概括
在体力活动之前摄入蛋白质可能会降低1型糖尿病青少年的低血糖风险. 运动后4小时内至少10g或0.125g/kg蛋白质的剂量与运动期间低血糖的时间较短有关.
科学领域:
- 内分泌学 在内分泌学.
- 运动医学 运动医学
- 儿科 儿科 儿科
背景情况:
- 患有1型糖尿病 (T1D) 的青少年在体育活动期间面临管理血糖的挑战.
- 了解运动前营养的影响,特别是蛋白质摄入量,对于优化这一群体的血糖控制至关重要.
研究的目的:
- 研究1型糖尿病青少年中中度至剧烈体力活动 (MVPA) 之前的蛋白质摄入量与血糖控制之间的关联.
- 确定最佳的蛋白质摄入水平,以降低低血糖期间和之后的低血糖风险.
主要方法:

- 利用持续的葡萄糖监测和24小时的饮食回忆来评估血糖参数和蛋白质摄入量.
- 采用混合效应回归模型来分析运动前蛋白质摄入量与低血糖时间 (TBR),范围内的时间和范围以上时间之间的关系.
主要成果:
- 在MVPA前4小时内摄入≥10g或≥0.125g/kg的蛋白质与体力活动期间低于范围 (低血糖) 的时间显著减少有关.
- 在摄入量为10-19.9g (-4.41%) 和>20g (-4.83%),以及0.125-0.249g/kg (-5.38%) 和≥0.25g/kg (-4.32%) 的摄入量时,观察到TBR的具体降低.

Insulin: Dosing Regimen and Adverse Effects
175
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...

Hypoglycemia and Glucagon
263
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 Mellitus: Overview and Type I Subtype
2.6K
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...

Diabetes Mellitus: Type 2 and Gestational
2.4K
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...

Hormones Regulating Blood Glucose
3.4K
Insulin is released by beta cells of the pancreas when blood glucose levels are high. It facilitates glucose absorption and utilization in insulin-dependent cells with insulin receptors on their plasma membranes. Insulin promotes glucose uptake by increasing the number of glucose transport proteins in the cell membrane, allowing glucose to enter the cell. As a result, glucose utilization and ATP production are enhanced.
In addition to accelerating glucose uptake and utilization, insulin has...

Oral Hypoglycemic Agents: Glinides
156
Repaglinide (Prandin) and Nateglinide (Starlix), known as glinides, are oral insulin secretagogues that stimulate insulin release from pancreatic β cells by closing the ATP-sensitive potassium channels (KATP channel). Repaglinide controls insulin release from pancreatic β cells by managing potassium efflux. It shares two binding sites with sulfonylureas and also has a unique site, indicating overlapping mechanisms of action. With a rapid onset and a 4-7 hour duration, it effectively...
