Filter by:In the current proposal the investigators seek to evaluate the acute and short-term effects of mango intake on vascular and platelet function in postmenopausal women between 50 and 70 years old. Our aims are 1) to determine if two weeks of daily mango intake will result in favorable changes in measures of vascular function, as measured using peripheral arterial tonometry (PAT) and platelet reactivity, in overweight and obese postmenopausal women. 2) to determine if two weeks of daily mango intake will change the fermentation capacity of gut microbiota. Investigators hypothesize that the daily intake of 330 grams of mango (2 cups) will significantly increase PAT while reducing platelet aggregation after 2 hours and two weeks of daily intake.
The Pitt Retiree Study (PRS) disseminates a novel, yet practical, diabetes prevention program among Medicare eligible adults in Western Pennsylvania. This study will provide 4, and 12 month outcome data (with a no treatment follow-up assessment at 24 months) to help determine whether a continued contact group telephone intervention is feasible and effective in enhancing health outcomes and physical functional ability in high risk adults (aged 65-80) with obesity and cardiometabolic risk factors .
The current study conducted will lend toward the optimization of the development of a food product that will promote a shift towards improved metabolic health. Specifically, this trial will determine the optimal level of protein needed to elicit positive changes in markers of inflammation, metabolic and micronutrient status, hepatic lipid metabolism, vascular function, and the relationship of these changes to the metabolome in school aged children (9 - 13 years of age).
This study is a randomized controlled trial (RCT) and there will be two groups: an intervention group and a control group. Nurse practitioners (NPs) across Newfoundland and Labrador (NL) who agree to participate will be randomly assigned to one of the two groups. The NPs in the intervention group will be asked to screen about 30 individuals aged 40-74 years without established cardiovascular disease (CVD) that currently come to their clinics. The NPs will be asked to screen these patients for CVD using a set of specific data collection tools that will be in electronic format. The control group will carry on with usual practice. Their charts will be reviewed by the researchers at a later date. At the end of the study, the screening program, with tools and strategies for CVD screening, will be given to NPs in the control group.
This platform will enable investigation the cardiovascular risk reduction and the increase in participant engagement in their heart-healthy goals, through the use of virtual care/telemedicine with a digital platform that connects them to their own doctors, nurses, and dietitians.
The aim of this study will be to define the bioavailability and the beneficial properties of coffee bioactive compounds. Moreover, the contribution of cocoa-based products containing coffee to the pool of circulating metabolites will be investigated with the aim of evaluating the effect of the combination of bioactives from different sources. To study the bioavailability of coffee/cocoa bioactive compounds and their effects in cardiometabolic health, the objectives will be: i) Assessing the bioavailability of the four main groups of phytochemicals in roasted coffee (methylxanthines, phenolic compounds, trigonelline, and diterpenes), its modulation by the level of consumption, and establishing the daily average concentration of coffee-derived plasma circulating metabolites; ii) Investigating the effect of different levels of coffee consumption on cardiometabolic risk factors; iii) Evaluating circulating metabolites and their putative bioactivity when substituting coffee consumption with the intake of cocoa-based products containing coffee. A 3-arm, crossover, randomized trial will be conducted. Twenty-one volunteers will be randomly assigned to consume three treatments in a random order for 1 month: 1 cup of espresso coffee/day, 3 cups of espresso coffee/day, 1 cup of espresso coffee at breakfast and 2 cocoa-based products containing coffee two times per day. The last day of the treatment subjects will refer to the ambulatory where blood and urine samples will be collected at specific time points up to 24 hours following the consumption of the testing coffee or of the cocoa-based products containing coffee. In addition to the bioavailability of the bioactive compounds, the effect of the coffee consumption on several cardiometabolic risk factors (blood pressure, anthropometric measures, inflammatory markers, nitric oxide, blood lipids, fasting indices of glucose/insulin metabolism, DNA damage, eicosanoids, nutri-metabolomics) will be investigated. At the end of the treatment, the same protocol will be repeated, switching the allocation group.
This is a randomized controlled trial aimed to design an intensive intervention to modify lifestyles of subjects with intermediate cardiovascular risk and evaluate its effectiveness. 200 participants aged 35-74 years who have intermediate cardiovascular risk will be included. Subjects will be selected by consecutive sampling at urban primary care health centers from Salamanca (Spain) and they will be randomized to a control or an intervention group. Both groups will receive individual standardized counselling on healthy diet, daily physical activity, smoking cessation, and moderation in alcohol consumption. Moreover, individuals from the intervention group will receive additional group counselling and follow-up calls. The effect of the intervention will be assessed using lifestyles and quality of life questionnaires, metabolic control parameters, inflammation markers, anthropometric and vascular function measurements, and neuropsychological tests.
Hot flashes, vasomotor symptoms that affect many postmenopausal women, are associated with cardiovascular disease and endothelial dysfunction. Estrogen therapy, associated or not with progestogens, is the standard treatment for vasomotor symptoms and improves the endothelial function of postmenopausal women with hot flushes, even those with cardiovascular risk factors, such as hypertension. It is not known whether hot flushes are a cause for the development of endothelial dysfunction or are markers of this dysfunction, evidenced by estrogen deficiency, thus representing primitive target organ (vessel) lesion. Paroxetine was approved by the FDA as a non hormonal treatment for menopausal hot flashes. In this double-blind randomized clinical trial, the vascular effects of paroxetine at a dose of 7.5 mg / day, compared to placebo, during 12 weeks are evaluated.
The objective of this study is to determine the effects of consuming either 3 eggs per day as compared to a daily choline supplement (choline bitartrate, 397.5 mg choline/day) on plasma concentrations of High Density Lipoprotein-cholesterol (HDL-C), trimethylamine N-oxide (TMAO), and other biomarkers of cardiovascular disease risk in young, healthy individuals. The goal is to determine if choline given as phosphatidylcholine (eggs) will lead to a different TMAO response when compared to choline in free supplemental form.
Chronic kidney disease (CKD) is estimated to affect 6-8% of the adult population and is independently associated with increased cardiovascular (CV) disease risk. This risk increases as CKD advances both in relation to worsening glomerular filtration rate and development of proteinuria. The overall cost of CKD to the NHS (National Health Service) in England has been estimated as £1.45 billion per annum, or 1.3% of the NHS's total budget. This includes £175 million, or 13% of the CKD budget, annually spent in relation to 19,000 excess myocardial infarctions and strokes related to CKD. The epidemiology of CKD in primary care is poorly studied. This is particularly the case in non-white populations who have an independent higher risk of progression to end stage renal failure (requiring dialysis or transplantation), CV events and death. Further, CV disease risk in CKD remains poorly described beyond simple risk stratification by CKD stage. A recent systematic review identified some CKD-specific CV disease risk scores. However, all the risk scores had significant methodological limitations, such as a lack of external validation or the perception that they were not 'clinically useful'. The Leicester City and County Chronic Kidney Disease (LCC-CKD) cohort will be created from anonymised GP (general practice) records of individuals with CKD. We will aim to retrospectively create a cohort with 5 years follow-up to the present day. In addition, a present day cohort will be created to both aid research and provide data for practices and clinical commissioning groups for quality improvement (QI) purposes. We will aim to include 30,000 individuals with CKD in the cohort. The principal objectives of the study are: 1. To study the natural history of CKD in a multi-ethnic primary care setting 2. To contribute to the creation of a risk prediction tool for heart attacks and strokes in CKD The risk prediction tool would more accurately stratify risk of CV events for individuals with CKD. This would aid patients and clinicians in deciding on treatments aimed at reducing the risk of future myocardial infarctions and strokes. Currently, individuals with CKD, despite higher risk of CV disease, may not be receiving optimum treatment such as statins and anti-hypertensive medications. Improved management of cardiovascular risk factors in CKD is likely to see a reduction in CKD associated excess CV events and their associated costs, including longer average duration of inpatient admissions.
