PHIL-GAMES II: Incorporación de la herramienta de gamificación Kahoot como instrumento para la motivación y evaluación del aprendizaje en asignaturas del Grado en Filosofía (2º año)

Innovación EducativaEn el curso 2021-2022 el proyecto PHIL-GAMES tuvo como objetivo principal servir como experiencia piloto para la incorporación de Kahoot en el Grado en Filosofía, para: (a) aumentar la interacción entre alumnos y profesores en el aula; (b) mejorar el interés, motivación y compromiso de los alumnos; (c) seguir mejor el proceso de aprendizaje de los alumnos y las dificultades encontradas; (d) incrementar la asistencia a clase y la participación en el aula; y (e) mejorar los resultados y el rendimiento académico del alumnado. En el presente curso 2022-23 la herramienta Kahoot se ha incorporado en otras tres asignaturas obligatorias del Grado en Filosofía (Filosofía del Lenguaje I, Filosofía del Lenguaje II y Lógica II) y se ha seguido aplicando en la asignatura Filosofía de la Ciencia II. Con ello, doblamos el número de asignaturas gamificadas, creciendo considerablemente la base de alumnos beneficiados con esta actividad. Para su ejecución, se han seguido empleando los protocolos y herramientas desarrollados en la primera edición del proyecto. De modo análogo a lo hecho en el curso anterior, se han elaborado los cuestionarios de preguntas Kahoot para las nuevas asignaturas incorporadas. Además, se han reforzado los procesos de realimentación en las actividades gamificadas. Para ello, hemos dado un mayor peso y atención a las partes de debate y discusión posteriores a la resolución de los cuestionarios. También hemos revisado, actualizado y ampliado los instrumentos empleados para la recolección de la opinión y grado de satisfacción del alumnado (en base a la experiencia tenida en el curso 2021-22 y al feedback recibido de los alumnos).Departamento de Filosofía (Filosofía, Lógica y Filosofía de la Ciencia, Teoría e Historia de la Educación, Filosofía Moral, Estética y Teoría de las Artes)Trabajo financiado con un proyecto de innovación docente: Vicerrectorado de Innovación Docente y Transformación Digital (Universidad de Valladolid

Cultura y sociedad en movimiento

La presente compilación de textos, que aborda temáticas diversas sobre cultura y sociedad, es corolario de un esfuerzo compartido de profesores investigadores y alumnos de licenciatura y posgrado con el fin de dar a conocer resultados de las investigaciones que se están realizando en el organismo académico, incluyendo, por supuesto, otros trabajos llevados a cabo por colegas de instituciones y disciplinas afines; de esta manera se fortalecen los cuerpos académicos y se promueven las líneas de generación y aplicación del conocimiento de éstos, evidenciando algunos campos de conocimiento de la antropología.Como es manifiesto, la obra en su conjunto aborda distintos temas desde diversas perspectivas epistemológicas y teórico-conceptuales. Constituye un trabajo plural que articula la perspectiva antropológica, con otras lentes disciplinares. Cuerpo, agricultura, desigualdad y bienestar se entrelazan como ejes en principio divergentes, que hallan en lo sociocultural un elemento común de análisis. Así, los textos aquí englobados tienen la expectativa de aportar en la discusión contemporánea de viejos y nuevos derroteros de interés antropológico, y social en general

Characterising the KMP-11 and HSP-70 recombinant antigens' humoral immune response profile in chagasic patients

11 pages, 6 figures.-- The pre-publication history for this paper can be accessed here: http://www.biomedcentral.com/1471-2334/9/186/pre pubBackground: Antigen specificity and IgG subclass could be significant in the natural history of Chagas' disease. The relationship between the different stages of human Chagas' disease and the profiles of total IgG and its subclasses were thus analysed here; they were directed against a crude T. cruzi extract and three recombinant antigens: the T. cruzi kinetoplastid membrane protein-11 (rKMP-11), an internal fragment of the T. cruzi HSP-70 protein192-433, and the entire Trypanosoma rangeli HSP-70 protein. Methods: Seventeen Brazilian acute chagasic patients, 50 Colombian chronic chagasic patients (21 indeterminate and 29 cardiopathic patients) and 30 healthy individuals were included. Total IgG and its subtypes directed against the above-mentioned recombinant antigens were determined by ELISA tests. Results: The T. cruzi KMP-11 and T. rangeli HSP-70 recombinant proteins were able to distinguish both acute from chronic chagasic patients and infected people from healthy individuals. Specific antibodies to T. cruzi crude antigen in acute patients came from IgG3 and IgG4 subclasses whereas IgG1 and IgG3 were the prevalent isotypes in indeterminate and chronic chagasic patients. By contrast, the specific prominent antibodies in all disease stages against T. cruzi KMP-11 and T. rangeli HSP-70 recombinant antigens were the IgG1 subclass.This work was supported by Colciencias Research project No. 1203-333- 18692.

Treatment with tocilizumab or corticosteroids for COVID-19 patients with hyperinflammatory state: a multicentre cohort study (SAM-COVID-19)

Objectives: The objective of this study was to estimate the association between tocilizumab or corticosteroids and the risk of intubation or death in patients with coronavirus disease 19 (COVID-19) with a hyperinflammatory state according to clinical and laboratory parameters. Methods: A cohort study was performed in 60 Spanish hospitals including 778 patients with COVID-19 and clinical and laboratory data indicative of a hyperinflammatory state. Treatment was mainly with tocilizumab, an intermediate-high dose of corticosteroids (IHDC), a pulse dose of corticosteroids (PDC), combination therapy, or no treatment. Primary outcome was intubation or death; follow-up was 21 days. Propensity score-adjusted estimations using Cox regression (logistic regression if needed) were calculated. Propensity scores were used as confounders, matching variables and for the inverse probability of treatment weights (IPTWs). Results: In all, 88, 117, 78 and 151 patients treated with tocilizumab, IHDC, PDC, and combination therapy, respectively, were compared with 344 untreated patients. The primary endpoint occurred in 10 (11.4%), 27 (23.1%), 12 (15.4%), 40 (25.6%) and 69 (21.1%), respectively. The IPTW-based hazard ratios (odds ratio for combination therapy) for the primary endpoint were 0.32 (95%CI 0.22-0.47; p < 0.001) for tocilizumab, 0.82 (0.71-1.30; p 0.82) for IHDC, 0.61 (0.43-0.86; p 0.006) for PDC, and 1.17 (0.86-1.58; p 0.30) for combination therapy. Other applications of the propensity score provided similar results, but were not significant for PDC. Tocilizumab was also associated with lower hazard of death alone in IPTW analysis (0.07; 0.02-0.17; p < 0.001). Conclusions: Tocilizumab might be useful in COVID-19 patients with a hyperinflammatory state and should be prioritized for randomized trials in this situatio

Clonal chromosomal mosaicism and loss of chromosome Y in elderly men increase vulnerability for SARS-CoV-2

The pandemic caused by severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2, COVID-19) had an estimated overall case fatality ratio of 1.38% (pre-vaccination), being 53% higher in males and increasing exponentially with age. Among 9578 individuals diagnosed with COVID-19 in the SCOURGE study, we found 133 cases (1.42%) with detectable clonal mosaicism for chromosome alterations (mCA) and 226 males (5.08%) with acquired loss of chromosome Y (LOY). Individuals with clonal mosaic events (mCA and/or LOY) showed a 54% increase in the risk of COVID-19 lethality. LOY is associated with transcriptomic biomarkers of immune dysfunction, pro-coagulation activity and cardiovascular risk. Interferon-induced genes involved in the initial immune response to SARS-CoV-2 are also down-regulated in LOY. Thus, mCA and LOY underlie at least part of the sex-biased severity and mortality of COVID-19 in aging patients. Given its potential therapeutic and prognostic relevance, evaluation of clonal mosaicism should be implemented as biomarker of COVID-19 severity in elderly people. Among 9578 individuals diagnosed with COVID-19 in the SCOURGE study, individuals with clonal mosaic events (clonal mosaicism for chromosome alterations and/or loss of chromosome Y) showed an increased risk of COVID-19 lethality

Scribble basal polarity acquisition in RPE cells and its mislocalization in a pathological AMD-like model

Apicobasal polarity is a hallmark of retinal pigment epithelium cells and is required to perform their functions; however, the precise roles of the different proteins that execute polarity are still poorly understood. Here, we have studied the expression and location of Scribble, the core member of the polarity basal protein complex in epithelial-derived cells, in human and mouse RPE cells in both control and pathological conditions. We found that Scribble specifically localizes at the basolateral membrane of mouse and human RPE cells. In addition, we observed an increase in the expression of Scribble during human RPE development in culture, while it acquires a well-defined basolateral pattern as this process is completed. Finally, the expression and location of Scribble were analyzed in human RPE cells in experimental conditions that mimic the toxic environment suffered by these cells during AMD development and found an increase in Scribble expression in cells that develop a pathological phenotype, suggesting that the protein could be altered in cells under stress conditions, as occurs in AMD. Together, our results demonstrate, for the first time, that Scribble is expressed in both human and mouse RPE and is localized at the basolateral membrane in mature cells. Furthermore, Scribble shows impaired expression and location in RPE cells in pathological conditions, suggesting a possible role for this protein in the development of pathologies, such as AMD.This study has been funded by Instituto de Salud Carlos III (ISCIII) through the projects PI15/01240 and PI18/01536 co-funded by the European Union (to CL) and by grants from Consejería de Sanidad de la Junta de Castilla y León (GRS2334/A/21 and GRS2167/1/2020).
