Consensus document on controversial issues in the diagnosis and treatment of bloodstream infections and endocarditis
Bibliographic record
Abstract
BACKGROUND: The treatment of severe bloodstream infections (sepsis, endocarditis, and infections of vascular prostheses) caused by Gram-positive microorganisms is made even more difficult by the emergence of resistant strains. The introduction of new antibiotics with activity against these strains has created new opportunities, but many controversial issues remain. CONTROVERSIAL ISSUES: The aim of this GISIG (Gruppo Italiano di Studio sulle Infezioni Gravi) working group - a panel of multidisciplinary experts - was to define recommendations for some controversial issues using an evidence-based and analytical approach. The controversial issues concerned the duration of therapy and role of aminoglycosides and teicoplanin in the treatment of Gram-positive bacterial endocarditis, the optimal use of the new antibiotics in the treatment of bloodstream infections caused by resistant Gram-positive strains, and the use of microbiological techniques (i.e., bactericidal serum testing and synergy testing) and of pharmacokinetic data (e.g., monitoring of plasma levels of antibiotics) in the treatment of difficult-to-treat Gram-positive bloodstream infections. METHODS: A systematic literature search of randomized controlled trials and/or non-randomized studies was performed mainly using the MEDLINE database. A matrix was created to extract evidence from original studies using the CONSORT method to evaluate randomized clinical trials and the Newcastle-Ottawa Quality Assessment Scale for non-randomized studies. The GRADE method for grading the quality of evidence and strength of recommendation was applied.

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.
