Time for a culture change? suboptimal compliance with blood culture standards at a district hospital in Cape Town
(Health and Medical Publishing Group, 2015)Background. The benchmark for contaminated blood cultures (BCs) is 3%. The South African (SA) guideline aims to optimise BC yield and reduce contamination. Data on BC collection practices in SA since the publication of the ... -
Role of infection control in combating antibiotic resistance
(Health & Medical Publishing Group, 2015)Infection control has been identified as one of the key interventions in controlling the threat of antibiotic resistance. Reducing the transmission of multidrug-resistant organisms (MDROs) reduces the need for broad-spectrum ... -
Obesity is associated with increased seminal insulin and leptin alongside reduced fertility parameters in a controlled male cohort
(BioMed Central, 2014)Background: Obesity appears to be associated with male reproductive dysfunction and infertility, although this has been inconsistent and inconclusive. Insulin and leptin are known mediators and modulators of the ... -
