まとめ
有色人種はCUD臨床試験において過少代表であり、治療の適用性を制限している。人種差別のような独自の課題に対処する研究が行われておらず、多様な集団の効果的なCUDケアを妨げている。
科学分野:
- 臨床心理学; 公衆衛生; 薬物使用研究
背景:
- 有色人種は、大麻使用障害（CUD）の有病率と重症度が高いことを経験しています。; 人種差別は、マイノリティグループにおけるCUDの可能性の増加と関連しています。; 既存の研究では、有色人種が直面する独自の課題が見過ごされがちです。
研究 の 目的:
- CUDの行動医療におけるランダム化比較試験（RCT）への有色人種の包含を系統的にレビューすること。; CUD RCTにおける介入が、多様な人種グループの特定のニーズと課題に対処しているかを評価すること。
主な方法:
- PubMed、PsycINFO、およびClinicalTrials.govで、米国を拠点とする成人CUD行動医療RCTの系統的検索を実施しました。; 特定された14のRCT（1994-2025）の参加者の人種人口統計と介入デザインを分析しました。; 包含基準は、成人におけるCUDを対象とした研究に焦点を当てました。
主要な成果:
- 白人参加者は約64%を占め、CUD有病率を大幅に上回る割合で含まれていました。; 有色人種は著しく過少代表でした：黒人（約19%）、ラテン系（5%）、アジア系（0.6%）、先住民（0.4%）、および複数人種/その他（0.8%）。; 文化的な適応や人種差別のような独自の課題に対処する介入を報告した研究はありませんでした。; 多様性は時間とともに改善していません。
結論:
- CUD RCTにおける有色人種の著しい過少代表は、研究の一般化可能性と治療の適用性を制限します。; 文化的に適応された介入の欠如は、セラピストが多様な患者集団の完全なニーズを満たす能力を妨げる可能性があります。; 多様性への呼びかけにもかかわらず、CUD RCTにおける人種的包含は依然として危機的に低く、変化の緊急の必要性を浮き彫りにしています。

Often, psychologists develop surveys as a means of gathering data. Surveys are lists of questions to be answered by research participants, and can be delivered as paper-and-pencil questionnaires, administered electronically, or conducted verbally. Generally, the survey itself can be completed in a short time, and the ease of administering a survey makes it easy to collect data from a large number of people.

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.

01:21Chemotherapy-Induced Nausea and Vomiting: Cannabinoids
649
Tetrahydrocannabinol (THC) is a phytocannabinoid that primarily interacts with the CB1 receptor, a type of G protein-coupled receptor (GPCR) predominantly in and around the chemoreceptor trigger zone (CTZ) and emetic center. THC also blocks the serotonin receptor activity in the dorsal vagal complex (DVC) by inhibiting serotonin release. THC exerts its anti-emetic effects through these interactions, which are beneficial for patients undergoing chemotherapy.

Humans are very diverse and although we share many similarities, we also have many differences. The social groups we belong to help form our identities (Tajfel, 1974). These differences may be difficult for some people to reconcile, which may lead to prejudice toward people who are different. Prejudice is a negative attitude and feeling toward an individual based solely on one’s membership in a particular social group (Allport, 1954; Brown, 2010). Prejudice is common against people who...

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...

Archaea, a domain of single-celled microorganisms, are classified into five major phyla based on genetic and biochemical characteristics: Euryarchaeota, Crenarchaeota, Thaumarchaeota, Korarchaeota, and Nanoarchaeota. Among these, the phylum Euryarchaeota is notable for its remarkable diversity in morphology, metabolism, and ecological adaptations.Morphological and Metabolic DiversityMembers of Euryarchaeota exhibit a variety of cellular shapes, including rods and cocci. Their metabolic pathways...
