概括
在剖腹产期间服用抗生素的时间显示对婴儿肠道微生物群的影响有限. 养方式,而不是抗生素的使用,是塑造婴儿肠道微生物组成的主要因素.
科学领域:
- 微生物学 微生物学
- 儿科 儿科 儿科
- 产科 产科 产科 产科 产科
背景情况:
- 剖腹产 (CS) 出生在全球范围内很常见.
- 在CS期间皮肤切口前,抗生素预防是标准实践,以预防母亲和婴儿感染.
- 抗生素定时对发育中的婴儿肠道微生物群的影响尚未完全理解.
研究的目的:
- 调查剖腹产 (剖腹产) 期间抗生素施用时间对婴儿肠道微生物群的影响.
- 为了比较切口前与带紧后抗生素对婴儿微生物组成和功能的影响.
主要方法:
- 一项随机对照试验 (NCT06030713) 涉及女性接受计划性CS.
- 婴儿在皮肤切割前或带紧后都接受了抗生素.
- 婴儿肠道微生物组的纵向 (172个样本,28名婴儿,8个时间点) 和横截面 (79名婴儿,1个月) 分析.
主要成果:
- 在抗生素服用时间组之间,没有观察到细菌组成,代谢途径,短链脂肪酸或胆汁酸的显著差异.
- 在细菌菌株水平和抗生素耐药性基因负载上发现了微妙的差异.
- 婴儿养模式成为影响微生物组成的主要因素.
结论:
- 在剖腹产期间服用抗生素的时间对生命早期的婴儿肠道微生物群的影响很小.
- 养方式是婴儿肠道微生物发育的更重要的决定因素,而不是抗生素预防的时间.
- 进一步的研究可能会探索菌株水平和抗生素耐药性基因动态.

Anatomy of the Intestines
71.6K
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...

Surface Membrane Barriers
1.1K
The skin and mucous membranes serve as the primary line of defense against pathogens by providing both physical and chemical protection. These barriers are essential in preventing the entry and establishment of microbes, thereby maintaining the integrity of the host.
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...
