This study compares two surgical methods—hysteroscopy and suction curettage—for treating early pregnancy loss in women who conceived through IVF. The goal is to see which method causes fewer uterine scars (adhesions) and leads to better future fertility. Fifty participants will b…

This study tests whether applying tranexamic acid (TXA) directly to the colon during polyp removal can reduce bleeding during and after the procedure. About 200 adults having large polyps removed will be enrolled. TXA is a drug that helps blood clot and is already used in other s…

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

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

This study explores whether hyperbaric oxygen therapy (HBOT) can help men with low sperm count (oligospermia) improve their fertility. Researchers will measure changes in sperm count, shape, and movement in 15 participants. The goal is to see if HBOT offers a new, non-drug option…

This study tests whether breathing pure oxygen in a pressurized chamber (hyperbaric oxygen therapy) can reduce depression in people who have had a stroke. Researchers will compare the treatment to a sham (fake) procedure in 142 adults aged 50-85 who have been depressed for at lea…

This study looks at whether a single session of hyperbaric oxygen therapy (breathing pure oxygen in a pressurized chamber) can increase muscle strength in healthy, physically active adults aged 18 to 45. Participants will do a mid-thigh pull test after either the real oxygen trea…

This study looks at how two different ways of measuring brain activity—EEG (which records electrical signals) and MRI (which tracks blood flow)—are related. Researchers will compare these patterns in 1,500 adults who have already had a brain MRI. The goal is to better understand …

This study will measure how hyperbaric oxygen therapy (HBOT) changes the number of stem cells in the blood of 60 adults aged 20 to 80 who are already scheduled to receive HBOT for other medical reasons. Researchers will take blood samples at different times during treatment to co…

This study follows 100 adults who had a traumatic brain injury and completed 60 sessions of hyperbaric oxygen therapy. Researchers will test their thinking, memory, and quality of life 1 to 4 years later to see if improvements stick. The goal is to understand the long-term effect…

This study compares two techniques—intermittent hypoxic training (simulating high altitude) and hyperbaric oxygen therapy (breathing pure oxygen in a pressurized chamber)—to see which better improves aerobic performance in healthy athletes. About 66 active athletes aged 18-45 wil…

This study looks for natural toxins called mycotoxins in breastmilk. These toxins come from fungi that can grow on stored grains and nuts. Researchers want to see if these toxins affect a baby's growth and development in the first months of life. About 150 mothers and their babie…
