MoscowAges 18 years+ - NCT05561504Recruiting
Study of stomach bacteria resistance in adults
This study looks at how common a stomach bacteria infection is and which antibiotics still work. You may help researchers by providing consent for related study participation and sample tracking.
MunichAges 18 years+ - NCT06204484Recruiting
MRD-guided Chemo Timing for Early Colon Cancer
This trial is for people with early-stage colon cancer (stage II high-risk or stage III low-risk) that is not MSI-H. It uses a blood test (MRD) to see if you can safely delay or skip extra chemotherapy after surgery, based on whether the test finds any leftover cancer cells.
Guangzhou, GuangdongAges 18–70 - NCT06057350Recruiting
Surgery versus endoscopy for early colon cancer with uncertain margins
This trial compares surgery versus an endoscopic procedure for people who had a colon polyp removed but some cancer cells may still be present at the edges. The goal is to see which approach leads to better outcomes and fewer side effects for early-stage colon cancer.
Oslo, AkershusAges 40 years+ - NCT07868549Enrolling by invitation
Comparing three mouth care methods for intensive care patients
This study tests three different mouth care routines to see which one reduces bacteria in the mouth most effectively. It aims to find a simple way to prevent infections in patients who are very ill in the hospital intensive care unit.
ZagrebAges Any age - NCT05495048Recruiting
Transvaginal surgery vs standard laparoscopy for right colon removal
This study compares two surgical approaches for removing the right side of the colon in certain women with colon cancer or a high-risk pre-cancer. It aims to see whether the less invasive transvaginal approach can be done safely and work as well as standard laparoscopic surgery.
ShanghaiAges 18–75 - NCT06281145Recruiting
Stress reduction for breast or colon cancer patients
This study tests a stress-reducing program for people with breast or colon cancer. It uses a technique called heart rate variability biofeedback to help you manage stress during treatment.
BratislavaAges 18 years+ - NCT06018792Recruiting
New blood test for faster sepsis diagnosis in children
This trial tests a new, faster way to find bacteria in the blood of children with suspected sepsis. It uses a molecular test that may give results sooner than standard cultures, helping doctors treat infections more quickly.
AmsterdamAges birth–18 years - NCT05714124Recruiting
Testing liver procedures to treat tumors when surgery isn’t possible
This trial studies different ways to place treatments inside the liver to control liver tumors when they can’t be removed with surgery or ablation. It may help certain people by improving how well the tumor is treated while keeping liver function safer.
MilanAges 18 years+ - NCT06390696Recruiting
Sand play for eczema: a biodiversity study
This study looks at whether playing in sand with different types of natural materials (to increase your contact with harmless microbes) can improve eczema symptoms. You would stop using your usual eczema creams during the trial to see if the sand play alone helps.
Helsinki, UusimaaAges 2–5 - NCT06466707Recruiting
Collecting gut bacteria samples from healthy volunteers
This study collects stool or other samples from healthy people to learn more about the helpful bacteria in our gut. It may help researchers understand how these bacteria affect health.
Ghent, East FlandersAges 2–70 - NCT06390878Recruiting
Study on natural kindergarten yards
