概括
这项研究发现,在治疗由黄金葡萄球菌,凝结酶阴性葡萄球菌或链球菌引起的周围假肢关节感染 (PJI) 中没有显著差异. 在PJI治疗中,交换手术对所有细菌类型的治疗似乎比DAIR更有效.
科学领域:
- 整形外科手术 整形外科手术
- 传染病 传染病 传染病
- 医学微生物学 医学微生物学
背景情况:
- 周围假肢关节感染 (PJI) 是部或膝盖关节整形术的严重并发症.
- 对于PJI的治疗难度因病原体而异,关于链球菌与葡萄球菌感染的争论仍在进行中.
- 这项研究比较了PJI的治疗结果,PJI是由 * Staphylococcus aureus * * 凝结酶阴性葡萄球菌 * (CoNS) 和 * 链球菌 * * 引起的.
研究的目的:
- 为了调查PJI的治疗结果是否根据引起病原体不同: *S. aureus*,CoNS或*Streptococci*.
- 为了比较由这些不同的细菌群体引起的PJI患者之间的无感染生存率.
- 评估手术方法 (DAIR与交换手术) 对PJI治疗结果的影响.
主要方法:
- 在1998年至2021年期间对299名PJI (部或膝盖) 患者进行了回顾性观察研究.
- 根据病原体对患者进行分类: *S. aureus* (114), CoNS (121), *Streptococci* (64).
- 使用Kaplan-Meier分析评估的无感染生存率;用于调整后复发风险分析的Cox回归.
主要成果:
- 三种细菌群体之间未经调整的存活率没有统计学上显著的差异.
- 两年没有感染的存活率:S. aureus*的71%;CoNS的75%,Streptococci*的60%.
- 调整后的复发危险比率在各组之间没有显著差异;在所有组中,交换手术的生存率比DAIR更好.
结论:
- 在这个队列中,链球菌PJI与葡萄球菌PJI相比没有表现出更困难的治疗结果.
- 交换手术似乎是一个比DAIR更有利的治疗策略PJI,无论引起病原体.
- 研究结果表明,PJI的治疗策略可能不需要针对病原体特异性,例如Staphylococci和Streptococci.

Factors Affecting the Risk of Infection
14.1K
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...

Healthcare Associated Infections I: Iatrogenic, Exogenic and Endogenic
5.7K
Healthcare-associated infections (HAIs) occur in a healthcare facility while a person receives care for another ailment. This category also includes work-related infections among healthcare staff.
HAIs significantly increase the cost of health care. Extended stays in healthcare institutions, increased disability, increased costs of medications, including specialized antibiotics, and prolonged recovery times add to the patient's expenses and the healthcare institution and funding bodies.

Healthcare Associated Infections II: Preventive Measures
4.7K
Essential infection prevention measures are based on the knowledge of the infection chain, the modes of transmission in healthcare settings, and the use of the best practices in all healthcare settings. Compulsory public reporting of healthcare-associated infection rates is needed to allow individuals and the community to make informed choices regarding selecting a healthcare facility.

Asepsis
3.7K
The condition of being free from disease-causing living pathogens is asepsis. Aseptic techniques include a set of standard practices to achieve asepsis. An example is the regular environmental cleaning of all parts of the healthcare facility and hand hygiene at home before preparing or eating food. Medical and surgical asepsis in healthcare practice protects patients from harmful pathogens, minimizes the risk of contamination of susceptible sites, and reduces the risk of infection transmission.

Staphylococcal Skin Infections
143
Staphylococcus aureus is a Gram-positive coccus that resides harmlessly on the skin and mucous membranes of healthy individuals. When the skin barrier is breached, it can shift from a commensal to an opportunistic pathogen. This transition is facilitated by surface adhesins, such as clumping factor B and S. aureus surface protein G (SasG), which bind to structural proteins, including loricrin and cytokeratin, in the damaged epidermis. Protein A, another key factor, binds the Fc region of...

Clinical Significance of Antibiotic Resistance
90
Methicillin-resistant Staphylococcus aureus (MRSA) presents a critical public health threat, arising from its capacity to resist β-lactam antibiotics due to acquisition of the mecA gene within the staphylococcal cassette chromosome mec (SCCmec). This gene encodes penicillin-binding protein 2a (PBP2a), which impairs binding efficacy of methicillin and other β-lactams. MRSA has evolved into distinct clonal lineages impacting humans and animals alike, reinforcing its significance within...
