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...

科学领域:

老年学和老年医学是老年学和老年医学.
公共卫生和流行病学
慢性疾病管理慢性疾病管理

背景情况:

多病症,定义为两个或两个以上的慢性疾病,影响约50%的美国老年人.
后果包括增加对疾病的脆弱性,疾病恶化,住院治疗和更高的医疗费用.
早期识别风险因素对于医疗保健决策和预防不良结果至关重要.

研究的目的:

使用快速老年评估 (RGA) 工具检查老年人多病症和特定老年综合征的存在.
评估RGA作为在不同实践环境中多病症查工具的有效性.

主要方法:

一项涉及密苏里州65岁及以上16,615名个人 (2015-2024) 的横截面研究.
快速老年评估 (RGA) 工具进行了管理,评估了四种老年综合征:虚弱,,老年性厌食症和认知衰退.
使用后勤回归分析来确定老年综合征和多病症 (定义为五种或更多疾病) 之间的关联.

主要成果:

37.3%的参与者报告患有五种或更多疾病 (多重疾病).
萨科佩尼亚与多病症严重相关 (OR=3.807,p < 0.001).
老年性厌食症 (OR=1.329,p < 0.001) 和痴呆症 (OR=1.273,p < 0.001) 也与多发病率更高的几率显著相关.

结论:

快速 Geriatric 评估 (RGA) 工具是有效的查工具,用于识别多病症的老年人.
老年综合征,特别是肉症,老年性厌食症和痴呆症,是多发症的重要危险因素.
这些综合征的早期发现和管理对于预防老年人群进一步发病和残疾至关重要.
