This trial tests whether a personalized, context-guided form of brain stimulation works better than the standard approach for adults with major depressive disorder. Participants receive either standard intermittent theta burst stimulation (iTBS) or a version where the stimulation…

This study investigates whether a special cooking oil called diacylglycerol (DAG) oil can improve thinking skills and reduce body weight in adults aged 45 to 75 who have both obesity and mild cognitive impairment. Participants replace their usual cooking oil with either regular r…

This phase 2 trial tests whether taking a probiotic supplement (OMNi-BiOTiC® SR-9) twice daily for 90 days can improve gut health and recovery in people aged 60 and older who have had an acute ischemic stroke. The study will compare the probiotic to a placebo in 220 participants,…

This study tests whether a device that temporarily restricts blood flow to the arms (remote ischemic conditioning) can help lower blood pressure in people with hypertension who moved to high-altitude areas. 184 adults will either continue their usual medication or add the device …

This study tests a device that temporarily stops blood flow to the arms in short cycles, aiming to help people with high altitude polycythemia — a condition where the body makes too many red blood cells at high altitudes. The trial will involve 222 adults living above 2,500 meter…

This study tests a simple, non-invasive treatment called remote ischemic conditioning (RIC) for people who have had a stroke and also developed heart muscle injury. RIC involves using a blood pressure cuff on the arm to briefly restrict blood flow, which may trigger the body's ow…

This study tests whether astaxanthin, a natural substance from algae, can slow brain aging in adults aged 50 and older. Over 6 months, 120 participants will take either a low or high dose of astaxanthin or a placebo. Researchers will measure changes in memory, thinking, brain sca…

This study tests whether a structured 8-week breathing exercise program can help patients who have been on a ventilator for at least 21 days to wean off more successfully. Researchers will measure diaphragm function and weaning success in 120 participants across multiple centers.…

This study explores whether a single MRI fat-fraction (MRI-FF) scan can accurately diagnose osteoporosis and sarcopenia (muscle loss) in people with chronic kidney disease (CKD). Researchers will compare MRI-FF results with standard DXA scans in 868 participants—half with CKD and…

This study aims to create an artificial intelligence system that can automatically analyze confocal microscopy images of the cornea to diagnose dry eye disease. Researchers will collect eye scans from 75 adults (healthy and with dry eye) to train and test the AI. The goal is to r…

This study tests whether a rapid PCR test done right in the clinic can help doctors diagnose and treat acute respiratory infections faster. Over 16,000 adults at risk of severe illness will take part. The goal is to see if this approach lowers rates of respiratory failure and hos…

This trial tests whether a 12-week structured exercise program, called "Exercise for Muscle Health," can improve muscle mass, strength, and physical function in breast cancer survivors who have sarcopenia—a condition of muscle loss and weakness. About 104 women who have finished …

This study looks at whether listening to music can help lower anxiety in adults who have been on a breathing machine for more than 21 days. Two hundred participants will either get standard care or also listen to calming music through headphones for 30 minutes, twice a day, for t…

This study is testing a smartphone-based system that gives personalized advice to breast cancer patients going through chemotherapy. The system uses a knowledge graph to combine medical guidelines and patient-reported symptoms. Thirty patients and their nurses will use the system…

This study tests whether short, controlled sessions of low-oxygen breathing (intermittent hypoxia) can improve sleep in people with primary insomnia. Thirty adults aged 18 to 60 who are not taking sleep medications will be randomly assigned to receive either the real low-oxygen t…

This study tests whether drinking oat milk every day for 4 weeks can improve bowel movements in adults with constipation. About 100 participants will either drink oat milk or continue their normal diet. Researchers will track changes in gut bacteria, symptoms, and stool frequency…

This study looks at whether a special genetic test (tNGS) can help doctors treat hospitalized adults with pneumonia that isn't responding to first antibiotics. About 524 participants will be randomly assigned to get the test or standard care. The main goal is to see if the test s…
