This study looks at a procedure called middle meningeal artery (MMA) embolization for people with chronic subdural hematomas—a type of brain bleed common in older adults. The goal is to see if blocking certain blood vessels can stop the bleed from coming back after surgery, or ev…

This study compares two ways to treat long, spread-out blockages in heart arteries. One method uses a dissolving scaffold and drug-coated balloons, while the other uses permanent metal stents. The goal is to see if the newer approach works as well at keeping arteries open after 1…

This study tests a precise, high-dose radiation technique called SBRT as an alternative to surgery for breast cancer in elderly or frail patients who cannot have or refuse surgery. The goal is to find the safest highest dose that can control the tumor. About 36 participants aged …

This study looks at whether hormonal medications (like birth control pills, patches, injections, or IUDs) work equally well for heavy menstrual bleeding in teens and young adults with a bleeding disorder compared to those without. About 163 participants under 26 will be followed …

This study aims to see if a newer type of brain scan (Tau-PET) can improve doctors' ability to diagnose Alzheimer's disease compared to a standard scan (Amyloid-PET). Researchers will enroll 120 adults aged 50-85 with mild memory or thinking problems. Participants will receive bo…

This study is testing a new way to screen for cervical cancer that can be done in one day. Women will first test themselves for HPV, and if positive, they will have a digital image of their cervix reviewed by a specialist remotely. The goal is to see if this approach is accurate …

This study tests whether hyperbaric oxygen therapy (HBOT) helps transplanted fat survive better in breast reconstruction after radiation. Sixteen women who had radiation for breast cancer will each receive two fat grafting sessions—one with HBOT and one without. MRI scans will me…

This study tests two techniques to help people with insomnia: mental imagery rescripting (turning negative thoughts into positive ones) and using a specific scent during sleep to strengthen those positive thoughts. 120 adults with insomnia will be split into four groups to compar…

This study tests whether time-restricted eating (eating only during an 8-hour window each day) can help menopausal women—including those treated for hormone-sensitive breast cancer—lose weight, reduce menopause symptoms, and improve overall health. 84 women will be randomly assig…

This study tests whether a smartphone app with daily mindfulness exercises can reduce anxiety in women undergoing in vitro fertilization (IVF). About 150 women will either use the app for 15 minutes each day during their treatment or receive standard care. Researchers will measur…

This study explores how the brain processes chronic breathlessness in people with advanced cancer, COPD, or heart failure. Researchers will use brain scans (fMRI) and virtual reality to see if different diseases cause different breathlessness patterns. The goal is to learn if cur…

This study aims to find specific biological patterns in people who bleed easily for unknown reasons. Researchers will analyze blood samples from 400 participants to understand the different mechanisms behind this condition. The goal is to better classify and eventually improve ca…

This study aims to find out if a person's lean body mass before gastric bypass surgery can help predict how much weight they will lose in the two years after the procedure. Researchers will follow 91 adults with severe obesity who are scheduled for or have already had the surgery…

This study looks at brain activity in 30 people with Parkinson's disease who have a brain pacemaker (deep brain stimulation). Researchers want to understand why symptoms like movement problems and mood changes can come and go. By recording brain signals during medication changes,…

This study tests a simple decision aid that helps teens and young adults (ages 12-25) make clearer choices about menstrual management and contraception. About 252 participants will use the tool during a doctor visit to see if it reduces uncertainty compared to standard counseling…

This study looks at how long people with type 2 diabetes should stop taking GLP-1 medications (like semaglutide) before surgery to ensure their stomach is empty. About 38 participants will have three stomach ultrasounds over a week after fasting. The goal is to find a safe waitin…

This study checks if a substance in the blood called 1,5-anhydroglucitol can help measure how many insulin-producing cells children with type 1 diabetes still have. Researchers will compare levels in newly diagnosed children, those with long-term diabetes, and healthy volunteers.…

This study is creating a large database of information from 20,000 people with brain aneurysms. Researchers will collect genetic, imaging, and health data to find out what makes aneurysms form or rupture. The goal is to improve prediction and treatment, but participants do not re…

This study looks at whether Ryeqo, a new hormone treatment for uterine fibroids, increases the risk of dangerous blood clots. Researchers will measure blood clotting markers in 30 women before and after 3 months of taking the drug. The goal is to better understand the safety of t…
