概括

脊髓损伤 (SCI) 后较高的体重指数 (BMI) 与较低的死亡率有关,而体重不足增加了死亡风险. 这一发现表明潜在的神经代谢途径影响SCI后的生存.

科学领域:

神经科学是一个神经科学.
临床医学临床医学
公共卫生公共卫生

背景情况:

脊髓损伤 (SCI) 后死亡率的增加需要了解生存因素.
体重指数 (BMI) 是影响创伤性SCI后长期结果的潜在因素.

研究的目的:

研究创伤性SCI患者入院时测量的BMI与长期死亡率之间的关联.
在SCI之后确定不同的BMI相关死亡风险组.

主要方法:

这是一项前性纵向队列研究,涉及2004年至2016年期间入院的643名创伤性SCI患者.
用分类和回归树 (CART) 和通用添加模型来分析SCI后7.7年BMI和死亡率.
多变量模型根据人口统计学和伤害特定因素进行调整.

主要成果:

确定了三个死亡风险组:体重不足 (BMI < 17.5 kg/m2),正常体重 (17.5-30.5 kg/m2) 和超重/肥胖 (BMI > 30.5 kg/m2). 这三种死亡风险组分为:体重不足 (BMI < 17.5 kg/m2),正常体重 (17.5-30.5 kg/m2) 和超重/肥胖 (BMI > 30.5 kg/m2).
体重不足的人死亡风险最高 (HR 5.5,P < 0.001).
较高的BMI (>30.5 kg/m2) 显示出对死亡率的保护作用 (HR 0.28,P = 0.029),与肥胖悖论一致.

结论:

住院时的BMI与SCI患者的死亡风险显著相关.
体重不足状态是SCI后长期死亡的一个关键风险因素.
对BMI影响的神经代谢途径的进一步研究是有必要的,以改善SCI患者的生存率.

Spinal Cord Injury ll: Pathophysiology

Spinal Cord Injury ll: Pathophysiology

Spinal cord injury progresses through two interconnected phases: primary injury and secondary injury.Primary InjuryPrimary injury happens at the moment of trauma and involves immediate mechanical damage to the spinal cord.Compression happens when broken vertebrae, herniated discs, or accumulating blood (such as a hematoma) press directly against the spinal cord, distorting its normal shape and function. In cases of contusion, the cord is bruised by a blunt force (like penetrating injuries or...

Secondary Spinal Cord Injury llI: Pathophysiology

Secondary Spinal Cord Injury llI: Pathophysiology

Early Ischemia and Ionic ImbalanceWithin minutes of spinal cord injury, a secondary cascade begins, progressing over hours to weeks. Vascular damage reduces blood flow, causing ischemia and mitochondrial dysfunction. ATP depletion leads to ion pump failure, membrane depolarization, sodium influx, potassium efflux, and water accumulation, resulting in cellular swelling. Increased intracellular calcium further disrupts mitochondria and accelerates cellular injury.Excitotoxicity and Neuronal...
