Filter by:This study will assess the amount of energy that the heart will deliver to the central circulation and the efficiency of that energy transfer, in patients undergoing a coronary artery bypass graft operation. Measurements will be taken just after induction of anaesthesia and repeated just after the end of the operation. The total energy delivered by the heart will be calculated by multiplying a pressure curve from the artery in the hand with the instantaneous ultrasound recorded cardiac output flow curve. The energy responsible for the acceleration of the blood volume, known as oscillatory power will also be calculated. The energy transfer will be calculated using a mathematical model based upon other ultrasound and blood pressure recorded variables. We would like to see if any alteration in energy delivered is in part due to impairment in energy transfer or alteration of fraction of oscillatory power rather than a change in total energy production. We would also like to study if there are changes in the oscillatory power after cardiac bypass surgery. The patients will be sampled sequentially into the study. We are not aware of any such studies undertaken in humans previously.
A two-period randomized crossover study will be conducted to determine the effect of peanuts on glycemic control, and elucidate the role of the microbiome in glucose regulation, in individuals with impaired fasting glucose.
To evaluate the safety, tolerability, PK and immunogenicity of single and multiple ascending doses of MEDI6570 in subjects with Type 2 Diabetes Mellitus
Metabolic Syndrome (MS) contributes to the development of cardiovascular diseases (CVD). According to the World Health Organization (WHO), CVDs are the leading causes of death in the world. According to epidemiological data from the Ministry of Health, these diseases account for 29.4% of all deaths recorded in Brazil annually. Kefir is obtained by fermenting milk with kefir grains and has been recommended as a therapeutic form for the treatment of various clinical conditions. The hypothesis of the present study is that the daily intake of fermented beverages with kefir grains may reduce the risk factors associated with MS, thus reducing the incidence of CVD. A clinical trial was conducted with 48 volunteers, who presented at least three criteria for the diagnosis of MS. The subjects were divided into two groups that received for eleven weeks fermented dairy drink with kefir (KG) grains or homemade curd (CG). Weight and height measurements were taken to calculate BMI. The body composition evaluation was performed by determining the percentage of body fat and waist circumference (WC). The measurements of systolic blood pressure (SBP) and diastolic blood pressure (DBP) were taken. Blood samples were analyzed for fasting glycemia, glycated hemoglobin (HA1c), total cholesterol (TC), HDL cholesterol, triglycerides (Tg), C-reactive protein (CRP), aspartate aminotransferase (AST), Alanine Aminotransferase (ALT), Creatinophosphokinase (CPK), γ-Glutamyl Transferase (γ-GT), Urea Nitrogen, Urea and Creatinine. The level of non-HDL cholesterol (n-HDL) was determined by calculation. The Framingham score was used to assess the risk of developing cardiovascular events over the next ten years. Eleven weeks into the experiment, all measurements of body evaluation, SBP and DBP and biochemical analysis of blood were reevaluated.
The benefits of cardiac rehabilitation are well known. However, despite center based cardiac rehabilitation (CBCR) representing guideline-based care for patients with cardiovascular disease, most patients do not complete the maximum number of sessions allowed by third party insurance payers. As such, many patients may not be receiving the full clinical benefit ascribed to CR. This study will assess the efficacy of an innovative approach to CR delivery on attendance by combining both center-based and remote- or home-based CR sessions. The intervention group combines center-based CR and remote-/home-based CR and is tailored to the individual needs of each patient, accomplished with the assistance of an easy-to-access telecommunications methodology (telemedicine)
This pilot study will use a hybrid reciprocal peer support and peer coach model to initiate and sustain heart-healthy behavioral changes in Veterans. Veterans who are at-risk for cardiovascular disease (CVD) will be enrolled in the study and paired with another Veteran to receive and provide social support around engaging in CVD risk reduction behaviors. Enrolled participants will be offered a series of 3 group sessions focused on CVD risk reduction, goal setting and action plan development. Between group sessions, peer partners will be asked to have weekly calls to discuss action plan challenges, explore options for problem solving, and provide encouragement and accountability for personal goals. Participants who do not engage in the group sessions or weekly phone calls, or who request additional help, will receive support from trained peer coaches. The goal of this pilot study is to evaluate the proof of concept for a hybrid reciprocal peer support (RPS) and peer coach intervention to improve heart healthy behaviors among Veterans at risk for CVD.
Switching patients with HIV infection from tenofovir disoproxil fumarate (TDF) to a tenofovir alafenamide (TAF) based drug regimen can provide many safety benefits including preserving bone mineral density and kidney function. This study will examine metabolic changes that patients may encounter due to the switch in medication regimens and the maintenance of viral suppression.
Strategies to improve uptake of cardiovascular disease preventive therapies among people living with HIV (PLHIV) are urgently needed. This study tests an innovative prevention nurse intervention to extend the HIV/AIDS treatment cascade for the treatment of hypertension and hyperlipidemia among PLHIV on suppressive antiretroviral therapy. This intervention may be scalable as an extension of ongoing HIV/AIDS treatment cascade initiatives in HIV specialty clinics nationwide.
The objective of the proposed project is to evaluate the usability, acceptability, and adherence of a lifestyle and behavioral self-tracking and ePersuasive tool aimed at improving: 1) adherence to diet/nutrition (<1500 mg of sodium/day and less than 10% daily free sugar intake), physical activity (PA) (150 minutes of moderate PA/week), and sleep guidelines (7-8 hours of sleep/day)-- and 2) control 3% reduction in systolic BP and glucose from baseline to end of study follow-up after 2 months (exploratory objective) in a sample of 20 patients with Hypertension or Diabetes. The study will utilize a Step-Wedge Design where the 20 patients will be divided into 4 wedges (5 patients in each wedge).
Cardiovascular disease (CVD) is the largest concerns for patients with Chronic kidney disease (CKD). At present time the investigators do not have proven effective strategies to reduce high CVD related deaths in CKD. This study assesses a novel therapy (hydroxychloroquine, HCQ) for the treatment of CVD in patients with CKD. This is the first human proof-of-concept study and is planned to be conducted among US Veterans, who suffer from both CKD and CVD at a disproportionately greater rates. The outcome of this study has the potential to provide an entirely new line of therapy for the treatment of CVD in CKD.
