Abstract
I would like to thank the authors of Physician and parent barriers to the use of oral corticosteroids for the prevention of paediatric URTI-induced acute asthma exacerbations at home, published in the July 2017 issue for their contribution in our efforts to understand and improve translational medicine; their opinions are valuable and welcome. Unfortunately, they have directed their talents to study barriers preventing physicians and parents from adopting a treatment strategy that is controversial at best and widely rejected at worst. The authors studied 27 children (52% of which were preschoolers) and report on barriers to the use of parent-initiated oral corticosteroids (OCS) at the onset of a upper respiratory tract infection (URTI) to prevent acute asthma exacerbations—a strategy which they describe as ‘effective in the management of acute asthma’ and its use as a ‘key message to paediatricians’ (1). To support this contention, they cite a 10-year-old American Guideline (2) from the National Heart Lung and Blood Institute; a recommendation that has remained unchanged from an even earlier 1997 version of this Guidleine (3)—despite 20 years of published research to inform a more contemporary view. In addition, the authors further cite two Cochrane reviews (4,5) as evidence that administering oral steroids at the onset of URTI symptoms can improve asthma-related outcomes. These Cochrane Reports, however, examined the rapid benefits of the addition of OCS to reduce asthma-related symptoms in patients receiving standard asthma therapy in an Emergency Department (ED). Although it may be tempting to extrapolate these findings to support the strategy of parent-initiated OCS at the onset of all URTIs at home, that was not the objective of those reviews and should not be generalized to support that approach when other, more direct evidence is available.

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.
