Abstract

fetched live from OpenAlex

This study examines diagnostic and management practices for preterm premature rupture of membranes before 34 weeks in Canada. Between August and November 2023, obstetricians from the Canadian Preterm Birth Network (28 sites) completed an online survey. The response rate was 79% (n = 22). Preferred diagnostic tests include the fern test (91%) and nitrazine paper test (77%). Home management is offered in 64% of sites. The most used antibiotherapy (55%) combines macrolide and ampicillin followed by amoxicillin. Group B Streptococcus status rarely influences delivery timing (86%). Four sites have no management protocol. Preterm premature rupture of membranes management varies across Canada, highlighting the need for standardization.

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.
