Preoperative Weight Loss for Open Abdominal Wall Reconstruction

Abdominal Wall Hernia

The goal of this randomized controlled trial is to compare preoperative intensive weight management to upfront surgery in obese patients undergoing complex abdominal wall reconstruction. The main question is will abdominal wall specific quality of life (using the HerQLes survey) for the group undergoing upfront surgery be non-inferior compared to the group in the weight management program.

Chronotype-adapted Diet and Weight Loss

Overweight and Obesity

In humans, prolonged alterations in the circadian rhythm have been linked to cognitive impairments, premature ageing, and oncological and metabolic disorders such as diabetes and obesity. Obesity, in particular, is an ever-increasing condition with innumerable deleterious effects on human health. In recent years, studies have shown a relationship between a person's chronotype (morning or evening) and eating habits, as well as the importance of adapting these habits to physiological rhythms. Furthermore, it has been suggested that customising the caloric distribution of meals according to personal circadian rhythms may influence body weight and be one of the strategies to control overweight and obesity. In spite of the strong interest in this topic and the increasing number of observational studies conducted, there is currently a lack of intervention studies evaluating whether a low-calorie diet that takes into account the individual chronotype may be more effective than a standard low-calorie diet in the treatment of overweight and/or obesity.

Choosing Healthy Activities and Lifestyle Management Through Portal Support

Weight LossOverweight and Obesity2 more

The study aims to randomize 250 participants to 1 of 2 arms: a.) an Active Intervention Group (based on the Look AHEAD* ILI) or b.) a Comparison Group (based on the Look AHEAD DSE Comparison group) to test the hypothesis that a multicomponent, multilevel behavioral weight loss intervention (Active Intervention Group) adapted for underserved groups and delivered through Health Information Technology (Health IT) tools via the Electronic Health Record (EHR) patient portal, will result in significantly greater weight loss 12 months after enrollment compared to the Comparison Group. *The Look AHEAD study was a multi-center, randomized clinical trial involving overweight and obese persons with type 2 diabetes, aimed to determine the effects on the cardiovascular outcomes of an intensive lifestyle intervention (ILI) for weight loss, in comparison to the diabetes support and education intervention (DSE).

Effect of Weight Loss on Body Composition and Metabolic Function in Women With Lipedema

LipedemaMetabolism

Lipedema is a disorder characterized by massive, bilateral accumulation of fat below the waist and in the legs. Enlargement of the lower extremities is often accompanied by leg pain and accumulation of fluid. Little is known about the functional changes that lead to fat accumulation and pain in women with lipedema. The goals of this project are to conduct a comprehensive characterization of abdominal and femoral fat tissues in lean and obese women with lipedema and to evaluate the potential effect of diet-induced weight loss as a therapy. Once enrolled in the study, the following tests will be conducted on lean women with lipedema: characterization of body composition (fat tissue distribution), insulin sensitivity (response to insulin) and adipose tissue biology. The following tests will be conducted on obese women with lipedema: characterization of body composition (fat tissue distribution), insulin sensitivity (response to insulin), adipose tissue biology, and immune system function/inflammation. As control, we will have BMI-matched women that are metabolically normal lean (MNL), metabolically normal obese (MNO) and metabolically abnormal obese (MAO) already analyzed in different studies at Washington University (IRB# 201512086). MNL, MAO and MNO subjects underwent the same testing described above for the lipedema. Therefore, we will use the data generated from IRB# 201512086 as comparison groups in the statistical analysis to understand differences and similarities between lipedema and obesity. A second aim of the study is to determine the effect of diet-induced weight loss on body composition, insulin sensitivity, and adipose tissue biology in women with lipedema. The results from this second aim of the study will hopefully provide important insights on the efficacy of diet therapy in managing lipedema.

Expanding Delivery of an Evidence-based Weight-loss Intervention to Enhance Access and Reach Underserved...

Traumatic Brain Injury

The goal of this clinical trial is to extend the accessibility of the Diabetes Prevention Program Group Lifestyle Balance (DPP-GLB) modified for people with TBI (GLB-TBI) to reduce health inequities and reach a broad and diverse sample. To increase the accessibility and reach of the GLB-TBI we will conduct a randomized control trial (RCT) to assess intervention efficacy of telehealth delivery of the GLB-TBI (tGLB-TBI). Results will provide a scalable telehealth weight-loss program that clinicians and community workers across the country can use to help people with TBI lose weight and improve health.

The MULTISITE Study

NAFLDObesity2 more

This study will investigate potential correlations and relationships between obesity and organ-specific complications, including non-alcoholic fatty liver disease (NAFLD), non-alcoholic fatty pancreas disease (NAFPD) and fatty kidney. Furthermore, it will investigate how and if a lifestyle-induced weight-loss intervention decreases liver fat and improve NAFLD. Furthermore, the study will investigate if extracellular vesicles (EVs) can be used as a biomarker for early detection of any of the above-mentioned by comparing obese individuals with NAFLD and metabolic syndrome with both normal weight controls and obese individuals without NAFLD and metabolic syndrome. Lastly, it will investigate if weight changes and the resulting improvement of NAFLD are accompanied by changes in liver-specific extracellular vesicle (EV) phenotypes.

Total Joint Arthroplasty (TJA) Weight Loss Study

OsteoarthritisHip4 more

This is a randomized clinical trial (RCT) to assess the efficacy of bariatric surgery vs medical weight loss vs. the "usual standard of care" to optimize a morbidly obese patient with end-stage osteoarthritis of the hip or knee joint for total joint arthroplasty (TJA). The study population will include patients with hip or knee joint osteoarthritis and BMI (Body Mass Index) > 40 kg/m2 who are evaluated in the joint arthroplasty clinic at Boston Medical Center. The primary objective of the study is to determine if bariatric surgery or medical weight loss is more effective than the usual standard of care in optimizing a morbidly obese patient with osteoarthritis of the hip or knee joint for TJA. This will be determined by comparing the number of patients within each group who are able to lose weight through either bariatric surgery, medical weight loss, or the usual standard of care to achieve a BMI ≤ 40 kg/m2 to eventually undergo TJA. The secondary objectives of this study are to compare total operative time, postoperative complication rates, readmission rates, percentage of total body weight lost, revision rate, and reoperation rate. The ability of patients within each study arm to maintain a BMI ≤ 40 kg/m2 for up to 2 years after undergoing TJA will also be assessed, as well as their level of satisfaction before and after being in the study.

The Impact of Hafnia Alvei on Weight Loss and Glycaemic Control After Bariatric Surgery

ObesityType 2 Diabetes

This study aims to investigate the effects of Hafnia alvei HA4597 TM supplementation on weight loss and glycemic control after bariatric surgery. Patients undergoing Roux-en-Y gastric bypass will receive probiotics or placebo, twice a day, for 60 days, one month after surgery. Outcomes will be measured at baseline, and 1, 3, 6, 9 and 12 months after the surgery.
