Risk of Incident Psychosis and Mania With Prescription Amphetamines

The American Journal of Psychiatry

This case-control study used electronic health records to examine the impact of dose levels of prescription amphetamines on the risk of incident psychosis and mania with prescription amphetamines. Among 1,374 case subjects and 2,748 control subjects, the odds of psychosis and mania were increased for individuals with past-month prescription amphetamine use compared with no use. A dose-response relationship was observed; high doses of amphetamines (>30 mg dextroamphetamine equivalents) were associated with 5.28-fold increased odds of psychosis or mania. Past-month methylphenidate use was not associated with increased odds of psychosis or mania compared with no use. Caution should be exercised when prescribing high doses of amphetamines, with regular screening for symptoms of psychosis or mania.

Cannabis Laws and Utilization of Medications for the Treatment of Mental Health Disorders  🔓

JAMA Network Open

This cross-sectional study of 9,438,716 commercially insured patients examined if access to cannabis, via medical or recreational legalization, is associated with changes in the dispensing of prescription medications to treat mental health disorders. Researchers found statistically significant reductions in benzodiazepine dispensing after increases in both medical and recreational cannabis access. However, evidence suggests increases in other types of psychotropic dispensing. The study suggests that cannabis laws may be significantly associated with the population-level use of prescription drugs to treat mental health disorders, although the associations vary by drug class and state.

State-level racial and ethnic disparities in buprenorphine treatment duration in the United States 

The American Journal on Addictions

National trends reveal a concerning escalation in racial and ethnic disparities in buprenorphine treatment duration for opioid use disorder. This study examined such disparities at the state level. Analyzing 9,040,620 buprenorphine prescriptions dispensed between January 2011 and December 2020 from IQVIA Longitudinal Prescription data, the study revealed substantial statewide variations in racial and ethnic disparities. Specifically, 21 states showed longer treatment durations for White people across all episodes, and 8 states displayed similar trends among episodes lasting ≥180 days. Longer treatment durations for White people in both overall and long-term episodes were exhibited in 5 states, and 15 states showed no racial and ethnic disparities.

Virtual reality-based Mindfulness-Oriented Recovery Enhancement (MORE-VR) as an adjunct to medications for opioid use disorder: a Phase 1 trial 🔓

Annals of Medicine

Mindfulness-Oriented Recovery Enhancement (MORE) uses mindfulness training to address dysregulation in brain reward systems. MORE has been shown to reduce drug cue reactivity and in an RCT reduced opioid misuse 45% at 9 months. Face-to-face MORE requires significant time of trained clinicians, and this study explored the feasibility of delivering MORE by virtual reality (VR). Treatment consisted of 8 weekly, one-hour MORE-VR sessions. Patients could choose the VR setting for their meditation (beach, forest, waterfall) and interact with virtual drugs and paraphernalia during session 5, which was devoted to examining and managing craving. Of 38 patients, 68% completed 4 or more sessions and 50% completed all sessions. Opioid use decreased significantly (p =.04), as well as craving (p<.001), and results showed a significant increase in positive affect (p<.001).

The Lancet Psychiatry Commission on youth mental health🔓

The Lancet Psychiatry

Mental ill health, which has been the leading health and social issue impacting the lives and futures of young people for decades, has entered a dangerous phase. Accumulating research evidence indicates that in many countries, the mental health of emerging adults has been declining steadily over the past two decades, with a major surge of mental ill health driven by the COVID-19 pandemic, the measures taken to contain it, and its aftermath. This alarming trend signals a warning that global megatrends (major, long-lasting societal changes such as environmental, social, economic, political, or technological changes) and changes in many societies around the world in the past two decades have harmed the mental health of young people and increased mental ill health among them.

Alcohol Consumption Patterns and Mortality Among Older Adults With Health-Related or Socioeconomic Risk Factors 

JAMA Network Open 

This British study included 135,103 older (median age 64) adults and compared drinking patterns with mortality during a median follow-up of 12 years. Compared to occasional drinkers, low-risk drinkers had higher cancer mortality (HR, 1.11), moderate-risk drinkers had higher all-cause and cancer mortality (HRs, 1.10 and 1.15), and high-risk drinking had higher all-cause, cancer, and cardiovascular mortality (HRs, 1.33, 1.39, and 1.21). These results contrast with earlier studies showing protective effects of low- to moderate-risk drinking. Researchers used occasional drinkers as the control group, where previous studies used abstainers including former drinkers with residual health effects. There was a small protective effect of drinking only with meals and drinking wine. In conclusion, the authors failed to find a protective effect of low-risk drinking on mortality.

Physician Reluctance to Intervene in Addiction: A Systematic Review

JAMA Network Open

This systematic review of 283 articles explored the reasons physicians give for not addressing substance use and addiction in their clinical practice. The institutional environment (81.2% of articles) was the most common reason given for physicians not intervening in addiction, followed by lack of skill (73.9%), cognitive capacity (73.5%), and knowledge (71.9%). These findings suggest that efforts should be directed at creating institutional environments that facilitate the delivery of evidence-based addiction care while improving access to education and training opportunities for physicians to practice the necessary skills.

Host Dr. Nick Athanasiou sat down with Drs. Matisyahu Shulman and Adam Bisaga to discuss the study they recently authored titled Rapid Initiation of Injection Naltrexone for Opioid Use Disorder: A Stepped-Wedge Cluster Randomized Trial. The doctors share their findings and the impact and implications of the study.

Social Vulnerability and Prevalence and Treatment for Mental Health and Substance Use Disorders

JAMA Psychiatry

This is a survey study of 4,674 participants from US households that examined the association between social vulnerability and mental health and substance use disorders and related treatment in the US noninstitutionalized population of adults aged 18 years and older. Large increases in several mental health and substance use disorders and corresponding decreases in treatment were found in the most socially vulnerable communities. The findings suggest that routine measurement of social vulnerability might assist in developing more comprehensive care models that integrate medical and social care for mental health and substance use disorders.

Psilocybin desynchronizes the human brain 

Nature

To assess how human brain network changes relate to the subjective and lasting effects of psychedelics, this study tracked individual-specific brain changes with longitudinal precision functional mapping (roughly 18 magnetic resonance imaging visits per participant). Psilocybin massively disrupted functional connectivity (FC) in the cortex and subcortex, acutely causing more than threefold greater change than methylphenidate. These FC changes were driven by brain desynchronization across spatial scales (areal, global), which dissolved network distinctions by reducing correlations within and anticorrelations between networks. Persistent reduction of hippocampal-default mode network connectivity may represent a neuroanatomical and correlate of the proplasticity and therapeutic effects of psychedelics.
