Cardiac calcified amorphous tumour: an unusual aetiology for recurrent cardioembolic strokes.

We report an elderly woman with vascular risk factors and recurrent cardioembolic strokes in whom the stroke aetiology was finally ascertained to be a calcified amorphous tumour of the heart after repeated negative investigations for embolic aetiology over 2 years. This report discusses the clinical and imaging characteristics of calcified amorphous tumours of the heart with emphasis of recent advances in cardiac imaging.

Racial Impact on Inpatient Stroke Quality of Care in Two Community Hospitals.

Introduction: This analysis was conducted as a part of a quality improvement project aiming at identifying racial disparity in inpatient stroke quality of care.

Methods: The Get With The Guidelines (GWTG) database was used to identify all patients discharged with any stroke diagnosis between January and December 2021. An additional chart review was conducted to ensure the accuracy of racial/ethnic categorization.

Describing Racial Disparity in Hypertension Control in a Large Minnesota Outpatient Practice.

Introduction: This analysis is a part of ongoing quality improvement efforts aiming at improving hypertension control among various racial minority groups seen in a large outpatient practice with a special focus on two war refugee populations, the Hmong and the Somali populations.

Method: Deidentified medical records were reviewed for adult hypertensive patients who had an outpatient encounter with a hypertension diagnosis during the years 2015 through 2019. The study outcome was the rate of uncontrolled hypertension, defined as systolic blood pressure ≥140 mm Hg or diastolic blood pressure ≥90 mm Hg, and stratified by race, age, and gender.

Stroke Characteristics in a Cohort of Hmong American Patients.

Background Prior studies have indicated high rates of vascular risk factors, but little is known about stroke in Hmong. Methods and Results The institutional Get With The Guidelines (GWTG) database was used to identify patients discharged with acute ischemic stroke, intracerebral hemorrhage, or subarachnoid hemorrhage between 2010 and 2019. Hmong patients were identified using clan names and primary language.

Potentially Preventable Readmissions After Acute Inpatient Rehabilitation.

Objective: The aim of the study is to identify causes and risk factors for potentially preventable readmissions of patients discharged from an inpatient rehabilitation facility.

Design: Our hospital billing database was used to identify patients discharged from our inpatient rehabilitation facility between 2013 and 2018 and experienced a potentially preventable readmission within 90 days ( n = 75). Retrospective chart review was completed to obtain clinical data.

Hmong Stroke Knowledge Survey.

The Hmong are an ethnic group from Southeast Asia who migrated in large numbers to the United States after the end of the Vietnam War and are now clustered in several parts of the country, including our city. Based on a retrospective review of medical records and on our anecdotal experience, we suspected that there was a gap in stroke knowledge in our Hmong patients. This stroke knowledge survey was intended to uncover any knowledge gaps within the Hmong community before engaging in community awareness activities.

Readmission to an Acute Care Hospital During Inpatient Rehabilitation After Stroke.

Objective: The aim of the study was to identify causes for readmission to acute care of patients admitted to inpatient rehabilitation facility after stroke.

Design: The institutional Uniform Data System for Medical Rehabilitation database was used to identify stroke patients who experienced readmission to acute care and an equal number of age-/sex-matched group of patients who successfully completed their inpatient rehabilitation facility stay during 2005-2018. Retrospective chart review was used to extract clinical data.

Patterns and Predictors of Extra-Corporeal Membrane Oxygenation Related Cerebral Microbleeds.

Objectives: Recent case-reports have described an atypical cerebral microbleed (CMB) topography after extracorporeal membrane oxygenation (ECMO). The objective of this study was to examine the prevalence, radiographic patterns, and clinical correlates of possibly-ECMO-related (PER) CMB.

Materials And Methods: We performed a retrospective study of 307 consecutive patients receiving ECMO support at our tertiary-care University Hospital (2013-2018).

Soliton mode-locked fiber laser for distance measurements.

Absolute distance measurement is crucial for many applications including metrology, large-scale manufacturing, range finding, and surveying. In this paper, a novel, to the best of our knowledge, technique is introduced for precise distance measurement by including the distance under measurement in a soliton mode-locked fiber ring laser (SMFRL). Consequently, the measured distance can be calculated from the change in the repetition rate of the emitted pulses due to the laser cavity length change.

Transient Global Amnesia as a Possible First Manifestation of COVID-19.

Evidence of involvement of the nervous system in COVID-19 disease is accumulating. We describe a case of a 53-year-old man presented with classic syndrome of transient global amnesia with symptoms lasting less than 24 hours and mild transient unexplained fever. Workup including brain MRI, electroencephalogram, and chest X ray was negative and the patient was discharged.

Congenital Heart Disease in Syrian Refugee Children: The Experience at a Tertiary Care Center in a Developing Country.

The influx of Syrian refugees to Lebanon that began in 2012 created new health-care and financial stressors on the country with an increase in communicable and non-communicable diseases. This study aims to describe the presentations, diagnoses, management, financial burden, and outcomes among Syrian refugees with congenital heart disease (CHD) in Lebanon. This is a retrospective study that was conducted through reviewing the charts of all Syrian pediatric patients referred to the Children's Heart Center at the American University of Beirut Medical Center for evaluation between the years 2012 and 2017.

A 56-Year-Old Woman with Recurrent Strokes: A Clear Case with a Therapeutic Dilemma.

A 56-year-old woman with a history of cerebral amyloid angiopathy (CAA) complicated by prior intracranial hemorrhage (ICH) was evaluated for an asymptomatic ischemic stroke discovered on screening brain MRI. On echocardiogram, she was found to have a mass on her mitral valve and strongly positive antiphospholipid antibodies. She was diagnosed with nonbacterial thrombotic (Libman-Sacks) endocarditis associated with the primary antiphospholipid syndrome (APS).

Using femtosecond laser pulses for electronic distance meter calibration.

Electronic distance meters (EDMs) are widely used in different applications, such as surveying and civil engineering. In order to calibrate an EDM, different techniques can be used, including displacement interferometers and reference baselines. In this paper, an indoor baseline is designed and then accurately measured using femtosecond laser pulses from an optical frequency comb to be used for EDM calibration.

Hmong Cross-Cultural Adaptation of Stroke Educational Material.

Background: The presence of significant cultural and language barriers can affect timely, effective dissemination of stroke education for Hmong patients. Our aim was to design stroke educational material suitable for the Hmong community, using culturally sensitive strategies and patient education best practices.

Methods: We collaborated with the American Heart Association/American Stroke Association to adapt existing English educational material for use among Hmong patients.

A Successful Quality Improvement Project for Detection and Management of Acute Stroke in Hospitalized Patients.

Background: The incidence rate of stroke in hospitalized patients ranges between 2% and 17% of all strokes-a higher rate than in the community. Delays in recognition and management of stroke in hospitalized patients lead to worse outcomes. At our hospital, the existing in-hospital stroke (IHS) code showed low usage and effectiveness.

Support of New Triage Protocol among Acute Stroke Care Providers.

Objective: We conducted an online survey to gauge the acceptance of sending acute stroke patients with suspected large vessel occlusion (LVO) directly to an endovascular-capable hospital (ECH) even if that means bypassing a closer alteplase-capable hospital (ACH) without endovascular capability.

Methods: The survey was composed of two cases of acute stroke, one with cortical symptoms suggestive of LVO and the other without. In each case, responders were asked to choose between triaging to a closer ACH or an ECH that is further away and to provide an opinion regarding the maximum extra travel time they would tolerate if they chose the ECH.

Rates and predictors of futile recanalization in patients undergoing endovascular treatment in a multicenter clinical trial.

Purpose: The phenomenon of futile recanalization, defined as lack of clinical benefit despite angiographic recanalization, is an important limitation of endovascular treatment for acute ischemic stroke. We aim to characterize the occurrence and predictors of futile recanalization in the endovascular arm of the Interventional Management of Stroke (IMS) III trial.

Methods: Patients with near complete or complete recanalization (TICI grades 2b and 3) were divided according to functional outcome at 3 months into "meaningful recanalization," defined as mRS score 0-2, and "futile recanalization," mRS score 3-6.

Statewide Trends in Utilization and Outcomes of Endovascular Treatment of Acute Ischemic Stroke: Analysis of Minnesota Hospital Association Data (2014 and 2015).

Background: The study aims at examining the changes in endovascular procedures utilization after the publication of the clinical trials showing their benefit in patients with acute ischemic stroke (AIS).

Methods: Minnesota Hospital Association database from 137 member hospitals was used to calculate the statewide utilization rates for 2 periods: prior to (calendar year 2014) and after (calendar year 2015) the publication of multiple randomized clinical trials showing the efficacy of endovascular therapy. Patients were identified using International Classification of Disease, Clinical Modification, 9th revision (ICD-9) or ICD-10 codes (ICD-10 started October 2015).

Searching for the Smoker's Paradox in Acute Stroke Patients Treated With Intravenous Thrombolysis.

Background: Inconsistent evidence supports better outcome in smokers after stroke. Our study examines this association in a large sample of ischemic stroke treated with intravenous thrombolysis.

Method: Virtual International Stroke Trials Archive (VISTA) database, composed of individual patient data of multiple clinical trials, was queried.
