概括
使用被动样本的基于废水的流行病学没有显示出澳大利亚偏远地区的药物消费水平有显著差异,除了主要城市的可卡因使用率更高. 药物使用趋势各不相同,观察到氧化,可卡因和甲基胺的减少.
科学领域:
- 环境科学 环境科学
- 公共卫生 公共卫生
- 法医化学 法医化学
背景情况:
- 以废水为基础的流行病学 (WBE) 传统上使用昂贵的自动采样器,限制其到达主要的废水处理厂 (WWTP).
- 这造成了区域性,偏远地区和低收入国家的毒品消费数据差距.
- 被动采样器为WBE提供了具有成本效益的替代方案.
研究的目的:
- 用被动样本估计和调查澳大利亚不同程度的偏远地区的毒品消费趋势.
- 评估被动采样的可行性,以便将WBE计划扩展到服务不足的地区.
主要方法:
- 在澳大利亚43个处理厂部署了经过现场校准的微孔聚乙烯被动采样器,遍及五个偏远类别.
- 在两个时期 (2019年8月/9月和2020年) 收集样本.
- 估计人均消费的可卡因,甲基胺,尼古丁, oxycodone 和 MDMA.
主要成果:
- 除了可卡因之外,在偏远地区的各个水平上,没有观察到毒品消费的空间趋势,在主要城市中,可卡因的消费量是5至10倍.
- 外部地区的网站显示了最高和最低的甲基胺类药物消费.
- 与主要城市相比,偏远地区的药物使用差异更高.
- 在2019年至2020年期间,在所有地点都注意到氧化消费的显著下降.
- 大多数地点的可卡因和甲基胺消费量有所减少.
结论:
- 被动采样对于将基于废水的药物监测扩展到包括偏远地区在内的不同地理位置是有效的.
- 与区域和偏远地区相比,澳大利亚主要城市的可卡因消费量明显高.
- 观察到的药物消费下降可能与监管变化,COVID-19大流行以及供需动态有关.

Drug Dependence
1.1K
Medications are typically administered to achieve therapeutic effects. Some drugs can modify an individual's mood and perception, frequently resulting in various enjoyable experiences. However, this can result in drug dependency, a condition marked by continuous drug use despite potential negative consequences. Drug dependency primarily falls into two categories: psychological and physical dependence. Psychological dependence occurs when the pleasurable feelings induced by the drug...

Drug Delivery: Miscellaneous Routes
381
Drug delivery methods like oral inhalation, nasal sprays, transdermal patches, eye drops, intravitreal injection, and rectal administration provide localized effects with reduced toxicity.
Oral inhalation and nasal sprays swiftly transfer drugs across the respiratory epithelium's mucosal layer. Inhaled glucocorticoids and bronchodilators directly target lung conditions such as asthma, while fluticasone nasal spray mitigates allergic rhinitis.

Substance Use Disorders Affecting Sleep
196
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.

Factors Affecting Drug Response: Overview
2.0K
When it comes to infants and young children, they are typically administered smaller doses of medication in comparison to adults. This is primarily because their organ functions still need to fully develop, meaning their bodies are not as efficient at metabolizing or eliminating drugs. Additionally, their blood-brain barrier is more permeable than in adults. As a result, high concentrations of drugs can easily penetrate the central nervous system (CNS), potentially leading to neurological...

Factors Affecting Drug Distribution: Miscellaneous Factors
379
Drug distribution in the human body is a complex process influenced by various individual factors, including age, pregnancy, obesity, diet, body water composition, pH levels, and specific disease conditions.
Age plays a significant role due to differences in body composition among different age groups. Infants, for instance, have a higher proportion of total body water and lower albumin levels, a protein that binds drugs in the bloodstream. This unique composition in infants enhances the...

Drug Distribution: Overview
211
Drug distribution within the body is a dynamic process involving the movement of a drug in two directions across various compartments: from the bloodstream into tissues (tissue uptake) and from tissues back into the bloodstream (tissue release or redistribution). This process is passive and primarily driven by two variables: the concentration gradient between the bloodstream and the extravascular tissues and the drug's ability to cross the cell membrane.
