We investigated if the phenotypic classification of acute heart failure (AHF) based on the number of signs/symptoms of congestion and hypoperfusion at emergency department (ED) arrival identifies subgroups in which intravenous (IV) nitroglycerine (NTG) use improves short-term survival. ⋯ Phenotypical classification of AHF based on congestion/hypoperfusion at ED arrival does not identify subgroups of patients in whom IV-NTG would decrease mortality, although it could potentially be beneficial in those with LVEF of less than 50%. This hypothesis will have to be confirmed in the future. Conversely, our results suggest that IV-NTG may be harmful in patients with only mild clinical congestion.

Body temperature is considered an independent determinant of respiratory rate and heart rate; however, there is limited scientific evidence regarding the association. This study aimed to assess the association between temperature, and heart rate and respiratory rate in children. ⋯ In this study on children attending urgent and emergency care settings, there was an independent association between temperature and heart rate but not between temperature and respiratory rate.

Helicopter emergency medical services (HEMS) allow for shorter transport duration in long-distance evacuations and facilitate advanced en-route medical care access. Studies comparing HEMS with ground emergency medical services (GEMS), including the outcome of prehospital mortality, are lacking. ⋯ HEMS was not associated with a decrease in early mortality among trauma casualties in this study encompassing the prehospital and hospital scenes. There was a positive trend and a decrease in mortality from penetrating injuries. Further research to ascertain which casualties benefit from HEMS is warranted and will allow for more precise use of this expensive resource.

Observational Study
Early chest CT-scan in emergency patients affected by community-acquired pneumonia is associated with improved diagnosis consistency.
Chest CT-scan (CT) exceeds chest X-ray (CXR) to diagnose community-acquired pneumonia (CAP) but actual use and results remain unclear. We examine whether CT performed at ED visit improved ED diagnosis of CAP as compared to a final diagnosis of CAP at hospital discharge (gold standard diagnosis for the study), and how it impacts relevant clinical outcomes. This retrospective monocenter observational study was based on the analysis of the hospital database. ⋯ In patients admitted after ED, CT improved diagnosis consistency for CAP [88.2% vs. 80.9%; difference 7.3% (95% confidence interval 1.2-13.3%)] with a trend for lower hospital length-of-stay [10.2 vs. 12.2 days; difference -2.0 (95% confidence interval -3.9 to -0.1)], but not ICU admission ( P = 0.09) and in-hospital mortality ( P = 0.056). Diagnosis of patients admitted with CAP improved when CT was obtained at ED visit. These results should be reproduced at a larger scale to test whether early CT conserves healthcare resources.
