概括
与脑死亡 (DBD) 捐赠者相比,血液循环死亡 (DCD) 捐赠者的理想捐赠心脏使用量不足. 外体生命支持和冠状动脉血管学等干预预测利用率, 建议改善心脏移植产量的策略.
科学领域:
- 心血管外科
- 移植医学
- 器官捐献研究
背景情况:
- 循环死亡 (DCD) 之后的捐赠心脏移植比脑死亡 (DBD) 之后的捐赠更少使用.
- 在理想的DCD捐赠者中确定不足利用的因素对于改善器官产量至关重要.
研究的目的:
- 确定与理想的DCD捐赠者的心脏使用不足相关的因素.
- 在理想的DCD和DBD捐赠者之间比较心脏利用率.
主要方法:
- 来自联合器官共享网络 (UNOS) 数据库的患者级数据分析 (2020年1月至2023年12月).
- 理想的DCD和DBD捐赠者之间的心脏移植率的比较.
- 多变量逻辑回归以评估理想的DCD捐赠者的心脏利用率预测因素.
主要成果:
- 心脏全移植的利用率在DCD捐赠者 (6. 9%) 与DBD捐赠者 (35. 4%) 中显著较低.
- 在理想捐赠者中,使用了41%的DCD心脏,而使用了85%的DBD心脏.
- 在理想的DCD捐赠者中,体外生命支持 (OR 7. 48) 和冠状动脉图 (OR 2.77) 独立预测了心脏利用率.
结论:
- 很大一部分理想的DCD供体心脏仍未得到利用.
- 解决干预和区域差异等因素可能会提高DCD捐赠者的器官产量.

Bone Marrow Sampling and Transplants
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 the...

Kidney Transplant I: Introduction
A kidney transplant is a surgical approach that involves replacing a non-functioning kidney with a healthy one from a donor. This procedure is often a treatment option for end-stage renal disease (ESRD) patients. The method requires careful recipient selection, including evaluating various medical and psychosocial factors. These criteria vary between transplant centers but generally include assessments of the patient's overall health, adherence to medical recommendations, and lifestyle...
