In a study published in the American Journal of Respiratory and Critical Care Medicine, the UNC scientists found that the lungs of vapers -- like the lungs of smokers -- have elevated levels of protease enzymes, a condition known to cause emphysema in smokers. The researchers also found that the nicotine in vaping liquids is responsible for the increase in protease enzymes.
Researchers at Rutgers and other institutions have discovered how muscle contraction (bronchospasm) in the airway, which cause breathing difficulty in people with asthma, occur by creating a microdevice that mimics the behavior of the human airways. The study, published in the journal Nature Biomedical Engineering, could lead to new treatment strategies for respiratory diseases.
A steady supply of its favorite food helps a deadly bacterium thrive in the lungs of people with cystic fibrosis, according to a new study by Columbia researchers.
A new study from Washington University School of Medicine in St. Louis supports evidence that children with mild asthma can effectively manage the condition by using their two inhalers -- one a steroid and the other a bronchodilator -- when symptoms occur. This is in contrast to the traditional method of using the steroid daily, regardless of symptoms, and the bronchodilator when symptoms occur. The as-needed use of both inhalers is just as effective for mild asthma as the traditional protocol, according to the investigators.
A new multicenter study at Columbia University links long-term exposure to air pollution, especially ozone, to development of emphysema, accelerating lung disease progression as much as a pack a day of cigarettes.
Whether exposure to outdoor air pollutants is associated with emphysema progression and change in lung function was the focus of this observational study. The study included 7,071 participants from the Multi-Ethnic Study of Atherosclerosis studies conducted in six US metropolitan regions (New York; Los Angeles; Chicago; Baltimore; Winston-Salem, N.C.; and St. Paul, Minn.). Computed tomographic (CT) scans were used to assess changes in emphysema (measured for density as a percentage of lung pixels) and lung function testing was done.
Certain traits may define a type of obstructive sleep apnea that can be effectively treated with an oral appliance, according to new research published online in the Annals of the American Thoracic Society.
Researchers describe minimally invasive new tool for viewing differences in the nasal airways of cystic fibrosis patients in vivo at a cellular level.
University of Houston biomedical engineer Chandra Mohan has discovered blood clotting proteins in the urine of patients with Lupus Nephritis which is the leading cause of death in lupus patients. The new biomarker discovery could lead to better clinical disease monitoring.
The American Thoracic Society has published an official clinical guideline on the evaluation and management of obesity hypoventilation syndrome in the Society's Aug. 1, 2019 American Journal of Respiratory and Critical Care Medicine.
