How cellular adaptations give rise to opioid analgesic tolerance to opioids like morphine is not well understood. For one, pain is a complex phenomenon comprising both sensory and affective components, largely mediated through separate circuits. Glutamatergic projections from the medial thalamus (MThal) to the anterior cingulate cortex (ACC) are implicated in processing of affective pain, … Read more

Opioid-related overdoses account for almost half of all drug overdose deaths in the United States and cause more preventable deaths every year than car crashes.

BACKGROUND/IMPORTANCE: Considerable attention has been paid to identifying and mitigating perioperative opioid-related harms. However, rates of postsurgical opioid use disorder (OUD) and overdose, along with associated risk factors, have not been clearly defined. OBJECTIVE: Evaluate the evidence connecting perioperative opioid prescribing with postoperative OUD and overdose, compare these data with evidence from the addiction literature, … Read more
INTRODUCTION: Contingency management (CM) is one of the most effective interventions for substance use disorders (SUDs), including stimulant use disorder. In the United States, the Veterans Health Administration (VHA) led the largest-scale rollout of CM in the US to date, but little is known about characteristics of patients treated and CM clinical practices. METHODS: In … Read more
PURPOSE: National studies examining alcohol and other drug use by sexual orientation have been primarily cross-sectional. Understanding changes in sexual orientation over time may further elucidate the mechanisms behind sexual orientation differences in alcohol and other drug use. This national longitudinal study examines changes in sexual orientation across four waves (2013-2019), and the associations with … Read more
OBJECTIVE: This study examined daily associations between alcohol use, cannabis use, and simultaneous alcohol and cannabis/marijuana (SAM) use with the likelihood of hooking up (uncommitted sexual encounter that may or may not include intercourse). METHOD: We used a longitudinal measurement burst ecological momentary assessment (EMA) design with 3-week EMA bursts with daily measurements repeated quarterly … Read more
BACKGROUND: Pain is challenging after recovery from total knee arthroplasty (TKA) and total hip arthroplasty (THA) procedures, and patients often receive prescription opioids. However, opioid consumption by patients remains unclear, and unused opioids may lead to risks including misuse and diversion. The objective of this systematic review and meta-analysis was to compare prescription size versus … Read more
BACKGROUND: There remains a paucity of data for vulvar surgery outcomes in gynecologic oncology in the era of Enhanced Recovery After Surgery (ERAS) ®. As such, the primary objective is to assess the impact of patient and procedural factors on patient reported postoperative opioid usage following vulvar surgery. Secondary objective is to create a tailored … Read more
OBJECTIVE: To examine the association of universal question-based screening for prenatal substance use on racial inequities in prenatal and newborn drug testing. METHODS: We conducted a retrospective cohort study of 32,802 live births of patients receiving prenatal care at an academic medical center in the midwestern United States from 2014 to 2022, before and after … Read more
