Guangzhou, GuangdongAges 18–75 - NCT07743021Recruiting
Blood sample study for better health screening
This study collects blood samples and health information over time to improve early detection of diseases. It may help researchers find ways to prevent serious conditions.
BalatonfüredAges 40 years+ - NCT06529913Recruiting
Metals, pollutants, and risk of allergies
This study looks at whether heavy metals, nanoparticles, and other pollutants in the environment increase the risk of allergic diseases like contact dermatitis. If you have a metal allergy or are a healthy adult, you may help researchers understand how these exposures affect your health.
BolognaAges 18 years+ - NCT06809660Recruiting
Gut bacteria and cancer risk from everyday chemicals
This study looks at how chemicals in the environment (called endocrine disruptors) might affect the natural bacteria in your gut and whether that could play a role in colorectal cancer. If you are having a colonoscopy (endoscopy), you may be able to participate.
PoitiersAges 18 years+ - NCT07397975Recruiting
