概括
系统性红斑狼 (SLE) 患者根据自身抗体配置文件有不同的心血管和静脉血栓栓塞的风险. 抗脂抗体 (aPL) 集群显示的风险最高,而自身抗体阴性集群的风险最低.
科学领域:
- 类风湿病学 类风湿病学
- 免疫学 免疫学 免疫学
- 心脏病学 心脏病学
背景情况:
- 系统性红斑狼 (SLE) 是一种自身免疫性疾病,具有不同的临床表现.
- 自体抗体简介对于理解SLE异质性和预测疾病结果至关重要.
- 心血管事件和静脉血栓塞栓症是SLE患者的重大疾病.
研究的目的:
- 在SLE患者中调查主要心血管事件 (MACE) 和静脉血栓栓塞 (VTE) 的发生率.
- 根据13个自身抗体,将SLE患者分为四个不同的群体.
- 为了在这些SLE自身抗体集群和匹配的对照中比较血管事件发生率.
主要方法:
- 一项前性队列研究,对461名SLE患者进行了12.2年的随访.
- 患者分为四个基线自身抗体集群:集群1 (抗SSA/SSB),集群2 (抗核体/Sm/RNP/dsDNA),集群3 (aPL) 和集群4 (自身抗体负).
- 通过国家患者登记册前性地检索血管结果 (MACE,VTE);用于对每个患者10个匹配的对照进行风险估计的Cox比例危险模型.
主要成果:
- 与基准集群相比,抗脂抗体 (aPL) 主导的集群 (集群3) 对MACE (HR 1.91) 和VTE (HR 2.69) 的相对风险最高.
- 集群2也显示心力衰竭和静脉动脉瘤的风险较高,与集群3相比,尽管患者年轻.
- 自体抗体阴性集群 (集群4) 在所有SLE集群中显示出血管事件发生率最低.
结论:
- 在SLE患者中,MACE和VTE发病率存在显著差异,这些患者根据自身抗体配置文件进行分类.
- 由aPL主导的集群与重大血管事件的最高风险有关.
- 自身抗体阴性SLE集群与最低的血管事件发生率有关,突出显示了自身抗体分析的预后价值.

Imaging Studies VII: Vascular Imaging
383
DefinitionRenal angiography, also known as renal arteriography, is an imaging technique used to obtain a comprehensive view of blood flow and the vascular structure of blood vessels in the kidneys and surrounding areas.PurposeRenal angiography detects blood vessel abnormalities in the kidneys, such as aneurysms, stenosis, thrombosis, vascular tumors, and renal artery stenosis. It evaluates kidney function and guides interventional treatments like angioplasty or stent placement.Pre-Procedure...

Defining Psychology
8.0K
Psychology is the scientific discipline dedicated to understanding both observable behavior and the internal mental processes underlying such behavior. It aims to comprehend human nature and apply this understanding to solve practical problems, enhance well-being, and improve societal outcomes. An example of psychology's application is the study of prosocial behavior, such as why and under what conditions individuals might help strangers in need. This process involves describing observed...

Cluster Sampling Method
14.8K
Appropriate sampling methods ensure that samples are drawn without bias and accurately represent the population. Because measuring the entire population in a study is not practical, researchers use samples to represent the population of interest.
To choose a cluster sample, divide the population into clusters (groups) and then randomly select some of the clusters. All the members from these clusters are in the cluster sample. For example, if you randomly sample four departments from your...

Vesicular Tubular Clusters
3.3K
After budding out from the ER membrane, some COPII vesicles lose their coat and fuse with one another to form larger vesicles and interconnected tubules called vesicular tubular clusters or VTCs. These clusters constitute a compartment at the ER-Golgi interface known as ERGIC (Endoplasmic Reticulum Golgi Intermediate Compartment). The ERGIC is a mobile membrane-bound cargo transport system that sorts proteins secreted from ER and delivers them to the Golgi.

Integration of Synaptic Events
4.2K
Synaptic integration mainly includes the summation of graded potentials. Graded potentials, regardless of their type, cause subtle alterations in membrane voltage, resulting in either depolarization or hyperpolarization. These incremental changes, when combined or summed, can propel the neuron toward its threshold. Consider, for example, a membrane experiencing a +15 mV shift, causing it to depolarize from -70 mV to -55 mV. In this scenario, graded potentials govern the membrane's ability to...
