With the introduction of mobile applications that allow short-term rentals, electric scooters (e-scooters) are gaining popularity as a means of micromobility in urban areas. The aim of the study was to assess the circumstances and causes of death in traffic accidents involving electric scooters in Poland. The inclusion criteria for the study were met by 9 cases (7 M,2F; mean age: 40.3 years). ⋯ The most common cause of death was craniocerebral injury (6/9 cases), but there were two deaths each from chest injuries and polytrauma. To increase the safety of e-scooter users, it is recommended that measures be taken to educate users about the potential risks of using the vehicle and that measures be taken to increase the use of helmets, e.g. through legislative action. Further studies involving larger study groups are needed to assess the correlation between potential risk factors and the fatal outcome of the accident.

Observational Study
Prediction of Time to Hemodynamic Stabilization of Unstable Injured Patient Encounters Using Electronic Medical Record Data.
Background : This study sought to predict time to patient hemodynamic stabilization during trauma resuscitations of hypotensive patient encounters using electronic medical record (EMR) data. Methods: This observational cohort study leveraged EMR data from a nine-hospital academic system composed of Level I, Level II, and nontrauma centers. Injured, hemodynamically unstable (initial systolic blood pressure, <90 mm Hg) emergency encounters from 2015 to 2020 were identified. ⋯ In-hospital mortality was highest at Level I, 3.0% vs. 1.2% at Level II, and 0.3% at nontrauma centers ( P < 0.001). Importantly, nontrauma centers had the highest retriage rate to another acute care hospital (12.0%) compared to Level II centers (4.0%, P < 0.001). Conclusion: Time to stabilization of unstable injured patients can be predicted with EMR data.

Impact of Surgical Team Involvement at the Time of Trauma Activation for Pediatric Patients With Motorized Cycle or All-Terrain Vehicle Injury Mechanism.
At our institution, level 2 trauma (L2T) activations are primarily managed by pediatric emergency medicine (PEM) physicians, whereas level 1 activations are co-managed by pediatric surgery and PEM. Starting in September 2019, the response to L2T activations due to all-terrain vehicles or motorized cycles (ATVs/MCs) changed to include surgical assessment upon patient arrival due to increased likelihood of significant injuries and need for higher level of care. The impact of PEM/surgery co-management of ATV/MC L2T patients on time to an admission decision is unknown. ⋯ Early surgical assessment for pediatric patients with ATV/MC injuries improved time to an admission decision and trauma communication huddle compliance. Next steps include identifying process improvement opportunities to decrease ED total length of stay for patients with ATV/MC injuries.

Patients with traumatic out-of-hospital cardiac arrest (t-OHCA) require on-scene airway management to maintain tissue oxygenation. However, the benefits of prehospital endotracheal intubation remain unclear, particularly regarding neurological outcomes. Therefore, this study aimed to evaluate the association between prehospital intubation and favourable neurological outcomes in patients with t-OHCA. ⋯ Prehospital intubation was associated with favourable neurological outcomes among adult patients with t-OHCA who had severe chest injury or transportation time >15 min.

Objective : Vascular endothelial cells (ECs) sense and respond to both trauma factors (histone proteins) and sepsis signals (bacterial lipopolysaccharide, LPS) with elevations in calcium (Ca 2+ ), but it is not clear if the patterns of activation are similar or different. We hypothesized that within seconds of exposure, histones but not LPS would produce a large EC Ca 2+ response. We also hypothesized that histones would produce different spatio-temporal patterns of Ca 2+ events in veins than in arteries. ⋯ Exposure of ECs to histones or LPS both increased gene expression, but different mRNAs were induced. Conclusions : LPS and histones activate ECs through mechanisms that are distinct and additive; only histones produce large aberrant Ca 2+ events. ECs in arteries and veins display different patterns of Ca 2+ responses to histones.
