    Full Text Available One of the aims in domestic pig breeding has been to increase the size of litters resulting in variation in birth weight of piglets. Pig breeding has also resulted in increased body muscle mass. Muscles with the same size can consist either of large number of thin muscle fibres or small number of thick muscle fibres. Larger body muscle content means that in living animal the heart must pump blood to larger muscle mass than earlier. Our interest in this study was to investigate the relationship between the pig’s birth weight and (i growth performance and carcass composition, (ii the size of organs, and (iii the mean muscle fibre cross-sectional area at slaughter. The study consisted of twenty pigs slaughtered at the age of 165±2 days. The day after the slaughter, the carcass composition was determined by dissecting the chilled carcass into lean, fat, bones, and skin and organs were weighed. The average cross sectional area of muscle fibres was determined from three fast-twitch muscles longissimus dorsi, semimembranosus, gluteus superficialis, and two slow-twitch muscles infraspinatus and masseter. The birth weight of pigs ranged from 0.9 to 2.2 kg. We found no clear relationships between the birth weight and the pig’s growth performance from birth to slaughter. When the birth weight increased the heart weight at slaughter increased as well (P < 0.01. The heart weight was higher in those pigs with high carcass weight (P < 0.05 and with the high weight of total muscle mass in the carcass (P < 0.001. The cross sectional area of muscle fibres in M. longissimus dorsi (P < 0.05, M. semimembranosus (P < 0.10, and M. gluteus superficialis (P < 0.05 was larger in those pigs with low birth weight compared to those found in pigs with high birth weight.;

    This is a case report of premature low birth weight infant with hypoplasia of left heart structures and a large malaligned VSD who underwent successful staged approach of biventricular repair. We obtained qualitative and quantitative echocardiographic, MRI, and conventional catheterization data to support stepwise strategy towards LV rehabilitation to sustain adequate cardiac output. A thorough and intense follow-up has shown significant growth of left heart structures and favorable clinical status following staged biventricular repair. Our data indicate usefulness of qualitative and quantitative advanced complimentary multi-imaging modalities in predicting the postnatal growth potential of critically underdeveloped left heart structures.

    People often express emotion in language using weight (e.g., a heavy heart, light-hearted, light humor, or heavy-handed), but the question remains whether these expressions of emotion are rooted in the body. Six experiments used a priming paradigm to explore the metaphoric relation between weight perception and emotional words. Experiments 1 and 2 investigated the influence of weight perception on judgments of emotional words and the influence of emotional words on judgments of weight, respec...

    Objective: To explore the impact of weight management and related medication intervention based on body weight changes on cardiac function among patients with chronic congestive heart failure (CHF). Methods: Using prospective, randomized, controlled study methods, consecutive CHF patients, who hospitalized in our department from June 2014 to June 2016 ( n =350), were randomly divided into intervention group ( n =175) and control group ( n =175). Patients in the intervention group received weight management guidance and the post discharge diuretic drugs regimen was adjusted based on body weight changes. The control group received routine medical care post discharge. Left ventricular ejection fraction (LVEF), B type natriuretic peptide precursor (NT-proBNP), 6 minutes walk distance and NYHA classification at one day before discharge and after 6 months were compared between the two groups respectively. Results: Follow-up visit data were not available from 6 patients in the control and intervention group respectively. NYHA classification, LVEF, NT-proBNP and 6 minutes walk distance were similar between the two groups at one day before discharge (all P >0.05). After 6 months, the LVEF and 6 minutes walk distance were significantly higher while NT-proBNP level was significantly lower in the intervention group compared to the control group (all P weight remained unchanged in the intervention group, while body weight tended to be higher in the control group compared to one day before discharge. Conclusion: The weight management and diuretic drug regimen adjudgment intervention based on body weight changes can improve cardiac function and reduced re-hospitalization rate in CHF patients.

    People often express emotion in language using weight (e.g., a heavy heart, light-hearted, light humor, or heavy-handed), but the question remains whether these expressions of emotion are rooted in the body. Six experiments used a priming paradigm to explore the metaphoric relation between weight perception and emotional words. Experiments 1 and 2 investigated the influence of weight perception on judgments of emotional words and the influence of emotional words on judgments of weight, respectively. A significant difference between the consistent condition (e.g., lightness corresponds to positive words and heaviness corresponds to negative words) and the inconsistent condition (e.g., lightness corresponds to negative words and heaviness corresponds to positive words) was found in Experiment 1 but not in Experiment 2. Experiments 3, 4, and 5 were conducted to exclude potential confounds. Experiment 6 was a repeated-measures study that was conducted to verify the weight-emotion effect. The study confirmed that weight perception affected judgments of emotional words. The results contribute to the growing literature on conceptual metaphor theory and embodied cognition theory.

All devices underestimated both outcomes compared to reference methods. The percentage error for heart rate was small across the devices (range: 1-9% but greater for energy expenditure (9-43%. Similarly, limits of agreement were considerably narrower for heart rate (ranging from -27.3 to 13.1 bpm than energy expenditure (ranging from -266.7 to 65.7 kcals across devices.These devices accurately measure heart rate. However, estimates of energy expenditure are poor and would have implications for people using these devices for weight loss.

    2017-05-01

    Polycystic ovary syndrome (PCOS) is an endocrine disease closely related to several risk factors of cardiovascular disease. Obese women with PCOS show altered autonomic modulation. The results of studies investigating cardiac autonomic functions of normal-weight women with PCOS are conflicting. The aim of the study was to assess the reactivity of cardiac sympathovagal balance in normal-weight women with PCOS by heart rate variability analysis. We examined the heart rate variability in 60 normal-weight women with PCOS and compared them with that in 60 age-matched healthy women having a similar metabolic profile. Time and frequency domain parameters of heart rate variability were analyzed based on 5-min-long continuous electrocardiography recordings for the following 3 periods: (1) during rest in supine position, (2) during controlled breathing, and (3) during isometric handgrip exercise. Time and frequency domain parameters of heart rate variability for the 3 periods assessed were similar in the two groups. Although modified Ferriman-Gallwey score and serum testosterone and luteinizing hormone levels were significantly higher in women with PCOS, homeostatic model assessment-insulin resistance (HOMA-IR) was not different the between the PCOS and control groups. There were no significant correlations between serum testosterone levels and heart rate variability parameters among the study population. The findings of this study suggest that the reactivity of cardiac sympathovagal balance is not altered in normal-weight women with PCOS having a normal HOMA-IR.

    Background: Weight loss can be caused by a loss of body mass due to metabolism and by water loss as unsensible water loss, sweating, or excretion in feces and urine. Although weight loss during sleep is a well-known phenomenon, it has not yet been studied in relation to sleep structure or autonomic tonus during sleep. Our study is proposed to be a first step in assessing the relationship between overnight weight loss, sleep structure, and HRV (heart rate variability) parameters.Methods: Twent...

    To determine the effects of weight loss on heart rate recovery (HRR) in overweight women with polycystic ovary syndrome (PCOS). A 10-week prospective clinical intervention. Clinical research unit. Fifty-seven overweight and obese women with PCOS (age: 29.8 +/- 0.8 years; body mass index [BMI] 36.2 +/- 0.7 kg/m(2)). A dietary plan of 5-6 MJ/day ( approximately 30% energy restricted). Heart rate recovery (defined as the reduction in heart rate after 1 minute from peak heart rate after a graded treadmill test to exhaustion), weight, waist circumference, blood pressure, glucose, insulin, homeostasis model assessment of insulin resistance, and sex steroids before and after the intervention. The mean percentage of weight loss was (-6.7 +/- 0.4%). There were significant reductions in waist circumference (-6.9 +/- 0.6 cm), blood pressure (-4.9/-2.5 +/- 1.2/1.2 mm Hg), fasting insulin (-3.4 +/- 0.7 mU/L), fasting glucose (-0.17 +/- 0.05 mmol/L), homeostasis model assessment of insulin resistance (-0.43 +/- 0.09), T (-0.38 +/- 0.07 nmol/L), free androgen index (-2.86 +/- 0.58), and an increase in sex hormone-binding globulin [SHBG] (5.86 +/- 1.12 nmol/L). The HRR improved from 30.9 +/- 1.1 to 38.0 +/- 1.1 beats/min and that was related to the reduction in body weight (r = -0.34) and waist circumference (r = -0.27). Weight loss in overweight and obese women with PCOS is associated with improvements in HRR, which suggests improved autonomic function. This highlights the importance of weight loss to reduce the cardiovascular disease risk in these women. Crown Copyright 2010. Published by Elsevier Inc. All rights reserved.

    Full Text Available Abstract Background Body Mass Index (BMI is widely used to assess the impact of obesity on cardiometabolic risk in children but it does not always relate to central obesity and varies with growth and maturation. Waist-to-Height Ratio (WHtR is a relatively constant anthropometric index of abdominal obesity across different age, sex or racial groups. However, information is scant on the utility of WHtR in assessing the status of abdominal obesity and related cardiometabolic risk profile among normal weight and overweight/obese children, categorized according to the accepted BMI threshold values. Methods Cross-sectional cardiometabolic risk factor variables on 3091 black and white children (56% white, 50% male, 4-18 years of age were used. Based on the age-, race- and sex-specific percentiles of BMI, the children were classified as normal weight (5th - 85th percentiles and overweight/obese (≥ 85th percentile. The risk profiles of each group based on the WHtR ( Results 9.2% of the children in the normal weight group were centrally obese (WHtR ≥0.5 and 19.8% among the overweight/obese were not (WHtR Conclusion WHtR not only detects central obesity and related adverse cardiometabolic risk among normal weight children, but also identifies those without such conditions among the overweight/obese children, which has implications for pediatric primary care practice.

    The aim of the study was to show the effect of heart transplant donor-recipient weight mismatch on mortality, right-ventricular (RV) failure, and medium-term control of systemic blood pressure. From 2000 to 2008 inclusive, 161 patients undergoing orthotopic heart transplantation at our unit were retrospectively analyzed. The cohort was divided into three groups of similar size depending on the tertile ranges of the donor-recipient weight ratio. Median follow-up was 4.81 years. Donor-recipient body weight ratio was analyzed with respect to intubation time, time in intensive care unit (ITU), development of RV failure, medium-term survival, and freedom from medium-term hypertension. The median age was 115 months (23 days to 18 years), at a median weight of 26.9 kg (3-88 kg) at transplant. Median donor-recipient weight ratio was 1.61 (0.62-3.25). Mean intubation time was 448 h (SD 749.2), mean time in the ITU 302.7 h (SD 617.8). On linear regression, these were not related to donor-recipient weight ratio. A total of 38 patients (23.6%) developed postoperative RV failure. Nearly one-fifth (18.9) of patients in the lowest tertile group developed RV failure. In the middle tertile group, 24.5% developed RV failure and 28.8% in the upper tertile of weight mismatch, although this was not statistically significant (p = 0.48). On survival analysis, there was a higher mortality among those with the lowest tertile of mismatch (log-rank p = 0.04), but there was no difference in midterm survival on condition of survival to discharge (log-rank p = 0.14). There was also no association between weight ratio and freedom from medium-term hypertension as measured on serial 24-h ambulatory blood pressure monitoring (log-rank p = 0.39). There were nine patients in whom the weight mismatch was 3 or greater. There was no association between this 'extreme' mismatch group and either midterm mortality (p = 0.76) or freedom from hypertension (p = 0.62), but this was associated with the need for

    1988-01-01

    The oxygen binding properties of the blood of the camelid species vicuna, llama, alpaca and dromedary camel were measured and evaluated with respect to interspecific differences. The highest blood oxygen affinity, not only among camelids but of all mammals investigated so far, was found in the vicuna (P50 = 17.6 Torr compared to 20.3-21.6 Torr in the other species). Low hematocrits (23-34%) and small red blood cells (21-30 microns 3) are common features of all camelids, but the lowest values are found in the Lama species. Capillary densities were determined in heart and soleus muscle of vicuna and llama. Again, the vicuna shows exceptional values (3720 cap/mm2 on average in the heart) for a mammal of this body size. Finally, heart weight as percent of body weight is higher in the vicuna (0.7-0.9%) than in the other camelids studied (0.5-0.7%). The possibility that these parameters, measured in New World tylopodes at sea level, are not likely to change considerably with transfer to high altitude, is discussed. In the vicuna, a unique combination of the following features seems to be responsible for an outstanding physical capability at high altitude: saturation of blood with oxygen in the lung is favored by a high blood oxygen affinity, oxygen supply being facilitated by low diffusion distances in the muscle tissue. Loading, as well as unloading, of oxygen is improved by a relatively high oxygen transfer conductance of the red blood cells, which is due to their small size and which compensates the negative effect of a low hematocrit on the oxygen conductance of blood.(ABSTRACT TRUNCATED AT 250 WORDS)

    2014-03-01

    The prevalence of overweight and obesity in children has reached a concerning plateau in the past three decades, with overweight or obesity impacting approximately one-third of youth. Unhealthy weight-related behaviors, including dieting, unhealthy weight control practices and binge eating, are also a great public health concern for young people given both their high prevalence and harmful consequences. Food-related parenting practices, including food restriction and pressure-to-eat, have been associated with higher weight status, as well as the use of unhealthy weight-related behaviors, in children and adolescents. Physicians and other health care providers who work with families should discourage parents from using food restriction and pressure-to-eat parenting practices with their child or adolescent. Alternatively, parents should be empowered to promote healthy eating by focusing on making nutritious food items readily available within their home and modeling healthy food choices for their child or adolescent.

    2018-01-27

    The molecular pathophysiology of heart failure, which is one of the leading causes of mortality, is not yet fully understood. Heart failure can be regarded as a systemic syndrome of aging-related phenotypes. Wnt/β-catenin signaling and the p53 pathway, both of which are key regulators of aging, have been demonstrated to play a critical role in the pathogenesis of heart failure. Circulating C1q was identified as a novel activator of Wnt/β-catenin signaling, promoting systemic aging-related phenotypes including sarcopenia and heart failure. On the other hand, p53 induces the apoptosis of cardiomyocytes in the failing heart. In these molecular mechanisms, the cross-talk between cardiomyocytes and non-cardiomyocytes (e,g,. endothelial cells, fibroblasts, smooth muscle cells, macrophages) deserves mentioning. In this review, we summarize recent advances in the understanding of the molecular pathophysiology underlying heart failure, focusing on Wnt/β-catenin signaling and the p53 pathway.

    The aim of the study was to establish the effects of a range of psychosocial factors on weight changes and risk of obesity. The study population consisted of the 4,753 participants in the third (1991-1994) and fourth wave (2001-2003) of the Copenhagen City Heart Study, Denmark. At baseline...... the participants were asked comprehensive questions on major life events, work stress, vital exhaustion, social network, economic hardship, and intake of sleep medication. Weight and height were measured by health professionals. Weight changes and incident obesity was used as outcome measures. The participants...... in the associations between social network, economic hardship and weight gain or obesity. The number of psychosocial risk factors, as an indicator for clustering, was not associated with weight gain or obesity. In conclusion, major life events and vital exhaustion seem to play a role for weight gain and risk...

  7. Birth weight, childhood body mass index and risk of coronary heart disease in adults: combined historical cohort studies.

    Directory of Open Access Journals (Sweden)

    Lise Geisler Andersen

    Full Text Available BACKGROUND: Low birth weight and high childhood body mass index (BMI is each associated with an increased risk of coronary heart disease (CHD in adult life. We studied individual and combined associations of birth weight and childhood BMI with the risk of CHD in adulthood. METHODS/PRINCIPAL FINDINGS: Birth weight and BMI at age seven years were available in 216,771 Danish and Finnish individuals born 1924-1976. Linkage to national registers for hospitalization and causes of death identified 8,805 CHD events during up to 33 years of follow-up (median = 24 years after age 25 years. Analyses were conducted with Cox regression based on restricted cubic splines. Using median birth weight of 3.4 kg as reference, a non-linear relation between birth weight and CHD was found. It was not significantly different between cohorts, or between men and women, nor was the association altered by childhood BMI. For birth weights below 3.4 kg, the risk of CHD increased linearly and reached 1.28 (95% confidence limits: 1.13 to 1.44 at 2 kg. Above 3.4 kg the association weakened, and from about 4 kg there was virtually no association. BMI at age seven years was strongly positively associated with the risk of CHD and the relation was not altered by birth weight. The excess risk in individuals with a birth weight of 2.5 kg and a BMI of 17.7 kg/m(2 at age seven years was 44% (95% CI: 30% to 59% compared with individuals with median values of birth weight (3.4 kg and BMI (15.3 kg/m(2. CONCLUSIONS/SIGNIFICANCE: Birth weight and BMI at age seven years appeared independently associated with the risk of CHD in adulthood. From a public health perspective we suggest that particular attention should be paid to children with a birth weight below the average in combination with excess relative weight in childhood.

    This study recruited 16 industrial workers to examine the effects of material, weight, and base area of container on reduction of grip force (ΔGF) and heart rate for a 100-m manual carrying task. This study examined 2 carrying materials (iron and water), 4 carrying weights (4.4, 8.9, 13.3, 17.8 kg), and 2 base areas of container (24 × 24 cm, 35 × 24 cm). This study showed that carrying water significantly increased ΔGF and heart rate as compared with carrying iron. Also, ΔGF and heart rate significantly increased with carrying weight and base area of container. The effects of base area of container on ΔGF and heart rate were greater in carrying water condition than in carrying iron condition. The maximum dynamic effect of water on ΔGF and heart rate occurred when water occupied ~60%-80% of full volume of the container.

    To evaluate fibrosis and fibrosis-related gene expression in the myocardium of pediatric subjects with single ventricle with right ventricular failure. Real-time quantitative polymerase chain reaction was performed on explanted right ventricular myocardium of pediatric subjects with single ventricle disease and controls with nonfailing heart disease. Subjects were divided into 3 groups: single ventricle failing (right ventricular failure before or after stage I palliation), single ventricle nonfailing (infants listed for primary transplantation with normal right ventricular function), and stage III (Fontan or right ventricular failure after stage III). To evaluate subjects of similar age and right ventricular volume loading, single ventricle disease with failure was compared with single ventricle without failure and stage III was compared with nonfailing right ventricular disease. Histologic fibrosis was assessed in all hearts. Mann-Whitney tests were performed to identify differences in gene expression. Collagen (Col1α, Col3) expression is decreased in single ventricle congenital heart disease with failure compared with nonfailing single ventricle congenital heart disease (P = .019 and P = .035, respectively), and is equivalent in stage III compared with nonfailing right ventricular heart disease. Tissue inhibitors of metalloproteinase (TIMP-1, TIMP-3, and TIMP-4) are downregulated in stage III compared with nonfailing right ventricular heart disease (P = .0047, P = .013 and P = .013, respectively). Matrix metalloproteinases (MMP-2, MMP-9) are similar between nonfailing single ventricular heart disease and failing single ventricular heart disease, and between stage III heart disease and nonfailing right ventricular heart disease. There is no difference in the prevalence of right ventricular fibrosis by histology in subjects with single ventricular failure heart disease with right ventricular failure (18%) compared with those with normal right

    We assessed the nutritional status of patients with congenital heart disease (CHD) to evaluate the role of dietary intake in impaired weight for patient length. Underweight patients with CHD underwent nutritional counseling to evaluate the role of this intervention in improvement of weight for length. We prospectively evaluated a clinical protocol for nutritional assessment and counseling in patients with CHD. Eligible patients were enrolled from a cardiology clinic during a 13-month period. Initial anthropometric measurements and measurements of dietary intake of underweight and normal-weight patients were compared. Initial and follow-up measurements of underweight patients who received nutritional counseling were compared. Nineteen underweight patients with CHD and 16 normal-weight patients with CHD, aged 1 month to 2 years, were studied. Exclusion criteria included noncardiac factors that could affect growth (eg, low birth weight, Down syndrome, gastrointestinal deficit, and any severe abnormality of the central nervous system). Seventeen of the 19 underweight patients underwent nutritional counseling in the presence of a parent every 2 months for 6 months. Caloric and protein intakes were maximized using high-calorie formulas. Baseline dietary intake was lower in underweight patients than in normal-weight patients (mean percentage of the recommended daily allowance of calories, 89% vs 108%). Follow-up evaluation in normal-weight patients showed no change in percentage of ideal body weight for length. Follow-up evaluation in underweight patients showed improvement in mean dietary intake (from 90% to 104% of the recommended daily allowance of calories) and in mean percentage of ideal body weight for length after intervention (from 83.1% to 88.3%). Nutritional evaluation of patients with CHD demonstrated that underweight children had inadequate diets. Underweight patients with CHD who received nutritional counseling showed increased dietary intake and improved

    Weight-related discrimination is prevalent and associated with health impairments for those who are targeted, which underscores the need of antidiscrimination legislation. This study is the first to examine public support of weight-related antidiscrimination laws or policies in Germany, compared to the US and Iceland. In a representative German population sample (N = 2,513), public support for general and employment-specific weight-related antidiscrimination policies, weight-based victimization, and weight bias internalization were measured through established self-report questionnaires. Half of the German population sample agreed with antidiscrimination policies. General antidiscrimination laws received lower support than employment-specific laws. Support for policies considering obesity a physical disability was greatest in Germany, whereas support for employment-specific antidiscrimination laws was lower in Germany than in the US and Iceland. Total support for weight-related antidiscrimination policies was significantly predicted by lower age, female gender, obese weight status, residence in West Germany, church membership, and readiness to vote in elections. German support for weight-related antidiscrimination policies is moderate. Increasing awareness about weight-related discrimination and laws prohibiting this behavior may help to promote policy acceptance. © 2017 The Author(s) Published by S. Karger GmbH, Freiburg.

    Worldwide, the numbers of women who have a pre-existing cardiovascular disease or develop cardiac problems during pregnancy are increasing and, due to the lack of evidenced-based data, this provides challenges for the treating physician. Cardiovascular disease in pregnancy is a complex topic as women can present either pre- or post-partum, due to a pre-existing heart disease such as operated on or unoperated on congenital heart disease, valvular heart disease, chronic hypertension, or familial dilated cardiomyopathy. Women often present with symptoms and signs of acute heart failure. On the other hand, there are diseases which are directly related to pregnancy, such as hypertensive disorders of pregnancy and peripartum cardiomyopathy, or where pregnancy increases risk of a disease as, for example, the risk of myocardial infarction. These diseases can have long-term implications to the life of the affected women and their families. There is, in particular, a paucity of data from developing countries of this unique disease pattern and its presentations. This review summarizes the current knowledge of the incidence and prevalence of pregnancy-related cardiovascular disease in women presenting pre- or post-partum.

    In 2010, the American Heart Association established the concept of ideal cardiovascular health. Nationally representative data estimated that Healthy Diet Score. In a cohort of young adults (N=196), we aimed to investigate the prevalence of ideal cardiovascular health and ideal Healthy Diet Score and its association to weight gain over a 4-year follow-up period. Anthropometric measures, blood pressure, and blood samples were taken according to standardized procedures. Dietary intake was measured by a 3-day food diary and verified by a registered dietitian. We observed that only 0.5% of our sample met the criteria for ideal cardiovascular health and only 4.1% met the criteria for an ideal Healthy Diet Score. The components of the Healthy Diet Score with the lowest observance were consumption of fruits and vegetables (9.7%) and whole grains (14.8%). Meeting zero or one out of five of the Healthy Diet Score components was associated with increased risk of weight gain over 4 years compared with meeting at least two components (P=0.03). With the exception of dietary criteria, prevalence was high for achieving ideal levels of the remaining six cardiovascular health metrics. In conclusion, in this sample of young adults, a very low prevalence of ideal overall cardiovascular health was observed, mainly driven by poor dietary habits, and a poor Healthy Diet Score was associated with increased weight gain.

    In the past two decades, infant mortality rates in the United States declined in African-American and White populations. Despite this, racial disparities in infant mortality rates have increased and rates of low birth weight deliveries have shown little change. In this study, we examine temporal changes in birth weight distributions, birth weight specific neonatal mortality, and the birth weight threshold for an adverse risk of survival within both racial groups in order to explore the mechanisms for the disparities in infant mortality rates. Single live births born to South Carolina resident mothers between 1975 and 1994 and considered White or African-American based on the mother's report of maternal race on the birth certificate were selected for investigation. We define the birth weight threshold for adverse survival odds as the birth weight at which 50% or more of infants in the population died within the first month of life. Despite significant increases in very low birth weight percentages, neonatal mortality rates markedly declined. Birth weight specific neonatal mortality decreased for both races, although greater reductions accrued to White low birth weight infants. By the end of the study period, the birth weight at which over 50% of newborns died within the first month of life was 696 g for Whites and 673 g for African-Americans. The ongoing decline in neonatal mortality is mainly due to reductions in birth weight specific neonatal mortality, probably related to high-risk obstetric and neonatal care. Technological developments in these areas may have differentially benefited Whites, resulting in an increasing racial disparity in mortality rates. Moreover, the relatively greater and increasing mortality risk from postmaturity and macrosomia in infants of African-America mothers may further exacerbate the racial gap in infant mortality.

    Locus of control, i.e. the degree of an individual's belief on the control of his/her life, has been related to many health outcomes, including weight loss in overweight/obese individuals. No information is available on the impact of locus of control in maintaining weight loss. We aimed to investigate the effect of locus of control in weight loss maintenance and explore potential associations with lifestyle factors. Study participants included 239 individuals (41% males) who had lost at least 10% of body weight in the past and either maintained the loss (maintainers: weight maintenance of at least 10% of initial weight) or regained it (regainers). Locus of control was defined by a relevant multi-dimensional scale; participants were categorised to internals and externals, based on "internal" and "others" sub-scales. A significant interaction was found between locus of control and weight loss maintenance status (p locus of control. Individualised treatment, according to locus of control, may increase weight loss maintenance rates in former overweight/obese individuals. Copyright © 2015 Elsevier Ltd. All rights reserved.

    Full Text Available Objective: Reconstructive and replacement operations of diseased cardiac valves are commonly practiced these days. It may be noted that the choice of proper reconstructive intervention and prosthetic replacement might require the normal morphometric measurements of heart in relation with general body parameters, like age and height. So, this study was undertaken to measure various measurements of heart and its relation with age and height of the individual. Materials and Methods: Sixty five normal post-mortem hearts of adults were taken from the mortuary of Department of Forensic Medicine. Age of the individual was noted. Length of the deceased was measured with a measuring tape from the level of vertex to the outer border of heel. Length (from apex to base, breadth (at broadest diameter and thickness of the heart were measured with slide callipers. Weight was measured with weighing machine. Results: The mean length, breadth, thickness of heart in males and females are 11.25, 8.78, 3.97 cm and 10.60, 8.31, 3.63 cm. The mean weight of heart in males and females was 323 and 276 gms. There was significant correlation with weight of individual and weight of heart in males. There was significant correlation with age of individual and length of heart in females. Conclusion: This study will be helpful for cardiothoracic surgeons while doing surgery on hearts.

    Individuals with obesity often experience unfair treatment because of their body weight. Such experiences are associated with binge eating, but less is known about its association with other eating-related behaviors and whether these relations are specific to discrimination based on weight or extend to other attributions for discrimination. The present research uses a large national sample (N = 5129) to examine whether weight discrimination is associated with diet and meal rhythmicity, in addition to overeating, and whether these associations generalize to nine other attributions for discrimination. We found that in addition to overeating, weight discrimination was associated with more frequent consumption of convenience foods and less regular meal timing. These associations were generally similar across sex, age, and race. Discrimination based on ancestry, gender, age, religion, and physical disability were also associated with overeating, which suggests that overeating may be a general coping response to discrimination. Unfair treatment because of body weight is associated with unhealthy eating-related behaviors, which may be one pathway through which weight discrimination increases risk for weight gain and obesity.

    Randomized control trials of statins have not demonstrated significant benefits in outcomes of heart failure (HF). However, randomized control trials may not always be generalizable. The aim was to determine whether statin and statin type-lipophilic or -hydrophilic improve long-term outcomes in Africans with HF. This was a retrospective longitudinal study of HF patients aged ≥18 years hospitalized at a tertiary healthcare center between January 1, 2009 and December 31, 2013 in Ghana. Patients were eligible if they were discharged from first admission for HF (index admission) and followed up to time of all-cause, cardiovascular, and HF mortality or end of study. Multivariable time-dependent Cox model and inverse-probability-of-treatment weighting of marginal structural model were used to estimate associations between statin treatment and outcomes. Adjusted hazard ratios were also estimated for lipophilic and hydrophilic statin compared with no statin use. The study included 1488 patients (mean age 60.3±14.2 years) with 9306 person-years of observation. Using the time-dependent Cox model, the 5-year adjusted hazard ratios with 95% CI for statin treatment on all-cause, cardiovascular, and HF mortality were 0.68 (0.55-0.83), 0.67 (0.54-0.82), and 0.63 (0.51-0.79), respectively. Use of inverse-probability-of-treatment weighting resulted in estimates of 0.79 (0.65-0.96), 0.77 (0.63-0.96), and 0.77 (0.61-0.95) for statin treatment on all-cause, cardiovascular, and HF mortality, respectively, compared with no statin use. Among Africans with HF, statin treatment was associated with significant reduction in mortality. © 2017 The Authors. Published on behalf of the American Heart Association, Inc., by Wiley Blackwell.

    Full Text Available Background. The repeated loss and regain of body weight, referred to as weight cycling, may be associated with negative health complications. Given today’s obesity epidemic and related interventions to address obesity, it is increasingly important to understand contexts and factors associated with weight loss maintenance. This study examined BMI among individuals who had previously participated in a 12-week, evidence-based, nationally disseminated nutrition and physical activity program designed for overweight and obese middle-aged and older women. Methods. Data were collected using follow-up surveys. Complete height and weight data were available for baseline, 12-week program completion (post-program and follow-up (approximately 3 years later for 154 women (response rate = 27.5%; BMI characteristics did not differ between responders and nonresponders. Results. Mean BMI decreased significantly from baseline to post-program (−0.5, P<0.001 and post-program to follow-up (−0.7, P<0.001. Seventy-five percent of survey respondents maintained or decreased BMI post-program to follow-up. Self-efficacy and social support for healthy eating behaviors (but not physical activity were associated with BMI maintenance or additional weight loss. Conclusions. These findings support the durability of weight loss following participation in a relatively short-term intervention.

    To quantify the impact of a commercial weight management program on weight change in obese patients with coronary heart disease. An observational, single-center pilot study in the Netherlands. Forty-five patients diagnosed with a recent acute coronary syndrome and a body mass index of >30 kg/m2 were recruited. The commercial weight management intervention (Weight Watchers) promotes a hypoenergetic and balanced diet, increased physical activity, and group support. The program included weekly 30-minute in-hospital meetings with an experienced coach. The program was offered in parallel with a cardiac rehabilitation program. Thirty-five patients completed the program. Of these patients, 32 patients (91%) decreased body weight. Mean weight change was -5.8 kg (range: +0.6 kg to -15.4 kg), and 20 patients (57%) achieved the target of 5% weight loss of their initial weight. Twenty-seven patients continued the commercial weight loss program after 14 weeks, the mean followup of these patients was 34 weeks and their mean weight change was -9.1 kg (range: 0.0-23.0 kg). Obese patients, discharged after an acute coronary syndrome, who were referred to a commercial weight management program, achieved significant weight loss. Although this is a nonrandomized pilot study with patients who were selected by motivation and by the ability to participate in the program, the proportion of weight loss is significant and promising.

  9. Parenting style as a predictor of adolescent weight and weight-related behaviors.

    2010-04-01

    Current research indicates that specific parenting styles are associated with adolescent overweight, dietary intake, and physical activity; but most of the research has been cross-sectional, making it difficult to determine the temporal order of these associations. The current study adds to the previous research by examining 5-year longitudinal associations between parenting style and adolescent weight and weight-related behaviors. Data from Project EAT, a population-based study with adolescents from diverse ethnic and socioeconomic backgrounds, were used. Adolescents (N = 2,516) from 31 Minnesota schools completed in-class assessments in 1999 (Time 1) and mailed surveys in 2004 (Time 2). Multiple linear regression models were used to predict mean levels of adolescent outcomes at Time 2 from parenting style at Time 1. Time 1 maternal authoritative parenting style predicted lower body mass index in adolescent sons and daughters at Time 2. Time 1 paternal permissive parenting style predicted more fruits and vegetables intake in daughters at Time 2. Significant associations were not found between parenting style and adolescent physical activity. Findings suggest that authoritative parenting style may play a protective role related to adolescent overweight and that the dimension of warmth and/or caring in the parent-adolescent relationship may be important in relation to female adolescent healthy dietary intake. Further exploration of opposite sex parent-adolescent dyad patterns related to parenting style and adolescent weight and weight-related behaviors is warranted.

    To describe the weight status and weight-related behaviors of children commencing school. This study is a representative cross-sectional survey of Australian children in their first year of schooling (n=1141) in 2010. Height and weight were measured, and parents reported their child's diet, physical activity and screen-time. 18.7% of children were overweight/obese. Compared with non-overweight/obese peers, overweight/obese boys were 1.73 times (95% CI 1.08, 2.79) as likely to exceed recommended screen time and 2.07 times (95% CI 1.11, 3.87) as likely to eat dinner three or more times/week in front of the TV. Overweight/obese girls were twice as likely to have a TV in their bedroom (OR 2.00, 95% CI 1.12, 3.59) and usually be rewarded with sweets for good behavior (OR 1.96, 95% CI 1.09, 3.51) and were 1.65 times as likely to be inactive (95% CI 1.08, 2.55). We showed that many children begin school with established weight-related behaviors that occur in the home environment. The inclusion of parents and the home environment in intervention strategies will be important to support changes to reduce childhood obesity. The weight status and weight-related behaviors of children entering school may potentially be a general indicator of the overall effectiveness of obesity prevention interventions among preschool-aged children.

    Approximately one-third of children in the USA are either overweight or obese. Understanding the perceptions of children is an important factor in reversing this trend. An online survey was conducted with children to capture their perceptions of weight, overweight, nutrition, physical activity and related socio-behavioural factors. Within the USA. US children (n 1224) aged 8-18 years. Twenty-seven per cent of children reported being overweight; 47·1% of children overestimated the rate of overweight/obesity among US children. A higher percentage of self-classified overweight children (81·9%) worried about weight than did self-classified under/normal weight children (31·1%). Most children (91·1%) felt that it was important to not be overweight, for both health-related and social-related reasons. The majority of children believed that if someone their age is overweight they will likely be overweight in adulthood (93·1%); get an illness such as diabetes or heart disease in adulthood (90·2%); not be able to play sports well (84·5%); and be teased or made fun of in school (87·8%). Children focused more on food/drink than physical activity as reasons for overweight at their age. Self-classified overweight children were more likely to have spoken with someone about their weight over the last year than self-classified under/normal weight children. Children demonstrated good understanding of issues regarding weight, overweight, nutrition, physical activity and related socio-behavioural factors. Their perceptions are important and can be helpful in crafting solutions that will resonate with children.

    Absence of an adequate reason for anxiety is a criterion for pathological anxiety. However, the presence of danger or fear-provoking stimuli may even be a risk factor for anxiety and does not exclude that there is additionally pathological anxiety too. The question is, to what degree can heart-related anxiety be explained by the severity of illness or trait anxiety? Two hundred and nine patients (37.8% women) from a cardiology inpatient unit completed the Heart-Anxiety-Questionnaire, Progression-Anxiety-Questionnaire, Job-Anxiety-Scale and the State-Trait-Anxiety-Inventory. The severity of cardiac illness was rated by the treating cardiologists using the Multidimensional Severity of Morbidity Rating. Time absent from work due to sickness was assessed as an indicator for illness-related impairment. Heart anxiety was significantly related to progression anxiety and, to a lesser extent, trait anxiety and indicators of subjective symptoms of somatic illness. No association was found with medical ratings for prognosis, multimorbidity, or reduction in life expectancy. Heart-related anxiety is a symptom of an anxiety disorder. Although partially dependent on subjective suffering, it cannot be explained by the severity of medical illness. Treatment of health-related anxieties should focus on how to cope with subjective symptoms of illness.

    Full Text Available Abstract Background The use of prescription anti-obesity medication (AOM is becoming increasingly common as treatment options grow and become more accessible. However, AOM may not be without a wide range of potentially negative impacts on patient functioning and well being. The Treatment Related Impact Measure (TRIM-Weight is an obesity treatment-specific patient reported outcomes (PRO measure designed to assess the key impacts of prescription anti-obesity medication. This paper will present the validation findings for the TRIM-Weight. Methods The online validation battery survey was administered in four countries (the U.S., U.K., Australia, and Canada. Eligible subjects were over age eighteen, currently taking a prescription AOM and were currently or had been obese during their life. Validation analyses were conducted according to an a priori statistical analysis plan. Item level psychometric and conceptual criteria were used to refine and reduce the preliminary item pool and factor analysis to identify structural domains was performed. Reliability and validity testing was then performed and the minimally importance difference (MID explored. Results Two hundred and eight subjects completed the survey. Twenty-one of the 43 items were dropped and a five-factor structure was achieved: Daily Life, Weight Management, Treatment Burden, Experience of Side Effects, and Psychological Health. A-priori criteria for internal consistency and test-retest coefficients for the total score and all five subscales were met. All pre-specified hypotheses for convergent and known group validity were also met with the exception of the domain of Daily Life (proven in an ad hoc analysis as well as the 1/2 standard deviation threshold for the MID. Conclusion The development and validation of the TRIM-Weight has been conducted according to well-defined principles for the creation of a PRO measure. Based on the evidence to date, the TRIM-Weight can be considered a brief

    Different pathways likely underlie the association between early weight gain and cardiovascular disease risk. We examined whether birth weight for length relationship and weight gain up to 2 years of age are associated with lipid profiles and blood pressure (BP) in early adolescence and determined whether childhood adiposity mediates these associations. Data from QUALITY (Quebec Adipose and Lifestyle Investigation in Youth), a cohort of white children with parental history of obesity, were analyzed (n=395). Sex-specific weight for length z scores from birth to 2 years were computed. Rate of postnatal weight gain was estimated using individual slopes of weight for length z -score measurements. Percentage of body fat was measured at 8 to 10 years. Fasting lipids and BP were measured at 10 to 12 years. Using path analysis, we found indirect effects of postnatal weight gain, through childhood adiposity, on all outcomes: Rate of postnatal weight for length gain was positively associated with childhood adiposity, which in turn was associated with unfavorable lipid and BP levels in early adolescence. In contrast, small beneficial direct effects on diastolic BP z scores, independent of weight at other time points, were found for birth weight for length (β=-0.05, 95% CI, -0.09 to -0.002) and for postnatal weight gain (β=-0.02, 95% CI, -0.03 to -0.002). Among children with at least 1 obese parent, faster postnatal weight gain leads to cardiovascular risk factors in early adolescence through its effect on childhood adiposity. Although heavier newborns may have lower BP in early adolescence, this protective direct effect could be offset by a deleterious indirect effect linking birth weight to later adiposity. © 2017 The Authors.

    Autonomic dysregulation is a well-established feature in adults with obesity but not in children. Since this dysregulation could contribute to weight dynamics, this study aimed to compare autonomic regulation in children with obesity and normal-weight peers and to track autonomic status during weight reduction. Sixty children with obesity and 27 age- and sex-matched normal-weight healthy participants were included. Heart rate variability (HRV) was assessed at baseline and during a mental stress test and a subsequent recovery period. Children with obesity were investigated both upon admission and discharge. Upon admission, no significant differences in HRV parameters were found for normal-weight participants and those with obesity. Inpatient treatment led to significant changes in HRV with increase in general variability (standard deviation of the normal-to-normal interval (SDNN), P Children with obesity had sympathetic activation similar to normal-weight controls during mental stress with subsequent return to baseline values, and weight loss did not affect this profile. A weight reduction program induced a change in autonomic activity in children with obesity toward parasympathetic dominance but had no influence on autonomic nervous system reactivity during stress conditions. © 2015 The Obesity Society.

    Gestational weight gain is an important predictor of the health of the newborn. It is affected by body mass index of the women. This study was conducted to find out gestational weight gain according to Institute of Medicine 2009 recommendation and relationship of newborn birth weight to body mass index and gestational weight gain of the women. It was cross sectional, hospital based study. The women, who attended at term pregnancy for delivery and having recorded first trimester body weight, were included in the study. Their body mass index was calculated and they were stratified into 4 groups according to body mass index. The gestational weight gain was calculated by subtracting first trimester body weight from body weight at the time of admission for delivery. All the women were followed till delivery. The newborn birth weight was taken immediately after delivery. A total of 227 women were enrolled in the study. More than half of the women had normal body mass index. There were 84 (37%) overweight and obese women. Mean gestational weight gain was 10.21 kg, and mean weight of the newborn was 3.05 kg. There were equal number of women who had adequate weight gain and less weight gain according to recommendation. Excess weight gain was seen in 34 (15%) women. Women of higher body mass index and women who had gain more weight during pregnancy had larger newborns. Body mass index and gestational weight gain of the women were important predictors of birth weight of the newborn. There is a positive correlation between gestational weight gain of the women and birth weight of the newborn.

    Full Text Available Abstract Background Obesity is emerging as a public health problem among adolescents in India. The aim of this study was to describe specific weight-related concerns among school-going youth in Delhi, India and to assess the prevalence of weight control behaviors, including healthy and unhealthy ones. Differences by weight status, gender, grade level, and school-type (a proxy for SES in this setting are considered. Methods This study is cross-sectional by design. A sample of eighth and tenth graders (n = 1818 enrolled in Private (middle-high SES and Government (low SES schools (n = 8 in Delhi, India participated. All students' height and weight were measured. Students participated in a survey of weight-related concerns and weight-control behaviors, as well. Mixed-effects regression models were used to test for differences in weight-related concerns and weight-control behaviors across key factors of interest (i.e., weight status, gender, grade level, and SES. Results The combined prevalence of obesity and overweight was 16.6%, overall. Controlling one's weight was important to overweight and non-overweight youth, alike (94.2% v. 84.8%, p p Conclusions Interventions to promote healthy weight control should be pertinent to and well-received by school-going youth in India. Healthy weight control practices need to be explicitly encouraged and unhealthy practices reduced. Future interventions should address issues specific to body image, too, as body dissatisfaction was not uncommon among youth.

    Recent research indicates that mindfulness-based interventions are effective for stress, maladaptive weight-related behaviors, and weight loss. Little is presently known about their applicability and effectiveness when delivered electronically, including through Web-based and mobile device media. The primary aims of this review were to identify what types of electronic mindfulness-based interventions have been undertaken for stress, maladaptive weight-related behaviors, and weight loss, and to assess their overall effectiveness. A systematic search of PubMed (MEDLINE), Embase, CINAHL, and Web of Science databases was undertaken in June 2016. A total of 21 studies were identified that met inclusion criteria and were selected in the final review. Of these, 19 were mindfulness-based interventions for stress reduction. Two were Web-based mindful eating/intuitive eating interventions for weight. Only one electronic mindfulness-based study was identified that targeted both stress and maladaptive weight-related behaviors. Most electronic interventions were effective for stress reduction N = 14/19 (74%). There were insufficient electronic mindfulness-based interventions for weight to determine if they were effective or not. Additionally, no mobile mindfulness-based intervention was identified for weight or weight-related behaviors. Electronic mindfulness-based interventions through diverse media appear to be effective for stress reduction. More studies are needed that target weight and weight-related behaviors as well as studies that target both stress and weight. More randomized controlled trials (RCTs) that assess mobile mindfulness-based apps are needed as we only identified four app trials for stress. Mobile mindfulness-based interventions for weight and weight-related behaviors are a future area of research novelty.

    This is an observational study aimed to investigate the activity of autonomic nervous system during sleep in patients with sleep-related migraine. Eight consecutive migraineurs without aura were enrolled (6 women and 2 men), aged 30 to 62 years (mean 48.1 ± 9.3 years). Inclusion criteria were: high frequency of attacks (> 5 per month) and occurrence of more than 75% of the attacks during sleep causing an awakening. Patients were compared with a control group of 55 healthy subjects (23 men and 32 women, mean age 54.2 ± 13.0 years), and with a further control group of 8 age- and gender-matched healthy controls. Patient and controls underwent polysomnography and heart rate variability analysis. A significant reduction of the LF/HF ratio during N2 and N3 sleep stages was observed in migraineurs compared with controls. No differences in sleep macrostructure were observed; cyclic alternating pattern (CAP) time and CAP rate were lower in migraineurs than in controls. These findings indicate a peculiar modification of the autonomic balance during sleep in sleep-related migraine. The reduction of LF/HF ratio in NREM sleep was observed in controls, but it was quantitatively much more evident in migraineurs. Changes in LF/HF could be consequent to an autonomic unbalance which could manifest selectively (or alternatively become more evident) during sleep. These findings, together with the reduction in CAP rate, could be an expression of reduced arousability during sleep in patients with sleep-related migraine. The simultaneous involvement of the autonomic, arousal, and pain systems might suggest involvement of the hypothalamic pathways.

    This study examined how exposure to pictures of women with different body sizes (thin, obese), physical attractiveness levels (attractive, unattractive), along with exposure to weight-related messages (pro-anorexia, anti-anorexia) embedded in a fashion website affected female participants' planned behavior toward weight loss. Participants exposed to attractive model pictures showed higher intentions, attitudes, and subjective norms to lose weight compared with unattractive models. Additionally, participants exposed to thin and attractive model pictures indicated the highest attitudes and self-efficacy to lose weight, whereas those exposed to thin and unattractive model pictures indicated the lowest. Furthermore, weight-related messages moderated the effect of model appearance (body size and attractiveness) on controllability of weight-loss activities. However, website pictures' body size differences had no main effects on planned behavior toward weight loss. These effects are discussed in the light of social comparison mechanisms.

    In the United States, racial/ethnic inequalities in obesity are well-documented, particularly among women. Using the Chicago Community Adult Health Study, a probability-based sample in 2001–2003 (N=3,105), we examined the roles of discrimination and vigilance in racial inequalities in two weight-related measures, body mass index (BMI) and waist circumference (WC), viewed through a cultural racism lens. Cultural racism creates a social environment in which Black Americans bear the stigma burden of their racial group while White Americans are allowed to view themselves as individuals. We propose that in this context, interpersonal discrimination holds a different meaning for Blacks and Whites, while vigilance captures the coping style for Blacks who carry the stigma burden of the racial group. By placing discrimination and vigilance within the context of cultural racism, we operationalize existing survey measures and utilize statistical models to clarify the ambiguous associations between discrimination and weight-related inequalities in the extant literature. Multivariate models were estimated for BMI and WC separately and were stratified by gender. Black women had higher mean BMI and WC than any other group, as well as highest levels of vigilance. White women did not show an association between vigilance and WC but did show a strong positive association between discrimination and WC. Conversely, Black women displayed an association between vigilance and WC, but not between discrimination and WC. These results demonstrate that vigilance and discrimination may hold different meanings for obesity by ethnoracial group that are concealed when all women are examined together and viewed without considering a cultural racism lens.

    Many epidemiologic studies, with a good methodology, support the evidence of the positive role of regular physical activity on primary and tertiary prevention of breast cancer on the risk of recurrence and mortality. This relation depends on the level of total energy expenditure by week, which helps balance weight on lifetime, an essential part of benefit. The beneficial effects of physical activity are linked to many interrelated additional mechanisms: in a short-term, contraction of skeletal muscles involves aerobic metabolism which utilizes glucose and amino acids like glutamine, improves insulin sensitivity and lowers plasma insulin; in a long-term, physical activity produces favorable changes in body composition, decreasing body fat and increasing lean mass. That is a key point to reduce the intake of energy substrates stimulating carcinogenesis, to improve insulin sensitivity, to change the ratio of leptin and adiponectin, to enhance cellular immunity and to block cellular pathways of cell proliferation and angiogenesis. Maintaining a healthy weight through regular physical activity well balanced with energy intake is it a goal for prevention of breast cancer. Copyright © 2013 Elsevier Masson SAS.

    Full Text Available Background: Weight regain after weight loss is a common problem for all those obese or overweight who have had a recent weight loss. Different cures such as diet therapy, behavioral therapy, exercise or a mixture of them have been advised as solutions. The purpose of this review is to find the best diet or eating pattern to maintain a recent weight loss. Materials and Methods: We searched in PubMed and SCOPUS by using the following key words: Overweight, obesity, weight maintenance, weight regain, and diet therapy. Finally, we assessed 26 articles in the present article. Results: Meal replacement, low carbohydrate-low glycemic index (GI diet, high protein intake, and moderate fat consumption have shown some positive effects on weight maintenance. However, the results are controversial. A Dietary Approach to Stop Hypertension (DASH-type diet seems helpful for weight maintenance although the need for more study has remained. Some special behaviors were associated with less weight regain, such as, not being awake late at night, drinking lower amount of sugar-sweetened beverages, and following a healthy pattern. Some special foods have been suggested for weight maintenance. However, the roles of specific foods are not confirmed. Conclusion: Healthy diets recommend low carbohydrate, low GI, and moderate fat foods, but it is not clear whether they are useful in preventing weight gain. It seems that consuming fewer calories helps people to keep weight loss. Further research to find strategies in obesity management focusing on successful maintenance of weight loss is needed.

    High levels of weight suppression have been associated with greater binge eating and weight gain as well as poorer treatment outcome in bulimia nervosa. This study examined the relationship between weight suppression and bulimia nervosa symptoms and explored how weight suppression might interact with body mass index (BMI) in accounting for level of symptomatology at presentation for treatment. Participants were 64 women with threshold or sub-threshold bulimia nervosa. A clinical interview assessed binge eating and purging. Weight suppression and the interaction between BMI and weight suppression predicted frequency of binge eating such that participants with low BMI and high weight suppression engaged in the most binge eating. High levels of weight suppression also predicted more frequent purging. Additional research is warranted to examine mediators of these relationships. Copyright © 2010 Wiley Periodicals, Inc.

    To compare weight concerns and self-reported body mass index (BMI) of low birth weight (LBW) adolescent boys to those of a normative sample and examine relationships among BMI, weight concerns, self-esteem, and depression in the LBW cohort. LBW boys (n = 260; mean age, 16.0) belong to the Neonatal Brain Hemorrhage Study birth cohort. Normative boys (n = 305; mean age, 16.5) belong to the National Health and Nutrition Examination Survey. Both samples were assessed in 2001-2004 with self-report questionnaires. BMI was calculated from self-reported height and weight. Weight perception and weight dissatisfaction were assessed with the Eating Symptoms Inventory. In LBW boys, self-esteem was measured with the Rosenberg Self-Esteem Scale and depression with the Beck Depression Inventory. Based on self-reported height and weight, LBW boys were more likely to be healthy weight or underweight and less likely to be overweight than normative boys. Despite having healthier self-reported BMIs, LBW boys reported more weight concerns than the normative sample. A total of 46.9% of LBW boys perceived their weight as abnormal, and 76.5% desired weight change. Weight concerns in LBW boys mostly reflected a perception of being underweight (31.2% of the cohort) and a desire to gain weight (47.5% of the cohort), although only 6.5% were clinically underweight. Weight concerns, but not BMI, were related to clinical depression and lower self-esteem. LBW adolescent boys are at high risk of experiencing weight concerns. Weight concerns rather than BMI are associated with emotional problems in LBW boys.

    Full Text Available Aim: In Korea, obesity is more prevalent among men and lower socioeconomic groups. To explain this obesity disparity, we compared weight perception and weight control behavior across gender and socioeconomic status (SES. Methods: We analyzed data from 16,260 participants aged 20 years or older in a nationally representative cross-sectional survey. SES indicators included education and income levels. Weight under-perception was defined when participants considered themselves lighter than their measured BMI status. Either no active or inappropriate weight control (i.e., trying to gain weight in obese individuals was considered to be unhealthy patterns. Multivariate prevalence ratios were calculated using log-binomial regressions. Results: Men had a higher prevalence of weight under-perception (24.5 vs. 11.9% and unhealthy patterns of weight control behavior (57 vs. 40% than women. Low education level was associated with weight under-perception (ptrend = 0.022 in men, ptrend trend trend = 0.047 in men, ptrend Conclusion: Weight perception and weight control behavior significantly varied by gender and SES. Public actions should be directed toward improving perception and behavior of high-risk populations.

    Obesity is associated with abnormal cardiac regulation by the autonomic nervous system (ANS), this being reversed by weight loss. Bariatric (weight-reduction) surgery can induce substantial long-term weight reductions. This study compares the acute influence on ANS control of two different types of bariatric surgery involving laparascopic and open procedures. To distinguish between the cardiac influences of surgery and obesity, we perform the same analysis for laparascopic surgery in non-obese patients. Eight morbidly obese and five non-obese patients underwent surgery. Obese patients received either laparoscopic procedures (group A: n = 5, BMI = 44.3 ± 2.7 kg m 2 ) or open procedures (group B: n = 3, BMI = 55.2 ± 4.5 kg m 2 ) and non-obese patients received a laparoscopic procedure (group C: n = 5, BMI = 30.8 ± 5.8 kg m −2 ). Holter ECG was recorded and heart rate variability (HRV) was quantified together with measures of complexity (sample entropy) and structure (Hurst coefficient, scaling coefficient) of the heart rate data. Multifractal characteristics of heart rate data, not previously reported for obese patients, are also quantified and interpreted. Mixed model ANOVA was used to assess the magnitudes of each quantified variable, with surgical group and perioperative time as main factors. HRV measures were influenced only during anaesthesia (LFn increase: p = 0.009; HFn decrease: p = 0.033) and did not discriminate between patient groups. Multifractality was the only characteristic of heart rate data that discriminated between patient groups, being significantly (p < 0.001) greater in non-obese (group C) compared with obese patients (groups A and B, who had similar multifractal properties). Multifractality was also enhanced during anaesthesia (p = 0.028) but did not differ for other stages. We conclude that obesity per se rather than response to surgery is the cause of reduced multifractality. Reduced multifractality in obesity might reflect a diminished

    Full Text Available ABSTRACT There are studies on electrocardiogram (ECG in several breeds of horses, which highlights the growing importance of cardiology in this species. But few authors have addressed the influence of pregnancy on the cardiac physiology of the mare, and specifically, there are no studies on the Mini-horse breed, as well as no correlation of body weight (BW and heart rate (HR with electrocardiographic parameters in this breed. The aims of this study were to determine the effects of pregnancy on ECG parameters and to examine the relationships between these variables and body weight (BW and heart rate (HR. A total of 203 animals were used, including 143 females (66 pregnant and 60 males. Electrocardiographic examinations were performed by computerized electrocardiogram (TEB, and the parameters were evaluated in six leads in the frontal plane (Lead I, II, III, aVR, aVL and aVF and base-apex (BA. BW was inversely proportional to HR, which in turn showed an inverse relationship with the duration of the P-wave and the PR and QT intervals. The P-wave amplitude (lead II was higher in pregnant animals than in non-pregnant animals. The effect of reproductive status should be monitored by ECG throughout the entire gestational period. The 66 pregnant mares in this study were examined during the first third of their pregnancies, thus, few differences were observed between pregnant and non-pregnant animals.

    In this article, alternative methodologies for recalibration of the diagnosis-related group (DRG) weights are examined. Based on 1984 data, cost and charge-based weights are less congruent than those calculated with 1981 data. Previous studies using 1981 data demonstrated that cost- and charge-based weights were not very different. Charge weights result in higher payments to surgical DRGs and lower payments to medical DRGs, relative to cost weights.

    Full Text Available Kawasaki syndrome is an acute systemic vasculitis of unknown etiology, which mainly affects children within the first 5 years of fife. At the present time, Kawasaki syndrome is recognized to be a leading cause of acquired organic heart diseases in children, which may result in coronary heart disease, myocardial infarction, and sudden death in children and young people. Most complications are associated with the cardiovascular system, with coronary artery changes in particular. Transthoracic echocardiography, which, besides coronary artery assessment, makes it possible to evaluate right and left ventricular systolic and diastolic functions and to study the cardiac valves and changes in pericardial effusion, is a major technique in Kawasaki syndrome. The paper outlines an update on the epidemiology, etiology, pathogenetic mechanisms, and pathomorphology of Kawasaki syndrome and considers possible coronary and noncoronary changes, outcomes, and clinical manifestations.

    This study examined associations between mothers' depressive symptoms and parenting behaviors related to children's nutrition and physical activity. Data from the Early Childhood Longitudinal Study-Birth Cohort, a nationally representative study of children from infancy through kindergarten entry. Contemporaneous and lagged associations between maternal depressive symptoms and mothers' parenting behaviors were tested, controlling for background characteristics. The mediating effect of use of a physician's office or clinic as a source for routine care was tested. At each wave, between 18 and 20 % of mothers were considered as having moderate or severe depressive symptoms. These mothers were 1.3 percentage points more likely to put their infants to bed with a bottle, 2.6 percentage points less likely to have rules about the foods their children eat, and their children were 3.0 percentage points less likely to be in bed by 9:00 p.m. than mothers lacking depressive symptoms. These mothers also reported that their families ate dinner together fewer nights per week, and their children watched more television per day, than non-depressed mothers. The use of a physician's office or clinic partially mediated associations between maternal depressive symptoms and whether infants went to bed with a bottle. Interventions that identify maternal depression early may be useful in promoting healthy parenting behaviors and weight outcomes among young children.

    Full Text Available Objective: to evaluate the relationship between body composition of preschool children suffering from excess weight and birth weight (BW. Methods: probabilistic sample, by conglomerates, with 17 daycare centers (of a total of 59 composing a final sample of 479 children. We used Z-score of Body Mass Index (zBMI ≥ +1 and ≥ +2, respectively, to identify preschool children with risk of overweight and excess weight (overweight or obesity. The arm muscle area (AMA and the arm fat area (AFA were estimated from measurements of arm circumference, triceps skin fold thickness. Results: the prevalence of risk of overweight was 22.9% (n=110 and excess weight was 9.3% (n=44. The risk of overweight and excess weight in children did not show correlation between BW and AFA, but it did with adjusted arm muscle area (AMAa (rp= 0.21; p= 0.0107. The analysis of the group with excess weight alone also showed a positive correlation between BW and AMAa (rp= 0.42; p= 0.0047. Conclusion: among overweight children, lower BW is associated with a lower arm muscle area in early preschool age, regardless of the fat arm area presented by them.

    This umbrella review analysed the relationships between family variables and child/adolescent body weight, diet and physical activity. In line with theories of health behaviour change, it was assumed that behaviour-specific family variables (i.e. beliefs, perceptions and practices referring to food intake or physical activity) would have stronger support than more general family variables (i.e. socio-economic status or general parental practices). Data obtained from 18 systematic reviews (examining 375 quantitative studies) were analysed. Reviews of experimental trials generally supported the effectiveness of reward/positive reinforcement parental strategies, parental involvement in treatment or prevention programmes, and cognitive-behavioural treatment in reducing child/adolescent body mass and/or obesity. Results across reviews of correlational studies indicated that healthy nutrition of children/adolescents was related to only one parental practice (parental monitoring), but was associated with several behaviour-specific family variables (e.g. a lack of restrictive control over food choices, high intake of healthy foods and low intake of unhealthy foods by parents and siblings, low pressure to consume foods). With regard to adolescent physical activity, stronger support was also found for behaviour-specific variables (e.g. physical activity of siblings), and for certain socio-economic variables (e.g. parental education). Child and adolescent obesity prevention programmes should account for behaviour-specific family variables. © 2011 Blackwell Publishing Ltd.

    Weight-based teasing is common among youth, but little is known about its long-term impact on health outcomes. We aimed to 1) identify whether weight-based teasing in adolescence predicts adverse eating and weight-related outcomes 15years later; and 2) determine whether teasing source (peers or family) affects these outcomes. Data were collected from Project EAT-IV (Eating and Activity in Teens and Young Adults) (N=1830), a longitudinal cohort study that followed a diverse sample of adolescents from 1999 (baseline) to 2015 (follow-up). Weight-based teasing at baseline was examined as a predictor of weight status, binge eating, dieting, eating as a coping strategy, unhealthy weight control, and body image at 15-year follow-up. After adjusting for demographic covariates and baseline body mass index (BMI), weight-based teasing in adolescence predicted higher BMI and obesity 15years later. For women, these longitudinal associations occurred across peer and family-based teasing sources, but for men, only peer-based teasing predicted higher BMI. The same pattern emerged for adverse eating outcomes; weight-based teasing from peers and family during adolescence predicted binge eating, unhealthy weight control, eating to cope, poor body image, and recent dieting in women 15years later. For men, teasing had fewer longitudinal associations. Taken together, this study shows that weight-based teasing in adolescence predicts obesity and adverse eating behaviors well into adulthood, with differences across gender and teasing source. Findings underscore the importance of addressing weight-based teasing in educational and health initiatives, and including the family environment as a target of anti-bullying intervention, especially for girls.

    2015-01-01

    We developed a novel decision-making paradigm that allows us to apply prospect theory in behavioral economics to body mass. 67 healthy young adults completed self-report measures and two decision-making tasks for weight-loss, as well as for monetary rewards. We estimated risk-related preference and loss aversion parameters for each individual, separately for weight-loss and monetary rewards choice data. Risk-seeking tendency for weight-loss was positively correlated with body mass index in individuals who desired to lose body weight, whereas the risk-seeking for momentary rewards was not. Risk-seeking for weight-loss was correlated to excessive body shape preoccupations, while aversion to weight-gain was correlated with self-reports of behavioral involvement for successful weight-loss. We demonstrated that prospect theory can be useful in explaining the decision-making process related to body mass. Applying prospect theory is expected to advance our understanding of decision-making mechanisms in obesity, which might prove helpful for improving healthy choices.

    In the US population of 300 million, 3 million have heart failure with reduced ejection fraction and 300,000 have advanced heart failure. Long-term mechanical circulatory support will, within the next decade, be recommended to 30,000 patients annually in the USA, 3000 undergo heart transplantation annually. What do these advances mean for persons suffering from advanced heart failure and their loved ones/caregivers? In this perspective article, we discuss - by exemplifying a case report of a 27-year-old man receiving a Total Artificial Heart - a practice concept of modern medicine that fully incorporates the patient's personhood perspective which we have termed Relational Medicine™. From this case study, it becomes apparent that the successful practice of modern cardiovascular medicine requires the person-person encounter as a core practice element.

    This paper aims to describe the prevalence of parent-adolescent conversations about eating, physical activity and weight across sociodemographic characteristics and to examine associations with adolescent BMI, dietary intake, physical activity and sedentary behaviors. Data from two linked epidemiological studies were used for cross-sectional analysis. Parents (n=3,424; 62% females) and adolescents (n=2,182; 53.2% girls) were socioeconomically and racially/ethnically diverse. Fathers reported more parent-adolescent conversations about healthful eating and physical activity with their sons and mothers reported more weight-focused conversations with their daughters. Parents of Hispanic/Latino and Asian/Hmong youth and parents from lower SES categories engaged in more conversations about weight and size. Adolescents whose mothers or fathers had weight-focused conversations with them had higher BMI percentiles. Adolescents who had two parents engaging in weight-related conversations had higher BMI percentiles. Healthcare providers may want to talk about the types of weight-related conversations parents are having with their adolescents and emphasize avoiding conversations about weight specifically.

    Examine whether unhealthy and extreme weight control behaviors (WCBs) mediate the relationship between youth weight status and disease-specific health-related quality of life (HRQOL) in treatment-seeking youth who are overweight and obese (OV/OB). 82 youth 10-17 years of age who were OV/OB and attending an outpatient obesity-related medical appointment completed measures assessing unhealthy and extreme WCBs and disease-specific HRQOL. Parents completed a demographic questionnaire and medical staff measured youth height and weight. Regression analyses revealed that unhealthy WCBs mediated the associations between youth weight status and emotional and social avoidance disease-specific HRQOL, such that higher body mass index (BMI) predicted unhealthy WCBs, which were ultimately associated with poorer emotional and social HRQOL. Mediation analyses were not significant for total, physical, teasing/marginalization, and positive attributes disease-specific HRQOL. In addition, extreme WCBs did not mediate the association between youth weight status and any subscales of the disease-specific HRQOL measure. Weight status is an important predictor of disease-specific HRQOL in OV/OB youth; however, the association with emotional and social HRQOL is partially accounted for by youth engagement in unhealthy WCBs. Clinicians and researchers should assess WCBs and further research should explore and evaluate appropriate intervention strategies to address unhealthy WCBs in pediatric weight management prevention and treatment efforts.

    Obesity may associate with greater cardiovascular risk in adults with congenital heart disease (ACHD) than in the general population. As ACHD often have exercise limitations, they may be uniquely predisposed to obesity. Nevertheless, obesity prevalence in ACHD, compared with the general population, has not been quantified in a large US cohort. Hence, we sought to determine the prevalence of obesity (30 ≤ body mass index obesity (body mass index ≥40), in a large cohort of ACHD, compared with matched controls. Retrospective analysis was thus performed on all ACHD seen in an academic system in 2013. CHD severity was classified as simple, complex, or unclassified, using recently published criteria. A control group without CHD was randomly generated matching for age, gender, and race/ethnicity; 1,451 ACHD met inclusion criteria; 59.5% of ACHD were overweight to morbidly obese. Compared with controls, ACHD had similar prevalence of overweight (odds ratio [OR] 1.04, 95% confidence interval [CI] 0.89 to 1.22, p = 0.63) and obesity (OR 0.96, 95% CI 0.81 to 1.15, p = 0.69) but lower prevalence of morbid obesity (OR 0.24, 95% CI 0.16 to 0.34, p obese. This is the largest study of obesity in US ACHD and the highest reported obesity prevalence in ACHD to date. As obesity is associated with significant cardiovascular risk, our findings indicate a need for improved lifestyle counseling in patients with CHD of all ages. Copyright © 2016 Elsevier Inc.

    Aims and Objectives It is a known fact that weight of upper limb is transmitted to the axial skeleton through clavicle. The present study is an attempt to correlate pattern of compact and trabecular bone of clavicle as a weight transmitting bone. Materials and Methods Sixty clavicles were studied from right and left sides of 30 cadavers donated to the Anatomy department, Pramukhswami Medical College, Karamsad, India. The study was focused on the thickness of compact bone of clavicle and trabecular pattern of this bone. Results Cancellous bone: Cancellous bone near both ends of clavicle presented meshwork of thin bony plates. Between the conoid tubercle and area for attachment of costo-clavicular ligament, cancellous bone showed a definite pattern. Thickness of compact bone The compact bone was thicker between conoid tubercle and area for attachment of costo-clavicular ligament. At midshaft point thickness of compact bone was maximum. Conclusion The structure of clavicle between conoid tubercle and area for costoclavicular ligament showed thick compact bone and definite pattern of cancellous bone. This structure of clavicle between conoid tubercle and area for attachment of costo-clavicular ligament transmits weight from lateral to medial direction and this knowledge of clavicular structure will also be useful to orthopedic surgeons to deal with clavicular fractures and other abnormalities.

    Concern about post-cessation weight gain is a barrier to making attempts to quit smoking; however, its effect on smoking cessation is unclear. In this study we examine cessation-related weight concern among the homeless, which hasn't been studied. Homeless males (n = 320) and females (n = 110) participating in a smoking cessation RCT in the Twin Cities, Minnesota from 2009 to 2011 completed surveys on cessation-related weight concern, smoking status, and components from the Behavioral Model for Vulnerable Populations. Generalized estimating equations were used to examine baseline predictors of cessation-related weight concern at baseline, the end of treatment, and 26-weeks follow-up. Logistic regression models were used to examine the relationship between cessation-related weight concern and smoking status at the end of treatment and follow-up. Females had higher cessation-related weight concern than males. Among males, older age, Black race, higher BMI, depression, and having health insurance were associated with higher cessation-related weight concern. Among females, nicotine dependence, greater cigarette consumption, indicating quitting is more important, older age of smoking initiation, and less support to quit from family were associated with higher cessation-related weight concern. In multivariate analyses, cessation-related weight concern decreased over time among females. Cessation-related weight concern wasn't associated with smoking cessation. Although several types of characteristics predicted cessation-related weight concern among males, only smoking characteristics predicted cessation-related weight concern among females. Given the small proportion of quitters in this study (8% of males and 5% of females), further research on the impact of cessation-related weight concern on smoking cessation among the homeless is warranted.

    Chronic paediatric heart disease is often associated with residual symptoms, persisting functional restrictions, and late sequelae for psychosocial development. It is, therefore, increasingly important to evaluate the health-related quality of life of children and adolescents with chronic heart disease. The aim of this study was to determine medical and socio-demographic variables affecting health-related quality of life in school-aged children and adolescents with chronic heart disease. Patients and methods The Pediatric Cardiac Quality of Life Inventory was administered to 375 children and adolescents and 386 parental caregivers. Medical information was obtained from the charts. The socio-demographic information was provided by the patients and caregivers. Greater disease severity, low school attendance, current cardiac medication, current parental employment, uncertain or limited prognosis, history of connection to a heart-lung machine, number of nights spent in a hospital, and need for treatment in a paediatric aftercare clinic independently contributed to lower health-related quality of life (self-report: R2=0.41; proxy-report: R2=0.46). High correlations between self-reports and parent-proxy reports indicated concordance regarding the evaluation of a child's health-related quality of life. Beyond medical treatment, integration into school is important to increase health-related quality of life in children and adolescents surviving with chronic heart disease. Regular screening of health-related quality of life is recommended to identify patients with special needs.

    Primary care is ideally placed to play an effective role in patient weight management; however, patient weight is seldom discussed in this context. A synthesis of studies that directly observe weight discussion in primary care is required to more comprehensively understand and improve primary care weight-related communication. To systematically identify and examine primary care observational research that investigates weight-related communication and its relationship to patient weight outcomes. A systematic review of literature published up to August 2015, using seven electronic databases (including MEDLINE, Scopus and PsycINFO), was conducted using search terms such as overweight, obese and/or doctor-patient communication. Twenty papers were included in the final review. Communication analysis focused predominantly on 'practitioner' use of specific patient-centred communication. Practitioner use of motivational interviewing was associated with improved patient weight-related outcomes, including patient weight loss and increased patient readiness to lose weight; however, few studies measured patient weight-related outcomes. Studies directly observing weight-related communication in primary care are scarce and limited by a lack of focus on patient communication and patient weight-related outcomes. Future research should measure practitioner and patient communications during weight discussion and their impact on patient weight-related outcomes. This knowledge may inform the development of a communication intervention to assist practitioners to more effectively discuss weight with their overweight and/or obese patients. © The Author 2016.

    Individuals born at low or high birth weight (BW) have elevated adiposity. The extent to which physical activity can mitigate this risk is unknown. The aim of this study was to determine if associations between BW and adiposity vary by self-reported moderate-to-vigorous physical activity (MVPA) among adolescents. We used data on adolescents in the National Health and Nutrition Examination Survey (1999-2006; 12-15 years; n = 4064). Using gender-stratified linear regression, we modelled body mass index (BMI) and waist circumference (WC) z-scores as a function of low, normal and high BW, MVPA (weekly Metabolic Equivalent of Task hours) and MVPA*BW cross-product terms, adjusting for sociodemographics, diet and, in WC models, BMI. Among girls with low MVPA, those born with high BW had greater BMI than normal BW; this difference diminished with greater MVPA (coefficient [95% confidence interval]: low MVPA: 0.72 [0.29, 1.14]; high MVPA: -0.04 [-0.48, 0.39]; P for interaction = 0.05). Among boys, MVPA did not modify the associations between BW and BMI. WC was unrelated to BW, regardless of MVPA. Findings suggest that effects of high BW in total adiposity can be more easily modified with MVPA in adolescent girls than in boys. © 2015 World Obesity.

    Full Text Available In order to assess the relative influence of age, resting heart rate (HR and sedentary life style, heart rate variability (HRV was studied in two different groups. The young group (YG consisted of 9 sedentary subjects aged 15 to 20 years (YG-S and of 9 nonsedentary volunteers (YG-NS also aged 15 to 20. The elderly sedentary group (ESG consisted of 16 sedentary subjects aged 39 to 82 years. HRV was assessed using a short-term procedure (5 min. R-R variability was calculated in the time-domain by means of the root mean square successive differences. Frequency-domain HRV was evaluated by power spectrum analysis considering high frequency and low frequency bands. In the YG the effort tolerance was ranked in a bicycle stress test. HR was similar for both groups while ESG showed a reduced HRV compared with YG. Within each group, HRV displayed a negative correlation with HR. Although YG-NS had better effort tolerance than YG-S, their HR and HRV were not significantly different. We conclude that HRV is reduced with increasing HR or age, regardless of life style. The results obtained in our short-term study agree with others of longer duration by showing that age and HR are the main determinants of HRV. Our results do not support the idea that changes in HRV are related to regular physical activity.

    In order to assess the relative influence of age, resting heart rate (HR) and sedentary life style, heart rate variability (HRV) was studied in two different groups. The young group (YG) consisted of 9 sedentary subjects aged 15 to 20 years (YG-S) and of 9 nonsedentary volunteers (YG-NS) also aged 15 to 20. The elderly sedentary group (ESG) consisted of 16 sedentary subjects aged 39 to 82 years. HRV was assessed using a short-term procedure (5 min). R-R variability was calculated in the time-domain by means of the root mean square successive differences. Frequency-domain HRV was evaluated by power spectrum analysis considering high frequency and low frequency bands. In the YG the effort tolerance was ranked in a bicycle stress test. HR was similar for both groups while ESG showed a reduced HRV compared with YG. Within each group, HRV displayed a negative correlation with HR.

    Currently preterm births are the leading causes of newborn deaths and newborn mortality in developed countries. Infants born prematurely remain vulnerable to many acute complications and long-term disabilities. There is a growing concern surrounding the moral and ethical implications of the complex and technological care being provided to extremely low birth weight infants in neonatal intensive care units in the developed nations. The purpose of this study was to describe the ethical and moral issues that neonatal intensive care nurses experience when caring for low birth weight preterm infants and their families. A phenomenological method design was used to describe the lived experiences of nurses with ethical and moral issues encountered in the neonatal intensive care unit. One-on-one, semi-structured interviews using open-ended questions were used to gather data from the participants. The setting for this study was a 97-bed neonatal intensive care. A total of 16 female nurses were interviewed. Approval to conduct the research study was obtained from the institutional review board of the hospital where the study was conducted. Formal signed consent was obtained from each participant. To ensure confidentiality, each participant was asked to choose a confederate name to be used in the interview and the transcriptions. The thematic analysis identified five recurring themes: (a) at the edge of viability, (b) infant pain and discomfort, (c) crucial decisions, (d) communicating with parents, and (e) letting go. Neonatal intensive care unit nurses indicated that they often had challenges to their own sense of morality as they struggled to protect the infant from pain and unnecessary discomfort, provide care to an infant and their family whom they thought was faced with a lifetime of challenges and poor health, accepting decisions made by parents, and feeling as if parents were not adequately informed about outcomes. © The Author(s) 2014.

    Full Text Available Abstract Background Associations between hours worked per week and Body Mass Index (BMI, food intake, physical activity, and perceptions of eating healthy at work were examined in a sample of transit workers. Methods Survey data were collected from 1086 transit workers. Participants reported hours worked per week, food choices, leisure-time physical activity and perceptions of the work environment with regard to healthy eating. Height and weight were measured for each participant. Multivariate linear and logistic regressions were conducted to examine associations between work hours and behavioral variables. Associations were examined in the full sample and stratified by gender. Results Transit workers working in the highest work hour categories had higher BMI and poorer dietary habits, with results differing by gender. Working 50 or more hours per week was associated with higher BMI among men but not women. Additionally, working 50 or more hours per week was significantly associated with higher frequency of accessing cold beverage, cold food, and snack vending machines among men. Working 40 or more hours per week was associated with higher frequency of accessing cold food vending machines among women. Reported frequency of fruit and vegetable intake was highest among women working 50 or more hours per week. Intake of sweets, sugar sweetened beverages, and fast food did not vary with work hours in men or women. Physical activity and perception of ease of eating healthy at work were not associated with work hours in men or women. Conclusions Long work hours were associated with more frequent use of garage vending machines and higher BMI in transit workers, with associations found primarily among men. Long work hours may increase dependence upon food availability at the worksite, which highlights the importance of availability of healthy food choices.

    2004-01-01

    Thirst is a frequent and stressful symptom experienced by hemodialysis patients. Several studies have noted a positive relationship between thirst and interdialytic weight gain (IDWG). These factors prompted us to consider ways that we could intervene to reduce thirst and IDWG through an educative, supportive nursing intervention. This paper presents the results of a pilot research project, the purpose of which was to: examine the relationship between thirst distress (the negative symptoms associated with thirst) and IDWG in a sample of our patients, describe patients' strategies for management of thirst, and establish the necessary sample size for the planned intervention study. The pilot research project results showed that in a small sample of 20, there was a mildly positive, though not statistically significant, correlation between thirst distress and IDWG (r = 0.117). Subjects shared a wide variety of thirst management strategies including: limiting salt intake, using ice chips, measuring daily allotment, performing mouth care, eating raw fruits and vegetables, sucking on hard candy and chewing gum. This pilot research project showed that given an alpha of 0.05 and a power of 80%, we will require a sample of 39 subjects to detect a 20% change in IDWG. We will employ these results to plan our intervention study, first by establishing the appropriate sample size and second by incorporating identified patient strategies into an educational pamphlet that will form the basis of our intervention.

    2016-08-01

    Full Text Available Age-related cardiomyopathy accounts for a significant part of heart failure cases. Imbalance of the energetic equilibrium of the heart along with mitochondrial dysfunction and impaired β-adrenergic receptor signaling contributes in the aggravation of cardiac function in the elderly. In this review article, studies that correlate cardiac aging with lipotoxicity are summarized. The involvement of inhibition of peroxisome proliferator-activated receptor-α, β-adrenergic receptor desensitization, and mitochondrial dysfunction as underlying mechanisms for the lipid-driven age-related cardiomyopathy are presented with the aim to indicate potential therapeutic targets for cardiac aging.

    Considerable research on preventive health care behaviors has been conducted in different segments of the population. Although nurses are the largest group of direct health care providers (3 million), little is known about their preventive health care behaviors. As the average age of nurses working in the United States (US) increases (mean age 47 years), maintaining their health to ensure they can continue to provide optimal health care to others becomes a greater priority. This descriptive online study examined registered nurses' dietary and exercise practices, weight status, stress levels, and preferred preventive health strategies using a sample of nurses recruited from a community-based, urban teaching hospital (n = 183; mean age 47 ± 11.3 years). The majority of participants (72.2%, n = 122) reported a lack of exercise, and more than half (53.8%, n = 91) had an irregular meal pattern. The average body mass index (BMI) was 28.3 ± 6.8, and 59.2% (n = 100) were either overweight (n = 47) or obese (n = 53). BMI had a significant inverse relationship with having a regular meal schedule and the amount of time spent exercising. Participants who reported greater stress had more irregular meal schedules. The most frequently used stress-release method was eating (n = 32), followed by exercise (n = 31). Nurses are fully aware of measures that should be taken for healthy living. Their knowledge, however, has not been well translated into their own self-care. As nursing shortages loom, maintaining the health of the aging nursing workforce is essential to retention. Further research is needed to identify factors that may motivate nurses to better care for themselves and measures that can be implemented by employers to initiate and sustain these preventive health care behaviors.

    Full Text Available Background The relationship between baldness and heart disease is still controversial. We performed an updated meta-analysis of observational studies to evaluate the relation between heart disease and androgenic alopecia or alopecia areata. Aims To evaluate the relation between heart disease and androgenic alopecia or alopecia areata. Methods Studies were identified by searching Medline and Embase up to October 20, 2017 without language restriction. Metaanalysis was performed by using a random-effects model. Results Nine studies were included in the meta-analysis (eight on androgenic alopecia and one on alopecia areata: 44,806 participants. Compared to men without baldness, men with androgenic alopecia had an increased risk of heart disease (relative risk (RR: 1.32, 95 per cent CI: 1.08 to 1.63, p=0.01, I2 =25 per cent, and younger men (<55 or ≤60 years showed a stronger association (RR: 1.44, 95 per cent CI: 1.11 to 1.86, p=0.01, I2 =0 per cent. The positive relation depended on the severity of baldness and decreased in order of severe vertex (RR: 1.60, 95 per cent CI: 1.19 to 2.16, p=0.002, moderate vertex (RR: 1.41, 95 per cent CI: 1.22 to 1.64, p<0.001, mild vertex (RR: 1.18, 95 per cent CI: 1.05 to 1.33, p=0.007, and frontal baldness (RR: 1.10, 95 per cent CI: 0.92 to 1.32, p=0.28. In contrast, there was no significant relation between alopecia areata and heart disease (RR: 0.91, 95 per cent CI: 0.60 to 1.39, p=0.66. Conclusion Androgenic alopecia is associated with heart disease, but alopecia areata is not.

    High blood pressure (BP) is associated with reduced pain sensitivity, known as BP-related hypoalgesia. The underlying neural mechanisms remain uncertain, yet arterial baroreceptor signaling, occurring at cardiac systole, is implicated. We examined normotensives using functional neuroimaging (fMRI) and pain stimulation during distinct phases of the cardiac cycle to test the hypothesized neural mediation of baroreceptor-induced attenuation of pain. Eighteen participants (10 women; 32.7 ± 6.5 years) underwent BP monitoring over one week at home, and individual pain thresholds were determined in the lab. Subsequently, participants were administered unpredictable painful and non-painful electrocutaneous shocks (stimulus type), timed to occur either at systole or diastole (cardiac phase) in an event-related design. After each trial, participants evaluated their subjective experience. Subjective pain was lower for painful stimuli administered at systole compared to diastole, F1, 2283 = 4.82; p = 0.03. Individuals with higher baseline BP demonstrated overall lower pain perception, F1, 2164 = 10.47; p < 0.0001. Within the brain, painful stimulation activated somatosensory areas, prefrontal cortex, cingulate cortex, posterior insula, amygdala, and the thalamus. Stimuli delivered during systole (concurrent with baroreceptor discharge) activated areas associated with heightened parasympathetic drive. No stimulus type x cardiac phase interaction emerged except for a small cluster located in the right parietal cortex. We confirm the negative associations between BP and pain, highlighting the antinociceptive impact of baroreceptor discharge. Neural substrates associated with baroreceptor/BP-related hypoalgesia include superior parietal lobule, precentral and lingual gyrus, regions typically involved in the cognitive aspects of pain experience.

    The Children's Eating Behaviour Questionnaire (CEBQ) is a multi-dimensional, parent-reported questionnaire measuring children's eating behaviours related to obesity risk, i.e. 'enjoyment of food', 'food responsiveness', 'slowness in eating' and 'satiety responsiveness'. It has not previously been validated in a Swedish population, neither on children under the age of 2 years. In the present study we examined the factor structure and the reliability of the Swedish version of the CEBQ, for use in an obesity intervention programme targeting preschool children 1-6 years. Further, the associations between eating behaviours and children's age, gender and relative weight (BMI SDS) and parental weight were investigated. Parents to 174 children aged 1-6 years (50% girls, mean age 3.8 years), recruited from five kindergartens in Stockholm, completed the Swedish version of the CEBQ. Data on children's weight and height, parental weight, height and educational level was collected. Children's relative weight was calculated for a subpopulation (mean BMI SDS -0.4, n = 47). Factorial validation (Principal Component Analysis) on all CEBQ items was performed. Differences in eating behaviours by age, gender and parental weight were examined. Correlations between eating behaviours and the child's BMI SDS were analysed controlling for age, gender, parental weight and education in linear regression analyses. The factor analysis revealed a seven factor solution with good psychometric properties, similar to the original structure. The behaviour scales 'overeating'/'food responsiveness', 'enjoyment of food' and 'emotional undereating' decreased with age and 'food fussiness' increased with age. Eating behaviours did not differ between girls and boys. The children's relative weight was not related to any of the eating behaviours when controlling for age, gender, parental weight and education, and only associated with parental weight status.

    To understand the distribution of birth weight among premature infants and the associated social factors. The study population consisted of 97 537 women who delivered singleton live birth of 20 to 41 gestational weeks in 4 counties/cities, Jiangsu and Zhejiang provinces, China from 1995 to 2000. Chi-square test was employed to test the difference of proportions between respective groups. One- way ANOVA was used to test the differences regarding the mean of gestational weeks at the first prenatal visit and the mean of prenatal visits between the two groups. Multivariate logistic regression was conducted to examine the factors associated with premature birth. Women aged 35 years had higher (8.8%) premature incidence than those aged less than 24 years (5.6%), 25 - 29 years (4.6%), or 30 - 34 years (4.5%, P premature incidence than those with height taller than 150 cm (5.0%). Women whose BMI were at least 28 and 24 - 28 had higher (5.5%, 5.5%) premature incidences than those whose BMI were 18.5 - 24.0 (5.0%), premature birth was 6.0% among women without previous pregnancy, higher than that among those women with 4 times of pregnancies (5.7%), 2 times of pregnancies (4.3%), and 3 times of pregnancies (4.0%). Parous women with at least two deliveries had higher (9.3%) premature incidence than the primiparous women (5.2%) and whose women with only one delivery (4.5%, P premature incidence than those who did not receive the service (6.1%). The mean times of prenatal visits among women with premature births was 8.53, less than that of those with full term delivery (10.97). Women with less than four times of prenatal visit had higher (18.9%) premature incidence than those with at least five prenatal visits (4.9%). Multivariate logistic regression showed that premature delivery risk was associated with age, height, BMI, gravidity, parity, early prenatal care, the mean of gestational weeks at first prenatal visit and the mean number of prenatal visits etc. Premature delivery

    Greater self-regulatory behavior usage is associated with greater weight loss within behavioral weight loss treatments. Hedonic hunger (i.e., susceptibility to environmental food cues) may impede successful behavior change and weight loss. Adult men and women (N = 111, body mass index M ± SD = 35.89 ± 6.97 kg/m(2)) were assessed before and after a 15-week lifestyle change weight loss program with a partial meal-replacement diet. From pre- to post-treatment, reported weight control behavior usage improved and hedonic hunger decreased, and these changes were inversely related. Individuals with higher hedonic hunger scores at baseline showed the greatest weight loss. Similarly, participants with lower baseline use of weight control behaviors lost more weight, and increased weight control behavior usage was associated with greater weight loss-particularly among individuals with low baseline hedonic hunger. Further study is warranted regarding the significance of hedonic hunger in weight loss treatments.

    Full Text Available Background: Females are more likely than males to perceive themselves as too heavy, this has been explained in terms of the equation of “female beauty with extreme thinness.” Therefore, females are in general prone to develop unhealthy behaviors for weight management. Wrong weight control behaviors have significant health consequences. Objectives: To investigate the body weight concerns, body satisfaction, and weight control behaviors among young females and their association with age and socioeconomic status (SES. Materials and Methods: A cross-sectional study conducted in urban areas from a major city in South India. About 650 healthy unmarried females aged 15–25 years formed the study population. Self-reporting questionnaires were used to obtain relevant data. The categorical data were analyzed using Chi-square, correlation, and regression analyses by SPSS version 16. Results: Most overweight and obese subjects perceived themselves as overweight. Adolescents were more likely to report themselves as overweight. The perceived weight, body satisfaction, and weight control behaviors are influenced by weight status and age of the subjects. However, SES of the participants did not exhibit effect of others' opinion about their weight and body satisfaction as well as weight management behaviors. Conclusion: The high prevalence of weight-related concerns suggests that all females should be reached with appropriate information and interventions. Healthy weight control practices need to be explicitly promoted and unhealthy practices discouraged. Young females need special attention toward weight management.

    Low molecular weight heparins (LMWHs) are polydisperse and microheterogenous mixtures of polysaccharides used as anticoagulant drugs. Profiling analysis is important for obtaining deeper insights into the structure of LMWHs. Previous oligosaccharide mapping methods are relatively low resolution and are unable to show an entire picture of the structural complexity of LMWHs. In the current study a profiling method was developed relying on multiple heart-cutting, two-dimensional, ultrahigh performance liquid chromatography with quadruple time-of-flight mass spectrometry. This represents an efficient, automated, and robust approach for profiling LMWHs. Using size-exclusion chromatography and ion-pairing reversed-phase chromatography in a two-dimensional separation, LMW components of different sizes and LMW components of the same size but with different charges and polarities can be resolved, providing a more complete picture of a LMWH. Structural information on each component was then obtained with quadrupole time-of-flight mass spectrometry. More than 80 and 120 oligosaccharides were observed and unambiguously assigned from the LMWHs, nadroparin and enoxaparin, respectively. This method might be useful for quality control of LMWHs and as a powerful tool for heparin-related glycomics.

    We examined the reasons for weight gain and barriers to weight loss among emerging adults with obesity. Eighty-one female undergraduate students with obesity completed 4-open ended questions in 2015-2016. Qualitative responses were analyzed using NVivo 11 Pro software. Most participants experienced weight gain prior to attending college. The most commonly reported reasons for weight gain include a lack of ability to control one's behaviors or overcome barriers (ie, poor eating habits, lack of physical activity, lack of time, easy access to food), emotional/mental health issues, physical health, and influence of significant others. Nearly half reported having a weight loss goal. Most reported having used one or more weight loss methods. Few reached short-term weight loss but quickly regained the lost weight. Major reported barriers reflect a lack of self-regulation skills, negative mood and stress, and lack of self-efficacy for healthy eating or physical activity. Results suggest that the perceived ability to control one's behaviors and overcome barriers, self-efficacy, and mood are important in weight-related behaviors, weight, and weight loss success among emerging adults, especially those enrolled in college.

    Cardiovascular diseases (CVDs) have been related to low birth weight, suggesting the foetal environment may program future risk. Alternatively, common genetic factors for both low birth weight and CVD could explain such associations. We investigated associations between offspring birth weight and paternal and maternal cardiovascular mortality and offspring birth weight and cardiovascular mortality among all four grandparents, and further assessed the mediating role of maternal smoking during pregnancy. All births from 1967 to 2008 that could be linked to parents and grandparents comprised the population (n = 1,004,255). The mortality follow-up among parents was from 1970 to 2008 and among grandparents from 1960 to 2008. The association of grandparental mortality with maternal smoking during pregnancy was analysed in a subpopulation of those born after 1997 (n = 345,624). Per quintile higher in birth weight was related to 0.82 (0.75-0.89) hazard ratio from coronary heart disease in mothers and 0.94 (0.92-0.97) in fathers. For stroke, these were 0.85 (0.78-0.92) and 0.94 (0.89-1.00), respectively. In grandparents for cardiovascular causes, the effects were 0.95 (0.93-0.96) (maternal grandmother), 0.97 (0.96-0.98) (maternal grandfather), 0.96 (0.94-0.98) (paternal grandmother), and 0.98 (0.98-1.00) (paternal grandfather). Adjusting for maternal smoking in pregnancy in the subpopulation accounted for much of the effect on grandparental cardiovascular mortality in all categories of birth weight. For grandparental diabetes mortality, U-shaped associations were seen with grandchild birth weight for the maternal grandmother and inverse associations for all other grandparents. Associations between CVD mortality in all four grandparents and grandchild birth weight exist, and while genetic and environmental factors may contribute to these, it appears that there is an important role for maternal smoking during pregnancy (and associated paternal smoking) in generating these

    How weight perception influences weight-related knowledge, attitudes, and behaviors in Chinese children is unknown. We investigated self-perception of body weight and its correlates, and analyzed the relationship between weight perception and weight-related knowledge, attitudes, and behaviors in children in Guangzhou, China. We assessed self-reported weight perception, weight-related knowledge, attitudes, and behaviors in 3752 children aged 7-12 years. Underweight or overweight was defined using the Chinese criteria based on body mass index (BMI). Binary logistic regression analyses were performed to assess correlates of weight underestimation. In total, 27.3% of children underestimated and 6.7% overestimated their weight status. Weight underestimation was common among normal-weight (34.1%) and overweight children (25.3%). Older age, female sex, and child BMI z-score were negatively associated with normal-weight children's underestimation, whereas older age, paternal obesity, maternal obesity, and child BMI z-score were negatively associated with overweight children's underestimation. Correct answers on weight-related knowledge questions ranged from 81.5% to 98.6% and did not differ by weight perception within BMI categories. Although negative perceivers (i.e., those who perceived themselves as underweight or overweight) had a higher intention to change weight, they behaved more unhealthily on fruit intake, breakfast, screen time, and daily moderate-to-vigorous physical activities time than counterparts. Weight underestimation was prevalent in normal-weight and overweight children in Guangzhou. Negative perceivers had stronger willingness to change weight but tended to behave more unhealthily on certain behaviors than positive perceivers. Childhood obesity interventions should incorporate health education and practical support to promote healthy eating and physical activity. Copyright © 2017 The Authors.

    BACKGROUND: Relative body weight is typically inversely associated with social status in affluent societies but studies comparing the social patterning of relative body weight and obesity in different countries have only seldom been conducted. The aim of this study was to analyse and compare....... Relative weight was studied by using body mass index (BMI), and those with BMI > or =30 kg/m(2) were regarded as obese. Logistic regression analysis was used to examine the social patterning of obesity in the pooled dataset. Two-variable interaction effects were tested separately. RESULTS: Compared...

    This study evaluated the feasibility of using the youth Weight, Activity, Variety, and Excess (WAVE) screener in a classroom setting for assessing student weight control intentions and the extent to which they used the WAVE strategies to control their weight. The Youth WAVE Screener was administered to fifth-grade students in an inner-city school located in the Bronx, New York. The study was conducted in part to increase student awareness of snack foods and sugary beverages in relation to weight. Of the 169 students who completed the survey, 45.5% (n = 77) were trying to lose weight. Students who were trying to lose weight were more likely to have low-fat dairy products, less likely to have sugary beverages, and less likely to eat junk foods than those who were not trying to lose weight. Students who reported exercising 3 times weekly were more likely to report healthier dietary patterns and less sedentary behaviors than were students who exercise less often. Feedback and dialogue with fifth graders addressed the relationship between TV viewing and eating behavior, advertisement, availability, and preferences of fruits and vegetables. The Youth WAVE Screener can be used to quickly identify children who are concerned about their weight as well as those with dietary and physical activity patterns that may increase the risk of obesity. Diabetes educators can use this screener to start a dialogue with children about their weight-related behaviors.

    Physical inactivity is highly associated with mortality, especially in patients with coronary heart disease. We evaluated the effect of perceived health competence, a patient's belief in his or her ability to achieve health-related goals, on cumulative physical activity levels in the Mid-South Coronary Heart Disease Cohort Study. The Mid-South Coronary Heart Disease Cohort Study consists of 2,587 outpatients (32% were female) with coronary heart disease at an academic medical center network in the United States. Cumulative physical activity was quantified in metabolic equivalent (MET)-minutes per week with the International Physical Activity Questionnaire. We investigated associations between the 2-item Perceived Health Competence Scale (PHCS-2) and MET-minutes/week after adjusting for co-morbidities and psychosocial factors with linear regression. Nearly half of participants (47%) exhibited low physical activity levels (Perceived health competence was highly associated with physical activity after multivariable adjustment. A nonlinear relation was observed, with the strongest effect on physical activity occurring at lower levels of perceived health competence. There was effect modification by gender (p = 0.03 for interaction). The relation between perceived health competence and physical activity was stronger in women compared with men; an increase in the PHCS-2 from 3 to 4 was associated with a 73% increase in MET-minutes/week in women (95% confidence interval 43% to 109%, p perceived health competence was strongly associated with less physical activity in patients with coronary heart disease and may represent a potential target for behavioral interventions.

    Neighbourhood contextual factors such as accessibility of food shops and green spaces are associated with adult bodyweight but not necessarily weight-related behaviours. Whether these associations are replicated amongst children is unknown. To understand which aspects of childrens' neighbourhoods are associated with unhealthy weight and weight-related behaviours. Individual-level data for children from the 2006/7 New Zealand Health Survey (of Body Mass Index (BMI), dietary indicators and socioeconomic variables) were linked with geographic level data on neighbourhood deprivation, rural/urban status, percentage of community engaged in active travel, access to green space, food shops and sports/leisure facilities. Logistic regression models were fitted for measures of BMI and weight-related behaviours; sugar sweetened beverage (SSB) consumption; fast-food consumption; and television viewing. Increased community engagement in active transport was, counterintuitively, the only neighbourhood contextual factor associated with unhealthy weight amongst children. After adjustment for socioeconomic and environmental variables, greater access to green space appeared to have a protective effect on SSB consumption and neighbourhood deprivation was associated with all three unhealthy weight-related behaviours (SSB and fast-food consumption and television viewing). Although further research is needed, evidence from the current study suggests that a repertoire of health promotion interventions and policies to change unhealthy weight-related behaviours in high deprivation neighbourhoods may be required to address childhood obesity.

    Milrinone reduces the risk of low cardiac output syndrome for some pediatric patients after congenital heart surgery. Data from adults undergoing cardiac surgery suggest an association between milrinone and an increased risk of postoperative arrhythmias. We tested the hypothesis that milrinone is an independent risk factor for tachyarrhythmias after congenital heart surgery. Subjects undergoing congenital heart surgery at our institution were consecutively enrolled for 38 months, through September 2010. The data were prospectively collected, including a review of full-disclosure telemetry and the medical records. Within 38 months, 603 enrolled subjects underwent 724 operative procedures. The median age was 5.5 months (range 0.0 to 426), the median weight was 6.0 kg (range 0.7 to 108), and the cohort was 45% female. The overall arrhythmia incidence was 50%, most commonly monomorphic ventricular tachycardia (n = 85, 12%), junctional ectopic tachycardia (n = 69, 10%), accelerated junctional rhythm (n = 58, 8%), and atrial tachyarrhythmias (including atrial fibrillation, atrial flutter, and ectopic or chaotic atrial tachycardia, n = 58, 8%). Multivariate logistic regression analysis demonstrated that independent of age 3, and the use of epinephrine or dopamine, milrinone use on admission to the cardiac intensive care unit remained independently associated with an increase in the odds of postoperative tachyarrhythmia resulting in an intervention (odds ratio 2.8, 95% confidence interval 1.3 to 6.0, p = 0.007). In conclusion, milrinone use is an independent risk factor for clinically significant tachyarrhythmias in the early postoperative period after congenital heart surgery. Copyright © 2011 Elsevier Inc.

    The relative importance of loss of control and overeating in the relationship between binge eating and eating-related and general psychopathology has been debated in the literature. This study assessed the prevalence and correlates of overeating with and without loss of control within a diverse, population-based sample of adolescents. A highly diverse (81.1% non-White) sample of adolescents (n = 2,793) from EAT-2010 (Eating and Activity in Teens) completed self-report questionnaires assessing eating-related psychopathology, substance use, nonsuicidal self-injury, depressive symptoms, and self-esteem. Overeating without loss of control was reported by 6.9% of girls and 5.0% of boys, while 9.6% of girls and 6.3% of boys reported overeating with loss of control (binge eating). Overall, overeating (with or without loss of control) was positively associated with unhealthy or extreme weight control behaviors, dieting, nonsuicidal self-injury, lower body satisfaction, and self-esteem, and higher depressive symptoms relative to no overeating. Among girls, binge eating was associated with unhealthy or extreme weight control behaviors, lower self-esteem, and higher depressive symptoms relative to overeating without loss of control, while in boys, binge eating was associated with greater cigarette usage, lower body satisfaction, and greater depressive symptoms than overeating without loss of control (although cigarette usage was comparable in boys reporting binge eating and no overeating). Any overeating, with or without loss of control, was associated with multiple adverse correlates among adolescents. Loss of control was uniquely associated with multiple health indicators, further highlighting its importance as a marker of severity of overeating. © 2015 Wiley Periodicals, Inc.

    It is suggested, that a relative placental insufficiency in late pregnancy is one of the releasing factors of childbirth. Under this assumption 1027 deliveries in term pregnancy (266th-294th day of pregnancy) were inquired on the interrelationship between the ratio brith-weight: placental-weight and the duration of pregnancy. The average birth-weight increases slighly but significantly with the duration of pregnancy just as the average placental-weight. The average ratio birth-weight: placental-weight decreases significantly: The more unfavorable the ratio birth-weight: placental-weight is, the shorter remains the fetus in utero. This underlines the assumption of a relative placental insufficiency as one of the releasing factors of childbirth.

  5. Factors related to outcome in heart failure with a preserved (or normal) left ventricular ejection fraction.

    2016-07-01

    Heart failure with a preserved ejection faction (HFpEF) is a growing and expensive cause of heart failure (HF) affecting particularly the elderly. It differs in substantial ways in addition to the normal left ventricular ejection fraction, from the more easily recognized form of heart failure with a reduced ejection fraction (HFrEF or 'systolic heart failure') and unlike HFrEF there have been little advances in treatment. In part, this relates to the complexity of the pathophysiology and identifying the correct targets. In HFpEF, there appears to be widespread stiffening of the vasculature and the myocardium affecting ventricular function (both systolic and diastolic), impeding ventricular suction, and thus early diastolic filling leading to breathlessness on exertion and later atrial failure and fibrillation. Left ventricular ejection fraction tends to gradually decline and some evolve into HFrEF. Most patients also have a mixture of several co-morbidities including hypertension, diabetes, obesity, poor renal function, lack of fitness, and often poor social conditions. Therefore, many factors may influence outcome in an individual patient. In this review, the epidemiology, possible causation, pathophysiology, the influence of co-morbidities and some of the many potential predictors of outcome will be considered.

    Of the major risk factors of coronary heart disease dyslipoproteinemia, obesity, hypertension, and diabetes are nutrition related and can be considered of metabolic origin. Dyslipoproteinemia affects 2/3 of the adult population. The risk of coronary heart disease can be decreased 2-5 fold by lowering hypercholesterinemia; atherosclerosis in the coronaries may regress and total mortality may decrease. Atherogenic dyslipidemia (i.e. hypertriglyceridaemia, low HDL cholesterol levels, elevated concentrations of small dense LDL) increases the risk as part of the metabolic syndrome. Obesity is already highly prevalent, and it is affecting ever growing proportions of the adult population. Abdominal obesity furthermore predisposes patients to complications. No effective therapy is available for obesity. 3/4 of hypertensive patients are obese and more than half of them have insulin resistance. By decreasing blood pressure, the risk of stroke decreases by about 40%, that of coronary heart disease by 14-30%. Slimming cures are the most important non-pharmacological way of treating hypertension. 5% of the population has diabetes mellitus, and a further 5% has impaired glucose tolerance. Type 2 diabetes predisposes patients to macrovascular complications. The risk of coronary heart disease can be decreased by controlling diabetes by e.g. metformin.

    Insomnia is a condition that affects the nervous and muscular system. Thirty percent of the population between 18 and 60 years suffers from insomnia. The effects of this disorder involve problems such as poor school or job performance and traffic accidents. In addition, patients with insomnia present changes in the cardiac function during sleep. Furthermore, the structure of electroencephalographic A-phases, which builds up the Cyclic Alternating Pattern during sleep, is related to the insomnia events. Therefore, the relationship between these brain activations (A-phases) and the autonomic nervous system would be of interest, revealing the interplay of central and autonomic activity during insomnia. With this goal, a study of the relationship between A-phases and heart rate fluctuations is presented. Polysomnography recording of five healthy subjects, five sleep misperception patients and five patients with psychophysiological insomnia were used in the study. Detrended Fluctuation Analysis (DFA) was used in order to evaluate the heart rate dynamics and this was correlated with the number of A-phases. The results suggest that pathological patients present changes in the dynamics of the heart rate. This is reflected in the modification of A-phases dynamics, which seems to modify of heart rate dynamics.

    Birth weight is a crucial determinant of the development potential of the newborn. Abnormal newborn weights are associated with negative effects on the health and survival of the baby and the mother. Therefore, this study was designed to determine the prevalence of abnormal birth weight and related factors in Northern region, Ghana. The study was a facility-based cross-sectional survey in five hospitals in Northern region, Ghana. These hospitals were selected based on the different socio-economic backgrounds of their clients. The data on birth weight and other factors were derived from hospital records. It was observed that low birth weight is still highly prevalent (29.6%), while macrosomia (10.5%) is also increasingly becoming important. There were marginal differences in low birth weight observed across public hospitals but marked difference in low birth weight was observed in Cienfuegos Suglo Specialist Hospital (Private hospital) as compared to the public hospitals. The private hospital also had the highest prevalence of macrosomia (20.1%). Parity (0-1) (p malnutrition phenomenon, which is currently being experienced by developing and transition counties. Both low birth weight and macrosomia are risk factors, which could contribute considerably to the current and future burden of diseases. This may overstretch the already fragile health system in Ghana. Therefore, it is prudent to recommend that policies aiming at reducing diet related diseases should focus on addressing malnutrition during pregnancy and early life.

    'Low-carb' diets have been suggested to be effective in body weight (BW) management. However, these diets are relatively high in protein as well. To unravel whether body-weight loss and weight-maintenance depends on the high-protein or the 'low-carb' component of the diet. Body-weight (BW), fat mass (FM), blood- and urine-parameters of 132 participants (age=50 ± 12 yr; BW=107 ± 20 kg; BMI=37 ± 6 kg/m(2); FM=47.5 ± 11.9 kg) were compared after 3 and 12 months between four energy-restricted diets with 33% of energy requirement for the first 3 months, and 67% for the last 9 months: normal-protein normal-carbohydrate (NPNC), normal-protein low-carbohydrate (NPLC); high-protein normal-carbohydrate (HPNC), high-protein low-carbohydrate (HPLC); 24h N-analyses confirmed daily protein intakes for the normal-protein diets of 0.7 ± 0.1 and for the high-protein diets of 1.1 ± 0.2g/kg BW (pvs. NP (-11.5 ± 4 kg; -9.3 ± 0.7 kg) (pvs. NC (-12.3 ± 3 kg; -10.3 ± 1.1 kg) (ns).

    Full Text Available Abstract Background Responsiveness, or sensitivity to clinical change, is an important consideration in selection of a health-related quality of life (HRQL measure for trials or clinical applications. Many approaches can be used to assess responsiveness, which may affect the interpretation of study results. We compared the relative responsiveness of generic and heart failure specific HRQL instruments, as measured both by common psychometric indices and by external clinical criteria. Methods We analyzed data collected at baseline and 6-weeks in 298 subjects with heart failure on the following HRQL measures: EQ-5D (US, UK, and VAS Scoring, Kansas City Cardiomyopathy Questionnaire (KCCQ (Clinical and Overall Summary Score, and RAND12 (Physical and Mental Component Summaries. Three external indicators of clinical change were used to classify subjects as improved, deteriorated, or unchanged: 6-minute walk test, New York Heart Association (NYHA class, and physician global rating of change. Four responsiveness statistics (T-test, effect size, Guyatt's responsiveness statistic, and standardized response mean were used to evaluate the responsiveness of the select measures. The median rank of each HRQL measure across responsiveness indices and clinical criteria was then determined. Results Average age of subjects was 60 years, 75 percent were male, and had moderate to severe heart failure symptoms. Overall, the KCCQ Summary Scores had the highest relative ranking, irrespective of the responsiveness index or external criterion used. Importantly, we observed that the relative ranking of responsiveness of the generic measures (i.e. EQ-5D, RAND12 was influenced by both the responsive indices and external criterion used. Conclusion The disease specific KCCQ was the most responsive HRQL measure assessing change over a 6-week period, although generic measures provide information for which the KCCQ is not suitable. The responsiveness of generic HRQL measures may

    Many smokers believe that smoking helps them to control their weight, and concerns about weight gain can interfere with smoking cessation. As researchers typically assess general weight concerns, a measure specific to smoking-related weight concerns is needed. The Smoking-related Weight and Eating Episodes Test (SWEET) was created by generating items from 4 content domains: Hunger, Craving, Overeating, and Body Image. Female undergraduate smokers (N = 280) rated their postcessation weight gain concern and completed the SWEET, Fagerström Test for Nicotine Dependence, Brief Smoking Consequences Questionnaire-Adult, Eating Attitudes Test (EAT)-26, Bulimia Test-Revised (BULIT-R), and Body Shape Questionnaire. Factor analysis of the initial items suggested a 4-factor solution, suggesting 4 subscales: Smoking to suppress appetite, smoking to prevent overeating, smoking to cope with body dissatisfaction, and withdrawal-related appetite increases. Based on these results, the SWEET subscales were revised and shortened. The resulting 10-item SWEET showed excellent internal consistency (total α = .94; mean α = .86) and evidence of validity by predicting smoking frequency, eating pathology, and body image concerns (ps < .05). Smoking frequency, eating pathology, and body image concerns were significantly predicted by the SWEET while controlling for existing measures of postcessation weight gain concern. The SWEET appears to be a reliable and valid measure of tendencies to smoke in response to body image concern and nicotine withdrawal and as a way to control appetite and overeating.

This concept analysis provided a new meaning of risk in relation to CHD among FAs and shed light on further understanding of risk. Risk has been laced with negativity in health care, but based on the current literature, risk can be conceptualized in a positive perspective, especially in the area of chronic health disease such as CHD. However, further research is needed in the conceptualization of risk related to CHD for consistency, adequacy, and meaning. © 2010 Wiley Periodicals, Inc.

    The objective of this study was to examine the effect of swimming exercise on aging-related Ca2+ handling alterations and structural abnormalities of female rat heart. For this purpose, 4-month and 24-month old female rats were used and divided into three following groups: sedentary young (SY), sedentary old (SO), and exercised old (Ex-O). Swimming exercise was performed for 8 weeks (60 min/day, 5 days/week). Myocyte shortening, L-type Ca2+ currents and associated Ca2+ transients were measured from ventricular myocytes at 36 ± 1°C. NOX-4 levels, aconitase activity, glutathione measurements and ultrastructural examination by electron microscopy were conducted in heart tissue. Swimming exercise reversed the reduced shortening and slowed kinetics of aged cardiomyocytes. Although the current density was similar for all groups, Ca2+ transients were higher in SO and Ex-O myocytes with respect to the SY group. Caffeine-induced Ca2+ transients and the integrated NCX current were lower in cardiomyocytes of SY rats compared with other groups, suggesting an increased sarcoplasmic reticulum Ca2+ content in an aged heart. Aging led to upregulated cardiac NOX-4 along with declined aconitase activity. Although it did not reverse these oxidative parameters, swimming exercise achieved a significant increase in glutathione levels and improved structural alterations of old rats' hearts. We conclude that swimming exercise upregulates antioxidant defense capacity and improves structural abnormalities of senescent female rat heart, although it does not change Ca2+ handling alterations further. Thereby, it improves contractile function of aged myocardium by mitigating detrimental effects of oxidative stress.

    Obesity and associated metabolic disorders are related to impairments of the intestinal barrier. We examined lactulose:mannitol (Lac:Man) permeability in obese individuals with and without liver steatosis undergoing a weight-reduction program to test whether an effective weight-loss program improves gut barrier function and whether obese patients with or without liver steatosis differ in this function. Twenty-seven adult, nondiabetic individuals [mean ± SD body mass index (BMI; in kg/m 2 ): 43.7 ± 5.2; 78% with moderate or severe liver steatosis] were included in the follow-up intervention study (n = 13 by month 12). All patients reduced their weight to a mean ± SD BMI of 36.4 ± 5.1 within 12 mo. We assessed barrier functions by the oral Lac:Man and the fecal zonulin tests. Insulin resistance was assessed by the homeostatic model assessment index (HOMA), and liver steatosis by sonography and the fatty liver index (FLI). The Lac:Man ratio and circulating interleukin (IL) 6 concentration decreased during intervention from 0.080 (95% CI: 0.073, 0.093) to 0.027 (95% CI: 0.024, 0.034; P < 0.001) and from 4.2 ± 1.4 to 2.8 ± 1.6 pg/mL (P < 0.01), respectively. At study start, the Lac:Man ratio was higher in patients with moderate or severe steatosis than in those without any steatosis (P < 0.001). The Lac:Man ratio tended to correlate with HOMA (ρ = 0.55, P = 0.052), which correlated with FLI (ρ = 0.75, P < 0.01). A multiple-regression analysis led to a final model explaining FLI best through BMI, waist circumference, and the Lac:Man ratio. Intestinal permeability is increased in obese patients with steatosis compared with obese patients without. The increased permeability fell to within the previously reported normal range after weight reduction. The data suggest that a leaky gut barrier is linked with liver steatosis and could be a new target for future steatosis therapies.

    Objective: To examine the status and related factors for gestational weight gain of Chinese pregnant women at different trimesters in 2010-2012. Methods: Participants were from Chinese National Nutrition and Health Surveillance in 2010-2012. Using a multi-stage stratified cluster random sampling method, we recruited 2 805 singleton pregnant women with gestational age 13 weeks or more from 31 provinces of China. A standard questionnaire was used to collect general information and pre-pregnancy weight; body weight and height of pregnant women were measured using a unified weighing scale and stadiometer, dietary intake during the previous year was collected using a food frequency questionnaire. A multiple logistic regression was used to analyze potential factors associated with appropriate gestational weight gain. Results: Among 2 805 pregnant women, 1 441 were in the second (13-27 weeks) and 1 364 in the third trimesters (≥28 weeks) . In the 2(nd) trimester, 229 cases (15.9%), 440 cases (30.5%) and 772 cases (53.6%) were insufficient gestational weight gain, appropriate gestational weight gain and excessive gestational weight gain respectively. So were 256 cases (18.8%), 474 cases (34.8%), 634 cases (46.5%) in the 3(rd) trimester respectively. In the multivariate unconditional logistic model, less fruit intake was associated with insufficient weight gain for women in the 2(nd) trimester ( OR (95% CI ): 1.58 (1.06-2.34)). Pregnant women with Han ethnicity who live in the small/medium city had lower risk of insufficient weight gain in the 3(rd) trimester ( OR (95% CI ): 0.58 (0.34-0.98)). Those pregnant women with physical activity gain ( OR (95% CI ): 1.33 (1.02-1.73)). Conclusion: The prevalence of appropriate gestational weight gain was low in China. Our study suggests that pregnant weight gain is associated with fruit intake, types of residential area and physical activity.

    The data of the 2,040 single births, born during 1987 at the "Saint Antoine" Hospital in Paris, were analysed in order to identify the impact of various biological, occupational, and socioeconomic factors on gestational age and birth weight. Birth weight is associated with the height of the mother and the weight gained during pregnancy. It is lower for mothers with preeclampsia during the current or previous pregnancies or with urogenital infections during the current pregnancy and for mothers with one or more induced abortions. Girls weigh less than boys. Parity has a positive relation to the baby's weight, while manual work seems to have a negative one. APGAR score and duration of the pregnancy are associated with the birth weight. Placenta previa, preeclampsia and urinary infections affect the gestational age. A short pause period in work is related to a shorter gestational age. Weight gain is associated with a prolonged duration of the pregnancy. Gestational age and birth weight are associated with the nationality of the mother, especially in some ethnic groups, and with marital status.

    Examine relationships between weight-related factors and weight status, body dissatisfaction, chronic health conditions, and quality of life across sexual orientation and gender. Two- and four-year college students participated in the College Student Health Survey (n = 28,703; 2009-2013). Risk differences were calculated to estimate relationships between behavioral profiles and weight status, body satisfaction, diagnosis of a chronic condition, and quality of life, stratified by gender and sexual orientation. Four behavioral profiles, characterized as "healthier eating habits, more physically active," "healthier eating habits," "moderate eating habits," and "unhealthy weight control," were utilized based on latent class analyses, estimated from nine weight-related behavioral survey items. Sexual orientation differences in weight and quality of life were identified. For example, sexual minority groups reported significantly poorer quality of life than their heterosexual counterparts (females: 22.5%-38.6% (sexual minority) vs. 19.8% (heterosexual); males: 14.3%-26.7% (sexual minority) vs. 11.8% (heterosexual)). Compared with the "healthier eating habits, more physically active" profile, the "unhealthy weight control" profile was associated with obesity, poor body satisfaction, and poor quality of life in multiple gender/sexual orientation subgroups. Interventions are needed to address obesity, body dissatisfaction, and poor quality of life among sexual minority college students. © 2016 The Obesity Society.

    The objective of this study was to estimate economic weights of Hanwoo carcass traits that can be used to build economic selection indexes for selection of seedstocks. Data from carcass measures for determining beef yield and quality grades were collected and provided by the Korean Institute for Animal Products Quality Evaluation (KAPE). Out of 1,556,971 records, 476,430 records collected from 13 abattoirs from 2008 to 2010 after deletion of outlying observations were used to estimate relative economic weights of bid price per kg carcass weight on cold carcass weight (CW), eye muscle area (EMA), backfat thickness (BF) and marbling score (MS) and the phenotypic relationships among component traits. Price of carcass tended to increase linearly as yield grades or quality grades, in marginal or in combination, increased. Partial regression coefficients for MS, EMA, BF, and for CW in original scales were +948.5 won/score, +27.3 won/cm2, −95.2 won/mm and +7.3 won/kg when all three sex categories were taken into account. Among four grade determining traits, relative economic weight of MS was the greatest. Variations in partial regression coefficients by sex categories were great but the trends in relative weights for each carcass measures were similar. Relative economic weights of four traits in integer values when standardized measures were fit into covariance model were +4:+1:−1:+1 for MS:EMA:BF:CW. Further research is required to account for the cost of production per unit carcass weight or per unit production under different economic situations. PMID:25049531

    Weight misperception occurs when there is a discrepancy between one's actual and perceived weight status. Among adolescents with overweight/obesity, many believe that correcting weight misperception is imperative to inspire weight-related behavior change. However, past research has shown that adolescents with overweight/obesity who misperceive their weight status gain less weight over time compared to accurate perceivers. Therefore, our objective was to examine possible mechanisms underlying this relationship. Specifically, we examined the association between weight misperception and engagement in weight-related health behaviors among adolescents with overweight/obesity. Self-reported data from the 2015 National Youth Risk Behavior Survey was used in analyses restricted to participants with overweight/obesity (n = 4383). Using multivariate logistic models correcting for sex, race/ethnicity, and grade in school, we examined the cross-sectional associations between weight misperception and engagement in weight-related health behaviors, specifically related to dietary intake, physical activity, and sleep. Adolescents with overweight/obesity who misperceived their weight status were more likely to drink 100% fruit juice two or more times per day (OR = 1.53, 95% CI: 1.20, 1.94), eat vegetables two or more times per day (OR = 1.29, 95% CI: 1.07, 1.57), be physically active for 1 hour or more per day for at least 5 days in the week prior (OR = 1.40, 95% CI: 1.15, 1.72), be on a sports team in the last year (OR = 1.55, 95% CI: 1.21, 1.97), sleep an average of at least 8 hours per school night (OR = 1.40, 95% CI: 1.15, 1.72), and less likely to be trying to lose weight (OR = 0.17, 95% CI: 0.15, 0.20). Misperceivers were more likely to consume breakfast every morning in the week prior and to drink a sports drink at least once per day, though these results were not statistically significant. We observed no difference in fruit intake, soda intake

    Proton pump inhibitors (PPIs) are among the commonest drugs used nowadays. The aim of our study was to analyze prolonged utilization of proton pump inhibitors in medical therapy of patients with ischemic and valvular heart disease. Secondly, profile of utilization was scrutinized to patient characteristics and type of cardiovascular treatments. The study included consecutive patients scheduled for cardiovascular rehabilitation 2-6months after index cardiovascular treatment. Two hundred ninety-four patients (n=294/604; 48.7%) have been using proton pump inhibitor in their therapy after index cardiovascular treatment. Cardiovascular treatments were powerfully connected with utilization of PPIs; surgery 5.77 (95%-confidence intervals [CI]: 4.05-8.22; pvalvular heart disease utilized proton pump inhibitor in prolonged courses. Prolonged courses of PPIs were connected with existence and worsening of red blood count indexes, older age, lesser weight of patients and underutilization of cardioprotective drugs.

Anti-fat beliefs are rapidly globalizing. The goal of the study is to (1) examine how weight-related stigma, enacted as teasing, is evident among women from a lower-income country and (2) test if such weight-related stigma contributes to depressive symptoms. Modeling data for 12,074 reproductive-age women collected in the 2008-2009 Guatemala National Maternal-Infant Health Survey, we demonstrate that weight-related teasing is (1) experienced by those both underweight and overweight, and (2) a significant psychosocial stressor. Effects are comparable to other factors known to influence women's depressive risk in lower-income countries, such as living in poverty, experiencing food insecurity, or suffering sexual/domestic violence. That women's failure to meet local body norms-whether they are overweight or underweight-serves as such a strong source of psychological distress is particularly concerning in settings like Guatemala where high levels of over- and under-nutrition intersect at the household and community level. Current obesity-centric models of weight-related stigma, developed from studies in high-income countries, fail to recognize that being underweight may create similar forms of psychosocial distress in low-income countries.

    Given the continuing epidemic of obesity, policymakers are increasingly looking for levers within the local retail food environment as a means of promoting healthy weights. To examine the independent and joint associations of absolute and relative densities of restaurants near home with weight status in a large, urban, population-based sample of adults. We studied 10,199 adults living in one of four cities in southern Ontario, Canada, who participated in the Canadian Community Health Survey (cycles 2005, 2007/08, 2009/10). Multivariate models assessed the association of weight status (obesity and body mass index) with absolute densities (numbers) of fast-food, full-service and other restaurants, and the relative density (proportion) of fast-food restaurants (FFR) relative to all restaurants within ~10-minute walk of residential areas. Higher numbers of restaurants of any type were inversely related to excess weight, even in models adjusting for a range of individual covariates and area deprivation. However, these associations were no longer significant after accounting for higher walkability of areas with high volumes of restaurants. In contrast, there was a direct relationship between the proportion of FFR relative to all restaurants and excess weight, particularly in areas with high volumes of FFR (e.g., odds ratio for obesity=2.55 in areas with 5+ FFR, 95% confidence interval: 1.55-4.17, across the interquartile range). Policies aiming to promote healthy weights that target the volume of certain retail food outlets in residential settings may be more effective if they also consider the relative share of outlets serving more and less healthful foods.

    Adiponectin is an adipose-derived protein with beneficial metabolic effects. Low adiponectin is associated with obesity and related diseases. Significant weight loss increases adiponectin, reducing disease risk. This study compared the effects of two weight-loss diets with different macronutrient compositions on adiponectin. Eighty-one obese women in two cohorts were randomized to a low-fat (LF) or a low-carbohydrate (LC) diet. All subjects underwent equivalent weight-loss intervention, with weight and other measures assessed at baseline and after 6 (cohort I) or 4 (cohort II) months. Body fat was measured by dual energy X-ray absorptiometry. Adiponectin was measured by radioimmunoassay. Diet intake was assessed using 24-h recalls and 3-day diet records. Data were analyzed via t-tests and repeated-measures factorial ANOVA using time, diet, and replicate (cohort I vs. cohort II) as factors. Age, weight, body fat, BMI, adiponectin, and diet were similar at baseline. Following intervention, macronutrient composition of the diet was vastly different between the groups, reflecting the assigned diet. Both groups lost weight and body fat (P vs. -4.97 kg weight, P vs. -2.62 kg fat, P < 0.001). Adiponectin increased in the LC (+1.92 mcg/ml, P < 0.01), but not the LF (+0.86 mcg/ml, P = 0.81), group. There was no correlation between weight loss and increase in adiponectin. These results confirm that diet-induced loss of weight and body fat is associated with increased adiponectin concentrations. This effect is evident with weight loss of 10% or more, and may be greater with LC diets.

    Purpose: Due to the shortage of cadaver donors, living related liver donation (LRLD) has emerged as an alternative to cadaver donation. The expected graft weight is one of the main determinants for donor selection. This study investigates the accuracy of preoperatively performed CT-volumetry to predict the actual weight of the right liver lobe graft. Materials and methods: In a prospective study the weight of the right hepatic lobe was calculated by volumetric analysis based on CT in 33 patients (21 females, 12 males, mean age 42.1 years, median age 41 years) prior to living related liver donation. Graft weight was calculated as the product of CT-based graft volume and 1.00 g/ml (the approximated density of healthy liver parenchyma). The calculated weight was compared with the intraoperatively measured weight of the harvested right hepatic lobe. The difference was used to determine a correction factor for estimating the actual graft weight. Results: Based on the assumption of a parenchymal density of 1.00 g/ml, the preoperatively estimated graft weight (mean 980 g ± 168 g) deviated + 33% from the intraoperatively measured right hepatic lobe weight (mean 749 g ± 170 g). By reducing the preoperatively predicted weight of the right hepatic lobe with a correction factor of 0.75, the actual graft weight can be calculated [de

    It has recently become possible to obtain T{sub 2}-weighted images using turbo spin echo with a preparation pulse to inhibit the signal from flowing blood (dark blood turbo spin echo: DB-TSE) during breath holding. In order to obtain higher-quality T{sub 2}-weighted images of the heart, we assessed the optimum preset repetition time (TR preset), the interval between the dark blood preparation pulse and the end of data acquisition on DB-TSE. DB-TSE left ventricular short-axis images were obtained with varying TR presets in eight volunteers. Signal intensity was measured for the myocardium and blood in the left ventricular cavity, and the signal intensity ratio of myocardium to blood was calculated. The optimum TR preset was determined so as to give the highest signal intensity ratio of myocardium to blood. A comparison was made of the myocardium-to-blood ratios between the eight volunteers and nine patients. The optimum TR preset changed according to the cardiac cycle. By using the optimum TR preset, we obtained the peak signal intensity ratios in the volunteers and the patients. By using DB-TSE with the optimum TR preset for the cardiac cycle, we can obtain better quality T{sub 2}-weighted images of the heart. (author)

    Abstract Objective To investigate a new approach to calculating cause-related standardized mortality rates that involves assigning weights to each cause of death reported on death certificates. Methods We derived cause-related standardized mortality rates from death certificate data for France in 2010 using: (i) the classic method, which considered only the underlying cause of death; and (ii) three novel multiple-cause-of-death weighting methods, which assigned weights to multiple causes of death mentioned on death certificates: the first two multiple-cause-of-death methods assigned non-zero weights to all causes mentioned and the third assigned non-zero weights to only the underlying cause and other contributing causes that were not part of the main morbid process. As the sum of the weights for each death certificate was 1, each death had an equal influence on mortality estimates and the total number of deaths was unchanged. Mortality rates derived using the different methods were compared. Findings On average, 3.4 causes per death were listed on each certificate. The standardized mortality rate calculated using the third multiple-cause-of-death weighting method was more than 20% higher than that calculated using the classic method for five disease categories: skin diseases, mental disorders, endocrine and nutritional diseases, blood diseases and genitourinary diseases. Moreover, this method highlighted the mortality burden associated with certain diseases in specific age groups. Conclusion A multiple-cause-of-death weighting approach to calculating cause-related standardized mortality rates from death certificate data identified conditions that contributed more to mortality than indicated by the classic method. This new approach holds promise for identifying underrecognized contributors to mortality. PMID:27994280

    Full Text Available The objective of the papper was to verify the relationship between dietary intake and interdialytic weight gain in patients with chronic kidney disease. Cross-sectional study, in a renal clinic in Irati, Paraná, Brazil. Prehemodialysis weight and weight after hemodialysis were evaluated. Food intake was analyzed according to food frequency and usual food day (DAH. The data were evaluated descriptively and also through the chi-square test, Student's t-test and Mann-Whitney test. Sixty-one patients (54.1% participated in the study, with a mean age of 57.78±14.58 years, 62.3% of males. The mean pre-hemodialysis weight was 68.28±15.14 kg, while hemodialysis was 65.63±15.01 kg (p0.05. The other food groups (meat, cereals, fats and sweets also had no association with weight gain (p> 0.05. When the nutrients were compared, according to the DAH, there was no relation with the interdialytic weight gain (p>0.05. Thus, it was observed that there was a relationship between interdialytic weight gain and macronutrient consumption; The same was not observed for micronutrients.

    To determine whether age-related differences in body weight loss in hyperthyroidism could be related to caloric intake, the body weight and food consumption of Fischer 344 male rats were monitored every other day for four weeks. Six-month-old (young) rats were compared to 16-month-old rats (intermediate age) and 25-month-old (aged) rats. Hypothyroidism was induced with 0.025% methimazole in the drinking water for four weeks. Hyperthyroidism was induced with triiodothyronine (T3) injections (15 micrograms/100 g body weight i.p.) for the last 10 days of observation. A group of young rats pair fed with aged rats was included as a control group. The body weight changes of aged rats were similar to hypothyroid young rats. An index of T3 catabolic effect was calculated based on the net weight loss and food intake. This index was not different in aged rats compared to young rats. The apparent hypersensitivity of aged rats to T3 as evidenced by excessive weight loss could totally be attributed to decreased caloric intake. It is concluded that aged rats compared to the young are not more sensitive to the overall catabolic effects of thyroid hormones.

    We examine weight control behavior used to (a) compensate for caloric content of heavy alcohol use; and (b) enhance the psychoactive effects of alcohol among college students. We evaluate the role of gender orientation and sex. Participants completed an online survey (N = 651; 59.9% women; 40.1% men). Weight control behavior was assessed via the Compensatory-Eating-and-Behaviors-in Response-to-Alcohol-Consumption-Scale. Control variables included sex, race/ethnicity, age, and depressive symptoms. Gender orientation was measured by the Bem Sex Role Inventory. The prevalence and probability of alcohol-related weight control behavior using ordinal logistic regression are reported. Men and women do not significantly differ in compensatory-weight-control-behavior. However, regression models suggest that recent binge drinking, other substance use, and masculine orientation are positively associated with alcohol-related weight control behavior. Sex was not a robust predictor of weight control behavior. Masculine orientation should be considered a possible risk factor for these behaviors and considered when designing prevention and intervention strategies.

  1. Bariatric surgery patients’ perceptions of weight-related stigma in healthcare settings impair post-surgery dietary adherence

    Full Text Available Background: Weight-related stigma is reported frequently by higher body-weight patients in healthcare settings. Bariatric surgery triggers profound weight loss. This weight loss may therefore alleviate patients’ experiences of weight-related stigma within healthcare settings. In non-clinical settings, weight-related stigma is associated with weight-inducing eating patterns. Dietary adherence is a major challenge after bariatric surgery.Objectives: (1 Evaluate the relationship between weight-related stigma and post-surgical dietary adherence; (2 understand if weight loss reduces weight-related stigma, thereby improving post-surgical dietary adherence; and (3 explore provider and patient perspectives on adherence and stigma in healthcare settings. Design: This mixed methods study contrasts survey responses from 300 postoperative bariatric patients with ethnographic data based on interviews with 35 patients and extensive multi-year participant-observation within a clinic setting. The survey measured experiences of weight-related stigma, including from healthcare professionals, on the Interpersonal Sources of Weight Stigma scale and internalized stigma based on the Weight Bias Internalization Scale. Dietary adherence measures included patient self-reports, non-disordered eating patterns reported on the Disordered Eating after Bariatric Surgery scale, and food frequencies. Regression was used to assess the relationships among post-surgical stigma, dietary adherence, and weight loss. Qualitative analyses consisted of thematic analysis.Results: The quantitative data show that internalized stigma and general experiences of weight-related stigma predict worse dietary adherence, even after weight is lost. The qualitative data show patients did not generally recognize this connection, and health professionals explained it as poor patient compliance.Conclusion: Reducing perceptions of weight-related stigma in healthcare settings and weight bias

    Simultaneous contributions of self-esteem, depression, and anxiety to weight and perceived physical health in young adults is understudied. A diverse sample of 424 young adults completed measures of shape/weight based self-esteem, depression, anxiety, and perceived physical health. Height and weight were measured to calculate body mass index (BMI). Latent profile analysis was conducted to derive patterns of depression, anxiety, and shape/weight based self-esteem. Then, we examined the association of the profiles with weight status and perceived physical health. Three profiles emerged: (1) High Shape/Weight Influence (HSWI); (2) Low Shape/Weight, Depression, & Anxiety Influence (LSWDAI); and (3) High Depression & Anxiety Influence (HDAI). The HSWI profile had significantly higher BMI than the LSWDAI and HDAI profiles, and significantly lower perceived physical health than the LSWDAI profile. Over emphasis on shape/weight, regardless of depression and anxiety, is associated with elevated weight and negative internalized health views. Copyright © 2018 Elsevier Ltd. All rights reserved.

  4. Bridging Weighted Rules and Graph Random Walks for Statistical Relational Models

    2018-02-01

    Full Text Available The aim of statistical relational learning is to learn statistical models from relational or graph-structured data. Three main statistical relational learning paradigms include weighted rule learning, random walks on graphs, and tensor factorization. These paradigms have been mostly developed and studied in isolation for many years, with few works attempting at understanding the relationship among them or combining them. In this article, we study the relationship between the path ranking algorithm (PRA, one of the most well-known relational learning methods in the graph random walk paradigm, and relational logistic regression (RLR, one of the recent developments in weighted rule learning. We provide a simple way to normalize relations and prove that relational logistic regression using normalized relations generalizes the path ranking algorithm. This result provides a better understanding of relational learning, especially for the weighted rule learning and graph random walk paradigms. It opens up the possibility of using the more flexible RLR rules within PRA models and even generalizing both by including normalized and unnormalized relations in the same model.

    The aim of the study was to compare the weight gain during pregnancy (using Institute of Medicine guidelines) among Asian Indians across different body mass index (BMI) categories (using World Health Organization Asia Pacific BMI cut points) and to compare the pregnancy outcomes in each of the different BMI categories. Retrospective records of 2728 pregnant women attending antenatal clinics and private maternity centers in Chennai, South India, from January 2011 to January 2014 were studied. Pregnancy outcomes were analyzed in relation to BMI and weight gain across different BMI categories. Overweight and obese women who gained more weight during pregnancy were at high risk of delivering macrosomic infants (overweight - odds ratio [OR]: 2.3, 95% confidence interval [CI]: 1.1-5.2, P = 0.02 and obese - OR: 1.6, 95% CI: 1.1-2.4, P = 0.01). In addition, obese women who gained more weight were also at high risk of preterm labor (OR: 2.1, 95% CI: 1.1-3.8; P = 0.01), cesarean section (OR: 1.9, 95% CI: 1.4-2.5; P women who gained less weight had a protective effect from cesarean section and macrosomia. Overweight/obese women who gained more weight than recommended are at a high risk of developing adverse pregnancy outcomes. Normal and overweight women who gained weight less than recommended have low risk for cesarean section and macrosomia. However, they have a higher (statistically insignificant) risk for low birth weight and preterm birth. This highlights the need for gaining adequate weight during pregnancy.

It was a prospective study that performed a secondary analysis of data from Project “Saúde na Boa”, which included youths attending night classes in secondary public schools in Recife in the state of Pernambuco and Florianópolis in the state of Santa Catarina. Data on the youths’ body type (thinness or excess weight and degree of satisfaction/dissatisfaction with body weight and lifestyle (level of physical activity, participation in physical education classes, sedentary behavior and snacks, soda and alcohol intake were collected at 10 schools from each town (five in the intervention group and five in the control group. The percentages of youths dissatisfied with their body weight were 50.5% and 48.6% at baseline and after intervention, respectively. The percentage of youths with body dissatisfaction due to thinness decreased (21.4% vs. 16.5%, while the percentage of youths with body dissatisfaction due to excess weight increased (29.1% vs. 32.1%. Approximately 41.2% of the youths with body dissatisfaction due to thinness and 18.3% of those dissatisfied due to excess weight became satisfied with their body weight after intervention. The intervention targeting health-related behaviors induced changes in the youths’ degree of satisfaction with their body weight.

    Purpose To examine parent and family variables in relation to adolescent weight control and eating behaviors, body satisfaction, and importance of thinness among overweight adolescents. Methods This study examined parent-reported use of weight control behaviors (i.e., healthy and unhealthy behaviors, behavioral changes, other diet strategies), parent psychosocial functioning (i.e., depression, self-esteem, body satisfaction, importance of thinness), and family functioning (i.e., cohesion and adaptability) in relation to adolescent weight control and eating behaviors, body satisfaction, and importance of thinness. Surveys were completed by 103 overweight (BMI ≥ 85th percentile) adolescents, ages 12 to 20, and their parents. Height and weight were also measured. Linear regression equations were used for continuous outcomes and logistic regression equations for dichotomous outcomes. Results Adolescent report of lower body satisfaction and engagement in more “severe” or less healthy forms of weight control behavior were associated with parent weight control behaviors. Adolescent report of overeating was associated with lower scores of family cohesion and adaptability. Adolescent report of lower body satisfaction was positively associated with parent report of body satisfaction and self-esteem. Adolescent report of greater importance placed on thinness was associated with parent report of lower self-esteem. Conclusions Findings indicate that several parent and family variables are associated with weight control behaviors, episodes of overeating, and body satisfaction and importance of thinness among overweight adolescents. Parent weight control behaviors and adolescent cognitions about body image may be important variables to target within intervention research and treatment programs for overweight youth.

    Full Text Available Abstract Background The measurement of health, the effects of disease, and the impact of health care include not only an indication of changes in disease frequency and severity but also an estimate of patients' perception of health status before and after treatment. One of the more important developments in health care in the past decade may be the recognition that the patient's perspective is as legitimate and valid as the clinician's in monitoring health care outcomes. This has lead to the development of instruments to quantify the patients' perception of their health status before and after treatment. Methods We review evidence supporting the measurement properties of the MacNew Heart Disease Health-related Quality of Life [MacNew] Questionnaire which was designed to evaluate how daily activities and physical, emotional, and social functioning are affected by coronary heart disease and its treatment. Results Reliability was demonstrated by using internal consistency and the intraclass correlation coefficients for the three domains in the Dutch, English, Farsi, German, and Spanish versions of the MacNew. With internal consistency and intraclass correlation coefficients =>0.73, reliability is high. Validity of the MacNew was examined with factor analysis and three core underlying factors, physical, emotional, and social, were identified, explaining 63.0 – 66.5% of the observed variance and replicated in the translations with psychometric data. Construct validity of the MacNew was further demonstrated by extensive substantiation of the logical relationships, defined a priori, between items and other comparison tools. The MacNew is responsive and sensitive to changes in HRQL following various interventions for patients with heart disease with 11 of 13 effect size statistics >0.80. Taking an average of 10 minutes or less to complete, the respondent-burden for the MacNew is low and its acceptability is demonstrated by response rates of over 90

    Electrical impedance tomography (EIT) can determine ventilation and perfusion relationship. Most of the data obtained so far originates from experimental settings and in healthy subjects. The aim of this study was to demonstrate that EIT measures the perioperative changes in pulmonary blood flow after repair of a ventricular septum defect in children with haemodynamic relevant septal defects undergoing open heart surgery. In a 19 bed intensive care unit in a tertiary children's hospital ventilation and cardiac related impedance changes were measured using EIT before and after surgery in 18 spontaneously breathing patients. The EIT signals were either filtered for ventilation (ΔZV) or for cardiac (ΔZQ) related impedance changes. Impedance signals were then normalized (normΔZV, normΔZQ) for calculation of the global and regional impedance related ventilation perfusion relationship (normΔZV/normΔZQ). We observed a trend towards increased normΔZV in all lung regions, a significantly decreased normΔZQ in the global and anterior, but not the posterior lung region. The normΔZV/normΔZQ was significantly increased in the global and anterior lung region. Our study qualitatively validates our previously published modified EIT filtration technique in the clinical setting of young children with significant left-to-right shunt undergoing corrective open heart surgery, where perioperative assessment of the ventilation perfusion relation is of high clinical relevance.

    [Purpose] The aim of the present study was to investigate the accuracy of a digital weight scale relative to the Wii in limb loading measurement during static standing. [Methods] This was a cross-sectional study conducted at a public university teaching hospital. The sample consisted of 24 participants (12 with osteoarthritis and 12 healthy) recruited through convenient sampling. Limb loading measurements were obtained using a digital weight scale and the Nintendo Wii in static standing with three trials under an eyes-open condition. The limb load asymmetry was computed as the symmetry index. [Results] The accuracy of measurement with the digital weight scale relative to the Nintendo Wii was analyzed using the receiver operating characteristic (ROC) curve and Kolmogorov-Smirnov test (K-S test). The area under the ROC curve was found to be 0.67. Logistic regression confirmed the validity of digital weight scale relative to the Nintendo Wii. The D statistics value from the K-S test was found to be 0.16, which confirmed that there was no significant difference in measurement between the equipment. [Conclusion] The digital weight scale is an accurate tool for measuring limb load asymmetry. The low price, easy availability, and maneuverability make it a good potential tool in clinical settings for measuring limb load asymmetry.

  12. Can mindfulness influence weight management related eating behaviors? If so, how?

    2017-04-01

    Mindfulness is increasingly being used for weight management. However, the strength of the evidence for such an approach is unclear; although mindfulness-based weight management programs have had some success, it is difficult to conclude that the mindfulness components were responsible. Research in this area is further complicated by the fact that the term 'mindfulness' is used to refer to a range of different practices. Additionally, we have little understanding of the mechanisms by which mindfulness might exert its effects. This review addresses these issues by examining research that has looked at the independent effects of mindfulness and mindfulness-related strategies on weight loss and weight management related eating behaviors. As well as looking at evidence for effects, the review also considers whether effects may vary with different types of strategy, and the kinds of mechanisms that may be responsible for any change. It is concluded that there is some evidence to support the effects of (a) present moment awareness, when applied to the sensory properties of food, and (b) decentering. However, research in these areas has yet to be examined in a controlled manner in relation to weight management. Crown Copyright © 2017. Published by Elsevier Ltd. All rights reserved.

    The aim of this study was to assess the relationship between self-reported weight change, socio-economic status, and health-related quality of life (HRQOL) in patients with diabetes, 5 years after they underwent coronary angiography. Between 2013 and 2014, 1873 of 4391 patients (319 with diabetes) who underwent coronary angiography between 2008 and 2009 participated in a follow-up study. Three out of four domains of the World Health Organization Quality of Life (WHOQOL)-BREF (physical health, psychological health and social relationships) were surveyed during the follow-up period. To assess the relationship between weight change and HRQOL, generalized linear models were constructed for every dimension of the WHOQOL-BREF, with educational level as a predictor and sex, age, marital status, smoking status, hypertension, cholesterol, ischemic heart disease, acute myocardial infarction, and stable angina pectoris as covariates. The mean age of the patients was 70 years and almost three-quarters of the patients (72.7 %) were men. During the 12 months preceding the follow-up survey, 22.6 % of the patients reported weight loss, 20 % reported weight gain, and 57.4 % reported no weight change. There were significant differences in the HRQOL scores between patients who reported weight loss and those who reported either weight gain or unchanged weight. The most affected domains were physical and psychological health, with higher scores for patients who reported weight loss (54.7 and 67.2, respectively) than those who reported weight gain (46.3 and 58.5, respectively). The generalized linear model confirmed higher HRQOL scores among patients who reported weight loss and revealed an association between the HRQOL score and education level. Weight change and education level were associated with HRQOL in patients with diabetes. Self-reported weight loss and no weight change were positively associated with HRQOL in patients with diabetes, while weight gain was negatively

    Background: Low birth weight is considered a risk factor for cardiovascular disease (CVD) in later life. Because data in children and adolescents are sparse and controversial, we assessed the association of birth weight with CVD risk factors in German youths. Methods: We categorized 843 urban children and adolescents aged 3-18 years by quintiles of birth weight and measured nine traditional risk factors in terms of body mass index (BMI), waist circumference (WC), systolic (SBP) and diastolic (DBP) blood pressure, total cholesterol (TC), LDL-C, HDL-C, Non HDL-C and triglycerides (TG). SPSS 21 was used for statistical analysis. Results: Mean values and prevalence of nine anthropometric and lipid risk variables were equally distributed over the five birth weight groups. Though risk factors clustered between 3.0 kg and 4.0 kg of birth weight in both genders we found only one significant correlation of birth weight with TG for males and females and another one for HDL-C in males. The strongest clustering of significant regression coefficients occurred in the 2nd birth weight quintile for SBP (ß 0.018), TC (ß -0.050), LDL-C (ß -0.039), non LDL-C (ß -0.049) and log TG (ß -0.001) in males and females. Conclusions: Overall we did not find significant associations between birth weight and nine traditional cardiovascular risk factors in children and adolescents. However, the 2nd quintile of birth weight might suggest clustering of risk factors. PMID:26900435

    Neonates born to overweight or obese women are larger and at higher risk of birth complications. Many maternal obesity-related traits are observationally associated with birth weight, but the causal nature of these associations is uncertain. To test for genetic evidence of causal associations of maternal body mass index (BMI) and related traits with birth weight. Mendelian randomization to test whether maternal BMI and obesity-related traits are potentially causally related to offspring birth weight. Data from 30,487 women in 18 studies were analyzed. Participants were of European ancestry from population- or community-based studies in Europe, North America, or Australia and were part of the Early Growth Genetics Consortium. Live, term, singleton offspring born between 1929 and 2013 were included. Genetic scores for BMI, fasting glucose level, type 2 diabetes, systolic blood pressure (SBP), triglyceride level, high-density lipoprotein cholesterol (HDL-C) level, vitamin D status, and adiponectin level. Offspring birth weight from 18 studies. Among the 30,487 newborns the mean birth weight in the various cohorts ranged from 3325 g to 3679 g. The maternal genetic score for BMI was associated with a 2-g (95% CI, 0 to 3 g) higher offspring birth weight per maternal BMI-raising allele (P = .008). The maternal genetic scores for fasting glucose and SBP were also associated with birth weight with effect sizes of 8 g (95% CI, 6 to 10 g) per glucose-raising allele (P = 7 × 10(-14)) and -4 g (95% CI, -6 to -2 g) per SBP-raising allele (P = 1×10(-5)), respectively. A 1-SD ( ≈ 4 points) genetically higher maternal BMI was associated with a 55-g higher offspring birth weight (95% CI, 17 to 93 g). A 1-SD ( ≈ 7.2 mg/dL) genetically higher maternal fasting glucose concentration was associated with 114-g higher offspring birth weight (95% CI, 80 to 147 g). However, a 1-SD ( ≈ 10 mm Hg) genetically higher maternal SBP was associated with a 208-g

    As further understanding is required of what behavioural factors are associated with long-term weight-loss success, the aim of the present study was to determine the prevalence of successful weight loss 15 months post-enrolment in a commercial web-based weight-loss programme and which behavioural factors were associated with success. An online survey was completed 15 months post-enrolment in a commercial web-based weight-loss programme to assess weight-related behaviours and current weight. Participants were classified as successful if they had lost ≥5 % of their starting weight after 15 months. Commercial users of a web-based weight-loss programme. Participants enrolled in the commercial programme between August 2007 and May 2008. Six hundred and seventy-seven participants completed the survey. The median (interquartile range) weight change was -2·7 (-8·2, 1·6) % of enrolment weight, with 37 % achieving ≥5 % weight loss. Multivariate logistic regression analysis found success was associated with frequency of weight self-monitoring, higher dietary restraint score, lower emotional eating score, not skipping meals, not keeping snack foods in the house and eating takeaway foods less frequently. The findings suggest that individuals trying to achieve or maintain ≥5 % weight loss should be advised to regularly weigh themselves, avoid skipping meals or keeping snack foods in the house, limit the frequency of takeaway food consumption, manage emotional eating and strengthen dietary restraint. Strategies to assist individuals make these changes to behaviour should be incorporated within obesity treatments to improve the likelihood of successful weight loss in the long term.

    Radiation weighting factors have long been employed to modify absorbed dose as part of the process of evaluating radiological impact to humans. Their use represents an acknowledgement of the fundamental difference in energy deposition patterns of charged and uncharged particles, and how this can translate into varying degrees of biological impact. Weighting factors used in human radiation protection are derived from a variety of endpoints taken from in-vitro experiments that include human and animal cell lines, as well as in-vivo experiments with animals. Nonetheless, the application of radiation weighting factors in the context of dose assessment of animals and plants is not without some controversy. Specifically, radiation protection of biota has largely focused on limiting deterministic effects, such as reduced reproductive fitness. Consequently, the application of conventional stochastic-based radiation weighting factors (when used for human protection) appears inappropriate. While based on research, radiation weighting factors represent the parsing of extensive laboratory studies on relative biological effectiveness. These studies demonstrate that the magnitude of a biological effect depends not just on dose, but also on other factors including the rate at which the dose is delivered, the type and energy of the radiation delivering the dose, and, most importantly, the endpoint under consideration. This article discusses the efforts taken to develop a logical, transparent, and defensible approach to establishing radiation weighting factors for use in assessing impact to non-human biota, and the challenges found in differentiating stochastic from deterministic impacts.

  1. Heart rate during conflicts predicts post-conflict stress-related behavior in greylag geese.

    Directory of Open Access Journals (Sweden)

    Claudia A F Wascher

    Full Text Available BACKGROUND: Social stressors are known to be among the most potent stressors in group-living animals. This is not only manifested in individual physiology (heart rate, glucocorticoids, but also in how individuals behave directly after a conflict. Certain 'stress-related behaviors' such as autopreening, body shaking, scratching and vigilance have been suggested to indicate an individual's emotional state. Such behaviors may also alleviate stress, but the behavioral context and physiological basis of those behaviors is still poorly understood. METHODOLOGY/PRINCIPAL FINDINGS: We recorded beat-to-beat heart rates (HR of 22 greylag geese in response to agonistic encounters using fully implanted sensor-transmitter packages. Additionally, for 143 major events we analyzed the behavior shown by our focal animals in the first two minutes after an interaction. Our results show that the HR during encounters and characteristics of the interaction predicted the frequency and duration of behaviors shown after a conflict. CONCLUSIONS/SIGNIFICANCE: To our knowledge this is the first study to quantify the physiological and behavioral responses to single agonistic encounters and to link this to post conflict behavior. Our results demonstrate that 'stress-related behaviors' are flexibly modulated by the characteristics of the preceding aggressive interaction and reflect the individual's emotional strain, which is linked to autonomic arousal. We found no support for the stress-alleviating hypothesis, but we propose that stress-related behaviors may play a role in communication with other group members, particularly with pair-partners.

    Objective: To assess the differences in relative risk of developing diabetes and CHD, obesity, fasting blood glucose, insulin and lipids of children having family history of diabetes or heart disease in first or second degree relatives as compared to control group. Design: Children were given a questionnaire to collect demographic data and to assess their dietary habits and family history. Anthropometric measurements and blood samples for fasting blood glucose, insulin and lipids of 8-10 years old children from 4 schools was taken. Subjects: Children having positive family history of diabetes (n=44) or heart disease (n=16) in first or second degree relatives were compared with a control group (n=39). Results: Children having positive family history for diabetes had slightly higher mean values for BMI, waist circumference, arm fat % as compared to the controls but the differences were not statistically significant. Overweight children (>85th Percentile of BMI for age) did not differ significantly in terms of various risk indicators however those who were in the uppermost tertile of arm fat % had significantly higher total Cholesterol, Triglycerides, LDL-C, LDL:HDL and Insulin levels (P<0.05 in each case). Conclusion: Diabetes and CVD risks from positive family history for the disease are probably mediated through increased body fat percentage. Thus even when information about family history of disease is lacking, arm-fat-percentage could be used as an important screening tool for determining the risk status of children. (author)

    Obesity, affects a third of the US population and its corollary occupant weight adversely impacts safe flight operations. Increased aircraft weight results in longer takeoff/landing distances, degraded climb gradients and airframe failure may occur in turbulence. In this study, the rate, temporal changes, and lethality of accidents in piston-powered, general aviation aircraft related to exceeding the maximum aircraft weight/center of gravity (CG) limits were determined. Nation-wide person body mass were from the National Health and Nutrition Examination Survey. The NTSB database was used to identify accidents related to operation of aircraft outside of their weight/CG envelope. Statistical analyses employed T-tests, proportion tests and a Poisson distribution. While the average body mass climbed steadily (p<0.001) between 1999 and 2014 the rate of accidents related to exceedance of the weight/CG limits did not change (p=0.072). However, 57% were fatal, higher (p<0.001) than the 21% for mishaps attributed to other causes/factors. The majority (77%) of accidents were due to an overloaded aircraft operating within its CG limits. As to the phase of flight, accidents during takeoff and those occurring enroute carried the lowest (50%) and highest (85%) proportion of fatal accidents respectively. While the rate of general aviation accidents related to operating an aircraft outside of its weight/CG envelope has not increased over the past 15 years, these types of accidents carry a high risk of fatality. Airmen should be educated as to such risks and to dispel the notion held by some that flights may be safely conducted with an overloaded aircraft within its CG limits. Copyright © 2016 Elsevier Ltd.

    Investigate the relationship between use of Nutrition Facts labels on packaged foods and weight-related behaviors. Cross-sectional survey in 2015-2016. Young adult respondents (n = 1,817; 57% women; average age 31.0 ± 1.6 years) to the Project Eating and Activity in Teens and Young Adults-IV survey, the fourth wave of a longitudinal cohort study. Use of Nutrition Facts labels on packaged foods; healthy, unhealthy, and extreme weight control behaviors; intuitive eating; binge eating. Linear and logistic regression models were adjusted for age, ethnicity/race, education, income, and weight status. In women, greater Nutrition Facts use was associated with a 23% and 10% greater likelihood of engaging in healthy and unhealthy weight control behaviors, respectively, and a 17% greater chance of engaging in binge eating. In men, greater label use was associated with a 27% and 17% greater likelihood of engaging in healthy and unhealthy weight control behaviors, respectively, and a lower level of intuitive eating. Professionals advising patients and clients on weight management may consider possible gender differences in response to weight loss and management guidance. Since label use was related to engagement in some unhealthy behaviors in addition to healthy behaviors, it is important to consider how individuals may use labels, particularly those at risk for, or engaging in, disordered eating behaviors. Future research investigating potential relationships between Nutrition Facts use, intuitive eating, and binge eating is needed. Copyright © 2017 Society for Nutrition Education and Behavior.

    Clinical and experimental conflicting data have questioned the relationship between infectious agents, inflammation and dilated cardiomyopathy (DCM). The aim of this study was to determine the frequency of infectious agents and inflammation in endomyocardial biopsy (EMB) specimens from patients with idiopathic DCM, explanted hearts from different etiologies, including Chagas' disease, compared to donated hearts. From 2008 to 2011, myocardial samples from 29 heart donors and 55 patients with DCMs from different etiologies were studied (32 idiopathic, 9 chagasic, 6 ischemic and 8 other specific etiologies). Inflammation was investigated by immunohistochemistry and infectious agents by immunohistochemistry, molecular biology, in situ hybridization and electron microscopy. There were no differences regarding the presence of macrophages, expression of HLA class II and ICAM-I in donors and DCM. Inflammation in Chagas' disease was predominant. By immunohistochemistry, in donors, there was a higher expression of antigens of enterovirus and Borrelia, hepatitis B and C in DCMs. By molecular biology, in all groups, the positivity was elevated to microorganisms, including co-infections, with a higher positivity to adenovirus and HHV6 in donors towards DCMs. This study was the first to demonstrate the presence of virus in the heart tissue of chagasic DCM. The presence of inflammation and infectious agents is frequent in donated hearts, in the myocardium of patients with idiopathic DCM, myocardial dysfunction related to cardiovascular diseases, and primary and secondary cardiomyopathies, including Chagas' disease. The role of co-infection in Chagas' heart disease physiopathology deserves to be investigated in future studies. Copyright © 2014 Elsevier Ireland Ltd. All rights reserved.

    Low adherence to guidelines for weight-related behaviours (e.g. dietary intake and physical activity) among US children underscores the need to better understand how parental factors may influence children's obesity risk. In addition to most often acting as primary caregiver to their children, women are also known to experience greater levels of stress than men. This study systematically reviewed associations between maternal stress and children's weight-related behaviours. Our search returned 14 eligible articles, representing 25 unique associations of maternal stress with a distinct child weight-related behaviour (i.e. healthy diet [n = 3], unhealthy diet [n = 6], physical activity [n = 7] and sedentary behaviour [n = 9]). Overall, findings for the relationship between maternal stress and children's weight-related behaviours were mixed, with no evidence for an association with children's healthy or unhealthy dietary intake, but fairly consistent evidence for the association of maternal stress with children's lower physical activity and higher sedentary behaviour. Recommendations for future research include prioritizing prospective designs, identifying moderators, and use of high-resolution, real-time data collection techniques to elucidate potential mechanisms. © 2017 World Obesity Federation.

    We derive the structural relations between nested harmonic sums and the corresponding Mellin transforms of Nielsen integrals and harmonic polylogarithms at weight w=6. They emerge in the calculations of massless single-scale quantities in QED and QCD, such as anomalous dimensions and Wilson coefficients, to 3- and 4-loop order. We consider the set of the multiple harmonic sums at weight six without index {l_brace}-1{r_brace}. This restriction is sufficient for all known physical cases. The structural relations supplement the algebraic relations, due to the shuffle product between harmonic sums, studied earlier. The original amount of 486 possible harmonic sums contributing at weight w=6 reduces to 99 sums with no index {l_brace}-1{r_brace}. Algebraic and structural relations lead to a further reduction to 20 basic functions. These functions supplement the set of 15 basic functions up to weight w=5 derived formerly. We line out an algorithm to obtain the analytic representation of the basic sums in the complex plane. (orig.)

  14. Neonate With Severe Heart Failure Related to Vein of Galen Malformation

    Full Text Available We report a full-term female neonate who presented with respiratory distress and severe heart failure soon after birth. Heart failure secondary to perinatal infection was initially suspected. Subsequent echocardiography revealed aortic runoff, which led to consideration of an intracranial vascular abnormality. Ultrasound and magnetic resonance imaging of the brain confirmed a diagnosis of vein of Galen aneurismal malformation (VGAM. Endovascular coil embolization of the vascular anomaly was performed, resulting in improvement of heart failure. VGAM should be considered in the differential diagnosis of neonatal congestive heart failure with a structurally normal heart. Urgent endovascular embolization and aggressive medical treatment of heart failure improve prognosis in neonatal VGAM.

    The aim of our study was to evaluate the influence of lifestyle factors and molecular biomarkers on the maintenance of the weight lost after a hypocaloric Mediterranean diet. After 3 months on a diet, patients (n = 335) remained with no controlled diet during 3 years and they were revaluated. Using linear regression, in the group of responders, we detected that a positive weight loss at 3 months, serum levels of leptin at 3 months, and each 30 min per week of physical activity were associated with weight loss maintenance. In the model with reduced weight (RW) as dependent variable, a positive weight loss at 3 months was associated with 2.4% RW (95% CI 1.31-8.11; p = 0.015), each unit of serum leptin levels at 3 months with -0.44% RW (95% CI -0.59 to -0.020; p = 0.007), each basal unit homeostasis model assessment for insulin resistance (HOMA-IR) level with -2.32% (95% CI -13.01 to -0.17; p = 0.040), and each 30 min per week of physical activity with 1.58% RW (95% CI 1.08-2.94; p = 0.020). Obese subjects who are on maintenance weight loss after a dietary intervention appear to have a better initial response during the 3 months intervention, more physical activity at 3 years, and lower basal HOMA-IR and leptin after weight loss than those who regain weight. © 2017 S.

    Cow size has been suggested to be an important consideration for selecting cattle to match their production environment. Over the last several decades, the trend in genetic selection for maximum growth has led to gradual increases in beef cow size. An unrelated trend during this same period in the western United States has been an increase in temperature, drought frequency, and drought severity. Due to the potential influence of the increasing cow size trend on nutritional maintenance costs and production, we assessed the effect of cow size on weaning weight and efficiency in relation to drought on a semiarid high-elevation ranch in Wyoming. This study addresses a lack of empirical studies on the interaction between cow size and drought. We measured calf weaning weights of 80 Angus × Gelbvieh cows from 2011 to 2014 and assessed how drought affected weaning weights, efficiency (considered as calf weight relative to cow weight), intake requirements, and potential herd sizes relative to cow size. We stratified cows into 5 weight classes (453, 498, 544, 589, and 634 kg) as a proxy for cow size and adjusted weaning weights to a 210-d calf sex adjusted value. Cow size was a significant factor every year, with different cow sizes having advantages or disadvantages different years relative to weaning weight. However, efficiency for the smallest cows (453 kg) was always greater than efficiency for largest cows (634 kg; cows was greater in the driest year (0.41 ± 0.02) than efficiency of the largest cows in the wettest years (0.37 ± 0.01). The change in efficiency (ΔE) between wet and dry years was 0.18 for the smallest cow size and 0.02 for the largest cow size, and ΔE decreased as cow size increased. This is an indication of the ability of smaller cows to lower maintenance requirements in response to changes in the production environment but with optimal upside potential when conditions are favorable. These results indicate large cows (589 to 634 kg) do not maximize

    Individuals with obesity and binge eating disorder (BED) report poorer weight-related quality of life (WRQOL) compared to individuals with obesity alone. Cognitive behavioral therapy (CBT), the best available treatment for BED, does not consistently produce weight loss or improvements in weight QOL. The purpose of the current study was to examine baseline and longitudinal associations between eating-related and psychosocial variables and dimensions of weight QOL. We examined associations between predictor variables, including body mass index (BMI), eating disorder (ED) psychopathology, and psychosocial factors, in relation to three dimensions of WRQOL among 171 patients whom received CBT for BED. Participants completed interviews and self-report measures at baseline prior to CBT and at end of treatment. At baseline the following associations were significant: BMI, ED psychopathology, and self-esteem were associated with weight-related self-esteem; gender, BMI, and self-esteem were associated with weight-related public distress (i.e., stigma and worry in public because of one's weight); and age, BMI, and ED psychopathology were associated with weight-related physical function. At end of treatment, the following associations were significant: changes in ED psychopathology and coping predicted weight-related self-esteem; changes in coping and self-esteem predicted weight-related public distress; and changes in BMI and subjective binge eating predicted weight-related physical function. Overall, changes in a number of ED and associated symptoms were associated with improvements in WRQOL. Copyright © 2017 Elsevier Ltd. All rights reserved.

  19. Addressing weight stigma in physiotherapy: Development of a theory-driven approach to (re)thinking weight-related interactions.

    In this article, we propose a theory-driven approach to developing interventions for reducing weight stigma in physiotherapy and discuss the design and exploratory trial of such an intervention. Weight stigma has been identified in physiotherapists in empirical investigations. However, there has been little consideration of how this stigma might be addressed. We highlight Goffman's work on stigma that provides social and embodied understandings of stigma. Goffman's approach, however, is notably apolitical, ahistorical and lacks mechanisms for understanding power. We suggest that post-structuralist perspectives can provide insight into these areas. Drawing on these theories, we critically examine the literature on weight stigma reduction, finding that trials have largely been unsuccessful. We argue that this may be due to overly passive and simplistic intervention designs. As context-specific understandings are desirable, we examine the nature of physiotherapy to determine what might be relevant to (re)thinking weight in this profession. We then discuss the development of a multifactorial, active weight stigma intervention we trialed with eight physiotherapists. Supported by theory, the outcomes of the exploratory study suggest that physiotherapy-specific factors such as fostering professional reflexivity and improving understandings of stigma need to be incorporated into an active intervention that considers the complex determinants of weight stigma.

  20. Structural relations of harmonic sums and Mellin transforms up to weight w=5

    2009-01-15

    We derive the structural relations between the Mellin transforms of weighted Nielsen integrals emerging in the calculation of massless or massive single-scale quantities in QED and QCD, such as anomalous dimensions and Wilson coefficients, and other hard scattering cross sections depending on a single scale. The set of all multiple harmonic sums up to weight five cover the sums needed in the calculation of the 3-loop anomalous dimensions. The relations extend the set resulting from the quasi-shuffle product between harmonic sums studied earlier. Unlike the shuffle relations, they depend on the value of the quantities considered. Up to weight w=5, 242 nested harmonic sums contribute. In the present physical applications it is sufficient to consider the sub-set of harmonic sums not containing an index i=-1, which consists out of 69 sums. The algebraic relations reduce this set to 30 sums. Due to the structural relations a final reduction of the number of harmonic sums to 15 basic functions is obtained. These functions can be represented in terms of factorial series, supplemented by harmonic sums which are algebraically reducible. Complete analytic representations are given for these 15 meromorphic functions in the complex plane deriving their asymptotic- and recursion relations. A general outline is presented on the way nested harmonic sums and multiple zeta values emerge in higher order calculations of zero- and single scale quantities. (orig.)

  1. It's all relative: The role of object weight in toddlers' gravity bias.

    2018-02-01

    Work over the past 20 years has demonstrated a gravity bias in toddlers; when an object is dropped into a curved tube, they will frequently search at a point immediately beneath the entry of the tube rather than in the object's actual location. The current study tested 2- to 3½-year-olds' (N = 88) gravity bias under consideration of object weight. They were tested with either a heavy or light ball, and they had information about either one of the balls only or both balls. Evaluating their first search behavior showed that participants generally displayed the same age trends as other studies had demonstrated, with older toddlers passing more advanced task levels by being able to locate objects in the correct location. Object weight appeared to have no particular impact on the direction of these trends. However, where weight was accessible as relative information, toddlers were younger at passing levels and older at failing levels, although significantly so only from around 3 years of age onward. When they failed levels, toddlers made significantly more gravity errors with the heavy ball when they had information about both balls and made more correct choices with the light ball. As a whole, the findings suggest that nonvisual object variables, such as weight, affect young children's search behaviors in the gravity task, but only if these variables are presented in relation to other objects. This relational information has the potential to enhance or diminish the gravity bias. Copyright © 2017 Elsevier Inc. All rights reserved.

  2. Heart Toxicity Related to Herbs and Dietary Supplements: Online Table of Case Reports. Part 4 of 5.

    Brown, Amy C

    2017-10-05

    The purpose of this review was to create an online research summary table of heart toxicity case reports related to dietary supplements (DS; includes herbs). Documented PubMed case reports of DS appearing to contribute to heart-related problems were used to create a "Toxic Table" that summarized the research (1966 to April, 2016, and cross-referencing). Keywords included "herb," "dietary supplement," and cardiac terms. Case reports were excluded if they were herb combinations (some exceptions), Chinese herb mixtures, teas of mixed herb contents, mushrooms, poisonous plants, self-harm (e.g. suicide), excess dose (except vitamins/minerals), drugs or illegal drugs, drug-herbal interactions, and confounders of drugs or diseases. The spectrum of heart toxicities included hypertension, hypotension, hypokalemia, bradycardia, tachycardia, arrhythmia, ventricular fibrillation, heart attack, cardiac arrest, heart failure, and death. Heart related problems were associated with approximately seven herbs: Four traditional Chinese medicine herbs - Don quai (Angelica sinensis), Jin bu huan (Lycopodium serratum), Thundergod vine or lei gong teng (Tripterygium wilfordii Hook F), and Ting kung teng (Erycibe henryi prain); one an Ayruvedic herb - Aswagandha, (Withania somnifera); and two North American herbs - blue cohosh (Caulophyllum thalictroides), and Yohimbe (Pausinystalia johimbe). Aconitum and Ephedra species are no longer sold in the United States. The DS included, but are not limited to five DS - bitter orange, caffeine, certain energy drinks, nitric oxide products, and a calming product. Six additional DS are no longer sold. Licorice was the food related to heart problems. The online "Toxic Table" forewarns clinicians, consumers and the DS industry by listing DS with case reports related to heart toxicity. It may also contribute to Phase IV post marketing surveillance to diminish adverse events that Government officials use to regulate DS.

    Full Text Available Because of concerns related to the use of antibiotics in animal agriculture, antibiotic-free alternatives are greatly needed to prevent disease and promote animal growth. One of the current challenges facing commercial turkey production in Minnesota is difficulty obtaining flock average weights typical of the industry standard, and this condition has been coined “Light Turkey Syndrome” or LTS. This condition has been identified in Minnesota turkey flocks for at least five years, and it has been observed that average flock body weights never approach their genetic potential. However, a single causative agent responsible for these weight reductions has not been identified despite numerous efforts to do so. The purpose of this study was to identify the bacterial community composition within the small intestines of heavy and light turkey flocks using 16S rRNA sequencing, and to identify possible correlations between microbiome and average flock weight. This study also sought to define the temporal succession of bacteria occurring in the turkey ileum. Based upon 2.7 million sequences across nine different turkey flocks, dominant operational taxonomic units (OTUs were identified and compared between the flocks studied. OTUs that were associated with heavier weight flocks included those with similarity to Candidatus division Arthromitus and Clostridium bartlettii, while these flocks had decreased counts of several Lactobacillus species compared to lighter weight flocks. The core bacterial microbiome succession in commercial turkeys was also defined. Several defining markers of microbiome succession were identified, including the presence or abundance of Candidatus division Arthromitus, Lactobacillus aviarius, Lactobacillus ingluviei, Lactobacillus salivarius, and Clostridium bartlettii. Overall, the succession of the ileum bacterial microbiome in commercial turkeys proceeds in a predictable manner. Efforts to prevent disease and promote growth in

    Intestinal ischemia-reperfusion is a frequent clinical event associated to injury in distant organs, especially the heart. To investigate the gene expression of oxidative stress and antioxidant defense in the heart of inbred mice subjected to intestinal ischemia and reperfusion (IR). Twelve mice (C57BL / 6) were assigned to: IR Group (GIR) with 60 minutes of superior mesenteric artery occlusion followed by 60 minutes of reperfusion; Control Group (CG) which underwent anesthesia and laparotomy without IR procedure and was observed for 120 minutes. Intestine and heart samples were processed using the RT-qPCR / Reverse transcriptase-quantitative Polymerase Chain Reaction method for the gene expression of 84 genes related to oxidative stress and oxidative defense (Student's 't' test, p < 0.05). The intestinal tissue (GIR) was noted to have an up-regulation of 65 genes (74.71%) in comparison to normal tissue (CG), and 37 genes (44.04%) were hyper-expressed (greater than three times the threshold allowed by the algorithm). Regarding the remote effects of intestinal I/R in cardiac tissue an up-regulation of 28 genes (33.33%) was seen, but only eight genes (9.52%) were hyper-expressed three times above threshold. Four (7.14%) of these eight genes were expressed in both intestinal and cardiac tissues. Cardiomyocytes with smaller and pyknotic nuclei, rich in heterochromatin with rare nucleoli, indicating cardiac distress, were observed in the GIR. Intestinal I/R caused a statistically significant over expression of 8 genes associated with oxidative stress in remote myocardial tissue

    of breastfeeding are unknown. OBJECTIVE: The objective was to examine how prepregnancy weight, gestational weight gain, postpartum weight changes, and breastfeeding influence maternal weight and body mass index-adjusted waist circumference (WCBMI) 7 y after delivery. DESIGN: This was a prospective cohort study......; 87% of this effect was mediated through later weight changes. For both outcomes, a small inverse association was observed for breastfeeding duration. This was strongest for WCBMI, for which 97% of the effect was direct, ie, not mediated through postpartum weight. CONCLUSIONS: These findings show...... that postpartum weight retention at 6 mo and weight gain from 6 to 18 mo postpartum contribute equally to adverse maternal anthropometric measures 7 y after delivery. Breastfeeding duration may have a beneficial effect....

    Full Text Available According to different authors, the representation of women in the structure of chronic heart failure (CHF ranges from 50% to 60%, however, in clinical studies the number of participants in the female reaches only 20–30%. Aim. To study age-related changes in the structural parameters of the heart and myocardial remodeling in CHF. 216 women of different age groups who have had CHF I–III functional class on the background of normal, overweight and abdominal obesity I–III degree were examined. Methods and results. Structural parameters of the heart and the condition of cardiac remodeling were estimated with echocardiography. Found that in CHF in women with overweight and obesity with age increasing is a more significant dilatation of cardiac chambers, myocardial hypertrophy of the left ventricle and the calcination of valve apparatus. In most cases myocardial remodeling were presented by concentric hypertrophy of the left ventricle. Conclusion. This demonstrates negative impact of increasing age on the restructuring of the heart in conditions of CHF in women with overweight and obesity.

    Childhood central nervous system tumor survivors (CCNSTS) are at risk for adverse health issues. Little research has been conducted to explore the role of parental factors in weight management to mitigate adverse health outcomes. We conducted 9 group interviews (n=20) with CCNSTS, their parents, and health care providers to ascertain parental factors that may influence weight management practices in CCNSTS. Three main themes were identified: parenting style, parent-child connectedness, and food and physical activity (PA) environment. Although most parents adopted an authoritative parenting style related to diet and PA practices, some adopted a permissive parenting style. Participants expressed high levels of connection that may hinder the development of peer relationships and described the food and PA environments that promote or hinder weight management through parental modeling of healthy eating and PA and access to healthy food and activities. Weight management interventions for CCNSTS may experience greater benefit from using a family-focused approach, promoting positive food and PA environments, parental modeling of healthy eating and exercise, and partnering with youth to adopt weight management behaviors.

    Background Since improved treatment of congestive heart failure has resulted in decreased mortality and hospitalisation rates, increasing self-perceived health-related quality of life (HRQoL) has become a major goal of congestive heart failure treatment. However, an overview on predictieve factors of HRQoL is currently lacking in literature. Purpose The aim of this study was to identify key factors associated with HRQoL in stable ambulatory patients with congestive heart failure. Methods A systematic review was performed. MEDLINE, Web of Science and Embase were searched for the following combination of terms: heart failure, quality of life, health perception or functional status between the period 2000 and February 2017. Literature screening was done by two independent reviewers. Results Thirty-five studies out of 8374 titles were included for quality appraisal, of which 29 were selected for further data extraction. Four distinct categories grouping different types of variables were identified: socio-demographic characteristics, clinical characteristics, health and health behaviour, and care provider characteristics. Within the above-mentioned categories the presence of depressive symptoms was most consistently related to a worse HRQoL, followed by a higher New York Heart Association functional class, younger age and female gender. Conclusion Through a systematic literature search, factors associated with HRQoL among congestive heart failure patients were investigated. Age, gender, New York Heart Association functional class and depressive symptoms are the most consistent variables explaining the variance in HRQoL in patients with congestive heart failure. These findings are partly in line with previous research on predictors for hard endpoints in patients with congestive heart failure.

    With the advent of large data age, power system research has entered a new stage. At present, the main application of large data in the power system is the early warning analysis of the power equipment, that is, by collecting the relevant historical fault data information, the system security is improved by predicting the early warning and failure rate of different kinds of equipment under certain relational factors. In this paper, a method of line failure rate warning is proposed. Firstly, fuzzy dynamic clustering is carried out based on the collected historical information. Considering the imbalance between the attributes, the coefficient of variation is given to the corresponding weights. And then use the weighted fuzzy clustering to deal with the data more effectively. Then, by analyzing the basic idea and basic properties of the relational analysis model theory, the gray relational model is improved by combining the slope and the Deng model. And the incremental composition and composition of the two sequences are also considered to the gray relational model to obtain the gray relational degree between the various samples. The failure rate is predicted according to the principle of weighting. Finally, the concrete process is expounded by an example, and the validity and superiority of the proposed method are verified.

    To examine how self-reported sleep quality and daytime symptoms are associated with selected domains of cognitive function among individuals with heart failure (HF). HF patients suffer from poor sleep quality and cognitive decline. The relationship between sleep and cognition has not been well documented among individuals with HF. In this descriptive, cross-sectional study, 68 individuals with HF (male: 63%, mean age = 72 years, SD = 11) completed sleep questionnaires and a neuropsychological battery. Participant had mean Pittsburgh Sleep Quality Index score of 5.04 (SD = 2.8). Regression analyses demonstrated neither sleep quality or excessive daytime sleepiness (EDS) were related to cognitive function, but daytime dysfunction was related to lower letter fluency and attention index. Contrary to some earlier reports, subjective sleep and EDS in this group of individuals was not associated with cognitive decline. Copyright © 2015 Elsevier Inc. All rights reserved.

    Background Cumulative exposure to lead is associated with cardiovascular outcomes. Polymorphisms in the δ-aminolevulinic acid dehydratase (ALAD), hemochromatosis (HFE), heme oxygenase-1 (HMOX1), vitamin D receptor (VDR), glutathione S-transferase (GST) supergene family (GSTP1, GSTT1, GSTM1), apolipoprotein E (APOE),angiotensin II receptor-1 (AGTR1) and angiotensinogen (AGT) genes, are believed to alter toxicokinetics and/or toxicodynamics of lead. Objectives We assessed possible effect modification by genetic polymorphisms in ALAD, HFE, HMOX1, VDR, GSTP1, GSTT1, GSTM1, APOE, AGTR1 and AGT individually and as the genetic risk score (GRS) on the association between cumulative lead exposure and incident coronary heart disease (CHD) events. Methods We used K-shell-X-ray fluorescence to measure bone lead levels. GRS was calculated on the basis of 22 lead-related loci. We constructed Cox proportional hazard models to compute adjusted hazard ratios (HRs) and 95% confidence intervals (CIs) for incident CHD. We applied inverse probability weighting to account for potential selection bias due to recruitment into the bone lead sub-study. Results Significant effect modification was found by VDR, HMOX1, GSTP1, APOE, and AGT genetic polymorphisms when evaluated individually. Further, the bone lead-CHD associations became larger as GRS increases. After adjusting for potential confounders, a HR of CHD was 2.27 (95%CI: 1.50–3.42) with 2-fold increase in patella lead levels, among participants in the top tertile of GRS. We also detected an increasing trend in HRs across tertiles of GRS (p-trend = 0.0063). Conclusions Our findings suggest that lead-related loci as a whole may play an important role in susceptibility to lead-related CHD risk. These findings need to be validated in a separate cohort containing bone lead, lead-related genetic loci and incident CHD data. PMID:27584680

    A higher tolerance for a larger body size has been associated with obesity in black South African (SA) women. The aim of the present study was to explore perceptions regarding body size and weight loss in a sample of black women from a low-income community in Cape Town, SA. Qualitative pilot study including five focus groups. Data were analysed using thematic analysis. Khayelitsha, Cape Town, SA. Twenty-one black SA women. The majority of participants had positive perceptions of overweight/obesity, which were influenced by community and cultural perceptions, but some inconsistencies were observed as overweight/obesity was also associated with ill health. Participants identified many benefits to weight loss, but due to the association with sickness, they were concerned about being stigmatised in their community. Although participants had knowledge about healthy eating, the main barrier to eating healthily included the perceived higher cost of healthier food and food insecurity. All participants saw exercise as a strategy to lose weight and improve health, and were interested in participating in a community-based exercise intervention, but negative community perceptions and conflicting views regarding who should lead the intervention were identified as barriers. These findings highlight the complexities surrounding participants' perceptions regarding body size, weight loss and weight-loss interventions, and emphasise low socio-economic status as a barrier to change. The study also highlights the strong influence of cultural ideals and community perceptions on personal perceptions. These findings underscore the necessity for culturally appropriate weight-loss interventions in low-income, transitioning communities.

    Quantifying resource utilization in the inpatient care of congenital heart diease is clinically relevant. Our purpose is to measure the investment of inpatient care resources to achieve survival in hypoplastic left heart syndrome (HLHS), and to determine how much of that investment occurs in hospitalizations that have a fatal outcome, the mortality-related resource utilization fraction (MRRUF). A collaborative administrative database, the Pediatric Health Information System (PHIS) containing data for 43 children's hospitals, was queried by primary diagnosis for HLHS admissions of patients ≤21 years old during 2004-2013. Institution, patient age, inpatient deaths, billed charges (BC) and length of stay (LOS) were recorded. In all, 11,122 HLHS admissions were identified which account for total LOS of 277,027 inpatient-days and $3,928,794,660 in BC. There were 1145 inpatient deaths (10.3%). LOS was greater among inpatient deaths than among patients discharged alive (median 17 vs. 12, p providers and consumers that current practices often result in major resource expenditure for inpatient care of HLHS that does not result in survival to hospital dismissal. They highlight the need for data-driven critical review of standard practices to identify patterns of care associated with success, and to modify approaches objectively.

    Full Text Available The present study aimed to investigate whether cardiac autonomic dysfunction in aging human might be related to an underlying thyroid disturbance. ageing has been associated with hypothyroidism and cardiac autonomic dysfunction. On the basis of body mass index (BMI, 150 patients were grouped into three groups (n = 50 48 years ± 2, 55 years ± 2 and 63 years ± 2. Electrocardiogram was recorded using PowerLab system and the time and frequency domain measures of heart rate variability (HRV were calculated. Fasting blood samples were drawn for measurement of serum thyroid stimulating hormone (TSH, total thyroxin (T4 and total triiodothyronine (T3 concentrations. The levels of TSH, T4 and T3 were not significantly different between the groups. The frequency domain HRV parameter reflecting parasympathetic tone (high-frequency normalized units, HFnu was significantly reduced in aging third groups group. The parameters which reflect sympathetic activation (Heart rate, low-frequency normalized units; LFnu and the LF/HF ratio were significantly increased in the aging group. HFnu was significantly and negatively correlated with age, whereas LFnu and LF/HF ratio were significantly and positively correlated with the above mentioned parameters. No significant relationships were noted between the HRV parameters and the levels of TSH or thyroid hormones. Cardiac autonomic dysfunction in aging human is not linked with underlying thyroid disturbance.

    Full Text Available This study identified factors affecting health related quality of life (HRQOL in 300 hospitalized patients with heart failure (HF. Data were collected by the completion of a questionnaire which included patients’ characteristics and the Minnesota Living with Heart Failure Questionnaire (MLHFQ. Analysis of data showed that the median of the total score of MLHFQ was 46 and the median of the physical and mental state was 22 and 6, respectively. Also, participants who were householders or had “other” professions had lower score of 17 points and therefore better quality of life compared to patients who were civil/private employees (p<0.001 and p<0.001, resp.. Patients not receiving anxiolytics and antidepressants had lower quality of life scores of 6 and 15.5 points, respectively, compared to patients who received (p=0.003 and p<0.001, resp.. Patients with no prior hospitalization had lower score of 7 points compared to those with prior hospitalization (p=0.002, whereas patients not retired due to the disease had higher score of 7 points (p=0.034. Similar results were observed for the physical and mental state. Improvement of HF patients’ quality of life should come to the forefront of clinical practice.

    Administrative data are increasingly used to evaluate clinical outcomes and quality of care in pediatric congenital heart surgery (CHS) programs. Several published analyses of large pediatric administrative data sets have relied on the All Patient Refined Diagnosis Related Groups (APR-DRG, version 24) diagnostic classification system. The accuracy of this classification system for patients undergoing CHS is unclear. We performed a retrospective cohort study of all 14,098 patients 0 to 5 years of age undergoing any of six selected congenital heart operations, ranging in complexity from isolated closure of a ventricular septal defect to single-ventricle palliation, at 40 tertiary-care pediatric centers in the Pediatric Health Information Systems database between 2007 and 2010. Assigned APR-DRGs (cardiac versus noncardiac) were compared using χ2 or Fisher's exact tests between those patients admitted during the first day of life versus later and between those receiving extracorporeal membrane oxygenation support versus those not. Recursive partitioning was used to assess the greatest determinants of APR-DRG type in the model. Every patient admitted on day 1 of life was assigned to a noncardiac APR-DRG (pDRG (pDRG experienced a significantly increased mortality (pDRG coding has systematic misclassifications, which may result in inaccurate reporting of CHS case volumes and mortality.

    Statistical and clinical reports indicate that betel nut chewing is strongly associated with progression of oral cancer because some ingredients in betel nuts are potential cancer promoters, especially arecoline. Early diagnosis for cancer biomarkers is the best strategy for prevention of cancer progression. Several methods are suggested for investigating cancer biomarkers. Among these methods, gel-based proteomics approach is the most powerful and recommended tool for investigating biomarkers due to its high-throughput. However, this proteomics approach is not suitable for screening biomarkers with molecular weight under 10 KDa because of the characteristics of gel electrophoresis. This study investigated biomarkers with molecular weight under 10 KDa in rats with arecoline challenge. The centrifuging vials with membrane (10 KDa molecular weight cut-off) played a crucial role in this study. After centrifuging, the filtrate (containing compounds with molecular weight under 10 KDa) was collected and spotted on a sample plate for MALDI-TOF mass spectrometry analysis. Compared to control, three extra peaks (m/z values were 1553.1611, 1668.2097 and 1740.1832, respectively) were found in sera and two extra peaks were found in heart tissue samples (408.9719 and 524.9961, respectively). These small compounds should play important roles and may be potential biomarker candidates in rats with arecoline. This study successfully reports a mass-based method for investigating biomarker candidates with small molecular weight in different types of sample (including serum and tissue). In addition, this reported method is more time-efficient (1 working day) than gel-based proteomics approach (5~7 working days).

    Cancer constitutes a momentous health burden in our society. Critical information on cancer may be hidden in its signaling pathways. However, even though a large amount of money has been spent on cancer research, some critical information on cancer-related signaling pathways still remains elusive. Hence, new works towards a complete understanding of cancer-related signaling pathways will greatly benefit the prevention, diagnosis, and treatment of cancer. We propose the node-weighted Steiner tree approach to identify important elements of cancer-related signaling pathways at the level of proteins. This new approach has advantages over previous approaches since it is fast in processing large protein-protein interaction networks. We apply this new approach to identify important elements of two well-known cancer-related signaling pathways: PI3K/Akt and MAPK. First, we generate a node-weighted protein-protein interaction network using protein and signaling pathway data. Second, we modify and use two preprocessing techniques and a state-of-the-art Steiner tree algorithm to identify a subnetwork in the generated network. Third, we propose two new metrics to select important elements from this subnetwork. On a commonly used personal computer, this new approach takes less than 2 s to identify the important elements of PI3K/Akt and MAPK signaling pathways in a large node-weighted protein-protein interaction network with 16,843 vertices and 1,736,922 edges. We further analyze and demonstrate the significance of these identified elements to cancer signal transduction by exploring previously reported experimental evidences. Our node-weighted Steiner tree approach is shown to be both fast and effective to identify important elements of cancer-related signaling pathways. Furthermore, it may provide new perspectives into the identification of signaling pathways for other human diseases.

    Strong evidence linking poor diet and lack of physical activity to risk of obesity and related chronic disease has supported the development and promotion of guidelines to improve population health. Still, obesity continues to escalate as a major health concern, and so the impact of weight-related guidelines on behaviour is unclear. The aim of this review was to examine consumer response to weight-related guidelines. A systematic literature search was performed using Medline, PsycInfo, ProQuest Central and additional searches using Google and reference lists. Of the 1,765 articles identified, 46 relevant titles were included. Most studies examined attitudes towards content, source, tailoring and comprehension of dietary guidelines. Many respondents reported that guidelines were confusing, and that simple, clear, specific, realistic, and in some cases, tailored guidelines are required. Recognition of guidelines did not signify understanding nor did perceived credibility of a source guarantee utilization of guidelines. There was a lack of studies assessing: the impact of guidelines on behaviour; responses to physical activity guidelines; responses among males and studies undertaken in developing countries. Further research is needed, in particular regarding responses to physical activity guidelines and guidelines in different populations. Communication professionals should assist health professionals in the development of accurate and effective weight-related guidelines. © 2012 The Authors. obesity reviews © 2012 International Association for the Study of Obesity.

    To review the criteria and 'other' considerations used internationally for prioritizing new health technologies, and to demonstrate a conjoint-analysis methodology (also known as discrete choice experiments) for deriving relative weights for the criteria. We searched the literature for criteria and other considerations for prioritizing new technologies. A convenience sample of 74 respondents completed a conjoint-analysis survey involving criteria related to technologies' 'benefits'. Encompassing 11 countries and the US state of Oregon, we were able to distinguish three main groups of criteria: (a) Need, appropriateness and clinical benefits; (b) Efficiency (including cost-effectiveness); and (c) Equality, solidarity and other ethical or social values. For several countries, the quality of the clinical and economic evidence and factors related to strategic issues and procedural justice respectively are also considered. The criteria and their weights from the conjoint-analysis survey are: 'Lives saved'=0.343, 'Life-prolongation benefits'=0.243, 'Quality-of-life gains'=0.217, a criterion representing the availability of alternative treatments=0.107, and 'Other important social/ethical benefits'=0.087. The criteria represent a pluralistic combination of needs-based, maximizing and egalitarian principles, and we demonstrated a methodology for deriving the weights for criteria related to technologies' 'benefits'.

    Health-related quality of life and functional performance are important outcome measures following heart transplantation. This study investigates the impact of pre-transplant functional performance and post-transplant rejection episodes, obesity and osteopenia on post-transplant health-related quality of life and functional performance. Functional performance and health-related quality of life were measured in 70 adult heart transplant recipients. A composite health-related quality of life outcome measure was computed via principal component analysis. Iterative, multiple regression-based path analysis was used to develop an integrated model of variables that affect post-transplant functional performance and health-related quality of life. Functional performance, as measured by the Karnofsky scale, improved markedly during the first 6 months post-transplant and was then sustained for up to 3 years. Rejection Grade > or =2 was negatively associated with health-related quality of life, measured by Short Form-36 and reversed Psychosocial Adjustment to Illness Scale scores. Patients with osteopenia had lower Short Form-36 physical scores and obese patients had lower functional performance. Path analysis demonstrated a negative direct effect of obesity (beta = - 0.28, p or =2 had a negative direct effect on this measure (beta = -0.29, p < 0.05). Either directly or through effects mediated by functional performance, moderate-to-severe rejection, obesity and osteopenia negatively impact health-related quality of life. These findings indicate that efforts should be made to devise immunosuppressive regimens that reduce the incidence of acute rejection, weight gain and osteopenia after heart transplantation.

    Introduction HBO’s Weight of the Nation was a collaborative effort among several national organizations to raise awareness about the complexity of the obesity epidemic and promote action through media and community forums. The primary aim of this study was to assess the short-term effects of Weight of the Nation community screenings on obesity-related beliefs, intentions, and policy support. Methods Five Prevention Research Centers across the U.S. administered surveys at nine Weight of the Nation community screenings between September 2012 and May 2013. Adults aged ≥18 years who completed pre–post surveys were included. The survey assessed demographic information, perceptions of the documentary, efficacy to take action and influence policies that affect obesity, intentions to take actions to support a healthy weight, and positions on policy changes that impact food systems. Data were analyzed in 2015. Results A convenience sample of 442 individuals completed surveys. The sample was mostly health workers, female, college educated, aged 25–44 years, and racially and ethnically diverse. Significant increases (p<0.001) were observed for perceived self- and collective efficacy that individuals and communities can influence policies and environmental factors that affect obesity, intentions to take actions that contribute to a healthy weight, and support for policies that change the food system. Conclusions A broad, nationwide effort, such as Weight of the Nation, that combines media with opportunities to bring community members together for discussion, may play a role in influencing beliefs, intentions, and policy support regarding obesity prevention.

    To examine the relationship of body weight to satisfaction with care in adolescents, and to obtain qualitative data on preferences for general and weight-related medical care in normal weight and overweight adolescents. The Weight and its Relationship to Adolescent Perceptions of their Providers survey, a 4-page questionnaire containing previously validated satisfaction scales and open-ended qualitative questions regarding health care preferences, was administered to 62 severely overweight (body mass index [BMI] 38.9 +/- 8.4 kg/m2) and 29 normal weight (BMI 22.5 +/- 4.0 kg/m2) adolescents (age 13.9 +/- 1.7 years; 57% female; 50% Caucasian, 47% African-American, 3% Hispanic). The affective subscale of the medical satisfaction scale was negatively correlated with BMI standard deviation score (r = -.22, p teens. Seventy-nine percent of overweight adolescents stated their health care provider discussed their weight with them; however, only 41% of overweight adolescents desired to discuss their weight. Compared to normal-weight adolescents, overweight teens were more likely to report that their provider raised topics of weight (p teens expressed concerns regarding the public location of their provider's office scale. Satisfaction with affective aspects of the provider-patient relationship is negatively correlated with BMI standard deviation score. Length of experience with one's provider is also a strong predictor of teen satisfaction with their medical care. Teens prefer the term "overweight" for those with high body weight. Sensitivity to confidentiality, privacy, and embarrassment regarding physical examination and weight are important for teen satisfaction.

    The current study was conducted to evaluate the impacts of using tibia ash percentage or ash weight as the response criteria on estimated phytase relative equivalence. Straight run broilers were fed treatment (Trt) diets from 7 to 21 d age (6 birds/pen, 8 pens/Trt). The corn-soy based Trt were formulated to contain 0.80% Ca and 4 non-phytate phosphorus (nPP) concentrations (0.20, 0.27, 0.34, and 0.40%). Monocalcium phosphate was the inorganic phosphate source added to achieve 4 different dietary nPP concentrations and against which the nPP relative equivalence of phytase was determined. A 6-phytase (Danisco Animal Nutrition, DuPont Industrial Biosciences, Marlborough, UK) was added at 500 or 1,000 phytase unit ( FTU: )/kg to the 0.20% nPP diet resulting 6 total Trts. Tibia ash was determined at 21 d age. Phytase fed at 500 or 1,000 FTU/kg increased tibia ash weight and ash percentage compared to that of birds fed 0.20% nPP diet without phytase (Pphytase nPP relative equivalence. The R2 obtained from pen value regressions were 0.81 and 0.84, for tibia ash weight and percentage, respectively. Ash percentage from birds fed 500 and 1,000 FTU phytase/kg fell within the range obtained with the MCP additions. Ash weight (842 mg/tibia) from birds fed 1,000 FTU phytase/kg exceeded (Pphytase/kg Trt. The nPP relative equivalence in birds fed 500 FTU phytase/kg were 0.117 and 0.168% based on ash percentage and weight, respectively (Pphytase/kg was 0.166% for ash percentage. Results suggested that ash weight better reflects the amount of bone mineralization as compared to ash percentage and using ash percentage may lead to an underestimation of phytase efficacy. © 2015 Poultry Science Association Inc.

    Although protection against necrosis has been observed in both hibernating (HIB) and ischemic preconditioned hearts in the second window of protection (SWOP), a comparison of the mitochondrial proteome between the two entities has not been previously performed. Anesthetized swine underwent instrumentation with a fixed constrictor around the LAD artery and were followed for 12 weeks (HIB; N=7). A second group of anesthetized swine underwent ischemic preconditioning by inflating a balloon within the LAD artery 10 times for 2 min, each separated by 2 min reperfusion and were sacrificed 24h later (SWOP; N=7). Myocardial blood flow and high-energy nucleotides were obtained in the LAD region and normalized to remote regions. Post-sacrifice, protein content as measured with iTRAQ was compared in isolated mitochondria from the LAD area of a Sham heart. Basal regional blood flow in the LAD region when normalized to the remote region was 0.86±0.04 in HIB and 1.02±0.02 in SWOP tissue (Pregional blood flows in HIB hearts, ATP content in the LAD region, when normalized to the remote region was similar in HIB versus SWOP (1.06±0.06 and 1.02±0.05 respectively; NS) as was the transmural phosphocreatine (PCr) to ATP ratio (2.1±0.2 and 2.2±0.2 respectively; NS). Using iTRAQ, 64 common proteins were identified in HIB and SWOP hearts. Compared with SWOP, the relative abundance of mitochondrial proteins involved with electron transport chain (ETC) were reduced in HIB including NADH dehydrogenase, Cytochrome c reductase and oxidase, ATP synthase, and nicotinamide nucleotide transhydrogenase. Within chronically HIB heart tissue with reduced blood flow, the relative abundance of mitochondrial ETC proteins is decreased when compared with SWOP tissue. These data support the concept that HIB heart tissue subjected to chronically reduced blood flow is associated with a down-regulation in the expression of key mitochondrial proteins involved in electron transport.

    The aim of this study was to investigate which GIS-based measures of walkability (density, land-use mix, connectivity and walkability indexes) in urban and suburban neighbourhoods are used in research and which of them are consistently associated with walking and cycling for transport, overall active transportation and weight-related measures in adults. A systematic review of English publications using PubMed, Science Direct, Active Living Research Literature Database, the Transportation Research Information Service and reference lists was conducted. The search terms utilised were synonyms for GIS in combination with synonyms for the outcomes. Thirty-four publications based on 19 different studies were eligible. Walkability measures such as gross population density, intersection density and walkability indexes most consistently correlated with measures of physical activity for transport. Results on weight-related measures were inconsistent. More research is needed to determine whether walkability is an appropriate measure for predicting weight-related measures and overall active transportation. As most of the consistent correlates, gross population density, intersection density and the walkability indexes have the potential to be used in planning and monitoring.

    Full Text Available Arsenic is one of the most toxic elements that can be found in the environment. Excessive uptake of arsenic may cause physiological changes in plants. The aim of the study was to investigate the effect of different arsenic treatments on relative chlorophyll content and dry weight of shoot and root of maize and sunflower in the early phases of plant development. Seedlings were grown in climatic room in nutrient solution under strictly regulated environmental conditions. The plants were exposed to 3, 10 and 30 mg kg-1arsenic, whereas there was no arsenic treatment on the control plants. We applied arsenic in the form of arsenite (NaAsO2 and arsenate (KH2AsO4, respectively. After 14 days of arsenic treatments, changes in relative chlorophyll content and dry weight of maize shoots and roots were recorded. In the case of sunflower these physiological parameters were measured after 21 day. The applied arsenic decreased the relative chlorophyll content of maize and sunflower leaves, especially at concentration of30 mg kg-1. The increasing amount of As treatment were resulted the lower weight of the experimental plants, which was more considerable in the case of the roots. The results indicate that the sunflower plants is more sensitive to arsenic toxicity than maize plants and all data demonstrate that the As(III is more toxic to these crop plants than the As(V.

    The coronary collateral vessels have revealed their significance in terms of reduction of infarct size, preservation left ventricular function, and prevention of left ventricular aneurysm in patients with myocardial infarction. The purpose of this study were to evaluated the relation between collateral circulation and 99m Tc-MIBI Heart SPECT in patient with acute myocardial infarction and their clinical significance. The fifty six MI patients with antegrade TIMI perfusion grade 0 and 1 were studied. The patients were classified into two groups; Group I included 30 patients with grade 2, 3 Collateral flow. Group II included 26 patients with grade 0, 1 Collateral flow. Collateral filling were graded from 0 to 3; 0- none, 1- Filling of side branch only, 2- Partial filling of the epicardial segment, 3- Complete filling of epicardial segment. Clinical variables, left ventricular function, 99m Tc-MIBI Heart SPECT were analyzed with angiographic finding. Results were following: 1) Collateral visualization was found to be greater in patient with involvement of right coronary artery (RCA). The collateral development site of infarct related artery was RCA 15 cases, left anterior descending artery (LAD) 10 cases, left circumflex artery (LCX) 5 cases, and the collateral circulation from LAD to RCA was 13 cases (40.6%). 2) There was a tendency to be decreased in peak CK activity with group I . 3) The presence of good collateral channels was more frequently 99m Tc-MIBI reversible perfusion defect (83.4% vs 15.3%, p 99m Tc-MlBI reversible perfusion defect.

    Full Text Available Abstract Background Being born with low birth weight may have an impact on different aspects of mental health, psychosocial functioning and well-being; however results from studies in young adulthood have so far yielded mixed findings. The aim of this study was to assess the long-term impact in young adulthood on self-reported mental health, health-related quality of life, self-esteem and social relations by investigating differences between two low birth weight groups and a control group. Methods In a follow-up at 20 years of age, 43 preterm VLBW (birth weight ≤ 1500 g, 55 term SGA (birth weight  Results The VLBW and SGA groups reported significantly more mental health problems than controls. The VLBW group predominantly had internalizing problems, and the non-significant association with ASR Total score was reduced by the Intelligence Quotient (IQ. The SGA group had increased scores on both internalizing and externalizing problems, and the association with ASR Total score remained significant after adjusting for IQ in this group. Both low birth weight groups reported less interaction with friends and lower quality of life related to mental health domains than controls. Self-esteem scores were lower than in the control group for athletic competence (VLBW and social acceptance (SGA. Conclusion Our findings suggest that self-reported mental health and well-being in young adulthood may be adversely affected by low birth weight, irrespective of whether this is the result of premature birth or being born SGA at term.

    Genetic factors and the prenatal environment contribute to birth weight. However, very few types of study design can disentangle their relative contribution. To examine maternal genetic and intrauterine contributions to offspring birth weight and head circumference. To compare the contribution of maternal and paternal genetic effects. Mothers and fathers were either genetically related or unrelated to their offspring who had been conceived by in vitro fertilization. 423 singleton full term offspring, of whom 262 were conceived via homologous IVF (both parents related), 66 via sperm donation (mother only related) and 95 via egg donation (father only related). Maternal weight at antenatal booking, current weight and maternal height. Paternal current weight and height were all predictors. Infant birth weight and head circumference were outcomes. Genetic relatedness was the main contributing factor between measures of parental weight and offspring birth weight as correlations were only significant when the parent was related to the child. However, there was a contribution of the intrauterine environment to the association between maternal height and both infant birth weight and infant head circumference as these were significant even when mothers were unrelated to their child. Both maternal and paternal genes made contributions to infant birth weight. Maternal height appeared to index a contribution of the intrauterine environment to infant growth and gestational age. Results suggested a possible biological interaction between the intrauterine environment and maternal inherited characteristics which suppresses the influence of paternal genes. 2010 Elsevier Ltd.

    African Americans have the highest rate of obesity in the United States relative to other ethnic minority groups. Bioecological factors including neighborhood social and physical environmental variables may be important predictors of weight-related measures specifically body mass index (BMI) in African American adults. Baseline data from the Positive Action for Today's Health (PATH) trial were collected from 417 African American adults. Overall a multiple regression model for BMI was significant, showing positive associations with average daily moderate-to-vigorous physical activity (MVPA) (B =-.21, Psocial interaction (B =-.13, Psocial interaction was associated with healthier BMI, highlighting it as a potential critical factor for future interventions in underserved, African American communities.

    Twin anemia-polycythemia sequence (TAPS) is a newly described form of chronic twin transfusion. Previous observational studies noted a discordance between birth weight and individual placental share in TAPS. The purpose of this study was to investigate if fetal growth in monochorionic (MC) twins with TAPS is determined by placental share or by the net inter-twin blood transfusion. All consecutive MC twin placentas of live-born twin pairs with and without TAPS examined at our center between June 2002 and February 2014 were included in this study. Hemoglobin (Hb) levels and individual placental share were evaluated at birth and correlated with birth weight share. We excluded MC twin pregnancies with twin-twin transfusion syndrome. A total of 270 MC twin pregnancies (TAPS group, n = 20; control group without TAPS, n = 250) were included in this study. Donors with TAPS had a lower birth weight than recipients in 90% (18/20) of cases, but a larger placental share in 65% (13/20) of cases. In the TAPS group, birth weight share was positively correlated with Hb share at birth (P < 0.01) but not with placental share (P = 0.54). In the control group without TAPS, birth weight share was strongly correlated with placental share (P < 0.01) but not with Hb share (P = 0.14). A relatively larger placental share may enable the survival of the anemic twin in TAPS. In contrast with uncomplicated MC twins, fetal growth in MC twins with TAPS is determined primarily by the net inter-twin blood transfusion instead of placental share. Copyright © 2014 Elsevier Ltd.

    A cost-utility study of a human papilloma virus (HPV) vaccine requires that the utility weights for HPV-related health states (i.e., cervical intraepithelial neoplasia (CIN), cervical cancer, and condyloma) be evaluated. The aim of the present study was to determine the utility weights for HPV-related health states. Hypothetical standardised health states related to HPV were developed based on patient education material and previous publications. To fully reflect disease progression from diagnosis to prognosis, each health state comprised four parts (diagnosis, symptoms, treatment, and progression and prognosis). Nine-hundred members from the Korean general population evaluated the HPV-related health states using a visual analogue scale (VAS) and a standard gamble (SG) approach, which were administered face-to-face via computer-assisted interview. The mean utility values were calculated for each HPV-related health state. According to the VAS, the highest utility (0.73) was HPV-positive status, followed by condyloma (0.66), and CIN grade I (0.61). The lowest utility (0.18) was cervical cancer requiring chemotherapy without surgery, followed by cervical cancer requiring chemoradiation therapy (0.42). SG revealed that the highest utility (0.83) was HPV-positive status, followed by condyloma (0.78), and CIN grade I (0.77). The lowest utility (0.43) was cervical cancer requiring chemotherapy without surgery, followed by cervical cancer requiring chemoradiation therapy (0.60). This study was based on a large sample derived from the general Korean population; therefore, the calculated utility weights might be useful for evaluating the economic benefit of cancer screening and HPV vaccination programs.

    Objective Primary care providers should counsel overweight patients to lose weight. Rates of self-reported weight-related counseling vary, perhaps due to self-report bias. We assessed accuracy and congruence of weight-related discussions among patients, physicians, and audio-recorded encounters. Methods We audio recorded encounters between physicians (n=40) and their overweight/obese patients (n=461) at five community-based practices. We coded weight-related content and surveyed patients and physicians immediately after the visit. Generalized linear mixed models assessed factors associated with accuracy. Results Overall, accuracy was moderate: patient (67%), physician (70%), and congruence (62%). When encounters contained weight-related content were analyzed, patients (98%) and physicians (97%) were highly accurate and congruent (95%) but when weight was not discussed patients and physicians were more inaccurate and incongruent (patient 36%; physician 44%; 28% congruence). Physicians less comfortable discussing weight were more likely to misreport that weight was discussed [OR = 4.5 (95% CI=1.88–10.75, p<0.001)]. White physicians with African-American patients were more likely to report accurately no discussion about weight than White physicians with White patients OR=0.30 (95% CI=0.13–0.69, p<0.01). Conclusion Physician and patient self-report of weight-related discussions were highly accurate and congruent when audio-recordings indicated weight was discussed, but not when recordings indicated no weight discussions. Physician overestimation of weight discussions when weight is not discussed constitutes missed opportunities for health interventions. PMID:24390888

    The importance of the relative dietary content of protein, carbohydrate and the type of carbohydrate (that is, glycemic index (GI)) for weight control under ad libitum conditions has been controversial owing to the lack of large scale studies with high diet adherence. The Diet, Obesity and Genes...... (DioGenes) European multicentre trial examined the importance of a slight increase in dietary protein content, reduction in carbohydrate and the importance of choosing low (LGI) vs high GI (HGI) carbohydrates for weight control in 932 obese families. Only the adults underwent a diet of 800 kcal per day...... for 8 weeks, and after losing ~11kg they were randomized to one of five energy ad libitum diets for 6 months. The diets differed in protein content and GI. The high-protein (HP) diet groups consumed 5.4% points more energy from protein than the normal protein (NP) groups, and the LGI diet groups...

    Background Body weight concerns are common among individuals with eating disorders, and this construct can be assessed using psychometric instruments. The Weight Concerns Scale (WCS) is commonly used to assess body weight concerns. Aims To evaluate the psychometric properties of the WCS with Brazilian, Portuguese, and Mozambican female college students; to estimate body weight concerns; and to identify factors related to eating disorders. Methods Confirmatory factor analysis was performed. Factorial, convergent, concurrent, and divergent validity, as well as reliability, were assessed. Cross-national invariance was tested by means of multigroup analysis. Structural models were tested using the WCS as the dependent variable, while demographic and academic variables and body mass index were used as independent variables. Logistic models were tested to estimate the likelihood of eating disorders being developed in specific groups. Results Participants were 2,068 female students. The psychometric properties of the WCS were adequate for the Portuguese sample; however, for the Brazilian and Mozambican samples, it was necessary to correlate the errors of two items to improve model fit. The WCS did not show cross-national invariance. The variables “thoughts about dropping out of college,” “medication use because of studies,” “medication and supplements use for body change,” “body mass index,” “socioeconomic status,” “age,” and “performance in course” were significant predictors of body weight concerns. Overall, 24.4% (95% confidence interval = 22.9–26.7) of the students were likely to develop eating disorders. Students under 21 years old, who use medication and supplements for body change, and who were classified as overweight/obese have increased likelihood of developing eating disorders. Conclusion The WCS showed good psychometric properties with Brazilian, Portuguese, and Mozambican students; however, it did not show cross

    This study examined the association between job-related behavioral characteristics and the risk of coronary heart diseases (CHD) in Japanese male police officers. Compared to office clerks, police officers exhibited greater age-related increases of the prevalence of CHD risk factors, and a clustering number of CHD risk factors was significantly higher in the group of those over 45 yr of age. Among the police officers, coronary-prone behavior was more frequent than that seen in office clerks. The police officers with coronary-prone behavior tended to engage in shift work and to work overtime more; yet they were less likely to perceive job stress and to express the relevant physical and psychological symptoms than those without coronary-prone behavior. The subjects with such behavioral characteristics had a significantly greater number of CHD risk factors. In a multiple regression analysis, coronary-prone behavior together with age, social support, walking hours per day, and amount of alcohol consumption were selected as significant determinants of a cluster of CHD risk factors. These results suggest that coronary-prone behavior may contribute to the higher prevalence of CHD risk factors in police officers via leading the long working hours and the work-related unfavorable lifestyles, such as alcohol drinking and physical inactivity.

  3. Polyphenols and Oxidative Stress in Atherosclerosis-Related Ischemic Heart Disease and Stroke

    Full Text Available Good nutrition could maintain health and life. Polyphenols are common nutrient mainly derived from fruits, vegetables, tea, coffee, cocoa, mushrooms, beverages, and traditional medicinal herbs. They are potential substances against oxidative-related diseases, for example, cardiovascular disease, specifically, atherosclerosis-related ischemic heart disease and stroke, which are health and economic problems recognized worldwide. In this study, we reviewed the risk factors for atherosclerosis, including hypertension, diabetes mellitus, hyperlipidemia, obesity, and cigarette smoking as well as the antioxidative activity of polyphenols, which could prevent the pathology of atherosclerosis, including endothelial dysfunction, low-density lipoprotein oxidation, vascular smooth muscle cell proliferation, inflammatory process by monocytes, macrophages or T lymphocytes, and platelet aggregation. The strong radical-scavenging properties of polyphenols would exhibit antioxidative and anti-inflammation effects. Polyphenols reduce ROS production by inhibiting oxidases, reducing the production of superoxide, inhibiting OxLDL formation, suppressing VSMC proliferation and migration, reducing platelet aggregation, and improving mitochondrial oxidative stress. Polyphenol consumption also inhibits the development of hypertension, diabetes mellitus, hyperlipidemia, and obesity. Despite the numerous in vivo and in vitro studies, more advanced clinical trials are necessary to confirm the efficacy of polyphenols in the treatment of atherosclerosis-related vascular diseases.

    The objective of this study was to assess the evolution and classification of body weight in relation to the results of bariatric surgery in women who underwent the procedure more than two years ago. A total of 141 women underwent banded Roux-en-Y gastric bypass (RYGB). The participants were divided according to the time elapsed since surgery and the percentage of excess weight lost (%EWL): 75. The women in the group with %EWL 75 (36.2%) ranged from normal to pre-obese and presented lower late weight gain than the women in the other groups. Weight evolution two or more years after surgery showed the expected reductions, with some individuals responding better to surgery than others. This shows that it is necessary to monitor, investigate and intervene to obtain the desired results.

Associations between the weight trajectories and living location, social cohesion, disorder, and material and social deprivation were estimated after controlling for social and early life factors.FOUR WEIGHT TRAJECTORY GROUPS WERE ESTIMATED: low-increasing (9.7%; low-medium, accelerating (36.2%; medium-high, increasing (43.0%; and high-stable (11.1%. In the low-increasing and medium-high trajectory groups, living in a semi-urban area was inversely related to weight, while living in a rural area was positively related to weight in the high-stable group. Disorder was inversely related to weight in the low-increasing group only. Other important risk factors for high-stable weight included obesity status of the mother, smoking during pregnancy, and overeating behaviors.In this study, associations between local environment factors and weight differed by trajectory group. Early life factors appear to play a more consistent role in weight status. Further work is needed to determine the influence of place on child weight.

    Full Text Available Obesity and its relation to quality of life are multifaceted. The purpose of this paper was to contribute evidence to support a framework for understanding the impact of obesity on quality of life in 42 morbidly obese subjects considering a wide number of potential determinants. A model of weight-related quality of life (WRQL was developed based on the Wilson-Cleary model, considering subjects' weight characteristics, arterial oxygen pressure (PaO2, walking capacity (6-minute walk test, 6MWT, health-related quality of life (HRQL; Physical and Mental Component Summaries of the SF-36 PCS/MCS, and WRQL. The model of WRQL was tested with linear regressions and a path analysis, which showed that as PaO2 at rest increased 6MWT increased. 6MWT was positively associated with the PCS, which in turn was positively related to WRQL along with the MCS. The model showed good fit and explained 38% of the variance in WRQL.

  10. Relationship between different approaches to derive weighting functions related to atmospheric remote sensing problems

    International Nuclear Information System (INIS)

    Rozanov, Vladimir V.; Rozanov, Alexei V.

    2007-01-01

    The paper is devoted to the investigation of the relationship between different methods used to derive weighting functions required to solve numerous inverse problems related to the remote sensing of the Earth's atmosphere by means of scattered solar light observations. The first method commonly referred to as the forward-adjoint approach is based on a joint solution of the forward and adjoint radiative transfer equations and the second one requires the linearized forward radiative transfer equation to be solved. In the framework of the forward-adjoint method we consider two approaches commonly used to derive the weighting functions. These approaches are referenced as the 'response function' and the 'formal solution' techniques, respectively. We demonstrate here that the weighting functions derived employing the formal solution technique can also be obtained substituting the analytical representations for the direct forward and direct adjoint intensities into corresponding expressions obtained in the framework of the response function technique. The advantages and disadvantages of different techniques are discussed

    Tall stature and obesity have been associated with a higher risk of atrial fibrillation (AF), but there have been conflicting reports of the effects of aerobic fitness. We conducted a national cohort study to examine interactions between height or weight and level of aerobic fitness among 1,547,478 Swedish military conscripts during 1969-1997 (97%-98% of all 18-year-old men) in relation to AF identified from nationwide inpatient and outpatient diagnoses through 2012 (maximal age, 62 years). Increased height, weight, and aerobic fitness level (but not muscular strength) at age 18 years were all associated with a higher AF risk in adulthood. Positive additive and multiplicative interactions were found between height or weight and aerobic fitness level (for the highest tertiles of height and aerobic fitness level vs. the lowest, relative excess risk = 0.51, 95% confidence interval (CI): 0.40, 0.62; ratio of hazard ratios = 1.50, 95% CI: 1.34, 1.65). High aerobic fitness levels were associated with higher risk among men who were at least 186 cm (6 feet, 1 inch) tall but were protective among shorter men. Men with the combination of tall stature and high aerobic fitness level had the highest risk (for the highest tertiles vs. the lowest, adjusted hazard ratio = 1.70, 95% CI: 1.61, 1.80). These findings suggest important interactions between body size and aerobic fitness level in relation to AF and may help identify high-risk subgroups.

    Future space missions beyond low Earth orbit will require deconditioned astronauts to perform occupationally relevant tasks within a planetary spacesuit. The prediction of time-to-completion (TTC) of astronaut tasks will be critical for crew safety, autonomous operations, and mission success. This exploratory study determined if the addition of task-specific strength testing to current standard lower body testing would enhance the prediction of TTC in a 1-G test battery. Eight healthy participants completed NASA lower body strength tests, occupationally specific strength tests, and performed six task simulations (hand drilling, construction wrenching, incline walking, collecting weighted samples, and dragging an unresponsive crewmember to safety) in a 48-kg weighted suit. The TTC for each task was recorded and summed to obtain a total TTC for the test battery. Linear regression was used to predict total TTC with two models: 1) NASA lower body strength tests; and 2) NASA lower body strength tests + occupationally specific strength tests. Total TTC of the test battery ranged from 20.2-44.5 min. The lower body strength test alone accounted for 61% of the variability in total TTC. The addition of hand drilling and wrenching strength tests accounted for 99% of the variability in total TTC. Adding occupationally specific strength tests (hand drilling and wrenching) to standard lower body strength tests successfully predicted total TTC in a performance test battery within a weighted suit. Future research should couple these strength tests with higher fidelity task simulations to determine the utility and efficacy of task performance prediction.Taylor A, Kotarsky CJ, Bond CW, Hackney KJ.

    Little is known about the relationship between weight-related behaviors and cognitive load (working memory available to complete mental activities like those required for planning meals, selecting foods, and other health-related decisions). Thus, the purpose of this study was to explore associations between cognitive load and eating behaviors, physical activity, body mass index (BMI), and waist circumference of college students. College students (n=1018) from 13 institutions completed an online survey assessing eating behaviors (e.g., routine and compensatory restraint, emotional eating, and fruit/vegetable intake), stress level, and physical activity level. BMI and waist circumference were measured by trained researchers. A cognitive load score was derived from stress level, time pressure/income needs, race and nationality. High cognitive load participants (n=425) were significantly (Pcognitive loads (n=593). Compared to low cognitive load participants, high cognitive load participants were significantly more likely to eat cognitive load scores had a non-significant trend toward higher BMIs, waist circumferences, and drinking more alcohol than low cognitive load counterparts. In conclusion, cognitive load may be an important contributor to health behaviors. Understanding how cognitive load may affect eating and other weight-related behaviors could potentially lead to improvements in the effectiveness of obesity prevention and intervention programs.

    The impact of activity and inactivity on relative weight and fatness change are best evaluated longitudinally. We examined the longitudinal relationship of physical activity, inactivity, and screen time with relative weight status and percentage body fat (%BF) and explored how it differed by parental overweight status. Non-obese pre-menarcheal girls (173), 8 to 12 years old, were followed until 4 years post-menarche. %BF, BMI z-score, and time spent sleeping, sitting, standing, walking, and in vigorous activity were assessed annually. We developed a physical activity index to reflect time and intensity of activity. Inactivity was defined as the sum of time spent sleeping, sitting, and standing. Screen time was defined as time spent viewing television, videotapes, or playing video games. Parental overweight was defined as at least one parent with BMI>25. In separate linear mixed effects models, activity, inactivity, and screen time were unrelated to BMI z-score longitudinally, with and without accounting for parental overweight. After controlling for parental overweight, activity was inversely related (phistory of overweight represent a target population of high priority for interventions around physical activity and inactivity.

Methods Data were obtained from 926 participants (mean Body Mass Index (BMI (kg/m2 = 35.4; 84% female; mean age = 49.5 years in a placebo-controlled randomized trial for weight loss. At baseline and one-year, participants completed all three HRQOL measures. HRQOL was compared across weight change categories (≥ 5% and 0–4.9% gain, 0–4.9%, 5.0–9.9% and ≥ 10% loss, using effect sizes. Results The weight-related measure of HRQOL exhibited greater improvements with one-year weight loss than either of the generic instruments, with effect sizes ranging from 0.24 to 0.62 for 5–9.9% weight reductions and 0.44 to 0.95 for ≥ 10% reductions. IWQOL-Lite Self-Esteem also showed a small improvement with weight gain. Changes in the two generic measures of HRQOL were inconsistent with each other, and in the case of the SF-36, variable across domains. For participants gaining ≥ 5% of weight, the greatest reductions in HRQOL occurred with respect to SF-36 Mental Health, MCS, and Vitality, with effect sizes of -0.82, -0.70, and -0.63 respectively. Conclusion This study found differences between weight-related and generic measures of health-related quality of life in a one-year weight loss trial, reflecting the potential value of using more than one measure in a trial. Although weight loss was generally associated with improved IWQOL-Lite, physical SF-36 subscale and EQ-5D scores, a small amount of weight gain was associated with a slight improvement on weight-specific HRQOL and almost no change on the EQ-5D, suggesting the

    Although patients with heart failure (HF) have been identified as particularly susceptible to the acute effects of air pollution, the effects of long-term exposure to air pollution on patients with this increasingly prevalent disease are largely unknown. This study was designed to examine the mortality risk associated with residential exposure to traffic-related air pollution among HF patients. A total of 1,389 patients hospitalized with acute HF in greater Worcester, Massachusetts, during 2000 were followed for survival through December 2005. We used daily traffic within 100 and 300 m of residence as well as the distance from residence to major roadways and to bus routes as proxies for residential exposure to traffic-related air pollution. We assessed mortality risks for each exposure variable using Cox proportional hazards models adjusted for prognostic factors. After the 5-year follow-up, only 334 (24%) subjects were still alive. An interquartile range increase in daily traffic within 100 m of home was associated with a mortality hazard ratio (HR) of 1.15 [95% confidence interval (CI), 1.05-1.25], whereas for traffic within 300 m this association was 1.09 (95% CI, 1.01-1.19). The mortality risk decreased with increasing distance to bus routes (HR = 0.88; 95% CI, 0.81-0.96) and was larger for those living within 100 m of a major roadway or 50 m of a bus route (HR = 1.30; 95% CI, 1.13-1.49). Adjustment for area-based income and educational level slightly attenuated these associations. Residential exposure to traffic-related air pollution increases the mortality risk after hospitalization with acute HF. Reducing exposure to traffic-related emissions may improve the long-term prognosis of HF patients.

    Several risk factors for pacemaker (PM) related complications have been reported. However, no study has investigated the impact of lead characteristics on pacemaker-related complications. Patients who received a new pacemaker implant from January 1997 to December 2011 were selected from the Taiwan National Health Insurance Database. This population was grouped according to the pacemaker lead characteristics in terms of fixation and insulation. The impact of the characteristics of leads on early heart perforation was analyzed by multivariable logistic regression analysis, while the impact of the lead characteristics on early and late infection and late heart perforation over a three-year period were analyzed using Cox regression. This study included 36,104 patients with a mean age of 73.4±12.5 years. In terms of both early and late heart perforations, there were no significant differences between groups across the different types of fixation and insulations. In the multivariable Cox regression analysis, the pacemaker-related infection rate was significantly lower in the active fixation only group compared to either the both fixation (OR, 0.23; 95% CI, 0.07-0.80; P = 0.020) or the passive fixation group (OR, 0.26; 95% CI, 0.08-0.83; P = 0.023). There was no difference in heart perforation between active and passive fixation leads. Active fixation leads were associated with reduced risk of pacemaker-related infection.

    Objective To examine the relationship between job type, weight status and lifestyle factors that are potential contributors to obesity including, diet, physical activity and perceived stress among employees enrolled in the Working on Wellness (WOW) project. Methods Randomly selected employees at 24 worksites completed a baseline survey (n=1700); some also an in-person survey and anthropometric measures (n=1568). Employees were classified by US Labor standards as: white collar (n=1297), blue collar (n=303), or service worker (n=92), 8 unknown. Associations were analyzed using Chi-Square, GLM procedures, and adjusted for demographics using Logistic Regression. Results In unadjusted models, BMI of service workers was higher than white collar workers; F&V intake was higher for service and blue collar than white collar; white collar workers reported highest stress levels in job and life. However, in models adjusted for demographics, the only significant difference was to physical activity (i.e., MET/min per week), with blue collar workers reporting higher levels of physical activity than service workers, who reported higher levels than the white collar workers. Conclusions Future research should further examine the relationship between health and job status to corroborate the results of the current study and to consider designing future worksite health promotion interventions that are tailored by job category.

    Aim: Aim of this study was to show whether or not acquisition-weighted chemical shift imaging (AW-CSI) allows the determination of PCr and ATP in the lateral and posterior wall of the human heart at 1.5 T. Methods: 12 healthy volunteers were examined using a conventional chemical shift imaging (CSI) and an AW-CSI. The sequences differed only in the number of repetitions for each point in k space. A hanning function was used as filter function leading to 7 repetitions in the center of the k space and 0 in the corners. Thus, AW-CSI had the same resolution as the CSI sequence. The results for both sequences were analyzed using identically positioned voxels in the septal, anterior, lateral and posterior wall. Results: The determined averaged AW-CSI signal to noise ratios were higher for PCr by a factor of 1.3 and for ATP by 1.4 than those of CSI. The PCr/ATP ratios were higher by a factor of 1.2 - 1.3 and showed a smaller standard deviation in all locations for AW-CSI. The mean PCr/ATP ratios determined by AW-CSI of septal, lateral and posterior wall were almost identical (1.72 - 1.76), while it was higher in the anterior wall (1.9). Conclusions: The reduced contamination in AW-CSI improves the signal to noise ratio and the determination of the PCr/ATP ratio in cardiac 31 P spectroscopy compared to CSI with the same resolution. The results in volunteers indicate that AW-CSI renders 31 P spectroscopy of the lateral and posterior wall of the human heart feasible for patient studies at 1.5 T. (orig.) [de

  4. Neural correlates to food-related behavior in normal-weight and overweight/obese participants.

    Full Text Available Two thirds of US adults are either obese or overweight and this rate is rising. Although the etiology of obesity is not yet fully understood, neuroimaging studies have demonstrated that the central nervous system has a principal role in regulating eating behavior. In this study, functional magnetic resonance imaging and survey data were evaluated for correlations between food-related problem behaviors and the neural regions underlying responses to visual food cues before and after eating in normal-weight individuals and overweight/obese individuals. In normal-weight individuals, activity in the left amygdala in response to high-calorie food vs. nonfood object cues was positively correlated with impaired satiety scores during fasting, suggesting that those with impaired satiety scores may have an abnormal anticipatory reward response. In overweight/obese individuals, activity in the dorsolateral prefrontal cortex (DLPFC in response to low-calorie food cues was negatively correlated with impaired satiety during fasting, suggesting that individuals scoring lower in satiety impairment were more likely to activate the DLPFC inhibitory system. After eating, activity in both the putamen and the amygdala was positively correlated with impaired satiety scores among obese/overweight participants. While these individuals may volitionally suggest they are full, their functional response to food cues suggests food continues to be salient. These findings suggest brain regions involved in the evaluation of visual food cues may be mediated by satiety-related problems, dependent on calorie content, state of satiation, and body mass index.

    Intrinsic fluctuations of a protein enable it to sample a large repertoire of conformers including the open and closed forms. These distinct forms of the protein called conformational substates pre-exist together in equilibrium as an ensemble independent from its ligands. The role of ligand might be simply to alter the equilibrium toward the most appropriate form for binding. Normal mode analysis is proved to be useful in identifying the directions of conformational changes between substates. In this study, we demonstrate that the ratios of normalized weights of a few normal modes driving the protein between its substates can give insights about the ratios of kinetic conversion rates of the substates, although a direct relation between the eigenvalues and kinetic conversion rates or populations of each substate could not be observed. The correlation between the normalized mode weight ratios and the kinetic rate ratios is around 83% on a set of 11 non-enzyme proteins and around 59% on a set of 17 enzymes. The results are suggestive that mode motions carry intrinsic relations with thermodynamics and kinetics of the proteins.

    Heart rate variability (HRV) is a marker of sympathovagal balance; it has been implicated in erectile function and is also altered by tobacco use. Furthermore, smoking and erectile health are strongly related, given that smokers are at increased risk for erectile dysfunction. Few studies have explored the interrelationships between smoking, HRV, and erectile function concurrently. The aim of this study was to examine potential mechanisms underlying tobacco's effects on penile hemodynamics by exploring the mediating role of HRV. The sample comprised 119 men (smokers = 64; nonsmokers = 55) (mean age 28.90 years; standard deviation (SD) 11.68; range 18-58) selected from the control conditions of three previously published experiments. Participants were free from a history of cardiovascular disease, myocardial infarct, and/or cardiac/cardiovascular medication use. During a laboratory visit, self-report, anthropometric, cardiovascular, and electrocardiographic data were assessed, as well as sexual arousal responses elicited from viewing an erotic film. Objective sexual arousal indices (circumferential change via penile plethysmography), self-reported erectile function (per the erectile function domain score of the International Index of Erectile Function [IIEF-EF]), and time- (SD of beat-to-beat intervals) and frequency-domain parameters of HRV (ratio of low-frequency [LF] power to high-frequency [HF] power [LF/HF ratio]) were assessed. Being a current long-term cigarette smoker was associated with dysregulated sympathovagal balance (higher LF/HF ratios, indicative of sympathetic nervous system dominance), which in turn showed inverse relations with magnitude of erectile tumescence. HRV did not mediate relations between tobacco use and either IIEF-EF scores or resting penile circumference. Findings suggest that dysfunctional cardiac autonomic tone may be an underlying mechanism by which tobacco exerts its deleterious effects on erectile health. Further research

    Clinical data indicating a heart rate (HR) target during rate control therapy for permanent atrial fibrillation (AF) and assessing its eventual relationship with reduced exercise tolerance are lacking. The present study aims at investigating the impact of resting HR on the hemodynamic response to exercise in permanent AF patients by means of a computational cardiovascular model. The AF lumped-parameter model was run to simulate resting (1 Metabolic Equivalent of Task-MET) and various exercise conditions (4 METs: brisk walking; 6 METs: skiing; 8 METs: running), considering different resting HR (70 bpm for the slower resting HR-SHR-simulations, and 100 bpm for the higher resting HR-HHR-simulations). To compare relative variations of cardiovascular variables upon exertion, the variation comparative index (VCI)-the absolute variation between the exercise and the resting values in SHR simulations referred to the absolute variation in HHR simulations-was calculated at each exercise grade (VCI4, VCI6 and VCI8). Pulmonary venous pressure underwent a greater increase in HHR compared to SHR simulations (VCI4 = 0.71, VCI6 = 0.73 and VCI8 = 0.77), while for systemic arterial pressure the opposite is true (VCI4 = 1.15, VCI6 = 1.36, VCI8 = 1.56). The computational findings suggest that a slower, with respect to a higher resting HR, might be preferable in permanent AF patients, since during exercise pulmonary venous pressure undergoes a slighter increase and systemic blood pressure reveals a more appropriate increase.

    To determine the impact of preoperative serum creatinine level in non-dialyzable patients on postoperative morbidity and mortality. This is a prospective study, where serum creatinine was used to give primary assessment on renal function status preoperatively. This study includes 1,033 patients, who underwent coronary artery bypass grafting, or valve(s) operations. The study took place at Al-Hada Military Hospital, Taif, Kingdom of Saudi between May 2008 and January 2012. Data were statistically analyzed using Chi square (x2) test and multivariable logistic regression, to evaluate the postoperative morbidity and mortality risks associated with low serum creatinine levels. Postoperative mortality increased with high serum creatinine level >1.8 mg/dL (pcreatinine level of more than 1.8 mg/dL was associated with increased risk of re-operation for bleeding, postoperative renal failure, prolonged ventilatory support, ICU stay, and total hospital stay. Perioperative serum creatinine is strongly related to post operative morbidity and mortality in open heart surgery. High serum creatinine in non-dialyzable patients can predict the increased morbidity and mortality after cardiac operations.

    Central venous catheters are widely used in critically ill patients; however, they are also associated with increased morbidity and mortality. The literature may underestimate the incidence of catheter-inducible right atrial thrombi that are asymptomatic but potentially life threatening. The recognized risk factors for its development include infections related to the catheter, endothelial injury secondary to mechanical and chemical damage induced by certain medications and infused fluids. The characteristics of the patient and the catheter, such as size, material, type, location and ease of insertion, as well as the duration of placement play an additional role. We report the case of a 38-year-old man, who developed an asymptomatic catheter-inducible right atrial thrombi requiring open heart surgery, after taking a central venous catheter for thirty-five days. The present case highlights existing limitations in making a correct and fast diagnosis, which should be anticipated in patients with multiple risk factors for thrombosis. Given the limited recommendations available, we consider that the most appropriate strategy should be individualized.

    A negative body image has been associated with a variety of negative health and well-being outcomes. Social pressures from others, in the form of weight-related social control, may serve to exacerbate this effect, especially for college-aged women. Undergraduate students (N=399) completed a variety of questionnaires assessing weight-related social control, well-being, and diet and exercise behaviors. The results suggest that weight is associated with a variety of negative health and well-being outcomes and particularly for women, weight-related social control is also associated with these negative effects. In addition, men of higher body mass indexes (BMIs) or higher self-perceived weight did not experience negative health and well-being outcomes to the same degree that overweight women did. Parents in particular seem to instigate weight-related social control to change students' diet and exercise behaviors. These results help clarify the effects of weight-related social control in a college population, where weight may be especially important. Copyright © 2013 Elsevier Ltd. All rights reserved.

    Full Text Available Abstract Background Folic acid taken in early pregnancy reduces risks for delivering offspring with several congenital anomalies. The mechanism by which folic acid reduces risk is unknown. Investigations into genetic variation that influences transport and metabolism of folate will help fill this data gap. We focused on 118 SNPs involved in folate transport and metabolism. Methods Using data from a California population-based registry, we investigated whether risks of spina bifida or conotruncal heart defects were influenced by 118 single nucleotide polymorphisms (SNPs associated with the complex folate pathway. This case-control study included 259 infants with spina bifida and a random sample of 359 nonmalformed control infants born during 1983–86 or 1994–95. It also included 214 infants with conotruncal heart defects born during 1983–86. Infant genotyping was performed blinded to case or control status using a designed SNPlex assay. We examined single SNP effects for each of the 118 SNPs, as well as haplotypes, for each of the two outcomes. Results Few odds ratios (ORs revealed sizable departures from 1.0. With respect to spina bifida, we observed ORs with 95% confidence intervals that did not include 1.0 for the following SNPs (heterozygous or homozygous relative to the reference genotype: BHMT (rs3733890 OR = 1.8 (1.1–3.1, CBS (rs2851391 OR = 2.0 (1.2–3.1; CBS (rs234713 OR = 2.9 (1.3–6.7; MTHFD1 (rs2236224 OR = 1.7 (1.1–2.7; MTHFD1 (hcv11462908 OR = 0.2 (0–0.9; MTHFD2 (rs702465 OR = 0.6 (0.4–0.9; MTHFD2 (rs7571842 OR = 0.6 (0.4–0.9; MTHFR (rs1801133 OR = 2.0 (1.2–3.1; MTRR (rs162036 OR = 3.0 (1.5–5.9; MTRR (rs10380 OR = 3.4 (1.6–7.1; MTRR (rs1801394 OR = 0.7 (0.5–0.9; MTRR (rs9332 OR = 2.7 (1.3–5.3; TYMS (rs2847149 OR = 2.2 (1.4–3.5; TYMS (rs1001761 OR = 2.4 (1.5–3.8; and TYMS (rs502396 OR = 2.1 (1.3–3.3.

    In the popular news media, public health officials routinely emphasize the health risks of obesity and portray weight as under personal control. These messages may increase support for policies designed to reduce rates of obesity, but can also increase antifat stigma. Less often, the media cover 'Health at Every Size' or 'Fat Rights' perspectives that may have the opposite effects. We investigated how exposure to different 'fat frames' shifts attitudes about weight and support for obesity policies. Across four experiments (n=2187), people read constructed news articles framing fatness as negative (unhealthy, controllable, acceptable to stigmatize) or positive (healthy, uncontrollable, unacceptable to stigmatize). Compared with people who read fat-positive frames, people who read fat-negative frames expressed more: belief in the health risks of being fat (d=0.95-1.22), belief weight is controllable (d=0.38-0.55), support for charging obese people more for health insurance (d=0.26-0.77), antifat prejudice (in three out of four experiments, d=0.28-0.39), willingness to discriminate against fat people (d=0.39-0.71) and less willingness to celebrate body size diversity (d=0.37-0.64). They were also less willing to say that women at the lower end of the obese range could be healthy at their weights. Effects on support for public policies, however, were generally small and/or nonsignificant. Compared with a control condition, exposure to fat-positive frames generally shifted attitudes more than fat-negative frames. In experiment 4, adding a message about the unacceptability of weight-based discrimination to unhealthy/controllable news articles only reduced antifat stigma on one of three measures compared with articles adding a discrimination-acceptable message. Exposure to different news frames of fat can shift beliefs about weight-related health risks and weight-based stigma. Shifting policy attitudes, however, is more challenging.

  16. Age Weights for Health Services Derived from the Relative Social Willingness-to-Pay Instrument.

    2017-04-01

    The effect of a patient's age on the social valuation of health services remains controversial, with empirical results varying in magnitude and implying a different age-value profile. This article employs a new methodology to re-examine these questions. Data were obtained from 2 independent Web-based surveys that administered the Relative Social Willingness to Pay instrument. In the first survey, the age of the patient receiving a life-saving service was varied. Patients were left with either poor mental or physical health. In the second survey, patient age was varied for a service that fully cured the patient's poor mental or physical health. In total, therefore, 4 sets of age weights were obtained: weights for life-extending services with poor physical or mental health outcomes and weights for quality-of-life improvement for patients in poor mental or physical health. Results were consistent. Increasing age was associated in each case with a monotonic decrease in the social valuation of the services. The decrease in value was quantitatively small until age 60 years. By age 80 years, the social value of services had declined by about 50%. The decline commenced at an earlier age in the context of physical health, although the magnitude of the decrement by age 80 years was unrelated to the type of service. With 1 exception, there was little difference in the valuation of services by the age of the survey respondent. Respondents aged >60 years placed a lower, not higher, value on quality-of-life improvement for elderly individuals than other respondents. There was no difference in the valuation of life-extending services.

    The National Heart, Lung, and Blood Institute (NHLBI) AIDS Program's goal is to provide direction and support for research and training programs in areas of HIV-related heart, lung, blood, and sleep (HLBS) diseases. To better define NHLBI current HIV-related scientific priorities and with the goal of identifying new scientific priorities and gaps in HIV-related HLBS research, a wide group of investigators gathered for a scientific NHLBI HIV Working Group on December 14-15, 2015, in Bethesda, MD. The core objectives of the Working Group included discussions on: (1) HIV-related HLBS comorbidities in the antiretroviral era; (2) HIV cure; (3) HIV prevention; and (4) mechanisms to implement new scientific discoveries in an efficient and timely manner so as to have the most impact on people living with HIV. The 2015 Working Group represented an opportunity for the NHLBI to obtain expert advice on HIV/AIDS scientific priorities and approaches over the next decade.

    The purpose of this study was to describe the workplace environments of young adults and examine associations with diet, physical activity (PA) and body mass index (BMI). Cross-sectional data were collected (2008-2009) from 1538 employed young adult participants in Project EAT (Eating and Activity among Teens and Young Adults), a diverse population-based sample. Survey measures assessed height, weight, diet, moderate-to-vigorous PA, transportation-related PA and perceptions of the workplace food and PA environments (eg, soda availability, coworker support). Healthful characteristics were summed to reflect overall workplace healthfulness. Modified Poisson regression analyses conducted in 2015 identified associations between workplace food and PA environments and diet, PA and BMI. The healthfulness of workplace environments was suboptimal. Greater exposure to healthful workplace characteristics was related to more young adults engaged in favourable diet and PA behaviours and a lower prevalence obesity. For example, adjusted rates of obesity were 24% and 17% among those reporting low (≤1 characteristic) versus high (≥3 characteristics) exposure to healthful food environments, respectively (pwork and perceived ease of eating a healthy diet or being active at work. A more healthful workplace environment overall, including physical attributes and perceived social norms, may contribute to more favourable weight-related behaviours and lower prevalence of obesity among young adults. Employer-initiated and community-initiated policies may represent one way to create healthier workplace environments for young adults. Published by the BMJ Publishing Group Limited.

    The aim of this study was to examine sexual inactivity and occurrence of selected sexually transmitted infections in relation to body mass index. We used data from two large Danish population-based cross-sectional studies conducted in 1991-1995 (HPV study: 6869 women, aged 22-32 years) and in 2004......-2005 (Liva study: 19,484 women, aged 18-45 years). Data were collected using a structured interview and measured weight, height, high-risk human papillomavirus DNA, Chlamydia DNA for the HPV study and a structured questionnaire for the Liva study. Overweight and obese women were more likely to have had...... no lifetime sexual partner or no sexual partner in the last year, e.g., obese women had a threefold (95 percent CI: 1.95-5.04) odds ratio of having had no sexual partner in the last year compared to normal weight women. Additionally, overweight and obese women had a lower likelihood of genital warts and high...

  1. Centroid Localization of Uncooperative Nodes in Wireless Networks Using a Relative Span Weighting Method

    Directory of Open Access Journals (Sweden)

    2010-01-01

    Full Text Available Increasingly ubiquitous wireless technologies require novel localization techniques to pinpoint the position of an uncooperative node, whether the target is a malicious device engaging in a security exploit or a low-battery handset in the middle of a critical emergency. Such scenarios necessitate that a radio signal source be localized by other network nodes efficiently, using minimal information. We propose two new algorithms for estimating the position of an uncooperative transmitter, based on the received signal strength (RSS of a single target message at a set of receivers whose coordinates are known. As an extension to the concept of centroid localization, our mechanisms weigh each receiver's coordinates based on the message's relative RSS at that receiver, with respect to the span of RSS values over all receivers. The weights may decrease from the highest RSS receiver either linearly or exponentially. Our simulation results demonstrate that for all but the most sparsely populated wireless networks, our exponentially weighted mechanism localizes a target node within the regulations stipulated for emergency services location accuracy.

    The objective of this cohort study was to explore relationships among the home food environment (HFE), child/parent characteristics, diet quality, and measured weight status among 699 child-parent pairs from King County, WA, and San Diego County, CA. HFE variables included parenting style/feeding practices, food rules, frequency of eating out, home food availability, and parents' perceptions of food costs. Child dietary intake was measured by 3-day recall and diet quality indicators included fruits and vegetables, sweet/savory snacks, high-calorie beverages, and Dietary Approaches to Stop Hypertension (DASH) score. Individual linear regression models were run in which child BMI z score and child diet quality indicators were dependent variables and HFE variables and child/parent characteristics were independent variables of interest. Fruit and vegetable consumption was associated with parental encouragement/modeling (β=.68, Ppermissive feeding style (-1.04, Ppermissive feeding style (0.14, Pparent's use of food restriction (0.21, Ppermissive feeding style (0.16, Pparenting around eating and food availability are related to child diet quality and weight status.

    The media has the ability to affect public opinion and policy direction. Prevalence of morbid obesity in Canada is increasing; as is the only effective long-term treatment, weight loss surgery (WLS). Limited research has explored media re/presentations of WLS. The purpose of this study was to examine national online news coverage (and reader comments) of WLS using content analysis. We sought to understand the dominant messages being conveyed within the news texts and reader comments, specifically whose voice was represented, who was the intended audience and what was the overall tone. Articles and comments were retrieved from the Canadian Broadcasting Corporation news web site and analysed using line-by-line techniques. Articles were predominantly 'positive/supportive' (63%) in tone and frequently presented the voices and opinions of 'experts' conveying a biomedical perspective. Comments were overwhelmingly 'negative' (56%) and often derogatory including such language as 'piggy' and 'fatty'. Comments were almost exclusively anonymous (99%) and were frequently directed at other commenters (33%) and 'fat' people (6%). The potentially problematic nature of media framing and reader comments, particularly as they could relate to weight-based stigmatization and discrimination is discussed. © 2012 The Authors.

    Paternal characteristics have never been considered in the relation between maternal schizophrenia and adverse pregnancy outcomes. The aim of our study was to consider different paternal ages while investigating the relation between maternal schizophrenia and low birth weight (LBW), using a nationwide population-based dataset. Our study used data from the 2001 to 2003 Taiwan National Health Insurance Research Dataset and birth certificate registry. A total of 543 394 singleton live births were included. We performed multivariate logistic regression analyses to explore the relation between maternal schizophrenia and the risk of LBW, taking different paternal age groups into account (aged 29 years or younger, 30 to 39 years, and 40 years and older), and after adjusting for other characteristics of infant, mother, and father as well as the difference between the parent's ages. Mothers with schizophrenia had a higher percentage of LBW infants than mothers who did not (11.8%, compared with 6.8%). For infants whose mothers had schizophrenia, the adjusted odds ratios of LBW were 1.47 (95% CI 1.02 to 2.27, P paternal age groups of 30 to 39 years and 40 years or older, respectively. However, maternal schizophrenia was not a significant predictor of LBW for infants whose fathers were aged 29 years and younger. The relation between LBW and maternal schizophrenia is modified by paternal age. More attention should be paid to the interaction of paternal characteristics and maternal psychiatric disorders in producing adverse pregnancy outcomes.

    Iodine-123-metaiodobenzylguanidine ( 123 I-MIBG) has been used to assess the integrity and function of the cardiac sympathetic nervous system in patients with heart failure. Heart-type fatty acid binding protein (H-FABP) is released into the circulation when the myocardium is injured, and H-FABP has been recently used as a novel marker for the diagnosis of ongoing myocardial damage. The aim of the present study was to compare cardiac sympathetic nervous activity assessed by 123 I-MIBG imaging with serum levels of H-FABP in patients with heart failure. Fifty patients with chronic heart failure were studied. 123 I-MIBG imaging was carried out at 30 min (early) and 240 min (delayed) after the tracer injection. We measured serum levels of H-FABP using a sandwich enzyme linked immunosorbent assay. Heart to mediastinum (H/M) ratios of 123 I-MIBG decreased and washout rate increased with higher New York Heart Association (NYHA) functional class. H-FABP, norepinephrine and brain natriuretic peptide (BNP) levels increased as the severity of NYHA class advanced. Delayed H/M ratio was significantly correlated with H-FABP (r=-0.296, p=0.029) and BNP (r=-0.335, p=0.0213). Myocardial washout rate of 123 I-MIBG was also correlated with H-FABP (r=0.469, p 123 I-MIBG imaging is an appropriate approach to evaluate non-invasively not only cardiac sympathetic nervous activity, but also latent ongoing myocardial damage in the failing heart.

    We reviewed scientific literature regarding the effectiveness of social media-based interventions about weight-related behaviors and body weight status. A keyword search were performed in May 2017 in the Clinical-Trials.gov, Cochrane Library, PsycINFO, PubMed, and Web of Science databases. We conducted a meta-analysis to estimate the pooled effect size of social media-based interventions on weight-related outcome measures. We identified 22 interventions from the keyword and reference search, including 12 randomized controlled trials, 6 pre-post studies and 3 cohort studies conducted in 9 countries during 2010-2016. The majority (N = 17) used Facebook, followed by Twitter (N = 4) and Instagram (N = 1). Intervention durations averaged 17.8 weeks with a mean sample size of 69. The meta-analysis showed that social media-based interventions were associated with a statistically significant, but clinically modest reduction of body weight by 1.01 kg, body mass index by 0.92 kg/m2, and waist circumstance by 2.65 cm, and an increase of daily number of steps taken by 1530. In the meta-regression there was no doseresponse effect with respect to intervention duration. The boom of social media provides an unprecedented opportunity to implement health promotion programs. Future interventions should make efforts to improve intervention scalability and effectiveness.

    To analyze weight gain, metabolic hormones, and homocysteine (Hcys) levels in children and adolescents on antipsychotics (AP) during a year-long follow-up. 117 patients, AP-naïve or quasi-naïve (less than 30 days on AP), were included. Weight, body mass index (BMI), BMI z-score (z-BMI), and levels of leptin, insulin, insulin resistance (HOMA-IR), adiponectin, ghrelin, thyroid stimulating hormone (TSH), free thyroxine (FT4), and Hcys were measured at baseline, and at 3, 6, and 12 months, while patients remained on the same AP. Patients (mean age: 14.4 ± 3 years; 64.1 % male) were on risperidone (N = 84), olanzapine (N = 20) or quetiapine (N = 13) from baseline up to 1-year follow-up and significantly increased weight (5.8 ± 4.3 kg at 3-month, 8.1 ± 6.1 kg at 6-month, and 11.6 ± 7.0 kg at 1 year), BMI, and z-BMI. Leptin levels significantly increased from baseline to 3 and 6 months, as did TSH levels from baseline to 3 months, while FT4 levels decreased from baseline to 3 and 6 months. Patients with BMI >85th percentile at baseline (N = 16) significantly increased weight, BMI, and z-BMI, more than patients with normal BMI over time. Higher baseline levels of insulin, HOMA-IR, and leptin were associated with increased weight/BMI during follow-up, while higher baseline levels of FT4, adiponectin, and ghrelin were associated with lower weight/BMI during follow-up. All AP were associated with increased weight and BMI/z-BMI in all of the assessments; however, at 1-year assessment, this increase was significantly higher for patients on quetiapine. Both higher baseline levels of insulin, HOMA-IR, and leptin, as well as being overweight/obese at baseline were associated with increased weight/BMI during 1-year follow-up in children and adolescents on AP. Awareness of weight-related parameters in this population may help inform decisions regarding AP prescriptions.

    This study aimed to assess the prevalence of overweight misperception, unhealthy diet practices, and factors associated with these weight-related behaviors among Korean adolescents. The subjects were a nationally representative sample of non-overweight students (52,515 in 2005, 64,084 in 2006, and 67,113 in 2007) in middle and high schools who completed the Korea Youth Risk Behavior Web-Based Survey. The prevalence of weight-related behaviors and factors associated with these behaviors were assessed using a complex sampling design. Of non-overweight students, 14.9% of boys and 22.2% of girls reported their weight as overweight/obese. Dieting within the last year was reported by 19.8% of boys and 41.8% of girls. Of those who attempted dieting, 17.1% of boys and 24.6% of girls indicated practicing at least one unhealthy diet behavior within the last month. Overweight misperceptions were independently associated with diet attempts and unhealthy diets after adjustment for weight status, and demographic, social, and psychological factors. Additionally, these weight-related behaviors were also associated with psychosocial factors such as low school achievement, sadness, suicidal ideation, increased stress perception, and cigarette or alcohol use. In conclusion, the high prevalence of inappropriate weight-related behaviors suggests a need for comprehensive approaches to improve weight-related behaviors in non-overweight Korean adolescents.

    2002-01-01

    Full Text Available OBJECTIVE: To assess the association between cardiovascular risk factors and acute myocardial infarction as the first manifestation of ischemic heart disease, correlating them with coronary angiographic findings. METHODS: We carried out a cross-sectional study of 104 patients with previous acute myocardial infarction, who were divided into 2 groups according to the presence or absence of angina prior to acute myocardial infarction. We assessed the presence of angina preceding acute myocardial infarction and risk factors, such as age >55 years, male sex, smoking, systemic arterial hypertension, lipid profile, diabetes mellitus, obesity, sedentary lifestyle, and familial history of ischemic heart disease. On coronary angiography, the severity of coronary heart disease and presence of left ventricular hypertrophy were assessed. RESULTS: Of the 104 patients studied, 72.1% were males, 90.4% were white, 73.1% were older than 55 years, and 53.8% were hypertensive. Acute myocardial infarction was the first manifestation of ischemic heart disease in 49% of the patients. The associated risk factors were systemic arterial hypertension (RR=0.19; 95% CI=0.06-0.59; P=0.04 and left ventricular hypertrophy (RR=0.27; 95% CI=0,.8-0.88; P=0.03. The remaining risk factors were not statistically significant. CONCLUSION: Prevalence of acute myocardial infarction as the first manifestation of ischemic heart disease is high, approximately 50%. Hypertensive individuals more frequently have symptoms preceding acute myocardial infarction, probably due to ventricular hypertrophy associated with high blood pressure levels.

    2014-01-01

    Background Atmospheric pollution is a major public health concern. It can affect placental function and restricts fetal growth. However, scientific knowledge remains too limited to make inferences regarding causal associations between maternal exposure to air pollution and adverse effects on pregnancy. This study evaluated the association between low birth weight (LBW) and maternal exposure during pregnancy to traffic related air pollutants (TRAP) in São Paulo, Brazil. Methods and findings Analysis included 5,772 cases of term-LBW (<2,500 g) and 5,814 controls matched by sex and month of birth selected from the birth registration system. Mothers’ addresses were geocoded to estimate exposure according to 3 indicators: distance from home to heavy traffic roads, distance-weighted traffic density (DWTD) and levels of particulate matter ≤10 µg/m3 estimated through land use regression (LUR-PM10). Final models were evaluated using multiple logistic regression adjusting for birth, maternal and pregnancy characteristics. We found decreased odds in the risk of LBW associated with DWTD and LUR-PM10 in the highest quartiles of exposure with a significant linear trend of decrease in risk. The analysis with distance from heavy traffic roads was less consistent. It was also observed that mothers with higher education and neighborhood-level income were potentially more exposed to TRAP. Conclusions This study found an unexpected decreased risk of LBW associated with traffic related air pollution. Mothers with advantaged socioeconomic position (SEP) although residing in areas of higher vehicular traffic might not in fact be more expose to air pollution. It can also be that the protection against LBW arising from a better SEP is stronger than the effect of exposure to air pollution, and this exposure may not be sufficient to increase the risk of LBW for these mothers.

    2010-11-01

    To assess the relationship between number of meals eaten and weight status, and to assess potential confounders of this relationship. A total of 2870 (participation rate: 85%) 9th and 10th graders (mean age: 15.5 years) at 33 schools completed questionnaires in May 2005. Number of meals was measured with questions asking whether they ate breakfast, lunch, dinner, and supper the day before, giving a scale ranging from zero to four meals/day. Data on gender, height, weight, education plans, intake of fruits and vegetables, consumption of unhealthy snacks, TV/computer time, physical activity level, and dieting were also collected. The proportions of overweight adolescents related to the number of meals eaten were: 10% (0-1 meals, n = 107), 18% (2 meals, n = 399), 14% (3 meals, n = 925), and 10% (4 meals, n = 1402), p ≤ 0.001. Low education plans, high TV/computer time, low physical activity level, and dieting were all positively associated with both being overweight and not having four meals. Being a boy was positively associated with being overweight but negatively associated with not having four meals. High intake of unhealthy snacks was negatively associated with being overweight, but positively associated with not having four meals. In a logistic regression analysis, adjusting for all variables mentioned, odds ratio for being overweight were 0.8 (95% CI 0.3-1.9), 1.8 (95% CI 1.2-2.7) and 1.6 (95% CI 1.2-2.3), respectively, for eating one or zero, two, and three meals compared to four meals. Eating four meals/day was significantly negatively related to being overweight, also when controlling for potential confounding factors.

  16. Melanocortin-3 receptors in the limbic system mediate feeding-related motivational responses during weight loss

    2016-07-01

    Full Text Available Objective: Appetitive responses to weight loss are mediated by a nutrient-sensing neural network comprised of melanocortin neurons. The role of neural melanocortin-3 receptors (MC3R in mediating these responses is enigmatic. Mc3r knockout mice exhibit a paradoxical phenotype of obesity and reduced feeding-related behaviors in situations of nutrient scarcity. Here we examined whether MC3Rs expressed in mesolimbic neurons regulate feeding-related motivational responses. Methods: Interactions between Mc3r genotype, cognitive function and energy balance on food self-administration were assessed using operant conditioning with fixed- and progressive ratio (FR1/PR1 settings. Inhibition of Mc3r transcription by a loxP-flanked transcriptional blocker (TB in C57BL/6JN mice (Mc3rTB/TB was reversed in mesolimbic neurons using DAT-Cre (DAT-MC3R. Results: Caloric restriction (CR caused 10–15% weight loss and increased motivation to acquire food rewards during training sessions. c-Fos-expression in the nucleus accumbens was increased 1 h following food presentation. While exhibiting weight loss, total food self-administration, enhanced motivation to self-administer food rewards in training sessions held during CR and c-Fos-activation in the nucleus accumbens following re-feeding were all markedly attenuated in Mc3rTB/TB mice. In contrast, cognitive abilities were normal in Mc3rTB/TB mice. Total food self-administration during FR1 sessions was not rescued in DAT-MC3R mice, however enhanced motivational responses to self-administer food rewards in PR1 conditions were restored. The nutrient-partitioning phenotype observed with Mc3r-deficiency was not rescued in DAT-MC3R mice. Conclusions: Mesolimbic MC3Rs mediate enhanced motivational responses during CR. However, they are insufficient to restore normal caloric loading when food is presented during CR and do not affect metabolic conditions altering nutrient partitioning.

    Full Text Available Clinical data indicating a heart rate (HR target during rate control therapy for permanent atrial fibrillation (AF and assessing its eventual relationship with reduced exercise tolerance are lacking. The present study aims at investigating the impact of resting HR on the hemodynamic response to exercise in permanent AF patients by means of a computational cardiovascular model.The AF lumped-parameter model was run to simulate resting (1 Metabolic Equivalent of Task-MET and various exercise conditions (4 METs: brisk walking; 6 METs: skiing; 8 METs: running, considering different resting HR (70 bpm for the slower resting HR-SHR-simulations, and 100 bpm for the higher resting HR-HHR-simulations. To compare relative variations of cardiovascular variables upon exertion, the variation comparative index (VCI-the absolute variation between the exercise and the resting values in SHR simulations referred to the absolute variation in HHR simulations-was calculated at each exercise grade (VCI4, VCI6 and VCI8.Pulmonary venous pressure underwent a greater increase in HHR compared to SHR simulations (VCI4 = 0.71, VCI6 = 0.73 and VCI8 = 0.77, while for systemic arterial pressure the opposite is true (VCI4 = 1.15, VCI6 = 1.36, VCI8 = 1.56.The computational findings suggest that a slower, with respect to a higher resting HR, might be preferable in permanent AF patients, since during exercise pulmonary venous pressure undergoes a slighter increase and systemic blood pressure reveals a more appropriate increase.

    Individuals who are overweight or obese report body image concerns and lower self-esteem. However, little is known about the mechanisms underpinning these associations. The objective of this study was to test body-related shame and guilt as mediators in the association between weight status and self-esteem. Young adult participants (n = 790) completed assessments of self-esteem and body-related guilt and shame, and weight status indicators were measured by trained technicians. Findings from multiple mediation analyses suggest that body-related shame mediates the relationship between weight status and self-esteem. If replicated in longitudinal studies, these findings suggest that reducing body-related emotions may have important implications for improving self-esteem in clinical weight management. © The Author(s) 2015.

    2017-01-01

    We present here the first evidence of correlation between canine anxiety-related behavioural problems and heart rate variability (HRV). HRV is known to be related to a range of mental disorders in humans; however this has not been explored in dogs. Behavioural problems in dogs can result in suffering, property destruction and human injury. Dog behaviour problems were assessed by owner questionnaire and the extreme high and low scoring dogs were recruited into either affected (n=10) or unaffected (n=20) groups. HRV was assessed in dogs at their homes, while being held in lateral recumbency for 5min using manual restraint. Salivary cortisol samples were taken before and after HRV testing. Dogs were assessed as either being reactive to the procedure (barking, growling, struggling or shaking) or unreactive. There was no effect of reactivity or behaviour problems on salivary cortisol levels at baseline or in response to the treatment. There was a significant effect of reactivity on HR (F 1,26 =5.54; P=0.026), and no effect of behaviour problems (F 1,26 =1.07; P=0.311). There was no effect of reactivity on any of the HRV measures. The presence of behaviour problems had a significant effect on a range of measures of HRV, with unaffected dogs having higher standard deviation of RR intervals (F 1,26 =6.39; P=0.018), higher high frequency spectrum (F 1,26 =5.23; P=0.031) and higher low frequency spectrum (F 1,26 =9.25; P=0.005) power. There was no effect of behaviour problems on very low frequency spectrum power (F 1,26 =1.40; P=0.248). Together these results provide evidence for a fundamental physiological difference between dogs affected or unaffected with behaviour problems. This study provides evidence for further investigation into the role of HRV in the pathophysiology of canine anxiety-related behaviour problems. Copyright © 2016. Published by Elsevier Inc.

    The success of antiretroviral therapy has led to dramatic changes in causes of morbidity and mortality among U.S. Veterans with human immunodeficiency virus (HIV). Among the 25,000 Veterans treated for HIV, 70% are over age 50 and the rate of obesity has doubled in this population. Veterans with HIV have a 50% increased risk of myocardial infarction yet have limited presence in prevention-related programs designed to lower cardiovascular disease risk. This mixed methods study (focus groups, Schwarzer and Renner physical activity, and nutrition self-efficacy questionnaires) was used to explore factors related to health behavior and identify barriers that overweight Veterans with HIV face in enrolling in the MOVE weight management program. Institutional review board approval was granted before the start of the study. All participants were recruited from the Infectious Disease clinic if they met national inclusion criteria for the MOVE weight management program and had not previously participated in the program. Transcribed audio recordings were independently analyzed and coded by four of the researchers using an exploratory process to obtain consensus regarding themes. An interrater reliability analysis for the Kappa statistic was performed to determine consistency among raters. The relationship between physical activity self-efficacy scores and nutrition self-efficacy scores was tested using Spearman's correlation coefficient. The median age of the sample was 56 with high rates of diabetes (36%), hypertension (73%), hyperlipidemia (36%), and tobacco use history (82%). External barriers to participation were discussed in addition to 8 other themes, which influence treatment engagement for Veterans with obesity and HIV including adaptation, stigma, self-management, and support. Veterans held strong beliefs about responsibility and commitment to their health and wanted to assume an active and informed role in their health care. Veterans with high levels of perceived

    The effect of age on the principal spectral components of heart rate obtained immediately after passive upright tilt was investigated in human subjects who underwent a 60-deg tilt over 9 sec. Two groups were examined, the first of which consisting of healthy male subjects aged 22-26 years, while the second was comprised of subjects aged 65-84 years on no medication; radiograms were recorded continuously beginning just prior to tilt until 3 min posttilt. The results of spectral analysis showed that elderly subjects did not exhibit the Mayer-like heart rate waves (the 0.07-0.09 Hz oscillations) that were present in the spectra of young subjects immediately after passive upright tilt. The findings are consistent with the concept of a 'dysautonomia of aging'. It is suggested that postural stress testing with spectral analysis of heart rate fluctuations may provide a useful way of assessing physiologic vs chronologic age.

    To compare the clinical presentation of children with anorexia nervosa (AN group) with that of children with low-weight food intake disorder without weight and shape-related psychopathology (non-AN group). Medical and psychiatric data were obtained from the case records of a consecutive series of 102 children with an eating disorder and a pronounced low weight who were below the age of 13 at the start of treatment. Fifty-eight patients constituted the AN group, and 44 constituted the non-AN group. The non-AN group was younger and had a longer duration of symptoms than the AN group. The non-AN group also had a lower maximum premorbid weight and shorter stature. There were no differences in medical severity, but the AN group had more psychiatric treatment. The non-AN group seems to have a medically equally severe disorder as the AN group, but is less often detected and properly treated.

    Full Text Available Background : Fatigue is the most common and distressing symptom reported by breast cancer survivors and yet the pathophysiology of cancer-related fatigue remains largely unknown. Fatigue is associated with lower parasympathetic and higher sympathetic nervous system activity in non-cancer samples, but only one study has demonstrated this same relationship in breast cancer survivors. This study evaluates the relationship between fatigue and basal autonomic nervous system activity as measured by heart rate variability (HRV in a sample of breast cancer survivors. Methods : Women who had been diagnosed with early stage breast cancer before the age of 50 were recruited from the UCLA tumor registry and completed psychological questionnaires, including measures of fatigue. A subset of these women (n=30 participated in a follow-up study in which they completed measures of fatigue, energy and mood four times per day for 5 days using electronic diaries, provided 3 days of saliva samples for cortisol assessment and underwent physiological assessment including electrocardiogram (ECG. HRV was assessed via ECG R-R wave spectral and time sequence analysis. Results : Questionnaire measures of fatigue were negatively associated with indices of parasympathetic nervous system activity, B= − 3.85, p = 0.04 for RMSSD (root of the mean squared difference of successive normal to normal waves and B= − 76.97, p = 0.04 for LF power % (low-frequency wave power percentage. Daily fatigue was also associated with lower basal HRV, B= − 15.1, p = 0.04 for RMSSD. However, fatigue indices were not associated with sympathetic nervous system activity as measured by low- to high-frequency wave ratio. Of note, fatigue was not associated with average daily cortisol output (AUC. Conclusions : Lower HRV has been associated with increased chronic inflammation, which is elevated in cancer survivors reporting persistent fatigue, thus providing insight into

    To evaluate the associations between population-wide loss and gain in weight with diabetes prevalence, incidence, and mortality, as well as cardiovascular and cancer mortality trends, in Cuba over a 30 year interval. Repeated cross sectional surveys and ecological comparison of secular trends. Cuba and the province of Cienfuegos, from 1980 to 2010. Measurements in Cienfuegos included a representative sample of 1657, 1351, 1667, and 1492 adults in 1991, 1995, 2001, and 2010, respectively. National surveys included a representative sample of 14 304, 22 851, and 8031 participants in 1995, 2001, and 2010, respectively. Changes in smoking, daily energy intake, physical activity, and body weight were tracked from 1980 to 2010 using national and regional surveys. Data for diabetes prevalence and incidence were obtained from national population based registries. Mortality trends were modelled using national vital statistics. Rapid declines in diabetes and heart disease accompanied an average population-wide loss of 5.5 kg in weight, driven by an economic crisis in the mid-1990s. A rebound in population weight followed in 1995 (33.5% prevalence of overweight and obesity) and exceeded pre-crisis levels by 2010 (52.9% prevalence). The population-wide increase in weight was immediately followed by a 116% increase in diabetes prevalence and 140% increase in diabetes incidence. Six years into the weight rebound phase, diabetes mortality increased by 49% (from 9.3 deaths per 10 000 people in 2002 to 13.9 deaths per 10 000 people in 2010). A deceleration in the rate of decline in mortality from coronary heart disease was also observed. In relation to the Cuban experience in 1980-2010, there is an association at the population level between weight reduction and death from diabetes and cardiovascular disease; the opposite effect on the diabetes and cardiovascular burden was seen on population-wide weight gain.

    Full Text Available OBJECTIVE: In order to determine the relationship between some maternal anthropometric indicators and birth weight, crown-heel length and newborn's head circumference, 92 pregnant women were followed through at the prenatal service of hospital in S. Paulo, Brazil. MATERIAL AND METHOD: The following variables were established for the mother: weight, height, mid-upper arm circumference, pre-pregnancy weight, gestational weight gain and Quetelet's index. For the newborn the following variables were recorded: birth weight, crown-heel length, head circumference and gestational age by Dubowitz's method. RESULTS: Significant associations were noted between gestational age and newborn variables. In addition, maternal mid-arm circumference (MUAC and pre-pregnancy weight were found to be positively correlated to birth weight (r=0.399; r=0.378, respectively. The multivariate linear regression shows that gestational age, mother's arm circumference and pre-pregnancy weight continue to be significant predictors of birth weight. On the other hand, only gestational age and mother's age was associated with crown-heel length. Similarly MUAC was significantly associated with crown-heel length (r= 0.306; P=0.0030. CONCLUSION: Maternal mid-upper arm circumference is a potential indicator of maternal nutritional status. It could be used in association with other anthropometric measurements, instead of pre-pregnancy weight, as an alternative indicator to assess women at risk of poor pregnancy outcome.

    The clinical challenges confronting patients with human immunodeficiency virus (HIV) have shifted from acquired immunodeficiency syndrome (AIDS)-related illnesses to chronic diseases, such as coronary artery disease, chronic lung disease, and chronic anemia. With the growing burden of HIV-related heart, lung, and blood (HLB) disease, the National Heart, Lung, and Blood Institute (NHLBI) recognizes it must stimulate and support HIV-related HLB research. Because HIV offers a natural, accelerated model of common pathological processes, such as inflammation, HIV-related HLB research may yield important breakthroughs for all patients with HLB disease. This paper summarizes the cardiovascular recommendations of an NHLBI Working Group, Advancing HIV/AIDS Research in Heart, Lung, and Blood Diseases, charged with identifying scientific priorities in HIV-related HLB disease and developing recommendations to promote multidisciplinary collaboration among HIV and HLB investigators. The working group included multidisciplinary sessions, as well as HLB breakout sessions for discussion of disease-specific issues, with common themes about scientific priorities and strategies to stimulate HLB research emerging in all 3 groups.

    The six-minute walk test (6 WT) is a valid and reliable predictor of morbidity and mortality in chronic heart failure (CHF) patients, frequently used as an endpoint or target in clinical trials. As opposed to spiroergometry, improvement of its prognostic accuracy by correction for height, weight, age and gender has not yet been attempted comprehensively despite known influences of these parameters. We recorded the 6 WT of 1035 CHF patients, attending clinic from 1995 to 2005. The 1-year prognostic value of 6 WT was calculated, alone and after correction for height, weight, BMI and/or age. Analysis was performed on the entire cohort, on males and females separately and stratified according to BMI (30 kg/m(2)). 6 WT weakly correlated with age (r=-0.32; p<0.0001), height (r=0.2; p<0.0001), weight (r=0.11; p<0.001), not with BMI (r=0.01; p=ns). The 6 WT was a strong predictor of 1-year mortality in both genders, both as a single and age corrected parameter. Parameters derived from correction of 6 WT for height, weight or BMI did not improve the prognostic value in univariate analysis for either gender. Comparison of the receiver operated characteristics showed no significant gain in prognostic accuracy from any derived variable, either for males or females. The six-minute walk test is a valid tool for risk prediction in both male and female CHF patients. In both genders, correcting 6 WT distance for height, weight or BMI alone, or adjusting for age, does not increase the prognostic power of this tool.

    The present study reports the lagged effects of work stress on work-related rumination, restful sleep, and nocturnal heart rate variability experienced during both workdays and weekends. Fifty employees participated in a diary study. Multilevel and regression analyses revealed a significant relationship between work stress measured at the end of a workday, work-related rumination measured during the evening, and restful sleep measured the following morning. Work stress, measured as the mean of 2 consecutive workdays, was substantially but not significantly related to restful sleep on weekends. Work stress was unrelated to nocturnal heart rate variability. Work-related rumination was related to restful sleep on weekends but not on workdays. Additionally, work-related rumination on weekends was positively related to nocturnal heart rate variability during the night between Saturday and Sunday. No mediation effects of work stress on restful sleep or nocturnal heart rate variability via work-related rumination were confirmed.

    Objective Severe obesity is the fastest growing pediatric subgroup of excess weight levels. Psychological dysregulation (i.e., impairments in regulating cognitive, emotional, and/or behavioral processes) has been associated with obesity and poorer weight loss outcomes. The present study explored associations of dysregulation with weight-related variables among adolescent and young adult (AYA) females with severe obesity. Methods Fifty-four AYA females with severe obesity (MBMI=48.71 kg/m2; Mage=18.29, R=15–21 years; 59.3% White) completed self-report measures of psychological dysregulation and weight-related constructs including meal patterns, problematic eating behaviors, and body and weight dissatisfaction, as non-surgical comparison participants in a multi-site study of adolescent bariatric surgery outcomes. Pearson and bivariate correlations were conducted and stratified by age group to analyze associations between dysregulation subscales (affective, behavioral, cognitive) and weight-related variables. Results Breakfast was the most frequently skipped meal (consumed 3–4 times/week). Eating out was common (4–5 times/week) and mostly occurred at fast-food restaurants. Evening hyperphagia (61.11%) and eating in the absence of hunger (37.04%) were commonly endorsed, while unplanned eating (29.63%), a sense of loss of control over eating (22.22%), eating beyond satiety (22.22%), night eating (12.96%), and binge eating (11.11%) were less common. Almost half of the sample endorsed extreme weight dissatisfaction. Dysregulation was associated with most weight-related attitudes and behaviors of interest in young adults but select patterns emerged for adolescents. Conclusions Higher levels of psychological dysregulation are associated with greater BMI, problematic eating patterns and behaviors, and body dissatisfaction in AYA females with severe obesity. These findings have implications for developing novel intervention strategies for severe obesity in AYAs that may

    to explore gestational weight gain in healthy women in relation to pre-pregnancy Body Mass Index, diet and physical activity. a cross-sectional survey was conducted among 455 healthy pregnant women of all gestational ages receiving antenatal care from an independent midwife in the Netherlands. Weight gain was assessed using the Institute of Medicine (IOM) guidelines and classified as below, within, or above the guidelines. A multinomial regression analysis was performed with weight gain classifications as the dependent variable (within IOM-guidelines as reference). Independent variables were pre-pregnancy Body Mass Index, diet (broken down into consumption of vegetables, fruit and fish) and physical activity (motivation to engage in physical activity, pre-pregnancy physical activity and decline in physical activity during pregnancy). Covariates were age, gestational age, parity, ethnicity, family income, education, perceived sleep deprivation, satisfaction with pre-pregnancy weight, estimated prepregnancy body mass index, smoking, having a weight gain goal and having received weight gain advice from the midwife. forty-two per cent of the women surveyed gained weight within the guidelines. Fourteen per cent of the women gained weight below the guidelines and 44 per cent gained weight above the guidelines. Weight gain within the guidelines, compared to both above and below the guidelines, was not associated with pre-pregnancy Body Mass Index nor with diet. A decline in physical activity was associated with weight gain above the guidelines (OR 0.54, 95 per cent CI 0.33-0.89). Weight gain below the guidelines was seen more often in women who perceived a greater sleep deprivation (OR 1.20, 95 per cent CI 1.02-1.41). Weight gain above the guidelines was seen less often in Caucasian women in comparison to non-Caucasian women (OR 0.22, 95 per cent CI 0.08-0.56) and with women who did not stop smoking during pregnancy (OR 0.49, 95 per cent CI 0.25-0.95). a decline in

    Pulmonary diffusion has been found to be reduced in patients with congestive heart failure. The effects of postural changes on the diffusing capacity had been evaluated in healthy subjects, but not in patients with heart failure. The aim of this study was to evaluate the posture-induced changes in diffusing capacity in patients with chronic heart failure and their relation to the hemodynamic profile. The pulmonary carbon monoxide diffusing capacity (DLCO) was measured in the supine position, with 20 degrees passive head elevation, and in the sitting position, both postures maintained for 10 min, in a group of 32 male patients with mild to moderate chronic heart failure due to left ventricular systolic dysfunction (ejection fraction differ in the two positions (20.3 +/- 5.7 vs. 19.4 +/- 5.6 ml/min/mm Hg, 77 +/- 23 vs. 75 +/- 20% of predicted, respectively). The patients were then subdivided according to changes in DLCO from the supine to the sitting position: DLCO increased (+23%) in 9 patients (28%, group 1), decreased (-17.5%) in 17 patients (53%, group 2), and remained within the coefficient of reproducibility ( +/- 5 %) in 6 patients (group 3). As compared with group 2, group 1 patients showed a significant increase in mean pulmonary artery pressure (+7 vs. -15%, p pressure (+8 vs. -22%, p position, while the cardiac index showed a smaller - but not significant - decrease in group 1 (-5 vs. -12%). The percent changes in DLCO significantly correlated with changes in pulmonary capillary wedge (r = 0.54, p pressures. In chronic heart failure postural changes may induce different responses in diffusing capacity. To a greater extent than in healthy subjects, the most common response is a decrease in DLCO in the sitting as compared with the supine position. The DLCO changes correlate with variations in pulmonary circulation pressure, probably due to changes in pulmonary vascular recruitment and pulmonary capillary blood volume.

    What are the effects of weight management interventions that include a diet component on weight-related outcomes in pregnant and postpartum women?The primary objective of this systematic review is to evaluate the effectiveness of weight management interventions which include a diet component and are aimed at limiting gestational weight gain and postpartum weight retention in women.The second objective of this systematic review is to investigate included intervention components with respect to effect on weight-related outcomes. This may include, but is not limited to: length of intervention, use of face-to-face counselling, group or individual consultations, use of other interventions components including exercise, use of goals and use of support tools like food diaries, coaching, including email or text message support. Around half of all women of reproductive age are either overweight or obese, with women aged 25-34 years having a greater risk of substantial weight gain compared with men of all ages. Excessive gestational weight gain (GWG) and postpartum weight retention (PPWR) may play a significant role in long term obesity. Having one child doubles the five- and 10-year obesity incidence for women, with many women who gain excessive weight during pregnancy remaining obese permanently. Excessive GWG and/or PPWR can also significantly contribute to short- and long-term adverse health outcomes for mother, baby and future pregnancies.Maternal obesity increases the risk of pregnancy related complications such as pre-eclampsia, gestational diabetes mellitus, stillbirth and the rate of caesarean section. Childhood obesity is a further long term complication of maternal obesity for offspring, which may persist in to adulthood. Excess GWG is also a risk factor for PPWR both in the short and long-term. Nehring et al. conducted a meta-analysis with over 65,000 women showing that, compared to women who gained weight within recommendations during pregnancy, women with GWG

    Respiratory syncytial virus (RSV) is a common pathogen causing acute respiratory infection in children. Herein, we describe the incidence and clinical and magnetic resonance imaging (MRI) findings of RSV-related encephalitis, a major neurological complication of RSV infection. We retrospectively reviewed the medical records and imaging findings of the patients over the past 7 years who are admitted to our medical center and are tested positive for RSV-RNA by reverse transcriptase PCR. In total, 3,856 patients were diagnosed with RSV bronchiolitis, and 28 of them underwent brain MRI for the evaluation of neurologic symptoms; 8 of these 28 patients had positive imaging findings. Five of these 8 patients were excluded because of non-RSV-related pathologies, such as subdural hemorrhage, brain volume loss due to status epilepticus, periventricular leukomalacia, preexisting ventriculomegaly, and hypoxic brain injury. The incidence of RSV-related encephalitis was as follows: 3/3,856 (0.08 %) of the patients are positive for RSV RNA, 3/28 (10.7 %) of the patient underwent brain MRI for neurological symptom, and 3/8 (37.5 %) of patients revealed abnormal MR findings. The imaging findings were suggestive of patterns of rhombenmesencephalitis, encephalitis with acute disseminated encephalomyelitis, and limbic encephalitis. They demonstrated no diffusion abnormality on diffusion-weighted image and symptom improvement on the follow-up study. Encephalitis with RSV bronchiolitis occurs rarely. However, on brain MRI performed upon suspicion of neurologic involvement, RSV encephalitis is not infrequently observed among the abnormal MR findings and may mimic other viral and limbic encephalitis. Physicians should be aware of this entity to ensure proper diagnosis and neurologic care of RSV-positive patients. (orig.)

    Purpose To evaluate a technique for simultaneous quantitative T2 and apparent diffusion coefficient (ADC) mapping in the heart (T2+ADC) using spin echo (SE) diffusion-weighted imaging (DWI). Theory and Methods T2 maps from T2+ADC were compared with single-echo SE in phantoms and with T2-prepared (T2-prep) balanced steady-state free precession (bSSFP) in healthy volunteers. ADC maps from T2+ADC were compared with conventional DWI in phantoms and in vivo. T2+ADC was also demonstrated in a patient with acute myocardial infarction (MI). Results Phantom T2 values from T2+ADC were closer to a single-echo SE reference than T2-prep bSSFP (−2.3 ± 6.0% vs 22.2 ± 16.3%; P T2 values from T2+ADC were significantly shorter than T2-prep bSSFP (35.8 ± 3.1 vs 46.8 ± 3.8 ms; P T2+ADC and conventional motion-compensated DWI (1.39 ± 0.18 vs 1.38 ± 0.18 mm2/ms; P = N.S.). In the patient, T2 and ADC were both significantly elevated in the infarct compared with remote myocardium (T2: 40.4 ± 7.6 vs 56.8 ± 22.0; P T2+ADC generated coregistered, free-breathing T2 and ADC maps in healthy volunteers and a patient with acute MI with no cost in accuracy, precision, or scan time compared with DWI.

    Overt hypothyroidism and hyperthyroidism may be associated with weight gain and loss. We assessed whether variations in thyroid function within the reference (physiologic) range are associated with body weight. Framingham Offspring Study participants (n=2407) who attended 2 consecutive routine examinations, were not receiving thyroid hormone therapy, and had baseline serum thyrotropin (TSH) concentrations of 0.5 to 5.0 mIU/L and follow-up concentrations of 0.5 to 10.0 mIU/L were included in this study. Baseline TSH concentrations were related to body weight and body weight change during 3.5 years of follow-up. At baseline, adjusted mean weight increased progressively from 64.5 to 70.2 kg in the lowest to highest TSH concentration quartiles in women (Pweight increased by 1.5 (5.6) kg in women and 1.0 (5.0) kg in men. Baseline TSH concentrations were not associated with weight change during follow-up. However, an increase in TSH concentration at follow-up was positively associated with weight gain in women (0.5-2.3 kg across increasing quartiles of TSH concentration change; Pweight in both sexes. Our findings raise the possibility that modest increases in serum TSH concentrations within the reference range may be associated with weight gain.

    To evaluate the perception of parents or caregivers on the health-related quality of life (HRQOL) of children/adolescents with overweight/obesity and possible factors associated with this perception. This was a cross-sectional study involving 297 caregivers of children and adolescents with normal weight (n=170) and with overweight/obesity (n=127), from public and private schools in the study municipality. HRQOL scores obtained through the Child Health Questionnaire - Parent Form 50 (CHQ-PF50) were compared according to the nutritional status and gender of the children/adolescents. Multiple regression analysis was used to determine the predictive value of studied variables for the variation in HRQOL scores. Parents of children/adolescents with overweight/obesity attributed lower HRQOL scores to their children in the following domains: physical functioning (pnutritional status (β=-0.18; p≤0.01); emotional impact on parents, impact on parents' time (β=0.31; pchildren/adolescents with overweight/obesity was observed in the physical and psychosocial aspects. The nutritional status was the variable with the greatest contribution for the assessment the self-esteem of children and adolescents in this study.

    2013-08-01

    The aim was to investigate relationships between activity related energy expenditure (AREE), appetite ratings and energy intake (EI) in a sample of 40 male (26.4years; BMI 23.5kg/m(2)) and 42 female (26.9years; BMI 22.4kg/m(2)) participants. AREE was expressed as the residual value of the regression between total daily EE (by doubly labeled water) and resting EE (by indirect calorimetry). EI was measured using an ad libitum buffet meal and visual analogue scales measured subjective appetite ratings before and after the meal. AREE was divided into low, middle and high sex-specific tertiles. General linear models were used to investigate differences in appetite ratings and EI across AREE tertiles. Before the meal, males in the high AREE tertile had significantly lower desire to eat and lower prospective food consumption and higher feelings of fullness compared to those in the low tertile. Males in the middle tertile had significantly higher satiety quotients after the meal and lower EI compared to the other tertiles. No significant differences across tertiles were found in females. Sex differences in relationships between AREE, appetite ratings and EI may lead to differing patterns of EI and subsequent weight maintenance. Copyright © 2013 Elsevier Ltd. All rights reserved.

    Excessive bodyweight contributes to a myriad of risk factors for chronic diseases, and multiple reports have demonstrated that parents influence the development of their children's behaviors that contribute to bodyweight. However, studies that include considerations for cultural influences are limited, and methodology that considers direct reports from young adults and their parents across cultures does not exist. A sample of young adults (N = 327) and their parents in the U.S. and in China were recruited and completed a series of questionnaires in two cycles (2010 and 2014). With correlation and multiple regression analyses, parents' characteristics, behaviors, and parental authority styles were examined and compared to weight-related health behaviors and bodyweight of their young-adult children. Additionally, similarities and differences of parental influences between the two cultures were explored. Parents' body mass indexes (BMIs) and dietary behaviors were positively associated with those of their young adult children in the mixed-culture sample (P permissive parental authority, the relationships between young adults' and their parents' BMIs were negative for U.S. participants and positive for Chinese participants (P parenting, the relationship between young adults' and their parents' dietary consumption behaviors was negative for U.S. participants and positive for Chinese participants (P development of life-long health behaviors that contribute to BMI are significantly influenced by parents' behaviors and parenting styles.

    We examined the incidence of ischemic lesions occurring after cerebral angiography by means of diffusion weighted MR imaging (DWI). Fifty patients were included in this study. Balloon occlusion tests of the internal carotid artery were performed in 9 of the 50 patients. DWI was performed on the same day as the cerebral angiography or on the following day. No new neurological deficits were found after cerebral angiography. However, 13 of the 50 cases revealed new ischemic lesions after cerebral angiography. The incidence of ischemic lesions was significantly different between patients who underwent balloon occlusion tests and patients who did not. The incidence of ischemic lesions was not influenced by the duration of the procedure, use of additional catheters, total amount of contrast material or the type of contrast material. The incidence of clinically silent ischemic lesions related to cerebral angiography is greater than the incidence of neurological complications. In patients who underwent occlusion tests of the internal carotid artery, the incidence of silent lesions was significantly higher than in patients who did not. (orig.)

    Full Text Available Examinations were made in 35 boys and 39 girls with extremely low birth weight in order to identify gender-related clinical and immunological features. A comparison group consisted of 31 full-term newborns with early uncomplicated adaptation. The investigators determined the number of lymphocyte subpopulations and cytokine-producing cells (CD3+INF-γ+, CD3+IL-4+ by flow cytometry and the serum levels of cytokines (IL-4, IFN-γ and neopterin by enzyme immunoassay. A study of immunological parameters revealed that the boys had a smaller number of CD3+, CD4+, and CD8+ subpopulations, a reduced content of CD3+IL-4+ cells at birth, and low IL-4 production on the first day of life compared to the full-term neonates. The girls were recorded to have higher levels of neopterin and B cells on the first day of life, the quantitative characteristics of T lymphocytes were consistent with those in the full-term infants. The findings are indicative of the greater functional immaturity of the immune system in the preterm boys.

    Coronary heart disease (CHD) is a disease that causes narrowing of the coronary arteries. Currently, there is a hypothesis regarding periodontal infection that increases risk for heart disease. Alkaline phosphatase (ALP) as a marker of inflammation will increase in atherosclerosis and periodontal disease. The objective of this research is analyzing the relationship between the levels of alkaline phosphatase in saliva with periodontal status in patients with CHD and non CHD. Here, saliva of 104 subjects were taken, each 1 ml, and levels of Alkaline Phosphatase was analyzed using Abbott ci4100 architect. We found that no significant difference of Alkaline Phosphatase levels in saliva between CHD patients and non CHD. Therefore, it can be concluded that Alkaline Phosphatase levels in patients with CHD saliva was higher than non CHD and no association between ALP levels with periodontal status.

    Most studies on patients' experiences following emergency cardiac surgery focus on evaluation of patients after their discharge. Few studies have evaluated patients' experiences after being transferred from intensive care and before being discharged. This study aimed to describe patients' experiences in the early stages of recovery following emergency heart surgery. For this exploratory qualitative descriptive study, 13 patients were recruited from a medical centre in northern Taiwan. Participants had undergone emergency heart surgery and had resided in the cardiothoracic surgical ward for ≥6 days following transfer from the ICU; all expected to be discharged from the hospital within 3 days. Semi-structured, face-to-face interviews were conducted in private after the patients had been transferred to the cardiothoracic surgical wards. Audiotaped interviews were transcribed and analysed using content analysis. Data analysis identified four themes, which represented different recovery stages: sudden and serious symptoms, nightmares and vivid dreams, physical and emotional disturbances, and establishing a new life after emergency surgery. A fifth theme, support for a new lifestyle, occurred between the four stages. Participants experienced symptoms of physical and psychological stress during the early recovery stages following emergency heart surgery. A lack of understanding of the process of recovery increased these difficulties; participants wanted and needed multidisciplinary care and education. Emergency heart surgery does not allow healthcare professionals to inform patients of what to expect post-surgery. Our findings suggest that rather than waiting until discharge to offer disease information and treatment plans, multidisciplinary care should be initiated as soon as possible to facilitate recovery.

    Traffic-related air pollution and noise are associated with cardiovascular diseases, and alternation of heart rate variability (HRV), which reflects cardiac autonomic function, is one of the mechanisms. However, few studies considered the impacts of noise when exploring associations between air pollution and HRV. We explored whether noise modifies associations between short-term exposure to traffic-related air pollution and HRV in young healthy adults. In this randomized, crossover study, 40 young healthy adults stayed for 2 h in a traffic center and, on a separate occasion, in a park. Personal exposure to traffic-related air pollutants and noise were measured and ambulatory electrocardiogram was performed. Effects were estimated using mixed-effects regression models. Traffic-related air pollution and noise were both associated with HRV, and effects of air pollutants were amplified at high noise level (>65.6 A-weighted decibels (dB[A])) compared with low noise level (≤ 65.6 dB[A]). High frequency (HF) decreased by -4.61% (95% confidence interval, -6.75% to-2.42%) per 10 μg/m(3) increment in fine particle (PM2.5) at 5-min moving average, but effects became insignificant at low noise level (P>0.05). Similar effects modification was observed for black carbon (BC) and carbon monoxide (CO). We conclude that noise is an important factor influencing the effects of air pollution on HRV.

    Full Text Available The patient was a 78-year-old man with dilated cardiomyopathy. His cardio-thoracic ratio was 60.4% and left ventricular ejection fraction (LVEF was 33%. He had been repeatedly admitted for congestive heart failure. He underwent implantation of an implantable cardioverter-defibrillator (ICD for ventricular fibrillation. We compared the values of BNP and shock impedance stored by the ICD. The correlation coefficient (p-value between BNP and shock impedance was −0.700 (p < 0.0005, increase of BNP and shock impedance was −0.778 (p < 0.0001, percent increase of BNP and shock impedance was −0.767 (p < 0.0005. In conclusion, there is an inverse relation between BNP and shock impedance, and measurements of shock impedance may be useful in the management of congestive heart failure.

    Full Text Available The present study investigates the role that shape and color play in the representation of animate (i.e. animals and inanimate manipulable entities (i.e. fruits, and how the importance of these features is modulated by different tasks. Across three experiments participants were shown either images of entities (e.g., a sheep or a pineapple or images of the same entities modified in color (e.g. a blue pineapple or in shape (e.g. an elongated pineapple. In Experiment 1 we asked participants to categorize the entities as fruit or animal. Results showed that with animals color does not matter, while shape modifications determined a deterioration of the performance - stronger for fruit than for animals. To better understand the findings, in Experiment 2 participants were asked to judge if entities were graspable (manipulation evaluation task. Participants were faster with manipulable entities (fruit than with animals; moreover alterations in shape affected the response latencies more for animals than for fruit. In Experiment 3 (motion evaluation task, we replicated the disadvantage for shape-altered animals, while with fruits shape and color modifications produced no effect. By contrasting shape- and color- alterations the present findings provide information on shape/color relative weight, suggesting that the action based property of shape is more crucial than color for fruit categorization, while with animals it is critical for both manipulation and motion tasks. This contextual dependency is further revealed by explicit judgments on similarity - between the altered entities and the prototypical ones - provided after the different tasks. These results extend current literature on affordances and biofunctionally embodied understanding, revealing the relative robustness of biofunctional activity compared to intellectual one.

    Healthcare professionals have called for direction on how best to communicate about weight-related topics with children and families. Established scoping review methodology was used to answer the question: 'How can healthcare professionals best communicate with children and their families about obesity and weight-related topics?' We searched four scientific databases, two grey literature repositories and 14 key journals (2005-2016). Inclusion criteria were (i) children up to and including 18 years of age and/or their parents; (ii) communication about healthy weight, overweight, obesity or healthy/active living; and (iii) healthcare setting. Thirty-two articles were included. Evidence-based best practices were largely absent from the literature, although the following guiding principles were identified: (i) include all stakeholders in discussions; (ii) raise the topic of weight and health early and regularly; (iii) use strengths-based language emphasizing health over weight; (iv) use collaborative goal-setting to engage children and parents and (v) augment discussions with appropriate tools and resources. Guidance on how to implement these principles and how to negotiate relevant contextual factors (e.g. age, culture and disability) is still needed. Despite agreement on a number of guiding principles, evidence-based weight-related communication best practices are lacking. Rigorous, empirical evaluations of communication approaches are urgently required, especially those that include children's perspectives. © 2016 World Obesity Federation.

    Full Text Available Abstract Background: Today, the high prevalence of diabetes and its complications are one of the most important public health issues worldwide. For this reason, finding relations between diabetes risk factors is very effective in preventing and reducing complications. For discovering these relations, the data mining methods can be used. By extracting association rules, which is one of the data mining techniques, we can discover the relations between a large numbers of variables in a disease. Materials and Methods: The population of this study was 1046 patients with type 2 diabetes, whose data had recorded between 2011 and 2014 at the Special Clinic for Diabetes in Tehran's Imam Khomeini Hospital. After pre-processing step with SPSS19 software, 573 people entered the analysis phase. The FP-Growth algorithm was applied to the data set to discover the relations between heart attack and other risk factors using Rapid miner5 software. Relations, after extraction, were given to the doctor to confirm clinical validation. Results: The obtained results of studying these 573 people (Including 292 (51% women and 281 (49% men, with age range 27 to 82 years showed that the lack of blood pressure, creatinine and diastolic blood pressure at its normal level, despite higher systolic blood pressure level than normal, doesn't increase the probability of heart attack. Conclusion: Using association rules is a good way of identifying relations between the risk factors of a disease. Also, it can provide new hypotheses to do epidemiological studies for researchers.

    Full Text Available Diabetes mellitus (DM is one of the most influential risk factors for the development of cardiovascular diseases. Incidence of coronary heart diseases (CHD and acute myocardial infarction in diabetic patients is much higher than in people without diabetes. Type 2 DM affects other risk factors of CHD due to the fact that, as a rule, it is accompanied by obesity, hypertension, hypertriglyceridemia and decrease of high density lipoproteins. Purpose of the investigation – to improve the efficiency of treatment of patients with CHD with type 2 DM based on the effect of Simvastatin and Korargin on it’s clinical course, body weight and the distribution of adipose tissue. Materials and methods of the investigation. The study involved 175 patients with CHD aged from 34 to 87, mean age was 61,0 ± 8,0 years, among whom there were 96 (54,9% men and 79 (45,1% women. All surveyed received conventional treatment. Depending on supplementary prescriptions patients were divided into eight groups: 1 group - 22 patients with CHD who were prescribed Simvastatin, 2 group - 20 patients with CHD who were prescribed Korargin, 3 group - 20 patients with coronary artery disease who were prescribed simultaneously both Simvastatin and Korarhin, 4 group - 20 patients with CHD with type 2 diabetes treated with Simvastatin, 5 group - 23 patients with CHD with type 2 diabetes who took Korargin, 6 group - 27 patients with CHD with type 2 diabetes, who were prescribed both Simvastatin and Korargin in addition to conventional treatments, 7 group - 20 patients with CHD who received only conventional treatments, 8 group - 23 patients with coronary artery disease combined with type 2 diabetes who received only conventional treatments.

    To evaluate the apparent diffusion coefficient (ADC) values between multiple sclerosis (MS) and neuromyelitis optica (NMO)-related acute optic neuritis (ON) patients and predict their optic nerve atrophy of optic coherence tomography (OCT) parameters. Nineteen MS and 15 NMO-related acute ON patients who underwent a diffusion-weighted imaging sequence in 3.0 Tesla MR scanner and a follow-up OCT examination after 6 months were included. The ADC values, thickness of the retinal nerve fiber layer (RNFL) and the macular ganglion cell complex (GCC) between MS and NMO related ON were assessed. The mean ADC value of the NMO-ON, (0.691 ± 0.195[SD]) × 10 -3 mm 2 /s, was significantly smaller (P = 0.0133) than that of MS-ON. The mean ADC value of MS-ON, (0.879 ± 0.144) × 10 -3 mm 2 /s, was significantly smaller (P < 0.0001) than that of control group, (1.025 ± 0.067) × 10 -3 mm 2 /s. Using an ADC value smaller than 0.830 × 10 -3 mm 2 /s as the threshold value for differentiating MS-ON from NMO-ON patients, the highest accuracy of 76.7%, with 75.0% sensitivity and 78.3% specificity, was obtained. The ADC value measured at the acute stage of ON was correlated with the thickness of the RNFL (r = 0.441; P = 0.006) and the GCC (r = 0.526; P < 0.0001) after 6 months. The ADC value might be helpful for differentiating MS-ON from NMO-ON patients. The decreased ADC value was correlated with optic nerve atrophy on OCT. 3 Technical Efficacy: Stage 2 J. MAGN. RESON.

    To investigate how socio-economic position, demographic factors, degree of integration and dietary indicators are related to BMI/waist:hip ratio (WHR) and to weight dissatisfaction and slimming among South Asians in Oslo, Norway. Cross-sectional study consisting of a health check including anthropometric measures and two self-administered questionnaires. Oslo, Norway. Pakistanis and Sri Lankans (n 629), aged 30-60 years, residing in Oslo. BMI was positively associated with female gender (P = 0.004) and Pakistani origin (P integration (measured by a composite index, independent of duration of residence; P = 0.017). One-third of those with normal weight and most of those obese were dissatisfied with their weight. Among these, about 40 % had attempted to slim during the past year. Dissatisfaction with weight was positively associated with education in women (P = 0.006) and with integration in men (P = 0.026), and inversely associated with physical activity (P = 0.044) in men. Women who had made slimming attempts had breakfast and other meals less frequently than others (P < 0.05). Weight dissatisfaction exists among South Asian immigrants. More research is needed regarding bodily dissatisfaction and the relationship between perception of weight and weight-change attempts among immigrants in Norway, in order to prevent and treat both obesity and eating disorders.

    In a previous study, we showed that saccharin can induce weight gain when compared with sucrose in Wistar rats despite similar total caloric intake. We now question whether it could be due to the sweet taste of saccharin per se. We also aimed to address if this weight gain is associated with insulin-resistance and to increases in gut peptides such as leptin and PYY in the fasting state. In a 14 week experiment, 16 male Wistar rats received either saccharin-sweetened yogurt or non-sweetened yogurt daily in addition to chow and water ad lib. We measured daily food intake and weight gain weekly. At the end of the experiment, we evaluated fasting leptin, glucose, insulin, PYY and determined insulin resistance through HOMA-IR. Cumulative weight gain and food intake were evaluated through linear mixed models. Results showed that saccharin induced greater weight gain when compared with non-sweetened control (p = 0.027) despite a similar total caloric intake. There were no differences in HOMA-IR, fasting leptin or PYY levels between groups. We conclude that saccharin sweet taste can induce mild weight gain in Wistar rats without increasing total caloric intake. This weight gain was not related with insulin-resistance nor changes in fasting leptin or PYY in Wistar rats. Copyright © 2015 Elsevier Ltd. All rights reserved.

    Background: Coronary diseases appear to result from an overbalance between radical-generating, compared with radical-scavenging systems, a condition called as oxidative stress. Total antioxidant status (TAS) in human plasma reflects the balance between oxidants and antioxidants in each system. Bilirubin has been considered an antioxidant, with capacity to remove reactive species of oxygen. Present study tried to measure the total antioxidant status of first degree relatives of patients with IHD. Study also tried to evaluate the prognostic role of serum bilirubin in disease prevention or progression. Methods: Seventy five apparently healthy subjects in age group 20-50 years, comprising equal number of males and females, who were first degree relatives of ischemic heart disease patients, were included in the study. Family members were divided on the bases of their numbers, i.e., one family member (Group-A), 2 family members (Group-B) and more than 3 family members (Group-C). Study was cross sectional and carried out in a period of 6 months (Jun 2008-Jan 2009). Subjects with letter of consent were taken from general population. Seventy five healthy age matched people with no history of ischemic heart disease in family were taken as control. An overnight fasting blood sample was taken. Total antioxidant status was determined using a commercially available kit. Serum bilirubin was estimated by auto analyzer. Results: Family history of ischemic heart disease with serum bilirubin showed a significant negative correlation (p<0.05). But the values of TAS failed to show any significant correlation with the family history. It was observed that the value of serum bilirubin was decreased significantly (p<0.05) with an increased number of family members. Total antioxidant status failed to show any significant difference among all the three groups. Conclusion: Our data demonstrated that reduced serum levels of bilirubin were seen in people with a higher prevalence of coronary

    Obese dogs seem to have a different gut microbiome (GM) composition compared to lean dogs, and in humans, GM composition may negatively impact the ability to lose weight in some individuals. The purpose of this study was to investigate the interaction between exercise, weight......-loss and the composition of GM in dogs. Eighteen obese pet dogs were recruited for a 12-week weight-loss intervention. All dogs were fed restrictively with a commercial high-protein/high-fibre dry diet, and eight of these dogs were enrolled in an exercise program in addition to the diet intervention. Faecal samples were...... collected and the dogs were weighed at week 0, week 6 and week 12. GM composition was determined using MiSeq-based tag-encoded 16S rRNA gene high-throughput amplicon sequencing, and concentrations of short chain fatty acids (SCFA) by gas-liquid chromatography. Total weight loss, food allowance and GM were...

    Given that immature and adult insects have different life styles, different target body compositions can be expected. For adults, such targets will also differ depending on life history strategy, and thus vary among the sexes, and in females depend on the degree of capital versus income breeding and ovigeny. Since these targets may in part be approximated by loss of substances upon eclosion, comparing sexual differences in such losses upon eclosion among species that differ in life history would provide insights into insect functional ecology. We studied weight loss in eclosing insects using original data on pupal and adult live weights of 38 species of Lepidoptera (mainly Geometridae) and further literature data on 15 species of Lepidoptera and six representatives of other insect orders, and applied the phylogenetic independent contrasts approach. In addition, data on live and dry weights of pupae of four species of Lepidoptera are presented. We documented that Lepidoptera typically lose a large proportion (20-80%) of their pupal weight upon adult eclosion. Sexual differences in weight loss varied between absent and strongly male biased. Most of the weight loss was water loss, and sexual differences in adult water content correlate strongly with differences in weight loss. Using feeding habits (feeds or does not feed as an adult) and female biased sexual size dimorphism as measures of degree of capital breeding, we found that the difference among the sexes in weight loss tends to be more pronounced in capital breeding species. Additionally, females of more pro-ovigenic species (large proportion of eggs mature upon emergence) tend to have higher water contents. Our results suggests that metamorphosis is generally facilitated by a high water content, while adults excrete water upon eclosion to benefit flight unless water has been allocated to eggs, or is treated as a capital resource for adult survival or future allocation to eggs.

    Full Text Available Women tend to gain weight at midlife (40–60 years increasing risk of obesity-related chronic diseases. Within specific eating occasions, needs related to the physical and social environment may result in less healthy eating behavior, which can lead to weight gain over time. The purpose of this study was to determine if a dietitian-delivered nutrition counseling intervention tailored to eating occasion needs could improve diet and prevent weight gain among midlife women over two years. A randomized controlled trial was conducted with healthy midlife women (n = 354 in one U.S. metropolitan area. The intervention group (n = 185 received ten hours of individual nutrition counseling from dietitians over six months, while women in a control group (n = 169 received no counseling. Measured height, weight and waist circumference, and dietary intakes were collected at baseline and every six months over two years. Mixed linear models were used to test for intervention effect on change in outcome variables over time. Dietary intakes of fruit, reduced/low-fat dairy foods and refined grains were significantly improved over time in the intervention compared to control group. However, the intervention had no effect on weight over time (p = 0.48. Nutrition counseling tailored to address eating occasion needs improved self-reported diet but did not significantly affect weight change.

    We have recently synthesized a new series of 4,5-dihydrobenzo-oxa-cycloheptapyrazole derivatives with the aim to discover novel CB1 antagonist agents characterized by anti-obesity activity comparable to that of SR141716A but with reduced adverse effects such as anxiety and depression. Within the novel class, the CB1 antagonist 8-chloro-1-(2,4-dichlorophenyl)-N-piperidin-1-yl-4,5-dihydrobenzo-1H-6-oxa-cyclohepta(1,2-c)pyrazole-3-carboxamide (NESS06SM) has been selected as lead compound. We found that NESS06SM is a CB1 neutral antagonist, characterized by poor blood-brain barrier permeability. Moreover, NESS06SM chronic treatment determined both anti-obesity effect and cardiovascular risk factor improvement in C57BL/6N Diet Induced Obesity (DIO) mice fed with fat diet (FD mice). In fact, the mRNA gene expression in Central Nervous System (CNS) and peripheral tissues by real time PCR, showed a significant increase of orexigenic peptides and a decrease of anorexigenic peptides elicited by NESS06SM treatment, compared to control mice fed with the same diet. Moreover, in contrast to SR141716A treatment, the chronic administration of NESS06SM did not change mRNA expression of both monoaminergic transporters and neurotrophins highly related with anxiety and mood disorders. Our results suggest that NESS06SM reduces body weight and it can restore the disrupted expression profile of genes linked to the hunger-satiety circuit without altering monoaminergic transmission probably avoiding SR141716A side effects. Therefore the novel CB1 neutral antagonist could represent a useful candidate agent for the treatment of obesity and its metabolic complications. Copyright © 2013 Elsevier Ltd. All rights reserved.

    2002-01-01

    Full Text Available OBJECTIVE: To assess the relation between P-wave and QT dispersions in elderly patients with heart failure. METHODS: Forty-seven elderly patients (75.6±6 years with stable heart failure in NYHA functional classes II or III and with ejection fractions of 37±6% underwent body surface mapping to analyze P-wave and QT dispersions. The degree of correlation between P-wave and QT dispersions was assessed, and P-wave dispersion values in patients with QT dispersion greater than and smaller than 100 ms were compared. RESULTS: The mean values of P-wave and QT dispersions were 54±14 ms and 68±27 ms, respectively. The correlation between the 2 variables was R=0.41 (p=0.04. In patients with QT dispersion values > 100 ms, P-wave dispersion was significantly greater than in those with QT dispersion values < 100 ms (58±16 vs 53±12 ms, p=0.04 . CONCLUSION: Our results suggest that, in elderly patients with heart failure, a correlation between the values of P-wave and QT dispersions exists. These findings may have etiopathogenic, pathophysiologic, prognostic, and therapeutic implications, which should be investigated in other studies.

    Full Text Available Objective: Prolyl carboxypeptidase (PRCP plays a role in the regulation of energy metabolism by inactivating hypothalamic α-melanocyte stimulating hormone (α-MSH levels. Although detected in the arcuate nucleus, limited PRCP expression has been observed in the arcuate POMC neurons, and its site of action in regulating metabolism is still ill-defined. Methods: We performed immunostaining to assess the localization of PRCP in arcuate Neuropeptide Y/Agouti-related Peptide (NPY/AgRP neurons. Hypothalamic explants were then used to assess the intracellular localization of PRCP and its release at the synaptic levels. Finally, we generated a mouse model to assess the role of PRCP in NPY/AgRP neurons of the arcuate nucleus in the regulation of metabolism. Results: Here we show that PRCP is expressed in NPY/AgRP-expressing neurons of the arcuate nucleus. In hypothalamic explants, stimulation by ghrelin increased PRCP concentration in the medium and decreased PRCP content in synaptic extract, suggesting that PRCP is released at the synaptic level. In support of this, hypothalamic explants from mice with selective deletion of PRCP in AgRP neurons (PrcpAgRPKO showed reduced ghrelin-induced PRCP concentration in the medium compared to controls mice. Furthermore, male PrcpAgRPKO mice had decreased body weight and fat mass compared to controls. However, this phenotype was sex-specific as female PrcpAgRPKO mice show metabolic differences only when challenged by high fat diet feeding. The improved metabolism of PrcpAgRPKO mice was associated with reduced food intake and increased energy expenditure, locomotor activity, and hypothalamic α-MSH levels. Administration of SHU9119, a potent melanocortin receptor antagonist, selectively in the PVN of PrcpAgRPKO male mice increased food intake to a level similar to that of control mice. Conclusions: Altogether, our data indicate that PRCP is released at the synaptic levels and that PRCP in AgRP neurons contributes to

    Little is known about how factors within the general family environment are associated with weight and related behaviors among adolescents/young adults. We studied 3768 females and 2614 males, 14-24 years old in 2011, participating in the Growing Up Today Study 2. We used generalized mixed models to examine cross-sectional associations of family functioning and quality of mother- and father-adolescent relationship with adolescent/young adult weight status, disordered eating, intake of fast food and sugar-sweetened beverages, screen time, physical activity, and sleep duration. In all models, we included participant's age and family structure. Eighty percent of participants reported high family functioning and 60% and 50% of participants reported high-quality mother and father relationship, respectively. Among both males and females, high family functioning was associated with lower odds of disordered eating (adjusted odds ratio [AOR] females = 0.53; 95% Confidence Interval [CI] = 0.45-0.63; AOR males = 0.48; CI = 0.39-0.60), insufficient physical activity, i.e., less than 1 h/day, (AOR females = 0.74; CI = 0.61-0.89; AOR males = 0.73; CI = 0.58-0.92), and insufficient sleep, i.e., less than 7 h/day, (AOR females = 0.56; CI = 0.45-0.68; AOR males = 0.65; CI 0.5-0.85). High family functioning was also associated with lower odds of being overweight/obese (AOR = 0.73; CI = 0.60-0.88) and eating fast food one or more times/week (AOR = 0.74; CI = 0.61-0.89) among females only. Among females, high-quality mother and father relationship were both associated with lower odds of being overweight/obese and disordered eating, eating fast food, and insufficient sleep and the magnitude of associations were similar for mother and father relationship quality (AOR range 0.61-0.84). Among males, high-quality mother and father relationship were both associated with lower odds of disordered eating, insufficient physical activity

    To describe the frequency, characteristics, and outcomes of heart failure-related emergency department (ED) visits in pediatric patients. We aimed to test the hypothesis that these visits are associated with higher admission rates, mortality, and resource utilization. A retrospective analysis of the Nationwide Emergency Department Sample for 2010 of patients ≤18 years of age was performed to describe ED visits with and without heart failure. Cases were identified using International Classification of Disease, Ninth Revision, Clinical Modification codes and assessed for factors associated with admission, mortality, and resource utilization. Among 28.6 million pediatric visits to the ED, there were 5971 (0.02%) heart failure-related cases. Heart failure-related ED patients were significantly more likely to be admitted (59.8% vs 4.01%; OR 35.3, 95% CI 31.5-39.7). Among heart failure-related visits, admission was more common in patients with congenital heart disease (OR 5.0, 95% CI 3.3-7.4) and in those with comorbidities including respiratory failure (OR 78.3, 95% CI 10.4-591) and renal failure (OR 7.9, 95% CI 1.7-36.3). Heart failure-related cases admitted to the hospital had a higher likelihood of death than nonheart failure-related cases (5.9% vs 0.32%, P failure (OR 4.5, 95% CI 2.2-9.2) and renal failure (OR 7.8, 95% CI 2.9-20.7). Heart failure-related ED visits were more expensive than nonheart failure-related ED visits ($1460 [IQR $861-2038] vs $778 [IQR $442-1375] [P failure-related visits represent a minority of pediatric ED visits but are associated with increased hospital admission and resource utilization.

    Full Text Available Objective: An investigation of the interplay between various types of adolescents’ perceptions of weight status in predicting adolescents’ nutrition behavior and their body weight was conducted. In particular, it was hypothesized that the relationship between parental and peers’ perceptions of their own weight status (reported by adolescents and objectively measured weight status of adolescents would be mediated by three types of adolescents’ weight status perceptions (adolescents’ own weight perceptions, parental perceptions of adolescents’ weight status perceived by participants, and peers’ perceptions of adolescents’ weight status perceived by participants and by adolescents’ nutrition behaviors. Design: Data were collected twice, with a 13-month follow-up. Participants (N = 1096 were aged 14-20, with BMI ranging from 16.20 to 41.21. Multiple mediation analysis with two sequential mediators was applied.Main outcome measures: At the baseline adolescents completed the questionnaire assessing their nutrition behaviors and weight status perceptions. Weight and height were measured objectively at baseline and follow-up.Results: Two types of weight perceptions (adolescents’ own weight status perceptions, peers’ perceptions of adolescents’ weight status reported by participants, and adolescents’ nutrition behaviors mediated the relationship between the others’ own weight perceptions and adolescents’ weight status. No indirect effects of others’ own weight perceptions on adolescents’ weight status through parental perceptions were found.Conclusion: Adolescents’ nutrition behaviors and body weight status depend on what they think about their own weight status and what they think of their peers’ perceptions, but do not depend on what adolescents think of their parents’ perceptions.

    The aim of this study was to investigate the relation between health-related physical fitness and weight status in 13- to 15-year-old Latino adolescents. The final sample consisted of 73,561 adolescents aged 13-15 years (35,175 girls) from Chile (n=48,771) and Colombia (n=24,790). Cardiorespiratory and musculoskeletal fitness were measured using 20-m shuttle run (relative peak oxygen uptake - VO 2peak ) and standing broad jump test (lower body explosive strength), respectively. The International Obesity Task Force definition was used to define weight status (i.e., underweight, normal weight, overweight, and obese). The present study found an inverted J-shape relationship between body mass index, cardiorespiratory fitness, and musculoskeletal fitness in both genders and all age groups (pfitness (based on new international criterion-referenced standards) profile when compared with their normal weight peers, except in girls aged 14 (p=0.268) and 15 years (p=0.280). The present results indicate low cardiorespiratory fitness and musculoskeletal fitness levels in underweight, overweight, and obese adolescents when compared with their normal weight peers. The findings appear to suggest that exercise programs should to decrease fat mass in overweight/obese adolescents and increase muscle mass in underweight adolescents.

    Findings have been inconsistent on effects of adolescent body size and adult weight gain on risk of breast cancer in young women. These relations were examined in a population-based case control study of 1590 women less than 45 years of age newly diagnosed with breast cancer during 1990-1992 in three areas of the US and an age-matched control group of 1390 women. Height and weight were measured at interview and participants asked to recall information about earlier body size. Logistic regression was used to estimate the relative risk of breast cancer adjusted for other risk factors. Women who were either much heavier or lighter than average in adolescence or at age 20 were at reduced risk. Weight gain after age 20 resulted in reduced risk, but the effect was confined to early-stage and, more specifically, lower grade breast cancer. Neither the risk reduction nor the variation by breast cancer stage or grade was explained by the method of cancer detection or by prior mammography history. These findings suggest that relations between breast cancer risk in young women and body weight at different ages is complex and that the risk reduction with adult weight gain is confined to less aggressive cancers.

    Parrotfishes (family Labridae: Scarini) are regarded to have important roles for maintaining the ecosystem balance in coral reefs due to their removal of organic matter and calcic substrates by grazing. The purpose of the present study was to clarify the interspecific differences in grazing ability of five parrotfish species (Chlorurus sordidus, C. bowersi, Scarus rivulatus, S. niger and S. forsteni) in relation to interspecific differences in jaw-lever mechanics and the relative weight of the adductor mandibulae (muscles operating jaw closing). The grazing ability was calculated by using stomach contents (CaCO3 weight/organic matter weight) defined as the grazing ability index (GAI). There were significant interspecific differences in GAI (C. sordidus = C. bowersi > S. rivulatus > S. niger = S. forsteni). Teeth of C. sordidus and C. bowersi were protrusive-shape whereas teeth of S. rivulatus, S. niger and S. forsteni were flat-shape. C. sordidus and C. bowersihave jaw-lever mechanics producing a greater biting force and have a larger weight of adductor mandibulae. S. rivulatus has jaw-lever mechanics producing a greater biting force but a smaller weight of adductor mandibulae that produce an intermediate biting force. In contrast, S. niger and S. forsteni have jaw-lever mechanics producing a lesser biting force and have a smaller weight of adductor mandibulae. Feeding rates and foray size of S. rivulatus, S. niger and S. forsteni were greater than C. sordidus and C. bowersi. The degree in bioerosion (GAI × feeding rate) was the largest for S. rivulatusand the smallest for S. forsteni. The degree in bioerosion for C. sordidus was larger than S. niger whereas relatively equal between C. bowersi and S. niger. These results suggest that interspecific difference in GAI was explained by interspecific differences in teeth shape, jaw-lever mechanics and relative weight of adductor mandibulae. The interspecific difference in the degree of bioerosion suggests the

    To assess links between comorbid health status, severe excess weight, and weight-related quality of life (WRQOL) in adolescents with severe obesity and undergoing weight-loss surgery (WLS) to inform clinical care. Baseline (preoperative) data from Teen Longitudinal Assessment of Bariatric Surgery, a prospective multicenter observational study of 242 adolescents with severe obesity (MedianBMI = 50.5 kg/m(2); Meanage = 17.1; 75.6% female; 71.9% white) undergoing WLS, were used to examine the impact of demographics, body mass index (BMI), presence/absence of 16 comorbid conditions, and a cumulative comorbidity load (CLoad) index on WRQOL scores (Impact of Weight on Quality of Life-Kids). WRQOL was significantly lower than reference samples of healthy weight, overweight, and obese samples. Of 16 comorbid conditions, the most prevalent were dyslipidemia (74.4%), chronic pain (58.3%), and obstructive sleep apnea (56.6%). Male subjects had a greater CLoad (P = .01) and BMI (P = .01), yet less impairment in total WRQOL (P conditions (eg, stress urinary incontinence) also emerged as contributors to lower WRQOL. WRQOL impairment is substantial for adolescents with severe obesity undergoing WLS, with predictors varying by sex. These patient-data highlight targets for education, support, and adjunctive care referrals before WLS. Furthermore, they provide a comprehensive empirical base for understanding heterogeneity in adolescent WRQOL outcomes after WLS, as weight and comorbidity profiles change over time.

    2016-02-01

    Excessive weight gain and physical inactivity in pregnancy have been identified as risk factors for negative health outcomes for mothers and fetuses, particularly among Aboriginal women. In this paper we engage with postcolonial feminist theory and critical discourse analysis to examine the question, "how do urban Aboriginal women understand pregnancy-related weight gain and physical activity." We conducted focus groups and semi-structured interviews with 25 urban Aboriginal pregnant or postpartum women between the ages of 16 and 39 in Ottawa, Canada. Three prominent discourses emerged: Aboriginal women have different pregnancies than non-Aboriginal women because Aboriginal women gain more weight and are more likely to develop gestational diabetes; Aboriginal women feel personally responsible for and shameful about excessive weight gain; finally, Aboriginal women need culturally safe pregnancy resources. Our results illuminate the complex and often paradoxical ways in which discourses around weight gain and physical activity are produced and taken-up by Aboriginal women and their healthcare providers. Based on these findings, we argue there is a lack of accessible and culturally safe resources for urban Aboriginal women, specifically concerning weight gain and physical activity in pregnancy. We recommend the development of resources that are created for/by/with Aboriginal women to better address that issues that urban Aboriginal women themselves identify as being of key importance.

    Obsession with thinness and body dissatisfaction can lead adolescents to follow unsupervised diets, which could result in risky weight control behaviors such as fasting, vomiting, use of diuretics and laxatives. The aim of the current study is to examine weight control behaviors in dieting adolescents and relate them to body dissatisfaction (BD) and obsession with thinness (OT). A cross-sectional study was conducted on 439 adolescents from Valparaiso public schools to investigate risky weight control behaviors due to BD and OT scales from the Eating Disorders Inventory-2 (EDI-2), comparing restrained eaters and non-restrained eaters. A total of 43% adolescents had followed a weight loss diet without medical supervision. The dieters had higher BD and OT values. Moderate to severe food restriction, based on expert judgment, was observed in 29.6%, and differences in the presence and severity of purging behaviors were found between the 2 groups. One third of the adolescents studied followed diets without professional supervision and had higher BD and OT values, as well as risky weight control behaviors. Overweight and obese adolescents followed more restrictive diets and developed riskier weight control behaviors. Copyright © 2015. Publicado por Elsevier España, S.L.U.

    Severe obesity is the fastest growing pediatric subgroup of excess weight levels. Psychological dysregulation (i.e., impairments in regulating cognitive, emotional, and/or behavioral processes) has been associated with obesity and poorer weight loss outcomes. The present study explored associations of dysregulation with weight-related variables among adolescent and young adult (AYA) females with severe obesity. Fifty-four AYA females with severe obesity (MBMI = 48.71 kg/m(2); Mage = 18.29, R = 15-21 years; 59.3% White) completed self-report measures of psychological dysregulation and weight-related constructs including meal patterns, problematic eating behaviors, and body and weight dissatisfaction, as non-surgical comparison participants in a multi-site study of adolescent bariatric surgery outcomes. Pearson and bivariate correlations were conducted and stratified by age group to analyze associations between dysregulation subscales (affective, behavioral, cognitive) and weight-related variables. Breakfast was the most frequently skipped meal (consumed 3-4 times/week). Eating out was common (4-5 times/week) and mostly occurred at fast-food restaurants. Evening hyperphagia (61.11%) and eating in the absence of hunger (37.04%) were commonly endorsed, while unplanned eating (29.63%), a sense of loss of control over eating (22.22%), eating beyond satiety (22.22%), night eating (12.96%), and binge eating (11.11%) were less common. Almost half of the sample endorsed extreme weight dissatisfaction. Dysregulation was associated with most weight-related attitudes and behaviors of interest in young adults but select patterns emerged for adolescents. Higher levels of psychological dysregulation are associated with greater BMI, problematic eating patterns and behaviors, and body dissatisfaction in AYA females with severe obesity. These findings have implications for developing novel intervention strategies for severe obesity in AYAs that may have a multidimensional

    To assess health related quality of life of patients with congestive heart failure; to compare their quality of life with the previously characterised general population and in those with other chronic diseases; and to correlate the different aspects of quality of life with relevant somatic variables. University hospital. A German version of the generic quality of life measure (SF-36) containing eight dimensions was administered to 205 patients with congestive heart failure and systolic dysfunction. Cardiopulmonary evaluation included assessment of New York Heart Association (NYHA) functional class, left ventricular ejection fraction, peak oxygen uptake, and the distance covered during a standardised six minute walk test. Quality of life significantly decreased with NYHA functional class (linear trend: p < 0.0001). In NYHA class III, the scores of five of the eight quality of life domains were reduced to around one third of those in the general population. The pattern of reduction was different in patients with chronic hepatitis C and major depression, and similar in patients on chronic haemodialysis. Multiple regression analysis showed that only the NYHA functional class was consistently and closely associated with all quality of life scales. The six minute walk test and peak oxygen uptake added to the explanation of the variance in only one of the eight quality of life domains (physical functioning). Left ventricular ejection fraction, duration of disease, and age showed no clear association with quality of life. In congestive heart failure, quality of life decreases as NYHA functional class worsens. Though NYHA functional class was the most dominant predictor among the somatic variables studied, the major determinants of reduced quality of life remain unknown.

    Objective To examine whether baseline chronic stress, morning cortisol, and other appetite-related hormones (leptin, ghrelin, and insulin) predict future weight gain and food cravings in a naturalistic longitudinal 6-month follow-up study. Methods A prospective community cohort of three hundred and thirty-nine adults (age=29.1± 9.0 years; BMI=26.7±5.4 kg/m2; 56.9% female; 70.2% White) completed assessments at baseline and 6-month follow-up. Fasting blood draws were used to assess cortisol and other appetite-related hormones levels at baseline. At baseline and follow-up, body weight was measured and the Cumulative Adversity Interview and Food Craving Inventory were administered. Data were analyzed using linear mixed models adjusting for demographic and clinical covariates. Results Over the 6-month period, 49.9% of the sample gained weight. Food cravings and chronic stress decreased over 6 months (psfood cravings at 6 months (p=0.04). Furthermore, higher cortisol, insulin, and chronic stress were each predictive of greater future weight gain (psfood cravings and reward-driven eating behaviors. Studies are needed that examine the utility of stress reduction methods for normalizing disrupted cortisol responses and preventing future weight gain. PMID:28349668

    Physical activity (PA) and exercise are often used as tools to reduce stress and therefore the risk for developing cardiovascular diseases (CVD). Meanwhile, heart rate variability (HRV) has been utilized to assess both stress and PA or exercise influences. The objective of the present review was to examine the current literature in regards to workplace stress, PA/exercise and HRV to encourage further studies. We considered original articles from known databases (PubMed, ISI Web of Knowledge) over the last 10 years that examined these important factors. A total of seven studies were identified with workplace stress strongly associated with reduced HRV in workers. Longitudinal workplace PA interventions may provide a means to improve worker stress levels and potentially cardiovascular risk with mechanisms still to be clarified. Future studies are recommended to identify the impact of PA, exercise, and fitness on stress levels and HRV in workers and their subsequent influence on cardiovascular health.

    Full Text Available The aim of the present study was to evaluate the influence of age and genetics in dairy heifers on resistance to the cattle tick Rhipicephalus (Boophilus microplus and correlate these parameters with weight gain. Twenty-two heifers were evaluated from birth up to two years of age. Resistance to the cattle tick was evaluated by counting the number of engorged female ticks and subjective qualification of the larvae and nymph infestation. The animals were weighted in the first 24 hours after birth and at six, 12, 18 and 24 months of age. The average tick count and weight gain were compared by Tukey’s test at 5% significance. Subsequently, linear regression was performed to verify the strength of the association between the risk factors age and genetics and infestation by R. (B. microplus. Age and genetics were both significant risk factors for R. (B. microplus infestation in heifers. Between the third and sixth months of age, the animals showed a window of susceptibility to R. (B. microplus. Regardless of age, Bos taurus heifers had higher infestations than Bos indicus, crossbred F1 (½ B. taurus x ½ B. indicus and crossbred Gir-Holstein (Girolando (? B. taurus x ?

    [Purpose] The purpose of this study was to examine the relationship between the paraspinal muscle cross-sectional area and the relative proprioceptive weighting ratio during local vibratory stimulation of older persons with lumbar spondylosis in an upright position. [Subjects] In all, 74 older persons hospitalized for lumbar spondylosis were included. [Methods] We measured the relative proprioceptive weighting ratio of postural sway using a Wii board while vibratory stimulations of 30, 60, or 240 Hz were applied to the subjects' paraspinal or gastrocnemius muscles. Back strength, abdominal muscle strength, and erector spinae muscle (L1/L2, L4/L5) and lumbar multifidus (L1/L2, L4/L5) cross-sectional areas were evaluated. [Results] The erector spinae muscle (L1/L2) cross-sectional area was associated with the relative proprioceptive weighting ratio during 60Hz stimulation. [Conclusion] These findings show that the relative proprioceptive weighting ratio compared to the erector spinae muscle (L1/L2) cross-sectional area under 60Hz proprioceptive stimulation might be a good indicator of trunk proprioceptive sensitivity.

    Full Text Available Abstract Background It is believed that hereditary hemochromatosis (HH might play a role in cardiac disease (heart failure (HF and ischemia. Mutations within several genes are HH-associated, the most common being the HFE gene. In a large cohort of HF patients, we sought to determine the etiological role and the prognostic significance of HFE genotypes. Methods We studied 667 HF patients (72.7% men with depressed systolic function, enrolled in a multicentre trial with a follow-up period of up to 5 years. All were genotyped for the known HFE variants C282Y, H63D and S65C. Results The genotype and allele frequencies in the HF group were similar to the frequencies determined in the general Danish population. In multivariable analysis mortality was not predicted by C282Y-carrier status (HR 1.2, 95% CI: 0.8-1.7; H63D-carrier status (HR 1.0, 95% CI: 0.7-1.3; nor S65C-carrier status (HR 1.2, 95% CI: 0.7-2.0. We identified 27 (4.1% homozygous or compound heterozygous carriers of HFE variants. None of these carriers had a clinical presentation suggesting hemochromatosis, but hemoglobin and ferritin levels were higher than in the rest of the cohort. Furthermore, a trend towards reduced mortality was seen in this group in univariate analyses (HR 0.4, 95% CI: 0.2-0.9, p = 0.03, but not in multivariate (HR 0.5, 95% CI: 0.2-1.2. Conclusion HFE genotypes do not seem to be a significant contributor to the etiology of heart failure in Denmark. HFE variants do not affect mortality in HF.

    Full Text Available Introduction: In spite of its importance as an experimental model, the information on the left coronary artery in pigs is sparse. Objective: To determine the morphologic features of the left coronary artery in pigs. Methods: We evaluated 158 pig hearts. The left coronary artery was perfused with synthetic resin after their ostia had been catheterized. Diameters and courses of the vascular beds were measured with an electronic caliper (Mitutoyo(r. Results: The diameter of left coronary artery was 6.98 ± 1.56 mm and its length was 3.51±0.99 mm. It was found to end up by bifurcating itself into the anterior interventricular artery and the circumflex artery in 79% of the cases, and by trifurcating in 21% of the cases, with the presence of the diagonal artery. The anterior interventricular artery ended up at the apex in 79.7% of the cases, and the circumflex artery at the posterior aspect of the left ventricle in 64% of the case, this artery never reached the posterior interventricular sulcus. An anastomosis between the terminal branches of the anterior interventricular artery and the posterior interventricular artery was found in 7.6% of the specimens. The antero-superior branch of the anterior interventricular artery occurred in 89.9% of the hearts. A left marginal branch was observed in 87.9% of the cases with a diameter of 2.25±0.55 mm. Conclusion: Compared with humans, pigs have shorter left coronary artery trunks and branches; even the circumflex artery never reaches the posterior interventricular sulcus. Our findings are useful for the design of experimental hemodynamic and procedural models.

    Objectives Childhood disadvantage has been associated with increased risk of obesity from childhood through adulthood and those who are disadvantaged across the lifecourse are at highest risk. The effect of lifecourse socioeconomic status (SES) is particularly important for black women due to the higher prevalence of low SES and obesity in black compared to white women. We assessed associations of lifecourse SES, as indicated by educational status, with adult weight in African American women. Design We assessed the associations of parental education, current education (education of participant or her spouse), and a combination of parental and current education (lifecourse education) with weight gain among 21,457 women aged less than age 55 in the longitudinal Black Women’s Health Study which began in 1995. Main Outcome Measures We estimated the mean difference in weight gain between age 18 and age in 2009, and risk ratios for obesity in 2009, in each level of education compared to the highest level (college graduate). Results The age- and height-adjusted differences in mean weight gain for the lowest levels of parental and current education compared to the highest levels were 3.29 and 4.49 kg, respectively. The age-adjusted risk ratios for obesity for the lowest level of parental and current education were 1.44 (95% CI 1.32-1.57) and 1.75 (95% CI 1.57-1.95), respectively. Risk of obesity for was lowest among those with current education of college graduate, regardless of parental education. Conclusions Educational level of college graduate may overcome the adverse effects of low parental education on weight gain and obesity risk. PMID:22764643

    The aim of the study was to investigate the impact of a number of surgical interventions for a various congenital cardiac defects (CHDs) on self-reported HRQoL. Patients who had received corrective surgery of several congenital heart defects (surgical VSD closure, Fallot, TGA after atrial or arterial switch or Fontan-type circulation for univentricular AV-connection) were interviewed in the office of their home peadiatric cardiologist. HRQoL in children along 7 dimensions was assessed using a standardised questionnaire (PEDQoL); information on the medical case history of each respondent was also collected. HRQoL was assessed in the questionnaire by asking about the frequency (never, rarely, often, always) of specific negative experiences; more frequent experiences indicate a lower quality of life. Frequency expressions were transformed into numerical values (25, 50, 75, 100%), and mean values for HRQoL were calculated for each patient and for each domain. Differences in HRQoL among patients with different types of interventions were analysed using the Mann-Whitney Test or the Kruskal-Wallis Test as appropriate; p values <0.05 were considered to indicate significant differences, while p values <0.1 were considered to indicate notable trends. Patients: 169 patients (60% male, 40% female) were part of the study. The mean age was 11.6 years; 50 patients had surgical VSD closure, 52 surgeries for Tetralogy of Fallot (22 transannular patch, 18 no transannular patch, 12 inaccurate description), 40 had complete transposition of the great arteries (28 atrial switch, 12 arterial switch), 22 had a Fontan-type procedure for univentricular AV-connection. HRQoL differed little among patients with different CHDs for the items "relation to friends," "interactions in the affected families", and "own body image". For other items, notable differences emerged: patients with univentricular hearts rated their physical capacity worse and showed a tendency towards negative ratings in

    Prevention of body dissatisfaction development is critical for minimizing adverse effects of poor body esteem on eating behaviors, self-esteem, and overall health. Research has examined body esteem and its correlates largely in pre-adolescents and adolescents; however, important questions remain about factors influencing body esteem of younger children. The main purpose of this study was to test moderation by children's gender and weight status of the relation of maternal controlling feeding practices to 1st graders' body esteem. The Body Esteem Scale (BES) and anthropometric measurements were completed during one-on-one child interviews at school. Mothers completed the Child Feeding Questionnaire (restriction, monitoring, concern, self-assessed maternal weight). A total of 410 mother/child dyads (202 girls) participated. Percent of children classified as overweight (BMI-for-age ≥85th) was: girls - 29%; boys - 27%. Gender moderated the relation between restriction and body esteem (β = -.140, p = .05), with maternal restriction predicting body esteem in girls but not boys. The hypothesized three-way interaction among gender, child weight status, and monitoring was confirmed. Monitoring was significantly inversely related to body esteem only for overweight/obese girls (b = -1.630). The moderating influence of gender or gender and weight status on the link between maternal feeding practices and body esteem suggests the importance of body esteem interventions for girls as early as first grade.

    Venous thromboembolism is a major contributor to the morbidity and mortality of patients with cancer. For patients undergoing cancer surgery, several trials support the safety and efficacy of unfractionated heparin and of low-molecular-weight heparin for the prevention of venous thromboembolism, while data regarding the efficacy and safety of these agents in the setting of medical hospitalization is less definitive and must be extracted from trials including noncancer patients with different thrombotic risk factors. Randomized clinical studies confirm that patients with cancer who develop venous thromboembolism have superior outcomes when treated with long-term low-molecular-weight heparin as compared with warfarin. Novel anticoagulants that are orally bioavailable and function by directly inhibiting factor Xa or thrombin are entering the market. To date, data regarding the efficacy and safety of these novel anticoagulants as venous thromboembolism prophylaxis and treatment in cancer patients are not available and must be extracted from larger trials with heterogeneous patient populations.

    The aim of the current study was to examine whether weight loss self-efficacy, binge eating, and depressive symptoms predicted weight loss during treatment, and whether gender moderates these associations with prospective data from 297 participants (223 women and 74 men) enrolled in a residential obesity treatment program. Men reported higher initial levels of self-efficacy than women, whereas women reported greater pre-treatment levels of binge eating and depressive symptoms. Higher pre-treatment levels of weight control self-efficacy, binge eating, and depressive symptoms predicted greater weight loss in men, but not in women. Results suggest that certain psychological and behavioral factors should be considered when implementing weight loss interventions, and indicate a need to consider gender differences in predictors of weight loss treatment. Future research should seek to identify predictors of weight loss among women.

    To determine the association between weight and the risk of injury in motor vehicle crashes (MVCs) for children 1 through 8 years of age who were using child restraints. This was a cross-sectional study of children 1 to 8 years of age in MVCs, in which cases from the National Automotive Sampling System Crashworthiness Data System were used. Abbreviated Injury Scale scores of ≥2 indicated clinically significant injuries. The National Automotive Sampling System Crashworthiness Data System study sample included 650 children 1 to 5 years of age in forward-facing child restraints who weighed 20 to 65 lb and 344 children 3 to 8 years of age in belt-positioning booster seats who weighed 30 to 100 lb. With adjustment for seating position, type of vehicle, direction of impact, crash severity, and vehicle model year, there was no association between absolute weight and clinically significant injuries in either age group (odds ratio: 1.17 [95% confidence interval: 0.96-1.42] for children 1-5 years of age in forward-facing child restraints and 1.22 [95% confidence interval: 0.96-1.55] for children 3-8 years of age in belt-positioning booster seats). The risk of clinically significant injuries was not associated with weight across a broad weight range in this sample of children in MVCs who were using child restraint systems. Parents should continue to restrain their children according to current recommendations from the American Academy of Pediatrics and the National Highway Traffic Safety Administration.

    Clinical practice shows that thiazolidinediones (TZDs) induce weight gain in patients with type-II diabetes mellitus during treatment, which restrains its application and generalization clinically. It has been demonstrated that acupuncture therapy is useful in easing obesity in clinical trials. In the present paper, we summarize the underlying mechanism of weight gain induced by TZDs through food intake-related targets in the central nervous system and analyze the possible effects of acupuncture therapy. Acupuncture therapy is expected to reduce weight gain side effect of TZDs through 1) lowering permeability of blood brain barrier to reduce TZDs concentration in the brain, 2) upregulating the expression of hypothalamic leptin and inhibiting hypothalamic neuropiptide Y expression, and 3) down-regulating activities of peroxisome proliferator-activated receptor to reduce energy intake and fat syntheses.

  5. The Evidence for Saturated Fat and for Sugar Related to Coronary Heart Disease.

    Dietary guidelines continue to recommend restricting intake of saturated fats. This recommendation follows largely from the observation that saturated fats can raise levels of total serum cholesterol (TC), thereby putatively increasing the risk of atherosclerotic coronary heart disease (CHD). However, TC is only modestly associated with CHD, and more important than the total level of cholesterol in the blood may be the number and size of low-density lipoprotein (LDL) particles that contain it. As for saturated fats, these fats are a diverse class of compounds; different fats may have different effects on LDL and on broader CHD risk based on the specific saturated fatty acids (SFAs) they contain. Importantly, though, people eat foods, not isolated fatty acids. Some food sources of SFAs may pose no risk for CHD or possibly even be protective. Advice to reduce saturated fat in the diet without regard to nuances about LDL, SFAs, or dietary sources could actually increase people's risk of CHD. When saturated fats are replaced with refined carbohydrates, and specifically with added sugars (like sucrose or high fructose corn syrup), the end result is not favorable for heart health. Such replacement leads to changes in LDL, high-density lipoprotein (HDL), and triglycerides that may increase the risk of CHD. Additionally, diets high in sugar may induce many other abnormalities associated with elevated CHD risk, including elevated levels of glucose, insulin, and uric acid, impaired glucose tolerance, insulin and leptin resistance, non-alcoholic fatty liver disease, and altered platelet function. A diet high in added sugars has been found to cause a 3-fold increased risk of death due to cardiovascular disease, but sugars, like saturated fats, are a diverse class of compounds. The monosaccharide, fructose, and fructose-containing sweeteners (e.g., sucrose) produce greater degrees of metabolic abnormalities than does glucose (either isolated as a monomer, or in chains as starch

    The use of high fructose corn syrup (HFCS) has increased over the past several decades in the United States while overweight and obesity rates have risen dramatically. Some scientists hypothesize that HFCS consumption has uniquely contributed to the increasing mean body mass index (BMI) of the U.S. population. The Center for Food, Nutrition, and Agriculture Policy convened an expert panel to discuss the published scientific literature examining the relationship between consumption of HFCS or "soft drinks" (proxy for HFCS) and weight gain. The authors conducted original analysis to address certain gaps in the literature. Evidence from ecological studies linking HFCS consumption with rising BMI rates is unreliable. Evidence from epidemiologic studies and randomized controlled trials is inconclusive. Studies analyzing the differences between HFCS and sucrose consumption and their contributions to weight gain do not exist. HFCS and sucrose have similar monosaccharide compositions and sweetness values. The fructose:glucose (F:G) ratio in the U.S. food supply has not appreciably changed since the introduction of HFCS in the 1960s. It is unclear why HFCS would affect satiety or absorption and metabolism of fructose any differently than would sucrose. Based on the currently available evidence, the expert panel concluded that HFCS does not appear to contribute to overweight and obesity any differently than do other energy sources. Research recommendations were made to improve our understanding of the association of HFCS and weight gain.

    Full Text Available Abstract Background Child growth is internationally recognized as an important indicator of nutritional status and health in populations. This study was aimed to compare age- and gender-specific height, weight and BMI percentiles and nutritional status relative to the international growth references among Pakistani school-aged children. Methods A population-based study was conducted with a multistage cluster sample of 1860 children aged five to twelve years in Lahore, Pakistan. Smoothed height, weight and BMI percentile curves were obtained and comparison was made with the World Health Organization 2007 (WHO and United States' Centers for Disease Control and Prevention 2000 (USCDC references. Over- and under-nutrition were defined according to the WHO and USCDC references, and the International Obesity Task Force (IOTF cut-offs. Simple descriptive statistics were used and statistical significance was considered at P Results Height, weight and BMI percentiles increased with age among both boys and girls, and both had approximately the same height and a lower weight and BMI as compared to the WHO and USCDC references. Mean differences from zero for height-, weight- and BMI-for-age z score values relative to the WHO and USCDC references were significant (P Conclusion Pakistani school-aged children significantly differed from the WHO and USCDC references. However, z score means relative to the WHO reference were closer to zero and the present study as compared to the USCDC reference. Overweight and obesity were significantly higher while underweight and thinness/wasting were significantly lower relative to the WHO reference as compared to the USCDC reference and the IOTF cut-offs. New growth charts for Pakistani children based on a nationally representative sample should be developed. Nevertheless, shifting to use of the 2007 WHO child growth reference might have important implications for child health programs and primary care pediatric clinics.

    The research was designed to compare the effect of cadmium and p-nonylphenol on the increase of uterine weight and to study the related mechanisms. It provided basic evidence for us to understand the possible different mechanisms among different EEDs. In this study, both ovaries of 60 Wistar rats (28 days age) were ectomized, and after 21 days recovery, the rats were randomly assigned into six groups and exposed to cadmium (0.12, 1.20 mg/kg), NP (100, 200 mg/kg), control (sterile PBS), and positive control (17β-estradiol) per day for 3 days, respectively, then related indexes were detected. The results showed that the increase of uterine weight induced by cadmium was accompanied by the increase of the thickness of luminal epithelium cell and endometrium but the decrease of nuclear/cytoplasm of luminal epithelium cell and endometrium, while the increase of uterine weight induced by p-nonylphenol was accompanied by the increase of the thickness of luminal epithelium cell, endometrium, and myometrium but the decrease of nuclear/cytoplasm of luminal epithelium cell and endometrium. Cadmium could inhibit the positive expression of PCNA while p-nonylphenol prompted it. Exposure to cadmium and NP both could also stimulate phosphorylation of ERK mitogen-activated protein kinases, implying that this signal pathway had an effect on the increase of the uterine weight induced by cadmium and p-nonylphenol. The results indicate that cadmium may induce the increase of uterine weight, which is accompanied with toxic effect on endometrium, while NP's effect of the increase of uterine weight is due to cell proliferation of endometrium, the mechanisms of which are the same as estrogen, but they may both activate ERK signal pathway

    Full Text Available Previous research has shown that a mindfulness-based decentering technique can help individuals resist eating chocolate over a 5-day period. However, it is unclear how this technique exerts its effect. This study explored one potential mechanism; that decentering increases the cognitive accessibility of relevant goals. Male and female participants (n = 90 spent 5 min practicing either a decentering or relaxation (control technique. They then viewed a picture of a chocolate bar for 3 min whilst either applying the decentering technique or letting their mind wander (control. Finally, all participants completed 20 letter strings, rated their motivation for weight loss and for healthy eating, and indicated whether or not they were dieting to lose weight. As predicted, those who had applied the decentering technique produced a greater number of health and weight loss related words when completing the letter strings, compared to those who had simply let their mind wander (p < 0.001. However, contrary to predictions, these effects were not significantly greater amongst those who were more motivated to lose weight or eat healthily, or amongst those who were dieting to lose weight, though the means were in the predicted directions. The results suggest that this particular mindfulness technique may increase the accessibility of relevant goals. Further research would be needed to (a compare effects with other strategies that prompt individuals to remember their goals, (b examine other potential mechanisms of action, and (c confirm that effects on self-control are mediated by increased goal accessibility.

    BACKGROUND: Metabolic syndrome (MS) is associated with subsequent development of type 2 diabetes and cardiovascular disease in the general population. The impact of MS on mortality in patients with stable coronary heart disease is less well defined, and the association of prognosis to gender...... follow-up of 9.2 years. RESULTS: At follow-up 296 (28%) patients had died. 315 (30%) patients had MS based on the definition by the World Health Organization. Patients with MS more frequently had diabetes and three-vessel disease of the coronary arteries. Men had a more severe risk profile than women....... In a multivariable Cox regression analysis, MS was not associated with excess mortality risk in the overall population [adjusted HR=1.3 (95% CI: 0.7-2.3), p=0.43]. In gender specific analyses MS increased risk of all-cause mortality in women [adjusted HR=2.2 (95% CI: 1.1-4.3), p=0.02], but not in men [adjusted HR=1...

    To investigate the contribution of genetic polymorphisms of vitamin K epoxide reductase complex subunit 1 gene VKORC1-1639G>A, cytochrome P450 2C9 gene (CYP2C9), EPHXI, and clinical factors to warfarin sensitivity in southwest Chinese Han patients with mechanical heart valve prostheses. A total of 127 patients with mechanical heart valve prostheses who have been followed up at our department during the past 23 years were enrolled in this study and compared to a control group that consisted of 133 randomly selected healthy blood donors. These Chinese patients met stable warfarin dosage requirements and had reached the target international normalized ratio (INR) of 1.5-2.0. PCR and direct sequencing were carried out to identify the polymorphisms of VKORC1-1639G>A (rs9923231), CYP2C9*3 (rs1057910), CYP2C9 IVS3-65G>C (rs9332127), and EPHX1691A>G (rs4653436). In addition, total and free (non-protein-bound) warfarin concentrations were analyzed. There were great interindividual differences in warfarin maintenance dosage (ranging from 0.6 to 8.4 mg/day) among the 127 patients with mechanical heart valve prostheses. VKORC1-1639G>A, CYP2C9, EPHX1691A>G polymorphism, body weight, and age were found to affect the dose demands. Multiple linear regression models incorporating genetic polymorphisms of VKORC1, CYP2C9, EPHX1691A>G, and the nongenetic factors of age and body weight were developed, and explained up to 76.8% of the total variation (adjusted R (2) of 0.743) in warfarin maintenance doses in southwest Chinese patients with mechanical heart valve prostheses.

    Few studies have used social networking sites to track temporal trends in health-related posts, particularly around weight loss. To examine the temporal relationship of Twitter messages about weight loss over 1 year (2012). Temporal trends in #weightloss mentions and #fitness, #diet, and #health tweets which also had the word "weight" in them were examined using three a priori time periods: (1) holidays: pre-winter holidays, holidays, and post-holidays; (2) Season: winter and summer; and (3) New Year's: pre-New Year's and post-New Year's. Regarding #weightloss, there were 145 (95 % CI 79, 211) more posts/day during holidays and 143 (95 % CI 76, 209) more posts/day after holidays as compared to 480 pre-holiday posts/day; 232 (95 % CI 178, 286) more posts/day during the winter versus summer (441 posts/day); there was no difference in posts around New Year's. Examining social networks for trends in health-related posts may aid in timing interventions when individuals are more likely to be discussing weight loss.

    The aim of this study was to evaluate the impact of a workplace-based weight loss program (Workplace POWER [Preventing Obesity Without Eating like a Rabbit]) for male shift workers on a number of work-related outcomes. A total of 110 overweight/obese (body mass index = 25-40) (mean [SD] age = 44.3 [8.6] years; body mass index = 30.5 [3.6]) male employees at Tomago Aluminium (New South Wales, Australia) were randomized to either (i) Workplace POWER program (n = 65) or (ii) a 14-week wait-list control group (n = 45). Men were assessed at baseline and 14-week follow-up for weight, quality of life, sleepiness, productivity at work (presenteeism), absenteeism, and workplace injuries. Retention was 81%. Intention-to-treat analysis using linear mixed models revealed a significant intervention effect for weight, quality of life (mental), presenteeism, absenteeism, and injuries. The Workplace POWER weight loss program improved a number of important work-related outcomes in male shift workers.

    Over the last decades, a decline in motor skills and in physical activity and an increase in obesity has been observed in children. However, there is a lack of data in young children. We tested if differences in motor skills and in physical activity according to weight or gender were already present in 2- to 4-year-old children. Fifty-eight child care centers in the French part of Switzerland were randomly selected for the Youp'là bouge study. Motor skills were assessed by an obstacle course including 5 motor skills, derived from the Zurich Neuromotor Assessment test. Physical activity was measured with accelerometers (GT1M, Actigraph, Florida, USA) using age-adapted cut-offs. Weight status was assessed using the International Obesity Task Force criteria (healthy weight vs overweight) for body mass index (BMI). Of the 529 children (49% girls, 3.4 ± 0.6 years, BMI 16.2 ± 1.2 kg/m2), 13% were overweight. There were no significant weight status-related differences in the single skills of the obstacle course, but there was a trend (p = 0.059) for a lower performance of overweight children in the overall motor skills score. No significant weight status-related differences in child care-based physical activity were observed. No gender-related differences were found in the overall motor skills score, but boys performed better than girls in 2 of the 5 motor skills (p ≤ 0.04). Total physical activity as well as time spent in moderate-vigorous and in vigorous activity during child care were 12-25% higher and sedentary activity 5% lower in boys compared to girls (all p physical activity was higher in boys compared to girls. These results are important to consider when establishing physical activity recommendations or targeting health promotion interventions in young children.

    Leptin is a peptidic hormone secreted by the fat tissue and plays an important role in body weight regulation. After menopause, weight gain increases as well as android-like obesity. Previous studies suggest a relationship between leptin level, body mass index (BMI) and fat distribution. To establish the relationships between serum leptin, BMI, waist circumference (WC), and waist/hip ratio (WHR). 48 women under the age of 60 years and with amenorrhea for longer than one year were assessed. Leptin and estradiol (ELISA) levels were determined; normal values: 3.63-11.09 ng/mL and 0-65 pg/Ml. BMI (WHO), WC > 88 cm, and WHR > 0.80 were considered as indicators of cardiometabolic risk. Mean age for the group was 54 +/- 3.9 years; leptin: 8.4 +/- 3.7 ng/mL, and estradiol: 17.6 +/- 10.0 pg/mL; BMI: 27.0 +/- 4.9 kg/m(2); WC: 86.2 +/- 8.6 cm; and WHR: 0.84 +/- 0.06. Twenty percent of the women had hyperleptinemia, 58.4% malnourishment due to excessive intake, 35% presented WC cardiovascular risk. The highest leptin value was found in obese women. There was no association between serum leptin levels and anthropometrical variables. There was a significantly positive correlation between weight, height, BMI, WC, hip circumference, and estradiol. Postmenopausal women presented a high prevalence of overweight/obesity, android-like body fat distribution and normal serum leptin levels. The group assessed is considered to be at risk for cardiometabolic diseases according to anthropometrical indicators.

    Weight suppression (WS), which is the difference between a patient's highest and current weight, has been associated with bulimic symptom severity in adults with bulimia nervosa (BN). However, the impact of WS on eating disorder psychopathology in youth with BN is unknown. Participants included 85 youth with DSM-5 BN who presented for outpatient treatment. Current WS was calculated as the difference between highest and current body mass index z-score (BMIz), while greatest WS was the difference between highest and lowest BMIz, both assessed at participants' current height. Separate multivariable linear regressions were conducted to determine if current or greatest WS was significantly associated with frequency of binge eating, compensatory behaviors, or dietary restraint. A secondary analysis was conducted on youth ages 16 and older, given the limitation of assessing WS at current height in younger participants with greater height instability. Youth with higher levels of greatest WS (but not current WS) were older, had a longer duration of illness, and reported greater weight and shape concern. When adjusting for BMIz, neither current nor greatest WS was significantly associated with bulimic behaviors or dietary restraint in the full sample. However, in the subset of youth ages 16 and older, current WS moderated the effect of BMIz on binge eating and compensatory behaviors. For youth with high WS, those with a high current BMIz engaged in more frequent binge eating than those with low current BMIz, and the negative impact of BMIz on compensatory behaviors became weaker. Our findings suggest that WS is clinically relevant in the presentation of youth with BN, and that it may need to be addressed as one important factor in BN psychopathology. Future studies using growth charts to determine historically highest and lowest BMIz may help to further elucidate the link (or lack thereof) between WS and BN psychopathology in youth.

    To analyze the relationship between route of delivery and other aspects of pregnancy and the occurrence of intracranial hemorrhage in newborns of very low weight at a teaching hospital in South Brazil. A case-control study was conducted. Medical records of all patients who were born weighing ≤ 1,500 g and who were submitted to transfontanellar ultrasonography were analyzed from January 2011 to September 2014. The cases were newborns with diagnosis of intracranial hemorrhage, while newborns with regular exams were used as controls. Differences between groups were analyzed by the Student t test and by χ2 or Fisher exact tests, and association was determined using the odds ratio with a 95% confidence interval and α = 5%. A total of 222 newborns with birth weight ≤ 1,500 g were recorded; of these, 113 were submitted to transfontanellar ultrasonography and were included in the study. Sixty-nine (61.1%) newborns were diagnosed with intracranial hemorrhage (cases) and 44 (38.9%) showed no abnormal results (controls). Most cases had grade I hemorrhage (96.8%) originating from the germinative matrix (95.7%). The predominant route of delivery was caesarean section (81.2% of the cases and 72.7% of the controls). Five deaths were recorded (3 cases and 2 controls). Gestational age ranged from 24 to 37 weeks. Median birth weight was 1,205 g (range: 675-1,500 g). The median time of hospitalization was 52 days, ranging from 5 to 163 days. Grade I intracranial hemorrhage from the germinative matrix was the most frequent. No differences were found between cases and controls for the variables studied. The small number of infants submitted to transfontanellar ultrasonography limited the sample size and the results of the study.

    This cross-sectional study was aimed at determining whether certain pre-natal and natal conditions can predict specific dental anomalies. The conditions observed were: low birth-weight, preterm birth, pre-natal & natal complications. The dental anomalies observed were: enamel defects, total number of decayed, missing and filled teeth (total DMFT), disturbances in the tooth shape and disturbances in the number of teeth. Out of more than 2000 medical files of children aged 2-17 years old which were reviewed, 300 files met the selection criteria. Information recorded from the files included: age, gender, health status (the ASA physical status classification system by the American Society of Anesthesiologists), birth week, birth weight, total DMFT, hypomineralization, abnormal tooth shape, abnormal number of teeth and hypoplasia. Twenty one children out of 300 (7%) were born after a high-risk pregnancy, 25 children (8.3%) were born after high-risk birth, 20 children (6.7%) were born preterm - before week 37, and 29 children (9.7%) were born with a low birth weight (LBW) - 2500 grams or less. A relationship between a preterm birth and LBW to hypomineralization was found. And a relationship between a preterm birth and high-risk pregnancy to abnormal number of teeth was found. No relationship was found between birth (normal/high-risk) and the other parameters inspected. Preterm birth and LBW may predict hypomineralization in both primary and permanent dentitions. Furthermore, the study demonstrated that preterm birth and high-risk pregnancy may predict abnormal number of teeth in both dentitions.

    Full Text Available Mechanoelectric feedback (MEF is the process by which mechanical forces on the myocardium can alter its electrical properties. The effect can be large enough to induce ectopic beats or fibrillation. However, the role of MEF at physiological levels of mechanical stress is not clear. We have investigated alteration in action potential morphology in rat and guinea pig ventricle and in rat atrial tissue at levels of stretch near the plateau of the Frank-Starling curve. Stretch of >100 mm.Hg End Diastolic Left Ventricular Pressure (EDLVP or rapidly applied stretch (EDLVP increased by 25 mm.Hg within 100 ms often triggered ectopic beats in isolated rat and guinea-pig hearts. However, ventricular epicardial monophasic action potentials (MAPs recorded during stretch to EDLVP up to 30 mm. Hg showed no consistent changes in action potential duration (at APD20, APD50 or APD80 in either species. MAP recording detected APD prolongation with very small concentrations of 4-AP (10 μM, confirming the discrimination of the recording technique. In isolated rat atrial strips, no changes in intracellular action potential morphology or membrane potential were seen when stretched to levels producing an optimum increase in contractility. We conclude that alteration in action potential morphology with stretch does not contribute to the Frank-Starling relation in ventricle of rat or guinea-pig isolated heart, or in rat atrial tissue.

    Since 1978, we have witnessed a successful evolution of assisted reproductive technology (ART), with improvement of the pregnancy rates and a growing demand. However, in recent years, there has been increasing concern regarding its safety due to the potential health impact on its infants. The raise of the developmental origins of adult disease has positioned low birth weight (LBW) as a significant health issue. Despite multiple studies have associated ART with LBW, the etiology of this association remains largely unknown. This paper reviews the potential association between different components of ART and infertility with LBW, while acknowledging the limitations to interpretation of the existing literature.

    Low physical fitness and obesity have been associated with higher risk of developing heart failure (HF), but their interactive effects are unknown. Elucidation of interactions among these common modifiable factors may help facilitate more effective primary prevention. We conducted a national cohort study to examine the interactive effects of aerobic fitness, muscular strength and body mass index (BMI) among 1 330 610 military conscripts in Sweden during 1969-1997 (97%-98% of all 18-year-old men) on risk of HF identified from inpatient and outpatient diagnoses through 2012 (maximum age 62 years). There were 11 711 men diagnosed with HF in 37.8 million person-years of follow-up. Low aerobic fitness, low muscular strength and obesity were independently associated with higher risk of HF, after adjusting for each other, socioeconomic factors, other chronic diseases and family history of HF. The combination of low aerobic fitness and low muscular strength (lowest vs highest tertiles) was associated with a 1.7-fold risk of HF (95% CI 1.6 to 1.9; pfitness, low muscular strength and obesity at the age of 18 years were independently associated with higher risk of HF in adulthood, with interactive effects between aerobic fitness and muscular strength. These findings suggest that early-life interventions may help reduce the long-term risk of HF and should include both aerobic fitness and muscular strength, even among persons with normal BMI. © Article author(s) (or their employer(s) unless otherwise stated in the text of the article) 2017.

    To compare the frequency of beta thalassaemia trait in individuals with Ischaemic Heart Disease (IHD) and a control population without IHD. Study Design: Case control study. Place and Duration of Study: Department of Haematology, Armed Forces Institute of Pathology (AFIP), Rawalpindi, from September 2007 to May 2009. Methodology: Using non-probability consecutive sampling, a total of 544 subjects were selected, including 272 IHD patients and an equal number of age and gender matched normal controls. The subjects were tested for the presence of b-thalassaemia trait by performing their blood counts, haemoglobin electrophoresis and Haemoglobin A2 (HbA2) estimation. Proportions were compared using chi-square test. Odds ratio was also calculated. Results: The frequency of b-thalassaemia trait was determined in IHD patients and was compared to the frequency in normal Pakistani population. Six out of the 272 control subjects (2.2%) had b-thalassaemia trait and one of the control subject had Haemoglobin D trait. In contrast, none of the 272 IHD patients had b-thalassaemia trait. The calculated odds ratio was less than 1, which shows a significant negative association of b-thalassaemia trait with IHD. The difference in the frequency of b-thalassaemia trait in the two groups was statistically significant (p=0.033). Conclusion: The results suggest that b-thalassaemia carriers have some protection against IHD, though it is not an absolute cardio protection due to the role of other risk factors in IHD. This beneficial information may be communicated to the concerned individuals in their counselling sessions and as part of general awareness on thalassaemia. (author)

The study was carried out between May and June 2004. The population of the study consisted of seventeen thousands students attending their formal education in Atatürk University Campus. It was determined that the number of the students including in the study was 1250, but the participation rate in the study was 89.6% (1120 person. With simple randomized method, which classroom of each faculty would be included in the sampling was determined. All the students in determined classroom were included in the study content. Percent of the male students were 60.6 % and single students were 96.6% . Mean age of students were 21.6 ± 1.9 year, average body mass index (BMI value was 21.9 ± 2.7 kg/m2. The prevalence of overweight and obesity were higher in the male students, and the thinness were higher in female students. It was found out that there was no statistically significant distinction in terms of BMI values averages according to their making regular sport, using alcohol and smoking and taking nutrition education. There was significant correlation between BMI score and monthly personal income.

    Full Text Available Limited data exist regarding the association between binge eating and quality of life (QOL in obese adolescent girls and boys. We, therefore, studied binge eating and QOL in 158 obese (BMI ≥ 95th percentile adolescents (14.5 ± 1.4 years, 68.0% female, 59% African-American prior to weight-loss treatment. Youth completed an interview to assess binge eating and a questionnaire measure of QOL. Controlling for body composition, binge eating youth (n = 35, overall, reported poorer QOL in domains of health, mobility, and self-esteem compared to those without binge eating ( ps < 0.05. Also, girls, overall, reported poorer QOL than boys in activities of daily-living, mobility, self-esteem, and social/interpersonal functioning (ps < 0.05. Girls with binge eating reported the greatest impairments in activities of daily living, mobility, self-esteem, social/interpersonal functioning, and work/school QOL (ps < 0.05. Among treatment-seeking obese adolescents, binge eating appears to be a marker of QOL impairment, especially among girls. Prospective and treatment designs are needed to explore the directional relationship between binge eating and QOL and their impact on weight outcomes.

    Objectives: To investigate the imaging findings of immunoglobulin G4 (IgG4)-related kidney disease (IgG4-KD) on magnetic resonance imaging (MRI) including diffusion-weighted imaging (DWI) and to evaluate the usefulness of DWI in lesion detection. Methods: This retrospective cohort study included 31 patients with IgG4-KD who underwent MRI covering both kidneys. Two radiologists reviewed in consensus the MR images to determine the distribution pattern (location, laterality, and multiplicity) and the visually assessed signal intensity (hypointense, isointense or hyperintense) of the renal lesions compared to the normal renal parenchyma on each sequence. Per-patient sensitivity for detecting IgG4-KD and the number of detectable lesions were compared in T2-weighted images, DWI, and dynamic contrast-enhanced images. Results: IgG4-KD typically manifested as bilateral (83.9%), multiple (93.5%), and renal parenchymal (87.1%) nodules appearing isointense (93.5%) on T1-weighted images, hypointense (77.4%) on T2-weighted images, hyperintense (100%) on DWI (b = 1000), and hypointense (83.3%) in the arterial phase and with a progressive enhancement pattern on dynamic contrast-enhanced images. The sensitivity of DWI for detecting IgG4-KD was significantly higher than that of T2-weighted images (100% vs. 77.4%, P = 0.034). The median number of detectable lesions was significantly greater in DWI (n = 9) than in T2-weighted images (n = 2) and dynamic contrast-enhanced images (n = 5) (P ≤ 0.008). Conclusions: The characteristic MRI findings of IgG4-KD were bilateral, multiple, renal parenchymal nodules with T2 hypointensity, diffusion restriction, and a progressive enhancement pattern. As DWI was useful in the detection of IgG4-KD, adding DWI to conventional MRI for patients suspected of having IgG4-KD may enhance the diagnosis.

    To explore changes in illness perception and health-related quality of life in patients with coronary heart disease following percutaneous coronary intervention from the time when patients were discharged from hospital and five months later and to investigate association between illness perception and physical and mental health-related quality of life at five-month follow-up. Illness perception is known to influence patients' motivation to engage in preventive behaviour. Prospective and comparative with two measurement points: at discharge from hospital (time 1) and five months later (time 2). Two self-administered questionnaires were used as follows: the Illness Perception Questionnaire-Revised measured illness perception and the Short Form Health Survey (SF-36) measured physical and mental health-related quality of life. The sample consisted of patients with coronary heart disease admitted to University Hospital between November 2011-April 2012. A total of 69 questionnaires were returned for both measurement times. Most responders were male (71%), mean age was 68·9 (SD 10·3) years. Health-related quality of life increased over time, and illness perception changed; five months after discharge, participants were more aware that the disease was chronic and could worsen suddenly, and they perceived that the disease had less of a consequence on their lives compared to when they were staying in the hospital. Associations between increased personal control, changeability of the disease, perceptions of less of a consequence of the disease on daily life and increased health-related quality of life were demonstrated at time 2. Perceptions of personal control, changeability and consequences of the disease should be assessed and discussed with cardiac patients, as these illness perceptions are related to physical and mental health-related quality of life. Increased understanding of consequences of the disease, personal control and perceived changeability of the illness

    To examine whether baseline chronic stress, morning cortisol, and other appetite-related hormones (leptin, ghrelin, and insulin) predict future weight gain and food cravings in a naturalistic, longitudinal, 6-month follow-up study. A prospective community cohort of 339 adults (age 29.1 ± 9.0 years; BMI = 26.7 ± 5.4 kg/m 2 ; 56.9% female; 70.2% white) completed assessments at baseline and 6-month follow-up. Fasting blood draws were used to assess cortisol and other appetite-related hormone levels at baseline. At baseline and follow-up, body weight was measured, and the Cumulative Adversity Interview and Food Craving Inventory were administered. Data were analyzed using linear mixed models adjusting for demographic and clinical covariates. Over the 6-month period, 49.9% of the sample gained weight. Food cravings and chronic stress decreased over 6 months (Ps < 0.05). However, after adjusting for covariates, individuals with higher baseline total ghrelin had significantly higher food cravings at 6 months (P = 0.04). Furthermore, higher cortisol, insulin, and chronic stress were each predictive of greater future weight gain (Ps < 0.05). These results suggest that ghrelin plays a role in increased food cravings and reward-driven eating behaviors. Studies are needed that examine the utility of stress reduction methods for normalizing disrupted cortisol responses and preventing future weight gain. © 2017 The Obesity Society.

    Full Text Available Parrotfishes (family Labridae: Scarini are regarded to have important roles for maintaining the ecosystem balance in coral reefs due to their removal of organic matter and calcic substrates by grazing. The purpose of the present study was to clarify the interspecific differences in grazing ability of five parrotfish species (Chlorurus sordidus, C. bowersi, Scarus rivulatus, S. niger and S. forsteni in relation to interspecific differences in jaw-lever mechanics and the relative weight of the adductor mandibulae (muscles operating jaw closing. The grazing ability was calculated by using stomach contents (CaCO3 weight/organic matter weight defined as the grazing ability index (GAI. There were significant interspecific differences in GAI (C. sordidus = C. bowersi > S. rivulatus > S. niger = S. forsteni. Teeth of C. sordidus and C. bowersi were protrusive-shape whereas teeth of S. rivulatus, S. niger and S. forsteni were flat-shape. C. sordidus and C. bowersihave jaw-lever mechanics producing a greater biting force and have a larger weight of adductor mandibulae. S. rivulatus has jaw-lever mechanics producing a greater biting force but a smaller weight of adductor mandibulae that produce an intermediate biting force. In contrast, S. niger and S. forsteni have jaw-lever mechanics producing a lesser biting force and have a smaller weight of adductor mandibulae. Feeding rates and foray size of S. rivulatus, S. niger and S. forsteni were greater than C. sordidus and C. bowersi. The degree in bioerosion (GAI × feeding rate was the largest for S. rivulatusand the smallest for S. forsteni. The degree in bioerosion for C. sordidus was larger than S. niger whereas relatively equal between C. bowersi and S. niger. These results suggest that interspecific difference in GAI was explained by interspecific differences in teeth shape, jaw-lever mechanics and relative weight of adductor mandibulae. The interspecific difference in the degree of bioerosion suggests

    Full Text Available Abstract Background Over the last decades, a decline in motor skills and in physical activity and an increase in obesity has been observed in children. However, there is a lack of data in young children. We tested if differences in motor skills and in physical activity according to weight or gender were already present in 2- to 4-year-old children. Methods Fifty-eight child care centers in the French part of Switzerland were randomly selected for the Youp'là bouge study. Motor skills were assessed by an obstacle course including 5 motor skills, derived from the Zurich Neuromotor Assessment test. Physical activity was measured with accelerometers (GT1M, Actigraph, Florida, USA using age-adapted cut-offs. Weight status was assessed using the International Obesity Task Force criteria (healthy weight vs overweight for body mass index (BMI. Results Of the 529 children (49% girls, 3.4 ± 0.6 years, BMI 16.2 ± 1.2 kg/m2, 13% were overweight. There were no significant weight status-related differences in the single skills of the obstacle course, but there was a trend (p = 0.059 for a lower performance of overweight children in the overall motor skills score. No significant weight status-related differences in child care-based physical activity were observed. No gender-related differences were found in the overall motor skills score, but boys performed better than girls in 2 of the 5 motor skills (p ≤ 0.04. Total physical activity as well as time spent in moderate-vigorous and in vigorous activity during child care were 12-25% higher and sedentary activity 5% lower in boys compared to girls (all p Conclusions At this early age, there were no significant weight status- or gender-related differences in global motor skills. However, in accordance to data in older children, child care-based physical activity was higher in boys compared to girls. These results are important to consider when establishing physical activity recommendations or targeting

    Full Text Available The needs for support among children with a seriously ill parent, who is waiting for heart transplantation, are unknown today. The aim was to describe now adult children’s experiences of social support in relation to a parent’s heart transplant during childhood. Nine females and four males were interviewed. The median age for the children was 18 at the transplantation and their parents had been ill before for 18 months (median and on waiting list for 161 days (mean. Three categories emerged: health care professionals’ approaches, family and friends’ approaches, and society approaches. Our results show that there was lack of support for children of heart transplantation patients. Support in the shape of information was in most cases provided by the sick or healthy parent. It is of great clinical importance to develop psychosocial support programs for children with a seriously ill parent waiting for heart transplantation (before, during, and after surgery.

    BACKGROUND: Studies suggest that gestational weight gain (GWG) and breastfeeding behavior may influence long-term maternal abdominal fat mass. However, this could be confounded by abdominal fat mass before pregnancy because it is unknown whether abdominal fat mass, independently of body size......, affects GWG and breastfeeding behavior. OBJECTIVE: We investigated how maternal prepregnancy fat distribution, described by waist circumference (WC) and body mass index (BMI), is associated with GWG and breastfeeding behavior. DESIGN: We analyzed 1371 live births to 1024 women after enrollment...... in the Coronary Artery Risk Development in Young Adults study (1985-1996). For each birth, maternal prepregnancy BMI and WC were measured at year 0 (baseline), 2, 5, or 7 examinations. Recalled GWG and breastfeeding behavior were collected at years 7 and 10. GWG was analyzed by using linear regression...

    This study aimed to provide an overview of lifestyle changes after breast cancer diagnosis and to examine the relationship between dietary and physical activity changes with weight changes in breast cancer patients. Women with breast carcinomas (n=368) were recruited from eight hospitals and four breast cancer support groups in peninsular Malaysia. Dietary and physical activity changes were measured from a year preceding breast cancer diagnosis to study entry. Mean duration since diagnosis was 4.86±3.46 years. Dietary changes showed that majority of the respondents had decreased their intake of high fat foods (18.8-65.5%), added fat foods (28.3-48.9%), low fat foods (46.8-80.7%), red meat (39.7%), pork and poultry (20.1-39.7%) and high sugar foods (42.1-60.9%) but increased their intake of fish (42.7%), fruits and vegetables (62.8%) and whole grains (28.5%). Intake of other food groups remained unchanged. Only a small percentage of the women (22.6%) had increased their physical activity since diagnosis where most of them (16.0%) had increased recreational activities. Age at diagnosis (β= -0.20, p= 0.001), and change in whole grain (β= -0.15, p= 0.003) and fish intakes (β= 0.13, p= 0.013) were associated with weight changes after breast cancer diagnosis. In summary, the majority of the women with breast cancer had changed their diets to a healthier one. However, many did not increase their physical activity levels which could improve their health and lower risk of breast cancer recurrence.

    Aims: Inhibition of neprilysin, an enzyme degrading natriuretic and other vasoactive peptides, is beneficial in heart failure with reduced ejection fraction (HFrEF), as shown in PARADIGM-HF which compared the angiotensin receptor–neprilysin inhibitor (ARNI) sacubitril/valsartan with enalapril....... As neprilysin is also one of many enzymes clearing amyloid-β peptides from the brain, there is a theoretical concern about the long-term effects of sacubitril/valsartan on cognition. Therefore, we have examined dementia-related adverse effects (AEs) in PARADIGM-HF and placed these findings in the context...... of other recently conducted HFrEF trials. Methods and results: In PARADIGM-HF, patients with symptomatic HFrEF were randomized to sacubitril/valsartan 97/103 mg b.i.d. or enalapril 10 mg b.i.d. in a 1:1 ratio. We systematically searched AE reports, coded using the Medical Dictionary for Regulatory...

    The present study investigated anxiety-related emotional reasoning in 9-13-year-old children using an experimental approach. Eighty-one children completed a computerized ambiguous situations test for assessing their perception of threat under two conditions. In the experimental condition, children were attached to an apparatus that allegedly recorded their heart beat, the sound of which was presented to them via headphones. In the control condition, children listened to the sound of an African djembe drum while completing the ambiguous situations test. It was found that children in the experimental condition generally provided higher threat ratings than children in the control condition, and this difference remained significant when controlling for levels of anxiety sensitivity, panic and other anxiety symptoms. These results are in keeping with the idea that children may partially rely on internal physical sensations when evaluating the dangerousness of ambiguous events. (c) 2010 Elsevier Ltd.

    Adipocyte size is a major modulator of endocrine functioning of adipose tissue and methods allowing accurate determination of adipocyte size are important to study energy metabolism. The aim of this study was to assess the relative shrinkage of adipocytes before and after weight loss by comparing adipose tissue from the same subjects embedded in paraffin and plastic. 18 healthy subjects (5 males and 13 females) aged 20-50 y with a BMI of 28-38 kg/m² followed a very low energy diet for 8 weeks. Adipose tissue biopsies were taken prior to and after weight loss and were processed for paraffin and plastic sections. Parameters of adipocyte size were determined with computer image analysis. Mean adipocyte size was smaller in paraffin compared to plastic embedded tissue both before (66 ± 4 vs. 103 ± 5 μm, P paraffin embedded tissue in proportion to plastic embedded tissue was not significantly different before and after weight loss (73 and 69%, respectively). Shrinkage due to the type of embedding of the adipose tissue can be ignored when comparing before and after weight loss. Plastic embedding of adipose tissue provides more accurate and sensitive results. © 2013 Asian Oceanian Association for the Study of Obesity . Published by Elsevier Ltd. All rights reserved.

    To investigate the associations of major depressive disorder with coronary heart disease (CHD) and stroke in Chinese adults aged 30-79 years. In 2004-2008, China Kadoorie Biobank was conducted in 10 geographically defined regions (5 urban and 5 rural) of China. A total number of 512 891 participants aged 30-79 years were recruited in the baseline survey. A laptop-based electronic questionnaire was administrated face-to-face by trained health workers, collecting the general demographic and socio-economic status, dietary and other lifestyle behaviours (e.g. smoking, alcohol drinking, physical activity), medical history and family history of common chronic diseases. Major depressive episodes (MDE) in the past 12 months were assessed with the World Health Organization composite international diagnostic interview-short form (CIDI-SF). The physical measurements included the heights and weights, which were used to calculate the body mass indexes (BMI).Chi squared and t test were used to compare the differences in participants characteristics according to their major depressive disorder. Logistic models were employed to estimate the odds ratios (OR) and 95% CI of their major depressive disorder with prevalent coronary heart disease and stroke. Among the 512 891 participants, 3 281 (0.6%) showed an MDE in the preceding 12 months, 15 472 (3.0%) reported prevalent CHD, and 8 884 (1.7%) reported prevalent stroke. Major depressive disorder was significantly associated with an increased risk of CHD and risk of stroke. Age- and gender-adjusted ORs (95% CI) were 1.80 (1.53-2.12) for CHD and 2.53 (2.09-3.05) for stroke. The associations were significant after further adjustment for potential confounders, such as other socio-demographic status, smoking, alcohol drinking, physical activity, and BMI, prevalent hypertension, diabetes as well as family history of cardiovascular diseases (OR=1.83, 95% CI=1.54-2.18 for CHD; OR=2.19, 95% CI=1.79-2.69 for stroke). Moreover, gender

    and at follow-up about 5 years later were analyzed with multiple linear regression and dietary macronutrient substitution models. Interactions between dietary protein and baseline body mass index (BMI) and baseline WC adjusted for BMI (WCBMI ) (divided in tertiles; nine groups total), were analyzed in relation...... protein, whether replacing carbohydrate or fat, and weight change. However, individuals in the highest tertile of baseline BMI (irrespective of baseline WCBMI ) had significantly inverse change in waist circumference when protein replaced carbohydrate, but not when protein replaced fat. CONCLUSION......: Replacing carbohydrate with protein in the diet may prevent a relative increase in WC in individuals with a greater BMI....

    In this study, male and female participants were exposed to identical news stories covering obesity topics paired with tweets from Twitter users. Our study aimed at understanding how obesity-related news combined with user-generated social media posts (i.e., tweets) affect consumers' evaluations of online content and viral behavioral intentions (the intentions to like, share, and comment). An experiment (N = 316) explored how gender and weight of a Twitter user (tweeter) affect participants' evaluations and viral behavioral intentions toward news stories. Participants differed in their evaluations of and viral behavioral intentions for news stories as a function of Twitter users' gender and weight, as well as participants' gender. While participants expressed more favorable attitudes toward news stories paired with tweets by overweight than healthy females (with the opposite true for tweets by male users), participants expressed greater viral behavioral intentions for news stories paired with tweets by healthy weight than overweight user. These effects were more pronounced among male than female participants. Findings are discussed within the context of social media posts and their persuasive effects in relation to attitude and behavior changes.

    T2-weighted fast spin-echo imaging (T2-W FSE) is frequently degraded by motion in pediatric patients. MR imaging with periodically rotated overlapping parallel lines with enhanced reconstruction (PROPELLER) employs alternate sampling of k-space to achieve motion reduction. To compare T2-W PROPELLER FSE (T2-W PROP) with conventional T2-W FSE for: (1) image quality; (2) presence of artefacts; and (3) ability to detect lesions. Ninety-five pediatric patients undergoing brain MRI (1.5 T) were evaluated with T2-W FSE and T2-W PROP. Three independent radiologists rated T2-W FSE and T2-W PROP, assessing image quality, presence of artefacts, and diagnostic confidence. Chi-square analysis and Wilcoxon signed rank test were used to assess the radiologists' responses. Compared with T2-W FSE, T2-W PROP demonstrated better image quality and reduced motion artefacts, with the greatest benefit in children younger than 6 months. Although detection rates were comparable for the two sequences, blood products were more conspicuous on T2-W FSE. Diagnostic confidence was higher using T2-W PROP in children younger than 6 months. Average inter-rater agreement was 87%. T2-W PROP showed reduced motion artefacts and improved diagnostic confidence in children younger than 6 months. Thus, use of T2-W PROP rather than T2-W FSE should be considered in routine imaging of this age group, with caution required in identifying blood products. (orig.)

    Full Text Available Purpose. To identify whether non-overweight students were different from their overweight or obese peers with respect to diet, suboptimal meal behaviours, and physical activity using a self-administered web-based survey. Methods. 4097 adolescents living in Alberta, Canada completed Web-SPAN (Web Survey of Physical Activity and Nutrition. Students were classified as overweight or obese, and differences were described in terms of nutrient intakes, physical activity, and meal behaviours. Results. Non-overweight students consumed significantly more carbohydrate and fibre, and significantly less fat and high calorie beverages, and had a higher frequency of consuming breakfast and snacks compared to overweight or obese students. Both non-overweight and overweight students were significantly more active than obese students. Conclusions. This research supports the need to target suboptimal behaviours such as high calorie beverage consumption, fat intake, breakfast skipping, and physical inactivity. School nutrition policies and mandatory physical education for all students may help to improve weight status in adolescents.

    Planning an action primes feature dimensions that are relevant for that particular action, increasing the impact of these dimensions on perceptual processing. Here, we investigated whether action planning also affects the short-term maintenance of visual information. In a combined memory and movement task, participants were to memorize items defined by size or color while preparing either a grasping or a pointing movement. Whereas size is a relevant feature dimension for grasping, color can be used to localize the goal object and guide a pointing movement. The results showed that memory for items defined by size was better during the preparation of a grasping movement than during the preparation of a pointing movement. Conversely, memory for color tended to be better when a pointing movement rather than a grasping movement was being planned. This pattern was not only observed when the memory task was embedded within the preparation period of the movement, but also when the movement to be performed was only indicated during the retention interval of the memory task. These findings reveal that a weighting of information in visual working memory according to action relevance can even be implemented at the representational level during maintenance, demonstrating that our actions continue to influence visual processing beyond the perceptual stage.

    Full Text Available Taeyeumjoweetang (TYJWT is a herbal medication that was mentioned in Jema Lee's Donguisusebowon, which is a book about Sasang constitutional medicine. Tae-eumnis, one of the four constitutions, tend to suffer from metabolic diseases such as obesity and diabetes. It is widely used to treat the digestive problems and obesity of Tae-eumins. We divided mice that were fed a normal diet for 48 days into control, TYJWT 250 mg kg-1 and TYJWT 500 mg kg-1 groups. After carrying out the experiments, the serum levels of leptin, adiponectin, ghrelin and resistin were measured. The results showed that TYJWT significantly reduced the weights of mice that were fed a normal diet, and that this was due to a decrease in food intake. Also, the two TYJWT groups had lower serum levels of leptin compared to the control group, and the ghrelin levels were proportionately increased by the dosage of TYJWT given. These results show that TYJWT has obesity-suppressing effects similar to those previously reported using high fat diets. In addition, these results also provide evidence that TYJWT has anti-obesity effects.
