OBJECTIVE:To characterize the prevalence of tobacco, alcohol, and drug use and the acceptability of screening in university health centers. PARTICIPANTS/METHODS:Five hundred and two consecutively recruited students presenting for primary care visits in February and August, 2015, in two health centers. METHODS:Participants completed anonymous substance use questionnaires in the waiting area, and had the option of sharing results with their medical provider. We examined screening rates, prevalence, and predictors of sharing results. RESULTS:Past-year use was 31.5% for tobacco, 67.1% for alcohol (>4 drinks/day), 38.6% for illicit drugs, and 9.2% for prescription drugs (nonmedical use). A minority (43.8%) shared screening results. Sharing was lowest among those with moderate-high risk use of tobacco (OR =0.37, 95% CI 0.20-0.69), alcohol (OR =0.48, 95% CI 0.25-0.90), or illicit drugs (OR =0.38, 95% CI 0.20-0.73). CONCLUSIONS:Screening can be integrated into university health services, but students with active substance use may be uncomfortable discussing it with medical providers.

BACKGROUND:Drug use is prevalent among electronic dance music (EDM) party attendees, but research is needed to determine the extent of adverse drug-related outcomes in this population in order to better inform prevention and harm reduction efforts. METHOD/METHODS:1029 adults were surveyed entering EDM parties in New York City in 2018. Those reporting past-year use of a drug were asked if they experienced a harmful or very unpleasant effect after use in which they were concerned about their immediate safety. They were also asked about co-use of other drugs and whether they sought help. RESULTS:We estimate that a third (33.5%) of EDM party attendees have experienced a drug-related adverse effect in the past year. Two-thirds (67.8%) of adverse effects involved use of alcohol. Relative to use, adverse effects most commonly resulted from use of opioids (e.g., prescription opioid misuse, 41.2%) or alcohol (33.9%). Among those reporting an adverse effect, concomitant use of other drugs was common, particularly among users of LSD (56.5%), ketamine (56.3%), cocaine (55.7%), and ecstasy/MDMA/Molly (47.7%). Adverse effects resulting from synthetic cathinone ("bath salt") use were most likely to result in a hospital visit (57.1%). CONCLUSION/CONCLUSIONS:Adverse effects from drug use are common among those in the EDM party scene and polydrug use appears to be a common risk factor. More research is needed, however, to determine the extent of event-specific adverse outcomes. Results can inform prevention and harm reduction efforts in this population.

Runaway and homeless youth (RHY) are dependent on the specialized settings that locate, engage, and serve them. Yet, little research has focused on the features of effective settings for RHY. The present qualitative study, grounded in the Youth Program Quality Assessment model, explored characteristics of higher quality organizations for RHY and gaps that remain from staff and RHY perspectives. A total of 29 diverse settings serving RHY in New York State were randomly selected for participation, and ranked on a quantitative program quality index. Within settings, we conducted in-depth semi-structured interviews with program administrators (N=30) and other staff (N=24). Focus group interviews were conducted with RHY (N=13 focus groups; N=84 RHY). Data were analyzed using a systematic content analysis approach that was both theory-driven and inductive, comparing higher to lower quality settings. We found all settings provided vital services and experienced challenges, but higher quality settings ameliorated challenges through 1) a youth-centered program philosophy equally understood by staff and RHY; 2) developmentally appropriate relationships between staff and RHY that promoted autonomy; 3) a focus on short- and long-term goals within anticipated crises; and 4) ongoing internal quality assessment procedures. Within lower-quality settings we found 1) difficulties retaining effective staff and 2) a primary focus on basic services and managing crises, but less attention to emotional support, exacerbated by 3) funding and other challenges emerging from the larger environment. The present study extends the literature on organizations for RHY by identifying characteristics of higher quality settings, and challenges that remain.

BACKGROUND:The highest rates of new HIV infections are observed in African Americans and Hispanics/Latinos (ethnic minority) adolescents and young adults (youth). HIV-infected ethnic minority youth are less likely to initiate and maintain adherence to antiretroviral treatment (ART) and medical care, as compared with their adult counterparts. OBJECTIVE:The objective of this research protocol was to describe our proposed methods for testing a peer-led mobile health cognitive behavioral intervention, delivered via remote videoconferencing and smartphones with HIV-infected ethnic minority youth, Adherence Connection for Counseling, Education, and Support (ACCESS). Our secondary aim was to obtain initial estimates of the biobehavioral impact of ACCESS on HIV virologic outcomes and self-reported ART adherence, beliefs and knowledge about ART treatment, adherence self-efficacy, and health care utilization (retention in care). METHODS:An exploratory, sequential mixed-methods study design will be used with conceptual determinants of adherence behavior informed by the information-motivation-behavioral skills model. HIV-infected ethnic minority youth aged 16 to 29 years with a detectable HIV serum viral load of more than 200 copies/ml (N=25) will be recruited. Qualitative pretesting will be conducted, including semistructured, in-depth, individual interviews with a convenience sample meeting the study inclusion criteria. Preliminary analysis of qualitative data will be used to inform and tailor the ACCESS intervention. Testing and implementation will include a one-group pre-posttest pilot, delivered by a trained successful peer health coach who lives with HIV and is well-engaged in HIV care and taking ART. A total of 5 peer-led remote videoconferencing sessions will be delivered using study-funded smartphones and targeting adherence information (HIV knowledge), motivation (beliefs and perceptions), and behavioral skills (self-efficacy). Participant satisfaction will be assessed with poststudy focus groups and quantitative survey methodology. Bivariate analyses will be computed to compare pre- and postintervention changes in HIV biomarkers, self-reported ART adherence, beliefs and knowledge about ART, adherence self-efficacy, and retention in care. RESULTS:As of December 2018, we are in the data analysis phase of this pilot and anticipate completion with dissemination of final study findings by spring/summer 2019. The major outcomes will include intervention feasibility, acceptability, and preliminary evidence of impact on serum HIV RNA quantitative viral load (primary adherence outcome variable). Self-reported ART adherence and retention in care will be assessed as secondary outcomes. Findings from the qualitative pretesting will contribute to an improved understanding of adherence behavior. CONCLUSIONS:Should the ACCESS intervention prove feasible and acceptable, this research protocol will contribute to a shift in existent HIV research paradigms by offering a blueprint for technology-enabled peer-led interventions and models.

BACKGROUND:Electronic dance music (EDM) parties at nightclubs and festivals are high-risk scenes for drug use. Although intention to use drugs (such as ecstasy) has been shown to be the most proximal determinant of use, little is known regarding the extent to which drug use is unplanned in this high-risk scene. METHODS:We surveyed 954 adults entering EDM parties in New York City in 2017 and asked about planned drug use that night. A quarter (n = 236) completed the optional online follow-up survey which asked about drug use during their outing. We examined prevalence and correlates of planned and unplanned use. RESULTS:A fifth (21.0%) of attendees reported planning to use a specific drug the night of the party and over a third (35.4%) reported using a drug later that night. A quarter (26.6%) used in an unplanned manner. Unplanned marijuana use was most common (10.7%), followed by unplanned use of ecstasy (7.3%), cocaine (4.7%), amphetamine (1.4%), LSD (1.3%), and MDA (1.1%). Unplanned initiation of ecstasy and PMA also occurred. Unplanned drug use was more likely to occur among those recruited outside of nightclubs compared to festivals. Non-heterosexual participants and those with a college degree or higher were also more likely to engage in unplanned marijuana use compared to heterosexual and less educated participants, respectively. CONCLUSIONS:Unplanned drug use is common at EDM parties. Results can inform prevention and harm reduction in these scenes as unplanned use may exacerbate potential adverse outcomes related to drug use and often extreme party environments.

BACKGROUND/OBJECTIVE/OBJECTIVE:Racial/ethnic disparities in type 2 diabetes (T2D) outcomes exist, and could be explained by nutrition- and inflammation-related differences. The objective of this study is to identify associations between race/ethnicity and glucose control among participants from NHANES 2007-2010, as influenced by diet quality, body mass, and inflammation and grouped by T2D status. SUBJECTS/METHODS/METHODS:The following is a cross-sectional, secondary data analysis of two NHANES data cycles spanning 2007-2010. The association between race/ethnicity and hemoglobin A1c (HbA1c) as mediated by dietary intake score, body mass index (BMI), and C-reactive protein (CRP) was assessed, as was the strength of the difference of that association, or moderation, by T2D status. The sample included n = 7850 non-pregnant adult participants ≥ 20 years of age who had two days of reliable dietary recall data, and no missing data on key variables included in the analysis. The primary outcome examined was HbA1c. RESULTS:The model accurately explained the variation in HbA1c measures in participants without T2D, as mediated by diet quality, BMI, and CRP. However, significant variation in HbA1c remained after accounting for aforementioned mediators when contrasting non-Hispanic White to non-Hispanic Black participants without T2D. The model was not a good fit for explaining racial/ethnic disparities in HbA1c in participants with T2D. A test of the index of moderated mediation for this model was not significant for the differences in the effect of race/ethnicity on HbA1c by T2D status (moderator). CONCLUSIONS:This study demonstrated that diet quality, BMI, and CRP mediated the effect of race/ethnicity on HbA1c in persons without T2D, but not in persons with T2D. Further research should include additional inflammatory markers, and other inflammation- and T2D-related health outcomes, and their association with racial/ethnic disparities in diabetes.

BACKGROUND:Our previous research has found low and stable mean drug treatment coverage among people who inject drugs (PWID) across 90 large US metropolitan statistical areas (MSAs) during 1993-2002. This manuscript updates previous estimates of change in drug treatment coverage for PWID in 90 MSAs during 1993-2007. METHODS:Our drug treatment sample for calculating treatment coverage includes clients enrolled in residential or ambulatory inpatient/outpatient care, detoxification services, and methadone maintenance therapy at publicly- and privately-funded substance abuse agencies receiving public funds. Coverage was measured as the number of PWID in drug treatment, calculated by using data from the Substance Abuse and Mental Health Service Administration, divided by numbers of PWID in each MSA. We modeled change in drug treatment coverage rates using a negative binomial mixed-effects model. Fixed-effects included an intercept and a main effect for time. Incidence rate ratios (IRR) were calculated for both average change from 1993 to 2007 and MSA-specific estimates of change in coverage rates. RESULTS:On average over all MSAs, coverage was low in 1993 (6.1%) and showed no improvement from 1993 to 2007 (IRR = 0.99; 95% CI, 0.86, 1.2). There was modest variability across MSAs in coverage in 1993 (log incidence rate SD = 0.36) as well as in coverage change from 1993 to 2007 (log IRR SD = 0.32). In addition, results indicate significant variability among MSAs in coverage. CONCLUSIONS:Inadequate treatment coverage for PWID may produce a high cost to society in terms of the spread of overdose mortality and injection-related infectious diseases. A greater investment in treatment will likely be needed to have a substantial and more consistent impact on injection drug use-related harms. Future research should examine MSA-level predictors associated with variability in drug treatment coverage.

PURPOSE:To explore factors that influence the success of adult strabismus surgery based on health-related quality of life (HRQOL) criteria. METHODS:The HRQOL aspect of strabismus surgery was assessed using the Adult Strabismus 20 (AS-20) questionnaire. Adult patients (≥16 years of age) undergoing strabismus surgery between 2014 and 2016 were identified using a treatment register. Pre- and postoperative AS-20 scores were calculated. HRQOL surgical success was defined as a pre- to postoperative change in AS-20 score exceeding previously published 95% limits of agreement. Any relationship between demographic factors (sex, age, and socioeconomic status), presence or absence of diplopia, type and magnitude of deviation, and change in deviation size with HRQOL success was investigated. RESULTS:A total of 87 patients were included (mean age, 47 years; 53% female). Nondiplopic patients showed significantly lower pre- and postoperative scores on the AS-20 psychosocial subscale compared to diplopic patients. Of 87 surgeries, 54 (62%) were classified as successful based on HRQOL criteria. Multiple logistic regression analysis showed only lower socioeconomic status to be significantly associated with a higher rate of HRQOL success (P = 0.04). CONCLUSIONS:Strabismic patients with a lower socioeconomic status are more likely to achieve HRQOL success following surgery. We also show that nondiplopic patients have more psychosocial concerns than those with diplopia and that this disparity persists even after strabismus surgery.
