Ultrasound findings on patients with juvenile idiopathic arthritis in clinical remission
Bibliographic record
Abstract
OBJECTIVE: To assess whether children with juvenile idiopathic arthritis (JIA) in clinical remission show pathologic findings on either gray-scale or power Doppler ultrasound of their joints. METHODS: Children with JIA were eligible if they were in clinical remission for at least 3 months, as defined by the absence of clinically active joints and serologic markers of inflammation. Gray-scale as well as power Doppler ultrasonography of the wrist, knee, and ankle were carried out on previously affected joints and unaffected contralateral joints. Images were read by 2 independent readers. Findings were categorized as 1) structural abnormalities in the case of synovial thickening or increased joint fluid on gray-scale ultrasound or 2) power Doppler positive in the case of an abnormal power Doppler signal. RESULTS: The study cohort consisted of 28 patients. Eight of 14 patients with previous wrist involvement had pathologic gray-scale findings, and 3 of these 14 patients also had pathologic Doppler findings in the wrist. None of the 20 patients with past knee involvement had pathologic gray-scale or Doppler findings in the knee. Six of 15 patients with previous ankle involvement had pathologic gray-scale findings and 1 of the 15 patients had pathologic Doppler findings in the tibiotalar joint. CONCLUSION: This study demonstrates that some patients who meet clinical criteria for remission continue to show ongoing pathology on joint ultrasound, which may be suggestive of persistent inflammation.

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.
