Watch your waistline for diabetes risk
A British health report has warned that adults with a large waistline are five times more likely to develop type 2 diabetes.

In its report, the Public Health England (PHE), an executive agency of Britain's Department of Health, said they encourage people to monitor their waistline and assess risk of developing type 2 diabetes.

According to the report, men having a large waist circumference of over 102cm (40 inches)are five times more likely to develop type 2 diabetes. Women with a large waist circumference of over 88cm (34.6 inches) are three times more likely to develop type 2 diabetes, Xinhua reported.

Currently 90 percent of the adults with type 2 diabetes are overweight or obese, and the prevalence of both obesity and diabetes are on the increase, said PHE experts.

Being overweight or obese is the main avoidable risk factor for type 2 diabetes, they added.

According to Alison Tedstone, chief nutritionist at PHE, type 2 diabetes is a very serious public health issue which can have significant consequences, such as limb amputations or blindness.

The key to reducing your chances of type 2 diabetes is losing weight which can be achieved through a healthy diet and being more active, she added.

The report also revealed that deprivation is closely linked to the risk of both -- obesity and diabetes in Britain, with type 2 diabetes being 40 percent more common among people in the poorest communities compared to the rich ones.

'Ebola could be a threat to Britain'
The fatal Ebola virus, which has killed hundreds of people since February, could be a threat to Britain, Foreign Secretary Philip Hammond said.

The disease has killed more than 600 people in West Africa, Xinhua reported.

According to Hammond, no Britons have been affected so far and the government has been viewing the outbreak very seriously.

"In terms of the UK, the issue is about the possibility of somebody who has contracted the disease in Africa getting sick here."

"It is not about the disease spreading in the UK because we have frankly different standards of infection control procedure that would make that most unlikely," Hammond said.

Public Health England (PHE) has already issued an alert to British doctors to be aware of Ebola symptoms.

Fears of global outbreak were raised last week, after a man showing signs of Ebola left Liberia on a flight to Lagos, where he later died.

Breastfeeding lowers risk of cardiovascular, metabolic diseases in kids
A new study has found that young adults who were breastfed for three months or more as babies have a significantly lower risk of chronic inflammation associated with cardiovascular and metabolic diseases.

The research from the Brown School at Washington University in St. Louis, shows that

birth weight and breastfeeding both have implications for children's health decades later.

The researchers used data from the US National Longitudinal Study of Adolescent Health, including parent surveys, and blood samples providing measurements of CRP.

These findings held up in a series of sibling models, in which one sibling was breastfed and the other was not. Such models provide improved confidence in the results by implicitly controlling for genetic factors for elevated CRP.

"These findings underscore the importance of a preventive approach but not limited to prenatal health care and postnatal breastfeeding support," said Molly W Metzger, co-author of the study with Thomas W McDade, PhD, of Northwestern University.

The study was published in the journal Proceedings of the Royal Society B: Biological Sciences.

Teenagers active in evenings more prone to insomnia
Have you witnessed your teenage son getting more active in the evenings compared to rest of the day? He may be prone to develop insomnia in addition to depression and anxiety.

Teenagers who are more active in the evenings are more likely to have depression and insomnia, research finds.

Such people are also more likely to have obsessive-compulsive disorder, separation anxiety and social phobia.

"Our findings suggest that the 'eveningness' chronotype - being more active in the evenings - is an independent risk factor for insomnia and depression," said Pasquale Alvaro from University of Adelaide's school of psychology.

In many countries, nearly 11 percent of teenagers aged 13-16 years experience insomnia at some stage.

Having insomnia in addition to anxiety or depression can further intensify the problems being experienced with each individual disorder.

"It can lead to such problems as alcohol and drug misuse during adolescence," Alvaro added.

To reach this conclusion, Alvaro surveyed more than 300 Australian high school students aged 12

18 to better understand their sleep habits, mental health condition and the time of day they were most active.

He found that the presence of insomnia was independently linked with depression, generalised anxiety disorder and panic disorder among teenagers.

The results were published in the journal Sleep Medicine.

Early reading skills make kids sharper
If you wish to see your kids emerge as intelligent adults, start now to mind their reading skills. Researchers have found that early reading skills might positively affect later intellectual abilities.

"Early remediation of reading problems might aid in not only the growth of literacy, but also more general cognitive abilities that are of critical importance across the lifespan," said Stuart Ritchie, a research fellow in psychology at University of Edinburgh in Britain.

"Children who do not receive enough assistance in learning to read may also be missing out on the important, intelligence-boosting properties of literacy," Ritchie said.

For the study, researchers looked at 1,890 identical twins who were part of the "Twins Early Development Study", an ongoing longitudinal study in Britain.

They examined scores from tests of reading and intelligence taken when the twins were aged seven, nine, 10, 12, and 16.

The researchers found that earlier differences in reading between the twins were linked to later differences in intelligence.

Reading was associated not only with measures of verbal intelligence (such as vocabulary tests) but with measures of nonverbal intelligence as well (such as reasoning tests).

The differences in reading that were linked to differences in later intelligence were present by age seven, which may indicate that even early reading skills affect intellectual development.

The study appeared in the journal Child Development.

New probe will allow early cancer detection in seconds
Scientists have revealed that they are developing a revolutionary new laser device that would allow on-the-spot diagnosis of cancer in just seconds.

According to the researchers from Birmingham City University and the University of Central Lancashire, the probe will detect cancers early and distinguish between different forms of the disease, the Daily Express reported.

Ryan Stables said that this could change the way we approach cancer - diagnosis so it is faster, potentially saving thousands of lives and this method of identifying cancerous cells is similar to that of using a metal detector.

Stables added that the probe allows you to recognise the characteristics of cancer in real-time, which they hope could have life-changing implications.

The non-invasive system, which is still in its early stages of development, detects malignant cells by the way in which laser light disperses from them and the researchers hope a probe could be in widespread use in surgeries within five years. It is intended for use on the skin and internally and for testing blood samples taken by the GP.

'Background TV' may affect kids' health: Study
A recent study has revealed that television programmes running in the back ground have a negative impact on the children, during their play and learn phase.

University of Iowa researchers found that background television could divert a child's attention from play and learning and that non-educational programs could negatively affect children's cognitive development.

The team found a relationship between the content children were exposed to and their executive function, an important facet in learning and development.

Deborah Linebarger, UI associate professor, said that Children, whose parents created a home environment that was loving and nurturing and where rules and expectations were the same from one time to another, were better able to control their behavior, display more empathy, and did better academically.

In particular, Linebarger suggested the parents to be mindful what their children view on the tube, especially the content of a show.

Researchers said that among the impacts of background TV, it recruited kids' attention away from other activities, such as play and learning.

The study was published in the Journal of Developmental and Behavioral Pediatrics.

Bacteria linked to obesity and diabetes found
Biologists have discovered an extremely widespread virus that could be as old as humans and could play a major role in obesity and diabetes.

More than half the world's population is host to the newly described virus, named crAssphage, which infects one of the most common types of gut bacteria, Bacteroidetes, the findings showed.

This phylum of bacteria is thought to be connected with obesity, diabetes and other gut-related diseases.

"It is not unusual to go looking for a novel virus and find one. But it is very unusual to find one that so many people have in common. The fact that it has flown under the radar for so long is very strange," said Robert Edwards, a bioinformatics professor at the San Diego State University in the US.

In the DNA fecal samples from 12 different individuals, the researchers noticed a particular cluster of viral DNA, about 97,000 base pairs long, that the samples all had in common.

When Edwards and his colleagues checked this discovery against a comprehensive listing of known viruses, they came up empty.

This was a new virus that about half the sampled people had in their bodies that nobody knew about.

The fact that it is so widespread indicates that it probably is not a particularly young virus, either.

"We have basically found it in every population we have looked at," Edwards said.

"As far as we can tell, it is as old as humans are," he said.

The study appeared in the journal Nature Communications.

Girls' puberty age depends on which parent's 'imprinted gene' they carry
A new study has found that the puberty age of girls largely depends on which of the two parents' 'imprinted' genes they have.

The findings come from an international study of more than 180,000 women involving scientists from 166 institutions worldwide, including the University of Cambridge. The researchers identified 123 genetic variations that were associated with the timing of when girls experienced their first menstrual cycle by analysing the DNA of 182,416 women of European descent from 57 studies. Six of these variants were found to be clustered within imprinted regions of the genome.

Lead author Dr John Perry from the University of Cambridge said that normally, the inherited physical characteristics reflect a roughly average combination of our parents' genomes, but imprinted genes place unequal weight on the influence of either the mother's or the father's genes, it was found that one parent may more profoundly affect puberty timing in their daughters than the other parent.

He added that they knew some imprinted genes controlled antenatal growth and development, but there was an increasing interest in the possibility that imprinted genes may also control childhood maturation and later life outcomes, including disease risks.

Senior author Dr Ken Ong said that they were also studying the genetic factors to understand how early puberty in girls is linked to higher risks of developing diabetes, heart disease and breast cancer in later life, and to hopefully one day break this link.

The research is published in the journal Nature.

Brain next frontier to treat obesity
Therapies aimed at areas of the brain responsible for memory and learning could lead to better treatment of obesity and dementia, says a study.

"This is a novel way for health care providers who treat people with weight problems and for researchers who study dementia to think about obesity and cognitive decline," said professor Terry Davidson from the American University in the US.

Researchers reviewed findings linking obesity with cognitive decline, including the "vicious cycle" model, which explains how weight-challenged individuals who suffer from particular kinds of cognitive impairment are more susceptible to overeating.

It is widely accepted that over consumption of dietary fats, sugar and sweeteners can cause obesity. These types of dietary factors are also linked to cognitive dysfunction.

Experiments in rats by the researchers showed that over consumption of foods high in saturated fats and simple carbohydrates can damage or change the blood-brain barrier, the tight network of blood vessels protecting the brain and substrates for cognition.

Certain kinds of dementia are known to arise from the breakdown in these brain substrates.

"Treating obesity successfully may also reduce the incidence of dementia, because the deterioration in the brain is often produced by the same diets that promote obesity," concluded the study that appeared in the journal Physiology & Behavior.
