Mixed meal test to study diabetes from pancreas conditions
This study uses a special blood-sugar test (a mixed meal) to better diagnose and understand diabetes related to pancreatic cancer or chronic pancreatitis, and to compare it with other diabetes types. It may help researchers find clearer ways to tell these diabetes causes apart and understand how they work.
Los Angeles, CaliforniaAges 30–84 - NCT03492151Recruiting
Scans pancreatic cysts during a biopsy procedure
This trial tests a special camera (confocal laser endomicroscopy) used during an ultrasound-guided needle biopsy to help tell what type of pancreatic cyst is present. It may help doctors decide faster whether surgery is needed.
Scottsdale, ArizonaAges 18 years+ - NCT03504800Recruiting
Using OCT scans to diagnose irregular corneas
This study tests whether a special eye scan called OCT can better identify causes of irregular cornea shape. Results may help doctors sort out different cornea problems so treatment choices, like certain procedures, can be more targeted.
Portland, OregonAges 14–85 - NCT03525054Recruiting
Brain-and-speech study after suicidal thoughts or actions
This study looks at how people use language (free speech) after a suicidal gesture, idea, or related behavior that affected their life. The researchers use computer-based analysis to understand patterns in speech and thinking, which may help improve support and assessment.
BrestAges 15–30 - NCT03572465Recruiting
Ultrasound tests to diagnose fatty liver inflammation
This study checks whether special ultrasound measurements can help diagnose nonalcoholic steatohepatitis (NASH), a type of fatty liver disease. You may need a liver biopsy as part of routine care, and you may also be scanned with MRI to support the study tests.
Montreal, QuebecAges 18 years+ - NCT03621241Recruiting
Blood test study to help diagnose myelodysplastic syndrome
This study checks whether a detailed blood-cell test can help diagnose myelodysplastic syndrome (MDS), a bone marrow condition that can cause low blood counts. Your results are compared with standard bone marrow testing to see how well the blood test performs.
AmiensAges 18 years+ - NCT03691857Recruiting
Ultrasound computer tool for sudden breathing trouble in the ER
This study tests how well a computer-guided ultrasound method can quickly identify the cause of sudden breathing difficulty in the emergency room. It may help doctors make faster, more accurate decisions for treatment.
Châlons-en-ChampagneAges 50 years+ - NCT03716128Recruiting
Testing bone hormone changes in people with kidney problems
This study checks how kidney disease affects bone health by measuring hormones like PTH and related blood markers. It may help doctors better diagnose bone problems that can occur with poor kidney function.
HerlevAges 18 years+ - NCT03748485Recruiting
Chemo after surgery for certain stage III colon cancer
This trial studies whether adding chemotherapy after surgery helps people with colon cancer that was diagnosed before surgery as stage III and later found to be without certain high-risk features. It may help lower the chance the cancer comes back, but you must meet specific surgery and health criteria.
Guangzhou, GuangdongAges 18–75 - NCT03787056Recruiting
Blood test marker study in many cancer types
This study measures a blood marker called progastrin (at diagnosis and during treatment) to see how well it predicts response or outcomes. It may help doctors choose or monitor treatment more precisely for several cancer types.
