The clinical research of perioperative neurocognitive dysfunction in brain tumor patients
Bibliographic record
Abstract
Objective To study the clinical characteristics of the perioperative cognitive dysfunction in brain tumor patients. Methods One hundred and forty cases of brain tumor patients were evaluated by using the Chinese vesion of Montreal Cognitive Assessment Questionnaire before and after surgery. The distribution and clinical features of cognitive dysfunction in different located lesions and pathological types were analyzed and compared. Results Among the 140 brain tumor patients, the preoperative cognitive impairment and prevalence rate were 59.2%, the score was 24.2±2.4.The postoperative cognitive impairment and prevalence rate were 80.7%, the score was 20.5±4.1.The postoperative cognitive dysfunction prevalence was significantly higher than the preoperative in benign and malignant with infra or supratentorial brain tumor patients(80.0% vs 98.3%, 71.8% vs 92.2%, all P<0.05). Conclusions Vary different extent cognitive impairment was found in brain tumor patients in preoperative period. The postoperative cognitive dysfunction was seriously worse than that in the preoperative period in malignant and supratentorial brain tumors in earlier recovery period.

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.
