SARS-CoV-2 infection and its association with thrombosis and ischemic stroke: a review
This review of current literature provides background to the COVID-19 pandemic, as well as an examination of potential pathophysiologic mechanisms behind development of thrombosis and ischemic stroke related to COVID-19. SARS-CoV-2 infection is well-documented to cause severe pneumonia, however, thrombosis and thrombotic complications, such as ischemic stroke, have also been documented in a variety of patient demographics. SARS-CoV-2 infection is known to cause a significant inflammatory response, as well as invasion of vascular endothelial cells, resulting in endothelial dysfunction.

Inter-facility transfer for patients with acute large vessel occlusion stroke receiving mechanical thrombectomy
Mechanical thrombectomy (MT) is the preferred treatment for large vessel occlusion (LVO) ischemic stroke, and neurological outcome improves with earlier treatment. Patients with LVO frequently require inter-facility transfer to access MT but delays at transferring EDs may worsen neurological outcomes.

Impact of creatinine screening on contrast-induced nephropathy following computerized tomography for stroke
This study sought to evaluate rates of acute kidney injury in patients undergoing contrast-enhanced computerized tomography for acute stroke in the emergency department (ED) before and after the cessation of creatinine screening.

Mucormycosis with orbital compartment syndrome in a patient with COVID-19
AbstractDuring the current pandemic of COVID-19, a myriad of manifestations and complications has emerged and are being reported on. We are discovering patients with COVID-19 are at increased risk of acute cardiac injury, arrythmias, thromboembolic complications (pulmonary embolism and acute stroke), and secondary infection to name a few. I describe a novel case of COVID-19 in a previously healthy 33-year-old female who presented for altered mental status and proptosis. She was ultimately diagnosed with mucormycosis and orbital compartment syndrome, in addition to COVID-19.

Does prolonged emergency department length of stay(EDLOS) affect the outcomes of acute ischemic stroke patients?
The effect of emergency department length of stay (EDLOS) on outcomes of patients with acute ischemic stroke (AIS) remains largely unexamined. We aimed to investigate the association between EDLOS and outcomes in AIS patients.

Can non-contrast head CT and stroke severity be used for stroke triage? A population-based study
Acute ischemic stroke (AIS) patients may benefit from endovascular thrombectomy (EVT) up to 24  h since last known normal (LKN). Advanced imaging is required for patient selection. Small or rural hospitals may not have sufficient CT technician and radiology support to rapidly acquire and interpret images. We estimated transfer rates using non-contrast head CT and stroke severity to select p atients to be transferred to larger centers for evaluation.

A unique presentation of Colovesical fistula
A colovesical fistula (CVF) is a pathological connection between the colon and the urinary bladder. Although they are uncommon, consequences can severely affect quality of life and mortality. Diverticula are the most common cause of CVF. This case details a patient's CVF diagnosis in the emergency department with unremitting gastrointestinal and urinary symptoms.A 78-year-old male patient with recent hospitalization for stroke and left carotid endarterectomy complicated by urinary retention treated with a Foley catheter presented to the Emergency Department with a chief complaint of hematuria and unremitting diarrhea.

Retrospective analysis of the hemodynamic consequences of prehospital supplemental oxygen in acute stroke
This study examines the hemodynamic consequences of prehospital sO2 in stroke.

The significance of repetitive yawning in the emergency patient - A warning of imminent death or disability
Premortem yawning is absent from almost all major medical textbooks but has been associated for more than 2000  years with impending death from acute infections and hemorrhage and was commonly known during the Bubonic Plague pandemic [1,2]. Medical reports of premortem yawning identify multiple causes of shock including vasovagal reflex, severe hypoxia/anemia/hypoglycemia, stroke, and intracranial hyperten sion [3-5].

Thyrotoxicosis and bilateral internal carotid artery dissections
Cervical artery dissection is a rare but important diagnosis to consider in young patients presenting with stroke. Multiple etiologies of cervical artery dissections have been previously reported, but the association with thyrotoxicosis is extremely rare. A previously healthy 43-year-old female presented to the emergency department with new symptoms related to thyrotoxicosis and bilateral internal carotid artery dissections. Her atrial fibrillation and hypertension resolved by treating the underlying hyperthyroidism with methimazole and propranolol.

Priapism in a patient with coronavirus disease 2019 (COVID-19)
Thromboembolic complications related to SARS-CoV-2 have been extensively reported. They include deep vein thrombosis, pulmonary embolism, ischemic stroke, and acute coronary syndrome. Penile thrombosis has not been reported as a thrombotic complication of SARS-CoV-2 infection with hypercoagulability.Here we describe a case of priapism as a thromboembolic complication in a patient with COVID-19 who recovered from acute respiratory distress syndrome (ARDS). We discuss the underlying pathophysiological mechanisms mainly related to an hypercoagulability state.

Prehospital oxygen for stroke victims
It was of great interest to read Dr. Dylla and colleagues' well-done retrospective cohort study investigating prehospital oxygen treatment in acute stroke patients [1]. It was also very informative to read Dr. Zhang's review [2] and the authors' response [3].

Thromboelastography for prediction of hemorrhagic transformation in patients with acute ischemic stroke
Thromboelastography (TEG) provides a rapid assessment of the hemostatic processes of a patient in emergency settings. There are limited data on TEG as a predictive tool for hemorrhagic transformation in patients with acute ischemic stroke. We investigated whether TEG values on admission could predict hemorrhagic transformation in patients with acute ischemic stroke.
