"Leo&Giulia standing for public health": an animated series to promote the values of public health among school-aged children. Best practices and field-trial protocol.

Background: The "Leo&Giulia standing for public health" project is an innovative digital health education model targeting primary school children. The project, developed during the COVID-19 pandemic, aims to educate primary school-aged children about public health issues through an animated cartoon series. It highlights the importance of early-life health promotion and the potential role of educational settings in shaping health behaviours. Study design: A 2-year school-based cluster-randomized controlled community trial will be conducted among 8-10-year-old pupils in the province of Pavia, Northern Italy. Methods: The intervention group will receive an educational programme via a new episode of "Leo&Giulia" animated series, focusing on smoking prevention. The study will assess changes in knowledge, attitudes towards smoking, and communication about smoking risks among peers and parents. The trial involves baseline and follow-up assessments through questionnaires targeting both children and parents. Results (expected): We assume that children in the intervention group will demonstrate increased knowledge and awareness of smoking-related health risks and develop negative attitudes towards tobacco use compared to the control group. Enhanced communication about tobacco harms among peers and between children and parents, as well as increased parental involvement in anti-smoking socialization practices, are expected secondary outcomes. Discussion and Conclusions: "Leo&Giulia" integrates health education into the school curriculum, leveraging the appeal of animated content to engage children in public health topics. The project is expected to contribute to the field of health education by demonstrating the effectiveness of digital health interventions in childhood, foreseeing potential long-term impacts on health behaviors and in shaping future public health strategies.

Out-of-hospital cardiac arrest outcomes' determinants: an Italian retrospective cohort study based on Lombardia CARe.

This study on the Lombardia Cardiac Arrest Registry (Lombardia CARe,) the most complete nationwide out-of-hospital cardiac arrest (OHCA) registry in Italy, aims at evaluating post-OHCA intra-hospital mortality risk according to patient's characteristics and emergency health service management (EMS), including level of care of first-admission hospital. Out of 12,581 patients included from 2015 to 2022, we considered 1382 OHCA patients admitted alive to hospital and survived more than 24 h. We estimated risk ratios (RRs) of intra-hospital mortality through log-binomial regression models adjusted by patients' and EMS characteristics. The study population consisted mainly of males (66.6%) most aged 60-69 years (24.7%) and 70-79 years (23.7%). Presenting rhythm was non-shockable in 49.9% of patients, EMS intervention time was less than 10 min for 30.3% of patients, and cardiopulmonary resuscitation (CPR) was performed for less than 15 min in 29.9%. Moreover, 61.6% of subjects (n = 852) died during hospital admission. Intra-hospital mortality is associated with non-shockable presenting rhythm (RR 1.27, 95% CI 1.19-1.35) and longer CPR time (RR 1.39, 95% CI 1.28-1.52 for 45 min or more). Patients who accessed to a secondary vs tertiary care hospital were more frequently older, with a non-shockable presenting rhythm and longer EMS intervention time. Non-shockable presenting rhythm accounts for 27% increased risk of intra-hospital death in OHCA patients, independently of first-access hospital level, thus demonstrating that patients' outcomes depend only by intrinsic OHCA characteristics and Health System's resources are utilised as efficiently as possible.
