“…Specifically, higher concentrations of NO 2 and SO 2 prior to hospital admission were a significant risk factor for hospital admissions. However, no association with CO, O 3 , and PM 10 was found, unlike what has been seen in other studies on the general population [17,21–25,50]. This fact could be due to the limited sample size of our group of HIV-infected patients.…”

The aim of our study was to evaluate the seasonal variations and whether short-term exposure to environmental risk factors, such as climate and air pollution, is associated with PTB-related hospital admissions in human immunodeficiency virus (HIV)-infected patients in Spain during the era of combined antiretroviral therapy (cART). A retrospective study was carried out using data from the Minimum Basic Data Set (MBDS) and the State Meteorological Agency (AEMET) of Spain. The primary outcome variable was hospital admissions with PTB diagnosis. The environmental risk factors evaluated were season, temperature, humidity, NO2, SO2, O3, PM10, and CO. Overall, HIV-infected patients had a lower frequency of PTB-related hospital admissions in summer (22.8%) and autumn (22.4%), but higher values in winter (26.6%) and spring (28.2%). Using a Bayesian temporal model, PTB-related hospital admissions were less frequent in summer-autumn and more abundant in winter-spring during the first years of follow-up. During the later years of follow-up, the seasonal trends continued resulting in the lowest values in autumn and the highest in spring. When considering short-term exposure to environmental risk factors, lower temperatures at 1 week (odds ratio (OR) = 1.03; p = 0.008), 1.5 weeks (OR = 1.03; p<0.001), 2 weeks (OR = 1.04; p<0.001), and 3 weeks (OR = 1.03; p<0.001) prior to PTB admission. In addition, higher concentration of NO2 at the time of admission were significantly associated with higher likelihoods of PTB-related hospital admission in HIV-infected patients when 1.5 weeks (OR = 1.1; p = 0.044) and 2 weeks (OR = 1.21; p<0.001) were used as controls. Finally, higher concentration of SO2 at 1.5 weeks prior to PTB admission was significantly associated with a higher likelihood of PTB-related hospital admissions (OR = 0.92; p = 0.029). In conclusion, our data suggest an apparent seasonal variation in hospital admissions of HIV-infected patients with a PTB diagnosis (summer/autumn vs. winter/spring), as well as a link to short-term exposure to environmental risk factors, such as temperature and ambient NO2 and SO2.

“…In this study, among of all the ambient air pollutants, SO 2 contributed to the lowest concentrations and prolong exposure was significantly associated with PTB. Our findings were consistent with other study in South Korea showing the role of SO 2 in TB infection despite we did not stratified the SO 2 exposure by sex [20]. However, the study in South Korea found only men were susceptible to TB in relation to SO 2 exposure [20].…”

Introduction: The possible impact of ambient air pollution exposure on the development of active tuberculosis (TB) remains obscure. This study investigated the potential role of ambient air pollution in activating pulmonary TB (PTB) compared to extrapulmonary TB (EPTB). Materials and Methods: Data on TB cases were obtained from national surveillance data in Malaysia during 2013 and air pollution data were obtained from 52 air-monitoring stations around the country for the 3-year period of 2011-2013. Analyses were performed to estimate the odds of PTB vs. EPTB with changes in the 3-year (2011-2013) average Air Pollutant Index (API) and specific ambient air pollutants. Results: Results showed that the 95th-percentile of API levels during 2011-2013 was moderate and it was not associated with PTB. However, the odds of active PTB compared to EPTB was significantly elevated with the 95th-percentile levels for particulate matter with an aerodynamic diameter of 10 μm or less (aOR = 1.006, 95% CI: 1.002, 1.011), p-value < 0.01, and sulfur dioxide (aOR = 1.012, 95% CI: 1.006, 1.019), p-value < 0.01. Conclusions: These results provide suggestive evidence of the effects of ambient air pollution on development of active pulmonary TB compared to extrapulmonary TB. Additional research on the impacts of ambient air pollution on TB is warranted.

“…Outdoor air pollution has been known as one of the risk factors that affect human health directly and/or indirectly [1][2][3][4]. In Korea, it is reported that long-term exposure to ambient air pollution has a reasonable association with tuberculosis, cardiovascular diseases, and preterm delivery [5][6][7]. Thus, periodic monitoring and management of air pollution are required for exposure assessment for effective health management.…”

Time-Series Mapping of PM₁₀Concentration Using Multi-Gaussian Space-Time Kriging: A Case Study in the Seoul Metropolitan Area, Korea

This paper presents space-time kriging within a multi-Gaussian framework for time-series mapping of particulate matter less than 10 m in aerodynamic diameter (PM 10 ) concentration. To account for the spatiotemporal autocorrelation structures of monitoring data and to model the uncertainties attached to the prediction, conventional multi-Gaussian kriging is extended to the space-time domain. Multi-Gaussian space-time kriging presented in this paper is based on decomposition of the PM 10 concentrations into deterministic trend and stochastic residual components. The deterministic trend component is modelled and regionalized using the temporal elementary functions. For the residual component which is the main target for space-time kriging, spatiotemporal autocorrelation information is modeled and used for space-time mapping of the residual. The conditional cumulative distribution functions (ccdfs) are constructed by using the trend and residual components and space-time kriging variance. Then, the PM 10 concentration estimate and conditional variance are empirically obtained from the ccdfs at all locations in the study area. A case study using the monthly PM 10 concentrations from 2007 to 2011 in the Seoul metropolitan area, Korea, illustrates the applicability of the presented method. The presented method generated time-series PM 10 concentration mapping results as well as supporting information for interpretations, and led to better prediction performance, compared to conventional spatial kriging.
