Incongruent Cerebral Growth in Sudden Infant Death Syndrome
Bibliographic record
Abstract
Sudden infant death syndrome remains a leading cause of post-neonatal mortality in developed countries. Its etiopathogenic mechanisms are unknown. In this neuropathologic study, we noticed that the weights of the brains of infants who died from sudden infant death syndrome (n = 97) were invariably heavier in comparison with those of a group of age-matched controls (n = 23) issuing from the same local population. Brain edema was not a major element, and there were no significant microscopic or macroscopic cerebral anomalies in the brains from either of the study groups. Head circumference did not show a parallel increase in infants with sudden infant death syndrome. The excessive brain weight might reflect abnormal cerebral development and could be detrimental to vital neural control. In a previous study, we disclosed cytokine overexpression in the brains of these victims. Whether increased brain weight is linked to cytokine up-regulation remains, however, a moot case and merits further exploration.

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.
