概括
怀孕期间母亲的高血红蛋白水平与不良结果的风险增加有关. 目前的指导方针应考虑低血红蛋白值和高血红蛋白值,以改善母亲和新生儿的健康.
科学领域:
- 产科和妇科 产科和妇科
- 孕产妇和胎儿医学 孕产妇和胎儿医学
- 血液学 血液学 血液学
背景情况:
- 怀孕期间的贫血是全球重要的健康问题,导致母亲和新生儿的发病率和死亡率.
- 研究母亲血红蛋白水平与不良妊娠结果之间的关系对于改善护理至关重要.
研究的目的:
- 检查整个怀孕期间母亲血红蛋白度与母亲和新生儿不良结果的风险之间的关联.
- 评估当前世界卫生组织 (WHO) 血红蛋白切断值在预测这些风险方面的充分性.
主要方法:
- 展望性,观察性,跨国研究 (INTERBIO-21st) 涉及巴西,肯尼亚,巴基斯坦,南非和英国的孕妇.
- 收集了2069名怀孕14周至40周之间的女性的常规产前护理数据,包括血红蛋白值.
- 评估了母亲的结果 (孕期糖尿病,怀孕引起的高血压,膜的早产早破) 和新生儿的结果 (对于妊娠年龄来说很小,早产,急性呼吸困扰综合征).
主要成果:
- 与血红蛋白切断值为110g/L相比,170g/L及以上的度显示,怀孕引起的高血压风险增加了两倍以上 (RR 2.29).
- 在血红蛋白度为70 g/L (RR 2.04) 和165 g/L (RR 2.06) 的情况下,早产风险增加.
- 在血红蛋白度为165g/L (RR 2.84) 的情况下,急性呼吸困扰综合征的风险显著增加 (RR 2.84).
结论:
- 世卫组织目前的血红蛋白切断似乎与降低对母亲和新生儿不良结果的风险有关.
- 血红蛋白度和不良结果之间存在U形关系,这表明需要为高血红蛋白水平建立值,而不仅仅是低.
- 怀孕护理指南应包括低血红蛋白度和高血红蛋白度值,以有效减轻风险.

Fetal Circulation
1.1K
Fetal circulation is a unique system that facilitates the exchange of gases, nutrients, and waste products between the developing fetus and the mother. This intricate process takes place through a special organ called the placenta.
Two umbilical arteries transport blood from the fetus to the placenta. At the placenta, the blood absorbs oxygen and nutrients while simultaneously eliminating waste products. This oxygen-enriched and nutrient-rich blood then returns to the fetus through one...

Transcytosis of IgG
2.8K
Transcytosis is the process in which molecules are internalized by endocytosis, transported across the cell, and released through exocytosis from the opposite end of the cell. Molecules such as insulin, immunoglobulins, and certain nutrients are transferred through the recycling endosomes by recycling and transcytosis.
IgG molecules from a mother undergo transcytosis starting around 13 weeks of gestation. The amount of IgG transferred and entering the fetal blood circulation increases with...

Pathophysiology of Diabetes
1.0K
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,...

Hemoglobin
3.8K
Hemoglobin is a globular protein made up of four subunits. Two of these subunits are alpha chains, and the other two are beta chains. Each subunit contains a molecule of heme, which has an iron atom and can bind to oxygen. When an oxygen molecule binds to one heme group, it changes the shape of hemoglobin, making it easier for the other heme groups to bind oxygen as well.
When all four heme groups are bound to oxygen, the resulting molecule is called oxyhemoglobin. As a result, arterial blood...
