Introduction: Medications for addiction treatment (MAT) are the evidence-based standard of care for treatment of opioid use disorder (OUD), but stigma continues to surround their use. We conducted an exploratory study to characterize perceptions of different types of MAT among people who use drugs.Methods: We conducted this qualitative study in adults with a history of non-medical opioid use who presented to an emergency department for complications of OUD. A semi-structured interview that explored knowledge, perceptions, and attitudes toward MAT was administered, and applied thematic analysis conducted.Results: We enrolled 20 adults. All participants had prior experience with MAT. Among participants indicating a preferred treatment modality, buprenorphine was the commonly favored agent. Previous experience with prolonged withdrawal symptoms upon MAT discontinuation and the perception of “trading one drug for another” were common reasons for reluctance to engage in agonist or partial-agonist therapy. While some participants preferred treatment with naltrexone, others were unwilling to initiate antagonist therapy due to fear of precipitated withdrawal. Most participants strongly considered the aversive nature of MAT discontinuation as a barrier to initiating treatment. Participants overall viewed MAT positively, but many had strong preferences for a particular agent.Conclusion: The anticipation of withdrawal symptoms during initiation and cessation of treatment affected willingness to engage in a specific therapy. Future educational materials for people who use drugs may focus on comparisons of respective benefits and drawbacks of agonists, partial agonists, and antagonists. Emergency clinicians must be prepared to answer questions about MAT discontinuation to effectively engage patients with OUD.

Introduction: Bystander naloxone distribution is an important component of public health initiatives to decrease opioid-related deaths. While there is evidence supporting naloxone distribution programs, the effects of increasing naloxone availability on the behavior of people who use drugs have not been adequately delineated. In this study we sought to 1) evaluate whether individuals’ drug use patterns have changed due to naloxone availability; and 2) explore individuals’ knowledge of, access to, experiences with, and perceptions of naloxone.Methods: We conducted a pilot study of adults presenting to the emergency department whose medical history included non-medical opioid use. Semi-structured interviews were conducted with participants and thematic analysis was used to code and analyze interview transcripts.Results: Ten participants completed the study. All were aware of naloxone by brand name (Narcan) and had been trained in its use, and all but one had either currently or previously possessed a kit. Barriers to naloxone administration included fear of legal repercussions, not having it available, and a desire to avoid interrupting another user’s “high.” Of the eight participants who reported being revived with naloxone at least once during their lifetime, all described experiencing a noxious physical response and expressed a desire to avoid receiving it again. Furthermore, participants did not report increasing their use of opioids when naloxone was available.Conclusions: Participants were accepting of and knowledgeable about naloxone, and were willing to administer naloxone to save a life. Participants tended to use opioids more cautiously when naloxone was present due to fears of experiencing precipitated withdrawal. This study provides preliminary evidence countering the unsubstantiated narrative that increased naloxone availability begets more high-risk opioid use and further supports increasing naloxone access.

Background: In 2020, there were 36.7 million reported falls among older adults (65+) in the United States. Ethanol and other sedating substances may increase fall risk among older adults due to their effect on cognitive and physical function. We estimate the prevalence of these substances in blood specimens of older adults presenting with a fall injury at selected trauma centers. Methods: The initial study collected blood specimens from May 2020 through July 2021 from adults undergoing a trauma team evaluation at selected United States Level 1 trauma centers. We limited our study to older adults evaluated after a fall (n = 1,365) and selected a random sample (n = 300) based on age, sex, and trauma-center quotas. Medical health records and blood specimens obtained at trauma center presentation were analyzed. We estimated the prevalence of ethanol, benzodiazepines, cannabinoids, and opioids in the blood specimens. Two-sample tests of binomial proportions and Chi-square two-tailed tests were used to compare prevalence estimates of substances by demographic characteristics. Results: At least one substance was detected among 31.3% of samples analyzed. Prevalences of specific substances detected were 9.3% (95% CI: 6.0–12.6%) for benzodiazepines, 4.3% (95% CI: 2.0–6.7%) for cannabinoids, 8.0% (95% CI: 5.2–11.7%) for ethanol, and 15.0% (95% CI: 10.9–19.1%) for opioids. There were 18 deaths (6%; 95% CI: 3.6–9.3%). One-third of decedents had at least one substance detected in their blood. Discussion: Opioids were the most frequently detected substance, followed by benzodiazepines, ethanol, and cannabinoids. Substance use prevalence was not uniform across demographics, with differences observed by sex and age. Conclusions: This study provides insight into the frequency of the presence of substances that may contribute to fall risk and serious injury among older adults. Screening older adults for substances that impair cognitive and physical function can enhance clinical fall prevention efforts. [ABSTRACT FROM AUTHOR]

Since 2010, medical toxicology physicians from the American College of Medical Toxicology (ACMT) Toxicology Investigators Consortium (ToxIC) have provided reports on their in-hospital and clinic patient consultations to a national case registry, known as the ToxIC Core Registry. De-identified 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 thirteenth annual report provides data from 7206 patients entered into the Core Registry in 2022 by 35 participating sites comprising 52 distinct healthcare facilities, bringing the total case count to 94,939. Opioid analgesics were the most commonly reported exposure agent class (15.9%), followed by ethanol (14.9%), non-opioid analgesic (12.8%), and antidepressants (8.0%). Opioids were the leading agent of exposure for the first time in 2022 since the Core Registry started. There were 118 fatalities (case fatality rate of 1.6%). Additional descriptive analyses in this annual report were conducted to describe the location of the patient during hospitalization, telemedicine consultations, and addiction medicine treatments.

Introduction: Caffeine overdose, while uncommon, can be life threatening with hemodynamic and neurological complications and often requires intensive monitoring and critical management. Case Report: We report a case of a 23‐year‐old male who ingested approximately 24 g of caffeine in a suicidal attempt and developed cardiopulmonary complications. He was resuscitated, and hemodialysis was performed with successful recovery. Conclusion: Hemodialysis appears to effectively remove caffeine from the blood system and can be lifesaving in severe caffeine overdose. [ABSTRACT FROM AUTHOR]

The ubiquitin‐like protein Hub1/UBL‐5 associates with proteins non‐covalently. Hub1 promotes alternative splicing and splicing of precursor mRNAs with weak introns in yeast and mammalian cells; however, its splicing function has remained elusive in multicellular organisms. Here, we demonstrate the splicing function of Hub1/UBL‐5 in the free‐living nematode Caenorhabditis elegans. Hub1/UBL‐5 binds to the HIND‐containing splicing factors Snu66/SART‐1 and PRP‐38 and associates with other spliceosomal proteins. C. elegans hub1/ubl‐5 mutants die at the Larval 3 stage and show splicing defects for selected targets, similar to the mutants in yeast and mammalian cells. UBL‐5 complemented growth and splicing defects in Schizosaccharomyces pombe hub1 mutants, confirming its functional conservation. Thus, UBL‐5 is important for C. elegans development and plays a conserved pre‐mRNA splicing function. [ABSTRACT FROM AUTHOR]
