Estimation of Red Blood Cell Volume in Premature Infants With and Without Respiratory Distress Syndrome
Bibliographic record
Abstract
Red blood cell volume was estimated indirectly from plasma volume and venous hematocrit measurements in 262 consecutively delivered premature infants of less than 37 weeks' gestation. Infants with respiratory distress syndrome averaged lower red cell volumes (P0.02) than those without. Fatal cases had the lowest volumes. There was a 10.3% mortality from RDS (respiratory distress syndrome) among the one third of infants with the smallest red cell volumes, and only a 2.3% mortality among the one third with the largest volumes. Red cell volume was shown to be a direct correlate of time of cord clamping and thereby of the amount of placental transfusion, both in infants with and without RDS. From this study it is probable that delayed cord clamping, by allowing placental transfusion, decreases the risk of death from RDS in premature infants. Delay in clamping the umbilical cord for 1-1.5 min is advised in premature births.

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.
