Blood Studies for Cardiovascular System I: Cardiac Biomarkers01:20

Blood 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...

Blood 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...

科学领域:

  • 神经科学是一个神经科学.
  • 公共卫生 公共卫生
  • 数据科学数据科学数据科学

背景情况:

  • 国际合作通过数据共享,提高可复制性和知识交流来加强AD/ADRD研究.
  • 了解参与国际合作的AD/ADRD研究人员的特征和数据共享实践对于优化全球研究工作至关重要.
  • 本研究旨在描述AD/ADRD研究人员与或没有国际合作者,重点关注他们的数据共享实践和经验.

研究的目的:

  • 将AD/ADRD研究人员的人口统计,研究经验和数据共享实践与国际合作者或没有国际合作者进行比较.
  • 检查国际合作对AD/ADRD研究界的数据共享经验和成果的影响.

主要方法:

  • 一项跨部门调查 (NIH-1R01AG080093-01) 收集了关于数据共享实践和经验的自我报告数据.
  • 使用本杰明尼-霍赫伯格校正的奇平方测试用于比较人口统计,数据共享实践和研究人员与国际合作者之间的经验 (α < 0.05).

主要成果:

  • 在585名受访者中,193人 (33%) 有国际合作者. 这些研究人员更有可能是男性,白人,有更长的研究经验,是ADRC的研究人员,并且出版率更高.
  • 国际合作者更有可能在美国境外分析/生成数据,并参与正式的数据共享 (提出和接收请求).
  • 尽管数据共享活动增加,但与国际合作的研究人员报告了更多负面的数据共享结果 (43.8%对20.3%).

结论:

  • 国际合作与AD/ADRD研究中的数据共享增加有关,但与人口差异和更高的负面数据共享经验的可能性有关.
  • 需要进一步的研究,以阐明连接国际合作,数据共享实践和AD/ADRD研究公平性的机制.
  • 解决研究人员代表性的差异和数据共享的负面结果对于最大限度地发挥全球研究伙伴关系的好处至关重要.
