New Insights in Occult Psoriatic Arthritis
Bibliographic record
Abstract
Since the 1970s, asymptomatic involvement of several musculoskeletal structures was described in patients with psoriatic arthritis (PsA). We recently designated this clinical condition as occult PsA. This concept addresses an "underground" inflammatory process that can eventually cause structural damage. The percentage of PsA cases occurring in an occult manner remains to be determined but it does not seem small. From a teaching perspective, we suggest differentiating occult PsA into 3 subsets: real occult PsA, characterized by a continuous asymptomatic course; temporary occult PsA, in which the clinical course remains asymptomatic for a period; and limited occult PsA, which occurs asymptomatically in some areas of the body but is clinically evident in others. Some serum biomarkers could identify patients to be studied with imaging techniques to discover real occult PsA. Since an asymptomatic course was also reported for other spondyloarthropathies, the concept of occult arthritis could be expanded to the whole field of such conditions.

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.
