Privacy, Care-seeking, and Stigma: A Qualitative Investigation of Patient Perspectives on Sharing Substance Use Disorder Treatment Records.

Objectives: To examine, among persons with substance use disorders (SUDs), how their decision-making to seek care is influenced by concerns about the privacy of their treatment records, how they weigh the risks and benefits of record sharing, and their awareness of how records are shared and regulated.

Methods: This qualitative study followed the Standards for Reporting Qualitative Research and analyzed semi-structured interviews of 13 men and 14 women recruited from inpatient and residential SUD treatment programs. Due to the onset of the COVID-19 pandemic, recruitment took place over an extended period (between May 2020 and July 2023).

Examining the Severity and Progression of Illicitly Manufactured Fentanyl Withdrawal: A Quasi-experimental Comparison.

Objective: Illicitly manufactured fentanyl has largely replaced heroin throughout the United States. Characteristics of fentanyl-specific withdrawal are not well understood compared to traditional opioid withdrawal. This study examines opioid withdrawal severity among 2 cohorts of study participants who underwent identical morphine stabilization procedures before and after fentanyl was introduced to the local drug market.

The Concept of Treatment-Refractory Addiction: A Call to the Field.

Not all patients respond to effective and approved treatment interventions, and there has been growing recognition in the medical field of these "resistant" or refractory illnesses (eg, treatment-resistant depression, resistant hypertension). In the field of substance use disorders, there has not been an explicit acknowledgement of treatment-refractory addiction (TRA) despite substantial evidence that many patients do not respond to standard-of-care treatment interventions. This article provides a justification for TRA as a critically important condition to recognize and define.

Examining NSDUH's Assessment of Fentanyl Use: A Comparison of Trends in Fentanyl Use and Fentanyl Overdose Deaths From 2015 to 2020.

Objective: The National Survey on Drug Use and Health (NSDUH), as the primary source of epidemiological substance use data in the United States, could illuminate trends in fentanyl use behaviors contributing to the opioid overdose crisis. We hypothesized that the trend in NSDUH prevalence of lifetime fentanyl injection would match the direction and magnitude of the trend in synthetic opioid overdose deaths.

Method: Using logistic regression, we modeled the 2015-2020 trend in synthetic opioid overdose deaths as a proportion of all deaths.

Virtual focus groups among individuals with use disorders: assessing feasibility and acceptability in an underserved clinical population.

Objective: There are substantial barriers to conducting research among individuals with stigmatized and complicated health conditions like substance use disorders. These barriers slow progress when developing, refining, and assessing interventions to better treat underserved populations. Virtual focus groups are an innovative method for collecting data from individuals via a discreet and accessible platform which can inform novel as well as existing treatment approaches.

Establishing a research agenda for the study and assessment of opioid withdrawal.

The opioid crisis is an international public health concern. Treatments for opioid use disorder centre largely on the management of opioid withdrawal, an aversive collection of signs and symptoms that contribute to opioid use disorder. Whereas in the past 50 years more than 90 medications have been developed for depression, only five medications have been developed for opioid use disorder during this period.

Suvorexant alters dynamics of the sleep-electroencephalography-power spectrum and depressive-symptom trajectories during inpatient opioid withdrawal.

Study Objectives: Opioid withdrawal is an aversive experience that often exacerbates depressive symptoms and poor sleep. The aims of the present study were to examine the effects of suvorexant on oscillatory sleep-electroencephalography (EEG) band power during medically managed opioid withdrawal, and to examine their association with withdrawal severity and depressive symptoms.

Methods: Participants with opioid use disorder (N = 38: age-range:21-63, 87% male, 45% white) underwent an 11-day buprenorphine taper, in which they were randomly assigned to suvorexant (20 mg [n = 14] or 40 mg [n = 12]), or placebo [n = 12], while ambulatory sleep-EEG data was collected.

Polymorphisms in the A118G SNP of the OPRM1 gene produce different experiences of opioids: A human laboratory phenotype-genotype assessment.

Allelic variations in the A118G SNP of the OPRM1 gene change opioid signaling; however, evaluations of how allelic differences may influence opioid effects are lacking. This human laboratory paradigm examined whether the AA versus AG/GG genotypes determined opioid response profiles. Individuals with limited opioid exposure (N = 100) completed a five-day within-subject, double-blind, placebo-controlled, residential study.

Functional imaging studies of acute administration of classic psychedelics, ketamine, and MDMA: Methodological limitations and convergent results.

Functional magnetic resonance imaging (fMRI) is increasingly used to non-invasively study the acute impact of psychedelics on the human brain. While fMRI is a promising tool for measuring brain function in response to psychedelics, it also has known methodological challenges. We conducted a systematic review of fMRI studies examining acute responses to experimentally administered psychedelics in order to identify convergent findings and characterize heterogeneity in the literature.

Control Conditions in Randomized Trials of Psychedelics: An ACTTION Systematic Review.

To systematically review control conditions of all available randomized psychedelic trials. We searched PubMed, PsycINFO, and EMBASE for randomized trials of psychedelics in humans from 1940 through May 2020 with no language restrictions. PRISMA guidelines were followed.

Operational definition of precipitated opioid withdrawal.

Background: Opioid withdrawal can be expressed as both a spontaneous and precipitated syndrome. Although spontaneous withdrawal is well-characterized, there is no operational definition of precipitated opioid withdrawal.

Methods: People ( = 106) with opioid use disorder maintained on morphine received 0.

Clinical Trial Design Challenges and Opportunities for Emerging Treatments for Opioid Use Disorder: A Review.

Importance: Novel treatments for opioid use disorder (OUD) are needed to address both the ongoing opioid epidemic and long-standing barriers to existing OUD treatments that target the endogenous μ-opioid receptor (MOR) system. The goal of this review is to highlight unique clinical trial design considerations for the study of emerging treatments for OUD that address targets beyond the MOR system. In November 2019, the Analgesic, Anesthetic, and Addiction Clinical Trial Translations, Innovations, Opportunities, and Networks (ACTTION) public-private partnership with the US Food and Drug Administration sponsored a meeting to discuss the current evidence regarding potential treatments for OUD, including cannabinoids, psychedelics, sedative-hypnotics, and immunotherapeutics, such as vaccines.

Suvorexant ameliorated sleep disturbance, opioid withdrawal, and craving during a buprenorphine taper.

Increased orexin/hypocretin signaling is implicated in opioid withdrawal, sleep disturbances, and drug-seeking behaviors. This study examined whether a dual-orexin receptor antagonist would improve sleep and withdrawal outcomes when compared with placebo during a buprenorphine/naloxone taper. Thirty-eight participants with opioid use disorder were recruited to a clinical research unit and maintained on 8/2 to 16/4 mg of buprenorphine/naloxone treatment for 3 days before being randomized to 20 mg of suvorexant ( = 14), 40 mg of suvorexant ( = 12), or placebo ( = 12); 26 individuals completed the study.

Patient-reported sleep outcomes in randomized-controlled trials in persons with substance use disorders: A systematic review.

Background: Sleep disturbances and disorders are a common and sometimes recalcitrant problem in persons recovering from substance use disorders (SUDs). As such, several randomized-controlled trials (RCTs) have been conducted to address sleep disturbances in a variety of SUD subpopulations and clinical scenarios. The goal of this systematic review was to collate patient-reported sleep outcomes used in past SUD-related RCTs to provide guidance for future sleep research in persons with SUDs.

Objective sleep outcomes in randomized-controlled trials in persons with substance use disorders: A systematic review.

Background: Improving sleep health is an important target for substance use disorder (SUD) research. However, there is little guidance for SUD researchers regarding the use of technologies to objectively assess sleep outcomes in randomized-controlled trials (RCTs). This systematic review aimed to describe the use of technologies to objectively measure sleep outcomes in RCTs conducted in persons with SUDs, in order to inform future sleep intervention studies in SUD populations.

If the Doors of Perception Were Cleansed, Would Chronic Pain be Relieved? Evaluating the Benefits and Risks of Psychedelics.

Psychedelic substances have played important roles in diverse cultures, and ingesting various plant preparations to evoke altered states of consciousness has been described throughout recorded history. Accounts of the subjective effects of psychedelics typically focus on spiritual and mystical-type experiences, including feelings of unity, sacredness, and transcendence. Over the past 2 decades, there has been increasing interest in psychedelics as treatments for various medical disorders, including chronic pain.

Gender parity and homophily in the Drug and Alcohol Dependence editorial process.

Background: Despite efforts towards gender parity and some improvement over time, gender bias in peer review remains a pervasive issue. We examined gender representation and homophily in the peer review process for Drug and Alcohol Dependence (DAD).

Methods: We extracted data for papers submitted to DAD between 2004 and 2019, inclusive.

A comparison of registered and published primary outcomes in clinical trials of opioid use disorder: ACTTION review and recommendations.

Background And Aims: Prospective trial registration can increase research integrity. This Analgesic, Anesthetic, and Addiction Clinical Trial Translations, Innovations, Opportunities, and Networks (ACTTION) review was designed to compare the primary outcomes (PO) reported in registries with associated publications for opioid use disorder (OUD) clinical trials.

Design: The World Health Organization's International Clinical Trials Registry Platform (ICTRP) was searched for completed trials (2010 through 2019).

Characterization of basal ganglia volume changes in the context of HIV and polysubstance use.

HIV and psychoactive substances can impact the integrity of the basal ganglia (BG), a neural substrate of cognition, motor control, and reward-seeking behaviors. This study assessed BG gray matter (GM) volume as a function of polysubstance (stimulant and opioid) use and HIV status. We hypothesized that comorbid polysubstance use and HIV seropositivity would alter BG GM volume differently than would polysubstance use or HIV status alone.
