Abstract Background: Numerous studies have confirmed the association of ambient temperature and air pollution with a higher risk of morbidities, yet few have addressed their effect on the ocular system. The purpose of this study was to assess the association between temperature, air pollution, and emergency room visits for conjunctivitis.Methods: In this case-crossover study, the records of all emergency room visits to Soroka University Medical Center (SUMC) from 2009 to 2014 were reviewed for patients with conjunctivitis. Daily exposure to fine and coarse particulate matter and temperature were determined by a hybrid model involving satellite sensors.Results: 6001 patients were diagnosed with conjunctivitis in the SUMC emergency room. We discovered a positive association between temperature increments and incidence of conjunctivitis. The strongest effect was found during summer and autumn, with an immediate (lag0) incidence increase of 8.1% for each 1 °C increase in temperature (OR 1.088 95%CI 1.046;1.132) between 24 and 28 °C in the summer and 7.2% for each 1 °C increase in temperature (OR 1.072 95%CI 1.036;1.108) between 13 and 23 °C in the autumn. There was no statistically significant association between fine and coarse particulate matter and conjunctivitis incidence.Conclusion: Temperature increases during summer and autumn are significantly associated with an increased risk of conjunctivitis. Conjunctivitis is not associated with non-anthropogenic air pollution. These findings may help community clinics and hospital emergency rooms better predict conjunctivitis cases and will hopefully lead to improved prevention efforts that will lower the financial burden on both the individual and the public.

Methods In this case-crossover study, the records of all emergency room visits to Soroka University Medical Center (SUMC) from 2009 to 2014 were reviewed for patients with conjunctivitis. Daily exposure to fine and coarse particulate matter and temperature were determined by a hybrid model involving satellite sensors. Mean relative humidity was obtained from the Ministry of Environmental Protection meteorological monitoring station located in Beer-Sheva. Results Six hundred one patients were diagnosed with conjunctivitis in the SUMC emergency room. We discovered a positive association between temperature increments and incidence of conjunctivitis. The strongest effect was found during summer and autumn, with an immediate (lag0) incidence increase of 8.1% for each 1 °C increase in temperature (OR = 1.088, 95%CI: 1.046–1.132) between 24 and 28 °C in the summer and 7.2% for each 1 °C increase in temperature (OR = 1.072, 95%CI: 1.036–1.108) between 13 and 23 °C in the autumn.

Abstract Background Numerous studies have confirmed that ambient temperature and air pollution are associated with higher risk of morbidities to different systems of the human body, yet few have addressed their effect on the ocular system. The purpose of this study is to determine the association between temperature, air pollution and emergency room visits for non-specific conjunctivitis Methods In this retrospective cohort study, the records of all emergency room visits to Soroka University Medical Center (SUMC) from 2009 to 2014 were reviewed for patients with conjunctivitis. Exposure to fine and coarse particulate matter and temperature were assessed by a hybrid model that incorporated daily satellite remote sensing. Results The records of the 6001 patients who visited the SUMC emergency room with conjunctivitis, together with the meteorological data, revealed a positive association between temperature increment and incidence of conjunctivitis. The strongest effect was found during summer and autumn: the incidence increased 8.1% for each 1oC rise in temperature between 24oC and 28oC in the summer, and 7.2% for each 1oC rise in temperature between 13oC and 23oC in autumn. The association between fine and coarse particulate matter and incidence of conjunctivitis was not statistically significant. Conclusion High ambient temperature is significantly associated with an increased risk of nonspecific conjunctivitis in summer and autumn and not in spring and winter. Conjunctivitis is not associated with air pollution. The findings can assist community clinics and hospital emergency rooms prepare for the upticks in the condition during certain seasons and acute rises in temperatures, lowering the financial costs to both the individual and the public.

Trading Ratio

This study analyzes the direct and indirect effects of air pollution on the return and volatility of the KOSPI index through the trading ratio by investor type. The main results are as follows. First, air pollutants have a direct effect on volatility; coarse particulate matter (PM10) and fine particulate matter (PM2.5) have a negative effect on volatility. Second, air pollutants have a significant effect on the trading ratio by investor type; as the concentration of fine particulate matter (PM2.5) increases, the trading ratio of institutionals and those of foreigners decrease. Third, the effect of cumulative exposure of air pollutants on stock return and volatility is greater than that of daily exposure. Although there is no effect on daily exposure to air pollution, stock return decreases during cumulative exposure to fine particulate matter (PM2.5), nitrogen dioxide (NO2), and carbon monoxide (CO). The volatility changes significantly with cumulative exposure compared to daily exposure to coarse particulate matter (PM10), fine particulate matter (PM2.5), ozone (O3), nitrogen dioxide (NO2) and sulfur dioxide (SO2). Fourth, air pollutants have an indirect effect on stock return and volatility through trading ratio by institutional and foreign investors. In particular, the effect of air pollution through the foreign investors’ trading ratio is a remarkable result revealed in this study.
