概括

低体重指数 (BMI) 的老年患者在关节骨折手术后面临更高的并发症和死亡风险. 这突出了BMI.

科学领域:

老年医学老年医学
整形外科手术整形外科手术
公共卫生公共卫生

背景情况:

关节骨折是老年人发病和死亡的主要原因.
低体重指数 (BMI) 与骨质疏松症和虚弱有关,但其对部骨折手术结果的影响尚不清楚.

研究的目的:

为了研究低BMI与经过关节骨折手术的老年患者的术后结果之间的关联.
为了评估BMI的预后价值在关骨折患者的外科手术风险分层.

主要方法:

使用日本诊断程序组合 (DPC) 数据库进行的回顾性队列研究 (2016年4月 - 2022年3月).
包括65岁以上接受关节骨折手术的患者.
定义的低BMI为<17.0公斤/平方米 (敏感性分析<18.5公斤/平方米).
使用倾向得分匹配 (1:1) 和后勤回归来分析结果.

主要成果:

低BMI (<17.0 kg/m2) 与明显更高的尿路感染,肺炎和住院死亡率有关.
低BMI组需要更高的外科手术期间输血量.
静脉血栓栓塞 (VTE) 发生率在低BMI组较低.
敏感性分析证实了这些发现.

结论:

低体重指数是老年人骨骨折手术后并发症和死亡率增加的独立风险因素.
在这个患者群体中,BMI是术后风险评估和管理的关键因素.

Bone Disorders

Bone Disorders

Aging and its effect on bone remodeling is the most common cause of bone disorders. In young and healthy people, bone deposition and resorption happen at an equal rate to maintain optimal bone health.
Bone deposition is also affected by the levels of sex hormones like estrogen and testosterone that promote osteoblast activity and bone matrix synthesis. When the level of these hormones decreases due to aging, it causes a reduction in bone deposition. As a result, bone resorption by osteoclasts...
