Atlanta, GeorgiaAges 18 years+ - NCT03901924Recruiting
Ventilator settings to protect the breathing muscle
This study looks at a specific way to control a breathing machine (ventilator) to help prevent weakness of the diaphragm, the main breathing muscle, in newly intubated adults. You might be considered if you are newly on a ventilator for less than 36 hours and certain other conditions are not present.
Chicago, IllinoisAges 18 years+ - NCT03948048Recruiting
ECMO timing study for children with hard-to-treat septic shock
This trial looks at whether and when a heart-lung machine called ECMO should be used in children whose septic shock is not responding to standard treatment. It may help doctors choose the best timing to improve survival and recovery in the PICU.
ShanghaiAges 4 weeks–18 years - NCT03403699Recruiting
Stem cell treatment for damaged eye blood vessels in diabetes
This study tests human iPSC–derived (lab-grown) cells aimed at repairing fragile, damaged blood vessels in diabetic retinopathy. It also involves eye exams and a small skin biopsy to support the research.
Birmingham, AlabamaAges 21–98 - NCT03819296RecruitingPhase 1
Fecal transplant to treat cancer immunotherapy bowel side effects
This early-phase study tests whether changing your gut bacteria with a fecal transplant can improve diarrhea or colitis caused by cancer immunotherapy. It may help people whose symptoms have not fully settled with standard treatments like steroids and other immune-blocking medicines.
Houston, TexasAges 18 years+ - NCT03561376RecruitingEarly Phase 1
Zinc ointment versus petroleum jelly after skin surgery
This early-phase trial compares zinc oxide ointment versus petroleum jelly to help healing and scar appearance after certain skin surgeries. You might be able to join if you are having a suitable, uninfected, non-scalp skin incision and can use the study ointment.
Pittsburgh, PA, PennsylvaniaAges 18 years+ - NCT03356132Recruiting
Breast implant safety and satisfaction follow-up study
This study looks at side effects and satisfaction after breast implant surgery. It may help by sharing what problems happen most and how satisfied people feel after getting a Silimed® textured or Silimed foam-coated implant.
Niterói, Rio de JaneiroAges 18 years+ - NCT03214354RecruitingPhase 2
Stem cell transplant for children with sickle cell and ABO mismatch
This trial studies a stem cell transplant approach for children with sickle cell disease, using a sibling donor whose blood type is not compatible. It aims to see if this transplant method can safely reduce serious sickle cell complications.
Calgary, AlbertaAges 1–19 - NCT03228875Recruiting
Boston birth study for mothers who deliver a single baby
