The intertwined expansion of telehealth and buprenorphine access from a prescriber hub.
In this manuscript, we describe how efforts to increase access to buprenorphine for Opioid Use Disorder (OUD) through a telemedicine hub before and since the COVID-19 pandemic have played out in the Veterans Healthcare Administration (VHA) in New England. We look at how the COVID-19 pandemic and subsequent spike in opioid overdoses tilted the risk: benefit calculation for tele-prescribing a controlled substance such as buprenorphine toward expanding access to tele-buprenorphine. We conclude that there is a need for tele-buprenorphine hubs that can fill gaps in geographically dispersed healthcare systems.

The Colorado National Collaborative: A public health approach to suicide prevention.
Suicide rates in the United States have risen dramatically during the 21st century despite national, state and local level commitments to prevention, improvements in the development and delivery of evidence-informed prevention approaches, and advances in epidemiological capacity to identify areas for targeted intervention. Complex problems require comprehensive solutions. In Colorado, that solution is a comprehensive, integrated public health collaboration that aligns diverse community and programmatic efforts across the prevention continuum. The Colorado National Collaborative (CNC) is pursuing a real-world test of the public health approach to suicide prevention by helping community coalitions deliver a package of evidence-informed activities in geographically defined community systems. ⋯ The CNC includes data-driven identification of populations at risk of suicide, community identification of protective factors, and true collaboration between prevention experts at the national, state, and local level in implementing a comprehensive approach to prevention. Lessons learned are discussed.

Polysubstance use trends and variability among individuals with opioid use disorder in rural versus urban settings.
Rural areas of the United States have been disproportionately impacted by the opioid epidemic, exacerbated by COVID-19-related economic upheavals. While polysubstance use is an important determinant of overdose risk, variability in polysubstance use as a result of numerous factors (e.g., access, preference) has yet to be described, particularly among rural persons with opioid use disorder (PWOUD). Survey data on past-month use of prescription and illicit opioids and 12 non-opioid psychoactive drug classes were analyzed from a national sample of rural (n = 3872) and urban (n = 8153) residents entering treatment for OUD from 2012 to 2019. ⋯ Polyprescription was highest in rural areas, with illicit opioid-focused use highest in urban areas. Demographic characteristics, co-morbid conditions and healthcare coverage were all associated with between-group differences. There is significant variability in polysubstance use that may identify specific prevention and treatment needs for subpopulations of OUD patients: interventions focused on reducing opioid prescriptions, early engagement with mental health resources, wider distribution of naloxone, and screening/treatment plans that take into account the use of multiple substances.

A candidate biological network formed by genes from genomic and hypothesis-free scans of suicide.
Information about genes and the biology of suicidal behavior (SB) is noisy due to heterogenous outcomes (suicide attempts or deaths), as well as many different genes and overlapping biological processes implicated. One approach to test the unbiased biological coherence of disease genes, is to use genes from hypothesis-free genetic scans and to investigate if they aggregate close to each other in cellular gene and protein interaction networks ("interactomes"). Therefore, we used network methods to study the biological coherence among genes (n = 229) from genome-wide association studies (GWAS) and whole exome sequencing (WES) of suicide outcome. ⋯ We identified a subset of GWAS+WES "core" genes (n = 54) which are the most proximal to each other in the context of three interactome assemblies, and present a candidate network module of suicide which is specific for nervous system tissues. The n = 54 most proximal "core" genes showed overrepresentation of synaptic and nervous system development genes, as well as network paths to other SB genes having increased evidence diversity. Overall, results suggested the existence of a coherent biology in suicide outcome and provide unbiased biological support concerning links to other SB genes, as well as e.g. bipolar disorder, excitatory/inhibitory function and ketamine treatment in SB.

Long-acting buprenorphine injectables: Opportunity to improve opioid use disorder treatment among rural populations.
The opioid epidemic continues with escalating overdose deaths further exacerbated by the coronavirus pandemic, despite having efficacious medication treatments for opioid use disorder (MOUD). Most persons with OUD remain undiagnosed, without ever receiving MOUD, and even among those who initiate MOUD, retention is infrequently longer than 6 months (Williams et al., 2019). Treatment access remains particularly problematic in rural areas that often have few providers and limited resources (Ghertner, 2019). ⋯ They hold promise to improve treatment access and retention by decreasing risks of nonadherence, diversion and misuse and may be particularly attractive during a pandemic in order to minimize provider and pharmacy contacts (Roberts et al., 2020) and help improve access to care in rural areas. There are several ongoing evaluations of LAB injectables in large multi-site randomized clinical trials sponsored by the National Institute on Drug Abuse and Veterans Administration Office of Research and Development in settings with special populations that exist in both urban and rural settings. Understanding the potential clinical benefits of LAB injectables along the care continuum, particularly for rural areas is essential to successful implementation in the complex healthcare system.
