Cerebrovascular disease and pneumonia in the elderly
Bibliographic record
Abstract
Pneumonia is a common cause of death in elderly people. A series of our studies have demonstrated that pneumonia in the elderly is characterized by silent aspiration, impaired swallowing and cough reflex, partly due to cerebral infarctions at basal ganglia. These infarctions probably induce the disruption of the specific central neurotransmitter system including dopamine and substance P, which plays an important role for swallowing and cough reflex. Use of ACE inhibitor and stimulation of the oral cavity by simple oral care, which are effective in increasing substance P. reduced the incidence of aspiration pneumonia. Moreover, use of a dopamine agonist such as amantadine hydrochloride and a folic acid supplement that are known to potentiate dopaminergic neurons also prevented aspiration pneumonia. For patients bedridden due to lowered ADL, it is essential for them to keep an upright position a few hours after meals to prevent aspiration pneumonia caused by the reflux of ingested foods. Also, administration of neuroleptics may cause aspiration pneumonia by suppression of dopaminergic neurons.

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.
