This study is analyzing the exhaled breath of 5,000 people with lung or airway diseases to find unique molecular patterns. The goal is to better identify and distinguish different respiratory conditions and improve disease management. Participants simply provide breath samples, a…

This study aims to identify unique patterns in exhaled breath that may be linked to certain medications or lung diseases. Researchers will collect breath samples from 1500 adults and analyze them using a sensitive technique called mass spectrometry. The goal is to find chemical m…

This study tracks 420 people to see how bariatric surgery affects drinking behavior using a special device called a drinkometer. It measures things like sip size and speed, and looks at how gut hormones and sex differences play a role. The goal is to better understand why surgery…

This study looks at why some people develop nerve pain after a spinal cord injury. Researchers will use pain tests, nerve measurements, and heart rate checks in 300 participants to understand the underlying causes. The goal is to better classify pain types, not to test a new trea…

This study compares how well stroke neurologists and a deep learning AI model predict recovery in 250 stroke patients. Researchers will track actual disability at 24 hours and 3 months, then compare those results to predictions made by doctors and the AI. The goal is to understan…

This study aims to better understand primary immune deficiencies (PID), a group of diseases where the immune system doesn't work properly. Researchers will collect blood, stool, urine, and tissue samples from 300 people with PID and healthy volunteers to analyze immune responses.…

This study looks at why about half of stroke patients don't recover well even after doctors successfully remove a blood clot from their brain. Researchers will use special MRI scans to measure blood flow changes in the brain at 3 days, 7 days, and 90 days after the procedure. The…
