Gastric Glassy Cells: A Study of 3202 Gastrectomy Specimens from Dwellers of the Atlantic and Pacific Basins
Bibliographic record
Abstract
Fifteen years ago we detected gastric cells with glassy cytoplasm (GCs) in the human pyloric antrum. The frequency of these cells was subsequently investigated in sections from gastrectomies carried on in populations dwelling on the rim of the Atlantic and Pacific basins. In this work we compared the results obtained in these disparate geographic regions. We reviewed sections from 3203 gastrectomies (1942 in the Atlantic basin and 1261 in the Pacific basin). In the Atlantic basin 12/1942 (0.6%) of the gastrectomies had GCs, whereas in the Pacific basin 26/1261 (2.1%) of the gastrectomies had GCs. The difference was significant (p<0.05). The proportion of gastrectomies with GCs was higher in patients in Vancouver, Canada, than in New York, and higher in Santiago de Chile than in Buenos Aires, despite the fact that these populations reside at approximately the same geographic latitude. Previous studies with the same material indicated that both the extension of intestinal metaplasia and the frequency of ciliated metaplasia were significantly higher in the Pacific than in the Atlantic basin. Hence, the difference in the frequencies of GCs appears to be a new indication that dissimilar environmental exposures in the two basins might have influenced the histological make-up of the gastric mucosa.

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.
