Higher risk for tuberculosis diagnosis with wildfire smoke exposure
Erika M. Moseson
Heightened odds for a tuberculosis diagnosis were related to exposure to ambient air pollution that included wildfire smoke, including 23% increased odds for TB with each air pollution event related to wildfires over 6 months, according to results published in American Journal of Respiratory and Critical Care Medicine. Also, Erika M. Moseson, MD, shares her Perspective. Read more.
Link between wildfire smoke, preterm birth driven by spontaneous preterm birth
Each additional day of wildfire smoke exposure in California was associated with 0.3% greater odds of spontaneous preterm birth, with an average of 7.5 days of exposure from 4 weeks before conception to 20 weeks’ gestation, among other impacts presented at The Pregnancy Meeting in February.

Wildfire air pollution may adversely affect IVF outcomes

Climate change cited as cause of recent increases in asthma, allergy prevalence
The effects of climate change including increases in PM2.5 pollution from wildfires may be responsible for recent increases in the prevalence of asthma and allergy disorders, Marc E. Rothenberg, PhD, of Cincinnati Children’s Hospital, told Healio. Read more.
CDC experts issue climate change information, resources for allergists, immunologists
Droughts resulting from climate change can increase the risk for wildfires, leading to increased respiratory symptoms for people with asthma due to smoke, the CDC said, adding that wildfires also may impact access to medications and medical services while making the refrigeration of perishable, allergen-free foods challenging as well.

Air pollution raises risk for first-year ED visits in preterm, full-term infants

Q&A: Particulate matter air pollution standards need to be stronger
Laura Kate Bender
Changing the current EPA standard for annual PM2.5 from wildfires and other sources from 12 µg/m3 to 9 µg/m3 and could save 4,200 lives a year, but a standard of 8 µg/m3 could save 9,200 lives, Laura Kate Bender, national assistant vice president of healthy air at the American Lung Association, told Healio.
