Role of Proton Pump Inhibitors on Rapid Urease Test (PYLO DRY) and Histopathological Examination
Bibliographic record
Abstract
According to previous studies, if there was a low density of Helicobacter pylori in the stomach, then rapid urease test requires longer time to become positive. Density of Helicobacter pylori could be reduced by recent use of PPIs, hence rapid urease test may require longer reading time as well. The main objective was to determine the effect of PPI on the results of rapid urease test (PYLO DRY) and histopathology. Two antral biopsies were obtained from 35 dyspeptic patients, who underwent gastro intestinal endoscopy from March 2015 to July 2015. An informed consent from all patients and approval from the institutional ethical committee were obtained before proceeding. Antral biopsies were subjected for rapid urease test (PYLO DRY from HALIFAX RESEARCH LABORATORY KOLKATA, INDIA) and histopathologic examinations. The results of Rapid urease test were observed after 1 hour and 24 hours. The histopathologic examinations were used as the gold standard. PYLO DRY was positive in 17.6% ( Eight were positive during histopathological examination. In our study, 24 hours Rapid urease test yeilded higher sensitivity but lower specificity compared to RUT at 1 hour for diagnosis of H.pylori infection in patients who were on PPI.

How this classification was reachedexpand
Full frame distilled prediction
Teacher imitationNot 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.
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 teacher head, not a consensus.
