Association between Ambient Air Pollution and Hospital Emergency Admissions for Respiratory and Cardiovascular Diseases in Beijing: a Time Series Study

Objective To investigate the association between ambient air pollution and hospital emergency admissions in Beijing. Methods In this study, a semi-parametric generalized additive model （GAM） was used to evaluate the specific influences of air pollutants （PM10, SO2, and NO2） on hospital emergency admissions with different lag structures from 2009 to 2011, the sex and age specific influences of air pollution and the modifying effect of seasons on air pollution to analyze the possible interaction. Results It was found that a 10μg/m3 increase in concentration of PMlo at lag 03 day, SO2 and NO2 at lag 0 day were associated with an increase of 0.88%, 0.76%, and 1.82% respectively in overall emergency admissions. A 10 lag/m3 increase in concentration of PM10, SO2 and NO2 at lag 5 day were associated with an increase of 1.39%, 1.56%, and 1.18% respectively in cardiovascular disease emergency admissions. For lag 02, a 10 μg/m3 increase in concentration of PM10, SO2 and NO2 were associated with 1.72%, 1.34%, and 2.57% increases respectively in respiratory disease emergency admissions. Conclusion This study further confirmed that short-term exposure to ambient air pollution was associated with increased risk of hospital emergency admissions in Beijing.

Diurnal Temperature Range and Daily Emergency Room Admissions among the Elderly in Beijing,China

In recent years, more attentions have been paid to the association between climate change and human health. Increasing and more variable global surface temperature is one of the key climatic change factors which have been consistently reported about the effect on human health. So far, more researches have revealed that temperature lead not only to direct deaths and illnesses but also to aggravation of cardiovascular and respiratory diseases. Typically, the relationship between temperature and mortality or morbidity is V-, U-, or J- shaped, with optimum temperature corresponding to the lowest point in the temperature mortality curve.

Emergency Department Admissions for Dental &Oral Health Concerns in Rural Northwestern Pennsylvania

Background: Oral health emergency department (ED) visits are increasing nationally. This increase in ED admissions is an indicator that preventative dental and oral healthcare practices are not being utilized. Methods: Data was obtained from the Meadville Medical Center. Fourteen ICD-9 codes for dental and oral health admissions over 10 years were categorized and analyzed. Data was graphed to illustrate trends over time and the chi-square test of independence was used to determine associations between admissions types and demographic characteristics. Results: ED admissions for dental and oral health issues were most common among individuals age 19 - 38 years. Most individuals admitted to the ED for these concerns paid with private medical insurance or were uninsured. The categorization of ICD-9 codes allowed us to see that ED use for structural and soft-issues decreased at the end of the decade under study. However, admissions for infections and dental caries increased over time. Conclusions: The opening of a free dental clinic in 2011 might be associated with the decrease in overall admissions for dental and oral health concerns as well as soft tissue and structural admissions. The increase in ED admissions for dental caries and infections illustrates that more affordable and preventative dental and oral health care and education are need.
