Renal Pelvic Denervation Pilot Trial

The RPD Pilot trial will evaluate the safety and effectiveness of Verve Medical's RPDTM renal denervation system for hypertensive patients with uncontrolled blood pressure despite use of two medications at a therapeutic dose. The novelty of the RPDTM system relates to its placement via natural orifice into the renal pelvis (bilaterally) for delivery of radiofrequency energy to ablate the nerves that pass through the outer wall of the renal pelvis, a technique referred to as renal pelvic denervation (RPD).

Ultrasound With Subharmonic Imaging and Subharmonic Aided Pressure Estimation (SHAPE) to Identify Portal Hypertension

This clinical trial tests the how well an ultrasound with subharmonic imaging and the subharmonic aided pressure estimation (SHAPE) technique works in identifying portal hypertension (PH). An ultrasound takes pictures of the inside of the body by bouncing sound waves off organs. PH is high blood pressure in the vein that carries blood to the liver from the stomach, small and large intestines, spleen, pancreas, and gallbladder. The complications associated with PH are clear only after severe liver dysfunction or liver cirrhosis develops and are accompanied by relatively high mortality rates (20-70% mortality within 2 years). Thus, identifying PH earlier is beneficial. The hepatic venous pressure gradient (HVPG) obtained using an invasive catheterization procedure remains the standard for assessing PH. However, using this invasive procedure to assess PH prevents frequent pressure monitoring. Thus, a noninvasive technique to estimate PH is beneficial not only for diagnosis but also for monitoring treatment and disease progression. The SHAPE technique is a noninvasive ultrasound-based imaging technique that can estimate pressure with an ultrasound contrast agent. A noninvasive technique using an ultrasound with subharmonic imaging and the SHAPE technique may work in identifying PH.

Variability In Mixed Meal Tests: Fixed Versus Adjusted to Energy Needs Caloric Dose

Background: Researchers use mixed meal tolerance tests (MMTTs) to look at how people s bodies respond to eating a meal. However, researchers do not agree on how to decide the number of calories to give in each meal. Some use fixed meals, which are the same size for everyone, and some use adjusted meals, based on the size of the person s body. Researchers want to know which MMTT is best to use for future research. Objective: To learn how fixed vs adjusted meals affect blood glucose levels in healthy people. Eligibility: Healthy people aged 18 years or older. Design: Participants will have 3 or 4 clinic visits of up to 8 hours in 8 weeks. Participants will have baseline tests: Their height, weight, and waist size will be measured. They will have an oral glucose tolerance test: A needle attached to a tube (IV) will be inserted into a vein in the arm. They will have a sugary drink. Blood samples will be taken from the tube at intervals up to 3 hours after the drink. They will have a body scan. Participants will have 2 MMTT visits. One will include a fixed meal and one will include an adjusted meal. They will have tests at both visits: Resting metabolic rate: A clear hood will be placed over the participant s head while they rest for 20 minutes. This will measure the oxygen they breathe in and out. MMTT. Participants will have 5 minutes to drink a liquid meal. Blood samples will be taken at intervals for the next 4 hours....

The Effects of Increasing Caloric Intake on Diet-Induced Thermogenesis and 24h Energy Expenditure

Background: Diet-induced thermogenesis (DIT) is the amount of energy one's body uses to eat food, absorb the nutrients from the food, and process those nutrients. Researchers would like to understand more about how changing the balances of protein, fat, carbohydrates, and total calories in the diet can affect DIT. Objective: To learn how different diets can change a person's DIT. Eligibility: Healthy people aged 18 to 60 years who have not intentionally lost weight in the past 6 months. Design: Participants will stay in a clinic for about 35 days. They will eat only the food provided. They will receive 8 different diets during the study, including 7 test diets. Participants will undergo multiple tests. They will be screened with blood and urine tests and a test of their heart function. During the first few days: Their waist, thigh, and neck circumference will be measured. They will have a DXA scan: They will lie on a padded table for about 20 minutes while an instrument measures the amount of fat in their body. They will be tested for diabetes. They will answer questionnaires about topics including eating behavior, hunger, and stress. Throughout the study: Their weight will be measured daily. Blood tests will be repeated. They will stay in a metabolic chamber a total of 9 times. They will remain in a closed room for 24 hours while researchers monitor the room temperature and levels of oxygen and carbon dioxide. Participants will collect all their urine for each 24-hour period. ...

Redefining Evaluation of Adiposity and Leanness: Broadening Objective Diagnostics for Obesity

The purpose of this study is to evaluate body composition across a variety of medical, professional, and commercial devices, including: bioelectrical impedance analysis (BIA) devices, 3-dimensional optical imaging (3DO), manual anthropometry measurements, dual-energy X-ray absorptiometry (DXA), magnetic resonance imaging (MRI), and blood tests. The secondary study purpose is to compare body composition measurements from BIA devices, 3DO, and manual anthropometry measurements within a 1-week period for a subset of the study population. The study plans to enroll 300 healthy (having no life-threatening conditions or diseases; male and female) participants, 18 years of age or older.

Assessing the Impact of Perceptions of Unpredictability on Objective Measures of Food Consumption and Metabolism

Background: Many people in the United States are overweight or obese. This natural history study will look into how life events during childhood can impact eating behaviors and weight gain as adults. Objective: To explore how childhood experiences affect adult eating behaviors. Eligibility: Healthy people aged 18 to 60 years. Design: Participants will have 3 clinic visits. They will be screened with blood tests. They will answer questions about their alcohol and tobacco use. At the next visit, participants will undergo these activities: Parts of their body (such as waist, neck, and thighs) will be measured with a tape. They will have an imaging scan to find out how much body fat they have. They will start wearing a device like a wristwatch that measures their physical activity. They will wear this device for up to 10 days. They will wear a device on their upper arm or belly that measures blood glucose (sugar) levels. Participants will wear this for 7-10 days. They will answer questions about their education, childhood, and routines. They will receive a kit to collect a stool sample at home. At the last visit, participants will have these tests: Participants will relax and breathe normally while wearing a clear, plastic canopy that fits over their entire head. Blood samples will be taken before and after participants drink a sugary drink. Participants will be offered a large selection of foods for lunch. They will eat as much as they want. Then they will answer questions about how they feel about food and themselves.

Comparative Effectiveness of Carvedilol Versus Metoprolol Succinate in Heart Failure Patients With an Implantable Cardioverter Defibrillator

This prospective, multicenter, open-label, randomized comparative effectiveness trial, titled CARVTOP-ICD, evaluates the impact of carvedilol versus metoprolol succinate in patients with heart failure with reduced ejection fraction (HFrEF) and an implantable cardioverter defibrillator (ICD). The study will enroll 2,000 participants across 100 U.S. sites and includes an 18-month feasibility phase with 100 participants from 15 sites. Eligible participants must be currently treated with metoprolol succinate and willing to switch to carvedilol, with randomization in a 1:1 ratio. Participants will be followed for up to 3 years, with regular assessments including ICD interrogations, medication adherence, healthcare utilization, and quality of life surveys. The primary endpoint is the first occurrence of any ICD therapy (appropriate or inappropriate), cardiovascular (CV) hospitalization, or CV death. Secondary endpoints include ICD shock burden, healthcare utilization, and patient-reported quality of life. The trial aims to provide high-quality comparative data to address clinical equipoise surrounding the two commonly used beta-blockers in HFrEF management.
