Practice of parenteral nutrition in hospitalized adult patients in Korea: A retrospective multicenter cross-sectional study.

There have been no studies on the characteristics of parenteral nutrition (PN) supply for adult inpatients in South Korea. The aim of this retrospective multicenter cross sectional study was to investigate the current practice and characteristics of PN support in hospitalized adult patients in South Korea for the first time. This study was conducted retrospectively for the adult patients who were hospitalized and received PN in nine hospitals on August 1st, 2017 to October 30th, 2017.

Effects of Citrulline Supplementation on Body Weight in Patients With Hepatobiliary Pancreatic Surgery.

Background: Many health benefits have been proposed for citrulline, but they lack evidence based on human research. This study was to evaluate whether an oral citrulline supplement affects body weight changes and laboratory values in patients with hepatobiliary and pancreatic surgery.

Methods: Patients who underwent hepatobiliary and pancreatic surgery during January to June 2015 were screened for analysis.

Epidemiological and genetic characterization of methicillin-resistant Staphylococcus aureus isolates from the ear discharge of outpatients with chronic otitis media.

The origin of methicillin-resistant Staphylococcus aureus (MRSA) strains from otolaryngology outpatients has not been evaluated yet in Korea. We analyzed epidemiologic and genetic characteristics of MRSA isolates from the ear discharge of 64 outpatients with chronic otitis media in a Korean University Hospital during 2004. MRSA strains were grouped as either from the initial visit (n=33) or the follow-up visit (n=31) based on the timing of isolation.

Molecular analysis of isoleucyl-tRNA synthetase mutations in clinical isolates of methicillin-resistant Staphylococcus aureus with low-level mupirocin resistance.

Emergence and spread of low-level mupirocin resistance in staphylococci have been increasingly reported in recent years. The aim of this study was to characterize missense mutations within the chromosomal isoleucyl-tRNA synthetase gene (ileS) among clinical isolates of methicillin-resistant Staphylococcus aureus (MRSA) with low-level mupirocin resistance. A total of 20 isolates of MRSA with low-level mupirocin resistance (minimal inhibitory concentration, 16-64 microg/mL) were collected from 79 patients in intensive care units for six months.

Risk factors for isolation of low-level mupirocin-resistant versus -susceptible methicillin-resistant Staphylococcus aureus from patients in intensive care units.

Objectives: The aim of this study was to determine the risk factors for the recovery of low-level mupirocin-resistant (mup(r)) or -susceptible (mup(s)) MRSA from patients in intensive care units (ICUs).

Methods: A case-case-control study was conducted from November 2003 to April 2004. Two case groups consisted of patients with low-level mup(r) MRSA and mup(s) MRSA.

Shielding analysis at the upper section of the accelerator-driven system.

The proton beam duct of the accelerator-driven system (ADS) acts as a streaming path for spallation neutrons and photons and causes the activation of the magnets and other devices above the subcritical core. We have performed a streaming analysis at the upper section of the lead-bismuth target/cooled ADS (800 MWth). MCNPX was used to calculate the radiation dose from streamed neutrons and photons through the beam duct.

Novel PCR-restriction fragment length polymorphism analysis for rapid typing of staphylococcal cassette chromosome mec elements.

We developed a novel PCR-restriction fragment length polymorphism test for the ccrB gene by using HinfI and BsmI for rapid typing of staphylococcal cassette chromosome mec (SCCmec). When tested with reference strains and methicillin-resistant Staphylococcus aureus isolates, the method proved to be valid and useful for rapid identification of four SCCmec types, especially type IV.
