<i>Streptococcus pneumoniae</i>infection: a Canadian perspective
Bibliographic record
Abstract
Streptococcus pneumoniae infections have resulted in significant morbidity and mortality worldwide in children and adults. In Canada, Streptococcus pneumoniae remains one of the leading causes of infectious disease including pneumonia, meningitis, bacteremia and otitis media. Although the widespread use of pneumococcal conjugate vaccines (PCVs) in Canadian children has reduced the incidence of pneumococcal diseases associated with vaccine-serotypes, rapid increase of non-vaccine serotypes in carriage and pneumococcal infections is of great concern to clinicians. The main goal of this review is to provide an overall picture of invasive pneumococcal diseases (IPD) in Canada for the past few decades, including serotype changes and shifts in antibiotic resistance patterns. The effects of PCV vaccines on incidence, serotype distribution, antibiotic resistance of pneumococcal infections and nasopharyngeal (NP) carriage are discussed. We also examined historical outbreaks of Streptococcus pneumoniae and their public health impact. Recent developments in universal protein vaccines against pneumococcus show promise.

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.
