背景:
本研究探讨了肌肉减少症是否独立预测老年胆结石患者急性胆囊炎(AC)的发生。
方法:
这项回顾性队列研究纳入了1,177名年龄≥65岁、偶然发现胆结石且既往无胆道疾病病史的患者。采用2019年亚洲肌少症工作组(Asian Working Group for Sarcopenia 2019)标准诊断肌少症。主要结局为随访期间急性胆囊炎(AC)的发生,依据2018年东京指南(Tokyo Guidelines 2018)进行判定。采用多变量逻辑回归和Cox回归模型,对年龄、BMI、性别、酗酒史和查尔森合并症指数(Charlson Comorbidity Index)进行校正。
结果:
随访期间,336例患者(28.5%)发生了AC。AC组的肌少症患病率显著更高(38.10% vs. 14.03%;p< 0.001)和较低的平均握力(22.92 ± 12.51 对比 25.50 ± 12.44 kg;p< 0.001)和四肢骨骼肌质量(6.82 ± 2.74 对比 7.67 ± 2.93 kg/m2;p< 0.001),与对照组相比。肌少症使动脉钙化风险独立增加3.56倍(或= 3.564,95%CI:2.619-4.860;p< 0.001)以及使交流电危害增加2.42倍(HR= 2.419,95%CI:1.912-3.060;p< 0.001)。Kaplan-Meier 分析显示,肌肉减少症患者的无房颤生存期显著缩短(log-rankp< 0.001)。严重的肌肉减少症并未在标准肌肉减少症诊断标准基础上带来额外风险。
结论:
肌肉减少症是老年胆结石患者发生急性胆囊炎的一个强有力且独立的预测因子,相较于基于体脂的指标,其风险分层能力更优。常规进行肌肉减少症评估可能有助于识别高风险个体,从而实施针对性的预防干预措施。

Acute Pancreatitis I: Introduction
Acute pancreatitis is characterized by rapid inflammation of the pancreas, often caused by factors like gallstone blockage or excessive alcohol consumption. Chronic pancreatitis, on the other hand, is a slow, progressive inflammation that may result from long-term alcohol abuse, obstructions in the pancreatic duct, or genetic factors.
The causes of acute pancreatitis include:
