Social housing conditions influence morphine dependence and the extinction of morphine place preference in adolescent mice.
Adolescent opioid abuse is on the rise, and current treatments are not effective in reducing rates of relapse. Our previous studies demonstrated that social housing conditions alter the acquisition rate of morphine conditioned place preference (CPP) in adolescent mice. Specifically, the acquisition rate of morphine CPP is slower in morphine-treated animals housed with drug-naïve animals. Thus, here we tested the effect of social housing conditions on the development of morphine dependence and the extinction rate of an acquired morphine CPP. ⋯ Social housing conditions modulate morphine dependence and the extinction rate of morphine CPP. Extinction testing is relevant to human addiction because rehabilitations like extinction therapy may be used to aid human addicts in maintaining abstinence from drug use.

Harms associated with prescription opioids are a major and increasing public health concern. Prescribing of opioids for inpatients may contribute to the problem, especially if primary care practitioners continue opioid therapy that is initiated in hospital. ⋯ Among opioid-naive patients admitted to the internal medicine unit, opioids were prescribed for about 1 in 5 patients, and less than one-third of these patients were continued on opioids at the time of discharge. These results, if replicated elsewhere, suggest that efforts to improve opioid prescribing and reduce attendant harm should be focused primarily on the outpatient setting.

Randomized Controlled Trial Multicenter Study Comparative StudyDesign considerations for point-of-care clinical trials comparing methadone and buprenorphine treatment for opioid dependence in pregnancy and for neonatal abstinence syndrome.
In recent years, the U.S. has experienced a significant increase in the prevalence of pregnant opioid-dependent women and of neonatal abstinence syndrome (NAS), which is caused by withdrawal from in-utero drug exposure. While methadone-maintenance currently is the standard of care for opioid dependence during pregnancy, research suggests that buprenorphine-maintenance may be associated with shorter infant hospital lengths of stay (LOS) relative to methadone-maintenance. There is no "gold standard" treatment for NAS but there is evidence that buprenorphine, relative to morphine or methadone, treatment may reduce LOS and length of treatment. ⋯ This pair of planned POCCTs would evaluate the comparative effectiveness of treatments for opioid dependence during pregnancy and for NAS. The results could have a significant impact on practice.

The objective of this study was to develop metrics to assess opioid prescribing behavior as part of the evaluation of the Extended-Release/Long-Acting (ER/LA) Opioid Analgesic Risk Evaluation and Mitigation Strategies (REMS). ⋯ Investigators propose three metrics to monitor changes in prescribing behaviors for opioid analgesics that might be used to evaluate the ER/LA Opioid Analgesics REMS. Low frequencies of patients, particularly those >85 years, were likely to be opioid tolerant prior to receiving prescriptions for opioid-tolerant-only ERO.

Substance use disorders are common in primary care settings, but detection, assessment, and management are seldom undertaken. Substantial evidence supports alcohol screening and brief intervention for risky drinking, and pharmacotherapy is effective for alcohol use disorders. Substance use disorders can complicate the management of chronic noncancer pain, making routine monitoring and assessment for substance use disorders an important aspect of long-term opioid prescribing. Patients with opioid use disorders can be effectively treated with methadone in opioid treatment programs or with buprenorphine in the primary care setting.
