It's hard to smoke while you're jogging...

"Several plausible biological factors and mechanisms have been hypothesized linking physical activity to reduced lung cancer risk including: improved pulmonary function, reduced concentrations of carcinogenic agents in the lungs, enhanced immune function, reduced inflammation, enhanced DNA repair capacity, changes in growth factor levels and possible gene-physical activity interactions."

5-year study shows no hospital quality improvement

From Futurepundit:

"Despite concerted efforts, no decreases in patient harm were detected at 10 randomly selected North Carolina hospitals between 2002 and 2007, according to a new study from the Stanford University School of Medicine, Harvard Medical School and the Institute for Healthcare Improvement."

Cystic fibrosis: emerging pathogens

A key point: "It is not always clear whether or how these pathogens influence the progression of CF lung disease and how they should be treated."

The blog is up

I am Tim Allen and this is the first post to my blog.  It will focus on pulmonary pathology, and also discuss broader issues in pathology and medicine, medical-legal issues, and medical-ethical issues.
