Filter by:The purpose of this study is to prospectivly analyze the correlation of triglyceride tolerance and glucose tolerance with cardiovascular morbidity and mortality in patients with stable coronary artery disease within 18 months and to determine, whether measurement of triglyceride tolerance can discriminate patients at risk for cardiovascular events.
Lifestyle and genetic factors interact in the development of obesity and the metabolic syndrome. The molecular mechanisms underlying the beneficial dietary modifications are, however, unclear. We aimed to examine the effect of the long-term 30 moderate weight reduction on gene expression in adipose tissue (AT) and to identify genes and gene clusters responsive to treatment and thereby likely contributing to the development of the metabolic syndrome. Thus, randomized controlled and individualized weight reduction and physical exercise intervention was conducted. In the WR group, glucose metabolism improved that was not seen in other groups. Moreover, an inverse correlation between the change in SI and the change in body weight was found (r =-0.44, p=0.026). Down-regulation of gene expression (p<0.01) involving gene ontology groups of extracellular matrix, cell death was seen. Such changes did not occur in the other groups.
We tested the following hypotheses: 1. That a standardized yoga therapy will improve insulin sensitivity (primary outcome), and other features of the metabolic syndrome such as hypertension and dyslipidemia (secondary outcomes), we will perform a 2-hour oral glucose tolerance test, fasting blood tests, and a physical examination before and after randomization of subjects to a 10-week yoga therapy intervention or wait-list control group. 2. That a yoga therapy is feasible in overweight and underactive individuals with the metabolic syndrome, that adherence to a yoga intervention is acceptable, and that yoga therapy is associated with improved quality of life, we will assess the adherence to twice-weekly yoga group sessions (for weeks1-5) and weekly yoga group sessions (for weeks 6-10), frequency of home yoga therapy practice, and self-reported quality of life before and after the intervention in both treatment groups. 3. To elucidate a potential mechanism for the effect of yoga on changes in insulin resistance by evaluating markers of inflammation from adipose tissue (adipocytokines). We hypothesize that these biochemical parameters will show modest improvement with yoga therapy and that changes in these parameters will be associated with improvements in insulin sensitivity.
NAFLD is a spectrum of liver diseases associated with varying degrees of hepatic steatosis, inflammation, and in some cases, fibrosis. NAFLD is a common observation in all demographics, but the prevalence of NAFLD and nonalcoholic steatohepatitis (NASH) is especially high in the morbidly obese population. Leptin is a cytokine that is encoded by the ob gene and primarily secreted by adipose tissue. The production of serum leptin increases with progressive obesity. Because of this observation, there has been significant interest in potential role of leptin in NAFLD. Our hypothesis is that we will find increased hepatic leptin and leptin receptor expression as the degree of hepatic injury worsens in NAFLD.
The purpose of this study is to better understand the link between obesity and diabetes or pre-diabetes.
Randomized controlled single-blinded intervention study in 111 overweight and obese subjects with risk factors of developing type 2 diabetes, with the aim to investigate effects of isoenergetic high cereal fiber as compared with high protein diets over 6 and 18 weeks. Proof of principle study with analysis according to study protocol, investigating whether isoenergetic high cereal fiber and high protein diets with comparable fat contents, if adhered to and after exclusion of known confounders such as changes in body weight, intake of drugs with known effects on insulin sensitivity, or relevant changes in physical activity, indeed affect insulin sensitivity.
The purpose of this study is to determine whether improvement in fat and muscle metabolism after the treatment with Omacor (fish oils) provides insight into the link between obesity, fat and muscle function leading to metabolic syndrome, which is a risk factor for heart disease and diabetes.
Professor Matti Uusitupa, University of Kuopio, Department of Clinical Nutrition (www.uku.fi) Docent Matej Oresic, VTT (www.vtt.fi) Ursula Schwab, PhD, Docent, Marjukka Kolehmainen, PhD, Docent, Leena Pulkkinen, PhD, Docent, David Laaksonen, MD, PhD, MPH, Docent, Kaisa Poutanen, DSc (Tech), Research Professor ABSTRACT The metabolic syndrome (MS) and type 2 diabetes (T2DM) are the most important health problems worldwide. 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.
A number of studies have shown that certain blood-pressure medications such as ACE-inhibitors and angiotensin-II-receptor blockers (ARB) can reduce the incidence of diabetes mellitus type 2. This protocol will evaluate whether inflammatory mechanisms mediate this effect. The investigators therefore will investigate the effect of telmisartan, a potent ARB, on lipid metabolism, glucose metabolism and inflammation in patients with the metabolic syndrome. Specific parameters will be tested before treatment and after 3 months of treatment. Placebo will be compared to 2 different doses of telmisartan per day.
