Objectif Analyser les caractéristiques virologiques et les complications des syndromes grippaux chez les diabétiques en période hivernale. Patients et Méthodes Étude conduite dans 6 hôpitaux (Montpellier, Lyon, Cochin, Bichat, Limoges, Rennes) au cours de 3 saisons grippales (2012-2013, 2013-2014 et 2014-2015), sur 1 451 adultes hospitalisés avec syndrome grippal récent (début ≤ 7 jours), associant un signe respiratoire (toux, dys-pnée) et un signe systémique (fièvre, céphalées, malaise, myalgies). Les virus respiratoires étaient recherchés par RT-PCR sur prélèvement naso-pharyngé ou LBA (Centre National de Référence, Lyon). La vaccination anti-grippale, la présence d'un diabète, les comorbidités, les complications en cours d'hospitalisation (insuffisance rénale, cardiaque, respiratoire, pneumonie, décès) et la durée moyenne de séjour (DMS) étaient enregistrées. Les facteurs de risque de complications ont été étudiés par régression logistique multivariée ajustée sur âge, sexe, infection grippale, vaccination, diabète et antécédents de pathologies rénale, cardiaque ou respiratoire. Résultats Les hospitalisations ont eu lieu dans des services de maladies respiratoires, médecine interne, MIT et réanimation. Un diabète était présent chez 368 sujets (non traités : 15 %, ADO : 41 %, insuline : 27 %, mixte : 17 %). Les diabétiques étaient plus âgés (71 ± 15 vs 65 ± 20 ans, P < 0,001) et présentaient plus souvent un antécédent de pathologie rénale (18 % vs 8 %, P < 0,00001) ou cardiaque (19 % vs 11 %, P < 0,001). Leur couverture vaccinale était meilleure (60 % vs 46 %). Les données virologiques étaient comparables : grippe 38,9 % (76,1 % type A) vs 39,2 % ; (74,1 % type A) ; autres virus respiratoires : 17,0 % vs 19,9 %. La DMS était un peu plus élevée chez les diabétiques (9,1 ± 9 vs 8,9 ± 11, P = 0,015), avec une tendance à un risque de décès plus élevé (6,25 % vs 3,97 %, P 0,07). En analyse multivariée, le diabète était un facteur de risque de complications à type d'insuffisance rénale (OR : 1,66, IC 95 % : 1,10-2,52) mais pas d'insuffisance cardiaque, respiratoire ou de décès. Les complications n'étaient pas modi-fiées par les résultats virologiques. Conclusions Le diabète est un facteur de risque de complications rénales chez les patients hospitalisés avec syndrome grippal

Résumé : International audience
In 2008 we published the first set of guidelines for standardizing research in autophagy. Since then, research on this topic has continued to accelerate, and many new scientists have entered the field. Our knowledge base and relevant new technologies have also been expanding. Accordingly, it is important to update these guidelines for monitoring autophagy in different organisms. Various reviews have described the range of assays that have been used for this purpose. Nevertheless, there continues to be confusion regarding acceptable methods to measure autophagy, especially in multicellular eukaryotes. A key point that needs to be emphasized is that there is a difference between measurements that monitor the numbers or volume of autophagic elements (e.g., autophagosomes or autolysosomes) at any stage of the autophagic process vs. those that measure flux through the autophagy pathway (i.e., the complete process); thus, a block in macroautophagy that results in autophagosome accumulation needs to be differentiated from stimuli that result in increased autophagic activity, defined as increased autophagy induction coupled with increased delivery to, and degradation within, lysosomes (in most higher eukaryotes and some protists such as Dictyostelium) or the vacuole (in plants and fungi). In other words, it is especially important that investigators new to the field understand that the appearance of more autophagosomes does not necessarily equate with more autophagy. In fact, in many cases, autophagosomes accumulate because of a block in trafficking to lysosomes without a concomitant change in autophagosome biogenesis, whereas an increase in autolysosomes may reflect a reduction in degradative activity. Here, we present a set of guidelines for the selection and interpretation of methods for use by investigators who aim to examine macroautophagy and related processes, as well as for reviewers who need to provide realistic and reasonable critiques of papers that are focused on these processes. These guidelines are not meant to be a formulaic set of rules, because the appropriate assays depend in part on the question being asked and the system being used. In addition, we emphasize that no individual assay is guaranteed to be the most appropriate one in every situation, and we strongly recommend the use of multiple assays to monitor autophagy. In these guidelines, we consider these various methods of assessing autophagy and what information can, or cannot, be obtained from them. Finally, by discussing the merits and limits of particular autophagy assays, we hope to encourage technical innovation in the field.

The respiratory manifestations of eosinophilic granulomatosis with polyangiitis (EGPA) have not been studied in detail. In this retrospective multicentre study, EGPA was defined by asthma, eosinophilia and at least one new onset extra-bronchopulmonary organ manifestation of disease. The study population included 157 patients (mean±SD age 49.4±14.1 years), with a mean±SD blood eosinophil count of 7.4±6.4×109 L-1 at diagnosis. There was a mean±SD of 11.8±18.2 years from the onset of asthma to the diagnosis of EGPA, of 1.4±8.4 years from the first onset of peripheral eosinophilia to the diagnosis of EGPA, and of 7.4±6.4 years from EGPA diagnosis to the final visit. Despite inhaled and oral corticosteroid treatment, the severity of asthma increased 3-6 months before the onset of the systemic manifestations. Asthma was severe in 57%, 48%, and 56% of patients at diagnosis, at 3 years, and at the final visit, respectively. Persistent airflow obstruction was present in 38%, 30%, and 46% at diagnosis, at 3 years, and at the final visit, respectively. In EGPA, asthma is severe, antedates systemic manifestations by a mean of 12 years, and progresses to long-term persistent airflow obstruction despite corticosteroids in a large proportion of patients, which affects long-term management and morbidity.

Résumé : During the Fanindien 2006 cruise of R/V 'Beautemps-Beaupre', high resolution multibeam bathymetry, sub-bottom profiling and sediment coring was carried out along the East African margin, offshore Tanzania and Mozambique (Indian Ocean). The newly acquired data reveal the presence of a giant deep-sea valley (the Tanzania channel) that is more than 10 km wide at 4000 m water depth, along the continental rise. The valley remains similar to 70 m deep and 7 km wide at 800 km from the Tanzania coast. Morphological comparison with worldwide submarine channels show that the Tanzania channel is one of the largest known submarine valleys. This discovery brings new light on development of submarine valleys that drain sediments originated from the East African Rift System (EARS) highlands (i.e. the Tanzania channel and its neighbor Zambezi channel located similar to 1000 km southward). Both of the systems have a morphology markedly different to the classical sinuous, V-shaped channels located at similar latitudes (e.g. the Zaire or Amazon channels). Their submarine drainage system consists of a downslope converging tributary canyons joining a central trunk channel in the continental rise. The presence of such giant deep-sea drainage systems is probably linked to a strong structural control on the sediment pathway, associated to a massive sediment transfer towards the Indian Ocean in relation with the tectonic activity of the East African Rift System (i.e. the uplift periods trough mid-Miocene and Plio-Pleistocene times) and its interplay with the East African equatorial climate changes.

Résumé : Mafic microgranular enclaves produced by co-mingling between minette and syenite magmas are found in the Piquiri Syenite, southern Brazil. These enclaves were crystallized under upper mantle conditions. K-clinopyroxene and pyrope are among the early-crystallized phases, suggesting an initial pressure around 5GPa. The mineralogy of minettes comprises phenocrysts of magnesium biotite and diopside, occasionally apatite, in a groundmass formed by these minerals plus alkali feldspar. Two types of apatites are observed: (i) euhedral grains, as inclusions or groundmass constituents, and (ii) aciculate crystals formed during undercooling of mafic magma. Substitutional schemes suggested for these apatites are Si ⇆ P in the tetrahedral site, and Sr and LREE replacing Ca. La, Ce, Nd, and Sr concentrations reveal that these elements are extremely enriched in apatite. Partition coefficients between early-crystallized apatites and estimated melt compositions are DLa (11.8 - 30.6), DCe (16.1-33), DNd (12-31) and DSr (5.1-8.2). Apatite concentrates the LREE up to 200 times compared to clinopyroxene, even higher values were determined for ap/mica partitioning. The ap/cpx and ap/mica partition coefficients for undercooled minerals are close to the values determined for the near-liquidus phases, which indicates constant behavior of LREE and Sr between apatite-clinopyroxene-mica parageneses and minette liquids. Furthermore, these partitioning data preclude any chemical diffusion of these elements between minette and syenite magmas during co-mingling.

Résumé : International audience
Telomerase reverse transcriptase (TERT) or telomerase RNA (TERC) gene mutation is a major monogenic cause of pulmonary fibrosis. Sequencing of TERT/TERC genes is proposed to patients with familial pulmonary fibrosis. Little is known about the possible predictors of this mutation and its impact on prognosis. We retrospectively analysed all the genetic diagnoses made between 2007-2014 in patients with pulmonary fibrosis. We evaluated the prevalence of TERT/TERC disease-Associated variant (DAV), factors associated with a DAV, and the impact of the DAV on survival. 237 patients with pulmonary fibrosis (153 with familial pulmonary fibrosis, 84 with telomere syndrome features without familial pulmonary fibrosis) were tested for TERT/TERC DAV. DAV was diagnosed in 40 patients (16.8%), including five with non-idiopathic interstitial pneumonia. Prevalence of TERT/TERC DAV did not significantly differ between patients with familial pulmonary fibrosis or with only telomere syndrome features (18.2% versus 16.4%). Young age, red blood cell macrocytosis, and low platelet count were associated with the presence of DAV; the probability of DAV was increased for patients 40-60 years. Transplant-free survival was lower with than without TERT/TERC DAV (4.2 versus 7.2 years; p=0.046). TERT/TERC DAV were associated with specific clinical and biological features and reduced transplantfree survival. ©ERS 2016.

Résumé : International audience
AIM: To describe the main characteristics and the treatment of cryptococcosis in patients with sarcoidosis. DESIGN: Multicenter study including all patients notified at the French National Reference Center for Invasive Mycoses and Antifungals. METHODS: Retrospective chart review. Each case was compared with two controls without opportunistic infections. RESULTS: Eighteen cases of cryptococcosis complicating sarcoidosis were analyzed (13 men and 5 women). With 2749 cases of cryptococcosis registered in France during the inclusion period of this study, sarcoidosis accounted for 0.6% of all the cryptococcosis patients and for 2.9% of the cryptococcosis HIV-seronegative patients. Cryptococcosis and sarcoidosis were diagnosed concomitantly in four cases; while sarcoidosis was previously known in 14/18 patients, including 12 patients (67%) treated with steroids. The median rate of CD4 T cells was 145 per mm(3) (range: 55-1300) and not related to steroid treatment. Thirteen patients had cryptococcal meningitis (72%), three osteoarticular (17%) and four disseminated infections (22%). Sixteen patients (89%) presented a complete response to antifungal therapy. After a mean follow-up of 6 years, no death was attributable to cryptococcosis. Extra-thoracic sarcoidosis and steroids were independent risk factors of cryptococcosis in a logistic regression model adjusted with the sex of the patients. CONCLUSIONS: Cryptococcosis is a significant opportunistic infection during extra-thoracic sarcoidosis, which occurs in one-third of the cases in patients without any treatment; it is not associated to severe CD4 lymphocytopenia and has a good prognosis.

Résumé : International audience
Microbathymetry data, in situ observations, and sampling along the 13°20′N and 13°20′N oceanic core complexes (OCCs) reveal mechanisms of detachment fault denudation at the seafloor, links between tectonic extension and mass wasting, and expose the nature of corrugations, ubiquitous at OCCs. In the initial stages of detachment faulting and high-angle fault, scarps show extensive mass wasting that reduces their slope. Flexural rotation further lowers scarp slope, hinders mass wasting, resulting in morphologically complex chaotic terrain between the breakaway and the denuded corrugated surface. Extension and drag along the fault plane uplifts a wedge of hangingwall material (apron). The detachment surface emerges along a continuous moat that sheds rocks and covers it with unconsolidated rubble, while local slumping emplaces rubble ridges overlying corrugations. The detachment fault zone is a set of anostomosed slip planes, elongated in the along-extension direction. Slip planes bind fault rock bodies defining the corrugations observed in microbathymetry and sonar. Fault planes with extension-parallel stria are exposed along corrugation flanks, where the rubble cover is shed. Detachment fault rocks are primarily basalt fault breccia at 13°20′N OCC, and gabbro and peridotite at 13°30′N, demonstrating that brittle strain localization in shallow lithosphere form corrugations, regardless of lithologies in the detachment zone. Finally, faulting and volcanism dismember the 13°30′N OCC, with widespread present and past hydrothermal activity (Semenov fields), while the Irinovskoe hydrothermal field at the 13°20′N core complex suggests a magmatic source within the footwall. These results confirm the ubiquitous relationship between hydrothermal activity and oceanic detachment formation and evolution.

Résumé : International audience
Pituitary adenomas are currently classified by histological, immunocytochemical and numerous ultrastructural characteristics lacking unequivocal prognostic correlations. We investigated the prognostic value of a new clinicopathological classification with grades based on invasion and proliferation. This retrospective multicentric case-control study comprised 410 patients who had surgery for a pituitary tumour with long-term follow-up. Using pituitary magnetic resonance imaging for diagnosis of cavernous or sphenoid sinus invasion, immunocytochemistry, markers of the cell cycle (Ki-67, mitoses) and p53, tumours were classified according to size (micro, macro and giant), type (PRL, GH, FSH/LH, ACTH and TSH) and grade (grade 1a: non-invasive, 1b: non-invasive and proliferative, 2a: invasive, 2b: invasive and proliferative, and 3: metastatic). The association between patient status at 8-year follow-up and age, sex, and classification was evaluated by two multivariate analyses assessing disease- or recurrence/progression-free status. At 8 years after surgery, 195 patients were disease-free (controls) and 215 patients were not (cases). In 125 of the cases the tumours had recurred or progressed. Analyses of disease-free and recurrence/progression-free status revealed the significant prognostic value (p < 0.001; p < 0.05) of age, tumour type, and grade across all tumour types and for each tumour type. Invasive and proliferative tumours (grade 2b) had a poor prognosis with an increased probability of tumour persistence or progression of 25- or 12-fold, respectively, as compared to non-invasive tumours (grade 1a). This new, easy to use clinicopathological classification of pituitary endocrine tumours has demonstrated its prognostic worth by strongly predicting the probability of post-operative complete remission or tumour progression and so could help clinicians choose the best post-operative therapy.
