This study sought to determine a mortality prediction model that could be used for triage in the setting of acute hemorrhage from trauma. To achieve this aim, various machine learning techniques were applied using the rat model in acute hemorrhage. Thirty-six anesthetized rats were randomized into three groups according to the volume of controlled blood(More)
—Efficient service description and modeling methodologies are essential for dynamic service composition to provide autonomous services for users in ubiquitous computing environments. In our previous research, we proposed a 'u-service' ontology which is an abstract and structured concept for device operations in ubiquitous environments. One of the problems(More)
Recently, MET exon 14 deletion (METex14del) has been postulated to be one potential mechanism for MET protein overexpression. We screened for the presence of METex14del transcript by multiplexed fusion transcript analysis using nCounter assay followed by confirmation with quantitative reverse transcription PCR with correlation to MET protein expression by(More)
The aims of this study were to evaluate the clinicopathologic features of Helicobacter heilmannii-associated gastritis and to compare H. heilmannii-associated gastritis with H. pylori-associated gastritis. We reviewed 5,985 consecutive gastric biopsy specimens. All cases of chronic gastritis with Helicobacter infection were evaluated with the Updated Sydney(More)
Primary biliary cirrhosis (PBC) is a slowly progressive cholestatic liver disease of autoimmune etiology. The initial presentation of PBC is various from asymptomatic, abnormal liver biochemical tests to overt cirrhosis. The diagnosis of PBC is based on cholestatic biochemical liver tests, presence of antimitochondrial antibody and histologic findings of(More)
BACKGROUND/AIMS This study investigated the antiviral effects of tenofovir disoproxil fumarate (TDF) monotherapy in nucleos(t)ide analogue (NA)-naive and NA-experienced chronic hepatitis B (CHB) patients. METHODS CHB patients treated with TDF monotherapy (300 mg/day) for ≥12 weeks between December 2012 and July 2014 at a single center were retrospectively(More)
BACKGROUND/AIMS Deterioration of renal function in cirrhotic patients with spontaneous bacterial peritonitis (SBP) is a predictor for in-hospital mortality; however, the clinical significance of renal dysfunction during bacterial infection other than SBP is unknown. The aim of this study was to investigate the prevalence and clinical significance of renal(More)
BACKGROUND/AIMS Dilutional hyponatremia associated with liver cirrhosis is caused by impaired free water clearance. Several studies have shown that serum sodium levels correlate with survival in cirrhotic patients. Little is known, however, regarding the relationship between the degree of dilutional hyponatremia and development of cirrhotic complications.(More)
BACKGROUND/AIMS Many patients are diagnosed with cryptogenic hepatocellular carcinoma (HCC) without metabolic syndrome (MS). We investigated the risk factors for cryptogenic HCC in patients with a low body mass index (BMI) or without MS. METHODS Thirty-six patients were diagnosed with cryptogenic HCC over a 10-year period at a tertiary research hospital.(More)
