概括

大麻使用障碍 (CUD) 与口腔微生物群的显著变化有关,包括减少多样性和改变细菌组成. 大麻的大量使用与这些微生物的转变特别相关.

科学领域:

微生物学微生物学
公共卫生公共卫生
成药物药物药物药物

背景情况:

大麻使用障碍 (CUD) 是一个日益严重的公共卫生问题,特别是在年轻人中.
口腔微生物组在整体健康中的作用是显著的,但其与CUD的联系还没有得到充分研究.
了解CUD的口腔微生物特征可能会揭示生物机制和治疗点.

研究的目的:

调查CUD和口腔微生物组之间的联系.
将CUD患者的口腔微生物概况与其他物质使用障碍 (SUD) 患者的口腔微生物概况进行比较.
探索大麻使用模式和口腔微生物变化之间的关系.

主要方法:

16S rRNA基因测序被用来分析来自CUD和非CUDSUD的对照组的年轻成年 (18-25岁) 的唾液样本.
在不同组之间比较了α多样性,β多样性和种群丰度.
在CUD组中,研究了大麻使用频率/数量和微生物特征之间的关联.

主要成果:

与非CUD SUD组相比,患有CUD的个体表现出明显较低的α多样性和明显的β多样性.
在CUD和对照组之间观察到口腔种群丰度的特定差异.
较高的大麻使用频率与较低的口腔微生物多样性相关,频率和数量都与严格无气体的增加有关.

结论:

可证明,CUD与口腔微生物组的特定变化有关,其特点是减少多样性和分类学转变.
这些发现突出了频繁和大量使用大麻对口腔微生物组成的影响.
需要进一步的研究来阐明这些CUD相关的口腔微生物组变化的功能后果.

Serum Laboratory Studies, Stool Test, Breath Test

Gastrointestinal (GI) diagnostic studies are pivotal in confirming, ruling out, diagnosing, or staging various diseases, including cancers. Following diagnosis, allocating time for discussions with the patient and providing informational resources is crucial. Diagnostic assessments of the GI tract often occur in outpatient settings like endoscopy suites or GI labs. Preparation for these tests may include dietary restrictions, fasting, liquid bowel preparations, laxatives, enemas, and the...

Substance Use Disorders Affecting Sleep

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.
Understanding the concepts of physical dependence,...
