科学领域:

病毒学病毒学
流行病学流行病学
公共卫生公共卫生

背景情况:

肝炎E病毒 (HEV) 包含八种基因型,具有不同的宿主和传播途径.
HEV-1和HEV-2是人类特异性的,而HEV-3和HEV-4具有来自猪等动物的动物感染潜力.
生态和社会经济因素显著影响HEV的全球分布.

研究的目的:

审查非洲的肝炎E病毒 (HEV) 流行病学.
了解HEV传播动态,包括水borne和zoonotic路线.
为该地区的HEV流行病监测和控制策略提供信息.

主要方法:

关于非洲HEV流行病学研究的文献综述.
对HEV基因型,传播途径和风险因素的分析.
检查用于HEV检测的诊断测试开发和应用.

主要成果:

通过便污染的水传播是非洲发展中国家HEV流行病的主要原因.
越来越多地认识到从猪传播给人类的动物性传染,这对农民和屠夫构成风险.
HEV感染对孕妇构成严重风险,可能导致产妇和胎儿死亡.
HEV与无法解释的症状和错误诊断的病例有关,这强调了需要准确诊断的需要.

结论:

在非洲,HEV是一个重要的公共卫生问题,传播模式多样化.
"一个健康"的方法对于理解和减轻动物传播的HEV传播至关重要.
加强监测和诊断能力对于控制非洲的HEV至关重要.

Diseases of the Liver and Gallbladder

Diseases of the Liver and Gallbladder

Liver and gallbladder diseases are a significant health concern, with prominent conditions including cirrhosis, hepatitis, non-alcoholic fatty liver disease (NAFLD), and gallstones. Jaundice is a common manifestation of liver and biliary disease.
Cirrhosis is characterized by the scarring of hepatic lobules in the liver, which are replaced by fibrous tissue, affecting the liver's normal functioning. NAFLD, on the other hand, is caused by an excessive build-up of fat in the liver, not...

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...
