Melbourne, Jun 11: Scientists have developed an app that uses a simulated digital nurse to teach patients how to recognise symptoms of heart attack and call emergency. Patients using the SAVE app are more likely to call an ambulance when they had symptoms and had fewer hospital admissions, researchers said.

“Most deaths from heart attacks occur within the first few hours of symptom onset,” said Jintana Tongpeth, a PhD student at Flinders University in Australia. “The death rate can be halved by getting patients to a hospital more quickly. Delays occur mainly because patients don’t recognise symptoms or know to call an ambulance,” said Tongpeth.

An avatar is a simulated digital character that interacts by talking and using facial expressions and body language. The SAVE app uses an avatar, a nurse named Cora, to teach heart attack warning signs and symptoms, and what to do when they occur. The app has four sections heart attack warning sign quiz; heart attack signs and symptoms, showing which symptoms are more common in men versus women; what to do when having a heart attack; heart attack warning signs test.

During the initial development phase, a pilot study in ten heart attack survivors found that using the app improved symptom recognition and knowledge about what to do. These results became the preliminary data for a larger, statistically powered randomised controlled trial.

On Monday, researchers present results of this first randomised controlled trial testing the impact of using the app on knowledge and response to heart attack symptoms. The trial randomly allocated 70 heart attack survivors to the app plus routine discharge information or routine discharge information alone (usual care group). App users received a tablet computer, with the app installed, to use at home for six months.

Knowledge of symptoms and appropriate responses was assessed in both groups at the start of the study and at six months. Ambulance use and hospitalisations during the six month period were recorded. When symptoms occurred, app users were significantly more likely to call an ambulance (89 per cent) compared to the usual care group (43 per cent).

During the six months, app users spent less time in a hospital for heart problems than patients in the usual care group (3.6 days versus 6.4 days on average, respectively). At the start of the study, patients in both groups had similar knowledge of heart attack symptoms and how to react. At six months, app users had significantly better knowledge of symptoms and how to react than those who received routine discharge information alone. Some 85 per cent of app users said Cora had increased their confidence in recognising heart attack symptoms and knowing how to react.

“Our study shows that patients using an avatar-based app are more likely to call emergency if they have heart attack symptoms and spend less time in hospital. A larger trial is needed to see if this translates into quicker treatment and increased survival,” said Tongpeth. “Nurses have limited time to provide discharge education and often encounter literacy and language barriers. This avatar app will be an essential tool to help overcome these difficulties. The pictures do not require patients to read, and we are translating the content so that Cora speaks 144 languages,” said Robyn Clark, a professor at Flinders University.

With the sales of chicken and mutton going down due to the coronavirus scare, it is the humble 'Kathal' (jackfruit) is emerging as an acceptable alternative.

'Kathal' is now selling at ₹120 per kilogram -- an increase of more than 120 per cent over the normal ₹50 per kilogram.

The jackfruit, in fact, is now priced higher than chicken which is selling at ₹80 per kilogram due to poor demand.

"It is better having a 'Kathal' biryani instead of a mutton biryani. It tastes reasonably good. The only problem is that 'Kathal' has been sold out in the vegetable market and is difficult to find," said Purnima Srivastava whose family savours non-vegetarian food on a regular basis.

The corona scare has hit poultry business so hard and the Poultry Farm Association recently organized a Chicken Mela in Gorakhpur to dispel the misconception that birds are carriers of the deadly virus.

"In fact, we gave away plateful of chicken dishes for Rs 30 to encourage people to savour the delicacies. We cooked one thousand kilograms of chicken for the Mela and the entire stock was sold out," said Vineet Singh, head of the Poultry Farm Association.

However, the Mela did not do much to dispel the fears about chicken, mutton or fish consumption amid the virus outbreak.

New Delhi, Jul 21: The Centre has written to all states and union territories warning against the use of N-95 masks with valved respirators by people, saying these do not prevent the virus from spreading out and are "detrimental" to the measures adopted for its containment.

The Director General of Health Services (DGHS) in the Ministry of Health, in a letter to the Principal Secretaries of health and medical education of states, said it has been observed that there is "inappropriate use" of N-95 masks, particularly those with valved respirators, by the public other than designated health workers.

The DGHS referred to the advisory on the use of homemade protective cover for face and mouth available on the website of the Ministry of Health.

"It is to bring to your knowledge that the use of valved respirator N-95 masks is detrimental to the measures adopted for preventing the spread of coronavirus as it does not prevent the virus from escaping out of the mask. In view of the above, I request you to instruct all concerned to follow the use of face/mouth cover and prevent inappropriate use of N-95 masks," DGHS Rajiv Garg said in the letter.

The government had in April issued an advisory on the use of homemade protective cover for face and mouth, asking people to wear it, particularly when they step out of their residences.

The advisory stressed such face covers must be washed and cleaned each day, as instructed, and stated that any used cotton cloth can be used to make this face cover.

The colour of the fabric does not matter but one must ensure that the fabric is washed well in boiling water for five minutes and dried well before making the face cover. Adding salt to this water is recommended, it said.

It also listed the procedures of making such homemade masks, asking to ensure it fits the face well and there are no gaps on the sides.

It urges people to wash hands thoroughly before wearing the face cover, switching to another fresh one as the face cover becomes damp or humid, and never reusing it after single use without cleaning it.

"Never share the face cover with anyone. Every member in a family should have separate face cover," the advisory stated.

India's COVID-19 case tally crossed the 11-lakh mark on Monday, while the total number of recovered patients increased to over seven lakh, according to Union health ministry data.

The death toll due to the disease rose to 27,497 with 681 fatalities reported in one day.

The ministry data updated at 8 am on Monday showed that a record single-day jump of 40,425 COVID-19 cases had taken the total number of cases to 11,18,043.

Despite tremendous advances in treatment of congenital heart disease (CHD), a new global study shows that the chances for a child to survive a CHD diagnosis is significantly less in low-income countries.

The research revealed that nearly 12 million people are currently living with CHD globally, 18.7 per cent more than in 1990.

The findings, published in The Lancet, is drawn from the first comprehensive study of congenital heart disease across 195 countries, prepared using data from the Global Burden of Diseases, Injuries and Risk Factors Study 2017 (GBD).

"Previous congenital heart estimates came from few data sources, were geographically narrow and did not evaluate CHD throughout the life course," said the study authors from Children's National Hospital in the US.

This is the first time the GBD study data was used along with all available data sources and previous publications - making it the most comprehensive study on the congenital heart disease burden to date.

The study found a 34.5 per cent decline in deaths from congenital disease between 1990 to 2017. Nearly 70 per cent of deaths caused by CHD in 2017 (180,624) were in infants less than one year old.

Most CHD deaths occurred in countries within the low and low-middle socio-demographic index (SDI) quintiles.

Mortality rates get lower as a country's Socio-demographic Index (SDI) rises, the study said.

According to the researchers, birth prevalence of CHD was not related to a country's socio-demographic status, but overall prevalence was much lower in the poorest countries of the world.

This is because children in these countries do not have access to life saving surgical services, they added.

"In high income countries like the United States, we diagnose some heart conditions prenatally during the 20-week ultrasound," said Gerard Martin from Children's National Hospital who contributed to the study.

"For children born in middle- and low-income countries, these data draw stark attention to what we as cardiologists already knew from our own work in these countries -- the lack of diagnostic and treatment tools leads to lower survival rates for children born with CHD," said researcher Craig Sable.

"The UN has prioritised reduction of premature deaths from heart disease, but to meet the target of 'ending preventable deaths of newborns and children under 5 years of age,' health policy makers will need to develop specific accountability measures that address barriers and improve access to care and treatment," the authors wrote.
