Fatal hemorrhagic pneumonia caused by human metapneumovirus in an immunocompetent child
Bibliographic record
Abstract
Human metapneumovirus (hMPV) was recently discovered in 2001 in Holland.This agent causes acute respiratory tract infections in children and adults. 1 The range of clinical manifestations varies from asymptomatic infection to severe pneumonia and acute respiratory failure. 1 -3 When this agent coexists with the respiratory syncytial virus (RSV) in bronchiolitis, symptoms are more severe.4 Williams et al. found, in more than 25 years of investigation, that 12% of lower respiratory tract infections in children was caused by hMPV. 2 Fatal cases of hMPV in both healthy and immunocompromised children have been rarely described in the literature so far.5,6 The aim of the present study was to report the case of a pediatric, immunocompetent patient who presented with severe acute respiratory distress syndrome (ARDS), for whom there was a fatal outcome, and in whom hMPV was the only etiologic agent found even on post-mortem necropsy.

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.
