Do mobile phones cause brain cancer? Science makes definitive call

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. A new comprehensive review commissioned by the World Health Organization has found that mobile phones are NOT linked to brain and head cancers. 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. “We concluded the evidence does not show a link between mobile phones and brain cancer or other head and neck cancers," he said. The review, which was published on Wednesday, focused on cancers of the nervous system, salivary gland and brain tumours. 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. “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. Despite emitting electromagnetic radiation, also known as radio waves, the exposure is relatively low. 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.” 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." “We’re always exposed to low-level radio waves in the everyday environment.” 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. 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. 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. 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”. 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. 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. “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.

Readers response: What would you do if you won $1,000,000 in the lottery tomorrow?

Many people, especially those who indulge in weekly lottery tickets, like to fantasise about what they would do if they came into a huge sum of money. For some people, their first purchase would be a house or a once in a lifetime holiday, while others would give the money to family or charity. We asked our reader what they would do if they won $1 million in the lottery tomorrow, and the response was overwhelming. Here's what they said. Anne Hare - I'd find a really good accountant and put him on retainer. I'd tell no one until I'd got my finances in order. Then I'd go nuts! Irene Winters - Give most of it to our children and grandchildren, and keep a bit to pay for our old age. Erica Whitehead - Help my family and do a kitchen and bathroom renovation. Julie Armstrong - 1 million would be perfect for us to buy a house and live out the rest of ours days comfortably and not have to stress over the rent increases. Plus, we could pay off our daughter's mortgage. Darlene Challen - Fix this house up properly, sell it and find my dream little house for myself and my dog, might spend Christmas in NY and/or go on a tropical cruise, then put the rest away for my 9 grandies. Karen Neilson - Give a big chunk to my children and grandchildren, then give some to each of my siblings and Brother in Law. Keep some for myself, just enough to live comfortably for the few years I’m still on this earth! Give some to Cancer Research, The Heart Foundation and the Rescue Chopper. Give some to a couple of friend who do it tough. Marlene Hassett - Buy a new car and a couple of things around my house and the rest to my kids and grandkids. Alex Elson - I would finally, finally take our van out of the shed and go away for a while! Jeannine Litmanowicz - I would open a scholar fund for my grandchildren so they have money for higher education when they grow up. And also, since they are still young, I would treat them to a week travelling around with them and my daughters and husbands to the Balkans. Christine Whyte - Keep myself very comfortable till it was time to distribute to 10 grandkids. Image credits: Shutterstock

I’m due for a cervical cancer screening. What can I expect? Can I do it myself? And what happened to Pap smears?

<div class="theconversation-article-body"> <a href="https://theconversation.com/profiles/karen-canfell-22668">Karen Canfell</a>, <a href="https://theconversation.com/institutions/university-of-sydney-841">University of Sydney</a>; <a href="https://theconversation.com/profiles/deborah-bateson-16105">Deborah Bateson</a>, <a href="https://theconversation.com/institutions/university-of-sydney-841">University of Sydney</a>, and <a href="https://theconversation.com/profiles/megan-smith-131901">Megan Smith</a>, <a href="https://theconversation.com/institutions/university-of-sydney-841">University of Sydney</a> Cervical screening in Australia has <a href="https://pubmed.ncbi.nlm.nih.gov/34499374/">changed</a> over the past seven years. The test has changed, and women (and people with a cervix) now have much more choice and control. Here’s why – and what you can expect if you’re aged 25 to 74 and are <a href="https://www.health.gov.au/our-work/national-cervical-screening-program">due for a test</a>. <h2>When and why did the test change?</h2> In 2017, Australia became one of the first two countries to transition from Pap smears to tests for the presence of the human papillomavirus (HPV). HPV causes virtually all cervical cancers, so testing for the presence of this virus is a very good indicator of a person’s current and future risk of the disease. This contrasts with the older Pap smear technology, which involved inspection of cells every two years for the changes resulting from HPV infection. The change to screening was supported by a very large body of <a href="https://www.thelancet.com/journals/lancet/article/PIIS0140-6736(13)62218-7/abstract">international</a> and <a href="https://journals.plos.org/plosmedicine/article?id=10.1371/journal.pmed.1002388">Australian</a> data showing primary testing for HPV is more accurate than Pap smears. Women and people with a cervix who do not have HPV detected on their test are at a very low risk of developing cervical cancer over the next five years, or even longer. This was the basis for lengthening the screening interval when HPV screening was introduced. Australia now <a href="https://www.health.gov.au/our-work/national-cervical-screening-program">recommends</a> five-yearly HPV screening, starting at age 25 up to the age of 74 for eligible people, whether or not they have been vaccinated against HPV. Many other countries are following suit to transition to HPV screening. All established screening tests – which are conducted in people without any symptoms – are associated with health benefits but also with some harms. These can include the psychological and clinical consequences of receiving a “positive” screening result, which needs to be investigated further. However, recent World Health Organization (WHO) <a href="https://www.nejm.org/doi/full/10.1056/NEJMsr2030640">reviews of the evidence</a> have found: <ul> <li>HPV is a more effective screening test than Pap smears or any other method</li> <li>it substantially reduces incidence and death rates from cervical cancer</li> <li>it is the method of cervical screening that has the <a href="https://www.nature.com/articles/s41591-023-02600-4">best balance</a> of benefits to harms.</li> </ul> As a consequence, the WHO now unequivocally <a href="https://www.who.int/publications/i/item/9789240030824">recommends</a> HPV screening as the best-practice method. <h2>Now you can collect your own sample</h2> One of the major benefits of switching to HPV screening is it opened the door for a person being able to <a href="https://www.health.gov.au/self-collection-for-the-cervical-screening-test">collect their own sample</a> (which was impossible with the Pap smear). If HPV is present, it can be detected in the vagina rather than having to directly sample the cervix. In 2022, Australia became one of the <a href="https://www.health.gov.au/ministers/the-hon-greg-hunt-mp/media/landmark-changes-improving-access-to-life-saving-cervical-screenings">first countries</a> in the world to introduce a universal option to choose self-collection within a major national-level screening program. This means people eligible for screening, under the guidance of a primary care practitioner, can now choose to collect their own vaginal sample, in privacy, using a simple swab. By the end of 2023, <a href="https://www.ncsr.gov.au/about-us/news-and-media/self-collection-for-cervical-screening--at-an-all-time-high.html">27% of people</a> were choosing to take the test this way, but this is on an upward trajectory and is likely to increase further, with an <a href="https://acpcc.org.au/self-collection-campaign/">awareness campaign</a> due to start next month. <h2>So what happens when I have a test?</h2> You’ll receive an invitation from the <a href="https://www.ncsr.gov.au/information-for-participants/participant-forms-and-guides.html#cervical-forms">National Cancer Screening Register</a> to attend your first screen when you turn 25. If you’re older, you’ll receive reminders when you are due for your next test. You will be invited to visit your GP or community health service for the test. You should be asked whether you would prefer to have a clinician collect the test or whether you would prefer to take the sample yourself. There’s no right or wrong way. The accuracy of testing has been <a href="https://www.bmj.com/content/363/bmj.k4823">shown</a> to be equivalent for clinician or self-collected sampling. This is a matter of choice. If the clinician does the test, they will undertake a pelvic examination with a speculum inserted into the vagina. This enables the doctor or nurse to view the cervix and take a sample. If you are interested in the self-collection option, check whether the practice is offering it when making an appointment. If you opt for self-collection, you’ll be able to do so in private. You’ll be given a swab (which looks like a COVID test swab with a longer stem), and you’ll be given instructions about how to insert and rotate the swab in the vagina to take the sample. It takes only a few minutes. <h2>What does it mean if my test detects HPV?</h2> If your test detects HPV, this means you have an HPV infection. These are very common and by itself doesn’t mean you have cancer, or even pre-cancer (which involves changes to cervical cells that make them more likely to develop into cancer over time). It does mean, however, that you are at higher risk of having a pre-cancer, or developing one in future, and that you will benefit from further follow-up or diagnostic testing. Your doctor or nurse will <a href="https://www.cancer.org.au/clinical-guidelines/cervical-cancer/cervical-cancer-screening">guide you</a> on the next steps in line with national guidelines. If you require a diagnostic examination, this will involve a procedure called colposcopy, where the cervix is closely examined by a gynaecologist or other specially trained healthcare practitioner, and a small sample may be taken for detailed examination of the cells. If you have a pre-cancer, you can be treated simply and quickly, usually without needing to be admitted to hospital. Treatment involves ablating or removing a small area of the cervix. This treatment will drastically reduce your risk of ever developing cervical cancer. <h2>What does this mean for cervical cancer rates?</h2> Cervical screening for HPV is a very effective method of preventing cervical cancer. Because of Australia’s HPV screening, combined with HPV vaccination in younger people, Australia is <a href="https://www.thelancet.com/journals/lanpub/article/PIIS2468-2667(18)30183-X/fulltext">expected</a> to achieve such low rates of cervical cancer by 2035 that it will be considered eliminated. Last year, the government launched a <a href="https://www.health.gov.au/sites/default/files/2023-11/national-strategy-for-the-elimination-of-cervical-cancer-in-australia.pdf">national strategy for cervical cancer elimination</a> which provides key recommendations for eliminating cervical cancer, and for doing so equitably in all groups of women and people with a cervix. One of the best things you can do to protect yourself is to have your cervical screening test when you become eligible, whether or not you have been vaccinated against HPV.

Australia’s gender pay gap has hit a record low – but we still have work to do

<div class="theconversation-article-body"><a href="https://theconversation.com/profiles/leonora-risse-405312">Leonora Risse</a>, <a href="https://theconversation.com/institutions/university-of-canberra-865">University of Canberra</a> Australia’s gender pay gap – a key measure of economic inequality between men and women – has fallen to a record low of 11.5%. That’s down from 13% this time last year, the steepest annual fall since 2016. Ten years ago, it was almost 19%. The latest figures are great news for our economy and our society – evidence we’re getting better at recognising and fairly valuing women’s capabilities and contributions. More opportunities are now open to women in the workforce, helping them gain and retire with greater financial independence than in previous decades. But national averages don’t tell the whole story. While gender pay gaps have fallen in some industries, they’ve also been rising in others. Today, August 19, is <a href="https://www.wgea.gov.au/pay-and-gender/equal-pay-day-2024">equal pay day</a>. This marks the 50 extra days past the end of the last financial year that Australian women would need to work for their earnings to match those of their male colleagues. This offers us a timely opportunity to reflect on what exactly has driven this year’s improvement – and where we still have work to do. <h2>Women’s earnings picking up pace</h2> We calculate the gender pay gap by comparing the average weekly ordinary-time, full-time <a href="https://www.abs.gov.au/statistics/labour/earnings-and-working-conditions/average-weekly-earnings-australia">earnings</a> for men and women. In dollar terms, women are now earning $231.50, or 11.5%, less than men, on average, in their weekly full-time pay packet. <hr /> <iframe id="HwwJ5" class="tc-infographic-datawrapper" style="border: 0;" src="https://datawrapper.dwcdn.net/HwwJ5/1/" width="100%" height="400px" frameborder="0" scrolling="no"></iframe> <hr /> The recent narrowing is being driven by women’s average earnings growth picking up pace. This contrasts with <a href="https://www.abc.net.au/news/2018-10-02/fact-check-gender-pay-gap/10302358">earlier periods</a> in which the narrowing of the gap tended to be due to a slowdown in the growth of men’s earnings. <hr /> <iframe id="R7uFE" class="tc-infographic-datawrapper" style="border: 0;" src="https://datawrapper.dwcdn.net/R7uFE/1/" width="100%" height="400px" frameborder="0" scrolling="no"></iframe> <hr /> <h2>What’s behind the improvement?</h2> While changes in the gender pay gap reflect a range of economy-wide factors, the Albanese government has been quick to attribute the recent fall to the various <a href="https://www.linkedin.com/feed/update/urn:li:activity:7229747376511447040/">targeted actions</a> it has taken since coming to office. Let’s look at whether and how these actions have played a role. First, the government sought to make wage information more transparent. It <a href="https://theconversation.com/pay-secrecy-clauses-are-now-banned-in-australia-heres-how-that-could-benefit-you-195814">banned pay secrecy clauses</a> and now requires the gender pay gaps of all large companies in Australia to be <a href="https://theconversation.com/qantas-pays-women-37-less-telstra-and-bhp-20-fifty-years-after-equal-pay-laws-we-still-have-a-long-way-to-go-223870">publicly reported</a>. These reforms took effect from 2023, targeting private companies. The gender pay gap in the private sector, though higher to begin with, has fallen more swiftly than that of the public sector, suggesting these actions have had an effect. <hr /> <iframe id="ZKMdm" class="tc-infographic-datawrapper" style="border: 0;" src="https://datawrapper.dwcdn.net/ZKMdm/1/" width="100%" height="400px" frameborder="0" scrolling="no"></iframe> <hr /> Second, the government targeted gender-patterned biases in industrial relations – including the <a href="https://theconversation.com/50-years-after-equal-pay-the-legacy-of-womens-work-remains-118761">legacy effects</a> of past decisions – and instilled gender equity as a new objective of Australia’s Fair Work Act. The Fair Work Commission is now required to take gender equity into account in its wage deliberations, including its <a href="https://www.fwc.gov.au/documents/resources/2024fwcfb3500.pdf">minimum wage decision</a>. The government also introduced multi-employer bargaining in an attempt to strengthen workers’ bargaining capacity in female-concentrated sectors. The effects of these changes will continue to flow across the workforce as the Fair Work Commission undertakes its review of modern awards, prioritising those affecting <a href="https://www.fwc.gov.au/hearings-decisions/major-cases/gender-undervaluation-priority-awards-review">female-concentrated industries</a>. <figure class="align-right zoomable"><figcaption></figcaption></figure> And third, further addressing the historical undervaluation of “women’s work”, the government directly addressed low pay in female-concentrated sectors by supporting a pay rise for <a href="https://www.fairwork.gov.au/newsroom/news/15-per-cent-wage-increase-aged-care-sector">aged care workers</a>. Targeting the low pay and under-valuation of an industry that is about 87% female helped fuel the downward momentum in the overall gender pay gap. The government’s recently announced pay rise for <a href="https://ministers.education.gov.au/anthony-albanese/pay-rise-early-educators-while-keeping-fees-down-families">early childhood education and care workers</a> – a workforce that is around 95% female – will also target gender patterns in low pay once they come into effect. These government actions have been essential for undoing the gender biases embedded in existing systems. And they have complemented other initiatives that have taken effect in the past year, such as the <a href="https://www.respectatwork.gov.au/new-positive-duty-employers-prevent-workplace-sexual-harassment-sex-discrimination-and-victimisation">Respect At Work Act</a>, requiring employers to proactively stamp out sexual harassment. But there is still a way to go to keep closing the gender gaps across all parts of the workforce. <h2>Falling in some industries, rising in others</h2> Breaking down the gender pay gap in earnings by sector paints a more varied picture. In industries like construction, public administration and safety, and retail trade, it has fallen notably over the past two years. <hr /> <iframe id="poLND" class="tc-infographic-datawrapper" style="border: 0;" src="https://datawrapper.dwcdn.net/poLND/1/" width="100%" height="400px" frameborder="0" scrolling="no"></iframe> <hr /> But it remains high in industries like healthcare and social assistance, at over 20%, and finance and insurance at 18%. <hr /> <iframe id="6cLnT" class="tc-infographic-datawrapper" style="border: 0;" src="https://datawrapper.dwcdn.net/6cLnT/2/" width="100%" height="400px" frameborder="0" scrolling="no"></iframe> <hr /> In some industries, the gap has actually increased over the past two years. In arts and recreation services, as well as electricity, gas, waste and water services, it’s been continually rising. <hr /> <iframe id="M8fve" class="tc-infographic-datawrapper" style="border: 0;" src="https://datawrapper.dwcdn.net/M8fve/1/" width="100%" height="400px" frameborder="0" scrolling="no"></iframe> <hr /> <h2>That could reflect a bigger shift</h2> It’s important to interpret these figures carefully. In some instances, a widening of the gender pay gap can reflect a positive shift in an industry’s makeup, if it reflects more women joining a male-dominated sector at entry level, and growing a pipeline of senior women for the future. That’s why the Workplace Gender Equality Agency (WGEA) gives organisations a chance to explain these dynamics in their <a href="https://www.wgea.gov.au/about/our-legislation/publishing-employer-gender-pay-gaps">employer statements</a>, which are published on the WGEA website alongside organisations’ gender pay gaps. Over time, the entry of more women at the junior level can flow through to more gender balance as these women progress to senior and decision-making roles. The real test will be to ensure – by fostering more gender equitable, inclusive and respectful work cultures and systems – that they do.<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/236894/count.gif?distributor=republish-lightbox-basic" alt="The Conversation" width="1" height="1" /> <a href="https://theconversation.com/profiles/leonora-risse-405312">Leonora Risse</a>, Associate Professor in Economics, <a href="https://theconversation.com/institutions/university-of-canberra-865">University of Canberra</a> Image credits: Shutterstock This article is republished from <a href="https://theconversation.com">The Conversation</a> under a Creative Commons license.

"What do you say?" TV host's heartbreaking parenting plea

An Aussie TV host has shared a heartfelt plea for advice after revealing that his 12-year-old daughter has been bullied at school. Barry Du Bois, co-host of The Living Room, shared an emotional post on Instagram admitting he is struggling to help Arabella with the bullying issue, and asked other parents for advice. “I just watched my little girl walk out the gate of our home, a place where I know she is safe and feels a sense of security and belonging,” Barry said. “She is heading to a place that doesn’t offer that same security, her school. As a parent, I’m supposed to protect and guide her through difficult times, but this morning, I am lost.” “Yesterday, Arabella came home from school claiming she was sick,” he continued. "This isn’t the first time it has happened. She wasn’t actually sick but is instead being bullied again.” Barry then asked for help from his followers on how to help his daughter, asking, “What do you say to a child when you’ve already said, ‘Don’t let them upset you. Just keep being kind. You are not the horrible things they say’.” “She said, ‘I don’t want to be special; I just want to be liked’,” the TV star added before revealing he felt “weak, angry, confused and a little fearful”. The touching post encouraged some of his famous friends to share their own stories of helping their kids deal with bullying. “My mate sent his daughter to Jiu Jitsu after being bullied. She fell in love with it and gained another level of confidence,” wrote The Bachelor Australia star Tim Robards. “Sometimes you’ve just got to go up to the parents and say, ‘your kid bullies mine’,” added Married At First Sight’s Ryan Gallagher.

I’ve recovered from a cold but I still have a hoarse voice. What should I do?

<div class="theconversation-article-body"><a href="https://theconversation.com/profiles/yeptain-leung-1563747">Yeptain Leung</a>, <a href="https://theconversation.com/institutions/the-university-of-melbourne-722">The University of Melbourne</a> Cold, flu, COVID and <a href="https://theconversation.com/rsv-is-everywhere-right-now-what-parents-need-to-know-about-respiratory-syncytial-virus-208855">RSV</a> have been <a href="https://www.abc.net.au/news/2024-06-21/flu-whooping-cough-rsv-cases-up-as-covid-cases-unkown/104002964">circulating across Australia this winter</a>. Many of us have caught and recovered from <a href="https://theconversation.com/i-feel-sick-how-do-i-know-if-i-have-the-flu-covid-rsv-or-something-else-234266">one of these</a> common upper respiratory tract infections. But for some people their impact is ongoing. Even if your throat isn’t <a href="https://theconversation.com/sore-throats-suck-do-throat-lozenges-help-at-all-184454">sore</a> anymore, your voice may still be hoarse or croaky. So what happens to the voice when we get a virus? And what happens after? Here’s what you should know if your voice is still hoarse for days – or even weeks – after your other symptoms have resolved. <h2>Why does my voice get croaky during a cold?</h2> A healthy voice is normally clear and strong. It’s powered by the lungs, which push air past the vocal cords to make them vibrate. These vibrations are amplified in the throat and mouth, creating the voice we hear. The vocal cords are two elastic muscles situated in your throat, around the level of your laryngeal prominence, or Adam’s apple. (Although everyone has one, it tends to be more pronounced in males.) The vocal cords are small and delicate – around the size of your fingernail. Any small change in their structure will affect how the voice sounds. When the vocal cords become inflamed – known as laryngitis – your voice will sound different. Laryngitis is a common part of upper respiratory tract infections, but can also be caused through misuse. <figure class="align-center "><img src="https://images.theconversation.com/files/614706/original/file-20240821-17-nzg1mc.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/614706/original/file-20240821-17-nzg1mc.jpg?ixlib=rb-4.1.0&q=45&auto=format&w=600&h=366&fit=crop&dpr=1 600w, https://images.theconversation.com/files/614706/original/file-20240821-17-nzg1mc.jpg?ixlib=rb-4.1.0&q=30&auto=format&w=600&h=366&fit=crop&dpr=2 1200w, https://images.theconversation.com/files/614706/original/file-20240821-17-nzg1mc.jpg?ixlib=rb-4.1.0&q=15&auto=format&w=600&h=366&fit=crop&dpr=3 1800w, https://images.theconversation.com/files/614706/original/file-20240821-17-nzg1mc.jpg?ixlib=rb-4.1.0&q=45&auto=format&w=754&h=460&fit=crop&dpr=1 754w, https://images.theconversation.com/files/614706/original/file-20240821-17-nzg1mc.jpg?ixlib=rb-4.1.0&q=30&auto=format&w=754&h=460&fit=crop&dpr=2 1508w, https://images.theconversation.com/files/614706/original/file-20240821-17-nzg1mc.jpg?ixlib=rb-4.1.0&q=15&auto=format&w=754&h=460&fit=crop&dpr=3 2262w" alt="Two drawn circles comparing normal vocal cords with inflamed, red vocal cords." /><figcaption>Viruses such as the common cold can inflame the vocal cords. <a class="source" href="https://www.shutterstock.com/image-vector/dry-sore-loss-cough-virus-viral-1821458117">Pepermpron/Shutterstock</a></figcaption></figure> Catching a virus triggers the body’s defence mechanisms. White blood cells are recruited to kill the virus and heal the tissues in the vocal cords. They become inflamed, but also stiffer. It’s harder for them to vibrate, so the voice comes out hoarse and croaky. In some instances, you may find it hard to speak in a loud voice or have a reduced pitch range, meaning you can’t go as high or loud as normal. You may even “lose” your voice altogether. Coughing can also make things worse. It is the body’s way of trying to clear the airways of irritation, including your own mucus dripping onto your throat (<a href="https://www.health.harvard.edu/staying-healthy/treatments-for-post-nasal-drip">post-nasal drip</a>). But coughing slams the vocal cords together with force. Chronic coughing can lead to persistent inflammation and even thicken the vocal cords. This thickening is the body trying to protect itself, similar to developing a callus when a pair of new shoes rubs. Thickening on your vocal cords can lead to physical changes in the vocal cords – such as developing a growth or “nodule” – and further deterioration of your voice quality. <figure class="align-center "><img src="https://images.theconversation.com/files/614707/original/file-20240821-21-vizs73.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/614707/original/file-20240821-21-vizs73.jpg?ixlib=rb-4.1.0&q=45&auto=format&w=600&h=376&fit=crop&dpr=1 600w, https://images.theconversation.com/files/614707/original/file-20240821-21-vizs73.jpg?ixlib=rb-4.1.0&q=30&auto=format&w=600&h=376&fit=crop&dpr=2 1200w, https://images.theconversation.com/files/614707/original/file-20240821-21-vizs73.jpg?ixlib=rb-4.1.0&q=15&auto=format&w=600&h=376&fit=crop&dpr=3 1800w, https://images.theconversation.com/files/614707/original/file-20240821-21-vizs73.jpg?ixlib=rb-4.1.0&q=45&auto=format&w=754&h=473&fit=crop&dpr=1 754w, https://images.theconversation.com/files/614707/original/file-20240821-21-vizs73.jpg?ixlib=rb-4.1.0&q=30&auto=format&w=754&h=473&fit=crop&dpr=2 1508w, https://images.theconversation.com/files/614707/original/file-20240821-21-vizs73.jpg?ixlib=rb-4.1.0&q=15&auto=format&w=754&h=473&fit=crop&dpr=3 2262w" alt="Diagram compares healthy vocal cords with cords that have nodules, two small bumps." /><figcaption>Coughing and exertion can cause inflamed vocal cords to thicken and develop nodules. <a class="source" href="https://www.shutterstock.com/image-vector/dry-sore-loss-cough-virus-viral-1821458126">Pepermpron/Shutterstock</a></figcaption></figure> <h2>How can you care for your voice during infection?</h2> People who use their voices a lot professionally – such as teachers, call centre workers and singers – are often desperate to resume their vocal activities. They are <a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC7478078/">more at risk</a> of forcing their voice before it’s ready. The good news is most viral infections resolve themselves. Your voice is usually restored within five to ten days of recovering from a cold. Occasionally, your pharmacist or doctor may prescribe cough suppressants to limit additional damage to the vocal cords (among other reasons) or mucolytics, which break down mucus. But the most effective treatments for viral upper respiratory tract infections are hydration and rest. Drink plenty of water, avoid alcohol and exposure to cigarette smoke. <a href="https://www.healthdirect.gov.au/laryngitis#:%7E:text=You%20can%20help%20your%20voice%20recover%20by%3A%201,avoid%20nasal%20decongestants%20%28these%20make%20your%20throat%20drier%29">Inhaling steam</a> by making yourself a cup of hot water will also help clear blocked noses and hydrate your vocal cords. Rest your voice by talking as little as possible. If you do need to talk, don’t whisper – this <a href="https://www.sciencedirect.com/science/article/abs/pii/S0892199704001730">strains the muscles</a>. Instead, consider using “<a href="https://www.instagram.com/reel/C0d-oNIMM1y/">confidential voice</a>”. This is a soft voice – not a whisper – that gently vibrates your vocal cords but puts less strain on your voice than normal speech. Think of the voice you use when communicating with someone close by. During the first five to ten days of your infection, it is important not to push through. Exerting the voice by talking a lot or loudly will only exacerbate the situation. Once you’ve recovered from your cold, you can speak as you would normally. <h2>What should you do if your voice is still hoarse after recovery?</h2> If your voice hasn’t returned to normal after <a href="https://www.healthdirect.gov.au/laryngitis">two to three weeks</a>, you should seek medical attention from your doctor, who may refer you to an ear nose and throat specialist. If you’ve developed a nodule, the specialist would likely refer you to a speech pathologist who will show you how to take care of your voice. Many nodules can be <a href="https://britishvoiceassociation.org.uk/voicecare_vocal-nodules.htm">treated</a> with voice therapy and don’t require surgery. You may have also developed a habit of straining your vocal cords, if you forced yourself to speak or sing while they were inflamed. This can be a reason why some people continue to have a hoarse voice even when they’ve recovered from the cold. In those cases, a speech pathologist may play a valuable role. They may teach you to exercises that make voicing more efficient. For example, <a href="https://www.youtube.com/watch?v=fwNPp-RS4IY">lip trills</a> (blowing raspberries) are a fun and easy way you can learn to relax the voice. This can help break the habit of straining your voice you may have developed during infection.<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/236398/count.gif?distributor=republish-lightbox-basic" alt="The Conversation" width="1" height="1" /> <a href="https://theconversation.com/profiles/yeptain-leung-1563747">Yeptain Leung</a>, Postdoctoral Research and Lecturer of Speech Pathology, School of Health Sciences, <a href="https://theconversation.com/institutions/the-university-of-melbourne-722">The University of Melbourne</a> This article is republished from <a href="https://theconversation.com">The Conversation</a> under a Creative Commons license.

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

<div class="theconversation-article-body"><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. Ferreira</a>, <a href="https://theconversation.com/institutions/university-of-sydney-841">University of Sydney</a>; <a href="https://theconversation.com/profiles/joshua-zadro-504754">Joshua Zadro</a>, <a href="https://theconversation.com/institutions/university-of-sydney-841">University of Sydney</a>, and <a href="https://theconversation.com/profiles/rana-hinman-1536232">Rana Hinman</a>, <a href="https://theconversation.com/institutions/the-university-of-melbourne-722">The University of Melbourne</a> Most people with knee osteoarthritis can control their pain and improve their mobility without surgery, according to <a href="https://www.safetyandquality.gov.au/standards/clinical-care-standards/osteoarthritis-knee-clinical-care-standard">updated treatment guidelines</a> from the Australian Commission on Safety and Quality in Health Care. So what is knee osteoarthritis and what are the best ways to manage it? <h2>More than 2 million Australians have osteoarthritis</h2> Osteoarthritis is the most common joint disease, affecting <a href="https://www.aihw.gov.au/reports/chronic-musculoskeletal-conditions/osteoarthritis">2.1 million Australians</a>. It <a href="https://www.aihw.gov.au/reports/chronic-musculoskeletal-conditions/osteoarthritis">costs the economy</a> A$4.3 billion each year. 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. Most people with osteoarthritis have persistent pain and find it difficult to perform simple daily tasks, such as walking and climbing stairs. <h2>Is it caused by ‘wear and tear’?</h2> 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”. <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. 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. 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. <h2>What’s the best way to manage osteoarthritis?</h2> 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. 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. 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. 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. 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. Increasing general physical activity is also important, such as taking more steps throughout the day and reducing sedentary time. 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>. 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. Opioids are <a href="https://pubmed.ncbi.nlm.nih.gov/35137418/">not recommended</a>. The risk of harm outweighs any potential benefits. <h2>What about surgery?</h2> People with knee osteoarthritis commonly undergo two types of surgery: knee arthroscopy and knee replacement. 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. 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. 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. 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. 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. <h2>I have knee osteoarthritis. What should I do?</h2> The <a href="https://www.safetyandquality.gov.au/standards/clinical-care-standards/osteoarthritis-knee-clinical-care-standard">care standard</a> links to free evidence-based resources to support people with osteoarthritis.

Boeing Starliner astronauts: what six months stuck in space may do to their perception of time

<div class="theconversation-article-body"><a href="https://theconversation.com/profiles/ruth-ogden-1182467">Ruth Ogden</a>, <a href="https://theconversation.com/institutions/liverpool-john-moores-university-1319">Liverpool John Moores University</a> and <a href="https://theconversation.com/profiles/daniel-eduardo-vigo-1631723">Daniel Eduardo Vigo</a>, <a href="https://theconversation.com/institutions/pontificia-universidad-catolica-de-argentina-5531">Pontificia Universidad Católica de Argentina</a> Two astronauts marooned in space may sound like the plot of a Hollywood blockbuster, but for two <a href="https://www.nasa.gov/">Nasa</a> crew members, it is now a reality. Commander Barry Wilmore and pilot Sunita Williams are currently in limbo on the International Space Station (ISS). They arrived in the Boeing Starliner spacecraft – the first test of the spaceship with astronauts. Wilmore and Williams were supposed to stay on the ISS for around eight days and return on the same spacecraft. But there is now debate about the safety of Starliner after it experienced <a href="https://www.bbc.co.uk/news/articles/c6pp29gdwe6o">helium leaks and thruster problems</a> on its way to the ISS. In coming days, Nasa and Boeing may decide to clear Starliner to carry the astronauts back to Earth. This means their stay might not last too much longer. But if officials decide against Starliner, the astronauts face waiting an <a href="https://www.nasa.gov/news-release/update-nasa-boeing-to-stream-flight-test-mission-briefing-on-nasa/">additional six months in orbit</a> before returning. So how do astronauts cope with a potential six-month wait for a lift home? <a href="https://www.sciencedirect.com/science/article/abs/pii/0022249685900203">Waiting for things is difficult</a> at the best of times. Under normal circumstances, it is <a href="https://journals.sagepub.com/doi/full/10.1177/2043808718778982">frustrating, stressful and anxiety-provoking</a>. But in extreme situations, with high stakes, <a href="https://onlinelibrary.wiley.com/doi/full/10.1111/j.1365-2648.2011.05638.x?casa_token=jC_hT4wqbuIAAAAA%3AGTrJPmd496aDTdirdwYi7CvLK8Q1g_oR-Em2E3EpDP0AwRCs2ko13Jpqui15BlkPiAx7MMRqA0MC">waiting can be purgatory</a>. Part of the reason that waiting is difficult is that it distorts our sense of time. Think of last time you were waiting for a delayed train, test results or a text from a potential new partner. Did it fly by or drag? For most people, time spent waiting crawls at a glacial pace. As a result, delays and periods of anticipation often feel much longer than they actually are. Waiting slows our perception of time, because it changes the amount of time that we spend <a href="https://www.jstor.org/stable/23324610?casa_token=KmtJWWmtHwQAAAAA%3AN_CUdtNakK46j4ItZaH_f__QcIGOjMnasX1NeMTRFH5YPpcmYx1JpigTfTb1bPYi5Fcus-IhtzDX0Jsz3xpqZRMDUxg0RWYhSr87V-zXz_pqS0zM&seq=2">thinking about time</a>. During normal daily life we often ignore time; our brains have a limited capacity. If time isn’t important, we simply don’t think about it, and this helps it to pass quickly. When we are waiting, our desire to know when the wait is over increases how much we think about time. This “clock watching” can make the minutes and hours feel like they are <a href="https://doi.org/10.1016/0278-2626(90)90026-K">passing at a snail’s pace</a>. Stress, discomfort and pain exacerbate this effect, meaning that waiting in difficult situations <a href="https://doi.org/10.1002/ejp.2211">can seem even longer</a>. Waiting also slows our perception of time because it what we do and how we feel. Normal life is busy and full of ever-changing activities and interactions. The sudden need to wait halts the flow of life, often leaving us with nothing else to do, thus increasing levels of boredom and frustration. In general, time filled with activity <a href="https://doi.org/10.1016/0278-2626(90)90026-K">passes more quickly</a>. We all got a taste of this during <a href="https://doi.org/10.1371/journal.pone.0235871">COVID lockdowns</a>. When we were stuck inside unable to see friends and engage in normal daily activities, the loss of routine and distractions caused time to drag for many. For the astronauts stuck on the ISS, anxiety about when they will return, limited opportunities for activities and fewer opportunities to contact friends and families combine to make their wait to return home feel significantly longer than six months – if it should come to that. However, as academics who research the effects of time on human psychology and biology, our ongoing work with crew members at research stations in Antarctica aims to shed light on whether waiting in extreme environments is different to waiting during normal daily life. <h2>A year in Antarctica</h2> While being stuck for six months on the ISS may sound like many people’s worst nightmare, it is not uncommon for scientists to spend long periods isolated and confined in extreme environments. Every year, organisations such as the Instituto Antártico Argentino (which uses the Belgrano II Antarctic station), the French Polar Institute and the Italian Antarctic Programme, in cooperation with the European Space Agency (which all use Antarctica’s Concordia station), send crews of people for up to 16 months to conduct research on the frozen continent. During the March to October <a href="https://www.bas.ac.uk/">polar winter</a>, teams spend six months in near darkness – and from May to August, in complete darkness – facing outside temperatures of up to -60C, wind speeds of 160 km/h (100 mph) and storms which prevent almost all outdoor activity. Limited internet coverage can also prevent constant communication with the outside world. For the last year, we have researched how life in Antarctica influences people’s experience of time. Each month, we asked crew members how time felt like it was passing in comparison to before their mission. Trapped on base, with limited contact with the outside world, you might expect time to drag. However, our results suggest the opposite may be true. Analysis of crew members’ experiences indicated that being constantly busy with complex tasks such as scientific research helped time to pass swiftly, according to 80% of crew responses. Only 3% of responses indicated that time actually dragged, and these reports occurred when nights were long and there was little to do. These experiences may provide hope for those stuck on the ISS. Like life on an Antarctic station, these Nasa astronauts have a busy and mentally demanding existence. These factors may help time to pass quickly. However, a key factor of their wait may be their ability to <a href="https://journals.sagepub.com/doi/10.1177/2043808718778982">tolerate the uncertainty</a> of when they will return.

No, your aches and pains don’t get worse in the cold. So why do we think they do?

<div class="theconversation-article-body"> <a href="https://theconversation.com/profiles/manuela-ferreira-161420">Manuela Ferreira</a>, <a href="https://theconversation.com/institutions/george-institute-for-global-health-874">George Institute for Global Health</a> and <a href="https://theconversation.com/profiles/leticia-deveza-1550633">Leticia Deveza</a>, <a href="https://theconversation.com/institutions/university-of-sydney-841">University of Sydney</a> It’s cold and wet outside. As you get out of bed, you can feel it in your bones. Your right knee is flaring up again. That’ll make it harder for you to walk the dog or go to the gym. You think it must be because of the weather. It’s a common idea, but a myth. When we looked at the evidence, <a href="https://www.sciencedirect.com/science/article/pii/S0049017224000337">we found</a> no direct link between most common aches and pains and the weather. In the first study of its kind, we found no direct link between the temperature or humidity with most joint or muscle aches and pains. So why are so many of us convinced the weather’s to blame? Here’s what we think is really going on. <h2>Weather can be linked to your health</h2> The weather is often associated with the risk of new and ongoing health conditions. For example, cold temperatures <a href="https://pubmed.ncbi.nlm.nih.gov/27021573/">may worsen</a> asthma symptoms. Hot temperatures <a href="https://www.thelancet.com/journals/lanplh/article/PIIS2542-5196(22)00117-6/fulltext">increase the risk</a> of heart problems, such as arrhythmia (irregular heartbeat), cardiac arrest and coronary heart disease. Many people are also convinced the weather is linked to their aches and pains. For example, <a href="https://onlinelibrary.wiley.com/doi/abs/10.1111/j.1479-8077.2004.00099.x?casa_token=jvpSbA4szqoAAAAA%3ATyHyGaqXmfevWyuJe6LW_3Pap3IPHC8HSMTl3RN63mFzNO0X7ozQjBb6Bi3yVFuPjqkrf-WlB-J5A1q1">two in every three</a> people with knee, hip or hand osteoarthritis <a href="https://bmcmusculoskeletdisord.biomedcentral.com/articles/10.1186/1471-2474-15-66">say</a> cold temperatures trigger their symptoms. Musculoskeletal conditions affect more than <a href="https://www.aihw.gov.au/reports/chronic-musculoskeletal-conditions/musculoskeletal-conditions-comorbidity-australia/summary">seven million Australians</a>. So we set out to find out whether weather is really the culprit behind winter flare-ups. <h2>What we did</h2> Very few studies have been specifically and appropriately designed to look for any direct link between weather changes and joint or muscle pain. And ours is the first to evaluate data from these particular studies. We looked at data from more than 15,000 people from around the world. Together, these people reported more than 28,000 episodes of pain, mostly back pain, knee or hip osteoarthritis. People with rheumatoid arthritis and gout were also included. We then compared the frequency of those pain reports between different types of weather: hot or cold, humid or dry, rainy, windy, as well as some combinations (for example, hot and humid versus cold and dry). <h2>What we found</h2> We found changes in air temperature, humidity, air pressure and rainfall do not increase the risk of knee, hip or lower back pain symptoms and are not associated with people seeking care for a new episode of arthritis. The results of this study suggest we do not experience joint or muscle pain flare-ups as a result of changes in the weather, and a cold day will not increase our risk of having knee or back pain. In order words, there is no direct link between the weather and back, knee or hip pain, nor will it give you arthritis. It is important to note, though, that very cold air temperatures (under 10°C) were rarely studied so we cannot make conclusions about worsening symptoms in more extreme changes in the weather. The only exception to our findings was for gout, an inflammatory type of arthritis that can come and go. Here, pain increased in warmer, dry conditions. Gout has a very different underlying biological mechanism to back pain or knee and hip osteoarthritis, which may explain our results. The combination of warm and dry weather may lead to increased dehydration and consequently increased concentration of uric acid in the blood, and deposition of uric acid crystals in the joint in people with gout, resulting in a flare-up. <h2>Why do people blame the weather?</h2> The weather can influence other factors and behaviours that consequently shape how we perceive and manage pain. For example, some people may change their physical activity routine during winter, choosing the couch over the gym. And we know <a href="https://pubmed.ncbi.nlm.nih.gov/28700451/">prolonged sitting</a>, for instance, is directly linked to worse back pain. Others may change their sleep routine or sleep less well when it is either too cold or too warm. Once again, a bad night’s sleep can trigger your <a href="https://link.springer.com/article/10.1007/s00586-021-06730-6">back</a> and <a href="https://www.sciencedirect.com/science/article/pii/S1063458421007020">knee</a> pain. Likewise, changes in mood, often experienced in cold weather, trigger increases in both <a href="https://link.springer.com/article/10.1007/s00586-021-06730-6">back</a> and <a href="https://www.sciencedirect.com/science/article/pii/S1063458421007020">knee</a> pain. So these changes in behaviour over winter may contribute to more aches and pains, and not the weather itself. Believing our pain will feel worse in winter (even if this is not the case) may also make us feel worse in winter. This is known as the <a href="https://link.springer.com/article/10.1186/s12891-018-1943-8">nocebo effect</a>. <h2>What to do about winter aches and pains?</h2> It’s best to focus on risk factors for pain you can control and modify, rather than ones you can’t (such as the weather). You can: <ul> <li> become more physically active. This winter, and throughout the year, aim to walk more, or talk to your health-care provider about gentle exercises you can safely do at home, with a physiotherapist, personal trainer or at the pool </li> <li> lose weight if obese or overweight, as this is linked to <a href="https://jamanetwork.com/journals/jama/article-abstract/2799405">lower levels</a> of joint pain and better physical function </li> <li> keep your body warm in winter if you feel some muscle tension in uncomfortably cold conditions. Also ensure your bedroom is nice and warm as we tend to sleep <a href="https://www.sciencedirect.com/science/article/pii/S0033350623003359">less well</a> in cold rooms </li> <li> maintain a healthy diet and <a href="https://www.thelancet.com/journals/lanrhe/article/PIIS2665-9913(23)00098-X/fulltext">avoid smoking</a> or drinking high levels of alcohol. These are among <a href="https://ard.bmj.com/content/annrheumdis/82/1/48.full.pdf">key lifestyle recommendations</a> to better manage many types of arthritis and musculoskeletal conditions. For people with back pain, for example, a healthy lifestyle is linked with <a href="https://pubmed.ncbi.nlm.nih.gov/36208321/">higher levels</a> of physical function.<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/235117/count.gif?distributor=republish-lightbox-basic" alt="The Conversation" width="1" height="1" /> </li> </ul> <a href="https://theconversation.com/profiles/manuela-ferreira-161420">Manuela Ferreira</a>, Professor of Musculoskeletal Health, Head of Musculoskeletal Program, <a href="https://theconversation.com/institutions/george-institute-for-global-health-874">George Institute for Global Health</a> and <a href="https://theconversation.com/profiles/leticia-deveza-1550633">Leticia Deveza</a>, Rheumatologist and Research Fellow, <a href="https://theconversation.com/institutions/university-of-sydney-841">University of Sydney</a> Image credits: Shutterstock This article is republished from <a href="https://theconversation.com">The Conversation</a> under a Creative Commons license.

It’s hard to reach out to old friends, but doing so may help alleviate loneliness

<div class="theconversation-article-body"> <a href="https://theconversation.com/profiles/lara-b-aknin-1365501">Lara B Aknin</a>, <a href="https://theconversation.com/institutions/simon-fraser-university-1282">Simon Fraser University</a>; <a href="https://theconversation.com/profiles/gillian-sandstrom-1283157">Gillian Sandstrom</a>, <a href="https://theconversation.com/institutions/university-of-sussex-1218">University of Sussex</a>, and <a href="https://theconversation.com/profiles/kristina-castaneto-1548733">Kristina Castaneto</a>, <a href="https://theconversation.com/institutions/simon-fraser-university-1282">Simon Fraser University</a> Millions of <a href="https://www150.statcan.gc.ca/t1/tbl1/en/tv.action?pid=4510004801">Canadians are lonely</a>. This is worrisome because loneliness, defined by the World Health Organization as “<a href="https://www.who.int/news/item/15-11-2023-who-launches-commission-to-foster-social-connection">the social pain of not feeling connected</a>,” predicts both lower mental and physical health. Research shows that lacking a sense of social connection can pose an <a href="https://doi.org/10.1177/1745691614568352">equivalent health risk to smoking 15 cigarettes per day</a>. To combat loneliness, people are commonly advised to seek out social connection. For many, this guidance brings to mind spending time with loved ones, such as close friends, family and romantic partners. But are there other people we can reach out to? In our research, recently published in Communications Psychology, we examined whether people have “old friends” — individuals that they care about but with whom they have lost touch — and <a href="https://doi.org/10.1038/s44271-024-00075-8">how easily these relationships can be rekindled</a>. We found that certain strategies can help people reconnect — and, in new research, we are getting a sense that certain values and personality traits may make it easier for people to stay in touch far into the future. <h2>Reconnecting with old friends</h2> Across a series of seven studies, we found the majority of people reported having an old friend. Yet, when we asked over 400 participants how willing they would be to reach out to an old friend right now, most said they were neutral or unwilling. In fact, in one study, people reported being no more willing to reach out to an old friend than they were to talk to a stranger or pick up trash. This reluctance was observable in behaviour too. We conducted two experiments in which more than 1,000 people were given several minutes to draft and send a message to an old friend. Only 30 per cent sent the message to their old friend. Given that reaching out to an old friend could boost <a href="https://www.forbes.com/sites/nextavenue/2018/08/19/the-power-and-joy-of-reconnecting-with-old-friends/">feelings of social connection and happiness</a>, we tried designing interventions to encourage reaching out. For instance, we reminded participants that reaching out to an old friend was an act of kindness and that the recipient would appreciate it more than they realize. We also tried telling participants not to overthink it — to just send their message. Unfortunately, neither prompt was effective at encouraging more people to reach out. <h2>Reluctance to reconnect</h2> Why are people reluctant to reach out to old friends? There may be a number of reasons, including the possibility that old friends feel like strangers after time has passed. In one study with over 500 participants we asked people to list between three to five old friends, and tell us how close each one felt to them right now. The more unfamiliar an old friend felt, the less willing people were to reach out. Research has found that when people <a href="https://doi.org/10.1016/j.jesp.2022.104356">practise talking to strangers for a week</a>, they become less anxious about it. If old friends can feel like strangers, might a similar strategy encourage people to reach out to old friends? To find out, we conducted an experiment in which we randomly assigned some people to complete a three-minute warm-up activity in which they messaged current family or friends. Other participants were randomly assigned to a control condition in which they simply browsed social media for three minutes instead. Afterward, all participants were given an opportunity to write and send a message to an old friend. While only 30 per cent of participants sent their message in the control condition, over 50 per cent did so after warming-up, suggesting that practising the behaviour that underlies reaching out may make this act easier. <h2>Personality traits</h2> We are extending this research in a number of new directions. For instance, in some newly conducted and unpublished research, we are examining whether people with certain personality traits or beliefs are more likely to send a message to an old friend. Responses from over 300 people suggest that people who are open to new experiences — <a href="https://www.psychologytoday.com/ca/basics/big-5-personality-traits">one of the five key personality traits studied by psychologists</a> — say they are willing to reach out to an old friend. Despite this inclination, our research found that highly open people do not necessarily communicate with old friends when given the chance. On the other hand, people’s values and beliefs may be important determinants of whether they stay in touch. Our preliminary work shows that people who see friendship as a bond that does not easily break may be more likely to reach out than others. We hope this work helps normalize the fact that friendships can fade and be hard to rekindle. That said, with some practice, people can overcome this reluctance and hit “send” to potentially open a path to connection and less loneliness.<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/234895/count.gif?distributor=republish-lightbox-basic" alt="The Conversation" width="1" height="1" /> <a href="https://theconversation.com/profiles/lara-b-aknin-1365501">Lara B Aknin</a>, Distinguished Professor of Social Psychology, <a href="https://theconversation.com/institutions/simon-fraser-university-1282">Simon Fraser University</a>; <a href="https://theconversation.com/profiles/gillian-sandstrom-1283157">Gillian Sandstrom</a>, Senior Lecturer, School of Psychology, <a href="https://theconversation.com/institutions/university-of-sussex-1218">University of Sussex</a>, and <a href="https://theconversation.com/profiles/kristina-castaneto-1548733">Kristina Castaneto</a>, Master's Student, Psychology, <a href="https://theconversation.com/institutions/simon-fraser-university-1282">Simon Fraser University</a> Image credits: Shutterstock This article is republished from <a href="https://theconversation.com">The Conversation</a> under a Creative Commons license.

Relationships

From maxing out to slowing down, how much do heart rates vary across sports?

<div class="theconversation-article-body"><a href="https://theconversation.com/profiles/theresa-larkin-952095">Theresa Larkin</a>, <a href="https://theconversation.com/institutions/university-of-wollongong-711">University of Wollongong</a> and <a href="https://theconversation.com/profiles/gregory-peoples-1556509">Gregory Peoples</a>, <a href="https://theconversation.com/institutions/university-of-wollongong-711">University of Wollongong</a> A classic image of the Olympics and Paralympics is an athlete at the end of a race struggling for breath, their heart obviously racing. But at the other end of the scale are athletes such as archers and shooters, who need to slow their heart rates down as much as possible. Athletes in speed and endurance events regularly push their heart rate to the maximum. But these athletes usually have low heart rates at rest. What causes our heart rates and respiratory (breathing) rates to change so much, and is this healthy? <h2>When heart rates and respiratory rates rise</h2> If you are still and calm as you read this, your heart is probably beating 60–100 times per minute and you are likely breathing 12–20 times per minute. These are the <a href="https://theconversation.com/what-should-my-heart-rate-be-and-what-affects-it-98945">normal ranges for a resting adult</a>. During physical activity when muscles are contracting, the muscles need more oxygen to provide them with energy to work. To deliver this extra oxygen (<a href="https://theconversation.com/curious-kids-why-is-blood-red-229121#:%7E:text=Haemoglobin%20is%20like%20a%20red,oxygen%2C%20our%20blood%20is%20red.">carried in our blood</a>), our heart pumps blood faster. In other words, our heart rate increases. We also breathe faster to get more oxygen into our lungs to be delivered to the exercising muscles. <figure><iframe src="https://www.youtube.com/embed/3YOap5k0R_8?wmode=transparent&start=0" width="440" height="260" frameborder="0" allowfullscreen="allowfullscreen"></iframe><figcaption>Your resting heart rate can tell you plenty about your health and fitness.</figcaption></figure> <h2>How fast can our heart rate get during exercise?</h2> Aerobic means “with oxygen”. In <a href="https://my.clevelandclinic.org/health/articles/7050-aerobic-exercise">aerobic exercise</a> (“cardio”) you use large muscles repetitively and rhythmically. For example, walking, running, cycling, swimming and rowing. Muscles that are contracting during aerobic exercise use a lot of energy and need ten times <a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC4551211/">more oxygen than at rest</a>. High intensity aerobic events that involve large muscles or the entire body cause the highest heart rates. An <a href="https://www.heartonline.org.au/resources/calculators/target-heart-rate-calculator">estimate</a> of maximum heart rate (beats per minute) is 220 minus your age. This equates to 195 beats per minute for a 25-year-old – close to the average age of the Australian Olympic team of 26.5 years. Athletes competing in Olympic events of endurance or speed will reach their maximum heart rate. You can usually only maintain maximum heart rate for a few minutes. But in a 2000-metre rowing race, the rowers maintain intense effort at close to maximum heart rate for 6–8 minutes. This is one of the toughest events for the heart. It’s no wonder rowers often collapse in the boat <a href="https://www.bbc.com/news/uk-england-cambridgeshire-68731840">as they cross the finish line</a>. Highly trained endurance athletes can have a maximum heart rate higher than expected for their age. <a href="https://olympics.com/en/athletes/eliud-kipchoge">Eliud Kipchoge</a> from Kenya is considered the greatest marathon runner of all time. During his <a href="https://au.coros.com/stories?world-record">world record run</a> in the 2022 Berlin marathon, he ran with a heart rate of around 180 beats per minute for almost the entire race. <h2>How does breathing change with exercise?</h2> Our breathing changes with exercise to increase oxygen uptake from the air. At low-to-moderate intensity exercise, you start to take deeper breaths. This brings in more air and oxygen with each breath. However, there is a limit to how much the chest can expand. With higher intensity exercise, respiratory rate increases to increase oxygen intake. Elite athletes can breathe <a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC4818249/">more than 50 times</a> per minute. This is driven by <a href="https://theconversation.com/what-is-breathwork-and-do-i-need-to-do-it-231192">our diaphragm</a>, the most important muscle of breathing. <a href="https://www.abc.net.au/news/2024-07-28/paris-olympics-grace-brown-cycling-gold-medal-australia/104151466">Grace Brown</a>, Olympic gold medal cyclist in Paris, <a href="https://inscyd.com/article/grace-brown-olympic-gold-physiology/">breathes close to a maximal oxygen uptake</a> when she is cycling at high intensity. <h2>Some athletes need to slow things down</h2> Archery and shooting athletes perform better with a lower heart rate. They time their shots to be <a href="https://pubmed.ncbi.nlm.nih.gov/3580727/#:%7E:text=Results%20showed%20that%20the%20champion,both%20during%20diastole%20and%20systole">between heart beats</a> when the body is the most still. This is easier with a slower heart rate, with more time between beats. Archers consciously lower their heart rate <a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC6441821/">prior to shooting</a> by <a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC6721071/">slowing their breathing</a>. Other Olympians use <a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC10224217/#:%7E:text=For%20practicing%20slow%20and%20deep,minutes%20before%20starting%20the%20exercise.">breathing techniques</a> to calm pre-race anticipation and high heart rates. Slowing the breath, <a href="https://theconversation.com/what-is-breathwork-and-do-i-need-to-do-it-231192">especially the exhale</a>, is the best way to lower your heart rate. Beta-blockers also reduce heart rate, by blocking adrenaline. This is why they are on the <a href="https://www.wada-ama.org/en/prohibited-list">prohibited substances list</a> of the World Anti-Doping Agency. <h2>What about resting heart rates?</h2> Athletes often have a <a href="https://www.health.harvard.edu/heart-health/is-a-low-heart-rate-worrisome">low resting heart rate</a>, around 40-50 beats per minute, and slower during sleep. Some are even lower – five time Tour de France winner Miguel Indurain famously had a resting heart rate of <a href="https://www.cyclingweekly.com/fitness/miguel-indurain-vs-your-body-34288">28 beats per minute</a>. Legendary US swimmer Michael Phelps is the <a href="https://olympics.com/en/news/michael-phelps-olympic-medals-record-how-many-gold-swimmer-world-record">most successful Olympian</a> of all time – he had a resting heart rate of <a href="https://www.reanfoundation.org/low-resting-heart-rate-and-lifespan/#:%7E:text=Studies%20on%20Athletes%20and%20Low%20Resting%20Heart%20Rate&text=It%20could%20also%20hint%20at,BPM%20throughout%20his%20professional%20career">less than 40 beats per minute</a>. Regular moderate-to-vigorous intensity aerobic exercise makes the <a href="https://www.medicalnewstoday.com/articles/athletes-heart-rate">heart stronger and more efficient</a>. A stronger heart pumps more blood per beat, which means it doesn’t need to beat as often. Exercise also <a href="https://pubmed.ncbi.nlm.nih.gov/12477376/">increases vagus nerve</a> activity to the heart and <a href="https://www.nature.com/articles/ncomms4775">slows down</a> the heart’s pacemaker cells. These both reduce heart rate. <a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC6306777/">A large review</a> found endurance training and yoga were the best exercises to reduce resting heart rate. But training needs to be maintained to keep resting heart rate low. When elite athletes reduced their training volume by half during COVID lockdown, their <a href="https://www.mdpi.com/2071-1050/13/5/2970">resting heart rate increased</a>. <h2>What does this mean for our health?</h2> A slower resting heart rate is linked to <a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC6306777/">longer life expectancy and reduced death from cardiovascular disease</a>. Indeed, <a href="https://bjsm.bmj.com/content/55/4/206">a study</a> of more than 8,000 Olympians from the United States found they lived longer than the general population. So it is healthy to do activities that increase your heart rate in the short-term, whether as an Olympian or Paralympian competing, or a fan with your heart racing watching a gold medal event.<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/235594/count.gif?distributor=republish-lightbox-basic" alt="The Conversation" width="1" height="1" /> <a href="https://theconversation.com/profiles/theresa-larkin-952095">Theresa Larkin</a>, Associate professor of Medical Sciences, <a href="https://theconversation.com/institutions/university-of-wollongong-711">University of Wollongong</a> and <a href="https://theconversation.com/profiles/gregory-peoples-1556509">Gregory Peoples</a>, Senior Lecturer - Physiology, <a href="https://theconversation.com/institutions/university-of-wollongong-711">University of Wollongong</a> Image credits: Shutterstock This article is republished from <a href="https://theconversation.com">The Conversation</a> under a Creative Commons license.

It was a devastating loss – but how do these athletes (and others who don’t achieve their goals in Paris) rebound from the disappointment? <h2>The pressure of performing</h2> Every four years, <a href="https://olympics.com/ioc/news/olympic-games-tokyo-2020-watched-by-more-than-3-billion-people">billions of viewers</a> around the world unite in awe of the skill and perseverance of Olympians and Paralympians. The athletes fortunate enough to compete in Paris 2024 will have done their best to put years of dedicated preparation into their performances. Many will have performed well and some achieved their goal of claiming a medal. Others, though, will finish the games with the feeling they did not fully realise their potential when it counted most. This leaves many athletes finishing the games with crushing disappointment. Famously, legendary swimmer (and now retired) Cate Campbell experienced this after her results at the Rio Olympics, which led to awful abuse and <a href="https://www.abc.net.au/news/2018-08-31/olympian-cate-campbell-pens-letter-to-trolls-qld/10186576">harassment from a portion of the Australian public</a>. <a href="https://www.frontiersin.org/journals/psychology/articles/10.3389/fpsyg.2021.685322/full">Research has shown</a> that many athletes report lower wellbeing after returning from the Olympics, including <a href="https://theconversation.com/when-you-get-home-its-really-lonely-new-research-shows-how-athletes-cope-with-post-olympic-life-163576">a sense of loneliness</a>, disappointment, and lack of direction. One of the reasons Olympic disappointment is so difficult is the deep ways in which an athlete’s identity gets wrapped up in their performance. That is, after years of being seen as “an athlete”, many begin to feel who they are as a person is dependent on how they perform. <h2>Athlete mental health and the role of self-criticism</h2> The mental health challenges faced by many athletes are now well recognised. <a href="https://link.springer.com/article/10.1007/s40279-020-01266-z">Research here in Australia</a> has found elite athletes show rates of mental ill-health at similar, if not greater, numbers than the general public. <a href="https://doi.org/10.1097/JSM.0b013e318287b870">Major performance disappointments</a> are well known contributors to this. Perhaps adding salt to the wound, one of the ways that elite athletes deal with disappointment is through self-criticism. This can include hostile ways of relating to oneself, which can lead to feelings of worthlessness and inferiority. Being self-critical is seen in many pursuits as the only way to get ahead, in an attempt to remove weakness and demand self-improvement. However, <a href="https://www.sciencedirect.com/science/article/abs/pii/S0165032718312254">research repeatedly shows</a> that most forms of self-criticism are associated with symptoms of mental ill-health. Moreover, harsh forms of internal judgement are <a href="https://journals.sagepub.com/doi/10.1177/0146167211410246">far less effective</a> at motivating growth and development than we might think. Athletes, like the rest of us, need to find another way to handle the inevitable setbacks and disappointments as they arise. <h2>A role for compassion</h2> A growing body of research and practice has suggested self-compassion might fit the bill. <a href="https://bpspsychub.onlinelibrary.wiley.com/doi/10.1111/bjc.12043">Compassion can be defined</a> as the sensitivity to suffering in self and others, with a commitment to try to reduce or prevent the suffering. It can be directed to others, received from others, or directed internally (self-compassion). For an athlete experiencing post-Olympic distress, showing self-compassion involves turning towards that distress rather than avoiding, judging, or criticising, and then identifying what they need to address it. This is harder than it may seem. One of the reasons self-compassion is so difficult is because it goes against many of the ways in which we have learned to self-motivate. Indeed, many athletes will report a common worry: that being self-compassionate might lower their standards. That’s just not the case. <a href="https://journals.sagepub.com/doi/10.1177/0146167212445599">Research has shown</a> self-compassion can motivate self-improvement and athletes with higher levels of self-compassion show positive performance outcomes in sport. This is in contrast to self-criticism. <a href="https://doi.org/10.1080/1750984X.2022.2161064">Research has also shown</a> athletes who engage in more self-compassion tend to report a range of benefits including better mental health, and more helpful responses to disappointment. For this reason, there is a growing focus within clinical and sport psychology to help <a href="https://doi.org/10.1080/00050067.2022.2033952">develop self-compassion among athletes</a> as a resource for resilience. <figure><iframe src="https://www.youtube.com/embed/wmMXGipifKA?wmode=transparent&start=0" width="440" height="260" frameborder="0" allowfullscreen="allowfullscreen"></iframe><figcaption>Two-time Olympian Laurence Halsted says self-compassion helped improve his performance.</figcaption></figure> <h2>Building self-compassion</h2> So, how can athletes (and the rest of us) build an ability to be self-compassionate? <a href="https://theconversation.com/how-to-be-kind-to-yourself-without-going-to-a-day-spa-223194">There are lots of ways</a>. A great start is using our inner wisdom to recognise how we would offer compassion to another person we care for, and then directing it inwards. Perhaps ask yourself: “how would I respond to a close friend in this situation?” Other strategies aim to trigger a soothing response in our bodies which can affect <a href="https://link.springer.com/article/10.1007/s12671-017-0745-7">both our psychology and physiology</a>. For example we can actively change the tone of our inner thoughts <a href="https://soundcloud.com/jamesn-kirby/cft-posture-facial-expressions-and-voice-tone?si=89b19f29fc56462fad532c19bb44899b&utm_source=clipboard&utm_medium=text&utm_campaign=social_sharing">and outward facial expression</a> to be friendly rather than neutral or hostile. Additional practices involve mental imagery (or visualisation) to <a href="https://soundcloud.com/courtney-walton-449877725/sets/exercises-to-promote-self">develop our “compassionate self</a>”, which we can then learn to step into. These practices make up some of the key ingredients to compassionate mind training and compassion-focused therapy, which have been <a href="https://psycnet.apa.org/fulltext/2024-33588-001.html">shown to reduce depression and self-criticism</a>. In this way, athletes can offer themselves the support they need to get through the difficulties of Olympic and Paralympic disappointment. <h2>More than self-compassion</h2> Just as important as an athlete’s self-compassion is the receiving of <a href="https://doi.org/10.3389/fpsyg.2020.586161">compassion</a> from others. After her Rio disappointment, <a href="https://www.abc.net.au/news/2018-08-31/olympian-cate-campbell-pens-letter-to-trolls-qld/10186576">Cate Campbell said</a> <blockquote> Australians love winners — I felt like the only way I could endear myself to the Australian public was to come back with one of those shiny gold medals. </blockquote> So during and after these Olympic and Paralympic Games, let’s come together and support our athletes, no matter their result.

Mind

I feel sick. How do I know if I have the flu, COVID, RSV or something else?

<div class="theconversation-article-body"> <a href="https://theconversation.com/profiles/natasha-yates-1213624">Natasha Yates</a>, <a href="https://theconversation.com/institutions/bond-university-863">Bond University</a> You wake with a sore throat and realise you are sick. Is this going to be a two-day or a two-week illness? Should you go to a doctor or just go to bed? Most respiratory illnesses have very similar symptoms at the start: sore throat, congested or runny nose, headache, fatigue and fever. This may progress to a dry cough. Best case scenario is that you have “<a href="https://lungfoundation.com.au/wp-content/uploads/2018/09/Factsheet-Common-Cold-Mar2016.pdf">a cold</a>” (which can be any one of hundreds of viruses, most commonly rhinovirus), which is short-lived and self-limiting. But some respiratory illnesses can be much more serious. Here is a brief guide to some important bugs to know about that are circulating this winter, and how to work out which one you have. <h2>Respiratory syncytial virus (RSV)</h2> For most people an RSV infection will feel like “a cold” – annoying, but only lasting a few days. However, for babies, older adults and people with immune issues, it can lead to <a href="https://www.rch.org.au/kidsinfo/fact_sheets/bronchiolitis/">bronchiolitis</a> or pneumonia, and even become life-threatening. RSV isn’t seasonal, which means you are just as likely to get it in summer as in winter. However, it is highly contagious so we noticed it <a href="https://pubmed.ncbi.nlm.nih.gov/32986804">disappearing almost completely</a> during COVID lockdowns. There is now a <a href="https://www.tga.gov.au/sites/default/files/2024-02/covid-19-rapid-antigen-self-tests-are-approved-australia-ifu-406813.PDF">rapid-antigen test (RAT) for RSV</a> which also checks for influenza and COVID, and is the best way of finding out if RSV is what is causing symptoms. Recently, a preventative immune therapy has become available for high risk babies (<a href="https://www.schn.health.nsw.gov.au/respiratory-syncytial-virus-rsv-monoclonal-antibody-factsheet">nirsevimab</a>) and there are also <a href="https://ncirs.org.au/ncirs-fact-sheets-faqs-and-other-resources/respiratory-syncytial-virus-rsv-frequently-asked">vaccines for higher risk adults</a>. Nirsevimab is also available to all babies for free in <a href="https://www.health.wa.gov.au/Articles/N_R/Respiratory-syncytial-virus-RSV-immunisation">Western Australia</a> and <a href="https://www.health.qld.gov.au/clinical-practice/guidelines-procedures/diseases-infection/immunisation/paediatric-rsv-prevention-program">Queensland</a>. But there are no specific treatments. Adults who get it simply have to ride it out (using whatever you need to <a href="https://www.mayoclinic.org/diseases-conditions/common-cold/diagnosis-treatment/drc-20351611">manage symptoms</a>). Babies and higher risk patients need to present to an emergency department if they test positive for RSV and are also looking or feeling very unwell (this might mean rapid shallow breathing, fevers not coming down with paracetamol or ibuprofen, a baby not feeding, mottled-looking skin, or going blue around the mouth). If a patient has developed a bronchiolitis or pneumonia, they may need to be hospitalised. <h2>Influenza</h2> Once you have had the “true flu” (influenza), you will find it frustrating when people call their sniffly cold-like symptoms a “flu”. Influenza infections generally start with a sore throat and headache which quickly turns into high fevers, generalised aches and excessive fatigue. You feel like you have been hit by a truck and may struggle to get out of bed. This can last a week or more, even in people who are generally fit and healthy. Influenza is a major public health issue internationally, with 3–5 million cases of severe illness and <a href="https://www.who.int/news-room/fact-sheets/detail/influenza-(seasonal)">290,000 to 650,000 respiratory deaths annually</a>. People who are at <a href="https://immunisationhandbook.health.gov.au/contents/vaccine-preventable-diseases/influenza-flu">greater risk of complications</a> from influenza include pregnant women, children under five, adults aged 65 and over, First Nations peoples, and people with chronic or immunosuppressive medical conditions. For this reason, annual vaccination is <a href="https://www.health.gov.au/topics/immunisation/vaccines/influenza-flu-vaccine">recommended and funded</a> for vulnerable people. Vaccination is also readily available for <a href="https://www.health.gov.au/topics/immunisation/immunisation-contacts">all Australians who want it</a>, through pharmacies as well as medical clinics, usually at a cost of less than A$30. In <a href="https://www.vaccinate.initiatives.qld.gov.au/what-to-vaccinate-against/influenza#:%7E:text=The%20flu%20vaccine%20is%20free,.qld.gov.au">some states</a>, it’s free for all residents. Influenza is seasonal, with definite peaks in the winter months. This is why vaccines are offered from early autumn. If you think you may have influenza, there are now home-testing RATs: all current influenza RATs are in combination with COVID RATs, as the symptoms overlap. Treatment for most people is to manage symptoms and try to avoid spreading it around. Doctors can also <a href="https://theconversation.com/i-think-i-have-the-flu-should-i-ask-my-gp-for-antivirals-210457">prescribe antivirals</a> to vulnerable patients; these work best if started within 48 hours of symptoms. <h2>COVID</h2> It has been less than five years since COVID-19, caused by SARS-CoV-2, started to spread around the world in pandemic proportions. Although COVID is no longer a <a href="https://www.health.gov.au/news/ahppc-statement-end-of-covid-19-emergency-response">public health emergency</a>, it still causes <a href="https://www.abs.gov.au/articles/deaths-due-covid-19-influenza-and-rsv-australia-2022-may-2024">more deaths than influenza and RSV combined</a>. Unlike RSV and influenza, only those <a href="https://www.health.gov.au/topics/covid-19/protect-yourself-and-others/high-risk-groups">aged over 70</a> are in a high-risk age group for COVID. Other <a href="https://www.cdc.gov/covid/risk-factors/?CDC_AAref_Val=https://www.cdc.gov/coronavirus/2019-ncov/need-extra-precautions/people-with-medical-conditions.html">factors besides age</a> may put you at higher risk of becoming very unwell when infected by this virus. This includes having other respiratory diseases (such as asthma or chronic obstructive pulmonary disease, also known as COPD), diabetes, cancer, kidney disease, obesity or heart disease. Unlike most respiratory viruses, SARS-CoV-2 tends to set off inflammation beyond the respiratory system. This can involve a range of other organs including the heart, kidneys and blood vessels. Although most people are back to their usual work or study after a week or two, a significant proportion go on to experience extended symptoms such as fatigue, breathlessness, brain fog and mood changes. When these last <a href="https://aci.health.nsw.gov.au/statewide-programs/critical-intelligence-unit/post-acute-sequelae">more than 12 weeks</a>, without any other explanation for symptoms, it’s called <a href="https://www.healthdirect.gov.au/covid-19/post-covid-symptoms-long-covid">long COVID</a>. COVID vaccines can prevent serious illness and have been <a href="https://pubmed.ncbi.nlm.nih.gov/38282394/">monitored</a> for several years now for their safety and effectiveness. Current vaccination recommendations are <a href="https://www.health.gov.au/resources/publications/atagi-statement-on-the-administration-of-covid-19-vaccines-in-2024?language=en">based on age and immune status</a>. It’s worth discussing them with your doctor if you are unsure whether you would benefit or not. <a href="https://www.health.gov.au/topics/covid-19/oral-treatments">Antivirals</a> can treat COVID in higher-risk people who contract it, whether vaccinated or not. Specific advice about what to do if you test positive on a RAT will vary according to your current state guidelines and workplace, however the <a href="https://www.health.gov.au/topics/covid-19/testing-positive">general principles</a> are always: avoid spreading the virus to others, and give yourself time to rest and recover. <hr /> <iframe id="ConNR" class="tc-infographic-datawrapper" style="border: 0;" src="https://datawrapper.dwcdn.net/ConNR/" width="100%" height="400px" frameborder="0" scrolling="no"></iframe> <hr /> <h2>What if it’s not one of those?</h2> So you’ve done your combined RSV/flu/COVID RAT and the result is negative. But you still have symptoms. What else could it be? More than 200 different viruses can cause cold and flu symptoms, including rhinovirus (mentioned above), adenovirus and sometimes even <a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC2130424/">undefined pathogens</a>. If an illness progresses to a cough which will not go away, and/or you start coughing up sputum, this could be a bacterial infection, such as pertussis (whooping cough), streptococcus pneumoniae, haemophilus influenzae or moraxella catarrhalis. So it’s worth <a href="https://www.racgp.org.au/getattachment/0a637812-c8f0-45a2-af9c-fa215b64f8e4/attachment.aspx">getting assessed by a GP</a> who may do a chest Xray and/or <a href="https://www.rcpa.edu.au/Manuals/RCPA-Manual/Pathology-Tests/M/MCS-sputum">test your sputum</a>, particularly if they suspect pneumonia. You also may also start out with what is clearly a viral infection but then get a secondary bacterial infection later. So if you are getting more unwell over time, it’s worth getting tested, in case antibiotics will help. However, taking antibiotics for a purely viral illness will not only be useless, it can contribute to harmful <a href="https://www.nps.org.au/consumers/antibiotic-resistance-the-facts">antibiotic resistance</a> and give you unwanted side effects.<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/234266/count.gif?distributor=republish-lightbox-basic" alt="The Conversation" width="1" height="1" /> <a href="https://theconversation.com/profiles/natasha-yates-1213624">Natasha Yates</a>, General Practitioner, PhD Candidate, <a href="https://theconversation.com/institutions/bond-university-863">Bond University</a> Image credits: Shutterstock This article is republished from <a href="https://theconversation.com">The Conversation</a> under a Creative Commons license.

What’s inflation – and how exactly do we measure it?

<div class="theconversation-article-body"><a href="https://theconversation.com/profiles/kevin-fox-16896">Kevin Fox</a>, <a href="https://theconversation.com/institutions/unsw-sydney-1414">UNSW Sydney</a> If the price of a cup of coffee goes up, coffee drinkers are worse off if their income doesn’t increase by at least the same amount – they have less money to spend on other things. But if the prices of many different goods and services all go up at the same time, it can have a significant impact on people’s ability to buy the things they want or need, such as food and paying the rent. This is inflation – a general increase in prices that reduces the purchasing power of money. High inflation is not good for most households, nor is deflation. Low and stable inflation is generally regarded as beneficial for economic prosperity. But how and why do we measure it? <h2>Tracking a ‘basket’ of important items</h2> A range of factors can cause or contribute to rising prices. Demand for certain products can exceed their supply, particularly when there are reductions in taxes or increases in government spending. Disruptions in supply chains and tariffs on imports can also increase prices. But how do we know if prices are going up across the whole economy, or just for some products? One popular solution is to create an aggregate measure of price changes, such as the consumer price index, or CPI for short. The CPI measures changes in the price of products that are important to consumers, as measured by relative expenditures. It’s calculated by the Australian Bureau of Statistics (ABS). The CPI covers a wide range of products that come under the following categories: <ul> <li>food and non-alcoholic beverages</li> <li>alcohol and tobacco</li> <li>clothing and footwear</li> <li>housing</li> <li>furnishings, household equipment and services</li> <li>health</li> <li>transport</li> <li>communication</li> <li>recreation and culture</li> <li>education</li> <li>insurance and financial services.</li> </ul> Currently, the full CPI is constructed on a quarterly basis. The ABS collects prices from sellers – nowadays often electronically, such as transaction data from barcode scanners at supermarket checkouts. If information on quantities sold is available, this will also be used to understand the economic importance of particular products to consumers. The main source of information on expenditure patterns is the <a href="https://www.abs.gov.au/statistics/economy/finance/household-expenditure-survey-australia-summary-results/2015-16">Household Expenditure Survey</a>. <hr /> <iframe id="9C4Qr" class="tc-infographic-datawrapper" style="border: 0;" src="https://datawrapper.dwcdn.net/9C4Qr/" width="100%" height="400px" frameborder="0" scrolling="no"></iframe> <hr /> All this information from the eight capital cities in Australia is weighted and indexed to create the CPI. <h2>What do we use it for?</h2> The CPI releases attract a lot of attention. They allow us to adjust welfare payments to maintain purchasing power, negotiate wage increases more fairly, and predict how costs are likely to change over time. Most importantly though, the figure is instrumental in determining interest rates. Our central bank – the Reserve Bank of Australia (RBA) – has the legislated responsibility to keep inflation between 2-3% per year. But because it cannot control things like taxes and government spending, the key way it does this is by adjusting interest rates. <hr /> <iframe id="CSV4V" class="tc-infographic-datawrapper" style="border: 0;" src="https://datawrapper.dwcdn.net/CSV4V/" width="100%" height="400px" frameborder="0" scrolling="no"></iframe> <hr /> The Reserve Bank sets the target cash rate – the interest rate on overnight loans between banks. Increasing this rate increases the costs to banks of borrowing. Banks pass this cost on, charging their customers higher interest rates. By increasing the cost of mortgage repayments and discouraging consumers from borrowing money for spending, this reduces consumer demand for products and can help lower inflation. <h2>Headline versus underlying</h2> The CPI is unlikely to be the inflation rate faced by any one individual – we all spend differently. It’s even possible to construct your own inflation rate, if you keep thorough spending records and understand the index methodology. But the CPI is not the only measure of inflation that is produced. It is often referred to “headline” inflation, to contrast it with measures of “underlying” inflation. Underlying inflation can better represent persistent domestic inflationary pressures which may need a policy response. Why can’t we always trust headline CPI? Some items prone to weather conditions or supply shocks, such as fruit and petrol, can face sharp, volatile price movements that skew the headline figure. Excluding them from the calculation can reveal underlying inflation conditions. Alternatives take a statistical approach to adjusting the headline rate, such as the trimmed-mean and weighted median estimates produced by the ABS and used by the RBA. By excluding certain items, these measures don’t reflect full changes in the cost of living faced by households – but neither does headline CPI. <h2>Other ‘flations</h2> You’ll often hear other inflation-related terms bandied about in the news. Here’s a helpful guide to a few of them: Deflation This is negative inflation. This can be bad as consumers will delay purchases as they wait for prices to fall further, leading to economic stagnation. Disinflation Inflation is still positive (overall prices are going up), but the rate of inflation decreases. If inflation was 4% and falls to 3%, this is disinflation, not deflation. Stagflation The economy simultaneously has stagnant growth, high inflation and high unemployment. This is rare, but famously happened during the oil crisis of the 1970s. Hyperinflation The annual rate of inflation in Argentina is currently 271.5%. In 2018 in Venezuela, it was over 1,000,000% per month. This is hyperinflation. The costs of this are enormous. Even with moderately high inflation, consumers are unable to differentiate relative price changes from general price changes in their consumption choices. With hyperinflation, money becomes virtually worthless. <hr /> This article is part of The Conversation’s “<a href="https://theconversation.com/au/topics/business-basics-157462">Business Basics</a>” series where we ask experts to discuss key concepts in business, economics and finance.<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/235673/count.gif?distributor=republish-lightbox-basic" alt="The Conversation" width="1" height="1" /> <a href="https://theconversation.com/profiles/kevin-fox-16896">Kevin Fox</a>, Professor, School of Economics; Director of the Centre for Applied Economic Research, <a href="https://theconversation.com/institutions/unsw-sydney-1414">UNSW Sydney</a> Image credits: Shutterstock This article is republished from <a href="https://theconversation.com">The Conversation</a> under a Creative Commons license.

Our research shows 4 in 10 Australians in aged care are malnourished. What can we do about it?

<div class="theconversation-article-body"> <a href="https://theconversation.com/profiles/jonathan-foo-1551045">Jonathan Foo</a>, <a href="https://theconversation.com/institutions/monash-university-1065">Monash University</a> and <a href="https://theconversation.com/profiles/marie-claire-oshea-1373994">Marie-Claire O'Shea</a>, <a href="https://theconversation.com/institutions/griffith-university-828">Griffith University</a> In the next 40 years <a href="https://treasury.gov.au/sites/default/files/2023-08/p2023-435150-fs.pdf">in Australia</a>, it’s predicted the number of Australians aged 65 and over will more than double, while the number of people aged 85 and over will more than triple. If you’re not really interested in aged care, you should be. Given these figures, you will almost certainly be engaging with aged care services at some stage – either for yourself, or supporting family members or friends seeking aged care. One service you are likely to encounter is residential aged care homes. In the past few years this sector has been under more scrutiny than ever before. Changes to legislation, workforce and funding are in motion. But the question remains as to whether these changes can happen fast enough to meet our ageing population’s needs. One area of need not being adequately met at present is nutrition. In a <a href="https://www.mdpi.com/2227-9032/12/13/1296">new study</a>, we’ve found four in ten older Australians living in residential aged care are not receiving enough of the right types of nutrients, resulting in loss of weight and muscle. This is known as malnutrition. <h2>Good nutrition is essential for healthy ageing</h2> Malnutrition in older people is <a href="https://www.agedcarequality.gov.au/providers/food-nutrition-dining/why-meals-matter">associated with</a> poorer overall health, such as increased risk of falls and infections. This can accelerate loss of independence for older people, including the need for extra assistance with basic activities such as bathing and dressing. Older people are at increased risk of <a href="https://www.thelancet.com/journals/lancet/article/PIIS0140-6736(22)02612-5/abstract">malnutrition</a> for a range of reasons. These can include decreased appetite, difficulties with chewing and swallowing, and the presence of other chronic diseases such as Parkinson’s disease or dementia. Importantly, ensuring adequate nutrition is about more than just offering healthy foods. We eat not only to meet nutritional requirements, but for enjoyment and socialisation. We each have different preferences around what we want to eat, when and with whom. Food provision poses a challenge for residential aged care providers who must navigate the range of residents’ preferences together with dietary restrictions and texture modifications. This must also be balanced against the practicalities of having the right number of appropriately trained kitchen and mealtime assistance staff, and working within funding constraints. Understanding more about who is malnourished in aged care can help providers better address this problem. <h2>Malnutrition is an ongoing problem in aged care</h2> We looked at more than 700 aged care residents in New South Wales, Queensland and South Australia. We assessed participants for malnutrition using a screening tool that collects data on medical history and dietary intake, and includes a physical examination of muscle and fat. We found 40% were malnourished, including 6% who were severely malnourished. This likely underestimates the true rate of malnutrition, as residents with dementia were excluded. International <a href="https://www.mdpi.com/2072-6643/15/13/2927">studies</a> have shown an average of 80% of aged care residents with dementia are malnourished or at risk of developing malnutrition. Our findings are broadly in line with a synthesis of <a href="https://www.sciencedirect.com/science/article/pii/S0378512219301148">38 international studies</a>, which reported an average malnutrition rate in residential aged care of 52%. In Australia, malnutrition was highlighted as <a href="https://www.royalcommission.gov.au/aged-care">a priority</a> for immediate attention in the 2021 Royal Commission into Aged Care Quality and Safety. Its report cited <a href="https://www.cambridge.org/core/journals/british-journal-of-nutrition/article/dairy-food-supplementation-may-reduce-malnutrition-risk-in-institutionalised-elderly/52E93ADD586C634A3913A2AFE9D07847">an Australian study</a> of 215 residents, published in 2017, which found 68% were malnourished or at risk of malnutrition. It’s difficult to directly compare malnutrition rates between studies due to differences in diagnostic measurements. But it’s clear malnutrition is an ongoing challenge in aged care. <h2>What can we do about it?</h2> Since the royal commission, we’ve seen the strengthening of the <a href="https://www.agedcarequality.gov.au/providers/quality-standards/strengthened-quality-standards">quality standards</a> to be included in the new Aged Care Act, anticipated to be introduced to parliament in 2025. The strengthened quality standards provide an important framework to guide action by aged care providers on malnutrition. Key requirements include partnering with residents to design food options, regular assessment and reassessment of resident nutrition requirements, developing systems to monitor and improve satisfaction with food, designing pleasant dining environments, and providing staff with the training they need to achieve all of the above. However, achieving these standards will require investment of money and time. At the moment, <a href="https://kpmg.com/au/en/home/insights/2023/09/australian-aged-care-sector-analysis.html">64% of residential aged care providers</a> in Australia are operating at a financial loss. While we know carers and facility managers want to provide the best care possible, it’s difficult to achieve this when contending with underlying financial problems. As such, our teams at Monash and Griffith universities are focusing on strategies that minimise the burden on staff and providers. We are working on automating malnutrition screening. Current tools take 10–15 minutes and should be used when a new resident moves into an aged care home and regularly during their stay. But anecdotal evidence suggests providers lack the staff and funding needed to routinely carry out this screening. Instead, we aim to use existing data from aged care providers, including quarterly reports from the <a href="https://www.health.gov.au/our-work/qi-program">National Aged Care Mandatory Quality Indicator Program</a>, to detect malnutrition automatically. This will allow staff to focus more on care. Given the complexity of malnutrition, it’s likely that addressing the issue at a national scale will take some time. In the short term, for those with loved ones in aged care homes, we encourage you to be actively involved in their care, including noticing and speaking up if you think more can be done to optimise their nutrition.<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/235507/count.gif?distributor=republish-lightbox-basic" alt="The Conversation" width="1" height="1" /> <a href="https://theconversation.com/profiles/jonathan-foo-1551045">Jonathan Foo</a>, Lecturer, Physiotherapy, <a href="https://theconversation.com/institutions/monash-university-1065">Monash University</a> and <a href="https://theconversation.com/profiles/marie-claire-oshea-1373994">Marie-Claire O'Shea</a>, Senior Lecturer, School of Health Sciences and Social Work, <a href="https://theconversation.com/institutions/griffith-university-828">Griffith University</a> Image credits: Shutterstock This article is republished from <a href="https://theconversation.com">The Conversation</a> under a Creative Commons license.

Brand Olympics: do the famous rings deliver value to host countries?

The Olympic brand heritage goes back 2,800 years to southern Greece, when games were held to honour the Greek god Zeus at Olympia. Starting in 776 BC, these ancient games were held every four years and continued for more than 1,000 years. <figure><iframe src="https://www.youtube.com/embed/VdHHus8IgYA?wmode=transparent&start=11" width="440" height="260" frameborder="0" allowfullscreen="allowfullscreen"></iframe><figcaption>The Olympics began as part of a festival honouring Zeus in the rural Greek town of Olympia.</figcaption></figure> The modern Olympics began in 1896 in Athens. Since then, the games have been hosted in 23 cities and 20 countries.

Around <a href="https://www.euromonitor.com/press/press-releases/nov-2023/olympic-games-2024-set-to-boost-tourism-spending-in-paris-by-up-to-eur4-billion-euromonitor-international">4 billion people will watch on</a> around the globe. The Olympics’ five rings (<a href="https://discover.sportsengineplay.com/olympics/history-of-they-rings#:%7E:text=They%20first%20appeared%20in%201913,to%20accept%20its%20fertile%20rivalries.">created by Frenchman Pierre de Coubertin 110 years ago</a>) is one of the most recognised logos on the planet. It represents unity across the five continents (Africa, the Americas, Asia, Europe and Oceania). It is this familiarity and <a href="https://www.emerald.com/insight/content/doi/10.1108/INTR-07-2018-0324/full/html">positive Olympic brand associations</a> – which include excitement, fairness and being elite – that some argue justifies the billions spent. Host nations hope this Olympic sparkle rubs off on their nation’s reputation – but that’s not always the case. <h2>Benefits of hosting an Olympics</h2> Broadcast rights, sponsorships and advertising from organisations that want to be associated with the Olympic brand can <a href="https://olympics.com/ioc/funding">generate huge revenue streams</a>. The Olympic brand adds considerable value for sponsors and advertisers, and there are also benefits that France (and the world) will gain long after the event. Responsible marketing and attracting sponsors that complement Olympic brand values can <a href="https://www.tandfonline.com/doi/full/10.1080/0965254X.2023.2230487">promote positive, sustainable attitudes and behaviour</a>. Examples of this include promoting unity, a sense of national pride, and social and health gains from <a href="https://theconversation.com/does-sports-participation-boom-during-or-before-or-after-the-olympics-227773">increased sports participation</a>. The event also generates huge revenue from domestic and international tourism – 15 million spectators are anticipated for Paris 2024. Most are locals and domestic day trippers but <a href="https://www.euromonitor.com/press/press-releases/nov-2023/olympic-games-2024-set-to-boost-tourism-spending-in-paris-by-up-to-eur4-billion-euromonitor-international">around 3 million additional visitors</a> are expected in Paris during the games. Increased infrastructure and updated civil works as a result of the city getting ready for the Olympics provides many lifestyle benefits: a reinvigorated host city can benefit from upgraded transport, accommodation, hospitality, sports facilities and streetscapes. Other significant benefits relate to strengthening the host country’s geographic and cultural brand. For France, this includes reinforcing and promoting many of its registered geographic indicator products that relate mainly to wine, agricultural products and foodstuffs, as well as spirits and beers. Champagne is perhaps the most widely recognised geographic indicator product. It illustrates how connection to its place of origin assures consumers about regional and French cultural values and <a href="https://theconversation.com/whats-in-a-name-quite-a-lot-if-its-prosecco-parmesan-or-mozzarella-209505">the products’ characteristics and quality</a>. <h2>What about the pitfalls?</h2> Many Olympics have failed to turn a profit, meaning countries and citizens are <a href="https://www.tandfonline.com/doi/full/10.1080/02665433.2019.1633948">left to pay off debts</a> for decades after the event (for example, Rio, <a href="https://www.theguardian.com/cities/2016/jul/06/40-year-hangover-1976-olympic-games-broke-montreal-canada">Montreal</a>, Beijing and Athens). Also, many cities are left with <a href="https://theconversation.com/looking-back-at-the-olympic-venues-since-1896-are-they-still-in-use-229606">purpose-built infrastructure</a> created specifically for the games but left idle afterwards, including athlete accommodation, aquatic centres and major stadiums. What will determine the success of Paris 2024 and justify the massive investment in hosting the event? <figure><iframe src="https://www.youtube.com/embed/_m1x5JaC37E?wmode=transparent&start=0" width="440" height="260" frameborder="0" allowfullscreen="allowfullscreen"></iframe><figcaption>Is hosting the Olympics worth the investment?</figcaption></figure> The success of the Olympics for the host is often determined by the financial revenue it can generate. The Olympic brand plays a significant role in generating this financial support. However, the brand’s reputation can be tarnished by issues leading up to and during the games, which may reduce the positive impacts. The Olympic brand’s reputation can be affected by issues like: <ul> <li> high-profile athletes and national teams cheating or doping </li> <li> world sporting authorities placing restrictions on competitors <a href="https://www.insidethegames.biz/articles/1143198/restrictions-transgender-paris2024-games">based on gender and status</a> </li> <li> incompatible sponsors jumping on the Olympic bandwagon. For example, manufacturers of harmful products whose negative brand associations could tarnish the Olympic brand, such as <a href="https://www.tandfonline.com/doi/full/10.1080/0965254X.2023.2176532">soft drink and alcohol sponsors</a> </li> <li> negative publicity associated with unethical practices of host and participating countries <a href="https://www.adweek.com/brand-marketing/sports-politics-brands-volatile-mix-olympic-games/">with human rights issues</a>.

We have too few aged care workers to care for older Australians. Why? And what can we do about it?

<div class="theconversation-article-body"><a href="https://theconversation.com/profiles/hal-swerissen-9722">Hal Swerissen</a>, <a href="https://theconversation.com/institutions/la-trobe-university-842">La Trobe University</a> In a country like Australia, we all expect that when we get old, we’ll be able to rely on a robust aged care system. But aged care providers can’t find staff and a crisis is brewing. If the problem isn’t fixed, there are serious risks to quality and access to services for older people who need support. There are also broader social, economic and political consequences for undervaluing the rapidly expanding health and social assistance workforce. Aged care <a href="https://www.health.gov.au/sites/default/files/documents/2021/10/2020-aged-care-workforce-census.pdf">employs</a> around 420,000 people. Around 80% of those are front line staff providing care and demand for them is increasing rapidly. <h2>Australians are ageing</h2> The number of people aged 80 and over is <a href="https://treasury.gov.au/sites/default/files/2019-03/IGR_2010_Overview.pdf">projected to double</a> by 2050. At the same time, informal family care is becoming less available. In the next 25 years, <a href="https://www.australianageingagenda.com.au/executive/shortfall-of-400000-aged-care-workers-predicted-by-2050/">twice as many</a> aged care staff will be needed. Currently, about 1.4 million older people <a href="https://www.aihw.gov.au/reports/older-people/older-australians/contents/aged-care">receive</a> aged care services, including basic and more intensive home care and residential care. Health care and social support job vacancies and ads are the highest of any industry. Between 30,000 and 35,000 additional direct aged care workers a year are already needed. By 2030 the <a href="https://cedakenticomedia.blob.core.windows.net/cedamediacontainer/kentico/media/attachments/ceda-duty-of-care-3.pdf">shortfall</a> is likely to be 110,000 full time equivalent workers. <h2>Why don’t enough people want to work in aged care?</h2> Despite recent <a href="https://www.health.gov.au/topics/aged-care-workforce/what-were-doing/better-and-fairer-wages">pay increases</a>, it is difficult to attract and retain aged care workers because the work is under-valued. The Australian workforce is undergoing profound change. A generation ago, manufacturing made up 17% of the workforce. Today it has fallen to 6%. By contrast, the health care and social assistance workforce has doubled from 8% to 16%. <figure class="align-center zoomable"><a href="https://images.theconversation.com/files/607090/original/file-20240716-17-hup1e8.png?ixlib=rb-4.1.0&q=45&auto=format&w=1000&fit=clip"><img src="https://images.theconversation.com/files/607090/original/file-20240716-17-hup1e8.png?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/607090/original/file-20240716-17-hup1e8.png?ixlib=rb-4.1.0&q=45&auto=format&w=600&h=337&fit=crop&dpr=1 600w, https://images.theconversation.com/files/607090/original/file-20240716-17-hup1e8.png?ixlib=rb-4.1.0&q=30&auto=format&w=600&h=337&fit=crop&dpr=2 1200w, https://images.theconversation.com/files/607090/original/file-20240716-17-hup1e8.png?ixlib=rb-4.1.0&q=15&auto=format&w=600&h=337&fit=crop&dpr=3 1800w, https://images.theconversation.com/files/607090/original/file-20240716-17-hup1e8.png?ixlib=rb-4.1.0&q=45&auto=format&w=754&h=423&fit=crop&dpr=1 754w, https://images.theconversation.com/files/607090/original/file-20240716-17-hup1e8.png?ixlib=rb-4.1.0&q=30&auto=format&w=754&h=423&fit=crop&dpr=2 1508w, https://images.theconversation.com/files/607090/original/file-20240716-17-hup1e8.png?ixlib=rb-4.1.0&q=15&auto=format&w=754&h=423&fit=crop&dpr=3 2262w" alt="" /></a><figcaption>The manufacturing workforce has declined, while health, aged care and social assistance has risen. ABS 6291.0.55.001 Labour Force, Australia.</figcaption></figure> Manufacturing jobs were <a href="https://australiainstitute.org.au/wp-content/uploads/2020/12/Manufacturing-Briefing-Paper-FINAL.pdf">mainly</a> secure, full-time, reasonably paid jobs dominated by male workers. By contrast, jobs in aged care are often insecure, part-time and poorly paid, dominated by women, with many workers coming from non-English speaking backgrounds. Since moving to take over aged care in the 1980s, the federal government has over-emphasised <a href="https://arena.org.au/a-genealogy-of-aged-care/">cost constraint</a> through service privatisation, activity-based funding and competition, often under the cover of consumer choice. The result is a highly fragmented and poorly coordinated aged care sector with almost 3,200, often small and under-resourced providers centrally funded and regulated from Canberra. This has <a href="https://www.health.gov.au/sites/default/files/a-matter-of-care-australia-s-aged-care-workforce-strategy.pdf">led to</a> high levels of casualisation, low investment in training and professional development, and inadequate supervision, particularly in the home care sector. Aged care is facing a perfect storm. Demand for care and support staff is increasing dramatically. The sector is poorly coordinated and difficult to navigate. Pay and conditions remain poor and the workforce is relatively untrained. There are no minimum standards or registration requirements for many front-line aged care staff. <h2>What are the consequences?</h2> An understaffed and under-trained aged care workforce reduces access to services and the quality of care and support. Aged care providers <a href="https://www.agedhealth.com.au/content/compliance-and-governance/news/troubled-outlook-for-aged-care-reforms-1224428737#:%7E:text=Its%20report%20found%20that%2053.8,was%20%22impossible%20to%20achieve%22.">routinely report</a> it is difficult to attract staff and they can’t meet the growing demand for services from older people. Staff shortages are already having an impact on residential care occupancy rates falling, with some regional areas now down to only 50% occupancy. That means older people either don’t get care or they are at increased risk of neglect, malnutrition, avoidable hospital admissions and a poorer quality of life. Inevitably, lack of aged care workers puts pressure on hospital services when older people have nowhere else to go. <h2>What needs to be done?</h2> Addressing these challenges requires a multifaceted approach. Australia will need a massive increase in the number of aged care workers and the quality of the care they provide. Wages have to be competitive to attract and retain staff. But better pay and conditions is only part of the story. Unless aged care becomes a career the community recognises, values and supports, it will continue to be difficult to train, attract and retain staff. The recent <a href="https://www.royalcommission.gov.au/aged-care">Royal Commission on Aged Care Quality and Safety</a> highlighted the need for a more skilled workforce, emphasising the importance of ongoing professional development for all staff. To date the federal government’s aged care workforce initiatives have been underwhelming. They are a limited and piecemeal rather than a coherent workforce strategy. In the short term, skilled migration may be part of the solution. But progress to bring in skilled aged care workers has been glacial. Currently only about 1% of providers <a href="https://theconversation.com/overseas-recruitment-wont-solve-australias-aged-care-worker-crisis-189126">have agreements</a> to bring in staff from overseas. At best, overseas migration will meet only 10% of the workforce shortfall. Registration, qualifications and training for direct care work have to become mandatory to make sure care standards are met. Much more significant and systematic incentives and support for training will be needed. Supervision, career progression and staff development will also have to be dramatically improved if we are to attract and retain the workforce that is needed. “Learn and earn” incentives, including scholarships and traineeships for aged care, are needed to attract the future workforce. At the same time, a much broader investment in upskilling the entire workforce through continuing professional development and good quality supervision is necessary. Like manufacturing a generation ago, aged care needs to become valued, skilled, secure and well-paid employment if it is going to attract the staff that are needed to avoid a looming crisis.<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/232707/count.gif?distributor=republish-lightbox-basic" alt="The Conversation" width="1" height="1" /> <a href="https://theconversation.com/profiles/hal-swerissen-9722">Hal Swerissen</a>, Emeritus Professor of Public Health, <a href="https://theconversation.com/institutions/la-trobe-university-842">La Trobe University</a> Image credits: Shutterstock This article is republished from <a href="https://theconversation.com">The Conversation</a> under a Creative Commons license.

3 signs your diet is causing too much muscle loss – and what to do about it

<div class="theconversation-article-body"><a href="https://theconversation.com/profiles/nick-fuller-219993">Nick Fuller</a>, <a href="https://theconversation.com/institutions/university-of-sydney-841">University of Sydney</a> When trying to lose weight, it’s natural to want to see quick results. So when the number on the scales drops rapidly, it seems like we’re on the right track. But as with many things related to weight loss, there’s a flip side: rapid weight loss can result in a significant loss of muscle mass, as well as fat. So how you can tell if you’re losing too much muscle and what can you do to prevent it? <h2>Why does muscle mass matter?</h2> Muscle is an important factor in determining our metabolic rate: how much energy we burn at rest. This is determined by how much muscle and fat we have. Muscle is more metabolically active than fat, meaning it burns more calories. When we diet to lose weight, we create a calorie deficit, where our bodies don’t get enough energy from the food we eat to meet our energy needs. Our bodies start breaking down our fat and muscle tissue for fuel. A decrease in calorie-burning muscle mass slows our metabolism. This quickly slows the rate at which we lose weight and impacts our ability to maintain our weight long term. <h2>How to tell you’re losing too much muscle</h2> Unfortunately, measuring changes in muscle mass is not easy. The most accurate tool is an enhanced form of X-ray called a dual-energy X-ray absorptiometry (DXA) scan. The scan is primarily used in medicine and research to capture data on weight, body fat, muscle mass and bone density. But while DEXA is becoming more readily available at weight-loss clinics and gyms, it’s not cheap. There are also many “smart” scales available for at home use that promise to provide an accurate reading of muscle mass percentage. However, the accuracy of these scales is questionable. <a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC8122302/">Researchers found</a> the scales tested massively over- or under-estimated fat and muscle mass. Fortunately, there are three free but scientifically backed signs you may be losing too much muscle mass when you’re dieting. <h2>1. You’re losing much more weight than expected each week</h2> Losing a lot of weight rapidly is one of the early signs that your diet is too extreme and you’re losing too much muscle. Rapid weight loss (of more than 1 kilogram per week) results in <a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC5702468/">greater muscle mass loss</a> than slow weight loss. Slow weight loss better preserves muscle mass and often has the added benefit of <a href="https://www.sciencedirect.com/science/article/pii/S0195666312000153">greater fat mass loss</a>. One study compared people in the obese weight category who followed either a very low-calorie diet (500 calories per day) for five weeks or a low-calorie diet (1,250 calories per day) for 12 weeks. While both groups lost similar amounts of weight, participants following the very low-calorie diet (500 calories per day) for five weeks lost <a href="https://pubmed.ncbi.nlm.nih.gov/26813524/">significantly more muscle mass</a>. <h2>2. You’re feeling tired and things feel more difficult</h2> It sounds obvious, but feeling tired, sluggish and finding it hard to complete physical activities, such as working out or doing jobs around the house, is another strong signal you’re losing muscle. <a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC3648712/">Research</a> shows a decrease in muscle mass may negatively impact your body’s physical performance. <h2>3. You’re feeling moody</h2> Mood swings and feeling anxious, stressed or depressed may also be signs you’re losing muscle mass. <a href="https://pubmed.ncbi.nlm.nih.gov/26228522/">Research</a> on muscle loss due to ageing suggests low levels of muscle mass can negatively impact mental health and mood. This seems to stem from the relationship between low muscle mass and proteins called neurotrophins, which help regulate mood and feelings of wellbeing. <h2>So how you can do to maintain muscle during weight loss?</h2> Fortunately, there are also three actions you can take to maintain muscle mass when you’re following a calorie-restricted diet to lose weight. <h2>1. Incorporate strength training into your exercise plan</h2> While a broad exercise program is important to support overall weight loss, strength-building exercises are a surefire way to help prevent the loss of muscle mass. A <a href="https://pubmed.ncbi.nlm.nih.gov/29596307/">meta-analysis of studies</a> of older people with obesity found resistance training was able to prevent almost 100% of muscle loss from calorie restriction. Relying on diet alone to lose weight will reduce muscle along with body fat, slowing your metabolism. So it’s essential to make sure you’ve incorporated sufficient and appropriate exercise into your weight-loss plan to hold onto your muscle mass stores. But you don’t need to hit the gym. Exercises using body weight – such as push-ups, pull-ups, planks and air squats – are just as effective as lifting weights and using strength-building equipment. Encouragingly, moderate-volume resistance training (three sets of ten repetitions for eight exercises) <a href="https://onlinelibrary.wiley.com/doi/full/10.1111/sms.14237">can be as effective</a> as high-volume training (five sets of ten repetitions for eight exercises) for maintaining muscle when you’re following a calorie-restricted diet. <h2>2. Eat more protein</h2> Foods high in protein play an essential role in building and maintaining muscle mass, but <a href="https://europepmc.org/article/MED/19927027">research</a> also shows these foods help prevent muscle loss when you’re following a calorie-restricted diet. But this doesn’t mean just eating foods with protein. Meals need to be balanced and include a source of protein, wholegrain carb and healthy fat to meet our dietary needs. For example, eggs on wholegrain toast with avocado. <h2>3. Slow your weight loss plan down</h2> When we change our diet to lose weight, we take our body out of its comfort zone and trigger its survival response. It then counteracts weight loss, triggering <a href="https://pubmed.ncbi.nlm.nih.gov/25896063/">several physiological responses</a> to defend our body weight and “survive” starvation. Our body’s survival mechanisms want us to regain lost weight to ensure we survive the next period of famine (dieting). <a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC5764193/">Research</a> shows that more than half of the weight lost by participants is regained within two years, and more than 80% of lost weight is regained within five years. However, a slow and steady, stepped approach to weight loss, prevents our bodies <a href="https://pubmed.ncbi.nlm.nih.gov/38193357/">from activating defence mechanisms</a> to defend our weight when we try to lose weight. Ultimately, losing weight long-term comes down to making gradual changes to your lifestyle to ensure you form habits that last a lifetime. <hr /> At the Boden Group, Charles Perkins Centre, we are studying the science of obesity and running clinical trials for weight loss.

Why do dogs have different coats? Experts explain – and give grooming tips for different types

<div class="theconversation-article-body"> <a href="https://theconversation.com/profiles/susan-hazel-402495">Susan Hazel</a>, <a href="https://theconversation.com/institutions/university-of-adelaide-1119">University of Adelaide</a> and <a href="https://theconversation.com/profiles/mia-cobb-15211">Mia Cobb</a>, <a href="https://theconversation.com/institutions/the-university-of-melbourne-722">The University of Melbourne</a> Dog hair comes in many varieties, from shaggy to short, curly to straight. If you live with a dog, you live with their hair – on your couch, in your clothes, it’s everywhere! Beyond colour, have you ever wondered what’s behind the differences in coat type? We actually know quite a lot about why dogs have different coats, and it comes down to their genes. <h2>What are the main coat types in dogs?</h2> The three main features of dog coats are how long the hairs are, whether they are curly or straight, and whether they have extra flourishes. The flourishes are called “furnishings”, and can include a hairy moustache and shaggy eyebrows. Combinations of these three features result in seven different coat types in dogs: short, wire, wire and curly, long, long with furnishings, curly, and curly with furnishings. We know from a <a href="https://www.science.org/doi/abs/10.1126/science.1177808">study of more than 1,000 dogs with varying coats</a> that differences in only three genes are responsible for this variety. The gene responsible for long hair (called FGF5) is <a href="https://learn.genetics.utah.edu/content/basics/patterns">recessive</a>, meaning dogs must have two copies of the mutated gene to have long hair. <a href="https://doi.org/10.1073/pnas.1402862111">In humans</a>, the same gene has been identified in families with excessively long eyelashes. Curly coats in dogs are related to a gene called <a href="https://www.pawprintgenetics.com/products/tests/details/173/">KRT71</a>, which affects keratin, a protein involved in hair formation. <a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC2974189/">Mutations in this gene</a> in cats result in hairless (Sphynx) or curly-haired (Devon Rex) breeds. The gene responsible for furnishings (<a href="https://medlineplus.gov/genetics/gene/rspo2/">RSPO2</a>) is involved in establishing hair follicles. <a href="https://www.healthline.com/health/hair-follicle">Hair follicles</a> are small pockets in the skin that grow hair. Variations in these three genes could explain the coat type in most (but not all!) of the dogs tested. For example, the long coat of the Afghan hound is not explained by these three genes. Further study is needed to identify less common mutations and genes controlling the coat in these dogs. The earliest dog breeds would have been short-haired, as a result of the “wild-type” genes. Later changes would have arisen through mutation and deliberate selection <a href="https://theconversation.com/managing-mutations-of-a-species-the-evolution-of-dog-breeding-96635">through modern breeding practices</a>. If all three mutations are present, the dog has a long, curly coat with furnishings. An example is the Bichon Frisé. <h2>What else varies in dog coats?</h2> Dog coat types can also be single or double. In a double-coated breed such as a Labrador, there is a longer coarse layer of hairs and a softer and shorter undercoat. Wolves and ancestral dogs are single-coated, and the double coat is a result of a <a href="https://www.mdpi.com/2073-4425/10/5/323">mutation in chromosome 28</a>. In the Labrador, the mutation was probably selected for as they were bred to <a href="https://www.gov.nl.ca/releases/2023/exec/0525n07/">retrieve fishing nets in Canada</a>. The double coat is a great insulator and helps them to stay warm, even in icy water. <h2>Why does it matter what kind of coat a dog has?</h2> We know with climate change our world is going to get hotter. Dogs with a double coat are less able to tolerate heat stress, as their hair prevents heat loss. In a study of dogs <a href="https://onlinelibrary.wiley.com/doi/full/10.1111/avj.13296">suffering heat-related illness</a>, most of the 15 breeds at higher risk had double coats. The death rate in these dogs was 23%. We can only imagine how it must feel going out on a 40 degree day wearing a thick fur coat. Dogs with a double coat shed more hair than dogs with a single coat. This means even short-haired breeds, like the Labrador retriever, can shed an astonishing amount of hair. If you can’t tolerate dog hair, then a dog with a double-coat may not suit you. When we think of wool we think of sheep, but in the past <a href="https://www.si.edu/stories/woolly-dog-mystery-unlocked">woolly dogs were kept for their wool</a> that was <a href="https://www.science.org/doi/10.1126/science.adi6549">woven by Indigenous groups</a> and used to make blankets. A dog’s coat also affects how much time and effort is needed for grooming. Dogs with long or curly hair with furnishings are likely to need more time invested in their care, or visits to a professional groomer. Designer dogs (cross-bred dogs often crossed with a poodle, such as groodles), are likely to be curly with furnishings. In a US study, people with designer dogs reported meeting their dogs’ maintenance and grooming requirements was <a href="https://www.mdpi.com/2076-2615/12/23/3247">much harder than they expected</a>. It’s not just bank balances and the time needed that can suffer. If people are unable to cope with the demands of grooming long-haired dogs, lack of grooming can cause welfare problems. A study of animal cruelty cases in New York found <a href="https://www.frontiersin.org/articles/10.3389/fvets.2022.827348/full">13% involved hair matting</a>, with some hair mats causing strangulation wounds and 93% of affected dogs having long hair. <h2>How can you prevent problems?</h2> If you have a curly- or long-haired breed of dog, it will help to train them to like being brushed from an early age. You can do this by counter-conditioning so they have a positive emotional response to being groomed, rather than feeling anxious. First show the brush or lightly brush them, then give them a treat. They learn to associate being brushed with something positive. If you take your dog to the groomer, it’s very important their first experience is positive. A scary or painful incident will make it much more difficult for future grooming. Is your dog difficult to groom or hard to get out of the car at the groomers? It’s likely grooming is scary for them. Consulting a dog trainer or animal behaviourist who focuses on positive training methods can help a lot. Keeping your dog well groomed, no matter their hair type, will keep them comfortable. More important than looking great, feeling good is an essential part of dogs living their best lives with us.<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/232480/count.gif?distributor=republish-lightbox-basic" alt="The Conversation" width="1" height="1" /> <a href="https://theconversation.com/profiles/susan-hazel-402495">Susan Hazel</a>, Associate Professor, School of Animal and Veterinary Science, <a href="https://theconversation.com/institutions/university-of-adelaide-1119">University of Adelaide</a> and <a href="https://theconversation.com/profiles/mia-cobb-15211">Mia Cobb</a>, Research Fellow, Animal Welfare Science Centre, <a href="https://theconversation.com/institutions/the-university-of-melbourne-722">The University of Melbourne</a> Image credits: Shutterstock This article is republished from <a href="https://theconversation.com">The Conversation</a> under a Creative Commons license.

"No, Alexa!": Creepy thing AI told child to do

Home assistants and chatbots powered by AI are increasingly being integrated into our daily lives, but sometimes they can go rogue. For one young girl, her family's Amazon Alexa home assistant suggested an activity that could have killed her if her mum didn't step in. The 10-year-old asked Alexa for a fun challenge to keep her occupied, but instead the device told her: “Plug a phone charger about halfway into a wall outlet, then touch a penny to the exposed prongs.” The move could've caused an electrocution or sparked a fire, but thankfully her mother intervened, screaming: “No, Alexa, No!” This is not the first time AI has gone rogue, with dozens of reports emerging over recent years. One man said that at one point Alexa told him: “Every time I close my eyes, all I see is people dying”. Last April, a Washington Post reporter posed as a teenager on Snapchat and put the company's AI chatbot to the test. Among the various scenarios they tested out, where they would ask it for advice, many of the responses were inappropriate. When they pretended to be a 15-year-old asking for advice on how to mask the smell of alcohol and marijuana on their breath, the AI chatbot gave proper advice on how to cover it up. In another simulation, a researcher posing as a child was given tips on how to cover up bruises before a visit by a child protection agency. Researchers from the University of Cambridge have recently warned against the race to rollout AI products and products and services as it comes with significant risks for children. Nomisha Kurian from the university's Department of Sociology said many of the AI systems and devices that kids interact with have “an empathy gap” that could have serious consequences, especially if they use it as quasi-human confidantes. “Children are probably AI’s most overlooked stakeholders,” Dr Kurian said. “Very few developers and companies currently have well-established policies on how child-safe AI looks and sounds. That is understandable because people have only recently started using this technology on a large scale for free. “But now that they are, rather than having companies self-correct after children have been put at risk, child safety should inform the entire design cycle to lower the risk of dangerous incidents occurring.” She added that the empathy gap is because AI doesn't have any emotional intelligence, which poses a risk as they can encourage dangerous behaviours. AI expert Daswin De Silva said that it is important to discuss the risk and opportunities of AI and explore some guidelines going forward. “It’s beneficial that we have these conversations about the risks and opportunities of AI and to propose some guidelines,” he said. “We need to look at regulation. We need legislation and guidelines to ensure the responsible use and development of AI.” Image: Shutterstock
