Alveolar echinococcosis (AE)-caused by the cestode Echinococcus multilocularis-is a severe zoonotic disease found in temperate and arctic regions of the northern hemisphere. Even though the transmission patterns observed in different geographical areas are heterogeneous, the nuclear and mitochondrial targets usually used for the genotyping of E. multilocularis have shown only a marked genetic homogeneity in this species. We used microsatellite sequences, because of their high typing resolution, to explore the genetic diversity of E. multilocularis. Four microsatellite targets (EmsJ, EmsK, and EmsB, which were designed in our laboratory, and NAK1, selected from the literature) were tested on a panel of 76 E. multilocularis samples (larval and adult stages) obtained from Alaska, Canada, Europe, and Asia. Genetic diversity for each target was assessed by size polymorphism analysis. With the EmsJ and EmsK targets, two alleles were found for each locus, yielding two and three genotypes, respectively, discriminating European isolates from the other groups. With NAK1, five alleles were found, yielding seven genotypes, including those specific to Tibetan and Alaskan isolates. The EmsB target, a tandem repeated multilocus microsatellite, found 17 alleles showing a complex pattern. Hierarchical clustering analyses were performed with the EmsB findings, and 29 genotypes were identified. Due to its higher genetic polymorphism, EmsB exhibited a higher discriminatory power than the other targets. The complex EmsB pattern was able to discriminate isolates on a regional and sectoral level, while avoiding overdistinction. EmsB will be used to assess the putative emergence of E. multilocularis in Europe.

This study aimed to evaluate the efficacy of a newly implemented Child Protection Alert System (CPAS) that utilizes triggering diagnoses to identify children who have been confirmed/strongly suspected as maltreated. We retrospectively reviewed electronic health records (EHRs) of 666 patients evaluated by our institution’s child protection team between 2009 and 2014. We examined each EHR for the presence of a pop-up alert, a persistent text-based visual alert, and diagnoses denoting child maltreatment. Diagnostic accuracy of the CPAS for child maltreatment identification was assessed. Of 323 patients for whom child maltreatment was confirmed/strongly suspected, 21.7% (70/323) had a qualifying longitudinal diagnosis listed. The pop-up alert fired in 14% of cases (45/323) with a sensitivity and specificity of 13.9% (95% CI [10.4%, 18.2%]) and 100% (95% CI [98.9%, 100.0%]), respectively. The text-based visual alert displayed in 44 of 45 cases. The CPAS is a novel simple way to support clinical decision-making to identify and protect children at risk of (re)abuse. This study highlights multiple barriers that must be overcome to effectively design and implement a CPAS to protect at-risk children.
