From eye exams to blood tests and surgery: how doctors use light to diagnose disease

<div class="theconversation-article-body"><em><a href="https://theconversation.com/profiles/matthew-griffith-1539353">Matthew Griffith</a>, <a href="https://theconversation.com/institutions/university-of-south-australia-1180">University of South Australia</a></em></p> <p>You’re not feeling well. You’ve had a pounding headache all week, dizzy spells and have vomited up your past few meals.</p> <p>You visit your GP to get some answers and sit while they shine a light in your eyes, order a blood test and request some medical imaging.</p> <p>Everything your GP just did relies on light. These are just some of the optical technologies that have had an enormous impact in how we diagnose disease.</p> <h2>1. On-the-spot tests</h2> <p>Point-of-care diagnostics allow doctors to test patients on the spot and get answers in minutes, rather than sending samples to a lab for analysis.</p> <p>The “flashlight” your GP uses to view the inside of your eye (known as an <a href="https://medlineplus.gov/ency/article/003881.htm">ophthalmoscope</a>) is a great example. This allows doctors to detect abnormal blood flow in the eye, deformations of the cornea (the outermost clear layer of the eye), or swollen optical discs (a round section at the back of the eye where the nerve link to the brain begins). Swollen discs are a sign of elevated pressure inside your head (or in the worst case, a brain tumour) that could be <a href="https://www.hopkinsmedicine.org/health/conditions-and-diseases/headache/increased-intracranial-pressure-icp-headache">causing your headaches</a>.</p> <p>The invention of <a href="https://openmedscience.com/lighting-the-way-in-healthcare-the-transformative-role-of-lasers-in-medicine/">lasers and LEDs</a> has enabled many other miniaturised technologies to be provided at the bedside or clinic rather than in the lab.</p> <p><a href="https://theconversation.com/whats-a-pulse-oximeter-should-i-buy-one-to-monitor-covid-at-home-174457">Pulse oximetry</a> is a famous example, where a clip attached to your finger reports how well your blood is oxygenated. It does this by <a href="https://www.howequipmentworks.com/pulse_oximeter/">measuring</a> the different responses of oxygenated and de-oxygenated blood to different colours of light.</p> <p>Pulse oximetry is used at hospitals (and <a href="https://theconversation.com/whats-a-pulse-oximeter-should-i-buy-one-to-monitor-covid-at-home-174457">sometimes at home</a>) to monitor your respiratory and heart health. In hospitals, it is also a valuable tool for detecting <a href="https://www.thelancet.com/journals/lancet/article/PIIS0140-6736(12)60107-X/fulltext">heart defects in babies</a>.</p> <h2>2. Looking at molecules</h2> <p>Now, back to that blood test. Analysing a small amount of your blood can diagnose <a href="https://theconversation.com/blood-tests-and-diagnosing-illness-what-can-blood-tell-us-about-whats-happening-in-our-body-80327">many different diseases</a>.</p> <p>A machine called an automated “full blood count analyser” tests for general markers of your health. This machine directs focused beams of light through blood samples held in small glass tubes. It counts the number of blood cells, determines their specific type, and reports the level of haemoglobin (the protein in red blood cells that distributes oxygen around your body). In minutes, this machine can provide a <a href="https://www.nuffieldhealth.com/article/inside-the-pathology-lab-what-happens-to-my-blood">snapshot</a> of your overall health.</p> <p>For more specific disease markers, blood serum is separated from the heavier cells by spinning in a rotating instrument called a centrifuge. The serum is then exposed to special chemical stains and enzyme assays that change colour depending on whether specific molecules, which may be the sign of a disease, are present.</p> <p>These colour changes can’t be detected with the naked eye. However, a light beam from an instrument called a <a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC5476943/#R88">spectrometer</a> can detect tiny amounts of these substances in the blood and determine if the biomarkers for diseases are present, and at what levels.</p> <h2>3. Medical imaging</h2> <p>Let’s re-visit those medical images your GP ordered. The development of fibre-optic technology, made famous for transforming high-speed digital communications (such as the NBN), allows light to get inside the body. The result? High-resolution optical imaging.</p> <p>A common example is an <a href="https://www.medicalnewstoday.com/articles/153737#risks-and-side-effects">endoscope</a>, where fibres with a tiny camera on the end are inserted into the body’s natural openings (such as your mouth or anus) to examine your gut or respiratory tracts.</p> <p>Surgeons can insert the same technology through tiny cuts to view the inside of the body on a video screen during <a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC9553337/">laparoscopic surgery</a> (also known as keyhole surgery) to diagnose and treat disease.</p> <h2>How about the future?</h2> <p>Progress in nanotechnology and a better understanding of the interactions of light with our tissues are leading to new light-based tools to help diagnose disease. These include:</p> <ul> <li> <p><a href="https://onlinelibrary.wiley.com/doi/full/10.1002/advs.201903441">nanomaterials</a> (materials on an extremely small scale, many thousands of times smaller than the width of a human hair). These are being used in next-generation sensors and new diagnostic tests</p> </li> <li> <p><a href="https://www.nature.com/articles/s41587-019-0045-y">wearable optical biosensors</a> the size of your fingernail can be included in devices such as watches, contact lenses or finger wraps. These devices allow non-invasive measurements of sweat, tears and saliva, in real time</p> </li> <li> <p>AI tools to analyse how blood serum scatters infrared light. This has allowed researchers to build a <a href="https://www.advancedsciencenews.com/powerful-diagnostic-approach-uses-light-to-detect-virtually-all-forms-of-cancer/">comprehensive database</a> of scatter patterns to detect <a href="https://onlinelibrary.wiley.com/doi/full/10.1002/aisy.202300006">any cancer</a></p> </li> <li> <p>a type of non-invasive imaging called <a href="https://www.ncbi.nlm.nih.gov/books/NBK554044/">optical coherence tomography</a> for more detailed imaging of the eye, heart and skin</p> </li> <li> <p>fibre optic technology to deliver a tiny microscope into the body on the <a href="https://www.uwa.edu.au/projects/microscope-in-a-needle">tip of a needle</a>.</p> </li> </ul> <p>So the next time you’re at the GP and they perform (or order) some tests, chances are that at least one of those tests depend on light to help diagnose disease.<img style="border: none !important; box-shadow: none !important; margin: 0 !important; max-height: 1px !important; max-width: 1px !important; min-height: 1px !important; min-width: 1px !important; opacity: 0 !important; outline: none !important; padding: 0 !important;" src="https://counter.theconversation.com/content/231379/count.gif?distributor=republish-lightbox-basic" alt="The Conversation" width="1" height="1" /></p> <p><a href="https://theconversation.com/profiles/matthew-griffith-1539353"><em>Matthew Griffith</em></a><em>, Associate Professor and ARC Future Fellow and Director, UniSA Microscopy and Microanalysis Facilities, <a href="https://theconversation.com/institutions/university-of-south-australia-1180">University of South Australia</a></em></p> <p><em>Image credits: Shutterstock </em></p> <p><em>This article is republished from <a href="https://theconversation.com">The Conversation</a> under a Creative Commons license.

John Farnham tells all about gruelling surgery and recovery

<p>John Farnham has candidly shared the details of his mammoth surgery to remove a cancerous tumour from his jaw, and the subsequent recovery process. </p> <p>Revealing all in his new memoir <em>The Voice Inside</em>, the Aussie music legend spoke about his recent health challenges after he was diagnosed with oral cancer in August 2022 which saw him undergo a marathon 12-hour surgery to the tumour. </p> <p>The procedure involved the reconstruction of part of his jaw and required intensive care and an extended recovery period, as surgeons removed all his bottom teeth and scraped his jaw bone.</p> <p>Farnham’s recounting of the experience in his memoir, marking the first time the music legend has talked publicly about the surgery and his recovery.</p> <p>“I was told later that someone from the medical team called Jillian [Billman, Farnham’s wife] a couple of times while I was in theatre – apparently I was very close to dying,” he said.</p> <p>He went on to write about the lengthy journey of finding his voice again, writing, “My facial disfigurement from the surgery means I can’t open my mouth wide enough for a strip of spaghetti, let alone to sing a top C."</p> <p>"At this stage I can’t get the movement to make the sounds I want to make, and that’s where the vibrations and my voice come from,” he wrote.</p> <p>“It’s still a very disconcerting thing. And trying hurts [...] I can barely open my mouth but I still wail in the shower.”</p> <p>Farnham's memoir comes after his long-time friend Gaynor Wheatley told <em>Today</em> that he has not ruled out the possibility of ever <a href="https://oversixty.com.au/health/caring/longtime-friend-opens-up-on-john-farnham-s-potential-return-to-singing" target="_blank" rel="noopener">performing</a> again. </p> <p>"As soon as I saw him in the studio doing the audiobook and as soon as he got behind the microphone, the twinkle was in the eye," she told the show on Wednesday. </p> <p>"That's when I thought, you know, we're still in with a shot and he can still sing, his voice box is still great, there's just a few more things to do with the mouth recovery, but we all know he's as strong as a boxer so if he wants to do something, he'll do it.</p> <p>"If I say to him, 'You won't sing, you can't sing, what a shame', then he'll go, 'Yes I can, I'll prove you wrong'."</p> <p><em>Image credits: Getty Images / Facebook</em></p>

How to rewire your brain to feel good on Monday

<div class="theconversation-article-body"> <p><em><a href="https://theconversation.com/profiles/cristina-r-reschke-1413051">Cristina R. Reschke</a>, <a href="https://theconversation.com/institutions/rcsi-university-of-medicine-and-health-sciences-788">RCSI University of Medicine and Health Sciences</a> and <a href="https://theconversation.com/profiles/jolanta-burke-315263">Jolanta Burke</a>, <a href="https://theconversation.com/institutions/rcsi-university-of-medicine-and-health-sciences-788">RCSI University of Medicine and Health Sciences</a></em></p> <p>If you hate Mondays, you’re most certainly in good company. After a couple of days off, many of us have difficulty settling back into our routines and work duties. You may even have dread and anxiety that seeps into the weekend in the form of “<a href="https://theconversation.com/three-ways-to-tackle-the-sunday-scaries-the-anxiety-and-dread-many-people-feel-at-the-end-of-the-weekend-187313">Sunday scaries</a>”.</p> <p>You can’t always change your schedule or obligations to make Mondays more appealing, but you may be able to “reprogram” your brain to think about the week differently.</p> <p>Our brains love predictability and routine. Research has shown that lack of routine is associated with <a href="https://journals.sagepub.com/doi/full/10.1177/0003122418823184">decline in wellbeing and psychological distress</a>. Even though the weekend heralds a leisurely and pleasant time, our brain works hard to adjust to this sudden change to a routine.</p> <p>The good news is that the brain does not need to make too much effort when adjusting to the weekend’s freedom and lack of routine. However, it’s a different story when coming back to the less pleasant activities, such as a to-do list on Monday morning.</p> <p>One way to adjust to post-weekend change is introducing routines that last the whole week and have the power to make our lives <a href="https://journals.sagepub.com/doi/full/10.1177/0146167218795133">more meaningful</a>. These may include <a href="https://portal.research.lu.se/en/publications/routines-made-and-unmade">watching your favourite TV programme, gardening</a> or going <a href="https://pubmed.ncbi.nlm.nih.gov/22976286/">to the gym</a>. It is helpful to do these things at the same time every day.</p> <p>Routines improve our <a href="https://pubmed.ncbi.nlm.nih.gov/16448317/">sense of coherence</a>, a process that allows us to make sense of the jigsaw of life events. When we have an established routine, be it the routine of working five days and taking two days off or engaging in a set of actions every day, our lives become <a href="https://journals.sagepub.com/doi/full/10.1177/0146167218795133">more meaningful</a>.</p> <p>Another important routine to establish is your sleep routine. <a href="https://www.nature.com/articles/s41746-021-00400-z">Research shows</a> that keeping consistent sleep time may be as important for enjoying Mondays as how long your sleep lasts or its quality.</p> <p>Changes in sleep patterns during weekends trigger <a href="https://www.mdpi.com/2072-6643/13/12/4543">social jetlag</a>. For instance, sleeping in later than usual and for longer on free days may trigger a discrepancy between your body clock and socially-imposed responsibilities. This is linked to higher stress levels on Monday morning.</p> <p>Try to keep a set time for going to bed and waking up, avoid naps. You might also want to create a 30 minute “wind-down” routine before sleep, by turning off or putting away your digital devices and practising relaxation techniques.</p> <h2>Hacking your hormones</h2> <p>Hormones can also play a role in how we feel about Mondays. For instance, cortisol is a very important multifunction hormone. It helps our bodies to control our metabolism, regulate our sleep-wake cycle and our response to stress, among other things. It is usually released about an hour before we wake up (it helps us feel awake) and then its levels lower until the next morning, unless we’re under stress.</p> <p>Under acute stress, our bodies release not only cortisol, but also adrenaline in preparation for fight or flight. This is when the heart beats fast, we get sweaty palms and may react impulsively. This is our amygdala (a small almond-shaped area in the base of our brains) hijacking our brains. It creates a super fast emotional response to stress even before our brains can process and think whether it was needed.</p> <p>But as soon we can think – activating the brain’s prefrontal cortex, the area for our reason and executive thinking – this response will be mitigated, if there is no real threat. It is a constant battle between our emotions and reason. This might wake us up in the middle of the night when we’re too stressed or anxious.</p> <p>It shouldn’t be surprising then that cortisol levels, measured in saliva samples of full-time working individuals, tend to be higher on Mondays and Tuesdays, with the lowest levels reported on <a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC2824866/">Sundays</a>.</p> <p>As a stress hormone, cortisol fluctuates daily, but not consistently. On weekdays, as soon as we wake up, <a href="https://psycnet.apa.org/record/2007-18151-008">cortisol levels soar</a> and variations tend to be higher than on <a href="https://pubmed.ncbi.nlm.nih.gov/11324714/">weekends</a>.</p> <p>To combat this, we need to trick the amygdala by training the brain to only recognise actual threats. In other words, we need to activate our prefrontal cortex as fast as possible.</p> <p>One of the best ways to achieve this and lower overall stress is through relaxation activities, especially on Mondays. One possibility is mindfulness, which is associated with a <a href="https://pubmed.ncbi.nlm.nih.gov/23724462/">reduction in cortisol</a>. <a href="https://www.frontiersin.org/articles/10.3389/fpsyg.2019.00722/full">Spending time in nature</a> is another method – going outside first thing on Monday or even during your lunch hour can make a significant difference to how you perceive the beginning of the week.</p> <p>Give yourself time before checking your phone, social media and the news. It’s good to wait for cortisol peak to decrease naturally, which happens approximately one hour after waking up, before you expose yourself to external stressors.</p> <p>By following these simple tips, you can train your brain to believe that the weekdays can be (nearly) as good as the weekend.<img style="border: none !important; box-shadow: none !important; margin: 0 !important; max-height: 1px !important; max-width: 1px !important; min-height: 1px !important; min-width: 1px !important; opacity: 0 !important; outline: none !important; padding: 0 !important;" src="https://counter.theconversation.com/content/199236/count.gif?distributor=republish-lightbox-basic" alt="The Conversation" width="1" height="1" /></p> <p><a href="https://theconversation.com/profiles/cristina-r-reschke-1413051"><em>Cristina R.

Channel Nine star shares "alarming" hospital photos

<p>Channel Nine star Leila McKinnon has shared a series of "alarming" photos from a hospital bed after undergoing surgery. </p> <p>The veteran newsreader revealed in a candid Instagram post on Thursday that she’d undergone “another delightful knee operation”, which had left her leg a startling shade of pink.</p> <p>“I may or may not be high as a kite right now after another delightful knee operation, but something alarming appears to have happened, is my leg pink?” McKinnon wrote alongside the images.</p> <p>“Surgical team did play some brilliant Chappell Roan tunes for me.”</p> <p>The mother-of-two, who is married to former Nine CEO David Gyngell, explained in the comments that the colour had come from a post-op disinfectant after her followers expressed their concerns. </p> <p>It’s understood McKinnon had undergone the operation to remove a pin inserted after an accident in 2022 which had seen her rushed to hospital.</p> <p>She posted a picture from her hospital bed along with X-rays of the injury at the time, along with a caption explaining that the injury was a result of a skiing accident. </p> <p>“Hey what did you do on the school holidays? I don’t want to show off or anything but I got a fancy piercing in my knee …” McKinnon said at the time. </p> <p><em>Image credits: Instagram </em></p>

Breakthrough study finds genetic link to Parkinson's and ADHD

<p>A major scientific study has found a surprising link between the genes that control brain size and the risk of brain-related conditions. </p> <p>A Queensland Institute of Medical Research Associate Professor Miguel Renteria led an international team of experts who scanned DNA data and MRI scans from 76,000 participants.</p> <p>“Genetic variants associated with larger brain volumes in key brain regions also increase the risk of Parkinson’s disease, while variants linked to smaller brain volumes in key regions are associated with an increased risk of ADHD,” Renteria said. </p> <p>“It brings us closer to answering key questions about how genetics influence brain structure, and how we can potentially treat these conditions in future.”</p> <p>Parkinson’s Australia CEO Olivia Nassaris has celebrated the results of the study, saying the surprising results open the door to future treatment options for Parkinson’s, which currently has no cure or cause.</p> <p>“The more answers we have the closer we are to understanding this condition,” she said.</p> <p>Michael Wiseman, who has been living with Parkinson’s for eight years, said he is pleased more research is being done about the neurodegenerative condition.</p> <p>“I know it’s not going to benefit me in any way, as far as a cure or anything … I just hope they keep going, kicking some goals and finding results because it’s an insidious sort of thing, it’s a passenger I’ll have until I go to the grave.”</p> <p><em>Image credits: Shutterstock </em></p>

Retiring early can be bad for the brain

<div class="theconversation-article-body"><em><a href="https://theconversation.com/profiles/plamen-v-nikolov-1112610">Plamen V Nikolov</a>, <a href="https://theconversation.com/institutions/binghamton-university-state-university-of-new-york-2252">Binghamton University, State University of New York</a></em></p> <p><em>The <a href="https://theconversation.com/us/topics/research-brief-83231">Research Brief</a> is a short take about interesting academic work.</em></p> <h2>The big idea</h2> <p>People who retire early suffer from accelerated cognitive decline and may even encounter early onset of dementia, according to a I conducted with my doctoral student <a href="https://sites.google.com/binghamton.edu/alan-adelman/home">Alan Adelman</a>.</p> <p>To establish that finding, we examined the effects of a rural pension program China introduced in 2009 that provided people who participated with a stable income if they stopped working after the official retirement age of 60. We found that people who participated in the program and retired within one or two years experienced a cognitive decline equivalent to a drop in general intelligence of 1.7% relative to the general population. This drop is equivalent to about three IQ points and could make it harder for someone to <a href="https://doi.org/10.1017/S0033291700008412">adhere to a medication schedule</a> or <a href="https://doi.org/10.1111/j.1475-%205890.2007.00052.x">conduct financial planning</a>. The largest negative effect was in what is called “delayed recall,” which measures a person’s ability to remember something mentioned several minutes ago. Neurological research <a href="https://doi.org/10.1001/archneur.1991.00530150046016">links problems in this area to an early onset of dementia</a>.</p> <h2>Why it matters</h2> <p>Cognitive decline refers to when a person has trouble remembering, learning new things, concentrating or making decisions that affect their everyday life. Although some cognitive decline appears to be an inevitable byproduct of aging, faster decline can have profound adverse consequences on one’s life.</p> <p>Better understanding of the causes of this has powerful financial consequences. Cognitive skills – the mental processes of gathering and processing information to solve problems, adapt to situations and learn from experiences – are crucial for decision-making. They influence an individual’s ability to process information and <a href="https://www.jstor.org/stable/1818642">are connected to higher earnings</a> and a <a href="https://www.doi.org/10.1257/jep.25.1.159">better quality of life</a>.</p> <p>Retiring early and working less or not at all can generate large benefits, such as reduced stress, better diets and more sleep. But as we found, it also has unintended adverse effects, like fewer social activities and less time spent challenging the mind, that far outweighed the positives.</p> <p>While retirement schemes like the 401(k) and similar programs in other countries <a href="https://www.doi.org/10.1023/B:PUCH.0000035859.20258.e0">are typically introduced to ensure the welfare of aging adults</a>, our research suggests they need to be designed carefully to avoid unintended and significant adverse consequences. When people consider retirement, they should weigh the benefits with the significant downsides of a sudden lack of mental activity. A good way to ameliorate these effects is to stay engaged in social activities and continue to use your brains in the same way you did when you were working.</p> <p>In short, we show that if you rest, you rust.</p> <h2>What still isn’t known</h2> <p>Because we are using data and a program in China, the mechanisms of how retirement induces cognitive decline could be context-specific and may not necessarily apply to people in other countries. For example, cultural differences or other policies that can provide support to individuals in old age can buffer some of the negative effects that we see in rural China due to the increase in social isolation and reduced mental activities.</p> <p>Therefore, we can not definitively say that the findings will extrapolate to other countries. We are looking for data from other countries’ retirement programs, such as India’s, to see if the effects are similar or how they are different.</p> <h2>How I do my research</h2> <p>A big focus of the <a href="https://scholar.harvard.edu/pnikolov/my-research-group-1">economics research lab</a> I run is to <a href="http://www.nber.org/%7Enikolovp/research.html">better understand</a> the causes and consequences of changes in what economists call <a href="https://www.britannica.com/topic/human-capital">“human capital”</a> – especially cognitive skills – in the context of developing countries.</p> <p>Our lab’s mission is to generate research to inform economic policies and empower individuals in low-income countries to rise out of poverty. One of the main ways we do this is through the use of randomized controlled trials to measure the impact of a particular intervention, such as retiring early or access to microcredit, on education outcomes, productivity and health decisions.</p> <p><a href="https://theconversation.com/profiles/plamen-v-nikolov-1112610"><em>Plamen V Nikolov</em></a><em>, Assistant Professor of Economics, <a href="https://theconversation.com/institutions/binghamton-university-state-university-of-new-york-2252">Binghamton University, State University of New York</a></em></p> <p><em>Image credits: Shutterstock</em></p> <p><em>This article is republished from <a href="https://theconversation.com">The Conversation</a> under a Creative Commons license.

John Farnham's voice heard for the first time since throat surgery

<p>John Farnham's voice has been heard for the first time since undergoing extensive surgery on his throat and jaw to treat his cancer in August 2022. </p> <p>The Aussie music legend is lending his voice to narrate the audio version of his new <a href="https://oversixty.com.au/health/caring/finally-felt-like-the-right-time-john-farnham-s-huge-announcement" target="_blank" rel="noopener">memoir</a> titled <em>The Voice Inside</em>, which is to be released on October 30th. </p> <p><em>The Morning Show</em>'s entertainment reporter Peter Ford broke the news that Farnham's voice would be heard for the first time in over two years, while playing an exclusive clip from the audio book. </p> <p>Ford said Farnham co-wrote the book with Poppy Stockwell, who directed his recent Logie-winning documentary <em>The Voice Inside</em>, saying the documentary was “brilliantly done,” and “obviously John feels safe and a great connection with her”.</p> <p>“So they’ve written it together now," Ford said. </p> <p>“We got the news that John was going to do the audio version of the book, and also his wife Jill will actually be writing two chapters.”</p> <blockquote class="instagram-media" style="background: #FFF; border: 0; border-radius: 3px; box-shadow: 0 0 1px 0 rgba(0,0,0,0.5),0 1px 10px 0 rgba(0,0,0,0.15); margin: 1px; max-width: 540px; min-width: 326px; padding: 0; width: calc(100% - 2px);" data-instgrm-permalink="https://www.instagram.com/reel/DA17RsMNCTK/?utm_source=ig_embed&utm_campaign=loading" data-instgrm-version="14"> <div style="padding: 16px;"> <div style="display: flex; flex-direction: row; align-items: center;"> <div style="background-color: #f4f4f4; border-radius: 50%; flex-grow: 0; height: 40px; margin-right: 14px; width: 40px;"> </div> <div style="display: flex; flex-direction: column; flex-grow: 1; justify-content: center;"> <div style="background-color: #f4f4f4; border-radius: 4px; flex-grow: 0; height: 14px; margin-bottom: 6px; width: 100px;"> </div> <div style="background-color: #f4f4f4; border-radius: 4px; flex-grow: 0; height: 14px; width: 60px;"> </div> </div> </div> <div style="padding: 19% 0;"> </div> <div style="display: block; height: 50px; margin: 0 auto 12px; width: 50px;"> </div> <div style="padding-top: 8px;"> <div style="color: #3897f0; font-family: Arial,sans-serif; font-size: 14px; font-style: normal; font-weight: 550; line-height: 18px;">View this post on Instagram</div> </div> <div style="padding: 12.5% 0;"> </div> <div style="display: flex; flex-direction: row; margin-bottom: 14px; align-items: center;"> <div> <div style="background-color: #f4f4f4; border-radius: 50%; height: 12.5px; width: 12.5px; transform: translateX(0px) translateY(7px);"> </div> <div style="background-color: #f4f4f4; height: 12.5px; transform: rotate(-45deg) translateX(3px) translateY(1px); width: 12.5px; flex-grow: 0; margin-right: 14px; margin-left: 2px;"> </div> <div style="background-color: #f4f4f4; border-radius: 50%; height: 12.5px; width: 12.5px; transform: translateX(9px) translateY(-18px);"> </div> </div> <div style="margin-left: 8px;"> <div style="background-color: #f4f4f4; border-radius: 50%; flex-grow: 0; height: 20px; width: 20px;"> </div> <div style="width: 0; height: 0; border-top: 2px solid transparent; border-left: 6px solid #f4f4f4; border-bottom: 2px solid transparent; transform: translateX(16px) translateY(-4px) rotate(30deg);"> </div> </div> <div style="margin-left: auto;"> <div style="width: 0px; border-top: 8px solid #F4F4F4; border-right: 8px solid transparent; transform: translateY(16px);"> </div> <div style="background-color: #f4f4f4; flex-grow: 0; height: 12px; width: 16px; transform: translateY(-4px);"> </div> <div style="width: 0; height: 0; border-top: 8px solid #F4F4F4; border-left: 8px solid transparent; transform: translateY(-4px) translateX(8px);"> </div> </div> </div> <div style="display: flex; flex-direction: column; flex-grow: 1; justify-content: center; margin-bottom: 24px;"> <div style="background-color: #f4f4f4; border-radius: 4px; flex-grow: 0; height: 14px; margin-bottom: 6px; width: 224px;"> </div> <div style="background-color: #f4f4f4; border-radius: 4px; flex-grow: 0; height: 14px; width: 144px;"> </div> </div> <p style="color: #c9c8cd; font-family: Arial,sans-serif; font-size: 14px; line-height: 17px; margin-bottom: 0; margin-top: 8px; overflow: hidden; padding: 8px 0 7px; text-align: center; text-overflow: ellipsis; white-space: nowrap;"><a style="color: #c9c8cd; font-family: Arial,sans-serif; font-size: 14px; font-style: normal; font-weight: normal; line-height: 17px; text-decoration: none;" href="https://www.instagram.com/reel/DA17RsMNCTK/?utm_source=ig_embed&utm_campaign=loading" target="_blank" rel="noopener">A post shared by The Morning Show On 7 (@morningshowon7)</a></p> </div> </blockquote> <p>Ford expressed his excitement over the clip, saying, “This is for the first time now in many years.”</p> <p>“We haven’t heard John.

Jimmy Barnes shares positive update after surgery

<p>Jimmy Barnes has shared a heartwarming update on his health following his emergency hip surgery in August. </p> <p>While on the New Zealand leg of his tour in early August, the 68-year-old rockstar was taken to <a href="https://oversixty.com.au/health/caring/bad-news-jimmy-barnes-reveals-shocking-health-update" target="_blank" rel="noopener">hospital</a> after complaining of "unbearable pain", telling his fans, "The doctors have recommended a remedial medical procedure ASAP followed by some physio to address the issue."</p> <p>Now back at home with his family, Barnes shared that he is on the road to recovery with an update on his healing journey. </p> <p>Barnes said he has had his PICC line, a thin tube inserted through a vein in your arm to deliver medications and treatments directly to the larger veins near your heart, finally removed, meaning he can gain back some normalcy.</p> <p>Barnes said was living with a PICC line in his arm for the past six weeks to continue his treatment as an out patient.</p> <p>“It’s meant that I could leave hospital and continue most of my recovery at home,” he said on Instagram on Friday.</p> <p>“It’s been restricting and liberating at the same time."</p> <p>“This part of my recovery is now over and with the help of (doctors), nurses, physiotherapists, family, friends, you guys and my Jane, everything is on track.”</p> <p>Posing in front of a calendar with Cold Chisel dates, Barnes said rehearsing with the band again this week has “topped things off”.</p> <p>“I can even get back behind the wheel,” he said. “Aah! FREEDOM.”</p> <p><em>Image credits: Instagram</em></p>

The best exercises to boost your brain health after 60

<div class="theconversation-article-body"><em><a href="https://theconversation.com/profiles/neva-beraud-peigne-1418228">Neva Béraud-Peigné</a>, <a href="https://theconversation.com/institutions/universite-paris-saclay-2174">Université Paris-Saclay</a>; <a href="https://theconversation.com/profiles/alexandra-perrot-1531671">Alexandra Perrot</a>, <a href="https://theconversation.com/institutions/universite-paris-saclay-2174">Université Paris-Saclay</a>, and <a href="https://theconversation.com/profiles/pauline-maillot-1167901">Pauline Maillot</a>, <a href="https://theconversation.com/institutions/universite-paris-cite-4263">Université Paris Cité</a></em></p> <p>Have you ever thought about why we have a <a href="https://theconversation.com/fr/topics/cerveau-21903">brain</a>? The obvious answer might be “to think”. But scientist Daniel Wolpert came up with a completely different explanation at the <a href="https://www.ted.com/talks/daniel_wolpert_the_real_reason_for_brains">2011 meeting of the <em>Society for Neuroscience</em></a>:</p> <blockquote> <p>“We have a brain for one reason and one reason only: to produce adaptable and complex movements”</p> </blockquote> <h2>Use your brain to stay efficient</h2> <p>The brain, in other words, is the orchestra conductor which orders the body’s movements. We call the faculties that allow us to interact with our environment <em>cognitive abilities</em>. These include concentrating, learning, reasoning, adapting and communicating with others. Every one of them is key in enabling us to go about our routine and help us maintain a good lifestyle.</p> <p>So, how can we best take care of our brains so that they can stay as efficient as long as possible? Contrary to popular belief, the brain does not deteriorate continuously with age. Instead, it only sees the number of its brain cells drop and connections deteriorate <a href="https://www.bmj.com/content/344/bmj.d7622">from the age of 45 onwards</a> as part of a normal ageing process. But cerebral plasticity, although reduced, is present until the end of life. Each individual will build up a cognitive reserve throughout their lives.</p> <p>The more positive, rich and stimulating the lifestyle, the more powerful and effective the reserve. In other words, it’s possible to moderate the effects of age on cognition.</p> <h2>The benefits of physical activity on cognitive capacity after 60</h2> <p>In fact, much research shows indeed that physical activity improves cognitive capacity, even after the age of 60. From increased memory, better reactivity to greater planning skills, the <a href="https://www.annualreviews.org/content/journals/10.1146/annurev-clinpsy-072720-014213">benefits are endless</a>.</p> <p>Despite this, few older folks engage in <a href="https://theconversation.com/fr/topics/activite-physique-adaptee-apa-146288">physical education</a> adapted to their bodies on a regular basis. Poor motivation and access to these exercises are some of the factors don’t help.</p> <p>With that in mind, many carers might be tempted to offer older people monotonous, routine activities because of their diminishing physical, cognitive and sensory abilities. And indeed, for a long time, the range of sports on offer and research in this field revolved around the same triptych: gentle gymnastics, walking and yoga. However, you’ll reap more benefits by <a href="https://www-sciencedirect-com.ezproxy.u-paris.fr/science/article/abs/pii/B9780444633279000175">combining different training methods</a>.</p> <h2>Three ingredients to train the brains of senior citizens</h2> <p>Researchers are currently attempting to crack the winning formula that would flex older people’s cognitive, as well as physical muscles. It’ll consist of three main ingredients:</p> <p><em>First ingredient: complex physical and motor stimulation of at least moderate intensity.</em></p> <p>Moderate cardio workouts not only improve cardiorespiratory health but also make the brain more <a href="https://www.nature.com/articles/22682">efficient</a>. Overall improved cardiofitness, in turn, allows the brain to receive more oxygen and even to generate <a href="https://www.pnas.org/doi/full/10.1073/pnas.1015950108">new neurons in the hippocampus</a>, where memory is lodged.</p> <p>It therefore makes sense for programmes designed to boost cognitive function to include cardio. But it is also <a href="https://journals.sagepub.com/doi/abs/10.1111/1467-9280.t01-1-01430">necessary to combine them with muscle-strengthening, flexibility and balance exercises to achieve greater benefits</a>. In addition, the <a href="https://www.sciencedirect.com/science/article/abs/pii/S0149763413001012">researchers</a> emphasise the importance of adding situations requiring complex motor skills and coordination, as these would have a significant impact on cognitive functions (e.g. memory, attention and mental flexibility), particularly in the elderly.</p> <p><em>Second ingredient: fire up those brain cells during exercises</em></p> <p>Incorporating cognitive stimulation, such as remembering information for a period of time and executing it, anticipating actions, or planning a move, is another winning strategy. When cognitive stimulation is combined with physical activity, it can produce <a href="https://www.tandfonline.com/doi/abs/10.1080/13825585.2011.645010">synergistic effects</a> and, as a result, be more effective on cognitive functions.</p> <p>_Third ingredient: group activities that lead to social interaction. _</p> <p>Working out as part of a group has been shown to help us <a href="https://journals.plos.org/plosmedicine/article?id=10.1371/journal.pmed.1001756">persevere through it</a>.</p> <p>What this winning formula could look like in practice is still being researched. At present, there are two broad types of exercises that have caught our attention that could help older people stay sharp.</p> <h2>Opting for cooperative and oppositional team sports</h2> <p>Team sports offer much more than just physical exercise sessions. What’s particularly great about them is that they don’t only challenge cardiorespiratory balance, but tap into the whole body’s physical skill-set.</p> <p>Take basketball or handball, for example: to move around the court, dribble or score, balance, coordination and flexibility are essential. Muscular strength is also required for passing, recovering the ball and moving around. These team sports can be suitable even after the age of 60, provided they are properly supervised.</p> <p>From a cognitive point of view, these activities create situations that are always new, rich and stimulating. We call this double combination of stimuli <em><a href="https://www.tandfonline.com/doi/abs/10.1080/13825585.2011.645010">simultaneous training</a></em>. A number of researchers have highlighted the importance of this cognitive involvement in team sports and encourage their practice, particularly among the elderly.</p> <p>Recent studies, such as <a href="https://linkinghub.elsevier.com/retrieve/pii/S162748302100129X">the one carried out in 2022</a> by French researchers, have shown that participation in team sports improves short-term visuospatial memory (which enables people, for example, to remember the location of certain objects for a limited period of time) and planning skills in the elderly.</p> <h2>Get your body moving with exergames</h2> <p>Another promising avenue are <em>exergames</em> – video games that require players to move around to play. Named after the contraction of “exercise” and “games”, they grew popular in the 2000s thanks to Nintendo’s Wii and Switch and Microsoft’s Kinect.</p> <p>Exogames have been thought out to exercise different fitness skills, such as balance, endurance, strength, and coordination, while simultaneously stimulating cognitive functions. Among older people, <a href="https://psycnet.apa.org/record/2011-27707-001">several research studies</a> show that this type of training helps to improve many physical and cognitive abilities.</p> <p>In 2020, a new generation of exergames emerged, making use of interactive walls to create an even more immersive gaming experience, such as Neo Xperiences’ <em>Neo-One</em>, Sphery’s <em>ExerCube</em> and Lü’s <em>Aire interactive</em>. In these games combining real and virtual worlds, physical objects (such as balls) and digital objects coexist and interact in real time.</p> <p>A <a href="https://link.springer.com/article/10.1007/s11357-023-00952-w">recent study</a> compared an exergame programme assisted by an immersive wall with a walking and muscle-strengthening programme. Its results suggest that this new generation of exergames may be more effective on cognitive abilities than traditional training.</p> <p>Combining physical and cognitive exercises offers the best chance to keep one’s brain health while keeping fit. This is essential for an active and fulfilling life, whatever your age.<img style="border: none !important; box-shadow: none !important; margin: 0 !important; max-height: 1px !important; max-width: 1px !important; min-height: 1px !important; min-width: 1px !important; opacity: 0 !important; outline: none !important; padding: 0 !important;" src="https://counter.theconversation.com/content/237162/count.gif?distributor=republish-lightbox-basic" alt="The Conversation" width="1" height="1" /></p> <p><em><a href="https://theconversation.com/profiles/neva-beraud-peigne-1418228">Neva Béraud-Peigné</a>, Doctorante en sciences du mouvement, <a href="https://theconversation.com/institutions/universite-paris-saclay-2174">Université Paris-Saclay</a>; <a href="https://theconversation.com/profiles/alexandra-perrot-1531671">Alexandra Perrot</a>, Maitre de conférences HDR, <a href="https://theconversation.com/institutions/universite-paris-saclay-2174">Université Paris-Saclay</a>, and <a href="https://theconversation.com/profiles/pauline-maillot-1167901">Pauline Maillot</a>, Maître de conférences en STAPS, <a href="https://theconversation.com/institutions/universite-paris-cite-4263">Université Paris Cité</a></em></p> <p><em>Image credits: Shutterstock </em></p> <p><em>This article is republished from <a href="https://theconversation.com">The Conversation</a> under a Creative Commons license.

Do mobile phones cause brain cancer? Science makes definitive call

<p>The question of whether mobile phones - specifically the electromagnetic radiation or radio waves emitted by these devices - cause cancer has been debated and researched for a long time, and now scientists have made a definitive call. </p> <p>A new comprehensive review commissioned by the World Health Organization has found that mobile phones are NOT linked to brain and head cancers. </p> <p>The systematic review, led by the Australian Radiation Protection and Nuclear Safety Agency (Arpansa), examined over 5,000 studies, which included 63 observational studies on humans published between 1994 and 2022 and is "the most comprehensive review to date" according to review lead author, associate prof Ken Karipidis. </p> <p>“We concluded the evidence does not show a link between mobile phones and brain cancer or other head and neck cancers," he said. </p> <p>The review, which was published on Wednesday, focused on cancers of the nervous system, salivary gland and brain tumours. </p> <p>They found no overall association between mobile phone use and cancer, even if people have used it for a long time (over 10 years) or spend a lot of time on their phones. </p> <p>“I’m quite confident with our conclusion. And what makes us quite confident is … even though mobile phone use has skyrocketed, brain tumour rates have remained stable,” Karipidis continued. </p> <p>Despite emitting electromagnetic radiation, also known as radio waves, the exposure is relatively low. </p> <p>Karipidis said people hear the word radiation and assume it is similar to nuclear radiation, “and because we use a mobile phone close to the head when we’re making calls, there is a lot of concern.”</p> <p>He clarified that “radiation is basically energy that travels from one point to another. There are many different types, for example, ultraviolet radiation from the sun." </p> <p>“We’re always exposed to low-level radio waves in the everyday environment.”</p> <p>While exposure from mobile phones is still low, it is much higher than exposure from any other wireless technology sources since they are used close to the head, Karipidis said. </p> <p>The association between mobile phones and cancers came about from early studies comparing differences between those with and without brain tumours and asking about their exposure history. </p> <p>According to Karipidis, who is also the vice-chair of the International Commission on Non-Ionizing Radiation Protection, the results from these kind of studies tend to be biased, as the group with the tumour tend to overreport their exposure. </p> <p>Based on these early studies WHO’s International Agency for Research on Cancer (IARC) designated radio-frequency fields like those from mobile phones as a possible cancer risk, but Karipidis said "this classification doesn’t mean all that much”.</p> <p>This is because the IARC has different classifications of cancer risk, with some substances classified as a “definite” carcinogen (such as smoking), and others as “probable” or “possible” carcinogens.</p> <p>Tim Driscoll, a professor at the University of Sydney and chair of the Australian Cancer Council’s occupational and environmental cancers committee, also backed the systematic review. </p> <p>“I think people should feel reassured by this study … but it’s worthwhile just remembering that the studies aren’t perfect, but the weight of evidence certainly is that mobile phones should be considered safe to use in terms of any concerns about increased risk of cancer,” Driscoll said.</p> <p><em>Images: Shutterstock</em></p> <p> </p>

Can a 10-year-old be responsible for a crime? Here’s what brain science tells us

<div class="theconversation-article-body"><em><a href="https://theconversation.com/profiles/susan-m-sawyer-109573">Susan M. Sawyer</a>, <a href="https://theconversation.com/institutions/the-university-of-melbourne-722">The University of Melbourne</a> and <a href="https://theconversation.com/profiles/nandi-vijayakumar-1644262">Nandi Vijayakumar</a>, <a href="https://theconversation.com/institutions/deakin-university-757"><em>Deakin University</em></a></em></p> <p>The age a child can be arrested, charged and jailed in Australia is back in the spotlight.</p> <p>Last year, the Northern Territory became the first jurisdiction to raise the age of criminal responsibility from ten to 12. Now its new, tough-on-crime government has pledged to <a href="https://www.sbs.com.au/nitv/article/incoming-chief-minister-says-age-of-criminal-responsibility-to-be-lowered-to-10-years-old/a1xm9jy9c">return it to ten</a>. It comes after Victoria <a href="https://www.abc.net.au/news/2024-08-13/victoria-youth-justice-reform-criminal-age/104217160">walked back</a> its earlier commitment to raise the age to 14, settling instead on 12.</p> <p>But the United Nations Committee on the Rights of the Child says 14 should be the absolute <a href="https://www.ohchr.org/en/documents/general-comments-and-recommendations/general-comment-no-24-2019-childrens-rights-child">minimum</a>. It raised this age from its earlier recommendation (in 2007) of 12, citing a decade of new research into child and adolescent development.</p> <p>So what does the science say? What happens to the brain between ten and 14? And how much can those under 14 understand the consequences of their actions?</p> <h2>Who is an adolescent?</h2> <p>Our research shows adolescence is a <a href="https://pubmed.ncbi.nlm.nih.gov/30169257/">critical period</a> for development. It’s the time children’s experiences and explorations shape how they develop cognitive skills (including critical thinking and decision making), as well as social and emotional skills (including moral reasoning).</p> <p>Adolescence also lasts longer than we tend to think. Important brain development begins during late childhood, around eight to nine years. Intense changes then follow during early adolescence (ages ten to 14). But these changes continue well into the twenties, and full cognitive and emotional maturity is not usually reached until around age 24.</p> <p>However, everyone’s brain matures at a different rate. That means there is no definitive age we can say humans reach “adult” levels of cognitive maturity. What we do know is the period of early adolescence is critical.</p> <h2>What does puberty do to the brain?</h2> <p>Puberty is a defining feature of early adolescence. Most of us are familiar with the changes that occur to the body and reproductive systems. But the increase in puberty hormones, such as testosterone and oestrogen, also trigger changes to the brain. These hormones <a href="https://www.sciencedirect.com/science/article/abs/pii/S0306453017313252?via%3Dihub">increase most sharply</a> between ten and 15 years of age, although gradual changes continue into the early twenties.</p> <p>Puberty hormones change the structures in the brain which process emotions, including the amygdala (which encodes fear and stress) and ventral striatum (involved in reward and motivation).</p> <p>This makes adolescents particularly reactive to emotional rewards and threats. <a href="https://doi.org/10.1016/j.cortex.2019.04.024">Our research</a> has shown the brain’s sensitivity to emotions increases throughout early adolescence until around 14 or 15 years old.</p> <p>At the same time, changes in puberty have <a href="http://dx.doi.org/10.1037/pspp0000172">been linked</a> to increased sensation seeking and impulsive behaviours during early adolescence.</p> <p>This context is crucial when we discuss the behaviour of children in the ten to 14 age range. The way their brains change during this period makes them more sensitive and responsive to emotions, and more likely to be seeking experiences that are new and intense.</p> <h2>How do adolescents make decisions?</h2> <p>The emotional context of puberty influences how younger adolescents make decisions and understand their consequences.</p> <p>Decision making relies on several basic cognitive functions, including the brain’s flexibility, memory and ability to control impulses.</p> <p>These cognitive abilities – which together help us consider the consequences of our actions – undergo some of the <a href="https://doi.org/10.1523/JNEUROSCI.1741-13.2013">steepest development</a> between ages ten and 14. By age 15, the ability to make complex decisions has usually <a href="https://doi.org/10.1037/lhb0000315">reached adult maturity</a>.</p> <p>But adolescents at this age remain highly susceptible to emotions. So while their brain may be equipped to make a complex decision, their ability to think through the consequences, weighing up costs and benefits, can be clouded by emotional situations.</p> <p>For example, <a href="https://doi.org/10.1111/cdev.12085">research has shown</a> 13-14 year-olds were more distracted from completing a task and less able to control their behaviour when they viewed images that made them feel negative emotions.</p> <p>The social world of teenagers also has a significant impact on how they make decisions – especially in early adolescence. One study found that while older adolescents (aged 15-18) are more influenced by what adults think when weighing up risk, adolescents aged 12-14 <a href="https://journals.sagepub.com/doi/full/10.1177/0956797615569578">look to other teenagers</a>.</p> <p>Experiments <a href="https://doi.org/10.1177/0272431616648453">have also shown</a> adolescents aged 12-15 make riskier decisions when they are with peers than by themselves. Their brain responses also suggest they experience a greater sense of reward in taking those risks <a href="https://doi.org/10.1093/scan/nsy071">with peers</a>.</p> <h2>How do teens understand the consequences of their actions?</h2> <p>The concept of <a href="https://www.aph.gov.au/About_Parliament/Parliamentary_Departments/Parliamentary_Library/pubs/rp/rp2122/Quick_Guides/MinimumAgeCriminalResponsibility">criminal responsibility</a> is based on whether a person is able to understand their action and know whether it is wrong.</p> <p>Moral reasoning – how people think about right and wrong – depends on the ability to understand another person’s mental state and adopt their perspective. These skills are in development <a href="https://doi.org/10.1016/j.biopsych.2020.09.012">across adolescence</a>.</p> <p>Research suggests it may take more effort for adolescent brains to process <a href="https://doi.org/10.1162/jocn.2009.21121">“social” emotions</a> such as guilt and embarrassment, compared to adults. This is similar when they make <a href="https://doi.org/10.1080/17470919.2014.933714">moral judgements</a>. This evidence suggests teenage brains may have to work harder when considering other people’s intentions and desires.</p> <p>Young adolescents have the cognitive ability to appreciate they made a bad decision, but it is more mentally demanding.

This includes various forms of neurodisability such as acquired brain injury, fetal alcohol spectrum disorder, attention-deficit hyperactivity disorder (ADHD) and intellectual disability, as well as exposure to trauma.</p> <p>Teenagers with neurodevelopmental disorders will likely cope differently with decision making, social pressure, impulse control and risk assessment, and face <a href="https://www.mcri.edu.au/images/research/strategic-collaborations/Flagships/Neurodevelopment/Neurodevelopment_Flagship_Brochure.pdf">extra difficulties</a>.

Jimmy Barnes shares heartwarming health update

<p>Jimmy Barnes has shared a series of heartwarming updates following his emergency hip surgery earlier this month. </p> <p>While on the New Zealand leg of his tour in early August, the 68-year-old rockstar was taken to <a href="https://oversixty.com.au/health/caring/bad-news-jimmy-barnes-reveals-shocking-health-update" target="_blank" rel="noopener">hospital</a> after complaining of "unbearable pain", telling his fans, "The doctors have recommended a remedial medical procedure ASAP followed by some physio to address the issue."</p> <p>Now back at home with his family, Barnes has posted a series of messages to Instagram describing how thrilled he was to be out of hospital.</p> <p>“I can’t tell how great it feels to be back in my own bed, back to our home and the beautiful garden. Of course, being very spoilt,” he said on Monday.</p> <p>Barnes has also now commenced a high-protein diet and continued with his physio, which he said was “getting tougher”.</p> <p>“If I’m to be on a high-protein recovery diet, I’ve come to the right place,” he said of his wife Jane Barnes’ expert cooking skills.</p> <p>“I’m being loaded up with protein and iron to rebuild muscles that I never had,” he explained in an Instagram caption.</p> <p>He also shared a sweet photo with his grandchildren who have been keeping his spirits high during his recovery, writing alongside the photo, "Rosie and Dylan here to cheer me on at the end of the day. The physio is getting tougher and the protein shakes are growing on me. I sure am a lucky guy."</p> <p>When sharing the news of his surgery with his fans, he said, “Providing all goes to plan, I’m expected to make a full recovery in six weeks.”</p> <p><em>Image credits: Instagram </em></p>

Do you have knee pain from osteoarthritis? You might not need surgery. Here’s what to try instead

<div class="theconversation-article-body"><em><a href="https://theconversation.com/profiles/belinda-lawford-1294188">Belinda Lawford</a>, <a href="https://theconversation.com/institutions/the-university-of-melbourne-722">The University of Melbourne</a>; <a href="https://theconversation.com/profiles/giovanni-e-ferreira-1030477">Giovanni E.

It <a href="https://www.aihw.gov.au/reports/chronic-musculoskeletal-conditions/osteoarthritis">costs the economy</a> A$4.3 billion each year.</p> <p>Osteoarthritis commonly <a href="https://pubmed.ncbi.nlm.nih.gov/33560326/">affects</a> the knees, but can also affect the hips, spine, hands and feet. It impacts the whole joint including bone, cartilage, ligaments and muscles.</p> <p>Most people with osteoarthritis have persistent pain and find it difficult to perform simple daily tasks, such as walking and climbing stairs.</p> <h2>Is it caused by ‘wear and tear’?</h2> <p>Knee osteoarthritis is most likely to affect older people, those who are overweight or obese, and those with previous knee injuries. But contrary to popular belief, knee osteoarthritis is <a href="https://pubmed.ncbi.nlm.nih.gov/31192807/">not caused by</a> “wear and tear”.</p> <p><a href="https://pubmed.ncbi.nlm.nih.gov/21281726/">Research shows</a> the degree of structural wear and tear visible in the knee joint on an X-ray does not correlate with the level of pain or disability a person experiences. Some people have a low degree of structural wear and tear and very bad symptoms, while others have a high degree of structural wear and tear and minimal symptoms. So X-rays are <a href="https://www.safetyandquality.gov.au/standards/clinical-care-standards/osteoarthritis-knee-clinical-care-standard">not required</a> to diagnose knee osteoarthritis or guide treatment decisions.</p> <p>Telling people they have wear and tear can make them worried about their condition and afraid of damaging their joint. It can also encourage them to try invasive and potentially unnecessary treatments such as surgery. We have <a href="https://pubmed.ncbi.nlm.nih.gov/37795555/">shown this</a> in people with osteoarthritis, and other common pain conditions such as <a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC9545091/">back</a> and <a href="https://pubmed.ncbi.nlm.nih.gov/33789444/">shoulder</a> pain.</p> <p>This has led to a global call for a <a href="https://pubmed.ncbi.nlm.nih.gov/38354847/">change in the way</a> we think and communicate about osteoarthritis.</p> <h2>What’s the best way to manage osteoarthritis?</h2> <p>Non-surgical treatments work well for most people with osteoarthritis, regardless of their age or the severity of their symptoms. These <a href="https://www.safetyandquality.gov.au/standards/clinical-care-standards/osteoarthritis-knee-clinical-care-standard">include</a> education and self-management, exercise and physical activity, weight management and nutrition, and certain pain medicines.</p> <p>Education is important to dispel misconceptions about knee osteoarthritis. This includes information about what osteoarthritis is, how it is diagnosed, its prognosis, and the most effective ways to self-manage symptoms.</p> <p>Health professionals who use positive and reassuring language <a href="https://pubmed.ncbi.nlm.nih.gov/35750241/">can improve</a> people’s knowledge and beliefs about osteoarthritis and its management.</p> <p>Many people believe that exercise and physical activity will cause further damage to their joint. But it’s safe and can reduce pain and disability. Exercise has fewer side effects than commonly used pain medicines such as <a href="https://pubmed.ncbi.nlm.nih.gov/36593092/">paracetamol and anti-inflammatories</a> and can <a href="https://pubmed.ncbi.nlm.nih.gov/26488691/">prevent or delay</a> the need for joint replacement surgery in the future.</p> <p>Many types of exercise <a href="https://pubmed.ncbi.nlm.nih.gov/30830561/">are effective</a> for knee osteoarthritis, such as strength training, aerobic exercises like walking or cycling, Yoga and Tai chi. So you can do whatever type of exercise best suits you.</p> <p>Increasing general physical activity is also important, such as taking more steps throughout the day and reducing sedentary time.</p> <p>Weight management is important for those who are overweight or obese. Weight loss <a href="https://pubmed.ncbi.nlm.nih.gov/34843383/">can reduce knee pain and disability</a>, particularly when combined with exercise. Losing as little as 5–10% of your body weight <a href="https://pubmed.ncbi.nlm.nih.gov/36474793/">can be beneficial</a>.</p> <p>Pain medicines should not replace treatments such as exercise and weight management but can be used alongside these treatments to help manage pain. <a href="https://pubmed.ncbi.nlm.nih.gov/33786837/">Recommended medicines</a> include paracetamol and non-steroidal anti-inflammatory drugs.</p> <p>Opioids are <a href="https://pubmed.ncbi.nlm.nih.gov/35137418/">not recommended</a>. The risk of harm outweighs any potential benefits.</p> <h2>What about surgery?</h2> <p>People with knee osteoarthritis commonly undergo two types of surgery: knee arthroscopy and knee replacement.</p> <p>Knee arthroscopy is a type of keyhole surgery used to remove or repair damaged pieces of bone or cartilage that are thought to cause pain.</p> <p>However, high-quality research <a href="https://pubmed.ncbi.nlm.nih.gov/24369076/">has shown</a> arthroscopy is not effective. Arthroscopy should therefore not be used in the management of knee osteoarthritis.</p> <p>Joint replacement involves replacing the joint surfaces with artificial parts. In 2021–22, <a href="https://www.aihw.gov.au/reports/chronic-musculoskeletal-conditions/osteoarthritis">53,500 Australians</a> had a knee replacement for their osteoarthritis.</p> <p>Joint replacement is often seen as being inevitable and “necessary”. But most people can effectively manage their symptoms through exercise, physical activity and weight management.</p> <p>The new guidelines (known as “care standard”) recommend joint replacement surgery only be considered for those with severe symptoms who have already tried non-surgical treatments.</p> <h2>I have knee osteoarthritis.

Australia’s IV fluids shortage will likely last all year. Here’s what that means for surgeries

<div class="theconversation-article-body"><em><a href="https://theconversation.com/profiles/stuart-marshall-1115779">Stuart Marshall</a>, <a href="https://theconversation.com/institutions/the-university-of-melbourne-722"><em>The University of Melbourne</em></a></em></p> <p>The current <a href="https://www.tga.gov.au/about-IV-fluids-shortages">shortage of sterile intravenous (IV) fluids</a> is a serious ongoing concern for doctors across Australia. During surgery, these sterile fluids are essential to administer drugs and hydrate patients intravenously (via the veins).</p> <p>But supplies of two of the most common solutions are critically low.</p> <p>The Australian government has recently moved to <a href="https://www.theguardian.com/australia-news/article/2024/aug/16/australia-iv-fluid-shortage-government-distribution">coordinate supplies</a> of IV fluids to increase manufacturing and ensure distribution. Despite this, supplies are not expected to return to normal levels <a href="https://www.health.gov.au/sites/default/files/2024-08/joint-statement-on-iv-fluids-health-ministers-meeting-16-august-2024.pdf">until the end of the year</a>.</p> <p>So, what will this mean for surgery in Australia? And are there any alternatives?</p> <h2>Why do we need IV fluids for surgery?</h2> <p>IV fluids are used before, during and after surgery to maintain blood volume and the body’s normal functions. They also combat dehydration, which can happen in a number of ways.</p> <p>Before surgery, patients may become dehydrated from illnesses that cause vomiting or diarrhoea. They are also asked to stop eating and drinking for several hours before surgery. This is to minimise the risk of stomach contents being regurgitated and inhaled into the lungs – a <a href="https://my.clevelandclinic.org/health/diseases/21954-aspiration-pneumonia">complication that can cause injury or death</a>. But it can also make them more dehydrated.</p> <p>During surgery, the body continues to lose fluid through normal processes such as sweating and making urine. But some aspects of surgery also exacerbate dehydration, for example, through blood loss or when internal organs are exposed and lose more fluid through evaporation.</p> <p>After the operation, IV fluids may be required for some days. Many patients may still be unable to eat and drink until the function of the gut returns to normal.</p> <p>Multiple research studies, including <a href="https://www.nejm.org/doi/full/10.1056/NEJMoa1801601">a trial </a>of 3,000 patients who underwent major abdominal surgery, have demonstrated the importance of adequate fluid therapy throughout all stages of surgery to avoid kidney damage.</p> <p>Apart from hydration, these sterile fluids – prepared under strict conditions so they contain no bacteria or viruses – are used in surgery for other reasons.</p> <p>Anaesthetists commonly use fluid infusions to slowly deliver medications into the bloodstream. There is some evidence this method of maintaining anaesthesia, compared to inhalation, can improve patients’ experience of “waking up” after the procedure, <a href="https://medcast.com.au/blog/total-intravenous-anaesthesia-tiva">such as being clearer headed and having less nausea and vomiting</a>.</p> <p>Surgeons also use sterile fluids to flush out wounds and surgical sites to prevent infection.</p> <h2>Are there workarounds?</h2> <p>Fluid given intravenously needs to closely resemble the salts in the blood to prevent additional problems. The safest and cheapest options are:</p> <ul> <li>isotonic saline, a solution of water with 0.9% table salt</li> <li>Hartmann’s solution (compound sodium lactate), which combines a range of salts such as potassium and calcium.</li> </ul> <p>Both are <a href="https://www.tga.gov.au/about-IV-fluids-shortages">in short supply</a>.</p> <p>One way to work around the shortage is to minimise how much IV fluid is used during the procedure. This can be achieved by ensuring those admitted to surgery are as well hydrated as possible.</p> <p>Many people presenting for minor surgery can safely drink water up until an hour or so before their operation. A recent initiative termed “<a href="https://associationofanaesthetists-publications.onlinelibrary.wiley.com/doi/10.1111/anae.15855">sip ‘til send</a>” has shown it is safe for patients to drink small amounts of fluid until the operating theatre team “sends” for them from the waiting room or hospital ward.</p> <p>However, this may not be appropriate for those at higher risk of inhaling stomach contents, or patients who take medications including <a href="https://www.journal.acorn.org.au/cgi/viewcontent.cgi?article=1291&context=jpn">Ozempic</a>, which delay the stomach emptying. Patients should follow their anaesthetist’s advice about how to prepare for surgery and when to stop eating and drinking.</p> <p>Large research trials have also helped establish protocols called “<a href="https://www.bjanaesthesia.org/article/S0007-0912(17)53976-8/fulltext">enhanced recovery after surgery</a>”. They show that using special hydrating, carbohydrate-rich drinks before surgery can improve patients’ comfort and speed up healing.</p> <p>These protocols are common in <a href="https://aci.health.nsw.gov.au/__data/assets/pdf_file/0003/736617/ERAS-Key-principles-for-colorectal-surgery.pdf">major bowel surgery</a> in Australia but not used universally. Widespread adoption of these processes may reduce the amount of IV fluids needed during and after large operations, and help patients return to normal eating and drinking earlier. Medications reducing nausea and vomiting are now also routinely administered after surgery to help with this.</p> <h2>What will the shortage mean for surgeries?</h2> <p>The Australian and New Zealand College of Anaesthetists <a href="https://www.anzca.edu.au/news/guidance-on-sparing-of-intravenous-fluid-use">has advised anaesthetists</a> to reduce the consumption of fluid during operations where there might be limited or minimal benefit. This means that the fluid will only be used for people who need it, without a change to the quality and safety of anaesthetic care for any patient.</p> <p>Even with these actions, there is still a chance that some planned surgeries may <a href="https://www.abc.net.au/news/2024-08-15/iv-fluid-shortage-elective-urgery-delays/104225280">need to be postponed</a> in the coming months.</p> <p>If needed, these cancelled operations will likely be ones requiring large volumes of fluid and ones that would not cause unacceptable risks if delayed. Similar to cancellations during the height of the COVID pandemic, emergency operations and surgery for cancers are unlikely to be affected.</p> <p>Monitoring of the supplies and ongoing honest and open dialogue between senior health managers and clinicians will be crucial in minimising the disruption to surgical services.<img style="border: none !important; box-shadow: none !important; margin: 0 !important; max-height: 1px !important; max-width: 1px !important; min-height: 1px !important; min-width: 1px !important; opacity: 0 !important; outline: none !important; padding: 0 !important;" src="https://counter.theconversation.com/content/237009/count.gif?distributor=republish-lightbox-basic" alt="The Conversation" width="1" height="1" /></p> <p><em><a href="https://theconversation.com/profiles/stuart-marshall-1115779">Stuart Marshall</a>, Associate Professor, Department of Critical Care, <a href="https://theconversation.com/institutions/the-university-of-melbourne-722">The University of Melbourne</a></em></p> <p><em>Image credits: Shutterstock </em></p> <p><em>This article is republished from <a href="https://theconversation.com">The Conversation</a> under a Creative Commons license.

"Bad news": Jimmy Barnes reveals shocking health update

<p>Jimmy Barnes has been taken to hospital after complaining of "unbearable pain" while on the New Zealand leg of his tour. </p> <p>The Aussie rock legend took to Instagram to tell his fans that he would be out of action for six weeks after experiencing pain in his hip that requires surgical intervention. </p> <p>"I’ve got some bad news unfortunately," he started the post. "I had a twinge in my hip when I was leaving Dunedin on Thursday morning and by late last night the pain was unbearable so I went off to hospital."</p> <p>"The doctors have recommended a remedial medical procedure ASAP followed by some physio to address the issue.

What happens in my brain when I get a migraine? And what medications can I use to treat it?

<div class="theconversation-article-body"> <p><em><a href="https://theconversation.com/profiles/mark-slee-1343982">Mark Slee</a>, <a href="https://theconversation.com/institutions/flinders-university-972">Flinders University</a> and <a href="https://theconversation.com/profiles/anthony-khoo-1525617">Anthony Khoo</a>, <a href="https://theconversation.com/institutions/flinders-university-972">Flinders University</a></em></p> <p>Migraine is many things, but one thing it’s not is “just a headache”.</p> <p>“Migraine” <a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC1029040/">comes from</a> the Greek word “hemicrania”, referring to the common experience of migraine being predominantly one-sided.</p> <p>Some people experience an “aura” preceding the headache phase – usually a visual or sensory experience that evolves over five to 60 minutes. Auras can also involve other domains such as language, smell and limb function.</p> <p>Migraine is a disease with a <a href="https://www.thelancet.com/journals/laneur/article/PIIS1474-4422(18)30322-3/fulltext">huge personal and societal impact</a>. Most people cannot function at their usual level during a migraine, and anticipation of the next attack can affect productivity, relationships and a person’s mental health.</p> <h2>What’s happening in my brain?</h2> <p>The biological basis of migraine is complex, and varies according to the phase of the migraine. Put simply:</p> <p>The earliest phase is called the <strong>prodrome</strong>. This is associated with activation of a part of the brain called the hypothalamus which is thought to contribute to many symptoms such as nausea, changes in appetite and blurred vision.</p> <figure class="align-center "><img src="https://images.theconversation.com/files/608985/original/file-20240723-17-rgqc7v.jpg?ixlib=rb-4.1.0&q=45&auto=format&w=754&fit=clip" sizes="(min-width: 1466px) 754px, (max-width: 599px) 100vw, (min-width: 600px) 600px, 237px" srcset="https://images.theconversation.com/files/608985/original/file-20240723-17-rgqc7v.jpg?ixlib=rb-4.1.0&q=45&auto=format&w=600&h=485&fit=crop&dpr=1 600w, https://images.theconversation.com/files/608985/original/file-20240723-17-rgqc7v.jpg?ixlib=rb-4.1.0&q=30&auto=format&w=600&h=485&fit=crop&dpr=2 1200w, https://images.theconversation.com/files/608985/original/file-20240723-17-rgqc7v.jpg?ixlib=rb-4.1.0&q=15&auto=format&w=600&h=485&fit=crop&dpr=3 1800w, https://images.theconversation.com/files/608985/original/file-20240723-17-rgqc7v.jpg?ixlib=rb-4.1.0&q=45&auto=format&w=754&h=610&fit=crop&dpr=1 754w, https://images.theconversation.com/files/608985/original/file-20240723-17-rgqc7v.jpg?ixlib=rb-4.1.0&q=30&auto=format&w=754&h=610&fit=crop&dpr=2 1508w, https://images.theconversation.com/files/608985/original/file-20240723-17-rgqc7v.jpg?ixlib=rb-4.1.0&q=15&auto=format&w=754&h=610&fit=crop&dpr=3 2262w" alt="" /><figcaption><span class="caption">The hypothalamus is shown here in red.</span> <span class="attribution"><a class="source" href="https://www.shutterstock.com/image-vector/brain-cross-section-showing-basal-ganglia-329843930">Blamb/Shutterstock</a></span></figcaption></figure> <p>Next is the <strong>aura phase</strong>, when a wave of neurochemical changes occur across the surface of the brain (the cortex) at a rate of 3–4 millimetres per minute. This explains how usually a person’s aura progresses over time. People often experience sensory disturbances such as flashes of light or tingling in their face or hands.</p> <p>In the <strong>headache phase</strong>, the trigeminal nerve system is activated. This gives sensation to one side of the face, head and upper neck, leading to release of proteins such as CGRP (calcitonin gene-related peptide). This causes inflammation and dilation of blood vessels, which is the basis for the severe throbbing pain associated with the headache.</p> <p>Finally, the <strong>postdromal phase</strong> occurs after the headache resolves and commonly involves changes in mood and energy.</p> <h2>What can you do about the acute attack?</h2> <p>A useful way to conceive of <a href="https://www.migraine.org.au/factsheets">migraine treatment</a> is to compare putting out campfires with bushfires. Medications are much more successful when applied at the earliest opportunity (the campfire). When the attack is fully evolved (into a bushfire), medications have a much more modest effect.</p> <p><iframe id="Pj1sC" class="tc-infographic-datawrapper" style="border: 0;" src="https://datawrapper.dwcdn.net/Pj1sC/" width="100%" height="400px" frameborder="0" scrolling="no"></iframe></p> <p><strong>Aspirin</strong></p> <p>For people with mild migraine, non-specific anti-inflammatory medications such as high-dose aspirin, or standard dose non-steroidal medications (NSAIDS) can be very helpful. Their effectiveness is often enhanced with the use of an anti-nausea medication.</p> <p><strong>Triptans</strong></p> <p>For moderate to severe attacks, the mainstay of treatment is a class of medications called “<a href="https://assets.nationbuilder.com/migraineaus/pages/595/attachments/original/1678146819/Factsheet_15_2023.pdf?1678146819">triptans</a>”. These act by reducing blood vessel dilation and reducing the release of inflammatory chemicals.</p> <p>Triptans vary by their route of administration (tablets, wafers, injections, nasal sprays) and by their time to onset and duration of action.</p> <p>The choice of a triptan depends on many factors including whether nausea and vomiting is prominent (consider a dissolving wafer or an injection) or patient tolerability (consider choosing one with a slower onset and offset of action).</p> <p>As triptans constrict blood vessels, they should be used with caution (or not used) in patients with known heart disease or previous stroke.</p> <p><strong>Gepants</strong></p> <p>Some medications that block or modulate the release of CGRP, which are used for migraine prevention (which we’ll discuss in more detail below), also have evidence of benefit in treating the acute attack. This class of medication is known as the “gepants”.</p> <p>Gepants come in the form of injectable proteins (monoclonal antibodies, used for migraine prevention) or as oral medication (for example, rimegepant) for the acute attack when a person has not responded adequately to previous trials of several triptans or is intolerant of them.</p> <p>They do not cause blood vessel constriction and can be used in patients with heart disease or previous stroke.</p> <p><strong>Ditans</strong></p> <p>Another class of medication, the “ditans” (for example, lasmiditan) have been approved overseas for the acute treatment of migraine. Ditans work through changing a form of serotonin receptor involved in the brain chemical changes associated with the acute attack.</p> <p>However, neither the gepants nor the ditans are available through the Pharmaceutical Benefits Scheme (PBS) for the acute attack, so users must pay out-of-pocket, at a <a href="https://www.migraine.org.au/cgrp#:%7E:text=While%20the%20price%20of%20Nurtec,%2D%24300%20per%208%20wafers.">cost</a> of approximately A$300 for eight wafers.</p> <h2>What about preventing migraines?</h2> <p>The first step is to see if <a href="https://assets.nationbuilder.com/migraineaus/pages/595/attachments/original/1677043428/Factsheet_5_2023.pdf?1677043428">lifestyle changes</a> can reduce migraine frequency. This can include improving sleep habits, routine meal schedules, regular exercise, limiting caffeine intake and avoiding triggers such as stress or alcohol.</p> <p>Despite these efforts, many people continue to have frequent migraines that can’t be managed by acute therapies alone. The choice of when to start preventive treatment varies for each person and how inclined they are to taking regular medication. Those who suffer disabling symptoms or experience more than a few migraines a month <a href="https://www.nejm.org/doi/full/10.1056/NEJMra1915327">benefit the most</a> from starting preventives.</p> <p>Almost all migraine <a href="https://assets.nationbuilder.com/migraineaus/pages/595/attachments/original/1708566656/Factsheet_16_2024.pdf?1708566656">preventives</a> have existing roles in treating other medical conditions, and the physician would commonly recommend drugs that can also help manage any pre-existing conditions. First-line preventives include:</p> <ul> <li>tablets that lower blood pressure (candesartan, metoprolol, propranolol)</li> <li>antidepressants (amitriptyline, venlafaxine)</li> <li>anticonvulsants (sodium valproate, topiramate).</li> </ul> <p>Some people have none of these other conditions and can safely start medications for migraine prophylaxis alone.</p> <p>For all migraine preventives, a key principle is starting at a low dose and increasing gradually. This approach makes them more tolerable and it’s often several weeks or months until an effective dose (usually 2- to 3-times the starting dose) is reached.</p> <p>It is rare for noticeable benefits to be seen immediately, but with time these drugs <a href="https://pubmed.ncbi.nlm.nih.gov/26252585/">typically reduce</a> migraine frequency by 50% or more.</p> <hr /> <p><iframe id="jxajY" class="tc-infographic-datawrapper" style="border: 0;" src="https://datawrapper.dwcdn.net/jxajY/" width="100%" height="400px" frameborder="0" scrolling="no"></iframe></p> <hr /> <h2>‘Nothing works for me!’</h2> <p>In people who didn’t see any effect of (or couldn’t tolerate) first-line preventives, new medications have been available on the PBS since 2020. These medications <a href="https://pubmed.ncbi.nlm.nih.gov/8388188/">block</a> the action of CGRP.</p> <p>The most common PBS-listed <a href="https://assets.nationbuilder.com/migraineaus/pages/595/attachments/original/1708566656/Factsheet_16_2024.pdf?1708566656">anti-CGRP medications</a> are injectable proteins called monoclonal antibodies (for example, galcanezumab and fremanezumab), and are self-administered by monthly injections.</p> <p>These drugs have quickly become a game-changer for those with intractable migraines. The convenience of these injectables contrast with botulinum toxin injections (also <a href="https://www.migraine.org.au/botox">effective</a> and PBS-listed for chronic migraine) which must be administered by a trained specialist.</p> <p>Up to half of adolescents and one-third of young adults are <a href="https://deepblue.lib.umich.edu/bitstream/handle/2027.42/147205/jan13818.pdf">needle-phobic</a>.

Pauline Hanson's surprising act of kindness for struggling family

<p>Pauline Hanson has revealed a surprising act of kindness for a struggling Queensland family, who have been battling the private healthcare system. </p> <p>Nine year old Kadee Byrnes, from Yeppoon, about 740km north of Brisbane, has been on the public hospital waiting list for seven years waiting for the adenoid surgery she desperately needs.</p> <p>The surgery is a procedure to remove the adenoids, small tissue lumps in the nasal cavity, to address her chronic tonsillitis.</p> <p>While on the waitlist, Kadee had to repeat the fourth grade after missing so much school due to reoccurring infections. </p> <p>After hearing of Kadee's plight, the One Nation senator said she was "disgusted" the young girl had to wait so long for surgery and promised to cover the cost of her private treatment.</p> <blockquote class="twitter-tweet"> <p dir="ltr" lang="en">Queensland Senator Pauline Hanson has promised to cover the surgery costs for a nine year old Yeppoon girl, who has been on the public hospital waiting list for more than seven years. <a href="https://t.co/WbYeQT6ZHu">https://t.co/WbYeQT6ZHu</a> <a href="https://twitter.com/cpenny_6?ref_src=twsrc%5Etfw">@CPenny_6</a> <a href="https://twitter.com/hashtag/7NEWS?src=hash&ref_src=twsrc%5Etfw">#7NEWS</a> <a href="https://t.co/AdToZNR6Ii">pic.twitter.com/AdToZNR6Ii</a></p> <p>— 7NEWS Central Queensland (@7NewsCQ) <a href="https://twitter.com/7NewsCQ/status/1817847532908912803?ref_src=twsrc%5Etfw">July 29, 2024</a></p></blockquote> <p>"I'm grateful for the opportunity to help 9-year-old Kadee by covering the cost of her private treatment," Ms Hanson said on Tuesday.</p> <p>"It is unacceptable that young Kadee was told she would have to repeat Grade 4 due to missing so many school days because of tonsillitis."</p> <p>"Situations like this are sadly all too common and highlight the severe consequences of the Labor government's lack of investment in our public hospitals, especially outside South East Queensland."</p> <p>Senator Hanson broke the happy news to Kadee's mother, Kahlia, at a speaking event in Roslyn Bay.</p> <p>"Straight away, I said we're going to get this operation done.

Caring

Think you’ve decided what to buy? Actually, your brain is still deciding – even as you put it in your basket

<div class="theconversation-article-body"> <p><em><a href="https://theconversation.com/profiles/tijl-grootswagers-954175">Tijl Grootswagers</a>, <a href="https://theconversation.com/institutions/western-sydney-university-1092">Western Sydney University</a>; <a href="https://theconversation.com/profiles/genevieve-l-quek-1447582">Genevieve L Quek</a>, <a href="https://theconversation.com/institutions/western-sydney-university-1092">Western Sydney University</a>, and <a href="https://theconversation.com/profiles/manuel-varlet-156210">Manuel Varlet</a>, <a href="https://theconversation.com/institutions/western-sydney-university-1092">Western Sydney University</a></em></p> <p>You are standing in the cereal aisle, weighing up whether to buy a healthy bran or a sugary chocolate-flavoured alternative.</p> <p>Your hand hovers momentarily before you make the final grab.</p> <p>But did you know that during those last few seconds, while you’re reaching out, your brain is still evaluating the pros and cons – influenced by everything from your last meal, the health star rating, the catchy jingle in the ad, and the colours of the letters on the box?</p> <p>Our recently published <a href="https://www.nature.com/articles/s41598-024-62135-7">research</a> shows our brains do not just think first and then act. Even while you are reaching for a product on a supermarket shelf, your brain is still evaluating whether you are making the right choice.</p> <p>Further, we found measuring hand movements offers an accurate window into the brain’s ongoing evaluation of the decision – you don’t have to hook people up to expensive brain scanners.</p> <p>What does this say about our decision-making? And what does it mean for consumers and the people marketing to them?</p> <h2>What hand movements tell us about decision-making</h2> <p>There has been <a href="https://www.annualreviews.org/content/journals/10.1146/annurev-psych-010419-051053">debate within neuroscience</a> on whether a person’s movements to enact a decision can be modified once the brain’s “motor plan” has been made.</p> <p>Our research revealed not only that movements can be changed after a decision – “in flight” – but also the changes matched incoming information from a person’s senses.</p> <p>To study <a href="https://doi.org/10.1038/s41598-024-62135-7">how our decisions unfold over time</a>, we tracked people’s hand movements as they reached for different options shown in pictures – for example, in response to the question “is this picture a face or an object?”</p> <p>When choices were easy, their hands moved straight to the right option. But when choices were harder, new information made the brain change its mind, and this was reflected in the trajectory of their hand movements.</p> <p>When we compared these hand movement trajectories to brain activity recorded using neuroimaging, we found that the timing and amount of evidence of the brain’s evaluation matched the movement pattern.</p> <p>Put simply, reaching movements are shaped by ongoing thinking and decision-making.</p> <p>By showing that brain patterns match movement trajectories, our research also highlights that large, expensive brain scanners may not always be required to study the brain’s decision evaluation processes, as movement tracking is much more cost-effective and much easier to test on a large scale.</p> <h2>What does this mean for consumers and marketers?</h2> <p>For consumers, knowing our brains are always reevaluating decisions we might think of as “final” can help us be more aware of our choices.</p> <p>For simple decisions such as choosing a breakfast cereal, the impact may be small. Even if you have preemptively decided on a healthy option, you might be tempted at the last minute by the flashy packaging of a less healthy choice.</p> <p>But for important long-term decisions such as choosing a mortgage, it can have serious effects.</p> <p>On the other side of the coin, marketers have long known that many purchase decisions are <a href="https://www.sciencedirect.com/science/article/pii/S0969698912000781">made on the spot</a>.</p> <p>They use strategies such as attractive packaging and strategic product placement to influence people’s decisions.</p> <p>New ways of studying how people’s brains process information – right up to the last minute – can help marketers design more effective strategies.</p> <h2>Opportunities for further research</h2> <p>Further research in this area could explore how different types of information, such as environmental cues or memories, affect this continuous decision evaluation process in different groups of people.

Dr Charlie Teo's surprising next move after Aussie surgery restrictions

<p>One year after being slapped with restrictions that effectively stopped him from operating in Australia, Dr Charlie Teo is restarting his career overseas. </p> <p>The neurosurgeon was investigated by Australia’s Health Care Complaints Commission, who last year placed restrictions on the surgeon after they discovered he had been operating on tumours that had been deemed "inoperable". </p> <p>Now, one of China’s most respected neurosurgeons has thanked Australia for imposing such restrictions because it has allowed her country to benefit from the controversial surgeon’s ability to remove high-risk brain tumours.</p> <p>Dr Teo has been operating regularly in China including on high profile VIPs, and at least eight other countries around the world, according to reports from the <em>Sunday Telegraph</em>. </p> <p>An investigation has found Dr Teo has operated on 150 patients, with many of them being from Australia, in China, Spain, Germany, India, Switzerland, Brazil, Peru, South Africa, and Nepal since the restrictions effectively stopped him from operating in Australia.</p> <p>In an interview from Beijing, Professor Ling Feng, Deputy Director of the China International Neuroscience Institute, said she is “not worried” about the restrictions imposed on Dr Teo a year ago for unsatisfactory conduct.</p> <p>“I took a careful look into what happened over there. I don’t think it should be imputed to Charlie’s neglect of care and passion for the patients,” Professor Ling told the <em>Sunday Telegraph</em>.</p> <p>“It is just a different view of the indications for surgery. Similar cases occur across the world. Instead, I ‘thank’ Australia for the restrictions on Charlie, which gave me the opportunity to work with him.”</p> <p>In the past year, patients have travelled from Australia, Romania, Britain, Saudi Arabia, France, Indonesia, and Singapore to have Dr Teo operate.</p> <p>Of those surgeries Dr Teo’s logbook documents one death, one “poor” outcome, three “fair outcomes”, 20 “good outcomes” and 145 cases have been documented as “excellent”.</p> <p>Dr Teo says his results are better than ever and he feels terrible for patients in his own country that he can’t help, but hopes that he may one day be able to return to Australian operating rooms to help patients. </p> <p>“All it would take is one sensible and brave person in one hospital somewhere in Australia to change the status quo,” Dr Teo said.</p> <p>“Just one person to sit back and go ‘okay he might be an a**hole, he might be into money, he might be a bit of a cowboy, he might be all the things the media have said he might be, but the fact is that patients, Australian patients, some need him and he does operations that other people don’t do and most of those outcomes are good so what about we just drop the politics and allow him to operate in Australia?"</p> <p>“That’s all it would take … some common sense for the greater good, not for his sake but for the sake of patients.”</p> <p><em>Image credits: Instagram </em></p>

Grisly find in Sam Armytage's surgery

<p>Samantha Armytage has revealed the grisly find doctors made when she underwent hip replacement <a href="https://www.oversixty.com.au/health/caring/sam-armytage-in-hospital-for-major-surgery" target="_blank" rel="noopener">surgery</a>. </p> <p><em>The Farmer Wants A Wife </em>host, 47, took to Instagram to share a photo of a piece of cartilage surgeons removed from her joint during the surgery. </p> <p>“Do you want to see something disgusting from my recent operation?” she began with a warning to more squeamish followers. </p> <p>“Lol. I knew you’d all look,” she continued.</p> <p>“This is a 3cm chunk of rock-like cartilage that’s been floating around inside my hip joint for decades. As my surgeon said; ‘you must have been in soooooo much pain!’ I was.”</p> <p>The TV star previously said that she had a skiing accident 30 years ago, which took a toll on her right hip. </p> <p>“I’d torn all the cartilage out,” she wrote on Instagram at the time.</p> <p>“It was bone-on-bone and then became full of severe osteoarthritis.”</p> <p>“I’m now truly bionic and my nearest and dearest are pleased to not have to watch me limp around in pain anymore,” Armytage said.</p> <p>“Huge thanks to the wonderful nurses (at St Vincent’s Hospital Sydney) for the care, a lil’ bit of Endone … heaps of rehab and all my beautiful friends for my flower-filled room!”</p> <p><em>Images: Instagram</em></p>
