussion of implications for future fan studies.

    1988-09-01

    In 20 patients with 21 Brodie's abscesses, a long-term review revealed that 13 occurred in the second decade of life. All had local symptoms for six weeks or more. The tibia was involved in 11 cases and seven of these were in the proximal metaphysis. The erythrocyte sedimentation rate (ESR) was elevated in only six cases. When the ESR was more than 40 mm per hour, recurrence was more likely. Staphylococcus aureus was cultured from 11 abscesses. Curettage and antibiotics for six weeks were adequate for treatment in most cases. However, lesions larger than 3 cm in diameter should be grafted, and patients with an elevated ESR require more aggressive decompression and prolonged antibiotic therapy. Lesions within the neck of the femur pose particular anatomic problems and should not be approached laterally. All cases were followed to full bone maturity. No significant leg length inequality was clinically or roentgenologically apparent. If an abscess was juxtaphyseal, deformity of the epiphysis could develop.

    1998-01-01

    The zonation of Typha populations in an experimental pond in Michigan was re-examined 15 years after the original sampling to gain insight into the long-term dynamics. Current distributions of Typha populations were also examined in additional experimental ponds at the site that have been maintained for 23 years. The zonation between T. latifolia and T. angustifolia in the previously studied pond 15 years after the initial sampling revealed that the density and distribution of shoots had not changed significantly. Thus, it appears that previously reported results (based on 7- year old populations) have remained consistent over time. Additional insight into the interaction between these two taxa was sought by comparing mixed and monoculture stands in five experimental ponds that have remained undisturbed for their 23-year history. The maximum depth of T. latifolia, the shallow- water species, was not significantly reduced when growing in the presence of the more flood tolerant T. angustifolia. In contrast, the minimum depth of T. angustifolia was reduced from 0 to 37 cm when in the presence of T. latifolia. When total populations were compared between monoculture and mixed stands, the average density of T. angustifolia shoots was 59.4 percent lower in mixed stands while the density of T. latifolia was 32 percent lower, with T. angustifolia most affected at shallow depths (reduced by 92 percent) and T. latifolia most affected at the deepest depths (reduced by 60 percent). These long-term observations indicate that competitive displacement between Typha taxa has remained stable over time.

    Full Text Available Abstract Background This study was undertaken to assess long-term changes in tinnitus severity exhibited by patients who completed a comprehensive tinnitus management program; to identify factors that contributed to changes in tinnitus severity within this population; to contribute to the development and refinement of effective assessment and management procedures for tinnitus. Methods Detailed questionnaires were mailed to 300 consecutive patients prior to their initial appointment at the Oregon Health & Science University Tinnitus Clinic. All patients were then evaluated and treated within a comprehensive tinnitus management program. Follow-up questionnaires were mailed to the same 300 patients 6 to 36 months after their initial tinnitus clinic appointment. Results One hundred ninety patients (133 males, 57 females; mean age 57 years returned follow-up questionnaires 6 to 36 months (mean = 22 months after their initial tinnitus clinic appointment. This group of patients exhibited significant long-term reductions in self-rated tinnitus loudness, Tinnitus Severity Index scores, tinnitus-related anxiety and prevalence of current depression. Patients who improved their sleep patterns or Beck Depression Inventory scores exhibited greater reductions of tinnitus severity scores than patients who continued to experience insomnia and depression at follow-up. Conclusions Individualized tinnitus management programs that were designed for each patient contributed to overall reductions in tinnitus severity exhibited on follow-up questionnaires. Identification and treatment of patients experiencing anxiety, insomnia or depression are vital components of an effective tinnitus management program. Utilization of acoustic therapy also contributed to improvements exhibited by these patients.

    Full Text Available Amin F EllakwaMenoufiya University, Shibin el Kom, Al-Menoufiya, EgyptBackground: Rhegmatogenous retinal detachment is a commonly encountered retinal problem where rapid treatment can prevent irreversible vision loss. Pneumatic retinopexy (PR is a simple, minimally invasive procedure for retinal reattachment.Purpose: This study aimed to assess the long-term anatomical and functional outcome of pneumatic retinopexy in primary rhegmatogenous retinal detachment.Patients and methods: A prospective interventional study was performed. Subjects with rhegmatogenous retinal detachment who underwent pneumatic retinopexy from May 2006 to May 2007 at Menoufiya University Hospital were included in this study with at least 3 years follow-up.Results: A total of 40 cases were included in the study. The mean age of patients was 44.25 ± 10.85 years. Reattachment of the retina was achieved in 100% of cases. In 75% of cases, the primary intervention was successful. However, the retina redetached in 20% of these during the first 6 months, requiring reinjection or another procedure. Three years after the first intervention, follow-up measurement of the mean visual acuity of the eyes without reoperation was 0.40 ± 0.21 while the mean visual acuity of the eyes which needed additional operations was 0.22 ± 0.13.Conclusion: Sixty percent of the cases obtained long-term retinal reattachment with a single operation success (SOS, with good visual recovery and less morbidity than other more invasive procedures like scleral buckling or pars plana vitrectomy, translating to higher productivity for the patient. This procedure, being quicker than the alternatives, also saves the surgeon's time, making PR a good choice for managing primary rhegmatogenous retinal detachment in developing countries.Keywords: pneumatic, retinopexy, rhegmatogenous, retinal detachment

    Experiments were conducted with 270 Abore Acre male broilers to study the influence of dietary chlortetracycline (CTC) on the bursal, thymus and spleen weight index and T, B cell proliferation and antibody responses of broilers. Results show that 50mg/kg CTC had no significant inhibitory effect on thymus and spleen weight index, and T, B cell proliferation of broilers at 21 days old. 150mg/kg CTC had significant inhibitory effect on bursal, thymus and spleen, and T, B cell proliferation (P<0.05). Dietary CTC had a direct inhibitory effect on lymphocyte proliferation in vitro. 50mg/kg and 150mg/kg CTC had a significant inhibitory effect on the antibody responses to BSA (P<0.01). Results demonstrated that subtherapeutic and long term CTC had significant inhibitory effects on immune organs and antibody response. The immunosuppressant effect became higher when the level of CTC increased. 150mg/kg CTC increased the growth rate of broilers significantly.

    The different dietary habits and nutritional status of Spanish school children have been analyzed. Nutrition affects health throughout the life cycle, and it is best to begin to prevent harm early on. Habits are formed early in life, and habits are a major determinant of food choice in later life. Two trends in particular are worthy of mention in this regard: the progressive globalisation of the food supply and the increase of food intake such as snacks, soft drinks and fast food, wich tipica...

  7. Long-term potentiation and long-term depression: a clinical perspective

    2011-01-01

    Full Text Available Long-term potentiation and long-term depression are enduring changes in synaptic strength, induced by specific patterns of synaptic activity, that have received much attention as cellular models of information storage in the central nervous system. Work in a number of brain regions, from the spinal cord to the cerebral cortex, and in many animal species, ranging from invertebrates to humans, has demonstrated a reliable capacity for chemical synapses to undergo lasting changes in efficacy in response to a variety of induction protocols. In addition to their physiological relevance, long-term potentiation and depression may have important clinical applications. A growing insight into the molecular mechanisms underlying these processes, and technological advances in non-invasive manipulation of brain activity, now puts us at the threshold of harnessing long-term potentiation and depression and other forms of synaptic, cellular and circuit plasticity to manipulate synaptic strength in the human nervous system. Drugs may be used to erase or treat pathological synaptic states and non-invasive stimulation devices may be used to artificially induce synaptic plasticity to ameliorate conditions arising from disrupted synaptic drive. These approaches hold promise for the treatment of a variety of neurological conditions, including neuropathic pain, epilepsy, depression, amblyopia, tinnitus and stroke.

    Full Text Available Abstract Background Childhood obesity is multi-factorial and determined to a large extent by dietary habits, physical activity and sedentary behaviours. Previous research has shown that school-based programmes are effective but that their effectiveness can be improved by including a parental component. At present, there is a lack of effective parental support programmes for improvement of diet and physical activity and prevention of obesity in children. Methods/Design This paper describes the rationale and design of a parental support programme to promote healthy dietary habits and physical activity in six-year-old children starting school. The study is performed in close collaboration with the school health care and is designed as a cluster-randomised controlled trial with a mixed methods approach. In total, 14 pre-school classes are included from a municipality in Stockholm county where there is large variation in socio-economic status between the families. The school classes are randomised to intervention (n = 7 and control (n = 7 groups including a total of 242 children. The intervention is based on social cognitive theory and consists of three main components: 1 a health information brochure; 2 two motivational interviewing sessions with the parents; and 3 teacher-led classroom activities with the children. The primary outcomes are physical activity in the children measured objectively by accelerometry, children's dietary and physical activity habits measured with a parent-proxy questionnaire and parents' self-efficacy measured by a questionnaire. Secondary outcomes are height, weight and waist circumference in the children. The duration of the intervention is six months and includes baseline, post intervention and six months follow-up measurements. Linear and logistic regression models will be used to analyse differences between intervention and control groups in the outcome variables. Mediator and moderator analysis will be performed

    were instructed to maintain the fiber-rich diet for four months in order to determine if the efficacy continued over time and the degree of adherence to its use. The association between adherence and efficacy was investigated by the Fisher's exact test. RESULTS: Although nine individuals abandoned the study, 50 returned. From these, 32 sustained normal bowel movements and 18 had recurrence of the constipation. In the first group, 16 continued consuming the same amount of fiber, four increased, nine reduced and three stopped taking it. In the group with recurrence, three maintained the same amount of fiber, one increased, three reduced and eleven stopped taking it. There was a significant statistical association between adherence and efficacy (p=0.008. CONCLUSION: The long-term efficacy of dietary fiber for the treatment of constipation was moderate (64% and treatment drop-out rate was high (52%. These results suggest the need of new strategies that promote greater fidelity to fiber therapy, thereby improving the efficacy of constipation treatment.

  15. LONG-TERM MONITORING SENSOR NETWORK

    Energy Technology Data Exchange (ETDEWEB)

    2003-10-16

    Long-term monitoring (LTM) associated with subsurface contamination sites is a key element of Long Term Stewardship and Legacy Management across the Department of Energy (DOE) complex. However, both within the DOE and elsewhere, LTM is an expensive endeavor, often exceeding the costs of the remediation phase of a clean-up project. The primary contributors to LTM costs are associated with labor. Sample collection, storage, preparation, analysis, and reporting can add a significant financial burden to project expense when extended over many years. Development of unattended, in situ monitoring networks capable of providing quantitative data satisfactory to regulatory concerns has the potential to significantly reduce LTM costs. But survival and dependable operation in a difficult environment is a common obstacle to widespread use across the DOE complex or elsewhere. Deploying almost any sensor in the subsurface for extended periods of time will expose it to chemical and microbial degradation. Over the time-scales required for in situ LTM, even the most advanced sensor systems may be rendered useless. Frequent replacement or servicing (cleaning) of sensors is expensive and labor intensive, offsetting most, if not all, of the cost savings realized with unattended, in situ sensors. To enable facile, remote monitoring of contaminants and other subsurface parameters over prolonged periods, Applied Research Associates, Inc has been working to develop an advanced LTM sensor network consisting of three key elements: (1) an anti-fouling sensor chamber that can accommodate a variety of chemical and physical measurement devices based on electrochemical, optical and other techniques; (2) two rapid, cost effective, and gentle means of emplacing sensor packages either at precise locations directly in the subsurface or in pre-existing monitoring wells; and (3) a web browser-based data acquisition and control system (WebDACS) utilizing field-networked microprocessor-controlled smart

    This study was conducted to determine the impact of dietary acculturation on the health status of newly arrived international students at Virginia Tech in Fall 2010. Thirty-five international students, 18-36 years of age, completed the study. Data were collected at 3 different time periods (V1, V2, and V3) approximately 6 weeks apart. A food frequency- and dietary pattern-related questionnaire was administered and numerically coded responses were analyzed. Twenty-four-hour dietary recall data were also collected at V1, V2, and V3. Body weight, fasting blood glucose level, and blood pressure of study participants were also determined at each time period. Total sample population (TSP) had a significant increase in mean weight of 2.79 lb from visit 1 (V1) to visit 3 (V3) (p = .0082). Ten participants gained an average of 9.0 lb (participants who gained weight; n = 10). There was also an increase in the frequency of consumption of high-calorie American food items from V1 to V3. However, there were no significant changes in mean systolic blood pressure and mean fasting blood glucose was significantly lower at V3 than at V1. There was a gradual shift in the dietary patterns of international students towards the American diet. Dietary acculturation led to weight gain among some of the students, which may potentially have a negative impact on their health status if continued for longer time periods.

    Full Text Available INTRODUCTION: Neuroparacoccidioidomycosis (NPCM is a term used to describe the invasion of the central nervous system by the pathogenic fungus Paracoccidioides brasiliensis. NPCM has been described sporadically in some case reports and small case series, with little or no focus on treatment outcome and long-term follow-up. METHODS: All patients with NPCM from January 1991 to December 2006 were analyzed and were followed until December 2009. RESULTS: Fourteen (3.8% cases of NPCM were identified out of 367 patients with paracoccidioidomycosis (PCM. A combination of oral fluconazole and sulfamethoxazole/trimethoprim (SMZ/TMP was the regimen of choice, with no documented death due to Paracoccidioides brasiliensis infection. Residual neurological deficits were observed in 8 patients. Residual calcification was a common finding in neuroimaging follow-up. CONCLUSIONS: All the patients in this study responded positively to the association of oral fluconazole and sulfamethoxazole/trimethoprim, a regimen that should be considered a treatment option in cases of NPCM. Neurological sequela was a relatively common finding. For proper management of these patients, anticonvulsant treatment and physical therapy support were also needed.

    2014-01-01

    Long-term soft denture lining (LTSDL) materials are used to alleviate the trauma associated with wearing complete dentures. Despite their established clinical efficacy, the use of LTSDLs has been limited due to the unfavorable effects of the oral environment on some of their mechanical and performance characteristics. The unresolved issue of LTSDL colonization by Candida albicans is particularly problematic. Silicone-based LTSDL (SLTSDL) materials, which are characterized by more stable hardness, sorption and solubility than acrylic-based LTSDLs (ALTSDLs), are currently the most commonly used LTSDLs. However, SLTSDLs are more prone to debonding from the denture base. Moreover, due to their limitations, the available methods for determining bond strength do not fully reflect the actual stability of these materials under clinical conditions. SLTSDL materials exhibit favorable viscoelastic properties compared with ALTSDLs. Furthermore, all of the lining materials exhibit an aging solution-specific tendency toward discoloration, and the available cleansers are not fully effective and can alter the mechanical properties of LTSDLs. Future studies are needed to improve the microbiological resistance of LTSDLs, as well as some of their performance characteristics. PMID:28788163

    One of the unique and scientifically most challenging aspects of nuclear waste isolation is the extrapolation of short-term laboratory data (hours to years) to the long time periods (10{sup 3}-10{sup 5} years) required by regulatory agencies for performance assessment. The direct validation of these extrapolations is not possible, but methods must be developed to demonstrate compliance with government regulations and to satisfy the lay public that there is a demonstrable and reasonable basis for accepting the long-term extrapolations. Natural systems (e.g., {open_quotes}natural analogues{close_quotes}) provide perhaps the only means of partial {open_quotes}validation,{close_quotes} as well as data that may be used directly in the models that are used in the extrapolation. Natural systems provide data on very large spatial (nm to km) and temporal (10{sup 3}-10{sup 8} years) scales and in highly complex terranes in which unknown synergisms may affect radionuclide migration. This paper reviews the application (and most importantly, the limitations) of data from natural analogue systems to the {open_quotes}validation{close_quotes} of performance assessments.

    This document describes the testing and facility requirements to support the Yucca Mountain Project long-term corrosion testing needs. The purpose of this document is to describe a corrosion testing program that will (a) reduce model uncertainty and variability, (b) reduce the reliance upon overly conservative assumptions, and (c) improve model defensibility. Test matrices were developed for 17 topical areas (tasks): each matrix corresponds to a specific test activity that is a subset of the total work performed in a task. A future document will identify which of these activities are considered to be performance confirmation activities. Detailed matrices are provided for FY08, FY09 and FY10 and rough order estimates are provided for FY11-17. Criteria for the selection of appropriate test facilities were developed through a meeting of Lead Lab and DOE personnel on October 16-17, 2007. These criteria were applied to the testing activities and recommendations were made for the facility types appropriate to carry out each activity. The facility requirements for each activity were assessed and activities were identified that can not be performed with currently available facilities. Based on this assessment, a total of approximately 10,000 square feet of facility space is recommended to meet all future testing needs, given that all testing is consolidated to a single location. This report is a revision to SAND2007-7027 to address DOE comments and add a series of tests to address NWTRB recommendations.

    Full Text Available This is an investigated research article on resource block scheduling of Long Term Evolution (LTE. LTE is one of the evolutions of the Universal Mobile Telecommunication System (UMTS. It provides internet access to mobile users through smart phone, laptop and other android devices. LTE offers a high speed data and multimedia services. It supports data rates up to 100 Mbps in the downlink and 50 Mbps in the uplink transmission. Our research investigation was aim to the downlink scheduling. We have considered The Best CQI scheduling algorithm and the Round Robin scheduling algorithm. The implementation, analysis and comparison of these scheduling algorithms have been performed through MATLAB simulator. We have analyzed the impact of the scheduling schemes on the throughput and the fairness of both scheduling schemes. Here we have proposed a new scheduling algorithm that achieves a compromise between the throughput and the fairness. Orthogonal Frequency Division Multiplexing (OFDM has been adopted as the downlink transmission scheme. We have considered the impact of the channel delay on the throughput. In addition, MIMO transceiver systems have been implemented to increase the throughput

    We study the long-term evolution (LTE) of plasma wakefields over multiple plasma-electron periods and few plasma-ion periods, much less than a recombination time. The evolution and relaxation of such a wakefield-perturbed plasma over these timescales has important implications for the upper limits of repetition-rates in plasma colliders. Intense fields in relativistic lasers (or intense beams) create plasma wakefields (modes around {\\omega}pe) by transferring energy to the plasma electrons. Charged-particle beams in the right phase may be accelerated with acceleration/focusing gradients of tens of GeV/m. However, wakefields leave behind a plasma not in equilibrium, with a relaxation time of multiple plasma-electron periods. Ion motion over ion timescales, caused by energy transfer from the driven plasma-electrons to the plasma-ions can create interesting plasma states. Eventually during LTE, the dynamics of plasma de-coheres (multiple modes through instability driven mixing), thermalizing into random motion (...

    Full Text Available Mandibular distraction osteogenesis has become a popular surgical modality due to its many advantages over conventional orthognathic surgical procedures. However, in spite of the technique having been used for over 15 years, no concrete long term results are available regarding the stability of results. We discuss the various studies which have reported either in favour or against the stablility of results after distraction. We report a series of 6 cases (3 unilateral and 3 bilateral distraction where distraction was carried out before puberty and followed them up to seven years after removal of distractors. This case series shows that results achieved by distraction osteogenesis are unstable or best unpredictable with respect to producing a permanent size increase in the mandible. The role of the distraction osteogenesis in overcoming the pterygomassetric sling is questionable. We suggest a multicenter study with adequate patient numbers treated with a similar protocol and documented after growth cessation to have meaningful conclusions on the debate of distraction osteogenesis versus orthognathic surgery.

    The negatively charged nitrogen vacancy (NV−) center in diamond is the focus of widespread attention for applications ranging from quantum information processing to nanoscale metrology. Although most work so far has focused on the NV− optical and spin properties, control of the charge state promises complementary opportunities. One intriguing possibility is the long-term storage of information, a notion we hereby introduce using NV-rich, type 1b diamond. As a proof of principle, we use multicolor optical microscopy to read, write, and reset arbitrary data sets with two-dimensional (2D) binary bit density comparable to present digital-video-disk (DVD) technology. Leveraging on the singular dynamics of NV− ionization, we encode information on different planes of the diamond crystal with no cross-talk, hence extending the storage capacity to three dimensions. Furthermore, we correlate the center’s charge state and the nuclear spin polarization of the nitrogen host and show that the latter is robust to a cycle of NV− ionization and recharge. In combination with super-resolution microscopy techniques, these observations provide a route toward subdiffraction NV charge control, a regime where the storage capacity could exceed present technologies.

    Full Text Available Oral ulcers is a very common disorder of the oral mucosa. Patients with signs or symptoms of oral ulcers are sometimes referred to gastroenterology clinics, however, in most instances the ulcers does not reflect gastrointestinal disease, some with a chronic non- healing ulcer are advised biopsy. Indeed, a spectrum of disorders can give rise to oral mucosal ulcers ranging from minor local trauma to significant local disease such as malignancy or systemic illness. Lesions of the tongue have a broad differential diagnosis ranging from benign idiopathic processes to infections, cancers, and infiltrative disorders. This article will focus on common ulcerative disorders of the tongue in aspects of their clinical features and differential diagnosis, two case reports with the diagnosis and conservative management for long-term chronic ulcers. The two cases which are reported in this article had a differential diagnosis of Squamous cell carcinoma of the tongue. The clinical picture was craterlike lesion, having a velvety-red base and a rolled, indurated border and most important painless in both cases. Removal of the irritant which was the tooth, rehabilitation of the oral mucosa by lubrication with Cocus Nucifera resulted in the healing of the ulcers. Functional components of Cocus Nucifera are Squaline, tocopherol, phytosterols and other sterols which are all plant steroids.

The unresolved issue of LTSDL colonization by Candida albicans is particularly problematic. Silicone-based LTSDL (SLTSDL materials, which are characterized by more stable hardness, sorption and solubility than acrylic-based LTSDLs (ALTSDLs, are currently the most commonly used LTSDLs. However, SLTSDLs are more prone to debonding from the denture base. Moreover, due to their limitations, the available methods for determining bond strength do not fully reflect the actual stability of these materials under clinical conditions. SLTSDL materials exhibit favorable viscoelastic properties compared with ALTSDLs. Furthermore, all of the lining materials exhibit an aging solution-specific tendency toward discoloration, and the available cleansers are not fully effective and can alter the mechanical properties of LTSDLs. Future studies are needed to improve the microbiological resistance of LTSDLs, as well as some of their performance characteristics.

    In this paper we describe the services that are offered by CERN for Long Term preservation of High Energy Physics (HEP) data, with the Large Hadron Collider (LHC) as a key use case. Data preservation is a strategic goal for European High Energy Physics (HEP), as well as for the HEP community worldwide and we position our work in this global content. Specifically, we target the preservation of the scientific data, together with the software, documentation and computing environment needed to process, (re-)analyse or otherwise (re-)use the data. The target data volumes range from hundreds of petabytes (PB – 10^15 bytes) to hundreds of exabytes (EB – 10^18 bytes) for a target duration of several decades. The Use Cases driving data preservation are presented together with metrics that allow us to measure how close we are to meeting our goals, including the possibility for formal certification for at least part of this work. Almost all of the services that we describe are fully generic – the exception being A...

    Full Text Available Background: Immigrants from low-income countries comprise an increasing proportion of the population in Europe. Higher prevalence of obesity and nutrition related diseases, such as type 2 diabetes (T2D and cardiovascular disease (CVD is found in some immigrant groups, especially in South Asians. Aim: To review dietary changes after migration and discuss the implication for health and prevention among immigrants from low-income countries to Europe, with a special focus on South Asians. Method: Systematic searches in PubMed were performed to identify relevant high quality review articles and primary research papers. The searches were limited to major immigrant groups in Europe, including those from South Asia (India, Pakistan, Bangladesh, Sri Lanka. Articles in English from 1990 and onwards from Europe were included. For health implications, recent review articles and studies of particular relevance to dietary changes among South Asian migrants in Europe were chosen. Results: Most studies report on dietary changes and health consequences in South Asians. The picture of dietary change is complex, depending on a variety of factors related to country of origin, urban/rural residence, socio-economic and cultural factors and situation in host country. However, the main dietary trend after migration is a substantial increase in energy and fat intake, a reduction in carbohydrates and a switch from whole grains and pulses to more refined sources of carbohydrates, resulting in a low intake of fiber. The data also indicate an increase in intake of meat and dairy foods. Some groups have also reduced their vegetable intake. The findings suggest that these dietary changes may all have contributed to higher risk of obesity, T2D and CVD. Implications for prevention: A first priority in prevention should be adoption of a low-energy density – high fiber diet, rich in whole grains and grain products, as well as fruits, vegetables and pulses. Furthermore

    Osteoporosis is a disorder of bones with increasing risk among women. However, a number of modifiable factors can help in combating this disorder. Present study examined the relationship of diet and physical activity and risk of osteoporosis through biochemical tests, bone mass density (BMD) scores, and standard questionnaires. Genetic risk for osteoporosis, presence of osteoarthritis, and thyroid problems were found among 8%, 7%, and 3% of participants, respectively; and 78% had onset of menopause between 47 to 55 years of age. Results revealed that less intake of proteins, minerals, and diverse fruit and vegetable consumption was significantly (p≤0.05; 0.01) correlated with decreased BMD score and serum calcium. It was concluded that adequate intake of varied fruits and vegetables, good protein, habit of daily physical activity, adequate sun exposure, and dietary calcium, may play a promising role in decreasing the risk of osteoporosis among women of this age group.

    Full Text Available Background. Islands in the Mediterranean basin share particular habits and traditions and greater life expectancy than other European regions. In this paper, particular interest has been given to the effect of the Mediterranean diet, as well as nutritional services on CVD risk, on Mediterranean islands. Methods. Published results from observational studies were retrieved from electronic databases (Pubmed and Scopus and summarized. Results. Prevalence of CVD risk factors is increased. Adherence to the Mediterranean diet was moderate, even among the elderly participants. Furthermore, the presence of a dietician was associated with higher adherence to the Mediterranean dietary pattern and consequently lowers CVD risk. Conclusion. Adherence to the Mediterranean diet is reduced, while the prevalence of CVD risk factors is increasing at alarming rates. Public health nutrition policy has the opportunity to improve the health and quality of life of people living in isolated insular areas of the Mediterranean basin.

  19. Scientific Understanding from Long Term Observations: Insights from the Long Term Ecological Research (LTER) Program

    The network dedicated to Long Term Ecological Research (LTER) in the United States has grown to 24 sites since it was formed in 1980. Long-term research and monitoring are performed on parameters thatare basic to all ecosystems and are required to understand patterns, processes, and relationship to change. Collectively, the sites in the LTER Network provide opportunities to contrast marine, coastal, and continental regions, the full range of climatic gradients existing in North America, and aquatic and terrestrial habitats in a range of ecosystem types. The combination of common core areas and long-term research and monitoring in many habitats have allowed unprecedented abilities to understand and compare complex temporal and spatial dynamics associated with issues like climate change, effects of pollution, biodiversity and landuse. For example, McMurdo Dry Valley in the Antarctic has demonstrated an increase in glacier mass since 1993 which coincides with a period of cooler than normal summers and more than average snowfall. In contrast, the Bonanza Creek and Toolik Lake sites in Alaska have recorded a warming period unprecedented in the past 200 years. Nitrogen deposition effects have been identified through long-term watershed studies on biogeochemical cycles, especially at Coweeta Hydrological Lab, Harvard Forest, and the Hubbard Brook Experimental Forest. In aquatic systems, such as the Northern Temperate Lakes site, long-term data revealed time lags in effects of invaders and disturbance on lake communities. Biological recovery from an effect such as lake acidification was shown to lag behind chemical recovery. The long-term changes documented over 2 decades have been instrumental in influencing management practices in many of the LTER areas. In Puerto Rico, the Luquillo LTER demonstrated that dams obstruct migrations of fish and freshwater shrimp and water abstraction at low flows can completely obliterate downstream migration of juveniles and damage

    Weight loss and reduced fat-free mass are prevalent amongst patients with chronic obstructive pulmonary disease (COPD). However, the causes of this weight loss are not clear. The aims of this study are to investigate the factors affecting body weight and dietary intake in a group of outpatients with COPD, and to investigate any differences between adequately nourished and malnourished patients. In 103 stable outpatients, nutritional status was assessed using Body Mass Index (BMI) and upper arm anthropometry. Lung function, smoking status, exercise tolerance, dietary intake, dietary problems and health-related quality of life were assessed. Patients were classed as either adequately nourished or malnourished. Twenty-three per cent of subjects were classed as malnourished. The malnourished subjects had lower lung function measurements, suffered more dietary problems and had lower nutritional intake compared with the adequately nourished subjects. They also had poorer fatigue scores. In linear regression analysis, the factors that had the most effect on BMI were a low transfer factor, presence of early satiety, and being a current smoker. Important differences were found between adequately nourished and malnourished subjects. These differences move us closer to understanding how best to screen and treat this group of patients.

    Usual intake estimates describe long-term average intake of food and nutrients and food contaminants. The frequencies of fish and shellfish intake over a 30-day period from National Health and Examination Survey (NHANES 1999-2006) were combined with 24-h dietary recall data from NHANES 2003-2004 using a Monte Carlo procedure to estimate the usual intake of fish and shellfish in this study. Usual intakes were estimated for the US population including children 1 to fish intake (consumers only) was highest among children 1 to fish, salmon, and mackerel. Among children and teenage consumers, tuna, salmon, and breaded fish were the most frequently consumed fish; shrimp, scallops, and crabs were the most frequently consumed shellfish. The intake estimates from this study better reflect long-term average intake rates and are preferred to assess long-term intake of nutrients and possible exposure to environmental contaminants from fish and shellfish sources than 2-day average estimates.

  3. Modeling Maintenance of Long-Term Potentiation in Clustered Synapses: Long-Term Memory without Bistability

    Directory of Open Access Journals (Sweden)

    2015-01-01

    Full Text Available Memories are stored, at least partly, as patterns of strong synapses. Given molecular turnover, how can synapses maintain strong for the years that memories can persist? Some models postulate that biochemical bistability maintains strong synapses. However, bistability should give a bimodal distribution of synaptic strength or weight, whereas current data show unimodal distributions for weights and for a correlated variable, dendritic spine volume. Thus it is important for models to simulate both unimodal distributions and long-term memory persistence. Here a model is developed that connects ongoing, competing processes of synaptic growth and weakening to stochastic processes of receptor insertion and removal in dendritic spines. The model simulates long-term (>1 yr persistence of groups of strong synapses. A unimodal weight distribution results. For stability of this distribution it proved essential to incorporate resource competition between synapses organized into small clusters. With competition, these clusters are stable for years. These simulations concur with recent data to support the “clustered plasticity hypothesis” which suggests clusters, rather than single synaptic contacts, may be a fundamental unit for storage of long-term memory. The model makes empirical predictions and may provide a framework to investigate mechanisms maintaining the balance between synaptic plasticity and stability of memory.

  4. A new long-term care manifesto.

    This article argues for a fresh look at how we provide long-term care (LTC) for older persons. Essentially, LTC offers a compensatory service that responds to frailty. Policy debate around LTC centers on costs, but we are paying for something we really don't want. Building societal enthusiasm (or even support) for LTC will require re-inventing and re-branding. LTC has three basic components: personal care, housing, and health care (primarily chronic disease management). They can be delivered in a variety of settings. It is rare to find all three done well simultaneously. Personal care (PC) needs to be both competent and compassionate. Housing must provide at least minimal amenities and foster autonomy; when travel time for PC raises costs dramatically, some form of clustered housing may be needed. Health care must be proactive, aimed at preventing exacerbations of chronic disease and resultant hospitalizations. Enhancing preferences means allowing taking informed risks. Payment incentives should reward both quality of care and quality of life, but positive outcomes must be defined as slowing decline. Paying for services but not for housing under Medicaid would automatically level the playing field between nursing homes (NH) and community-based services. Regulations should achieve greater parity between NH and community care and include both positive and negative feedback. Providing post-acute care should be separate from LTC. Using the tripartite LTC framework, we can create innovative flexible approaches to providing needed services for frail older persons in formats that are both desirable and affordable. Such care will be more socially desirable and hence worth paying for.

    Benthic Foraminifera are used in a variety of applications employing numerous different methods, i.e. ecological monitoring, studying the effects of ocean acidification, reconstructing palaeo-bathymetry or investigating palaeo-salinity and palaeo-temperature to name only a few. To refine our understanding of ecological influences on larger benthic foraminiferal biology and to review inferences from field observations, culture experiments have become an indispensable tool. While culture experiments on smaller benthic foraminifera have become increasingly frequent in the past century, reports of the cultivation of symbiont bearing larger Foraminifera are rare. Generally, cultivation experiments can be divided into two groups: Culturing of populations and cultivation of single specimens allowing individual investigation. The latter differ form the former by several restrictions resulting from the need to limit individual motility without abridging microenvironmental conditions in the Foraminiferans artificial habitat, necessary to enable the individual to development as unfettered as possible. In this study we present first experiences and preliminary results of the long-term cultivation of larger benthic Foraminifera conducted at the 'Tropical Biosphere Research Station Sesoko Island, University of the Ryukyus', Japan, trying to reproduce natural conditions as closely as possible. Individuals of three species of larger benthic Foraminifera (Heterostegina depressa, Palaeonummulites venosus and Operculina complanata) have been cultured since April 2014. At the time of the general assembly the cultivation experiments will have been going on for more than one year, with the aim to investigate growth rates, longevities and reproduction strategies for comparison with results statistically inferred from application of the of the 'natural laboratory' method. The most important factor influencing foraminiferal health and development was found to be light intensity and light

    Confinement and inactivity induce considerable psychological and physiological modifications through social and sensory deprivation. The aim of the SFINCSS-99 experiment was to determine the cardiovascular and hormonal pattern of blood volume regulation during long-term isolation and confinement. Simulation experiments were performed in pressurized chambers similar in size to the volumes of modern space vehicles. Group I consisted of four Russian male volunteers, who spent 240 days in a 100-m(3 )chamber. Group II included four males (one German and three Russians) who spent 110 days in isolation (200-m(3) module). The blood samples, taken before, during and after the isolation period, were used to determine haematocrit (Ht), growth hormone (GH), active renin, aldosterone, and osmolality levels. From the urine samples, electrolytes, osmolality, nitrites, nitrates, cortisol, antidiuretic hormone (ADH), aldosterone, normetanephrine and metanephrine levels were determined. The increase in plasma volume (PV) that is associated with a tendency for a decrease in plasma active renin is likely to be due to decreased sympathetic activity, and concords with the changes in urinary catecholamine levels during confinement. Urinary catecholamine levels were significantly higher during the recovery period than during confinement. This suggests that the sympathoadrenal system was activated, and concords with the increase in heart rate. Vascular resistance is determined by not only the vasoconstrictor but also vasodilator systems. The ratio of nitrite/nitrate in urine, as an indicator of nitric oxide release, did not reveal any significant changes. Analysis of data suggests that the duration of the isolation was a main factor involved in the regulation of hormones.

    Full Text Available Respiratory syncytial virus (RSV is the most important pathogen in the etiology of respiratory infections in early life. 50% of children are affected by RSV within the first year of age, and almost all children become infected within two years. Numerous retrospective and prospective studies linking RSV and chronic respiratory morbidity show that RSV bronchiolitis in infancy is followed by recurrent wheezing after the acute episod. According to some authors a greater risk of wheezing in children with a history of RSV bronchiolitis would be limited to childhood, while according to others this risk would be extended into adolescence and adulthood. To explain the relationship between RSV infection and the development of bronchial asthma or the clinical pathogenetic patterns related to a state of bronchial hyperreactivity, it has been suggested that RSV may cause alterations in the response of the immune system (immunogenic hypothesis, activating directly mast cells and basophils and changing the pattern of differentiation of immune cells present in the bronchial tree as receptors and inflammatory cytokines. It was also suggested that RSV infection can cause bronchial hyperreactivity altering nervous airway modulation, acting on nerve fibers present in the airways (neurogenic hypothesis.The benefits of passive immunoprophylaxis with palivizumab, which seems to represent an effective approach in reducing the sequelae of RSV infection in the short- and long-term period, strengthen the implementation of prevention programs with this drug, as recommended by the national guidelines of the Italian Society of Neonatology. Proceedings of the 11th International Workshop on Neonatology and Satellite Meetings · Cagliari (Italy · October 26th-31st, 2015 · From the womb to the adultGuest Editors: Vassilios Fanos (Cagliari, Italy, Michele Mussap (Genoa, Italy, Antonio Del Vecchio (Bari, Italy, Bo Sun (Shanghai, China, Dorret I.

    The purpose of this study was to assess dietary intake of elite female volleyball players (EFVPs, n = 22) during the first 11 weeks of the competitive season. Further, we compared findings for total energy intake and specific macronutrient distribution with the established recommendations for high-intensity athletes. Subjects also engaged in periodized training and we assessed changes in body composition (BC) and strength. Twenty-two EFVPs had dietary intake (7-day dietary recall and food-frequency questionnaire), BC (body mass index (BMI), body fat percentage, fat mass, muscle mass), and 1-repetition maximum (1RM) strength (bench press, military press, back squat, power clean, clean and jerk, pull-over) assessed at baseline (T0, before preseason) and 11 weeks later (T11). Athletes consumed less total kilocalories and carbohydrates (CHO) compared with established recommendations (total kilocalories: 40.7 ± 5.2 kcal/(kg · day)(-1) vs. 50-80 kcal/(kg · day)(-1); CHO: 4.3 ± 0.6 g/(kg · day)(-1) vs. 5-8 g/(kg · day)(-1)). Further, subjects consumed greater protein (2.1 ± 0.4 g/(kg · day)(-1)) compared with recommendations (1.6-1.8 g/(kg · day)(-1)) and greater fat (36.1 ± 4.6% of total kilocalories) than recommendations (20%-35% of total kilocalories). There were improvements (p 0.05) in BMI or military press and pull-over. Back squat (p = 0.054; +33.0% ± 83.7%) and power clean (p = 0.056; +26.2% ± 49.0%) increases approached significance. Our findings indicate that EFVPs improved BC and strength despite a dietary intake different from recommendations. This is possibly due to different substrate utilization during exercise in females versus males, thus new recommendations should be considered for high-intensity athletes, which are sex-specific.

    1994-01-01

    The Long-Term Orbit Predictor (LOP) trajectory propagation program is a useful tool in lifetime analysis of orbiting spacecraft. LOP is suitable for studying planetary orbit missions with reconnaissance (flyby) and exploratory (mapping) trajectories. Sample data is included for a geosynchronous station drift cycle study, a Venus radar mapping strategy, a frozen orbit about Mars, and a repeat ground trace orbit. LOP uses the variation-of-parameters method in formulating the equations of motion. Terms involving the mean anomaly are removed from numerical integrations so that large step sizes, on the order of days, are possible. Consequently, LOP executes much faster than programs based on Cowell's method, such as the companion program ASAP (the Artificial Satellite Analysis Program, NPO-17522, also available through COSMIC). The program uses a force model with a gravity field of up to 21 by 21, lunisolar perturbation, drag, and solar radiation pressure. The input includes classical orbital elements (either mean or oscillating), orbital elements of the sun relative to the planet, reference time and dates, drag coefficients, gravitational constants, planet radius, rotation rate. The printed output contains the classical elements for each time step or event step, and additional orbital data such as true anomaly, eccentric anomaly, latitude, longitude, periapsis altitude, and the rate of change per day of certain elements. Selected output is additionally written to a plot file for postprocessing by the user. LOP is written in FORTRAN 77 for batch execution on IBM PC compatibles running MS-DOS with a minimum of 256K RAM. Recompiling the source requires the Lahey F77 v2.2 compiler. The LOP package includes examples that use LOTUS 1-2-3 for graphical displays, but any graphics software package should be able to handle the ASCII plot file. The program is available on two 5.25 inch 360K MS-DOS format diskettes. The program was written in 1986 and last updated in 1989. LOP is

    The Swedish Nuclear Fuel and Waste Management Company is responsible for the management and disposal of Sweden's radioactive waste. It is intended to deposit the spent nuclear fuel in a deep geological repository. This repository shall keep the radiotoxic material separated from humans and the environment for extended periods, from decades to millennia and possibly to geological timescales. During this time perspective climate induced changes such as shore-level displacement and evolution of permafrost and ice sheets are expected to occur which may affect the repository. The possible occurrence, extent and duration of these long-term changes, are therefore of interest when considering the assessment of repository performance and safety. The main climate parameters determining both surface and subsurface conditions are temperature and precipitation. As a result of the last advance of the Weichselian ice sheet only few geological archives exist, which contain information on past climatic conditions in Sweden before c 16,000 years BP. The purpose of this literature review is to compile and evaluate available information from Scandinavian, Northern and Central European geological archives, which record climatic conditions during the Weichselian time period. The compilation provides paleotemperature data sets, which may be used to explore the possible evolution of periglacial permafrost in Sweden. This report is a synopsis of 22 publications detailing climatic and environmental changes during the Weichselian time period in Northwestern Europe based on quantified paleotemperature records. Some of the data is presented as temperature curves which were digitised specifically for this report. The time range covered by the different publications varies considerably. Only few authors dealt with the whole Weichselian period and the majority cover only a few thousand years. This however is not considered to influence the reliability of the archives.

    Full Text Available Micronutrient deficiencies and imbalanced dietary intake tend to occur during the reproductive period among women in China. In accordance with traditional Chinese culture, pregnant women are commonly advised to follow a specific set of dietary precautions. The purpose of this study was to assess dietary intake data and identify risk factors for nutritional inadequacy in pregnant women from urban and rural areas of Deyang region, Sichuan province of China. Cross-sectional sampling was applied in two urban hospitals and five rural clinics (randomly selected in Deyang region. Between July and October 2010, a total of 203 pregnant women in the third trimester, aged 19–42 years, were recruited on the basis of informed consent during antenatal clinic sessions. Semi-structured interviews on background information and 24-h dietary recalls were conducted. On the basis of self-reported height and pre-pregnancy weight, 68.7% of the women had a pre-pregnancy body mass index (BMI within the normal range (18.5 ≤ BMI < 25, 26.3% were found to be underweight with a BMI <18.5 (20.8% in urban vs. 35.6% in rural areas, while only 5.1% were overweight with a BMI ≥30. In view of acceptable macronutrient distribution ranges (AMDRs the women’s overall dietary energy originated excessively from fat (39%, was low in carbohydrates (49.6%, and reached the lower limits for protein (12.1%. Compared to rural areas, women living in urban areas had significantly higher reference nutrient intake (RNI fulfillment levels for energy (106.1% vs. 93.4%, fat (146.6% vs. 119.7%, protein (86.9% vs. 71.6%, vitamin A (94.3% vs. 65.2%, Zn (70.9% vs. 61.8%, Fe (56.3% vs. 48%, Ca (55.1% vs. 41% and riboflavin (74.7% vs. 60%. The likelihood of pregnant women following traditional food recommendations, such as avoiding rabbit meat, beef and lamb, was higher in rural (80% than in urban (65.1% areas. In conclusion, culturally sensitive nutrition education sessions are necessary for both

    2005-01-01

    Two distinct forms of consolidated associative memory are known in Drosophila: long-term memory and so-called anesthesia-resistant memory. Long-term memory is more stable, but unlike anesthesia-resistant memory, its formation requires protein synthesis. We show that flies induced to form long-term memory become more susceptible to extreme stress (such as desiccation). In contrast, induction of anesthesia-resistant memory had no detectable effect on desiccation resistance. This finding may hel...

    Full text of publication follows: In recent years, there has been a growing interest in the evaluation of nutrient fluxes and radioactive contaminants in forest and agricultural ecosystems. Several studies on forest ecosystems have been carried out, mostly in Europe, after the Chernobyl accident. Japanese forest sites and native plant species of the Marshall Islands have also been extensively investigated. These studies have been used for various purposes, including the development of models for predicting plant concentrations from soil concentration measurements or the long term of dietary contamination by radiocesium following a fallout nuclear. Cesium is an alkali metal just like potassium and its behavior in nature, as well as in the human body, is similar to that of potassium. Uptake of 137 Cs from contaminated soil represents a significant pathway of human radiation exposure, either due to the direct consumption of cereals, fruits and vegetables or, indirectly, following consumption of milk and meat from animals fed on contaminated vegetable matter. The decline of 137 Cs levels as function of time of fruit trees is of interest given its long life in the field. Therefore, the cesium behavior is important in the design of management strategies to mitigate any negative health effects of radioactivity on the environment. It is also important to apply the current knowledge of the transport and distribution of salts derived from forest ecosystems in agricultural ecosystems, especially for tropical fruit trees. So far, in the South hemisphere there have been only a few studies on this subject, without conclusive results. With this aim, the Laboratory of Radioecology (L.A.R.A.) of the Universidade Federal Fluminense has been performing analyzes of 137 Cs and 40 K concentrations in several tropical plants (guava, mango, avocado, pomegranate, papaya, manioc and chili pepper trees) in order to determine the accumulation of these radionuclides throughout these trees and

    The increasing demand for elderly care services, pressures on inpatient average length of stay and payment levels, and potential financial rewards from providing additional services, makes long-term care look attractive to hospitals. Long-term care, however, is not for every hospital. Before deciding to establish long-term care services, management should examine how the service fits within the hospital's strategic plan. The action plan below provides guidance in evaluating a decision to use hospital facilities for long-term care. Examine how long-term care services fit within the hospital's strategic plan. Study area demographics and competitors to assess the need and supply of long-term care services. Survey the medical staff, consumers and payers to determine attitudes, perceptions and interests regarding long-term care services. Develop a facility plan that identifies areas of excess capacity that can be most easily converted into long-term care with minimal effects on hospital operations. Prepare a financial feasibility analysis of the contribution margin and return on investment attributable to long-term care services. Include an impact analysis on hospital operations. Establish a management task force to develop a detailed implementation plan including assigned individual responsibilities and related timetable. Develop an effective marketing plan designed to generate increased patient market share.

    The aims of the present study were to investigate the current exposure levels of persistent organochlorine compounds (OCs) in adipose tissues intraoperatively collected from 40 patients over 20 years undergoing non-cancer-related surgery residing in Northern region of Tunisia (Bizerte), which constitutes an exemplary case, and examined association between levels of contamination and both socio-demographic characteristics and dietary habits. Concentration of hexachlorobenzene (HCB), hexachlorocyclohexane isomers (α-HCH, β-HCH, γ-HCH and δ-HCH), dichlorodiphenyltrichloroethane isomers (p,p'-DDT and o,p'-DDT) and metabolites (p,p'-DDE, o,p'-DDE, p,p'-DDD and o,p'-DDD) and 12 polychlorinated biphenyls (PCBs) congeners were measured using capillary gas chromatography with electron capture detector. Overall, residue levels of OCs followed the decreasing order of DDTs > PCBs > HCB > HCHs. DDTs levels ranged from 74.49 to 1834.76ngg(-1) lipid and contributing to more than 90% to the sum of organochlorine pesticides (OCPs). p,p'-DDE was the most abundant in all samples and the p,p'-DDT/p,p'-DDE ratio (range between 1.85% and 58.45%) suggesting recent and ongoing exposure to banned commercial DDT products. PCB concentrations varied from 29.27 to 322.58ngg(-1) lipid and PCB-180, PCB-153 and PCB-138 were the dominant congeners accounting for 70% of total PCBs. We did not find significant correlations between OC exposure levels and sex, parity, habitat areas and smoking habits. In females, the adipose tissue concentrations of DDTs, HCB and PCB-118 were positively correlated with age. There was statistically significant relationship between body mass index (BMI) changes and the adipose tissue levels of HCB and HCHs. No association was found between OCPs levels and dietary factors. However, our study suggests that fish consumption may be an important contributor of PCBs adipose tissue content of PCBs in Tunisian people. The presented work is highly significant, being the

    In this work, we focus on one of the most useful techniques of efficient study habits: How to improve long-term memory. We show that if a student carries a number of recalling sessions of the material studied and if he/she carries them at specific times, the student will be able to retain this material for a long time and hence be prepared for the exams. We argue that a student who conscientiously uses the proper techniques of efficient study habits will be able to achieve higher results than the student who does not. Moreover, a student equipped with the proper study skills will spend much less time to learn a subject than a student who has no effective study habits. After providing a summary of the most essential personal skills needed to be a successful student--concentration skills, how to take notes in class, how to prepare for and take exams---we give an extensive presentation on the techniques of improving long-term memory.

    Full Text Available Experience suggests that many celiac patients suffer from persistent symptoms despite a long-term gluten-free diet (GFD. We investigated the prevalence and severity of these symptoms in patients with variable duration of GFD. Altogether, 856 patients were classified into untreated (n = 128, short-term GFD (1–2 years, n = 93 and long-term GFD (≥3 years, n = 635 groups. Analyses were made of clinical and histological data and dietary adherence. Symptoms were evaluated by the validated GSRS questionnaire. One-hundred-sixty healthy subjects comprised the control group. Further, the severity of symptoms was compared with that in peptic ulcer, reflux disease, inflammatory bowel disease (IBD and irritable bowel syndrome (IBS. Altogether, 93% of the short-term and 94% of the long-term treated patients had a strict GFD and recovered mucosa. Untreated patients had more diarrhea, indigestion and abdominal pain than those on GFD and controls. There were no differences in symptoms between the short- and long-term GFD groups, but both yielded poorer GSRS total score than controls (p = 0.03 and p = 0.05, respectively. Furthermore, patients treated 1–2 years had more diarrhea (p = 0.03 and those treated >10 years more reflux (p = 0.04 than controls. Long-term treated celiac patients showed relatively mild symptoms compared with other gastrointestinal diseases. Based on our results, good response to GFD sustained in long-term follow-up, but not all patients reach the level of healthy individuals.

    Longer average life expectancies and an ageing society have made long-term care an urgent and important issue in Taiwan. Although the implementation of Long-Term Care Ten-year Project four years ago has begun showing success in terms of assessing Taiwan's needs in terms of long-term care services and resources, there has been little forward progress in terms of training, recruiting and maintaining more competent professionals in the long-term care sector. This paper explores the current state of long-term care competency in Taiwan and educational strategies in place to improve the competency of long-term care professionals. Results indicate that the term geriatric competency embraces sub-competencies in direct care, communication, assessment, teamwork, cultural sensitivities and career care competencies. The term long-term care competency embraces the sub-competencies of supervision, management, information technology, resource management, and organizational skill. As a main contributor to effective long-term care, the nursing profession must employ effective strategies to develop competency-based education. Also, the profession must have an adequate supply of competent manpower to effectively respond to Taiwan's aging society.

    This paper aims to investigate long-term dynamic behaviors of autonomous fractional differential equations with effective numerical method. The long-term dynamic behaviors predict where systems are heading after long-term evolution. We make some modification and transplant cell mapping methods to autonomous fractional differential equations. The mapping time duration of cell mapping is enlarged to deal with the long memory effect. Three illustrative examples, i.e. fractional Lotka-Volterra equation, fractional van der Pol oscillator and fractional Duffing equation, are studied with our revised generalized cell mapping method. We obtain long-term dynamics, such as attractors, basins of attraction, and saddles. Compared with some existing stability and numerical results, the validity of our method is verified. Furthermore, we find that the fractional order has its effect on the long-term dynamics of autonomous fractional differential equations.

    Full Text Available It is important to confirm the long-term strength of rock materials for the purpose of evaluating the long-term stability of rock engineering. In this study, a series of triaxial creep tests were conducted on granite gneiss under different pore pressures. Based on the test data, we proposed two new quantitative methods, tangent method and intersection method, to confirm the long-term strength of rock. Meanwhile, the isochronous stress-strain curve method was adopted to make sure of the accuracy and operability of the two new methods. It is concluded that the new methods are suitable for the study of the long-term strength of rock. The effect of pore pressure on the long-term strength of rock in triaxial creep tests is also discussed.

To choose a high cadmium area polluted by smelting and mining north of Guangdong province and a cadmium-free area with a similar economic level, and living and eating habit of residents as a contrast from April 2011 to August 2012. Stratified random sampling and clustered sampling method were adopted to choose the non-occupationally cadmium-exposed respondents who have lived in local area for more than 15 years, older than 40 years, having local rice and vegetable as the main dietary source, with simple and relatively stable diet, and without diabetes, kidney disease, thyroid disease, liver disease or other history of chronic disease. This study included 298 respondents, of whom 155 were in cadmium exposure group and 143 in control group. Questionnaires was used to acquire their health status and their morning urine samples were collected. Electrolytically coupled plasma mass spectrometry (ICP-MS) was used to test the concentrations of sodium(Na), magnesium (Mg), phosphorus (P), potassium (K), calcium (Ca), copper (Cu), zinc (Zn) and iodine (I). The Mann-Whitney U test method was used to compare the differences of concentrations of urinary cadmium, Na, Mg, P, K, Ca, Cu, Zn, I, and the ratio of Na to K (Na/K), Ca to P (Ca/P) between exposed group and control group.χ(2) test was used to compare the abnormal rate of urinary cadmium between exposed group and control group. Pearson correlation and multiple regression method were used to investigate the relationship between urinary cadmium levels, gender, age, smoking, passive smoking, and minerals. The urinary cadmium level P50 (P25-P75) in exposed group was 5.45 (2.62-10.68) μg/g·cr, which was higher than that of the control group, which was 1.69 (1.22-2.36) μg/g·cr (Z=-10.49,Phuman body.

    African American (AA) and Hispanic/Latina (HL) women report lower rates of physical activity (PA) and poorer dietary habits compared to their white counterparts. Religiosity can act as a protective factor for health; however, the relationship between religiosity, PA, and diet is unclear. This study aimed to investigate the influence of religiosity on PA and fruit and vegetable (FV) and fat consumption in minority women. Health is Power (HIP) was a 6-month intervention where participants (AA: 63%; HL: 37%) were randomized to a PA or FV group. Questionnaires assessed religiosity at baseline and PA, FV and fat consumption at baseline and post-intervention. Hierarchical linear regression models were used to investigate religiosity as a predictor of change in PA, FV and fat, while controlling for demographics. AA women had significantly higher religiosity scores (M = 44.15, SD = 10.66) compared to H/L women (M = 35.11, SD = 12.82; t(251) = 5.86, p Religiosity was not a significant predictor of PA or diet (p religiosity and change in PA and diet. More longitudinal studies are needed to explore the role of religiosity in the health of minority women.

    With the discovery of hundreds of exoplanets and a potentially huge number of Earth-like planets waiting to be discovered, the conditions for their habitability have become a focal point in exoplanetary research. The classical picture of habitable zones primarily relies on the stellar flux allowing liquid water to exist on the surface of an Earth-like planet with a suitable atmosphere. However, numerous further stellar and planetary properties constrain habitability. Apart from "geophysical" processes depending on the internal structure and composition of a planet, a complex array of astrophysical factors additionally determine habitability. Among these, variable stellar UV, EUV, and X-ray radiation, stellar and interplanetary magnetic fields, ionized winds, and energetic particles control the constitution of upper planetary atmospheres and their physical and chemical evolution. Short- and long-term stellar variability necessitates full time-dependent studies to understand planetary habitability at any point ...

    2009-10-01

    Dr. Styliani (Stella) Kafka of the Department of Terrestrial Magnetism, Carnegie Institute of Washington, requests AAVSO observers to perform long-term photometric monitoring on a number of magnetically active dwarf stars, with an observing frequency of one observation every three days taken with one or more filters. When multiple filters are available, the preferred observations are (in order of precedence): Rc, V, Ic, and B. Please observe such that you obtain a signal to noise of at least 50 (100 or higher is preferred). These objects are all nearby dwarfs known or suspected to have magnetic activity, primarily of the UV Ceti (flare star) or BY Draconis subtypes. Long-term photometric monitoring of these objects will be used in conjunction with other multiwavelength observations from ground-based facilities including the Magellan 6.5-meter and DuPont 2.5-meter telescopes in Chile to understand the long-term magnetic activity cycles of these stars. Such a study can reveal information about the physical natures of these stars, but also about their near space environments and habitability for life. These objects are red, and the variability amplitudes are low, often well below 0.1 magnitudes. The long-term variability due to stellar activity cycles may be much lower. Photometric accuracy rather than the number of observations are key to the success of this project. Unaccounted-for atmospheric effects such as extinction will likely overwhelm any long-term signal from these stars. Observers are strongly urged to fully calibrate their systems and to carefully reduce and transform their photometry to standard photometric passbands, including corrections for airmass/atmospheric extinction. Parameters for 40 objects are given. Observations should be submitted to the AAVSO International Database.

    The International Space Station will allow extended habitation in space and long-term exposure to microgravity (microG). A concern is the impact of long-term microG exposure on the ability of species to reproduce. The model often used to simulate microG is rat hindlimb suspension (HLS), where the hindlimbs are elevated above the cage floor with a tail harness. Experiments described here are the first to examine the effect of long-term HLS on testicular function in adult male rats. Free-roaming (controls), animals with only the tail harnessed but hindlimbs in contact with the cage floor (TO), and HLS animals were tested for 6 wk. Cryptorchidism was prevented in TO and HLS animals by partial constriction of the inguinal canal with sutures. All parameters were compared at the end of the 6-wk experiment. Testicular weights and spermatogenesis were significantly reduced by HLS, such that no spermatogenic cells beyond round spermatids were present and epididymides were devoid of mature sperm. In many tubules, loss of all germ cells, except a few spermatogonia, resulting in histopathology similar to the Sertoli cell, was observed. Spermatogenesis appeared unaffected in control and TO animals. Sertoli and Leydig cell appearance, testosterone, luteinizing hormone, and follicle-stimulating hormone levels, and epididymal and seminal vesicle weight were unchanged by HLS. Cortisone was not elevated by HLS; thus stress may not be a factor. These results demonstrate that spermatogenesis is severely inhibited by long-term HLS, whereas testicular androgen production is not. These results have significant implications regarding serious effects of long-term exposure to microG on the reproductive capability of scrotal mammals, including humans.

    Full Text Available Objective: The objective of this study was to determine the prevalence of obesity among students of medical colleges of Lahore and to study its correlation with high-caloric diet intake and physical inactivity. Study Design: A cross-sectional survey was conducted at four medical colleges of Lahore, Pakistan between March and June 2012. Methods: A total of 244 medical students (85 males, 159 females of the median age of 20 years (range: 18–25 were randomly included in the study. Anthropometric measures were obtained. High-caloric diet intake and physical profile were assessed through a self-reported questionnaire. The relationships between obesity indices (body mass index [BMI], waist-to-hip ratio were investigated and correlated with the studied dietary and physical activity factors. Results: Approximately, 30.5% males and 16% females had BMI ≥25.0 kg/m2 overall affecting 21% of total medical students. Central obesity was found in 46% of male and 31.4% of female students. Central obesity was associated with a higher total daily caloric intake, studying at private medical college and male gender. Overall, 197 of 244 (80.7% students played no sports in college. Median time to watch television or work on the computer was 120 min a day (range: 30–420. Only 70 (28.7% students had regular walk or jogging. Conclusion: A substantial proportion of Pakistani medical students were overweight or obese. Higher total daily caloric intake was associated with central obesity but not a BMI >25. Physical activity parameters favored an overall sedentary aptitude for medical students.

    (on the order of a few thousand times the annual dose from natural background radiation), the increase in the long-term rate of cancer development as a result of lower, chronic exposures due to the contamination of the habitat and of the dietary foodstuffs, will pose very difficult scientific, economic, political, and societal problems. Most areas close to sites of detonation (i.e., within about 1000 km) would be primarily impacted by radionuclides with shorter half-lives (i.e., less than 2 months), e.g., Zirconium-95, Niobium-95, Iodine-131, Iodine-132, Iodine-133, Barium-140, Lanthanum-140, and Strontium-89. Conversely, most areas at further distances would be primarily impacted by radionuclides with longer half-lives, e.g., Strontium-90 and Cesium-137 (each with half-lives of 30 years). Contaminating radionuclides with very long half-lives, e.g., Plutonium-239, which has a half-life of 24,000 years, will almost never limit habitation despite widespread fear of them.

    2003-01-01

    The purpose of this review is to summarize existing data on the long-term safety and efficacy of stimulant treatment, and how long-term stimulant treatment of children with attention deficit hyperactivity disorder (ADHD) affects their outcome. Existing controlled studies of children with ADHD treated and untreated with stimulants, as well as long-term prospective follow-up studies, are reviewed. Children with ADHD treated with stimulants for as long as 2 years continue to benefit from the treatment, with improvements observed in ADHD symptoms, comorbid oppositional defiant disorder, and academic and social functioning, with no significant problems of tolerance or adverse effects. Long-term, prospective follow-up studies into adulthood show that stimulant treatment in childhood has slight benefits regarding social skills and self-esteem. Long-term adverse effects from stimulant treatment in childhood regarding adult height or future substance abuse have not been supported by existing studies.

    2008-01-01

    This study examines the long-term unemployment rate and various health outcomes across Canadian communities to estimate employment-related health inequalities in these communities. The study uses cross-sectional community-level health data along with data on the long-term employment rate for various communities across Canada to quantify health inequalities among these communities. The health outcomes that are considered in this study include total and disease specific mortality rates; health conditions such as high blood pressure, diabetes, injuries, and self rated health; and life expectancies at birth and at age 65. Health inequalities are estimated using the concentration index, which is used to measure health inequalities along socioeconomic dimensions. The concentration index is estimated by a regression of weighted relative health (ill health) over weighted cumulative relative rank of the populations. All the estimates are provided separately for males and females. The findings of the study support the existence of inequalities in community health outcomes as related to the long-term employment rates in those communities. Communities with lower long term employment rates (higher unemployment rates) have poorer health outcomes in terms of higher mortality rates, worse health conditions, and shorter life expectancies. Health inequalities related to long-term employment have important policy implications. They call for policies that would increase and maintain long term employment rates as part of a broader socioeconomic approach to health. Long term employment ensures income security and prevents the psychosocial experiences leading to mental and physical ill health.

    2001-11-01

    Long-term stewardship consists of those actions necessary to maintain and demonstrate continued protection of human health and the environment after facility cleanup is complete. As the Department of Energy’s (DOE) lead laboratory for environmental management programs, the Idaho National Engineering and Environmental Laboratory (INEEL) administers DOE’s long-term stewardship science and technology efforts. The INEEL provides DOE with technical, and scientific expertise needed to oversee its long-term environmental management obligations complexwide. Long-term stewardship is administered and overseen by the Environmental Management Office of Science and Technology. The INEEL Long-Term Stewardship Program is currently developing the management structures and plans to complete INEEL-specific, long-term stewardship obligations. This guidance document (1) assists in ensuring that the program leads transition planning for the INEEL with respect to facility and site areas and (2) describes the classes and types of criteria and data required to initiate transition for areas and sites where the facility mission has ended and cleanup is complete. Additionally, this document summarizes current information on INEEL facilities, structures, and release sites likely to enter long-term stewardship at the completion of DOE’s cleanup mission. This document is not intended to function as a discrete checklist or local procedure to determine readiness to transition. It is an overarching document meant as guidance in implementing specific transition procedures. Several documents formed the foundation upon which this guidance was developed. Principal among these documents was the Long-Term Stewardship Draft Technical Baseline; A Report to Congress on Long-Term Stewardship, Volumes I and II; Infrastructure Long-Range Plan; Comprehensive Facility Land Use Plan; INEEL End-State Plan; and INEEL Institutional Plan.

  20. Long-term dynamics of high mass ratio multiples

    Science.gov (United States)

    Li, Gongjie

    This thesis presents a series of studies on the dynamics of high mass ratio multiples, with applications to planetary systems orbiting stars and stellar systems orbiting supermassive black holes (SMBHs). Almost two thousand exoplanetary systems have recently been discovered, and their configurations gave rise to new puzzles to planetary formation theories. We studied the dynamics of planetary systems aiming to understand how the configuration of planetary system is sculptured and to probe the origin of planetary systems. First, we discussed hierarchical three-body dynamics, which can be applied to planets that are orbiting a star while perturbed by a planet or a star that is farther away. The perturbation from the farther object can flip the planetary orbits and produce counter orbiting hot Jupiters, which cannot be formed in the classical planetary formation theory. In addition, we have studied the scatter encounter of planetary systems in clusters, which produce eccentric and inclined planets. Moreover, we investigated the obliquity variation of planets, which can be applied to exoplanetary systems. The obliquity variation is important to the habitability of the exoplanets. The long term dynamics is also important to stellar systems orbiting SMBHs. SMBHs are common in the center of galaxies and lead to rich dynamical interactions with nearby stars. At the same time, dynamical features of the nearby stars reveal important properties of the SMBHs. The aforementioned hierarchical three-body dynamics can be applied to stars near SMBH binaries, which are natural consequences of galaxy mergers. We found that the distribution of stars surrounding one of the SMBHs results in a shape of torus due to the perturbation from the other SMBH, and the dynamical interactions contribute to an enhancement of tidal disruption rates, which can help identify the SMBH binaries. In addition, we investigated the heating of stars near SMBHs, where the heating of stars due to gravitational

    Many studies have shown that memory is enhanced when study sessions are spaced apart rather than massed. This spacing effect has been shown to have a lasting benefit to long-term memory when the study phase session follows the encoding session by 24 hours. Using a spacing paradigm we examined the impact of sleep and spacing gaps on long-term declarative memory for Swahili-English word pairs by including four spacing delay gaps (massed, 12 hours same-day, 12 hours overnight, and 24 hours). Results showed that a 12-hour spacing gap that includes sleep promotes long-term memory retention similar to the 24-hour gap. The findings support the importance of sleep to the long-term benefit of the spacing effect.

    2016-01-01

    There are limited studies on long-term outcomes of childhood onset nephrotic syndrome (NS). A majority of children with NS have steroid-sensitive nephrotic syndrome (SSNS). Steroid-resistant nephrotic syndrome (SRNS) is associated with a high risk of developing end-stage renal disease. Biomarkers and analysis of genetic mutations may provide new information for prognosis in SRNS. Frequently relapsing and steroid-dependent NS is associated with long-term complications, including dyslipidemia, cataracts, osteoporosis and fractures, obesity, impaired growth, and infertility. Long-term complications of SSNS are likely to be under-recognized. There remain many gaps in our knowledge of long-term outcomes of childhood NS, and further study is indicated.

    Despite neonatal diagnosis and life-long dietary restriction of galactose, many patients with classic galactosemia grow to experience significant long-term complications. Among the more common are speech, cognitive, behavioral, ovarian and neurological/movement difficulties. Despite decades of research, the pathophysiology of these long-term complications remains obscure, hindering prognosis and attempts at improved intervention. As a first step to overcome this roadblock we have begun to explore long-term outcomes in our previously reported GALT-null Drosophila melanogaster model of classic galactosemia. Here we describe the first of these studies. Using a countercurrent device, a simple climbing assay, and a startle response test to characterize and quantify an apparent movement abnormality, we explored the impact of cryptic GALT expression on phenotype, tested the role of sublethal galactose exposure and galactose-1-phosphate (gal-1P) accumulation, tested the impact of age, and searched for potential anatomical defects in brain and muscle. We found that about 2.5% residual GALT activity was sufficient to reduce outcome severity. Surprisingly, sublethal galactose exposure and gal-1P accumulation during development showed no effect on the adult phenotype. Finally, despite the apparent neurological or neuromuscular nature of the complication we found no clear morphological differences between mutants and controls in brain or muscle, suggesting that the defect is subtle and/or is physiologic rather than structural. Combined, our results confirm that, like human patients, GALT-null Drosophila experience significant long-term complications that occur independently of galactose exposure, and serve as a proof of principle demonstrating utility of the GALT-null Drosophila model as a tool for exploring genetic and environmental modifiers of long-term outcome in GALT deficiency.
