Obesity Clinical Trials

SWIFT-CORE-101 is a single site survey study designed to assess potential participants' eligibility to screen for industry-sponsored clinical trials. A physician will oversee the informed consent process, after which participants will be surveyed on demographics, medical history, comorbidities, and current symptoms. Site staff may collect vital signs, urine drug screens, blood draws, and urine pregnancy tests. A doctor will review medical history with the participant to determine study suitability via clinical interview. The doctor may reach out to the patient's current treating physicians and pharmacies to determine eligibility for clinical trials. Read Less

The goal of this clinical trial is to evaluate the feasibility and acceptability of a 10-wk hybrid Tai Chi (TC) program with in-person classes and online TC videos among 24 physically inactive adults who are seeking metabolic and bariatric surgery (MBS) in a single-arm trial. The aims are: Aim 1: Feasibility: To evaluate whether TC is feasible, defined as a mean attendance rate of ≥70% in-person TC classes attended. Aim 2: Acceptability: To evaluate whether TC is acceptable, defined as a mean rating of ≥4 across 4 acceptability questionnaire items measured on a 5-point Likert scale (e.g., rate "Tai Chi practice is appealing to me" on a scale from 1 \[completely disagree\] to 5 \[completely agree\]). Participants will complete four individual in-person visits where they will complete study assessments and ten weekly group in-person Tai Chi classes where they will practice Tai Chi with up to 5 other study participants. Additionally, they will be asked to practice Tai Chi at home with the aid of instructional online videos and log their practice. Read Less

Interventions that promote water consumption in place of sugar-sweetened beverages have shown promise for preventing childhood obesity in schoolchildren. Yet to date, no studies have examined whether applying this approach in childcare centers could help to prevent childhood obesity at an even earlier stage of development. This cluster-randomized controlled trial will fill gaps by examining how a multilevel childcare-based healthy beverage intervention affects young children's consumption of beverages and obesity.

High body fat at midlife, as evidenced by overweight or obese body mass index (BMI), is increasingly understood as a risk factor for Alzheimer's disease. However, the underlying processes and mechanisms that may underlie this risk remains unknown. With this project, the Investigator proposes to create a new cohort of cognitively normal 120 midlife individuals, age 40-60 years. The investigator and research staff will characterize the participant's overweight or obese status using metabolic tests including, an oral glucose tolerance test, fasting plasma insulin, fasting plasma glucose, and hemoglobin A1c measurements. This testing will generate categories of metabolically abnormal overweight and obese (MAOO), metabolically normal overweight and obese (MNOO), and metabolically normal lean participants (MNLP). Research staff will evaluate differences between these groups on neuroimaging with the newer classification framework of Alzheimer's biomarkers with amyloid (A), tau (T), and neurodegeneration (N), or ATN. Neurodegeneration will be assessed by atrophy on brain MRI as reflected by regional volumes on Freesurfer. Staff will also evaluate MR neuroimaging markers for neuroinflammation using a newer method called diffusion basis spectrum imaging (DBSI), developed at the Mallinckrodt Institute of Radiology at Washington University in St. Louis in collaboration with The Charles F. and Joanne Knight Alzheimer's Disease Research Center (Knight ADRC).

This study will look at whether accounting for the amount of pressure generated by the chest wall and abdomen in a obese patient, using a measurement called transpulmonary pressure, can help shorten the amount of time patients spend on the ventilator. By decreasing the amount of time patients spend on the ventilator, they are less likely to develop complications such as infections, weakness or more procedures. Read Less

The purpose of this study is to conduct a pilot randomized controlled trial of a food is medicine community health worker intervention called the Women's Health Delaware Food Farmacy compared to the usual standard of care among pregnant ChristianaCare patients at risk for adverse clinical outcomes. The pilot study has three specific aims: Aim 1: To assess the feasibility of the Women's Health Delaware Food Farmacy and refine the program as needed Aim 2: To determine the prevalence of and change in social needs Aim 3: To evaluate the effectiveness of the Women's Health Delaware Food Farmacy on maternal and child health, healthcare utilization, and clinical event outcomes as well as patient-reported outcomes compared to the usual standard of care Read Less

The goal of this intervention study is to learn about how weight loss impacts molecular signaling of intermuscular adipose tissue (IMAT) in individuals with obesity. The main question it aims to answer is how inflammatory molecules secreted by IMAT promote muscle insulin resistance and inflammation, and how these same molecules are diminished after weight loss. Following screening visits involving body composition measures, blood testing, strength testing, and a thigh muscle biopsy, participants will go through a 12-week dietary intervention for weight loss. After 12 weeks, this will be followed by the same testing and biopsies that were completed before the intervention. Researchers will then compare outcomes of individuals who lost weight to individuals who did not lose weight. Read Less

The goal of this study is to uncover sleep and circadian mechanisms contributing to adverse metabolic health. The protocol is a 21 day (7 outpatient days, 14 inpatient days) mechanistic randomized-crossover study designed to identify the impact of chronic sleep restriction and circadian timing, independently and in combination on energy metabolism and identify the independent and combined effects on glucose tolerance.

Study Purpose: The combination of caloric restriction and exercise is the most common first-line treatment for obesity-related disorders, yet we know very little about how these two very different treatments work together. A deeper understanding about mechanisms underlying the health benefits of adding exercise to a weight loss program will not only aid efforts to optimize more effective lifestyle interventions, but it can also uncover novel targets for the treatment/prevention of obesity-related diseases. Although a reduction in body fat is the fundamental adaptation to weight loss, we know almost nothing about the effects that adding exercise has on structural and functional changes within fat tissue that may further enhance metabolic health. This is very important because many obesity-related metabolic health complications are tightly linked with abnormalities in abdominal fat tissue. We argue exercise-induced modifications in abdominal fat tissue will reveal persistent health benefits even if some weight is regained Study Summary: 10% Weight Loss Phase - Subject participation in the study will involve a series of metabolic tests before, at midpoint, and after undergoing a 10% weight loss program (with or without exercise training depending on group randomization). During this, subjects will be randomized into one of two different experimental groups: 1. Moderate Intensity Continuous Training (MICT) exercise group 2. No exercise (control) group Follow-up Phase: After completing the metabolic testing post-weight loss, all study-related diet and exercise supervision will end and subjects will be free to make their own choices regarding diet and exercise/physical activity behavior. Subjects will then be asked to complete follow-up testing at 2-, 4- and 6- months post-weight loss. Total involvement in the study for each subject will likely be about 10-13 months (4-7 months during weight loss phase, 6 months during follow-up phase). Read Less

This study will examine a potential relationship between family history of obesity, that is whether people with at least one parent who had obesity in adulthood compared to people with two parents who did not have obesity in adulthood, and the ability of protein intake to curb further intake of food.

Purpose of the Study: This study is to learn more about how exercising at different times of the day (morning versus evening) affects metabolism of glucose in the body, sleep, activity outside of exercise, and other factors. Procedures: * 2 screening visits to make sure you are eligible to be in the study. This will include a fasting blood draw and heart tracing (EKG). * If you are eligible, you will complete both exercise conditions in a random order. All participants in the study will complete the following separated by 3-4 weeks: * Baseline condition of NO exercise * Morning exercise for 3 days in a row * Evening exercise for 3 days in a row * You will be provided with an example diet to follow for the days you are completing the baseline and exercise conditions (three days total for each condition). This diet will be a "traditional" diet with a controlled amount of carbohydrates, protein, and fat per day. The investigators will provide you with examples of meals to eat during this time. * You will be asked questions and complete questionnaires about your health history, sleeping and awakening habits, and sleepiness levels. * You will undergo one x-ray scan to measure your level of body fat. * You will be asked to wear an activity monitor and sleep monitor for 6 days in a row three times during this study. * You will be asked to wear a continuous glucose monitor (CGM) for 6 days in a row three times during this study. * You will be asked to measure your saliva melatonin levels three times in the study. This will be done once per hour for 5 hours (a total of 6 saliva samples). * You will be asked to complete a procedure called a "hyperinsulinemic-euglycemic clamp" where you will have an IV placed and insulin and glucose infused with frequent lab and finger stick blood sugars monitored closely. This will be done 3 times during the study. Read Less
