Adaptación de las asignaturas básicas de primer curso de la ETSI Navales de la UPM: Actividades 2008-2009

En el marco de la reforma de las titulaciones con motivo del Espacio Europeo de Educación un grupo de profesores hemos coordinado, durante el curso 2008-2009, todas las asignaturas básicas de primer curso y una más de segundo curso en la Escuela Técnica Superior de Ingenieros Navales. Las actividades realizadas son: a) Coordinación de todas las asignaturas básicas de primer curso, con reuniones periódicas de coordinación horizontal y el establecimiento de una página web de moodle para profesores como espacio para el trabajo cooperativo. Particularmente importante es el establecimiento de un calendario conjunto de pruebas de evaluación continua. b) Redacción de guías de aprendizaje, con un formato común para todas las asignaturas, incluyendo los objetivos formativos, los contenidos, las actividades formativas, los enlaces y la bibliografía. c) Establecimiento de una plataforma de teleeducación común para todas las asignaturas, uno de los objetivos fundamentales del proyecto, ya que coexistían dos plataformas distintas. Igualmente importante ha sido reforzar los contenidos y las actividades que se podían realizar en la plataforma. d) Seguimiento del tiempo dedicado por los alumnos, hemos ido siguiendo el tiempo dedicado por los alumnos a las distintas asignaturas, para detectar si el tiempo que se dedica está en los márgenes establecidos en los créditos ECTS. Igualmente, hemos hecho dos encuestas a la mitad de cada semestre, para recoger las opiniones de los alumnos sobre las asignaturas y sobre los aspectos relevantes del proyecto. e) Organización de actividades de nivelación, para los alumnos de nuevo ingreso, con la organización de cursos cero y la participación y coordinación en la Plataforma de Punto de inicio de la UPM. f) Organización de actividades formativas, para poder llevar a cabo estas tareas, hemos organizado, en colaboración con el Centro y el Gabinete de Tele-Educación (GATE) actividades formativas relacionadas con la plataforma moodle, métodos de evaluación y de formación en competencias.En la presentación haremos una descripción de las actividades realizadas, así como una primera evaluación de las mismas. Por último, describiremos las tareas a desarrollar en los próximos cursos

Adaptación de las asignaturas básicas de primer curso de la ETSI Navales de la UPM: Primeras experiencias

En el marco de la reforma de las titulaciones con motivo de la puesta en marcha del Espacio Europeo de Educación Superior, un grupo de profesores hemos decidido coordinar todas las asignaturas básicas de primer curso y una asignatura de segundo curso en la Escuela Técnica Superior de Ingenieros Navales de la Universidad Politécnica de Madrid con el fin de dar una visión mas homogénea y compacta al alumno de lo que debe ser la formación básica del ingeniero. Para llevar a cabo dicho fin, la Universidad nos ha concedido un Proyecto de Innovación Educativa en la convocatoria 2008 para poder alcanzar una serie de objetivos en el curso 2008-2009, como son la coordinación de todas las asignaturas básicas de primer curso, la aplicación de nuevas metodologías en la práctica educativa, y una mejor adaptación de los alumnos de nuevo ingreso

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

Spatiotemporal Characteristics of the Largest HIV-1 CRF02_AG Outbreak in Spain: Evidence for Onward Transmissions

Background and Aim: The circulating recombinant form 02_AG (CRF02_AG) is the predominant clade among the human immunodeficiency virus type-1 (HIV-1) non-Bs with a prevalence of 5.97% (95% Confidence Interval-CI: 5.41–6.57%) across Spain. Our aim was to estimate the levels of regional clustering for CRF02_AG and the spatiotemporal characteristics of the largest CRF02_AG subepidemic in Spain.Methods: We studied 396 CRF02_AG sequences obtained from HIV-1 diagnosed patients during 2000–2014 from 10 autonomous communities of Spain. Phylogenetic analysis was performed on the 391 CRF02_AG sequences along with all globally sampled CRF02_AG sequences (N = 3,302) as references. Phylodynamic and phylogeographic analysis was performed to the largest CRF02_AG monophyletic cluster by a Bayesian method in BEAST v1.8.0 and by reconstructing ancestral states using the criterion of parsimony in Mesquite v3.4, respectively.Results: The HIV-1 CRF02_AG prevalence differed across Spanish autonomous communities we sampled from (p < 0.001). Phylogenetic analysis revealed that 52.7% of the CRF02_AG sequences formed 56 monophyletic clusters, with a range of 2–79 sequences. The CRF02_AG regional dispersal differed across Spain (p = 0.003), as suggested by monophyletic clustering. For the largest monophyletic cluster (subepidemic) (N = 79), 49.4% of the clustered sequences originated from Madrid, while most sequences (51.9%) had been obtained from men having sex with men (MSM). Molecular clock analysis suggested that the origin (tMRCA) of the CRF02_AG subepidemic was in 2002 (median estimate; 95% Highest Posterior Density-HPD interval: 1999–2004). Additionally, we found significant clustering within the CRF02_AG subepidemic according to the ethnic origin.Conclusion: CRF02_AG has been introduced as a result of multiple introductions in Spain, following regional dispersal in several cases. We showed that CRF02_AG transmissions were mostly due to regional dispersal in Spain. The hot-spot for the largest CRF02_AG regional subepidemic in Spain was in Madrid associated with MSM transmission risk group. The existence of subepidemics suggest that several spillovers occurred from Madrid to other areas. CRF02_AG sequences from Hispanics were clustered in a separate subclade suggesting no linkage between the local and Hispanic subepidemics

Novel genes and sex differences in COVID-19 severity.

Here we describe the results of a genome-wide study conducted in 11 939 COVID-19 positive cases with an extensive clinical information that were recruited from 34 hospitals across Spain (SCOURGE consortium). In sex-disaggregated genome-wide association studies for COVID-19 hospitalization, genome-wide significance (p < 5x10-8) was crossed for variants in 3p21.31 and 21q22.11 loci only among males (p = 1.3x10-22 and p = 8.1x10-12, respectively), and for variants in 9q21.32 near TLE1 only among females (p = 4.4x10-8). In a second phase, results were combined with an independent Spanish cohort (1598 COVID-19 cases and 1068 population controls), revealing in the overall analysis two novel risk loci in 9p13.3 and 19q13.12, with fine-mapping prioritized variants functionally associated with AQP3 (p = 2.7x10-8) and ARHGAP33 (p = 1.3x10-8), respectively. The meta-analysis of both phases with four European studies stratified by sex from the Host Genetics Initiative confirmed the association of the 3p21.31 and 21q22.11 loci predominantly in males and replicated a recently reported variant in 11p13 (ELF5, p = 4.1x10-8). Six of the COVID-19 HGI discovered loci were replicated and an HGI-based genetic risk score predicted the severity strata in SCOURGE. We also found more SNP-heritability and larger heritability differences by age (<60 or ≥ 60 years) among males than among females. Parallel genome-wide screening of inbreeding depression in SCOURGE also showed an effect of homozygosity in COVID-19 hospitalization and severity and this effect was stronger among older males. In summary, new candidate genes for COVID-19 severity and evidence supporting genetic disparities among sexes are provided
