Much research has analyzed the spatial patterns of drug overdose events and identified features of the environment associated with heightened overdose levels. Generally absent from the literature are studies that analyze how unique trajectories of overdoses vary over time. We address this gap in the literature through an analysis of drug overdoses occurring in Passaic County, New Jersey from 2015 through 2019. A group-based trajectory analysis classifies block groups according to their overdose trends. A mixed-effects panel negative binomial regression model then examines the built environment and neighborhood characteristics associated with overall overdose levels. Results indicate that Passaic County block groups can be classified across three groups based upon their overdose levels over the study period: low and stable, low with moderate increase, and elevated and increasing. While the largest effects were observed for concentrated disadvantage in the regression analysis, most variables positively associated with overdose levels were built environment measures.

Development and preclinical testing of a naloxone prodrug depot for extended protection against opioid overdose.
Nat Commun
January 2025
Department of Pharmaceutical Sciences, Thomas J. Long School of Pharmacy, University of the Pacific, Stockton, CA, US.
The opioid crisis, driven by synthetic opioids like fentanyl, demands innovative solutions. The opioid antidote naloxone has a short action ( ~ 1 hour), requiring repeated doses. To address this, we present a new and simple naloxone prodrug delivery system repurposing a hydrophilic derivative of acoramidis, a potent transthyretin ligand.

Background: Identifying the most effective state laws and provisions to reduce opioid overdose deaths remains critical.
Methods: Using expert ratings of opioid laws, we developed annual state scores for three domains: opioid prescribing restrictions, harm reduction, and Medicaid treatment coverage. We modeled associations of state opioid policy domain scores with opioid-involved overdose death counts in 3133 counties, and among racial/ethnic subgroups in 1485 counties (2013-2020).
Challenges in the Management of Severe Serotonin Syndrome: A Case Report.

Psychiatry and Behavioral Sciences, Kaweah Delta Health Care District, Visalia, USA.
Serotonin syndrome (SS) is a potentially life-threatening condition that can result from excessive serotonergic activity, often due to SSRIs, formally known as selective serotonin reuptake inhibitors. The syndrome and its effects are often secondary to drug-drug interactions or dose-related. This case highlights a 47-year-old female who presents with a history of major depressive disorder, generalized anxiety disorder, and severe alcohol use disorder.

A woman in her 40s with a history of depression, diabetes, zinc deficiency and gastric bypass surgery presented to the emergency department following the intentional ingestion of ninety 50 mg tablets of zinc sulfate. She exhibited gastrointestinal distress without systemic toxicity. Imaging revealed radiopaque tablets in the abdomen, and her management was primarily supportive, focusing on symptom control and hydration.

Given the lack of accurate diagnostic methods of acetaminophen (APAP)-induced acute liver failure (ALF), the search for new biomarkers for its diagnosis is an urgent need. The aim of this study was to evaluate the role of bone morphogenetic protein 6 (BMP6) in APAP-induced ALF progression and its potential value as a biomarker of ALF. Hepatic and circulating BMP6 expression was assessed in APAP-treated mice and in serum samples from patients with APAP overdose.
