- 肝病学 肝病学是一种肝病学.
- 病毒学 病毒学
- 移植医学 移植医学 移植医学
背景情况:
- 肝炎E病毒 (HEV) 是肝炎的常见原因,经常被诊断不足,特别是在移植接受者中.
- 免疫抑制的个体面临更高的慢性HEV感染的风险.
- 标准诊断依赖于IgM抗HEV抗体,但这在某些人群中可能不可靠.
研究的目的:
- 在移植接受者中报告肝炎E病例.
- 为了突出HEV在免疫受损患者的诊断挑战.
- 在免疫抑制患者中证明自发病毒清除.

Kidney Transplant I: Introduction
514
A kidney transplant is a surgical approach that involves replacing a non-functioning kidney with a healthy one from a donor. This procedure is often a treatment option for end-stage renal disease (ESRD) patients. The method requires careful recipient selection, including evaluating various medical and psychosocial factors. These criteria vary between transplant centers but generally include assessments of the patient's overall health, adherence to medical recommendations, and lifestyle...

Effect of Hepatic Disease on Pharmacokinetics: Pathophysiologic Assessment and Liver Function Test
212
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...

Esophageal Varices-II: Clinical Features and Management
619
Esophageal varices often manifest as gastrointestinal bleeding episodes, presenting symptoms like hematemesis (vomiting of blood), hematochezia (passing fresh blood via the rectum), and melena (black, tarry stools). Other signs can include weight loss, anorexia, abdominal discomfort, jaundice, pruritus, altered mental status, and muscle cramps.
In the initial assessment, a thorough review of the patient's medical history is vital to identify risk factors such as liver disease, alcohol...

Kidney Transplant III: Nursing Management
417
Postoperative Nursing Management for Kidney Transplant PatientsPostoperative nursing management care includes monitoring the surgical site, encouraging early movement, and promoting lung health through breathing exercises. Nurses also administer prescribed medications like H2-blockers, such as famotidine, or proton pump inhibitors, like omeprazole, to help prevent gastrointestinal ulcers and bleeding. Fungal infections in the mouth and bladder can result from immunosuppressive and antibiotic...

Diseases of the Liver and Gallbladder
2.1K
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...
