Human Metapneumovirus (hMPV) Infection in Children With Cancer
Bibliographic record
Abstract
Human metapneumovirus (hMPV) has recently emerged as an important cause of lower respiratory tract infections in hospitalized children, causing severe pneumonia and respiratory failure among immunocompromised patients. We retrospectively examined 30 children diagnosed with cancer whose nasopharyngeal swabs were positive for hMPV by direct fluorescent testing over a 5-year period. In 16/30 (53.3%) children, infection was confined to the upper respiratory tract, whereas lower respiratory tract infection occurred in 46.7%. The median duration of respiratory illness was 6.5 days with a hospital admission rate of 66.6%. No mechanical ventilation was required because of hMPV infection. Bronchoalveolar lavage tested positive for hMPV in 1 patient requiring prolonged inhaled steroid and bronchodilator therapy. All children recovered completely from hMPV infection. hMPV causes upper and lower respiratory tract infections in immunocompromised children. Infections may result in significant disease but is usually not fatal. In the absence of specific anti-viral drug, good symptomatic therapy appears to be the optimal therapy.

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.
