概括

现象广泛关联研究 (PheWAS) 确定了新型风险因素和黄金葡萄球菌感染 (SAI) 的并发症. 这项研究引入了一种两阶段的PheWAS方法,用于发现疾病与疾病之间的相互作用.

科学领域:

遗传学和基因组学遗传学和基因组学
流行病学流行病学
临床信息学临床信息学

背景情况:

现象广泛关联研究 (PheWAS) 系统地选医疗记录以寻找表型关联.
之前没有对与黄金葡萄球菌感染 (SAI) 相关的表型进行系统查.
潜在的新风险因素和SAI的并发症仍然未被发现.

研究的目的:

使用量身定制的两阶段PheWAS方法,识别与金黄色葡萄球菌感染 (SAI) 相关的新型表型.
发现SAI的新风险因素和并发症.
在独立的患者队列中验证新的关联.

主要方法:

开发了一种两阶段的PheWAS选程序.
第一阶段涉及查SAI与其他表型的同时发生.
第二阶段检查了发病年龄的相关性;分析使用了马什菲尔德诊所卫生系统数据 (754,401名患者) 和TriNetX (109,884,571名患者) 和All of Us (118,538名患者) 队列中的验证结果.

主要成果:

41种表型符合显著性标准 (p值<3.64e-5,或>5).
23个关联被归类为SAI的风险因素或并发症.
发现了三个新的关联:长期使用阿司匹林 (风险),缺铁性贫血和慢性疾病 (并发症) 的贫血,在验证队列中复制.

结论:

高等教育机构的PheWAS增强了对相互作用的表型的理解.
新的两阶段PheWAS方法可应用于其他疾病相互作用研究.
这些发现需要进一步调查,因为可能存在观察数据偏差.

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...

Skin Diseases and Disorders

Skin Diseases and Disorders

Skin is the first line of defense and encounters a variety of microbes. Some pathogenic strains are often the cause of a broad range of infections of the skin and other body systems. These conditions can affect people of all ages and may have different causes, including genetic factors, infections, autoimmune reactions, environmental factors, and lifestyle choices.
Gram-positive Staphylococcus spp. and Streptococcus spp. are responsible for many of the most common skin infections. However, many...
