Intraabdominal Vancomycin-resistant Enterococcus Infections
Bibliographic record
Abstract
GOALS: To determine the clinical course and outcome in patients with intraabdominal vancomycin-resistant enterococcus infections (VRE-A) and to identify probable risk factors for VRE-A. BACKGROUND: Vancomycin-resistant enterococcus is one of the most notable nosocomial emerging pathogens. The incidence is increasing, especially in the abdominal surgery setting. STUDY: A comparative study of patients with VRE-A and VRE infection in other sites (VRE-O) who were hospitalized for over 1 year. Fisher exact test and Student t test were used; a two-tailed p value of less than 0.05 was considered to be significant. RESULTS: Of 89 nine patients with VRE, six had VRE-A, 24 had VRE-O, and 59 had VRE colonization. The VRE-A group was comprised of one patient with an inoperable Klatskin tumor and biliary sepsis, one with acquired immune deficiency syndrome and an infected pancreatic pseudocyst, two with fecal peritonitis, and two with biliary sepsis after surgery for common bile duct stones. All six patients with VRE-A had recent surgery before VRE isolation, as compared with three in the VRE-O group (p = 0.0001). Despite adequate treatment with intravenous chloramphenicol, resulting in eradication of VRE in all six VRE-A cases, the mortality rate remained high at 50%. CONCLUSIONS: Vancomycin-resistant enterococcus should be recognized as an emerging nosocomial pathogen that causes potentially fatal intraabdominal infections in the postsurgical setting. However, the impact of treatment on ultimate outcome needs further evaluation.

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.
