Management of the patent ductus arteriosus in preterm infants
Bibliographic record
Abstract
Management of the patent ductus arteriosus (PDA) is one of the most contentious topics in the care of preterm infants. PDA management can be broadly divided into prophylactic and symptomatic therapy. Prophylaxis with intravenous indomethacin in extremely low birth weight infants may reduce severe intraventricular hemorrhage. Echocardiography should be routinely used to confirm the presence of a PDA before considering symptomatic therapy. A symptomatic PDA can be managed conservatively, using pharmacotherapy or with procedural closure. Ibuprofen should be considered as the pharmacotherapy of choice for a symptomatic PDA. High-dose ibuprofen may be preferable, especially for preterm infants beyond the first 3 to 5 days of age. If pharmacotherapy fails (after two courses) or is contraindicated, procedural closure may be considered for infants with a persistent PDA with significant clinical symptoms in addition to echocardiographic signs of a large PDA shunt volume and pulmonary over-circulation.

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.
