[SARS-Cov-2 vaccine's acceptance among pregnant women-A cross-sectional survey]. / Acceptabilité du vaccin-Sars CoV-2 chez les femmes enceintes, une enquête transversale par questionnaire.

OBJECTIVE: SARS-CoV-2 is more likely to cause severe cases in pregnant women. They were part of the priority groups since April 2021 to benefit from SARS-CoV-2 vaccination before its extent to general population. This contribution aims to evaluate, in the postpartum period, the achievement of COVID-19 vaccination and factors associated in women during their pregnancy. MATERIAL AND METHOD: Multicenter cross-sectional survey study conducted from September to December 2021 with online self-questionnaire. All postpartum patients hospitalized in one of the 6 participating maternity hospitals were invited to answer. The questionnaire asked patients about their demographic characteristics, vaccination modalities, vaccine tolerance, and their general perception of vaccination. RESULTS: Of the 371 women who responded, the vaccination rate was 65.7% (IC95% [60.8-70.4]), whom 98.8% entirely during pregnancy. Associated factors with vaccination during pregnancy were older age, higher socio-professional category, and prior information provided by health professionals. Factors that appear to motivate vaccination were personal protection and protection of the newborn. Finally, main factors negatively influencing the vaccination process were the fear of vaccine side effects and the negative perception of vaccines in general. DISCUSSION: Acceptability and information about the vaccine by health professionals is in constant improvement. Information campaigns should be continued to improve the acceptability of vaccination, in light of the accumulating data.

Potential transfer of aquatic organisms via ballast water with a particular focus on harmful and non-indigenous species: A survey from Adriatic ports.

Ballast water discharges may cause negative impacts to aquatic ecosystems, human health and economic activities by the introduction of potentially harmful species. Fifty untreated ballast water tanks, ten in each port, were sampled in four Adriatic Italian ports and one Slovenian port. Salinity, temperature and fluorescence were measured on board. Faecal indicator bacteria (FIB), phyto- and zooplankton were qualitatively and quantitatively determined to identify the species assemblage arriving in ballast water. FIB exceeded the convention standard limits in 12% of the sampled tanks. Vibrio cholerae was not detected. The number of viable organisms in the size groups (minimum dimension) <50 and ≥10 µm and ≥50 µm resulted above the abundances required from the Ballast Water Management Convention in 55 and 86% of the samples, respectively. This is not surprising as unmanaged ballast waters were sampled. Some potentially toxic and non-indigenous species were observed in both phyto- and zooplankton assemblages.
