Résumé : International audience
The Qinling–Dabie Belt represents the boundary between the North and South China Blocks (NCB, SCB, respectively), where ultrahigh-pressure (UHP) rocks are widespread. A structural study in eastern Qinling and zircon LA ICPMS dating of the migmatite that form the core of the Central Qinling Unit allows us to argue that continental collision occurred in Silurian, before 400 Ma. In the Late Palaeozoic, from Devonian to Permian, the northern margin of SCB experienced a continental rifting. From Late Permian to Middle Triassic, northward continental subduction of SCB is responsible for the development of a high-pressure metamorphism. The age of the UHP metamorphism remains unsettled yet. A two-time genesis, Early Palaeozoic and Early Triassic, is often preferred, but a single Palaeozoic age followed by a Triassic resetting cannot be ruled out.

Résumé : International audience
When fish larvae recruit back to a reef, chemical cues are often used to find suitable habitat or to find juvenile or adult conspecifics. We tested if the chemical information used by larvae was intentionally produced by juvenile and adult conspecifics already on the reef (communication process) or whether the cues used result from normal biochemical processes with no active involvement by conspecifics (“spying” behavior by larvae). Conspecific chemical cues attracted the majority of larvae (four out of the seven species tested); although while some species were equally attracted to cues from adults and juveniles (Chromis viridis, Apogon novemfasciatus), two exhibited greater sensitivity to adult cues (Pomacentrus pavo, Dascyllus aruanus). Our results indicate also that spying cues are those most commonly used by settling fishes (C. viridis, P. pavo, A. novemfasciatus). Only one species (D. aruanus) preferred the odour of conspecifics that had had visual contact with larvae (communication).

Résumé : International audience
The diagnosis of some infectious diseases is sometimes difficult to make and new diagnostic tools have been regularly assessed to that end. 18fluoro-deoxyglucose ((18)FDG) positron-emission tomography (PET) coupled with computed tomography (CT) is one of these new procedures. It has been evaluated for numerous infectious diseases with uneven results. A literature review allowed drawing some conclusions. First, (18)FDG-PET/CT is not currently a first-line procedure for infectious diseases. Second, it has proved useful for the evaluation of patients presenting with fever of unknown origin (FUO). Its negative predictive value is 100%: the symptoms of patients experiencing FUO with negative first-line investigations and a negative (18)FDG-PET/CT will almost always spontaneously disappear. Third, (18)FDG-PET/CT also seems to be contributive for the diagnosis of vascular prosthesis infections or osteomyelitis. Fourth, it has promising results for patients presenting with infective endocarditis, especially for secondary infectious foci, or for patients presenting with suspected infection of pacemakers or implanted defibrillator; but results are still preliminary and must be confirmed. Finally(18)FDG-PET/CT cannot be recommended yet for other infectious diseases due to lack of published data.

Résumé : International audience
A network of 26 GPS sites was implemented in Iran and Northern Oman to measure displacements in this part of the Arabia–Eurasia collision zone. We present the GPS velocity field obtained from three surveys performed in 1999 September, 2001 October and 2005 September and the deduced strain tensor. This study refines previous studies inferred from only the two first surveys. Improvements are significant in NE Iran. The present-day shortening rate across the mountain belts of NE Iran is estimated to 5 ± 1 mm yr−1 at about N11°, 2 ± 1 mm yr−1 of NS shortening across the eastern Kopet Dag and 3 ± 1 mm yr−1 of NS shortening across Binalud and Kuh-e-Sorkh. Our GPS measurements emphasize the varying character of the Kopet Dag deformation between its southeastern part with prevailing thrusting at low rates and its northwestern part with dominant strike-slip activity at increasing rates. The principal axes of the horizontal strain tensor appears very homogeneous from the Zagros to the Alborz and the Kopet-Dag (N20°) and in eastern Iran (Makran and Lut block: N30°). Only NW Iran suffers a variable strain pattern which seems to wrap the Caspian basin. The strain tensor map underlines the existence of large homogeneous tectonic provinces in terms of style and amplitude of the deformation.

Résumé : National audience
Objectives To define the different stages of spontaneous labour. To determine the indications, modalities of use and the effects of administering synthetic oxytocin. And to describe undesirable maternal and perinatal outcomes associated with the use of synthetic oxytocin. Method A systematic review was carried out by searching Medline database and websites of obstetrics learned societies until March 2016. Results The 1st stage of labor is divided in a latence phase and an active phase, which switch at 5 cm of cervical dilatation. Rate of cervical dilatation is considered as abnormal below 1 cm per 4 hour during the first part of the active phase, and blow 1 cm per 2 hours above 7 cm of dilatation. During the latent phase of the first stage of labor, i.e. before 5 cm of cervical dilatation, it is recommended that an amniotomy not be performed routinely and not to use oxytocin systematically. It is not recommended to expect the active phase of labor to start the epidural analgesia if patient requires it. If early epidural analgesia was performed, the administration of oxytocin must not be systematic. If dystocia during the active phase, an amniotomy is recommended in first-line treatment. In the absence of an improvement within an hour, oxytocin should be administrating. However, in the case of an extension of the second stage beyond 2 hours, it is recommended to administer oxytocin to correct a lack of progress of the presentation. If dynamic dystocia, it is recommended to start initial doses of oxytocin at 2 mUI/min, to respect at least 30 min intervals between increases in oxytocin doses delivered, and to increase oxytocin doses by 2 mUI/min intervals without surpassing a maximum IV flow rate of 20 mUI/min. The reported maternal adverse effects concern uterine hyper-stimulation, uterine rupture and postpartum haemorrhage, and those of neonatal adverse effects concern foetal heart rate anomalies associated with uterine hyper-stimulation, neonatal morbidity and mortality, neonatal jaundice, weak suck/poor breastfeeding latch and autism. Conclusion The widespread use of oxytocin during spontaneous labour must not be considered as simply another inoffensive prescription without any possible deleterious consequences for mother or foetus. Conditions for administering the oxytocin must therefore respect medical protocols. Indications and patient consent have to be report in the medical file. © 2016 Elsevier Masson SAS

Résumé : International audience
After noting the forecast of a La Niña episode, associated with heavy rainfall in French Guiana, we monitored the fate of wasp nests before and during the 2006 short rainy season. The population of the most abundant epiponine wasp species, Polybia bistriata, decreased dramatically during the short rainy season (60.6% of the nests disappeared) then remained low for at least 18 months. Colonies that survived moved from the shelter of large, low leaves (a situation well adapted to the previous dry season) of the most frequent substrate tree, Clusia grandiflora (Clusiaceae), to upper leaves, better ventilated and whose orientation provides good protection from the rain. Therefore, the possibility of moving the nest higher during the first rains following the dry season seems very adaptive as colonies that do not do so are eliminated during the La Niña years, whose frequency will increase with global climate change.

Résumé : International audience
Objectifs Aucun consensus n’existe concernant la prise en charge des pneumothorax spontanés de grande abondance. Les recommandations actuelles proposent soit une exsufflation à l’aiguille, soit un drainage thoracique, la plupart des patients étant hospitalisés. Nous avons voulu tester l’efficacité d’une prise en charge ambulatoire des pneumothorax par cathéters de petit calibre dit en « queue de cochon ». Méthodes De février 2007 à janvier 2011, tous les pneumothorax spontanés primaires et secondaires de grande abondance reçus à l’hôpital de Lorient ont été pris en charge par drainage via un cathéter de petit calibre associé à une valve anti-retour. Les patients rentraient immédiatement à domicile et étaient par la suite évalués tous les deux jours selon un algorithme précis. Résultats Sur 132 pneumothorax consécutifs (110 spontanés primaires, 22 secondaires), 103 ont été exclusivement traités en ambulatoire avec un retour complet à la paroi thoracique à j2 ou j4, ce qui représente un succès de l’ambulatoire à 78 %. La durée moyenne de drainage était de 3,4 jours. Sept patients ont été initialement hospitalisés, mais sont rapidement rentrés à domicile et ont été totalement guéris à j2 ou j4, ramenant le taux de succès à 83 %. L’usage d’antalgique était faible. Le taux de récidive à un an était de 26 %. En cas de succès, cette prise en charge est potentiellement économique avec un coût moyen estimé à 926 comprenant 2 consultations et une radiographie thoracique, en comparaison aux 4276 estimés si le patient était hospitalisé avec mise en place d’un drain thoracique pendant 4 jours. Conclusion La prise en charge ambulatoire des pneumothorax spontanés de grande abondance par cathéters de type « queue de cochon » associés à une valve anti-retour peut être considérée comme un traitement de première intention raisonnable. En comparaison avec d’autres études, notre protocole ne nécessite pas d’hospitalisation et est économique

Résumé : International audience
Although they are famous among Earth scientists, the Lherz peridotites are exposed within geological formations of the North Pyrenean Zone (NPZ) still lacking detailed investigations. Our study focuses on the metasediments of the Aulus basin hosting the Lherz peridotite body and associated ultramafic fragments of smaller size. The new data set comprises of structural analysis and detailed geological mapping of the massive Mesozoic marbles that form the prerift sequence typical of the NPZ and of the ultramafic-rich clastic breccia formations surrounding the peridotite bodies. The massive marbles display an evolution from hot and ductile to cold and brittle deformation, indicative of an exhumation process ending with the sedimentary reworking of both the deformed Mesozoic metasediments and the exhumed ultramafic rocks. Crystal Preferred Orientations (CPO) measured in the marbles support a deformation mechanism by dislocation creep of calcite, which is dominant between 400 8C and 600 8C; these deformation temperatures are within the range determined earlier by Clerc et al. (2015), using RSCM (Raman Spectroscopy of Carbonaceous Material) geothermometry. As a consequence, we better describe the transition from ductile to brittle deformation in the prerift marbles and clarify the origin of the syn-rift breccias. Due to continuous exhumation along detachments' faults, the brecciated metamorphic carbonates of the prerift NPZ sedimentary cover were passively uplifted towards shallower levels and progressively unroofed, while transported passively on the back of the exhumed ultramafic footwall. These results are consistent with the recent interpretations of the North Pyrenean peridotites as remnants of subcontinental mantle rocks exhumed within the pre-Pyrenean rift system. We emphasize the importance of tectonic decoupling between the Mesozoic sedimentary cover and the Palaeozoic basement, which leads to the juxtaposition of metamorphosed and deformed Mesozoic Please cite this article in press as: Lagabrielle Y, et al.

Résumé : National audience
OBJECTIVES: Medical tools to determine the imminence of unplanned out-of-hospital birth have not been validated. The main goal of this study was to analyze assessments of the imminence of these deliveries, by methods such as the Manilas score and the need to push. PATIENTS AND METHODS: All calls made to the Emergency Medical Aid Service in Guadeloupe concerning risks of unplanned delivery between January 1st and June 30th 2011 were reviewed retrospectively, and 69 of the 85 cases cared for by the hospital mobile emergency unit were included. RESULTS: Risks of unplanned out-of-hospital deliveries represented 1.9% of the calls during the study period. The Malinas score was used for dispatching in only 13% and was not used for intervention in any case. It was estimated that the need-to-push feeling was used for 58% (dispatching) and 54.5% (intervention) of patients. Its sensitivity, specificity and predictive values were higher than those of the Malinas score in dispatching and substantially higher in intervention. CONCLUSION: These results argue for the development of tools for estimating the imminence of unplanned delivery. Such tools should be applicable in extra-hospital emergency situations to ensure their use in practice.

Résumé : International audience
This observation perfectly illustrates the main epidemiological, clinical and biological peculiarities of this parasitic disease. Particularly, as it concerns a tourist who travelled across Africa for a short period of time it is possible to assess the time of exposure to infecting mosquito bites, the maturation period of time as well as the time of clinical incubation. On the other hand the value of the immunological techniques to make the diagnosis of loaiasis as well as the difficulties to treat this affection are stressed upon.

Résumé : International audience
AIM: To describe the amount of medical and paramedical involvement in a sample of Breton children with cerebral palsy as a function of the Gross Motor Function Classification System (GMFCS). MATERIALS AND METHODS: This is a transversal descriptive study. All children with cerebral palsy in Brittany were eligible. Parents who accepted to participate were asked to fill in a questionnaire regarding medical and paramedical involvement with their child. RESULTS: One hundred and thirty-three parents participated. 40.6% of the children were level I on the GMFCS, 20.3% II, 12.03% III, 13.53% IV and 13.53% were level V. Thirty-nine percent of the children took at least one medication (of which 43% were antiepileptic drugs). 33.1% of the children had received at least one injection of botulinum toxin within the year. Forty-four percent used a mobility aid. Eighty-five percent of the children had at least one orthotic device, most often a night ankle-foot orthosis. The median number of rehabilitation sessions per week was 3.85 [0.5-11.5]. The frequency and type of sessions were mostly related to the GMFCS level. CONCLUSION: This study reports high levels of medical and paramedical involvement. Studies must attempt to define optimal practice.

Résumé : La présente revue a pour but de faire état des travaux traitant de la relation entre la musique et la performance sportive à des efforts de courte et de longue durées.L’analyse de la littérature souligne clairement les bénéfices de la musique sur les performances motrices et/ou sportives. La plupart des études révèle que la musique écoutée avant, pendant ou après l’effort influence les processus psychophysiologiques de la performance et/ou la performance elle-même à des efforts de courte ou de longue durées. La littérature révèle toute la complexité de la relation musique–performance dans la mesure où cette relation implique un grand nombre de facteurs, de type interne, situationnel et contextuel, entrant en interaction complexe, affectant ainsi les sphères affective, cognitive, motivationnelle, physiologique et comportementale des individus.Si la littérature relate un nombre considérable de travaux confortant l’hypothèse selon laquelle la musique améliore la performance, la compréhension des mécanismes psychophysiologiques sous-tendant la relation musique–performance reste encore limitée. L’adoption de la perspective complexe et dynamique proposée dans ce présent travail pourrait permettre de faire la lumière sur les mécanismes sous-tendant cette relation.Bien que l’examen de la relation musique–performance réponde à un objectif essentiellement théorique, la compréhension de ses mécanismes devrait permettre de développer des stratégies pouvant améliorer la performance sportive.

Résumé : Eperua falcata (Aublet), a late-successional species in tropical rainforest and one of the most abundant tree in French Guiana, has developed an original strategy concerning N-acquisition by largely preferring nitrate, rather than ammonium (H. Schimann, S. Ponton, S. Hattenschwiler, B. Ferry, R. Lensi, A.M. Domenach, J.C. Roggy, Differing nitrogen use strategies of two tropical rainforest tree species in French Guiana: evidence from N-15 natural abundance and microbial activities, Soil Biol, Biochem. 40 (2008) 487-494). Given the preference of this species for nitrate, we hypothesized that root exudates would promote nitrate availability by (a) enhancing nitrate production by stimulating ammonium oxidation or (b) minimizing nitrate losses by inhibiting denitrification. Root exudates were collected in situ in monospecific planted plots. The phytochemical analysis of these exudates and of several of their corresponding root extracts was achieved using UHPLC/DAD/ESI-QTOF and allowed the identification of diverse secondary metabolites belonging to the flavonoid family. Our results show that (i) the distinct exudation patterns observed are related to distinct root morphologies, and this was associated with a shift in the root flavonoid content, (ii) a root extract representative of the diverse compounds detected in roots showed a significant and selective metabolic inhibition of isolated denitrifiers in vitro, and (iii) in soil plots the abundance of nirK-type denitrifiers was negatively affected in rhizosphere soil compared to bulk. Altogether this led us to formulate hypothesis concerning the ecological role of the identified compounds in relation to N-acquisition strategy of this species. (C) 2013 Elsevier Masson SAS.
