RÉSUMÉ
INTRODUCTION: Opioid dependence represents a public health crisis and can be observed after outpatient urologic procedures. The purpose of this study was to evaluate the risk of persistent opioid usage after radical orchiectomy for testicular cancer. MATERIALS AND METHODS: The TriNetX Research network database was queried for men between 15 and 45 years undergoing radical orchiectomy for a diagnosis of testicular cancer. All patients with N+ or M+ disease, prior opioid use, and patients who underwent chemotherapy, radiotherapy, or retroperitoneal lymph node dissection were excluded. Patients were stratified whether they were prescribed opioids or not at time of orchiectomy. The incidence of new, persistent opioid use, defined as a prescription for opioids between 3 and 15 months after orchiectomy, was evaluated. RESULTS: A total of 2,911 men underwent radical orchiectomy for testicular cancer, of which 89.8% were prescribed opioids at time of orchiectomy. After propensity score matching for age, race, and history of psychiatric diagnosis, 592 patients were included (296 received opioids, 296 did not). Overall, 0% of patients who did not receive postoperative opioids developed new persistent opioid use, whereas 10.5% of patients who received postoperative opioids developed new persistent opioid use. Patients prescribed postoperative opioids for orchiectomy had statistically higher risk difference of developing new persistent opioid use (Risk Difference: 10.5%; 95% CI: 7.0-14.0; Z: 5.7; P < 0.01). CONCLUSIONS: Postoperative opioid prescription following radical orchiectomy is significantly associated with developing new persistent opioid use, with 1 in 10 young men who received postoperative opioids obtaining a new prescription for opioids well beyond the postoperative period. Future efforts should emphasize nonopioid pathways for pain control following this generally minor procedure.

Introduction: Although psychoactive medicines (PMed) are needed in several psychiatric conditions, their use and misuse bear risks. We aimed at estimating the prevalence of PMed use and misuse. Methods: Data on all PMed prescribed in 2017 and dispensed in community pharmacies of the Lisbon and Tagus Valley region of Portugal (ARSLVT) were extracted from ARSLVT medicines' dispensing database. For 21 PMed among prescription opioids, benzodiazepines and z-drugs (BZDR), antidepressants (AD) and anticonvulsants (AC), we estimated the number of users of each PMed, and assessed PMed misuse by a set of proxy indicators for studying this practice: chronic use (use of ≥180 DDD during the study period) of PMed intended for short-term treatments, concomitant use of several PMed, in particular if involving long-term (≥ 30 days) opioid analgesic (OA) use, and doctor shopping (patients consulting several physicians in order to have access to a quantity higher than intended by each prescriber). Data were analysed using descriptive statistics and hypothesis testing, and multivariate logistic regression was used to explore potential factors affecting long-term concomitant treatment of chronic OA with other PMed. Results: PMed use prevalence was 21.7%: 6.6% for OA, 12.7% for benzodiazepines (BZD), 5.3% for AD and 2.8% for AC. BZDR were mainly prescribed in primary care and OA in hospital outpatients. Chronic use of PMed was observed in 25%, especially with sertraline and buprenorphine for opioid use disorder (long-term treatment), and lorazepam (short-term treatment). About 56.6% of OA chronic users were long-term concurrent users with other PMed, mainly BZDR. Risk of abuse was low for BZDR, whilst four opioids had meaningful doctor shopping indicators - fentanyl, opioid use disorder buprenorphine, morphine and hydromorphone. Conclusions: BZD are the main PMed used in ARSLVT, often chronically, especially lorazepam. Prevalence of OA use is low, although with higher risk of misuse than BZDR. Concomitant use of several PMed is frequent.
RÉSUMÉ
The opioid-abuse epidemic is a problem that continues to persist world-wide. As such, appropriately evaluating and treating such patients is crucial, especially when considering the various complications that may arise. In rare cases, opioid overdoses can be complicated by compartment syndrome, rhabdomyolysis, and acute renal failure. All three of these complications can result in life threatening emergencies. We present a case of a 38-year-old male who was brought to the emergency department after reportedly being found lying on the ground for an unknown period of time from suspected heroin overdose. He was initially treated with 2 milligrams (mg) of intramuscular naloxone en route via emergency medical services with appropriate response. Shortly after arrival to the emergency department, the patient complained of severe right lower extremity pain, paresthesia and paralysis. Patient developed acute lower extremity compartment syndrome that was further complicated by rhabdomyolysis and acute renal failure. While emergency medicine physicians are familiar with the common complications of heroin overdose including mental status changes, respiratory depression and gastrointestinal symptoms, they must also be familiar with the less common ones. Notably, acute compartment syndrome. Compartment syndrome is ultimately a clinical diagnosis and warrants emergent surgical consultation. Every patient presenting to the emergency department warrants a complete, thorough physical examination to evaluate for any and all life-threatening conditions, regardless of the presenting complaint.

OBJECTIVE: The PN Naloxone Nasal Swab (Pocket Naloxone Corp., Bethesda, MD) is a swab optimized for drug delivery and intended for use by non-medical personnel for the emergency treatment of opioid overdose. The aim of this study (PNC-20-003) is to determine the safety of this nasal swab in a real-world environment. METHODS: This was a single-institution, quantitative-qualitative prospective trial performed at an outpatient clinic. Patients with normal or abnormal nasal structure were recruited. A non-medically trained individual placed the nasal (soaked in fluorescein dye) on each side of the patient's nose. Endoscopy with recording was performed before and after swab placement. An independent reviewer rated degree of staining, mucosal bleeding, and trauma at nasal subsites. RESULTS: Videos from 32 nasal cavities (16 participants) were reviewed. All cavities had high intensity staining at the septum and the inferior turbinate. No patients had staining within the middle meatus, agger nasi, or olfactory regions. In patients with normal anatomy, obstructive nasal anatomy or prior nasal surgery, all cavities had staining near the nasal septum. Only 7 cavities (22 %) had minor bleeding defined as ooze that stopped in 1-2min, and 3 (9 %) had minor trauma defined as mucosal disruption less than 5mm. There were no significant differences in comparing pre- and post-swab nasal cavity, trauma, or bleeding exams. CONCLUSIONS: These study results showed that this swab is atraumatic to the nasal mucosal membranes when administered by non-medical personnel. Analysis suggests contact with targeted sites for drug absorption regardless of anatomy.

BACKGROUND: Despite strong and growing interest in ending the ongoing opioid health crisis, there has been limited success in reducing the prevalence of opioid addiction and the number of deaths associated with opioid overdoses. Further, 1 explanation for this is that existing interventions target those who are opiate-dependent but do not prevent opioid-naïve patients from becoming addicted. OBJECTIVE: Leveraging behavioral economics at the patient level could help patients successfully use, discontinue, and dispose of their opioid medications in an acute pain setting. The primary goal of this project is to evaluate the effect of the 3 versions of the Opioid Management for You (OPY) tool on measures of opioid use relative to the standard of care by leveraging a pragmatic randomized controlled trial (RCT). METHODS: A team of researchers from the Center for Learning Health System Sciences (CLHSS) at the University of Minnesota partnered with M Health Fairview to design, build, and test the 3 versions of the OPY tool: social influence, precommitment, and testimonial version. The tool is being built using the Epic Care Companion (Epic Inc) platform and interacts with the patient through their existing MyChart (Epic Systems Corporation) personal health record account, and Epic patient portal, accessed through a phone app or the MyChart website. We have demonstrated feasibility with pilot data of the social influence version of the OPY app by targeting our pilot to a specific cohort of patients undergoing upper-extremity procedures. This study will use a group sequential RCT design to test the impact of this important health system initiative. Patients who meet OPY inclusion criteria will be stratified into low, intermediate, and high risk of opiate use based on their type of surgery. RESULTS: This study is being funded and supported by the CLHSS Rapid Prospective Evaluation and Digital Technology Innovation Programs, and M Health Fairview. Support and coordination provided by CLHSS include the structure of engagement, survey development, data collection, statistical analysis, and dissemination. The project was initially started in August 2022. The pilot was launched in February 2023 and is still running, with the data last counted in August 2023. The actual RCT is planned to start by early 2024. CONCLUSIONS: Through this RCT, we will test our hypothesis that patient opioid use and diverted prescription opioid availability can both be improved by information delivery applied through a behavioral economics lens via sending nudges directly to the opioid users through their personal health record. TRIAL REGISTRATION: ClinicalTrials.gov NCT06124079; https://clinicaltrials.gov/study/NCT06124079. INTERNATIONAL REGISTERED REPORT IDENTIFIER (IRRID): PRR1-10.2196/52882.
RÉSUMÉ
We describe the development and usability evaluation of a novel patient engagement tool (OPY) in its early stage from perspectives of both experts and end-users. The tool is aimed at engaging patients in positive behaviors surrounding the use, weaning, and disposal of opioid medications in the post-surgical setting. The messaging and design of the application were created through a behavioral economics lens. Expert-based heuristic analysis and user testing were conducted and demonstrated that while patients found the tool to be easy to use and subjectively somewhat useful, additional work to enhance the user interface and features is needed in close partnership with developers and stakeholders.

Opioid overdose deaths have dramatically increased by 781% from 1999 to 2021. In the setting of HIV, opioid drug abuse exacerbates neurotoxic effects of HIV in the brain, as opioids enhance viral replication, promote neuronal dysfunction and injury, and dysregulate an already compromised inflammatory response. Despite the rise in fentanyl abuse and the close association between opioid abuse and HIV infection, the interactive comorbidity between fentanyl abuse and HIV has yet to be examined in vivo. The HIV-1 Tat-transgenic mouse model was used to understand the interactive effects between fentanyl and HIV. Tat is an essential protein produced during HIV that drives the transcription of new virions and exerts neurotoxic effects within the brain. The Tat-transgenic mouse model uses a glial fibrillary acidic protein (GFAP)-driven tetracycline promoter which limits Tat production to the brain and this model is well used for examining mechanisms related to neuroHIV. After 7 days of fentanyl exposure, brains were harvested. Tight junction proteins, the vascular cell adhesion molecule, and platelet-derived growth factor receptor-ß were measured to examine the integrity of the blood brain barrier. The immune response was assessed using a mouse-specific multiplex chemokine assay. For the first time in vivo, we demonstrate that fentanyl by itself can severely disrupt the blood-brain barrier and dysregulate the immune response. In addition, we reveal associations between inflammatory markers and tight junction proteins at the blood-brain barrier.

BACKGROUND: Inadvertent intra-arterial injection of illicit substances is a known complication of injection drug use and can lead to severe complications, including infection, ischemia and compartment syndrome. Identifying complications of intra-arterial injection can be difficult, as clinical manifestations overlap with other more common conditions such as cellulitis and soft tissue infection, and a history of injection drug use is frequently not disclosed. METHODS: A 37-year-old male patient presented with 24 hours of right hand pain, erythema and swelling. Despite classic "track marks", he denied a history of injection drug use, and vascular insults were not initially considered. After failing to respond to three days of aggressive treatment for suspected deep-space infection, an arteriogram demonstrated findings consistent with digital ischemia of embolic etiology. RESULTS: As a result of the delay in diagnosis, the lesion was not amenable to reperfusion and the patient required amputation of the distal digit. CONCLUSION: Practitioners should be alert to the possibility of intra-arterial injection and resulting complications when evaluating unusual extremity infections or unexplained ischemic symptoms, even in the absence of a definite history of injection drug use.
