ABSTRACT
OBJECTIVE:
To investigate the impact of short-term exposure to air pollutants and meteorological variation on ED visits for primary spontaneous pneumothorax (PSP). MATERIAL ANDMETHODS:
We retrospectively identified PSP cases that presented at the ED of our tertiary center between January 2015 and September 2016. We classified the days into three types no PSP day (0â¯case/day), sporadic days (1-2â¯cases/day), and cluster days (PSP, ≥3â¯cases/day). Association between the daily incidence of PSP with air pollutants and meteorological data were determined using Poisson generalized-linear-model to calculate incidence rate ratio (IRRs) and the use of time-series (lag-1 [the cumulative air pollution level on the previous day of PSP], lag-2 [two days ago], and lag-3 [three days ago]).RESULTS:
Using multivariate logistic regression analysis, O3 (pâ¯=â¯0.010), NO2 (pâ¯=â¯0.047), particulate matters (PM)10 (pâ¯=â¯0.021), and PM2.5 (pâ¯=â¯0.008) were significant factors of PSP occurrence. When the concentration of O3, NO2, PM10, and PM2.5 were increased, PSP IRRs increased approximately 15, 16, 3, and 5-fold, respectively. With the time-series analyses, atmospheric pressure in lag-3 was significantly lower and in lag-2, was significantly higher in PSP days compared with no PSP days. Among air pollutant concentrations, O3 in lag-1 (pâ¯=â¯0.017) and lag-2 (pâ¯=â¯0.038), NO2 in lag-1 (pâ¯=â¯0.015) and lag-2 (pâ¯=â¯0.009), PM10 in lag-1 (pâ¯=â¯0.012), and PM2.5 in lag-1 (pâ¯=â¯0.021) and lag-2 (pâ¯=â¯0.032) were significantly different between no PSP and PSP days.CONCLUSION:
Increased concentrations of air pollutants and abrupt change in atmospheric pressure were significantly associated with increased IRR of PSP.Palavras-chave
