GhentAges 18 years+ - NCT04256798RecruitingPhase 3
Respiratory care after high-risk abdominal surgery
This trial looks at a breathing-focused care plan given around the time of major abdominal surgery to improve recovery and outcomes. You may be eligible if you’re having a large midline abdominal incision and can be followed after surgery.
Botucatu, São PauloAges 10–100 - NCT04446832Recruiting
Vaccine study for people waiting for liver transplant
This study tests a vaccine strategy for people who are being evaluated and waiting for a liver transplant. The goal is to see how well the immune system responds and how the results are interpreted before transplant.
LyonAges 18 years+ - NCT04498598Recruiting
Test a modified breathing device for the voice box area
This study tests a modified supraglottic airway device (a type of breathing aid placed above the vocal cords) during surgeries done under general anesthesia. It may help researchers see if a better-shaped device works more safely during planned surgeries that use muscle relaxation.
Cleveland, OhioAges 18–100 - NCT04721041Recruiting
Fecal microbiota transplant for gut side effects after cancer treatment
This trial tests a treatment called “washed microbiota transplant,” which transfers healthy gut bacteria to help relieve intestinal problems that started after cancer therapy. You might benefit if you’re an adult with certain ongoing stomach or bowel symptoms after standard cancer treatment, and your body is stable enough for the procedure.
Nanjing, JiangsuAges 18 years+ - NCT04725916Recruiting
Study of water exposure and drain-related risks after certain surgeries
This trial looks at how using water (like showers) affects risks related to surgical drains after specific cosmetic or reconstructive procedures. Your results may help improve post-surgery safety guidance for patients who go home with drains.
Danville, PennsylvaniaAges 18 years+ - NCT04824066Recruiting
Using wearables to spot complications early
This study checks whether common wearable devices can predict or detect problems after treatment or surgery. If you join, the researchers will compare what the wearable shows with what happens to you medically, to see if earlier warnings are possible.
Boston, MassachusettsAges 18 years+ - NCT05114096RecruitingPhase 4
One-time steroid shot to help babies stay healthier early
This trial studies whether giving a single steroid medicine shot during pregnancy can improve outcomes when preterm birth is at risk. The goal is to help the baby’s lungs and overall health before early delivery.
