Background: Maternal hormonal contraception use has been associated with childhood leukemia risk. However, studies are few and often based on self-reported information.
Methods: Using registry data from Denmark, Norway, and Sweden, we identified 3,183,316 children (born 1996-2018) and followed them from birth until leukemia diagnosis, censoring (death, emigration, other cancer, 20th birthday) or study closure (December 31st, 2017, 2018 or 2020).
Background: The World Health Organisation (WHO) has identified a range of symptomatic manifestations to aid in the clinical diagnosis of post-COVID conditions, herein referred to as post-acute COVID-19 symptoms. We conducted an international network cohort study to estimate the burden of these symptoms in North American, European, and Asian populations.
Methods: A federated analysis was conducted including 10 databases from the United Kingdom, Netherlands, Norway, Estonia, Spain, France, South Korea, and the United States, between September 1st 2020 and latest data availability (which varied from December 31st 2021 to February 28th 2023), covering primary and secondary care, nationwide registries, and claims data, all mapped to the Observational Medical Outcomes Partnership Common Data Model (OMOP CDM).
Unlabelled: We aim to estimate the incidence rates (IRs) of SARS-CoV-2 infections stratified by disease severity and comorbidities in pediatric population and to describe the COVID-19 vaccination coverage in children with and without comorbidities. A population-based cohort study was conducted in 6 electronic healthcare records databases from Italy, Spain, and Norway. The study lasted from 1 January 2020 to the latest databases' available data in each site, i.

- Cetirizine is an antihistamine used for treating allergies and is often prescribed to breastfeeding mothers, although its effects on infants through breast milk are not well-documented.
- A population pharmacokinetic (popPK) model was created using data from a study of 35 breastfeeding women to predict cetirizine levels in breast milk and calculate the relative infant dose (RID).
- The study found a mean RID of 1.99%, indicating low exposure for infants, and suggests that cetirizine is generally safe for use during breastfeeding.
Objective: To evaluate the association between paternal metformin use and risk of congenital malformations in offspring.
Design: Population based, cross national cohort study.
Setting: Norway and Taiwan.
