Filter by:Metabolic syndrome (MetS) is highly prevalent all over the world. MetS is largely under-diagnosed in children and adolescents. Obesity and hypertension are two important requirements for criteria of MetS. With early detection and early intervention of MetS in children and adolescents will enable better care to reduce the heavy burden of health care all over the world. Investigators intend to recruit 150 children and adolescents age 6 to 18 yr with overweight/obesity or prehypertension/hypertension and 50 normal age-matched controls to reach the following research goals: 1) To identify biomarkers as risk factors; 2) To characterize that impact of vascular assessment in preMetS children; and 3) To examine the relationship among biomarkers, vascular assessment parameters, and metabolic phenotypes.
Summary. Theoretical Rationale: The left ventricular myocardial performance results from a complex interplay between linear deformations (longitudinal, circumferential and radial) and twist/ untwist mechanics. These components of myocardial mechanics can be assessed, at rest and during stress conditions, by high resolution echocardiography using the "2D-strain" technology and constitute good indexes of tissue intrinsic contractility / relaxation properties. Type 2 diabetes (T2DM) and metabolic syndrome (MS) are associated with an increased risk for cardiac diseases. While several clinical studies have reported, particularly in T2DM, a diastolic dysfunction (concept of "diabetic cardiomyopathy"), the existence of impaired regional myocardial function, with altered intrinsic contractility properties, remains largely unanswered, especially in the SM. Stress echocardiography is very interesting to reveal myocardial dysfunction, discrete or absent at rest. To the best of our knowledge, no scientific study is, however, today available on the kinetics of linear strains and twist/untwist dynamics in response to stress in T2DM as well as SM. The epicardial adipose tissue is the source of production of important pro-inflammatory cytokines that have the potential, through an exacerbation of oxidative stress, to impair coronary endothelial function, increase fibrosis, but also directly affect cardiomyocyte calcium homeostasis. An increase in epicardial adipose tissue is consensually reported in T2DM and SM and is clearly associated with coronary atherosclerosis. A link between cardiac adiposity and overall cardiac function, particularly diastolic, is now suggested but to our knowledge no study has challenged its association with myocardial dysfunction in T2DM as SM patients. Objectives and Methodology: - To investigate regional myocardial linear deformations and torsion, at rest and in response to a dobutamine stress, in asymptomatic T2DM and SM patients without clinical complications, - to study the links between expected regional myocardial abnormalities and inflammation, hyperglycemia and cardiac adiposity. A control group of healthy individuals matched for sex and age will also be included. All the subjects will benefit from a clinical, anthropometric and biological evaluation. In addition, conventional echocardiography (remodelling and global diastolic and systolic functions) complemented by a functional analysis by tissue Doppler imaging will be performed. Furthermore, 2D cine loops will be recorded in the apical 4, 3 and 2- chamber views for the objective assessment of myocardial longitudinal deformations as well as in the parasternal short axis (base and apex) for the evaluation of the circumferential deformations and basal and apical rotations and left ventricular torsion, at rest and under low dose of dobutamine (110 and 120 bpm).
Metabolic syndrome: aetiology, pathogenesis, diagnosis, clinical management and prognosis
The purpose of this study is to determine whether an increase in lipid bodies in leukocytes will lead to an increase in eicosanoid production. The 2nd purpose is to determine if there is a significant correlation between lipid body formation and enhanced generation of both Lipoxygenase (LO) and COX derived eicosanoids. The 3rd purpose is, if lipid bodies are involved in arachidonic acid (AA) metabolism, then AA present in these lipid rich structure must be released by phospholipases and the free Arachidonic Acid (AA) must have access to the eicosanoid forming enzyme. The fourth objective is to determine the compartmentalisation of cPLA2 and MAP kinases including ERK1, ERK2, p85 and p38 are involved in AA liberation within lipid bodies.
To evaluate the effects of flaxseed supplementation on fasting blood sugar, lipid profile and anthropocentric measurements in subjects with metabolic syndrome, in a randomized, open-labeled, controlled pilot study, 44 subjects with metabolic syndrome will be received 30g/d flaxseed with lifestyle modification or lifestyle modification alone for 12 weeks. Both groups will be advised to follow an energy balanced diet and physical activity recommendations. Parameters related to metabolic syndrome will be measured at the baseline and at the end of the study.
Non-alcoholic fatty liver disease (NAFLD) occurs when excess fat is deposited in the liver. Almost all patients also have obesity and insulin resistance (the inability of the body to effectively use insulin). Obesity and NAFLD are intricately intertwined and are increasing in incidence. While weight loss is the most effective therapy for NAFLD, the investigators' efforts are failing and in the next generation it will become the most common cause of liver failure in Canada. Recently, researchers have focused on the potential use of altering the composition of bacteria in the gut (microbiome) to alter absorption of energy from food, deposition of fat and resistance to insulin. This study will determine if transplantation of bacteria from the stool of a healthy volunteer into an individual with metabolic syndrome and NAFLD (i.e. fecal microbiota transplant/FMT) can alter insulin resistance and reduce the amount of fat deposited in the liver. FMT is being studied to treat several clinical conditions and is now standard of care for the treatment of refractory Clostridium difficile infection. Investigators are proposing a randomized controlled pilot study of FMT in 21 patients to determine the feasibility and to inform us of changes needed for a larger study.
The prevalence of obesity and type 2 diabetes mellitus (DM) in children have been increasing in parallel at an alarming rate. In particular, the increasing prevalence of type 2 DM is attributable to genetic factors, clinical (waist circumference, adiposity and physical condition) and biochemical (insulin secretion and sensitivity, lipids and inflammation) risk, each of which represents an independent risk. As has already studied and published in the investigators' group, the child population of Toluca has greater expression of cardiovascular risk factors than their counterparts in Bogota, Colombia. The metabolic characterization of the young population of Toluca and Bogota with new biomarkers such as homocysteine and leptin is an activity that aims to provide more metabolic data affecting young people. Hypothesis: After six months of follow-up there will be a greater relative risk in Mexican population to have identified another component of metabolic syndrome compared to the young population of Colombia.
The objective of this study is to evaluate the effect of the administration of 25 g of chia per day, for 90 days on the biochemical components of the metabolic syndrome in subjects with this condition
Besides maternal hyperglycemia, a strong link between maternal pregravid weight/maternal triglyceride(Tg) levels and fetal growth/childhood obesity/metabolic syndrome in offspring has been demonstrated in largely Caucasian populations. This study aims to explore the link between maternal hypertriglyceridemia and offspring health in Asians.
The purpose of the study is to develop a culturally adapted intervention (CAI) program to improve weight and physical activity in overweight or obese adult Latinos at high risk for developing type 2 diabetes and/or cardiovascular disease (CVD) and to rigorously evaluate the effectiveness and implementation potential of the CAI program.
