Introduction: Whether prescription opioid exposure, duration, and dose are associated with cognitive function remains inconclusive.
Methods: A longitudinal cohort among 3097 older adults with chronic pain and without dementia was conducted using Health and Retirement Study (HRS) linked to Medicare data from 2006 to 2020. Prescription opioid exposure, cumulative use for ≥ 90 days, and high-dose use (≥ 90 morphine milligram equivalents [MME] daily) were assessed biennially. Memory score and dementia probability were derived from HRS cognitive measures and analyzed using linear mixed-effects models.
Results: Adjusted memory decline and dementia probability were not statistically different between patients with (vs. without) opioid exposure and between patients with cumulative use for ≥ 90 days (vs. < 90 days) but were higher between participants with high-dose opioid use (vs. low-dose) at the end of the follow-up.
Discussion: Prescription opioid exposure and duration were not associated, but high-dose opioid use was associated with greater memory decline and dementia probability.
Highlights: Opioid use versus no use was not related to memory decline and dementia probability. Long-term opioid use was not related to memory decline and dementia probability. High-dose opioid use was related to greater memory decline and dementia probability.

Cancer

Department of Biostatistics, Brown University School of Public Health, Providence, Rhode Island, USA.
Background: Opioid exposure during cancer therapy may increase long-term unsafe opioid prescribing. This study sought to determine the rates of coprescription of benzodiazepine and opioid medications and new persistent opioid use after surgical treatment of early-stage cancer.
Methods: A retrospective cohort study was conducted among a US veteran population via the Veterans Affairs Corporate Data Warehouse database.

Introduction: Exposure to prescription opioids following traumatic injury can increase the risk of developing tolerance, persistent opioid use and opioid use disorder. The mechanisms underlying opioid tolerance or dependence are not well understood, and no biomarkers predict risk. Opioid exposure causes epigenetic modifications, including alterations in microRNA (miRNA) expression.

Background: Although procedure-specific guidelines have been established for postoperative opioid prescribing in the elective setting, it is unknown to what extent prescriptions in the emergency setting adhere to these standards. Variation in opioid prescribing for emergency general surgery patients may represent context-appropriate deviation or an opportunity for improved stewardship.
Methods: Leveraging data from a statewide Acute Care Surgery collaborative, we identified patients undergoing 4 common procedures in the emergency setting: laparoscopic appendectomy, laparoscopic cholecystectomy, emergency hernia repair, and open colectomy.
Drug Alcohol Depend
August 2025
Brown University School of Public Health, Departments of Behavioral and Social Sciences and Epidemiology, Providence, RI, USA.
Background: Twelve state Medicaid programs limit the monthly number of covered prescriptions. Such cap policies may force enrollees to forego essential medications with important health consequences. We aimed to determine the impact of cap policies on acute care use and all-cause mortality among enrollees with opioid use disorder (OUD).

St. John's Newfoundland and Labrador, St. John's, NL, Canada.
Objective: To report the rate of prescription opioid use rates over a 5-year period for the population of Newfoundland and Labrador (NL), Canada, and to highlight patient demographics within this cohort.
Design: This retrospective cohort design used population-based pharmacy network prescription data from the province of NL to identify patients who were prescribed opioids from June 1, 2017, to June 1, 2022.
Setting: A cohort of adult and pediatric patients who were being prescribed opioids from June 1, 2017, to June 1, 2022, in NL.
