Microsoft claims its AI medical tool can outperform human doctors in diagnosing complex cases
Called the Microsoft AI Diagnostic Orchestrator (MAI-DxO), the system mimics a panel of five virtual doctors, each with its own specialty, working together to debate and diagnose.
In trials, it solved nearly 86 per cent of difficult medical cases published in The New England Journal of Medicine, which is known for complexity.
That is over four times more accurate than experienced human doctors under the same conditions, according to the tech's co-founder Dr Mustafa Suleyman.
'We're talking about models that are not just better, but dramatically better — faster, cheaper, and more accurate than human doctors,' Suleyman said.
Experts urge caution — it's early days.
The system made the diagnoses using patient data already provided, and clinical use is still a way off, with peer-review and safety testing ahead.
University of Sydney biomedical informatics professor Adam Dunn said it is not a real representation of what doctors do.
'These tools can be useful as an assistant, but they're never going to replace doctors,' Dunn told 7NEWS.
'The doctor has to quickly look at you and understand what kinds of questions to ask you to gather the right kinds of information.
'The second important thing to think about for ethics is related to who the AI is intended to support.
'In a lot of cases if the data are from one hospital in Boston, it's not a representative population.
'The decisions that an AI can make may be unfair. They may not be protecting our most marginalised and vulnerable populations.'
Artificial intelligence is currently being used across healthcare in many areas, with one standing out in terms of popularity.
Known as AI Scribes, the system listens to the conversation between a patient and a doctor or healthcare provider, and then quickly summarises the chat for medical records.
Australian Medical Association chair of public health Dr Michael Bonning said it allows the clinician to spend more time with the patient and less on paperwork.
'We know, and many practitioners will say this, that because of the time pressures on their day, they will often write a short series of notes and then rely on their memory of the consultation as well to provide further insight down the track,' Bonning told 7NEWS.
'In a six or eight-hour day, you might spend an hour and a half of that typing. And if in that circumstance you can let the AI do that, that's a huge time saving for a clinician.'
Doctors still review the transcription.
'Cannot replace humans'
Members of the public told 7NEWS they welcome the use of artificial intelligence as a tool to assist doctors, but would not trust the computer in place of a human doctor.
'I think it can be used as a support b, butot completely replacing humans,' one person said. 'I think we still have to have human reviewing in there.'
Another said a 'human doctor is still better, but I guess everything is artificial intelligence'.
'It's scary, but at the same time you don't know what the future holds with AI. It's both good and bad.'

Companies are busy preparing for an AI workforce
Microsoft, by chief executive Satya Nadella's own description, is 'thriving'. Its quarterly profits soared by almost 25 per cent and its market valuation hit $US4 trillion ($6.2 trillion) last week. In any normal situation, it would seem incongruent that the company is at the same time slashing its workforce by the thousands. Financial Times

Simple way Aussies are dropping weight without any exercise: ‘I've lost 11 kilos in eight weeks'
A weight loss program beloved by thousands of Aussie women up and down the country for helping them to shift stubborn kilos without exercise is currently 40 per cent off. equ — which was founded by Amal Wakim after her own transformative 30kg weight loss journey — has since empowered more than 60,000 women across Australia to reshape their bodies and habits. Right now, you can save 40 per cent off its personalised nutrition program with the code WINTER 40. The equ program works by providing daily individually-tailored calorie and macronutrient targets to women, along with access to an extensive library of more than 9,000 recipes. Those who have tried the program have not only had major success, but they have also been able to still enjoy the foods they love like burgers, pasta and pizza. Reviews online for equ are glowing, with one woman saying she has lost more than 11 kilograms in around two months. 'I've lost 11.5 kilos in just eight weeks thanks to equ,' Jess writes on the equ website. 'The meals are so yum I've never felt like I'm missing out — this is the longest I've ever stuck with something, and I'm so proud.' Another woman called Danielle says: ' I've lost 22kg since June 2024 thanks to equ — while still enjoying chocolate every night. 'As a mum of two, I needed something sustainable and stress-free, and e qu delivered. The support, the food, and the flexibility have made all the difference.' Jacinta adds: ' I've lost 13kg and completely transformed my life. ' equ gave me the tools to go from unhealthy and unhappy to fit, confident and balanced — and I've learned I really can have my cake and eat it too.' equ founder Amal Wakim famously lost more than 30 kilograms after her GP told her she was pre diabetic. To start with, she removed all carbohydrates from her diet and distanced herself from the long tables of food at family gatherings. She even denied herself cake — on birthdays including her own. For three years, Amal stuck to strict dieting and exercise. But she claims she was 'miserable'. So she slowly began reintroducing foods while also researching nutrition. 'I learnt how to nourish your body, a more sustainable approach to dieting,' she previously told 7NEWS. 'It's basic 80 per cent whole foods like your fruit, veg and protein and 20 per cent indulgence.'

How do doctors treat starvation?
As deaths from starvation in the Gaza Strip continue to rise, experts say there's no easy way out of the crisis due to the medical complexity of treating severe malnutrition. More than 160 people — at least 90 of them children — have died of malnutrition since the war began, according to Gaza's Health Ministry. The world's leading body on hunger, the Integrated Food Security Phase Classification (IPC), says that nearly all of Gaza is suffering a food security crisis or worse, and more than half of the population is in the 'emergency' or 'catastrophe' phase of starvation — which means recovering isn't as simple as giving starving people food. Know the news with the 7NEWS app: Download today Rather, giving food to people experiencing such an extreme degree of starvation could kill them, experts say. 'If you do what the body wants to do, which is to just drink and eat as much as possible the minute you see food, you can actually create these permanent imbalances that can cause things like heart failure or organ damage, because the body had to adapt to get to that starvation mode,' NBC News medical contributor Dr Kavita Patel, an internal medicine doctor, said. At the most severe stages of starvation, even giving a person water can push their body into failure, Patel said. What happens to the body when it's starving? Humans can generally go without any food or water for several days because the body finds a way to adapt in order to survive. First by feeding off of so-called glycogen stores — a starchy substance from carbohydrates that's stored in the liver and muscles. The body stores about 1700 to 2200 calories' worth of energy as glycogen. 'That's the first thing your body goes for that can get you through without eating or any water for about several days, in some cases, maybe a little longer,' Patel said. Once those glycogen stores are depleted, the body starts to break down fat for energy, but when that's gone, it turns to muscle. This is what causes the body to shrink and the starving person to assume a gaunt, hollow-cheeked look. Eventually the brain doesn't have the energy it needs to function, leading to irritability, mood swings and trouble concentrating. 'It's very hard to even just make sound judgments,' Patel said. 'You can see people have psychotic illusions. You can see people hearing things. All of that is basically the body's way of surviving.' Most starving people die from infections as their immune system shuts down. Eventually, the heart will be affected, causing a person's blood pressure and pulse to drop. If they don't die from infection, the heart will shut down, doctors said. The more vulnerable parts of the population are likely to suffer the most. 'Children — specifically infants — pregnant women, the elderly and people with certain kinds of chronic illness are the risk groups that we need to pay special attention to,' said Dr Irwin Redlener, a clinical professor of paediatrics at the Albert Einstein College of Medicine in New York City. How is starvation treated? Patel said a good analogy to giving food to a starving person is a downpour after a drought. The land desperately needs water, but because it's so dry it repels water instead of absorbing it, leading to flash flooding. 'Refeeding' after starvation needs to be managed clinically and by medical professionals. 'When a person has reached a state of starvation, the body undergoes extreme metabolic changes,' she said. 'Giving too much food — or the wrong kind — too quickly can trigger a dangerous shift in fluids and electrolytes known as refeeding syndrome, which can be fatal if not carefully managed.' 'A bag of flour — some of the only food aid that has gotten in recently — won't save anyone because it has none of the essential nutrients,' said Dr Nour Alamassi, a doctor and the medical team lead for Project HOPE, an international nongovernmental organisation focused on global health and humanitarian aid. 'Too many carbs can actually be life-threatening for anyone with Severe Acute Malnourishment (SAM), and even for the average person in Gaza who has not had a regular diet in many months, it is very difficult to digest,' Alamassi, who is caring for children and pregnant women in Gaza, wrote in an email. Ideally, doctors say, there would be enough medical staff to monitor the refeeding process for each person for a period stretching from weeks to even months. Children would be stabilised with fortified milks, which contain the nutrients that a malnourished child needs, and something called ready-to-use therapeutic foods (RUTF), which are energy-dense, easy to digest and carefully balanced in the nutrients children need to start to recover. Doctors would draw blood to monitor sodium and potassium levels, because if these electrolytes are too low or too high, it can be deadly. But the situation on the ground in Gaza is far from ideal. There are not enough doctors, not enough supplies and not the right supplies, experts say. 'The aid blockade has prevented us from accessing the medications and nutrition supplies that are necessary to treat these people,' Alamassi said. 'We recently ran out of High Energy Biscuits (HEB) in our clinics, which really limits our ability to help patients. 'We hope to get more in the coming days, but each day without these supplies can make a major difference for a patient's outcome.' What are the long-term effects of starvation? Even if refeeding is successful, people who survive starvation can experience physical and psychological effects for the rest of their lives, experts said. The damage, especially for young and very old victims, is permanent. In children, malnutrition can cause delays in both physical and cognitive development. Physically, they're more likely to have weakened immune systems, leading to a harder time recovering from infections. Malnourished children are also more likely to experience stunted growth, which can affect their height, muscle mass and bone density and even delay puberty, experts said. Cognitively, children can suffer from permanent brain damage due to iron and zinc deficiencies, affecting their ability to learn and problem solve. Alamassi said the hunger crisis in Gaza is affecting 'an entire generation of children who will suffer lifelong consequences'. The recovery of adults from very severe malnutrition is not only possible, but likely, Redlener said. 'If it's done right, most adults, unless they're really at a terminal stage of undernutrition, the refeeding will result in restoration of everything — a far different story than the ability for a young child with prolonged malnutrition, where it's often impossible to get a full recovery,' he said. Patel said even people with a history of malnutrition are monitored over years to make sure their bodies are functioning properly. 'As they age and develop, different parts of the body pull on memories of that nutrition depletion,' she said. 'So the question we all have to ask ourselves is, how long are we going to be able to do this without having adequate support on the ground?'
