Mild traumatic brain injuries with loss of consciousness are associated with increased inflammation and pain in military personnel.

Mild traumatic brain injuries (mTBI) are a pervasive concern for military personnel. Determining the impact of injury severity, including loss of consciousness (LOC) may provide important insights into the risk of psychological symptoms and inflammation commonly witnessed in military personnel and veterans following mTBI. US military personnel and veterans were categorized into three groups; TBI with LOC (n = 36), TBI without LOC (n = 25), Controls (n = 82). Participants reported their history of mTBI, psychological symptoms (post-traumatic stress disorder [PTSD] and depression), health-related quality of life (HRQOL), and underwent a blood draw. ANCOVA models which controlled for insomnia status and combat exposure indicated that both mTBI groups (with/without LOC) reported significantly greater depression and PTSD symptoms compared to controls; however, they did not differ from each other. The mTBI with LOC did report greater pain than both controls and mTBI without LOC. The TBI with LOC group also had significantly elevated IL-6 concentrations than both TBI without LOC and control groups. Within the mTBI groups, increased TNFα concentrations were associated with greater PTSD symptoms. These findings indicate that sustaining an mTBI, with or without LOC is detrimental for psychological wellbeing. However, LOC may be involved in perceptions of pain and concentrations of IL-6.

Resumen La exposición a material biológico es el más frecuente de los riesgos que corren los trabajadores de la salud, y enconsecuencia los estudiantes del internado rotatorio. El presente estudio propone el análisis de las características de los accidentes producidos por contacto con material biológico en alumnos del Internado Rotatorio de la carrera de Medicina de la Facultad de Medicina de la UNNE.Estudio descriptivo retrospectivo de corte transversal en base a las declaraciones de los alumnos que sufrieron exposición accidental a sangre y fluidos. De 400 cursantes, 25 denunciaron accidente laboral. Con mayor frecuencia se produjeron en Servicios de Emergencias, lesiones de tipo punzocortantes y contacto con sangre. Como medida de bioseguridad exclusiva se utilizaron guantes. La mayor parte de los encuestados desconocía las pautas postexposición. La mayoría de los estudiantes notificó el hecho, pero gran parte no tomó medidas al respecto. La toma de muestras para serología fue mínima, y el porcentaje de estudiantes que recibió tratamiento quimioprofiláctico post exposición fue aún menor. Por todo ello creemos fundamental insistir con diferentes estrategias en la concientización a los alumnos,jerarquizando la prevención y las pautas a seguir en caso de producirse el accidente.

Summary Exposure to biological material is the most frequent risk for the health workers, and the rotating internship studentstoo. This study proposes the review of characteristics of accidents caused by contact with biological material in studentscoursing what we call “Internado Rotatorio” at the UNNE School of Medicine.Retrospective descriptive study of cross-section based on statements by students who suffered accidental exposureto blood and other fluids.Among 400 students, 25 reported work- accidents. This event happened most frequently in Emergency Services, bysharp and contact with blood-like lesions. They used gloves as the exclusive biosecurity measure. Most of the studentsreported the fact, but not all of them took any action in this regard. Sampling for serology was minimal, and thepercentage of students receiving prophylaxis post exposure treatment was even lower. Because of this, we believe essentialto insist with different strategies awareness to students, structuring prevention and guidelines to be followedin case of this kind of accident.

La exposição a material biológico é o mais frequente dos riscos para dos trabalhadores da saúde estão expostos e, portanto,os alunos de estágio rotativo. O presente estudo propõe uma análise das características dos acidentes causadospor contato com material biológico em alunos do internato rotativo da Carreira Médica da faculdade de Medicinada UNNE.Estudo descritivo retrospectivo de secção baseado em declarações de estudantes que sofreram exposição acidentala sangue e fluidos. De 400 alunos, 25 relatou acidentes relacionados com o trabalho. Com mais freqüência ocorreuem serviços de emergência, afiada e contato com sangue, como lesões. Luvas foram usadas como medida de biossegurançaexclusiva. A maioria dos entrevistados sabem padrões pós-exposição. A maior parte dos estudantes relatouo fato, mas não tomaram nenhuma medida nenhuma ação quanto a isso. Amostragem de serologia era mínima, e apercentagem de alunos recebem tratamento de exposição do quimioprofiláctico post foi ainda menor.É por isso que consideramos essenciais para insistir com consciência de estratégias diferentes para estudantes, estruturaçãode prevenção e orientações a seguir em caso de acidente.
