Purpose: To retrospectively evaluate the diagnostic accuracy of ultrasonographic (US) criteria for depiction benign and malignant thyroid nodules by using tissue diagnosis as reference standard. Materials Methods: This study had institutional review board approval, informed consent was waived. From January 2003 through June 2003, 8024 consecutive patients undergone US at nine affiliated hospitals. A total 831 (716 women, 115 men; mean age, 49.5 years ± 13.8 [standard deviation]) with 849...
Background and Purpose— Effective rescue treatment has not yet been suggested in patients with mechanical thrombectomy (MT) failure. This study aimed to test whether stenting (RS) improved clinical outcomes MT-failed patients. Methods— is a retrospective analysis of the cohorts 16 comprehensive stroke centers between September 2010 December 2015. We identified who underwent MT but failed recanalize intracranial internal carotid artery or middle cerebral M1 occlusion. Patients were...
Background Multicenter studies may be required for establishing guidelines safe usage of iodinated contrast media (ICM). Purpose To identify the prevalence, patterns, risk factors, and preventive measures ICM-related hypersensitivity reactions (HSRs). Materials Methods Between March 2017 October 2017, a total 196 081 patients who underwent ICM administration were enrolled from seven participating institutions. The occurrence HSRs baseline patient information recorded. χ2 Student t test...
Background and Purpose— Stent retriever (SR) thrombectomy has become the mainstay of treatment acute intracranial large artery occlusion. However, it is still not much known about optimal limit SR attempts for favorable outcome. We evaluated whether a specific number passes futile recanalization can be determined. Methods— Patients who were treated with as first endovascular modality their occlusion in anterior circulation retrospectively reviewed. The rate each pass was calculated....
Objective To characterise the time window in which endovascular thrombectomy (EVT) is associated with good outcome, and to test differential relationship between functional outcome onset-to-reperfusion (ORT), depending on collateral status. Methods This was a retrospective analysis of clinical imaging data 554 consecutive patients, who had recanalisation success by EVT for anterior circulation large artery occlusion, from prospectively maintained registries 16 comprehensive stroke centres...
Our aim was to investigate the distribution pattern of cerebral artery calcification and its association with white matter hyperintensities (WMH).We identified 159 consecutive patients acute ischemic stroke. Calcifications arteries WMH were graded.Cerebral found in 137 (86.2%). The intracranial internal carotid (I-ICA) most frequently affected (76.7%) moderate-to-severe (38.1%). Spearman's rank test revealed that grade I-ICA correlated those periventricular (r = 0.417, p < 0.001) deep 0.388,...
The purpose of this study was to assess the safety and early outcomes Pipeline device for large/giant or fusiform aneurysms.The implanted in a total 45 patients (mean age, 58 years; M:F=10:35) with 47 aneurysms. We retrospectively evaluated characteristics treated aneurysms, periprocedural events, morbidity mortality, after implantation.The aneurysms were located internal carotid artery (ICA) cavernous segment (n=25), ICA intradural (n=11), vertebrobasilar trunk (n=8), middle cerebral (n=3)....
Purpose To assess patient radiation doses during cerebral angiography and embolization of intracranial aneurysms across multi-centers propose a diagnostic reference level (DRL). Materials Methods We studied sample 490 371 therapeutic procedures for aneurysms, which were performed at 23 hospitals in Korea 2015. Parameters including dose-area product (DAP), cumulative air kerma (CAK), fluoroscopic time total angiographic image frames obtained analyzed. Results Total mean DAP, CAK, fluoroscopy...
Probiotics have been shown to enhance cognitive function in individuals with mild impairment (MCI), but their efficacy varies, depending on the strain and dosage. Clinical investigations are crucial confirm safety, efficacy, mechanism of action. This study was designed assess effective dosage, MH-Pro, a test product containing Lacticaseibacillus rhamnosus CBT-LR5 (LR5) skim milk (non-fat dry milk), improving related physiological changes older adults suspected MCI over 12 weeks. In total, 20...
In this study, a Multi-Sensor IoT Device (MSID) is developed that designed to collect various environmental data and interconnect with the cloud blockchain ensure reliable management. The MSID flexible, modular structure supports variety of sensor configurations easily expandable 3D-printed components. system performance was monitored in real-time, high upload success rate 98.35% an average transmission delay only 0.64 s, confirming stable collection every minute. Blockchain-based storage...
Background and purpose The prognostic value of contrast accumulation from non‐contrast brain computed tomography taken immediately after endovascular reperfusion treatment in acute ischaemic stroke patients to predict symptomatic hemorrhage was studied. Methods Between July 2007 August 2014, anterior circulation who were treated by intra‐arterial thrombolysis or thrombectomy included. Contrast defined as a high attenuation area treatment, categorized into three groups according the presence...
This study aimed to evaluate the hypotheses that administration routes [intra-arterial (IA) vs. intravenous (IV)] affect early stage migration of transplanted human bone marrow-derived mesenchymal stem cells (hBM-MSCs) in acute brain infarction.Male Sprague-Dawley rats (n=40) were subjected photothrombotic infarction. Three days after infarction, randomly allocated one four experimental groups [IA group : n=12, IV superparamagnetic iron oxide (SPIO) n=8, control n=8]. All subdivided into 1,...
Inflammatory bowel disease (IBD) is a severe immune cell-mediated syndrome characterised by extensive inflammatory and effector mucosal responses leading to tissue destruction in the colon small intestine. The hypothesis that dysbiosis of gut flora causes an excessive response inflammation gastrointestinal track. Lactic acid bacteria (LAB) can correct normal microbiota. In current study, therapeutic potential seven LAB strains combination treat IBD was evaluated using experimental colitis...
Recent studies suggest that thrombus imaging characteristics such as Hounsfield unit (HU) and perviousness assessed on noncontrast computed tomography (NCCT) CT angiography (CTA) can predict successful recanalization. We whether these could first-pass recanalization.We retrospectively reviewed cases of mechanical thrombectomy over a three-year period in which patients received multiphase CTA were treated with stent retriever first pass. Thrombus attenuation, enhancement arterial-...
Abstract BACKGROUND It remains controversial whether carotid artery stenting (CAS) is needed in cases of tandem cervical internal occlusion (cICAO) and intracranial large vessel (LVO). OBJECTIVE To investigate the efficacy safety CAS combination with endovascular thrombectomy (CAS-EVT) cICAO-LVO patients to compare its outcomes those EVT without (EVT-alone). METHODS We identified all who underwent for from prospectively maintained registries 17 stroke centers. Patients were classified into 2...
To compare the use of 3D driven equilibrium (DRIVE) imaging with balanced fast field echo (bFFE) in assessment anatomic structures internal auditory canal (IAC) and inner ear at 3 Tesla (T).Thirty ears 15 subjects (7 men 8 women; age range, 22-71 years; average age, 50 years) without evidence problems were examined on a whole-body 3T MR scanner both DRIVE bFFE sequences by using an 8-channel sensitivity encoding (SENSE) head coil. Two neuroradiologists reviewed images particular attention to...
