“…[57] Warm temperature (>13.5 C) was associated with increased hospital admissions for ischemic and hemorrhagic stroke during short-term exposure to PM 2.5 , PM2.5–10 and PM 10 individually. [58] Increased NO 2 exposure is positively associated with stroke admissions during the cold season in Wuhan, China, where air pollution concentrations are 50% greater in the winter. [59]…”

The purpose of this review is to describe recent clinical and epidemiological studies examining the adverse effects of urban air pollution on the central nervous system (CNS). Air pollution and particulate matter (PM) are associated with neuroinflammation and reactive oxygen species (ROS). These processes affect multiple CNS pathways. The conceptual framework of this review focuses on adverse effects of air pollution with respect to neurocognition, white matter disease, stroke, and carotid artery disease. Both children and older individuals exposed to air pollution exhibit signs of cognitive dysfunction. However, evidence on middle-aged cohorts is lacking. White matter injury secondary to air pollution exposure is a putative mechanism for neurocognitive decline. Air pollution is associated with exacerbations of neurodegenerative conditions such as Alzheimer’s and Parkinson’s Diseases. Increases in stroke incidences and mortalities are seen in the setting of air pollution exposure and CNS pathology is robust. Large populations living in highly polluted environments are at risk. This review aims to outline current knowledge of air pollution exposure effects on neurological health.

“…Increased risk of cardiovascular disease, including stroke, linked to the exposure to ambient concentrations of air pollutants has been documented increasingly in recent years [ 1 , 2 , 3 , 4 , 5 ]. The effects of the exposure to different air pollutants on the morbidity and mortality of cardiovascular diseases have been presented [ 2 , 6 , 7 , 8 ].…”

Data on the association between air pollution and risk of ischemic stroke in China are still limited. This study aimed to investigate the association between short-term exposure to ambient air pollution and risk of ischemic strokes in Guangzhou, the most densely-populated city in south China, using a large-scale multicenter database of stroke hospital admissions. Daily counts of ischemic stroke admissions over the study years 2013-2015 were obtained from the Guangzhou Cardiovascular and Cerebrovascular Disease Event Surveillance System. Daily particulate matter <2.5 µm in diameter (PM 2.5 ), sulfur dioxide (SO 2 ), nitrogen dioxide (NO 2 ), ozone (O 3 ), and meteorological data were collected. The associations between air pollutants and hospital admissions for stroke were examined using relative risks (RRs) and their corresponding 95% confidence intervals (CIs) based on time-series Poisson regression models, adjusting for temperature, public holiday, day of week, and temporal trends in stroke. Ischemic stroke admissions increased from 27,532 to 35,279 through 2013 to 2015, increasing by 28.14%. Parameter estimates for NO 2 exposure were robust regardless of the model used. The association between same-day NO 2 (RR = 1.0509, 95% CI: 1.0353-1.0668) exposure and stroke risk was significant when accounting for other air pollutants, day of the week, public holidays, temperature, and temporal trends in stroke events. Overall, we observed a borderline significant association between NO 2 exposure modeled as an averaged lag effect and ischemic stroke risk. This study provides data on air pollution exposures and stroke risk, and contributes to better planning of clinical services and emergency contingency response for stroke.

“…A 10 µg/m 3 decrease in concentration would imply 256 less hospital admissions and savings of approximately R$ 220,000 in a medium-sized city [15]. Other studies also show the connection between particulate matter and hospital admissions due to stroke as well as between children pneumonia and air pollution [16,17]. Certain pollution is associated with elevated hospital admissions due to respiratory diseases and ischemic stroke [18,19].…”

The purpose of this article is to analyse the correlation of air quality data with the number of emergency medical interventions and the number of patient visits to emergency clinic of the Integrated Emergency Hospital Admission (Croatian acronym: OHBP).The analysis was conducted on data regarding Slavonski Brod (Croatia) from 1 January to 31 August 2016, obtained from: (1) System eHitna -emergency medical services interventions (2) Patients' visit to OHBP-General Hospital Slavonski Brod (3) Environmental Protection Agency data regarding air quality for PM2.5, PM10 and H 2 S per day. The number of interventions ranged from 103 to 260 (M = 151), and the number of patients from 90 to 250 per day (M = 133). Overall the number of interventions was 37,482, and overall number of patients 32,757. The values of PM2.5 ranged from 1.73 to 500.11 µg/m 3 (M = 18.70), values of PM10 ranged from 3.17 to 520.21 µg/m 3 (M = 25.55), and values of H2S ranged from 0.62 to 12.43 µg/m 3 (M = 1.49).The values of PM2.5, PM10 and H2S have been analysed also depending on the limit values (25 µg/m 3 for PM2.5, 50 µg/m 3 for PM10 and 5 µg/m 3 for H2S).The values were within the limit values for PM2.5 in 64% of days, in 80% of days for PM10 and in 93% of days for H2S.There was a statistically significant weak correlation (r S = 0.333, p < 0.05) between PM2.5 and the number of patients per day, weak correlation (r S = 0.334, p < 0.05) between PM10 and the number of patients per day and a weak correlation (r S = 0.171, p < 0.05) between H2S and the number of patients per day.There was a statistically significant difference in the number of patients who were provided with medical assistance in the day depending on the values of PM2.5 (p < 0.001) and PM10 (p < 0.001), while for H2S the significance was borderline (p = 0.051).
