Paediatric intensive care admissions during the 2015-2016 Queensland human parechovirus outbreak.

Aim: The human parechovirus (HPeV) has emerged as a pathogen causing sepsis-like presentations in young infants, but there is a lack of data on HPeV presentations requiring intensive care support. We aimed to characterise the clinical presentation, disease severity, management and outcome of a population-based cohort of children with microbiologically confirmed HPeV infection requiring admission to paediatric intensive care units (PICUs) in Queensland, Australia during a recent outbreak.

Methods: This was a multicentre retrospective study of children admitted to PICU between 1 January 2015 and 31 December 2016 with confirmed HPeV infection.

Human Parechovirus 3 in Infants: Expanding Our Knowledge of Adverse Outcomes.

Background: Human parechovirus particularly genotype 3 (HPeV3) is an emerging infection affecting predominantly young infants. The potential for neurologic sequelae in a vulnerable subset is increasingly apparent. A review of 2 epidemics of human parechovirus (HpeV) infection in 2013 and in 2015 in Queensland, Australia, was undertaken, with an emphasis on identifying adverse neurodevelopmental outcome.

Genomewide evidence of environmentally mediated secondary contact of European green crab () lineages in eastern North America.

Genetic-environment associations are increasingly revealed through population genomic data and can occur through a number of processes, including secondary contact, divergent natural selection, or isolation by distance. Here, we investigate the influence of the environment, including seasonal temperature and salinity, on the population structure of the invasive European green crab () in eastern North America. Green crab populations in eastern North America are associated with two independent invasions, previously shown to consist of distinct northern and southern ecotypes, with a contact zone in southern Nova Scotia, Canada.
