Description : L'île de Trinidad, créolophone depuis du 18ème siècle et lieu d'apparition de la première grammaire du créole français antillais, a commencé à perdre sa place dans la créolophonie au début du 20ème siècle. Jusqu'au milieu du 19ème siècle pourtant, le créole français était la langue maternelle de la grande majorité des Trinidadiens et était aussi devenu la lingua franca d'une population de plus en plus multilingue. Depuis la publication de John Jacob Thomas (1869), la représentation orthographique de la langue créole a été - et est toujours - soumise à la connaissance du français et de l'étymologie française, aux interférences de la phonologie anglaise et créole anglaise (à celles de l'orthographe de l'anglais) et aux préférences individuelles. En 1990, près de deux décennies après l'introduction de la norme GEREC-1 de Bernabé, Carrington (un Trinidadien travaillant sur le st-lucien) et ses collègues de l'Université des West Indes, utilisent le système d'orthographe GEREC pour un cours basé sur le st-lucien, en utilisant des matériaux conçus par Carrington et Valdman et enseignés par des Martiniquais venus lors d'un échange avec l'UAG. Les étudiants de ce cours apprennent le GEREC-1 (le GEREC-2 n'est pas encore pratiqué) et l'utilisent dans leurs publications, présentations et dans les médias sociaux. Cependant, ces étudiants représentent bien moins de 1% de la population du pays. La connaissance de ce système graphique n'a donc pas pénétré la conscience de la grande majorité de la société trinidadienne, de sorte que les chercheurs qui ne sont pas linguistes, de même que les praticiens de la culture, les journalistes et la société environnante, se tournent vers le français central / le parisien standard du 21ème siècle, dans une approche étymologique donc, pour écrire le créole.

Résumé : International audience
1. Estimating forest above-ground biomass (AGB), or carbon (AGC), in tropical forests has become a majorconcern for scientists and stakeholders. However, AGB assessment procedures are not fully standardized andeven more importantly the uncertainty associated with AGB estimates is seldom assessed.2. Here, we present an R package designed to compute both AGB/AGC estimate and its associated uncertaintyfrom forest plot datasets, using a Bayesian inference procedure. The package builds upon previous work onpantropical and regional biomass allometric equations and published datasets by default but it can alsointegrate unpublished or complementary datasets in many steps.3. BIOMASS performs a number of standard tasks on input forest tree inventories: i) tree speciesidentification, if available, is automatically corrected; ii) wood density is estimated from tree species identity;iii) if height data are available, a local height-diameter allometry may be built; else height is inferred frompantropical or regional models; iv) finally, AGB/AGC are estimated by propagating the errors associated withall the calculation steps up to the final estimate. R code is given in the paper and in the appendix forillustration purpose.4. The BIOMASS package should contribute to improved standards for AGB calculation for tropical foreststands, and will encourage users to report the uncertainties associated with stand-level AGB/AGC estimatesin future studies.

Résumé : Research on natural insecticides has intensified with the spread of resistance to chemicals among insects, particularly disease vectors. To evaluate compounds, the World Health Organization (WHO) has published standardized procedures. However, those may be excessively compound-consuming when it comes to assessing the activity of natural extracts and pure compounds isolated in limited amount. As part of our work on the discovery of new mosquito larvicides from Amazonian plants, we developed a compound-saving assay in 5-ml glass tubes instead of WHO larval 100-m1 cups. Comparing activity of synthetic and natural chemicals validated the glass tube assay. Raw data, lethal doses that kill 50% (LD50) and 90% (LD90) at 24 and 48 h, were highly correlated (0.68 < R-2 < 0.96, P < 0.001, Pearson test) between cups and tubes. It was also established that 10 tubes (N = 50 larvae) provided the same level of sensitivity as 20 tubes (N= 100). This method proved suitable for rapid screening of natural extracts and molecules, identifying active compounds using 10 times less material than in the WHO protocol.

Résumé : A standardized rapid inventory method providing information on both tree species diversity and aboveground carbon stocks in tropical forests will be an important tool for evaluating efforts to conserve biodiversity and to estimate the carbon emissions that result from deforestation and degradation (REDD). Herein, we contrast five common plot methods differing in shape, size, and effort requirements to estimate tree diversity and aboveground tree biomass (AGB). We simulated the methods across six Neotropical forest sites that represent a broad gradient in forest structure, tree species richness, and floristic composition, and we assessed the relative performance of methods by evaluating the bias and precision of their estimates of AGB and tree diversity. For a given sample of forest area, a several small' (<1ha) sampling strategy led to a smaller coefficient of variation (CV) in the estimate of AGB than a few large' one. The effort (person-days) required to achieve an accurate AGB estimate (<10% CV), however, was greater for the smallest plots (0.1ha) than for a compromise approach using 0.5ha modified Gentry plots, which proved to be the most efficient method to estimate AGB across all forest types. Gentry plots were also the most efficient at providing accurate estimates of tree diversity (<10% CV of Hill number). We recommend the use of the 0.5ha modified Gentry plot method in future rapid inventories, and we discuss a set of criteria that should inform any choice of inventory method.

Résumé : International audience
Conventional quantitative electron probe microanalysis of actinides requires the use of reference standard samples. However, for such elements, standards are generally not available. To overcome this difficulty, standardless methods of analysis are used, in which the x-ray intensity emitted by the standard is calculated. To be reliable, such calculations require accurate knowledge of physical data such as the x-ray production cross section. However, experimental data of this quantity are not always available for actinide elements. In the present work, experimental L and M x-ray production cross sections were measured for elements uranium and lead. Measurements were performed with two electron microprobes using wavelength-dispersive spectrometers using thin self-supporting targets. Experimental results are compared with calculated cross sections obtained from different analytical formulae, and, whenever possible, with experimental data obtained from the literature.

Résumé : International audience
INTRODUCTION:The frequency, the clinical characteristics, and the prognosis of dengue is highly variable. Dengue fever is associated with a range of neurological manifestations. The objective of the present study was to determine the incidence of neurological signs and their predictive factors using data from cases of dengue seen and followed in Cayenne Hospital during the Dengue 2 epidemic in 2013.METHODS:In 2013, a longitudinal study using data from all cases of dengue seen in Cayenne hospital was collected. Medical records used a standardized form to collect demographic information, clinical signs and biological results and the date at which they were present. The analysis used Cox proportional modeling to obtain adjusted Hazard ratios.RESULTS:A total of 1574 patients were included 221 of whom developed central nervous system signs. These signs were spontaneously resolutive. There were 9298person days of follow-up and the overall incidence rate for central nervous system signs was 2.37 per 100 person-days. The variables independently associated with central nervous system anomalies were headache, Adjusted Hazard ratio (AHR) = 1.9(95%CI = 1.4-2.6), bleeding AHR = 2 ((95%CI = 1.3-3.1), P = 0.001, abdominal pain AHR = 1.9 ((95%CI = 1.4-2.6), P<0.001, aches AHR = 2.1 ((95%CI = 1.5-2.9), P<0.001, and fatigue AHR = 1.5 ((95%CI = 1.3-1.7), P<0.001.DISCUSSION:Overall, the present study suggests that neurological signs of dengue are not exceptional even in patients without the most severe features of dengue. These manifestations were spontaneously resolutive. Here it was not possible to distinguish between encephalitis or encephalopathy. Further studies would require more in depth exploration of the patients.

Résumé : This document is mainly a catalogue of the different types of fishing gears noticed all around Martinique during a ten years period (1985-1994)The technical description of these gears and their plans are presented, according to FAO standards. Besides these descriptions, the origins of the introduction in Martinique of the main categories of gears are related .Moreover,, the operating conditions of each fishing gear as well as the targeted species are dealt with. In addition, recent gears and techniques such as fishing aggregating devices (FADs) and associated fishing techniques are described. These ones appeared in Guadeloupe and Martinique during the last eighties years. Furthermore, the main characteristics of the martinican fishing fleet structure are mentioned at the beginning of this work, with a special attention to dug-out canoes, because of their progressive disappearance.

Résumé : Semi-volatile organic compounds (SVOCs) are widely present in indoor environments and are suspected to be repro- or neurotoxic but little is known on the health impact on SVOC mixtures. The objective of this work is to derive cumulative toxicity indicators for SVOCs detected in French dwellings in carrying forward a cumulative health risk assessment. SVOCs were grouped according to their repro- and neurotoxic common modes of action (i.e. decrease in serum testosterone concentrations, decrease in neuronal viability). Benchmark doses (BMDs) were then estimated by modeling dose-response relationships from scientific literature (Hill models, PROAST, RIVM). Comparable BMDs were estimated only for 6 of the 19 reprotoxic SVOCs which are responsible to 10 or 50% decrease in testosterone in adult male rats orally exposed. Estimated relative potency factors (RPFs) from BMDs are similar according to the response level (from 1600 for the B(a)P to 0.1 for the BBP), excepted for bisphenol A moving from 7E+6 to 180. For in vitro neuronal death, BMDs were estimated for 13 neurotoxic SVOCs using data from different cell lines and species. BMDs equivalent to a 10% of response range from 0.07 (PCB-153) to 95 µM (diazinon). The originality of this work is the grouping of compounds from different chemical families which we are really exposed to. BMDs estimation from published data was possible but many methodological limitations lead us to put forward recommendations especially on the standardization of experimental protocols and the availability of results in adapted format for dose-response relationship modeling.
Les composés organiques semi volatils (COSV) sont largement présents dans les environnements intérieurs et sont suspectés d’être repro- ou neurotoxiques, mais peu de données sont disponibles quant à leur toxicité en mélanges. L’objectif de cette thèse est de proposer des indicateurs de toxicité cumulés pour les COSV détectés dans les logements français, dans un cadre d’évaluation des risques sanitaires cumulés. Les COSV ont été regroupés en fonction de leurs modes d’action communs, en lien avec les effets reprotoxiques (diminution de la concentration de testostérone sérique) et neurotoxiques (diminution de la viabilité neuronale). Des benchmark doses (BMD) ont ensuite été estimées par modélisation (modèle de Hill, PROAST, RIVM) des relations dose-réponse de la littérature décrivant la réponse d’intérêt. Des BMD comparables ont pu être estimées seulement pour 6 des 19 COSV reprotoxiques induisant une diminution de testostérone de 10 ou 50 % chez le rat adulte exposé par voie orale. Les facteurs de toxicité relatifs (RPF) estimés à partir des BMD sont sensiblement les mêmes en fonction du niveau de réponse (de 1600 pour le B(a)P à 0,1 pour le BBP), excepté pour le biphénol A qui passe de 7E+6 à 180. Considérant la mort neuronale in vitro, des BMD ont pu être estimées pour 13 COSV neurotoxiques, à partir de données provenant de différentes lignées et espèces. Les BMD équivalent à un niveau de réponse de 10 % s’échelonnent de 0,07 (PCB-153) à 95 µM (diazinon). L’originalité de ce travail repose sur le regroupement de composés de familles chimiques différentes qui constituent des contaminations réelles de notre environnement. Si l’estimation des quelques BMD a été possible à partir des données de la littérature, de nombreuses limites méthodologiques conduisent à émettre des recommandations en particulier sur la standardisation des protocoles expérimentaux et la disponibilité des résultats sous une forme adaptée à la modélisation de la relation dose-réponse.

Résumé : International audience
BACKGROUND: Histoplasmosis is an endemic fungal infection in French Guiana. It is the most common AIDS-defining illness and the leading cause of AIDS-related deaths. Diagnosis is difficult, but in the past 2 decades, it has improved in this French overseas territory which offers an interesting model of Amazonian pathogen ecology. The objectives of the present study were to describe the temporal trends of incidence and mortality indicators for HIV-associated histoplasmosis in French Guiana. METHODS: A retrospective study was conducted to describe early mortality rates observed in persons diagnosed with incident cases of HIV-associated Histoplasma capsulatum var. capsulatum histoplasmosis admitted in one of the three main hospitals in French Guiana between 1992 and 2011. Early mortality was defined by death occurring within 30 days after antifungal treatment initiation. Data were collected on standardized case report forms and analysed using standard statistical methods. RESULTS: There were 124 deaths (45.3%) and 46 early deaths (16.8%) among 274 patients. Three time periods of particular interest were identified: 1992-1997, 1998-2004 and 2005-2011. The two main temporal trends were: the proportion of early deaths among annual incident histoplasmosis cases significantly declined four fold (χ2, p<0.0001) and the number of annual incident histoplasmosis cases increased three fold between 1992-1997 and 1998-2004, and subsequently stabilized. CONCLUSION: From an occasional exotic diagnosis, AIDS-related histoplasmosis became the top AIDS-defining event in French Guiana. This was accompanied by a spectacular decrease of early mortality related to histoplasmosis, consistent with North American reference center mortality rates. The present example testifies that rapid progress could be at reach if awareness increases and leads to clinical and laboratory capacity building in order to diagnose and treat this curable disease.

Résumé : International audience
Saccharopolyspora rectivirgula is the principal cause of farmer's lung disease (FLD). Serodiagnosis is based on immunoprecipitation techniques or enzyme immunoassays with homemade crude antigens and is not standardized. We aimed to produce specific recombinant antigens for the development of a standardized ELISA. We recruited 41 patients and 43 healthy exposed controls from five university hospital pneumology departments in France and Switzerland. S. rectivirgula proteins were extracted, separated by 2D electrophoresis, and subjected to Western blotting, with sera from FLD patients or controls. FLD-specific proteins were identified by MS and were produced as recombinant antigens. The diagnostic performance of ELISA tests using the recombinant antigens was assessed with all the sera from FLD patients and controls. We identified 25 FLD-specific proteins, some of which play important roles in transport, nutrition, or virulence. We produced 17 of these proteins as recombinant antigens and assessed their suitability for inclusion in the ELISA test. A combination of three of these proteins (SR1FA, SR17, and SR22) proved remarkably effective at discriminating between patients and controls, with a sensitivity of 83% and a specificity of 77%. The recombinant antigens produced in this study constitute a major step toward the improvement of diagnostic performance and the standardization of FLD serodiagnosis.

Résumé : Absolute Mα and Mβ X-ray intensities were measured for the elements Pt, Au, Pb, U, and Th by electron impact for energies ranging from 6 to 38 keV. Experimental data were obtained by measuring the X-ray intensity emitted from bulk samples with an electron microprobe using high-resolution wavelength-dispersive spectrometers. Recorded X-ray intensities were converted into absolute X-ray yields by evaluation of the detector efficiency and then compared with X-ray intensities calculated by means of Monte Carlo simulations. Simulated Mα and Mβ X-ray intensities were found to be in good agreement with the measurements, allowing their use in standardless quantification methods. A procedure and a software program were developed to accurately obtain virtual standard values. Standardless quantifications of Pb and U were tested on standards of PbS, PbTe, PbCl2, vanadinite, and UO2.

Résumé : International audience
Primary spontaneous pneumothorax (PSP) is common and affects young and active patients. Guidelines are accurate about diagnosis and treatment indications, but the initial optimal management remains unclear. Smoking is the main risk factor and smoking cessation must be systematically advised. If simple surveillance is acceptable for small PSP and/or paucisymptomatic patient with PSP, exsufflation or hospitalization with chest tube drainage remains the standard treatment in other situations. Ambulatory management is possible and could become the next standard of care. © 2015, Société de réanimation de langue française (SRLF) and Springer-Verlag France

Résumé : International audience
MOTIVATION: Imaging mass spectrometry (IMS) is a maturating technique of molecular imaging. Confidence in the reproducible quality of IMS data is essential for its integration into routine use. However, the predominant method for assessing quality is visual examination, a time consuming, unstandardized and non-scalable approach. So far, the problem of assessing the quality has only been marginally addressed and existing measures do not account for the spatial information of IMS data. Importantly, no approach exists for unbiased evaluation of potential quality measures. RESULTS: We propose a novel approach for evaluating potential measures by creating a gold-standard set using collective expert judgements upon which we evaluated image-based measures. To produce a gold standard, we engaged 80 IMS experts, each to rate the relative quality between 52 pairs of ion images from MALDI-TOF IMS datasets of rat brain coronal sections. Experts' optional feedback on their expertise, the task and the survey showed that (i) they had diverse backgrounds and sufficient expertise, (ii) the task was properly understood, and (iii) the survey was comprehensible. A moderate inter-rater agreement was achieved with Krippendorff's alpha of 0.5. A gold-standard set of 634 pairs of images with accompanying ratings was constructed and showed a high agreement of 0.85. Eight families of potential measures with a range of parameters and statistical descriptors, giving 143 in total, were evaluated. Both signal-to-noise and spatial chaos-based measures performed highly with a correlation of 0.7 to 0.9 with the gold standard ratings. Moreover, we showed that a composite measure with the linear coefficients (trained on the gold standard with regularized least squares optimization and lasso) showed a strong linear correlation of 0.94 and an accuracy of 0.98 in predicting which image in a pair was of higher quality.
