This study tests a new approach for people who have had a heart valve replacement (TAVI) but do not need lifelong blood thinners. Instead of giving everyone aspirin for life, doctors will use a CT scan 3 months after the procedure to check for hidden blood clots on the new valve.…

This study looks at people who had gastric bypass surgery but later regained weight or didn't lose enough. It compares two different revision surgeries to see which works better for weight loss and has fewer side effects like diarrhea. About 150 adults will take part and be follo…

This study tests a new strategy for diagnosing prostate cancer in men with moderate risk. Instead of immediately doing a biopsy, doctors will monitor them with regular PSA tests and MRI scans. The goal is to see if this approach can safely delay biopsies, avoid unnecessary proced…

This study tests a new headband ultrasound device (SONAS) to see if it can detect right-to-left shunts—abnormal blood flow passages—in adults with hereditary hemorrhagic telangiectasia (HHT). About 40 participants will wear the device during their standard bubble echocardiogram, …

This study tests if listening to a short online hypnosis exercise every day for 6 weeks can improve self-esteem and resilience in children aged 10-11. Researchers will compare a group that starts right away with a group that starts later. They also hope to see if this practice ca…

This study tests whether freezing the nerves between the ribs (intercostal cryo-analgesia) can improve recovery and reduce pain after minimally invasive lung surgery. About 150 adults scheduled for lung surgery will either receive standard pain management or standard care plus th…

This study looks at hip fracture patients who take blood thinners (DOACs). Doctors often delay surgery to avoid bleeding, but waiting may cause other problems. The study compares operating within 24 hours versus waiting longer to see if early surgery increases the need for blood …

This study looks at why some replacement heart valves (TAVI) may wear out faster than others. Researchers will use special PET-CT scans to detect early signs of valve damage in 180 people who had TAVI about five years ago. They want to see if small blood clots on the valve or the…

This study aims to find out if certain substances in the blood can help predict serious complications after high-risk surgeries like heart, lung, or colon operations. Researchers will collect blood samples from about 5,000 patients before and after surgery and track their recover…
