Background: Chronic wounds are a silent epidemic in Australia. They are an under-recognised public health issue, and their significant health and economic impact is underestimated. Evidence-based practice in wound care has significant health and economic benefits, yet there are still considerable evidence–practice gaps. Methods: Stakeholders attended a national forum to refine and prioritise solutions to the chronic wounds problem in Australia. A survey was administered to identify key priorities and recommendations. Results: Stakeholders agreed on 17 recommendations and strategies to improve the outcomes of Australians with chronic wounds. The identified priorities for immediate action were to raise awareness of the significance of chronic wounds, and to make chronic wounds a strategic priority for governments. The Chronic Wounds Solutions Collaborating Group was established to encourage, support and monitor action on the implementation of these recommendations. Conclusions: Large health and economic gains can be achieved with modest investments in evidence-based strategies for the prevention and control of chronic wounds in Australia. We call for a critical and sustained national effort to prevent and treat chronic wounds in Australia. Urgent action is needed at all levels if Australia is to reduce the significant preventable burden of chronic wounds and improve patient outcomes.

We report on new simultaneous in-situ observations at Mars from Rosetta and Mars Express (MEX) on how the Martian plasma environment is affected by high pressure solar wind. A significant sharp increase in solar wind density, magnetic field strength and turbulence followed by a gradual increase in solar wind velocity is observed during ~24 h in the combined data set from both spacecraft after Rosetta's closest approach to Mars on 25 February 2007. The bow shock and magnetic pileup boundary are coincidently observed by MEX to become asymmetric in their shapes. The fortunate orbit of MEX at this time allows a study of the inbound boundary crossings on one side of the planet and the outbound crossings on almost the opposite side, both very close to the terminator plane. The solar wind and interplanetary magnetic field (IMF) downstream of Mars are monitored through simultaneous measurements provided by Rosetta. Possible explanations for the asymmetries are discussed, such as crustal magnetic fields and IMF direction. In the same interval, during the high solar wind pressure pulse, MEX observations show an increased amount of escaping planetary ions from the polar region of Mars. We link the high pressure solar wind with the observed simultaneous ion outflow and discuss how the pressure pulse could also be associated with the observed boundary shape asymmetry. ; NJTE was supported by the European Union 6th Framework, contract MEST-CT-2004-7512.
