|November 28, 2024
概括
很少有酒精使用障碍 (AUD) 的个人寻求治疗. 这项研究发现,虽然临床因素是关键预测因素,但将AUD遗传风险的多基因得分 (PGS) 纳入其中并没有显著改善寻求治疗的预测,尽管它对年轻人更有影响力.
科学领域:
- 精神病学是一个精神病学.
- 遗传学 遗传学 是一个
- 机器学习 机器学习
背景情况:
- 酒精使用障碍 (AUD) 影响了许多人,但很少有人接受治疗.
- 以前的研究发现,饮酒行为,心理问题和物质依赖是寻求治疗的预测因素.
- 之前的研究还没有将多基因分数 (PGS) 作为AUD遗传风险的衡量标准纳入寻求治疗的预测模型.
研究的目的:
- 预测患有AUD的个体寻求治疗的行为.
- 调查AUD临床表型和多基因分数 (PGS) 对寻求治疗的预测价值.
- 检查年龄对PGS对AUD治疗寻求预测能力的影响.
主要方法:
- 利用耶鲁-宾夕法尼亚大学的样本,确定了9,103名DSM-IV AUD和寻求治疗状态的个人.
- 使用随机森林 (RF) 模型与91个临床相关的表型来预测寻求治疗.
- 对非洲 (AFR) 和欧洲 (EUR) 血统的个人计算的AUD PGS,开发带有和没有PGS的射频模型,按年龄分层 (<40和≥40).
主要成果:
- 66.6%的样本报告寻求治疗;主要预测因素包括酒精使用时间,心理问题,精神病诊断和心脏病.
- 没有PGS的模型实现了EUR的79.8%准确率 (0.85AUC) 和AFR的75%准确率 (0.78AUC);添加PGS并没有显著改变性能.
- 与老年人相比,PGS在年轻人中是一个更重要的预测因素 (欧元:第8个<40;AFR:第14个<40) 与老年人相比 (欧元:第48个≥40;AFR:第24个≥40).
结论:
- 酒精使用,精神问题和并发性疾病是寻求AUD治疗的重要预测因素.
- 纳入AUD多基因分数 (PGS) 并没有大大提高预测准确性,但突出了遗传风险的作用,特别是在年轻人群中.
- 机器学习模型有效地预测了使用临床数据寻求治疗的情况,PGS提供了对影响治疗参与的遗传倾向的补充洞察.

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.

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.

Substance Use Disorders Affecting Sleep

Substance use disorders involve a pattern of using drugs more extensively than intended and continuing use despite harmful consequences. This includes legal substances like alcohol and nicotine, as well as illegal drugs. These disorders often involve both physical and psychological dependence, reflecting compulsive use of substances that significantly alter thoughts, feelings, and behaviors, contributing to a major public health issue.
