Filter by:This is a 3 month single arm pilot and feasibility study designed to examine the impact of an intermittent fasting lifestyle weight loss intervention on pre-specified clinical milestones (change in body weight, adherence to the fasting program, and moderate-to vigorous physical activity, MVPA) in adults with overweight and obesity and breast cancer after they have completed their cancer treatment. The investigators will also evaluate feasibility of recruitment and retention of study participants, safety of the intervention, and obtain feedback from participants to improve the program. Participants will receive a 3 month lifestyle weight loss program focusing on a 4:3 intermittent fasting paradigm (3 modified fast days per week) and support to increase physical activity to 150 minutes per week. Outcome measures will be assessed at the end of the 3 month intervention (primary endpoint) and after a 3 month weight maintenance follow up phase.
We will conduct a Type I hybrid effectiveness-implementation study to test an integrated telehealth intervention among 400 overweight and obese patients with COPD and OSA. We will include eligible participants receiving primary care at one of five Department of Veterans Affairs (VA) medical centers and their community-based outpatient clinics. We will randomize patients in a 1:1 ratio to the multi-component intervention or "enhanced" usual care, stratifying by age (≥65 vs. < 65) and site. Participants randomized to the intervention will receive an integrated, telehealth-delivered intervention composed of a self-directed lifestyle program and supervised pulmonary rehabilitation. At the end of 3 months, we will offer to enter a recommendation for weight management medications on behalf of eligible intervention participants. In the post-core period (months 4-12), participants will continue to have as-needed access to the lifestyle coach. For participants randomized to the "enhanced" usual care group, study staff will prompt the patient's primary care provider to refer them to existing weight loss management and pulmonary rehabilitation programs. Follow-up will occur at virtual visits at 3 and 12 months. Our primary effectiveness outcome at 1-year is quality of life measured by the SF-12 Physical Component Summary Score. Secondary effectiveness outcomes will include other measures of quality of life (including sleep related impairment), sleep disturbance, disease severity (COPD exacerbations and respiratory event index for OSA), depression, social support, weight loss and cardiovascular risk. In addition to assessing effectiveness, we will also conduct a concurrent implementation process evaluation using the RE-AIM framework.
Cardiovascular disease risk factors, including higher BMIs and poor cholesterol profiles, are on the rise and contribute to the United States' growing disease burden. Cottonseed oil (CSO) is found readily in the food supply, and the investigator's previous studies have demonstrated that incorporating CSO into the diet is sufficient to improve fasting cholesterol profile and improve postprandial lipid and/or glycemic responses in both healthy, and at-risk populations. This study aims to compare CSO to a fatty acid composition-matched diet, on changes in fasting and postprandial lipid metabolism and markers of chronic disease risk. The specific aims are: - Examine the impact of CSO vs. PUFA on fasting and postprandial lipids. - Examine the impact of CSO on other markers of chronic disease risk. Participants will be asked to: - Consume provided meal replacement shakes daily for 28-days. - Attend three weekly short visits for fasting blood draws, body measurements, and collect the next week of study materials, - Attend two longer (5.5h) testing visits which include eating a standardized breakfast meal and having blood drawn periodically before and after breakfast. Researchers will compare CSO vs. PUFA and control groups (receiving a mixture of oils) to see if CSO is unique in imparting health benefits when compared with similar matched oil diets.
The purpose of this study is to evaluate the function of the adjustment procedure with the Spatz4 in subjects with a BMI ≥ 27.
The goal of this clinical trial is to investigate the abundance of a natural odour in human cerebrospinal fluid in obese and lean participants after inhalation thereof. Participants will undergo blood sample collection and inhalation of either a natural odour or placebo through an inhaler in addition to a liquor puncture prescribed in standard of care context.
This study aims to evaluate the efficacy of a multi-component lifestyle interventions during pregnancy on promoting appropriate gestational weight gain, preventing GDM, and improving pregnancy, delivery, and neonatal outcomes among overweight or obese pregnant women. The intervention strategies are developed based on the transtheoretical model and mobile health (via WeChat Public Account in smartphone), and will be conducted online and offline. This study will recruit and follow-up 200 overweight or obese singleton pregnant women (pre-pregnancy BMI≥24 kg/m2) during the first trimester of pregnancy from Weifang maternal and Child Health Center, Shandong Province, China. The 200 overweight or obese pregnant women will be randomly allocated at a 1:1 ratio to either the intervention or control group, stratified by the categorical variables of age, BMI and parity. Participants in the control group will be provided usual prenatal care. The lifestyle intervention will last for approximately 6 months (from 10-14 weeks to 32-36 weeks of gestation). Follow-up timepoints included 10-14 weeks of gestation,24-28 weeks of gestation,32-36 weeks of gestation. The interventions are composed of health education related to gestational weight gain and healthy lifestyles, diet modification, active physical activity, regular individual in-person and telephone sessions, diet behavior monitoring, physical activity monitoring, and weight monitoring with Huawei smart watch. The hypothesis is that lifestyle interventions based on the transtheoretical model and mobile health will result in more appropriate gestational weight gain and lower risk of adverse pregnancy outcomes compared with usual care.
This project comprises an initial crossover placebo-controlled neurophysiological study to ascertain the effect of acute ketone ester ingestion on motor cortex plasticity, followed by a second 2-week intervention study aimed to compare the effect of a ketogenic diet versus ketone ester supplementation on motor cortex plasticity, resting brain function and structure, and metabolic and neuroendocrine responses.
To examine the acute changes in cardiometabolic and neurocognitive outcomes in response to exercise combined with ketone ester supplement in overweight/obese adults.
This trial aims to evaluate the impact on cardiovascular risk control in individuals in risk of being affected by hepatic steatosis through the implementation of a screening test (Fatty Liver Index) in Primary Care. Medical teams in a primary care center will be divided into 2 groups, with one group using the screening test in their clinical practice. The number of interventions on cardiovascular risk occurring in patients attended by each group of medical teams will be evaluated and compared.
The purpose of this study is to collect preliminary data on the feasibility, acceptability, and potential effects of a novel, remotely delivered resistance training program.
