概括
这项研究描述了在接受全关节整形手术 (TJA) 的患者中周围假肢微生物组的特征. 一个新的分类系统确定了四种不同的微生物群类型,有助于对周围假肢关节感染 (PJI) 的诊断.
科学领域:
- 微生物学 微生物学
- 整形外科手术 整形外科手术
- 基因组学就是基因组学.
背景情况:
- 周围假肢关节感染 (PJI) 是全面关节整形术 (TJA) 后的一种严重并发症.
- 在TJA之后,围围假肢环境的微生物组还没有得到很好的描述.
- 了解这种微生物群对于诊断和管理PJI至关重要.
研究的目的:
- 在怀疑PJI的患者中,使用元基因组下一代测序 (mNGS) 探索周围假肢微生物群.
- 开发一个对周围假肢微生物群的分类系统.
- 为了将微生物群类型与临床PJI指标相关联.
主要方法:
- 一项前性研究涉及28名培养阳性PJI,14名培养阴性PJI和35名非PJI患者.
- 共同的愿望,然后是无目标的mNGS和生物信息学分析.
- 开发和外部验证基于RandomForest的微生物群"分类系统".
主要成果:
- 周围假肢微生物组在PJI和非PJI组之间存在显著差异.
- 确定了四种一般的微生物群类型:"葡萄球菌"",伪冠状病毒"",Escherichia"和"Cutibacterium".
- "葡萄球菌"和"伪马氏菌"类型与较高的炎症有关,并证实了PJI,与葡萄球菌spp. 与炎症标志物相关联. 炎症标志物与炎症标志物相关联.
结论:
- 这项研究提供了TJA.之后第一次对周围假肢环境微生物群的表征.
- 使用RandomForest模型建立了一个基本的微生物群"分类系统".
- 这种分类系统可以作为未来PJI研究和诊断的参考.

Inflammatory Response II: Inflammatory Exudate and Tissue Repair
5.1K
The immune system's inflammatory response destroys the invading pathogen, permitting the tissue to heal. The changes during the cellular and vascular stages allow exudate formation at the site of inflammation. The inflammatory exudate released from the wound has high protein content and a specific gravity above 1.020.
The typical wound exudate is odorless, transparent, straw-colored, thin, and watery. Exudate, however, can differ depending on the state of wound healing. Likewise, the...

Factors Affecting the Risk of Infection
12.0K
The hosts' susceptibility to infection depends on several factors. The integrity of the skin and mucous membranes helps protect the body against microbial attacks. When the skin is altered, the chance of infection, limb loss, and even death increases.
The integrity and count of the white blood cells help the body resist pathogens and fight infection. When impaired, it reduces the body's resistance to pathogens. The acidic pH levels of the gastrointestinal, genitourinary tracts, and skin...

Inflammatory Response
2.2K
An inflammatory response is a localized, nonspecific immune reaction that occurs when a tissue is injured. It is characterized by redness, swelling, heat, and pain, which are commonly called the cardinal signs and symptoms of inflammation. Inflammation can sometimes result in a loss of function.
Inflammation can be triggered by various stimuli, such as impact, abrasion, chemical irritation, infections, and extreme hot or cold temperatures. These can damage cells and connective tissue fibers,...

Inflammatory Bowel Disease II: Crohn's Disease

Introduction
Inflammatory bowel disease, commonly known as IBD, refers to a collection of disorders that lead to persistent inflammation of the gastrointestinal tract. The two types of IBD are ulcerative colitis, which impacts the colon, and Crohn's disease, which can involve any part of the gastrointestinal segment.
Crohn's disease
Crohn's disease is a chronic, systemic inflammatory bowel disease (IBD) that predominantly affects the gastrointestinal tract. It is marked by...

Endocarditis I: Introduction
13
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...
