Does colonization with methicillin-susceptible Staphylococcus aureus protect against nosocomial acquisition of methicillin-resistant S. aureus?
To test the hypothesis that methicillin-susceptible Staphylococcus aureus (MSSA) carriage may protect against nosocomial methicillin-resistant S. aureus (MRSA) acquisition by competing for colonization of the anterior nares. ⋯ Endogenous MSSA colonization does not appear to protect against nosocomial MRSA acquisition in a population of medical patients without frequent antibiotic exposure.

Multidrug-resistant gram-negative bloodstream infections among residents of long-term care facilities.
Prevalence of multidrug-resistant (MDR) gram-negative (GN) bacteria is increasing globally and is complicated by patient movement between acute and long-term care facilities (LTCFs). In Asia, the contribution of LTCFs as a source of MDR GN infections is poorly described. We aimed to define the association between residence in LTCFs and MDR GN bloodstream infections (BSIs). ⋯ Residence in a LTCF is an independent risk factor for MDR GN BSI. Attempts to contain MDR GN bacteria in large Asian cities, where the proportion of the population that is elderly is projected to increase, should include infection prevention strategies that engage LTCFs.

Descriptive epidemiology and attributable morbidity of ventilator-associated events.
The Centers for Disease Control and Prevention implemented new surveillance definitions for ventilator-associated events (VAEs) in January 2013. We describe the epidemiology, attributable morbidity, and attributable mortality of VAEs. ⋯ VAEs are common and morbid. Prevention strategies targeting VAEs are needed.

Comparative StudyComparison of laboratory-confirmed influenza and noninfluenza acute respiratory illness in healthcare personnel during the 2010-2011 influenza season.
Compare the severity of illnesses associated with influenza and noninfluenza acute respiratory illness (ARI) in healthcare personnel (HCP). ⋯ Influenza had a greater negative impact on HCP than noninfluenza ARIs, indicated by higher symptom severity scores, less ability to perform activities of daily living, and more missed work. These results highlight the importance of efforts to prevent influenza infection in HCP.
