Journal of addiction medicine
|December 23, 2025
まとめ
メタンフェタミン関連死は全国的に増加しており、傾向と重症度には大きな地域差があります。一部の地域では安定化が見られるものの、死亡率は依然として高い水準にあり、個別化された公衆衛生介入が必要です。
科学分野:
- 公衆衛生
- 疫学
- 毒物学
背景:
- メタンフェタミン使用とそれに関連する死亡率は、米国における重大な公衆衛生上の課題を表しています。
- メタンフェタミン関連死の地理的および時間的パターンを理解することは、効果的な介入のために不可欠です。
研究 の 目的:
- 2005年から2023年までの米国国勢調査区分におけるメタンフェタミン関連死亡率の時間的推移を分析すること。
- メタンフェタミン関連死の発生率と進行における地理的ばらつきを特定すること。
主な方法:
- CDC WONDERデータベースを使用して死亡率データ(米国居住者15歳以上、2005-2023年)を利用しました。
- 人口10万人あたりの死亡率を国勢調査区分別に層別化して計算しました。
- Joinpoint回帰を使用して年間の変化率を評価し、有意な屈折点を特定しました。
主要な成果:
- メタンフェタミン関連死は、2005年から2023年の間に全区分で増加しました。
- 太平洋、南大西洋、山岳区分で累積死亡率が最も高くなりました。
- ニューイングランドと中部大西洋区分では割合は低いものの、急速な増加を経験しました。
- 一部の区分では、2021年以降、高い水準で安定化が見られました。
結論:
- メタンフェタミン関連死亡率は全国的に激化しており、タイミングと規模において重大な地理的格差が見られます。
- 一部の地域では、歴史的に高い水準で新たな安定化が見られます。
- 地域固有のハームリダクション、治療、予防戦略が不可欠です。

Phase II Reactions: Methylation Reactions
655
Methylation is a phase II biotransformation process involving the attachment of a methyl group to a substrate. Enzymes known as methyltransferases orchestrate this reaction.
The mechanism of methylation unfolds in two stages. The first stage sees a methyltransferase enzyme facilitating the transfer of a methyl group from S-adenosylmethionine (SAM) to the substrate, forming S-adenosylhomocysteine (SAH). The second stage involves further metabolism of SAH into homocysteine, which can be recycled...

Therapeutic Drug Monitoring: Affecting Factors
170
Therapeutic Drug Monitoring (TDM) is the clinical practice of measuring specific drug levels in a patient's blood or body tissues to manage and optimize therapy. TDM is crucial for drugs with narrow therapeutic windows, like warfarin and phenytoin, where incorrect doses can lead to treatment failure or severe side effects. This monitoring ensures the dosage administered is within a safe and effective range. The factors affecting therapeutic drug monitoring include:Patient-Specific Factors:a.

Drug Concentration Versus Time Correlation
1.9K
The plasma drug concentration-time curve is a crucial tool in pharmacokinetics, representing the drug's concentration in plasma at different time intervals post-administration. This curve illustrates the drug's journey from absorption into the systemic circulation, distribution to body tissues, and eventual elimination through excretion or biotransformation.
Two pivotal parameters are the minimum effective concentration (MEC) and the minimum toxic concentration (MTC). The MEC is the...

CNS Stimulants: Cocaine, Amphetamines and Cannabinoids
728
CNS stimulants, such as cocaine, amphetamines, and cannabinoids, have varying structures and mechanisms of action that lead to different therapeutic effects and side effects. Cocaine, with its molecular formula C17H21NO4, is a tropane alkaloid and a tertiary amino compound. It has two chemical forms: the hydrochloride salt and the "freebase." The former is in powder form, while the latter involves removing the hydrochloride salt to create a form that can be smoked. Cocaine exerts its...

Drug Regulation

Drug regulation encompasses the management of drug usage by evaluating its safety and efficacy through assessments conducted by regulatory authorities. Regrettably, the history of drug regulation is marred by several catastrophic events. One such incident is the Elixir Sulfanilamide tragedy, in which the toxic compound diethyl glycol was included in a sweet-tasting medication, leading to numerous fatalities. This event prompted the enactment of the Food, Drug, and Cosmetic Act in 1938. Under...

Stimulants

Stimulants are substances that enhance neural activity and elevate dopamine levels in the brain, leading to their highly addictive nature. These drugs include cocaine, amphetamines, MDMA, caffeine, and nicotine, each with distinct mechanisms of action and varied health implications.
Cocaine can be administered via snorting, injection, or smoking. It primarily functions by blocking the reuptake of dopamine, resulting in a euphoric high characterized by an intense sensation of happiness and...
