NCT07550790
The K-PROSE study is a randomized clinical investigation evaluating strategies to prevent contrast-induced acute kidney injury (CI-AKI) in patients hospitalized with acute heart failure and moderate renal dysfunction (eGFR 30-75 mL/min/1.73 m²). Patients requiring contrast-enhanced CT imaging are randomized to either standard intravenous saline hydration or a furosemide-based decongestion strategy. Renal function is assessed using serial measurements of creatinine and cystatin C, before and after contrast exposure. By comparing renal outcomes, congestion status, and safety profiles, this study aims to determine whether a decongestion-focused approach provides superior renal protection compared with conventional hydration in high-risk acute heart failure patients.
NCT05398783
Background: Scientists have long used simple measures (such as height and weight) to estimate how much a person s body uses food (calories) as energy, as commonly called the metabolic rate. But metabolism varies among people with similar body sizes. Scientists now believe the old formulas for estimating metabolic rates may not work well for all people. Researchers want to find more accurate ways to measure a person s metabolism. Objective: This natural history study will examine the relationships between metabolism, body composition, and body surface area in a wide range of people. Eligibility: Healthy children and adults aged 2 years or older. Also, people aged 2 years or older with conditions that may alter metabolism. These may include diabetes, obesity, renal disease, or cancer. Design: Participants will spend 2 days and 1 night in the hospital. They will provide a medical history and answer questions about their activity levels, the foods they eat, and their lifestyle. They will also eat a special diet. Participants will undergo many tests: They will lie in a bed with a clear hood covering their head for 30 to 45 minutes to measure the gases in their breath. They will lie on a padded table for about 15 minutes while their body is scanned. They will stand on a platform while a 3D scanner measures their body. They will have a test to measure how fast an electric signal moves through their body. They will grip an instrument to measure the strength of their hands. They will drink salty water and provide blood and urine samples. Participants may be invited to return for these 2-day visits up to 8 times per year. Return visits must be at least 2 weeks apart.
