Preterm Premature Rupture of Membranes
Bibliographic record
Abstract
In Brief 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 B12 levels anddietary 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. Preterm premature rupture of membranes is associated with indicators of lower socioeconomic status and low maternal hemoglobin levels and is not associated with dietary intake or serum levels of folate, homocysteine, or vitamin B12.

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.
