    BACKGROUND: Histoplasmosis is a fungal disease caused by Histoplasma capsulatum. Histoplasma capsulatum var capsulatum is found in Martinique. Cluster cases following working in deserted house, have been described in Martinique. Cases of acute pulmonary histoplasmosis have been described in immunosuppressed individuals, or in case of substantial exposure to reservoirs of Histoplasma capsulatum; however, cases of acute histoplasmosis are rare in immunocompetent individuals.
    METHODS: We report a series of 4 cases of sporadic acute pulmonary histoplasmosis in immunocompetent subjects. Investigation revealed definite exposure in one patient and 3 cases with potential exposure. The diagnosis was microbiological and histological in 3 patients and histological in one patient. All subjects had positive serology to histoplasmosis. Pulmonary involvement was in the form of nodules and micronodules in 3 cases and ground glass lesions in one case. Patients were treated with itraconazole for 3 months and all had a favourable outcome.
    CONCLUSIONS: We report a series of 4 cases of acute pulmonary histoplasmosis in immunocompetent individuals, occurring in a context where exposure was uncertain. This raises the problem of occult exposure in the Caribbean. Interventions to raise awareness and encourage caution are warranted targeting the population of the French West Indies and French Guiana.

    本研究旨在评估(1)LFS提供的生态系统服务(ES)和(2)猪的本地(克里奥尔语)和外来品种之间的差异ES,牛和山羊.ES被定义为人类从LFS中获得的益处。它们被总结在12项ES指标中,这些指标涵盖了与供应相关的服务,生态和社会文化方面和领土活力。分析了涵盖瓜德罗普岛五个农业生态区的总共106个LFS单元。从调查中创建了每个物种的LFS的功能类型。测试了品种对ES指标的影响。结果表明,40只猪LFS单位被分成3个簇,根据供应ES(簇1)在ES中区分,对社区的文化使用和销售(集群2)和猪肉自我消费(集群3)。57个有牛的农场的类型区分了4个集群,这些集群在自我消费中提供了不同的ES(集群1),生态ES(集群2),赛牛或草牛的社会文化ES(第3组)和与领土活力相关的ES(第4组)。66个山羊LFS单元被分为3个关于自我消费的ES不同的集群(集群1),文化方面(集群2)和供应ES(集群3)。我们的研究强调,ES指标不依赖于品种(P>0.10),而是依赖于畜牧业系统。ES更多地依赖于饲养管理,而不是品种类型,到现在为止,瓜德罗普岛没有规格来区分品种之间的管理。
    The present study aims to assess (1) the ecosystem services (ES) provided by LFS and (2) the differential ES between local (Creole) and exotic breeds from pig, cattle and goat. The ES are defined as the benefits that humans derive from LFS. They were summarized in 12 ES indicators that cover services related to provisioning, ecological and socio-cultural aspects and territorial vitality. A total of 106 LFS units that covers the five agroecological zones of Guadeloupe were analysed. Functional typologies of LFS per species were created from surveys. The effect of breed on the ES indicators was tested. Results showed that the 40 pig LFS units were separated into 3 clusters that were differentiated in ES according to provisioning ES (cluster 1), cultural use and sale to the neighborhood (cluster 2) and pork self-consumption (cluster 3). The typology of the 57 farms with cattle distinguished 4 clusters with differences in ES provided in self-consumption (cluster1), ecological ES (cluster 2), socio-cultural ES for racing or draught oxen (cluster 3) and ES associated with territory vitality (cluster 4). The 66 goat LFS units were classified into 3 clusters different in ES concerning self-consumption (cluster 1), cultural aspects (cluster 2) and provisioning ES (cluster 3). Our study highlights that ES indicators are not breed dependent (P > 0.10) but rather livestock farming system dependent. The ES rely more on the rearing management than on the breed type, and up to now, there are no specifications in Guadeloupe to differentiate management between breeds.

    背景:陆地扁平虫Amaga外籍人士Jones&Sterrer,从1963年和1988年在百慕大收集的两个标本中描述了2005年(大地科),此后没有记录。
    方法:在公民科学项目的基础上,我们收到了现场的观察,马提尼克岛和瓜德罗普岛的非专业人士和当地科学家的照片和标本。我们对来自两个岛屿的(COI)标本进行了条形码化,并研究了一个标本的生殖器官的组织学。基于下一代测序,我们从污染的DNA中获得了A.expatria的完整有丝分裂基因组和一些有关其猎物的信息。
    结果:我们在加勒比海弧的两个法国岛屿中添加了2006年至2019年的记录,瓜德罗普岛(六项记录)和马提尼克岛(14项记录),根据从公民科学和标本检查获得的照片。对马提尼克岛的标本进行了交配器官的组织学研究,并对COI基因进行了条形码化;它的解剖结构与整型相似,从而确认物种鉴定。马提尼克岛和瓜德罗普岛的几个标本的COI基因相同,与最接近的物种相差10%以上;因此,通过标准分子条形码技术可以对物种进行分子表征。有丝分裂基因组长度为14,962bp,包含12个蛋白质编码基因,两个rRNA基因和22个tRNA基因;对于两个蛋白质基因,不可能确定起始密码子。将有丝分裂基因组与来自地平面的少数可用的有丝分裂基因组进行了比较,最相似的是奥巴马·南加拉,一种来自南美洲的物种。对消化系统中污染DNA的分析表明,外籍人士捕食陆生软体动物,该领域的公民科学观察表明,猎物包括软体动物和earth;因此,该物种可能对加勒比海土壤动物的生物多样性构成威胁。
    BACKGROUND: The land flatworm Amaga expatria Jones & Sterrer, 2005 (Geoplanidae) was described from two specimens collected in Bermuda in 1963 and 1988 and not recorded since.
    METHODS: On the basis of a citizen science project, we received observations in the field, photographs and specimens from non-professionals and local scientists in Martinique and Guadeloupe. We barcoded (COI) specimens from both islands and studied the histology of the reproductive organs of one specimen. Based on Next Generation Sequencing, we obtained the complete mitogenome of A. expatria and some information on its prey from contaminating DNA.
    RESULTS: We add records from 2006 to 2019 in two French islands of the Caribbean arc, Guadeloupe (six records) and Martinique (14 records), based on photographs obtained from citizen science and specimens examined. A specimen from Martinique was studied for histology of the copulatory organs and barcoded for the COI gene; its anatomy was similar to the holotype, therefore confirming species identification. The COI gene was identical for several specimens from Martinique and Guadeloupe and differed from the closest species by more than 10%; molecular characterisation of the species is thus possible by standard molecular barcoding techniques. The mitogenome is 14,962 bp in length and contains 12 protein coding genes, two rRNA genes and 22 tRNA genes; for two protein genes it was not possible to determine the start codon. The mitogenome was compared with the few available mitogenomes from geoplanids and the most similar was Obama nungara, a species from South America. An analysis of contaminating DNA in the digestive system suggests that A. expatria preys on terrestrial molluscs, and citizen science observations in the field suggest that prey include molluscs and earthworms; the species thus could be a threat to biodiversity of soil animals in the Caribbean.

    This paper presents a study of the visual properties of natural and Amerindian cultural landscapes in late pre-colonial East-Guadeloupe and of how these visual properties affected social interactions. Through a review of descriptive and formal visibility studies in Caribbean archaeology, it reveals that the ability of visual properties to affect past human behaviour is frequently evoked but the more complex of these hypotheses are rarely studied formally. To explore such complex hypotheses, the current study applies a range of techniques: total viewsheds, cumulative viewsheds, visual neighbourhood configurations and visibility networks. Experiments were performed to explore the control of seascapes, the functioning of hypothetical smoke signalling networks, the correlation of these visual properties with stylistic similarities of material culture found at sites and the change of visual properties over time. The results of these experiments suggest that only few sites in Eastern Guadeloupe are located in areas that are particularly suitable to visually control possible sea routes for short- and long-distance exchange; that visual control over sea areas was not a factor of importance for the existence of micro-style areas; that during the early phase of the Late Ceramic Age networks per landmass are connected and dense and that they incorporate all sites, a structure that would allow hypothetical smoke signalling networks; and that the visual properties of locations of the late sites Morne Souffleur and Morne Cybèle-1 were not ideal for defensive purposes. These results led us to propose a multi-scalar hypothesis for how lines of sight between settlements in the Lesser Antilles could have structured past human behaviour: short-distance visibility networks represent the structuring of navigation and communication within landmasses, whereas the landmasses themselves served as focal points for regional navigation and interaction. We conclude by emphasising that since our archaeological theories about visual properties usually take a multi-scalar landscape perspective, there is a need for this perspective to be reflected in our formal visibility methods as is made possible by the methods used in this paper.

    This paper presents a study on ground-level ozone (O3), nitrogen oxides (NOx = NO + NO2) concentrations, and their variabilities in the ambient air of three sites of a tropical archipelago that is moderately urbanized. Statistical analysis was performed on a quite complete (>80%) set of 5 years of measurements (2008-2012). There are few studies on those pollutants and their seasonal behavior in the Caribbean area, where pollution level and cities configuration are different from megacities. Analyses are focused on pollutant variations at the scale of the day, the week, and the seasons, using hourly data. The observations show that NOx concentrations are more elevated during the wet season, whereas O3 concentrations are higher in the dry season. Amplitudes of ozone cycles are strongly influenced by meteorological conditions (temperature, global radiation, and wind speed) and prevailing levels of NOx. An ozone weekend effect is detected with the highest amplitude in the city, where anthropogenic activity is the lowest during the weekend. Due to the nature and the origin of pollutants, NOx shows higher variability than O3 in the time series. Our results evince the need for continuous measurements of volatile organic compounds (VOCs) in order to better quantify their contribution in O3 formation in an insular context where numerous natural sources have been identified. Implications: Statistical analyses of observed NOx and O3 concentrations for 5 years for a typical low industrialized site of the Caribbean area have been done. Air quality for those components is correct based on the standards of the World Health Orgaization, pollutant source spatial distributions, and level of industrialization. Observations show the same patterns as in megacities but also a strong impact of weather conditions and road traffic. Behaviors of O3 cannot be fully explained without VOCs monitoring. Localization and type of AQS should be reconsidered to improve the accuracy of concentrations of the pollutant and better understand their behaviors.

    Community-acquired bacterial meningitis due to Klebsiella pneumoniae has mainly been described in Southeast Asia and has a poor prognosis. Severe invasive infections caused by K. pneumoniae, including meningitis, are often due to hypervirulent strains (hvKP), which are characterized by capsular serotypes K1 and K2, a gene responsible for hypermucoviscosity, and the cluster for synthesis of the siderophore aerobactin.
    A 55 year old man with a history of essential hypertension, benign prostate hyperplasia, hyperlipidemia, obstructive sleep apnea, and chronic alcoholism was admitted for meningitis due to Klebsiella pneumoniae with a wild-type susceptibility profile. Its genomic features were consistent with a capsular K2 strain belonging to clonal group 86 (CG86) displaying the large virulence of Klebsiella plasmid (pLVPK) with heavy metal resistance gene clusters, aerobactin, rmpA.
    This is the first case of community-acquired meningitis caused by a hypervirulent strain of hvKP ever reported in the Caribbean.

    Dengue is an emerging, rapidly expanding disease, whose clinical and biological manifestations vary. Kidney injury is not usual but can be severe, and it is most often associated with dengue hemorrhagic fever or shock. Guadeloupe, which is located in an endemic area, experienced an epidemic from 2013 to 2014. During this outbreak, a case of renal failure during dengue was observed in a 10-year-old child. No evidence of dengue hemorrhagic fever or shock syndrome was found. The clinical and biological course improved with symptomatic treatment. The association of acute renal failure with hemolytic anemia suggested a diagnosis of hemolytic uremic syndrome. However, this could not be confirmed in the absence of thrombocytopenia and cytopathologic evidence. This case illustrates the diversity of clinical presentations of dengue, and the possibility of severe renal impairment unrelated to the usual factors encountered in dengue.

    OBJECTIVE: Characterize a NDM-1 producing K. pneumoniae isolate recovered from a patient hospitalized in Guadeloupe, French West Indies, after its transfer from Cuba
    METHODS: Antibiotic susceptibilities were determined by the disk diffusion method, and E-test. Carbapenemase production was assessed using the Carba NP test. Antibiotic resistance determinants and their surrounding structures were characterized by PCR mapping and DNA sequencing. Transfer of the β-lactam resistance marker was attempted by liquid mating-out assays
    RESULTS: Here we reported the first NDM-1 producing enterobacterial isolate recovered from Caribbean islands. This K. pneumoniae isolate belongs to a new sequence type (ST1649). The blaNDM-1 gene together with the aacA4 gene were carried on a self conjugative IncR plasmid of c.a. 80kb.
    CONCLUSIONS: This study describes the first identification of a NDM-1 producer in Caribbean islands. The uncommon incompatibility group of the blaNDM-1 carrying plasmid and the uncommon ST type of the K. pneumoniae strain suggest a possible local emergence of NDM producers.

    背景:长期暴露于具有激素特性的持久性污染物(内分泌干扰化学物质;EDC)可能会导致前列腺癌(PCa)的风险。然而,流行病学证据仍然有限。
    目的:我们研究了PCa与普遍分布的污染物的血浆浓度之间的关系,特别是p,对二氯二苯基二氯乙烯(DDE)和非二恶英样多氯联苯同类物153(PCB-153)。
    方法:我们在瓜德罗普岛(法属西印度群岛)评估了576例新诊断为PCa的男性(治疗前)和655例对照。根据病例对照状态分析暴露情况。通过无条件逻辑回归分析评估关联,控制混杂因素。缺少的数据通过多重插补处理。
    结果:我们估计DDE和PCa之间存在显著正相关[调整后比值比(OR)=1.53;95%CI:1.02,2.30最低五分之一的暴露;p趋势=0.01]。PCB-153与PCa呈负相关(OR=0.30;95%CI:0.19,0.47,最高暴露值的最低五分之一;p趋势<0.001)。此外,PCB-153与低级PCa的相关性比与高级PCa的相关性更强。
    结论:PCa与DDE和PCB-153的关联方向相反。这可能反映了这些EDC作用机制的差异;尽管我们的发现需要在其他人群中复制,它们与EDC对人类健康的复杂影响一致。
    BACKGROUND: Long-term exposure to persistent pollutants with hormonal properties (endocrine-disrupting chemicals; EDCs) may contribute to the risk of prostate cancer (PCa). However, epidemiological evidence remains limited.
    OBJECTIVE: We investigated the relationship between PCa and plasma concentrations of universally widespread pollutants, in particular p,p\'-dichlorodiphenyl dichloroethene (DDE) and the non-dioxin-like polychlorinated biphenyl congener 153 (PCB-153).
    METHODS: We evaluated 576 men with newly diagnosed PCa (before treatment) and 655 controls in Guadeloupe (French West Indies). Exposure was analyzed according to case-control status. Associations were assessed by unconditional logistic regression analysis, controlling for confounding factors. Missing data were handled by multiple imputation.
    RESULTS: We estimated a significant positive association between DDE and PCa [adjusted odds ratio (OR) = 1.53; 95% CI: 1.02, 2.30 for the highest vs. lowest quintile of exposure; p trend = 0.01]. PCB-153 was inversely associated with PCa (OR = 0.30; 95% CI: 0.19, 0.47 for the highest vs. lowest quintile of exposure values; p trend < 0.001). Also, PCB-153 was more strongly associated with low-grade than with high-grade PCa.
    CONCLUSIONS: Associations of PCa with DDE and PCB-153 were in opposite directions. This may reflect differences in the mechanisms of action of these EDCs; and although our findings need to be replicated in other populations, they are consistent with complex effects of EDCs on human health.

  • 文章类型: Comparative Study
    OBJECTIVE: The objective of this retrospective study is to compare two types of antimicrobial management used to treat premature rupture of membranes in pregnancy. This study evaluates both duration and the type of antibiotic therapy used for treatment.
    METHODS: The antimicrobials used to treat premature rupture of membranes include a first generation cephalosporin in one group and amoxicillin in the other group. Cephalosporin was used over a 7-day period to treat 38 cases, whereas amoxicillin was used through delivery in 52 cases. Emergence of multidrug-resistant Gram negative bacteria (GNB) on maternal of neonatal sampling was the primary outcome.
    RESULTS: Emergence of antibiotic resistant GNB can be seen under both antibiotic regimens and appears to be linked to the duration of latency, and to duration of antibiotic treatment. Other outcomes (duration of latency period, gestational age at delivery, maternal and neonatal complications) were similar in both groups.
    CONCLUSIONS: Antibiotic treatment in PPROM favors a selection of GNB. This emergence is positively linked with the duration of latency between rupture of membranes and delivery and with the length of antibiotic administration. The extension of antibiotherapy does not alter other maternal or neonatal parameters.
