概括
胎儿生长限制 (FGR) 和长期的上多普勒异常可能会增加早产婴儿肠道疾病 (ID) 的风险. 压力大的子宫内环境可能会导致产后肠道脆弱性增加.
科学领域:
- 新生儿医学 新生儿医学
- 产周研究 产周研究
- 儿科手术 儿科手术
背景情况:
- 肠道疾病 (ID) 显著影响早产婴儿,诸如死性肠球炎 (NEC),与相关的阴茎 (MRI) 和焦点肠道穿孔 (FIP) 等疾病构成重大挑战.
- 虽然已知特定ID的个体风险因素,但早产婴儿ID的整体病因仍然不完全理解.
- 识别总体产科风险因素对于改善这一弱势群体的结果至关重要.
研究的目的:
- 调查与早产婴儿肠道疾病 (ID) 的发展相关的潜在产科风险因素.
- 探索胎儿生长限制 (FGR) 与ID发病率之间的关系.
- 检查长期多普勒异常对智商发育的影响.
主要方法:
- 对单个早产婴儿 (怀孕22 0/7至28 6/7周) 的回顾性分析,这些婴儿在2013年至2022年之间出生,并没有先天性异常.
- 产科因素的比较,包括母亲的背景,并发症,FGR,chorioamnionitis,Apgar得分和动脉血液气体,在ID和对照组的婴儿之间.
- 统计分析以确定已识别的风险因素的意义.
主要成果:
- 在119名早产儿中,22名 (18.5%) 患有智障,包括MRI (14),FIP (4) 和NEC (5).
- 胎儿生长限制 (FGR) 在ID组 (45.5%) 与非ID组 (23.7%,p=0.047) 相比显著更为普遍.
- 患有ID和FGR的婴儿从多普勒异常开始到分娩 (180小时) 的间隔比没有ID (24小时,p=0.049) 的婴儿要长得多.

Teratogenicity
4.0K
The ability of a drug to produce structural deformations and functional abnormalities in the developing embryo or the fetus is called teratogenicity, and the drug producing this effect is known as a teratogen. Teratogenic effects include stillbirth, miscarriage, intrauterine growth restriction, and neurocognitive delay. A teratogen may affect the embryo at different stages of development, which is important in determining the type and extent of the damage. During blastocyst formation, the early...

Anatomy of the Intestines
86.8K
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...

Inborn Errors of Metabolism
697
Phenylketonuria (PKU) is a protein metabolism disorder characterized by high blood levels of the amino acid phenylalanine. This results from a mutation in the gene responsible for phenylalanine hydroxylase, an enzyme that converts phenylalanine into tyrosine. When this enzyme is deficient, phenylalanine builds up in the blood, leading to symptoms such as vomiting, rashes, seizures, growth deficiency, and severe mental retardation. An early diagnosis and a diet restricting phenylalanine intake...

Glucose Transporters
27.2K
Glucose transporters facilitate the transport of glucose across the cell membrane. In addition to glucose, some glucose transporters can also aid the movement of other hexoses such as fructose, mannose, and galactose.
Facilitated diffusion-glucose transporters (GLUTs) are encoded by the solute-linked carrier (SLC) family 2, subfamily A gene family, or SLC2A. The 14 GLUT protein members are distributed into three classes:

Gastrointestinal Motility Disorders
1.1K
Gastrointestinal or GI motility disorders are characterized by irregular gastrointestinal tract movements, disrupting food transit from the mouth to the anus. They are caused by damage or dysfunction in gut muscles or nerves. These disorders can cause symptoms such as severe constipation, diarrhea, abdominal pain, and swallowing difficulties. Disorders can affect any segment of the GI tract and range widely in severity, from common conditions like GERD to life-threatening conditions like...

Pathophysiology of Diabetes
3.2K
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,...
