Abstract

fetched live from OpenAlex

13 patients with chronic obstructive lung disease – 6 with emphysema (E) or emphysema + chronic bronchitis (EB), 7 with pure chronic bronchitis (B) – undertook during 1 year a progressive endurance training, 6 of the subjects continuing for a second year. The E patients were generally more disabled than the B patients, with less lean tissue, poorer muscular endurance, and CO<sub>2</sub> retention during exercise. However, initial tolerance of submaximal aerobic work (65% of age-related normal) was comparable in E and B patients. Eight of the 13 patients noted symptomatic improvements over the first year of conditioning, with reductions of heart rate at a standard submaximal work load and gains of predicted aerobic power (8% in E, 15% in B). Larger improvements were usual in those who exercised faithfully. Gains over the year included increases of muscular endurance (B > E), a small reduction of oxygen debt, a diminution of air trapping and CO<sub>2</sub> retention (E group), and a cessation of deterioration in lung volumes (B group). Symptomatic improvements reflect the support of an interested medical team, increases of muscle strength and gains of cardio-respiratory condition. Training breaks the vicious circle of dyspnoea, inactivity and worsening dyspnoea. The apparent arrest of declining lung volumes in B patients merits confirmation on a larger sample observed for a longer period

Full frame distilled prediction

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.
