Bothrops lanceolatus, commonly named 'Fer-de-Lance', is an endemic snake of the French Caribbean Island of Martinique. Envenomations by B. lanceolatus present clinical aspects characterized by systemic thrombotic syndrome and important local inflammation, involving edema and pain but limited hemorrhage. To investigate mechanisms of venom-induced inflammation, B. lanceolatus venom was characterized, its cross-reactivity with bothropic antivenom explored, its cytotoxicity on human keratinocytes and vascular cells, and the production of cytokines and chemokines were analyzed...

Adéle Broodryk, Cindy Pienaar, David Edwards, Martinique Sparks
Globally it is assumed that high-intensity activities are the general cause of fatigue experienced during a soccer match. However, little is known about the hormonal and psychological effects of fatigue due to these activities on semi-professional female soccer players. Forty-seven female players (22.0±2.7y) from a tertiary education institution volunteered for the study. Their cortisol values (saliva sample), anxiety [Spielberger State-trait anxiety inventory questionnaire (STAI)] and mood scores [Incredible Short Profile of Mood states questionnaire (ISP)] were taken an hour and immediately prior to, and 15min after an anaerobic fatiguing test (AFT)...

Understanding the spatio-temporal dynamics of endemic infections is of critical importance for a deeper understanding of pathogen transmission, and for the design of more efficient public health strategies. However, very few studies in this domain have focused on emerging infections, generating a gap of knowledge that hampers epidemiological response planning. Here, we analyze the case of a Chikungunya outbreak that occurred in Martinique in 2014. Using time series estimates from a network of sentinel practitioners covering the entire island, we first analyze the spatio-temporal dynamics and show that the largest city has served as the epicenter of this epidemic...

The Guillain-Barré syndrome (GBS) has been reported as a possible complication of acute chikungunya infection. The chikungunya epidemics, which occurred in Martinique and Guadeloupe in 2014, affected 308,000 people in these two islands. GBS occurred during or immediately after acute chikungunya infection in 13 patients (10 men, three women; mean age: 61 years). Median time from acute chikungunya to GBS onset was 9 days. Twelve patients were treated with intravenous polyvalent immunoglobulins, nine of whom improved within 7 days...

We conducted an observational study to describe the characteristics of infective endocarditis (IE) in French West Indies (FWI) and to identify variables associated with in-hospital case fatality. The records of the patients admitted for IE to the University Hospital of Martinique between 2000 and 2012 were collected using an electronic case report form. Only Duke-Li definite cases were considered for this analysis. Variables associated with in-hospital mortality were tested using univariate logistic regression analysis...

Zika virus (ZIKV) has recently emerged into new areas in the Americas and Asia, causing an epidemic characterized by severe congenital infections. While ZIKV infection is usually asymptomatic or causes mild symptoms, it has now caused a high rate of foetal brain and ocular abnormalities. The underlying reasons for the varying severity of disease outcomes is poorly understood. In this study, we compared the infectivity and replication of three disease-associated Zika viruses of Asian lineage, as well as the prototypic ZIKV strain from Africa...

Since 1972, the French departments of Guadeloupe and Martinique have intensively used organochlorinated pesticides such as chlordecone (CLD) and hexachlorocyclohexane (HCH) isomers to prevent the proliferation of banana weevil (Cosmopolite sordidus). These molecules are stable in the environment, leading to a continuous contamination of soils, water, and food chain in the banana-producing areas. In these polluted areas, water treatment plants are equipped with activated carbon (AC) filters. In order to improve treatment of CLD-contaminated waters by AC, CLD adsorption and desorption kinetic studies are carried out using different ACs produced from sugar cane bagasse as adsorbents and subsequent CLD degradation is performed using reduced vitamin B12 (VB12)...

Background: African American (AA) men battling multiple morbidities are tasked with managing the components of each condition and are at greater risk for adverse outcomes such as poor health-related quality of life (QOL), disability, and higher mortality rates. Method: Baseline data for AA men from the University of Alabama at Birmingham Study of Aging were utilized. Factor analysis was used to categorize medical conditions and create factor scores. Covariate-adjusted regression models assessed the relationships between categories of conditions and physical and mental health-related QOL as assessed by the SF-12...

BACKGROUND: The Caribbean ranks seventh among world regions most affected by cervical cancer. Social health inequalities, such as differences in access to screening services, engender disparities in incidence and mortality between low- and middle-income countries and industrialized countries. The French National Cancer Plan 2014-2019 focuses on reducing inequalities in cervical cancer. OBJECTIVE: The aim of this study was to describe the geographical distribution and overall survival of cervical cancer, based on data from a population-based cancer registry in Martinique (French West-Indies)...

BACKGROUND: Leptospirosis is a potentially life-threatening but curable zoonosis whose prognosis depends on accurate and timely diagnosis. Because of its non-specific clinical presentation, laboratory testing is essential to confirm the diagnosis. Here, we aimed to assess the performance of two enzyme-linked immunosorbent assays (ELISAs) (ELISA Serion and ELISA-Hb Pasteur) and one immunodot (GenBio) using quantitative PCR (qPCR) as gold standard, instead of the traditional microscopic agglutination test, for the diagnosis of acute leptospirosis in an endemic area...

The understanding of factors affecting pesticide transfers to catchment outlet is still at a very early stage in tropical context, and especially on tropical volcanic context. We performed on-farm pesticide use surveys during 87 weeks and monitored pesticides in water weekly during 67 weeks at the outlet of a small catchment in Martinique. We identified three types of pollution. First, we showed long-term chronic pollution by chlordecone, diuron and metolachlor resulting from horticultural practices applied 5-20 years ago (quantification frequency higher than 80%)...

BACKGROUND: Lung cancer is the leading cause of cancer-related death worldwide. Shorter survival has been repeatedly reported for patients of African ancestry. Multivariate analysis demonstrated that this gap could be a consequence of socio-economic disparities instead of genetic specificities. However, those results were obtained in a pre-targeted therapies era and the effect of tyrosine kinase inhibitors targeting EGFR are not known in this population. OBJECTIVE: In this French West Indies study, we report overall survival (OS) in a frequently mutated population treated for lung adenocarcinoma within an equal-access healthcare system...

Bacterial wilt caused by Ralstonia solanacearum is one of the world's most important soil-borne plant diseases. In Martinique, French West Indies, a highly virulent new pathogenic variant of this bacterium (phylotype IIB/4NPB) severely impacts tomato production. Here we report on the effect of R. solanacearum CFBP 6783, classified in phytotype IIB/4NPB, on tomato plantlets grown under strict in vitro culture conditions in the presence or absence of the arbuscular mycorrhizal fungus Rhizophagus irregularis MUCL 41833...

Ocean thermal energy conversion (OTEC) is a form of power generation, which exploits the temperature difference between warm surface seawater and cold deep seawater. Suitable conditions for OTEC occur in deep warm seas, especially the Caribbean, the Red Sea and parts of the Indo-Pacific Ocean. The continuous power provided by this renewable power source makes a useful contribution to a renewable energy mix because of the intermittence of the other major renewable power sources, i.e. solar or wind power. Industrial-scale OTEC power plants have simply not been built...

Hepatitis B virus (HBV) genotypes show a distinctive geographical distribution worldwide and genotypes A, D and E are the most frequently found in Africa. There are only limited studies on HBV genotype distribution in Democratic Republic of Congo (DRC), all done in the western part showing a vast majority of genotype E. In our study, HBV strains from South Kivu, an eastern province of the DRC, were analysed. Sequencing of 41 serum samples from HBV infected patients revealed strains of genotype A in 40/41 (97...

The kelp forest of the Pacific temperate rocky marine coastline of Monterey Bay in California is a dominant habitat for large brown macro-algae in the order of Laminariales. It is probably one of the most species-rich, structurally complex and productive ecosystems in temperate waters and well-studied in terms of trophic ecology. However, still little is known about the microorganisms thriving in this habitat. A growing body of evidence suggests that bacteria associated with macro-algae represent a huge and largely untapped resource of natural products with chemical structures that have been optimized by evolution for biological and ecological purposes...

INTRODUCTION: Some studies suggest that thrombotic thrombocytopenic purpura (TTP) occurs more often in African Americans. However there is low evidence for this in the literature. The aim of our study was to describe the clinical and biological characteristics of TTP in the Afro-Caribbean population of Martinique. METHODS: We retrospectively analysed all patients with TTP diagnosed at the Fort-de-France hospital between 2008, January 1st and 2015, December 31st...

INTRODUCTION: Despite a similar health insurance coverage and access to contraception, Martinique F.W.I. has a higher rate of abortion than continental France (25.6 versus 15.3 per thousand respectively). The reasons are still largely unknown. A different contraceptive pattern, a lower use of emergency contraception in Martinique may be involved. We sought to explore the contraceptive pattern, to evaluate the use of emergency contraception and the reasons leading to an unwanted pregnancy among women seeking for an abortion...
