Filter by:The proposed ONE TEAM Study is an 18-month, cluster randomized controlled trial. This study will use a sequential multiple assignment randomized trial (SMART) design with a second randomization for the intervention group using a dynamic treatment regimen approach. The investigators propose to randomize 800 adults with newly-diagnosed selected cancers treated with curative intent (breast, prostate, colorectal, endometrial, non-small cell lung, and endometrial) and with >1 selected cardiovascular disease (CVD) comorbidity (hypertension, type 2 diabetes mellitus, hypercholesterolemia). Participants will be enrolled through Duke Cancer Institute and two community-based oncology practices, both settings serving socio-demographically diverse populations. The unit of randomization will be the PCP clinic; there will be ~80 PCP clinics across North Carolina involved in the study. The overarching goals of this study are to improve chronic disease management and communication among cancer survivors by engaging PCPs as active members of the cancer care team and reframing the message to cancer survivors and providers. A diversity supplement with retrospective and qualitative components has been added to abstract older adults with solid tumors who underwent cancer surgery at DUHS. Aims include (1) to estimate the prevalence of cardiovascular complications ≤90 postoperative days among older adults with solid tumors undergoing surgery, and its association with care coordination between surgical providers and PCPs ; (2) to develop a risk index for cardiovascular complications ≤90 days of surgery among older adult patients with a solid tumor; and (3) to Assess experience and perceptions of PCPs on care coordination with surgical providers of older adults with a solid tumor following cancer surgery.
Nearly nine-in-ten Americans overconsume salt. Black individuals are more prone to salt-sensitive hypertension. The central goal of the study is to determine if dietary sodium influences blood vessel function and nervous system regulation of blood pressure differentially in black, compared to white individuals. These findings may help to explain why high dietary salt causes increases in blood pressure more frequently in black, compared to white individuals. A secondary goal of this project is to also determine the role of lifestyle factors (i.e., sleep, physical activity, and nutrition) on potential baseline racial differences in cardiovascular function.
This study will examine markers of vascular endothelial function (vascular health) and metabolic profiles in older versus younger transgender men (people who were assigned female at birth but whose gender identity is male). Data will also be compared to those from age group-matched transgender women and cisgender women and men.
The purpose of the study is to investigate the association between inpatient blood pressure levels and in-hosopital adverse outcomes.
The primary objective of this research is to collect data to develop an algorithm for continuous, non-inflating measurement of absolute, long-term Blood Pressure using the CS6BP device and to evaluate the safety of the CS6BP.
China is entering an aging society. As the number of elderly population continues to increase, the elderly are facing many social problems that deserve the attention of all sectors of society. Hypertension is one of the common diseases in the elderly population. Hypertension is the most common chronic diseases and a most important risk factor for cardiovascular and cerebrovascular diseases, and also a substantial public health problem. Home blood pressure monitoring is simple, not only can find hypertension, but also can guide the treatment of patients with hypertension. The purpose of the study is to investigate the association between home blood pressure and adverse outcomes in community elderly population.
This study will incorporate critical cross viscero-visceral intersystem interactions to 1) investigate in a controlled laboratory setting and then with mobile at-home monitoring the extent, severity, and frequency of occurrence of autonomic dysreflexia with respect to daily bladder and bowel function, in conjunction with identifying potential underlying mechanisms by examining urinary biomarkers for several specific vasoactive hormones, and 2) to regulate cardiovascular function therapeutically as part of bladder and bowel management using spinal cord epidural stimulation.
1. Statement of the research question: Does the caffeine in energy drinks interact with other ingredients to affect cardiovascular function in healthy male and female adults after exercise? 2. Purpose and significance of the study: Energy drinks are beverages promoted to enhance alertness along with athletic and cognitive performance. The most common ingredients found in energy drinks include water, sugar, caffeine, taurine, and B-vitamins, with variable inclusion of other ingredients, such as carnitine, glucuronolactone, inositol, guarana, ginkgo biloba leaf extract, thistle extract, and ginseng root extract. Since the mid-1990s, the consumption of energy drinks has grown dramatically, with worldwide sales in 2017 exceeding $49 billion. As the sale of energy drinks has grown, so has the number of adverse event case reports for patients who consumed energy drinks. Reported symptoms included cardiac arrhythmias such as ventricular fibrillation, atrial fibrillation, and cardiac arrest. A few small clinical studies have found that energy drinks can increase systolic and diastolic blood pressure and change electrical activity in the heart as measured by an electrocardiogram (ECG). The intent of the proposed study is to determine whether caffeine or the combination of caffeine with taurine and L-carnitine can alter cardiovascular function. Hypothesis: The effects of the ingredients of energy drinks on the heart are mediated in part by interactions between caffeine, taurine and carnitine. The amount of each ingredient in the study was based upon the amount commonly contained in two cans of energy drinks currently on the market.
In recent years, with the investment from government in the health management of the elderly, community management of hypertension in the elderly has made great progress in management rate and standardized management, but the management of young and middle-aged patients with hypertension is still blank. Workplace pressure measurement may be more suitable for most of the young and middle-aged patients to find high blood pressure and monitor blood pressure changes in time. However, there is not much research on workplace pressure measurement. Whether blood pressure measurement in the workplace can reduce the white coat effect, and how it relates to home blood pressure and ambulatory blood pressure is still unclear.
Approximately 50% of patients in the intensive care unit (ICU) develop acute kidney injury (AKI) and more than 10% need dialysis. There is no treatment for AKI. Care is aiming for optimization of circulation and blood flow to the kidneys and avoiding nephrotoxic agents. There is conflicting data concerning whether early or late dialysis is harmful for the kidneys. No one has examined the physiological changes in the kidney when starting dialysis and which blood pressure that leads to most optimal physiological conditions for the kidneys during dialysis. In this descriptive study of 20 ICU patients suffering from AKI we aim to investigate renal physiology when starting continuous renal replacement therapy (CRRT) and also at different target blood pressures using retrograde renal vein thermodilution technique. In parallel we will also investigate and validate this invasive method with contrast enhanced ultrasound of the kidneys.
