Observational Study
Impact of crowding in local ambulance demand on call-to-ambulance scene arrival in out-of-hospital cardiac arrest.
Rapid emergency medical service (EMS) response is an important prognostic factor in out-of-hospital cardiac arrest (OHCA). This study aims to evaluate the association between local hourly EMS demand and ambulance response in OHCA. ⋯ Crowding in local ambulance demand was associated with less ambulance dispatched within 1 km and delayed response to the scene in OHCA. Strategies to mitigate and adjust to ambulance demand crowding may be considered for better EMS response performance.

This report describes a case of hemolysis in a patient injecting deoxycholic acid and benzyl alcohol for aesthetic benefit without medical supervision. The concentration and dose injected by the patient resulted in a 10-fold overdose of deoxycholic acid in comparison to the FDA-recommended dosing for the approved indication. Providers should be aware of medically unsupervised use of DCA and other injectables and the potential risks associated with this practice.

To establish and validate a predictive formula for calculating the possibility of developing delayed neurological sequelae (DNS) after acute carbon monoxide (CO) poisoning to facilitate better decision-making about treatment strategies. ⋯ This study established a prediction predictive formula for predicting developing of DNS, which could facilitate better decision-making about treatment strategies.

Myocardial infarctions (MI) have been reported in adults with COVID-19. Although MIs are rare in children with COVID-19, cardiac involvement is still possible. In this case report, we present an adolescent with recent COVID-19 infection who presented with an ECG initially suggestive of myocardial infarction (MI). ⋯ Initial ECGs may show ST-changes suggestive of MI. However, serial ECGs and echocardiograms can differentiate between MI and myocarditis/myopericarditis. Even with COVID-19, MIs are extremely rare in children, and it is important to be aware of MIS-C and its cardiac complications.
