概括
酒精泡退化症 (AFD) 是一种被诊断不足的疾病,模仿酒精相关性肝炎 (AH). 高水平的甘油三可以帮助区分AFD,它有更好的预后和独特的遗传特征.
科学领域:
- 肝病学 肝病学是一种肝病学.
- 胃肠病学 胃肠病学
- 内部医学 内部医学
背景情况:
- 酒精泡退化症 (AFD) 与酒精相关性肝炎 (AH) 相似,但具有独特的组织学.
- 关于AFD流行,预后和非侵入性诊断工具的数据有限.
研究的目的:
- 为了确定AFD的患病率和预后.
- 调查用于区分AFD和AH的诊断工具.
- 分析AFD和AH之间的遗传表达差异.
主要方法:
- 疑似AH的患者肝脏活检分析.
- 将其分为AFD,AH或基于组织学的其他发现.
- 临床特征,组织学和基因表达的分析.
- 国家酒精滥用和酒研究所 (NIAAA) 标准和诊断的实验室参数的评估.
主要成果:
- 在8%的患者中诊断出AFD (18/230).
- AFD 病例显示更多的肥胖症,较少的纤维化,和不同的基因表达模式 (低调的纤维化/炎症,高调的脂质代谢/线粒体功能).
- AFD患者的长期存活率显著改善 (100%对AH的57%;P=.002).
- 血清甘油三水平 (≥225 mg/dL) 显示出AFD诊断的高精度 (AUC 0.886),超过了NIAAA标准.
结论:
- 在疑似与酒精有关的肝炎患者中,酒精泡退化并不罕见.

Alzheimer's Disease: Overview
492
Alzheimer's Disease (AD) is a continually advancing neurodegenerative disorder, distinguished by escalating memory loss, cognitive dysfunction, and dementia. The disease unfolds in three stages: preclinical, mild cognitive impairment (MCI), and dementia. Its onset is insidious, and the progression gradual, with the cause not well explained by other disorders.
The clinical diagnosis of AD hinges on the presence of memory and other cognitive impairments. Biomarkers, such as changes in Aβ...

Mass Spectrometry: Alcohol Fragmentation
3.5K
Alcohols (R-OH) ionize to lose one non-bonded electron from the oxygen atom, forming molecular ions. Due to their tendency to fragment rapidly, the intensity of the molecular ion peak in the mass spectrum is weak or sometimes absent. The fragmentation patterns for alcohols occur in two ways, i.e. ⍺-cleavage and dehydration. During ⍺-cleavage, the bond at the ⍺-position adjacent to the hydroxyl group cleaves to give a resonance-stabilized cation and a radical. However,...
