概括

自然语言处理 (NLP) 从电子健康记录 (EHR) 中有效地提取了脊椎关节炎 (SpA) 患者数据. 这项技术可靠地描述了SpA配置文件,有助于理解和管理这种情况.

科学领域:

类风湿病学类风湿病学
医疗信息学医疗信息学
自然语言处理自然语言处理.

背景情况:

脊椎关节炎 (SpA) 是一组影响脊椎和关节的炎症性疾病.
鉴定脊髓炎患者的临床状况对于有效管理至关重要.
电子健康记录 (EHR) 包含大量患者数据,但从非结构化文本中提取信息是具有挑战性的.

研究的目的:

利用一种新的自然语言处理 (NLP) 技术从电子健康记录中提取临床信息.
在一家大型医院诊断出SPA的患者的临床特征.
评估NLP技术在检测SPA临床实体中的性能.

主要方法:

从SPA患者 (2020-2022) 获得的EHR数据的观察性,回顾性分析.
使用 Savana Manager 提取数据,这是一个基于 NLP 的系统,用于非结构化的 EHR.
对人口统计数据,SpA亚型,并发症和治疗方法的分析;使用精度,回忆和F-1分数进行绩效评估.

主要成果:

0.7%的医院人口 (4337名患者) 诊断为SPA.
该SPA队列主要是男性 (55.3%),平均年龄为50.9岁.
常见的并发病包括高血压 (25.0%) 和脂质失调 (22.2%). 甲托雷克萨特 (25.3%) 和阿达利穆马布 (10.6%) 是使用最多的药物. NLP表现出高精度和回忆能力 (F-1分数>0.80).

结论:

NLP技术有效地描述了SPA患者的个人资料,包括人口统计,并发症和治疗方法.
这项研究支持NLP在提高对SPA的理解方面的实用性.
通过从非结构化的EHR中提取有意义的数据,NLP有可能改善SPA患者的管理.

Genome-wide Association Studies-GWAS

Genome-wide Association Studies-GWAS

Genome-wide association studies or GWAS are used to identify whether common SNPs are associated with certain diseases. Suppose specific SNPs are more frequently observed in individuals with a particular disease than those without the disease. In that case, those SNPs are said to be associated with the disease. Chi-square analysis is performed to check the probability of the allele likely to be associated with the disease.
GWAS does not require the identification of the target gene involved in...

Rheumatic Heart Disease II: Clinical Manifestations and Diagnostic Studies

The key clinical manifestations of Rheumatic heart disease (RHD) include several distinct cardiac symptoms.Carditis, a hallmark of acute rheumatic fever, involves inflammation of the heart's endocardium, myocardium, and pericardium. Chronic RHD often results from recurrent episodes of carditis. Its symptoms include the following:Murmurs are caused by valvular damage, especially to the mitral and aortic valves. Mitral stenosis or regurgitation is common, with characteristic heart murmurs...
