A global perspective on gun violence injuries.

INTRODUCTION AND DEFINITIONS: Civilian gunshot violence is a growing public health issue on a global scale. Treatment of patients with gunshot injuries is based on algorithms derived from military studies, but the distinct differences in weaponry, energy of injury, timing and type of care, and environment translate to a gap in knowledge. With a focus on non-accidental gunshot trauma and excluding suicide etiologies, we propose to build a collaborative research group to address important questions focused on best practices for gunshot injury patients. PRE-HOSPITAL CARE: There are important differences in the care of gunshot victims across the globe; some countries provide advanced interventions in the field and others deliver basic support until transport to a higher level of care in hospital. Some simple interventions include the use of extremity tourniquets and intravenous fluid support; others to consider are tranexamic acid, whole blood, and hemostatic agents. ACUTE TREATMENT: Control of exsanguinating hemorrhage is a key priority for gunshot injuries. Military doctrine has evolved to prioritize exsanguination over airway or breathing as the critical first step. The X-ABC protocol focuses on exsanguinating hemorrhage, then standard evaluation of Airway, Breathing and Circulation (ABCs) to enhance survival in trauma patients. The timing of bony stabilization, in terms of damage-control vs definitive care, needs further study in this population, as does use of antibiotics for bony extremity injuries. Finally, recognition of the mental health effects of gun trauma, including post-traumatic stress disorder (PTSD), anxiety disorders, substance abuse and depression is important in advocating for prevention such as implementation of social support and specific interventions. DEFINITIVE CARE: The need for abdominal closure after exploratory laparotomy, definitive fracture treatment, and other treatment all contribute to length of stay for gunshot injured patients. Optimizing stabilization allows earlier mobilization and decreases nosocomial complications. Nerve injuries are often a source of long-term disability and their evaluation and treatment require further investigation. RESOURCES AND ETHICS: There are growing numbers of mass-casualty gunshot events, which require consideration of how to organize and use resources for treatment, including staff, operating room access, blood products, and order of treatment. Drills and planning for incident command hierarchy and communication are key to optimizing resource utilization. The ethics of choosing treatment priorities and resources are important considerations as well.

An ecological approach to clinically assess nightmares in military service members with severe PTSD.

BACKGROUND: Trauma-related nightmares (TRNs) are distressing events which contribute to insomnia severity, chronicity and treatment resistance of PTSD. Therefore, recording TRNs is a crucial technical challenge in order to understand their physiopathological patterns and their impact on sleep. However, TRNs are difficult to record during a single night in a sleep laboratory, which, moreover, is likely to be considered by patients as a protective sleep environment that is therefore not representative of home sleep conditions. METHOD: In the present study, we investigate if objective sleep measures acquired at-home using two ambulatory devices is of clinical value by correlating with PTSD patients' complaints about sleep and nightmares. A secondary objective is to relate awakenings associated with TRNs to sleep stages and to provide new insights into the use of electrodermal activity (EDA) as a potential physiological marker of TRNs. Sixty veterans and active-duty service members were assessed by questionnaires and recorded for 5 consecutive nights in their homes. RESULTS: Our approach firstly identified positive correlations between subjective and objective sleep parameters (total sleep time, sleep-onset latency and TRNs frequency). We also developed a method of synchronization between the two ambulatory devices that allowed us to match 200 TRNs (reported by event marker push button) with sleep stages corresponding to 91 nights and 37 patients. Most awakenings associated with TRNs occurred during NREM sleep (65.5% versus 34.5% during REM sleep). Our results also reveal significant differences in the frequency of EDA peaks 10 min before the reported events, with a lower frequency in REM (13.7 peaks) than in NREM (24.8 peaks) awakenings associated with TRNs. This EDA peaks frequency in REM sleep is not statistically different from that in REM sleep preceding awakenings that are not associated with TRNs. CONCLUSION: The development of wearable devices to collect physiological parameters is of interest in clinical practice to improve our knowledge of sleep and trauma-related nightmares in patients with PTSD.

[Clinical approach to post-traumatic stress disorders]. / Clinique des états de stress post-traurmatiques.

A confrontation with death can lead to acute reactions of stress, followed possibly, after a phase of latency, by post-traumatic stress disorder (PTSD). PTSD is characterised by the appearance of a repetition syndrome combining reliving, hypervigilance and avoidance; comorbidities frequently arise, increasingthe risk of suicide. Caregivers have an important role to play in identifying them.

[Rehabilitation and reintegration of soldiers injured on deployment]. / Réadaptation et réinsertion des militaires blessés en operation.

The participation of the French army in the Afghan conflict has highlighted the need for discussion and action regarding the pathway, rehabilitation and reintegration of soldiers who have been physically or psychologically injured. Clinical experience demonstrates that difficulties are less likely to appear during the initial treatment phase than later on, when there is less group support and there are fewer visible effects of the recognition on the part of the institution. It is important to strengthen the links between healthcare personnel and institutional players, in order to optimise the medical and social care of these war casualties.

Mortality among active-duty male French Armed Forces, 2006-10.

BACKGROUND: In the Armed Forces, knowledge about the causes of deaths is required in order to develop prevention strategies. This study presents the main characteristics of causes of deaths among male active-duty personnel in the French Armed Forces during the 2006-10 period and compares them with the general French male population. METHODS: The data are provided by military public health surveillance. Comparisons of the specific mortality rates (MR) were performed using a Poisson regression. Standardized mortality ratios (SMRs) were calculated to compare mortality with the general French male population. RESULTS: There were 1455 deaths among male active-duty personnel during the study period [MR: 100.9 per 100,000 person-years (PY); 95% confidence interval 95.7-106.1]. The 17-24 age group was characterized by violent deaths: transport accident (MR: 45.9 per 100,000 PY) and suicide (18.8 per 100 000 PY). Overall SMRs show significantly lower MR compared with the French national MR with the exception of SMR for transport accident and suicide in the 17-24 age group. CONCLUSIONS: There is a significantly lower deficit of mortality compared with the French male general population, reflecting a strong healthy worker effect. However, health promotion programmes should continue to put emphasis on transport accident especially among the 17-24 age group.
