概括
人类母乳内分类素 (endocannabinoid) 概况在患有妊娠糖尿病 (GDM) 和没有妊娠糖尿病 (GDM) 的母亲之间有所不同. 这些介质的差异,如N-乙醇胺 (NAE) 与GDM暴露后代的婴儿生长有关.
科学领域:
- 人母奶的成分 人母奶的成分
- 内分泌学 在内分泌学.
- 代谢健康 代谢健康
背景情况:
- 内分类固醇和相关介质 (eCBome) 调节能量稳态,它们存在于母乳中.
- 暴露于妊娠糖尿病 (GDM) 的婴儿患肥胖的风险增加.
- 人母乳中的eCBome概况可能会影响婴儿发育和长期代谢健康.
研究的目的:
- 为了比较患有 (GDM+) 和没有 (GDM-) 妊娠糖尿病的妇女的牛奶中的eCBome介质配置文件.
- 评估乳 eCBome 组成和产后2个月后后代生长之间的关联.
- 调查GDM改变牛奶eCBome并影响婴儿生长的假设.
主要方法:
- 一项横截面研究测量了母乳中的eCBome介质 (n=53) 使用LC-MS/MS在分娩后2个月.
- 从有 (GDM+,n=24) 和没有 (GDM-,n=29) 妊娠糖尿病病史的妇女收集牛奶样本.
- 收集了婴儿的人类测量数据 (体重,身高),并计算了Z分数.
主要成果:
- 与GDM-妇女相比,GDM+妇女的牛奶中N-棕甲基乙醇胺 (PEA) 和几个2-单糖醇 (2-MAG) 的含量显著更高.
- 在GDM+母亲的婴儿中,N-乙醇胺 (NAE) 的水平,特别是非欧米茄-3 NAE,与体重与年龄的Z-分数有负相关性.
- 这些发现表明,GDM+牛奶中的eCBome概况发生了变化,与后代生长参数有关.
结论:
- 产后2个月母乳中的eCBome概况在有或没有GDM的妇女之间有所不同.
- 在GDM+母亲的乳 eCBome组成的变化与其后代的生长有关.
- 这些发现突出了母乳GDM,乳中介和婴儿代谢编程之间的潜在联系.

Pathophysiology of Diabetes
918
Diabetes mellitus is a chronic metabolic disorder characterized by hyperglycemia. The four categories of diabetes are type 1 diabetes, type 2 diabetes, other specific types of diabetes, and gestational diabetes.
Type 1 diabetes is characterized by autoimmune-mediated destruction of pancreatic β cells, with environmental factors potentially triggering this process in genetically susceptible individuals. Despite many not having a family history, certain genes increase susceptibility,...

Diabetes Mellitus: Type 2 and Gestational
2.3K
Type 2 diabetes, characterized by insulin resistance, arises when the insulin receptors on cells lose responsiveness to insulin, diminishing the cell's capacity to take up glucose, resulting in elevated blood glucose levels. To receive a diagnosis of Type 2 diabetes, a series of blood glucose tests are necessary to assess whether the blood glucose falls within normal parameters. If the result is out of the normal range, a patient may be diagnosed as prediabetic or diabetic, depending on the...
