WA health breakthrough could use AI for early heart disease and cancer detection
A WA health breakthrough could make it easier to predict cancer or cardiovascular disease from a simple scan that costs as much as a cup of coffee and exposes patients to the same amount of radiation as flying from Perth to London. Edith Cowan University researchers have developed an artificial intelligence system that uses bone density scans — commonly known as DEXA scans — and ultrasounds to help medical experts pick up early signs of serious diseases. If successfully commercialised, the ECU-developed algorithm could pave the way for early detection and treatment of heart disease, cancer and diabetes-related blindness. ECU researcher Afsah Saleem said many chronic illnesses such as cardiovascular disease, which is responsible for one in four deaths, and diabetic retinopathy, a leading cause of blindness, were difficult to detect in the early stages 'because they lack obvious symptoms'. 'Current diagnostic methods frequently rely on manual assessments of medical scans, which is a time-consuming, expensive, and subjective process,' she said. 'Being a machine learning scientist and working in medical imaging, our aim is to prevent or delay permanent health losses from chronic diseases. 'Using this algorithm, we achieved 85 per cent accuracy and 79 per cent sensitivity in identifying abdominal aortic calcification, an early indicator of cardiovascular disease. We also obtained 87 per cent accuracy and 84 per cent sensitivity in diagnosing diabetic retinopathy, and 91 per cent accuracy in identifying different stages of breast cancer.' ECU senior lecturer Zulgarnain Gilani said the algorithm made it possible for disease signs to be picked up in a simple DEXA scan 'which costs you roughly a cup of coffee and the radiation is as small as you would be exposed to flying London to Perth'. 'The innovative aspect of the developed algorithm lies in its ability to capture and learn the distinctive characteristics of both healthy and unhealthy individuals,' he said. 'Subsequently, the algorithm effectively differentiates these traits to identify individuals afflicted with disease with remarkable precision.' Long-term, he said, the idea would be that a GP could simply send a patient for DEXA scan and a patient would receive a score for, for example, aortic calcification — an early indication of the risk of heart disease. Currently, the 'gold standard' for getting an aortic calcification score is to send patients for a CT scan, which is both significantly more expensive than a DEXA scan and exposes patients to higher levels of radiation. Dr Gilani and Dr Saleem are leading the AI aspect of the research, in collaboration with other researchers both at ECU and overseas in Canada, the US, the UK and Korea. It is backed by the Heart Foundation, Raine Medical Research Foundation and the WA Health Department.

Expert shares 9 ways to shrink belly fat naturally
Tucked deep inside your body, there's a type of fat that doesn't just sit there — it stirs up trouble. It surrounds your organs, messes with your metabolism, and quietly raises your risk for things like heart disease, diabetes, and more. It's called visceral fat, and the kicker is, you don't have to look overweight to have too much of it. In fact, even slim folks can carry dangerous levels of visceral fat — a condition sometimes referred to as 'skinny fat.' Unlike the soft layer just under your skin (subcutaneous fat), this kind hides out around your liver, kidneys, intestines, and heart, fueling inflammation and silently working against your health. How to tell if you've got too much visceral fat If visceral fat is about 10% of your body's total fat mass, that's normal and healthy, according to the Cleveland Clinic . According to the US Centers for Disease Control and Prevention . Generally, if your waist measures more than 35 inches for women or 40 inches for men, it may be time to take notice. But don't cheat the tape, breathe out naturally and wrap it just above your hip bones, right around the belly button. Another hint is your muscle-to-fat ratio. If you've lost muscle and gained fat, especially as you age, that imbalance can mean more visceral fat inside, even if the scale doesn't budge much. Tools like DEXA scans or smart body composition scales can offer more insight, but the everyday clues, low energy, weight gain around your midsection, or poor sleep, are often just as telling. Dr. Chris Chappel, on his social media page, recently shared nine habits that can naturally shrink visceral fat. Avoid late-night eating Eating close to bedtime isn't just about calories, it affects hormones like insulin, cortisol, and glucose, which all play a role in fat storage. Try shifting your biggest meals to earlier in the day and giving your body a few hours of fasting before bed. Embrace the cold Cold exposure, like a quick 1–2 minute cold shower or using an ice pack a few times a week, can activate brown fat, which burns energy to produce heat. It's not a miracle fix, but it can help reduce waistline over time when done consistently. Move more It's not just about your workouts. Daily movement that isn't 'exercise', like walking while on the phone, cleaning the house, or taking the stairs, actually burns a surprising amount of fat. It's called NEAT (non-exercise activity thermogenesis), and it adds up fast. Apple cider vinegar before meals Taking a tablespoon of diluted apple cider vinegar about 10 minutes before meals has been shown to reduce post-meal blood sugar spikes. Stable blood sugar means less fat storage, particularly around the belly. Prioritize sleep Sleep isn't just rest, it's a reset button for your hormones. Getting less than 6 hours a night over time is linked to significant increases in visceral fat. Aim for 7 to 9 hours, cut screen time before bed, and sleep in a cool, dark room. Add more soluble fiber Soluble fiber helps regulate blood sugar, supports gut health, and improves insulin sensitivity, all of which play a part in reducing belly fat. Some good sources: avocados, oats, flaxseeds, and Brussels sprouts. Rethink your cooking oils Highly processed oils like canola, soybean, and corn oil can fuel inflammation, which plays a big role in fat gain. Instead, reach for olive oil, avocado oil, or even grass-fed butter in moderation. Lift weights Resistance training just two or three times a week can lower visceral fat, even if your weight doesn't drop. Building muscle improves insulin sensitivity, which helps your body manage fat storage more efficiently. Start your day with protein Skipping protein in the morning is a missed opportunity. A breakfast with 30–40 grams of protein helps reduce hunger later in the day and keeps blood sugar levels steady. Try eggs, Greek yogurt, a protein shake, or lean meats like turkey sausage.

The Silent Risk In Menopause: Why Bone Health Needs More Attention
Last Updated: As women approach menopause, adding a bone scan to your health checkup can help you understand your bone density and the risk of osteoporosis. For many women, menopause brings a cascade of physical and emotional changes, but one of the most overlooked concerns is bone health. Osteoporosis, a condition where bones lose density and become weak, often creeps in quietly during this time. It significantly increases the risk of fractures, especially in older women. 'The risk of osteoporosis rises sharply during peri- and postmenopausal years due to a decline in oestrogen and testosterone levels," says Dr. Jyotsna R Mirlay, Consultant – OBG, Specialist in Infertility & Menopause, Manipal Hospital Malleshwaram. 'These hormones play a vital role in maintaining bone strength. Their absence leaves bones more vulnerable to damage," adds Dr Mirlay. While awareness around screenings for breast, cervical, and uterine cancers has grown, conversations about bone and muscle health are still limited. 'Women and even healthcare providers often overlook bone health. But a simple DEXA scan can be a game-changer," Dr. Mirlay explains. 'It checks bone density in key areas like the spine, wrist, and hip, and also gives insight into a woman's muscle mass." Fractures due to osteoporosis aren't just painful; they're often life-altering. 'There can be no better way to ensure a healthy menopause than to treat bone and muscle tissue loss early," says Dr. Mirlay. 'It acts as insurance against fractures, which are a major cause of disability and even death in older women." Maintaining bone strength ensures mobility, independence, and quality of life as women age. Making Smart Lifestyle Choices The good news? Much of this is preventable. Dr. Mirlay recommends a two-pronged approach of nutrition and movement. 'A diet rich in protein, calcium, and vitamin D is crucial. And exercise: especially walking, weight training, yoga, and swimming, makes a big difference," she says. 'Osteoporosis and sarcopenia result from poor lifestyle choices, worsened by menopause. Awareness in the 30s can go a long way in building consistency and preventing long-term damage." she concludes. Supplements and medical treatments can help in more advanced cases, but prevention starts much earlier. view comments Disclaimer: Comments reflect users' views, not News18's.

Radiology In Women's Health: Breaking The Fear Around Scans
Radiology isn't about fear; it's about clarity. t's about seeing what needs to be seen early, accurately, and safely to give you the best chance at a healthy life A common apprehension often arises when a doctor suggests a scan. 'Is it necessary?" 'What about radiation?" 'Will it be painful?" These questions reflect a deeply ingrained fear, particularly among women, surrounding medical imaging. 'As healthcare professionals, addressing this fear is crucial, as it can become a barrier to timely diagnosis—and ultimately, to saving lives," says Dr Sunita Dube, Radiologist and Chairperson of MedScapeIndia. Dr Dube shares her insights on this deeply ingrained fear and how important it is to overcome it for your own health. Radiology is a powerful ally in a woman's health journey. From early breast cancer detection to monitoring a healthy pregnancy, from assessing bone density to identifying uterine fibroids, these scans offer an unparalleled glimpse into the body. Yet, anxiety frequently overshadows their immense benefits. Why does this fear persist? Often, it stems from a lack of understanding. The word 'radiation" instantly conjures danger, despite our daily exposure to natural radiation. Modern diagnostic techniques use minimal, safely calibrated doses. The risk, if any, is negligible compared to the life-saving information provided. There's also the fear of the unknown: the enclosed space of an MRI, the pressure of a mammogram, or the dread of what a scan might reveal. While it is natural to feel apprehensive, such fear must not lead to avoidance. Consider women's health. Early breast cancer detection through mammography dramatically improves survival rates. Cervical health can be thoroughly assessed with imaging. Osteoporosis, a silent, bone-weakening condition can be detected early with DEXA scans, helping prevent debilitating fractures. During pregnancy, ultrasounds provide both joy and crucial insights into fetal development, ensuring the safety of both mother and child. These procedures are vital windows into prevention, accurate diagnosis, and effective treatment. Healthcare providers are working to demystify these processes. A mammogram is quick. An ultrasound is painless, using sound waves. An MRI provides detailed images of soft tissue without using X-rays. Skilled technicians and radiologists are dedicated to ensuring your comfort and delivering accurate image interpretations, turning complex data into actionable insights for your doctor. But the true power lies with you. It's the power of knowledge and proactive health management. Ask questions. Understand why a scan is recommended. Share your concerns. Your body is yours—understanding its needs is empowering. Don't let unfounded fears dictate your health choices. Embrace these technological marvels as tools designed for your well-being. Radiology isn't about fear; it's about clarity. It's about seeing what needs to be seen early, accurately, and safely to give you the best chance at a healthy life. Let us break free from apprehension and step forward, informed and empowered, embracing the full spectrum of healthcare available to us. Your health is your wealth, and embracing scans is a vital investment in it. view comments Disclaimer: Comments reflect users' views, not News18's.

I went to a medical clinic in Portugal — thousands of miles from my NYC home. I saved $500 and found an answer for my back pain.
I visited a Lisbon longevity clinic to address persistent injuries and lower back pain. The clinic offers body scans and osteopathy, revealing insights into muscle imbalances. These tests are costly in the US, but cost a fraction of the price in Portugal. I'm OK with aging — it's a privilege to get older! I don't feel the need to invest in expensive supplements to subtract 15 years from my biological age or get a vampire facial to look a few years younger. At the same time, I'm a runner, trying to learn more about my body. That's why I ended up at a longevity clinic in Lisbon, about 3,400 miles from my home in New York City. I'd spent most of 2024 managing a few injuries. First, a grade 2 MCL tear in my left knee, after dancing in shoes that couldn't quite handle my moves. After I was cleared to run, I went a little too hard, leading to tendonitis in the Achilles and peroneal tendons of my right foot. I did everything you're supposed to do: physical therapy, low-impact cardio, and strength training. Still, I felt frustrated and stagnant. Without my regular workout routine, I felt my muscles stiffen everywhere in my body, reviving a pain I get in my lower back when I'm not active. I wanted to get to the bottom of these incessant, random aches. While staying in Portugal earlier this year, a friend, who's a physician, recommended I check out MetaClinic, a wellness center in the heart of Lisbon. It's marketed as a one-stop shop for wellness, offering everything from hormonal health assessments to body composition and metabolic rate testing. While my sports doctors and physical therapists in New York City are phenomenal, it often felt like we were treating each issue separately rather than exploring how one might be leading to another. I was drawn to MetaClinic's mission of connecting the dots within the body. As a freelance journalist with basic marketplace health insurance, I gained more from the experience than I could have imagined for a fraction of the cost in the US. And one appointment, which I decided to tack on at the last minute, may have helped identify the cause of my years-long back pain. I got 2 body scans to measure my muscles, body fat, and metabolism I began with two tests commonly offered at private longevity clinics, a new kind wellness center that is booming worldwide. First, I did the DEXA scan, a low-dose X-ray that measures your bone density, muscle mass distribution, and body fat percentage. Second, the indirect calorimetry test, a breathing assessment that measures your resting metabolic rate (or, the amount of calories you burn throughout your waking day). Together, these cost me €190 (or $224). While these tests are available in the US, I'd never considered them since they would cost up to $1,200. According to the clinic's website, these scans would provide a vivid picture of how my body works. As a health journalist, I was a little skeptical about how much I could learn from five- to 15-minute tests. "These are essential factors for health," Dr. Andrea Maier, one of the world's leading longevity researchers who offers these tests at her clinic in Singapore, told me. However, she echoed my concern. These scans only give a small glimpse into the bigger picture of what's going on with my body, she said. You need to take the findings with a grain of salt, and combine them with other tests — measuring your VO2 max and studying your diet, for example. I wanted to try it because, according to research, muscle mass distribution can tell you a lot about a body — present and future — from heart health to disease risk. I was curious to see if my year of reduced physical activity had affected my health. The DEXA scan was a pleasant experience. After lying still on a table for about 10 minutes while my entire body was scanned inch by inch, I got my results. Thankfully, I learned I had minimal visceral adipose tissue (a type of harmful fat), which is linked to lower inflammation and a lower risk of age-related diseases. I felt relieved! However, my total body fat content was on the high end of the normal range, at 35.8%. My technician at MetaClinic said this range was completely fine, but Maier advised I should aim to reduce it and increase my muscle mass. That didn't surprise me, given I hadn't been strength training at all, as I was afraid of aggravating my injuries while abroad. The calorimetry test was not so simple. My technician said, "It's time to wrap you like a present," before she put a dome-like helmet over my head and wrapped my entire body in plastic. The goal of this 15-minute test is to measure how much energy (calories) your body burns at rest, but not when it's asleep. It measures the oxygen you breathe in and the carbon dioxide you exhale, to see how efficiently your body is using oxygen to generate energy. My results indicated that I burn, on average, about 1,400 kcal/day by just existing. (Research suggests this is in line with the average.) For anyone looking to better understand how their body is changing over time, these tests can be a good starting point, but it doesn't tell you much in a vacuum. The osteopath identified a source of back pain I'd never considered At the last minute, I decided to meet with the clinic's osteopath, a licensed doctor whose medical practice looks at the whole person in a holistic sense. I hadn't tried this area of medicine before. In New York City, one appointment with a DO (doctor of osteopathic medicine) could cost anywhere from $135-$400 out of pocket for one appointment. Here, it cost me €60 ($70). Looking at me, she said she could tell I'd been doing calf raises on my right foot because that calf was notably bigger than my left. To achieve muscle balance between my left and right legs, she said I should be doing my physical therapy exercises on my healthy leg, too, not just on the injured side. Then she assessed my lower back pain. While I was lying face down on the table, she started at my feet and worked her way up. She found that my hamstrings were unusually tight. Normally, when I have back pain, my physical therapists target my glutes — right beneath the joint where I feel tightness. I hadn't considered that my pain could be stemming from my hamstring, and that it could be the result of my left foot taking on more of the load when walking to compensate for the discomfort in my right heel. When I got back to New York City, I started working out biweekly with a friend who's a personal trainer to help address these muscle imbalances. Four months in, I can't believe how much better both my back and right heel are feeling. Why Americans fly abroad for longevity tests In the US, these tests don't feel affordable. I'm glad I seized this opportunity while working in Lisbon for two months through the winter. In total, I paid just $224 for all three of these assessments without health insurance. In the US this collection of tests would have set me back between $400 and $1,200, depending on insurance coverage. While all of the information I got from my day at MetaClinic may just be a "starting point," I found it helped me get a fresh perspective on how to manage discomfort on both sides of my body. I have the New York Marathon coming up in November, so I'm actively working on getting my muscles prepared for the demands of training.
