Bacterial Endotoxins in Umbilical Cord Blood of Neonates
Bibliographic record
Abstract
We tested umbilical cord blood from 255 infants for evidence of bacterial endotoxins. Using a Limulus lysate gelation technique, endotoxin-like activity (ELA) was detected in 13 (9.1%) of 142 term infants and in 23 (20.3%) of 113 preterm infants (p less than 0.05), in concentrations ranging from 30 to 3,000 pg Escherichia coli equivalent activity per milliliter of plasma. No factors predisposing to endotoxemia could be detected in term pregnancies but among ELA+ premature infants, placental cultures more frequently revealed gram-negative species (p less than 0.05). Cord blood endotoxemia in the concentrations observed was without obvious consequence in mothers and term infants. Our data confirm the existence of natal endotoxemia, a potential mechanism of perinatal injury.

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.
