Abstract

Objective: Patients with acute ischemic stroke (AIS) have limited evidence regarding the relationship between blood urea nitrogen and albumin. Aiming to investigate the relationship between the blood urea nitrogen to albumin ratio (BUN/ALB ratio) and poor outcomes in AIS patients at 3 months was the purpose of this study.

Methods: AIS participants at a Korean hospital from January 2010 to December 2016 were included in a secondary analysis of a prospective cohort study. Logistic regression and restricted cubic splines were used to examine the relationship between BUN/ALB ratio and poor outcomes after 3 months.

Results: There is a skewed distribution of BUN/ALB ratios, ranging from 0.114 to 1.250. Model II of the binary logistic regression showed that the BUN/ALB ratio was not statistically significant in predicting poor outcomes for AIS patients after 3 months. However, there was a notable nonlinear relationship between them, with the inflection point of the BUN/ALB ratio identified as 0.326. The BUN/ALB ratio on the left side of the inflection point was associated with a 42% reduction in 3-month poor outcomes (odds ratio = 0.58, 95% confidence interval: 0.40 to 0.83). Conversely, the relationship was not statistically significant on the right side of the inflection point.

Conclusions: The BUN/ALB ratio and poor outcomes in AIS patients show a nonlinear correlation. For AIS patients, a BUN/ALB ratio of approximately 0.326 is associated with the lowest risk of adverse outcomes at 3 months. Specifically, for nonsmoking AIS patients, a BUN/ALB ratio of approximately 0.295 is associated with the lowest risk of adverse outcomes at 3 months.

急性缺血性脑卒中患者血尿素氮与白蛋白比率与 3 个月预后之间的非线性关系:基于前瞻性队列研究的第二次分析。
目的:关于急性缺血性脑卒中(AIS)患者血尿素氮和白蛋白(BUN/ALB)之间关系的证据有限。本研究旨在调查 AIS 患者 3 个月后血尿素氮/白蛋白比率与不良预后之间的关系:方法:一项前瞻性队列研究的二次分析纳入了韩国一家医院 2010 年 1 月至 2016 年 12 月期间的 AIS 患者。结果:BUN/ALB比值与3个月后的不良预后之间存在偏态分布:结果:BUN/ALB 比率呈倾斜分布,从 0.114 到 1.250 不等。二元逻辑回归模型 II 显示,BUN/ALB 比率在预测 AIS 患者 3 个月后的不良预后方面没有统计学意义。但是,两者之间存在明显的非线性关系,BUN/ALB 比值的拐点确定为 0.326。在拐点左侧的 BUN/ALB 比值与 3 个月后不良预后减少 42% 相关(OR=0.58,95% CI:0.40 至 0.83)。相反,在拐点的右侧,这种关系没有统计学意义:结论:BUN/ALB 比值与 AIS 患者的不良预后呈非线性相关。对于 AIS 患者,BUN/ALB 比率约为 0.326 与 3 个月不良预后的最低风险相关。具体来说,对于不吸烟的 AIS 患者,BUN/ALB 比率约为 0.295 与 3 个月后不良预后的最低风险相关。

期刊介绍: World Neurosurgery has an open access mirror journal World Neurosurgery: X, sharing the same aims and scope, editorial team, submission system and rigorous peer review. The journal''s mission is to: -To provide a first-class international forum and a 2-way conduit for dialogue that is relevant to neurosurgeons and providers who care for neurosurgery patients. The categories of the exchanged information include clinical and basic science, as well as global information that provide social, political, educational, economic, cultural or societal insights and knowledge that are of significance and relevance to worldwide neurosurgery patient care. -To act as a primary intellectual catalyst for the stimulation of creativity, the creation of new knowledge, and the enhancement of quality neurosurgical care worldwide. -To provide a forum for communication that enriches the lives of all neurosurgeons and their colleagues; and, in so doing, enriches the lives of their patients. Topics to be addressed in World Neurosurgery include: EDUCATION, ECONOMICS, RESEARCH, POLITICS, HISTORY, CULTURE, CLINICAL SCIENCE, LABORATORY SCIENCE, TECHNOLOGY, OPERATIVE TECHNIQUES, CLINICAL IMAGES, VIDEOS
