Evidence of the acute effects of air pollutants on ischemic heart disease (IHD) hospitalizations based on the entire population of a megacity in central China is lacking. All IHD hospitalization records from 2017 to 2018 were obtained from the Wuhan Information Center of Health and Family Planning. Daily air pollutant concentrations and meteorological data were synchronously collected from the Wuhan Environmental Protection Bureau. A time-series study using generalized additive models was conducted to systematically examine the associations between air pollutants and IHD hospitalizations. Stratified analyses by gender, age, season, hypertension, diabetes, and hyperlipidemia were performed. In total, 139,616 IHD hospitalizations were included. Short-term exposure to air pollutants was positively associated with IHD hospitalizations. The age group ≥76 was at higher exposure risk, and the associations appeared to be more evident in cold seasons. PM2.5 and PM10 appeared to have greater effects on males and those without hypertension or diabetes, whereas NO2 and SO2 had greater effects on females and those with hypertension or diabetes. The risk of IHD hospitalization due to air pollutants was greater in people without hyperlipidemia. Our study provides new evidence of the effects of air pollution on the increased incidence of IHD in central China.

Abstract Background There are few studies focused on the correlations between ambient air pollution and abdominal pain, especially in emergency departments in China. Method: Daily data (from January 1, 2016 to December 31, 2018), including air pollution concentration (SO2, NO2, PM2.5, PM10, CO, and O3) and meteorological variables, for daily emergency room visits (ERVs) were collected in Wuhan, China. We conducted a time-series study to investigate the potential correlation between six ambient air pollutants and ERVs for abdominal pain and their effects, in different genders, ages and seasons. Results A total of 16,306 abdominal pain ERVs were identified during the study period. A 10-µg/m3 increase in concentration of SO2, NO2, PM2.5, PM10, CO, and O3 corresponded respectively to incremental increases in abdominal pain of 6.12% (95% confidence interval [CI]: -0.44-13.12), 1.65% (95%CI: -0.25-3.59), 1.12% (95%CI: -0.18-2.44), 0.38% (95%CI: -1.09-1.87), 9.87% (95%CI:3.14–17.05) and 1.11% (95%CI: 0.03–2.21). We observed significant correlations between CO and O3 and daily abdominal pain ERVs increase, and positive but insignificant correlations between the other pollutants and ERVs. The effects were stronger mainly for females (especially SO2 and O3) and younger people (especially CO and O3). The correlations of PM2.5 and PM10 were stronger in cool seasons, while the correlation of CO was stronger in warm seasons. Conclusion Our time-series study suggested that short-term exposure to air pollution (especially CO and O3) was positively correlated with ERVs for abdominal pain in Wuhan, China, and that their effects varied by season, gender and age. These data can add evidence on how air pollutants affect the human body, and may prompt hospitals to take specific precautions on polluted days and maintain order in emergency departments made busier due to the pollution.

CONTEXT AND OBJECTIVE: Little has been discussed about the increased risk of stroke after exposure to air pollutants, particularly in Brazil. The mechanisms through which air pollution can influence occurrences of vascular events such as stroke are still poorly understood. The aim of this study was to estimate the association between exposure to some air pollutants and risk of death due to stroke.DESIGN AND SETTING: Ecological time series study with data from São José dos Campos, Brazil.METHODS: Data on deaths due to stroke among individuals of all ages living in São José dos Campos and on particulate matter, sulfur dioxide and ozone were used. Statistical analysis was performed using a generalized additive model of Poisson regression with the Statistica software, in unipollutant and multipollutant models. The percentage increase in the risk of increased interquartile difference was calculated.RESULTS: There were 1,032 deaths due to stroke, ranging from 0 to 5 per day. The statistical significance of the exposure to particulate matter was ascertained in the unipollutant model and the importance of particulate matter and sulfur dioxide, in the multipollutant model. The increases in risk were 10% and 7%, for particulate matter and sulfur dioxide, respectively.CONCLUSION: It was possible to identify exposure to air pollutants as a risk factor for death due to stroke, even in a city with low levels of air pollution.

Abstract Introduction Air pollution is considered to be one of the main risk factors for public health, in particular its impact on the disorders of the pulmonary and cardiovascular system and the related mortality. Purpose This study was carried out to assess the influence of the atmospheric conditions and air pollutants on mortality in the population of the big city in the eastern Poland. Materials and methods Based on the data from the Central Statistical Office, the number and causes of the deaths of the city residents in the period 2008–2017 were analyzed. The study utilized the data recorded by the Provincial Inspectorate for Environmental Protection station and the Institute of Meteorology and Water Management during the analysis period. Multivariate Poisson regression was used for statistical analysis. Results A total of 34,005 deaths had been recorded, in which women accounted for 47.5%. The proportion of cardiovascular-related deaths was 48% (N=16,370). The main causes of deaths in the female population were chronic ischemic heart disease (N=1683; 10.42%) and cerebral infarction (N=1617; 10.01%), while in the male population, in addition to chronic ischemic heart disease (N=1530; 8.57%), deaths were caused mainly by malignant neoplasm of the bronchus and lung (N=1555; 8.71%). During the analysis, it was observed that the 1-day norm of sulfur dioxide (SO2) recommended by the World Health Organization (WHO) guidelines was sporadically exceeded (N=18, 0.50% of analyzed days), while the daily norm for the particulate matter with a diameter of 2.5 μm or less (PM2.5) was exceeded on 688 days (23.60% of analyzed days). In the female group, excluding the seasonal impact, an increase of SO2 concentration by 1-μg/m3 (RR 1.05, 95% confidence interval (CI) 1.01–1.10; P=0.009) and a 10°C decrease of temperature (RR 1.04, 95% CI 1.02–1.07; P=0.003) were related to an increase in the number of daily deaths. In the male group, a stronger effect of SO2concentration on mortality was noted; the RR for 1-μg/m3 increase of SO2 was 1.10 (95% CI 1.04–1.18; P=0.002). In the subgroup analysis of cardiovascular deaths, the main pollutant that was found to have an effect on daily mortality was PM2.5; the RR for 10-μg/m3 increase of PM2.5 was 1.07 (95% CI 1.02–1.12; P=0.01). Conclusions Air quality and atmospheric conditions had an impact on the mortality of Białystok residents, and this effect was more pronounced in the male population. The main air pollutants that influenced the rate of mortality were SO2and PM2.5. In the female population, an additional factor that influenced the total mortality and mortality due to cardiovascular diseases was temperature. It is worth emphasizing that the impact of SO2 on mortality was clear within “safe” range recommended by WHO. More research on that topic is necessary, but our results bring questions whether the recommended norms should be stricter, or is there a safe concentration of SO2 in the air at all.
