Prevalence, persistence, and microbiology of XXXX nasal carriage among hemodialysis outpatients at a major New York Hospital.

@entity1 @entity3256 @entity2176 @entity794 @entity645 @entity6252
The study aimed to determine the natural history of @entity794 nasal colonization in hemodialysis outpatients. Surveillance cultures were taken from @entity1 presenting for hemodialysis or routine care to identify @entity794 nasal carriers. A prospective cohort study was performed to identify risks for persistent colonization. Detailed microbiologic and molecular studies of colonizing isolates were performed. Only 23/145 (15.9%) dialysis @entity1 were persistently colonized, and only @entity645 -positive status was associated with persistence (P = 0.05). Prior hospitalization was the only risk factor for @entity3256 -resistant @entity794 carriage (OR 2.5, P = 0.03). In isolates from @entity1 with  <= 42 days of @entity2176 exposure, @entity2176 @entity6252 ( @entity6252 ) increased with duration of exposure. Among dialysis @entity1 , @entity794 colonization was limited and transient; only @entity645 status was associated with persistence. Nevertheless, duration of @entity2176 exposure was associated with increasing @entity2176 @entity6252 . @entity2176 exposure in @entity794 carriers may be involved in increasing resistance.
