These 12 things can reduce your dementia risk – but many Australians don’t know them all

<div class="theconversation-article-body"><a href="https://theconversation.com/profiles/joyce-siette-1377445">Joyce Siette</a>, <a href="https://theconversation.com/institutions/western-sydney-university-1092">Western Sydney University</a> and <a href="https://theconversation.com/profiles/laura-dodds-1378067">Laura Dodds</a>, <a href="https://theconversation.com/institutions/western-sydney-university-1092">Western Sydney University</a> Dementia is a <a href="https://www.abs.gov.au/statistics/health/causes-death/provisional-mortality-statistics/jan-may-2022">leading</a> cause of death in Australia. Although dementia mainly affects older people, it is an avoidable part of ageing. In fact, we all have the power to reduce our risk of developing dementia, no matter your age. Research shows your risk of developing dementia could be <a href="https://www.thelancet.com/article/S0140-6736(20)30367-6/fulltext">reduced by up to 40%</a> (and even higher if you live in a <a href="https://www.thelancet.com/journals/langlo/article/PIIS2214-109X(19)30074-9/fulltext">low or middle-income country</a>) by addressing lifestyle factors such as healthy diet, exercise and alcohol consumption. But the first step to reducing population-wide dementia risk is to understand how well people understand the risk factors and the barriers they may face to making lifestyle changes. Our new <a href="https://www.mdpi.com/2673-9259/2/4/21/htm">paper</a>, published this week in the <a href="https://www.mdpi.com/2673-9259/2/4/21/htm">Journal of Ageing and Longevity</a>, found most older people are aware that dementia is a modifiable condition and that they have the power to change their dementia risk. We also found the key barrier to making brain healthy lifestyle choices was a lack of knowledge, which suggests a public awareness campaign is urgently needed. <h2>What we did</h2> We began by <a href="https://www.mdpi.com/2673-9259/2/4/21/htm">reviewing</a> the published research to identify 12 factors shown to reduce dementia risk. We surveyed 834 older Australians about their awareness of the 12 factors, which were: <ol> <li>having a mentally active lifestyle</li> <li>doing physical activity</li> <li>having a healthy diet</li> <li>having strong mental health</li> <li>not smoking</li> <li>not consuming alcohol</li> <li>controlling high blood pressure</li> <li>maintaining a healthy weight</li> <li>managing high cholesterol</li> <li>preventing heart disease</li> <li>not having kidney disease</li> <li>not having diabetes</li> </ol> <a href="https://www.thelancet.com/article/S0140-6736(20)30367-6/fulltext">The Lancet</a> subsequently published its own list of factors that help reduce dementia risk, which covered much the same territory (but included a few others, such as reducing air pollution, treating hearing impairment and being socially engaged). Of course, there is no way to cut your dementia risk to zero. Some people do all the “right” things and still get dementia. But there is <a href="https://www.thelancet.com/article/S0140-6736(20)30367-6/fulltext">good evidence</a> managing lifestyle factors help make it less likely you will get dementia over your lifetime. Our study shows many older Australians are quite aware, with over 75% able to correctly identify more than four of the factors in our list of 12. However, few were able to name the less well-known risk factors, such as preventing heart disease and health conditions like kidney disease. The good news is that close to half of the sample correctly identified more than six of the 12 protective factors, with mentally active lifestyle, physical activity and healthy diet in the top three spots. <h2>Two key issues</h2> Two things stood out as strongly linked with the ability to identify factors influencing dementia risk. Education was key. People who received more than 12 years of formal schooling were more likely to agree that dementia was a modifiable condition. We are first exposed to health management in our school years and thus more likely to form healthier habits. Age was the other key factor. Younger respondents (less than 75 years old) were able to accurately identify more protective factors compared to older respondents. This is why health promotion initiatives and public education efforts about dementia are vital (such as Dementia Awareness Month and <a href="https://www.memorywalk.com.au/">Memory, Walk and Jog initiatives</a>). <h2>How can these findings be used in practice?</h2> Our findings suggest we need to target education across the different age groups, from children to older Australians. This could involve a <a href="https://onlinelibrary.wiley.com/doi/full/10.1111/ajag.13049">whole system approach</a>, from programs targeted at <a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC5858574/#:%7E:text=Family%20Coaching%20has%20specific%20goals,to%20problem%20solve%20challenging%20situations.">families</a>, to educational sessions for school-aged children, to involving GPs in awareness promotion. We also need to tackle barriers that hinder dementia risk reduction. This means doing activities that motivate you, finding programs that suit your needs and schedule, and are accessible. <h2>What does this mean for you?</h2> Reducing your dementia risk means recognising change starts with you. We are all familiar with the everyday challenges that stop us from starting an exercise program or sticking to a meal plan. There are simple and easy changes we can begin with. Our team has developed a program that can help. We are offering limited <a href="https://www.brainbootcamp.com.au/">free brain health boxes</a>, which include information resources and physical items such as a pedometer. These boxes aim to help rural Australians aged 55 years and over to adopt lifestyle changes that support healthy brain ageing.

Disgraced Olympian sentenced over failed drug plot

An Olympic silver medallist and his younger brother, who tried to smuggle hundreds of kilograms of cocaine worth about $200 million into Australia, have been sentenced a second time. Nathan Baggaley, 48, a former champion kayaker and his brother Dru Baggaley, 42, faced Brisbane supreme court on Monday after pleading guilty to attempting to import a commercial quantity of drugs. Dru and another man were intercepted by the navy in July 2017, after he was found using a seven-metre inflatable boat to pick up 650 kilograms of cocaine from a ship near Australia's east coast. The inflatable boat, which was launched from Brunswick Heads on the NSW north coast, had been bought by Nathan and was registered in his name. The brothers were previously found guilty of attempting to import cocaine by a Brisbane Supreme Court jury in April 2021. Nathan was sentenced to 25 years' imprisonment and his brother 28 years, but they later won appeals against their convictions and were ordered to face the retrial that was supposed to start on October 28, but instead pleaded guilty to the same charge. On Monday, Justice Declan Kelly sentenced Nathan to 13 years in jail and his brother 15 years. With time already served, they are now eligible for parole. During their sentencing hearing, Justice Kelly said there was insufficient evidence to prove Dru knew he was importing cocaine, after the court was told he thought he was collecting tobacco. “Dru was reckless that there was a substantial quantity of a border-controlled drug but there is insufficient evidence that he knew the precise quantity,” Justice Kelly said. He said that Nathan didn't initially know that it was an attempt to import a border-controlled drug until July 30 2018. "From that point in time he was aware of the attempt to import a substantial quantity of a border-controlled drug but was reckless as to the identity of that drug," Justice Kelly said. “It cannot be shown that Nathan knew the drug was cocaine or the precise amount of the drug.” Kelly accepted a defence barrister's submission the facts were profoundly different” compared to their 2021 sentencing, but said that regardless, the importation size was a "“very relevant factor” in his sentencing.

Woman sentenced to life for murdering parents and living with their bodies

A British woman, who murdered her parents and lived with their bodies for four years, was sentenced to life imprisonment on Friday and is not eligible for parole for 36 years. When Essex Police raided Virginia McCullough's house in Great Baddow last September, the 36-year-old confessed that her parents' bodies were in the house and that she had killed them. She admitted to poisoning her father, John McCullough, 70, with prescription medication that she put into his drink, and then a few days later, beat her 71-year-old mother Lois McCullough with a hammer and fatally stabbed her. “I did know that this would kind of come eventually,” she said while handcuffed in body cam footage released by police on Friday. “It’s proper that I serve my punishment.” After McCullough was arrested, she told an officer: “Cheer up, at least you’ve caught the bad guy,” adding that “I know I don’t seem 100 per cent evil.” Further body cam footage showed her at the police station telling officers where to find the tools she used to kill her mother. She had pleaded guilty to murdering her parents at a previous hearing in June 2019. In the words of the prosecution, McCullough kept her father in a “homemade mausoleum” in his bedroom and study, in a structure that was “composed with masonry blocks stacked together.” She wrapped her mother's body in a sleeping bag and put it in a wardrobe on the top floor of the property. In the four years after the murder, she ran up £149,697 ($AU289,792) on credit cards in her parents’ names and continued to spend their pensions. The court heard she cancelled family arrangements and told doctors and relatives that her parents were unwell or away on a trip. Statements from her three unnamed siblings were also read in court, and one said: “our parents were completely blameless victims”. “Virginia always said Mum and Dad were fine and made up lie after lie about their daily activities," another said. Judge Jeremy Johnson said at the sentencing hearing on Friday that McCullough’s actions represented a “gross violation of the trust that should exist between parents and their children.” Judge Johnson said that she had maintained an “elaborate, extensive and enduring web of deceit” over months and years and that he was sure there was a “substantial degree of both pre-meditation and planning," that went into the murder. Essex Police said documents found in the home showed that McCullough was trying desperately” to keep her parents from discovering the poor state of her finances, and gave “false assurances” about her employment and future prospects. “She is an intelligent manipulator who chose to kill her parents callously, without a thought for them or those who continue to suffer as a result of their loss,” said Detective Superintendent Rob Kirby. "The details of this case shock and horrify even the most experienced of murder detectives, let alone any right-thinking member of the public.” Image: Essex Police/ 7NEWS

5 ways to reduce everyday bills

It’s not uncommon to get to the end of the month and be surprised by a figure in your bills. But this surprise needn’t be unpleasant. There is wide a range of simple measures you can employ to reduce your monthly bills without too much effort. Follow these five simple tips and save money. 1. Food and groceries Food can be a problem area in the average Australian’s budget, either because we’re physically eating too much, eating out too much or spending too much money on groceries. But that doesn’t mean you have to transition to a Spartan diet. Here’s how you can save on your grocery bill: <ul> <li>Reduce the amount of times you’re eating out or getting takeout a week</li> <li>Use a shopping list and coupons, pay for groceries (this means you’re less likely to splurge on items that you don’t need) and buy more non-perishable foods to store and save</li> <li>Consider starting a garden and grow your own fruit and veggies</li> </ul> 2. Energy Many people have found their energy bills have been increasingly steady over the past through years, but this doesn’t mean you have to be part of that trend. With a little bit of ingenuity and not a lot of fuss you can make your house energy efficient and enjoy huge power bill savings: <ul> <li>Switch to energy-efficient light bulbs. In many cases these bulbs do cost more than traditional bulbs, but they use much less energy and can last up to 10 times longer</li> <li>Unplug unused electrical devices that are draining electricity</li> <li>Make sure you home is airtight to prevent cold drafts in winter and the loss of cool air in summer. This will also reduce your heating/cooling bills accordingly</li> </ul> 3. Cars As fuel, registration and maintenance costs start to pile up, a car can seem less like a convenience and more like a money pit rolling around on four wheels. That being said, there is a range of ways you can enjoy the access vehicle ownerships provides, without having to pay through your nose: <ul> <li>Underinflated tyres reduces the value of your cars fuel economy significantly, so make sure you take a couple of minutes to check the air pressure and reinflate once a month</li> <li>Consider selling a vehicle if you’re not using it often. Without taking the cost of parking and toll roads into account driving vehicles costs thousands of dollars a year</li> <li>Use more public transport and consider setting up car pools with friends/colleagues</li> </ul> 4. Grooming and beauty Looking and feeling great is important, but it doesn’t necessarily have to be a hugely expensive ordeal. With a little bit of ingenuity, creativity and willingness to not spend $10,000 on that jewel encrusted headdress you can still be the belle/male-belle of the ball without breaking the bank: <ul> <li>Reduce the amount of money you spend on clothing by keeping your eye on sales</li> <li>Consider lower cost alternatives to your favourite beauty products</li> <li>Cut back on the amount of times you have your hair cut and styled</li> </ul> 5. Additional entertainment expenses Your deluxe gym membership might give you access to the power lifting body attack class, but are you really getting the full value for it and the other regular entertainment expenses you’ve signed up for? There are still ways to stay entertained without having to break the bank every week. <ul> <li>Consider cancelling club memberships for places you don’t visit often</li> <li>Investigate free events and inexpensive entertainment ideas like cheap movies Tuesdays</li> <li>Magazine and newspaper subscriptions can also become expensive if you’re not actually reading the papers, as well as pay television services that can be easily eliminated</li> </ul> Image credits: Shutterstock

How cutting edge AI technology is helping doctors reduce waitlists

<div> Artificial intelligence is now being used by Australian specialist doctors to reduce patient wait times and experts say it could be a game changer for the health sector, where some patients are waiting months or even years for an appointment. </div> <div> Leading Australian tech company <a title="https://www.medowhealth.ai/" href="https://www.medowhealth.ai/" data-outlook-id="ad0ccae0-1f97-484e-ba83-d8d566a7608a">Medow Health</a> has developed an AI “co-pilot” technology which automates medical reports for specialist doctors while operating in the background during patient consultations, saving clinicians hours which allows them to see more patients each day. </div> <div> “This technology transforms the way medical reports are formulated and processed, helping specialists reduce their paperwork and freeing up valuable time and resources which can be better spent on patient care,” said Joel Freiberg who co-founded Medow Health with his brother after his own experience with a chronic illness coupled with watching their father who is a respiratory specialist dictate reports until 10pm from the dinner table, prompting them to come up with a more efficient way for clinicians to work. </div> <div> “The idea was to improve what really is an archaic reporting system, which saw specialists taking notes with their back to the patient during consultations or having to speak into a dictaphone to be transcribed later, instead of solely focusing on the patient in front of them,” Mr Freiberg said. </div> <div> The uptake from specialists utilising the new technology has been swift, with doctors reporting the technology is giving them back two to three hours a day, reducing burnout and allowing them to see multiple more patients in that time if they choose. </div> <div> “Instead of your doctor staring into the computer typing notes, they can really concentrate on your needs and wellbeing while the technology does the note taking in the background and creates an almost instant report that the doctor just has to review rather than formulate from scratch,” Mr Freiberg said. </div> <div> Data from the Australian Medical Association on “hidden waitlists” for a specialist outpatient appointment shows some people are languishing for years for an initial consultation - up to 800 days for an initial appointment for an Ear, Nose and Throat Surgeon, up to 898 days for an urgent appointment with a neurosurgeon, while waitlists for a gastroenterologist or ophthalmologist can be as long as five years and up to 36 months to see a paediatrician. </div> <div> Mr Freiberg said the new cutting edge technology could supercharge a reduction in waitlists and speed up the appointment process. </div> <div> “We’re not trying to replace doctors, we’re trying to help them. Manually producing medical reports is a time-consuming and complex process that requires extensive paperwork and hours of labour-intensive work,” he said. </div> <div> “By using cutting edge AI specific to each medical specialty to examine patient interactions, formulate reports, and provide valuable insights we can enable doctors to do what they do best - focus on patient care,” Mr Freiberg said. </div> <div> Chris O’Brien Life House Chief Executive and medical oncologist Professor Michael Boyer who is on the Medow Health Clinical Advisory Council agreed the technology will improve patient care and help reduce waiting lists. </div> <div> "Any piece of technology that allows doctors to focus on the patient, helps deliver better care,” Prof Boyer said. </div> <div> "This technology helps the health professional to really turn their attention to the patient and what matters, instead of worrying about what notes they need and what letters they need to write. It allows them to focus on what is important. </div> <div> "There's no doubt this technology saves time and while it might only allow a single doctor to see an extra one of two patients a day, if you multiply that across the health system then it makes a big difference,” Prof Boyer said. </div> <div> Engagement with Medow Health is taking off in Australia, with the company reporting growth of more than 50 percent month on month across 15 different specialties including Cardiology, Gastroenterology, ENT, Geriatric, Orthopaedic Surgery, Paediatric, Neurology, General Surgery and Breast Surgeons, with some of Australia’s leading specialist doctors among the investors and Medtech Entrepreneurs to invest in its recent Seed round. </div> <div> About Medow Health AI </div> <div> Medow Health AI is a pioneering Australian based healthcare technology company dedicated to revolutionising the medical industry through the power of artificial intelligence to streamline processes, improve patient care, and enhance overall efficiency in healthcare settings. </div> <div> The company was founded by Joel Freiberg and soon after his brother Josh and former CTO and colleague Andrew joined as co-founders using their combined 30 years experience in technology and software to help build the business into the leading Specialist AI platform it is today. </div> <div> Joel lives with Crohn’s disease and has experienced long waits to see a specialist. The pair recognised there was a need for change growing up as they watched their father, a respiratory physician spend endless hours doing admin after work. </div> <div> The company has just completed a $1M funding round in the first half of 2024, grown the team to 10 full time employees and signed a partnership with Magentus the owner of leading specialist electronic medical record systems Genie & Gentu (who Medow Health integrates with).

New study finds epilepsy drug could reduce sleep apnoea symptoms

New research has found that a drug used for epilepsy could be used to reduce the symptoms of sleep apnoea. Obstructive sleep apnoea, which affects about one in 20 people, according to the National Institute for Health and Care Excellence in England, includes symptoms like snoring and it causes a person's breathing to start and stop during the night, with many requiring an aid to help keep their airways open. An international study has identified that taking sulthiame, a drug sold under the brand name Ospolot in Europe, may help prevent patients' breathing from temporarily stopping. This provides an additional option for those unable to use mechanical breathing aids like the Cpap machines. “The standard treatment for obstructive sleep apnoea is sleeping with a machine that blows air through a face mask to keep the airways open. Unfortunately, many people find these machines hard to use over the long term, so there is a need to find alternative treatments,” Prof Jan Hedner from Sahlgrenska university hospital and the University of Gothenburg in Sweden said. Researchers conducted a randomised controlled trial of almost 300 obstructive sleep apnoea patients across Europe, who did not use Cpap machines. They were divided into four groups and given either a placebo or different strengths of sulthiame. The study measured patients’ breathing, oxygen levels, heart rhythm, eye movements, as well as brain and muscle activity while asleep. It found after 12 weeks, those taking sulthiame had up to 50% fewer occasions where their breathing stopped, and higher levels of oxygen in their blood. However, a bigger study needs to be done to confirm the beneficial effects on a larger group. The findings, were presented at the European Respiratory Society Congress in Vienna, Austria. Erika Radford, the head of health advice at Asthma + Lung UK said the findings were a positive step forward in moving away from having to rely on mechanical breathing equipment. “This potential alternative to the current main treatment would make it easier for people to manage their condition,” she said.

Cranberry juice really can help with UTIs – and reduce reliance on antibiotics

<div class="theconversation-article-body"> <a href="https://theconversation.com/profiles/christian-moro-121754">Christian Moro</a>, <a href="https://theconversation.com/institutions/bond-university-863">Bond University</a> and <a href="https://theconversation.com/profiles/charlotte-phelps-1187658">Charlotte Phelps</a>, <a href="https://theconversation.com/institutions/bond-university-863">Bond University</a> Cranberry juice has been <a href="https://www.ncbi.nlm.nih.gov/books/NBK92762/">used medicinally for centuries</a>. Our new research indicates it should be a normal aspect of urinary tract infection (UTI) management today. While some benefits of cranberry compounds for the prevention of UTIs have been suspected for <a href="https://theconversation.com/cranberry-juice-can-prevent-recurrent-utis-but-only-for-some-people-203926">some time</a>, it hasn’t been clear whether the benefits from cranberry juice were simply from drinking <a href="https://bjgp.org/content/70/692/e200">more fluid</a>, or something in the fruit itself. For our <a href="https://www.sciencedirect.com/science/article/pii/S2405456924001226">study</a>, published this week, we combined and collectively assessed 3,091 participants across more than 20 clinical trials. Our analysis indicates that increasing liquids reduces the rate of UTIs compared with no treatment, but cranberry in liquid form is even better at reducing UTIs and antibiotic use. <h2>Are UTIs really that bad?</h2> Urinary tract infections affect more than <a href="https://journals.sagepub.com/doi/pdf/10.1177/1756287219832172">50% of women</a> and <a href="https://bjgpopen.org/content/bjgpoa/5/2/bjgpopen20X101140.full.pdf">20% of men</a> in their lifetime. Most commonly, UTIs are caused from the bug called Escherichia coli (E.coli). This bug lives harmlessly in our <a href="https://www.ncbi.nlm.nih.gov/books/NBK562895/">intestines</a>, but can cause infection in the <a href="http://doi.org/10.33235/anzcj.30.1.4-10">urinary tract</a>. This is why, particularly for women, it is recommended people wipe from front to back after using the toilet. An untreated UTI can move up to the kidneys and cause even more serious illness. Even when not managing infection, many people are anxious about contracting a UTI. Sexually active women, pregnant women and older women may all be at <a href="https://www.ncbi.nlm.nih.gov/books/NBK436013/">increased risk</a>. <h2>Why cranberries?</h2> To cause a UTI, the bacteria need to attach to the wall of the <a href="https://www.nature.com/articles/s41598-023-44916-8">urinary bladder</a>. Increasing fluids helps to flush out bacteria before it attaches (or makes its way up into the bladder). Some beneficial compounds in cranberry, such as <a href="https://www.cochrane.org/CD001321/RENAL_cranberries-preventing-urinary-tract-infections">proanthocyanidins</a> (also called condensed tannins), prevent the bacteria from attaching to the wall itself. While there are treatments, over 90% of the bugs that cause UTIs exhibit some form of <a href="https://www.who.int/news-room/fact-sheets/detail/antimicrobial-resistance">microbial resistance</a>. This suggests that they are rapidly changing and some cases of UTI might be left <a href="https://www.scientificamerican.com/article/antibiotic-resistant-utis-are-common-and-other-infections-may-soon-be-resistant-too/">untreatable</a>. <h2>What we found</h2> Our analysis <a href="https://www.sciencedirect.com/science/article/pii/S2405456924001226">showed</a> a 54% lower rate of UTIs from cranberry juice consumption compared to no treatment. This means that significantly fewer participants who regularly consumed cranberry juice (most commonly around 200 millilitres each day) reported having a UTI during the periods assessed in the studies we analysed. Cranberry juice was also linked to a 49% lower rate of antibiotic use than placebo liquid and a 59% lower rate than no treatment, based on analysis of indirect and direct effects across six studies. The use of cranberry compounds, whether in drinks or tablet form, also reduced the prevalence of symptoms associated with UTIs. While some studies we included presented conflicts of interest (such as receiving funding from cranberry companies), we took this “high risk of bias” into account when analysing the data. <h2>So, when can cranberry juice help?</h2> We found three main benefits of cranberry juice for UTIs. 1. Reduced rates of infections Increasing fluids (for example, drinking more water) reduced the prevalence of UTIs, and taking cranberry compounds (such as tablets) was also beneficial. But the most benefits were identified from increasing fluids and taking cranberry compounds at the same time, such as with cranberry juice. 2. Reduced use of antibiotics The data shows cranberry juice lowers the need to use antibiotics by 59%. This was identified as fewer participants in randomised cranberry juice groups required antibiotics. Increasing fluid intake also helped reduce antibiotic use (by 25%). But this was not as useful as increasing fluids at the same time as using cranberry compounds. Cranberry compounds alone (such as tablets without associated increases in fluid intake) did not affect antibiotic use. 3. Reducing symptoms Taking cranberry compounds (in any form, liquid or tablet) reduced the symptoms of UTIs, as measured in the overall data, by more than five times. <h2>Take home advice</h2> While cranberry juice cannot treat a UTI, it can certainly be part of UTI management. If you suspect that you have a UTI, see your GP as soon as possible.<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/235314/count.gif?distributor=republish-lightbox-basic" alt="The Conversation" width="1" height="1" /> <a href="https://theconversation.com/profiles/christian-moro-121754">Christian Moro</a>, Associate Professor of Science & Medicine, <a href="https://theconversation.com/institutions/bond-university-863">Bond University</a> and <a href="https://theconversation.com/profiles/charlotte-phelps-1187658">Charlotte Phelps</a>, Senior Teaching Fellow, Medical Program, <a href="https://theconversation.com/institutions/bond-university-863">Bond University</a> Image credits: Shutterstock This article is republished from <a href="https://theconversation.com">The Conversation</a> under a Creative Commons license.

Russell Hill's daughter shares her outrage over Greg Lynn's sentence

Russell Hill's daughter has expressed her anger over the jury's verdict of former pilot Greg Lynn, who was found not guilty for Hill's murder. Greg Lynn faced a lengthy trial over the deaths of campers Russell Hill and Carol Clay, but after a week of jury deliberations, was only <a href="https://oversixty.com.au/finance/legal/shocking-verdict-in-trial-of-murdered-campers" target="_blank" rel="noopener">found guilty</a> for the murder of Carol and was cleared of charges relating to Russell's death. Following the shock verdict, Hill's daughter Debbi, said she was “angry” at the jury and that she felt her father didn’t get the justice he deserved. “It’s new, we’ve only just found out, but the more I think about it, the more angry I get at the fact that it didn’t have to be this way,” Ms Hill told 60 Minutes on Sunday. “My dad was not a violent person in any way. He wouldn’t have provoked anything.” Ms Hill went on to say that she thinks about what happened to her father every day. “I’m just really angry that he went camping that day, that time, that he is the person he is and he happened to be right there with my dad and Carol, and this is what happened,” she said. “I think it was just really bad luck for Dad and Carol that they were there at the time, but it wouldn’t have happened if he [Lynn] wasn’t such an awful person.” After the trial concluded, more information has come to light about Lynn's past after non-publication orders were lifted. His first wife Lisa Lynn, 34, was found dead in the front yard of her home in 1999, with a coroner’s report indicating a blood-alcohol level of 0.21 and high levels of anti-depression medication present in her system at the time of her death. No suicide note was ever found and Lynn was never charged over her death, however detectives are now looking to have the Victorian coroner conduct a full inquest into the 1999 death. Ms Hill said it was quite concerning to learn about Lynn’s history, saying, “I hope he doesn’t get away with this, but I’ve lost a bit of faith in the whole system.” “I’m not trusting of it now. We’ll have to wait and see. He’s just such a terrible person.” Image credits: Facebook / Victoria Police

<div class="theconversation-article-body"><a href="https://theconversation.com/profiles/adam-taylor-283950">Adam Taylor</a>, <a href="https://theconversation.com/institutions/lancaster-university-1176">Lancaster University</a> This week has seen another barrage of <a href="https://www.theguardian.com/uk-news/2024/jan/22/uk-weather-storm-jocelyn-to-follow-isha-with-more-strong-winds-and-heavy-rain">unsettled weather</a> sweep across the UK, with many flights delayed or cancelled. Some of those who were fortunate enough to take off found themselves arriving at destinations that weren’t on their boarding passes – such as passengers travelling from Stansted to Newquay who eventually diverted to <a href="https://uk.news.yahoo.com/storm-isha-creates-flight-diversion-142821278.html">Malaga</a>. One thing that was consistently described by passengers was that parts of the flights and the attempted landings were some of the most unnerving they’d ever experienced, due to turbulence. Turbulence results from uneven air movement, which is <a href="https://agupubs.onlinelibrary.wiley.com/doi/10.1029/2023GL103814">increasing</a> in frequency. If you turn your hair dryer on at home and hold it still, the air moves at a constant rate, but once you begin drying your hair and moving the hairdryer around, the air movement becomes uneven, that is to say, turbulent. Although turbulence may be unnerving and make you feel unwell, it is important to recognise that it is very common and typically <a href="https://pubmed.ncbi.nlm.nih.gov/18018437/">nothing to worry about</a> if you’re in your seat with your seatbelt fastened. <h2>How the body detects and responds to turbulence</h2> The body recognises itself within any environment. Its relationship with objects in terms of distance and direction is called <a href="https://www.sciencedirect.com/science/article/abs/pii/B9780123750006003414">spatial orientation</a>. When flying, this is typically moving forwards, ascending, some turns and a descent. However, turbulence disrupts this relationship and confuses the sensory information being received by the brain – it makes the body want to respond or recalibrate. Our inner ears play a pivotal role in all this. It consists of complex apparatuses that undertake more than hearing. These include the cochlea, <a href="https://www.ncbi.nlm.nih.gov/books/NBK279394/">three semi-circular canals</a>, <a href="https://radiopaedia.org/articles/utricle-ear?lang=gb">the utricle</a> and <a href="https://radiopaedia.org/articles/saccule-ear-1?lang=gb">the saccule</a>. The cochlea is responsible for hearing. It converts <a href="https://www.ncbi.nlm.nih.gov/books/NBK531483/">sound energy into electrical energy</a> that is then “heard” by the brain. The remaining structures are responsible for the balance and position of the head and body. The semi-circular canals are positioned in a vertical (side to side), horizontal and front-to-back plane, detecting movement in a nodding, shaking and touching ear-to-shoulder direction. Attached to these canals are <a href="https://www.ncbi.nlm.nih.gov/books/NBK532978/">the utricle and saccule</a>, which can detect <a href="https://www.ncbi.nlm.nih.gov/books/NBK10792/">movement</a> and <a href="https://www.cell.com/current-biology/pdf/S0960-9822(05)00837-7.pdf">acceleration</a>. All of these apparatuses use microscopic hair cells in a specialised fluid called <a href="https://www.ncbi.nlm.nih.gov/books/NBK531505/">endolymph</a> that flows with the head to create a sense of movement. When the plane encounters turbulence, this fluid moves around, but unpredictably. It takes <a href="https://www.ncbi.nlm.nih.gov/books/NBK518976/">about ten to 20 seconds</a> for the fluid to recalibrate its position, while the brain struggles to understand what is going on. When the aircraft hits turbulence, the balance apparatus <a href="https://www.frontiersin.org/articles/10.3389/fneur.2023.949227/full">cannot distinguish</a> the movement of the plane from that of the head, so the brain interprets the aircraft movement as that of the head or body. But this doesn’t match the visual information being received, which causes sensory confusion. The reason the inner ear causes so much confusion is because during flights you are devoid of your primary sensory tool relative to the external environment – your sight and the horizon. Eighty per cent of <a href="https://www.ncbi.nlm.nih.gov/books/NBK518976/">spatial information</a> comes from your eyes during flight. However, you only have the seat in front of you or the cabin as a reference point, which means your inner ear becomes the dominant sensory message to the brain during turbulence and disrupts the <a href="https://www.ncbi.nlm.nih.gov/books/NBK545297/">“vestibulo-ocular reflex”</a>. This reflex keeps your vision <a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC4130651/">aligned</a> with your balance or expected position. Vision is the <a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC6777262/">most valued</a> of the senses and one-third of the brain is attributed to its function, reinforcing its importance in spatial orientation. This sensory mixed messaging often results in things like dizziness and sweating as well as gastrointestinal symptoms, such as <a href="https://www.airmedicaljournal.com/article/S1067-991X(02)70038-2/fulltext">nausea and vomiting</a>. Motion sickness can be triggered by turbulence and although research into specific airsickness is limited, other modes that induce motion sickness suggest that <a href="https://pubmed.ncbi.nlm.nih.gov/16018346/">women</a> are <a href="https://pubmed.ncbi.nlm.nih.gov/26466829/">more susceptible</a> than men, particularly in the <a href="https://pubmed.ncbi.nlm.nih.gov/16235881/">early stages</a> of the menstrual cycle. The turbulence also causes an increase in your heart rate, which is already higher than normal when flying because of a <a href="https://pubmed.ncbi.nlm.nih.gov/15819766/">decrease in oxygen saturation</a>. <h2>What about the pilots?</h2> Commercial pilots accrue thousands of hours at the controls, they are subject to the same forces as the passengers. Over time, they can <a href="https://academic.oup.com/milmed/article/180/11/1135/4160573">adapt to these forces</a> and <a href="https://pubmed.ncbi.nlm.nih.gov/15828634/">experiences</a>, but they also have a couple of additional resources that most passengers don’t. They have the view out of the cockpit windows, so have a horizon to use as a reference point and can see what lies immediately ahead. If it is cloudy or visibility is low, their instruments provide additional visual <a href="https://www.faa.gov/sites/faa.gov/files/regulations_policies/handbooks_manuals/aviation/phak/19_phak_ch17.pdf">reference</a> to the position of the aircraft. This doesn’t mean they are immune to the effects of turbulence, with some studies reporting up to <a href="https://pubmed.ncbi.nlm.nih.gov/26540704/">71% of trainee pilots</a> reporting episodes of airsickness. <h2>How to reduce the discomfort</h2> A window seat can help, or even looking out the window. This gives the brain some sensory information through visual pathways, helping calm the brain in response to the vestibular information it is receiving. If you can get one, a seat towards the front or over the wing reduces the effects of turbulence. Deep or rhythmical breathing can help reduce motion sickness induced by turbulence. Focusing on your breathing <a href="https://pubmed.ncbi.nlm.nih.gov/25945662/">calms the nervous system</a>. Don’t reach for the alcohol. While you may feel it calms your nerves, if you hit turbulence it’s going to interfere with your <a href="https://pubmed.ncbi.nlm.nih.gov/7610847/">visual and auditory processing</a> and increase the likelihood of vomiting. If you suffer from motion sickness and are worried about turbulence while flying, then there are also <a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC6241144/">drugs that can help</a>, including certain <a href="https://www.nhs.uk/medicines/cinnarizine/about-cinnarizine/">antihistamines</a>. Finally, it’s important to remember that although turbulence can be unpleasant, aircraft are designed to withstand the forces it generates and many passengers, even frequent fliers, will rarely encounter the most severe categories of turbulence because pilots actively plan routes to avoid it.<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/221780/count.gif?distributor=republish-lightbox-basic" alt="The Conversation" width="1" height="1" /> <a href="https://theconversation.com/profiles/adam-taylor-283950">Adam Taylor</a>, Professor and Director of the Clinical Anatomy Learning Centre, <a href="https://theconversation.com/institutions/lancaster-university-1176">Lancaster University</a> Image credits: Shutterstock This article is republished from <a href="https://theconversation.com">The Conversation</a> under a Creative Commons license.

Want to reduce your dementia risk? Eat these 4 foods, says new study

If you are what you eat, this might make you hungrier for foods that are bright in every sense. Research has shown that living, vibrant foods can slow down aging at a cellular level; while fruit and vegetables in particular have been associated with lower incidence of cognitive decline as individuals age. However, research has been relatively lacking on just how much of these brain-healthy foods you really need and which fruit and vegetables are best for the job. In collaboration with public health experts at Harvard University, medical researchers at China’s Zhejiang University School of Medicine conducted a meta-analysis that’s slated to be published in the June 2024 issue of The Journal of Nutrition, Health, and Aging. They combined data from two large-scale population-representative studies that analysed the diets and cognitive function of more than 10,000 participants ages 55 and older from China and the US. <h2>What daily diets revealed</h2> The data included diet questionnaires that honed in on the average of participants’ total daily intake of several different types of foods, including fruit and vegetables, and also broke them down into sub-types like green leafy vegetables and berries. Over a period of five years, the participants also took part in activities designed to assess their cognitive function and the average rate of cognitive decline. Overall, participants who included the most fruit and vegetables in their daily diets performed best on the brain tests and maintained those results over time. This suggested that both fruit and vegetables had protective elements that slowed cognitive decline. <h2>Vegetables that help protect cognition</h2> Interestingly, certain types of vegetables appeared to be more beneficial than others—say the researchers: “Our findings support the potential beneficial roles of VF, especially cruciferous vegetables, green leafy vegetables, and red and yellow vegetables, in maintaining cognitive function and slowing cognitive decline in middle-aged and older adults.” The researchers pointed to several reasons these particular vegetables might have shown a substantial impact, including anti-inflammatory and antioxidation nutrients like flavonoids and various vitamins or even gut improvements that have been shown to help improve or protect cognition. While beans didn’t figure prominently in both studies, they showed a protective element in the US study, so they are also worth keeping on your plate. (Beans are also thought to be one of the top foods for longevity.) <h2>Fruit that pack a punch</h2> As for fruit, while some didn’t show as much of a protective effect across the board, berries and apples are two examples of fruit that experts have previously said provide major polyphenol and antioxidant effect. Participants whose brains maintained performance were shown to have eaten three or more servings of vegetables and two or more servings of fruit per day. This is on par with the five servings of vegetables and two servings of fruit recommended we eat every day.

Mind

Australians lose $5,200 a minute to scammers. There’s a simple thing the government could do to reduce this. Why won’t they?

<div class="theconversation-article-body"><a href="https://theconversation.com/profiles/peter-martin-682709">Peter Martin</a>, <a href="https://theconversation.com/institutions/crawford-school-of-public-policy-australian-national-university-3292">Crawford School of Public Policy, Australian National University</a> What if the government was doing everything it could to stop thieves making off with our money, except the one thing that could really work? That’s how it looks when it comes to <a href="https://www.scamwatch.gov.au/types-of-scams">scams</a>, which are attempts to trick us out of our funds, usually by getting us to hand over our identities or bank details or transfer funds. Last year we lost an astonishing <a href="https://www.accc.gov.au/media-release/scam-losses-decline-but-more-work-to-do-as-australians-lose-27-billion">A$2.74 billion</a> to scammers. That’s more than $5,200 per minute – and that’s only the scams we know about from the 601,000 Australians who made reports. Many more would have kept quiet. If the theft of $5,200 per minute seems over the odds for a country Australia’s size, a comparison with the United Kingdom suggests you are right. In 2022, people in the UK lost <a href="https://www.ukfinance.org.uk/system/files/2023-05/Annual%20Fraud%20Report%202023_0.pdf">£2,300</a> per minute, which is about A$4,400. The UK has two and a half times Australia’s population. It’s as if international scammers, using SMS, phone calls, fake invoices and fake web addresses are targeting Australia, because in other places it’s harder. If we want to cut Australians’ losses, it’s time to look at rules about to come into force in the UK. <h2>Scams up 320% since 2020</h2> The current federal government is doing a lot – almost everything it could. Within a year of taking office, it set up the <a href="https://www.accc.gov.au/national-anti-scam-centre">National Anti-Scam Centre</a>, which coordinates intelligence. Just this week, the centre reported that figure of $2.74 billion, which is down 13% on 2022, but up 50% on 2021 and 320% on 2020. It’s planning “<a href="https://treasury.gov.au/consultation/c2023-464732">mandatory industry codes</a>” for banks, telecommunication providers and digital platforms. But the code it is proposing for banks, set out in a <a href="https://treasury.gov.au/sites/default/files/2023-11/c2023-464732-cp.pdf">consultation paper</a> late last year, is weak when compared to overseas. <h2>Banks are the gatekeepers</h2> Banks matter, because they are nearly always the means by which the money is transferred. Cryptocurrency is now much less used after the banks agreed to limit payments to high risk exchanges. Here’s an example of the role played by banks. A woman the Consumer Action Law Centre is calling <a href="https://consumeraction.org.au/wp-content/uploads/2024/02/Joint-submission-CALC-CHOICE-ACCAN-31012024-Scams-Mandatory-code-treasury-consultA.pdf">Amelia</a> tried to sell a breast pump on Gumtree. The buyer asked for her bank card number and a one-time PIN and used the code to whisk out $9,100, which was sent overseas. The bank wouldn’t help because she had provided the one-time PIN. Here’s another. A woman the Competition and Consumer Commission is calling <a href="https://www.accc.gov.au/system/files/Targeting%20scams%202022.pdf">Niamh</a> was contacted by someone using the National Australia Bank’s SMS ID. Niamh was told her account was compromised and talked through how to transfer $300,000 to a “secure” account. After she had done it, the scammer told her it was a scam, laughed and said “we are in Brisbane, come find me”. <h2>How bank rules protect scammers</h2> And one more example. Former University of Melbourne academic <a href="https://www.researchgate.net/publication/377766055_Scams_Blaming_the_Victims">Kim Sawyer</a> (that’s his real name, he is prepared to go public) clicked on an ad for “St George Capital” displaying the dragon logo of St. George Bank. He was called back by a man using the name of a real St. George employee, who persuaded him to transfer funds from accounts at the AMP, Citibank and Macquarie to accounts he was told would be in his and his wife’s name at Westpac, ANZ, the Commonwealth and Bendigo Banks. They lost <a href="https://www.afr.com/wealth/personal-finance/i-lost-2-5m-of-my-super-to-scammers-20240423-p5flzp">$2.5 million</a>. Sawyer says none of the banks – those that sent the funds or those that received them – would help him. Some cited “<a href="https://www.choice.com.au/money/financial-planning-and-investing/stock-market-investing/articles/st-george-capital-investment-scam">privacy</a>” reasons. The Consumer Action Law Centre says the banks that transfer the scammed funds routinely tell their customers “it’s nothing to do with us, you transferred the money, we can’t help you”. The banks receiving the funds routinely say “you’re not our customer, we can’t help you”. That’s here. Not in the UK. <h2>UK bank customers get a better deal</h2> In Australia in 2022, only <a href="https://download.asic.gov.au/media/mbhoz0pc/rep761-published-20-april-2023.pdf">13%</a> of attempted scam payments were stopped by banks before they took place. Once scammed, only 2% to 5% of losses (depending on the bank) were reimbursed or compensated. In <a href="https://www.psr.org.uk/information-for-consumers/app-fraud-performance-data/">the UK</a>, the top four banks pay out 49% to 73%. And they are about to pay out much more. From October 2024, reimbursement will be compulsory. Where authorised fast payments are made “because of deception by fraudsters”, the banks will have to reimburse <a href="https://www.thomsonreuters.com/en-us/posts/investigation-fraud-and-risk/app-fraud-uk">the lot</a>. Normally the bills will be split <a href="https://www.psr.org.uk/news-and-updates/latest-news/news/psr-confirms-new-requirements-for-app-fraud-reimbursement/">50:50</a> between the bank transferring the funds and the bank receiving them. Unless there’s a need for further investigations, the payments must be made within five days. The <a href="https://www.psr.org.uk/media/as3a0xan/sr1-consumer-standard-of-caution-guidance-dec-2023.pdf">only exceptions</a> are where the consumer seeking reimbursement has acted fraudulently or with gross negligence. The idea behind the change – pushed through by the Conservative government now led by UK Prime Minister Rishi Sunak – is that if scams are the banks’ problem, if they are costing them millions at a time, they’ll stop them. <a href="https://www.thepost.co.nz/business/350197309/banks-given-fraud-ultimatum">New Zealand</a> is looking at doing the same thing, <a href="https://www.biocatch.com/blog/mas-shared-responsibility-fraud-losses">as is Singapore</a>. But here, the treasury’s discussion paper on its mandatory codes mentions reimbursement <a href="https://treasury.gov.au/sites/default/files/2023-11/c2023-464732-cp.pdf">only once</a>. That’s when it talks about what’s happening in the UK. Neither treasury nor the relevant federal minister is proposing it here. <h2>Australia’s approach is softer</h2> Assistant Treasurer Stephen Jones is in charge of Australia’s rules. Asked why he wasn’t pushing for compulsory reimbursement here, Jones said on Monday <a href="https://ministers.treasury.gov.au/ministers/stephen-jones-2022/transcripts/interview-mark-gibson-abc-perth">prevention was better</a>. <blockquote> I think a simplistic approach of just saying, ‘Oh, well, if any loss, if anyone incurs a loss, then the bank always pay’, won’t work. It’ll just make Australia a honeypot for these international crime gangs, because they’ll say, well, ‘Let’s, you know, focus all of our activity on Australia because it’s a victimless crime if banks always pay’. </blockquote> Telling banks to pay would certainly focus the minds of the banks, in the way they are about to be focused in the UK. The <a href="https://www.ausbanking.org.au/submissions/">Australian Banking Association</a> hasn’t published its submission to the treasury review, but the <a href="https://consumeraction.org.au/scams-mandatory-industry-codes-consultation-paper/">Consumer Action Law Centre</a> has. It says if banks had to reimburse money lost, they’d have more of a reason to keep it safe. In the UK, they are about to find out. If Jones is right, it might be about to become a honeypot for scammers. If he is wrong, his government will leave Australia even further behind when it comes to scams – leaving us thousands more dollars behind per day.<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/228867/count.gif?distributor=republish-lightbox-basic" alt="The Conversation" width="1" height="1" /> <a href="https://theconversation.com/profiles/peter-martin-682709">Peter Martin</a>, Visiting Fellow, <a href="https://theconversation.com/institutions/crawford-school-of-public-policy-australian-national-university-3292">Crawford School of Public Policy, Australian National University</a> Image credits: Getty Images This article is republished from <a href="https://theconversation.com">The Conversation</a> under a Creative Commons license.

Property tycoon sentenced to death over $27 billion fraud

A Vietnamese billionaire was sentenced to death on Thursday in one of the biggest corruption cases in history, an estimated $27 billion in damages - a figure equivalent to six percent of the country’s 2023 GDP. Truong My Lan, chair of major developer Van Thinh Phat, was found guilty of embezzlement, after looting from one of the country's biggest banks, Saigon Commercial Bank (SCB) for over a decade. “The defendant’s actions... eroded people’s trust in the leadership of the (Communist) Party and state,” the verdict read at the trial in Ho Chi Minh City. After a five-week trial, 85 others were also charged for their involvement in the fraud, with charges ranging from from bribery and abuse of power to appropriation and violations of banking law. Four were given life imprisonment, while others received jail terms ranging between 20 years and three years suspended. Lan's husband was Hong Kong billionaire Eric Chu Nap Kee, was sentenced to nine years in prison. Lan and the others were arrested as part of a national corruption crackdown. Lan was initially believed to have embezzled $12.5 billion, but on Thursday prosecutors have said that the total damages caused by the fraud now amounted to $27 billion. The property tycoon was convicted of taking out $44bn in loans from the bank, according to the BBC, with prosecutors saying that $27 billion of this may never be recovered. The court ordered Lan to to pay almost the entire damages sum in compensation. It is also <a href="https://www.bbc.com/news/world-asia-68778636" target="_blank" rel="noopener">reported</a> that she is one of very few women in Vietnam to be sentenced to death for a white collar crime. “In my desperation, I thought of death,” Lan said in her final remarks to the court, according to state media. “I am so angry that I was stupid enough to get involved in this very fierce business environment -- the banking sector -- which I have little knowledge of.” Police have identified around 42,000 victims of the scam, and many of them were unhappy with the verdict. One 67-year-old Hanoi resident told the AFP that she had hoped Lan would receive a life sentence so she could fully witness the devastating impact of her actions. “Many people worked hard to deposit money into the bank, but now she’s received the death sentence and that’s it for her,” they said. “She can’t see the suffering of the people.” The resident has so far been unable to retrieve the $120,000 she invested with SCB. Police have said that many of the victims are SCB bondholders, who cannot withdraw their money and have not received interest or principal payments since Lan’s arrest. Authorities have also reportedly seized over 1000 properties belonging to Lan. Image: Twitter

"Reduced me to tears": King Charles' candid admission

King Charles has made a candid admission as he returned to his public engagement in over two months as he faces ongoing treatment. The royal joined a meeting of the Privy Council at Buckingham Palace followed by an audience with the British Prime Minister, Rishi Sunak. Palace sources have said that the two events were a sign of “State business, as usual” since his <a style="font-family: -apple-system, BlinkMacSystemFont, 'Segoe UI', Roboto, Oxygen, Ubuntu, Cantarell, 'Open Sans', 'Helvetica Neue', sans-serif;" href="https://www.oversixty.com.au/health/caring/palace-reveals-king-charles-serious-health-diagnosis" target="_blank" rel="noopener">shock cancer diagnosis</a> over two weeks ago, according to The Sun. The monarch, donning a navy pinstripe suit, appeared in good spirits as he shook hands with the UK prime minister and sat down for his first private audience with him since December. “Good evening Your Majesty, very nice to see you," Sunak told the King. “Bit of a gap,” Charles responded. Sunak replied: “A bit, but wonderful to see you looking so well.” The King also showed his playful side as he joked about the check-up process: “well, it’s all done by mirrors," he said and they both laughed. “Well, we are all behind you, the country is behind you," Sunak replied. “I’ve had so many wonderful messages and cards. Reduced me to tears most of the time,” Charles told him. “I can imagine, as I said, everyone is behind you, and it’s been nice to see the spotlight that it’s shone on the work the charities do in this area,” Sunak responded. “I hear there been a lot more interest on those main wonderful cancer charities many of which I’ve been patron for years," Charles added. “They’ve done incredible work up and down the country, nice to be recognised," Sunak replied. The King's last public engagement was a trip to the Royal Courts of Justice on December 14th. His last in-person engagement was an investiture at Windsor Castle on December 19. On Wednesday he held a Privy Council meeting and swore in new member Michael Tomlinson, Minister of State for Illegal Migration. This week, he’s been in London and Windsor Castle, but he is expected to continue getting cancer treatment at Windsor and Highgrove in the coming weeks. Image: Getty

Elderly woman reduced to tears by irate postie

Australia Post is investigating an incident of extreme road rage, after a postie reduced an elderly woman to tears. The postman was driving a three-wheeled electric delivery vehicle on the Gold Coast on Monday morning, when an elderly woman almost struck him on a roundabout. The mailman then instructed the woman to pull over, and began berating her until she burst into tears. The altercation was filmed by a passerby, who attempted to intervene to assist the older woman, an 80-year-old named Kay. “You’re supposed to give way at the roundabout,” the man is heard yelling in footage of the incident aired by Nine News. <iframe style="border: none; overflow: hidden;" src="https://www.facebook.com/plugins/video.php?height=314&href=https%3A%2F%2Fwww.facebook.com%2F9NewsGoldCoast%2Fvideos%2F1680294369165021%2F&show_text=false&width=560&t=0" width="560" height="314" frameborder="0" scrolling="no" allowfullscreen="allowfullscreen"></iframe> “You’re supposed to stop at the roundabout." “Why were you not seeing me?” Bystander Melissa Burrows ran to the aid of Kay, who was visibly upset by the altercation, with Burrows asking the postie to tone down his tirade. “She’s an older lady,” Ms Burrows is heard telling the postie. “She’s scared. Please stop.” “I didn’t see you,” Kay told the postie. Ms Burrows then threatens to call the police on the postie, who responds with a “go away”. “Leave her alone and let her go,” she said. “Can you just slow down next time, please?” the postie asks the elderly woman. “I’m so sorry I didn’t see you,” Kay reaffirms. Speaking to Melissa after the postie drove away, Kay said, “I didn’t even touch him, but I didn’t see him either. I can’t believe how he’s reacted.” Ms Burrows later told the broadcaster the incident was “absolutely horrifying” and a “tirade of incredible abuse”. Australia Post told <a href="https://www.news.com.au/technology/motoring/on-the-road/tirade-of-incredible-abuse-furious-postie-unleashes-on-elderly-gold-coast-driver/news-story/2c9985732e80970951aa73a6f03e1988" target="_blank" rel="noopener">news.com.au</a> an investigation will be conducted reviewing video captured before and after the incident. “Australia Post’s Electric Delivery Vehicles (eDVs) are equipped with on-board telematics which capture video footage and data designed to help keep our people safe on the roads,” a spokesperson said.

<a href="https://theconversation.com/profiles/paul-haskell-dowland-382903">Paul Haskell-Dowland</a>, <a href="https://theconversation.com/institutions/edith-cowan-university-720">Edith Cowan University</a> and <a href="https://theconversation.com/profiles/ismini-vasileiou-1031778">Ismini Vasileiou</a>, <a href="https://theconversation.com/institutions/de-montfort-university-1254">De Montfort University</a> Paying for things digitally is so common, most of us think nothing of swiping or tapping our card, or using mobile payments. While doing so is second nature, we may be more reluctant to provide card details over the phone. Merchants are allowed to ask us for credit card details over the phone – this is perfectly legal. But there are minimum standards they must comply with and safeguards to protect consumer data. So is giving your card details over the phone any more risky than other transactions and how can you minimise the risks? <h2>How is my card data protected?</h2> For a merchant to process card transactions, they are expected to comply with the <a href="https://docs-prv.pcisecuritystandards.org/PCI%20DSS/Standard/PCI-DSS-v4_0.pdf">Payment Card Industry Data Security Standard</a>. This is a set of security requirements designed to protect cardholder data and the trillions of dollars of transactions each year. Compliance involves various security measures (such as encryption and access controls) together with strong governance and regular security assessments. If the information stored by the merchant is accessed by an unauthorised party, encryption ensures it is not readable. That means stealing the data would not let the criminals use the card details. Meanwhile, access controls ensure only authorised individuals have access to cardholder data. Though all companies processing cards are expected to meet the compliance standards, only those processing large volumes are subject to mandatory regular audits. Should a subsequent data leak or misuse occur that can be attributed to a compliance failure, a <a href="https://www.csoonline.com/article/569591/pci-dss-explained-requirements-fines-and-steps-to-compliance.html">company can be penalised</a> at levels that can escalate into millions of dollars. These requirements apply to all card transactions, whether in person, online or over the phone. Phone transactions are likely to involve a human collecting the card details and either entering them into computer systems, or processing the payment through paper forms. The payment card Security Standards Council has <a href="https://docs-prv.pcisecuritystandards.org/Guidance%20Document/Telephone-Based%20Payments/Protecting_Telephone_Based_Payment_Card_Data_v3-0_nov_2018.pdf">detailed guides for best practice</a>: <blockquote> A policy should be in place to ensure that payment card data is protected against unauthorised viewing, copying, or scanning, in particular on desks. </blockquote> Although these measures can help to protect your card data, there are still risks in case the details are misplaced or the person on the phone aren’t who they say they are. <h2>Basic tips for safe credit card use over the phone</h2> If you provide card details over the phone, there are steps you can take to minimise the chance you’ll become the victim of fraud, or get your details leaked. 1. Verify the caller If you didn’t initiate the call, hang up and call the company directly using details you’ve verified yourself. Scammers will often masquerade as a well-known company (for example, an online retailer or a courier) and convince you a payment failed or payment is needed to release a delivery. Before you provide any information, confirm the caller is legitimate and the purpose of the call is genuine. 2. Be sceptical If you are being offered a deal that’s too good to be true, have concerns about the person you’re dealing with, or just feel something is not quite right, hang up. You can always call them back later if the caller turns out to be legitimate. 3. Use secure payment methods If you’ve previously paid the company with other (more secure) methods, ask to use that same method. 4. Keep records Make sure you record details of the company, the representative you are speaking to and the amount being charged. You should also ask for an order or transaction reference. Don’t forget to ask for the receipt to be sent to you. Check the transaction against your card matches the receipt – use your banking app, don’t wait for the statement to come through. <h2>Virtual credit cards</h2> In addition to the safeguards mentioned above, a <a href="https://www.forbes.com/advisor/credit-cards/virtual-credit-card-numbers-guide/">virtual credit card</a> can help reduce the risk of card fraud. You probably already have a form of virtual card if you’ve added a credit card to your phone for mobile payments. Depending on the financial institution, you can create a new credit card number linked to your physical card. Some banks extend this functionality to allow you to generate unique card numbers and/or CVV numbers (the three digits at the back of your card). With this approach you can easily separate transactions and cancel a virtual card/number if you have any concerns. <h2>What to do if you think your card details have been compromised or stolen?</h2> It’s important not to panic, but quick action is essential: <ul> <li> call your bank and get the card blocked so you won’t lose any more money. Depending on your situation, you can also block/cancel the card through your banking app or website </li> <li> report the issue to the police or other relevant body </li> <li> monitor your account(s) for any unusual transactions </li> <li> explore card settings in your banking app or website – many providers allow you to limit transactions based on value, restrict transaction types or enable alerts </li> <li> you may want to consider registering for <a href="https://theconversation.com/your-credit-report-is-a-key-part-of-your-privacy-heres-how-to-find-and-check-it-116999">credit monitoring services</a> and to enable fraud alerts. </li> </ul> <h2>So, should I give my card details over the phone?</h2> If you want to minimise risk, it’s best to avoid giving card details over the phone if you can. Providing your card details via a website still has risks, but at least it removes the human element. The best solution currently available is to use virtual cards – if anything goes wrong you can cancel just that unique card identity, rather than your entire card.<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/216833/count.gif?distributor=republish-lightbox-basic" alt="The Conversation" width="1" height="1" /> <a href="https://theconversation.com/profiles/paul-haskell-dowland-382903">Paul Haskell-Dowland</a>, Professor of Cyber Security Practice, <a href="https://theconversation.com/institutions/edith-cowan-university-720">Edith Cowan University</a> and <a href="https://theconversation.com/profiles/ismini-vasileiou-1031778">Ismini Vasileiou</a>, Associate Professor, <a href="https://theconversation.com/institutions/de-montfort-university-1254">De Montfort University</a> Image credits: Getty Images This article is republished from <a style="font-style: italic;" href="https://theconversation.com">The Conversation</a> under a Creative Commons license.

"32 years of safe landings": Pilot's surprise speech reduces passengers to tears

A pilot has brought his passengers to tears with an emotional speech on his final flight after 32 years in the skies. Jeff Fell, an American Airlines pilot, took off from Chicago on his retirement flight as he stood in front of his passengers and delivered a heartfelt message. At first, his message seemed routine, informing travellers of the weather and and flight time, before acknowledging it was strange for him to deliver the address from outside the cockpit. “I normally don’t stand up in front of everybody like this, I usually just stay in the cockpit and talk on the PA. If I get a little emotional please forgive me for that,” he said in the speech, which was captured on video by a passenger. With passengers still unaware of what was to come, he pointed out a group of “very important people” to him sitting at the back of the plane. “They’re the majority of my family who have come along with me on my retirement flight,” Mr Fell said. The plane was filled with applause as the pilot's voice wavered with emotion. “They’re on-board with me on my retirement flight after 32 years with American,” he said. He continued, fighting back tears, “Thank you all for coming along with me tonight and celebrating this very memorable time in my life. I love all of you." With another round of applause from his passengers, Mr Fell added:, “I didn’t want to get emotional but goodness gracious.” “Finally, for my wonderful wife Julie who has been at my side for the majority of my 32 years at American. She has been the rock, the solid rock in the foundation in our lives and our marriage. Her faith in the Lord, wisdom, strength and love has guided our marriage and family throughout these years. I love you and look forward to the next chapter in our lives. And welcome aboard everybody.” The video was uploaded to TikTok and has since gone viral, raking up millions of views, and you can watch the full video <a href="https://www.tiktok.com/@realjharrison/video/7299484162648509738" target="_blank" rel="noopener">here</a>. Thousands of social media users left comments of support, with many confessing the clip had brought them to tears. “As soon as he said retirement flight my tears came,” one person wrote, while another added, "32 years of safe landings also. God bless him and all pilots.” “To think of the amount of families, people, and cultures he has single-handedly connected throughout the world. Thank you!” penned a third person. “32 years of bringing people closer together. I’m crying!” agreed another. Image credits: TikTok

How do stimulants actually work to reduce ADHD symptoms?

<a href="https://theconversation.com/profiles/mary-bushell-919262">Mary Bushell</a>, <a href="https://theconversation.com/institutions/university-of-canberra-865">University of Canberra</a> Stimulants are <a href="https://adhdguideline.aadpa.com.au/">first-line drugs</a> for children and adults diagnosed with attention-deficit hyperactivity disorder (ADHD). But how do they actually work? <h2>First, let’s look at the brain</h2> ADHD is a neurodevelopmental condition, which means it affects how the brain functions. Medical imaging indicates people with ADHD may have slight differences in their brain’s <a href="https://jamanetwork.com/journals/jama/article-abstract/195386">structure</a>, the way their brain regions work together to perform tasks, and how their brain’s chemical messengers, called neurotransmitters, pass on information. These brain differences are associated with the symptoms of ADHD, including inattention, impulse control and problems with memory. <h2>What stimulants are prescribed in Australia?</h2> The three main stimulants prescribed for ADHD in Australia are dexamfetamine, methylphenidate (sold under the brand names Ritalin and Concerta) and lisdexamfetamine (sold as Vyvanse). Dexamfetamine and methylphenidate have been around <a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC3666194/">since</a> the 1930s and 1940s respectively. Lisdexamfetamine is a newer stimulant that has been around <a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC2873712/">since</a> the late 2000s. Dexamfetamine and lisdexamfetamine are amphetamines. <a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC2873712/">Lisdexamfetamine</a> is inactive when it’s taken and actually changes into active dexamfetamine in the red blood cells. This is what’s known as a “prodrug”. <h2>So how do they work for ADHD?</h2> Stimulant drugs are thought to alter the activity of key neuotransmitters, dopamine and noradrenaline, in the brain. These neurotransmitters help with attention and focus, among other things. Stimulants increase the amount of dopamine and noradrenaline in the tiny gaps between neurons, known as synapses. They do this by predominantly blocking a transporter that then prevents their re-uptake back into the neuron that released them. This means more dopamine and noradrenaline can bind to their respective receptors. This <a href="https://www.tga.gov.au/sites/default/files/auspar-lisdexamfetamine-dimesilate-180515-pi.pdf">helps</a> connected neurons in the brain talk to one another. Amphetamines also increase the amount of dopamine the neuron releases into the synapse (the tiny gaps between neurons). And it stops the enzymes that break down dopamine. This results in an increase of dopamine in the synapse. <h2>What effect do they have on ADHD symptoms?</h2> We still don’t fully understand the underlying brain mechanisms that change behaviour in people with ADHD. But <a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC6109107/">research shows</a> stimulants that modulate noradrenaline and dopamine can improve brain processes such as: <ul> <li>attention</li> <li>memory</li> <li>decision-making</li> <li>task completion</li> <li>hyperactivity.</li> </ul> They can also improve general behaviour, such as self-control, not talking over the top of others, and concentration. These behaviours are important for social interactions. Stimulants <a href="https://pubmed.ncbi.nlm.nih.gov/15737659/">reduce ADHD symptoms</a> in about 70% to 80% of children and adults who take them. Some people will notice their symptoms improve right away. Other times, these improvements will be more noticeable to parents, carers, teachers, colleagues and partners. <h2>Not everyone gets the same dose</h2> The optimal stimulant dose varies between individuals, with multiple dosage options available. This enables a “start low, go slow” approach, where the stimulant can be gradually increased to the most effective dose for the individual. There are also different delivery options. Dexamfetamine and methylphenidate are available in immediate-release preparations. As these have short half-lives (meaning they act quickly and wear off rapidly), they are often taken multiple times a day – usually in the morning, lunch and afternoon. Methylphenidate is also <a href="https://www.ebs.tga.gov.au/ebs/picmi/picmirepository.nsf/pdf?OpenAgent&id=CP-2010-PI-03175-3&d=20231023172310101">available</a> in long-acting tablets (Concerta) and capsules (Ritalin LA). They are released into the body over the day. Lisdexamfetamine is a long-acting drug and is not available in a short-acting formulation. The long-acting stimulants are generally taken once in the morning. This avoids the need to take tablets during school or work hours (and the need to store a “controlled drug”, which has the potential for abuse, outside the home). <h2>What are the side effects?</h2> The most common side effects are sleep problems and decreased appetite. A <a href="https://www.cochranelibrary.com/cdsr/doi/10.1002/14651858.CD012069.pub2/full">recent study</a> showed children and young people taking methylphenidate for ADHD were around 2.6 times more likely to have sleep problems and 15 times more likely to have a decreased appetite than those not taking methylphenidate. Headache and abdominal pain are also relatively common. <h2>Can someone without ADHD take a stimulant to improve productivity?</h2> Stimulants are tightly controlled because of their potential for abuse. In Australia, only paediatricians, psychiatrists or neurologists (and GPs in special circumstances) can prescribe them. This follows a long assessment process. As stimulants increase dopamine, they can cause euphoria and a heightened sense of wellbeing. They can also cause <a href="https://www.ncbi.nlm.nih.gov/books/NBK576548/#:%7E:text=The%20immediate%20psychological%20effects%20of,and%20may%20result%20in%20insomnia.">weight loss</a>. A common myth about stimulant medicines is they can improve the concentration and productivity of people without ADHD. A <a href="https://www.science.org/doi/full/10.1126/sciadv.add4165">recent study shows</a> the opposite is true. This study gave a group of 40 people online arithmetic tasks to complete across four sessions. At each of the sessions, participants were given either a placebo or a stimulant before completing the task. The results showed that while stimulants did not impact getting the correct answer, it increased the number of moves and time to solve the problems compared to a placebo. This indicates a reduction in productivity. However, the myth that stimulants improve study prevails. It’s likely that users feel different – after all, they are taking a medicine that speeds up messages between the brain and body. It may make them “feel” more alert and productive, even if they’re not.<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/215801/count.gif?distributor=republish-lightbox-basic" alt="The Conversation" width="1" height="1" /> <a href="https://theconversation.com/profiles/mary-bushell-919262">Mary Bushell</a>, Clinical Assistant Professor in Pharmacy, <a href="https://theconversation.com/institutions/university-of-canberra-865">University of Canberra</a> Image credits: Getty Images This article is republished from <a href="https://theconversation.com">The Conversation</a> under a Creative Commons license.

How 22 minutes of exercise a day could reduce the health risks from sitting too long

<a href="https://theconversation.com/profiles/matthew-ahmadi-1241767">Matthew Ahmadi</a>, <a href="https://theconversation.com/institutions/university-of-sydney-841">University of Sydney</a> and <a href="https://theconversation.com/profiles/emmanuel-stamatakis-161783">Emmanuel Stamatakis</a>, <a href="https://theconversation.com/institutions/university-of-sydney-841">University of Sydney</a> People in developed countries spend an average of <a href="https://doi.org/10.1136/bjsports-2022-106568">nine to ten hours</a> a day sitting. Whether it’s spending time in front of a computer, stuck in traffic, or unwinding in front of the TV, our lives have become increasingly sedentary. This is concerning because prolonged time spent sitting is <a href="https://bjsm.bmj.com/content/54/24/1451?s=09&int_source=trendmd&int_medium=cpc&int_campaign=usage-042019">linked to a number of health issues</a> including obesity, heart disease, and certain types of cancers. These health issues can contribute to earlier death. But a <a href="https://doi.org/10.1136/bjsports-2022-106568">new study</a> suggests that for people over 50, getting just 22 minutes of exercise a day can lower the increased risk of premature death from a highly sedentary lifestyle. <h2>What the researchers did</h2> The team combined data from two studies from Norway, one from Sweden and one from the United States. The studies included about 12,000 people aged 50 or older who wore wearable devices to track how active and sedentary they were during their daily routines. Participants were followed up for at least two years (the median was 5.2 years) during the study period, which spanned 2003-2020. Analyses took several lifestyle and health factors into account, such as education, alcohol intake, smoking status, and previous history of heart disease, cancer and diabetes. All this data was linked to national death registries. <h2>A 22 minute threshold</h2> A total of 805 participants died during follow up. The researchers found people who were sedentary for more than 12 hours a day had the highest risk of death (a 38% higher risk than people who were sedentary for eight hours). However, this was only observed in those who did less than 22 minutes of moderate to vigorous physical activity daily. So for people who did more than 22 minutes of exercise, there was no longer a significantly heightened risk – that is, the risk became generally similar to those who were sedentary for eight hours. Higher daily duration of physical activity was consistently associated with lower risk of death, regardless of total sedentary time. For example, the team reported an additional ten minutes of moderate to vigorous physical activity each day could lower mortality risk by up to 15% for people who were sedentary less than 10.5 hours a day. For those considered highly sedentary (10.5 hours a day or more), an additional ten minutes lowered mortality risk by up to 35%. <h2>The study had some limitations</h2> The team couldn’t assess how changes in physical activity or sedentary time over several months or years may affect risk of death. And the study included only participants aged 50 and above, making results less applicable to younger age groups. Further, cultural and lifestyle differences between countries may have influenced how data between studies was measured and analysed. Ultimately, because this study was observational, we can’t draw conclusions on cause and effect with certainty. But the results of this research align with a growing body of evidence exploring the relationship between physical activity, sedentary time, and death. <h2>It’s positive news</h2> Research has previously suggested <a href="https://bjsm.bmj.com/content/54/24/1499">physical activity may offset</a> health risks associated with <a href="https://www.jacc.org/doi/abs/10.1016/j.jacc.2019.02.031">high sedentary time</a>. The good news is, even short bouts of exercise can have these positive effects. In this study, the 22 minutes wasn’t necessarily done all at once. It was a total of the physical activity someone did in a day, and would have included incidental exercise (activity that’s part of a daily routine, such as climbing the stairs). Several studies using wearable devices have found short bursts of high-intensity everyday activities such as stair climbing or energetic outdoor home maintenance activities such as mowing the lawn or cleaning the windows can lower <a href="https://www.nature.com/articles/s41591-022-02100-x">mortality</a>, <a href="https://academic.oup.com/eurheartj/article/43/46/4801/6771381">heart disease</a> and <a href="https://jamanetwork.com/journals/jamaoncology/fullarticle/2807734">cancer</a> risk. A recent study using wearable devices found moderate to vigorous bouts of activity <a href="https://www.thelancet.com/journals/lanpub/article/PIIS2468-2667(23)00183-4/fulltext">lasting three to five minutes</a> provide similar benefits to bouts longer than ten minutes when it comes to stroke and heart attack risk. Several other studies have found <a href="https://jamanetwork.com/journals/jamainternalmedicine/fullarticle/2596007">being active just on the weekend</a> provides similar health benefits as <a href="https://jamanetwork.com/journals/jamainternalmedicine/fullarticle/2794038">being active throughout the week</a>. Research has also shown the benefits of <a href="https://jamanetwork.com/journals/jamaneurology/fullarticle/2795819">physical activity</a> and <a href="https://jamanetwork.com/journals/jama/article-abstract/2809418">reducing sedentary time</a> extend to cognitive health. Routines such as desk jobs can foster a sedentary lifestyle that may be difficult to shift. But mixing short bursts of activity into our day can make a significant difference towards improving our health and longevity. Whether it’s a brisk walk during lunch, taking the stairs, or even a short at-home workout, this study is yet another to suggest that every minute counts.<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/216259/count.gif?distributor=republish-lightbox-basic" alt="The Conversation" width="1" height="1" /> <a href="https://theconversation.com/profiles/matthew-ahmadi-1241767">Matthew Ahmadi</a>, Postdoctoral Research Fellow, Faculty of Medicine and Health, <a href="https://theconversation.com/institutions/university-of-sydney-841">University of Sydney</a> and <a href="https://theconversation.com/profiles/emmanuel-stamatakis-161783">Emmanuel Stamatakis</a>, Professor of Physical Activity, Lifestyle, and Population Health, <a href="https://theconversation.com/institutions/university-of-sydney-841">University of Sydney</a> Image credits: Getty Images This article is republished from <a href="https://theconversation.com">The Conversation</a> under a Creative Commons license.

Do blue-light glasses really work? Can they reduce eye strain or help me sleep?

<a href="https://theconversation.com/profiles/laura-downie-1469379">Laura Downie</a>, <a href="https://theconversation.com/institutions/the-university-of-melbourne-722">The University of Melbourne</a> Blue-light glasses are said to <a href="https://www.baxterblue.com.au/collections/blue-light-glasses">reduce eye strain</a> when using <a href="https://www.blockbluelight.com.au/collections/computer-glasses">computers</a>, improve your <a href="https://www.ocushield.com/products/anti-blue-light-glasses">sleep</a> and protect your eye health. You can buy them yourself or your optometrist can prescribe them. But <a href="https://mivision.com.au/2019/03/debate-continues-over-blue-blocking-lenses/">do they work</a>? Or could they do you harm? We <a href="https://www.cochranelibrary.com/cdsr/doi/10.1002/14651858.CD013244.pub2/full">reviewed</a> the evidence. Here’s what we found. <h2>What are they?</h2> Blue-light glasses, blue light-filtering lenses or blue-blocking lenses are different terms used to describe lenses that reduce the amount of short-wavelength visible (blue) light reaching the eyes. Most of these lenses prescribed by an optometrist decrease blue light transmission by <a href="https://onlinelibrary.wiley.com/doi/10.1111/opo.12615">10-25%</a>. Standard (clear) lenses do not filter blue light. A wide variety of lens products are available. A filter can be added to prescription or non-prescription lenses. They are widely marketed and are becoming <a href="https://onlinelibrary.wiley.com/doi/10.1111/opo.12615">increasingly popular</a>. There’s often an added cost, which depends on the specific product. So, is the extra expense worth it? <h2>Blue light is all around us</h2> Outdoors, sunlight is the main source of blue light. Indoors, light sources – such as light-emitting diodes (LEDs) and the screens of digital devices – emit varying degrees of blue light. The amount of blue light emitted from artificial light sources is much lower than from the Sun.

So we conducted a <a href="https://www.cochranelibrary.com/cdsr/doi/10.1002/14651858.CD013244.pub2/full">systematic review</a> to bring together and evaluate all the relevant studies. We included all randomised controlled trials (clinical studies designed to test the effects of interventions) that evaluated blue light-filtering lenses in adults. We identified 17 eligible trials from six countries, involving a total of 619 adults. <h2>Do they reduce eye strain?</h2> We found no benefit of using blue light-filtering lenses, over standard (clear) lenses, to reduce eye strain with computer use. This conclusion was based on consistent findings from three studies that evaluated effects on eye strain over time periods ranging from two hours to five days. <h2>Do they help you sleep?</h2> Possible effects on sleep were uncertain. Six studies evaluated whether wearing blue-light filtering lenses before bedtime could improve sleep quality, and the findings were mixed. These studies involved people with a diverse range of medical conditions, including insomnia and bipolar disorder. Healthy adults were not included in the studies. So we do not yet know whether these lenses affect sleep quality in the general population. <h2>Do they boost your eye health?</h2> We did not find any clinical evidence to support using blue-light filtering lenses to protect the macula (the region of the retina that controls high-detailed, central vision). None of the studies evaluated this. <h2>Could they do harm? How about causing headaches?</h2> We could not draw clear conclusions on whether there might be harms from wearing blue light-filtering lenses, compared with standard (non blue-light filtering) lenses. Some studies described how study participants had headaches, lowered mood and discomfort from wearing the glasses. However, people using glasses with standard lenses reported similar effects. <h2>What about other benefits or harms?</h2> There are some important general considerations when interpreting our findings. First, most of the studies were for a relatively short period of time, which limited our ability to consider longer-term effects on vision, sleep quality and eye health. Second, the review evaluated effects in adults. We don’t yet know if the effects are different for children. Finally, we could not draw conclusions about the possible effects of blue light-filtering lenses on many vision and eye health measures, including colour vision, as the studies did not evaluate these. <h2>In a nutshell</h2> Overall, based on relatively limited published clinical data, our review does not support using blue-light filtering lenses to reduce eye strain with digital device use. It is unclear whether these lenses affect vision quality or sleep, and no conclusions can be drawn about any potential effects on the health of the retina. High-quality research is needed to answer these questions, as well as whether the effectiveness and safety of these lenses varies in people of different ages and health status. If you have eye strain, or other eye or vision concerns, discuss this with your optometrist. They can perform a thorough examination of your eye health and vision, and discuss any relevant treatment options.<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/213145/count.gif?distributor=republish-lightbox-basic" alt="The Conversation" width="1" height="1" /> <a href="https://theconversation.com/profiles/laura-downie-1469379">Laura Downie</a>, Associate Professor in Optometry and Vision Sciences, <a href="https://theconversation.com/institutions/the-university-of-melbourne-722">The University of Melbourne</a> Image credits: Getty Images This article is republished from <a href="https://theconversation.com">The Conversation</a> under a Creative Commons license.

What is cognitive functional therapy? How can it reduce low back pain and get you moving?

<a href="https://theconversation.com/profiles/peter-osullivan-48973">Peter O'Sullivan</a>, <a href="https://theconversation.com/institutions/curtin-university-873">Curtin University</a>; <a href="https://theconversation.com/profiles/jp-caneiro-1463060">JP Caneiro</a>, <a href="https://theconversation.com/institutions/curtin-university-873">Curtin University</a>; <a href="https://theconversation.com/profiles/mark-hancock-1463059">Mark Hancock</a>, <a href="https://theconversation.com/institutions/macquarie-university-1174">Macquarie University</a>, and <a href="https://theconversation.com/profiles/peter-kent-1433302">Peter Kent</a>, <a href="https://theconversation.com/institutions/curtin-university-873">Curtin University</a> If you haven’t had lower back pain, it’s likely you know someone who has. It affects <a href="https://pubmed.ncbi.nlm.nih.gov/22231424/">around 40% of adults</a> in any year, ranging from adolescents to those in later life. While most people recover, <a href="https://pubmed.ncbi.nlm.nih.gov/29112007/">around 20%</a> go on to develop chronic low back pain (lasting more than three months). There is a <a href="https://bjsm.bmj.com/content/54/12/698">common view</a> that chronic low back pain is caused by permanent tissue damage including “wear and tear”, disc degeneration, disc bulges and arthritis of the spine. This “damage” is often described as resulting from injury and loading of the spine (such as bending and lifting), ageing, poor posture and weak “core” muscles. We’re often told to “protect” our back by sitting tall, bracing the core, keeping a straight back when bending and lifting, and avoiding movement and activities that are painful. Health practitioners often <a href="https://theconversation.com/having-good-posture-doesnt-prevent-back-pain-and-bad-posture-doesnt-cause-it-183732">promote and reinforce these messages</a>. But this is <a href="https://bjsm.bmj.com/content/54/12/698">not based on evidence</a>. An emerging treatment known as <a href="https://pubmed.ncbi.nlm.nih.gov/29669082/">cognitive functional therapy</a> aims to help patients undo some of these unhelpful and restrictive practices, and learn to trust and move their body again. <h2>People are often given the wrong advice</h2> People with chronic back pain are often referred for imaging scans to detect things like disc degeneration, disc bulges and arthritis. But these findings are very common in people without low back pain and research shows they <a href="https://pubmed.ncbi.nlm.nih.gov/24276945/">don’t accurately predict</a> a person’s current or future experience of pain. Once serious causes of back pain have been ruled out (such as cancer, infection, fracture and nerve compression), there is <a href="https://pubmed.ncbi.nlm.nih.gov/27745712/">little evidence</a> scan findings help guide or improve the care for people with chronic low back pain. In fact, scanning people and telling them they have arthritis and disc degeneration can <a href="https://pubmed.ncbi.nlm.nih.gov/33748882/">frighten them</a>, resulting in them avoiding activity, worsening their pain and distress. It can also lead to potentially harmful treatments such as <a href="https://pubmed.ncbi.nlm.nih.gov/27213267/">opioid</a> pain medications, and invasive treatments such as spine <a href="https://pubmed.ncbi.nlm.nih.gov/19127161/">injections</a>, spine <a href="https://pubmed.ncbi.nlm.nih.gov/12709856/">surgery</a> and battery-powered electrical stimulation of spinal nerves. <h2>So how should low back pain be treated?</h2> A complex range of factors <a href="https://pubmed.ncbi.nlm.nih.gov/29112007/">typically contribute</a> to a person developing chronic low back pain. This includes over-protecting the back by avoiding movement and activity, the belief that pain is related to damage, and negative emotions such as pain-related fear and anxiety. Addressing these factors in an individualised way is <a href="https://pubmed.ncbi.nlm.nih.gov/29573871/">now considered</a> best practice. <a href="https://pubmed.ncbi.nlm.nih.gov/15936976/">Best practice care</a> also needs to be person-centred. People suffering from chronic low back pain want to be heard and validated. They <a href="https://pubmed.ncbi.nlm.nih.gov/35384928/">want</a> to understand why they have pain in simple language. They want care that considers their preferences and gives a safe and affordable pathway to pain relief, restoring function and getting back to their usual physical, social and work-related activities. An example of this type of care is cognitive functional therapy. <h2>What is cognitive functional therapy?</h2> <a href="https://pubmed.ncbi.nlm.nih.gov/29669082/">Cognitive functional therapy</a> is about putting the person in the drivers’ seat of their back care, while the clinician takes the time to guide them to develop the skills needed to do this. It’s led by physiotherapists and can be used once serious causes of back pain have been ruled out. The therapy helps the person understand the unique contributing factors related to their condition, and that pain is usually not an accurate sign of damage. It guides patients to relearn how to move and build confidence in their back, without over-protecting it. It also addresses other factors such as sleep, relaxation, work restrictions and engaging in physical activity based on the <a href="https://www.restorebackpain.com/patient-journey">person’s preferences</a>. Cognitive functional therapy usually involves longer physiotherapy sessions than usual (60 minutes initially and 30-45 minute follow-ups) with up to seven to eight sessions over three months and booster sessions when required. <h2>What’s the evidence for this type of therapy?</h2> Our recent clinical trial of cognitive functional therapy, published in <a href="https://www.thelancet.com/journals/lancet/article/PIIS0140-6736(23)00441-5/fulltext">The Lancet</a>, included 492 people with chronic low back pain. The participants had pain for an average of four years and had tried many other treatments. We first trained 18 physiotherapists to competently deliver cognitive functional therapy across Perth and Sydney over six months. We compared the therapy to the patient’s “usual care”. We found large and sustained improvements in function and reductions in pain intensity levels for people who underwent the therapy, compared with those receiving usual care. The effects remained at 12 months, which is unusual in low back pain trials. The effects of most recommended interventions such as exercise or psychological therapies are <a href="https://pubmed.ncbi.nlm.nih.gov/34580864/">modest in size</a> and tend to be of <a href="https://pubmed.ncbi.nlm.nih.gov/32794606/">short duration</a>. People who underwent cognitive functional therapy were also more confident, less fearful and had a more positive mindset about their back pain at 12 months. They also liked it, with 80% of participants satisfied or highly satisfied with the treatment, compared with 19% in the usual care group. The treatment was as safe as usual care and was also cost-effective. It saved more than A$5,000 per person over a year, largely due to increased participation at work. <h2>What does this mean for you?</h2> This trial shows there are safe, relatively cheap and effective treatments options for people living with chronic pain, even if you’ve tried other treatments without success. <a href="https://www.restorebackpain.com/cft-clinicians">Access to clinicians</a> trained in cognitive functional therapy is currently limited but will expand as training is scaled up. The costs depend on how many sessions you have. Our studies show some people improve a lot within two to three sessions, but most people had seven to eight sessions, which would cost around A$1,000 (aside from any Medicare or private health insurance rebates). <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/207009/count.gif?distributor=republish-lightbox-basic" alt="The Conversation" width="1" height="1" /> <a href="https://theconversation.com/profiles/peter-osullivan-48973">Peter O'Sullivan</a>, Professor of Musculoskeletal Physiotherapy, <a href="https://theconversation.com/institutions/curtin-university-873">Curtin University</a>; <a href="https://theconversation.com/profiles/jp-caneiro-1463060">JP Caneiro</a>, Research Fellow in physiotherapy, <a href="https://theconversation.com/institutions/curtin-university-873">Curtin University</a>; <a href="https://theconversation.com/profiles/mark-hancock-1463059">Mark Hancock</a>, Professor of Physiotherapy, <a href="https://theconversation.com/institutions/macquarie-university-1174">Macquarie University</a>, and <a href="https://theconversation.com/profiles/peter-kent-1433302">Peter Kent</a>, Adjunct Associate Professor of Physiotherapy, <a href="https://theconversation.com/institutions/curtin-university-873">Curtin University</a> Image credits: Shutterstock This article is republished from <a href="https://theconversation.com">The Conversation</a> under a Creative Commons license.
