ABSTRACT Military personnel, firefighters, and fire survivors exhibit a higher prevalence of mental health conditions such as depression post‐traumatic stress disorder (PTSD) compared to the general population. While numerous studies have examined neurological impacts physical trauma psychological stress, research on acute neurobehavioral effects gas inhalation from explosions or fires is limited. This study investigates early‐stage neuronal consequences explosion in Sprague–Dawley rats. Rats were exposed simulated explosive subsequently assessed using behavioral tests neurobiological analyses. The high‐dose exposure group demonstrated significant depression‐like behaviors, including reduced mobility exploration. However, damage was not evident histological Immunofluorescence revealed increased density radial glia oligodendrocytes specific brain regions, suggesting hypoxia axon induced by potential mechanism for observed changes. These findings underscore impact health, highlighting habenula dentate gyrus hippocampus possible target regions. are expected support early diagnosis treatment strategies injuries caused gas, offering insights into intervention PTSD affected populations.

This study aims to assess the effect of psychosocial risks and resources on burnout, psychosomatic disorders, job satisfaction using Hierarchical Regression Modelling (HRM) Qualitative Comparative Analysis (QCA).The sample consisted 9020 non-university public education teachers (Mage = 45.33 years, SD 9.15; 72.5% women).Demands variables (Workload, Emotional labour, Imbalance, Interpersonal conflict) were better predictors than (Job autonomy, Social support, Resources at work). also significantly improved model's predictive capacity, except in case Indolence. In QCA results, none conditions seems be necessary. Regarding sufficiency, combination different explains between 44-49% high levels Burnout 40-47% low Burnout; 44-47% Psychosomatic disorders disorders; 49% Job 45-56% levels.The results show that models have explanatory capacity HRM. Some not significant HRM, but they present with other model variables. The findings contribute understanding how affect workers' health satisfaction.

Firefighting is recognised as a profession where health and well-being can be affected by variety of occupational factors, such physical, thermal, chemical stressors. Along with the risks intuitively associated fire service, however, psychosocial stress has begun to attract attention another variable deserving consideration. Indeed, long-term exposure work-related been linked poor outcomes in many workers; despite this association, very little done examine how stressors become biologically embedded firefighters. To help facilitate research into affect health-related we propose framework centered on notion allostatic load. First, reviewed characteristics that may generate within firefighters before introducing load (that is, dysregulation across various physiological systems caused need manage ongoing stressors). Next, provided summary measured touched framework's utility for studying cumulative effects firefighter health. After this, factors influence steps leading from were discussed; particular, commented upon area should consider specific non-modifiable (age, sex, ethnicity) modifiable (psychosocial resources behavioural habits) factors. Finally, presented methodological barriers opportunities arise when using professional group. By framework, hope provide tool used those interested stress-health build evidence needed inform primary prevention measures.

In the complex work environments of firefighting teams, it is often human error or difficulties in teamwork that lead to dangerous situations. To prevent these, essential know teamwork-related stressors and resources operations. A measurement tool needed evaluate these resources. successive instrument development process was conducted identify relevant First, interviews with experienced firefighters, second, a document analysis were evaluated provide an overview Thereupon, questionnaire, REST-Q Fire, developed asking about frequency intensity identified Afterwards, online study firefighters ( N = 491). CFAs confirmed assumed structure Fire positive correlation stress shown r .19 - .27). Further, overall more frequently intensively perceived than stressors. The most important ‘behavior leaders’ M (SD) 2.80 (0.83), 3.59 (1.12)), team members’ 2.77 (0.75), (1.05)). resources, on other hand, ‘knowledge skills behavior 3.96 (0.63), 4.24 (0.78)), ‘watch out for/ check each other’ (0.70), 4.20 (0.80)), ‘reliability (0.51), 4.16 (0.73)). As result, training needs for trainees fire service derived.
