BACKGROUND: Increasing reports of synthetic cannabinoid (SC)-related adverse events have largely comprised case reports and analyses of calls to poison control centers. Existing studies have also mostly involved white male populations. OBJECTIVES: The purpose of this study is to systematically describe clinical characteristics of SC use in a relatively large, diverse, urban sample presenting to a psychiatric emergency setting. METHODS: SC users (n = 110) were identified by reviewing charts (n = 948) from the psychiatric emergency service of a large, urban public hospital in the United States for November 2014, which was randomly selected from the 12 months of that year. Sociodemographic data were collected from administrative databases and clinical data were collected from the electronic medical record. RESULTS: SC users were mostly non-white (90.0%) males (95.5%), who were likely to be police-involved (34.5%) and homeless (84.5%). SC users also had significant and often pre-existing psychiatric and substance use comorbidity, including acute psychotic symptoms (70.0%), more than one comorbid psychiatric diagnosis (31.8%) and primary psychotic disorder diagnosis (40.0%), past psychiatric visits to the hospital (70.9%), comorbid substance use (62.7%), agitation requiring intervention (22.7%), and the need for extended psychiatric observation (15.5%) and inpatient admission (34.5%). Relatively limited medical complications were identified. Conclusions/Importance: In this sample, SC use affected a sociodemographically disadvantaged and mentally ill population, likely exacerbating existing psychiatric problems. This is one of the only studies to systematically examine the clinical effects of SC use in a significant clinical sample, and the first study in an urban, racial/ethnic minority, and vulnerable sample.

BACKGROUND: Alcohol and drug use is a leading cause of morbidity and mortality that frequently goes unidentified in medical settings. As part of a multi-phase study to implement the NIDA Common Data Elements for collecting substance use screening information in electronic health records (EHRs), we interviewed key clinical stakeholders with a goal of identifying barriers and facilitators affecting the implementation of substance use screening in primary care clinics. METHODS: Focus groups and individual qualitative interviews were conducted with 67 stakeholders, including primary care patients, medical providers (faculty and resident physicians, nurses), and medical assistants, in two urban academic health systems. Themes were identified, discussed, and revised through an iterative process, and mapped to the Knowledge to Action (KTA) framework (Graham, 2006), which guides the selection and implementation of new clinical practices. RESULTS: Factors affecting implementation based on KTA elements were identified from participant narratives. Identifying the problem: Participants unanimously agreed that having knowledge of a patient's substance use is important because of its impacts on health andmedical care, that substance use is not properly identified in medical settings, and that universal screening is the best approach. Adapting knowledge: The majority of patients and providers stated that the primary care provider should play a key role in substance use screening and interventions. There was discrepancy of opinion regarding the optimal approach to delivering screening. Some felt that patients should self-administer questionnaires, while others thought that patients would be more comfortable having face-to-face discussions with their primary care provider - though not with other members of the care team. Many providers reported that being able to take effective action once unhealthy substance use is identified is crucial. Assessing barriers: Patients expressed concerns about confidentiality, 'denial', and providers' lack of empathy. Barriers identified by providers included individual-level factors such as lack of knowledge and training, and systems-level factors including lack of time, resources, and space, disjointed communication between members of the medical team, and difficulty accessing addiction treatment. CONCLUSIONS: Based on these findings, we designed and are testing an implementation strategy utilizing universal screening, patient self-administered questionnaires, and EHR-integrated clinical decision support to assist providers in conducting brief motivational counseling and linking patients to behavioral health services, to address unhealthy substance use in primary care clinics

The number of network members and the roles they play can influence risk behaviors and consequently intervention strategies to reduce HIV transmission. We recruited 652 people who use drugs (PWUD) from socially disadvantaged neighborhoods in New York City (07/2006-06/2009). Interviewer-administered surveys ascertained demographic, behavioral, and network data. We used logistic regression, stratified by exchange sex, to assess the relationship between HIV status and the number of network members with different roles, treated as independent and multiplex (i.e., drug + sex). Those with more multiplex risk ties were significantly more likely to be HIV positive, but only among those not reporting exchange sex (AOR = 3.2). Among those reporting exchange sex, men reporting recent male sex partners were more likely to report HIV positive status (AOR = 12.6). These data suggest that sex and drug relationships among PWUD are interrelated. Interventions that target multiplex rather than single-role relationships may be more effective in influencing behavior change.

OBJECTIVES: This report identifies the institutional barriers to, and benefits of, buprenorphine maintenance treatment (BMT) integration in an established hospital-based opioid treatment program (OTP). METHODS: This case study presents the authors' experiences at the clinic, hospital, and corporation levels during efforts to integrate BMT into a hospital-based OTP in New York City and a descriptive quantitative analysis of the characteristics of hospital outpatients treated with buprenorphine from 2006 to 2013 (N=735). RESULTS: Integration of BMT into an OTP offered patients the flexibility to transition between intensive structured care and primary care or outpatient psychiatry according to need. Main barriers encountered were regulations, clinical logistics of dispensing medications, internal cost and reimbursement issues, and professional and cultural resistance. CONCLUSIONS: Buprenorphine integration offers a model for other OTPs to facilitate partnerships among primary care and mental health clinics to better serve diverse patients with varying clinical needs and with varying levels of social support.

Chronic food restriction potentiates behavioral and cellular responses to drugs of abuse and D-1 dopamine receptor agonists administered systemically or locally in the nucleus accumbens (NAc). However, the alterations in NAc synaptic transmission underlying these effects are incompletely understood. AMPA receptor trafficking is a major mechanism for regulating synaptic strength, and previous studies have shown that both sucrose and d-amphetamine rapidly alter the abundance of AMPA receptor subunits in the NAc postsynaptic density (PSD) in a manner that differs between food-restricted and ad libitum fed rats. The present study examined whether food restriction, in the absence of reward stimulus challenge, alters AMPAR subunit abundance in the NAc PSD. Food restriction was found to increase surface expression and, specifically, PSD abundance, of GluA1 but not GluA2, suggesting synaptic incorporation of GluA2-lacking Ca2+-permeable AMPARs (CP-AMPARs). Naspm, an antagonist of CP-AMPARs, decreased the amplitude of evoked EPSCs in Nac shell, and blocked the enhanced locomotor response to local microinjection of the D-1 receptor agonist, SKF-82958, in food-restricted, but not ad libitum fed, subjects. Although microinjection of the D-2 receptor agonist, quinpirole, also induced greater locomotor activation in food-restricted than ad libitum fed rats, this effect was not decreased by Naspm. Taken together, the present findings are consistent with synaptic incorporation of CP-AMPARs in D-1 receptor expressing medium spiny neurons in NAc as a mechanistic underpinning of the enhanced responsiveness of food-restricted rats to natural rewards and drugs of abuse

Food restriction (FR) and obesogenic (OB) diets are known to alter brain dopamine transmission and exert opposite modulatory effects on behavioral responsiveness to psychostimulant drugs of abuse. Mechanisms underlying these diet effects are not fully understood. In the present study we examined diet effects on expression and function of the dopamine transporter (DAT) in caudate-putamen (CPu), nucleus accumbens (NAc), and midbrain regions. DA uptake by CPu, NAc or midbrain synapto(neuro)somes was measured in vitro with rotating disk electrode voltammetry or with [3 H]DA uptake and was found to correlate with DA transporter (DAT) surface expression, assessed by maximal [3 H]CFT binding and surface biotinylation assays. FR and OB diets were both found to decrease DAT activity in CPu with a corresponding decrease in surface expression but had no effects in the NAc and midbrain. Diet treatments also affected sensitivity to insulin-induced enhancement of DA uptake, with FR producing an increase in CPu and NAc, likely mediated by an observed increase in insulin receptor (InsR) expression, and OB producing a decrease in NAc. The increased expression of InsR in NAc of FR rats was accompanied by increased DA D2 receptor (D2 R) expression, and the decreased DAT expression and function in CPu of OB rats was accompanied by decreased D2 R expression. These results are discussed as partial mechanistic underpinnings of diet-induced adaptations that contribute to altered behavioral sensitivity to psychostimulants that target the DAT

Structural competency provides a language and theoretical framework to promote institutional-level interventions by clinical practitioners working with community organizations, non-health-sector institutions, and policy makers. The special collection of articles on structural competency in this issue of Academic Medicine addresses the need to move from theory to an appraisal of core educational interventions that operationalize the goals of and foster structural competency. In this Commentary, the authors review the role of clinical practitioners in enhancing population-level health outcomes through collaborations with professionals in fields outside medicine, including the social sciences and law. They describe the core elements of structural competency in preclinical and clinical education, as illustrated by the articles of this special collection: perceiving the structural causes of patients' disease, envisioning structural interventions, and cultivating alliances with non-health-sector agencies that can implement structural interventions. Finally, the authors argue that preparing trainees to form partnerships will empower them to influence the social determinants of their patients' health and reduce health inequalities.

BACKGROUND: Growing evidence of adverse outcomes following synthetic cannabinoid use has engendered interest into populations at risk. The existing literature reports that synthetic cannabinoid use is predominant among young, white males. However, reports from local Departments of Health have found contrary evidence, showing that synthetic cannabinoid use is prevalent in populations other than those of young, white men. OBJECTIVES: This study sought to examine sociodemographic characteristics associated with self-reported synthetic cannabinoid use among a clinical psychiatric population within a public hospital in New York City. METHODS: A cross-sectional medical record review was conducted on synthetic cannabinoid users and non-users in an emergency psychiatric setting. A total of 948 patients who presented at the emergency psychiatric setting in 2014 were included in this sample, 110 (11.6%) of whom were synthetic cannabinoid users. Logistic regressions were used to determine the sociodemographic correlates of synthetic cannabinoid use. RESULTS: The most prominent correlate of synthetic cannabinoid use was homelessness/residing in a shelter during time of treatment (AOR = 17.77, 95% CI = 9.74-32.5). Male (AOR = 5.37, 95% CI = 2.04-14.1), non-white (AOR = 2.74, 95% CI = 1.36-5.54), and younger age (AOR = .961, 95% CI = .940-.980) were also significant correlates of synthetic cannabinoid use. CONCLUSION: Synthetic cannabinoid use among the homeless and mentally ill is a growing public health concern, representing a population with unique clinical and social needs. Areas and populations with high rates of homelessness should be targeted for synthetic cannabinoid prevention and treatment efforts, particularly in urban and racial/ethnic minority communities.

BACKGROUND AND OBJECTIVES: Psychiatry residents provide care for individuals diagnosed with co-occurring mental illness and substance use disorders (SUDs). Small studies have shown that clinicians in general possess negative attitudes towards these dually diagnosed individuals. This is a serious concern, as clinicians' stigmatizing attitudes towards individuals with mental illnesses may have a particularly potent adverse impact on treatment. The goal of this study was to examine the attitudes of psychiatry residents towards individuals with diagnoses of schizophrenia, multiple SUDs, co-occurring schizophrenia and SUDs, and major depressive disorder. METHODS: A questionnaire was sent to psychiatry residents (N = 159) around the country. It was comprised of two sections: (i) demographic information, which included information about level of training; and (ii) the 11-item Medical Condition Regard Scale (MCRS) for individuals with the four different diagnoses. RESULTS: Psychiatry residents had more stigmatizing attitudes towards individuals with diagnoses of SUDs with and without schizophrenia than towards those individuals with diagnoses of schizophrenia or major depressive disorder alone. Senior residents possessed more negative attitudes towards individuals with SUDs than junior residents. DISCUSSION AND CONCLUSIONS: The attitudes of psychiatry residents' towards individuals with SUDs with and without schizophrenia were negative and were worse among senior residents. There were many potential reasons for these findings, including repeat negative experiences in providing care for these individuals. SCIENTIFIC SIGNIFICANCE: The negative attitudes of psychiatry residents towards individuals with SUDs are worrisome. Future work is needed to better understand these attitudes and to develop interventions to improve them. (Am J Addict 2016;XX:1-5).
