Objective: This study aims to assess effects of noise on physicians' stress levels and attention capacities within an emergency department.
Methods: In this prospective cross-sectional study, 15 physicians from a state hospital emergency department with 300,000 annual visits provided demographics, work factors, and physiologic data. Attention was evaluated through smartphone-based Stroop tests, while noise and heart rates were monitored via smartwatches.
Results: Median physician age was 26, with 16 months' emergency department experience. Average sound intensity was 68.80 dB. Despite noise, physicians in green/yellow areas showed increased Stroop scores (p = 0.002). Heart rate responses correlated with noise changes. End-of-shift surveys highlighted physicians' adaptability and resilience to high noise levels.
Conclusion: Noisy emergency departments pose health risks to physicians, but noise-related stress did not significantly affect attention, beneficial for patient care.

While autonomic dysregulation and repolarization abnormalities are observed in subarachnoid hemorrhage (SAH), their relationship remains unclear. We aimed to measure skin sympathetic nerve activity (SKNA), a novel method to estimate stellate ganglion nerve activity, and investigate its association with electrocardiogram (ECG) alterations after SAH. We recorded a total of 179 SKNA data from SAH patients at three distinct phases and compared them with 20 data from controls.

Background: Research demonstrates that Point-of-care ultrasound (POCUS) improves clinical outcomes for patients. Improving clinician satisfaction with POCUS should promote utilization into everyday practice, leading to improved clinical outcomes. Despite this benefit, there are still barriers to use including POCUS workflow.

Monkeypox virus (MPXV) is an enclosed, double-stranded DNA virus from the Orthopoxvirus genus, which also contains variola, vaccinia, and cowpox. MPXV, which was once confined to West and Central Africa, has recently had a rebound, spreading beyond its original range since 2017. The virus is distinguished by its unique morphology, which includes an oval or brick-shaped structure and a complex lipid and protein makeup.

Background: The one health (OH) approach, linking human, animal, and environmental health, relies on effective community engagement (CE), education, stewardship, and effective regional and global partnerships. For real impact, communities should be at the centre of research agenda setting and program implementation. This review aimed at synthesizing empirical evidence on how communities are involved in one health research.

Although Emergency Medicine is now globally an established specialty, the Nordic countries have been relatively slow to implement it into their health care systems. To facilitate the development of EM in the Nordic area, a working group was formed with representation from all national EM societies; DASEM (Danish Society for Emergency Medicine), FiSEM (Finnish Society of Emergency Medicine), ISEM (Icelandic Society for Emergency Medicine), NCEM (Norwegian College of Emergency Medicine), and SWESEM (Swedish Society for Emergency Medicine). This group was tasked with creating a Nordic EM manifesto-to create a definition and developmental goals for Nordic Emergency Medicine.
