Le Coran en contexte(s) omeyyade(s) : introduction

International audienceThe historical context of the genesis of the Qurʾān is a central issue within the field of Islamic Studies dealing with the founding text of Islam – even more so that no consensus on an academic reconstruction of this context has been reached. To set the Qurʾān « within its context(s) » appear therefore as an adequate ground for dialogue between History and the study of the religion of Islam. This introduction first describes what is at stake within the early history of the Qurʾān, i.e. its composition and canonisation, and then evokes how these issues relate to the Umayyad context. The initial idea of the conference that took place in June 2021, which was to address this topic within the limited framework of Syria-Palestine during the Umayyad period (661-750), eventually led to the possibility of a multi-situated view on the Umayyad developments regarding the Qurʾān, through confronting the sources in their diversity, in a wider, imperial horizon.Le contexte historique de la genèse du Coran constitue une question centrale dans les recherches islamologiques sur le texte fondateur de l’islam, d’autant plus vive qu’il n’existe pas de consensus sur une reconstruction scientifique de ce contexte. Placer le Coran « en contexte(s) » apparaît donc comme un terrain propice au dialogue entre islamologie et histoire. Cette introduction revient d’abord sur les enjeux propres à l’histoire première du Coran, c’est-à-dire à sa composition et à sa canonisation, avant d’évoquer comment ces enjeux s’articulent au contexte omeyyade. L’idée initiale d’un colloque organisé en juin 2021, qui consistait à appréhender l’histoire du Coran dans le contexte de la Syrie-Palestine à l’époque omeyyade (661-750), a finalement ouvert à la possibilité d’un regard multi-situé sur les développements omeyyades autour du Coran, à travers la confrontation des sources dans leur diversité et l’élargissement à un horizon impérial

Rapport de la tranche 2016 de la convention ONF/Irstea Nogent 2016-2018 sur l'étude des peuplements mélangés. La convention comprends trois axes principaux : la modélisation des mélanges à large échelle à partir des données d'inventaire, les études à partir du dispositif OPTMix, une prospective sur la gestion des chênaies irrégulière et des chênaies en contexte hydromorphe

Preliminary Report on the XIVth and XVth Campaigns at Larsa

International audienceIn 2019, fieldwork resumed at Larsa for two seasons of one month each. Several complementary surveys were undertaken kassite period aken that change our understanding of the site, revealing in particular part of the network of channels supplying the city. The excavations focused on the sector north of the E-Babbar, the temple of the Sun-God Shamash, patron deity of Larsa, whose reoccupation in the Hellenistic period seems more important than expected.Two buildings are being explored, B48 and B50. B48 is a large Hellenistic house (650 sq. m.) part of a well-planned neighborhood. In trench B50, below a very fragmentary Hellenistic temple, lay a major temple of the Old-Babylonian city, that remains to be identified. It is provided with massive mudbrick walls (5.6m wide at most) preserved in height up to the first storey of the building in some rooms (4.5m high). We give here a first brief account of our results, still in processing

Validation of a screening algorithm for hepatic fibrosis by Doppler ultrasound and elastography in a general population

Background Early detection can prevent the initial stages of fibrosis from progressing to cirrhosis. Purpose To evaluate an algorithm combining three echographic indicators and elastographic measurements to screen for hepatic fibrosis in an unselected population. Material and Methods From May 2017 to June 2018, all patients with no history and no known chronic liver disease who were referred for an ultrasound (US) were prospectively included in eight hospitals. The indicators being sought were liver surface irregularity, demodulation of hepatic veins, and spleen length >110 mm. Patients presenting at least one of these underwent elastography measurements with virtual touch quantification (VTQ) or supersonic shear imaging (SSI). If elastography was positive, patients were referred to hepatologist for fibrosis evaluation. Reference standard was obtained by FibroMeter VCTE or biopsy. A FibroMeter VCTE result >0.384 indicated a “necessary referral” to a hepatologist. Results Of the 1501 patients included, 504 (33.6%) were positive for at least one US indicator. All of them underwent US elastography, with 85 being positive. Of the patients, 58 (3.6%) had a consultation with a liver specialist: 21 had positive FibroMeter VCTE and nine had an indication of biopsy for suspicion of fibrosis. This screening algorithm made it possible to diagnose 1.6% of patients in our population with unknown fibrosis. Of the patients, 50% referred to the liver specialist were “necessary referrals.” Conclusion Our study suggests that three simple US indicators with no systematic elastographic measurement could be applied in day-to-day practice to look for hepatic fibrosis in an unsuspected population allowing relevant referrals to a hepatologist

Clinical Characteristics and Outcomes of 821 Older Patients With SARS-Cov-2 Infection Admitted to Acute Care Geriatric Wards

International audienceBackground: There is limited information describing the characteristics and outcomes of hospitalized older patients with confirmed coronavirus disease 2019 (COVID-19).Methods: We conducted a multicentric retrospective cohort study in 13 acute COVID-19 geriatric wards, from March 13 to April 15, 2020, in Paris area. All consecutive patients aged ≥ 70 years, with confirmed COVID-19, were enrolled.Results: Of the 821 patients included in the study, the mean (SD) age was 86 (7) years; 58% were female; 85% had ≥ 2 comorbidities; 29% lived in an institution; and the median (interquartile range) Activities of Daily Living Scale (ADL) score was 4 [2-6]. The most common symptoms at COVID-19 onset were asthenia (63%), fever (55%), dyspnea (45%), dry cough (45%) and delirium (25%). The in-hospital mortality was 31% (95% confidence interval [CI], 27 to 33). On multivariate analysis, at COVID-19 onset, the probability of in-hospital mortality was increased with male gender (odds ratio [OR], 1.85; 95% CI, 1.30 to 2.63), ADL score < 4 (OR, 1.84; 95% CI, 1.25 to 2.70), asthenia (OR, 1.59; 95% CI, 1.08 to 2.32), quick Sequential Organ Failure Assessment score ≥ 2 (OR, 2.63; 95% CI, 1.64 to 4.22) and specific COVID-19 anomalies on chest computerized tomography (OR, 2.60; 95% CI, 1.07 to 6.46).Conclusions: This study provides new information about older patients with COVID-19 who are hospitalized. A quick bedside evaluation at admission of sex, functional status, systolic arterial pressure, consciousness, respiratory rate and asthenia can identify older patients at risk of unfavorable outcomes
