This study tests a new, short course of highly focused radiation for men whose prostate cancer has returned after surgery to remove the prostate. The radiation is given in just 5 sessions, along with 6 months of hormone therapy. The goal is to see if this approach can control the…

This study compares a new leadless pacemaker (Micra AV) to a traditional pacemaker with wires in 100 adults aged 70 or older who need a pacemaker for a slow heartbeat. The goal is to see if the leadless version helps people exercise as well as the standard one. Participants are r…

This study tests if adding extra ablation to the standard procedure helps people with persistent atrial fibrillation (a type of irregular heartbeat) stay in normal rhythm longer. About 206 adults will get either standard ablation or standard plus additional ablation, using a newe…

This study compares two procedures to treat a common heart rhythm problem called paroxysmal atrial fibrillation (AFib). The standard method uses a freezing balloon, while the newer method uses electrical pulses. Researchers want to see if the new method is just as good at prevent…

This study looks at how a common heart valve procedure called TAVI changes the bacteria living in your gut. Researchers will collect blood and stool samples from 40 older adults before and three months after TAVI to measure bacterial byproducts and identify which bacteria are pre…

This study watches 120 adults having planned abdominal surgery to see how their gut bacteria change during the operation. Researchers collect samples like blood and tissue to check if these changes allow bacteria to move to other parts of the body and cause surgical site infectio…

This study looks at whether adults aged 70 and older with multiple health conditions, but no history of heart disease, can safely stop taking statins. Researchers are comparing those who continue statins to those who stop, tracking deaths and major heart events over two years. Th…

This study looks at whether bacteria from the gut can travel to other parts of the body during abdominal surgery and cause wound infections. About 209 adults having planned abdominal surgery will provide skin, gut, blood, and tissue samples. Researchers will use genetic sequencin…

This study tests a simple computer alert that reminds doctors to check if antibiotics are still needed after 72 hours. The goal is to reduce unnecessary antibiotic use and improve patient safety. About 58 hospital wards will take part, and the alert will be rolled out step by ste…

This study looks at how blood supply to the urethra relates to bladder pressure in people with and without stress urinary incontinence (leakage when coughing or sneezing). Researchers will use advanced ultrasound imaging to measure blood flow and compare it to standard pressure t…

This study compares how well doctors can measure tissue firmness using their hands (palpation) versus ultrasound. About 40 medical professionals and students will test these methods on artificial models. The goal is to see which method is more accurate and reliable, and whether p…

This study is collecting samples from over 1,200 surgery patients to see if changes in the body's chemistry can predict surgical site infections. The goal is to find early warning signs that could help personalize care. No treatment is being tested—only observation and analysis.…

This study looks at 4,500 people with pacemakers or similar heart devices to find out who is most likely to develop a condition where the heart weakens over time. Researchers will use routine medical and device data to create a risk score that helps doctors choose the best pacing…

This study tests two different emergency techniques to help infants who cannot be intubated or oxygenated. Doctors will practice on a realistic rabbit model to see which method is faster and safer. The goal is to find the best approach for this rare but life-threatening situation…
