Survival of both twins in a pregnancy complicated by pre-viable cord prolapse at 21 weeks of gestation
Bibliographic record
Abstract
Abstract Background Umbilical cord prolapse is rare but a very serious obstetric emergency. Its incidence has declined over time and significant advances in its management have improved perinatal outcome. Case presentation A 38-year-old woman (gravida 3, para 0) conceived a dichorionic twin pregnancy through in vitro fertilization presented at 21 weeks of gestation with premature rupture of membrane of the presenting twin. At 21+4 weeks’ gestation, cord prolapse of the presenting twin into the vagina was identified by ultrasound. Parents chose conservative management, and planned cesarean section was done at 27+4 weeks. Conclusion Our case demonstrates that conservative management with measures to reduce the risks of infection and a planned delivery can result in positive outcomes even in cases where the cord prolapse occurs prior to viability.

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.
