AngersAges 15 years+ - NCT02714387Recruiting
Study of serious complications from non-traumatic blood vessel brain problems
This study follows people who have non-injury (non-traumatic) blood-vessel-related problems in the brain to understand serious complications. It may help researchers identify risks and improve care over time.
AngersAges 15 years+ - NCT05586867Recruiting
Blood testing study in people on hemodialysis
This study looks at blood markers related to iron and other body processes (like minerals, liver function, and inflammation) in people receiving hemodialysis. The results may help doctors better understand what affects health in dialysis patients.
Quincy-sous-SénartAges 18 years+ - NCT03848962Recruiting
Share leftover or collected samples for research
This study helps collect and share human samples (like blood or other specimens) so researchers can do new studies. It’s mainly about providing samples for research use, not testing a treatment on you.
Huntsville, AlabamaAges 1 month–89 years - NCT05667519Recruiting
Ultrasound-guided pacemaker lead placement to prevent valve leak
This trial tests a way to place a pacemaker lead using a special ultrasound view through the esophagus (a transesophageal echocardiogram). The goal is to reduce the chance of developing a serious leak in the tricuspid valve caused by the pacemaker lead.
Munich, BavariaAges 18 years+ - NCT05689775Recruiting
Robot-assisted reconstruction using tummy muscle flap after surgery
This trial studies a specific way to rebuild the pelvic floor (and sometimes the vagina) after major rectal or anal cancer surgery. It uses robotic surgery and a flap taken from your tummy muscle to help close and reconstruct the area.
OsloAges 18 years+ - NCT05366452Recruiting
Early heart pump implant for shock after a heart attack
This trial studies whether putting in a small heart pump early (through the leg) helps people with a heart attack complicated by severe heart weakness (“cardiogenic shock”) compared with standard treatment. It aims to improve survival and recovery by supporting blood flow sooner.
Marseille, Bouche DU RhoneAges 18–80 - NCT05237063Recruiting
Predicting kidney stone recurrence and complications using precision medicine
This study looks for better ways to predict when kidney stones may come back and what complications might happen. It may help doctors personalize follow-up and prevention plans based on information collected from you.
AmiensAges 18 years+ - NCT04652180Recruiting
Robot surgery versus open surgery for esophagus cancer
This trial compares robot-assisted surgery with the standard open chest operation to remove esophagus and nearby tissue. It may help you understand which approach works better and is safer for patients whose cancer can be surgically removed.
L'Hospitalet de Llobregat, BarcelonaAges 18 years+ - NCT05755230Recruiting
Study of health results around surgery
This study follows people who are having surgery to see what happens before, during, and after the procedure. It may help doctors understand what factors are linked to better recovery.
Buenos AiresAges Any age - NCT05763446Recruiting
Predicting heavy blood transfusion during liver transplant
This study looks for factors that can predict when a person might need a very large blood transfusion during a liver transplant. The results may help the transplant team prepare sooner and better manage transfusions during surgery.
RomeAges 18 years+ - NCT05793203Recruiting
Tests noninvasive checks to spot liver transplant complications early
This study looks at how well noninvasive tests (tests that don’t require surgery or taking tissue) can detect complications after a liver transplant. It may help patients and teams find problems earlier using safer, easier monitoring.
RomeAges 18–75 - NCT05799898Recruiting
Fast heart and vessel check for people on immune cancer drugs
This trial looks at a faster heart and blood-vessel assessment for people who are taking immune cancer drugs and have been referred because they might be having a heart-related side effect. It may help by speeding up evaluation and treatment decisions when symptoms raise concern.
ParisAges 18 years+ - NCT05127252Recruiting
Study how gut bacteria may affect time to pregnancy
This study looks at whether differences in the gut (microbiome) are linked to how long it takes to get pregnant and pregnancy outcomes. It may help researchers understand who might benefit from future microbiome-focused approaches.
Stockholm, HuddingeAges 18–40 - NCT05698628Recruiting
Timing strategies to protect legs during peripheral ECMO
This trial studies whether an “early” or more “conservative” approach to improving blood flow to the leg can prevent limb damage during a type of heart-lung machine called peripheral VA-ECMO. It may help reduce the risk of poor leg blood flow (ischemia) in people with severe heart failure-related shock.
SeoulAges 19 years+ - NCT05936515Recruiting
Training nurses and aides to shorten hospital stays
This study tests whether a new training program for nurses and nursing assistants can help elderly patients stay in the hospital for a shorter time and reduce avoidable hospital complications. You may be able to take part if you’re 75 or older and currently hospitalized on a participating hospital ward.
Bourg-en-BresseAges 75 years+ - NCT05936814Recruiting
Study measures knee alignment in severe varus osteoarthritis
