Filter by:This study aims to learn about the effects of continuous positive airway pressure (CPAP) on people with autonomic failure and high blood pressure when lying down (supine hypertension) to determine if it can be used to treat their high blood pressure during the night. CPAP (a widely used treatment for sleep apnea) involves using a machine that blows air into a tube connected to a mask covering the nose, or nose and mouth, to apply a low air pressure in the airways. The study includes 3-5 days spent in the Vanderbilt Clinical Research Center (CRC): at least one day of screening tests, followed by up to 3 study days. Subjects may be able to participate in daytime and/or overnight studies. The Daytime study consists of 2 study days: one with active CPAP and one with sham CPAP applied for up to 2 hours. The Overnight study consists of 3 study nights: one with active CPAP, one with sham CPAP, both applied for up to 9 hours and one night sleeping with the bed tilted head-up.
The overall goal of this study is to identify and rigorously evaluate strategies for implementing and sustaining team-based home blood pressure monitoring (TB-HBPM) within primary care. The TB-HBPM intervention is a multifaceted program involving patient transmission of blood readings to EHR and clinical decision support. Implementation strategies include group-based education on hypertension measurement, target blood pressure goals, drug and lifestyle management, referral to community resources, and team training designed to optimize the coordination of hypertension care, and monthly audit and feedback reports to teams and clinicians. Hypertension control rates are suboptimal in many primary care practices with persistent racial disparities in control. Team-based home blood pressure monitoring (TB-HPBM) involving patient transmission of their home blood pressure readings in real-time to their clinical team has been shown to improve blood pressure control. There is an urgent need to implement TB-HBPM into practice. The overall objective of this research is to assess implementation strategies that mitigate barriers and leverage facilitators to TB-HBHM on hypertension control and disparities between Black and White patients. The study team and investigators will use mixed methods to assess the process and generate knowledge to facilitate broader uptake of TB-HBPM.
The proposed project is a 24-week prospective randomized controlled trial (RCT) evaluating the effects of TargEted MAnageMent Intervention (TEAM, N=25) vs. enhanced wait-list (eWL, N=25) control in depressed young (<50 years) African-American (AA) women at risk for hypertension.
High blood pressure is the leading risk factor for heart disease and stroke. Approximately 12% of the population have a particular genetic factor (known as the TT genotype) which increases the risk of high blood pressure. Previous studies conducted at this centre have shown that taking the B-vitamin riboflavin, for up to 3 months, decreases blood pressure in adults with the TT genotype. It is currently not known how riboflavin lowers blood pressure in those with the TT genotype but it could be as a result of altering blood levels of nitric oxide. Nitric oxide causes blood vessels to expand, leading to improved blood vessel function, an important predictor of cardiovascular health. However, the effect of riboflavin supplementation on nitric oxide and blood vessel function has not been previously studied. Furthermore, it is unclear whether taking riboflavin over a shorter period of time or at doses higher than 1.6 mg/d can also lower blood pressure and improve blood vessel function in this at risk group. Therefore, the aim of this study is to assess the effects of riboflavin supplementation on blood pressure, biomarkers of nitric oxide bioavailability and blood vessel function. It is hypothesised that riboflavin supplementation will increase nitric oxide bioavailability, leading to reduced blood pressure and improved blood vessel function and, and that a higher riboflavin dose will lead to greater reductions in blood pressure.
Hypertension, diabetes, and obesity are considered major risk factors for cardiovascular diseases and premature mortality worldwide. Furthermore, they have severe consequences on quality of life among patients. With increasing challenges facing the healthcare systems, pharmacists are well positioned to take on a greater role in the management of chronic diseases. The present study aims to investigate the impact of pharmacist counselling on the clinical outcomes (weight, mortality, blood pressure, blood glucose) of hypertensive, diabetic, and obese patients.
Chronic diseases are the leading cause of deaths in Singapore. The rising prevalence in chronic diseases with age and Singapore's rapidly aging population calls for new models of care to effectively prevent the onset and delay the progression of these diseases. Advancement in medical technology has offered new innovations that aid healthcare systems in coping with the rapid rising in healthcare needs. These include mobile applications, wearable technologies and machine learning-derived personalized behaviorial interventions. The overall goal of the project is to improve health outcomes in chronic disease patients through delivering targeted nudges via mobile application and wearable to sustain behavioral change. Our overall objective is to design, develop, and evaluate an adaptive intervention platform on wearable devices and shared decision-making during consultations for patients with diabetes and hypertension. Our aim for this study is to assess the clinical effectiveness of real-time personalized educational and behavioural interventions delivered through wearable (Fitbit) and an integrative mobile application in improving patient glycaemic control measured using HbA1c over 9 months. Secondary outcomes will include change in systolic blood pressure, quality of life (QoL), patient activation, medication adherence, physical activity level, diet, direct healthcare cost and indirect healthcare cost over 9 months. We will conduct a randomized controlled trial among patients with comorbid diabetes and hypertension. This proposal aims to develop sustainable and cost-effective behavioural change among patients with comorbid diabetes and hypertension through patient empowerment and targeted chronic disease care.
To evaluate whether atorvastatin can improve portal hypertension in patients with chronic hepatitis B related compensated cirrhosis with portal hypertension
The goal of this study is to support patients with hypertension self-management using both home blood pressure monitors and digital messaging programs. The investigators will first engage patients with technology training to use home monitors, online portal websites to view their medical record information online, and texting and mobile phone applications. Then investigators will assess the effectiveness of home blood pressure monitors and enhanced patient-clinician digital communication on blood pressure control during a 12-month intervention.
Two arm parallel randomized clinical trial
This is a single group study assessing the feasibility of hypertension management by community health workers (CHWs) equipped with a mobile clinical decision support (CDS) application and working with remote physician supervision.
