Psicología de las organizaciones y del trabajo. Apuestas de investigación II

El presente volumen condensa y sintetiza lo que va siendo contemporáneamente la POT colombiana, en particular, y latinoamericana, en general, que aparece como un reflejo y una adaptación de la que se está desarrollando globalmente según cánones dictados desde otras latitudes socioeconómicas, políticas y culturales, pero también como reacción a ella y como autoafirmación. Ello no constituye un ejemplar de texto anticolonial, sino más bien un manifiesto antietnocéntrico al presentar e interpretar la realidad investigada en el marco de sus propios parámetros socioculturales, sin que estos sean considerados necesariamente claves universales para la comprensión de otras realidades ajenas y exóticas. Y esta es una de sus principales contribuciones generales, porque marca un estilo distinto de hacer POT al enfatizar el aspecto idiosincrático de los fenómenos y procesos de que se ocupa y haciéndolo así, señala un horizonte que no deben perder de vista la disciplina y la profesión, si no quieren repetir viejos errores de su pasado reciente derivados de la minimización de la relatividad histórico-cultural de su campo y su objeto. A escala global y local, resta un largo camino por progresar hacia una POT con mayor fundamentación epistemológica, más articulación interdisciplinaria y multiprofesional, relevancia social, elaboración teórica, calidad y diversidad metodológicas y reflexividad autocrítica que resitúe en el centro del quehacer científico y profesional el marco de referencia axiológico, étho-politico y deontológico. Este libro es un paso significativo en esta dirección.Universidad de San Buenaventura - Cal

The risk of COVID-19 death is much greater and age dependent with type I IFN autoantibodies

International audienceSignificance There is growing evidence that preexisting autoantibodies neutralizing type I interferons (IFNs) are strong determinants of life-threatening COVID-19 pneumonia. It is important to estimate their quantitative impact on COVID-19 mortality upon SARS-CoV-2 infection, by age and sex, as both the prevalence of these autoantibodies and the risk of COVID-19 death increase with age and are higher in men. Using an unvaccinated sample of 1,261 deceased patients and 34,159 individuals from the general population, we found that autoantibodies against type I IFNs strongly increased the SARS-CoV-2 infection fatality rate at all ages, in both men and women. Autoantibodies against type I IFNs are strong and common predictors of life-threatening COVID-19. Testing for these autoantibodies should be considered in the general population

Rare predicted loss-of-function variants of type I IFN immunity genes are associated with life-threatening COVID-19

BackgroundWe previously reported that impaired type I IFN activity, due to inborn errors of TLR3- and TLR7-dependent type I interferon (IFN) immunity or to autoantibodies against type I IFN, account for 15-20% of cases of life-threatening COVID-19 in unvaccinated patients. Therefore, the determinants of life-threatening COVID-19 remain to be identified in similar to 80% of cases.MethodsWe report here a genome-wide rare variant burden association analysis in 3269 unvaccinated patients with life-threatening COVID-19, and 1373 unvaccinated SARS-CoV-2-infected individuals without pneumonia. Among the 928 patients tested for autoantibodies against type I IFN, a quarter (234) were positive and were excluded.ResultsNo gene reached genome-wide significance. Under a recessive model, the most significant gene with at-risk variants was TLR7, with an OR of 27.68 (95%CI 1.5-528.7, P=1.1x10(-4)) for biochemically loss-of-function (bLOF) variants. We replicated the enrichment in rare predicted LOF (pLOF) variants at 13 influenza susceptibility loci involved in TLR3-dependent type I IFN immunity (OR=3.70[95%CI 1.3-8.2], P=2.1x10(-4)). This enrichment was further strengthened by (1) adding the recently reported TYK2 and TLR7 COVID-19 loci, particularly under a recessive model (OR=19.65[95%CI 2.1-2635.4], P=3.4x10(-3)), and (2) considering as pLOF branchpoint variants with potentially strong impacts on splicing among the 15 loci (OR=4.40[9%CI 2.3-8.4], P=7.7x10(-8)). Finally, the patients with pLOF/bLOF variants at these 15 loci were significantly younger (mean age [SD]=43.3 [20.3] years) than the other patients (56.0 [17.3] years; P=1.68x10(-5)).ConclusionsRare variants of TLR3- and TLR7-dependent type I IFN immunity genes can underlie life-threatening COVID-19, particularly with recessive inheritance, in patients under 60 years old
