Abstract
The purpose of this study was to determine the short-term outcome of newborns less than 30 weeks gestation when there is definite placental histologic chorioamnionitis. A retrospective analysis was performed of records of all neonates delivered at our institution from January 1989 through January 1999. This information was retrieved from our perinatal database and pathology database. The population was stratified according to the presence or absence of histologic chorioamnionitis. Statistical analysis was performed using student t-test and Mann-Whitney method. Logistic regression was used to control for potential confounding variables. There were 392 neonates less than 30 weeks gestation delivered during this time period. Complete placental histology was available for 342 patients (87.4%). Histologic chorioamnionitis was identified in 140 (40.9%) cases. Those with histologic chorioamnionitis delivered sooner (26.3 versus 27.5 weeks), were of lower birth weight (920.1 versus 1029.8 g), and had lower 5-minute Apgarscores. Neonatal septicaemia and pneumonia were strongly associated with underlying histologic chorioamnionitis. There was a significant reduction in the incidence of respiratory distress syndrome (RDS) when histologic chorioamnionitis was present. Severe histologic chorioamnionitis increases the risk of premature delivery and is strongly associated with neonatal sepsis. There is a significant reduction in the incidence of RDS and neonatal mortality.

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 it
