Active clinical trials for "Obesity"

In this preliminary short-term study it is investigated, whether a short olfactory stimulation with D-Limonene leads to an acute improvement of glucose metabolism in patients with obesity.

The goals of the proposed study are 1) to provide scientific basis for the relationship between subjective sleep quality, diurnal eating pattern, gut microbiome, and obesity, 2) to develop and test a pragmatic, cost-effective new tool to advance lifestyle changes using E-health approach, and 3) to compare differences in subjective sleep quality, diurnal eating pattern and gut microbiome at baseline 4) to compare changes induced by the E-health intervention among the three study groups and participants with different work schedules.

Maintenance of protein homeostasis is impaired in skeletal muscle of humans with obesity. A hallmark of this defect is distorted expression of isoforms of the myosin heavy chain (MHC) protein, and this defect is linked to obesity-associated adverse health outcomes. By employing exercise and increase in plasma amino acids as investigational tools the investigators intend to modulate the metabolism of muscle MHC isoforms in order to unravel the biological mechanisms that sustain distorted MHC protein metabolism in muscle of humans with obesity.

FATLAS is a prospective, interventional, non Investigational Medicinal Product (IMP) study aiming to characterize the micro- and macroenvironment of breast cancer according to patient adiposity in different histological and molecular subtypes. The macroscopic profiling of the patient's adiposity will be based on Body Mass Index (BMI), bioimpedance analysis and waist-to-hip ratio. Blood samples will be taken for lipidomic analyses and for hormonal and immuno assays. Microscopic profiling of adiposity and inflammation will be done on fresh frozen (FF) and Formalin-Fixed Paraffin-Embedded (FFPE) samples from the tumour resection specimen and will consist of histological characterization, immuno assays, multiplex immunohistochemistry, DNA sequencing and single nuclei RNA sequencing both in the tumour and in adjacent normal mammary tissue.

The frequency of meals is a very important aspect of nutrition, with profound effects on human health and in life expectancy. Excessive energy consumption is totally associated with a significant increase in the incidence of chronic diseases including diabetes. That is why nutritional therapy is recommended for all people with diabetes mellitus type 1 and 2 as an effective complement to your medical treatment. For overweight or obese type 2 diabetic patients, a low-calorie diet along with healthy eating patterns are recommended for weight loss. Similarly, modest body weight decrease may provide clinical benefits in patients, such as improved blood glucose, blood pressure, lipid profile, and others. Data about the role of nutritional habits and energy density being important precursors of obesity and diabetes are well known. On the other hand, data regarding frequency and timing of meals and how these factors relate to corporal weight are not totally understood.

This is an interventional, open-label, randomized (2:1), standard medical therapy-controlled trial. Subjects in the standard therapy group will be given the opportunity to undergo the active endoscopic treatment after 6 months of follow up (open label extension) if they will not achieve an adequate result on body weight. All patients will be followed until the planned end of the study after 36 months from the ESG procedure. To study the effects of endoscopic gastroplasty on weight, metabolic risk factors, quality of life, satiety, gastrointestinal motility and gut microbiota compared to standard medical treatment control group. Primary endpoint: - Total body weight loss (%) Secondary endpoints: Metabolic risk factors (e.g. lipid profile) and anthropometric measurements (e.g hip and waist circumference) Body composition Quality of life Gastroesophageal reflux disease Non-Alcoholic Fatty Liver Disease (NAFLD) Non- Alcoholic-Steato-Hepatitis (NASH) Satiety Gut microbiota Exploratory endpoints: Gut hormones e.g. glucagon-like peptide 1, PYY and ghrelin Gastrointestinal motility

The main objective of the FLAIR-i study is to study the causal role of inflammation in affecting effort-based decision making in brain and behaviour in overweight and obesity, by comparing the effect of the anti-inflammatory agent colchicine vs. placebo.

The goal of this Randomized clinical trial is to compare effectiveness of of using black seed (Nigella sativa) and cumin seed (Cuminum cyminum) on Body composition profile of obese grade 1. The primary objective of this study is To compare effectiveness of of using black seed (Nigella sativa) and cumin seed (Cuminum cyminum) on Body composition profile of obese grade 1. Subjects will be given a consent form and after subjects read and sign the informed consent, they would be included in study according to eligibility criteria.

The main purpose of this study is to learn about the safety and tolerability of LY3502970 when given to Chinese participants with obesity or overweight with weight-related comorbidities. Blood tests will be performed to investigate how the body processes the study drug and how the study drug affects the body. Each enrolled participant will receive LY3502970, or placebo given orally. For each participant, the study will last about approximately 22- and 30-weeks for both cohort 1 and 2, respectively including screening period.

Impaired endothelial function is observed in disease states related to obesity, such as atherosclerosis, coronary artery disease, and diabetes. Reactive oxygen species (ROS) production and resultant oxidative stress contribute to the development of these obesity-related diseases. The enzyme NADPH-oxidase is a major source of oxidative stress within the vasculature, and has been linked with the Metabolic Syndrome. In the investigator's previously funded studies, the investigators demonstrated for the first time that: 1) in vivo ROS were elevated in skeletal muscle of obese as compared to lean or overweight human subjects, 2) perfusion of the NADPH-oxidase inhibitor apocynin locally into muscle normalized ROS levels and reversed local microvascular endothelial dysfunction in the obese individuals, and 3) aerobic exercise training was effective at attenuating in vivo hydrogen peroxide production and reversing microvascular endothelial dysfunction in the obese individuals. The investigators will investigate in this R15 renewal application the mechanism of exercise training-induced alterations in ROS production and action on endothelial dysfunction in obesity using our newly developed microdialysis methodology of monitoring ROS production, in combination with analysis of muscle biopsy samples obtained before and after our previously tested 8-week intervention of aerobic interval exercise training. The objectives of this study are to determine the impact of in vivo NADPH oxidase activity on endothelial function in obese individuals, and to determine the mechanism of training-induced improvements in endothelial function. The investigator's unique microdialysis methodology will allow monitoring of microvascular/endothelial function and ROS generation, as well as the administration of pharmacological agents directly into muscle. The central hypothesis is that it is upregulation of both mitochondrial ROS and NADPH oxidase-derived ROS that results in endothelial dysfunction in obesity, and that exercise training down-regulates mitochondrial-derived ROS, and NADPH oxidase 4, thereby improving endothelial function. The aims of this proposal are to: 1) determine the contributions of mitochondrial ROS and specific NADPH oxidase isoforms to the NADPH oxidase dependent endothelial dysfunction in skeletal muscle of obese individuals; 2) determine the mechanism of ROS reduction and improved endothelial function resulting from an 8-week aerobic interval training program.
