Abstract

fetched live from OpenAlex

Maternal antibody transfer in pregnancy and breastmilk is implicated in the development of allergen-specific responses in children. Human studies investigating the effect of maternal allergen-specific IgG (sIgG) on allergic diseases in offspring are limited. Maternal sIgG in breastmilk and serum was measured in a subset of the CHILD birth cohort using an allergen macroarray and compared against sIgE of the child at 12-months (n=266). Hierarchical clustering of breastmilk sIgG was used to analyze the impact on atopic outcomes via multivariable logistic regression models. Breastmilk sIgG did not directly correlate with 12-month outcomes regardless of maternal atopic status. Higher breastmilk sIgG was a significant risk factor for skin prick test positivity at 12-months to food (OR 1.90 [1.07-3.41], p=0.030). Mean breastmilk/serum sIgG were significantly lower among IgE-sensitized children for cashew and Ara h 2, and higher for almond and ovalbumin. Relative abundance of breastmilk/serum sIgG may affect IgE-sensitization in offspring.

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.
