利皮多米克 (Lipidomics) 是一种消化剂.

背景情况:

与代谢功能障碍相关的脂肪性肝病 (MASLD) 需要可访问的诊断方法.
目前对MASLD的诊断方法可能是侵入性的或复杂的.
临床上有必要进行临床检查,以确定MASLD.

研究的目的:

为了识别用于检测MASLD的最小脂质生物标志物面板.
使用脂质组分析开发MASLD的预测模型.
建立一个非侵入性,点的护理MASLD诊断测试的基础.

主要方法:

来自MASLD患者和对照者的血样本使用超高性能液态染色体质谱学 (UPLC-MS) 脂管学进行了分析.
进行了循环eicosanoids,相关的生物活性代谢物和自由脂肪酸的有针对性的定量.
生物信息学方法和多变量分析 (AUROC) 用于识别预测性脂质生物标志物.

主要成果:

一组由15种脂质代谢物 (12种eicosanoids,3种自由脂肪酸) 组成的小组被确定为MASLD的预测.
脂质组小组实现了高度准确的MASLD预测,AUROC为0.999.
一项验证研究证实了 MASLD LIPIDOMICS SCORE,证明了它的预测能力.

结论:

一个新的脂质代谢物的小组可以准确地识别患有MASLD的个体.
开发的MASLD LIPIDOMICS SCORE显示出对非侵入性护理点诊断测试的承诺.
需要进一步的大规模研究来优化和验证该预测模型的临床用途.

Effect of Hepatic Disease on Pharmacokinetics: Pathophysiologic Assessment and Liver Function Test

In clinical practice, the direct measurement of hepatic blood flow to evaluate liver function presents significant challenges due to the intricate and specialized nature of the necessary techniques. Consequently, healthcare professionals often rely on empirical estimates derived from thorough patient examinations and liver function tests to gauge liver health. Among the tools at their disposal, the Child–Pugh and MELD scoring systems stand out for their ability to categorize and assess...
