- 老年病的医生 老年病的医生
背景情况:
- 轻度认知障碍 (MCI) 和轻度痴呆症的诊断依赖于认知测试和脑MRI.
- 识别用于认知表现的简单MRI标记物有助于对阿尔茨海默氏病嫌疑人的早期干预.
- 本研究检查了基于MRI的脑小血管病变 (CSVL) 和脑缩与认知评分相关的视觉评分尺度.
研究的目的:
- 在MRI和认知测试得分 (TMSE,MoCA-泰国) 上调查CSVL视觉评分尺度和脑缩之间的关联.
- 为了在被诊断为记忆障碍性MCI或轻度痴呆症的患者中探索这些关联.
主要方法:
- 100名患有记忆障碍性MCI或轻度痴呆症的患者的横截面研究.
- 认知测试 (TMSE或MoCA-泰国) 和脑部MRI,用于CSVL (Fazekas,微血,缺口) 和缩 (GCA,MTA) 的视觉评分尺度.
- 使用了斯皮尔曼的相关性和多重回归分析.
主要成果:

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...
