Every month I try to read an open-access article. Then I share the link with my followers. This is to encourage clinicians to read articles, stay up to date, and continue to grow.

This month I found a great piece to share with you.  The objective of this paper is to “to assess the association of respiratory symptoms and lung function with occupation in the Burden of Obstructive Lung Disease” (p6).

“We found no significant associations between post-bronchodilator FEV1/FVC ratio or FVC and work in any of the high-risk occupations. FEV1/FVC was low in coal miners, sandblasters, chemical or plastic processors and steel millers with long durations of exposure, but these associations were not statistically significant. Moreover, there was no evidence of exposure-response associations of either post-bronchodilator lung function measures with any of the specific occupations.”

“Chronic phlegm but not chronic airflow obstruction was more likely to occur among users than among never-users of solid fuels.”

“The occurrence of occupational asthma, presenting with wheeze and breathlessness without affecting post-bronchodilator lung function. This can be induced by substances in workplaces such as animal dusts, flour, chemicals and metals.”
