概括
在感染性内心炎手术中用于假肢固定的自动化紧固件显示,与手工绑定的结节相比,再次内心炎的风险明显较低. 这种新的方法似乎是安全的,尽管需要进行更大的研究.
科学领域:
- 心血管外科心血管外科
- 生物医学工程 生物医学工程
- 传染性疾病 传染性疾病
背景情况:
- 传染性内心炎需要手术干预,通常涉及假肢固定.
- 目前的标准做法是使用手工捆绑的结,对替代方法的数据有限.
- 在这种情况下,用于固定假肢的自动紧固件的安全性和有效性尚未得到充分证实.
研究的目的:
- 为了比较自动化紧固件的安全性和有效性与手工绑定的节点用于假肢固定,在接受感染性内心炎手术的患者中.
- 评估再次内心炎,中风,全因死亡率的风险,以及两种固定方法之间的复合结果.
主要方法:
- 在2016年1月至2022年12月期间,对220名因感染性内心炎接受手术的患者进行了回顾性分析.
- 患者被分为两组:自动固定紧固件 (n=114) 和手动固定结 (n=106).
- 统计分析包括多变量比例竞争风险回归,Cox比例危险回归和Poisson回归来评估结果.
主要成果:
- 自动紧固件组表现出明显较低的再次内心炎的风险 (调整后的次危险比为0.33,p=0.048).
- 在自动化紧固件组中,没有明显增加中风风险,复合结果或全因死亡率.
- 对中风和复合结果的调整后危险比分分别为0.54 (p=0.082) 和0.65 (p=0.061). 所有原因死亡率的调整后发病率比为1.42 (p=0.202).
结论:
- 在感染性内心炎手术中,自动化紧固件设备的使用似乎是安全的,用于假肢固定.
- 这项研究表明,降低复发性内心炎的发生率可能有所益处.
- 建议对更大的患者队伍进行进一步的研究,以证实这些发现.

Steel Fastening Techniques
1.4K
Steel sections can be joined together through various fastening techniques including riveting, bolting, and welding, each suitable for different structural requirements and conditions.
Rivets are cylindrical steel fasteners with a specially designed head. During application, rivets are heated until white-hot and then inserted through pre-drilled holes in the steel sections. A pneumatic hammer is used to shape the exposed end into a second head, securing the sections together.
Bolting is another...

Endocarditis I: Introduction
822
Introduction:Endocarditis is the infection of the endocardium, the inner lining of the heart and its valves. When the heart muscle is involved, the condition is termed myocarditis, while an infection of the outer lining is called pericarditis. Infective endocarditis (IE) primarily affects the endocardium, where pathogens adhere to the valves or lining, forming vegetation that can lead to severe complications. Infective endocarditis occurs when microorganisms, usually bacteria from other body...
