RESUMEN

The influence of genetic variants related to opioid use disorder (OUD) was evaluated using multiple logistic regression analysis in self-reported assigned African American/Afro-Caribbean and European biogeographical ancestry groups (BGAGs) and by sex. From a sample size of 1301 adult patients (>18 years of age) seen in emergency departments of three medical centers in Ohio, six variants were found to be associated with OUD. Two of the variants, rs2740574 (CYP3A4) and rs324029 (DRD3), were included in the analysis having met criteria of at least five subjects for each BGAG, variant carrier status, and OUD status combinations. Variant carriers in the African/Afro-Caribbean BGAG had slightly lower predicted probabilities of OUD. Variant carriers in the European BGAG had slightly higher predicted probabilities of OUD. Relative to sex, all the six variants met evaluation criteria (five subjects for all sex, variant, and OUD status combinations). No statistically significant interactions were found between a given variant, BGAGs and sex. Findings suggest variant testing relative to OUD risk can be applied across BGAGs and sex, however, studies in larger populations are needed.

RESUMEN

Carbon monoxide (CO) exposure is a prevalent cause of poisoning worldwide. The cardiac effects of CO poisoning are well described and can manifest as angina, myocardial ischemia or infarction, cardiogenic shock, and/or life-threatening arrhythmias. Atrial fibrillation has been associated with severe CO poisoning; however, few cases have described atrial fibrillation in acute CO poisoning with regard to hyperbaric oxygen (HBO2) therapy. Herein, we describe a case of severe CO poisoning that caused atrial fibrillation with successful conversion to sinus rhythm following HBO2 therapy and discuss implications for further research.

RESUMEN

Study objective: Earlier intervention for opioid use disorder (OUD) may reduce long-term health implications. Emergency departments (EDs) in the United States treat millions with OUD annually who may not seek care elsewhere. Our objectives were (1) to compare two screening measures for OUD characterization in the ED and (2) to determine the proportion of ED patients screening positive for OUD and those who endorse other substance use to guide future screening programs. Methods: A cross-sectional study of randomly selected adult patients presenting to three Midwestern US EDs were enrolled, with duplicate patients excluded. Surveys were administered via research assistant and documented on tablet devices. Demographics were self-reported, and OUD positivity was assessed by the DSM 5 checklist and the WHO ASSIST 3.1. The primary outcome was the concordance between two screening measures for OUD. Our secondary outcome was the proportion of ED patients meeting OUD criteria and endorsed co-occurring substance use disorder (SUD) criteria. Results: We enrolled 1305 participants; median age of participants was 46 years (range 18-84), with 639 (49.0%) Non-Hispanic, White, and 693 (53.1%) female. Current OUD positivity was identified in 17% (222 out of 1305) of the participants via either DSM-5 (two or more criteria) or ASSIST (score of 4 or greater). We found moderate agreement between the measures (kappa = 0.56; Phi coefficient = 0.57). Of individuals screening positive for OUD, 182 (82%) endorsed criteria for co-occurring SUD. Conclusions: OUD is remarkably prevalent in ED populations, with one in six ED patients screening positive. We found a high prevalence of persons identified with OUD and co-occurring SUD, with moderate agreement between measures. Developing and implementing clinically feasible OUD screening in the ED is essential to enable intervention.

RESUMEN

Genetics are presumed to contribute 30-40% to opioid use disorder (OUD), allowing for the possibility that genetic markers could be used to identify personal risk for developing OUD. We aimed to test the potential association among 180 candidate single nucleotide polymorphisms (SNPs), 120 of which were related to the dopamine reward pathway and 60 related to pharmacokinetics. Participants were randomly recruited in 2020-2021 in a cross-sectional genetic association study. Self-reported health history including Diagnostic and Statistical Manual of Mental Disorders (DSM-5) OUD criteria and buccal swabs were collected. A total of 1,301 participants were included in the analyses for this study. Of included participants, 250 met the DSM-5 criteria for ever having OUD. Logistic regression, adjusting for age and biologic sex, was used to characterize the association between each SNP and DSM-5 criteria consistent with OUD. Six SNPs found in four genes were associated with OUD: increased odds with CYP3A5 (rs15524 and rs776746) and DRD3 (rs324029 and rs2654754), and decreased odds with CYP3A4 (rs2740574) and CYP1A2 (rs2069514). Homozygotic CYP3A5 (rs15524 and rs776746) had the highest adjusted odds ratio of 2.812 (95% confidence interval (CI) 1.737, 4.798) and 2.495 (95% CI 1.670, 3.835), respectively. Variants within the dopamine reward and opioid metabolism pathways have significant positive (DRD3 and CYP3A5) and negative (CYP3A4 and CYP1A2) associations with OUD. Identification of these variants provides promising possibilities for genetic prognostic and therapeutic targets for future investigation.

RESUMEN

INTRODUCTION: In disaster response, smartphone applications (or apps) are being used by the layperson, emergency first responders, and health care providers to aid in everything from incident reporting to clinical decision making. However, quality apps are often diluted by the overwhelming number of apps that exist for both the lay public and first responders in the Apple iTunes (Apple Inc.; Cupertino, California USA) and Google Play (Google LLC; Mountain View, California USA) stores. HYPOTHESIS/PROBLEM: A systematic review of disaster response apps was originally completed in 2015; a follow-up review was completed here to evaluate trends and explore novel apps. METHODS: A search of the Apple iTunes and Google Play stores was performed using the following terms obtained from PubMed (National Center for Biotechnology Information; Bethesda, Maryland USA) Medical Subject Headings Database: Emergency Preparedness; Emergency Responders; Disaster; Disaster Planning; Disaster Medicine; Bioterrorism; Chemical Terrorism; Hazardous Materials; and the Federal Emergency Management Agency (FEMA [Washington, DC USA]). After excluding any unrelated apps, a working list of apps was formed and categorized based on topics. Apps were categorized by intended user (first responders or the public) and sub-categorized by topic for discussion. Sub-categories included News/Information, Reference/Education, Weather/Natural Disasters, Travel/Navigation, and Communication/Reunification. RESULTS: A search of the Apple iTunes store revealed 394 unique apps and was narrowed to 342 based on relevance to the field and availability on the iPhone. A search of the Google Play store yielded 645 unique applications and was narrowed to 634 based on relevance. Of note, 49 apps appeared in both app stores using the search terms. An aggregate 927 apps from the Apple iTunes and Google Play stores were then critically reviewed by the authors. Apps were sub-categorized based on intended audience, layperson or first responder, and sorted into one of five disaster response categories. Two apps were chosen for discussion from each of the five sub-categories. The highest quality apps were determined from each group based on relevance to emergency preparedness and disaster response, rating, and number of reviews. CONCLUSION: After comparisons with the 2015 article, many new apps have been developed and previously described apps have been updated, highlighting that this is a constantly changing field deserving of continued analysis and research.

RESUMEN

(1) Background: COVID-19 vaccination status varies widely among law enforcement and emergency medical services professionals. Though at high risk of exposure, these first responders have demonstrated significant vaccine hesitancy, with only 70% reportedly vaccinated. We sought to understand whether similar vaccine hesitancy exists for first responders and their household contacts around COVID-19 boosters. (2) Methods: In a prospective longitudinal cohort of first responders and their household contacts, survey data was collected, including demographics, medical history, COVID-19 exposure risks, and vaccination and/or booster status. The statistical analysis focused on primary vaccination and booster rates of both the first responders and their household contacts. (3) Results: Across 119 study participants, 73% reported having received some combination of vaccine and/or booster, and 26% were unvaccinated. Vaccinated individuals were older, reported less prior exposure to COVID-19 and had more comorbidities. Only 23% reported having received a COVID-19 booster. Pairing of the data for household contacts demonstrated a 60% agreement to receive primary vaccination but only a 20% agreement for boosters within households. (4) Conclusions: This study provides insight into the vaccination and booster rates of first responders and household contacts. Focused efforts to enhance vaccinations is essential for the protection and maintenance of this critical workforce.

RESUMEN

BACKGROUND: Over time, Residency Match dynamics fluctuate with some specialties experiencing increases in medical student popularity. Academic departments with limited resources must devise methods for coping with increased demand for their specialty. Students perceive traditional programs on Match mechanics as inadequate. Subsequently, faculty are confronted with demands for more personal attention from more students. OBJECTIVES: We developed a strategy for providing specialty-specific residency match advising to large numbers of students. METHODS: The 'speed-advising' session (SAS) was developed to address the common questions and concerns that medical students pose during the Match process and to provide advisees with a breadth of faculty perspectives. Two SASs were offered over a 2-week period. After the sessions, students and faculty were surveyed regarding their experience. RESULTS: Twenty-six students pursued our specialty in the 2015 Match (26 of 234, 11.1%). Twenty-three (89%) participated in the SAS. Seventy-four percent of students (17 of 23) and all faculty completed the post-session survey. Students found the SAS to be informative, helpful and an efficient use of time. Common discussion topics included: career goals, to which programs and how many to apply, and how academic record impacts their likelihood of matching in our specialty. Students would have preferred more time with each faculty; however, most (77%) conceded that their questions were adequately answered. Faculty-favored speed advising over traditional advising (86%), primarily due to estimated time savings of 7.3 h per faculty member. CONCLUSIONS: In preparing students for the Match, specialty-specific speed advising offers an efficient supplement to traditional advising.

RESUMEN

INTRODUCTION: Smartphone applications (or apps) are becoming increasingly popular with emergency responders and health care providers, as well as the public as a whole. There are thousands of medical apps available for Smartphones and tablet computers, with more added each day. These include apps to view textbooks, guidelines, medication databases, medical calculators, and radiology images. Hypothesis/Problem With an ever expanding catalog of apps that relate to disaster medicine, it is hard for both the lay public and responders to know where to turn for effective Smartphone apps. A systematic review of these apps was conducted. METHODS: A search of the Apple iTunes store (Version 12; Apple Inc.; Cupertino, California USA) was performed using the following terms obtained from the PubMed Medical Subject Headings Database: Emergency Preparedness, Emergency Responders, Disaster, Disaster Planning, Disaster Medicine, Bioterrorism, Chemical Terrorism, Hazardous Materials (HazMat), and the Federal Emergency Management Agency (FEMA). After excluding any unrelated apps, a working list of apps was formed and categorized based on topics. Apps were grouped based on applicability to responders, the lay public, or regional preparedness, and were then ranked based on iTunes user reviews, value, relevance to audience, and user interface. RESULTS: This search revealed 683 applications and was narrowed to 219 based on relevance to the field. After grouping the apps as described above, and subsequently ranking them, the highest quality apps were determined from each group. The Community Emergency Response Teams and FEMA had the best apps for National Disaster Medical System responders. The Centers for Disease Control and Prevention (CDC) had high-quality apps for emergency responders in a variety of fields. The National Library of Medicine's Wireless Information System for Emergency Responders (WISER) app was an excellent app for HazMat responders. The American Red Cross had the most useful apps for natural disasters. Numerous valuable apps for public use, including alert apps, educational apps, and a well-made regional app, were also identified. CONCLUSION: Smartphone applications are fast becoming essential to emergency responders and the lay public. Many high-quality apps existing in various price ranges and serving different populations were identified. This field is changing rapidly and it deserves continued analysis as more apps are developed.

RESUMEN

OBJECTIVE: Contemporary disasters, like the outbreak of Ebola in West Africa, have piqued the interest of medical students in disaster preparedness. The topic is also a requirement of undergraduate medical education.(1) Yet current literature suggests that disaster preparedness education is lacking. Our objective was to pilot a curriculum to augment medical students' disaster preparedness education by marshalling local resources to provide practical hands-on experiences. DESIGN: This pilot curriculum consisted of lectures; simulations; asynchronous learning materials; a large-scale, regional disaster exercise; and preparation for and participation in a real-time mass gathering. Outcomes were measured by student performance on written tests and evaluations of each activity. SETTING: Academic Health Center with associated medical school. PARTICIPANTS: Fifty-two medical students participated in at least one of the six activities during this voluntary pilot program. Premedical students and residents (n=57) participated in some activities. RESULTS: Forty-one medical students took either the pretest or the post-test over the curriculum. Only eight students took both. A paired t test comparing pretest to post-test scores using imputed missing data (t=-11.72, df=40, p≤0.001) was consistent with an analysis using only complete data (t=-2.35, df=7, p=0.05), implying that student scores improved significantly over time. Evaluations indicated a student preference for hands-on over didactic or independent learning activities. CONCLUSIONS: This pilot curriculum was designed to capitalize on practical hands-on training opportunities for our medical students, including participation in a disaster exercise and a mass-gathering event. These opportunities provided effective and engaging disaster preparedness education.

RESUMEN

Since the terrorist attacks and anthrax release in 2001, almost $32 billion has been allocated to biodefense and biosurveillance in the USA alone. Surveillance in health care refers to the continual systematic collection, analysis, interpretation, and dissemination of data. When attempting to detect agents of bioterrorism, surveillance can occur in several ways. Syndromic surveillance occurs by monitoring clinical manifestations of certain illnesses. Laboratory surveillance occurs by looking for certain markers or laboratory data, and environmental surveillance is the process by which the ambient air or environment is continually sampled for the presence of biological agents. This paper focuses on the ways by which we detect bioterrorism agents and the effectiveness of these systems.
