Time Courses of Intrapartum Asphyxia: Neonatal Characteristics and Outcomes
Bibliographic record
Abstract
We compared neonatal characteristics and adverse outcome rates of neonates with hypoxic-ischemic encephalopathy following (1) prolonged partial asphyxia, (2) acute near-total intrapartum asphyxia, and (3) the two combined. The time course of the insult was determined individually by two authors from obstetric data and neonatal charts. "Severe adverse outcome" was defined as death or severe disability detectable by age 2 years. The asphyxial time course was prolonged partial asphyxia in 167 (45%), acute near-total asphyxia in 96 (26%), combined in 78 (21%), and indeterminate in 34 (8%) patients. Among patients with known time course and outcomes, 212 (67%) had severe adverse outcome and 103 (33%) were free of severe adverse outcome. Severe adverse outcome rates were 61% for prolonged partial asphyxia, 67% for acute near-total asphyxia, and 79% for combined time course asphyxia ( P = 0.025). Long-term outcomes differ according to the time course of the insult; infants with combined time course had the worst outcome.

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.
