Beta-sarcoglycan-deficient muscular dystrophy presenting as chronic bronchopneumonia in a young cat
Bibliographic record
Abstract
CASE SUMMARY: A 5-month-old cat was evaluated for a 3 week history of cough, nasal discharge, decreased appetite and weight loss. Musculoskeletal examination was normal and serum creatine kinase (CK) activity was within the reference interval. The cat was treated during the next 10 months for chronic, persistent pneumonia. Weakness then became apparent, the cat developed dysphagia and was euthanized. Post-mortem evaluation revealed chronic aspiration pneumonia and muscular dystrophy associated with beta (β)-sarcoglycan deficiency. RELEVANCE AND NOVEL INFORMATION: This is the first report of a cat with muscular dystrophy presenting for chronic pneumonia without obvious megaesophagus, dysphagia or prominent neuromuscular signs until late in the course of the disease. The absence of gait abnormalities, marked muscle atrophy or hypertrophy and normal serum CK activity delayed the diagnosis in this cat with β-sarcoglycan deficiency.

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.
