Filter by:A three months, double-blind, randomised, parallel-group study evaluating the efficacy of sitagliptin (Januvia™) versus placebo on beta-cell function in patients with newly detected glucose abnormalities and acute myocardial infarction or unstable angina pectoris. Primary endpoint Improvement in beta-cell function measured by means of the insulinogenic index (ΔI30/ΔG30) obtained from an oral glucose tolerance test (OGTT). Secondary endpoints 1. Improvement of glucose tolerance by means of an OGTT 2. Improvement in endothelial function 3. Improvement in incretin-independent beta-cell function measured as the Acute Insulin Response (ΔAIRG) during an intravenous glucose tolerance test
The purpose of this study is to evaluate if treatment (insulin or diet) of pregnant women with impaired glucose tolerance (75-g OGTT with a fasting P-gluc <7.0 mmol/l and 2 h P-gluc >10.0 and <12.2 mmol/l) close to normoglycemia reduces children´s birth weight and neonatal morbidity. There will be a focus on treatment according to specific goals and separate follow-up regimes for the children and women post partum.
This study targets older adults (ages 60 and over) who are overweight (body mass index 25-40) with impaired fasting glucose (100 - 125). We propose a three-year, randomized controlled clinical trial (n=300) to determine the effect of a one-year physical activity counseling intervention on glucose metabolism and secondary outcomes compared to usual care.

In Finland the prevalence of T2DM is 12-15% among middle-aged people. The prevalence of less marked disturbances in glucose metabolism and MS is 30-40%. Because MS and T2DM are important risk factors for cardiovascular diseases (CVD), the leading cause of death in western countries, all efforts to reverse the epidemic increase in the incidence of MS and T2DM are warranted. The investigators have focused for years on the prevention and non-pharmacological treatment of T2DM and its complications including studies on genetic regulation of glucose and lipid metabolism after dietary modifications. In the investigators' recent projects, the investigators have studied the effects of long-term dietary interventions on gene expression profiles of fat tissue in subjects who are at risk of T2DM. The ultimate goal of these projects has been to identify genes and gene clusters and their biological pathways that respond to dietary modification and modulate glucose and lipid metabolism, and to develop dietary strategies for prevention of T2DM. The main goal of this project is to find nutrition related early biomarkers for progression of MS to T2DM by using modern technologies of systems biology (transcriptomics, metabolomics) of carefully conducted dietary interventions involving subjects with MS. The data will be analysed by using bioinformatics. The investigators reflect these new data to well-known risk factors for T2DM and CVD, e.g., insulin sensitivity, insulin secretion, serum lipids and inflammatory factors among others. In addition to interventions conducted earlier, a new intervention with a whole grain-berry-fish diet and a whole grain diet compared to a control diet with refined foods will be performed. The aim is to increase the investigators' understanding on the synergistic effects of these foods, because the investigators' previous interventions have shown that these individual foods have beneficial effects on glucose and lipid metabolism. On the contrary, diets with refined foods may be harmful in long-term due to its high insulin response, which may through chronic stress lead to both insulin resistance and beta-cell damage. The significance of this project is to increase understanding of the pathophysiology of MS, T2DM and CVD in physiological, cellular and genetic systems, which may lead to more effective and individualised strategies for treatment and prevention, and better identification of high-risk individuals responsive to specific dietary modifications. Increasing knowledge of dietary factors involved in the progression of MS to T2DM and CVD offers new opportunities to individually tailored diets in the management and prevention of these disorders. The results will also be beneficial for the food industry in developing new functional foods. These results and actions may help delay or even stop the epidemic of MS and T2DM and their negative effect on public health currently seen in Finland and worldwide.
The purpose of this study is to determine if increased intake of low-fat milk products and calcium as part of a calorie restricted diet helps achieve a healthier body weight and body composition and decrease blood glucose levels in people with insulin resistance or type 2 diabetes.
The purpose of this study is to compare the effects of exenatide versus metformin on vascular health with chronic (3-month) therapy and during a 2-hour period following a meal in patients with pre-diabetes. It is predicted that exenatide will improve vascular health to a greater degree compared to metformin.
The purpose of the study is to determine the role of beta-cell function and insulin resistance in the development of impaired glucose tolerance (IGT) and type 2 diabetes in children and adolescents who have an increased risk of developing type 2 diabetes due to overweight/obesity or a family history of overweight/obesity, diabetes and/or impaired fasting glucose. It is hypothesized that: 1)Obese adolescents with IGT will be more insulin resistant than obese adolescents with NGT. Insulin resistance will be the best predictor of changes in glucose tolerance status., 2)Beta cell function will be impaired in obese adolescents with IGT compared to obese adolescents with NGT., 3)Obese adolescents with IGT will present with greater intramyocellular, intrahepatic and visceral fat than obese adolescents with NGT. Furthermore, obese adolescents with IGT will have larger adipocytes, while having significantly fewer adipocytes compared to obese adolescents with NGT. Obese adolescents with IGT will also have altered expression of key genes related to insulin resistance., and 4)Abnormalities in endothelial function as manifested by low FMD and PAT are already present in obese adolescents with IGT and are linked to insulin resistance.
Chronic inflammatory activation in fat tissue can be the link between adiposity and an increased risk for atherosclerosis. Aim of the study is to investigate how molecular alterations in fat tissue can be influenced by regular physical exercise training alone or in combination with a medical therapy (Glitazon or Metformin) in obese patients with stable CAD and impaired glucose tolerance.
The aim is to examine whether pharmacological interventions with thiazolidinedione and angiotensin converting enzyme (ACE) inhibitors can reverse pre-clinical vasculopathy in newly diagnosed diabetic and IGT individuals.
This project will compare the amount of bile acids and their kinetics in overweight and obese people with normal glucose metabolism, impaired glucose tolerance and frank type 2 diabetes. We hypothesize that bile acids will behave differently in these groups. We will also explore the effects of Colesevelam HCl, a medicine that lowers LDL cholesterol by binding bile acids, on bile acids in those groups. We hypothesize the drug may have different actions on bile acids in subjects with different degrees of abnormal glucose metabolism.
