概括
一些与粉样蛋白相关的成像异常-H微出血可能会消失,这挑战了人们认为它们是永久性的信念. 这一发现通过展示ARIA-H的动态性质,影响了管理阿尔茨海默病免疫疗法.
科学领域:
- 神经学 神经学
- 放射学 放射学是一门学科.
- 免疫治疗是一种免疫疗法.
背景情况:
- 与粉样蛋白相关的成像异常 (ARIA) 是阿尔茨海默病抗粉样蛋白免疫疗法的不良事件.
- ARIA呈现为水/溢出 (ARIA-E) 或微出血/病 (ARIA-H).
- 传统上,ARIA-H被认为是永久性血红蛋白染色.
研究的目的:
- 为了调查ARIA-H微出血的潜在解决方案.
- 挑战对ARIA-H永久性的既定理解.
主要方法:
- 来自Gantenerumab阿尔茨海默氏病试验的MRI扫描的回顾性分析.
- 同时注册和神经放射学家对串行T2*GREMRI序列的审查.

01:20Blood Studies for Cardiovascular System I: Cardiac Biomarkers
749
Cardiac biomarkers are enzymes, proteins, and hormones released into the blood when cardiac cells are injured. They are powerful tools for triaging.
The essential diagnostic tools for detecting myocardial necrosis and monitoring individuals suspected of having acute coronary syndrome (ACS) include:
Troponins
Troponins, particularly cardiac troponins I and T, are the most precise and sensitive markers of myocardial injury. They are detectable within 4-6 hours of myocardial injury and remain...

01:19Blood Studies for Cardiovascular System II: CRP, Hcy, and Cardiac Natriuretic Peptide Markers
516
Cardiac biomarkers are critical in diagnosing, prognosing, and managing cardiovascular diseases. Routine measurement of specific biomarkers such as B-type natriuretic peptide (BNP), C-reactive protein (CRP), and homocysteine (Hcy) is common practice in clinical settings to evaluate heart function and predict cardiovascular events.
These markers indicate stress or strain on the heart muscle:
Natriuretic Peptides (BNP)
Cardiac myocytes produce these hormones in response to ventricular stretching...
