Blood test after lung tumor surgery to find hidden disease
This study uses a special blood test to look for tiny traces of lung cancer after surgery. It aims to find “minimal residual disease,” meaning cancer cells that may still be hiding after your tumor is removed.
Toronto, OntarioAges 18 years+ - NCT05212129Recruiting
Stimulation of the ear nerve to help gut symptoms
This study tests whether stimulating a nerve in the ear (called auricular vagal nerve stimulation) can improve upper gut symptoms in teens who may have hypermobile Ehlers-Danlos syndrome (hEDS) or hypermobile spectrum disorder (HSD). It also checks whether this treatment helps nerves that control the body (autonomic nervous system) and how well the gut moves.
Milwaukee, WisconsinAges 10–18 - NCT05250375Recruiting
Study of mitochondrial muscle diseases over time
This natural history study follows children and adults with suspected or confirmed mitochondrial myopathy to better understand symptoms and how the condition changes. It may also include healthy participants to compare test results and improve future treatments.
Philadelphia, PennsylvaniaAges birth–100 years - NCT05240885Recruiting
Metabolic and functional effects of aging in health and disease
This study looks at how aging affects your body's metabolism and physical function, especially if you have heart failure or have recently been in the hospital. It may help doctors understand how to better support recovery and health as we age.
