Filter by:The primary purpose of the study is to evaluate the efficacy and safety of APHD-012 (distal jejunal-release dextrose [Aphaia technology, AT]) in obese participants.
The purpose of this study is to determine whether the combination of two dietary supplements: MUSCLE 5, which contains protein, creatine and vitamin D and TRIM 7, which contains beet extract, caffeine, coenzyme Q10, alpha lipoic acid, forskolin extract, green coffee bean extract, green tea and vitamin E, plus exercise can induce greater 'high-quality' weight loss than exercise alone in overweight and obese men and women. First, the investigators will examine whether the addition of these two supplements to a mixed exercise regime (e.g., aerobic and resistance training) induces greater improvements in typical training adaptations (aerobic capacity, upper & lower body muscle strength, lean mass, ASM, fat mass, % body fat, and lean mass/fat mass). Secondly, the investigators will assess improvements in pro- and anti-inflammatory factors, insulin sensitivity, and blood lipids. Third, the investigators will determine effects on perceived stress, sleep quality, hair & nail growth, and health-related quality of life. Overweight men and women will be randomized to either exercise alone or exercise plus supplement for 12 weeks. Training will include mixed exercise (aerobic and resistance) three days per week and supplements will be taken on a daily basis. Before and after the 12-week training period the investigators will assess A) Body weight, BMI, DXA outcomes (total lean mass, total body fat, % body fat, ASM, and lean mass/fat mass), waist circumference, VO2max, and upper/lower body maximal strength, B) Circulatory inflammatory factors, antioxidants, blood lipids, and oral glucose tolerance/insulin sensitivity (OGTT), C) Perceived stress, sleep quality, hair & nail growth, and health-related quality of life and D) Overall Health Index. Benefits of the study to participants may include weight loss and improved health (irrespective of weight loss). Benefits of the study to the scientific community include improved understanding of how high-quality protein- and antioxidant-containing supplements, combined with mixed exercise, affect weight loss and overall health in men and women. Thus, the investigators will be comparing men and women to determine if the response to supplementation and exercise is similar or different between the sexes.
The incidence of type 2 diabetes worldwide is growing rapidly, being one of the fastest growing global health emergencies of the 21st century according to the International Diabetes Federation. In MicrobiAr the investigators seek to achieve type 2 diabetes remission through a plant-based diet and lifestyle intervention identifying and characterizing key changes on the gut microbiome during clinical transitions. Specifically, the investigators aim to characterize and follow-up metabolic pathways from gut microbiome and how they evolve as long as health indicators do over the 2 years of this study.
The EXDECHO study is the first randomized study evaluating the effect of four body positions on diaphragmatic excursion in obese patients by ultrasound. The investigators suppose that the course of the right diaphragmatic hemicupola would be increased by an increasingly horizontal position (gradual increase in the diaphragmatic excursion from standing to lying down). If this hypothesis is confirmed, kinesitherapists will have more informed positioning choices to improve the effectiveness of respiratory rehabilitation.
The purpose of this research is to find out if an aggressive intervention to lose weight, will improve symptoms in patients with obesity-related cardiomyopathy, which is also known as the obese phenotype of heart failure with preserved ejection fraction (HFpEF).
The aim of the study is to compare the effect of a low versus moderate versus high energy turnover on energy intake, appetite and food reward, in adolescents with obesity. 18 adolescents with obesity will then complete three experimental sessions in a randomized order: low, high and moderate Energy turnover.
The aim of this project is to study the effect of an intragastric balloon (IGB) on asthma control in obese patients. Obese patients with uncontrolled asthma will be recruited and randomly assigned to two intervention arms : an intragastric balloon combined with diet and exercise versus diet and exercise alone (control group). The primary endpoint will be the proportion of patients with an improvement based on an Asthma Control Questionnaire (ACQ) score ≥ 0.5 at 1 year compared to baseline.
Bariatric surgery (BS) is currently the most effective treatment in severe obesity. However, a considerable percentage of patients undergoing BS fail to lose sufficient weight or regain weight after initial weight loss during long-term follow-up, which may be attributed to personality traits and pathological eating behaviour. Previous positron emission tomography (PET) studies have shown reduced dopamine D2 receptor availability in obese patients and upregulation of this availability following successful BS in the brain's reward system. Dopamine D2 receptor availability in patients with unsuccessful BS has not been investigated to date.
The investigators aim to test the hypothesis that a microbiome-changing dietary intervention improves food decision-making and to determine the underlying microbiotal and metabolic mechanisms. To this end, 90 overweight/obese adults will be enrolled in a randomized controlled trial to test the effects of a pre-biotic dietary intervention (supplementary intake of soluble fibre) or a behavioural lifestyle intervention (weekly educational program) vs. control condititon (supplementary intake of isocaloric starch) over a period of 26 weeks. Before and after the intervention/control period, participants will undergo task-based functional and structural MRI and cognitive testing. The gut microbiota will be assessed using 16S rDNA next-generation sequencing (V3/V4 region) in stool samples. Diet, anthropometry and lifestyle will be monitored with questionnaires and metabolomics will be assayed in peripheral blood and stool (e.g. SCFA). Using a modulation of gut-brain communication through a prebiotic diet and lifestyle intervention, respectively, the investigators will be able to discover microbiota communities that play a key role for eating behaviour. Related mechanistic insights could help to develop novel preventive and therapeutic options to combat unhealthy weight gain in our obesogenic society.
Adipose tissue turnover plays a critical role in body weight maintenance, and obesity is underscored by the dysregulated balance between fat breakdown and synthesis. Although there are clear health-related benefits of physical activity, little is known about how resistance exercise, as opposed to endurance exercise, can reduce the risk of metabolic disorders, particularly in women. The goal of the proposed study is to investigate the effectiveness of resistance training to improve basal and stimulated fat metabolism in postmenopausal women with obesity and pre-diabetes, potentially serving as a viable and practical approach to prevent the onset of type 2 diabetes.
