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 more electronics steer, accelerate and brake cars, the more important it is to protect them against cyber-attacks. That is why 15 partners from industry and academia will work together over the next three years on new approaches to IT security in self-driving cars. The joint project goes by the name Security For Connected, Autonomous Cars (SecForCARs) and has funding of €7.2 million from the German Federal Ministry of Education and Research. Infineon is leading the project.

A research team led by physicists at the Technical University of Munich (TUM) has developed molecular nanoswitches that can be toggled between two structurally different states using an applied voltage. They can serve as the basis for a pioneering class of devices that could replace silicon-based components with organic molecules.
The development of new electronic technologies drives the incessant reduction of functional component sizes. In the context of an international collaborative...

At this year's LASYS, the LZH will exhibit light-based processes such as cutting, welding, ablation and structuring as well as additive manufacturing for...
There are videos on the internet that can make one marvel at technology. For example, a smartphone is casually bent around the arm or a thin-film display is rolled in all directions and with almost every diameter. From the user's point of view, this looks fantastic. From a professional point of view, however, the question arises: Is that already possible?
At Display Week 2018, scientists from the Fraunhofer Institute for Applied Polymer Research IAP will be demonstrating today’s technological possibilities and...
