This study compares two ways to treat long, diffuse blockages in heart arteries. One method uses a temporary scaffold and drug-coated balloons that leave no permanent metal behind. The other uses standard metal stents. Researchers will check how well blood flow improves right aft…

This study tests whether hyperbaric oxygen therapy (HBOT) can help transplanted fat survive longer in breast reconstruction after radiation treatment. Sixteen women who had radiation for breast cancer will each receive two fat grafting sessions—one with HBOT and one without—in a …

This study tests a precise, high-dose radiation technique called SBRT as an alternative to surgery for breast cancer in patients over 70 who are too frail for an operation. The goal is to find the safest highest dose that can be given in one to five sessions. If it works, it coul…

This trial tests a procedure called middle meningeal artery (MMA) embolization for people with chronic subdural hematomas—a buildup of blood on the brain that can cause confusion and weakness. The study will see if blocking the artery that feeds the hematoma can prevent it from r…

This study evaluates a same-day cervical cancer screening approach for women in Cameroon. Participants first collect their own sample for HPV testing, and if positive, they receive a digital cytology exam on the same day to determine if further treatment is needed. The goal is to…

This study looks at whether a newer type of brain scan (Tau-PET) helps doctors diagnose Alzheimer's disease more accurately than the standard scan (Amyloid-PET). About 120 adults aged 50-85 with mild memory or thinking problems will get both scans. Researchers will track how ofte…

This study tests whether three 15-minute hypnosis sessions can help people with persistent breathlessness from cancer, COPD, interstitial lung disease, or chronic heart failure feel more in control of their breathing. Researchers will measure changes using a standard questionnair…

This study looks at whether a smartphone app with daily mindfulness exercises can help reduce anxiety and improve quality of life for women undergoing IVF. About 150 women will either use the app for 15 minutes a day or receive standard care. Researchers will measure anxiety, dep…

This study tests two techniques to help people with insomnia: mental imagery (turning negative thoughts into positive ones) and using a scent during sleep to strengthen that positive feeling. 120 adults aged 18-45 with insomnia will be split into four groups to compare these meth…

This study tests if eating only during an 8-hour window each day (16-hour fast) helps menopausal women lose weight and reduce menopause symptoms. It includes women going through natural menopause or those with hormone-sensitive breast cancer. 84 participants will be randomly assi…

This study looks at whether a substance in the blood called 1,5-anhydroglucitol can help measure how many insulin-making cells (beta cells) children with type 1 diabetes still have. Researchers will compare levels in 60 children with diabetes (newly diagnosed and long-term) to he…

This study follows 163 teens and young adults with heavy menstrual bleeding, some with a bleeding disorder and some without, to see how well hormonal treatments like the pill, patch, or IUD work. Researchers will measure blood loss, quality of life, and iron levels over time. The…

This study looks at whether the amount of lean (fat-free) body mass before surgery can predict how much weight people lose in the two years after Roux-en-Y gastric bypass. Researchers will follow 91 adults with severe obesity who are scheduled for the procedure, measuring body co…

This study looks at whether Ryeqo, a newer hormone treatment for uterine fibroids and endometriosis, increases the risk of dangerous blood clots. Researchers will take blood samples from 30 women before they start Ryeqo and again after 3 months of treatment. The goal is to measur…

This study aims to find specific biological patterns in people who bleed easily for unknown reasons. Researchers will measure blood clotting, clot breakdown, and clot structure in 400 participants. The goal is to better understand the condition, not to test a new treatment.

This study looks at how long people with type 2 diabetes need to stop taking GLP-1 medications (like semaglutide) before surgery to make sure their stomach is empty. These drugs slow down digestion, which can increase the risk of food or liquid entering the lungs during anesthesi…

This study looks at brain activity in 30 people with Parkinson's disease who have deep brain stimulation (DBS) implants. Researchers want to understand the brain signals behind motor and mood changes that happen when medication wears off. By recording brain waves and stimulation …

This study is creating a large database of information from 20,000 people with brain aneurysms. Researchers will look at genetic, environmental, and other factors to better understand what causes aneurysms and how different treatments affect outcomes. Participants are not given a…

This study uses brain scans (fMRI) to see if people with cancer, COPD, or heart failure have different brain activity patterns when they feel breathless. It also tests whether immersive virtual reality can help ease that breathlessness. Only 16 participants are being recruited to…

This study tests a simple decision aid that helps teens and young adults (ages 12-25) make clearer choices about menstrual management and contraception. Participants will either use the decision aid or receive standard counseling. The goal is to see if the tool reduces confusion …
