Impact of villitis of unknown etiology and adverse acute neonatal outcomes in Eastern Ontario.

Introduction: Villitis of unknown etiology (VUE) is a histopathological lesion associated with adverse neonatal outcomes. We seek to define the obscure relationship between the severity and distribution of VUE and adverse neonatal outcomes.

Methods: A retrospective chart review was conducted of pathologic findings from singleton placentas diagnosed with VUE between 2013 and 2019.

Etiology of stillbirth in a tertiary care center: a retrospective cohort study assessing ultrasound, laboratory, and pathology investigations.

Background: Canadian stillbirth data are limited, and a significant proportion of pregnancies resulting in stillbirth have no attributable cause. The objective of this study was to characterize stillbirth case investigations and management at a tertiary care hospital in Ontario, Canada.

Methods: This was a retrospective chart review study of all cases of singleton stillbirth at The Ottawa Hospital between 1 January 2012 and 31 December 2017.

Association of distinct features of villitis of unknown etiology histopathology and fetal growth restriction diagnosis in a retrospective cohort from Eastern Ontario.

Introduction: Villitis of unknown etiology (VUE) is associated with fetal growth restriction (FGR) and adverse short-term neonatal outcomes. No investigation to date has found which VUE features are driving the association with FGR diagnosis.

Methods: A retrospective cohort study of placenta pathology specimens (2013-2017) was conducted.

Impact of COVID-19 pandemic on emergency department visits and infant health: a scoping review protocol.

Introduction: The novel SARS-CoV-2 pandemic has provided a set of unique challenges for paediatric patients requiring emergency care across the globe. Reduction in paediatric emergency department (ED) usage during the COVID-19 pandemic has been widely reported, but no studies to date have consolidated and described what ramifications these reductions may have on neonatal and infant health. This scoping review aims to characterise the impact of the COVID-19 pandemic on infant ED visits and neonatal and infant health.
