Abstract

fetched live from OpenAlex

Inflammatory cell infiltration and afferent neuropathy have been shown in the upper airway (UA) mucosa of subjects with obstructive sleep apnea (OSA). We hypothesized that inflammatory and denervation changes also involve the muscular layer of the pharynx in OSA. Morphometric analysis was performed on UA tissue from nonsnoring control subjects (n = 7) and patients with OSA (n = 11) following palatal surgery. As compared with control subjects, inflammatory cells were increased in the muscular layer of patients with OSA, with CD4+ and activated CD25+ T cells (both increased approximately threefold) predominating. Inflammation was also present in UA mucosa, but with a different pattern consisting of CD8+ (2.8-fold increase) and activated CD25+ (3.2-fold increase) T cell predominance. As ascertained by immunoreactivity for the panneuronal marker PGP9.5, there was a dramatic (5.7-fold) increase in intramuscular nerve fibers in OSA patients compared with control subjects, as well as direct evidence of denervation based on positive immunostaining of the muscle fiber sarcolemmal membrane for the neural cell adhesion molecule in patients with OSA. These data suggest that inflammatory cell infiltration and denervation changes affect not only the mucosa, but also the UA muscle of patients with OSA. This may have important implications for the ability to generate adequate muscular dilating forces during sleep.

Teacher imitation

Not 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.
