Abstract
OBJECTIVES: To describe the interference of herpes zoster (HZ) pain and discomfort with activities of daily living (ADLs) and health-related quality of life (HRQL) during the acute rash phase, and to quantify the relationship between acute HZ pain and discomfort and impaired ADLs and HRQL in older persons. METHODS: Prospective, observational study of 160 HZ outpatients age > or =60 at 4 US study sites who completed the Zoster Brief Pain Inventory (ZBPI), Zoster Impact Questionnaire (ZIQ), McGill Pain Questionnaire, EuroQol, and SF-12 questionnaires on a predetermined schedule. Patients rated interference on a 0 to 10 scale for ADL items in the ZBPI and the ZIQ. Interference scores were averaged to create summary measures for the ZBPI items (ZBPI ADLI) and ZIQ items (ZIQ ADLI). A composite pain score was used in mixed-effects models analyses of the association between pain and discomfort and ADLI and HRQL measures during the first 35 days after HZ rash onset. RESULTS: HZ pain interfered with all ADLs but interference was greatest for enjoyment of life, sleep, general activity, leisure activities, getting out of the house, and shopping. For every 1.0 point increase in pain and discomfort intensity, there was a 0.69 and 0.53 point increase in ZBPI and ZIQ interference, respectively, and a 2.81 point, 1.57 point, and 1.95 point decrease in EuroQol, SF-12 physical, and SF-12 mental scales, respectively. DISCUSSION: Acute zoster pain and discomfort has a significant negative impact on functional status and HRQL in older adults. The magnitude of interference increases with increasing pain and discomfort intensity.

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
