Should NICE and other UK medical authorities be recommending to doctors that most people in UK between 55-65 years should take a daily 75mg aspirin, as a cancer and heart disease preventative? 

David Agus is suggesting that public policy in USA should be to encourage aspirin’s use in those for whom the potential benefits would be obvious and the risks minimal.

Elsewhere, I've reviewed the case for preventative use of aspirin (90+ links), focussing on research by Peter Rothwell (50+ links) at Oxford.

The 2,000-Year-Old Wonder Drug Published: December 11 2012 with 107 Comments

David B. Agus (wikipedia) is a professor of medicine and engineering at the University of Southern California and the author of “The End of Illness.”


"THE inexorable rise in health care spending, as all of us know, is a problem. But what’s truly infuriating, as we watch America’s medical bill soar, is that our conversation has focused almost exclusively on how to pay for that care, not on reducing our need for it. In the endless debate about “health care reform,” few have zeroed in on the practical actions we should be taking now to make Americans healthier.

An exception is Mayor Michael R. Bloomberg of New York, who is setting new standards that we would do well to adopt as a nation. In the last several years, he’s changed the city’s health code to mandate restrictions on sodas and trans fats — products that, when consumed over the long term, harm people. These new rules will undoubtedly improve New Yorkers’ health in years to come.

Such bold moves prompt a provocative question: when does regulating a person’s habits in the name of good health become our moral and social duty? The answer, I suggest, is a two-parter: first, when the scientific data clearly and overwhelmingly demonstrate that one behaviour or another can substantially reduce — or, conversely, raise — a person’s risk of disease; and second, when all of us are stuck paying for one another’s medical bills (which is what we do now, by way of Medicare, Medicaid and other taxpayer-financed health care programs).

In such cases, encouraging a healthy behaviour  or discouraging an unhealthy one, ought to be a matter of public policy — which is why, for instance, we insist on vaccinating children for the measles, mumps, rubella and polio; we know these preventive strategies save lives.

Under that rationale, then, why not make it public policy to encourage middle-aged people to use aspirin?

Developed in 1897 by the German chemist Felix Hoffmann, aspirin, or acetylsalicylic acid, has long proved its value as an analgesic. Two millenniums before that, Hippocrates, the father of modern medicine, used its active ingredient — which he extracted from the bark and leaves of the willow tree — to help alleviate pain and fevers.

Since then, we've gained insight into both the biological mechanism and the effects of this chemical compound. Many high-quality research studies have confirmed that the use of aspirin substantially reduces the risk of cardiovascular disease. Indeed, the evidence for this is so abundant and clear that, in 2009, the United States Preventive Services Task Force strongly recommended that men ages 45 to 79, and women ages 55 to 79, take a low-dose aspirin pill daily, with the exception for those who are already at higher risk for gastrointestinal bleeding or who have certain other health issues. (As an anticoagulant, aspirin can increase the risk of bleeding — a serious and potentially deadly issue for some people.)

New reports about aspirin’s benefits in cancer prevention are just as convincing. In 2011, British researchers [Peter Rothwell - over 50 links on crabsallover blog], analysing data from some 25,000 patients in eight long-term studies, found that a small, 75-milligram dose of aspirin taken daily for at least five years reduced the risk of dying from common cancers by 21 percent.

In March, The Lancet published two more papers bolstering the case for this ancient drug. The first, reviewing five long-term studies involving more than 17,000 patients, found that a daily low-dose aspirin lowered the risk of getting adenocarcinomas — common malignant cancers that develop in the lungs, colon and prostate — by an average of 46 percent.

In the second, researchers at Oxford and other centres compared patients who took aspirin with those who didn’t in 51 different studies. Investigators found that the risk of dying from cancer was 37 percent lower among those taking aspirin for at least five years. In a subsection of the study group, three years of daily aspirin use reduced the risk of developing cancer by almost 25 percent when compared with the aspirin-free control group.

The data are screaming out to us. Aspirin, one of the oldest remedies on the planet, helps prevent heart disease through what is likely to be a variety of mechanisms, including keeping blood clots from forming. And experts believe it helps prevent cancer, in part, by dampening an immune response called inflammation.


So the question remains: given the evidence we have, why is it merely voluntary for physicians to inform their patients about a health care intervention that could not only help them, but also save untold billions in taxpayer dollars each year?

For some men over the age of 45 and women over 55, the risks of taking aspirin outweigh any benefits — and patients should talk with their doctors before taking any medication, including something as familiar as aspirin.

But with such caveats in place, it still ought to be possible to encourage aspirin’s use in those for whom the potential benefits would be obvious and the risks minimal. Just as we discourage smoking through advertising campaigns, for example, shouldn't we suggest that middle-aged Americans speak to their doctors about aspirin? Perhaps pharmacists or even health insurance companies should be enlisted to help spread the word about this disease-prevention drug?

The right policy will have to be hammered out, of course. But if we’re going to address the country’s sky-high medical bill, we’re going to have to address the need for Americans to be active in protecting their own health.

Everyone may want the right to use tobacco products and engage in other behaviours that are unequivocally linked with disease — or have the right not to wear a seat belt and refrain from other actions that may protect their well-being. But, if so, should society have the obligation to cover the costs of the consequences?

As the former Supreme Court justice Potter Stewart once said, “There is a big difference between what we have the right to do and what is right to do.” Health care reform should, at long last, focus on the latter."

NICE recommendations on how to reduce CVD (Cardiovascular disease)

reposted from: NHS Choices


Protect the population from the harmful effects of trans fats
  • Eliminate the use of industrially produced trans fatty acids (IPTFAs) for human consumption.
  • In line with other EU countries (specifically Denmark and Austria), introduce legislation to ensure that IPTFA levels do not exceed 2% in the fats and oils used in food manufacturing and cooking.
  • Establish guidelines for local authorities to independently monitor IPTFA levels in the restaurant, fast-food and home food trades using existing statutory powers (in relation to trading standards or environmental health)

Does this guidance apply to me?

This guidance is aimed at improving the health of the population as a whole. It makes recommendations to people who can make changes to improve population health.
However, the principles underlying the recommendations also apply to individuals. For example, most people should reduce their salt, saturated fat and trans fat intake, as well as increasing their levels of physical activity.
Related NICE guidance focuses more on individuals, including guidance on stopping and preventing smoking and tobacco control, physical activity, obesity, high blood pressure and mother and child nutrition.

Take away restaurants promise to lower salt

21/11/2008

Key points

  • Fast food restaurants have committed to lowering their levels of salt and fat
  • Eating too much salt raises your blood pressure. People should eat no more than 6 grams of salt a day to avoid high blood pressure
  • High blood pressure causes strokes and heart attacks
  • Eating too much saturated and trans fats clogs up your arteries with cholesterol and raises your risk of strokes and heart attacks
  • Lowering salt and fat in fast food meals will help in the fight against strokes and heart disease caused by high blood pressure and high cholesterol

Six of Britain’s biggest fast-food restaurants have committed to making their burgers and sandwiches more healthy.

Burger King, KFC, McDonald’s, Nando’s, Subway and Wimpy have promised to lower the salt and saturated or trans fats in their meals to make them more heart and blood pressure friendly.

Trans-fats banned in California

Trans-fats are used in many fried and baked foods

California has become the first US state to ban restaurants and food retailers from using trans-fats, which are linked to coronary heart disease.

Governor Arnold Schwarzenegger said the new legislation, which will take effect in 2010, represented a "strong step toward creating a healthier future".

Violations will incur fines of between $25 (£13) and $1,000 (£502).

Trans-fats are chemically altered vegetable oils, used to give processed foods a longer shelf-life.

Some cities, like New York City, Philadelphia and Seattle, have already banned the fats. Many food makers and restaurant chains have also been experimenting with replacements for oils and foods that contain them.

'Tremendous benefit'

Trans-fats are produced artificially in a process called hydrogenation which turns liquid oil into solid fat.

They can be used for frying or baking, or put into processed foods and ready-made mixes for cakes and drinks like hot chocolate.

Trans-fats are used because they are cheap, add bulk to products, have a neutral flavour and give products a long shelf-life. They have no nutritional value.

Used to extend shelf life of products
Put into pastries, cakes, margarine and some fast foods
Can raise levels of "bad" cholesterol
Even a small reduction in consumption can cut heart disease
They have no nutritional benefit
The US Food and Drug Administration estimates that on average, Americans eat 4.7lb (2.14kg) of trans-fats each year.

A review by the New England Journal of Medicine in 2006 concluded that there was a strong connection between the consumption of trans-fats and coronary heart disease. It found they boosted "bad" cholesterol levels in the body.

The review said that eliminating artificial trans-fats from the food supply could prevent between six and 19% of heart attacks and related deaths each year.

The legislation signed by Mr Schwarzenegger will ban from 1 January 2010 the use of trans-fats in oil, shortening and margarine used in spreads or for frying.

The president of the California Academy of Family Physicians, Jeffrey Luther, said that the law,

"when it finally takes effect, will be a tremendous benefit", adding that there was no safe level of consumption, as with cigarettes.

The California Restaurant Association opposed the ban, but a spokesman said that it had no plans to challenge it in the courts, in part because some restaurants have already begun to phase out trans-fats to satisfy customers.
