Identifying Population Groups Based on Humanity Attribution to Low‐, Middle‐ and High‐Socioeconomic Status Groups: A Multilevel Latent Profile Analysis Sainz, Mario; Martínez, Rocío; Muelas Lobato, Roberto Despite growing research on (de)humanisation in the socioeconomic domain, the extent and diversity of these tendencies withinthe population remain unclear. This study used a representative sample of Spaniards (N = 1478) to examine the existence andprevalence of distinct dehumaniser profiles at both the individual (Level 1) and societal (Level 2) levels. We conducted a multi-level latent profile analysis using humanity attribution scores for low-, middle- and high-SES groups. At the individual level, fiveprofiles emerged: high- (12%), middle- (27%) and low- (41%) generalised humanisers, high-SES dehumanisers (6%) and hierarchylegitimisers (13%). At the societal level, we identified three profiles: assimilators (52%), indifferents (7%) and unsettled (41%).Adherence to these profiles appeared to be influenced by participants' socioeconomic backgrounds or system justification andmeritocracy, with profiles differing in their demand for social change. We discuss the applied relevance of mapping dehumani-sation tendencies on the design of targeted interventions.

Promoting Mental Health Support for Adolescents and Future Health Educators Through Nursing‐Led Intervention: A University‐School‐Community Collaboration Model in Spain Alonso Martínez, Laura; San Pedro Arribas, Paula; Sánchez Gutiérrez, María Elena; Zabaleta González, Rebeca; Nieto González, Sandra; Sierra Medina, María José Objective: This study describes a nurse-led intervention aimed at improving mental health literacy (MHL), reducing stigma, andencouraging help-seeking behaviour.Design: A quasi-experimental design involved 578 responses ranging in age from 13 to 52 years (M = 20.28, SD = 6.29), includingsecondary school pupils, nursing undergraduates, and trainee secondary school teachers.Measurements: Pre- and post-intervention assessments examined a wide range of health indicators. These included six scalesassessing mental health knowledge (MHLI), mental health support intentions (MHSSA), body dissatisfaction (EBIC), eatingdisorder risk (SCOFF), problematic pornography use (PPCS-6), and health-protective sexual communication (HPSC). Theintervention focused on reducing stigma, encouraging help-seeking behaviour, and developing practical skills to support peersfacing mental health challenges.Results: Post-intervention results indicated significant improvements in MHL, attitudes, and behavioural intentions across allgroups. Adolescents initially exhibited lower baseline scores than university participants. However, both groups demonstratedsubstantial gains. The most pronounced improvements were observed among women, individuals with prior experience of mentalhealth issues, and university students.Conclusion: This study underscores the vital role of nurses as facilitators in school-based mental health promotion and in theinterdisciplinary education of future health professionals. The nurse-led mental health education into secondary and highereducation curricula foster population-wide mental well-being.

An Efficient, Organic Solvent-Free Method for Extraction and Concentration of Hepatitis E Virus from Pig Liver Santamaría Palacios, Jorge; García, Nerea; Rodríguez Lázaro, David The presence of the hepatitis E virus (HEV) in pork products, particularly in pig liver has been frequently described. However, a standardized method is not still available for the detection of HEV in foods, particularly in those difficult food matrixes such as pig meat and pork products. The aim of this study was to design, optimize and evaluate a new method of food-separation and virus concentration for HEV in pig liver samples. This method is based on organic flocculation and avoids the use of organic solvents. The virus recovery rates and analytical sensitivity of the method using murine norovirus MNV-1 as a surrogate were 73.6–82.2% and at least 1 × 103 TCID50 per g of liver in 100% of the replicates, respectively. Furthermore, this new methodology was validated by testing the presence of HEV RNA in naturally infected pig liver samples, comparing it with two other commonly used concentration methods. The new extraction method run satisfactory in comparison with the two reference methods; statistically equivalent (p < 0.05) to one of the methods used while presented statistically significant better results (p < 0.05) compared to the second method. Consequently, our results indicate that the new extraction method can be an adequate cost-effective and ecologically friendly alternative for the food separation and concentration of HEV RNA in pig liver samples.

Uso de inteligencia artificial generativa para la enseñanza y el aprendizaje de la Naturaleza de la Ciencia en Educación Infantil (FCT-24-21652) Toma, Radu Bogdan; Yánez Pérez, Iraya; Orozco Gómez, Martha Lucía; Queiruga Dios, Miguel Ángel; Soto Muñoz, María Isabel; Rovira Carballido, Jordi La ciencia no es un conjunto de verdades absolutas ni de respuestas definitivas. Es un proceso creativo, colectivo y en constante revisión. Esta serie de cómics, desarrollada por el alumnado del Grado en Maestro de Educación Infantil de la Universidad de Burgos, te invita a descubrir el lado más humano de la investigación: los debates, el escepticismo, los errores y la perseverancia. A través de apasionantes relatos históricos, te sumergirás en los dogmas que desafió la edad de hielo, las rivalidades tras el descubrimiento de Neptuno, el complejo rompecabezas de los continentes en movimiento, o los dilemas éticos de Darwin y la Selección Natural. Una aventura visual para comprender que, detrás de cada teoría, hay personas e historias de superación que transformaron nuestra forma de entender el universo.
