Most naming error lesion-symptom mapping (LSM) studies have focused on semantic and/or phonological errors. Anomic individuals also produce unrelated word errors, which may be linked to semantic or modality-independent lexical deficits. To investigate the neural underpinnings of rarely-studied unrelated errors, we conducted LSM analyses in 100 individuals hospitalised with a left hemisphere stroke who completed imaging protocols and language assessments. We used least absolute shrinkage and selection operator regression to capture relationships between naming errors and dysfunctional brain tissue metrics (regional damage or hypoperfusion in vascular territories) in two groups: participants with and without impaired single-word auditory comprehension. Hypoperfusion—particularly within …

Background: Some emergent large vessel occlusions (ELVOs) are refractory to reperfusion because of underlying intracranial atherosclerosis (ICAS), often requiring rescue therapy (RT) with balloon angioplasty, stenting, or both. In this study, we investigate the safety, efficacy, and long-term outcomes of RT in the setting of mechanical thrombectomy for ICAS-related ELVO.

Methods and Results: We queried the databases of 10 thrombectomy‐capable centers in North America and Europe included in STAR (Stroke Thrombectomy and Aneurysm Registry). Patients with ELVO who underwent ICAS‐related RT were included. A matched sample was produced for variables of age, admission National Institute of Health Stroke …


Measuring The Efficacy Of Medical Management Versus Decompressive Hemicraniectomy In Acute Stroke, Colton Hemphill, Franziska Herpich, Muhammad Athar, Eunice Lee Jan 2020

Measuring The Efficacy Of Medical Management Versus Decompressive Hemicraniectomy In Acute Stroke, Colton Hemphill, Franziska Herpich, Muhammad Athar, Eunice Lee

Phase 1

Introduction: Stroke is a life-threatening condition requiring immediate treatment in order to optimize patient survival and functionality post-hospitalization. At present, the primary treatment modalities used are intensive medical management and surgical decompressive hemicraniectomy. We believe that application of skilled medical management can result in a lower mortality rate and higher functional score at 12 months than aggressive surgical decompressive hemicraniectomy.

Methods: Epic data from Thomas Jefferson University will be used to identify patients with a large stroke (as defined by ischemic area on MRI) managed by the neurology department from 2016 to 2019. A survey will be administered by phone …

Optimizing the time it takes to get a potential stroke patient to imaging is essential in a rapid stroke response. At our hospital, door-to-imaging time is comprised of 2 time periods: the time before a stroke is recognized, followed by the period after the stroke code is called during which the stroke team assesses and brings the patient to the computed tomography scanner. To control for delays due to triage, we isolated the time period after a potential stroke has been recognized, as few studies have examined the biases of stroke code responders. This "code-to-imaging time" (CIT) encompassed the time …


Stress Induced Hyperglycemia In Stroke Patients, Aziz U Rehman, Ajeet Kumar, Salma Razzaque, Ashok Kumar, M. Ishaq Ghauri Jun 2015

Stress Induced Hyperglycemia In Stroke Patients, Aziz U Rehman, Ajeet Kumar, Salma Razzaque, Ashok Kumar, M. Ishaq Ghauri

Pakistan Journal of Neurological Sciences (PJNS)

Background:
Stroke is the third most common cause of death in developed countries and second most common cause of death worldwide. High proportion of patients may develop hyperglycemia after an acute stress such as stroke or myocardial infarction even in the absence of preexisting diagnosis of diabetes mellitus. Prolonged stress hyperglycemia in ischemic stroke increases the risk of in-hospital 28- day mortality, especially in non-diabetic patients.

Aims and objectives:
To determine the frequency of stress-induced hyperglycemia in non-diabetic patients with ischemic or hemorrhagic stroke.

Subjects and methods:
A total of 255 patients admitted with acute stroke, fulfilling the inclusion …

Cost Of Acute Stroke Care At A Tertiary Care Hospital In Karachi, Pakistan, B. A. Khealani, Z. F. Javed, N. A. Syed, Saad Shafqat, Mohammad Wasay Jan 2003

Cost Of Acute Stroke Care At A Tertiary Care Hospital In Karachi, Pakistan, B. A. Khealani, Z. F. Javed, N. A. Syed, Saad Shafqat, Mohammad Wasay

Section of Neurology

Objective:To evaluate cost of acute stroke care and its determinants at a tertiary care hospital in Karachi and to find out predictors of high cost care. Acute stroke is a leading cause of morbidity and mortality. Cost of care is the single most important determinant in availability of acute stroke care at a tertiary care hospital in Pakistan.It is also an important factor in development of public health policies and medical insurance plans. Average nnual income in Pakistan is 4881 rupees (U$ 85).
Methods: Medical and billing records of 443 patients with acute stroke were retrospectively reviewed from …
