概括
对于患有1型糖尿病 (T1D) 的孕妇来说,超过50%的超算时间范围 (eTIR) 显著降低了早产,新生儿呼吸困难和妊娠年龄大 (LGA) 婴儿的风险. 这强调了怀孕期间血糖控制的重要性.
科学领域:
- 内分泌学
- 产周医学
- 糖尿病学
背景情况:
- 孕期1型糖尿病 (T1D) 需要严格的血糖控制,以减轻周产期不良结果.
- 自我监测血糖 (SMBG) 数据可用于估计时间范围 (TIR),这是一个关键的血糖指标.
- 额外推算的TIR (eTIR) 提供了对T1D孕妇SMBG血糖控制的有价值的评估.
研究的目的:
- 研究由SMBG推断的时间范围 (eTIR) 与T1D复杂的怀孕中不良产周结局之间的关联.
- 确定特定的eTIR值是否与降低新生儿和母亲重大并发症的风险相关.
主要方法:
- 一次性妊娠的回顾性队列研究 (2010-2019).
- 使用SMBG的血糖数据来计算eTIR,分类为<50%,50% - 70%和>70%.
- 多变量逻辑回归分析了eTIR类别与早产,新生儿呼吸困难和LGA婴儿等结果之间的关系.
主要成果:
- 与 eTIR < 50% 相比,较高的 eTIR (50% - 70% 和> 70%) 与早产,新生儿呼吸困难和LGA婴儿的几率显著降低有关.
- 具体来说,ETIR>50%显示出对这些不良结果的保护作用.
- 这项研究分析了140例怀孕的数据,其中26.4%的怀孕率超过了70%.
结论:
- 达到50%以上的eTIR与T1D孕妇出现关键不良周产期结局的风险显著降低.
- 这些发现强调了优化血糖控制的临床重要性,即使使用SMBG衍生的指标,以改善妊娠结果.
- 这项研究强调了eTIR作为治疗妊娠期T1D的实际目标的潜力.

Diabetes Mellitus: Type 2 and Gestational
2.9K
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
1.2K
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,...

Diabetes Mellitus: Overview and Type I Subtype

Diabetes mellitus is a chronic metabolic disorder characterized by high blood glucose levels due to inadequate insulin production, insulin resistance, or both. The condition affects millions worldwide and can significantly impact their health and quality of life.
Type 1 diabetes is an autoimmune disease in which the immune system mistakenly attacks and destroys the insulin-producing beta cells in the pancreas. As a result, the body is unable to produce sufficient insulin, and individuals with...

Insulin: Dosing Regimen and Adverse Effects
252
Insulin-replacement therapy usually includes both long-acting insulin (basal) and short-acting insulin (to cater to postprandial needs). In a diverse group of type 1 diabetes patients, the average daily insulin dose is typically 0.5-0.7 units/kg body weight. However, obese patients and pubertal adolescents may need more due to insulin resistance.
The basal dose constitutes about 40%-50% of the total daily dose, with the rest as premeal insulin. The mealtime insulin dose should mirror...

Diabetes: Symptoms, Diagnosis, and Complications
684
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...

Regression Toward the Mean
6.5K
Regression toward the mean (“RTM”) is a phenomenon in which extremely high or low values—for example, and individual’s blood pressure at a particular moment—appear closer to a group’s average upon remeasuring. Although this statistical peculiarity is the result of random error and chance, it has been problematic across various medical, scientific, financial and psychological applications. In particular, RTM, if not taken into account, can interfere when...
