Epidemiology of Acute Viral Gastroenteritis in Children Hospitalized in Rouen, France
Bibliographic record
Abstract
This study assessed the epidemiologic characteristics of acute viral gastroenteritis in hospitalized children. A stool sample obtained from each child was analyzed for the presence of astrovirus, calicivirus, rotavirus, adenovirus, enterovirus, and digestive bacteria. Of the 438 stool samples obtained, 138 tested positive for > or =1 pathogen during the winters of 1997-1998 and 1998-1999 (P<.001). Virologic tests revealed rotavirus in 17.3% of samples, calicivirus in 7.3%, astrovirus in 6.8%, adenovirus in 0.7%, and > or =1 virus in 5.4%. Median age was higher for patients with rotavirus gastroenteritis than it was for those with astrovirus or calicivirus gastroenteritis (P=.014). Mean duration of hospitalization was statistically significantly lower for children with rotavirus gastroenteritis (P=.022), despite the more-frequent dehydration observed among children with rotavirus versus those with astrovirus or calicivirus gastroenteritis (P=.007). In contrast, enteral rehydration was more rapidly achieved in patients with gastroenteritis due to rotavirus.

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.
