Methods: A secondary analysis of a randomized clinical trial consisting of a SBT with either fat-restricted standard or lacto-ovo vegetarian diet. The 12-month intervention was delivered in 33 group sessions. The first six months reflected the intensive phase; the second six months, the less-intensive intervention phase. We conducted the analysis without regard to treatment assignment. Eligible participants included overweight/obese adults (N = 176; mean body mass index = 34.0 kg/m2. The sample was 86.9% female, 70.5% White, and 44.4 ± 8.6 years old. The outcome measures included weight and biomarkers. Results: There was a significant decline in adherence to each treatment component over time (P < 0.0001. In the first six months, adherence to attendance, self-monitoring and the energy goal were significantly associated with greater weight loss (P < 0.05. Adherence to attendance and exercise remained significantly associated with weight loss in the second six months (P < 0.05. Adherence to attendance, self-monitoring and exercise had indirect effects through weight loss on LDL, triglycerides, and insulin (P < 0.05.Conclusions: We observed a decline in adherence to each

    Community health centers (CHCs) seek effective strategies to address obesity. MidWest Clinicians' Network partnered with [an academic medical center] to test feasibility of a weight management quality improvement (QI) collaborative. MidWest Clinicians' Network members expressed interest in an obesity QI program. This pilot study aimed to determine whether the QI model can be feasibly implemented with limited resources at CHCs to improve weight management programs. Five health centers with weight management programs enrolled with CHC staff as primary study participants; this study did not attempt to measure patient outcomes. Participants attended learning sessions and monthly conference calls to build QI skills and share best practices. Tailored coaching addressed local needs. Topics rated most valuable were patient recruitment/retention strategies, QI techniques, evidence-based weight management, motivational interviewing. Challenges included garnering provider support, high staff turnover, and difficulty tracking patient-level data. This paper reports practical lessons about implementing a weight management QI collaborative in CHCs.

    The present study examined the effectiveness of the Kid's Choice Program (KCP) for increasing children's weight management behaviors, and decreasing body mass index percentile (BMI%) for overweight and average-weight children. It also evaluated KCP characteristics relevant to long-term application in schools. Participants included 382 children assigned to two groups: a KCP group that received token rewards for three "Good Health Behaviors" including eating fruits or vegetables first at meals (FVFIRST), choosing low-fat and low-sugar healthy drinks (HDRINK), and showing 5000 exercise steps recorded on pedometers (EXERCISE), or a control group that received token rewards for three "Good Citizenship Behaviors." School lunch observations and pedometer records were completed for one month under baseline and three months under reward conditions. The school nurse calculated children's BMI% one year before baseline, at baseline, at the end of KCP application, and six months later. The KCP increased FVFIRST, HDRINK, and EXERCISE from baseline through reward conditions, with ANCOVAs demonstrating that these increases were associated with both the offer of reward and nearby peer models. Overweight (n=112) and average-weight (n=200) children showed drops in BMI% after the three-month KCP, but overweight children re-gained weight six months later, suggesting the need for more ongoing KCP application. HDRINK choice was the behavior most associated with BMI% drops for overweight children. Small teams of parent volunteers effectively delivered the KCP, and school staff endorsed parent volunteers as the best personnel to deliver the KCP, which costs approximately two U.S. dollars per child per month of application.

    Emerging adults ages 18-25 are at high risk for obesity, but are markedly underrepresented in behavioural weight loss (BWL) programs and experience lower engagement and retention relative to older adults. To utilize a mixed methods approach to inform future efforts to effectively recruit and engage this high-risk population in BWL programs. We used a convergent parallel design in which quantitative and qualitative data were given equal priority. Study 1 (N = 137, age = 21.8 + 2.2, BMI = 30.1 + 4.7) was a quantitative survey, conducted online to reduce known barriers and minimize bias. Study 2 (N = 7 groups, age = 22.3 + 2.2, BMI = 31.5 + 4.6) was a qualitative study, consisting of in person focus groups to gain greater depth and identify contextual factors unable to be captured in Study 1. Weight loss was of interest, but weight itself was not a central motivation; an emphasis on overall lifestyle, self-improvement and fitness emerged as driving factors. Key barriers were time, motivation and money. Recruitment processes should be primarily online with messages tailored specifically to motivations and preferences of this age group. Preferences for a program were reduced intensity and brief, hybrid format with some in-person contact, individual level coaching, experiential learning and peer support. Key methods of promoting engagement and retention were autonomy and choice, money and creating an optimal default. An individually tailored lifestyle intervention that addresses a spectrum of health behaviours, promotes autonomy and emphasizes activity and fitness may facilitate recruitment and engagement in this population better than traditional BWL protocols.

    The purposes of this study were to compare postural stability between obese and lean subjects and to investigate the effect of a 3-week body weight reduction (BWR) program entailing specific balance training on postural stability of extremely obese patients. Time of balance maintenance and mean error on the medial-lateral direction at the trunk and lower limb level were assessed during a single limb stance on a movable platform in 19 non-obese and in 20 extremely obese individuals (age range: 20-40 yr). Time of balance maintenance was shorter (obese: 21.1+/-7.7 vs lean: 27.3+/-3.1 sec) and medial-lateral sway of the trunk was larger in obese (5.4+/-3.2 degrees) than in lean (3.2+/-1.1 degrees) subjects (pprogram (energy-restricted diet, moderate physical exercise, nutritional education and psychological counselling) combined with or without 6 sessions of specific balance training on a movable platform. BWR plus specific balance training enhanced time of balance maintenance (pre: 23.8+/-7.2 vs post: 30.0+/-0.0 sec) and reduced the trunk sway (5.2+/-2.8 degrees vs 2.6+/-0.9 degrees ) more than BWR alone (pprogram. It was concluded that balance improvement is an important goal of rehabilitation, that would probably reduce the propensity of overweight individuals to fall while performing everyday activities.

    African American women have higher prevalence (82%) of overweight (body mass index [BMI] 25?29) and obesity (BMI ?30) than white women (63.2%) or Hispanic women (77.2%), and weight-loss programs yield minimal results in this population. We examine the concept of BMI as a measure of health for African American women and suggests a more holistic, multifaceted approach to preventing chronic disease.

Among those who are obese, HRQL is often lower than the general population and even more when considering obesity-related comorbidities and bodily pain. The objectives of this paper were to determine the impact of a multidisciplinary, community-based obesity reduction program on HRQL and to determine the independent risk factors for lack of improvement from baseline to follow-up. HRQL was measured using the Medical Outcomes Study 36-Item Short-Form Health Survey (SF-36 at baseline and follow-up (24 weeks. To date, 84.5% of those who completed the program had improvements in their overall SF-36 score. Significant increases in the mean scores on eight dimensions of health were also observed. Lack of improvement was independently affected by smoking status (odds ratio 3.75; 95% confidence interval 1.44–9.78; P=0.007 and not having a buddy to attend the program (odds ratio 3.70; 95% confidence interval 1.28–10.68; P=0.015. Obesity reduction programs that target increasing exercise, improving diet, and cognitive behavioral therapy can positively impact HRQL in obese adults. Social support has a strong role to play in improving outcomes. Keywords: obesity, health-related quality of life, social- support, SF-36, Canada

    Behavioral weight-loss treatments have been overwhelmingly unsuccessful. Many inadequately address both behavioral theory and extant research--especially in regard to the lack of viability of simply educating individuals on improved eating and exercise behaviors. The aim was to synthesize research on associations of changes in exercise behaviors, psychosocial factors, eating behaviors, and weight; and then conduct further direct testing to inform the development of an improved treatment approach. A systematic program of health behavior-change research based on social cognitive theory, and extensions of that theory applied to exercise and weight loss, was first reviewed. Then, to extend this research toward treatment development and application, a field-based study of obese adults was conducted. Treatments incorporated a consistent component of cognitive-behaviorally supported exercise during 26 weeks that was paired with either standard nutrition education (n = 183) or cognitive-behavioral methods for controlled eating that emphasized self-regulatory methods such as goal setting and caloric tracking, cognitive restructuring, and eating cue awareness (n = 247). Both treatment conditions were associated with improved self-efficacy, self-regulation, mood, exercise, fruit and vegetable consumption, weight, and waist circumference; with improvements in self-regulation for eating, fruit and vegetable consumption, weight, and waist circumference significantly greater in the cognitive-behavioral nutrition condition. Changes in exercise- and eating-related self-efficacy and self-regulation were associated with changes in exercise and eating (R(2) = 0.40 and 0.17, respectively), with mood change increasing the explanatory power to R(2) = 0.43 and 0.20. Improved self-efficacy and self-regulation for exercise carried over to self-efficacy and self-regulation for controlled eating (β= 0.53 and 0.68, respectively).

    Childhood obesity and related health consequences continue to be major clinical and public health issues in the United States. Schools provide an opportunity to implement obesity prevention strategies to large and diverse pediatric audiences. Healthier Options for Public Schoolchildren was a quasiexperimental elementary school-based obesity prevention intervention targeting ethnically diverse 6- to 13-year-olds (kindergarten through sixth grade). Over 2 school years (August 2004 to June 2006), five elementary schools (four intervention, one control, N=2,494, 48% Hispanic) in Osceola County, FL, participated in the study. Intervention components included integrated and replicable nutrition, physical activity, and lifestyle educational curricula matched to state curricula standards; modified school meals, including nutrient-dense items, created by registered dietitians; and parent and staff educational components. Demographic, anthropometric, and blood pressure data were collected at baseline and at three time points over 2 years. Repeated measures analysis showed significantly decreased diastolic blood pressure in girls in the intervention group compared to controls (P<0.05). Systolic blood pressure decreased significantly for girls in the intervention group compared to controls during Year 1 (fall 2004 to fall 2005) (P<0.05); while not statistically significant the second year, the trend continued through Year 2. Overall weight z scores and body mass index z scores decreased significantly for girls in the intervention group compared to controls (P<0.05 and P<0.01, respectively). School-based prevention interventions, including nutrition and physical activity components, show promise in improving health, particularly among girls. If healthy weight and blood pressure can be maintained from an early age, cardiovascular disease in early adulthood may be prevented. Copyright 2010 American Dietetic Association.

    Greater use of key self-regulatory behaviors (e.g., self-monitoring of food intake and weight) is associated with greater weight loss within behavioral weight loss treatments, although this association is less established within widely-available commercial weight loss programs. Further, high hedonic hunger (i.e., susceptibility to environmental food cues) may present a barrier to successful behavior change and weight loss, although this has not yet been examined. Adult men and women (N=111, body mass index M±SD=31.5±2.7kg/m(2)) were assessed before and after participating in a 12-week commercial weight loss program. From pre- to post-treatment, reported usage of weight control behaviors improved and hedonic hunger decreased, and these changes were inversely associated. A decrease in hedonic hunger was associated with better weight loss. An improvement in reported weight control behaviors (e.g., self-regulatory behaviors) was associated with better weight loss, and this association was even stronger among individuals with high baseline hedonic hunger. Findings highlight the importance of specific self-regulatory behaviors within weight loss treatment, including a commercial weight loss program developed for widespread community implementation. Assessment of weight control behavioral skills usage and hedonic hunger may be useful to further identify mediators of weight loss within commercial weight loss programs. Future interventions might specifically target high hedonic hunger and prospectively examine changes in hedonic hunger during other types of weight loss treatment to inform its potential impact on sustained behavior change and weight control.

    Explanatory evaluation of interventions for prevention of weight gain is required beyond changes in weight, to determine for whom the intervention works and the underlying mechanisms of change. It was hypothesised that participant characteristics moderate intervention effect on weight change and improved eating and physical activity behaviours during the 3-month program mediate the relationship between intervention and weight. In our randomised controlled trial, young adults at risk of weight gain (n = 250) were assigned either to an intervention group that received a 3-month mHealth (TXT2BFiT) program with 6-month maintenance or to a control group. Data were collected via online self-report surveys. Hypothesised moderators and mediators of the intervention effect on weight were independently assessed in PROCESS macro models for 3 and 9-month weight change. Males (P = 0.01), mid-20s age group (P = 0.04), and higher income earners (P = 0.02) moderated intervention effects on weight change at 3-months and males only at 9-months (P = 0.02). Weight change at 3 (-1.12 kg) and 9-months (-1.38 kg) remained significant when 3-month nutrition and physical activity behaviours were specified as mediators (P <0.01 and P = 0.01 respectively). Indirect paths explained 39% (0.72/1.85 kg) and 40 % (0.92/2.3 kg) of total effect on weight change at 3 and 9-months respectively. Increased vegetable intake by intervention group at 3-months accounted for 19 and 17% and decreased sugar-sweetened beverages accounted for 8 and 13% of indirect weight change effects at 3 and 9-months respectively. TXT2BFiT was effective for both young men and women. Small sustained behavioural changes, including increased vegetable intake and decreased sugar-sweetened beverages consumption significantly mediated the intervention's effects on weight change. Improved eating behaviours and increased physical activity accounted for approximately 40% of the weight change. The trial is

    We propose an improved reference speaker weighting (RSW) and speaker cluster weighting (SCW) approach that uses an aspect model. The concept of the approach is that the adapted model is a linear combination of a few latent reference models obtained from a set of reference speakers. The aspect model has specific latent-space characteristics that differ from orthogonal basis vectors of eigenvoice. The aspect model is a “mixture-of-mixture” model. We first calculate a small number of latent reference models as mixtures of distributions of the reference speaker's models, and then the latent reference models are mixed to obtain the adapted distribution. The mixture weights are calculated based on the expectation maximization (EM) algorithm. We use the obtained mixture weights for interpolating mean parameters of the distributions. Both training and adaptation are performed based on likelihood maximization with respect to the training and adaptation data, respectively. We conduct a continuous speech recognition experiment using a Korean database (KAIST-TRADE). The results are compared to those of a conventional MAP, MLLR, RSW, eigenvoice and SCW. Absolute word accuracy improvement of 2.06 point was achieved using the proposed method, even though we use only 0.3 s of adaptation data.

    Successfully addressing childhood onset obesity requires multilevel (individual, community, and governmental), multi-agency collaboration. The Healthier Options for Public Schoolchildren (HOPS)/OrganWise Guys (OWG) quasi-experimental controlled pilot study (four intervention schools, one control school, total N=3,769; 50.2% Hispanic) was an elementary school-based obesity prevention intervention designed to keep children at a normal, healthy weight, and improve health status and academic achievement. The HOPS/OWG included the following replicable, holistic components: (1) modified dietary offerings, (2) nutrition/lifestyle educational curricula; (3) physical activity component; and (4) wellness projects. Demographic, anthropometric (body mass index [BMI]), blood pressure, and academic data were collected during the two-year study period (2004-6). Statistically significant improvements in BMI, blood pressure, and academic scores, among low-income Hispanic and White children in particular, were seen in the intervention versus controls. Holistic school-based obesity prevention interventions can improve health outcomes and academic performance, in particular among high-risk populations.

    Background Online weight loss programs are increasingly popular. However, little is known about outcomes and associations with website usage among members of free online weight loss programs. Objective This retrospective cohort study examined the association between website usage and weight loss among members of a free commercial online weight loss program (SparkPeople). Methods We conducted a retrospective analysis of a systematic random sample of members who joined the program during February 1 to April 30, 2008, and included follow-up data through May 10, 2010. The main outcome was net weight change based on self-reported weight. Measures of website usage included log-ins, self-monitoring entries (weight, food, exercise), and use of social support tools (discussion forums, friendships). Results The main sample included 1258 members with at least 2 weight entries. They were 90.7% female, with mean (SD) age 33.6 (11.0) and mean (SD) BMI 31.6 (7.7). Members with at least one forum post lost an additional 1.55 kg (95% CI 0.55 kg to 2.55 kg) relative to those with no forum posts. Having at least 4 log-in days, weight entry days, or food entry days per 30 days was significantly associated with weight loss. In the multiple regression analysis, members with at least 4 weight entry days per 30 days reported 5.09 kg (95% CI 3.29 kg to 6.88 kg) more weight loss per 30 days than those with fewer weight entry days. After controlling for weight entry days, the other website usage variables were not associated with weight change. Conclusions Weekly or more frequent self-monitoring of weight is associated with greater weight loss among members of this free online weight loss program. PMID:23322819

    Studies have shown an association between nut consumption and health benefits in adults such as lower lipid levels, lower body mass indices, and reduced risk of coronary artery disease. Few studies have demonstrated these health benefits in children. To determine the association between peanut consumption and weight, intake of nutrients of concern, high-density lipoprotein, low-density lipoprotein, and cholesterol in Mexican American children, baseline data from 262 sixth-grade students (48% female) in a school-based weight management program were analyzed to compare differences between peanut and non-peanut eaters. It was hypothesized that Mexican American children who consume peanuts will be less overweight and have a better nutrient and lipid profile when compared to those who do not eat peanuts. Participants completed a food frequency questionnaire as a baseline dietary assessment before beginning the program. Children were identified as either a peanut consumer (n = 100) or non-peanut consumer (n = 162). Body mass index measurements were taken on all participants. A smaller sample of participants submitted blood for lipid analysis. Analyses revealed that children in the peanut consumer group were less likely to be overweight or obese than children in the non-peanut consumer group (χ(2) = 13.9, P = .001), had significantly higher intakes of several vitamins and micronutrients (i.e., magnesium, vitamin E), and had lower low-density lipoprotein and total cholesterol levels. These results illustrate that consumption of peanuts and/or peanut butter is associated with lower weight status, improved diet, and lipid levels among Mexican American children. Future research is needed to clarify the role of peanut consumption in children's overall health. Copyright © 2013 Elsevier Inc. All rights reserved.

Participants were 75 enrollees into an employer-sponsored weight loss program who reported high levels of overeating in response to thoughts and feelings. Seventy-five overweight and obese participants (92% female, 65% Caucasian, aged 26 to 68 years) were randomized to the new mindfulness weight loss program (n = 50) or the standard behavioral weight loss program (n = 25). Both programs consisted of 11 coaching calls with health coaches and registered dietitians with supplemental online materials. Satisfaction, engagement, and percent weight lost did not significantly differ for intervention vs. control at six months. Intervention participants had significantly better scores at six-month follow-up on mindful eating, binge eating, experiential avoidance, and one mindfulness subscale. Exploratory analyses showed that improvements on several measures predicted more weight loss in the intervention group. This pilot study found that integrating mindfulness into a brief phone-based behavioral weight loss program was feasible and acceptable to participants, but did not produce greater weight loss on average, despite hypothesized changes in mindful eating. Only one third of intervention participants reported participating in mindfulness exercises regularly. Mechanisms of change observed within the intervention group suggest that for adults with high levels of emotional eating those who embrace mindful eating and meditation may lose more weight with a mindfulness intervention.

    To examine the effect of duration and frequency of exercise on weight loss and cardiorespiratory fitness in previously sedentary, overweight, women. Randomized, controlled, 4-arm trial of 12-months duration. A university-based behavioral weight loss program during the years 2000 and 2001. Eligibility criteria were: women, 21 to 45 years of age, body mass index (BMI) 27 to 40, reporting exercise exercise or that would affect metabolism or weight loss, being treated for psychologic conditions, pregnant, recently pregnant, or planning pregnancy, having a medical condition that could affect metabolism or body weight (eg, diabetes) or that would limit exercise participation. All 201 participants were assigned to a standard behavioral weight loss program, which included regular group meetings and telephone calls, and caloric and dietary fat restrictions. Participants were given meal plans and kept weekly food diaries. The women were assigned to 1 of 4 exercise groups based on energy expenditure of 1000 kcal/wk or 2000 kcal/wk and exercise intensity (moderate versus vigorous). Exercise intensity was prescribed according to percentage of age-predicted maximal heart rate and rating of perceived exertion. Energy expenditure was converted to minutes of exercise per week. The groups were vigorous intensity/high duration, moderate intensity/high duration, moderate intensity/moderate duration, and vigorous intensity/moderate duration. All 4 groups started the program at moderate intensity and moderate duration (100 min/week of walking) and increased the vigor and duration of exercise to set targets of 200, 300, 200, and 150 min/week, for the groups respectively. Treadmills were provided to the participants, and feedback on their weekly exercise logs was given. At 6 and 12 months, changes in body weight and BMI were measured. Cardiorespiratory fitness was measured by a graded exercise treadmill test and expressed as percent change in oxygen consumption from baseline. Excluding 5

    To explore which baseline physiological and psychosocial variables predict change in body mass index (BMI) z-score in obese youth after 12 weeks of a dietary weight management study. Participants were obese young people participating in a dietary intervention trial in Brisbane Australia. The outcome variable was change in BMI z-score. Potential predictors considered included demographic, physiological and psychosocial parameters of the young person, and demographic characteristics of their parents. A multivariable regression model was constructed to examine the effect of potential predictive variables. Participants (n = 88) were predominantly female (69.3%), and had a mean(standard deviation) age of 13.1(1.9) years and BMI z-score of 2.2(0.4) on presentation. Lower BMI z-score (p resistance (p = 0.04) at baseline, referral from a paediatrician (p = 0.02) and being more socially advantaged (p = 0.046) were significantly associated with weight loss. Macronutrient distribution of diet and physical activity level did not contribute. Early intervention in obesity treatment in young people improves likelihood of success. Other factors such as degree of insulin resistance, social advantage and referral source also appear to play a role. Assessing presenting characteristics and factors associated with treatment outcome may allow practicing clinicians to individualise a weight management program or determine the 'best-fit' treatment for an obese adolescent. © 2013 Asian Oceanian Association for the Study of Obesity .

    Study Objective: To investigate the influence of sleep disordered breathing (SDB) on weight loss in overweight/obese veterans enrolled in MOVE!, a nationally implemented behavioral weight management program delivered by the National Veterans Health Administration health system. Methods: This observational study evaluated weight loss by SDB status in overweight/obese veterans enrolled in MOVE! from May 2008–February 2012 who had at least two MOVE! visits, baseline weight, and at least one follow-up weight (n = 84,770). SDB was defined by International Classification of Diseases, Ninth Revision, Clinical Modification codes. Primary outcome was weight change (lb) from MOVE! enrollment to 6- and 12-mo assessments. Weight change over time was modeled with repeated-measures analyses. Results: SDB was diagnosed in one-third of the cohort (n = 28,269). At baseline, veterans with SDB weighed 29 [48] lb more than those without SDB (P Weight loss patterns over time were statistically different between veterans with and without SDB (P weight (−2.5 [0.1] lb) compared to those without SDB (−3.3 [0.1] lb; P = 0.001) at 6 months. At 12 mo, veterans with SDB continued to lose weight whereas veterans without SDB started to re-gain weight. Conclusions: Veterans with sleep disordered breathing (SDB) had significantly less weight loss over time than veterans without SDB. SDB should be considered in the development and implementation of weight loss programs due to its high prevalence and negative effect on health.

    Employers are increasingly adopting workplace wellness programs designed to improve employee health and decrease employer costs associated with health insurance and job absenteeism. This paper examines the outcomes of 2635 workers across 24 worksites who were offered financial incentives for weight loss that took various forms, including fixed payments and forfeitable bonds. We document extremely high attrition and modest weight loss associated with the financial incentives in this program, which contrasts with the better outcomes associated with pilot programs. We conclude by offering suggestions, motivated by behavioral economics, for increasing the effectiveness of financial incentives for weight loss. Copyright © 2013 Elsevier B.V. All rights reserved.

    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.

Methods: The study sample included 311 obese patients participating in a weight loss program, which comprised a 12-week weight reduction phase (low-calorie formula diet and a 40-week weight maintenance phase. Body weight and glucose and lipid values were determined at the beginning of the program as well as after the weight reduction and the weight maintenance phase. Participants were analyzed according to their BMI class at baseline (30-34.9 kg/m2; 35-39.9 kg/m2; 40-44.9 kg/m2; 45-49.9 kg/m2; ≥50 kg/m2. Furthermore, moderately obese patients (BMI 2 were compared to severely obese participants (BMI ≥ 40 kg/m2. Results: Out of 311 participants, 217 individuals completed the program. Their mean baseline BMI was 41.8 ± 0.5 kg/m2. Average weight loss was 17.9 ± 0.6%, resulting in a BMI of 34.3 ± 0.4 kg/m2 after 1 year (p Conclusion: 1-year weight loss intervention improves body weight as well as lipid and glucose metabolism not only in moderately, but also in severely obese individuals.

    Few studies have focused on weight loss programs implemented in community-based primary care settings. The objective of this analysis was to evaluate the effectiveness of a weight loss program and determine whether physicians in primary care practices could achieve reductions in body weight and body fat similar to those obtained in weight loss clinics. Analyses were performed on chart review data from 413 obese participants who underwent weight loss at a primary care (n=234) or weight loss (n=179) clinic. Participants received physician-guided behavioral modification sessions and self-selected a diet plan partially or fully supplemented by meal replacements. A repeated-measures analysis of covariance was conducted with age and sex serving as covariates; significance was set at P≤.05. In 178 subjects (43%) completing 12 weeks of the program, primary care clinics were as effective as weight loss clinics at achieving reductions in body weight (12.4 vs 12.1 kg) but better with regard to reduction in body fat percentage (3.8% vs 2.7%; P≤.05). Regardless of location, participants completing 12 weeks lost an average of 11.1% of their body weight. Participants selecting full meal replacement had greater reductions in weight and body fat percentage (12.7 kg, 3.5%) compared with participants selecting a partial meal replacement plan (8.3 kg, 2.3%). Primary care physicians can successfully manage and treat obese patients using behavioral modification techniques coupled with meal replacement diets. Copyright © 2012 Elsevier Inc.

    Full Text Available Background. Weight lost by obese patients is almost always regained over time. Extended treatment may improve maintenance, but solid evidence is lacking. Purpose. We determined effectiveness of maintenance therapy after a weight loss program. Methods. Together 201 patients (mean age 47 years and BMI 42 kg/m2, 71% women were randomly assigned to either a 17-week weight loss program followed by a one-year maintenance program or to a weight loss program without subsequent maintenance intervention. The weight loss program included behavior modification and a very-low-calorie diet, and maintenance program behavior modification. The primary outcome measure was percentage of patients with 5% or more weight loss at the end of maintenance (week 69 and one year later (week 121. Secondary outcomes were weight related changes in lifestyle and quality of life. Results. At week 69, 52% of the patients with and 44% of those without maintenance program had lost weight ≥5%, P=0.40, and, at week 121, 33% and 34%, P=0.77, respectively. At week 121 secondary outcomes did not differ between the groups among those successfully followed up. Conclusions. This one-year maintenance program was not effective in preventing weight regain in severely obese patients. Trial Registration. This trial is registered under clinicaltrials.gov Identifier: NCT00590655.

    Full Text Available This paper gives an evaluation of different ways to increase university admission test criterion-related validity, by differentially weighting test items. We compared four methods of weighting multiple-choice items of the Basic Skills and Knowledge Examination (EXHCOBA: (1 punishing incorrect responses by a constant factor, (2 weighting incorrect responses, considering the levels of error, (3 weighting correct responses, considering the item’s difficulty, based on the Classic Measurement Theory, and (4 weighting correct responses, considering the item’s difficulty, based on the Item Response Theory. Results show that none of these methods increased the instrument’s predictive validity, although they did improve its concurrent validity. It was concluded that it is appropriate to score the test by simply adding up correct responses.

    Daily weighing is emerging as the recommended self-weighing frequency for weight loss. This is likely because it improves adoption of weight control behaviors. To examine whether weighing every day is associated with greater adoption of weight control behaviors compared with less frequent weighing. Longitudinal analysis of a previously conducted 6-month randomized controlled trial. Overweight men and women in Chapel Hill, NC, participated in the intervention arm (N=47). The intervention focused on daily weighing for weight loss using an e-scale that transmitted weights to a study website, along with weekly e-mailed lessons and tailored feedback on daily weighing adherence and weight loss progress. We gathered objective data on self-weighing frequency from the e-scales. At baseline and 6 months, weight change was measured in the clinic and weight control behaviors (total items=37), dietary strategies, and calorie expenditure from physical activity were assessed via questionnaires. Calorie intake was assessed using an online 24-hour recall tool. We used χ(2) tests to examine variation in discrete weight control behaviors and linear regression models to examine differences in weight, dietary strategies, and calorie intake and expenditure by self-weighing frequency. Fifty-one percent of participants weighed every day (n=24) over 6 months. The average self-weighing frequency among those weighing less than daily (n=23) was 5.4±1.2 days per week. Daily weighers lost significantly more weight compared with those weighing less than daily (mean difference=-6.1 kg; 95% CI -10.2 to -2.1; P=0.004). The total number of weight control behaviors adopted was greater among daily weighers (17.6±7.6 vs 11.2±6.4; P=0.004). There were no differences by self-weighing frequency in dietary strategies, calorie intake, or calorie expenditure. Weighing every day led to greater adoption of weight control behaviors and produced greater weight loss compared with weighing most days of the

  20. Fetal Programming of Obesity: Maternal Obesity and Excessive Weight Gain

    2014-10-01

    Full Text Available The prevalence of obesity is an increasing health problem throughout the world. Maternal pre-pregnancy weight, maternal nutrition and maternal weight gain are among the factors that can cause childhood obesity. Both maternal obesity and excessive weight gain increase the risks of excessive fetal weight gain and high birth weight. Rapid weight gain during fetal period leads to changes in the newborn body composition. Specifically, the increase in body fat ratio in the early periods is associated with an increased risk of obesity in the later periods. It was reported that over-nutrition during fetal period could cause excessive food intake during postpartum period as a result of metabolic programming. By influencing the fetal metabolism and tissue development, maternal obesity and excessive weight gain change the amounts of nutrients and metabolites that pass to the fetus, thus causing excessive fetal weight gain which in turn increases the risk of obesity. Fetal over-nutrition and excessive weight gain cause permanent metabolic and physiologic changes in developing organs. While mechanisms that affect these organs are not fully understood, it is thought that the changes may occur as a result of the changes in fetal energy metabolism, appetite control, neuroendocrine functions, adipose tissue mass, epigenetic mechanisms and gene expression. In this review article, the effects of maternal body weight and weight gain on fetal development, newborn birth weight and risk of obesity were evaluated, and additionally potential mechanisms that can explain the effects of fetal over-nutrition on the risk of obesity were investigated [TAF Prev Med Bull 2014; 13(5.000: 427-434

    Forty-eight female volunteers, between the ages of 22 and 55 years and at least 25% overweight, participated in a weight reduction program. The program factorially varied 24 hr of restricted environmental stimulation (lying on a bed in a dark, silent room) and a set of self-management messages. The combined treatment was significantly more effective than the other three conditions during a 6 month follow-up period; the mean weight loss during the first 2 months was primarily a function of the messages, while the reduced stimulation environment effect became dominant during the last 4 months of follow-up.

    Clinically significant weight loss (CSWL) is ≥5% of initial weight. The purpose of the study is to determine factors associated with women achieving CSWL in Take Off Pounds Sensibly (TOPS), a national, nonprofit weight loss program. This is a retrospective analysis of 48,674 females who joined TOPS from 2005 to 2011 and had a birth date in the database. Predictors of CSWL were evaluated using log-binomial regression and adjusted relative risks [99% CI] for participant age, initial weight, number of members per chapter, and chapter age. Older women were more likely to achieve CSWL, with women ≥70 years 1.23 (1.18, 1.28) times more likely to achieve CSWL compared to women 18 to lose weight as those in chapters less than 10 years old. Women in TOPS were more likely to achieve CSWL if older, ≥113 kg, and in larger, newer chapters. Future studies should address ways to modify the program to improve achievement of CSWL.

    The purpose of this study was to evaluate participants' perceptions of the weight-loss intervention used in a hypertension prevention clinical trial. A total of 308 overweight and moderately obese subjects participated in the weight-management intervention. After the 18-month program, 281 participants completed a questionnaire designed to evaluate their perceptions of the program's effectiveness. Adult participants (224 men and 84 women) in the weight-loss modality of the Trials of Hypertension Prevention Phase I, surveyed in 1991. chi 2 Analyses were used to test for statistical significance of group differences. Intervention components that were most useful are presented. Older participants (older than 50 years) were most likely to attend sessions and women were most likely to identify stress and frustration because of disappointing results. Successful participants were more likely to incorporate exercise into their daily activities, exercise regularly, and use self-monitoring strategies. Few participants found group exercise to be useful. These findings suggest that interventionists in weight-loss programs need to find flexible and creative ways to maintain contact with participants, continue to develop better methods of self-monitoring, obtain the skills needed to recognize frustration and provide timely support, continue to couple the message of diet and exercise, and emphasize helping participants develop their problem-solving skills. This may require training outside the traditional field of dietetics.

    Weight stigma is a significant socio-structural barrier to reducing health disparities and improving quality of life for higher weight individuals. The aim of this study was to examine the impact of internalized weight stigma on eating behaviors after participating in a randomized controlled trial comparing the health benefits of a weight-neutral program to a conventional weight-management program for 80 community women with high body mass index (BMI > 30, age range: 30-45). Programs involved 6 months of facilitator-guided weekly group meetings using structured manuals. Assessments occurred at baseline, post-intervention (6 months), and 24-months post-randomization. Eating behavior outcome measurements included the Eating Disorder Examination-Questionnaire and the Intuitive Eating Scale. Intention-to-treat linear mixed models were used to test for higher-order interactions between internalized weight stigma, group, and time. Findings revealed significant 3-way and 2-way interactions between internalized weight stigma, group, and time for disordered and adaptive eating behaviors, respectively. Only weight-neutral program participants with low internalized weight stigma improved global disordered eating scores. Participants from both programs with low internalized weight stigma improved adaptive eating at 6 months, but only weight-neutral program participants maintained changes at follow-up. Participants with high internalized weight stigma demonstrated no changes in disordered and adaptive eating, regardless of program. In order to enhance the overall benefit from weight-neutral approaches, these findings underscore the need to incorporate more innovative and direct methods to reduce internalized weight stigma for women with high BMI.

    'Fetal programming' is a newly emerging field that is revealing astounding insights into the prenatal origins of adult disease, including metabolic, endocrine, and cardiovascular pathophysiology. In the present study, we tested the hypothesis that rat pups conceived, gestated and born at 2-g have significantly reduced birth weights and increased adult body weights as compared to 1-g controls. Offspring were produced by mating young adult male and female rats that were adapted to 2-g centrifugation. Female rats underwent conception, pregnancy and birth at 2-g. Newborn pups in the 2-g condition were removed from the centrifuge and fostered to non-manipulated, newly parturient dams maintained at 1-g. Comparisons were made with 1-g stationary controls, also cross- fostered at birth. As compared to 1-g controls, birth weights of pups gestated and born at 2-g were significantly reduced. Pup body weights were significantly reduced until Postnatal day (P)12. Beginning on P63, body weights of 2-g-gestated offspring exceeded those of 1-g controls by 7-10%. Thus, prenatal rearing at 2-g restricts neonatal growth and increases adult body weight. Collectively, these data support the hypothesis that 2-g centrifugation alters the intrauterine milieu, thereby inducing persistent changes in adult phenotype.

    Diet and/or exercise are routinely advised as methods for weight loss in overweight/obese individuals, particularly those who are at high risk for cardiovascular disease and type 2 diabetes mellitus. However, physical activity and structured exercise programs rarely result in significant loss of body weight or body fat, and weight-loss diets have extraordinarily high recidivism rates. Despite only modest effects on body weight, exercise and ad libitum nutrient-dense diets for overweight/obese individuals have many health benefits, including skeletal muscle adaptations that improve fat and glucose metabolism, and insulin action; enhance endothelial function; have favorable changes in blood lipids, lipoproteins, and hemostatic factors; and reduce blood pressure, postprandial lipemia and glycemia, and proinflammatory markers. These lifestyle-induced adaptations occur independently of changes in body weight or body fat. Thus, overweight/obese men and women who are at increased risk for cardiovascular disease and type 2 diabetes as a result of sedentary lifestyle, poor diet, and excess body weight should be encouraged to engage in regular physical activity and improve their diet, regardless of whether the healthier lifestyle leads to weight loss.

    Context • Weight loss and maintenance are associated with many health benefits, but long-term maintenance of weight loss remains elusive for many people. Overweight individuals are at higher risk than normal-weight individuals for stress-induced overeating. The use of stress-management tools in a weight loss program might decrease the physiological stress that fuels overeating and improve posttreatment maintenance of weight loss Objective • The study intended to compare the differences in outcomes between 2 approaches to achieving weight loss and changes in health-stress reduction and intuitive eating (IE)-during a 14-wk period. Design • The research team designed a small, randomized, controlled pilot study. Setting • The study took place at the University of Kentucky (Lexington, KY, USA). Participants • Men and women, aged 25 to 65 y, with a body mass index ≥30 but ≤40 kg/m2, were recruited through various outlets on a large college campus, and 33 enrolled in the study. Intervention • Participants were randomly assigned either to an IE or to a stress-reduction program (EBT) for a 7 wk intervention and a 7-wk follow-up period. Outcome Measures • Weight, blood pressure, stress, depression, and eating behaviors were measured at baseline, postintervention at week 7, and postintervention at week 14. Results • Participants were 69.7% female and 93.9% Caucasian. An intent-to-treat analysis was conducted on the main outcome of weight. At 14 wk, the EBT group had lost 4.4 ± 6.7 lb (1.99 ± 3.04 kg), and the IE group had lost 1.03 ± 6.10 lb (0.48 ± 2.77 kg). A repeated measures analysis of variance did not find any significant difference between groups for weight change (P = .36). Completers in the EBT group significantly improved blood pressure, perceived stress, and food addiction symptoms from baseline to 7 wk (P < .05). Only the changes in weight were maintained at 14 wk. Conclusions • The study suggested that the stress reduction approach may

    Full Text Available OBJECTIVE: We investigated the impact of weight loss on urinary albumin excretion (UAE and creatinine clearance in obese patients with metabolic syndrome. METHODS: Thirty-five obese patients undertook a 12-week calorie-restricted diet. The patients underwent a metabolic (oral glucose tolerance test, plasma lipids, and uric acid and renal hemodynamic evaluations (creatinine clearance and urinary albumin excretion before (phase 1, and after the 12-week diet (phase 2. RESULTS: After the dietary intervention, the subjects were divided into two groups: patients who achieved the target weight reduction (R: responders, n = 14, and patients who did not (NR: non-responders, n = 21. The patients in Group R showed an improvement in lipid profile, a decrease in UAE (median = 162.5 mg/24 hours, range: 0.8 to 292 mg/24 hours, at phase 1 versus 10.4 mg/24 hours, range: 1.6 to 22.4 mg/24 hours, at phase 2, and a significant reduction in creatinine clearance (121.4 ± 66.5 mL/min. in phase 1 to 92.9 ± 35.6 mL/min. at the end of phase 2, p = 0.001. In Group NR, no statistically significant differences were observed between phases 1 and 2. CONCLUSION: Body weight reduction has a positive impact on renal hemodynamics, decreasing urinary albumin excretion as well as glomerular hyperfiltration in obese patients with metabolic syndrome.

    Obesity is the major risk factor for OSA; however, weight loss reduces OSA to a variable extent. We aimed to assess whether size of the maxillomandibular skeletal enclosure influences the relationship between weight loss and OSA reduction. Obese males (≥ 30 kg/m2) with moderate-severe OSA (AHI > 15/h) participating in a 6-mo open-label weight loss program had craniofacial computed tomography (CT) scans before and after weight loss. CT scans were analysed using three-dimensional cephalometry. Maxillomandibular volume was calculated from skeletal landmarks on the mandible (condyle, gonion, menton) and maxilla (anterior nasal spine). Multiple regression analysis was used to test for moderating effects of maxillomandibular volume on relationship between changes in weight and apnea-hypopnea index (AHI). Fifty-two men (age 44.3 ± 8.8 y, AHI 42.9 ± 21.3 events/h, body mass index [BMI] 34.0 ± 2.7 kg/m2) had 7.4 ± 4.1% weight loss and 34.1 ± 32.4% AHI reduction at 6 months. BMI reduction modestly predicted AHI change (r2 = 0.17, P = 0.002). The interaction term of maxillomandibular volume and BMI change was a predictor of OSA improvement (P = 0.03), indicating maxillomandibular volume moderates this relationship. Subgroup analyses of patients by small, medium, and large maxillomandibular volume showed a strong correlation between weight loss and OSA improvement only in the small volume group (r = 0.654, P = 0.004). There was no relationship evident in those with large maxillomandibular volume (r = 0.05, P = 0.9). Maxillomandibular volume influences the relationship between weight loss and OSA improvement with an effect on AHI more evident in those with a smaller craniofacial skeleton. © 2016 Associated Professional Sleep Societies, LLC.

    Full Text Available Abstract Background Obesity is common in the U.S. and many individuals turn to commercial programs to lose weight. Our objective was to directly compare weight loss, waist circumference, and systolic and diastolic blood pressure (SBP, DBP outcomes between commercially available weight-loss programs. Methods We conducted a systematic review by searching MEDLINE and the Cochrane Database of Systematic Reviews from inception to November 2014 and by using references identified by commercial programs. We included randomized, controlled trials (RCTs of at least 12 weeks duration that reported comparisons with other commercial weight-loss programs. Two reviewers extracted information on mean change in weight, waist circumference, SBP and DBP and assessed risk of bias. Results We included seven articles representing three RCTs. Curves participants lost 1.8 kg (95%CI: 0.1, 3.5 kg more than Weight Watchers in one comparison. There was no statistically significant difference in waist circumference change among the included programs. The mean reduction in SBP for SlimFast participants was 4.5 mmHg (95%CI: 0.4, 8.6 mmHg more than that of Atkins participants in one comparison. There was no significant difference in mean DBP changes among programs. Conclusions There is limited evidence that any one of the commercial weight-loss programs has superior results for mean weight change, mean waist circumference change, or mean blood pressure change.

    The aim of this project was to evaluate the effectiveness of using social media to augment the delivery of, and provide support for, a weight management program delivered to overweight and obese individuals during a twenty four week intervention. Participants randomly divided into either one of two intervention groups or a control group. The two intervention groups were instructed to follow identical weight-management program. One group received the program within a Facebook group, along with a support network with the group, and the other intervention group received the same program in a booklet. The control group was given standard care. Participants' weight and other metabolic syndrome risk factors were measured at baseline and at weeks 6, 12, 18 and 24. The Facebook Group reported a 4.8% reduction in initial weight, significant compared to the CG only (p = 0.01), as well as numerically greater improvements in body mass index, waist circumference, fat mass, lean mass, and energy intake compared to the Pamphlet Group and the Control Group. These results demonstrate the potential of social media to assist overweight and obese individuals with respect to dietary and physical activity modifications for weight management, and justify further research into the inclusion of social media in clinical weight management programs. It is anticipated that social media will provide an invaluable resource for health professionals, as a low maintenance vehicle for communicating with patients, as well as a source of social support and information sharing for individuals undergoing lifestyle modifications.

    Due to advances in the field of oncology, survival rates for children with cancer have improved significantly. However, these childhood cancer survivors are at a higher risk for obesity and cardiovascular diseases and for developing these conditions at an earlier age. In this paper, we describe the rationale, conceptual framework, development process, novel components, and delivery plan of a behavioral intervention program for preventing unhealthy weight gain in survivors of childhood acute lymphoblastic leukemia (ALL). A Web-based program, the Healthy Eating and Active Living (HEAL) program, was designed by a multidisciplinary team of researchers who first identified behaviors that are appropriate targets for weight management in childhood ALL survivors and subsequently developed the intervention components, following core behavioral change strategies grounded in social cognitive and self-determination theories. The Web-based HEAL curriculum has 12 weekly self-guided sessions to increase parents' awareness of the potential impact of cancer treatment on weight and lifestyle habits and the importance of weight management in survivors' long-term health. It empowers parents with knowledge and skills on parenting, nutrition, and physical activity to help them facilitate healthy eating and active living soon after the child completes intensive cancer treatment. Based on social cognitive theory, the program is designed to increase behavioral skills (goal-setting, self-monitoring, and problem-solving) and self-efficacy and to provide positive reinforcement to sustain behavioral change. Lifestyle interventions are a priority for preventing the early onset of obesity and cardiovascular risk factors in childhood cancer survivors. Intervention programs need to meet survivors' targeted behavioral needs, address specific barriers, and capture a sensitive window for behavioral change. In addition, they should be convenient, cost-effective and scalable. Future studies are needed

    Maternal programming of offspring energy balance has been viewed as an adaptation in which the gestational environment prepares the offspring to thrive and reproduce in that same postnatal environment. Programming might have the opposite effect, however, when gestational and postnatal environments are mismatched. Gestational programming would represent a trade-off if the mother can maximize fitness in one possible energetic future but cannot maximize fitness in another. The vast majority of research concerns rats, mice, or sheep, and dams are typically food restricted by 30-70% of ad libitum intake resulting in low birth weight and adult obesity in offspring. Few previous studies have used a lower level of food restriction, and no experiments, to the best of our knowledge, were designed to determine whether the effects of gestational restriction have postgestational effects independent of the effects that occurred during gestation. In the present experiment, Syrian hamsters were either restricted to 90% of their ad libitum food intake or fed ad libitum during pregnancy. All litters were cross-fostered at birth and all were fed ad libitum during lactation. Half of the litters from ad libitum-fed pregnant dams were fostered to dams that had been food restricted during pregnancy and half of the litters from food-restricted pregnant dams were fostered to ad libitum-fed dams. The latter group allowed us to test the hypothesis that the effects of having a gestationally food-restricted mother affects offspring characteristics independent of the prenatal programming. First, we found significant increases in the postnatal body weight of the offspring of ad libitum-fed mothers fostered to food-restricted dams, supporting the hypothesis that the effects of gestational restriction carry over to postnatal maternal ability (e.g., milk yield, milk content, or parental behavior). Second, the carry-over effects of gestational food restriction on offspring postnatal body weight were

    Adult lesbian and bisexual (LB) women are more likely to be obese than adult heterosexual women. To address weight- and fitness-related health disparities among older LB women using culturally appropriate interventions, the Office on Women's Health (OWH) provided funding for the program, Healthy Weight in Lesbian and Bisexual Women (HWLB): Striving for a Healthy Community. This paper provides a description of the interventions that were implemented. Five research organizations partnered with lesbian, gay, bisexual, and transgender community organizations to implement healthy weight interventions addressing the needs of LB women 40 years and older. The interventions incorporated evidence-based recommendations related to physical activity and nutrition. Each group intervention developed site-specific primary objectives related to the overall goal of improving the health of LB women and included weight and waist circumference reduction as secondary objectives. A 57-item core health survey was administered across the five sites. At a minimum, each program obtained pre- and post-program assessments. Each program included the OWH-required common elements of exercise, social support, and education on nutrition and physical activity, but adopted a unique approach to deliver intervention content. This is the first time a multisite intervention has been conducted to promote healthy weight in older LB women. Core measurements across the HWLB programs will allow for pooled analyses, and differences in study design will permit analysis of site-specific elements. The documentation and analysis of the effectiveness of these five projects will provide guidance for model programs and future research on LB populations.

    Summertime has emerged as a high-risk period for weight gain among low-income minority youth who often experience a lack of resources when not attending school. Structured programming may be an effective means of reducing risk for obesity by improving obesogenic behaviors among these youth. The current multi-method study examined sedentary time, physical activity, and dietary intake among low-income urban minority girls in two contexts: an unstructured summertime setting and in the context of a structured 4-week community-based summer day camp program promoting physical activity. Data were analyzed using paired-sample t tests and repeated-measure analyses of variance with significance at the p programming. All improvements were independent of weight status and age, and African-American participants evidenced greater changes in physical activity during programming. The study concludes that structured, community-based summertime programming may be associated with fewer obesogenic behaviors in low-income urban youth and may be a powerful tool to address disparities in weight gain and obesity among high-risk samples.

    Energy production from biomasses can be an important resource that, when combined with other green energies such as wind power and solar plants, can contribute to reduce dependency on fossil fuels. The aim of this study is to assess how agriculture could contribute to the production of bio-energy. A multi-period Weighted Goal Programming model (MpWGP) has been applied to identify the optimal land use combinations that simultaneously maximise farmers' income and biomass energy production under three concurrent constraints: water, labour and soil availability. Alternative scenarios are considered that take into account the effect of climate change and social change. The MpWGP model was tested with data from the Rovigo county area (Italy) over a 15-year time period. Our findings show that trade-off exists between the two optimisation targets considered. Although the optimisation of the first target requires traditional agricultural crops, which are characterised by high revenue and a low production of biomass energy, the latter would be achievable with intensive wood production, namely, high-energy production and low income. Our results also show the importance of the constraints imposed, particularly water availability; water scarcity has an overall negative effect and specifically affects the level of energy production. - Research Highlights: {yields} The aim of this study is to assess how agriculture could contribute to the production of bio-energy. {yields} A multi-period (15-year) Weighted Goal Programming model (MpWGP) has been applied. {yields} We identify the optimal land use combinations that simultaneously maximise farmers' income and biomass energy production. {yields} Three concurrent constraints have been considered: water, labour and soil availability.{yields} Water scarcity has an overall negative effect and specifically affects the level of energy production.

    We evaluated the efficiency of selection for body weight in a cooperative village breeding program for Menz sheep of Ethiopia under smallholder farming system. The design of the program involved organizing villagers in a cooperative breeding group to implement selective breeding of their sheep. The program was jump-started through a one-time provision of elite rams from a central nucleus flock, but subsequent replacement rams were selected from within the village flocks. We also evaluated body weight trends in a village where cooperative breeding was not implemented and individual farmers managed their flocks under traditional breeding practices. Under traditional breeding practices, genetic progress over 8 years either stagnated or declined in all the weights recorded. In the cooperative villages, selection differentials of 2.44 and 2.45 kg were achieved in 2010 and 2011 selection seasons, respectively. Birth weight, 3-month weight and 6-month weight increased, respectively, by 0.49, 2.29 and 2.46 kg in the third-generation lambs over the base generation. Improved rams supplied from the central nucleus flock gave an initial genetic lift of 14.4% in the 6-month weight. This was higher than the gain achieved from selection in the village flocks, which was 5.2%. Our results showed that village-based genetic improvement in body weights under smallholder conditions could be feasible if appropriate designs are adopted and that commencing with elite central nucleus rams help jump-start village-based programs.

    Full Text Available Abstract Judo competitions are divided into weight classes. However, most athletes reduce their body weight in a few days before competition in order to obtain a competitive advantage over lighter opponents. To achieve fast weight reduction, athletes use a number of aggressive nutritional strategies so many of them place themselves at a high health-injury risk. In collegiate wrestling, a similar problem has been observed and three wrestlers died in 1997 due to rapid weight loss regimes. After these deaths, the National Collegiate Athletic Association had implemented a successful weight management program which was proven to improve weight management behavior. No similar program has ever been discussed by judo federations even though judo competitors present a comparable inappropriate pattern of weight control. In view of this, the basis for a weight control program is provided in this manuscript, as follows: competition should begin within 1 hour after weigh-in, at the latest; each athlete is allowed to be weighed-in only once; rapid weight loss as well as artificial rehydration (i.e., saline infusion methods are prohibited during the entire competition day; athletes should pass the hydration test to get their weigh-in validated; an individual minimum competitive weight (male athletes competing at no less than 7% and females at no less than 12% of body fat should be determined at the beginning of each season; athletes are not allowed to compete in any weight class that requires weight reductions greater than 1.5% of body weight per week. In parallel, educational programs should aim at increasing the athletes', coaches' and parents' awareness about the risks of aggressive nutritional strategies as well as healthier ways to properly manage body weight.

In view of this, the basis for a weight control program is provided in this manuscript, as follows: competition should begin within 1 hour after weigh-in, at the latest; each athlete is allowed to be weighed-in only once; rapid weight loss as well as artificial rehydration (i.e., saline infusion) methods are prohibited during the entire competition day; athletes should pass the hydration test to get their weigh-in validated; an individual minimum competitive weight (male athletes competing at no less than 7% and females at no less than 12% of body fat) should be determined at the beginning of each season; athletes are not allowed to compete in any weight class that requires weight reductions greater than 1.5% of body weight per week. In parallel, educational programs should aim at increasing the athletes', coaches' and parents' awareness about the risks of aggressive nutritional strategies as well as healthier ways to properly manage body weight.

    , forgetting or being too busy to implement changes, unusual circumstances, and emotional eating. Because the bulk of the free and commercially available online diet and nutritional tools conduct no evaluation research, it is difficult to determine which aspects of a program are successful and what are reasonable expectations of results. The results of this study suggest that online interventions based on small changes have the potential to gradually lead to clinically significant weight loss, but high attrition from publically available or "free" programs still remains a challenge. Adherence to and effectiveness of small habit changes may be improved through further tailoring to individual circumstances and psychological needs.

    The purpose of this document is to provide experience-based guidance in implementing a software process improvement program in any NASA software development or maintenance community. This guidebook details how to define, operate, and implement a working software process improvement program. It describes the concept of the software process improvement program and its basic organizational components. It then describes the structure, organization, and operation of the software process improvement program, illustrating all these concepts with specific NASA examples. The information presented in the document is derived from the experiences of several NASA software organizations, including the SEL, the SEAL, and the SORCE. Their experiences reflect many of the elements of software process improvement within NASA. This guidebook presents lessons learned in a form usable by anyone considering establishing a software process improvement program within his or her own environment. This guidebook attempts to balance general and detailed information. It provides material general enough to be usable by NASA organizations whose characteristics do not directly match those of the sources of the information and models presented herein. It also keeps the ideas sufficiently close to the sources of the practical experiences that have generated the models and information.

    To investigate whether a controlled physical training plan for overweight dogs during a weight loss program would improve cardiorespiratory fitness and better preserve lean body mass, compared with results for dogs undergoing a weight loss program based on caloric restriction alone. Prospective, nonrandomized clinical study. 19 client-owned overweight or obese dogs. All dogs were fed the same calorie-restricted diet rationed to achieve a weight loss rate of 1% to 2%/wk for 12 weeks. The fitness-and-diet (FD) group participated in a training program that included underwater and land-based treadmill exercise 3 times/wk. The diet-only (DO) group had no change in exercise routines. Daily activity before and during the intervention was recorded by accelerometry. Before and after intervention, heart rate during exercise was recorded to assess cardiovascular fitness, and body composition was analyzed by dual-energy x-ray absorptiometry. Differences between groups were evaluated with t tests and multiple regression analysis. Mean weight loss was 13.9% and 12.9% for the FD and DO groups, respectively (n = 8 dogs/group that completed the study). Mean accelerometer counts during intervention were 13% higher than baseline counts for the FD group. Heart rate during exercise declined after intervention in both groups. Lean body mass was preserved in the FD group and lost in the DO group during intervention. The controlled exercise plan used with a dietary weight loss program prevented loss of lean body mass in dogs. This finding supports inclusion of controlled physical training for obesity management in dogs.

    Most health care organizations struggle with the design and implementation of effective, systemwide improvement programs. In 2000, the University HealthSystem Consortium initiated a benchmarking project to identify the organizational elements that predict a successful perfermance improvement (PI) program and that are best suited to support change initiatives. Forty-one organizations completed a survey about the presence of critical components, processes used to improve performance, and organizational PI structures. Follow-up site visits were conducted at three organizations. CRITICAL SUCCESS FACTORS FOR A PI PROGRAM: Eight organizational success factors for an effective performance improvement program were identified: (1) Strong Administrative Fxecutive and Performance Improvement Leadership, (2) Active Involvement of the Board of Trustees, (3) Effective Oversight Structure, (4) Expert Performance Improvement Staff, (5) Physician Involvement and Accountability, (6) Active Staff Involvement, (7) Effective Use of Information Resources-Data Used for Decision Making, and (8) Effective Communication Strategy. The approach offered is grounded in the belief that effective organizational structures and processes are prerequisites to improving health care delivery. Although some empirical support for the proposed model is provided, additional research will be required to determine the effectiveness of this approach.

    Obesity has been reported to impair immune functions and lead to low-grade long-term inflammation; however, studies that have investigated the impact of weight loss on these among the young and slightly obese are limited. Thus, we investigated the effect of a 12-week weight management program with behavioral modifications on cell-mediated immune functions and inflammatory responses in young obese participants. Our hypothesis was that weight loss would result in improved immune functions and decreased inflammatory responses. Sixty-four participants (45 obese and 19 normal weight) finished the program. Obese (body mass index ≥25) participants took part in 5 group education and 6 individual counseling sessions. Normal-weight (body mass index 18.5-23) participants only attended 6 individual sessions. The goal for the obese was to lose 0.5 kg/wk by reducing their intake by 300 to 500 kcal/d and increasing their physical activity. Program participation resulted in a modest but significant decrease in weight (2.7 ± 0.4 kg, P obese. In the obese group, increase in phytohemagglutinin-stimulated interleukin-10 production, a TH2 and anti-inflammatory cytokine, approached significance after program participation (from 6181 ± 475 to 6970 ± 632 pg/mL, P = .06). No significant changes in proliferative responses to the optimal concentration of concanavalin A or phytohemagglutinin were observed in the obese after program participation. Collectively, modest weight loss did not change the cell-mediated immune functions significantly but did attenuate the inflammatory response in young and otherwise healthy obese adults.

    Unhealthy lifestyle is often related to overweight and obesity and thus to chronic diseases. Web-based programs might be an option for a comprehensive approach to improving long-term weight management. Data from a randomized controlled trial (RCT) evaluating the impact of a lifestyle program on weight reduction were used for a secondary analysis. The objectives were (a) to identify potential predictors for marked weight loss, (b) to explore associations of weight reduction with changes in health-related variables, and (c) to evaluate whether self-monitoring of the daily lifestyle is associated with weight loss. 67 subjects with a body mass index of 28-35 who underwent the 1-year 'Individual Health Management' (IHM) program were included in the analysis (mean age 49.8 years, 79% female). Two subgroups (high response: ≥7.5% weight reduction vs. low response: weight loss. 70% of the subjects fulfilled the criterion of high response. There were no statistically significant differences between the two subgroups with respect to sociodemographic and baseline data. Regression analysis failed to identify any predictors for the amount of weight reduction. Subjects with high response showed a more distinct improvement in life satisfaction and neurovegetative stability. The findings indicated an association between the level of self-monitoring and weight loss. More research is needed to establish optimal strategies for maximizing the longer-term maintenance of weight loss and prevention effects. For weight reduction, support strategies like feedback learning through self-monitoring, reporting systems, and self-performance measurement with questionnaires might ameliorate high-intensity lifestyle modification programs. © 2017 S.

    Trunk instability is one of main problems in survivors following stroke. We investigated the effects of weight-shift training (WST) on an unstable surface in sitting position on trunk control, proprioception, and balance in individuals with chronic hemiparetic stroke. Eighteen participants with chronic hemiparetic stroke were recruited and were allocated to either WST or control group. The WST group received a weight-shift training program for 30 min and then received a conventional exercise program for 30 min, while the control group received conventional exercise program for 60 min, five times a week for four weeks for both groups. In this randomized control study, we used three outcome measures: trunk reposition error (TRE), Trunk Impairment Scale (TIS), and Timed Up and Go (TUG) test. TRE was measured by each participant's reposition error to the target angle during his/her active trunk movement. TIS and TUG were examined for trunk control abilities and dynamic balance abilities, respectively. After training, TRE showed significantly greater improvement in the WST group (mean change, 1.67 ± 1.45˚) than the control group (mean change, 0.08 ± 1.05˚). The TIS score was significantly higher in the WST group (mean change, 2.33 ± 1.50) than the control group (mean change, 0.13 ± 0.83). The TUG test also showed a significant improvement in the WST group (mean change, 5.03 ± 1.88 sec) than the control group (mean change, 2.59 ± 1.86 sec). Our findings indicate that weight-shift training is beneficial for improving trunk control and proprioception in patients with chronic hemiparetic stroke.

    Obesity and the metabolic syndrome (MetS) are risk factors for left ventricular diastolic dysfunction (LVDD). However, little is known about the impact of successful weight reduction (WR) on diastolic function and physical performance.Obese subjects (øBMI 40.2 ± 8.6 kg/m(2)) underwent a 1-year WR program comprising diet and lifestyle components. Echocardiography and exercise capacity (6-minute walk) were performed at baseline and after 1 year. The distribution of weight reduction was split at the sample median and subjects were dichotomized in "successful WR" (% WR ≥ median, corresponding to a weight loss of 8%) and "failed-WR" (% WR obese subjects, 71 had LVDD at baseline. Obese patients with successful WR improved their MetS alterations, including fasting glucose, insulin, lipids, adipokines, blood pressure levels, and epicardial fat thickness. The same was not true for obesity with failed WR. Subjects with successful WR demonstrated significant improvement in echocardiographic LVDD parameters (median [interquartile range]): Δe' (2,5 [-1.0, 4.7], P severe obesity, successful long-term WR was associated with improved LV diastolic function and exercise capacity.

    The objective of this study was to investigate the effect of baseline sleep on baseline weight status and weight-loss responsiveness in obese adolescents. Twenty-five obese adolescents who participated in a 19-day summer camp-based immersion treatment (IT) program completed pre-intervention measures of sleep duration and quality, and pre- and post-intervention body mass index z-scores (zBMI) and waist circumference (WC) assessments. Objective measures of sleep were obtained by actigraphy for a random subset of six participants for 1 week pre- and post-intervention. Shorter weekday sleep durations and more sleep debt were related to higher pre-intervention WCs (r = -0.54, p = 0.01 and r = -0.56, p = 0.01), and lower subjective sleep quality was related to higher pre-intervention zBMIs (r = -0.49, p = 0.02). Longer weekend sleep durations and more sleep debt were related to smaller reductions in pre- to post-intervention zBMIs (r = -0.47, p = 0.04 and r = -0.51, p = 0.03). For the subgroup of adolescents who wore actigraphs pre- and post-intervention, an increase in their sleep durations (d = -0.25) and a reduction in their sleep latencies (d = 0.52), zBMIs (d = 0.31), and WCs (d = 0.20) were observed. These results provide further evidence linking poor sleep patterns and obesity in adolescence, and suggest that sleep patterns may impact the effectiveness of pediatric obesity interventions and that IT programs may improve sleep in obese adolescents. Overall, they provide support for addressing sleep problems as part of obesity interventions. Copyright © 2014 Elsevier B.V. All rights reserved.

    Evaluate the effects of an online commercial weight management program, with and without provision of a 'smart' scale with instructions to weigh daily and weekly tailored feedback, on weight loss and the frequency of body-weight self-monitoring. Participants (N = 92; body mass index 27-40 kg/m2) were randomized to 6 months of no-cost access to the Weight Watchers Online (WWO) platform alone, or enhanced with a cellular-connected 'smart' scale, instructions to weigh daily and weekly pre-scripted email feedback (Weight Watchers Online Enhanced [WWO-E]). The number of days that weight was self-monitored (via 'smart' scale in WWO-E and manually in WWO) was recorded automatically across the 6-month trial. Objective weight was measured at baseline, 3 and 6 months. While both groups achieved statistically significant weight loss, mean ± standard error weight loss did not differ between WWO-E and WWO at 3 months (5.1 ± 0.6 kg vs. 4.0 ± 0.7 kg, respectively; p = 0.257) or 6 months (5.3 ± 0.6 kg vs. 3.9 ± 0.7 kg, respectively; p = 0.116). However, a greater proportion of WWO-E lost ≥5% of initial body weight at 3 months (52.2% vs. 28.3%; p = 0.033), but not 6 months (43.5% vs. 30.4%; p = 0.280), compared with WWO. Mean ± standard deviation days with self-monitored weight was higher in WWO-E (80.5 ± 5.6; 44.7% of days) than WWO (12.0 ± 1.0; 6.7% of days; p weight loss (52% vs. 28%) in an online commercial weight management program. Both WWO and WWO-E produced significant weight loss over 6 months. While mean weight losses were slightly greater in the enhanced group, the difference was not statistically significant in this small sample. This study provides support for the clinical utility of online commercial weight management programs and the potential for supporting technology such as 'smart' scales to improve adherence to body-weight self-monitoring and clinical outcomes.

    Streamflow is not measured at every location in a stream network. Yet hydrologists, State and local agencies, and the general public still seek to know streamflow characteristics, such as mean annual flow or flood flows with different exceedance probabilities, at ungaged basins. The goals of this guide are to introduce and familiarize the user with the weighted multiple-linear regression (WREG) program, and to also provide the theoretical background for program features. The program is intended to be used to develop a regional estimation equation for streamflow characteristics that can be applied at an ungaged basin, or to improve the corresponding estimate at continuous-record streamflow gages with short records. The regional estimation equation results from a multiple-linear regression that relates the observable basin characteristics, such as drainage area, to streamflow characteristics.

    Overweight and obese youth, who face increased risk of medical complications including heart disease and type II diabetes, can benefit from sustainable physical activity interventions that result in weight loss. This study examined whether a 20-week exergame (i.e., videogame that requires gross motor activity) intervention can produce weight loss and improve psychosocial outcomes for 54 overweight and obese African-American adolescents. Participants were recruited from a public high school and randomly assigned to competitive exergame, cooperative exergame, or control conditions. All exergame participants were encouraged to play the Nintendo Wii Active game for 30-60 min per school day in a lunch-time or after-school program. Cooperative exergame participants worked with a peer to expend calories and earn points together, whereas competitive exergame participants competed against a peer. Control participants continued regular daily activities. Outcome measures included changes in weight, peer support, self-efficacy, and self-esteem, measured at baseline, and at ∼10 and 20 weeks. Growth curve analysis revealed that cooperative exergame players lost significantly more weight (mean = 1.65 kg; s.d. = 4.52) than the control group, which did not lose weight. The competitive exergame players did not differ significantly from the other conditions. Cooperative exergame players also significantly increased in self-efficacy compared to the control group, and both exergame conditions significantly increased in peer support more than the control group. Exergames, especially played cooperatively, can be an effective technological tool for weight loss among youth. Copyright © 2012 The Obesity Society.

    Background The Weight Loss Maintenance Trial (WLM) compared two long-term weight-maintenance interventions, a personal contact arm and an Internet arm, with a no-treatment control after an initial six-month Phase I weight loss program. The Internet arm focused on use of an interactive website for support of long-term weight maintenance. There is limited information about patterns of website use and specific components of an interactive website that might help promote maintenance of weight loss. Objective This paper presents a secondary analysis of the subset of participants in the Internet arm and focuses on website use patterns and features associated with long-term weight maintenance. Methods Adults at risk for cardiovascular disease (CVD) who lost at least 4 kilograms in an initial 20-week group-based, behavioral weight-loss program were trained to use an interactive website for weight loss maintenance. Of the 348 participants, 37% were male and 38% were African American. Mean weight loss was 8.6 kilograms. Participants were encouraged to log in at least weekly and enter a current weight for the 30-month study period. The website contained features that encouraged setting short-term goals, creating action plans, and reinforcing self-management habits. The website also included motivational modules, daily tips, and tailored messages. Based on log-in and weight-entry frequency, we divided participants into three website use categories: consistent, some, and minimal. Results Participants in the consistent user group (n = 212) were more likely to be older (P = .002), other than African American (P = .02), and more educated (P = .01). While there was no significant difference between website use categories in the amount of Phase I change in body weight (P = .45) or income (P = .78), minimal website users (n = 75) were significantly more likely to have attended fewer Phase I sessions (P = .001) and had a higher initial body mass index (BMI) (P website (P website

    An open-label, randomized, exploratory study of 44 healthy overweight subjects with cardio-metabolic syndrome (CMS) risk factors was conducted to assess the safety, tolerability, and efficacy of a proprietary lifestyle modification program without (DIET) and with (PROG) targeted nutraceutical supplementation, including phytosterols, antioxidants, probiotics, fish oil, berberine, and soy, pea, and whey proteins over 13 weeks. Key metrics were recorded at baseline and weeks 9 and 13. For the DIET and PROG groups, compliance was 85% and 86%, respectively, with no adverse events related to the diet or supplements. Twelve subjects discontinued participation before week 9 for reasons unrelated to the study. PROG subjects experienced greater decreases (p < 0.05) than DIET in body mass, fat mass, total cholesterol, LDL cholesterol, TG, cholesterol / HDL ratio, TG/HDL ratio, apolipoprotein B / apolipoprotein A1 ratio, and hs-CRP. The Framingham 10-year cardiovascular disease risk score decreased by 40% (p < 0.01) in the PROG arm versus no change for the DIET arm. As a pilot study, it was not possible to state whether the observed effects were the result of nutraceutical supplementation alone or the result of additive or synergistic interactions among diet, lifestyle modifications, and nutraceutical supplementation. Moreover, individuals with CMS risk factors following a lifestyle modification program received additional health benefits from targeted nutraceutical supplementation.

    2001-01-01

    As a test of a prevention effect, data were collected two years after boys and girls ages 9-11 completed ten one-hour lessons designed to improve nutrition and exercise patterns, enhance body esteem, and discourage unhealthy weight management. Body esteem, use of weight loss techniques, SATAQ scores, weight concerns, and program-related knowledge were compared among three groups of young adolescent girls and boys (N = 509; ages = 11-13): participants in the elementary school program (Smolak, Levine, & Schermer, 1998a, 1998b), control participants from the same elementary schools, and new control participants from schools not included in the original study. Compared to new controls, those adolescents who received the prevention program two years earlier were more knowledgeable, used fewer unhealthy weight management techniques, and had higher body esteem. The latter difference was particularly significant for girls. Original control participants had intermediate scores, suggesting a "spillover" effect. Scores on program-related knowledge were positively correlated with better body esteem and less frequent use of weight loss techniques, and lower SATAQ scores, particularly among the girls. Findings suggest that a curricular program using cognitive social learning and developmental principles may help prevent the development of negative body image and unhealthy weight management techniques in girls and boys as they move from late childhood to early adolescence. Important methodological implications of this study for the meaning of prevention also are discussed.

    The purpose of this study was to examine whether baseline sleep duration predicts weight loss outcomes in a randomized controlled trial examining a behavioral weight loss (BWL) intervention among overweight and obese (OW/OB) women with urinary incontinence; and whether participation in the BWL intervention is associated with changes in sleep duration. Longitudinal, clinical intervention study of a 6-month BWL program. Three hundred sixteen OW/OB women, with urinary incontinence (age: 30-81 years, body mass index (BMI; 25-50 kg m(-2)) enrolled from July 2004-April 2006. Measured height and weight, self-report measures of demographics, sleep and physical activity. Neither self-reported total sleep time (TST) nor time in bed (TIB) at baseline significantly predicted weight loss outcomes among OW/OB women in a BWL treatment. BWL treatment was successful regardless of how much subjects reported sleeping at baseline, with an average weight loss of 8.19 kg for OW/OB women receiving BWL treatment, versus a weight loss of 1.44 kg in the control condition. Similarly, changes in weight, BMI and incontinence episodes did not significantly predict changes in sleep duration or TIB across the treatment period. Although epidemiological and cross-sectional studies support a relationship between short sleep and increased BMI, the present study found no significant relationship between TST or TIB and weight loss for OW/OB women participating in a BWL treatment.

    Modern CT is a powerful yet increasingly complex technology that continues to rapidly evolve; optimal clinical implementation as well as appropriate quality management and improvement in CT are challenging but attainable. This article outlines the organizational structure on which a CT quality management and improvement program can be built, followed by a discussion of common as well as pediatric-specific challenges. Organizational elements of a CT quality management and improvement program include the formulation of clear objectives; definition of the roles and responsibilities of key personnel; implementation of a technologist training, coaching and feedback program; and use of an efficient and accurate monitoring system. Key personnel and roles include a radiologist as the CT director, a qualified CT medical physicist, as well as technologists with specific responsibilities and adequate time dedicated to operation management, CT protocol management and CT technologist education. Common challenges in managing a clinical CT operation are related to the complexity of newly introduced technology, of training and communication and of performance monitoring. Challenges specific to pediatric patients include the importance of including patient size in protocol and dose considerations, a lower tolerance for error in these patients, and a smaller sample size from which to learn and improve.

    The Veterans Health Administration (VHA) has implemented MOVE!, a weight-management program for veterans designed to address the increasing proportion of overweight and obese veterans. The objective of our study was to determine whether peer support employing motivational interviewing (MI) could positively influence lifestyle changes, thus expanding the reach of the MOVE! program. We describe the initial evaluation of the peer training program. We developed an MI peer ounselor training program for volunteer veterans, the "Buddies" program, to provide one-on-one telephone support for veterans enrolled in MOVE!. Buddies were recruited at 5 VHA sites and trained to provide peer support for the 6-month MOVE! intervention. We used a DVD to teach MI skills and followed with 2 to 3 booster sessions. We observed training, conducted pre- and posttraining surveys, and debriefed focus groups to assess training feasibility. Fifty-six Buddies were trained. Results indicate positive receipt of the program (89% reported learning about peer counseling and 87% reported learning communication skills). Buddies showed a small improvement in MI self-efficacy on posttraining surveys. We also identified key challenges to learning MI and training implementation. MI training is feasible to implement and acceptable to volunteer Buddies. Trainers must assess how effectively volunteers learn MI skills in order to enhance its effective use in health promotion.

    The Adaptive Maneuvering Logic (AML) computer program simulates close-in, one-on-one air-to-air combat between two fighter aircraft. Three important improvements are described. First, the previously available versions of AML were examined for their suitability as a baseline program. The selected program was then revised to eliminate some programming bugs which were uncovered over the years. A listing of this baseline program is included. Second, the equations governing the motion of the aircraft were completely revised. This resulted in a model with substantially higher fidelity than the original equations of motion provided. It also completely eliminated the over-the-top problem, which occurred in the older versions when the AML-driven aircraft attempted a vertical or near vertical loop. Third, the requirements for a versatile generic, yet realistic, aircraft model were studied and implemented in the program. The report contains detailed tables which make the generic aircraft to be either a modern, high performance aircraft, an older high performance aircraft, or a previous generation jet fighter.

  8. A multidisciplinary weight-loss program: the importance of psychological group therapy

    Full Text Available Abstract In addition to dietary factors and sedentary habits, there is a relationship between obesity and psychological variables, even without a clear distinction between cause, effect, and correlation. Despite this relationship, weight-loss programs are limited to a combination of nutrition and physical education, leaving psychological intervention out of the treatment plan. Self-esteem issues, depression, and anxiety are just some of the emotional conditions related to obesity. However, there is no information in the literature about the importance of psychological counseling in a multidisciplinary program for weight-loss in adults. In this context, the main objective of this study was to analyze the effect of cognitive-behavioral therapy in groups (CBTG combined with nutrition and physical education within a multidisciplinary approach to treat obesity. 46 individuals (7 men and 39 women were divided into two groups: control (GC and psychology (GP. Baseline and intervention measures were obtained prior to intervention and before the final meeting, including physical capacity tests and the administering the International Physical Activities Questionnaire (IPAQ. Both groups attended weekly lectures given by a nutritionist and two physical education professionals for 12 weeks. In addition, the GP participated in weekly sessions of CBTG for the same period. After the program, there were significant changes in body mass index, waist circumference, body fat percentage, and strength of the lower limbs in both groups. In addition to these changes, the GP also showed improvements in diastolic blood pressure and IPAQ scores, being the only one that increased its time of weekly physical activity. Thus, it was concluded that the psychological treatment might play an important role in a multidisciplinary weight-loss program.

    This study examined the response of parents of elementary school-aged children to a school-based body mass index (BMI) screening and parent notification program conducted in one Minnesota school district in 2010-2011 and whether parent's response was moderated by child's weight status. Randomly selected parents (N = 122) of second- and fourth-grade students completed a mailed self-administered anonymous survey. Child's weight status was determined using measured height and weight. Most parents read the BMI notification letter and considered it helpful, independent of child's weight status. Parents of overweight children were significantly more likely than parents of normal weight children to report healthy lifestyle changes. This low-intensity intervention has the potential to support children, especially overweight children, and their parents to make healthy lifestyle changes. Future studies should investigate whether parent's response contributes to improved short- and long-term health outcomes for children. © The Author(s) 2014.

    The objective of this randomized equivalence trial was to determine the impact of consuming lean beef as part of a high protein (HP) weight-reducing diet on changes in body weight, body composition and cardiometabolic health. A total of 120 adults (99 female) with overweight or obesity (BMI: 35.7 ± 7.0 kg m-2) were randomly assigned to consume either a HP diet with ≥4 weekly servings of lean beef (B; n = 60) or a HP diet restricted in all red meats (NB; n = 60) during a 16-week weight loss intervention. Body weight was reduced by 7.8 ± 5.9% in B and 7.7 ± 5.5% in NB (p equivalent between B and NB (mean difference: 0.06%, 90% confidence interval: (-1.7, 1.8)). Fat mass was reduced in both groups (p mass was not reduced in either group. Improvements in markers of cardiometabolic health (total cholesterol, low-density lipoprotein cholesterol, triglycerides and blood pressure) were not different between B and NB. Results of this study demonstrate that HP diets - either rich or restricted in red meat intakes - are effective for decreasing body weight and improving body composition and cardiometabolic health.

    Observational evidence from behavioral weight control trials and community studies suggests that greater frequency of weighing oneself, or tracking weight, is associated with better weight outcomes. Conversely, it has also been suggested that frequent weight tracking may have a negative impact on mental health and outcomes during weight loss, but there are minimal experimental data that address this concern in the context of an active weight loss program. To achieve the long-term goal of strengthening behavioral weight loss programs, the purpose of this randomized controlled trial (the Tracking Study) is to test variations on frequency of self-weighing during a behavioral weight loss program, and to examine psychosocial and mental health correlates of weight tracking and weight loss outcomes. This paper describes the study design, intervention features, recruitment, and baseline characteristics of participants enrolled in the Tracking Study. Three hundred thirty-nine overweight and obese adults were recruited and randomized to one of three variations on weight tracking frequency during a 12-month weight loss program with a 12-month follow-up: daily weight tracking, weekly weight tracking, or no weight tracking. The primary outcome is weight in kilograms at 24 months. The weight loss program integrates each weight tracking instruction with standard behavioral weight loss techniques (goal setting, self-monitoring, stimulus control, dietary and physical activity enhancements, lifestyle modifications); participants in weight tracking conditions were provided with wireless Internet technology (wi-fi-enabled digital scales and touchscreen personal devices) to facilitate weight tracking during the study. This study was successful in recruiting adult male and female participants and is positioned to enhance the standard of care with regard to weight tracking recommendations.

    Full Text Available Objective: Structured obesity treatment programs at primary care level are becoming increasingly important. However, evidence from current treatment approaches in the long term is lacking. In view of this fact we evaluated a standardized, meal replacement-based weight loss program (myLINE®; AENGUS, Graz, Austria according to the currently applicable guidelines. Methods: Data of overweight and obese individuals (n = 70 who participated at least 36 months in the program were analyzed. Data were collected at baseline (T0 as well as after 1, 3, 6, 12, 24, and 36 (T1-T36 months. Body composition was measured by conventional anthropometry and bioelectrical impedance analysis. Results: Compared to T0, a maximum weight, BMI, fat mass, absolute body cell mass (BCM reduction and an increase of relative BCM could be seen at T6. Subsequently, the findings reveal a significant reduction of body weight and body fat and a satisfying development of body cell mass during the observation period of 36 months. Conclusion: The evaluated program complies with national and international guidelines for the therapy of obesity in adults and is efficient and meaningful for a long-term therapeutic use in primary care..

    Full Text Available Obesity is related to high health care costs and lost productivity in the workplace. Employers are increasingly sponsoring weight loss and wellness programs to ameliorate these costs. We evaluated weight loss outcomes, treatment utilization, and health behavior change in a low intensity phone- and web-based, employer-sponsored weight loss program. The intervention included three proactive counseling phone calls with a registered dietician and a behavioral health coach as well as a comprehensive website. At six months, one third of those who responded to the follow-up survey had lost a clinically significant amount of weight (≥5% of body weight. Clinically significant weight loss was predicted by the use of both the counseling calls and the website. When examining specific features of the web site, the weight tracking tool was the most predictive of weight loss. Health behavior changes such as eating more fruits and vegetables, increasing physical activity, and reducing stress were all predictive of clinically significant weight loss. Although limited by the low follow-up rate, this evaluation suggests that even low intensity weight loss programs can lead to clinical weight loss for a significant number of participants.

    Perturbations of energy balance induce compensatory processes that may alter expected weight loss. In obese patients, our aim was to investigate the relationships that occurred between fasting plasma concentrations of anorexigenic peptides and metabolic parameters, appetite, physical capacity, and weight loss in the 5 first days of a program associating exercise and caloric reduction. Thirteen obese women were monitored from day 1 to day 5 with 2 exercise sessions in day 2 and day 4. We measured, in a fasted state, changes in body weight, hunger ratings, and plasma concentrations of fatty acids, triglycerides, leptin, insulin, amylin, peptide YY, and insulin-resistance index. Physical performance was assessed by a 6-min walking test. The program resulted in significantly reduced body weight (0.75±0.4 kg; p=0.001), of plasma concentrations of triglycerides, insulin, amylin, peptide YY, and the insulin-resistance index, and also increased fatty acids (pweight loss (r(2)=0.65, 0.57, 0.55; pweight loss, improved lipid profile, and decreased insulin resistance while hunger ratings increased. Subjects with higher physical capacity lost more weight, presented higher increases in fatty acids and lower changes of leptin and insulin concentrations suggesting a better metabolic flexibility. To reduce the compensatory responses that can occur with energy imbalances, our study supports to account for individual activity level before prescribing weight-loss program associating diet and exercise. © Georg Thieme Verlag KG Stuttgart · New York.

    The effect of intensity and duration of physical activity (PA) on weight loss has been well described. However, the effect of the frequency of weekly PA on weight loss is still unknown. The purpose of this study was to evaluate the effect of the frequency of weekly PA sessions while maintaining the same total activity time on weight loss during a 24-wk weight loss program. Overweight and obese women [n = 75; body mass index (BMI; in kg/m2): 27-37; age: 18-40 y] who had a normally sedentary lifestyle were randomly allocated to 1 of 2 intervention groups: a high-frequency physical activity (HF) or a low-frequency physical activity (LF) group. The HF group included 50 min/d PA, 6 d/wk (300 min/wk). The LF group included 100 min/d PA, 3 d/wk (300 min/wk). Both groups were advised to follow the same dietary weight loss program. Both groups showed a significant decrease in anthropometric measurements and significant improvements in cardiometabolic disease risk characteristics over the 24 wk of the study. Compared with the HF group, the LF group had a greater decrease in weight (mean ± SD; LF: 9.58 ± 3.77 kg; HF: 7.78 ± 2.68 kg; P = 0.028), BMI (LF: 3.62 ± 1.56; HF: 2.97 ± 1.02; P = 0.029) and waist circumference (LF: 9.36 ± 4.02 cm; HF: 7.86 ± 2.41 cm; P = 0.031). However, there were no significant differences in carbohydrate metabolism characteristics or lipid profile after the 24 wk of intervention. Weekly PA undertaken over fewer sessions of longer duration during the week could be more effective for weight loss than when undertaken as more frequent shorter sessions in overweight and obese women on a weight loss program. This may be helpful for those who are neither willing nor able to schedule time for PA almost every day to achieve weight loss.

    Weight loss is known to improve pain localized to weight-bearing joints but it is not known how weight loss affects the spatial distribution of pain and associated somatic symptoms like fatigue. We sought to determine if weight loss using a low-calorie diet improves pain, affect, and somatic symptoms commonly associated with chronic pain conditions in an observational study. We also documented changes in inflammatory markers in serum before and after weight loss. Participants were 123 obese individuals undergoing a 12- to 16-week calorie restriction weight loss intervention. The spatial distribution of pain, symptom severity (eg, fatigue, sleep difficulties), depression, and total fibromyalgia scale scores were measured before and after weight loss. Pain (P = . 022), symptom severity (P = .004), depression (P loss; men showed greater improvement than women on somatic symptoms and fibromyalgia scores (both P loss may improve diffuse pain and comorbid symptoms commonly seen in chronic pain participants. This article presents the effect of a weight loss intervention on characteristics of chronic pain, including the spatial distribution of pain and comorbid somatic symptoms. Weight loss appeared to produce larger improvements in somatic symptoms for men. Copyright © 2017 The American Pain Society. Published by Elsevier Inc. All rights reserved.

    Weight loss reduces abdominal and intrahepatic fat, thereby improving metabolic and cardiovascular risk. Yet, many patients regain weight after successful diet-induced weight loss. Long-term changes in abdominal and liver fat, along with liver test results and insulin resistance, are not known. We analyzed 50 overweight to obese subjects (46 ± 9 years of age; BMI, 32.5 ± 3.3 kg/m2; women, 77%) who had participated in a 6-month hypocaloric diet and were randomized to either reduced carbohydrates or reduced fat content. Before, directly after diet, and at an average of 24 (range, 17-36) months follow-up, we assessed body fat distribution by magnetic resonance imaging and markers of liver function and insulin resistance. Body weight decreased with diet but had increased again at follow-up. Subjects also partially regained abdominal subcutaneous and visceral adipose tissue. In contrast, intrahepatic fat decreased with diet and remained reduced at follow-up (7.8 ± 9.8% [baseline], 4.5 ± 5.9% [6 months], and 4.7 ± 5.9% [follow-up]). Similar patterns were observed for markers of liver function, whole-body insulin sensitivity, and hepatic insulin resistance. Changes in intrahepatic fat und intrahepatic function were independent of macronutrient composition during intervention and were most effective in subjects with nonalcoholic fatty liver disease at baseline. A 6-month hypocaloric diet induced improvements in hepatic fat, liver test results, and insulin resistance despite regaining of weight up to 2 years after the active intervention. Body weight and adiposity measurements may underestimate beneficial long-term effects of dietary interventions.

    Obesity disproportionately burdens individuals with serious mental illness (SMI), especially women. This observational study investigated whether there were sex differences in weight loss and program participation among veterans with SMI enrolled in the Veterans Health Administration's (VHA) MOVE! weight management program. Participants were identified from a national cohort of 148,254 veterans enrolled in MOVE! during fiscal years 2008 through 2012 who attended two or more sessions within 12 months of enrollment. The cohort included those with International Classification of Disease, 9th Edition, Clinical Modification (ICD-9-CM) diagnoses for SMI, age less than 70 years, and weight data at baseline and one or more follow-up timepoints within approximately 1 year of enrollment (n = 8,943 men; n = 2,245 women). Linear mixed models assessed associations of sex with 6- and 12-month weight change from baseline, adjusting for demographic- and site-level variables. Both sexes averaged 6.4 (standard deviation, 4.6) sessions within 12 months; however, women with and without SMI participated at rates double their respective proportion rates among all VHA users. Participants averaged statistically significant weight loss at 6 months (men, -2.5 lb [95% CI, -2.8 to -2.1]; women, -2.4 lb [95% CI, -3.1 to -1.7]) and 12 months (men, -2.5 lb [95% CI, -2.8 to -2.2]; women, -2.9 lb [95% CI, -3.6 to -2.2]), but no sex-based difference in absolute weight loss at either timepoint. Slightly more women achieved 5% or greater (clinically significant) weight loss at the 12-month follow-up than did men (25.7% vs. 23.0%; p Women with SMI participated in MOVE! at rates equivalent to or greater than men with SMI, with comparable weight loss. More women were Black, single, had bipolar and posttraumatic stress disorder, and higher service-connected disability, suggesting areas for program customization. Published by Elsevier Inc.

    Full Text Available Background. Worksite wellness programs typically produce modest weight losses. We examined whether an efficacious Internet behavioral weight loss program could be successfully implemented in a worksite setting. Methods. Participants were 75 overweight or obese employees/dependents of a large healthcare system who were given access to a 12-week Internet-based, multicomponent behavioral weight loss program. Assessments occurred at baseline, Month 3 (end of intervention, and Month 6 (follow-up. Results. Retention was excellent (93% at Month 3 and 89% at Month 6. Intent-to-treat analyses demonstrated that participants lost an average (±SE of -5.8±.60 kg from baseline to Month 3 and regained 1.1±.31 kg from Month 3 to Month 6; overall, weight loss from baseline to Month 6 was -4.7±.71 kg, p<.001. Men lost more weight than women, p=.022, and individuals who had a college degree or higher lost more weight than those with less education, p=.005. Adherence to viewing lessons (8 of 12 and self-monitoring (83% of days was excellent and significantly associated with weight loss, ps<.05. Conclusions. An Internet-based behavioral weight management intervention can be successfully implemented in a worksite setting and can lead to clinically significant weight losses. Given the low costs of offering this program, it could easily be widely disseminated.

    Weight loss is a part of any competitive sport which matches participants of equal weight or sports where participating at lower weights or with a thinner body habitus is considered an advantage. For some wrestlers, weight loss is excessive and often accomplished by methods that lead to loss of lean body mass and total body water. There is convincing evidence that this excessive weight loss is unhealthy for all individuals who follow these practices. Even greater harm is experienced by high school wrestlers who have not yet completed their growth and development. These health consequences include growth retardation, decreased academic performance, altered endocrine or hormonal function and damage to many vital organs. "cycling" of weight results in decrease in strength, power and endurance which would effect adversely a wrestler's likelihood of success. The VHSL has begun an educational program to inform coaches, wrestlers and parents about the hazards inherent in these weight loss practices. History suggests that education alone will not alter the present practices of weight loss. Therefore a weight management program similar to ones initiated in other states is being pursued by the VHSL. The pilot program this year is scheduled to be followed next year by a more wide-spread voluntary program across the Commonwealth.(ABSTRACT TRUNCATED AT 250 WORDS)

    1997-01-01

    With the advancing computer processing capabilities, practical computer applications are mostly limited by the amount of human programming required to accomplish a specific task. This necessary human participation creates many problems, such as dramatically increased cost. To alleviate the problem, computers must become more autonomous. In other words, computers must be capable to program/reprogram themselves to adapt to changing environments/tasks/demands/domains. Evolutionary computation offers potential means, but it must be advanced beyond its current practical limitations. Evolutionary algorithms model nature. They maintain a population of structures representing potential solutions to the problem at hand. These structures undergo a simulated evolution by means of mutation, crossover, and a Darwinian selective pressure. Genetic programming (GP) is the most promising example of an evolutionary algorithm. In GP, the structures that evolve are trees, which is a dramatic departure from previously used representations such as strings in genetic algorithms. The space of potential trees is defined by means of their elements: functions, which label internal nodes, and terminals, which label leaves. By attaching semantic interpretation to those elements, trees can be interpreted as computer programs (given an interpreter), evolved architectures, etc. JSC has begun exploring GP as a potential tool for its long-term project on evolving dextrous robotic capabilities. Last year we identified representation redundancies as the primary source of inefficiency in GP. Subsequently, we proposed a method to use problem constraints to reduce those redundancies, effectively reducing GP complexity. This method was implemented afterwards at the University of Missouri. This summer, we have evaluated the payoff from using problem constraints to reduce search complexity on two classes of problems: learning boolean functions and solving the forward kinematics problem. We have also

    It has been recognized that reduction of abdominal visceral fat and subcutaneous fat are associated with improvement in insulin-resistance (IR) after weight loss. However, few studies have investigated the correlation of reduction in epicardial adipose tissue (EAT) with improvement of IR index after weight loss in obese non-diabetic men with metabolic syndrome (MetS). We prospectively enrolled 32 non-diabetic men with MetS for a 3-month weight reduction program mainly by diet control and exercise. Magnetic resonance imaging (MRI) examinations were used to measure EAT, subcutaneous fat, and abdominal visceral fat. Anthropometric parameters, oral glucose tolerance test (OGTT), and serum adipokines were assessed before and after the weight loss program. After a 3-month weight loss program, 27 obese MetS men had significant weight loss >5% (97 ± 14 to 87 ± 14 kg, with a 10.7 % decrease, p fat area (r = -0.673, p = 0.006) were significantly correlated with improvement of OGTT-derived Matsuda insulin-sensitivity index. The decrement ratio of SIVG EAT correlated with improvement of both HOMA-IR and OGTT-derived Matsuda insulin-sensitivity indexes after weight loss in obese non-diabetic men with MetS.

    Active video games may offer an effective strategy to increase physical activity in overweight and obese children. However, the specific effects of active gaming when delivered within the context of a pediatric weight management program are unknown. To evaluate the effects of active video gaming on physical activity and weight loss in children participating in an evidence-based weight management program delivered in the community. Group-randomized clinical trial conducted during a 16-week period in YMCAs and schools located in Massachusetts, Rhode Island, and Texas. Seventy-five overweight or obese children (41 girls [55%], 34 whites [45%], 20 Hispanics [27%], and 17 blacks [23%]) enrolled in a community-based pediatric weight management program. Mean (SD) age of the participants was 10.0 (1.7) years; body mass index (BMI) z score, 2.15 (0.40); and percentage overweight from the median BMI for age and sex, 64.3% (19.9%). All participants received a comprehensive family-based pediatric weight management program (JOIN for ME). Participants in the program and active gaming group received hardware consisting of a game console and motion capture device and 1 active game at their second treatment session and a second game in week 9 of the program. Participants in the program-only group were given the hardware and 2 games at the completion of the 16-week program. Objectively measured daily moderate-to-vigorous and vigorous physical activity, percentage overweight, and BMI z score. Participants in the program and active gaming group exhibited significant increases in moderate-to-vigorous (mean [SD], 7.4 [2.7] min/d) and vigorous (2.8 [0.9] min/d) physical activity at week 16 (P video gaming into an evidence-based pediatric weight management program has positive effects on physical activity and relative weight.

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

    To compare the efficacy of non-nutritive sweetened beverages (NNS) or water for weight loss during a 12-week behavioral weight loss treatment program. An equivalence trial design with water or NNS beverages as the main factor in a prospective randomized trial among 303 men and women was employed. All participants participated in a behavioral weight loss treatment program. The results of the weight loss phase (12 weeks) of an ongoing trial (1 year) that is also evaluating the effects of these two treatments on weight loss maintenance were reported. The two treatments were not equivalent with the NNS beverage treatment group losing significantly more weight compared to the water group (5.95 kg versus 4.09 kg; P water group during 12 weeks. These results show that water is not superior to NNS beverages for weight loss during a comprehensive behavioral weight loss program. Copyright © 2014 The Obesity Society.

    Full Text Available Android malware detection is a complex and crucial issue. In this paper, we propose a malware detection model using a support vector machine (SVM method based on feature weights that are computed by information gain (IG and particle swarm optimization (PSO algorithms. The IG weights are evaluated based on the relevance between features and class labels, and the PSO weights are adaptively calculated to result in the best fitness (the performance of the SVM classification model. Moreover, to overcome the defects of basic PSO, we propose a new adaptive inertia weight method called fitness-based and chaotic adaptive inertia weight-PSO (FCAIW-PSO that improves on basic PSO and is based on the fitness and a chaotic term. The goal is to assign suitable weights to the features to ensure the best Android malware detection performance. The results of experiments indicate that the IG weights and PSO weights both improve the performance of SVM and that the performance of the PSO weights is better than that of the IG weights.

It is a 3-month program followed by a 1-year follow-up. The results from the first 2 years are presented here to indicate the possibility of its further adaptation and implementation in this region. Methodology: We recruited 45 participants with obesity and/or type 2 diabetes based on inclusion/exclusion criteria. The LIFE-8 program was executed by incorporating dietary modification, physical activity, and behavioral therapy, aiming to achieve up to 5% weight loss. The outcomes included body weight, fat mass, waist circumference, blood pressure, fasting blood glucose (FBG, hemoglobin A1c (HbA1c, and nutritional knowledge at 3 months and 12 months. Results: We observed a reduction of 5.0% in body weight (4.8±2.8 kg; 95% CI 3.7–5.8, fat mass (–7.8%, P<0.01, and waist circumference (Δ=4±4 cm, P<0.01 in the completed participants (n=28.

    This study examined the effects of a standardized hand hygiene program on the rate of nosocomial infection (NI) in very low birth weight (VLBW) infants (birth weight antimicrobial soap (4% chlorhexidine gluconate) and alcohol-based hand rubs. NI after 72 hours of life was detected in 16 of the 85 VLBW infants in the first period and in 5 of the 80 VLBW infants in the second period. The rate of central venous catheter colonization was significantly lower in the second period (5.8%) than in the first period (16.6%). In our NICU, the incidence of NI in VLBW infants was significantly reduced after the introduction of a standardized handwashing protocol. In our experience, a proper hand hygiene program can save approximately 10 NI episodes/year, at a cost of $10,000 per episode. Therefore, improving hand hygiene practice is a cost-effective program in the NICU.

    A family-based multidisciplinary weight management program for obese children 7-11 years old was implemented by a pediatric weight management center and local YMCA. The purpose of this study was to explore parents' and children's perceptions of the program to gain insight about factors that may enhance engagement and retention of families in weight management treatment. Families were invited to participate in a telephone interview after their participation in the program. The interviews assessed satisfaction with program components, acceptability of the intervention, barriers to treatment participation, and suggestions for improvement. A total of 34 semistructured telephone interviews were performed, including 19 parents and 15 children. The majority of children (mean age=9.2±1.5 years) interviewed were female (74%) and recipients of Medicaid (79%). The population was racially diverse (63% black, 26% white, 11% other). Results suggest families were generally very positive about the program and viewed the major components of the program as helpful (i.e., nutrition, exercise, behavior). Families particularly enjoyed exercise and cooking demonstrations, whereas self-monitoring activities and learning about behavior change strategies were less enjoyable. Parents noted that increasing the length of individual sessions would likely be beneficial. Families who did not complete the program cited factors such as transportation barriers (e.g., gas money, distance), scheduling conflicts, and unmet expectations as contributing to their decision to discontinue participation. This study may have implications for how to enhance family-based pediatric weight management programs for children ages 7-11 years.

    The health outcomes of men continue to be poorer than women globally. Challenges in addressing this problem include difficulties engaging men in weight loss programs as they tend to view these programs as contrary to the masculine narrative of independence and self-reliance. Researchers have been turning towards sports fans to engage men in health promotion programs as sports fans are typically male, and tend to have poor health habits. Developed from the highly successful gender-sensitized Football Fans in Training program, Hockey Fans in Training (Hockey FIT) recruited 80 male hockey fans of the London Knights and Sarnia Sting who were overweight or obese into a weekly, 90-minute classroom education and group exercise program held over 12 weeks; a 40-week minimally-supported phase followed. A process evaluation of the Hockey FIT program was completed alongside a pragmatic randomized controlled trial and outcome evaluation in order to fully explore the acceptability of the Hockey FIT program from the perspectives of coaches delivering and participants engaged in the program. Data sources included attendance records, participant focus groups, coach interviews, assessment of fidelity (program observations and post-session coach reflections), and 12-month participant interviews. Coaches enjoyed delivering the program and found it simple to deliver. Men valued being among others of similar body shape and similar weight loss goals, and found the knowledge they gained through the program helped them to make and maintain health behaviour changes. Suggested improvements include having more hockey-related information and activities, greater flexibility with timing of program delivery, and greater promotion of technology support tools. We confirmed Hockey FIT was an acceptable "gender-sensitized" health promotion program for male hockey fans who were overweight or obese. Minor changes were required for optimization, which will be evaluated in a future definitive trial

    Cooper completed an investigation into new tire technology using a novel approach to develop and demonstrate a new class of fuel efficient tires using innovative materials technology and tire design concepts. The objective of this work was to develop a new class of fuel efficient tires, focused on the “replacement market” that would improve overall passenger vehicle fuel efficiency by 3% while lowering the overall tire weight by 20%. A further goal of this project was to accomplish the objectives while maintaining the traction and wear performance of the control tire. This program was designed to build on what has already been accomplished in the tire industry for rolling resistance based on the knowledge and general principles developed over the past decades. Cooper’s CS4 (Figure #1) premium broadline tire was chosen as the control tire for this program. For Cooper to achieve the goals of this project, the development of multiple technologies was necessary. Six technologies were chosen that are not currently being used in the tire industry at any significant level, but that showed excellent prospects in preliminary research. This development was divided into two phases. Phase I investigated six different technologies as individual components. Phase II then took a holistic approach by combining all the technologies that showed positive results during phase one development.

  5. Strategies to Improve Adherence to Dietary Weight Loss Interventions in Research and Real-World Settings.

    Dietary interventions are the cornerstone of obesity treatment. The optimal dietary approach to weight loss is a hotly debated topic among health professionals and the lay public alike. An emerging body of evidence suggests that a higher level of adherence to a diet, regardless of the type of diet, is an important factor in weight loss success over the short and long term. Key strategies to improve adherence include designing dietary weight loss interventions (such as ketogenic diets) that help to control the increased drive to eat that accompanies weight loss, tailoring dietary interventions to a person's dietary preferences (and nutritional requirements), and promoting self-monitoring of food intake. The aim of this paper is to examine these strategies, which can be used to improve adherence and thereby increase the success of dietary weight loss interventions.

    Physician counselling may help patients increase physical activity, improve nutrition and lose weight. However, physicians have low outcome expectations that patients will change. The aims are to describe the accuracy of physicians' outcome expectations about whether patients will follow weight loss, nutrition and physical activity recommendations. The relationships between physician outcome expectations and patient motivation and confidence also are assessed. This was an observational study that audio recorded encounters between 40 primary care physicians and 461 of their overweight or obese patients. We surveyed physicians to assess outcome expectations that patients will lose weight, improve nutrition and increase physical activity after counselling. We assessed actual patient change in behaviours from baseline to 3 months after the encounter and changes in motivation and confidence from baseline to immediately post-encounter. Right after the visit, ~55% of the time physicians were optimistic that their individual patients would improve. Physicians were not very accurate about which patients actually would improve weight, nutrition and physical activity. More patients had higher confidence to lose weight when physicians thought that patients would be likely to follow their weight loss recommendations. Physicians are moderately optimistic that patients will follow their weight loss, nutrition and physical activity recommendations. Patients might perceive physicians' confidence in them and thus feel more confident themselves. Physicians, however, are not very accurate in predicting which patients will or will not change behaviours. Their optimism, although helpful for patient confidence, might make physicians less receptive to learning effective counselling techniques.

    Weight loss is associated with improvements in cardiometabolic risk factors, including serum glucose, insulin, C-reactive protein, and blood lipids. Few studies have evaluated the long-term (>18 months) effect of weight loss on these risk factors or sought to identify factors associated with sustained improvements in these measures. In 417 overweight/obese women (mean [SD] age, 44 [10] years) participating in a weight loss trial, we sought to identify predictors of weight loss-associated cardiometabolic risk factors after 12 and 24 months of intervention. Total cholesterol (TC), low-density lipoprotein (LDL)-cholesterol (LDL-C), high-density lipoprotein (HDL)-cholesterol, non-HDL-cholesterol, triglycerides (TG), insulin, glucose, C-reactive protein (CRP), and cardiopulmonary fitness were measured at baseline and at 12 and 24 months. After 24 months, significant reductions in body weight, waist circumference, CRP, TC, HDL-cholesterol, and non-HDL-cholesterol were observed (Pweight lost, whereas reductions in LDL-cholesterol, CRP, insulin, and TG were observed only in those who lost ≥10% body weight. Step-test performance improved only in those who lost ≥10% body weight after 24 months. Change in weight demonstrated a positive predictive value for change in cholesterol, insulin, glucose, and triglycerides. Baseline level of the biomarker showed the greatest predictive value for follow-up measures for insulin, cholesterol, glucose, and triglycerides. Our data extend the results from short-term weight loss trials and suggest that the magnitude of weight loss and baseline values for risk factors are associated with improvements in cardiometabolic risk factors even after 24 months. http://www.clinicaltrials.gov/.

    Calorie restriction–induced weight loss is accompanied by profound changes in adipose tissue characteristics. To determine the effect of weight loss on differentiation of preadipocytes and secretory capacity of in vitro differentiated adipocytes, we established cultures of these cells from paired subcutaneous adipose tissue biopsies obtained before and at the end of weight-reducing dietary intervention (DI) in 23 obese women. Based on lipid accumulation and the expression of differentiation markers, in vitro adipogenesis increased after weight loss and it was accompanied by enhanced expression of genes involved in de novo lipogenesis. This effect of weight loss was not driven by changes of peroxisome proliferator–activated receptor γ sensitivity to rosiglitazone. Weight loss also enhanced the expression of adiponectin and leptin while reducing that of monocyte chemoattractant protein 1 and interleukin-8 by cultured adipocytes. Thus, the weight-reducing (DI) increased adipogenic capacity of preadipocytes and shifted their secretion toward lower inflammatory profile. Reprogramming of preadipocytes could represent an adaptation to weight loss leading to partial restoration of preobese adipose tissue traits and thus contribute to the improvement of metabolic status. However, enhanced adipogenesis could also contribute to the unwanted weight regain after initial weight loss. PMID:23378611

    Adaptive optics is an important technology for improving beam quality in solid-state slab lasers. However, there are uncorrectable aberrations in partial areas of the beam. In the criterion of the conventional least-squares reconstruction method, it makes the zones with small aberrations nonsensitive and hinders this zone from being further corrected. In this paper, a weighted least-squares reconstruction method is proposed to improve the relative sensitivity of zones with small aberrations and to further improve beam quality. Relatively small weights are applied to the zones with large residual aberrations. Comparisons of results show that peak intensity in the far field improved from 1242 analog digital units (ADU) to 2248 ADU, and beam quality β improved from 2.5 to 2.0. This indicates the weighted least-squares method has better performance than the least-squares reconstruction method when there are large zonal uncorrectable aberrations in the slab laser system.

The aim of the present paper is to systematically review the current knowledge of the effect on overall asthma control of weight reduction in overweight and obese adults with asthma.Results: Weight loss in obese individuals with doctor-diagnosed asthma is associated with a 48%–100% remission of asthma symptoms and use of asthma medication. Published studies, furthermore, reveal that weight loss in obese asthmatics improves asthma control, and that especially surgically induced weight loss results in significant improvements in asthma severity, use of asthma medication, dyspnoea, exercise tolerance, and acute exacerbations, including hospitalizations due to asthma. Furthermore, weight loss in obese asthmatics is associated with improvements in level of lung function and airway responsiveness to inhaled methacholine, whereas no significant improvements have been observed in exhaled nitric oxide or other markers of eosinophilic airway inflammation.Conclusion: Overweight and obese adults with asthma experience a high symptomatic remission rate and significant improvements in asthma control, including objective measures of disease activity, after weight loss. Although these positive effects of weight loss on asthma-related health outcomes seem not to be accompanied by remission or improvements in markers of eosinophilic airway inflammation, it has potentially important implications for the future burden of asthma.Keywords: asthma, weight loss, diet, bariatric surgery, asthma control

    This study provides updated information regarding the prevalence and characteristics of weight stigma in popular adolescent television programming, using a sample of favorite shows named by diverse adolescents. Participants in a large, population-based study of Minnesota adolescents (N = 2,793, mean age = 14.4) listed their top three favorite television shows. A coding instrument was developed to analyze randomly selected episodes from the most popular 10 programs. Weight-stigmatizing incidents were compared across television show characteristics and characters' gender and weight status. Half (50%) of the 30 episodes analyzed contained at least one weight-stigmatizing incident. Both youth- and adult-targeted shows contained weight-stigmatizing comments, but the percent of these comments was much higher for youth-targeted (55.6%) than general audience-targeted shows (8.3%). Male characters were more likely than females to engage in (72.7% vs. 27.3%), and be the targets of, weight stigma (63.6% vs. 36.4%), and there was no difference in the amount of weight stigmatizing directed at average weight females compared to overweight females. Targets of these instances showed a negative response in only about one-third of cases, but audience laughter followed 40.9% of cases. The portrayal of weight stigmatization on popular television shows-including targeting women of average weight-sends signals to adolescents about the wide acceptability of this behavior and the expected response, which may be harmful. Prevention of weight stigmatization should take a multi-faceted approach and include the media. Future research should explore the impact that weight-related stigma in television content has on viewers. © 2014 Wiley Periodicals, Inc.

    Not every participant responds with a comparable body weight loss to lifestyle intervention, despite the same compliance. Genetic factors may explain parts of this difference. Variation in fat mass and obesity-associated gene (FTO) is the strongest common genetic determinant of body weight. The aim of the present study was to evaluate the impact of FTO genotype differences in the link between improvement of fitness and reduction of body weight during a lifestyle intervention. We genotyped 292 healthy subjects for FTO rs8050136. Participants underwent a 9-month lifestyle intervention. Before and after intervention, aerobic fitness was tested by bicycle (VO2max) and treadmill spiroergometry (individual anaerobic threshold (IAT), subgroup of N = 192). Participants lost body weight (p weight (p obesity-risk A-allele carriers in the higher quartiles of improvement in fitness lost significantly less body weight. Our data reveal that genetic variation in FTO impacts on body weight reduction during lifestyle intervention only in subjects with marked improvement in aerobic fitness. © 2016 The Author(s) Published by S.

    To describe the comparative efficacy of orlistat and sibutramine in an obesity management program, with specific attention to compliance and weight regains after noncompliance. We prospectively evaluated 182 obese patients who were randomized to treatment with orlistat (n=98) or sibutramine (n=84) along with the diet and exercise prescriptions. Compliance (or compliant patient) was defined as adherence to scheduled visit times (at 3- month intervals) and following the prescribed drug regimen. A telephone survey was conducted in case of noncompliance. Significant body weights improvements were seen in both treatment groups. Patients lost a mean of 7.6+/-2.8% and 10.5+/-2.9% of initial body weights after a mean drug use of 8.8+/-5.7 and 8.3+/-3.7 months in the orlistat and sibutramine groups, respectively (p0.05 between groups). Both drugs in an obesity management program can achieve substantial weight loss. However, noncompliance and rebound weight regain after noncompliance are considerable problems.

    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.

    Obesity and a sedentary lifestyle are associated with physical impairments and biologic changes in older adults. Weight loss combined with exercise may reduce inflammation and improve physical functioning in overweight, sedentary, older adults. This study tested whether a weight loss program combined with moderate exercise could improve physical function in obese, older adult women. Participants (N = 34) were generally healthy, obese, older adult women (age range 55-79 years) with mild to moderate physical impairments (ie, functional limitations). Participants were randomly assigned to one of two groups for 24 weeks: (i) weight loss plus exercise (WL+E; n = 17; mean age = 63.7 years [4.5]) or (ii) educational control (n = 17; mean age = 63.7 [6.7]). In the WL+E group, participants attended a group-based weight management session plus three supervised exercise sessions within their community each week. During exercise sessions, participants engaged in brisk walking and lower-body resistance training of moderate intensity. Participants in the educational control group attended monthly health education lectures on topics relevant to older adults. Outcomes were: (i) body weight, (ii) walking speed (assessed by 400-meter walk test), (iii) the Short Physical Performance Battery (SPPB), and (iv) knee extension isokinetic strength. Participants randomized to the WL+E group lost significantly more weight than participants in the educational control group (5.95 [0.992] vs 0.23 [0.99] kg; P walking speed of participants in the WL+E group significantly increased compared with that of the control group (reduction in time on the 400-meter walk test = 44 seconds; P moderate caloric restriction plus moderate exercise can produce significant weight loss and improve physical function while maintaining muscle strength in obese, older adult women with mild to moderate physical impairments.

    Weight management through the childbearing years is important, yet few women have access to efficacious weight loss programs. Online social network-delivered programs may increase reach and thus impact. The aim of this study was to gauge interest in a Twitter-based weight loss intervention among women of childbearing age and the feasibility of recruitment via Twitter. We recruited English-speaking women aged 18-45 years (N = 63) from Twitter to complete an anonymous online survey including open-ended questions about program advantages and concerns. Forty percent of participants were obese and 83 % were trying to lose weight. Eighty-one percent were interested in a Twitter-delivered weight loss program. Interest was high in all subgroups (62-100 %). Participants (59 %) cited program advantages, including convenience, support/accountability, and privacy. Concerns (59 %) included questions about privacy, support/accountability, engagement, efficacy, and technology barriers. Research is needed to develop and evaluate social media-delivered interventions, and to develop methods for recruiting participants directly from Twitter.

    To evaluate a pharmacist-led weight loss program based on the general requirements set forth by the Centers for Medicare & Medicaid Services' (CMS) Decision Memo for Intensive Behavioral Therapy for Obesity. Onsite Walgreens pharmacy located inside the main administration building of Maricopa County in downtown Phoenix, AZ. A prevention and wellness behavioral therapy weight loss program was developed for patients of the Maricopa County on-site Walgreens. Current pharmacy patients were recruited to attend 14 one-on-one, pharmacist-led, face-to-face behavioral therapy sessions during a 6-month period that addressed diet, exercise, and nutrition. Interactive PowerPoint presentations were used throughout the sessions. The primary outcome was mean weight loss from baseline to the end of the study. Secondary outcomes included changes in body composition, changes in nutritional intake, and participant satisfaction. Of 12 enrolled participants, 11 (92%) completed the program. The mean weight loss from baseline to the end of the program was 5 kg (P <0.001), representing an average 4.5% weight loss. There was a statistically significant decrease in body mass index (BMI), waist circumference, and percent visceral fat from baseline to the end of the study; however, the increase in percent muscle mass, decrease in percent body fat, and change in nutrition intake was not statistically significant. Overall, the participants rated the program highly. Pharmacists are accessible health care providers who can effectively provide intensive behavioral therapy for obesity in a manner consistent with the CMS guidelines.

    Full Text Available The appropriate choice of input-output weights is necessary to have a successful DEA model. Generally, if the number of DMUs i.e., n, is less than number of inputs and outputs i.e., m+s, then many of DMUs are introduced as efficient then the discrimination between DMUs is not possible. Besides, DEA models are free to choose the best weights. For resolving the problems that are resulted from freedom of weights, some constraints are set on the input-output weights. Symmetric weight constraints are a kind of weight constrains. In this paper, we represent a new model based on a multi-criterion data envelopment analysis (MCDEA are developed to moderate the homogeneity of weights distribution by using symmetric weight constrains.Consequently, we show that the improvement of the dispersal of unrealistic input-output weights and the increasing discrimination power for our suggested models. Finally, as an application of the new model, we use this model to evaluate and ranking guilan selected hospitals.

    Length-based dosing systems reduce errors associated with resuscitation drug dosing. Obese and thin children of the same length are dosed the same despite their different weights. Length (height) and weight were measured in children after a body habitus icon assignment. Within each body habitus group, regression analysis was performed to generate a weight-estimation formula using body habitus and length (BHL). This BHL method was compared to the Broselow tape (BT). Height and weight data were plotted to obtain visual scattergrams. Logarithmic regression yielded higher correlation coefficients than standard linear regression. Within body habitus groups, BHL epinephrine dose estimates were more accurate than BT dose estimates using 0.01 mg/kg as a dosing standard. Adding body habitus information to the patient's length results in a more accurate weight estimate than length alone in children. The accuracy improvement is greater in children 3 years and older as compared to younger children.

    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

    The operational oceanography has been engaged in the development of new acquisition, transmission and assimilation systems in order to have the widest possible coverage of real time informations, reflecting the guidelines of the World Meteorological Organization (WMO) and of the Intergovernmental Oceanographic Commission (IOC). Physical and biological processes of marine ecosystems have a high spatial and temporal variability, whose study is possible only through high resolution and synoptic observations. More than for the physical variables, the biological ones have to be observed in situ. Especially in the mid-high latitudes, a deep observation of the water column is needed, because of the typical distribution of phytoplankton's biomass (Mann and Lazier, 1991). In the last times an extensive use of XBT was performed in order to provide near real time analysis of the ocean temperature, but there is still a lack in the biomass estimation. T-FLAP technology (Temperature and Fluorescence LAunchable Probe - Marcelli et al. 2007) was designed to answer to the claim of a cost effective temperature and fluorescence autonomous probe, to be used on ships of opportunity for the Voluntary Observing Ship Program (VOS). During the last three years the probe was upgraded and improved both in materials and in measure sensitivity. New LEDs were mounted to increase the radiant power of the excitation source.. In order to evaluate the red filter efficiency to detect fluorescence chlorophyll a emission wavelengths, transmittance of new available filters in the range 682-685 nm was calculated. In vivo fluorescence spectra of each filter were also performed on samples from Chlorella sp. cultures, to assess the percentage of the fluorescence emission peak transmitted by the filters. A multiple system was designed and realized for a high accuracy dynamic calibration of the probes.

    2017-07-15

    The obesity epidemic is a critical public health threat facing the USA. With the advent of American Evangelical Protestant (AEP) weight loss guides and narratives, AEP churches could potentially aid public health agencies in combatting obesity, and some scholars have called for investment in partnerships between public health agencies and religious institutions. This paper examines the theological and social underpinnings of AEP weight loss programs and considers the potential benefits and risks of public health partnerships with AEP churches to combat obesity. While AEP churches may be successful at empowering people to lose weight, AEP weight loss also carries several risks. These risks include reinforcing gendered bodily norms, stigmatizing both overweight bodies and unhealthy behaviors deemed to be sinful (for example, overeating), and failing to acknowledge social factors that promote obesity. These risks must be assessed and minimized to create appropriate public health weight loss partnerships with AEP communities.

    Full Text Available Objective: Telephone-based weight loss programs are offered as an alternative to face-to-face obesity treatments, but data on the effectiveness regarding weight loss are limited. Therefore, we evaluated a telephone-based lifestyle program in a real-world setting. Methods: The telephone-based intervention consists of regular phone calls providing individualized lifestyle recommendations, and delivery of printed materials. Anthropometric and metabolic data are collected by general practitioners or are self-reported. Results: Baseline data were available from 398 participants (61% men; weight 103.12 ± 14.21 kg; BMI 33.38 ± 2.83 kg/m2 and 1-year data from 258 (65% participants. In the completers, mean weight change was -4.25 ± 5.18 kg (p Conclusions: The telephone-based lifestyle program results in a moderate weight loss after 12 months, which may be comparable to face-to-face interventions. Telephone-based weight loss support is independent of time and location and represents a tool which is also accepted by men.

    The role of physical activity and the joint effect with sleep duration on insulin sensitivity (IS) during energy restriction followed by weight maintenance were determined. One hundred and two subjects (28 males) (mean ± SD age: 40 ± 9 years; BMI: 31.9 ± 3.0 kg/m(2) ) followed a very-low-energy diet for 8 weeks, followed by a 44-week period of weight maintenance. Body composition (three-compartment model based on body weight, total body water, and body volume), physical activity (accelerometry), sleep (questionnaire, Epworth Sleepiness Scale), and fasting plasma insulin and glucose concentrations were assessed before the diet and at 8, 20, and 52 weeks after the start. Compared to baseline, IS was improved significantly after 8 weeks (P weight loss percentage and change in physical activity counts. Maintaining daily physical activity during energy restriction is as important as weight loss itself in the improvement of IS; there was no additional effect of change in sleep duration. During weight maintenance, improved IS is maintained better if physical activity returns to baseline or higher. © 2016 The Obesity Society.

    Susceptibility to obesity is associated with a notable inter-individual variation. The aim of the present study was to compare the effectiveness of sleeve gastrectomy (SG) on weight loss and metabolic profile in obesity-prone (OP) rats vs animals that are non-susceptible to obesity (NSO). Young male Wistar rats (n = 101) were put in a diet-induced obesity (DIO) programme with ad libitum access to a high-fed diet (HFD) during 12 months. Body weight and food intake were regularly registered. Thereafter, rats were ranked by final body weight to identify the obesity-prone (OP) (n = 13) and non-susceptible to obesity (NSO) (n = 14) animals. OP and NSO rats were submitted to surgical interventions (sham operation, SG and pair-fed to the amount of food eaten by sleeve-gastrectomized rats). Body weight, food intake, energy expenditure, body temperature, fat pads weight, and metabolic profiling were analysed 4 weeks after surgical or dietary interventions. SG in both OP and NSO rats decreased body weight as compared to sham and pair-fed groups (P weight loss achieved in sleeve-gastrectomized OP and NSO rats was higher than that of pair-fed ones (P obesity-prone rats also benefit from surgery responding effectively to SG, as evidenced by the significant body weight reduction and the metabolic profile improvement.

    We compared the effect on weight regain of behaviour modification consisting of either a gourmet cooking course or neurolinguistic programming (NLP) therapy. Fifty-six overweight and obese subjects participated. The first step was a 12-week weight loss program. Participants achieving at least 8% weight loss were randomized to five months of either NLP therapy or a course in gourmet cooking. Follow-up occurred after two and three years. Forty-nine participants lost at least 8% of their initial body weight and were randomized to the next step. The NLP group lost an additional 1.8 kg and the cooking group lost 0.2 kg during the five months of weight maintenance (NS). The dropout rate in the cooking group was 4%, compared with 26% in the NLP group (p=0.04). There was no difference in weight maintenance after two and three years of follow-up. In conclusion, weight loss in overweight and obese participants was maintained equally efficiently with a healthy cooking course or NLP therapy, but the dropout rate was lower during the active cooking treatment.

  16. Obesity weight management and bariatric surgery case management programs: a review of literature.

    2010-01-01

    The proportion of Americans with clinically severe obesity has vast implications for the nation's healthcare system since this population have twice as many chronic medical conditions as people with normal weight. Through the use of review of literature, this article (a) describes the types of weight loss programs; (b) reviews the results from studies on effectiveness of bariatric surgery; and (c) identifies recommendations for obesity and bariatric surgery case management programs. Disease management companies appear to be concentrating on general weight loss strategies associated with wellness and other condition-specific disease management products, whereas larger national healthcare companies with at-risk and insurance products offer specific bariatric surgery management products. Case management programs within healthcare systems, health management organizations, and insurance companies are frequently faced with the management of individuals with morbid obesity and, increasingly, those who are requesting or have undergone bariatric surgery. Research shows that morbid obesity is a disease that remains generally unresponsive to diet and drug therapy but appears to respond well to bariatric surgery. Research findings suggest that surgical treatment is more effective than pharmacological treatment of weight loss and the control of some comorbidities associated with obesity. The number of Americans having weight loss surgery increased by 804% between 1998 and 2004, which appears to be a driver for the recent development of obesity disease management and bariatric surgery case management programs. Although the immaturity and lack of studies citing outcomes of obesity disease and case management programs limit the identification of best practices based on outcomes, emerging practices can be identified and recommendations for case management can be formulated. In addition to primary prevention and treatment programs for obesity, this article describes program

    This study was conducted to evaluate the effects of a body weight control program with supplementation of sea tangle (20 g/day) on 22 female college students. The contents of the program for 8 weeks contained diet therapy, exercise and behavioral modification through nutrition education. Body composition, dietary habit scores, serum lipid profiles, daily nutrient intakes and the quality of life were assessed at the beginning and at the end of the program. Average age of subjects and height were 20.8 years and 161.9 cm, respectively. After 8 weeks, there were significant reductions in body weight, body fat mass, percent body fat, waist-hip ratio and BMI. The dietary habit score such as a balanced diet, regularity of mealtime, overeating, eating while watching TV or using the computer and eating salty food were increased significantly. Serum lipid levels such as total cholesterol level, LDL-cholesterol level and triglyceride level were decreased but not significantly. There were decreases in intake of energy, protein and fat and increases in intakes of dietary fiber, folic acid, calcium and potassium from the beginning to the end of the program. There were significant improvements on subcomponents of quality of life; physical functioning, general-health and vitality. The limitation of this study was the fact that there was no control group, but an overall evaluation suggests the 8-week body weight control program consisting of diet therapy, exercise and behavioral modification with supplementation of sea tangle would be helpful to improve the body composition, dietary habits, daily nutrient intakes and quality of life in Korean female college students.

    While commercial dietary weight-loss programs typically advise exercise, few provide actual programing. The goal of this study was to compare the Curves Complete 90-day Challenge (CC, n = 29), which incorporates exercising and diet, to programs advocating exercise (Weight Watchers Points Plus (WW, n = 29), Jenny Craig At Home (JC, n = 27), and Nutrisystem Advance Select (NS, n = 28)) or control (n = 20) on metabolic syndrome (MetS) and weight loss. We randomized 133 sedentary, overweight women (age, 47 ± 11 years; body mass, 86 ± 14 kg; body mass index, 35 ± 6 kg/m2) into respective treatment groups for 12 weeks. Data were analyzed using chi square and general linear models adjusted for age and respective baseline measures. Data are means ± SD or mean change ± 95% confidence intervals (CIs). We observed a significant trend for a reduction in energy intake for all treatment groups and significant weight loss for all groups except control: CC (-4.32 kg; 95% CI, -5.75, -2.88), WW (-4.31 kg; 95% CI, -5.82, -2.96), JC (-5.34 kg; 95% CI, -6.86, -3.90), NS (-5.03 kg; 95% CI, -6.49, -3.56), and control (0.16 kg, 95% CI, -1.56, 1.89). Reduced MetS prevalence was observed at follow-up for CC (35% vs. 14%, adjusted standardized residuals (adjres.) = 3.1), but not WW (31% vs. 28% adjres. = 0.5), JC (37% vs. 42%, adjres. = -0.7), NS (39% vs. 50% adjres. = -1.5), or control (45% vs. 55% adjres. = -1.7). While all groups improved relative fitness (mL·kg-1·min-1) because of weight loss, only the CC group improved absolute fitness (L/min). In conclusion, commercial programs offering concurrent diet and exercise programming appear to offer greater improvements in MetS prevalence and cardiovascular function after 12 weeks of intervention.

    The Internet holds promise for the delivery of evidence-based weight loss treatment to underserved populations. However, most studies do not reflect the more naturalistic and common ad libitum, or freely at will, use of the Internet. Randomized clinical trials, for example, typically include at least some direct contact with participants and often have restrictive selection criteria. There is a paucity of research examining utilization patterns of online weight loss programs, particularly in the rapidly expanding direct-to-consumer arena. To examine self-reported characteristics (age, body mass index [BMI], gender), behaviors, and Internet site utilization patterns of a sample of users of a direct-to-consumer ad libitum Internet weight loss program. This study is based on analysis of archival data from the initial 15 weeks of an ongoing, free, evidence-based, direct-to-consumer Internet weight loss program, the Healthy Weight Center, which included standard information about nutrition, fitness, and behavioral strategies; monitoring tools; and moderated support group message boards. Participants encountered the program through self-directed Internet searches and anonymously registered to utilize the site. Self-reported user characteristics and electronically tracked utilization data were extracted from existing program data, compiled, and examined. Pearson correlations were computed to examine the association of program utilization with age and BMI. One-way analysis of variance (ANOVA) was used for gender comparisons. We examined data from the first 204 adult users of the program who were classified as either overweight (BMI 25 to or = 30 kg/m(2)). The mean age of participants was 42.0 years (SD 11.7), 81.9% (167/204) were women, and mean BMI was 32.01 kg/m(2) (SD 6.26). The percent of participants who used program tools was as follows: 13.7%, meal planner; 10.8%, nutrition lookup: 17.6%, activity log; 14.2%, journal; and 22.1%, weight tracker. Participants also

    It has been suggested that weight reduction decreases the frequency of urinary incontinence (UI) episodes. However, it is not known if this improvement is associated with anatomical changes in the pelvis. The aim of this study was to investigate the effects of weight loss on UI episodes and pelvic floor anatomy. Three hundred seventy-eight overweight/obese women were randomly allocated either to behavioral weight loss or to structured education programs. The patients were evaluated by voiding diary, Pelvic Floor Distress Inventory (PFDI), and Pelvic Organ Prolapse Quantification (POP-Q) system at baseline and after 6 months. The women in the intervention group had a mean weight loss of 9.4 %, whereas the weight in the control group remained almost the same (P pelvic floor symptoms. However, there are little to no changes in the parameters of the POP-Q system with weight reduction.

  2. Impact of Body Composition on Physical Performance Tasks in Older Obese Women Undergoing a Moderate Weight Loss Program.

    2013-01-01

    Although obesity is a recognized risk factor for impaired physical function in older adults, there is still debate on whether older obese adults should undergo intentional weight loss due to concern of loss in lean body mass, including appendicular lean soft tissue mass. This may put them at risk for worsening muscle strength and mobility. Therefore, the purpose of this study was to examine the effect of a weight loss intervention on body composition and physical function in obese older women. Women were randomized into either a weight stable (WS) (n=20) or an intensive weight loss (WL) (n=26) group. The study setting was at a university research facility. Women (age, 67.8±1.3 yrs; BMI, 34.9 (0.7) kg/m2; mean±standard error of the mean) were recruited. The WL intervention was for 6 months and included moderate dietary energy restriction and aerobic and strength exercise training. Variables were obtained at baseline and 6-months and included body weight, dual energy x-ray absorptiometry (DXA), 6-minute walk distance, stair climb time, and concentric knee extension muscular strength. Estimated marginal means (SEM) for weight loss at 6-months was -8.5 (0.9)% for WL and +0.7 (1.0)% for WS. There was a significant loss of body fat mass, lean body mass, appendicular lean soft tissue mass, relative muscle mass, and skeletal muscle index for WL vs. WS at 6-months. However, improvements for WL vs. WS were seen in 6-minute walk distance and stair climb time, and trends for improved relative strength and leg muscle quality. Change in body fat mass was positively related to improved physical function and muscle strength and quality. These results further support the use of a sound intentional weight loss program incorporating moderate dietary energy restriction and exercise training in older obese women to improve physical function. Although lean soft tissue mass was lost, over the 6-month program there was no deleterious effect on muscle strength or muscle quality.

    Obesity in adolescents is associated with metabolic risk factors for type 2 diabetes, particularly insulin resistance and excessive accumulation of intrahepatic triglyceride (IHTG). The purpose of this study was to evaluate the effect of moderate weight loss on IHTG content and insulin sensitivity in obese adolescents who had normal oral glucose tolerance. Insulin sensitivity, assessed by using the hyperinsulinemic-euglycemic clamp technique in conjunction with stable isotopically labeled tracer infusion, and IHTG content, assessed by using magnetic resonance spectroscopy, were evaluated in eight obese adolescents (BMI >or=95th percentile for age and sex; age 15.3 +/- 0.6 years) before and after moderate diet-induced weight loss (8.2 +/- 2.0% of initial body weight). Weight loss caused a 61.6 +/- 8.5% decrease in IHTG content (P = 0.01), and improved both hepatic (56 +/- 18% increase in hepatic insulin sensitivity index, P = 0.01) and skeletal muscle (97 +/- 45% increase in insulin-mediated glucose disposal, P = 0.01) insulin sensitivity. Moderate diet-induced weight loss decreases IHTG content and improves insulin sensitivity in the liver and skeletal muscle in obese adolescents who have normal glucose tolerance. These results support the benefits of weight loss therapy in obese adolescents who do not have evidence of obesity-related metabolic complications during a standard medical evaluation.

    To investigate the effects of the home exercise therapy performed after at least four years postoperatively on skeletal muscle strength and functionality in patients with total knee arthroplasty (TKA). Sixty patients (age; 69.66±7.53, weight; 81.56±14.43 kg, 10 male, 50 female) followed up four or more years were randomly divided into two groups. An 8-week exercise program was designed for bilateral TKA patients. While the patients in one group were assigned to weighted exercise group, the patients in the other group were assigned to non-weighted exercise group. The primary outcome was the isometric muscle strength of quadriceps femoris (QF) and hamstring muscles assessed by Hand-Held Dynamometer. The secondary outcomes were the pain level, 30s sit-to-stand test, 10 m walk test, range of motion, and the knee function score of the Hospital for Special Surgery. The assessments were performed before and after the treatment. After treatment, significant differences were found in all evaluation parameters (except rest pain and range of motion) in favour of the weighted group. QF muscle strength changes (kg); weighted group: 1.99±1.70, non-weighted group: 0.51±1.14 (p=0.000), 30s sit-to-stand test changes (repetitions); weighted group: 3.66±2.23, non-weighted group: 1.70±1.95 (p=0.000), 10 m walk test changes (seconds); weighted group: -2.60±1.30, non-weighted group: -0.83±3.51 (p=0.000). Home exercise programs applied to TKA patients after at least four years postoperatively was effective in increasing muscle strength, decreasing severity of pain, and improving functional activities. The improvements were significantly greater in weighted compared with the non-weighted exercise group. Copyright © 2016 Elsevier Ireland Ltd. All rights reserved.

    Full Text Available BACKGROUND: The prevalence of obesity is rising. Obesity can lead to cardiovascular and ventilatory complications through multiple mechanisms. Cardiac and pulmonary function in asymptomatic subjects and the effect of structured dietary programs on cardiac and pulmonary function is unclear. OBJECTIVE: To determine lung and cardiac function in asymptomatic obese adults and to evaluate whether weight loss positively affects functional parameters. METHODS: We prospectively evaluated bodyplethysmographic and echocardiographic data in asymptomatic subjects undergoing a structured one-year weight reduction program. RESULTS: 74 subjects (32 male, 42 female; mean age 42±12 years with an average BMI 42.5±7.9, body weight 123.7±24.9 kg were enrolled. Body weight correlated negatively with vital capacity (R = -0.42, p<0.001, FEV1 (R = -0.497, p<0.001 and positively with P 0.1 (R = 0.32, p = 0.02 and myocardial mass (R = 0.419, p = 0.002. After 4 months the study subjects had significantly reduced their body weight (-26.0±11.8 kg and BMI (-8.9±3.8 associated with a significant improvement of lung function (absolute changes: vital capacity +5.5±7.5% pred., p<0.001; FEV1+9.8±8.3% pred., p<0.001, ITGV+16.4±16.0% pred., p<0.001, SR tot -17.4±41.5% pred., p<0.01. Moreover, P0.1/Pimax decreased to 47.7% (p<0.01 indicating a decreased respiratory load. The change of FEV1 correlated significantly with the change of body weight (R = -0.31, p = 0.03.

    2008-09-01

    Every year, employers around the country evaluate their company benefits package in the hopes of finding a solution to the ever-rising cost of health insurance premiums. For many business executives, the only logical choice is to pass along those costs to the employee. As an employer, our goal in Delaware has always been to come up with innovative solutions to drive down the cost of health insurance premiums while encouraging our employees to take responsibility for their own health and wellness by living a healthy and active lifestyle, and provide them with the necessary tools. The DelaWELL program (N = 68,000) was launched in 2007, after being tested in initial (N = 100) and expanded (N = 1500) pilot programs from 2004 to 2006 in which 3 similar groups were compared before and after the pilot. Employee health risk assessment, education, and incentives provided employees the necessary tools we had assumed would help them make healthier lifestyle choices. In the first pilot, fewer emergency department visits and lower blood pressure levels resulted in direct savings of more than $62,000. In the expanded pilot, in all 3 groups blood pressure was significantly reduced (P employees participating in DelaWELL had a combined weight loss of 5162 lb. Decision makers in the State of Delaware have come up with an innovative solution to controlling costs while offering employees an attractive benefits package. The savings from its employee benefit program have allowed the state to pass along the savings to employees by maintaining employee-paid health insurance contributions at the same level for the past 3 years. DelaWELL has already confirmed our motto, "Although it may seem an unusual business investment to pay for healthcare before the need arises, in Delaware we concluded that this makes perfect sense." This promising approach to improving health and reducing healthcare costs could potentially be applied to other employer groups.

    Obesity is thought to affect quality of life, but limited objective data exist to support this supposition. The current study aim was to use a questionnaire to determine health-related quality of life (HRQOL) both before and after weight loss, in obese client-owned dogs. Fifty obese dogs were included, and represented a variety of breeds and genders. Prior to weight loss, owners were asked to complete a validated standardised questionnaire to determine HRQOL. Thirty of the dogs successfully completed their weight loss programme and reached target, and owners then completed a follow-up questionnaire. The completed questionnaire responses were transformed to scores corresponding to each of four factors (vitality, emotional disturbance, anxiety and pain), and scored on a scale of 0-6. Changes in the scores were used to explore the sensitivity of the questionnaire, and scores were correlated with responses to direct questions about quality of life and pain, as well as weight loss. Dogs that failed to complete their weight loss programme had lower vitality and higher emotional disturbance scores than those successfully losing weight (P=0.03 for both). In the 30 dogs that completed, weight loss led to an increased vitality score (Panxiety (P=0.09). The change in vitality score was positively associated with percentage weight loss (r(P)=0.43, P=0.02) and percentage body fat loss (r(P)=0.39, P=0.03). These results indicate demonstrable improvement in HRQOL for obese dogs that successfully lose weight. Copyright © 2011 Elsevier Ltd. All rights reserved.

    Background Intermittent severe energy restriction is popular for weight management. To investigate whether intermittent moderate energy restriction may improve this approach by enhancing weight loss efficiency, we conducted a study in mice, where energy intake can be controlled. Methods Male C57/Bl6 mice that had been rendered obese by an ad libitum diet high in fat and sugar for 22 weeks were then fed one of two energy-restricted normal chow diets for a 12-week weight loss phase. The continuous diet (CD) provided 82% of the energy intake of age-matched ad libitum chow-fed controls. The intermittent diet (ID) provided cycles of 82% of control intake for 5–6 consecutive days, and ad libitum intake for 1–3 days. Weight loss efficiency during this phase was calculated as (total weight change) ÷ [(total energy intake of mice on CD or ID)–(total average energy intake of controls)]. Subsets of mice then underwent a 3-week weight regain phase involving ad libitum re-feeding. Results Mice on the ID showed transient hyperphagia relative to controls during each 1–3-day ad libitum feeding period, and overall ate significantly more than CD mice (91.1±1.0 versus 82.2±0.5% of control intake respectively, n = 10, Pweight loss or weight regain phases with respect to body weight, fat mass, circulating glucose or insulin concentrations, or the insulin resistance index. Weight loss efficiency was significantly greater with ID than with CD (0.042±0.007 versus 0.018±0.001 g/kJ, n = 10, Pweight loss relative to energy deficit in mice. PMID:26784324

    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.

    An increasing prevalence of obesity all over the world reflects a lack of effective measures in both prevention and treatment of obesity. Obesity as a disease has been underestimated by the lay-public as well as health care providers. However, obesity represents a substantial health problem associated with a decreased quality of life. Obesity is linked to numerous chronic diseases (cardiovascular diseases, diabetes, hyperlipidemia, gout, osteoarthritis, gall-stones, and bowel, breast and genitourinary cancers) that lead to premature disability and mortality. Health risks increase with a body mass index (BMI) over 25 in individuals 19-35 years of age and with a BMI over 27 in those 35 years of age and older. Health risks also increase with an excess accumulation of visceral fat manifested as an increase in waist circumference (> 100 cm) or in waist to hip ratio (> 0.85 for females and > 1.00 for males). According to studies carried out in different countries current economic costs of obesity represent 5-8% of all direct health costs. In contrast, effective treatment of obesity results in a substantial decrease in expenditures associated with pharmacotherapy of hypertension, diabetes, hyperlipidemia and osteoarthritis. Both scientists and clinicians involved in obesity research and treatment recommend to introduce the long-term weight management programs focussing more on the overall health of the participants than the weight loss per se. Therefore, it will be necessary to establish new realistic goals in the obesity management that reflect reasonable weights and recently experienced beneficial health effects of modest (5-10%) weight loss. Comprehensive obesity treatment consisting of low fat diet, exercise, behavioral modification, drug therapy and surgical procedures requires differentiated weight management programs modified according to the degree and type of obesity as well as to current health complications present.

    BACKGROUND: The objective was to investigate in a group of obese subjects the course in skeletal muscle phospholipid (SMPL) fatty acids (FA) during a 24-weeks weight maintenance program, which was preceded by a successful very low calorie dietary intervention (VLCD). Special focus was addressed...... to SMPL omega-3 FA, which is a lipid entity that influences insulin action. METHODS: Nine obese subjects (BMI = 35.7 +/- 1.0 kg/m(2)), who had completed an 8 weeks VLCD (weight-loss = -9.7 +/- 1.6 kg, P ...-maintenance program five subjects received the pancreas lipase inhibitor Orlistat 120 mg t.i.d. versus placebo. RESULTS: HOMA-IR and HbA1c stabilized and SMPL total omega-3 FA, docosahexaenoic acid and ratio of n-3/n-6 polyunsaturated FA increased by 24% (P

    Full Text Available Many tilapia (Oreochromis spp. farmers produce all-male populations because of the superior growth rate of males compared to females. To investigate differences in body weight at harvest of males and females among different tilapia strains, we analyzed data from 62,787 individuals collected from pedigreed breeding programs of O. niloticus (GIFT from Malaysia, the Abbassa line from Egypt, and the Akosombo line from Ghana, O. shiranus (the Bunda College-Domasi selection line, O. aureus (a selection line under development in Abbassa, Egypt, and a selection line from Israel and a synthetic selection line of Red tilapia under development in Jitra, Malaysia, derived from stock from Malaysia, Taiwan and Thailand (O. sp.. Mixed models were separately fitted to the data from each selection line. There was a significant sex effect in all strains (P < 0.001. A significant (P < 0.001 sex by generation interaction was observed in all strains (scale effect, not reversal of rankings, except Red tilapia and O. shiranus. Least squares means showed a large range in the magnitude of body weight differences between sexes across the seven strains. The largest percentage difference between females and males was in O. aureus from Egypt (female body weight was 52.2% that of males at harvest, whereas the smallest difference was observed in the GIFT strain of O. niloticus (female body weight 84.7% that of males. Female to male body weight percentages for Red tilapia, O. shiranus, Egypt O. niloticus, Israeli O. aureus and Ghana O. niloticus were 81.3, 81.0, 69.1, 61.7 and 61.0, respectively. We discuss the results in relation to the potential productivity improvements due to superior growth rates of all-male culture compared to mixed-sex culture in tilapia populations differing in the female to male body weight ratio.

    Purpose: Phosphorous metabolite ratios in human myocardium were determined by a combination of acquisition weighted CSI and a SLOOP evaluation and the results were compared to corresponding SLOOP experiments using standard CSI. Materials and Methods: 10 healthy subjects were examined at 1.5 T using both standard CSI and acquisition weighted CSI. Both experiments were performed with a similar acquisition time and the same spatial resolution. The PCr/ATP ratio was determined and the localization properties of both experiments were compared. Results: The PCr/ATP ratio of 2.2 ± 0.4 found for the experiment using acquisition weighted CSI was almost identical to the value of 2.0 ± 0.4 for standard CSI. The sensitivity and the localization properties improved in all subjects using SLOOP evaluation of the acquisition weighted sampling in comparison to the standard CSI acquisition with an average of 3% and 18%, respectively. Conclusion: The employment of acquisition weighting allows for a further improvement of the {sup 31}P SLOOP spectroscopy of the human heart. (orig.)

    Full Text Available Background: Adequate nutrient supply is essential for optimal postnatal growth in very low birth weight (VLBW, birth weight<1,500 g infants. Early growth may influence the risk of metabolic syndrome later in life. Objective: To evaluate growth and blood metabolic markers (adiponectin, leptin, and insulin-like growth factor-1 (IGF-1 in VLBW infants participating in a randomized nutritional intervention study. Design: Fifty VLBW infants were randomized to an enhanced nutrient supply or a standard nutrient supply. Thirty-seven infants were evaluated with growth measurements until 2 years corrected age (CA. Metabolic markers were measured at birth and 5 months CA. Results: Weight gain and head growth were different in the two groups from birth to 2 years CA (weight gain: pinteraction=0.006; head growth: pinteraction=0.002. The intervention group improved their growth z-scores after birth, whereas the control group had a pronounced decline, followed by an increase and caught up with the intervention group after discharge. At 5 months CA, adiponectin concentrations were higher in the intervention group and correlated with weight gain before term (r=0.35 and nutrient supply (0.35≤r≤0.45. Leptin concentrations correlated with weight gain after term and IGF-1 concentrations with length growth before and after term and head growth after term (0.36≤r≤0.53. Conclusion: Enhanced nutrient supply improved early postnatal growth and may have prevented rapid catch-up growth later in infancy. Adiponectin concentration at 5 months CA was higher in the intervention group and correlated positively with early weight gain and nutrient supply. Early nutrition and growth may affect metabolic markers in infancy.Clinical Trial Registration (ClinicalTrials.gov no.: NCT01103219

    Intermittent severe energy restriction is popular for weight management. To investigate whether intermittent moderate energy restriction may improve this approach by enhancing weight loss efficiency, we conducted a study in mice, where energy intake can be controlled. Male C57/Bl6 mice that had been rendered obese by an ad libitum diet high in fat and sugar for 22 weeks were then fed one of two energy-restricted normal chow diets for a 12-week weight loss phase. The continuous diet (CD) provided 82% of the energy intake of age-matched ad libitum chow-fed controls. The intermittent diet (ID) provided cycles of 82% of control intake for 5-6 consecutive days, and ad libitum intake for 1-3 days. Weight loss efficiency during this phase was calculated as (total weight change) ÷ [(total energy intake of mice on CD or ID)-(total average energy intake of controls)]. Subsets of mice then underwent a 3-week weight regain phase involving ad libitum re-feeding. Mice on the ID showed transient hyperphagia relative to controls during each 1-3-day ad libitum feeding period, and overall ate significantly more than CD mice (91.1±1.0 versus 82.2±0.5% of control intake respectively, n = 10, Pindex. Weight loss efficiency was significantly greater with ID than with CD (0.042±0.007 versus 0.018±0.001 g/kJ, n = 10, Penergy-restricted groups. Intermittent moderate energy restriction may offer an advantage over continuous moderate energy restriction, because it induces significantly greater weight loss relative to energy deficit in mice.

    Obesity and poor sleep are highly prevalent among Black women. We examined whether a weight gain prevention intervention improved sleep among Black women. We conducted a randomized trial comparing a 12-month weight gain prevention intervention that included self-monitoring through mobile technologies and phone coaching to usual care in community health centers. We measured sleep using the Medical Outcomes Study Sleep Scale at baseline, 12 months, and 18 months. The scale examines quantity of sleep, sleep disturbance, sleep adequacy, daytime somnolence, snoring, shortness of breath, and global sleep problems (sleep problem indices I and II). Participants (n = 184) were on average 35.4 years and obese (BMI 30.2 kg/m2); 74% made sleep duration was 6.4 (1.5) hours. Controlling for weight change and sleep medication, the intervention group reported greater improvements in sleep disturbance [-8.35 (-16.24, -0.45)] and sleep problems at 12 months: sleep problem index I [-8.35 (-16.24, -0.45)]; sleep problem index II [-8.35 (-16.24, -0.45)]. However, these findings did not persist at 18 months. Preventing weight gain may afford clinical benefit on improving sleep quality. The trial was registered with the ClinicalTrials.gov database (NCT00938535).

    Among women with hypertrophic breasts, the clear majority are overweight or obese. Owing to increased risk of complications, women with a body mass index (BMI) above 25 kg m -2 are precluded from reduction mammaplasty. The primary aim was to investigate if intensive weight loss could ready women with overweight for breast reduction surgery. Six women, all overweight [BMI 30.9 {28.5; 35.8} kg m -2 ] with symptomatic hypertrophy of the breast, were included a 12-week weight loss program. All women desired reduction mammaplasty and were motivated for preoperational weight loss. The first 8 weeks consisted of a formula-based diet supplying 800 kcal daily, in the subsequent 4 weeks regular foods were reintroduced increasing the intake to 1200 kcal daily. Five women completed the trial, and achieved a median (range) weight loss of 10.2 (6.5; 19) kg. Initial breast volume was 1100-2500 mL per breast, this was reduced by 300 (200; 500) mL after the intervention; equivalent to approximately 19%. Waist, hip, upper arm and thorax circumference were significantly reduced following weight loss. At end of study, all the women still suffered from symptomatic breast hypertrophy to substantiate reduction mammaplasty. Surgeries were performed 2 months thereafter. A 12-week intensive preoperative weight loss program enabled women with obesity for breast reduction surgery. Breast size was reduced proportionally more than total weight loss among women with hypertrophy. © 2017 World Obesity Federation.

    Clinical control is difficult to achieve in obese patients with asthma. Bariatric surgery has been recommended for weight loss and to improve asthma control; however, the benefits of nonsurgical interventions have been poorly investigated. To examine the effect of exercise training in a weight-loss program on asthma control, quality of life, inflammatory biomarkers, and lung function. Fifty-five obese patients with asthma were randomly assigned to either a weight-loss program plus exercise (WL + E group, n = 28) or a weight-loss program plus sham (WL + S group, n = 27), where the weight-loss program included nutrition (caloric restriction) and psychological therapies. The WL + E group incorporated aerobic and resistance muscle training, whereas the WL + S group incorporated breathing and stretching exercises. The primary outcome was clinical improvement in asthma control over 3 months. Secondary outcomes included quality of life, lung function, body composition, aerobic capacity, muscle strength, and inflammatory/antiinflammatory biomarkers. After 3 months, 51 patients were analyzed. Compared with the WL + S group, the WL + E group demonstrated improved clinical control scores (median [25th to 75th percentile], -0.7 [-1.3 to -0.3] vs. -0.3 [-0.9 to 0.4]; P = 0.01) and greater weight loss (mean ± SD, -6.8% ± 3.5 vs. -3.1% ± 2.6; P weight-loss program should be considered as a useful strategy for achieving clinical control of asthma in obese patients.

    'Fetal programming' is a newly emerging field that is revealing astounding insights into the prenatal origins of adult disease, including metabolic, endocrine, and cardiovascular pathophysiology. In the present study, we tested the hypothesis that rat pups conceived, gestated and born at 2-g have significantly reduced birth weights and increased adult body weights as compared to 1-g controls. Offspring were produced by mating young adult male and female rats that were adapted to 2-g centrifugation. Female rats underwent conception, pregnancy and birth at 2-g. Newborn pups in the 2-g condition were removed from the centrifuge and fostered to non-manipulated, newly parturient dams maintained at 1 -g. Comparisons were made with 1-g stationary controls, also crossfostered at birth. As compared to 1-g controls, birth weights of pups gestated and born at 2-g were significantly reduced. Pup body weights were significantly reduced until Postnatal day (P) 12. Beginning on P63, body weights of 2-g-gestated offspring exceeded those of 1-g controls by 7-10%. Thus, prenatal rearing at 2-g restricts neonatal growth and increases adult body weight. Collectively, these data support the hypothesis that 2-g centrifugation alters the intrauterine milieu, thereby inducing persistent changes in adult phenotype.

    We examined self-determination theory (SDT) and weight loss, and hypothesized that the Diabetes Prevention Program's (DPP) intervention would result in an increase in autonomous regulation of motivation (AR) in participants. Further, that those with higher AR, and those who perceived educators as supporting SDT-defined needs, would lose more weight. Support, Health Information, Nutrition and Exercise (SHINE) Study data (N = 257) were analyzed. SHINE was a randomized, controlled DPP translation trial (2-years, telephonic, primary care staff). Autonomous motivation in males increased significantly, while females showed no change. Males with high AR, but not females, lost more weight. However, the significance of these relationships varied over time. Participants who perceived educators as more supportive of psychological needs lost more weight (especially males). However, effect of support on weight loss was not mediated by AR change. Autonomous motivation and educator support are relevant to male weight loss. Future research might develop interventions to enhance autonomous motivation and educator support, and understand change pathways.

    Osteoarthritis (OA) is the most common chronic condition and principal cause of disability among older adults. The current obesity epidemic has contributed to this high prevalence rate. Fortunately both OA symptoms and obesity can be ameliorated through lifestyle modifications. Physical activity (PA) combined with weight management improves physical function among obese persons with knee OA but evidence-based interventions that combine PA and weight management are limited for this population. This paper describes a comparative effectiveness trial testing an evidence-based PA program for adults with lower extremity (LE) OA, Fit and Strong!, against an enhanced version that also addresses weight management based on the evidence-based Obesity Reduction Black Intervention Trial (ORBIT). Adult participants (n=400) with LE OA, age 60+, overweight/obese, and not meeting PA requirements of ≥ 150 min per week, are randomized to one of the two programs. Both 8-week interventions meet 3 times per week and include 60 min of strength, flexibility, and aerobic exercise instruction followed by 30 min of education/group discussion. The Fit and Strong! education sessions focus on using PA to manage OA; whereas Fit and Strong! Plus addresses PA and weight loss management strategies. Maintenance of behavior change is reinforced in both groups during months 3-24 through telephone calls and mailed newsletters. Outcomes are assessed at baseline, and 2, 6, 12, 18, and 24 months. Primary outcomes are dietary change at 2 months followed by weight loss at 6 months that is maintained at 24 months. Secondary outcomes assess PA, physical performance, and anxiety/depression.

    Prior studies show seven percent to nine percent of children demonstrate gaming behaviors that affect a child's ability to function (e.g., problem gaming), but none have examined the association between problem gaming and weight status. The objective of this study was to determine the prevalence of problem gaming among children enrolled in tertiary weight management programs. We administered a computer-based survey to a convenience sample of children aged 11-17 years enrolled in five geographically diverse pediatric weight management (PWM) programs in the COMPASS (Childhood Obesity Multi-Program Analysis and Study System) network. The survey included demographics, gaming characteristics, and a problem gaming assessment. The survey had 454 respondents representing a diverse cohort (53 percent females, 27 percent black, 24 percent Hispanic, 41 percent white) with mean age of 13.7 years. A total of 8.2 percent of respondents met criteria for problem gaming. Problem gamers were more likely to be white, male, play mature-rated games, and report daily play. Children in PWM programs reported problem gaming at the same rate as other pediatric populations. Screening for problem gaming provides an opportunity for pediatricians to address gaming behaviors that may affect the health of children with obesity who already are at risk for worsened health and quality of life.

    To examine changes in weight and related outcomes in response to a commercial weight loss program compared to a self-directed diet in adults with overweight or obesity. Participants were randomly assigned [stratified by body mass index (BMI) and age] to a commercial weight loss program (n = 38) or to a self-directed Dietary Approaches to Stop Hypertension (DASH) diet (n = 40) for a 16-week period. Daily energy intake goals were 1,500 kcal/d for men and 1,200 kcal/d for women, except for the first week of the commercial program (1,000 kcal/d). This study was registered at http://ClinicalTrials.gov (NCT03017443). Primarily Caucasian (71%) women (n = 61) and men (n = 17) from the greater metropolitan area of the city of Chicago, IL, USA. with a mean baseline BMI of 34.4 kg/m2, body weight of 95.7 kg, and age of 50.4 years. Data = mean (95% CI). At week 16, the commercial program group lost significantly more body weight [-5.9 (-7.5, -4.3) kg vs. -1.8 (-2.9, -0.8) kg; or -6.4 vs. -1.8% of initial body weight, respectively], fat mass [-4.4 (-5.7, -3.1) kg vs. -1.2 (-2.1, -0.4) kg] and total body circumference (chest + waist + hip + upper arm + thigh) [-16.9 (-21.5, -12.3) cm vs. -5.8 (-9.0, -2.6) cm] (p lost a clinically meaningful amount of weight, defined as ≥5% of initial body weight, at week 16 (58% vs. 13%, p weight loss and improvements in body composition/anthropometric parameters compared to a self-directed DASH diet over a 16-week period. Some important limitations were that no objective measurements of dietary intake or physical activity were collected to potentially ascertain the independent or combined effects of these components on weight loss (or lack thereof). Additionally, future research is warranted in order to understand the effects of this program, and similar programs, on longer term changes in body weight, in particular weight loss maintenance, as weight regain is common following the cessation

    This paper presents an effective approach for state estimation in power systems that include multi-terminal voltage source converter based high voltage direct current (VSC-MTDC), called improved adaptive weighting function method. The proposed approach is simplified in which the VSC-MTDC system is solved followed by the AC system. Because the new state estimation method only changes the weight and keeps the matrix dimension unchanged. Accurate and fast convergence of AC/DC system can be realized by adaptive weight function method. This method also provides the technical support for the simulation analysis and accurate regulation of AC/DC system. Both the oretical analysis and numerical tests verify practicability, validity and convergence of new method.

    Although obstructive sleep apnea (OSA) is strongly linked with obesity, both conditions have been associated with increased cardiovascular risk including glucose intolerance, dyslipidemia, and hypertension independent of one another. Weight loss is known to improve both cardiovascular risk and OSA severity. The aim of this study was to evaluate cardiovascular and metabolic changes, including compartment-specific fat loss in obese OSA subjects undergoing a weight loss program. Observational study. 93 men with moderate-severe OSA. 6-month open-label weight loss trial combining sibutramine (a serotonin and noradrenaline reuptake inhibitor) with a 600-kcal deficit diet and exercise. At baseline and following 6 months of weight loss, OSA was assessed together with CT-quantified intraabdominal and liver fat and markers of metabolic and cardiovascular function. At 6 months, weight loss and improvements in OSA were accompanied by improved insulin resistance (HOMA), increased HDL cholesterol, and reduced total cholesterol/HDL ratio. There were also reductions in measures of visceral and subcutaneous abdominal fat and liver fat. Reductions in liver fat and sleep time spent below 90% oxyhemoglobin saturation partly explained the improvement in HOMA (R2 = 0.18). In contrast, arterial stiffness (aortic augmentation index), heart rate, blood pressure, and total cholesterol did not change. Weight loss with sibutramine was associated with improvements in metabolic and body composition risk factors but not blood pressure or arterial stiffness. Improved insulin resistance was partly associated with reductions in liver fat and hypoxemia associated with sleep apnea.

    Competing activities and projects can interfere with implementing new knowledge and approaches. The purpose, therefore, was to investigate processes and impact related to implementing two concurrent quality initiatives in a Swedish hospital. These were a regionally initiated, system-wide organizational learning programme called the Dynamic and Viable Organization (DVO) and a national initiative on stopping healthcare-associated and hospital-acquired infections (SHAI). Both undertakings aspired to increase staff competence in systematic improvement approaches. Multiple methods were applied including surveys, observations, interviews, process diaries, documents and organizational measurements. Respondents were unit managers, change facilitators and improvement team members. Even though both initiatives shared the same improvement approach, there was no strong indication that they were strategically combined to benefit each other. The initiatives existed side by side with some coordination and some conflict. Despite absent management strategies to utilize the national SHAI initiative, positive developments in QI culture and communication were reported. The current study illustrates the inherent difficulties coordinating change initiatives, even in favourable circumstances. This article addresses the lesser studied but common situation of coinciding and competing projects in organizations.

  5. TCF7L2 polymorphism, weight loss and proinsulin:insulin ratio in the diabetes prevention program.

    Directory of Open Access Journals (Sweden)

    Jeanne M McCaffery

    Full Text Available TCF7L2 variants have been associated with type 2 diabetes, body mass index (BMI, and deficits in proinsulin processing and insulin secretion. Here we sought to test whether these effects were apparent in high-risk individuals and modify treatment responses.We examined the potential role of the TCF7L2 rs7903146 variant in predicting resistance to weight loss or a lack of improvement of proinsulin processing during 2.5-years of follow-up participants (N = 2,994 from the Diabetes Prevention Program (DPP, a randomized controlled trial designed to prevent or delay diabetes in high-risk adults.We observed no difference in the degree of weight loss by rs7903146 genotypes. However, the T allele (conferring higher risk of diabetes at rs7903146 was associated with higher fasting proinsulin at baseline (P<0.001, higher baseline proinsulin:insulin ratio (p<0.0001 and increased proinsulin:insulin ratio over a median of 2.5 years of follow-up (P = 0.003. Effects were comparable across treatment arms.The combination of a lack of impact of the TCF7L2 genotypes on the ability to lose weight, but the presence of a consistent effect on the proinsulin:insulin ratio over the course of DPP, suggests that high-risk genotype carriers at this locus can successfully lose weight to counter diabetes risk despite persistent deficits in insulin production.

  6. Improved Neural Networks with Random Weights for Short-Term Load Forecasting

    Lang, Kun; Zhang, Mingyuan; Yuan, Yongbo

    2015-01-01

    An effective forecasting model for short-term load plays a significant role in promoting the management efficiency of an electric power system. This paper proposes a new forecasting model based on the improved neural networks with random weights (INNRW). The key is to introduce a weighting technique to the inputs of the model and use a novel neural network to forecast the daily maximum load. Eight factors are selected as the inputs. A mutual information weighting algorithm is then used to allocate different weights to the inputs. The neural networks with random weights and kernels (KNNRW) is applied to approximate the nonlinear function between the selected inputs and the daily maximum load due to the fast learning speed and good generalization performance. In the application of the daily load in Dalian, the result of the proposed INNRW is compared with several previously developed forecasting models. The simulation experiment shows that the proposed model performs the best overall in short-term load forecasting. PMID:26629825

    The product specification of the Continuous Hot Dip Galvanizing Line (CGL) changes and varies constantly with different customers' requirements, especially in the zinc coating weight which is from 30 to 150 g/m{sup 2} on each side. Since the coating weight of zinc changes often, it is very important to reduce time spent in the transfer of target values changed for low production cost and yield loss. The No.2 CGL in China Steel Corporation (CSC) has improved the control of the air knife which is designed by Siemens VAI. CSC proposed an experiment design which is an L{sub 9}(3{sup 4}) orthogonal array to find the relations between zinc coating weight and the process parameters, such as the line speed, air pressure, gap of air knife and air knife position. A non-linear regression formula was derived from the experimental results and applied in the mathematical model. A new air knife feedforward control system, which is coupled with the regression formula, the air knife control system and the process computer, is implemented into the line. The practical plant operation results have been presented to show the transfer time is obviously shortened while zinc coating weight target changing and the product rejected ratio caused by zinc coating weight out of specification is significantly reduced from 0.5% to 0.15%.

    Full Text Available Overweight and obesity is prevalent among women of reproductive age (42% BMI > 25 kg/m2 and parity is associated with risk of weight gain. Weight gain greater than that recommended by the Institute of Medicine (IOM is also associated with lower rates of breastfeeding initiation and duration in women. The aim of this pilot randomised controlled trial is to examine the feasibility of recruiting and maintaining a cohort of pregnant women with the view of reducing postpartum weight retention and improving breastfeeding outcomes. Women (BMI of 25–35 kg/m2 (n = 36 were recruited from the John Hunter Hospital antenatal clinic in New South Wales, Australia. Participants were stratified by BMI and randomised to one of three groups with follow-up to six months postpartum. Women received a dietary intervention with or without breastfeeding support from a lactation consultant, or were assigned to a wait-list control group where the dietary intervention was issued at three months postpartum. Feasibility and acceptability was assessed by participation rates and questionnaire. Analysis of variance and covariance was conducted to determine any differences between groups. Sixty-nine per cent of the participants were still enrolled at six months postpartum. This pilot demonstrated some difficulties in recruiting women from antenatal clinics and retaining them in the trial. Although underpowered; the results on weight; biomarkers and breastfeeding outcomes indicated improved metabolic health.

    Full Text Available The rapid development of mobile Internet has offered the opportunity for WiFi indoor positioning to come under the spotlight due to its low cost. However, nowadays the accuracy of WiFi indoor positioning cannot meet the demands of practical applications. To solve this problem, this paper proposes an improved WiFi indoor positioning algorithm by weighted fusion. The proposed algorithm is based on traditional location fingerprinting algorithms and consists of two stages: the offline acquisition and the online positioning. The offline acquisition process selects optimal parameters to complete the signal acquisition, and it forms a database of fingerprints by error classification and handling. To further improve the accuracy of positioning, the online positioning process first uses a pre-match method to select the candidate fingerprints to shorten the positioning time. After that, it uses the improved Euclidean distance and the improved joint probability to calculate two intermediate results, and further calculates the final result from these two intermediate results by weighted fusion. The improved Euclidean distance introduces the standard deviation of WiFi signal strength to smooth the WiFi signal fluctuation and the improved joint probability introduces the logarithmic calculation to reduce the difference between probability values. Comparing the proposed algorithm, the Euclidean distance based WKNN algorithm and the joint probability algorithm, the experimental results indicate that the proposed algorithm has higher positioning accuracy.

    To identify factors that might influence physicians' referrals of obese adolescents to pediatric multidisciplinary weight management (PMWM) programs. Survey of a national sample of 375 pediatricians (PDs) and 375 family physicians (FPs) explored program availability, referral history, desired services, and when in the course of treatment physicians would refer. Differences were examined via chi(2) tests. Response rate was 67%. More PDs than FPs reported having a PMWM program available (46% vs 10%, P < .01). More PDs (PD 83% vs FP 53%, P < .01) and female physicians (88% vs 65%, P < .01) reported having made a referral. Most physicians wanted coordinated diet, activity, and behavioral therapy (79%). Almost all physicians indicated they would refer when unsure of what else to do, or if requested by the patient/parent. PMWM program referrals appear limited by availability. These data also suggest physicians may be reticent to refer. Further work should examine whether this affects patient outcomes.

    This paper describes an inter-professional service learning collaboration and reflects benefits and considerations when incorporating a family-oriented approach in the community-based pediatric weight management program. Because obesity has tremendous consequences on a nation's health and economy, a pediatrician in a community health network has utilized an inter-professional team to implement a pediatric weight management program targeting children between the ages of 8 and 15 years. The team incorporates a culturally sensitive curriculum using a family-oriented approach for obesity prevention and intervention. Physicians, registered dietitians, occupational therapists, nurse practitioners, and mental health professionals assist participants in adopting a healthier lifestyle by addressing physical and psychosocial issues related to obesity, developing a nutrition plan, making healthier food choices, and finding fun ways to be more physically active. Graduate occupational therapy students work closely with the team members to assist delivery of interactive activities and behavior intervention.

    Compressive light field display with multilayer and multiframe decompositions is able to provide three-dimensional (3D) scenes with high spatial-angular resolution and without periodically repeating view-zones. However, there are still some limitations on the display performance, such as poor image quality and limited field of view (FOV). Compressive light field display with the viewing-position-dependent weight distribution is presented. When relevant views are given high weights in the optimization, the displaying performance at the viewing-position can be noticeably improved. Simulation and experimental results demonstrate the effectiveness of the proposed method. Peak signal-noise-ration (PSNR) is improved by 7dB for the compressive light field display with narrow FOV. The angle for wide FOV can be expended to 70° × 60°, and multi-viewers are supported.

    Treatment of obesity has become one of the most challenging issues. The aims of the authors were to present the results of standard behavior therapy weight loss program combined with self-help and the results of one-year follow-up. The 24-week program involved 41 participants of which 33 subjects participated in the follow-up. Anthropometric data were obtained and the participants were asked to fill questionnaires (the 21 items Three Factor Eating Questionnair Revised 21 items; Physical Exercise: Steps of change [Short Form]. 87.8% of participants achieved a minimum weight loss of 5% which is the rate expected in professional therapies for obesity. Significant changes in maladaptive eating pattern and an increase in the rate of regular exercise were observed. Significant association was found between the increase of cognitive restraint and the rate of weight loss during treatment. At one-year follow-up the majority of participants (75.8%) did keep their minimum weight loss of 5% and they showed significant change in eating pattern. The results suggest that standard behavior therapy extended with self-help elements may be a cost-effective treatment of obesity.

    Full Text Available Abstract Background Recent evidence suggests that a low carbohydrate (LC diet may be equally or more effective for short-term weight loss than a traditional low fat (LF diet; however, less is known about how they compare for weight maintenance. The purpose of this study was to compare body weight (BW for participants in a clinical weight management program, consuming a LC or LF weight maintenance diet for 6 months following weight loss. Methods Fifty-five (29 low carbohydrate diet; 26 low fat diet overweight/obese middle-aged adults completed a 9 month weight management program that included instruction for behavior, physical activity (PA, and nutrition. For 3 months all participants consumed an identical liquid diet (2177 kJ/day followed by 1 month of re-feeding with solid foods either low in carbohydrate or low in fat. For the remaining 5 months, participants were prescribed a meal plan low in dietary carbohydrate (~20% or fat (~30%. BW and carbohydrate or fat grams were collected at each group meeting. Energy and macronutrient intake were assessed at baseline, 3, 6, and 9 months. Results The LC group increased BW from 89.2 ± 14.4 kg at 3 months to 89.3 ± 16.1 kg at 9 months (P = 0.84. The LF group decreased BW from 86.3 ± 12.0 kg at 3 months to 86.0 ± 14.0 kg at 9 months (P = 0.96. BW was not different between groups during weight maintenance (P = 0.87. Fifty-five percent (16/29 and 50% (13/26 of participants for the LC and LF groups, respectively, continued to decrease their body weight during weight maintenance. Conclusion Following a 3 month liquid diet, the LC and LF diet groups were equally effective for BW maintenance over 6 months; however, there was significant variation in weight change within each group.

  20. Relationships Between Seed Weight, Germination Potential and Biochemical Reserves of Maritime Pine in Morocco: Elements for Tree Seedlings Improvement

    2011-01-01

    Selection of quality seeds in breeding programs can significantly improve seedling productivity. Germination and biochemical analyses on seeds from ten natural populations of maritime pine (Pinus pinaster Ait.) in Morocco reveals significant differences among populations in seed weight, germination characters and protein content in both dry seeds and megagametophytes. During germination, the mobilization of protein content in megagametophyte is significantly different among populations than sugar content. A strong positive correlation between the germination capacity and the protein content in both dry seeds and megagametophytes indicates that the best populations in term of germination capacity may also be the richest in protein content. The present study finds that seed weight is not a good indicator for quality seed selection, nor is it recommended to increase the degree of germinability. Our results suggest that the pine population in southern Morocco might have adapted to drought conditions as it is characterized by heavy seed weight and lower speed of protein content mobilization in megagametophyte compared to northern populations growing in temperate climate.

    The MATADOR (Minimising Adaptive Thermogenesis And Deactivating Obesity Rebound) study examined whether intermittent energy restriction (ER) improved weight loss efficiency compared with continuous ER and, if so, whether intermittent ER attenuated compensatory responses associated with ER. Fifty-one men with obesity were randomised to 16 weeks of either: (1) continuous (CON), or (2) intermittent (INT) ER completed as 8 × 2-week blocks of ER alternating with 7 × 2-week blocks of energy balance (30 weeks total). Forty-seven participants completed a 4-week baseline phase and commenced the intervention (CON: N=23, 39.4±6.8 years, 111.1±9.1 kg, 34.3±3.0 kg   m -2 ; INT: N=24, 39.8±9.5 years, 110.2±13.8 kg, 34.1±4.0 kg   m -2 ). During ER, energy intake was equivalent to 67% of weight maintenance requirements in both groups. Body weight, fat mass (FM), fat-free mass (FFM) and resting energy expenditure (REE) were measured throughout the study. For the N=19 CON and N=17 INT who completed the intervention per protocol, weight loss was greater for INT (14.1±5.6 vs 9.1±2.9 kg; Penergy balance blocks was minimal (0.0±0.3 kg). While reduction in absolute REE did not differ between groups (INT: -502±481 vs CON: -624±557 kJ d -1 ; P=0.5), after adjusting for changes in body composition, it was significantly lower in INT (INT: -360±502 vs CON: -749±498 kJ d -1 ; Penergy balance 'rest periods' may reduce compensatory metabolic responses and, in turn, improve weight loss efficiency.

    Osteoarthritis causes severe pain and disability in joints, one of the most prevalent involved joints is the knee joint. There are several therapeutics ways to control pain and disability, but almost none of them are definite treatment. In this article, we tried to reveal the effect of weight loss on improving symptoms of knee osteoarthritis as an effective and permanent therapeutic approach. We chose 62 patients with grade 1-2 (mild to moderate) knee osteoarthritis and divided them equally into case and control groups. Patients should not had used NSAIDs at least for 6 months before study initiation. Symptoms severity was measured by WOMAC and VAS questionnaires before and after 3 months follow up. Weight and BMI were recorded too. Case group was suggested to have weight loss diet of less fat and carbohydrates and control group did not have any limitation. Comparison of variables' average of case and control groups was not logistically meaningful at the initiation and after the end of the study. But there was a meaningful correlation between variables' changes and lifestyle change in both groups, especially in WOMAC and VAS scores. All variables in case group had statistically meaningful differences between their amounts at the beginning and after the end of the study, on the contrary of the control group. In the comparison of our study with similar studies in the world. We deduced that weight loss can improve symptoms of knee osteoarthritis even in short time weight loss diet (3 months).

    Obesity is independently associated with left ventricular (LV) diastolic dysfunction and altered cardiac morphology. Morbidity and mortality in patients with diastolic dysfunction are similar to values observed in patients with systolic heart failure. We hypothesized that dysfunctional cardiac responses in people with obesity are reversible after weight loss. Thus, we studied the effect of dietary weight reduction on LV diastolic function as well as on cardiac structure using transthoracic echocardiography and tissue Doppler imaging (TDI). Thirty-two subjects with obesity underwent a 12-week low-calorie fasting phase of a formula diet. Echocardiographic tissue Doppler indices of diastolic function and measurements of cardiac size were obtained prior to and after the fasting phase. A 12-week diet significantly reduced body mass index from 40.3 ± 6.6 kg/m(2) to 33.2 ± 6.1 kg/m(2) (p < 0.01). Weight loss was associated with a significant reduction in blood pressure and heart rate. Echocardiography revealed diastolic dysfunction in subjects with obesity, which was improved by dieting. After weight loss, trans-mitral Doppler echocardiography showed a significant reduction in A-wave velocity, from 65.8 ± 19.2 cm/s to 57.0 ± 16.8 cm/s, and an increase in E/A ratio from 1.2 ± 0.4 to 1.4 ± 0.5 (p < 0.01). TDI displayed a significantly lower a'-wave velocity (10.3 ± 2.3 cm/s and 8.9 ± 1.7 cm/s; p < 0.01). Left atrial and LV dimensions were normal and remained unchanged after weight loss. Obesity is associated with diastolic dysfunction. A 12-week low-calorie diet with successful weight loss can reduce blood pressure and heart rate and partially normalize diastolic dysfunction.

    Full Text Available BackgroundIt has recently been suggested that skeletal muscle has an important role in insulin resistance in obesity, in addition to exercise tolerance and the fat index. The aim of this study was to identify body composition factors that contribute to improvement of insulin resistance in female patients with obesity who reduce body weight.MethodsWe studied 92 female obese patients (age 40.9±10.4 years, body mass index 33.2±4.6 kg/m2 who reduced body weight by ≥5% after an intervention program including diet, exercise therapy, and cognitive behavioral therapy. Before and after the intervention, body composition was evaluated by dual-energy X-ray absorptiometry to examine changes in skeletal muscle mass. Homeostasis model assessment of insulin resistance (HOMA-IR was measured as an index of insulin resistance. Cardiopulmonary exercise was also performed by all patients.ResultsThere were significant improvements in body weight (–10.3%±4.5%, exercise tolerance (anaerobic threshold oxygen uptake 9.1%±18.4%, peak oxygen uptake 11.0%±14.2%, and HOMA-IR (–20.2%±38.3%. Regarding body composition, there were significant decreases in total body fat (–19.3%±9.6%, total fat-free mass (–2.7%±4.3%, and % body fat (–10.1%±7.5%, whereas % skeletal muscle significantly increased (8.9%±7.2%. In stepwise multiple linear regression analysis with change in HOMA-IR as the dependent variable, the change in % skeletal muscle was identified as an independent predictor (β=–0.280, R2=0.068, P<0.01.ConclusionImprovement of insulin resistance in female obese patients requires maintenance of skeletal muscle mass.

    Full Text Available Background: In order to develop appropriate obesity control and treat¬ment strategies, the key point is to understand the barriers perceived by overweight or obese people in trying to follow weight-loss programs. This study examined perceived barriers to weight-loss programs among over¬weight or obese women.Methods: In this descriptive-analytical study, 204 overweight or obese women aged 31.97± 10.62 yr, were selected randomly from the nutritional counseling centers in 2008 in Tabriz, Iran. The mean BMI was 33.83 ±5.75 kg/ m2. A structured questionnaire including questions on barriers to weight-loss diet and physical activity was filled out for each participant by face-to-face interview. Height and weight measured objectively and demo¬graphic details were obtained. Data analysis carried out using mul¬tiple re¬gression and factor analysis.Results: The most important perceived barriers to weight-loss diets were 'situational barriers', stress, depression, and food craving. High educational level was independent determinant of situational barriers (β=0.329, P=0.048. Employee women had a higher mean score on stress and de¬pres¬sion than students and housewives. Lack of time and exercising lonely were the most important items of "External barriers" and Lack of motiva¬tion was the most important item of "internal barriers" to physical activity. Employ¬ment and being student were highly associated with external bar¬riers (β=1.018, P<0.001 and β=0.541, P= 0.002. Moreover, older women who had low educational level, perceived more internal barriers. Conclusion: Weight reducing strategies should take into account the spe¬cific perceived barriers to weight-loss diets faced by overweight or obese women, particularly situational barriers, stress and depression and food craving; and lack of time and lack of motivation as barriers to physical ac¬tivity.

    Both the gene encoding the alpha subunit of G stimulatory proteins (GNAS1) and the beta3 subunit gene (GNB3) of G proteins are associated with obesity and/or hypertension. Moreover, the TT/TC825 polymorphism of GNB3 predicts greater weight loss than the CC825 polymorphism in obese patients (mean body mass index, 35 kg/m2) undergoing a structured nonpharmacologic weight loss program. Gastric banding enforces a low-calorie diet by diminishing the need for volitional adherence. It is unknown whether these polymorphisms predict the variable weight loss in patients after bariatric surgery. Three hundred and four severely obese patients (mean +/- SEM age, 42 +/- 1 years; 245 women and 59 men; mean +/- SEM body mass index, 43.9 +/- 0.3 kg/m2) followed prospectively for at least 3 years after surgery were genotyped for the GNB3 C825T, G814A, and GNAS1 T393 polymorphisms. All analyses were performed blinded to the phenotypic characteristics of the study group. Frequencies of polymorphisms were comparable to those previously published. No polymorphism studied predicted 3-year weight loss or was associated with high blood pressure in severely obese patients after gastric banding. Multivariate analysis of potentially confounding factors such as reoperation rate or use of sibutramine or orlistat revealed similar results (P > 0.1). Regardless of the mechanism(s) involved for these discordant findings, GNB3 C825T, G814A, and GNAS1 T393C polymorphisms do not seem to be reliable predictors of long-term weight loss.

    Weight loss treatment effectiveness and cost-effectiveness may be improved by the identification of patients who are more prone to participate and gain benefit from specific interventions. Aim of the present study is to identify easily available additional predictors of weight loss among data usually present in the medical records of obese/overweight patients attending an outpatient clinic for a non-pharmacological lifestyle change program. 268 patients, 74 men and 195 women (age 43.2 ± 11.9 years, BMI 38.9 ± 6.8 kg/m(2)) were enrolled. Among these patients, only 35.6 % men and 22.7 % women completed the 6-month protocol. Among participants, 50.7 % lost at least 5 % initial body weight after 6 months (SUCCESSES), while 49.3 % failed (FAILURES). Baseline nutritional parameters (total Kcal, lipid, carbohydrate, protein and alcohol intake) were not significantly different in successes when compared to failures, while a significant difference between groups was observed for baseline diastolic blood pressure (DBP); free fat mass (FFM); muscle mass (MM); total body water (TBW); HDL cholesterol; ALT; AST; γGT. After dividing into quartiles the not-normally distributed variables, successes had AST values above median (3rd and 4th quartiles; χ (2) = 0.003). At multivariate analysis (linear regression), the OR was 3.34 (1.42-7.85; p = 0.006). In our patients, baseline liver enzyme levels (AST in particular), but not baseline quantitative and qualitative dietary intake, were significantly different in successes versus failures and could therefore represent a predictor of success. In conclusion, AST could represent a usually available biomarker that could be used as a predictor of outcome (weight loss) in obese patients starting a lifestyle change program.

    To determine whether baseline levels of self-reported sleep and sleep problems among obese adolescents referred to an outpatient multidisciplinary family-based weight management program predict reduction in BMI 3 months later. A retrospective medical chart review was conducted for 83 obese adolescents. The following baseline variables were extracted: self-reported sleep duration (weekdays and weekends), and presence of snoring, daytime fatigue, suspected sleep apnea, and physician-diagnosed sleep apnea. Anthropometric data at baseline and 3 months were also collected. On average, adolescents reported significantly less sleeping on weeknights (7.7 ± 1.3 h) compared to weekend nights (10.0 ± 1.8 h), t(82) = 10.5, p = 0.0001. Reduction in BMI after 3 months of treatment was predicted by more weekly sleep at baseline (R² = 0.113, F(1, 80) = 10.2, p = 0.002). Adolescents who reduced their BMI by ≥1 kg/m² reported greater weekly sleep at baseline compared to adolescents who experienced <1 kg/m² reduction (60.7 ± 7.5 h vs. 56.4 ± 8.6 h; F(1, 80) = 5.7, p = 0.02). Findings from this study, though correlational, raise the possibility that increased duration of sleep may be associated with weight loss among obese adolescents enrolled in a weight management program. Evidence-based behavioral techniques to improve sleep hygiene and increase sleep duration should be explored in pediatric weight management settings. Copyright © 2013 S. Karger GmbH, Freiburg

    Full Text Available Okra (Abelmoschus esculentus is reported to have various biological functions such as antioxidant, anticancer and anti-inflammation. However, only few studies have been reported immunomodulatory activities of okra to prevent disease caused by bacteria infection. In this study, the immunomodulatory activities of polysaccharides from okra pods were investigated further through the spleen weight and B-lymphocytes proliferation in mice infected by Staphylococcus aureus. Okra polysaccharides were obtained by water extraction and ethanol precipitation. Okra polysaccharides with doses of 25, 50, 75, and 100 mg/kg BW were orally administrated to mice with or without Staphylococcus aureus infection. Spleen weight was evaluated in both treatment group and control group. B-lymphocytes proliferation was evaluated by MTT assay using LPS induction. Results showed that okra polysaccharide at the doses of 50, 75, and 100 mg/kg increased spleen weight (p < 0.05 significantly. While at the dose of 75 and 100 mg/kg, it increased the B-lymphocytes proliferation (p < 0.05 significantly. There is positive correlation between the spleen weight and B-lymphocytes proliferation by 73.3%. These result reveal that okra polysaccharide could improve the immune response and be utilized as a novel candidate of neutraceutical.

    Objectives: to evaluate the preliminary results obtained using diffusion-weighted magnetic resonance imaging and the apparent diffusion coefficient for planning computed tomography-guided biopsies of selected mediastinal lesions. Methods: eight patients with mediastinal lesions suspicious for malignancy were referred for computed tomography-guided biopsy. Diffusion-weighted magnetic resonance imaging and apparent diffusion coefficient measurement were performed to assist in biopsy planning with diffusion/computed tomography fused images. We selected mediastinal lesions that could provide discordant diagnoses depending on the biopsy site, including large heterogeneous masses, lesions associated with lung atelectasis or consolidation, lesions involving large mediastinal vessels and lesions for which the results of biopsy using other methods and histopathological examination were divergent from the clinical and radiological suspicion. Results: in all cases, the biopsy needle was successfully directed to areas of higher signal intensity on diffusion weighted sequences and the lowest apparent diffusion coefficient within the lesion (mean, 0.8 [range, 0.6–1.1]610{sup -3} mm{sup 2}/s), suggesting high cellularity. All biopsies provided adequate material for specific histopathological diagnoses of four lymphomas, two sarcomas and two thymoma s. Conclusion: functional imaging tools, such as diffusion-weighted imaging and the apparent diffusion coefficient, are promising for implementation in noninvasive and imaging-guided procedures. However, additional studies are needed to confirm that mediastinal biopsy can be improved with these techniques. (author)

    Hormonal fluctuations during the menstrual cycle influence energy intake and expenditure as well as eating preferences and behavior. We examined the effect in healthy, overweight, premenopausal women of a diet and exercise weight-loss program that was designed to target and moderate the effects of the menstrual cycle compared with the effect of simple energy restriction. A total of 60 healthy, overweight, premenopausal women were included in a 6-mo weight-loss program in which each subject consumed a diet of 1600 kcal/d. Subjects were randomly assigned to either a combined diet and exercise program that was tailored to metabolic changes of the menstrual cycle (Menstralean) or to undergo simple energy restriction (control). Thirty-one women (19 Menstralean and 12 control women) completed the study [mean ± SD body mass index (in kg/m(2)): 32.0 ± 5.2]. Both groups lost weight during the study. In an intention-to-treat analysis, the Menstralean group did not achieve a clinically significant weight loss compared with that of the control group (P = 0.61). In per-protocol analyses, a more-pronounced weight loss of 4.3 ± 1.4 kg (P = 0.002) was shown in adherent Menstralean subjects than in the control group. A differentiated diet and exercise program that is tailored to counteract food cravings and metabolic changes throughout the menstrual cycle may increase weight loss above that achieved with a traditional diet and exercise program in women who can comply with the program.

    Internet-based physical activity (PA) and weight management programs have the potential to improve employees' health in large occupational health settings. To be successful, the program must engage a wide range of employees, especially those at risk of weight gain or ill health. The aim of the study was to assess the use and nonuse (user attrition) of a Web-based and monitoring device-based PA and weight management program in a range of employees and to determine if engagement with the program was related to the employees' baseline characteristics or measured outcomes. Longitudinal observational study of a cohort of employees having access to the MiLife Web-based automated behavior change system. Employees were recruited from manufacturing and office sites in the North West and the South of England. Baseline health data were collected, and participants were given devices to monitor their weight and PA via data upload to the website. Website use, PA, and weight data were collected throughout the 12-week program. Overall, 12% of employees at the four sites (265/2302) agreed to participate in the program, with 130 men (49%) and 135 women (51%), and of these, 233 went on to start the program. During the program, the dropout rate was 5% (11/233). Of the remaining 222 Web program users, 173 (78%) were using the program at the end of the 12 weeks, with 69% (153/222) continuing after this period. Engagement with the program varied by site but was not significantly different between the office and factory sites. During the first 2 weeks, participants used the website, on average, 6 times per week, suggesting an initial learning period after which the frequency of website log-in was typically 2 visits per week and 7 minutes per visit. Employees who uploaded weight data had a significant reduction in weight (-2.6 kg, SD 3.2, Pweight was largest for employees using the program's weight loss mode (-3.4 kg, SD 3.5). Mean PA level recorded throughout the program was 173 minutes

    Full Text Available Poor maternal nutritional status and substandard antenatal care, which result in increased women's risk, low birth weight and stillbirth, afflict many countries with weak or emerging economies even today. Studies that address the effect of extending nutrition awareness among pregnant women to the net outcome of pregnancy remain scarce. We aimed to compare and contrast the effect of a pragmatic nutrition awareness program for expectant mothers (NAPEM on birth weight of the newborn with a control group who received no such nutrition awareness activity. The effect of variables of mode of newborn delivery, associated complications at birth, and APGAR score of the newborn were also assessed. A pragmatic intervention trial of an antenatal care (ANC program that consisted in nutrition awareness was conducted involving 53 pregnant women. Awareness was given through one-to-one interview and through informational literature provided to the participants in the local language. A hospital registry for deliveries undertaken during the study period was screened for identification of variables. A control group of matched pregnant women (n = 53 was obtained from the same hospital registry from preceding years, when the nutrition awareness program was not executed. A statistically significant improvement in birth weight of the newborn was observed in the intervention group, where expectant mothers were made aware about desired nutrition during pregnancy. A reduced incidence of complications associated with pregnancy was also observed in the intervention group. Providing awareness about nutritional requirements during pregnancy and suggesting the pragmatic ways to meet them was shown to be one possible effective measure to deal with pregnancy-related undernutrition. We show the efficacy of the intervention for underprivileged regions of India marked by inadequate health care delivery and lower socio-economical standards. We discuss our findings in the context of

    Entropy measures are recently extensively used to study the complexity property in nonlinear systems. Weighted permutation entropy (WPE) can overcome the ignorance of the amplitude information of time series compared with PE and shows a distinctive ability to extract complexity information from data having abrupt changes in magnitude. Improved (or sometimes called composite) multi-scale (MS) method possesses the advantage of reducing errors and improving the accuracy when applied to evaluate multiscale entropy values of not enough long time series. In this paper, we combine the merits of WPE and improved MS to propose the improved multiscale weighted permutation entropy (IMWPE) method for complexity investigation of a time series. Then it is validated effective through artificial data: white noise and 1 / f noise, and real market data of Brent and Daqing crude oil. Meanwhile, the complexity properties of crude oil markets are explored respectively of return series, volatility series with multiple exponents and EEMD-produced intrinsic mode functions (IMFs) which represent different frequency components of return series. Moreover, the instantaneous amplitude and frequency of Brent and Daqing crude oil are analyzed by the Hilbert transform utilized to each IMF.

    OBJECTIVE: To determine fluctuations in total body weight of the elite collegiate wrestler during the competitive season. DESIGN AND SETTING: The study period lasted 2 competitive seasons, beginning 1 month before the 1999-2000 and 2000- 2001 competitive seasons and ending 1 month after the National Championships. SUBJECTS: Seventy-eight male subjects (age = 21.3 +/- 1.5 years, height = 154.1 +/- 0.5 cm) from 4 major universities whose teams finished in the top 5 at both the 2000 and 2001 National Collegiate Athletic Association Division I National Wrestling Championships. MEASUREMENTS: Each subject was asked to report to the testing area 24 hours before, 1 hour before, and 24 hours after a competitive wrestling match, and weight was recorded to the nearest 0.1 lb (0.45 kg). Comparisons among the prematch weights, official weigh-ins, and postmatch weights were made using a randomized, 1-group, repeated-measures factorial analysis of covariance with an alpha level of.05. RESULTS: A significant difference (F(2,154) = 229.99, P body-weight changes 24 hours and 1 hour before the match (t(77) = 56.21, P <.0001). CONCLUSIONS: Elite collegiate wrestlers, like novice wrestlers, significantly reduce weight immediately before and gain weight after the competition.

    The Accreditation Council for Graduate Medical Education (ACGME) requires programs to engage annually in program evaluation and improvement. We assessed the value of creating educational competency committees (ECCs) that use successful elements of 2 established processes-institutional special reviews and institutional oversight of annual program evaluations. The ECCs used a template to review programs' annual program evaluations. Results were aggregated into an institutional dashboard. We calculated the costs, sensitivity, specificity, and predictive value by comparing programs required to have a special review with those that had ACGME citations, requests for a progress report, or a data-prompted site visit. We assessed the value for professional development through a participant survey. Thirty-two ECCs involving more than 100 individuals reviewed 237 annual program evaluations over a 3-year period. The ECCs required less time than internal reviews. The ECCs rated 2 to 8 programs (2.4%-9.8%) as "noncompliant." One to 13 programs (1.2%-14.6%) had opportunities for improvement identified. Institutional improvements were recognized using the dashboard. Zero to 13 programs (0%-16%) were required to have special reviews. The sensitivity of the decision to have a special review was 83% to 100%; specificity was 89% to 93%; and negative predictive value was 99% to 100%. The total cost was $280 per program. Of the ECC members, 86% to 95% reported their participation enhanced their professional development, and 60% to 95% believed the ECC benefited their program. Educational competency committees facilitated the identification of institution-wide needs, highlighted innovation and best practices, and enhanced professional development. The cost, sensitivity, specificity, and predictive value indicated good value.

    Full Text Available Abstract Background Nearly 60% of black women are obese. Despite their increased risk of obesity and associated chronic diseases, black women have been underrepresented in clinical trials of weight loss interventions, particularly those conducted in the primary care setting. Further, existing obesity treatments are less effective for this population. The promotion of weight maintenance can be achieved at lower treatment intensity than can weight loss and holds promise in reducing obesity-associated chronic disease risk. Weight gain prevention may also be more consistent with the obesity-related sociocultural perspectives of black women than are traditional weight loss approaches. Methods/Design We conducted an 18-month randomized controlled trial (the Shape Program of a weight gain prevention intervention for overweight black female patients in the primary care setting. Participants include 194 premenopausal black women aged 25 to 44 years with a BMI of 25–34.9 kg/m2. Participants were randomized either to usual care or to a 12-month intervention that consisted of: tailored obesogenic behavior change goals, self-monitoring via interactive voice response phone calls, tailored skills training materials, 12 counseling calls with a registered dietitian and a 12-month YMCA membership. Participants are followed over 18 months, with study visits at baseline, 6-, 12- and 18-months. Anthropometric data, blood pressure, fasting lipids, fasting glucose, and self-administered surveys are collected at each visit. Accelerometer data is collected at baseline and 12-months. At baseline, participants were an average of 35.4 years old with a mean body mass index of 30.2 kg/m2. Participants were mostly employed and low-income. Almost half of the sample reported a diagnosis of hypertension or prehypertension and 12% reported a diagnosis of diabetes or prediabetes. Almost one-third of participants smoked and over 20% scored above the clinical threshold

    Munsters, M J M; Saris, W H M

    2014-01-01

    This review discusses dietary strategies that may improve the metabolic profile and body weight regulation in obesity. Recent evidence demonstrated that long-term health effects seem to be more beneficial for low-glycemic index (GI) diets compared to high-protein diets. Still, these results need to be confirmed by other prospective cohort studies and long-term clinical trials, and the discrepancy between these study designs needs to be explored in more detail. Furthermore, the current literature is mixed with regard to the efficacy of increased meal frequency (or snacking) regimens in causing metabolic alterations, particularly in relation to body weight control. In conclusion, a growing body of evidence suggests that dietary strategies with the aim to reduce postprandial insulin response and increase fat oxidation, and that tend to restore metabolic flexibility, have a place in the prevention and treatment of obesity and associated metabolic disorders.

    To determine the effects of "strides" with a weighted-vest during a warm-up on endurance performance and its potential neuromuscular and metabolic mediators. A bout of resistance exercise can enhance subsequent high-intensity performance, but little is known about such priming exercise for endurance performance. A crossover with 5-7 days between an experimental and control trial was performed by 11 well-trained distance runners. Each trial was preceded by a warm-up consisting of a 10-min self-paced jog, a 5-min submaximal run to determine running economy, and six 10-s strides with or without a weighted-vest (20% of body mass). After a 10-min recovery period, runners performed a series of jumps to determine leg stiffness and other neuromuscular characteristics, another 5-min submaximal run, and an incremental treadmill test to determine peak running speed. Clinical and non-clinical forms of magnitude-based inference were used to assess outcomes. Correlations and linear regression were used to assess relationships between performance and underlying measures. The weighted-vest condition resulted in a very-large enhancement of peak running speed (2.9%; 90% confidence limits ±0.8%), a moderate increase in leg stiffness (20.4%; ±4.2%) and a large improvement in running economy (6.0%; ±1.6%); there were also small-moderate clear reductions in cardiorespiratory measures. Relationships between change scores showed that changes in leg stiffness could explain all the improvements in performance and economy. Strides with a weighted-vest have a priming effect on leg stiffness and running economy. It is postulated the associated major effect on peak treadmill running speed will translate into enhancement of competitive endurance performance. Copyright © 2013 Sports Medicine Australia.

Morbidity and mortality in patients with diastolic dysfunction are similar to values observed in patients with systolic heart failure. We hypothesized that dysfunctional cardiac responses in people with obesity are reversible after weight loss. Thus, we studied the effect of dietary weight reduction on LV diastolic function as well as on cardiac structure using transthoracic echocardiography and tissue Doppler ­imaging (TDI. Subjects/methods: Thirty-two subjects with obesity underwent a 12-week low-calorie fasting phase of a formula diet. Echocardiographic tissue Doppler indices of diastolic function and measurements of cardiac size were obtained prior to and after the fasting phase. Results: A 12-week diet significantly reduced body mass index from 40.3 ± 6.6 kg/m2 to 33.2 ± 6.1 kg/m2 (p < 0.01. Weight loss was associated with a significant reduction in blood pressure and heart rate. Echocardiography revealed diastolic dysfunction in subjects with obesity, which was improved by dieting. After weight loss, trans-mitral Doppler echocardiography showed a significant reduction in A-wave velocity, from 65.8 ± 19.2 cm/s to 57.0 ± 16.8 cm/s, and an increase in E/A ratio from 1.2 ± 0.4 to 1.4 ± 0.5 (p < 0.01. TDI displayed a significantly lower a′-wave velocity (10.3 ± 2.3 cm/s and 8.9 ± 1.7 cm/s; p < 0.01. Left atrial and LV dimensions were normal and remained unchanged after weight loss. Conclusion: Obesity is associated with diastolic dysfunction. A 12-week low-calorie diet with successful weight loss can reduce blood pressure

    According to the current evidence, behavior modifications are an effective part of a non-surgical multiprofessional obesity treatment program (MOTP). The purpose of the present study was to report changes in weight as well in psychological variables during a one year MOTP. We aimed to identify the associations of emotional state and patients' emotion regulation skills with weight change. Prospective interventional study. Data of participants attending the one year obesity treatment in either a group or individual structured MOTP were analyzed. Weight, BMI (Body Mass Index) and measures on psychosomatic variables, emotion regulation skills, affective state, shame and guilt were collected at baseline, after three months and after one year. Mixed-effects models were used for the statistical analysis of BMI. We included 238 patients at baseline (t1), 234 after three months (t2) and 179 after one year (t3). A drop in BMI measurements of at least 5% was observed in 20.6% of participants at t2 and 41.4% of participants at t3. After three months, participants showed significant improvements in the following psychosomatic variables: somatisation (p treatment of psychological aspects like depression, emotion regulation skills, body awareness, and acceptance should be a vital part of an interdisciplinary MOPT.

    Postpartum weight retention increases lifetime risk of obesity and related morbidity. Few effective interventions exist for multicultural, low-income women. To test whether an internet-based weight loss program in addition to the Special Supplemental Nutrition Program for Women, Infants, and Children (WIC program) for low-income postpartum women could produce greater weight loss than the WIC program alone over 12 months. A 12-month, cluster randomized, assessor-blind, clinical trial enrolling 371 adult postpartum women at 12 clinics in WIC programs from the California central coast between July 2011 and May 2015 with data collection completed in May 2016. Clinics were randomized to the WIC program (standard care group) or the WIC program plus a 12-month primarily internet-based weight loss program (intervention group), including a website with weekly lessons, web diary, instructional videos, computerized feedback, text messages, and monthly face-to-face groups at the WIC clinics. The primary outcome was weight change over 12 months, based on measurements at baseline, 6 months, and 12 months. Secondary outcomes included proportion returning to preconception weight and changes in physical activity and diet. Participants included 371 women (mean age, 28.1 years; Hispanic, 81.6%; mean weight above prepregnancy weight, 7.8 kg; mean months post partum, 5.2 months) randomized to the intervention group (n = 174) or standard care group (n = 197); 89.2% of participants completed the study. The intervention group produced greater mean 12-month weight loss compared with the standard care group (3.2 kg in the intervention group vs 0.9 kg in standard care group, P internet-based weight loss program in addition to the Special Supplemental Nutrition Program for Women, Infants, and Children (WIC program) compared with the WIC program alone resulted in a statistically significant greater weight loss over 12 months. Further research is needed to determine program and cost

    To determine the effect of orlistat, a new lipase inhibitor, on long-term weight loss, to determine the extent to which orlistat treatment minimizes weight regain in a second year of treatment, and to assess the effects of orlistat on obesity-related risk factors. This was a 2-year, multicenter, randomized, double-blind, placebo-controlled study. Obese patients (body mass index 28 to 43 kg/m2) were randomized to placebo or orlistat (60 or 120 mg) three times a day, combined with a hypocaloric diet during the first year and a weight maintenance diet in the second year of treatment to prevent weight regain. Changes in body weight, lipid profile, glycemic control, blood pressure, quality of life, safety, and tolerability were measured. Orlistat-treated patients lost significantly more weight (p<0.001) than placebo-treated patients after Year 1 (6.6%, 8.6%, and 9.7% for the placebo, and orlistat 60 mg and 120 mg groups, respectively). During the second year, orlistat therapy produced less weight regain than placebo (p = 0.005 for orlistat 60 mg; p<0.001 for orlistat 120 mg). Several obesity-related risk factors improved significantly more with orlistat treatment than with placebo. Orlistat was generally well tolerated and only 6% of orlistat-treated patients withdrew because of adverse events. Orlistat leads to predictable gastrointestinal effects related to its mode of action, which were generally mild, transient, and self-limiting and usually occurred early during treatment. Orlistat administered for 2 years promotes weight loss and minimizes weight regain. Additionally, orlistat therapy improves lipid profile, blood pressure, and quality of life.

    It has recently been suggested that skeletal muscle has an important role in insulin resistance in obesity, in addition to exercise tolerance and the fat index. The aim of this study was to identify body composition factors that contribute to improvement of insulin resistance in female patients with obesity who reduce body weight. We studied 92 female obese patients (age 40.9±10.4 years, body mass index 33.2±4.6 kg/m²) who reduced body weight by ≥5% after an intervention program including diet, exercise therapy, and cognitive behavioral therapy. Before and after the intervention, body composition was evaluated by dual-energy X-ray absorptiometry to examine changes in skeletal muscle mass. Homeostasis model assessment of insulin resistance (HOMA-IR) was measured as an index of insulin resistance. Cardiopulmonary exercise was also performed by all patients. There were significant improvements in body weight (-10.3%±4.5%), exercise tolerance (anaerobic threshold oxygen uptake 9.1%±18.4%, peak oxygen uptake 11.0%±14.2%), and HOMA-IR (-20.2%±38.3%). Regarding body composition, there were significant decreases in total body fat (-19.3%±9.6%), total fat-free mass (-2.7%±4.3%), and % body fat (-10.1%±7.5%), whereas % skeletal muscle significantly increased (8.9%±7.2%). In stepwise multiple linear regression analysis with change in HOMA-IR as the dependent variable, the change in % skeletal muscle was identified as an independent predictor (β=-0.280, R²=0.068, Pmuscle mass.

    A 6-month weight-management program with full meal replacement, low-calorie diet (full MR-LCD) (900 kcal/day for 6 to 12 weeks) follows a protocol for patients with diabetes for decreasing or discontinuing weight-gaining diabetes medications first (Group WG) and then titrating weight-neutral medications (Group WN). This is a retrospective cohort study (1992 to 2009) of weight, glycemic control and diabetes medications changes in 317 patients with obesity and type 2 diabetes who were taking medications. Group WG and Group WN were similar at baseline, except that glycated hemoglobin (A1C) levels were significantly lower in Group WN (7.5% vs. 6.6%; pmetformin. At 6 months, compared with baseline, A1C levels improved in Group WG and Group WN (6-month A1C levels 6.7% and 5.8%, respectively; pdiabetes medications and had significantly better percentages of weight loss compared with those taking medications (18.6% vs. 16%; p=0.002); both groups had improved glycemic control at 6 months (A1C 6.0% vs. A1C 6.6%; NS). In patients with obesity and type 2 diabetes taking medications, a full MR-LCD program appears to be safe and includes improvement in A1C levels. At 6 months, the percentage of weight loss can be significantly better in patients who no longer require diabetes medications, and A1C levels are best controlled in patients who are on WN medications.

    Compared with randomized trials, community-based interventions are delivered by a wider variety of professionals with varied training backgrounds. When evidence-based programs are scaled into larger formats and disseminated to a wider audience, little is understood about how clients experience these interventions. To understand the experience of clients after meetings with nutrition, exercise, and health behavior professionals, researchers surveyed participants after 6 months in a weight management program. A total of 958 participants were recruited in monthly cohorts beginning September 2011 to complete a program evaluation survey. Qualitative inductive analysis was completed on several open-text items querying respondents as to what they found helpful from meetings with a registered dietitian, personal trainer, and health behavior counselor. Results indicate participants benefitted from gaining knowledge, learning new behavioral skills, or from interpersonal interactions. Findings suggest that the various professional services are valued by clients and that professionals appear to stay within their scope of practice. Implications for those working in weight management are discussed. © 2015 Society for Public Health Education.

    Human milk has well-established health benefits for preterm infants. We conducted a multidisciplinary quality improvement effort aimed at providing at least 500 mL of human milk/kg in the first 14 days of life to very low birth weight (VLBW) (milk program, and twice-daily physician evaluation of infants' ability to tolerate feedings. The number of infants receiving at least 500 mL of human milk/kg in their first 14 days of life increased from 50% to 80% within 11 months of implementation, and this increase has been sustained for 4 years. Infants who met the feeding goal because they received donor milk increased each year. Since September 2007, infants have received, on average, 1,111 mL of human milk/kg. Approximately 4% of infants did not receive any human milk. Respiratory instability was the most frequent physiological reason given by clinicians for not initiating or advancing feedings in the first 14 days of life. Our quality improvement initiative resulted in a higher consumption of human milk in VLBW infants in the first 14 days of life. Other clinicians can use these described quality improvement methods and techniques to improve their VLBW babies' consumption of human milk.

    The majority of weight management research is based on data from randomized controlled studies conducted in clinical settings. As these findings are translated into community-based settings, additional research is needed to understand patterns of lifestyle change and dropout. The purpose of this study was to examine reasons for and consequences associated with dropout (or removal) from an insurance-funded weight management program. Using a mixed methods approach with objectively measured changes in body weight and attendance along with quantitative and qualitative survey data, patterns of intention and behavior change were explored. The results from a sample of 400 respondents support the idea that there are both positive and negative consequences of program participation. Overall, 1 in 5 respondents lost a clinically significant amount of weight during the program (>5% of baseline body weight) and 1 in 3 experienced a positive consequence, while only 6% expressed a negative outcome of participation. Additionally, nearly 90% of all of the consequences that emerged from the data were positive. Attitude change was a major theme, including positive health intentions, perceived success, learning skills, and new appreciation of exercise.

    This analysis investigated if changes in autonomous or controlled motivation for participation in a weight loss program differed between individuals offered a financial incentive for weight loss compared to individuals not offered an incentive. Additionally, the same relationships were tested among those who lost weight and either received or did not receive an incentive. This analysis used data from a year-long randomized worksite weight loss program that randomly assigned employees in each worksite to either a low-intensity weight loss program or the same program plus small financial incentives for weight loss ($5.00 per percentage of initial weight lost). There were no differences in changes between groups on motivation during the study, however, increases in autonomous motivation were consistently associated with greater weight losses. This suggests that the small incentives used in this program did not lead to increases in controlled motivation nor did they undermine autonomous motivation. Future studies are needed to evaluate the magnitude and timing of incentives to more fully understand the relationship between incentives and motivation.

    There is a critical need for weight management programs that are effective, cost efficient, accessible, and acceptable to adults from diverse ethnic and socioeconomic backgrounds. mHealth (delivered via mobile phone and Internet) weight management programs have potential to address this need. To maximize the success and cost-effectiveness of such an mHealth approach it is vital to develop program content based on effective behavior change techniques, proven weight management programs, and closely aligned with participants' needs. This study aims to develop an evidence-based mHealth weight management program (Horizon) using formative research and a structured content development process. The Horizon mHealth weight management program involved the modification of the group-based UK Weight Action Program (WAP) for delivery via short message service (SMS) and the Internet. We used an iterative development process with mixed methods entailing two phases: (1) expert input on evidence of effective programs and behavior change theory; and (2) target population input via focus group (n=20 participants), one-on-one phone interviews (n=5), and a quantitative online survey (n=120). Expert review determined that core components of a successful program should include: (1) self-monitoring of behavior; (2) prompting intention formation; (3) promoting specific goal setting; (4) providing feedback on performance; and (5) promoting review of behavioral goals. Subsequent target group input confirmed that participants liked the concept of an mHealth weight management program and expressed preferences for the program to be personalized, with immediate (prompt) and informative text messages, practical and localized physical activity and dietary information, culturally appropriate language and messages, offer social support (group activities or blogs) and weight tracking functions. Most target users expressed a preference for at least one text message per day. We present the prototype m

    The aim of this study was to investigate the effects of a 4-week weight reduction period with high protein and reduced carbohydrate intake on body composition, explosive power, speed, serum hormones, and acid-base balance in male track and field jumpers and sprinters. Eight participants were assigned to a high weight reduction group (HWR; energy restriction 750 kcal·d) and 7 to a low weight reduction group (LWR; energy restriction 300 kcal·d). Energy and carbohydrate intake decreased significantly (p ≤ 0.05) only in HWR by 740 ± 330 kcal·d and 130 ± 29 g·d, respectively. Furthermore, total body mass and fat mass decreased (p ≤ 0.05) only in HWR by 2.2 ± 1.0 kg and 1.7 ± 1.6 kg, respectively. Fat-free mass (FFM), serum testosterone, cortisol, and sex hormone-binding globulin did not change significantly. Ca ion and pH decreased (p ≤ 0.05) only in HWR (3.1 ± 2.8% and 0.8 ± 0.8%, respectively), whereas (Equation is included in full-text article.)declined (p ≤ 0.05) in both groups by 19.3 ± 6.2% in HWR and by 13.1 ± 8.5% in LWR. The countermovement jump and 20-m sprint time improved consistently (p ≤ 0.05) only in HWR, by 2.6 ± 2.5 cm and 0.04 ± 0.04 seconds, respectively. Finally, athletes with a fat percentage of 10% or more at the baseline were able to preserve FFM. In conclusion, altered acid-base balance but improved weight-bearing power performance was observed without negative consequences on serum hormones and FFM after a 4-week weight reduction of 0.5 kg·wk achieved by reduced carbohydrate but maintained high protein intake.

    We sought to determine whether a behavioral weight reduction intervention would improve nonurinary incontinence lower urinary tract storage symptoms at 6 months, including urinary frequency, nocturia and urgency, compared to a structured education program serving as the control group among overweight and obese women with urinary incontinence. PRIDE (Program to Reduce Incontinence by Diet and Exercise) was a randomized clinical trial performed in 338 overweight or obese women with urinary incontinence. Participants were randomized, including 226 to 6-month behavioral weight loss intervention and 112 to the control group. All participants received a self-help behavioral treatment booklet to improve bladder control. On this secondary data analysis we examined changes in nonurinary incontinence lower urinary tract storage symptoms from baseline to 6 months and the impact of treatment allocation (intervention vs control), weight loss and physical activity. Nonurinary incontinence lower urinary tract storage symptoms were common at baseline, varying from 48% to 62%. In the 2 groups combined women experienced significant improvement in nocturia, urgency and International Prostate Symptom Score at 6 months (all p incontinence. The prevalence decreased significantly after 6 months independent of treatment group assignment, amount of weight lost or physical activity. These improvements may have been due to self-help behavioral educational materials, trial participation or repeat assessment of symptoms.

    Children with disabilities are more likely to be overweight or obese and less likely to engage in physical activities versus their peers without disabilities. The effect of a structured afterschool program housed in a large county parks system on several obesity-related health outcomes among children with disabilities was examined. Children/adolescents with a developmental and/or intellectual disability ages 6-22 (N = 52, mean age 13.7 years) who participated in an afterschool (either 2010-2011 or 2011-2012 school year) health and wellness program called Fit-2-Play™ were assessed. Pre-post comparison of outcome variables (mean height, weight, waist/hip/midarm circumference, fitness tests, and a 9-item health and wellness knowledge assessment) via general linear mixed models analysis was conducted to evaluate the effectiveness of the program for normal and overweight/obese participants. Normal weight participants significantly improved pre-post mean number of push-ups (9.69-14.23, p = 0.01) and laps on the PACER test (8.54-11.38, p < 0.01) and the overweight/obese group significantly improved the number of sit ups (7.51-9.84, p < 0.01) and push ups (4.77-9.89, p < 0.001). Pre-post mean health and wellness knowledge composite scores significantly improved for all participants (p < 0.01). Parks-based afterschool programs can be effective community resources for instilling physical health in both normal weight and overweight/obese children with disabilities. More studies are needed to ascertain whether community-based afterschool health and wellness programs can be implemented and sustained across this population. Copyright © 2014 Elsevier Inc.

    Prospective comparative study. To evaluate whether weight percentile (WP) increases after VEPTR insertion, and whether WP correlates with nutrition labs and pulmonary function. Children with thoracic insufficiency syndrome (TIS) often have "failure to thrive" (WP ≤5). Previous authors have reported an increase in WP after VEPTR surgery. Weight gain was hypothesized to be secondary to improved pulmonary function. The presence of a correlation between WP, and nutrition labs and pulmonary function tests (PFT) after VEPTR insertion has not been studied. Demographic, nutrition, radiographic, and PFT data were collected on 35 VEPTR patients with a minimum follow-up of 2 years. The relationship between WP, and nutrition labs and pulmonary function was analyzed. Preoperative WP was ≤5 (PREOP≤5) in 13 patients (37%) and >5 (PREOP>5) in 22 patients (63%). Although all children gained weight, the PREOP≤5 group was more likely to have an increase in WP (P = 0.014). Sixty-eight percent of the PREOP>5 group had a decrease in WP and 32% of the PREOP>5 patients met the criteria for failure to thrive at final follow-up. Overall, there was no change in the number of children with a WP ≤5 (13 vs 15). Forty-two percent of the children who maintained or increased their WP had a gastrostomy tube, compared to 19% of those who decreased their WP. Seventy-three percent of the patients with failure to thrive at final follow-up did not have a gastrostomy tube. No significant correlations were found between WP and nutrition labs, radiographic measures, or PFTs. We did not find an overall change in WP after VEPTR insertion. We did not find any correlation between WP and nutrition labs or pulmonary function. Weight gain after VEPTR surgery may be secondary to nutritional optimization in high-risk patients. Children who do not have failure to thrive at presentation also require attention. 2.

    CONSTRUCT: The objective of this study was to evaluate the impact of varying the relative weights of cognitive versus noncognitive admission criteria on the proportion of underrepresented minorities admitted to medical school. It answers the question, "Can medical schools increase the admission rates of underrepresented minority (URM) students by balancing cognitive criteria with the experiences, attributes, and metrics of noncognitive data in the admission process?" U.S. demographics are shifting, and by 2042 ethnic minority groups will make up approximately 50% of the population. Increasing diversity of the U.S. population foreshadows the need to increase the number of physicians from underrepresented minorities to help address healthcare disparities that are on the rise. A cohort of three medical school applicant classes (2007-2009) was used to model the impact on URM admission rates as the relative weights of cognitive and noncognitive admission criteria were varied. This study used the minimum admission standards established for the actual incoming classes. The URM rate of admission to medical school was the outcome. Cognitive criteria included Medical College Admission Test scores and grade point averages. Noncognitive criteria included four categories: background and diversity, interest and suitability for a career in medicine, problem-solving and communication skills, and letters of recommendation. A cohort of 480 applicants from the three applicant classes were enrolled in the study. As the weighting scheme was varied from 50% cognitive/50% noncognitive weights to 35%/65%, the proportion of URM students accepted to medical school increased from 24% (42/177) to 30% (57/193; p noncognitive higher relative to cognitive criteria without compromising admission standards. Challenging conventional practice in the admissions process may improve health disparities and diversify the physician workforce.

    Full Text Available Abstract Background The current food pyramid guidelines have been criticized because of their complexity and the knowledge required for users to understand the recommendations. Simplification of a dietary message to focus on a single key aspect of dietary quality, e.g., fiber intake, may make the message much easier to comprehend and adhere, such that respondents can achieve greater weight loss, better dietary quality and overall metabolic health. Methods and design This is a randomized controlled clinical trial with two equal sized arms. In total, 240 obese adults who meet diagnostic criteria for the metabolic syndrome will be randomized to one of the two conditions: 1 a high fiber diet and 2 the American Heart Association (AHA diet. In the high fiber diet condition, patients will be given instruction only on achieving daily dietary fiber intake of 30 g or more. In the AHA diet condition, patients will be instructed to make the several dietary changes recommended by the AHA 2006 guidelines. The trial examines participant weight loss and dietary quality as well as changes in components of the metabolic syndrome, inflammatory biomarkers, low-density lipoprotein cholesterol levels, insulin levels, and glycosolated hemoglobin. Potential mediators, i.e., diet adherence and perceived ease of the diet, and the intervention effect on weight change will also be examined. Discussions The purpose of this paper is to outline the study design and methods for testing the simple message of increasing dietary fiber. If the simple dietary approach is found efficacious for weight loss; and, improves dietary quality, metabolic health, and adherence, it might then be used to develop a simple public health message.

    Over the past year, the Incorporated Research Institutions for Seismology (IRIS) Education and Public Outreach (EPO) program has undertaken a new effort to increase the rigor with which it evaluates its programs and products. More specifically we sought to make evaluation an integral part of our EPO staff's work, enable staff to demonstrate why we do the activities we do, enhance the impact or our products and programs, and empower staff to be able to make evidence-based claims. The challenges we faced included a modest budget, finding an applicable approach to both new and legacy programs ranging from formal and informal education to public outreach, and implementing the process without overwhelming staff. The Collaborative Impact Analysis Method (IAM; Davis and Scalice, 2015) was selected as it allowed us to combine the EPO staff's knowledge of programs, audiences and content with the expertise of an outside evaluation expert, through consultations and a qualitative rubric assessing the initial state of each product/program's evaluation. Staff then developed action plans to make incremental improvements to the evaluation of programs over time. We have found that this approach promotes the development of staff knowledge and skills regarding evaluation, provides a common language among staff, increases enthusiasm to collect and share data, encourages discussions of evaluative approaches when planning new activities, and improves each program's ability to capture the intended and unintended effects on the behaviors, attitudes, skills, interests, and/or knowledge of users/participants. We will share the initial IAM Scores for products and programs in the EPO portfolio, along with examples of the action plans for several key products and programs, and the impact that implementing those actions plans has had on our evaluations.

    Full Text Available It follows from the analysis of artillery fire errors that approximately two-thirds of the inaccuracy of indirect artillery fire is caused by inaccuracies in the determination of the meteo parameters included in fire error budget model. Trajectories calculated under non-standard conditions are considered to be perturbed. The tools utilized for the analysis of perturbed trajectories are weighting factor functions (WFFs which are a special kind of sensitivity functions. WFFs are used for calculation of meteo ballistic elements µB (ballistic wind wB, density ρB, virtual temperature τB, pressure pB as well. We have found that the existing theory of WFF calculation has several significant shortcomings. The aim of the article is to present a new, improved theory of generalized WFFs that eliminates the deficiencies found. Using this theory will improve methods for designing firing tables, fire control systems algorithms, and meteo message generation algorithms.

    2012-01-01

    Full Text Available Previous studies demonstrated that choline supply is directly linked to high-fat-diet-induced obesity and insulin resistance in mice. The aim of this study was to evaluate if choline supply could also modulate obesity and insulin resistance caused by a genetic defect. Eight-week-old male ob/ob mice were fed for two months with either choline-deficient or choline-supplemented diet. Tissue weight including fat mass and lean mass was assessed. Intracellular signaling, plasma glucagon and insulin, and glucose and insulin tolerance tests were also investigated. The choline-deficient diet slowed body weight gain and decreased fat mass. Choline deficiency also decreased plasma glucose level and improved glucose and insulin tolerance although fatty liver was exacerbated. Increased adipose lipolytic activity, decreased plasma glucagon and reduced expression of hepatic glucagon receptor were also observed with the choline-deficient diet. Our results demonstrate that a choline-deficient diet can decrease fat mass and improve glucose tolerance in obese and diabetic mice caused by a genetic defect.

    This annual report is in fulfillment of contractual obligations with Bonneville Power Administration (BPA), which is the funding source for the Oregon Department of Fish and Wildlife's (ODFW), Umatilla River Subbasin Fish Habitat Improvement Program (Program). The Program works cooperatively with private landowners to develop long-term restoration agreements, under which, passive and active Habitat Improvement Projects are conducted. Historically, projects have included livestock exclusion fencing (passive restoration) to protect riparian habitats, along with the installation of instream structures (active restoration) to address erosion and improve fish habitat conditions. In recent years, the focus of active restoration has shifted to bioengineering treatments and, more recently, to channel re-design and re-construction aimed at improving fish habitat, through the restoration of stable channel function. This report provides a summary of Program activities for the 2005 calendar year (January 1 through December 31, 2005), within each of the four main project phases, including: (1) Implementation--Pre-Work, (2) Implementation--On Site Development, (3) Operation and Maintenance (O&M), and (4) Monitoring and Evaluation (M&E). This report also summarizes activities associated with Program Administration, Interagency Coordination, and Public Education.

    The purpose of this study was to determine if a sports-specific training program could improve neuromuscular indices in female high school volleyball players. We combined components from a previously published knee ligament injury prevention intervention program for jump and strength training with additional exercises and drills to improve speed, agility, overall strength, and aerobic conditioning. We hypothesized that this sports-specific training program would lead to significant improvements in neuromuscular indices in high school female volleyball players. Thirty-four athletes (age 14.5 years ± 1.0) participated in the supervised 6-week program, 3 d·wk(-1) for approximately 90-120 minutes per session. The program was conducted on the school's volleyball court and weight room facilities. The athletes underwent a video drop-jump test, multistage fitness test, vertical jump test, and sit-up test before and after training. A significant increase was found in the mean VO2max score (p volleyball programs.

    Full Text Available Background: Osteoporosis is a major public health problem affecting the elderly population, particularly women. The objective of the study was to evaluate the effects of adding weight-bearing exercise as opposed to nonweight-bearing programs to the medical treatment of bone mineral density (BMD and health-related quality of life (HRQoL of elderly patients with osteoporosis. Materials and Methods: Participating in the study were 40 elderly osteoporotic patients (27 females and 13 males, with ages ranging from 60 to 67 years, who were receiving medical treatment for osteoporosis. They were assigned randomly into two groups: Group-I: Twenty patients practiced weight-bearing exercises. Group-II: Twenty patients did nonweight-bearing exercises. All patients trained for 45-60 min/session, two sessions/week for 6 months. BMD of the lumbar spine, right neck of femur, and right distal radial head of all patients were measured by dual-energy X-ray absorptiometry before and after both treatment programs. In addition, the QoL was measured by means of the HRQoL "ECOS-16" questionnaire. Results: T-tests proved that mean values of BMD of the lumbar spine, right neck of femur and right distal radial head were significantly increased in both groups with greater improvement in the weight-bearing group. The QoL was significantly improved in both groups, but the difference between them was not significant. Conclusion: Addition of weight-bearing exercise program to medical treatment increases BMD more than nonweight-bearing exercise in elderly subjects with osteoporosis. Furthermore, both weight-bearing and nonweight-bearing exercise programs significantly improved the QoL of patients with osteoporosis.

    BackgroundThe Broselow tape (BT) has been shown to estimate weight poorly primarily because of variations in body habitus. The manufacturers have suggested that a visual assessment of habitus may be used to increase its performance. This study evaluated the ability of habitus-modified models to improve the accuracy thereof.MethodsA post hoc analysis of prospectively collected data from four hospitals in Johannesburg, South Africa, on a population of 1,085 children. Sixteen a priori models generated a modified weight estimation or drug dose based on the BT weight and a gestalt assessment of habitus.ResultsThe habitus-modified method suggested by the manufacturer did not improve the accuracy of the BT. Five dosing and four weight-estimation models were identified that markedly improved dosing and weight estimation accuracy, respectively. The best dosing model improved dosing accuracy (doses within 10% of correct dose) from 52.0 to 69.6% and reduced critical dosing errors from 16.5 to 4.3%. The best weight-estimation model improved accuracy from 59.4 to 81.9% and reduced critical errors from 11.8 to 1.9%.ConclusionThe accuracy of the BT as a drug-dosing and weight-estimation device can be substantially improved by including an appraisal of body habitus in the methodology.Pediatric Research advance online publication, 18 October 2017; doi:10.1038/pr.2017.222.

    Effective approaches that engage men in weight loss and lifestyle change are important because of worldwide increases, including in Canada, in obesity and chronic diseases. Football Fans in Training (FFIT), developed in Scotland, successfully tackled these problems by engaging overweight/obese male football fans in sustained weight loss and positive health behaviours, through program deliveries at professional football stadia. Aims: 1) Adapt FFIT to hockey within the Canadian context and integrate with HealtheSteps™ (evidence-based lifestyle program) to develop Hockey Fans in Training (Hockey FIT); 2) Explore potential for Hockey FIT to help overweight/obese men lose weight and improve other outcomes by 12 weeks, and retain these improvements to 12 months; 3) Evaluate feasibility of recruiting and retaining overweight/obese men; 4) Evaluate acceptability of Hockey FIT; and 5) Conduct program optimization via a process evaluation. We conducted a two-arm pilot pragmatic randomized controlled trial (pRCT) whereby 80 overweight/obese male hockey fans (35-65 years; body-mass index ≥28 kg/m2) were recruited through their connection to two junior A hockey teams (London and Sarnia, ON) and randomized to Intervention (Hockey FIT) or Comparator (Wait-List Control). Hockey FIT includes a 12-week Active Phase (classroom instruction and exercise sessions delivered weekly by trained coaches) and a 40-week Maintenance Phase. Data collected at baseline and 12 weeks (both groups), and 12 months (Intervention only), will inform evaluation of the potential of Hockey FIT to help men lose weight and improve other health outcomes. Feasibility and acceptability will be assessed using data from self-reports at screening and baseline, program fidelity (program observations and coach reflections), participant focus group discussions, coach interviews, as well as program questionnaires and interviews with participants. This information will be analyzed to inform program optimization

    Taiwan has good support systems for obesity prevention and management. The percentage of elementary school students with normal body weight, however, has undergone a sustained decrease to 55%. Many factors are associated with this trend, such as lack of physical activity, dissatisfaction with body image, unbalanced dietary pattern, and unsupportive environment. Even though the rate of overweight and obesity is under control, the rate of underweight among girls has undergone a sustained increase, to 28%. Nurses therefore organized the "Aid students to fit" project, which emphasizes the bipolar issue of overweight and underweight. This national project is sponsored by the Ministry of Education and is expected to establish a beneficial environment, in which students can easily adopt healthy lifestyles and increase self-esteem. The program incorporates the AID triangle concept (Active, Image, Diet) and five strategies for achieving the goals. These strategies are: 1. Develop a persuasive statement to fit in with the philosophies of parents, students and teachers. 2. Set up measurable behavior indices and slogans. (Active life: 210 minutes per week. Image: confident and elegant. Diet: balanced and wise choice of low fat and high fiber foods.) 3. Establish a nation-wide interactive surveillance system for body weight control. 4. Develop an internet system that emphasizes tailored case management for overweight students. 5. Develop a supportive teaching plan, material, and aids to promote a healthy school environment. Five modeling schools, moreover, can be used to demonstrate the program. Educators can also download a free teaching plan, material, and aids at the website for healthy weight management (www.ym.edu.tw/active/aid). The authors brought together scholars from eight universities to accomplish the program. In support of the program, the Taiwan Ministry of Education addressed the new recommendation for physical activity which is to engage in moderate intensity

    Glucagon-like peptide-1 (GLP-1) analogues aid weight loss that improves obesity-associated adipose tissue (AT) dysfunction. GLP-1 treatment may however also directly influence AT that expresses the GLP-1 receptor (GLP-1R). The present study aimed to assess the impact of GLP-1 analogue treatment on subcutaneous AT (SCAT) inflammatory and fibrotic responses, compared with weight loss by calorie reduction (control). Among the 39 participants with Type 2 diabetes recruited, 30 age-matched participants were randomized to 4 months treatment with Liraglutide (n=22) or calorie restriction based on dietetic counselling (n=8). Assessments included clinical characteristics and repeated subcutaneous abdominal AT biopsies. Liraglutide resulted in weight loss in most participants (-3.12±1.72 kg, P=0.007) and significant reduction in visceral AT (VAT). It was more effective in lowering fasting glucose, in comparison with weight loss by dieting. However, tumour necrosis factor-α (TNFA) AT-expression (P=0.0005), macrophage chemoattractant protein-1 (MCP-1) expression (P=0.027) and its serum levels (P=0.048) increased with Liraglutide, suggestive of an inflammatory response unlike in the diet arm in which a trend of lower cluster of differentiation 14 (CD14) expression (P=0.09) was found. Liraglutide treatment also increased expression of factors involved in extracellular matrix (ECM) deposition, transforming growth factor-β (TGFB) and collagen type 1 alpha 1 chain (COL1A1) (TGFB1: before 0.73±0.09 arbitrary units (AU), after 1.00±0.13 AU, P=0.006; COL1A1: 0.84±0.09 AU compared with 1.49±0.26 AU, P=0.026). Liraglutide thus appears to induce an inflammatory response in AT and influences ECM remodelling. Despite its superior effect on glycaemia, Liraglutide does not improve obesity-associated AT dysfunction in subcutaneous tissue. It is yet unclear whether this limits AT storage capacity for lipids. This may be of importance in patients being re-exposed to positive energy

    The Engine Component Improvement (ECI) Program has been initiated in connection with projects designed to reduce the impact of the world-wide energy crisis in the area of aviation. The two parts of the ECI program have the overall objective to identify and quantify the sources and causes of CF6 engine performance deterioration, and to reduce the fuel consumption of CF6 engines through the development and the incorporation of various performance improvement concepts. The CF6 high-bypass turbofan engine was selected as a basis for this effort, since it is expected to be a significant fuel user in commercial revenue service for the next 15 to 20 years. The first part of the ECI program represents the initial step in an effort to achieve a goal of five percent reduction in fuel usage for CF6 engines in the 1979-82 time period. The first performance improvement concept selected is an improved efficiency fan blade. Other improvements are related to a short core exhaust system and an improved high pressure turbine.

    Full Text Available Negative attitudes and beliefs about individuals with obesity (also known as weight bias have negative consequences for physical and mental health for individuals with obesity and impact the quality of care provided by health professionals. A preliminary environmental scan of college and university training programs was conducted consisting of 67 degree and diploma granting programs from 22 institutions in Alberta, targeting programs training future health professionals. Publicly available online course descriptions were examined for weight-related keywords. Keyword frequency was used to determine the extent that coursework addressed weight-related issues. The results suggested that courses are structured to include learning about general health promotion as well as lifestyle factors that may contribute to obesity but may not systematically include learning about weight bias or its potential impact. Our findings highlight the need for further in-depth investigations as well as the need to enhance current curricula in higher education by including information related to weight, obesity and weight bias.

    Obesity rates have steadily increased over the past two decades. To address the epidemic in women, the Health Resources and Services Administration's Maternal and Child Health Bureau, Division of Healthy Start and Perinatal Services (HRSA/MCHB/DHSPS) awarded 14 demonstration grants to community health centers, health departments, universities and community-based organizations in 12 states to develop innovative approaches aimed at reducing the prevalence of overweight and obesity, specifically in women of childbearing age. Grantees implemented modified or existing evidence-based programs (EBP) or promising practices tailored to the geographic locations, cultures and traditional values of the communities. A review of the 15 programs implemented from 2004 to 2007 was conducted using the methodology outlined in the Transparent Reporting of Evaluations with Nonrandomized Designs Statement to identify indicators of successful program implementation. The six indicators identified were: (1) supportive organizational culture with adequate resources and appropriate staff; (2) attention to the needs of the service population; (3) a referral system that links participants to appropriate services; (4) flexible schedules; (5) support for child care and transportation; and (6) formal and informal support systems to keep participants engaged and motivated. Two of the programs that reported improved participant outcomes are available for replication: La Vida Sana, La Vida Feliz in Illinois was designated as a promising practice by the Association of Maternal and Child Health Programs and Sisters in Action in Michigan was rated as a moderate evidence-based program by the Agency for Healthcare Research and Quality.

    Web-based commercial weight loss programs are increasing in popularity. Despite their significant public health potential, there is limited research on the effectiveness of such programs. The objective of our study was to examine weight losses produced by DietBet and explore whether baseline and engagement variables predict weight outcomes. DietBet is a social gaming website that uses financial incentives and social influence to promote weight loss. Players bet money and join a game. All players have 4 weeks to lose 4% of their initial body weight. At enrollment, players can choose to share their participation on Facebook. During the game, players interact with one another and report their weight loss on the DietBet platform. At week 4, all players within each game who lose at least 4% of initial body weight are declared winners and split the pool of money bet at the start of the game. Official weigh-in procedures are used to verify weights at the start of the game and at the end. From December 2012 to July 2013, 39,387 players (84.04% female, 33,101/39,387; mean weight 87.8kg, SD 22.6kg) competed in 1934 games. The average amount bet was US $27 (SD US $22). A total of 65.63% (25,849/39,387) provided a verified weight at the end of the 4-week competition. The average intention-to-treat weight loss was 2.6% (SD 2.3%). Winners (n=17,171) won an average of US $59 (SD US $35) and lost 4.9% (SD 1.0%) of initial body weight, with 30.68% (5268/17,171) losing 5% or more of their initial weight. Betting more money at game entry, sharing on Facebook, completing more weigh-ins, and having more social interactions during the game predicted greater weight loss and greater likelihood of winning (Ps<.001). In addition, weight loss clustered within games (P<.001), suggesting that players influenced each others' weight outcomes. DietBet, a social gaming website, reached nearly 40,000 individuals in just 7 months and produced excellent 4-week weight loss results. Given its reach and

    At present, functional magnetic resonance imaging (fMRI) is one of the most useful methods of studying cognitive processes in the human brain in vivo, both for basic science and clinical goals. Although neuroscience studies often rely on group analysis, clinical applications must investigate single subjects (patients) only. Particularly for the latter, issues regarding the reliability of fMRI readings remain to be resolved. To determine the ability of intra-run variability (IRV) weighting to consistently detect active voxels, we first acquired fMRI data from a sample of healthy subjects, each of whom performed 4 runs (4 blocks each) of self-paced finger-tapping. Each subject's data was analyzed using single-run general linear model (GLM), and each block was then analyzed separately to calculate the IRV weighting. Results show that integrating IRV information into standard single-subject GLM activation maps significantly improved the reliability (p=0.007) of the single-subject fMRI data. This suggests that taking IRV into account can help identify the most constant and relevant neuronal activity at the single-subject level. Copyright © 2015. Published by Elsevier Inc.

  8. The shape of the epiglottis reflects improvement in upper airway obstruction after weight loss.

    2006-07-01

    Obstructive sleep apnea (OSA) is a sleep disorder characterized by recurrent episodes of closure of the upper airway during sleep, and is highly prevalent among overweight individuals. A significant percentage of patients with OSA remain undiagnosed. This condition creates chronic nighttime hypoxemia that can result in significant complications including systemic and pulmonary hypertension, cor pulmonale, and stroke. Polysomnography is still the most widely used method for diagnosing OSA. Studies have shown that in the majority of patients with OSA the airway obstruction involves the retroglossal region. Upon performing esophagogastroduodenoscopy on patients with a wide range of body mass indices (from 21 to 63), we noticed a gradual increase in the concavity of the posterior epiglottal surface as the BMI increases. Upon following some of the patients who underwent laparoscopic gastric banding and lost significant weight, we noticed a dramatic change in the shape of the epiglottis. This reflects a relief in the pressure on the epiglottis created by the collapsing airways in periods of apnea. Thus, the deformity in the shape of the epiglottis reflects the chronic airway collapse in obese patients, and improvement in this deformity after weight loss indicates a relief of the chronic upper airway obstruction.

  9. Weighted Least Squares Techniques for Improved Received Signal Strength Based Localization

    Directory of Open Access Journals (Sweden)

    José R. Casar

    2011-09-01

    Full Text Available The practical deployment of wireless positioning systems requires minimizing the calibration procedures while improving the location estimation accuracy. Received Signal Strength localization techniques using propagation channel models are the simplest alternative, but they are usually designed under the assumption that the radio propagation model is to be perfectly characterized a priori. In practice, this assumption does not hold and the localization results are affected by the inaccuracies of the theoretical, roughly calibrated or just imperfect channel models used to compute location. In this paper, we propose the use of weighted multilateration techniques to gain robustness with respect to these inaccuracies, reducing the dependency of having an optimal channel model. In particular, we propose two weighted least squares techniques based on the standard hyperbolic and circular positioning algorithms that specifically consider the accuracies of the different measurements to obtain a better estimation of the position. These techniques are compared to the standard hyperbolic and circular positioning techniques through both numerical simulations and an exhaustive set of real experiments on different types of wireless networks (a wireless sensor network, a WiFi network and a Bluetooth network. The algorithms not only produce better localization results with a very limited overhead in terms of computational cost but also achieve a greater robustness to inaccuracies in channel modeling.

This prospective study included 707 overweight and obese individuals (mean age, 14 ± 2 years; 57% girls) participating in a 4- to 6-week inpatient weight-loss program, 381 of whom completed a 24-month follow-up. HRQOL, physical activity, sedentary behavior, and BMI were assessed at baseline, at discharge, and at 6, 12, and 24 months after starting therapy. Longitudinal analyses were conducted using repeated-measures mixed models, adjusted for age, sex, and baseline outcome and accounting for attrition over time. All variables improved over treatment and 6-month follow-up (P physical activity explained 30% of the variation in overall HRQOL (P = .01), and change in BMI was not associated with a change in HRQOL. This inpatient weight-loss program was associated with positive changes in HRQOL over the long term, with particular improvements in self-esteem. The results indicate the potential role of physical activity in improving HRQOL without a substantial change in body composition. Copyright © 2014 Elsevier Inc. All rights reserved.

    Prior studies in Drug Courts reported improved outcomes when participants were matched to schedules of judicial status hearings based on their criminological risk level. The current experiment determined whether incremental efficacy could be gained by periodically adjusting the schedule of status hearings and clinical case-management sessions in response to participants' ensuing performance in the program. The adjustments were made pursuant to a priori criteria specified in an adaptive algorithm. Results confirmed that participants in the full adaptive condition (n = 62) were more than twice as likely as those assigned to baseline-matching only (n = 63) to be drug-abstinent during the first 18 weeks of the program; however, graduation rates and the average time to case resolution were not significantly different. The positive effects of the adaptive program appear to have stemmed from holding noncompliant participants more accountable for meeting their attendance obligations in the program. Directions for future research and practice implications are discussed.

    Global market pressures and increasing competition demands that successful companies establish a continual business improvement program as part of implementing its business strategy. Such programs must be driven by the definition of quality from the customer's perspective. This customer quality focus often requires a change in all aspects of the business including products, services, processes and culture. This paper will describe how Atomic Energy of Canada Limited implemented a Continual Business Improvement Program in their Nuclear Laboratories Business Unit. In particular, to review how the techniques were applied to improve the maintenance process and the status of the project. Customer (internal users of the processes at CRL) feedback has shown repeatedly there is dissatisfaction of the maintenance process. Customers complain about jobs not getting done to schedule or being deferred. A project has been launched with the following goals: to improve the maintenance process customer satisfaction and increase trades wrench time by 30 minutes / trade / day. DMAIC (Define-Measure-Analyze-Improve-Control) methodology was applied to find out the Root Cause(s) of the problem, provide solutions, and implement improvements. The expected Operational Benefits include: Executing work efficiently to quality standards and business performance of the site, improve maintenance efficiencies, reduce cycle time for maintenance process and improve process yield, and improve customer and employee satisfaction.

    The current shortfall in effectiveness within conservation biology is illustrated by increasing interest in "evidence-based conservation," whose proponents have identified the need to benchmark conservation initiatives against actions that lead to proven positive effects. The effectiveness of conservation policies, approaches, and evaluation is under increasing scrutiny, and in these areas models of excellence used in business could prove valuable. Typically, conservation programs require years of effort and involve rigorous long-term implementation processes. Successful balance of long-term efforts alongside the achievement of short-term goals is often compromised by management or budgetary constraints, a situation also common in commercial businesses. "Business excellence" is an approach many companies have used over the past 20 years to ensure continued success. Various business excellence evaluations have been promoted that include concepts that could be adapted and applied in conservation programs. We describe a conservation excellence model that shows how scientific processes and results can be aligned with financial and organizational measures of success. We applied the model to two well-documented species conservation programs. In the first, the Po'ouli program, several aspects of improvement were identified, such as more authority for decision making in the field and better integration of habitat management and population recovery processes. The second example, the black-footed ferret program, could have benefited from leadership effort to reduce bureaucracy and to encourage use of best-practice species recovery approaches. The conservation excellence model enables greater clarity in goal setting, more-effective identification of job roles within programs, better links between technical approaches and measures of biological success, and more-effective use of resources. The model could improve evaluation of a conservation program's effectiveness and may be

    New technology offers increased opportunities for weight control. However, it is not clear whether older people with less computer training can make use of this tool. Our objective was to examine how members above the age of 65 years performed in an internet-based behavioral weight loss program, compared to younger members. Data from members (n = 23,233) of an internet-based behavioral weight loss program were analyzed. We restricted our study to active participants accessing the weight club, during a 6-month period (n = 4,440). The number of logins, food intake, and weight records were examined. Participants were divided into age tertiles separately for men and women. The oldest tertile was further subdivided into two groups: above and below the age of 65 years. Participants aged 65 or older were more likely to remain active in the weight club for at least 6 months compared to younger age groups. They had the highest frequency of recordings of food intake and current weight. Among women, those older than 65 years had on average the highest percentage of weight loss (5.6 kg, 6.8%). Men above 65 years of age had the highest number of logins, on average 161 times during the 6-month period. Older participants are performing equally well or even better in an internet-based behavioral weight loss program than younger participants. Internet-based programs could be a promising and attractive option for older adults requiring assistance in losing weight. 2009 S. Karger AG, Basel.

    Physical inactivity is a leading contributor to the burden of disease in men. Social-cognitive theories may improve physical activity (PA) interventions by identifying which variables to target to maximize intervention impact. This study tested the utility of Bandura's social cognitive theory (SCT) to explain men's PA during a 3-month weight loss program. Participants were 204 overweight/obese men (M [SD] age = 46.6 [11.3] years; body mass index = 33.1 [3.5] kg/m2). A longitudinal, latent variable structural equation model tested the associations between SCT constructs (i.e., self-efficacy, outcome expectations, intention, and social support) and self-reported moderate-to-vigorous PA (MVPA) and examined the total PA variance explained by SCT. After controlling for Time 1 cognitions and behavior, the model fit the data well (χ2 = 73.9, degrees of freedom = 39, p weight loss interventions for men may benefit by targeting self-efficacy and intention, but the utility of targeting social support and outcome expectations requires further examination. © The Author(s) 2015.

    This study demonstrates how a multi-theoretical, multilevel process evaluation was used to assess implementation of Families Improving Together (FIT) for weight loss intervention. FIT is a randomized controlled trial evaluating a culturally tailored, motivational plus family-based program on weight loss in African American adolescents and their parents. Social Cognitive, Self Determination, Family Systems theories and cultural tailoring principles guided the conceptualization of essential elements across individual/family, facilitator, and group levels. Data collection included an observational rating tool, attendance records, and a validated psychosocial measure. Results. Attendance records (0=absent, 1=present, criteria=≥70%) indicated that 71.5% of families attended each session. The survey (1=false, 6=true, criteria=≥4.5) indicated that participants perceived a positive group climate (M=5.16, SD=.69). A trained evaluator reported that facilitator dose delivered (0=no, 1=yes, criteria=≥75%) was high (99.6%), and fidelity (1=none to 4=all, criteria=≥3) was adequate at facilitator (M=3.63, SD=.41) and group levels (M=3.35, SD=.49). Five cultural topics were raised by participants related to eating (n=3) and physical activity (n=2) behaviors and were integrated as part of the final curriculum. Discussion. Results identify areas for program improvement related to delivery of multi-theoretical and cultural tailoring elements. Findings may inform future strategies for implementing effective weight loss programs for ethnic minority families. PMID:25614139

    Full Text Available Abstract Objective To compare the accuracy of air displacement plethysmography (ADP and dual energy x-ray absorptionmetry (DXA in tracking changes in body composition after a 16 month weight loss intervention in overweight and obese females. Methods 93 healthy female subjects (38.9 ± 5.7 yr, 159.8 ± 5.6 cm, 76.7 ± 9.9 kg, 30.0 ± 3.4 kg/m2 completed a 16 month weight loss intervention. Eligible subjects attended 15 treatment sessions occurring over the course of 4 months with educational content including topics relating to physical activity and exercise, diet and eating behavior, and behavior modification. In the remaining 12 months, subjects underwent a lifestyle program designed to increase physical activity and improve eating habits. Before and after the intervention, subjects had their percent body fat (%fat, fat mass (FM, and fat-free mass (FFM assessed by DXA and ADP. Results Significant differences (p ≤ 0.001 were found between DXA and ADP at baseline %fat (46.0 % fat vs. 42.0 % fat, FM (35.3 kg vs. 32.5 kg and FFM (40.8 kg vs. 44.2 kg as well as at post intervention for %fat (42.1% fat vs. 38.3 % fat, FM (30.9 kg vs. 28.4 kg and FFM (41.7 kg vs. 44.7 kg. At each time point, ADP %fat and total FM was significantly lower (p ≤ 0.001 than DXA while FFM was significantly higher (p ≤ 0.001. However, both techniques tracked %fat changes similarly considering that there were no differences between the two means. Furthermore, a Bland-Altman analysis was performed and no significant bias was observed, thus demonstrating the ability of ADP to measure body fat across a wide range of fatness. Conclusion At baseline and post weight loss, a significant difference was found between ADP and DXA. However, the results indicate both methods are highly related and track changes in %fat similarly after a weight loss program in overweight and obese females. Additionally, the mean changes in %fat were similar between the two techniques, suggesting

    The recent paper of Ghalehnoee et al., `Improving compact gravity inversion based on new weighting functions', discusses weighting functions for the compact inversion of gravity data. We studied the paper with great interest but deduced that the paper presents minor changes to already published methods. In the manuscript, the model weighting function is the product of three diagonal matrices, that is, a depth weighting matrix, a compactness constraint and a scaling matrix. The authors claim that the scaling matrix is new and introduce the notation `kernel weighting'. Based on our knowledge and understanding of the ideas, not only all the matrix weighting matrices have been used before but also their combination has been used in many published research papers. Here we explain why we believe that the ideas in Ghalehnoee et al. are not new.

    Because universal psychoeducational eating disorder prevention programs have had little success, we developed and evaluated two interventions for high-risk populations: a healthy weight control intervention and a dissonance-based intervention. Adolescent girls (N = 148) with body image concerns were randomized to one of these interventions or to a waitlist control group. Participants completed baseline, termination, and 1, 3, and 6-month follow-up surveys. Participants in both interventions reported decreased thin-ideal internalization, negative affect, and bulimic symptoms at termination and follow-up relative to controls. However, no effects were observed for body dissatisfaction or dieting and effects diminished over time. Results provide evidence that both interventions effectively reduce bulimic pathology and risk factors for eating disturbances. Copyright 2002 by Wiley Periodicals, Inc.

    Full Text Available The world is entering the era of recession when the trend is bearish and market is not so favorable. The capital markets in every major country were experiencing great amount of loss and people suffered in their investment. The Jakarta Composite Index (JCI has shown a great downturn for the past one year but the trend bearish year of the JCI. Therefore, rational investors should consider restructuring their portfolio to set bigger proportion in bonds and cash instead of stocks. Investors can apply modern portfolio theory by Harry Markowitz to find the optimum asset allocation for their portfolio. Higher return is always associated with higher risk. This study shows investors how to find out the lowest risk of a portfolio investment by providing them with several structures of portfolio weighting. By this way, investor can compare and make the decision based on risk-return consideration and opportunity cost as well. Keywords: Modern portfolio theory, Monte Carlo, linear programming

    We investigated the benefits of a cognitive behavior therapy-based exercise program to reduce the dry eye symptoms of office workers. We recruited 11 office workers with dry eye symptoms, aged 31-64 years, who voluntarily participated in group health guidance at a manufacturing company. Participants learned about the role of physical activity and exercise in enhancing wellness and performed an exercise program at home 3 days per week for 10 weeks. We estimated the indexes of body composition, dry eye symptoms, and psychological distress using the Dry Eye-Related Quality of Life Score and the World Health Organization's Subjective Well-Being Inventory questionnaires pre- and postintervention. The 10-week exercise program and the questionnaires were completed by 48.1% (39 of 81) of the participants. Body composition did not change pre- and postintervention. However, the average of the Dry Eye-Related Quality of Life Score scores in participants with subjective dry eye significantly improved after the intervention. Moreover, the World Health Organization's Subjective Well-Being Inventory positive well-being score tended to increase after the intervention. In this study, we showed that a 10-week exercise program improved subjective dry eye symptoms of healthy office workers. Our study suggests that a cognitive behavior therapy-based exercise program can play an important role in the treatment of patients with dry eye disease.

    OBJECTIVE To report the initial changes after quality-improvement programs based on STS-database in a Brazilian hospital. METHODS Since 2011 a Brazilian hospital has joined STS-Database and in 2012 multifaceted actions based on STS reports were implemented aiming reductions in the time of mechanical ventilation and in the intensive care stay and also improvements in evidence-based perioperative therapies among patients who underwent coronary artery bypass graft surgeries. RESULTS All the 947 patients submitted to coronary artery bypass graft surgeries from July 2011 to June 2014 were analyzed and there was an improvement in all the three target endpoints after the implementation of the quality-improvement program but the reduction in time on mechanical ventilation was not statistically significant after adjusting for prognostic characteristics. CONCLUSION The initial experience with STS registry in a Brazilian hospital was associated with improvement in most of targeted quality-indicators. PMID:26934408

    Nuclear power plants mainly use Air Operated Valve(hereinafter referred to as AOV) and Motor Operator Valve(hereinafter referred to as MOV) for protecting system, blocking and controlling flow. Field test(static, dynamic test) results and performance prediction program are used to evaluate if MOV currently installed on nuclear power plants has the operational performance. The improvement of operating performance for Flexible Gate valve was confirmed on changing input variables of performance program(PPM). here are several methods through reviewing design basis, changes operating procedures and maintenance work of stem(or packing, etc.) to improve operating performance of MOV generally installed in the nuclear power plants. This study verified the changes of the MOV operating performance through the improvement of stem and hydraulic parts(seat, guide etc.). Especially, MOV operating performance was much greater improved when the Disk Seat Angle was decreasing. Generally, improvement work to minimize friction of seat, disk and guide is limited and dynamic diagnostic testing has to be performed with change in valve factor for improvement of hydraulic parts.

    Background Web-based commercial weight loss programs are increasing in popularity. Despite their significant public health potential, there is limited research on the effectiveness of such programs. Objective The objective of our study was to examine weight losses produced by DietBet and explore whether baseline and engagement variables predict weight outcomes. Methods DietBet is a social gaming website that uses financial incentives and social influence to promote weight loss. Players bet money and join a game. All players have 4 weeks to lose 4% of their initial body weight. At enrollment, players can choose to share their participation on Facebook. During the game, players interact with one another and report their weight loss on the DietBet platform. At week 4, all players within each game who lose at least 4% of initial body weight are declared winners and split the pool of money bet at the start of the game. Official weigh-in procedures are used to verify weights at the start of the game and at the end. Results From December 2012 to July 2013, 39,387 players (84.04% female, 33,101/39,387; mean weight 87.8kg, SD 22.6kg) competed in 1934 games. The average amount bet was US $27 (SD US $22). A total of 65.63% (25,849/39,387) provided a verified weight at the end of the 4-week competition. The average intention-to-treat weight loss was 2.6% (SD 2.3%). Winners (n=17,171) won an average of US $59 (SD US $35) and lost 4.9% (SD 1.0%) of initial body weight, with 30.68% (5268/17,171) losing 5% or more of their initial weight. Betting more money at game entry, sharing on Facebook, completing more weigh-ins, and having more social interactions during the game predicted greater weight loss and greater likelihood of winning (Psweight loss clustered within games (Pweight outcomes. Conclusions DietBet, a social gaming website, reached nearly 40,000 individuals in just 7 months and produced excellent 4-week weight loss results. Given its reach and potential public health

    Performance improvement in a complex health care environment depends on the cooperation of diverse individuals and groups, allocation of time and resources, and use of effective improvement methods. To address this challenge, we developed an 18-week multidisciplinary training program that would also provide a vehicle for effecting needed improvements, by using a team- and project-based model. The program began in the radiology department and subsequently expanded to include projects from throughout the medical center. Participants were taught a specific method for team-based problem solving, which included (a) articulating the problem, (b) observing the process, (c) analyzing possible causes of problems, (d) identifying key drivers, (e) testing and refining interventions, and (f) providing for sustainment of results. Progress was formally reviewed on a weekly basis. A total of 14 teams consisting of 78 participants completed the course in two cohorts; one project was discontinued. All completed projects resulted in at least modest improvement. Mean skill scores increased from 2.5/6 to 4.5/6 (P success include (a) engagement of frontline staff, (b) teams given authority to make process changes, (c) capable improvement coaches, (d) a physician-director with improvement expertise and organizational authority, (e) capable administrative direction, (f) supportive organizational leaders, (g) weekly progress reviews, (h) timely educational material, (i) structured problem-solving methods, and ( j ) multiple projects working simultaneously. The purpose of this article is to review the program, including the methods and results, and discuss perceived keys to program success. © RSNA, 2016.

    Skills in peer teaching, assessment, and feedback are increasingly documented internationally as required graduate attributes in medicine. Yet these skills are rarely taught in medical schools. We sought to design and deliver a short but effective teacher training (TT) program for medical students that could be easily integrated into the professional development curriculum. This study sought to evaluate such a pilot program, based on student perception. The study took place at a major metropolitan teaching hospital, where 38 medical students were invited to attend a voluntary, newly designed four-module TT program. In total, 23/38 (61%) of invited students attended. Mixed methods were used for evaluation. Questionnaires were completed by 21/23 (91%) of students, and 6/23 (26%) of students participated in a focus group. Students reported that as a result of the program they felt more confident to facilitate small group teaching activities and to provide feedback to peers using the suggested frameworks. Students would like the program to contain more in-depth educational theory and to allow a more time for small group learning activities. They would also like to see opportunities for participation across all clinical schools. The TT program was successful in increasing student awareness of educational theory and practice, thereby improving their confidence in teaching and assessing their peers and making them feel better prepared for their careers as medical practitioners. Key improvements to the program are needed in terms of more in-depth theory and more time spent on small group learning. This might be achieved by complementing the course with e-learning.

    Community-based programs hold significant potential to prevent cardiovascular disease (CVD) risk in youth. We describe here the longitudinal change in several modifiable CVD risk factors after participation in up to 3 years of Fit2Play™, a park-based afterschool program. Children ages 6-15 years old (N = 2261, mean age 9.0 years, 50% Hispanic, 47% non-Hispanic black, 54% male) who participated in Fit2Play™ for either 1-3 school years between 2010 and 2016 had height, weight, 4-site skinfold thicknesses, systolic and diastolic blood pressure, the progressive aerobic cardiovascular endurance run test, and health/wellness knowledge and behavior scores collected at the beginning and end of the school year(s). Effects of length of Fit2Play™ participation on CVD outcomes were assessed via 2-level repeated measures analysis adjusted for child sociodemographics, park, area poverty, and year. Adjusted models showed overweight/obese children who participated in up to 3 years of Fit2Play™ had a mean reduction of 8 mm in skinfold thicknesses; almost 0.5 SD's in BMI z-score; 5 DBP %ile points; 17% reduction in probability of developing hypertension; and a mean increase of 6.4 PACER laps and 17% increase in health/wellness assessment compared to baseline. A dose-response trend was found for years of Fit2Play™ participation and improved CVD risk profile in participating youth. In conclusion, park-based afterschool programs that promote preventive CVD risk strategies can be an equitable, low-cost, high value tool for addressing our national epidemics of obesity, heart disease and diabetes and a rapidly changing healthcare system in need of evidence-based prevention programs.

    Full Text Available The Active Body Control (ABC weight-reduction program is based on telemonitoring of physical activity and nutrition together with telecoaching by weekly counseling letters sent by post or by e-mail. The study presented here reports the results of a 1-year follow-up of 49 patients with the metabolic syndrome who had lost weight with the aid of the ABC program in the preceding year. The weight regain after the second year in patients not receiving any further care (“ABC discontinued” group; n=24 and the potential benefit of continuing with the ABC program with monthly counseling letters (“ABC continued” group; n=25 were investigated. The relative weight changes after the first year had been, respectively, −13.4% and −11.4% in the “ABC discontinued” and “ABC continued” groups, and after the second year they decreased by, respectively, 4.4 and 2.8%. However, this difference in weight regains between the two groups was not statistically significant. It is concluded that three-quarters of the weight loss after 1 year is maintained after the second year. The decision whether to continue with the ABC program after 1 year should be made individually.

    The Clinical Learning Environment Review focuses on the responsibility of the sponsoring institution for quality and patient safety. Very little information is known regarding the status of quality improvement (QI) education during otolaryngology training. The purpose of this survey is to evaluate the extent of resident and faculty participation in QI and identify opportunities for both resident curriculum and faculty development. Cross-sectional survey A 15-item survey was distributed to all 106 otolaryngology program directors. The survey was developed after an informal review of the literature regarding education in QI and patient safety. Questions were directed at the format and content of the QI curriculum, as well as barriers to implementation. There was a 39% response rate. Ninety percent of responding program directors considered education in QI important or very important to a resident's future success. Only 23% of responding programs contained an educational curriculum in QI, and only 33% monitored residents' individual outcome measures. Barriers to implementation of a QI program included inadequate number of faculty with expertise in QI (75%) and competing resident educational demands (90%). Every program director considered morbidity and mortality conferences as an integral component in QI education. Program directors recognize the importance of QI in otolaryngology practice. Unfortunately, this survey identifies a distinct lack of resources in support of these educational goals. The results highlight the need to generate a comprehensive and stepwise approach to QI for faculty development and resident instruction. © American Academy of Otolaryngology—Head and Neck Surgery Foundation 2015.

  18. Recommendations for improvements to program and project management

    1994-01-01

    Oak Ridge National Laboratory (ORNL) has operated with a balanced matrix organization for over sixteen years. Much of the work at the Laboratory is accomplished with good customer satisfaction through programs, projects, and matrix management. During the past several years concerns about program and project management at ORNL have been expressed by both the Department of Energy and ORNL staff. In May 1993 the ORNL Division/Program/Office Directors Caucus chartered a ``fox team`` to identity and to recommend improvements to matrix management that would lead to resolution of these concerns. Nine experienced ORNL staff members served on this Matrix Management Upgrade Solutions Team (MMUST). The MMUST adopted a four-phase approach in which they first gathered information and then developed and proposed recommended actions. In the fourth phase the team was available to support implementation of the recommendations. They began work in June 1993, gathering and evaluating information in biweekly meetings for six months. Recommendations developed in October and November 1993 were presented to ORNL management in December. The MMUST issued three principal recommendations based on their evaluation of the information gathered. They are: Renew and enhance the ORNL management commitment to matrix management, program managers, and project managers; Implement actions to ensure career path parity between the program/project manager family of positions and the technical line manager family of positions across all directorates and divisions; and Clarify and document program/project manager roles, responsibilities, and authorities.

    Full Text Available The  major  objective  of  this  study  was  to  quantify  the  effects  of a  12-week  program  of  weight  bearing  exercises  on  weight  borne  through  the hand and grip pressures in children with hemiplegic cerebral palsy. This study also sought to monitor the change in spasticity immediately following weight-bearing  exercises.  A  quasi-experimental,  one  group  pre-test,  post-test  study  was used. Eleven children with hemiplegic type of cerebral palsy from a special school in KwaZulu Natal participated after fully informed written consent. The intervention consisted of a 12-week program of weight bearing. The Tekscan Grip system was used to quantify weight borne through the hand during extended arm prone and quadruped positions and whilst holding a pencil and a tumbler. The modified Ashworth grading of spasticity was used to monitor spasticity. The data was analysed using the random effects GLS model Wald Chi Square test. Significant increases in contact pressure in extended arms prone (p=0,012 and quadruped (p=0,002 and when holding a pencil (p=0,045 was noted post-test compared to pre-test. Significant increases in contact area of the hand was also noted in prone (p=0,000, quadruped (p=0, 03 at assessment 7 and when holding a pencil (p=0,035.  A significant decrease in spasticity during elbow extension (p=0,004, and wrist flexion (p=0,026 and extension (p=0,004 was noted. An overall significant effect of static weight bearing exercises on weight borne through the hands, grip strength and spasticity justifies the use of static weight-bearing in therapy.

  20. Promoting weight control at the worksite: a pilot program of self-motivation using payroll-based incentives.

    1985-03-01

    Thirty-six individuals participated in a worksite weight-loss program in which the central component was a self-motivation program of biweekly payroll deductions refunded contingent on meeting self-selected weight-loss goals. Half were assigned to early treatment and the remainder to a delayed treatment control group. Nine additional individuals also enrolled at the time of delayed treatment and were included in descriptive analyses of factors associated with weight loss. Results showed low program attrition over 6 months (6%) and mean weight losses (12.3 lb) that are competitive with those obtained in clinical settings. Although not different at baseline, participants in the delayed treatment group lost more than twice as much weight as those in the early treatment condition. This difference was interpreted as either a strong seasonal effect or a critical mass effect related to the proportion of employees at the worksite participating in the program. We conclude that self-motivation programs for health behavior change using the payroll system as an organization framework offer a promising new methodology for promoting healthful behaviors in work settings.

    Few studies have evaluated the effect of adherence to a lifestyle intervention on adolescent health outcomes. The objective of this study was to determine whether adolescent and parental adherence to components of an e-health intervention resulted in change in adolescent body mass index (BMI) and waist circumference (WC) z-scores in a sample of overweight/obese adolescents. In total, 159 overweight/obese adolescents and their parents participated in an 8-month e-health lifestyle intervention. Each week, adolescents and their parents were asked to login to their respective website and to monitor their dietary, physical activity, and sedentary behaviours. We examined participation (percentage of webpages viewed [adolescents]; number of weeks logged in [parents]) and self-monitoring (number of weeks behaviors were tracked) rates. Linear mixed models and multiple regressions were used to examine change in adolescent BMI and WC z-scores and predictors of adolescent participation and self-monitoring, respectively. Adolescents and parents completed 28% and 23%, respectively, of the online component of the intervention. Higher adolescent participation rate was associated with a decrease in the slope of BMI z-score but not with change in WC z-score. No association was found between self-monitoring rate and change in adolescent BMI or WC z-scores. Parent participation was not found to moderate the relationship between adolescent participation and weight outcomes. Developing strategies for engaging and promoting supportive interactions between adolescents and parents are needed in the e-health context. Findings demonstrate that improving adolescents' adherence to e-health lifestyle intervention can effectively alter the weight trajectory of overweight/obese adolescents.

Results Adolescents and parents completed 28% and 23%, respectively, of the online component of the intervention. Higher adolescent participation rate was associated with a decrease in the slope of BMI z-score but not with change in WC z-score. No association was found between self-monitoring rate and change in adolescent BMI or WC z-scores. Parent participation was not found to moderate the relationship between adolescent participation and weight outcomes. Conclusions Developing strategies for engaging and promoting supportive interactions between adolescents and parents are needed in the e-health context. Findings demonstrate that improving adolescents’ adherence to e-health lifestyle intervention can effectively alter the weight trajectory of overweight/obese adolescents.

    Many data mining adopts the form of Artificial Neural Network (ANN) to solve many problems, many problems will be involved in the process of training Artificial Neural Network, such as the number of samples with volume label, the time and performance of training, the number of hidden layers and Transfer function, if the compared data results are not expected, it cannot be known clearly that which dimension causes the deviation, the main reason is that Artificial Neural Network trains compared results through the form of modifying weight, and it is not a kind of training to improve the original algorithm for the extraction algorithm of image, but tend to obtain correct value aimed at the result plus the weigh; in terms of these problems, this paper will mainly put forward a method to assist in the image data analysis of Artificial Neural Network; normally, a parameter will be set as the value to extract feature vector during processing the image, which will be considered by us as weight, the experiment will use the value extracted from feature point of Speeded Up Robust Features (SURF) Image as the basis for training, SURF itself can extract different feature points according to extracted values, we will make initial semi-supervised clustering according to these values, and use Modified K - on his Neighbors (MFKNN) as training and classification, the matching mode of unknown images is not one-to-one complete comparison, but only compare group Centroid, its main purpose is to save its efficiency and speed up, and its retrieved data results will be observed and analyzed eventually; the method is mainly to make clustering and classification with the use of the nature of image feature point to give values to groups with high error rate to produce new feature points and put them into Input Layer of Artificial Neural Network for training, and finally comparative analysis is made with Back-Propagation Neural Network (BPN) of Genetic Algorithm-Artificial Neural Network

  4. Improving Locality for ODE Solvers by Program Transformations

    Full Text Available Runge-Kutta methods are popular methods for the solution of ordinary differential equations and implementations are provided by many scientific libraries. The performance of Runge-Kutta methods depends on the specific application problem to be solved, but also on the characteristics of the target machine. For processors with a memory hierarchy, the locality of data referencing pattern has a large impact on the efficiency of a program. In this paper, we describe program transformations for Runge-Kutta methods resulting in implementations with improved locality behavior for systems of ODEs. The transformations are based on properties of the solution method but are independent from the specific application problem or the specific target machine so that the resulting implementation is suitable as library function. We show that the locality improvement leads to performance gains on different recent microprocessors.

    Unhealthy and inadequate sleep is a common and significant problem impacting absenteeism, presenteeism, health, and productivity. This study aimed at analyzing the effect of a worksite-based healthy sleep program. Retrospective analysis of 53 adult members of a worksite wellness center who participated in an 8-week healthy sleep program and completed pre- and postintervention health behavior questionnaires. Following the intervention participants felt significantly more rested, more confident in their ability to deal with sleep problems, and more knowledgeable about sleep. In addition, they reported a reduction in their stress level, improved quality of life, and increase energy level. These results support the effectiveness of worksite programs designed to promote healthy sleep. Future randomized studies are needed to further investigate the effectiveness and optimal delivery of healthy sleep promotion.

    A number of techniques are employed each year to evaluate the effectiveness of and to identify opportunities for improvement in the Laboratory for Atmospheric Research (LAR) REU program at Washington State University. For example, information gathered from pre-/post-surveys and pre-/post-interviews provides information regarding students' perceptions and levels of experience with the scientific process, career and academic goals, and motivation for joining the REU program. Poster session rubrics assess students' abilities to summarize their experiences in a professional setting. Alumni surveys gauge former participants' perceptions of the REU experience. One seemingly simple and highly useful, but often less documented, component of the evaluation process for program improvement is the use of workshop feedback forms. Weekly workshops are designed to provide students with enhanced knowledge and skills in the area of atmospheric chemistry as well as research design skills, academic and career guidance, and presentation skills. According to previous years' evaluation reports, workshops are largely beneficial to students for learning new skills. Yet, students suggest a number of recommendations that may benefit any REU program, such as: providing slides beforehand to provide a framework for the upcoming workshop, having instructors speak in more student-friendly language, covering higher-level topics, and including more hands-on, instructor-guided practice during the workshops. Thus, workshop feedback forms provide meaningful feedback to increase learning outcomes and enhance the REU student experience. This presentation will offer ideas gathered from over five years of workshop feedback forms that, while somewhat specific to workshops offered for the LAR REU, can offer faculty and PIs insight into the student experience, enhancing their ability to improve programming and achieve greater learning outcomes.

    Social media may have the potential to enhance weight management efforts. However, the acceptability of incorporating this entity into pediatrics is unknown. The objective of this project was to explore patients' and parents' perspectives about developing a Facebook group as a component of a pediatric weight management program. Semistructured interviews were performed between September, 2011, and February, 2012, with patients and parents in a multidisciplinary weight management program. Interviews explored participants' perceptions of potential benefits, concerns, and preferences related to a program-specific Facebook group. Transcripts were reviewed and themes identified. The study concluded when thematic saturation was achieved. Participants (n=32) were largely enthusiastic about the idea of a program-specific Facebook group for adolescents. Most preferred a secret group, where only participants would know of the group's existence or group members' identity. No parents expressed concern about security or privacy related to a program-specific Facebook group; one parent expressed concern about undesirable advertisements. Participants endorsed a variety of ideas for inclusion on the page, including weight loss tips, live chats with providers, quizzes, and an incentive system where participants could gain points for making healthy choices. Many parents requested a separate parent-focused page, an idea that was supported by the adolescents. This study suggests that participants perceive potential benefits from incorporating social media interventions into pediatric weight management efforts. Privacy and security issues do not appear to be major parental concerns. Future work should explore the impact of program-specific social media interventions on outcomes for patients in weight management programs.

    There are currently 1.85 million reproductive-aged women in the United States with diabetes or glucose intolerance. While it is known that postpartum weight retention can lead to obesity and diabetes, particularly among African-American women, little is known about African-American women's preferences for postpartum weight loss programs. Our objective was to explore urban-based African-American women's attitudes toward weight gain, perceived barriers to postpartum weight loss, and preferences for weight intervention strategies. Focus groups of pregnant African-American women (n = 22) were conducted by a race-concordant moderator. Open-ended questions were posed to stimulate discussions which were audio taped and transcribed verbatim. Transcriptions were independently reviewed by two investigators who extracted quotations and coded each statement to identify major themes. The median age of participants was 26 years. Median pre-pregnancy or first trimester body-mass index was 31 kg/m(2). Fifty-seven percent of the women were multiparous and 68% were Medicaid recipients. We identified 16 themes with the majority of participant comments focused on: (1) effect of postpartum depression on motivation to lose weight; (2) strong desire to lose weight; (3) knowledge of adverse effects of obesity; (4) costs of weight loss programs; (5) negative impact of media coverage of successful celebrity postpartum weight loss; (6) limitations of childcare on ability to exercise; and (7) family-centered lifestyle behaviors that promote unhealthy eating. Weight loss interventions for African-American women with postpartum obesity should address psychological effects of childbearing, affordability, and perceptions of body image. Interventions should incorporate family-centered approaches and weight loss maintenance strategies.

    Recently, Cornuéjols and Dawande have considered a special class of 0-1 programs that turns out to be hard for existing IP solvers. One of them is a sorting-based algorithm, based on an idea of Wolsey. In this paper, we show how to improve both the running time and the space requirements...... of this algorithm. The drastic reduction of space needed allows us to solve much larger instances than was possible before using this technique....

    Recent medical guidelines emphasize the importance of actively treating overweight and obesity with diet and lifestyle intervention to achieve ≥ 5% weight loss in a 6-month period. Commercial programs offer one approach provided there is evidence of their efficacy and safety. This study was conducted to evaluate the effectiveness of the Medifast® 4 & 2 & 1 Plan™ on weight loss, body composition and cardiometabolic risk factors in overweight and obese adults. A systematic retrospective chart review of 310 overweight and obese clients following the Medifast 4 & 2 & 1 Plan at one of 21 Medifast Weight Control Centers® was conducted. Data were recorded electronically and key data points were independently verified. The primary endpoint was change from baseline body weight at 12 weeks. Within group paired t-tests were used to examine changes from baseline in a completers population. Differences between gender and age subgroups were examined using bivariate t-tests and mixed model regression analyses. For the primary endpoint at 12 weeks, body weight among completers (n = 185) was reduced by a mean of 10.9 ± 5.6 kg (-10.1%, p weight was reduced by 16.0 ± 7.9 kg (-14.3%). At 12 and 24 weeks, 85% and 96% of those remaining on the plan, respectively, had lost ≥ 5% of their baseline body weight. Lean mass was preserved to within 5% of baseline throughout the 24 weeks, and fat mass represented ≥ 80% of the body weight lost from 12 weeks onward. Men, women, seniors (≥ 65 years), and non-seniors (weight reductions with preservation of lean mass. Significant improvements in blood pressure, pulse and waist-to-hip ratio were observed. Mean weight regain among the subset who entered a formal maintenance phase was 85%. The 4 & 2 & 1 Plan used at Medifast Weight Control Centers was effective for weight loss, preservation of lean mass and improvement in cardiometabolic risk factors. The plan was generally well tolerated in a broad population of overweight and obese

    We examined associations between body weight and plasma 25-hydroxyvitamin D concentration (25OHD) in prediabetes and sought to estimate the impact of adiposity on these associations. The study was conducted in the placebo (n = 1082) and intensive lifestyle (n = 1079) groups of the Diabetes Prevention Program (DPP), a multicenter trial to prevent type 2 diabetes in adults with prediabetes. Weight and 25OHD were measured at baseline, month 6, years 1 and 2. In a subset (n = 584), visceral (VAT) and subcutaneous (SAT) adiposity were assessed by computed tomography at baseline and year 1. In cross-sectional analyses, baseline body weight, total fat, VAT, and SAT were inversely associated with plasma 25OHD concentration after multivariable adjustment. VAT accounted for 40 % [95 % CI 11, 69] of the association of body weight with plasma 25OHD concentration. There was no significant contribution by total fat or SAT. Two-year changes in plasma 25OHD concentration varied inversely with changes in body weight (p weight. Our study found an inverse association between body weight and plasma 25OHD concentration at baseline and over a 2-year period in adults with prediabetes. These findings in the DPP, a weight loss intervention study, raise the possibility that weight loss increases plasma 25OHD concentration. Whether adiposity mediates this association remains inconclusive.

    We consider the problem of outcomes based budget allocations to chronic disease prevention programs across the United States (US) to achieve greater geographical healthcare equity. We use Diabetes Prevention and Control Programs (DPCP) by the Center for Disease Control and Prevention (CDC) as an example. We present a multi-criteria robust weighted sum model for such multi-criteria decision making in a group decision setting. The principal component analysis and an inverse linear programming techniques are presented and used to study the actual 2009 budget allocation by CDC. Our results show that the CDC budget allocation process for the DPCPs is not likely model based. In our empirical study, the relative weights for different prevalence and comorbidity factors and the corresponding budgets obtained under different weight regions are discussed. Parametric analysis suggests that money should be allocated to states to promote diabetes education and to increase patient-healthcare provider interactions to reduce disparity across the US.

    Optimal obesity therapy is a matter of debate. Besides weight reduction, other criteria such as safety and nutritional status are of relevance. Therefore, we compared a favored surgical intervention with the most effective conservative treatment regarding anthropometry and nutritional status. Fifty-four obese patients were included who underwent laparoscopic sleeve gastrectomy (LSG, n = 27) or a 52-week multidisciplinary intervention program (MIP, n = 27) for weight loss. Body weight, body composition assessed by bioelectrical impedance analysis, and serum protein levels were measured before and within 12 months after intervention. After 1 year of observation, excess weight loss was more pronounced following LSG (65 %) compared to MIP (38 %, p weight loss and body fat loss within 1 year, however, induced more pronounced muscle mass and protein loss, possibly requiring particular interventions such as exercise or protein supplements.

    Severe obesity is characterized by low physical activity (PA) and interventions to enhance PA are needed. Participants (45.0 ± 3.9 kg/m2) were randomized to a 6-month standard behavioral weight loss program (SBWL; n = 14) or SBWL+technology (SBWL+TECH; n = 15). Both groups received identical SBWL treatment and SBWL+TECH also received a wearable PA monitor, providing “real-time” feedback, and website access to monitor energy balance. 6-month retention was similar between groups (SBWL: 12/13 versus SBWL+TECH: 11/14 completers; P = 0.19) and adherence to wearing the armband was excellent (91.3% of days). Although differences in PA between groups did not meet conventional thresholds of significance, SBWL+TECH increased their moderate-to-vigorous intensity PA by 132.9 ± 216.8 min/week, which was 3 times greater than SBWL (44.8 ± 124.3 min/week; P = 0.27; Cohen's d = 0.50). There was a trend for SBWL+TECH to self-monitor for a greater proportion of days compared to SBWL (86.2 ± 21.4% versus 71.5 ± 19.4%; P = 0.098; Cohen's d = 0.72). The difference in weight loss between groups was modest (SBWL+TECH: −10.0 ± 7.1% versus SBWL: −7.8 ± 6.7%; P = 0.46). These preliminary findings suggest that PA monitors may be one strategy for increasing PA among the severely obese. Larger, long-term trials are needed. PMID:24379985

    To determine the effectiveness of a structured multidisciplinary non-surgical obesity therapy program on the basis of a temporary low-calorie-diet for 12 weeks, and additional intervention modules to enhance nutritional education, to increase physical activity and to modify eating behavior. Prospective multicenter observational study in obese individuals undergoing a medically supervised outpatient-based 52-week treatment in 37 centers in Germany. A total of 8296 participants with a body mass index (BMI) of >30 kg m(-2) included within 8.5 years. Main outcome measures were body weight loss, waist circumference (WC), blood pressure, quality of life and adverse events. In females, initial body weight was reduced after the 1-year-intervention by 19.6 kg (95% confidence intervals 19.2-19.9 kg) and in males by 26.0 kg (25.2-26.8) according to per protocol analysis of 4850 individuals. Intention-to-treat (ITT) analysis revealed a weight reduction of 15.2 kg (14.9-15.6) in females and 19.4 kg (18.7-20.1) in males. Overall, the intervention resulted in mean reduction in WC of 11 cm; it reduced the prevalence of the metabolic syndrome by 50% and the frequency of hypertension from 47 to 29% of all participants (ITT, all Pobesity grades I-III and obesity-related diseases, and therefore, could be a valuable basis for future weight maintenance strategies required for sustained success.

    To investigate whether sodium supplementation increases weight gain in babies with grade 3 Pierre Robin sequence if their urinary sodium is low. Retrospective review of all medical, dietitian, and nursing notes of babies admitted from 2000 to 2007, inclusive. Tertiary center for cleft care. A total of 33 babies requiring nasogastric and nasopharangeal intubation for Pierre Robin sequence were identified. Those for whom weights could not be measured accurately (n  =  4) were excluded from further study. Urinary sodium was low and weight gain poor in 21 of the remaining 29 babies (72%), and oral sodium supplementation was given to establish and maintain a normal urinary sodium (10 to 20 mmol/L). Mean daily weight gain. The mean daily weight gain of the 18 babies with low urinary sodium admitted in the first few days of life improved from 20 to 34 g (p < .001) following oral sodium supplementation. This gave a mean difference of 14 g (lower quartile  =  6 g, upper quartile  =  25 g, 95% confidence interval  =  20, 90% confidence interval  =  10). The mean daily weight gain of the eight patients who did not require sodium supplementation was 33.6 g. Urinary sodium tests are simple and noninvasive and allow monitoring of urinary sodium. If low, adequate supplementation improved weight gain (p < .001), reversing failure to thrive in babies with severe Pierre Robin sequence. These findings have been unreported previously.

Materials and methods: We recruited 11 office workers with dry eye symptoms, aged 31–64 years, who voluntarily participated in group health guidance at a manufacturing company. Participants learned about the role of physical activity and exercise in enhancing wellness and performed an exercise program at home 3 days per week for 10 weeks. We estimated the indexes of body composition, dry eye symptoms, and psychological distress using the Dry Eye-Related Quality of Life Score and the World Health Organization’s Subjective Well-Being Inventory questionnaires pre- and postintervention. Results: The 10-week exercise program and the questionnaires were completed by 48.1% (39 of 81 of the participants. Body composition did not change pre- and postintervention. However, the average of the Dry Eye-Related Quality of Life Score scores in participants with subjective dry eye significantly improved after the intervention. Moreover, the World Health Organization’s Subjective Well-Being Inventory positive well-being score tended to increase after the intervention. Conclusion: In this study, we showed that a 10-week exercise program improved subjective dry eye symptoms of healthy office workers. Our study suggests that a cognitive behavior therapy-based exercise program can play an important role in the treatment of patients with dry eye disease.

    Low molecular weight heparin (LMWH) has been investigated for the prevention of severe preeclampsia, although the mechanisms of action are unknown. The objective of this study was to investigate the cardiovascular effects of LMWH in pregnant women at high risk of preeclampsia. Pregnant women at high risk of preeclampsia (n=25) and low-risk pregnant controls (n=20) at 22 to 26 weeks' gestation underwent baseline cardiovascular assessments. High-risk women were then randomized to LMWH or saline placebo (30 mg IV bolus and 1 mg/kg subcutaneous dose). Cardiovascular function was assessed 1 and 3 hours post randomization. The in vitro endothelial effects of patient serum and exogenous LMWH on human umbilical venous endothelial cells were determined. High-risk women demonstrated a reduced cardiac output, high resistance hemodynamic profile with impaired radial artery flow-mediated dilation compared with controls. LMWH increased flow-mediated dilation in high-risk women 3 hours after randomization compared with baseline and increased plasma levels of placental growth factor, soluble fms-like tyrosine kinase-1, and myeloperoxidase. Serum from high-risk women impaired endothelial cell angiogenesis and increased PlGF-1 and PlGF-2 transcription compared with serum from low-risk controls. Coexposure of high-risk serum with LMWH improved the in vitro angiogenic response such that it was equivalent to that of low-risk serum and promoted placental growth factor secretion. LMWH improves maternal endothelial function in pregnant women at high risk of developing preeclampsia, possibly mediated through increased placental growth factor bioavailability. © 2016 American Heart Association, Inc.

    Urban Environmental Quality (UEQ) can be treated as a generic indicator that objectively represents the physical and socio-economic condition of the urban and built environment. The value of UEQ illustrates a sense of satisfaction to its population through assessing different environmental, urban and socio-economic parameters. This paper elucidates the use of the Geographic Information System (GIS), Principal Component Analysis (PCA) and Geographically-Weighted Regression (GWR) techniques to integrate various parameters and estimate the UEQ of two major cities in Ontario, Canada. Remote sensing, GIS and census data were first obtained to derive various environmental, urban and socio-economic parameters. The aforementioned techniques were used to integrate all of these environmental, urban and socio-economic parameters. Three key indicators, including family income, higher level of education and land value, were used as a reference to validate the outcomes derived from the integration techniques. The results were evaluated by assessing the relationship between the extracted UEQ results and the reference layers. Initial findings showed that the GWR with the spatial lag model represents an improved precision and accuracy by up to 20% with respect to those derived by using GIS overlay and PCA techniques for the City of Toronto and the City of Ottawa. The findings of the research can help the authorities and decision makers to understand the empirical relationships among environmental factors, urban morphology and real estate and decide for more environmental justice.

    Obesity is a major healthcare problem in youth and their social/electronic media (SEM) use has been described as a risk factor. Though much is known about the newer technologies youth use to communicate, little is known about what is used by those in weight management programs. The aim of this study was to determine what types of SEM, including sedentary and active video games, youth in weight management programs use and which they prefer for communicating with healthcare providers. This was a multisite study using a 24-question online SurveyMonkey® questionnaire. Youth, 12-17 years old, attending pediatric weight management programs at seven participating centers in the Childhood Obesity Multi Program Analysis and Study System network were eligible. There were 292 responders with a mean age of 14.2 years. Fifty-four percent were female, 36% Caucasian, 35% African American, and 33% were Hispanic. Ninety-four percent had access to a computer, 71% had Internet access, and 63% had smartphones. Whereas 87% had at least one gaming system at home, 50% reported they never played sedentary video games (71% of females vs. 25% males; p social media (6%). Face-to-face communication with healthcare providers is the preferred method for youth in pediatric weight management programs. They self-reported video game use less than previously described.

    Full Text Available A group of 35 pregnant reindeer (Rangifcr tarandus was divided into two groups in mid-February. Until calving in May one of the groups (L received lichen ad lib., while the other group (IN received an improved diet, rich in protein and minerals. After calving both groups received the same improved diet. In both groups it was distinguished between young (<3 years and old (>3 years animals. At the start of the experiment the body weight of L-young animals was 58.5 ± 4.6 kg, IN-young 56.2 ± 2.8 kg, L-old 70.3 ± 6.0 kg and IN-old 68.2 ± 4.8 kg. At calving the weights of the same animals were 55.9 ± 4.5 kg (L-young, 68.1 ± 2.5 (IN-young, 70.0 ± 6.9 kg (L-old and 81.6 ± 6.8 kg (IN-old. Birth weight of IN-young calves was 4.5 ± 0.7 kg and of L-young calves 3.7 ± 0.5 kg. Birth weight of IN-old calves was 5.7 ± 0.8 kg and of L-old calves 4.4 ± 0.6 kg. The birth weight of the calves in all groups was correlated to the weight of the female just prior to calving. Growth rates in all but the IN-old group were not different, the IN-old group showing a significantly higher growth rate than the other groups. In mid-September, however, the average body weight for the calves from the L and IN-groups did not differ significantly. Neither chemical composition nor total energy content of the milk differed significantly between the groups. Total mortality in the L-group was 28% as compared to 7% in the IN-group. Two females in the IN-old group had not given birth at the end of the experimental period.Virkningen av bedret ernæring til drektige reinsimler på melkekvalitet, kalvenes fødselsvekt, vekst og dødelighet.Abstract in Norwegian / Sammendrag: En flokk på 35 drektige reinsimler (Rangifer tarandus ble delt i to grupper i midten av februar.

    Since the 1970s, the federal government has spearheaded major national education programs to reduce the burden of chronic diseases in the United States. These prevention and disease management programs communicate critical information to the public, those affected by the disease, and health care providers. The National Diabetes Education Program (NDEP), the leading federal program on diabetes sponsored by the National Institutes of Health (NIH) and the Centers for Disease Control and Prevention (CDC), uses primary and secondary quantitative data and qualitative audience research to guide program planning and evaluation. Since 2006, the NDEP has filled the gaps in existing quantitative data sources by conducting its own population-based survey, the NDEP National Diabetes Survey (NNDS). The NNDS is conducted every 2–3 years and tracks changes in knowledge, attitudes and practice indicators in key target audiences. This article describes how the NDEP has used the NNDS as a key component of its evaluation framework and how it applies the survey results for strategic planning and program improvement. The NDEP's use of the NNDS illustrates how a program evaluation framework that includes periodic population-based surveys can serve as an evaluation model for similar national health education programs.

    Obesity in women with polycystic ovary syndrome (PCOS) negatively affects all clinical features, and a 5 to 10% weight loss has shown promising results on reproductive, metabolic and psychological level. Incorporating a healthy diet, increasing physical activity and changing dysfunctional thought patterns in women with PCOS are key points in losing weight. The biggest challenge in weight management programs is to achieve a reasonable and sustainable weight loss. The aim of this study is to explore whether Cognitive Behavioural Therapy (CBT) by a mental health professional, working in a multidisciplinary team with a dietician and a physical therapist (a three-component intervention), is more effective for weight loss in the long term, within 12 months. We will also explore whether mobile phone applications are effective in supporting behavioural change and sustainable weight loss. The present study is a longitudinal randomized controlled trial (RCT) to study the effectiveness of a three-component 1-year cognitive-behavioural lifestyle intervention in overweight/obese women with PCOS. A total of 210 participants are randomly assigned to three groups: 1) CBT provided by the multidisciplinary team or; 2) CBT provided by the multidisciplinary team and Short Message Service (SMS) or; 3) usual care: encourage weight loss through publicly available services (control group). The primary aim of the 12-month intervention is to explore whether a three-component 1-year cognitive-behavioural lifestyle intervention is effective to decrease weight, when compared to usual care. Secondary outcomes include: the effect of the intervention on the PCOS phenotype, waist circumference, waist to hip ratio, ovulation rates, total testosterone, SHBG, free androgen index (FAI), AMH, hirsutism, acne, fasting glucose, blood pressure and all psychological parameters. Additionally, we assessed time to pregnancy, ongoing pregnancies, clinical pregnancies, miscarriages and birth weight. All

    Full Text Available Introduction. Home visit is the main strategy of primary care by bringing health services to the homes and workplaces of people, which allows knowing the needs of the population firsthand. Thus, home visit by the ATAP represents the first contact of the individual, family and community with the health system, with significant benefits both individually and collectively. This research responds to the need to identify the elements that the home visiting program needs to improve modify or replace in order to maximize the provision of this service.Method. It is a qualitative, observational analytic study. Data were collected through documentary research, key informant interviews and focus group. The analysis was performed from the grounded theory.Results. The main results showed the existence of elements at the level of the health system, home visiting program and the figure of the ATAP that should be reviewed, modified or replaced to the home visit, thus it has bigger and better results for the population and the health system.Conclusion. The Home Visiting Program is strength of the Costa Rican health system to address health inequities. However, it is imperative to make decisions and implementation of actions that promote the improvement and increased results of the home visit at a family and community level.

    It is unclear whether Supplemental Nutrition Assistance Program (SNAP) or National School Lunch Program (NSLP) participation modifies the relationship between food insecurity and obesity in children. Data were included for 4,719 children aged 9-17 years who participated in the National Health and Nutrition Survey between 2003-2004 and 2011-2012. Linear regression was used to examine the relationship between household food security (full, marginal, low, and very low) and BMI percentile. Adjusted models were also stratified by SNAP and NSLP participation. There was no significant overall relationship between household food security and BMI percentile. In SNAP non-participants, there was no apparent overall relationship between BMI percentile and household food security. However, BMI percentile in children from households with low food security was significantly higher than that of children from fully food-secure households (risk difference [RD]=5.95, 95% CI=1.11, 10.80). Among SNAP participants, there was no significant relationship between household food security and BMI percentile. By NSLP participation category, there was a non-significant trend toward increasing BMI percentile with decreasing household food security in those reporting two or fewer (RD=1.75, 95% CI= -0.79, 4.29) and two to three (RD=1.07; 95% CI= -1.74, 3.89) lunches/week. There was no apparent relationship between household food security and BMI percentile in those reporting four or more lunches/week. Although the overall relationship between household food security and weight status in school-aged children was not statistically significant, there was some evidence that the relationship may differ by SNAP or NSLP participation, suggesting the need for more research.

    Full Text Available Alpha-glucosidase inhibitors (AGIs are widely used especially in Asian countries as a treatment option for type 2 diabetes patients with high postprandial glycaemia. However, data from South Asia region is very limited. In order to examine the effect of AGI in real-life setting, 10 PMS/NIS from all over the world from the launch of acarbose to date were pooled in one database and exploratory analysis was performed for glycemic parameters and weight. In total 62,905 patients were pooled from 21 countries and regions. Mean follow up (± SD was 12.2 ± 4.8 weeks (range 0.1-108.9. From South Asia region (India and Pakistan, 8,738 Asian patients were enrolled. Mean PPG decreased from 240.0 and 261.1 mg/dl at baseline by 70.26 ± 65.10 and 82.96 ± 56.59 mg/dl at the last visit in total and South Asian populations, respectively (n = 53,883; n = 7,991, P < 0.0001 for both. Mean FPG decreased from 171.6 and 176.5 mg/dl at baseline by 38.48 ± 47.83 and 49.59 ± 41.41 mg/dl at the last visit in total and South Asian populations, respectively (n = 56,672; n = 7,837, P < 0.0001 for both.

    The Accreditation Council for Graduate Medical Education requires residents to learn quality improvement (QI) methods to analyze, change, and improve their practice. Little is known about how pediatric residency programs design, implement, and evaluate QI curricula to achieve this goal. We sought to describe current QI educational practices, evaluation methods, and program director perceptions through a national survey. A survey of QI curricula was developed, pilot tested, approved by the Association of Pediatric Program Directors (APPD), and distributed to pediatric program directors. Descriptive statistics were used to analyze the data. The response rate was 53% (104 of 197). Most respondents reported presence of a QI curriculum (85%, 88 of 104), including didactic sessions (83%) and resident QI projects (88%). Continuous process improvement was the most common methodology addressed (65%). The most frequent topics taught were "Making a Case for QI" (68%), "PDSA [plan-do-study-act] Cycles" (66%), and "Measurement in QI" (60%). Projects were most frequently designed to improve clinical care (90%), hospital operations (65%), and the residency (61%). Only 35% evaluated patient outcomes, and 17% had no formal evaluation. Programs had a mean of 6 faculty members (standard deviation 4.4, range 2-20) involved in teaching residents QI. Programs with more faculty involved were more likely to have had a resident submit an abstract to a professional meeting about their QI project (9, 92%; P = .003). Barriers to teaching QI included time (66%), funding constraints (39%), and absent local QI expertise (33%). Most PPDs (65%) believed that resident input in hospital QI was important, but only 24% reported resident involvement. Critical factors for success included an experiential component (56%) and faculty with QI expertise (50%). QI curricular practices vary greatly across pediatric residency programs. Although pediatric residency programs commit a fair number of resources to

    The influence of physical activity on metabolic health in overweight dogs is unknown. This study was conducted to evaluate biomarkers of immunometabolic health in relation to changes in physical activity and adiposity. Client-owned overweight dogs participated in a 12-wk intervention based on caloric restriction combined with a training program (fitness and diet [FD] group, n = 8), or caloric restriction alone (diet-only [DO] group, n = 8). Physical activity was monitored by accelerometry. All dogs were fed the same diet and achieved similar weight loss. Fasting blood samples were collected before and after 6- and 12-wk intervention. Insulin resistance was evaluated from plasma insulin and C-peptide as well as homeostasis model assessment. Inflammation and dyslipidemia were evaluated from circulating leptin, adiponectin, C-reactive protein (CRP), monocyte chemoattractant factor-1 (MCP-1), interleukin-8 (IL-8), and cholesterol. Accelerometer counts in both groups were high compared with previous reports of physical activity in overweight dogs. No difference in blood parameters was evident between groups, evaluated by linear mixed-effects model (P > 0.05). Within the groups, the following changes were significant by t-test (P benefits.

    This report describes the work done under contract to Sandia National Labs and to the Department of Energy for improvement of downhole drilling motors. The focus of this program was the development of a better bearing-and-seal assembly that could be used in different kinds of drilling motors in a geothermal environment. Major tasks were: (1) design and construction of seal testing devices, (2) screening and evaluation of candidate seals in a simulated bearing/seal package, (3) tests of the most promising candidates in a full-scale bearing/seal package, and (4) analysis of failed seals after testing. The key results from this program were: (1) identification of seal/shaft/lubricant systems that performed well at high pressure and temperature, (2) identification of other seal designs that should be avoided for similar applications, and (3) evaluation of the test machines' design.

  19. Networked Timetable Stability Improvement Based on a Bilevel Optimization Programming Model

    2014-01-01

    Full Text Available Train timetable stability is the possibility to recover the status of the trains to serve as arranged according to the original timetable when the trains are disturbed. To improve the train timetable stability from the network perspective, the bilevel programming model is constructed, in which the upper level programming is to optimize the timetable stability on the network level and the lower is to improve the timetable stability on the dispatching railway segments. Timetable stability on the network level is defined with the variances of the utilization coefficients of the section capacity and station capacity. Weights of stations and sections are decided by the capacity index number and the degrees. The lower level programming focuses on the buffer time distribution plan of the trains operating on the sections and stations, taking the operating rules of the trains as constraints. A novel particle swarm algorithm is proposed and designed for the bilevel programming model. The computing case proves the feasibility of the model and the efficiency of the algorithm. The method outlined in this paper can be embedded in the networked train operation dispatching system.

    Full Text Available Abstract Background Obesity risk is shared between spouses, yet existing weight loss programs focus on individuals and not the marital dyad. Given the interdependence of weight in couples, weight management outcomes might be improved by targeting joint weight loss and the creation of an interpersonal milieu that supports long-term behavior change. According to Self-Determination Theory (SDT, greater autonomous self-regulation of behaviors, and subsequently better treatment outcomes, are observed in needs supportive environments in which personally meaningful choice is supported and criticism and control are minimized. Correlational analyses confirm these pathways in weight management, with needs support from one’s spouse or partner emerging as a distinct predictor of weight loss success. Research is now needed to establish causal links and to develop and test weight loss interventions designed to facilitate the needs supportive behavior of spouses. Methods Project TEAMS (Talking about Eating, Activity, and Mutual Support is a randomized controlled trial testing a couples-based intervention, grounded in SDT, designed to change the social context of weight loss by training spouses to provide needs support for each other’s eating and physical activity behavior. Sixty-four couples will be randomized to either 6 months of behavioral weight loss treatment informed by SDT (SDT-WL or to 6 months of standard behavioral weight loss treatment (BWL. Couples will attend weekly sessions for 6 months and will be assessed at 0, 3, 6, and 12 months. By bolstering needs support, SDT-WL is predicted to increase autonomous self-regulation and perceived competence and produce greater weight loss and maintenance than standard behavioral treatment. Exploratory analyses will examine the SDT process model prediction that the influence of needs support on treatment outcomes will be mediated by autonomous self-regulation and perceived competence.

    Weight loss fails to resolve obstructive sleep apnea (OSA) in most patients; however, it is unknown as to whether weight loss differentially affects OSA in the supine compared with nonsupine sleeping positions. We aimed to determine if weight loss in obese patients with OSA results in a greater reduction in the nonsupine apnea/hypopnea index (AHI) compared with the supine AHI, thus converting participants into supine-predominant OSA. Post hoc analysis of data from a randomized controlled trial assessing the effect of weight loss (bariatric surgery vs. medical weight loss) on OSA in 60 participants with obesity (body mass index: >35 and sleep study at 2 years. Eight of 37 (22%) patients demonstrated a normal nonsupine AHI (sleep avoidance may cure their OSA.

    Often, in severe obesity, diet and physical activity are not enough to achieve a healthy BMI. Bariatric surgical approach, in particular laparoscopic adjustable gastric banding (LAGB), has encouraging results in terms of weight loss and resolution of obesity-related comorbidities. However, several months after LAGB, some patients are enable to lose weight anymore and don't tolerate a further calibration because of its collateral effects (excessive sense of fullness, heartburn, regurgitation and vomiting). The aim of this study is to identify the potential role of high protein-low carbohydrate ketogenic diet (KD) in managing weight loss in patients who underwent gastric banding and didn't lose weight anymore. 50 patients underwent LAGB between January 2010 and December 2013. In twenty patients (GROUP A) we observed a stop in weight loss so we divided this patients into two groups. One group (group A1: 10 patients) continued to follow a LCD low calorie diet and underwent a further calibration; the other group (group A2: 10 patients) started to follow a KD for the next 8 weeks. Both group resumed a significant weight loss, however group A1 patients reported collateral effects due to calibration and a higher Impact of Weight on Quality of Life - Lite (IWQOL-Lite) that correlates with a lower quality of life than patients following KD. KD can improve the weight loss and quality of life in patients who underwent LAGB and failed at losing more weight allowing a weight loss comparable to that obtained with a further calibration and it is useful to avoid drastic calibrations and their collateral effects.

    In 2013 the Department of Health specified eligibility for bariatric surgery funded by the National Health Service. This included a mandatory specification that patients first complete a Tier 3 medical weight management programme. The clinical effectiveness of this recommendation has not been evaluated previously. Our bariatric centre has provided a Tier 3 programme six months prior to bariatric surgery since 2009. The aim of our retrospective study was to compare weight loss in two cohorts: Roux-en-Y gastric bypass only (RYGB only cohort) versus Tier 3 weight management followed by RYGB (Tier 3 cohort). A total of 110 patients were selected for the study: 66 in the RYGB only cohort and 44 in the Tier 3 cohort. Patients in both cohorts were matched for age, sex, preoperative body mass index and pre-existing co-morbidities. The principal variable was therefore whether they undertook the weight management programme prior to RYGB. Patients from both cohorts were followed up at 6 and 12 months to assess weight loss. The mean weight loss at 6 months for the Tier 3 cohort was 31% (range: 18-69%, standard deviation [SD]: 0.10 percentage points) compared with 23% (range: 4-93%, SD: 0.12 percentage points) for the RYGB only cohort (p=0.0002). The mean weight loss at 12 months for the Tier 3 cohort was 34% (range: 17-51%, SD: 0.09 percentage points) compared with 27% (range: 14-48%, SD: 0.87 percentage points) in the RYGB only cohort (p=0.0037). Our study revealed that in our matched cohorts, patients receiving Tier 3 specialist medical weight management input prior to RYGB lost significantly more weight at 6 and 12 months than RYGB only patients. This confirms the clinical efficacy of such a weight management programme prior to gastric bypass surgery and supports its inclusion in eligibility criteria for bariatric surgery.

A pre-post analysis of metrics of quality of care for diabetes, hypertension, cancer screenings, and connection to mental health care for participants in the ECP was conducted for patients enrolled in ECP for 6 or more months. Patients enrolled in ECP showed statistically significant improvements in hemoglobin A1c, retinal exams, blood pressure measurements, and screenings for colon cancer, and trends toward improvement in diabetic foot exams and screenings for cervical and breast cancer. There was a significant increase in connecting patients to mental health care. This study shows that super-utilizer patients enrolled in the ECP had significant improvements in quality metrics from those prior to enrollment in ECP.

    The purpose of this paper is to propose foundations for a theory of using the Balanced Scorecard (BSC) methodology to improve the strategic view of ergonomics inside the organizations. This approach may help to promote a better understanding of investing on an ergonomic program to obtain good results in quality and production, as well as health maintenance. It is explained the basics of balanced scorecard, and how ergonomists could use this to work with strategic enterprises demand. Implications of this viewpoint for the development of a new methodology for ergonomics strategy views are offered.

    Leptin may influence sweet taste sensitivity. However, there are no reports on an association between the sweet taste threshold and serum leptin levels during weight loss in humans. We investigated the changes in the sweet taste threshold and the serum leptin levels during a weight-loss program, in connection with a leptin receptor polymorphism (Lys109Arg) that may be related to insulin and glucose metabolism. The study included 20 obese, but otherwise healthy, females (mean age: 55 +/- 7 years, body mass index: 26.1 +/- 1.7 kg/m(2)). Participants completed a 12-week weight-loss program based on energy restriction through diet and exercise, which aimed at achieving their optimal weight. The sweet taste threshold was determined according to the whole-mouth gustatory method. Genetic analyses were performed using the allele-specific DNA assay. Serum leptin levels were decreased from 9.2 +/- 4.5 to 7.9 +/- 4.9 ng/ml (p = 0.014) after body weight loss. The sweet taste threshold also decreased significantly from 0.59 +/- 0.42 to 0.22 +/- 0.20% in a solution of sucrose (p = 0.004). In contrast, there were no differences in changes of the threshold between participants with and without the Lys109 allele. A multiple regression analysis revealed that the changes in serum leptin levels were significantly correlated with those in the sweet taste threshold, independent of the initial threshold levels and the Lys109 allele. In conclusion, the serum leptin levels are decreased significantly during a weight-loss program in obese females, which may be associated with the decrease in the sweet taste threshold.

    Brassica napus L. is an important oil crop worldwide and is the main raw material for biofuel. Seed weight and seed size are the main contributors to seed yield. DA1 (DA means big in Chinese) is an ubiquitin receptor and negatively regulates seed size. Down-regulation of AtDA1 in Arabidopsis leads to larger seeds and organs by increasing cell proliferation in integuments. In this study, BnDA1 was down-regulated in B. napus by over expressed of AtDA1R358K , which is a functional deficiency of DA1 with an arginine-to-lysine mutation at the 358th amino acid. The results showed that the biomass and size of the seeds, cotyledons, leaves, flowers and siliques of transgenic plants all increased significantly. In particular, the 1000 seed weight increased 21.23% and the seed yield per plant increased 13.22% in field condition. The transgenic plants had no negative traits related to yield. The candidate gene association analysis demonstrated that the BnDA1 locus was contributed to the seeds weight. Therefore, our study showed that regulation of DA1 in B. napus can increase the seed yield and biomass, and DA1 is a promising target for crop improvement. © 2017 The Authors.

    Childhood obesity is one of the most critical public health problems in the world. It is associated with low neuromuscular function and postural deformities. Whether weight loss can improve postural stability and neuromuscular control, benefit daily activities, or prevent injury is unknown. Therefore, this study attempts to investigate the effect of a 6 month weight management program on postural stability and neuromuscular control among obese children. We will conduct a prospective, single-blind, randomized controlled trial with 120 prepubescent obese children. Participants will be randomly assigned to a weight management group or a control group. The weight management group will participate in a dietary and exercise program. The control group will receive health education. After the intervention, participants will be followed for 6 months with no active intervention. The primary and secondary outcomes will be assessed at the baseline, and after 6 months and 12 months. Primary outcome measures will include body weight, body height, body mass index, waist circumference, hip circumference, and body fat percentage. Secondary outcome measures will include three-dimensional functional biomechanics in different tasks, proprioception tests of the knee and ankle, neuromuscular response of the leg muscles, and muscle strength tests of the knee and ankle. Furthermore, adverse events will be recorded and analyzed. An intention-to-treat analysis will be performed if any participants withdraw from the trial. The important features of this trial include the randomization procedures and large sample size. This study attempts to estimate the effect of weight loss intervention on outcomes, including daily life function, postural stability, and neuromuscular control in prepubescent obese children. Therefore, our results can be useful for obese children, medical staff, and healthcare decision makers. Chinese Clinical Trial Registry ChiCTR-IOB-15005874.

  9. A short executive function training program improves preschoolers’ working memory

    Full Text Available Cognitive training has been shown to improve executive functions in middle childhood and adulthood. However, fewer studies have targeted the preschool years – a time when executive functions undergo rapid development. The present study tested the effects of a short four session executive function training program in 54 four-year-olds. The training group significantly improved their working memory from pre-training relative to an active control group. Notably, this effect extended to a task sharing few surface features with the trained tasks, and continued to be apparent three months later. In addition, the benefits of training extended to a measure of mathematical reasoning three months later, indicating that training executive functions during the preschool years has the potential to convey benefits that are both long-lasting and wide-ranging.

    Improvements in self-image and mood are often reported as outcomes of obesity interventions. However, they may also concurrently influence weight loss, suggesting a reciprocal effect. Although previously reported for overweight women, such relationships were untested in morbidly obese women whose psychosocial responses to treatment may be different, and health-risks greater. Women (N = 161, Meanage = 42 years) with morbid obesity (MeanBMI = 45.1 kg/m(2)) participated in a 6-month, behaviorally based physical activity and nutrition treatment. Significant within-group improvements in weight-loss behaviors (physical activity and eating), weight, body satisfaction, physical self-concept, and depression were found. After controlling for age, mediation analyses indicated that, as a result of the treatment, weight loss was both an outcome and mediator of improvements in body-areas satisfaction and physical self-concept (reciprocal effects), but not depression. Results replicated findings from women with lower degrees of overweight, and suggested that weight-loss treatments emphasize changes in self-perception.

    One-third of US veterans receiving care at Veterans Health Administration (VHA) medical facilities are obese and, therefore, at higher risk for developing multiple chronic diseases. To address this problem, the VHA designed and nationally disseminated an evidence-based weight-management program (MOVE!). The objective of this study was to examine the organizational factors that aided or inhibited the implementation of MOVE! in 10 VHA medical facilities. Using a multiple, holistic case study design, we conducted 68 interviews with medical center program coordinators, physicians formally appointed as program champions, managers directly responsible for overseeing the program, clinicians from the program's multidisciplinary team, and primary care physicians identified by program coordinators as local opinion leaders. Qualitative data analysis involved coding, memorandum writing, and construction of data displays. Organizational readiness for change and having an innovation champion were most consistently the 2 factors associated with MOVE! implementation. Other organizational factors, such as management support and resource availability, were barriers to implementation or exerted mixed effects on implementation. Barriers did not prevent facilities from implementing MOVE! However, they were obstacles that had to be overcome, worked around, or accepted as limits on the program's scope or scale. Policy-directed implementation of clinical weight-management programs in health care facilities is challenging, especially when no new resources are available. Instituting powerful, mutually reinforcing organizational policies and practices may be necessary for consistent, high-quality implementation.

    This study investigated whether participants in a 6-month telephone-based coaching program, who set physical activity, nutrition, and weight loss goals had better outcomes in these domains. Quasi-experimental design. The Australian Get Healthy Information and Coaching Service (GHS), a free population-wide telephone health-coaching service that includes goal setting as a key component of its coaching program. Consenting GHS coaching participants who had completed coaching between February 2009 and December 2012 (n = 4108). At baseline, participants select a goal for the coaching program, and sociodemographic variables are collected. Self-reported weight, height, waist circumference, physical activity, and nutrition-related behaviors are assessed at baseline and 6 months. Descriptive analysis was performed on key sociodemographic variables, and the relationship between goal type and change in health outcomes was assessed using a series of linear mixed models that modeled change from baseline to 6 months. Participants who set goals in relation to weight management and physical activity achieved better results in these areas than those who set alternate goals, losing more than those who set alternate goals (1.5 kg and 0.9 cm in waist circumference) and increasing walking per week (40 minutes), respectively. There was no difference in food-related outcomes for those that set nutrition-related goals. Goal setting for weight management and increasing physical activity in the overweight and obese population, undertaken in a telephone-based coaching program, can be effective. © The Author(s) 2016.

    Very low birth weight (VLBW) preterm infants are vulnerable to growth restriction after discharge due to cumulative protein and energy deficits during their hospital stay and early post-discharge period. The current study evaluated the effectiveness of the preterm infant, post-discharge nutrition (PIN) program to reduce post-discharge growth restriction in Thai VLBW preterm infants. A prospective, non-randomized interventional cohort study was undertaken to assess the growth of 22 VLBW preterm infants who received the PIN program and compared them with 22 VLBW preterm infants who received conventional nutrition services. Infant's growth was recorded monthly until the infants reached six months' corrected age (6-moCA). Intervention infants had significantly greater body weights (p = 0.013) and head circumferences (p = 0.009). Also, a greater proportion of the intervention group recovered their weight to the standard weight at 4-moCA (p = 0.027) and at 6-moCA (p = 0.007) and their head circumference to the standard head circumference at 6-moCA (p = 0.004) compared to their historical comparison counterparts. Enlistment in the PIN program thus resulted in significantly reduced post-discharge growth restriction in VLBW preterm infants. Further research on longer term effects of the program on infant's growth and development is warranted.

    The aim of this work was to reduce the influence of motion on diffusion-weighted MR images of the abdomen by pulse triggering of single-shot sequences. Five healthy volunteers were examined both without and with finger pulse-triggering of a diffusion-weighted single-shot echo planar MR imaging sequence at 1.5 T. Series of diffusion-weighted images were acquired at different phases of the cardiac cycle by varying the time delay between finger pulse and sequence acquisition. The measurements were repeated three times. The diffusion weighted images were analysed by measuring the signal intensities and by determining the ADC values within the spleen, kidney and liver. The magnitude of motion artifacts on diffusion weighted images shows a strong dependence on the trigger delay. The optimum trigger delay is found to be between 500 and 600 ms. For these values the abdominal organs appear homogeneous on all diffusion weighted images and the strongest signal intensities are detected. At optimum triggering the accuracy of the apparent diffusion coefficients is up to 10 times better than without triggering. Moreover, the standard deviation of the repeated measurements is smaller than 12% for all volunteers and for all organs. Without triggering the standard deviation is larger by a factor of 4 on average. Pulse triggering of single-shot sequences leads to significant reduction of motion related artifacts on diffusion weighted images of the abdomen and provides more accurate and reproducible ADC values.

    Weight loss reduces risk factors associated with obesity. However, long-term metabolic improvement remains a challenge. We investigated quantitative gene expression of subcutaneous adipose tissue in obese individuals and its relationship with low calorie diet and long term weight maintenance induced changes in insulin resistance. Three hundred eleven overweight and obese individuals followed a dietary protocol consisting of an 8-week low calorie diet followed by a 6-month ad libitum weight-maintenance diet. Individuals were clustered according to insulin resistance trajectories assessed using homeostasis model assessment of insulin resistance (HOMA-IR) index. Adipose tissue mRNA levels of 267 genes selected for regulation according to obesity, metabolic status and response to dieting was assessed using high throughput RT-qPCR. A combination of discriminant analyses was used to identify genes with regulation according to insulin resistance trajectories. Partial correlation was used to control for change in body mass index. Three different HOMA-IR profile groups were determined. HOMA-IR improved during low calorie diet in the 3 groups. At the end of the 6-month follow-up, groups A and B had reduced HOMA-IR by 50%. In group C, HOMA-IR had returned to baseline values. Genes were differentially expressed in the adipose tissue of individuals according to groups but a single gene, CIDEA, was common to all phases of the dietary intervention. Changes in adipose tissue CIDEA mRNA levels paralleled variations in insulin sensitivity independently of change in body mass index. Overall, CIDEA was up-regulated in adipose tissue of individuals with successful long term insulin resistance relapse and not in adipose tissue of unsuccessful individuals. The concomitant change in adipose tissue CIDEA mRNA levels and insulin sensitivity suggests a beneficial role of adipose tissue CIDEA in long term glucose homeostasis, independently of weight variation.

    2009-01-01

    Objective. Obesity is a significant contributor to oxygen demand and dynamic airway obstruction. The objective of the current study is to determine the long-term success of conservative measures directed toward weight reduction on airway management without respect to specific airway disease etiology. Methods. Patients with chronic airway obstruction secondary anatomic lesions or obstructive sleep apnea were recruited and followed prospectively. Demographics, initial and final weights, diagnosis, and followup information were recorded. Patients were referred to a registered dietician, provided counseling, and started on a weight-loss regimen. Outcome measures were change in body mass index (BMI) and rate of decannulation from weight loss alone. Results. Of fourteen patients, ten remained tracheostomy-dependent and four had high-grade lesions with the potential for improvement in oxygen demand and dynamic airway collapse with weight loss. The mean follow up period was 25 months. The mean change in BMI was an increase of 1.4 kg/m(2) per patient. Conclusions. Conservative measures alone were not effective in achieving weight reduction in the population studied. This may be due to comorbid disease and poor compliance. The promise of decannulation was an insufficient independent motivator for weight loss in this study. Although the theoretical benefits of weight loss support its continued recommendation, the long-term success rate of conservative measures is low. More aggressive facilitated interventions including pharmacotherapy or bariatric surgery should be considered early in the course of treating airway disease complicated by obesity.

    The potential dangers associated with dietary supplements sold for weight loss and muscle building are well documented and increasingly garnering the attention of the media, public, and government leaders. Public health professionals have an opportunity to improve population health in the context of dietary supplement use by translating scientific evidence into action. In this commentary, we discuss the potential to motivate corporate social responsibility (CSR) among manufacturers and retailers of dietary supplements sold for weight loss and muscle building. We examine levers available to public health professionals for generating voluntary corporate self-regulation by reviewing examples from successful CSR initiatives in other domains of public health and offering recommendations highlighting effective advocacy strategies. We encourage public health professionals to use one or multiple advocacy strategies to improve consumer protections for dietary supplements sold for weight loss and muscle building.

    Metatarsus adductus (MA) is a common pediatric foot deformity. Current recommendations suggest observation until 4-6 months, then casting if the deformity persists. Based on our review of the literatures, no randomized controlled trial has been conducted to study the effectiveness of parental stretching in the correction of MA in newborn. Ninety-four newborn feet that were diagnosed as MA by clinical examination were enrolled. Feet were randomized into two groups: observation group and stretching group. Outcome measurements were performed to compare success rate between groups. According to Pearson's χ(2) test, there were no statistically significant differences between groups with regard to the overall success of the parental stretching program ( p = 0.191). There was also no significant difference between groups for mild degree or moderate-to-severe degree ( p = 0.134, p = 0.274, respectively). A more rapid success rate was observed in the stretching group at the first month follow-up, but rate of improvement then decreased. The stretching group tended to have a lower success rate compared to the observation group in moderate-to-severe feet, but the difference was not statistically significant. Parental stretching program found no benefit over observation group in this study. Parental stretching program should not be applied for newborn babies with moderate-to-severe MA as the result from the study appeared to have lower success rate compared to observation group. Observe until 4-6 months, then corrective casting for the persisting deformity is recommended.

    The transitional period from late adolescence to early adulthood is a vulnerable period for weight gain, with a twofold increase in overweight/obesity during this life transition. In the United States, approximately one-third of young adults have obesity and are at a high risk for weight gain. To describe the design and rationale of a National Institute of Diabetes and Digestive and Kidney Diseases (NIDDK) sponsored randomized, controlled clinical trial, the Healthy Body Healthy U (HBHU) study, which compares the differential efficacy of three interventions on weight loss among young adults aged 18-35years. The intervention is delivered via Facebook and SMS Text Messaging (text messaging) and includes: 1) targeted content (Targeted); 2) tailored or personalized feedback (Tailored); or 3) contact control (Control). Recruitment is on-going at two campus sites, with the intervention delivery conducted by the parent site. A total of 450 students will be randomly-assigned to receive one of three programs for 18months. We hypothesize that: a) the Tailored group will lose significantly more weight at the 6, 12, 18month follow-ups compared with the Targeted group; and that b) both the Tailored and Targeted groups will have greater weight loss at the 6, 12, 18month follow-ups than the Control group. We also hypothesize that participants who achieve a 5% weight loss at 6 and 18months will have greater improvements in their cardiometabolic risk factors than those who do not achieve this target. We will examine intervention costs to inform implementation and sustainability other universities. Expected study completion date is 2019. This project has significant public health impact, as the successful translation could reach as many as 20 million university students each year, and change the current standard of practice for promoting weight management within university campus communities.

  8. Improving the Held and Karp Approach with Constraint Programming

    Benchimol, Pascal; Régin, Jean-Charles; Rousseau, Louis-Martin; Rueher, Michel; van Hoeve, Willem-Jan

    Held and Karp have proposed, in the early 1970s, a relaxation for the Traveling Salesman Problem (TSP) as well as a branch-and-bound procedure that can solve small to modest-size instances to optimality [4, 5]. It has been shown that the Held-Karp relaxation produces very tight bounds in practice, and this relaxation is therefore applied in TSP solvers such as Concorde [1]. In this short paper we show that the Held-Karp approach can benefit from well-known techniques in Constraint Programming (CP) such as domain filtering and constraint propagation. Namely, we show that filtering algorithms developed for the weighted spanning tree constraint [3, 8] can be adapted to the context of the Held and Karp procedure. In addition to the adaptation of existing algorithms, we introduce a special-purpose filtering algorithm based on the underlying mechanisms used in Prim's algorithm [7]. Finally, we explored two different branching schemes to close the integrality gap. Our initial experimental results indicate that the addition of the CP techniques to the Held-Karp method can be very effective.

    Physiotherapy is integral to modern trauma care. Early physiotherapy and mobility have been shown to improve outcomes in patients with isolated injuries; however, the optimal intensity of physiotherapy in the multitrauma patient population has not yet been examined. The primary aim of this study was to determine whether an intensive physiotherapy program resulted in improved inpatient mobility. We conducted a single-center prospective randomized controlled study of 90 consecutive patients admitted to the Alfred Hospital (a Level 1 trauma center) in Australia between October 2011 and June 2012 who could participate in ward-based physiotherapy. Participants were allocated to either usual care (daily physiotherapy treatment, approximately 30 minutes) or intensive physiotherapy (usual care plus two additional 30-minute treatments each day). The primary outcome measure was the modified Iowa Level of Assistance (mILOA) score, collected by a blinded assessor at Days 3 and 5 (or earlier if discharged). Secondary measures included physical readiness for discharge, hospital and rehabilitation length of stay, a patient confidence and satisfaction scale, and quality of life at 6 months. Groups were comparable at baseline. Participants in the intensive physiotherapy group achieved significantly improved mILOA scores on Day 3 (median, 7 points compared with 10 points; p = 0.02) and Day 5 (median, 7.5 points compared with 16 points; p = 0.04) and were more satisfied with their care (p = 0.01). There was no difference between groups in time to physical readiness, discharge destination, length of stay, or quality-of-life measures. Intensive physiotherapy resulted in improved mobility in trauma inpatients. Further studies are required to determine if specific groups benefit more from intensive physiotherapy and if this translates to long-term improvements in outcomes. Therapeutic study, level 1.

    The United States is experiencing an epidemic of obesity among both adults and children. Approximately 35 percent of women and 31 percent of men age 20 and older are considered obese, as are about one-quarter of children and adolescents. While government health goals for the year 2000 call for no more than 20 percent of adults and 15 percent of adolescents to be obese, the prevalence of this often disabling disease is increasing rather than decreasing. Obesity, of course, is not increasing because people are consciously trying to gain weight. In fact, tens of millions of people in this country are dieting at any one time; they and many others are struggling to manage their weight to improve their appearance, feel better, and be healthier. Many programs and services exist to help individuals achieve weight control. But the limited studies paint a grim picture: those who complete weight-loss programs lose approximately 10 percent of their body weight, only to regain two-thirds of it back within 1 year and almost all of it back within 5 years. These figures point to the fact that obesity is one of the most pervasive public health problems in this country, a complex, multifactorial disease of appetite regulation and energy metabolism involving genetics, physiology, biochemistry, and the neurosciences, as well as environmental, psychosocial, and cultural factors. Unfortunately, the lay public and health-care providers, as well as insurance companies, often view it simply as a problem of willful misconduct--eating too much and exercising too little. Obesity is a remarkable disease in terms of the effort required by an individual for its management and the extent of discrimination its victims suffer. While people often wish to lose weight for the sake of their appearance, public health concerns about obesity relate to this disease's link to numerous chronic diseases that can lead to premature illness and death. The scientific evidence summarized in Chapter 2 suggests

    To examine the efficacy of an interactive, child-centred and family-based program in promoting healthy weight and healthy lifestyles in Chinese American children. A randomized controlled study of a culturally sensitive behavioral intervention. Sixty-seven Chinese American children (ages, 8-10 years; normal weight and overweight) and their families. Anthropometry, blood pressure, measures of dietary intake, physical activity, knowledge and self-efficacy regarding physical activity and diet at baseline and 2, 6 and 8 months after baseline assessment. Linear mixed modeling indicated a significant effect of the intervention in decreasing body mass index, diastolic blood pressure and fat intake while increasing vegetable and fruit intake, actual physical activity and knowledge about physical activity. This interactive child-centred and family-based behavioral program appears feasible and effective, leading to reduced body mass index and improved overweight-related health behaviors in Chinese American children. This type of program can be adapted for other minority ethnic groups who are at high risk for overweight and obesity and have limited access to programs that promote healthy lifestyles.

    Deficits in growth observed in HIV-infected children in resource-poor settings can be reversed with antiretroviral treatment (ART). However, many of the studies have been conducted in urban areas with older pediatric populations. This study was undertaken to evaluate growth patterns after ART initiation in a young pediatric population in rural Zambia with a high prevalence of undernutrition. Between 2007 and 2009, 193 HIV-infected children were enrolled in a cohort study in Macha, Zambia. Children were evaluated every 3 months, at which time a questionnaire was administered, height and weight were measured, and blood specimens were collected. Weight- and height-for-age z-scores were constructed from WHO growth standards. All children receiving ART at enrollment or initiating ART during the study were included in this analysis. Linear mixed effects models were used to model trajectories of weight and height-for-age z-scores. A high proportion of study children were underweight (59%) and stunted (72%) at treatment initiation. Improvements in both weight- and height-for-age z-scores were observed, with weight-for-age z-scores increasing during the first 6 months of treatment and then stabilizing, and height-for-age z-scores increasing consistently over time. Trajectories of weight-for-age z-scores differed by underweight status at treatment initiation, with children who were underweight experiencing greater increases in z-scores in the first 6 months of treatment. Trajectories of height-for-age z-scores differed by age, with children older than 5 years of age experiencing smaller increases over time. Some of the effects of HIV on growth were reversed with ART initiation, although a high proportion of children remained underweight and stunted after two years of treatment. Partnerships between treatment and nutrition programs should be explored so that HIV-infected children can receive optimal nutritional support.

    Background Overweight status after breast cancer treatment may increase a woman’s risk for recurrent disease and/or early onset cardiovascular disease. Green tea has been proposed to promote weight loss and favourably modify glucose, insulin and blood lipids. This pilot study tested the effect of daily decaffeinated green tea consumption for 6 months on weight and body composition, select metabolic parameters, and lipid profiles in overweight breast cancer survivors. Methods The effect of daily decaffeinated green tea intake on weight, body composition and changes in resting metabolic rate, energy intake, glucose, insulin, HOMA-IR, and lipids was evaluated in overweight breast cancer survivors. Participants had a mean weight of 80.2 kg; BMI 30.1 kg/m2; and body fat 46.4%. Participants (N=54) were randomised to 960 mL decaffeinated green or placebo tea daily for 6 months. Results Average tea intake among study completers (N=39) was 5952 ± 1176 mL/week and was associated with a significant reduction in energy intake (P =0.02). Change in body weight of −1.2 kg (green tea) versus + 0.2 kg (placebo) suggests a weight change effect, but was not statistically significant. Decaffeinated green tea intake was associated with elevated HDL levels (P=0.003) and non-significant improvements in the HOMA-IR (−1.1±5.9: green tea; +3.2±7.2: herbal) and the HDL/LDL ratio. Conclusions Intake of decaffeinated green tea for 6 months was associated with a slight reduction in body weight and improved HDL and glucose homeostasis in overweight breast cancer survivors.

    To calculate the percent weight reduction required to achieve minimal clinically important improvement (MCII) in health-related quality of life (HRQOL). Secondary data analysis from the longitudinal cohort of a single-blinded, cluster-randomized community trial to test the efficacy of the faith-based adaptation of the Diabetes Prevention Program. African-American churches. This study included 472 congregants with a body mass index of ≥25 and fasting plasma glucose<126mg/dl. Percent weight reduction required to achieve the MCII in HRQOL measured by two instruments, SF-12 and EQ-5D, one year following baseline. The percent weight reduction required to achieve established MCII in SF-12 Physical Component Summary (PCS), SF-12 Mental Component Summary (MCS), and EQ-5D Health Status (HS) at one-year follow-up were calculated using fitted linear regression models. In addition to models for the total sample, we generated models, stratified by baseline BMI, PCS, and HS, to calculate the percent weight reduction required to achieve MCII in HRQOL for those most in need of weight reduction and those in need of improved HRQOL. The percent weight reduction was a significant predictor of improvement in the SF-12PCS and the EQ-5DHS but not SF-12MCS. To achieve a MCII in SF-12PCS and EQ-5DHS, 18% and 30% weight reductions were required, respectively. A smaller percent weight reduction was required when the baseline BMI was ≥40. Improvements in HRQOL among African-American congregants seeking weight reduction required more than the 3-5% weight reduction associated with improvements in physical health.

    Purpose A cancer and fertility program was established at a large cancer center to support clinicians in discussing treatment-related fertility risks and fertility preservation (FP) options with patients and in referring patients to reproductive specialists. The program provides resources, clinician education, and fertility clinical nurse specialist consultation. This study evaluated the program’s impact on patient satisfaction with information received. Patients and Methods Retrospective cross-sectional surveys assessed satisfaction before (cohort 1 [C1]) and after (cohort 2 [C2]) program initiation. Questionnaires were investigator-designed, gender-specific, and anonymous. Results Most C1 (150 males, 271 females) and C2 (120 males, 320 females) respondents were 2 years postdiagnosis; the most frequently reported cancers were testicular, breast, and lymphoma. A significant difference in satisfaction with the amount of information received was seen between C1 and C2. For males, satisfaction with information on fertility risks was high in both cohorts but significantly greater in C2 for information on sperm banking (χ2 = 9.3, P = .01) and finding a sperm bank (χ2 = 13.3, P = .001). For females, satisfaction with information was significantly greater in C2 for information on fertility risks (χ2 = 62.1, P < .001), FP options (χ2 = 71.9, P < .001), help with decision making (χ2 = 80.2, P < .001), and finding a reproductive endocrinologist (χ2 = 60.5, P < .001). Among patients who received and read information materials, 96% of males and 99% of females found them helpful. Among C2 females, fertility clinical nurse specialist consultation was associated with significantly greater satisfaction with information on FP options (χ2 = 11.2, P = .004), help with decision making (χ2 = 10.4, P = .006), and finding a reproductive endocrinologist (χ2 = 22.6, P < .001), with 10% reporting lack of knowledge as a reason for not pursuing FP.

  18. Health-weighted Composite Quality Metrics Offer Promise to Improve Health Outcomes in a Learning Health System.

    Health system leaders sometimes adopt quality metrics without robust supporting evidence of improvements in quality and/or quantity of life, which may impair rather than facilitate improved health outcomes. In brief, there is now no easy way to measure how much "health" is conferred by a health system. However, we argue that this goal is achievable. Health-weighted composite quality metrics have the potential to measure "health" by synthesizing individual evidence-based quality metrics into a summary measure, utilizing relative weightings that reflect the relative amount of health benefit conferred by each constituent quality metric. Previously, it has been challenging to create health-weighted composite quality metrics because of methodological and data limitations. However, advances in health information technology and mathematical modeling of disease progression promise to help mitigate these challenges by making patient-level data (eg, from the electronic health record and mobile health (mHealth) more accessible and more actionable for use. Accordingly, it may now be possible to use health information technology to calculate and track a health-weighted composite quality metric for each patient that reflects the health benefit conferred to that patient by the health system. These health-weighted composite quality metrics can be employed for a multitude of important aims that improve health outcomes, including quality evaluation, population health maximization, health disparity attenuation, panel management, resource allocation, and personalization of care. We describe the necessary attributes, the possible uses, and the likely limitations and challenges of health-weighted composite quality metrics using patient-level health data.

    To examine the effect of a 12-week slow movement resistance training using body weight as a load (SRT-BW) on muscle mass, strength, and fat distribution in healthy elderly people. Fifty-three men and 35 women aged 70 years old or older without experience in resistance training participated, and they were randomly assigned to a SRT-BW group or control group. The control group did not receive any intervention, but participants in this group underwent a repeat measurement 12 weeks later. The SRT-BW program consisted of 3 different exercises (squat, tabletop push-up, and sit-up), which were designed to stimulate anterior major muscles. Initially, these exercises were performed by 2 sets of 10 repetitions, and subsequently, the number of repetitions was increased progressively by 2 repetitions every 4 weeks. Participants were instructed to perform each eccentric and concentric phase of movement slowly (spending 4 seconds on each movement), covering the full range of motion. We evaluated muscle mass, strength, and fat distribution at baseline and after 12 weeks of training. Changes over 12 weeks were significantly greater in the SRT-BW group than in the control group, with a decrease in waist circumference, hip circumference, and abdominal preperitoneal and subcutaneous fat thickness, and an increase in thigh muscle thickness, knee extension strength, and hip flexion strength. In conclusion, relatively short-term SRT-BW was effective in improving muscle mass, strength, and fat distribution in healthy elderly people. © 2017 John Wiley & Sons A/S.

    Full Text Available Structural brain networks estimated from diffusion MRI (dMRI via tractography have been widely studied in healthy controls and patients with neurological and psychiatric diseases. However, few studies have addressed the reliability of derived network metrics both node-specific and network-wide. Different network weighting strategies (NWS can be adopted to weight the strength of connection between two nodes yielding structural brain networks that are almost fully-weighted. Here, we scanned five healthy participants five times each, using a diffusion-weighted MRI protocol and computed edges between 90 regions of interest (ROI from the Automated Anatomical Labeling (AAL template. The edges were weighted according to nine different methods. We propose a linear combination of these nine NWS into a single graph using an appropriate diffusion distance metric. We refer to the resulting weighted graph as an Integrated Weighted Structural Brain Network (ISWBN. Additionally, we consider a topological filtering scheme that maximizes the information flow in the brain network under the constraint of the overall cost of the surviving connections. We compared each of the nine NWS and the ISWBN based on the improvement of: (a intra-class correlation coefficient (ICC of well-known network metrics, both node-wise and per network level; and (b the recognition accuracy of each subject compared to the remainder of the cohort, as an attempt to access the uniqueness of the structural brain network for each subject, after first applying our proposed topological filtering scheme. Based on a threshold where the network level ICC should be >0.90, our findings revealed that six out of nine NWS lead to unreliable results at the network level, while all nine NWS were unreliable at the node level. In comparison, our proposed ISWBN performed as well as the best performing individual NWS at the network level, and the ICC was higher compared to all individual NWS at the node

    Few evaluations of the Veterans Health Administration Motivating Overweight/Obese Veterans Everywhere (MOVE!) weight management program have assessed 6-month weight change or factors associated with weight change by gender. Analysis of administrative data from a national sample of veterans in the VA MOVE! A total of 62,882 participants were included, 14.6% were women. Compared with men, women were younger (49.6 years [standard deviation, SD, 10.8] vs. 59.3 years [SD, 9.8], p stress disorder (26.0% vs. 22.4%, p women was lower than men (5.6 [SD, 5.3] vs. 6.0 [SD, 5.9], p Women, compared with men, reported lower rates of being able to rely on family or friends (35.7% vs. 40.8%, p women was -1.5% (SD, 5.2) and for men was -1.9% (SD, 4.8, p women (body-mass index [BMI] >25 kg/m(2)) compared with men (BMI >25 kg/m(2); odds ratio, 1.05 [95% confidence interval, 0.99-1.11; p = 0.13]). Women veterans lost less weight overall compared with men. There was no difference in the odds of achieving clinically significant weight loss by gender. The majority of women and men enrolled lost <5% weight despite being enrolled in a lifestyle intervention. Future studies should focus on identifying program- and participant-level barriers to weight loss.

    Body weight, shape and body image were assessed in 16 males and 18 females before and after both 6 x 40 mins exercise and 6 x 40 mins reading. Over both conditions, body weight and shape did not change. Various aspects of body image, however, improved after exercise compared to before, while no changes were found over reading. These findings have implications for exercise promotion where a possible role for body image in exercise adherence is suggested, and confirm current theories of body image, where changes in body image are mediated by body perceptions as opposed to actual body indices.

    Several studies have shown that e-mail counseling improves weight loss achieved in self-directed Internet programs. Computer-tailored feedback offers a population-based alternative to human e-mail counseling. One hundred ninety-two adults, aged 49.2 +/- 9.8 years, having a body mass index (calculated as weight in kilograms divided by height in meters squared) of 32.7 +/- 3.5, were randomized to 1 of 3 Internet treatment groups: No counseling, computer-automated feedback, or human e-mail counseling. All participants received 1 weight loss group session, coupons for meal replacements, and access to an interactive Web site. The human e-mail counseling and computer-automated feedback groups also had access to an electronic diary and message board. The human e-mail counseling group received weekly e-mail feedback from a counselor, and the computer-automated feedback group received automated, tailored messages. Retention was 82% at 3 months and 80% at 6 months for all 3 groups. At 3 months, completers in both the computer-automated feedback (-5.3 +/- 4.2 kg) and human e-mail counseling (-6.1 +/- 3.9 kg) groups had significantly greater weight losses compared with the no counseling group (-2.8 +/- 3.5 kg) and these groups did not differ from each other. At 6 months, weight losses were significantly greater in the human e-mail counseling group (-7.3 +/- 6.2 kg) than in the computer-automated feedback (-4.9 +/- 5.9 kg) or no counseling (-2.6 +/- 5.7 kg) groups. Intent-to-treat analyses using single or multiple imputation techniques showed the same pattern of significance. Providing automated computer-tailored feedback in an Internet weight loss program was as effective as human e-mail counseling at 3 months. Further research is needed to improve the efficacy of automated computer-tailored feedback as a population-based weight loss approach.

    Defining the quality of the university education system is not easy. Institutions of higher education, through curriculum are hoped to provide the knowledge, wisdom and personality of students. It is questionable of how far Quality and Productivity Improvement Program (PPKP) are capable to ensure the courses offered relevant and effective in preparing the students for job market. The effectiveness of a university to undertake responsibilities and the impact given to students even after they graduate can be a measure of education quality at university. So, the quality of education can be enhanced and improved from time to time. In general, this study is aims to determine the effectiveness of PPKP's education system from the perspective of their alumni as well as their satisfaction and the importance level based on how PPKP be able to meet their needs. In overall, summary of open-ended questions from the questionnaire, Importance-Performance analysis and correlation analysis were conducted for this study. Based on result, it appears that there are still some deficiencies that can be improve, particularly in terms of teaching skills and PPKP's relationships with external organizations to enable knowledge be channel effectively. Importance-Performance analysis highlights some topics or courses that should be offered by PPKP based on their importance in industrial practice. Summary of the results of correlation analysis was found that women are more positive and not too demanding compared to men. In addition, it is found that the responsibilities and workload of the older generations, higher income and a high level of experience demands them to use and practice what they have learned during their studies at PPKP. Results of this study are hoped could be used to improve the quality of education system at PPKP.

    Human adipose tissue is not only a storage organ but also an active endocrine organ to release adipokines. This study was conducted to investigate the relationship among serum taurine and adipokine levels, and body composition during 8-week human body weight control program in obese female college students. The program consisted of diet therapy, exercise, and behavior modification. After the program, body weight, body fat mass, percent body fat, and body mass index (BMI) were significantly decreased. Serum triglyceride (TG), total cholesterol (TC), and low-density lipoprotein cholesterol (LDL-C) levels were significantly decreased. Also serum adiponectin level was significantly increased and serum leptin level was significantly decreased. There were no differences in serum taurine and homocysteine levels. The change of serum adiponectin level was positively correlated with change of body fat mass and percent body fat. These results may suggest that body fat loss by human body weight control program is associated with an increase in serum adiponectin in obese female college students. Therefore, further study such as taurine intervention study is needed to know more exact correlation between dietary taurine intake and serum adipokines or body composition.

    Full Text Available Abstract Background Previous studies have demonstrated positive effects of short-term, intensive weight-loss programs in obese children. Objectives We evaluated the long-term effects of a non-intensive weight management program on the BMI, glycemic measures and lipid profiles of obese youth. Methods Retrospective chart review of 61 obese children followed at our Weight Management Center. During visits, dietary changes and regular physical activity were recommended. Anthropometric and laboratory parameters were evaluated. Results At the initial visit, the mean age was 11.1 ± 2.6 years. The follow-up period was 47.3 ± 11.1 months; the number of outpatient visits per year (OV/yr was 2.9 ± 0.9. At the end of the follow-up, the whole group exhibited decreased BMI z-score and LDL-cholesterol when compared to the initial visit. In the subset of subjects in whom OGTT was performed, 2-hour glucose and peak insulin were decreased. Compared to children with ≤ 2 OV/year, those with > 2 OV/year (3.19 ± 0.7 exhibited a significant decrease in their BMI z-score, LDL-cholesterol, 2-hour glucose, and peak insulin. Conclusions Our study suggests that a periodical (~ 3 OV/yr evaluation in a non-intensive, long-term weight management program may significantly improve the degree of obesity and cardiovascular risk factors in childhood.

    Grey world algorithm is a simple but widely used global white balance method for color cast images. However, this algorithm only assumes that the mean values of the R, G, and B components tend to be equal, which may lead to false alarms in some normal images with large areas of single color background, for example, images in ocean background. Another defect is that grey world algorithm may cause luminance variations in the channels having no cast. We note that though different in mean values, standard deviations of the three channels are supposed to converge in color cast images, which is not suitable for those false alarms. Based on this discrepancy, through a mathematical manipulation both on mean values and standard deviations of the three channels, a novel color correction model is proposed by weighting the gain coefficients in grey world model. All the three weighted gain coefficients in the proposed model tend to be 1 on images containing large single color regions so as to avoid false alarms. For the color cast images, the channel existing color cast is given a weighted gain coefficient much less than 1 to correct color cast, while the other two channels are distributed weighted gain coefficients approximately equal to 1 thus to ensure that the proposed model has little negative effects on channels with no color cast. Experiments show that our model presents better performance in color correction.

    There has been a long-standing desire to implement a multi-institutional, multispecialty program to address surgical quality improvement for children. This report documents results of the initial phase of the American College of Surgeons National Surgical Quality Improvement Program Pediatric. From October 2008 to December 2009, patients from 4 pediatric referral centers were sampled using American College of Surgeons National Surgical Quality Improvement Program methodology tailored to children. A total of 7,287 patients were sampled, representing general/thoracic surgery (n = 2,237; 30.7%), otolaryngology (n = 1,687; 23.2%), orthopaedic surgery (n = 1,367; 18.8%), urology (n = 893; 12.3%), neurosurgery (n = 697; 9.6%), and plastic surgery (n = 406; 5.6%). Overall mortality rate detected was 0.3% and 287 (3.9%) patients had postoperative occurrences. After accounting for demographic, preoperative, and operative factors, occurrences were 4 times more likely in those undergoing inpatient versus outpatient procedures (odds ratio [OR] = 4.71; 95% CI, 3.01-7.35). Other factors associated with higher likelihood of postoperative occurrences included nutritional/immune history, such as preoperative weight loss/chronic steroid use (OR = 1.49; 95% CI, 1.03-2.15), as well as physiologic compromise, such as sepsis/inotrope use before surgery (OR = 1.68; 95% CI, 1.10-1.95). Operative factors associated with occurrences included multiple procedures under the same anesthetic (OR = 1.58; 95% CI, 1.21-2.06) and American Society of Anesthesiologists classification category 4/5 versus 1 (OR = 5.74; 95% CI, 2.94-11.24). Specialty complication rates varied from 1.5% for otolaryngology to 9.0% for neurosurgery (p Pediatric has the potential to identify outcomes of children's surgical care that can be targeted for quality improvement efforts.

    In mice of normal weight and with diet-induced obesity, a high-fat, low-carbohydrate ketogenic diet (KD) causes weight loss, reduced circulating glucose and lipids, and dramatic changes in hepatic gene expression. Many of the effects of KD are mediated by fibroblast growth factor 21 (FGF21). We tested the effects of KD feeding on ob/ob mice to determine if metabolic effects would occur in obesity secondarily to leptin deficiency. We evaluated the effect of prolonged KD feeding on weight, energy homeostasis, circulating metabolites, glucose homeostasis, and gene expression. Subsequently, we evaluated the effects of leptin and fasting on FGF21 expression in ob/ob mice. KD feeding of ob/ob mice normalized fasting glycemia and substantially reduced insulin and lipid levels in the absence of weight loss. KD feeding was associated with significant increases in lipid oxidative genes and reduced expression of lipid synthetic genes, including stearoyl-coenzyme A desaturase 1, but no change in expression of inflammatory markers. In chow-fed ob/ob mice, FGF21 mRNA was elevated 10-fold compared with wild-type animals, and no increase from this elevated baseline was seen with KD feeding. Administration of leptin to chow-fed ob/ob mice led to a 24-fold induction of FGF21. Fasting also induced hepatic FGF21 in ob/ob mice. Thus, KD feeding improved ob/ob mouse glucose homeostasis without weight loss or altered caloric intake. These data demonstrate that manipulation of dietary macronutrient composition can lead to marked improvements in metabolic profile of leptin-deficient obese mice in the absence of weight loss.

  15. Ipragliflozin Improves Hepatic Steatosis in Obese Mice and Liver Dysfunction in Type 2 Diabetic Patients Irrespective of Body Weight Reduction.

    Full Text Available Type 2 diabetes mellitus (T2DM is associated with a high incidence of non-alcoholic fatty liver disease (NAFLD related to obesity and insulin resistance. Currently, medical interventions for NAFLD have focused on diet control and exercise to reduce body weight, and there is a requirement for effective pharmacological therapies. Sodium-glucose cotransporter 2 (SGLT2 inhibitors are oral antidiabetic drugs that promote the urinary excretion of glucose by blocking its reabsorption in renal proximal tubules. SGLT2 inhibitors lower blood glucose independent of insulin action and are expected to reduce body weight because of urinary calorie loss. Here we show that an SGLT2 inhibitor ipragliflozin improves hepatic steatosis in high-fat diet-induced and leptin-deficient (ob/ob obese mice irrespective of body weight reduction. In the obese mice, ipragliflozin-induced hyperphagia occurred to increase energy intake, attenuating body weight reduction with increased epididymal fat mass. There is an inverse correlation between weights of liver and epididymal fat in ipragliflozin-treated obese mice, suggesting that ipragliflozin treatment promotes normotopic fat accumulation in the epididymal fat and prevents ectopic fat accumulation in the liver. Despite increased adiposity, ipragliflozin ameliorates obesity-associated inflammation and insulin resistance in epididymal fat. Clinically, ipragliflozin improves liver dysfunction in patients with T2DM irrespective of body weight reduction. These findings provide new insight into the effects of SGLT2 inhibitors on energy homeostasis and fat accumulation and indicate their potential therapeutic efficacy in T2DM-associated hepatic steatosis.

    Full Text Available Abstract Background Household food availability is consistently linked to dietary intake; yet behavioral weight control treatment includes only minimal instruction on how to change the home environment to support dietary goals. This pilot study examined whether it is feasible to change the household food environments of behavioral weight loss participants through the use of a commercially available grocery home delivery service. Methods Overweight participants (N = 28; BMI = 31.7 ± 3.6 kg/m2; 89.3% women, 47.9 ± 9.5 years were randomly assigned to 8-weeks of standard behavioral weight loss (SBT or to SBT plus home food delivery (SBT+Home. SBT+Home participants were instructed to do their household grocery shopping via an online service affiliated with a regional supermarket chain and were reimbursed for delivery charges. Results Compared to SBT, SBT+Home produced significantly greater reductions in the total number of foods in the home (p = .01 and number of foods that were high in fat (p = .002. While the groups did not differ in 8-week weight losses, within SBT+Home there was a trend for the number of home deliveries to be associated with weight loss (p = .08. Participants reported that the home delivery service was easy to use and that it helped decrease impulse purchases and lead to healthier choices; however, few planned to continue using the service after the study. Conclusion Encouraging weight loss participants to use a commercially available online grocery ordering and home delivery service reduces the overall number of food items in the home and decreases access to high-fat food choices. More research is needed to determine whether this is a viable strategy to strengthen stimulus control and improve weight loss outcomes.

    Obesity among Black women continues to exceed that of other women. Most weight loss programs created without reference to specific cultural contexts are less effective for Black than White women. Weight control approaches accessible to Black women and adapted to relevant cultural contexts are important for addressing this problem. This paper reports the final results of SisterTalk, the randomized controlled trial of a cable TV weight control program oriented toward Black women. A five group design included a comparison group and a 2 × 2 factorial comparison of a) interactive vs. passive programming and b) telephone social support vs no telephone support, with 12 weekly initial cable TV programs followed by 4 monthly booster videos. At baseline, 3, 8, and 12 months post randomization, telephone and in person surveys were administered on diet, physical activity, and physical measurements of height and weight were taken to calculate body mass index (BMI). Analysis of variance (ANOVA) was used to examine differences over time, and between treatment and comparison groups. Dose variables reflecting use of the TV/video and written materials were also assessed. At 3 months, BMI, weight, and dietary fat were significantly lower and physical activity significantly higher among women exposed to the Cable TV intervention compared to the wait-list comparison group. Significant dietary fat differences were still observed at 8 and 12 month evaluations, but not BMI or physical activity differences. Main effects were not observed for interactive programming or enhanced social support at any time point. Within the intervention group, higher watching of the TV series and higher reading of educational materials were both (separately) associated with significantly lower dietary fat. Cable TV was an effective delivery channel to assist Black women with weight control, increasing physical activity and decreasing dietary fat during an initial intervention period, but only dietary

    Obesity is a significant cause of functional limitations in older adults; yet, concerns that weight reduction could diminish muscle along with fat mass have impeded progress toward an intervention. Meal-based enhancement of protein intake could protect function and/or lean mass but has not been studied during geriatric obesity reduction. In this 6-month randomized controlled trial, 67 obese (body mass index ≥30kg/m(2)) older (≥60 years) adults with a Short Physical Performance Battery score of 4-10 were randomly assigned to a traditional (Control) weight loss regimen or one with higher protein intake (>30g) at each meal (Protein). All participants were prescribed a hypo-caloric diet, and weighed and provided dietary guidance weekly. Physical function (Short Physical Performance Battery) and lean mass (BOD POD), along with secondary measures, were assessed at 0, 3, and 6 months. At the 6-month endpoint, there was significant (p < .001) weight loss in both the Control (-7.5±6.2kg) and Protein (-8.7±7.4kg) groups. Both groups also improved function but the increase in the Protein (+2.4±1.7 units; p < .001) was greater than in the Control (+0.9±1.7 units; p < .01) group (p = .02). Obese, functionally limited older adults undergoing a 6-month weight loss intervention with a meal-based enhancement of protein quantity and quality lost similar amounts of weight but had greater functional improvements relative to the Control group. If confirmed, this dietary approach could have important implications for improving the functional status of this vulnerable population (ClinicalTrials.gov identifier: NCT01715753). © The Author 2016.

    Weight-based bullying is a prevalent problem among youth with overweight and obesity, but remains neglected in existing policy-level strategies to address youth bullying. Parental support is an influential catalyst motivating political will for policy decisions affecting youth, but has received limited research attention. To assess levels of, and predictors of, parental support for school-based policies and state/federal legal measures to address weight-based bullying in 2014 and 2015. Identical online questionnaires were completed by two independent national samples of parents in 2014 and 2015 (N = 1804). Parental support for all policy actions was high (at least 81%) and significantly increased from 2014 to 2015 for legal measures that would a) require state anti-bullying laws to add protections against weight-based bullying, and b) enact a federal anti-bullying law that includes weight-based bullying. These findings can inform policy discourse about remedies for youth bullying, and suggest that parental support for improved legal protections against weight-based bullying is present, consistent, and strong. © 2016 World Obesity Federation.

    Studies have suggested that food rich in dietary fiber may facilitate body weight loss, lower total and LDL-cholesterol levels, and reduce body fat. This study examined the effects of soy fiber (SF) on body weight, body composition, and blood lipids in overweight and obese participants. Thirty-nine overweight and obese college adults (19-39 years of age) were randomly assigned to consume control biscuits or biscuits supplemented with SF for their breakfast for 12 wk (approximately 100 g/day). There were significant differences in changes on body weight, BMI, and LDL-cholesterol (LDL-C) between the two groups after 12-wk intervention (p weight, BMI, waist circumference, diastolic blood pressure, serum levels of total cholesterol, LDL-C, and glucose, body fat, and trunk fat of participants in SF group were observed significantly after 12 wk. SF had favorable effects on body weight, BMI, and fasting LDL-C levels in overweight and obese adults. These effects may be beneficial in antiobesity and the improvement of hyperlipidemia and hypertension (ClinicalTrials.gov registration number-NCT01802840). © 2013 WILEY-VCH Verlag GmbH & Co.

    Childhood obesity is a major health problem with serious long-term metabolic consequences. CD36 is important for the development of obesity-related complications among adults. We aimed to investigate circulating sCD36 during weight loss in childhood obesity and its associations with insulin resistance, dyslipidemia, hepatic fat accumulation and low-grade inflammation. The impact of a 10-week weight loss camp for obese children (N=113) on plasma sCD36 and further after a 12-month follow-up (N=68) was investigated. Clinical and biochemical data were collected, and sCD36 was measured by an in-house assay. Liver fat was estimated by ultrasonography and insulin resistance by the homeostasis model assessment (HOMA-IR). Along with marked weight loss, sCD36 was reduced by 21% (P=0.0013) following lifestyle intervention, and individual sCD36 reductions were significantly associated with the corresponding decreases in HOMA-IR, triglycerides and total cholesterol. The largest sCD36 decrease occurred among children who reduced HOMA-IR and liver fat. After 12 months of follow-up, sCD36 was increased (P=0.014) and the metabolic improvements were largely lost. Weight-loss-induced sCD36 reduction, coincident with improved insulin resistance, circulating lipids and hepatic fat accumulation, proposes that sCD36 may be an early marker of long-term health risk associated with obesity-related complications.

    Colorectal screening for cancer by colonoscopy is recommended for adults 50 years and older. Scheduling patients for sedated endoscopic procedures involves balancing physician schedules, room availability and equipment, proper patient preparedness, and necessary personnel. Both nonattendance and poor preparations contribute to inefficiency, wasted resources, and increased costs. We noted nonattendance rates ranging from 21% to 29%. As a first step, we examined patient factors associated with nonattendance using a retrospective case control study. Younger patients (attendance rate, concomitantly we discovered cancellation rates increasing. Subsequently, an interdisciplinary and interdepartmental quality improvement program has been ongoing to target a number of system-, nurse-, and patient-specific factors contributing to nonattendance and cancellations due to poor preparations. Rates have improved but require ongoing monitoring and surveillance. We describe the ongoing efforts and challenges aimed at both nonattendance and cancellations.

    The aim of the study was to investigate the outcome of change in body weight associated with use of a structured preventive care process among persons with dementia assessed as at risk of malnutrition or malnourished. The preventive care process is a pedagogical model used in the Senior Alert (SA) quality register, where nutrition is one of the prioritized areas and includes four steps: assessment, analysis of underlying causes, actions performed and outcome. An analysis of data from SA with a pre-post design was performed. The participants were living in ordinary housing or special housing in Sweden. 1912 persons, 65 years and older, registered in both SA and the dementia quality register Svedem were included. A national preventive care program including individualized actions. The Mini Nutritional Assessment-Short Form was used to assess nutritional status at baseline. Body weight was measured during baseline and follow-up (7-106 days after baseline). 74.3% persons were malnourished or at risk of malnutrition. Those at risk of malnutrition or malnourished who were registered in all four steps of the preventive care process, increased in body weight from baseline (Md 60.0 kg) to follow-up (Md 62.0 kg) (p=0.013). In those with incomplete registration no increase in body weight was found. Using all steps in the structured preventive care process seems to improve nutritional status of persons with dementia assessed as at risk of malnutrition or malnourished. This study contributes to the development of evidence-based practice regarding malnutrition and persons with dementia.
