Background: Recurring winter smog episodes, recently observed in Poland, have inspired the researches to assess the epidemiological situation concerning the registered exacerbations of respiratory diseases related to worsening of the ambient air quality.
Material And Methods: The model comprising the ecological study results and secondary epidemiological data on registered outpatient visits and hospitalizations in the Silesian voivodeship was used. We assessed the effect of smog observed in January 2017 on the number of acute respiratory disorders registered in that month. Aerosanitary situation was obtained from the Provincial Inspectorate for Environmental Protection in Katowice database.
Results: It was documented that the increase in PM concentration (with simultaneously observed unfavorable meteorological parameters) was related to a higher number of acute respiratory disorders registered daily. Moreover, the increase in the number of outpatient visits due to asthma exacerbation or bronchitis was observed on the first day of episode, and hospitalizations took place with delay of 1-2 days.
Conclusions: The preliminary results indicate the relationship between worsening of ambient air quality during the winter smog and the increase in daily number of registered outpatient visits and hospitalizations due to acute respiratory diseases. Med Pr 2018;69(5):523-530.

A portable gas chromatograph-mass spectrometer (GC-MS) is an effective instrument for rapid on-site detection of volatile organic compounds (VOCs). Current instruments typically adsorb samples at ambient temperature, challenging the detection of low-boiling VOCs. In this study, a low-temperature adsorption thermal desorption method is proposed for sample enrichment in a portable GC-MS.

Background: Chronic obstructive pulmonary disease (COPD) continues to be a significant issue, leading to premature death or reduced quality of life. It's important to assess the current burden of COPD and its risk factors on a geographical basis to guide health policy.
Methods: Data on the prevalence, deaths, and disability-adjusted life years (DALYs) related to COPD, and risk-attributable burden were obtained from the Global Burden of Diseases, Injuries, and Risk Factors Study (GBD) 2021 database.

The impact of O on the respiratory system is a significant global problem. Nevertheless, there is insufficient information about its impact on respiratory disorders in northeast China. In this study, we used a generalized additive model (GAM) to determine the correlation between O concentrations and respiratory deaths based on the daily meteorological data, pollutant concentrations, and respiratory deaths from 2014 to 2016 in Shenyang, a typical city in northeast China.

In the United States (US), neonatal intensive care units (NICUs) monitor and treat newborns for a variety of adverse health concerns including preterm status, respiratory distress and restricted growth. As such, NICU admission is an integrated measure of neonatal risk. We linked 2018 US national birth registry NICU admission data among singleton births with satellite and modelled air pollution levels for the month prior to birth to examine whether late-pregnancy exposure to ambient air pollutants is associated with adverse neonatal health outcomes.
