概括

体积的变化可以预测移植功能下降,提供了一个新的非侵入性生物标志物. 手术前脏尺寸较小和脏体积减少表明移植功能较差,突出显示了脏在免疫监测中的作用.

科学领域:

腎臟病學 (nephrology) 是一種醫學專業.
放射学放射学是一门学科.
免疫学免疫学免疫学

背景情况:

接受脏移植的接受者需要可靠的生物标志物来预测移植功能.
像电阻指数 (RI) 这样的传统成像参数在预测长期结果方面存在局限性.
脏在移植后免疫动力学中的作用未被充分认识到.

研究的目的:

评估体积及其变化作为移植功能的非侵入性生物标志物.
为了比较体积测量的预后性能与动脉电阻指数 (RI).
为了确定移植后第一年内移植功能下降的预测因素.

主要方法:

对76名移植接受者的回顾性研究.
使用手术前和手术后6个月的CT扫描进行体积测量脏和移植.
1个月和6个月的抗性指数 (RI) 多普勒超声扫描.
淋巴膜过率 (GFR) 的下降定义为≥10mL/min/1.73m2的下降,1个月和12个月.

主要成果:

移植功能下降的患者在手术前和6个月后的RI值更高,RI变化更大.
手术前脏体积较小与移植功能下降有关.
6个月时脏体积的减少与12个月时移植功能较差相关 (p=0.004).
移植体积及其变化与移植功能没有显著的关联.

结论:

体积变化作为一种新的,可访问的成像生物标志物,用于预测移植功能下降.
体积反映了移植患者的全身免疫激活和免疫储备.
常规CT体积测试可以重新定义在移植后免疫监测中的作用.

Drug Dosing in Renal Diseases: Estimation of Glomerular Filtration Rate Based on Serum Creatinine Concentration

Glomerular filtration rate (GFR) can be estimated from serum creatinine using the modification of diet in renal disease (MDRD) formula or the chronic kidney disease–epidemiology collaboration (CKD–EPI) equation. Both methods are widely used in clinical practice to assess kidney function and guide treatment decisions.The MDRD equation does not require weight or height measurements and is normalized to the body surface area of 1.73 m², considered the average adult surface area.

Acute Kidney Injury IV: Diagnostic Studies and Prevention

Accurate diagnosis and effective prevention are critical in managing Acute Kidney Injury (AKI), which is linked to high mortality rates ranging from 10% to 80%. Timely recognition of at-risk patients and careful monitoring can significantly reduce the likelihood of kidney damage.Diagnostic Assessments:The diagnostic process starts with a comprehensive medical history to identify prerenal, intrarenal, and postrenal causes.Prerenal causes, such as dehydration, hypotension, or blood loss, should...

Kidney Transplant I: Introduction

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...
