RESUMEN
BACKGROUND AND AIM: Dietary factors are closely associated with the risk of non-alcoholic fatty liver disease (NAFLD). Asian and Western diets differ in energy-nutrient composition, fatty-acid composition, and main nutritional sources; therefore, the implications would be limited if the Western-oriented study results were applied to Asian patients. We aimed to identify the nutrient and food group intakes of a typical Asian diet and assess their effects on NAFLD risk. METHODS: In total, 348 subjects were recruited from 5 participating hospitals. Information on sociodemographic characteristics and health-related behaviors were obtained through face-to-face interviews. NAFLD was diagnosed by ultrasound. Dietary intakes were assessed with a 24-h recall applying a multiple-pass approach and 4-day food records that included 1 or 2 weekend days. RESULTS: There were no significant differences in health-related behaviors between the cases and controls except for smoking behavior. The cases had elevated triacylglycerol, fasting glucose, and low-density lipoprotein cholesterol levels compared with the controls. In men, after adjusting for variables, low intakes of vitamin C (odds ratio [OR], 4.23), vitamin K (OR, 3.93), folate (OR, 3.37), omega-3 fatty acids (OR, 2.16), and nuts and seeds (OR, 3.66) were associated with a significantly higher risk for developing NAFLD. In women, vitamin K (OR, 2.54) and vegetable (OR, 4.11) intakes showed a significant beneficial effect for lowering NAFLD risk. CONCLUSIONS: Adequate intakes of vitamin C, vitamin K, folate, omega-3 fatty acids, nuts and seeds, and vegetables may help in preventing NAFLD in Korean adults.

Lead is a neurotoxin that affects the developing central nervous system and may potentially induce apoptotic cell death. We investigated the effect of ascorbic acid against lead-induced neurotoxicity in the developing rat hippocampus. Female Sprague-Dawley rats were divided into three groups: control group, lead-treated group and lead plus ascorbic acid-treated group. Lead (0.2% lead acetate) was administered to female rats during pregnancy and lactation, in their drinking water. During this period, rats in the lead plus ascorbic acid-treated group received 100 mg/kg/day ascorbic acid, orally. At the end of the treatment, neuronal damage, apoptosis and blood lead levels were determined and the levels of Bax and Bcl-2 were immunodetected in the hippocampus of 21-day-old male pups. Histopathological evaluation demonstrated that ascorbic acid significantly attenuates apoptosis in the developing hippocampus and also spares hippocampal CA1, CA3 and dentate gyrus (DG) neurons. Simultaneous administration of ascorbic acid and lead lowered the level of Bax protein and increased Bcl-2 in pup hippocampus and reduced lead level in blood of dams compared with lead-treated only. Based on these results, it seems that ascorbic acid may potentially be beneficial in treating lead-induced brain injury in the developing rat brain.

OBJECTIVES: This study evaluated the qualitative and quantitative performances of the newly developed information system which was implemented on November 4, 2011 at the National Health Insurance Corporation Ilsan Hospital. METHODS: Registration waiting time and changes in the satisfaction scores for the key performance indicators (KPI) before and after the introduction of the system were compared; and the economic effects of the system were analyzed by using the information economics approach. RESULTS: After the introduction of the system, the waiting time for registration was reduced by 20%, and the waiting time at the internal medicine department was reduced by 15%. The benefit-to-cost ratio was increased to 1.34 when all intangible benefits were included in the economic analysis. CONCLUSIONS: The economic impact and target satisfaction rates increased due to the introduction of the new system. The results were proven by the quantitative and qualitative analyses carried out in this study. This study was conducted only seven months after the introduction of the system. As such, a follow-up study should be carried out in the future when the system stabilizes.
RESUMEN
Lymphangioleiomyomatosis is a rare disease that is characterized by proliferation of abnormal smooth muscle-like cells, especially that which occurs in the pulmonary parenchyme. It primarily affects women of child-bearing age. The majority of primary lymphangioleiomyomatosis occurs in the lung, but there are a few reports of extrapulmonary cases. We experienced a rare case of lymphangioleiomyomatosis which originated in the pelvic cavity (in the posterior portion of the uterus), and report with brief review of literatures.
