Pregnant Pause? Not for IBD Care—A Single Tertiary Care Center Prospective Cohort Study Affirming IBD Management in Pregnancy
Bibliographic record
Abstract
Background: This study examined Inflammatory Bowel Disease (IBD) management and outcomes during pregnancy in a tertiary care setting, focusing on disease activity, medication use, and maternal and neonatal outcomes. Methods: A prospective cohort study followed 287 women with IBD through 291 pregnancies from 2017 to 2023 at a single tertiary care center, collecting data preconception, during each trimester, and postpartum. Results: The study observed a 92.7% live birth rate. Seventy-four percent of individuals were in clinical remission preconception, and disease activity increased throughout pregnancy, particularly in ulcerative colitis (UC) patients (peaking at 37% in the second trimester), while remaining stable in CD patients. UC, disease duration <5 years, and preconception activity correlated with higher disease activity during pregnancy. Biologic use remained stable without significant impact on outcomes. Preterm delivery (6.7%) and small for gestational age infants (7%) rates reflected baseline population risk. Steroid use was associated with higher preterm delivery rates. Gestational hypertension (6.9%) and diabetes (9.4%) rates were similar to population norms. Maternal adverse events were higher in women 40 or older (OR 3.893). Conclusions: This study reaffirms the safety of continued medical therapy for IBD throughout pregnancy in a tertiary care, prospective cohort. Increased disease activity throughout pregnancy was evident, particularly in UC. Despite higher rates of disease activity amongst those with UC, outcomes were similar in those with CD vs UC-suggesting that disease activity measures have limitations in CD and pregnancy, or there is some mild inherent risk of CD in pregnancy outcomes irrespective of disease activity.

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.
