Background: There is an increasing number of urgently ill and injured children being seen in emergency departments (ED) of developing countries. The pediatric disease burden in EDs across Pakistan is generally unknown. Our main objective was to determine the spectrum of disease and injury among children seen in EDs in Pakistan through a nationwide ED-based surveillance system. Methods: Through the Pakistan National Emergency Department Surveillance (Pak-NEDS), data were collected from November 2010 to March 2011 in seven major tertiary care centers representing all provinces of Pakistan. These included five public and two private hospitals, with a collective annual census of ...

Urinary Nitrate Might Be An Early Biomarker For Pediatric Acute Kidney Injury In The Emergency Department, Asad Mian, Yue Du, Harsha K Garg, Chantal Caviness, Stuart L Goldstein, Nathan S Bryan

Asad Mian

NO is involved in normal kidney function and perturbed in acute kidney injury (AKI). We hypothesized that urinary concentration of NO metabolites, nitrite, and nitrate would be lower in children with early AKI presenting to the emergency department (ED), when serum creatinine (SCr) was uninformative. Patients up to 19 y were recruited if they had a urinalysis and SCr obtained for routine care. Primary outcome, AKI, was defined by pediatric Risk, Injury, Failure, Loss of function, End-stage renal disease (pRIFLE) criteria. Urinary nitrite and nitrate were determined by HPLC. A total of 252 patients were enrolled, the majority (93%) of ...

Nitric Oxide And Its Metabolites In The Critical Phase Of Illness: Rapid Biomarkers In The Making, Asad Mian, Mayank Aranke, Nathan S. Bryan

Asad Mian

The potential of nitric oxide (NO) as a rapid assay biomarker, one that could provide a quantum leap in acute care, remains largely untapped. NO plays a crucial role as bronchodilator, vasodilator and inflammatory mediator. The main objective of this review is to demonstrate how NO is a molecule of heavy interest in various acute disease states along the emergency department and critical care spectrum: respiratory infections, central nervous system infections, asthma, acute kidney injury, sepsis, septic shock, and myocardial ischemia, to name just a few. We discuss how NO and its oxidative metabolites, nitrite and nitrate, are readily detectable ...

Long-Term Correction Of Ornithine Transcarbamylase Deficiency By Wpre-Mediated Overexpression Using A Helper-Dependent Adenovirus, Asad Mian, W.Michael Lmccormack, Viraj Mane, Soledad Kleppe, Philip Ng, Milton Finegold, William E. O'Brien, John R. Rodgers, Arthur L. Beaude, Brendan Lee

Asad Mian

The urea cycle disorders (UCDs) are important models for developing gene replacement therapy for liver diseases. Long-term correction of the most common UCD, ornithine transcarbamylase (OTC) deficiency, has yet to be achieved in clinical or preclinical settings. The single human clinical trial using early-generation adenovirus (Ad) failed to show any biochemical correction. In adult OTC-deficient mice, an E1/E2-deleted Ad vector expressing the mouse OTC gene, but not the human, was only transiently therapeutic. By using post-transcriptional overexpression in the context of the less immunogenic helper-dependent adenoviral vector, we achieved metabolic correction of adult OTC-deficient mice for >6 months. Demonstrating ...

Nitric Oxide Metabolites As Biomarkers For Influenza-Like Acute Respiratory Infections Presenting To The Emergency Room, Asad Mian, Federico R Laham, Andrea T Cruz, Harsha Garg, Charles G Macias, A. Chantal Caviness, Pedro A Piedra

Asad Mian

Aims: Nitric oxide (NO) is increased in the respiratory tract in pulmonary infections. The aim was to determine whether nasal wash NO metabolites could serve as biomarkers of viral pathogen and disease severity in children with influenza-like illness (ILI) presenting to the emergency department (ED) during the 2009 influenza A H1N1 pandemic. Methods: Children ≤18 years old presenting to the ED with ILI were eligible. Nasal wash specimens were tested for NO metabolites, nitrate and nitrite, by HPLC and for respiratory viruses by real-time PCR. Results: Eighty-nine patients with ILI were prospectively enrolled during Oct-Dec, 2009. In the entire cohort ...

Nitric oxide (NO) is crucial in diverse physiological and pathological processes. We show that a hypomorphic mouse model of argininosuccinate lyase (encoded by Asl) deficiency has a distinct phenotype of multiorgan dysfunction and NO deficiency. Loss of Asl in both humans and mice leads to reduced NO synthesis, owing to both decreased endogenous arginine synthesis and an impaired ability to use extracellular arginine for NO production. Administration of nitrite, which can be converted into NO in vivo, rescued the manifestations of NO deficiency in hypomorphic Asl mice, and a nitric oxide synthase (NOS)-independent NO donor restored NO-dependent vascular reactivity ...

Overcrowding In The Emergency Departments: Challenges And Opportunities For Improvement, Muhammad Akbar Baig, Asad Mian, Fatima Najeeb, Hira Shahzad

Asad Mian

With the advent of Emergency Medicine, one can observe an increase in the number of Emergency Departments (ED) across the country. However, most EDs struggle due to an overwhelming number of patients. Overcrowding can lead to delays in patient care. For a city like Karachi which is an active disaster zone, preemptive preparedness is required in the face of terror threats and such overcrowding needs to be decreased to a bare minimum. The most frequent causes of prolonged length of stay (LOS) in the ED include non-availability of in-hospital beds, delays in response to subspecialty consultations and escalating medical expenses ...

Accurate Cytogenetic Biodosimetry Through Automated Dicentric Chromosome Curation And Metaphase Cell Selection, Jin Liu, Yanxin Li, Ruth Wilkins, Canadian Nuclear Laboratories, Joan H. Knoll, Peter Rogan

Biochemistry Publications

Accurate digital image analysis of abnormal microscopic structures relies on high quality images and on minimizing the rates of false positive (FP) and negative objects in images. Cytogenetic biodosimetry detects dicentric chromosomes (DCs) that arise from exposure to ionizing radiation, and determines radiation dose received based on DC frequency. Improvements in automated DC recognition increase the accuracy of dose estimates by reclassifying FP DCs as monocentric chromosomes or chromosome fragments. We also present image segmentation methods to rank high quality digital metaphase images and eliminate suboptimal metaphase cells. A set of chromosome morphology segmentation methods selectively filtered out FP DCs ...

BACKGROUND: Hospitals around the world are faced with the issue of boarders in emergency department (ED), patients marked for admission but with no available inpatient bed. Boarder status is known to be associated with delayed inpatient care and suboptimal outcomes. A new care delivery system was developed in our institution where boarders received full inpatient care from a designated medical team, acute medical team (AMT), while still residing at ED. The current study examines the impact of this AMT intervention on patient outcomes.

METHODS: We conducted a retrospective quasi-experimental cohort study to analyze outcomes between the AMT intervention and conventional ...

Cardiac Arrest Risk Standardization Using Administrative Data Compared To Registry Data., Anne V. Grossestreuer, David F. Gaieski, Michael W. Donnino, Joshua I.M. Nelson, Eric L. Mutter, Brendan G. Carr, Benjamin S. Abella, Douglas J. Wiebe

Department of Emergency Medicine Faculty Papers

BACKGROUND: Methods for comparing hospitals regarding cardiac arrest (CA) outcomes, vital for improving resuscitation performance, rely on data collected by cardiac arrest registries. However, most CA patients are treated at hospitals that do not participate in such registries. This study aimed to determine whether CA risk standardization modeling based on administrative data could perform as well as that based on registry data.

METHODS AND RESULTS: Two risk standardization logistic regression models were developed using 2453 patients treated from 2000-2015 at three hospitals in an academic health system. Registry and administrative data were accessed for all patients. The outcome was death ...

Danshen-Chuanxiong-Honghua Ameliorates Cerebral Impairment And Improves Spatial Cognitive Deficits After Transient Focal Ischemia And Identification Of Active Compounds., Xianhua Zhang, Wan Zheng, Tingrui Wang, Ping Ren, Fushun Wang, Xin-Liang Ma, Jian Wang, Xi Huang

Department of Emergency Medicine Faculty Papers

Previously, we only apply a traditional Chinese medicine (TCM) Danshen-Chuanxiong-Honghua (DCH) for cardioprotection via anti-inflammation in rats of acute myocardial infarction by occluding coronary artery. Presently, we select not only DCH but also its main absorbed compound ferulic acid (FA) for cerebra protection via similar action of mechanism above in animals of the transient middle cerebral artery occlusion (tMCAO). We investigated whether oral administration of DCH and FA could ameliorate MCAO-induced brain lesions in animals. By using liquid chromatography-tandem mass spectrometry (LC-MS/MS), we analyzed four compounds, including tanshinol, salvianolic acid B, hydroxysafflor yellow A and especially FA as the ...

Emergency Department Super-Utilizer Program Involvement: Pilot Data And Methods Challenges, Colette Houssan, Arlene S. Ash, Rachel Davis-Martin, Laurel Banach, Eric W. Dickson, Edwin D. Boudreaux

Edwin D. Boudreaux

Super-utilizers are patients who use extreme amounts of medical services, often due to comorbid medical, social, and mental health issues. The MyLink Evaluation Project (MEP) studies MyLink, a program that connects super-utilizers with community support workers (CSWs) to improve the patient experience and reduce costs. The MEP-eligible population is ≥18 years old with at least 5 Emergency Department (ED) visits within 12 months and no other exclusions (e.g., language barriers, living out-of-region). During MEP’s pilot, among 58 eligible patients, 28 consented to being referred to MyLink and followed up. Of these, 7 could not be located for follow-up ...

Implementing An Undergraduate, Team-Based, First Aid Education Course, Valerie O'Toole-Baker, Carol A. Amann, Stephanie N. Mcelhaney, Michael Mccarthy, Jestin N. Carlson

International Journal of First Aid Education

Abstract

First aid (FA) skills, including Cardiopulmonary Resuscitation (CPR) are the foundation of first responder care. Best practice guidelines to educate FA trainees are lacking. The current structure of FA training programs is based on pedagogy, derived indirectly from hospital-based and Emergency Medical Services training models. Most FA training programs focus on educating the participant to function as the sole provider of care; however there may be instances when individuals providing FA find themselves suddenly engaged as functioning members of teams caring for an individual in need. Findings indicate that patients are safer and receive higher quality care when providers ...
