Posibilidades y limitaciones del programa Intercambio de Saberes : Análisis de su implementación en tres escuelas técnicas agropecuarias de la provincia de Río Negro
Full text linkLa pandemia afectó significativamente la Educación Técnico-Profesional en Argentina, especialmente en las escuelas técnicas, que enfrentaron grandes dificultades para continuar con las prácticas profesionalizantes, como campo fundamental para la formación técnica (Garino y Fernández, 2023). En este contexto, surgió el programa "Intercambio de Saberes", implementado en la provincia de Río Negro durante 2022 y 2023, bajo la coordinación de la Dirección de Educación Técnica y Formación Profesional, en el marco del Proyecto de Mejora Jurisdiccional. El programa buscó fomentar el aprendizaje de saberes técnicos a través de intercambios entre estudiantes e instituciones, destacando el valor de las experiencias colaborativas. Esta investigación, de enfoque cualitativo, incluyó el análisis de fuentes documentales para reconstruir el origen de la iniciativa y la implementación de diferentes intercambios en ciertas especialidades técnicas. También se realizaron entrevistas al referente provincial y docentes de escuelas que han participado de la experiencia. Los resultados muestran que el programa permitió, a los estudiantes, conocer espacios formativos asociados con la práctica y sus vínculos con el sector socio-productivo, poniendo en valor sus competencias profesionales y otras transversales. No obstante, la implementación enfrentó desafíos como la falta de planificación adecuada y de recursos, además de una estrategia de evaluación para analizar su impacto en el aprendizaje. Aunque el programa presenta rasgos innovadores, planteamos ciertos interrogantes sobre sus efectos en los estudiantes próximos a egresar y su vinculación con el mundo del trabajo.Peer reviewe
An Introduction to Quantum Mechanics Through Neuroscience and CERN Data
No full textPublisher Copyright: © 2025 by the authors.(1) Background: One of the greatest challenges students face when studying quantum mechanics is the lack of daily experience and intuition about its concepts. This article introduces a holistic activity designed to present some foundational ideas of quantum mechanics in a new pedagogical approach to enhance students’ motivation. Using real open data from CERN, the activity connects classical concepts of dynamics and electromagnetism to their quantum counterparts, emphasizing both their similarities and differences. Teaching physics must consider the way the brain learns. That is why the activity is based on observed neuroscientific principles of physics learning. The approach maintains the rigor and precision required for these abstract concepts. (2) Methods: To evaluate the activity’s impact by gender, intrinsic motivation was assessed using a Likert-type scale with 81 undergraduate students from fields including artificial intelligence systems engineering, computer engineering, mathematical engineering, and architecture. (3) Results: a Mann–Whitney U test analysis indicates the activity significantly enhances students’ intrinsic motivation to study quantum mechanics, with improvements observed in both male and female students. (4) Conclusions: This result highlights the potential of the activity to promote greater interest in physics, both in men and women, since no significant differences have been observed between both samples.Peer reviewe
Mobile applications for non-communicable disease Management : A systematic review of development methods and effectiveness
Full text linkPublisher Copyright: © 2025 The AuthorsAim: To evaluate the most effective development methods for mobile applications that support self-management of non-communicable diseases and to determine the features that enhance their effectiveness and user adoption. Methods: The design was a systematic review of research papers published in the period 2019–2024. The review included randomized and quasi-experimental clinical trials. The search was performed in six databases (PubMed, Scopus, Scielo, CINAHL, Web of Science, and Clinical Trials). Bias and methodological quality were assessed using the RoB2 and MINORS tools. Results: The review included six studies involving 2421 patients across four countries. The applications demonstrated improvements in treatment adherence, self-efficacy, and control of clinical variables such as glycemia and blood pressure. The most effective applications incorporated therapeutic education, monitoring, and reminders. However, limitations were noted, including insufficient user involvement in early development stages, which could affect relevance and usability. The heterogeneity of study designs and populations, coupled with the lack of large-scale clinical trials, limits the generalizability of the findings. Additionally, variability in technological platforms and the absence of standardized evaluation metrics complicate outcome comparisons. Conclusion: Mobile applications for chronic disease self-management are most effective when developed with a user-centered approach and continuous validation. Despite these findings, further research is necessary to generalize the results and optimize the integration of these applications into healthcare systems.

Characterization of a nosocomial outbreak caused by VIM-1 Klebsiella michiganensis using Fourier transform infrared (FT-IR) spectroscopy
No full textPublisher Copyright: © 2025 The Healthcare Infection SocietyBackground: Fourier transform infrared (FT-IR) spectroscopy has emerged as a rapid and reliable method for bacterial typing. In this study, we evaluated FT-IR spectroscopy for characterizing a nosocomial outbreak caused by VIM-1-producing Klebsiella michiganensis (K. oxytoca complex). Methods: All K. oxytoca complex isolates collected during the outbreak period (N = 27) and control isolates (N = 8) were obtained from Hospital Universitario Gregorio Marañón, Spain. Among the 27 isolates, 22 were obtained from paediatric patients, four from adults and one was an environmental isolate. FT-IR spectroscopy was employed for bacterial typing, while whole-genome sequencing (WGS) was used as the reference typing method for comparison. Findings: Analysis of the FT-IR spectra revealed distinct clusters, one of which corresponded to 19 outbreak isolates (18 from paediatric patients and the environmental isolate), suggesting a common origin. Other minor clusters did not exhibit any epidemiological relationship among the isolates. Subsequent WGS analysis identified K. michiganensis as the causative agent of the outbreak. FT-IR showed a high concordance with WGS in outbreak classification, supporting its reliability in this setting (adjusted Rand index = 0.882; adjusted Wallace coefficient = 0.937). Moreover, FT-IR spectra visualization highlighted discriminative features between outbreak and non-outbreak isolates, facilitating rapid screening when an outbreak is suspected. Conclusions: FT-IR spectroscopy represents a rapid and cost-effective method that enables timely intervention and effective management of nosocomial outbreaks. Its integration with WGS enhances the accuracy of outbreak investigations, demonstrating its utility in clinical microbiology and infection control practices.Peer reviewe
Picoplankton nitrogen guilds in the tropical and subtropical oceans : From the surface to the deep
No full textPublisher Copyright: © 2025 Rivas-Santisteban et al. This is an open access article distributed under the terms of the Creative Commons Attribution License, which permits unrestricted use, distribution, and reproduction in any medium, provided the original author and source are credited.Ecological guilds quantify the incidence and extent of resource transformation functions, irrespective of the species involved. Therefore, tackling the microbial nitrogen guilds is key to our understanding of the oceanic nitrogen cycle, but quantitative estimates of guild contribution across varying depths and under specific environmental conditions have yet to be accomplished. In this study, we examine the main picoplankton guilds participating in nitrogen cycling within the low and mid-latitude ocean ecosystems, from the surface down to 4000 m, using data obtained from 75 samples belonging to 11 stations in the Malaspina dataset. In particular, we used a quantitative approach to investigate the stability of nitrogen acquisition and nitrogen-redox guilds separately. Our results showed that nitrogen acquisition guilds are more stable and redundant than nitrogen-redox guilds across depths and site specific conditions. For example, differential conditions such as nitrogen depletion and oxygen availability affected the two groups of guilds in different ways. These findings have implications for the understanding of global nitrogen fluxes and the biosphere’s functional diversification.Peer reviewe

Published by BMJ Group.Objective A synthesis and appraisal of the recommendations for biomarkers in practice guidelines concerning sepsis is required to consolidate evidence-based practice. We generated an evidence gap map (EGM) on the use of biomarkers for managing adults with sepsis. Design Scoping review. Data sources MEDLINE, Guidelines International Network, Pan American Health Organization, Trip Database and UpToDate were searched from 2016 to March 2025. Eligibility criteria Guidance documents (GD) that searched at least one literature source and provided clinical recommendations for the use of biomarkers for the management (diagnosis and prognosis, including treatment response) of adults with sepsis. Data extraction and synthesis Two reviewers independently applied the eligibility criteria and extracted data. We used the AGREE-II (Appraisal of Guidelines for Research and Evaluation) tool to assess the GD quality. GDs that scored ≥50% on the AGREE-II 'Rigour of development' domain were considered robust. We also applied the GRADE (Grading of Recommendations Assessment, Development and Evaluation) system to evaluate if the recommendations were strong or conditional. Results We found 10 GDs, with only half (4/8) having a robust methodology. There were 31 recommendations concerning biomarkers. Among these, 24 (77.4%) recommendations were about single biomarkers, with lactate (23; 74.2%) and procalcitonin (8; 25.8%) most frequently recommended. Biomarker testing focused on prognosis in 28 (90.3%) recommendations. Overall, 16 (51.6%) recommendations were graded strong and 13 (42.0%) were conditional, which we displayed in an EGM. Conclusions The methodology of GDs concerning adult sepsis was poor. Our review calls for more prudent use of biomarkers in specific prognostic scenarios and in combination with standard clinical assessments. Enhancing the methodological quality of future GDs is essential to generate more valid and robust recommendations for optimising patient care.Peer reviewe
Psychological Care in Spanish Nurses at the Frontline of the COVID-19 Pandemic : A Prospective Study on Symptoms, Burnout and Psychological Variables
No full textPublisher Copyright: © 2025 by the authors.(1) Background: Previous studies have highlighted the emotional symptoms experienced throughout the COVID-19 pandemic by nurses and their consequences. It would be of interest to analyze the extent to which healthcare workers (HCWs), in the context of the psychological health crisis, have sought (and received) psychological care. Likewise, it would be highly relevant to analyze the profile of these professionals, both in terms of the sociodemographic and occupational characteristics as well as the emotional symptoms they presented, and the percentage of nurses who requested psychological help during the COVID-19 pandemic, their sociodemographic and occupational characteristics as well as their levels of associated symptoms. Additionally, one could study the associated psychological personality variables, including both risk factors and protective variables, as this is of special interest for the design of appropriate interventions. (2) Methods: An observational, descriptive, prospective longitudinal study with three data collection periods was carried out. At the first time point, anxiety, insomnia, self-efficacy, resilience and social support were assessed. Anxiety, insomnia, fear of COVID-19, cognitive fusion and burnout syndrome were assessed at the second time point. Finally, at the third time point, we assessed anxiety, insomnia and burnout syndrome. During the second and third time points, the nurses’ requests for psychological help were assessed. (3) Results: Overall, 33.1% of the final sample requested psychological support, and 20.5% of them had sought psychological support by the first time point, of which 7.3% continued to in the final time measure. The request for psychological help was significantly related to higher means for anxiety (p = 0.003), insomnia (p = 0.001) and burnout (p < 0.05), as well as high levels of cognitive fusion (p = 0.001) and low levels of resilience (p = 0.009). Requests for psychological help were not significantly related to social support (p = 0.222) or fear of COVID-19 (p = 0.625). (4) Conclusions: The data suggest the need to promote measures for the implementation of psychological help among nurses aimed not only at reducing the consequences of the psycho-emotional affectation derived from a stressful work situation but also strengthening health-promoting traits such as self-efficacy or resilience.Peer reviewe
Understanding Human Disability Through the Servant of Yahweh
Full text linkPublisher Copyright: © 2025 The Author(s). Published with license by Taylor & Francis Group, LLC.The Fourth Song of the “Servant of Yahweh” from the Book of the prophet Isaiah (Is 52:13–53:12) shed light that enlightens those who suffer from disability. The Servant of Yahweh serves as a prefiguration of those who endure innocent suffering, particularly those with disabilities. Through their suffering, God communicates a message, revealing them as bearers of a sign of God’s presence and even of salvation for those who know how to welcome them. In this sense, inclusion becomes an opportunity to receive a divine gift. The poem of the Servant reveals a vulnerable God and offers light on the question of human disability through three points: 1) the silence of God, 2) disability and divine vulnerability, and 3) disability as an opportunity for victory over evil. This article recovers a theological reflection that is current and necessary to understand the mystery of the suffering particularly the suffering of the innocent, specifically, those with disabilities.Peer reviewe
