Article Abstract
Introduction: Public knowledge of out-of-hospital cardiac arrest (OHCA), and initiation of basic life support (BLS) is crucial to increase survival in OHCA.
Methods: The study analysed the knowledge and willingness to perform BLS of laypersons passing an AED at a public train station. Interviewees were recruited at two time points before and after a four year-long structured regional awareness campaign, which focused on , , in a mid-size European city (270,000 inhabitants). Complete BLS was defined as multiple responses for ; ; and without mentioning . Minimal BLS was defined as and .
Results: A total of 784 persons were interviewed, 257 at baseline and 527 post-campaign. Confronted with a fictional OHCA, at baseline 8.5% of the interviewees spontaneously mentioned actions for complete BLS and 17.9% post-campaign (p = 0.009). An even larger increase in knowledge was seen in minimal BLS (34.6% vs 60.6%, p < 0.001).
Conclusion: After a regional cardiac arrest awareness campaign, we found an increase in knowledge of BLS actions in the lay public. However, our investigation revealed severe gaps in BLS knowledge, possibly resulting in weak first links of the chain of survival.

Background: Cardiopulmonary resuscitation (CPR) is a vital intervention for managing cardiac arrest; however, enhancing survival rates remains a significant challenge. Recent advancements highlight the importance of integrating artificial intelligence (AI) to overcome existing limitations in prediction, intervention, and post-resuscitation care.
Methods: A thorough review of contemporary literature regarding AI applications in CPR was undertaken, explicitly examining its role in the early prediction of cardiac arrest, optimization of CPR quality, and enhancement of post-arrest outcomes.

Targeted temperature management (TTM) is currently the only potentially neuroprotective intervention recommended for post-cardiac arrest care. However, there are concerns among the scientific community regarding conflicting evidence supporting this recommendation. Moreover, the bulk of trials included in systematic reviews that inform guidelines and recommendations have been conducted in developed countries, with case mix and patient characteristics that significantly differ from the reality of developing countries such as Brazil.

Endotracheal intubation is a critical medical procedure for protecting a patient's airway. Current intubation technology requires extensive anatomical knowledge, training, technical skill, and a clear view of the glottic opening. However, all of these may be limited during emergency care for trauma and cardiac arrest outside the hospital, where first-pass failure is nearly 35%.

Importance: Lower survival rates among Black adults relative to White adults after in-hospital cardiac arrest are well-described, but these findings have not been consistently replicated in pediatric studies.
Objective: To use a large, national, population-based inpatient database to evaluate the associations between in-hospital mortality in children receiving cardiopulmonary resuscitation (CPR) and patient race or ethnicity, patient insurance status, and the treating hospital's proportion of Black and publicly insured patients.
Design, Setting, And Participants: This retrospective population-based cohort study used the Healthcare Cost and Utilization Project Kids' Inpatient Database (1997-2019 triennial versions).

Background And Aims: Fulminant myocarditis (FM) is a complex clinical syndrome characterized by acute myocardial inflammation and cardiogenic shock. Evidence on long-term outcomes, mortality risk factors, and targeted treatment options remains limited.
Methods: This retrospective analysis included consecutive adult patients admitted for FM between January 2012 and November 2022 at 26 European tertiary centres.
