Seven things to eat or avoid to lower your blood pressure

<div class="theconversation-article-body"> High blood pressure is called the silent killer. That’s because it has <a href="http://www.heart.org/HEARTORG/Conditions/HighBloodPressure/SymptomsDiagnosisMonitoringofHighBloodPressure/What-are-the-Symptoms-of-High-Blood-Pressure_UCM_301871_Article.jsp#.V7OWWI9OI2w">no symptoms</a>. Having high blood pressure (hypertension) increases your risk of heart disease, stroke, heart failure and kidney disease. Six million Australian adults (34%) have high blood pressure – 140/90 millimetres of mercury (mmHg) or more – or take medications for it. Of those, <a href="https://heartfoundation.org.au/images/uploads/publications/PRO-167_Hypertension-guideline-2016_WEB.pdf">four million have high blood pressure that isn’t treated or under control</a>. No wonder heart disease and stroke directly cost the Australian economy <a href="http://www.aihw.gov.au/WorkArea/DownloadAsset.aspx?id=60129546379">A$7.7 billion a year</a>. There is some good news. High blood pressure can be treated or prevented. Eating oats, fruit and vegetables – and beetroot, in particular – helps. So does avoiding salt, liquorice, caffeine and alcohol. Optimal blood pressure is <a href="https://theconversation.com/blood-pressure-targets-what-does-the-new-guideline-say-and-how-low-should-you-go-62684">120 mmHg or less</a> over 80 mmHg or less. Lowering it by 1-2 mmHg can have a big impact on reducing your risk of heart disease and stroke, and the nation’s health care costs. <h2>What to eat to lower your blood pressure</h2> Rolled oats A <a href="http://www.ncbi.nlm.nih.gov/pubmed/25668347">review with five research trials included</a> tested the impact of oats on systolic blood pressure (the first blood pressure number, which is the pressure at which the heart pumps blood) and diastolic blood pressure (the second number, which is when the heart relaxes) in about 400 healthy adults. The researchers found that systolic blood pressure was 2.7 mmHg lower and diastolic blood pressure was 1.5 mmHg lower when participants ate around 60 grams of rolled oats (a packed half-cup raw oats) or 25 grams of oat bran per day. This quantity of oats or oat bran contains around four grams of a type of fibre called <a href="http://www.healthline.com/health/beta-glucan-heart-healthy">beta-glucan</a>. For each extra one gram of total daily fibre, there was an extra 0.11 mmHg reduction in diastolic blood pressure. <figure class="align-right "><figcaption></figcaption></figure> Recommended <a href="https://www.nrv.gov.au/nutrients/dietary-fibre">minimum daily adult fibre intakes</a> are 30 grams for men and 25 grams for women. While some of fibre’s effect is due to weight loss, soluble fibres produce bioactive products when they’re fermented in the large bowel. These work directly to lower blood pressure. To improve your blood pressure, eat rolled oats or oat bran for breakfast, add to meat patties, or mix with breadcrumbs in recipes that call for crumbing. Beetroot Beetroot is extremely rich in a compound called inorganic nitrate. During digestion, this gets converted into nitric oxide, which causes arteries to dilate. This directly lowers the pressure in them. A <a href="http://www.ncbi.nlm.nih.gov/pubmed/23596162">review of 16 trials</a> of mostly healthy young men found drinking beetroot juice was associated with a 4.4 mmHg reduction in systolic blood pressure. But it found no change in diastolic blood pressure. However a recent <a href="http://www.ncbi.nlm.nih.gov/pubmed/25421976">trial in 68 adults</a> who already had high blood pressure found beetroot juice reduced systolic and diastolic blood pressure. <figure class="align-right "><figcaption></figcaption></figure> The men were randomly assigned to drink 250ml (one cup) of beetroot juice daily for four weeks or a non-active placebo. Blood pressure in the men who drank the beetroot juice reduced over 24 hours, with systolic blood pressure 7.7 mmHg lower and diastolic blood pressure 5.2 mmHg lower. Try wrapping whole fresh beetroot in foil and baking in the oven until soft, or grate beetroot and stir-fry with red onion and curry paste and eat as a relish. Vitamin C Vitamin C, or <a href="https://en.wikipedia.org/wiki/Vitamin_C">ascorbic acid</a>, is found in fresh vegetables and fruit. An average serve contains 10-40mg of vitamin C. In a review of 29 short-term <a href="http://www.ncbi.nlm.nih.gov/pubmed/22492364">trials of vitamin C supplements</a>, people were given 500 mg of vitamin C per day for about eight weeks. Blood pressure significantly improved, with an average reduction in systolic blood pressure of 3.84 mmHg and 1.48 mmHg for diastolic blood pressure. <figure class="align-right "><figcaption></figcaption></figure> When only those with existing high blood pressure were considered, the drop in systolic blood pressure was 4.85 mmHg. However, those <a href="http://www.ncbi.nlm.nih.gov/pubmed/26463139">at risk of kidney stones</a> need to be cautious about taking vitamin C supplements. Excess vitamin C is excreted via the kidneys and can contribute to the formation of kidney stones. One advantage of getting more vitamin C from eating more vegetables and fruit is that you boost your potassium intake, which helps <a href="http://www.bloodpressureuk.org/microsites/salt/Home/Whypotassiumhelps">counter the effects of sodium</a> from salt. <h2>What to avoid to lower your blood pressure</h2> Salt Salt or <a href="https://en.wikipedia.org/wiki/Salt">sodium chloride</a> has been used to preserve foods and as a flavour enhancer for centuries. High salt intakes are <a href="http://www.bmj.com/content/312/7041/1249?ijkey=cd4b7840cc559055a2997d90100361217218f6e8&keytype2=tf_ipsecsha">associated with higher blood pressure</a>. <figure class="align-right "><figcaption></figcaption></figure> Adults <a href="https://www.nrv.gov.au/nutrients/sodium">need between 1.2 to 2.4g of salt each day</a> (one-quarter to a half teaspoon), which is equivalent to 460 to 920mg of sodium. But in Australia seven out of ten men and three in ten women eat way more than that – and much more than the upper recommended limit of 5.9 grams of salt (about one teaspoon) or <a href="http://www.abs.gov.au/ausstats/abs@.nsf/Lookup/by%20Subject/4364.0.55.008%7E2011-12%7EMain%20Features%7ESodium%7E403">2,300 mg of sodium per day</a>. If you add salt to food yourself this pushes your sodium intake even higher. A <a href="http://www.ncbi.nlm.nih.gov/pubmed/23558162">review of studies</a> involving 3,230 people showed that reducing salt intakes by 4.4 grams a day could reduce systolic blood pressure by about 4.2 mmHg and diastolic by 2.1 mmHg. In those who had high blood pressure there were even bigger reductions of 5.4 mmHg (systolic) and 2.8 mmHg (diastolic). Avoid foods high in sodium. Don’t add salt and try to choose lower-salt versions of processed foods. Alcohol Consuming one or more alcoholic drink a day is <a href="http://www.ncbi.nlm.nih.gov/pubmed/15752957">associated with systolic blood pressure</a> that is about 2.7 mmHg and diastolic blood pressure 1.4 mmHg higher than non-drinkers. Interestingly, when you first drink an alcoholic beverage, blood pressure goes down, only to rise later. <figure class="align-right "><figcaption></figcaption></figure> A rise in blood pressure after drinking alcohol is <a href="http://www.ncbi.nlm.nih.gov/pubmed/26123682">more likely to happen when you’re awake</a>, rather during sleep. The bad news is that larger amounts of alcohol increase your risk of high blood pressure, <a href="http://www.ncbi.nlm.nih.gov/pubmed/23126352">especially in men</a>, but also to a lesser extent <a href="http://www.ncbi.nlm.nih.gov/pubmed/19804464">in women</a>. Liquorice High blood pressure due to eating black liquorice is rare, but <a href="http://www.ncbi.nlm.nih.gov/pubmed/26380428">case reports have occurred</a>. Most liquorice candy sold currently contains very little true liquorice root and therefore, little <a href="https://en.wikipedia.org/wiki/Glycyrrhizin">glycyrrhizic acid</a> (GZA), the active ingredient. <figure class="align-right "><figcaption></figcaption></figure> Occasionally, liquorice candy does contain GZA in large amounts. <a href="http://www.ncbi.nlm.nih.gov/pubmed/10944880">GZA causes sodium retention and potassium loss</a>, which contributes to high blood pressure. So check liquorice food labels. Take care if it contains liquorice root. Caffeine Caffeine is most commonly consumed in coffee, tea, cola and energy drinks. High intakes of caffeine from coffee <a href="http://www.ncbi.nlm.nih.gov/pubmed/21880846">increase blood pressure</a> in the short term. <figure class="align-right "><figcaption></figcaption></figure> In a <a href="https://www.ncbi.nlm.nih.gov/pubmed/21880846">review of five trials</a>, people given one to two cups of strong coffee had an increase in their systolic blood pressure of 8.1 mmHg and 5.7 mmHg for diastolic blood pressure, up to about three hours after drinking it. But three studies that lasted two weeks found drinking coffee did not increase blood pressure compared with decaffeinated coffee or avoiding caffeine. So you need to monitor your individual response to caffeine.<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/63940/count.gif?distributor=republish-lightbox-basic" alt="The Conversation" width="1" height="1" /> By <a href="https://theconversation.com/profiles/clare-collins-7316">Clare Collins</a>, Professor in Nutrition and Dietetics, <a href="https://theconversation.com/institutions/university-of-newcastle-1060">University of Newcastle</a>; <a href="https://theconversation.com/profiles/tracy-burrows-172931">Tracy Burrows</a>, Senior Lecturer Nutrition and Dietetics, <a href="https://theconversation.com/institutions/university-of-newcastle-1060">University of Newcastle</a>, and <a href="https://theconversation.com/profiles/tracy-schumacher-295602">Tracy Schumacher</a>, Research Associate, <a href="https://theconversation.com/institutions/university-of-newcastle-1060">University of Newcastle</a> This article is republished from <a href="https://theconversation.com">The Conversation</a> under a Creative Commons license.

What is a blood cholesterol ratio? And what should yours be?

<div class="theconversation-article-body"> Have you had a blood test to check your cholesterol level? These check the different blood fat components: <ul> <li>total cholesterol</li> <li>LDL (low-density lipoprotein), which is sometimes called “bad cholesterol”</li> <li>HDL (high-density lipoprotein), which is sometimes called “good cholesterol”</li> <li>triglycerides.</li> </ul> Your clinician then compares your test results to normal ranges – and may use ratios to compare different types of cholesterol. <iframe id="8KC9s" class="tc-infographic-datawrapper" style="border: 0;" src="https://datawrapper.dwcdn.net/8KC9s/6/" width="100%" height="400px" frameborder="0" scrolling="no"></iframe> High blood cholesterol is a major risk factor for cardiovascular disease. This is a broad term that includes disease of blood vessels throughout the body, arteries in the heart (known as coronary heart disease), heart failure, heart valve conditions, arrhythmia and stroke. So what does cholesterol do? And what does it mean to have a healthy cholesterol ratio? <h2>What are blood fats?</h2> Cholesterol is a waxy type of fat made in the liver and gut, with a small amount of pre-formed cholesterol coming from food. Cholesterol is found in all cell membranes, contributing to their structure and function. Your body <a href="https://www.ncbi.nlm.nih.gov/books/NBK513326/">uses cholesterol to make</a> vitamin D, bile acid, and hormones, including oestrogen, testosterone, cortisol and aldosterone. When there is too much cholesterol in your blood, it gets deposited into artery walls, making them hard and narrow. This process is called <a href="https://en.wikipedia.org/wiki/Atherosclerosis">atherosclerosis</a>. Cholesterol is <a href="https://www.ncbi.nlm.nih.gov/books/NBK513326/">packaged with</a> <a href="https://en.wikipedia.org/wiki/Triglyceride">triglycerides</a> (the most common type of fat in the body) and specific <a href="https://en.wikipedia.org/wiki/Apolipoprotein">“apo” proteins</a> into “lipo-proteins” as a package called “very-low-density” lipoproteins (VLDLs). These are transported via the blood to body tissue in a form called low-density lipoprotein (LDL) cholesterol. Excess cholesterol can be transported back to the liver by high-density lipoprotein, the HDL, for removal from circulation. Another less talked about blood fat is Lipoprotein-a, or Lp(a). This is determined by your genetics and <a href="https://www.victorchang.edu.au/heart-disease/high-cholesterol">not influenced by lifestyle factors</a>. About one in five (<a href="https://www1.racgp.org.au/ajgp/2021/may/lipid-management-and-implications-for-australian-g">20%</a>) of Australians are carriers. Having a high Lp(a) level is an independent cardiovascular disease risk factor. <h2>Knowing your numbers</h2> Your blood fat levels <a href="https://www.heartfoundation.org.au/your-heart/high-blood-cholesterol">are affected by</a> both modifiable factors: <ul> <li>dietary intake</li> <li>physical activity</li> <li>alcohol</li> <li>smoking</li> <li>weight status.</li> </ul> And non-modifiable factors: <ul> <li>age</li> <li>sex</li> <li>family history.</li> </ul> <iframe id="S7Xp4" class="tc-infographic-datawrapper" style="border: 0;" src="https://datawrapper.dwcdn.net/S7Xp4/1/" width="100%" height="400px" frameborder="0" scrolling="no"></iframe> <h2>What are cholesterol ratios?</h2> Cholesterol ratios are sometimes used to provide more detail on the balance between different types of blood fats and to evaluate risk of developing heart disease. Commonly used ratios include: <h2>1. Total cholesterol to HDL ratio</h2> This ratio is used in Australia to <a href="https://www.cvdcheck.org.au/calculator">assess risk of heart disease</a>. It’s calculated by dividing your total cholesterol number by your HDL (good) cholesterol number. A higher ratio (<a href="https://www.medicalnewstoday.com/articles/cholesterol-ratio-calculator#how-to-calculate">greater than 5</a>) is associated with a higher risk of heart disease, whereas a lower ratio is associated with a lower risk of heart disease. A <a href="https://pubmed.ncbi.nlm.nih.gov/36589799/">study</a> of 32,000 Americans over eight years found adults who had either very high, or very low, total cholesterol/HDL ratios were at 26% and 18% greater risk of death from any cause during the study period. Those with a ratio of greater than 4.2 had a 13% higher risk of death from heart disease than those with a ratio lower than 4.2. <h2>2. Non-HDL cholesterol to HDL cholesterol ratio (NHHR)</h2> Non-HDL cholesterol is the total cholesterol minus HDL. Non-HDL cholesterol includes all blood fats such as LDL, triglycerides, Lp(a) and others. This ratio is abbreviated as NHHR. This ratio has been used more recently because it compares the ratio of “bad” blood fats that can contribute to atherosclerosis (hardening and narrowing of the arteries) to “good” or anti-atherogenic blood fats (HDL). Non-HDL cholesterol is a <a href="https://pubmed.ncbi.nlm.nih.gov/31170997/">stronger predictor of cardiovascular disease risk</a> than LDL alone, while <a href="https://pubmed.ncbi.nlm.nih.gov/37228232/">HDL is associated with</a> lower cardiovascular disease risk. Because this ratio removes the “good” cholesterol from the non-HDL part of the ratio, it is not penalising those people who have really high amounts of “good” HDL that make up their total cholesterol, which the first ratio does. Research has suggested this ratio may be a stronger <a href="https://pubmed.ncbi.nlm.nih.gov/39949279/">predictor of atherosclerosis in women than men</a>, however more research is needed. Another <a href="https://pubmed.ncbi.nlm.nih.gov/39415313">study</a> followed more than 10,000 adults with type 2 diabetes from the United States and Canada for about five years. The researchers found that for each unit increase in the ratio, there was around a 12% increased risk of having a heart attack, stroke or death. They identified a risk threshold of 6.28 or above, after adjusting for other risk factors. Anyone with a ratio greater than this is at very high risk and would require management to lower their risk of heart disease. <h2>3. LDL-to-HDL cholesterol ratio</h2> LDL/HDL is calculated by dividing your LDL cholesterol number by the HDL number. This gives a ratio of “bad” to “good” cholesterol. A lower ratio (<a href="https://www.medicalnewstoday.com/articles/cholesterol-ratio-calculator#how-to-calculate">ideal is less than 2.0</a>) is associated with a lower risk of heart disease. While there is lesser focus on LDL/HDL, these ratios have been shown to be predictors of occurrence and <a href="https://pubmed.ncbi.nlm.nih.gov/35843962/">severity of heart attacks</a> in patients presenting with chest pain. If you’re worried about your cholesterol levels or cardiovascular disease risk factors and are aged 45 and over (or over 30 for First Nations people), consider seeing your GP for a Medicare-rebated <a href="https://www.heartfoundation.org.au/your-heart/heart-health-checks">Heart Health Check</a>.<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/253126/count.gif?distributor=republish-lightbox-basic" alt="The Conversation" width="1" height="1" /> By <a href="https://theconversation.com/profiles/clare-collins-7316">Clare Collins</a>, Laureate Professor in Nutrition and Dietetics, <a href="https://theconversation.com/institutions/university-of-newcastle-1060">University of Newcastle</a> and <a href="https://theconversation.com/profiles/erin-clarke-1314081">Erin Clarke</a>, Postdoctoral Researcher, Nutrition and Dietetics, <a href="https://theconversation.com/institutions/university-of-newcastle-1060">University of Newcastle</a> This article is republished from <a href="https://theconversation.com">The Conversation</a> under a Creative Commons license.

"It makes my blood boil": Today reporter fires up over athletes' pay

Sports reporter and Today presenter Roz Kelly has fired up over a list revealing the highest paid athletes in 2024 for one major reason. <a href="https://www.sportico.com/feature/highest-paid-athletes-in-the-world-1234765608/" target="_blank" rel="noopener">Sportico</a> revealed the list on Friday, which features one concerning theme that caught Kelly's attention: not a single female athlete features in the top 100 list. The salary figures for each athlete combine their reported annual salary as well as endorsement deals that are often worth millions. The lucrative list is topped by football icon Cristiano Ronaldo, who reportedly pocketed $411 million in 2024. "It makes my blood boil, it makes me so, so angry," Kelly said. "It's just proof of the gender pay gap in sport." "Some of these women are some of the most marketable in the world right now, they are on billboards everywhere." "I know like tennis players and surfers, they have equal prize money. There's still a long way to go in cricket, and soccer... I'm on a rant now." "When it comes to endorsement deals they are severely underpaid compared to their male counterparts." Five of the top 10 paid athletes in 2024 were football players, while basketball, golf, and American football also feature heavily in the top 20. Ben Simmons is the lone Aussie athlete in the top 100 after he earned $65m last year, coming in at 85th on the list.

Parents of Laos poisoning victims speak out

Melbourne teenagers Bianca Jones and Holly Bowles, were on a the trip of a lifetime backpacking through Southeast Asia on their gap year when they fell seriously ill. The 19-year-old friends were staying at the popular Nana Backpacker Hostel in Vang Vieng last November, when they were rushed to hospital after a night out with suspected <a href="https://www.oversixty.com.au/travel/travel-trouble/two-aussie-teens-poisoned-in-laos-identified" target="_blank" rel="noopener">methanol poisoning</a>. The teens were among six tourists who died in the mass poisoning. The backpacker hostel has since shut down, and while the Laos government said it was "profoundly saddened" by the deaths and vowed to prosecute those responsible, months later, the girls' families are still searching for answers. In an exclusive interview with 60 Minutes journalist Tara Brown, their parents – Mark and Michelle Jones alongside Sam and Shaun Bowles – said the Laos government has refused to meet with them since the teenagers’ deaths. “We’ve heard nothing,” Mark said in the interview on Sunday. "For them not to reach out is, that's just not good enough." When it came to the Laos government's response, both families felt there was a lack of empathy and accountability. After the backpacker hostel was shut down and eight staff were <a href="https://www.oversixty.com.au/finance/legal/eight-people-detained-over-laos-methanol-poisoning" target="_blank" rel="noopener">detained and released</a>, the investigation has seemingly stalled. "It seems like a complete cover-up," Mark said, claiming there was a lack of transparency in the investigation. "We haven't heard anything from the Laos government. Not a thing," Shaun added. "It's appalling." "The Laos government sent their condolences via the federal police, and that to us means nothing, nothing at all," Shaun continued. The parents hope that by speaking out about the dangers of methanol poisoning, others will be able to avoid suffering similar tragedies in their own families. “I cannot have my daughter’s passing not mean anything," Mark said. "If this gets parents to have a conversation with their kids if they're off travelling, then that's something," Shaun added. All four parents said they had no confidence the truth could ever be revealed, but they still want justice and answers. "We want some form of closure," Mark said. "We want to understand that people who have done wrong by our daughter and Holly and the other people are going to be brought to justice." Images: Nine/ 60 Minutes

Novak Djokovic "poisoned" in Australia

Novak Djokovic claims he was "poisoned" while he was detained in a Melbourne hotel room ahead of the 2022 Australian Open. The Serbian tennis champion was infamously deported from the country three years ago when he did not meet the country’s COVID-19 vaccination requirements at the height of the pandemic. After the federal government cancelled his visa, he stayed at a Melbourne immigration detention facility for five days alongside refugees and asylum seekers. During his time at the Park Hotel in Carlton, he claims he was fed food that was "poisoned" with “lead and mercury”, as he faced "some health issues" when he returned to Serbia. “I had some health issues. And I realised that in that hotel in Melbourne I was fed with some food that poisoned me,” Djokovic told <a href="https://www.gq.com/story/novak-djokovic-conquered-tennis-whats-next" target="_blank" rel="noopener">GQ Sports</a>. “I had some discoveries when I came back to Serbia. I never told this to anybody publicly, but discoveries that I had a really high level of heavy metal. Heavy metal. I had the lead, very high level of lead and mercury.” Pressed on whether he thought the substances entered his body via the food in Melbourne, Djokovic said: “That’s the only way." “Yeah, (I was) very sick. It was like the flu, just a simple flu. But when it was days after that a simple flu took me down so much, I had an emergency medical team treat me at home. I had that several times and then I had to do toxicology (tests).” The 37-year-old, who has claimed the Aus Open victory 10 times, says he holds no grudges against Australia, but he can’t say the same thing for his family. “Well, for my wife and my parents and my family, it’s not (water under the bridge),” he says. “For me, it is. For me, I’m fine. I never held any grudge over Australian people. In contrary, actually, a lot of Australian people that I meet, I met in Australia the last few years or elsewhere in the world, coming up to me and apologising to me for the treatment I received because they were embarrassed by their own government at that point." “I actually love being there, and I think my results are a testament to my sensation of playing tennis and just being in that country.” Image credits: Shutterstock

12 dead in mass poisoning at ski resort

The bodies of 12 people have been found dead in a luxury ski resort in Georgia after a suspected carbon monoxide poisoning. The bodies of 11 Indian nationals and one Georgian national were discovered on Saturday at a ski resort in Gudauri, in the north of the Caucasus country, according to local police. Authorities confirmed that “preliminary tests do not indicate any trace of violence on the bodies,” which were found on the second floor of a building housing an Indian food restaurant at the ski resort. “An oil-powered generator was turned on after the building lost electricity” on Friday, police said, which is believed to be the source of the poisoning. The identities of the victims were not immediately released but they are presumed to be employees of the restaurant, according to the Georgian Interior Ministry. The deaths are being treated as negligent manslaughter, as autopsies have been ordered to determine the actual cause of death, while authorities have opened an investigation into the incident. The Indian Embassy in Georgia's capital of Tbilisi said it was "committed to providing all possible support" to the bereaved families and that it was working to repatriate the bodies of the 11 Indian nationals. Gudauri, lodged high up in the Caucasus Mountains close to the border with Russia, is becoming increasingly popular with tourists, offering a cheaper alternative to Europe's main resorts in the Alps.

Four Australians hospitalised after suspected poisoning in Fiji

A resort in Fiji is investigating a suspected poisoning that has left at least four Australians hospitalised. Local health officials reported that seven guests of the Warwick Fiji Resort were taken to hospital after allegedly drinking cocktails that had been poisoned. The seven people were aged from 18 to 56 and had nausea, vomiting, and neurological symptoms after consuming the alcoholic beverages. According to the ABC, four Australian women aged 56, 49, 19 and 18 were among those receiving treatment in hospital. The 56-year-old was under constant surveillance in hospital, the public broadcaster said, while the 49-year-old and 18-year-old were critical but last night not as serious. A Warwick Fiji Resort spokesperson confirmed they were aware of the "recent news regarding suspected alcohol poisoning" and are taking the matter "very seriously". "Please rest assured that we are taking this matter very seriously and are currently conducting a thorough investigation," a spokesperson told <a href="https://www.9news.com.au/world/fiji-drink-poisoning-fears-two-australians-believed-among-seven-hospitalised/86aa947d-c1b6-475d-a57d-f22d8edf2e1f" target="_blank" rel="noopener">9news.com.au</a>. "We are also awaiting the health authorities test result report to gather all necessary information. "At this moment, we do not have conclusive details, but we are committed to ensuring the safety and well-being of our guests. We will keep you updated as more information becomes available." The Australian government <a title="Smart Traveller" href="https://www.smartraveller.gov.au/destinations/pacific/fiji" target="_blank" rel="noopener">Smart Traveller</a> website updated its safety alert for Fiji yesterday, warning travellers to "be alert to the potential risks around drink spiking and methanol poisoning through consuming alcoholic drinks".

Melbourne teen poisoned in Laos farewelled

Melbourne teenager Holly Morton-Bowles has been farewelled in an emotional funeral service. Grieving friends and family gathered at Beaumaris Secondary College on Monday to honour the 19-year-old, who died alongside her friend after being poisoned in Laos. Holly and Bianca Jones were among six people who drank methanol-laced cocktails in the town of Vang Vieng in Laos in November while on a gap year holiday. Beaumaris Secondary College Acting Principal Peter Bartlett read a statement on behalf of Morton-Bowles' parents Shaun and Samantha, and brother James. "We would like to thank the people of Australia, Canada and the rest of the world for the outpouring of love, support, and compassion during this extremely difficult time," Bartlett said. "Your kindness has been a source of strength and comfort for our family." "Today is a profoundly significant day for our family as we come together to celebrate Holly's life and spirit. Holly was loved and adored by so many people, and today is a reflection on her life, however she will remain forever in our hearts." "We would like to thank all those that have helped in the preparation of today. We kindly ask that our family be given the space to grieve privately on this deeply emotional day." "This is the most difficult time of our lives, and we thank you for respecting our privacy." The families of both Morton-Bowles and Jones have asked people to donate to the girls' GoFundMe in lieu of flowers. Bianca Jones was farewelled on Friday at Mentone Girl's Grammar, in Mentone, the same school she had graduated from last year, with principal Natalie Charles reading out a statement from the Jones family, thanking the public for their "outpouring of love, support and compassion".

Many people don’t measure their blood pressure properly at home – here’s how to get accurate readings

<div class="theconversation-article-body"><a href="https://theconversation.com/profiles/niamh-chapman-2262829">Niamh Chapman</a>, <a href="https://theconversation.com/institutions/university-of-sydney-841">University of Sydney</a>; <a href="https://theconversation.com/profiles/dean-picone-2264237">Dean Picone</a>, <a href="https://theconversation.com/institutions/university-of-sydney-841">University of Sydney</a>, and <a href="https://theconversation.com/profiles/eleanor-clapham-2264235">Eleanor Clapham</a>, <a href="https://theconversation.com/institutions/university-of-tasmania-888">University of Tasmania</a> Measuring your blood pressure at home means you can take readings over several days to get a better picture of your health, instead of one-off measurements at the doctor’s clinic. It’s important you follow specific steps to get an accurate reading. But <a href="https://www.ahajournals.org/doi/10.1161/HYPERTENSIONAHA.124.23678">our study</a> found most Australians do not measure their blood pressure correctly at home and very few were told the steps to follow. We have created <a href="https://bloodpressuretoolkit.com/">resources</a> to help people measure their blood pressure at home, understand their readings and take action with their health-care team. <h2>High blood pressure is a big issue</h2> High blood pressure is a major health problem in Australia and globally. <a href="https://onlinelibrary.wiley.com/doi/full/10.5694/mja2.51350">One in three Australian adults</a> have high blood pressure, also called hypertension. This is when your <a href="https://www.heartfoundation.org.au/your-heart/blood-pressure-and-your-heart">blood pressure</a> is <a href="https://www.ahajournals.org/doi/10.1161/HYPERTENSIONAHA.120.15026">at or above 140/90mmHg</a> (mmHg refers to millimetres of mercury, a standard measurement of blood pressure). High blood pressure is the <a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC10881002/">leading contributor</a> to preventable health issues and early death among Australians because it is the main risk factor for heart disease, stroke, dementia and kidney disease. <h2>Why measuring blood pressure is important</h2> High blood pressure often has no symptoms. So the only way to know if you have it is to measure it. You may also need to check if your blood pressure has lowered after starting medication or if you’re making changes to your lifestyle, such as doing more exercise, giving up smoking or reducing salt intake. Low blood pressure (<a href="https://www.betterhealth.vic.gov.au/health/conditionsandtreatments/blood-pressure-low-hypotension">hypotension</a>) can also be an issue. But blood pressure changes based on how we are feeling, what we’ve eaten or the activities we have just been doing. These normal responses mean our blood pressure can change from minute to minute and hour to hour. This is why there are specific, recommended steps to follow to reliably measure your blood pressure and to be able to compare readings taken days, months and years apart. <hr /> <iframe id="lBVm6" class="tc-infographic-datawrapper" style="border: 0;" src="https://datawrapper.dwcdn.net/lBVm6/" width="100%" height="400px" frameborder="0" scrolling="no"></iframe> <hr /> <h2>Mistakes are common</h2> We surveyed and interviewed 350 people (who were all measuring their blood pressure at home) from around Australia to find out how Australians measure blood pressure at home and if they receive any education to help them know what to do. Our study found no one followed all of the specific, recommended steps to measure their blood pressure. Instead they said they measured their blood pressure at different times of the day after doing different things. We found most people measured their blood pressure while sitting down (90%) and with the cuff on their bare arm (77%), which is the right thing to do. While 58% of people took two blood pressure measures each time, which is correct, only 40% used the average of the two blood pressure readings. Very few (15%) measured their blood pressure over several days in both the morning and evening. Only half of the people in our study used a blood pressure device that had been <a href="https://bloodpressuretoolkit.com/what_device_should_i_use">clinically validated</a>. This means the device has been <a href="https://www.ahajournals.org/doi/10.1161/HYPERTENSIONAHA.117.10237">tested for accuracy</a> by the manufacturer according to <a href="https://www.iso.org/sectors/health">international standards</a>, not just safety. <h2>Consultation and communication</h2> Regardless of whether or not a doctor had recommended they measure their blood pressure at home, most people (78%) reported their blood pressure readings to their doctor. These findings tell us doctors often use home blood pressure readings to help diagnose and manage high blood pressure. This emphasises how important it is to ensure people measure blood pressure correctly. Many people were measuring their blood pressure a few times a week or month. But most <a href="https://pmc.ncbi.nlm.nih.gov/articles/PMC4671913/">guidelines</a> recommend blood pressure only needs to be measured at home: every day over a week, every six months; and ideally before you see your doctor and after you start or change blood pressure medication. Measuring blood pressure at home can bring peace of mind, which many study participants described. But measuring your blood pressure too often may create unnecessary stress, potentially leading to higher blood pressure readings. Instead, it’s better to agree with your doctor how often you should measure your blood pressure and to follow the recommended steps each time to make sure your readings are as accurate and useful as possible. <h2>Support for blood pressure measurement</h2> We found few people had received any education or guidance from health-care professionals about how to measure their blood pressure at home. Instead, many study participants looked for information online to help them know what their blood pressure numbers meant and changes they could make to lower their blood pressure. They were less interested in learning how to measure accurately. So we have worked with people who measure and manage their blood pressure at home to create a <a href="https://bloodpressuretoolkit.com/">simple guide</a> to help you choose a blood pressure device, measure your blood pressure accurately, understand your blood pressure readings and take action to control your blood pressure. <hr /> For more information about managing your blood pressure at home, <a href="https://bloodpressuretoolkit.com/">see our resources</a>. You can also check if your blood pressure device has been <a href="https://bloodpressuretoolkit.com/what_device_should_i_use">tested for accuracy</a>.<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/244161/count.gif?distributor=republish-lightbox-basic" alt="The Conversation" width="1" height="1" /> <a href="https://theconversation.com/profiles/niamh-chapman-2262829">Niamh Chapman</a>, Senior Research Fellow, Hypertension and Patient Engagement, <a href="https://theconversation.com/institutions/university-of-sydney-841">University of Sydney</a>; <a href="https://theconversation.com/profiles/dean-picone-2264237">Dean Picone</a>, Senior Research Fellow, Sydney School of Health Sciences, Faculty of Medicine and Health, <a href="https://theconversation.com/institutions/university-of-sydney-841">University of Sydney</a>, and <a href="https://theconversation.com/profiles/eleanor-clapham-2264235">Eleanor Clapham</a>, PhD candidate, School of Health and Medicine, <a href="https://theconversation.com/institutions/university-of-tasmania-888">University of Tasmania</a> Image credits: Shutterstock This article is republished from <a href="https://theconversation.com">The Conversation</a> under a Creative Commons license.

Eight people detained over Laos methanol poisoning

Eight men have been detained over the suspected mass methanol poisoning in Laos that killed six tourists, including two Australians. Police in Laos told the <a href="https://www.abc.net.au/news/2024-11-26/laos-methanol-poisoning-detained/104650642" target="_blank" rel="noopener">ABC</a> that detained men were staff and management of the Nana Backpackers hostel, where Melbourne teenagers Bianca Jones and Holly Bowles were staying when they fell sick. The two 19 year olds had consumed the alcoholic beverages in the party town of Vang Vieng, and later died in seperate hospitals in Thailand. Four other tourists from Denmark, the UK and the US have also died. Police in Laos last week forcibly shut down the Nana hostel, where five of the six victims who died were staying. They questioned staff, ranging in ages from 23 to 47, including the bartender and owner, while the Laos government vowed to bring the perpetrators to justice. The arrests come as the bodies of Bianca Jones and Holly Bowles arrived home in Australia on Tuesday night, with Bianca's father Mark fronting the media at Melbourne Airport to welcome the news of the arrests. "We want to grieve. We miss our daughters desperately. I was happy to hear there's been some movement over in Laos," he said. "I would continue to urge our government to continue to pursue whomever. We will make every effort we can to help raise awareness of methanol poisoning." Image credits: RUNGROJ YONGRIT/EPA-EFE/Shutterstock

Foreign victims killed in mass methanol poisoning identified

The victims of the mass methanol poisoning in Laos have been identified, with the death toll now rising to six. Danish women Anne-Sofie Orkild Coyman, 20, Freja Vennervald Sorensen, 21, and American man James Louis Hutson, 57, were among those who died after a group of backpackers consumed alcoholic drinks spiked with methanol in the party town of Vang Vieng. Bianca Jones and Holly Bowles, both 19, had already been named as two Melbourne teenagers who lost their lives last week while on their gap year, along with British woman Simone White, 28. Ms Jones and Ms Bowles were staying at Nana Backpackers Hostel, which has been closed since November 14th, just days after the incident occurred. It is understood that the two Danish and American victims were also staying at Nana Backpackers Hostel. Ms Coyman and Ms Sorensen were reportedly found unconscious on the bathroom floor on November 13th after they had been out drinking the night before. Mr Hutson was reportedly found unconscious in his bed on November 13th after staff noticed he had not come out of his room. All three tourists died in the following days in hospital. Dr Yaher, who first treated Ms Bowles in Vang Vieng, claimed she went from a state of confusion to a coma in just half an hour after consuming the methanol-laced beverage. The doctor told The Times she was confused and fatigued, and didn’t know what had happened when she arrived at his small one-storey hospital at 2am. “We treated her symptomatically,” he told the publication. “We put her on an IV drip and gave her vitamins. But after 30 minutes she had a seizure and went into a coma. I was so surprised. We gave her CPR, because she had difficulty breathing, and we intubated her and referred her to Vientiane.” The Laos government released a statement on Saturday expressing sympathy and condolences to the families of the tourists who died, saying an investigation was underway and promised to “bring the perpetrators to justice according to the law”.

Father's emotional plea after death of his daughter from methanol poisoning

The grieving father of 19-year-old Bianca Jones, who tragically died after consuming methanol-laced cocktails in Laos, has issued a plea to ensure his daughter’s death was not in vain. Bianca and her friend Holly Bowles had been travelling around south-east Asia on a gap year trip when they consumed the deadly drinks in the party town of Vang Vieng, a popular tourist area about 130km north of Laos capital, Vientiane. Both Bianca and Holly were rushed to seperate hospitals in Thailand, and passed away last week. Speaking publicly for the first time about the tragedy, Bianca’s father Mark Jones, said his daughter’s “lust for life and adventure” had “cruelly been cut short”. “Our daughter was on the trip of a lifetime with one of her best mates,” he said. “This was meant to be a trip full of lifelong memories, and was to be the first of many. Bianca wanted to explore the world, meet new friends, lead and create change for good.” Following the deaths of the two young women, an outpouring of sympathy flooded in from around Australia including from Prime Minister Anthony Albanese, while hundreds attended a vigil held in the women’s honour in Melbourne on Saturday. Mr Jones thanked Australian government for its support but made a plea to authorities in Laos. “I would like to take this opportunity to urge the Laos government to investigate this to the fullest extent, to make sure this incident doesn’t happen again,” he said. “We can’t have the passing of our daughter … not lead to change to protect others. Young men and women should be able to travel, create their own life experiences and be safe." “We’ll forever miss our beautiful girl and hope her loss of life has not been in vain.” The Laotian government has promised to bring perpetrators to justice after the mass poisoning that has killed six tourists, including the two Australian women.

What is methanol? How does it get into drinks and cause harm?

<div class="theconversation-article-body"><a href="https://theconversation.com/profiles/ian-musgrave-1808">Ian Musgrave</a>, <a href="https://theconversation.com/institutions/university-of-adelaide-1119">University of Adelaide</a> Melbourne teenager Bianca Jones <a href="https://www.abc.net.au/news/2024-11-21/bianca-jones-dead-laos-methanol-poisoning/104630384">has died</a> and her friend Holly Bowles remains severely ill in hospital in Thailand, after experiencing suspected methanol poisoning while they were travelling in Laos. The pair are reportedly among <a href="https://x.com/Smartraveller/status/1858850858227954118">several foreign nationals</a> who became ill after unknowingly consuming alcoholic drinks containing methanol in the south-east Asian country. So what is methanol, and how does it make people sick? <h2>Methanol versus ethanol</h2> <a href="https://en.wikipedia.org/wiki/Methanol">Methanol</a> is an <a href="https://en.wikipedia.org/wiki/Alcohol_(chemistry)">alcohol</a>, like the familiar <a href="https://en.wikipedia.org/wiki/Ethanol">ethanol</a> we consume in alcoholic beverages. Like ethanol, methanol is a colourless, flammable liquid. It has a smell similar to ethanol as well. But the two have different chemical structures. Methanol is composed of only one carbon atom, while ethanol has two. <figure class="align-center "><img src="https://images.theconversation.com/files/633188/original/file-20241120-15-i7wr12.png?ixlib=rb-4.1.0&q=45&auto=format&w=754&fit=clip" sizes="(min-width: 1466px) 754px, (max-width: 599px) 100vw, (min-width: 600px) 600px, 237px" srcset="https://images.theconversation.com/files/633188/original/file-20241120-15-i7wr12.png?ixlib=rb-4.1.0&q=45&auto=format&w=600&h=300&fit=crop&dpr=1 600w, https://images.theconversation.com/files/633188/original/file-20241120-15-i7wr12.png?ixlib=rb-4.1.0&q=30&auto=format&w=600&h=300&fit=crop&dpr=2 1200w, https://images.theconversation.com/files/633188/original/file-20241120-15-i7wr12.png?ixlib=rb-4.1.0&q=15&auto=format&w=600&h=300&fit=crop&dpr=3 1800w, https://images.theconversation.com/files/633188/original/file-20241120-15-i7wr12.png?ixlib=rb-4.1.0&q=45&auto=format&w=754&h=377&fit=crop&dpr=1 754w, https://images.theconversation.com/files/633188/original/file-20241120-15-i7wr12.png?ixlib=rb-4.1.0&q=30&auto=format&w=754&h=377&fit=crop&dpr=2 1508w, https://images.theconversation.com/files/633188/original/file-20241120-15-i7wr12.png?ixlib=rb-4.1.0&q=15&auto=format&w=754&h=377&fit=crop&dpr=3 2262w" alt="Models of methanol and ethanol depicted with balls and sticks." /><figcaption>Methanol (left) and ethanol (right) have differing chemical structures. Wikimedia Commons, <a class="license" href="http://creativecommons.org/licenses/by/4.0/">CC BY</a></figcaption></figure> That one carbon atom makes all the difference. It means methanol is processed differently in our bodies and is much more toxic than ethanol. Methanol is used in a <a href="https://pubchem.ncbi.nlm.nih.gov/compound/Methanol">variety of industrial and household products</a>, such as windshield cleaning fluids, antifreeze and fuel. It’s not safe for human consumption. <h2>What makes methanol toxic?</h2> The difference is in how methanol is metabolised, or broken down in our bodies. Ethanol is metabolised into a chemical compound called acetaldehyde. Acetaldehyde is toxic, but is rapidly converted to acetate (also known as acetic acid, found in vinegar). Generating an acid may sound bad, but acetate actually <a href="https://pmc.ncbi.nlm.nih.gov/articles/PMC6699882/">produces energy and makes important molecules</a> in the body. By contrast, methanol is metabolised into <a href="https://www.cancer.gov/about-cancer/causes-prevention/risk/substances/formaldehyde">formaldehyde</a> (a chemical used in <a href="https://www.safework.nsw.gov.au/hazards-a-z/hazardous-chemical/priority-chemicals/formaldehyde">industrial glues</a> and for embalming corpses, for example) and then to <a href="https://pubchem.ncbi.nlm.nih.gov/compound/Formic-Acid">formic acid</a> (the chemical in some ant bites that makes them hurt so much). Unlike acetate, which the body uses, formic acid <a href="https://pubmed.ncbi.nlm.nih.gov/1665561/">poisons the mitochondria</a>, the powerhouses of the cells. As a result, a person exposed to methanol can go into severe <a href="https://www.ncbi.nlm.nih.gov/books/NBK482121/">metabolic acidosis</a>, which is when too much acid builds up in the body. Methanol poisoning can cause nausea, vomiting, and abdominal pain. The acidosis then causes depression of the central nervous system which can cause people with methanol poisoning to fall unconscious and go into a coma, as well as retinal damage leading to vision loss. This is because the retinas are full of active mitochondria and sensitive to them being damaged. Death is not inevitable if only a small amount of methanol has been consumed, and rapid treatment will greatly reduce damage. However, permanent vision damage can occur even at <a href="https://www.ncbi.nlm.nih.gov/books/NBK482121/">non-lethal doses</a> if treatment is not administered quickly. <h2>What does treatment involve?</h2> <a href="https://www.ncbi.nlm.nih.gov/books/NBK482121/">Treatment</a> is mainly supportive care, such as intubation and mechanical ventilation to help the patient to breathe. But it can also involve drugs such as <a href="https://go.drugbank.com/drugs/DB01213">fomepizole</a> (which inhibits the generation of toxic formic acid) and dialysis to remove methanol and its metabolites from the body. <h2>How does methanol get into alcoholic drinks?</h2> Methanol can turn up in any alcoholic beverage, but it’s most likely in beverages with higher alcohol content, such as spirits, and traditionally brewed drinks, such as fruit wines. Methanol can get into alcoholic beverages in a number of ways. Sometimes it’s added <a href="https://pmc.ncbi.nlm.nih.gov/articles/PMC8303512/">deliberately and illegally</a> during or after manufacturing as a cheaper way to increase the alcohol content in a drink. <a href="https://pmc.ncbi.nlm.nih.gov/articles/PMC5028366/">Traditional brewing methods</a> can also inadvertently generate methanol as well as ethanol and produce toxic levels of methanol depending on the microbes and the types of plant materials used in the fermentation process. We don’t yet know how the Australian teenagers came to be poisoned in this tragedy. But it is a good idea when travelling (particularly in areas with traditionally fremented drinks, such as south-east Asia, the Indian subcontinent and parts of Africa) to always be careful. The Australian government’s <a href="https://www.smartraveller.gov.au/before-you-go/safety/partying#methanol">Smartraveller website</a> advises that to avoid methanol poisoning you should be careful drinking cocktails and drinks made with spirits, drink only at reputable licensed premises and avoid home-made alcoholic drinks. Drinking only mass-produced commercial brews can be safer, though understandably people often want to try locally made drinks as part of their adventure.<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/244151/count.gif?distributor=republish-lightbox-basic" alt="The Conversation" width="1" height="1" /> <a href="https://theconversation.com/profiles/ian-musgrave-1808">Ian Musgrave</a>, Senior lecturer in Pharmacology, <a href="https://theconversation.com/institutions/university-of-adelaide-1119">University of Adelaide</a> Image credits: Shutterstock This article is republished from <a href="https://theconversation.com">The Conversation</a> under a Creative Commons license.

Fifth death confirmed in Laos poisoning

A young British lawyer has died in hospital after a suspected mass poisoning that has claimed the lives of four others. On Thursday, Melbourne teen Bianca Jones became the fourth person to die from suspected methanol poisoning following the deaths of two Danish women and an American who had all been holidaying in the in the party town of Vang Vieng. Lawyer Simone White, 28, was among a dozen other tourists taken to hospital after visiting the backpacker town, with Thai police confirming her death on Friday morning. In a statement to <a href="https://7news.com.au/news/british-lawyer-simone-white-in-hospital-after-apparent-mass-methanol-poisoning-in-laos-c-16833986" target="_blank" rel="noopener">7News</a>, a spokesperson for Britain’s Foreign, Commonwealth and Development Office confirmed a death in Laos, saying, “We are supporting the family of a British woman who has died in Laos, and we are in contact with the local authorities.” Her friend Bethany Clarke, who was with White on holiday, urged tourists in the region to “avoid all local spirits” after their group of six fell ill. “Our group stayed in Vang Vieng and we drank free shots offered by one of the bars. Just avoid them as so not worth it,” she wrote in a Laos backpacking Facebook group. “Six of us who drank from the same place are in hospital currently with methanol poisoning.” Australian Prime Minister Anthony Albanese paid tribute to Jones, 19, in federal parliament on Thursday after news of her death was shared, as her friend Holly Bowles continues to fight for her life in a Bangkok hospital. “This is every parent’s very worst fear and a nightmare that no one should have to endure,” Albanese said.

"Every parent's nightmare": Families of poisoned teens share update

The families of Holly Bowles and Bianca Jones have shared a heartbreaking update as the teenagers continue to fight for their lives after being <a href="https://oversixty.com.au/travel/travel-trouble/two-aussie-teens-poisoned-in-laos-identified" target="_blank" rel="noopener">poisoned</a> in Laos. While travelling around south-east Asia on a gap year, the Melbourne 19 year olds consumed what is believed to be methanol-laced drinks in Laos. The young women were found barely alive in their hotel room and were rushed to a hospital in the neighbouring country of Thailand, where they remain on life support. Holly’s dad Shaun Bowles fronted the media on Wednesday in Bangkok where he confirmed his daughter remained in the ICU in a critical condition, where the family are spending as much time as possible by her bedside. “Right now our daughter remains in the intensive care unit in a critical condition. She’s on life support,” Shaun said. “We’d just like to thank everyone from back home for all the support and love that we’re receiving but we’d also like for people to appreciate right now we just need privacy so we can spend as much time as we can with Holly.” Bianca's family also released a statement saying there was no update on her condition, but confirmed that she remains on life support. "Our family has been overwhelmed by the messages of love and support that have come from across Australia," the statement from the family reads. "This is every parent's nightmare and we want to ensure no other family is forced to endure the anguish we are going through. We hope the authorities can get to the bottom of what happened as soon as possible." Authorities suspect the girls drank poisoned cocktails which reportedly had shots of "vodka" while holidaying in the party town of Vang Vieng, a popular tourist area about 130km north of Laos capital, Vientiane. They were among a large group of international travellers who fell victim to what is feared to be a mass poisoning which has already killed two other people. Editor's note: Police in Thailand confirmed the death of Bianca Jones on Thursday afternoon. Holly Bowles is understood to still be in hospital. Image credits: Facebook

From eye exams to blood tests and surgery: how doctors use light to diagnose disease

<div class="theconversation-article-body"><a href="https://theconversation.com/profiles/matthew-griffith-1539353">Matthew Griffith</a>, <a href="https://theconversation.com/institutions/university-of-south-australia-1180">University of South Australia</a> You’re not feeling well. You’ve had a pounding headache all week, dizzy spells and have vomited up your past few meals. You visit your GP to get some answers and sit while they shine a light in your eyes, order a blood test and request some medical imaging. Everything your GP just did relies on light. These are just some of the optical technologies that have had an enormous impact in how we diagnose disease. <h2>1. On-the-spot tests</h2> Point-of-care diagnostics allow doctors to test patients on the spot and get answers in minutes, rather than sending samples to a lab for analysis. The “flashlight” your GP uses to view the inside of your eye (known as an <a href="https://medlineplus.gov/ency/article/003881.htm">ophthalmoscope</a>) is a great example. This allows doctors to detect abnormal blood flow in the eye, deformations of the cornea (the outermost clear layer of the eye), or swollen optical discs (a round section at the back of the eye where the nerve link to the brain begins). Swollen discs are a sign of elevated pressure inside your head (or in the worst case, a brain tumour) that could be <a href="https://www.hopkinsmedicine.org/health/conditions-and-diseases/headache/increased-intracranial-pressure-icp-headache">causing your headaches</a>. The invention of <a href="https://openmedscience.com/lighting-the-way-in-healthcare-the-transformative-role-of-lasers-in-medicine/">lasers and LEDs</a> has enabled many other miniaturised technologies to be provided at the bedside or clinic rather than in the lab. <a href="https://theconversation.com/whats-a-pulse-oximeter-should-i-buy-one-to-monitor-covid-at-home-174457">Pulse oximetry</a> is a famous example, where a clip attached to your finger reports how well your blood is oxygenated. It does this by <a href="https://www.howequipmentworks.com/pulse_oximeter/">measuring</a> the different responses of oxygenated and de-oxygenated blood to different colours of light. Pulse oximetry is used at hospitals (and <a href="https://theconversation.com/whats-a-pulse-oximeter-should-i-buy-one-to-monitor-covid-at-home-174457">sometimes at home</a>) to monitor your respiratory and heart health. In hospitals, it is also a valuable tool for detecting <a href="https://www.thelancet.com/journals/lancet/article/PIIS0140-6736(12)60107-X/fulltext">heart defects in babies</a>. <h2>2. Looking at molecules</h2> Now, back to that blood test. Analysing a small amount of your blood can diagnose <a href="https://theconversation.com/blood-tests-and-diagnosing-illness-what-can-blood-tell-us-about-whats-happening-in-our-body-80327">many different diseases</a>. A machine called an automated “full blood count analyser” tests for general markers of your health. This machine directs focused beams of light through blood samples held in small glass tubes. It counts the number of blood cells, determines their specific type, and reports the level of haemoglobin (the protein in red blood cells that distributes oxygen around your body). In minutes, this machine can provide a <a href="https://www.nuffieldhealth.com/article/inside-the-pathology-lab-what-happens-to-my-blood">snapshot</a> of your overall health. For more specific disease markers, blood serum is separated from the heavier cells by spinning in a rotating instrument called a centrifuge. The serum is then exposed to special chemical stains and enzyme assays that change colour depending on whether specific molecules, which may be the sign of a disease, are present. These colour changes can’t be detected with the naked eye. However, a light beam from an instrument called a <a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC5476943/#R88">spectrometer</a> can detect tiny amounts of these substances in the blood and determine if the biomarkers for diseases are present, and at what levels. <h2>3. Medical imaging</h2> Let’s re-visit those medical images your GP ordered. The development of fibre-optic technology, made famous for transforming high-speed digital communications (such as the NBN), allows light to get inside the body. The result? High-resolution optical imaging. A common example is an <a href="https://www.medicalnewstoday.com/articles/153737#risks-and-side-effects">endoscope</a>, where fibres with a tiny camera on the end are inserted into the body’s natural openings (such as your mouth or anus) to examine your gut or respiratory tracts. Surgeons can insert the same technology through tiny cuts to view the inside of the body on a video screen during <a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC9553337/">laparoscopic surgery</a> (also known as keyhole surgery) to diagnose and treat disease. <h2>How about the future?</h2> Progress in nanotechnology and a better understanding of the interactions of light with our tissues are leading to new light-based tools to help diagnose disease. These include: <ul> <li> <a href="https://onlinelibrary.wiley.com/doi/full/10.1002/advs.201903441">nanomaterials</a> (materials on an extremely small scale, many thousands of times smaller than the width of a human hair). These are being used in next-generation sensors and new diagnostic tests </li> <li> <a href="https://www.nature.com/articles/s41587-019-0045-y">wearable optical biosensors</a> the size of your fingernail can be included in devices such as watches, contact lenses or finger wraps. These devices allow non-invasive measurements of sweat, tears and saliva, in real time </li> <li> AI tools to analyse how blood serum scatters infrared light. This has allowed researchers to build a <a href="https://www.advancedsciencenews.com/powerful-diagnostic-approach-uses-light-to-detect-virtually-all-forms-of-cancer/">comprehensive database</a> of scatter patterns to detect <a href="https://onlinelibrary.wiley.com/doi/full/10.1002/aisy.202300006">any cancer</a> </li> <li> a type of non-invasive imaging called <a href="https://www.ncbi.nlm.nih.gov/books/NBK554044/">optical coherence tomography</a> for more detailed imaging of the eye, heart and skin </li> <li> fibre optic technology to deliver a tiny microscope into the body on the <a href="https://www.uwa.edu.au/projects/microscope-in-a-needle">tip of a needle</a>. </li> </ul> So the next time you’re at the GP and they perform (or order) some tests, chances are that at least one of those tests depend on light to help diagnose 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/231379/count.gif?distributor=republish-lightbox-basic" alt="The Conversation" width="1" height="1" /> <a href="https://theconversation.com/profiles/matthew-griffith-1539353">Matthew Griffith</a>, Associate Professor and ARC Future Fellow and Director, UniSA Microscopy and Microanalysis Facilities, <a href="https://theconversation.com/institutions/university-of-south-australia-1180">University of South Australia</a> Image credits: Shutterstock This article is republished from <a href="https://theconversation.com">The Conversation</a> under a Creative Commons license.

For type 2 diabetes, focusing on when you eat – not what – can help control blood sugar

<div class="theconversation-article-body"> <a href="https://theconversation.com/profiles/evelyn-parr-441878">Evelyn Parr</a>, <a href="https://theconversation.com/institutions/australian-catholic-university-747">Australian Catholic University</a> and <a href="https://theconversation.com/profiles/brooke-devlin-2237174">Brooke Devlin</a>, <a href="https://theconversation.com/institutions/the-university-of-queensland-805">The University of Queensland</a> Type 2 diabetes affects <a href="https://www.aihw.gov.au/reports/diabetes/diabetes/contents/how-common-is-diabetes/type-2-diabetes">1.2 million Australians</a> and accounts for <a href="https://www.diabetesaustralia.com.au/about-diabetes/type-2-diabetes/">85-90%</a> of all diabetes cases. This chronic condition is characterised by high blood glucose (sugar) levels, which carry serious <a href="https://www.thelancet.com/journals/lancet/article/PIIS0140-6736(17)30058-2/abstract">health</a> risks. <a href="https://www.nature.com/articles/nrendo.2017.151">Complications</a> include heart disease, kidney failure and vision problems. Diet is an important way people living with type 2 diabetes manage blood glucose, alongside exercise and medication. But while we know individualised, professional dietary advice improves blood glucose, it can be <a href="https://linkinghub.elsevier.com/retrieve/pii/S0168822717317588">complex</a> and is not always <a href="https://www.publish.csiro.au/py/PY13021">accessible</a>. <a href="https://www.sciencedirect.com/science/article/pii/S0168822724008039">Our new study</a> looked at the impact of time-restricted eating – focusing on when you eat, rather than what or how much – on blood glucose levels. We found it had similar results to individualised advice from an accredited practising dietitian. But there were added benefits, because it was simple, achievable, easy to stick to – and motivated people to make other positive changes. <h2>What is time-restricted eating?</h2> Time-restricted eating, also known as <a href="https://www.annualreviews.org/content/journals/10.1146/annurev-nutr-082018-124320">the 16:8 diet</a>, became popular for weight loss around 2015. Studies have since shown it is also an <a href="https://jamanetwork.com/journals/jamanetworkopen/fullarticle/2811116">effective way</a> for people with type 2 diabetes to manage blood glucose. Time-restricted eating involves limiting when you eat each day, rather than focusing on what you eat. You restrict eating to a window during daylight hours, for example between 11am and 7pm, and then fast for the remaining hours. This can sometimes naturally lead to also eating less. Giving your body a break from constantly digesting food in this way helps align eating with natural <a href="https://doi.org/10.1111/jne.12886">circadian rhythms</a>. This <a href="https://doi.org/10.1111/jnc.15246">can help</a> regulate metabolism and improve overall health. For people with type 2 diabetes, there may be specific benefits. They often have their <a href="https://doi.org/10.2337/dc12-2127">highest blood glucose</a> reading in the morning. Delaying breakfast to mid-morning means there is time for physical activity to occur to help reduce glucose levels and prepare the body for the first meal. <h2>How we got here</h2> We ran an <a href="https://www.mdpi.com/2072-6643/12/11/3228">initial study</a> in 2018 to see whether following time-restricted eating was achievable for people with type 2 diabetes. We found participants could easily stick to this eating pattern over four weeks, for an average of five days a week. Importantly, they also had improvements in blood glucose, spending less time with high levels. <a href="https://www.mdpi.com/2072-6643/12/2/505">Our previous research</a> suggests the reduced time between meals may play a role in how the hormone insulin is able to reduce glucose concentrations. <a href="https://doi.org/10.1001/jamanetworkopen.2023.39337">Other studies</a> have confirmed these findings, which have <a href="https://doi.org/10.1186/s12986-021-00613-9">also shown</a> notable improvements in HbA1c. This is a <a href="https://www.ncbi.nlm.nih.gov/books/NBK304271/">marker</a> in the blood that represents concentrations of blood glucose over an average of three months. It is the <a href="https://journals.sagepub.com/doi/10.4137/BMI.S38440">primary clinical tool</a> used for diabetes. However, these studies provided intensive support to participants through weekly or fortnightly meetings with researchers. While we know this level of support <a href="https://www.nature.com/articles/0802295">increases</a> how likely people are to stick to the plan and improves outcomes, it is not readily available to everyday Australians living with type 2 diabetes. <h2>What we did</h2> In our <a href="https://www.sciencedirect.com/science/article/pii/S0168822724008039">new study</a>, we compared time-restricted eating directly with advice from an <a href="https://dietitiansaustralia.org.au/working-dietetics/standards-and-scope/role-accredited-practising-dietitian">accredited practising dietitian</a>, to test whether results were similar across six months. We recruited 52 people with type 2 diabetes who were currently managing their diabetes with up to two oral medications. There were 22 women and 30 men, aged between 35 and 65. Participants were randomly divided into two groups: diet and time-restricted eating. In both groups, participants received four consultations across the first four months. During the next two months they managed diet alone, without consultation, and we continued to measure the impact on blood glucose. In the diet group, consultations focused on changing their diet to control blood glucose, including improving diet quality (for example, eating more vegetables and limiting alcohol). In the time-restricted eating group, advice focused on how to limit eating to a nine-hour window between 10am and 7pm. Over six months, we measured each participant’s blood glucose levels every two months using the HbA1c test. Each fortnight, we also asked participants about their experience of making dietary changes (to what or when they ate). <h2>What we found</h2> We found time-restricted eating was as effective as the diet intervention. Both groups had reduced blood glucose levels, with the greatest improvements occurring after the first two months. Although it wasn’t an objective of the study, some participants in each group also lost weight (5-10kg). When surveyed, participants in the time-restricted eating group said they had adjusted well and were able to follow the restricted eating window. Many told us they had family support and enjoyed earlier mealtimes together. Some also found they slept better. After two months, people in the time-restricted group were looking for more dietary advice to further improve their health. Those in the diet group were less likely to stick to their plan. Despite similar health outcomes, time-restricted eating seems to be a simpler initial approach than making complex dietary changes. <h2>Is time-restricted eating achievable?</h2> The main barriers to following time-restricted eating are social occasions, caring for others and work schedules. These factors may prevent people eating within the window. However, there are many benefits. The message is simple, focusing on when to eat as the main diet change. This may make time-restricted eating more translatable to people from a wider variety of socio-cultural backgrounds, as the types of foods they eat don’t need to change, just the timing. Many people don’t have access to more individualised support from a dietitian, and receive nutrition advice from their GP. This makes time-restricted eating an alternative – and equally effective – strategy for people with type 2 diabetes. People should still try to stick to <a href="https://www.eatforhealth.gov.au/guidelines/guidelines">dietary guidelines</a> and prioritise vegetables, fruit, wholegrains, lean meat and healthy fats. But our study showed time-restricted eating may also serve as stepping stone for people with type 2 diabetes to take control of their health, as people became more interested in making diet and other positive changes. Time-restricted eating might not be appropriate for everyone, especially people on medications which don’t recommend fasting. Before trying this dietary change, it’s best speak to the healthcare professional who helps you manage diabetes.<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/241472/count.gif?distributor=republish-lightbox-basic" alt="The Conversation" width="1" height="1" /> <a href="https://theconversation.com/profiles/evelyn-parr-441878">Evelyn Parr</a>, Research Fellow in Exercise Metabolism and Nutrition, Mary MacKillop Institute for Health Research, <a href="https://theconversation.com/institutions/australian-catholic-university-747">Australian Catholic University</a> and <a href="https://theconversation.com/profiles/brooke-devlin-2237174">Brooke Devlin</a>, Lecturer in Nutrition and Dietetics, School of Human Movement and Nutrition Sciences, <a href="https://theconversation.com/institutions/the-university-of-queensland-805">The University of Queensland</a> Image credits: Shutterstock This article is republished from <a href="https://theconversation.com">The Conversation</a> under a Creative Commons license.

Six people found dead in luxury hotel

A disturbing theory has emerged after six people were found dead in a luxury hotel room in central Bangkok. According to Bangkok’s Metropolitan Police commissioner Thiti Saengsawang, hotel staff at the Grand Hyatt Erawan discovered the bodies of six people in a fifth-floor room after they missed check out time by more than 24 hours. After concluding that the incident did not appear to be a robbery and none of the bodies showed any signs of physical violence, Thai Police are exploring the possibility that the people were poisoned. Police shared that they "needed to find out the motives", and that the deaths were the result of a "killing", not a suicide. Authorities conformed they are investigating the potential poisoning after Thiti said cups with traces of a white powder were located in the room, along with untouched food that had been ordered earlier. As police continue their investigation into the shocking deaths, they are currently searching for a seventh person who was part of the hotel booking and is now a possible suspect. Two of the dead were US citizens of Vietnamese background, while the other four were Vietnamese nationals. Thiti said police believe one member of the group had tried to reach the door to escape but fell and died before they could get there. The Thai government issued a statement after the killings, with Thai Prime Minister Srettha Thavisin saying, "There were no signs of a struggle," adding, "We need to conduct an autopsy." He also "ordered all agencies to urgently take action to avoid impact on tourism,” given that the luxury hotel is situated in a popular tourist area. Image credits: BBC / Royal Thai Police

Health retreat responds to woman's suspected mushroom poisoning death

The alternative health centre where Rachael Dixon died after consuming a drink allegedly containing <a href="https://www.oversixty.com.au/health/caring/woman-dies-after-suspected-mushroom-poisoning-at-health-retreat" target="_blank" rel="noopener">poisonous mushrooms</a> have issued a public statement on the incident. The 53-year-old and her friends took part in a holistic wellness retreat at Soul Barn Creative Wellbeing Centre when Dixon fell ill on Saturday night after <span style="background-color: #ffffff; color: #212529; font-family: -apple-system, 'system-ui', 'Segoe UI', Roboto, 'Helvetica Neue', Arial, sans-serif, 'Apple Color Emoji', 'Segoe UI Emoji', 'Segoe UI Symbol', 'Noto Color Emoji'; font-size: 16px;">she allegedly crushed up mushrooms<span style="background-color: #ffffff; color: #212529; font-family: -apple-system, 'system-ui', 'Segoe UI', Roboto, 'Helvetica Neue', Arial, sans-serif, 'Apple Color Emoji', 'Segoe UI Emoji', 'Segoe UI Symbol', 'Noto Color Emoji'; font-size: 16px;"> and consumed them in a drink. While her two friends were rushed to hospital and released a few days later, Dixon went into cardiac arrest, and despite best efforts by paramedics, she died at the scene just after 12am. Soul Barn, a self-described “creative wellbeing centre” specialising in holistic and alternative practices issued a statement on Thursday saying they were devastated by the incident. They also claimed that the event on Saturday that Dixon attended was not run by the centre or facilitated by any of its staff. “Soul Barn hires out workshop (spaces) to external businesses and facilitators,” they said. “The event which took place on April 13 was a private event, and those facilitating the event do not work for or represent Soul Barn in any way. “None of our regular therapists staff or facilitators were present at any point during this event. “We share the shock and devastation of everyone involved, and our hearts are with those families affected.” The health centre will remain closed while police investigate Dixon's death and a report is being prepared for the coroner.
