Trace Elements in Meconium from Preterm and Full-Term Infants
Bibliographic record
Abstract
Meconium samples from 23 preterm infants (birth weight = 1,097 +/- 359 g; gestational age 29 +/- 3 weeks, mean +/- SD) and 27 full-term infants (3,453 +/- 476 g; 39.5 +/- 1 weeks) were analyzed for zinc, copper, manganese, chromium and iron by atomic absorption spectrometry. Compared to meconium from preterm infants, full-term infants had an elevated (p less than 0.05) total excretion (microgram) of zinc (957 +/- 545 vs. 503 +/- 506), copper (245 +/- 256 vs. 128 +/- 94) and manganese (62 +/- 55 vs. 29 +/- 29), but not iron (190 +/- 147 vs. 332 +/- 532) or chromium (0.4 +/- 0.19 vs. 0.75 +/- 1.0). Two preterm infants had high losses (1.5 and 2 mg) of iron in their meconium. Zinc, copper and manganese losses into meconium appear to increase with gestation, whereas iron and chromium losses occur early in gestation and may be reabsorbed by term.

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.
