Life at Higher Elevation Linked to Lower Incidence of Lung Cancer

View | Comment

Lung cancer rates in both smokers and non-smokers are lower in higher-elevation counties in the western part of the United States, suggesting that oxygen may promote the incidence of lung cancer, according to a new study co-authored by a student at the Perelman School of Medicine at the University of Pennsylvania.

New Research Shows Fewer Deaths Related to RSV than Previously Thought

View

It’s a virus that has long been characterized as dangerous and even deadly, but new research shows infant deaths from respiratory syncytial virus (RSV) are actually quite uncommon in the 21st century. Researchers at the University of Utah have shown there are approximately 42 deaths annually associated with RSV in the United States - much lower than had been reported previously - and of those deaths, the majority are in infants and young children that have complex preexisting chronic conditions.

Fat a Culprit in Fibrotic Lung Damage

View | Comment

Researchers debate whether the lung tissue in pulmonary fibrosis is directly damaged, or whether immune cells initiate the scarring process – an important distinction when trying to find new ways to battle the disease. Now research shows that both processes may be important, and suggest a new direction for developing novel therapies.
