概括

一个稳定的,乳杆菌占主导地位的阴道微生物组与按时分娩有关. 在早产 (PTB) 病例中增加的微生物多样性表明早期PTB风险预测的潜在生物标志物.

科学领域:

微生物学微生物学
产科产科产科产科产科
公共卫生公共卫生

背景情况:

过早分娩 (PTB) 是新生儿发病率和死亡率的主要原因.
阴道微生物群 (VMB) 与PTB有关,但韩国女性的研究有限.
了解与PTB相关的VMB对于改善母亲和婴儿的结果至关重要.

研究的目的:

分析韩国妇女的终期和早产怀孕之间的VMB差异.
调查VMB组成和子宫长度 (CL) 之间的相关性.
为了确定潜在的微生物生物标志物用于早期PTB风险预测.

主要方法:

研究了一组60名韩国孕妇 (40名孕产妇,20名早产) 的队列.
阴道样本在整个怀孕期间和分娩后被纵向采集.
使用定量PCR分析VMB成分,并测量CL.

主要成果:

孕期产妇的怀孕显示出一个主要的Lactobacillus crispatus微生物群.
在早产孕中,微生物多样性更高,Prevotella唾液和Ureaplasma物种增加.
在PTB病例中宫长度缩短与改变的VMB组成相关.

结论:

一种稳定的,以乳杆菌为主导的VMB似乎对PTB有保护作用.
在PTB病例中增加的VMB多样性可以作为早期风险指标.
结合VMB分析和CL测量可以提高非侵入性PTB风险评估.

关键词:

宫的长度宫的长度纵向研究是一种纵向研究.过早分娩过早分娩是什么阴道的微生物群.

Anatomy of the Intestines

Anatomy of the Intestines

Although digestion of proteins, carbohydrates, and lipids may begin in the stomach, it is completed in the intestine. The absorption of nutrients, water, and electrolytes from food and drink also occurs in the intestine. The intestines can be divided into two structurally distinct organs—the small and large intestines.
Small Intestines
The small intestine is an ~7 meter-long tube with an inner diameter of just 2.5 cm. Since most nutrients are absorbed here, the inner lining of the...
