Filter by:The goal of this prospective, post-market study is to evaluate safety and efficacy of the AEON™ Endostapler when used in laparoscopic Roux-en-Y gastric bypass surgery.
This is a multi-site, randomized, placebo-controlled clinical trial to examine the weight loss efficacy and cardiovascular safety of phentermine 15 mg daily plus lifestyle therapy versus placebo plus lifestyle therapy among 200 adolescents ages ≥10 to <18 years with obesity.
To study the effect of Liraglutide (3.0 mg daily) on 9-month weight loss in low responders 3-months after bariatric surgery.
The purpose of this research is to test the effects of the Dietary and Physical Activity Guidelines for Americans on health and on eating and exercise behaviors.
Obesity is a major risk factor for cardiovascular disease and diabetes as well as all-cause mortality. The prevalence of obesity has continuously increased in most countries and has doubled in over 70 countries since 1980. The World Health Organization (WHO) estimated in 2014 that ~600 million (13%) adults were obese and ~1.9 billion (39%) were overweight worldwide. Notably, United States and China have the highest numbers of obese adults. According to a national survey in China in 2014 conducted among 146,703 Chinese adults aged 20-59, the prevalence of obesity was 13%, central obesity was 25% and overweight was 41%. In Hong Kong, the Behavioural Risk Factor Survey conducted by the Government in 2016 found 39% of adults were classified as overweight or obese, of which 21% were obese. The prevalence of central obesity has also risen steadily since 1999 in America. By 2030 is projected to reach 55.6% in men, 80.0% in women, 47.6% among girls and 38.9% among boys in the United States. Overweight, obesity and central obesity are now already pandemic public health issues causing heavy burden on healthcare system. Nowadays, lifestyle modification interventions still remain as the primary strategy to manage obesity and obesity-related complications, among which exercise is low-cost and effective. Substantial evidences have demonstrated effectiveness of HIIT and MICT in reducing body adiposity and improving body Anthropometry. However, studies have also pointed out "lack of time" is one of the major barriers preventing patients from exercise participation. Therefore, studies have put focus on low-frequency or low-volume exercise in improving health to reduce time commitment and increase exercise adherence. Among substantial evidence, our recent study demonstrated once-a-week HIIT is effectively in improving body composition. The effectiveness of low-frequency exercise in reducing visceral fat has also been explored. However, a recent meta-analysis showed low-frequency exercise is not effective in reducing visceral fat. Notably, the authors pointed out most of studies included in the meta-analysis adopted cycling exercise modality and they suggested walking or running exercise which recruits more body muscles may exert better results. In this study, we propose to adopt walking exercise modality to fill the research gap identified by the meta-analysis. Also, no study has compared the effectiveness of low-frequency HIIT and MICT in reducing visceral fat determined by magnetic resonance imaging (MRI) previously. Study aim: to examine the effectiveness of once-a-week high-intensity interval training (HIIT) versus moderate-intensity continuous training (MICT) in reducing visceral fat in adults with central obesity
The primary purpose of this observational registry is to evaluate the safety of the easyEndoTM Universal Linear Cutting Stapler and reloads from Ezisurg Medical when used to create anastomoses during standard and robot-assisted laparoscopic Roux-en-Y Gastric Bypass (RYGB) surgery. Stapler performance during surgery as well as post-operative pain and the clinical efficacy of the procedures will be determined as secondary objectives.
The purpose of this study is to comprehensively evaluate Salud Escolar (School Health), a program led by the Mexican Ministries of Health and Education. This comprehensive evaluation considers a design, implementation, results, and impact evaluation of Salud Escolar.
This is an unblinded, randomized control trial of obese women to evaluate the impact of the Traxi Panniculus Retractor (TPR) on the cesarean operative time and surgical blood loss when compared to silk tape.
One of the primary risk factors for the development of diabetes is obesity. While even moderate weight loss achieved by dieting can lead to improvements in metabolic health, reduced-calorie diets are notoriously difficult to sustain. Over the past decade, a number of groups have shown that low protein diets are associated with metabolic health in both rodents and humans. In particular, specific building blocks of protein- the branched chain amino acids (BCAAs) leucine, isoleucine, and valine - are associated with insulin resistance and diabetes in humans. Blood levels of the BCAAs decrease in humans fed a low protein diet, and we recently showed that reducing either dietary BCAAs or protein rapidly restored normal body composition and insulin sensitivity to diet-induced obese mice without reducing calorie intake. Current study will test the metabolic role of dietary BCAAs in humans by completing an adequately powered, randomized controlled study. A total of 132 subjects stratified by gender will be randomized to one of three groups: 1) Control; 2) Low Protein; 3) Low BCAA. Subjects in each group will replace two meals a day (and 2/3rds of their baseline dietary protein) with meal replacement beverages based on either complete protein powder or a BCAA-free medical food for two months. Primary outcomes will be weight and fasting blood glucose levels. A number of secondary outcomes will also be assessed and blood, adipose, and fecal samples will be collected for integrated transcriptional and metabolomic pathway analysis to identify and compare the metabolic pathways affected by low protein and low BCAA diets.
Limited/poor weight loss and weight regain are concerns following bariatric surgery, and weight regain may increase the risk for relapse of comorbidities related to obesity. Medications for weight reduction may assist further weight loss, and support weight maintenance, with positive effects on comorbidities. This pilot study will examine the effect of naltrexone/bupropion and lifestyle advice versus lifestyle advice alone for 7 months in patients with a suboptimal weight trajectory (either little weight loss or weight regain) 2 years or later following bariatric surgery.
