まとめ
新生児の低血糖症のリスクは,母乳で育った乳児と,母乳で育った乳児の血糖値が低いにもかかわらず,同じであった. これらの発見はリスクの高い新生児の母乳育児を優先することを支持しています
科学分野:
- 新生児の生理学
- 小児の栄養
- 内分泌学
背景:
- 新生児の血糖調節は出生後に急速に変化し,リスクのある乳児は低血糖症に直面します.
- 早期の栄養摂取は極めて重要ですが,栄養の種類がグルコースの恒常状態に与える影響は不明です.
研究 の 目的:
- 乳食のみを摂取した新生児と乳食配給の新生児の血糖の経路と低血糖の発生を比較する.
主な方法:
- リスクのある新生児192人の前向きな観察コホート研究.
- 生後2,6,12,18,24時間で血糖値が測定されました.
- 低血糖は<3.0 mmol/Lと定義され,リスク評価にはロジスティック回帰を用いる.
主要な成果:
- 配方栄養を摂取した新生児の血糖値は6,12,24時間 (p<0. 05) で高かった.
- 蓄積されたグルコース暴露 (AUC) は,配方栄養を摂取した乳児ではより高かった (85. 1 vs 80. 5 mmol/ L- hour).
- 低血糖の総発生率 (<3. 0 mmol/ L) は,グループごとに似ていた (14. 7% 対 11. 1%, p=0. 615).
結論:
- 母乳で育った新生児の血糖値は低かったが,栄養食で育った新生児の血糖低下リスクは同じだった.
- リスクの高い新生児に 母乳の授乳を優先させるべきだと 結論付けています
- 栄養の長期的代謝結果に関するさらなる研究が必要である.

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,...

Hypoglycemia and Glucagon
334
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: 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...

Glucose Transporters
24.1K
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:

Glucose Homeostasis: Regulation of Blood Glucose
2.5K
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...

Oral Hypoglycemic Agents: Biguanides and Glitazones
288
Biguanides, particularly metformin (Glucophage), are insulin sensitizers that enhance glucose uptake, thereby reducing insulin resistance. Unlike sulfonylureas, metformin doesn't prompt insulin secretion, which helps to curb hypoglycemia risk. Metformin is beneficial in treating conditions like polycystic ovary syndrome due to its insulin-resistance reduction capability. The drug's primary action involves curtailing hepatic gluconeogenesis, a significant contributor to high blood...
