Extrait de : "Cartographies et topologies identitaires" : journée d'étude, le 1er mars 2018. Université des Antilles
Description : Pour faire suite à la journée d'étude autour de « cartographie et topologie identitaire », Géraldine CHOUARD, Professeure de culture américaine, René-David NELZIN dit David Né, artiste plasticien, des étudiants en hygiène, sécurité et environnement de l'UA et Hervé BEUZE artiste plasticien, présentent des oeuvres qui illustrent bien le thème de ladite journée. Géraldine CHOUARD présente le livre intitulé « L'Amérique des images ». Cet ouvrage est une compilation de recherche scientifique sur l'identité américaine à travers des images, tenant compte des fonctions sociales de celles-ci. David Né pour sa part, expose des réalisations artistiques qui selon lui ont des aspects multidimensionnels en ce sens qu'ils mettent en valeur une cartographie basée sur l'identité personnelle et sur la spiritualité. Les étudiants présentent une peinture illustrant la carte d'une ville. Et enfin Hervé BEUZE commente une de ses oeuvres. Il s'agit d'une carte de la Martinique qui traduit le mouvement de grève de l'année 2009.

Résumé : Data assembly and processing centers are essential elements of the operational oceanography infrastructure. They provide data and products needed by modeling and data assimilation systems; they also provide products directly usable for applications. This paper discusses the role and functions of the data centers for operational oceanography. It describes some of the main data assembly centers (Argo and in situ data, altimetry, sea surface temperature) developed during the Global Ocean Data Assimilation Experiment. An overview of other data centers (wind and fluxes, ocean color, sea ice) is also given. Much progress has been achieved over the past 10 years to validate, intercalibrate, and merge altimeter data from multiple satellites. Accuracy and timeliness of products have been improved, and new products have been developed. The same is true for sea surface temperature data through the Global High-Resolution Sea Surface Temperature Pilot Project. A breakthrough in processing, quality control, and assembly for in situ data has also been achieved through the development of the real-time and delayed-mode Argo data system. In situ and remote-sensing data are now systematically and jointly used to calibrate, validate, and monitor over the long term the quality and consistency of the global ocean observing system. Main results are illustrated. There is also a review of the development and use of products that merge in situ and remote-sensing data. Future issues and main prospects are discussed in the conclusion.

Résumé : International audience
Background Chlordecone is a persistent organochlorine insecticide with well-defined estrogenic properties. It was intensively used in the French West Indies until 1993 to control the banana root borer. Because of the long-term contamination of soils and water, the population is currently exposed to chlordecone through food consumption. Chlordecone has been found in the blood of pregnant women and in cord blood. It has been shown to be an endocrine-disrupting chemical and exposure during pregnancy may affect fetal growth. Objectives The objective of our study was to examine the association between prenatal exposure to chlordecone and fetal growth based on the TIMOUN birth cohort conducted in Guadeloupe, with a focus on the potential modification of this relationship by maternal body mass index (BMI) and gestational weight gain (GWG). Methods Chlordecone was determined in cord plasma at birth in 593 babies. Birth weight was the indicator of fetal growth. Maternal pre-pregnancy BMI and GWG were determined. Adherence to GWG recommendations of the US Institute of Medicine based on maternal pre-pregnancy BMI was assessed. Birth weight was analyzed relative to cord blood chlordecone levels using linear and non-linear regression models. Results Overall chlordecone in cord blood was not associated with birth weight, but we found an interaction between chlordecone exposure with GWG and adherence to GWG recommendations. After stratification by GWG, we found a significant U-shaped association between birth weight and chlordecone exposure, within the upper quartiles of GWG or excessive GWG. Conclusion Chlordecone exposure may affect fetal growth, particularly when excessive GWG is present. © 2016 Elsevier Inc.

Résumé : International audience
Seabirds concentrate nutrients from large marine areas on their nesting islands playing an important ecological role in nutrient transfer between marine and terrestrial ecosystems. Here we investigate the role of guano on corals reefs across scales by analyzing the stable nitrogen isotopic (delta N-15) values of the scleractinian coral Pocillopora damicornis on fringing reefs around two Pacific remote islets with large seabird colonies. Marine stations closest to the seabird colonies had higher nitrate + nitrite concentrations compared to more distant stations. Coral and zooxanthellae delta N-15 values were also higher at these sites, suggesting that guano-derived nitrogen is assimilated into corals and contributes to their nitrogen requirements. The spatial extent of guano influence was however restricted to a local scale. Our results demonstrate that seabird-derived nutrients not only spread across the terrestrial ecosystem, but also affect components of the adjacent marine ecosystem. Further studies are now needed to assess if this nutrient input has a positive or negative effect for corals. Such studies on remote islets also open fresh perspectives to understand how nutrients affect coral reefs isolated from other anthropogenic stressors.

Résumé : International audience
Antisynthetase syndrome is an inflammatory myopathy frequently associated with pulmonary manifestations, especially interstitial lung diseases, and uncommonly pulmonary hypertension. In the context of a suggestive clinical and radiological picture, positive anti-RNA synthetase antibodies confirm the diagnosis. Anti-Jo1, anti-PL7, and anti-PL12 antibodies are the more commonly encountered. The presence of a number of extra-thoracic manifestations in association with pulmonary disease may suggest the diagnosis. These include: myalgia or muscular deficit, Raynaud's phenomenon, polyarthritis, fever, mechanics hands. Serum creatine kinase levels are usually increased. Electromyogram, muscular magnetic resonance imaging or muscle pathology are not mandatory to make the diagnosis. There is a high variability in symptoms and severity, between patients but also during the course of the disease in the same patient. The presence of an interstitial lung disease is a major prognostic factor and an indication for more intensive treatment, principally with systemic corticosteroids with or without immunosuppressive drugs. Improving respiratory physicians’ knowledge of this disease, which is often revealed by its pulmonary manifestations, should help diagnosis, therapeutic management, and possibly prognosis.
Le syndrome des antisynthétases correspond à une myopathie inflammatoire fréquemment associée à une atteinte pulmonaire, surtout parenchymateuse (pneumopathie infiltrante diffuse) et plus rarement vasculaire (hypertension pulmonaire). Devant un tableau clinique et radiologique évocateur, la présence d’anticorps anti-ARNt synthétases signe le diagnostic. Les plus fréquents de ces auto-anticorps sont les anti-Jo1, les anti-PL7 et les anti-PL12. De nombreuses manifestations cliniques extrathoraciques associées à l’atteinte pulmonaire peuvent orienter le diagnostic : myalgies ou déficit musculaire, phénomène de Raynaud, polyarthrite, fièvre et « mains de mécaniciens ». Une augmentation des créatine-phospho-kinases est quasi constante. Le recours à l’électromyogramme, à l’imagerie musculaire par résonance magnétique ou à l’histologie n’est pas systématique. Néanmoins, il existe une grande variabilité des symptômes et de leur sévérité d’un patient à l’autre ou au long de l’évolution de la maladie. L’atteinte pulmonaire est un facteur pronostic majeur et incite à traiter de manière intensive les patients, principalement par corticothérapie systémique, voire d’emblée par association corticoïdes et immunosuppresseurs. Mieux connaître cette pathologie qui est souvent de révélation pneumologique permettrait d’améliorer le diagnostic et la prise en charge thérapeutique, voire même le pronostic.

Résumé : International audience
BACKGROUND: Mutations in the telomerase complex (TERT and TR) are associated with pulmonary fibrosis and frequent hematologic manifestations. The aim of this study was to characterize the prognosis of lung transplantation in patients with TERT or TR mutations. METHODS: Patients with documented TERT or TR mutations who received a lung transplant between 2007 and 2013 in France were identified via an exhaustive search of the lung transplantation network, one expert genetic laboratory, and the clinical research network on rare pulmonary diseases. RESULTS: There were 9 patients (7 men) with TERT (n = 6) or TR (n = 3) mutations who received a single (n = 8) or a double (n = 1) lung transplant for pulmonary fibrosis. Median age was 50 years (range, 35-61 years) at diagnosis and 52 years (range, 37-62 years) at the time of lung transplantation. Thrombocytopenia was present in 7 patients before lung transplantation. After lung transplantation, 6 patients developed myelodysplasia and/or bone marrow failure, directly contributing to death in 4 cases. Anemia was observed in 9 patients, and neutropenia was observed in 3 patients. The median survival after lung transplantation was 214 days (range, 59-1,709 days). CONCLUSIONS: Patients with mutations of the telomerase complex are at high risk of severe hematologic complications after lung transplantation, in particular, bone marrow failure. Specific recommendations should be developed for appropriate guidance regarding hematologic risk assessment before transplantation and management of the post-transplantation immunosuppressive regimen.
