One in 10 'are secret smokers'

One in 10 'are secret smokers'

One in 10 people are "secret smokers" who try to keep their habit hidden, a survey suggests.

The poll of 4,000 adults, commissioned by Boots, found 52% of smokers had kept their habit secret from their parents, even into adulthood.

Three out of 10 of smokers had lied to their GP, and a quarter had kept it concealed from their employer.
A third admitted lying to their family, who believed they had given up or had never smoked at all.
Long-term damage
Angela Chalmers, a pharmacist at Boots, said: "Not many people realise that those one or two crafty cigarettes a day can still cause long-term damage to your health.

"Higher levels of carbon monoxide in your bloodstream means less oxygen is getting round your body.

"It can also affect the elasticity of the lungs, meaning you are putting yourself at risk of asthma and ageing your lungs well beyond your years."
The research found that smokers in London were most likely to keep their habit secret, closely followed by those in Yorkshire.
Seven out of 10 "secret smokers" admitted that they would like to give up for good this year
From July this year smoking will be banned in public places across the whole of the UK.
Amanda Sandford, of the charity Action on Smoking and Health, said: "It is understandable that smokers - particularly those who have tried to give up before and failed - might feel guilty about their smoking.

"But denying their habit won't help and they may find it harder to give up."
'Up to you'

Neil Rafferty, of the smokers' lobby group Forest, said he had known of many smokers who had hidden their habit.
"I always felt sorry for them. It's another example of how those in authority are determined to make us all feel like naughty children.
"But the truth is everyone is well aware of the risks, so if you want to smoke it's up to you.
"Smokers, secret or not, should not allow themselves to be browbeaten and chastised like this.
"As long as you're not deliberately bothering anyone else you have nothing to feel guilty about.
"It's your body and your life and you should tell the health freaks to butt out."

Fish contaminated with mercury 'pose worldwide threat to health'

A worldwide warning about the risks of eating mercury-contaminated fish is to be issued by an international group of scientists today.

Three times more mercury is falling from the sky than before the Industrial Revolution 200 years ago, the scientists say.

Fish absorb the toxic chemical, which pollutes the seas, posing a risk especially to children and women of childbearing age. The role of low-level pollutants such as lead and mercury on the growing brain has been known for decades and measures have been taken to reduce exposure to a minimum. But the scientists say more must be done.

The warning is based on five papers by mercury specialists summarising the current state of knowledge on the chemical published in the international science journal Ambio. Called the Madison Declaration on Mercury Pollution, it presents 33 key findings from four expert panels over the past year. Every member of the four panels backed the declaration which was endorsed by more than 1,000 scientists at an international conference on mercury pollution in Madison, Wisconsin, in the US last August.

However, it runs counter to research by British scientists last month which found pregnant women who ate the most fish had children who were more advanced, with higher IQs and better physical abilities.

The British researchers said that while mercury is known to harm brain development, fish also contain omega-3 fatty acids and other nutrients which are essential to brain development. They studied 9,000 families taking part in the Children of the 90s project at the University of Bristol and concluded, in The Lancet, that the risks of eating fish were outweighed by the benefits.

The US scientists focused on the risks of mercury which they say now constitute a "public health problem in most regions of the world". In addition to its toxic effects on the human foetus, new evidence indicates it may increase the risk of heart disease, particularly in adult men.

While developed countries have reduced mercury emissions over the past 30 years, these have been offset by increased emissions from developing nations.

The uncontrolled use of the metal in small-scale gold mining is contaminating thousands of sites around the world, putting 50 million inhabitants of mining regions at risk and contributing 10 per cent of the global burden of the pollutant attributable to human activities in the atmosphere.

The global spread of the threat is revealed in increased mercury concentrations now being detected in fish-eating species in remote areas of the planet. The impact on marine eco-systems may lead to population declines in these species and in fish stocks.

Professor James Wiener, of the University of Wisconsin, said: "The policy implications of these findings are clear. Effective national and international policies are needed to combat this global problem."

In the US, official government advice is for pregnant women to limit their consumption of all seafood, including white fish, oily fish and shellfish, to no more than 12oz (340g) a week in order to limit their exposure to mercury.

In the UK, the Food Standards Agency advises expectant mothers to avoid shark, swordfish and marlin and to limit their consumption of tuna, because these are the fish with the highest levels of mercury.

The key findings

* Three times more mercury is falling from the sky today than before the Industrial Revolution

* Eating fish is the primary way most people are exposed to the toxic metal

* There is solid scientific evidence of the toxic effects of mercury on the developing foetus

* Mercury exposure now constitutes a public health problem in most regions of the world

* New evidence suggests exposure to mercury may increase the risk of heart disease and stroke in men

* Increased mercury emissions from developing countries over the past 30 years have outstripped declines in the developed world

* Increasing mercury concentrations are now being detected in fish-eating wildlife in remote areas of the planet

Surgeon General: Teen Drinking a Problem

Americans need a wake-up call about the widespread use of alcohol by millions of underage drinkers, acting Surgeon General Kenneth Moritsugu said Tuesday.

Moritsugu issued a report that he said was designed to get all sectors of society involved in solving a major health problem. He described alcohol as the drug of choice for teens.

The 2005 National Survey on Drug Use and Health estimates there are 11 million underage drinkers in the United States. Nearly 7.2 million are considered binge drinkers, typically meaning they drank more than five drinks on occasion.

"Alcohol remains the most heavily abused substance by America's youth," Moritsugu said. He said the report calls for a "change in the culture and attitudes toward drinking in America. We can no longer ignore what alcohol is doing to our children."

Moritsugu urged more research on adolescent alcohol use and its relationship to physical and mental development. He said there is new research that indicates alcohol may harm the development of the brain in adolescents.

Although there has been a significant decline in tobacco and illicit drug use among teens, underage drinking has remained at consistently high levels, he said. In part, that high use stems from tolerance by adults

"Too many Americans consider underage drinking a rite of passage to adulthood," said Moritsugu. "Research shows that young people who start drinking before the age of 15 are five times more likely to have alcohol-related problems later in life."

More Gene Mutations Drive Cancer Than Previously Thought

More Gene Mutations Drive Cancer Than Previously Thought

Scientists surveying the human genome have found that many more gene mutations drive the development of cancer than previously thought.

The survey is reported in the journal Nature.

In the largest survey of its kind, an international team comprising over 60 scientists from the UK, Hong Kong, the Netherlands, Belgium, USA and Australia, working for the Cancer Genome Project, examined more than 500 genes and 200 cancers and sequenced more than 250 million letters of DNA code.

They found about 120 new genes that drive the development of cancer cells.

All cancers are thought to be caused by gene mutations. Genes control the behaviour of cells, for example they tell them when to divide and when to die; thus abnormal genes either issue faulty instructions or the correct instructions at the wrong time or both, which leads to abnormal cell development and cancer.

Michael Stratton from the Wellcome Trust's Sanger Institute in Cambridge, UK, and one of the survey team leaders said "This is a lot more cancer genes than we expected to find."

The survey also discovered that two types of gene mutation are involved in cancer: driver and passenger. The driver mutations are thought to drive the rampant cell growth that causes cancer, while the passenger ones, which exist in much larger numbers, just go along for the ride.

Of the 1,000 cancer-specific mutations found, the team believes that about 150 of them are driver genes.

It is not easy to spot the difference between a driver and passenger gene, something this survey suggests will pose a great challenge for scientists.

Dr Andy Futreal, co-leader of the Cancer Genome Project explained "It turns out that most mutations in cancers are passengers."

"However, buried amongst them are much larger numbers of driver mutations than was previously anticipated. This suggests that many more genes contribute to cancer development than was thought," he added.

The types of genes that Futreal and his colleagues investigated are known as kinase genes. They have been linked with cancer development before. These protein genes act like relays, switching different types of cell behaviour on and off.

One example of a kinase gene is the BRAF, which an earlier study showed to be mutated in 60 per cent of malignant melanomas. This led to the development of new drugs, now in clinical trials, to treat melanoma.

This broader survey covered a wider range of the more common types of cancer, including breast, lung, colorectal and stomach cancers.

The researchers also found that a particular group of kinase genes "involved in the Fibroblast Growth Factor Receptor signalling pathway was hit much more than we expected, particularly in colorectal cancers," said Dr Futreal.

The survey also showed that buried inside each mutation are important coded messages, and that the type of mutation varied widely between different cancer types. This suggests that in some cases the process of mutation begins decades before the cancer presents itself.

It is as though gene mutations are "archeological sites" where written inside the DNA of each cell is a historical coded pattern that reveals the original cause of the cancer. In some cases the code can be deciphered, for instance damage from UV radiation or sunlight, or carcinogens in tobacco smoke, but in other cases the code is too hard to crack, which means more research effort is needed to unravel their mysteries.

"This study vindicates all of the effort that went into the Human Genome Project," said Dr Mark Walport, Director of the Wellcome Trust, the largest independent charity in the UK and the second largest medical research charity in the world, and the sponsors of the survey.

"Understanding the mutations that cause cancer is crucial in order to develop accurately targeted treatments," added Dr Walport
