Intrauterine Growth Patterns in Fetal Gastroschisis
Bibliographic record
Abstract
The objective of this study was to evaluate patterns of intrauterine growth in fetal gastroschisis. This was a retrospective review of prenatally diagnosed cases of fetal gastroschisis delivered at the University of North Carolina Hospital from January 2000 to January 2007. Fetal growth (biparietal diameter, head circumference, abdominal circumference, femur length, and estimated fetal weight) and amniotic fluid volume were evaluated by gestational age. Gastroschisis was diagnosed in 83 pregnancies; outcomes were available in 71 fetuses. The mean gestational age at diagnosis was 17 weeks and 1 day. The mean gestational age at delivery was 35 weeks and 4 days. Mean birth weight was 2306 g. As early as the second trimester, all morphometric measures demonstrated impaired in utero growth, with growth curves shifted to the right of the 50th percentile when compared with a standard population. Estimated fetal weight below the 10th percentile was suspected in 23% of pregnancies, and birth weight at less than the 10th percentile occurred in 47% of neonates. Amniotic fluid volumes remained stable throughout gestation. Fetuses with gastroschisis display impaired intrauterine growth, which is noted in the midsecond trimester of pregnancy and does not appear to progress throughout gestation.

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.
