OBJECTIVE
The authors sought to explore the role of iron supplementation in the management of neurodevelopmental disorders among children and youths.
METHODS
A systematic review in accordance with Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines was undertaken. A subset of results was suitable for meta-analysis. The quality of the evidence and strength of the clinical recommendations were assessed by using the Grading of Recommendations, Assessment, Development, and Evaluation method, and critical appraisal was conducted with the Joanna Briggs Institute critical appraisal tools.
RESULTS
Nine articles met inclusion criteria. These articles included studies of attention-deficit hyperactivity disorder (ADHD) (N=7), autism spectrum disorder (N=1), and Tourette's syndrome (N=1). Three randomized controlled trials evaluating iron supplementation for ADHD hyperactivity symptom severity (124 participants: placebo, N=56; supplement, N=68) met inclusion criteria for a meta-analysis. Effect sizes for the placebo and supplement groups were moderate (Cohen's d=0.76) and large (Cohen's d=1.70), respectively, although these differences were not significant. The impact of iron supplementation on inattentive ADHD symptom severity was examined in two trials (75 participants: placebo, N=31; supplement, N=44). Large, nonsignificant effect sizes were demonstrated for the placebo (Cohen's d=1.66) and supplementation (Cohen's d=3.19) groups. The quality of the evidence and strength of the clinical recommendations were considered very low.
CONCLUSIONS
Further research is needed to examine the role of iron supplementation in the management of ADHD and neurodevelopmental disorders more generally. Additionally, iron supplementation comes with risks, including death in the case of overdose.

Extracorporeal membrane oxygenation (ECMO) has had increasing prevalence and indications in the last decade. Calcium channel blocker overdose (CCBOD) can lead to significant cardiopulmonary dysfunction and has also increased in recent years. CCBOD results in cardiac depression, vasoplegia, and hyperglycemia. Expert consensus recommends treatment with calcium, high-dose insulin, inotropes, and vasopressors. Our systematic review evaluated when to initiate ECMO in the CCBOD population and the mortality rate associated with use. Electronic literature review identified all relevant studies for CCBOD and ECMO. PRISMA guidelines for systematic review were followed. Three independent authors reviewed abstracts and full texts, and only CCB ingestion without polypharmacy was included. Two authors independently collected data, which included demographics, current medical treatments, ECMO type, and survival. From 314 abstracts, 25 papers were included with a median publication year of 2019. Twenty-six patients were included with an average age of 32.7 years and 42%/58% male/female. Average time on ECMO 4.3 days. VA and VV ECMO use were 92.3% and 7.7%, respectively, and 84.6% of patients survived to hospital discharge. Before ECMO, most patients received 4-5 medical treatments (53.8%). Our systematic review demonstrates ECMO is a newly used, yet valuable therapy for CCBOD when medical treatment fails. Survival to discharge after ECMO for CCBOD is substantially higher than standard VV or VA ECMO. Medical management is still the mainstay therapy for CCBOD, but we show that a persistently unstable patient may benefit from prompt evaluation at an ECMO center for treatment.

Review
This systematic literature review aims to determine the optimal initial dose of naloxone for successful opioid overdose reversal across different administration routes. Types of participants included adults who have opioid overdoses and adults who are suspected to have opioid overdoses. Pregnant women, children, animals, and populations outside the US were excluded. The interventions included were intranasal (IN), intramuscular (IM), and intravenous (IV) naloxone administration. The data collected for this systematic review were studies from PubMed, CINAHL, PsyINFO, and Cochrane Central Register of Controlled Trials registers between January 2015 and July 2021. The risk of bias was assessed via the Review Manager application. Six studies met the inclusion criteria. A meaningful statistical analysis was unable to be conducted with such few studies. The studies reveal 2 mg IN as the most popular dosing for initial naloxone for successful opioid reversal. The most common route of naloxone administration for successful reversal could not be studied but most studies revealed successful initial naloxone dosing in IN equivalents. With minimal studies emerging from our review, further research is warranted in naloxone dosing for optimal opioid reversal in order to fully treat patients. Healthcare workers must be vigilant of potential withdrawal from high naloxone dosing as well as the inefficiency of lower naloxone dosing for adequate opioid overdose reversal in order to treat patients with opioid overdoses properly.

Review
CONTEXT
Obesity prevalence is persistently increasing worldwide. Among surgical therapeutic procedures, bypass surgery and sleeve gastrectomy have shown the best results regarding weight loss, prevention, and treatment of secondary complications. However, these surgeries are associated with an increased risk of malabsorption and metabolic changes that could further affect the pharmacokinetics of drugs. On the other hand, patients with a history of such surgeries are more likely to experience pain and request analgesic initiation or adaptation. The question of how to manage pain medication in these patients is challenging due to their narrow therapeutic indexes.
OBJECTIVES
To summarize the current literature on the impact of bariatric surgery on the subsequent pharmacokinetics of analgesics and propose a multidisciplinary therapeutic attitude to optimize pain management in these patients.
METHODS
We conducted a systematic review that included all pharmacological studies published after 2000.
RESULTS
Unexpectedly, these surgeries seem to increase the bioavailability of drugs by long-term improvement of hepatic function. Yet, the medical community drastically lacks robust guidelines for pain management in those patients. This systematic review aims to bring together pharmacological studies related to the use of pain treatments in patients who underwent bypass surgery or sleeve gastrectomy.
CONCLUSIONS
Caution should be exercised regarding the risk of overdose in every circumstance: treatment initiation, change of doses, or change of molecule. More prospective trials comparing the pharmacokinetics of medications in obese patients with and without prior bariatric surgery are needed.

Meta-Analysis
Drug use before or during sex is a high-risk sexual behavior associated with adverse health risks and outcomes, such as increasing the likelihood of overdoses and of acquiring sexually-transmitted diseases. This systematic review and meta-analysis of three scientific databases examined the prevalence of the use of intoxicating substances, those tending to excite or stupefy the user on a psychoactive level, before or during sex, among young adults (18-29 years old). A total of 55 unique empirical studies met the inclusion criteria (48,145 individuals; 39% males), were assessed for risk of bias using the tools of Hoy et al. (2012), and were analyzed via a generalized linear mixed-effects model. The results produced a global mean prevalence of this sexual risk behavior of 36.98% (95% CI: 28.28%, 46.63%). Nonetheless, significant differences were identified between different intoxicating substances, with the use of alcohol (35.10%; 95% CI: 27.68%, 43.31%), marijuana (27.80%; 95% CI: 18.24%, 39.92%), and ecstasy (20.90%; 95% CI: 14.34%, 29.45%) significantly more prevalent than that of cocaine (4.32%; 95% CI: 3.64%, 5.11%), heroin (.67%; 95% CI: .09%, 4.65%), methamphetamine (7.10%; 95% CI: 4.57%, 10.88%), and GHB (6.55%; 95% CI: 4.21%, 10.05%). Moderator analyses showed that the prevalence of alcohol use before or during sex differed according to geographical sample origin, and increased as the proportion of ethnic whites in samples increased. The remaining demographic (e.g., gender, age, reference population), sexual (e.g., sexual orientation, sexual activity), health (e.g., drug consumption, STI/STD status), methodological (e.g., sampling technique), and measurement (e.g., timeframe) variables that were examined did not moderate prevalence estimates. Implications for sexual development interventions were discussed.

BACKGROUND
Public health policy researchers face a persistent challenge in identifying and integrating relevant data, particularly in the context of the U.S. opioid crisis, where a comprehensive approach is crucial.
PURPOSE
To meet this new workforce demand health policy and health economics programs are increasingly introducing data analysis and data visualization skills. Such skills facilitate data integration and discovery by linking multiple resources. Common linking strategies include individual or aggregate level linking (e.g., patient identifiers) in primary clinical data and conceptual linking (e.g., healthcare workforce, state funding, burnout rates) in secondary data. Often, the combination of primary and secondary datasets is sought, requiring additional skills, for example, understanding metadata and constructing interlinkages.
METHODS
To help improve those skills, we developed a 2-step process using a scoping method to discover data and network visualization to interlink metadata. Results: We show how these new skills enable the discovery of relationships among data sources pertinent to public policy research related to the opioid overdose crisis and facilitate inquiry across heterogeneous data resources. In addition, our interactive network visualization introduces (1) a conceptual approach, drawing from recent systematic review studies and linked by the publications, and (2) an aggregate approach, constructed using publicly available datasets and linked through crosswalks.
CONCLUSIONS
These novel metadata visualization techniques can be used as a teaching tool or a discovery method and can also be extended to other public policy domains.

INTRODUCTION
Acetaminophen poisoning is commonly treated by emergency physicians. First-line therapy is N-acetylcysteine (NAC), traditionally administered intravenously via a US Food and Drug Administration (FDA)-approved three-bag protocol in which each bag has a unique concentration and infusion duration. Recently, simplified, off-label two-bag NAC infusion protocols have become more common. The purpose of this review is to summarize the effectiveness and safety of two-bag NAC.
METHODS
We undertook a comprehensive search of PubMed, EMBASE, and MEDLINE from inception to December 13, 2022, for articles describing human acetaminophen poisonings treated with two-bag NAC, defined as any regimen involving two discrete infusions in two separate bags. Outcomes included effectiveness (measured by incidence of liver injury); incidence of non-allergic anaphylactoid reactions (NAAR); gastrointestinal, cutaneous, and systemic reactions; treatments for NAARs; incidence of NAC-related medication errors; and delays or interruptions in NAC administration.
RESULTS
Twelve articles met final inclusion, 10 of which compared two-bag NAC to the three-bag regimen. Nine articles evaluated the two-bag/20-hour regimen, a simplified version of the FDA-approved three-bag regimen in which the traditional first and second bags are combined into a single four-hour infusion. Nine articles assessed comparative effectiveness of two-bag NAC in terms of liver injury, most commonly assessed for by incidence of hepatotoxicity (aspartate aminotransferase or alanine aminotransferase >1,000 international units per liter). No difference in liver injury was observed between two-bag and three-bag regimens. Of nine articles comparing incidence of NAARs, eight demonstrated statistically fewer NAARs with two-bag regimens, and one showed no difference. In seven articles evaluating treatment for NAARs (antihistamines, corticosteroids, epinephrine), all showed that patients received fewer medications for NAARs with two-bag NAC. Three articles evaluated NAC-related medication errors; two demonstrated no difference, while one study evaluating only children showed fewer errors with two-bag NAC. Two studies evaluated delays and/or interruptions in NAC infusions; both favored two-bag NAC.
CONCLUSION
For patients with acetaminophen poisoning, two-bag NAC regimens appear to have similar outcomes to the traditional three-bag regimen in terms of liver injury. Two-bag NAC regimens are associated with fewer adverse events and fewer treatments for those events than the three-bag regimen and fewer interruptions in antidotal therapy.

Journal of American College Health : J... Jan 2024To identify and describe interventions that increase access to naloxone for undergraduate students.
OBJECTIVE
To identify and describe interventions that increase access to naloxone for undergraduate students.
METHODS
A systematic review across 4 databases identified interventions that expand access to naloxone at colleges in the United States from 2015-2023. Three reviewers extracted the following data to create a narrative synthesis and summary of program elements: setting, rationale for intervention, timeline, intervention components, study size, collaboration, sustainability, outcomes and results.
RESULTS
Seven articles met inclusion criteria. Institutions' implemented naloxone interventions due to concerns for student safety and/or student overdose fatalities. Three universities collaborated with their School of Pharmacy for program design and/or dissemination, while two partnered with state-based naloxone distribution programs. Most programs combined opioid-overdose/naloxone training; four distributed naloxone kits. Three studies included pre/post-outcomes, and all reported increases in participant knowledge, attitudes, and/or ability to respond to an overdose.
CONCLUSIONS
Our results indicates an opportunity for wide-scale implementation of undergraduate naloxone programs within US colleges. However, more rigorous implementation research is needed to identify barriers and facilitators to program feasibility, acceptability, and participation.
