概括
与单个SR相比,双支柱回收器 (SR) 技术在中风血栓切除术中显著改善了第一通道回管治疗. 虽然它是安全的,但它没有在实现最终的再通道化方面表现出优越性,因此需要进一步的临床结果研究.
科学领域:
- 神经学 神经学
- 干预性神经辐射学
- 心血管疾病 心血管疾病
背景情况:
- 双支支架检索器 (SR) 技术在单支架失败时被公认为血栓切除术的救援策略.
- 这项研究评估了使用双SR技术作为中风的主要治疗方法的安全性和有效性.
研究的目的:
- 评估双支支架检索器 (SR) 技术作为中风血栓切除术的第一线方法的有效性.
- 为了比较单个SR和双SR技术之间的第一通道再通道率.
- 评估双重SR技术的安全性,特别是症状性脑内出血的发生率.
主要方法:
- 一个多中心的,随机的,受控的,盲目的结局研究包括在24小时内发生大血管封闭性中风的患者.
- 患者被随机分配到单SR或双SR的第一线策略中.
- 疗效是通过一次通完整的再通道 (eTICI 2c-3) 来定义的;安全性是通过症状性脑内出血来评估的.
主要成果:
- 双SR组的患者中有46%的患者实现了第一通复通,而单SR组的患者只有24% (aOR,2.72).
- 在3次试验内,实质性的再输血在各组之间是相似的 (89%的双SR与84%的单SR).

Comparing Copy Number Variations and SNPs
Sequencing of the human genome has opened up several best-kept secrets of the genome. Scientists have identified thousands of genome variations that exist within a population. These variations can be a single nucleotide or a larger chromosomal variation.
Copy number variations or CNVs are the structural variations that cover more than 1kb of DNA sequence. The single nucleotide polymorphism (SNP), on the other hand, is a single nucleotide change or a point mutation that is found in more than 1%...

Multiple Comparison Tests
Multiple comparison test, abbreviated as MCT, is a post hoc analysis generally performed after comparing multiple samples with one or more tests. An MCT will help identify a significantly different sample among multiple samples or a factor among multiple factors.
It would be easy to compare two samples using a significance alpha level of 0.05. In other words, there is only one sample pair to be compared. However, it would be difficult to identify a significantly different sample if the number...

Randomized Experiments
The randomization process involves assigning study participants randomly to experimental or control groups based on their probability of being equally assigned. Randomization is meant to eliminate selection bias and balance known and unknown confounding factors so that the control group is similar to the treatment group as much as possible. A computer program and a random number generator can be used to assign participants to groups in a way that minimizes bias.

Wald-Wolfowitz Runs Test I
The Wald-Wolfowitz test, also known as the runs test, is a nonparametric statistical test used to assess the randomness of a sequence of two different types of elements (e.g., positive/negative values, successes/failures). It examines whether the order of the elements in a sequence is random or if there is a pattern or trend present. This nonparametric test applies to any ordered data despite the population and sample data distribution, even if a higher sample size is available.

Wald-Wolfowitz Runs Test II
The Wald-Wolfowitz runs test, commonly referred to as the runs test, is a nonparametric test used to assess the randomness of ordered data. The test evaluates the number of runs, which are consecutive sequences of similar elements within the data. If the number of runs is significantly higher or lower than expected, the data is considered non-random, indicating a detectable pattern or structure.
For binary data, runs are identified using symbols such as + and −, or equivalently, 1s and 0s. In...

Multimachine Stability
Multimachine stability analysis is crucial for understanding the dynamics and stability of power systems with multiple synchronous machines. The objective is to solve the swing equations for a network of M machines connected to an N-bus power system.
In analyzing the system, the nodal equations represent the relationship between bus voltages, machine voltages, and machine currents. The nodal equation is given by:
