概括
这项研究确定了老年刚果成年人中阿尔茨海默病 (AD) 的认知和血生物标志物概况. 研究结果显示,阿尔茨海默氏症的认知和生物标志物模式与西方人群中观察到的类似.
科学领域:
- 神经学 神经学
- 老年学是一门学科.
- 生物标志物 生物标志物
背景情况:
- 西方研究确定了阿尔茨海默病 (AD) 的认知和血生物标志物概况.
- 低收入和中等收入国家缺乏这样的个人资料.
- 这项研究通过检查老年刚果成年人的个人资料来解决这个差距.
研究的目的:
- 确定老年刚果成年人可能患有阿尔茨海默病 (pAD) 的认知和血生物标志物概况.
- 将这些资料与健康对照 (HC) 的资料进行比较.
- 评估刚果人口中已确定的生物标志物的诊断准确性.
主要方法:
- 这是一项对114名50岁以上参与者 (56名pAD,58名HC) 的横截面研究.
- 使用DSM-5-TR,CSID,AQ和非洲神经心理学电池 (ANB) 进行诊断和认知评估.
- 使用的变异分析 (ANOVA) 用于具有p < 0.05显著性的统计分析.
主要成果:
- 在pAD患者中,认知缺陷显著更高,特别是在口头记忆,视觉空间记忆,语言,面部感知和执行功能方面.
- 降低的阿贝塔42/40比率,增加的粉样蛋白概率评分 (APS) 和Apoe4在pAD患者中占主导地位.
- 阿贝塔40,阿贝塔42和ptau181水平在各组之间没有显著差异.
结论:
- 刚果老年人可能患有阿尔茨海默病的认知和生物标志物概况与西方研究的发现一致.
- 这表明某些AD诊断标志物的潜在普遍性.
- 强调需要文化适应的诊断工具和在不同人群中进行进一步研究.

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...
