背景情况:
- 在修复全关节整形术 (rTHA) 后,Cutibacterium物种在周围假肢关节感染 (PJI) 和意外阳性手术内培养 (UPIC) 中的作用尚未完全理解.
- 关于Cutibacterium avidum与Cutibacterium acnes的比较流行率,临床结果和微生物特征的数据有限.
研究的目的:
- 调查和比较与Cutibacterium avidum和Cutibacterium acnes相关的rTHA病例中的临床结果和相关因素.
主要方法:
- 分析了来自564名患者的636例培养阳性rTHA病例 (2011-2021年),至少进行40个月的随访.
- 对C. avidum和C. acnes的临床表现,风险因素,感染类型 (PJI与UPIC) 和抗生素耐药性的评估.

01:27The Skin Microbiota
The human skin serves as a complex ecosystem inhabited by a diverse community of microorganisms, including bacteria, fungi, and viruses. This microbiome plays a critical role in maintaining skin health and defending against pathogenic invaders. The composition of microbial communities varies significantly across different regions of the body, influenced primarily by the local levels of moisture and sebum.Regional Variation in Skin MicrobiotaCutibacterium acnes predominantly colonizes sebaceous...
01:22Microbiome of the Eye
The human eye has a specialized microbiota that reflects its unique anatomical and immunological environment. This low-biomass microbial community predominantly colonizes the conjunctiva and eyelid margins, playing a vital role in ocular surface homeostasis and defense. Despite its proximity to the richly colonized facial skin, the ocular surface maintains a distinct microbial profile due to continuous mechanical and biochemical defense mechanisms.The conjunctival surface hosts fewer microbial...
01:27Acne Infection
Acne is a multifactorial skin condition primarily affecting adolescents and young adults, with a global prevalence estimated to exceed 75% in this demographic. The condition is characterized by the formation of comedones (blackheads and whiteheads), papules, pustules, nodules, and, in severe cases, cysts, particularly in areas rich in sebaceous glands such as the face, neck, chest, and back. The pathogenesis involves increased sebum production, follicular hyperkeratinization, colonization by...
