New study suggests weight loss drugs like Ozempic could help with knee pain. Here’s why there may be a link

<p><em><a href="https://theconversation.com/profiles/giovanni-e-ferreira-1030477">Giovanni E.

Clinical trials show semaglutide can be effective for <a href="https://www.nejm.org/doi/full/10.1056/NEJMoa2032183">weight loss</a>, and hundreds of thousands of people around the world are using it <a href="https://theconversation.com/considering-taking-a-weight-loss-drug-like-ozempic-here-are-some-potential-risks-and-benefits-219312">for this purpose</a>.</p> <p>Evidence has also shown the drug can help manage <a href="https://www.nejm.org/doi/full/10.1056/NEJMoa2306963">heart failure</a> and <a href="https://www.nejm.org/doi/full/10.1056/NEJMoa2403347">chronic kidney disease</a> in people with obesity and type 2 diabetes.</p> <p>Now, a study published in the <a href="https://www.nejm.org/doi/full/10.1056/NEJMoa2403664">New England Journal of Medicine</a> has suggested semaglutide can improve knee pain in people with obesity and osteoarthritis. So what did this study find, and how could semaglutide and osteoarthritis pain be linked?</p> <h2>Osteoarthritis and obesity</h2> <p>Osteoarthritis is a common joint disease, affecting <a href="https://www.aihw.gov.au/reports/chronic-musculoskeletal-conditions/osteoarthritis">2.1 million Australians</a>. Most people with osteoarthritis <a href="https://theconversation.com/do-you-have-knee-pain-from-osteoarthritis-you-might-not-need-surgery-heres-what-to-try-instead-236779">have pain</a> and find it difficult to perform common daily activities such as walking. The knee is <a href="https://pubmed.ncbi.nlm.nih.gov/37675071/">the joint most commonly affected</a> by osteoarthritis.</p> <p>Being overweight or obese is a <a href="https://pubmed.ncbi.nlm.nih.gov/25447976/">major risk factor</a> for osteoarthritis in the knee. The link between the two conditions <a href="https://pubmed.ncbi.nlm.nih.gov/26821091/">is complex</a>. It involves a combination of increased load on the knee, <a href="https://www.nature.com/articles/s41413-023-00301-9">metabolic factors</a> such as high cholesterol and high blood sugar, and inflammation.</p> <p>For example, elevated blood sugar levels increase the production of inflammatory molecules in the body, which can damage the cartilage in the knee, and lead to the <a href="https://pubmed.ncbi.nlm.nih.gov/30712918/">development of osteoarthritis</a>.</p> <p>Weight loss is strongly recommended to reduce the pain of knee osteoarthritis in people who are overweight or obese. <a href="https://pubmed.ncbi.nlm.nih.gov/31908149/">International</a> and <a href="https://www.safetyandquality.gov.au/sites/default/files/2024-08/osteoarthritis-knee-clinical-care-standard-2024.pdf">Australian guidelines</a> suggest losing as little as 5% of body weight can help.</p> <p>But losing weight with just diet and exercise can be difficult for many people. <a href="https://pubmed.ncbi.nlm.nih.gov/26180980/">One study</a> from the United Kingdom found the annual probability of people with obesity losing 5% or more of their body weight was less than one in ten.</p> <p>Semaglutide has recently entered the market as a potential alternative route to weight loss. It comes from a class of drugs known as GLP-1 receptor agonists and works by increasing a person’s sense of fullness.</p> <h2>Semaglutide for osteoarthritis?</h2> <p>The rationale for the <a href="https://www.nejm.org/doi/full/10.1056/NEJMoa2403664">recent study</a> was that while we know weight loss alleviates symptoms of knee osteoarthritis, the effect of GLP-1 receptor agonists was yet to be explored. So the researchers set out to understand what effect semaglutide might have on knee osteoarthritis pain, alongside body weight.</p> <p>They randomly allocated 407 people with obesity and moderate osteoarthritis into one of two groups. One group received semaglutide once a week, while the other group received a placebo. Both groups were treated for 68 weeks and received counselling on diet and physical activity. At the end of the treatment phase, researchers measured changes in knee pain, function, and body weight.</p> <p>As expected, those taking semaglutide lost more weight than those in the placebo group. People on semaglutide lost around 13% of their body weight on average, while those taking the placebo lost around 3% on average. More than 70% of people in the semaglutide group lost at least 10% of their body weight compared to just over 9% of people in the placebo group.</p> <p>The study found semaglutide reduced knee pain significantly more than the placebo. Participants who took semaglutide reported an additional 14-point reduction in pain on a 0–100 scale compared to the placebo group.</p> <p>This is much greater than the pain reduction in another <a href="https://pubmed.ncbi.nlm.nih.gov/36511925/">recent study</a> among people with obesity and knee osteoarthritis. This study investigated the effects of a diet and exercise program compared to an attention control (where participants are provided with information about nutrition and physical activity). The results here saw only a 3-point difference between the intervention group and the control group on the same scale.</p> <p>The amount of pain relief reported in the semaglutide trial is also larger than that reported with commonly used pain medicines such as <a href="https://pubmed.ncbi.nlm.nih.gov/35442752/">anti-inflammatories</a>, <a href="https://pubmed.ncbi.nlm.nih.gov/35137418/">opioids</a> and <a href="https://www.bmj.com/content/372/bmj.m4825">antidepressants</a>.</p> <p>Semaglutide also improved knee function compared to the placebo. For example, people who took semaglutide could walk about 42 meters further than those on the placebo in a six-minute walking test.</p> <h2>How could semaglutide reduce knee pain?</h2> <p>It’s not fully clear how semaglutide helps with knee pain from osteoarthritis. One explanation may be that when a person loses weight, there’s less stress on the joints, which reduces pain.</p> <p>But recent studies have also suggested semaglutide and other GLP-1 receptor agonists might have <a href="https://www.sciencedirect.com/science/article/pii/S1043661822002651">anti-inflammatory</a> properties, and could even protect against <a href="https://pmc.ncbi.nlm.nih.gov/articles/PMC6731440/">cartilage wear and tear</a>.</p> <p>While the results of this new study are promising, it’s too soon to regard semaglutide as a “miracle drug” for knee osteoarthritis. And as this study was funded by the drug company that makes semaglutide, it will be important to have independent studies in the future, to confirm the findings, or not.</p> <p>The study also had strict criteria, excluding some groups, such as those taking opioids for knee pain. One in seven Australians seeing a GP for their knee osteoarthritis <a href="https://pubmed.ncbi.nlm.nih.gov/34527976/">are prescribed opioids</a>. Most participants in the trial were white (61%) and women (82%). This means the study may not fully represent the average person with knee osteoarthritis and obesity.</p> <p>It’s also important to consider semaglutide can have a range of <a href="https://theconversation.com/considering-taking-a-weight-loss-drug-like-ozempic-here-are-some-potential-risks-and-benefits-219312">side effects</a>, including gastrointestinal symptoms and fatigue.</p> <p>There are some concerns that semaglutide could reduce <a href="https://www.sciencealert.com/experts-are-concerned-drugs-like-ozempic-may-cause-muscle-loss">muscle mass</a> and <a href="https://www.healthline.com/health-news/ozempic-muscle-mass-loss">bone density</a>, though we’re still learning more about this.</p> <p>Further, it can be difficult to access.</p> <h2>I have knee osteoarthritis, what should I do?</h2> <p>Osteoarthritis is a disease caused by multiple factors, and it’s important to take <a href="https://www.safetyandquality.gov.au/standards/clinical-care-standards/osteoarthritis-knee-clinical-care-standard/information-consumers-osteoarthritis-knee-clinical-care-standard">a multifaceted approach</a> to managing it. Weight loss is an important component for those who are overweight or obese, but so are other aspects of <a href="https://theconversation.com/do-you-have-knee-pain-from-osteoarthritis-you-might-not-need-surgery-heres-what-to-try-instead-236779">self-management</a>.

Having the ‘right’ friends may hold the secret to building wealth, according to new study on socioeconomic ties

<p><em><a href="https://theconversation.com/profiles/brad-cannon-2216202">Brad Cannon</a>, <a href="https://theconversation.com/institutions/binghamton-university-state-university-of-new-york-2252">Binghamton University, State University of New York</a></em></p> <p>Having wealthy people in your social network significantly boosts the likelihood that you’ll participate in stock markets and savings plans, according to a new working paper I co-authored.</p> <p>My colleagues and I <a href="https://www.nber.org/system/files/working_papers/w32186/w32186.pdf">recently conducted research</a> on social finance to understand the ways in which social networks affect stock market participation and savings behavior. This is important because a substantial fraction of households in the U.S., particularly <a href="https://www.axios.com/2023/10/18/percentage-americans-own-stock-market-investing">lower-income families, do not own stocks</a>.</p> <p>Given that the total return to the U.S. stock market from 1980 through September 2024 has been over 12,000% – for example, US$1,000 <a href="https://ofdollarsanddata.com/sp500-calculator/">invested in the S&amp;P 500</a> in 1980 would be worth $121,350 today – this creates a disparity in wealth for those who participate relative to those who do not. Understanding why some people invest and others don’t is important for addressing social concerns such as rising inequality.</p> <p>In our study, we looked at <a href="https://academic.oup.com/ej/advance-article/doi/10.1093/ej/ueae074/7720537">social capital</a>, which is a measure of the value that comes from being in a group or having dense social networks. Researchers have found that social capital can have positive impacts on individuals and communities, spurring innovation, <a href="https://www.nature.com/articles/s41586-022-04996-4">economic prosperity</a> and better health outcomes. We used friendship data from Facebook to measure different aspects of social networks by county in the U.S. We combined this data with tax information from the Internal Revenue Service about investments and savings.</p> <p>We found that in counties where friendships with prosperous individuals are more common, investment and savings tend to be higher. Moreover, we found that having these friendships with wealthy individuals plays a more important role in shaping financial behaviors than two other aspects of social capital we looked at in our study: having a tight group of friends and living in a community with strong civic engagement.</p> <p>Of course, making wealthy friends alone does not guarantee you’ll invest or save more. But perhaps knowing people who invest makes it less daunting and fraught, particularly if those friends can serve as a resource and sounding board.</p> <p><em>“Friends with Benefits: Social Capital and Household Financial Behavior” was co-authored by <a href="https://www.marshall.usc.edu/personnel/david-hirshleifer">David Hirshleifer</a> and <a href="https://hankamer.baylor.edu/person/joshua-thornton">Joshua Thornton</a>.</em><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/239370/count.gif?distributor=republish-lightbox-basic" alt="The Conversation" width="1" height="1" /></p> <p><em><a href="https://theconversation.com/profiles/brad-cannon-2216202">Brad Cannon</a>, Assistant Professor of Finance, <a href="https://theconversation.com/institutions/binghamton-university-state-university-of-new-york-2252">Binghamton University, State University of New York</a></em></p> <p><em>Image credits: Shutterstock</em></p> <p><em>This article is republished from <a href="https://theconversation.com">The Conversation</a> under a Creative Commons license.

Breakthrough study finds genetic link to Parkinson's and ADHD

<p>A major scientific study has found a surprising link between the genes that control brain size and the risk of brain-related conditions. </p> <p>A Queensland Institute of Medical Research Associate Professor Miguel Renteria led an international team of experts who scanned DNA data and MRI scans from 76,000 participants.</p> <p>“Genetic variants associated with larger brain volumes in key brain regions also increase the risk of Parkinson’s disease, while variants linked to smaller brain volumes in key regions are associated with an increased risk of ADHD,” Renteria said. </p> <p>“It brings us closer to answering key questions about how genetics influence brain structure, and how we can potentially treat these conditions in future.”</p> <p>Parkinson’s Australia CEO Olivia Nassaris has celebrated the results of the study, saying the surprising results open the door to future treatment options for Parkinson’s, which currently has no cure or cause.</p> <p>“The more answers we have the closer we are to understanding this condition,” she said.</p> <p>Michael Wiseman, who has been living with Parkinson’s for eight years, said he is pleased more research is being done about the neurodegenerative condition.</p> <p>“I know it’s not going to benefit me in any way, as far as a cure or anything … I just hope they keep going, kicking some goals and finding results because it’s an insidious sort of thing, it’s a passenger I’ll have until I go to the grave.”</p> <p><em>Image credits: Shutterstock </em></p>

New study finds epilepsy drug could reduce sleep apnoea symptoms

<p>New research has found that a drug used for epilepsy could be used to reduce the symptoms of sleep apnoea. </p> <p>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. </p> <p>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. </p> <p>This provides an additional option for those unable to use mechanical breathing aids like the Cpap machines. </p> <p>“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. </p> <p>Researchers conducted a randomised controlled trial of almost 300 obstructive sleep apnoea patients across Europe, who did not use Cpap machines. </p> <p>They were divided into four groups and given either a placebo or different strengths of sulthiame. </p> <p>The study measured patients’ breathing, oxygen levels, heart rhythm, eye movements, as well as brain and muscle activity while asleep. </p> <p>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. </p> <p>The findings, were presented at the European Respiratory Society Congress in Vienna, Austria. </p> <p>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.</p> <p>“This potential alternative to the current main treatment would make it easier for people to manage their condition,” she said. </p> <p><em>Image: Shutterstock</em></p> <p> </p>

Constipation increases your risk of a heart attack, new study finds – and not just on the toilet

<p><em><a href="https://theconversation.com/profiles/vincent-ho-141549">Vincent Ho</a>, <a href="https://theconversation.com/institutions/western-sydney-university-1092">Western Sydney University</a></em></p> <p>If you Google the terms “constipation” and “heart attack” it’s not long before the name Elvis Presley crops up. Elvis had a longstanding history of chronic constipation and <a href="https://www.pbs.org/newshour/health/elvis-addiction-was-the-perfect-prescription-for-an-early-death">it’s believed</a> he was straining very hard to poo, which then led to a fatal heart attack.</p> <p>We don’t know what really happened to the so-called King of Rock “n” Roll back in 1977. There were likely several contributing factors to his death, and this theory is one of many.</p> <p>But after this famous case researchers took a strong interest in the link between constipation and the risk of a heart attack.</p> <p>This includes a recent <a href="https://journals.physiology.org/doi/abs/10.1152/ajpheart.00519.2024">study</a> led by Australian researchers involving data from thousands of people.</p> <h2>Are constipation and heart attacks linked?</h2> <p>Large <a href="https://www.nature.com/articles/s41598-023-38068-y">population</a> <a href="https://pubmed.ncbi.nlm.nih.gov/32873621/">studies</a> show constipation is linked to an increased risk of heart attacks.</p> <p>For example, an <a href="https://www.nature.com/articles/s41598-023-38068-y">Australian study</a> involved more than 540,000 people over 60 in hospital for a range of conditions. It found constipated patients had a higher risk of high blood pressure, heart attacks and strokes compared to non-constipated patients of the same age.</p> <p>A <a href="https://pubmed.ncbi.nlm.nih.gov/32873621/">Danish study</a> of more than 900,000 people from hospitals and hospital outpatient clinics also found that people who were constipated had an increased risk of heart attacks and strokes.</p> <p>It was unclear, however, if this relationship between constipation and an increased risk of heart attacks and strokes would hold true for healthy people outside hospital.</p> <p>These Australian and Danish studies also did not factor in the effects of drugs used to treat high blood pressure (hypertension), which can make you constipated.</p> <h2>How about this new study?</h2> <p>The recent <a href="https://journals.physiology.org/doi/abs/10.1152/ajpheart.00519.2024">international study</a> led by Monash University researchers found a connection between constipation and an increased risk of heart attacks, strokes and heart failure in a general population.</p> <p>The researchers analysed data from the <a href="https://www.ukbiobank.ac.uk">UK Biobank</a>, a database of health-related information from about half a million people in the United Kingdom.</p> <p>The researchers identified more than 23,000 cases of constipation and accounted for the effect of drugs to treat high blood pressure, which can lead to constipation.</p> <p>People with constipation (identified through medical records or via a questionnaire) were twice as likely to have a heart attack, stroke or heart failure as those without constipation.</p> <p>The researchers found a strong link between high blood pressure and constipation. Individuals with hypertension who were also constipated had a 34% increased risk of a major heart event compared to those with just hypertension.</p> <p>The study only looked at the data from people of European ancestry. However, there is good reason to believe the link between constipation and heart attacks applies to other populations.</p> <p>A <a href="https://pubmed.ncbi.nlm.nih.gov/26812003/">Japanese study</a> looked at more than 45,000 men and women in the general population. It found people passing a bowel motion once every two to three days had a higher risk of dying from heart disease compared with ones who passed at least one bowel motion a day.</p> <h2>How might constipation cause a heart attack?</h2> <p>Chronic constipation can lead to straining when passing a stool. This can result in <a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC8030287/">laboured breathing</a> and can lead to a rise in blood pressure.</p> <p>In <a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC8030287/">one Japanese study</a> including ten elderly people, blood pressure was high just before passing a bowel motion and continued to rise during the bowel motion. This increase in blood pressure lasted for an hour afterwards, a pattern not seen in younger Japanese people.</p> <p><a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC8030287/">One theory</a> is that older people have stiffer blood vessels due to atherosclerosis (thickening or hardening of the arteries caused by a build-up of plaque) and other age-related changes. So their high blood pressure can persist for some time after straining. But the blood pressure of younger people returns quickly to normal as they have more elastic blood vessels.</p> <p>As blood pressure rises, the risk of heart disease increases. The risk of developing heart disease <a href="https://pubmed.ncbi.nlm.nih.gov/12493255/">doubles</a> when systolic blood pressure (the top number in your blood pressure reading) rises permanently by 20 mmHg (millimetres of mercury, a standard measure of blood pressure).</p> <p>The systolic blood pressure rise with straining in passing a stool has been <a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC8030287/">reported to be</a> as high as 70 mmHg. This rise is only temporary but with persistent straining in chronic constipation this could lead to an increased risk of heart attacks.</p> <p><a href="https://pubmed.ncbi.nlm.nih.gov/22256893/">Some people</a> with chronic constipation may have an impaired function of their vagus nerve, which controls various bodily functions, including digestion, heart rate and breathing.</p> <p>This impaired function can result in abnormalities of heart rate and over-activation of the flight-fight response. This can, in turn, lead to elevated blood pressure.</p> <p>Another intriguing avenue of <a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC6399019/">research</a> examines the imbalance in gut bacteria in people with <a href="https://pubmed.ncbi.nlm.nih.gov/3596341/">constipation</a>.</p> <p>This imbalance, known as dysbiosis, can result in microbes and other substances leaking through the gut barrier into the bloodstream and triggering an immune response. This, in turn, can lead to low-grade inflammation in the blood circulation and arteries becoming stiffer, increasing the risk of a heart attack.</p> <p>This latest study also explored genetic links between constipation and heart disease. The researchers found shared genetic factors that underlie both constipation and heart disease.</p> <h2>What can we do about this?</h2> <p>Constipation affects around <a href="https://pubmed.ncbi.nlm.nih.gov/36826591/">19% of the global population</a> aged 60 and older. So there is a substantial portion of the population at an increased risk of heart disease due to their bowel health.</p> <p>Managing chronic constipation through dietary changes (particularly increased dietary fibre), increased physical activity, ensuring adequate hydration and using medications, if necessary, are all important ways to help improve bowel function and reduce the risk of heart disease.<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/237209/count.gif?distributor=republish-lightbox-basic" alt="The Conversation" width="1" height="1" /></p> <p><a href="https://theconversation.com/profiles/vincent-ho-141549"><em>Vincent Ho</em></a><em>, Associate Professor and clinical academic gastroenterologist, <a href="https://theconversation.com/institutions/western-sydney-university-1092">Western Sydney University</a></em></p> <p><em>Image credits: Shutterstock </em></p> <p><em>This article is republished from <a href="https://theconversation.com">The Conversation</a> under a Creative Commons license.

New study links Ozempic and Wegovy to suicidal thoughts

<p>A new study has found a link between weight reduction drugs and reports of suicidal thoughts. </p> <p>Semaglutide, the drug sold under the brand names Ozempic and Wegovy, has been widely used for weight loss despite only being approved for the treatment of diabetes. </p> <p>An analysis of data on the adverse drug reactions database of the World Health Organisation found a disproportionate number of people reporting suicidal thoughts while using semaglutide. </p> <p>The research published in JAMA Network also found that the effect was "significant" compared to other diabetes medication, and that people with anxiety and depression were more likely to report suicidal thoughts when taking the drug. </p> <p>The researches have called for "urgent clarification" and larger studies around how semaglutide medications impact the brain. </p> <p>"The study raises key questions about whether additional precautions are needed when prescribing semaglutide," Trevor Steward, a neurobiology researcher from the University of Melbourne said. </p> <p>However, there are a few limitations with the study as there were a lack of information about the dosages, and did not adjust for things like alcohol and substance misuse and off-label use. </p> <p>While the study did not find a direct cause between suicidal thoughts and the use of semaglutide, it is important to raise concerns, especially for those who may want to use these drugs based on information they found on social media, and therefore do not fully understand the risks. </p> <p>The use of semaglutide for weight loss in Australia is considered 'off label', meaning that it has been prescribed for purposes outside of its approved use. </p> <p>The Therapeutic Goods Administration (TGA) believes that these prescriptions have been driving shortages, which they are trying to address and believe will last until 2025. </p> <p><em>Images: Shutterstock</em></p> <p> </p>

But they have never been directly compared with psychological therapies – until now.</p> <p>Amid a nation-wide <a href="https://www.health.gov.au/sites/default/files/2023-10/national-mental-health-workforce-strategy-2022-2032.pdf">shortage</a> of mental health professionals, our research points to a potential solution. As we found lifestyle counselling was as effective as psychological therapy, our findings suggest dietitians and exercise physiologists may one day play a role in managing depression.</p> <h2>What did our study measure?</h2> <p>During the prolonged COVID lockdowns, Victorians’ distress levels were <a href="https://onlinelibrary.wiley.com/doi/full/10.5694/mja2.50831">high and widespread</a>. Face-to-face mental health services were limited.</p> <p>Our trial targeted people living in Victoria with elevated distress, meaning at least mild depression but not necessarily a diagnosed mental disorder. Typical symptoms included feeling down, hopeless, irritable or tearful.</p> <p>We partnered with our <a href="https://www.barwonhealth.org.au/mhdas/">local mental health service</a> to recruit 182 adults and provided group-based sessions on Zoom. All participants took part in up to six sessions over eight weeks, facilitated by health professionals.</p> <p>Half were randomly assigned to participate in a program co-facilitated by an accredited practising dietitian and an exercise physiologist. That group – called the lifestyle program – developed nutrition and movement goals:</p> <ul> <li>eating a wide variety of foods</li> <li>choosing high-fibre plant foods</li> <li>including high quality fats</li> <li>limiting discretionary foods, such as those high in saturated fats and added sugars</li> <li>doing enjoyable physical activity.</li> </ul> <p>The second group took part in psychotherapy sessions convened by two psychologists. The psychotherapy program used cognitive behavioural therapy (CBT), the gold standard for treating depression in <a href="https://jamanetwork.com/journals/jamapsychiatry/article-abstract/2730724">groups and when delivered remotely</a>.</p> <p>In both groups, participants could continue existing treatments (such as taking antidepressant medication). We gave both groups <a href="https://link.springer.com/article/10.1186/s12888-022-03840-3">workbooks and hampers</a>. The lifestyle group received a food hamper, while the psychotherapy group received items such as a colouring book, stress ball and head massager.</p> <h2>Lifestyle therapies just as effective</h2> <p>We found similar results in each program.</p> <p>At the trial’s beginning we gave each participant a score based on their self-reported mental health. We measured them again at the end of the program.</p> <p>Over eight weeks, those scores showed symptoms of depression reduced for participants in the lifestyle program (42%) and the psychotherapy program (37%). That difference was not statistically or clinically meaningful so we could conclude both treatments were as good as each other.</p> <p>There were some differences between groups. People in the lifestyle program improved their diet, while those in the psychotherapy program felt they had increased their social support – meaning how connected they felt to other people – compared to at the start of the treatment.</p> <p>Participants in both programs increased their physical activity. While this was expected for those in the lifestyle program, it was less expected for those in the psychotherapy program. It may be because they knew they were enrolled in a research study about lifestyle and subconsciously changed their activity patterns, or it could be a positive by-product of doing psychotherapy.</p> <p>There was also not much difference in cost. The lifestyle program was slightly cheaper to deliver: A$482 per participant, versus $503 for psychotherapy. That’s because hourly rates differ between dietitians and exercise physiologists, and psychologists.</p> <h2>What does this mean for mental health workforce shortages?</h2> <p>Demand for mental health services is increasing in Australia, while at the same time the workforce <a href="https://www.health.gov.au/sites/default/files/2023-10/national-mental-health-workforce-strategy-2022-2032.pdf">faces worsening nation-wide shortages</a>.</p> <p>Psychologists, who provide <a href="https://www.aihw.gov.au/getmedia/6b19e493-0ebe-420f-a9a3-e48b26aace9f/aihw-aus-249-ib.pdf?v=20240628145747&amp;inline=true">about half</a> of all mental health services, can have long wait times. Our results suggest that, with the appropriate training and guidelines, allied health professionals who specialise in diet and exercise could help address this gap.</p> <p>Lifestyle therapies can be combined with psychology sessions for multi-disciplinary care. But diet and exercise therapies could prove particularly effective for those on waitlists to see a psychologists, who may be receiving no other professional support while they wait.</p> <p>Many dietitians and exercise physiologists already have advanced skills and expertise in motivating behaviour change. Most accredited practising dietitians are trained in managing <a href="https://link.springer.com/content/pdf/10.1007/978-3-030-67929-3_38-1.pdf">eating disorders</a> or <a href="https://www.nature.com/articles/s41572-020-0200-2">gastrointestinal conditions</a>, which commonly overlap with depression.</p> <p>There is also a cost argument. It is <a href="https://journals.sagepub.com/doi/full/10.1177/1355819616668202">overall cheaper</a> to train a dietitian ($153,039) than a psychologist ($189,063) – and it takes less time.</p> <h2>Potential barriers</h2> <p>Australians with chronic conditions (such as diabetes) can access subsidised dietitian and exercise physiologist appointments under various Medicare treatment plans. Those with eating disorders can also access subsidised dietitian appointments. But mental health care plans for people with depression do not support subsidised sessions with dietitians or exercise physiologists, despite <a href="https://dietitiansaustralia.org.au/sites/default/files/2024-04/Dietitians%20Australia%20Mental%20Health%20Evidence%20Brief%202024.pdf">peak bodies</a> urging them to do so.</p> <p>Increased training, upskilling and Medicare subsidies would be needed to support dietitians and exercise physiologists to be involved in treating mental health issues.</p> <p><a href="https://foodandmoodcentre.com.au/academy">Our training</a> and clinical <a href="https://www.tandfonline.com/doi/full/10.1080/15622975.2022.2112074">guidelines</a> are intended to help clinicians practising lifestyle-based mental health care within their scope of practice (activities a health care provider can undertake).</p> <h2>Future directions</h2> <p>Our trial took place during COVID lockdowns and examined people with at least mild symptoms of depression who did not necessarily have a mental disorder.

Leaked footage shows Olympic star's horrific animal abuse

<p>The extent of dressage star Charlotte Dujardin's "error of judgement" has been revealed, just hours after she made the snap decision to withdraw from the Olympics just days before its commencement. </p> <p>The British dressage star, who is a three-time gold medallist and the joint most-decorated British female Olympian, withdrew and accepted a provisional six-month ban when coming clean about her acts of <a href="https://oversixty.com.au/travel/travel-trouble/no-excuse-olympic-legend-quits-days-before-paris-games-commence" target="_blank" rel="noopener">animal abuse</a> in the lead up to the Paris Games. </p> <p>Just hours after announcing her withdrawal from the equestrian events, a disturbing video of a training session began to circulate, in which she is alleged to have beaten a horse with a long whip 24 times in one minute.</p> <p>The video, first released by <em>Good Morning Britain</em>, was taken four years ago and allegedly showed the 39-year-old mistreating a horse when trying to get the animal to slowly trot during a lesson with a young student. </p> <p>With the trainee rider mounted on the horse, Dujardin can allegedly be seen whipping the horse’s legs repeatedly.</p> <p>The video has outraged many, with hundreds of people taking to social media to voice their shock and horror at the acts. </p> <p>Leading British social commentator David Kurten wrote on X, “The cruel abuse of this horse by Charlotte Dujardin is horrific and a stain on our nation."</p> <p>“Two urgent questions need answers: Did she whip horses regularly? Are dozens or hundreds of other dressage horses regularly whipped and abused by other trainers?”</p> <p>Former editor of Horse and Hound Lucy Higginson also added, “It has profoundly shocked everybody in the equestrian world.”</p> <p>The video was sent anonymously to the International Federation for Equestrian Sports (FEI), who made the choice to suspend Dujardin just days before the Paris Olympics are set to begin. </p> <p>“The FEI has officially announced the provisional suspension of British Dressage athlete Charlotte Dujardin effective immediately from the date of notification, 23 July 2024,” it said in a statement.</p> <p>“This decision renders her ineligible to participate in the upcoming Paris 2024 Olympic Games or any other events under the jurisdiction of the FEI.”</p> <p>“According to the information received, the footage was allegedly taken several years ago during a training session conducted by Ms Dujardin at a private stable,” the organisation said.</p> <p>The governing body said Dujardin had confirmed she was depicted in the video and had acknowledged that her conduct was “inappropriate”.</p> <p>“Charlotte Dujardin requested to be provisionally suspended pending the outcome of the investigations and voluntarily withdrew from the Paris 2024 Olympic Games and also confirmed that she will not participate in any competitions pending the outcome of the FEI’s investigation,” it said.</p> <p>“The FEI condemns any conduct contrary to the welfare of horses and has robust rules in place to address such behaviour.”</p> <p>When announcing her withdrawal from the Games, Dujardin said she made an "error of judgement", saying there was "no excuse" for her behaviour. </p> <p>She wrote in a statement on Instagram, “What happened was completely out of character and does not reflect how I train my horses or coach my pupils, however there is no excuse. I am deeply ashamed and should have set a better example in that moment.”</p> <p><em>Image credits: Instagram / Good Morning Britain</em></p>

Walking can prevent low back pain, a new study shows

<p><em><a href="https://theconversation.com/profiles/tash-pocovi-1293184">Tash Pocovi</a>, <a href="https://theconversation.com/institutions/macquarie-university-1174">Macquarie University</a>; <a href="https://theconversation.com/profiles/christine-lin-346821">Christine Lin</a>, <a href="https://theconversation.com/institutions/university-of-sydney-841">University of Sydney</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>; <a href="https://theconversation.com/profiles/petra-graham-892602">Petra Graham</a>, <a href="https://theconversation.com/institutions/macquarie-university-1174">Macquarie University</a>, and <a href="https://theconversation.com/profiles/simon-french-713564">Simon French</a>, <a href="https://theconversation.com/institutions/macquarie-university-1174">Macquarie University</a></em></p> <p>Do you suffer from low back pain that recurs regularly? If you do, you’re not alone. Roughly <a href="https://pubmed.ncbi.nlm.nih.gov/31208917/">70% of people</a> who recover from an episode of low back pain will experience a new episode in the following year.</p> <p>The recurrent nature of low back pain is a major contributor to the <a href="https://www.thelancet.com/journals/lanrhe/article/PIIS2665-9913(23)00098-X/fulltext">enormous burden</a> low back pain places on individuals and the health-care system.</p> <p>In our new study, published today in <a href="https://www.thelancet.com/journals/lancet/article/PIIS0140-6736(24)00755-4/fulltext">The Lancet</a>, we found that a program combining walking and education can effectively reduce the recurrence of low back pain.</p> <h2>The WalkBack trial</h2> <p>We randomly assigned 701 adults who had recently recovered from an episode of low back pain to receive an individualised walking program and education (intervention), or to a no treatment group (control).</p> <p>Participants in the intervention group were guided by physiotherapists across six sessions, over a six-month period. In the first, third and fifth sessions, the physiotherapist helped each participant to develop a personalised and progressive walking program that was realistic and tailored to their specific needs and preferences.</p> <p>The remaining sessions were short check-ins (typically less than 15 minutes) to monitor progress and troubleshoot any potential barriers to engagement with the walking program. Due to the COVID pandemic, most participants received the entire intervention via telehealth, using video consultations and phone calls.</p> <p>The program was designed to be manageable, with a target of five walks per week of roughly 30 minutes daily by the end of the six-month program. Participants were also encouraged to continue walking independently after the program.</p> <p>Importantly, the walking program was combined with education provided by the physiotherapists during the six sessions. This education aimed to give people a better understanding of pain, reduce fear associated with exercise and movement, and give people the confidence to self-manage any minor recurrences if they occurred.</p> <p>People in the control group received no preventative treatment or education. This reflects what <a href="https://www.sciencedirect.com/science/article/abs/pii/S2468781222001308?via%3Dihub">typically occurs</a> after people recover from an episode of low back pain and are discharged from care.</p> <h2>What the results showed</h2> <p>We monitored the participants monthly from the time they were enrolled in the study, for up to three years, to collect information about any new recurrences of low back pain they may have experienced. We also asked participants to report on any costs related to their back pain, including time off work and the use of health-care services.</p> <p>The intervention reduced the risk of a recurrence of low back pain that limited daily activity by 28%, while the recurrence of low back pain leading participants to seek care from a health professional decreased by 43%.</p> <p>Participants who received the intervention had a longer average period before they had a recurrence, with a median of 208 days pain-free, compared to 112 days in the control group.</p> <p>Overall, we also found this intervention to be cost-effective. The biggest savings came from less work absenteeism and less health service use (such as physiotherapy and massage) among the intervention group.</p> <p>This trial, like all studies, had some limitations to consider. Although we tried to recruit a wide sample, we found that most participants were female, aged between 43 and 66, and were generally well educated. This may limit the extent to which we can generalise our findings.</p> <p>Also, in this trial, we used physiotherapists who were up-skilled in health coaching. So we don’t know whether the intervention would achieve the same impact if it were to be delivered by other clinicians.</p> <h2>Walking has multiple benefits</h2> <p>We’ve all heard the saying that “prevention is better than a cure” – and it’s true. But this approach has been largely neglected when it comes to low back pain. Almost all <a href="https://www.sciencedirect.com/science/article/pii/S0140673618304896?via%3Dihub">previous studies</a> have focused on treating episodes of pain, not preventing future back pain.</p> <p>A limited number of <a href="https://pubmed.ncbi.nlm.nih.gov/26752509/">small studies</a> have shown that exercise and education can help prevent low back pain. However, most of these studies focused on exercises that are not accessible to everyone due to factors such as high cost, complexity, and the need for supervision from health-care or fitness professionals.</p> <p>On the other hand, walking is a free, accessible way to exercise, including for people in rural and remote areas with limited access to health care.</p> <p>Walking also delivers many other <a href="https://www.vichealth.vic.gov.au/sites/default/files/VH_Benefits-of-Walking-Summary2020.pdf">health benefits</a>, including better heart health, improved mood and sleep quality, and reduced risk of several chronic diseases.</p> <p>While walking is not everyone’s favourite form of exercise, the intervention was well-received by most people in our study. Participants <a href="https://pubmed.ncbi.nlm.nih.gov/37271689/">reported</a> that the additional general health benefits contributed to their ongoing motivation to continue the walking program independently.</p> <h2>Why is walking helpful for low back pain?</h2> <p>We don’t know exactly why walking is effective for preventing back pain, but <a href="https://www.e-jer.org/journal/view.php?number=2013600295">possible reasons</a> could include the combination of gentle movements, loading and strengthening of the spinal structures and muscles. It also could be related to relaxation and stress relief, and the release of “feel-good” endorphins, which <a href="https://my.clevelandclinic.org/health/body/23040-endorphins">block pain signals</a> between your body and brain – essentially turning down the dial on pain.</p> <p>It’s possible that other accessible and low-cost forms of exercise, such as swimming, may also be effective in preventing back pain, but surprisingly, <a href="https://pubmed.ncbi.nlm.nih.gov/34783263/">no studies</a> have investigated this.</p> <p>Preventing low back pain is not easy. But these findings give us hope that we are getting closer to a solution, one step at a time.<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/231682/count.gif?distributor=republish-lightbox-basic" alt="The Conversation" width="1" height="1" /></p> <p><em><a href="https://theconversation.com/profiles/tash-pocovi-1293184">Tash Pocovi</a>, Postdoctoral research fellow, Department of Health Sciences, <a href="https://theconversation.com/institutions/macquarie-university-1174">Macquarie University</a>; <a href="https://theconversation.com/profiles/christine-lin-346821">Christine Lin</a>, Professor, Institute for Musculoskeletal Health, <a href="https://theconversation.com/institutions/university-of-sydney-841">University of Sydney</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>; <a href="https://theconversation.com/profiles/petra-graham-892602">Petra Graham</a>, Associate Professor, School of Mathematical and Physical Sciences, <a href="https://theconversation.com/institutions/macquarie-university-1174">Macquarie University</a>, and <a href="https://theconversation.com/profiles/simon-french-713564">Simon French</a>, Professor of Musculoskeletal Disorders, <a href="https://theconversation.com/institutions/macquarie-university-1174">Macquarie University</a></em></p> <p><em>Image credits: Shutterstock </em></p> <p><em>This article is republished from <a href="https://theconversation.com">The Conversation</a> under a Creative Commons license.

What the fox! Driver finds wild animal trapped in his car

<p>A motorist has shared the startling moment a fox got trapped in the front grill of his car, after he accidentally hit the wild animal while travelling at 80km/h. </p> <p>While driving down a country road in South Australia on Saturday night, the man behind the wheel said he was shocked when he felt something slam into the car. </p> <p>When he later checked the vehicle, he was astonished to find the angry fox trying to break free from behind the front grill of the car. </p> <p>“Y’all thought you had a bad day,” he can be heard saying while filming the animal furiously biting the front grill in an attempt to escape.</p> <p>In a series of videos posted to TikTok, the man documented the fox's attempts at escape, before informing his followers that he had enlisted the help of a local vet to help free the animal. </p> <p>“Took him to the vet, they sedated him and we got him out safely, the poor guy,” he said, adding he was glad — and impressed — the fox was alive after such a high-speed impact.</p> <p>Throughout his videos, many took to the comments to offer their advice to free the fox, as one person suggested "popping the lid", with the driver explaining that he did but “couldn’t even see him through the bonnet”.</p> <p>The saga has been viewed more than 400,000 times in the past 24 hours, with numerous people saying they were stunned the fox wasn’t seriously injured. “How does this even happen?” one person wondered.</p> <p>“What in the fox is going on here!” another joked, while others pondered how the man would explain the incident to his insurance company.</p> <p>“Insurance would never believe you if you didn’t have that video,” someone else added.</p> <p><em>Image credits: TikTok</em></p>

Answering this question requires us to consider some of the nicer aspects of our own nature.</p> <h2>When animals reflect us</h2> <p>Witnessing animals get along well together isn’t just cute, it can also make us feel like we have things in common with other species, and feel more connected with the other life on the planet. <a href="https://www.frontiersin.org/journals/psychology/articles/10.3389/fpsyg.2014.00976/full">Decades of research</a> reveals how feeling connected to nature fosters happiness in humans.</p> <figure><iframe src="https://www.youtube.com/embed/PrJi-P61aLY?wmode=transparent&amp;start=7" width="440" height="260" frameborder="0" allowfullscreen="allowfullscreen"></iframe></figure> <p>While the mechanisms behind inter-species bonding are not fully understood, <a href="https://www.frontiersin.org/articles/10.3389/fnbeh.2022.994504/full">one 2022 research review</a> suggests the mechanisms that operate in other animals’ brains during social interactions with their own are similar to those that operate in human brains.</p> <p>The researchers suggest that, due to the evolution of common brain mechanisms, animals engaged in social interaction may experience similar emotions to humans who engage with their own friends or loved ones.</p> <p>So while it’s very hard to know what this subjective social experience is like for other animals – after all, they can’t report it on a questionnaire – there’s no reason to think it isn’t similar to our own.</p> <figure><iframe src="https://www.youtube.com/embed/ZVMsdz7aZpk?wmode=transparent&amp;start=102" width="440" height="260" frameborder="0" allowfullscreen="allowfullscreen"></iframe></figure> <h2>Humans like co-operation and pleasant surprises</h2> <p>Humans have <a href="https://royalsocietypublishing.org/doi/10.1098/rspb.2022.0128">evolved to enjoy co-operation</a>, which might also help explain why we enjoy seeing co-operation between different animal species. <a href="https://www.abc.net.au/listen/programs/lifematters/competition-versus-cooperation:-which-human-instinct-is-stronge/10291360">Some scholars</a> suggest the human instinct for co-operation is even stronger than our instinct for competition.</p> <p>Another reason we may be drawn to unlikely animal friendships is that they are, in fact, so unlikely. These interactions are surprising, and research shows humans <a href="https://www.scientificamerican.com/article/neuroscientists-learn-why/">enjoy being surprised</a>.</p> <p>Our brain has <a href="https://www.imperial.ac.uk/news/239331/study-reveals-human-brains-have-evolved/">evolved to be incredibly efficient</a> at categorising, solving problems and learning. Part of the reason we’re so efficient is because we are motivated to seek new knowledge and question what we think we know. In other words, we’re motivated to be <a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC4635443/">curious</a>.</p> <p>Inter-species friendships are indeed a very curious thing. They contradict the more common assumption and observation that different species stick with their own kind. We might think “cats eat birds, so they must not like each other”. So when we see <a href="https://www.youtube.com/watch?v=bGsN7jzp5DE">a cat and a bird</a> getting along like old pals, this challenges our concept of how the natural world works.</p> <figure><iframe src="https://www.youtube.com/embed/bGsN7jzp5DE?wmode=transparent&amp;start=0" width="440" height="260" frameborder="0" allowfullscreen="allowfullscreen"></iframe></figure> <p>Neuroscientists have documented that, when surprised, humans experience a release of brain chemicals responsible for making us <a href="https://www.scientificamerican.com/article/unexpected-brain-chemistry-is-behind-the-element-of-surprise/">more alert</a> and <a href="https://www.sciencedirect.com/science/article/pii/S0896627320308539">sensitive to reward</a>. It is this neurochemical reaction that produces the “pleasantness” in the feeling of being pleasantly surprised.</p> <h2>A desire for peace and harmony</h2> <p>Perhaps another explanation for why humans are so intrigued by inter-species friendships is because they feed a human desire for peace and harmony.</p> <p>These connections may be symbolic of what many people yearn for: a world where differences can be put aside in favour of a peaceful co-existence. These friendships might even prompt us to imagine, consciously or subconsciously, a future in which we become more enlightened as a species.</p> <p>One could argue a key reason behind the success of the TV series <a href="https://www.youtube.com/watch?v=ANnFNfVuZeM">Star Trek</a> is its <a href="https://jacobin.com/2023/08/star-trek-solidarity-utopianism-technology-postcapitalism">optimistic take on the future of humanity</a>. Inter-species co-operation is a central theme of the show.</p> <p>Inter-species friendships may serve as a concrete example of breaking free of the “natural” way of being for a more peaceful way of being. And while it might only be a dream, it’s nice to watch cute animal videos that help us feel like this dream might be possible.<!-- Below is The Conversation's page counter tag.

New study reveals people who do this daily make more money over their lifetimes

<p>You’ve heard that regular exercise can help you live richly. Frequent movement, even in short bursts throughout the day, has been linked to lower all-cause mortality rates and reduced risk of heart disease, type-2 diabetes and other age-related conditions, helping you age healthfully and stay independent.</p> <p>Now, new research suggests frequent exercise might help you live well in another meaningful way; in terms of income. In a recent study published in the journal Clinical Orthopaedics and Related Research, doctors from the National Institute of Arthritis and Musculoskeletal and Skin Diseases (NIAMS), which is part of the National Institute of Health (NIH), investigated whether individuals who stayed active would earn more money as a result of their active lifestyle.</p> <p>The researchers’ findings revealed that staying active not only resulted in higher present earnings, but also predicted increased future income throughout one’s life. In essence, the science was clear: Getting more exercise could make you wealthier.</p> <h2>How exercise predicted future earnings</h2> <p>The researchers set out to explore three key correlations: How mobility affected income, how mobility influenced income over time, and whether exercise could help people maintain their mobility as they aged.</p> <p>The team analysed data from the US-federally-supported Health and Retirement Study (HRS), the largest study tracking changes over time in Americans aged 50 and above. This comprehensive study takes into account various life aspects, including work, socio-economic status, health, psychology and family matters, as individuals age.</p> <p>To assess the impact of current mobility on income, the researchers examined data from over 19,000 respondents to determine how well they could perform simple tasks, such as walking several blocks, climbing multiple flights of stairs, or moving around a room. Each person received a numerical score, with 5 indicating full mobility and 0 indicating difficulties with these tasks.</p> <h2>What earnings over time revealed</h2> <p>The researchers found that for each decrease in the mobility category, individuals lost out on an average of US$3000 in annual income compared to their peers. Those who were active were also significantly more likely to remain working for longer than the other group. It appeared that engaging in exercise enabled individuals to maintain mobility and engage in professional life for a longer period of time than those who were less active.</p> <p>Looking at earnings over time revealed even more substantial benefits for those who remained active throughout their lives. Active individuals showed an overall income level that was US$6500 higher, along with higher rates of employment.</p> <p>For the third part of the study, it’s not surprising that those who engaged in exercise continued to maintain their mobility after the age of 55 and had higher employment rates. Even exercising just one day a week showed improvements in mobility outcomes.</p> <h2>Moving more benefits more than just health</h2> <p>While this study doesn’t definitively prove that leading a healthy lifestyle directly leads to higher earnings, it strongly suggests that staying healthy and mobile brings benefits beyond just lower levels of disease (which is a type of wealth in and of itself). NIAMS Director Lindsey A. Criswell, M.D., M.P.H., underscores this point: “We have long understood that greater mobility is an important indicator of good health … The notion that mobility can have economic rewards further extends the evidence for the benefits of exercise and maintaining an active lifestyle.”</p> <p>If this science inspires you to make a healthy lifestyle change, speak with a licensed healthcare provider to determine the right exercise programme for you.</p> <p><em>Image credits: Shutterstock </em></p> <p><em>This article originally appeared on <a href="https://www.readersdigest.co.nz/food-home-garden/money/new-study-reveals-people-who-do-this-daily-make-more-money-over-their-lifetimes" target="_blank" rel="noopener">Reader's Digest</a>.</em> </p>

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

<p>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.</p> <p>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.</p> <p>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 <em>The Journal of Nutrition, Health, and Aging</em>. 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.</p> <h2>What daily diets revealed</h2> <p>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.</p> <p>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.</p> <h2>Vegetables that help protect cognition</h2> <p>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.”</p> <p>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.</p> <p>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.)</p> <h2>Fruit that pack a punch</h2> <p>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.</p> <p>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.</p> <p><em>Image credits: Shutterstock</em></p> <p><em>This article originally appeared on <a href="https://www.readersdigest.co.nz/healthsmart/want-to-reduce-your-dementia-risk-eat-these-4-foods-says-new-study" target="_blank" rel="noopener">Reader's Digest</a>. </em></p>

Elephant tourism often involves cruelty – here are steps toward more humane, animal-friendly excursions

<p><em><a href="https://theconversation.com/profiles/michelle-szydlowski-1495781">Michelle Szydlowski</a>, <a href="https://theconversation.com/institutions/miami-university-1934">Miami University</a></em></p> <p>Suju Kali is a 50-year-old elephant in Nepal who has been carrying tourists for over 30 years. Like many elephants I encounter through my <a href="https://doi.org/10.1080/10888705.2022.2028628">research</a>, Suju Kali exhibits anxiety and can be aggressive toward strangers. She suffers from emotional trauma as a result of prolonged, commercial human contact.</p> <p>Like Suju Kali, many animals are trapped within the tourism industry. Some venues have no oversight and little concern for animal or tourist safety. Between 120,000 and 340,000 animals are used globally in a variety of wildlife tourism attractions, including <a href="https://doi.org/10.1371/journal.pone.0138939">endangered species</a> like elephants. Over a quarter of the world’s <a href="https://www.iucnredlist.org/species/7140/45818198">endangered elephants</a> reside in captivity with little oversight.</p> <p>Wildlife tourism – which involves viewing wildlife such as primates or birds in conservation areas, feeding or touching captive or “rehabilitated” wildlife in facilities, and bathing or riding animals like elephants – is <a href="https://doi.org/10.1080/14724049.2022.2156523">tricky business</a>. I know this because I am <a href="https://scholar.google.com/citations?user=YbweA2MAAAAJ&amp;hl=en">a researcher studying human relationships with elephants</a> in both tourism and conservation settings within Southeast Asia.</p> <p>These types of experiences have long been an <a href="https://kathmandupost.com/money/2021/06/17/tourism-is-nepal-s-fourth-largest-industry-by-employment-study">extremely popular and profitable</a> part of the <a href="https://journals.plos.org/plosbiology/article?id=10.1371/journal.pbio.1002074">tourism market</a>. But now, many travel-related organizations are urging people not to participate in, or <a href="https://www.usatoday.com/story/travel/destinations/2018/04/27/animal-welfare-travelers-how-enjoy-wildlife-without-harming/544938002/">calling for an outright ban on, interactive wildlife experiences</a>.</p> <p>Tourism vendors have started marketing more “ethical options” for consumers. Some are attempting to truly improve the health and welfare of wildlife, and some are transitioning captive wildlife into touch-free, non-riding or lower-stress environments. In other places, organizations are attempting to <a href="https://www.fao.org/documents/card/es/c/b2c5dad0-b9b9-5a3d-a720-20bf3b9f0dc2/">implement standards of care</a> or create manuals that outline good practices for animal husbandry.</p> <p>This marketing, academics argue, is often simply “<a href="https://doi.org/10.1016/j.gecco.2017.11.007">greenwashing</a>,” <a href="http://dx.doi.org/10.1080/13683500.2023.2280704">applying marketing labels to make consumers feel better</a> about their choices without making any real changes. Worse, research shows that some programs marketing themselves as ethical tourism may instead be widening economic gaps and harming both humans and other species that they are meant to protect.</p> <h2>No quick fix</h2> <p>For example, rather than tourist dollars trickling down to local struggling families as intended by local governments, many tourism venues are owned by nonresidents, <a href="http://dx.doi.org/10.3126/japfcsc.v2i1.26746">meaning the profits do not stay in the area</a>. Likewise, only a small number of residents can afford to own tourism venues, and venues do not provide employment for locals from lower income groups.</p> <p>This economic gap is especially obvious in Nepalese elephant stables: Venue owners continue to make money off elephants, while elephant caregivers continue to work 17 hours a day for about US$21 a month; tourists are led to believe they are “<a href="https://www.cabidigitallibrary.org/doi/book/10.1079/9781800624498.0000">promoting sustainability</a>.”</p> <p>Yet, there are no easy answers, especially for elephants working in tourism. Moving them to sanctuaries is difficult because with no governmental or global welfare oversight, elephants may end up in worse conditions.</p> <p>Many kindhearted souls who want to “help” elephants know little about their biology and mental health needs, or what it takes to keep them healthy. Also, feeding large animals like Suju Kali is pricey, <a href="https://doi.org/10.3390/ani14010171">costing around $19,000 yearly</a>. So without profits from riding or other income, owners – or would-be rescuers – can’t maintain elephants. Releasing captive elephants to the jungle is not a choice – many have never learned to live in the wild, so they cannot survive on their own.</p> <h2>Hurting local people</h2> <p>Part of the problem lies with governments, as many have marketed tourism as a way to fund conservation projects. For example in Nepal, a percentage of ticket sales from elephant rides are given to community groups to use for forest preservation and support for local families.</p> <p>Increasing demand for <a href="https://www.routledge.com/Tourism-and-Animal-Ethics/Fennell/p/book/9781032431826">wildlife-based tourism</a> may increase traffic in the area and thus put pressure on local governments to further limit local people’s access to forest resources.</p> <p>This may also lead to <a href="https://www.worldanimalprotection.org/latest/news/un-world-tourism-organisation-urged-create-better-future-animals/">increased demands on local communities</a>, as was the case in Nepal. In the 1970s, the Nepalese government removed local people from their lands in what is now Chitwan National Park as part of increasing “conservation efforts” and changed the protected area’s boundaries. Indigenous “Tharu,” or people of the forest, were forced to abandon their villages and land. While some were offered access to “buffer zones” in the 1990s, many remain poor and landless today.</p> <p>In addition, more and more desirable land surrounding conservation areas in Nepal is being developed for tourist-based businesses such as hotels, restaurants and shops, <a href="http://dx.doi.org/10.3126/japfcsc.v2i1.26746">pushing local poor people farther away</a> from central village areas and the associated tourism income.</p> <p>Some activists would like humans to simply release all wildlife back into the wild, but <a href="https://www.cabidigitallibrary.org/doi/book/10.1079/9781800624498.0000">there are multiple issues</a> with that. Elephant habitats throughout Southeast Asia have been transformed into croplands, cities or train tracks for human use. Other problems arise from the fact that tourism elephants have <a href="https://doi.org/10.4324/9781315457413">never learned</a> how to be elephants in their natural elements, as they were <a href="https://www.pugetsound.edu/sites/default/files/file/8342_Journal%20of%20Tourism%20%282009%29_0.pdf">separated from their herds</a> at an early age.</p> <p>So tourism may be vital to providing food, care and shelter to captive elephants for the rest of their lives and providing jobs for those who really need them. Because elephants can live beyond 60 years, this can be a large commitment.</p> <h2>How to be an ethical tourist</h2> <p>To protect elephants, tourists should check out reviews and photos from any venue they want to visit, and look for clues that animal welfare might be impacted, such as tourists allowed to feed, hold or ride captive wildlife animals. Look for healthy animals, which means doing research on what “healthy” animals of that species should look like.</p> <p>If a venue lists no-touch demonstrations – “unnatural” behaviors that don’t mimic what an elephant might do of their own accord, such as sitting on a ball or riding a bike, or other performances – remember that the behind-the-scenes training used to achieve these behaviors can be <a href="https://doi.org/10.21832/9781845415051-014">violent, traumatic or coercive</a>.</p> <p>Another way to help people and elephant is to to use small, local companies to book your adventures in your area of interest, rather than paying large, international tourism agencies. Look for locally owned hotels, and wait to book excursions until you arrive so you can use local service providers. Book homestay programs and attend cultural events led by community members; talk to tourists and locals you meet in the target town to get their opinions, and use local guides who provide wildlife viewing opportunities <a href="https://nepaldynamicecotours.com/">while maintaining distance from animals</a>.</p> <p>Or tourists can ask to visit <a href="https://www.americanhumane.org/press-release/global-humane-launches-humane-tourism-certification-program/">venues that are certified</a> by international humane animal organizations and that <a href="https://www.su4e.org/">do not allow contact</a> with wildlife. Or they can opt for guided hikes, canoe or kayak experiences, and other environmentally friendly options.</p> <p>While these suggestions will not guarantee that your excursion is animal-friendly, they will help decrease your impact on wildlife, support local families and encourage venues to stop using elephants as entertainment. Those are good first steps.<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/219792/count.gif?distributor=republish-lightbox-basic" alt="The Conversation" width="1" height="1" /></p> <p><em><a href="https://theconversation.com/profiles/michelle-szydlowski-1495781">Michelle Szydlowski</a>, Visiting Assistant Professor, Department of Biology, Project Dragonfly, <a href="https://theconversation.com/institutions/miami-university-1934">Miami University</a></em></p> <p><em>Image credits: Getty Images </em></p> <p><em>This article is republished from <a href="https://theconversation.com">The Conversation</a> under a Creative Commons license.

Science finally proves "Money doesn't buy happiness"

<p>A new study has proven that the old adage "money can't buy you happiness" is true. </p> <p>Historically, economic wealth and higher income households are often seen to have an increased level of wellbeing and happiness, with the extra money making way for less stress and more general comfortability. </p> <p>However, researchers from Canada and Spain have concluded this may not be true, with such surveys often including responses from people in industrialised areas only. </p> <p>People in small-scale societies where money does not play a central role in every day life are often excluded from these studies, as the livelihood of residents in these small communities usually depend more on nature. </p> <p>Now, 2,966 people from Indigenous and local communities in 19 locations across the globe have been included in a study, with researchers now finding that societies of Indigenous people and those in small, local communities report living very satisfying lives despite not having a lot of money. </p> <p>The researchers wrote, "The striking aspect of our findings... is that reported life satisfaction in very low-income communities can meet and even exceed that reported at the highest average levels of material wealth provided by industrial ways of life."</p> <p>Researchers concluded the findings are strong evidence that economic growth is not needed to be happy, with only 64 percent of households included in the survey reported having any cash income.</p> <p>Eric Galbraith, lead author of the study, said, "Surprisingly, many populations with very low monetary incomes report very high average levels of life satisfaction, with scores similar to those in wealthy countries."</p> <p>Researchers added that high life satisfaction is shown in these communities "despite many of these societies having suffered histories of marginalisation and oppression."</p> <p>Galbraith added, "I would hope that, by learning more about what makes life satisfying in these diverse communities, it might help many others to lead more satisfying lives while addressing the sustainability crisis."</p> <p><em>Image credits: Shutterstock</em></p>

Is it okay to kiss your pet? The risk of animal-borne diseases is small, but real

So, it’s important to know the risks and take necessary precautions to prevent infections.</p> <h2>What diseases can pets carry?</h2> <p>Infectious diseases that move from animals to humans are called zoonotic diseases or <a href="https://www.cdc.gov/onehealth/basics/zoonotic-diseases.html">zoonoses</a>. More than <a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC3668296/#B18">70 pathogens</a> of companion animals are known to be transmissible to people.</p> <p>Sometimes, a pet that has a zoonotic pathogen may look sick. But often there may be no visible symptoms, making it easier for you to catch it, because you don’t suspect your pet of harbouring germs.</p> <p>Zoonoses can be transmitted directly from pets to humans, such as through contact with saliva, bodily fluids and faeces, or indirectly, such as through contact with contaminated bedding, soil, food or water.</p> <p>Studies suggest <a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC4500695/">the prevalence of pet-associated zoonoses is low</a>. However, the true number of infections is likely <a href="https://www.mdpi.com/1660-4601/17/11/3789">underestimated</a> since many zoonoses are not “<a href="https://www.healthdirect.gov.au/notification-of-illness-and-disease">notifiable</a>”, or may have multiple exposure pathways or generic symptoms.</p> <p>Dogs and cats are major reservoirs of zoonotic infections (meaning the pathogens naturally live in their population) caused by viruses, bacteria, fungi and parasites. <a href="https://www.who.int/data/gho/data/themes/topics/rabies">In endemic regions in Africa and Asia</a>, dogs are the main source of rabies which is transmitted through saliva.</p> <p>Dogs also commonly carry <em>Capnocytophaga</em> bacteria <a href="https://www.cdc.gov/capnocytophaga/index.html">in their mouths and saliva</a>, which can be transmitted to people through close contact or bites. The vast majority of people won’t get sick, but these bacteria can occasionally cause infections in people with weakened immune systems, <a href="https://www.cdc.gov/capnocytophaga/signs-symptoms/index.html">resulting</a> in severe illness and sometimes death. Just last week, such a death <a href="https://thewest.com.au/news/wa/tracy-ridout-perth-mum-dies-11-days-after-rare-bacterial-infection-from-minor-dog-bite-c-11748887">was reported in Western Australia</a>.</p> <p>Cat-associated zoonoses include a number of illnesses spread by the faecal-oral route, such as giardiasis, campylobacteriosis, salmonellosis and toxoplasmosis. This means it’s especially important to wash your hands or use gloves whenever handling your cat’s litter tray.</p> <p>Cats can also sometimes transmit infections through bites and scratches, including the aptly named <a href="https://www.cdc.gov/healthypets/diseases/cat-scratch.html#:%7E:text=Cat%20scratch%20disease%20(CSD)%20is,the%20surface%20of%20the%20skin.">cat scratch disease</a>, which is caused by the bacterium <em>Bartonella henselae</em>.</p> <p>Both dogs and cats are also reservoirs for <a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC10122942/">methicillin-resistant bacterium <em>Staphylococcus aureus</em></a> (MRSA), with close contact with pets identified as an important risk factor for zoonotic transmission.</p> <h2>Birds, turtles and fish can also transmit disease</h2> <p>But it’s not just dogs and cats that can spread diseases to humans. Pet birds can occasionally transmit <a href="https://www.cdc.gov/pneumonia/atypical/psittacosis/">psittacosis</a>, a bacterial infection which causes pneumonia. Contact with <a href="https://www.fda.gov/animal-veterinary/animal-health-literacy/pet-turtles-source-germs">pet turtles</a> has been linked to <em>Salmonella</em> infections in humans, particularly in young children. Even pet fish have been linked to a <a href="https://www.cdc.gov/healthypets/pets/fish.html">range of bacterial infections</a> in humans, including vibriosis, mycobacteriosis and salmonellosis.</p> <p>Close contact with animals – and some behaviours in particular – increase the risk of zoonotic transmission. <a href="https://pubmed.ncbi.nlm.nih.gov/19398275/">A study from the Netherlands</a> found half of owners allowed pets to lick their faces, and 18% allowed dogs to share their bed. (Sharing a bed increases the duration of exposure to pathogens carried by pets.) The same study found 45% of cat owners allowed their cat to jump onto the kitchen sink.</p> <p>Kissing pets has also been linked to occasional zoonotic infections in pet owners. <a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC3298380/">In one case</a>, a woman in Japan developed meningitis due to <em>Pasteurella multicoda</em> infection, after regularly kissing her dog’s face. These bacteria are often found in the oral cavities of dogs and cats.</p> <p>Young children are also more likely to engage in behaviours which increase their risk of <a href="https://www.cdc.gov/healthypets/specific-groups/high-risk/children.html?CDC_AA_refVal=https%3A%2F%2Fwww.cdc.gov%2Fhealthypets%2Fspecific-groups%2Fchildren.html">getting sick</a> from animal-borne diseases – such as putting their hands in their mouth after touching pets. Children are also less likely to wash their hands properly after handling pets.</p> <p>Although anybody who comes into contact with a zoonotic pathogen via their pet can become sick, certain people are more likely to suffer from serious illness. These people include the young, old, pregnant and immunosuppressed.</p> <p>For example, while most people infected with the toxoplasmosis parasite will experience only mild illness, it can be life-threatening or <a href="https://www.nhs.uk/common-health-questions/pregnancy/what-are-the-risks-of-toxoplasmosis-during-pregnancy/">cause birth defects in foetuses</a>.</p> <h2>What should I do if I’m worried about catching a disease from my pet?</h2> <p>There are a number of good hygiene and pet husbandry practices that can reduce your risk of becoming sick. These include:</p> <ul> <li>washing your hands after playing with your pet and after handling their bedding, toys, or cleaning up faeces</li> <li>not allowing your pets to lick your face or open wounds</li> <li>supervising young children when they are playing with pets and when washing their hands after playing with pets</li> <li>wearing gloves when changing litter trays or cleaning aquariums</li> <li>wetting bird cage surfaces when cleaning to minimise aerosols</li> <li>keeping pets out of the kitchen (especially cats who can jump onto food preparation surfaces)</li> <li>keeping up to date with preventative veterinary care, including vaccinations and worm and tick treatments</li> <li>seeking veterinary care if you think your pet is unwell.</li> </ul> <p>It is especially important for those who are at a higher risk of illness to take precautions to reduce their exposure to zoonotic pathogens. And if you’re thinking about getting a pet, ask your vet which type of animal would best suit your personal circumstances.<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/210898/count.gif?distributor=republish-lightbox-basic" alt="The Conversation" width="1" height="1" /></p> <p><em><a href="https://theconversation.com/profiles/sarah-mclean-1351935">Sarah McLean</a>, Lecturer in environmental health, <a href="https://theconversation.com/institutions/swinburne-university-of-technology-767">Swinburne University of Technology</a> and <a href="https://theconversation.com/profiles/enzo-palombo-249510">Enzo Palombo</a>, Professor of Microbiology, <a href="https://theconversation.com/institutions/swinburne-university-of-technology-767">Swinburne University of Technology</a></em></p> <p><em>Image credits: Getty </em><em>Images </em></p> <p><em>This article is republished from <a href="https://theconversation.com">The Conversation</a> under a Creative Commons license.

An expert’s top 5 reasons why dogs can be considered exceptional animals

<p><em><a href="https://theconversation.com/profiles/melissa-starling-461103">Melissa Starling</a>, <a href="https://theconversation.com/institutions/university-of-sydney-841">University of Sydney</a></em></p> <p>Dogs are important to a lot of humans, but what makes them so?</p> <p>Apart from being warm, soft and capable of inspiring our unconditional love, there are a number of unique characteristics that set dogs apart from other animals.</p> <p>As a dog researcher, animal behaviour consultant and canophile (which means I <em>love</em> dogs), let me share five traits that I think make dogs so special.</p> <h2>Dogs are hypersocial</h2> <p>We all know those golden retriever-type dogs that appear absurdly delighted to meet any new social being. It’s hard not to be taken in by their infectious friendliness. These furry, hypersocial creatures have some key genetic differences even to other domestic dogs.</p> <p>Most fascinatingly, these genetic differences are in the area of the genome <a href="https://www.insidescience.org/news/rare-human-syndrome-may-explain-why-dogs-are-so-friendly">associated</a> with hypersociability in people with a genetic condition called Williams-Beuren syndrome. Although people with this syndrome experience negative health effects, they also tend to be very open, engaging and sociable.</p> <p>Not all dogs fall into this hypersocial category – but even those that don’t are unusually accepting of unfamiliar people and dogs.</p> <p>Unlike other social wild canids such as wolves, domestic dogs can quite happily live in harmony with different species, as well as individuals of their own species that aren’t from their family. This is what makes it so easy to slot dogs into our lives.</p> <h2>Dogs are wired to understand us</h2> <p>Humans have selectively bred dogs for many generations. And in many cases, we’ve bred them to take direction to help us in a wide variety of jobs – including being companions to us. This has led to domestic dogs being born with an interest in humans.</p> <p>From an early age, <a href="https://www.sciencedirect.com/science/article/pii/S0960982221006023">puppies are attracted</a> to human faces. While dogs are as co-operative as wolves, they tend to be submissive towards humans and follow our directions – whereas wolves are bolder and more likely to lead when <a href="https://www.pnas.org/doi/10.1073/pnas.1709027114">co-operating with humans</a>.</p> <p>Dogs also learn to follow our gaze, and show a left-gaze bias when looking at human faces. This means they spend more time looking at the left side of our faces (which would be the right side from our perspective). This bias emerges in several species when they are processing emotional information, which shows that dogs are <a href="https://journals.plos.org/plosone/article?id=10.1371/journal.pone.0152393">reading our faces</a> to figure out how we’re feeling.</p> <p>For a while it was also thought dogs were particularly attentive to human gestures such as pointing – but recent research suggests many domestic species and some wild animal species can also <a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC7555673/">follow pointing</a>.</p> <h2>Dogs come in countless shapes and sizes</h2> <p>No other species comes in such a huge variety of shapes and sizes as domestic dogs. Not even cats or horses display the same diversity.</p> <p>The largest dogs may be close to 25 times the size of the smallest! Beyond that, we have dogs with drop ears and prick ears and everything in between, tails and no tails, or bob tails, short legs and long legs, long noses and short noses – and a huge variety of coat colours, lengths and textures.</p> <p>For dogs, this huge variation might mean they have more to learn than other animals when it comes to understanding their own kind. For example, owners of herding breed dogs may find their dog a bit confused, or even defensive, when meeting a very different short-faced breed such as a bulldog.</p> <p>For us, it means we should appreciate how the size and shape of dogs can influence <a href="https://journals.plos.org/plosone/article?id=10.1371/journal.pone.0149403">their behaviour</a> and experiences. For instance, dogs with longer noses have sharper vision, while dogs with a lighter build tend to be more energetic and fearful.</p> <h2>Dogs form deep emotional bonds</h2> <p>Domestic dogs have been shown to form attachment bonds with human caregivers that are very similar to those formed between <a href="https://journals.plos.org/plosone/article?id=10.1371/journal.pone.0065296">children and parents</a>.</p> <p>This may partly explain why they can read our <a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC10426098/">emotional signals</a>, why they become distressed (and try to help us) when <a href="https://journals.plos.org/plosone/article?id=10.1371/journal.pone.0231742">we are distressed</a>, and why MRI studies show dogs are happy when they smell <a href="https://www.sciencedirect.com/science/article/pii/S0376635714000473">their owners</a>.</p> <p>It may also be why they panic when separated from us. Dogs’ attachment to humans goes beyond being hypersocial. To them, we are a lot more than the food we provide and the balls we throw. We are an attachment figure akin to a parent.</p> <h2>Dogs can help us be our best selves</h2> <p>Most dog owners would agree their dog brings out the best in them. They can confide in their dog and love them unconditionally – sometimes more easily than they can another human.</p> <p>Dogs are playing important roles in animal-assisted therapy, where their nonjudgmental presence can be a calming influence and <a href="https://link.springer.com/article/10.1007/s40489-019-00188-5">facilitate social interactions</a>. They can even help children <a href="https://link.springer.com/article/10.1007/s10643-022-01392-5">learn to read</a> and <a href="https://www.mdpi.com/2077-0383/10/21/5171">alleviate anxiety</a>.</p> <p>Although assisting humans with their emotional problems can be a difficult task for such an emotionally sensitive species, research suggests the right dogs can rise to the task if their workload is <a href="https://www.sciencedirect.com/science/article/pii/S1558787818302193">managed carefully</a>.</p> <p>Horses are also used in animal-assisted therapy, as are some smaller furry animals. However, dogs are more portable and can remain at ease in stimulating environments such as courtrooms, schools and airports. They are uniquely placed to accompany us wherever we go.</p> <h2>Paws for thought</h2> <p>We might like to think dogs are special for some of the traits we value in humans, such as intelligence, selflessness or a loving nature. But really dogs are exceptional for simply being dogs.</p> <p>They are social acrobats that can find social harmony wherever they go. They have rich emotional lives in which they co-exist with different species and can even forge bonds <a href="https://www.youtube.com/watch?v=89dCR3VinMM&amp;ab_channel=WCCO-CBSMinnesota">outside of their own species</a>.</p> <p>They are also generally tolerant of our primate ways – and good at receiving our love. And for me that’s enough.<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/211832/count.gif?distributor=republish-lightbox-basic" alt="The Conversation" width="1" height="1" /></p> <p><em><a href="https://theconversation.com/profiles/melissa-starling-461103">Melissa Starling</a>, Postdoctoral Researcher in Veterinary Science, <a href="https://theconversation.com/institutions/university-of-sydney-841">University of Sydney</a></em></p> <p><em>Image credits: Shutterstock</em></p> <p><em>This article is republished from <a href="https://theconversation.com">The Conversation</a> under a Creative Commons license.

10 reasons humans kill animals – and why we can’t avoid it

<p><em><a href="https://theconversation.com/profiles/benjamin-allen-100036">Benjamin Allen</a>, <a href="https://theconversation.com/institutions/university-of-southern-queensland-1069"><em>University of Southern Queensland</em></a></em></p> <p>As long as humans have existed, they’ve killed animals. But the necessity of some types of animal killing are now questioned by many. So can humans ever stop killing animals entirely? And if not, what’s the best way forward?</p> <p><a href="https://www.sciencedirect.com/science/article/pii/S0048969723039062">New research</a> I led investigates these questions. My colleagues and I identified the ten main reasons why humans kill animals. We found the need for some types of animal killing is questionable, but several forms are inescapable – a necessary part of humanity’s involvement in a single, functioning, finite global food web.</p> <p>But the debate doesn’t end there. Even if humans must kill animals in some cases, they can modify their behaviours to improve the welfare of animals while they are alive, and to reduce an animal’s suffering when it is killed.</p> <p>Doing so may improve the lives of animals to a greater extent than efforts to eliminate human killing entirely.</p> <h2>Why humans kill animals</h2> <p>Critics of animal-killing come from a variety of perspectives. Some oppose it on <a href="http://refhub.elsevier.com/S0048-9697(23)03906-2/rf0005">moral grounds</a>. Others claim animals should have <a href="https://conbio.onlinelibrary.wiley.com/doi/10.1111/cobi.13494">rights equal</a> to humans, and say animal killing is a criminal act. Many people view any animal killing as <a href="https://conbio.onlinelibrary.wiley.com/doi/10.1111/cobi.13126">cruel</a>, regardless of whether the animal suffers.</p> <p>But as valid and important as these views might be, they largely fail to address <em>why</em> humans kill animals – and why in many cases, it can’t be avoided. Our research sought to shed light on this.</p> <p>We focus our discussion on vertebrate animals which are almost universally recognised as “sentient” (or able to perceive and feel things). We identified ten main reasons humans kill animals:</p> <p><strong>1. Wild harvest or food acquisition:</strong> such as killing wild animals for meat</p> <p><strong>2. Human health and safety:</strong> such as reactively killing an animal when it attacks you</p> <p><strong>3. Agriculture and aquaculture:</strong> such as killing that occurs in the global meat industries, or killing required to produce crops</p> <p><strong>4. Urbanisation and industrialisation:</strong> such as clearing bushland to build homes</p> <p><strong>5. Wildlife control:</strong> such as programs that eradicate introduced animals to stop them killing native ones</p> <p><strong>6. Threatened species conservation:</strong> such as unintentionally killing animals when relocating them</p> <p><strong>7. Recreation, sport or entertainment:</strong> such as trophy hunting or bull fighting, and animal killing required to feed domestic pets</p> <p><strong>8. Mercy or compassion:</strong> such as euthanasing an animal hit by a car</p> <p><strong>9. Cultural and religious practice:</strong> such as animal sacrifice during the Islamic celebration of <a href="https://www.theguardian.com/world/2023/jul/01/sydney-muslims-take-eid-al-adha-livestock-sacrifice-into-their-own-hands">Eid al-Adha</a>, or those associated with the <a href="https://www.jstor.org/stable/1594756">Yoruba</a> religion of West Africa</p> <p><strong>10. Research, education and testing:</strong> such as the laboratory use of rodents or primates.</p> <h2>Understanding human killing behaviour</h2> <p>So how best should we understand the above types of animal killing? Our research considers them in ecological terms – as behaviours consistent with our predatory and competitive roles in the global food web. Such behaviours are intended to improve human prospects for acquiring food or to protect and enhance life. These are innate life objectives for any sentient animal.</p> <p>Maintenance of all life on Earth requires obtaining, using, disposing of and recycling chemical elements. Ecosystems can be thought of as a “battleground” for these elements.</p> <p><a href="https://theconversation.com/peter-singers-fresh-take-on-animal-liberation-a-book-that-changed-the-world-but-not-enough-205830">Some people argue</a> that directly killing animals is unacceptable, or that adopting certain lifestyles or diets, such as veganism, can eliminate or greatly reduce animal killing. But in our view, achieving a no-killing lifestyle is a physical and ecological impossibility.</p> <p>For instance, most plant foods come from crops grown on land where animals have been <a href="https://www.mdpi.com/2076-2615/11/5/1225">killed or displaced</a>. And while an animal-free diet for humans might temporarily reduce the number of animals killed, this won’t last forever. As human populations continue to grow, more land will eventually be needed to meet their food requirements. At that point, humans will have to directly or indirectly kill animals again or risk dying themselves.</p> <p>Humans also need space to live, which <a href="https://www.sciencedirect.com/science/article/pii/S0048969723039062?ref=pdf_download&amp;fr=RR-2&amp;rr=7e2e8f44ae1aaae3#bbb1045">results in</a> animal killing when habitat is razed.</p> <p>Of course, in rare cases an individual human may live without killing animals directly. Perhaps they live in a cave in the forest, and get sustenance from wild berries and mushrooms. But that human still lives inside the food web, and is competing against other animals for finite resources. In these cases, other animals may suffer and die because the human’s use of berries and caves leaves less food and space for them.</p> <p>Even if that human could do no harm at all to any animal, it’s still impossible for societies at large to live in this way.</p> <p>Some forms of animal killing are certainly not essential for human existence. Good examples are recreational hunting, euthanasia or keeping pets (which requires killing animals to feed them). And we certainly do not condone direct human participation in all forms of animal killing.</p> <p>It’s also important to note that in many cases, current levels of animal killing are <a href="https://www.opsociety.org/stop-unsustainable-fishing/">unsustainable</a>. Human populations have increased to the point where animals must be killed on enormous scales to feed, house and protect ourselves. If this continues, animal <a href="https://www.sciencedirect.com/science/article/pii/S0048969723039062?ref=pdf_download&amp;fr=RR-2&amp;rr=7e2e8f44ae1aaae3#bbb0905">populations</a> will <a href="https://www.sciencedirect.com/science/article/pii/S0048969723039062?ref=pdf_download&amp;fr=RR-2&amp;rr=7e2e8f44ae1aaae3#bbb0910">crash</a> – and with them, human populations.</p> <p>Nevertheless, we maintain that the overall necessity of animal killing is an unavoidable reality for humanity as a whole. A variety of direct and indirect forms of animal killing will undoubtedly remain an ongoing human endeavour.</p> <h2>Taking responsibility</h2> <p>So what are the implications of all this? We hope our research leads to a constructive dialogue, which starts with accepting that human existence on Earth is dependent on animal killing. It should then focus on the nuances of animal welfare and sustainability.</p> <p>Humans are the only known animals with an ethical or moral conscience. That means we have <a href="https://www.sciencedirect.com/science/article/pii/S0048969723039062?ref=pdf_download&amp;fr=RR-2&amp;rr=7e2e8f44ae1aaae3#bbb0650">a responsibility</a> to assume a stewardship role over all other animals, to resolve negative interactions between them as best as possible, and to ensure good welfare for as many animals as we can.</p> <p>Directing our attention in this way is likely to improve the lives of animals to a greater extent than trying to prevent humans from killing animals altogether – efforts my colleagues and I believe will ultimately be in vain.<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/209218/count.gif?distributor=republish-lightbox-basic" alt="The Conversation" width="1" height="1" /></p> <p><a href="https://theconversation.com/profiles/benjamin-allen-100036"><em>Benjamin Allen</em></a><em>, Wildlife ecologist, <a href="https://theconversation.com/institutions/university-of-southern-queensland-1069">University of Southern Queensland</a></em></p> <p><em>Image credits: Getty Images</em></p> <p><em>This article is republished from <a href="https://theconversation.com">The Conversation</a> under a Creative Commons license.

A change in prescribing for low back pain and neck pain is urgently needed in <a href="https://www.tga.gov.au/resources/publication/publications/addressing-prescription-opioid-use-and-misuse-australia">Australia</a> and <a href="https://www.thelancet.com/commissions/opioid-crisis">globally</a> to reduce opioid-related harms.</p> <h2>Comparing opioids to a placebo</h2> <p>In our trial, we randomly allocated 347 people with acute low back pain and neck pain to take either an opioid (oxycodone plus naloxone) or <a href="https://www.betterhealth.vic.gov.au/health/conditionsandtreatments/placebo-effect">placebo</a> (a tablet that looked the same but had no active ingredients).</p> <p>Oxycodone is an opioid pain medicine which can be given orally. <a href="https://www.nps.org.au/radar/articles/oxycodone-with-naloxone-controlled-release-tablets-targin-for-chronic-severe-pain">Naloxone</a>, an opioid-reversal drug, reduces the severity of constipation while not disrupting the pain relieving effects of oxycodone.</p> <p>Participants took the opioid or placebo for a maximum of six weeks.</p> <p>People in the both groups also received <a href="https://www.sciencedirect.com/science/article/pii/S1836955321000941">education and advice</a> from their treating doctor. This could be, for example, advice on returning to their normal activities and avoiding bed rest.</p> <p>We assessed their outcomes over a one-year period.</p> <h2>What did we find?</h2> <p>After six weeks of treatment, taking opioids did not result in better pain relief compared to the placebo.</p> <p>Nor were there benefits to other outcomes such as physical function, quality of life, recovery time or work absenteeism.</p> <p>More people in the group treated with opioids experienced nausea, constipation and dizziness than in the placebo group.</p> <p>Results at one year highlight the potential long-term harm of opioids even with short-term use. Compared to the placebo group, people in the opioid group experienced slightly worse pain, and reported a higher risk of <a href="https://academic.oup.com/painmedicine/article/20/1/113/4728236#129780622">opioid misuse</a> (problems with their thinking, mood or behaviour, or using opioids differently from how the medicines were prescribed).</p> <p>More people in the opioid group reported pain at one year: 66 people compared to 50 in the placebo group.</p> <h2>What will this mean for opioid prescribing?</h2> <p>In recent years, international low back pain guidelines have shifted the focus of treatment from drug to non-drug treatment due to <a href="https://www.thelancet.com/article/S0140-6736(18)30489-6/fulltext">evidence</a> of limited treatment benefits and concern of medication-related harm.</p> <p>For acute low back pain, <a href="https://link.springer.com/article/10.1007/s00586-018-5673-2">guidelines</a> recommend patient education and advice, and if required, anti-inflammatory pain medicines such as ibuprofen. Opioids are <a href="https://link.springer.com/article/10.1007/s00586-018-5673-2">recommended only</a> when other treatments haven’t worked or aren’t appropriate.</p> <p>Guidelines for <a href="https://pubmed.ncbi.nlm.nih.gov/33064878/">neck</a> pain similarly discourage the use of opioids.</p> <p>Our latest research clearly demonstrates the benefits of opioids do not outweigh possible harms in people with acute low back pain and neck pain.</p> <p>Instead of advising opioid use for these conditions in selected circumstances, opioids should be discouraged without qualification.</p> <h2>Change is possible</h2> <p>Complex problems such as opioid use need smart solutions, and another study we recently conducted provides convincing data opioid prescribing can be successfully reduced.</p> <p>The <a href="https://qualitysafety.bmj.com/content/30/10/825">study</a> involved four hospital emergency departments, 269 clinicians and 4,625 patients with low back pain. The intervention comprised of:</p> <ul> <li>clinician education about <a href="https://aci.health.nsw.gov.au/networks/musculoskeletal/resources/low-back-pain">evidence-based management</a> of low back pain</li> <li>patient education using posters and handouts to highlight the benefits and harms of opioids</li> <li>providing heat packs and anti-inflammatory pain medicines as alternative pain-management treatments</li> <li>fast-tracking referrals to outpatient clinics to avoid long waiting lists</li> <li>audits and feedback to clinicians on information about opioid prescribing rates.</li> </ul> <p>This intervention reduced opioid prescribing from <a href="https://qualitysafety.bmj.com/content/30/10/825">63% to 51% of low back pain presentations</a>. The <a href="https://emj.bmj.com/content/early/2023/04/02/emermed-2022-212874">reduction was sustained for 30 months</a>.</p> <p>Key to this successful approach is that we worked with clinicians to develop suitable pain-management treatments without opioids that were feasible in their setting.</p> <p>More work is needed to evaluate this and other interventions aimed at reducing opioid prescribing in other settings including GP clinics.</p> <p>A nuanced approach is often necessary to avoid causing <a href="https://theconversation.com/opioid-script-changes-mean-well-but-have-left-some-people-in-chronic-pain-156753">unintended consequences</a> in reducing opioid use.</p> <p>If people with low back pain or neck pain are using opioids, especially at higher doses over an extended period of time, it’s important they seek advice from their doctor or pharmacist before stopping these medicines to avoid <a href="https://www.healthdirect.gov.au/opioid-withdrawal-symptoms">unwanted effects when the medicines are abruptly stopped</a>.</p> <p>Our research provides compelling evidence opioids have a limited role in the management of acute low back and neck pain. The challenge is getting this new information to clinicians and the general public, and to implement this evidence into practice.<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/203244/count.gif?distributor=republish-lightbox-basic" alt="The Conversation" width="1" height="1" /></p> <p><em><a href="https://theconversation.com/profiles/christine-lin-346821">Christine Lin</a>, Professor, <a href="https://theconversation.com/institutions/university-of-sydney-841">University of Sydney</a>; <a href="https://theconversation.com/profiles/andrew-mclachlan-255312">Andrew McLachlan</a>, Head of School and Dean of Pharmacy, <a href="https://theconversation.com/institutions/university-of-sydney-841">University of Sydney</a>; <a href="https://theconversation.com/profiles/caitlin-jones-1263090">Caitlin Jones</a>, Postdoctoral Research Associate in Musculoskeletal Health, <a href="https://theconversation.com/institutions/university-of-sydney-841">University of Sydney</a>, and <a href="https://theconversation.com/profiles/christopher-maher-826241">Christopher Maher</a>, Professor, Sydney School of Public Health, <a href="https://theconversation.com/institutions/university-of-sydney-841">University of Sydney</a></em></p> <p><em>Image credits: Shutterstock</em></p> <p><em>This article is republished from <a href="https://theconversation.com">The Conversation</a> under a Creative Commons license.

Are the Oscars going to take animated films more seriously?

<p><a href="https://theconversation.com/profiles/robert-boucaut-1215760">Robert Boucaut</a>, <em><a href="https://theconversation.com/institutions/university-of-adelaide-1119">University of Adelaide</a></em></p> <p>“Animation is cinema. Animation is not a genre. And, animation is ready to be taken to the next step – we are all ready for it, please help us, keep animation in the conversation.”</p> <p>This was Guillermo del Toro’s testament accepting the Academy Award for Best Animated Feature Film in 2023 for <a href="https://www.imdb.com/title/tt1488589/">Guillermo del Toro’s Pinocchio</a>, released by Netflix. As one of the most acclaimed modern auteurs – and one who has <a href="https://www.avclub.com/guillermo-del-toro-is-going-all-in-on-animation-1850539253">announced his intention to stick with animation</a> as his preferred medium – his acceptance speech reads like a plea directly to the academy.</p> <figure><iframe src="https://www.youtube.com/embed/shW9i6k8cB0?wmode=transparent&amp;start=0" width="440" height="260" frameborder="0" allowfullscreen="allowfullscreen"></iframe></figure> <h2>Animated films at the Oscars</h2> <p>The Oscars have had a storied history of engaging with animated cinema. Since 2002, they have awarded a Best Animated Feature award, first won by Shrek. This was a time of technological innovations for 3D animation (think Toy Story or A Bug’s Life), and of standout A-list voice performances (Robin Williams in Aladdin, or Shrek’s star-studded cast).</p> <p>By including animated films as a standalone category, the Oscars ended up segregating them: animation was treated as its own thing. Beauty and the Beast broke ground as the first-ever animated nominee for the Best Picture Oscar in 1992, but only two films have achieved such a feat since.</p> <figure><iframe src="https://www.youtube.com/embed/iurbZwxKFUE?wmode=transparent&amp;start=0" width="440" height="260" frameborder="0" allowfullscreen="allowfullscreen"></iframe></figure> <p>Up (2009) and Toy Story 3 (2010) were Best Picture Oscar nominees (and Best Animated Feature winners) of their respective years. However, such recognition only came after the academy expanded its Best Picture category from five nominees to up to 10. This was a concerted effort to include more popular films in the Oscars due to waning audience interest, after Best Picture snubs of The Dark Knight and WALL-E.</p> <p>If animated films have had difficulty breaking into the Oscars’ vision of a Best Picture, then voice talent has been outright bypassed for consideration in acting categories. Since Shrek, stars have increasingly taken on voice work for animated projects in ways that elevates them from a side-hustle to key parts of their CVs.</p> <p>For instance, <a href="https://www.youtube.com/watch?v=5L1iX5JiuwI">Chris Pratt</a> and <a href="https://www.vogue.com/article/anya-taylor-joy-princess-peach-super-mario-premiere">Anya Taylor-Joy</a>’s promotional duties for The Super Mario Bros. Movie represent significant time and stardom investments for the sake of animated intellectual property.</p> <p>Yet without the physical body to observe, the Oscars have ignored voice work in animated films. The most meaningful push to have a voice performance nominated was for Scarlett Johansson’s in Her where she played a computer operating system. Johansson’s performance was nuanced, played with chemistry against her co-stars, and, ironically, Her was not an animated film.</p> <figure><iframe src="https://www.youtube.com/embed/dJTU48_yghs?wmode=transparent&amp;start=0" width="440" height="260" frameborder="0" allowfullscreen="allowfullscreen"></iframe></figure> <h2>Are things changing?</h2> <p>The <a href="https://theconversation.com/winning-everything-everywhere-all-at-once-5-experts-on-the-big-moments-at-the-oscars-2023-201661">Oscars this year</a> shifted their brand of “prestige” to value the “cinematic experience” (and box office money) in the age of streaming.</p> <p>The sweep of Everything Everywhere All at Once and Best Picture nominations for Top Gun: Maverick and Avatar: The Way of Water in 2023 signal the academy conspicuously praising populist fare for bringing audiences into the physical cinema. This then hopefully attracts <a href="https://variety.com/2023/tv/news/2023-oscar-ratings-academy-awards-audience-1235550070/">more audience eyeballs to an Oscars telecast</a> where they are likely to have actually seen some of the nominees.</p> <p>Popular film’s infiltration of the Oscars even seeped into the acting categories. Everything Everywhere All At Once’s indie cred made nominations (and three eventual wins) for its stars logical and welcome, but even Black Panther: Wakanda Forever’s Angela Bassett scored a Best Supporting Actress nomination, the first acting recognition for the Marvel Cinematic Universe. Its online fandom was instrumental here, having opined the academy’s biases against their beloved franchise.</p> <p>Now, Spider-Man: Across the Spider-Verse has arrived ahead of the 2024 Oscars race. The animated film boasts a star-studded cast, including past Oscar nominees and winners like Daniel Kaluuya and Hailee Steinfeld in key supporting roles. Shameik Moore’s lead vocal performance as Miles Morales is also exceptional. Still figuring out what it means to balance being Spider-Man with a complicated home and social life, he sounds remarkably recognisable as a modern teenager.</p> <figure><iframe src="https://www.youtube.com/embed/cqGjhVJWtEg?wmode=transparent&amp;start=0" width="440" height="260" frameborder="0" allowfullscreen="allowfullscreen"></iframe></figure> <p>Credit for this extends to a snappy script and intricate editing that bounces through its complex multiverse setting and superhero super-stakes to focus on moving character development. Thematically, it reflects on the artistic value of the superhero genre, unpacking the Spider-Man lore across its many iterations. And, of course, the visual artistry on display is mind-blowing, truly pushing cinematic excess in ways that only animation (currently) can.</p> <p>Spider-Man: Across the Spider-Verse is the kind of popular cinema that the academy is currently primed to take more seriously. It’s on track to become one of the year’s box office successes, serves a dedicated fandom, showcases a stacked cast and dynamically plays with genre and narrative conventions.</p> <p>As part two of a trilogy, it is unlikely to take out the Best Picture race altogether (Beyond the Spider-Verse, coming in 2024, is the more likely candidate if it sticks the landing). But it is still well-positioned to break through the confines of the Best Animated Feature category.<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/207716/count.gif?distributor=republish-lightbox-basic" alt="The Conversation" width="1" height="1" /></p> <p><a href="https://theconversation.com/profiles/robert-boucaut-1215760">Robert Boucaut</a>, PhD Candidate &amp; Tutor, Media Department, <em><a href="https://theconversation.com/institutions/university-of-adelaide-1119">University of Adelaide</a></em></p> <p><em>This article is republished from <a href="https://theconversation.com">The Conversation</a> under a Creative Commons license.
