Obesity Clinical Trials

Patients receiving acyclovir as standard of care will be enrolled into this study. The currently recommended dosing strategy at our institution for obese patients is to receive intravenous acyclovir dosed per an adjusted body weight \[IBW + 0.4(TBW-IBW)\]. They will have blood drawn once prior to the first dose of acyclovir and 10 times thereafter, over a total time period of 12 hours. These patients will already be hospitalized for other reasons, and will not be required to make additional trips to the hospital. A total of approximately 4-5 tablespoons of blood will be drawn for this study. Ten obese patients and 10 matched control (non-obese) patients will be enrolled. Read Less

The goal of this randomized clinical trial is to test the efficacy of a fully digital intervention, combining the Lumen problem-solving therapy virtual coach for depression management with the Diabetes Prevention Program video-based program for weight loss, among racial and ethnic minorities with comorbid depression and obesity. The study aims include: * Determine the efficacy of the vCare intervention at 6 months. Primary outcomes are weight and depression symptom checklist 20-item (SCL-20) score. * Identify predictors of treatment success, defined by achieving clinically significant weight loss (5%) and depression outcomes (50% decline or SCL-20\<0.5), at 6 and 12 months. * Characterize participant experiences and perceptions of the vCare intervention. Eligible participants will be randomized to the early-intervention arm who will receive active treatment for 6 months, followed by maintenance for another 6 months, or the later-intervention arm who will be waitlisted for 6 months and then receive active treatment in the second 6 months.

Socioceconomically disadvantaged individuals typically have poor outcomes in behavioral weight loss interventions, but the reasons for this are unknown. This project will characterize the mechanisms through which adverse daily experiences and present bias -- a cognitive adaptation to harsh and unpredictable environments -- account for disparities in weight loss outcomes.

Pilot study enrolling obese post HSCT (hematopoietic stem cell transplantation) patients at the hematology/oncology clinic at the Mattel Children's Hospital, University of California, Los Angeles. Parameters include percent over the 95th percentile (%BMIp95), zBMI, fasting metabolic metrics, addictive eating habits, and motivation for change. Read Less

The study plans to learn more about what happens to the body after bariatric surgery in people 12 to 24 years old. The study aims to understand why people respond differently to bariatric surgery and how to define success beyond weight loss alone. The study also plans to learn more about whether a medication (semaglutide) can help people 12 to 24 years old who, between 1 and 2 years after bariatric surgery, have not lost as much weight as expected.

We will study obese hypertensive subjects in a randomized, crossover study to determine if two weeks sympathetic blockade improves endogenous glucose production. Subjects will be studied on 3 different occasions after two weeks of receiving either placebo, amlodipine (vasodilator arm) or moxonidine (study arm). The order of the studies will be determined using computer-generated randomization. Patients will be blinded as to which treatment they are receiving on each day. An investigator blinded to the treatment assignment will perform the analysis of the data. Read Less

This study is being done to assess the efficacy of a saliva- based biomarker to predict response to semaglutide for the treatment of obesity. Read Less

Once written consent is obtained, the participant will be provided with an accelerometer to be worn for 7 days to assess current physical activity levels. Subjects will be provided with a standardized diet (55/15/30% CHO/PRO/FAT) prior to collection of pre-intervention data of insulin sensitivity. Individuals will then participate in an 8-week electrical stimulation intervention (30min/day, 3x/week) and randomized into placebo/control, NMES, resistance training combined with NMES (RT +NMES), or resistance training (RT) group (n=15 per group), followed by collection of post-intervention data. The control group will receive electrical stimulation up to sensory level, the NMES group will receive stimulation up to tolerable intensity to induce visible muscle contraction, the RT+ NMES will receive stimulation up to tolerable intensity during resistance training, and the RT group will only receive exercise training. Pre-and post-intervention data includes measurements for body composition, resting metabolic rate, VO2max, insulin sensitivity, and comprehensive blood work. Read Less

To assess whether holding incretin-based therapy before endoscopy reduces the likelihood of clinically relevant Residual Gastric Volume (RGV). Primary Outcomes: * Residual gastric volume that precludes adequate endoscopic examination * Residual gastric volume that necessitates premature termination of the endoscopy procedure * Need for endotracheal intubation due to stomach contents. * Occurrence of aspiration events requiring extended observation/monitoring, unplanned therapeutics, and/or hospital admission Secondary Outcomes: * Presence of any solid food * Presence of moderate liquid content * Increased RGV(Residual Gastric Volume) defined as any amount of solid content or \> 0.8 mL/Kg of fluid content (measured from the aspiration/suction canister). * Differences in primary and secondary outcomes between different medications Read Less

This study aims to determine the relationship between lipid kinetics changes and blood immunosuppressive cells by metabolic surgery in two patient cohorts. Read Less

Weight gain is disproportionately high among young adults compared to other age groups and of particular concern in the military, which is comprised largely of young adults, as obesity has emerged as a threat to national security. Despite the critical need to address weight gain in young military personnel who can face discharge for failing to meet weight standards, there is currently no evidence-based programs available to them. This study aims to adapt an evidence-based weight gain prevention intervention for delivery in a young adult, active-duty military population using mobile technology to prevent weight gain over 2 years .

The purpose of this research is to determine how exercise affects fat (adipose) tissue and how changes to adipose tissue that occur during and after exercise might improve health in aging and obesity. Read Less
