“…Our results suggest that older adults should pay more attention to protective measures against air pollution. Wearing protective masks and staying indoors are two effective methods [ 62 – 64 ]. However, some studies have found opposite results, indicating that younger people are more affected by air pollution [ 65 ].…”

Background Angina is a crucial risk signal for cardiovascular disease. However, few studies have evaluated the effects of ambient air pollution exposure on angina. Objective We aimed to explore the short-term effects of air pollution on hospitalization for angina and its lag effects. Methods We collected data on air pollutant concentrations and angina hospitalizations from 2013 to 2020. Distributed lag nonlinear model (DLNM) was used to evaluate the short-term effects of air pollutants on angina hospitalization under different lag structures. Stratified analysis by sex, age and season was obtained. Results A total of 39,110 cases of angina hospitalization were included in the study. The results showed a significant positive correlation between PM2.5, SO2, NO2, and CO and angina hospitalization. Their maximum harmful effects were observed at lag0-7 (RR = 1.042; 95% CI: 1.017, 1.068), lag0-3 (RR = 1.067; 95% CI: 1.005, 1.133), lag0-6 (RR = 1.078; 95% CI: 1.041, 1.117), and lag0-6 (RR = 1.244; 95% CI: 1.109, 1.397), respectively. PM10 did not have an overall risk effect on angina hospitalization, but it did have a risk effect on women and the elderly. O3 was significantly negatively correlated with angina hospitalization, with the most pronounced effect observed at lag0-6 (RR = 0.960; 95% CI: 0.940, 0.982). Stratified analysis results showed that women and the elderly were more susceptible to pollutants, and the adverse effects of pollutants were stronger in the cold season. Conclusion Short-term exposure to PM2.5, SO2, NO2, and CO increases the risk of hospitalization for angina.

“…The N95 respirator mask protects against a range of particulate matter, such as dust, fumes, aerosols, smoke, pollen, mould spores, bacteria, and viruses (CDPH, 2022). Research has shown that wearing an N95 can help lessen respiratory symptoms (Tultrairatana & Phansuea, 2021). Not all N95 respirators meet international standards for effectiveness and safety.…”

Research Objective This study aimed to examine influential voices recommending N95 respirators during a peak in cases and deaths. Our study sought to understand whether influencers were providing accurate details about the correct type of N95 that would protect the wearer and those around them and the vital need to ensure a proper fit for the N95. Study Design Our study drew upon primary data from Twitter and retrieved n = 251,740 tweets from January 2021, which were filtered and analysed using social network analysis. The study drew upon mixed methods. Betweenness centrality was used to identify influential users recommending N95 face masks. A coding frame was developed to determine whether complete advice was provided. The tweets received as replies to each of the influencers were analysed using content analysis. Principal Findings Our study found that the most influential users recommending about N95 face masks were medical professionals and public health experts. Moreover, our data revealed that most tweets by health influencers recommending N95s did not provide further details about the correct type of N95 mask and the vital need to ensure a proper fit for the mask. Implications for Policy and Practice Healthcare influencers can play a vital role in disseminating accurate and timely information. Our study confirmed that prominent health influencers were not providing enough information about N95s. We produce three key recommendations for healthcare influencers. Our results are likely to be of interest to health services and for improving patient safety.

“…Epidemiological evidence has been provided for the human respiratory system [13][14][15]. Due to their size [16,17], short-term and long-term exposures [18,19] of ambient PM 2.5 cause more adverse health effects and toxicity than PM 10 [20][21][22]. Ambient PM 2.5 can easily move through the human body inhalation pathway.…”

This study evaluates low-cost sensors (LCSs) for measuring coarse and fine particulate matter (PM) to clarify and measure air pollution. LCSs monitored PM10, PM2.5 (fine particulates), and PM1.0 concentrations at four sites in Samutprakarn, Thailand from December 2021 to April 2022. Average daily PM10, PM2.5, and PM1.0 concentrations at the monitoring locations were 53–79, 34–45, and 31–43 μg/m3, respectively. In December 2021, the monitoring station had a daily PM2.5 value above 100 μg/m3, indicating haze occurrences. However, the monitoring site’s daily PM10 and PM1.0 concentrations did not surpass Thailand’s ambient air quality threshold. We also measured and calibrated comparative particulate matter concentrations from LCSs and a tapered element oscillating microbalance (TEOM) monitor (Pollution Control Department (PCD) standard analytical method). PM2.5 concentrations from the LCSs were lower than TEOM, but the difference was not statistically significant. The PM2.5 monitoring station provided near-real-time air quality data for health risk reduction, especially when PM levels were high. Based on this study, authorities and local agencies may consider improving air quality regulation in Samutprakan, focusing on suburban PM2.5 air pollution.
