概括
怀孕期间低血糖挑战测试 (GCT) 与较高的新生儿死亡率有关,特别是对于妊娠年龄 (SGA) 的婴儿来说. 这表明,对具有低GCT结果的母亲进行更密切的产前监测可能有潜在的好处.
科学领域:
- 产科和妇科 产科和妇科
- 新生儿医学 新生儿医学
- 内分泌学 在内分泌学.
背景情况:
- 50克,1小时葡萄糖挑战测试 (GCT) 是妊娠糖尿病 (GDM) 的标准查工具.
- 与高值相比,低于平均水平的GCT值对潜在的不良结果没有得到充分研究.
- 了解与低GCT值相关的结果对于全面的产前护理至关重要.
研究的目的:
- 为了研究低50克,1小时葡萄糖挑战测试 (GCT) 值与母亲和新生儿不良结果之间的关联.
- 为了比较低GCT值的怀孕的结果与正常的血糖查和诊断的GDM.
主要方法:
- 从2013年到2021年,对36342名孕妇进行了回顾性队列研究.
- 定义低GCT为≤10百分位数 (<82 mg/dL),并将结果与没有GDM的GCT≥82 mg/dL患者进行比较.
- 主要结局是综合新生儿发病率变量,包括死胎,新生儿死亡,因低血糖症,高白血症,呼吸困难和/或SGA而入院NICU.
主要成果:
- 10.4%的患者具有较低的GCT值 (<82 mg/dL).
- 与正常血糖查相比,低GCT与妊娠高血压障碍,剖腹产和产后出血率显著降低.
- 低GCT值的母亲的新生儿患复合发病风险显著增加 (aOR 1.18;95% CI 1.09-1.29),这是由于SGA的发病率更高所致.
结论:
- 怀孕24周后母亲的低GCT值与新生儿发病率的增加显著相关,主要是由于怀孕年龄较小 (SGA) 的比率较高.
- 潜在的孕产妇低血糖或血糖失调可能会影响胎儿的发育.
- 低GCT值的患者可能受益于加强产前监测.

Pathophysiology of Diabetes
989
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
2.5K
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...

Glucose Transporters
22.9K
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:

Hypoglycemia and Glucagon
297
Without prolonged fasting, healthy individuals maintain blood glucose levels above 3.5 mM due to a well-adapted neuroendocrine counterregulatory system that effectively prevents acute hypoglycemia, a potentially life-threatening condition. The primary clinical scenarios for hypoglycemia encompass diabetes treatment, inappropriate production of endogenous insulin or insulin-like substances by tumors, and the use of glucose-lowering agents in non-diabetic individuals. Notably, hypoglycemia in the...

Diabetes: Symptoms, Diagnosis, and Complications
590
For most patients, experiencing several weeks of polyuria, polydipsia, fatigue, and significant weight loss may indicate the presence of diabetes. Furthermore, adults displaying the phenotypic appearance of type 2 diabetes (particularly those who are obese and not initially insulin-requiring), may have islet cell autoantibodies, suggesting autoimmune-mediated β cell destruction and a diagnosis of latent autoimmune diabetes of adults (LADA). The categorization of glucose homeostasis is...

Glucose Homeostasis: Regulation of Blood Glucose
1.8K
Carbohydrates consumed through foods are converted into glucose, a crucial energy source for the body. In the prandial state, high blood glucose levels stimulate the secretion of insulin from the pancreas. Insulin inhibits hepatic glucose production and stimulates glucose uptake and metabolism by muscle and adipose tissue. The excess glucose is converted into glycogen and stored in the liver and muscles.
During fasting, when blood glucose levels are low, the pancreas secretes glucagon. it...
