Filter by:The investigators performed a 12-week, randomized, double-blind, placebo-controlled crossover human trial to evaluate the efficacy and safety of chungkookjang on improvement of metabolic syndrome. The investigators measured decrement of body fat parameters, including Body Fat Mass, Percent Body Fat, Fat Free Mass, Weight and BMI(body mass index), and monitored their blood pressure.
Bariatric surgery is the most effective treatment for morbid obesity. Roux-en-Y gastric bypass (RYGB) is a bariatric procedure with known safety and effectiveness. Laparoscopic sleeve gastrectomy (LSG) is a newer procedure gaining popularity. The aim of the study is to compare outcomes of these two surgical methods in terms of weight loss, improvement of common comorbidities of obesity and influence on metabolic and hormonal status.
Several lines of evidence indicate that a significant proportion of cardiovascular disease (CVD) events are attributable to the presence of a cluster of metabolic abnormalities and perturbations, defined as the metabolic syndrome. It has been estimated that approximately 25% of the North American adult population is living with the metabolic syndrome. Recent studies from the investigators group show that overaccumulation of atherogenic triglyceride-rich lipoproteins (TRL) seen in insulin-resistant patients is partly due to increased production rate of intestinally derived apolipoprotein (apo) B-48-containing lipoproteins. This is of interest because substantial evidence exists indicating that elevated levels of intestinal lipoproteins are associated with increased CVD risk. In this regard, there is some evidence that medium-chain triglycerides (MCTs) may beneficially modify lipoprotein metabolism in hypertriglyceridemic patients. However, as emphasized in the body of this grant proposal, the specific impact of MCTs on the intestinal lipoprotein secretion and on expression of genes that regulate intestinal lipid absorption and chylomicron synthesis has not yet been investigated in humans. The general objective of the proposed research is to investigate the mechanisms by which MCTs beneficially modify intestinal lipoprotein metabolism in patients with the metabolic syndrome. The primary hypothesis is that MCT supplementation will decrease plasma levels of intestinal lipoproteins by reducing secretion of these particles.
The project is aimed at investigating the effect of nutrition education on knowledge, attitude and practice (KAP)of subjects who are frequently eating out, and the effect on metabolic parameters.
To examine if 3 months of treatment with a GLP-1 (glucagon-like-peptide-1) analogue can induce weight loss in obese, non-diabetic patients with a diagnosis within the schizophrenic spectrum. The investigators will also examine possible associations between GLP-1 treatment and peripheral metabolic parameters such as change in body fat and HbA1c. Moreover, the GLP-1 analogue treatment will be associated with the effects/changes on cognition and subjective quality of life. Possible cerebral effects (pro-cognitive) of the GLP-1 analogue treatment will associated and correlated with changes in the brain, functional magnetic resonance imaging (fMRI).
Both dietary caloric restriction (CR) and physical exercise (PE) exert beneficial effects, which retard or prevent age-related diseases and prolong life span. Subjects with the metabolic syndrome age prematurely, therefore preventive measures should be initiated early. The present study intends to demonstrate that physical exercise and/or Mediterranean diet, in middle aged volunteers with the metabolic syndrome, preserve adequate adipose tissue functionality and retard skeletal muscle aging (assessed by mitochondrial biogenesis and accumulation of ROS), by activating several pathways, homologous to CR. The investigators plan to study this by using two approaches: 1) A cross- sectional model, in which the expression of the mentioned metabolic mediators, indicators of muscle mitochondrial biogenesis and muscle oxidative damage will be compared between men with different body compositions, fat distribution, muscle strength and exercise capacity (VO2max). Also, in these men the investigators will assess the expression of uncoupling protein 1 (UCP1) in subcutaneous white adipose tissue (as a measure of adaptive thermogenesis), and inflammatory markers (Interleukin 1-6, Interleukin 1ß and CCL2 chemokine (C-C motif ligand 2)) in preperitoneal adipose tissue, plus inflammation and adipogenesis potential of their cultured preadipocytes. Moreover, in vitro studies will evaluate the functional effects of exposure of a cell lyne of human adipocyte cells (LS14)to factors secreted by media conditioned by the patients´ adipose tissue explants. 2) A prospective intervention in overweight/moderately obese middle aged volunteers that will be assigned to a weight-maintenance period (as a control group), and then randomly y assigned to a Mediterranean diet, exercise training or diet plus training. Before and after 3 months of intervention the investigators will obtain muscle tissue samples to study the expression of Peroxisome proliferator activated receptor (PPAR) gamma coactivator 1 alpha (PGC1), uncoupling protein 3 (UCP3), AMP activated protein kinase (AMPK), Sirtuin 1 (SIRT-1), mitochondrial DNA and oxidative damage indicators (8-oxo-7,8-dihydro-2-deoxyguanosine (oxodG), carboxymethyllysine (CML and its receptor (RAGE)). In vitro studies will evaluate the effect of circulating factors from the patients (serum) on LS14 inflammatory and adipogenic potential, at baseline and after 3 months of intervention.
The propose of the study is to test the hypothesis that an eight week program consisting of walking exercise and social cognitive theory based group workshops will increase physical activity adherence six months later in older adults with type 2 diabetes or metabolic syndrome.
This study is conducted to investigate if vitamin E status in healthy individuals and individuals with metabolic syndrome can be improved by dairy fat. The investigators hypothesize that full-fat dairy will substantially increase the bioavailability of alpha-tocopherol, a form of vitamin E. The results of this study will contribute to the application of dairy fat as a simple and effective strategy for improving vitamin E status, which is partly due to poor vitamin E intake. By completing this study, the investigators anticipate developing new dietary recommendations to achieve adequate vitamin E status through the regular consumption of dairy fat paired with foods containing vitamin E.
Little is known regarding the association of individual components of the metabolic syndrome (MBS) and prothrombotic, inflammatory and preclinical cardiac structural and functional markers in women with this syndrome. Less is known about adequate treatment as the pathological mechanism of this syndrome is not well understood. The purpose of this study is two fold; 1. To determine basic differences in biochemical and cardiovascular structural markers in women with and those without MBS and their association with the individual components of MBS. 2. To determine the impact of atorvastatin to lower the risk factors of Metabolic Syndrome. Atorvastatin is one of the most effective drugs approved by the United States Food and Drug Administration (FDA) for the treatment of high cholesterol. It belongs to a class of drugs called statins and its role in primary prevention is still unclear. Thus this population seems to be an ideal group that may benefit from this intervention.
Elevated subconscious nervous system activity is a characteristic of the obese state and contributes importantly to the risk of heart disease and diabetes. This project will compare sympathetic nervous system activity and function in a group of obese persons with differing levels of sugar tolerance (normal, impaired and type 2 diabetic). Inter-relationships with insulin action, blood pressure, heart and kidney function will be determined before and after a 4-month weight loss and 3-month weight loss maintenance program. It is hypothesized that the transition from normal sugar tolerance to impaired sugar tolerance to type 2 diabetes will be accompanied by escalating sympathetic nervous system dysfunction. Furthermore, that weight loss will favorably improve sympathetic function, with greatest benefits occurring in those subjects who are insulin resistant with high blood insulin concentration.
