Opis:: Exposure to carbon monoxide is a common hazard in firefighting practice throughout the year, regardless of the winter heating season. Therefore this analysis of the interventions of fire protection units in incidents related to carbon monoxide exposure of a non-fire origin. The objectives include two risk groups: people affected by the intervention and the health risks to fire officers themselves. The analysed material covers the years 2017-2022 and interventions of fire protection units in incidents related to carbon monoxide exposure of a non-fire origin (chemical hazard events). Data from the Decision Support System of the State Fire Service (DSSSFS), provided to the authors by the Operational Planning Office at the Headquarters of the State Fire Service, were used in the study. According to the records of the State Fire Service (SFS) in the years 2017-2022, there were 28,766 (Mean 4794; SD 413) chemical hazard events: carbon monoxide was the cause. There were only 5724 reports of symptoms with a known CO concentration and 1974 reports with clinical symptoms. Statistically significant differences were demonstrated in exposure time (p= 0.028) and average CO concentration in the analysed years (p<0.001). Noteworthy is the sudden reduction in the exposure time following the year 2020. The actual exposure of firefighters to carbonmonoxide is greater than in the above analysis, in addition, there are exposures from fire incidents. Procedures, measuring equipment, and personal protective equipment protect firefighters from absorbing harmful substances into the body, but the large number of incidents and the visible clinical symptoms in victims should prompt firefighters with many years of service to observe even the smallest worrying neurological changes in themselves.

Opis:: Objectives To investigate the effect of CO₂ during sleep on next-morning cognitive performance in young schoolchildren, the authors performed a double-blind fully balanced crossover placebo-controlled study. Material and Methods The authors included 36 children aged 10–12 years in the climate chamber. The children slept at 21°C in 6 groups each at 3 different conditions separated by 7 days in a random order. Conditions were as follows: high ventilation with CO₂ at 700 ppm, high ventilation with added pure CO₂ at 2000–3000 ppm, and reduced ventilation with CO₂ at 2–3000 ppm and bioeffluents. Children were subjected to a digital cognitive test battery (CANTAB) in the evening prior to sleep and on the next morning after breakfast. Sleep quality was monitored with wrist actigraphs. Results There were no significant exposure effects on cognitive performance. Sleep efficiency was significantly lower at high ventilation with CO₂ at 700 ppm which is considered to be a chance effect. No other effects were seen, and no relation between air quality during sleep and next-morning cognitive performance was observed in the children emitting an estimated 10 l CO₂ /h per child. Conclusions No effect of CO₂ during sleep was found on next day cognition. The children were awakened in the morning, and spent from 45–70 min in well-ventilated rooms before they were tested. Hence, it cannot be precluded that the children have benefitted from the good indoor air quality conditions before and during the testing period. The slightly better sleep efficiency during high CO₂ concentrations might be a chance finding. Hence, replication is needed in actual bedrooms controlling for other external factors before any generalizations can be made.

Tytuł:: Beyond complexities of co-operative values and principles: Developing a framework for lifestyle research and education

Opis:: RESEARCH OBJECTIVE: The paper proposes a methodology to study individuals and their institutions by the study of their lifestyles. THE RESEARCH PROBLEM AND METHODS: Following Wojtyla’s methodology of studying the person on the basis of his or her actions and conduct, I decided to use similar methodology to answer the question: Are the 19th century Co‑operative Values and Principles still pertinent in the complex economy of the 21st century, and, if so, how can we operationalise them to become vibrant guidelines not only in contemporary business, but also in improving our everyday lives? THE PROCESS OF ARGUMENTATION: The overview of the research on lifestyle in ethnography, marketing, lifestyle and occupational medicine, and finally criminology shows that unlike values, lifestyle can more easily be operationalized and measured. We both expose our lifestyle and are exposed to the lifestyles of others. Some status‑based lifestyles spread like viruses creating a pandemic of consumerism. These product‑based lifestyles are in complete opposition to the person‑oriented co‑operative lifestyle. RESEARCH RESULTS: An Exposure Model of Lifestyle allows new conceptualization of the isomorphism research. CONCLUSIONS, INNOVATIONS AND RECOMMENDATIONS: The agency based model of lifestyle may be used for constructing diagnostic tools and investigating the very essence of personal motives both in private and work life. This model is supposed to help to investigate to what degree an individual’s lifestyle impacts the functioning of a participative company and whether it is reflected in the company’s success.

Opis:: Objectives: The main goal of the study was to assess possible association between fetal exposure to fi ne particulate matter ($\text{PM}_\text{2.5}$) and exhaled carbon monoxide (eCO) measured in non-asthmatic children. Material and Methods: The subjects include 118 children taking part in an ongoing population-based birth cohort study in Kraków. Personal samplers of $\text{PM}_\text{2.5}$ were used to measure fi ne particle mass in the fetal period and carbon monoxide (CO) in exhaled breath from a single exhalation effort at the age of 7. In the statistical analysis of the effect of prenatal $\text{PM}_\text{2.5}$ exposure on eCO, a set of potential confounders, such as environmental tobacco smoke (ETS), city residence area, sensitization to house dust allergens and the occurrence of respiratory symptoms monitored over the seven-year follow-up was considered. Results: The level of eCO did not correlate with the self-reported ETS exposure recorded over the follow-up, however, there was a positive signifi cant relationship with the prenatal $\text{PM}_\text{2.5}$ exposure (non-parametric trend p = 0.042). The eCO mean level was higher in atopic children (geometric mean = 2.06 ppm, 95% CI: 1.58–2.66 ppm) than in non-atopic ones (geometric mean = 1.57 ppm, 95% CI: 1.47–1.73 ppm) and the difference was statistically signifi cant (p = 0.036). As for the respiratory symptoms, eCO values were associated positively only with the cough severity score recorded in the follow-up (nonparametric trend p = 0.057). In the nested multivariable linear regression model, only the effects of prenatal $\text{PM}_\text{2.5}$ and cough severity recorded in the follow-up were related to eCO level. The prenatal $\text{PM}_\text{2.5}$ exposure represented 5.1%, while children’s cough represented only 2.6% of the eCO variability. Conclusion: Our study suggests that elevated eCO in non-asthmatic children may result from oxidative stress experienced in the fetal period and that heme oxygenase (HO) activity in body tissues may be programmed in the fetal period by the exposure to fi ne particulate matter.
