SGLT2 Inhibitor Effects on Inflammation and Heart Disease in Obesity Pilot
ObesityPre-diabetesObesity is associated with increased cardiometabolic disease risk due, in part, to heightened chronic inflammation arising from adipose tissue. There are no current targeted therapies to prevent or reverse the chronic inflammation of obesity, and a better understanding of these inflammatory pathways in humans is key to future therapeutic interventions. This project will determine both the anti-inflammatory potential of the SGLT2 inhibitor empagliflozin, and the contribution of adipose inflammation to surrogate measures of cardiovascular disease in a randomized controlled trial of obese patients.
Differences in Nutrient Use During Exercise Between Children of Varying Body Mass Indices and Fitness...
ObesityChildren who have previously participated in the study "MI Energy" will be invited to participate in "SUPER kids". Investigators want to better understand differences in nutrient use (e.g., fatty acid and carbohydrate) during rest and exercise in children of varying body types and activity levels.
Mechanisms Underlying Individual Variations of Taste and Smell in Obesity
ObesityBackground: Changes to the sense of taste or smell can change eating behavior. This may contribute to obesity. Researchers want to see how taste and smell perceptions that affect food choices may differ between people with obesity and without obesity. Objective: To understand the role that senses of taste and smell play in food intake. Eligibility: Adults ages 18-65 with obesity and without obesity Design: Participants will be screened with a medical history and physical exam. They will have a neurological and sensory exam. They will give blood and urine samples. They will be checked for previous SARS-CoV-2 infection. They will complete questionnaires about their eating habits, alcohol use, and smoking history. Participants will have 2 study visits. Participants will give stool, urine, blood, hair, nasal, and saliva samples. These samples will be used for gene testing. Participants will have their weight, height, and hip and waist circumference measured. They will have an imaging scan that measures body composition. Participants will complete questionnaires about their health, eating habits, and food preferences. Participants will have taste tests and smell tests. They will have sensory tests to assess their response to stimuli. Participants will have a dietary assessment. They will complete a food diary and a diet history questionnaire. Participants will get a meal to eat. Data will be collected about their experience. Participants will complete a sleep diary and wear a watch to measure their activity.
Female Obesity Cohort and Intervention Study Group (MOCART Study Group)
Obesity; EndocrinePregnancy in Diabetic2 moreThis prospective observational trial includes women with high risk pregnancies complicated with hyperglycemia in pregnancy and excessive body weight. The participants are enrolled when pregnant and monitored throughout pregnancy and delivery until the offspring is 6 months old. This research addresses the question which risk factors for non-communicable disorders such as hypertension, obesity, type 2 diabetes for a woman and her offspring can be detected during pregnancy and in early childhood.
The Influence of Physical Activity on the Gut Microbiome of Pre-Diabetic Adults
ObesityOverweight5 moreThe present study is a 100-participant randomized controlled 2-arm parallel trial that employs a metagenomic approach to examine how 8 weeks of supervised moderate-intensity treadmill walking exercise (MWE) for 30-45 min 3 times/week alters the gut microbiome, serum short chain fatty acids, and the cardiometabolic profile, body weight, and body composition of individuals 30-64 years old who have overweight or obesity and have prediabetes.
Susceptibility to Infectious Diseases in Obesity
ObesityType2diabetes2 moreThe role of intestinal microbiota is becoming ever more important in the context of obesity, type II diabetes (T2D), and infectious disorders as represented by the emerging discipline "therapeutic microbiology". The gut microbiota is strictly interconnected with obesity and T2D playing also an important role in immune system regulation. Obesity and diabetes can lead to chronic inflammation, which results in the secretion of pro-inflammatory cytokines like IL-6, IL-1, and TNF-alpha, causing immune system alteration which predisposes patients with obesity and T2D to chronic infections. Therefore, the principal aim of the study is to investigate changes in gut microbiota composition between patients with chronic infections or not, so as to attribute to specific phyla the formation of the infections in these patients.
Exploratory Evaluation of the Effect of Cholestyramine on Serum Levels of POPs in Obese Female Patients...
ObesityAbdominal2 moreEnvironmental endocrine disruptors (EDCs) represent a major problem for human health.Some PEEs can accumulate in the fatty tissue of the human body thanks to their lipophilic nature, and are known as persistent organic pollutants (POPs). To assess the benefit of cholestyramine treatment on POPs blood levels in obese patients of childbearing age undergoing bariatric surgery, in order to reduce their preoperative POPs load more rapidly. Indeed, the investigators hypothesize that cholestyramine is capable, outside of acute exposure accidents, of promoting the elimination and release of POPs in the human population. Given this hypothesis, a treatment administered prior to bariatric surgery could reduce pre-operative plasma levels of POPs and thus, in fine, minimize the concentrations reached post-operatively, which are dependent on the release induced by lipolysis (massive and rapid weight loss) and pre-operative plasma concentrations.
Nutritional Intervention-induced Weight Loss During the Oncological Treatment of Obesity-related...
Breast CancerObesity3 moreObesity could become the first evitable cause of breast cancer in the near future. Due to the relatively slow rate of development in this field, greater efforts must be applied in this area. The HYPOTHESIS of this work is that "a therapy to lose weight in breast cancer women with obesity during the oncological treatment could contribute to slowing carcinogenesis, and to improve the response to the chemotherapy, survival and prevent future recurrences by erasing deleterious epigenetic marks". A group of breast cancer women with obesity (n=90) will be treated to lose weight during the oncologic treatment with a low calorie-ketogenic diet or a group educational intervention program of healthy lifestyle. The reversibility of the obesity-related breast cancer epigenetic signatures (EPIC array and pyrosequencing) and other molecular features (QRTPCR, ELISA assays) in blood leukocytes and plasma and the progression of disease will be compared with an obesity (n=30) and normalweight (n=30) group under conventional anticancer therapy. A matched-group of tumor-free women (n=60) with obesity will be also treated to lose weight with the same nutritional interventions and compared with tumor-free women with normal weight (n=30) in order to evaluate the potential preventive function of weight loss therapies on cancer-related odds. The outcomes of this project will directly benefit overweight and obese patients from healthcare systems, and also to have an economic value supporting pharmaceutical and food industry companies in the design of innovative treatments, useful biomarkers and preventive tools.
A Study to Investigate Why Overweight People Regain Weight After a Losing Weight in a Behavioral...
ObesityThe goal of this clinical trial is to determine the physiological basis for the differences in weight regain among adults (25-59 years old) with obesity following participation in a behavioral weight loss program. Eligible participants will undergo a baseline evaluation after which they will enter an up to 20 week behavioral weight loss program with the goal of losing at least 7 percent of their baseline weight within 37 weeks. Participants who meet the weight loss goal will be asked to remain weight stable for 2 weeks after which they will undergo a clinical examination. They will then be observed for 1 year during which they will undergo 2 additional clinical examinations, one 4 months after completing the weight loss program, and the other 12 months after completing the weight loss program.
