Comparing blood thinners to prevent clots after weight-loss surgery
This study compares two blood-thinning medications, rivaroxaban (a pill) and enoxaparin (a shot), to prevent dangerous blood clots after weight-loss surgery. If you are scheduled for bariatric surgery, this trial could help determine which approach works better for someone like you.

Does head-down position after surgery reduce chronic subdural hematoma recurrence?
This study tests whether placing patients in a head-down position (Trendelenburg) after surgery for a chronic subdural hematoma reduces the chance of the hematoma coming back. It may help people who are already scheduled for surgery to drain the blood collection.
Medellín, AntioquiaAges 18 years+ - NCT06938633Recruiting

This study uses a urine test to see if patients with high blood pressure are taking their medications correctly. The goal is to help you and your doctor improve your blood pressure control.
SingaporeAges 21–80 - NCT06938243RecruitingPhase 1
Vagus Nerve Stimulation for Early Stroke Arm Recovery
This trial tests whether a device called a vagus nerve stimulator (VNS), placed under the skin, is safe and helps improve arm function when started 3 months after a stroke. It is for people with moderate to severe arm weakness who can still move their arm a little.
Jinan, ShandongAges 30–75 - NCT07201363Recruiting
Inflammation and scarring markers after TAVI
This study looks at markers of inflammation and scarring in people who develop heart rhythm problems after having a TAVI procedure (a minimally invasive valve replacement). It may help doctors understand and predict these complications.
Rijeka, CroatiaAges 18 years+ - NCT07196020Recruiting
