Clinical Features and Outcomes of Takayasu Arteritis with Neurological Symptoms in China: A Retrospective Study
Bibliographic record
Abstract
OBJECTIVE: To describe the clinical features and longterm outcomes of patients with Takayasu arteritis (TA) in China who experienced neurological symptoms. METHODS: A retrospective study was undertaken of patients with TA who attended a single study center from 2002 to 2013, who also exhibited neurological symptoms (n = 274). Clinical and imaging features were analyzed, as well as longterm outcomes. RESULTS: The mean age at disease onset was 28.2 ± 11.2 years, with a female-to-male ratio of 4.3:1. The most common neurological manifestation was dizziness (214, 78.1%), the most frequent type of TA was type III (112, 40.9%), and the most common affected artery was the left subclavian (147, 53.6%). Involvement of 3 or 4 branches of the aortic arch was observed in 28% of patients. Among 30 patients experiencing a stroke (10.9%), steno-occlusive lesions of the subclavian artery and common carotid artery were frequently observed in patients with ischemic stroke, while steno-occlusive lesions of the descending aorta, abdominal aorta, and/or renal arteries were more frequently observed with hemorrhagic stroke. Heart failure was the most common cardiovascular event in those who died (n = 6) and in surviving cohorts. CONCLUSION: Neurological features in patients with TA were variable, and correlated with the number of arteries and the site of artery involvement. Resistant hypertension was one of the most important risk factors for hemorrhagic stroke in patients with TA.

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.
