A unique retinal epitheliopathy is associated with amyotrophic lateral sclerosis/Parkinsonism‐Dementia complex of Guam
Bibliographic record
Abstract
BACKGROUND: The aim of this work was to examine whether a linear retinal pigment epitheliopathy is associated with the amyotrophic lateral sclerosis/parkinsonism-dementia complex of Guam. METHODS: A total of 918 Guamanian Chamorros, with and without amyotrophic lateral sclerosis/parkinsonism-dementia complex, were examined cross-sectionally for linear retinal pigment epitheliopathy (LRPE). Overall, 239 Guamanians, who were neurologically asymptomatic, were followed for up to 20 years to determine the risk of developing amyotrophic lateral sclerosis/parkinsonism-dementia complex. RESULTS: The epitheliopathy was present in 59.7% (117 of 196) patients with amyotrophic lateral sclerosis/parkinsonism-dementia complex, but in only 24.7% (178 of 722) of subjects who were neurologically asymptomatic (age- and sex-adjusted risk difference: 35.0%; 95% confidence interval [CI]: 27.5-42.6; p < 0.0001). Prospectively, 15 of 50 cases with epitheliopathy developed amyotrophic lateral sclerosis/parkinsonism-dementia complex, compared to 4 of 189 cases without epitheliopathy (age- and sex-adjusted hazard ratio: 13.1; 95% CI: 4.0-43.1; P < 0.0001). CONCLUSION: Amyotrophic lateral sclerosis/parkinsonism-dementia complex is associated with an LRPE and predicts future neurological disease. Identifying the cause of this retinopathy could provide an understanding about the pathogenesis of amyotrophic lateral sclerosis/parkinsonism-dementia complex and related diseases.

How this classification was reachedexpand
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 itClassification
machine, unvalidatedMachine predicted; a candidate call from one teacher head, not a consensus.
