Spatial patterns of rural opioid-related hospital emergency department visits: A machine learning analysis.

As opioid-related overdose emergency department visits continue to rise in the United States, there is a need to understand the location and magnitude of the crisis, especially in at-risk rural areas. We analyzed sets of ZIP code level electronic health records for emergency department visits from 6 hospitals for two rural regions of Maryland with higher opioid-related overdose rates. Analysis of the demographics of visits found Black or African American emergency department visits in both rural regions were higher than the proportion of their population per region.

Effectiveness of Conditioned Open-label Placebo With Methadone in Treatment of Opioid Use Disorder: A Randomized Clinical Trial.

Importance: Methadone treatment is the most effective evidence-based treatment for opioid use disorder (OUD), but challenges related to dosing and premature treatment dropout argue for adjunct interventions to improve outcomes. One potential behavioral intervention with low risk involves harnessing placebo effects.

Objective: To determine the effect of a pharmacologically conditioned open-label placebo (C-OLP) on 90-day methadone dose, retention, drug use, withdrawal, craving, quality of life, and sleep.

Emergency Department Drug Surveillance (EDDS) hospital's urinalysis results compared with expanded re-testing by an independent laboratory, a pilot study.

Introduction: Most hospital urine toxicology screens detect a fixed, limited set of common substances. These tests are fast and accurate but may miss emerging trends in substance use in the community and clinical acumen alone is insufficient for identifying new substances.

Methods: This prospective cohort study examined de-identified urine specimens obtained from patients visiting the Emergency Department (ED) at Prince George's Hospital Center (PGHC), between October 15, 2019 to November 6, 2019 and tested positive for one or more substances.

Toward a National System of Expanded Testing of Existing Urine Specimens: The Drug Outbreak Testing Service (DOTS).

Background: NIDA's National Drug Early Warning System (NDEWS) was established in 2014 with the mission of identifying and monitoring emerging drugs in the United States. Identification of emerging drugs has been complicated, however, by the rapid development of novel psychoactive substances such that users often cannot identify and report the drugs they have ingested. Biologic testing of urine, hair or blood is the only way to reliably identify the substances recently used.

Race-based differences in drug use prior to onset of opioid use disorder.

Rates of opioid use disorder (OUD) have increased dramatically over the past two decades, a rise that has been accompanied by changing demographics of those affected. Early exposure to drugs is a known risk factor for later development of opioid use disorder; but how and whether this risk factor may differ between racial groups is unknown. Our study seeks to identify race differences in self-report of current and past substance use in OUD-diagnosed treatment-seeking individuals.

Open-label dose-extending placebos for opioid use disorder: a protocol for a randomised controlled clinical trial with methadone treatment.

Introduction: More than 2 million individuals in the USA have an opioid use disorder (OUD). Methadone maintenance treatment is the gold standard of medication-based treatment for OUD, but high-dose methadone is associated with cardiotoxicity and respiratory complications, among other side effects. These adverse effects make enhancing the effectiveness of lower doses of methadone an attractive therapeutic goal.

Opioid-galanin receptor heteromers mediate the dopaminergic effects of opioids.

Identifying non-addictive opioid medications is a high priority in medical sciences, but μ-opioid receptors mediate both the analgesic and addictive effects of opioids. We found a significant pharmacodynamic difference between morphine and methadone that is determined entirely by heteromerization of μ-opioid receptors with galanin Gal1 receptors, rendering a profound decrease in the potency of methadone. This was explained by methadone's weaker proficiency to activate the dopaminergic system as compared to morphine and predicted a dissociation of therapeutic versus euphoric effects of methadone, which was corroborated by a significantly lower incidence of self-report of "high" in methadone-maintained patients.

Assets, challenges, and the potential of technology for nutrition education in rural communities.

Objective: To examine assets of and challenges to getting adequate nutrition and physical activity among low-income rural residents, and the potential for technology to provide health education.

Methods: Environmental scans and community stakeholder interviews were conducted in 5 rural counties in Maryland. During environmental scans, stakeholders guided tours around each county to explore community services and resources for nutrition, physical activity and technology.

Rural eHealth nutrition education for limited-income families: an iterative and user-centered design approach.

Background: Adult women living in rural areas have high rates of obesity. Although rural populations have been deemed hard to reach, Internet-based programming is becoming a viable strategy as rural Internet access increases. However, when people are able to get online, they may not find information designed for them and their needs, especially harder to reach populations.

Assessment of the nutrition and physical activity education needs of low-income, rural mothers: can technology play a role?

The purpose of this study was to examine the perceptions of low-income, rural mothers regarding their need for nutrition and physical activity education and the role of technology in addressing those needs. Quantitative and qualitative research was combined to examine the nature and scope of the issues faced by this target population. Women who were currently receiving food stamps and had children in nursery school to eighth grade were recruited through a state database to participate in a telephone survey (N = 146) and focus groups (N = 56).
