皮肤对皮肤 (STS) 护理丰富了早产婴儿的微生物组. 增加STS暴露对垂直微生物传播产生积极影响,调节口腔和肠道微生物平衡,改善婴儿肠道健康.
科学领域:
- 微生物学 微生物学
- 新生儿医学 新生儿医学
- 微生物组研究 微生物组研究
背景情况:
- 皮肤对皮肤 (STS) 护理因其对早产婴儿的益处而得到认可.
- STS护理可能会促进母婴垂直微生物传播.
- 丰富早产婴儿的微生物组是STS护理的潜在结果.
研究的目的:
- 调查皮肤对皮肤 (STS) 护理持续时间增加对垂直微生物传播的影响.
- 确定STS护理如何调节早产婴儿的口腔和肠道微生物平衡.
- 定义STS暴露和微生物群落组成之间的关系.
主要方法:
- 涉及产后妇女和早产婴儿 (31-34周妊娠期) 的观察性研究.
- 16S rRNA测序用于分析母体皮肤,婴儿口腔和婴儿便中的微生物群落.
- 微生物多样性 (α-和β-多样性) 和相对丰度在低 (<40分钟) 和高 (>60分钟) STS暴露组之间的比较.
主要成果:
- 微生物的组成,多样性和丰度在母体皮肤,婴儿口腔和婴儿便样本中显著不同.
- 高STS暴露的早产婴儿显示口腔微生物丰富度降低,但便丰富度增加.
- 观察到口腔和肠道微生物多样性和组成的显著差异,特定的属 (Gemella,Aggregatibacter) 和一个家族 (Lachnospiraceae) 在高STS组的便中更为丰富.
结论:
- 皮肤对皮肤 (STS) 护理似乎是增强早产婴儿微生物群落的有效策略.
- 增加STS护理持续时间会影响垂直微生物传播和婴儿微生物组的发展.
- 研究结果支持使用STS护理来促进脆弱的早产人口中更强大的微生物群.

Surface Membrane Barriers
The outer layer of the skin, the epidermis, is a robust barrier comprising layers of closely packed keratinized cells. This dense arrangement prevents microbes from penetrating the body. The periodic shedding of epidermal cells...
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...
Development of Immunocompetence
The initial cells that migrate from the fetal thymus settle within the skin and epithelial tissues lining the mouth, digestive tract, and in females, the uterus and vagina. These cells, including skin-based dendritic cells, serve as antigen-presenting cells, playing a key role in T cell activation.
Subsequent T...
