Successful engagement in buprenorphine treatment among hospitalized patients with opioid use disorder and trauma.
The opioid epidemic continues to cause significant morbidity and mortality. Although there are effective medications for opioid use disorder (OUD), a minority of patients receive these treatments. OUD is common among patients hospitalized for traumatic injury and hospitalization could be an opportunity to initiate medications and link to ongoing buprenorphine care. ⋯ Among hospitalized patients with OUD who initiate buprenorphine, those who were hospitalized for trauma were at least as likely to link to out-patient treatment. Trauma admissions represent an important opportunity for diagnosing and linking patients with OUD to buprenorphine treatment.

Evaluation of the rewarding effects of mitragynine and 7-hydroxymitragynine in an intracranial self-stimulation procedure in male and female rats.
Kratom (Mitragyna speciosa Korth.) has been used in Southeast Asia for hundreds of years to increase energy, for relaxation, and to diminish opioid withdrawal. Kratom use has recently spread to Western countries. Kratom could potentially be used for the treatment of opioid withdrawal and pain, but more insight is needed into its abuse potential. Therefore, we investigated the rewarding properties of the primary kratom alkaloid mitragynine and its active metabolite 7-hydroxymitragynine, and morphine as a reference drug in male and female rats. These compounds have agonist activity at mu-opioid receptors. ⋯ These initial findings indicate that mitragynine and 7-hydroxymitragynine are not rewarding in the ICSS procedure. The present results suggest that these kratom alkaloids do not have abuse potential.

Poor sleep quality and insomnia have been associated with the use of tobacco, alcohol, and cannabis, but it is unclear if there is a causal link. In this Mendelian Randomization (MR) study we examine if insomnia causes substance use and/or if substance use causes insomnia. ⋯ There were unidirectional effects of liability to insomnia on alcohol dependence and cannabis initiation, and bidirectional effects between liability to insomnia and smoking measures. Bidirectional effects between smoking and insomnia might give rise to a vicious circle. Future research should investigate if interventions aimed at insomnia are beneficial for substance use treatment.

Signal of increased opioid overdose during COVID-19 from emergency medical services data.
Individuals with opioid use disorder may be at heightened risk of opioid overdose during the COVID-19 period of social isolation, economic distress, and disrupted treatment services delivery. This study evaluated changes in daily number of Kentucky emergency medical services (EMS) runs for opioid overdose between January 14, 2020 and April 26, 2020. ⋯ This Kentucky-specific study provides empirical evidence for concerns that opioid overdoses are rising during the COVID-19 pandemic and calls for sharing of observations and analyses from different regions and surveillance systems with timely data collection (e.g., EMS data, syndromic surveillance data for ED visits) to improve our understanding of the situation, inform proactive response, and prevent another big wave of opioid overdoses in our communities.

Pain-related anxiety, sex, and co-use of alcohol and prescription opioids among adults with chronic low back pain.
Both alcohol and prescription opioid use/misuse are highly prevalent among individuals with chronic pain. Co-use of alcohol and prescription opioids is also common, despite contraindications due to increased risk of negative health effects and mortality. There is evidence that pain-related anxiety (i.e., the tendency to respond to pain with anxiety or fear) may be associated with heavier drinking and prescription opioid use/co-use, and that these associations may be especially salient among men. ⋯ These findings contribute to a growing literature suggesting that pain-related anxiety is an important transdiagnostic factor in pain and alcohol and prescription opioid use/co-use, perhaps especially among males.
