Both suicidality and alcohol use disorders are significant public health concerns among firefighters, and alcohol use is associated with increased suicide risk. In addition, firefighters endorse high rates of symptoms of depression and posttraumatic stress disorder (PTSD). Thus, the current investigation examined associations between alcohol dependence and suicide risk among a large sample of firefighters. Specifically, this study examined the indirect effects of alcohol dependence on suicidality outcomes via both depression and posttraumatic stress, using structural equation modeling...

The objective of this study was to review the incidence of skin allograft discard and bacterial contamination due to donor bioburden at the Ontario Professional Firefighters Skin Bank over a 14-year period. We sought to determine whether modifications to our prerecovery donor preparation process have been effective in reducing skin bioburden and identify other potential risk factors of allograft contamination. A retrospective review of all skin donors (n = 259) processed from 2002 to 2015 was performed. Multivariate logistic regression was used to determine whether donor-related factors and procurement-related factors were significantly associated with microbial contamination predisinfection and discard secondary to contamination...

Aqueous film-forming foams (AFFF) containing poly- and perfluoroalkyl substances (PFAS) used for firefighting have led to the contamination of soil and water at training sites. The unique physicochemical properties of PFAS results in environmental persistency, threatening water quality and making remediation of such sites a necessity. This work investigated the role of sorbent amendment to PFAS contaminated soils in order to immobilise PFAS and reduce mobility and leaching to groundwater. Soil was sampled from a firefighting training facility at a Norwegian airport and total and leachable PFAS concentrations were quantified...

Physical work and sleep loss are wildland firefighting demands that elicit psychological and physiological stress responses. Research shows that these responses are statistically related which presents an opportunity to use subjective psychological questionnaires to monitor physiological changes among firefighters; an approach used extensively in sport settings. The aim of the present study was to investigate if changes in self-reported psychological factors on the multi-component training distress scale (MTDS), relate to cytokines and cortisol levels among firefighters completing three days of simulated physical firefighting work separated by an 8-h or restricted 4-h sleep each night...

Wildfires are one of the main environmental problems facing societies today, and in the case of Galicia (north-west Spain), they are the main cause of forest destruction. This paper used binary structured additive regression (STAR) for modelling the occurrence of wildfires in Galicia. Binary STAR models are a recent contribution to the classical logistic regression and binary generalized additive models. Their main advantage lies in their flexibility for modelling non-linear effects, while simultaneously incorporating spatial and temporal variables directly, thereby making it possible to reveal possible relationships among the variables considered...
