TL;DR: The results highlight the importance of antibiotic stewardship and the thoughtful use of medical devices in helping prevent outbreaks of carbapenem-resistant P. aeruginosa.
Abstract: A systematic review and meta-analyses were performed to identify the risk factors associated with carbapenem-resistant Pseudomonas aeruginosa and to identify sources and reservoirs for the pathogen. A systematic search of PubMed and Embase databases from 1 January 1987 until 27 January 2012 identified 1,662 articles, 53 of which were included in a systematic review and 38 in a random-effects meta-analysis study. The use of carbapenem, use of fluoroquinolones, use of vancomycin, use of other antibiotics, having medical devices, intensive care unit (ICU) admission, having underlying diseases, patient characteristics, and length of hospital stay were significant risk factors in multivariate analyses. The meta-analyses showed that carbapenem use (odds ratio [OR] = 7.09; 95% confidence interval [CI] = 5.43 to 9.25) and medical devices (OR = 5.11; 95% CI = 3.55 to 7.37) generated the highest pooled estimates. Cumulative meta-analyses showed that the pooled estimate of carbapenem use was stable and that the pooled estimate of the risk factor "having medical devices" increased with time. We conclude that our results highlight the importance of antibiotic stewardship and the thoughtful use of medical devices in helping prevent outbreaks of carbapenem-resistant P. aeruginosa.

TL;DR: The limited coverage of commercially available vaccines against the serotypes found in this population, and the high proportion of non-susceptibility to penicillin and cotrimoxazol suggest the need for region-specific information and strategies to control S. pneumoniae in Indonesia.
Abstract: INTRODUCTION: Streptococcus pneumoniae is a worldwide occurring pathogen Nasopharyngeal carriage of Streptococcus pneumoniae precedes pneumonia and other pneumococcal diseases in the community. Little is known about S. pneumoniae carriage in Indonesia, complicating strategies to control pneumococcal diseases. We investigated nasopharyngeal carriage of S. pneumoniae in Semarang, Indonesia. METHODS: A population-based survey was performed in Semarang, Indonesia. Nasopharyngeal swabs and questionnaires were taken from 496 healthy young (6-60 month-old) children and 45-70 year-old adults. RESULTS: Forty-three percent of children aged 6-60 months and 11% of adults aged 45-75 years carried S. pneumoniae. Determinants of carriage were being a child (OR 7.7; 95% CI = 4.5-13.0), passive smoking (OR 2.1; 95% CI = 1.3-3.4), and contact with toddler(s) at home (OR 3.0; 95% CI = 1.9-4.7). The most frequent serotypes found were 6A/B and 15B/C. The current commercially available vaccines cover <50% serotypes found in children. Twenty-four percent of S. pneumoniae strains were penicillin non-susceptible, and 45% were resistant to cotrimoxazol. CONCLUSIONS: The limited coverage of commercially available vaccines against the serotypes found in this population, and the high proportion of non-susceptibility to penicillin and cotrimoxazol suggest the need for region-specific information and strategies to control S. pneumoniae.

TL;DR: MRSA and PVL-positive MSSA are present among patients in surgical wards in Indonesian academic hospitals, according to the epidemiology of S. aureus among surgery patients in three academic hospitals in Indonesia.
Abstract: Data of Staphylococcus aureus carriage in Indonesian hospitals are scarce. Therefore, the epidemiology of S. aureus among surgery patients in three academic hospitals in Indonesia was studied. In total, 366 of 1,502 (24.4%) patients carried S. aureus. The methicillin-resistant S. aureus (MRSA) carriage rate was 4.3%, whereas 1.5% of the patients carried Panton-Valentine leukocidin (PVL)-positive methicillin-sensitive S. aureus (MSSA). Semarang and Malang city (odds ratio [OR] 9.4 and OR 9.0), being male (OR 2.4), hospitalization for more than 5 days (OR 11.708), and antibiotic therapy during hospitalization (OR 2.6) were independent determinants for MRSA carriage, whereas prior hospitalization (OR 2.5) was the only one risk factor for PVL-positive MSSA carriage. Typing of MRSA strains by Raman spectroscopy showed three large clusters assigned type 21, 24, and 38, all corresponding to ST239-MRSA-SCCmec type III. In conclusion, MRSA and PVL-positive MSSA are present among patients in surgical wards in Indonesian academic hospitals.

TL;DR: It is suggested that carbapenemase-producing Enterobacteriaceae are probably more prevalent in Curacao than previously recognized.
Abstract: Background: Although the presence of Carbapenemase-producing Enterobacteriaceae (CPE) are extensively documented in North and South America. CPE have not been reported from Curacao. However, recently intercontinental spread was suggested of a KPC carbapenemase producing Klebsiella pneumoniae in a patient in the United Kingdom with previous admission to a hospital in Curacao in 2009. Findings: After the introduction of the CLSI 2010 revised breakpoints, seven patients with carbapenemase-producing Enterobacteriaceae were found in a general hospital in Curacao over a period of 16 months. Four patients carried KPC-2 positive Klebsiella pneumoniae, ST11. Two patients carried KPC-3 positive Klebsiella pneumoniae ST258 and one patient carried a KPC-3 positive Citrobacter freundii. Furthermore, our Klebsiella pneumoniae KPC-2 ST11 strain was matched to the Klebsiella pneumoniae KPC-2 ST11 strain in the United Kingdom. Conclusions: Introduction of new laboratory methods, and adoption of new guidelines and breakpoints led to the first detection of CPE in Curacao. By matching our Klebsiella pneumoniae KPC-2 ST11 strain to a Klebsiella pneumoniae KPC-2 ST11 strain in the United Kingdom, we suggest that carbapenemase-producing Enterobacteriaceae are probably more prevalent in Curacao than previously recognized.
