Risk of preeclampsia among women living in coastal areas impacted by sargassum strandings on the French Caribbean island of Martinique.

Objective: To investigate preeclampsia risk of pregnant women living in coastal areas regularly impacted by massive sargassum strandings.

Design: Retrospective cohort study SETTINGS AND POPULATION: Pregnant women (n = 3020), seen at the University Hospital of Martinique, were included between 25/01/2016 and 31/07/2020.

Methods: Patient records were retrospectively reviewed.

Assessing Zika Virus Transmission Within Households During an Outbreak in Martinique, 2015-2016.

Since 2015, Zika virus (ZIKV) has caused large epidemics in the Americas. Households are natural targets for control interventions, but quantification of the contribution of household transmission to overall spread is needed to guide policy. We developed a modeling framework to evaluate this contribution and key epidemic features of the ZIKV epidemic in Martinique in 2015-2016 from the joint analysis of a household transmission study (n = 68 households), a study among symptomatic pregnant women (n = 281), and seroprevalence surveys of blood donors (n = 457).

Congenital Zika virus syndrome…what else? Two case reports of severe combined fetal pathologies.

Background: Zika virus (ZIKV) has recently emerged as a teratogenic infectious agent associated with severe fetal cerebral anomalies. Other microorganisms (TORCH agents) as well as genetic disorders and toxic agents may lead to similar anomalies. In case of fetal anomalies, the exact etiology might be difficult to establish, especially in ZIKV endemic countries.

Ultrasound imaging for identification of cerebral damage in congenital Zika virus syndrome: a case series.

Background: Zika virus is a novel teratogenic agent associated with cerebral anomalies. Because of the challenges associated with assessment of antenatal diagnosis and prognosis in fetuses, screening for other congenital infections mostly relies on ultrasound. We aimed to assess whether a similar approach might be adequate for Zika virus congenital syndrome provided that early markers of infection and adequate timing for screening are established.

Pregnancy Outcomes after ZIKV Infection in French Territories in the Americas.

Background: The risk of congenital neurologic defects related to Zika virus (ZIKV) infection has ranged from 6 to 42% in various reports. The aim of this study was to estimate this risk among pregnant women with symptomatic ZIKV infection in French territories in the Americas.

Methods: From March 2016 through November 2016, we enrolled in this prospective cohort study pregnant women with symptomatic ZIKV infection that was confirmed by polymerase-chain-reaction (PCR) assay.

Analysis of blood from Zika virus-infected fetuses: a prospective case series.

Background: Zika virus has spread through the Americas and the Caribbean since early 2015 and was rapidly declared a Public Health Emergency of International Concern by WHO because of the potential association with fetal anomalies. We analysed fetal and maternal fluids and tissues in fetuses with confirmed Zika virus infection prospectively monitored in Martinique, a French Caribbean island.

Methods: Since the beginning of the Zika virus outbreak in Martinique, all pregnant women undergo monthly fetal ultrasound examination surveillance.
