BACKGROUND: Previous studies demonstrated that SAA staining of sarcoidosis granulomas was qualitatively and quantitatively different from other granulomatous diseases. These data suggest that positive SAA staining of granulomatous tissue may have adequate specificity to establish a diagnosis of sarcoidosis. Our objective was to determine the diagnostic specificity of SAA staining for sarcoidosis relative to other granulomatous disorders. METHODS: Pathological specimens demonstrating granulomatous inflammation were retrospectively identified at one institution, plus 4 specimens were obtained from New York City firefighters with biopsy-confirmed World Trade Center "sarcoidosis-like" pulmonary disease...

Hemorrhage is the most preventable cause of post-traumatic death. Many cases are potentially anatomically salvageable, yet remain lethal without logistics or trained personnel to deliver diagnosis or Resuscitative-surgery in austere-environments. Revolutions in technology for remote-mentoring of ultrasound and surgery may enhance capabilities to utilize the skill-sets of non-physicians. Thus, our Research-Collaborative explored remote-mentoring to empower non-physicians to address junctional and torso hemorrhage-control in Austere-environments...

Study Objectives: Firefighters' schedules include extended shifts and long work weeks which cause sleep deficiency and circadian rhythm disruption. Many firefighters also suffer from undiagnosed sleep disorders, exacerbating fatigue. We tested the hypothesis that a workplace-based Sleep Health Program (SHP) incorporating sleep health education and sleep disorders screening would improve firefighter health and safety compared to standard practice. Design: Prospective station-level randomized, field-based intervention...

This study investigated the combined effect of firefighting operations and exposure to smoke on physiological responses, cognitive and physical performance among firefighters. Each firefighter was engaged in two experimental conditions: (1) without artificial smoke; control (NS) and (2) with artificial smoke (WS). The results of data analysis revealed that heart rate (HR) and body temperature (BT) increased significantly after the firefighting activities in the two conditions relative to baseline. In addition, reaction time (RT) and correct response (CR) decreased after the activity relative to baseline and there was a significant difference in RT and CR between the NS and WS conditions...

Posttraumatic stress disorder (PTSD) in emergency service personnel and other trauma-exposed populations is known to be associated with a variety of physical health problems. However, little attention has been paid to the health of ageing emergency service personnel, who may be forced into early medical retirement because of a combination of these issues. Currently employed (N = 274) Australian firefighters completed a cross-sectional survey using validated, self-report measures of PTSD and somatic symptoms...

Firefighting is a stressful occupation. The monitoring of psychophysiological measures in those professionals can be a way to prevent and early detect cardiac diseases and other stress-related problems. The current study aimed to assess morphological changes in the ECG signal induced by acute stress. A laboratory protocol was conducted among 6 firefighters, including a laboratory stress-inducer task - the Trier Social Stress Task (TSST) - and a 2-choice reaction time task (CRTT) that was performed before (CRTT1) and after (CRTT2) the stress condition...

Shift work is associated with diet-related chronic conditions such as obesity and cardiovascular disease. This study aimed to explore factors influencing food choice and dietary intake in shift workers. A fixed mixed method study design was undertaken on a convenience sample of firefighters who continually work a rotating roster. Six focus groups (n = 41) were conducted to establish factors affecting dietary intake whilst at work. Dietary intake was assessed using repeated 24 h dietary recalls (n = 19). Interviews were audio recorded, transcribed verbatim, and interpreted using thematic analysis...

This paper examines elements contributing to the effectiveness of firefighting teams carrying out typical tasks. Fourteen firefighter crews were filmed during nineteen real operations and answered questionnaires relating to psychosocial dimensions. Results have shown that "enriched closed-loops" of communication, positive emotional interactions and a "gamma" type of adaptation are positively related to team effectiveness. Conversely, open and incomplete loops of communication, negative emotional interactions, "beta" and "alpha" types of adaptation are negatively related to team effectiveness...

OBJECTIVES: In a cohort of rescue/recovery workers exposed to the dust that resulted from the collapse of the World Trade Center (WTC), we assessed how a diagnosis of obstructive airways disease (OAD) affected the likelihood of a subsequent diagnosis of chronic rhinosinusitis (CRS) or gastroesophageal reflux disease (GERD). We also assessed whether OAD acted as a mediator of the association between exposure to the WTC rescue/recovery effort and CRS and GERD diagnoses. METHODS: In this prospective cohort study, we analyzed Fire Department of the City of New York physician diagnoses of OAD, CRS, and GERD that were first documented between September 11, 2001, and September 10, 2011, among 8,968 WTC-exposed firefighters...
