Filter by:Obesity is an increasing health problem in the United Kingdom (UK) and is predicted to worsen. In the UK and worldwide the three most commonly performed operations are laparoscopic adjustable gastric banding ('BAND surgery'), laparoscopic gastric bypass ('BYPASS') and laparoscopic sleeve gastrectomy ('SLEEVE'). All lead to weight loss, but they are associated with different problems. This study (BYBANDSLEEVE) is a randomised trial with a target recruitment of 1341 patients in twelve hospitals and its aim is to compare the effectiveness, cost effectiveness and acceptability of BAND, BYPASS and SLEEVE surgery.
The study evaluates the effects of two commercially available weight loss programs, the TSFL and the MEDD programs, each compared to a self-directed control diet, on changes in body weight over a 16-week weight loss phase, in apparently healthy overweight and obese men and women.
The purpose of this study is to determine if a lifestyle change program for obese patients who are already receiving continuous positive airway pressure (CPAP) treatment can achieve weight loss and overall improvement of obstructive sleep apnea syndrome (OSAS).
Obesity is one of the greatest public health challenges of the 21st century. Its prevalence has tripled in many countries of the European Region since the 1980s, and the numbers of those affected continue to rise at an alarming rate. In addition to causing various physical disabilities and psychological problems, excess weight drastically increases a person's risk of developing a number of noncommunicable diseases including cardiovascular disease, cancer and diabetes, in association or not to metabolic syndrome. The risk of developing more than one of these diseases (co-morbidity) also increases with increasing body weight. Every year a growing number of patient tend to suffer of more severe obesity and difficulty in losing weight even with a restricted diet and exercise. Garcinia mangostana (Sphaeranthus indicus extract) has known for its antioxidant properties; new evidence point out some promising effects in the prevention of lipogenesis and the promotion of lipolysis . Currently in the scientific literature there is only one paper, by Stern et al., showing the association of Garcinia mangostana assumption in low-calorie diet. This work has demonstrated a significant reduction in weight loss , compared to the placebo group,due to the use of Garcinia mangostana. Aim of the present study is the evaluation of safety and efficacy of weight loss in severe obese patients. Also cardiometabolic parameters and flogosys serum indicators will be evaluated before and after 6 month therapy of low calory diet alone or in association with Garcinia mangostana extract.
This study will test the effectiveness of a mobile application that uses an Application Program Interface (API) to distribute evidence-based weight loss interventions. Half of the participants will receive this API-based application, and the other half of the participants will use a non API-based application.
The patients are randomized into 4 groups : Patients undergoing PENS of dermatome T6 in and a 1200 Kcal diet (Group 1), Patients undergoing PENS T6 and a 2000 Kcal/day, Patients undergoing transcutaneous electrical neurostimulation (TENS) of Dermatomes T11-T12 and following a 1200 Kcal diet and those patients following only a 1200 Kcal diet (Group 4). Weight loss, appetite and ghrelin levels at baseline and after treatment are investigated.
Obesity is a major risk factor for mobility problems in older adults and many older adults use a walking aid to help with their mobility. The use of a walking aid changes normal walking patterns and makes walking harder, leading people to have more functional problems. The purpose of this study is to test the effects of 12 months of a multi-modal balance intervention (MMBI) with supervised weight loss compared to MMBI only on fitness, functional performance, balance, and economy of gait. Participants will be one of 120 participants in the VAMHCS. Participation in this study is voluntary. The research will be conducted at the VAMHCS. The entire study will take approximately 4 years to complete. Subjects' participation in the study will last 24 months.
The investigators propose to 1) assess the feasibility, acceptability and preliminary efficacy of a gender- and culturally-sensitive weight loss intervention in 48 overweight/obese Hispanic males ages 18-64 over 12 weeks; 2) assess participant characteristics and process measures related to the uptake of mobile-health (mHealth) technology in overweight/obese Hispanic males over 12 weeks; and 3) assess pathologic changes in the liver in Hispanic men enrolled in a 12-week weight loss intervention using a non-invasive MRI as a therapeutic response biomarker.
Understanding how foods and nutrients are digested, absorbed and metabolized when weight is stable and during weight loss induced by very low calorie diet procedure using the technologies of genomics, transcriptomics, proteomics, metabolomics and fluxomics ("omics") will enable generation of new hypotheses that could explain the inter-individual differences in weight loss and could lead to optimization and individualization of therapies designed to lose weight.
Bariatric surgery is a powerful tool for producing significant and durable weight loss. Yet, not all patients achieve initial weight loss success and many patients have weight regain as early as 1-2 years post-surgery. Suboptimal weight loss patterns not fully explained by surgical, demographic, and medical factors has led to greater emphasis on patient behaviors evidenced by clinical guidelines that focus on appropriate eating and physical activity. However, research to inform such guidelines typically has relied on imprecise measures or not been specific to bariatric surgery. There is also little understanding of mechanisms by which psychosocial factors influence outcomes. Thus, there is a need to: (a) measure behaviors and psychosocial factors thought to be related to surgical outcomes (particularly those emphasized in guidelines) using innovative strategies to maximize data quality, (b) determine which behaviors and psychosocial factors are related to outcomes, and (c) explore how psychosocial factors influence weight both directly and via influences on behavior. Our research team was the first to employ innovative mobile health (mHealth) technology within an Ecological Momentary Assessment (EMA) framework to measure adherence to recommended behaviors at 6 months post-surgery. The investigators propose to build on this work by using EMA to measure behavioral, psychosocial, and environmental factors over a longer period to understand how they predict success and risk after surgery. An NIH-funded multi-sensor PiLR HEALTH platform will integrate objective sensor data measuring behaviors and the environments in which they are performed with self-report information collected via smartphone in real-time and in patients' natural environment. Participants (N=100) recruited from 2 ASMBS-designated centers of excellence will complete a 10-day EMA protocol pre-surgery and at 3, 6, and 12 months post-surgery to assess recommended behaviors [e.g., meal frequency, PA], psychosocial indicators with the most prior evidence of an association with surgical outcomes (e.g., mood/depression), and key environmental factors (e.g., type/quality of the food environment). Participants will also be weighed at the above time points. Along with describing patterns in behaviors and their relation to weight loss, the investigators will test causal models to understand how complex systems of behavioral, psychosocial, and environmental factors affect weight loss, and to identify optimal targets for intervention. This project has the potential to build a much more sophisticated and valid understanding of who is and is not successful after bariatric surgery and why. This new understanding will directly contribute to improved (i.e., specific, consistent, and validated) guidelines for recommended pre and postoperative behaviors, which could lead to improved surgical outcomes. The enhanced understanding will also inform behavioral, psychosocial, and environmental targets for intervention that are mostly likely to improve surgical outcomes.
