Article Synopsis
- - The study investigates how socioeconomic status (SES) and healthcare access affect the diagnosis and outcomes of childhood acute lymphoblastic leukemia (ALL) in Canada, examining data from 2001 to 2019 for children under 15 years old.
- - Researchers analyzed the connections between neighborhood income levels and distance to treatment centers in relation to high-risk features at diagnosis, treatment timeliness, and survival rates using multivariable analyses and Cox proportional hazards models.
- - Results show no significant link between income or distance from treatment centers and most outcomes; however, children in higher income brackets experienced better event-free survival, while distance to treatment was associated with greater incidence of central nervous system disease at diagnosis and differences in treatment timelines.
Introduction: From the advancement of treatment of pediatric cancer diagnosis, the five-year survival rate has increased significantly. However, the adverse consequence of improved survival rate is the second malignant neoplasm. Although previous studies provided information on the incidence and risk of SMN in long term survivors of childhood cancer, there is still scarce information known for short term (< 5 years) prognosis.

Mumps surveillance, including monitoring of the mumps virus genotype associated with disease activity, is important to document baseline activity and to advance further research into vaccine effectiveness. Here we describe a detailed analysis of mumps cases that have been detected in Canada from 2002 to 2020, with a focus on the mumps molecular epidemiology.

Article Synopsis
- The study conducted a systematic review to evaluate the effectiveness of algorithm methods used in administrative databases for identifying cases of autism spectrum disorder (ASD), attention-deficit/hyperactivity disorder (ADHD), and fetal alcohol spectrum disorder (FASD).
- The researchers searched multiple databases for relevant studies and ultimately included 14 articles for analysis, noting that no studies specifically addressed FASD.
- Findings indicated that while algorithms incorporating multiple data sources improved the accuracy of ASD identification, particularly using physician claims data, there was insufficient information to determine the same for ADHD.
This article provides a summary of the epidemiology of multisystem inflammatory syndrome in children (MIS-C) cases reported nationally in Canada by provincial and territorial health authorities. Multisystem inflammatory syndrome in children is a post-viral inflammatory syndrome that temporally follows coronavirus disease 2019 (COVID-19). Symptoms may include fever, abdominal pain, vomiting, diarrhea, skin rash and other signs of inflammation.

We evaluated the long-term safety of exposure to Tdap vaccination during pregnancy.
Methods: Population-based retrospective cohort study conducted in Ontario, Canada using multiple linked province-wide health administrative databases.

Background: In February 2018, Canada's National Advisory Committee on Immunization recommended maternal vaccination with tetanus-diphtheria-acellular pertussis (Tdap) vaccine during pregnancy to prevent severe pertussis infection in young infants. This study assessed the relation between maternal Tdap vaccination and obstetric and perinatal outcomes in Ontario.
Methods: We performed a population-based cohort study of all births from April 2012 to March 2017 using multiple linked health administrative databases.
