Synthesis and characterization of isotopically barcoded nickel, molybdenum, and tungsten taggants for intentional nuclear forensics.

Intentional nuclear forensics is a concept wherein the deliberate addition of benign and persistent material signatures to nuclear material can be used to reduce the time between the discovery of material outside of regulatory control and determination of its original provenance. One concept within intentional nuclear forensics involves the use of perturbed stable isotopes to generate unique isotope ratio "barcodes" to encode information (e.g.

Transition experiences of adolescents and young adults working with a patient navigator.

Introduction: The transition from pediatric to adult care poses challenges for adolescents and young adults (AYA) with chronic conditions and their caregivers. A patient navigator (PN) intervention may mitigate transition-related barriers.

Methods: A qualitative study was conducted within a pragmatic randomized controlled trial.

A national cross-sectional survey of health literacy of caregivers attending Canadian pediatric emergency departments.

Background: Health literacy assessment is key to better meeting family needs and developing informed strategies to promote positive health outcomes for children. The objective of this study was to describe the health literacy of caregivers who use Canadian pediatric emergency departments and relate it to demographic and visit-specific variables.

Methods: This study utilized a descriptive, cross-sectional survey design with medical record review.

Engaging Red River Métis families in Manitoba in the development of child health resources - findings from a qualitative study.

Background: Most research that includes Red River Métis tends to be pan-Indigenous. Grouping Métis with First Nations and Inuit can diminish their unique and diverse experiences, as well as distinctions-based approaches. Taking a step toward addressing this problem, the Manitoba Métis Federation (MMF; the national government of the Red River Métis) invited researchers within the Canadian network Translating Emergency Knowledge for Kids to partner in this research, which focuses on understanding engagement strategies that can help expose Red River Métis parents to child health research opportunities and build trust and transparency amongst research partners and participants.

Advancing Systemic Toxicity Risk Assessment: Evaluation of a NAM-based Toolbox Approach.

For many years, a method that allowed systemic toxicity safety assessments to be conducted without generating new animal test data, seemed out of reach. However, several different research groups and regulatory authorities are beginning to use a variety of in silico, in chemico and in vitro techniques to inform safety decisions. To manage this transition to animal-free safety assessments responsibly, it is important to ensure that the level of protection offered by a safety assessment based on new approach methodologies (NAMs), is at least as high as that provided by a safety assessment based on traditional animal studies.
