Description : Les professeurs Cécile Bertin-Elisabeth et Dominique Berthet ouvrent le colloque consacré à la prégnance du lieu dans la Caraïbe. Après la présentation de quelques oeuvres originales exposées dans l'amphithéâtre, ils ouvrent la problématique sur le lieu et la présentation de l'espace Caraïbe. Le lieu est incontournable et la question de la relation au lieu est également incontournable, l'homme agit sur le lieu et s'adapte au lieu. Le lieu n'est ni neutre, ni passif, mais il est silencieusement actif, vivant, en tension, il participe à la construction de l'être, génère des comportements, provoque des postures et des réactions. Le lieu en tant que milieu renvoie à l'ensemble des conditions qui entourent et qui influencent ceux qui s'y trouvent, les organismes aussi bien que les êtres humains. Le lieu est à la fois site, espace, étendue, environnement, contexte, il est aussi ambiance, atmosphère, climat, rythme, palpitation, odeur, son, tension, émotion, écho.

Description : Steve Gadet (maître de Conférences au Département d'Etudes Anglophones, Université des Antilles) introduit la 6e rencontre du « jeudi des livres » de la Faculté des Lettres et Sciences humaines de l'Université des Antilles qui accueille Dominique Berthet (professeur d'Art, Université des Antilles) pour la présentation de son ouvrage 40 entretiens d'artistes-Guadeloupe-Martinique (deux volumes). Jocelyn Abatucci (journaliste culturel à Martinique 1er) introduit Dominique Berthet, son parcours, ses publications et lance l'interview de l'auteur qui explique son parcours professionnel (de la peinture à l'écriture, en tant que critique d'art et qu'universitaire), les étapes de la construction de son expérience de recherche, la structuration de la recherche dans le domaine des arts à l'Université des Antilles. C'est dans ce contexte que s'inscrit sa dernière publication 40 entretiens d'artistes-Guadeloupe-Martinique. Il pense les productions artistiques comme des traces qui sont les préoccupations de l'artiste (en tant qu'individu mais aussi en tant qu'être social). Les oeuvres d'art sont l'union de l'individu et du collectif, elle parle de l'artiste mais aussi de son contexte de vie. D'où l'importance de produire des traces, de s'interroger sur les traces et d'interroger le lieu qui est un facteur déterminant de l'existence (et pas seulement dans la création), par sa prégnance, son influence.

Description : Co-fondateur de la compagnie Art & Fact, Laurent Troudart produit une libre adaptation chorégraphiée et dansée de La Nuit caribéenne et de Le Patron, deux pièces de l'écrivain Alfred Alexandre. Pour Laurent Troudart, "dans la littérature d'Alfred Alexandre les corps sont tiraillés, disloqués ou au contraire enfermés dans des lieux rêvés ou trop réels. L'espace et le temps se télescopent en permanence rejoignant les thèmes, très prégnants dans nos îles, de l'exil, du paradis perdu ou rêvé, de l'ici honni et de l'ailleurs fantasmé". Dans cette réalisation où sont intégrées musiques et voix off, des séquences des deux pièces sont entremêlées, juxtaposées, jusqu'à produire une oeuvre nouvelle. La représentation est suivie d'un échange avec Alfred Alexandre et Karine Bénac-Giroux, Maître de conférences en littérature à l'Université des Antilles.

Résumé : International audience
BACKGROUND: Thrombophilias are common disorders that increase the risk of pregnancy-associated venous thromboembolism and pregnancy loss and can also increase the risk of placenta-mediated pregnancy complications (severe pre-eclampsia, small-for-gestational-age infants, and placental abruption). We postulated that antepartum dalteparin would reduce these complications in pregnant women with thrombophilia. METHODS: In this open-label randomised trial undertaken in 36 tertiary care centres in five countries, we enrolled consenting pregnant women with thrombophilia at increased risk of venous thromboembolism or with previous placenta-mediated pregnancy complications. Eligible participants were randomly allocated in a 1:1 ratio to either antepartum prophylactic dose dalteparin (5000 international units once daily up to 20 weeks' gestation, and twice daily thereafter until at least 37 weeks' gestation) or to no antepartum dalteparin (control group). Randomisation was done by a web-based randomisation system, and was stratified by country and gestational age at randomisation day with a permuted block design (block sizes 4 and 8). At randomisation, site pharmacists (or delegates) received a randomisation number and treatment allocation (by fax and/or e-mail) from the central web randomisation system and then dispensed study drug to the local coordinator. Patients and study personnel were not masked to treatment assignment, but the outcome adjudicators were masked. The primary composite outcome was independently adjudicated severe or early-onset pre-eclampsia, small-for-gestational-age infant (birthweight <10th percentile), pregnancy loss, or venous thromboembolism. We did intention-to-treat and on-treatment analyses. This trial is registered with ClinicalTrials.gov, number NCT00967382, and with Current Controlled Trials, number ISRCTN87441504. FINDINGS: Between Feb 28, 2000, and Sept 14, 2012, 292 women consented to participate and were randomly assigned to the two groups. Three women were excluded after randomisation because of ineligibility (two in the antepartum dalteparin group and one in the control group), leaving 146 women assigned to antepartum dalteparin and 143 assigned to no antepartum dalteparin. Some patients crossed over to the other group during treatment, and therefore for on-treatment and safety analysis there were 143 patients in the dalteparin group and 141 in the no dalteparin group. Dalteparin did not reduce the incidence of the primary composite outcome in both intention-to-treat analysis (dalteparin 25/146 [17.1%; 95% CI 11.4-24.2%] vs no dalteparin 27/143 [18.9%; 95% CI 12.8-26.3%]; risk difference -1.8% [95% CI -10.6% to 7.1%)) and on-treatment analysis (dalteparin 28/143 [19.6%] vs no dalteparin 24/141 [17.0%]; risk difference +2.6% [95% CI -6.4 to 11.6%]). In safety analysis, the occurrence of major bleeding did not differ between the two groups. However, minor bleeding was more common in the dalteparin group (28/143 [19.6%]) than in the no dalteparin group (13/141 [9.2%]; risk difference 10.4%, 95% CI 2.3-18.4; p=0.01). INTERPRETATION: Antepartum prophylactic dalteparin does not reduce the occurrence of venous thromboembolism, pregnancy loss, or placenta-mediated pregnancy complications in pregnant women with thrombophilia at high risk of these complications and is associated with an increased risk of minor bleeding.

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 : 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
Fish is a rich source of essential nutrients for fetal development, but in contrast, it is also a well-known route of exposure to environmental pollutants. We assessed whether fish intake during pregnancy is associated with fetal growth and the length of gestation in a panel of European birth cohort studies. The study sample of 151,880 mother-child pairs was derived from 19 population-based European birth cohort studies. Individual data from cohorts were pooled and harmonized. Adjusted cohort-specific effect estimates were combined by using a random- and fixed-effects meta-analysis. Women who ate fish >1 time/wk during pregnancy had lower risk of preterm birth than did women who rarely ate fish (≤ 1 time/wk); the adjusted RR of fish intake >1 but <3 times/wk was 0.87 (95% CI: 0.82, 0.92), and for intake ≥ 3 times/wk, the adjusted RR was 0.89 (95% CI: 0.84, 0.96). Women with a higher intake of fish during pregnancy gave birth to neonates with a higher birth weight by 8.9 g (95% CI: 3.3, 14.6 g) for >1 but <3 times/wk and 15.2 g (95% CI: 8.9, 21.5 g) for ≥ 3 times/wk independent of gestational age. The association was greater in smokers and in overweight or obese women. Findings were consistent across cohorts. This large, international study indicates that moderate fish intake during pregnancy is associated with lower risk of preterm birth and a small but significant increase in birth weight.

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
Background: We examined the association between exposure during pregnancy to trihalomethanes, the most common water disinfection by-products, and birth outcomes in a European cohort study (Health Impacts of Long-Term Exposure to Disinfection By-Products in Drinking Water). We took into account exposure through different water uses, measures of water toxicity, and genetic susceptibility. Methods: We enrolled 14,005 mothers (2002-2010) and their children from France, Greece, Lithuania, Spain, and the UK. Information on lifestyle- and water-related activities was recorded. We ascertained residential concentrations of trihalomethanes through regulatory records and ad hoc sampling campaigns and estimated route-specific trihalomethane uptake by trimester and for whole pregnancy. We examined single nucleotide polymorphisms and copy number variants in disinfection by-product metabolizing genes in nested case-control studies. Results: Average levels of trihalomethanes ranged from around 10 μg/L to above the regulatory limits in the EU of 100 μg/L between centers. There was no association between birth weight and total trihalomethane exposure during pregnancy (β = 2.2 g in birth weight per 10 μg/L of trihalomethane, 95% confidence interval = 3.3, 7.6). Birth weight was not associated with exposure through different routes or with specific trihalomethane species. Exposure to trihalomethanes was not associated with low birth weight (odds ratio [OR] per 10 μg/L = 1.02, 95% confidence interval = 0.95, 1.10), small-for-gestational age (OR = 0.99, 0.94, 1.03) and preterm births (OR = 0.98, 0.9, 1.05). We found no gene-environment interactions for mother or child polymorphisms in relation to preterm birth or small-for-gestational age. Conclusions: In this large European study, we found no association between birth outcomes and trihalomethane exposures during pregnancy in the total population or in potentially genetically susceptible subgroups. © 2016 Wolters Kluwer Health, Inc.

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.

Résumé : International audience
PURPOSE: Multiple myeloma, a hematological malignancy generally affecting elderly people, was diagnosed at the beginning of the pregnancy of a 33-year-old woman. We carried out a literature review in order to evaluate the consequences of this cancer on pregnancy and of pregnancy on multiple myeloma, as to determine the specific follow-up required. METHODS: A systematic search for articles of interest published between 1949 and 16 November 2010 was performed in MEDLINE, SCOPUS and EMBASE, using the words "multiple myeloma" and "pregnancy". We identified 398 publications of potential interest, 20 of which were selected and included in the analysis. RESULTS: The selected articles included 26 cases. No specific risk factors were identified in pregnant women. The most common presentations were bone pain and/or anemia, as in the general population. Pregnancy seemed to have no effect on multiple myeloma progression. Most pregnancies went to term, with only two medical terminations and six cesareans performed before term, due to the severity of the cancer. No effect of the cancer or its treatment by chemotherapy during pregnancy was found in the children. CONCLUSION: Pregnancy does not seem to be contraindicated in women with multiple myeloma. Nevertheless, the management of pregnant patients with multiple myeloma is a diagnostic, therapeutic and social challenge, requiring a multidisciplinary approach and regular follow-up. Decisions should be taken based on the severity of the disease, its prognosis and maternal choice.

Résumé : International audience
BACKGROUND: Glycol ethers are present in a wide range of occupational and domestic products. Animal studies have suggested that some of them may affect ovarian function. OBJECTIVE: To study the relation between women's exposure to glycol ethers and time to pregnancy. METHODS: Urine from randomly selected women in the PELAGIE mother-child cohort who had samples collected before 19 weeks of gestation was tested to measure eight glycol ether metabolites by chromatography coupled to mass spectrometry. Time to pregnancy was collected at the beginning of the pregnancy by asking women how many months they took to conceive. Associations between metabolite levels and time to pregnancy were estimated in 519 women with complete data using discrete-time Cox proportional hazards models to adjust for potential confounders. RESULTS: Glycol ether metabolites were detected in 6% (for ethoxyacetic acid) to 93% (for phenoxyacetic and butoxyacetic acids) of urine samples. Phenoxyacetic acid was the only metabolite with a statistically significant association with longer time to pregnancy (fecundability OR 0.82; 95% CI: 0.63, 1.06 for the second and third quartile combined; fecundability OR 0.70; 95% CI: 0.52, 0.95 for a fourth-quartile (≥1.38 mg/L) vs. first-quartile concentration (<0.14 mg/L)). This association remained stable after multiple sensitivity analyses. CONCLUSION: Phenoxyacetic acid, which was present in most of the urine samples tested in our study, was associated with increased time to pregnancy. This metabolite and its main parent compound, 2-phenoxyethanol, are plausible causes of decreased fecundability, but may also be surrogates for potential co-exposures frequently present in cosmetics.

Résumé : International audience
In intrauterine pregnancies of uncertain viability with a gestational sac without a yolk sac (with a mean of three orthogonal transvaginal ultrasound measurements <25 mm), the suspected pregnancy loss should only be confirmed after a follow-up scan at least 14 days later shows no embryo with cardiac activity (Grade C). In intrauterine pregnancies of uncertain viability with an embryo <7 mm on transvaginal ultrasound, the suspected pregnancy loss should only be confirmed after a follow-up scan at least 7 days later (Grade C). In pregnancies of unknown location after transvaginal ultrasound (i.e. not visible in the uterus), a threshold of at least 3510 IU/l for the serum human chorionic gonadotrophin assay is recommended; above that level, a viable intrauterine pregnancy can be ruled out (Grade C). Postponing conception after an early miscarriage in women who want a new pregnancy is not recommended (Grade A). A work-up for women with recurrent pregnancy loss should include the following: diabetes (Grade A), antiphospholipid syndrome (Grade A), hypothyroidism with anti-thyroid peroxidase (anti-TPO) and anti-thyroglobulin (anti-Tg) antibodies (Grade A), vitamin deficiencies (B9, B12) (Grade C), hyperhomocysteinaemia (Grade C), hyperprolactinaemia (Grade B), diminished ovarian reserve (Grade C), and a uterine malformation or an acquired uterine abnormality amenable to surgical treatment (Grade C). The treatment options recommended for women with a missed early miscarriage are vacuum aspiration (Grade A) or misoprostol (Grade B); and the treatment options recommended for women with an incomplete early miscarriage are vacuum aspiration (Grade A) or expectant management (Grade A). In the absence of both chorioamnionitis and rupture of the membranes, women with a threatened late miscarriage and an open cervix, with or without protrusion of the amniotic sac into the vagina, should receive McDonald cerclage, tocolysis with indomethacin, and antibiotics (Grade C). Among women with a threatened late miscarriage and an isolated undilated shortened cervix (<25 mm on ultrasound), cerclage is only indicated for those with a history of either late miscarriage or preterm delivery (Grade A). Among women with a threatened late miscarriage, an isolated undilated shortened cervix (<25 mm on ultrasound) and no uterine contractions, daily treatment with vaginal progesterone up to 34 weeks of gestation is recommended (Grade A). Hysteroscopic section of the septum is recommended for women with a uterine septum and a history of late miscarriage (Grade C). Correction of acquired abnormalities of the uterine cavity (e.g. polyps, myomas, synechiae) is recommended after three early or late miscarriages (Grade C). Prophylactic cerclage is recommended for women with a history of three late miscarriages or preterm deliveries (Grade B). Low-dose aspirin and low-molecular-weight heparin at a preventive dose are recommended for women with obstetric antiphospholipid syndrome (Grade A).

Résumé : International audience
BACKGROUND: People in developed countries are widely exposed to low levels of organochlorine pesticides, polychlorinated biphenyls (PCBs), and polybrominated diphenyl ethers (PBDEs). Seafood is a major contributor to PCB exposure. Toxicity of those various pollutants to reproductive and endocrine functions raises questions about possible effects on fertility. We explored whether serum levels of these pollutants and seafood consumption were associated with the fertility of couples enrolled in a French birth cohort (PELAGIE). METHODS: Time-to-pregnancy was investigated in 3,421 pregnant women by asking how many months they had taken to conceive. Levels of 14 organochlorine pesticides, 12 PCBs, and 10 PBDE compounds were measured in cord blood serum from a random subcohort (n = 394). Mercury concentrations measured in maternal hair were considered as a potential coexposure. Fecundability odds ratios (ORs) were estimated from multivariate discrete-time Cox proportional hazard models. RESULTS: Shellfish consumption was associated with longer time-to-pregnancy (fecundability OR ≥twice/week vs. 0.410 µg/L vs. <0.266 µg/L, fecundability OR = 0.46 [0.32-0.66]). In multiple sensitivity analyses, reduced fecundability was most consistently associated with shellfish consumption, p,p'-DDE, total PCBs, PCB153, and PCB187. Models that simultaneously included multiple coexposure factors led to similar conclusions. CONCLUSIONS: Our findings were robust in sensitivity analyses, including analysis restricted to primiparous women. These results suggest that PCBs, p,p'-DDE, and other shellfish contaminants may impair human fertility.
