The objective of this study was to evaluate the performance of physicians in predicting the need for RRT at ICU admission and at acute kidney injury (AKI) diagnosis. Methods Prospective, multicenter study including all adult patients hospitalized in 16 ICUs in October 2020. Physician prediction was estimated at ICU admission and at...

Delivery decision in pregnant women rescued by ECMO for severe ARDS: a retrospective multicenter cohort study

Sarah Aissi James, Christophe Guervilly, Mathieu Lesouhaitier, Alexandre Coppens, Clément Haddadi, Guillaume Lebreton, Jacky Nizard, Nicolas Brechot, Benjamin Assouline, Ouriel Saura, David Levy, Lucie Lefèvre, Pétra Barhoum, Juliette Chommeloux, Guillaume Hékimian, Charles-Edouard Luyt, Antoine Kimmoun, Alain Combes & Matthieu Schmidt
Abstract Background Although rarely addressed in the literature, a key question in the care of critically pregnant women with severe acute respiratory distress syndrome (ARDS), especially at the time of extracorporeal membrane oxygenation (ECMO) decision, is whether delivery might substantially improve the mother’s and child’s conditions. This multicenter, retrospective cohort aims to report maternal and fetal short- and long-term outcomes of pregnant women with ECMO-rescued severe ARDS according to the timing of the delivery decision...

Educational interventions to integrate surgical staff within medical units during the COVID-19 pandemic: EDUCOVID survey

Raffaele Brustia, Giuliana Amaddeo, Rami Rhaiem, Eric Levesque, Antoine Monsel, Vanessa Baaroun, Mylène Dimmock, Marc-Antoine Rousseau, Oriane Wagner-Ballon, Francoise Botterel, Pascal Andujar & Daniele Sommacale
The SARS-CoV-2 (COVID-19) pandemic required a rapid surge of healthcare capacity to face a growing number of critically ill patients. For this reason, a support reserve of physicians, including surgeons, were required to be reassigned to offer support. To realize a survey on the educational programs deployed (face-to-face or e-learning focusing on infective area, basic gestures, COVID clinical management and intensive care medicine), and their impact on behavior change (Kirkpatrick 3) of the target population...

Interplay of greening and ENSO on biosphere–atmosphere processes in Australia

Shijing Liang, Alan D. Ziegler, Laurent Z. X. Li, Jie Wu, Dashan Wang & Zhenzhong Zeng
Abstract Terrestrial ecosystems are fully coupled with the climate. The planet has been greening owing to the increased vegetation growth in response to the changing atmosphere, which in turn has feedback on the climate. Greening has slowed down the rise in global land-surface air temperature mainly through a coincident increase of evapotranspiration and precipitation in wet regions. In dry regions, greening intensifies the decrease in soil moisture induced by greening-enhanced transpiration. Uncertain, however, is how...

Emergence of psychiatric adverse events during antipsychotic treatment in AP-naïve children and adolescents

Marie-Line Menard, Philippe Auby, Coralie Cruzel, David Cohen, Olivier Bonnot, Florence Askenazy & Susanne Thümmler
Abstract Background Over the last decades, antipsychotic prescriptions in children have increased worldwide. However, adverse events are frequently observed, with some such as psychiatric adverse events remaining poorly documented. Method The French ETAPE study is a 12-month naturalistic prospective multisite study that included 190 antipsychotic-naïve pediatric patients (mean age = 12 ± 3 years), treated by antipsychotic for psychotic or non-psychotic symptoms. From the ETAPE database, we performed additional analyses focusing on psychiatric adverse events....

Retrospective analysis of SARS-CoV-2 omicron invasion over delta in French regions in 2021–22: a status-based multi-variant model

Thomas Haschka, Elisabeta Vergu, Benjamin Roche, Chiara Poletto & Lulla Opatowski
Abstract Background SARS-CoV-2 is a rapidly spreading disease affecting human life and the economy on a global scale. The disease has caused so far more then 5.5 million deaths. The omicron outbreak that emerged in Botswana in the south of Africa spread around the globe at further increased rates, and caused unprecedented SARS-CoV-2 infection incidences in several countries. At the start of December 2021 the first omicron cases were reported in France. Methods In this...

Application of machine learning to predict transport modes from GPS, accelerometer, and heart rate data

Santosh Giri, Ruben Brondeel, Tarik El Aarbaoui & Basile Chaix
Abstract Background There has been an increased focus on active transport, but the measurement of active transport is still difficult and error-prone. Sensor data have been used to predict active transport. While heart rate data have very rarely been considered before, this study used random forests (RF) to predict transport modes using Global Positioning System (GPS), accelerometer, and heart rate data and paid attention to methodological issues related to the prediction strategy and post-processing. Methods...

A CO2-free cloud mask from IASI radiances for climate applications (from IASI/Metop-A)

simon whitburn
The IASI Cloud Detection product (IASI CLD) is a cloud mask available at the IASI pixel level (L2) that was developed for climate applications purposes. The algorithm is detailed in Whitburn et al. (2022, Atmospheric Measurement Techniques). It combines (1) a high sensitivity to cloud detection, (2) a very good consistency over time and between the three IASI instruments and (3) simplicity in its parametrization. The method is based on the use of a supervised...

Multiple retrograde tracing methods compatible with 3DISCO clearing

Shuai Han, Dongdong Li, Yuhui Kou, Zhongguo Fu & Xiaofeng Yin
Exploring the spatial relationship of various neuron pools in the spinal cord is crucial and difficult due to its complexity. The single-labelling tracing and sectioning were employed in previous studies exploring the distribution of spinal motor neuron pools, which could only delineate one single motor neuron pool in one specimen and could not achieve intact-tissue observation. Here, with combination of neuroanatomy tracing techniques and the optical clearing technique, we developed a multiple retrograde tracing method...

Data from: Genetic architecture of inbreeding depression and the maintenance of gametophytic self-incompatibility

Camille Elsa Gervais, Diala Abu Awad, Denis Roze, Vincent Castric, Sylvain Billiard & Camille Gervais
Gametophytic self-incompatibility is a widespread genetic system, which enables hermaphroditic plants to avoid self-fertilization and mating with close relatives. Inbreeding depression is thought to be the major force maintaining self-incompatibility; however, inbreeding depression is a dynamical variable that depends in particular on the mating system. In this paper we use multilocus, individual based simulations to examine the co-evolution of self-incompatibility and inbreeding depression within finite populations. We focus on the conditions for the maintenance of...

Data from: Rapid morphological changes, admixture and invasive success in populations of Ring-necked parakeets (Psittacula krameri) established in Europe

Ariane Le Gros, Sarah Samadi, Dario Zuccon, Raphaël Cornette, Michael P. Braun, Juan Carlos Senar & Philippe Clergeau
The Ring-necked parakeet (Psittacula krameri), native of Asia and Africa, is a very successful invasive species in Europe: it has been present there for over 50 years. A recent study showed that European invasive populations occupy a colder climatic niche than in their native range but the establishment of this tropical species in temperate regions remains unexplained. Two main hypotheses may explain the success of Ring-necked parakeet in Europe: admixture between individuals from different origins...

Data from: The complex phylogeography of the Indo-Malayan Alophoixus bulbuls with the description of a putative new ring species complex

Jérôme Fuchs, Per G. P. Ericson, Céline Bonillo, Arnaud Couloux & Eric Pasquet
The Indo-Malayan bioregion has provided some of the most spectacular discoveries of new vertebrate species (e.g. saola, khanyou, bare-faced bulbul) over the last 25 years. Yet, very little is known about the processes that led to the current biodiversity in this region. We reconstructed the phylogeographic history of a group of closely related passerines, the Alophoixus bulbuls. These birds are continuously distributed in Indo-Malaya around the Thailand lowlands such that their distribution resembles a ring....

Data from: Ecosystem productivity is associated to bacterial phylogenetic distance in surface marine waters

Pierre E. Galand, Ian Salter & Dimitri Kalenitchenko
Understanding the link between community diversity and ecosystem function is a fundamental aspect of ecology. Systematic losses in biodiversity are widely acknowledged but the impact this may exert on ecosystem functioning remains ambiguous. There is growing evidence of a positive relationship between species richness and ecosystem productivity for terrestrial macroorganisms, but similar links for marine microorganisms, which help drive global climate, are unclear. Community manipulation experiments show both positive and negative relationships for microbes. These...

Data from: Entangled fates of holobiont genomes during invasion: nested bacterial and host diversities in Caulerpa taxifolia

Sophie Arnaud-Haond, Tania Aires, Rui Candeias, Sara J. L. Teixeira, Carlos M. Duarte, Myriam Valero & Ester A. Serrão
Successful prevention and mitigation of biological invasions requires retracing the initial steps of introduction, as well as understanding key elements enhancing the adaptability of invasive species. We studied the genetic diversity of the green alga Caulerpa taxifolia and its associated bacterial communities in several areas around the world. The striking congruence of α and ß diversity of the algal genome and endophytic communities reveals a tight association, supporting the holobiont concept as best describing the...

Data from: Climate warming: a loss of variation in populations can accompany reproductive shifts

Manuel Massot, Stephane Legendre, Pierre Fédérici & Jean Clobert
The most documented response of organisms to climate warming is a change in the average timing of seasonal activities (phenology). Although we know that these average changes can differ among species and populations, we do not know whether climate warming impacts within-population variation in phenology. Using data from five study sites collected during a 13-year survey, we found that the increase in spring temperatures is associated with a reproductive advance of 10 days in natural...

Data from: The third dimension: a novel set-up for filming coelacanths in their natural environment

Thierry Décamps, Anthony Herrel, Laurent Ballesta, Florian Holon, Thibault Rauby, Yannick Gentil, Cédric Gentil, Hugo Dutel, Regis Debruyne, Jean-Benoit Charrassin, Guillaume Eveillard, Gaël Clément & Marc Herbin
Here, we describe a novel design to obtain three-dimensional data on the movements of aquatic organisms at depths of up to 140 m. The set-up consists of two synchronized high-speed cameras fixed to two articulated arms. The set-up was successfully used to film and quantify the locomotion of coelacanths Latimeria chalumnae living at a depth of about 120 m in Sodwana Bay, South Africa. As an example, the detailed motion of the dorsal fin is...

Data from: Geographically distinct patterns of reproductive isolation and hybridisation in two sympatric species of the Jaera albifrons complex (marine isopods)

Ambre Ribardière, Claire Daguin-Thiébaut, Céline Houbin, Jérôme Coudret, Caroline Broudin, Olivier Timsit & Thomas Broquet
Sympatric species that in some populations hybridize and in other populations remain reproductively isolated open interesting research possibilities for the study of hybridization and speciation. Here we test for such a situation in two littoral isopods (Jaera albifrons and J. praehirsuta) that occur in mixed populations and where past morphological descriptions suggested that the two species are generally reproductively isolated except in rare populations where hybridization may be happening. Using field surveys and microsatellite genetic...

Data from: Drivers of vegetative dormancy across herbaceous perennial plant species

Richard P. Shefferson, Tiiu Kull, Michael J. Hutchings, Marc-André Selosse, Hans Jacquemyn, Kimberly M. Kellett, Eric S. Menges, Richard B. Primack, Juha Tuomi, Kirsi Alahuhta, Sonja Hurskainen, Helen M. Alexander, Derek S. Anderson, Rein Brys, Emilia Brzosko, Slavomir Dostálik, Katharine Gregg, Zdeněk Ipser, Anne Jäkäläniemi, Jana Jersáková, W. Dean Kettle, Melissa K. McCormick, Ana Mendoza, Michael T. Miller, Asbjørn Moen … & Dennis F. Whigham
Vegetative dormancy, that is the temporary absence of aboveground growth for ≥ 1 year, is paradoxical, because plants cannot photosynthesise or flower during dormant periods. We test ecological and evolutionary hypotheses for its widespread persistence. We show that dormancy has evolved numerous times. Most species displaying dormancy exhibit life‐history costs of sprouting, and of dormancy. Short‐lived and mycoheterotrophic species have higher proportions of dormant plants than long‐lived species and species with other nutritional modes. Foliage...

Data from: Divergent in shape and convergent in function: adaptive evolution of the mandible in Sub-Antarctic mice

Sabrina Renaud, Ronan Ledevin, Benoît Pisanu, Jean-Louis Chapuis, Petra Quillfeldt & Emilie A. Hardouin
Convergent evolution in similar environments constitutes strong evidence of adaptive evolution. Transported with people around the world, house mice colonized even remote areas, such as Sub-Antarctic islands. There, they returned to a feral way of life, shifting towards a diet enriched in terrestrial macroinvertebrates. Here, we test the hypothesis that this triggered convergent evolution of the mandible, a morphological character involved in food consumption. Mandible shape from four Sub-Antarctic islands was compared to phylogeny, tracing...
