Active clinical trials for "Overweight"

Dietary fiber intake is protective against overweight and obesity; however, a significant fiber gap exists between consumption and recommended intake values. Soluble fiber beneficially impacts metabolism, and supplementation may be a feasible approach to improve body composition and glycemia in overweight and obese individuals. The investigators will evaluate results of randomized controlled trials (RCTs) of soluble fiber supplementation among overweight and obese adults for outcomes related to weight management (e.g. body mass index [BMI], body weight, body fat percentage, waist circumference) and glucose and insulin homeostasis (e.g. fasting glucose, homeostasis model assessment of insulin resistance [HOMA-IR], fasting insulin) through systematic review and meta-analysis.

The study was aimed at investigating the relationship between skeletal muscle mass and interventricular septum thickness in overweight and obese subjects (BMI≥25)

Non-commercial depersonalized multi-centered registry study on analysis of chronic non-infectious diseases dynamics after SARS-CoV-2 infection in adults.

The study aims to test web-based strategies, in overweight or obese participants at risk or affected by Type 2 Diabetes Mellitus , to promote adherence over time to a healthy lifestyle and nutritional medical therapy (TMN). The study population includes 40 subjects, randomly allocated to web group (therapeutic reinforcement through web-based strategies) or traditional group (traditional educational approach). Anthropometric and clinical parameters will be collected, as well as scores of validated questionnaires will be administered up to 12 months from the enrollment.

Childhood obesity is a major public health issue since it is a risk factor of adulthood obesity, cardiovascular disease, psychological disorders, and other chronic conditions. RéPPOP is a two year personalized pathway for multidisciplinary care for overweight and obese children, close to patients' homes. Short and medium-term assessments of Rhône RéPPOP care for overweight and obese children show encouraging results. Long-term assessment is needed to confirm these results. The present study aims to assess the long-term efficiency of Rhône RéPPOP care for overweight and obese children by comparing BMI Z-scores at the start and the end of RéPPOP care to the current BMI. This data will be collected through a telephonic questionnaire by the scientific manager. The study's secondary objectives are to evaluate patients and their families' lifestyle changes and to improve RéPPOP practices.

The study was aimed to investigating the relationship between circulating level of prealbumin and parathormone (PTH), triglycerides and triiodothyronine (FT3) in overweight and obese subjects (BMI≥25 Kg/m2)

Insulin resistance and a defect in early insulin secretion are risk factors for the development of type 2 diabetes mellitus. A recent longitudinal analysis which tracked the development of diabetes demonstrated that both insulin action and early insulin secretion deteriorate as individuals progress from normal to impaired glucose tolerance and then to diabetes. These results suggest that both inherent (apparent in normal glucose tolerant subjects who progress to diabetes and likely to have a genetic basis) and acquired (evident as individuals progress from NGT to IGT to diabetes and possibly environmental in origin) defects in insulin action and secretion contribute to the pathogenesis of type 2 diabetes. To identify the genetic and environmental determinants of diabetes we are continuing to determine: (1) if there are genes that segregate with metabolic risk factors for diabetes which might therefore be genetic markers for type 2 diabetes and (2) the mechanisms mediating genetic and environmental determinants of insulin resistance and impaired insulin secretion. <TAB> Volunteers for this study will be admitted to the clinical research ward where they will undergo several tests to determine body composition, oral and intravenous glucose tolerance and in vivo insulin action. In addition, in selected subjects, adipose and/or skeletal muscle tissue will be obtained by percutaneous biopsy for in vitro studies of gene expression and insulin action in these tissues. A transformed lymphocyte cell line will be established for each subject as a permanent source of DNA for genetic studies. Genetic markers for type 2 diabetes and insulin resistance will be sought by typing each individual at positional and functional candidate loci in the hopes of finding an association between these loci and obesity, insulin secretion, insulin resistance and/or type 2 diabetes.

Patients over 18 years of age who are admitted to the Intermediate Care Unit of the Clinica del Country and the Clinica la Colina, with symptoms suggestive of severe pneumonia secondary to COVID-19 infection and acute hypoxemic respiratory failure. The primary outcome will be to determine the relationship between body mass index and high-flow cannula therapy success defined as: No need for mechanical ventilation.

The investigators will aim to determine the association of mood disorders (MDO) with preclinical and clinical cardiovascular (CVD) risk factors among children. The investigators will also aim to identify traditional and non traditional predictors of CVD risk among children with MDO.
