Autoantibodies against type I IFNs in patients with critical influenza pneumonia
In an international cohort of 279 patients with hypoxemic influenza pneumonia, we identified 13 patients (4.6%) with autoantibodies neutralizing IFN-alpha and/or -omega, which were previously reported to underlie 15% cases of life-threatening COVID-19 pneumonia and one third of severe adverse reactions to live-attenuated yellow fever vaccine. Autoantibodies neutralizing type I interferons (IFNs) can underlie critical COVID-19 pneumonia and yellow fever vaccine disease. We report here on 13 patients harboring autoantibodies neutralizing IFN-alpha 2 alone (five patients) or with IFN-omega (eight patients) from a cohort of 279 patients (4.7%) aged 6-73 yr with critical influenza pneumonia. Nine and four patients had antibodies neutralizing high and low concentrations, respectively, of IFN-alpha 2, and six and two patients had antibodies neutralizing high and low concentrations, respectively, of IFN-omega. The patients' autoantibodies increased influenza A virus replication in both A549 cells and reconstituted human airway epithelia. The prevalence of these antibodies was significantly higher than that in the general population for patients 70 yr of age (3.1 vs. 4.4%, P = 0.68). The risk of critical influenza was highest in patients with antibodies neutralizing high concentrations of both IFN-alpha 2 and IFN-omega (OR = 11.7, P = 1.3 x 10(-5)), especially those <70 yr old (OR = 139.9, P = 3.1 x 10(-10)). We also identified 10 patients in additional influenza patient cohorts. Autoantibodies neutralizing type I IFNs account for similar to 5% of cases of life-threatening influenza pneumonia in patients <70 yr old
Vieillir ? Et alors !: Vivons mieux, vivons vieux !
National audienceQuâest-ce que la vieillesse ? Comment vieillit-on ? Peut-on ĂȘtre vieux et heureux ? Que mettre en place pour accompagner une personne ĂągĂ©e ? Face Ă des images souvent stĂ©rĂ©otypĂ©es et nĂ©gatives, des chercheurs et des spĂ©cialistes des personnes ĂągĂ©es ont souhaitĂ© porter une rĂ©flexion nouvelle sur nos reprĂ©sentations.Nathalie Bailly et Kristell Pothier nous offrent ici un ouvrage pluridisciplinaire qui permet dâĂ©clairer les diffĂ©rentes facettes de cette pĂ©riode de la vie avec recul. Acteurs de terrain et chercheurs y croisent leur regard sur la notion de vieillissement, quâil soit pathologique ou non. Ce travail collectif sâinscrit dans une vision positive des processus de vieillissement en privilĂ©giant les ressources et potentialitĂ©s de chaque personne.Puissions-nous, grĂące Ă ce guide, mieux prĂ©parer et apprĂ©hender notre propre vieillissement : car oui, vieillir, cela sâapprend et sâanticipe

Libre accĂšs et frais de publication associĂ©s (Articles Processing Charges) : une Ă©tude de cas de la production scientifique des Ă©tablissements dâenseignement supĂ©rieur et de recherche orlĂ©anais
International audienceOne of the corollaries of the open access movement (OA) has been the setting upof open access journals, with the occurrence, for some of them, of publication fees (ArticleProcessing Charges) that authors must pay to publish. The aim of this study is twofold: â tocharacterize the articles produced by the researchers of the higher education and researchinstitutions of Orleans (France) in 2016 in relation to the OA (presence on the open archiveHAL, characteristics of the journals in which these articles have been published, APC theytheoretically require. . .); â to record the actual APCs paid by these matching institutions. Themain results of this study show that the hybrid model is becoming more and more popular amongpublishers (for 83.6% of the 923 articles studied, the authors had the possibility to choose thehybrid option). Regarding that hybrid option, even if it was offered to authors, it was onlychosen in 10% of cases, the number of articles published under this option accounted for 41.9%of articles published in open access. The APC expenses borne by the Orleans community arespread over only 23 articles (out of 923 published), and the actual amount spent (39,261 D ) is inthe end rather limited compared to the total amount spent for the acquisition of documentaryresources by institutions of comparable size to those of the Orleans community. The resultspresented in this study offer a useful comparison with previous works, for a better understandingof the complex problematics of OA and its resulting APCs.© 2019 Elsevier Masson SAS. All rights reserved.Le mouvement « open access » (OA) a eu notamment pour consĂ©quence la mise enplace de revues en libre accĂšs, avec lâapparition, pour certaines dâentre elles, de frais de publi-cation (Article Processing Charges) que doivent acquitter les auteurs pour publier. Lâobjectif decette Ă©tude est double : â caractĂ©riser les articles produits par les chercheurs des Ă©tablis-sements dâenseignement supĂ©rieur et de recherche orlĂ©anais sur lâannĂ©e 2016 par rapport Ă lâOA (prĂ©sence sur lâarchive ouverte HAL, caractĂ©ristiques des revues dans lesquelles ont Ă©tĂ©publiĂ©s ces articles, APC quâelles imposent thĂ©oriquement. . .) ; â comptabiliser les APC rĂ©el-lement payĂ©s par ces mĂȘmes Ă©tablissements. Les principaux rĂ©sultats de cette Ă©tude mettenten Ă©vidence que le modĂšle hybride tend Ă sâimposer de plus en plus chez les Ă©diteurs (pour83,6 % des 923 articles Ă©tudiĂ©s, les auteurs avaient la possibilitĂ© de choisir lâoption hybride).Concernant lâoption hybride, mĂȘme si ââ lorsquâelle Ă©tait proposĂ©e aux auteurs ââ elle nâa Ă©tĂ©choisie que dans 10 % des cas, le nombre dâarticles publiĂ©s selon cette option reprĂ©sentait 41,9 %des articles publiĂ©s en libre accĂšs. Les dĂ©penses dâAPC prises en charge par la communautĂ©orlĂ©anaise se rĂ©partissent uniquement sur 23 articles (sur 923 publiĂ©s), et la somme dĂ©boursĂ©e (39 261 D ) est finalement assez limitĂ©e en regard des sommes totales dĂ©pensĂ©es pour lesacquisitions des ressources documentaires par des institutions de taille comparable Ă cellesde la communautĂ© orlĂ©anaise. Les rĂ©sultats prĂ©sentĂ©s dans cette Ă©tude offrent un Ă©lĂ©ment decomparaison utile par rapport Ă des travaux antĂ©rieurs, permettant de mieux apprĂ©hender laproblĂ©matique, complexe, de lâOA et des APC qui en dĂ©coulent
Associations Between Frailty and Inflammation, Physical, and Psycho-Social Health in Older Adults: A Systematic Review
International audienceFrailty is a complex geriatric syndrome with multifactorial associated mechanisms that need to be examined more deeply to help reverse the adverse health-related outcomes. Specific inflammatory and physical health markers have been associated with the onset of frailty, but the associations between these factors and psycho-social health outcomes seem less studied. This systematic review aimed to identify, in the same study design, the potential associations between frailty and markers of inflammation, and physical or psycho-social health. A literature search was performed from inception until March 2021 using Medline, Psycinfo, and EMBASE. Three raters evaluated the articles and selected 22 studies, using inclusion and exclusion criteria ( n = 17,373; 91.6% from community-dwelling samples). Regarding biomarkers, 95% of the included studies showed significant links between inflammation [especially the higher levels of C-reactive protein (CRP) and interleukin-6 (IL-6)], and frailty status. Approximately 86% of the included studies showed strong links between physical health decline (such as lower levels of hemoglobin, presence of comorbidities, or lower physical performance), and frailty status. At most, 13 studies among the 22 included ones evaluated psycho-social variables and mixed results were observed regarding the relationships with frailty. Results are discussed in terms of questioning the medical perception of global health, centering mostly on the physical dimension. Therefore, the development of future research studies involving a more exhaustive view of frailty and global (bio-psycho-social) health is strongly encouraged
Stereoselective Diversity-Oriented Solution and Solid-Phase Synthesis of Tetrahydroquinoline-Based Polycyclic Derivatives
A diversity-oriented solution and solid-phase synthesis of tetrahydroquinoline-based tricyclic derivatives has been achieved from enantiomerically pure, natural product-like bicyclic scaffold. The solution synthesis of enantiopure bicyclic scaffold was developed by asymmetric hetero Michael reaction. Our approach for the synthesis of polycyclic derivatives utilized regio- and stereoselective hetero Michael reaction and ringclosing metathesis as key steps in solution and on solid phase.NRC publication: Ye
