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

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

Could not getting enough sleep increase your risk of type 2 diabetes?

<div class="theconversation-article-body"> <p><em><a href="https://theconversation.com/profiles/giuliana-murfet-1517219">Giuliana Murfet</a>, <a href="https://theconversation.com/institutions/university-of-technology-sydney-936">University of Technology Sydney</a> and <a href="https://theconversation.com/profiles/shanshan-lin-1005236">ShanShan Lin</a>, <a href="https://theconversation.com/institutions/university-of-technology-sydney-936"><em>University of Technology Sydney</em></a></em></p> <p>Not getting enough sleep is a common affliction in the modern age. If you don’t always get as many hours of shut-eye as you’d like, perhaps you were concerned by news of a <a href="https://jamanetwork.com/journals/jamanetworkopen/fullarticle/2815684">recent study</a> that found people who sleep less than six hours a night are at higher risk of type 2 diabetes.</p> <p>So what can we make of these findings? It turns out the relationship between sleep and diabetes is complex.</p> <h2>The study</h2> <p>Researchers analysed data from the <a href="https://www.ukbiobank.ac.uk/">UK Biobank</a>, a large biomedical database which serves as a global resource for health and medical research. They looked at information from 247,867 adults, following their health outcomes for more than a decade.</p> <p>The researchers wanted to understand the associations between sleep duration and type 2 diabetes, and whether a healthy diet reduced the effects of short sleep on diabetes risk.</p> <p>As part of their involvement in the UK Biobank, participants had been asked roughly how much sleep they get in 24 hours. Seven to eight hours was the average and considered normal sleep. Short sleep duration was broken up into three categories: mild (six hours), moderate (five hours) and extreme (three to four hours). The researchers analysed sleep data alongside information about people’s diets.</p> <p>Some 3.2% of participants were diagnosed with type 2 diabetes during the follow-up period. Although healthy eating habits were associated with a lower overall risk of diabetes, when people ate healthily but slept less than six hours a day, their risk of type 2 diabetes increased compared to people in the normal sleep category.</p> <p>The researchers found sleep duration of five hours was linked with a 16% higher risk of developing type 2 diabetes, while the risk for people who slept three to four hours was 41% higher, compared to people who slept seven to eight hours.</p> <p>One limitation is the study defined a healthy diet based on the number of servings of fruit, vegetables, red meat and fish a person consumed over a day or a week. In doing so, it didn’t consider how dietary patterns such as time-restricted eating or the Mediterranean diet may modify the risk of diabetes among those who slept less.</p> <p>Also, information on participants’ sleep quantity and diet was only captured at recruitment and may have changed over the course of the study. The authors acknowledge these limitations.</p> <h2>Why might short sleep increase diabetes risk?</h2> <p>In people with <a href="https://www.diabetesaustralia.com.au/about-diabetes/type-2-diabetes/">type 2 diabetes</a>, the body becomes resistant to the effects of a hormone called insulin, and slowly loses the capacity to produce enough of it in the pancreas. Insulin is important because it regulates glucose (sugar) in our blood that comes from the food we eat by helping move it to cells throughout the body.</p> <p>We don’t know the precise reasons why people who sleep less may be at higher risk of type 2 diabetes. But <a href="https://doi.org/10.7759/cureus.23501">previous research</a> has shown sleep-deprived people often have increased <a href="https://doi.org/10.1186/1476-511X-9-125">inflammatory markers</a> and <a href="https://doi.org/10.1007/s00125-015-3500-4">free fatty acids</a> in their blood, which <a href="https://doi.org/10.1007/s11892-018-1055-8">impair insulin sensitivity</a>, leading to <a href="https://doi.org/10.7759/cureus.23501">insulin resistance</a>. This means the body struggles to use insulin properly to regulate blood glucose levels, and therefore increases the risk of type 2 diabetes.</p> <p>Further, people who don’t sleep enough, as well as people who sleep in irregular patterns (such as shift workers), experience disruptions to their body’s natural rhythm, known as the <a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC5995632/">circadian rhythm</a>.</p> <p>This can interfere with the release of hormones like <a href="https://doi.org/10.1210/edrv.18.5.0317">cortisol, glucagon and growth hormones</a>. These hormones are released through the day to meet the body’s changing energy needs, and normally keep blood glucose levels nicely balanced. If they’re compromised, this may reduce the body’s ability to handle glucose as the day progresses.</p> <p>These factors, and <a href="https://www.science.org/doi/10.1126/sciadv.aar8590">others</a>, may contribute to the increased risk of type 2 diabetes seen among people sleeping less than six hours.</p> <p>While this study primarily focused on people who sleep eight hours or less, it’s possible longer sleepers may also face an increased risk of type 2 diabetes.</p> <p>Research has previously shown a U-shaped correlation between sleep duration and type 2 diabetes risk. A <a href="https://doi.org/10.2337/dc14-2073">review</a> of multiple studies found getting between seven to eight hours of sleep daily was associated with the lowest risk. When people got less than seven hours sleep, or more than eight hours, the risk began to increase.</p> <p>The reason sleeping longer is associated with increased risk of type 2 diabetes may be linked to <a href="https://doi.org/10.2337/dc15-0186">weight gain</a>, which is also correlated with longer sleep. Likewise, people who don’t sleep enough are more likely to be <a href="https://doi.org/10.1016/j.sleh.2017.07.013">overweight or obese</a>.</p> <h2>Good sleep, healthy diet</h2> <p>Getting enough sleep is an important part of a healthy lifestyle and may reduce the risk of type 2 diabetes.</p> <p>Based on this study and other evidence, it seems that when it comes to diabetes risk, seven to eight hours of sleep may be the sweet spot. However, other factors could influence the relationship between sleep duration and diabetes risk, such as individual differences in sleep quality and lifestyle.</p> <p>While this study’s findings question whether a healthy diet can mitigate the effects of a lack of sleep on diabetes risk, a wide range of evidence points to the benefits of <a href="https://www.who.int/initiatives/behealthy/healthy-diet">healthy eating</a> for overall health.</p> <p>The <a href="https://jamanetwork.com/journals/jamanetworkopen/fullarticle/2815684">authors of the study</a> acknowledge it’s not always possible to get enough sleep, and suggest doing <a href="https://pubmed.ncbi.nlm.nih.gov/33137489/">high-intensity interval exercise</a> during the day may offset some of the potential effects of short sleep on diabetes risk.</p> <p>In fact, exercise <a href="https://doi.org/10.1016/j.jshs.2023.03.001">at any intensity</a> can improve blood glucose levels.<!-- Below is The Conversation's page counter tag.

Centenarian blood tests give hints of the secrets to longevity

<p><em><a href="https://theconversation.com/profiles/karin-modig-1473484">Karin Modig</a>, <a href="https://theconversation.com/institutions/karolinska-institutet-1250">Karolinska Institutet</a></em></p> <p>Centenarians, once considered rare, have become commonplace. Indeed, they are the <a href="https://www.weforum.org/agenda/2021/02/living-to-one-hundred-life-expectancy/">fastest-growing demographic group</a> of the world’s population, with numbers roughly doubling every ten years since the 1970s.</p> <p>How long humans can live, and what determines a long and healthy life, have been of interest for as long as we know. Plato and Aristotle discussed and <a href="https://pubmed.ncbi.nlm.nih.gov/12092789/">wrote about the ageing process</a> over 2,300 years ago.</p> <p>The pursuit of understanding the secrets behind exceptional longevity isn’t easy, however. It involves <a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC7105197/">unravelling the complex interplay</a> of genetic predisposition and lifestyle factors and how they interact throughout a person’s life. Now our recent study, <a href="https://link.springer.com/article/10.1007/s11357-023-00936-w">published in GeroScience</a>, has unveiled some common biomarkers, including levels of cholesterol and glucose, in people who live past 90.</p> <p>Nonagenarians and centenarians have long been of intense interest to scientists as they may help us understand how to live longer, and perhaps also how to age in better health. So far, studies of centenarians have often been small scale and focused on a selected group, for example, excluding centenarians who live in care homes.</p> <h2>Huge dataset</h2> <p>Ours is the largest study comparing biomarker profiles measured throughout life among exceptionally long-lived people and their shorter-lived peers to date.</p> <p>We compared the biomarker profiles of people who went on to live past the age of 100, and their shorter-lived peers, and investigated the link between the profiles and the chance of becoming a centenarian.</p> <p>Our research included data from 44,000 Swedes who underwent health assessments at ages 64-99 - they were a sample of <a href="https://pubmed.ncbi.nlm.nih.gov/28158674/">the so-called Amoris cohort</a>. These participants were then followed through Swedish register data for up to 35 years. Of these people, 1,224, or 2.7%, lived to be 100 years old. The vast majority (85%) of the centenarians were female.</p> <p>Twelve blood-based biomarkers related to inflammation, metabolism, liver and kidney function, as well as potential malnutrition and anaemia, were included. All of these <a href="https://www.nature.com/articles/s41591-019-0719-5">have been associated</a> with ageing or mortality in previous studies.</p> <p>The biomarker related to inflammation was uric acid – a waste product in the body caused by the digestion of certain foods. We also looked at markers linked to metabolic status and function including total cholesterol and glucose, and ones related to liver function, such as alanine aminotransferase (Alat), aspartate aminotransferase (Asat), albumin, gamma-glutamyl transferase (GGT), alkaline phosphatase (Alp) and lactate dehydrogenase (LD).</p> <p>We also looked at creatinine, which is linked to kidney function, and iron and total iron-binding capacity (TIBC), which is linked to anaemia. Finally, we also investigated albumin, a biomarker associated with nutrition.</p> <h2>Findings</h2> <p>We found that, on the whole, those who made it to their hundredth birthday tended to have lower levels of glucose, creatinine and uric acid from their sixties onwards. Although the median values didn’t differ significantly between centenarians and non-centenarians for most biomarkers, centenarians seldom displayed extremely high or low values.</p> <p>For example, very few of the centenarians had a glucose level above 6.5 earlier in life, or a creatinine level above 125.</p> <p>For many of the biomarkers, both centenarians and non-centenarians had values outside of the range considered normal in clinical guidelines. This is probably because these guidelines are set based on a younger and healthier population.</p> <p>When exploring which biomarkers were linked to the likelihood of reaching 100, we found that all but two (alat and albumin) of the 12 biomarkers showed a connection to the likelihood of turning 100. This was even after accounting for age, sex and disease burden.</p> <p>The people in the lowest out of five groups for levels of total cholesterol and iron had a lower chance of reaching 100 years as compared to those with higher levels. Meanwhile, people with higher levels of glucose, creatinine, uric acid and markers for liver function also decreased the chance of becoming a centenarian.</p> <p>In absolute terms, the differences were rather small for some of the biomarkers, while for others the differences were somewhat more substantial.</p> <p>For uric acid, for instance, the absolute difference was 2.5 percentage points. This means that people in the group with the lowest uric acid had a 4% chance of turning 100 while in the group with the highest uric acid levels only 1.5% made it to age 100.</p> <p>Even if the differences we discovered were overall rather small, they suggest a potential link between metabolic health, nutrition and exceptional longevity.</p> <p>The study, however, does not allow any conclusions about which lifestyle factors or genes are responsible for the biomarker values. However, it is reasonable to think that factors such as nutrition and alcohol intake play a role. Keeping track of your kidney and liver values, as well as glucose and uric acid as you get older, is probably not a bad idea.</p> <p>That said, chance probably plays a role at some point in reaching an exceptional age. But the fact that differences in biomarkers could be observed a long time before death suggests that genes and lifestyle may also play a role.<!-- Below is The Conversation's page counter tag.

The types of insurance that aren’t worth your while

<p>While it’s important to make sure you’ve been covered, some forms of insurance aren’t really worth your while in the long run. We’ve taken a look at several types of insurance you shouldn’t really bother with, why they’re not worth your money and how you can find an alternative.</p> <p>Yes, it’s essential to make sure you’re covered, but at the same time you don’t need to waste any money.</p> <p><strong>Extended warranties</strong></p> <p>Many a salesperson has made a customer fork out that little bit extra for an “extended warranty” to go with a major electronic purchase. The thing is though, in many cases the period of time covered by the warranty is actually exactly the level you’re automatically entitled to under consumer law.</p> <p><strong>Credit protection insurance</strong></p> <p>While this type of insurance can be useful and a way to insure yourself against the possibility of something happening to your income as the result of an injury or a condition, credit protection insurance has tendency to be pretty expensive.</p> <p>A more cost effective way to ensure your payments to your credit card, personal loans or mortgages are fulfilled would be to take out a life insurance or total and permanent disability insurance policy through your individual superannuation fund.</p> <p><strong>Funeral insurance</strong></p> <p>Many people see this as a good way to ease the financial burden on their family that comes with their passing, but in reality funeral insurance is quite expensive and the premiums add up every year.</p> <p>A far better option is a prepaid funeral, funeral bonds life insurance or even a special savings account with money set aside. Just make sure you let your family know!</p> <p><strong>ID theft insurance</strong></p> <p>This is one of those types of insurance that isn’t really protecting your from becoming a victim, rather helping you deal with the costs once it’s already happened. And what’s more, you bank is usually willing to cover the costs of credit card fraud, which is one of the major problems to be associated with ID theft.</p> <p>Instead of spending money on a policy you can protect yourself from ID theft by simply keeping your personal documents safe, shredding documents such as bank account statements before throwing them away, and using antivirus software that is up to date. You can also check your credit file each year to make sure nobody’s using your identity for fake accounts.</p> <p><em>Image credits: Getty Images </em></p>

8 reasons everyone should know their blood type

<p><strong>Why you should know your blood type</strong></p> <p>What’s in a blood type? Potentially a lot, according to research, including a review of studies published in the Wiley Interdisciplinary Reviews: Systems Biology and Medicine, that connects different blood groups to everything from risk of heart disease and dementia to urinary tract infections and the norovirus.</p> <p>While none of the studies are conclusive about cause and effect (they can’t say X blood type causes Y disease) and any increased risks are still pretty small, the research does highlight the importance of knowing your type – A, B, AB, or O – and how it could affect your wellbeing.</p> <p><strong>Blood clots: Type AB, A, and B increases risk</strong></p> <p>Danish researchers studied how blood type interacts with a genetic predisposition for deep-vein thrombosis (DVT), or blood clots in the lower legs that can travel to the lungs and become life-threatening. After analysing data on about 66,000 people over more than 30 years, they found that those with type AB, A, or B had a 40 per cent higher risk of DVT than people with type O, the most common type.</p> <p>When the scientists did further analysis to see which factors have the biggest impact on DVT risk on a population level, they found that an AB blood type contributed to about 20 per cent of blood clots; genetic mutations accounted for 11 per cent, being overweight accounted for 16 per cent, and smoking accounted for six per cent.</p> <p><strong>Heart disease: Type AB, B, and A all increase risk </strong></p> <p>People whose blood type is A, B, or AB have an increased risk of heart disease and shorter life spans than people who have type O blood, according to a large study published in BMC Medicine. After following more than 50,000 middle-age and elderly people for seven years, on average, researchers found that as many as nine per cent of cardiovascular deaths were attributed to having non-O blood types.</p> <p>However, as any doctor will tell you, lifestyle factors like weight, smoking and diet, which, unlike blood type, are modifiable, have a much greater impact on heart disease.</p> <p><strong>Stomach cancer: Types A and AB increases risk </strong></p> <p>Researchers have known for a while that people with blood type A are at risk for stomach cancer. But research published in BMC Cancer shows that people with blood type AB are also at risk. Using genetic data from a large number of cases and controls, researchers found a link between both blood types and gastric cancer in Chinese populations. A review of 39 previous studies confirmed their findings.</p> <p><strong>Fertility: Type O reduces it </strong></p> <p>Women with this blood type were twice as likely to have blood levels of the hormone FSH high enough to indicate low ovarian reserve, a measure of fertility, according to a study published in Human Reproduction. Researchers couldn’t say for sure why, though. Given that type O blood is the most prevalent, it doesn’t pay to worry too much about it. Age is a far more important risk factor for fertility problems.</p> <p><strong>Pregnancy risks </strong></p> <p>This has nothing to do with your “letter” blood type or the type determined by the ABO grouping system. This has to do with what’s known as the Rhesus (Rh) factor, which determines whether your blood type is positive or negative. This could cause complications in pregnant women if the baby’s Rh blood type is different from the mother’s.</p> <p>For instance, if the mother has a negative blood type and the baby has a positive one, the mother’s body can actually build up antibodies against the baby’s blood type. Luckily, this doesn’t affect the baby, but it could have a negative effect on future pregnancies. Fortunately, doctors can give pregnant women a shot early in their pregnancy that can prevent Rh-incompatibility problems.</p> <p><strong>Dementia and memory loss: Type AB increases risk </strong></p> <p>People with type AB blood have an 82 per cent greater risk for cognitive decline later in life, according to a study published in Neurology. That’s likely because they have larger amounts of what’s known as the Factor VIII protein, which helps with blood clotting.</p> <p>Study participants with higher levels of this protein were 24 per cent more likely to develop memory problems – regardless of their blood type – than people with lower levels. Blood type, however, is far from the only, or even most important, factor that affects your risk for cognitive decline.</p> <p><strong>Stroke: Type O has the lowest risk</strong></p> <p>People with a blood type other than O (the most common) have a higher risk of cardiovascular issues such as stroke, according to a study published in the Journal of Thrombosis and Haemostasis. Biologists are still investigating why this might be; one possible explanation is that non-O blood types contain more of the Von Willebrand factor, a protein that has been connected to blood clotting and stroke in the past.</p> <p><strong>Mosquitos like Type O blood </strong></p> <p>If you find yourself scratching bug bites all summer long, your blood type might be to blame. In a one small study, researchers found that type Os are up to twice as attractive to mosquitoes as type As, with type Bs falling somewhere in the middle. </p> <p><em>Image credits: Shutterstock</em></p> <p style="box-sizing: border-box; border: 0px; margin: 0px 0px 20px; outline: 0px; padding: 0px; vertical-align: baseline; line-height: 26px;"><em>This article originally appeared on <a href="https://www.readersdigest.com.au/healthsmart/8-reasons-everyone-should-know-their-blood-type" target="_blank" rel="noopener">Reader's Digest</a>. </em></p>

"I've lost complete blood flow": Robert Irwin's near miss with python

<p>Young wildlife warrior Robert Irwin suffered a near miss during a rescue mission over the weekend, when he tried to relocate a carpet python off the road. </p> <p>The 19-year-old took to Instagram on Sunday to share a video of him almost getting bit by the wild snake. </p> <p>"Gee, that gets the heart rate up - he missed me by that much," he said when the snake struck at him. </p> <p>"He's grumpy... he's really keen on biting me... what a gorgeous snake, he's big, he's not venomous but... they're designed to constrict," he said as the python began wrapping its body around his arm to ''constrict" him. </p> <p>"He's got a good grip there, I've lost complete blood flow to my hand, it's completely blue.. and I have no feeling left in my hand," he added. </p> <p>He eventually managed to rescue the snake, and relocated it to a safe spot in the bush the day after. </p> <p>"Near miss!

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

<p><em><a href="https://theconversation.com/profiles/sapha-shibeeb-1481231">Sapha Shibeeb</a>, <a href="https://theconversation.com/institutions/rmit-university-1063">RMIT University</a></em></p> <p>Blood tests are a common medical procedure, offering valuable insights into a person’s health. Whether you’re getting a routine check-up, diagnosing a medical condition or monitoring treatment progress, understanding the process can make the experience more comfortable and effective.</p> <p>For the majority of patients, blood collections are a minor inconvenience. Others may feel <a href="https://www.sciencedirect.com/science/article/abs/pii/S0887618506000041">uneasy and anxious</a>.</p> <p>Preparation strategies can help get you through the procedure.</p> <h2>How blood is collected</h2> <p>During venipuncture (blood draw), the phlebotomist (blood collector) inserts a needle through the skin into a vein and a small amount of blood is collected and transferred into a test tube.</p> <p>Tubes are sent to a laboratory, where the blood is analysed. A laboratory technician may count or examine cells and measure the levels of minerals/salts, enzymes, proteins or other substances in the sample. For some tests, blood plasma is separated out by spinning (centrifuging) the sample. Others pass a light beam through the sample to determine the amount of a chemical present.</p> <p>For collection, the phlebotomist usually selects a vein in the crook of your elbow, where veins are readily accessible. Blood can also be drawn from veins in the wrists, fingers or heels. A tourniquet may be applied to restrict blood flow and make the chosen vein puff out.</p> <h2>Different tests require different preparation</h2> <p>Before a blood test, the GP or health-care provider will give you specific instructions.</p> <p>These may include fasting for up to 12 hours or temporarily discontinuing certain medications.</p> <p>It is crucial to follow these guidelines meticulously as they can significantly impact the accuracy of your test results. For example, fasting is required before glucose (blood sugar) and lipids (blood fats) testing because blood sugar and cholesterol levels typically increase after a meal.</p> <p>If the blood test requires fasting, you will be asked not to eat or drink (no tea, coffee, juice or alcohol) for about eight to 12 hours. Water is allowed but smoking should be avoided because it can increase <a href="https://diabetesjournals.org/care/article/19/2/112/19825/Acute-Effect-of-Cigarette-Smoking-on-Glucose">blood sugar, cholesterol and triglyceride levels</a>.</p> <p>Generally, you will be asked to fast overnight and have the blood collection done in the morning. Fasting for longer than 15 hours could impact your results, too, by causing dehydration or the release of certain chemicals in the blood.</p> <p>If you have diabetes, you must consult your doctor prior to fasting because it can increase the risk of hypoglycemia (low blood sugar) in people with type 1 diabetes. Most type 2 diabetics can safely fast before a blood test but there are some exceptions, such as people who are taking certain medications including insulin.</p> <h2>5 tips for a better blood test</h2> <p>To improve your blood collection experience, consider these tips:</p> <p><strong>1. Hydrate</strong></p> <p>Drink plenty of water right up to 30 minutes before your appointment. Adequate hydration improves blood flow, making your veins more accessible. Avoid <a href="https://academic.oup.com/labmed/article/34/10/736/2657269">strenuous exercise</a> before your blood test, which can increase some blood parameters (such as liver function) while decreasing others (such as sodium).</p> <p><strong>2. Loose clothing</strong></p> <p>Wear clothing that allows easy access to your arms to ensure a less stressful procedure.</p> <p><strong>3. Manage anxiety</strong></p> <p>If the sight of blood or the procedure makes you anxious, look away while the needle is inserted and try to keep breathing normally. Distraction can help – virtual reality has been <a href="https://pubmed.ncbi.nlm.nih.gov/31889358/">trialled</a> to reduce needle anxiety in children. You could try bringing something to read or music to listen to.</p> <p><strong>4. Know your risk of fainting</strong></p> <p>If you’re prone to fainting, make sure to inform the phlebotomist when you arrive. You can have your blood drawn while lying down to minimise the risk of passing out and injury. Hydration helps maintain blood pressure and can also <a href="https://www.ahajournals.org/doi/10.1161/01.CIR.0000101966.24899.CB">reduce the risk</a> of fainting.</p> <p><strong>5. Discuss difficult veins</strong></p> <p>Some people have smaller or scarred veins, often due to repeated punctures, <a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC4989034/">chemotherapy</a> or blood thinner use. In such cases, venipuncture may require multiple attempts. It is important to talk to the phlebotomist if you feel discomfort or significant pain. A finger prick can be performed as an alternative for some tests, such as blood glucose levels. But other comprehensive tests require larger blood volume.</p> <h2>Blood draws after lymph node removal</h2> <p>Historically, there were concerns about drawing blood from an arm that had undergone lymph node removal. This was due to the risk of <a href="https://www.cancer.gov/about-cancer/treatment/side-effects/lymphedema/lymphedema-pdq#:%7E:text=Lymphedema%20is%20the%20build%2Dup,the%20way%20that%20it%20should.">lymphedema</a>, a condition marked by fluid build-up in the affected arm. Lymph nodes may have been removed (<a href="https://www.ncbi.nlm.nih.gov/books/NBK564397/#:%7E:text=Lymph%20node%20dissection%2C%20also%20known,surgical%20management%20of%20malignant%20tumors.">lymphadenectomy</a>) for cancer diagnosis or treatment.</p> <p>However, a <a href="https://ascopubs.org/doi/10.1200/JCO.2015.61.5948">2016 study</a> showed people who’ve had lymph nodes removed are not at a higher risk of developing lymphedema following blood draws, even when drawing blood from the affected arm.</p> <h2>After your blood test</h2> <p>The whole blood test procedure usually lasts no more than a few minutes. Afterwards, you may be asked to apply gentle pressure over a clean dressing to aid clotting and reduce swelling.</p> <p>If you do experience swelling, bruising or pain after a test, follow general first aid procedures to alleviate discomfort. These include applying ice to the site, resting the affected arm and, if needed, taking a pain killer.</p> <p>It is usually recommended you do not do heavy lifting for a few hours after a blood draw. This is to prevent surges in blood flow that could prevent clotting where the blood was taken.<!-- Below is The Conversation's page counter tag.

We found 3 types of food wasters, which one are you?

<p><em><a href="https://theconversation.com/profiles/trang-nguyen-1454838">Trang Nguyen</a>, <a href="https://theconversation.com/institutions/university-of-adelaide-1119">University of Adelaide</a> and <a href="https://theconversation.com/profiles/patrick-oconnor-109973">Patrick O'Connor</a>, <a href="https://theconversation.com/institutions/university-of-adelaide-1119">University of Adelaide</a></em></p> <p>Each year, Australian households discard about <a href="https://workdrive.zohopublic.com.au/external/06152b9ff5971843391f39fc4d32a847e56fb907c167a4a645887b0a4bc43000">2.5 million tonnes of food</a>. Most (73%) of this food waste <a href="https://www.sciencedirect.com/science/article/pii/S0959652622042081">ends up in landfill</a>.</p> <p>This is costly and contributes to <a href="https://pubmed.ncbi.nlm.nih.gov/37118273/">escalating greenhouse gas emissions</a>, because food waste rotting in landfill produces methane. So reducing household food waste and diverting it from landfill saves money, improves food security and benefits the environment.</p> <p>To address the problem, we need to understand how people generate and dispose of food waste. In <a href="https://doi.org/10.1016/j.foodqual.2023.105000">our new study</a>, we found households fell into three categories – based on the amount of food wasted, how much of that waste was avoidable and how it was sorted. These insights into consumer behaviour point to where the most worthwhile improvements can be made.</p> <figure><iframe src="https://www.youtube.com/embed/JvAFaD5f1Lo?wmode=transparent&amp;start=0" width="440" height="260" frameborder="0" allowfullscreen="allowfullscreen"></iframe><figcaption></figcaption></figure> <h2>Three types of households</h2> <p>We conducted an online survey of 939 households in metropolitan Adelaide between April and May 2021.</p> <p>The sample closely matched the national Australian population in terms of gender, age and income.</p> <p>We asked about the types of food waste produced, the amount of food waste typically discarded in a week and motivations towards reducing and sorting food waste.</p> <p>We identified three distinct types of households:</p> <p><strong>Warriors</strong> are typically older and highly motivated to reduce and sort food waste. They generate minimal waste (9.6 litres per week), such as bones and vegetable peels, that is mostly unavoidable. This group comprised 39.6% of the sample.</p> <p><strong>Strugglers</strong> mainly consist of families with children who produce the largest amount of food waste (33.1 litres per week). They produce the highest proportion of avoidable food waste, such as uneaten fruits and vegetables, bread and cereals. They are moderately motivated to reduce and sort food waste, but more than half of their food waste still ends up in landfill. This group made up 19.6% of the sample.</p> <p><strong>Slackers</strong> are generally younger. They show little concern about reducing or sorting food waste. Slackers produce the smallest amount of food waste overall (9 litres a week), but the proportion of avoidable food waste (such as mixed leftovers) is significantly higher (38.9%) compared to warriors (24.5%). They are more than twice as likely to live in units, with 17.2% doing so, compared to just 7.8% of warriors.

The focus shifts to how we handle and dispose of this waste.</p> <p>When households engage in food waste recycling they <a href="https://doi.org/10.3390/su131911099">start thinking more</a> about their behaviour including purchasing and cooking.</p> <p>In Australia, food waste management is mainly the responsibility of local councils.</p> <p>There are three ways to target household food waste management and drive behavioural change:</p> <ul> <li> <p>providing kerbside collection of food organics and garden organics, also known as “FOGO”</p> </li> <li> <p>changing social norms around food waste</p> </li> <li> <p>offering economic incentives and disincentives.</p> </li> </ul> <h2>1. Providing a FOGO system</h2> <p>Councils should provide this option at a minimum. This ensures sufficient infrastructure is available to support motivated households to sort food waste.</p> <p>Unfortunately <a href="https://experience.arcgis.com/experience/e6b5c78e1dac47f88e7e475ffacfc49b">fewer than half of Australian councils</a> provide a garden organics system and only a quarter of councils provide a FOGO system.</p> <p>You can explore <a href="https://experience.arcgis.com/experience/e6b5c78e1dac47f88e7e475ffacfc49b">the FOGO interactive map</a> to see how your area stacks up.</p> <p><a href="https://www.greenindustries.sa.gov.au/resources/adelaide-metro-kerbside-waste-performance-report-2021-22">Most councils in metropolitan Adelaide</a> provide access to food waste recycling through the FOGO bin. But <a href="https://doi.org/10.1016/j.jclepro.2022.134636">our research</a> indicates more than half of household food waste still ends up in landfill. So we need additional programs to promote more sustainable behaviours.</p> <h2>2. Changing social norms</h2> <p>Social norms, the unspoken rules about what behaviours are deemed appropriate, can drive behavioural change.</p> <p>Examples of promoting social norms around food waste reduction include a <a href="https://www.stopfoodwaste.com.au/stop-food-waste-nationwide-consumer-campaign-summit-communique/">nationwide consumer campaign</a> on stopping food waste and the <a href="https://www.cityofadelaide.com.au/resident/recycling-waste/kitchen-caddies/">kitchen caddy</a> for benches to increase convenience for collecting food waste.</p> <p>But our research suggests some groups, like slackers, remain unmotivated without additional incentives. Economic incentives might motivate this group to engage in more sustainable behaviours.</p> <h2>3. Economic incentives</h2> <p>Currently, Australians pay for waste management through their council rates. This is a “pay-as-you-own” system.</p> <p>The cost is determined by the property’s value, regardless of the amount of waste generated. Renters indirectly contribute to this cost by paying rent.</p> <p>Neither owner-occupiers nor renters have any incentive to reduce waste generation when the cost is levied on property value rather than the amount of waste.</p> <p>An alternative approach gaining momentum in other parts of the world is the “pay-as-you-throw” approach, such as <a href="https://www.collectors2020.eu/wcs-ppw/stockholm-se/">Stockholm</a> and <a href="https://pocacito.eu/sites/default/files/WasteCharging_Taipei.pdf">Taipei</a>. This system charges households based on the weight of their waste, usually the general waste that needs to be discarded in landfill, while the collection of food waste and other recyclables remains free to encourage waste sorting.</p> <p>Recent <a href="https://doi.org/10.1016/j.jclepro.2023.137363">research</a> in Italy shows pay-as-you-throw schemes result in significant reductions in both the quantity of waste and costs associated with waste disposal in many Italian municipalities.</p> <p>The reduced costs flow on to savings for councils that could potentially reduce waste management fees passed on to homeowners and renters through council rates. Giving households incentives to reduce waste and find alternatives to disposal encourages residents to place a higher value on food that may otherwise be sent to landfill.</p> <h2>Reducing food waste is a win-win</h2> <p>Tackling food waste is a win-win for people and the planet. It’s worth using various approaches to encourage people to change their behaviour.</p> <p>Our findings can help inform the design of interventions aimed at reducing and sorting food waste in specific segments of the Australian population.<!-- Below is The Conversation's page counter tag.

The best cruise cabin for every type of need

<p><strong>So many options</strong></p> <p>Cruise accommodations – also known as staterooms or cabins – are your home away from home while at sea. Far from a one-size-fits-all decision, there are numerous factors to consider when determining the best rooms on a cruise ship to fit your and your companions’ needs.</p> <p>From size to location to view and beyond, there are many things to keep in mind when selecting your stateroom, says Gianluca Corneli, hotel director at Royal Caribbean International. “How many will stay in the room? Is your room a place to hang out or just where you sleep?” Also, think about what you’d like to be near on the ship. “For example, consider if you would like to be near the elevator for convenience or prefer a location down the hallway with fewer guests passing by,” she says. Also factor in any ways you’d like to elevate your stay, like maybe a balcony or a suite for your next Caribbean cruise.</p> <p>It’s no wonder that some of the best cruise lines offer up to 28 different types of rooms on a single ship – they want to ensure there’s an ideal solution for every guest. Let’s focus on upgrading your room choice to the perfect fit for your specific needs.</p> <p><strong>Best for avoiding seasickness</strong></p> <p><span style="text-decoration: underline;"><em>Choose</em></span>: the middle of the ship, on a low deck</p> <p>Picture a ship like a seesaw – the most movement will be felt on either end, while the middle stays fairly even-keel. “Middle and low, that’s where you want to be,” says cruise expert Dori Saltzman, senior editor with trade publication Travel Market Report. “While you don’t need to be on the absolute lowest passenger deck, you don’t want to go above the middle of the ship (vertical wise). You also want to try to be as middle (horizontal wise) as possible.</p> <p>If cabins in the middle of the ship aren’t available, she says to choose aft over forward, because the more forward a cabin is, the more you’ll feel the motion of the ocean. And while this may seem counter-intuitive, be sure to book a cabin with a window or balcony, so you can keep your eyes on the horizon if you start feeling queasy.</p> <p><strong>Best for great views</strong></p> <p><span style="text-decoration: underline;"><em>Choose</em></span>: a cabin with a balcony, preferably at the back of the ship</p> <p>While you can always go to the upper decks of any ship for 360-degree views of your surroundings, there’s no greater cruise ship luxury than enjoying the scenery from your own private balcony. They may also be called verandah cabins. Balconies are the perfect place to enjoy a cup of coffee in the morning or glass of champagne during a spectacular sunset and pretend you’re all alone at sea.</p> <p>And some of the absolute best rooms on a cruise ship are located at the rear, where you’ll also be treated to the photo-worthy wake left behind, which is a fun way to mark your ship’s progress. Balconies are also nice for having access to fresh air when you want it, it can be very soothing to listen to the sounds of the ocean from your stateroom, and you’ll have a better chance of spotting wildlife along your cruise too.</p> <p><strong>Best for light sleepers</strong></p> <p><span style="text-decoration: underline;"><em>Choose</em></span>: a deck filled with other guest cabins and away from elevators</p> <p>Finding the best rooms on a cruise ship for light sleepers usually takes a little research, but that due diligence will pay off come bedtime. “You need your cabin to be located away from any bank of elevators, but also away from crew entrances,” says Saltzman. So being surrounded by other cabins of people who want to sleep too is a safe bet. “You also don’t want your cabin to be located above the ship’s main theatre, underneath any restaurants where you can hear the chairs scraping on the floor or under/over any of the lounges that have music late into the night.”</p> <p>Finally, you don’t want to be on a low deck that’s too aft or too forward, as you may end up above the engines or the anchor, which makes a lot of noise when it’s lowered and raised. You may feel a bit like Goldilocks trying to choose that perfect cabin on your next romantic cruise, but the reward of peace and quiet will be priceless.</p> <p><strong>Best for a little more space</strong></p> <p><span style="text-decoration: underline;"><em>Choose</em></span>: a forward-facing cabin</p> <p>While you aren’t likely to find a balcony on a forward-facing cabin, you may find more interior space than similarly priced mid-ship cabins. Why? There are some odd angles in forward-facing cabins that the designers had to work around, thanks to the slanted style of the front of a ship. Those odd angles may work in your favour when it comes to square footage.</p> <p>It’s important to note that while these are some of the best rooms on a cruise ship for extra space, you will experience the most movement in a front-facing cabin, so this choice is not an ideal position for anyone prone to motion sickness.</p> <p><strong>Best for cruising with little kids</strong></p> <p>Most cruise lines offer family-friendly cruises and specific cabins suited for kids, which can be a mix of in-room amenities and proximity to other areas of the ship children will love. “On Disney’s ships, all cabins have two bathrooms, one with a sink and toilet and the other with a shower/bath combo (a small minority of rooms do not have the tub) for families that need the little one to be able to take a bath, while everyone else is still able to wash up,” says Saltzman.</p> <p>“Another good option is the Family Harbour cabins on Carnival’s Vista-class ships (Vista, Horizon, Panorama) and Excel-class ships (Mardi Gras, Celebration). Similar to the Disney cabins, these have two bathrooms, one a full one with a shower, sink and toilet, and the other with a sink and shower/tub combo.”</p> <p><strong>Best for staying on a budget</strong></p> <p><span style="text-decoration: underline;"><em>Choose</em></span>: an interior cabin</p> <p>Unless you’re worried about feeling claustrophobic – since there will be no porthole or window to the outside world – an interior cabin is a nice option for saving money (we’re talking $300 for 7-day cruises). Not only is it the lowest-priced cabin type, which means you’ll have more funds to put toward excursions, a drink package or souvenirs, but you’ll also be able to take midday naps or sleep in later because there won’t be any light sneaking in.</p> <p>Another positive is that an interior cabin might encourage you to spend more of your free time roaming around the ship, meeting other people and getting more involved in activities, since you may not find it desirable to spend your time beyond sleeping and showering in a windowless box.</p> <p><strong>Best for mobility disabilities </strong></p> <p><span style="text-decoration: underline;"><em>Choose</em></span>: an accessible stateroom</p> <p>For passengers with limited mobility or no mobility, most major cruise lines offer accessible staterooms in a variety of room types (inside cabin, ocean view and balcony). These options do vary based on the cruise line and the age of the ship, so it’s best to research this in advance and factor the accessible options available into your cruise planning process.</p> <p>Accessible rooms tend to be larger than standard cabins to accommodate wheelchair or scooter users, and they also feature larger bathrooms. Additionally, some rooms will have emergency-call buttons or specific amenities for hearing or vision-impaired guests. For instance, the fully accessible rooms on Holland America Line provide adequate turning space, accessibility routes throughout the room, roll-in showers, wheelchair access on both sides of the bed, handlebars in the shower and hand-held shower heads, says Sissel Bergersen, director of rooms division, Holland America Line. Before you lock in a booking, it may be best to call the cruise line and explain your needs so they can help steer you toward the perfect cabin.</p> <p><strong>Best for being spoiled rotten</strong></p> <p><span style="text-decoration: underline;"><em>Choose</em></span>: a cabin with butler service or a spa cabin</p> <p>For travellers who like adult-only cruises or who are yearning for a little extra pampering, the best rooms on a cruise ship fall into one of two categories. The first is a suite that comes with butler service, where you’ll have someone helping with all the details you don’t want to spend your precious holiday time tending to – like reserving prime-time dinner slots at specialty restaurants, booking shore excursions, packing and unpacking and even drawing rose petal bubble baths. Rooms at this level may also come with exclusive access to private pools, clubs and lounges with more luxurious touches and solitude than you’ll find elsewhere on the ship.</p> <p>The other category that’s becoming increasingly popular is spa suites. On Norwegian Cruise Line, the Haven Spa Suite, Spa Club Balcony Suites and Spa Balcony (available on the Norwegian Escape, Norwegian Bliss and Norwegian Epic) have varying amenities that range from more tranquil room décor with an oversized shower and body spray jets to priority access to Mandara Spa. And on Celebrity Cruises, the AquaClass staterooms are focused on wellness, with a pillow menu, complimentary fitness pass, preferential rates on spa packages, healthy room-service menu options, an exclusive restaurant, a spa concierge, access to the SEA Thermal Suite and a yoga mat for use onboard.</p> <p><strong>Best for solo cruisers</strong></p> <p><em><span style="text-decoration: underline;">Choose</span></em>: a cruise line that offers single rooms or waives single supplements</p> <p>Solo cruises are a wonderful experience, yet so many cruise lines penalise single cruisers by forcing them to pay a ‘single supplement.’ This surcharge is added to the fare of a solo passenger, since cruise room pricing is generally based on double occupancy. This fee can be an additional 10 per cent all the way up to a full 100 per cent of the rate, making solo cruising unaffordable for many travellers.</p> <p>Instead, look for cruise lines that offer single staterooms, like Celebrity, which has the Edge Single Stateroom with Infinite Veranda (available on Celebrity Edge, Celebrity Apex, Celebrity Beyond and Celebrity Ascent) and the Single Inside Stateroom on Celebrity Silhouette. Other cruise lines, including Holland America Line, Royal Caribbean and Norwegian Cruise Line, also offer single cabins – these special solo and studio cabins aren’t subject to single supplements. Occasionally, you may even find cruise lines running special promotions and waiving their single supplement for a regular-size room.</p> <p><em>Image credits: Getty Images</em></p> <p><em>This article originally appeared on <a href="https://www.readersdigest.com.au/travel/cruising/the-best-cruise-cabin-for-every-type-of-need" target="_blank" rel="noopener">Reader's Digest</a>. </em></p>

The best skin-care routine for oily skin, according to dermatologists

<p><strong>What is oily skin?</strong></p> <p>Oily skin is exactly what it sounds like: skin characterised by the production of a lot of oil. If you’re constantly dealing with shininess, always feel like your face has been hit by an oil slick by the end of the day or tend to notice a bit of oil buildup across your nose and forehead, it may be time to invest in a skin-care routine for oily skin.</p> <p>Need another reason to target oily skin with your daily regimen? Because it produces so much oil (also known as sebum), this skin type often goes hand in hand with acne. But take heart: if you’re battling breakouts, you’re in good company. According to the Australasian College of Dermatologists, acne is the most common of skin diseases and up to 85 per cent of Australians will develop it during their lifetime.</p> <p>Luckily, there are great skin-care formulations that can help oily skin avoid acne and stay healthy, and some formulas may even help curb oil production. Finding the best skin-care routine for oily skin just takes a little know-how, so we reached out to board-certified dermatologists Dr Corey L. Hartman and Dr David Kim to find out what makes a great oily-skin routine.</p> <p><strong>What causes oily skin?</strong></p> <p>“Oily skin is genetic, and it has to do with the size and activity of the oil glands that are associated with the hair follicles,” Dr Hartman explains. “That means if you have thicker hair, you may have thicker or larger oil glands.”</p> <p>Another thing that can impact the amount of oil your skin produces? Hormones. That’s why acne, which is so often associated with oily skin, commonly shows up during puberty, and for those who menstruate, around their periods.</p> <p>Now that you know what triggers oiliness, it’s time to put together your ideal skin-care routine for oily skin – and it’s simpler than it sounds. As Dr Kim notes, when it comes to oily skin types, less is more. “It’s best not to add too many layers for oily skin,” he says. “Otherwise, it can clog your pores and cause acne flares.”</p> <p>If you’re ready to get glowing (but not shiny!) skin, follow the regimen below. Trust us: skin care for oily skin has never been easier.</p> <p><strong>Skin-care routine for oily skin</strong></p> <p>The heart of a good skin-care routine for oily skin has four main daily steps:</p> <p>Cleanser</p> <p>Toner</p> <p>Moisturiser</p> <p>Sunscreen</p> <p>There are additional steps you can add in if necessary or as needed:</p> <p>Exfoliator</p> <p>Acne treatment</p> <p>If hitting all those steps sounds intimidating, don’t worry. We have everything you need to know, including product recommendations.</p> <p><strong>1. Cleanser</strong></p> <p>Every good skin-care routine – including one for oily skin – begins with a good cleanser. You want to use it twice a day: once in the morning to prep your skin to apply your products, and again at night to take off any debris you’ve collected throughout the day.</p> <p>You might’ve heard that you can skip a morning cleansing, but rinsing without washing is better suited to a skin-care routine for dry skin. If yours is oily, go ahead and use a cleanser in the morning and at night.</p> <p>Dr Hartman says that for oily skin, the best face wash is likely “something a little astringent” that uses hydroxy acids or benzoyl peroxide. “You don’t want to do so much that it pushes you in the direction of overly drying,” he explains. That can lead your skin to produce more oil, a process called rebound oiliness.</p> <p>As for the best face wash formulations, Dr Hartman recommends staying away from oils, which can sometimes be comedogenic. (In other words, they can clog your pores.) Instead, look for gel, foam or cream cleansers.</p> <p><strong>2. Toner</strong></p> <p>Toner is technically an optional skin-care step, but many dermatologists recommend it for oily skin because it can help regulate sebum. These watery formulas are meant to eliminate any leftover makeup and grime left after cleansing, while treating the skin with helpful ingredients.</p> <p>What’s the best way to use them? “Once or twice a day on a cotton pad,” says Dr Kim. “Apply to [your] full face.”</p> <p>The best toner for you depends on your goals: Are you aiming for better skin texture? Regulated oil production? A combination of both? According to Dr Kim, if you have oily skin, look for gentle exfoliating acids, such as glycolic or lactic acid, to gently resurface the skin. Or go with salicylic acid to help with sebum control.</p> <p>You’ll know you’ve found the right one when your skin feels soft and smooth after use, not tight or dry. Luckily, unlike the harsh toners of the past, today’s formulas are much gentler and more foolproof.</p> <p><strong>3. Moisturiser</strong></p> <p>Yes, oily skin needs moisturiser. It may sound counterintuitive, but keeping your skin moisturised means it won’t have to work as hard to keep hydration levels up! In fact, Dr Hartman says it’s one of the keys to holding off rebound oiliness. You want to use it morning and night, after cleansing.</p> <p>When looking for the best moisturiser for oily skin, the formula is everything. “I like things that are less creamy and more like a serum or gel base,” says Dr Hartman. “You want something light, nothing too heavy, nothing too emollient,” he explains. In other words, look for terms like daily or sheer, and skip thicker formulas – night creams and bottles marked intense may be too heavy for oily skin. One thing to stay away from: oils, as they can be comedogenic, meaning they may clog pores.</p> <p><strong>4. Sunscreen</strong></p> <p>Sun damage impacts every skin type, including oily skin, so having SPF in your morning routine is non-negotiable. And, yes, that means you need to use it year-round, even on cloudy days and in the winter.   (And don’t forget the scalp sunscreen!)</p> <p>Admittedly, sunscreen can make your skin look a little oily, so finding a nongreasy sunscreen is essential (more on that in a second). But Dr Kim reassures us that’s not impossible. “If you’re using good skin care that helps exfoliate and regulate sebum production, you should be able to wear sunscreen without feeling too greasy,” he says.</p> <p>When it comes to the best face sunscreens for oily types, lightweight daily formulas win. Just be sure yours has an SPF of 30 or higher.</p> <p>Whether you reach for a mineral or chemical sunscreen is a matter of personal preference, and it often comes down to how they wear on your skin (mineral sunscreens can sometimes leave a white cast). “The goal is to find your favourite sunscreen – chemical or mineral – and actually use it every day,” says Dr Kim.</p> <p>Powder sunscreens are a good option for touching up oily skin – they allow you to reapply SPF on the go while soaking up oil. Sunscreen oils, on the other hand, are best avoided. “These can clog the pores,” he says.</p> <p><strong>Exfoliant</strong></p> <p>Exfoliators help remove the dead skin cells that can mix with sebum and clog pores, which is why exfoliating can be an important step in your routine.</p> <p>There are two categories of exfoliants: chemical (like glycolic and salicylic acid or retinols, which increases cell turnover) and physical (scrubs that use friction). Dr Hartman recommends starting with chemical exfoliators, as “they’re a more controlled way of exfoliation,” he says.</p> <p>Apply an exfoliator once or twice a week – or more if your skin can handle it – either in the morning or at night. You may need to start slow, only using it more often if you don’t experience irritation. Beyond that, exfoliate only for very special events, when you really want a glow. That way, you won’t trigger irritation.</p> <p>Dr Hartman’s go-to products for oily skin are prescription retinoids or over-the-counter retinols – not surprising, as these vitamin A derivatives are darlings of the dermatology world. But retinoids are harsh chemicals. “For retinol, start using a pea-size [amount] only twice weekly, and let your skin develop tolerance,” says Dr Kim. You’ll want to apply retinol at night and be extra careful about wearing sunscreen during the day.</p> <p>For people who don’t tolerate them well, Dr Hartman says an alpha hydroxy acid (like glycolic acid) or beta hydroxy acid (like salicylic acid) is a great alternative. If you prefer a physical facial scrub, remember: the finer the particles, the better.</p> <p><strong>Acne treatment</strong></p> <p>First, forget about spot-treating blemishes – if you’re dealing with acne, Dr Kim insists it’s best to treat your whole face. That way, you prevent breakouts before they have a chance to form. And if you’re struggling with breakouts, he says, “you should use at least one prescription cream on your full face to treat existing pimples and prevent new ones.”</p> <p>Heads up: retinoids don’t just aid exfoliation; they can treat acne too. If you’re using a retinoid for acne control and have sensitive skin, you may want to consider this your combo acne and exfoliating treatment. It covers both needs, and including an additional exfoliant in your skin-care routine may cause irritation, especially if your skin is sensitive.</p> <p>If acne is something you grapple with more than occasionally, see your dermatologist for a prescription cream – your doctor will pick the formula that’s best for your skin. If it’s a retinoid, you’ll use this at night.</p> <p>But if you only experience the occasional pimple and would rather go for an over-the-counter option, you’ve got some choices. First things first: you’re going to want a cream rather than a medicated face wash. Sure, face washes offer some acne-fighting ingredients, but you wash them away almost immediately. “Acne wash stays on your face for five seconds, so you need something that will stay on your skin the whole day or night,” Dr Kim explains.</p> <p>While you may see a few other ingredients (like azelaic acid) pop up in the acne world, when it comes to OTC options, there are two all-star ingredients: salicylic acid and benzoyl peroxide. Both are effective, but of the two, benzoyl peroxide tends to get a little more love – it’s especially effective when combined with antibiotics (under a doctor’s care), according to the Mayo Clinic.</p> <p>Just be aware that it can bleach fabrics, so make sure to let it really soak in before getting dressed. And, again, make sure to apply it to your whole face, not just one pimple. Remember, your goal is to avoid pimples in the first place.</p> <p><strong>Skin-care tips experts swear by</strong></p> <p>Armed with our dermatologist-approved skin-care routine for oily skin, you’re well on your way to a less-greasy face. But there are a couple more things to consider as you follow this regimen.</p> <p><strong>Skin care and exercise</strong></p> <p>You know you need to wash your face in the morning and at night. But what if you’re feeling particularly grimy midday? If you work out in the middle of the day, for instance, should you wash your face if you have oily skin? “You probably don’t need to do that,” says Dr Hartman. “Twice a day is enough.”</p> <p>Adding an additional cleansing session may dry your skin out, causing more oiliness. You do want to rinse your face, however. That’ll prevent the sweat, debris and oil from mixing and clogging your pores. And it has the added bonus of leaving you refreshed after a gruelling workout.</p> <p><strong>Smart product use</strong></p> <p>Take your time when introducing ingredients. Before slathering a new product all over your face, do a spot test to make sure your skin can handle it. And when dealing with ingredients like benzoyl peroxide and retinoids, which some people find irritating, start slow to acclimate your face, building to more frequent use as your skin adjusts to the ingredient.</p> <p><em>Image credits: Getty Images</em></p> <p><em>This article originally appeared on <a href="https://www.readersdigest.com.au/healthsmart/the-best-skin-care-routine-for-oily-skin-according-to-dermatologists?pages=1" target="_blank" rel="noopener">Reader's Digest</a>. </em></p>

Type 1 diabetes sufferers in for price hike

<p>Those suffering from Type 1 diabetes will be hit with a steep hike in prescription costs when a life-changing insulin is removed from the Pharmaceutical Benefits Scheme (PBS) in April 2023.</p> <p>Local Member for Fairfax Ted O’Brien and Shadow Minister for Health and Aged Care Senator Anne Ruston have revealed 15,000 Australian families will be affected when the drug Fiasp becomes less accessible from April 1.</p> <p>Fiasp is a mealtime insulin that is designed to improve blood sugar control in diabetes sufferers at a faster rate than alternative diabetes medications.</p> <p>Mr O’Brien said he was made aware of the issue by the mother of a young high school student on the Sunshine Coast “whose quality of life will now be at risk from the government’s decision”.</p> <p>“Freya Goldston is a 14-year-old, high-performing student in my electorate who will tell anybody about the remarkable impact that this medicine has had on her life,” Mr O’Brien said.</p> <p>“Freya’s family will have her prescription go from around $7 to more than $280 at a time when households are already under serious financial pressure.</p> <p>“The Labor Government needs to provide an immediate solution to support the 15,000 families who will otherwise need to start making decisions about what household expenses they can cut back on to afford this life-changing medicine.”</p> <p>Mr O’Brien shared the former Coalition Government listed Fiasp on the PBS in 2019 to ensure accessible prices to the fast-acting insulin for diabetes patients.</p> <p>“But now, without any consultation or support for the patients impacted, the government’s decision to suddenly remove Fiasp from the PBS is sending the price soaring,” he said.</p> <p>A spokesperson for Health Minister Mark Butler said his office was alerted of the drug manufacturer Novo Nordisk removing Fiasp from the PBS on February 22 2023.</p> <p>“The minister’s office is now working with the department and Novo Nordisk,” the spokesperson said.</p> <p>“We understand the decision by Novo Nordisk to remove Fiasp from the PBS has been concerning for many Australians living with diabetes and their families.”</p> <p>The spokesperson did not comment on whether there was consultation or support for impacted diabetics when Mr Butler was approached about the removal of Fiasp.</p> <p>Nearly 28,000 people have signed a petition online created by Belinda Moore called “Save Fiasp from falling off the PBS”.</p> <p>“The Australian diabetes community will keep advocating until we witness no evidence of inequitable access to diabetes services, clinicians, technology and therapies.”</p> <p>Ms Ruston also said he was disappointed in the government's decision as Australians are already suffering from a cost-of-living crisis, and the removal of Fiasp from the PBS will affect thousands of Australians.</p> <p>“The government must urgently guarantee that they will provide sufficient support to ensure the viability of affordable diabetes medications in Australia,” Ms Ruston said.</p> <p><em>Image credit: Shutterstock</em></p>

Why certain types of music make our brains sing, and others don’t

<p>A few years ago, Spotify published an online <a href="https://www.francetvinfo.fr/culture/musique/spotify-devoile-une-cartographie-des-gouts-musicaux_3320877.html">interactive map</a> of musical tastes, sorted by city. At the time, <a href="https://open.spotify.com/artist/5TEGxYftTkeKmLXkZjHNUE">Jeanne Added</a> prevailed in Paris and Nantes, and London was partial to local hip hop duo <a href="https://open.spotify.com/artist/31lnFZEM6ysvjOx59VyxRE">Krept and Kronan</a>. It is well established that music tastes vary over time, by region and even by social group. However, most brains look alike at birth, so what happens in them that causes us to end up with such disparate music tastes?</p> <h2>Emotions – a story of prediction</h2> <p>If one presented you with a unknown melody and suddenly stopped it, you could be able to sing the note you think fit the best. At least, professional musicians could! In a <a href="https://www.jneurosci.org/content/41/35/7449">study</a> published in the Journal of Neuroscience in September 2021, we show that similar prediction mechanisms are happening in the brain every time we listen to music, whithout us being necessarly conscious of it. Those predictions are generated in the auditory cortex and merged with the note that was actually heard, resulting in a “prediction error”. We used this prediction error as a sort of neural score to measure how well the brain could predict the next note in a melody.</p> <p>Back in <a href="https://books.google.fr/books/about/Emotion_and_Meaning_in_Music.html?id=HuWCVGKhwy0C&amp;redir_esc=y">1956</a>, the US composer and musicologist Leonard Meyer theorised that emotion could be induced in music by a sense of satisfaction or frustration derived from the listener’s expectations. Since then, academic advances have helped identify a link between musical expectations and other more complex feelings. For instance, participants in <a href="https://onlinelibrary.wiley.com/doi/10.1111/cogs.12477">one study</a> were able to memorize tone sequences much better if they could first accurately predict the notes within.</p> <p>Now, basic emotions (e.g., joy, sadness or annoyance) can be broken down into two fundamental dimensions, valence and psychological activation, which measure, respectively, how positive an emotion is (e.g., sadness versus joy) and how exciting it is (boredom versus anger). Combining the two helps us define these basic emotions. Two studies from <a href="https://link.springer.com/article/10.3758/s13415-013-0161-y">2013</a> and <a href="http://webprojects.eecs.qmul.ac.uk/marcusp/papers/SauveEtAl2018.pdf">2018</a> showed that when participants were asked to rank these two dimensions on a sliding scale, there was a clear relationship between prediction error and emotion. For instance, in those studies, music notes that were less accurately predicted led to emotions with greater psychological activation.</p> <p>Throughout the history of <a href="https://www.nature.com/articles/nrn1406">cognitive neuroscience</a>, pleasure has often been linked to the reward system, particularly with regard to learning processes. <a href="https://www.cell.com/current-biology/pdf/S0960-9822(14)01207-X.pdf">Studies</a> have shown that there are particular dopaminergic neurons that react to prediction error. Among other functions, this process enables us to learn about and predict the world around us. It is not yet clear whether pleasure drives learning or vice versa, but the two processes are undoubtedly connected. This also applies to music.</p> <p>When we listen to music, the greatest amount of pleasure stems from events predicted with only a moderate level of accuracy. In other words, overly simple and predictable events – or, indeed, overly complex ones – do not necessarily induce new learning and thus generate only a small amount of pleasure. Most pleasure comes from the events falling in between – those that are complex enough to arouse interest but consistent enough with our predictions to form a pattern.</p> <h2>Predictions dependent on our culture</h2> <p>Nevertheless, our prediction of musical events remains inexorably bound to our musical upbringing. To explore this phenomenon, a group of researchers met with the Sámi people, who inhabit the region stretching between the northernmost reaches of Sweden and the Kola Peninsula in Russia. Their traditional singing, known as yoik, differs vastly from Western tonal music due to limited exposure to Western culture.</p> <p>For a <a href="http://users.jyu.fi/%7Eptoiviai/pdf/Cognition.Yoiks.pdf">study</a> published in 2000, musicians from Sámi regions, Finland and the rest of Europe (the latter coming from various countries unfamiliar with yoik singing) were asked to listen to excerpts of yoiks that they had never heard before. They were then asked to sing the next note in the song, which had been intentionally left out. Interestingly, the spread of data varied greatly between groups; not all participants gave the same response, but certain notes were more prevalent than others within each group. Those who most accurately predicted the next note in the song were the Sámi musicians, followed by the Finnish musicians, who had had more exposure to Sámi music than those from elsewhere in Europe.</p> <h2>Learning new cultures through passive exposure</h2> <p>This brings us to the question of how we learn about cultures, a process known as enculturation. For example, <a href="https://www.musicnotes.com/now/tips/a-complete-guide-to-time-signatures-in-music/">musical time</a> can be divided in different ways. Western musical traditions generally use <a href="https://www.youtube.com/watch?v=e-CEd6xrRQc">four-time signatures</a> (as often heard in classic rock ‘n’ roll) or <a href="https://www.youtube.com/watch?v=-tn2S3kJlyU">three-time signatures</a> (as heard in waltzes). However, other cultures use what Western musical theory calls an asymmetrical meter. Balkan music, for instance, is known for asymmetrical meters like <a href="https://www.youtube.com/watch?v=b65FN-X3OkA">nine-time</a> or <a href="https://www.youtube.com/watch?v=EhVzrqvAsZI">seven-time signatures</a>.</p> <p>To explore these differences, a <a href="https://journals.sagepub.com/doi/full/10.1111/j.0956-7976.2005.00779.x">2005 study</a> looked at folk melodies with either symmetrical or asymmetrical meters. In each one, beats were added or removed at a specific moment – something referred to as an “accident” – and then participants of various ages listened to them. Regardless of whether the piece had a symmetrical or asymmetrical meter, infants aged six months or less listened for the same amount of time. However, 12-month-olds spent considerably more time watching the screen when the “accidents” were introduced into the symmetrical meters compared to the asymmetrical ones. We could infer from this that the subjects were more surprised by an accident in a symmetrical meter because they interpreted it as a disruption to a familiar pattern.</p> <p>To test this hypothesis, the researchers had a CD of Balkan music (with asymmetrical metres) played to the infants in their homes. The experiment was repeated after one week of listening, and the infants spent an equal amount of time watching the screen when the accidents were introduced, regardless of whether the meter was symmetrical or asymmetrical. This means that through passive listening to the Balkan music, they were able to build an internal representation of the musical metric, which allowed them to predict the pattern and detect accidents in both meter types. </p> <p>A <a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC2927013/pdf/nihms225442.pdf">2010 study</a> found a strikingly similar effect among adults – in this case, not for rhythm but for pitch. These experiments show that passive exposure to music can help us learn the specific musical patterns of a given culture – formally known as the process of enculturation.</p> <p>Throughout this article, we have seen how passive music listening can change the way we predict musical patterns when presented with a new piece. We have also looked at the myriad ways in which listeners predict such patterns, depending on their culture and how it distorts perception by making them feel pleasure and emotions differently. While more research is needed, these studies have opened new avenues toward understanding why there is such diversity in our music tastes. What we know for now is that our musical culture (that is, the music we have listened to throughout life) warps our perception and causes our preference for certain pieces over others, whether by similarity or by contrast to pieces that we have already heard.</p> <p><em>Image credits: Getty Images</em></p> <p><em>This article originally appeared on <a href="https://theconversation.com/why-certain-types-of-music-make-our-brains-sing-and-others-dont-194100" target="_blank" rel="noopener">The Conversation</a>. </em></p>

<p>A study across 20 countries has strengthened a link between lowering blood pressure, and reducing the risk of dementia.</p> <p>The meta-analysis, published in the European Heart Journal, draws on clinical trial data from 28,008 participants, to show the strongest link to date between medication that lowers blood pressure, and reduced dementia risk.</p> <p>“We know that high blood pressure is a risk factor for dementia – especially high blood pressure in midlife, so say 40 to 65 years of age,” says lead author Dr Ruth Peters, an associate professor at the University of New South Wales and program lead for dementia in the George Institute’s Global Brain Health Initiative.</p> <p>“But there has been some uncertainty about whether lowering blood pressure, especially in older adults, would reduce risk of dementia.</p> <p>“What we’ve done is take five really high-quality clinical trials and combine them into one dataset, which gave us the ability to really look at this question and look at the relationship between blood pressure-lowering tablets – antihypertensives – and dementia.”</p> <p>The five studies were all double-blind, randomised clinical trials – the ‘gold standard’ in medical research – with participants hailing from 20 different countries.</p> <p>The average age of the participants was 69, and participants were followed up an average of four years after doing the trial.</p> <p>Participants who took antihypertensives had a significantly lower chance of being diagnosed with dementia than those who took placebos.</p> <p>Dementia affects 50 million people worldwide: a number projected to triple by 2050.</p> <p>According to The Lancet’s 2020 Commission on dementia, treatment for hypertension (high blood pressure) is “the only known effective preventive medication for dementia,” all other methods of reducing your risk come from lifestyle and environment.</p> <p>“The strength of this study is the use of individual patient data in a meta-analysis of data drawn from randomised controlled trials of blood pressure medication. This is the first time such data has been meta-analysed,” says Professor Kaarin Anstey, a senior principal research scientist at Neuroscience Research Australia and the UNSW.</p> <p>“This is important for informing clinical practice,” adds Anstey, who was not involved with the study.</p> <p>Professor Nicolas Cherbuin, head of the Australian National University’s Centre for Research on Ageing, Health and Wellbeing, says that the study is “well-designed”, and reflects research by his team showing that higher blood pressure is linked to lower brain volumes and poorer brain health.</p> <p>“The diagnostic procedure and criteria used are well-established, the sample size is large, those with dementia at baseline were excluded,” says Cherbuin.</p> <p>But he points out that the study didn’t find an effect of blood pressure medication on cognitive decline, and nor did it include participants with mild cognitive impairment, who would be “more likely to convert”.</p> <p>Anstey points out that “inevitably” the participants in the cohort are now quite old, and thus may be different to populations developing dementia now.</p> <p>“Clinical trials involve highly selected samples and often exclude diverse ethnic groups,” she adds.</p> <p>“I hope that this reinforces the importance of blood pressure control for brain health,” says Peters.</p> <p>But she emphasises that, while this is useful news for preventing dementia in mid-life, people of all ages can improve their brain health by other means.</p> <p>“It’s not just blood pressure lowering – it has to be taken in the context of a healthy lifestyle.”</p> <p><strong>This article originally appeared on <a href="https://cosmosmagazine.com/health/dementia-blood-pressure-meta/" target="_blank" rel="noopener">cosmosmagazine.com</a> and was written by Ellen Phiddian.</strong></p> <p><em>Image: Shutterstock</em></p>

The 10 “types” of grandparents

<p>In his book, <em>The Grandparent Guide: The Definitive Guide to Coping with the Challenges of Modern Grandparenting</em>, Dr. Arthur Kornhaber, a psychiatrist and founder of a non-profit organisation that promotes the importance of grandparenting identified 10 special roles grandparents play in the lives of grandchildren, all showing the profound impact grandparents can have on children’s lives. Which role, or roles, do you most identify with?</p> <p><strong>Ancestor –</strong> “You function as an ambassador to the past, a powerful figure in the present, and a role model for the future.”</p> <p><strong>Buddy –</strong> “You’re a pal, secret confidante, and at times, even a light-hearted conspirator.”</p> <p><strong>Hero –</strong> “The fact that you have lived in times and places so far removed from your grandchild’s everyday experiences imbues you with heroic qualities.”</p> <p><strong>Historian –</strong> “Sharing your own life experiences as well as those of your ancestors will give your grandchild a sense of continuity and belonging.”</p> <p><strong>Mentor –</strong> “You are a cheerleader firing her imagination, inspiring her dreams, nurturing her spirit, and encouraging her intellectual growth while giving her a sense of self-worth.”</p> <p><strong>Role model –</strong> “Your actions show your children and grandchildren how they should behave as grandparents of the future.”</p> <p><strong>Spiritual guide –</strong> “Acting as a spiritual guide involves teaching your grandchild to harvest such fruits of the spirit as love, tolerance, compassion, reverence, joy, peace, gentleness, faith, and kindness.”</p> <p><strong>Teacher –</strong> “As a grandparent, you have the right and the responsibility to run your own classroom about life, to develop your own curriculum, and to pass on your wisdom, knowledge, and life experience.”</p> <p><strong>Student –</strong> “Just as you teach and inspire your grandchild with your knowledge, she can teach and inspire you with her knowledge of contemporary times across generations and motivate you to jumpstart your capacity to grow and change.”</p> <p><strong>Wizard –</strong> “Activate your own wizardry and be your grandchild’s companion in the preternatural world of make-believe and illusion, of dreams and surprises. Fly together on the wings of fancy and enjoy the flight!”</p> <p><em>Image: Getty Images</em></p>

Is just 4.5 kg of weight loss really going to help stop type 2 diabetes?

<p>A new study has found that losing just 4.5 kg of weight could be the difference between getting type 2 diabetes and not.</p> <p>That’s the headline on some of the publicity surrounding the research, except like all these studies, it’s significantly more complicated than that. So, let’s talk about it.</p> <p>The study looked at around 100,000 nurses and other health professionals from a few different US cohort studies that started in the late 1980s.</p> <p>The team looked at up to 10 years of weight changes and tracked the participants for 24 years to see if they developed type 2 diabetes.</p> <p>They also looked at the way that those who lost more than 4.5 kg, dieted. They split them into seven categories – low-calorie diet; exercise; low-calorie diet plus exercise; fasting; commercial weight loss program; diet pills; and a combination of fasting, commercial and diet pills.</p> <p>When the team looked at the original results, they found something surprising: In the overall population, those who lost more than 4.5 kilograms had a higher risk of being diagnosed with type 2 diabetes than those that didn’t diet or try and lose weight.</p> <p>This was particularly striking for those that lost the weight due to limiting calories, diet pills, fasting, or weight loss programs.</p> <p>The researchers then split the data into BMI categories – those who were ‘normal’ weight or underweight, those who were overweight and those who were obese.</p> <p>The findings of a higher risk of type 2 diabetes after trying to lose weight broadly held in both the ‘underweight’ and ‘normal’ as well as the ‘overweight’ categories.</p> <p>“We were a bit surprised when we first saw the positive associations of weight loss attempts with faster weight gain and higher type 2 diabetes risk among lean individuals,” says Qi Sun, a nutrition researcher at the TH Chan Harvard School of Public Health.</p> <p>As you can see in this figure below, the risk of type 2 diabetes only reduced a little – significantly less than the increased risk of type 2 diabetes if you lost over 4.5 kilograms while at a normal BMI.</p> <p><img src="https://oversixtydev.blob.core.windows.net/media/2022/10/figures.jpg" alt="" width="1280" height="720" /></p> <p>As noted in the paper, the vast majority of people try and diet at some point or another – in 2013 to 2016 almost half of US adults reported trying to lose weight.</p> <p>But almost everyone either doesn’t succeed or puts all the weight back on, normally within a few months.</p> <p>This study backs that up. After 10 years, those who tried to lose weight (known as the weight loss strategies group) gained more weight than those that hadn’t.</p> <p>“Participants who lost 4.5+ kg were likely to gain more weight and have higher risk of type 2 diabetes than those who did not attempt to lose weight,” the team writes in their paper.</p> <p>“By 10 years of follow-up, all weight loss strategy groups were associated with more weight gain than the reference group (ranging from 1.7% for exercise to 6.6% for fasting, commercial weight loss program and pills).”</p> <p>It’s important to note here that exercise and eating well is not bad for you. Exercise has been shown time and time again to help us live longer, and eating more fruits and vegetables and less processed food is better for us.</p> <p>However, this study is a good reminder that just losing weight – particularly in ways like weight loss pills, calorie restriction and weight loss programs are not a silver bullet for keeping us healthy.</p> <p>In fact, depending on who you are, it seems it might make it worse.</p> <p>The conclusion from the study is worth reading in full:</p> <p>In conclusion, in individuals with obesity, losing 4.5+ kg of body weight intentionally was associated with less weight gain and lower T2D risk, regardless of the methods used to achieve the weight loss. However, for individuals who were lean, losing 4.5+ kg was not associated with these health benefits. Of all WLSs, exercise was optimal for long-term weight control and T2D prevention. Our data support current guidelines for body weight management, such as that issued by the Obesity Society, which recommend a weight loss of 5% to 10% of baseline weight for individuals who are overweight or obese and exercise of 200 to 300 minutes per week to maintain the weight loss.</p> <p><strong>This article originally appeared on <a href="https://cosmosmagazine.com/health/diabetes-type-2-weight-loss-4-5-diet-pills-exercise/" target="_blank" rel="noopener">cosmosmagazine.com</a> and was written by Jacinta Bowler.</strong></p> <p><em>Image: Shutterstock</em></p>

Scientists have mimicked an embryo’s heart to unlock the secrets of how blood cells are born

<p>Stem cells are the starting point for all other cells in our bodies. The <a href="https://www.eurostemcell.org/blood-stem-cells-pioneers-stem-cell-research" target="_blank" rel="noopener">first such cells to be found</a> were blood stem cells – as the name suggests, they give rise to different types of blood cells.</p> <p>But there’s much we don’t know about how these cells develop in the first place. In a study published today in <a href="https://doi.org/10.1016/j.celrep.2022.111339" target="_blank" rel="noopener">Cell Reports</a>, we have shown how a lab simulation of an embryo’s beating heart and circulation lead to the development of human blood stem cell precursors.</p> <p>The tiny device mimics embryonic blood flow, allowing us to directly observe human embryonic blood formation under the microscope. These results may help us understand how we can produce life-saving therapies for patients who need new blood stem cells.</p> <h2>Growing life-saving therapies in the lab</h2> <p>To treat aggressive blood cancers such as leukaemia, patients often need extremely high doses of chemotherapy; a <a href="https://www.cancer.nsw.gov.au/myeloma/diagnosis-and-treatment/treatment/types-of-treatment/stem-cell-transplant#:%7E:text=A%20stem%20cell%20transplant%20involves%20killing%20blood%20cells,they%20are%20collected%20beforehand%20and%20kept%20in%20storage." target="_blank" rel="noopener">blood stem cell transplant</a> then regenerates blood after the treatment. These are life-saving therapies but are restricted to patients who have a suitable tissue-matched donor of blood stem cells.</p> <p>A way around this problem would be to grow more blood stem cells in the lab. Unfortunately, past experiments have shown that harvested adult blood stem cells lose their transplantation potential if grown in the lab.</p> <p>The discovery of <a href="https://en.wikipedia.org/wiki/Induced_pluripotent_stem_cell" target="_blank" rel="noopener">induced pluripotent stem cells</a> – stem cells made out of adult cells – in 2006 led to a promising new approach. Induced pluripotent stem cells are made from the patient’s own cells, so there is no problem with tissue rejection, or the ethical issues surrounding the use of IVF embryos.</p> <p>These cell lines are similar to embryonic stem cells, so they have the potential to form any tissue or cell type – hence, they are “pluripotent”. In theory, pluripotent stem cell lines could provide an unlimited supply of cells for blood regeneration because <a href="https://en.wikipedia.org/wiki/Immortalised_cell_line" target="_blank" rel="noopener">they are immortalised</a> – they can grow in the lab indefinitely.</p> <p>But the development of processes to allow us to grow particular types of tissues, organs and cell types – such as blood – has been slow and will take decades to advance. One must mimic the complex process of embryogenesis in the dish!</p> <h2>Engineering an embryonic heart</h2> <p>Current understanding of how embryonic blood stem cells develop is based on animal models. Experiments with anaesthetised zebrafish embryos have shown that blood stem cells arise in the wall of <a href="https://pubmed.ncbi.nlm.nih.gov/20154733/" target="_blank" rel="noopener">the main blood vessel, the aorta</a>, shortly after the first heartbeat. For ethical reasons, it’s obvious this type of study is not possible in human embryos.</p> <p>This is why we wanted to engineer an embryonic heart model in the lab. To achieve this, we used <a href="https://www.elveflow.com/microfluidic-reviews/general-microfluidics/a-general-overview-of-microfluidics/" target="_blank" rel="noopener">microfluidics</a> – an approach that involves manipulating extremely small volumes of liquids.</p> <p>The first step in generating blood stem cells from pluripotent stem cells is to coax the latter to form the site where blood stem cells start growing. This is known as the AGM region (aorta-gonad-mesonephros) of the embryo.</p> <p>Our miniature heart pump and circulation (3 by 3 centimetres) mimics the mechanical environment in which blood stem cells form in the human embryo. The device pumps culture media – liquids used to grow cells – around a microfluidic circuit to copy what the embryo heart does.</p> <h2>A step closer to treatment</h2> <p>Once we got the cells to form the AGM region by stimulating cells on day two of starting our cell culture, we applied what’s known as pulsatile circulatory flow from day 10 to day 26. Blood precursors entered the artificial circulation from blood vessels lining the microfluidic channels.</p> <p>Then, we harvested the circulating cells and grew them in culture, showing that they developed into various blood components – white blood cells, red blood cells, platelets, and others. In-depth analysis of gene expression in single cells showed that circulatory flow generated aortic and blood stem precursor cells found in the AGM of human embryos.</p> <p>This means our study has shown how pulsatile circulatory flow enhances the formation of blood stem cell precursors from pluripotent stem cells. It’s knowledge we can use in the future.</p> <p>The next step in our research is to scale up the production of blood stem cell precursors, and to test their transplant potential in immune-deficient mice that can accept human transplants. We can do this by using large numbers of pluripotent stem cells grown in bioreactors that also mechanically stimulate blood stem cell formation.</p> <p>If we can easily produce blood stem cells from pluripotent stem cell lines, it would provide a plentiful supply of these cells to help treatments of cancer or genetic blood diseases.</p> <p><strong>This article originally appeared on <a href="https://theconversation.com/scientists-have-mimicked-an-embryos-heart-to-unlock-the-secrets-of-how-blood-cells-are-born-190530" target="_blank" rel="noopener">The Conversation</a>.</strong></p> <p><em>Image: UNSW</em></p>

"She sat on a throne of blood": Uni professor launches another attack on Queen Elizabeth

<p>A controversial university professor has doubled down on her celebration of Queen Elizabeth's death, claiming she "sat on a throne of blood".</p> <p>Uju Anya, a linguistics professor at Pennsylvania's Carnegie Mellon University, <a href="https://oversixty.com.au/news/news/uni-professor-slammed-for-wishing-the-queen-excruciating-pain" target="_blank" rel="noopener">came under fire</a> earlier this week for a series of controversial tweets in which she hoped the Queen was in "excruciating pain" as she died. </p> <p>Now, the Nigerian-American lecturer has reiterated her claims on a podcast, saying, "This was a ruler. The very crown she had on her head signified the fact that she's a monarch was made from plunder. Diamonds. Blood diamonds."</p> <p>"The throne that she was sitting on is a throne of blood... Her very position as a monarch, the palace she lived in... were all paid for by our blood."</p> <p>She stood by her controversial tweets, which she admitted were an "emotional outburst", but said, "I said what I f****** said."</p> <p>"I was triggered by this news. It went deep into pain and trauma for me. Due to my family experience with the rule of this monarch."</p> <p>Anya also shared her thoughts on the Queen's role in the Nigerian Civil War in 1967 by showing support for the turbulent government. </p> <p>She said, "People expected me to be calm or to be... when the person who literally paid money for bombs and guns and military supplies to come and massacre your people is dying, you're not supped to dance."</p> <p>Anya's claims forced her employer to say in a statement, "We do not condone the offensive and objectionable messages posted by Uju Anya today on her social media account."</p> <p>"Free expression is core to the mission of higher education. However, the views she shared absolutely do not represent the values of the institution, nor the standards of discourse we seek to foster," they concluded.</p> <p>Despite thousands of people being up in arms over her comments and demanding an apology, others have jumped to the professor's defence. </p> <p>Over 4,000 people have signed a petition defending Anya, saying her posts on Twitter spoke to personal anguish the scholar still feels about atrocities by the British Empire decades ago that touched her family.</p> <p>Refusing to apologise, Anya once again tweeted, "If anyone expects me to express anything but disdain for the monarch who supervised a government that sponsored the genocide that massacred and displaced half my family and the consequences of which those alive today are still trying to overcome, you can keep wishing upon a star."</p> <p><em>Image credits: Getty Images / Youtube</em></p>

The 5 worst types of people on cruises

<p>There is so much for you to enjoy on a cruise – state of the art facilities, sunshine, an escape from normal life and the food.</p> <p>However, just like anywhere else you go in the world, you can never anticipate the type of people you will be surrounded by when you cruise.</p> <p>To save you wasting any unnecessary time and energy, here are the <a href="../Find%20out%20about%20the%20five%20types%20of%20people%20you%20may%20encounter%20on%20a%20cruise." target="_blank" rel="noopener"><span style="text-decoration: underline;"><strong>types of people you need to be wary</strong></span></a> of during your cruise.</p> <p><strong>1. The deckchair hog</strong></p> <p>Despite there being a limited amount of deckchairs on board, some cruisers think it is acceptable to lay their sunscreen, towels, hats and books over a deckchair in a bid to communicate that it is “taken".  Although it is common courtesy to remove your belongings if you won’t be needing the chair, unfortunately this seldom happens. If you are looking to enjoy lying by the pool, be ready to wake up early to get yourself a deckchair.</p> <p><strong>2. The buffet over-eater</strong></p> <p>These travellers think it is fine to pile up their plates with all the best food, leaving everyone else waiting for the mains to be restocked. After their meal, they are back again for as many more rounds as their stomachs can handle. There is nothing wrong with eating big portions to satisfy your hunger, however, often these people are only taking excessive amounts of food to get their money’s worth.</p> <p><strong>3. The cruise “expert”</strong></p> <p>Sometimes you can find seasoned cruisers who will share great hints about the ship and activities worth trying. Other times, you will meet a know-it-all who will criticise various elements of the cruise due to their “experience”. It is better to be surrounded by the optimistic when trying to enjoy a relaxing cruise getaway.</p> <p><strong>4. The spa dominator</strong></p> <p>Although there is only a select amount of space to be enjoyed in the spa, some travellers will go there day in and day out, not caring about whether anyone else wants to use it. It is even worse when a whole group of people are committed to using the spa for most of the trip, ignoring all their fellow cruisers who are patiently waiting to use it.</p> <p><strong>5. The entitled cruiser</strong></p> <p>You will see this kind of traveller clicking their fingers at staff or making another complaint about something that wasn’t up to their standard. If things go wrong it is definitely necessary to get staff to fix the issue, however, no matter the situation you can still be kind.</p> <p>What kind of people have you noticed on cruises?

10 tips to find the perfect style for your body type

<p>Whether we are 30 or 60, we all want to look like the best version of ourselves by wearing clothing that accentuates our silhouette in a positive manner. Fashion should be fun and a thing which boosts our confidence, not something that causes us stress and hits us with a dose of low self-esteem.</p> <p>No matter what your body shape is, you can always take your everyday style to an elegant and sophisticated state, that is always timeless but also modern. Here are 10 tips to help you find the perfect style for your body shape.</p> <p><strong>Hourglass</strong></p> <p>If your bust and hips are full and your waist is smaller, then you have an hourglass figure. The best way to flatter this body shape to your advantage is by wearing fit and flare dresses which will accentuate your tiny waist and leave room for the fuller areas of your body. Other design silhouettes like peplum tops or body hugging pieces will also help to flatter your body shape.</p> <p><strong>Apple shape</strong></p> <p>When your silhouette is fuller throughout, just like the shape of an apple, but your legs are slim, then you need tunic tops to give the upper part of your bodya flowy shape and sheath dresses (which are very much like a T shirt in design but longer) to straighten your apple shaped body. To balance the bottom area of your body, you can wear slim pants, preferably tailored pieces to accentuate the tiniest area on your body.</p> <p><strong>Heavy bust</strong></p> <p>When your bust area is quite large and the rest of your body is smaller, then you might want to minimise this feature. One way of balancing your heavy bust and make it appear smaller than it is, is by wearing V-neck tops and knitwear, as well as buttoned up shirts with the top three buttons left open. You can also use the timeless design of a wrap dress with this kind of body shape.</p> <p><strong>Pear shape</strong></p> <p>One of the most common body shapes out there, a pear shaped body, with a tiny top part and a larger bottom area needs boxy shaped tops to make the bust area look bigger and A-line dresses to hide the wider hips and thighs. Bootleg pants can also help to balance the wide hips by widening the area around your ankles.</p> <p><strong>Rectangle shape</strong></p> <p>When your body is quite straight, with relatively no curves, then you have a rectangle shape and you need clothing to help you create the idea of curves. High neck tops like polo necks and collared blouses, as well as statement jewelry to add more volume to your neck area are all ways you can use clothing to add the suggestion of curves on your body.</p> <p><strong>Carrot shape</strong></p> <p>A relatively unknown definition for a body shape, a carrot shape is when you have a broad shoulder area but the rest of your silhouette is quite tiny. There are two ways you can work this body shape. You can either use your bottom area to create volume there by wearing skirts and trousers with pleats or you can accentuate the shoulder area with embellishment and keep the rest of your body tiny by wearing body hugging pieces.</p> <p><strong>Accessories</strong></p> <p>Choosing accessories that are not unproportioned to your body is how you will continue to flatter your body shape, so if you have a full bust, don’t wear a dainty necklace that will appear very small in that area.</p> <p><strong>Use colour</strong></p> <p>We tend to steer clear of color when we are older but using color to highlight the best areas of your body is another way of playing up your shape.</p> <p><strong>Be wary of prints</strong></p> <p>While prints are great to bring that bold touch to your everyday look, try to avoid wearing prints on those areas of your body which you want to minimize.</p> <p><strong>Shoes always help</strong></p> <p>You may not like wearing heels as much as you did in earlier decades but even a pair of comfortable shoes with a small heel can really help to elongate your body and help to make you look slimmer.</p> <p><em>Image credits: Getty Images</em></p>
