Filter by:The investigators' long-term goal is to develop tailored interventions to influence self-management behaviors in young adults with elevated blood pressure (BP). The investigators seek to test an intervention, mHealth to Optimize BP Improvement (MOBILE), that takes advantage of existing applications and our prior work to allow participants to (1) perform self-measured BP monitoring; (2) receive feedback from a cloud-based cardiovascular disease (CVD) detection platform; and (3) receive tailored text messages that encourage engagement in BP reduction behavior. mHealth technology provides an ideal way to deliver healthcare interventions to young adults. Text messaging is especially appealing to college students, more than 91% of whom use smartphones as their main communication device. For this study, the investigators will recruit 42 college students, ages 18 to 29, with elevated BP to participate in formative developmental project and then a 4-week two-armed trial of MOBILE. The aims of this study are: Aim 1. To refine the MOBILE intervention during a formative phase involving 8-10 students. Outcomes will include finalized motivation-level-tailored text messages designed to prompt behavior change and a self-administered motivational scale to be employed in the Aim 2 and Exploratory Aim study. Aim 2. To evaluate the feasibility of implementing the MOBILE intervention in 32 college students with elevated BP. The investigators will operationalize MOBILE feasibility as: (a) acceptability to participants, (b) participation rate, (c) texts delivered and opened, (d) fidelity to daily BP measurement protocol, (e) reported technical problems and challenges, and (f) recruitment and attrition rates. Exploratory Aim. To examine the preliminary impact of the MOBILE intervention on BP reduction (primary outcome) along with sodium intake and hypertension (HTN) knowledge improvement (secondary outcomes) among 32 college students with elevated BP. Hypothesis: The intervention group will have a significantly greater reduction in BP and sodium intake and greater increase in HTN knowledge from baseline to completion, compared to control group.
Obesity in adolescents is associated with the development of cardiovascular disease and type 2 diabetes mellitus. In order to detect early development of cardiovascular disease, early detection of the endothelium of obese adolescents is needed. Endothelium dysfunction is an early stage of developing atherosclerosis, which can be a predictor of cardiovascular disease development in the future. Flow mediated dilatation (FMD) is a non-invasive method that can measure endothelium function and predict the risk of cardiovascular disease, which is not only able to measure artery diameter, but also provides function index of nitric oxide (NO) in the endothelium. FMD is negatively related to BMI. Meanwhile, Endothelin-1 (ET-1) is thought to play a role in the pathogenesis of insulin resistance, because when its levels increase, ET-1 can cause a condition of hyperinsulinemia. ET-1 was found to be high in patients with cardiovascular disorders, as well as in obese and diabetic subjects. Alternative methods for assessing endothelial function by measurement of biomarkers of activation and endothelial dysfunction such as soluble intercellular adhesion molecule-1 (sICAM-1). Levels of sICAM-1 have been found to be related positively to age, systolic and diastolic blood pressure, hypercholesterolemia, hypertriglyceridemia and inversely to estrogen. Furthermore, associations have been found between sICAM-1 and cardiovascular mortality in both healthy individuals and populations at high risk. The aim of the study was to evaluate FMD, concentrations of ET-1 and sICAM-1 in adolescents with a presence of obesity and hypertension and to compare these with controls (obesity and non hypertension), as well as to analyze the correlations between FMD, ET-1, sICAM-1 and blood pressure values.
This study was a single-blinded, two-armed, randomized controlled trial comparing a medication self-management intervention to usual care for hypertensive elderly in the residential care facility. To explore the effect of stage-matched tailored education on disease management for hypertensive elderly. Patient were randomly assigned to either a 6-month trans-theoretical model-based medication management intervention group or a treatment-as-usual group. we would like to improve its adherence to the medicine prescribed by their own physician through five sessions of face-to-face interview which focused on anti-hypertensive medication-related information, the importance of medication refills, motivation, self-management and self-check skills.
Exploring the safety, tolerability, and pharmacokinetic (PK) characteristics of oral TPN171H tablets in patients with Pulmonary Arterial Hypertension under continuous multiple administration conditions, providing a basis for determining the administration plan and recommended dosage in phase II clinical study.
Group A will be training group and group B will be control group. Deep breathing exercises will be done as baseline treatment in both groups. Both groups will be assessed with Modified Borg scale, 6-PBRT and Fatigue severity scale at the baseline. The control group patients will perform functional active alternating movements for the upper limbs at home involving three sets with 10 repetitions and a rest interval between 1- and 2-minute. Intervention will be for 3 times a week or 6 weeks. The treatment group patients will perform upper extremity aerobic exercises by using an arm ergometer under the supervision of a physiotherapist. Training intensity will adjust according to 50 80 % of max HR or intensity of dyspnea to 4 points on modified Borg scale (MBS) for at least 15 45 min, 3 times/week over 6 weeks.
To compare the effects of supervised endurance training versus home based exercise plan on functional capacity and fatigue among pulmonary arterial hypertension patients.
Clinical Trial to Evaluate the Efficacy and Safety of D064 and D702 Combination Therapy
Conversion of dietary nitrates to nitric oxide (NO) is a non-canonical pathway that plays an important role in NO biology, particulalry under pathological conditions. Nitrate supplementation has been shown to help control mild hypertension. Recent studies have suggested that another gaseous transmitter, hydrogen sulfide, also influences NO biosynthesis and metabolism. This open-label clinical trial will evalute the effect of Vascanox® HP, a proprietary formulation that combines dietary sources of nitric oxide and hydrogen sulfide, on nitric oxide bioavailability and on blood pressure in subjects experiencing elevated blood pressure. Participants will supplement with Vascanox® HP for four weeks. Blood pressure will be measured at baseline, two weeks, and fours weeks. Salivary nitric oxide will be assessed prior to and two, six, and 24 hours after dosing on the first day of the study and prior to and two hours after dosing at subsequent study visits. Participants will also self-monitor their saliva nitric oxide levels and blood pressure daily for 4 weeks. Changes in study outcomes over time will be evaluated via analysis of variance (ANOVA) and paired t-tests.
Causes' Fresh Produce Program (FPP) in Durham County has addressed barriers to food security related to transportation with an innovative delivery model, but lacks evidence regarding the impact of food supplementation on chronic diseases like hypertension, which is prevalent in historically excluded populations in Durham County. The goal of this research study is to determine the efficacy of the modified Dietary Approach to Stop Hypertension (DASH) diet in Black/African American and Hispanic/Latinx participants with chronic hypertension who identify as food insecure using a randomized controlled trial. This research will leverage FPP's innovative distribution system to deliver medically-tailored produce bags and provide education workshops to the experimental participants relative to their experimental group. The study population group intends to include members of the Durham community and surrounding areas that identify as members of either the Black/African American or Hispanic/Latinx populations. Success will be measured in pre- and post-intervention biomarkers and qualitative participant experience data. Recognizing the risk of using Protected Health Information of Durham community members, many of whom are members of historically excluded populations that have been subjugated to harmful and extractive research practices, steps will be taken to ensure that collected information about research participants' personal and health information is protected and used only for the purposes of research. Ultimately, this research aims to work directly with the community to address hypertension outside of the clinic using food and education delivered directly to participants. The success of such an intervention could lead to expansion of delivering medically and culturally tailored foods to the larger FPP population and beyond.
