rategies to improve uptake of and adherence to relapse prevention medication in this population.
None of the condition x time interactions in the intention-to-treat analyses reached significance. Participants' nonadherence may have contributed to the failure to reject the null hypothesis. Irrespective of randomized condition, participants who received XR-NTX for OUD demonstrated low retention in treatment, receiving an average of only 1.3 subsequent injections, yet reported less opioid use at follow-up than participants who did not received XR-NTX. Treatment programs should consider XR-NTX as a treatment option for youth motivated to receive it. Future research should focus on building developmentally informed strategies to improve uptake of and adherence to relapse prevention medication in this population.Collegiate Recovery Communities (CRCs) are important sources of support for college students building and maintaining recovery from substance use disorders. The current study used daily diary data from members of a CRC to examine with which sources of social support students engaged daily, and whether students connected with these sources more on days when they indicated higher-than-usual recovery difficulty, negative affect, and/or school stress. Results indicate that on days when students reported having greater difficulty with recovery maintenance than usual, they had higher odds of being in contact with family members and were expected to talk or spend time with family for longer than usual. Students also had higher odds of having recovery-focused conversations with both 12-step sponsors and CRC peers on days of greater-than-usual recovery maintenance difficulty. Recovery maintenance difficulty was uniquely associated with longer duration of family contact, above and beyond negative affect and school stress. Poziotinib concentration Thus, the occurrence, amount, and nature of CRC members' interactions with important social network members varied in relation to perceived recovery challenges that same day. Findings highlight the importance of providing college students with multiple sources of support that they can use to maintain their recoveries despite daily challenges.
Buprenorphine, a partial mu-opioid agonist and kappa-opioid antagonist, is an approved treatment for opioid use disorder (OUD). Studies demonstrate that buprenorphine decreases cravings for other opioids, effectively ameliorates withdrawal symptoms, and decreases opioid overdose and mortality. However, buprenorphine remains under-utilized. Despite its low potential for misuse, research has reported wide use of non-prescribed buprenorphine, seemingly for its effectiveness in treating withdrawal and helping to maintain sobriety. We designed our study to describe patient experiences with both prescribed and non-prescribed buprenorphine usage and to identify potential disparities in buprenorphine access within a high-risk population of patients with OUD.
This was a cross-sectional study conducted in the emergency department (ED) of a large inner-city university hospital from January 15, 2015, through April 30, 2018. Patients were eligible to participate in the study if they presented with opioid intoxication at there appear to be racial and other disparities in buprenorphine prescribing, further limiting access to patients. Buprenorphine access needs to be expanded to satisfy the unmet need for appropriate treatment of those struggling with OUD, with particular attention to older and nonwhite patients.
Medication for opioid use disorder (MOUD) is associated with substantial reductions in the risk of mortality, and American and Canadian guidelines recommend it as part of the full range of available treatments for youth with opioid use disorder (OUD). We estimated the OUD cascade of care for all adolescents (ages 12-18) and young adults (19-24) with OUD in British Columbia, Canada (BC) in 2018.
Using a provincial-level linkage of six health administrative databases, we classified youth with OUD as adolescents (ages 12-18) or young adults (19-24) to compare with older adults (≥25) and described key factors known to influence engagement in health care. The eight-stage cascade of care included diagnosed with OUD, ever engaged in MOUD, recently in MOUD, currently in MOUD, and retained in MOUD for ≥1month, ≥3months, ≥12months, ≥24months.
We identified 4048 youth diagnosed with OUD as of September 30, 2018 (6.3% of all people with OUD). Most were young adults, aged 19-24 (n=3602; 89.0% of all youth), a majority of whom were males (n=1984; 55.1%). In contrast, adolescents diagnosed with OUD (n=446; 11.0% of all youth) were mostly females (n=287; 64.4%). Compared to adolescents, there were more young adults diagnosed with OUD ever engaged in MOUD (71.4% v. 36.5%), currently on MOUD (29.3% v. 16.8%), and retained in care for ≥1year (8.6% v. 2.0%).
A high proportion of youth aged 12-24 diagnosed with OUD in a health care setting in British Columbia received MOUD yet continued engagement is infrequent, particularly for adolescents. Long-term treatment plans for youth need to consider including MOUD when appropriate as part of tailored, youth-friendly services.

Methadone use for the management of opioid dependency during pregnancy is commonplace. Methadone levels are altered during pregnancy due to changes in maternal physiology. Despite this, a paucity of data exist regarding the most appropriate optimal dosing regimens during pregnancy.
This study applied a pharmacokinetic modeling approach to examine gestational changes in R- and S-methadone concentrations in maternal plasma and fetal (cord) blood. This study did so to derive a theoretical optimal dosing regimen during pregnancy, and to identify the impact of Cytochromes P450 (CYP) 2B6 and 2C19 polymorphisms on methadone maternal and fetal pharmacokinetics.
The study noted significant decreases in maternal R- and S-methadone plasma concentrations during gestation, with concomitant increases in fetal levels. At a dose of 90 mg once daily, 75% (R-) and 94% (S-) of maternal methadone trough levels were below the lower therapeutic window at term (week 40). The developed optimal dosing regimen escalated doses to 110 mg by week 5, followed by 10 mg increments every 5 weeks up to a maximum of 180 mg once daily near term.
