Overweight and ObesityBody Weight Changes3 morePhaoeSOL (Microphyt, Baillargues, France) is a microalgae-based nutritional ingredient developed with a patented production process that has New Dietary Ingredient (NDI) status from the FDA (#1120). It is an extract of the microalgae Phaeodactylum tricornutum standardized to 2.0% Fucoxanthin (FX) content by adding a food grade medium-chain triglyceride (MCT)-oil and a tocopherol-rich (Vitamin E) extract (0.5 % w:w). PhaeoSOL is intended for use as a source of the naturally occurring carotenoid, fucoxanthin, in food supplement products for the general population at levels not to exceed 437 mg/person/day for a maximal duration of 30 days of PhaeoSOL (equivalent to 10 mg fucoxanthin/person/day). Prior studies suggest that marine algae and Fucoxanthinol may have anti-obesity, lipid lowering, and glucose management enhancing properties. The purpose of this proof of concept pilot study is to examine whether dietary supplementation of PhaoeSOL enhances the benefits of women participating in an exercise and weight management program.

Pregnancy Exercise Mode Effect on Childhood Obesity
PregnancyOverweight and ObesityThe overall objective of this proposal is to conduct a longitudinal prospective study of overweight/obese (OW/OB) pregnant women and their offspring to determine which prenatal exercise mode will have the greatest impact on maternal and infant cardiometabolic health. This information may lead to clinical practice recommendations that improve childhood health. This randomized controlled trial will recruit 284 OW/OB pregnant women randomized to an exercise intervention (aerobic (AE), resistance (RE), or aerobic+resistance exercise (AERE)) or to no exercise; their infants will be measured at 1, 6, and 12 months of age. This design will test our central hypothesis that AERE and RE training during pregnancy will improve maternal and offspring cardiometabolic outcomes to a greater extent than AE alone. This hypothesis will be tested with two specific aims: Aim 1. Determine the influence of different exercise modes during OW/OB pregnancy on infant cardiometabolic health and growth trajectories. Hypothesis: AE, RE, and AERE by OW/OB pregnant women will improve offspring neuromotor and cardiometabolic measures at 1, 6, and 12 months postpartum (e.g. decreased %body fat, BMI z-score, heart rate [HR], non-HDL, and C-Reactive Protein (CRP); increased insulin sensitivity) compared to infants of OW/OB pregnant women that do not exercise; AERE and RE will have the greatest impact on improving infant measures. Aim 2. Determine the most effective exercise mode in OW/OB pregnancy on improving maternal cardiometabolic health outcomes. Hypothesis: AE, RE, and AERE by OW/OB pregnant women will improve both maternal cardiometabolic health measures (e.g. decreased BMI z-score, non-HDL, % body fat, HR, weight gain) across pregnancy (16-36 weeks' gestation) and overall pregnancy outcomes (e.g. lower incidence of gestational diabetes, pre-eclampsia, hypertension during gestation) compared to OW/OB pregnant women that do not exercise; AERE and RE will have the greatest impact on improving maternal health measures, with the AERE group having the highest compliance. The proposed study will be the first to provide an understanding of the influence of maternal exercise modes on the cardiometabolic health and growth trajectories of offspring who are at increased risk due to maternal OW/OB. This work will have a significant impact on reducing the cycle of OB, potentially providing the earliest and most efficacious intervention to decrease or prevent OB in the next generation.

Metformin for Chemoprevention of Lung Cancer in Overweight or Obese Individuals at High Risk for...
Lung CarcinomaThis phase II trial determines the effect of metformin extended release on the risk for developing lung cancer in overweight/obese patients that are at high-risk for developing lung cancer. Metformin is widely used to treat type II diabetes and has a long history of safety and minimal side effects. At similar dosage, the drug may have potential anti-cancer activity. Metformin use has been associated with improved survival in patients with non-small cell lung carcinoma, a specific type of lung cancer, and it has also been shown to enhance immune mobilization against tumors. This trial aims to see whether metformin extended release as a preventative treatment may lower the chance of developing lung cancer, and whether it may help patients' immune system learn ("reprogram") to lower a certain type of immune cell (called regulatory T cells) that are linked to tumor development.

Pharmacological and Behavioral Treatments After Bariatric Surgery: Maintenance Treatment (Stage...
Loss-of-Control EatingObesity/OverweightThis study will test the effectiveness of naltrexone/bupropion medication as a maintenance therapy for the treatment of loss-of-control eating and weight loss following bariatric surgery. This is a controlled test of whether, amongst responders to acute treatments, naltrexone/bupropion medication results in superior maintenance and longer-term outcomes compared with placebo.

Nutrition, Immunity, and Covid-19 in Obese People
Vitamin D DeficiencyCovid192 moreThe increased risk of transmission of COVID-19 infection causes the incidence of death in health workers to escalate. It requires further research on risk factors and intervention in health worker professionals, especially on immunity factors and nutritional status. Quality of diet and nutrition is very important to support the immune system when infected. Several probiotic strains have been shown to decrease the duration and incidence of diarrhea and respiratory infections, suggesting the Gut-Lung Axis pathway. Some probiotics also improve the balance of diversity in the composition of the gut microbiota and affect body weight in obese people. Probiotics have also been shown to improve vitamin D absorption. A combination of vitamin D and probiotics may be an alternative to reduce gut dysbiosis that will directly or indirectly reduce the risk and severity of viral infections including SARS-CoV-2.

The HARMONY Study: A Intervention to Reduce Cardiometabolic Risk in African American Women

Overweight and ObesityPregnancy Complications3 moreThe purpose of this study is to determine whether an intervention combining motivational interviewing and follow-up with a mobile phone application will help overweight women and their partners adopt healthy lifestyle habits in the preconception period. This study will also evaluate the impact of the intervention on the weight, waist circumference, and body fat of women and their partners. Women and their partners will be followed through pregnancy to explore the effects of the intervention on the adequacy of gestational weight gain, rates of pregnancy complications, delivery mode, and infant birth weight.

Mobile Attention Retraining in Overweight Female Adolescents
ObesityOverweight2 moreBackground: People are constantly exposed to unhealthy foods. Some studies of adults show that training attention away from unhealthy foods might reduce overeating. Researchers want to see what happens in the brain when teens train their attention away from food through a program on a smartphone. Objective: To study the relationship between eating patterns, body weight, and how the brain reacts to different images. Eligibility: Right-handed females ages 12-17 who are overweight (Body Mass Index at or above the 85th percentile for age). Design: Participants will have 6 visits over about 8 months. Visit 1: participants will be screened with: Height, weight, blood pressure, and waist size measurements Medical history Physical exam Urine sample DXA scan. Participants will lie on a table while a very small dose of x-rays passes through the body. Questions about their general health, social and psychological functioning, and eating habits Parents or guardians of minor participants will answer questions about their child s functioning and demographic data.
