Over 1.5 lakh infants are born with a birth defect in their heart every year in India

About 78,000 infants born with congenital heart disease in India die every year because of inadequate health care facilities in the country, experts said. ‘Every year 1.5 lakh infants are born in India with congenital heart disease,’ Dr Murtaza Chisti, chief cardiac surgeon of the Mahatma Gandhi Cardiac and Critical Care Centre told reporters after conducting a medical camp here today.
Due to lack of awareness, cases of congenital heart disease are on the rise in the country. ‘Work-related tension coupled with lifestyle changes of young people and people in age group of 30 to 40 years make them susceptible to heart attacks,’ he said. ‘A controlled diet with minimal fatty and non-vegetarian food, non-consumption of sweets, coupled with adequate rest could reduce the incidence of heart problems, he said, adding that diabetes, high blood pressure, mental tension, increase in cholesterol were contributory causes for heart attacks.
Dr ML Swarankar, chairman of the India Education Trust, said that India had the dubious distinction of having the largest number of deaths in Asia owing to heart attack. More and well-equipped cardiac centres were needed to bring down the number, he added.
What is congenital heart disease (CHD)? How common is the condition in India?
According to a study published in the India Academy of Paediatrics [1], congenital heart disease is a condition seen in every 3.9 births per 1000 births in India. As described by Dr Amar Singhal, ‘Congenital heart disease is a defect in the heart at the time of birth. It is the structural or functional malfunctioning of the heart that is caused during its formation. While in some cases these defects are caught right after birth, in some cases it may be reported later on in the child’s life.’

Revealed – how the brain controls hunger

Although hunger is essential for survival, abnormal hunger can lead to obesity and eating disorders that are now reaching near-epidemic proportions around the world. The solution lies somewhere deep inside your brain. To unlock the mystery behind hunger pangs, researchers are creating a wiring diagram of the complex brain circuits that regulate the intense urge to munch in office or rush for refrigerator in night. ‘Our goal is to understand how the brain controls hunger,’ explained Bradford Lowell, an investigator with Massachusetts-based Beth Israel Deaconess Medical Center’s (BIDMC) division of endocrinology, diabetes and metabolism.
Abnormal hunger can lead to obesity and eating disorders, but in order to understand what might be wrong – and how to treat it – you first need to know how it works, added Lowell, also professor of medicine at Harvard Medical School. The findings show that Agouti-peptide (AgRP) expressing neurons – a group of nerve cells in the brain’s hypothalamus – are activated by caloric deficiency. When AgRP was either naturally or artificially stimulated in animal models, it caused mice to eat voraciously after conducting a relentless search for food. The hunger-inducing neurons that activate these AgRP neurons are located in the paraventricular nucleus – a brain region long thought to cause satiety, or feelings of fullness.
‘This unexpected finding adds an important dimension to our understanding of what drives appetite,’ said Lowell. To deal with this particularly complex brain region, the Lowell team is taking a step-by-step approach to find out how the messages indicating whether the body is in a state of feeding or fasting enter this system, said the study that appeared in the journalNature. ‘We are getting closer and closer to completing our wiring diagram. The nearer we come to understand how it all works, the better our chances of being able to treat obesity and eating disorders – the consequences of abnormal hunger,’ explained Lowell.
With the rising rate of obesity the world over, we though it is time we tell you exactly what that excess bit of fat does to your body.
