Effect of exposure to an Asian dust storm on fractional exhaled XXXX in adult @entity565 @entity1 in Western Japan.

@entity1 @entity32 @entity565 @entity842 @entity1576
BACKGROUND: Epidemiological investigations indicate that an Asian dust storm (ADS) can aggravate @entity1576 . However, the effects of ADS on @entity32 remain unclear. The aim of this study was to investigate the association of exposure to ADS with @entity32 . METHODS: The subjects were 33 adult @entity1 with @entity565 who measured daily peak flow expiratory (PEF) from March to May 2012. Fractional exhaled @entity842 (FeNO) was measured before and after ADS. RESULTS: The FeNO values were 13.8  13.7 ppb before the ADS and 20.3  19.0 ppb after the ADS, with no significant difference. There was also no significant association of PEF with ADS exposure. However, the increase of FeNO after ADS exposure was proportional to the decrease of PEF (R=-0.78, P<0.0001). CONCLUSION: These results suggest that @entity32 aggravated by ADS exposure may induce a decrease in pulmonary function in some adult @entity1 with @entity565 . J. Med.
