Aspiration pneumonia

This study looks at whether special cells, called 'showering cells,' found in lung fluid can help doctors diagnose aspiration pneumonia (a lung infection from inhaling food or liquid). Researchers will compare 94 adults with and without the condition to see if these cells are a r…

This study uses ultrasound to check if pressing on the neck (cricoid pressure) during anesthesia prevents stomach contents from entering the lungs in children. Researchers will measure the esophagus before and after pressure in 35 kids aged 0-17. They also test if pressing from t…

This study aims to see if a simple, non-invasive breathing test can accurately measure the acidity (pH) in the airways, which is often abnormal in lung diseases. Researchers will compare results from this breath test with standard methods in 150 healthy volunteers and people with…

This study watches 200 people with lung, gut, or hormone diseases over time using special brain scans (PET). It aims to see how these diseases change brain activity and whether those changes can predict tumor return, spread, or survival. No new treatment is tested—just observatio…

This study looks at how GLP-1 receptor agonists (like Ozempic or Wegovy) affect how fast the stomach empties before surgery. These drugs are used for weight loss and diabetes, but they slow stomach emptying, which could raise the risk of food or liquid entering the lungs during a…
