Recovery of Bi and Sb from Copper Spent Electrolytes by Electrowinning Method.

The consumption of rare metals from the industrial development has been increasing despite of unstable and limited rare metals supply. Copper electrolyte after copper electrorefining contains 200-300 mg/L of bismuth (Bi) and antimony (Sb). Bi and Sb were recovered through electrowinning of electrochemical method.

Prevalence of renal dysfunction in patients with cirrhosis according to ADQI-IAC working party proposal.

Background/aims: A revised classification system for renal dysfunction in patients with cirrhosis was proposed by the Acute Dialysis Quality Initiative and the International Ascites Club Working Group in 2011. The aim of this study was to determine the prevalence of renal dysfunction according to the criteria in this proposal.

Methods: The medical records of cirrhotic patients who were admitted to Konkuk University Hospital between 2006 and 2010 were reviewed retrospectively.

The Refit model for end-stage liver disease-Na is not a better predictor of mortality than the Refit model for end-stage liver disease in patients with cirrhosis and ascites.

Background/aims: The modification of the Model for End-Stage Liver Disease (MELD) scoring system (Refit MELD) and the modification of MELD-Na (Refit MELDNa), which optimized the MELD coefficients, were published in 2011. We aimed to validate the superiority of the Refit MELDNa over the Refit MELD for the prediction of 3-month mortality in Korean patients with cirrhosis and ascites.

Methods: We reviewed the medical records of patients admitted with hepatic cirrhosis and ascites to the Konkuk University Hospital between January 2006 and December 2011.

Elevated hemoglobin A1c levels are associated with worse survival in advanced pancreatic cancer patients with diabetes.

Background/aims: Pre-existing diabetes mellitus (DM) has been identified as an adverse prognostic variable associated with increased mortality in various cancers. Although DM and hyperglycemia are considered risk factors for pancreatic cancer (PC), antidiabetic treatments for patients with advanced PC have been overlooked. This study aimed to evaluate the impact of hemoglobin A1c (HbA1c) levels on PC survival.

Predictive value of Refit Model for End-Stage Liver Disease, Refit Model for End-Stage Liver Disease-Na, and pre-existing scoring system for 3-month mortality in Korean patients with cirrhosis.

Background And Aim: The Model for End-Stage Liver Disease (MELD) has been widely used for predicting short-term mortality in patients with cirrhosis in the U.S. A modification of the MELD score was published in 2011.

Simultaneous total occlusion of multiple distal coronary arteries in acute myocardial infarction.

Simultaneous multiple coronary artery thrombosis is a rare finding in ST segment elevation myocardial infarction (STEMI). We report a case of myocardial infarction with multiple ST segment elevation on the electrocardiography and total occlusions of the distal left anterior descending artery (dLAD), as well as of the second and third obtuse marginal artery on emergency coronary angiography. Thrombus aspiration was performed at dLAD and systemic glycoprotein IIb/IIIa inhibitor was used successfully.
