Preventing symptomatic vitamin D deficiency and rickets among Indigenous infants and children in Canada
Bibliographic record
Abstract
Vitamin D deficiency (VitDD) rickets and other manifestations of severe VitDD, such as cardiomyopathy and hypocalcemic seizures, continue to be diagnosed in Canada. Breastfed Indigenous infants, particularly those living in northern communities, are disproportionately impacted, although formula-fed infants are not exempt in cases where the mother's vitamin D status is critically low. This statement deals with the prevention of rickets and hypocalcemia due to VitDD for Indigenous children, and revises an earlier document from the Canadian Paediatric Society. An assessment of the risk for VitDD is recommended for each maternal-infant dyad because of the link between maternal and infant VitDD. Along with supports for enhanced adherence, additional VitD supplementation is recommended for prenatal women and infants deemed at high risk and, in certain situations, intermittent higher dose supplementation may be required. Food insecurity can also contribute to rickets, so advocacy is required to prevent VitDD rickets in Indigenous children.

Full frame machine prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from itClassification
machine, unvalidatedMachine predicted; a candidate call from one source (direct Gemma or distilled Codex), not a consensus.
