Blanket ban urged for controversial medical device
A study published in the Medical Journal of Australia last week, based on private health insurance data, found 23 per cent of patients who receive a stimulator will need revision surgery – most within 18 months. In comparison, total knee replacement operations have a lifetime reoperation rate of about 2 per cent.

Private Healthcare Australia facilitated the provision of the data but did not fund the study or the researchers.
The University of Sydney's Dr Caitlin Jones, who led the study, said that on the basis of the evidence her team had collected she would support a ban on new stimulation implantations outside clinical trials.
Associate Professor Adrian Traeger, a University of Sydney academic who led a review of spinal cord stimulators for lower back pain, also supported a ban.
'Given the substantial risks, I'd want to see clear benefits over placebo from rigorous clinical trials before these surgeries were offered to patients,' he said. 'We expect this standard of evidence for drugs – why should it be different for surgical procedures?'
Personal injury lawyers Gerard Malouf & Partners have been investigating a potential class action since late last year against stimulator makers, and have been interviewing patients, this masthead can reveal.
Michael Ferraro, a researcher at medical research institute NeuRA who co-authored a review of stimulation for general chronic pain, said a ban would be useful if it pushed the industry towards conducting high-quality, placebo-controlled trials to prove the devices worked as claimed.
Marcus Barlow, who received a spinal cord stimulator in 2019 and found it dramatically worsened his pain, said the devices 'absolutely' should be banned.
'I am happy to lend my support to anything that could get these vile devices banned once and for all,' he said.
Ian Burgess, CEO of the Medical Technology Association of Australia, which represents device manufacturers, said there was robust clinical trial and real-world data proving stimulators' effectiveness and safety.
'We must not allow insurers to dictate clinical care, patient outcomes or to block access to therapies that can be life changing and restore dignity and function to people living with chronic pain.'
In response to questions about the ban proposal, the association connected this masthead with Kaleena de Voigt, a patient who received a stimulator to deal with chronic pain from an operation.
Two weeks after her operation, she was able to return to work, and she is now largely pain free.
'Within two days, my pain was down 85 per cent. Within the first three to four months, I was down 75 per cent of my opioids,' she said.

De Voight said she had not experienced any side effects or complications from the procedure, and that her doctors had managed to adjust the stimulation to remove persistent pain she felt in her hands, legs and feet from a separate condition.
'To deprive people of something like this that is so effective for so many, I think would be really quite sad,' she said.

Vaping cartoon aims to prevent generation of addiction
A cartoon story of a teen coming face-to-face with a vape will be rolled out across schools nationally, which researchers say can stop the next generation of addiction. Anti-vaping program OurFutures has been approved for the national curriculum until 2028, involving an interactive cartoon co-designed by students and teachers telling early teens about the effects of vaping and how to refuse one. Those who received the cartoon education were less likely to vape compared to those with a standard health education on the issue, according to a trial by the University of Sydney's Matilda Centre. OurFutures is aimed at students in years 7 and 8, with the trial finding them 65 per cent less likely to vape or start vaping in the following 12 months. "Education, prevention, demand reduction is a critical part of our vaping strategy, we've also been online supporting influencers to promote positive messages about vaping or healthy messages about vaping online," Health Minister Mark Butler told reporters in announcing government approval for the program on Tuesday. The Matilda Centre's Lauren Gardner said the average onset age for vaping is 14, and harmful patterns can be prevented by targeting the age group. The characters are also teens as students are more likely to accept "peer-to-peer" messaging than from authority figures such as teachers or police. "It allows them to immerse themselves in that story and think 'OK, if one of my peers can do it this way, this is how I can apply it in my own way'," Dr Gardner said. The rollout comes as the government continues cracking down on the regulated substance, with vapes only able to be legally purchased from pharmacies. Almost $500 billion worth of illicit vapes have been seized at the border since January 2024, but vape shops and tobacconists are leading a rise in black market sales according to a report by research project Generation Vape. Mr Butler said while that remains an issue, it is more expensive to buy a vape now than previously. Since tighter laws on the flavoured-air substances came into effect in July 2024, smoking rates have increased and vaping rates have only slightly decreased among adults, data from Roy Morgan has shown.

You don't need to walk 10,000 steps to benefit from its ‘health benefits'
Ten thousand steps per day has been widely recommended as the standard benchmark for physical activity — but a new study suggests that just 7000 could be enough to boost essential health markers. Researchers from the University of Sydney conducted a review of 57 studies spanning more than 10 countries, which tracked participants' steps and health outcomes. Led by Professor Melody Ding from the School of Public Health, the team looked at how different daily step counts impacted the risk of dying from heart disease and cancer, as well as the risk of developing cancer, type 2 diabetes, dementia and depression, according to a university press release. And it turns out, you may not need as many steps as was first thought. Researchers found that walking at least 7000 steps a day was linked to improvement in eight major health outcomes, including heart disease, dementia and depressive symptoms. 'Any increase in daily steps, even modest ones like 4000 steps, delivers health benefits compared to very low activity levels,' Ding told Fox News. 'When possible, targeting around 7000 steps per day can substantially reduce risks for many chronic diseases and adverse health outcomes. 'Even small increases in step counts, such as increasing from 2000 to 4000 steps a day, are associated with significant health gain.' Higher step counts beyond 7000 may add extra benefits, but the improvement rate slows, she noted. The results were published in The Lancet Public Health journal. In particular, the researchers found that walking 7000 steps a day reduced the risk of death by 47 per cent, almost exactly the same as 10000 steps. That same step benchmark was also linked to a 38 per cent reduced risk of dementia and a 22 per cent reduced risk of type 2 diabetes, both only slightly lower than the benefit of 10,000 steps, the release stated. 'Significant health improvements' were reported when people increased from 2000 steps per day to anywhere between 5000 and 7000. 'Aiming for 7000 steps is a realistic goal based on our findings, which assessed health outcomes in a range of areas that hadn't been looked at before,' said Professor Ding in the release. 'However, for those who cannot yet achieve 7000 steps a day, even small increases in step counts, such as increasing from 2000 to 4000 steps a day, are associated with significant health gain.' For those who are already very active and consistently hitting 10,000+ steps, Ding said, 'keep it up — there's no need to cut back'. The researchers also noted that stepping doesn't need to happen all at once or require intentional exercise. 'Everyday movements count — like getting off the bus a stop earlier or choosing stairs over elevators,' Ding advised. 'Small, incidental bouts throughout the day add up and contribute to health. Embrace opportunities to move more in practical, enjoyable ways.' There were some limitations in the study, the researchers noted. 'For some outcomes, we have a small number of studies,' Ding told Fox News. There are also some study-level biases, she said. 'For example, people who are already unwell will take fewer steps because of their health conditions,' Ding said. 'And while there is an indication that the dose-response may be different for older adults, we didn't have enough data for all outcomes to explore it.' It's also important to note that while walking offers great health benefits, it is not a complete 'package' in itself, she noted. 'Everyday movements count — like getting off the bus a stop earlier or choosing stairs over elevators,' Ding said. 'Try to also incorporate strength training and mobility exercise into a weekly routine for more complete health benefits.' In next steps, the researchers plan to use these findings to shape future physical activity guidelines.

Plan to boost gender equity among engineering academics
Female academics are being encouraged into engineering roles as part of a bid to boost gender equity and representation in the sector. The University of Sydney is running a campaign open to international and Australian candidates offering academic roles reserved for women in engineering. The roles are in the schools of aerospace, mechanical and mechatronic engineering, civil engineering, computer science, and electrical and computer engineering. About 12 to 17 per cent of continuing academic staff within these schools are women. But a 2024 Diversity Council Australia report found just 11 per cent of female engineering students qualified and went on to work in an engineering role, while the percentage of those in senior roles was even lower. Shuying Wu, a senior lecturer in aerospace, mechanical and mechatronic engineering at the University of Sydney, said she had been the only women in the room for many parts of her career. "There is a lack of female mentors so there can be limited guidance and inspiration," Dr Wu told AAP. "But when we design engineering projects, if we have more diversity we can solve problems from different angles as diverse teams create more solutions and think about things from different perspectives." Women had historically been under-represented in Australia's engineering sector, something culture and community associate dean Renae Ryan wants to change at the University of Sydney. Other universities had run similar campaigns which had successfully improved diversity among academics, she said. "Increasing diversity is not just about representation, it is also about institutions actively creating opportunities for talent to flourish, develop and grow," Professor Ryan said. "Having these kinds of identified rounds sends a strong signal that we are really serious about attracting talented women into our faculty and it also increases student interest because it highlights the pipeline for women engineers." As diversity, equity and inclusion programs are wound back in the United States, Prof Ryan expected American researchers and academics to be attracted to the roles. "There's a lot going on in research and funding in general in the US and there have been significant changes and a lot of people in the higher education sector are under pressure," she said. "It's something we are conscious of and we would always reach out to the US anyway, but there may be people looking for a change in Australia."
