Filter by:Severe obesity is associated with considerable reduction of wellbeing and life expectancy. People living with severe obesity tend to die 8 to 10 years earlier. Preoperative management of patients living with severe obesity can be challenging and proper weight-loss may help obtain better outcomes and less morbidity. The effectiveness of GLP-1 analogue Liraglutide in preoperative weight-loss was evaluated in the study.
Evaluation of the efficacy of Phaseolus vulgaris L. dry extract on weight modulation.
Quantify the effect of an innovative weight loss management on rhythm control.
Class 4 obesity is defined as a BMI ≥50Kg/m2, representing approximately ≥150 pounds of excess weight. For patients with Class 4 obesity, metabolic and bariatric surgery (MBS) is the only effective treatment. However, MBS is associated with a higher rate of perioperative morbidity and mortality for patients with Class 4 obesity. Additionally, more patients with Class 4 obesity experience suboptimal weight loss. For patients with Class 4 obesity, preoperative weight loss can reduce the technical difficulty of surgical procedures, rendering MBS safer. Preoperative weight loss may also decrease visceral adipose tissue and liver volume as well as reduce weight-related comorbidities. A very low-calorie diet (VLCD), which involves restricting caloric intake to approximately 800 kcal/day, is one strategy to help patients achieve weight loss preoperatively. Although studies show that a VLCD prior to MBS yields weight loss, reduces liver volume and rates of perioperative complications, most preoperative VLCDs are short (2-8 weeks) with variable adherence. To date, no study has systematically assessed the feasibility and acceptability of a standard 12-week VLCD among patients with BMI ≥50 pursuing MBS. No study has evaluated postoperative weight loss among patients who have undergone a preoperative VLCD. This study will be a single arm trial designed to test the feasibility, acceptability, and preliminary efficacy of a 12-week VLCD program prior to sleeve gastrectomy (SG) and associated weight loss up to 1 year following MBS. The investigators will enroll 24 patients aged 18-70, with a BMI≥50Kg/m2, and are approved for SG. Participants will consume up to 5 meal replacement protein shakes and 2 cups of vegetables daily for 12 weeks. Participants will attend weekly in-person office visits with the clinicians at the Hartford Hospital Medical and Surgical Weight Loss Center in Glastonbury, CT to assess weight loss, physical and mental health, feasibility and acceptability of and adherence to the VLCD. The investigators hypothesize that a 12-week VLCD is feasible in this population, defined as ≥70% (18 out of 24 participants) completing the program. The investigators hypothesize that better attendance at the weekly visits and higher adherence to the diet recommendations will provide greater weight loss preoperatively and percent total weight loss at the completion of VLCD, on the day of MBS, and at 3, 6, and 12 months post-surgery. Findings from this study may lead to additional projects that aim to develop and implement an optimal pre-surgery and post-surgery clinical care model for bariatric patients.
Behavioral weight loss programs for obesity can result in weight loss and health benefits. However, behavioral weight loss often stops despite efforts to continue losing weight, this can be called an involuntarily weight loss plateau. This study investigates changes in metabolism and/or the brain that contribute to the occurrence of an involuntary weight loss plateau.
The purpose of this study is to conduct a 6-month pilot randomized trial to determine the feasibility and acceptability of theory-based mobile weight loss interventions for survivors of adolescent and young adult cancer (AYAs). The interventions use a mobile smartphone application, previously developed for individuals at risk for type 2 diabetes and adapted for AYAs, that integrates weight and physical activity from digital devices with simplified dietary monitoring in a behavioral weight loss program.
The purpose of this study is to examine whether the addition of online yoga classes, compared to health and wellness classes, can improve the amount of weight loss produced from an Internet-based weight loss program. All individuals will receive a 12-month, automated Internet-based weight loss program. Following 3 months of of weight loss treatment, individuals will be randomized to also receive yoga classes or health and wellness classes for 9 months. Assessments will occur at baseline, 3, 6, 12, and 18 months and will include measures of weight, eating behaviors, physical activity, and psychosocial factors.
This study aims to develop and validate a prediction model for estimating the probability of inadequate weight loss one year after sleeve gastrectomy.
Clinical studies, with a distinct focus on weight loss, play a crucial role in evaluating the safety and effectiveness of novel treatments. These trials serve as instrumental means to determine whether new medications surpass conventional therapies, providing substantial evidence for their broader adoption. The primary objective is to meticulously scrutinize trial completion rates and voluntary withdrawals within this specific patient group.
The purpose of this pilot trial is to evaluate the feasibility of a lifestyle intervention where participants will all receive online weight loss counseling delivered via a private Facebook group, but be randomized to the Habit app (developed by the investigators) or MyFitnessPal, a commercial calorie tracking app.
