Challenge Exposure to Isocyanates Induces Changes in Nasal Patency in Patients Reporting Work-Related Respiratory Symptoms
Bibliographic record
Abstract
OBJECTIVE: To examine the utility of specific inhalation challenge (SIC) in assessing the nasal congestive response to isocyanate exposure. METHODS: Nine patients complaining of work-related respiratory symptoms underwent SIC with exposure to isocyanate for 4 and 120 minutes on different days. Nasal volume was monitored by acoustic rhinometry and nasal congestion by the visual analogue scale (VAS) for up to 6 hours. RESULTS: The 4-minute isocyanate SIC induced a nonsignificant fall in nasal volume and no increase in the VAS score. The 120-minute isocyanate SIC induced a significant fall in nasal volume at 15, 30, and 60 minutes postchallenge that was associated with a significant increase in the VAS score at 15 and 30 minutes postchallenge. CONCLUSIONS: SIC appears useful to assess changes in nasal patency after exposure to isocyanate. Exposure to isocyanates can induce nasal congestion that can be objectively monitored during SIC.

How this classification was reachedexpand
Full frame distilled prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model 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 teacher head, not a consensus.
