  • Eyes Could Reveal Heart Attack Risk

    Deep learning applied to a retinal fundus image, a photograph that includes the blood vessels of the eye, can predict risk factors for heart diseases.

     

    Knowing the risk of a heart attack or a stroke could soon become as simple as an eye test as researchers at Google and its health-tech arm Verily have found that Artificial Intelligence (AI) and Machine Learning (ML) could help identify signals of heart diseases through retinal images.

     

    “AI offers us the potential for new, less invasive tests for heart health – predicting cardiovascular results from retinal images with computer vision – encouraging early results!,” Google CEO Sundar Pichai said on Tuesday while referring the study in a tweet.

     

    The study, published in the journal Nature Biomedical Engineering, showed that deep learning applied to a retinal fundus image, a photograph that includes the blood vessels of the eye, can predict risk factors for heart diseases – from blood pressure to smoking status.

     

    The algorithm that the researchers produced can even help predict the occurrence of a future major cardiovascular event on par with current measures, said Michael McConnell, head of Cardiovascular Health Innovations at Verily in a blog post.

  • Try Standing, You Could Live Longer

     

    By standing for sitting for six hours a day, a 143.3-pound adult would expend an extra 54 calories (kcals) in six hours.

     

    Struggling to lose weight but are too lazy to hit a gym or follow a strict diet? Try standing instead of sitting for six hours a day as it may help you shed that extra kilos over a long term, finds a study. The researchers found that standing burned 0.15 calories (kcals) per minute more than sitting.

     

    By substituting standing for sitting for six hours a day, a 143.3-pound adult would expend an extra 54 calories (kcals) in six hours. “Standing not only burns more calories, the additional muscle activity is linked to lower rates of heart attacks, strokes and diabetes. So the benefits of standing could go beyond weight control,” said Francisco Lopez-Jimenez, Professor at the Mayo Clinic in Rochester, a US-based non-profit.

     

    Importantly, calories burned between standing and sitting is about twice as high in men as in women. This likely reflects the effect of greater muscle mass in men on the amount of calories burned because calories burned is proportional to the muscle mass activated while standing, researchers noted.

     

    “It’s important to avoid sitting for hours at a time. Standing for long periods of time for many adults may seem unmanageable, especially those who have desk jobs, but, for the person who sits for 12 hours a day, cutting sitting time to half would give great benefits,” Lopez-Jimenez added. In the new study, published in the European Journal of Preventive Cardiology, the team analysed 46 studies with 1,184 participants.

  • Recurring Headaches? Talk To Your Doctor About Migraine Remedies

     

    Patients often treat migraine as a regular headache and it remains undiagnosed and under-treated.

     

    Most migraine sufferers know little or nothing about what triggers their pain. It is a condition neglected by many, who fail to recognise it as a neurological disorder.

     

    Patients often treat migraine as a regular headache and it remains undiagnosed and under-treated.

     

    The most frequently mentioned triggers among migraineurs in the UAE include increased screen time, stress, consuming salty and processed foods, use of additives, irregular sleep pattern and physical exertions, among others. In women, hormonal changes and the use of medication for hormonal replacement therapy can cause and worsen the condition.

     

    The global Migraine Awareness Week (MAW), which starts today until September 7, educates people on reading symptoms of migraine and not to neglect it as recurring headaches.

     

    “The most effective way to treat migraine is a combination of medicine and lifestyle changes. The doctor may prescribe pain-relieving medication or preventive medication, depending on the condition. We have also seen breakthrough developments with new highly effective medicines which can control migraine, exhibiting good results and excellent cure,” said Dr Vivek Karan, head of neurology department at the RAK Hospital.

     

    Doctors advise that it is important to observe signs and symptoms of recurring headaches, keep a record of your attacks and seek medical help to discuss headaches.

     

    Patients are strongly advised against any self-medication, particularly without evaluation – since it can further complicate the condition.

     

    A dedicated website, mena.speakmigraine.com, managed by pharmaceutical brand Novartis, is actively helping patients in the UAE to keep the condition within their control. The app has a dedicated segment called ‘Migraine Buddy’ which helps users record and identify triggers, symptoms, frequency and duration, and pain intensity and location of their migraines, as well as other lifestyle factors and any medication that was taken.

     

    Migraine is a distinct neurological disease that involves recurrent attacks of head pain that may be pulsating, unilateral and associated with nausea, vomiting and sensitivity to light, sound and odours.

     

    “Migraine comprises about 20 per cent of chronic headaches worldwide. If you include other forms of primary headaches – Cluster Headache and Episodic and Chronic Tension-Type Headache – the incidence is even higher. Quite a lot of people suffer from what is called Chronic Daily Headache Syndrome – defined as having at least 15 headache days a month. If you relax this strict rule and include those who have 10 headache days a month, then you will probably include about 40 to 50 per cent of people in the UAE,” said Dr Rajshekher Garikapati, specialist neurologist, Aster Hospital, Mankhool.

     

    Migraine is a genetic condition which is fairly common in the UAE, probably more than the global average, according to Dr Garikapati. “I have seen migraine patients coming up with pages detailing various medicines and food items to be avoided. The thing to remember is that only about 20 per cent of migraineurs are thought to be food sensitive,” he said.

     

    Dr Garikapati advised patients to identify if any particular food consistently causes an attack within 20 minutes to two hours after eating it. “If foods have been highly cooked or mixed with various other items, then it is very difficult to be certain that it is a trigger. This is true with Indian, Filipino diets or even Chinese diets. Mediterranean diets may be simpler where the cooking is minimal .”
