概括

常规大脑脊髓液 (CSF) 测试在肌缩侧面硬化症 (ALS) 中显示出有限的临床实用性. 然而,像Aβ42这样的神经退行标志物可以预测ALS的生存率和进展.

科学领域:

神经学神经学
生物化学生物化学
神经科学是一个神经科学.

背景情况:

在肌缩侧面硬化症 (ALS) 中常规脑脊液 (CSF) 测试的临床实用性尚未得到充分证实.
生物化学CSF数据与ALS中神经退行症标志物没有相关性.

研究的目的:

为了研究腰部穿刺在ALS患者的临床效用.
为了将CSF的生物化学概况与ALS的临床和预后数据相关联.

主要方法:

收集和分析了140名ALS患者的CSF概况.
评估的CSF蛋白质,白蛋白,IgG,IgG指数,白蛋白系数 (QAlb),t-tau,p-tau,以及Aβ42.
与临床和生存数据相关联的CSF标志物.

主要成果:

在约25%的ALS患者中发现了CSF蛋白,白蛋白和QAlb的升高,但缺乏临床或生存关联.
异常的神经退行症标志物值在26.3%至35.4%之间.
p-tau/t-tau比率和Aβ42与ALS进展率和生存时间相关;Aβ42是最强的预后标志物.

结论:

标准的CSF生物化学标记在ALS中没有明显的临床或预后价值.
易于测量的神经退行标志物,特别是Aβ42,可以帮助预测ALS生存率和诊断时的进展.

Local Anesthetics: Clinical Application as Spinal Anesthesia

Local Anesthetics: Clinical Application as Spinal Anesthesia

Spinal anesthetics are given during lower abdomen and limb surgeries to block sensory and motor neurons. They are administered in the mid to low lumbar regions, primarily acting on the cauda equina's nerve roots. The blockade level depends on the local anesthetic (LA) concentration. Usually, low LA concentrations are sufficient to block sensory fibers, while only high LA concentrations block motor fibers. Other factors like injection volume and speed, the patient's posture, and the drug...
