概括
剪切波弹性图 (SWE) 在狼性炎 (LN) 患者中检测出亚临床损伤,即使在缓解期. 这种非侵入性工具对监测系统性红斑狼 (SLE) 慢性损伤具有前景.
科学领域:
- 腎臟病學 (nephrology) 是一種醫學專業.
- 类风湿病学 类风湿病学
- 医疗成像医学成像
背景情况:
- 狼性炎 (LN) 是系统性狼发疹 (SLE) 的严重并发症,需要除活检外的非侵入性监测方法.
- 亚临床损伤,特别是纤维化,即使在临床缓解期间,SLE患者也可能在临床缓解期间持续存在,影响长期结果.
- 目前的非侵入性工具,如多普勒超声波 (DUS),可能无法充分捕捉脏中的慢性纤维化变化.
研究的目的:
- 评估剪波弹性图 (SWE) 的诊断实用性,用于检测临床下纤维化在SLE患者的诊断实用性,具有临床缓解期的LN病史.
- 为了比较SWE与多普勒超声波 (DUS) 在识别本患者队列中的关节细胞变化的有效性.
- 评估SWE测量的硬度与功能和疾病活动的已确定的标志物之间的相关性.
主要方法:
- 一项涉及80名SLE患者 (37名先前患有LN,43名没有) 临床缓解 (SLEDAI-2K < 6) 和41名健康对照者的横截面研究.
- 用SWE (以kPa) 测量膜硬度,用DUS评估抗性指数 (RI).
- 排除标准被应用以排除非SLE并发症;SWE发现与功能测试和疾病活性得分相关联.
主要成果:
- 与非LN SLE患者 (1.40 kPa) 和健康对照患者 (1.32 kPa) (p < 0.001) 相比,有LN病史的SLE患者表现出明显更高的硬度 (中位数: 1.60 kPa).
- 在非LN SLE患者和对照人群 (p > 0.05) 之间没有发现硬度的显著差异.
- 来自DUS的脏RI值在组之间没有统计学上显著的差异 (p > 0.05),与SWE不同.
- 硬度与先前的血清肌素和SLEDAI-2K得分正相关,与估计的淋巴细胞过率 (eGFR) 负相关.
结论:
- 在检测狼性炎患者慢性关膜细胞变化方面,SWE优于DUS (RI).
- 在不活跃疾病期间硬度升高表明SWE检测到累积纤维性损伤而不是急性炎症.
- 在SLE患者中,SWE显示出作为一种非侵入性的替代标记物,用于监测SLE患者的疾病慢性和累积损伤的潜力.

The Wave Nature of Light
61.7K
The nature of light has been a subject of inquiry since antiquity. In the seventeenth century, Isaac Newton performed experiments with lenses and prisms and was able to demonstrate that white light consists of the individual colors of the rainbow combined together. Newton explained his optics findings in terms of a "corpuscular" view of light, in which light was composed of streams of extremely tiny particles traveling at high speeds according to Newton's laws of motion.

Shear Diagram
1.7K
In the study of beam mechanics, shear diagrams play a crucial role in understanding the distribution of shear forces along the length of a beam. Consider a beam AB that is supported at both ends and subjected to perpendicular loads.
First, a free-body diagram of the beam is drawn, representing all the external forces and internal reactions acting on the beam. One can calculate the reaction forces at each support by employing the equilibrium equations of force and moment. The vertical component...

Shearing Stress
2.0K
Shearing stress, denoted by the Greek letter tau (τ), is stress caused by forces acting transversely on an object. These forces create internal ones within the entity in the plane where the external forces are applied. The resultant of these internal forces is the shear in the section.
The average shearing stress can be calculated by dividing the shear by the area of the cross-section.

Shearing Strain
1.5K
The shearing strain represents a cubic element's angular change when subjected to shearing stress. This type of stress can transform a cube into an oblique parallelepiped without influencing normal strains. The cubic element experiences a significant transformation when exposed solely to shearing stress. Its shape alters from a perfect cube into a rhomboid, clearly demonstrating the effect of shearing strain. The degree of this strain is considered positive if it reduces the angle between the...

Factors Affecting Renal Clearance: Renal Impairment
485
Renal dysfunction significantly impairs the renal clearance of drugs, leading to potential complications in drug therapy. Renal failure, which can be caused by various factors, poses a significant challenge in the elimination of drugs from the body.
One condition associated with renal failure is uremia. Uremia is characterized by impaired glomerular filtration and fluid accumulation in the body. This condition hinders the renal clearance of drugs, resulting in drug accumulation and potential...

Normal and Shear Force
3.4K
When a beam is subjected to different loads, such as weight, pressure, or other external forces, internal forces are generated within the beam. These forces can have a significant impact on the overall stability and strength of the structure. Engineers use various methods to analyze and determine the magnitude and direction of these internal forces. One common technique used to determine internal forces in beams is the method of sections. This method involves considering an imaginary point or...
