Preterm premature rupture of membranes Nutritional and socioeconomic factors
Bibliographic record
Abstract
OBJECTIVE: To estimate if there were dietary or socioeconomic factors associated with preterm premature rupture of membranes (PROM). METHODS: In this case-control study, women with preterm PROM (n = 46) were compared with healthy pregnant women matched for gestational age and vitamin supplementation. Measurements included fasting homocysteine, red blood cell folate, albumin, creatinine, and complete blood count. Dietary intake was determined by a food frequency questionnaire. Socioeconomic and demographic factors were recorded. RESULTS: There were no differences between fasting homocysteine, red blood cell folate, and vitamin B(12) levels and dietary intake between patients and controls. There was lower hemoglobin in women with preterm PROM compared with the controls (P <.001). There was a three-fold increased odds of having a total family income of less than $25,000 (Canadian) (odds ratio 3.1, 95% confidence interval 1.6, 6) in women with preterm PROM. CONCLUSION: Preterm PROM is associated with low maternal hemoglobin and low socioeconomic status. There was no association with nutritional intake. The lower hemoglobin level may be a marker for subclinical infection.

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.
