Active clinical trials for "Metabolic Diseases"

In patients with impaired glucose tolerance (IGT), the researchers want to study the relative effects of pioglitazone, simvastatin, or the combination of both on: intima media thickness (IMT) as an easily assessed marker of atherosclerosis heart rate variability (HRV) as a marker of autonomic neuropathy flow-mediated vasodilatation (FMD) of the brachial artery as a marker of endothelial function vascular and metabolic lab parameters

Studies of the human gut microbiome have suggested that treatment or prevention aimed at the obese microbiome could influence the development of obesity-associated metabolic disturbances. The objective of this project is to explore if a dietary intervention in 60 obese women with the probiotic Lactobacillus paracasei ssp paracasei F19 or flax seed fibres targeting the gut microbiome, can reduce insulin resistance, low-grade inflammation or dyslipidaemia, and to explore the interaction between the human genome and the gut microbiome. The study is based on the following hypotheses: Treatment with the probiotic Lactobacillus paracasei ssp paracasei F19 and flax seed fibres will lower the metabolic risk profile in the intervention groups compared with placebo. The effect on the metabolic risk markers can be correlated with changes in the gut microbiota (measured in faeces). After completion of the dietary intervention, the participants are offered a 10-week weight reduction program. Those who participate in the weight-loss program are invited to an optional follow-up visit in connection with the last visit at the clinical dietician, for the purpose of exploring the effect of weight loss on the gut microbiota and obesity-associated metabolic disturbances.

The purpose of this study is to determine whether the intervention for newly diagnosed abnormal glucose tolerance after coronary stenting will improve the long-term clinical outcome.

Healthy male participants are recruited to observe potentially deleterious changes in appetite regulation and metabolic control. Participants will be provided with an energy intake representative of their daily requirements on the first day of one trial and will be provided with an additional 50% energy intake on the first day of another trial. Outcome variables will be assessed during the second day of each trial in response to a fixed mixed macronutrient meal tolerance test.

Cardiometabolic diseases have been associated with high consumption of sweetened beverages. These products are responsible for the largest portion of the total consumption of fructose in the diet and it is suggested that excessive intake of this monosaccharide may contribute to the development of risk factors for these diseases due to differences in metabolism relative to glucose. However, there is a lack of data in the literature demonstrating the deleterious effects of excessive fructose consumption on vasodilation and whether aerobic training may be able to prevent or mitigate these damages in humans. Therefore, the aim of the study will be to verify the effect of 4 weeks of high fructose diet associated with aerobic training on uric acid levels and its influence on markers related to oxidative stress and vasodilatation. Twenty-one sedentary men and women, aged between 19 and 35 years, will be submitted to 4 weeks of intervention. In a randomized way, subjects will be divided into 3 groups: high fructose diet, high glucose diet and high fructose diet and exercise. Blood samples will be taken before, in the middle and after the intervention to verify the concentrations of uric acid, superoxide dismutase enzyme, thiobarbituric acid, nitrite / nitrate, lipid profile, glucose, insulin, C-reactive protein and endothelin-1. In addition, flow-mediated dilatation, insulin resistance index, pancreatic beta cell functional capacity index, oral glucose tolerance test, 24-hour blood pressure, heart rate variability and body composition will be analyzed. The comparisons will be performed through the Generalized Estimates of Equations, adopting the factors group and time. The Bonferroni post-hoc will be used to identify differences. The accepted level of significance will be 5%.

The purpose of this study is to investigate the effect of interrupting prolong sedentary behavior with interval exercise on postprandial metabolism following a high fat glucose tolerance test.

The order in which the different components of a meal are eaten may have impact on the postprandial metabolic responses to carbohydrates, fat and proteins. This study will compare blood lipids and glycemia regulation following lunches of identical composition but varying the order of intake of the different meal components.

The objective of the trial is to assess the effect of single subcutaneous doses of dasiglucagon versus placebo on post-prandial plasma glucose nadir following a Mixed Meal Test in Roux-en-Y Gastric Bypass (RYGB) subjects

Several studies have shown relationship between exercise intensity and improvement cardiometabolic health such as body composition, endothelial function, blood pressure and blood lipids. It has been suggested that high intensity interval training and also strength or resistance training generate positive effects on metabolic risk factors, nevertheless the comparison between both types of training and their combination has not yet provided conclusive evidence. Also, it has been shown that dietary restriction has similar or more positive effects that exercise alone and the effect is greater when it is combined with exercise. For these reasons, it is necessary to clarify which type of training, in combination with a dietary restriction, is more effective to improve cardiometabolic health

Insulin resistance is closely associated with apparition of type 2 diabetes mellitus; it is an independent risk factor and predicts future cardiovascular events. Hyperinsulinemic euglycemic clamp is a validated method to assessment of insulin resistance and It is also the gold standard technique. However, the complexity and length of this technique render it unsuitable for routine clinical use. In this study, the investigators use a new technique to provide precise, objective, fast and automated quantification of insulin resistance with camera SPECT. They compare the results with those of the measurement of hyperinsulinemic euglycemic clamp in population with or without insulin resistance. The proposed study is to validate this new non-invasive imaging technique for evaluation of insulin resistance in patients with or without insulin resistance with a comparison with hyperinsulinemic euglycemic clamp.
