METHODS: We conducted a prospective observational study of all episodes of bacteremic, community-onset, and radiologically confirmed pneumonia due to Acinetobacter species at a tertiary referral hospital in tropical Australia from 1997 to 2012 following the introduction of routine empirical treatment protocols covering Acinetobacter. Demographic, clinical, microbiologic, and outcome data were collected. RESULTS: There were 41 episodes of bacteremic community-onset Acinetobacter pneumonia, of which 36 had no indicators suggesting health-care-associated infection. Of these, 38 (93%) were Indigenous Australians, one-half were men, the average age was 44.1 years, and 36 episodes (88%) occurred during the rainy season. All patients had at least one risk factor, with hazardous alcohol intake in 82%. Of the 37 isolates available for molecular speciation, 35 were Acinetobacter baumannii and two were Acinetobacter nosocomialis. All isolates were susceptible in vitro to gentamicin, meropenem, and ciprofloxacin, but only one was fully susceptible to ceftriaxone. ICU admission was required in 80%. All 41 patients received appropriate antibiotics within the first 24 h of admission, and 28- and 90-day mortality were both low at 11%. CONCLUSIONS: Community-acquired Acinetobacter pneumonia is a severe disease, with the majority of patients requiring ICU admission. Most patients have risk factors, particularly hazardous alcohol use. Despite this severity, correct initial empirical antibiotic therapy in all patients was associated with low mortality.]]> Sun 21 Jun 2015 17:37:28 AEST ]]> Effect of a sun protection intervention on the immune response to measles booster vaccination in infants in rural South Africa https://nova.newcastle.edu.au/vital/access/ /manager/Repository/uon:36054 -1 which was considered the protective antibody concentration. There was no statistically significant difference in titers between groups: geometric difference in mean titers 1.13 mIU mL-1 (95% CI 0.85, 1.51; P = 0.39) and 1.38 mIU mL-1 (95% CI 0.90, 2.11, P = 0.14) for unadjusted and adjusted analyses, respectively. This study demonstrated that a sun protection intervention study could be performed in a developing-world pediatric vaccination setting. Although the sun protection intervention around the time of vaccination was not associated with a higher antibody level, given the potential importance of such an effect, a larger study should be considered.]]> Fri 03 Dec 2021 10:35:33 AEDT ]]>
