概括
胎儿腹部皮下组织厚度 (FASTT) 在妊娠糖尿病复杂的怀孕中显示出与出生体重的弱相关性. 虽然FASTT可以区分胎儿生长类别,但腹周是妊娠年龄新生儿大体的优越预测指标.
科学领域:
- 产科和妇科 产科和妇科
- 胎儿医学 胎儿医学
- 新生儿研究新生儿研究
背景情况:
- 妊娠期糖尿病 (GDM) 与胎儿脂肪沉积增加有关,特别是在妊娠年龄大于 (LGA) 的胎儿中.
- 胎儿腹部皮下组织厚度 (FASTT) 是一种超声波测量,反映了腹部脂肪沉积.
- 准确预测LGA新生儿对于管理妊娠并发症和优化新生儿结果至关重要.
研究的目的:
- 评估FASTT与患有GDM的母亲胎儿出生体重之间的相关性.
- 为了比较FASTT和腹周长 (AC) 的预测性能,用于识别GDM怀孕中的LGA新生儿.
主要方法:
- 一项前性研究涉及150名终身GDM妇女.
- 每周进行FASTT的超声波测量.
- 相关性分析和接收器运行特征 (ROC) 曲线,以评估FASTT和AC用于LGA预测.
主要成果:
- 在FASTT和出生体重之间观察到微弱的正相关性 (r=0.375).
- 对于预测LGA胎儿,FASTT的灵敏度为68.8%,特异性为68.7%,截止值为≥8.05毫米.
- 腹周 (AUC=0.755) 与FASTT (AUC=0.692) 相比,LGA新生儿的预测性能更好.
结论:
- 由于相关性较弱,FASTT作为预测GDM怀孕中出生体重的独立查工具的实用性有限.
- 快速可以区分小的妊娠年龄 (SGA),适合妊娠年龄 (AGA),和LGA胎儿.
- 腹周是比FASTT更有效的超声波参数,用于预测LGA新生儿在GDM的背景下.

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...

Pathophysiology of Diabetes
920
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: Symptoms, Diagnosis, and Complications
523
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...
