Abstract
The collection of exhaled breath condensates (EBC) is a noninvasive method for obtaining samples from the lungs. Eicosanoids are lipid mediators implicated in the asthmatic inflammatory response. The objective of our study was to investigate whether the profile of eicosanoid lipid mediators in EBC can characterize the inflammation in asthma and chronic obstructive pulmonary disease (COPD). EBC samples were collected from 22 healthy controls (C), 25 mild intermittent asthmatics (MIA), 20 with moderate to severe asthma (MSA) and 20 with moderate to severe COPD. EBC samples were analyzed by unique tandem mass spectrometry that allows the quantification of up to 25 eicosanoid mediators simultaneously. No differences were found between MIA and C. Subjects with MSA and COPD had higher levels of 6-keto, PGE2, LTB4, 11-12 EET and AA, while lower levels of LXA4, 11DHyTxB2, 11HETE and 8,9EET, when compared to MSA and C (p < 0.05). Our study shows that the analysis of EBC through mass spectrometry is mixed and has a similar response in MSA and COPD when compared to MIA and controls.

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 it
