Quynh Doan,Hubert Wong,Garth Meckler,David W. Johnson,Antonia S Stang,Andrew Dixon,Scott Sawyer,Tania Principi,April J. Kam,Gary Joubert,Jocelyn Gravel,Mona Jabbour,Astrid Guttmann +12 more
TL;DR: Emergency department crowding was not significantly associated with hospital admission within 7 days of the emergency department visit or mortality in children, however, it was associated with increased hospital admission at the index visit for the sickest children, and with return visits to theEmergency department for those less sick.
Journal ArticleDOI

Karen A. Herzig,Helen G. Juffs,Debra Norris,Allison M. Brown,Devinder Gill,Carmel M. Hawley,Ralph Cobcroft,James J.B. Petrie,Paula Marlton,Damien Thomson,Scott B. Campbell,David Nicol,David W. Johnson +12 more
TL;DR: It is concluded that PTLD is more likely, occurs earlier, and is more often fatal, in the setting of intensive immunosuppression, and excellent long-term outcomes are achievable with early recognition and institution of appropriate treatment.
Journal ArticleDOI
The relationship of a clonal outbreak of Enterococcus faecium vanA to methicillin-resistant Staphylococcus aureus incidence in an Australian hospital
Paul B. Bartley,Jacqueline Schooneveldt,David Looke,Anthony Morton,David W. Johnson,Graeme R. Nimmo +5 more
TL;DR: Australian isolates of vancomycin-resistant enterococci (VRE) have been widely scattered geographically, predominantly polyclonal and of the VanB phenotype, and have the ability to influence the epidemiology of other nosocomial pathogens when infection control resources are exhausted.
Journal ArticleDOI
Free amino acid quantification by LC-MS/MS using derivatization generated isotope-labelled standards.
TL;DR: In this paper, the succinimide ester of 4-methylpiperazineacetic acid (MPAS), the iTRAQ reagent, was systematically modified to improve tandem mass spectrometer (MS/MS) product ion intensity.
