BACKGROUND: Low 25-hydroxyvitamin D (25(OH)D) concentrations have been shown to predict risk of cardiovascular disease and all-cause mortality. Although the prevalence of 25(OH)D deficiency is high in patients with acute stroke, the prognostic value of 25(OH)D in stroke has not been clearly established. The purpose of this study was to determine whether the baseline serum 25(OH)D level was associated with the functional outcome in patients with acute ischemic stroke. METHODS: From June 2011 to J

BACKGROUND AND PURPOSE: The aim of this study was to determine the association between 25-hydroxyvitamin D (25(OH)D) and neuroimaging correlates of cerebral small vessel disease. METHODS: We identified 759 consecutive patients with acute ischemic stroke or transient ischemic attack. Lacunes, white matter hyperintensity, and cerebral microbleed (CMB) were assessed using MR images. Deep CMB was defined as the presence of CMB in basal ganglia, thalamus, or brain stem. The association between 25(OH)

Although subtle discourse declines in people with mild cognitive impairment (MCI) have been reported, heterogeneous measures and tasks among the MCI discourse studies have yielded widely varying outcomes. The present study aimed to first, identify discourse measures that aid the differentiation among people with amnestic MCI (aMCI), people with non-amnestic MCI (naMCI), and cognitively healthy control (HC) participants, and second, delineate the cognitive functions related to such discourse meas

ICAS is more prevalent than extracranial atherosclerosis among neurologically asymptomatic Korean adults. Subjects with ICAS are significantly older and have an increased frequency of hypertension compared to those subjects without atherosclerotic stenosis.

OBJECTIVES: We attempted to determine the propensity for sidedness of cardiogenic emboli associated with atrial fibrillation (AF) by comparing the sides on which microembolic signals (MES) were detected via transcranial Doppler (TCD) monitoring and the location of infarcts on magnetic resonance imaging. DESIGN: Patients with AF on Holter monitoring and MES on TCD monitoring were selected from an ischemic stroke registry. Patients with prosthetic valves or cerebral/carotid artery stenosis were ex

Contralateral soleus muscle atrophy occurs 21 days after establishing the Parkinson's disease rat model.

Typhlitis is a necrotizing enterocolitis of the cecum, ascending colon and terminal ileum. Typhlits has been reported in the severely neutropenic patients and likely results from a combination of neutropenia and defects in the bowel mucosa related to cytotoxic chemotherapy. This disease is most common in patients with leukemia who have undergone intensive myeloablative chemotherapy. Presumptive diagnostic criteria for typhlitis include fever, abdominal pain and tenderness, and radiologic evidenc

This study examines how the influence of the volume and rating of online reviews on consumer decision-making varies by self-construal. We predicted that the volume of reviews has a greater influence on decision making than the rating of reviews for those with interdependent self-construal people compared to those with independent people. In order to test the hypotheses, two experiments were conducted. In both experiments, we confirmed the results of similar patterns. In the first experiment, it
