Filter by:Dementia (Alzheimer's Disease) is sometimes called "Type 3 Diabetes" because of the strong connection between Type 2 diabetes (a function of insulin resistance) with Dementia. The investigators therefore hypothesize that Reducing Insulin Resistance using Intensive Lifestyle Intervention (Exercise and Weight loss) + Metformin Treatment in Prediabetic & diet-control-only Diabetic overweight and mildly cognitively impaired individuals 55 years or older would lead to better Cognitive Function (compared to standard care) after 2 years. Subjects will be monitored and assessed using a battery of Cognitive and psychological tests and PET scans to demonstrate glucose utilization in the relevant areas of the brain. This 3-year open-label study aims to recruit 360 subjects with 50% (180 subjects) randomized to receiving Intensive lifestyle intervention with Metformin (if diabetic) vs the other 50% who would receive only the usual standard level of care in the primary care setting.
In this research study, investigators will test the effects of an approved medication for diabetes,Liraglutide, to reduce insulin resistance that develops from eating a diet high in saturated fats.
The hypoglycemic effect of Momordica Charantia has been evaluated in clinical trials in patients with type 2 diabetes mellitus. Important reductions in fasting plasma glucose, glycated hemoglobin (A1C), and fructosamine were observed. It is unknown whether this improvement is due to an improvement in insulin sensitivity and insulin secretion. The purpose of this study is to evaluate the effect of the administration of Momordica Charantia on insulin sensitivity and insulin secretion in patients with type 2 diabetes mellitus.
Major surgery results in a stress- induced catabolic response, marked by post-operative insulin resistance, hyperglycemia and loss of body protein, which is associated with increased morbidity, mortality and adverse outcomes. There has been a great deal of research on different approaches to optimize post-operative insulin sensitivity including hormonal and nutritional interventions, minimally invasive surgical techniques and epidural anesthesia. However, the correlation between insulin resistance and body protein loss is not well understood. Metformin is the most widely used insulin sensitizing and blood glucose-lowering drug in treatment of type 2 diabetic patients. This study will: 1) estimate the correlation between insulin resistance and body protein loss in pre-diabetic lung/colorectal resection patients; 2) investigate whether the post-operative metabolic state can be improved by the pre-operative administration of metformin; and assess the impact of metformin on surgical complications and hospital length of stay. The results of this study will provide insight into the relationship between insulin resistance and post-operative adverse events and potentially suggest a novel approach to improve outcomes using Metformin, a drug already in wide clinical use.
In this double-blind, randomized, placebo-controlled study, we aim to investigate the effects of a long-term supplementation on insulin sensitivity, mitochondrial function and substrate metabolism in healthy overweight men and women. In each group, 21 subjects consume 100mg Resveratrol (RSV) and 150mg Epigallocatechin-gallate (EGCG), respectively Placebo capsules, twice daily over a period of 12 weeks. The subjects receive the capsules after the last pre-measurement and continue to take them throughout the post-measurements. Before and after the supplementation period, we perform a hyperinsulinemic-euglycemic clamp with a glucose-tracer infusion to assess hepatic and systemic insulin sensitivity. Simultaneously, substrate oxidation is measured throughout the clamp by indirect calorimetry. Furthermore, we perform a high-fat mixed meal test, in which we collect blood and measure substrate oxidation during fasted and postprandial conditions. During the meal tests, extra plasma is collected at the start (t=-30) and the end (t=240), of which the supernatant is stored in light-protected tubes (EGCG is mixed 1:1 with an EGCG buffer) for analyzing polyphenol concentrations in the blood. In the male subgroup (21 men), we additionally place each 2 microdialysis probes in the subcutaneous adipose tissue and the gastrocnemius in order to assess local lipolysis and blood flow by means of ethanol infusion. Furthermore, a dexa-scan is performed to assess body composition and biopsies are taken under fasted conditions from the subcutaneous adipose tissue and the quadriceps femoralis muscle. These samples are stored at -80C. Part of the adipose tissue samples is collected to measure adipocyte size. Of the skeletal muscle biopsy, one part is directly buffered and used for the oxygraph to measure mitochondrial function. At last, feces samples are collected before and after the intervention in order to assess energy content, microbial composition and short-chain fatty acid content. Based on previous human studies in our and other departments, we hypothesize that after 12 weeks of the combined polyphenol supplementation, insulin sensitivity and mitochondrial function improve. Furthermore, based on results of a short-term study performed by our group, that demonstrated an increase in energy expenditure, a positive effect on the regulation of body composition might be expected.
This study is being done to better understand the relationship between inflammation and insulin resistance in your Adipose (fat) Tissue .
This is a single center, prospective randomized double blind, parallel and placebo controlled study to evaluate oxidative stress and inflammation before and after treatment with linagliptin for 12 weeks. We will also, testing whether Linagliptin is an insulin sensitizer.
Gymnema sylvestre has demonstrated promising effects in the treatment of obesity, dyslipidemia, hypertension, insulin secretion, among others. The above mentioned findings show that Gymnema sylvestre has an excellent potential for the prevention and treatment of metabolic syndrome.
The purpose of this study is to assess the safety, tolerability, and the effect of food on KQ-791. Each participant may receive up to 3 single doses of KQ-791 (at up to 3 different dose levels) and 1 placebo dose over the course of the study. Up to 6 escalating dose levels may be studied, in two distinct groups or cohorts.
Given that glutamate carboxylation or decarboxylation is key to the metabolic role of osteocalcin (at least in mouse models) and that carboxylation is vitamin K dependent, it is critical to isolate the effect of vitamin K manipulation on carboxylation of osteocalcin and its subsequent effect on glucose metabolism in clinical trials. The purpose of this randomized, double-blind, placebo-controlled clinical trial in adults is to determine whether eight weeks of daily supplementation with vitamin K2 (menaquinone-7) can improve markers in blood associated with diabetes risk.
