Characteristics of nontyphoidal Salmonella gastroenteritis in Taiwanese children: A 9-year period retrospective medical record review
Bibliographic record
Abstract
Nontyphoidal Salmonella is among the most common causes of acute pediatric gastroenteritis in Taiwan. It is important to study antibiotic resistance patterns in nontyphoidal Salmonella isolated from children. Therefore, the objective of this study was to investigate the prevalence of serogroups and susceptibility to antimicrobial nontyphoidal Salmonella isolated from Taiwanese children with gastroenteritis. A retrospective review of the medical records of patients aged under 18 years with a diagnosis of acute gastroenteritis at a regional hospital located in southern Taiwan from August 2000 to August 2009 was conducted. Patients whose records documented stool cultures positive for nontyphoidal Salmonella underwent serogrouping and antimicrobial susceptibility testing. Of the 1938 patients diagnosed with acute gastroenteritis, 100 (5.2%) had nontyphoidal Salmonella infections. Most of the cases of nontyphoidal Salmonella gastroenteritis occurred during the summer months of July and August. The most common Salmonella strains isolated were classified as belonging to serogroup B (51%). Three cases had blood cultures that tested positive for nontyphoidal Salmonella , all of which were classified as belonging to serogroup C 2 . Isolates from the stool cultures of 23 cases that occurred between 2007 and 2009 were further tested to determine their antimicrobial susceptibility profiles, and 87% of these isolates were sensitive to two common third-generation cephalosporins (cefotaxime and ceftriaxone). In conclusion, the results of this nine-year period medical record review study suggested that although extended-spectrum cephalosporins were more effective than ampicillin and ciprofloxacin in treating childhood nontyphoidal Salmonella gastroenteritis, only 87% of isolates were susceptible to these agents. Prevention through proper hygienic practices to minimize potential exposure to nontyphoidal Salmonella is clearly a better strategy than treating patients with antibiotics following the incidence of infection.

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.
