Multicenter Study Observational Study
Injury patterns and mortality associated with near-hanging in children.
The pathophysiology of near-hanging in children is different from that of adults due to anatomic, physiologic, and injury-related mechanisms, with evidence suggesting that blunt cerebrovascular injuries (BCVI) and cervical spine injuries (CSI) are uncommon. We sought to estimate the incidence of secondary injuries and their association with mortality in pediatric near-hanging victims. ⋯ In this multi-center study of pediatric near-hanging victims, BCVI and CSI occurred rarely and were not associated with mortality. While children in our study underwent neck imaging more frequently than head imaging, cerebral edema occurred more often than other injury types and imparted the highest mortality risk. Given the rarity of BCVI and CSI, a selective approach to neck imaging may be warranted in pediatric near-hanging events.

The predictive value of the respiratory rate‑oxygenation (ROX) index for a high-flow nasal cannula (HFNC) in patients with COVID-19 with acute hypoxemic respiratory failure (AHRF) may differ from patients without COVID-19 with AHRF, but these patients have not yet been compared. We compared the diagnostic accuracy of the ROX index for HFNC failure in patients with AHRF with and without COVID-19 during acute emergency department (ED) visits. ⋯ The ROX index had an acceptable discriminative power for predicting HFNC failure in patients with AHRF with and without COVID-19 in the ED. However, the higher ROX index thresholds than those in previous publications involving intensive care unit (ICU) patients suggest the need for careful monitoring and establishment of a new threshold for patients admitted outside the ICU.

Prediction of the neurological outcomes post-cardiac arrest: A prospective validation of the CAST and rCAST.
The neurologic prognosis of out-of-hospital cardiac arrest (OHCA) patients in whom return of spontaneous circulation (ROSC) is achieved remains poor. The aim of this study was to externally and prospectively validate two scoring systems developed by us: the CAST score, a scoring system to predict the neurological prognosis of OHCA patients undergoing targeted temperature management (TTM), and a simplified version of the same score developed for improved ease of use in clinical settings, the revised CAST (rCAST) score. ⋯ rCAST showed high predictive accuracy for the neurological prognosis of OHCA patients managed by TTM, comparable to that of the oCAST score. The scores on the rCAST were strongly correlated with the neurological functions at 90 days, implying that the rCAST is a useful scale for assessing the severity of brain injury after cardiac arrest.

Recent work has demonstrated that children with unintentional cannabis ingestions often undergo extensive ancillary testing such as head imaging or lumbar puncture. To better understand the yield of these tests, our objective was to describe the frequency of additional significant diagnoses in children with cannabis ingestion. ⋯ In children with cannabis intoxication, high rates of head imaging and lumbar puncture are likely driven by the signs of altered mental status at presentation. These data suggest that if cannabis ingestion is considered early and identified quickly with testing, neuroimaging, particularly that with ionizing radiation, may be low yield.

Observational Study
Lack of patient and primary care physician follow-up in geriatric emergency department patients with head trauma from a fall.
Falls are the leading cause of injuries in the US for older adults. Follow-up after an ED-related fall visit is essential to initiate preventive strategies in these patients who are at very high risk for recurrent falls. It is currently unclear how frequently follow-up occurs and whether preventive strategies are implemented. Our objective is to determine the rate of follow-up by older adults who sustain a fall related head injury resulting in an ED visit, the rate and type of risk assessment and adoption of preventive strategies. ⋯ Only 60% of ED patients with fall-related head injury follow-up with their PCP. Further, 72% received a fall assessment and only 56% adopted a fall prevention strategy. These data indicate an urgent need to promote PCP fall assessment and adoption of prevention strategies in these patients.
