World Anti-Obesity Day: Is your child's obesity giving you nightmare?

November 26, 2016

New Delhi, Nov 26: After the United States of America, the epidemic of childhood obesity is gripping India. According to an international journal, by 2025, India will have over 17 million obese children and stand as second highest country in the world with obese children as per Pediatric Obesity.

obsThe rising prevalence of obesity in children is also bringing with it countless other adverse health effects, which make this condition a serious public health concern.

According to Satish Kannan, Co-founder and CEO of DocsApp, Obese children are at a greater risk of acquiring diabetes, high blood pressure, high cholesterol, cardiovascular diseases, bone and joint problems, sleep apnea, and social and psychological problems such as stigmatization and poor self-image.

Parents can be attributed to some degree for this problem as they often neglect the unhealthy dietary habits and patterns followed by these children. Popular culture that introduces them to junk food, snacks, colas etc and markets these items in the most attractive of ways adds to the issue.

Childhood obesity is a complex health issue which is not just influenced by unhealthy dietary habits, but also by the lifestyle and behavioral choices made by parents and children alike.

Children nowadays prefer to stay indoors than playing outside and are more exposed to screens like TV, tablets and mobile screens like never before. Meanwhile, there are parents who pressurise their kids to focus more on academics with little or no motivation to indulge in any outdoor games or sports. This lack of physical activity, which is a key determinant of energy expenditure and a fundamental part of energy balance and weight control, triggers obesity and chronic health conditions in them, said Kannan.

Genetic conditions are yet another factor that only increases the chances of obesity in children, which means children with overweight parents can also inherit the problem.

However, genetics alone cannot cause obesity. They merely increase one's propensity to put on weight easily. Ultimately, it's only the children who eat more calories than they need for their growth and energy who become obese.

No matter how much parents are to be blamed, the good news is that only they have the potential to influence their child's lifestyle and weight. For them, it can be difficult sometimes to figure out whether their child is overweight because a child may not look particularly heavy to be overweight.

Moreover, with a growing number of children becoming heavier at a younger age, they become used to seeing bigger children.

In such situations, determine the body fat directly is difficult and the diagnosis can be done through BMI rate. Children with a BMI equal to or exceeding the age-gender can be called obese.

Parents can do a lot to help their child maintain a healthy weight. To begin with, they can simply take charge as their role models by inculcating good habits in their children and encouraging them to be active and eat well by doing so themselves.

Parents must start a ritual of going for walks or cycling every day with their kids instead of watching TV or surfing the internet. This will not only make them realize that being active can be fun, it will be a great way for the entire family to spend time together.

Children crave for attention and care and those who are deprived of it, have a higher risk of obesity. So instead of using food as a comfort measure, parents must help them develop healthy eating habits by initiating ways to make their favorite dishes healthier, and reduce calorie-rich temptations by letting them enjoy those goodies as well once in a while as a treat.

Parents should also avoid serving their children oversized portions and start with small servings. They must also be encouraged to eat slowly in their set mealtimes. The mealtimes can be further utilised as an opportunity to catch up on their day to day activities.

Both the parents and children must make it a custom to eat healthy and aim for five or more portions of fruit and vegetables every day in the form of juices, smoothies, beans, and pulses, to ramp up their fiber, vitamins and minerals intake.

The idea is to get a maximum number of calories from healthier and nutrient-rich foods like fruit and vegetables, bread, potatoes, fish, chicken, rice and whole grains instead of sugary or high-fat foods like sweets, cakes, biscuits, sugary cereals, and sugar-sweetened fizzy drinks.

Children are the future pillars of a nation and their health and fitness are crucial for the overall growth and development of the country.

So, it becomes not just the responsibility of the parents, but the entire community around them including schools, child care settings and medical care providers, government agencies to be equally concerned about childhood obesity and take meaningful steps to nip the problem in the bud.

Los Angeles, Feb 23: According to researchers, if administered quickly, a common medication that reduces bleeding could be a treatment for bleeding stroke.

The Spot Sign and Tranexamic Acid on Preventing ICH Growth - Australasia Trial (STOP-AUST) was a multicenter, prospective, randomized, double-blind, placebo-controlled, phase 2 clinical trial using the antifibrinolytic agent tranexamic acid in people with intracerebral hemorrhage (ICH).

ICH is a severe form of acute stroke with few treatment options.

Tranexamic acid is currently used to treat or prevent excessive blood loss from trauma, surgery, tooth removal, nosebleeds and heavy menstruation. For this study, one hundred patients with active brain bleeding were given either intravenous tranexamic acid or placebo within 4.5 hours of symptom onset.

Researchers analyzed brain CT scans taken during the 24-hour period after treatment with tranexamic acid or placebo.

Researchers found a trend towards reduced hemorrhage expansion in the group treated with tranexamic acid, especially in those treated within 3 hours of the brain bleed. However, this trend was not statistically significant. The finding was consistent with previous research using the medication.

"Further trials using tranexamic acid are ongoing and focusing on ultra-early treatment - within 2 hours. 

This is where the greatest opportunity for intervention appears to be. Tranexamic acid is inexpensive, safe and widely available. Our results and others provide great impetus for further, focused research using this treatment," Nawaf Yassi said.

Larger trials focused on patient outcomes are required for this therapy to enter routine clinical practice.

Taking multiple courses of antibiotics within a short span of time may do people more harm than good, suggests new research which discovered an association between the number of prescriptions for antibiotics and a higher risk of hospital admissions.

Patients who have had 9 or more antibiotic prescriptions for common infections in the previous three years are 2.26 times more likely to go to hospital with another infection in three or more months, said the researchers.

Patients who had two antibiotic prescriptions were 1.23 times more likely, patients who had three to four prescriptions 1.33 times more likely and patients who had five to eight 1.77 times more likely to go to hospital with another infection.

"We don't know why this is, but overuse of antibiotics might kill the good bacteria in the gut (microbiota) and make us more susceptible to infections, for example," said Professor Tjeerd van Staa from the University of Manchester in Britain.

The study, published in the journal BMC Medicine, is based on the data of two million patients in England and Wales.

The patient records, from 2000 to 2016, covered common infections such as upper respiratory tract, urinary tract, ear and chest infections and excluded long term conditions such as cystic fibrosis and chronic lung disease.

The risks of going to hospital with another infection were related to the number of the antibiotic prescriptions in the previous three years.

A course is defined by the team as being given over a period of one or two weeks.

"GPs (general physicians) care about their patients, and over recent years have worked hard to reduce the prescribing of antibiotics,""Staa said.

"But it is clear GPs do not have the tools to prescribe antibiotics effectively for common infections, especially when patients already have previously used antibiotics.

"They may prescribe numerous courses of antibiotics over several years, which according to our study increases the risk of a more serious infection. That in turn, we show, is linked to hospital admissions," Staa added.

It not clear why hospital admissions are linked to higher prescriptions and research is needed to show what or if any biological factors exist, said the research team.

"Our hope is that, however, a tool we are working for GPs, based on patient history, will be able to calculate the risks associated with taking multiple courses of antibiotics," said Francine Jury from the University of Manchester.

Washington, Feb 21: The fat around arteries may play an important role in keeping the blood vessels healthy, according to a study in rats that may affect how researchers test for treatments related to plaque buildup, as seen in conditions leading to heart attack.

The study, published in the journal Scientific Reports, noted that the fat, known as perivascular adipose tissue, or PVAT, helps arteries let go of muscular tension while under constant strain.

According to the researchers, including Stephanie W. Watts from the Michigan State University in the US, this feature is similar to how the bladder expands to accommodate more liquid, while at the same time keeping it from spilling out.

"In our study, PVAT reduced the tension that blood vessels experience when stretched," Watts said.

"And that's a good thing, because the vessel then expends less energy. It's not under as much stress," she added.

According to Watts and her team, PVAT has largely been ignored by researchers believing its main job was to store lipids and do little more.

Until now, she said, scientists only divided blood vessels into three parts, the innermost layer called the tunica intima, the middle layer called the tunica media, and the outermost layer called the tunica adventitia.

Watts believes PVAT is the fourth layer, which others have called tunica adiposa.

Tunica, she said, meant a membranous sheath enveloping or lining an organ, and adiposa is a synonym for fat.

"For years, we ignored this layer -- in the lab it was thrown out. In the clinic it wasn't imaged. But now we're discovering it may be integral to our blood vessels," Watts said.

"Our finding redefines what the functional blood vessels are, and is part of what can be dysfunctional in diseases that afflict us, including hypertension. We need to pay attention to this layer of a blood vessel because it does far more than we originally thought," she added.

Earlier studies, Watts said, had shown that PVAT plays a role in the functioning of blood vessels, finding that it secretes substances that can cause blood vessels to relax as well as substances that can cause it to contract.

In the current study, the researchers decided to test whether PVAT provides a structural benefit to arteries by assisting the function of stress relaxation.

They tested the thoracic aorta in rats, and found those with intact PVAT had more stress relaxation than those without.

The study revealed that the pieces of artery with surrounding fat had measurably relaxed more than those without.

Watts and her colleagues then tested other arteries, and were able to duplicate the same response.

"It's not something you see only in this particular vessel or this particular species or this particular strain. But that maybe it's a general phenomenon," she said.
