What is the cumulative incidence, types and severity of HTN medication-related adverse events and their predictors among PLHIV with HTN? We will use qualitative research methods to explore key stakeholders' perspectives and preferences on integrating hypertension care in community ART delivery models in Uganda; design implementation strategies that integrate the management of hypertension into existing community ART delivery models; determine the effectiveness of implementation strategies that integrate the management of hypertension in community ART delivery models; evaluate implementation outcomes of strategies that integrate hypertension care in community ART delivery models; determine the cumulative incidence, types and severity of medication-related adverse events and their predictors; and assess the patients and provider costs, health related quality of life, cost-effectiveness of leveraging existing HIV differentiated service delivery models to screen and treat HTN among persons with HIV in Uganda.
The aim of the study is to observe the change of the circulating MrgD level in patients with pulmonary hypertension compared with subjects without pulmonary hypertension.
A randomized trial of remote blood pressure monitoring, compared to usual care, in patients receiving bevacizumab to determine whether remote blood pressure monitoring improves the collection of blood pressure data, identification and management of clinically significant hypertension, and patient satisfaction.
The goal of this pilot clinical trial is to evaluate a culturally tailored computerized education program in hospitalized African-American patients with advanced chronic kidney disease (CKD). The main question it aims to answer are: does computerized adaptive education (CAE) increase patients' knowledge about CKD self-care and renal replacement therapy (RRT) options compared to usual care (UC) and will CAE will be increase patients' intent to participate in CKD self-care and RRT preparation compared to UC
Our long-term goal is to better understand novel interventions to promote cardiovascular health in humans. The goal of the proposed research is to investigate whether there is sex-specificity in the effects of dietary capsaicin on mechanisms regulating nitric oxide (NO) bioavailability, its effect on key markers of cardiovascular health, including BP, macro- and microvascular function, and arterial stiffness. This knowledge will provide critical insight into the effects of dietary capsaicin on CV health and will guide future trials.
In chronic kidney disease (CKD), hypertension is characterized by the phenomenon of sodium-sensitivity, i.e., the disproportionate increase in blood pressure (BP) due to an increase in dietary sodium consumption to maintain homeostasis through urinary sodium excretion. Impaired renal circulation, blunt suppression of renin-angiotensin-aldosterone system, sympathetic nervous system overactivity, paradoxically reduced levels of atrial natriuretic peptide and hyperinsulinemia represent the main pathophysiologic mechanisms. Accumulated evidence has suggested that uromodulin plays a central role in the development of sodium-sensitive hypertension. Uromodulin is a kidney-specific glycoprotein which is exclusively produced by the epithelial cells lining the thick ascending limb and early distal convoluted tubule. It is currently recognized as a multifaceted player in kidney physiology and disease, with discrete roles for intracellular, urinary, interstitial and serum uromodulin. Among these, urinary uromodulin modulates renal sodium handling through regulating tubular transporters that reabsorb sodium and are targeted by diuretics, i.e., the loop diuretic-sensitive Na+-K+-2Cl- cotransporter type 2 (NKCC2) and the thiazide-sensitive Na+/Cl- cotransporter (NCC). Given these roles, the contribution of uromodulin to sodium-sensitive hypertension has been proposed. In preclinical models, uromodulin deficiency causes decreased BP that is resistant to dietary salt, while uromodulin overexpression causes hypertension due to increased tubular sodium reabsorption that is responsive to furosemide. Genetic human studies have identified robust associations of specific UMOD gene variants with sodium sensitivity and incident hypertension risk, while comprehensive Mendelian randomization studies have affirmed these associations by highlighting the causal relationship between UMOD variants, urinary uromodulin levels and hypertension. Furthermore, clinical studies in both healthy individuals and hypertensive patients have indicated a link between sodium sensitivity and uromodulin, directly affecting mean BP levels and BP response to salt intake. With regards to CKD population, solid data on the link of uromodulin with sodium sensitivity are currently missing from the literature. There is only a pediatric study in the setting of CKD (stages 2-3), which failed to show an association between urinary uromodulin levels indexed to urinary creatinine (UMOD/uCr) and either 24-hour or office BP; however, this study has several limitations, and its results should be interpreted with caution. To best of our knowledge, there is no study up to date investigating the effect of dietary sodium intake on 24-hour ambulatory blood pressure depending on urinary uromodulin levels in adult CKD patients.
The goal of this clinical trial is to learn the effectiveness of remote home-based exercise rehabilitation using mobile Internet technology for patients with pulmonary hypertension，especically providing early and mid-term results of its effectiveness. The main questions it aims to answer are: Dose tele-rehabilitation training improves prognostic function and quality of life in patients with pulmonary hypertension？ Researchers will compare tele-rehabilitation training group to a control group (receive health propaganda and education, and then follow their daily routine after discharge from the hospital) to see if tele-rehabilitation training works to improve prognosis. Participants will: During their stay in the hospital, the patients of tele-rehabilitation training group were accompanied by a rehabilitation trainer and a psychotherapist for a complete cycle of (7 days ± 3 days 1 week/times) standardized training. The scheme of rehabilitation is impedance training. A specialized professional team including cardiologists, rehabilitation trainers, psychotherapists and radiologists were involved. After discharge from the hospital, patients in the rehabilitation group underwent 3-5 weekly daily training sessions and intensive supervision and management by the online community at least once a week. Visit the clinic at the 3rd month of the study. Extended follow-up up to 6 months may be considered if patients are cooperative and could complete the training program in the first 3 months.
Emerging data connect diet, the gut microbiota and its metabolites in cardiometabolic disease. Hypertensive disorders of pregnancy (HDP) are common and are a leading cause of maternal and neonatal morbidity. HDP likely share similar pathophysiology as cardiometabolic disease in non-pregnant people with a yet unrevealed role of diet and the gut microbiota, including systemic inflammation and endothelial dysfunction. Despite high biological plausibility that nutrition, the gut microbiota and its metabolites may play a role in health and disease in pregnancy, there is a paucity of data regarding these associations, thus limiting advancement of the field. Similar to the proposed pathogenesis for diet, gut microbiota and the microbial metabolite trimethylamine-N-oxide (TMAO) in cardiovascular disease, we hypothesize that the interplay between maternal diet, the gut microbiota and its associated microbial metabolites play a mechanistic role in HDP. We propose to test this hypothesis in a racially-diverse US cohort to determine association with adverse pregnancy outcomes, specifically future development of HDP. We propose to prospectively collect plasma and urine TMAO throughout pregnancy from a cohort of 200 pregnant participants. Through 1) characterizing plasma and urine TMAO levels across each trimester of pregnancy, and 2) assessment of this microbial metabolite as a predictor of development of HDP, we have the potential to identify a biomarker that would allow us to identify people at risk of HDP early in pregnancy and provide new opportunities for therapeutic interventions to improve maternal and neonatal outcomes.
