Neonates With In-Utero SSRI Exposure (NeoWISE): a retrospective cohort study examining the effect of newborn feeding method on newborn withdrawal.

Introduction: Up to 30% of newborns with in-utero selective serotonin reuptake inhibitor (SSRI) exposure experience withdrawal symptoms. The impact of newborn feeding method on alleviating withdrawal has not been investigated. We examined the effect of newborn feeding method (breastfeeding versus formula) among a cohort of nates ith n-utero SRI xposure (NeoWISE).

Pregnancy Outcomes in Survivors of Adolescent and Young Adult Breast Cancer: A Population-Based Cohort Study.

Objectives: To evaluate the association between adolescent and young adult (AYA) breast cancer (BC) and the adverse pregnancy outcomes of preterm birth, small for gestational age birth, cesarean delivery, and preeclampsia, and the effect of fertility treatment on this association.

Methods: Population-based cohort study with universal coverage health data for Ontario, Canada. BC was identified from the Ontario Cancer Registry.

Epidemiology and association of neighbourhood marginalisation on violent knife assaults in Ontario: a population-based case-control study.

Background: Violent knife assaults ('stabbings') are underappreciated as a source of morbidity and mortality. The two objectives of this study were to describe the epidemiology of stabbing injuries in the population of Ontario, Canada and to assess the associations between two measures of neighbourhood marginalisation-material deprivation and housing instability, and the risk of stabbing injury.

Methods: We conducted a population-based case-control study over 2004-18 using linked administrative data.

Endometriosis, Severe Maternal Morbidity, and the Effect of Infertility: Population-Based Cohort Study.

This population-based cohort evaluated the association between endometriosis and severe maternal morbidity (SMM), and the mediating effect of infertility and fertility treatment. Included were all singleton deliveries in Ontario between 2006 and 2014. Modified Poisson regression generated adjusted relative risks.

Effect of neurosurgical residency programs on neurosurgical patient outcomes in a single health care system: a cohort study.

Background: The evidence on the benefits and drawbacks of involving neurosurgical residents in the care of patients who undergo neurosurgical procedures is heterogeneous. We assessed the effect of neurosurgical residency programs on the outcomes of such patients in a large single-payer public health care system.

Methods: Ten population-based cohorts of adult patients in Ontario who received neurosurgical care from 2013 to 2017 were identified on the basis of procedural codes, and the cohorts were followed in administrative health data sources.
