Filter by:Coronary flow reserve (CFR, calculated as the ratio of hyperemic over rest myocardial blood flow) is emerging as a powerful quantitative prognostic imaging marker of clinical cardiovascular risk. CFR provides a robust and reproducible clinical measure of the integrated hemodynamic effects of epicardial coronary artery disease (CAD), diffuse atherosclerosis, and microvascular dysfunction on myocardial tissue perfusion. Inflammation is a key mediator of this constellation of abnormalities, affecting the entire coronary vasculature, but no clinical trial to date has shown that directly reducing inflammation lowers cardiovascular event rates. As such, the recently launched Cardiovascular Inflammation Reduction Trial (CIRT) provides a unique opportunity for mechanistic investigation of the impact of anti-inflammatory therapy on changes in CFR as a reflection of coronary vascular dysfunction, which may precede clinical outcomes, particularly in patients at high-risk of events. The investigators are ideally positioned to examine the impact of inflammation on CFR, having extensive experience in both the quantitation of CFR using clinically-integrated dynamic positron emission tomography (PET) and the ability to assess its association with cardiovascular outcomes. The central hypothesis of this ancillary proposal, CIRT-CFR, is that reducing systemic inflammation using low-dose methotrexate (LDM) will, compared to placebo, quantitatively improve myocardial blood flow and coronary flow reserve as measured by PET over one year, in stable CAD patients with type 2 diabetes or metabolic syndrome enrolled in CIRT. In so doing, improvement in coronary vasoreactivity, endothelial function, and tissue perfusion may have beneficial effects on myocardial mechanics, left ventricular deformation and function and, ultimately, symptoms and prognosis.
Type 2 diabetes mellitus, insulin resistance, visceral obesity and disorders of lipid metabolism, especially triglyceride and hypertension are metabolic disorders that play a central role in pathophysiology of metabolic syndrome, and ultimately, the cardiovascular morbidity and mortality associated with atherosclerosis, such as myocardial infarction, cerebral vascular events, vascular dementia, heart failure and end stage renal disease. Recently other complications related with hyperinsulinemia like the prostate benign hypertrophy (BPH). Metformin is the treatment of choice in patients with metabolic syndrome, given its low cost and comparable pharmacological effects to the tiazolinedionas (eg pioglitazone), decreasing hyperinsulinemia, insulin resistance, concentration of free fatty acids and triglycerides, also it produces moderate weight loss, improving the metabolic profile triglcerides atherogenic lipid and carbohydrate and delaying the onset of diabetes mellitus in individuals with impaired fasting glucose. A second option for risk reduction would be the addition of inulin fiber type as it has been demonstrated some metabolic effects on benefices lipid metabolism and carbohydrate. It is expected that combination of metformin with inulin produce a beneficial effect through farmacological synergism and the impact on fisiopatological changes of metabolic syndrome that potentially is considered as an important risk factor for prostate growth.
The present study is designed to examine the effect of changes in body weight and related parameters associated with a commercially-available, low-carbohydrate diet plan. A parameter proposed to be studied here is the impact of fructose restriction and weight loss on serum uric acid concentrations and arterial stiffness.
Presence of metabolic syndrome (MetS) and its relation with insulin resistance, obesity, dyslipidemia, systemic inflammation and cardiovascular disease is of great concern. The study of certain adipokines such as adiponectin has demonstrated an inverse association with insulin resistance, especially in Latin population lower levels of adiponectin have been observed compared to other ethnic groups. It appears to be an important molecule that is involved in limiting the pathogenesis of obesity-linked disorders and may have potential benefits as a marker to evaluate the effect of possible interventions on the MetS components and its complications. Metformin is treatment of choice in patients with MetS, due to its low cost and pharmacological comparable effects with thiazolidinediones (pioglitazone), it decreases hyperinsulinemia, insulin resistance, free fatty acids and triglycerides, it produces as well, a moderate weight loss, improves lipid profile and delays the appearance of diabetes mellitus in subjects with an abnormal fasting glucose. A second choice to lower the risks would be the addition of a fiber like inulin, a prebiotic, since it has demonstrated metabolic benefits on lipid and carbohydrates metabolism by several mechanisms proposed such as induction of lipogenic enzymes by glucose, production of short-chained fatty acids, glucose-dependent insulinotropic peptide (GIP) and glucagon-like peptide-1 (GLP-1), and growth of Bifidobacterium. A good natural source of inulin is the agave. It is expected that the combination of metformin plus agave inulin will produce a beneficial impact through pharmacological synergism and that will produce changes in the pathophysiology of MetS.
The Metabolic Syndrome is a high prevalence disease worldwide. About a quarter of the adult population suffers the disease. Banaba has shown evidence that has on metabolic syndrome, insulin sensitivity and insulin secretion. The investigators hypothesis was that the the administration of resveratrol modifies the metabolic syndrome, insulin sensitivity and insulin secretion.
Metabolic syndrome (Mets) is an assemblage of risk factors which can increase the risk of developing type 2 diabetes mellitus and cardiovascular disease. Green coffee extract (GCE) is derived from unroasted coffee beans and has substantial amounts of polyphenols primarily chlorogenic acids (CGA). It has been shown that GCE and CGA can exert a positive influence over Mets components including blood pressure, blood glucose, inflammation, oxidative stress, insulin resistance and blood lipids. Up to our knowledge no study has been conducted on humans in the field of GCA influences on Mets patients. Therefore, this study is planned to evaluate GCA supplementation effects on anthropometric measurements, glycemic control, blood pressure, lipid profile in patients with metabolic syndrome.
Metformin has been used for alleviating metabolic abnormalities in patients with schizophrenia. Until now, the lowest dose of metformin to treat metabolic abnormalities in clozapine-treated patients is 1000 mg/d. The aim of this study was to determine whether a lower dosage of metformin, such as 500 mg/d, is effective for improving metabolic profiles in clozapine-treated patients with pre-existing metabolic abnormalities. Methods: In this 12-week, randomized, double-blind, placebo-controlled trial, metformin 500 mg/d or 1000 mg/d or a placebo was prescribed to clozapine-treated patients with schizophrenia having pre-existing metabolic abnormalities. The recruited patients underwent physical and laboratory evaluations at week-4, week-8, and week-12.
The purpose of this study is to determine how chronic inflammation influences skeletal muscle protein metabolism and metabolic function in humans. The investigators will evaluate acute responsiveness to a single bout of exercise in men and women who are either lean or overweight/obese. The investigators will explore the relationship between circulating inflammatory markers and anabolic, proteomic, and transcriptional responses to acute exercise. The investigators will measure skeletal muscle protein synthesis in the postabsorptive state and in response to a single bout of exercise.
Increasing rates of highly malignant hepatocellular carcinoma (HCC) and biliary tract cancers (GBTC) observed in Western populations may be related to obesogenic lifestyle factors and their metabolic consequences, such as metabolic syndrome (MetS), inflammation and altered production of bile acids (BA). Such lifestyle behaviours may induce changes in the gut microflora which in turn affect BA profiles, increasing their carcinogenicity. Some elevated BA may be oncogenic in exposed liver, bile ducts and gall bladder. Vertical sleeve gastrectomy may change bile acid composition. The aims of this study are: 1. whether specific presurgical bila acid profiles are predictive of efficacy of vertical sleeve gastrectomy, reflective of liver function and metabolic dysfunction; 2. whether specific presurgical bile acid profiles are predictive of the efficacy of sleeve gastrectomy
Metabolic syndrome (MS) is a complex disease with a cluster of risk factors and clinical features, which includes central or abdominal obesity, atherogenic dyslipidemia, impaired glucose regulation, hyperinsulinemia, high blood pressure, and concomitance of pro-inflammatory cytokine and insulin resistance. Glucomannan (GM) is a water-soluble dietary fiber derived from the root of Amorphophallus konjac that can improve blood sugar, blood fat concentration, and weight management, and has other health benefits.The purposes of this study are going to investigate the effects of KGM noodle (KGN) as stable food to MS and diabetic patients.
