Filter by:CVD accounts for 15% of all deaths in Malawi. Both HIV and ART are risk factors for CVD through direct toxic and inflammatory cardiovascular effects. (44,45). At the moment, one out of every 10 Malawian is HIV positive and roughly 8 out of 10 of those infected are now on ART (2). Therefore, HIV and ART may be contributing to the burden of CVD in Malawi. Currently, there are only a few studies assessing CVD risk in the HIV patient population on ART. In Malawi, no such studies exist. Therefore, the investigators propose a novel study assessing baseline cardiovascular disease risk using two novel ultrasound technologies in HIV patients on ART. Cardiovascular disease risk will be assessed using surrogate cardiovascular markers of disease. These surrogates include markers of endothelial function and cardiovascular modulating inflammatory biomarkers. The inflammatory biomarkers measured will be TNF-alpha, IL-6, and CRP. Aspirin, by way of its antiplatelet and anti-inflammatory effect has been demonstrated to inhibit atherosclerosis by way of decreasing TNF-alpha, IL-6, CRP and improving endothelial function. Therefore a second aim of the study will be to demonstrate that aspirin improves surrogate markers of atherosclerosis.
Background: Although remifentanil based anesthesia has been preferred for fast-track cardiac anesthesia, its recovery profile in cognitive function has not been investigated. Authors determined postoperative Bispectral index (BIS) score as well as extubation time after remifentanil-based propofol-supplemented anesthesia and compared them with those after conventional balanced sevoflurane-sufentanil anesthesia. Methods: Patients undergoing cardiac surgery using moderate hypothermic cardiopulmonary bypass (CPB) will be randomly allocated to get remifentanil-based propofol-supplemented (Group R) or conventional sevoflurane-sufentanil regimen (Group C) in the study period. For anesthetic induction and maintenance, fixed target controlled infusion (TCI) of remifentanil (plasma concentration 20 ng/ml) and TCI-propofol for maintaining BIS score 40-60 (effect concentration 0.8-1.5 μg/ml) in Group R, and TCI-sufentanil (Cp 0.4- 0.8 ng/ml) and sevoflurane inhalation for maintaining 80-120 % of baseline BP and BIS < 60 (< 1.5 MAC) in Group C, respectively. Authors will analyze postoperative recovery of cognitive function by using BIS after the use of remifentanil-based propofol-supplemented anesthesia for cardiac surgery and to compare them to those after the use of conventional balanced sevoflurane-sufentanil anesthesia.
South Asians have a much higher risk of diabetes compared to Europeans and investigators don't know why this is. Investigators think that South Asians' capacity to store fat safely under the skin is lower than Europeans, so they start to store fat around internal organs and in liver and muscle, and at lower body weights than Europeans. These increased levels of internal fat storage are thought to increase risk of diabetes. The purpose of the study therefore is to investigate whether there are differences with weight gain and weight loss in fat storage, fat cell function and metabolic risk factors, in South Asians compared with Europeans. Investigators will compare South Asian and European men at the start of the study, after they have gained about 7% body weight, and again after they have lost 7-15% body weight (from peak weight) to see how gaining and losing weight affects fat storage within the body and the function of fat cells. Investigators will also assess the effect of weight gain and weight loss on metabolism, fitness and risk factors for diabetes and heart disease.
The purpose of the COPPER - B study is to assess the feasibility, safety, and initial efficacy of paclitaxel administration using the OPC for the prevention of restenosis in infrapopliteal de novo and restenotic lesions and occlusions using a novel catheter, the OPC.
The purpose of this study is to evaluate the clinical outcomes of transcatheter aortic valve replacement (TAVR) in patients with bicuspid aortic valve stenosis.
BACKGROUND: The Southern European Atlantic Diet (SEAD) is the traditional diet of Northern Portugal and Galicia, a region in northwest Spain. The SEAD has been associated with a lower risk of non-fatal acute myocardial infarction. Possible mechanisms of this association may be related with a lower concentration of markers of inflammation and with reduced triglycerides, insulin, insulin resistance, and systolic blood pressure. Aim: To evaluate the effect of an Atlantic Diet on i) lipid profile, ii) markers of inflammation, and iii) anthropometric indices in a population-based study METHODS: This is a non-pharmacological clinical trial study which is performed on a family-oriented basis. 250 families (~ 750 children and adults, older than 3 years) were selected to participate in the study and randomized into Atlantic Diet (AD) (n=125 families) and control (n=125 families) groups. The AD groups participate in a diet program 1 day a month for 3 months in 120-minute diet sessions and freely receive AD food, characterized by a high intake of vegetables, cheese, olive oil, mussels and by wine consumption during meals. Control group subjects do not participate in any regular diet activity during this period and did not receive additional food. Exclusion criteria are alcoholism, lipid treatment, dementia, and terminal disease. Weight, BMI, waist circumference (WC), skin folds, nutrient intake from 3-day recalls, food frequency questionnaire, physical activity, blood pressure, metabolic function (fasting blood glucose, HBA1c, insulin resistance and lipid profile), and inflammation markers (c-reactive protein, interleukin 6 and tumor necrosis factor-alpha) are measured at baseline, 3 and 6 months. Mixed effect models will be performed to assess the significance of changes in the cardiometabolic parameters. The primary end point is the change in lipid profile compared with baseline and the control group arm at the end of Month 6. The secondary exploratory end points were change in anthropometric indices and inflammation markers at Month 6.
The purpose of this study is to evaluate the effect of MLN1202 on arterial inflammation in participants with stable atherosclerotic cardiovascular disease (CVD) who are receiving standard-of-care (SOC) therapy.
The investigators propose conducting a pilot study to identify 6 worksites (2 India, 2 Sri Lanka, 2 Bangladesh) explore barriers to optimum cardiovascular disease(CVD) care at these worksites, quantify risk factor level in worksite populations and identify and train peer mentors to deliver an educational intervention to improve life style and enhance medication adherence among those at moderate to high risk of cardiovascular disease (CVD).
The aim of this study is the comparison between the effects of supplementation with omega 3 or placebo for 8 weeks in serum level of BDNF، Follistatin، Irisin in patients with cardiovascular disease.
Cardiac output monitoring is mandatory in most surgical and critical care patients. Many techniques to assess cardiac output are invasive and/or have many limitations, contraindications and drawbacks. The measurement of cardiac output throughout the CO2 signal is an interesting option due to the simplicity and non-invasive nature of its calculation. The present study was designed to compare the cardiac output measurement using a capnodynamic formula versus the reference thermodilution method.
