Introduction: COVID-19 provoked a myriad of challenges for people’s health, poor life satisfaction and an unhealthy diet that could be associated with serious negative health outcomes and behaviours. University is a stressful environment that is associated with unhealthy changes in the eating behaviours of students. The association between diet and mental health is complex and bidirectional, depending on the motivation to eat; emotional eaters regulate their emotions through the increased consumption of comfort foods. Objective: The aim of this study was to compare the nutritional habits, alcohol consumption, anxiety and sleep quality of female health science college students. Material and methods: A cross-sectional study of 191 female undergraduate students in Madrid was used. Their body mass index and waist hip ratio were measured. The questionnaires used included the Mediterranean Diet Adherence test, AUDIT, Emotional Eater Questionnaire, Pittsburgh Sleep Quality Index, and Food Addiction, Perceived Stress Scale and STAI questionnaires. Results: We observed a high intake of protein, fat, saturated fatty acids and cholesterol. Overall, 9.5% never had breakfast, and 66.5% consciously reduced their food intake. According to Pittsburgh Sleep Quality Index, they mainly slept 6–7 h, and 82% presented with a poor sleep quality; 13.5% presented moderate–high food addiction, and 35% had moderate Mediterranean Diet Adherence score. Conclusion: Female students’ macronutrient imbalances were noted, with a high-level protein and fat intake diet and a low proportion of carbohydrates and fibre. A high proportion of them need alcohol education and, depending on the social context, they mainly drank beer and spirits.

Background: Oxidative stress (OS) is a key biological mechanism influencing surgical recovery, contributing to impaired healing, infectious complications, cardiovascular events, and mortality. This umbrella review aimed to synthesize evidence from systematic reviews and meta-analyses exclusively focused on the relationship between validated oxidative stress biomarkers and postoperative outcomes. Narrative and non-systematic reviews were excluded. Methods: A comprehensive search of PubMed, Scopus, and Web of Science was conducted on 15 March 2024 and updated on 12 December 2024 to identify systematic reviews and meta-analyses including adult surgical patients, validated oxidative stress biomarkers, and clinical outcomes. Methodological quality was evaluated with AMSTAR 2 and ROBIS. The SANRA checklist was used only to verify that narrative or bibliometric reviews did not meet the inclusion criteria. These non-systematic reviews were excluded from the synthesis and cited solely as contextual references. Findings: From 527 records, ten systematic reviews of moderate to high methodological quality were included, encompassing approximately 230 primary studies. The most frequently reported biomarkers were total antioxidant capacity (TAC), glutathione (GSH), superoxide dismutase (SOD), malondialdehyde (MDA), and 8-hydroxy-2′-deoxyguanosine (8-OHdG). Lower TAC, GSH, and SOD levels were consistently associated with poor recovery and multiorgan dysfunction, whereas elevated MDA and 8-OHdG levels correlated with infectious complications, delayed healing, cardiovascular events, persistent pain, and mortality. Antioxidant-based interventions such as vitamin C, N-acetylcysteine, and propofol showed heterogeneous but promising effects, particularly in high-risk surgical populations. The main limitations were the heterogeneity of biomarkers, variability in perioperative protocols, and partial overlap of primary evidence across reviews. Interpretation: The findings were organized into three main clinical domains: (1) infectious complications and impaired healing; (2) cardiovascular and systemic complications; and (3) predictive and prognostic value of OS biomarkers for perioperative risk assessment. This thematic synthesis integrates evidence across different surgical specialties, highlighting consistent mechanistic patterns and key research gaps to inform future investigations and clinical decision-making.

Introducción: Evaluar las competencias es una cuestión de importancia que ocupa un lugar primordial en el contexto de la educación superior. Para ello, es necesario disponer de instrumentos que reúnan criterios de validez y fiabilidad, y que puedan ser utilizados en escenarios de desempeño, capacidad y actuación profesional. Por esta razón, nos planteamos el siguiente objetivo: determinar la concordancia intra e interobservador de una escala para la evaluación de competencias enfermeras (ECOEnf) en España. Material y método Estudio observacional, descriptivo y transversal para evaluar la fiabilidad mediante el análisis de concordancia intra e interobservadores de la escala «ECOEnf». Se utilizó la prueba no paramétrica Tau-b de Kendall para establecer la correlación, aplicada a la misma población, en el mismo tiempo, por 2 observadores diferentes. Resultado: La concordancia intraobservador se obtuvo una excelente consistencia interna (r = 0,98). Respecto a la concordancia entre observadores se mostraron escasos ítems con una correlación menor de 0,5; sin embargo, todos los ítems cumplen con una buena fiabilidad, estadísticamente significativa, p valor < 0,05. Conclusión: En general, al realizar la correlación entre los resultados de la herramienta medido 2 veces por diferentes observadores en el mismo momento se encontró estadísticamente una buena concordancia, por lo cual se considera un instrumento fiable para ser utilizado en la evaluación de las competencias enfermeras en España. Introduction: Competences assessment is an important issue, playing a key role in higher education. It is necessary to have an evaluation instrument that meet validity and reliability criteria and can be used in different clinical scenarios for professional performance measurement. For this reason, we set ourselves the following objective: Establishing the intra- and inter-observer concordance of a scale for the evaluation of nursing competencies (ECOEnf) in Spain. Material and method An observational, descriptive, cross-sectional study was conducted to evaluate the reliability of the “ECOEnf” scale using intra- and inter-observer analysis. Kendall's Tau-b non-parametric test was used for establishing correlation, applied to the same population, at the same time, by 2 different observers. Results: Intra-observer concordance was obtained an excellent degree of internal consistency (r=0.98), Regarding inter-observer concordance, few items had a correlation lower than 0.5. However, all items display a sound statistically significant reliability with a p-value <0.05. Conclusion: In general, when establishing the correlation between the results of the instrument measured twice by different observers at the same time, was found a statistically good concordance. For this reason, it is regarded as a reliable instrument to be used in the evaluation of nursing competencies.

Resumen Objetivo: en su carácter de profesión de atención de la salud enfocada en cuidar a las personas, la Enfermería requiere habilidades de comunicación sólidas. Sobre la base de un consenso internacional de expertos, se presenta una propuesta sobre resultados de aprendizaje en la comunicación clínica para planes de estudio de las carreras de grado de Enfermería en países de habla hispana. Método: un comité orientador, compuesto por 5 enfermeros y expertos en comunicación en ciencias de atención de la salud, elaboró la primera lista de habilidades de comunicación específicas para la carrera de Enfermería. Un comité de 7 asesores científicos internacionales revisó y mejoró dicha propuesta. Se seleccionó a 70 expertos de 14 países a través del procedimiento de muestreo “bola de nieve”, y se los invitó a participar en un proceso de consenso Delphi modificado a distancia en dos rondas de encuesta. Se realizó un análisis estadístico para establecer el nivel de consenso final correspondiente a cada ítem. Resultados: se presentó un cuestionario con 68 resultados de aprendizaje en comunicaciones clínicas para que lo evaluara el panel. En la primera ronda Delphi, el panel llegó a un consenso estadístico en todos los ítems evaluados. No fue necesaria una segunda ronda para conciliar posiciones. Conclusión: se presenta una propuesta académica, aprobada con un elevado nivel de consenso internacional, a fin de orientar y unificar los resultados de aprendizaje en los planes de estudio sobre comunicación clínica para carreras de grado de Enfermería en países de habla hispana.

Aim: To identify the primary nursing diagnoses and interventions related to patients with chronic kidney disease undergoing renal replacement therapy, organised according to Marjory Gordon's functional health patterns through a scoping review.Methods: A scoping review was conducted following the JBI 2020 Guidelines and the PRISMA ScR extension. Articles published between 2014 and 2021 were included from the Web of Science, Scopus and PubMed databases. The search strategy utilised DeCS and MeSH descriptors with Boolean operators AND/OR. Articles in English and Spanish authored by nurses and featuring retrospective, prospective or cross‐sectional designs were selected. After extracting the main diagnoses and interventions, a nominal group of nephrology experts discussed the findings, followed by a Delphi technique to achieve consensus.Results: A total of nine studies were included, eight from Brazil and one from Turkey, which reflects a possible geographic concentration bias. Fifty‐five nursing diagnoses and seventy‐six core interventions were identified and categorised into Marjory Gordon's 11 functional patterns, facilitating the structuring of nursing action fields in nephrology.Conclusions: This review established a set of standardised nursing interventions specific to patients with chronic kidney disease undergoing renal replacement therapy. Implications for health policies: The classification supports the organisation of nephrology units, reduces professional overload and enhances care quality and patient safety. The standardised taxonomy (NANDA, NIC, NOC) facilitates interdisciplinary communication and promotes advanced nursing practice.No Patient or Public Contribution: The study is a review of already published scientific articles and a review of experts and researchers who contributed to the document. For this reason, an express declaration of the patient, user or caregivers is not required since there was no participation in the study.
