Following a review by the Therapeutic Goods Administration (TGA), a range of popular painkillers will carry a stronger warning, alerting users to the potential for increased risk of heart attack, stroke and in the case of diclofenac, liver toxicity. [ + ]

Emerging evidence suggests physical activity is a good means of preventing a stroke. In the event that someone who regularly exercises does have a stroke, they are likely to have a less severe stroke and better outcomes in the early and later stages of rehabilitation. [ + ]

Antibiotics must be used at the right time, in the right dose, for the right length of time, and for the right reason. These are among the important messages in Antibiotic Awareness Week 2015. [ + ]

With terror attacks increasing across the globe, the spotlight is on paramedics who are often the first respondents to major emergencies. Research conducted by Garry Stevens and his team from the Disaster Response & Resilience Research Group (DRR), University of Western Sydney, reveals that a paramedic’s confidence and willingness to respond to chemical, biological, radiological, nuclear, and explosives-related (CBRNE) incidents differs from that relating to their ‘routine’ emergency work.

Malaria is responsible for almost half a million deaths a year, mainly in developing countries. The parasite undergoes a complex life cycle that requires two hosts – a mosquito and a mammal. New research from The University of Nottingham could reveal how the malaria parasite thrives within its insect and human hosts, leading to potential new treatments. [ + ]

Software 'agents' modelled on real-life individuals will be used by University of Sydney researchers to develop high-precision computer models that can predict where or when an epidemic may strike. [ + ]

A team led by University of California, San Francisco (UCSF) has developed a technique to build tiny models of human tissues, called organoids, more precisely than ever before, using a process that turns human cells into a biological equivalent of LEGO bricks. These mini-tissues in a dish can be used to study how particular structural features of tissue affect normal growth or go awry in cancer. They could be used for therapeutic drug screening and to help teach researchers how to grow whole human organs. [ + ]

A four-month inquiry into the role of registered nurses within residential aged care in NSW, found shifts led by a registered nurse often reduced unnecessary hospitalisations and increased the quality of clinical care within residential aged sites. [ + ]

Non-melanoma skin cancers (NMSCs) are the most common cancers in Australia and account for seven out of every eight new cancers diagnosed. Unlike melanomas that are less common and more aggressive, NMSCs are relatively easy to treat and rarely spread to other parts of the body. People who do get non-melanoma skin cancers, however, particularly before the age of 25, are at a much greater risk of developing 30 other cancers, including breast, colon and lung cancers. This is according to research  by Dr Rodney Sinclair and colleagues, published in Cancer Epidemiology, Biomarkers & Prevention. [ + ]

A $2.1 million grant from the National Health and Medical Research Council announced today will see UNSW Professor Colleen Loo lead Australia’s largest clinical trial of ketamine as a new treatment for major depression. [ + ]

The first works have begun on stage one of the largest hospital redevelopment in NSW, at Sydney’s Westmead Hospital, that will see the children’s and adult’s emergency departments combined. [ + ]
