Filter by:The purpose of the study is to find out the effects of neighborhood disadvantage and sleep disparities contribute to racial disparities in cardiometabolic health and blood pressure in young adults.
The overall objective of Phone-based Intervention under Nurse Guidance after Stroke II (PINGS-2) is to deploy a hybrid study design to firstly, demonstrate the efficacy of a theoretical-model-based, mHealth technology-centered, nurse-led, multi-level integrated approach to substantially improve longer term BP control among 500 recent stroke patients encountered at 10 hospitals in Ghana. Secondly, PINGS II seeks to develop an implementation strategy for routine integration and policy adoption of mhealth for post-stroke BP control in a LMIC setting. The investigators will leverage experience gained from the NIH Global Brain Disorders funded R21 pilot study (NS094033) to test efficacy of a refined, culturally-tailored, and potentially implementable intervention aimed at addressing the premier modifiable risk for stroke & other key variables in an under-resourced system burdened by suboptimal care & outcomes.
This prospective study aims to assess the feasibility and implementation of a plant-based, weight-loss program in an office setting. The study will also assess changes in body weight, blood pressure, plasma lipids, glycated hemoglobin, and body composition with a 12-week, plant-based, weight-loss program. These health benefits may illustrate feasibility to physicians and healthcare professionals elsewhere.
Elevated blood pressure (BP) consists of a major public health concern especially in low and middle income countries. Besides being a highly prevalent condition, it is also a risk factor for several major cardiovascular events including stroke (which consists of the second leading cause of death in developing countries) and coronary artery disease, and is also related to cognitive decline. The OPTIMAL Stroke trial consists of a two-arm, multicenter, randomized clinical trial designed to test whether a lower target systolic blood pressure (SBP) as compared to the currently recommended target for stroke patients will reduce the occurrence of major cardiovascular events.
The primary objective is to examine the impact of the Renin-Angiotensin-Aldosterone System (RAAS) blockade with medications (valsartan) or RAAS and neprilysin inhibition (valsartan/sacubitril) vs. placebo on changes in blood sugar and insulin secretion from the pancreas over 26 weeks assessed with glucose clamp studies among African Americans (AAs) with impaired glucose tolerance. The investigators hypothesize that combined RAAS/neprilysin inhibition will lead to greater improvement in insulin release from the pancreas and improved blood sugar compared to RAAS inhibition alone among AAs with impaired glucose tolerance.
This study will test the effect of race-based social rejection on polysomnography derived sleep outcomes and nocturnal cardiovascular psychophysiology in a sample of 80 African Americans and 80 Caucasian Americans. The investigators will test group differences on these outcomes as well as within subjects by testing impact of rejection compared to a non-rejection control night in the sleep laboratory.
Caretaker vs. Blood Pressure Monitoring With Invasive Arterial Pressure Monitoring in Patients With Septic Shock
Perioperative organ injuriy remain an important threat to patients undergoing major surgeries. Intraoperative hypotension is associated with an increase in postoperative morbidity and mortality. Whereas individualized intraoperative blood pressure management is likely to decrease the incidence of postoperative organ injury when compared with standard blood pressure management strategy. Dexmedetomidine, a highly selective alpha2 adrenergic agonist, has been shown to provide organ protective effects. This study aims to investigate the impact of intraoperative goal-directed blood pressure management and dexmedetomidine infusion on incidence of postoperative organ injury in high-risk patients undergoing major surgery.
Home blood pressure measurement has been reported to be associated with better clinic blood pressure and daytime blood pressure control. However, no study has evaluated the association between home blood pressure measurement and control of 24-hour ambulatory blood pressure in real world practice. The purpose of the present study is to investigate the effect of home blood pressure measurement on the control of ambulatory blood pressure in the real world. The detailed purposes of the present study are (1) to investigate the effects of home blood pressure measurement on the appropriate control of 24-hour ambulatory blood pressure in hypertensive patients treated with antihypertensive drug, (2) to evaluate the effect of home blood pressure measurement on the occurrence of cardiovascular events and target organ damage, (3) to investigate the status and appropriateness of home blood pressure measurement in the real world, and (4) to investigate factors of home blood pressure measurement methods affecting the treatment of hypertension.
The investigators hypothesize that compared to untreated controls, erythropoietin (EPO) therapy in anemic patients with chronic kidney disease will raise diastolic blood pressure (BP). The magnitude of increase in diastolic BP at 12 weeks after treatment will be related to two factors. First, endothelial dysfunction and worsening of endothelial function from baseline to 4 weeks and second, the change of forearm blood flow in response to breathing oxygen and the change in this measure from baseline to 4 weeks. Study procedures include fasting blood draws, ambulatory blood pressure, urine collection, and forearm blood flow tests. The study hopes to accrue 160 subjects.
