概括

较低体积的心脏移植中心使用状态2例外比较高体积中心更频繁. 随着移植中心的数量增加,例外使用的数量显著下降.

科学领域:

心血管外科心血管外科
移植医学移植医学
医疗保健服务研究医疗服务研究

背景情况:

关于心脏移植中心数量与利用状态2例外的关系的数据有限.
了解这种关系对于优化器官分配和移植结果至关重要.

研究的目的:

检查每年心脏移植中心数量与申请状态2例外率之间的关联.
确定移植中心的体积是否会影响特定器官分配例外的使用.

主要方法:

使用状态2例外情况 (2018年底-2023年初) 对心脏移植 (OHT) 器官采购和移植网络 (OPTN) 数据库的回顾性分析.
根据每年OHT量分类中心:非常低 (<5),低 (5-24),中等 (25-50) 和高 (>50).
发病率比率 (IRR) 被计算出来,以比较各个体积类别的异常申请率.

主要成果:

总共分析了6348个OHT;68个非常低,1001个低,1834个中等和3445个高体积的中心.
非常低和低数量的中心申请了50-60%的状态2例外,而中高数量的中心则申请了30-35%.
与非常低的体积中心相比,中型和高体积中心申请的状态2例外数量明显减少 (IRR分别为0.52和0.42;p < 0.001).

结论:

较低体积的心脏移植中心显示了显著更高的状态2例外申请率.
心脏移植中心的数量和使用状态2例外之间存在明显的反向关系.
调查结果表明,可能需要审查不同中心体积的例外标准或分配政策.

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...

Cardiac Output II: Effect of Stroke Volume on Cardiac Output

725

Cardiac output (CO), the amount of blood the heart pumps per minute, is a parameter in cardiovascular physiology determined by stroke volume and heart rate. Stroke volume, the amount of blood pushed from one of the ventricles per heartbeat, is influenced by preload, afterload, and contractility.
Preload
Preload refers to the initial elongation of the cardiac myocytes before contraction and is related to the volume of blood filling the heart at the end of diastole, or end-diastolic volume. The...

Cardiomyopathy V: Interprofessional Care

Managing cardiomyopathy involves addressing underlying or precipitating causes, treating heart failure with medications, and implementing dietary changes and a balanced exercise and rest regimen.Lifestyle ModificationsCardiomyopathy patients should adopt a low-sodium diet to reduce fluid retention and manage heart failure. A personalized exercise and rest plan helps maintain physical fitness without overstraining the heart. Avoiding alcohol and tobacco is essential to prevent further damage to...

Cardiac Output and Stroke Volume

2.9K

Cardiac output (CO) is an integral aspect of human physiology, reflecting the heart's efficiency and responsiveness to the body's needs. It represents the volume of blood that the left or right ventricle ejects into the aorta or pulmonary trunk each minute. The CO is calculated by multiplying the heart rate (HR)—the number of heartbeats per minute—by the stroke volume (SV)—the amount of blood pumped out with each heartbeat.
In an average resting adult male, the typical cardiac...
