Abstract

fetched live from OpenAlex

‘Gastritis’ is the microscopic evidence of inflammation of the gastric mucosa, indicating histologic evaluation of biopsy samples. The overall incidence of gastritis is not well known. Incidence of Helicobacter pylori is low in western Europe, the United States, and Canada. Hemorrhagic gastritis may be associated with hematemesis, anemia, melena, and occult blood in stool. H. pylori is a gram-negative bacterium responsible for nodular gastritis in humans and is the most common cause of gastritis worldwide. Viral infections related to gastritis include cytomegalovirus, Epstein–Barr Virus, human herpes virus-7, influenza, and herpes simplex virus. Giardia is a rare cause of gastritis and seems to affect those with abnormal gastric acid secretion. Nonsteroidal anti-inflammatory drug -related gastritis is secondary to topical irritation and inhibition of cyclo-oxygenase, and can occur after the first dose. Gastritis in patients with ulcerative colitis is not uncommon, but is usually mild and not granulomatous.

Fetched live from OpenAlex and de-inverted. Abstracts are not stored in this database: the inverted indexes are 8.6 GB of the frame’s 9.3 GB of text, and the host has 13 GB free.

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.
