Physical Complications in Acute Lung Injury Survivors
Bibliographic record
Abstract
OBJECTIVE: Survivors of severe critical illness frequently develop substantial and persistent physical complications, including muscle weakness, impaired physical function, and decreased health-related quality of life. Our objective was to determine the longitudinal epidemiology of muscle weakness, physical function, and health-related quality of life and their associations with critical illness and ICU exposures. DESIGN: A multisite prospective study with longitudinal follow-up at 3, 6, 12, and 24 months after acute lung injury. SETTING: Thirteen ICUs from four academic teaching hospitals. PATIENTS: Two hundred twenty-two survivors of acute lung injury. INTERVENTIONS: None. MEASUREMENTS AND MAIN RESULTS: At each time point, patients underwent standardized clinical evaluations of extremity, hand grip, and respiratory muscle strength; anthropometrics (height, weight, mid-arm circumference, and triceps skin fold thickness); 6-minute walk distance, and the Medical Outcomes Short-Form 36 health-related quality of life survey. During their hospitalization, survivors also had detailed daily evaluation of critical illness and related treatment variables. Over one third of survivors had objective evidence of muscle weakness at hospital discharge, with most improving within 12 months. This weakness was associated with substantial impairments in physical function and health-related quality of life that persisted at 24 months. The duration of bed rest during critical illness was consistently associated with weakness throughout 24-month follow-up. The cumulative dose of systematic corticosteroids and use of neuromuscular blockers in the ICU were not associated with weakness. CONCLUSIONS: Muscle weakness is common after acute lung injury, usually recovering within 12 months. This weakness is associated with substantial impairments in physical function and health-related quality of life that continue beyond 24 months. These results provide valuable prognostic information regarding physical recovery after acute lung injury. Evidence-based methods to reduce the duration of bed rest during critical illness may be important for improving these long-term impairments.

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.
