Hypersensitivity Pneumonitis in a Hardwood Processing Plant Related to Heavy Mold Exposure
Bibliographic record
Abstract
Two workers employed in a hardwood floor plant presented symptoms suggestive of hypersensitivity pneumonitis (HP). At that plant, kiln-dried wood often shows moldy growth and is subsequently brought inside for processing. This study evaluated the environment in attempt to identify the causative antigen and verify whether other workers of this and similar plants had or were at risk of developing HP. Dust from dust-removing systems and molds on the surface of wood planks were collected and air samples taken from a sister plant. Blood samples, spirometry, and symptoms' questionnaires were obtained from 11 co-workers. Dense Paecilomyces growth was observed on the surface of the dried processed wood in the index plant. This fungal genus was not detected in the sister plant. An additional worker had symptoms suggestive of HP, and his bronchoalveolar lavage revealed a lymphocytic alveolitis. The 3 confirmed cases of HP and the other 10 workers had positive specific IgG antibodies to Paecilomyces. We report 3 cases of HP out of 13 workers and a 100% sensitization to molds in workers of a hardwood processing plant. This rate is much higher than what is commonly seen in other environments associated with HP. The drying process is suspected of being responsible for the massive Paecilomyces contamination likely responsible for the HP.

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.
