Active clinical trials for "Metabolic Syndrome"

Clinical trial about beneficial effects of natural ingredient containing chlorogenic acid and luteolin on liver health and conditions related to liver (such as metabolic syndrome) for general body health.

This pilot study will test acceptability and feasibility of a sleep extension intervention in community dwelling, short sleeping, racially/ethnically diverse middle aged adults with Metabolic Syndrome (METs). Baseline sleep habits will be assessed and used to guide individualized strategies to extend sleep. A 1-group pre-test, post-test study design will test the efficacy of this 18 week study (2 weeks of baseline data collection, 1 week of study intervention planning, 12 weeks of sleep intervention planning, 12 weeks of sleep intervention delivery, final follow up 3 weeks after last day of the 12 week intervention) on sleep duration, MetS factors (waist circumference, blood pressure, fasting glucose, trigycerides, HDL-c), MetS risk behaviors (poor affective well-being, fatigue) and self regulation. Socio-ecological barriers and facilitators to the intervention will be identified using a quantitative and qualitative approach.

The investigators are examining the effects of potato consumption on indices of glycemic control and cardiovascular health in overweight and obese individuals with type two diabetes mellitus (T2D) to provide feasible and effective dietary ways for individuals to enhance their quality of life. The overall objective of this crossover study is to collect data regarding the effects of potato consumption on indices of glycemic control and cardiovascular health among overweight and obese individuals with T2D. The central hypothesis of this crossover study is that the daily consumption of 100 g white potato for 12 weeks will contribute to improvements in glycemic control, reductions in inflammation, and improvements in blood lipids and vascular function in overweight and obese individuals with T2D compared to a macronutrient-matched refined grain (75 g cooked long-grain white rice) for 12 weeks (with a 2 week washout period between interventions). Specific Aim) The assessment of blood glucose control, vascular function, body composition and overall cardiovascular risk after consumption of potatoes (100g/d for 12 weeks) in individuals with T2D compared to a calorie matched refined grain at the initial baseline visit as well as the 6-, and 12-week study visits (for each 12-week intervention period). This aim will assess changed in blood glucose, insulin, HbA1c, HOMA-IR, and HOMA-β as well as the following: blood pressure (BP) markers of endothelial function [flow-mediated dilation (FMD), pulse wave velocity (PWV), and endothelin-1 (ET-1)] markers of inflammation (C-reactive protein) body composition via bioelectrical impedance (BIA), lean mass and fat mass assessment lipid profiles, consisting of total cholesterol (TC), triglycerides (TG), high-density lipoprotein cholesterol (HDL-C), low-density lipoprotein cholesterol (LDL-C) and oxidized LDL (Ox-LDL). Atherogenic risk ratios (TC/HDL-C, LDL-C/HDL-C, HDL-C/LDL-C) will also be assessed anthropometrics [weight, height, waist circumference (WC), hip circumference (HC), waist-to-hip ratio (WC/HC)]

Metabolic syndrome is considered to be a state of prediabetes and is a major risk factor for cardiovascular disease. Dietary interventions involving extra virgin olive oil (EVOO) supplementation and tree nut consumption can improve cardiometabolic health and reverse metabolic syndrome. The goal of this exploratory study is to establish the feasibility of using a novel measure - epigenetic age - to motivate behavior change and improve cardiometabolic health in individuals with metabolic syndrome.

The patient numbers with metabolic syndrome and diabetes have doubled in the last decade. Data that physical exercise ameliorates the metabolic syndrome are convincing, although the mechanisms of the effect in man are not clear. Numerous endocrine or molecular mechanisms modified by physical exercise are known to be hypoxia-sensitive, i.e. by hypoxia-inducible factor-1 (HIF-1) regulation. Thus, relative hypoxia may link physical exercise and modification of endogenous metabolism. Medical communities seem ill equipped to address the primary issues involved. The investigators have experience with normobaric "hypoxia chambers" and will now test a (physical exercise) training program, using state-of-the-art assessments available nowhere else in Germany. The investigators will compare hypoxia chamber, to ambient training, to test the notion that specific exercise conditions could regulate specific molecular pathways involved in the pathogenesis of the metabolic syndrome. Indeed, hypoxia chamber training could be superior to conventional training in terms of reducing cardiovascular risk factors or improving fitness. The investigators will test overall metabolism-related effects with a metabolic chamber. The investigators will test local metabolism with microdialysis during exercise routines, and the investigators will perform fat and muscle biopsies to investigate tissue-related effects. The investigators include experience from a broad-ranging spectrum. The investigators findings might improve understanding mechanisms linking physical exercise and endogenous metabolism. Furthermore, they could influence decision-making regarding non-pharmacological interventions.

Obesity has a greater detrimental impact on the health of African American women than on any other racial or gender group. Nearly 80% of African American women are overweight or obese in the United States. Hypertension and insulin resistance are more prevalent among African American women as compared to men and Caucasians. These conditions put them at increased risk for the development of diabetes mellitus and cardiovascular disease. Recent studies have reported that a substance named Nitric Oxide (NO)may have some beneficial effect on how the body handles blood sugar and blood pressure. Of interest,some studies have shown that African Americans have decreased function of NO in their blood vessels. In this study proposal the investigators will test if increasing NO function with a PDE-5 inhibitor (sildenafil citrate) will improve pre-diabetes and the health of the inner layer of the blood vessels in obese African American women.

A randomized, open, parallel, multi-center trial to evaluate weight loss efficacy of Smart Care Service in obese patients with metabolic syndrome.

The purpose of this study is to examine the acute health effects of concentrated ambient ultrafine (UF) particulate matter (PM) exposure in patients with metabolic syndrome. Without lifestyle changes or medical intervention these patients are at considerable risk for developing diabetes and cardiovascular disease. Subjects (25-70) were exposed to both UF PM and filtered air for 2hr (at least 2 week interval), physiologic endpoints were measure pre-, post-, and 20hr post-exposure. Our hypothesis is that PM exposure in this population will result in changes in vascular and endothelial response as assessed by flow-mediated dilatation of the brachial artery and various heart rate variability and blood endpoints. This study and similar studies of susceptible populations are needed to provide the EPA with information regarding the health risks associated with ambient levels of UF PM.

Metabolic syndrome (MS) is a clustering of risk factors for cardiovascular disease (CVD) such as hypertension, hypertriglyceridemia, low HDL-cholesterol levels, disorders of glucose metabolism, and insulin resistance. A number of associated conditions are included in the MS spectrum such as abdominal obesity, systemic inflammatory activation, endothelial dysfunction, non-alcoholic fatty liver disease, hyperuricemia, polycystic ovarian syndrome, and microalbuminuria. As a consequence, the diagnosis of MS identifies patients who are at increased risk for type 2 diabetes mellitus and CVD. In the last few years, the potential for MS to trigger renal damage and accelerate the progression of pre-existing nephropathy has become a focus of research. Some studies have suggested that MS can influence the development of CKD, although the underlying mechanisms are not well understood. In this study, the investigators hypothesized that modifying a key component of the MS, namely obesity, could attenuate renal damage. The investigators examined the impact of weight loss on creatinine clearance and urinary albumin excretion in non-diabetic obese patients with MS.
