Abstract

fetched live from OpenAlex

Perinatal metabolism of vitamin D was studied in premature babies with the aim of: (1) reporting the relationship between the pregnant mother and her preterm infant and the metabolism of vitamin D during the first weeks of life, and (2) assessing the effect of vitamin D metabolites on phosphorus calcium and magnesium intestinal absorption. There was only a positive correlation between plasma cord calcium and 25-hydroxyvitamin D levels and the mother's plasma levels at birth. During the hypocalcemic episode observed during the first week of life, vitamin D activation did occur, but later on rickets or osteomalacia cannot be due to the low levels of vitamin D metabolites in the preterm receiving an adequate dose of vitamin D (1,000-1,200 IU of D2). Calcitriol, the major metabolite of vitamin D, is acting on the intestine and promotes calcium absorption even in very tiny prematures. The pathogenesis of hypomineralization in the preterm infant is due to the low intake of calcium or phosphorus and/or poor absorption of calcium in the case of vitamin D deficiency.

Teacher imitation

Not calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model 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.
