Pulmonary Research: Statins reduce major complications following lung surgery ♦ Tuberculosis bacteria hide in low oxygen niches of bone marrow stem cells ♦ Highly educated women stop smoking if the cost goes up

Acute pulmonary fibrosis may respond to autoimmune disease therapy  Patients with acute exacerbations of idiopathic pulmonary fibrosis responded well to therapies similar to those used to treat autoimmune diseases,  IPF, a devastating lung disease, scientists report. Idiopathic pulmonary fibrosis is a disease of unknown origin with no approved treatments. It results in scar tissue building up in the lungs. It affects more than 100,000 people in the United States and 5 million worldwide. The median survival rate is less than three years, and only 20 percent of patients survive five years beyond diagnosis.
Tuberculosis bacteria hide in low oxygen niches of bone marrow stem cells A new study is helping to shed light on latent tuberculosis and the bacteria's ability to hide in stem cells. Some bone marrow stem cells reside in low oxygen (hypoxia) zones.
Highly educated women stop smoking if the cost goes up Cigarette prices and images on cigarette packets have an impact on women in terms of continuing to smoke or quitting. In fact, less educated women are more responsive to pictorial labels on cigarette packets, as revealed by a Spanish study that has analyzed, for the first time, the generation differences among female smokers, a group which, despite policy measures, has not stopped growing.
Statins show promise to reduce major complications following lung surgery Statins have been shown to reduce complications from cardiovascular surgery. To determine whether statins might also help those undergoing major lung surgeries, a team of researchers conducted a well-designed study that randomized patients to receive either a statin or placebo before and after surgery. They found that patients undergoing major lung resection experienced fewer complications overall, however, the differences between groups for specific complications or changes in inflammatory markers failed to reach statistical significance.
