Relationship between pollen concentrations and short-acting B2-agonists (SABA) bronchodilator sales in central France: a daily time-series analysis over a 5-year period

Seasonal asthma may be associated with pollen exposure, but the pollens responsible for these exacerbations are not well known. The association between ambient pollen and asthma reflected in emergency department (ED) visits and hospitalizations, although studied intensively, has shown inconsistent results. This would be explained by differences between population, climate, and measurement of pollen.We can talk about maple, charm, oak pollen and grasses, with in the Darrow's study a 3% increase in emergency department visits. Another study shows that birch and oak pollen peaks were associated w... Mehr ...
