Simon Dorante-Day calls for "four-way paternity test" to prove royal lineage

Simon Dorante-Day has called for a "four-way paternity test" to prove his royal lineage, while also casting doubt on if Prince William and Prince Harry are actually sons of the monarch. The Queensland man, who has been claiming to be the secret son of King Charles and Queen Camilla since 2005, has called for an official DNA test to prove his claims in a lengthy Facebook post. Dorante-Day's post highlights a photo comparison of himself, King Charles and William and Harry as evidence supporting his demand for answers from the royal family. “This comparison of William, Myself, Charles, and Harry demonstrates something very clearly, there is no consistency. The fact that the left side of my face identically matches Charles whilst neither William nor Harry’s does, raises the obvious question, just who are Charles’s real sons?” "This is why my wife, Dr. Elvianna, and I believe a 4-way Paternity test is the only way to resolve this issue once and for all. The truth of the game that has been played by the Monarchy, the Government, and the Establishment for 58 years needs to be exposed." "It's not just what happened to me as a child, and what I remember from growing up in England, but it’s also what’s happened since to myself, my wife, and my children in Australia that supports our argument. These covert and illegitimate activities that are targeted towards us constantly are an attempt to stop us on this journey, nothing more. They will not succeed. They will only strengthen our argument and provides us with evidence to demonstrate what has occurred, in a court room, to judges." "My question to all of you is how will you truly react when you hear the truth of what has occurred? Would you still want them on the throne?" Dorante-Day was born in Portsmouth in the UK in 1966, and was adopted at just eight months old. According to his claims, his adoptive mother, who worked for Queen Elizabeth II confessed on her death bed that he was the son of Charles and Camilla. Image credits: Facebook

Lisa Curry recounts her Olympics "gender test" ordeal

On Friday, the opening ceremony of the Paris Olympics will begin and swimming legend Lisa Curry has opened up about her own experiences competing in the games, and how she had to take a "gender test" in 1992. "Found this yesterday and thought it would be fun to do a show and tell of a few past stories leading up to Fridays Opening Ceremony of the 2024 Olympic Games in Paris," she shared on Instagram alongside a photo of the gender certificate she received. "This was a card given to all athletes competing in 1992 Barcelona after they completed a 'gender test'," she continued. "I wonder if they still do it?" Curry, 61, was one of the golden girls of Australian swimming, representing the nation at three Olympics during a career that spanned 23 years. The Olympian went on to explain that the man who signed her card was Alexandre de Merode, the head of the drug testing policy for the International Olympic Committee at the time. De Merode had a controversial career after he was involved in a number of Olympic drug scandals at Los Angeles in 1984 and Seoul in 1988. "This definitely surprised me… or does it?" Curry continued. "And it was at these Barcelona Games where we swam against the Chinese swimmers," she added. <blockquote class="instagram-media" style="background: #FFF; border: 0; border-radius: 3px; box-shadow: 0 0 1px 0 rgba(0,0,0,0.5),0 1px 10px 0 rgba(0,0,0,0.15); margin: 1px; max-width: 540px; min-width: 326px; padding: 0; width: calc(100% - 2px);" data-instgrm-permalink="https://www.instagram.com/p/C9vefXRTlW8/?utm_source=ig_embed&utm_campaign=loading" data-instgrm-version="14"> <div style="padding: 16px;"> <div style="display: flex; flex-direction: row; align-items: center;"> <div style="background-color: #f4f4f4; border-radius: 50%; flex-grow: 0; height: 40px; margin-right: 14px; width: 40px;"> </div> <div style="display: flex; flex-direction: column; flex-grow: 1; justify-content: center;"> <div style="background-color: #f4f4f4; border-radius: 4px; flex-grow: 0; height: 14px; margin-bottom: 6px; width: 100px;"> </div> <div style="background-color: #f4f4f4; border-radius: 4px; flex-grow: 0; height: 14px; width: 60px;"> </div> </div> </div> <div style="padding: 19% 0;"> </div> <div style="display: block; height: 50px; margin: 0 auto 12px; width: 50px;"> </div> <div style="padding-top: 8px;"> <div style="color: #3897f0; font-family: Arial,sans-serif; font-size: 14px; font-style: normal; font-weight: 550; line-height: 18px;">View this post on Instagram</div> </div> <div style="padding: 12.5% 0;"> </div> <div style="display: flex; flex-direction: row; margin-bottom: 14px; align-items: center;"> <div> <div style="background-color: #f4f4f4; border-radius: 50%; height: 12.5px; width: 12.5px; transform: translateX(0px) translateY(7px);"> </div> <div style="background-color: #f4f4f4; height: 12.5px; transform: rotate(-45deg) translateX(3px) translateY(1px); width: 12.5px; flex-grow: 0; margin-right: 14px; margin-left: 2px;"> </div> <div style="background-color: #f4f4f4; border-radius: 50%; height: 12.5px; width: 12.5px; transform: translateX(9px) translateY(-18px);"> </div> </div> <div style="margin-left: 8px;"> <div style="background-color: #f4f4f4; border-radius: 50%; flex-grow: 0; height: 20px; width: 20px;"> </div> <div style="width: 0; height: 0; border-top: 2px solid transparent; border-left: 6px solid #f4f4f4; border-bottom: 2px solid transparent; transform: translateX(16px) translateY(-4px) rotate(30deg);"> </div> </div> <div style="margin-left: auto;"> <div style="width: 0px; border-top: 8px solid #F4F4F4; border-right: 8px solid transparent; transform: translateY(16px);"> </div> <div style="background-color: #f4f4f4; flex-grow: 0; height: 12px; width: 16px; transform: translateY(-4px);"> </div> <div style="width: 0; height: 0; border-top: 8px solid #F4F4F4; border-left: 8px solid transparent; transform: translateY(-4px) translateX(8px);"> </div> </div> </div> <div style="display: flex; flex-direction: column; flex-grow: 1; justify-content: center; margin-bottom: 24px;"> <div style="background-color: #f4f4f4; border-radius: 4px; flex-grow: 0; height: 14px; margin-bottom: 6px; width: 224px;"> </div> <div style="background-color: #f4f4f4; border-radius: 4px; flex-grow: 0; height: 14px; width: 144px;"> </div> </div> <p style="color: #c9c8cd; font-family: Arial,sans-serif; font-size: 14px; line-height: 17px; margin-bottom: 0; margin-top: 8px; overflow: hidden; padding: 8px 0 7px; text-align: center; text-overflow: ellipsis; white-space: nowrap;"><a style="color: #c9c8cd; font-family: Arial,sans-serif; font-size: 14px; font-style: normal; font-weight: normal; line-height: 17px; text-decoration: none;" href="https://www.instagram.com/p/C9vefXRTlW8/?utm_source=ig_embed&utm_campaign=loading" target="_blank" rel="noopener">A post shared by Lisa Curry AO (@lisacurry)</a> </div> </blockquote> In the early 1990s, the Chinese swimmers began to dominate the pool and eventually won a lot of medals, however they were also notorious for doping with more than 40 Chinese swimmers failing drug tests during the decade.

Woman found in wheelie bin identified as English teacher

The body of a woman found in a wheelie bin at a waste management facility has been identified as a 67-year-old teacher. Staff at Repurpose It in the north Melbourne suburb of Epping found the body of Annette Brennan while moving green waste last Wednesday. Police believe that the 67-year-old was inside a bin picked up outside a home in Coolaroo on Tuesday July 2nd, which was then taken to the facility in Epping. Brennan spent most of her life teaching English to students, many of whom were international, and has been described as “gentle and kind”. Police have arrested a 45-year-old man in connection to Brennan's death, who has since been charged with murder and will appear in Melbourne Magistrates’ Court on Wednesday. Homicide detectives believe the pair were known to each other. On Monday night, Repurpose It CEO George Hatzimanolis said staff were “deeply saddened” by the incident. “Our staff members who made this tragic discovery are understandably shaken, and we are ensuring they receive the support and counselling they need,” he said. “We ask for privacy and understanding for our employees as we navigate through this challenging situation. We are fully co-operating with the police as they conduct their investigations.” Police are still combing through CCTV in the Coolaroo area and have urged anyone who may have video from between June 23rd and July 2nd to contact them. Detectives are also keen to speak to anyone who noticed any suspicious behaviour in the area. Image credits: Sunrise

Advocates slam "ageist" call for older drivers to undergo mandatory testing

A fresh push to make older drivers undergo mandatory health checks every year has been labelled ageist by advocates. General Practitioners have reignited the debate to introduce annual assessments for drivers in Victoria aged 75 and over, to bring the state in line with standards in other states including NSW, Queensland, WA and the Australian Capital Territory. “This is not about discriminating against older people, but a recognition that the skills that are required to drive safely can be lost as we get older,” the Royal Australian College of General Practitioners Victoria chair Dr Anita Muñoz told The Age. "We do feel that having an annual assessment done for elderly drivers is a good thing," the college's Victoria co-deputy chair Dr Bindiya Sethi added. Victoria Police data obtained by The Age also showed that 145 people have died and 7080 have been injured in road incidents caused by people aged over 65. 20 per cent of licence holders in Victoria are over 65, which has gone up from 16 per cent a decade ago. In the last financial year, there were 247 deaths and 16,265 injuries caused by crashes on Victorian roads, with drivers aged 65 and over responsible for around 10 per cent of these incidences. However, Chris Potaris, chief executive of the Council on the Ageing Victoria and Seniors Rights Victoria, has called the move "ageist". “We continue to support Victoria’s approach, which emphasises a driver’s behaviour and medical fitness to operate a motor vehicle,” he told the publication. “Driving should be based on ability, not on age.” Seniors Rights Victoria policy and advocacy manager Ben Rogers has also slammed the move. "We find it ageist and arbitrary ... It's targeting people that don't need to be targeted," Rogers said. MP Steve Dimopolous added that there was no evidence that an aged-based assessment model was any better than the existing rules. VicRoads also claimed that there is a lot of misinformation about older drivers, who are "usually more cautious, more experienced and more responsible" than younger drivers. "They are more likely to obey the law and are less likely to drink drive or speed," VicRoads said. However, a few others believe that mandatory assessments are a good move. "I think it's fair enough. Over a certain age, maybe 70 or so," local man Pat said. "I think the younger drivers are worse than the older drivers," another added. Image: Getty

Centenarian blood tests give hints of the secrets to longevity

<a href="https://theconversation.com/profiles/karin-modig-1473484">Karin Modig</a>, <a href="https://theconversation.com/institutions/karolinska-institutet-1250">Karolinska Institutet</a> Centenarians, once considered rare, have become commonplace. Indeed, they are the <a href="https://www.weforum.org/agenda/2021/02/living-to-one-hundred-life-expectancy/">fastest-growing demographic group</a> of the world’s population, with numbers roughly doubling every ten years since the 1970s. How long humans can live, and what determines a long and healthy life, have been of interest for as long as we know. Plato and Aristotle discussed and <a href="https://pubmed.ncbi.nlm.nih.gov/12092789/">wrote about the ageing process</a> over 2,300 years ago. The pursuit of understanding the secrets behind exceptional longevity isn’t easy, however. It involves <a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC7105197/">unravelling the complex interplay</a> of genetic predisposition and lifestyle factors and how they interact throughout a person’s life. Now our recent study, <a href="https://link.springer.com/article/10.1007/s11357-023-00936-w">published in GeroScience</a>, has unveiled some common biomarkers, including levels of cholesterol and glucose, in people who live past 90. Nonagenarians and centenarians have long been of intense interest to scientists as they may help us understand how to live longer, and perhaps also how to age in better health. So far, studies of centenarians have often been small scale and focused on a selected group, for example, excluding centenarians who live in care homes. <h2>Huge dataset</h2> Ours is the largest study comparing biomarker profiles measured throughout life among exceptionally long-lived people and their shorter-lived peers to date. We compared the biomarker profiles of people who went on to live past the age of 100, and their shorter-lived peers, and investigated the link between the profiles and the chance of becoming a centenarian. Our research included data from 44,000 Swedes who underwent health assessments at ages 64-99 - they were a sample of <a href="https://pubmed.ncbi.nlm.nih.gov/28158674/">the so-called Amoris cohort</a>. These participants were then followed through Swedish register data for up to 35 years. Of these people, 1,224, or 2.7%, lived to be 100 years old. The vast majority (85%) of the centenarians were female. Twelve blood-based biomarkers related to inflammation, metabolism, liver and kidney function, as well as potential malnutrition and anaemia, were included. All of these <a href="https://www.nature.com/articles/s41591-019-0719-5">have been associated</a> with ageing or mortality in previous studies. The biomarker related to inflammation was uric acid – a waste product in the body caused by the digestion of certain foods. We also looked at markers linked to metabolic status and function including total cholesterol and glucose, and ones related to liver function, such as alanine aminotransferase (Alat), aspartate aminotransferase (Asat), albumin, gamma-glutamyl transferase (GGT), alkaline phosphatase (Alp) and lactate dehydrogenase (LD). We also looked at creatinine, which is linked to kidney function, and iron and total iron-binding capacity (TIBC), which is linked to anaemia. Finally, we also investigated albumin, a biomarker associated with nutrition. <h2>Findings</h2> We found that, on the whole, those who made it to their hundredth birthday tended to have lower levels of glucose, creatinine and uric acid from their sixties onwards. Although the median values didn’t differ significantly between centenarians and non-centenarians for most biomarkers, centenarians seldom displayed extremely high or low values. For example, very few of the centenarians had a glucose level above 6.5 earlier in life, or a creatinine level above 125. For many of the biomarkers, both centenarians and non-centenarians had values outside of the range considered normal in clinical guidelines. This is probably because these guidelines are set based on a younger and healthier population. When exploring which biomarkers were linked to the likelihood of reaching 100, we found that all but two (alat and albumin) of the 12 biomarkers showed a connection to the likelihood of turning 100. This was even after accounting for age, sex and disease burden. The people in the lowest out of five groups for levels of total cholesterol and iron had a lower chance of reaching 100 years as compared to those with higher levels. Meanwhile, people with higher levels of glucose, creatinine, uric acid and markers for liver function also decreased the chance of becoming a centenarian. In absolute terms, the differences were rather small for some of the biomarkers, while for others the differences were somewhat more substantial. For uric acid, for instance, the absolute difference was 2.5 percentage points. This means that people in the group with the lowest uric acid had a 4% chance of turning 100 while in the group with the highest uric acid levels only 1.5% made it to age 100. Even if the differences we discovered were overall rather small, they suggest a potential link between metabolic health, nutrition and exceptional longevity. The study, however, does not allow any conclusions about which lifestyle factors or genes are responsible for the biomarker values. However, it is reasonable to think that factors such as nutrition and alcohol intake play a role. Keeping track of your kidney and liver values, as well as glucose and uric acid as you get older, is probably not a bad idea. That said, chance probably plays a role at some point in reaching an exceptional age. But the fact that differences in biomarkers could be observed a long time before death suggests that genes and lifestyle may also play a role.<img style="border: none !important; box-shadow: none !important; margin: 0 !important; max-height: 1px !important; max-width: 1px !important; min-height: 1px !important; min-width: 1px !important; opacity: 0 !important; outline: none !important; padding: 0 !important;" src="https://counter.theconversation.com/content/215166/count.gif?distributor=republish-lightbox-basic" alt="The Conversation" width="1" height="1" /> <a href="https://theconversation.com/profiles/karin-modig-1473484">Karin Modig</a>, Associate Professor, Epidemiology, <a href="https://theconversation.com/institutions/karolinska-institutet-1250">Karolinska Institutet</a> Image credits: Shutterstock This article is republished from <a href="https://theconversation.com">The Conversation</a> under a Creative Commons license.

Should we still be using RATs to test for COVID? 4 key questions answered

<a href="https://theconversation.com/profiles/hassan-vally-202904">Hassan Vally</a>, <a href="https://theconversation.com/institutions/deakin-university-757">Deakin University</a> We’re currently navigating <a href="https://www.thenewdaily.com.au/life/health/2023/11/15/covid-australia-eighth-wave">an eighth wave</a> of <a href="https://theconversation.com/were-in-a-new-covid-wave-what-can-we-expect-this-time-216820">COVID infections</a> in Australia. However the threat COVID poses to us is significantly less than it has ever been, thanks to immunity we’ve acquired through <a href="https://www.thelancet.com/journals/laninf/article/PIIS1473-3099(22)00801-5/fulltext">a combination</a> of prior infection and vaccination. That said, COVID is by no means behind us. The threat of severe illness remains higher for many people, and we’re all potentially at risk of developing <a href="https://www.health.gov.au/topics/covid-19/long-covid">long COVID</a>. While many people appear to be doing fewer rapid antigen tests (RATs) than they used to – if any at all – with rising cases, and as we head towards the festive season, testing continues to be important. So what do you need to know about testing in this wave? Here are four key questions answered. <h2>1. When should I do a RAT?</h2> There are a few situations where determining your COVID status is important to inform your actions, particularly during an uptick in infections. With more circulating virus, your index of suspicion that you have COVID if you’re experiencing cold-like symptoms should be higher. RATs work best when they’re used to confirm whether you have COVID when you <a href="https://www.tga.gov.au/products/covid-19/covid-19-tests/how-testing-works-covid-19">have respiratory symptoms</a> and are infectious. So the primary use of RATs should be to determine your COVID status when you’re sick. A positive test should prompt you to isolate, and if you’re eligible, to seek antivirals. Testing might also be worthwhile if you’ve come into contact with someone with COVID but you haven’t developed symptoms. If you find you have in fact contracted the virus, you can take steps to avoid spreading it to other people (you can infect others even <a href="https://www.healthline.com/health/what-is-asymptomatic-covid#prevalence">when you’re asymptomatic</a>). This is especially important if you’re going to be socialising in large groups or in contact with people who are vulnerable. Another situation in which to consider testing, particularly at this time of year, is before attending large social gatherings. While the reliability of a RAT is never perfect, do the test as close to the event as possible, because your disease status <a href="https://www.businessinsider.com/omicron-rapid-test-hour-before-party-not-day-before-expert-2021-12">can change quickly</a>. <h2>2. Should I test multiple times?</h2> Yes. RATs are not as sensitive as PCR tests, which is the trade-off we make for being able to do this test at home and <a href="https://www.wsj.com/articles/public-health-officials-pursue-covid-19-tests-that-trade-precision-for-speed-11599562800">getting a rapid result</a>. This means that while if you test positive with a RAT you can be very confident you have COVID, if you test negative, you cannot be as confident that you don’t have COVID. That is, the test may give you a false negative result. Although RATs from different manufacturers have different accuracies, all RATs approved by Australia’s Therapeutic Goods Administration must have a sensitivity of <a href="https://www.tga.gov.au/products/covid-19/covid-19-tests/covid-19-rapid-antigen-self-tests-home-use/covid-19-rapid-antigen-self-tests-are-approved-australia#:%7E:text=For%20rapid%20antigen%20tests%2C%20this,specificity%20of%20at%20least%2098%25.">at least 80%</a>. The way to increase your confidence in a negative result is to do multiple RATs serially – each negative test increases the confidence you can have that you don’t have COVID. If you have symptoms and have tested negative after your first RAT, <a href="https://www.fda.gov/medical-devices/safety-communications/home-covid-19-antigen-tests-take-steps-reduce-your-risk-false-negative-results-fda-safety">the advice</a> is to repeat the test after 48 hours, and potentially a third time after another 48 hours if the second test is also negative. <h2>3. Do RATs detect the latest variants?</h2> Since RATs <a href="https://www.healthdirect.gov.au/covid-19/testing#:%7E:text=Rapid%20antigen%20tests%2C%20or%20RATs,of%20proteins%20of%20the%20virus.">detect particular surface proteins</a> on SARS-CoV-2 (the virus that causes COVID), it’s theoretically possible that as the virus evolves, the reliability of these tests may be affected. However, RATs were designed to detect a part of the virus that is not as likely to mutate, so the hope is these tests <a href="https://www.health.com/do-covid-tests-work-new-variants-7967102">will continue to hold up</a> as SARS-CoV-2 evolves. The performance of RATs is continually being assessed by manufacturers. So far, there’s been no change reported in the ability of these tests to <a href="https://www.ama.com.au/articles/tga-updated-advice-rats-nearing-expiry-and-rats-efficacy-current-strains#:%7E:text=The%20TGA%20has%20received%20evidence,19%20RAT%20post%2Dmarket%20review.">detect the latest variants</a>. <h2>4. Can I rely on expired RATs?</h2> At this point in the pandemic, you might have a few expired tests at the back of your cupboard. Technically the most appropriate advice is to say you should never use a diagnostic test <a href="https://www.tga.gov.au/products/covid-19/covid-19-tests/covid-19-rapid-antigen-self-tests-home-use/covid-19-rapid-antigen-self-tests-are-approved-australia">past its expiry date</a>. As a general principle the performance of a test cannot be guaranteed beyond this date. The risk is that over time the components of the RAT degrade and if you use a test that’s not working optimally, it’s more likely to indicate <a href="https://www.health.com/can-you-use-expired-covid-test-6827970">you don’t have COVID</a> when you actually do, which may have consequences. However, as for all things COVID, the answer is not so black and white. Since these tests were new when they were introduced earlier in the pandemic, manufacturers didn’t have specific data on their performance over time, and so the expiry dates given were necessarily conservative. It’s likely these tests will work beyond the expiry dates on the packet, but just how long and how well they work is a bit of an unknown, so we need to be cautious. The other thing to consider is ensuring you store RATs correctly. Storage instructions should be found on the packet, but the key issue is making sure they’re not exposed to extreme temperatures. In particular, <a href="https://7news.com.au/lifestyle/health-wellbeing/how-to-properly-store-your-at-home-covid-19-rapid-antigen-tests-c-5465412">high temperatures</a> may damage the chemicals in the test which may reduce its sensitivity. <h2>The path from here</h2> Regular upticks in COVID cases are something we’re going to have to get used to. At these times, we should all be a bit more cautious about looking after ourselves and others as we go about our lives. What this looks like will vary for different people depending on their personal circumstances. However, being up to date with <a href="https://theconversation.com/what-are-the-new-covid-booster-vaccines-can-i-get-one-do-they-work-are-they-safe-217804">booster vaccinations</a>, having a plan for <a href="https://www.health.gov.au/topics/covid-19/oral-treatments">accessing antivirals</a> if you’re eligible, <a href="https://theconversation.com/with-covid-surging-should-i-wear-a-mask-217902">wearing masks</a> in high-risk settings and testing all continue to play an important role in responding to COVID.<img style="border: none !important; box-shadow: none !important; margin: 0 !important; max-height: 1px !important; max-width: 1px !important; min-height: 1px !important; min-width: 1px !important; opacity: 0 !important; outline: none !important; padding: 0 !important;" src="https://counter.theconversation.com/content/218016/count.gif?distributor=republish-lightbox-basic" alt="The Conversation" width="1" height="1" /> <a href="https://theconversation.com/profiles/hassan-vally-202904">Hassan Vally</a>, Associate Professor, Epidemiology, <a href="https://theconversation.com/institutions/deakin-university-757">Deakin University</a> Image credits: Getty Images This article is republished from <a href="https://theconversation.com">The Conversation</a> under a Creative Commons license.

Worried about getting a blood test? 5 tips to make them easier (and still accurate)

<a href="https://theconversation.com/profiles/sapha-shibeeb-1481231">Sapha Shibeeb</a>, <a href="https://theconversation.com/institutions/rmit-university-1063">RMIT University</a> Blood tests are a common medical procedure, offering valuable insights into a person’s health. Whether you’re getting a routine check-up, diagnosing a medical condition or monitoring treatment progress, understanding the process can make the experience more comfortable and effective. For the majority of patients, blood collections are a minor inconvenience. Others may feel <a href="https://www.sciencedirect.com/science/article/abs/pii/S0887618506000041">uneasy and anxious</a>. Preparation strategies can help get you through the procedure. <h2>How blood is collected</h2> During venipuncture (blood draw), the phlebotomist (blood collector) inserts a needle through the skin into a vein and a small amount of blood is collected and transferred into a test tube. Tubes are sent to a laboratory, where the blood is analysed. A laboratory technician may count or examine cells and measure the levels of minerals/salts, enzymes, proteins or other substances in the sample. For some tests, blood plasma is separated out by spinning (centrifuging) the sample. Others pass a light beam through the sample to determine the amount of a chemical present. For collection, the phlebotomist usually selects a vein in the crook of your elbow, where veins are readily accessible. Blood can also be drawn from veins in the wrists, fingers or heels. A tourniquet may be applied to restrict blood flow and make the chosen vein puff out. <h2>Different tests require different preparation</h2> Before a blood test, the GP or health-care provider will give you specific instructions. These may include fasting for up to 12 hours or temporarily discontinuing certain medications. It is crucial to follow these guidelines meticulously as they can significantly impact the accuracy of your test results. For example, fasting is required before glucose (blood sugar) and lipids (blood fats) testing because blood sugar and cholesterol levels typically increase after a meal. If the blood test requires fasting, you will be asked not to eat or drink (no tea, coffee, juice or alcohol) for about eight to 12 hours. Water is allowed but smoking should be avoided because it can increase <a href="https://diabetesjournals.org/care/article/19/2/112/19825/Acute-Effect-of-Cigarette-Smoking-on-Glucose">blood sugar, cholesterol and triglyceride levels</a>. Generally, you will be asked to fast overnight and have the blood collection done in the morning. Fasting for longer than 15 hours could impact your results, too, by causing dehydration or the release of certain chemicals in the blood. If you have diabetes, you must consult your doctor prior to fasting because it can increase the risk of hypoglycemia (low blood sugar) in people with type 1 diabetes. Most type 2 diabetics can safely fast before a blood test but there are some exceptions, such as people who are taking certain medications including insulin. <h2>5 tips for a better blood test</h2> To improve your blood collection experience, consider these tips: 1. Hydrate Drink plenty of water right up to 30 minutes before your appointment. Adequate hydration improves blood flow, making your veins more accessible. Avoid <a href="https://academic.oup.com/labmed/article/34/10/736/2657269">strenuous exercise</a> before your blood test, which can increase some blood parameters (such as liver function) while decreasing others (such as sodium). 2. Loose clothing Wear clothing that allows easy access to your arms to ensure a less stressful procedure. 3. Manage anxiety If the sight of blood or the procedure makes you anxious, look away while the needle is inserted and try to keep breathing normally. Distraction can help – virtual reality has been <a href="https://pubmed.ncbi.nlm.nih.gov/31889358/">trialled</a> to reduce needle anxiety in children. You could try bringing something to read or music to listen to. 4. Know your risk of fainting If you’re prone to fainting, make sure to inform the phlebotomist when you arrive. You can have your blood drawn while lying down to minimise the risk of passing out and injury. Hydration helps maintain blood pressure and can also <a href="https://www.ahajournals.org/doi/10.1161/01.CIR.0000101966.24899.CB">reduce the risk</a> of fainting. 5. Discuss difficult veins Some people have smaller or scarred veins, often due to repeated punctures, <a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC4989034/">chemotherapy</a> or blood thinner use. In such cases, venipuncture may require multiple attempts. It is important to talk to the phlebotomist if you feel discomfort or significant pain. A finger prick can be performed as an alternative for some tests, such as blood glucose levels. But other comprehensive tests require larger blood volume. <h2>Blood draws after lymph node removal</h2> Historically, there were concerns about drawing blood from an arm that had undergone lymph node removal. This was due to the risk of <a href="https://www.cancer.gov/about-cancer/treatment/side-effects/lymphedema/lymphedema-pdq#:%7E:text=Lymphedema%20is%20the%20build%2Dup,the%20way%20that%20it%20should.">lymphedema</a>, a condition marked by fluid build-up in the affected arm. Lymph nodes may have been removed (<a href="https://www.ncbi.nlm.nih.gov/books/NBK564397/#:%7E:text=Lymph%20node%20dissection%2C%20also%20known,surgical%20management%20of%20malignant%20tumors.">lymphadenectomy</a>) for cancer diagnosis or treatment. However, a <a href="https://ascopubs.org/doi/10.1200/JCO.2015.61.5948">2016 study</a> showed people who’ve had lymph nodes removed are not at a higher risk of developing lymphedema following blood draws, even when drawing blood from the affected arm. <h2>After your blood test</h2> The whole blood test procedure usually lasts no more than a few minutes. Afterwards, you may be asked to apply gentle pressure over a clean dressing to aid clotting and reduce swelling. If you do experience swelling, bruising or pain after a test, follow general first aid procedures to alleviate discomfort. These include applying ice to the site, resting the affected arm and, if needed, taking a pain killer. It is usually recommended you do not do heavy lifting for a few hours after a blood draw. This is to prevent surges in blood flow that could prevent clotting where the blood was taken.<img style="border: none !important; box-shadow: none !important; margin: 0 !important; max-height: 1px !important; max-width: 1px !important; min-height: 1px !important; min-width: 1px !important; opacity: 0 !important; outline: none !important; padding: 0 !important;" src="https://counter.theconversation.com/content/216073/count.gif?distributor=republish-lightbox-basic" alt="The Conversation" width="1" height="1" /> <a href="https://theconversation.com/profiles/sapha-shibeeb-1481231">Sapha Shibeeb</a>, Senior lecturer in Laboratory Medicine , <a href="https://theconversation.com/institutions/rmit-university-1063">RMIT University</a> Image credits: Shutterstock This article is republished from <a href="https://theconversation.com">The Conversation</a> under a Creative Commons license.

"Ice in his veins": Stunning result in First Ashes Test

Australia has emerged victorious in the first Ashes Test, with captain Pat Cummins chasing down 281 with just two wickets left inside the final five overs on the last day at Edgbaston. Cummins scored an unbeaten 44 as he and Nathan Lyon (16) put on 55 for the ninth wicket to bag the win — a thrilling reversal of Australia’s famous two-run loss at the same ground in 2005. The captain and Lyon hit occasional boundaries, wearing several short balls on the body before Cummins got a thick edge to third man off Robinson and Harry Brook’s fumble on the boundary saw Aussie fans and players erupt in raptures — reigning in a 1-0 lead in the series. "Ice in his veins," England great Michael Atherton said in commentary when Cummins' boundary sealed the result. "Pat Cummins has led his side to a famous victory here at Edgbaston. "Seventy-two they needed when he came to the crease and he has got his team over the line.” Aussie cricket legend Ricky Ponting was astounded. "What an end to a Test match, what a game of cricket," the former captain said. Needing 174 runs to win at the start of the day, in-form opener Usman Khawaja laid a platform for the late charge with 65 off 197 balls, before being bowled late in the day. He admitted he was “Sh****ng [himself]” as he watched the rest of the brutal run chase from the sheds. Despite being confined to a knee brace, Ben Strokes brought himself on to bowl and claimed the wicket of the eventual man of the match, Usman Khawaja. As the Aussie dressing room spiralled into a frenzy, an elated Cummins raced over to Lyon at the opposite end of the wicket and lifted his batting partner off the ground. The pair were then seen in a triumphant embrace as ecstatic Aussies in the Birmingham crowd celebrated the incredible result. The victory — initially appearing highly unlikely when Lyon joined Cummins with the visitors needing 54 runs to win — made for Australia’s highest successful run chase against England since 1948.

A brief history of the mortgage, from its roots in ancient Rome to the English ‘dead pledge’ and its rebirth in America

The average interest rate for a new U.S. <a href="https://www.cbsnews.com/news/home-loan-mortgage-interest-rate-7-percent-highest-since-2001/">30-year fixed-rate mortgage topped 7% in late October 2022</a> for the first time in more than two decades. It’s a sharp increase from one year earlier, when <a href="https://www.valuepenguin.com/mortgages/historical-mortgage-rates">lenders were charging homebuyers only 3.09%</a> for the same kind of loan. Several factors, including <a href="https://www.nerdwallet.com/article/mortgages/fed-mortgage-rates">inflation rates and the general economic outlook</a>, influence mortgage rates. A primary driver of the ongoing upward spiral is the <a href="https://abc7chicago.com/fed-interest-rate-decision-today-hike-federal-reserve-meeting-november/12408055/">Federal Reserve’s series of interest rate hikes</a> intended to tame inflation. Its decision to increase the benchmark rate by <a href="https://www.federalreserve.gov/newsevents/pressreleases/monetary20221102a.htm">0.75 percentage points on Nov. 2, 2022</a>, to as much as 4% will propel the cost of mortgage borrowing even higher. Even if you have had mortgage debt for years, you might be unfamiliar with the history of these loans – a subject I cover <a href="https://scholar.google.com/citations?user=KVv47noAAAAJ&hl=en&oi=ao">in my mortgage financing course</a> for undergraduate business students at Mississippi State University. The term dates back to <a href="https://www.english-heritage.org.uk/learn/story-of-england/medieval/">medieval England</a>. But the roots of these legal contracts, in which land is pledged for a debt and will become the property of the lender if the loan is not repaid, go back thousands of years. <h2>Ancient roots</h2> Historians trace the <a href="https://www.kingjamesbibleonline.org/Nehemiah-5-3/">origins of mortgage contracts</a> to the reign of King Artaxerxes of Persia, who ruled modern-day Iran in the fifth century B.C. The Roman Empire formalized and documented the legal process of pledging collateral for a loan. Often using the <a href="https://www.biblegateway.com/passage/?search=John%202%3A13-16&version=NIV">forum and temples as their base of operations</a>, mensarii, which is derived from the word mensa or “bank” in Latin, would set up loans and charge <a href="https://www.biblegateway.com/passage/?search=John%202%3A13-16&version=NIV">borrowers interest</a>. These government-appointed public bankers required the borrower to put up collateral, whether real estate or personal property, and their agreement regarding the use of the collateral would be handled in one of three ways. First, the <a href="https://www.merriam-webster.com/dictionary/fiducia">Fiducia</a>, Latin for “trust” or “confidence,” required the transfer of both ownership and possession to lenders until the debt was repaid in full. Ironically, this arrangement involved no trust at all. Second, the <a href="https://www.merriam-webster.com/dictionary/pignus">Pignus</a>, Latin for “pawn,” allowed borrowers to retain ownership while <a href="https://scholarship.law.upenn.edu/cgi/viewcontent.cgi?referer=https://www.google.com/&httpsredir=1&article=1684&context=penn_law_review">sacrificing possession and use</a> until they repaid their debts. Finally, the <a href="https://legaldictionary.lawin.org/hypotheca/">Hypotheca</a>, Latin for “pledge,” let borrowers retain both ownership and possession while repaying debts. <h2>The living-versus-dead pledge</h2> <a href="https://www.britannica.com/biography/Claudius-Roman-emperor">Emperor Claudius</a> brought Roman law and customs to Britain in A.D. 43. Over the next <a href="https://www.english-heritage.org.uk/learn/story-of-england/romans/">four centuries of Roman rule</a> and the <a href="https://www.english-heritage.org.uk/learn/story-of-england/early-medieval/">subsequent 600 years known as the Dark Ages</a>, the British adopted another Latin term for a pledge of security or collateral for loans: <a href="https://worldofdictionary.com/dict/latin-english/meaning/vadium">Vadium</a>. If given as collateral for a loan, real estate could be offered as “<a href="https://www.merriam-webster.com/dictionary/vadium%20vivum">Vivum Vadium</a>.” The literal translation of this term is “living pledge.” Land would be temporarily pledged to the lender who used it to generate income to pay off the debt. Once the lender had collected enough income to cover the debt and some interest, the land would revert back to the borrower. With the alternative, the “<a href="https://www.merriam-webster.com/dictionary/mortuum%20vadium">Mortuum Vadium</a>” or “dead pledge,” land was pledged to the lender until the borrower could fully repay the debt. It was, essentially, an interest-only loan with full principal payment from the borrower required at a future date. When the lender demanded repayment, the borrower had to pay off the loan or lose the land. Lenders would keep proceeds from the land, be it income from farming, selling timber or renting the property for housing. In effect, the land was <a href="https://www.jstor.org/stable/pdf/1321129.pdf">dead to the debtor</a> during the term of the loan because it provided no benefit to the borrower. Following <a href="https://www.royal.uk/william-the-conqueror">William the Conqueror’s victory</a> at the Battle of Hastings in 1066, the English language was heavily influenced by <a href="https://blocs.mesvilaweb.cat/subirats/the-norman-conquest-the-influence-of-french-on-the-english-language-loans-and-calques/">Norman French</a> – William’s language. That is how the Latin term “Mortuum Vadium” morphed into “Mort Gage,” Norman French for “dead” and “pledge.” “<a href="https://www.etymonline.com/word/mortgage">Mortgage</a>,” a <a href="https://ia600201.us.archive.org/1/items/cu31924021674399/cu31924021674399.pdf">mashup of the two words</a>, then entered the English vocabulary. <h2>Establishing rights of borrowers</h2> Unlike today’s mortgages, which are usually due within 15 or 30 years, English loans in the 11th-16th centuries were unpredictable. <a href="https://www.jstor.org/stable/pdf/1323192.pdf">Lenders could demand repayment</a> at any time. If borrowers couldn’t comply, lenders could seek a court order, and the land would be forfeited by the borrower to the lender. Unhappy borrowers could <a href="https://www.law.cornell.edu/wex/chancery">petition the king</a> regarding their predicament. He could refer the case to the lord chancellor, who could <a href="https://www.britannica.com/topic/Chancery-Division">rule as he saw fit</a>. <a href="https://www.britannica.com/biography/Francis-Bacon-Viscount-Saint-Alban">Sir Francis Bacon</a>, England’s lord chancellor from 1618 to 1621, <a href="https://www.jstor.org/stable/752041">established</a> the <a href="https://www.law.cornell.edu/wex/equity_of_redemption">Equitable Right of Redemption</a>. This new right allowed borrowers to pay off debts, even after default. The official end of the period to redeem the property was called <a href="https://www.law.cornell.edu/wex/foreclosure">foreclosure</a>, which is derived from an Old French word that means “<a href="https://www.etymonline.com/word/foreclose">to shut out</a>.” Today, foreclosure is a legal process in which lenders to take possession of property used as collateral for a loan. <h2>Early US housing history</h2> The <a href="https://www.loc.gov/classroom-materials/united-states-history-primary-source-timeline/colonial-settlement-1600-1763/overview/">English colonization</a> of what’s now <a href="https://themayflowersociety.org/history/the-mayflower-compact/">the United States</a> didn’t immediately transplant mortgages across the pond. But eventually, U.S. financial institutions were offering mortgages. <a href="https://www.huduser.gov/publications/pdf/us_evolution.pdf">Before 1930, they were small</a> – generally amounting to at most half of a home’s market value. These loans were generally short-term, maturing in under 10 years, with payments due only twice a year. Borrowers either paid nothing toward the principal at all or made a few such payments before maturity. Borrowers would have to refinance loans if they couldn’t pay them off. <h2>Rescuing the housing market</h2> Once America fell into the <a href="https://www.history.com/topics/great-depression">Great Depression</a>, the <a href="https://www.stlouisfed.org/news-releases/2008/05/02/does-the-great-depression-hold-the-answers-for-the-current-mortgage-distress">banking system collapsed</a>. With most homeowners unable to pay off or refinance their mortgages, the <a href="https://www.federalreservehistory.org/essays/great-depression">housing market crumbled</a>. The number of <a href="https://www.encyclopedia.com/education/news-and-education-magazines/housing-1929-1941">foreclosures grew to over 1,000 per day by 1933</a>, and housing prices fell precipitously. The <a href="https://www.fhfaoig.gov/Content/Files/History%20of%20the%20Government%20Sponsored%20Enterprises.pdf">federal government responded by establishing</a> new agencies to stabilize the housing market. They included the <a href="https://www.hud.gov/program_offices/housing/fhahistory">Federal Housing Administration</a>. It provides <a href="https://www.consumerfinance.gov/ask-cfpb/what-is-mortgage-insurance-and-how-does-it-work-en-1953/">mortgage insurance</a> – borrowers pay a small fee to protect lenders in the case of default. Another new agency, the <a href="https://sf.freddiemac.com/articles/insights/why-americas-homebuyers-communities-rely-on-the-30-year-fixed-rate-mortgage">Home Owners’ Loan Corp.</a>, established in 1933, bought defaulted short-term, semiannual, interest-only mortgages and transformed them into new long-term loans lasting 15 years. Payments were monthly and self-amortizing – covering both principal and interest. They were also fixed-rate, remaining steady for the life of the mortgage. Initially they skewed more heavily toward interest and later defrayed more principal. The corporation made new loans for three years, tending to them until it <a href="https://content.time.com/time/subscriber/article/0,33009,858135,00.html">closed in 1951</a>. It pioneered long-term mortgages in the U.S. In 1938 Congress established the Federal National Mortgage Association, better known as <a href="https://www.fanniemae.com/about-us/who-we-are/history">Fannie Mae</a>. This <a href="https://www.financial-dictionary.info/terms/government-sponsored-enterprise/">government-sponsored enterprise</a> made fixed-rate long-term mortgage loans viable <a href="https://www.investopedia.com/terms/s/securitization.asp">through a process called securitization</a> – selling debt to investors and using the proceeds to purchase these long-term mortgage loans from banks. This process reduced risks for banks and encouraged long-term mortgage lending. <h2>Fixed- versus adjustable-rate mortgages</h2> After World War II, Congress authorized the Federal Housing Administration to insure <a href="https://www.govinfo.gov/content/pkg/CPRT-108HPRT92629/html/CPRT-108HPRT92629.htm">30-year loans on new construction</a> and, a few years later, purchases of existing homes. But then, the <a href="https://files.stlouisfed.org/files/htdocs/publications/review/69/09/Historical_Sep1969.pdf">credit crunch of 1966</a> and the years of high inflation that followed made adjustable-rate mortgages more popular. Known as ARMs, these mortgages have stable rates for only a few years. Typically, the initial rate is significantly lower than it would be for 15- or 30-year fixed-rate mortgages. Once that initial period ends, <a href="https://www.investopedia.com/terms/a/arm.asp">interest rates on ARMs</a> get adjusted up or down annually – along with monthly payments to lenders. Unlike the rest of the world, where ARMs prevail, Americans still prefer the <a href="https://sf.freddiemac.com/articles/insights/why-americas-homebuyers-communities-rely-on-the-30-year-fixed-rate-mortgage">30-year fixed-rate mortgage</a>. About <a href="https://data.census.gov/cedsci/table?q=DP04&t=Housing">61% of American homeowners</a> have mortgages today – with <a href="https://doi.org/10.1080/15214842.2020.1757357">fixed rates the dominant type</a>. But as interest rates rise, demand for <a href="https://www.corelogic.com/intelligence/interest-rates-are-up-but-arm-backed-home-purchases-are-way-up/">ARMs is growing</a> again. If the Federal Reserve fails to slow inflation and interest rates continue to climb, unfortunately for some ARM borrowers, the term “dead pledge” may live up to its name.

00-No: US traveller puts border security to the test with a golden gun

A 28-year-old traveller from the United States has been arrested after Australian Border Force officers allegedly discovered a firearm in her luggage. According to a report on the ABF website, the weapon - a 24-carat gold-plated handgun - was unregistered, and the passenger was not in possession of “a permit to import or possess the firearm in Australia.” If convicted, she will face up to 10 years of imprisonment. And while she was arrested and charged, she was released on bail at Downing Centre Local Court, and is expected to face court again in a month’s time. She remains subject to visa cancellation, and faces the likelihood of being removed from Australia. As ABF Enforcement and Detained Goods East Commander Justin Bathurst explained, the discovery was made with a combination of ABC officer skills and detection technology, one that served to prevent a dangerous weapon from entering the Australian community. “Time and time again, we have seen just how good ABF officers are at targeting and stopping illegal, and highly dangerous, goods from crossing Australia's border," he said. “The ABF is Australia's first and most important line of defence. ABF officers are committed to protecting our community by working with law enforcement partners to prevent items like unregistered firearms getting through at the border." Photos distributed by the ABF present the image of the gun in its case, as well as a scan of the passenger’s luggage, with the gun clearly visible among the rest of her possessions. While travellers on domestic flights within the United States are able to carry firearms in their checked luggage - granted they are unloaded and securely locked away, and the proper authorities have been informed - Australia has much stricter laws surrounding firearms. In the wake of a 1996 Tasmanian tragedy, in which 35 people lost their lives to a gunman, all automatic and semi-automatic weapons were outlawed in the country. Meanwhile, in the United States, a frightening sum of 6,301 were confiscated at checkpoints as of December 2022, according to the Transportation Security Administration. For many, the news was broken on social media, with comments sections reflecting the shock - and disapproval - of the masses, with the occasional 007 reference thrown in. “Smuggling firearms into Australia is a serious offence,” wrote one on Twitter, “and should be met with the full force of the law as it endangers citizen safety.” “That’s a fantastic bit of security work by our airport staff,” someone commended. Another had one very important question, asking “how did she get it out of the US to begin with...??? TSA should have caught that at the airport before she even left. Even if it was in a checked bag, it still had to be declared.” Images: Australian Border Force

Travel Trouble

The most misused word in the English language

A traffic jam when you’re already late. A free ride when you’ve already paid. The fact that the King James Bible is the most shoplifted book in the United States. One of these three things is an example of irony – the reversal of what is expected or intended. The other two (no offense to Alanis Morissette) are not. The difference between them may be one of the most rage-inducing linguistic misunderstandings you’re likely to read about on the Internet or hear about from the determined grammar nerds in your life. “Ironic” does not, technically, mean “unfortunate,” “interesting” or “coincidental,” despite these terms often being used interchangeably. And that frequent misuse has not escaped linguists. According to the editors at <a href="http://WWW.DICTIONARY.COM">Dictionary.com</a>, “We submit that ironic might be the most abused word in the English language.” That’s a tough claim to prove, but it’s clear that confusion over the definition of irony is persistent and decades old. “Irony” makes Harvard linguist Steven Pinker’s <a href="https://www.independent.co.uk/life-style/the-58-most-commonly-misused-words-and-phrases-a6754551.html">list</a> of the 58 most commonly misused words in English, and ranks in the top 1 percent of all word lookups on Merriam-Webster’s online dictionary. Even Great Gatsby author F. Scott Fitzgerald got it wrong, some say, when he claimed in 1939, “It is an ironic thought that the last picture job I took yielded me five thousand dollars five hundred and cost over four thousand in medical attention.” So what does irony mean, really, and where does the confusion come from? Part of the ambiguity probably stems from the fact that there are no fewer than three definitions of irony depending on which dictionary you use. There’s Socratic irony (an ancient rhetorical move), and dramatic irony (an ancient theatrical move), but the definition of irony we care about – and the kind that’s most bitterly debated – is situational irony. Situational irony occurs when, as the Oxford English Dictionary defines it, “a state of affairs or an event… seems deliberately contrary to what one expects and is often wryly amusing as a result”. The trick, according to purists, is the deliberately contrary part – for a situation to be ironic, it must be the opposite of what is expected, not merely an amusing coincidence. A traffic jam when you’re already late may be an undesirable coincidence, but it is not the opposite outcome one would expect when leaving for work late (especially if that person lives in a major city). In an article titled <a href="http://www.collegehumor.com/post/229130/lines-from-alanis-morissettes-ironic-modified-to-actually-make-them-ironic">Lines From Alanis Morissette’s “Ironic,” Modified to Actually Make them Ironic</a>, College Humor writer Patrick Cassels corrects the situation like this: “A traffic jam when you’re already late… to receive an award from the Municipal Planning Board for reducing the city’s automobile congestion 80 per cent.” Now that’s irony. Not every linguist goes by this limited view, though. Ever the champions of fluid language growth, Merriam Webster <a href="https://www.merriam-webster.com/dictionary/irony">argues</a> that Mr. Fitzgerald, Ms. Morissette, and anyone else who uses “ironic” to mean “coincidental” isn’t actually wrong, but is actually just trailblazing. “The word irony has come to be applied to events that are merely curious or coincidental,” the editors write, “and while some feel this is an incorrect use of the word, it is merely a new one.” Now isn’t that something.

Madeleine McCann's parents speak out after DNA test results

Madeleine McCann's parents have spoken out after the results of Julia Faustyna's DNA test have returned. Julia Faustyna, a 21-year-old Polish woman, has been claiming to be the missing British child in a high-profile campaign that has seen her undergo a DNA test to prove her identity. The DNA results determined that Julia is not Maddie, despite Julia's claims of having similar facial features, suffering an abusive childhood and had starting to question her parentage as a result. Private detective Dr Fia Johansson arranged for Julia to give samples in the US for extensive DNA tests - including a DNA test similar to a 23andMe test, which established she is not Madeleine. The test looked into her heritage, and showed that she is from Poland, with some Lithuanian and Romanian heritage, <a href="https://www.thesun.co.uk/news/21808585/who-julia-wendell-madeleine-mccann/" target="_blank" rel="noopener">The Sun</a> reported, but nothing to suggest any link to the McCann's. In response, a spokesman for Madeleine’s parents Kate and Gerry McCann said, “There isn’t anything to report at this time. If and when there is, it will come from The Metropolitan Police.” Julia is also facing a nervous wait for the results of further health tests as doctors fear she <a href="https://oversixty.com.au/news/news/sad-health-news-for-woman-claiming-to-be-madeleine-mccann" target="_blank" rel="noopener">may have leukaemia</a>, Dr Johansson - with Julia’s permission - revealed to The Sun. She said, “Her health is very poor she has bad asthma and she suffers lots of pain in her bones." “She is booked in for a CT and MRI scan because of the pain in her bones." “Her blood work is also abnormal so my doctor here in the US is investigating whether she could have leukaemia so we are awaiting the results of that." “And if she needs any treatment we will make sure she gets that.” Image credits: Getty Images

Age, not weight, should be the big decider in whether to screen for diabetes

Because it’s possible to be diabetic or prediabetic without any symptoms, and early diagnoses lead to better health outcomes, lots of countries have screening programs for diabetes. <div class="copy"> In the US, overweight or obese people between 35 and 70 are recommended to regularly get diabetes tests. But <a href="https://www.ajpmonline.org/article/S0749-3797(23)00006-5/fulltext" target="_blank" rel="noreferrer noopener">new research</a> in the American Journal of Preventative Medicine has called this into question, suggesting that screening based purely on age will catch the greatest proportion of diabetic and prediabetic people. “It might sound counterintuitive because we think of being overweight or obese as the primary cause of diabetes,” says lead author Dr Matthew O’Brien, an associate professor of medicine at Northwestern University Feinberg School of Medicine, US. “But if we make decisions about diabetes testing based on weight, we will miss some people from racial and ethnic minority groups who are developing prediabetes and diabetes at lower weights.” The researchers examined data from all the 2021 diabetes screenings recommended by the US Preventive Services Task Force. Based on this data, they recommend screening every US adult aged between 35 and 70. “All major racial and ethnic minority groups develop diabetes at lower weights than white adults, and it’s most pronounced for Asian Americans,” says O’Brien. Roughly half of US adults have Type 2 diabetes or prediabetes, and 81% of adults with prediabetes don’t know they have it. Diagnoses are delayed in ethnic minorities, compared to white people. “Diabetes is a condition in which unacceptable racial and ethnic disparities persist,” says O’Brien. “That’s why we need a screening approach that maximises equity. If we can find everyone earlier, it helps us reduce these disparities and the bad outcomes that follow.” The researchers also found that it might be beneficial for members of some ethnic minorities to receive earlier screening, but they don’t formally recommend it. “It’s imperative that we identify a screening approach that is equitable across the entire US population,” says O’Brien. “Our findings illustrate that screening all adults aged 35 to 70 years, regardless of weight or body mass index, performs equitably across all racial and ethnic groups.” This age cut-off also makes it much simpler for clinicians to decide whether someone should get a diabetes test. “There are many ways to nudge patients and providers to complete this testing, which should be the focus of future research,” says O’Brien. In Australia, diabetes tests are recommended based on a <a href="https://www.healthdirect.gov.au/diabetes-screening-tests" target="_blank" rel="noreferrer noopener">range of risk factors</a>, including age, waist measurement, ethnicity, physical activity and family history. Diabetes Australia has a <a href="https://www.diabetesaustralia.com.au/risk-calculator/" target="_blank" rel="noreferrer noopener">risk calculator</a> with which you can determine your own risk.  <img id="cosmos-post-tracker" style="opacity: 0; height: 1px!important; width: 1px!important; border: 0!important; position: absolute!important; z-index: -1!important;" src="https://syndication.cosmosmagazine.com/?id=240911&title=Age%2C+not+weight%2C+should+be+the+big+decider+in+whether+to+screen+for+diabetes" width="1" height="1" data-spai-target="src" data-spai-orig="" data-spai-exclude="nocdn" /></div> <div id="contributors"> This article was originally published on <a href="https://cosmosmagazine.com/health/diabetes-tests-screening-age-weight/" target="_blank" rel="noopener">cosmosmagazine.com</a> and was written by <a href="https://cosmosmagazine.com/contributor/ellen-phiddian">Ellen Phiddian</a>.

Hilarious footage emerges of Sam Neill's James Bond screen test

Jurassic Park star Sam Neill appeared on the Today show to discuss his career and new memoir 'Did I Ever Tell You This?' but the hosts had other plans. Karl Stefanovic, Sarah Abo and Brooke Boney managed to dig up an old screen test that left the 75-year-old red-faced. "Oh, my God, no - That is so cruel to play that, so cruel," a flustered Neil said, as footage from his James Bond audition started rolling. In the video, a young Neill armed with a gun and donning an unbuttoned shirt bursts into a bedroom-to the surprise of a naked woman- and says the famous line "My friends called me Bond, James Bond". Neill said he was thankful that he didn’t get the part and that someone else was chosen to do the role. "I felt so awkward all day that we made that thing and it just went on and on and on," he said. "I am so relieved they offered it to someone else, they are welcome to it - you don't want to be the Bond that no-one likes, you know - that is a fate worse than death." Although he didn’t get the role of agent 007, the actor has starred in three of the Jurassic Park films, Event Horizon, The Dish and Peter Rabbit. He also told the Today show hosts that he never intended on becoming a professional actor and his success was completely unexpected. "I never really imagined I would have a career in film, let alone a career as an actor," he said. "At the rather advanced age of 30 I suddenly realised I could make a living at what I loved best and I never looked back until I wrote (the memoir) and it has been good to look back - it has been really good for me."

Lie detection tests have worked the same way for 3,000 years – and they’re still hopelessly inaccurate

Popular culture is fascinated with the ability to detect liars. Lie detector tests are a staple of police dramas, and TV shows such as Poker Face feature “human polygraphs” who detect deception by picking up tell-tale signs in people’s behaviour. Records of attempts to detect lies, whether by technical means or by skilled observers, go back at least 3,000 years. Forensic science lie detection techniques have become <a href="https://onlinelibrary.wiley.com/doi/10.1111/j.1541-1338.2005.00166.x">increasingly popular</a> since the invention of the polygraph early in the 20th century, with the latest methods involving advanced brain imaging. Proponents of lie detection technology sometimes <a href="https://www.press.umich.edu/3091709/lying_brain">make grandiose claims</a>, such as a <a href="https://doi.org/10.1007/s11896-022-09566-y">recent paper</a> that said “with the help of forensic science and its new techniques, crimes can be easily solved”. Despite these claims, an infallible lie detection method has yet to be found. In fact, most lie detection methods don’t detect lies at all – instead, they register the physiological or behaviour signs of stress or fear. <h2>From dry rice to red-hot irons</h2> The <a href="https://journals.sagepub.com/doi/10.1177/1529100610390861">earliest recorded lie detection method</a> was used in China, around 1000 BC. It involved suspects placing rice in their mouths then spitting it out: wet rice indicated innocence, while dry rice meant guilty. In India, around 900 BC, <a href="http://scholarlycommons.law.northwestern.edu/cgi/viewcontent.cgi?article=2844&context=jclc">one method</a> used to detect poisoners was observations of shaking. In ancient Greece a rapid pulse rate was taken to indicate deceit. The Middle Ages saw barbaric forms of lie detection used in Europe, such as the red-hot iron method which involved suspected criminals placing their tongue, often multiple times, on a red-hot iron. Here, a burnt tongue indicated guilt. <h2>What the polygraph measures</h2> Historical lie detection methods were based in superstition or religion. However, in the early 20th century a purportedly scientific, objective, lie detection machine was invented: the polygraph. The <a href="https://www.ojp.gov/pdffiles1/nij/grants/228091.pdf">polygraph measures</a> a person’s respiration, heart rate, blood pressure, and skin conductance (sweating) during questioning. Usually a “control question” about a crime is asked, such as “Did you do it?” The person’s response to the control question is then compared to responses to neutral or less provocative questions. Heightened reactions to direct crime questions are taken to indicate guilt on the test. <h2>The overconfidence of law enforcers</h2> Some law enforcement experts claim they don’t even need a polygraph. They can detect lies simply by observing the behaviour of a suspect during questioning. Worldwide research shows that law enforcers are often <a href="https://doi.org/10.5093/apj2022a4">confident they can detect lying</a>. Many assume a suspect’s nonverbal behaviour reveals deceit. A <a href="https://www.emerald.com/insight/content/doi/10.1108/14636641111134314/full/html">2011 study with Queensland police</a> revealed many officers were confident they could detect lying. Most favoured a focus on nonverbal behaviour even over available evidence. However, <a href="https://link.springer.com/chapter/10.1007/978-3-319-96334-1_3">research shows</a> that law enforcers, despite their confidence, are often not very good at detecting lying. Law enforcement officers are not alone in thinking they can spot a liar. <a href="https://journals.sagepub.com/doi/10.1177/0022022105282295">Global studies</a> have found that people around the world believe lying is accompanied by specific nonverbal behaviours such as gaze aversion and nervousness. <h2>What’s really being tested</h2> Many historical and current lie detection methods seem underpinned by the plausible idea that liars will be nervous and display observable physical reactions. These might be shaking (such as in the ancient Indian test for poisoners, and the nonverbal behaviour method used by some investigators), a dry mouth (the rice-chewing test and the hot-iron method), increased pulse rate (the ancient Greek method and the modern polygraph), or overall heightened physiological reactions (the polygraph). However, there are two major problems with using behaviour based on fear or stress to detect lying. The first problem: how does one distinguish fearful innocents from fearful guilty people? It is likely that an innocent person accused of a crime will be fearful or anxious, while a guilty suspect may not be. This is borne out with the polygraph’s <a href="https://nap.nationalacademies.org/read/10420/chapter/10#218">high false-positive rate</a>, meaning innocent people are deemed guilty. Similarly, some police have assumed that <a href="https://cqu-primo.hosted.exlibrisgroup.com/permalink/f/1rb43gr/TN_cdi_informaworld_taylorfrancisbooks_9781843926337">innocent, nervous suspects were guilty</a> based on inaccurate interpretations of behavioural observations. The second major problem with lie detection methods based on nervous behaviour is there is <a href="https://journals.copmadrid.org/apj/art/apj2019a9">no evidence</a> that specific nonverbal behaviours reliably accompany deception. <h2>Miscarriages of justice</h2> Despite what we know about the inaccuracy of polygraph tests, they haven’t gone away. In the US, they are still used in some police interrogations and <a href="https://www.wired.com/story/inside-polygraph-job-screening-black-mirror/">high-security job interviews</a>. In the UK, lie detector tests are used for <a href="https://www.gov.uk/government/publications/domestic-abuse-bill-2020-factsheets/mandatory-polygraph-tests-factsheet">some sex offenders on probation</a>. And in China, the use of polygraphs in law enforcement may <a href="https://www.sciencedirect.com/science/article/abs/pii/S0031938414005964?via%3Dihub">even be increasing</a>. Australia has been less enthusiastic in adopting lie-detection machines. In New South Wales, the use of lie-detector findings was barred from court in 1983, and an attempt to present polygraph evidence to a court in Western Australia in 2003 <a href="https://www.tandfonline.com/doi/abs/10.1375/pplt.2004.11.2.359">also failed</a>. Many historical and current lie detection methods emulate each other and are based on the same assumptions. Often the <a href="https://muse.jhu.edu/book/13865">only difference</a> is the which part of the body or physical reaction they focus on. Using fallible lie detection methods <a href="https://journals.copmadrid.org/apj/art/apj2022a4">contributes to wrongful convictions</a> and miscarriages of justice. Therefore, it is important that criminal-justice practitioners are educated about fallacious lie detection methods, and any new technique grounded in fear or stress-based reactions should be rejected. Despite outward appearances of technological advancement, over many millennia little has changed. Fearful innocents remain vulnerable to wrongful assumptions of guilt, which is good news for the fearless guilty.

Julia Faustyna takes DNA test to prove wild identity claims

Julia Faustyna, the Polish woman who is convinced she is the missing Madeleine McCann, has reportedly taken a DNA test to prove her claim. However, in a stunning twist to the tale, Faustyna’s private investigation with spokesperson Dr Fia Johansson has led the young woman to consider the possibility that she may actually be another missing child - Livia Schepp, who went missing with her twin sister in Switzerland in 2011. “I’ve spoken to her about this and she is open to the fact she could be any missing child out there,” Dr Johansson said while speaking to The Sun. “Not just Madeleine. Julia wants to know the truth about who she is.” While Faustyna’s main argument has involved the physical similarities between herself and Madeleine McCann, one of the pivotal points in her story is how she recognised a suspect from McCann’s case - a man she has named as her own abuser. “One of the reasons she made the connection to Madeleine is because one of the suspects in Madeleine’s case looks very much like a man who she says abused her as a child,” Dr Johansson explained. “But the same man could be connected to Madeleine and other missing children, this is how predators and traffickers work.” “Julia has taken a DNA test,” she confirmed, “and we are investigating if it’s possible to check her DNA with that of [the] missing Livia. We are investigating all possibilities at this stage.” Livia Schepp - and her twin sister Alessia - went missing when they were six, after their father abducted them from Switzerland in 2011. Days later, he took his own life in Italy, and when police discovered the body, the twins were nowhere to be seen. Faustyna, who claims to have post-traumatic amnesia due to sexual abuse in her childhood, lacks clear recollection of her formative years, and has stated while she can recall holidays, she doesn’t “recall my mother being there, for example, or my stepfather, much less my dad.” Whether or not any of Faustyna’s theories are true, the public will have to keep speculating, as no results have yet been shared. However, Faustyna’s viral “@iammadeleinemccan”, where she was sharing updates and side-by-side comparisons with her followers, has since been deleted from the platform. The removal coincides with reports of the DNA test, and after Faustyna closed both her Facebook and Tiktok accounts, disputing her parent’s claim that she was only in this for attention when she said “if you don’t like me, please unfollow. I don’t want fans or followers.” Images: Instagram, Twitter

Is my RAT actually working? How to tell if your COVID test can detect Omicron

You’ve tested negative for COVID using a rapid antigen test (RAT), but are a close contact of a positive family member and have symptoms. So you might be wondering if you’re really COVID-negative or if the test is working as well as it should. There are many reasons why your RAT may not give you <a href="https://theconversation.com/15-things-not-to-do-when-using-a-rapid-antigen-test-from-storing-in-the-freezer-to-sampling-snot-176364">the results</a> <a href="https://theconversation.com/my-rats-are-negative-but-i-still-think-i-might-have-covid-should-i-get-a-pcr-test-194527">you expect</a>. But one factor is whether RATs can detect the Omicron variant of SARS-CoV-2 (the virus that causes COVID). We know the virus has mutated during the pandemic. So health authorities and researchers are investigating whether RATs can still detect the <a href="https://www.who.int/activities/tracking-SARS-CoV-2-variants">more recent versions</a> of the virus. The good news is, based on the <a href="https://www.tga.gov.au/sites/default/files/2022-10/post-market-review-of-antigen-and-rapid-antigen-tests-table.pdf">limited data released</a>, all RATs meant for use at home in Australia that have been independently tested so far seem to be able to detect Omicron. The bad news is that not all RATs have been independently tested yet. Yours might be one of those. <h2>What do mutations have to do with RATs?</h2> RATs diagnose COVID infection by detecting specific viral proteins. So there are concerns that as the virus evolves and produces altered viral proteins, this may affect the tests’ ability to diagnose COVID as well as they detected previous variants. Whether RATs can adequately detect Omicron has been raised by authorities and researchers in various countries including <a href="https://www.bmj.com/content/378/bmj-2022-071215">The Netherlands</a>, <a href="https://pubmed.ncbi.nlm.nih.gov/35458384/">Belgium</a> and <a href="https://pubmed.ncbi.nlm.nih.gov/36339133/">Chile</a>, as well as Australia. One <a href="https://journals.asm.org/doi/10.1128/jcm.01097-22">Australian study</a> tested six RATs on Delta, and Omicron lineages BA.4, BA.5 and BA.2.75. The researchers found the kits performed equally well across the different samples at higher viral loads (higher concentrations of the virus), although one kit’s overall sensitivity fell below minimum sensitivity requirements. However, <a href="https://pubmed.ncbi.nlm.nih.gov/36339133/">some international studies</a> have found RATs are less able to detect Omicron, particularly when <a href="https://pubmed.ncbi.nlm.nih.gov/36339133/">viral loads are lower</a>. <h2>So what’s the case in Australia?</h2> Australia’s regulator, the Therapeutic Goods Administration (TGA), initially relied on <a href="https://www.tga.gov.au/products/covid-19/covid-19-tests/post-market-review-antigen-and-rapid-antigen-tests">test data</a> provided by RAT manufacturers to determine the test kit met World Health Organization <a href="https://www.who.int/publications/m/item/technical-specifications-for-selection-of-essential-in-vitro-diagnostics-for-sars-cov-2">standards</a> for acceptable sensitivity (ability to detect a positive case). The TGA also requires manufacturers to send updated test data as new variants arise to demonstrate their test still meets those WHO standards. But the TGA has also commissioned <a href="https://www.tga.gov.au/products/covid-19/covid-19-tests/post-market-review-antigen-and-rapid-antigen-tests">independent testing of RATs</a> to verify how well they detect the more recent COVID variants. They are tested for their ability to detect the wild-type virus (the original strain), the Delta variant, and the Omicron variant. The TGA does not state which specific lineages (descendents) of Omicron are included in the testing. As it completes its analysis on individual tests (or groups of tests), the TGA reports them in a <a href="https://www.tga.gov.au/sites/default/files/2022-10/post-market-review-of-antigen-and-rapid-antigen-tests-table.pdf">table that’s publicly available</a>, which will be updated as more data come in. <h2>What does the table tell us?</h2> You can look up the brand name, manufacturer and batch number of the RAT you have at home. Look for those labelled “self-tests” (more on the different types of tests and their results later). The most important columns in the table are those that indicate whether the kit passed its independent validation. Look for four ticks to indicate the kit meets minimum standards for detecting the original virus, Delta and Omicron variants, and has passed the quality test. A cross indicates is has not passed that component of the validation. Haven’t found a result for your RAT? If a product comes in two versions – a self-test and a type of test used in health-care facilities known as a point-of-care test (POCT in the table) – only one may be tested. If that’s the case, the symbol † means testing was only done on one version and you can use those results for your test. Look for a matching registration number to make sure you’re comparing like with like. The final column indicates what type of data the manufacturer has provided. Some manufacturers have tested the sensitivity of their kits for Omicron lineages BA.4 and BA.5. <h2>What does the table not tell us?</h2> Just because your test has no ticks or crosses against it, this doesn’t mean it can’t detect Omicron. It could be that the independent validation has yet to be completed or uploaded to the table. So the jury is out. The table also does not tell us what lineages of Omicron were tested for, although in some cases the manufacturer has supplied clinical test data. The table data were only current as of October. Seeing as the number of cases of sub-variant infections <a href="https://theconversation.com/what-can-we-expect-from-this-latest-covid-wave-and-how-long-is-it-likely-to-last-194444">has risen since then</a>, so we don’t really know if that is impacting on the sensitivity of even those tests that have recently been validated. <h2>I’ve grappled with the table, now what?</h2> If your brand of RAT has the ticks, particularly for Omicron, it has been assessed has having an acceptable sensitivity. If you are buying a RAT, check the table to see if that brand has been tested for sensitivity to the Omicron variant. If your test has been sitting in a cupboard for months, check the expiry date before you use it. Also consider whether it has been stored at the correct temperature during that time (the instruction leaflet will tell you what that is).

There’s a serious ethical problem with some sunscreen testing methods – and you’re probably not aware of it

As summer approaches, we need to start remembering to slip on sun-protective clothing, slop on sunscreen, slap on a hat, seek shade where possible, and slide on sunglasses. When it comes to sunscreen, we all know we need to wear it to protect against the harmful effects of ultraviolet (UV) radiation, which can cause skin cancer. But what about the sun protection factor, known as the SPF rating, we see on our sunscreen bottles? It indicates the level of protection – but is it always what it says it is, and how is it actually tested? <h2>Risking human health for SPF testing</h2> While there have been some cases of <a href="https://www.tga.gov.au/news/news/sunscreen-testing-ama-laboratories-condition-listing">sunscreens not matching up to their SPF claims</a>, this is the exception and not the norm. In Australia, we can be comfortable knowing these products are tightly regulated to ensure they are safe and meet their claimed SPF rating, according to current SPF testing methods. However, problems arise when it comes to how sunscreens are tested for their SPF rating. Most people would not be aware that the SPF value on their sunscreen bottles is determined by testing on humans. Ultimately, this means we are risking people’s health to test how effective our sunscreens are – and we urgently need to change this. <h2>How is sunscreen SPF tested?</h2> Once a sunscreen formulation has been developed by a manufacturer it needs to go through testing to ensure it only contains approved ingredients, and ultimately, that it does what it says it does. All sunscreen products available in Australia are <a href="https://www.tga.gov.au/news/news/about-sunscreens">tested according to the Australian Standard to determine the SPF</a>. This is great and provides assurance of safety and quality for the consumer – but the problem is with how this testing is done. Currently, testing sunscreens on humans is the approved international standard to rate the UV protection level of a sunscreen. This testing involves volunteers wearing strictly defined amounts of sunscreen and being exposed to artificial solar <a href="https://www.arpansa.gov.au/understanding-radiation/what-is-radiation/non-ionising-radiation/ultraviolet-radiation">UV radiation</a>. Performance is measured by determining the time it takes for erythema or redness to occur. <a href="https://www.cancer.org.au/about-us/policy-and-advocacy/prevention-policy/national-cancer-prevention-policy/skin-cancer-statistics-and-issues/sunburn">This is, basically, sunburn</a>; based on this, an SPF rating is assigned. <h2>Why is human testing of SPF a problem?</h2> If sunscreens only contain approved ingredients we know are safe, is it really a problem they are tested on humans? Sadly, yes. Human testing involves exposing people to harmful UV radiation, which we know can cause skin and eye damage, <a href="https://www.arpansa.gov.au/understanding-radiation/radiation-sources/more-radiation-sources/sun-exposure">as well as being the leading cause of skin cancer</a>. This alone is <a href="https://www.phrp.com.au/wp-content/uploads/2022/03/PHRP3212205.pdf">unethical and unjustifiable</a>. There are also other issues associated with testing sunscreen on humans. For example, the <a href="https://onlinelibrary.wiley.com/doi/full/10.1111/phpp.12095">use of erythema to determine sunscreen effectiveness is highly subjective</a>, and may differ from one person to another, even for those with the same <a href="https://www.arpansa.gov.au/sites/default/files/legacy/pubs/RadiationProtection/FitzpatrickSkinType.pdf">skin type</a>. This makes the reliability of such testing methods questionable. Further, testing is only done on a small number of people (a minimum of <a href="https://www.tga.gov.au/sites/default/files/australian-regulatory-guidelines-for-sunscreens.pdf">ten people is required in Australia</a>). This is great for exposing as few people as possible to harmful UV radiation to determine a product’s SPF rating – but not so great when it comes to inclusiveness. Testing such a small number of people is not representative. It does not include all skin types and leads to real <a href="https://onlinelibrary.wiley.com/doi/full/10.1111/ics.12333">challenges in achieving reproducible results</a> across different laboratories testing the same product. The testing itself is also very expensive. This adds to the already high cost of buying sunscreens, and potentially limits manufacturers from developing new and better products. These, along with many other issues, highlight the urgency for non-human (in vitro) testing methods of a sunscreen’s effectiveness to be developed. <h2>Human-free SPF testing technology is in development</h2> While efforts have been made to develop non-human testing methods, <a href="https://www.sciencedirect.com/science/article/pii/S0165993622002072">there remain several challenges</a>. <a href="https://www.karger.com/Article/Abstract/292777">These include</a> the materials used to simulate human skin (also known as substrates), difficulties in applying the sunscreen to these substrates, reproducibility of results, and ensuring that results are the same as what we see with human testing. However, scientists at <a href="https://www.rmit.edu.au/">RMIT University</a>, with support from the Australian Radiation Protection and Nuclear Safety Agency (<a href="https://www.arpansa.gov.au/">ARPANSA</a>) and the <a href="https://www.cancervic.org.au/">Cancer Council Victoria</a>, are <a href="https://www.sciencedirect.com/science/article/pii/S0165993622002072">working on a solution to this problem</a>. So far, they have developed a prototype sensor that <a href="https://www.nature.com/articles/s41467-018-06273-3">changes colour when exposed to UV radiation</a>. This <a href="https://www.nature.com/articles/s41467-018-06273-3/figures/5">sensor</a> could be customised for human-free sunscreen testing, for example. Reliable in vitro testing methods will mean in the future, sunscreen manufacturers would be able to quickly make and test new and better sunscreens, without being limited by the time and cost constraints involved with human testing. So the next time you buy a bottle of sunscreen, look to purchase the highest-rated sunscreen of SPF 50+ – and know that work is underway on getting that rating classified in a more ethical way.

Mother dies in her sleep just hours after testing positive to Covid

A family in Sydney have bene left devastated after a mother-of-two died in her sleep just hours after testing positive to Covid. Melaine Leffler was only experiencing minor symptoms of the virus, such as a stuffy nose and are throat, when she tested positive after taking a rapid antigen test. The healthcare worker had received four vaccinations, and was "feeling fine" when she said goodnight to her family on November 19th. Her husband Mick Hogan and their daughters Clemmie, 4, and Lottie, 9 months, had no idea it would be last time they would speak to her, as the 39-year-old mum died in her sleep that night. Her sudden death left her family reeling, as her husband shared the news of her passing on Facebook. “It is with great sadness and a heavy heart that I have to announce to you this way though social media,” Mick wrote. “My loving wife and the mother of 2 beautiful children, Mel Leffler, sadly passed away in her sleep this morning." “She tested positive for Covid last night with a rat test, but only had a runny nose and slightly sore throat. Other than that she was feeling fine.” Melanie’s father Wayne described his daughter as “beautiful, intelligent and loving” person, adding that he and her mother Roz were “deeply shocked and saddened” by her death. “Roz and I lost our beautiful, intelligent and loving 39 y.o. daughter, Mel, overnight,” he wrote in a poignant Facebook post. “To say we’re shocked and deeply saddened would be an understatement. Suddenly, nothing else matters in life other than ensuring the support and wellbeing of Mick and our 2 beautiful granddaughters." “No child should ever pre-decease their parents. It’s just not right." “I awoke hoping Mel’s passing was just a bad dream. I’ve never felt so low. We’re devastated – things will never be the same.” Melanie’s cause of death is yet to be confirmed by a coroner’s report, but her brother Kris Leffler firmly believes it was heart-related. He also revealed that Melanie was inspired to study medical science after a bout of Wilms’ tumour – a rare kidney cancer that primarily affects children – left her with just one kidney.
