Objectives: Severe loneliness poses a significant risk to older adults’ health and quality of life. Thisstudy assessed the psychometric properties (reliability and validity) of the Portuguese version of theALONE scale in community-dwelling older adults and explored the scale’s associations with sociode-mographic, social isolation, depression, life satisfaction, and daily functioning.Method: A descriptive, correlational study was conducted with 285 Portuguese older adults. Thequestionnaire included sociodemographic and health data, the ALONE scale, Social Isolation Scale(SIS), Satisfaction with Life Scale (SWLS), Geriatric Depression Scale (GDS-15), UCLA Loneliness Scale(UCLA-16), and Lawton and Brody IADL Scale. Analyses included confirmatory factor analysis, internalconsistency, group comparisons, correlations, and logistic regression.Results: The confirmatory factor analysis supported a unidimensional model with satisfactory fitindices and internal consistency (α = 0.743). Severe loneliness correlated positively with social isolationand depression and negatively with life satisfaction and daily functioning. Participants experiencingsevere loneliness were likely older, female, living alone, socially isolated, depressed, and dependentin daily activities. Significant predictors included social isolation (OR = 0.806) and depression (OR =1.131).Conclusion: The ALONE scale demonstrated validity and reliability for assessing loneliness in olderadults, making it a suitable, efficient tool for clinical practice.
Strategic Communication: Journalists’ Role Amid the Rise in Digital Influencers
Publication . Arriscado, Paula; Campos Sobreira, Rosa Maria
Journalists have a long-standing presence in strategic communication, seen as a “transitory” mediating stakeholder that can influence other key audiences within organizations. However, their role is increasingly being challenged by the rise in alternative information disseminators—mainly digital influencers (DIs) who possess considerable persuasive power and command extensive reach across diverse audiences. Using a qualitative methodology, this study aims to analyze the perceptions of brand and strategic communication professionals regarding the role of journalists in the context of the emergence of influencer marketing within the field of strategic communication. To this end, the views of 24 communication professionals were gathered, including individuals from communication agencies and communication departments in both public and private sector organizations. The findings were discussed in light of the conceptual framework of media relations and digital influence. Results indicate that, although DIs are now well-established within the field of strategic communication, their rise has not diminished the importance of journalists in communication strategies.
Literacia em saúde e a ansiedade no perioperatório : intervenções do enfermeiro especialista
Publication . Figueiredo, Vera Lúcia Silveira; Antunes, Ricardo
A literacia em saúde é um determinante crítico dos resultados clínicos e emocionais, influenciando a forma como a pessoa compreende, integra e utiliza informação sobre o processo cirúrgico em contexto perioperatório. Este relatório tem como objetivo desenvolver e analisar as competências especializadas do enfermeiro em enfermagem médico-cirúrgica, na área do perioperatório, e estudar a relação entre a literacia em saúde e a ansiedade, identificando as intervenções do Enfermeiro Especialista.
Foi realizado um estágio clínico de 360 horas em Bloco Operatório e Unidade de Cirurgia de Ambulatório de uma Unidade Local de Saúde, articulando a aquisição de competências de especialista e de mestre, através do desenvolvimento de um estudo quantitativo, correlacional e transversal. A amostra de conveniência integrou 285 adultos em situação perioperatória, avaliados através de um questionário constituído por uma parte sociodemográfica, da versão portuguesa da HLSQ16 e do STAI-Y. A recolha decorreu no período pré-operatório, antes da consulta de Enfermagem, e os dados recolhidos foram alvo de análise estatística.
Os resultados mostraram que 68,7% dos participantes apresentavam literacia suficiente e excelente, e níveis de ansiedade pré-operatória moderados. Verificou-se uma associação negativa estatisticamente significativa entre literacia em saúde e ansiedade de estado e de traço.
Conclui-se que a literacia em saúde é um determinante modificável da ansiedade perioperatória, o que justifica a sua avaliação sistemática na consulta de Enfermagem pré-operatória e o investimento em estratégias educativas personalizadas. O percurso de estágio permitiu consolidar competências técnicas, científicas, éticas e de liderança, reforçando o papel do Enfermeiro Especialista como agente de mudança na promoção da literacia, na prevenção da ansiedade e na melhoria contínua da qualidade dos cuidados em contexto perioperatório.

Social network analysis in football: a systematic review of performance and tactical applications
Publication . Alves, Ricardo; Dias, Gonçalo Nuno Figueiredo; Nunes, Nuno André; Querido, Sérgio M.; Vaz, Vasco
Introduction:This systematic review aims to critically examine the application of social network analysis (SNA) in football, with a focus on its contribution to evaluating team performance, tactical behavior, and player interactions. Methods: Following PRISMA guidelines, a comprehensive search was conducted across four databases (PubMed, Scopus, Web of Science, and SPORTDiscus) from January 2017 to October 2024. Results: Fifty-five peer-reviewed studies met the inclusion criteria, addressing network analysis in official men's professional football matches. Data were extracted and summarized regarding methodological quality, network metrics used, tactical context, and practical implications.
Discussion: Most studies demonstrated that cohesive network structures, characterized by high density, clustering coefficients, and centrality, are associated with successful team performance. Centrality metrics were frequently used to identify key tactical players, typically central defenders and midfielders. Recent methodological advances included dynamic time-window analysis, pitch-passing networks, and spatial-temporal integration using tracking data. However, there remains an overrepresentation of elite men's football and offensive phases, with limited focus on defensive networks, youth categories, and women's football. SNA offers a powerful framework to decode the complexity of football performance, evolving from static graphs to dynamic, rolesensitive, and context-rich models. Future research should adopt longitudinal designs, multi-layer network approaches, and closer collaboration with practitioners to enhance the operational utility of network insights in coaching and performance analysis.Systematic review registration: https://osf.io/2pe3y
