Folic and folinic acid load tests for dynamic assessments of compliance and metabolism in folate deficiency and hyperhomocysteinaemia patients unresponsive to high-dose folate replacement.

We describe the utility of 'folic and folinic acid load tests' in the investigation of a 26-year-old woman with persistently low serum folate and moderate hyperhomocysteinaemia unresponsive to folic acid supplements. Serum folate, plasma 5-methyltetrahydrofolate (5-MTHF), red cell 5-MTHF and plasma total homocysteine at baseline, 2-h, 4-h and 2- or 4-days (if applicable) post administration of a large dose of oral folic acid, or oral or parenteral folinic acid were measured. The tests confirmed non-compliance but also suggested an unsuspected possible defect in the folate pathway based on differential response to folic versus folinic acid supplements.

Built environment change for injury prevention: insights from public health professionals across public health units in Ontario, Canada.

Background: Road-related injuries and deaths are among the most significant and avoidable public health problems in Canada. Modifications to the built environment (BE) can reduce injury rates for vulnerable road users (VRUs) and other priority populations who experience disproportionate risk. This paper highlights public health professionals' experiences working in injury prevention across Ontario public health units (PHUs) navigating barriers and facilitators to BE change.

Serum Folate Concentrations in Exclusively Breastfed Preterm Infants Who Received No Supplementary Oral Folic Acid After Discharge: A Prospective Cohort Study.

Adequate folate intake is required in preterm infants for rapid growth and development, but there is little evidence to back recommendations. We aimed to assess folate status in preterm infants at discharge and in early infancy, according to exposure to folate sources, particularly in those exclusively/predominantly breastfed. A prospective, multicenter, observational cohort study was conducted in the UK, involving 45 preterm infants <33 weeks' gestational age (GA) exclusively/predominantly fed human milk when approaching NICU (Neonatal Intensive Care Unit) discharge.

(Two) Wheels on the Bus: Road User Perceptions of a Bike Bus and How This Links to Addressing Global Health Challenges.

Background: Excessive car use hampers progress toward tackling global health challenges, including climate and sustainability issues, and is linked to lower physical activity. Local communities have been developing solutions through bike buses. This paper, one of the first on bike buses, explores how a bike bus is perceived by other road and place users.
