概括
内皮功能障碍生物标志物与老年人的认知表现较差有关. 然而,这项研究没有发现随着时间的推移与认知能力下降的相关性,这表明与当前认知有通用联系.
科学领域:
- 神经科学是一个神经科学.
- 心血管科学 心血管科学
- 老年学是一门学科.
背景情况:
- 内皮功能障碍 (ED) 越来越被认为是影响大脑健康的因素.
- 关于ED生物标志物与认知功能之间的关联的先前研究产生了相互矛盾的结果.
- 了解这种关系对于确定认知健康干预的潜在目标至关重要.
研究的目的:
- 评估内皮功能障碍的血生物标志物与认知表现之间的关联.
- 为了研究内皮功能障碍和随着时间的推移认知能力下降之间的关系.
- 为了澄清内皮功能障碍在认知衰老中的作用.
主要方法:
- 利用了来自荷兰八个群体 (年龄为57-93岁) 的9414名个体的数据.
- 将血生物标志物 (sICAM-1,sVCAM-1,E-selectin) 组合成一个复合ED得分.
- 使用线性回归和元分析来检查与认知领域的横截面和纵向关联.
主要成果:
- 更高的ED综合分数与更差的执行功能,处理速度,延迟的记忆和注意力有交叉相关性.
- 在ED和即时记忆或语言表现之间没有发现显著的关联.
- 在内皮功能障碍和随着时间的推移而发生的认知变化之间没有观察到任何关联.
结论:
- 这项大规模的元分析表明,内皮功能障碍与认知表现差异之间存在着一致的,尽管很小的,截面关联.
- 这些发现不支持内皮功能障碍和认知衰退之间的纵向联系.
- 观察到的ED与当前认知的关联可能是一个一般的效应,而不是特定于某些认知领域.

61
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...

2
Clinical manifestationsPeripheral Arterial Disease (PAD) manifests through a range of symptoms, from the characteristic intermittent claudication to atypical presentations and severe complications in advanced stages. Intermittent claudication, a hallmark symptom of PAD, presents as exercise-induced muscle pain that typically resolves within minutes of rest. This pain is reproducible and stems from inadequate blood flow, leading to the accumulation of lactic acid produced during anaerobic...
