Filter by:While bariatric surgery is established as a safe and effective alternative with well-defined risks for severely obese adults, little has been published on its use in children. There are many unresolved questions concerning the long-term metabolic and psychological consequences of bariatric surgery in adolescents, and the difference with the adult population. The appropriate timing for bariatric surgery in young people, and the predictors of success and safety still need to be determined. The aim of this long-term prospective study is therefore to establish the safety and efficacy profile of surgical procedures and to clarify whether reductions in morbidity and mortality outweigh the risks of serious surgical complications and lifelong nutritional deficiencies.
The general objective of this study is to identify biomarkers of sleep quality, sarcopenia, insulin resistance, oxidative stress and inflammation associated with prefrailty in middle-aged and elderly obese subjects through the integrated study of sleep patterns, functional cardiovascular testing, olfactory function and circulating molecules. Results from the SleSOB study will contribute to identify molecular and functional determinants of prefrailty, to allow early targeted interventions and will have important implications for empowerment of elderly citizens to self-management of preventive measures and healthy lifestyle.
A recent review demonstrated that Non-alcoholic fatty liver disease (NAFLD) affects 10-35% of the adult population worldwide, with the prevalence approaching 85-100% in obese populations. Current standard treatment for liver reduction before surgery is the use of a very low calorie liquid diet (VLCLD). Multiple studies have shown that a 2-4 week diet with a VLCD will reduce liver volume, in preparation for surgery. Omega-3 (Ω-3) polyunsaturated fatty acids (PUFAs) have been suggested as a treatment for NAFLD. The primary aim of this study is to compare Ω-3 PUFAs and a VLCLD and their effect on left lobe live size before bariatric surgery.
The increasing prevalence of obesity noticed in recent decades is a major public health problem of pandemic nature. According to researches, there will be 2.3 billion overweight adults and more than 700 million people suffering from obesity worldwide by the year 2020.Series of epidemiologic studies has revealed a relative link between morbid obesity and metabolic syndrome type 2 diabetes mellitus, hypertension, hyperlipidemia, insulin resistance and shorter life span. Dyslipidemia specially when combined with obesity significantly increase the incidence of atherosclerosis and its complications and also insulin resistance and hence control of diabetic patients. Hyperlipidemia is widely recognized as one of the main co- morbidities in severe obesity and major risk factor for development of atherosclerosis and then heart related diseases.Bariatric surgery has become a prominent treatment modality after the rapidly increasing prevalence of obesity.
1.Objective The investigators aim to determine the effect of brisk walking prescription (> 10000 steps, > five days, per week) on body components and metabolic risk factors among patients with overweight/obesity. The objectives are as follow: 1. The body components changes before/after the brisk walking prescription (> 10000 steps, > five days per week) intervention in overweight/obesity population; 2. The metabolic risk factors changes before/after the brisk walking prescription (<10000 steps or <five days per week) intervention in overweight/obesity population 2.Study design This study is a prospective 4-month follow-up scheme in which patients were treated with the following intervention: > 10000 steps, > five days, per week. For individual follow-up, body components and metabolic risk factors will be tested before and after the study. Every participants will be followed up in community visits every month. 3. Statistical analysis Statistical analysis will be performed using SPSS 16.0 version package (SPSS Inc., Chicago, IL.). Numerical data will be presented as mean ± standard deviation for normal distribution or otherwise median (interquartile range). Two-sided independent t-test is adopted for between-group comparison on end-points with normal distribution, otherwise non-parametric test. Row-Column table will be analyzed through chi-square test. P<0.05 is taken as statistical significant.
One-third of American children are overweight or obese, leading to an increased risk for cardiovascular disease (CVD), early mortality, and other risks throughout their lifespan relative to normal weight children. In our pilot work, we found that 67-83% of parents underestimate a child's long-term risk of developing cardiovascular disease in adulthood and that parents thought their own child's risks were 13-15% lower than those of a typical child in their community, even controlling for family health and demographic characteristics. Parents were 40 times less likely to predict that their child, rather than a typical child in their community, would be overweight or obese in adulthood. These findings suggest that parents suffer from optimism bias, the tendency to overestimate one's chances of experiencing unlikely positive events. Belief that a child is at increased risk for adverse health outcomes in adulthood could be an important motivator for a family to initiate behavior changes and vice versa. The overall goal of this research is to develop provider-based risk communication approaches to motivate parents of obese children to engage in behavior change to protect their children from CVD and other obesity-related co-morbidities later in life. Specifically, the investigators will: 1. Develop risk communication methods that providers can use to better convey accurate information about a child's health behaviors, obesity status, and future health risks to parents. 2. Using an online experiment, we will evaluate the impact of new risk communication methods on parental engagement in behavior change. 3. Pilot test the feasibility, acceptability, and impact of new risk communication approaches in pediatric primary care clinics. This work will give pediatricians novel tools to effectively discuss the long-term consequences of childhood obesity with parents. The findings from this work will inform an interventional trial that will assess the impact of improved risk communication techniques on child behavior change and health outcomes.
The purpose of this study is to examine how the timing of eating changes 24hr profiles of lipids involved in eating for pleasure and how the body makes and uses energy (metabolism).
This study evaluates the nutritional meal replacement and individualized exercise prescription intervention on overweight and obese type 2 diabetes mellitus. Half of participants will receive nutritional meal replacement and individualized exercise prescription on the basis of conventional glucose-lowering treatment, while the other half will only receive conventional glucose-lowering treatment.
We showed, for the first time, that Z-score increase during obesity was dependent on sex, severity of obesity and age but also on the bone site. Although the increase in BMD at bearing areas seems to be logically explained by the assumption that mechanical stresses have an osteogenic effect on bone tissue, BMD can in no way respond to the concomitant increase in BMD at non-load bearing areas such as the radius. These results suggest that changes in certain systemic compounds, induced by obesity, may interfere with bone metabolism. Moreover, the fact that the BMD or Z score is positively and only correlated with muscle mass and not with fat mass confirm that mechanical stresses are not the only factors acting on bone tissue. Our objectives are to determine the relationship between plasma concentration of myokines, adipokines, bone markers and BMD in obese subjects.
Obese patients have a high level of intestinal microflora imbalance, with serious consequences such as loss of digestive function. Potential mediators of intestinal microbiota are prebiotics, supplements considered safe because they are naturally contained in food and human microbiota. Probiotics are living bacteria which are found in the normal gut microbiota. Synbiotics are combinations of both prebiotics and probiotics. Their use has been studied as a new therapeutic approach for the regulation of intestinal microbiota in various situations of disease, including severe obesity. This is a double-blind, placebo-controlled, randomized clinical trial to assess the effect of synbiotic supplementation (fructo-oligosaccharide and probiotic - 12 g / day) on body mass index in participants with obesity class III, with follow up of 90 days.
