<h3>Importance</h3> In atrial fibrillation (AF)–related acute ischemic stroke, the optimal oral anticoagulation strategy remains unclear. <h3>Objective</h3> To test whether rivaroxaban or warfarin sodium is safer and more effective for preventing early recurrent stroke in patients with AF-related stroke. <h3>Design, Setting, Participants</h3> A randomized, multicenter, open-label, blinded end point evaluation, comparative phase 2 trial was conducted from April 28, 2014, to December 7, 2015,...
Vestibular migraine (VM) is one of the most common causes episodic vertigo. We reviewed results multiple vestibular function tests in a cohort VM patients who were diagnosed with according to diagnostic criteria Barany Society and International Headache assessed efficacy each for predicting prognosis patients. A retrospective chart analysis was performed on 81 at tertiary care center from June 2014 July 2015. Patients by video head impulse test (vHIT), caloric test, vestibular-evoked...
Atrial fibrillation detected after stroke (AFDAS) refers to the identification of newly diagnosed atrial (AF) following an ischemic in patients without known AF (KAF). The objective this study was compare functional outcomes with AFDAS and those KAF who underwent mechanical thrombectomy.
To examine risk factors for posttreatment recurrence in papillary thyroid carcinoma (PTC) patients with initial presentation of lateral neck metastasis (N1b).N1b PTC recurs after definitive treatment.Study subjects were 437 consecutive who underwent total thyroidectomy and therapeutic dissection central compartments postoperative radioactive iodine ablation therapy. The patients' demographics pathological factors, including related to tumors lymph nodes (LNs), thyroglobulin levels reviewed....
The Gleason grading system, currently the most powerful prognostic predictor of prostate cancer, is based solely on tumor's histological architecture and has high inter-observer variability. We propose an automated scoring system deep neural networks for diagnosis core needle biopsy samples. To verify its efficacy, was trained using 1133 cases samples validated 700 cases. Further, system-based results were compared with reference standards derived from three certified pathologists. In...
Background and Objectives: Distal tibia fractures are high-energy injuries characterized by a mismatch between standard plate designs the patient’s specific anatomical bone structure, which can lead to severe soft tissue damage. Recent advancements have focused on development of customized metal plates using three-dimensional (3D) printing technology. However, 3D-printed titanium alloys not incorporated locking system due brittleness these alloys. Therefore, this study aimed determine...
Purpose: Several studies have examined the clinical impact of poststroke and stroke-related sarcopenia on stroke recovery. However, few investigated effect detected shortly after functional prognosis. We predicted outcomes using early screening for in patients with acute ischemic stroke. also Patients Methods: diagnosed within 2 days symptom onset were consecutively enrolled at a tertiary university hospital. Appendicular skeletal muscle mass (ASM) was measured dual-energy X-ray...
Abstract Background With the growing demand for use of thin perforator flaps, obtaining knowledge on superficial anatomy perforators is imperative stable flap elevation. Conventional modalities mapping fall short in providing such information. High‐frequency ultrasound (HFUS), known visualizing superficially located anatomic structures, may potentially fill this void. This study aimed to evaluate effectiveness HFUS outcome anterolateral thigh (ALT) and circumflex iliac artery (SCIP)...
Background and Purpose Decreasing the time delay for thrombolysis, including intravenous thrombolysis (IVT) with tissue plasminogen activator intra-arterial thrombectomy (IAT), is critical decreasing morbidity mortality of patients experiencing acute stroke. We aimed to decrease in-hospital both IVT IAT through a multidisciplinary approach that feasible 24 h/day. Methods implemented Stroke Alert Team (SAT) on May 2, 2016, which introduced hospital-initiated ambulance prenotification...
The exact pathophysiological mechanism of transient global amnesia (TGA) is unknown. It debatable whether TGA a risk factor for stroke. Therefore, here we investigated the possibility as stroke in real-world setting using large-scale nationwide health claims data.We used data from Korean National Health Insurance Service (NHIS). Patients diagnosed with between 2007 and 2013 were selected. We initially extracted patients without who preferentially matched age sex at ratio 10:1 whole dataset....
ABSTRACT The hippocampus plays critical roles in both object‐based event memory and spatial navigation, but it is largely unknown whether the left right hippocampi play functionally equivalent these cognitive domains. To examine hemispheric symmetry of human hippocampal functions, we used an fMRI scanner to measure BOLD activity while subjects performed tasks requiring navigation a virtual environment. Specifically, were required form object‐place paired associate after visiting four...
