Treating C-section scar defect with hormones versus surgery alone
This trial compares two treatments for a pregnancy-related problem in the uterus: vaginal repair alone versus vaginal repair plus leuprorelin (a hormone medicine). It aims to improve symptoms like long or heavy bleeding when a C-section scar defect is also linked with adenomyosis.
Shanghai, Shanghai MunicipalityAges 18–50 - NCT05483465RecruitingPhase 4
NAD supplement trial for brain blood vessel health in aging
This trial studies whether taking an NAD supplement can support brain blood vessel health as people age. Participants will be tested for brain and health changes and may help researchers understand how to keep the brain’s blood vessels healthier over time.
Oklahoma City, OklahomaAges 60–85 - NCT04397159Recruiting
Exercise program to reduce tiredness in some kidney patients
This trial studies whether doing a combination exercise program can reduce “fatigability,” meaning feeling unusually tired or weak during activity, in Veterans with moderate-to-advanced chronic kidney disease. It also compares results with people without kidney disease and checks for safety, especially for heart and joint health.
