Second victim syndrome among nursing professionals as a result of COVID-19: qualitative research
No full textIntroduction
The infection caused by the COVID-19 virus, with its high capacity for spread and transmission, reached the level of an international pandemic, affecting many people and resulting in a large number of deaths.
Aim
To analyse the experiences of nursing professionals caring for patients with COVID-19 during the early stages of the pandemic and the skills or coping strategies that they employed.
Methods
A qualitative study was carried out with an interpretative phenological design. Semistructured interviews were conducted with 20 nursing professionals working in emergency and critical care units, which were adapted to care for patients with symptoms of the disease, in public hospitals in Madrid, Spain. The data were analysed following, the Interpretive Phenomenological Analysis (IPA) of Smith et al.
Findings
Five themes were identified: “emotional brain training (EBT) to cope with great emotional stress”, “material and sequential difficulties”; “an experience similar to a war that can cause burnout”; “Second Victim Syndrome (SVS), the emotional impact of witnessing trauma”; and “Surviving COVID-19 with overloads of energy and positivity”.
Conclusion
Nursing professionals who cared for patients with Covid-19 during the first wave of the pandemic lived an experience in which they experienced a brain training of feelings, including sadness, impotence, fear, anger, pain and much worry. They also experienced a great feeling of suffering and guilt as in Second Victim Syndrome, in a situation similar to a war, due to the number of deaths caused by the virus, with all this resulting in a great overload of work. It is essential that these situations do not affect the mental health of these professionals in the dimensions that they did, and it is necessary to regain enthusiasm and motivation to provide comprehensive care for patients with COVID-19. Nursing professionals are not alone and need to be taken care of to respond to the chaos that can cause a pandemic, without ignoring the risks that it entails. They require specific training, which is necessary to provide them with proper security, and it is necessary to develop health and welfare policies, which will not be possible without first understanding their experiences

Complexity of the Relationship between Environmental Factors, Interspecific Competition, and Intrinsic Traits of the Species in Explaining the Invasive Success of Gobio lozanoi Doadrio & Madeira, 2004
No full textThe increase of non-native species in rivers is of great concern. To assess the potential impact of a species it is necessary to consider the ecological state of the receiving ecosystem and the biology of the potentially invasive species. In this work we characterize two populations of Gobio lozanoi Doadrio & Madeira, 2004 (bio-metric and demographic parameter) and the invasibility (as a function of habitat quality, competing species, food supply, etc.) of the two rivers that they inhabit. In addition, biomarkers of energy reserve level are analyzed to investigate their role in the invasiveness of the species. The results show differences in energy reserve levels and invasiveness between the two fish populations, and differences in the potential invasibility of the two tributaries. In the river with lower resistance to invasion, the G. lozanoi population is well-structured, and specimens have higher lipid values. On the contrary, in the river with better ecological status (and therefore greater resistance to invasion) we found lower lipid values, higher protein values and low juvenile survival rate. The lipid level is revealed as a good indicator of invasiveness in populations of alien species, under favorable conditions for invasion
The Role of Phenotypic Plasticity and Within-Environment Trait Variability in the Assembly of the Nectar Microbiome and Plant-Microbe-Animal Interactions
No full textThe study of the rules that govern the relationship between phenotypic plasticity, genetic structure, and ecological success has traditionally focused on animals, plants, and a few model microbial species, whereas non-model microorganisms have received much less attention in this regard. The floral nectar of angiosperms is an ephemeral, island-like habitat for different highly adapted yeasts and bacteria. The growth of microorganisms in floral nectar depends on their ability to efficiently use the available nutrients and tolerate challenging physicochemical conditions, including high osmotic pressures, unbalanced carbon-to-nitrogen ratios, and the presence of diverse defensive compounds of plant origin. The production of alternative phenotypic states in response to environmental cues (i.e., phenotypic plasticity) or independently from these (within-environment trait variability) might be particularly relevant in floral nectar, in which rapid growth is needed for population persistence and to improve the chance of animal-mediated dispersal. In this article, we use the nectar microbiome as an example to encourage further research on the causes and ecological consequences of phenotypic plasticity and within-environment trait variability of microbes. We review previous work on the mechanisms and potential ecological significance of the phenotypic plasticity and within-environment trait variability displayed by nectar yeasts and bacteria. Additionally, we provide an overview of some topics that require further attention, including potential trade-offs between different traits that are relevant for adaptation to dynamic nectar environments and the direct and indirect effects of phenotypic variability on the fitness of plants, flower-visiting animals, and other nectar microbes. We conclude that further research on the causes and ecological consequences of phenotypic plasticity and within-environment trait variability of microbes is essential to get a better understanding of community assembly and the establishment of ecological interactions in floral nectar and other similar highly dynamic and strongly selective microbial habitats
VIRTUAL PRODUCTION EN THE MANDALORIAN:TECNOLOGÍA, HIPERTEXTUALIDAD E ISOMORFISMO SEMIÓTICO
No full textSince its inception, audiovisual media has not always been able to faithfully translate the dramatic space and narrative from the written text to the moving image. Advances in technologies offer new tools to generate visually plausible narratives. The medium is now a mixed reality, consisting of the real world and a virtual metaverse.The present article analyses the role of emerging technologies in creating virtual elements within film narratives and their influence on the process of semiosis, both in the realm of fiction and potentially in the real world through ‘fake news’. To achieve these research objectives, a connotative-denotative and syntagmatic-paradigmatic analysis was made of a film fragment to observe the influence of digital technology on the process of audiovisual semiosis. The study found that these technologies offer new tools for the production of meaning
Engineered mesoporous silica nanosystems with organotin(iv) complexes containing 1-(quinolin-8-yliminomethyl)naphthalen-2-ol ligand for cancer cell targeting
No full textThe development of targeted nanotherapeutics has emerged as a promising approach to improve the efficacy and safety of anticancer treatments. This manuscript presents the synthesis, detailed characterization, and biological evaluation of novel mesoporous silica nanoparticles (sMSNs) functionalized with organotin(IV) complexes containing 1-(quinolin-8-yliminomethyl)naphthalen-2-ol ligand, which have also been selectively targeted using biotin (BT) and folic acid (FA). The systems have been comprehensively characterized using microscopy, nitrogen adsorption–desorption isotherms, and several spectroscopic methods confirming the successful conjugation of organotin(IV) complexes and targeting ligands, as well as the preservation of the structural integrity of the nanoparticles. The cytotoxic potential of the functionalized sMSNs was assessed in vitro using cancer cell lines (HeLa and MCF-7) and non-cancerous cell lines (Hek 293T and RPE-1) to evaluate their selectivity and biocompatibility. The results demonstrated that the tin-functionalized nanoparticles exhibited a significant antiproliferative activity. Notably, the incorporation of BIO and FA as targeting ligands enhanced selectivity toward cancer cells, minimizing toxicity in healthy cells. Our compounds were found to have a higher cytotoxic activity than cisplatin. These findings highlight the potential of tin-functionalized mesoporous silica nanoparticles as a robust platform for targeted cancer therapy, offering enhanced efficacy and reduced off-target effects compared to conventional platinum-based treatments.PID2022-136417NB-I00 financed by Ministerio de Ciencia, Innovación y Universidades/Agencia Estatal de Investigación of Spain MCIU/AEI/10.13039/501100011033/ and “ERDF A way of making Europe”, and from the Research Thematic Network RED2022-134091-T financed by Ministerio de Ciencia, Innovación y Universidades/Agencia Estatal de Investigación of Spain MCIU/AEI/10.13039/501100011033.

La pérdida de trascendencia y el ascenso del Leviatán
No full textTrabajo Fin de Máster leído en la Universidad Rey Juan Carlos en el año 2025, Director: Óscar Rodríguez CarreiroEste TFM analiza cómo la pérdida de trascendencia, basada esta en el cristianismo, ha contribuido a la decadencia y la expansión del Estado. Las ideas tienen consecuencias, y la decadencia se puede trazar desde el nominalismo hasta el Estado-nación, pasando por el protestantismo, la ilustración y la moderna revolución sexual. Se usarán los métodos que presenta la Escuela Austriaca de Economía para analizar cómo los tentáculos del Leviatán: democracia, inflación y asistencialismo, han aumentado esta tendencia nihilista, que destruye los pilares básicos del orden social: fe, familia y propiedad
La reparación (incompleta) de las agresiones sexuales a menores en actividades deportivas en España. A raíz de la condena Larry Nassar y de la aprobación de la Ley de Protección a la Infancia
No full textEn diciembre de 2021, conocimos la sentencia condenatoria al ex médico de la Selección de Gimnasia de Estados Unidos Larry Nassar. Este hombre ha sido condenado por abusos sexuales a múltiples gimnastas menores de edad; más allá de la pena, me resulta interesante señalar la cantidad de 380 millones a la que han sido condenadas USA Gymnastics y el Comité Olímpico estadounidense para reparar el daño causado a las víctimas, nos encontramos ante una indemnización punitiva, propia de los sistemas anglosajones. El presente trabajo sirve para exponer algunos de los casos más recientes de agresiones sexuales a menores, de dieciséis años, en actividades deportivas en España y la reparación del daño en estos casos. El autor parte de la premisa de la diferencia entre las indemnizaciones en los sistemas que admiten los daños punitivos y los que no. En España, la función principal de la responsabilidad civil es la reparación del daño causado, devolviendo a la víctima a la situación anterior al perjuicio causado; en cambio, en el Caso de Larry Nassar, la indemnización establecida tiene un componente punitivo, esta circunstancia provoca la elevación de la suma indemnizatoria. Además, el presente trabajo pretende señalar los principales problemas que nos encontramos en el proceso de reparación del daño de los menores víctimas de abusos sexuales; por un lado, el problema de la prescripción del delito y de la acción civil; y, de otro lado, la valoración de los daños morales
