Filter by:Pilot study data have demonstrated that peanuts ameliorate the postprandial glucose and insulin response when incorporated into an acute high fat/high glucose meal. However, it is unclear whether acute consumption of peanuts can also influence vascular function. This study will therefore evaluate the effects of acute peanut consumption on vascular function, glycemic control, and plasma lipids. The hypothesis is that that addition of peanuts to a high fat/high glucose meal will reduce the production of triglycerides, glucose, and improve endothelial function as measured by flow-mediated dilation (FMD).
The Dietary Approaches to Stop Hypertension (DASH) trial has been shown to reduce blood pressure and plasma total and LDL-cholesterol (C) compared to a Western diet, but shows no benefit on other blood lipid variables associated with cardiovascular disease (CVD) risk, namely HDL-cholesterol and triglycerides. The overall objective of this study is to determine whether modification of the DASH diet by substituting carbohydrate with fat will result in improvements in multiple biomarkers of CVD risk. Specifically, the investigators will test the hypotheses that modification of the DASH diet by reducing carbohydrate, primarily in the form of simple sugars and glycemic starches, and allowing for a more liberal intake of total and saturated fat, primarily from dairy foods, will: (1) improve lipoprotein markers of CVD risk (reduced total/HDL-C ratio, apolipoprotein B, small LDL particles, and increased HDL-C, apoAI, and large HDL particles); and (2) result in comparable reductions of systolic and diastolic blood pressure to those achieved with the standard DASH diet. The investigators will also assess the effects of the modified DASH diet on markers of insulin resistance and inflammation. Our main hypotheses will be tested by a controlled dietary intervention conducted in 40 healthy men and women who will be randomly allocated to consume, for 3 weeks each, a control Western diet, a standard DASH diet, and a modified low-carbohydrate DASH diet, separated by 2-week washout periods.
Generally, people with low levels of high-density lipoprotein (HDL) in blood are more likely to get heart disease than those who have normal or high levels. Dietary fat, whether the harmful type (saturated) or beneficial type (unsaturated) raises HDL levels. Dietary carbohydrate lowers HDL. The investigators are doing this research study to find out why the amount of HDL in a person's blood is affected by dietary unsaturated fat and carbohydrate. The investigators will trace the ability of the HDL in a person's blood to take up cholesterol, get bigger, and then leave the blood by passing into the liver. The investigators want to know if dietary unsaturated fat improves the ability of HDL to do this compared to dietary carbohydrate.
The purpose of this trial is to assess whether dulaglutide can reduce major cardiovascular events and other serious outcomes in persons with type 2 diabetes, when added to their anti-hyperglycemic regimen.
This pilot study seeks to compare the change in energy expenditure and fitness levels of patients seen in the Children's Hospital Preventive Cardiology program receiving standard of care provider exercise counseling to similar patients receiving Frequency, Intensity, Time, Type (FITT) exercise prescription and counseling combined with BodyMedia supported by an online interactive tool. The investigators primary hypothesis is that this interactive technology coupled with support from a exercise specialist will increase the energy expenditure of the investigators patients over standard of care provider counseling. The investigators Secondary hypotheses include greater improvement in measured physical fitness Peak oxygen consumption (VO2max), oxygen consumption (VO2) at anaerobic threshold (AT) and ventilation/carbon dioxide (VE/VCO2) slope, lipid profiles, blood pressure, arterial stiffness, body mass index (BMI), BMI percentile, and self-efficacy in the intervention group compared to control.
The Stanislas Cohort is a monocentric familial longitudinal cohort comprised of 1006 families (4295 subjects) from the Nancy region recruited in 1993-1995 at the Centre for Preventive Medicine (Centre de Médecine Préventive, CMP), Vandoeuvre lès Nancy for a 5-year periodic health examination, under the auspices of the Caisse Nationale d'Assurance Maladie (CNAM). This cohort was established with the primary objective of investigating gene-gene and gene-environment interactions in the field of cardiovascular diseases, based on the study of inter-individual variability and familial segregation analysis of biological and morphological intermediate phenotypes of cardiovascular risk. The longitudinal nature of this study should enable to take into account the evolution of intermediate phenotypes related to genetic factors throughout the follow-up period. The families, consisting of two parents and at least two biological children, were deemed healthy, free of declared acute and/or chronic illness, in order to assess the effect of genetics on the variability of intermediate phenotypes studied under physiological conditions (without the influence, in the absence) of pathology. The Stanislas Cohort is, both nationally and internationally, the only longitudinal familial cohort of supposedly healthy subjects on such a large scale. Brief summary of ancillary study "Cardiac Functional Indices Comparison Between MRI and Echocardiography" : the ESCIF study is an ancillary study of the Stanislas cohort aiming at comparing in a cohort of supposedly healthy subjects different cardiac functional indices between two different modalities : Echocardiography and MRI. Indeed, new cardiac functional indices have been recently developed in the scope of echocardiography and would be very useful in MRI. In echography they are computed either from tissue Doppler imaging or from a specific image analysis called speckle tracking. These two techniques are accessible in MRI with the Generalized Reconstruction by Inversion of Coupled Systems (GRICS) technology which provides a motion model from which strains and strain rates may be derived and which allow longer acquisition without the constraint of breath holding (mandatory to reach high temporal resolution).
It is well recognized that patients with chronic kidney disease (CKD) have an increased risk for cardiovascular disease (CVD) and hyperhomocysteinemia appears to be a predictor of future CVD events. Hyperhomocysteinemia has been reported to bo of high prevalence in patients with CKD. The investigators aim to study the prevalence of hyperhomocysteinemia in Thai CKD patients by using Thai Screening and Early Evaluation of Kidney Disease (SEEK) study database and their relationship to CVD.
The purpose of this study is to collect and assess information on safety and efficacy of fondaparinux in patients undergoing general surgery of the lower limb at high risk of developing venous thromboembolism.
The purpose of this study is to collect and assess information on safety and efficacy of fondaparinux in patients undergoing abdominal surgery in urology, obstetrics and gynecology departments who are at high risk of venous thromboembolism.
This intervention study will evaluate the feasibility,acceptability and effectiveness of an e-health enabled model of care by randomly assigning a trained patient navigator and/or a blood pressure (BP) self-management web portal to patients with uncontrolled hypertension after a run in period with a home BP monitor (HBPM) and comparing the results on blood pressure control. We anticipate that patients receiving the combination of a patient navigator(PN)with a self-management web portal and home BP monitor will have better BP control than when the only received a home BP monitor.
