- 糖尿病 テクノロジー
背景:
- 高血糖症は,妊娠中の1型糖尿病の女性に重大なリスクをもたらす.
- 閉路インスリンシステムは,妊娠外でのグルコース管理に有効であることが示されています.
- 妊娠中の閉路システムの使用と有効性に関するデータは限られている.
研究 の 目的:
- 1型糖尿病の妊婦における閉環インスリンシステムの有効性を評価する.
- 1型糖尿病の妊婦の血糖コントロールを,閉路システムと標準治療を比較する.
主な方法:
- カナダとオーストラリアの14のセンターで実施された ランダム化試験です
- 1型糖尿病の妊婦は,閉環療法または継続的なグルコースモニタリングによる標準的なインスリン投与にランダムに割り当てられました.
- 測定された主な結果は,妊娠16週から34週間の妊娠特有のグルコース範囲 (63-140 mg/ dL) の内での時間の割合でした.
主要な成果:
- 標準治療群の50. 3%と比較して,閉路群は平均65. 4%の時間を目標グルコース範囲に費やした.
- これは12.5パーセントポイントの大幅な調整差 (P < .001) を表しています.
- 副作用には,重度の低血糖症のエピソードと,両方のグループで糖尿病性ケトアシドーシスのエピソードが含まれていた.

Diabetes Mellitus: Type 2 and Gestational
4.2K
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...

Insulin: Dosing Regimen and Adverse Effects
644
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 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 Formulations: Types and Delivery
597
Insulin preparations are categorized by their duration of action into short-acting and long-acting types. Two strategies are used to modify insulin's absorption and pharmacokinetic profile: slowing the absorption post-subcutaneous injection, or altering human insulin's amino acid sequence or protein structure. These changes retain the insulin's ability to bind to the insulin receptor, but alter its behavior in solution or after injection.

Pathophysiology of Diabetes
3.1K
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: Management and Pharmacotherapy
835
The therapy for diabetes aims to alleviate hyperglycemia-related symptoms, prevent acute metabolic decompensation, and reduce chronic end-organ complications. Glycemic control is evaluated through short-term (self-monitoring, continuous glucose monitoring) and long-term (A1c, fructosamine) metrics, enabling near real-time tracking of blood glucose levels and reflecting glycemic control over specific time frames.
