This study compares two types of distal gastric bypass revision surgery for people who regained weight or didn't lose enough after their first gastric bypass. About 150 participants will be randomly assigned to one of two surgical techniques. Researchers will track weight loss an…

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 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 whether listening to short online hypnosis exercises every day for six weeks can improve self-esteem and resilience in healthy children aged 10-11. Researchers will compare two groups of about 345 kids from Dutch primary schools. If successful, the approach might…

This study tests a technique called intercostal cryo-analgesia (ICCA), which uses cold to temporarily freeze nerves in the chest wall during minimally invasive lung surgery. The goal is to see if adding ICCA to standard pain management helps patients recover faster, use fewer opi…

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…
