GarchesAges 18 years+ - NCT05794061Recruiting
Testing new ways to assess brain and behavior health
This study is developing and checking better tests to understand neurological (brain-related) and psychiatric (mental health) conditions. If you have a diagnosed brain or mental health condition—or you’re being considered as a healthy person—your results will help researchers see how well these assessments work.
Milan, LombardyAges 20–100 - NCT05797649Recruiting
Test a pleural fluid blood marker to tell heart failure vs others
This study checks whether a substance called NT-proBNP in pleural fluid can better identify if fluid around the lung is caused by heart failure. If you fit, the results may help doctors choose faster, more accurate diagnosis for your pleural effusion.
Hong Kong, New TerritoriesAges 18 years+ - NCT05800132Recruiting
AI helps review routine breast mammograms for screening
This study tests whether an artificial intelligence (AI) system can help a second reader interpret routine breast screening mammograms. It may improve how consistently images are assessed, especially when the first reader calls them normal or benign.
AubagneAges 50–74 - NCT05804786Recruiting
Study of bronchoscopy to diagnose lung spots
This study follows people who have lung “spots” that look like possible lung cancer and need a biopsy to figure out what they are. It uses a guided breathing-tube procedure to safely collect tissue so doctors can make a diagnosis.
DaeguAges 19 years+ - NCT05825911Recruiting
Magnetocardiography test for suspected heart artery disease
This trial checks how accurate a magnetocardiography (MCG) scan is in people who are being evaluated for possible coronary artery disease. It may help doctors choose better diagnostic tests by comparing the scan results to the standard evaluation you are already getting.
Seoul, Eunpyeong-guAges 19–80 - NCT05827406Recruiting
Support system for psychiatric checkups in adults
This study looks at a helpful support system to improve how psychiatric symptoms are diagnosed and followed over time. It may help patients and clinicians by making checkups and next steps more organized.
StockholmAges 18 years+ - NCT05833321Recruiting
Testing a way to detect low muscle in women with certain cancers
This study looks at whether doctors can spot “low muscle” (sarcopenia) in everyday clinic care for people with ovarian or endometrial cancer who are planning to start chemotherapy. It may help your care team identify muscle loss early and potentially support better treatment planning.
Chambéry, SavoieAges 18 years+ - NCT05841914Recruiting
Testing a lab test to diagnose eye lymphoma from fluid
This trial checks how well a molecular (DNA/RNA) lab test can diagnose vitreo-retinal lymphoma, using eye fluid collected during a medically needed procedure. If you have signs doctors suspect this condition, the test may help confirm the diagnosis more accurately.
Lübeck, Schleswig-HolsteinAges 18 years+ - NCT05843851Recruiting
Newborn screening for rare cystinosis and hyperoxaluria
This study offers genetic screening to newborns to look for two rare metabolic conditions. It helps doctors find these conditions earlier, so treatment can start sooner if needed.
Hanover, Lower SaxonyAges 1 day–3 days - NCT05853783Recruiting
Testing a mouth test on biopsy samples from abnormal lesions
This trial looks at archived (saved) mouth biopsy samples to see how well the STRATICYTE™ test can identify potentially dangerous “pre-cancer-like” changes. It may help doctors screen or better understand which abnormal areas in the mouth later turn into oral cancer.
Birmingham, AlabamaAges 18 years+ - NCT05855941Recruiting
Imaging tests to better predict and diagnose gynecologic cancers
This trial studies how well medical imaging (especially MRI) can help predict outcomes and improve diagnosis in people newly diagnosed with certain gynecologic cancers. It may help doctors make more accurate treatment decisions by comparing imaging results to the final cancer type and stage.
UmeåAges 18 years+ - NCT05889013Recruiting
Nasal swab testing to guide care for kids with breathing issues
This study checks whether special nose tests help doctors choose the best treatments for children with long-term breathing and airway symptoms. It may help your child get more targeted care based on the test results.
Hartford, ConnecticutAges 2 years+ - NCT05889559Recruiting
Testing a fluid drainage method to detect leg pressure problems
This study looks at a special drainage measurement (“tissue ultrafiltration”) to better detect and treat acute compartment syndrome, a dangerous increase in pressure in the leg after major injury. It may help doctors identify who needs urgent treatment and improve outcomes after severe leg fractures or crush injuries.
Baltimore, MarylandAges 18–60 - NCT05893342Recruiting
Checking frailty during surgery in older adults
This study looks at “frailty,” or how well the body may handle stress, around the time of surgery in people age 65 and older. It may help doctors better understand who is at higher risk and how to plan care around surgery.
Las Palmas de Gran Canaria, Las PalmasAges 65 years+ - NCT05898269Recruiting
Predicting fluid needs while lying face down in ARDS
This study tests a way to predict whether you will benefit from a fluid bolus (a small amount of IV fluid) while you are lying face down for ARDS. It uses continuous heart monitoring to guide or evaluate fluid decisions and may help clinicians avoid too much or too little fluid.
Clermont-FerrandAges 18 years+ - NCT05921812Recruiting
Blood tests for lymphoma using small RNA markers
This study looks at tiny blood molecules called microRNAs to see if they can help diagnose non-Hodgkin's lymphoma. If you are newly diagnosed and have no other cancers, your blood test results may be compared to known patterns to improve diagnosis.
SohagAges 18–75 - NCT05937334Recruiting
