Wuhan, HubeiAges Up to 18 years - NCT07759583Recruiting
Breathing exercises for smog-related pneumonia
This study tests two breathing techniques—Buteyko breathing and incentive spirometry—to see which better improves oxygen levels, breathing difficulty, exercise tolerance, and mucus clearance in people with pneumonia caused by air pollution.
Lahore, Punjab ProvinceAges 25–40 - NCT07696364Recruiting
Testing a mouthwash for gum health
This trial tests a special mouthwash (chlorhexidine) to see how well it prevents gum inflammation. It compares a standard version to one that also reduces tooth staining. You may be eligible if you are healthy, do not smoke, and have at least 24 teeth with healthy gums.
