The internet is worse than it used to be. How did we get here, and can we go back?

<div class="theconversation-article-body"><em><a href="https://theconversation.com/profiles/marc-cheong-998488">Marc Cheong</a>, <a href="https://theconversation.com/institutions/the-university-of-melbourne-722">The University of Melbourne</a> and <a href="https://theconversation.com/profiles/wonsun-shin-1300054">Wonsun Shin</a>, <a href="https://theconversation.com/institutions/the-university-of-melbourne-722"><em>The University of Melbourne</em></a></em></p> <p>When it comes to our experience of the internet, “the times, <a href="https://en.wikipedia.org/wiki/The_Times_They_Are_a-Changin%27_(song)">they are a-changin’</a>”, as Bob Dylan would say. You can’t quite recall how, but the internet certainly feels different these days.</p> <p>To some, it is “<a href="https://www.npr.org/2024/01/16/1224878097/everyday-users-are-complaining-that-the-internet-is-more-chaotic-than-ever">less fun and less informative</a>” than it used to be. To others, online searches are made up of “<a href="https://www.theverge.com/c/23998379/google-search-seo-algorithm-webpage-optimization?src=longreads">cookie cutter</a>” pages that drown out useful information and are saturated with scams, spam and content generated by artificial intelligence (AI).</p> <p>Your social media feeds are full of eye-catching, provocative, hyper-targeted, or anger-inducing content, from <a href="https://theconversation.com/the-dead-internet-theory-makes-eerie-claims-about-an-ai-run-web-the-truth-is-more-sinister-229609">bizarre AI-generated imagery</a> to robot-like comments. You’re lucky if your video feeds are not solely made up of exhortations to “subscribe”.</p> <p>How did we get here? And can we claw our way back?</p> <h2>Commercial interests rule</h2> <p>One major factor contributing to the current state of the internet is its over-commercialisation: financial motives drive much of the content. This has arguably led to the prevalence of sensationalism, prioritising virality over information quality.</p> <p>Covert and deceptive advertising is widespread, blurring the line between commercial and non-commercial content to attract more attention and engagement.</p> <p>Another driving force is the dominance of tech giants like Google, Meta and Amazon. They reach billions worldwide and wield immense power over the content we consume.</p> <p>Their platforms use advanced tracking technologies and opaque algorithms to generate hyper-targeted media content, powered by extensive user data. This creates <a href="https://www.campaignasia.com/article/the-echo-chamber-effect-how-algorithms-shape-our-worldview/491762">filter bubbles</a>, where users are exposed to limited content that reinforces their existing beliefs and biases, and <a href="https://philarchive.org/archive/NGUECA">echo chambers</a> where other viewpoints are actively discredited.</p> <p>Bad actors like <a href="https://abcnews.go.com/Technology/ai-fuel-financial-scams-online-industry-experts/story?id=103732051">cyber criminals and scammers</a> have been an enduring problem online. However, evolving technology like generative AI has further empowered them, enabling them to create highly realistic fake images, deepfake videos and <a href="https://www.newyorker.com/science/annals-of-artificial-intelligence/the-terrifying-ai-scam-that-uses-your-loved-ones-voice">voice cloning</a>.</p> <p>AI’s ability to automate content creation has also flooded the internet with low-quality, misleading and harmful material at an unprecedented scale.</p> <p>In sum, the accelerated commercialisation of the internet, the dominance of media tech giants and the presence of bad actors have infiltrated content on the internet. The rise of AI further intensifies this, making the internet more chaotic than ever.</p> <h2>Some of the ‘good’ internet remains</h2> <p>So, what was the “good internet” some of us long for with nostalgia?</p> <p>At the outset, the internet was meant to be a free egalitarian space people were meant to “surf” and “browse”. Knowledge was meant to be shared: sites such as Wikipedia and The Internet Archive are continuing bastions of knowledge.</p> <p>Before the advent of filter bubbles, the internet was a creative playground where people explored different ideas, discussed varying perspectives, and collaborated with individuals from “outgroups” – those outside their social circles who may hold opposing views.</p> <p>Early social media platforms were built on the ethos of reconnecting with long-lost classmates and family members. Many of us have community groups, acquaintances and family we reach out to via the internet. The “connection” aspect of the internet remains as important as ever – as we all saw during the COVID pandemic.</p> <p>What else do we want to preserve? Privacy. A New Yorker cartoon joke in 1993 stated that “<a href="https://web.archive.org/web/20051029045942/http://www.unc.edu/depts/jomc/academics/dri/idog.html">on the internet, nobody knows you’re a dog</a>”. Now everyone – especially advertisers – wants to know who you are. To quote the <a href="https://www.oaic.gov.au/privacy/your-privacy-rights/your-personal-information/what-is-privacy">Office of the Australian Information Commissioner</a>, one of the tenets of privacy is “to be able to control who can see or use information about you”.</p> <p>At the very least, we want to control what big tech knows about us, especially if they could stand to profit from it.</p> <h2>Can we ever go back?</h2> <p>We can’t control “a changin’” times, but we can keep as much of the good parts as we can.</p> <p>For starters, we can vote with our feet. Users can enact change and bring awareness to problems on existing platforms. In recent times, we have seen this with the <a href="https://theconversation.com/thinking-of-breaking-up-with-twitter-heres-the-right-way-to-do-it-195002">exodus of users</a> from X (formerly Twitter) to other platforms, and the <a href="https://www.economist.com/the-economist-explains/2023/06/26/why-reddit-users-are-protesting-against-the-sites-leadership">platform-wide protest against Reddit</a> for changing its third-party data access policies.</p> <p>However, voting with our feet is only possible when there’s competition. In the case of X, various other platforms – from Mastodon to Threads to Bluesky – enable users to pick one that aligns with their preferences, values and social circles. Search engines have alternatives, too, such as DuckDuckGo or Ecosia.</p> <p>But competition can only be created by moving to decentralised systems and removing monopolies. This actually happened in the early days of the internet during the 1990s “<a href="https://thehistoryoftheweb.com/browser-wars/">browser wars</a>”, when Microsoft was eventually accused of illegally monopolising the web browser market in <a href="https://en.wikipedia.org/wiki/United_States_v._Microsoft_Corp.">a landmark court case</a>.</p> <p>As users of technology, all of us must remain vigilant about threats to our privacy and knowledge. With cheap and ubiquitous generative AI, misleading content and scams are more realistic as ever.</p> <p>We must exercise healthy scepticism and ensure those most at risk from online threats – such as children and older people – are educated about potential harms.</p> <p>Remember, the internet is not optimised for your best interests. It’s up to you to decide how much power you give to the tech giants who are fuelling theirs.<!-- Below is The Conversation's page counter tag.

Doting dad sells everything he owns to develop cure for son's "incurable" condition

<p>A dedicated father has drained his life savings to help find a cure for his son's "incurable" disorder. </p> <p>Terry Pirovolakis, a 44-year-old IT director, was hellbent on finding a cure for his six-year-old son Michael after he was diagnosed with Spastic paraplegia 50 (SPG50): a degenerative neurological condition that affects less than 100 people worldwide. </p> <p>SPG50 affects children's development, leading to cognitive impairment, muscle weakness, and paralysis over the course several years, often ending in death usually before a patient reaches the age of 30.</p> <p>"They said he'd never walk or talk, and would need support for the rest of his life," he recalled of the 2018 diagnosis. </p> <p>"They told us to just go home and love him - and said he would be paralysed from the waist down by age 10, and quadriplegic by age 20," he continued. </p> <p>Determined to save his son, Terry drained his life savings to start researching potential cures rooted in gene therapy, after reading countless journals on the subject and meeting with experts around the world. </p> <p>Terry said, "We then liquidated our life savings, refinanced our home and paid a team at the University of Texas Southwestern Medical Center to create a proof of concept to start Michael's gene therapy."</p> <p>The father soon signed a contract to start a gene therapy program, consisting of injecting cerebral spinal fluid into the patient's back, and after years of lab work, the treatment started to take, and on December 30th 2021, the government <a id="mol-70453400-6948-11ef-9b54-1d20db350cbd" href="https://www.dailymail.co.uk/news/canada/index.html" target="_self"></a>moved it forward.</p> <p>"On March 24, 2022, my son was the first person to ever get treated with gene therapy at SickKids in Toronto," Pirovolakis, a father of three, told <em>Fox News</em> in detailing his medical odyssey.</p> <p>Michael was the first to receive his father's one-time treatment, after Pirovolakis quit his job and started a nonprofit in California to devote himself to the cause.</p> <p>The company, named Elpida Therapeutics, after the Greek word for 'hope', now has five employees and 20 consultants, with Michael now on the mend.</p> <p>Since being treated, the youngster's condition seems to have stabilised, and he is now able to use a device to communicate with his family and caregivers.</p> <p>Another three children who were able to receive the remaining doses from Pirovolakis' first batch, as the drug still costs about $1million to make for each child, are also seeing positive results. </p> <p>"When I heard that no one was going to do anything about it, I had to - I couldn't let them die," Pirovolakis said. "We decided that we had to help other kids."</p> <p>Despite it being approved, big pharmaceutical companies have been slow to manufacture the drug, with several firms rejecting the prospect when proposed, Pirovolakis said</p> <p>"No investor is going to give you money to treat a disease that is not going to make money," he said. "That's the dilemma we're in."</p> <p>Pirovolakis said that when his son was diagnosed, he was told the boy would be paralysed from the waist down by the age of ten and quadriplegic by the age of 20, forcing the father to do everything he can.</p> <p>"We were told he would never speak or walk, and that he will have severe developmental delays. I just couldn't accept that fate for my child," he said.</p> <p>"The technology to cure our children is already here. I hope that someone with immense wealth - and more importantly, the vision and influence - will step in."</p> <p><em>Image credits: Facebook</em></p>

Does eating ham, bacon and beef really increase your risk of developing type 2 diabetes?

<div class="theconversation-article-body"><em><a href="https://theconversation.com/profiles/duane-mellor-136502">Duane Mellor</a>, <a href="https://theconversation.com/institutions/aston-university-1107">Aston University</a></em></p> <p>That lunchtime staple, the humble ham sandwich, has come in for a bashing in the press recently. According to <a href="https://www.theguardian.com/society/article/2024/aug/20/two-slices-of-ham-a-day-can-raise-type-2-diabetes-risk-by-15-research-suggests">many</a> <a href="https://www.dailymail.co.uk/health/article-13761253/Eating-ham-daily-linked-increase-risk-diabetes.html">reports</a>, eating two slices of ham a day can increase your risk of developing type 2 diabetes.</p> <p>But what’s the science behind these headlines?</p> <p>The research offers a more complex picture. <a href="https://www.thelancet.com/journals/landia/article/PIIS2213-8587(24)00179-7/fulltext">A new study</a> from the University of Cambridge highlighted an association between developing type 2 diabetes and eating processed meat like ham and bacon, and red meat such as beef and lamb.</p> <p>This led to headlines suggesting the risk was mainly linked to <a href="https://www.telegraph.co.uk/news/2024/08/21/ham-sandwich-processed-meat-fresh-risk-link-type-2-diabetes/">ham sandwiches</a>. This seems to have come from the <a href="https://www.cam.ac.uk/research/news/red-and-processed-meat-consumption-associated-with-higher-type-2-diabetes-risk">press release</a>, which used ham as the example to quantify the amount of processed meat associated with a 15% increased risk of developing type 2 diabetes over ten years.</p> <p>The research found that this risk was linked to eating an extra 50g of processed meat every day, which happens to equate to two slices of ham. A useful example thus appears to have been taken up by the media as the main cause, perhaps ignoring some of the key messages coming from the study.</p> <p>So, can processed and red meat really increase your risk of developing type 2 diabetes?</p> <p>The <a href="https://www.diabetes.org.uk/diabetes-the-basics/types-of-diabetes/type-2/diabetes-risk-factors">biggest risk factors</a> linked to developing type 2 diabetes are being over 40, having family members with type 2 diabetes, being of South Asian or African descent, or having a higher body weight – and especially a larger waist.</p> <figure><iframe src="https://www.youtube.com/embed/EsOBcx2bJqU?wmode=transparent&amp;start=0" width="440" height="260" frameborder="0" allowfullscreen="allowfullscreen"></iframe></figure> <p>The Cambridge study used data from nearly 2 million people from 31 studies. Participants were followed for an average of ten years. During this time, around one in 20 people developed type 2 diabetes.</p> <p>The research suggested that a 10% increase in the probability of developing type 2 diabetes was associated with every 100g of additional red meat eaten daily. Eating half as much extra processed meat every day was linked to an even greater increased risk of developing the disease.</p> <p>This is not the <a href="https://ajcn.nutrition.org/article/S0002-9165(23)66119-2/abstract">first time</a> that both processed and red meats have been linked with an increased risk of developing type 2 diabetes. However, the key strength of the Cambridge study was that it tried to control for many of the other factors linked to the disease, including smoking, having a higher body weight, dietary intake and exercise.</p> <p>However, the size of the increased risk is modest, considering few people included in the study ate 50g or more processed meat per day – meaning moderate ham consumption is likely to have <a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC9908545/">no meaningful effect</a> on your risk.</p> <h2>What’s the link?</h2> <p>Processed meat has been linked to increased risk of type 2 diabetes because of its nitrate and salt content – additives that are used to cure many processed meats.</p> <p>Nitrates and salt in processed meats have also <a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC6893523/">been linked to</a> an increased risk of developing colon cancer. In fact, the World Health Organization classifies the additives as <a href="https://www.who.int/news-room/questions-and-answers/item/cancer-carcinogenicity-of-the-consumption-of-red-meat-and-processed-meat">group 1 carcinogens</a>, which means they can cause a range of cancers.</p> <p>The mechanism linking processed meat to cancer seems to be similar to how it might be linked to type 2 diabetes. During digestion, processed meat produces <a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC6294997/">N-nitroso chemicals</a>, which can damage cells. This can lead to inflammation and affects how insulin, the hormone that controls blood glucose (sugar), works. This in turn can lead to <a href="https://www.niddk.nih.gov/health-information/diabetes/overview/what-is-diabetes/prediabetes-insulin-resistance">insulin resistance</a>, when cells in your muscles, fat and liver don’t respond well to insulin and can’t easily take up glucose from your blood.</p> <p>Red meat, meanwhile, is <a href="https://www.healthline.com/nutrition/healthy-iron-rich-foods">rich in iron</a>. Research suggests that people with <a href="https://www.diabetes.org.uk/diabetes-the-basics/related-conditions/haemochromatosis-diabetes#:%7E:text=So%20a%20rise%20of%20iron,GP%20as%20soon%20as%20possible.">high levels of iron</a> are more likely to develop type 2 diabetes. However, <a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC8744124/#:%7E:text=The%20WHO%20has%20recognised%20iron,being%20affected%20with%20this%20condition.">low levels of iron</a> are more of a health concern for the general population.</p> <p>Another potential link regarding red meat could be the way it is cooked.</p> <p><a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC5521980/">Previous studies</a> have suggested that charred meat, cooked over an open flame or at high temperature, is also linked to an increased risk of developing <a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC5911789/">type 2 diabetes</a>. Charring meat leads to formation of toxic chemicals such as <a href="https://www.sciencedirect.com/topics/pharmacology-toxicology-and-pharmaceutical-science/heterocyclic-amine#:%7E:text=Heterocyclic%20amines%20are%20aromatic%20compounds,of%20reactions%20called%20Maillard%20reactions.">heterocyclic aromatic amines</a> and harmful compounds like <a href="https://www.healthline.com/nutrition/advanced-glycation-end-products">advanced glycation end products</a>, both of which have been linked to <a href="https://pubmed.ncbi.nlm.nih.gov/21709297/">insulin resistance and type 2 diabetes</a>.</p> <h2>Bye-bye barbecues and bacon butties?</h2> <p>The key message is reduction, rather than avoidance. The UK government nutritional recommendations offer sound advice: limit your combined intake of red and processed meat to no more than <a href="https://www.nhs.uk/live-well/eat-well/food-types/meat-nutrition/#:%7E:text=Red%20meat%20and%20processed%20meat&amp;text=If%20you%20currently%20eat%20more,%2C%20veal%2C%20venison%20and%20goat.">an average of 70g per day</a>.</p> <p>But these guidelines also suggest that red meat can be a valuable source of iron. So, if you decide to stop eating red meat, you should eat alternative sources of iron such as beans, lentils, dark green vegetables and fortified cereals.</p> <p>This needs to be done as part of a carefully planned diet. Non-meat sources of iron are more difficult for our bodies to absorb so should be eaten with a source of vitamin C, found in green vegetables and citrus fruit.</p> <p>The best advice to reduce your risk of developing type 2 diabetes is to maintain a healthy weight – consider losing weight if you have a higher body weight – and be as physically active as possible.</p> <p>A healthy diet should be based on plenty of vegetables, fruit, beans, peas, lentils, nuts and seeds, along with some wholegrain foods, some dairy products, fish and white meat (or vegetarian alternatives) – plus moderate amounts of red meat and minimal processed meat. This will help reduce your risk of type 2 diabetes, <a href="https://www.bhf.org.uk/informationsupport/support/healthy-living/healthy-eating">heart disease</a>, and <a href="https://www.cancerresearchuk.org/about-cancer/causes-of-cancer/diet-and-cancer/does-having-a-healthy-diet-reduce-my-risk-of-cancer">many cancers</a> – as well being more <a href="https://www.bda.uk.com/static/539e2268-7991-4d24-b9ee867c1b2808fc/a1283104-a0dd-476b-bda723452ae93870/one%20blue%20dot%20reference%20guide.pdf">environmentally sustainable</a>.</p> <p>But if you have a penchant for ham sandwiches, rest assured you can continue to indulge as an occasional treat. It’s your overall lifestyle and diet that really matter for your health and risk of developing type 2 diabetes.<!-- Below is The Conversation's page counter tag.

What’s the difference between ‘strep throat’ and a sore throat? We’re developing a vaccine for one of them

<div class="theconversation-article-body"><em><a href="https://theconversation.com/profiles/kim-davis-1535254">Kim Davis</a>, <a href="https://theconversation.com/institutions/murdoch-childrens-research-institute-1027">Murdoch Children's Research Institute</a>; <a href="https://theconversation.com/profiles/alma-fulurija-1535255">Alma Fulurija</a>, <a href="https://theconversation.com/institutions/telethon-kids-institute-1608">Telethon Kids Institute</a>, and <a href="https://theconversation.com/profiles/myra-hardy-1535253">Myra Hardy</a>, <a href="https://theconversation.com/institutions/murdoch-childrens-research-institute-1027">Murdoch Children's Research Institute</a></em></p> <p>the time of the year for coughs, colds and sore throats. So you might have heard people talk about having a “strep throat”.</p> <p>But what is that? Is it just a bad sore throat that goes away by itself in a day or two? Should you be worried?</p> <p>Here’s what we know about the similarities and differences between strep throat and a sore throat, and why they matter.</p> <h2>How are they similar?</h2> <p>It’s difficult to tell the difference between a sore throat and strep throat as they look and feel similar.</p> <p>People usually have a fever, a bright red throat and sometimes painful lumps in the neck (swollen lymph nodes). A throat swab can help diagnose strep throat, but the results can take a few days.</p> <p>Thankfully, both types of sore throat usually get better <a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC8655103/">by themselves</a>.</p> <h2>How are they different?</h2> <p>Most sore throats are caused by viruses such as common cold viruses, the flu (influenza virus), or the virus that causes glandular fever (Epstein-Barr virus).</p> <p>These viral sore throats can occur at any age. Antibiotics don’t work against viruses so if you have a viral sore throat, you won’t get better faster if you take antibiotics.

How holidaying in developing countries affects local inequality

<div class="theconversation-article-body"><em><a href="https://theconversation.com/profiles/alexander-tziamalis-333272">Alexander Tziamalis</a>, <a href="https://theconversation.com/institutions/sheffield-hallam-university-846">Sheffield Hallam University</a> and <a href="https://theconversation.com/profiles/yuan-wang-1360783">Yuan Wang</a>, <a href="https://theconversation.com/institutions/sheffield-hallam-university-846">Sheffield Hallam University</a></em></p> <p>A few years ago, one of us (Alex) went for a vacation to the Dominican Republic. The motivation was similar to millions of other tourists every year: escape the daily routine, enjoy the sun and beaches, and gather some strength to face another cold winter.</p> <p>Unfortunately, a few things weren’t very conducive to a happy break. The staff at the mammoth hotel were making as little as US$1 (£0.79) for a 12-hour shift. Worse, most of them lived in a shanty town nearby. They had no sewers and no reliable electricity.</p> <p>The hotel also exploited its power over local farmers to procure food exceedingly cheaply. Schools were overcrowded and many children dropped out to work in businesses like these hotels and farms, perpetuating the cycle.</p> <p>This anecdotal picture is corroborated by the country’s economic data. Despite <a href="https://data.worldbank.org/indicator/NY.GDP.MKTP.KD.ZG?locations=DO">GDP growth</a> frequently above 5% each year, the Dominican Republic suffers from <a href="https://dominicantoday.com/dr/local/2023/02/17/dominican-republic-shows-a-high-level-of-economic-inequality-in-latin-america-and-the-caribbean/">substantial inequality</a>. The wealthiest 1% capture 30% of all income, compared to 18% in the US.</p> <p>But how bad is tourism for inequality in developing countries overall? <a href="https://shura.shu.ac.uk/31942/">Our recent research</a> has sought to answer this, looking at 71 countries around the world. The picture is complicated, but the overall results are not as bleak as you might fear.</p> <h2>Upsides and downsides</h2> <p>Clearly there are pros and cons to tourism. It makes holidaymakers happy while bringing people closer and promoting awareness of other cultures. It empowers communities and provides disadvantaged groups with opportunities, from the local artisan who can sell directly to customers, to women <a href="https://blogs.worldbank.org/psd/empowering-women-through-tourism-0">who would otherwise</a> be struggling to find work.</p> <p>Tourism sustains a lot of jobs and economic value overall, making it attractive to governments as a way of boosting growth. In 2019 there were a whopping <a href="https://www.statista.com/statistics/209334/total-number-of-international-tourist-arrivals/#:%7E:text=Despite%20the%20significant%20annual%20increase,lowest%20figure%20recorded%20since%201989">1.5 billion</a> international tourist arrivals around the world. They were serviced by <a href="https://www.statista.com/statistics/1268465/number-of-travel-and-tourism-jobs-worldwide/#:%7E:text=Despite%20the%20increase%2C%20the%20number,to%20320%20million%20in%202023.">nearly 300 million</a> travel and tourism workers, and the sector generated <a href="https://wttc.org/research/economic-impact#:%7E:text=In%202022%2C%20the%20Travel%20%26%20Tourism,%2C%20only%2014.1%25%20below%202019.">over 7%</a> of global GDP.</p> <p>On the other hand, tourism can <a href="https://www.theworldcounts.com/challenges/consumption/transport-and-tourism/negative-environmental-impacts-of-tourism">degrade the environment</a>. Witness the Inca citadel of Machu Picchu in the Peruvian Andes needing to <a href="https://www.machupicchutrek.net/how-many-tourists-visit-machu-picchu-annually/">restrict</a> the number of visitors, for instance, because the site was <a href="https://storymaps.arcgis.com/stories/d2f4fc1c7b314cc8a6c8af466cec0d24">getting damaged</a>.</p> <p>Equally, <a href="https://www.itmustbenow.com/feature/our-big-questions/exploitation-travel-tourism/">tourism is associated</a> with other <a href="https://www.cntraveler.com/galleries/2015-06-19/barcelona-bhutan-places-that-limit-tourist-numbers">knock-on effects</a> such as water scarcity, pollution, crime, sex exploitation and destroying tradition.</p> <p>But what about inequality? The tourism industry <a href="https://www.itmustbenow.com/feature/our-big-questions/exploitation-travel-tourism/">is frequently associated</a> with ridiculously low wages, long hours without a break, and unhealthy conditions for live-in staff. Dedicated trade unions often don’t exist, or they’re underpowered and cannot effectively protect workers.</p> <p>Tourism can also distort the economy. <a href="https://www.theguardian.com/technology/2022/aug/10/i-wanted-my-children-to-grow-up-here-how-airbnb-is-ruining-local-communities-in-north-wales">In the UK</a> for example, communities in many popular tourist destinations cannot afford to buy a home anymore.</p> <p>Yet when you look at how tourism affects equality overall, the existing academic literature shows conflicting results. A number of studies <a href="https://www.sciencedirect.com/science/article/abs/pii/S0160738316301281#:%7E:text=Findings%20confirm%20that%20tourism%20increases%20income%20inequality%20in%20developing%20economies.&amp;text=The%20squared%20tourism%20revenue%20has%20a%20significant%20negative%20impact%20on%20income%20inequality.&amp;text=Findings%20confirm%20the%20presence%20of%20Kuznets%20curve%20hypothesis.">find that</a> it worsens income inequality, while others <a href="https://journals.sagepub.com/doi/abs/10.1177/0047287520954538">find the opposite</a>.</p> <p>If you were wondering about the Dominican Republic, there’s <a href="https://journals.sagepub.com/doi/abs/10.1177/0047287518789272#:%7E:text=The%20results%20showed%20that%20income,in%20the%20distribution%20of%20wealth.">a study</a> showing that tourism actually has a negligible impact on inequality.</p> <h2>Our findings</h2> <p>Ours is the first study to <a href="https://journals.sagepub.com/doi/10.1177/13548166231177106">look at the effect</a> of a few potential determining factors to try and gain a deeper understanding of the relationship between tourism and equality. These factors include the country’s level of economic and financial development, inflation rate and government policies seeking to redistribute wealth.</p> <p>Our dataset spans from 1996–2016. We would have ideally looked at even more than 71 countries, but others had to be excluded because good-quality data was unavailable.</p> <p>We found that tourism eased income inequality in lower income countries when it went hand in hand with redistributive policies. <a href="https://webcache.googleusercontent.com/search?q=cache:6nbn68M3_toJ:https://dailynews.co.tz/how-tz-could-attract-more-tourists/&amp;cd=8&amp;hl=en&amp;ct=clnk&amp;gl=uk">Tanzania, for example,</a> gets 17% of its GDP from tourism. This has enabled the country to <a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC8121963/">significantly increase</a> its spending on health, education and infrastructure.</p> <p>In wealthier countries, the opposite was counterintuitively the case: increasing tourism exacerbated inequality when combined with redistributive policies.</p> <p>It may be that in places where education and infrastructure are already at high levels, improving them has less effect on inequality. Or it may be that improving the welfare system reduces workers’ incentive to upskill and seek better paid jobs in other sectors. These possibilities need further investigation.</p> <p>Our analysis also highlighted the importance of financial opportunities such as broad access to bank credit. All countries with more inclusive financial systems comparatively reduced inequality when they brought in more tourists.</p> <p>It might be that financial access enables a broader cross-section of entrepreneurs to set up or expand tourist businesses, with knock-on benefits to their communities. This is bad news for developing countries like India, Brazil South Africa and Barbados, where <a href="https://www.worldbank.org/en/news/press-release/2015/09/14/long-term-finance-shortage-post-2008-crisis-blunts-progress-in-developing-countries">it’s difficult</a> to obtain long-term loan, which usually come with onerous terms.</p> <p>Having said that, the benefits from financial access were more marked in developed countries. In such countries, it may be that this galvanises proportionately more entrepreneurs because they are not being held back to the same extent by other problems like corruption and poor education.</p> <p>When we looked at the effect of inflation, it worsened inequality in richer countries <a href="https://www.niesr.ac.uk/blog/unequal-impact-rising-inflation">like the UK</a> as tourism increases. We suspect that when inflation takes off in wealthier countries, it’s more difficult for tourism workers to renegotiate their wages quickly because employment contracts are more formal.</p> <p>Equally, poorer countries are often more used to higher inflation, so workers may be more adept at such negotiations.</p> <p>So overall, it’s not possible to say that increasing tourism widens or reduces inequality – it very much depends on other factors. But clearly tourism can be good news for inequality in poorer countries when it’s combined with redistributive policies and financial inclusion.</p> <p>This certainly won’t solve problems like worker exploitation across the board, but it does mean that holidaying in developing countries will often be helping them to become more equal over time.<!-- Below is The Conversation's page counter tag.

Disturbing development in Matthew Perry's death

<p>An investigation into Matthew Perry's death is rounding out, and authorities reportedly believe that  "multiple people" should be charged for his untimely death.</p> <p>The <em>Friends </em>star was found dead eight months ago at the age of 54, in the hot tub of his Los Angeles home, with an autopsy revealing that he had died from the "acute effects of ketamine". </p> <p>A police source has told  <em>People </em>that investigation into the star's death is "nearing its conclusion". </p> <p>“A law enforcement investigative source (says the) investigation into Matthew Perry’s ketamine death is ‘nearing its conclusion’ and police believe ‘multiple people’ should be charged,” the source told People</p> <p>“The source says the US Attorney’s Office will make the ultimate decision on whether or not to press charges.”</p> <p>It is understood that Perry was undergoing ketamine infusion therapy to treat anxiety and depression at the time. </p> <p>The autopsy noted that the levels of Ketamine in Perry's system were in the same range for surgical general anaesthesia, which prompted the LAPD to investigate how he received the drug. </p> <p>The LAPD has been working on its investigation since December in conjunction with Drug Enforcement Administration (DEA) and the U.S Postal Inspector. </p> <p>“Law enforcement sources tell us there is an ongoing investigation into where Matthew got the ketamine that ended up playing a part in his death - and the main questions are who provided the drug, and under what circumstances,” TMZ reported at the time.</p> <p>“We do know they’ve already interviewed some key people in Hollywood.</p> <p>“While our sources could not provide names they told us investigators have approached and spoken to people who are known to have a history of drug use or abuse.</p> <p>“We’re told those people are not necessarily the actual source of ketamine, but they could have information leading to the source.”</p> <p>Drowning, coronary artery disease and  buprenorphine effects were also listed as other contributing factors in his passing.</p> <p><em>Image: Warner Bros Tv/Bright/Kauffman/Crane Pro/Koba/ Shutterstock Editorial</em></p> <p> </p>

New development in Samantha Murphy murder case

<p>In a significant turn of events, Patrick Stephenson, the man charged with the murder of Samantha Murphy, has secured high-profile legal representation. Samantha Murphy, a beloved mother of three, disappeared after going for a run on Sunday, February 4. Despite extensive searches near her home in Ballarat, her body has not been found.</p> <p>Patrick Orren Stephenson, 22, was charged with the 51-year-old’s murder in March. He has now enlisted the services of renowned solicitor Paul Galbally from Melbourne law firm Galbally O’Bryan.</p> <p>Galbally is recognised for his expertise in handling some of the country’s largest and most intricate criminal cases, with previous clients including the late Catholic Cardinal George Pell, who was initially convicted but later acquitted of historic child sex charges.</p> <p>In a major breakthrough in the investigation, <a href="https://www.oversixty.com.au/finance/legal/major-update-in-search-for-samantha-murphy-s-body" target="_blank" rel="noopener">police discovered Samantha Murphy’s missing phone</a> last Wednesday. The phone, found in a dam about 19km south of the Murphy family home, is in near-perfect condition despite being submerged in mud. Forensic testing on the phone is ongoing and could provide crucial information about her final movements.</p> <p>Samantha's husband, Mick, confirmed the phone belonged to his wife immediately upon being informed by the police. The recovery of the phone was a moment of subdued celebration for the officers, with footage from the ABC showing them hugging and shaking hands at the discovery site.</p> <p>Cybersecurity expert Nigel Phair called the phone’s recovery a “game changer” for the investigation. “The physical properties of the phone will obviously be damaged," he said. "But what’s behind it, those ones and zeros of data, will be retrievable.” </p> <p>Samantha Murphy was last seen leaving her Eureka Street home in Ballarat at around 7 am for a 14km run through the Woowookarung Regional Park. Police believe she reached the Mount Clear area, adjacent to the park, about an hour after leaving home. Subsequent searches by police and volunteers have yet to locate any trace of her.</p> <p>In February, a large group of volunteers gathered at Ballarat’s Eureka Stockade Memorial Park to search the surrounding bushland, using metal detectors and even a sniffer dog. Later, police conducted a targeted search of Buninyong Bushland Reserve, employing specialist units including mounted officers, the dog squad and motorcyclists. This search was driven by intelligence from multiple sources.</p> <p>Patrick Stephenson, who has not yet entered a plea, is scheduled to appear at Ballarat Magistrates’ Court on August 8, facing charges of Samantha Murphy’s murder. The case continues to unfold as investigators hope the data recovered from Samantha's phone will provide new leads and bring them closer to solving this tragic mystery.</p> <p><em>Images: Supplied / Facebook</em></p>

Yes, adults can develop food allergies. Here are 4 types you need to know about

<div class="theconversation-article-body"><em><a href="https://theconversation.com/profiles/clare-collins-7316">Clare Collins</a>, <a href="https://theconversation.com/institutions/university-of-newcastle-1060">University of Newcastle</a></em></p> <p>If you didn’t have food allergies as a child, is it possible to develop them as an adult? The short answer is yes. But the reasons why are much more complicated.</p> <p>Preschoolers are about <a href="https://pubmed.ncbi.nlm.nih.gov/25316115/">four times more likely to have a food allergy</a> than adults and are more likely to grow out of it as they get older.</p> <p>It’s hard to get accurate figures on adult food allergy prevalence. The Australian National Allergy Council reports <a href="https://nationalallergycouncil.org.au/about-us/our-strategy">one in 50 adults</a> have food allergies. But a US survey suggested as many as <a href="https://pubmed.ncbi.nlm.nih.gov/30646188/">one in ten adults</a> were allergic to at least one food, with some developing allergies in adulthood.</p> <h2>What is a food allergy</h2> <p><a href="https://pubmed.ncbi.nlm.nih.gov/36509408/">Food allergies</a> are immune reactions involving <a href="https://www.aaaai.org/tools-for-the-public/allergy,-asthma-immunology-glossary/immunoglobulin-e-(ige)-defined">immunoglobulin E (IgE)</a> – an antibody that’s central to triggering allergic responses. These are known as “IgE-mediated food allergies”.</p> <p>Food allergy symptoms that are <em>not</em> mediated by IgE are usually delayed reactions and called <a href="https://pubmed.ncbi.nlm.nih.gov/25316115/">food intolerances or hypersensitivity</a>.</p> <p>Food allergy symptoms can include hives, swelling, difficulty swallowing, vomiting, throat or chest tightening, trouble breathing, chest pain, rapid heart rate, dizziness, low blood pressure or <a href="https://www.allergy.org.au/hp/papers/acute-management-of-anaphylaxis-guidelines?highlight=WyJhbmFwaHlsYXhpcyJd">anaphylaxis</a>.</p> <p>IgE-mediated food allergies can be life threatening, so all adults need an <a href="https://allergyfacts.org.au/allergy-management/newly-diagnosed/action-plan-essentials">action management plan</a> developed in consultation with their medical team.</p> <p>Here are four IgE-mediated food allergies that can occur in adults – from relatively common ones to rare allergies you’ve probably never heard of.</p> <h2>1. Single food allergies</h2> <p>The most <a href="https://pubmed.ncbi.nlm.nih.gov/30646188/">common IgE-mediated food allergies</a> in adults in a US survey were to:</p> <ul> <li>shellfish (2.9%)</li> <li>cow’s milk (1.9%)</li> <li>peanut (1.8%)</li> <li>tree nuts (1.2%)</li> <li>fin fish (0.9%) like barramundi, snapper, salmon, cod and perch.</li> </ul> <p>In these adults, about 45% reported reacting to multiple foods.</p> <p>This compares to <a href="https://pubmed.ncbi.nlm.nih.gov/25316115/">most common childhood food allergies</a>: cow’s milk, egg, peanut and soy.</p> <p>Overall, adult food allergy prevalence appears to be increasing. Compared to <a href="https://pubmed.ncbi.nlm.nih.gov/14657884/">older surveys published in 2003</a> and <a href="https://pubmed.ncbi.nlm.nih.gov/15241360/">2004</a>, peanut allergy prevalence has increased about three-fold (from 0.6%), while tree nuts and fin fish roughly doubled (from 0.5% each), with shellfish similar (2.5%).</p> <p>While new <a href="https://pubmed.ncbi.nlm.nih.gov/38214821/">adult-onset food allergies are increasing</a>, childhood-onset food allergies are also more likely to be retained into adulthood. Possible reasons for both <a href="https://pubmed.ncbi.nlm.nih.gov/38214821/">include</a> low vitamin D status, lack of immune system challenges due to being overly “clean”, heightened sensitisation due to allergen avoidance, and more frequent antibiotic use.</p> <h2>2. Tick-meat allergy</h2> <p>Tick-meat allergy, also called α-Gal syndrome or mammalian meat allergy, is an allergic reaction to galactose-alpha-1,3-galactose, or α-Gal for short.</p> <p><a href="https://pubmed.ncbi.nlm.nih.gov/33529984/">Australian immunologists first reported</a> links between α-Gal syndrome and tick bites in 2009, with cases also reported in the United States, Japan, Europe and South Africa. The <a href="https://pubmed.ncbi.nlm.nih.gov/38318181/">US Centers for Disease Control estimates</a> about 450,000 Americans <a href="https://www.cdc.gov/mmwr/volumes/72/wr/mm7230a2.htm">could be affected</a>.</p> <p>The α-Gal contains a carbohydrate molecule that is bound to a <a href="https://pubmed.ncbi.nlm.nih.gov/38318181/">protein</a> molecule in <a href="https://alphagalinformation.org/what-is-a-mammal/">mammals</a>.</p> <p>The IgE-mediated allergy is triggered after repeated bites from ticks or <a href="https://www.insectshield.com/pages/chiggers">chigger mites</a> that have bitten those mammals. When tick saliva crosses into your body through the bite, antibodies to α-Gal are produced.</p> <p>When you subsequently eat foods that contain α-Gal, the allergy is triggered. These triggering foods include meat (lamb, beef, pork, rabbit, kangaroo), dairy products (yoghurt, cheese, ice-cream, cream), <a href="https://en.wikipedia.org/wiki/Gelatin">animal-origin gelatin</a> added to gummy foods (jelly, lollies, marshmallow), prescription medications and over-the counter supplements containing gelatin (<a href="https://www.drugs.com/inactive/gelatin-57.html">some antibiotics, vitamins and other supplements</a>).</p> <p>Tick-meat allergy reactions can be hard to recognise because they’re usually delayed, and they can be severe and include anaphylaxis. Allergy <a href="https://www.allergy.org.au/patients/food-allergy/mammalian-meat-tick-faq">organisations produce management guidelines</a>, so always discuss management with your doctor.</p> <h2>3. Fruit-pollen allergy</h2> <p>Fruit-pollen allergy, called pollen food allergy syndrome, is an <a href="https://pubmed.ncbi.nlm.nih.gov/38002141/">IgE-mediated allergic reaction</a>.</p> <p>In susceptible adults, pollen in the air provokes the production of IgE antibodies to antigens in the pollen, but these antigens are similar to ones found in some fruits, vegetables and herbs. The problem is that <a href="https://pubmed.ncbi.nlm.nih.gov/38002141/">eating those plants</a> triggers an allergic reaction.</p> <p>The <a href="https://pubmed.ncbi.nlm.nih.gov/38002141/">most allergenic tree pollens</a> are from birch, cypress, Japanese cedar, <a href="https://www.betterhealth.vic.gov.au/health/conditionsandtreatments/latex-allergy">latex</a>, grass, and ragweed. Their pollen can cross-react with <a href="https://pubmed.ncbi.nlm.nih.gov/38002141/">fruit and vegetables</a>, including kiwi, banana, mango, avocado, grapes, celery, carrot and potato, and some herbs such as caraway, coriander, fennel, pepper and paprika.</p> <p>Fruit-pollen allergy is not common. Prevalence <a href="https://pubmed.ncbi.nlm.nih.gov/38002141/">estimates are between 0.03% and 8%</a> depending on the country, but it can be life-threatening. Reactions range from itching or tingling of lips, mouth, tongue and throat, called <a href="https://pubmed.ncbi.nlm.nih.gov/20306812/">oral allergy syndrome</a>, to mild <a href="https://www.allergy.org.au/patients/skin-allergy/urticaria-hives">hives</a>, to anaphylaxis.</p> <h2>4. Food-dependent, exercise-induced food allergy</h2> <p>During heavy exercise, the stomach produces less acid than usual and gut permeability increases, meaning that small molecules in your gut are more likely to escape across the membrane into your blood. These include food molecules that trigger an IgE reaction.</p> <p>If the person already has IgE antibodies to the foods eaten before exercise, then the risk of triggering food allergy reactions is increased. This allergy is called <a href="https://pubmed.ncbi.nlm.nih.gov/37893663/">food-dependent exercise-induced allergy</a>, with symptoms ranging from hives and swelling, to difficulty breathing and anaphylaxis.</p> <p><a href="https://pubmed.ncbi.nlm.nih.gov/30601082/">Common trigger foods include</a> wheat, seafood, meat, poultry, egg, milk, nuts, grapes, celery and other foods, which could have been eaten many hours before exercising.</p> <p>To complicate things even further, allergic <a href="https://pubmed.ncbi.nlm.nih.gov/33181008/">reactions can</a> occur at lower levels of trigger-food exposure, and be more severe if the person is simultaneously taking non-steroidal inflammatory medications like aspirin, drinking alcohol or is sleep-deprived.</p> <p>Food-dependent exercise-induced allergy is extremely rare. Surveys have estimated prevalence as between <a href="https://www.sciencedirect.com/science/article/pii/S1555415517300259">one to 17 cases per 1,000 people worldwide</a> with the highest prevalence between the teenage years to age 35. Those affected often have other allergic conditions such as hay fever, asthma, allergic conjunctivitis and dermatitis.</p> <h2>Allergies are a growing burden</h2> <p>The <a href="https://pubmed.ncbi.nlm.nih.gov/36509408/">burden on physical health, psychological health</a> and health costs due to food allergy is increasing. In the US, this <a href="https://pubmed.ncbi.nlm.nih.gov/38393624/">financial burden was estimated as $24 billion per year</a>.</p> <p>Adult food allergy needs to be taken seriously and those with severe symptoms should wear a medical information bracelet or chain and carry an <a href="https://www.healthdirect.gov.au/how-to-use-an-adrenaline-autoinjector-epipen-anapen">adrenaline auto-injector pen</a>. Concerningly, surveys suggest only <a href="https://pubmed.ncbi.nlm.nih.gov/30646188/">about one in four adults</a> with food allergy have an adrenaline pen.</p> <p>If you have an IgE-mediated food allergy, discuss your management plan with your doctor.

Princess of Wales and King Charles: one in two people develop cancer during their lives – the diseases and treatments explained

<p><em><a href="https://theconversation.com/profiles/gavin-metcalf-1340598">Gavin Metcalf</a>, <a href="https://theconversation.com/institutions/anglia-ruskin-university-1887">Anglia Ruskin University</a></em></p> <p>The Princess of Wales released a <a href="https://x.com/KensingtonRoyal/status/1771235267837321694?s=20">moving video message</a> on March 22 to address speculation about her health. In it, the future queen disclosed that she’d been <a href="https://www.bbc.co.uk/news/health-68641710">diagnosed with cancer</a> following tests conducted after she underwent major abdominal surgery at a clinic in London in January.</p> <p>Catherine explained that she was undergoing “preventative chemotherapy” – but emphasised that her surgery had been successful, and that she was “well” and “getting stronger every day”.</p> <p>The message was the <a href="https://www.theguardian.com/uk-news/2024/mar/22/princess-kate-cancer-royal-family-health-annus-horribilis">second announcement</a> of a royal family cancer diagnosis in recent weeks. On February 5, Buckingham Palace <a href="https://www.royal.uk/a-statement-from-buckingham-palace-5Feb24">published a statement</a> that King Charles III had been diagnosed with an undisclosed form of <a href="https://www.bbc.co.uk/news/uk-68208157">cancer, unrelated</a> to the treatment he had been receiving for an enlarged prostate.</p> <figure><iframe src="https://www.youtube.com/embed/3xzKooCaRXU?wmode=transparent&amp;start=0" width="440" height="260" frameborder="0" allowfullscreen="allowfullscreen"></iframe></figure> <p>The statement said that he had begun “regular treatments”. The king postponed all public-facing duties during his treatment, but <a href="https://www.bbc.co.uk/news/uk-68213383">reportedly continued</a> with his “constitutional role as head of state, including completing paperwork and holding private meetings”.</p> <p>Cancer is the <a href="https://www.who.int/news-room/fact-sheets/detail/cancer">leading cause of death</a> worldwide. <a href="https://www.nhs.uk/conditions/cancer/#:%7E:text=The%20cancerous%20cells%20can%20invade,of%20cancer%20during%20their%20lifetime.">One in two</a> people will develop some form of cancer in their lifetime – so the condition will affect almost every family. However, many cancers can be cured if, as appears to be the case with the king, the condition is <a href="https://www.bbc.co.uk/news/uk-68213383">detected early</a> and treated effectively.</p> <h2>What is cancer?</h2> <p>Our bodies are made up of more than 100 billion cells, and cancer typically starts with changes in a small group of cells – or even a single one.</p> <p>We have different cell types depending upon where in the body they are and the function that the cell has. The size, amount and function of each of these cells is normally tightly regulated by genes – groups of codes held within our DNA – that instruct cells how to grow and divide.</p> <p>However, changes (mutations) to DNA can alter the way cells grow and multiply – often forming a lump, or solid tumour. Cancers can also develop in blood cells, such as white blood cell cancer which is known as leukaemia. This type of cancer does not form solid tumours; instead, the cancer builds up in the blood or sometimes the marrow in the core of bones, where blood cells are produced.</p> <p>In all, there are <a href="https://www.cancerresearchuk.org/about-cancer/what-is-cancer/how-cancer-starts/types-of-cancer#:%7E:text=For%20example%2C%20nerves%20and%20muscles,of%20cell%20they%20start%20in.">more than 200</a> types of cancer, but all start with mutations in the DNA contained within each and every cell.</p> <h2>What exactly are mutations?</h2> <p>Think of your DNA as a big recipe book, and your genes as individual recipes for making different dishes. Mutations are smudges or missing words from this recipe that can result in key ingredients not being added into the mix.</p> <figure><iframe src="https://www.youtube.com/embed/8BJ8_5Gyhg8?wmode=transparent&amp;start=0" width="440" height="260" frameborder="0" allowfullscreen="allowfullscreen"></iframe></figure> <p>Regardless of the type of cancer or the cells from which it develops, mutations in our genes can result in a cell no longer understanding its instructions.</p> <p>These mutations can happen by chance when dividing, but can also be the result of lifestyle choices such as <a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC6141049/">smoking</a>, <a href="https://www.ndph.ox.ac.uk/news/new-genetic-study-confirms-that-alcohol-is-a-direct-cause-of-cancer#:%7E:text=These%20mutations%20both%20disrupt%20the,aldehyde%20dehydrogenase%202%20(ALDH2).">drinking</a>, and <a href="https://www.cancer.gov/about-cancer/causes-prevention/risk/obesity/physical-activity-fact-sheet">inactivity</a>.</p> <p>Research has found that in order for a normal cell to turn into a cancerous cell, anywhere from <a href="https://www.sanger.ac.uk/news_item/1-10-mutations-are-needed-drive-cancer-scientists-find/">one to ten different mutations</a> are normally required.</p> <h2>How is cancer treated?</h2> <p>Treatment options for cancer depend on a variety of factors, including where your cancer is, how large it is, and whether it has spread to other parts of the body. The main treatments for cancer include surgery, chemotherapy, and radiotherapy.</p> <p>Chemotherapy uses drugs to target and kill cells that are rapidly dividing in our bodies. This approach is effective at targeting fast-growing cells in various cancers – but also has negative side effects. It also targets healthy cells that rapidly divide, such as hair and the cells lining our digestive system. This can lead to commonly reported <a href="https://www.nhs.uk/conditions/chemotherapy/side-effects/">side-effects</a> such as hair loss, nausea and diarrhoea.</p> <p><a href="https://www.cancerresearchuk.org/about-cancer/treatment/chemotherapy?gad_source=1&amp;gclid=Cj0KCQjw-_mvBhDwARIsAA-Q0Q6tyQxTuBzU7vVD7SHjQ5dF-fRdqnL7S74-k5LXyTqODydsrPfJVsoaAkgyEALw_wcB&amp;gclsrc=aw.ds">Chemotherapy</a> can be used both preventatively – as in the case of the princess – and therapeutically.</p> <figure><iframe src="https://www.youtube.com/embed/FkZn5u3MIiY?wmode=transparent&amp;start=0" width="440" height="260" frameborder="0" allowfullscreen="allowfullscreen"></iframe></figure> <p>Preventative chemotherapy, also known as <a href="https://www.cancer.gov/publications/dictionaries/cancer-terms/def/adjuvant-therapy">adjuvant chemotherapy</a>, is given after surgery or other primary treatments to eliminate any remaining cancer cells in the body. It aims to reduce the risk of the cancer returning (known as recurrence).</p> <p>Therapeutic chemotherapy is used as a treatment option for cancer that has spread or is well established, such as advanced-stage cancers.</p> <p><a href="https://www.cancerresearchuk.org/about-cancer/treatment/surgery/about">Surgery</a> involves the physical removal of cancerous tissues as well as nearby lymph nodes – small glands which act as filters in your body that cancers can spread through – to eliminate the tumour. Surgery is often used to remove localised cancers that haven’t spread throughout the body.</p> <p><a href="https://www.cancerresearchuk.org/about-cancer/treatment/radiotherapy">Radiotherapy</a> uses high-energy radiation beams that are able to target specific areas where tumour cells are located to destroy or shrink the tumour. Radiotherapy can be applied externally or internally.</p> <p>Chemotherapy, surgery, and radiotherapy are often combined in cancer treatment to improve outcomes for patients.</p> <p>Thanks to developments in cancer research over the last 50 years, survival rates have improved greatly – although the rate of improvement has <a href="https://news.cancerresearchuk.org/2024/02/02/world-cancer-day-2024/#:%7E:text=Improvements%20in%20cancer%20survival%20have%20slowed%20in%20recent%20years&amp;text=Survival%20increased%20three%20to%20five,consistently%20lags%20behind%20comparable%20countries.">slowed recently</a>. Cancer survival depends on various factors such as age – people under 40 have a <a href="https://www.cancer.gov/about-cancer/causes-prevention/risk/age">greater chance</a> of survival – overall health and fitness, as well as family history.</p> <h2>What you should do</h2> <p>Particular changes in your body or warning symptoms could indicate the presence of cancer. These include, but are not limited to:</p> <ul> <li>Unexplained weight loss;</li> <li>Fatigue that doesn’t improve with rest;</li> <li>Changes in bowel or bladder habits;</li> <li>Persistent cough or coughing up blood;</li> <li>Difficulty swallowing;</li> <li>Persistent pain;</li> <li>Noticing lumps, such as in a breast or testicle.</li> </ul> <p>The symptoms may not necessarily be the result of cancer. But it is important to get checked by a doctor if you notice anything out of the ordinary or have had persistent symptoms that don’t ease. Early detection and treatment can <a href="https://www.science.org/doi/full/10.1126/science.aay9040">significantly improve</a> outcomes for many types of cancer.<!-- Below is The Conversation's page counter tag.

Major development in Madeleine McCann case

<p>In the ongoing investigation into the disappearance of Madeleine McCann, German police have descended upon a property in Braunschweig, Germany, in search of a key associate of Christian Brueckner, the prime suspect in the case.</p> <p>The urgency of the search stems from the belief that this individual may possess crucial information regarding the fate of the missing girl.</p> <p>The focus of this operation was a residence linked to a 56-year-old man identified only as Ralph H. According to reports from <a href="https://www.thesun.co.uk/news/26665050/hunt-madeleine-mccann-christian-b-pal/" target="_blank" rel="noopener"><em>The Sun</em></a>, Ralph H. is a long-time friend of Brueckner, suspected of being involved in criminal activities alongside him, including home robberies.</p> <p>The property, located just outside Braunschweig, was surrounded by armed officers – however, the operation hit a roadblock as police were unable to enter the premises due to the absence of a search warrant. </p> <p>The urgency surrounding Ralph H. is palpable, with authorities stressing the need to speak with him promptly. “We must find him to ask him about missing Madeleine McCann,” said a<span style="font-family: -apple-system, BlinkMacSystemFont, 'Segoe UI', Roboto, Oxygen, Ubuntu, Cantarell, 'Open Sans', 'Helvetica Neue', sans-serif;"> detective from Germany’s federal investigative agency, the Bundeskriminalamt (BKA). </span>“He’s not at home, he doesn’t answer the phone, he’s apparently disappeared.”</p> <p>Neighbours of Ralph H. corroborated reports of his absence: “They surrounded his home and shouted out his name but with no luck,” one said. “The officers later asked me if I had any idea where Ralph could be. It was about midday and I thought he was out working. But it turns out he hasn’t been seen for nearly a week now.” </p> <p>Meanwhile, Christian Brueckner, the main suspect in Madeleine McCann's disappearance, is embroiled in a separate legal battle. Currently facing trial for unrelated sexual offences, Brueckner's defence has maintained his silence, refusing to respond to the charges against him. Despite his denial of involvement in Madeleine's case, suspicions loom large, given his proximity to the scene of her disappearance and his criminal history.</p> <p>As the investigation unfolds, the spotlight remains on individuals like Ralph H. and Brueckner, whose connections and actions may hold the key to unraveling the mystery that has gripped the world for nearly two decades.</p> <p><em>Images: Getty</em></p>

Major development in search for Samantha Murphy

<p>Police are moving to a different search area around 5km away from where Samantha Murphy was last seen, after receiving new information from her mobile data. They now believe that “one or more parties” were involved in her disappearance. </p> <p>The Ballarat mum was last seen leaving her home at 7am on February 4 for her usual morning run. </p> <p>On Friday, detectives from the Missing Persons Squad will lead a targeted search of the Mount Clear area, which is adjacent to the Canadian State Forest where Murphy was known to frequent, as part of their investigation.</p> <p>The search will focus on an area “highlighted by intelligence derived from phone data”.</p> <p>Despite missing for almost three weeks now, police still insist that they did not believe Murphy;'s disappearance was “sinister”, but have now confirmed that she went missing under suspicious circumstances.</p> <p>“Police are treating her disappearance as suspicious due to the length of time she has been missing and given no trace of her has been found,” police said.</p> <p>Detective Acting Superintendent Mark Hatt said that while police are keeping an open mind about what happened to Murphy they have ruled out any type of medical incident as there was nothing to indicate that she left on her own accord. </p> <p>"We are keeping an open mind, but believe the most likely scenario is that her disappearance involves one or more parties," Detective Acting Superintendent Hatt said.</p> <p>“Since Samantha’s disappearance almost three weeks ago, a significant search and investigation has been undertaken in an effort to find her,” he added.</p> <p>“I know that a lot of people, particularly those who live in the local Ballarat community, are extremely concerned about the fact we haven’t yet located Samantha or who may be responsible for her disappearance.</p> <p>“I want to reassure those members of the public that Victoria Police is doing everything we can to find out what has happened and provide some answers to Samantha’s family and the broader community.”</p> <p>Investigators are currently reviewing about 12,000 hours of CCTV footage and following up on over 500 pieces of information. </p> <p>On Thursday, police announced that they have called in additional detectives from <a href="https://www.oversixty.com.au/lifestyle/family-pets/new-development-in-search-for-samantha-murphy" target="_blank" rel="noopener">specialist units</a> to help with the search.</p> <p>They are also asking residents in the Ballarat East and Mount Helen areas particularly around the Canadian Forest to check their CCTV footage for any relevant information. </p> <p>“I encourage anyone who does have information that could be relevant to this investigation — whether that’s a person or vehicle seen in the area on that day, something unusual such as a damaged vehicle or property — to please come forward and speak to police or provide the information via Crime Stoppers,” Hatt said.</p> <p>“Police remain open to any and all possibilities, so if you know something or have seen something, then we want to hear from you.”</p> <p><em>Images: 7NEWs</em></p>

New development in search for Samantha Murphy

<p>Police have called in more than a dozen detectives from specialist units to assist the investigation into the disappearance of Samantha Murphy 18 days after she went missing. </p> <p>The mother-of-three was last seen leaving her Ballarat East home to go on her usual morning run in nearby bushland at around 7am on February 4. </p> <p>Now, The Missing Persons Squad, who is leading the investigation has been expanded to include detectives from the Counter Terrorism Command and Crime Command units.</p> <p>The detectives from these specialist units are “highly skilled” selected for their “experience in complex and protracted investigations”.</p> <p>Police have also clarified that the extra detectives have travelled to Ballarat because of their skills and experience rather than a terror or sex crime link. </p> <p>“We have not taken counter terrorism detectives because we think her disappearance is terrorism related,” police told the <em>Herald Sun</em>. </p> <p>Local community members are also doing whatever they can to help, and are conducting their own searches. </p> <p>The group of volunteers are all working together to find "any answers, any solution, any hints, any evidence that might be able to contribute towards bringing Sam home," local Cristie-Lea King told <em>A Current Affair</em> on Wednesday night. </p> <p>On Wednesday, community-members also banded together to fly in an <a href="https://www.oversixty.com.au/finance/legal/experienced-bush-tracker-to-join-in-search-for-samantha-murphy" target="_blank" rel="noopener">experienced bush tracker </a>to help them and share his expertise ahead of the community-led search on Saturday.</p> <p>“I’m hoping to get a lot done while I’m here,” he told 7News at the time. </p> <p>“I plan on training up some locals in the fundamentals of tracking, so when I leave I can continue to liaise with those on the ground." </p> <p>“People are entitled to their opinions as to whether or not Samantha is out in the bush.</p> <p>“On the chance that she is, I want to ensure that absolutely everything is done to find her.”</p> <p><em>Images: Victoria Police</em></p>

Five tips for developing and managing your budget – even in tough economic times

Many people will start a new year by contemplating how best to budget, plan and save. This is always a good set of aims, but it’s especially important in the inflation-prone and unpredictable economies we’re seeing <a href="https://www.statista.com/statistics/268225/countries-with-the-highest-inflation-rate/">all over Africa and the world</a>.</p> <p>Budgeting is especially key. It is the most effective method to <a href="https://www.thebalancemoney.com/how-to-make-a-budget-1289587">monitor income and expenditure</a>. <a href="https://www.uslendingcompany.com/blog/key-differences-in-writing-a-household-budget-vs-a-personal-budget/">Personal budgets</a> can help you to monitor your resources in pursuit of larger financial goals. Budgeting also offers <a href="https://www.acrwebsite.org/volumes/v46/acr_vol46_2411998.pdf">more opportunities</a> to save money, reduce your debts and live a comfortable life. It can even <a href="https://prucomm.ac.uk/assets/uploads/blog/2013/04/Personal-Budgets-review-of-evidence_FINAL-REPORT.pdf">improve your mental health</a>.</p> <p>But where should you start? What questions do you need to answer in creating a budget? Here are some tips that I’ve learned – not just as an economist, but as a research cost analyst and someone who keeps a budget too.</p> <h2>1. Understand the broader economic conditions</h2> <p>It is imperative that individuals keep themselves aware and up-to-date on the realities of their country’s economic landscape. You don’t have to be a professional economist, but keep an eye on new developments like free business registration, small business development funds and printing of new money notes. What is the current exchange rate? What’s the political landscape and what international factors, like the price of crude oil, are at play? You should also watch the inflation rate and have a sense of unemployment trends.</p> <p>This economic awareness will prepare you to draft your own budget and you’ll have a sense of when external factors mean it’s time to revisit your plans.</p> <h2>2. Review your income sources</h2> <p>The ability to earn income is critical to sustaining livelihoods. Having a definite source of income is the bedrock of budgeting.</p> <p>Some important questions you should ask about your income – and how you might budget with it – include:</p> <ul> <li>What is my current income?</li> <li>What do I use my income for?</li> <li>Am I able to save, given my current income?</li> <li>What proportion of my income do I save and what proportion do I spend?</li> <li>Do I have the capacity to earn more than this?</li> <li>How can I improve my income?</li> </ul> <p>Your answers can help you to identify gaps or untapped potential. Those with irregular or unpredictable income should factor in the element of time-gap in their income, for effective budgeting. Time gap is when they are not earning income. And everyone should make allowance in their budgets for uncertainties like health issues, social engagements, inflation, unemployment, recession and price shocks.</p> <h2>3. Appraise your expenses</h2> <p>Expenses can be broadly categorised into “variable” and “fixed”.</p> <p>Fixed expenses recur within a short period: housing, food, transport, medical costs, electricity, utilities, toiletries and clothing. Variable expenses are more long-term and irregular, such as investment in property or interest-yielding assets, and the purchase of machinery.</p> <p>The main essence of revising our expenses is to analyse and possibly improve our spending habits. In reviewing our expenses, we can consider issues such as:</p> <ul> <li>What is the proportion of consumption-savings ratio from my income? This is how much do I spend compared to how much I save.</li> <li>What are my regular expenses?</li> <li>What are my fixed, capital or investment expenses?</li> <li>What are my extraordinary expenses that need modification?</li> <li>Have there been emergency or extraordinary expenses?</li> </ul> <p>A careful response to the issues raised above offers an occasion to re-evaluate the pattern and direction of our expenses. For instance, overspending, unplanned or extraordinary expenses can be identified. This can lead to an optimal, efficient reallocation of available resources.</p> <h2>4. Stabilise your finances through savings</h2> <p>Savings have been <a href="https://klinglercpa.com/bedrock-principles-for-saving-money/">described</a> as a financial stabiliser, given their potential to cater for urgent needs and create opportunities for investments.</p> <p>Of course, savings have more value when they grow faster than the rate of inflation. Inflation erodes the value of savings. For instance, an amount of 300,000 naira (US$676) saved to purchase an autorickshaw today may be impossible in two months’ time with an inflation rate of 10% when the tricycle price rises to 330,000 naira (US$744). The reverse is the case when there is deflation.</p> <p>Therefore, it is advisable to improve the value of savings through investments in interest-yielding assets such as stocks, shares, bonds, microfinance and production.</p> <p>That’s not to say it’s always easy to save. Many income earners spend as they go, not seeing savings as part of their budgets. Harsh economic realities can also make it difficult – sometimes seemingly impossible – to save. But it’s not impossible: savings can be made in small amounts, through a daily, weekly or monthly contribution to collections, cooperative schemes or microfinance affiliations. For instance, a point of sale business in Nigeria can permit a daily contribution of 500 naira (US$1.13) over 25 work days, giving an average saving of 12,500 naira (US$28.18) per month.</p> <p>The Point-of-Sale business started in Nigeria in 2013 when the Central Bank of Nigeria introduced the agent banking system. A POS agent operates and processes transactions through a POS service provider. Providers of such services include banks, microfinance banks and fintech companies.</p> <h2>5. Run a flexible budget</h2> <p>Once your budget is created, remember that it’s not set in stone. It should be flexible if anything changes in your life. For instance, an amount saved to buy a car can be invested in a promising venture buying shares through public offerings or private placements in multinational organisations like Nestle or Unilever.</p> <p>Also, health emergencies or career advancement programmes can require taking some money out of our savings.</p> <p>In all, budgeting should be flexible enough to incorporate exigencies, especially when catering for the current situation will culminate into a greater good.<!-- Below is The Conversation's page counter tag.

Dad awarded compensation after developing heart issue from mandatory vaccine

<p>An Adelaide father is set to receive hefty compensation after a mandatory Covid jab left him with a debilitating health condition. </p> <p>In 2021 at the height of the Covid pandemic in Australia, 44-year-old Daniel Shepherd was required to receive tow Covid vaccinations, due to his hands on role at an aged care facility. </p> <p>After having two Pfizer vaccines, he suffered some adverse effects, but dismissed his symptoms as nothing serious. </p> <p>In the months after, Shepherd was required to have a booster shot when he began a new job with the Department of Child Protection in October of the same year. </p> <p>In January 2022, the father was told if we wanted to keep his job as a health and childcare worker, he needed to have the jab. </p> <p>After eventually agreeing to the booster, Shepherd has his third dose of Pfizer in late February 2022, but began suffering from chest pains just hours later. </p> <p>"It felt like someone had their knee right on my chest," he told <a href="https://www.9news.com.au/national/adelaide-news-covid-vaccine-man-to-get-government-compensation-after-developing-heart-condition/55cc0fbf-4631-4cf0-b395-8c8b6c71a43f" target="_blank" rel="noreferrer noopener"><em>9News</em>.</a></p> <p>The pain kept getting worse until he was rushed to hospital a few weeks later when he thought he was having a heart attack.</p> <p>There he was diagnosed with post-vaccine pericarditis: an inflammation of the membrane around the heart.</p> <p>His illness meant he was unable to work full time, and also meant he was unable to keep up with his young son.</p> <p>"Even today with just mild exertion [I get] chest pains and then it's followed by fatigue, like severe fatigue," Shepard said.</p> <p>"It's heartbreaking to have to say 'sorry buddy, daddy's tired'." </p> <p>Mr Shepherd decided to take legal action after he was unable to work, launching a workers compensation claim against the government.</p> <p>In a landmark ruling in mid-January, the South Australian Employment Tribunal agreed to pay weekly compensation and medical bills to Shepherd.</p> <p>Doctors were unanimous in his case that the vaccine was the cause of his inability to work, but the government argued emergency directions that were in place at the time trumped the laws around workplace injury.</p> <p>Pericarditis is meant to clear within a few months, but Shepherd's symptoms have plagued him for almost two years.</p> <p><em>Image credits: 9News</em></p>

"These guys have held on": Why a family turned down $50 million for their home

<p>A Sydney family has repeatedly refused to sell their family home to major developers, despite being offered an eight-figure sum for the property. </p> <p>The Zammit family have lived in their impressive home for several decades and have said time and time again that they have no intentions of selling the house, which is situated on a 20,000 square metre parcel of land in western Sydney. </p> <p>With the massive area of land being smack bang in the centre of a major housing development, some realtors have estimated that the property could fetch a price as high as $50 million.</p> <p>Despite the family saying they would be staying in the home, documents obtained by <a href="https://www.news.com.au/finance/real-estate/selling/sydney-familys-home-goes-from-858k-to-50m-as-major-development-crops-up/news-story/eb0bacc20cdae5cad461ff89797cb71d" target="_blank" rel="noopener"><em>news.com.au</em></a> have confirmed that the house was up for sale in both 2015 and and 2016. </p> <p>The house was swiftly taken off the market after being initially listed with a price range $858,000 to $945,000.</p> <p>And just a few years later, they are believed to have received offers of between $33 million and $50 million.</p> <p>The massive property boasts a lush green lawn in stark contrast to all the houses around it and also a huge 200 metre driveway.</p> <p>But just metres away are rows and rows of carbon copy grey houses crammed into tight blocks as part of a major development. </p> <p>The high-density neighbouring homes are built right up to the fence of the Zammit's property, and neighbours reportedly don’t want the owners to sell as they like living in a cul-de-sac.</p> <p>It’s estimated that 50 houses could fit on the Zammit's block of land if they followed the same style as other developer homes in the area. </p> <p>A local real estate agent previously praised the Zammit family for staying put, despite the big payouts they have likely been offered.</p> <p>“The fact that most people sold out years and years ago, these guys have held on. All credit to them,” Ray White Quakers Hill agent Taylor Bredin told <em>7News.</em></p> <p>“Depending on how far you push the development plan, you’d be able to push anywhere from 40 to 50 properties on something like this, and when subdivided, a 300 square metre block would get a million dollars.”</p> <p><em>Image credits: 7News</em></p>

6 step guide to travelling in developing countries

<p>Developing countries are endlessly fascinating and a travel experience not be missed, though you will need to be prepared.</p> <p><strong>1. Do your research</strong></p> <p>In developing countries, it’s rare that you can just buy a plane ticket, arrive and wing it. You’ll need to research destinations, accommodation, transport options and safety in much more depth than you would for your typical holiday spot. This research should continue right up until you depart. The situations in these countries can change overnight, so you want to be up to date with any dangerous incidents or government warnings.</p> <p><strong>2. Learn the local customs</strong></p> <p>A little consideration goes a long way. You don’t want to be the obnoxious tourist who is offending locals without even realising it. As part of your research, look into things like appropriate dress code, cultural conventions around touching or the correct type of language to use. You’ll also need to make some observations during your first few days in a country and ensure you’re behaving in an appropriate way. Remember that you are a guest in their community and should be respectful of their beliefs and customs.</p> <p><strong>3. Be prepared for limited facilities</strong></p> <p>Be prepared for a different level of comfort than you would expect at home or in a first world country. You’ll mostly need to avoid drinking the tap water and the toilets may leave something to be desired. Toiletries can also be hard to come by, so come with your own supply of wet wipes, hand sanitisers or any personal items you need.</p> <p><strong>4. Choose wisely</strong></p> <p>This applies to everything from your choice of hotel to buying a snack on the street. Even if you’ve booked a hotel online, make sure that you check the security features and quality of the room before you commit to spending the night. Do your own research or ask a travel agent about the safest transport options. Many developing countries don’t have the same standards for their airlines or trains as we do. And when you’re choosing a restaurant, find somewhere that looks clean, busy and is well patronised by locals (not just tourists) – they are the best judges of where to eat.</p> <p><strong>5. Beware of begging</strong></p> <p>Poverty can be a big problem in many developing countries, so it’s common to see people begging on the street. It’s tempting to give people money, especially when it’s children. While it might seem that you are helping them, handouts from travellers can create an ongoing culture of begging. Instead, look for a local charitable organisation to donate to or approach a local school or church and see if there are any supplies you can purchase for them.</p> <p><strong>6. Understand bartering and bribery</strong></p> <p>Bartering is a part of life in many developing countries and is expected everywhere from the local market to taxi drivers. Vendors often like to get tourists to play the game and will encourage you to bargain with them, even if you are happy to pay the original price. You don’t want to be ripped off but also remember that while saving a dollar or so means little to you, it can be a big difference to them. You also need to be aware that many of these countries operate on an unofficial system of bribery, so you might be expected to pay a small fee to make a transaction go smoothly. If the amount is small enough, just pay it and move on.</p> <p><strong>7. Register your travel</strong></p> <p>New Zealand government organisation SafeTravel encourages all travellers to register with them, but this is most important if you’re visiting developing countries. In the event of a disaster, communication can become impossible so it is a good idea if the local embassy knows you are in the country. They may be able to provide assistance or just let your family back home know that you are safe. It’s free and only takes a couple of minutes.</p> <p><em>Image credits: Getty Images</em></p>

“We can let you rest now”: Devastating development in missing Nicola Bulley case

<p>Police in the United Kingdom have confirmed that a body found in a cluster of weeds by the River Wyre has been identified as missing mother-of-two Nicola Bulley. </p> <p>Nicola was last seen in St Michael’s on Wyre, Lancashire, just after 9am on January 27. Her body was discovered just over a kilometre from where she disappeared. </p> <p>Nicola was walking her dog along the river after dropping her children off at school when she failed to return. Her mobile phone was found on a bench, still connected to a conference call for work, and her dog - a springer spaniel named Willow - was nearby. </p> <p>“We were called today at 11.36am to reports of a body in the River Wyre, close to Rawcliffe Road," local police reported. "An underwater search team and specialist officers have subsequently attended the scene, entered the water and have sadly recovered a body."</p> <p>Formal identification was required before it could be confirmed that it was Nicola's body, with police announcing the process was complete and the confirmation made at a press conference on Monday. </p> <p>“Sadly, we are now able to confirm that yesterday we recovered Nicola Bulley from the River Wyre,” Lancashire Police's Assistant Chief Constable Peter Lawson said. </p> <p>"Nicola’s family have been informed and are, of course, devastated. Our thoughts are with them at this time, as well as with all her loved ones and the wider community.</p> <p>"We recognise the huge impact that Nicola’s disappearance has had on her family and friends, but also on the people of St Michael’s.</p> <p>"We would like to thank all of those who have helped during what has been a hugely complex and highly emotional investigation.</p> <p>"Today’s development is not the outcome any of us would have wanted, but we hope that it can at least start to provide some answers for Nicola’s loved ones, who remain foremost in our thoughts.”</p> <p>Assistant Chief Constable Lawson added that the case was now being handled by HM Coroner, and that the cause of her death is being treated as unexplained. </p> <p>In the wake of the tragic news breaking, Nicola’s family also issued a statement and emotional tribute for their late loved one. </p> <p>“Finally, Nikki, you are no longer a missing person, you have been found. We can let you rest now,” they said. </p> <p>“We will never be able to comprehend what Nikki had gone through in her last moments and that will never leave us.</p> <p>“We will never forget Nikki - how could we? - she was the centre of our world, she was the one who made our lives so special and nothing will cast a shadow over that.</p> <p>“Our girls will get the support they need from the people who love them the most.”</p> <p><em>Images: Getty </em></p>

Chris Hemsworth’s Alzheimer’s gene doesn’t guarantee he’ll develop dementia

<p>Chris Hemsworth, famous for his role as the god Thor in Marvel Cinematic Universe movies, has announced he will be <a href="https://www.theguardian.com/film/2022/nov/21/chris-hemsworth-to-take-time-off-from-acting-after-discovering-alzheimers-risk" target="_blank" rel="noopener">taking a break</a> from acting after being told he has two copies of the <a href="https://www.nia.nih.gov/news/study-reveals-how-apoe4-gene-may-increase-risk-dementia" target="_blank" rel="noopener">APOE4 gene</a>, increasing his risk of Alzheimer’s.</p> <p>Having one copy of the <a href="https://www.science.org/doi/abs/10.1126/science.8346443" target="_blank" rel="noopener">APOE4 gene</a> increases your risk for Alzheimer’s 2-3 times. Two copies increases your risk 10-15 times.</p> <p>But the key here is “risk”. Having one or more copies of the gene doesn’t guarantee Chris or anyone else in a similar situation will go on to develop Alzheimer’s, the most common form of dementia.</p> <p><strong>Sharing the news</strong></p> <p>Hemsworth’s willingness to share his concerns about developing Alzheimer’s with millions should be applauded. It’s a reminder to all of us to keep an eye on our health and reduce our risk of future illness.</p> <p>Alzheimer’s, and dementia more broadly, is <a href="https://www.dementiastatistics.org/statistics/global-prevalence/" target="_blank" rel="noopener">set to challenge</a> health-care systems worldwide.</p> <p>In Australia alone there are <a href="https://www.dementia.org.au/statistics" target="_blank" rel="noopener">up to</a> 500,000 people with dementia, supported by almost 1.6 million carers. By 2036, about <a href="https://www.dementia.org.au/sites/default/files/NATIONAL/documents/The-economic-cost-of-dementia-in-Australia-2016-to-2056.pdf" target="_blank" rel="noopener">450 people</a> are predicted to be diagnosed daily. So understanding how APOE4 alters the risk for the major cause of dementia may be pivotal in preventing cases.</p> <p>But not all people with the APOE4 gene go on to develop Alzheimer’s. This means that there may be a combination of environmental factors interplaying with the gene that lead some people to develop Alzheimer’s, while others do not.</p> <p><strong>What’s APOE4 got to do with Alzheimer’s?</strong></p> <p>Most Australians have APOE3 or APOE2 genes. In Caucasians it’s only <a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC5531868/" target="_blank" rel="noopener">about 15%</a>, like Hemsworth, who have inherited an APOE4 gene.</p> <p>The APOE gene types are best known for their role in modulating the metabolism of lipids (fats), such as cholesterol and triglycerides.</p> <p>They code for synthesis of different versions of the protein APOE, with subtle differences in structure. The APOE proteins become an integral part of lipoproteins in the blood. These are the fat-carrying particles your GP measures to consider your risk of heart disease.</p> <p>APOE proteins have a similar function in the brain, to modulate lipid levels. But in the context of Alzheimer’s, researchers study it for its effect on the integrity of brain cells.</p> <p>Accumulating evidence <a href="https://www.sciencedirect.com/science/article/pii/S0197458022000550" target="_blank" rel="noopener">suggests</a> APOE4, is associated with brain inflammation and cellular damage.</p> <blockquote class="twitter-tweet"> <p dir="ltr" lang="en">APOE4 is the strongest genetic risk factor for Alzheimer’s disease. A study in <a href="https://twitter.com/Nature?ref_src=twsrc%5Etfw">@Nature</a> establishes a functional link between APOE4, cholesterol, myelination and memory, offering therapeutic opportunities for Alzheimer’s disease. <a href="https://t.co/bNsmDVPfFW">https://t.co/bNsmDVPfFW</a> <a href="https://t.co/58odE1JASl">pic.twitter.com/58odE1JASl</a></p> <p>— Nature Portfolio (@NaturePortfolio) <a href="https://twitter.com/NaturePortfolio/status/1594762841487249410?ref_src=twsrc%5Etfw">November 21, 2022</a></p></blockquote> <p><strong>Can we prevent Alzheimer’s?</strong></p> <p><strong>1. Look after your capillaries</strong></p> <p>Damaged and leaky blood vessels (capillaries) in the brain lead to inflammation, the death of brain cells and cognitive impairment. In fact, in Alzheimer’s, damaged capillaries are the earliest sign of the type of brain damage that causes disease.</p> <p>The protein encoded by the APOE4 gene may be less able to support healthy capillaries in the brain. <a href="https://www.sciencedirect.com/science/article/abs/pii/S0163782709000563" target="_blank" rel="noopener">We suggested</a> APOE4 increases the abundance of specific complexes of lipoproteins and proteins in blood that silently damage brain capillaries, causing them to leak.</p> <p>We also see more brain capillary leakage in mice fed Western-style diets richer in saturated fats.</p> <p>The relationship between how the APOE proteins mediate lipid metabolism and capillary health in humans is poorly understood.</p> <p>But we have 60 years of research knowledge to say with confidence that eating foods good for the heart should also be good for the brain. This is particularly relevant for people with the APOE4 gene.</p> <p>So if you have the APOE4 gene and want to minimise your risk of Alzheimer’s, a healthy diet is a good place to start.</p> <figure class="align-center zoomable"><em><a href="https://images.theconversation.com/files/497142/original/file-20221124-24-rlqyk5.jpg?ixlib=rb-1.1.0&amp;q=45&amp;auto=format&amp;w=1000&amp;fit=clip"><img src="https://images.theconversation.com/files/497142/original/file-20221124-24-rlqyk5.jpg?ixlib=rb-1.1.0&amp;q=45&amp;auto=format&amp;w=754&amp;fit=clip" sizes="(min-width: 1466px) 754px, (max-width: 599px) 100vw, (min-width: 600px) 600px, 237px" srcset="https://images.theconversation.com/files/497142/original/file-20221124-24-rlqyk5.jpg?ixlib=rb-1.1.0&amp;q=45&amp;auto=format&amp;w=600&amp;h=316&amp;fit=crop&amp;dpr=1 600w, https://images.theconversation.com/files/497142/original/file-20221124-24-rlqyk5.jpg?ixlib=rb-1.1.0&amp;q=30&amp;auto=format&amp;w=600&amp;h=316&amp;fit=crop&amp;dpr=2 1200w, https://images.theconversation.com/files/497142/original/file-20221124-24-rlqyk5.jpg?ixlib=rb-1.1.0&amp;q=15&amp;auto=format&amp;w=600&amp;h=316&amp;fit=crop&amp;dpr=3 1800w, https://images.theconversation.com/files/497142/original/file-20221124-24-rlqyk5.jpg?ixlib=rb-1.1.0&amp;q=45&amp;auto=format&amp;w=754&amp;h=397&amp;fit=crop&amp;dpr=1 754w, https://images.theconversation.com/files/497142/original/file-20221124-24-rlqyk5.jpg?ixlib=rb-1.1.0&amp;q=30&amp;auto=format&amp;w=754&amp;h=397&amp;fit=crop&amp;dpr=2 1508w, https://images.theconversation.com/files/497142/original/file-20221124-24-rlqyk5.jpg?ixlib=rb-1.1.0&amp;q=15&amp;auto=format&amp;w=754&amp;h=397&amp;fit=crop&amp;dpr=3 2262w" alt="Capillaries" /></a></em><figcaption><em><span class="caption">Looking after your capillaries with a healthy diet is a good place to start.</span> <span class="attribution"><a class="source" href="https://www.shutterstock.com/image-illustration/system-many-small-capillaries-branch-out-1745173364" target="_blank" rel="noopener">Shutterstock</a></span></em></figcaption></figure> <p><strong>2. Give your brain a break</strong></p> <p>Reducing unnecessary stimuli to “give your brain a rest” may have big impact over decades of your life. The latter may be a more important consideration if you have the APOE4 gene.</p> <p>That’s because the APOE gene is also linked to how the brain uses energy, which may lead to more <a href="https://www.frontiersin.org/articles/10.3389/fnmol.2018.00216/full" target="_blank" rel="noopener">oxidative stress and damage</a>.</p> <p>While we’ve yet to collect robust data in humans, take a digital detox now and again, plan some down time, and avoid unnecessary stress if you can.</p> <p><strong>Should we test for the APOE4 gene?</strong></p> <p>Some people might be tempted to get tested for the APOE4 gene, especially if there’s a family history of Alzheimer’s.</p> <p>But unless genetic testing is going to change your treatment (for instance, by taking certain medications to slow progression of brain damage), or your behaviour to minimise your risk Alzheimer’s, then testing is not justified.</p> <p>We can’t change the genes our parents gifted us, but we can change our environment.</p> <p>Poor diet, every drop of alcohol you drink, obesity and diabetes, high blood pressure and sedentary behaviour <a href="https://www.dementia.org.au/risk-reduction" target="_blank" rel="noopener">all contribute, over time</a>, to poorer vascular health and increase your risk of dementia.</p> <p>We’re still learning about how these risk factors for Alzheimer’s interact with the APOE4 gene. But there is no reason we shouldn’t all take greater responsibility for minimising our risk of dementia now, whether we have the APOE4 gene or not.<!-- Below is The Conversation's page counter tag.
