    Six gel-and five water-transported Dracaena braunii shipments originating from the South coast of China were screened for exotic mosquito species during a surveillance project on exotic vectors in Belgium. In November 2013, a live Aedes (Stegomyia) albopictus larva was detected in a gel substrate. This is the first direct evidence of the importation of Ae. albopictus on gel-transported Lucky bamboo. It also confirms that the importation risk of Ae. albopictus by transport of ornamental bamboo plants remains. In addition to the registration of appropriate biocides, a structured and permanent surveillance programme is needed in Belgium to allow for the early detection of invasive mosquito species and the timely implementation of control measures.

Overview of the trapping methods used to monitor invasive mosquito species (IMS) in Belgium during the different years (and projects) and in different risk scenarios, indicating the number of traps or larval sampling visits per site and the frequency of trapping or larval sampling. TABLE S2. Aedes albopictus detections in Belgium between 2007 and 2020 at the ten points of entry (PoEs) per year including the sampling perimeter, collection and detection methods, collection (light grey) and detection (dark grey) period, control measures (X), number of individuals (total, females, males, larvae and eggs) and project. TABLE S3. Aedes japonicus detections in Belgium between 2007 and 2020 at the four points of entry (PoEs) per year including the sampling perimeter, collection and detection methods, collection (light grey) and detection (dark grey) period, the control measures (X), number of individuals (total, females, males, larvae and eggs) and project. TABLE S4. Aedes koreicus detections in Belgium between 2007 and 2020 at the two points of entry (PoEs) per year including the sampling perimeter, collection and detection methods, collection (light grey) and detection (dark grey) period, control measures (X), number of individuals (total, females, males, larvae and eggs) and project.Invasive mosquito species (IMS) and their associated mosquito-borne diseases are emerging in Europe. In Belgium, the first detection of Aedes albopictus (Skuse 1894) occurred in 2000 and of Aedes japonicus japonicus (Theobald 1901) in 2002. Early detection and control of these IMS at points of entry (PoEs) are of paramount importance to slow down any possible establishment. This article reviews the introductions and establishments recorded of three IMS in Belgium based on published (2007–2014) and unpublished (2015–2020) data collected during several surveillance projects. In total, 52 PoEs were monitored at least once for the presence of IMS between 2007 and 2020. These included used tyre and lucky bamboo import companies, airports, ports, parking lots along highways, shelters for imported cutting plants, wholesale markets, industrial areas, recycling areas, cemeteries and an allotment garden at the country border with colonised areas. In general, monitoring was performed between April and November. Mosquitoes were captured with adult and oviposition traps as well as by larval sampling. Aedes albopictus was detected at ten PoEs, Ae. japonicus at three PoEs and Aedes koreicus (Edwards 1917) at two PoEs. The latter two species have established overwintering populations. The percentage of PoEs positive for Ae. albopictus increased significantly over years. Aedes albopictus is currently entering Belgium through lucky bamboo and used tyre trade and passive ground transport, while Ae. japonicus through used tyre trade and probably passive ground transport. In Belgium, the import through passive ground transport was first recorded in 2018 and its importance seems to be growing. Belgium is currently at the invasion front of Ae. albopictus and Ae. japonicus. The surveillance and control management actions at well-known PoEs associated to long-distance introductions are more straightforward than at less-defined PoEs associated with short-distance introductions from colonised areas. These latter PoEs represent a new challenge for IMS management in Belgium in the coming years. Aedes albopictus is expected to become established in Belgium in the coming years, hence increasing the likelihood of local arbovirus transmission. The implementation of a sustainable, structured and long-term IMS management programme, integrating active and passive entomological surveillance, vector control and Public Health surveillance is therefore pivotal.The MODIRISK project (2007–2010) was funded by the Belgian Science Policy Programs; the EXOSURV project (2012) by the Federal, Flemish, Walloon and Brussels Capital region governments, the FASFC project (2013–2016) by the Federal Agency for the Safety of the Food Chain (FASFC), the MEMO and MEMO+2020 projects (2017–2020) by the Flemish, Walloon and Brussels regional governments and the Federal Public Service (FPS) Public Health, Food Chain Safety and Environment in the context of the National Environment and Health Action Plan (NEHAP) (Belgium), and the DiMoc project by the 2018–2019 BiodivERsA3 ERA-Net COFUND programme with the funding organisation FWO.

    Funder: NCI U24CA211006Abstract: The Cancer Genome Atlas (TCGA) and International Cancer Genome Consortium (ICGC) curated consensus somatic mutation calls using whole exome sequencing (WES) and whole genome sequencing (WGS), respectively. Here, as part of the ICGC/TCGA Pan-Cancer Analysis of Whole Genomes (PCAWG) Consortium, which aggregated whole genome sequencing data from 2,658 cancers across 38 tumour types, we compare WES and WGS side-by-side from 746 TCGA samples, finding that ~80% of mutations overlap in covered exonic regions. We estimate that low variant allele fraction (VAF < 15%) and clonal heterogeneity contribute up to 68% of private WGS mutations and 71% of private WES mutations. We observe that ~30% of private WGS mutations trace to mutations identified by a single variant caller in WES consensus efforts. WGS captures both ~50% more variation in exonic regions and un-observed mutations in loci with variable GC-content. Together, our analysis highlights technological divergences between two reproducible somatic variant detection efforts

    L’évaluation d’impact sur la santé peut-elle être appliquée aux programmes de candidats à l’élection présidentielle ?

    National audienceHealth impact assessment (HIA) is defined as a method by which a policy, program or project may be judged as to its potential effects on the health of a population in order to mitigate negative impacts and strengthen the positive ones. During the 2017 French presidential elections, health promotion actors decided to conduct an HIA on the political platforms of the five main candidates. The assessment of each political platform was conducted by 7 evaluators and reviewed by 35 health promotion experts. Then, a comparative analysis of the platforms was led on 3 specific topics. This HIA was conducted in accordance with the international standards of practice. Within all of the 5 political platforms, the proposals related to Environmental and energy policy, and to Agricultural policy were the ones with widely positive impacts on the determinants of health. Concerning all of the other policy proposals, their respective impacts and affected populations broadly change from one platform to another. Due to its political object, this HIA had to deal with methodological challenges such as platform instability, uncertainty over the genuine implementation of measures as well as the importance of the underlying platform values. Nonetheless, such an implementation of the HIA process on the political platforms of candidates running for an important position is interesting because it represents an opportunity to look at the platforms with fresh eyes and enriches the advocacy to take public health into account in the policy making processes and tries to operationalize the concept of health in all policies
