BACKGROUND
Benzodiazepine-involved overdose deaths are rising, driven by increasing use of nonprescribed benzodiazepine pills. For patients who wish to stop nonprescribed benzodiazepine use, rapid inpatient tapers are typically the only option to treat benzodiazepine withdrawal. Substance use disorder bridge clinics can provide the high-touch care needed to manage outpatient benzodiazepine tapers in patients at high risk due to other substance use disorders.
OBJECTIVE
Describe the implementation and short-term outcomes of an outpatient benzodiazepine taper protocol to treat benzodiazepine withdrawal in a substance use disorder bridge clinic.
METHODS
The clinical team developed a 4- to 6-week intensive outpatient taper protocol using diazepam. Patients with benzodiazepine use disorder were eligible if they had benzodiazepine withdrawal, lacked a prescriber, wanted to stop benzodiazepines completely, and agreed to daily visits. For patients who initiated a taper between April 2021 and December 2022, we evaluated the proportion of patients who completed a taper (i.e., tapered to a last prescribed dose of diazepam 10 mg/d or less); likelihood of remaining on the taper over time; and seizure, overdose, or death documented at the study institution during or within 1 month of taper completion or discontinuation. Other secondary outcomes included HIV testing and prevention, hepatitis C testing, and referrals to recovery coaching or psychiatry.
RESULTS
Fifty-four patients initiated a total of 60 benzodiazepine tapers. The population was mostly male (61%) and non-Hispanic White (85%). Nearly all patients had opioid use disorder (96%), and most (80%) were taking methadone or buprenorphine for opioid use disorder before starting the taper. Patients reported using multiple substances in addition to benzodiazepines, most commonly fentanyl (75%), followed by cocaine (41%) and methamphetamine (21%). Fourteen patients (23%) completed a taper with a median duration of 34 days (IQR 27.8-43.5). Most tapers were stopped when the patient was lost to follow-up (57%), or the team recommended inpatient care (18%). Two patients had a seizure, and 4 had a presumed opioid-involved overdose during or within 1 month after the last taper visit, all individuals who did not complete a taper. No deaths occurred during or within 1 month of taper completion or discontinuation. Challenges included frequent loss to follow-up in the setting of other unstable substance use. Patients received other high-priority care during the taper including HIV testing (32%), PrEP initiation (6.7%), hepatitis C testing (30%), and referrals to recovery coaches (18%) and psychiatry (6.7%).
CONCLUSIONS
Managing benzodiazepine withdrawal with a 4- to 6-week intensive outpatient taper in patients with benzodiazepine and opioid use disorders is challenging. More work is needed to refine patient selection, balance safety risks with feasibility, and study long-term, patient-centered outcomes.

IMPORTANCE
Opioid medications are commonly prescribed for the management of acute postoperative pain. In light of increasing awareness of the potential risks of opioid prescribing, data are needed to define the procedures and populations for which most opioid prescribing occurs.
OBJECTIVE
To identify the surgical procedures accounting for the highest proportion of opioids dispensed to adults after surgery in the United States.
DESIGN, SETTING, AND PARTICIPANTS
This cross-sectional analysis of the 2020-2021 Merative MarketScan Commercial and Multi-State Databases, which capture medical and pharmacy claims for 23 million and 14 million annual privately insured patients and Medicaid beneficiaries, respectively, included surgical procedures for individuals aged 18 to 64 years with a discharge date between December 1, 2020, and November 30, 2021. Procedures were identified using a novel crosswalk between 3664 Current Procedural Terminology codes and 1082 procedure types. Data analysis was conducted from November to December 2023.
MAIN OUTCOMES AND MEASURES
The total amount of opioids dispensed within 3 days of discharge from surgery across all procedures in the sample, as measured in morphine milligram equivalents (MMEs), was calculated. The primary outcome was the proportion of total MMEs attributable to each procedure type, calculated separately among procedures for individuals aged 18 to 44 years and those aged 45 to 64 years.
RESULTS
Among 1 040 934 surgical procedures performed (mean [SD] age of patients, 45.5 [13.3] years; 663 609 [63.7%] female patients), 457 016 (43.9%) occurred among individuals aged 18 to 44 years and 583 918 (56.1%) among individuals aged 45 to 64 years. Opioid prescriptions were dispensed for 503 058 procedures (48.3%). Among individuals aged 18 to 44 years, cesarean delivery accounted for the highest proportion of total MMEs dispensed after surgery (19.4% [11 418 658 of 58 825 364 MMEs]). Among individuals aged 45 to 64 years, 4 of the top 5 procedures were common orthopedic procedures (eg, arthroplasty of knee, 9.7% of total MMEs [5 885 305 of 60 591 564 MMEs]; arthroscopy of knee, 6.5% [3 912 616 MMEs]).
CONCLUSIONS AND RELEVANCE
In this cross-sectional study of the distribution of postoperative opioid prescribing in the United States, a small number of common procedures accounted for a large proportion of MMEs dispensed after surgery. These findings suggest that the optimal design and targeting of surgical opioid stewardship initiatives in adults undergoing surgery should focus on the procedures that account for the most opioid dispensed following surgery over the life span, such as childbirth and orthopedic procedures. Going forward, systems that provide periodic surveillance of opioid prescribing and associated harms can direct quality improvement initiatives to reduce opioid-related morbidity and mortality.

Review
From 2019 to 2020, antihistamines were found in 15% of all US drug overdose deaths, often co-administered with fentanyl, with 3.6% of overdose deaths due to antihistamines alone. The most common antihistamine found in all these reported deaths is diphenhydramine, a ubiquitous, over-the-counter and clinically important medication. Currently, there is no antidote for diphenhydramine overdose. This review summarizes the adverse health effects and current emergency medicine treatments for diphenhydramine. Several emergency medicine case reports are reviewed, and the efficacy and outcomes of a variety of treatments are compared. The treatments reviewed include the more traditional antihistamine overdose therapeutics physostigmine and sodium bicarbonate, as well as newer ones such as donepezil, dexmedetomidine, and lipid emulsion therapy. We conclude that more study is needed to determine the ideal therapeutic approach to treating antihistamine overdoses.

Review
The evolution from conventional to modern agricultural practices, characterized by Agriculture 4.0 principles such as the application of innovative materials, smart water, and nutrition management, addresses the present-day challenges of food supply. In this context, polymer hydrogels have become a promising material for enhancing agricultural productivity due to their ability to retain and then release water, which can help alleviate the need for frequent irrigation in dryland environments. Furthermore, the controlled release of fertilizers by the hydrogels decreases chemical overdosing risks and the environmental impact associated with the use of agrochemicals. The potential of polymer hydrogels in sustainable agriculture and farming and their impact on soil quality is revealed by their ability to deliver nutritional and protective active ingredients. Thus, the impact of hydrogels on plant growth, development, and yield was discussed. The question of which hydrogels are more suitable for agriculture-natural or synthetic-is debatable, as both have their merits and drawbacks. An analysis of polymer hydrogel life cycles in terms of their initial material has shown the advantage of bio-based hydrogels, such as cellulose, lignin, starch, alginate, chitosan, and their derivatives and hybrids, aligning with sustainable practices and reducing dependence on non-renewable resources.

BACKGROUND AND OBJECTIVES
Surgery is one of the most common indications for opioid prescribing to pediatric patients. We identified which procedures account for the most pediatric surgical opioid prescribing.
METHODS
We conducted a cross-sectional analysis of commercial and Medicaid claims in the Merative MarketScan Commercial and Multi-State Medicaid Databases. Analyses included surgical procedures for patients aged 0 to 21 years from December 1, 2020, to November 30, 2021. Procedures were identified using a novel crosswalk between 3664 procedure codes and 1082 procedure types. For each procedure type in the crosswalk, we calculated the total amount of opioids in prescriptions dispensed within 3 days of discharge from surgery, as measured in morphine milligram equivalents (MMEs). We then calculated the share of all MMEs accounted for by each procedure type. We conducted analyses separately among patients aged 0 to 11 and 12 to 21 years.
RESULTS
Among 107 597 procedures for patients aged 0 to 11 years, the top 3 procedures accounted for 59.1% of MMEs in opioid prescriptions dispensed after surgery: Tonsillectomy and/or adenoidectomy (50.3%), open treatment of upper extremity fracture (5.3%), and removal of deep implants (3.5%). Among 111 406 procedures for patients aged 12 to 21 years, the top 3 procedures accounted for 33.1% of MMEs: Tonsillectomy and/or adenoidectomy (12.7%), knee arthroscopy (12.6%), and cesarean delivery (7.8%).
CONCLUSIONS
Pediatric surgical opioid prescribing is concentrated among a small number of procedures. Targeting these procedures in opioid stewardship initiatives could help minimize the risks of opioid prescribing while maintaining effective postoperative pain control.

Naloxone, an opioid receptor antagonist, effectively reverses opioid overdose and opioid-induced respiratory depression. A few side effects were reported after naloxone administration, including arrhythmia and pulmonary edema. Although rare, naloxone-induced pulmonary edema can be a severe and sometimes life-threatening complication requiring mechanical ventilation. This condition is predominantly linked to an upsurge in catecholamines after opioid reversal as part of acute withdrawal syndrome, especially seen in patients who chronically use opioids. In this report, we present a case of a 66-year-old patient who developed pulmonary edema following the administration of multiple doses of intravenous and intranasal naloxone for opioid overdose. This case highlights the potential adverse effects associated with naloxone use and discusses how to employ this life-saving medication with minimal side effects.

AIMS
This study sought to develop and assess an exploratory model of how demographic and psychosocial attributes, and drug use or acquisition behaviors interact to affect opioid-involved overdoses.
DESIGN
We conducted exploratory and confirmatory factor analysis (EFA/CFA) to identify a factor structure for ten drug acquisition and use behaviors. We then evaluated alternative structural equation models incorporating the identified factors, adding demographic and psychosocial attributes as predictors of past-year opioid overdose.
SETTING AND PARTICIPANTS
We used interview data collected for two studies recruiting opioid-misusing participants receiving services from a community-based syringe services program. The first investigated current attitudes toward drug-checking (N = 150). The second was an RCT assessing a telehealth versus in-person medical appointment for opioid use disorder treatment referral (N = 270).
MEASUREMENTS
Demographics included gender, age, race/ethnicity, education, and socioeconomic status. Psychosocial measures were homelessness, psychological distress, and trauma. Self-reported drug-related risk behaviors included using alone, having a new supplier, using opioids with benzodiazepines/alcohol, and preferring fentanyl. Past-year opioid-involved overdoses were dichotomized into experiencing none or any.
FINDINGS
The EFA/CFA revealed a two-factor structure with one factor reflecting drug acquisition and the second drug use behaviors. The selected model (CFI = .984, TLI = .981, RMSEA = .024) accounted for 13.1% of overdose probability variance. A latent variable representing psychosocial attributes was indirectly associated with an increase in past-year overdose probability (β = .234, p = .001), as mediated by the EFA/CFA identified latent variables: drug acquisition (β = .683, p < .001) and drug use (β = .567, p = .001). Drug use behaviors (β = .287, p = .04) but not drug acquisition (β = .105, p = .461) also had a significant, positive direct effect on past-year overdose. No demographic attributes were significant direct or indirect overdose predictors.
CONCLUSIONS
Psychosocial attributes, particularly homelessness, increase the probability of an overdose through associations with risky drug acquisition and drug-using behaviors. Further research is needed to replicate these findings with populations at high-risk of an opioid-related overdose to assess generalizability and refine the metrics used to assess psychosocial characteristics.

The toxicologist ascertains drug assumptions in case of paediatric intoxications and death for overdose. The analytical approach consists of initially screening and consequently confirming drug positivity. We developed a toxicological screening method and validated its use comparing the results with a LC-MS/MS analysis. The method identifies 751 drugs and metabolites (704 in positive and 47 in negative mode). Chromatographic separation was achieved eluting mobile phase A (10 mM ammonium formate) and B (0.05% formic acid in methanol) in gradient on Kinetex Phenyl-Hexyl (50 × 4.6 mm, 2.6 μm) with 0.7 mL/min flow rate for 11 min. Multiple Reaction Monitoring (MRM) was adopted as survey scan and, after an Information-Dependent Analysis (IDA) (threshold of 30,000 for positive and 1000 cps for negative mode), the Enhanced Product Ion (scan range: 50-700 amu) was triggered. The MS/MS spectrum generated was compared with one of the libraries for identification. Data processing was optimised through creation of rules. Sample preparation, mainly consisting of deproteinization and enzymatic hydrolysis, was set up for different matrices (blood, urine, vitreous humor, synovial fluid, cadaveric tissues and larvae). Cut-off for most analytes resulted in the lowest concentration tested. When the results from the screening and LC-MS/MS analysis were compared, an optimal percentage of agreement (100%) was assessed for all matrices. Method applicability was evaluated on real paediatric intoxications and forensic cases. In conclusion, we proposed a multi-targeted, fast, sensitive and specific MRM-IDA-EPI screening having an extensive use in different toxicological fields.

Risk of drug-related death associated with co-prescribing of gabapentinoids and Z-drugs among people receiving opioid-agonist treatment: A national retrospective cohort study.
BACKGROUND
Prescribing of gabapentinoids and Z-drug-hypnotics has increased in the population and among people receiving opioid-agonist treatment (OAT) for opioid dependence. Evidence is mixed on whether co-prescribing of sedatives such as gabapentinoids and Z-drugs during OAT increases risk of drug-related death (DRD).
METHODS
We conducted a retrospective cohort study of individuals prescribed OAT between 2011 and 2020 in Scotland. Prescribing records were linked to mortality data and other healthcare datasets (sociodemographic, comorbidity). We identified episodes of treatment with gabapentinoids/Z-drugs and used multivariable quasi-Poisson regression to model associations between co-prescription and DRD risk.
RESULTS
Among 46,602 individuals with 304,783 person-years of follow-up, we found that co-prescription was common, with 25 % and 34 % ever being co-prescribed gabapentinoids and Z-drugs, respectively. Gabapentinoid exposure was strongly associated (adjusted hazard ratio (aHR)=2·18, 95 % CI=1·92, 2·46) and Z-drug exposure moderately associated (aHR=1·39, 95 % CI=1·15, 1·66) with elevated risk of DRD. Gabapentinoid exposure was associated with DRD risk on and off OAT; Z-drug exposure was less strongly associated with DRD risk when on OAT.
CONCLUSIONS
Co-prescription of gabapentinoids and Z-drugs is common among OAT patients. However, co-prescription is associated with increased risk of DRD. Alternatives to prescribing sedative medications to OAT patients and/or greater monitoring - if prescribed - are needed.

Missouri's Overdose Field Report (ODFR) is a community-based reporting system which intends to capture overdoses which may not be otherwise recorded. Describe the factors related to non-fatal overdoses reported to Missouri's ODFR. This study used a descriptive epidemiological approach to examine the demographics and circumstances of overdoses reported to the ODFR. We used binary logistic regression to evaluate factors associated with survival and ordinal logistic regression to evaluate factors associated with number of doses used. Factors were chosen based on their relevance to overdose education and survival, and naloxone distribution. Between 2018 and 2022, 12,225 overdoses (67% male; 78% White) were reported through the ODFR, with a 96% (n = 11,225) survival rate. Overdose survival (ps < .02) was associated with younger age (OR = .58), no opioid and stimulant co-involvement (OR = .61), and private location (OR = .48). Intramuscular naloxone in particular was associated with a significantly higher odds of survival compared to nasal naloxone (OR = 2.11). An average of 1.6 doses of naloxone per incident were administered. Additional doses were associated (ps < .02) with being older (OR = .45), female (OR = .90), nasal naloxone (versus intravenous) (OR = .65), and the belief fentanyl was present (OR = 1.49). Our reporting form provides a comprehensive picture of the events surrounding reported overdoses, including factors associated with survival, how much naloxone was used, and the effects of respondents believing fentanyl was involved. Missouri's report can provide support for current naloxone dosing, contextualize refusing post-overdose transport, and can be used to improve overdose response by community and first responders.
