概括
患有左心室缩 (LVH) 的儿童移植受体在移植前血红蛋白水平较低,移植后血红蛋白水平较快增加. 左心室质量指数和射出分数的变化预测了血红蛋白的变化.
科学领域:
- 心脏病学 心脏病学
- 腎臟病學 (nephrology) 是一種醫學專業.
- 移植医学 移植医学
背景情况:
- 移植 (KTx) 后贫血很常见,并且与较差的移植存活率有关.
- 移植后早期血红蛋白 (Hb) 的时间变化及其与心脏功能的关联尚未得到充分了解.
研究的目的:
- 为了研究早期移植后期血红蛋白 (Hb) 水平及时变化与儿科脏移植接受者的左心室 (LV) 和左心房 (LA) 功能和应变之间的关系.
主要方法:
- 心声检查评估了71名儿科KTx接受者在KTx前和后6个月内的心脏结构,功能和应变.
- 接受者根据LV质量指数 (LVMI) 分为左心室缩 (LVH) 和非LVH组.
主要成果:
- LVH组在KTx前的Hb水平和贫血发病率较低,在KTx后正常化.
- 在LVH组中观察到Hb增加的速度更快.
- 没有Hb增加与LVMI负相关,与LV射出分数 (LVEF) 和LA菌株正相关.
结论:
- 患有LVH的儿童在KTx前后表现出明显的Hb模式.
- LVMI,LVEF变化和LA排空量指数 (LAEVI) 预测KTx后没有Hb增加.

Bone Marrow Sampling and Transplants
265
Bone marrow transplant is a potential cure for several diseases, including cancer and specific genetic disorders. Notably, this procedure is applicable for patients suffering from aplastic anemia, certain types of leukemia, severe combined immunodeficiency disease (SCID), Hodgkin's disease, non-Hodgkin's lymphoma, multiple myeloma, thalassemia, sickle-cell disease, and certain cancers.
The transplant begins with high doses of chemotherapy and radiation treatment, which aim to destroy...

Factors Affecting Erythropoiesis
3.0K
The cardiovascular system regulates the number of erythrocytes in the bloodstream to ensure optimal oxygen transport. It also prevents over-proliferation of these cells, which helps to maintain blood viscosity and flow rate.
Several factors influence the erythrocyte production rate, with tissue oxygen level being among the most critical. Intense exercise or high altitudes can cause tissue hypoxia, which triggers the kidneys to release more erythropoietin (EPO) into the bloodstream.
EPO then...
