Testing bacteria in children’s noses and ears
This study looks at bacteria (especially pneumococcus) in the nose and throat of children. It includes children with ear infections or healthy children, to understand which germs are carried and how they relate to illness.
CréteilAges 6 months–15 years - NCT06148025RecruitingPhase 4
Do antibiotics affect vaccine responses?
This study looks at whether taking a short course of antibiotics can change how your body responds to two vaccines (BCG and yellow fever). It may help researchers find ways to make vaccines work better.
Adelaide, South AustraliaAges 18–35 - NCT06268795Recruiting
Comparing biopsy vs. aspiration for shoulder/elbow revision surgery
This study compares two methods—biopsy (taking a small tissue sample) and aspiration (drawing fluid)—to see which one better detects infection in people having repeat shoulder or elbow replacement surgery. The results will help doctors choose the best test for future patients.
Wigan, LancashireAges 18 years+ - NCT07640581Recruiting
RSV Infection Study in Babies Under 2 Years
This study tracks how respiratory syncytial virus (RSV)—a common respiratory infection in babies—affects children under 24 months in Ho Chi Minh City. Researchers want to understand how often RSV happens, how severe it is, and how it impacts families, so they can better prepare healthcare services.
Ho Chi Minh City, Ho Chi MinhAges birth–2 years - NCT06379321Recruiting
Triathlon Hinge Knee System Study
This study looks at how well the Triathlon Hinge Knee system works for people who need a complex knee replacement. It helps your surgeon know if this implant is a good option for you.
Weston, FloridaAges Any age - NCT06447337Recruiting
Continuous body temperature monitoring trial
This trial tests a wearable device that continuously measures your body temperature while you are in the hospital. It may help doctors track fever or temperature changes caused by infections or other illnesses.
Belgrade, Other/Not ApplicableAges 18 years+ - NCT03225794Recruiting
Study of simian foamy virus spread to people in Cameroon
This study looks at how a virus found in animals (simian foamy virus) may spread to humans. It aims to learn who might be exposed and how the infection can be detected in a rural community, which could help future prevention.
YaoundéAges 5–90 - NCT06434337Recruiting
HPV diagnostic test study
This study tests a new, quick diagnostic test for HPV (the virus that can cause cervical cancer). Researchers want to see if the test works well compared to regular tests. If you are due for an HPV test or a related procedure, this study may be a good fit.
Houston, TexasAges 21 years+ - NCT02271243Recruiting
Find the source of bloodstream infections from central line germs
This study uses special genetic testing of bacteria from blood to figure out where central-line bloodstream infections come from. Results may help doctors better identify the source and improve prevention and treatment.
Boston, MassachusettsAges Any age - NCT07693881Recruiting
Preventing EBV reactivation with rituximab after stem cell transplant in children
This trial tests whether adding a drug called rituximab to the standard transplant plan can help prevent Epstein-Barr virus (EBV) from reactivating in children receiving a half-matched stem cell transplant. It may help reduce a common viral complication after transplant.
GuangzhouAges Up to 18 years - NCT07308782RecruitingPhase 2
