Frailty and Loss of Rectus Femoris Muscle Thickness in Hospitalized Elderly Patients with Community-Acquired Pneumonia – A Case-Control Study
Bibliographic record
Abstract
Frailty is at the core of geriatric syndromes that are characterized by multiple morbidities and mobility limitations. The purpose of this case-control study was to assess the frailty scale and muscle mass on the acute phase in hospitalized elderly patients with community-acquired pneumonia (CAP). Thirty-two elderly patients, aged 75 years or older, who were hospitalized with CAP, and 32 control patients hospitalized without CAP were recruited. Frailty scale and muscle mass were assessed using the Reported Edmonton Frail Scale (REFS) and rectus femoris (RF) thickness by ultrasound, respectively. There was a significant increase in the frequency of frailty among CAP patients (50%), compared with control patients (22%). Frailty scale correlated inversely with RF thickness and activity status. Based upon the piece-wise linear regression analysis between REFS and RF thickness decreased rapidly with the pre-frailty status among CAP patients. Elderly patients with CAP exhibit a significant impairment of activity status with frailty due to decreased thickness of RF prior to admission.

Full frame machine prediction
Teacher imitationNot 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.
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 source (direct Gemma or distilled Codex), not a consensus.
