Groundbreaking Research from NIDA Addressing the Challenges of the Opioid Epidemic
The 2024 ACMT Ward and Ryan Donovan Memorial Fund lecture was presented by Dr. Nora Volkow, the director of the National Institute on Drug Abuse (NIDA) at the National Institutes of Health (NIH). This article in an edited version of her keynote address during ACMT's 2024 Annual Scientific Meeting. During the course of her talk, Dr. Volkow discussed the historical factors contributing to the ongoing global opioid epidemic, examined the evidence behind different front-line and policy strategies used to battle the opioid epidemic, and highlighted the importance of recent cultural changes that support more deliberate screening for substance use disorders and pathways for initiating treatment of opioid use disorders in vulnerable populations. An urgent need exists to improve inclusion of social and structural determinants of health in implementation science addressing opioid use disorders, with better attention to special populations, including Native American Indians and Alaskan Natives, African Americans, those over 65 years of age, and teenagers.
The American College of Medical Toxicology Annual Scientific Meeting: A Look Back and the Path Forward
More than 20 years that have elapsed since the inaugural American College of Medical Toxicology Spring Conference in 2002. During this time, the now ACMT Annual Scientific Meeting has grown in many ways, as demonstrated by the increase in attendance and abstract submissions, and diversification of educational offerings, and partners. Most importantly, the scientific rigor and presentation of new knowledge has continued to mature, and the conference is now firmly rooted in the annual educational schedule for medical toxicologists. In anticipation of the upcoming 2025 ASM, we reflect upon the evolution and growth of ACMT's research and educational agendas, and the Annual Scientific Meeting itself.
Medical Toxicology vs. Emergency Medicine and Internal Medicine - Are We Really Full of Case Reports?
Case reports are perceived as having diminished value relative to other study designs. It has been said that medical toxicology (MT) is based largely upon case report literature and thought to be unique in this regard. We sought to quantify recent MT publication of case reports compared with top periodicals from emergency medicine (EM) and internal medicine (IM) journals.
Cyanide Medical Countermeasure Development: Assessing the Efficacy of Intramuscular Sodium Tetrathionate for the Treatment of Acute, Severe Cyanide Toxicity in Swine (Sus scrofa)
Given its availability and lethality, cyanide has potential for weaponization and thus has the attention of several governmental agencies. In large scale exposure scenarios, an effective countermeasure that can be administered quickly and in low volume intramuscularly may prove valuable because IV medications may have limited practical applications in these situations. Sodium tetrathionate, a potential cyanide antidote, is a compound that provides sulfur to rhodanese, the enzyme that detoxifies cyanide endogenously. Additionally, sodium tetrathionate has been reported to directly react with cyanide and is effective when administered intramuscularly. In this study, we assess the efficacy of sodium tetrathionate, when administered intramuscularly for the treatment of acute, oral cyanide poisoning in swine.
Substance Use among Youth Presenting to the Pediatric Emergency Department
Our primary objective was to determine the frequency and type of substance use in youth presenting to our pediatric ED (PED). Our secondary objective was to identify characteristics associated with higher-risk substance use.
Leveraging Trauma Informed Care for Digital Health Intervention Development in Opioid Use Disorder
Digital health refers to the use of information and communication technologies in medicine (including smartphone apps, wearables, other non-invasive sensors, informatics and telehealth platforms) to prevent illness, deliver treatment, and promote wellness. This rapidly proliferating group of technologies has the potential to reduce harm for people with opioid use disorder (OUD) and facilitate the recovery process; however, development in this space for OUD has been slower compared to that for other medical conditions. Unique issues with OUD management surrounding patient provider relationships, interaction with the healthcare system, autonomy and trust sometimes hinder care approaches, including those in digital health. The trauma informed care framework (TIC), developed for use by organizations to support individuals who have experienced trauma, has particular applicability for digital health interventions in OUD care. This manuscript will serve as a review of TIC principles and how they can be applied to digital health interventions to increase access, equity, and empowerment for people with OUD. We will highlight representative current and pipeline digital technologies for OUD, challenges with these technologies, TIC models for OUD, and the integration of TIC principles into digital technology development to better serve people with OUD. Finally, we will posit strategies to incorporate the aforementioned principles into future research efforts. We ultimately aim to use TIC as a lens through which to develop digital technologies to help individuals with OUD while minimizing harm.
Assessment of Clinical Toxicological Resources in Countries Belonging to the World Health Organization's Regional Office of the Eastern Mediterranean
Poison Centers are vital to prevent and manage exposures to chemicals, toxins, and ionizing radiation. However, many countries still lack sufficient poison information center services. Within the World Health Organization's Eastern Mediterranean Regional Office (EMRO) region, we were not able to identify a formal assessment of its toxicological resources. We sought to assess the clinical toxicological resources in the EMRO region and the attitudes, needs, and perspective of the workforce in that region. METHODS: This was a two part survey study. First, we developed a poison center questionnaire and scoring system based on the World Health Organization's Guidelines for Establishing a Poison Center; this instrument was administered by phone to poison center directors and faculty in the EMRO region. Questions assessed for the presence or absence of important poison center capabilities listed in the WHO guidelines, and points were assigned based on response. Secondly, we administered an electronic workforce survey to clinical toxicology professionals in the region; participant eligibility for the workforce survey was based on the membership roster of MENATOX.
The Toxicology Investigators Consortium 2023 Annual Report
Since 2010, the American College of Medical Toxicology (ACMT) Toxicology Investigators Consortium (ToxIC) has maintained the ToxIC Core Registry, a national case registry of in-hospital and clinic patient consultations submitted by medical toxicology physicians. Deidentified patient data entered into the registry includes patient demographics, reason for medical toxicology evaluation, exposure agents, clinical signs and symptoms, treatments and antidotes administered, and mortality. This fourteenth annual report provides data from 7392 patients entered into the Core Registry in 2023 by 36 participating sites comprising 61 distinct healthcare facilities, bringing the total case count to 102331 between 2010 and 2023. Ethanol was the most commonly reported exposure agent class (24.4%), followed by opioids (22.7%), non-opioid analgesics (16.7%), and antidepressants (11.7%). For the first time since the registry's initiation, in 2023, ethanol was the leading agent of exposure. There were 98 fatalities (case fatality rate of 1.3%). Additional descriptive analyses in this annual report were conducted to describe the reasons for medical toxicology consultation by age in 2023, and yearly trends for opioid and psychoactive exposures, physostigmine and rivastigmine treatments, and acetaminophen exposures treated with fomepizole.

Pharmacobezoar Associated Prolonged Clinical Course in a Patient with Immediate Release Quetiapine Overdose
Quetiapine is available in both immediate-release (IR) and extended-release (XR) formulations. Quetiapine XR overdose is known to cause delayed increase in serum quetiapine concentrations. However, it is not certain whether quetiapine IR overdose would similarly cause a delayed increase in serum quetiapine concentrations.

Analytically Confirmed Intentional Overdose of the Antidepressant Vortioxetine
Vortioxetine is an antidepressant with a multimodal mechanism of action. It is used as a treatment option for patients with major depressive episodes. There have only been two previously reported non-fatal overdoses of vortioxetine; neither of these were analytically confirmed There has also been one case of serotonin syndrome potentially related to vortioxetine and two deaths where vortioxetine was detected. We report here a non-fatal analytically confirmed case of vortioxetine overdose.
Neurologic Deficits Following Oral Misuse of the Nasal Decongestant Propylhexedrine
Propylhexedrine is an over-the-counter nasal decongestant used recreationally for amphetamine-like effects. Prior reports have associated intravenous misuse with brainstem dysfunction and diplopia. This is a case of propylhexedrine ingestion resulting in neurological impairment with associated MRI findings.

Delta-8 Tetrahydrocannabinol Exposures Reported to US Poison Centers: Variations Among US States and Regions and Associations with Public Policy
This study investigated exposures involving ∆8-tetrahydrocannabinol (∆8-THC) reported to US poison centers (PCs), including variation among states and regions. It evaluated whether the ∆8-THC exposure rate was lower among states with ∆8-THC regulations and states where cannabis (∆9-THC) use was legal.
Attempted Self-Harm with Elemental Thallium Purchased Online: Case Report with Analytical Confirmation
Thallium is a highly toxic metal, with most publications demonstrating poisoning from thallium salts. We report on a patient with elevated serum and urine thallium concentrations from an intentional ingestion of elemental thallium purchased from the internet for self-harm.
Biostatistics and Epidemiology for the Toxicologist: Likelihood Ratios
Likelihood ratios compare two values (i.e., case rates) in order to illustrate the magnitude of the difference between the two. This ratio increases the confidence one can have in a diagnostic test from a different vantage point than that of sensitivity and specificity. The calculations of likelihood ratios are presented along with a simplified approach. Likelihood ratios are another tool the toxicologist should employ in their understanding of statistics and probability.
