Filter by:At least 15 million Americans are morbidly obese, or more than 100 pounds overweight. Medical treatments including drugs and behavior modification have proven ineffective in producing significant and lasting weight loss in this group. While bariatric surgery is extremely effective for most patients, it also carries risks for both short and long-term complications. There are currently four different types of bariatric surgery available and the risks and benefits of these procedures vary widely and are strongly affected by patient and clinical characteristics. Decision making under these circumstances should reflect informed patient's values and preferences regarding these trade-offs. Instead, the choice of bariatric procedure is more often driven by the beliefs and experiences of the bariatric surgeon that a patient happens to see. Variability in the type of surgery recommended to patients likely results from some combination of surgeons' subjective opinions and personal experiences with regard to the risks and benefits of the treatment options and delegated decision making on the part of patients. The goals of this research proposal are to develop, implement, and evaluate an informed decision support tool for treatment of morbid obesity. This project will be conducted within the context of the Michigan Bariatric Surgery Collaborative (MBSC), which is a statewide clinical registry and quality improvement program that has the participation of virtually every bariatric surgeon and program in the state of Michigan. The MBSC registry now includes externally audited clinical data for more than 80,000 consecutive bariatric surgery patients. MBSC outcome measures include complications occurring within 30 days as well as weight loss, comorbidity resolution, quality of life and satisfaction at 1, 2, and 3 years after bariatric surgery.
The investigators will study the influence of fat cell size/number and adipose function on weight development over very long time periods (years). By comparing fat biopsies obtained at baseline and after >7 years, the investigators will determine the association between adipose morphology/function and changes in weight or development of cardiometabolic complications (e.g. insulin resistance, type 2 diabetes, dyslipidemia and hypertension).
The Avoiding Diabetes After Pregnancy Trial (ADAPT) study was designed to test the effectiveness of interventions that potentially increase the adoption of Diabetes Prevention Program (DPP) elements by women who had a pregnancy with gestational diabetes mellitus (GDM). The study was conducted as an integrated trial with two separate arms: one to facilitate weight reduction and the other to increase diabetes testing. There were two hypotheses: 1. Women in the testing intervention will be more likely to have received a diabetes test within the 6 months post-intervention than women in the control group. 2. Women in the weight reduction intervention will have lost more weight at the 6-month and 9-month follow-up than women in the control group. The primary study aim was to determine the efficacy of a system of interactive technology-based supports to prompt women with a history of gestational diabetes to take steps to prevent diabetes. The secondary aims were focused on women's engagement: - To evaluate the impact of the weight reduction intervention in terms of participant engagement with the interactive technology-based supports. - To evaluate changes in the women's perception of their personal diabetes risk following after exposure to information about diabetes risk following a pregnancy with GDM. - To identify the determinants and motivators of and barriers to diabetes testing in the 6- to 12-week postpartum period and thereafter, using the Health Belief model to guide the study. There was an additional secondary aim involving metformin: - To evaluate the impact of the diabetes risk reduction intervention in terms of women seeking out their physician's advice on metformin treatment and receiving a metformin prescription, if appropriate.
This study will examine whether a higher protein meal replacement diet (consisting of 1 gram of protein per pound lean body mass) is more effective in causing weight loss compared to a standard meal replacement protein diet (consisting of ½ gram of protein per pound of lean body mass). The study will assign approximately 100 subjects (50 each) to the following arms 1) higher meal replacement diet program 2) standard meal replacement diet program. All participants will meet with a registered dietitian to provide nutrition education and behavior modification, including general exercise recommendations. As part of your participation, you must be willing to undergo a measurement of body fat, and blood tests, and be willing to use Herbalife Meal replacements as part of your diet for the duration of the study (one year).
The goal of this study is to determine the effectiveness of a general intervention that includes encouragement of physical activity and healthy living habits of officers and permanent staff in the IDF
