概括
一种新的带的抗迁移支架 (AMS) 与用于远端恶性胆道阻塞的常规支架 (CS) 相比,其原始迁移率较低. 然而,经过调整的分析并未证实支架迁移的统计显著减少.
科学领域:
- 胃肠病学和肝病学
- 干预性内镜检查是干预性的内镜检查.
- 胆汁干预 胆汁干预
背景情况:
- 远端恶性胆道阻塞 (dMBO) 通过使用完全覆盖的自扩展金属支架 (FCSEMS) 来缓解.
- 支架迁移是FCSEMS在dMBO管理中的一个重要限制.
- 一个新的反迁移FCSEMS (AMS) 设计旨在减少与传统的发火FCSEMS (CS) 相比的迁移.
研究的目的:
- 在dMBO患者中比较AMS与CS的迁移率和疗效.
- 评估两种支架类型之间复发性胆道阻塞 (RBO) 的风险.
主要方法:
- 对于在2020年4月至2024年4月期间接受ERCP的未切除dMBO的成年人进行回顾性队列研究.
- 患者接受的是AMS或CS.
- 支架迁移和RBO是主要结果,使用治疗权重的逆概率 (IPTW) 考克斯模型和倾向得分匹配 (PSM) 进行分析.
主要成果:
- 与CS组 (7.6%;p=0.02) 相比,AMS组 (0.96%) 的原始迁移率明显较低.
- 在IPTW调整后,AMS的迁移风险降低没有统计学意义 (HR 0.23;p=0.16).
- 在PSM后的AMS中,迁移数量仍然较低 (p=0.10),而RBO风险在各组之间是可比的.
结论:
- 芬兰的反移民FCSEMS在dMBO息中显示出与传统支架相比,减少移民的趋势.
- 虽然原始迁移较低,但调整后的分析没有达到减少迁移的统计学意义.
- 两种类型的支架都显示出类似的通透率,涉及到复发性胆道阻塞.

Metallic Solids

Metallic solids such as crystals of copper, aluminum, and iron are formed by metal atoms. The structure of metallic crystals is often described as a uniform distribution of atomic nuclei within a “sea” of delocalized electrons. The atoms within such a metallic solid are held together by a unique force known as metallic bonding that gives rise to many useful and varied bulk properties.
All metallic solids exhibit high thermal and electrical conductivity, metallic luster, and malleability....

Bonding in Metals

Metallic bonds are formed between two metal atoms. A simplified model to describe metallic bonding has been developed by Paul Drüde called the “Electron Sea Model”.

Molecular Comparison of Gases, Liquids, and Solids

Particles in a solid are tightly packed together (fixed shape) and often arranged in a regular pattern; in a liquid, they are close together with no regular arrangement (no fixed shape); in a gas, they are far apart with no regular arrangement (no fixed shape). Particles in a solid vibrate about fixed positions (cannot flow) and do not generally move in relation to one another; in a liquid, they move past each other (can flow) but remain in essentially constant contact; in a gas, they move...

Sign Convention

When analyzing a beam subjected to various loads, it is crucial to understand the internal forces and moments generated within the structure. These internal forces can be broadly classified into normal forces, shear forces, and bending moments. To determine these forces and moments, we use the method of sections and apply a specific sign convention based on their direction and the side of the section being analyzed.
The normal force acts perpendicular to the beam's cross-section and can...

The Sense of Self: Reflected Self-Appraisal and Social Comparison

According to Charles Cooley, we base our image on what we think other people see (Cooley 1902). We imagine how we must appear to others, then react to this speculation. We don certain clothes, prepare our hair in a particular manner, wear makeup, use cologne, and the like—all with the notion that our presentation of ourselves is going to affect how others perceive us. We expect a certain reaction, and, if lucky, we get the one we desire and feel good about it. But more than that, Cooley...

Lattice Centering and Coordination Number

The structure of a crystalline solid, whether a metal or not, is best described by considering its simplest repeating unit, which is referred to as its unit cell. The unit cell consists of lattice points that represent the locations of atoms or ions. The entire structure then consists of this unit cell repeating in three dimensions. The three different types of unit cells present in the cubic lattice are illustrated in Figure 1.
