Study of life-threatening infections to find genetic causes
This trial studies people who have had a life-threatening infection to look for genetic reasons why some infections are so severe. If you or a child had a serious infection—like severe flu, meningitis, or a deep abscess—that could not be explained by a weak immune system from other causes, this study may help find answers.

High flow oxygen to reduce infections in obese gynecologic cancer patients
This trial tests whether giving high flow oxygen during and after surgery can lower the risk of infections in obese women with gynecological cancer. It may help improve recovery after surgery.
AthensAges 18–85 - NCT07476274Recruiting
Study of pneumonia after heart bypass surgery
This trial looks at pneumonia that happens in the hospital after coronary artery bypass surgery. It aims to understand who is at risk and how to better prevent or treat it.
Tomsk, Tomsk OblastAges 18 years+ - NCT07474831Recruiting
Probiotic treatment to prevent repeat vaginal infections
This trial tests whether taking a probiotic (a beneficial bacteria) can reduce the number of times you get bacterial vaginosis, a common vaginal infection. It may help you have fewer infections in the future.
Forlì, Emilia-RomagnaAges 18–45 - NCT07474194RecruitingPhase 4
Cleaning the vagina before c-section to prevent infection
This trial compares two ways to clean the vagina before a planned cesarean section to see which one better prevents infections after surgery. It may help you if you are having a planned c-section.

Swiss study on joint replacement revision for infection
This study looks at people who need a second (revision) surgery on a large joint replacement like a hip, knee, shoulder, ankle, or elbow because of a suspected or confirmed infection. The goal is to learn more about these infections and improve care.
AarauAges 18 years+ - NCT07478172Recruiting
Electrical muscle stimulation exercise for neuromuscular disease
This study tests whether whole-body electrical muscle stimulation (using small electrodes on the skin) can help adults with certain neuromuscular diseases exercise and improve muscle strength. It may be an option if you can stand for about 15 minutes at a time and have some muscle strength left.
Columbia, MissouriAges 18 years+ - NCT07478029Recruiting
PEG bowel preparation study for appendectomy patients
This study tests if a bowel-cleaning solution (PEG) works well before colonoscopy. It compares people who have had their appendix removed to those who haven't.
Wuhan, HubeiAges 18–75 - NCT07478484RecruitingPhase 4
Different ways to take antibiotics for resistant infections
This trial tests two different schedules of a combination of antibiotics (ceftazidime-avibactam plus aztreonam) for people with serious infections caused by bacteria that are hard to treat. It aims to find the best way to give these medicines.
Nanjin, JiangsuAges 18–100 - NCT07476339RecruitingPhase 4
Returning to HIV Care with Biktarvy
This trial tests the medication Biktarvy (bictegravir, emtricitabine, and tenofovir alafenamide) for people with HIV who have stopped taking their antiretroviral therapy (ART) for at least 12 weeks and are ready to restart treatment. It aims to see how well the medication works when restarting care.
