概括
血液感染 (BSI) 的死亡往往是由于潜在的疾病,而不仅仅是感染本身. 这项研究强调了需要新的策略来预防BSI并改善患者的治疗结果.
科学领域:
- 传染性疾病 传染性疾病
- 流行病学 流行病学
- 公共卫生 公共卫生
背景情况:
- 血流感染 (BSI) 是死亡的重要原因.
- 随着BSI死亡的主要原因,无论是感染相关的还是由于伴随疾病,都需要澄清.
研究的目的:
- 确定四种常见的BSI病原体的总死亡率,可归因于感染的死亡率和死亡原因.
- 为了比较与*大肠杆菌*,*克莱布西埃拉*种类,*假菌*和*金黄色葡萄球菌*BSI相关的死亡率.
主要方法:
- 使用英国电子健康记录 (2010-2022) 的回顾性队列研究.
- 包括成年人患有*大肠杆菌*,*克莱布西拉*种类,*P. aeruginosa*和*S. aureus*的BSI.
- 分析了使用考克斯回归和竞争风险模型的30天全因和败血症特定死亡率.
主要成果:
- *P. aeruginosa* BSI与最高的30天死亡率 (HR 1.96) 有关.
- 癌症是BSI后死亡的主要原因,特别是在30-90天 (35.9%) 之间.
- 败血症占30天死亡人数的25.5%;耐甲基黄金菌 (MRSA) 的败血症死亡率更高 (HR 2.56).
结论:
- 大多数BSI死亡不仅仅是由于不受控制的感染,特别是在亚急性阶段 (>30天).
- 这些发现表明,需要重新评估BSI的临床试验设计.
- 改善BSI的预防策略至关重要.

Factors Affecting the Risk of Infection
11.8K
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
4.2K
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
2.6K
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.

Infection
7.9K
When a pathogen enters the body and reproduces, it can cause an infection, damage body cells, and cause illness symptoms that eventually lead to disease. Therefore, its prevention requires breaking the chain of infection.
The chain begins with pathogens: bacteria, viruses, fungi, prions, or parasites such as protozoa helminths. These can be present on the skin as transient or resident flora, or they can be acquired from the environment. Identifying and treating the type of infection and...

Pneumonia I: Introduction
226
Pneumonia is an acute respiratory infection that targets the lungs, specifically the alveoli. These tiny air sacs, essential for oxygen exchange, become engorged with pus and fluid, severely hindering breathing, decreasing oxygen absorption, and causing significant pain and discomfort during respiration.
Risk Factors
Various factors influence the likelihood of developing pneumonia. Age plays a crucial role, with infants, children under two, and individuals over 65 at increased risk due to their...

Stages of Infection
56.3K
Stages of infection describe what happens to a susceptible host once a pathogen invades the human body. The stages of infection are incubation, prodromal, illness, stage of decline, and convalescence. The incubation stage is the period from exposure to a pathogen until symptoms start. The infected person is unaware of impending illness as the pathogens grow and multiply within the body. The duration may vary depending on the type of infection. The incubation period of measles averages ten to...
