Prévalence et facteurs de risque d'obésité et de surpoids dans une population de chiens sains présentés en médecine préventive à l’École Nationale Vétérinaire de Toulouse et à l’École Nationale Vétérinaire de Maisons-Alfort

L’objectif de cette étude, menée entre Septembre et Juillet 2021, était de déterminer la prévalence et les facteurs de risque d’excès pondéral dans une population de chiens sains présentés en consultation de médecine préventive dans les Écoles Nationales Vétérinaires de Toulouse et Maisons Alfort. Les informations sur le mode de vie et les habitudes alimentaires ont été récoltées grâce à un questionnaire. L’état corporel et musculaire a été évalué, par le personnel formé, puis comparé aux notes attribuées par le propriétaire. Les prévalences de surpoids et d’obésité ont été de 33,9% et de 2,3%. Le risque d’excès pondéral augmente avec l’âge (OR=3,7 pour la classe d’âge 7 à 12 ans ; p<0,001), chez les femelles (OR=2,4 ; p<0,001), les chiens stérilisés (OR=2,56 ; p<0,05), ceux rarement vermifugés (OR=6,6 ; p<0,05) et diminue quand l’aliment est acheté en clinique vétérinaire (OR=0,17 ; p<0,001). Une tendance à la sous-estimation du score corporel par les propriétaires a été observée

Dynamic proofs of retrievability with low server storage

Proofs of Retrievability (PoRs) are protocols which allow a client to store data remotely and to efficiently ensure, via audits, that the entirety of that data is still intact. A dynamic PoR system also supports efficient retrieval and update of any small portion of the data. We propose new, simple protocols for dynamic PoR that are designed for practical efficiency, trading decreased persistent storage for increased server computation, and show in fact that this tradeoff is inherent via a lower bound proof of time-space for any PoR scheme. Notably, ours is the first dynamic PoR which does not require any special encoding of the data stored on the server, meaning it can be trivially composed with any database service or with existing techniques for encryption or redundancy. Our implementation and deployment on Google Cloud Platform demonstrates our solution is scalable: for example, auditing a 1TB file takes just less than 5 minutes and costs less than $0.08 USD. We also present several further enhancements, reducing the amount of client storage, or the communication bandwidth, or allowing public verifiability, wherein any untrusted third party may conduct an audit

Mycobacterium tuberculosis Lipolytic Enzymes as Potential Biomarkers for the Diagnosis of Active Tuberculosis

BACKGROUND: New diagnosis tests are urgently needed to address the global tuberculosis (TB) burden and to improve control programs especially in resource-limited settings. An effective in vitro diagnostic of TB based on serological methods would be regarded as an attractive progress because immunoassays are simple, rapid, inexpensive, and may offer the possibility to detect cases missed by standard sputum smear microscopy. However, currently available serology tests for TB are highly variable in sensitivity and specificity. Lipolytic enzymes have recently emerged as key factors in lipid metabolization during dormancy and/or exit of the non-replicating growth phase, a prerequisite step of TB reactivation. The focus of this study was to analyze and compare the potential of four Mycobacterium tuberculosis lipolytic enzymes (LipY, Rv0183, Rv1984c and Rv3452) as new markers in the serodiagnosis of active TB. METHODS: Recombinant proteins were produced and used in optimized ELISA aimed to detect IgG and IgM serum antibodies against the four lipolytic enzymes. The capacity of the assays to identify infection was evaluated in patients with either active TB or latent TB and compared with two distinct control groups consisting of BCG-vaccinated blood donors and hospitalized non-TB individuals. RESULTS: A robust humoral response was detected in patients with active TB whereas antibodies against lipolytic enzymes were infrequently detected in either uninfected groups or in subjects with latent infection. High specifity levels, ranging from 93.9% to 97.5%, were obtained for all four antigens with sensitivity values ranging from 73.4% to 90.5%, with Rv3452 displaying the highest performances. Patients with active TB usually exhibited strong IgG responses but poor IgM responses. CONCLUSION: These results clearly indicate that the lipolytic enzymes tested are strongly immunogenic allowing to distinguish active from latent TB infections. They appear as potent biomarkers providing high sensitivity and specificity levels for the immunodiagnosis of active TB

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 60 109 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: ‘Typical’ 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 (≤ 18 years: 69, 48, 23; 85%), older adults (≥ 70 years: 61, 62, 65; 90%), and women (66, 66, 64; 90%; vs. men 71, 70, 67; 93%, each P &lt; 0.001). 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

« Agua de rosas » de Lila Downs : une expérience de vision

Dans son album Entre copa y copa, canciones de cantina(2006), Lila Downs, une artiste mexico-étatsunienne de musique du monde, propose une composition intitulée « Agua de rosas », dans laquelle l’artiste prend pour thème le bain de roses que des guérisseuses zapotèques de Juchitán de Zaragoza, dans l’Etat d’Oaxaca, Mexique, lui ont donné pour qu’elle se détende et soigne ses peines. Cette chanson correspond également à un éloge funèbre adressé à Idalia Linares Sánchez, une amie personnelle. Idalia Linares représentait un membre actif de la Coalición Obrera, Campesina y Estudiantil del Istmo, une association indienne qui remporte les élections municipales de Juchitán en 1981. Un entretien avec la fille d’Idalia Linares, Marlene Linares, qui a notamment connu une expérience migratoire aux Etats-Unis, ainsi que le discours poétique de Lila Downs nous amèneront à nous interroger sur la vie et la subjectivité des femmes zapotèques, sur les continuités et les ruptures entre deux générations, sur les tensions entre l’ancien et le moderne.In her album Entre copa y copa, canciones de cantina (2006), Lila Downs, a Mexican-American artist of world music, proposes a composition entitled « Agua de rosas », a song in which the artist takes for topic the bath of roses that Zapotec healers of Juchitán de Zaragoza, in Oaxaca’s State in Mexico, gave her so that she relaxes and lightens hers sorrows. This song also corresponds to a funeral oration addressed to Idalia Linares Sánchez, a personal friend. Idalia Linares represented an active member of the Coalición Obrera, Campesina y Estudiantil del Istmo, an Indian association which wins Juchitán’s municipal elections in 1981. A discussion with Idalia Linares’ daughter, Marlene Linares, which especially knew a migratory experiment in the United States, as well as Lila Downs’ poetic discourse will lead us to wonder about the life and the subjectivity of the Zapotec women, about continuities and ruptures between two generations, about the tensions between the ancient and the modern

Récits sur la folie : la légende mexicaine de la Llorona

Le mythe de la Llorona a inspiré de nombreuses artistes et écrivaines postmodernes hispano-américaines, qui ont converti cette Femme qui pleure mexicaine en une icône identitaire plus positive que dans la tradition orale classique. Cette approche à la fois intimiste et transnationale peut déjà s’observer dans la littérature chicana des années 80 et 90. Elle concerne désormais également des musiciennes telles que Lila Downs, chanteuse de musique du monde, ou des auteures issues d’autres groupes culturels, comme la chilienne Marcela Serrano (La Llorona, 2008)
