概括
儿童早期的严重虐待显著改变了肠道微生物群,减少了其多样性和改变了细菌组成. 儿童肠道微生物组的这些变化可能会影响未来的精神和身体健康.
科学领域:
- 儿科健康 儿科健康
- 微生物组研究 微生物组研究
- 神经科学是一个神经科学.
背景情况:
- 大脑-肠轴至关重要,对早期生命中断非常敏感.
- 心理社会逆境会对肠道微生物组产生负面影响,影响健康.
- 早期的虐待是具有潜在健康后果的重大压力因素.
研究的目的:
- 为了研究小孩在遭受虐待后暴露的肠道微生物组合.
- 评估虐待严重程度与肠道微生物多样性和组成之间的关系.
主要方法:
- 88名儿童 (3至7岁) 通过使用"虐待分类的母亲采访 (MICM) "进行虐待评估.
- 儿童被分为没有,低,高虐待暴露组.
- 使用16S rRNA测序分析了便样本.
主要成果:
- 高度虐待暴露与显著降低肠道微生物α多样性有关 (辛普森指数).
- 两组之间没有观察到β多样性的显著差异.

71.4K
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...

252
Irritable Bowel Syndrome (IBS) is characterized by functional disturbances in the gastrointestinal system, presenting a cluster of symptoms without evident structural or biochemical abnormalities. It primarily affects the large intestine and may cause abdominal pain, bloating, excessive gas, diarrhea, constipation, or both.
IBS is a chronic condition that can persist over a long period or recur frequently.
The pathogenesis of IBS involves a complex interplay of the following factors:
