BackgroundEmergency department observation units (EDOUs) are used frequently for low-risk chest pain evaluations.ObjectiveThe purpose of this study was to determine whether geriatric compared to non-geriatric patients evaluated in an EDOU for chest pain have differences in unscheduled 30-day re-presentation, length of stay (LOS), and use of stress testing.MethodsWe conducted an exploratory, retrospective, cohort study at a single academic, urban ED of all adult patients placed in an EDOU chest pain protocol from June 1, 2014 to May 31, 2015. Our primary outcome was any unscheduled return visits within 30 days of discharge from the EDOU. Secondary outcomes included EDOU LOS and stress testing. We used Wilcoxon non-parametric and χ² tests to compare geriatric to non-geriatric patients.ResultsThere were 959 unique EDOU placements of geriatric (n = 219) and non-geriatric (n = 740) patients. Geriatric compared to non-geriatric patients had: no significant difference in unscheduled 30-day return visits after discharge from the EDOU (15.5% vs. 18.5%; p = 0.31); significantly longer median EDOU LOS (22.1 vs. 20.6 h; p < 0.01) with a greater percentage staying longer than 24 h (42% vs. 29.1%; p < 0.01). Geriatric patients had significantly fewer stress tests (39.7% vs. 51.4%; p < 0.01), more of which were nuclear stress tests (78.2% vs. 39.5%; p < 0.01).ConclusionsIn this exploratory retrospective study, geriatric EDOU chest pain patients did not have an increased rate of re-presentation to the hospital within 30 days compared to non-geriatric patients. Geriatric patients had a longer EDOU LOS than non-geriatric patients. Geriatric patients in the EDOU had fewer stress tests, but more of those were nuclear stress tests.

Failure of Intracardiac Pacing After Fatal Propafenone Overdose: A Case Report

Publication date: Available online 11 January 2018
Source:The Journal of Emergency Medicine
Author(s): Ivan Zeljković, Nikola Bulj, Matea Kolačević, Vedran Čabrilo, Diana Delić Brkljačić, Šime Manola
BackgroundPropafenone is a sodium-channel blocker, class IC antiarrhythmic drug, frequently used to manage supraventricular dysrhythmias, especially atrial fibrillation. We report a self mono-intoxication with propafenone.Case ReportA 68-year-old woman presented with a decreased level of consciousness, hypotension, and electrocardiogram showing QRS widening with atrial asystole and extreme bradycardia < 20 beats/min. After initial stabilization with transcutaneous pacing, laboratory findings detected normal electrolyte ranges and metabolic acidosis, and her medical history revealed availability of propafenone due to paroxysmal atrial fibrillation and depressive syndrome, which led to the suspicion of intoxication. Despite intravenous sodium bicarbonate, calcium, norepinephrine, and aggressive fluid replacement (10% glucose with insulin), hemodynamic stability was not achieved. Temporary intracardiac pacing was implanted. However, even with multiple electrode positions, effective capture could not be achieved. At that time, transcutaneous pacing was also ineffective. Consequently, the patient died in refractory asystole due to complete myocardial nonexcitability. The concentration of 5270 ng/mL of propafenone was found in the blood at autopsy, using gas spectrometry–mass chromatography. It is the third highest reported propafenone lethal concentration and the first case in which the myocardial nonexcitability refractory to intracardiac pacing was seen despite normal electrode position in the right ventricle, with failure to achieve the patient's hemodynamic stability.Why Should an Emergency Physician Be Aware of This?Emergency physicians should be aware of possible propafenone ingestion causing toxicity, which is probably more frequent than previously described, especially because propafenone is widely available due to its use in managing atrial fibrillation, the most common arrhythmia nowadays.

Posterior Reversible Encephalopathy Syndrome: A Rare Childhood Case with Unconsciousness

Publication date: Available online 12 January 2018
Source:The Journal of Emergency Medicine
Author(s): Akira Komori, Daisuke Mizu, Koichi Ariyoshi
BackgroundPosterior reversible encephalopathy syndrome (PRES) is a condition characterized by seizures, altered consciousness, visual disturbances, and headache. Characteristic findings on neuroimaging include cerebral edema, typically involving the parieto-occipital white matter. PRES has been associated with hypertension, autoimmune disease, and Henoch-Schölein purpura (HSP), but few cases have been reported, and fewer cases of PRES have been reported in children.Case ReportWe report the case of a 4-year-old girl who presented with blindness and semi-consciousness. The patient had no significant medical history and no abnormalities on physical examination or laboratory testing, although she had slightly elevated blood pressure. After hospitalization, the patient showed some characteristic signs of HSP and cranial magnetic resonance imaging revealed PRES as the cause of semi-consciousness. In our discussion, we examine the clinical features of PRES and remarkable points for the clinical diagnosis and management of this rare but important disease.Why Should an Emergency Physician Be Aware of This?Although reports of PRES in children are rare, PRES should be considered in the differential diagnosis of children presenting with disturbance of consciousness. Emergency physicians should consult with pediatric physicians to confirm diagnoses of PRES and determine an appropriate treatment plan, given its variable etiology. Measurements of blood pressure, which are often missing in pediatric cases, can help physicians to arrive at a correct diagnosis.

Professional quality of life, wellness education, and coping strategies among emergency physicians

Abstract

Professional quality of life (ProQOL) is affected by and affects professional well-being and performance. The objectives of this study are to identify risk factors of ProQOL among EM physicians in Zagazig University hospitals (ZUHs), to detect the relationship between ProQOL and coping strategies, and to measure the implication of the Worksite Wellness Education (WWE) program on improving knowledge skills, ProQOL, and coping. An intervention study was conducted among 108 EM physicians at ZUHs through two stages: assessing ProQOL subscales (CS, BO, and STS) and coping strategies and conducting the WWE program. A pre–post-test design was used in the evaluation. CS was higher among the older age group, smokers, nighttime sleepers, and hobbies' practitioners. Coping strategies carried out by EM physicians to overcome stress and their ProQOL scores were improved significantly post program. ProQOL has multiple factors that affect it. Applying the WWE program will address this concept and may raise awareness about how to cope with work stressors.

An integrated fuzzy-based advanced eutrophication simulation model to develop the best management scenarios for a river basin

Abstract

Assessment of water quality status of a river with respect to its discharge has become prerequisite to sustainable river basin management. The present paper develops an integrated model for simulating and evaluating strategies for water quality management in a river basin management by controlling point source pollutant loadings and operations of multi-purpose projects. Water Quality Analysis and Simulation Program (WASP version 8.0) has been used for modeling the transport of pollutant loadings and their impact on water quality in the river. The study presents a novel approach of integrating fuzzy set theory with an "advanced eutrophication" model to simulate the transmission and distribution of several interrelated water quality variables and their bio-physiochemical processes in an effective manner in the Ganges river basin, India. After calibration, simulated values are compared with the observed values to validate the model's robustness. Fuzzy technique of order preference by similarity to ideal solution (F-TOPSIS) has been used to incorporate the uncertainty associated with the water quality simulation results. The model also simulates five different scenarios for pollution reduction, to determine the maximum pollutant loadings during monsoon and dry periods. The final results clearly indicate how modeled reduction in the rate of wastewater discharge has reduced impacts of pollutants in the downstream. Scenarios suggesting a river discharge rate of 1500 m³/s during the lean period, in addition to 25 and 50% reduction in the load rate, are found to be the most effective option to restore quality of river Ganges. Thus, the model serves as an important hydrologic tool to the policy makers by suggesting appropriate remediation action plans.

Biological materials are multifunctional performing more than one function in a perfect synergy. These materials are built from fairly simple and limited components at ambient conditions. Such judicious designs have proven elusive for synthetic materials. Here, we demonstrate a multifunctional phase change (pc) composite from simple building blocks, which exhibits high stiffness and optical transmittance control. We show an increase of more than one order of magnitude in stiffness when we embed paraffin wax spheres into an elastomer matrix, polydimethylsiloxane (PDMS) in a dynamic compression test. High stiffness is mainly influenced by presence of microcrystals within the wax. We further show fast temperature-controlled optical switching of the composite for an unlimited number of cycles without any noticeable mechanical degradation. Through experimental and finite element method, we show high energy absorption capability of pc-composite. Based on these properties, the pc-composite could be used as an effective coating on glasses for cars and windows. This simple approach to multi-functionality is exciting and could pave way for designs of other multifunctional materials at the macro-scale.

Heterogeneous catalysis by gold and gold-based bimetal nanoclusters

Publication date: Available online 12 January 2018
Source:Nano Today
Author(s): Jianbo Zhao, Rongchao Jin
Gold and gold-based bimetallic catalysts have shown great potential for many important chemical transformation reactions owing to their good activity and high selectivity under relatively mild conditions. However, elucidating their structure-property relationships remains a major challenge because of size distributions and ill-defined structures (i.e. structural heterogeneity) of conventional nanoparticle catalysts. Recently, controlled synthesis of homogold and gold-based bimetal nanoclusters with precise atom numbers have been accomplished, and more importantly their atomic structures have been elucidated, which provide new model systems for understanding the catalytic behavior at the atomic level. Due to their ultra-small size, gold and bimetal nanoclusters exhibit unique properties, which contribute to novel catalysts or precatalysts for many chemical reactions. Herein, we review the recent progress in the catalytic research of atomically precise gold and gold-based bimetal nanoclusters. Specifically, this review covers the application of nanoclusters with or without ligands as catalysts for reactions such as selective oxidation, selective hydrogenation, C–C coupling and photocatalysis. Finally, we provide some future perspectives about metal nanocluster catalysis.
