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 …

Objective: We aim to examine the mechanisms of head-injured children presenting to participating centres in the Pan Asian Trauma Outcomes Study (PATOS) and to evaluate the association between mechanism of injury and severe outcomes.
Design and Setting: We performed a retrospective review of medical records among emergency departments (EDs) of eight PATOS centres, from September 2014 - August 2015.
Participants: We included children <16 years old who presented within 24 hours of head injury and were admitted for observation or required a computed tomography (CT) of the brain from the ED. We excluded children with known coagulopathies, neurological co-morbidities or prior neurosurgery. We reviewed the mechanism, intent, location and object involved in each injury, and the patients' physical findings on presentation.
Outcomes: Primary outcomes were death, endotracheal intubation or neurosurgical intervention. Secondary outcomes included hospital and ED length of stay.
Results: 1438 children were analysed. 953 children (66.3%) were male and the median age was 5.0 years (IQR …

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 …

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 putative …

The Role Of The Heart Score And Clinical Decision Units In Ed Patients With Chest Pain, Gregory Jasani, Jesse M. Pines, Caitlin Carter

Center for Health Care Quality

Every year, millions of patients present to Emergency Departments across the country complaining of chest pain. Even after traditional ED testing which includes electrocardiograms, laboratory testing, and chest radiography, chest pain patients still have a small but real risk of serious illness. The HEART score is a new tool that has been validated to help risk-stratify patients. Clinical Decision Units decrease cost and length of stay without compromising patient safety, allowing for complete evaluations of these patients.

OBJECTIVE: Acute mountain sickness (AMS) is defined by patient-reported symptoms using the Lake Louise Score (LLS), which provides limited insight into any possible underlying central nervous system (CNS) dysfunction. Some evidence suggests AMS might coexist with altered neural functioning. Cognitive impairment (CI) may go undetected unless a sensitive test is applied. Our hypothesis was that a standardized test for mild CI would provide an objective measure …

Diagnostic Effectiveness Of High-Sensitivity Troponins, Sean R. Bodin, Jacqueline Ramirez

Physician Assistant Capstones, 2016 to 2019

Background: Acute myocardial infarctions (AMI) are a leading cause of death in the United States. The key to increasing survivability is early recognition to expedite the proper treatment modalities. In conjunction with the clinical presentation and electrocardiograms, the use of cardiac biomarkers is exponentially important in not only recognizing a cardiac event but also determining the extent of injury. Advancement in laboratory technology has led to the development of high-sensitive troponin (hs-troponin) assays which can detect smaller cardiac troponin serum levels compared to conventional troponin assays. This implies that the use of hs-troponin assays is more effective in the …

Application Of D-Dimer To Aid In Diagnosis Of Acute Aortic Dissection, Hannah Scarboro, Julia Starkey

Physician Assistant Capstones, 2016 to 2019

Introduction: Acute aortic dissection (AAD) is an emergent, relatively uncommon condition that typically presents with sudden onset severe chest or back pain.1 Advanced imaging, such as computerized tomography, is currently the gold standard to diagnose AAD; this can be expensive and unavailable at all health care centers. D-dimer is a blood test that has been shown in recent studies to be elevated in acute aortic dissection. This may be a more cost-effective way to help the clinician “rule-out” an acute aortic dissection.1

Objective: The purpose of this research was to determine if there is significant data regarding the sensitivity and …

Emergency Department Approach To Electrical Toothbrush Associated Hand Injury, A Unique Case Of Non-Oropharyngeal Injury., Hannah Robinson, Neal Sikka, Chimere Little, Ali Pourmand

GW Research Days 2016 - 2020

Puncture wounds are common injuries treated in the emergency department (ED). Prior studies have shown that toothbrushes are common reservoirs for oral flora, especially in regions near the head of the toothbrush near the bristles. ED providers must be aware of the danger associated with bacterial contamination of the associated wound and should be familiar with different pathogens and options for treatment. We present a unique case of a 30-year-old male with non-intraoral injury who presented to the ED after puncturing his left palm with the metal post of an electric toothbrush.

Concussion Screening Evaluation: Bess Vs Sway, Zachariah Hatoum, Aidan Neustadtl, Jeremy Altman, Aurash Zarrinbakhsh, David Milzman

GW Research Days 2016 - 2020

Introduction: Rapid evaluation of concussion is important in the pre-hospital setting as an easy test. It is also useful in the ED, as too often little is done for concussed patients. The Balance Error Scoring System (BESS) is the current gold standard for evaluating balance, one of the best predictors of concussion. SWAY, a new gyroscope based iPhone application, is being proposed as a more sensitive and more objective test than BESS. This study will compare Sway to BESS to determine if there is equal efficacy.
Method: 74 scholastic and collegiate athletes were administered baseline balance evaluations using Sway. …
