This study tests whether applying tranexamic acid (TXA) directly to the colon during a colonoscopy can reduce bleeding when removing large polyps. About 200 adults who need polyp removal will take part. The goal is to see if this simple step makes the procedure safer.

This study compares two surgical treatments for early pregnancy loss (miscarriage) in women who became pregnant through IVF. One method is standard suction curettage, and the other uses a hysteroscope with a tissue removal device. The goal is to see which approach causes fewer ut…

This small pilot study is exploring whether hyperbaric oxygen therapy (HBOT) can help men with low sperm count (oligospermia), a common cause of infertility. Researchers will measure changes in sperm count, shape, and movement in 15 men before and after treatment. The goal is to …

This study tests if hyperbaric oxygen therapy (breathing pure oxygen in a pressurized chamber) can help people recover faster after anterior cruciate ligament (ACL) knee reconstruction. About 40 adults aged 18-45 who need ACL surgery will be randomly assigned to receive HBOT or s…

This study tests whether hyperbaric oxygen therapy (breathing pure oxygen in a pressurized chamber) can improve thinking, memory, and other lingering symptoms in people with long COVID. About 91 adults who have had cognitive problems for at least 3 months after a COVID infection …

This study looks at whether breathing pure oxygen in a pressurized chamber (hyperbaric oxygen therapy) can reduce depression in people who have had a stroke. The trial will include 142 adults aged 50-85 who have been depressed for at least 6 months after their stroke and are alre…

This study looks at how hyperbaric oxygen therapy (HBOT) changes the number of blood stem cells in adults aged 20 to 80 who are already receiving HBOT for other reasons. Researchers will take blood samples at different times to count stem cells using special markers. The goal is …

This study looks at two different training methods—intermittent hypoxic training (breathing low-oxygen air) and hyperbaric oxygen therapy (breathing high-pressure oxygen)—to see which one improves aerobic performance better. About 66 healthy athletes aged 18-45 who train at least…

This study looks for toxins from moldy grains and nuts in breastmilk. Researchers will test milk from 150 women and track their babies' development. The goal is to see if these toxins can affect infant health.

This study looks at people who had a traumatic brain injury and were treated with hyperbaric oxygen therapy (breathing pure oxygen in a pressurized chamber) 1 to 4 years ago. Researchers want to see if the improvements in thinking and memory from that treatment are still there. A…

This study aims to understand how two different ways of looking at the brain—MRI scans (which show blood flow) and EEG (which measures electrical activity)—are related. Researchers will compare these brain patterns in 1,500 adults who have already had an MRI. The goal is to impro…

This study looks at whether breathing air with extra oxygen can help healthy, active adults produce more muscle force during a pulling test. About 48 people aged 18-45 who exercise regularly will take part. Each person will be tested in both an oxygen-rich and a normal-air (sham)…
