"What a joke": Backlash over new strict speed limit

Melbourne residents have lashed out at a local council over the controversial decision to reduce the speed limit on bust roads. Every street in Fitzroy and Collingwood, except state-managed roads such as major thoroughfares, are now under the new strict speed limit of a mere 30 kilometres an hour, which has been enforced by the Yarra City Council. Thoroughfares that are currently exempt from the 30km/h limit include Johnston Street, Nicholson Street, Hoddle Street, Alexandra Parade and Victoria Parade, although the council is working hard to bring the speed limits on these major roads down to 40km/h or 60km/h. Yarra City Council Mayor, Edward Crossland, said there is clear evidence that reducing speed limits will lessen the number of road accidents and save lives. “We want to make our streets safer and better places for people of all ages and abilities whether you are walking, wheeling, cycling or driving. 30km can have a huge benefit and we know there is a lot of support for this initiative across our community,” he said. “Research shows that a person walking is at least twice as likely to be killed by a driver travelling at 40km than at 30km and that safer speed limits in urban areas has minimal impact on travel time." The council first began trialling the 30km/h speed limit in 2018 in northern parts of Fitzroy and Collingwood, and brought the number of crashes down by 52 percent over the first 12 months. Despite the evidence that reduced speeds help the community at large, not everyone is impressed by the change, with social media users claiming the lower speed limit will “never be enforced”. Another claimed, “When the police commissioner comes out and says it’s ridiculous and nobody will follow the limits then yeah, fair to say it won’t be enforced.” In 2023, Victorian Police chief commissioner Shane Patton, told ABC radio that changing the speed limit to 30km/h was “not the answer”. “I think no one’s going to obey it. It’s ridiculous,” he said. Social media users have branded the change an attempt at “revenue raising”, with one commenter saying: “Just another way to nab us with fines! All about the revenue.” “What a joke,” another person said, while one claimed people might as well start pushing their cars if the speed limit is so low. However, there are also those that have praised the council’s decision, branding it a “great initiative”. “Great news! More traffic calming please,” one person said. Image credits: Shutterstock

What is allyship? A brief history, present and future

<div class="theconversation-article-body"> <a href="https://theconversation.com/profiles/wendy-marie-cumming-potvin-542762">Wendy Marie Cumming-Potvin</a>, <a href="https://theconversation.com/institutions/murdoch-university-746">Murdoch University</a> Despite social change, LGBTQI+ people still face discrimination <a href="https://www.ohchr.org/en/statements/2019/10/inclusion-lgbt-people-education-settings-paramount-importance-leaving-no-one">at school</a> and <a href="https://www.tandfonline.com/doi/full/10.1080/10304312.2023.2296344">in the community</a>. Language for diverse genders and sexualities is continually changing. LGBTQI+ allyship is part of this change. But what is allyship? Allyship refers to people outside of a group – say, straight people – who actively support and work with people inside a group – say, LGBTQI+ people. It can also mean people from different groups working together to support each other’s goals. A key example of this was at the <a href="https://www.tandfonline.com/doi/full/10.1080/10304312.2023.2296344">Stonewall riots in 1969</a>, when lesbians, gay men and transgender people joined with Black Panthers and civil rights activists in New York City to protest against police brutality. But defining allyship can be challenging. Some people disagree about who an ally is. Others disagree about what an ally does. <h2>What is an ally?</h2> The term “ally” first appeared in US universities among students <a href="https://files.eric.ed.gov/fulltext/ED336682.pdf#page=215">in the early 1990s</a>. It was used to describe how majority group members (straight students) helped minorities (gay, lesbian and bisexual students), by advocating to end sexuality-based oppression in higher education. For many years, scholars have seen straight allyship for lesbian, gay and bisexual people as helpful for activism. Straight allies have played important roles in <a href="https://www.jstor.org/stable/j.ctt7pf5j">policy</a> and in <a href="https://www.tandfonline.com/doi/full/10.1080/19361653.2014.969867">combating prejudice</a> on high school and university campuses. Research has shown university and high school gay–straight alliances <a href="https://www.tandfonline.com/doi/full/10.1080/19361653.2017.1326867?casa_token=A6nQuWeFBIYAAAAA%3Ad-Tg1edyeiOyRDuHKyeHDcWuvqLLVhAFqyhXMjOe8RtWJH6pdwxUpES759QaY_zacNUS-TtqMXYK">have contributed</a> to more positive campus environments and a reduction in gender- and sexuality-based discrimination. Over many years, gay–straight teacher alliances have <a href="https://go.gale.com/ps/i.do?id=GALE%7CA227011983&sid=googleScholar&v=2.1&it=r&linkaccess=abs&issn=10813004&p=LitRC&sw=w&userGroupName=anon%7E40663b6e&aty=open-web-entry">successfully used</a> inquiry groups to combat homophobia and explore <a href="https://theconversation.com/explainer-what-does-intersectionality-mean-104937">intersectionality</a> (the way different facets of someone’s identity intersect) within their schools. These groups highlighted LGBTQI-themed literature in English class, and encouraged teachers to be outspoken in their support by attending community events, such as pride parades. But allyship can be exclusionary. While early perspectives of allyship focused on helping gay or lesbian university students, transgender or non-binary folk <a href="https://www.routledge.com/LGBTQI-Allies-in-Education-Advocacy-Activism-and-Participatory-Collaborative/Cumming-Potvin/p/book/9781032298832">were often ignored</a>. There is also contention about <a href="https://www.queensjournal.ca/justin-timberlakes-queer-allyship-strips-ally-of-its-meaning/">how much “work”</a> a straight ally has to do to earn recognition. Some people say that for someone to be called an ally they need to actively work for change, not just say they support others. As allies, we are continually learning. And sometimes we get it wrong. When we make mistakes, it’s important to apologise and continue supporting those we wish to serve. <h2>Allyship from within the community</h2> Many current definitions of allyship only encompass allies outside of the group they are supporting. But a broadened definition of allyship would be useful. LGBTQI+ people, especially with leadership roles, can be strong allies in their communities. Laverne Cox uses her stardom <a href="https://ccrjustice.org/home/blog/2019/08/02/evening-activism-laverne-cox">to advocate</a> for her community of transgender women of colour and other LGBTQI+ people. Georgie Stone made medical processes <a href="https://www.theguardian.com/society/2019/sep/07/it-takes-a-lot-of-courage-rebekah-robertson-on-raising-transgender-activist-georgie-stone">easier for transgender children</a> in Australia. <figure><iframe src="https://www.youtube.com/embed/-_dpLOXfOUE?wmode=transparent&start=0" width="440" height="260" frameborder="0" allowfullscreen="allowfullscreen"></iframe></figure> Because identities can shift, identifying who sits inside and outside LGBTQA+ communities can be challenging. Sometimes, there are clear social group insiders. Sometimes, there are clear outsiders. Other times, things are less clear. A person might hover inside and outside minority groups. They may not identify as straight, but they may not live publicly as LGBTQI+. Or a bisexual person may live in a straight relationship for many years. This means allyship is also dynamic. It <a href="https://www.suu.edu/pridealliance/pdf/reynolds.pdf">shifts</a> depending on power, privilege and life experiences. For example, in one social context, a white, heterosexual woman may have power as a LGBTQI+ ally. But in a professional setting where the majority of attendees are white heterosexual men, this same woman may not be as powerful. <h2>An intersectional process</h2> Allyship needs to understand that many people’s gender and sexuality interact with language fluency, class, geography, race, age and disability. This means that despite victories such as marriage equality, LGBTQI+ people who are homeless, transgender or people of colour may face <a href="https://theconversation.com/despite-recent-victories-plights-of-many-lgbt-people-remain-ignored-49273">significant barriers</a> in society. For example, as of May 2024, <a href="https://translegislation.com/">550 anti-trans bills</a> have been introduced in US legislatures. <a href="https://www.creativespirits.info/aboriginalculture/people/lgbti-aboriginal-people-diversity-at-the-margins">Because of</a> discrimination, racism and a silencing around Black queer history, LGBTQA+ Aboriginal and Torres Strait Islander people can receive inappropriate services, for example, <a href="https://journals.sagepub.com/doi/epdf/10.1177/10497323211069682">in healthcare and education</a>. Understanding the multiple identities of LGBTQI+ people will support strong allyship to reduce <a href="https://www.murdoch.edu.au/news/articles/national-survey-reveals-mental-health-burden-on-first-nations-lgbtqa-youth">negative health outcomes</a> for Aboriginal communities. <h2>What’s next for allyship?</h2> Recent Canadian work has grouped researchers, school boards and teacher federations to make <a href="https://trans-affirm.edu.uwo.ca/toolkit/Trans-Affirming%20Toolkit.pdf">ally resources</a> for supporting trans and gender-diverse students in Ontario. This tool kit includes modules for having conversations about gender identity and teaching about transgender policy. The final module introduces action plans for supporting transgender students through whole school approaches. History has shown coming together can lead to social transformation and better outcomes for marginalised groups. In 2016, US President Barack Obama designated the Stonewall Inn <a href="https://www.theguardian.com/world/2016/jun/24/obama-announces-stonewall-inn-national-monument">a national US monument</a> to celebrate gay history. Apart from acknowledging evolving ideas about gender and sexuality, future LGBTQI+ allyship needs to be intersectional. This means that factors like age, social class, geography, race, language and disability count. And when barriers are broken down across sectors, like healthcare, education and housing, allies become stronger.<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/220668/count.gif?distributor=republish-lightbox-basic" alt="The Conversation" width="1" height="1" /> <a href="https://theconversation.com/profiles/wendy-marie-cumming-potvin-542762">Wendy Marie Cumming-Potvin</a>, Associate Professor/ Director of Research (School of Education), <a href="https://theconversation.com/institutions/murdoch-university-746">Murdoch University</a> Image credits: Shutterstock This article is republished from <a href="https://theconversation.com">The Conversation</a> under a Creative Commons license.

"What goes around...": Colonial-era statue toppled

The statue honouring a controversial colonialist has been vandalised in Tasmania, with local councillors up in arms over the destruction. The statue paid tribute to William Crowther, a politician and surgeon who cut off and stole the skull of Aboriginal man William Lanne in 1869, with the intention of sending it to London's Royal College of Surgeons. On Wednesday morning, the statue was found face down after being sawn off at the ankles and falling from its plinth, with the words "what goes around" and "decolonize" spray-painted on the memorial. The toppling of the statue comes just hours after someone attempted to saw through the statue's ankles but stopped about two-thirds through. Hobart City Councillor Louise Elliot said she had noticed graffiti on the statue at midday on Tuesday and reported it, and then the cuts were found. When Councillor Elliot visited the statue at 8pm on Tuesday, she noted that "no security was here" after she stood at the site for "half an hour". She said she was "appalled" that a statue had been vandalised in a "completely foreseeable" incident. "I found out about this from Crowther's great-great granddaughter in tears ringing me," she said. "I'm really disappointed that the council, in my opinion, didn't take enough protective and preventive action to protect [the statue]." ast year, the council voted to remove the statue, which was appealed in the Tasmanian Tribunal of Civil and Administrative Tribunal on the basis its removal would detract from the site's heritage value. But in its decision, which was handed down today after the statue was toppled, the tribunal upheld the council's original decision to remove it. Deputy Premier Michael Ferguson said it was" regrettable" that someone thought to take the law into their own hands. <div data-component="EmphasisedText"> "Regardless of anybody's sentiment or feeling, good intentions or otherwise, that's not how we run a civil society," he said. </div> "Horrible things happened in our history, but you don't resolve history [through] vandalism." As members of Tasmania's indigenous community have been campaigning for years to have the statue removed, Tasmanian Aboriginal Centre (TAC) campaign manager Nala Mansell said the desecration of the statue reflected community attitudes. "I'm not endorsing what's happened but I think it goes to show that the people of Tasmania are people who understand right from wrong [and are] saying 'enough is enough.' "We've been fighting for decades for it to be gone," she said. <div data-component="EmphasisedText"> "Good on them for taking that action and doing what needed to be done a long time ago." </div> Image credits: Instagram - Kate Doyle ABC

It’s so hard to see a doctor right now. What are my options?

<div class="theconversation-article-body"> <a href="https://theconversation.com/profiles/anthony-scott-10738">Anthony Scott</a>, <a href="https://theconversation.com/institutions/monash-university-1065">Monash University</a> Deciding whether to wait and see if your health condition improves or go to a GP can be a difficult task. You might be unsure about where to go, whom to see, how much it will cost and whether you’ll need to take time off work. These choices can create significant barriers to accessing health care in Australia. There is often limited information available about the pros and cons of the different options. Often, we stick to what we know, unaware of better alternatives. But making the wrong decision about how to access care can impact both your health and finances. So what are your options? And what policy reforms are needed to improve affordable access to care for all Australians? <h2>How quickly can I be seen?</h2> Access depends on how long it takes you to speak to a GP, or be seen in an emergency department, or by a community pharmacist, or a nurse practitioner whom you can see directly. Access depends on where you live and the time of day. The rise of telehealth means GPs now get paid to talk to you on the phone, which is great for many minor ailments, medical certificates, repeat scripts or getting test results. Call centres such as <a href="https://www.healthdirect.gov.au/">Healthdirect</a> have been available for some time and now <a href="https://www.vved.org.au/patients/">virtual emergency departments</a> can also see you online. There are even GPs who only provide their services <a href="https://www.instantscripts.com.au/gp-online/">online</a> if you can pay. A phone call can save you valuable time. Before COVID, you needed to take half a day off work to see a GP, now it takes five to ten minutes and the GP even calls you. Things get more tricky outside of normal working hours and at weekends – appointments are harder to come by, it is unlikely you will be able to see a GP whom you know, and out-of-pocket costs might be higher. If you can’t wait, your local emergency department is likely to be more accessible, or you might be lucky enough to live near a bulk-billed Medicare <a href="https://www.health.gov.au/find-a-medicare-ucc">urgent care clinic</a>, where you don’t need an appointment. Tomorrow’s federal budget <a href="https://www.smh.com.au/politics/federal/more-free-urgent-care-clinics-part-of-8-5-billion-health-commitment-20240511-p5jcse.html">will include</a> funding for another 29 urgent care clinics, on top of the 58 already operating. But things are much worse if you live if a rural or remote area, where choice is limited and you need to wait much longer for GP appointments or travel long distances. Telehealth helps but can be expensive if it is not with your usual doctor. <h2>Who will I see?</h2> Access depends on who you will see. At the moment, this will usually be your GP (or, depending on the severity of your health concern, your community pharmacist or local emergency department staff). But to see your preferred GP you might need to wait as they are usually very busy. But a <a href="https://www.health.gov.au/resources/collections/issues-papers?language=en">review</a> of “scope of practice” in primary care aims to free up GPs’ time and use their skills more effectively. So in future, you could receive more of your health care from qualified nurses, nurse practitioners, pharmacists and other health professionals. But which tasks can be delegated to other health professionals is a significant bone of contention for GPs. For GP practices facing significant cost pressures, safely delegating tasks to other less costly health professionals also makes good business sense. <h2>How much will it cost?</h2> Access depends on out-of-pocket costs. Bulk billing of GP services reached a peak of <a href="https://www.health.gov.au/resources/publications/medicare-quarterly-statistics-state-and-territory-december-quarter-2023-24?language=en">89.6%</a> in the September quarter of 2022 but plummeted to 76.5% by the September quarter of 2023. Last November, bulk billing incentives for children under 16 and those on concession cards were tripled, and between November and December 2023 bulk billing had <a href="https://www.health.gov.au/ministers/the-hon-mark-butler-mp/media/bulk-billing-slide-stopped-thanks-to-albanese-government?language=en">increased</a> from 76.5% to 77.7%. They key issue for patients is that it remains uncertain whether a GP will bulk bill you. You often don’t know this until you get into the consultation, at which point you can’t back out. Unless the whole practice bulk bills and so it is guaranteed, it’s entirely up to the GP whether you are bulk billed. It’s difficult to think of any other service where you don’t know how much you will pay until after you have used it. <h2>How can policymakers improve access to care?</h2> Government policies to strengthen primary care have focused on giving patients improved access through telehealth, urgent care clinics and <a href="https://www.health.gov.au/resources/publications/strengthening-medicare-taskforce-report?language=en">Strengthening Medicare</a> initiatives, which are currently being developed. But uncertainty surrounding out-of-pocket costs can deter people from seeking medical attention, or delay care or go instead to the emergency department or urgent care clinic where there is no out-of-pocket cost. <a href="https://www.abs.gov.au/statistics/health/health-services/patient-experiences/latest-release">Cost is a factor</a> that leads to 20% of those with a mental health problem and 30% of those with chronic disease to delay or avoid visiting a health professional. Those most in need are more likely to miss out on necessary visits and prescriptions, sometimes with disastrous consequences. A recent <a href="https://academic.oup.com/qje/advance-article-abstract/doi/10.1093/qje/qjae015/7664375?login=false">study</a> shows people can die if they stop heart medications due to increased out-of-pocket costs. The next task for policymakers should be developing policies to guarantee there are no out-of-pocket costs for those on low incomes. This could be a worthwhile investment in our health and should be included in tomorrow’s budget.<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/229191/count.gif?distributor=republish-lightbox-basic" alt="The Conversation" width="1" height="1" /> <a href="https://theconversation.com/profiles/anthony-scott-10738">Anthony Scott</a>, Professor of Health Economics, <a href="https://theconversation.com/institutions/monash-university-1065">Monash University</a> Image credits: Shutterstock This article is republished from <a href="https://theconversation.com">The Conversation</a> under a Creative Commons license.

Too many Australians aren’t getting a flu vaccine. Why, and what can we do about it?

<div class="theconversation-article-body"> <a href="https://theconversation.com/profiles/holly-seale-94294">Holly Seale</a>, <a href="https://theconversation.com/institutions/unsw-sydney-1414">UNSW Sydney</a> Australia’s childhood immunisation program gets very good uptake every year – <a href="https://www.health.gov.au/topics/immunisation/immunisation-data/childhood-immunisation-coverage">almost 94% of five-year-olds</a> have had all their routine vaccinations. But our influenza vaccine coverage doesn’t get such a good report card. Looking back over <a href="https://ncirs.org.au/influenza-vaccination-coverage-data/historical-national-influenza-vaccination-coverage-end-year-age">recent years</a>, for kids aged six months to five years, we saw a peak in flu vaccine coverage at the beginning of the COVID pandemic at 46%, which then declined to 30% by the 2023 season. While we’re still relatively early in the 2024 flu season, only <a href="https://ncirs.org.au/influenza-vaccination-coverage-data">7% of children</a> under five have received their flu shot this year so far. Although young children are a particular concern, flu vaccination rates appear to be lagging for the population as a whole. Reports indicate that <a href="https://www.abc.net.au/news/2024-05-07/calls-to-vaccinate-young-children-against-flu-as-season-begins/103783508">from March 1 to April 28</a>, 16% fewer people were vaccinated against the flu compared with the same period last year. So what’s going on, and what can we do to boost uptake? <h2>Why do we vaccinate kids against the flu?</h2> Last year, <a href="https://www.health.gov.au/sites/default/files/2023-12/aisr-2023-national-influenza-season-summary.pdf">reported cases of flu</a> were highest in children aged five to nine, followed by those aged zero to four. This is not a new trend – we record a high number of flu cases and hospital admissions in kids every year. So far <a href="https://nindss.health.gov.au/pbi-dashboard/">this year</a> children aged zero to four have had the highest number of infections, marginally ahead of five- to nine-year-olds. While kids are more likely to catch and spread the flu, they’re also <a href="https://theconversation.com/kids-are-more-vulnerable-to-the-flu-heres-what-to-look-out-for-this-winter-117748">at greater risk</a> of getting very sick from it. This particularly applies to children under five, and the flu vaccine is available for free for this age group. The flu vaccine isn’t perfect – it may not prevent infections entirely – but it’s definitely our best chance of protection. Research has shown influenza-related visits to the GP were <a href="https://pubmed.ncbi.nlm.nih.gov/27577556/">more than halved</a> in vaccinated children compared with unvaccinated children. <h2>So why are kids not receiving the vaccine?</h2> Often, it comes down to misunderstandings about who is eligible for the vaccine or whom it’s recommended for. But we can address this issue by nudging people via <a href="https://www.annfammed.org/content/15/6/507?sf174332549=1">a text message reminder</a>. Some parents <a href="https://www.sciencedirect.com/science/article/pii/S0264410X17318285">report concerns</a> about the vaccine, including the old dogma that it can cause the flu. The flu vaccine <a href="https://www.betterhealth.vic.gov.au/health/healthyliving/flu-influenza-immunisation">can’t give you the flu</a> because it doesn’t contain live virus. Unfortunately, that myth is really sticky. For <a href="https://onlinelibrary.wiley.com/doi/full/10.1111/jpc.15235">some parents</a>, the challenge can be forgetting to book or accessing an appointment. <h2>It’s not just kids at higher risk</h2> Adults aged 65 and over are also <a href="https://theconversation.com/im-over-65-and-worried-about-the-flu-which-vaccine-should-i-have-204810">more vulnerable</a> to the flu, and can receive a <a href="https://www.health.gov.au/topics/immunisation/vaccines/influenza-flu-vaccine">free vaccine</a>. For this group, we usually get around <a href="https://ncirs.org.au/influenza-vaccination-coverage-data/historical-national-influenza-vaccination-coverage-end-year-age">65% vaccinated</a>. So far this year, <a href="https://ncirs.org.au/influenza-vaccination-coverage-data/national-influenza-vaccination-coverage-all-people-age-group">around 35%</a> of over-65s have received their flu vaccine. Aboriginal and Torres Strait Islander people are likewise eligible for a free flu vaccine. While previously coverage rates were higher among Aboriginal and Torres Strait Islander peoples compared to the overall population, this gap has narrowed. There’s even some movement backwards, especially <a href="https://ncirs.org.au/influenza-vaccination-coverage-data/historical-national-influenza-vaccination-coverage-end-year-age">in younger age groups</a>. The flu vaccine is also free for pregnant women and anyone who has <a href="https://www.health.gov.au/topics/immunisation/when-to-get-vaccinated/immunisation-for-people-with-medical-risk-conditions">a medical condition</a> such as heart disease, chronic lung disease, diabetes or kidney disease. Past studies have found flu vaccine coverage <a href="https://www.phrp.com.au/wp-content/uploads/2022/06/PHRP31232111.pdf">for pregnant women</a> varies around the country from 39% to 76% (meaning in some jurisdictions up to 60% of pregnant women are not getting vaccinated). When it comes to adults with chronic health conditions, we don’t have a good sense of how many people receive the vaccine. The reasons adults don’t always get the flu vaccine overlap with the reasons for children. Often <a href="https://www.tandfonline.com/doi/full/10.1080/08870446.2021.1957104">concerns about side effects</a> are cited as the reason for not getting vaccinated, followed by time constraints. We also know <a href="https://www.aihw.gov.au/reports/primary-health-care/coordination-of-health-care-experiences-barriers/summary">accessing medical services</a> can be difficult for some people, such as those living in rural areas or experiencing financial hardship. <h2>Filling the gaps</h2> In Australia, GPs offer flu vaccines for all ages, while flu vaccination is also available at pharmacies, generally from age five and up. While some people make a conscious decision not to get themselves or their children vaccinated, for many people, the barriers are related to access. Programs offering vaccination outside the doctor’s office are increasing globally, and may assist in <a href="https://www.tandfonline.com/doi/full/10.1080/14760584.2019.1698955">filling gaps</a>, especially among those who don’t have regular access to a GP. For some people, their only point of contact with the <a href="https://pubmed.ncbi.nlm.nih.gov/34272104/">medical system</a> may be during emergency department visits. Others may have more regular contact with a <a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC7046372/">specialist</a> who coordinates their medical care, rather than a GP. Offering vaccine education and programs <a href="https://journals.sagepub.com/doi/10.1177/0009922810374353">in these settings</a> has been shown to improve immunisation rates and may play a pivotal role in filling access gaps. Outside medical and pharmacy settings, the workplace is the most common place for Australian adults to receive their flu vaccine. A <a href="https://www.sciencedirect.com/science/article/pii/S1326020023004272">survey</a> showed Australian adults find workplace vaccination convenient and cost-effective, especially where free or subsidised vaccines are offered. Expanding vaccination settings, such as with <a href="https://journals.sagepub.com/doi/10.1177/19375867221087360?url_ver=Z39.88-2003&rfr_id=ori:rid:crossref.org&rfr_dat=cr_pub%20%200pubmed">drive-through</a> and mobile clinics, can benefit groups who have unique access barriers or are under-served. Meanwhile, offering vaccination through faith-based organisations has been shown to improve uptake among <a href="https://pubmed.ncbi.nlm.nih.gov/37013523/">racial and ethnic minority groups</a>.

Photos are everywhere. What makes a good one?

<div class="theconversation-article-body"><a href="https://theconversation.com/profiles/t-j-thomson-503845">T.J. Thomson</a>, <a href="https://theconversation.com/institutions/rmit-university-1063">RMIT University</a> We upload some <a href="https://theconversation.com/3-2-billion-images-and-720-000-hours-of-video-are-shared-online-daily-can-you-sort-real-from-fake-148630">3 billion images online each day</a>. We make <a href="https://www.tandfonline.com/doi/full/10.1080/1051144X.2023.2281163">most of these photos on smartphones</a> and use these devices to document everything from gym progress and our loved ones to a memorable meal. But what makes a “quality” photo? Many people, even those who make images for work, struggle to answer. They often say something along the lines of “I know it when I see it”. But knowing some dimensions of a quality photograph can help make your images stand out and make you a <a href="https://medialiteracy.org.au/media-literacy-framework/">more literate</a> media maker and consumer. Quality can be relative, but knowing the various dimensions at play can help you draw on those that are most relevant for your particular audience, context and purpose. I identified <a href="https://doi.org/10.1177/14648849241253136">six dimensions</a> which will impact the quality of photographs. Here’s what I learnt – and what you can apply to your own photographs. <h2>1. Production and presentation</h2> Think of the factors <a href="https://journals.sagepub.com/doi/full/10.1177/1522637918823261">in front of and behind the lens</a>. If you know you’re being recorded, this can affect your behaviour compared to a candid depiction. You might be more or less comfortable posing for a friend or family member than for a stranger. This comfort, or its lack, can lead to more stiff and awkward poses, or ones that look more natural and confident. Presentation circumstances, like the viewing size and context, also matter. A group shot can make a nice statement piece above a fireplace, but it wouldn’t have the same effect as a profile photo. Be aware of how “busy” your image is, and whether the viewing conditions are well-suited for the nature of your photo. Images with lots of elements, fine textures or other details need to be viewed large to be fully appreciated. Images with fewer, larger and simpler elements can usually be appreciated at smaller sizes. <h2>2. Technical aspects</h2> Technical aspects include proper exposure – meaning the image isn’t too dark or too bright – adequate focus, and appropriate camera settings. Some of these camera settings, like shutter speed, affect whether motion is seen as frozen or blurred. If the image is too blurry, too pixelated, or too light or dark, these technical aspects will negatively impact the photograph’s quality. But some motion blur, as distinct from camera shake, can make more dynamic an otherwise static composition. <h2>3. Who or what is shown</h2> Who or what is shown in the photographs we see is affected, in part, by access and novelty. That’s why we often make more photos during our holidays compared to documenting familiar settings. Some people or locations can be <a href="https://journals.sagepub.com/doi/full/10.1177/1329878X221094374">under-represented</a> and photographing them can lead to more visibility, and, depending on the context, a more empowering framing. Consider in your photography if you’re including people who are typically under-represented, such as older individuals, people of colour, people living with disabilities and queer people. Also consider whether you’re representing them in stereotypical or disempowering ways. As examples, <a href="https://www.tandfonline.com/doi/abs/10.1080/22041451.2022.2137237">when photographing older people</a>, consider whether you’re showing them as lonely, isolated, passive, or in need of mobility aids. <h2>4. Composition</h2> Composition includes positioning of elements in the frame, the balance between positive and negative space, and depth, among others. Generally, images that centre the subject of interest aren’t as visually engaging as images that offset the subject of interest. This is what’s known as the <a href="https://www.adobe.com/au/creativecloud/photography/discover/rule-of-thirds.html">rule-of-thirds</a> approach. Likewise, images that have no depth are generally not as interesting as images with a clear foreground, midground and background. “Seeing through things” with your compositions can help increase the visual depth of your photos alongside their visual appeal. <h2>5. The psycho-physiological</h2> The psycho-physiological concerns how the viewer reacts to what is shown. This includes the <a href="https://psycnet.apa.org/record/2011-07236-024">biological reaction</a> we have to seeing certain colours, for example the way the colour red can increase our heart rate. It also can include the feeling we have when seeing a photo of someone we know. The most powerful photos use colour and other elements of visual language strategically for a specific effect. Looking at these images might evoke a specific emotion, such as empathy or fear, and influence how the viewer responds. <h2>6. Narrative</h2> Narrative concerns the storytelling quality of the image. Images can show something in a literal way (think a photograph from a real estate listing) or they can tell a bigger story about the content represented or about the human condition (think about some of the iconic photos that emerged during Australia’s <a href="https://journals.sagepub.com/doi/abs/10.1177/1329878X211008181">black summer bushfire season</a>). Literal photos help us see what something or someone looks like but they might not have as much of an impact as iconic photos. For example, the well-known photo of three-year-old Syrian boy Aylan Kurdi’s lifeless body on a beach in Turkey <a href="https://www.reuters.com/article/idUSKBN14V2MG/">boosted fundraising for refugees</a> 100-fold. <h2>A more thoughtful process</h2> Next time you pull out your smartphone to make an image, don’t just “<a href="https://www.digitalphotomentor.com/do-you-wait-for-the-decisive-moment-or-do-you-spray-and-pray/">spray and pray</a>”. Try to pre-visualise the story you want to tell and wait for the elements to line up into place. Being aware of aesthetic and ethical considerations alongisde technical ones and emotional resonance can all help engage viewers and lead to more standout imagery. To challenge yourself further, consider taking your phone off full-auto mode and play with camera settings to see how they impact the resulting photos.<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/229011/count.gif?distributor=republish-lightbox-basic" alt="The Conversation" width="1" height="1" /> <a href="https://theconversation.com/profiles/t-j-thomson-503845">T.J.

Vitamins and supplements: what you need to know before taking them

<div class="theconversation-article-body"><a href="https://theconversation.com/profiles/neelaveni-padayachee-1018709">Neelaveni Padayachee</a>, <a href="https://theconversation.com/institutions/university-of-the-witwatersrand-894">University of the Witwatersrand</a> and <a href="https://theconversation.com/profiles/varsha-bangalee-1253468">Varsha Bangalee</a>, <a href="https://theconversation.com/institutions/university-of-kwazulu-natal-1941">University of KwaZulu-Natal</a> If you were to open your medicine cabinet right now, there’s a fair chance that you’d find at least one bottle of vitamins alongside the painkillers, plasters and cough syrup. After all, people are definitely buying vitamins: in 2020, the global market for complementary and alternative medicines, which includes multivitamin supplements, had an estimated value of <a href="https://www.grandviewresearch.com/industry-analysis/complementary-alternative-medicine-market">US$82.27 billion</a>. The use of natural health products such as minerals and amino acids has <a href="https://journals.lww.com/nutritiontodayonline/Abstract/2007/03000/Why_People_Use_Vitamin_and_Mineral_Supplements.4.aspx">increased</a> – and continues to rise, partly driven by consumers’ buying habits during the COVID-19 pandemic. People <a href="https://www.businesslive.co.za/bd/companies/healthcare/2021-02-08-native-sales-of-sas-vitamins-and-nutritional-supplements-boom/">sought out</a> vitamins C and D, as well as zinc supplements, as potential preventive measures against the virus – even though the <a href="https://www.health.harvard.edu/blog/do-vitamin-d-zinc-and-other-supplements-help-prevent-covid-19-or-hasten-healing-2021040522310">evidence</a> for their efficacy was, and <a href="https://pubmed.ncbi.nlm.nih.gov/35888660/#:%7E:text=Concluding%2C%20available%20data%20on%20the,trials%20(RCTs)%20are%20inconsistent">remains</a>, inconclusive. Multivitamins and mineral supplements are easily accessible to consumers. They are often marketed for their health claims and benefits – sometimes unsubstantiated. But their potential adverse effects are not always stated on the packaging. Collectively, vitamins and minerals are known as micronutrients. They are essential elements needed for our bodies to function properly. Our bodies can only produce micronutrients in small amounts or not at all. We get the bulk of these nutrients <a href="https://www.iprjb.org/journals/index.php/IJF/article/view/1024">from our diets</a>. People usually buy micronutrients to protect against disease or as dietary “insurance”, in case they are not getting sufficient quantities from their diets. There’s a common perception that these supplements are harmless. But they can be dangerous at incorrect dosages. They provide a false sense of hope, pose a risk of drug interactions – and can delay more effective treatment. <h2>Benefits</h2> Vitamins are beneficial if taken for the correct reasons and as prescribed by your doctor. For example, folic acid supplementation in pregnant women has been shown to prevent neural tube defects. And individuals who reduce their intake of red meat without increasing legume consumption require a vitamin B6 supplement. But a worrying trend is increasing among consumers: intravenous vitamin therapy, which is often punted by celebrities and social media marketing. Intravenous vitamins, nutrients and fluids are administered at pharmacies as well as beauty spas, and more recently “<a href="https://www.health.harvard.edu/blog/drip-bar-should-you-get-an-iv-on-demand-2018092814899">IV bars</a>”. Users believe these treatments can quell a cold, slow the effects of ageing, brighten skin, fix a hangover or just make them feel well. Intravenous vitamin therapy was previously only used in medical settings to help patients who could not swallow, needed fluid replacements or had an electrolyte imbalance. However, the evidence to support other benefits of intravenous vitamin therapy is limited. No matter how you choose to get additional vitamins, there are risks. <h2>Warning bells</h2> Most consumers use multivitamins. But others take large doses of single nutrients, especially vitamin C, iron and calcium. As lecturers in pharmacy practice, we think it’s important to highlight the potential adverse effects of commonly used vitamins and minerals: <ul> <li> <a href="https://www.hsph.harvard.edu/nutritionsource/vitamin-a/">Vitamin A/retinol</a> is beneficial in maintaining good eye health. But it can cause toxicity if more than 300,000IU (units) is ingested. Chronic toxicity (hypervitaminosis) has been <a href="https://www.ncbi.nlm.nih.gov/books/NBK532916/">associated</a> with doses higher than 10,000IU a day. Symptoms include liver impairment, loss of vision and intracranial hypertension. It can cause birth defects in pregnant women. </li> <li> <a href="https://www.hsph.harvard.edu/nutritionsource/niacin-vitamin-b3/">Vitamin B3</a> is beneficial for nervous and digestive system health. At moderate to high doses it can cause peripheral vasodilation (widening or dilating of the blood vessels at the extremities, such as the legs and arms), resulting in skin flushing, burning sensation, pruritis (itchiness of the skin) and hypotension (low blood pressure). </li> <li> <a href="https://www.hsph.harvard.edu/nutritionsource/vitamin-b6/">Vitamin B6</a> is essential for brain development and in ensuring that the immune system remains healthy. But it can result in damage to the peripheral nerves, such as those in the hands and feet (causing a sensation of numbness and often referred to as pins and needles) at doses over 200mg/daily. </li> <li> <a href="https://www.hsph.harvard.edu/nutritionsource/vitamin-c/">Vitamin C</a> is an antioxidant and assists in the repair of body tissue. Taken in high doses it can cause kidney stones and interactions with drugs, such as the oncology drugs doxorubicin, methotrexate, cisplatin and vincristine. </li> <li> <a href="https://www.hsph.harvard.edu/nutritionsource/vitamin-d/">Vitamin D</a> is essential for bone and teeth development. At high doses it can cause hypercalcaemia (calcium level in the blood is above normal) that results in thirst, excessive urination, seizures, coma and death. </li> <li> <a href="https://www.hsph.harvard.edu/nutritionsource/calcium/#:%7E:text=Calcium%20is%20a%20mineral%20most,heart%20rhythms%20and%20nerve%20functions">Calcium</a> is essential for bone health, but can cause constipation and gastric reflux. High doses can cause hypercalciuria (increased calcium in the urine), kidney stones and secondary hypoparathyroidism (underactive parathyroid gland). It can have drug interactions with zinc, magnesium and iron. </li> <li> <a href="https://www.hsph.harvard.edu/nutritionsource/magnesium/">Magnesium</a> is important for muscle and nerve functioning. At high doses it can cause diarrhoea, nausea and abdominal cramping, and can interact with tetracyclines (antibiotics). </li> <li> Zinc <a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC7781367/">can impair</a> taste and smell, and doses over 80mg daily have been <a href="https://link.springer.com/article/10.1007/s10654-022-00922-0#:%7E:text=Zinc%20supplementation%20of%20more%20than,zinc%20supplements%20among%20adult%20men.">shown</a> to have adverse prostate effects. </li> <li> <a href="https://www.hsph.harvard.edu/nutritionsource/selenium/">Selenium</a> can cause hair and nail loss or brittleness, lesions of the skin and nervous system, skin rashes, fatigue and mood irritability at high doses. </li> <li> <a href="https://www.sciencedirect.com/science/article/pii/S0098299720300364#:%7E:text=Expert%20guidelines%20for%20oral%20iron%20supplementation&text=Traditionally%2C%20the%20recommended%20daily%20dose,iron%20(Brittenham%2C%202018).">Iron</a> at 100-200mg/day can cause constipation, black faeces, black discoloration of teeth and abdominal pain. </li> </ul> <h2>Recommendations</h2> People need to make <a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC8377299/">informed decisions</a> based on evidence before consuming health products. Regular exercise and a well-balanced diet are more likely to do us good, as well as being lighter on the pocket. Seeking advice from a healthcare professional before consuming supplements can reduce the risk of adverse effects. Be aware of the potential adverse effects of vitamins and seek a healthcare professional’s guidance if you have symptoms.<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/198345/count.gif?distributor=republish-lightbox-basic" alt="The Conversation" width="1" height="1" /> <a href="https://theconversation.com/profiles/neelaveni-padayachee-1018709">Neelaveni Padayachee</a>, Senior Lecturer, Department of Pharmacy and Pharmacology, <a href="https://theconversation.com/institutions/university-of-the-witwatersrand-894">University of the Witwatersrand</a> and <a href="https://theconversation.com/profiles/varsha-bangalee-1253468">Varsha Bangalee</a>, Associate Professor, Pharmaceutical Sciences, <a href="https://theconversation.com/institutions/university-of-kwazulu-natal-1941">University of KwaZulu-Natal</a> Image credits: Getty Images This article is republished from <a href="https://theconversation.com">The Conversation</a> under a Creative Commons license.

Body

What are heart rate zones, and how can you incorporate them into your exercise routine?

<div class="theconversation-article-body"><a href="https://theconversation.com/profiles/hunter-bennett-1053061">Hunter Bennett</a>, <a href="https://theconversation.com/institutions/university-of-south-australia-1180">University of South Australia</a> If you spend a lot of time exploring fitness content online, you might have come across the concept of heart rate zones. Heart rate zone training has become more popular in recent years partly because of the boom in wearable technology which, among other functions, allows people to easily track their heart rates. <a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC6537749/">Heart rate zones</a> reflect different levels of intensity during aerobic exercise. They’re most often based on a percentage of your maximum heart rate, which is the highest number of beats your heart can achieve per minute. But what are the different heart rate zones, and how can you use these zones to optimise your workout? <h2>The three-zone model</h2> While there are several models used to describe heart rate zones, the most common model in the scientific literature is the <a href="https://journals.humankinetics.com/view/journals/ijspp/9/1/article-p100.xml">three-zone model</a>, where the zones may be categorised as follows: <ul> <li> zone 1: 55%–82% of maximum heart rate </li> <li> zone 2: 82%–87% of maximum heart rate </li> <li> zone 3: 87%–97% of maximum heart rate. </li> </ul> If you’re not sure what your maximum heart rate is, it can be calculated using <a href="https://www.jacc.org/doi/full/10.1016/S0735-1097%2800%2901054-8">this equation</a>: 208 – (0.7 × age in years). For example, I’m 32 years old. 208 – (0.7 x 32) = 185.6, so my predicted maximum heart rate is around 186 beats per minute. There are also other models used to describe heart rate zones, such as the <a href="https://journals.humankinetics.com/view/journals/ijspp/14/8/article-p1151.xml">five-zone model</a> (as its name implies, this one has five distinct zones). These <a href="https://journals.humankinetics.com/view/journals/ijspp/9/1/article-p100.xml">models</a> largely describe the same thing and can mostly be used interchangeably. <h2>What do the different zones involve?</h2> The three zones are based around a person’s <a href="https://link.springer.com/article/10.2165/00007256-200939060-00003">lactate threshold</a>, which describes the point at which exercise intensity moves from being predominantly aerobic, to predominantly anaerobic. Aerobic exercise <a href="https://www.healthline.com/health/fitness-exercise/difference-between-aerobic-and-anaerobic">uses oxygen</a> to help our muscles keep going, ensuring we can continue for a long time without fatiguing. Anaerobic exercise, however, uses stored energy to fuel exercise. Anaerobic exercise also accrues metabolic byproducts (such as lactate) that increase fatigue, meaning we can only produce energy anaerobically for a short time. On average your lactate threshold tends to sit around <a href="https://www.tandfonline.com/doi/full/10.2147/OAJSM.S141657">85% of your maximum heart rate</a>, although this varies from person to person, and can be <a href="https://journals.physiology.org/doi/full/10.1152/japplphysiol.00043.2013">higher in athletes</a>. In the three-zone model, each zone loosely describes <a href="https://www.frontiersin.org/journals/physiology/articles/10.3389/fphys.2015.00295/full">one of three types of training</a>. Zone 1 represents high-volume, low-intensity exercise, usually performed for long periods and at an easy pace, well below lactate threshold. Examples include jogging or cycling at a gentle pace. Zone 2 is threshold training, also known as tempo training, a moderate intensity training method performed for moderate durations, at (or around) lactate threshold. This could be running, rowing or cycling at a speed where it’s difficult to speak full sentences. Zone 3 mostly describes methods of high-intensity interval training, which are performed for shorter durations and at intensities above lactate threshold. For example, any circuit style workout that has you exercising hard for 30 seconds then resting for 30 seconds would be zone 3. <h2>Striking a balance</h2> To maximise endurance performance, you need to strike a balance between doing enough training to elicit positive changes, while avoiding over-training, injury and burnout. While zone 3 is thought to produce the largest improvements in <a href="https://www.sciencedirect.com/science/article/pii/S1440244018309198">maximal oxygen uptake</a> – one of the best predictors of endurance performance and overall health – it’s also the most tiring. This means you can only perform so much of it before it becomes too much. Training in different heart rate zones improves <a href="https://citeseerx.ist.psu.edu/document?repid=rep1&type=pdf&doi=38c07018c0636422d9d5a77316216efb3c10164f">slightly different physiological qualities</a>, and so by spending time in each zone, you ensure a <a href="https://link.springer.com/article/10.1007/bf00426304">variety of benefits</a> for performance and health. <h2>So how much time should you spend in each zone?</h2> Most <a href="https://www.frontiersin.org/articles/10.3389/fspor.2023.1258585/full">elite endurance athletes</a>, including runners, rowers, and even cross-country skiers, tend to spend most of their training (around 80%) in zone 1, with the rest split between zones 2 and 3. Because elite endurance athletes train a lot, most of it needs to be in zone 1, otherwise they risk injury and burnout. For example, some runners accumulate <a href="https://journals.humankinetics.com/view/journals/ijsnem/22/5/article-p392.xml?content=pdf">more than 250 kilometres per week</a>, which would be impossible to recover from if it was all performed in zone 2 or 3. Of course, most people are not professional athletes. The <a href="https://www.who.int/news-room/fact-sheets/detail/physical-activity">World Health Organization</a> recommends adults aim for 150–300 minutes of moderate intensity exercise per week, or 75–150 minutes of vigorous exercise per week. If you look at this in the context of heart rate zones, you could consider zone 1 training as moderate intensity, and zones 2 and 3 as vigorous. Then, you can use heart rate zones to make sure you’re exercising to meet these guidelines. <h2>What if I don’t have a heart rate monitor?</h2> If you don’t have access to a heart rate tracker, that doesn’t mean you can’t use heart rate zones to guide your training. The three heart rate zones discussed in this article can also be prescribed based on feel using a simple <a href="https://onlinelibrary.wiley.com/doi/10.1111/j.1600-0838.2004.00418.x">10-point scale</a>, where 0 indicates no effort, and 10 indicates the maximum amount of effort you can produce. With this system, zone 1 aligns with a 4 or less out of 10, zone 2 with 4.5 to 6.5 out of 10, and zone 3 as a 7 or higher out of 10. Heart rate zones are not a perfect measure of exercise intensity, but can be a useful tool. And if you don’t want to worry about heart rate zones at all, that’s also fine. The most important thing is to simply get moving.<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/228520/count.gif?distributor=republish-lightbox-basic" alt="The Conversation" width="1" height="1" /> <a href="https://theconversation.com/profiles/hunter-bennett-1053061">Hunter Bennett</a>, Lecturer in Exercise Science, <a href="https://theconversation.com/institutions/university-of-south-australia-1180">University of South Australia</a> Image credits: Getty Images This article is republished from <a href="https://theconversation.com">The Conversation</a> under a Creative Commons license.

What is childhood dementia? And how could new research help?

<div class="theconversation-article-body"> <a href="https://theconversation.com/profiles/kim-hemsley-1529322">Kim Hemsley</a>, <a href="https://theconversation.com/institutions/flinders-university-972">Flinders University</a>; <a href="https://theconversation.com/profiles/nicholas-smith-1529324">Nicholas Smith</a>, <a href="https://theconversation.com/institutions/university-of-adelaide-1119">University of Adelaide</a>, and <a href="https://theconversation.com/profiles/siti-mubarokah-1529323">Siti Mubarokah</a>, <a href="https://theconversation.com/institutions/flinders-university-972">Flinders University</a> “Childhood” and “dementia” are two words we wish we didn’t have to use together. But sadly, around <a href="https://doi.org/10.1093/brain/awad242">1,400 Australian children and young people</a> live with currently untreatable childhood dementia. Broadly speaking, childhood dementia is caused by any one of <a href="https://www.childhooddementia.org/what-is-childhood-dementia#what">more than 100</a> rare genetic disorders. Although the causes differ from dementia acquired later in life, the progressive nature of the illness is the same. <a href="https://doi.org/10.1093/brain/awad242">Half</a> of infants and children diagnosed with childhood dementia will not reach their tenth birthday, and most will die <a href="https://www.childhooddementia.org/what-is-childhood-dementia#what">before turning 18</a>. Yet this devastating condition has lacked awareness, and importantly, the research attention needed to work towards treatments and a cure. <h2>More about the causes</h2> Most types of childhood dementia are <a href="https://academic.oup.com/brain/article/146/11/4446/7226999">caused</a> by <a href="https://www.genome.gov/genetics-glossary/Mutation">mutations</a> (or mistakes) in our <a href="https://www.genome.gov/genetics-glossary/Deoxyribonucleic-Acid">DNA</a>. These mistakes lead to a range of rare genetic disorders, which in turn cause childhood dementia. <a href="https://doi.org/10.1093/brain/awad242">Two-thirds</a> of childhood dementia disorders are caused by “<a href="https://www.ncbi.nlm.nih.gov/books/NBK459183/">inborn errors of metabolism</a>”. This means the metabolic pathways involved in the breakdown of carbohydrates, lipids, fatty acids and proteins in the body fail. As a result, nerve pathways fail to function, neurons (nerve cells that send messages around the body) die, and progressive cognitive decline occurs. <h2>What happens to children with childhood dementia?</h2> Most children initially appear unaffected. But after a period of apparently normal development, children with childhood dementia <a href="https://doi.org/10.1016/j.pediatrneurol.2023.09.006">progressively lose</a> all previously acquired skills and abilities, such as talking, walking, learning, remembering and reasoning. Childhood dementia also leads to significant changes in behaviour, such as aggression and hyperactivity. Severe sleep disturbance is common and vision and hearing can also be affected. Many children have seizures. The age when symptoms start can vary, depending partly on the particular genetic disorder causing the dementia, but the average is around <a href="https://doi.org/10.1093%2Fbrain%2Fawad242">two years old</a>. The symptoms are caused by significant, progressive brain damage. <h2>Are there any treatments available?</h2> Childhood dementia treatments currently <a href="https://www.childhooddementia.org/news/report-reveals-global-research-inequity">under evaluation</a> or approved are for a very limited number of disorders, and are only available in some parts of the world. These include gene replacement, <a href="https://doi.org/10.1002/jmd2.12378">gene-modified cell therapy</a> and protein or <a href="https://www.nejm.org/doi/full/10.1056/NEJMoa1712649">enzyme replacement therapy</a>. Enzyme replacement therapy is available in Australia for <a href="https://australianprescriber.tg.org.au/articles/cerliponase-alfa-for-neuronal-ceroid-lipofuscinosis-type-2-disease.html">one form of childhood dementia</a>. These therapies attempt to “fix” the problems causing the disease, and have shown promising results. Other experimental therapies include ones that <a href="https://doi.org/10.3390/life12050608">target</a> faulty protein production or <a href="https://doi.org/10.1056/nejmoa2310151">reduce inflammation</a> in the brain. <h2>Research attention is lacking</h2> Death rates for Australian children with cancer <a href="http://www.childhooddementia.org/getasset/2WX39O">nearly halved</a> between <a href="https://www.aihw.gov.au/reports/children-youth/australias-children/contents/health/cancer-incidence-survival">1997 and 2017</a> thanks to research that has enabled the development of multiple treatments. But over recent decades, <a href="http://www.childhooddementia.org/getasset/2WX39O">nothing has changed</a> for children with dementia. In 2017–2023, research for childhood cancer received over four times more funding per patient compared to funding for <a href="https://www.childhooddementia.org/getasset/2WX39O">childhood dementia</a>. This is despite childhood dementia causing a <a href="https://doi.org/10.1093/brain/awad242">similar number of deaths</a> each year as childhood cancer. The success <a href="https://www.aihw.gov.au/reports/children-youth/australias-children/contents/health/cancer-incidence-survival">for childhood cancer sufferers</a> in recent decades demonstrates how adequately funding medical research can lead to improvements in patient outcomes. Another bottleneck for childhood dementia patients in Australia is the lack of access to clinical trials. An <a href="https://www.childhooddementia.org/news/report-reveals-global-research-inequity">analysis</a> published in March this year showed that in December 2023, only two clinical trials were recruiting patients with childhood dementia in Australia. Worldwide however, 54 trials were recruiting, meaning Australian patients and their families are left watching patients in other parts of the world receive potentially lifesaving treatments, with no recourse themselves. That said, we’ve seen a slowing in the establishment of <a href="https://www.childhooddementia.org/news/report-reveals-global-research-inequity">clinical trials</a> for childhood dementia across the world in recent years. In addition, we know from <a href="https://www.childhooddementia.org/join-us/professionals/impacts">consultation with families</a> that current care and support systems <a href="https://www.childhooddementia.org/getasset/44MLP8">are not meeting the needs</a> of children with dementia and their families. <h2>New research</h2> Recently, we were awarded <a href="https://www.premier.sa.gov.au/media-releases/news-items/major-funding-boost-for-research-into-childhood-dementia">new funding</a> for <a href="https://www.flinders.edu.au/giving/our-donors/impact-of-giving/improving-the-lives-of-children-with-dementia">our research</a> on childhood dementia. This will help us continue and expand studies that seek to develop lifesaving treatments. More broadly, we need to see increased funding in Australia and around the world for research to develop and translate treatments for the broad spectrum of childhood dementia conditions.

What just happened to Bonza? Why new budget airlines always struggle in Australia

<div class="theconversation-article-body"> <a href="https://theconversation.com/profiles/ian-douglas-2932">Ian Douglas</a>, <a href="https://theconversation.com/institutions/unsw-sydney-1414">UNSW Sydney</a> and <a href="https://theconversation.com/profiles/seena-sarram-1469656">Seena Sarram</a>, <a href="https://theconversation.com/institutions/unsw-sydney-1414">UNSW Sydney</a> The history of budget jet airlines in Australia is a long road <a href="https://www.smh.com.au/traveller/travel-news/grounded-five-of-australias-biggest-airline-failures-20221216-h28pzn.html">littered with broken dreams</a>. New entrants have consistently struggled to get a foothold. Low-cost carrier Bonza has just become the industry’s <a href="https://www.afr.com/companies/transport/bonza-flights-cancelled-as-aircraft-repossessed-20240430-p5fnjf">latest casualty</a>, entering voluntary administration on Tuesday after abruptly cancelling all flights. Losing the airline would be heartbreaking for the 24 regional Australian locations that were <a href="https://www.accc.gov.au/system/files/domestic-airline-competition-report-february2024_0.pdf">not connected directly</a> by any other airline. It would also mean even less competition in a heavily concentrated domestic air travel market. Over 85% of routes are operated by just <a href="https://www.accc.gov.au/system/files/domestic-airline-competition-report-february2024_0.pdf">three airline groups</a>. But Bonza hasn’t just fallen into this situation by chance. Strategic missteps likely played a key role from the very beginning. <h2>What went wrong</h2> First, running an airline is an expensive business – any cost savings airlines can find are extremely valuable. Bonza chose to enter the Australian market with a very small fleet of <a href="https://skybrary.aero/aircraft-family/b737-series">Boeing B737</a> jet aircraft. But these had no operating cost advantage over the B737s already flown by Qantas, Virgin and Rex. Bonza’s small fleet also lacked any scale advantage in scheduling aircraft or crew. Second, to sell tickets, Bonza adopted a radically different “<a href="https://flybonza.com/media/bonza-gets-wheels-up#:%7E:text=Bonza%20is%20the%20first%20airline,uniform%20including%20custom%20Bonza%20sneakers.">app first</a>” approach. The only place customers could search for and book tickets directly was the official Bonza app. But this meant potential customers using conventional search tools – such as search engines or booking websites – often couldn’t find Bonza flights. The fact Bonza <a href="https://www.couriermail.com.au/business/qld-business/gold-coast-airport-sweetheart-deals-raise-concern-for-bonza/news-story/5ecdfe749b7c8a636cfe740ee0359ba3">struggled</a> to gain traction on its routes to Gold Coast airport, which handles a sizeable 250,000 domestic passengers each month, underscores this issue with the company’s approach. And third, although it served a unique range of locations, Bonza’s flight schedule across its network was far from optimal. In some cases, routes were flown only once weekly, compared to much more frequent gateway city services on Rex and QantasLink. For European airlines like easyJet or Ryanair, less-than-daily flights to smaller tourist destinations might be viable. But these airlines have the scale and connectivity to offer customers alternative pathways across their networks. Unlike Bonza, small regional routes are not at the core of their business model. <h2>Making an airline succeed</h2> Bonza isn’t the first Australian budget carrier to fail, and likely won’t be the last. Why are so many new entrants doomed to fail? Making a jet airline succeed hinges on optimising three key factors – market scale, airport access, and geography. For would-be budget airlines, Australia offers a brutal starting ground on all three. Market scale <a href="https://www.icao.int/sustainability/Pages/Low-Cost-Carriers.aspx">Low-cost carrier</a> and ultra low-cost carrier airlines have successfully gained strong footholds in Europe, the US, and Southeast Asia. But these markets are orders of magnitude larger than Australia. The US, for example, offers airlines a market of <a href="https://www.statista.com/statistics/183600/population-of-metropolitan-areas-in-the-us/">large cities across a large area</a>. New York’s population is approaching 20 million, Chicago 9.6 million, Houston 7.1 million, and Miami 6.1 million. The population of the European Union is close to 450 million. And if you include the UK, there are over 30 cities in Europe with populations over 1 million. Australian carriers have only a handful of cities on that scale. Australia lacks both the population density of Europe, and the range of secondary airports that European low-cost carriers have leveraged to access nearby markets and to drive down operating costs. After more than a year of operation, Bonza had only achieved an overall market share of <a href="https://www.accc.gov.au/system/files/domestic-airline-competition-report-february2024_0.pdf">about 2%</a>. Airport access Airport access is the next key barrier facing low-cost and ultra low-cost market entrants. The main routes between large Australian cities are all in a corridor along the east coast, and the largest flow into Sydney. Use of Sydney airport is heavily constrained, both by the incumbent operators who <a href="https://australianaviation.com.au/2023/07/sydney-slot-system-a-threat-to-bonza-owner-hints/">hold most of the slots</a>, and by regulations that artificially limit the flow of aircraft at peak times to just 80 movements (take-offs or landings) per hour. In contrast, London Heathrow, another constrained two-runway airport, delivers a capacity of <a href="https://www.caa.co.uk/media/dwfgyk53/estimating-the-congestion-premium-at-heathrow.pdf">88 movements per hour</a>. Completion of the new Western Sydney Airport will provide some relief from this capacity constraint. But it will not alter the fact Sydney Airport operates under an imposed constraint on operations. Geography Geography is the third constraint in Australia. Unlike Europe, the US, or Southeast Asia, most of our major cities are in a line on the east coast. There is no hub to connect our major cities with smaller regional points. Towns that are too distant for convenient rail or road links often have populations that are too small to support viable – let alone frequent – flights to the larger centres. Some regional routes are successfully serviced by small “<a href="https://nbaa.org/business-aviation/business-aircraft/turboprop-aircraft/">turboprop</a>” aircraft. Operating these incurs a higher cost per passenger than the passenger jets connecting the major cities. But it makes no sense to fly larger aircraft on these routes if the planes are half empty. <h2>A big loss for regional Australia</h2> The combination of Australia’s small population, the capacity constraints imposed on Sydney Airport, the presence of strong incumbent airlines, and our linear east coast market make new entry difficult. Virgin Blue occupied the space created by the collapse of Ansett. But Impulse, Tiger, Air Australia, Ozjet, and two versions of Compass were unsuccessful market entrants. Even Air New Zealand – which has the fleet, brand strength, and market access to support entering the market – chooses not to operate domestically in Australia. Understanding why new entrants fail offers little consolation to underserved regional towns in Australia. But given Bonza’s small footprint, capital city travellers looking for more competition on the major east coast routes will hardly notice a change.<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/228995/count.gif?distributor=republish-lightbox-basic" alt="The Conversation" width="1" height="1" /> <a href="https://theconversation.com/profiles/ian-douglas-2932">Ian Douglas</a>, Honorary Senior Lecturer, UNSW Aviation., <a href="https://theconversation.com/institutions/unsw-sydney-1414">UNSW Sydney</a> and <a href="https://theconversation.com/profiles/seena-sarram-1469656">Seena Sarram</a>, Lawyer and Casual Academic, UNSW School of Aviation, <a href="https://theconversation.com/institutions/unsw-sydney-1414">UNSW Sydney</a> Image credits: Bonza - PR Image This article is republished from <a href="https://theconversation.com">The Conversation</a> under a Creative Commons license.

What’s the difference between ADD and ADHD?

<div class="theconversation-article-body"> <a href="https://theconversation.com/profiles/kathy-gibbs-1392051">Kathy Gibbs</a>, <a href="https://theconversation.com/institutions/griffith-university-828">Griffith University</a> Around <a href="https://www.healthdirect.gov.au/attention-deficit-disorder-add-or-adhd#:%7E:text=Around%201%20in%20every%2020,have%20symptoms%20as%20an%20adult.">one in 20 people</a> has attention-deficit hyperactivity disorder (ADHD). It’s one of the most common neurodevelopmental disorders in childhood and often continues into adulthood. ADHD is <a href="https://www.psychiatry.org/psychiatrists/practice/dsm">diagnosed</a> when people experience problems with inattention and/or hyperactivity and impulsivity that negatively impacts them at school or work, in social settings and at home. Some people call the condition attention-deficit disorder, or ADD. So what’s the difference? In short, what was previously called ADD is now known as ADHD. So how did we get here? <h2>Let’s start with some history</h2> The <a href="https://www.guilford.com/books/Attention-Deficit-Hyperactivity-Disorder/Russell-Barkley/9781462538874">first clinical description</a> of children with inattention, hyperactivity and impulsivity was in 1902. British paediatrician Professor George Still <a href="https://pubmed.ncbi.nlm.nih.gov/26740929/">presented</a> a series of lectures about his observations of 43 children who were defiant, aggressive, undisciplined and extremely emotional or passionate. Since then, our understanding of the condition evolved and made its way into the Diagnostic and Statistical Manual of Mental Disorders, known as the DSM. Clinicians use the DSM to diagnose mental health and neurodevelopmental conditions. The first DSM, published in 1952, did not include a specific related child or adolescent category. But the <a href="https://dsm.psychiatryonline.org/doi/abs/10.1176/appi.books.9780890420355.dsm-ii">second edition</a>, published in 1968, <a href="https://www.tandfonline.com/doi/full/10.1080/00207411.2015.1009310">included a section</a> on behaviour disorders in young people. It referred to ADHD-type characteristics as “hyperkinetic reaction of childhood or adolescence”. This described the excessive, involuntary movement of children with the disorder. In the early 1980s, the <a href="https://www.psychiatry.org/psychiatrists/practice/dsm/about-dsm/history-of-the-dsm">third DSM</a> added a condition it called “attention deficit disorder”, listing two types: attention deficit disorder with hyperactivity (ADDH) and attention deficit disorder as the subtype without the hyperactivity. However, seven years later, a revised DSM (DSM-III-R) replaced ADD (and its two sub-types) with ADHD and three sub-types we have today: <ul> <li>predominantly inattentive</li> <li>predominantly hyperactive-impulsive</li> <li>combined.</li> </ul> <h2>Why change ADD to ADHD?</h2> ADHD replaced ADD in the DSM-III-R in 1987 for a number of reasons. First was the controversy and debate over the presence or absence of hyperactivity: the “H” in ADHD. When ADD was <a href="https://www.guilford.com/books/Attention-Deficit-Hyperactivity-Disorder/Russell-Barkley/9781462538874">initially named</a>, little research had been done to determine the similarities and differences between the two sub-types. The next issue was around the term “attention-deficit” and whether these deficits were similar or different across both sub-types. Questions also arose about the extent of these differences: if these sub-types were so different, were they actually different conditions? Meanwhile, a new focus on inattention (an “attention deficit”) recognised that children with inattentive behaviours <a href="https://academic.oup.com/shm/article/30/4/767/2919401">may not necessarily be</a> disruptive and challenging but are more likely to be forgetful and daydreamers. <h2>Why do some people use the term ADD?</h2> There was a <a href="https://academic.oup.com/shm/article/30/4/767/2919401">surge of diagnoses</a> in the 1980s. So it’s understandable that some people still hold onto the term ADD. Some may identify as having ADD because out of habit, because this is what they were originally diagnosed with or because they don’t have hyperactivity/impulsivity traits. Others who don’t have ADHD may use the term they came across in the 80s or 90s, not knowing the terminology has changed. <h2>How is ADHD currently diagnosed?</h2> The three sub-types of ADHD, outlined in the DSM-5 are: <ul> <li> predominantly inattentive. People with the inattentive sub-type have difficulty sustaining concentration, are easily distracted and forgetful, lose things frequently, and are unable to follow detailed instructions </li> <li> predominantly hyperactive-impulsive. Those with this sub-type find it hard to be still, need to move constantly in structured situations, frequently interrupt others, talk non-stop and struggle with self control </li> <li> combined. Those with the combined sub-type experience the characteristics of those who are inattentive and hyperactive-impulsive. </li> </ul> ADHD diagnoses <a href="https://www.aihw.gov.au/reports/children-youth/australias-children/contents/health/children-mental-illness">continue to rise</a> among children and adults. And while ADHD was commonly diagnosed in boys, more recently we have seen growing numbers of girls and women seeking diagnoses. However, some international experts <a href="https://academic.oup.com/shm/article/30/4/767/2919401">contest</a> the expanded definition of ADHD, driven by clinical practice in the United States. They argue the challenges of unwanted behaviours and educational outcomes for young people with the condition are uniquely shaped by each country’s cultural, political and local factors. Regardless of the name change to reflect what we know about the condition, ADHD continues to impact educational, social and life situations of many children, adolescents and adults.<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/225162/count.gif?distributor=republish-lightbox-basic" alt="The Conversation" width="1" height="1" /> <a href="https://theconversation.com/profiles/kathy-gibbs-1392051">Kathy Gibbs</a>, Program Director for the Bachelor of Education, <a href="https://theconversation.com/institutions/griffith-university-828">Griffith University</a> Image credits: Getty Images This article is republished from <a href="https://theconversation.com">The Conversation</a> under a Creative Commons license.

If you are looking instead for the truth – what the government is actually trying to achieve and what it is holding itself and its officials to, I would suggest something else, tucked away on about page <a href="https://cdn.theconversation.com/static_files/files/3225/8787.pdf">87</a> of the main budget document. It is required by the <a href="https://www.legislation.gov.au/C2004A05333/latest/text">Charter of Budget Honesty Act</a> introduced in 1998 by Peter Costello, the treasurer under Prime Minister John Howard. On taking office in 1996, Costello set up a <a href="https://webarchive.nla.gov.au/awa/20101119021633/http://www.finance.gov.au/archive/archive-of-publications/ncoa/execsum.htm">National Commission of Audit</a> to examine the finances he had inherited from the Hawke and Keating governments, presumably with an eye to discovering they had been mismanaged. But the members of the commission weren’t much interested in that. Instead, they decided to deal with something more fundamental. <h2>Budget as you wish, but explain your strategy</h2> Governments were perfectly entitled to manage money in whatever way they wanted, and they were perfectly entitled to spend more money than they raised (which they usually do, it’s called a <a href="https://www.investopedia.com/terms/d/deficit.asp">budget deficit</a>). What the commission wanted was for governments to make clear what they were doing, and to spell out the strategy behind it. Only part of it was about being upfront with the public. The commission also wanted governments to be upfront with themselves – to actually develop frameworks for what they were doing, rather than doing whatever they felt like. The commission recommended a <a href="https://webarchive.nla.gov.au/awa/20101119021633/http://www.finance.gov.au/archive/archive-of-publications/ncoa/execsum.htm">Charter of Budget Honesty</a>, which among other things requires officials to prepare independent assessments of the finances before each election, requires budget updates six months after each budget, and requires <a href="https://www.aph.gov.au/About_Parliament/Parliamentary_Departments/Parliamentary_Library/pubs/BriefingBook45p/TaxExpenditures">tax expenditures</a> (tax breaks) to be accounted for like other expenditures. And it requires the publication and regular updating of a <a href="https://cdn.theconversation.com/static_files/files/3227/CBH_Fiscal_strategy.pdf">fiscal strategy statement</a>. <h2>Where treasurers hold themselves accountable</h2> The <a href="https://cdn.theconversation.com/static_files/files/3225/8787.pdf">fiscal strategy</a> can be thought of as an exam question set by the student who is being examined – something along the lines of “this is what you say you want your budget to achieve, please set out the means by which you plan to achieve it”. It turns out to have been exceptionally effective in getting governments to organise their thoughts, make budgets at least try to achieve something, and let the rest of us know what they are trying to achieve. Every few years, treasurers change the strategy, as is their right. Treasurer Jim Chalmers says he’ll change it again this budget, to de-emphasise the fight against inflation and to more greatly emphasise the need to <a href="https://ministers.treasury.gov.au/ministers/jim-chalmers-2022/transcripts/press-conference-washington-dc-0">support economic growth</a>. His statement will tell us what’s behind his actions in a way the glossy words in his brochure and speech might not. <h2>The strategy that has signposted 26 years</h2> Previous statements have signposted all the important turns in what the budget is trying to do. The first, in <a href="https://images.theconversation.com/files/589686/original/file-20240423-16-rncqg3.PNG">1998</a>, committed Costello and Howard to achieving a budget surplus on average over the economic cycle and whenever “growth prospects remain sound”. Making that commitment more difficult was another “not to introduce new taxes or raise existing taxes over the term of this parliament”. Two years later, after the government had won an election promising a new goods and services tax, that commitment was <a href="https://images.theconversation.com/files/589692/original/file-20240423-18-q843xn.PNG">changed</a> to “no increase in the overall tax burden from its 1996-97 level”, a condition met by calling the GST a state tax. <h2>Hockey and Morrison wound back spending</h2> The Labor budgets from 2008 <a href="https://images.theconversation.com/files/589702/original/file-20240423-18-mikx6f.PNG">loosened</a> the tax target to the average share of GDP below the reference year, which they changed to the higher-tax year of 2007-08. The first Coalition budget under Treasurer Joe Hockey in 2014 changed the target from tax to spending, pledging to bring down the ratio of <a href="https://images.theconversation.com/files/589705/original/file-20240423-16-9spkdy.PNG">payments to GDP</a>, and pledging a surplus of 1% of GDP by 2023-24. Any new spending would be more than offset by cuts elsewhere, and if the budget did receive a burst of unexpected revenue it would be “banked” rather than spent. In 2018 Treasurer Scott Morrison reintroduced tax as a target, that he spelled out precisely. Tax was not to increase beyond <a href="https://images.theconversation.com/files/589706/original/file-20240423-16-b7gj5d.PNG">23.9%</a> of GDP. <h2>During COVID, Frydenberg spent big</h2> In 2020, in the face of a COVID-induced recession and soaring unemployment, Finance Minister Mathias Cormann and Treasurer Josh Frydenberg pushed the old strategy to one side. They would spend big now to keep the economy afloat so they wouldn’t have to spend more bailing it out later, and they wouldn’t return to their old concern about the deficit until the unemployment rate was “<a href="https://cdn.theconversation.com/static_files/files/3228/fs2020.pdf">comfortably below 6%</a>”. So well did they succeed that in 2021 Frydenberg made the momentous decision to keep going, abandoning the promise to return to worrying about the deficit when unemployment fell below 6%. Instead he promised to keep spending big until unemployment was “<a href="https://images.theconversation.com/files/589709/original/file-20240423-16-9pmpaf.PNG">back to pre-crisis levels or lower</a>”. The decision propelled unemployment down to a 50-year low of <a href="https://www.datawrapper.de/_/wPfXO/">3.5%</a>. Along with high iron ore prices, that one change of strategy has probably helped deliver Chalmers two consecutive budget surpluses – the one he announced last year for 2022-23, and the one he is set to announce this year for 2023-24. More of us have been in jobs <a href="https://www.finance.gov.au/publications/commonwealth-monthly-financial-statements/2024/mfs-january">paying tax</a>, and fewer have been out of jobs <a href="https://theconversation.com/half-a-million-more-australians-on-welfare-not-unless-you-double-count-227342">on benefits</a>. It’s a powerful demonstration of the real-world difference budget decisions can make, and the way in which the <a href="https://cdn.theconversation.com/static_files/files/3225/8787.pdf">fiscal strategy</a> tells the story.<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/228387/count.gif?distributor=republish-lightbox-basic" alt="The Conversation" width="1" height="1" /> <a href="https://theconversation.com/profiles/peter-martin-682709">Peter Martin</a>, Visiting Fellow, <a href="https://theconversation.com/institutions/crawford-school-of-public-policy-australian-national-university-3292">Crawford School of Public Policy, Australian National University</a> Image credits: Getty Images This article is republished from <a href="https://theconversation.com">The Conversation</a> under a Creative Commons license.

What to expect from the federal budget

There's just three weeks left until Treasurer Jim Chalmers unveils the federal budget. With the cost of living crisis still a major issue across the country, we can expect to see some policies aimed at alleviating the pressure. Some policies, have already been announced and here are a few others that we can expect to hear from Chalmers on May 14. Stage 3 cuts announced in January, will form a key part of this year's budget, which will direct more benefit towards low- and middle-income earners – although Australians on high salaries will still receive a tax cut. The decision was made to alleviate the cost-of-living pressures and partly address the bracket creep. The cuts lower the threshold for the lowest two brackets (so they pay less tax on that income), and raise the threshold for the highest two brackets (so they need to earn more to be taxed at a higher rate). This means that someone with average income of around $73,000 will get $1504, but how much you actually receive will depend on your income. The new version of the stage 3 cuts will come into effect on July 1. Superannuation will be paid on government-funded parental leave, with the change due to kick in for parents with babies born after July 1, 2025. They will receive a 12 per cent superannuation on top of their government-funded parental leave, with around 180,000 families expected to benefit from it. The figures will be included in the May 14 budget. Although nothing has been officially announced, there will likely be HECS-HELP debt relief for current and former students. "I think there's a range of areas where we need to do much better with the younger generation, and HECS is one of them," Prime Minister Anthony Albanese said on radio on April 18. "We've received a review of that... and what that has said is that the system can be made simpler and be made fairer. "We're examining the recommendations and we'll be making announcements pretty soon on that. We, of course, have a budget coming up." There have also been some hints from the government that energy bill relief will continue in this year's budget. "Our government understands that for small business – as for Australian families – energy bills remain a source of financial pressure," Albanese said, citing the existing policy that gives eligible families up to $500 off their power bills and eligible small businesses up to $650. "Our government understands that for small business – as for Australian families – energy bills remain a source of financial pressure," he said. "That's why the energy bill relief package I negotiated with the states and territories delivered up to $650 in savings for around 1 million small businesses, along with 5 million families. "And as we put together next month's budget, small businesses and families will again be front and centre in our thinking." Energy bills are also set to go down, or remain stable for the most part from July 1. Image: Getty

What happens when I stop taking a drug like Ozempic or Mounjaro?

<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> Drugs like Ozempic are very <a href="https://dom-pubs.pericles-prod.literatumonline.com/doi/10.1111/dom.12932">effective</a> at helping most people who take them lose weight. Semaglutide (sold as Wegovy and Ozempic) and tirzepatide (sold as Zepbound and Mounjaro) are the most well known in the class of drugs that mimic hormones to reduce feelings of hunger. But does weight come back when you stop using it? The short answer is yes. Stopping <a href="https://jamanetwork.com/journals/jama/fullarticle/2812936">tirzepatide</a> and <a href="https://doi.org/10.1111/dom.14725">semaglutide</a> will result in weight regain in most people. So are these medications simply another (expensive) form of yo-yo dieting? Let’s look at what the evidence shows so far. <h2>It’s a long-term treatment, not a short course</h2> If you have a bacterial infection, antibiotics will help your body fight off the germs causing your illness. You take the full course of medication, and the infection is gone. For obesity, taking tirzepatide or semaglutide can help your body get rid of fat. However it doesn’t fix the reasons you gained weight in the first place because obesity is a chronic, complex condition. When you stop the medications, the weight returns. Perhaps a more useful comparison is with high blood pressure, also known as hypertension. Treatment for hypertension is lifelong. It’s the same with obesity. Medications work, but only while you are taking them. (Though obesity is more complicated than hypertension, as many different factors both cause and perpetuate it.) Therefore, several concurrent approaches are needed; taking medication can be an important part of effective management but on its own, it’s often insufficient. And in an unwanted knock-on effect, stopping medication can undermine other strategies to lose weight, like eating less. <h2>Why do people stop?</h2> Research trials show anywhere from <a href="https://asean-endocrinejournal.org/index.php/JAFES/article/view/1771">6%</a> to <a href="https://pubmed.ncbi.nlm.nih.gov/35015037/">13.5%</a> of participants stop taking these drugs, primarily because of <a href="https://www.health.harvard.edu/staying-healthy/glp-1-diabetes-and-weight-loss-drug-side-effects-ozempic-face-and-more">side effects</a>. But these studies don’t account for those forced to stop because of cost or <a href="https://www.tga.gov.au/safety/shortages/information-about-major-medicine-shortages/about-ozempic-semaglutide-shortage-2022-and-2023">widespread supply issues</a>. We don’t know how many people have needed to stop this medication over the past few years for these reasons. Understanding what stopping does to the body is therefore important. <h2>So what happens when you stop?</h2> When you stop using tirzepatide or semaglutide, it takes several days (or even a couple of weeks) to <a href="https://pubmed.ncbi.nlm.nih.gov/30565096/">move out of your system</a>. As it does, a number of things happen: <ul> <li>you start feeling hungry again, because both <a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC4119845/">your brain and your gut</a> no longer have the medication working to make you feel full</li> </ul> <ul> <li> blood sugars increase, because the medication is no longer acting on the pancreas to help control this. If you have diabetes as well as obesity you may need to take other medications to keep these in an acceptable range. Whether you have diabetes or not, you may need to eat foods with a <a href="https://www.betterhealth.vic.gov.au/health/healthyliving/carbohydrates-and-the-glycaemic-index">low glycemic index</a> to stabilise your blood sugars </li> <li> over the longer term, most people experience a return to their <a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC10092593/">previous blood pressure and cholesterol levels</a>, as the weight comes back </li> <li> weight regain will mostly be in the form of fat, because it will be gained faster than skeletal muscle. </li> </ul> While you were on the medication, you will have lost <a href="https://academic.oup.com/jes/article/5/Supplement_1/A16/6240360">proportionally less skeletal muscle than fat</a>, muscle loss is inevitable when you lose weight, no matter whether you use medications or not. The problem is, when you stop the medication, your body preferentially puts on fat. <h2>Is stopping and starting the medications a problem?</h2> People whose weight fluctuates with tirzepatide or semaglutide may experience some of the downsides of <a href="https://pubmed.ncbi.nlm.nih.gov/21829159/">yo-yo dieting</a>. When you keep going on and off diets, it’s like a rollercoaster ride for your body. Each time you regain weight, your body has to <a href="https://www.jomes.org/journal/view.html?doi=10.7570/jomes.2017.26.4.237">deal with</a> spikes in blood pressure, heart rate, and how your body handles sugars and fats. This can <a href="https://cardiab.biomedcentral.com/articles/10.1186/s12933-022-01735-x">stress</a> your heart and overall cardiovascular system, as it has to respond to greater fluctuations than usual. Interestingly, the risk to the body from weight fluctuations is greater for people who are <a href="https://jech.bmj.com/content/74/8/662">not obese</a>. This should be a caution to those who are not obese but still using tirzepatide or semaglutide to try to lose unwanted weight. <h2>How can you avoid gaining weight when you stop?</h2> Fear of regaining weight when stopping these medications is valid, and needs to be addressed directly. As obesity has many causes and perpetuating factors, many evidence-based approaches are needed to reduce weight regain. This might include: <ul> <li> getting quality <a href="https://www.hindawi.com/journals/ije/2010/270832/">sleep</a> </li> <li> exercising in a way that builds and maintains muscle. While on the medication, you will <a href="https://pubmed.ncbi.nlm.nih.gov/32628589/">likely have lost muscle</a> as well as fat, although this is not inevitable, especially if you <a href="https://www.europeanreview.org/article/34169">exercise regularly</a> while taking it </li> </ul> <ul> <li> addressing emotional and cultural aspects of life that contribute to over-eating and/or eating unhealthy foods, and how you view your body. Stigma and shame around body shape and size is not cured by taking this medication. Even if you have a healthy relationship with food, we live in a culture that is <a href="https://ajph.aphapublications.org/doi/full/10.2105/AJPH.2009.159491">fat-phobic and discriminates</a> against people in larger bodies </li> <li> eating in a healthy way, hopefully continuing with habits that were formed while on the medication. Eating meals that have high nutrition and fibre, for example, and lower overall portion sizes. </li> </ul> Many people will stop taking tirzepatide or semaglutide at some point, given it is expensive and in short supply. When you do, it is important to understand what will happen and what you can do to help avoid the consequences. Regular reviews with your GP are also important. <hr /> Read the other articles in The Conversation’s <a href="https://theconversation.com/au/topics/ozempic-series-154673">Ozempic series</a> here.<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/224972/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: Getty Images This article is republished from <a href="https://theconversation.com">The Conversation</a> under a Creative Commons license.

"What has to happen?" Kyle Sandilands' controversial take after knife attacks

Kyle Sandilands has shared his controversial opinion on arming security guards in the wake of two violent stabbing attacks in Sydney. On Saturday, six people were killed at the hands of Joel Cauchi who went on a stabbing rampage through Bondi Junction Westfield, while on Monday night, a teenage boy stabbed a bishop and a priest during a church service in western Sydney. One of Joel Cauchi's victims was Faraz Tahir, a security guard at the shopping centre, while another guard was injured during the rampage. In the days after the eastern suburbs tragedy, Kyle, who has a <a href="https://oversixty.com.au/health/caring/kyle-sandilands-family-member-among-first-victims-stabbed-in-bondi" target="_blank" rel="noopener">connection</a> to one of the people injured during Cauchi's attack, launched into a tirade live on-air, calling for security guards to be given firearms. "I saw the [NSW] premier [Chris Minns] last night on TV saying firearms for security guards are not on the agenda. And I was like, 'Well, what has to happen before a security guard can actually secure the place for us?'" Sandilands raged. "Every shopping centre and every school should have armed security guards, trained specialists, not just some guy getting a little firearms licence. I mean, proper trained." Most retail security staff in NSW are unarmed, with batons classified as prohibited weapons that require special licensing and training. "There's people that work at Westfield, for example, women that work in shops that have told their husbands, 'I ain't never going back to Westfield. I'm never going back to work again'," Sandilands continued, adding that those retail workers are "traumatised forever" following Saturday's stabbings. Sandilands' opinions have been echoed by fellow controversial broadcaster Ray Hadley, who on Monday demanded on his 2GB Sydney radio show that security guards be armed across the state. "For years I've been arguing that all security guards in the state in hospitals and shopping centres should be better equipped," he said. "And these poor security guards, unarmed, unable to do what they should do - protecting the people that they are there to protect." Image credits: KIISFM

Surgery won’t fix my chronic back pain, so what will?

Patients are receiving costly, ineffective and risky care instead of effective, low-risk treatments for chronic pain. The challenge is considering how we might reimagine health-care delivery so the effective and safe treatments for chronic pain are available to millions of Australians who suffer from chronic pain. <a href="https://www.aihw.gov.au/getmedia/10434b6f-2147-46ab-b654-a90f05592d35/aihw-phe-267.pdf.aspx">One in five</a> Australians aged 45 and over have chronic pain (pain lasting three or more months). This costs an estimated <a href="https://www.aihw.gov.au/getmedia/10434b6f-2147-46ab-b654-a90f05592d35/aihw-phe-267.pdf.aspx">A$139 billion a year</a>, including $12 billion in direct health-care costs. The most common complaint among people with chronic pain is low back pain. So what treatments do – and don’t – work? <h2>Opioids and invasive procedures</h2> Treatments offered to people with chronic pain include strong pain medicines such as <a href="https://pubmed.ncbi.nlm.nih.gov/30561481/">opioids</a> and invasive procedures such as <a href="https://pubmed.ncbi.nlm.nih.gov/36878313/">spinal cord stimulators</a> or <a href="https://onlinelibrary.wiley.com/doi/full/10.1111/imj.14120">spinal fusion surgery</a>. Unfortunately, these treatments have little if any benefit and are associated with a risk of significant harm. <a href="https://bmchealthservres.biomedcentral.com/articles/10.1186/s12913-021-06900-8">Spinal fusion surgery</a> and <a href="https://privatehealthcareaustralia.org.au/consumers-urged-to-be-cautious-about-spinal-cord-stimulators-for-pain/#:%7E:text=Australian%20health%20insurance%20data%20shows,of%20the%20procedure%20is%20%2458%2C377.">spinal cord stimulators</a> are also extremely costly procedures, costing tens of thousands of dollars each to the health system as well as incurring costs to the individual. <h2>Addressing the contributors to pain</h2> Recommendations from the latest <a href="https://www.safetyandquality.gov.au/standards/clinical-care-standards/low-back-pain-clinical-care-standard">Australian</a> and <a href="https://www.who.int/publications/i/item/9789240081789">World Health Organization</a> clinical guidelines for low back pain focus on alternatives to drug and surgical treatments such as: <ul> <li>education</li> <li>advice</li> <li>structured exercise programs</li> <li>physical, psychological or multidisciplinary interventions that address the physical or psychological contributors to ongoing pain.</li> </ul> Two recent Australian trials support these recommendations and have found that interventions that address each person’s physical and psychological contributors to pain produce large and sustained improvements in pain and function in people with chronic low back pain. The interventions have minimal side effects and are cost-effective. In the <a href="https://jamanetwork.com/journals/jama/fullarticle/2794765">RESOLVE</a> trial, the intervention consists of pain education and graded sensory and movement “retraining” aimed to help people understand that it’s safe to move. In the <a href="https://pubmed.ncbi.nlm.nih.gov/37146623/">RESTORE</a> trial, the intervention (cognitive functional therapy) involves assisting the person to understand the range of physical and psychological contributing factors related to their condition. It guides patients to relearn how to move and to build confidence in their back, without over-protecting it. <h2>Why isn’t everyone with chronic pain getting this care?</h2> While these trials provide new hope for people with chronic low back pain, and effective alternatives to spinal surgery and opioids, a barrier for implementation is the out-of-pocket costs. The interventions take up to 12 sessions, lasting up to 26 weeks. One physiotherapy session <a href="https://www.sira.nsw.gov.au/__data/assets/pdf_file/0005/1122674/Physiotherapy-chiropractic-and-osteopathy-fees-practice-requirements-effective-1-February-2023.pdf">can cost</a> $90–$150. In contrast, <a href="https://www.servicesaustralia.gov.au/chronic-disease-individual-allied-health-services-medicare-items">Medicare</a> provides rebates for just five allied health visits (such as physiotherapists or exercise physiologists) for eligible patients per year, to be used for all chronic conditions. Private health insurers also limit access to reimbursement for these services by typically only covering a proportion of the cost and providing a cap on annual benefits. So even those with private health insurance would usually have substantial out-of-pocket costs. Access to trained clinicians is another barrier. This problem is particularly evident in <a href="https://www.ruralhealth.org.au/15nrhc/sites/default/files/B2-1_Bennett.pdf">regional and rural Australia</a>, where access to allied health services, pain specialists and multidisciplinary pain clinics is limited. Higher costs and lack of access are associated with the increased use of available and subsidised treatments, such as pain medicines, even if they are ineffective and harmful. The <a href="https://www.safetyandquality.gov.au/publications-and-resources/resource-library/data-file-57-opioid-medicines-dispensing-2016-17-third-atlas-healthcare-variation-2018">rate of opioid use</a>, for example, is higher in regional Australia and in areas of socioeconomic disadvantage than metropolitan centres and affluent areas. <h2>So what can we do about it?</h2> We need to reform Australia’s health system, private and <a href="https://www.health.gov.au/sites/default/files/documents/2020/12/taskforce-final-report-pain-management-mbs-items-final-report-on-the-review-of-pain-management-mbs-items.docx">public</a>, to improve access to effective treatments for chronic pain, while removing access to ineffective, costly and high-risk treatments. Better training of the clinical workforce, and using technology such as telehealth and artificial intelligence to train clinicians or deliver treatment may also improve access to effective treatments. A recent Australian <a href="https://pubmed.ncbi.nlm.nih.gov/38461844/">trial</a>, for example, found telehealth delivered via video conferencing was as effective as in-person physiotherapy consultations for improving pain and function in people with chronic knee pain.

Do optimists really live longer? Here’s what the research says

<a href="https://theconversation.com/profiles/fuschia-sirois-331254">Fuschia Sirois</a>, <a href="https://theconversation.com/institutions/durham-university-867">Durham University</a> Do you tend to see the glass as half full, rather than half empty? Are you always looking on the bright side of life? If so, you may be surprised to learn that this tendency could actually be good for your health. A <a href="https://content.apa.org/record/2020-71981-001">number of studies</a> have shown that optimists enjoy higher levels of wellbeing, better sleep, lower stress and even better cardiovascular health and immune function. And now, <a href="https://pubmed.ncbi.nlm.nih.gov/35674052/">a recent study</a> has shown that being an optimist is linked to longer life. To conduct their study, researchers tracked the lifespan of nearly 160,000 women aged between 50 to 79 for a period of 26 years. At the beginning of the study, the women completed a <a href="https://local.psy.miami.edu/people/faculty/ccarver/availbale-self-report-instruments/lot-r/">self-report measure of optimism</a>. Women with the highest scores on the measure were categorised as optimists. Those with the lowest scores were considered pessimists. Then, in 2019, the researchers followed up with the participants who were still living. They also looked at the lifespan of participants who had died. What they found was that those who had the highest levels of optimism were more likely to live longer. More importantly, the optimists were also more likely than those who were pessimists to live into their nineties. Researchers refer to this as “exceptional longevity”, considering the average lifespan for women is about 83 years in developed countries. What makes these findings especially impressive is that the results remained even after accounting for other factors known to predict a long life – including education level and economic status, ethnicity, and whether a person suffered from depression or other chronic health conditions. But given this study only looked at women, it’s uncertain whether the same would be true for men. However, <a href="https://www.pnas.org/doi/abs/10.1073/pnas.1900712116">another study</a> which looked at both men and women also found that people with the highest levels of optimism enjoyed a lifespan that was between 11% and 15% longer than those who were the least optimistic. <h2>The fountain of youth?</h2> So why is it that optimists live longer? At first glance it would seem that it may have to do with their healthier lifestyle. For example, <a href="https://www.ahajournals.org/doi/10.1161/CIRCRESAHA.117.310828">research from several studies</a> has found that optimism is linked to eating a healthy diet, staying physically active, and being less likely to smoke cigarettes. These healthy behaviours are well known to improve heart health and <a href="https://www.who.int/news-room/fact-sheets/detail/noncommunicable-diseases">reduce the risk</a> for cardiovascular disease, which is a <a href="https://www.who.int/news-room/fact-sheets/detail/cardiovascular-diseases-(cvds)">leading cause of death</a> globally. Adopting a healthy lifestyle is also <a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC3857242/">important for reducing the risk</a> of other potentially deadly diseases, such as diabetes and cancer. But having a healthy lifestyle may only be part of the reason optimists live a longer than average life. This latest study found that lifestyle only accounted for 24% of the link between optimism and longevity. This suggests a number of other factors affect longevity for optimists. Another possible reason could be due to the way optimists manage stress. When faced with a stressful situation, optimists tend to deal with it head-on. They <a href="https://pubmed.ncbi.nlm.nih.gov/16859439/">use adaptive coping strategies</a> that help them resolve the source of the stress, or view the situation in a less stressful way. For example, optimists will problem-solve and plan ways to deal with the stressor, call on others for support, or try to find a “silver lining” in the stressful situation. All of these approaches are well-known to reduce feelings of stress, as well as the biological reactions that occur when we feel stressed. It’s these <a href="https://www.apa.org/topics/stress/body">biological reactions to stress</a> –- such as elevated cortisol (sometimes called the “stress hormone”), increased heart rate and blood pressure, and impaired immune system functioning –- that can take a toll on health over time and increase the risk for developing <a href="https://www.sciencedirect.com/science/article/pii/S0889159115004316?via%3Dihub">life-threatening diseases</a>, such as cardiovascular disease. In short, the way optimists cope with stress may help protect them somewhat against its harmful effects. <h2>Looking on the bright side</h2> Optimism is typically viewed by researchers as a relatively stable personality trait that is determined by both <a href="https://www.cambridge.org/core/journals/twin-research-and-human-genetics/article/sex-differences-in-the-genetic-architecture-of-optimism-and-health-and-their-interrelation-a-study-of-australian-and-swedish-twins/58F21AA11943D44B4BA4C63A966E6AC7">genetic</a> and early childhood influences (such as having a <a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC6541423/">secure and warm relationship</a> with your parents or caregivers). But if you’re not naturally prone to seeing the glass as half full, there are some ways you can increase your <a href="https://www.tandfonline.com/doi/abs/10.1080/17439760.2016.1221122?journalCode=rpos20">capacity to be optimistic</a>. Research shows optimism can change over time, and can be cultivated by engaging in simple exercises. For example, visualising and then writing about your “<a href="https://www.psychologytoday.com/us/blog/what-matters-most/201303/what-is-your-best-possible-self">best possible self</a>” (a future version of yourself who has accomplished your goals) is a technique that studies have found can <a href="https://www.tandfonline.com/doi/full/10.1080/17439760.2016.1221122">significantly increase optimism</a>, at least temporarily. But for best results, the goals need to be both positive and reasonable, rather than just wishful thinking. Similarly, simply <a href="https://www.tandfonline.com/doi/abs/10.3200/SOCP.149.3.349-364">thinking about positive future events</a> can also be effective for boosting optimism. It’s also crucial to temper any expectations for success with an accurate view of what you can and can’t control. Optimism is reinforced when we experience the positive outcomes that we expect, and <a href="https://psycnet.apa.org/record/1970-20680-001">can decrease</a> when these outcomes aren’t as we want them to be. Although more research is needed, it’s possible that regularly envisioning yourself as having the best possible outcomes, and taking realistic steps towards achieving them, can help develop an optimistic mindset. Of course, this might be easier said than done for some. If you’re someone who isn’t naturally optimistic, the best chances to improve your longevity is by <a href="https://journals.plos.org/plosmedicine/article?id=10.1371/journal.pmed.1003332">living a healthy lifestyle</a> by staying physically active, eating a healthy diet, managing stress, and getting a good night’s sleep. Add to this cultivating a more optimistic mindset and you might further increase your chances for a long life.<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/184785/count.gif?distributor=republish-lightbox-basic" alt="The Conversation" width="1" height="1" /> <a href="https://theconversation.com/profiles/fuschia-sirois-331254">Fuschia Sirois</a>, Professor in Social & Health Psychology, <a href="https://theconversation.com/institutions/durham-university-867">Durham University</a> Image credits: Shutterstock This article is republished from <a href="https://theconversation.com">The Conversation</a> under a Creative Commons license.

Caring

Flash droughts are becoming more common in Australia. What’s causing them?

<a href="https://theconversation.com/profiles/milton-speer-703091">Milton Speer</a>, <a href="https://theconversation.com/institutions/university-of-technology-sydney-936">University of Technology Sydney</a> and <a href="https://theconversation.com/profiles/lance-m-leslie-437774">Lance M Leslie</a>, <a href="https://theconversation.com/institutions/university-of-technology-sydney-936">University of Technology Sydney</a> <a href="https://www.drought.gov/what-is-drought/flash-drought">Flash droughts</a> strike suddenly and intensify rapidly. Often the affected areas are in drought after just weeks or a couple of months of well-below-average rainfall. They happen worldwide and are <a href="https://www.researchgate.net/publication/377274397_Flash_drought_A_state_of_the_science_review?_tp=eyJjb250ZXh0Ijp7ImZpcnN0UGFnZSI6InB1YmxpY2F0aW9uRG93bmxvYWQiLCJwYWdlIjoicHVibGljYXRpb24iLCJwcmV2aW91c1BhZ2UiOiJwdWJsaWNhdGlvbiJ9fQ#read">becoming more common</a>, including in Australia, due to global warming. Flash droughts can occur anywhere and at any time of the year. Last year, a flash drought <a href="https://www.abc.net.au/news/2023-10-20/dams-dry-up-as-drought-takes-hold-in-hunter-valley/102996364">hit the Upper Hunter</a> region of New South Wales, roughly 300 kilometres north-west of Sydney. These sudden droughts can have devastating economic, social and environmental impacts. The damage is particularly severe for agricultural regions heavily dependent on reliable rain in river catchments. One such region is the Upper Hunter Valley, the subject of our <a href="https://www.mdpi.com/2225-1154/12/4/49">new research</a>. We identified two climate drivers – the <a href="http://www.bom.gov.au/climate/about/?bookmark=enso">El Niño Southern Oscillation</a> and <a href="http://www.bom.gov.au/climate/about/?bookmark=iod">Indian Ocean Dipole</a>) – that became influential during this drought. In addition, the waning influence of a third climate driver, the <a href="http://www.bom.gov.au/climate/about/?bookmark=sam">Southern Annular Mode</a>), would typically bring rain to the east coast. However, this rain did not reach the Upper Hunter. Flash droughts are set to get more common as the world heats up. This year, a flash drought developed over western and central Victoria over just two months. While heavy rain this month in Melbourne ended the drought there, it continues in the west. <h2>What makes a flash drought different?</h2> Flash droughts differ from more slowly developing droughts. The latter result from extended drops in rainfall, such as the <a href="http://www.bom.gov.au/climate/drought/">drought affecting</a> parts of southwest Western Australia due to the much shortened winter wet season last year. Flash droughts develop when sudden large drops in rainfall coincide with above-average temperatures. They mostly occur in summer and autumn, as was the case for Asia and Europe in 2022. That year saw flash droughts appear across the northern hemisphere, such as the megadrought affecting China’s <a href="https://iopscience.iop.org/article/10.1088/1748-9326/acfe21">Yangtze river basin</a> and <a href="https://www.sciencedirect.com/science/article/pii/S2352340923000264?via%3Dihub">Spain</a>. The flash drought devastating the Upper Hunter from May to October 2023 developed despite the region being drought-free just one month earlier. At that stage, almost nowhere in NSW showed any sign of an impending drought. <figure class="align-center "><img src="https://images.theconversation.com/files/586776/original/file-20240409-18-n82npo.jpg?ixlib=rb-1.1.0&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/586776/original/file-20240409-18-n82npo.jpg?ixlib=rb-1.1.0&q=45&auto=format&w=600&h=276&fit=crop&dpr=1 600w, https://images.theconversation.com/files/586776/original/file-20240409-18-n82npo.jpg?ixlib=rb-1.1.0&q=30&auto=format&w=600&h=276&fit=crop&dpr=2 1200w, https://images.theconversation.com/files/586776/original/file-20240409-18-n82npo.jpg?ixlib=rb-1.1.0&q=15&auto=format&w=600&h=276&fit=crop&dpr=3 1800w, https://images.theconversation.com/files/586776/original/file-20240409-18-n82npo.jpg?ixlib=rb-1.1.0&q=45&auto=format&w=754&h=347&fit=crop&dpr=1 754w, https://images.theconversation.com/files/586776/original/file-20240409-18-n82npo.jpg?ixlib=rb-1.1.0&q=30&auto=format&w=754&h=347&fit=crop&dpr=2 1508w, https://images.theconversation.com/files/586776/original/file-20240409-18-n82npo.jpg?ixlib=rb-1.1.0&q=15&auto=format&w=754&h=347&fit=crop&dpr=3 2262w" alt="Maps of drought conditions in NSW in April 2023 compared to the next six months" /><figcaption>NSW Department of Primary Industries’ combined drought indicator in April 2023 (a) and combined drought indicator for May–October 2023 (b) show how rapidly a flash drought developed in the Upper Hunter region. Milton Speer et al 2024, using NSW Department of Primary Industries' data</figcaption></figure> The flash drought greatly affected agricultural production in the Upper Hunter region, due to the region’s reliance on water from rivers. Low rainfall in river catchments means less water for crops and pasture. It also dries up drinking water supplies. Flash droughts are characterised by abrupt periods of low rainfall leading to rapid drought onset, particularly when accompanied by above-average temperatures. Higher temperatures increase both the evaporation of water from the soil and transpiration from plants (evapotranspiration). This causes soil moisture to drop rapidly. <h2>The Upper Hunter drought is part of a trend</h2> Flash droughts will be more common in the future. That’s because higher temperatures will more often coincide with dry conditions, as relative humidity falls <a href="https://www.researchgate.net/publication/377274397_Flash_drought_A_state_of_the_science_review_tp=eyJjb250ZXh0Ijp7ImZpcnN0UGFnZSI6InB1YmxpY2F0aW9uRG93bmxvYWQiLCJwYWdlIjoicHVibGljYXRpb24iLCJwcmV2aW91c1BhZ2UiOiJwdWJsaWNhdGlvbiJ9fQ#read">across many parts</a> of Australia and globally.

Milton Speer et al 2024</figcaption></figure> In south-east and south-west Australia, flash droughts can also occur in winter. In May 2023 rainfall over south-east Australia dropped abruptly. The much lower rainfall continued until November in the Upper Hunter. Over this same period, mean maximum temperatures in the region were the highest on record, increasing the loss of moisture through evapotranspiration. The result was a flash drought. While flash droughts occurred in other parts of south-east Australia, we focused on the Upper Hunter as it remained in drought the longest. <h2>What were the climate drivers of this drought?</h2> We used machine-learning techniques to identify the key climate drivers of the drought. We found the dominant driver of the flash drought was global warming, modulated by the phases of the three major climate drivers in our region, the El Niño Southern Oscillation, Indian Ocean Dipole and the Southern Annular Mode. From 2020 to 2022, the first two drivers became favourable for rain in the Upper Hunter in late winter through spring, before changing phase to one supporting drought over south-east Australia. Meanwhile, the Southern Annular Mode remained mostly positive, meaning rain-bearing westerly winds and weather fronts had moved to middle and higher latitudes of the southern hemisphere, away from Australia’s south-east coast. Combined, the impact of global warming with the three climate drivers made rainfall much more variable. The net result was an atmospheric environment highly conducive to a flash drought appearing anywhere in south-east Australia. <figure class="align-right zoomable"><a href="https://images.theconversation.com/files/586248/original/file-20240405-16-ti5j3m.png?ixlib=rb-1.1.0&q=45&auto=format&w=1000&fit=clip"><img src="https://images.theconversation.com/files/586248/original/file-20240405-16-ti5j3m.png?ixlib=rb-1.1.0&q=45&auto=format&w=237&fit=clip" sizes="(min-width: 1466px) 754px, (max-width: 599px) 100vw, (min-width: 600px) 600px, 237px" srcset="https://images.theconversation.com/files/586248/original/file-20240405-16-ti5j3m.png?ixlib=rb-1.1.0&q=45&auto=format&w=600&h=464&fit=crop&dpr=1 600w, https://images.theconversation.com/files/586248/original/file-20240405-16-ti5j3m.png?ixlib=rb-1.1.0&q=30&auto=format&w=600&h=464&fit=crop&dpr=2 1200w, https://images.theconversation.com/files/586248/original/file-20240405-16-ti5j3m.png?ixlib=rb-1.1.0&q=15&auto=format&w=600&h=464&fit=crop&dpr=3 1800w, https://images.theconversation.com/files/586248/original/file-20240405-16-ti5j3m.png?ixlib=rb-1.1.0&q=45&auto=format&w=754&h=583&fit=crop&dpr=1 754w, https://images.theconversation.com/files/586248/original/file-20240405-16-ti5j3m.png?ixlib=rb-1.1.0&q=30&auto=format&w=754&h=583&fit=crop&dpr=2 1508w, https://images.theconversation.com/files/586248/original/file-20240405-16-ti5j3m.png?ixlib=rb-1.1.0&q=15&auto=format&w=754&h=583&fit=crop&dpr=3 2262w" alt="Map of Upper Hunter region showing drought indicators in December 2023" /></a><figcaption>Intense drought conditions continued in the Upper Hunter in December 2023.

The flash drought followed very high January rainfall (top 5% of records) dropping rapidly to very low rainfall (bottom 5%) in February and March. It was the <a href="http://www.bom.gov.au/climate/maps/rainfall/?variable=rainfall&map=decile&period=2month&region=vc&year=2024&month=03&day=31">driest February-March period</a> on record for Melbourne and south-west Victoria. At the beginning of April, a storm front <a href="https://www.9news.com.au/national/severe-weather-storm-warning-for-victoria-and-melbourne-easter-monday/41d5d383-b70d-4d36-a649-38632bc607de">brought heavy rainfall</a> over an 18-hour period to central Victoria, including Melbourne. The rains ended the flash drought in these areas, but it continues in parts of western Victoria, which missed out on the rain. The pattern of the 2024 flash drought in Victoria typifies the increasing trend under global warming of long dry periods, interspersed by short, heavy rainfall events. <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/227052/count.gif?distributor=republish-lightbox-basic" alt="The Conversation" width="1" height="1" /> <a href="https://theconversation.com/profiles/milton-speer-703091">Milton Speer</a>, Visiting Fellow, School of Mathematical and Physical Sciences, <a href="https://theconversation.com/institutions/university-of-technology-sydney-936">University of Technology Sydney</a> and <a href="https://theconversation.com/profiles/lance-m-leslie-437774">Lance M Leslie</a>, Professor, School of Mathematical And Physical Sciences, <a href="https://theconversation.com/institutions/university-of-technology-sydney-936">University of Technology Sydney</a> Image credits: Getty Images This article is republished from <a href="https://theconversation.com">The Conversation</a> under a Creative Commons license.

50 years on, Advance Australia Fair no longer reflects the values of many. What could replace it?

<a href="https://theconversation.com/profiles/wendy-hargreaves-1373285">Wendy Hargreaves</a>, <a href="https://theconversation.com/institutions/university-of-southern-queensland-1069">University of Southern Queensland</a> On April 8 1974, Prime Minister Gough Whitlam announced to parliament the nation’s new national anthem: <a href="https://www.pmc.gov.au/honours-and-symbols/australian-national-symbols/australian-national-anthem">Advance Australia Fair</a>. Australia was growing up. We could stop saving “<a href="https://en.wikipedia.org/wiki/God_Save_the_King">our gracious Queen</a>” and rejoice in being “young” and “girt”. Finding a new anthem hadn’t been easy. There were unsuccessful <a href="https://www.naa.gov.au/help-your-research/fact-sheets/australias-national-anthem">songwriting competitions</a> and an unconvincing opinion poll. Finally, we landed on rebooting an Australian favourite from 1878. After Whitlam’s announcement, Australians argued, state officials declined the change and the next government reinstated the British anthem in part. It took another ten years, another poll and an official proclamation in 1984 to adopt the new anthem uniformly and get on with looking grown-up. Advance Australia Fair was never the ideal answer to “what shall we sing?”. The original lyrics ignored First Nations people and overlooked women. Like a grunting teenager, it both answered the question and left a lot out. On its 50th anniversary, it’s time to consider whether we got it right. Advance Australia Fair may have helped Australia transition through the 1970s, but in 2024, has it outstayed its welcome? <h2>How do you pick a national anthem?</h2> A national anthem is a government-authorised song performed at official occasions and celebrations. It unifies people and reinforces national identity. Often, governments nominate a tune by searching through historical patriotic songs to find a <a href="https://dictionary.cambridge.org/dictionary/english/golden-oldie">golden oldie</a> with known public appeal. For example, the lyrics of the Japanese anthem <a href="https://en.wikipedia.org/wiki/Kimigayo">Kimigayo</a> came from pre-10th-century poetry. Germany’s anthem <a href="https://www.britannica.com/topic/Deutschlandlied">Deutschlandlied</a> adopted a 1797 melody from renowned composer <a href="https://www.britannica.com/biography/Joseph-Haydn">Joseph Haydn</a>. An enduring song or text offers star quality, proven popularity and the prestige of age. In the 1970s, Australia’s attempt at finding a golden oldie was flawed. In that era, many believed Australia’s birth occurred at the arrival of explorer <a href="https://www.britannica.com/biography/James-Cook">James Cook</a> in 1770. Hence, we narrowed our search to hymns, marches and fanfares from our colonial history for possible anthems. With 2020s hindsight (pun intended), <a href="https://theconversation.com/our-national-anthem-is-non-inclusive-indigenous-australians-shouldnt-have-to-sing-it-118177">expecting First Nations</a> people to sing Advance Australia Fair was hypocritical. We wanted to raise Australia’s visibility internationally, yet the custodians of the lands and waterways were unseen by our country’s eyes. We championed “history’s page” with a 19th-century song that participated in racial discrimination. <h2>Changing anthems</h2> With a half-century on the scoreboard, are we locked in to singing Advance Australia Fair forever? No. Anthems can change. Just ask <a href="https://en.wikipedia.org/wiki/James_Morrison_(jazz_musician)">James Morrison</a>. In 2003, the Australian trumpeter played the Spanish national anthem beautifully at the <a href="https://www.daviscup.com/en/home.aspx">Davis Cup</a> tennis final. Unfortunately, he <a href="https://www.abc.net.au/news/2003-11-28/spanish-angry-over-anthem-mix-up/1516684">played the old anthem</a> that heralded civil war. Morrison’s accidental performance incited a fist-shaking dignitary and an enraged Spanish team who temporarily refused to play. Morrison did, however, to his embarrassment, later receive some excited fan mail from Spanish revolutionists. If we want to change our anthem, where could we begin? We could start by revisiting the golden-oldie approach with a more inclusive ear. Perhaps there’s a song from contemporary First Nations musicians we could consider, or a song from their enduring oral tradition that they deem appropriate (and grant permission to use). If we have learnt anything from Australian history, it’s that we must include and ask – not exclude and take. We could also consider Bruce Woodley and Dobe Newton’s 1987 song <a href="https://www.nfsa.gov.au/collection/curated/asset/101146-i-am-australian-various">I Am Australian</a>, which reached golden-oldie status last year when the <a href="https://www.nfsa.gov.au/slip-slop-slap-i-am-australian-join-sounds-australia">National Film and Sound Archive</a> added it to their registry. The lyrics show the acknowledgement and respect of First Nations people that our current anthem lacks. The line “we are one, but we are many” captures the inclusivity with diversity we now value. <figure><iframe src="https://www.youtube.com/embed/KrLTe1_9zso?wmode=transparent&start=0" width="440" height="260" frameborder="0" allowfullscreen="allowfullscreen"></iframe></figure> I Am Australian wouldn’t be a problem-free choice. Musically, the style is a “light rock” song, not a grand “hymn”, which could be a plus or minus depending on your view. Lyrically, romanticising convicted killer <a href="https://adb.anu.edu.au/biography/kelly-edward-ned-3933">Ned Kelly</a> is controversial, and mispronouncing “Australians” could be considered inauthentic (fair dinkum Aussies say “Au-strail-yins”, not “Au-stray-lee-uhns”). That said, Australians are quite experienced at patching holes in our anthem. Advance Australia Fair required many adjustments. If the golden-oldie approach fails again, how about composing a new anthem? We could adopt <a href="https://nationalanthems.info/ke.htm">Kenya’s approach</a> of commissioning an anthem, or could revive the good ol’ songwriting competition. Our past competitions weren’t fruitful, but surely our many talented musicians and poets today can meet the challenge. <h2>It’s time to ask</h2> Fifty years on, we acknowledge Advance Australia Fair as the anthem that moved our nation forward. That was the first and hardest step. Today, if Australians choose, we can retire the song gracefully and try again with a clearer voice. Changing our anthem begins with asking whether the current song really declares who we are. Have our values, our perspectives and our identity changed in half a century? Australia, it’s your song. Are you happy to sing Advance Australia Fair for another 50 years? <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/226737/count.gif?distributor=republish-lightbox-basic" alt="The Conversation" width="1" height="1" /> <a href="https://theconversation.com/profiles/wendy-hargreaves-1373285">Wendy Hargreaves</a>, Senior Learning Advisor, <a href="https://theconversation.com/institutions/university-of-southern-queensland-1069">University of Southern Queensland</a> This article is republished from <a href="https://theconversation.com">The Conversation</a> under a Creative Commons license.

Silent cancers: here’s what you need to know when there are no obvious symptoms

<a href="https://theconversation.com/profiles/justin-stebbing-1405462">Justin Stebbing</a>, <a href="https://theconversation.com/institutions/anglia-ruskin-university-1887">Anglia Ruskin University</a> The recent revelations about the Princess of Wales’s <a href="https://www.bbc.com/news/uk-68640917">cancer diagnosis</a> highlight a crucial aspect of cancer detection – the disease’s sometimes silent nature. Silent cancers are those without noticeable symptoms. They pose a unique challenge in early detection and treatment. Contrary to common perception, cancer does not always announce its presence through overt symptoms or obvious signs. Many people receive a <a href="https://academic.oup.com/clinchem/article-abstract/70/1/179/7283928">cancer diagnosis incidentally</a>, when it’s found during routine medical examinations or investigations for unrelated health concerns – as seems to be the case for both <a href="https://www.wsj.com/health/kate-middleton-catherine-cancer-what-is-preventative-chemotherapy-9625370d">the princess</a> and <a href="https://www.bbc.co.uk/news/health-68171163">King Charles III</a>. While even silent cancers can sometimes be <a href="https://pubmed.ncbi.nlm.nih.gov/22584215/">aggressive and advance rapidly</a>, they can also remain <a href="https://pubmed.ncbi.nlm.nih.gov/20363069/">dormant</a> for years or <a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC8819710/">even decades</a>. Some <a href="https://ascopubs.org/doi/10.14694/EdBook_AM.2012.32.98">prostate</a>, <a href="https://ascopubs.org/doi/10.14694/EdBook_AM.2012.32.301">breast</a> and <a href="https://www.frontiersin.org/journals/endocrinology/articles/10.3389/fendo.2020.571421/full">thyroid</a> cancers, for example, <a href="https://www.tmlep.com/clinical-learning/2023-01-23-when-did-this-tumour-start-the-need-for-a-gompertzian-understanding-of-tumour-growth-kinetics">often evolve slowly</a> without obvious symptoms or spreading beyond the original area. Research suggests that some of these cancers are <a href="https://www.frontiersin.org/journals/endocrinology/articles/10.3389/fendo.2020.571421/full">overtreated</a>. Sometimes patients are best left alone or treated much more gently, perhaps even without medical intervention, using a <a href="https://www.nejm.org/doi/full/10.1056/nejmoa1311593">“watch and wait”</a> strategy. This approach may be taken with prostate cancer in the elderly, for example. <h2>The importance of early diagnosis</h2> Whatever the cancer, it’s always important to get an early diagnosis though – and for silent cancers, this is obviously a challenge. Some cancer symptoms <a href="https://pubmed.ncbi.nlm.nih.gov/36702593/">can be vague</a> and easily mistaken for benign ailments. Fatigue, unexplained weight loss and persistent pain are among the nonspecific symptoms that may signal an underlying malignancy. But such symptoms can be misinterpreted or easily dismissed, which contributes to delayed diagnosis and treatment. <figure><iframe src="https://www.youtube.com/embed/MGMy6BzBvp0?wmode=transparent&start=0" width="440" height="260" frameborder="0" allowfullscreen="allowfullscreen"></iframe></figure> Fortunately, in many countries including the UK, we have <a href="https://www.england.nhs.uk/cancer/early-diagnosis/screening-and-earlier-diagnosis/">screening</a> tests for diseases like breast or colon cancer, to increase early diagnoses. Early diagnosis is a <a href="https://acsjournals.onlinelibrary.wiley.com/doi/full/10.1002/cncr.32887">key factor</a> for successful cancer treatment. Detecting cancer in its silent phase offers a window of opportunity for early intervention and improved outcomes. The discovery of asymptomatic cancers through diagnostic imaging or screening tests underscores the importance of these proactive healthcare measures. Identifying cancer at an early stage means the disease is confined to its site of origin, smaller and potentially easier to cure. Diagnosing a smaller cancer often means that if an operation is needed, it may be a less invasive surgery. There may also be a <a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC6825992/">lower chance</a> of needing post-operative preventative chemotherapy, to mop up any residual cells. Colorectal cancer (CRC) is a good example to show the critical importance of screening. Studies show that patients who participate in CRC <a href="https://www.nice.org.uk/guidance/dg56/chapter/1-Recommendations">screening</a>, such as colonoscopies or tests that look for blood in the stool, are more likely to be diagnosed while asymptomatic and have more positive prognoses after treatment. Those diagnosed with CRC after showing symptoms, such as rectal bleeding or changes in bowel habits, tend to have more <a href="https://bmjopengastro.bmj.com/content/4/1/e000146%20">advanced tumors and poorer outcomes</a>. <figure><iframe src="https://www.youtube.com/embed/nA9_Io3LDpA?wmode=transparent&start=0" width="440" height="260" frameborder="0" allowfullscreen="allowfullscreen"></iframe></figure> Public health initiatives aimed at raising awareness about the importance of both cancer screening and symptom recognition play a pivotal role in reducing diagnostic delays. Empowering people to engage in <a href="https://healthcaredelivery.cancer.gov/prevention/#:%7E:text=Cancer%20can%20be%20prevented%20through,they%20are%20more%20easily%20treated.">preventive healthcare measures</a> such as HPV vaccinations and lifestyle changes that decrease risk can facilitate early detection and intervention, potentially altering the trajectory of the disease. <h2>Biomarker discovery</h2> The latest advances in diagnostic technologies, often known as <a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC8012218/#:%7E:text=During%20biomarker%20discovery%2C%20evaluation%20of,design%20of%20future%20validation%20studies.">“biomarker discovery”</a>, hold promise for improving early detection rates and refining treatment strategies for silent cancers. From <a href="https://www.cancer.gov/publications/dictionaries/cancer-terms/def/molecular-profiling">molecular profiling</a> to <a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC9922467/">liquid biopsy techniques</a> (blood tests to diagnose cancer), innovative approaches are reshaping the landscape of cancer diagnosis, offering new avenues for personalised and precision medicine. For example, I worked with a team using blood tests to identify cancers in more than <a href="https://www.nature.com/articles/s41388-023-02591-z">1,000 women recalled after screening for mammography</a>. We looked at the DNA that tumour cells release – so-called <a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC10496721/">cell-free DNA</a> – and also metabolomics (rare markers related to metabolism in the blood). From this information, we found healthy patients, benign disease, pre-cancer and breast cancer. Although there’s increasing awareness and use of this <a href="https://www.sciencedirect.com/science/article/abs/pii/S1769721218307110">approach in Europe</a>, it isn’t standard in the UK. Asymptomatic cancers represent a formidable challenge for patient care. But, by encouraging patients to adopt preventive lifestyles and engage with screenings and tests, asymptomatic cancers don’t have to be a hidden threat to health.<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/226536/count.gif?distributor=republish-lightbox-basic" alt="The Conversation" width="1" height="1" /> <a href="https://theconversation.com/profiles/justin-stebbing-1405462">Justin Stebbing</a>, Professor of Biomedical Sciences, <a href="https://theconversation.com/institutions/anglia-ruskin-university-1887">Anglia Ruskin University</a> Image credits: Getty Images This article is republished from <a href="https://theconversation.com">The Conversation</a> under a Creative Commons license.
