Determining the underlying etiology of syncope provides valuable prognostic information and expedites the implementation of a therapeutic strategy. This study aimed to evaluate the ability of Canadian Syncope Risk Score (CSRS) in differentiating cardiogenic and non-cardiac syncope. ⋯ The present study reveals that CSRS has fair accuracy in differentiating the source of syncope and has no superiority over a clinical examination. Therefore, we do not recommend relying on the CSRS to differentiate between cardiac and non-cardiac syncope alone.

Unintentional injury remains the leading cause of death for adults worldwide. We aimed to investigate the rates and distribution of dead on arrival (DOA) patients according to emergency medical services (EMS) mode of transport (MoT), EMS transport time (TT), injury severity score (ISS), and type of injury. ⋯ Helicopter emergency medical service use with intermediate and severely injured patients with penetrating injuries is associated with a reduced number of DOAs. Future studies should prospectively investigate EMS performance to confirm the findings identified in this retrospective analysis. Additionally, other factors affecting pre-hospital EMS performance (e.g., geographic variations, weather-related characteristics, in-flight interventions/procedures) should be investigated. Finally, the results of this study highlight the need for standardized HEMS utilization triage criteria.

QRS duration predicts outcomes in cardiac arrest survivors undergoing therapeutic hypothermia.
Whether the electrocardiography (ECG) serial changes predict outcomes in cardiac arrest survivors undergoing therapeutic hypothermia remains unclear. ⋯ In cardiac arrest survivors given therapeutic hypothermia, QRS durations at the ROSC, after rewarming and their changes may predict survival to hospital discharge.

To investigate how the total prehospital time (TPT), Abbreviated Injury Scale (AIS), Injury Severity Score (ISS), and Trauma Score-Injury Severity Score (TRISS) affect the outcome of plane crash victims from anatomical, physiological and psychological perspectives. The accuracy or strength of these scores and TPT in predicting hospitalization and surgery, sequelae development and psychiatric complications [permanent temporary disability (PoTDs)] and PTSD can allow medical professionals to direct and prioritize management efforts of the victims of mass casualties in general. ⋯ It is expected that everyone who practices medicine be equipped to handle multiple casualties. As the number of people involved in mass casualties increases, diagnostic tools, workups such as laboratory and radiological studies, and prognostic markers such as trauma scores should be simpler and more user-friendly.

The outcomes of patients with cardiac arrest induced by non-traumatic hemorrhagic cardiac tamponade are poor. ⋯ Based on the results of preliminary study, we hypothesized that invasive medical intervention for patients with cardiac arrest induced by non-traumatic hemorrhagic cardiac tamponade might be useful for obtaining return of spontaneous circulation and a survival outcome, especially for patients with witnessed collapse with PEA as the initial rhythm.
