COVID-19 Pandemic–Related Reductions in Pediatric Asthma Exacerbations Corresponded with an Overall Decrease in Respiratory Viral Infections
2022, Journal of Allergy and Clinical Immunology: In PracticeCitation Excerpt :Consistent with our previous publication that studied the early phases of the pandemic,23 we did not observe changes to levels of air pollutants that diverged from historical trends; that is, seasonal variability in PM2.5, PM10, and ozone, which peaked during summer 2020, and NO2, which peaked during winter 2020, was consistent with 2015-2019 trends.43,44 Similarly, seasonal peaks were observed among aeroallergens from April to June and early September, according to pollen type,11,45 but these changes were consistent with historical trends. Previously, we explicitly confirmed that the seasonal decrease in levels of 4 air pollutants in the 2-month period following Philadelphia’s first lockdown period was not statistically significant when compared with historical trends via interrupted time series analysis.23
Allergenic Pollen Season Variations in the Past Two Decades Under Changing Climate in the United States
2021, Immunology and Allergy Clinics of North AmericaCitation Excerpt :Increasing duration of ragweed pollen season in North America has been correlated to latitude and thus warming temperatures. The increase in surface temperature has not been uniform all over, rather has been more toward the poles or with increase in altitude.40 Since 1995, the ragweed pollen season has been longer by 13 days to 27 days at latitudes above 44°N. Ziska and colleagues12 collected and analyzed data pertaining to ragweed pollen as collected by NAB in in the United States and Aerobiology Research Laboratories in Canada.
Heavy precipitation and asthma exacerbation risk among children: A case-crossover study using electronic health records linked with geospatial data
2020, Environmental ResearchCitation Excerpt :These data were measured on Broad Street in Center City of Philadelphia, on most weekdays during the allergy season each year (roughly mid-March through October). The Asthma Center station is the only National Allergy Bureau (NAB)-certified pollen and mold counter for Philadelphia and sampling is conducted in accordance with the standards outlined by the American Academy of Allergy, Asthma, and Immunology (AAAAI) (Dvorin et al., 2001). We used conditional logistic regression models to compare case days to control days.
