COVID-19 symptoms at hospital admission vary with age and sex: results from the ISARIC prospective multinational observational study
Background:
The ISARIC prospective multinational observational study is the largest cohort of hospitalized patients with COVID-19. We present relationships of age, sex, and nationality to presenting symptoms.
Methods:
International, prospective observational study of 60â109 hospitalized symptomatic patients with laboratory-confirmed COVID-19 recruited from 43 countries between 30 January and 3 August 2020. Logistic regression was performed to evaluate relationships of age and sex to published COVID-19 case definitions and the most commonly reported symptoms.
Results:
âTypicalâ symptoms of fever (69%), cough (68%) and shortness of breath (66%) were the most commonly reported. 92% of patients experienced at least one of these. Prevalence of typical symptoms was greatest in 30- to 60-year-olds (respectively 80, 79, 69%; at least one 95%). They were reported less frequently in children (â€â18 years: 69, 48, 23; 85%), older adults (â„â70 years: 61, 62, 65; 90%), and women (66, 66, 64; 90%; vs. men 71, 70, 67; 93%, each Pâ<â0.001). The most common atypical presentations under 60 years of age were nausea and vomiting and abdominal pain, and over 60 years was confusion. Regression models showed significant differences in symptoms with sex, age and country.
Interpretation:
This international collaboration has allowed us to report reliable symptom data from the largest cohort of patients admitted to hospital with COVID-19. Adults over 60 and children admitted to hospital with COVID-19 are less likely to present with typical symptoms. Nausea and vomiting are common atypical presentations under 30 years. Confusion is a frequent atypical presentation of COVID-19 in adults over 60 years. Women are less likely to experience typical symptoms than men
Collections de marionnettes et politiques du spectacle vivant
On assiste, depuis une quinzaine dâannĂ©es, Ă un accroissement notable de la visibilitĂ© des collections de marionnettes en France. Le symbole en est sans doute la mise en ligne du Portail des arts de la marionnette en 2011, portĂ© par lâInstitut international de la marionnette, en partenariat avec des institutions patrimoniales, des thĂ©Ăątres, des compagnies ou des associations professionnelles, et qui prĂ©sente, conjointement, la crĂ©ation, les artistes contemporains et les collections patrimoniales. Au regard de ce contexte fortement incitatif, et Ă partir dâune enquĂȘte auprĂšs des principales institutions dĂ©tentrices de collections marionnettiques, comme de figures majeures dans le champ des arts de la marionnette, lâarticle envisage les stratĂ©gies de dĂ©veloppement et de valorisation des collections mises en Ćuvre dans les principales institutions patrimoniales ou en dehors du champ proprement musĂ©al. Il examine lâinflĂ©chissement des politiques dâacquisition au regard des principes qui ont prĂ©valu pour les collections fondatrices de ces institutions et les effets quâinduit lâinfluence croissante des acteurs professionnels de la marionnette (syndicats, associations professionnelles, festivals et lieux de formation) en matiĂšre dâexpertise et de soutien logistique, Ă la fois en termes de dĂ©finition du champ (vers les artistes contemporains de la marionnette de crĂ©ation, plutĂŽt que vers la marionnette traditionnelle, Ă lâĂ©chelle tant rĂ©gionale que mondiale), de hiĂ©rarchisation des prioritĂ©s, de choix du corpus et de finalitĂ©s.In the past fifteen years, there has been a notable gain in visibility for puppetry collections in France. A symbol of this is undoubtedly the creation of the online Portal for Puppetry Arts in 2011, supported by the International Institute of Puppetry in partnership with heritage institutions, theaters, troupes and professional associations, presenting original work, contemporary artists and heritage collections. In the light of this favorable context, and on the basis of a study of the principal institutions with puppetry holdings and major figures in the world of puppetry arts, this article lays out some of the development and promotion strategies at work in major heritage institutions and those out of the scope of museums. It examines the shifts involved in acquisition policy with regards to the principles that prevailed in the formation of these institutionsâ first holdings, and the effects that the growing influence of puppetry professionals (unions, professional associations, festivals and training programs) have, in terms of expertise and logistics, on the definition of the field (leaning more towards to original pieces of puppetry by contemporary artists than to traditional puppetry, on a global and regional scale), prioritization, choice of corpus and objectives.En los Ășltimos quince años, se ha evidenciado un notable incremento en la visibilidad de las colecciones de tĂteres y marionetas en Francia. El sĂmbolo de aquello es sin duda el lanzamiento del Portal de las Artes del TĂtere y la Marioneta en 2011, realizado por el Instituto Internacional del TĂtere y la Marioneta, en colaboraciĂłn con instituciones patrimoniales, teatros, compañĂas o asociaciones profesionales, y que presenta, conjuntamente, la creaciĂłn, los artistas contemporĂĄneos y las colecciones patrimoniales. Considerando este contexto tan alentador, y a partir de un estudio de las principales instituciones que poseen colecciones de tĂteres y marionetas, asĂ como de las principales figuras en el campo de las artes del tĂtere y la marioneta, el artĂculo aborda las estrategias de desarrollo y valorizaciĂłn de las colecciones puestas en marcha en las principales instituciones patrimoniales o fuera del ĂĄmbito propiamente museĂstico. Se examinan la reorientaciĂłn de las polĂticas de adquisiciĂłn con respecto a los principios que han prevalecido en cuanto a las colecciones fundadoras de estas instituciones y los efectos de la creciente influencia de los actores profesionales del tĂtere y la marioneta (sindicatos, asociaciones profesionales, festivales y centros de formaciĂłn) en tĂ©rminos de experticia tĂ©cnica y apoyo logĂstico, tanto en lo que se refiere a la definiciĂłn del campo (hacia los creativos titiriteros y marionetistas contemporĂĄneos, en lugar de hacia el tĂtere y la marioneta tradicional, tanto a escala regional como mundial), a la jerarquizaciĂłn de prioridades, la elecciĂłn del corpus y los propĂłsitos

LâopĂ©ra baroque sur la scĂšne musĂ©ale, ou lâopĂ©ra autrement : Barockissimo au Centre national du costume de scĂšne et de la scĂ©nographie
Barockissimo, les Arts Florissants en scĂšne est une exposition de costumes dĂ©diĂ©e aux Arts Florissants au Centre national du costume de scĂšne et de la scĂ©nographie en 2016. Notre analyse, qui mĂȘle approches esthĂ©tiques et sĂ©mioâpragmatiques, cherche Ă mettre en Ă©vidence les finalitĂ©s et les modalitĂ©s de la mise en exposition de lâopĂ©ra baroque proposĂ©e par les commissaires Martine Kahane et Catherine Massip et les scĂ©nographes Alain Batifoulier et Simon de Tovar. LâopĂ©ra baroque y emprunte le costume des Arts Florissants, au point quâil en est indissociable, dans une mission de mĂ©diation culturelle : il sâagit de populariser lâopĂ©ra et dâinitier le visiteur nĂ©ophyte Ă la scĂšne opĂ©ratique. Pour ce faire, les expositeurs Ă©laborent, pour donner corps Ă lâopĂ©ra baroque, une pseudo-scĂšne, sur laquelle ils invitent symboliquement les visiteurs Ă monter, pour mieux les inciter, auâdelĂ , Ă passer les portes dâune maison dâopĂ©ra. Ă travers lâexpoÂsition de costumes, dâĂ©lĂ©ments de dĂ©cors et de mĂ©dias associĂ©s (textes, extraits vidĂ©os et audio), les expositeurs contribuent douÂblement Ă patrimonialiser les Arts Florissants et Ă en consacrer le rĂŽle de passeurs privilĂ©giĂ©s.âBarockissimo, Les Arts Florissants on stageâ, is an exhibition of stage costumes dedicated in 2016 to the Arts FloÂrissants, the baroque ensemble created by William Christie, at the National Center for Stage Costume. It was curated by Martine Kahane and Catherine Massip, and designed by Alain Batifoulier and Simon de Tovar. Our analysis, based both on aesthetics and semio-pragmatic approaches, aims to highlight the purposes and processes of this exhibition in which the Arts Florissants appear as the insepaÂrable image of the baroque opera, borrowing its costumes and undertaking a mission of cultural mediation: to popularize opera and introduce neophyte visitors to the operatic stage. Visitors are symbolically invited to get up on a pseudo-stage so that in the future they will not hesitate to push open the doors of Opera houses. The exhibition presents costumes, pieces of stage sets, and related assoÂciated media such as texts, videos and audio documents. It contriÂbutes to both commemorate the Arts Florissants ensemble and recognize their role as baroque operaâs most faithful interpreters.Barockissimo, les Arts Florissants en escena es una exposiciĂłn de vestuario dedicada a las Arts Florissants en el Centro Nacional del Vestuario de escena y de la escenografĂa en 2016. Nuestro anĂĄlisis, el cual articula enfoques estĂ©ticos y semio-pragmĂĄticos, busca dar a conocer las finalidades y las modaÂlidades de la exposiciĂłn de la Ăłpera barroca propuesta por las curadoras Martine Kahane y Catherine Massip y los escenĂłgrafos Alain Batifoulier y SimĂłn de Tovar. La Ăłpera barroca adopta el vestuario de las Arts Florissants, volviĂ©ndolos inseparables, durante una misiĂłn de mediaciĂłn cultural : se trata de popularizar la Ăłpera y de iniciar al visitante neĂłfito a la escena operĂĄtica. Para esto, los expositores elaboran una pseudo-escena, que le da cuerpo a la Ăłpera barroca y a la cual los visitantes estĂĄn invitados a subir de forma simbĂłlica, con el objetivo de incitarles a entrar en una casa de Ăłpera e ir mĂĄs allĂĄ. A travĂ©s de la exposiciĂłn de vestuaÂrio, de elementos de decoraciĂłn y de medios asociados (textos, extractos de audio y vĂdeo), los expositores contribuyen dobleÂmente a patrimonializar las Arts Florissants y a consagrar el rol de los intermediarios privilegiados

Larval density in the invasive Drosophila suzukii : immediate and delayed effects on life-history traits
Abstract The immediate and delayed effects of density are key in determining population dynamics, since they can positively or negatively affect the fitness of individuals. These effects have great relevance for polyphagous insects for which immature stages develop within a single site of finite feeding resources. Drosophila suzukii is a crop pest that induces severe economic losses for agricultural production, however little is known about the effects of density on its life-history traits. In the present study, we (i) investigated the egg distribution resulting from femalesâ egg-laying strategy and (ii) tested the immediate and delayed effects of larval density on emergence rate, development time, sex ratio of offspring, fecundity and adult size (a range of 1 to 50 larvae was used). We showed that most of fruits contain several eggs and aggregate of eggs of high density can be found in some fruits. This high density has no immediate effects on the emergence rate, but has effect on larval developmental time. This trait was involved in a trade-off with adult life-history traits: the larval development was reduced as larval density increased, but smaller and less fertile adults were produced. Our results should help to better understand the population dynamics of this species and to develop more successful control programs
Nano-Structured Materials under Irradiation: Oxide Dispersion-Strengthened Steels
International audienceOxide dispersion-strengthened materials are reinforced by a (Y, Ti, O) nano-oxide dispersion and thus can be considered as nanostructured materials. In this alloy, most of the nanoprecipitates are (Y, Ti, O) nano-oxides exhibiting a YTiO pyrochlore-like structure. However, the lattice structure of the smallest oxides is difficult to determine, but it is likely to be close to the atomic structure of the host matrix. Designed to serve in extreme environmentsâi.e., a nuclear power plantâthe challenge for ODS steels is to preserve the nano-oxide dispersion under irradiation in order to maintain the excellent creep properties of the alloy in the reactor. Under irradiation, the nano-oxides exhibit different behaviour as a function of the temperature. At low temperature, the nano-oxides tend to dissolve owing to the frequent ballistic ejection of the solute atoms. At medium temperature, the thermal diffusion balances the ballistic dissolution, and the nano-oxides display an apparent stability. At high temperature, the nano-oxides start to coarsen, resulting in an increase in their size and a decrease in their number density. If the small nano-oxides coarsen through a radiation-enhanced Ostwald ripening mechanism, some large oxides disappear to the benefit of the small ones through a radiation-induced inverse Ostwald ripening. In conclusion, it is suggested that, under irradiation, the nano-oxide dispersion prevails over dislocations, grain boundaries and free surfaces to remove the point defects created by irradiation
