Abstract

fetched live from OpenAlex

Background: Wild-type transthyretin amyloidosis (wtATTR) is an important cause of infiltrative cardiomyopathy in older adults. Carpal tunnel syndrome (CTS) is one of the most common extra-cardiac manifestations of wtATTR; however, the prevalence, severity, and risk of recurrence following carpal tunnel release (CTR) remain poorly understood. Methods: This retrospective cohort study reports findings from a single-centre experience of routine neurological screening of newly diagnosed wtATTR patients including nerve conduction studies. Consecutive wtATTR patients between 2014 and 2021 were included. Results: Seventy-nine wtATTR patients were included, 73 (92%) males, mean age of 79 years. Seventy-four (94%) had median neuropathy at the wrist (MNW), 50% having a prior diagnosis with the remaining 50% being diagnosed at screening. The majority with MNW were symptomatic (53, 67%) with moderate or severe disease (66, 84%) bilaterally (42, 53%) on electrophysiologic testing. Nineteen (24%) had recurrent CTS despite previous CTR. At the time of screening, 19 (24%) were prescribed wrist splinting and 36 (46%) were referred for CTR. Conclusions: Carpal tunnel syndrome is common in wtATTR. Most have bilateral disease with moderate to severe MNW at the time of wtATTR diagnosis. Recurrence of CTS after CTR is more common in wtATTR patients than in the general population.

Not 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.
