概括
抗菌素耐药性 (AMR) 导致英国一家医院4.2%的死亡,死亡证明报告不足. 内在抗药性机制在AMR引起的死亡率中与获得的抗药性机制同样重要.
科学领域:
- 临床医学 临床医学
- 传染性疾病 传染性疾病
- 公共卫生 公共卫生
背景情况:
- 估计抗菌素耐药性 (AMR) 对死亡率的患者水平影响是复杂的.
- 这项研究旨在量化英国一家主要的教学医院中AMR引起的死亡.
- 了解AMR在死亡率中的作用对于公共卫生战略至关重要.
研究的目的:
- 在患者层面描述因抗菌素耐药性 (AMR) 而导致的死亡.
- 评估内在与获得性抗药性机制对抗药性耐药性归因死亡率的贡献.
- 评估死亡证明在反映AMR作为死亡原因时的准确性.
主要方法:
- 在英国一家教学医院2022年所有已故患者的回顾性分析.
- 两名调查人员对患者记录进行独立审查,使用一种新的AMR归因死亡的患者层面定义.
- 分析耐药机制 (内在与获得) 和有效治疗的时间.
主要成果:
- 抗菌素耐药性 (AMR) 被确定为4.2%的所有死亡的原因或贡献因素 (32/758).
- 内在的耐药性机制 (例如,Enterococcus faecium,带有AmpC的肠杆菌,Pseudomonas aeruginosa) 是导致大多数AMR死亡的原因.
- 在死亡证明上,感染的报道显著不足;在任何情况下,AMR都没有被记录为死亡原因.
结论:
- 感染和AMR是导致死亡的重要因素,但在死亡证明中经常被低估.
- 在抗菌素耐药性发病率较低的环境中,内在耐药性在抗菌素耐药性导致的死亡率中起着至关重要的作用,与获得性耐药性相比.
- 在死亡证明上准确记录感染和AMR对于了解它们对公共健康的真正影响至关重要.

Antimicrobial Effectiveness
The effectiveness of antimicrobial agents depends on various factors influencing their ability to eliminate microbial populations. Larger microbial populations require more time for complete eradication, emphasizing the importance of population size analysis when evaluating antimicrobial efficacy.Microbial resistance to antimicrobial agents varies significantly. Highly resilient microorganisms include endospores, gram-negative bacteria, and non-enveloped viruses, while prions are exceptionally...
Development of Antibiotic Resistance
Antibiotic resistance is a major public health concern that arises when bacteria evolve mechanisms to withstand the effects of antibiotic treatments. This resistance can be intrinsic, acquired through genetic mutations, or transferred between bacteria via horizontal gene transfer. The development of antibiotic resistance poses significant challenges in treating bacterial infections and necessitates ongoing research to develop new therapeutic strategies.Intrinsic resistance occurs when bacterial...
Genomic DNA in Prokaryotes
43.4K
The genome of most prokaryotic organisms consists of double-stranded DNA organized into one circular chromosome in a region of cytoplasm called the nucleoid. The chromosome is tightly wound, or supercoiled, for efficient storage. Prokaryotes also contain other circular pieces of DNA called plasmids. These plasmids are smaller than the chromosome and often carry genes that confer adaptive functions, such as antibiotic resistance.
