    La publicación del poema épico de Joaquín de Virués 'El Cerco de Zamora' (1832) supone un episodio más de la polémica del autor con los ilusrrados españoles. El poema va precedido de un "Discurso crítico-apologético" en el que Virués se opone frontalmente a las tesis ilustradas sobre la poesía: rechaza las poéticas, la imitación y los modelos clásicos; defiende la poesía natural y niega que exista un lenguaje poético; ataca a la academia y a los neoclásicos. Las tesis de Virués están cerca del romanticismo; lo cual revela que en el debate literario de los años 20 y 30 del siglo XIX había más opiniones y divergencias de las que habitualmente se cree. The publicatio n of the epic poem by Joaquín de Virués 'El Cerco de Zamora' (1832) is one step in Virués' controverses against the Spanish "ilustrados". The poem was preceded by a "Discurso crítico-apologético" in wich Virués disagrees with the opinion of the “ilustrados” about poetry: he rejects the treatises on poetics, the imitation and the classic stereotypes; defends natural poetry and refuses the existence of a specific poetic language; and attacks the Academy and the neoclassic poets. Virués' positions clase to Romanticism shows thar rhe literary debate of the 1820's and 1830's is more complex than is usually thought

    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

    Trabajo presentado en la 12ª Reunión de la Red Española de Bacterias Lácticas (RedBAL), celebrada en Sevilla (España) del 17 al 18 de mayo de 2018.Y presentado también en el 7th International Human Microbiome Congress, IHMC, celebrado en County Kerry (Irlanda) del 28 al 26 de junio de 2018n los últimos años se está revelando la relación entre el metabolismo de sales biliares y el colesterol, la microbiota intestinal y su implicación en la salud. A diferencia de otras localizaciones, el microbioma del tracto biliar apenas ha sido estudiado. En este trabajo se ha realizado un análisis metagenómico filogenético y funcional de muestras de bilis humana, además de un análisis metabolómico, con el fin de caracterizar el microbioma biliar de donantes de hígado y pacientes con colelitiasis, e identificar posibles disbiosis asociadas a esta patología. Se obtuvieron muestras de bilis de donantes de hígado y pacientes con colelitiasis, de las que se extrajo el ADN biliar siguiendo un protocolo optimizado. Se llevó a cabo la secuenciación masiva de amplicones del ADNr 16S mediante la tecnología Illumina. Además, se realizó secuenciación masiva por shotgun y análisis de metagenómica funcional de tres muestras de bilis de sujetos sanos. El análisis metabolómico se realizó utilizando técnicas de NMR. Los resultados mostraron una gran diversidad microbiana presente en este tipo de muestras, con presencia de 4 filos mayoritarios: Firmicutes, Bacteriodetes, Actinobacteria y Proteobacteria. El análisis estadístico mostró diferencias significativas en la abundancia relativa de diversos taxones presentes en la bilis de ambos grupos. En concreto, secuencias de la familia Propionibacteriaceae fueron más abundantes en la bilis de los donantes de hígado, mientras que en pacientes con colelitiasis fueron más frecuentes las de las familias Bacteroidaceae, Prevotellaceae, Porphyromonadaceae y Veillonellaceae. El análisis funcional mostró que la asignación a las principales categorías funcionales del COG es similar a la del microbioma intestinal humano. Por último, el análisis metabolómico nos permitió asociar diferentes perfiles metabólicos a los grupos de individuos objeto de estudio.This work was financed by the Spanish “Plan Nacional I+D+i” through the project AGL2013-44761-PPeer reviewe

    Prevalence of reduced lung diffusing capacity and CT scan findings in smokers without airflow limitation: a population-based study

    No full text
    Background Population distribution of reduced diffusing capacity of the lungs for carbon monoxide (DLCO) in smokers and main consequences are not properly recognised. The objectives of this study were to describe the prevalence of reduced DLCO in a population-based sample of current and former smoker subjects without airflow limitation and to describe its morphological, functional and clinical implications.Methods A sample of 405 subjects aged 40 years or older with postbronchodilator forced expiratory volume in 1 s/forced vital capacity (FVC) >0.70 was obtained from a random population-based sample of 9092 subjects evaluated in the EPISCAN II study. Baseline evaluation included clinical questionnaires, exhaled carbon monoxide (CO) measurement, spirometry, DLCO determination, 6 min walk test, routine blood analysis and low-dose CT scan with evaluation of lung density and airway wall thickness.Results In never, former and current smokers, prevalence of reduced DLCO was 6.7%, 14.4% and 26.7%, respectively. Current and former smokers with reduced DLCO without airflow limitation were younger than the subjects with normal DLCO, and they had greater levels of dyspnoea and exhaled CO, greater pulmonary artery diameter and lower spirometric parameters, 6 min walk distance, daily physical activity and plasma albumin levels (all p<0.05), with no significant differences in other chronic respiratory symptoms or CT findings. FVC and exhaled CO were identified as independent risk factors for low DLCO.Conclusion Reduced DLCO is a frequent disorder among smokers without airflow limitation, associated with decreased exercise capacity and with CT findings suggesting that it may be a marker of smoking-induced early vascular damage.Trial registration number NCT03028207

    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

    The PREDICTS project-Projecting Responses of Ecological Diversity In Changing Terrestrial Systems (www.predicts.org.uk)-has collated from published studies a large, reasonably representative database of comparable samples of biodiversity from multiple sites that differ in the nature or intensity of human impacts relating to land use. We have used this evidence base to develop global and regional statistical models of how local biodiversity responds to these measures. We describe and make freely available this 2016 release of the database, containing more than 3.2 million records sampled at over 26,000 locations and representing over 47,000 species. We outline how the database can help in answering a range of questions in ecology and conservation biology. To our knowledge, this is the largest and most geographically and taxonomically representative database of spatial comparisons of biodiversity that has been collated to date; it will be useful to researchers and international efforts wishing to model and understand the global status of biodiversity
