Abstract

fetched live from OpenAlex

Eosinophilic/T-cell chorionic vasculitis (ETCV) is characterized by mixed T-cell, eosinophilic, and histiocytic infiltrates within the chorionic vessel wall. We sought to better characterize this lesion with respect to other pathologic correlates and the T-cell populations involved. Epidemiologic data and other pathologic diagnoses, including concurrent chronic villitis (CV), were tabulated for each case of ETCV diagnosed at our institution over a 6-year period. CD3, CD25, FOXP3, and dual FOXP3-CD3 immunostains were used to identify regulatory T-cell populations in ETCV and CV. Cells positive for CD3, FOXP3, and CD25 were quantitated by manual counts of ×40 fields at the sites of ETCV and CV, and FOXP3∶CD3 and CD25∶CD3 ratios were calculated. Digital analysis of ETCV and CV using the dual FOXP3-CD3 immunostain was also performed on select cases. Of 31 ETCV cases, 10 (32%) were accompanied by CV and 13 (42%) by a thrombus in the vessel affected by ETCV. The mean Treg cell marker∶CD3 ratios in ETCV ranged from 0.18 to 0.26 by manual count and digital analysis, but the counts did not statistically differ by method. The mean Treg cell marker∶CD3 ratios in CV ranged from 0.37 to 0.39 by manual count and 0.19 by digital analysis, but these counts also did not statistically differ by method. Chronic villitis was seen in one-third of ETCV cases. FOXP3+ and CD25+ regulatory T cells represent a significant subpopulation of T cells in ETCV and CV, suggesting that they may play a role in these entities.

Teacher imitation

Not 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.
