概括
在移植中解决种族差异至关重要. 一个新的联合学习框架,dGEM-disparity,发现将非西班牙裔黑人 (NHB) 患者的入院与非西班牙裔白人 (NHW) 的入院模式对齐,可以每年减少每10,000名NHB患者中的38例移植失败.
科学领域:
- 健康 公平 研究 健康 公平 研究
- 移植医学 移植医学 移植医学
- 医疗保健中的数据隐私
背景情况:
- 在美国,非西班牙裔黑人 (NHB) 和非西班牙裔白人 (NHW) 患者之间的移植机会和结果存在显著的种族差异.
- 护理地点是导致这些差异的一个主要因素.
- 患者隐私法规阻碍了使用多站点数据来研究这些影响.
研究的目的:
- 开发和验证一个联合学习框架 (dGEM-差异) 来分析移植中的种族差异.
- 量化护理地点对NHB和NHW患者之间的差异的影响.
- 通过调整移植中心患者分布来评估移植失败的潜在减少.
主要方法:
- 开发了dGEM-disparity,这是一个使用来自多个中心的汇总数据的联合学习框架.
- 采用了两模块的方法:估计常见和医院特定的影响,然后应用反事实建模.
- 通过模拟NHB患者入院率来评估移植失败率,以反映NHW患者分布.
主要成果:
- 利用了10年来73个移植中心的39,043名成年患者的数据.
- 发现将NHB患者入院数与NHW患者分布对齐,可以在一年内将每10,000名NHB患者中的38人死亡或移植失败减少.

Determination of Renal Drug Clearance: Graphical and Midpoint Methods
501
Renal clearance, a crucial parameter in pharmacokinetics, can be determined using two different methods: the graphical method and the midpoint method. These methods provide insights into the rate of drug excretion by the kidneys and aid in assessing renal function.
The graphical method involves plotting the rate of drug excretion in urine against the plasma drug concentration. By analyzing the graph, the clearance can be calculated and obtained. Drugs rapidly excreted by the kidneys exhibit a...

Drug Dosing in Renal Diseases: Measurement of Glomerular Filtration Rate
146
The glomerular filtration rate (GFR) is a critical indicator of kidney health, reflecting how well the kidneys filter blood. Changes in GFR can signal potential kidney impairment, necessitating accurate measurement methods to monitor kidney function effectively.Various molecules can serve as markers for GFR measurement, with the ideal marker meeting several specific criteria. It must freely filter at the glomerulus, avoid reabsorption or secretion by the renal tubules, remain unmetabolized, not...

Drug Dosing in Renal Diseases: Estimation of Glomerular Filtration Rate Based on Serum Creatinine Concentration
342
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.
