概括
基因预测的情绪波动增加了患上胃肠道疾病的风险,包括上胃肠道,下胃肠道和肝胆道疾病. 这项研究强调了肠-大脑轴的连接,并表明情绪波动干预措施可能有助于治疗肠道疾病.
科学领域:
- 胃肠道学和精神病学
- 遗传学和流行病学
背景情况:
- 现有的研究将抑郁症和双相情感障碍等精神障碍与胃肠道 (GI) 疾病联系起来.
- 然而,情绪波动和胃肠道疾病之间的特定因果关系仍未得到充分研究.
- 人们越来越认识到肠-大脑轴在各种健康状况中的作用.
研究的目的:
- 探索情绪波动和胃肠道疾病之间的潜在因果关系.
- 利用门德尔的随机化 (MR) 方法来进行可靠的因果推理.
主要方法:
- 从最近的一项遗传研究中获得了与情绪波动相关的单核酸多态 (SNP).
- 来自FinnGen项目的24种胃肠道疾病的鉴定SNP.
- 使用逆方差加权 (IVW) 进行双向两样 MR 分析,并进行灵敏度和错误发现率 (FDR) 分析.
主要成果:
- 双向MR分析表明,情绪波动对发生肠胃疾病的风险有显著的因果关系 (OR: 1.213,P=3.490e-6).
- 情绪波动与24种胃肠道疾病中的11种疾病的风险增加有关,包括GERD,胃炎,IBS和NAFLD.
- 从肠道疾病到情绪波动没有发现显著的因果关系.
结论:
- 基因预测的情绪波动似乎是各种胃肠道疾病发展的危险因素.
- 针对情绪波动的干预措施可能为管理胃肠道疾病提供治疗途径.
- 这项研究强调了肠-大脑轴在消化健康中的重要性.

Cause and Effect
While variables are sometimes correlated because one does cause the other, it could also be that some other factor, a confounding variable, is actually causing the systematic movement in our variables of interest. For instance, as sales in ice cream increase, so does the overall rate of crime. Is it possible that indulging in your favorite flavor of ice cream could send you on a crime spree? Or, after committing crime do you think you might decide to treat yourself to a cone?
Other Disorders of Digestive System
The gastrointestinal tract is susceptible to various disorders. If the lower esophageal sphincter is damaged, stomach acid can flow back into the esophagus, causing irritation and inflammation of the lining. This condition is called gastroesophageal reflux disease (known as heartburn) and may cause chest pain and difficulty swallowing. In the stomach, prolonged use of nonsteroidal anti-inflammatory drugs like aspirin, chronic alcohol consumption, bacterial infections such as Helicobacter...
Assessment of the Gastrointestinal System I: Subjective Data
Assessing the gastrointestinal (GI) system is a complex process that begins with collecting subjective data. This data, collected through patient interviews, provides crucial insights into the patient's health history, perception patterns, and lifestyle habits, all contributing significantly to GI health.
Health History
The initial step in assessing the GI system is obtaining a comprehensive health history. This includes inquiring about the patient's history or presence of problems related to...

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.
The complex relationship between genetics and psychology is observable through common biological components such...

The Influence of Affect on Cognition
Positive affect significantly influences cognitive processes, including evaluation, memory, creativity, and social judgments. Compared to negative affect, positive emotional states promote more favorable interpretations of stimuli, cognitive flexibility, and heuristic processing. These effects highlight emotions' powerful role in shaping how individuals perceive, remember, and interact with the world.Influence on Evaluation and AttributionWhen individuals experience positive affect, they are...
Gut-Brain Axis
The gut–brain axis is a bidirectional communication system that connects the gastrointestinal tract and the brain. This interaction is mediated through multiple pathways, including the vagus nerve, hormonal signals, immune responses, and chemical messengers produced by gut microbes.Microbial Contributions to Brain FunctionGut microbiota contributes significantly to brain function by producing neuroactive compounds. These include neuroactive compounds that influence neurotransmitters such as...
