Filter by:Type 2 diabetes mellitus (T2DM) is a significant burden worldwide. In addition to lifestyle intervention, heat therapy has been shown to be effective in improving glycemic control. To date, there are no randomized, controlled trials investigating the efficacy of heat therapy in T2DM. Our aim is to investigate whether heat therapy with natural mineral water can improve blood glucose status in T2DM patients. The HEATED study is a two-arm, randomized, controlled study. Patients with T2DM were randomly assigned to Group A (bath in 38 ° C natural thermal mineral water) or Group B (bath in thermoneutral water - 30-32 ° C). Both groups participate in up to five interventions per week, representing 50 to 60 heat therapies over the 12-week study. Each intervention lasts 30 minutes, preceded by a medical examination.
The study investigates the role of mTOR in mediating enhancement of muscle insulin sensitivity following a single bout of exercise. This will be investigated in young healthy male subjects by administering the pharmacological mTOR inhibitor Rapamycin in a crossover blinded experimental setup known to enhance muscle insulin sensitivity following one-legged knee-extensor exercise.
The objective is to determine if how physical fitness, measured using a treadmill maximal oxidative capacity test, is associated with the capacity to metabolize a high-fat meal in pediatrics (ages 8-17 years). Ability to metabolize the meal will be assessed by profiling mitochondrial and extra-mitochondrial fatty acid metabolites. The investigators will test if fatty acid oxidation mediates the relationship between fitness and markers of metabolic health, such as insulin resistance.
Disturbances in the hypothalamus communication pathways with other regions in the brain and the periphery may represent a potential link between metabolic and cognitive health. The current project evaluates whether enhancing synaptic plasticity of this pathway can improve weight management, insulin sensitivity, and cognitive functions. In recent studies, we were able to show that the human brain is sensitive to insulin with favorable effects on peripheral metabolism and cognition. These brain regions encompass the hypothalamus and its connections to the striatum and prefrontal cortex. We want to investigate whether it is possible to enhance neuroplasticity of insulin-responsive brain regions to suppress the weight gain trajectory and improve dopamine-dependent cognitive functions in people with a high risk to develop type 2 diabetes. For this purpose, neuroimaging tools using high-definition transcranial direct current stimulation (HD-tDCS) and magnetic resonance imaging (MRI) will be implemented to assess synaptic plasticity of a neural network essential for metabolic and cognitive health.
this is an observertional study aimed at Study the association between Insulin resistance estimated by HOMA and Angiographic Severity of Coronary Artery Disease in Non Diabetic & Non Obese Patients.
The purpose of this study is to investigate the effect of whole body vibration on insulin resistance in females with polycystic ovarian syndrome
The NOURISH-OK Study will identify how food insecurity contributes to insulin resistance, an important surrogate marker of many co-morbidities in HIV disease, using an integrated framework to identify key leverage points for insulin resistance. Drawing from these pathways, this study will adapt and evaluate a community-driven, science-informed "food as medicine" intervention designed to lower insulin resistance through healthy food access, food utilization skills, and other self-care behaviors. Knowledge gained from this study can benefit those living with HIV through the prevention and more effective management of pre-diabetes, diabetes, obesity, and non-alcoholic fatty liver disease.
This study plans to learn more about differences in heart disease risk after gender-affirming orchiectomy (i.e., testes removal) in older transgender (trans) women compared to younger trans women.
The investigators aim to evaluate whether and to what extent glucose tolerance, beta cell function, insulin clearance, and glucose metabolic fluxes change in response to an acute increase in plasma triglycerides during lipid infusion, independently of free fatty acid (FFA) levels, in nondiabetic subjects.
The overall purpose of the study is to investigate whether three weeks of intermittent fasting (alternate-day fasting, (ADF)) result in a more pronounced "metabolic shift" towards the use of ketone bodies than three weeks of Western diet. The investigators will use state-of-the-art PET/CT tracer techniques and well-established steady state kinetics methods for glucose and fatty acids. The study results will provide new insights into the physiological basis of the potential cardio-protective effects of ketone bodies during ADF and will determine whether ADF can help prevent and treat heart failure. Ketone bodies are produced in the liver as an alternative fuel when blood glucose levels are low, as can be seen with various types of diets or after strenuous exercise. The energy produced by breaking down ketone bodies has been shown to require less oxygen than breaking down glucose and fatty acids. In a previous study, the investigators observed that ketone bodies act as a kind of "super fuel" for the heart and improve the heart's energy utilization. It is still unknown how high ketone levels are needed to see these cardio-protective effects. As patients with insulin resistance and/or heart failure have a lower glucose uptake in cardiac tissue, and as energy production by the breakdown of fatty acids is oxygen-demanding, an elevated level of blood ketones can therefore potentially reduce the morbidity seen in patients with type 2 diabetes and ischemic heart disease. PET/CT is a non-invasive well-established imaging modality suitable for tracking the fate of metabolites, as most substances or metabolites can be labeled by a suitable PET isotope. PET has sufficient spatial and temporal resolution to enable direct quantification of e.g. uptake and oxidation rates and has been successfully used by the investigators' department to assess heart efficiency, oxygen consumption, and fatty acid metabolism. Currently, the investigators are in the process of validating the PET tracer 11C-beta-hydroxybutyrate (11C-3-OHB) as a radio tracer for human studies. The tracer will be able to detect changes in biodistribution and kinetics of ketone bodies during both Western diets and ADF. The subjects must go through two study periods of each 3 weeks in which the intervention is western diet (no restrictions) and intermittent fasting (fasting every other day), respectively. After both study periods, there will be an examination day with PET scans and various laboratory examinations.
