概括
深髓静脉 (DMV) 的结构变化通过损害淋巴功能,加剧脑小血管疾病 (CSVD) 的认知衰退. DMV评分可能有助于早期检测.
科学领域:
- 神经学 神经学
- 神经成像是一种神经成像.
- 血管神经学 血管神经学
背景情况:
- 大脑小血管疾病 (CSVD) 与认知能力下降有关.
- 深髓静脉 (DMV) 和淋巴系统功能障碍与CSVD有关.
- 淋巴功能在CSVD相关认知障碍中的调解作用尚不清楚.
研究的目的:
- 在CSVD患者中调查DMV结构变化,淋巴系统功能障碍和认知衰退之间的关系.
- 为了确定受损的淋巴功能是否调解了DMV异常和认知障碍之间的关联.
主要方法:
- 从93名CSVD患者的临床和MRI数据的回顾性分析.
- 评估DMV负担使用半定量得分 (0-18) 在敏感度加权成像.
- 使用蒙特利尔认知评估 (MoCA) 评估淋巴功能通过扩散张力图像分析沿周围血管空间 (DTI-ALPS) 索引和认知功能.
主要成果:
- 较高的DMV分数与MoCA分数 (r = -0.48,p<0.001) 和DTI-ALPS指数 (r = -0.28,p<0.001) 有负相关性.
- DTI-ALPS指数与MoCA分数呈正相关性 (r=0.35,p<0.05).该指数与MoCA分数呈正相关性 (r=0.35,p<0.05).
- 调解分析显示,DTI-ALPS指数部分调解了DMV负担对认知表现的影响 (占总影响的14.08%).
结论:
- 肌肉神经动脉结构异常可能会通过干扰淋巴功能来导致CSVD相关的认知障碍.
- DMV评分显示,它有可能成为早期识别和干预CSVD的成像生物标志物.

01:27Assessment of the Cardiovascular System III: Palpation
968
Palpation involves feeling the body to evaluate texture, size, consistency, and tenderness for assessing cardiovascular health. The following steps are organized in a head-to-toe order:
Jugular Venous Pressure (JVP) Measurement
Position the patient at a thirty- to forty-five-degree angle or in a semi-fowler's position. Look for the highest point of pulsation in the internal jugular vein and measure the vertical distance to the angle of Loius or sternal angle. A normal JVP is 3-4 cm above...

01:20Venous Thrombosis II: Clinical Manifestations and Diagnostic Studies
270
The key difference between Superficial Vein Thrombosis (SVT) and Deep Vein Thrombosis (DVT) lies in their location and severity.Clinical ManifestationsSVT typically presents with localized pain, tenderness, and redness along the course of a superficial vein, often accompanied by a palpable, cord-like structure under the skin. This condition is usually less dangerous than DVT but can be uncomfortable and may lead to complications such as cellulitis or, rarely, a clot extension into the deep...
