The public associate visibly dirty wards with increasing rates of MRSA, but there is little evidence for the effectiveness of basic cleaning on reducing the risk of acquiring MRSA in health-care institutions. Furthermore, hospital hygiene is usually assessed visually, but this does not necessarily correlate with microbiological risk and fails to recognise that microorganisms, including human pathogens such as MRSA, are invisible to the naked eye*. However, the current standards for assessing hospital hygiene use visible cleanliness as a performance criterion.
Dr Stephanie Dancer (South General Hospital, Glasgow, UK) presents a robust case for targeted hospital cleaning as a strategy for controlling MRSA by reviewing the evidence for the potential impact of cleaning on each stage of the staphylococcal transmission cycle between patients, staff, and their environment. The author notes that cleaning is already accepted as an important factor in the control of other hardy environmental pathogens, such as Clostridium difficile, vancomycin-resistant enterococci, norovirus, and Acinetobacter spp, but argues that the role of near-patient hand-touch sites—such as door handles, bed rails, infusion pumps, and switches— in the transmission of MRSA and other pathogens, has not been given the priority it deserves.
According Dr Dancer, in the UK, ward cleaners work to a set specification that gives emphasis to the cleaning of floors and toilets, and yet the evidence for MRSA contamination of a huge variety of hospital items, and particularly hand-touch sites is overwhelming. Indeed, the author notes that these hand-touch sites, which might harbour and transmit microbial pathogens, are poorly cleaned.
The author concludes: “There can be no doubt that prioritising hand hygiene is the single most beneficial intervention in the control of MRSA…[but] even if everyone does wash their hands properly, the effects of exemplary hand hygiene are eroded if the environment is heavily contaminated by MRSA”. She goes on: “The increasing prevalence of MRSA and other multi-drug-resistant bacteria in UK hospitals support prioritisation of cleaning and other control measures before definitive validation”.

The Fraunhofer IWS Dresden and Technische Universität Dresden inaugurated their jointly operated Center for Additive Manufacturing Dresden (AMCD) with a festive ceremony on February 7, 2017. Scientists from various disciplines perform research on materials, additive manufacturing processes and innovative technologies, which build up components in a layer by layer process. This technology opens up new horizons for component design and combinations of functions. For example during fabrication, electrical conductors and sensors are already able to be additively manufactured into components. They provide information about stress conditions of a product during operation.
The 3D-printing technology, or additive manufacturing as it is often called, has long made the step out of scientific research laboratories into industrial...

Nanometer-scale magnetic perforated grids could create new possibilities for computing. Together with international colleagues, scientists from the Helmholtz Zentrum Dresden-Rossendorf (HZDR) have shown how a cobalt grid can be reliably programmed at room temperature. In addition they discovered that for every hole ("antidot") three magnetic states can be configured. The results have been published in the journal "Scientific Reports".
Physicist Dr. Rantej Bali from the HZDR, together with scientists from Singapore and Australia, designed a special grid structure in a thin layer of cobalt in...
