A25 HOME EXERCISE THERAPY IS WELL TOLERATED AND IMPROVES EXERCISE CAPACITY IN PATIENTS WITH CHILD PUGH A AND B CIRRHOSIS
Bibliographic record
Abstract
Cirrhosis patients have reduced peak aerobic power (peak VO2) that is associated with reduced survival. Supervised endurance training is an effective therapy to increase exercise tolerance in cirrhosis. Many patients have challenges coming in regularly for supervised training. The effect of home-based endurance exercise training (HET) on improving peak VO2 in cirrhosis patients has not been studied. The aim of this pilot study was to evaluate the safety and efficacy of 8 weeks of HET on peak VO2, aerobic endurance (6-minute walk distance), thigh muscle thickness (2D ultrasound) and circumference, and quality of life. Clinically stable patients with cirrhosis were randomly assigned to 8 weeks of HET (n=20) or usual care (controls, n=20). The HET group performed moderate to high intensity (heart rate equal to 60–80% peak VO2) cycle exercise for 3 days per week. An exercise specialist supervised an HET session once every two weeks and had regular telephone contact between these sessions. Paired t-test was used for within group comparisons and analysis of covariance was used to perform between group comparisons. The cohort (n=40) was 58% male, had a mean age of 57 ± 8 years, and 70% had Child Pugh class A cirrhosis. The between group VO2 difference trended to significance (1.7 (-0.33 to 3.7), p=0.09) and the between group 6-minute walk test increased (33.7 (5.1 to 62.4), p=0.02). When within group differences were considered, the HET group had a significant increase in peak VO2 from baseline (17.3 ± 4.5 to 19.0 ± 6.4 mL/kg/min, p=0.03). There was also a significant increase in the thigh circumference (50.6 ± 5.8 to 52.4 ± 6.6 cm, p=0.02) and thigh muscle thickness (1.25 ± 0.40 to 1.31 ± 0.38 cm/m2, p=0.05). There was no significant difference in quality of life and no adverse events occurred during cardiopulmonary exercise testing or HET. Eight weeks of HET is a safe and effective intervention that results in a clinically meaningful improvement in aerobic endurance distance, and trends to improvement in peak VO2 and thigh muscle mass in clinically stable patients with cirrhosis American College of Gastroenterology

Full frame machine prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human 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 source (direct Gemma or distilled Codex), not a consensus.
