Portland, OregonAges 21–40 - NCT04578340Recruiting
Follow-up after hernia repair with mesh
This study looks at long-term outcomes after abdominal hernia surgery where a mesh patch was used. It may help doctors understand what to expect long-term and how well mesh repair works over time.
Evanston, IllinoisAges 18 years+ - NCT00902447Recruiting
Blood and tissue collection for future research studies
This trial is a tissue and blood bank that collects samples for future research. You may be asked to give blood and/or tissue again later, but it is meant to be done without interfering with your care.

Hamilton, OntarioAges 20–100 - NCT03136302Recruiting
Tracking brain signals during deep brain stimulation
This study compares two ways of measuring brain activity—MRI-based brain mapping and electrical brain testing—during deep brain stimulation. It may help doctors better target stimulation to improve symptoms like movement problems or long-lasting pain.
Halifax, Nova ScotiaAges Any age - NCT03162211Recruiting
Improving care for depression using patient feedback
This trial looks at how collecting and using feedback can improve outcomes for people with major depression or persistent depression. You may be asked to share your experiences so the care team can adjust how depression support is delivered.

Comparing new SBRT to standard radiation for prostate cancer
This trial compares a newer, more precise type of radiation (adaptive SBRT) with standard image-guided radiation for prostate cancer. It aims to see if the newer approach is better at targeting the tumor while reducing side effects.
Toronto, OntarioAges 18 years+ - NCT01617408Recruiting
Brain stimulation and vision testing in healthy adults
This study uses brain stimulation and brain imaging (MRI) along with vision tests to understand how the brain supports seeing. You might be eligible if you are a healthy adult and can safely complete MRI and stimulation tasks.
Bethesda, MarylandAges 18–50 - NCT03552705RecruitingPhase 2

Stanford, CaliforniaAges 18–30 - NCT03253705Recruiting
Donate small blood samples to study heart and inflammation health
This study collects small blood samples (and sometimes samples during treatment) to help researchers understand diseases involving the heart, inflammation, and blood vessel function. It may help improve future tests and treatments by giving scientists usable human data.
Bethesda, MarylandAges 18–100 - NCT02010866Recruiting
OHSU healthcare staff support for stressed members
