Pharmacological ablation of rostral ventromedial medulla (RVM) mu opioid receptor-expressing cells before peripheral nerve injury prevents the development of neuropathic pain. However, whether these neurons are required for the expression of established neuropathic pain is not known. Male Oprm1Cre heterozygous (MOR Cre ) or wild-type (MOR WT ) mice received AAV8-hSyn-DIO-hM4D(Gi)-mCherry in the RVM. ⋯ Sustained CNO in drinking water before PSNL prevented expression of chronic pain without affecting acute surgical pain; however, relief of chronic pain required sustained CNO treatment. Thus, in male mice, activity of spinally projecting RVM-MOR cells is required (1) for expression and manifestation of both sensory and affective dimensions of established neuropathic pain and (2) to promote descending facilitation that overcomes apparently intact descending inhibition to maintain chronic pain. Enhanced descending facilitation likely regulates the output signal from the spinal cord to the brain to shape the pain experience and may provide a mechanism for nonopioid management of pain.

The erector spinae plane block (ESPB) is a relatively new regional anesthetic procedure that provides analgesia below the erector spinae muscles in an interfascial plane. The indications for its use continue to expand as we learn more about this block. ⋯ The erector spinae block is a safe and cost-effective intervention in refractory postherpetic neuralgia.

More Americans died in 2021 from drug overdose than from vehicle accidents and firearms combined. Unlike earlier phases, the current epidemic is marked by its disproportionate impact on communities of color. This report investigates regional and substance-specific variations in racial disparities to generate possible insights into the various forces shaping these trends. ⋯ The opioid epidemic continues to expand, with particularly rapid acceleration in racially minoritized communities. The growing role of stimulants in opioid overdose deaths is a racialized phenomenon disproportionately impacting Black and Native Americans. Wide variation in state-level disparities suggest that structural racism impacts health in regionally specific ways, highlighting the need for regional solutions.

Connecticut Pediatric Opioid Poisoning Trends Surrounding the COVID-19 Pandemic.
Opioids are common substances involved in poisonings with increasing rates in fentanyl-related mortality since 2014. The COVID-19 pandemic compromised school attendance and supervision, which may have increased the risk of opioid ingestions in children. Our objective was to evaluate pediatric opioid poisonings in Connecticut before and during the COVID-19 pandemic. ⋯ Results of our study showed a rise in opioid poisonings among non-Hispanic Black and elementary school-aged children during the COVID-19 pandemic. Future prevention efforts may choose to further investigate and understand the trends in the more vulnerable groups.
