Abstract

fetched live from OpenAlex

Extract Bronchiectasis is a chronic pulmonary disorder characterized by irreversible dilatation of the bronchi, leading to chronic cough, sputum production, and recurrent respiratory infections [1]. Among the pathogens colonizing the airways of patients with bronchiectasis, Aspergillus species are notable due to their potential to exacerbate inflammation and contribute to disease progression [2]. While colonization by Aspergillus is recognized in bronchiectasis [3, 4], the differential impact of transient versus persistent colonization on clinical outcomes is not well understood. The presence of Aspergillus in the airways can range from transient colonization, where the fungus is intermittently present, to persistent colonization, characterized by continuous presence over time [3, 4]. Understanding the implications of these colonization patterns is crucial for guiding clinical management and therapeutic interventions. Outside of allergic bronchopulmonary aspergillosis (ABPA) [5], this has not been systemically evaluated in bronchiectasis. We aimed to evaluate the effects of transient and persistent Aspergillus colonization on clinical outcomes in bronchiectasis, hypothesizing that persistent colonization would be associated with worse outcomes.

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.
