Middle lobe syndrome

This study compares two ways of setting the breathing machine during gynecologic laparoscopic surgery to prevent lung collapse (atelectasis). One method uses a standard fixed pressure, while the other adjusts the pressure to each patient's lung mechanics. The researchers will use…

This study tests how often doctors should give a brief lung inflation (called a recruitment maneuver) during abdominal laparoscopic surgery to keep the lungs open. Fifty-two older adults having elective surgery will receive these puffs at different intervals, starting every 30 mi…

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…
