背景/目的:我们评估了纤维化-4(FIB-4)是否与中国台湾地区≥65岁成年人的肌肉衰减症及功能状态相关,并探讨其作为老年筛查工具的价值。方法:在这项横断面研究(2023年7月—2025年7月)中,共评估了537名年龄≥65岁的门诊患者。FIB-4通过标准公式计算得出;对于年龄≥65岁者,采用≥2.0作为高风险阈值。将参与者分为低FIB-4组和高FIB-4组进行比较。功能状态通过日常生活基本活动能力(ADLs)、工具性ADLs以及步态与平衡测试进行评估。肌力低下定义为肌肉力量降低。同时记录共病情况、老年综合征及实验室检查结果。结果:高FIB-4组年龄更大(78.6 ± 6.0 岁 vs. 75.6 ± 5.8 岁),女性比例较低,且BMI较低。高FIB-4组的POMA评分和工具性日常生活活动(ADL)评分较低,而基本ADL评分和起立-行走计时测试(TUG)持续时间差异无统计学意义。高FIB-4组低握力的发生频率更高。在按性别分层的分析中,FIB-4在女性中与年龄和天冬氨酸转氨酶(AST)呈正相关,与血小板计数、白细胞计数、握力、POMA评分及工具性ADL评分呈负相关。回归分析显示,低握力与高FIB-4评分相关,但在老年女性中,无论是否考虑混杂因素,该关联均不再显著。在肌少症组中,较低的BMI和较高的白细胞计数是高FIB-4评分的危险因素。结论:FIB-4 不仅反映肝脏纤维化的风险,还与老年人群的虚弱状态相关,尤其是与肌肉力量减退(dynapenia)及功能衰退相关。结合年龄调整的截断值,FIB-4 可作为实用的早期预警筛查工具,与营养评估和身体功能表现评估联合应用。

Pharmacokinetics in Geriatric Patients: Effect of Age on Drug Excretion01:18

Pharmacokinetics in Geriatric Patients: Effect of Age on Drug Excretion

In geriatric patients, renal physiology undergoes significant changes, including diminished renal blood flow and a lower glomerular filtration rate (GFR), leading to alterations in medication clearance. Drugs such as aminoglycoside antibiotics, lithium, and digoxin, which rely on glomerular filtration for removal from the body, particularly impact pharmacokinetics. These drugs tend to have slower clearance rates in older adults, necessitating careful dosage considerations.Evaluation of renal...

Pharmacodynamics in Geriatric Patients: Effects of Age

Age-related pharmacokinetic changes are extensively documented, but understanding age-related pharmacodynamic alterations is relatively limited. This knowledge gap can be partly attributed to the complexity of developing appropriate measures of drug responses compared to bioanalytical methods for determining drug concentrations.Most information regarding age-related differences in human pharmacodynamics originates from cross-sectional studies. However, these studies assume that observed mean...

Drug Dosing in Renal Diseases: Estimation of Glomerular Filtration Rate Based on Serum Creatinine Concentration01:28

Drug Dosing in Renal Diseases: Estimation of Glomerular Filtration Rate Based on Serum Creatinine Concentration

Glomerular filtration rate (GFR) can be estimated from serum creatinine using the modification of diet in renal disease (MDRD) formula or the chronic kidney disease–epidemiology collaboration (CKD–EPI) equation. Both methods are widely used in clinical practice to assess kidney function and guide treatment decisions.The MDRD equation does not require weight or height measurements and is normalized to the body surface area of 1.73 m², considered the average adult surface area.

Pharmacokinetics in Geriatric Patients: Effect of Age on Drug Distribution01:00

Pharmacokinetics in Geriatric Patients: Effect of Age on Drug Distribution

Drug distribution in the human body is influenced by several factors, including plasma protein concentration, body composition, blood flow, tissue-protein concentration, and tissue fluid pH. Among these, changes in plasma protein concentration and body composition due to aging significantly affect how drugs are distributed within the body. Specifically, aging is associated with a decrease in albumin levels by about 10% and an increase in α1-acid glycoprotein levels. These alterations are...
