Objective It is uncertain if patients with cardioembolic stroke and absence of a guidance-based indication for statin therapy should be administered a statin for prevention of subsequent vascular events. This study was performed to determine whether the statin therapy is beneficial to prevent major vascular events in this population. Methods Using a prospective multicenter stroke registry database, we identified acute cardioembolic stroke patients who were hospitalized between 2008 and 2015. Patients who had other established...

Data from: Pearls & Oy-sters: challenging diagnosis of Gerstmann-Sträussler-Scheinker disease: clinical and imaging findings

Min Ju Kang, Jeewon Suh, Seong Soo An, SangYun Kim & Young Ho Park
PEARLS >Gerstmann-Straussler-Scheinker disease (GSS) is a rare prion disease characterized by cerebellar ataxia with progressive cognitive decline. >GSS is caused by a mutation within the prion protein gene (PRNP), which commonly exhibits autosomal dominant inheritance pattern. However, a significant portion of previously reported cases showed no family history of the disease, and GSS may also occur through de novo mutation of PRNP. OY-STERS >GSS is clinically heterogeneous and has no characteristic features on imaging. GSS...

Objective: To improve epidemiological knowledge of neurological deterioration (ND) in patients with acute ischemic stroke (AIS). Methods: In this prospective observational study, we captured ND prospectively in 29,446 AIS patients admitted to 15 hospitals in Korea within 7 days of stroke onset. ND was defined as an increase in National Institutes of Health Stroke Scale (NIHSS) score ≥2 (total), or ≥1 (motor or consciousness), or any new neurological symptoms. Change of incidence rate after stroke...

Objective: Stroke is a devastating and costly disease; however, there is a paucity of information on long-term costs and on how they differ according to 3-month modified Rankin scale (mRS), which is a primary outcome variable in acute stroke intervention trials. Methods: We analyzed a prospective multicenter stroke registry (Clinical Research Collaboration for Stroke in Korea) database through linkage with claims data from the National Health Insurance Service with follow up to December 2016. Healthcare...

Wouter Jukema … & Perminder S Sachdev
OBJECTIVE: To address the variability in prevalence estimates and inconsistencies in potential risk factors for post-stroke cognitive impairment (PSCI) using a standardised approach and individual participant data (IPD) from international cohorts in the STROKOG consortium. METHODS: We harmonised data from thirteen studies based in eight countries. Neuropsychological test scores 2 to 6 months after stroke or TIA and appropriate normative data were used to calculate standardised cognitive domain scores. Domain-specific impairment was based on percentile...

Shaw
Objectives: To develop, demonstrate and evaluate an automated deep learning method for multiple cardiovascular structure segmentation. Background: Segmentation of cardiovascular images is resource-intensive. We design an automated deep learning method for the segmentation of multiple structures from Coronary Computed Tomography Angiography (CCTA) images. Methods: Images from a multicenter registry of patients that underwent clinically-indicated CCTA were used. The proximal ascending and descending aorta (PAA, DA), superior and inferior vena cavae (SVC, IVC), pulmonary artery (PA),...

Data from: Diagnostic performance of alpha-fetoprotein, protein induced by vitamin K absence, osteopontin, Dickkopf-1 and its combinations for hepatocellular carcinoma

Jang Eun Sun, Jeong Sook-Hyang, Kim Jin-Wook, Choi Yun Suk, Leissner Philippe, Brechot Christian, Eun Sun Jang, Sook-Hyang Jeong, Jin-Wook Kim & Yun Suk Choi
Background & Aims: Alpha-fetoprotein (AFP) is the most widely used serum biomarker for hepatocellular carcinoma (HCC), despite its limitations. As complementary biomarkers, protein induced by vitamin K absence (PIVKA-II), osteopontin (OPN), and Dickkopf-1 (DKK-1) have been proposed. This study aimed to perform a head-to-head comparison of the diagnostic performance of AFP, PIVKA-II, OPN and DKK-1 as single or in combination to seek the best biomarker or panel, and to investigate the clinical factors affecting their...

Data from: A novel cascade classifier for automatic microcalcification detection

Seung Yeon Shin, Soochahn Lee, Il Dong Yun, Ho Yub Jung, Yong Seok Heo, Sun Mi Kim & Kyoung Mu Lee
In this paper, we present a novel cascaded classification framework for automatic detection of individual and clusters of microcalcifications (μC). Our framework comprises three classification stages: i) a random forest (RF) classifier for simple features capturing the second order local structure of individual μCs, where non-μC pixels in the target mammogram are efficiently eliminated; ii) a more complex discriminative restricted Boltzmann machine (DRBM) classifier for μC candidates determined in the RF stage, which automatically learns...

Idiopathic normal pressure hydrocephalus with synucleinopathy: diagnosis and treatment

Young Ho Park, Sang-Won Han, Nayoung Ryoo, Kitae Kim, Jung-Min Pyun & SangYun Kim
Pearls - Idiopathic normal pressure hydrocephalus (iNPH) is characterized by the classic triad of gait disturbance, urinary incontinence, and cognitive impairment in the presence of ventriculomegaly without known risk factors for communicating hydrocephalus. Shunt surgery is indicated for iNPH patients who respond to the removal of CSF. Oy-sters - The striatal dopaminergic deficit on dopamine transporter (DAT) scan is not uncommon in patients with iNPH, which might be related to an unfavorable long-term outcome of...
