Background and objectives: The incidence of breast cancer worldwide has increased in recent decades, accounting for 1 in 3 neoplasms in women. Besides, nurses are mainly represented by the female collective, most of them, undertaking working conditions with intensive rotative and night shifts due to the 24-h pace of work of this profession. The objective of this study was to assess the possible relationship between shift work, especially night-time work, and the development of breast cancer among nurses. Materials and Methods: A systematic review of the literature was carried out through the consultation of the following databases: Cochrane Plus Library, PubMed, CINAHL (Cumulative Index to Nursing and Allied Health Literature), Web of Science, ScienceDirect, Scopus, and Dialnet. Records were selected between 2010 and 2020, in Spanish and English, which covered the association between breast cancer diagnosed among nursing professionals and rotating night shifts. Results: A total of 12 studies were identified after critical reading. Most of the studies found an association between breast cancer and consecutive rotating night shifts prolonged over time. Among the associated factors, the alteration of the circadian rhythm influenced the expression of peripheral clock genes, which was the same as reproductive hormones. The risk of breast cancer in nurses increased during early adulthood and after 5 or more years with 6 or more consecutive nights. Conclusions: The different studies of this review show significant associations between breast cancer and prolonged rotating night shifts. Similarly, there is a relationship between the alterations in certain circadian rhythm markers (such as melatonin), epigenetic markers (such as telomeres), and breast cancer that would require more studies in order to corroborate these findings.

Merger processes between hospitals have high benefit potential for patients, staff and managers. This integration of health centres can improve the quality and safety in patient care. Additionally, cooperative processes enhance the sustainability of the health system, by increasing team spirit, giving innovative ideas and improving staff satisfaction. In this article, the critical factors for successful hospital mergers and acquisitions in the Public Health System were considered to develop a brief guide to help with the organisation of a merger process. Five sections were designed: Strategic administration and objectives, Staff management, New hospital complex structure, Processes and Results. This guide facilitates the communication between a variety of stakeholders, thus improving the engagement between all members of the new healthcare system. This could be particularly important for countries with large regional variance in the organisation of health care and resources.

Since the beginning of the COVID-19 pandemic, a major impact on the mental health of the population has been observed, with women being one of the most affected groups. From the lockdown to “de-escalation” phases, sex differences have been recognised as significant determinants of mental health. Thus, equally ensuring physical and mental protection at work remains one of the challenges faced by industrial companies, especially in the construction sector, where the percentage of employed women has increased in recent years. This study aims to examine the impact of sex differences on psychological distress and work engagement in the productive construction sector, as well as related variables. For this, a cross-sectional descriptive study was performed. Descriptive statistical analyses were completed, and non-parametric Mann-Whitney U and Chi-squared tests were used to identify differences between men and women. This was followed by logistic regression analysis by sex. Psychological distress is more prevalent among women, even after controlling for most variables. Both sexes receive equal preventive measures and training from the companies, yet women still experience higher levels of psychological distress. At the beginning of the pandemic, women reported higher levels of anxiety and fear of COVID-19 and of perceived danger associated with the pandemic than men. However, these differences were not present by 2023. For men, work engagement appeared to be a determining factor for a stable mental health, while for women, health and physical status seemed to be more influential. In both sexes, psychological distress was found to be conditioned by mental and emotional well-being. In a sector where women are increasingly present, the differences observed in terms of how physical and mental health are affected across the two sexes justify the need to promote data analysis that acknowledges this reality.

The COVID-19 pandemic posed a major challenge for construction companies, which were confronted with the need to prevent the enormous negative socio-psychological impact of the pandemic on their employees. The aim of this study was to evaluate the level of psychological distress among construction workers in an advanced phase of the COVID-19 pandemic in Andalusia, southern Spain. For this, a cross-sectional descriptive study was conducted using online questionnaires with data on sociodemographic variables and employment situation, COVID-19 pandemic-related data, and Goldberg’s General Health Questionnaire (GHQ-12). A total of 860 questionnaires from all provinces of Andalusia, Spain, were collected between March and May 2022. Descriptive statistical analyses and non-parametric Mann–Whitney U and Chi-squared tests were performed, followed by logistic regression analysis. The incidence of psychological distress was higher among women, individuals under 43 years of age, those with a family income below EUR 1200, participants whose working conditions had been affected by the pandemic, those who had not received adequate means or specific training to protect themselves from infection, those who had experienced symptoms, those who had suffered side effects after vaccination, and those who had been hospitalised. The logistic regression analysis predicted the occurrence of psychological distress in this study by the effect of the pandemic on mental/emotional well-being, the working conditions affected during the pandemic, health-related variables, and the age of the worker. The correctly classified percentage was 75.1%. Assessing psychological distress in construction sectors may allow for the identification of vulnerable groups or even help to reduce the number of errors in daily practice and potential risks of occupational injury or illness.

Con la aparición de la COVID-19, la sociedad ha tenido la necesidad de buscar información sobre la pandemia y las fuentes de información usadas para ello han sido muy diversas, con un mayor predominio de las redes sociales, los medios tradicionales y la consulta a las personas allegadas. Además, se ha observado un exceso de información en los medios de comunicación que dificultaba el acceso y el entendimiento, así como una constante preocupación y ansiedad por la salud, lo cual provocaba una necesidad de búsqueda de información excesiva o repetida sobre la salud y la enfermedad. Esta información no siempre estaba avalada por la comunidad científica y durante la pandemia se han sucedido la difusión de información errónea, de las llamadas fake news y de las teorías de conspiración sobre la COVID-19 difundidas, principalmente, a través de las redes sociales. En este sentido, tanto los conocimientos como las creencias aprehendidas han podido impactar en la salud mental de la población.

This study aims to evaluate evacuation performance in a high-acuity intensive care unit (ICU) by integrating building information modeling (BIM) and computational simulation and examine how different parametrizations affect the fidelity of predicted evacuation dynamics when compared with data from a real evacuation drill. A detailed BIM model of a tertiary hospital ICU was developed and imported into Pathfinder to simulate 3 protocol-based evacuation scenarios and 1 scenario calibrated with preparation times obtained from a 2024 evacuation drill. Simulations assessed occupant flow, bottlenecks, movement trajectories, and total evacuation times. Architectural constraints, behavioral rules, and patient dependency profiles were incorporated to reflect real operational conditions, including explicit geometric incompatibilities between door widths and ICU bed dimensions. Evacuation times produced with generic parameters showed a gap of up to 7 minutes 40 seconds less than the real drill duration, whereas the empirically calibrated simulation narrowed this difference to 2 minutes 30 seconds. Across all scenarios, bottlenecks consistently emerged at the main critical patient unit exit, primarily driven by architectural constraints such as insufficient door widths relative to bed size, which hindered bed maneuverability and intensified staff circulation conflicts. Flow rates peaked between 0.40 and 0.55 persons/s, with higher occupancy producing more sustained congestion. Preparatory actions for clinically complex patients significantly shaped overall evacuation performance. The integration of BIM and empirically informed simulation enhances the accuracy and operational relevance of evacuation analyses in complex clinical environments. Findings highlight the need for calibration based on real behavioral data and demonstrate how specific architectural mismatches, particularly between door geometry and bed dimensions, act as critical drivers of evacuation bottlenecks. This approach supports more robust risk assessment and emergency planning within critical socio-technical infrastructures.
