Active clinical trials for "Obesity"

A multidisciplinary investigation examining the circadian mechanisms regulating cardiovascular (CV) risk in obesity. Specifically, in a valid circadian protocol, the investigators aim to study resting cardiovascular risk markers and the reactivity of circadian rhythms in these risk markers to standardized stressors in obesity. Furthermore, using an ingenious approach, the investigators propose to explore impairment in pre/post synaptic function in the cardiac left ventricle.

Obesity is a wide reaching problem in the United Kingdom (UK). The most widely used obesity therapies are based around drugs that reduce dietary fat digestion, and thereby reduce uptake of calories from the diet. While such therapies have proved effective, patient compliance is low due to the unwanted gastrointestinal side effects of these drugs. Dietary fibre is generally classified as dietary material of plant origin that is indigestible to humans. Dietary fibre is in fact a wide range of different compounds that have varied effects on the human body. Initial findings from our laboratory suggest that types of fibre from seaweeds (alginates) can greatly reduce the rate that fat is digested in the laboratory. Our studies have identified which types of fibre are the most effective and our aim is to test whether this reduction in fat digestion is the same within the human body. This will be carried out by sampling the digestive fluid from 40 ileostomy patients over a five hour period following a test meal with and without dietary fibres. All study participants will be provided with test foods specially prepared containing the dietary fibres (e.g. in bread). We will collect data from the participants on what they have eaten and how hungry they feel.

This study aims to investigate the efficacy of a novel home-based high-intensity interval training (Home-HIT) intervention in obese individuals, with elevated cardiovascular disease (CVD) risk. It was hypothesised that Home-HIT would 1) have high adherence to the prescribed exercise intensity (compliance), 2) improve markers of CVD risk, and 3) lead to favourable skeletal muscle adaptations.

The main objective of this study is to assess the safety and tolerability of multiple doses of AMG 598 administered alone or in combination with liraglutide in adults with obesity.

The proposed study is a randomized, open, comparative research involving an intervention group and two control groups. The aims of the study are: 1.To compare levels of depression in female adolescents with obesity and a control group of female adolescents with appropriate weight and height. 2. To investigate whether a decrease in weight due to a short range intervention program provided by dietician for female adolescents with obesity will lead to change in the levels of symptoms of depression and cognitive and executive functions in comparison to a control group of adolescent girls with obesity, matched in age that does not receive such an intervention program. 60 Female adolescents with obesity will be recruited to the study and will be randomized to 1 of two groups- 1. intervention group- participants in this group will attend an intervention program consisting of 12 meetings with dietician and will attend two study visits at the clinic- in the beginning of the study and after three months. 2.Control group- Participants in this group will only come to two study visits at the clinic. In the first two visits they will meet with a dietician and will receive nutrition guidance. Another 30 girls with appropriate weight will be recruited to second control group- this group will come to two study visits at the clinic- in the beginning of the study and after three months. In the first visit participants will receive nutrition guidance by the dietician. In the study visits the following procedures will be performed for all study groups: Blood tests, completion of psychological and nutritional questionnaires, completion of computerized tests and measurements of height, weight, fat mass and circumference of hips.

The global research project was organized as a clinical process starting with an evaluation aiming at the determination of a diagnosis pertaining to the degree of satiety signal capacity. It was extended by a phase of metabolic and behavioural characterization to better understand the clinical condition of the patients. The main part of the program was a weight loss intervention that was focused on high satiating foods. Finally, the process was completed by an evaluation allowing to determine the impact of the intervention on the metabolic and behavioural conditions of the patients.

A total of 126 premenopausal women (42 lean, 42 obese with central obesity, 42 obese with peripheral obesity) will be recruited. Anthropometric measurements and body composition using DEXA will be collected. Overnight fasted subjects will be asked to give baseline blood samples before consuming a meal containing 6 mg 57Fe in the form of FeSO4. Subjects will return after 14 days and a blood sample will be collected for measurement of isotopic enrichment into red blood cells, serving as well as a baseline for the OGTT. Subjects will then be asked to ingest a solution of glucose (50g) containing 100 mg of iron in the form of sodium ferrous citrate (SFC), after which blood samples will be collected 2 hours post iron and glucose load. All three blood samples collected at baseline, 2 weeks post labeled iron load, and 2 hours post glucose/iron load will be analyzed for their levels of iron, glycaemia and inflammatory parameters.

Evaluation of a new technique of liver retraction for the exposure of the His angle in gastric bypass Roux-en-Y surgery.

The purpose of this study is to evaluate the efficacy of a distance follow-up on body mass index decrease at 15 months compared to traditional management in obese adolescents.

Molecular hydrogen (H2) effectively tackles obesity-related disorders in animal models yet no studies so far investigated the effectiveness of H2 for improving biomarkers of obesity in humans. In this double blind, placebo-controlled, crossover pilot trial, the investigators will evaluate the effects of H2 intervention on body composition, hormonal status, and mitochondrial function in middle age overweight women, with hydrogen administered orally for 4 weeks.
