概括
在心脏移植 (HT) 之前,将高级心力衰竭患者从体外膜氧化 (ECMO) 到其他机械循环支持装置 (MCSD) 的桥梁显示出与单独ECMO相比,相似的存活率和可能更短的住院时间.
科学领域:
- 心脏病学 心脏病学
- 移植医学 移植医学
- 医疗器械 医疗器械
背景情况:
- 在心脏移植 (HT) 之前,先进的心力衰竭和心脏性休克通常需要机械循环支持装置 (MCSD).
- 外体膜氧化 (ECMO) 经常用于立即稳定,但过渡到替代MCSD可能会改善患者在HT之前的结果.
- 以前的研究表明,仅依赖ECMO时,结果可能更差.
研究的目的:
- 为了研究心脏移植后的结果,从ECMO桥接到替代MCSDs的患者.
- 为了比较ECMO单独支持的患者与转移到其他MCSDs的患者之间的生存率和临床结果.
主要方法:
- 使用了联合器官共享网络 (UNOS) /器官采购和移植网络 (OPTN) 数据库.
- 在2018年至2024年间接受HT的已识别的成年患者 (≥18岁),在列表中需要ECMO.
- 将患者分为ECMO-only组和ECMO-to-MCSD组 (LVAD,RVAD,BiVAD,TAH);使用卡普兰-梅尔曲线和考克斯回归分析生存率.
主要成果:
- 在749名患者中,527名 (70%) 仅接受ECMO治疗. 30天,1年和5年的生存时间在ECMO-only和ECMO-to-MCSD组之间是可比的 (p=0.46).
- 与仅使用ECMO的患者相比,右心室辅助器 (RVAD) 患者的1年和5年生存率较低 (p=0.004).
- 排斥率,中风,透析和起器使用率在各组中相似;ECMO到MCSD的患者住院时间较短 (p=0.019).
结论:
- 从ECMO过渡到替代MCSD以弥合心脏移植并没有减少存活率或不良临床结果.
- 这种桥梁策略可以提供与仅ECMO支持的结果相似的结果,同时可能减少住院时间.

Anatomy of the Circulatory System
97.8K
The human circulatory system consists of blood, blood vessels that carry blood away from the heart, around the body, and back to the heart, and the heart itself, which acts as a central pump. The systemic circuit supplies blood to the whole body, the coronary circuit supplies blood to the heart, and the pulmonary circuit supplies blood flow between the heart and lungs.

Mechanisms of Membrane-bending
3.3K
The living membranes are flexible due to their fluid mosaic nature; however, their bending into different shapes is an active process regulated by specific lipids and proteins. The membrane bending can be transient as seen in vesicles or stable for a long time as in microvilli. Cells regulate the size, location, and duration of the membrane curvature.
Membrane bending can happen due to intrinsic changes in lipid composition or extrinsic association with different proteins. The proteins involved...

Design Example: Strain Gauge Bridge or Wheatstone Bridge
979
The utilization of strain gauges as transducers for converting mechanical strain into electrical signals is a common practice in various engineering applications. These strain gauges are frequently integrated into Wheatstone bridge circuits to accurately measure parameters such as force or pressure. Within this context, each element within the circuit exhibits a resistance that undergoes subtle variations when subjected to mechanical strain. The primary objective is to convert minuscule...

Mechanisms of Membrane Domain Formation
3.8K
Different physical properties of lipids and proteins allow them to localize and form distinct islands or domains in the membrane. Some membrane domains are formed due to protein-protein interactions, whereas others are formed due to the presence of specific lipids such as sphingolipids and sterols—for example, large proteins, such as bacteriorhodopsin, aggregate and create distinct domains.
Another mechanism for membrane domain formation involves membrane proteins interacting with...

Bridge rectifier
1.5K
The bridge rectifier is essential in electronics for efficiently converting alternating current (AC) to direct current (DC). Comprised of four diodes configured in a bridge layout, this rectifier effectively processes both the positive and negative halves of the AC waveform, making it superior to half-wave and full-wave center-tapped rectifiers in terms of voltage regulation and output stability.
Operationally, the bridge rectifier allows current flow through two of its diodes during each...

Wheatstone Bridge
1.2K
An ohmmeter is a resistance-measuring device. It works by applying a voltage to a resistor of unknown resistance and measuring the current across the resistor. The resistance value is deduced using Ohm's law. Usually, the standard configuration of an ohmmeter comprises a voltmeter or an ammeter. However, such configurations are limited in accuracy because the meters alter the voltage applied to the resistor and the current that flows through it.
Thus, for accurate resistance measurements, a...
