Does primary surgical closure of the patent ductus arteriosus in infants <1500 g or ≤32 weeks’ gestation reduce the incidence of necrotizing enterocolitis?
Bibliographic record
Abstract
BACKGROUND: The hemodynamic perturbation related to patent ductus arteriosus (PDA) is associated with a higher risk of necrotizing enterocolitis (NEC). OBJECTIVE: To determine whether primary surgical closure, as compared with treatment with indomethacin or exposure to prophylactic indomethacin, reduces the incidence of NEC in preterm infants <1500 g and/or ≤32 weeks' gestation with clinically and echocardiogram-identified PDA. METHODS: The literature was reviewed using the methodology for systematic reviews for the Consensus of Science adapted from the American Heart Association's International Liaison Committee on Resuscitation. RESULTS: Ten studies were reviewed. The incidence of NEC was not lower in infants who underwent primary surgery for closure of the PDA compared with infants treated with indomethacin or infants exposed to prophylactic indomethacin (level of evidence 2). CONCLUSION: Primary surgical closure of the PDA cannot be recommended as an intervention to decrease the incidence of NEC in infants <1500 g and/or ≤32 weeks' gestation.

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.
