NEWS BRIEFS FROM THE APRIL ISSUE OF CHEST
ASTHMA EPISODES DECREASE WITH REDUCED ETS EXPOSURE
Environmental tobacco smoke (ETS) exposure is associated with poor asthma outcomes in children.
However, a new study shows that reducing exposure to ETS may improve asthma outcomes. University of
Alabama researchers followed 240 children with asthma who were either receiving usual care or supervised
asthma therapy. No smoking cessation counseling or ETS exposure education was provided to caregivers;
however, children were given 20 minutes of asthma education that incorporated discussion on the avoidance
of asthma triggers, including ETS. Asthma morbidity and ETS exposure were collected from caregivers via
telephone interviews at baseline and at 1-year follow-up. Among children whose ETS exposure decreased
from baseline, fewer hospitalizations and ED visits were reported. Additionally, these children were 48
percent less likely to experience an episode of poor asthma control. These findings emphasize the importance
of ETS exposure reduction as a mechanism to improve asthma control and morbidity. This study is published
in the April issue of the journal CHEST.
FOOT SURGERY PATIENTS RUN LOW RISK FOR BLOOD CLOTS
Although recent surgery is a risk factor for deep vein thrombosis (DVT) or blood clots, a new study suggests
that patients who undergo podiatric surgery may have a relatively low risk for thrombolytic events. In a 5-
year retrospective analysis, researchers from Kaiser Permanente Center for Health Research reviewed the
charts of 7,264 patients who underwent podiatric surgical procedures. Of the 16,804 total procedures
recorded, overall incidence of post-procedure venous thromboembolism (VTE) was 0.30 percent. The
incidence of VTE increased slightly with the presence of risk factors, including prior VTE, use of hormone
replacement therapy, and obesity. Researchers conclude that the low overall risk of VTE in podiatric surgery
suggests routine prophylaxis is not warranted. This study is published in the April issue of the journal CHEST.
RARE LUNG DISEASE PREVALENT IN TENNESSEE APPALACHIA
New research confirms that blastomycosis, an uncommon lung disease caused by a fungus, continues to be a
problem in the Appalachian area of northeastern Tennessee. The disease, characterized by flu-like
symptoms, is most often reported in people with exposures to wooded sites (e.g., farmers, forestry workers,
hunters, and campers). In a retrospective study, researchers from East Tennessee State University found that
blastomycosis was still prevalent in the northeastern Tennessee area (n=67), increasing slightly from the
research team’s previous findings from 1980 to 1995 (n=55). Researchers speculate that, as the region
continues to experience a population growth, additional cases of the disease are to be expected. This study is
published in the April issue of the journal CHEST.
