Significance of Phototherapy-Induced Riboflavin Deficiency in the Full-Term Neonate
Bibliographic record
Abstract
As a result of impaired fatty acid oxidation, a characteristic urinary dicarboxylic aciduria occurs in the riboflavin deficient animal. We compared the occurrence of riboflavin deficiency induced by phototherapy with changes in urinary organic acid profiles in 8 full-term, breast-fed neonates who received phototherapy for hyperbilirubinemia, and in 10 full-term, breastfed controls. Riboflavin status was assessed by measuring flavin adenine dinucleotide saturation of erythrocyte glutathione reductase. All 8 neonates exposed to phototherapy developed riboflavin deficiency (p less than 0.001). Riboflavin deficiency was progressive with the duration of phototherapy. None of the controls was riboflavin deficient. Urine organic acid profiles indicative of mitochondrial acyl-CoA dehydrogenase activity (fatty acid beta-oxidation, quantitated by gas chromatography mass spectrometry) showed no changes between the study and control groups in mono-, di-, or tricarboxylic acids or other organic acids. The riboflavin deficiency induced by phototherapy in full-term neonates was not of sufficient severity to limit riboflavin-dependent fatty acid oxidation.

How this classification was reachedexpand
Full frame distilled prediction
Teacher imitationNot 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.
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 teacher head, not a consensus.
