概括
甲基马龙酸 (MMA) 水平升高与细菌感染中败血症的发展有关. 然而,全转化胺 (HTC) 和总维生素B12 (B12) 水平与败血症风险没有显著关联.
科学领域:
- 生物化学 生物化学
- 免疫学 免疫学 免疫学
- 关键护理医学 关键护理医学
背景情况:
- 维生素B12表现出免疫调节作用,可能会影响败血症的病理生理学.
- 败血症是一种危及生命的器官功能障碍,是由宿主对感染的反应失调引起的.
研究的目的:
- 调查维生素B12状态标志物与细菌感染患者的败血症发展之间的关联.
- 为了比较holotranscobalamin (HTC),总维生素B12 (B12) 和甲基马龙酸 (MMA) 在患有败血症的患者和没有发生败血症的患者中的水平.
主要方法:
- 未来观察试点研究涉及99名患有细菌感染的成年患者.
- 这些测量包括HTC,B12和MMA水平.
- 使用后勤回归模型来评估与败血症发展的关联,调整为混因素.
主要成果:
- 在HTC或B12度和败血症发展之间没有发现显著的关联.
- 较高的MMA水平与患败血症的风险增加显著相关 (OR2.36,p=0.014).
- 经过对混因素进行调整 (OR 2.72,p=0.018) 后,这种关联仍然显著.
结论:
- 高MMA度与细菌感染患者的败血症发展有关.
- 在这个队列中,HTC和B12度与败血症风险无关.
- 需要进一步的研究,包括更大的研究和干预试验,以探索维生素B12补充剂在感染和败血症中的临床益处.

Factors Affecting the Risk of Infection
11.5K
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...

Pulmonary Tuberculosis I
227
Tuberculosis, often called TB, is a contagious illness primarily caused by Mycobacterium tuberculosis. It mainly affects the lung parenchyma but can also impact other body parts.
Causative Organism
The primary infectious agent causing tuberculosis is Mycobacterium tuberculosis, a slow-growing, acid-fast, aerobic rod that exhibits sensitivity to heat and ultraviolet light. Instances of Mycobacterium bovis and Mycobacterium avium contributing to the development of TB infection are rare.

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.
The best practices for preventing healthcare-associated infections include hand hygiene, patient risk...
