Randomized Controlled Trial Multicenter Study
A prospective, randomized, multicenter acceptability and safety study of direct buprenorphine/naloxone induction in heroin-dependent individuals.
To provide controlled data on direct induction with buprenorphine/naloxone (BNX) versus indirect buprenorphine (BPN)-to-BNX induction. ⋯ Direct buprenorphine/naloxone induction was a safe and effective strategy for maintenance treatment of opioid dependence. Response to high-dose direct buprenorphine/naloxone induction appears to be similar to indirect buprenorphine-to-buprenorphine/naloxone induction and was not associated with reports of intravenous buprenorphine/naloxone misuse.

Ketamine remains an important medicine in both specialist anaesthesia and aspects of pain management. At the same time, its use as a recreational drug has spread in many parts of the world during the past few years. There are now increasing concerns about the harmful physical and psychological consequences of repeated misuse of this drug. The aim of this review was to survey and integrate the research literature on physical, psychological and social harms of both acute and chronic ketamine use. ⋯ The implications of these findings are drawn out for treatment of ketamine-induced ulcerative cystitis in which interventions from urologists and from addiction specialists should be coordinated. Neurocognitive impairment in frequent users can impact negatively upon achievement in education and at work, and also compound addiction problems. Prevention and harm minimization campaigns are needed to alert young people to these harmful and potentially chronic effects of ketamine.

Adolescents with substance use disorders (SUD) have difficulties with cognitive, behavioral and affective regulation. White matter (WM) disorganization has been observed in adolescents with SUD and may be related to psychological dysregulation. This study compared adolescents with SUD and control adolescents to investigate relationships among psychological dysregulation, WM disorganization and SUD symptoms. ⋯ In adolescents, substance use disorder and psychological dysregulation appear to be associated with reduced frontoparietal network white matter maturation.

Alcohol-exposed pregnancies (AEP) are the direct cause of fetal alcohol spectrum disorders (FASD). This study examines drinking patterns among pregnant and non-pregnant women of childbearing age in Russia, a country with one of the highest levels of alcohol consumption in the world. ⋯ Russian women substantially reduce drinking after pregnancy recognition compared to pre-pregnancy levels. No reductions were found prior to pregnancy recognition, either when a woman might become pregnant or when she was trying to conceive. The pre-conception period presents a risk window and, therefore, a prevention opportunity.
