概括
低肌肉质量的衡量标准 - - 马塞特肉类遗传症 (Masseter sarcopenia) - - 在患有II型牙骨折的老年患者中显著预测1年死亡率. 早期识别有助于预测和管理.
科学领域:
- 老年创伤的治疗方法
- 整形外科手术 整形外科手术
- 放射学 放射学是一门学科.
背景情况:
- 标志着肌肉质量和功能低下的萨尔科佩尼亚与创伤患者的不良结果有关.
- 老年创伤患者的头部CT扫描使得可以评估大脑肌肉.
- 在II型牙骨折中masseter肉症的预后价值仍未得到研究.
研究的目的:
- 调查II型牙骨折的老年患者中马塞特肉类和死亡率之间的关联.
- 要确定masseter横截面积 (MCSA) 是否可以预测该患者群体的死亡率.
主要方法:
- 50岁以上II型牙骨折和头部CT扫描患者的回顾性队列研究.
- 定义为MCSA 1 SD低于性别特异性平均值.
- 用多变量考克斯回归和卡普兰-梅尔生存分析来评估死亡风险.
主要成果:
- 在72名患者中,有19.4%的患者患有马塞特氏.
- 马塞特的肉症显著预测了一年死亡率 (aHR:5.31,P = .01).
- 整体死亡率在1年内为22.2%,在2年内为30.6%,在5年内为52.8%.
结论:
- 马塞特肉类是患有II型牙骨折的老年患者1年死亡率的重要预测因素.

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...

The upper and lower limb initially develops as a small bulge called a limb bud, which appears on the lateral side of the early embryo. The upper limb bud appears near the end of the fourth week of development, with the lower limb bud appearing shortly after.
Initially, the limb buds consist of a core of mesenchyme covered by a layer of ectoderm. The ectoderm at the end of the limb bud thickens to form a narrow crest called the apical ectodermal ridge. This ridge stimulates the underlying...
