Résumé : International audience
CONTEXT: Chlordecone, an environmentally persistent organochlorine insecticide used intensively in banana culture in the French West Indies until 1993, has permanently polluted soils and contaminated foodstuffs. Consumption of contaminated food is the main source of exposure nowadays. We sought to identify main contributors to blood chlordecone concentration (BCC) and to validate an exposure indicator based on food intakes. MATERIAL AND METHODS: We used a food frequency questionnaire (FFQ) completed by a sample of 194 pregnant women to estimate their dietary exposure to chlordecone and compared it to blood levels. In a first approach, chlordecone daily intake was estimated as the product of daily eaten quantity of 214 foodstuffs, multiplied by their chlordecone content, and summed over all items. We then predicted individual blood chlordecone concentration with empirical weight regression models based on frequency of food consumption, and without contamination data. RESULTS: Among the 191 subjects who had BCC determination, 146 (76%) had detectable values and mean BCC was 0.86 ng/mL (range < LOD-13.2). Mean per capita dietary intake of chlordecone was estimated at 3.3 microg/day (range: 0.1-22.2). Blood chlordecone levels were significantly correlated with food exposure predicted from the empirical weight models (r=0.47, p<0.0001) and, to a lesser extent, with chlordecone intake estimated from food consumption and food contamination data (r=0.20, p=0.007). Main contributors to chlordecone exposure included seafood, root vegetables, and Cucurbitaceous. CONCLUSION: These results show that the Timoun FFQ provides valid estimates of chlordecone exposure. Estimates from empirical weight models correlated better with blood levels of chlordecone than did estimates from the dietary intake assessment.

Résumé : Crayfishing is not particularly organized in the French islands as their population is not fond of large crustaceans. However, young crayfishes, about the size of the European scampi are ordered by rich Creoles for receptions or family gatherings. But lobsters, heavier than 0.750 to 1 kilo are eaten only by Europeans.Any fisherman who is asked to provide 10 kilos of crayfish catches them very quickly with a brass snare or a hook placed underneath the rocks. Some artisans gather the crustaceans in large rectangular baskets made of wire mesh and called "gardes", to wait for the potential customer. There is no specific pot for this type of fishing whereas Creole wicker makers worked hard on the creation of tools both complex and difficult to make to catch small morays; a fish which does not have a great commercial value.Consequently, it is impossible to precisely assess the importance of the exploitable large crustacean stock based on the catches of the Creole fishermen. If the performances of some crayfish boats from Douarnenez, using Mauritanian nets on the banks of St-Martin, can be considered as extremely satisfactory, it is not the case of other attempts. A whole study has to be undertaken. This note is only the beginning of a larger work focusing on the natural history of the crayfishes and Spanish lobsters in the waters of the arc of the Petites Antilles.
La pêche des langoustes n'est pas spécialement organisée dans les îles françaises, la population n'étant que peu friande de gros crustacés. Toutefois de jeunes langoustes, de la taille de la langoustine européenne sont commandées aux pêcheurs par les riches créoles, à l'occasion de réceptions ou de fêtes familiales; mais les « homards») dépassant le poids de 0,750 à 1 kilo sont consommés seulement par les Européens. Le pêcheur. auquel on demande de fournir 10 kilos de langoustes, les capture rapidement au collet de laiton ou au crochet sous les cayes, Certains artisans rassemblent les crustacés dans de grandes nasses rectangulaires de grillage métallique, appelées « gardes », en attendant l'acheteur éventuel. Il n'existe pas de type de casier spécial à cette pêche, alors que les vanniers créoles se sont ingéniés, par exemple, à créer des engins compliqués et difficiles à construire pour capturer les petites murènes appelées « moringues » qui n'ont pourtant que peu de valeur commerciale. Il est donc impossible de se faire une idée précise de l'importance du stock de gros crustacés exploitable en se basant sur les apports des pêcheurs créoles. Si les rendements de certains langoustiers douarnenistes, travaillant au filet mauritanien sur les bancs de St-Martin, ont pu être considérés comme extrêmement satisfaisants, il n'en est pas de même à propos d'autres tentatives. Il y a là toute une étude à entreprendre. Cette note n'est que le début d'un travail concernant l'histoire naturelle des langoustes et scyllares des eaux de l'arc des Petites Antilles.

Résumé : International audience
BACKGROUND: Recent studies suggest that a Mediterranean dietary pattern during pregnancy may influence pregnancy outcomes. The aim of this study was to evaluate the effect of adherence to a Mediterranean diet (MD) during pregnancy on fetal growth restriction (FGR) and preterm delivery (PTD) in a French Caribbean island where the population is largely of African descent and presents dietary patterns similar to MD. METHODS: Using data from the TIMOUN Mother-Child Cohort Study conducted in Guadeloupe (French West Indies) between 2004 and 2007, we analysed data for 728 pregnant women who delivered liveborn singletons without any major congenital malformations. Degree of adherence to MD during pregnancy was evaluated with a semi-quantitative food frequency questionnaire based on nine dietary criteria. Multiple logistic regression models were used to analyse birth outcomes while taking potential confounders into account. RESULTS: Overall there was no association between MD adherence during pregnancy and the risk of PTD or FGR. However, pre-pregnancy body mass index was a strong effect modifier, and MD adherence was associated with a decreased risk of PTD specifically in overweight and obese women (adjusted odds ratio 0.7, 95% confidence interval 0.6, 0.9) (P heterogeneity <0.01). CONCLUSIONS: These results suggest that Caribbean diet during pregnancy may carry some benefits of MD and may contribute to reduce the risk of PTD in overweight and obese pregnant women.

Résumé : International audience
Background: End-Stage renal disease (ESRD) causes considerable morbidity and mortality, and significantly alterspatients’ quality of life. There are very few published data on this problem in the French Overseas territories. Thedevelopment of a registry on end stage renal disease in French Guiana in 2011 allowed to describe the magnitudeof this problem in the region for the first time.Methods: Using data from the French Renal Epidemiology and Information Network registry (R.E.I.N). Descriptivestatistics on quantitative and qualitative variables in the registry were performed on prevalent cases and incidentcases in 2011, 2012 and 2013.Results: French Guiana has one of the highest ESRD prevalence and incidence in France. The two main causes ofESRD were hypertensive and diabetic nephropathies. The French Guianese population had a different demographicprofile (younger, more women, more migrants) than in mainland France. Most patients had at least one comorbidity,predominantly (95.3%) hypertension. In French Guiana dialysis was initiated in emergency for 71.3% of patients versus33% in France (p < 0.001).Conclusion: These first results give important public health information: i) End stage renal disease has a very highprevalence relative to mainland France ii) Patients have a different demographic profile and enter care late in thecourse of their renal disease. These data are closer to what is observed in the Caribbean or in Latin America than inMainland France.

Résumé : This paper describes the fishing activity in Martinique, French West Indies. It draws up the balance sheet of acquirements about marine resources of the island. The difficulties of fisheries management are discussed with reference to biologists and economists works in the last ten years. We also show how management efforts to decrease fishing pressure on reef resources has induced the implantation of a new technology: the Fish Aggregating Deviee. The differing histories of development of FADs in the French West Indies are compared. The positive results from the introduction of the FADs and the estimated risks due to the transferance of fishing pressure on the continental shelf is presented. The use of FADs to enhance the exploitation of marine resources is a concept that justifies.a cooperative plan throughout the Caribbean region
A partir d'une présentation synthétique de l'activité de pêche en Martinique, cette note dresse le bilan des connaissances actuelles sur l'état des ressources halieutiques de l'île. Les difficultés de la gestion des pêches sont discutées en référence aux travaux réalisés par les halieutes et les économistes des pêches au cours des dix dernières années. On montre comment un objectif de gestion, l'allégement de la pression de pêche sur les ressources démersales, a pu conduire à l'implantation d'une nouvelle technologie: le dispositif de concentration de poissons. Les différents contextes de développement des DCP observés dans les deux départements français des Antilles sont comparés. Les retombées positives de l'introduction des dispositifs sont évaluées mais le risque d'aboutir à un report d'une partie de la puissance de pêche sur le plateau est également évoqué. L'influence du DCP sur l'exploitation des ressources halieutiques constitue un argument supplémentaire pour intensifier la coopération caribéenne sur ce thème

Résumé : Since the beginning of 1980, the Martinique fishermen have suffered a deep crisis. The traditional ways of fishing, based on benthic fish exploitation, have seen the decreasing of their profitability due to the over-fishing of the narrow continental shelf offering few resources. The pelagic fishery had become the professional main source of income. This fishery equally encounter difficulties: denied rights of access in the EEZ of Caribbean islands, expensive costs of exploitation. The disposal of FADs offers new ways to the Martinique fishermen. In 1999, it was decided the disposal of a onetworko of 30 permanent FADs around Martinique. The mooring of these FADs must be followed by legal and economic adapted measures to reach the desired aim: the development of local fishery economy through a sustainable fishing practice. Therefore, the French authorities have decided to make the regional fishermen committee responsible for the management of FADs.This committee is the only one to be entitled to moor and to deliver licences to FADs. This committee, gathering all the fishing industry representatives, has regarding the french law the right of mooring and delivering licences to the FADs access, collecting fishery statistics. These data should fund research to improve the management of the fishery, care and replace FADs. This programas realisation, as well as durability, need adequate financial planning. It has been included in the European commission financing program. This plans success will ensure the increase of the fishermen income, maintain and develop employment.Original Abstract: Apres une periode d'experimentation lancee localement au debut des annees quatre-vingt, les premiers resultats ont ete suffisamment probants pour conduire les professionnels a souhaiter l'implantation de dispositifs de concentration de poissons (dcp) en Martinique ou a les implanter eux-memes pour la capture des dorades coryphenes, des thons noirs, de l'albacore ou du listao. Le colloque international sur la peche thoniere et les dispositifs de concentration de poissons organise du 15 au 19 octobre 1999 en Martinique donne l'occasion de revenir sur le contexte, l'interet et les modalites de developpement de la technique des dcp en Martinique.

Résumé : From February to June 1951 the "Président-Théodore-Tissier" sailed all the way to the French Caribbean, via Madeira, then to the coasts of Nova Scotia, on the banks of Newfoundland, via the Bermudas, and back to Lorient via the Azores Islands. During this cruise, an important material was sampled by A. Bourdillon, Research Attaché in the Marine Station of Endoume and invited by the Scientific and Technical Institute of Marine Fisheries. Ascidians form the greatest share of this material. They can be grouped in four batches: French Caribbean, Bermudas, Nova Scotia, and Newfoundland. But the French Caribbean batch and that of Newfoundland are by far the most interesting, considering the number and variety of the species they hold. From a geographic point of view, only two groups are worth being studied: 1° The French Caribbean batch which contains only tropical species, to which can be linked the Bermudas batch, islands which although located at a high latitude benefit from a subtropical hydrological regime. 2° The Newfounland batch, which has a cold character, and to which can be linked the Nova Scotia batch.
Pendant la période allant du mois de février au mois de juin 1951 le « Président-Théodore-Tissier » a effectué une longue croisière qui, par Madère, l'a mené jusqu'aux Antilles françaises, puis par les Bermudes et les côtes de Nouvelle-Ecosse sur les bans de Terre-Neuve, le cheminl du retour ver Lorient passant par les Açores. Durant cette campagne, un matériel important a été prélevé par A. Bourdillon, attaché de Recherche à la station Marine d'Endoume, invité par l'lnstitut Scientifique et technique des Pêches maritimes pour participer à la croisière. [OCR NON CONTRÔLE] Les ascidies constituent une part importante de ce matériel. Elles peuvent se répartir en quatre lots : Antilles françaies, Bermudes, Nouvelle-Ecosse, Terre-Neuve. Mais le lots de Antilles Française principalement et celui de Terre-Neuve sont de beaucoup les plus intéressants par le nombre et la variété des espèces qu'ils renferment. Du point de vue géographique, deux groupes seulement sont à considérer : 1° Le groupe des Antilles françaises ne renfermant que des espèces de caratères tropical et auquel on peut rattacher le groupe des Bermudes, îles qui malgré leur latitude assez élevée bénéficient d'un régime hydrologique subtropical. 2° Le groupe de Terre-Neuve à caractère froid auquel se rattache le groupe de Nouvelle Ecosse.

Résumé : Lessons for the future from two development projects in aquaculture in the French overseas territories. Numerous research and development projects have been launched since the seventies in the French overseas territories. Their aim was to foster new activities in agriculture based on local productions for local markets, notably in the French West Indies (FWI). In this paper we analyze two development projects on the rearing of giant freshwater prawn, one in the FWI and the other in French Guyana, over twenty years after their launching. The purpose of these compared studies is twofold: first to try to understand why a set of relevant technical innovations ended in failure 15 years later; second to identify recommendations in terms of methodology in order to diminish risks of mistakes or failure for future projects. To reach this goal we followed two approaches. A first analysis is based on a set of three criteria: social acceptability, legitimacy and time planning. The second analysis, justified by the subjective need for an explanatory tool, is based on the actor-network theory. The results show that beyond the levels of political support and financial investment and support the three key criteria for success are: (i) reactivity of the decision-makers, notably when markets change, (ii) quality of leadership transfer between the launching phase and the stabilized phase, and (iii) capacity of the decision-makers to take into account the concrete consequences of the various scenarios. Regarding this third criterion, our analysis suggests that the scenario of full technical success needs to be explored, notably in terms of economic sustainability. The integration of these two types of analyses into an ex-ante frame should contribute to reducing risks of failure in similar development projects.
De nombreux projets d’aquaculture ont été menés depuis les années 1970 dans les territoires et départements français d’outre-mer. L’objectif était de diversifier l’agriculture avec des productions destinées au marché local comme aux Antilles, ou à l’exportation comme en Guyane. L’étude s’intéresse au bilan de deux projets d’élevage de la crevette tropicale d’eau douce aux Antilles et en Guyane, plus de vingt ans après leur lancement. L’objectif est de comprendre comment des innovations technologiques pertinentes ont conduit à deux échecs sur le moyen terme et de tirer des recommandations de méthode afin de réduire les risques d’erreurs ultérieures. Pour cela, deux cadres d’analyse sont mobilisés : le premier s’appuie sur les concepts de temporalité, légitimité et acceptabilité ; le second, motivé par la recherche subjective de cadres explicatifs, emprunte la vision de la théorie de l’acteur-réseau. Les trois déterminants majeurs du succès ou de l’échec se révèlent être la réactivité des responsables face aux problèmes d’adaptation à l’évolution des marchés, la qualité du transfert du leadership lors du passage de la phase de lancement à la phase de croisière et enfin la capacité de prendre en compte dès le départ les conséquences des scénarios d’évolution du projet, y compris la réussite technique. Une capacité d’intégration de ces types d’analyse, dans un cadre ex ante, devrait permettre de réduire les risques d’échec dans des projets de développement similaires à venir.

Résumé : In a perfect-deficit approach (Yi, 2012), the daily maximum carbon storage capacity (CPC) of a given ecosystem for each year defines the perfect annual CPC curve. Deficits are the differences in the daily observational data for a given year against a perfect curve. The area between this curve and instantaneous canopy photosynthetic rates represents the potential productivity. Using an 11-year (2004 – 2014) eddy covariance flux and meteorological data, this perfect-deficit approach was used to examine the relationship between potential productivity and droughts occurring in 2005 and 2010 in a tropical rainforest of French Guiana, South America. Surprisingly, CPC deficits were only reduced by 24% (2005) and 19% (2010) from their respective perfect CPCs, indicating a subtle effect of drought to ecosystem productivity. Highest precipitation occurred in 2010 but precipitation deficits dropped drastically during this year (71% reduction from its perfect value) which reflects a drought condition. However, its deficits showed no correlation annually and seasonally. Soil water content (SWC) appeared to be the single driver for CPC deficits during long dry periods but is weakly correlated (r = 0.30; P <0.01 and r = 0.31; P <0.01, in 2005 and 2010, respectively). These results indicate that soil water is not a major limiting factor for productivity of this ecosystem during drought periods. In contrast, global radiation (Rg) corresponds to the peak of CPC deficits in 2010, but only 19% had been reduced from its ideal value. Yet, highest gross primary production (GPP) of 4106±231 gCm−2yr−1 occurred this year (mean 3753±231 gCm−2yr−1). Therefore, smaller deficits in Rg coupled with sufficient water may have induced higher productivity in 2010. Nevertheless, weaker correlations between potential productivity and climatic drivers may imply that other controlling aspects such as biological constraints may also have an effect to the dynamics of potential productivity during drought events, hence, must also be considered.

Résumé : Does the language in which the instructions are formulat- ed affect the execution of a bilingual's motor task? The first experiment studies whether the language used for the instructions influences the motor performances among bilingual children in situation of learning. Eighty bilin-gual French/Creole children (age means 10.4) were distributed into two experimental groups to learn how to perform a motor task. One group received instructions in French and the other one in Creole. The data suggest that the language of presentation affects the execution of a motor task. Both groups had the same performance level at the beginning of the experiment. We noticed that the group taught in Creole obtained better performances than the group taught in French at the end of the learning situation. The results are discussed in terms of their implications to physical education and motor rehabilitation of bilinguals. The two following experiments reported in the present paper concern (i) the differential imagery value of French and Creole and (ii) the influence of language on the recall of sequences of patterned movements in a bilingual population. Creole words were obtained a higher imagery value than French words, certainly because Creole is an oral and vernacular language. Motor recall scores were better when the sequence was presented in Creole compared to French. The generation of visual images by Creole would facilitate the memorization and recall of new sequences of movements. The effect of language on imagery value of words and motor recall among bilingual French–Creole subjects was discussed in terms of nature of information encoding in each language. The goal of the fourt and last study tries to know the language impact on the movement imagery ability of guadeloupean children. A person is able to represent verbal information with an image (Denis, 1989; Paivio, 1986). The language can he influence this ability on bilingual individuals? If Creole has more to do with image than French (Michelot, 2000), this survey considers a distinct language influence on the mental images vividness specified by guadeloupean children. 123 secondary school pupils (average age 13.45) altogether accepted to fill in the Movement Imagery Questionnaire of Hall and Pongrac (1983). This test enables to measure the rapidity of visual and kinaesthetic images. The “Creole” group (59 children; average age 13. 43) got the MIQ translated in Creole and the “French” group (64 children; average age 13.46) the French version of the test. Finally, language does not generally influence the movement imagery capacity. Yet, the kinaesthetic images are more vivid in French than in Creole for the subjects tested, aged from 11 to 13. The subjects aged from 14 to 16 have, only in Creole, more vivid visual images than the subjects aged from 11 to 13. The language affects the movement imagery ability with age of this guadeloupean children.
L'exécution d'une tâche motrice chez des bilingues est-elle affectée par la langue dans laquelle les consignes sont formulées ? Une première expérience a été menée en vue d'analyser si la langue de présentation des consignes influence les performances motrices d'enfants bilingues en situation d'apprentissage. Quatre-vingt bilingues français/créole (âge moyen : 10,4 ans) ont été répartis dans deux groupes expérimentaux afin d'apprendre à réaliser une tâche motrice, l'un recevant les consignes en français et l'autre en créole. Les données suggèrent que la langue de présentation affecte l'exécution d'une tâche motrice. Le groupe enseigné en créole obtient de meilleures performances en fin d'apprentissage comparativement à celles obtenues par le groupe enseigné en français, alors que les deux groupes ont au départ un niveau comparable. Ces résultats sont discutés sur le plan de leur implication pour l'éducation physique et la réadaptation motrice des bilingues. Les deux expérimentations suivantes évaluent (i) la valeur d'imagerie de mots et (ii) le rappel moteur d'enchaînements auprès de bilingues français–créole en faisant varier la langue de présentation. Les mots en créole, supposés susciter plus facilement des images mentales visuelles, car le créole est une langue orale et vernaculaire, ont effectivement obtenu une cote plus élevée que les mots français sur l'échelle de valeur d'imagerie. L'évocation d'images visuelles facilitant la mémorisation et la planification de séquences de mouvements, les performances de rappel obtenues à partir des consignes en créole ont été supérieures à celles obtenues en français. Les effets de la langue de présentation sur la valeur d'imagerie des mots et le rappel moteur d'enchaînements de morphocinèses auprès des participants bilingues sont discutés en termes de nature d'encodage de l'information verbale dans chacune des langues. L'objectif de cette quatrième et dernière recherche est de connaître l'impact de la langue sur la capacité d'imagerie du mouvement d'enfants guadeloupéens. Un individu peut se représenter des informations verbales sous une forme imagée (Denis, 1989; Paivio, 1986). La langue peut-elle influencer cette capacité chez des individus bilingues ? Le créole étant plus imagé que le français (Michelot, 2000), nous prévoyons une influence distincte de la langue sur le degré de vivacité des images mentales. Cent-vingt-trois collégiens guadeloupéens (âge moyen 13.45) ont rempli un questionnaire d'imagerie du mouvement (MIQ de Hall et Pongrac, 1983) mesurant la vivacité d'images visuelles et kinesthésiques. Un groupe «créole» (59 enfants; âge moyen 13.43) l'a passé en créole et un groupe «français» (64 enfants; âge moyen 13.46) en français. Finalement, la langue n'influence pas la capacité d'imagerie mentale de notre échantillon. Mais la vivacité des images kinesthésiques est supérieure en français chez les sujets de 11 à 13 ans et celle des images visuelles des sujets de 14 à 16 ans est supérieure à celle des sujets de 11 à 13 ans seulement en créole. La langue semble influencer la capacité d'imagerie mentale des sujets en fonction de l'âge.

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
This paper aims to decipher the thermal evolution of the Montagne Noire Axial Zone (MNAZ,southern French Massif Central) gneiss core and its metasedimentary cover through determination ofP–T paths and temperature gradients. Migmatitic gneiss from the core of the dome record a clock-wise evolution culminating at 725 25 °C and 0.8 0.1 GPa with partial melting, followed by adecompression path with only minor cooling to 690 25° C and 0.4 0.1 GPa. Field structuralanalyses as well as detailed petrological observations interpreted in a petrogenetic grid indicate thatthe cover sequence experienced LP-HT metamorphism at <0.4 GPa. Apparent thermal gradientswithin the cover were determined with garnet–biotite thermometry and Raman Spectroscopy on Car-bonaceous Matter. High-temperature apparent gradients (e.g. 530 °C km1 along one transect) areexplained by late brittle–ductile extensional shearing evidenced by phyllonites that post-date peakmetamorphism. In areas where normal faults are less abundant and closely spaced, gradients of 20to 50 °C km1 are calculated. These gradients can be accounted for by a combination of domeemplacement and ductile shearing (collapse of isotherms), without additional heat input. Finally, thethermal evolution of the MNAZ is typical for many gneiss domes worldwide as well as with otherLP-HT terranes in the Variscides.

Résumé : International audience
Malaria remains one of the most common vector-borne diseases in the world and the definition of novel control strategies can benefit from the modeling of transmission processes. However, data-driven models are often difficult to build, as data are very often incomplete, heterogeneous in nature and in quality, and/or biased. In this context, a knowledge-based approach is proposed to build a robust and general landscape-based hazard index for malaria transmission that is tailored to the Amazonian region. A partial knowledge-based model of the risk of malaria transmission in the Amazonian region, based on landscape features and extracted from a systematic literature review, was used. Spatialization of the model was obtained by generating land use and land cover maps of the cross-border area between French Guiana and Brazil, followed by computing and combining landscape metrics to build a set of normalized landscape-based hazard indices. An empirical selection of the best index was performed by comparing the indices in terms of adequacy with the knowledge-based model, intelligibility and correlation with P. falciparum incidence rates. The selected index is easy to interpret and successfully represents the current knowledge about the role played by landscape patterns in malaria transmission within the study area. It was significantly associated with P. falciparum incidence rates, using the Pearson and Spearman correlation coefficients (up to 0.79 and 0.75, respectively; p-value < 0.001), and the linear regression coefficient of determination (reaching 0.63; p-values < 0.001). This study establishes a spatial knowledge-driven, landscape-based hazard malaria index using remote sensing that can be easily produced on a regular basis and might be useful for malaria prediction, surveillance, and control. Keywords: remote sensing; land use and land cover; landscape metric; knowledge-based hazard modeling; malaria; cross-border area between French Guiana and Brazil

29 inorganic compounds (Al, As, B, Ba, Be, Bi, Ca, Cd, Ce, Co, Cr, Cu, Fe, Gd, K, Mg, Mn, Mo, Na, Nd, Ni, Pb, Sb, Se, Sr, Ti, U, V and Zn) were measured in the tap water of 484 representative homes of children aged 6 months to 6 years in metropolitan France in 2008-2009. Parents were asked whether their children consumed tap water. Sampling design and sampling weights were taken into account to estimate element concentrations in tap water supplied to the 3,581,991 homes of 4,923,058 children aged 6 months to 6 years. Median and 95th percentiles of concentrations in tap water were in mu g/L: Al: <10, 483, As: 02, 2.1; B: <100, 100; Ba: 30.7, 149.4; Ca: 85,000, 121,700; Cd: <0.5, <0.5; Ce: <0.5, <0.5; Co: <0.5, 0.8; Cr: <5, <5; Cu: 70, 720; K: 2210, 6740; Fe: <20, 46; Mn: <5, <5; Mo: <0.5,1.5; Na: 14,500, 66,800; Ni: <2,10.2; Mg: 6500,21,200; Pb: <1, 5.4; Sb: <0.5, <0.5; Se: <1, 6.7; Sr: 256.9, 1004; TI: <0.5, <0.5; U: <0.5, 2.4; V: <1, 1; Zn; 53, 208. Of the 2,977,123 young children drinking tap water in France, some were drinking water having concentrations above the 2011 World Health Organization drinking water quality guidelines: respectively 498 (CI 95%: 0-1484) over 700 mu g/L of Ba; 121,581 (CI 95%: 7091-236,070) over 50 mg/L of Na; 2044 (CI 95%: 0-6132) over 70 mu g/L of Ni, and 78,466 (17,171-139,761) over 10 mu g/L of Pb. Since it is representative, this tap water contamination data can be used for integrated exposure assessment, in conjunction with diet and environmental (dust and soil) exposure data.

Résumé : International audience
In disease-endemic areas, histoplasmosis is the main differential diagnosis for tuberculosis among human immunodeficiency virus (HIV)-infected patients. However, no study has compared the two diseases. Thus, the objective of this study was to compare tuberculosis and histoplasmosis in HIV-infected patients. A population of 205 HIV-infected patients (99 with tuberculosis and 106 with histoplasmosis) hospitalized in Cayenne, French Guiana during January 1, 1997-December 31, 2008 were selected retrospectively from the French Hospital Database on HIV. Multivariate analysis showed that tuberculosis was associated with cough (adjusted odds ratio [AOR] = 0.20, 95% confidence interval [CI] = 0.05-0.73) and a C-reactive protein level > 70 mg/L (AOR = 0.98, 95% CI = 0.97-0.99). Variables associated with disseminated histoplasmosis were a γ-glutamyl transferase level > 72 IU/L (AOR = 4.99, 95% CI = 1.31-18.99), origin from French Guiana (AOR = 5.20, 95% CI = 1.30-20.73), disseminated localization (AOR = 6.40, 95% CI = 1.44-28.45), a concomitant opportunistic infection (AOR = 6.71, 95% CI = 1.50-29.96), a neutrophil count < 2,750 cells/mm(3) (AOR = 10.54, 95% CI = 2.83-39.24), a CD4 cell count < 60 cells/mm(3) (AOR = 11.62, 95% CI = 2.30-58.63), and a platelet count < 150,000/mm(3) (AOR = 19.20, 95% CI = 3.35-110.14). Tuberculosis and histoplasmosis have similarities, but some factors show a greater association with one of these diseases. Thus, adapted therapeutic choices can be made by using simple clinical and paraclinical criteria.

Résumé : The availability in interesting sites and the zootechnical performances of tropical fish are two impo rt ant assets in favor of the development of fish farming in the Caribbean islands. This repor presents a technical and financial analysis of red drum farming projects in floating cages in Martinique(French West Indies). This project analysis makes it possible to compare the economic feasability of a small-scale production system with that of a semi-industrial one submitted to different technical constraints. The main criteria of the project analysis are the profitability of the funded capital, the financial feasability during the buildup period, the profitability at a steady state and the cost price. Production costs are hi gher in the the small-scale enterprises than in the semi-industrial ones, thanks to better capita] productivity and better labour productivity. An analysis of sensitivity to the variations ofbiological and economical parameters is also contained in the report. The results of these studies indicate that Caribbean fish farming could be profitable, due to the rapid buildup of the facilities and to the short production cycles. Nevertheless, attention should be paid to the risk of storms and hurricanes in this part of the world. Moreover, the analysis of sensitivity highlights the great influence of seed price.

Les bonnes performances zootechniques des poissons tropicaux et la disponibilité en sites propices sont deux atouts majeurs favorables au développement de l'aquaculture de poissons dans les îles des Caraïbes. Ce rapport présente l'adaptation d'un outil de simulation technico- économique à l'éleva ge de l'ombrine en cages flottantes dans le contexte martiniquais. Cet outil permet de disposer d'éléments de comparaison sur la faisabilité de deux systèmes de production, Fun de type artisanal et l'autre de type semi- industriel, soumis à des contraintes techniquesdifférentes : rentabilité du capital investi, faisabilité financière au démarrage, rentabilité en année de routine, prix de revient. Une analyse de sensibilité des résultats aux variations de paramètres biologiques et économiques est également présentée. L'analyse de ces projets fait apparaître une rentabilité satisfaisante de l'activité, liée à la rapidité de mise en route des installations et à la brièveté des cycles de production. Line grande attention doit être cependant portée sur les risques d'accidents climatiques fréquents dans cette région du globe (cyclone, mais aussi tempête...). L'analyse de sensibilité montre la grande influence du prix d'achat de l'alevin, en particulier sur les résultats de la variante artisanale, dont le coût de production de l'ombrine rendue à quai, est plus élevé que celui de la variante semi- industrielle.

Résumé : International audience
BACKGROUND: Women of reproductive age can be exposed to endocrine-disrupting chemicals (EDCs) at work, and exposure to EDCs in pregnancy may affect fetal growth. OBJECTIVES: We assessed whether maternal occupational exposure to EDCs during pregnancy as classified by application of a job exposure matrix was associated with birth weight, term low birth weight (LBW), length of gestation, and preterm delivery. METHODS: Using individual participant data from 133,957 mother-child pairs in 13 European cohorts spanning births from 1994 through 2011, we linked maternal job titles with exposure to 10 EDC groups as assessed through a job exposure matrix. For each group, we combined the two levels of exposure categories (possible and probable) and compared birth outcomes with the unexposed group (exposure unlikely). We performed meta-analyses of cohort-specific estimates. RESULTS: Eleven percent of pregnant women were classified as exposed to EDCs at work during pregnancy, based on job title. Classification of exposure to one or more EDC group was associated with an increased risk of term LBW [odds ratio (OR) = 1.25; 95% CI: 1.04, 1.49], as were most specific EDC groups; this association was consistent across cohorts. Further, the risk increased with increasing number of EDC groups (OR = 2.11; 95% CI: 1.10, 4.06 for exposure to four or more EDC groups). There were few associations (p < 0.05) with the other outcomes; women holding job titles classified as exposed to bisphenol A or brominated flame retardants were at higher risk for longer length of gestation. CONCLUSION: Results from our large population-based birth cohort design indicate that employment during pregnancy in occupations classified as possibly or probably exposed to EDCs was associated with an increased risk of term LBW.
