Hypertension (HTN) rates have increased worldwide, but the most significant increase in the incidence of morbidity and mortality has been in African Americans (AA) (43% vs 27% for other U.S. population groups). Despite evidence of positive benefits from lifestyle modification (healthy diet, reduced sodium intake, increased physical activity, smoking cessation) and prescribed antihypertensive therapy (AHT) many AA with HTN do not adhere to their treatment regimens. Consistent, effective lifelong self-management is required to sustain optimal BP control and thus reduce morbidity and mortality. Self-managing HTN to a blood pressure (BP) \<130/80 mm Hg presents challenges such as juggling multiple medications and health care providers, dealing with complex recommendations and treatment regimens, and coping with negative emotional states. Few studies have examined the biopsychosocial mechanisms that foster effective HTN self-management and resilience among AA living with HTN. Understanding the mechanisms that influence HTN self-management and resilience in AA holds the promise of new modifiable targets for behavior-change interventions. This study explores the relationship among resilience precursors on hypertension (HTN) self-management behaviors, stress response, and the effects that these relationships have on health outcomes-health-related quality of life (HRQOL) and blood pressure (BP) in African Americans (AA) with HTN over a 6-month period.

Background: \- Noncirrhotic Portal Hypertension (NCPH) is caused by liver diseases that increase pressure in the blood vessels of the liver. It seems to start slowly and not have many warning signs. Many people may not even know that they have a liver disease. There are no specific treatments for NCPH. Objectives: \- To learn more about how NCPH develops over time. Eligibility: \- People age 12 and older who have NCPH or are at risk for getting it. In the past year, they cannot have had other types of liver disease that typically result in cirrhosis, liver cancer, or active substance abuse. Design: * Participants will have 2 screening visits. * Visit 1: to see if they have or may develop NCPH. * Medical history * Physical exam * Urine and stool studies * Abdominal ultrasound * Fibroscan. Sound waves measure liver stiffness. \<TAB\>- Visit 2: * Blood tests * Abdominal MRI * Echocardiogram * Questionnaire * Liver blood vessel pressure (hepatic venous portal gradient (HVPG)) measurement. This is done with a small tube inserted in a neck vein. * They may have a liver biopsy. * All participants will visit the clinic every 6 months for a history, physical exam, and blood tests. They will also repeat some of the screening tests yearly. * Participants with NCPH will also have: * Upper endoscopy test. A tube inserted in the mouth goes through the esophagus and stomach. * At least every 2 years: Esophagogastroduodenoscopy. * At least every 4 years: testing including HVPG measurements and liver biopsy. * Participants without NCPH will also have: * Liver biopsy and HVPG measurements to see if they have NCPH. * Every 2 years: abdominal MRI and stool studies. * The study will last indefinitely.
NCT07365332
This is an adaptive, 2-part, randomized, multicenter, double-blind, placebo-controlled, parallel-group study designed to evaluate the efficacy and safety of IKT-001 in adult participants with WHO Group 1 PAH.
NCT07218029
Researchers are looking for more ways to treat PAH. In PAH, the blood vessels in the lungs become thick and narrow, which makes it harder for blood to flow. This causes high blood pressure in the lungs and overworks the heart. PAH can make it hard to breathe and be active. Some standard (usual) treatments for PAH can treat symptoms of PAH but do not stop PAH from getting worse. Sotatercept is a study medicine designed to treat PAH. It is a targeted therapy, which is a treatment that works on certain proteins that play a role in causing PAH. This is a long-term follow-up (LTFU) study. People who took part in certain other studies testing sotatercept for PAH may be able to join this study. The goal of this study is to learn about the long-term safety of sotatercept and if people tolerate it when taken with standard PAH treatment over a longer period of time.

NCT07272486
This study aims to evaluate whether virtual reality (VR) and classical music therapy, when added to standard antihypertensive treatment, can improve blood pressure control and reduce anxiety in patients presenting to the emergency department with hypertensive urgency. Patients with primary hypertension and no signs of end-organ damage will be randomly assigned to receive either standard treatment alone or standard treatment combined with VR and classical music. Blood pressure will be monitored at multiple time points over a 120-minute period, and anxiety will be assessed using the State Anxiety Inventory (STAI-I). The study seeks to determine if these non-pharmacological interventions can enhance the effectiveness of routine management of hypertensive urgency.
NCT07548567
This is a prospective, randomized, double-blind controlled trial evaluating an ultrasound-guided femoral artery block (FAB) using a long-axis in-plane approach compared with a short-axis approach and a control group. The study will include adult patients (ASA I-III) undergoing below-the-knee fracture surgery with tourniquet application. All patients will receive standardized anesthesia including sciatic nerve block and total intravenous anesthesia. Participants will be randomized into three groups: short-axis FAB, long-axis FAB, or control (saline injection). The primary aim is to assess the effectiveness of the long-axis FAB in reducing tourniquet-induced hypertension. Secondary outcomes include hemodynamic stability, analgesic requirements, pain scores, block characteristics, and procedural performance metrics.

NCT06252376
The goal of clinical trial is to learn about how blood pressure fluctuations affect cognitive performance (thinking abilities) and brain blood flow in persons with Parkinson's disease with and without orthostatic hypotension (low blood pressure when standing). The main questions it aims to answer are: * Is there a certain level of blood pressure that correlates with change in cognitive performance while upright? * Is there a certain level of change in brain blood flow that correlates with change in cognitive performance when upright? * How does cognitive performance differ between persons with Parkinson's disease that have orthostatic hypotension and those without orthostatic hypotension? * How does cognitive performance differ between the supine (laying down) and upright positions? * How do blood pressure and brain blood predict changes in cognitive performance over two years? Participants in this study will undergo the following procedures: * Complete a screening visit with questionnaires, medical history, physical exam, and head-up tilt-table test. * Attend one baseline study visit, during which they will undergo a battery of computerized cognitive tests repeated twice: once while laying down and once while upright on a tilt table. Simultaneously, during the experiments we will measure blood pressure using a wrist-worn device and inflatable arm cuff and will measure brain blood flow using functional near-infrared spectroscopy (fNIRS), a non-invasive device that uses light sensors to detect changes in brain blood flow. * Attend one two-year follow-up visit, during which they will repeat a battery of computerized cognitive tests repeated twice: once while laying down and once while upright on a tilt table. During this visit, like before, we will measure blood pressure using a wrist-worn device and inflatable arm cuff and will measure brain blood flow using functional near-infrared spectroscopy (fNIRS). Researchers will compare participants with Parkinson's disease with and without orthostatic hypotension in the laying down and upright positions to see if there are changes in thinking abilities between these groups.
NCT05144737
A pilot study titled "A Virtual Cardiometabolic Health Program for African Immigrants (The Afro-DPP Program) will be conducted to address the cardiometabolic of community-dwelling African immigrants who have multiple cardiometabolic risk factors including hypertension, Type 2 Diabetes, high cholesterol, and overweight/obesity. The proposed study will recruit a total of 60 participants and will use a non-equivalent control group design to test the effectiveness of the intervention at two African churches in the Baltimore, Washington, D.C. area. The two churches will be randomly assigned to the intervention or delayed intervention group. At the end of a 6-month follow-up period, the control church will receive the intervention (delayed control group). All participants will receive a Bluetooth-enabled digital scale (Omron Model: BCM-500) that measures body composition including Body Weight, Body Fat percentage, Visceral Fat, Skeletal Muscle percentage, Resting Metabolism and Body Mass Index. A Bluetooth-enabled blood pressure monitor (Omron Model: BP7250) will also be distributed to all participants. All participants will download the Omron Connect app which will allow the participants to sync participants' blood pressure readings and body composition readings into the app. The research team will access these readings to monitor study outcomes and participants progress during the follow-up period.
NCT06647511
The goal of this observational study is to use digital health tracking to improve how high blood pressure and other health issues are detected in pregnant refugee women. The main questions this study aims to answer are are: * Can a digital monitoring system that checks for high blood pressure in these women be tested and refined, using clinical training and validation? * Can this digital monitoring system accurately track any related pregnancy health issues and be used to refer participants to care providers? * Can this system be used to accurately identify risks associated with the contraction of pregnancy-related conditions, such as preeclampsia and high blood pressure? Participants will: * Complete baseline and follow-up in-person appointments; * Complete surveys at these appointment that track their health, stress levels, and comorbidities/risks associated with pregnancy; * Be given a smartwatch fitness tracker and electronic blood pressure cuffs for at-home measurements.
NCT07544836
This multi-site randomized controlled trial uses a community-based approach to evaluate a Food as Medicine program for Native Hawaiian and Pacific Islander (NHPI) adults in Hawaii who have high blood pressure and difficulty affording healthy food. The study has two main goals: (1) to implement a produce prescription program and see if adding personal support from Community Health Workers (CHW) improves blood pressure among other health outcomes, and (2) to determine the program's cost-effectiveness. The study will take place across three Federally Qualified Health Centers in Hawaii. Produce prescription program participants at each site will receive $100 per month, either in the form of produce boxes or monthly vouchers to purchase fruits and vegetables, for 12 months (totaling $1200). In past studies, personal challenges (e.g., lack of transportation, lack of cooking skills) have made it difficult for participants to use the vouchers and/or the purchased produce. In other food as medicine interventions, participants have similarly faced various personal, social, and environmental barriers that limit the program's efficacy. To help participants navigate through these challenges, the investigators want to test adding 1-on-1 support from a CHW throughout the program. Other studies have found that health interventions delivered by CHWs have been effective in reducing blood pressure, blood glucose and weight, especially among vulnerable populations, such as NHPIs and those with food insecurity. The CHWs in this study will receive a training using a curriculum tailored specifically to their community and that is in alignment with the Pilinahā: The Four Connections Framework, which focuses on key connections that Indigenous people seek to attain health and can be employed to overcome health disparities. To test the effectiveness of the added CHW support, there will be two groups of participants: Group 1 (Intervention) will receive the monthly produce prescription ($100 vouchers or produce box) plus meet with a CHW every two months for support with program challenges. Group 2 (Control) will receive the same monthly produce prescription, but will not have meetings with a CHW. The investigators want to see if the added support from CHWs leads to better blood pressure results, among other health outcomes. Upon providing informed consent and enrolling into the program, produce prescription program participants will: * Attend 5 study visits over the one year program. These happen at the start, and then at 3, 6, 9, and 12 months. * Complete health checks at the first visit. This includes getting a home blood pressure monitor and learning about heart health and nutrition. Staff will measure height, weight, waist size, and blood pressure. * Answer surveys about their demographic background, health habits, diet, and culture. * Receive $100 in vouchers every month for 12 months to redeem for fruits and vegetables at a local retailer. * Group 1 will additionally meet with a CHW every two months for 1-on-1 support with any challenges related to the program. * Group 2 will receive monthly reminders to use their vouchers but no CHW meetings. After the program ends, researchers will analyze the financial value of the intervention. This involves calculating the total cost to run the program (including vouchers, CHW training and salaries, and administrative costs) and comparing it to potential savings in healthcare costs. By looking at improvements in blood pressure, researchers can estimate how many heart-related health problems were prevented and how much money was saved on medical care.
NCT05746039
The goal of this clinical trial is to learn whether semaglutide, an FDA-approved treatment for diabetes and obesity, is feasible and tolerable in patients with advanced lung disease. The main question\[s\] it aims to answer are: 1. Are patients with advanced lung disease able to tolerate semaglutide therapy? 2. Are we able to titrate semaglutide therapy to a target weight? Participants will be asked to perform pulmonary function, physical function and body composition testing, as well as a blood draw before and after 12-weeks of semaglutide therapy. While on therapy, subjects will be surveyed regarding any adverse events or side effects.
NCT07439939
Portal vein thrombosis is defined as non-tumoural obstruction of the portal vein or one of its branches. Its incidence is 0.7 to 2.7 per 100,000 patient-years in the general population, and 4.6 per 100 patient-years in patients with cirrhosis. Histological modificaitions fo the portal vein wall and haemostatic changes have been described in cirrhotic patients. The contribution of these changes, both systemic and local, to the development of portal vein thrombosis is debated. One of the hypotheses put forward on the genesis of portal vein thrombosis is as follows: certain bacterial translocations from the digestive tract, promoted by portal hypertension, contribute to endothelial activation resulting in the release of von Willebrand factor and factor VIII, as well as platelet activation and the coagulation cascade, which is dysregulated by cirrhosis and underlying changes in haemostatic balance. Inflammatory phenomena and NETosis may also be involved. Studies suggest that cirrhotic patients have lesions of the glycocalyx located in the portal area, which may be involved in the development of portal vein thrombosis. Patients with cirrhosis may benefit from the placement of a transjugular intrahepatic portosystemic shunt (TIPS). During the TIPS placement procedure, blood is drawn from the internal jugular vein and the portal vein, allowing for parallel biological analyses. The assumption of this study is that haemostasis and inflammation are disrupted differently at the systemic and portal levels in cirrhotic patients.
