在老年护理居民中,肠道微生物组不能预测尿路感染 (UTI). 高度使用抗生素和与年龄相关的因素可能会掩盖潜在的联系,这表明老年人的尿路感染可能独立于肠道微生物群.
科学领域:
- 微生物学 微生物学
- 老年学是一门学科.
- 传染性疾病 传染性疾病
背景情况:
- 尿路感染 (UTI) 在长期护理中很常见,可能导致严重结果的风险,如尿路感染.
- 肠道病原生物转移被认为是大多数尿路感染的原因.
- 在年轻人中,肠道微生物群和尿路感染风险之间的联系是已知的,但在老年人中不确定.
研究的目的:
- 调查肠道微生物组组成和长期老年护理居民的尿路感染发病率之间的关联.
- 为了比较有或没有尿路感染史的老年护理居民和年轻成年人的微生物特征.
- 探索抗生素暴露和其他健康因素对老年人尿路感染风险的影响.
主要方法:
- 对54名长期老年护理人员进行了便微生物组分析,其中54人有尿路感染史,69人没有.
- 在老年护理居民和20名没有尿路感染的年轻成年人之间比较了微生物组数据.
- 检查了微生物组特征与之前/随后的尿路感染和抗生素治疗有关.
主要成果:
- 之前的尿路感染史或尿路感染专用抗生素对老年护理居民的肠道微生物群没有显著影响.
- 与尿路感染治疗无关的抗生素与独特的微生物群特征有关.
- 经过对痴呆症,失禁,糖尿病和先前使用抗生素进行调整后,没有特定的肠道微生物群特征与尿路感染发展有关.
- 以前的尿路感染史预测了未来的尿路感染.
- 与年轻的成年人相比,老年护理居民显示出更大的微生物群变异性,更低的多样性和改变的功能潜力.
结论:
- 肠道微生物组与长期老年护理居民的尿路感染发病率无关,与年轻人不同.
- 高度的抗生素暴露和与年龄相关的因素可能会掩盖老年人潜在的微生物和尿路感染的关联.
- 老年人中尿路感染风险增加可能独立于肠道微生物组介导的机制.

Factors Affecting the Risk of Infection
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
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.
Defense Mechanism Against Infection
In addition, many body organ systems have unique defenses against infection. The skin is an intact, multilayered surface preventing invasion by microorganisms unless impaired. Mucous membranes lining the mouth, nose, and eyelids are barriers...
