Abstract

fetched live from OpenAlex

Asthma is often not recognised and is frequently not diagnosed and treated in older people. This may reflect the belief that the disease is unlikely to manifest late in this group. We report a patient who presented with a respiratory infection and persistent breathlessness after the age of 80. Asthma was not initially suspected, and other diagnoses were pursued. However, subsequent spirometry suggested late age-onset asthma that responded dramatically to appropriate treatment. This case provides a timely reminder for physicians to consider this diagnosis in older patients.

Fetched live from OpenAlex and de-inverted. Abstracts are not stored in this database: the inverted indexes are 8.6 GB of the frame’s 9.3 GB of text, and the host has 13 GB free.

Not 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.
