Abstract
Necrotizing enterocolitis (NEC) is the most common gastrointestinal emergency in preterm neonates, with a mortality rate of 30-50% in advanced cases. Despite decades of research, its multifactorial pathophysiology remains incompletely understood. This review summarizes recent advances in NEC research and proposes an integrative theoretical framework for its pathogenesis. We examine key contributing factors, including intestinal vascular development, mucosal immunity, intestinal regeneration, the enteric nervous system, and the gut microbiome, highlighting how prematurity disrupts these processes and predisposes neonates to NEC. Furthermore, we propose a sequential model of NEC pathogenesis, hypothesizing that impaired intestinal microcirculation in preterm neonates compromises blood flow in response to enteral feeding, leading to localized ischemia. This initiates epithelial barrier dysfunction, exacerbates inflammatory responses, impairs intestinal regeneration, and disrupts enteric nervous system function, collectively driving NEC progression. By integrating experimental and clinical findings, we provide a comprehensive perspective on NEC initiation in preterm neonates and identify potential avenues for future research and therapeutic interventions.

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
