概括

在接受红细胞输血的老年骨髓质疏松综合征 (MDS) 患者中,铁化疗 (ICT) 显著降低了死亡率,急性骨髓性白血病 (AML) 风险和心脏问题. 这些真实世界的数据支持了ICT对这一群体的好处.

科学领域:

血液学血液学血液学
在瘤学瘤学.
老年医学老年医学

背景情况:

来自红细胞 (RBC) 输血的铁过载是肌肉分裂综合征 (MDS) 的一个主要问题,有助于发病率和死亡率.
在老年MDS患者中,铁化疗 (ICT) 疗效的证据有限.

研究的目的:

通过使用现实世界的数据,评估ICT在老年MDS患者的利用和结果.
评估ICT与生存,急性髓性白血病 (AML) 的发展以及与铁有关的并发症的关联.

主要方法:

对美国SEER-Medicare数据库 (2007-2017年) 对MDS患者年龄≥66岁,存活时间≥2年进行分析.
通过记录的铁过载和/或显著的红细胞输血史来定义ICT的资格.
使用多变量Cox危险模型和倾向性得分匹配评估结果.

主要成果:

15.3%的符合条件的老年MDS患者接受了ICT,其中deferasirox和deferoxamine是最常见的药物.
根据特定的组织学特征和同时使用的疗法 (例如,低甲基化剂,莱纳利多米德) 预测了ICT的使用.
在依赖输血的患者中,ICT与47%-48%的死亡风险降低,43%-49%的AML风险降低和23%-32%的心脏不良结果风险降低有关.

结论:

铁化疗法 (ICT) 与老年MDS患者的生存率改善和AML和心脏并发症风险降低有关.
调查结果表明,尽管先前的证据有限,ICT对于管理这个脆弱人群的铁过载是有益的.
进一步的研究可能会探索老年MDS患者的最佳ICT策略.

Complexation Equilibria: The Chelate Effect

Complexation Equilibria: The Chelate Effect

In complexation reactions, metal atoms or cations interact with ligands to form donor-acceptor adducts called metal complexes. Ligands that bind through one donor site are monodentate, ligands with two donor sites are bidentate, and those with more than two donor sites are polydentate ligands. For example, ethylene diamine is a bidentate ligand that binds through two nitrogen donor atoms, forming a five-membered ring. EDTA is a polydentate ligand that binds through four oxygen and two nitrogen...

Peritoneal Dialysis III: Nursing Management

Peritoneal dialysis, or PD, utilizes the peritoneal membrane as a filter to eliminate excess fluid and waste products. Effective nursing management is essential for ensuring patient safety, preventing complications, and promoting optimal function of the peritoneal dialysis process.Assessment and MonitoringNurses must thoroughly assess the patient before, during, and after each dialysis session. Regular monitoring includes vital signs, daily weight, fluid intake and output, and laboratory values...
