A Comparison Of Standardized Letters Of Evaluation For Emergency Medicine Residency Applicants., David Wilson, Chaiya Laoteppitaks, Shruti Chandra

Department of Emergency Medicine Faculty Papers

INTRODUCTION: Medical students pursuing an emergency medicine (EM) residency are advised to obtain at least two Standardized Letters of Evaluation (SLOE). Students often complete one rotation at their home institution and at least one "away" rotation at a program separate from their home institution. The SLOE was introduced as an objective evaluation tool. The aim of this study was to determine whether there was a difference in scores between home rotation and away rotation SLOEs.

METHODS: We retrospectively reviewed the SLOEs of all applicants to an urban, academic EM residency program. For each SLOE, we calculated a composite score from …

Mir15a/Mir16-1 Cluster And Its Novel Targeting Molecules Negatively Regulate Cardiac Hypertrophy., Hongchang Guo, Ke Ma, Wenjing Hao, Yao Jiao, Ping Li, Jing Chen, Chen Xu, Fu-Jian Xu, Wayne Bond Lau, Jie Du, Xin-Liang Ma, Yulin Li

Department of Emergency Medicine Faculty Papers

In response to pathological stimuli, the heart develops ventricular hypertrophy that progressively decompensates and leads to heart failure. miRNAs are increasingly recognized as pathogenic factors, clinically relevant biomarkers, and potential therapeutic targets. We identified that mir15a/mir16-1 cluster was negatively correlated with hypertrophic severity in patients with hypertrophic cardiomyopathy. The mir15a/mir16-1 expression was enriched in cardiomyocytes (CMs), decreased in hypertrophic human hearts, and decreased in mouse hearts after transverse aortic constriction (TAC). CM-specific mir15a/mir16-1 knockout promoted cardiac hypertrophy and dysfunction after TAC. CCAAT/enhancer binding protein (C/EBP)β was responsible for the downregulation of mir15a/mir16-1 cluster transcription. Mechanistically, mir15a/mir16-1 cluster attenuated the insulin/IGF1 …

Percentages and 95% confidence intervals [CI] were calculated.

RESULTS: One hundred four surveys were completed. Of respondents involved in the interview process, …

The Sensitivity Of Qsofa Calculated At Triage And During Emergency Department Treatment To Rapidly Identify Sepsis Patients., Sarah M. Perman, Mark E. Mikkelsen, Munish Goyal, Adit Ginde, Abhishek Bhardwaj, Byron Drumheller, S. Cham Sante, Anish K. Agarwal, David F. Gaieski

Department of Emergency Medicine Faculty Papers

The quick sequential organ failure assessment (qSOFA) score has been proposed as a means to rapidly identify adult patients with suspected infection, in pre-hospital, Emergency Department (ED), or general hospital ward locations, who are in a high-risk category with increased likelihood of "poor outcomes:" a greater than 10% chance of dying or an increased likelihood of spending 3 or more days in the ICU. This score is intended to replace the use of systemic inflammatory response syndrome (SIRS) criteria as a screening tool; however, its role in ED screening and identification has yet to be fully elucidated. In this retrospective …

Inpatient Hospital Performance Is Associated With Post-Discharge Sepsis Mortality., Nicholas M. Mohr, Alexis M. Zebrowski, David F. Gaieski, David G. Buckler, Brendan G. Carr

Department of Emergency Medicine Faculty Papers

BACKGROUND: Post-discharge deaths are common in patients hospitalized for sepsis, but the drivers of post-discharge deaths are unclear. The objective of this study was to test the hypothesis that hospitals with high risk-adjusted inpatient sepsis mortality also have high post-discharge mortality, readmissions, and discharge to nursing homes.

METHODS: Retrospective cohort study of age-qualifying Medicare beneficiaries with sepsis hospitalization between January 2013 and December 2014. Hospital survivors were followed for 180-days post-discharge, and mortality, readmissions, and new admission to skilled nursing facility were measured. Inpatient hospital-specific sepsis risk-adjusted mortality ratio (observed: expected) was the primary exposure.

RESULTS: A total of 830,721 …

The prognostic power of circulating cardiac biomarkers, their utility, and pattern of release in coronavirus disease 2019 (COVID-19) patients have not been clearly defined. In this multicentered retrospective study, we enrolled 3219 patients with diagnosed COVID-19 admitted to 9 hospitals from December 31, 2019 to March 4, 2020, to estimate the associations and prognostic power of circulating cardiac injury markers with the poor outcomes of COVID-19. In the mixed-effects Cox model, after adjusting for age, sex, and comorbidities, the adjusted hazard ratio of 28-day mortality for hs-cTnI (high-sensitivity cardiac troponin I) was 7.12 ([95% CI, 4.60-11.03] P<0.001), (NT-pro)BNP (N-terminal pro-B-type natriuretic peptide or brain natriuretic peptide) was 5.11 ([95% CI, 3.50-7.47] P<0.001), CK (creatine phosphokinase)-MB was 4.86 ([95% CI, 3.33-7.09] P<0.001), MYO (myoglobin) was 4.50 ([95% CI, 3.18-6.36] P<0.001), and CK was 3.56 ([95% CI, 2.53-5.02] P<0.001). The cutoffs of those cardiac biomarkers for effective prognosis of 28-day mortality of COVID-19 were found to be much lower than for regular heart disease at about 19%-50% of the currently recommended thresholds. Patients with elevated cardiac injury markers above the newly established cutoffs were associated with significantly increased risk of COVID-19 death. In conclusion, cardiac biomarker elevations are significantly associated with 28-day death in patients with COVID-19. The prognostic cutoff values of these biomarkers might be much lower than the current reference standards. These findings can assist in better management of COVID-19 patients to improve outcomes. Importantly, the newly established cutoff levels of COVID-19-associated cardiac biomarkers may serve as useful criteria for the future prospective studies and clinical trials.

OBJECTIVE: Dysregulated adipokine profiles contribute to the pathogenesis of diabetic cardiovascular complications. Endothelial cell (EC) dysfunction, a common pathological alteration in cardiovascular disorders, is exaggerated in diabetes. However, it is unclear whether and how dysregulated adipokines may contribute to diabetic EC dysfunction.

METHODS AND RESULTS: Serum C1q/TNF-Related Protein 5 (CTRP5) were determined in control/diabetes patients, and control/diabetic mice (high-fat diet, HFD). We observed for the first time that serum total CTRP5 was increased, high molecular weight (HMW) form was decreased, but the globular form (gCTRP5) was significantly increased in diabetic patients. These pathological alterations were reproduced in diabetic mice. To …

Powell, Kenzie A Cameron, David H Salzman, Dimitrios Papanagnou, Amanda Doty, Lori Latimer, Katherine Piserchia, William C Mcgaghie, Danielle M Mccarthy

Department of Emergency Medicine Faculty Papers

Clear communication with patients upon emergency department (ED) discharge is important for patient safety during the transition to outpatient care. Over one-third of patients are discharged from the ED with diagnostic uncertainty, yet there is no established approach for effective discharge communication in this scenario. From 2017 to 2019, the authors developed the Uncertainty Communication Checklist for use in simulation-based training and assessment of emergency physician communication skills when discharging patients with diagnostic uncertainty. This development process followed the established 12-step Checklist Development Checklist framework and integrated patient feedback into 6 of the 12 steps. Patient input was included as …

Department of Emergency Medicine Faculty Papers

Background: The Brugada pattern is identified on the EKG by a coved ST-segment elevation accompanied by a negative T wave in the early precordial leads in the absence of a cardiac structural abnormality. Brugada pattern and Brugada syndrome should be differentiated, as the latter is associated with an increased risk of sudden cardiac death.

Methods: The literature was searched using multiple databases to identify all the articles on Brugada pattern. Data were screened and analyzed by independent authors.

Results: Sixty articles, comprising 71 patients, were included in the study. The mean age of patients was 42.6 years, with a higher …

Pneumocephalus And Facial Droop On An Airplane: A Case Report, Irina Sanjeevan-Cabeza, Morgan Oakland

Department of Emergency Medicine Faculty Papers

Introduction: Pneumocephalus (PNC) is most commonly associated with trauma or intracranial surgery, less commonly secondary to an infectious source, and is rarely caused by barotrauma.

Case report: A 32-year-old woman presented to the emergency department with complaint of resolved left-sided facial droop and a lingering paresthesia of her left upper extremity after a cross-country flight. Computed tomography demonstrated several foci of air in the subdural space consistent with PNC.

Conclusion: For PNC to occur there must be a persistent negative intracranial pressure gradient, with or without an extracranial pressure change. In this case the pressure change occurred due to cabin …

E-Cigarette Or Vaping Product Use-Associated Lung Injury (Evali) Characterized By Pulmonary Ultrasound, Peter Sacci, Arthur Au

Department of Emergency Medicine Faculty Papers

Pulmonary ultrasound is a useful tool in the diagnosis and resuscitation of emergency department (ED) patients with dyspnea. We present the case of a patient who was diagnosed with E-cigarette or vaping product use-associated lung injury (EVALI) using pulmonary ultrasound. Many of these cases are diagnosed using x-ray, computerized tomography, or bronchoscopy and to our knowledge this is the first published case that demonstrates utility of ultrasound in diagnosing EVALI. While more investigation is needed on the use of this technique, the patient in this case was diagnosed with EVALI based on positive history, presence of normal cardiac function, non-cardiogenic …

Adiponectin Inhibits Cardiac Arrest/Cardiopulmonary Resuscitation‑Induced Apoptosis In Brain By Increasing Autophagy Involved In Adipor1‑Ampk Signaling., Yarong He, Bofu Liu, Peng Yao, Yuming Shao, Yanwei Cheng, Jie Zhao, Jiang Wu, Zhi Wei Zhao, Wen Huang, Theodore A. Christopher, Bernard Lopez, Xin-Liang Ma, Yu Cao

Department of Emergency Medicine Faculty Papers

Emerging evidence suggests that both apoptosis and autophagy contribute to global cerebral ischemia-reperfusion (GCIR)-induced neuronal death, which results from cardiac arrest (CA). However, the mechanism of how GCIR may affect the balance between apoptosis and autophagy resulting from CA remains to be elucidated. Additionally, the role of adiponectin (APN) in reversing the apoptosis and autophagy induced by GCIR following cardiac arrest-cardiopulmonary resuscitation (CA-C PR) is unclear. Thus, the aim of the present study was to investigate how GCIR affect the apoptosis and autophagy in response to CA and to clarify whether APN may alter the apoptosis and autophagy of neuronal …

What started as a cluster of patients with a mysterious respiratory illness in Wuhan, China, in December 2019, was later determined to be coronavirus disease 2019 (COVID-19). The pathogen severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), a novel Betacoronavirus, was subsequently isolated as the causative agent. SARS-CoV-2 is transmitted by respiratory droplets and fomites and presents clinically with fever, fatigue, myalgias, conjunctivitis, anosmia, dysgeusia, sore throat, nasal congestion, cough, dyspnea, nausea, vomiting, and/or diarrhea. In most critical cases, symptoms can escalate into acute respiratory distress syndrome accompanied by a runaway inflammatory cytokine response and multiorgan failure. As of this …

Department of Emergency Medicine Faculty Papers

Background Laboratory studies demonstrate glucose-insulin-potassium (GIK) as a potent cardioprotective intervention, but clinical trials have yielded mixed results, likely because of varying formulas and timing of GIK treatment and different clinical settings. This study sought to evaluate the effects of modified GIK regimen given perioperatively with an insulin-glucose ratio of 1:3 in patients undergoing cardiopulmonary bypass surgery. Methods and Results In this prospective, randomized, double-blinded trial with 930 patients referred for cardiac surgery with cardiopulmonary bypass, GIK (200 g/L glucose, 66.7 U/L insulin, and 80 mmol/L KCl) or placebo treatment was administered intravenously at 1 mL/kg per hour 10 minutes …

Mount Fuji Sign Following Nasal Polypectomy: Conservative Management Of Pneumocephalus, Matthew Szymaszek, Gentian Toshkezi

Department of Emergency Medicine Faculty Papers

Pneumocephalus is seen in conjunction with a variety of conditions, particularly traumatic injury, neurosurgical, and ears, nose, and throat (ENT) procedures. We describe the successful, non-operative management with supplemental oxygen of symptomatic pneumocephalus following polypectomy without further complication. This case adds to other case reports of pneumocephalus but differs in the non-invasive, conservative management with supplemental oxygen obviating the need for more invasive neurosurgical intervention such as decompressive craniectomy, burr holes, or drain placement.

Effective team building and leadership are crucial in running an effective and safe healthcare system with improved patient care and clinical outcomes. Currently, there is a great demand for formal leadership training throughout the extensive medical education curriculum. We constructed an interactive team-building activity utilizing gamification-theory with the Zoom game. The Zoom activity requires a team of learners to organize a set of sequential images, each of which contains a "zoomed out" section from the previous image, into the correct order within a set time frame. Given the unique and approachable nature of this team-based activity, we propose the following: …

Contemporary Nstemi Management: The Role Of The Hospitalist., Charles V Pollack, Alpesh Amin, Tracy Wang, Steven Deitelzweig, Marc Cohen, David Slattery, John Fanikos, Christopher Dilascia, Regan Tuder, Scott Kaatz

Department of Emergency Medicine Faculty Papers

Non-ST-segment elevation myocardial infarction (NSTEMI) is defined as elevated cardiac biomarkers of necrosis in the absence of persistent ST-segment elevation in the setting of anginal symptoms or other acute event. It carries a poorer prognosis than most ST-segment elevation events, owing to the typical comorbidity burden of the older NSTEMI patients as well as diverse etiologies that add complexity to therapeutic decision-making. It may result from an acute atherothrombotic event ('Type 1') or as the result of other causes of mismatch of myocardial oxygen supply and demand ('Type 2'). Regardless of type and other clinical factors, the hospital medicine specialist …

Implications Of C1q/Tnf-Related Protein Superfamily In Patients With Coronary Artery Disease., Yanwei Zhang, Caihong Liu, Jing Liu, Rui Guo, Zheyi Yan, Wenxia Liu, Wayne Bond Lau, Xiangying Jiao, Jimin Cao, Kun Xu, Yongping Jia, Xin-Liang Ma, Yajing Wang

Department of Emergency Medicine Faculty Papers

The C1q complement/TNF-related protein superfamily (CTRPs) displays differential effects on the regulation of metabolic homeostasis, governing cardiovascular function. However, whether and how they may serve as predictor/pro-diagnosis factors for assessing the risks of coronary artery disease (CAD) remains controversial. Therefore, we performed a clinical study to elaborate on the implication of CTRPs (CTRP1, CTRP5, CTRP7, and CTRP15) in CAD. CTRP1 were significantly increased, whereas CTRP7 and CTRP15 levels were decreased in CAD patients compared to the non-CAD group. Significant differences in CTRP1 levels were discovered between the single- and triple-vascular-vessel lesion groups. ROC analysis revealed that CTRP7 and CTRP15 may …

Sevoflurane Pre-Conditioning Ameliorates Diabetic Myocardial Ischemia/Reperfusion Injury Via Differential Regulation Of P38 And Erk., Dina Xie, Jianli Zhao, Rui Guo, Liyuan Jiao, Yanqing Zhang, Wayne Bond Lau, Bernard Lopez, Theodore Christopher, Erhe Gao, Jimin Cao, Xin-Liang Ma, Yajing Wang

Department of Emergency Medicine Faculty Papers

Diabetes mellitus (DM) significantly increases myocardial ischemia/reperfusion (MI/R) injury. During DM, cardioprotection induced by conventional pre-conditioning (PreCon) is decreased due to impaired AMP-activated protein kinase (AMPK) signaling. The current study investigated whether PreCon with inhaled anesthetic sevoflurane (SF-PreCon) remains cardioprotective during DM, and identified the involved mechanisms. Normal diet (ND) and high-fat diet (HFD)-induced DM mice were randomized into control and SF-PreCon (3 cycles of 15-minute period exposures to 2% sevoflurane) groups before MI/R. SF-PreCon markedly reduced MI/R injury in DM mice, as evidenced by improved cardiac function (increased LVEF and ±Dp/dt), decreased infarct size, and decreased apoptosis. To determine …
