Relationship between air pollution and the number of pneumonia hospitalization in a children's hospital in Changsha / 中南大学学报(医学版)

Objective:To explore the relationship between air pollution and the number of pneumonia hospitalization in a children's hospital in Changsha.Methods:Children who have been in this hospital for the treatment of pneumonia between December 2013 and December 2015 were enrolled in this study.Based on daily meteorological data and air pollution data from December 2013 to December 2015 in Changsha,we constructed a generalized additive model to analyze the relationship between air pollution and the number of pneumonia hospitalization.Results:During the research,the average concentration of PM2.5 and PM10 exceeded the Grade Ⅱ national standards for air quality.The average concentration of SO2 exceeded the Grade Ⅰ national standards.The change of all the 3 main air pollution indexes showed strong statistical relationship with the change of the number of pneumonia hospitalization (P＜0.05),among which,the impact of SO2 ranked number 1,followed by PM2.5 and PM10.Effect of atmospheric pollution on the number of pneumonia boys was basically same as that in the total pneumonia children (P＜0.05).The effect on girls showed no statistical relationship in both models (P＞0.05).Conclusion:The concentrations of SO2'PM2.5 and PM10 are positively correlated with pneumonia hospitalization number of children,and their effect on boys is more obvious than that in the girls.

A Matched Case-Controlled Study of Risk Factors of Nosocomial Pneumonia Caused by Tumor / 中国医师杂志

Objective To study some risk factors of acquired nosocomial pneumonia in tumor case nosocomial infection.Methods 77 tumor case with nosocomial infection were chosen as cases from the patients in hospital for 1:1 case control study.Results It was found that the fatality rate of acquired NP in tumor pattens was 14 3%.Some risk factors of acquired nosocomial infection in tumor case remained significant through logistic regression analysis showed,such as state of an immunosuppression therapy; operation,hospitalization duration,antibiotics application time and mechanical ventilation.Conclusions It was suggested that the iatrogenic pneumonia is comes from multiple risk factors and it should be paid attention. This is the most important step to control nosocomial infection of tumor case in the hospital happen.
