This study looks at whether giving an extra antibiotic during a heart valve procedure (TAVI) can lower the chance of serious infection or death within six months. About 2,000 adults in Denmark having TAVI will be randomly assigned to receive either the standard antibiotic or a st…

This study compares different standard methods for a heart procedure called ablation, used to treat atrial fibrillation (an irregular heartbeat). About 1,125 adults will take part, and each will receive the method that is standard at the time of their treatment. The goal is to se…

This study compares two settings for implantable cardioverter defibrillators (ICDs) to stop fast heart rhythms. About 3980 people with heart disease getting a new ICD will be assigned to one of two pacing patterns. The goal is to see which pattern stops the dangerous rhythm bette…

This study compares a newer pacing method (directly pacing the heart's natural electrical system) to the standard pacing method in 1100 people with heart failure and a specific heart block. The goal is to see if the new method reduces the chance of death or unplanned hospital vis…

This study looks at whether staying away from alcohol for six months after a common heart procedure (ablation) can lower the chance of atrial fibrillation (AF) coming back. About 414 adults who drink moderately or more will be split into two groups: one that stops drinking and on…

This study tests a new, radiation-free MRI method to diagnose chronic mesenteric ischemia, a condition where narrowed gut arteries cause pain after eating. Researchers will measure oxygen levels in the portal vein in 40 people—half with pain, half without—to see if the scan can t…

This study tests a special scan (GSA SPECT/CT) to see if it can predict serious liver complications after surgery for liver tumors better than current tests. About 192 adults with liver tumors will get the scan before surgery, and doctors will track their recovery. The goal is to…

This study tests whether early, one-on-one physical therapy — including education and graded activity — helps people recover better after lumbar spinal fusion surgery. Researchers will track 12 adults with chronic low back pain to see if this approach improves their ability to re…

This study tests whether treating anemia with iron, vitamins, and medication can help people recover from a serious heart infection called infective endocarditis. About 74 adults with both the infection and anemia will receive either standard care or additional anemia treatment. …

This study looks at whether structured play and physical activity can help preschool children with cancer improve their motor skills and development. 82 children aged 1 to 5 will be split into two groups: one gets play sessions at the hospital, and the other gets those plus paren…

This study tests a stepped-care program to support relatives of people with serious brain diseases or injuries. 160 relatives will either receive the program or usual care. The goal is to reduce caregiver burden and improve well-being.

This study will follow 200 adults undergoing surgery for liver, esophagus, stomach, or pancreatic cancer. Researchers want to see how patients' pre-surgery expectations relate to their actual pain, recovery, and long-term outcomes. No new treatments are tested; the goal is to bet…

This study will look back at the medical records of 50 adult ICU patients with COVID-19 who needed a special life support machine (VV-ECMO). The goal is to understand how often these patients have serious bleeding or blood clots, and how blood transfusions and blood thinners affe…

This study will test the thinking skills of 175 children and young adults who had a bone marrow transplant in childhood. Researchers want to see if problems with memory, concentration, and learning are linked to other late effects like metabolic changes and low physical fitness. …

This study looks at whether stopping combined oral contraceptives (birth control pills) can change serotonin levels in the brain. Researchers will compare women who stop taking the pill with those who continue, using brain scans and memory tests. The goal is to understand if the …

This study will use a small heart monitor (implantable loop recorder) for up to three years to find hidden atrial fibrillation in 100 people with moderate-to-severe mitral valve regurgitation who have few or no symptoms. The goal is to learn how common these hidden heart rhythm p…

This study follows 100 children in Denmark who receive a stem cell transplant for serious blood diseases. Researchers will test their thinking, memory, and physical abilities before the transplant and for one year after. The goal is to learn which medical, physical, and environme…

This study looks at 20 adults with short bowel syndrome who rely on IV nutrition (parenteral support). Researchers want to see how the IV fluids change liver stiffness readings from a FibroScan, so doctors can know the best time to check the liver. The goal is to improve monitori…

This study looks at how doctors trust artificial intelligence (AI) when estimating a baby's weight during pregnancy. About 308 clinicians will review ultrasound cases and compare AI-based estimates with traditional methods. Some doctors will also see how certain the AI is about i…
