Proactive Psychiatry: Innovating the Delivery of Consultation-Liaison Services in a Pediatric Hospital.

BACKGROUND: The benefits of a proactive consultation-liaison (C-L) psychiatry service have been well-documented in the adult population, including decreased length of stay, increased satisfaction among physicians, and enhanced collaborative care. However, there is no available research on the effectiveness of this model in pediatric hospitals. OBJECTIVE: This study compared patients ages 5-18 years on a general medical floor receiving a proactive psychiatry consult to concurrent controls receiving no consult and to historical controls receiving traditional reactive consults. METHOD: New admissions to two pediatric general medical hospital teams were reviewed on weekday mornings to identify those with active psychiatric concerns. Adjusted negative binomial regression was used to compare the primary outcome of hospital length of stay between the proactive (n=65), concurrent control (n=63), and reactive historical control (n=45) groups. Patient satisfaction, hospitalist satisfaction, and recommendation concordance (degree to which psychiatry recommendations were implemented by the primary team) were also compared between groups as secondary outcome measures. RESULTS: After adjusting for age, sex, race, insurance type, reason for consult, and medical diagnosis, concurrent control patients had 14% (p = 0.295) longer mean length of stay than proactive consults and historical controls had twice (p < 0.001) the mean length of stay of those with proactive consults. Response rate for patient satisfaction scores was low, but responses were modestly more favorable among patients who received proactive C-L services. Based on nine paired pediatric hospitalist pre- and post- surveys, follow-up surveys were statistically significantly more favorable after a proactive psychiatry consult service was introduced. Concordance of recommendations was observed to be higher for proactive consults than concurrent controls for diagnoses and non-medication (other) recommendations. CONCLUSION: The positive impact of a proactive C-L psychiatry consultation model was observed in a pediatric hospital and was associated with a lower length of stay than concurrent controls and historical reactive consults, higher hospitalist satisfaction among paired responses, and greater concordance of diagnosis and other non-medication recommendations.

Relationship Between Obesity and Intellectual/Developmental Disability in an Ohio Telepsychiatry Clinic: A Retrospective Review.

Co-occurring intellectual/developmental disability (IDD) and overweight/obesity (OW/OB) is an important consideration of IDD psychiatric care. The relationship between OW/OB and comorbid diagnoses of Autism Spectrum Disorder (ASD) and/or IDD remains inadequately described in existing literature. The purpose of this study is to explore these co-occurring diagnoses. Improved understanding of associated comorbidities can guide clinicians toward interventions to minimize complications associated with OW/OB. We conducted a retrospective review of adult patients of a telepsychiatry clinic with IDD or ASD defined by DSM-5. ICD-10 diagnosis of IDD or ASD, demographics, BMI, comorbidities, and current medications were recorded. Binary logistic regression was used to estimate associations between each predictor and the outcomes overweight (body mass index (BMI) ≥ 25 kg/m2) and obesity (BMI ≥ 30 kg/m2). Prevalence of obesity in these 412 adults was 52.4% (95% CI 47.5, 57.3). There was a significant inverse relationship between IDD severity and the odds of each outcome (p < .001). 80.3% of patients were being actively treated with an antidepressant. Patients taking an antidepressant had twice the odds of obesity (adjusted OR 2.03, 95% CI 1.23, 3.41, p = .006). These findings provide a sense of urgency for prevention of OW/OB and its associated medical sequelae. Prevalence of obesity was higher in this sample compared to the general population. The inverse relationship between IDD severity and OW/OB warrants further research examining age, caregiver involvement, and access to care as potential modifiers.

Climate Change and Mental Health: An Interactive Educational Session.

Introduction: Climate change is the single biggest health threat facing humanity, with direct and indirect impacts on mental health, yet health impacts of climate change remain notably absent from most medical school curricula. We describe a timely interactive educational session on climate change and mental health that was implemented and studied on a medical student clinical psychiatry rotation. Methods: We developed a 1-hour introductory session on the mental health impacts of climate change and potential solutions. The session was delivered to third-year medical students on their 4-week clinical psychiatry rotation and included pre- and postsession survey questions assessing their knowledge, comfort, and readiness regarding the topic. Results: Seventy students participated in the session, with 49 students completing the pre- and postsession surveys, giving a response rate of 70%. The average score for the four Likert-scale questions on the survey increased from 2.7 presession to 3.9 postsession on a 5-point scale (1 = strongly disagree, 5 = strongly agree). All questions displayed statistically significant improvement. Qualitative analysis identified knowledge gained about the mental health impacts of climate change as the most important aspect of the session to students. Discussion: The introductory session effectively filled an urgent need in medical education curricula regarding climate change's effects on human health. Overall, distribution of and improvement upon this timely teaching content can serve a valuable role in medical student education as the effects of climate change, particularly on mental health, continue to progress throughout the century.

An Evaluation of Messages to Promote Parental Intent to Vaccinate Children Aged <12 Years Against COVID-19.

OBJECTIVES: Effective health communication can increase intent to vaccinate. We compared 8 messages that may influence parents' intent to vaccinate their children against COVID-19. METHODS: In a cross-sectional survey of adults in the United States administered online in August 2021, 1837 parents and legal guardians were exposed to 8 messages (individual choice, gain/practical benefits, nonexpert, health care provider recommendation, altruism/community good, safety/effectiveness, safety, and effectiveness) to determine message reception and influence on intent to vaccinate their children. Parents responded to 10 questions using a Likert scale. We computed odds ratios (ORs) for each message, with an OR >1.0 indicating greater observed odds of participant agreement with the follow-up statement as compared with a reference message. We compared outcomes individually across messages with ordinal logistic regression fit using generalized estimating equations. RESULTS: The individual choice message had the highest odds of agreement for understanding intent (OR = 2.10; 95% CI, 1.94-2.27), followed by the health care provider recommendation message (OR = 1.58; 95% CI, 1.46-1.71). The individual choice message had the highest odds of memorability, relatability, and trustworthiness. The altruism/community good message was at or near second best. The altruism/community good message had the highest or near-highest odds of increasing parents' intent to vaccinate their children, asking friends and family for their thoughts, and searching for additional information. The message that most motivated parents to vaccinate their children depended on parental intent to vaccinate prior to being exposed to the tested messages. CONCLUSIONS: Messages with themes of individual choice, health care provider recommendation, and altruism/community good may be used in future message campaigns. Further research is needed to refine message concepts related to altruism/community good.

Depression as a mediator of the association between vision and/or hearing loss and recent substance use: NHANES 2013-2018.

BACKGROUND: Previous research has demonstrated a significant association between vision and/or hearing loss and lifetime substance use. OBJECTIVE: The objective of this analysis was to assess whether depression mediates the association between vision and/or hearing loss and recent substance use (RSU). METHODS: Data from 9408 NHANES 2013-2018 participants were used for a survey-weighted analysis to assess whether the indirect effect (IE) of disability status (neither, vision loss only, hearing loss only, both) on the outcome RSU (past 30-day use of marijuana, cocaine, methamphetamine, or heroin) was mediated by recent (past 2 weeks) depression (Patient Health Questionnaire- 9 items score; none = 0-4, mild or greater = 5+), adjusting for confounders. RESULTS: The estimated prevalence of vision and/or hearing loss, mild or greater depression, and RSU were 6.7 %, 24.1 %, and 16.8 %. RSU was significantly positively associated with disability status before (p = .018) but not after adjusting for depression (p = .160), and the indirect effects were statistically significant (p < .001). CONCLUSIONS: The data are consistent with the hypothesis that recent depression mediates the association between vision and/or hearing loss and RSU. Initiatives may be needed that incorporate a focus on the prevention, management, or care for depression to intervene on the pathway between hearing and/or vision loss and RSU.

Trajectories of non-prescribed buprenorphine and other opioid use: A multi-trajectory latent class growth analysis.

INTRODUCTION: With the increasing use of non-prescribed buprenorphine (NPB), we need more data to identify the longitudinal patterns of NPB use. The goal of this natural history study is to characterize heterogeneity in trajectories of NPB, other opioid use, and participation in medication for opioid disorder (MOUD) treatment among a community-recruited sample of individuals with current opioid use disorder (OUD). METHODS: The study recruited a community-based sample of 357 individuals with OUD who used NPB in the past 6 months in Ohio, United States, for baseline and follow-up assessments (every 6 months for 2 years) of drug use, treatment participation, and other health and psychosocial characteristics. The study used multiple imputation to handle missing data. We used a multi-trajectory latent class growth analysis (MT-LCGA) to find salient groupings of participants based on the trajectories of NPB, other opioid use, and treatment participation. RESULTS: Over time, NPB use frequency declined from a mean of 14.6 % of days at baseline to 3.6 % of days at 24-month follow-up along with declines in heroin/fentanyl (56.4 % to 23.6 % of days) and non-prescribed pharmaceutical opioid (NPPO) use (11.6 % to 1.5 % of days). Participation in MOUD treatment increased from a mean of 17.0 % of days at baseline to 52.4 % of days at 24 months. MT-LCGA identified a 6-class model. All six classes showed declines in NPB use. Class 1 (28 %) was characterized by high and increasing MOUD treatment utilization. Class 2 (21 %) showed sustained high levels of heroin/fentanyl use and had the lowest levels of NPB use (2.2 % of days) at baseline. Class 3 (3 %) was characterized as the primary NPPO use group. Class 4 (5 %) transitioned from high levels of NPB use to increased MOUD treatment utilization. It had the highest levels of NPB use at baseline (average of 80.7 % of days) that decreased to an average of 12.9 % of days at 24 months. Class 5 (16 %) showed transition from high levels of heroin/fentanyl use to increased MOUD treatment utilization. Class 6 (27 %) showed decreased heroin/fentanyl use over time and low MOUD treatment utilization. Classes showed varying levels of improvement in psychosocial functioning, polydrug use, and overdose risks. CONCLUSION: Overall, our findings suggest that NPB use was generally self-limiting with individuals reducing their use over time as some engage in greater utilization of MOUD treatment. A need exists for continuing improvements in MOUD treatment access and retention.

Vision and hearing loss associated with lifetime drug use: NHANES 2013-2018.

BACKGROUND: One in four American adults has a disability. Individuals with disabilities are more likely to have mental health issues and use substances and are less likely to attend substance use rehabilitation compared to individuals without disabilities. However, most research about substance use and substance use rehabilitation does not focus specifically on sensory disabilities. OBJECTIVE: The purpose was to test the association between vision and/or hearing loss, lifetime drug use, and lifetime drug rehabilitation. METHODS: Data files from National Health and Nutrition Examination Survey cycles (2013-2014, 2015-2016, 2017-2018) were combined. Ordinal logistic regression was used to test the association between vision and hearing loss and lifetime drug use and binary logistic regression to test the association with lifetime rehabilitation among those who had used drugs, adjusting for multiple testing and the complex survey design. RESULTS: There was a significant association between vision and hearing loss status and lifetime drug use (p = .018), but not with lifetime rehabilitation (p = .972). Post-hoc comparisons were not statistically significant. However, individuals with vision loss only and hearing loss only had 36% and 37% greater odds, respectively, of drug use than those without a disability, and those with both vision and hearing loss had 18% greater odds of drug use than those with either alone. CONCLUSIONS: Persons with disability were more likely to have used drugs but were not more likely to have gone to drug rehabilitation.

Perfluoroalkyl Substances and Abdominal Aortic Calcification.

OBJECTIVE: To evaluate if serum perfluoroalkylated substances (PFAS) were associated with abdominal aortic calcification (AAC). METHODS: We used weighted logistic regression to investigate the gender-specific association between PFAS serum levels and AAC more than or equal to 6 from dual-energy X-ray absorptiometry (DXA) scans of the thoraco-lumbar spine from National Health and Nutrition Examination Survey 2013-2014 survey participants aged more than or equal to 40 years. RESULTS: After adjusting for confounding, none of log-transformed perfluorooctanoic acid (PFOA), perfluorooctane sulfonate (PFOS), perfluorohexane sulfonic acid (PFHxS), or perfluorononanoic acid (PFNA) were significantly associated with AAC for either men or women (adjusted odds ratios [ORs] ranged from 0.80 to 1.33, P  > 0.05 each). For PFOA and PFOS, the association was positive only in women (although the difference was not statistically significant in either case). CONCLUSION: These findings do not provide general support for a relationship of PFAS exposure to AAC, although the results show a need for gender-specific consideration in a larger dataset.

Exploring the Interactions between Non-Medical Methamphetamine Use and Prescribed Buprenorphine or Naltrexone in Opioid Use Disorder Treatment Retention.

OBJECTIVES: Our objectives were to examine the impact of methamphetamine use on opioid use disorder (OUD) treatment retention in patients prescribed either buprenorphine/buprenorphine-naloxone (BUP-NX) or naltrexone/extended-release naltrexone (XR-NTX), while also exploring the role of other risk factors that may modify the impact of methamphetamine use. METHODS: We conducted an exploratory retrospective study examining OUD treatment retention in 127 patients in Ohio (USA). Patients were prescribed either BUP-NX or naltrexone/XR-NTX. Cox proportional hazard regression was used to compare time to dropout of treatment between patients positive and negative on screening for methamphetamines at intake, estimate the association between other risk factors and time to dropout, and test interactions between risk factors and methamphetamine status. RESULTS: Among patients prescribed naltrexone/XR-NTX, those positive for methamphetamines had almost three times the risk of treatment dropout (AHR = 2.89, 95% CI =1.11, 7.07), significantly greater (interaction p = .039) than the methamphetamine effect among those prescribed BUP-NX (AHR = 0.94, 95% CI = 0.51, 1.65). Early in treatment, being prescribed BUP-NX was strongly associated with a greater risk of treatment dropout (at baseline: AHR = 2.90, 95% CI = 1.33, 7.15), regardless of baseline methamphetamine use status. However, this effect decreased with time and shifted to greater risk of dropout among those prescribed naltrexone/XR-NTX (non-proportional hazard; interaction with time AHR = 0.66, 95% CI = 0.49, 0.86), with the shift occurring sooner among those positive for methamphetamine at baseline. CONCLUSIONS: Additional support should be provided to patients who use methamphetamines prior to starting OUD treatment.

Association Between Proportion of Workday Treating COVID-19 and Depression, Anxiety, and PTSD Outcomes in US Physicians.

OBJECTIVE: The primary objective of this cross-sectional study was to examine the association between time spent treating patients with Coronavirus disease 2019 (COVID-19) and levels of depression, anxiety, and posttraumatic stress disorder (PTSD) in US physicians. METHODS: The authors conducted an anonymous online survey of US physicians. Linear regression was used to test the association between proportion of day treating COVID-19 and symptoms of depression, anxiety, and PTSD. RESULTS: In a sample of 1724 US physicians, proportion of day treating COVID-19 was positively and significantly associated with depression, anxiety, and PTSD scores (P < 0.001 for each). CONCLUSIONS: Mental health resources should be provided to physicians who treat COVID-19 because the proportion of day treating COVID-19 is associated with depression, anxiety, and PTSD outcomes.

Unintentional drug overdose: Is more frequent use of non-prescribed buprenorphine associated with lower risk of overdose?

BACKGROUND: Unintentional drug overdoses have reached epidemic levels in the U.S. This study tests the hypothesis that people who have used non-prescribed buprenorphine more frequently in the past six months were less likely to experience a drug overdose during that same time period. METHODS: Participants age 18 years or older with opioid use disorder who reported use of non-prescribed buprenorphine in the last six months were recruited from the Dayton, Ohio, area using a combination of targeted and modified respondent-driven sampling. Participants completed a structured interview, including six-month timeline follow-back, after informed consent. Logistic regression was used to test the association between (log-transformed) frequency of non-prescribed buprenorphine use and overdose in the previous six months, adjusted for confounding due to sex, homelessness, incarceration, substance use treatment, previous overdose, heroin/fentanyl injection, psychiatric comorbidity, and (log-transformed) frequencies of other (non-opioid) drug use. RESULTS: Almost 89% of 356 participants were white, 50.3% were male, and 78.1% had high school or greater education. Over 27% (n = 98) reported experiencing an overdose in the past six months. After adjusting for confounding, greater frequency of non-prescribed buprenorphine use was significantly associated with lower risk of overdose (AOR = 0.81, 95% CI = 0.66, 0.98; p = .0286). Experiencing an overdose more than six months ago (AOR = 2.19, 95% CI = 1.24, 3.97); injection as the most common route of administration of heroin/fentanyl (AOR = 2.49, 95% CI = 1.36, 4.71); and frequency of methamphetamine use (AOR = 1.13, 95% CI = 1.02, 1.27) were strongly associated with increased risk of recent overdose in multivariable analysis. DISCUSSION: The findings support our hypothesis that higher frequency of non-prescribed buprenorphine use is associated with lower risk of drug overdose, a potential harm reduction consequence of diversion. Improving the availability of buprenorphine though standard substance use disorder treatment, primary care, and other innovative methods is urgently needed.

Patterns of non-prescribed buprenorphine and other opioid use among individuals with opioid use disorder: A latent class analysis.

AIM: Non-prescribed buprenorphine (NPB) use increased in the US. This study aims to characterize heterogeneity in patterns of NPB and other opioid use among individuals with current opioid use disorder. METHODS: The study recruited 356 participants in Dayton (Montgomery County), Ohio, area in 2017-2018 using targeted and Respondent Driven Sampling. Participants met the following criteria: 1) 18 years or older, 2) current moderate/severe opioid use disorder (DSM-5), 3) past 6-month NPB use. Latent class analysis (LCA) was conducted to identify subgroups based on past 6-month (days of NPB and heroin/fentanyl use; use of NPB to get high; use of non-prescribed and prescribed pharmaceutical opioids; participation in formal treatment) and lifetime (years since first NPB and other illicit opioid use) characteristics. Selected auxiliary variables were compared across classes using Asparouhov and Muthén's 3-step approach. RESULTS: 49.7% were female, and 88.8% were non-Hispanic whites. 89% used NPB to self-treat withdrawal. LCA resulted in three classes: "Heavy Heroin/Fentanyl Use" (61%), "More Formal Treatment Use" (29%) and "Intense NPB Use" (10%). After adjusting for multiple testing, the following past 6-month variables differed significantly between classes: injection as a primary route of heroin/fentanyl administration (p < 0.001), cocaine use (p = 0.044), unintentional drug overdose (p = 0.023), and homelessness (p = 0.044), with the "Intense NPB Use" class having the lowest prevalences. CONCLUSION: Predominance of self-treatment goals and the association between more intense NPB use and lower risks of adverse consequences suggest potential harm minimization benefits of NPB use. More research is needed to understand consequences of NPB use over time.

Characteristics Associated with Depression and Suicidal Thoughts Among Medical Residents: Results from the DEPRESS-Ohio Study.

OBJECTIVE: This study describes the characteristics that are associated with depression in residents and also examines resident perception of available mental health support. METHODS: Residents and their program directors from each of 10 specialties across all academic training institutions in Ohio were electronically surveyed over a 2-month period. Generalized logistic regression was used to test for association between risk factors and depression and, among depressed residents, with suicidal thoughts. RESULTS: Using the PHQ-9, 19% of residents met criteria for at least moderate depression and 31.1% of depressed residents had suicidal thoughts. Over 70% of depressed residents were not receiving treatment, including 70% of depressed residents with suicidal thoughts. Residents who were unaware of wellness programming or did not believe their program director would be supportive of a depressed resident were significantly more likely to be depressed. Residents who believed depression treatment would negatively impact medical licensure were significantly more likely to be depressed. Male program directors and those in their position for fewer than 5 years were significantly more likely to have depressed residents in their program. CONCLUSIONS: A substantial proportion of depressed residents have suicidal thoughts, and most are not receiving treatment. Depressed residents may perceive the availability of support from their program director differently than their non-depressed colleagues, and may perceive greater risk to medical licensure if they seek treatment.

Perceptions of Residents and Their Training Directors Regarding Wellness Education, Program Support, and Access to Depression Treatment: the DEPRESS-Ohio Study.

OBJECTIVE: This study determines the extent to which residents and their program directors have discordant perceptions regarding wellness, support, and treatment opportunities for trainees. In addition, the authors examined whether psychiatry residents differed in their perceptions compared with residents in other specialties. METHODS: Residents and their program directors from each of 10 specialties were electronically surveyed after IRB approval and giving informed consent. RESULTS: Of 42 program directors responding, over 92% indicated they provided wellness education and programming; however, a significantly lower percentage of 822 trainees were aware of this (81.2% and 74.9%, respectively). A similar disparity existed between program directors (PDs) who knew where to refer depressed residents for help (92.9%) and residents who knew where to seek help (71%). Moreover, 83.3% of program directors believed they could comfortably discuss depression with a depressed resident, but a lower percentage of their trainees (69.1%) felt their training directors would be supportive. A significantly greater percentage of program directors (40.5%) believed seeking treatment for depression might compromise medical licensure than did residents (13.0%). Psychiatry residents were significantly more aware of wellness, support, and access than were residents from other specialties. CONCLUSIONS: The availability of wellness education, programming, program director accessibility, and knowing where to ask for help if depressed does not seem to be adequately communicated to many residents. Moreover, program directors disproportionately see depression treatment as a risk to medical licensure compared with their residents. Psychiatry residents seem to be more aware of program director support and access to care than their colleagues.

Trends in fentanyl and fentanyl analogue-related overdose deaths - Montgomery County, Ohio, 2015-2017.

INTRODUCTION: There is a lack of information on illicitly manufactured fentanyl and fentanyl analogue-related (IMF) unintentional overdose death trends over time. The study analyzes IMF-related unintentional overdose fatalities that occurred between July 2015 and June 2017 in Montgomery County, Ohio, an area with the highest rates of unintentional overdose mortality in Ohio. METHODS: LC-MS/MS-based method was used to identify fentanyl analogs and metabolites in 724 unintentional overdose death cases. The Chi-square statistic was used to assess differences over time in demographic and drug-related characteristics. RESULTS: The number of unintentional overdose death cases testing positive for IMFs increased by 377% between second half of 2015 and first half of 2017. The majority of decedents were white (82.5%) and male (67.8%). The proportion of fentanyl-only (no other analogs) cases declined from 89.2%-24.6% (p < 0.001), while proportion of fentanyl analogue-containing cases increased from 9.8%-70.3% (p < 0.001) between the second half of 2015 and first half of 2017. The most commonly identified fentanyl analogs were carfentanil (29.7%), furanyl fentanyl (14.1%) and acryl fentanyl (10.2%). Proportion of IMF cases also testing positive for heroin declined from 21.6% to 5.4% (p < 0.001), while methamphetamine positive cases increased from 1.4%-17.8% (p < 0.001) over the same time period. DISCUSSION: Emergence of fentanyl analogs contributed to substantial increases in unintentional overdose deaths. The data indicate a growing overlap between the IMF and methamphetamine outbreaks. Continuous monitoring of local IMF trends and rapid information dissemination to active users are needed to reduce the risks associated with IMF use.

Are Gender Differences in DSM-5 PTSD Symptomatology Explained by Sexual Trauma?

Although many studies have assessed gender differences in posttraumatic stress disorder (PTSD) prevalence, few examine individual PTSD symptoms (PTSSs). Hypothesizing that trauma differences explain many gender differences in symptomatology, this is the first known study to adjust PTSSs for trauma type, and to compare gender differences in those with sexual traumas. Using a cross-sectional survey methodology in a sample of adult outpatients (n = 775), we examined gender, trauma type, PTSSs, suicide, alcohol, and tobacco. Among those with trauma (n = 483), women generally had more severe symptoms than men, but after adjusting for trauma type, only physical reactivity (p = .0002), excessive startle (p = .0005), external avoidance (p = .0007), internal avoidance (p = .0008), psychological reactivity (p = .0009), and suicide attempts (p = .001) remained significantly worse among women, whereas men more commonly reported alcohol problems (p = .007). Among those with PTSD (n = 164), there were no significant PTSS gender differences. Those with sexual trauma had worse symptoms (particularly amnesia) compared with non-sexual trauma (p < .0001 for PTSD diagnosis and total severity), including within each gender. Among those with sexual trauma (n = 157), men had worse recklessness (p = .004) and more commonly reported tobacco (p = .02), whereas women more commonly attempted suicide (p = .02) and had worse avoidance (p = .04). However, when isolating the effects of sexual trauma beyond other traumas, there were no significant symptom difference-in-differences between genders. Our findings suggest that, while women have higher PTSD rates, men with PTSD present similarly. In addition, while women have higher sexual trauma rates, men may have similarly severe responses. Most gender differences in PTSD presentation appear to be explained by trauma type, particularly women having higher rates of sexual trauma. We discuss potential biopsychosocial explanations.

Global trends, local harms: availability of fentanyl-type drugs on the dark web and accidental overdoses in Ohio.

As America's opioid crisis has become an "epidemic of epidemics," Ohio has been identified as one of the high burden states regarding fentanyl-related overdose mortality. This study aims to examine changes in the availability of fentanyl, fentanyl analogs, and other non-pharmaceutical opioids on cryptomarkets and assess relationship with the trends in unintentional overdoses in Ohio to provide timely information for epidemiologic surveillance. Cryptomarket data were collected at two distinct periods of time: (1) Agora data covered June 2014-September 2015 and were obtained from Grams archive; (2) Dream Market data from March-April 2018 were extracted using a dedicated crawler. A Named Entity Recognition algorithm was developed to identify and categorize the type of fentanyl and other synthetic opioids advertised on cryptomarkets. Time-lagged correlations were used to assess the relationship between the fentanyl, fentanyl analog and other synthetic opioid-related ads from cryptomarkets and overdose data from the Cincinnati Fire Department Emergency Responses and Montgomery County Coroner's Office. Analysis from the cryptomarket data reveals increases in fentanyl-like drugs and changes in the types of fentanyl analogues and other synthetic opioids advertised in 2015 and 2018 with potent substances like carfentanil available during the second period. The time-lagged correlation was the largest when comparing Agora data to Cincinnati Emergency Responses 1 month later 0.84 (95% CI 0.45, 0.96). The time-lagged correlation between Agora data and Montgomery County drug overdoses was the largest when comparing synthetic opioid-related Agora ads to Montgomery County overdose deaths 7 months later 0.78 (95% CI 0.47, 0.92). Further investigations are required to establish the relationship between cryptomarket availability and unintentional overdose trends related to specific fentanyl analogs and/or other illicit synthetic opioids.

PTSD Symptom Severity, but Not Trauma Type, Predicts Mental Health Help-seeking in the Military.

OBJECTIVE: Although veterans with posttraumatic stress disorder (PTSD) have been reported to have high rates of inadequate treatment, to our knowledge this is the first study to evaluate associations between each individual PTSD symptom and treatment-seeking, and the first PTSD help-seeking study to evaluate variables across all-rather than specific-types of trauma. METHODS: This case-control study surveyed a consecutive sample of active duty military outpatients with trauma histories (N=211), comparing those attending voluntary mental health services (help-seeking cases, n=128) or mandatory dental services required for all active duty personnel (general military population controls, n=83). We used logistic regression to estimate associations between help-seeking and demographics, PTSD symptoms, trauma type, suicide attempts, substance use problems, and chronic pain, with each variable adjusted for sex, age, and race. RESULTS: Significant associations were found between help-seeking and PTSD diagnosis (adjusted odds ratio=4.15, P<0.001) and between help-seeking and severities of PTSD symptoms (total, clusters, all individual symptoms except recklessness; each adjusted odds ratio>1, P<0.05). CONCLUSIONS: In this clinical sample, a clear positive relationship was found between help-seeking and PTSD symptom severity, but not with trauma type, suicide attempts, substance use problems, or pain, after adjusting for multiple testing. Possible explanations and implications of these findings are discussed.

A Twitter-based survey on marijuana concentrate use.

AIMS: The purpose of this paper is to analyze characteristics of marijuana concentrate users, describe patterns and reasons of use, and identify factors associated with daily use of concentrates among U.S.-based cannabis users recruited via a Twitter-based online survey. METHODS: An anonymous Web-based survey was conducted in June 2017 with 687 U.S.-based cannabis users recruited via Twitter-based ads. The survey included questions about state of residence, socio-demographic characteristics, and cannabis use including marijuana concentrates. Multiple logistic regression analyses were conducted to identify characteristics associated with lifetime and daily use of marijuana concentrates. RESULTS: Almost 60% of respondents were male, 86% were white, and the mean age was 43.0 years. About 48% reported marijuana concentrate use. After adjusting for multiple testing, significant predictors of concentrate use included: living in "recreational" (AOR = 2.04; adj. p = .042) or "medical, less restrictive" (AOR = 1.74; adj. p = .030) states, being younger (AOR = 0.97, adj. p = .008), and daily herbal cannabis use (AOR = 2.57, adj. p = .008). Out of 329 marijuana concentrate users, about 13% (n = 44) reported daily/near daily use. Significant predictors of daily concentrate use included: living in recreational states (AOR = 3.59, adj. p = .020) and using concentrates for therapeutic purposes (AOR = 4.34, adj. p = .020). CONCLUSIONS: Living in states with more liberal marijuana policies is associated with greater likelihood of marijuana concentrate use and with more frequent use. Characteristics of daily users, in particular, patterns of therapeutic use warrant further research with community-recruited samples.
