France has become the first European country to reimburse the costs associated with remote monitoring of patients with chronic medical conditions. The initiative aims to reduce hospitalizations and enhance patient well-being. Starting from July 1, the country's health insurance scheme, Assurance Maladie, has begun refunding the expenses incurred during these remote checks, which are sometimes conducted through video calls. What is medical remote monitoring? Medical remote monitoring, known as "télésurveillance médicale" in French, involves the use of video or biomedical devices to allow healthcare professionals to monitor a patient's condition. This can include devices such as glycemic monitors, pacemakers, or other biomedical tools. It's important to note that télésurveillance médicale differs from téléconsultation, which refers to doctor appointments conducted via video. However, video calls may be incorporated into medical remote monitoring if necessary. Distance monitoring eliminates the need for patients to make frequent in-person visits to healthcare practitioners or rush to the hospital in case of an issue. Instead, patients may need to perform specific regular tasks at home and report the results to their doctor. For instance, they might be required to measure their blood pressure, monitor their weight, and complete a brief questionnaire every week, with the data being sent to their doctor. One patient, Jean-Louis Bernard, aged 74 from Caen, shared his experience with Le Monde, stating, "When you have a chronic illness, your condition can rapidly deteriorate, and if you're not careful, you may end up in the emergency room, even after consuming a meal that's too salty. Thanks to this tool, medical teams can respond to even the slightest alert and advise me remotely." His wife, Michelle, emphasized the invaluable assistance provided by remote monitoring, as it has prevented Jean-Louis from being hospitalized since he started using it, whereas hospitalizations were previously frequent. Why has reimbursement been extended to all individuals in need? The decision to make remote monitoring reimbursements accessible to all aims to achieve the following objectives: - Enhance the quality of care for patients undergoing distance monitoring. - Reduce hospitalizations and emergency room admissions by enabling patients to receive care at home. - Update healthcare processes and enhance care organization. - Improve patients' quality of life and overall comfort. Which conditions are eligible for distance monitoring? Since 2014, remote medical monitoring has been covered on an experimental basis under the ETAPES program (Experiments de télémédecine pour l'amélioration des parcours en santé) for the following five conditions: - Chronic respiratory failure - Chronic heart failure - Chronic renal failure - Diabetes Cardiac arrhythmia requiring cardiac prostheses The ETAPES program has now concluded, and distance monitoring can be implemented for any patients whose healthcare professionals determine the necessity, particularly for those who are at risk of hospitalization or health complications. The Ministry of Health has emphasized that patients must be fully informed about the process and provide their consent for monitoring. Which healthcare professionals can offer télésurveillance? According to Assurance Maladie, any doctor can refer a patient for remote monitoring. However, only healthcare professionals "whose specialities are referred to in the ministerial decrees registering telemonitoring activities, whatever their sector of practice and their place of practice” are authorized to carry out remote medical monitoring. These professionals can operate from general practitioner surgeries, nursing homes, health centers, hospitals, or clinics. *Photo by John Valette via Pexels

In the ever-evolving landscape of healthcare, telehealth has emerged as a transformative force, changing the way patients receive care. Coupled with wearable devices, telehealth offers a powerful combination that empowers patients to actively engage in their own self-care. This article explores the intersection of telehealth and wearable devices, highlighting their impact on patient engagement, monitoring, and overall healthcare outcomes. The Rise of Wearable Devices Wearable devices, such as fitness trackers, smartwatches, and medical wearables, have gained significant popularity among consumers. These devices provide continuous monitoring, real-time data collection, and insights into individual health metrics. They have increasingly found integration into telehealth settings, allowing for remote patient monitoring and personalized healthcare delivery. While wearable devices offer numerous benefits for patients in self-care, challenges related to data accuracy, device interoperability, and user adoption must be addressed to fully harness their potential. Telehealth and Remote Patient Monitoring Telehealth platforms seamlessly incorporate wearable device data for remote patient monitoring. This integration enables healthcare providers to remotely monitor patients' health metrics and vital signs in real-time. Continuous data collection and analysis through wearable devices facilitate proactive interventions, allowing for improved chronic disease management and preventive care. Real-life case studies have demonstrated the successful integration of wearable devices into telehealth programs, showcasing positive patient outcomes and enhanced healthcare experiences. Empowering Patients through Self-Monitoring Wearable devices play a pivotal role in encouraging self-monitoring and promoting healthy behaviors among patients. By providing real-time feedback on physical activity, sleep quality, and other health metrics, wearable devices motivate individuals to engage in regular exercise, maintain good sleep hygiene, and adopt healthier lifestyles. Patients can track a wide range of health parameters, including physical activity levels, sleep patterns, heart rate, and blood pressure. Furthermore, wearable devices leverage gamification elements and personalized feedback to enhance patient motivation and engagement, resulting in improved self-care adherence and long-term engagement. Enhancing Chronic Disease Management Wearable devices, when integrated with telehealth solutions, offer significant benefits for managing chronic conditions. For instance, continuous glucose monitoring (CGM) devices enable remote monitoring of patients with diabetes, facilitating timely adjustments in medication or lifestyle interventions. Wearable blood pressure monitors assist in managing hypertension, while smart inhalers help monitor asthma symptoms and medication usage. These devices also improve medication adherence through reminders and alerts, reducing the risk of complications. Continuous monitoring of health metrics allows healthcare providers to detect early signs of health deteriorations, enabling timely interventions and preventing adverse events. Promoting Healthy Lifestyles and Preventive Care Wearable devices act as powerful tools for promoting healthy lifestyles and preventive care. They track physical fitness, weight management, stress levels, and other factors contributing to overall well-being. Integration with telehealth platforms enables personalized health recommendations and interventions based on collected data. Wearable devices can facilitate early detection and prevention of diseases by continuously monitoring health metrics and analyzing trends. By empowering individuals to make positive lifestyle choices and adopt healthier habits, wearable devices contribute to proactive health management and reduce healthcare costs in the long run. Final Thoughts Telehealth and wearable devices have revolutionized patient self-care, offering a personalized and proactive approach to healthcare. By incorporating wearable devices into telehealth practices, patients have the means to actively engage in their health management. However, privacy, security, and ethical considerations must be prioritized to ensure responsible use of wearable devices in self-care. As technology continues to advance, the integration of telehealth and wearable devices holds immense potential to improve patient outcomes and transform the future of healthcare.

Following on from our post last week on what to expect during a physical examination, today’s blog will explain some of the laboratory and screening tests you may also undergo. Now it’s important to note that there are no standard laboratory or screening tests during a physical exam, so what you are advised to have will depend on your physician and health history. Laboratory tests during a physical exam The main laboratory tests you are likely to undergo during a physical exam are: – Complete blood count (CBC) – A CBC is a blood test that helps evaluate your overall health and detect a wide range of conditions, including anemia, infection and leukemia. – Chemistry panel – A comprehensive metabolic panel (CMP) will include an electrolyte panel (which measures levels of sodium, chloride, potassium and bicarbonate), kidney function tests, liver function tests and also measures glucose and calcium. – Blood glucose – To look for signs of diabetes or pre-diabetes. – Urinalysis – Using a sample of your urine, this test can detect a range of conditions, including urinary tract infections, kidney disease and diabetes. – Fecalysis – A stool sample test (fecalysis) can detect certain conditions affecting your digestive tract, including parasites, viruses, bacteria, poor nutrient absorption and even cancer. Screening tests during a physical exam In addition to the laboratory tests outlined above, you may also undergo the following screening tests: For women: – Mammogram – A screening test for breast cancer, usually recommended for women 40 and over – Pap smear – A screening test for cervical cancer, usually recommended for women 21 and older For men: – Prostate exam – A digital rectal exam is the most common method used for physically checking your prostate, while a PSA test measures the level of prostate-specific antigen in your blood – both of which can flag early signs of prostate cancer. – Testicular exam – A physical exam that checks both testicles for signs of abnormality, including lumps, changes in size, and tenderness. – Abdominal Aortic Aneurysm (AAA) screening – This simple ultrasound looks for a bulge or swelling in the aorta, and is usually recommended for men 65 and over, as they are most at risk. Both men and women: – Cholesterol test – Also called a ‘lipid panel’, this checks your cholesterol levels to see if you are at risk of heart attack or stroke. – Osteoporosis - A bone density scan can help reveal potential issues relating to weak bones. – Hepatitis – Everyone should be tested for hepatitis C at least once to find out if they have ever been infected with the virus. – Colorectal – A colonoscopy is usually used to check for colorectal cancer and other abnormalities in your colon. If you are a smoker, or have a family history of certain conditions, your physician may also recommend further tests in addition to those above. * Image by Ernesto Eslava from Pixabay

Over 400 million people worldwide are living with type 2 diabetes, according to the World Health Organization. Yet a new study suggests the condition could be controlled and even prevented through diet alone. Publishing their findings in the journal JAMA Network Open, researchers from Tulane University in Louisiana in the United States revealed how following a diet that is low in carbohydrates can help people with unmedicated diabetes and those at risk for diabetes lower their blood sugar. For the study, the researchers recruited 150 participants and separated them into two groups: one which followed a low carb diet (less than 40 net grams of carbohydrates a day for the first 3 months and less than 60 net grams during months 3 to 6) and one which followed their usual diet. The researchers found that not only did the low carb diet group see their hemoglobin A1c, a marker for blood sugar levels, drop, they also lost weight and had lower fasting glucose levels. “The key message is that a low-carbohydrate diet, if maintained, might be a useful approach for preventing and treating Type 2 diabetes, though more research is needed,” said lead author Kirsten Dorans, assistant professor of epidemiology at Tulane University School of Public Health and Tropical Medicine. *Image by Nemanja_us from Pixabay

Artificial sweeteners are often the go-to choice for people wishing to lose weight, but new research suggests they may increase the risk of cardiovascular disease. According to the study, the results of which are published in the BMJ, artificial sweeteners are associated with a 9 percent higher risk of any type of cardiovascular disease event and an 18 percent increased chance of stroke. “Our results indicate that these food additives, consumed daily by millions of people and present in thousands of foods and beverages, should not be considered a healthy and safe alternative to sugar,” the study authors wrote in The BMJ. Moreover, different sweeteners carried different risk. For example, aspartame, sold under the brand names NutraSweet and Equal, was tied to a 17 percent increased risk of stroke. Acesulfame potassium, sold under the brand names Sweet One and Sunett, was linked to a 40 percent higher risk of coronary heart disease. For the study, more than 100,000 adults (mostly female) were followed for around a decade, making it the largest to date to investigate cardiovascular health problems associated with sugar substitutes. At the start of the study, none of the participants had a history of cardiovascular disease or diabetes — and none of them were diagnosed with these conditions during the first two years of follow-up. *Image by designfoto from Pixabay

Taking a short walk after eating can help lower the risk of type-2 diabetes and heart problems, a new study suggests. According to the study, published in Sports Medicine, just 2 to 5 minutes of light walking after a meal can reduce blood sugar and insulin levels. Blood glucose levels spike after eating, triggering the pancreas to release insulin to control the increase and promote the storage of glucose in fat, muscle, liver and other body tissues. Over time, some people's cells develop a resistance to insulin, which can lead to blood glucose levels remaining elevated. If this persists, complications, including cardiovascular disease and nerve damage, can occur. “With standing and walking, there are contractions of your muscles” that use glucose and lower blood sugar levels, Aidan Buffey, the lead study author and a PhD student in physical education and sport sciences at the University of Limerick, told The Times. “If you can do physical activity before the glucose peak, typically 60 to 90 minutes [after eating], that is when you’re going to have the benefit of not having the glucose spike,” he said. *Image by

The American Heart Association (AHA) has added sleep to its cardiovascular health checklist for the first time. Sleep now joins diet, exercise, tobacco use, weight, cholesterol, blood sugar levels and blood pressure on the association's list of factors people can modify to stay healthy. The AHA published its new checklist, called “Life’s Essential 8,” in the journal Circulation on June 29. The old checklist, created in 2010, was known as “Life’s Simple 7.” “Not only is sleep health related to the other things that play a role in heart health, it seems to also be directly related to cardiovascular health itself,” says Michael Grandner, PhD, the director of the sleep and health research program at the University of Arizona College of Medicine in Tucson, who helped compile the new AHA checklist. “Sleep is changeable, and studies show that you can improve aspects of heart health just by improving sleep,” Dr. Grandner says. People who get less than six hours of good quality sleep a night are at increased risk of obesity, high blood pressure and type 2 diabetes, as well as worse mental and cognitive health, Grandner says. Likewise, those who get more than nine hours of sleep a night are also less likely to be healthy and more likely to die prematurely, he added. *Image by Wokandapix from Pixabay

Kids who are physically active stand a greater chance of remaining mentally sharp for decades, new research suggests. The finding adds to the weight of evidence in favour of kids being physically active, such as the associated bone and muscle development benefits and reduced risk of diabetes and heart attack. The study by researchers in Australia followed 1,200 people for 30 years. It uncovered a link between childhood fitness and mental performance in middle age. Commencing in 1985, the study assessed the heart and lung fitness, power, and endurance, and measured for waist-to-hip ratio of children between the ages of 7 and 15 at the time. More than 30 years later, those with the highest fitness scores and lower waist-to-hip ratios as kids tended to score better in tests of their thinking skills. Interestingly, while physical exercise was associated with higher scores in things like processing speed and attention, it had no impact on memory. Michele Callisaya, PhD, a study co-author and associate professor from the National Centre for Healthy Ageing at Peninsula Health and Monash University in Melbourne, Australia, said: “This might be because the cognitive functions of processing speed and attention start to decline in midlife. Memory generally starts to decline later.” The results of the study are published in the Journal of Science and Medicine in Sport. *Image by Tri Le from Pixabay

Coffee consumption is linked to numerous health benefits, including a reduced risk of type 2 diabetes, as well as liver, heart, and neurological diseases. Now, new research suggests we can also add kidney protection to that list. According to the study, the results of which are published in Kidney International Reports, people who regularly drink coffee have a reduced risk acute kidney injury. However, the benefits are most apparent in those who drink 2-3 cups of coffee each day. For the study, the team of researchers used data from 14,207 adults ages 45-64 from the Atherosclerosis Risk in Communities (ARIC) study. The researchers asked the participants to disclose information relating to how much coffee they drank. The results were: 27% never drank coffee 14% drank less than a cup of coffee per day 19% drank 1 cup per day 23% drank 2-3 cups per day 17% drank more than 3 cups per day After adjusting for demographic factors, the researchers found that participants who consumed any amount of coffee had an 11% lower risk of developing acute kidney injury than those who did not drink coffee. The researchers further noted a that those consuming 2-3 cups of coffee per day experienced the most substantial risk reduction (23%) *Image by Craig Melville from Pixabay

For people living with type 1 diabetes, finger prick tests to check blood glucose levels are a necessary part of daily life. Without them, these individuals could experience potentially life-threatening hypoglycaemic attacks, where their blood sugar levels fall too low. But regular finger prick tests could become a thing of the past for people with type 1 diabetes thanks to an artificial pancreas being trialled in England. The technology includes a sensor under the skin that monitors blood glucose levels, a pump that automatically adjusts the amount of insulin the person needs and a smartphone app where they can input the number of carbohydrates they eat at meal times. NHS England says the artificial pancreas trial – which currently involves around 900 people – is the first nationwide test of the technology in the world. It also comes 100 years after the first diabetes patient received insulin injections. Prof Partha Kar, NHS national speciality adviser for diabetes, said: "Having machines monitor and deliver medication for diabetes patients sounds quite sci-fi like, but technology and machines are part and parcel of how we live our lives every day. "It is not very far away from the holy grail of a fully automated system, where people with type 1 diabetes can get on with their lives without worrying about glucose levels or medication." *Image by Steve Buissinne from Pixabay

Staying "well hydrated" in middle age may lower a person's risk of heart failure in later life, new research suggests. According to the study by researchers at the Laboratory of Cardiovascular Regenerative Medicine at the National Heart, Lung, and Blood Institute (NHLBI), individuals with lower blood sodium levels (serum sodium) has a 39% lower risk of having heart failure in their later years. Serum sodium increases as a person's fluid levels decrease i.e. people who are dehydrated usually have more sodium in their blood. The normal range for serum sodium is 135 to 146 millimoles per liter (mmol/L). The researchers found that study participants with levels of serum sodium on the high end of the normal range — above 143 mmol/L — had a 39% increased risk of developing heart failure. For the study, the researchers analyzed information from more than 11,000 adults aged 45 to 66 over a 25-year period. It is worth noting that the study did not include individuals with diabetes, obesity or heart failure. The results of the study are published in the European Heart Journal. *Image by Engin Akyurt from Pixabay

Sugar-free and low sugar drinks can help people realise a number of health benefits, a new study has found. According to the research, the results of which are published in JAMA Network Open, drinking diet soda and sugar alternatives, such as Stevia and Equal, instead of can help people lose weight, reduce their BMI, and lower their risk of diabetes. In fact, the researchers said participants who consumed low and no-calorie beverages saw positive effects similar to those one would expect from water. “Ideally, you would replace sugary beverages with water as much as possible, but our findings show that people have another choice — a low-calorie or no-calorie beverage is a good option as well,” said Tauseef Ahmad Khan, MBBS, PhD, a researcher at the University of Toronto department of nutritional sciences and a coauthor of the study. Modern Western diets often contain too much sugar and it's causing a huge health problem. For example, the average American consumes 22 teaspoons (tsp) of added sugar daily, according to the Harvard T.H. Chan School of Public Health. The American Heart Association (AHA) recommends people limit their daily intake of sugar to about 6 tsp women and 9 tsp for men. Harvard T.H. Chan School of Public Health, lists higher blood pressure, inflammation, weight gain, diabetes, and fatty liver disease among the health issues related to too much sugar intake. *Image by DesignDraw DesignDrawArtes from Pixabay

Sleeping with even a small amount of light may disrupt your blood sugar and cardiovascular control, new research suggests. According to the study by scientists at Northwestern University Feinberg School of Medicine in Chicago, leaving a TV or bedside lamp on overnight is enough to the raise blood sugar and heart rates of healthy people. For the study – the results of which are published in Proceedings of the National Academy of Sciences – 20 healthy volunteers were asked to spend two nights in the university's sleep lab. On the first night, all participants slept in a very dark room. On the second, half slept with a lighting level of 100 lux, equivalent to a TV or bedside light. Each morning, the research team investigated all the volunteers’ blood sugar control. They found that people who slept in the dimly lit room on their second night had slightly worse blood sugar control than on their first night. “They thought they slept well, but your brain knows that the lights are on,” said Senior study author Dr Phyllis Zee, chief of sleep medicine at Northwestern University Feinberg School of Medicine. People who had two nights under dark conditions had little difference in their blood sugar control. Zee added: “The results from this study demonstrate that just a single night of exposure to moderate room lighting during sleep can impair glucose and cardiovascular regulation, which are risk factors for heart disease, diabetes and metabolic syndrome.” *Image by StockSnap from Pixabay

Magnesium is an essential macromineral, which means we all need to consume relatively large amounts of it to stay healthy. According to the Harvard T.H. Chan School of Public Health, the recommended daily amount of magnesium adults 19-51+ years should consume is 400-420 mg daily for men and 310-320 mg for women. Almonds, cashews, peanuts and spinach are all good sources of magnesium. But walnuts are even more magnesium-rich, providing around 158mg of the macromineral per 100g. Consuming enough magnesium in your diet is linked with a number of health benefits, including healthy bones, lower type 2 diabetes risk and better cardiovascular health. Magnesium is also linked to improved muscle contraction and nerve transmission, as well as better regulated blood pressure and boosted immunity. Previous research has shown that mice on a low-magnesium diet experience faster rates of cancer spread. Furthermore, said mice have weaker immune defenses against influenza viruses. Now, Swiss scientists have discovered that a type of immune cell, called a cytotoxic or “killer” T cell, need magnesium to do their jobs and eliminate cancerous or infected cells. The researchers discovered that magnesium activates a protein called LFA-1 on the surface of cytotoxic T cells, which they use to lock on to their targets. Senior author Dr. Christoph Hess, Ph.D., from the University of Basel in Switzerland and the University of Cambridge in the United Kingdom, explains: “In the inactive state, this docking site is in a bent conformation and thus cannot efficiently bind to infected or abnormal cells.” “If magnesium is present in sufficient quantities in the vicinity of the T cells, it binds to LFA-1 and ensures that it remains in an extended — and therefore active — position.” The researchers also found, through analyzing data from past clinical trials of cancer immunotherapies, that low serum levels of magnesium were associated with more rapid disease progression and shorter survival. The Swiss study appears in the journal Cell. *image by Pera Detlic from Pixabay

Telehealth has helped patients living with chronic conditions, such as type 1 diabetes, continue their care management throughout the pandemic, new research shows. According to the global survey of patients living with type 1 diabetes, many moved to telehealth because in-person doctor visits were curtailed as a result of COVID lockdown restrictions. But even after the pandemic has passed, three-quarters say they will continue to take advantage of telehealth solutions to meet their care management needs. The information, presented this week at the Annual Meeting of the European Association for the Study of Diabetes (EASD), highlights the value of telehealth platforms in maintaining care management during times of unprecedented disruption to daily life. Furthermore, many patients with chronic conditions will have foregone check-ups throughout the pandemic for fear of becoming infected or adding an extra burden to healthcare providers. Telehealth has a significant role to play hear by helping these individuals re-establish their care routines and get the treatment they require. The study conducted by researchers at the University of Bern in Switzerland and supported by Novo Nordisk, involving more than 7,000 people in 89 countries, is published in in the journal Endocrinology, Diabetes & Metabolism. “The results … demonstrate that a large number of people living with type 1 diabetes have rapidly adopted telemedicine or plan to in the near future and that this has generally been perceived positively,” the researchers concluded in the study.

Residents of Milam County, Texas, who saw the only two hospitals in their county close in 2018, will soon be able to take advantage of an unattended telehealth station. The $200,000 OnMed station is part of a $10 million grant from Blue Shield of Texas to A&M University to address the rural area's healthcare needs. With a large touchscreen, thermal camera, weight scale, stethoscope, and handheld camera, the telehealth station is capable of checking several aspects of a patient’s health. Furthermore, with a quick press of the touchscreen, patients are connected to a healthcare professional more than a thousand miles away, at the Tampa headquarters of OnMed. The professional, usually either a nursing assistant or nurse practitioner, is able to talk the patient through undertaking some basic checks, including blood pressure, respiratory readings, and blood oxygen saturation. There is even a dispensary attached to the booth which enables patients to get meds like common antibiotics, blood pressure, and diabetes medication instantly. At the end of each teleconsultation, an ultraviolet sanitizes all of the surfaces and equipment inside the booth ready for the next patient. Residents of Milam County will initially be able to use the telehealth station for two years, after which time a decision will be made on its future. Patients with or without insurance can take advantage of the telehealth station for as little as $45 to $65 per consultation. OnMed is also working with Auburn and Tuskegee with a view to placing stations in rural Alabama. CEO Austin White expects as many as 15 stations to be in operation across the country by the end of the year. *Main image credit: OnMed

With the number of confirmed coronavirus cases now topping 4 million globally, the urgency to develop a vaccine has never been greater. Now something that’s been witnessed throughout this pandemic is the way COVID-19 seems to hit some people harder than others. Whether a COVID-19 patient is hospitalized and requires more serious medical interventions, like ventilation, often depends on several risk factors. Age In the United States, 8 out of 10 COVID-19 deaths have occurred in patients aged 65 and older. The reason for this is thought to be because elderly individuals have more chronic medical conditions, such as heart disease and diabetes. Diabetes A recent meta-analysis of 13 separate studies found that people with diabetes were nearly 3.7 times more likely to have a critical case of COVID-19 or to die from the disease than patients without any underlying health conditions. Heart disease and hypertension The American Heart Association says people with cardiovascular issues, including heart disease and hypertension, generally tend to suffer worse COVID-19 complications than those with no pre-existing conditions. Smoking A study from China found that 12.3% of current smokers were admitted to an ICU, were placed on a ventilator or died. This compares to 4.7% of non-smokers. Obesity Being obese has been linked to an increased severity of COVID-19 in younger patients. Furthermore, a separate study from China – which has not yet been peer-reviewed – found that obese individuals were more than twice as likely to develop severe pneumonia as compared with patients who were normal weight.

It’s a well-known fact that sleep is of utmost importance to health. Specifically, it’s been shown that a lack of high-quality sleep negatively impacts our resilience, productivity and performance. Furthermore, long-term chronic sleep deprivation is linked to high blood pressure, diabetes, heart attack, heart failure and stroke. Now, new research suggests that irregular sleeping patterns may contribute to the risk of cardiovascular problems. The study was carried out by researchers from Brigham and Women’s Hospital in Boston, MA, who analysed data from 1,992 patients in their 60s and 70s with no cardiovascular problems at baseline. They found that those who had the most irregular sleep patterns (defined as 2 hours or more difference in sleep duration each night) had a twofold plus increased risk of cardiovascular disease than patients with one hour or less difference in sleep duration. Importantly, even after adjusting for other risk factors, patients with irregular sleep patterns remained at significant risk of cardiovascular events. Publishing their findings in the Journal of the American College of Cardiology, the researchers said: “Our study indicates that healthy sleep isn’t just about quantity but also about variability and that this can have an important effect on heart health.” Do you get enough sleep each night? Is your sleeping pattern pretty irregular? If not, you could be increasing your risk of cardiovascular disease. Remember, getting enough high-quality sleep is extremely important and beneficial to your health.

A new study has revealed five bad health habits which, if avoided, could help you live significantly longer. While the habits themselves are nothing we haven’t heard before, the findings of the study are important as they highlight just how much of an impact the five factors can have on lifespan. So if you want to live years longer, avoid these five behaviours: smoking, not exercising, being overweight, drinking too much alcohol and eating an unhealthy diet. Specifically, the study found that women aged 50 who avoided all five risk factors lived 14 years longer than women who did not. Among men, the difference in lifespan was 12 years. Publishing the study findings in the BMJ, senior author Dr. Frank Hu, who chairs the department of nutrition at Harvard T.H. Chan School of Public Health, said: “We found that following a healthy lifestyle can substantially extend the years a person lives disease-free.” Importantly, the results held true even after adjusting the data for age, ethnicity, family medical history and other potentially influential factors – emphasising that everyone stands to benefit from avoiding these five unhealthy habits. Finally, the research also revealed that the five habits had a positive impact for people diagnosed with a disease during the study period. For example, individuals who developed cancer lived an additional 23 years if they adopted four of the five healthy practices. In contrast, among those who didn't change, half only survived an additional 11 years. The same patterns were witnessed for both heart disease and diabetes.

The Mediterranean diet, which features plenty of vegetables, fruits, herbs, nuts, beans and whole grains, has long been lauded for its heart health benefits. But now a new study shows that it could also improve brain function in elderly people, even when only eaten for a year. According to the research published in the BMJ, following a Mediterranean diet for just 12 months can inhibit production of inflammatory chemicals in elderly individuals that can lead to loss of cognitive function, as well as prevent the development of chronic diseases such as diabetes, cancer and atherosclerosis. For the study, 612 elderly people from France, Italy, the Netherlands, Poland and the United Kingdom has their gut microbiome analysed. Then, 323 of them were put on a special diet, based on Mediterranean principles, for one year, while the rest were asked to eat as they normally would. After 12 months, all of the study participants had their gut microbiome re-analysed. Those who had followed the Mediterranean diet saw beneficial changes to the microbiome in their digestive system. The rate at which bacterial diversity was lost slowed and the production of potentially harmful inflammatory markers was reduced. Furthermore, there was also a growth of beneficial bacteria linked to improved memory and brain function. So-called “keystone” species, critical for a stable “gut ecosystem”, were also boosted, helping to slow signs of frailty, such as walking speed and hand grip strength. “Our findings support the feasibility of changing the habitual diet to modulate the gut microbiota which in turn has the potential to promote healthier aging,” the study authors said.

A compound found only in avocados could help reduce type 2 diabetes, new research suggests. The study by researchers from the University of Guelph in Canada found that a fat molecule called avocatin B, or AvoB - which avocados alone contain – can help strengthen insulin sensitivity and could forestall type 2 diabetes. Initial tests involving mice showed that AvoB slowed weight gain and increased insulin sensitivity by ensuring the complete oxidation of fats. As a result, mice that were given the compound had improved glucose tolerance and utilization. Then, in a separate, double-blind placebo‐controlled human trial, an AvoB supplement was given to people with an average Western diet for 60 days. The researchers found that the participants had tolerated the compound well and no negative effects in the liver, muscles, or kidneys were witnessed. There was also some weight loss among participants that took the supplement, though the authors of the study considered it statistically insignificant. Paul Spagnuolo, Ph.D., an associate professor at the University of Guelph, said the research team will now design clinical trials to assess AvoB's effectiveness in people. Furthermore, they have already received clearance from Health Canada to sell AvoB in powder and pill forms, perhaps as early as next year.

Type 2 diabetes is a chronic condition that occurs when a person’s body ineffectively uses insulin. It is the most common form of diabetes, accounting for 90% to 95% of the more than 30 million diabetes cases in America today. Despite rising numbers, it is estimated that around 80% of new type 2 diabetes diagnoses could be prevented with lifestyle changes and more education. But while it’s been known for some time that when added to a genetic predisposition, factors like being overweight and a lack of physical activity increase a person’s risk of developing type 2 diabetes, very little research has been done to determine the impact of other environmental factors. That’s why a new study by a team from the University of Illinois at Chicago (UIC) School of Public Health which set out to determine if type 2 diabetes risk changes between urban and rural environments is interesting. According to the research - which involved examining 3,134 people across the United States - the quality of the air, water, and land, as well as numerous sociodemographic factors, such as education, average household income, violent crime rates, or property crime rates has an impact on a person’s type 2 diabetes risk. So-called ‘built domain factors’ were also used. These included how many fast-food restaurants were in a particular area; how many fatal accidents occurred, and how many highways, roadways, or public housing units there were. The research found that a poorer environmental quality was linked with a higher prevalence of type 2 diabetes. Specifically, inferior air quality and built and sociodemographic factors were associated with a higher risk of diabetes in rural areas, while in urban areas, only air and sociodemographic factors were associated with diabetes risk. “There might be something happening in rural areas that is different than in urban areas. Our findings suggest that environmental exposures may be a bigger factor in rural counties than in urban areas in the U.S.,” explains Dr. Jyotsna Jagai, lead author.

Obesity is worryingly common across the world today. World Health Organization statistics from 2018 show that global obesity has almost tripled since 1975 and most of the world’s population now live in a country where being overweight or obese kills more people than being underweight. But while obesity is known to increase a person’s risk of certain health conditions, new research has revealed that it does not seemingly affect men and women in the same way. According to the study from Oxford University in the United Kingdom, the findings of which are summarized in the journal PLOS Genetics, the risks of developing different health problems as a result of being obese are different for men and women. For example, obese women are at higher risk of developing type-2 diabetes than men. Meanwhile, obese men have a higher risk of chronic kidney disease and chronic obstructive pulmonary disease. The team says their findings add to the existing evidence that preventing and treating obesity is a crucial step in countering the emergence of other health conditions. “This study shows just how harmful carrying excess weight can be to human health, and that women and men may experience different diseases as a result,” said first author Dr. Jenny Censin. For the study, the team from Oxford University analyzed genetic information and three different obesity measures in a cohort of 195,041 men and 228,466 women.

A new study has found that if people with type-2 diabetes achieve just 10% weight loss within 5 years of being diagnosed, they are twice as likely to experience remission at the 5-year follow-up as those who haven’t lost any weight. The findings of the study by researchers from Cambridge appear in the journal Diabetic Medicine and were obtained through analysis of 867 people aged 40-69 with newly diagnosed type-2 diabetes. Having followed the study participants for 5 years, the researchers found that 257 (30%) had diabetes in remission. Speaking about their findings, first author Hajira Dambha-Miller, Ph.D. said: “Our results suggest that it may be possible to get rid of diabetes, for at least 5 years, with a more modest weight loss of 10%. This will be more motivating and hence more achievable for many people.” The fact diabetes can be sent into remission with just moderate weight loss – and not just the drastic intensive weight loss measures we’ve known about for some time - will be welcome news for many people living with the condition. It reinforces the importance of managing one’s weight through dietary choices and physical exercise. Going forward, the Cambridge team hopes to be able to use the research to help medical professionals better support patients with type-2 diabetes and reduce their symptoms.

The method via which a baby is born has a dramatic impact on its gut bacteria and could explain why babies born by Caesarean section are more likely to experience health problems later in life, a new study has found. The study by Wellcome Sanger Institute, UCL, and the University of Birmingham – the largest of its kind – looked at babies’ microbiomes (the bacteria, viruses and fungi that live in our guts) to see if they formed differently depending on how a baby was born. For the research, samples were taken on a regular basis from the nappies of 600 babies in their first month of life. The results showed that vaginally born babies got most of their first bacteria from their mothers. However, babies born via Caesarean section showed high levels of hospital bugs, with some having as much as 30% of their total microbiomes made up by such bugs. It’s a reality that could explain why babies born by Caesarean section are more susceptible to certain conditions when they are older, like allergies, asthma and type 1 diabetes. Speaking about the findings of the research, Dr Trevor Lawley, from the Wellcome Sanger Institute, said: “What surprised me and scared me was the amount of healthcare bugs showing up in these children. “But what excites me is we have an amazing body of data now that we can build on, to think about how to properly establish the human ecosystem, starting at birth.”

Simple educational and motivational text messages can help people with diabetes manage their blood sugar better, a new study has found. It is not only an extremely affordable and scalable measure, but one that can be applied globally. According to the six-month Chinese study, diabetes patients who received the text messages and standard care reduced their glycated hemoglobin (HbA1c ) by more than patients who just received standard care. The results showed an average reduction in HbA1c of 2 mmol/mol (0.2%) in patients who received the supportive text messages. The group that did not receive the text messages experienced an average increase in HbA1c of 1 moll/mol (0.1%). For the study, the participants were split into two groups: one that received standard diabetes care and two text messages each month thanking them for their participation, and another group that received standard care and up to six text messages per week containing information on subjects like dietary advice, physical activity, emotional support and blood glucose monitoring. As well as actually reducing their HbA1c, the group receiving the supportive text messages also had a greater proportion of patients who achieved their HbA1C target of less than 7% (69.3% vs. 52.6% in the control group). Speaking about the findings of the study, Dr Xiqian Huo, of Beijing's Fuwai Hospital, said: “Lifestyle advice such as strict dietary control may have contributed to glycemic improvements, together with reminders to monitor blood glucose regularly. The messages were designed to provide information and motivation, and help patients set goals and manage stress.” The results of the study were presented at the annual meeting of the European Society of Cardiology on Saturday, August 31 also appear in journal Circulation: Cardiovascular Quality and Outcomes.

People with type-2 diabetes get no benefit from taking omega-3 fish oil supplements, a new study has found. According to researchers from the University of East Anglia, while omega-3 supplements are not harmful for people with type-2 diabetes (this has been a concern previously), they don’t provide any benefit either. This contradicts a common belief that omega-3 can protect against diabetes and even reverse the condition. The study, which involved 58,000 participants, found that people who consumed more omega-3 had the same risk of developing diabetes as individuals who did not. Furthermore, taking omega-3 fish oil did not influence levels of blood glucose, insulin and glycated haemoglobin - all measures of how the body handles sugar. ‘Better to eat fish’ Douglas Twenefour, deputy head of care at Diabetes UK, said: “Eating a healthy, varied diet is incredibly important, and we know that certain foods - including fruits, vegetables, wholegrains, yoghurt and cheese - can help to lower your risk of type 2 diabetes. “While omega-3 fatty acids are crucial for our overall health, it's generally better for people with type 2 diabetes to get their intake by eating at least two portions of oily fish a week, than by taking supplements." The advice from Dr Lee Hooper, who led the research, is to forego the expensive omega-3 supplements and instead buy oily fish and/or spend your money on physical activity, which will have more of a positive impact when it comes to type-2 diabetes.

Postmenopausal women who have more fat on their legs and thighs have less risk of stroke or heart disease than their peers who carry fat around their stomach, a new study has found. As a result of the research, the findings of which appear in the European Heart Journal, scientists say women should aim to be more “pear-shaped” than “apple-shaped”. For the research, scientists followed 2,600 women with BMIs of between 187 and 25 for 18 years. The scientists found that the women who were apple-shaped i.e. had fat around their stomachs were more than three times more likely to develop cardiovascular disease than the women who were pear-shaped i.e. had fat on their legs and thighs. It’s already known that fat stored in the visceral region (around the abdominal organs) can increase a person’s chances of developing type-2 diabetes and cardiovascular problems, but the exact reasons why remain unknown. Further research is needed. The advice for women (and men) is to reduce the amount of fat they have stored around their stomachs. Speaking about the findings of the study, Dr Sonya Babu-Narayan, associate medical director at the British Heart Foundation, said: “This study uncovers an interesting link between where fat is stored and your risk of heart attack and stroke, but can't tell us why it exists. “Future research to uncover how the distribution of body fat is related to these diseases could reveal important new ways to prevent and treat the world's biggest killer.”

A major study has found that the UK has a big obesity problem, and that there are severe health implications for people who are even just a little overweight. According to the research, which was funded by healthcare firm Novo Nordisk, individuals with a Body Mass Index (BMI) of 30-35 were 70% more likely to develop heart failure than their healthy weight peers (18.5-25 BMI). Furthermore, the study of 2.8 million adults also showed that people who were even slightly overweight were twice as likely to develop Type 2 diabetes. The study, which is due to be presented at the European Congress on Obesity (ECO) in Glasgow, also revealed: The risk of Type 2 diabetes for people with a BMI of 35-40 was almost nine times higher People with severe obesity (BMI of 40-45) were 12 times more likely to develop Type 2 diabetes People with severe obesity also had triple the risk of heart failure, high blood pressure, and dyslipidaemia (elevated levels of total or low-density lipoprotein (LDL) cholesterol levels, or low levels of high-density lipoprotein (HDL) cholesterol) A BMI of 40-45 was also linked with a 50% higher risk of dying prematurely from any cause Speaking about the findings of the study, Public Health England said “sustained action” was needed to tackle obesity.

Following a low-calorie diet – even for just a few months – can arrest type-2 diabetes for at least two years, new research suggests. The findings of the study highlight that type-2 diabetes might not necessarily be the life sentence we previously thought. Nearly 300 people with type-2 diabetes in Scotland and Tyneside (in the UK) participated in the study. Half were given standard diabetes care, while the other half were put on a structured weight management programme. After 12 months, 46% of those on the low-calorie programme had successfully reversed their type-2 diabetes. In comparison, just 4% of the study participants given the standard treatment had gone into remission. Two years later, 36% of the study participants on the structured weight management programme were still in remission. “People with type 2 diabetes and healthcare professionals have told us their top research priority is: ‘Can the condition be reversed or cured?’ We can now say, with respect to reversal, that yes it can. Now we must focus on helping people maintain their weight loss and stay in remission for life,” said Prof Mike Lean from Glasgow University, who led the study with Taylor. Type-2 diabetes causes blood sugar levels to rise and can lead to serious complications such as amputations, visual problems and heart disease. It is thought that one in 16 adults in the UK is currently living with type-2 diabetes, a condition that is fuelled by obesity. [Related reading: Why being overweight increases your risk of cancer]

A new study has revealed that half of UK adults cannot name a single dementia risk factor. If asked, how many could you name? The study by Alzheimer's Research UK found that just 1% of UK adults could name the seven known dementia risk or protective factors. Heavy drinking, smoking, genetics, high blood pressure, depression and diabetes are the six dementia risk factors, while physical exercise is a protective factor. According to the study, more than half of UK adults know someone with dementia, yet only half also recognised that the disease is a cause of death. Furthermore, a fifth of people quizzed for the report incorrectly said that dementia is an inevitable part of getting old. Right now, there are more than 850,000 people in the UK living with dementia and that number is expected to top one million by 2025. Alzheimer's disease is the most common type of dementia, accounting for around two-thirds of all cases. Hilary Evans, chief executive of Alzheimer’s Research UK, said: “It is a sad truth that more people are affected by dementia than ever before and half of us now know someone with the condition. Yet despite growing dementia awareness, we must work harder to improve understanding of the diseases that cause it.” You can read the full Alzheimer’s Research UK report here: https://www.dementiastatistics.org/wp-content/uploads/2019/02/Dementia-Attitudes-Monitor-Wave-1-Report.pdf#zoom=100

People who have sedentary jobs could significantly boost their lifespans by taking short, regular movement breaks, a new study has found. It’s no secret that individuals who spend a lot of time sitting down are more likely to develop certain adverse health conditions, such as diabetes, obesity and cardiovascular diseases, as well as having increased risk of osteoporosis, depression, anxiety, colon cancer and high blood pressure. However, just a small amount of exercise, the study suggests, could lower the risk of early death. According to the research – the findings of which are published in the Annals of Internal Medicine – individuals who sat for less than 30 minutes at a time had the lowest risk of early death. For example, workers who had a movement break (involving some low-intensity exercise) every 30 minutes had a 17% lower risk of death than their counterparts who did not have any breaks. Moreover, individuals who broke up periods of sitting every 30 minutes with moderate- to high-intensity exercise lowered their risk of early death by 35%. Speaking about the findings of the research, Keith Diaz, an assistant professor of behavioural medicine at Columbia University Vagelos College of Physicians and Surgeons in New York City and study lead, said: “If you have a job or lifestyle that involves a lot of sitting, you can lower your risk of early death by moving more often, for as long as you want and as your ability allows — whether that means taking an hour-long high-intensity spin class or choosing lower-intensity activities, like walking.”

The health benefits of eating fiber have long been hailed, but how much fiber should we all be eating to prevent chronic disease and premature death? A new study reveals just that… Commissioned by the World Health Organization (WHO), the research is the culmination of a meta-analysis of observational studies and clinical trials that took place over almost 40 years. The results appear in the journal The Lancet. One of the objectives of the research was to help in the development of new guidelines for dietary fiber consumption, as well as discover which carbs protect us the most against noncommunicable diseases. So how much fiber should we be eating? Well, the research found that a daily intake of 25–29 grams of fiber is ideal. People who consumed this amount of fiber each day were 15–30 percent less likely to die prematurely from any cause and had a 16–24 percent lower incidence of stroke, coronary heart disease, type 2 diabetes, and colon cancer. The researchers also say that consuming more than 29 grams of fiber per day could lead to even more health benefits. Speaking about the findings of the study, Professor Jim Mann, of the University of Otago, in New Zealand, said: “The health benefits of fiber are supported by over 100 years of research into its chemistry, physical properties, physiology, and effects on metabolism. “Fiber-rich whole foods that require chewing and retain much of their structure in the gut increase satiety and help weight control and can favorably influence lipid and glucose levels. “The breakdown of fiber in the large bowel by the resident bacteria has additional wide-ranging effects including protection from colorectal cancer.” Fiber-rich foods include vegetables, whole grains, fruit, and pulses, such as beans, peas, lentils, and chickpeas. Are you consuming enough fiber?

According to the World Health Organization (WHO), obesity is a “global epidemic” that must be tackled if we are to prevent its ill effects. In the United States, nearly 40% of adults and 18.5% of children aged 2 to 19 are obese. Obesity is a major risk factor for type-2 diabetes, heart disease and some types of cancer. That’s why finding effective ways to treat the condition is paramount. But now scientists say they are on the verge of creating a pill that could make obesity a thing of the past - without the need for diet and exercise. Sounds too good to be true, right? Nevertheless, the team at Flinders University in South Australia say that they key to curbing obesity could lie in a single gene known as RCAN1. The team found that when RCAN1 was removed in mice and they were then fed a high fat diet, they did not gain weight. In fact, they could eat as much food as they wanted over a prolonged period of time, the researchers say. Damien Keating, Ph.D., professor of molecular and cellular physiology at Flinders, and leader of the research team, said blocking RCAN1 allows the body to transform unhealthy white fat into calorie-burning brown fat. Stunning pictures of the mice used for the trial highlight the difference when RCAN1 was blocked and when it wasn’t. The results of the research are published in the journal EMBO Reports.

A new study, one of the largest of its kind, suggests being the wrong weight i.e. overweight or underweight cold knock four years off a person’s life expectancy. According to the study, the findings of which were published in the Lancet Diabetes and Endocrinology journal, from the age of 40, people towards the higher end of the healthy Body Mass Index (BMI) range (a healthy BMI ranges from 18.5 to 25) had the lowest risk of dying from disease, including cancer and heart disease. In contrast, individuals who had BMI scores of less than 18.5 or more than 30 had life expectancies that were 4.4 years and 3.85 years shorter respectively. BMI scores, which are calculated by dividing a person’s weight (in kilograms) by their height (in metres squared), are still considered by health professionals to be the simplest and most accurate way to work out if someone is overweight or underweight. For the population-based cohort study, researchers analysed anonymised data on 3.6 million adults from the U.K. Clinical Practice Research Datalink (CPRD). Dr Krishnan Bhaskaran, lead author of the study, said: “The most striking thing about our findings was how widely BMI was linked to different causes of death. BMI was associated with deaths from nearly all major causes.” He added that the research reinforces the importance of maintaining a healthy body weight. Perhaps the most interesting finding is that people who have low BMI scores are at as much risk, if not more, of reducing their life expectancies.

The physical health problems associated with diabetes are well understood and publicised. For example, diabetics have an increased risk of developing cancer, kidney disorders and cardiovascular disease. But what about the mental impact of living with diabetes? It’s not something that gets a lot of attention, but the findings of a new study could see it thrust under the spotlight. That’s because the study by researchers from Finland found a worrying connection between diabetes and the risk of someone dying by suicide or alcoholism. According to the study, diabetics are more than 10 times more likely to die as a result of alcoholism – predominantly cirrhosis of the liver – and 110% more likely to commit suicide than the general population. The highest risk was seen among diabetes patients who rely on regular insulin injections to avoid serious health complications. Professor Leo Niskanen, of the University of Helsinki, who led the study, said diabetes patients who have to monitor their glucose levels and administer insulin frequently suffer tremendous mental strain. “This strain combined with the anxiety of developing serious complications like heart or kidney disease may also take their toll on psychological well-being,” he said. Is it time we started talking about the mental health implications of living with diabetes? [Related reading: Type-2 diabetes could actually be detected up to 20 years in advance, researchers say]

Some of the warning signs often associated with type-2 diabetes can be detected years before the disease is actually diagnosed, researchers say. A study found factors such as insulin resistance and elevated blood sugar levels were seen in people years prior to them developing pre-diabetes – a typical pre-cursor to the type-2 form of the disease. The authors of the Japanese study say their findings suggest that diabetes treatment should begin much earlier in life. For the study, conducted over an 11-year period, the researchers followed a group of 27,000 people who were not diabetic and aged between 30 and 50. The individuals were tracked until they either (a) got diagnosed with type-2 diabetes; (b) got diagnosed with pre-diabetes; or (c) the end of 2016 was reached. During the study, 1,067 new cases of type-2 diabetes were diagnosed. The interesting part is that these people showed warning signs, such as insulin resistance and higher fasting blood sugar levels, up to 10 years prior. Similar warning signs were also seen in those that went on to develop pre-diabetes. So, this suggests that type-2 diabetes could actually be detected up to 20 years before a diagnosis occurs. This is because people who develop type-2 diabetes usually get pre-diabetes first. Dr Hiroyuki Sagesaka, from Aizawa Hospital in Matsumoto, Japan, who led the research, said: “Because trials of prevention in people with pre-diabetes seem to be less successful over long-term follow-up, we may need to intervene much earlier than the pre-diabetes stage to prevent progression to full blown diabetes. “A much earlier intervention trail, either drug or lifestyle-related, is warranted.” [Related reading: Diabetes is actually five diseases, not two]

Have you ever received a letter from your doctor or physician and not been able to clearly understand its contents? If you have, we’ve got some positive news for you. That’s because the Academy of Medical Royal Colleges is urging doctors to do away with medical jargon in correspondence to patients and use easy to understand terms instead. For example, the academy says the term “twice daily” is much better than the often used Latin abbreviation “bd”, and says patients should ask their local hospital to follow the advice. Oftentimes, hospital doctors write letters directly to a patient’s GP and refer to the patient in the third person. However, this can lead to things being misinterpreted and even the patient being offended. The academy cites the example of a father who was praised for “manfully stepping in” when his wife could not take their daughter to an appointment because she (the wife) was too ill. Doctors are also being asked to try and soften potentially sensitive information and avoid stigmatising words. For example, “You have diabetes,” is better than “You are diabetic.” The initiative is being led by Dr Hugh Rayner, a kidney specialist, who has been writing to patients directly since 2005. He said: “The change may seem small but it has a big effect. “Writing to patients rather than about them changes the relationship between doctor and patient. “It involves them more in their care and leads to all sorts of benefits.”

Dans le monde, l’espérance de vie s’allonge, mais la mauvaise alimentation est responsable de près d’un décès sur 5. Bonne nouvelle : dans le monde, l’espérance de vie s’allonge et la mortalité infantile baisse, selon une étude coordonnée par l’Institut de mesure et d’évaluation de la santé à l’Université de Washington à Seattle (IHME), publiée vendredi, qui compile des données de 195 pays et territoires. L’étude a également exploré les causes de décès dans le monde. Allongement de la durée de vie En un demi-siècle, l’espérance de vie moyenne tous sexes confondus a augmenté de 14 ans: elle est aujourd’hui de 72,5 ans (75,3 ans chez les femmes, et 69,8 ans chez les hommes), contre 58,4 ans en 1970. C’est le Japon qui détient le record de l’espérance de vie moyenne la plus élevée, 83,9 ans pour les deux sexes combinés. La Centrafrique a la plus basse, 50,2 ans en moyenne. «Les gens vivent plus longtemps», se réjouit le Dr Christopher Murray, directeur de l’IHME. Il ajoute avoir constaté avec ses collègues au cours de la dernière décennie des «progrès importants», comme la baisse de la mortalité infantile et du paludisme. En effet, les décès d’enfants de moins de 5 ans sont passés pour la première fois en dessous de 5 millions en 2016, trois fois moins qu’il y a 50 ans (16,4 millions en 1970). Un décès sur cinq dans le monde serait lié à une mauvaise alimentation De nombreuses données de l’étude pointent toutefois les problèmes liés au mode de vie, en particulier à une mauvaise alimentation. Sur les 54,7 millions de décès constatés en 2016 dans le monde, 72% sont causés par des maladies non transmissibles (affections cardiovasculaires, diabète) souvent liées au mode de vie: alimentation, sédentarité, tabac, alcool, etc. Près d’un décès sur cinq serait provoqué par une mauvaise alimentation, en particulier celle pauvre en céréales complètes, fruits et légumes, noix et poissons. Les auteurs soulignent que parmi toutes les formes de malnutrition, les mauvaises habitudes alimentaires représentent le principal risque de mortalité. L’alimentation trop salée est par exemple associée à un peu plus de dix millions de décès (18,8%) dans le monde. Il n’est donc pas étonnant que parmi les dix principaux facteurs de risque de décès on retrouve l’obésité, un excès de cholestérol sanguin, et une glycémie (taux de sucre dans le sang) et une pression artérielle élevées. Le tabac est lui responsable d’un peu plus de 7 millions de décès.

It’s thought around one in 100 babies has genes that place them at increased risk of developing type 1, insulin-dependent diabetes. And unfortunately, at present, there is no way to prevent type 1 diabetes. But experts believe a new technique may be able to prevent high-risk babies from developing the condition. The idea is to use powdered insulin to train the immune systems of infants so that they are afforded life-long protection. Pregnant women attending maternity check-ups in Berkshire, Buckinghamshire, Milton Keynes and Oxfordshire in the UK are being asked to take part in the trial. Trial participants will be split into two groups, with half getting real insulin and the other half a placebo. Neither the participants nor the researchers will know which they received until after the trial. By spoon-feeding an infant insulin powder from six months to three years, experts hope their immune systems will be trained to tolerate insulin and prevent type 1 diabetes. A lifelong condition, type 1 diabetes is an autoimmune disease which causes insulin-producing cells in the pancreas to be destroyed. As a result, the pancreas doesn’t produce any insulin and the person's blood sugar (glucose) level becomes too high. Speaking about the trial, Dr Elizabeth Robertson, director of research at Diabetes UK, said: "This is a huge endeavour, so we would encourage women living in the South East who think they might be eligible to find out more - research like this can't happen without the incredible people who take part."
