This study tests a special stent called PK Papyrus to repair holes (perforations) that can happen in heart arteries during procedures. About 41 people with such tears will receive the stent. The goal is to see how safe and effective it is at sealing the artery and preventing comp…

This study looks at 300 adults with low platelet counts who need a heart stent. It compares two common blood thinner combinations (aspirin plus clopidogrel vs. aspirin plus ticagrelor) to see which causes fewer bleeding problems. The goal is to find the safer option for these pat…

This study is tracking 50 adults with neuroendocrine tumors who are receiving peptide receptor radionuclide therapy (PRRT). Researchers are collecting data on patient characteristics, treatment responses, survival, and side effects. The goal is to better understand who benefits f…

This study is looking at whether a blood test called the Enhanced Liver Fibrosis (ELF) test can find early signs of fatty liver disease in people who are at high risk, such as those with diabetes, high blood pressure, or heart disease. Researchers will review medical records of 3…

This study uses an anonymous survey to understand who teaches advanced gastrointestinal (GI) surgery to fourth- and fifth-year general surgery residents in the U.S. It also measures residents' comfort with common and complex GI procedures and their interest in a specialized GI fe…

This study will review medical records of 100 trauma patients with colon injuries treated at Methodist Dallas Medical Center. Researchers want to see which surgical approaches lead to the best outcomes. No new treatments are being tested; instead, the goal is to learn from past c…
