概括
与外围动脉疾病 (PAD) 相关的遗传变异也可以预测疾病的严重程度. 使用19种变异的多基因风险评分 (PRS) 显示,患有更严重PAD的患者,特别是需要手术的患者,得分更高.
科学领域:
- 遗传学 遗传学 是一个
- 心血管医学 心血管医学
- 流行病学 流行病学
背景情况:
- 周围动脉疾病 (PAD) 是致病率和死亡率的重要原因之一.
- 了解PAD严重程度的遗传贡献对于风险分层和治疗至关重要.
- 目前的研究往往侧重于PAD诊断,而不是疾病进展.
研究的目的:
- 调查19种已知的PAD相关遗传变异与PAD严重程度之间的关联.
- 开发和验证一个多基因风险评分 (PRS) 来预测PAD严重程度.
- 探索遗传风险与PAD严重程度的临床标志物之间的关系,包括诊断年龄和手术状态.
主要方法:
- 根据诊断年龄和手术干预,PAD病例被分为四个严重程度组.
- 基因关联分析使用REGENIE工具进行.
- 构建了一个19个变体的PRS,并对其与PAD严重程度亚型的关联进行了评估.
主要成果:
- 两个单核酸多态 (SNP),rs4722172和rs505922,与更严重的PAD亚型表现出更强烈的关联.
- 与非手术患者相比,在需要手术的患者中,19个变体的PRS显著升高 (OR=1.14,p=5.85×10−7).
- 在过早和非过早PAD发病之间没有观察到PRS的显著差异 (OR=0.98,p=0.64),这种模式在数据集中一致.
结论:

Histone Variants at the Centromere
5.1K
Histone variants are the histone proteins with structural and sequence variations. These variants may be regarded as “mutant” forms that replace their canonical histone counterparts in the nucleosomes. Specific post-translational modifications on the histone variants enable further chromatin complexity and regulate tissue-specific gene expression. The most common histone variants are from histone H2A, H2B, and linker histone H1 families. However, several variants of histone H3...

Nursing Interventions I: Taxonomy of Nursing Interventions
3.9K
Nursing interventions are chosen as part of the planning process to achieve patient outcomes. Once nursing diagnoses are determined, the goals and outcomes are specified, then the nursing interventions are selected and individualized according to the patient's situation.
A nursing intervention is a treatment or action based on scientific concepts and knowledge from the nursing, behavioral, and physical sciences. Identifying and prioritizing nursing interventions based on the desired outcome...

Nursing Interventions II: Selecting and Classifying the Nursing Interventions
3.4K
Creating and executing a nursing diagnosis helps nurses plan care and guide patient, family, and community interventions. They are developed based on a patient's physical evaluation and support measuring the outcomes. It is not recommended to select random interventions throughout the planning process. Instead, consider the following six essential factors when choosing interventions:

Community Based Intervention

Community-based interventions in mental health represent a paradigm shift from institution-centered care to treatments embedded within the fabric of local communities. By prioritizing inclusion and leveraging existing societal structures, this approach fosters a supportive environment conducive to addressing mental health challenges while promoting individual dignity and agency.

What is Population Genetics?
64.8K
A population is composed of members of the same species that simultaneously live and interact in the same area. When individuals in a population breed, they pass down their genes to their offspring. Many of these genes are polymorphic, meaning that they occur in multiple variants. Such variations of a gene are referred to as alleles. The collective set of all the alleles within a population is known as the gene pool.
