Xiang Hu, Chi Zhang
Radical surgery of gastric cancer (D2 lymph node dissection) as the standard operation is widely used in clinical practice and satisfactory prognosis can be obtained in patients who receive radical gastrectomy. But surgical invasion can cause high morbidity of complications and mortality. The data of large-scale evidence-based medical clinical trials and large databases in Japan and Korea showed that anastomotic leakage, pancreatic leakage and abdominal abscess were the most common complications after gastrectomy, and the morbidity of complication was about 20% and mortality was about 1%...

BACKGROUND: To characterize the temporal dynamics of mumps epidemiology according to different vaccine strains used, we decomposed gender-specific trends in an age-period-cohort (APC) analysis for mumps cases reported in South Korea. METHODS: We used the national surveillance data to describe the epidemiology of mumps cases from 2001 to 2015. An APC model was used to break down the reported mumps cases into the effects of age, period, and birth cohort. RESULTS: From 2001 to 2015, the incidence started to increase from fewer than 10 cases to more than 100 cases per 100,000...

INTRODUCTION: The identification of small (<2 cm) gastrointestinal stromal tumors (GISTs) is increasingly recognized. The malignancy potential is not absent. However, data on risk is scarce. The aim was to review the existing data on perceived risk of small GISTs in population-based studies. METHODS: A combined review of small GISTs (<2 cm) in a population-based dataset compared with a systematic review of available population-based studies. RESULTS: About one in every four (27%) patient has a small GIST, of which 79% were incidental in presentation, and all had a low-risk mitoses index (<5/hpf)...

A novel aerobic, non-motile, halotolerant, alkalitolerant, hydrocarbon degrading, and rod shaped bacterium, designated strain R160(T), was isolated from soil in South Korea. Cells were Gram-staining-negative, catalase-positive, and oxidase-negative. This strain grew up to 7% of NaCl and in the pH range of 6-11 (optimum 7.0-10.0). The isolate degraded 51.7 ± 1.3% of hydrocarbon components (C-18, C-20, and C-22) and 45.8 ± 1.4% oil components (kerosene, diesel, and gasoline). Phylogenetic analysis based on 16 S rRNA gene sequences revealed that strain R160(T) formed a lineage within the genus Acinetobacter, and was closely related to 'Acinetobacter oleivorans' DR1(T) (97...
