Houston, TexasAges Any age - NCT05114876Recruiting
Tested a new plan to support older adults after surgery
This study looks at a redesigned surgical care plan to better support older adults who may have memory or thinking changes after major planned surgery. If you qualify, you would be assessed before surgery and followed after to see whether this approach helps.
Toronto, OntarioAges 60 years+ - NCT05119868Recruiting
Mediterranean diet in pregnancy to prevent baby allergies
This trial studies whether following a Mediterranean-style eating pattern during pregnancy can lower the chance that a child develops allergies. It may help families who already have a higher allergy risk, by changing diet during early pregnancy.
NaplesAges 20–35 - 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 - NCT05127980Recruiting
Study of immune antibodies after first-time EBV infection
This study looks at how the immune system’s antibodies behave after a first-time EBV infection, including whether they mistakenly react with the body’s own tissues. You might be offered a chance to help doctors understand why some people get longer or more intense symptoms from infectious mononucleosis.
BaselAges 18 years+ - NCT05146336Recruiting
CytoSorb registry for critically ill patients needing blood treatment
This registry collects information about critically ill patients who receive the CytoSorb 300 mL blood treatment. It may help doctors better understand when the treatment works best and when it should not be used.
KlagenfurtAges Any age - NCT05153694Recruiting
Study of infections after bladder removal
This observational study follows people after surgery to remove the bladder to learn how often infections happen and what they look like. It may help doctors better prevent and manage complications after this operation.
Munich, Outside U.S./CanadaAges Any age - NCT05155878Recruiting
Study of factors that predict outcomes for certain pancreas tumors
This study looks at what features of certain pancreas and nearby tumors or cysts might help predict outcomes. It uses existing medical records (and consent, if applicable) and may help doctors better estimate prognosis for patients in the future.
UmeåAges 18 years+ - NCT05163925Recruiting
Study of a heart-lung device for emergency life support
This trial looks at using a specific heart-lung support machine (the EUROSETS ECMOLIFE system) for adults who need urgent “extra” circulation support. It may help clinicians understand how well the device works in serious situations like shock, cardiac arrest, or after heart surgery.
ViennaAges 18 years+ - NCT05167994RecruitingPhase 2
Pre-surgery radiation plus an anti-cancer drug for soft tissue sarcoma
This Phase 2 trial tests whether giving radiation before surgery, along with anlotinib and penpulimab, can improve treatment for localized soft tissue sarcoma. It may help shrink or control the tumor before conservative surgery.
Beijing, Beijing MunicipalityAges 18 years+ - NCT05170633Recruiting
Warming treatment for very preterm babies after blood transfusion
This study looks at whether a specific “blood warming” approach can help very preterm babies keep their body temperature from getting too low (hypothermia). It’s intended to reduce temperature drops around the time they receive red blood cell transfusions.
Columbia, South CarolinaAges 6 months–7 months - NCT05182541Recruiting
Support program for anxious mothers expecting twin babies
This trial tests a psychological screening and nursing (support) approach for pregnant people carrying twins. It may help you if stress, depression, or anxiety symptoms are high, and you want extra support during routine prenatal care.
Shenyang, LiaoningAges 18–50 - NCT05190978Recruiting
Test mesh use for breast reconstruction above the muscle
This study tests whether using surgical mesh can be done safely and works well in breast reconstruction done right away, in front of the chest muscle (pre-pectoral) using tissue expanders. It may help improve how the reconstructed area holds up, but you’d need to meet specific surgical and health requirements.
Los Angeles, CaliforniaAges 22–75 - NCT05190653Recruiting
Support during stem cell or CAR T cancer treatment
This study tests whether starting palliative and supportive care early (alongside cancer treatment) can improve comfort and support for people having stem cell transplant or CAR T-cell therapy. It may also help family caregivers by offering support during a difficult treatment period.
Calgary, AlbertaAges 18 years+ - NCT05190718Recruiting
Pharyngeal electrical stimulation for swallowing trouble after brain injury
