Abstract

fetched live from OpenAlex

A 20-day-old female infant was transferred from a peripheral hospital with progressive vomiting and weight loss. The infant was born to a 31-year-old primiparous mother at 37 weeks' gestation by spontaneous vaginal delivery. The pregnancy was uncomplicated, apart from a positive screen for group B streptococcus, which was adequately treated during labour. The infant's birth weight was approximately 3 kg. Vomiting began at seven days of age, when nystatin was started for treatment of oral thrush. The vomiting progressively became more frequent and projectile in nature. By the time of admission, at three weeks of age, the infant had projectile nonbilious vomiting that occurred 1 h to 2 h after every attempted feeding. She appeared hungry immediately after vomiting. The infant had been offered two different formulas (Enfamil [Mead Johnson Nutritionals, Ottawa, Ontario] and Goodstart [Nestlé Canada]), and minimal expressed breastmilk by bottle since birth. The formula changes did not result in symptomatic improvement. She was offered approximately 60 mL of feed every 2 h to 3 h. Her bowel movements were normal, apart from a few loose, nonbloody stools on the day of admission. Her parents reported that there had been four to five wet diapers per day before admission. The infant was otherwise healthy, with no fever, rash or systemic symptoms.

Fetched live from OpenAlex and de-inverted. Abstracts are not stored in this database: the inverted indexes are 8.6 GB of the frame’s 9.3 GB of text, and the host has 13 GB free.

Not 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.
