概括
电子健康记录 (EHR) 数据集成用于罕见疾病研究受到国际疾病分类 (ICD) 和人类表型本体学 (HPO) 之间的不良调整的阻碍. 这些关键本体学之间的有限映射限制了数据互操作性.
科学领域:
- 生物医学信息学 生物医学信息学
- 临床数据管理 临床数据管理
- 罕见疾病研究 罕见疾病研究
背景情况:
- 整合电子健康记录 (EHR) 数据与多种资源对于罕见疾病研究至关重要,因为患者患病率低.
- 数据整合严重依赖于用于注释的本体学的语义对齐,特别是临床诊断的疾病国际分类 (ICD) 和表型的人类表型本体 (HPO).
- ICD和HPO之间的互操作性和重叠程度在很大程度上仍未得到量化,这对有效的数据链接构成了挑战.
研究的目的:
- 调查国际疾病分类 (ICD) 和人类表型本体学 (HPO) 之间的对齐和互操作性.
- 评估现有的调整是否有助于将电子健康记录 (EHR) 数据与研究本体学的整合.
- 量化ICD和HPO之间的映射覆盖范围在统一医疗语言系统 (UMLS) 的元词汇库和现实世界EHR数据集中.
主要方法:
- 使用UMLS Metathesaurus进行了ICD和HPO之间的映射覆盖范围的经验分析.
- 将映射覆盖范围解释为替代性,以方便将临床数据与HPO等研究本体学集成.
- 在现实世界EHR数据集中,量化了与HPO术语映射的ICD代码的比例.
主要成果:
- 在UMLS Metathesaurus中,只有2.2%的ICD代码有直接映射到HPO.
- 在分析的EHR数据集中,不到50%的ICD代码具有与HPO术语的映射.
- 在EHR数据中经常使用的ICD代码显示HPO的映射率更高,而较罕见的疾病的代码很少被映射.
结论:
- ICD和HPO之间的互操作性,特别是通过UMLS,是非常有限的.
- 虽然存在补充映射资源,但没有标准化的公约,用于提高基于UMLS的对齐.
- 这些发现突出了利用EHR数据用于罕见疾病研究的重大挑战,原因是本体学互操作性差.

Genome-wide Association Studies-GWAS
12.5K
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.

Incomplete Dominance
21.6K
Gregor Mendel's work (1822 - 1884) was primarily focused on pea plants. Through his initial experiments, he determined that every gene in a diploid cell has two variants called alleles inherited from each parent. He suggested that amongst these two alleles, one allele is dominant in character and the other recessive. The combination of alleles determines the phenotype of a gene in an organism.

Human Genetics

Human genetics provides a profound framework for understanding the interplay between genetic predispositions and human psychology. At the heart of this discipline lies the study of how genes influence physical traits, behaviors, and susceptibility to diseases. Each person carries a unique genetic code that subtly or significantly shapes their psychological and behavioral landscape.

Pleiotropy
39.9K
Pleiotropy is the phenomenon in which a single gene impacts multiple, seemingly unrelated phenotypic traits. For example, defects in the SOX10 gene cause Waardenburg Syndrome Type 4, or WS4, which can cause defects in pigmentation, hearing impairments, and an absence of intestinal contractions necessary for elimination. This diversity of phenotypes results from the expression pattern of SOX10 in early embryonic and fetal development. SOX10 is found in neural crest cells that form melanocytes,...

Formulating and Validating Nursing Diagnosis I
2.6K
A nursing diagnosis is written when the nurse recognizes a cluster of essential patient data indicating health problems treated with independent nursing interventions. The standardized terminologies of a nursing diagnosis help nurses identify and treat patients' problems. Every electronic health record that uses nursing diagnosis must employ standard diagnostic terminology. Developing an efficient, individualized care plan begins with accurate nursing diagnoses.
