What is the study measuring?

Primary Outcome Measures

Outcome Measure
Measure Description
Time Frame
Appendicular Skeletal Muscle Index
Time Frame: Day 180 ± 10 days
Appendicular Skeletal Muscle Index (ASMI) = appendicular lean mass (kg) / height² (m²). It reflects muscle mass, used for sarcopenia diagnosis. Lower values indicate muscle loss, linked to aging, malnutrition, or disease.
Day 180 ± 10 days

Secondary Outcome Measures

Outcome Measure
Measure Description
Time Frame
Handgrip strength
Time Frame: Day 180 ± 10 days
Handgrip strength (HGS) = maximum force (kg) measured by a dynamometer. It reflects overall muscle function, predicts disability, morbidity, and mortality. Low HGS indicates sarcopenia, frailty, or poor nutritional status.
Day 180 ± 10 days
Nutrition intake form（MNA）
Time Frame: Day 180 ± 10 days

Mini Nutritional Assessment - Short Form (MNA-SF) consists of 6 items:

  • Appetite and food intake - assesses whether food intake has decreased over the past 3 months.
  • Weight loss - records recent unintentional weight loss.
  • Mobility - determines whether the person can walk independently or is bedridden.
  • Acute disease or psychological stress - checks for stressful events in the past 3 months.
  • Neuropsychological problems - identifies dementia, depression, or other mental disorders that affect eating.
  • Body mass index (BMI) or calf circumference - reflects body fat reserves and muscle mass.

Each item scores 0-3 points. A total score ≤11 indicates a risk of malnutrition. It is commonly used for nutritional screening in elderly populations.
Day 180 ± 10 days
Fried
Time Frame: Day 180 ± 10 days
Fried Frailty Phenotype = a 5-item scale assessing unintentional weight loss, exhaustion, low grip strength, slow walking speed, and low physical activity. item ≥3 = frail; 1-2 = prefrail; 0 = robust. Predicts falls, disability, and mortality.
Day 180 ± 10 days
FRAIL
Time Frame: Day 180 ± 10 days
FRAIL Scale = a 5-item questionnaire: Fatigue, Resistance (climb stairs), Ambulation (walk), Illness (≥5 chronic conditions), and Loss of weight (≥5%). Score 0 = robust, 1-2 = prefrail, 3-5 = frail. Quick screening for frailty in community settings.
Day 180 ± 10 days
SPPB
Time Frame: Day 180 ± 10 days
Short Physical Performance Battery (SPPB) = a 3-component test: standing balance (0-4), 4-meter gait speed (0-4), and 5-repetition chair stand (0-4). Total score 0-12; ≤8 indicates poor physical function, predicts disability, falls, and mortality in older adults.
Day 180 ± 10 days
Muscle mass measured by ultrasound
Time Frame: Day 180 ± 10 days

Ultrasound-based measurements of peripheral skeletal muscles offer a practical, non-invasive, and radiation-free approach for assessing muscle mass in clinical and research settings. In accordance with previously established cut-off values, the following parameters are employed to identify a tendency toward reduced muscle mass:

  1. Biceps brachii cross-sectional area (CSA) - a male-specific indicator, with a value < 7.1 cm² suggesting reduced muscle mass;
  2. Tibialis anterior muscle thickness (MT) - a female-specific indicator, with a value < 2.3 cm suggesting reduced muscle mass;
  3. Rectus femoris muscle thickness (MT) - a gender-neutral rapid screening index, with a value < 1.3 cm serving as a universal cut-off for both men and women, indicating a tendency toward low muscle mass.

These ultrasonographic parameters are intended for initial screening and may assist in the early identification of individuals at risk for sarcopenia, particularly when access to dual-energy X-ray abs
