Births at home as safe as hospital, study suggests

There is a lot of ideology surrounding home births so these results should be treated with caution. Successful homebirth programs are the ones with rapid access to hospitals if things start to go wrong -- and in some places that may mean access to a private hospital as triage for pregnancy problems at government hospitals can sometimes be shockingly lax. Hospitals kill babies too

Midwives are calling for a "seismic shift" to enable more women to give birth at home after a study suggesting that home deliveries can be as safe as those in hospital. Research covering nearly 530,000 births in the Netherlands found that women had a no greater risk of their baby dying or becoming ill if they gave birth at home rather than in hospital. The Royal College of Midwives said that the study was a "major step forward" in showing that home births were safe for women with low risk of complications, but added that the NHS would need a fundamental reorganisation to support more home births.

The Government has promised all women in England a choice of where they would prefer to give birth by the end of this year, but experts say that a lack of community midwives could make this unrealistic in many areas. According to the RCM Royal College of Midwives an extra 5,000 full-time midwives are needed urgently to fulfil this and other pledges on maternity, but ministers have promised only to recruit an extra 3,400 full-time midwives by 2012.

Louise Silverton, the deputy general secretary of the college, said that "to begin providing more home births there has to be a seismic shift in the way maternity services are organised. "The NHS is simply not set up to meet the potential demand for home births, because we are still in a culture where the vast majority of births are in hospital. There also has to be a major increase in the number of midwives because they are the people who will be in the homes delivering the babies."

Celebrity mothers including Davina McCall and Charlotte Church are credited with making home births more popular, but less than 3 per cent of all births in England and Wales took place at home in 2006, the latest figures show. This compares with nearly one in three (30 per cent) of all births taking place at home in Holland.

Lying down during the early stages of childbirth may prolong the agony of labour, a review of medical evidence by the Cochrane Collaboration suggests. Researchers found that the first stage of labour was significantly shorter for women who kneel, stand up, walk around or sit upright. The review by the Cochrane Collaboration, the organisation that promotes evidence-based medicine, used data from 21 studies involving 3,706 women in developed countries since the 1960s. The first stage of labour was about an hour shorter in those who adopted upright positions compared to those who lay down, the researchers said.

Annemarie Lawrence, of the Institute of Women's and Children's Health at the Townsville Hospital in Queensland, Australia, commented: "In most developing countries, women stand up or walk around as they wish during the early stages of birth with no ill effects. Based on these results, we would recommend that women are encouraged to use whichever positions they find most comfortable, but are specifically advised to avoid lying flat."

Childhood photos could hold the secret to your marriage

Happiness is largely a disposition and it is no surprise that happy people are less likely to get dissatisfied with their marriages

If you ever wondered whether your marriage might end in divorce, the answer might lie in a family album. According to scientists it is possible to predict whose marriages will fail by looking at photographs taken decades earlier. Those with the brightest smiles are more than three times as likely to have a strong marriage than those who frown their way through family outings as a child or teenager. Even snaps taken at the age of five yield clues about the path a person's life will take.

'Smile intensity predicted whether or not participants divorced at some point in their lives,' said the researchers. 'The less intensely participants smiled, the more likely they would be divorced later in life.' To make the link, the researchers asked almost 650 adults for pictures taken during their final year of school and rated the brightness of their smiles. The men and women ranged in age between 21 and 87, meaning some of the snaps were 70 years old.

The scientists, from DePauw University in Indiana, then asked the volunteers if they had ever been divorced - and matched their answers with the data on their smiles. Those with the weakest smiles were more than three times as likely to have been through a divorce than those who beamed their way through their teenage years, the journal Motivation and Emotion reports.

A second experiment, which included pictures taken when people were as young as five confirmed the finding. The researchers think it is possible that happy sorts are more likely to try to work through rocky spots in relationships. Alternatively, those with a sunny disposition may marry similarly upbeat souls. It is also possible that happiness is contagious.

Health freaks do harm again

Eight years ago, engineers and officials in Washington, D.C. decided to give the go-ahead for a program that would eliminate the "potentially carcinogenic by-products" of chlorine in tap water. The program replaced chlorination with chloramination, and it worked. However, in the next three years, hundreds of families with homes fitted with lead pipes in the District of Columbia were exposed to dangerously high lead levels. Unknown to scientists at the time, the chlorine in tap water served as a 'binder' for the lead pipes, keeping a certain amount of lead from dissolving in the water. In 2004, the chlorination method was restored. Still, in the first half of that year, 74 out of 108 household taps sampled had lead concentrations above the "EPA action level," some astronomically so.

Numerous studies confirm that very low levels of lead in blood are linked to short attention spans and reading problems in children. In adults, low levels are linked to high blood pressure and an increased risk of death from heart disease and stroke. If not detected early, children with high levels of lead in their bodies can suffer from brain and nervous system damage, stunted growth, and hearing problems.

An investigation by Rebecca Renner of Salon has revealed that the Center for Disease Control(CDC) had withheld evidence of dangerously high levels. An influential CDC report released in 2004 (and since cited by officials in Seattle to calm nervous parents) downplayed the role that chloramination played in the D.C. lead crisis, saying that it "might have contributed a small increase in blood lead levels." However, according to Renner, "the results of thousands of blood tests that measured lead contamination in children were missing from the report, potentially skewing the findings and undermining public health. Further, the CDC discovered in 2007 that many young children living in D.C. homes with lead pipes were poisoned by drinking water and suffered ill effects. Parents wondered whether the water could have caused speech and balance problems, difficulty with learning, and hyperactivity. Yet the health agency did not publicize the new findings or alert public health authorities in D.C. or other federal agencies that regulate lead, such as the U.S. Environmental Protection Agency or Housing and Urban Development."

The principle author of the 2004 CDC lead report, Mary Jean Brown, stands by her conclusion that exposure to lead was minor, on the grounds that only tests that revealed low lead levels were lost.

A government scientist spoke to Renner about Brown's justification for excusing the 'lost data.' "When CDC learned the data was missing, someone could have called the lab and asked for it. If it was the lab's mistake, they would have sent the data." Environmental engineer Marc Edwards of Virginia Tech is conducting his own investigation, and found that numerous high results were also omitted.

Edwards was disturbed by what he found in his re-examination of drinking-water and lead blood-level data. In 2007, Edwards filed a complaint of scientific misconduct with the CDC, alleging that Brown knew about serious flaws in the data but refused to acknowledge them when writing the 2004 CDC report.

CDC is not the only authority implicated in the cover-up of D.C.'s lead problem. Also under fire for their handling of the crisis is the city's Water and Sewer Authority and Health Department (WASA). WASA sent inspectors to the homes of children with elevated blood lead to look for the source. A congressional hearing forced officials to testify that in every case the assessments showed that water was not the source of the child's lead exposure. But a recent re-assessment, conducted by Edwards, revealed that water was the sole source of the blood poisoning in some homes.

Even though hundreds of test showed blood-lead levels that were much higher than so-called "EPA action levels" for three years, the EPA admitted to knowing about the "massive" lead problem "a few months" before the public knew, according to Salon News. "At first we didn't think it was a big problem and WASA for the most part complied with the rules," Rick Rogers, who supervised EPA's work on the lead crisis in Washington, told Salon.

The parents of young twins, who believe lead exposure caused developmental problems with their children, filed a $200m lawsuit in February.

Study shows flat chests hit fertility rate

The conclusions about fertility below are inferential rather than direct but are plausible

THE modern generation of women, with successful careers and high stress levels to match, could find their super-powered lifestyle is affecting their fertility. An international comparison of women in 37 different populations and cultures shows that career women are more likely to look like Keira Knightley than Marilyn Monroe, even though the hourglass figure has previously been linked with improved fertility.

The research, published in the recent issue of the journal Current Anthropology, examines the shape of women around the world by comparing their waist-to-hip ratio, which is calculated by dividing a woman's waist circumference by the circumference of her hips.

University of Utah anthropologist Professor Elizabeth Cashdan says there is evidence the hormonal profile linked to a slim-waisted, non-curvy shape favours women in "resource competition, particularly under stressful and difficult circumstances".

The study suggests women who experience heavy work stress and are driven to succeed suffer a hormonal shift with their oestrogen levels affected by increases of androgens, hormones linked to competitiveness and strength.

Professor Cashdan says a small waist and large hips have significant fitness benefits for women. Those women with a waist-to-hip ratio of 0.7, meaning their waist is 70 per cent the size of their hips, are less prone to chronic disease and are typically considered to be more attractive. For a comparison, the study looks at the measurements of 240 Playboy centrefolds and finds they have an average waist-to-hip ratio of 0.68. The average female waist-to-hip ratio is 0.82.

Fertility Society of Australia president Professor Peter Illingworth says it is accepted that extremes in body shape can affect fertility. "If women are severely underweight or severely overweight, it affects the way that they ovulate and it affects their capacity to carry a child," he says.

He describes the anthropological findings as "interesting" and relevant on a wide scale. "I think we're looking at subtle effects across a whole population rather than an effect that would make a big difference of an individual woman's chances of having a baby."

Taxing soda to make you stop drinking it

The food police are closing in on their next target: a soda tax. New York City's health commissioner, Thomas Frieden, is leading the way. He's the guy who purged trans fats from the city's restaurants and made them post calorie counts for menu items. Lately he's been pressuring food companies to remove salt from their products.

Now he's going after soda. Writing in the New England Journal of Medicine, Frieden and Kelly Brownell, the director of Yale's Rudd Center for Food Policy and Obesity, propose a penny-per-ounce excise tax on "sugared beverages." That's nearly $3 per case. Why so much? Because this tax, unlike the petty junk-food taxes of yesteryear, is designed to hurt. Its purpose is to discourage you from buying soda, on the grounds that soda, like smoking, is bad for you.

Persuading Americans to regulate soda the way we regulate cigarettes won't be easy. Isn't soda a kind of food? Isn't food a good thing? And isn't it a matter of personal choice? Doesn't taxation to control people's eating behavior cross a fundamental line of liberty? In their article, Frieden and Brownell methodically attack these objections. Going well beyond science, they lay out a political battle plan for the war on junk food.

Step 1 is to convince us that soda isn't really food. If you think this can't be done, wake up: Frieden has already done it to trans fats. In the NEJM article, he and Brownell spurn the notion that soft drinks are sacred because "because people must eat to survive." They tartly observe that "sugared beverages are not necessary for survival."

Step 2 is to associate soda with products we already stigmatize and regulate as harmful. On this point, the authors quote Adam Smith: "Sugar, rum, and tobacco are commodities which are nowhere necessaries of life, which are become objects of almost universal consumption, and which are therefore extremely proper subjects of taxation."

Step 3 is to persuade you that one person's soda consumption harms others, thereby transcending personal liberty. The authors write: "The contribution of unhealthful diets to health care costs is already high and is increasing—an estimated $79 billion is spent annually for overweight and obesity alone—and approximately half of these costs are paid by Medicare and Medicaid, at taxpayers' expense. Diet-related diseases also cost society in terms of decreased work productivity, increased absenteeism, poorer school performance, and reduced fitness on the part of military recruits, among other negative effects."

The Medicare argument is dubious, since, as my colleague Daniel Engber points out, fat people die younger and thereby save the program years of coverage. But the really cheeky pitch is the one about military recruits. Apparently, Coke is now a menace to national security.

Step 4 is to target kids, because our urge to protect them makes us more amenable to paternalism. "Sugared beverages are marketed extensively to children and adolescents" and "now account for 10 to 15% of the calories consumed by children and adolescents," Frieden and Brownell observe. In fact, soda makers "exploit the cognitive vulnerabilities of young children, who often cannot distinguish a television program from an advertisement." New York Mayor Michael Bloomberg echoes this plea: "We have to do something to help our children."

Step 5 is to tempt policymakers with cash flow. "A third consideration is revenue generation," the authors note. "A penny-per-ounce excise tax would raise an estimated $1.2 billion in New York State alone."

Step 6 is to persuade voters that the tax is for their health, not for cash flow. Frieden and Brownell note the political importance of this message: "[A] poll of New York residents found that 52% supported a 'soda tax,' but the number rose to 72% when respondents were told that the revenue would be used for obesity prevention."

Three years ago, I thought the movement to legislate against junk food was politically futile. But that was before the successful assaults on trans fats, calorie counts, and opening fast-food restaurants. Those victories, apparently, were just the appetizers. The next course is behavior modification through taxation. And this article is the recipe.

Scientists find drug that destroys Alzheimer's protein

A NEW approach to treating Alzheimer's passed its first clinical test when a drug developed by scientists was shown to clear the brain of a damaging protein linked to the disease. The drug completely removed a protein called SAP from the brains of five Alzheimer's patients, suggesting that it may be a potential therapy for the incurable degenerative condition.

While the study was not designed to investigate whether the drug had therapeutic benefits, its results were so promising that the scientists behind it are now seeking up to £4 million ($8 million) to test it on a larger group. "There is a severe need for a treatment for Alzheimer's, and there is nothing available that works well," said Mark Pepys, of University College London, who is leading the research. "Nothing else looks promising at the moment, and this is a pretty good, safe option. We can't guarantee it will work, but it's got a good shot."

The drug, known as CPHPC, was first developed by Professor Pepys almost 10 years ago as a possible treatment for amyloidosis, a disease in which amyloid proteins accumulate in the body's organs, often with fatal results.

While Professor Pepys is still investigating the drug for this purpose, and has signed a deal with GlaxoSmithKline to develop it, he is also pursuing it as a possible Alzheimer's therapy. Alzheimer's also features the build-up of amyloid plaques, in this case in brain cells, making CPHPC a good candidate for treatment.

In the new study, published in Proceedings of the National Academy of Sciences, CPHPC was given to patients aged between 53 and 67 who had mild to moderate Alzheimer's disease. After three months the drug cleared all SAP from their brains. The study was too short to show whether this had any clinical effect but none of the patients deteriorated during the research period. "The complete disappearance of SAP could not have been confidently predicted, and the drug, also to our surprise, entered the brain," Professor Pepys said.

Martin Rossor, of UCL Institute of Neurology, who also worked on the research, said: "The safety of CPHPC, together with the novel action of the drug in removing SAP, is very encouraging."

The anti-fat fat man



Kelly Brownell, grandfather of the Twinkie Tax and author of the recent book Food Fight, regularly attacks restaurants and food suppliers for providing the food that Americans want: "The classic dodge of the food industry now is to blame the obesity problem on physical activity or lack of personal responsibility," he asserts. Brownell has said he wants to "get away from these arguments about personal responsibility." Yet when it comes to his own weight, the AP reports:
He sports a good-size paunch thanks, he says, to a book project that has kept him relatively sedentary and snack-prone for the last year or so. In photographs taken a few years back, Kelly Brownell looks much trimmer.

Brownell demonstrates the same disregard for parental responsibility that he exhibits for personal responsibility. In Food Fight, he writes that relying on parents is a "failed experiment" and implies parents can't be trusted to care for their own children any more than if they were trapped animals. He testified to Congress in 2002: "If children have healthy foods available, they'll eat healthy foods. If they have unhealthy foods available, they'll eat those ... Animals will do the same thing when put in a cage." Big Brother Brownell would rather trust government restrictions to manage what children eat.

Brownell also supports obesity lawsuits. In a statement announcing the Public Health Advocacy Institute's 2004 "Legal Approaches to the Obesity Epidemic" conference (the 2003 event was "intended to encourage and support litigation against the food industry"), he endorsed lawsuits as another way to control everyone else's behavior. And, trying once more to remove food from the realm of personal responsibility, he moderated a panel at the 2004 conference titled: "Are Some Foods Addictive?"

"Zoning laws," Brownell writes in Food Fight, should be used to "prohibit the operation of businesses selling food within a certain distance of schools." Brownell also recommended in the newsletter of the Puritanical Center for Science in the Public Interest that activists "develop a militant attitude about the toxic food environment, like we have about tobacco." (Will Brownell develop such a militant attitude about his own "toxic" environment at home that caused his own issue?) And what about consumers' freedom to eat what they please? Nonsense, says Brownell. Even smoking "became so serious that society overlooked the intrusion on individual rights for the greater social good."

Of course, Brownell uses Food Fight to heavily promote (what else?) taxes on foods he doesn't like. So he wants to "hit junk-food junkies where it hurts: in their wallets." Consumer taxes, he argues, "can generate considerable revenue and appear to drive down sales of these foods ... The aim of the taxes to decrease consumption of unhealthy foods must be made explicit."

Attacks on "unhealthy" snacks may be trademark Brownell, but even he admits: "No good foods, no bad foods may be true for an individual." That's the position of nutrition professionals, but Brownell argues "from a public health point of view" that "no good foods, no bad foods is a highly unproductive philosophy." Why? "Because it makes all food equal." That makes it harder for Brownell's band of food cops to push their hefty taxes on our tasty snacks.

Brownell's book includes a few remarkable admissions. Speaking of food marketing, he concedes: "There is only circumstantial evidence that the ads cause poor eating." But lack of good science doesn't stop him from complaining about advertising for applesauce and 100 percent juice drinks.

Brownell even acknowledges that being overweight isn't necessarily a health risk:
Groundbreaking work on fitness and weight has been done by [epidemiologist Steven] Blair and colleagues at the Cooper Institute. They have shown that the advantages of being fit are striking and that people can be fit even if they are fat ... and thus have lowered risk of disease. A remarkable finding is that heavy people who are fit have lower risk than thin people who are unfit.

'Double whammy' malaria drug hope

A new "double whammy" malaria drug which works on its own and reverses resistance to other drugs is being developed by US researchers. The drug contains a chemical which prevents the malaria parasite getting rid of a toxic by-product of feeding on red blood cells. It also disables a genetic defence that prevents the existing drugs chloroquine and quinine working, Nature reports. But the team says it could be at least 10 years before the drug is available.

There are around 250 million cases of malaria and 880,000 deaths worldwide each year.

The drug, developed by Jane Kelly and colleagues at Portland State University, is called an acridone derivative. It targets the way mosquitoes digest haemoglobin in red blood cells, from which they take amino acids as their food. A substance called haem, a by-product of this process, is toxic to the malaria parasites, carried by mosquitoes, so they have to convert it into a pigment called haemozoin. This drug prevents that conversion taking place, meaning the toxic pigment remains.

It is the same effect as that of chloroquine and quinine. But the researchers have found that, as well as working on its own, the acridone can restore and enhance the effectiveness of these other drugs too. Malaraia parasites have developed a genetic mutation preventing chloroquine and quinine absorption, and expelling them from the parasite's body. This new drug is able to disable that defence mechanism, allowing the chloroquine and quinine to do their job.

The researchers have successfully tested the compound in the lab and on mice, however they need to do more animal studies on the safety and effectiveness of the drug before they move on to human studies. It is also relatively inexpensive to make and has so far appeared to be safe in tests.

Dr Mike Riscoe from Portland State University who worked on the study, said: "What we wanted was to design a molecule that would be of itself an antimalarial drug, but that would have the power to work together with drugs like chloroquine and quinine, even against parasites that were resistant to those drugs. "We would hope to make existing drugs like chloroquine and quinine useful again, so combining those with this new one could help to combat the rising tide of drug resistance in this neglected disease.

But Dr Jane Kelly, who led the research, warned: "In the pharmaceutical industry, it can take 10 years and $1bn for a drug to be usable in humans, so we are still a long way away from that."

Surgical treatment 'can cure high blood pressure'

Is this another example of a medical miracle that eventually turns into an iatrogenic disaster? It may be treating a symptom rather than curing the cause

A surgical treatment for high blood pressure could cure millions of sufferers without the need for powerful drugs. The operation appears to permanently alleviate the chronic condition, which affects about a third of all adults in the UK and is a major cause of strokes and heart attacks.

It works by destroying bundles of nerves that line the artery supplying blood to the kidneys. In some people these nerves are thought to encourage the kidneys to retain salt, which contributes to high blood pressure. Doctors have developed a technique to blast the nerves with concentrated radiowaves to stop them from working. Clinicians found this had an almost immediate effect in lowering blood pressure. The effects were still apparent in patients 12 months later.

Most of the 50 patients in the Australian trial had dangerously high blood pressure but multiple drugs to control their condition had not worked. Experts claim that if further trials are as successful, most patients could benefit from the operation, known as radio frequency ablation and reported in The Lancet. It could be available in two years.

How the shape of your brain shows what kind of personality you have

Was phrenology right after all? Psychologists have long known that personality is highly hereditary so the findings below are not very surprising

Scientists may one day be able to find out what a young child’s personality will be like by simply scanning their brain, new research has shown. New research has found that the shape of your brain gives a clue to what type of person you are.

The differences in the shape of the brains of 85 people were scanned and measured. They found that larger or smaller amounts of tissue in certain areas of the brains were linked to specific personality traits. The discovery raises the startling possibility of being able to discover a young child’s future personality by analysing the shape of their brain.

The four main personality types were classified by psychiatrists as ‘novelty-seeking’, ‘harm avoidance’, ‘reward dependence’ and ‘persistence’. Those with a novelty-seeking personality had an area of the brain above the eye sockets which was larger than in other people, according to Professor Annalena Venneri of the University of Hull. ‘Novelty seekers’ were likely to act impulsively while those bracketed in the harm avoidance group were usually pessimistic and shy.

Those who were hard-working were part of the ‘persistence’ group while inveterate gamblers with an addictive personality were likely to be part of the ‘reward dependence’ category. People with ‘reward dependence’ personalities had brains with far less tissue in the fronto-striatal section of the brain. Damage to the fronto-striatal area is often linked to autism.

People with harm-avoidance personalities had significantly smaller volumes of tissue in brain regions called the orbito-frontal area and the posterior occipital region. The research suggests that children are born with certain personalities and also indicates that their brain develops differently depending on the type of person they become.

Children who eat porridge for breakfast 'get better exam results'

Seeing I had porridge for breakfast every day until I was 16, I am inclined to agree with this article -- but it wasn't REAL porridge studied below. The study is utter crap anyway. If it shows anything, it shows that correcting nutritional deficiencies is helpful -- not exactly news. Could the fact that "Children received supplements" just somehow be relevant??

Feeding children high energy breakfast foods such as porridge at a young age boosts their exams results at school, new research suggests. Children who followed such a diet before their third birthday had improved scores in reading and problem-solving tests compared to their peers, it was revealed.

In a study that provides some of the strongest links yet between nutrition and academic performance, academics said it also increased the likelihood of remaining in education for longer. It had a particular effect on girls. Research has already shown that food rich in omega 3 such as fish improves reading, writing and spelling among children.

The latest study, based on research using a kind of porridge eaten in Guatemala but made with corn rather than oats, suggests a wider link between food and brain power. John Maluccio, lead author and assistant professor of economics at Middlebury College, Vermont, said: "Before this study, only limited evidence spanning childhood to adulthood existed to support claims about the long-term effects of early childhood nutrition. "This study confirms that the first three years of life represent a window of opportunity when nutrition programs can have lifelong benefits on a child's development, particularly in education."

The study was based on children in Guatemala eating "atole". It was made with corn, rather than the traditional British oats used in porridge, although they share high protein levels. It was mixed with dry skimmed milk and sugar. Children received supplements between 1969 and 1977, the study, published in the Economic Journal, said.

In 2002 and 2004, researchers returned to Guatemala and collected information on school results. Men and women who received atole as children achieved higher scores on reading comprehension tests and on non-verbal cognitive tests, it was revealed. Women taking part in the study were more likely to remain in education for another year.

The research was conducted in Guatemala by the Institute for Nutrition in Central America and Panama, Emory University, the International Food Policy Research Institute (IFPRI), the University of Pennsylvania and Middlebury College.

John Hoddinott, a co-author and IFPRI senior research fellow, said: "We have long known that nutrition interventions can provide significant benefits in terms of a child's health and development. "This study in Guatemala is important because it shows that improving nutrition in early childhood can have significant educational payoffs into adulthood."

Jacqui Lowdon, a paediatric dietician from the British Dietetic Association, said the food used in the study would have a similar protien content to normal porridge, but added that poor diet among the children tested may be responsible for the dramatic results. “We already know that good nutrition is important for long-term health and especially important for brain development in the first few years of life,” she said.

New scar treatment Avotermin may change the face of surgery

People left with unsightly scars from injuries or surgery may soon be able to tone down their blemishes with a new drug, research suggests. Tests indicate that the healing drug has the potential to reduce scarring when administered before a surgical operation or on existing scars if the suture is redone.

The drug, a synthetic cell-signalling agent called avotermin, is injected under the skin at the site of the wound before and after an incision is made or surgery is carried out on an existing scar. Results from the tests, published in The Lancet, show that it improved the appearance of scars noticeably – as judged by panels of lay volunteers and experts.

The scientists who led the study said that in some cases the drug reduced redness and "lowered" the scar, making it feel more like normal skin. In others, it improved scars to the point that they could be located only with temporary tattoo markers.

Earlier research had identified transforming growth factor beta3 (TGFbeta3), a cytokine signalling molecule that sends messages between cells, as a possible anti-scarring therapy.

Three trials were conducted on groups of volunteers who were given centimetre-wide puncture wounds in their arms. The incisions were deep enough to penetrate the skin to underlying muscle. Varying doses of avotermin, an artificial form of TGFbeta3, were injected at the wound site both before and 24 hours after injury. Scarring appearance was assessed using a 100-point scale. The higher the number given, the more noticeable the scar was judged to be.

Trial participants ranged widely in age and were split into two groups, one receiving the anti-scarring therapy and the other a dummy treatment. In two trials, lower doses of the drug improved scarring appearance by up to eight points after 12 months. A third trial using higher doses resulted in improvements of as much as 64 points. About a third of the participants experienced a high level of improvement, a third had slight improvement, and in a third of cases there was no change. No side effects were reported. Avotermin affected the orientation, density and thickness of the collagen fibres that cause scarring, the studies showed.

Professor Mark Ferguson, from the University of Manchester, said that the treatment suggested that major changes to scarring treatment were possible. He said that with 42 million Europeans and 43 million Americans undergoing surgery every year, it could be of enormous benefit, adding that a trial into revision surgery – when people have an existing scar recut and sewn up – was also under way. “Some people got a really dramatic effect, where the scar was almost imperceptible. We had to tattoo temporary markers to either end of the cut because 12 months later we couldn’t see where the scar was,” he said. “If the drug continues to work and be approved it could be used in surgeries, following trauma and burns, from road traffic accidents to elective surgery and cosmetic procedures.”

Professor Ferguson and his colleagues wrote in The Lancet paper that they detected “substantial differences in collagen organisation in some participants, with avotermin-treated scars more closely resembling the basket-weave pattern of normal skin”.

The researchers added: “With low doses injected locally around the time of surgery, avotermin is a well tolerated and convenient treatment. These studies suggest that avotermin has potential to provide an accelerated and permanent improvement in scarring.”

Brendan Eley, chief executive of the Healing Foundation, said that TGFbeta3 had been one of the "holy grails" of anti-scarring therapy for some time, and described the results as encouraging. “That the impact on scar formation is both structural and aesthetic is very promising. What impact these therapies could have on patients with complicated and potentially disfiguring wounds – that’s the exciting next step of this work which the clinical community will await with eager anticipation," he said.

Research shows sex can lead to good health and a longer life

What! It more likely shows that people in poor health are less likely to have sex. The usual Godlike certainty below that they just somehow KNOW the causal path

SEX can help fight flab, ward off colds and make you live longer. “There is definitely a correlation between health and sex. If you are healthier, you are going to have more sex," Jennifer Bass, of the British sex research centre The Kinsey Institute, said. “Making love provides a cardiovascular workout and floods the body with feel-good chemicals.”

A survey by the American Association Of Retired Persons has revealed that sex is associated with good health and a longer life, The Sun reports. Almost half of over-50s - 44 per cent - who described their health as excellent or very good had intercourse at least once a week. But just 20 per cent of those with only fair or poor health made love this often.

Also, men who have sex less than once a month are twice as likely to have a fatal heart attack than men who make love at least twice a week. “Sex is great for the cardiovascular system but how much you get out depends on how much effort you put in," The Sun's Dr Carol Cooper said. “If it’s not getting your heart racing, you’re doing it wrong. “Patients with heart problems sometimes worry about dying on the job, but that’s very rare. If you can manage two flights of stairs you are probably fit enough for sex.”

Because it boosts circulation, sex increases the supply of oxygen to cells and stimulates the activity of various organs and systems within the body. And a regular dose of sex is just as good as a trip to the gym or a session with a personal trainer. “Just 30 minutes of sex will burn around 200 calories, so if you have sex five days a week, that’s equivalent to two-and-a-half hours in the gym," The Sun's fitness expert Nicki Waterman said.

CA-MRSA - the killer in our midst

Worrying

Sean Fisher couldn’t see the armies of toxic bacteria deep inside his right thigh, killing off wave upon wave of white blood cells sent forth to defend him; he didn’t know that a battalion of invaders was charging straight for his lungs, but the 10-year-old felt so ill he probably wouldn’t have cared. He’d spent the night before vomiting violently and enduring painful cramps, cradled in the arms of his mother, Vicky, until dawn.

Only the afternoon before, this normally strong and fit boy had been shifting rocks on the family’s idyllic rainforest enclave in Wondecla, 90km southwest of Cairns, with his older brother, Jack, mum and older sister, Terri. Just a couple of hours afterwards he complained of a tingling and burning sensation in his leg, upon which Vicky noticed a mysterious red rash rising up. Perhaps an insect bite, she thought. But as the night advanced, she suspected it was something far more troubling.

Once daylight broke, the 41-year-old mother, whose husband was away working in the mines in Papua New Guinea, wasted no time. She helped her son, now limping badly and deathly pale, into the family wagon for the 30-minute drive to the nearest hospital at Atherton. By the time he was admitted he was complaining of chest pain, had a fever of 40.3 degrees and his skin was breaking out in dark red, swollen pustules. Meningococcal disease, Vicky fretted. But a battery of blood tests revealed little more than an infection running out of control, and with Sean’s condition deteriorating, baffled doctors transferred him to Cairns Base Hospital. There a doctor took a photograph of the rash engulfing his torso, scalp, face and ears.

After almost three days, with the microbe still unknown and medical options running out, Sean was airlifted to Mater Children’s Hospital in Brisbane where he was immediately wheeled to intensive care, hooked up to a ventilator and drip-fed the antibiotic of last resort, vancomycin. Doctors put his chance of survival at 30 per cent. “There was so much infection in his lungs,” says Vicky, “that his X-rays were white.” With hope draining away she fell to her knees in the hospital chapel, “pleading with God not to take my baby away.”

The head of intensive care, after receiving the results from a CT scan and further blood tests, rolled Sean on to his side to examine an abscess on his pelvis. Sean yelled in agony but the specialist had a diagnosis consisting of six strange letters: CA-MRSA, or community acquired methicillin-resistant staphylococcus aureus, a new super-bug that lives not in hospital wards but in the outside world.

“I’d never heard of it,” says Vicky. “I’d read about golden staph, but not MRSA or CA-MRSA.” After continuing on high-dosage vancomycin, Sean began to make a slow but steady recovery. When he was discharged from hospital five weeks later, he had only 30 per cent lung capacity and was learning to walk again. Only now, four months later, is Sean anywhere near being the active boy he once was.

It turns out Sean is one of the lucky ones. Sydney teenager Reis Gray wasn’t so fortunate. The strapping 190cm 17-year-old returned home from guitar lessons one Tuesday evening sniffling and feeling lethargic. The next day his mother, Julie, drove him to the local GP, who prescribed a course of antibiotics. When his colour didn’t improve over the next 24 hours, a worried Julie phoned her mother, a retired nurse, but Reis insisted, “I’m fine, Mum. I don’t feel any pain.”

But he wasn’t fine and on Friday morning Julie dragged him out of bed (“I just need to sleep,” he moaned) and drove him to the GP, who took his pulse and immediately called an ambulance. Just before Reis was intubated in accident and emergency at Westmead Hospital, he asked, “Am I going to be all right, mum?”

“Of course you are, sweetheart,” Julie replied without hesitation, genuinely believing that in a Sydney hospital in the 21st century, brimming with cutting-edge technology, that her healthy, outdoorsy son, who hadn’t been in a hospital since he was born, would make a swift recovery. But it was to be the last time she heard Reis’s voice.

Astonished doctors took one look at his X-rays and scheduled a double lung transplant – three-quarters of Reis’s lung tissue was missing, eaten away by the bug. But before any transplant they had to halt the runaway infection in its tracks. They launched a barrage of antibiotics against it but the infection shook them all off like confetti.

This bright, gregarious young man – who enjoyed footy, fishing, and jamming with his dad, Warren, in the garage – never regained consciousness. Which didn’t stop him battling his insidious assailant for 24 more days, until his heart finally gave out. “He was the baby of the family, the one who always made us laugh,” says Julie, who has two older children, Josh, 20 and Jessica, 23. “He had his whole life ahead of him.”

In the middle of the dining table where we are talking, Reis smiles back at us from a white-framed photograph, a handsome young man with a lick of chestnut hair tumbling over his forehead. On a mantelpiece opposite stands a shiny wooden box. Inside rest his ashes.

Traffic pollution can harm babies in the womb, claim researchers

Ho hum! This claim is a hardy perennial and so is the poor quality of the evidence that it is based on. Polluted areas are less prestigious and therefore cheaper and therefore inhabited by losers generally. And the findings bore that out. The researchers observed and rightly controlled for a lot of these "loser" characteristics in their sample -- but it seems likely that they did not get them all -- drug abuse, for instance. The cause of the less healthy babies is in the nature of losers (more risky behaviour etc.) -- not in the pollution

Exposure to traffic pollution during pregnancy could harm babies in the womb, a study shows. The risk of a delivering a baby of small weight rose significantly with each increase in pollution levels during the first three months and final three months of pregnancy. Researchers believe restricted fetal growth may be linked to traffic pollution or living close to a major road.

Epidemiologist Professor David Rich, of the University of Medicine and Dentistry of New Jersey, and colleagues said it was unclear how air pollution restricts fetal growth. Previous research suggests air pollution might alter cell activity - or cut the amount of oxygen and nutrients a baby receives while in the womb.

Prof Rich, whose findings are published online in the Journal of Epidemiology and Community Health, said: "A body of evidence is emerging from several countries on the adverse consequences of ambient air pollution on fetal/birth outcomes, including pre-term birth and fetal growth restriction."

The researchers based their findings on almost 336,000 births in New Jersey between 1999 and 2003 and daily readings of air pollution from monitoring points around the state from the US Environmental Protection Agency.

Mothers of small, and very small birth weight babies were more likely to be younger, less well educated, of African-American ethnicity, smokers, poorer, and single parents than mothers with normal birth weight babies. But levels of ambient air pollutants were linked to restricted fetal growth, even after taking account of these risk factors.

Prof Rich said: "These findings suggest ambient air pollution, perhaps specifically traffic emissions during early and late pregnancy and/or factors associated with residence near a roadway during pregnancy, may affect fetal growth.

"Further, pregnancy complications may increase susceptibility to these effects in late pregnancy."

Gwyneth Paltrow's Shampoo Cancer Link Claim Dismissed By Scientists

Another addled-brain "celebrity".

Gwyneth Paltrow has come under fire from health experts after she warned shampoo could be linked to cancer. Writing on her website goop.com, The Shakespeare In Love star explains her concerns arose after she read research about what she calls "environmental toxins", which are found in products such as shampoo and lotion. Paltrow claims that these toxins could be linked to a rise in diseases such as asthma and cancer in children, and warns pregnant women to be careful.

She writes, "Fetuses, infants and toddlers are basically unable to metabolize toxins the way adults are, and we are constantly filling our environment with chemicals that may or may not be safe."

However, leading bacteriologist Professor Hugh Pennington has slammed her claims, describing them as "loopy." He says, "It does annoy me when celebrities use their position to spout nonsense. They have a perfect right to their views, even if they are loopy, but they do hold a position of influence."

Other experts at British charity Cancer Research UK have also dismissed Paltrow's theories, claiming there is no evidence to support her assertion that childhood cancer rates had increased "exponentially."

Bacon sandwich really does cure a hangover

A bacon sandwich really does cure a hangover - by boosting the level of amines which clear the head, scientists have found



Researchers claim food also speeds up the metabolism helping the body get rid of the booze more quickly. Elin Roberts, of Newcastle University's Centre for Life said: "Food doesn't soak up the alcohol but it does increase your metabolism helping you deal with the after-effects of over indulgence. So food will often help you feel better.

"Bread is high in carbohydrates and bacon is full of protein, which breaks down into amino acids. Your body needs these amino acids, so eating them will make you feel good."

Ms Roberts told The Mirror: "Bingeing on alcohol depletes neurotransmitters too, but bacon contains a high level of aminos which tops these up, giving you a clearer head."

Researchers also found a complex chemical interaction in the cooking of bacon produces the winning combination of taste and smell which is almost irresistible. The reaction between amino acids in the bacon and reducing sugars in the fat is what provides the sandwich with its appeal.

Ms Roberts said: "The smell of sizzling bacon in a pan is enough to tempt even the staunchest of vegetarians. There's something deeper going on inside. It's not just the idea of a tasty snack. There is some complex chemistry going on. "Meat is made of mostly protein and water. Inside the protein, it's made up of building blocks we call amino acids. But also, you need some fat. Anyone who's been on a diet knows if you take all the fat from the meat, it just doesn't taste the same. We need some of the fat to give it the flavour."

She explained that the reaction released hundreds of smells and flavours but it is the smell which reels in the eater. "Smell and taste are really closely linked," she said. "If we couldn't smell then taste wouldn't be the same."

Institute of Cancer Research finds melanoma gene trigger

Not those wicked genes again! The Left would surely tell us that it is all due to "poverty"

MOST melanoma skin cancers may be triggered by a gene mutation that causes cells to become cancerous after excessive exposure to the sun. The discovery could lead to better treatments for the most deadly form of skin cancer after scientists at Britain's Institute of Cancer Research established the BRAF gene mutation is often the first event in the cascade of genetic changes leading to melanoma.

Scientists already knew the BRAF gene was frequently damaged in patients with melanoma, but it was unclear if this was a cause or effect of the cancer.

The British institute published its findings in the journal Cancer Cell. "Our study shows that the genetic damage of BRAF is the first step in skin cancer development," said lead author Richard Marais. "Understanding this process will help us develop more effective treatments for the disease."

The hope is that knowing the genetics behind skin cancer will lead to the development of targeted drugs that can fix the faulty genetic machinery.

While melanoma accounts for only a small percentage of skin cancers, it is responsible for most skin cancer deaths. The disease is characterised by the uncontrolled proliferation of pigment-producing skin cells called melanocytes. Over-exposure to sunlight is to blame for at least two-thirds of cases as DNA in sunburnt skin cells becomes damaged, leading to the genetic mutations.

Hay fever 'could be cured by sex', say Iranians

Wishful thinking?

Hay fever symptoms could be alleviated by sexual intercourse, scientists have hypothesised, while admitting their recommendation does suffer from practical obstacles.

Researchers claim that sex constricts the blood vessels which unblocks bunged up noses and clears streaming eyes. Iranian scientists found the nasal system is linked to the reproductive system. So far experts at the Tabriz Medical University have not performed clinical trials to test their theory.

But if they are proved right then male sufferers need no longer rely on antihistamine drugs, some of which have been known to cause high blood pressure and blocked noses.

Neurologist Sina Zarrintan claims his method would be a lot more pleasurable, cheaper and need only be done whenever the symptoms become really bad. He said: "It can be done from time to time to alleviate the congestion and the patient can adjust the number of intercourses depending on the severity of the symptoms."

Not everyone agrees though. Mohammed Amin Abolghassemi Fakhree from Tabriz University poured scorn on the idea. He added: "There are some limitations in using ejaculation as a treatment of nasal congestion, such as not being applicable out of home and not having any sex partner."

Last night a lipstick saved my life: How a spot of lippy could prevent a fatal fall

Says cosmetics company. Maybe women who are healthy have more incentive to take care of their appearance and so would have fewer falls whatever they did

It may infuriate their waiting husbands, but women who insist on applying make-up before going anywhere could be saving themselves from disaster. Scientists have found that the ritual of applying lipstick and blusher acts as a type of stretching exercise which can improve balance and coordination. This is particularly important for older women, for whom a fall can cause serious injury or even death. Each year, more than 700,000 people over 65 in the UK have to go to hospital after a fall. Those who break a hip have a 20 per cent chance of dying within a year and falls are the leading cause of death for the over-75s.

The apparent benefits of make-up emerged from a study of 100 women from 65 to 85 at the University of St Etienne in France. They were fitted with special insoles to test their centres of gravity and a belt to monitor their posture. The researchers found that those who put on make-up every day had much better balance and posture, and suffered fewer falls.

Dr Patricia Pineau, who led the study, said: 'These women stood up straight and suffered fewer falls. They held themselves differently to those who did not wear make-up.' Dr Pineau, director of research communications at the cosmetics company L'Oreal Group, added: 'It could help to prevent many debilitating falls.' The findings are to be presented at the World Congress of Gerontology in Paris. Last year, a study concluded that gentle yoga exercises can cut the risk of painful falls in old age.

Just two months of classes improved muscle strength, balance and flexibility, making falls and fractures less likely. Women who took part in the programme of exercises, designed specifically for over-65s, also felt more confident, the U.S. research found. Even if falls do not cause broken bones or head injuries, they can leave older people fearful and dependent on others for everyday chores.

One reason the elderly are most at risk is that the nerves most distant from the brain, such as in the foot, tend to decline in activity as part of the ageing process. Damage from a fall is often made worse by underlying osteoporosis, the brittle bone disease.

Could taking Vitamin E harm your baby's heart?

Oh no! This cannot be! Vitamin E is one of those miraculous "antioxidants". Seriously, though, a 900% increase in risk makes it seem like a real hazard. Epidemiologists regularly go ga ga over a 30% increase in risk -- or less. But the "high" and the "safe" doses in the study differ only slightly so it is all a bit mad. I don't think the case is proven at all. But for once I endorse the official advice (at the end of the article). Journal abstract here

Pregnant women have been warned that taking even modest amounts of vitamin E can dramatically increase the risk of heart defects in babies. Expectant mothers who consume only three-quarters of the recommended daily amount of the vitamin, either through food or supplements, have up to nine times the risk that their child will be born suffering a heart abnormality, a study showed. The same link between heart damage and vitamin E was seen in women who had taken similar levels of the vitamin in the month preceding conception. Last night leading obstetricians said women should avoid vitamin E supplements if they are planning to conceive or are pregnant.

Vitamin E, found in nuts, seeds, vegetable oils and eggs, is an antioxidant and is thought to help skin stay healthy and ease the misery of premenstrual syndrome.

During pregnancy it was previously thought to help protect against miscarriage. The recommended daily intake, according to EU rules, is 20mg a day. However researchers from the Erasmus MC, University Medical Centre, in Rotterdam found women who had taken over 14.9mg a day during the first two months of pregnancy were up to nine times more likely to have a child with a heart defect. This risk was repeated for women who had consumed more than 14.9mg a day in the month prior to conception according to the study, published in the British Journal of Obstetrics and Gynaecology.

The exact mechanism which could lead vitamin E to cause an increased risk of heart damage is not yet known, but experts believe it plays a crucial role in early fetal growth.

The study examined the diets of 267 women whose child was born with a heart defect and 324 women whose children were born healthy. Mothers whose children had a heart defect showed significantly higher dietary vitamin E intake, averaging 13.3 mg per day compared with 12.6mg. A total of 89 of these mothers - 32 per cent - had a daily vitamin E intake above 14.9mg. The study authors said the results demonstrate that a high maternal intake of vitamin E 'is associated with a 1.7 to nine-fold increased congenital heart defect risk'.

Last night an eminent obstetrician, Professor Stuart Campbell, said: 'This work has to be confirmed but I think there is enough evidence for the Government to advise pregnant women not to take vitamin E supplementation in pregnancy.' Another expert, Professor Andrew Shennan, said: 'I do not advise taking any extra vitamins - C or E - because we simply don't know if it is safe, particularly in pregnancy.'

However, Dr Carrie Ruxton, an independent nutritionist and scientific adviser to the Health Supplements Information Service, said vitamin E was an essential nutrient and it was 'premature' to recommend that pregnant women avoid foods and supplements containing it.

The Department of Health said pregnant women should supplement a healthy diet only with extra folic acid, to guard against spina bifida, and vitamin D, to boost bone strength.

Rude Prime Minister needs more meat?

Australian Prime Minister Kevin Rudd is on a weight-loss diet that cuts out red meat

CRITICISM of Kevin Rudd's outburst on a flight from Papua New Guinea is completely over the top, Treasurer Wayne Swan has said. The Prime Minister was forced to apologise for yelling at a 23-year-old Royal Australian Air Force (RAAF) female flight attendant because he was not served the meal he wanted during the flight to Australia in January.

Opposition frontbencher Julie Bishop said yesterday that Mr Rudd was a bully and his behaviour would be unacceptable in any Australian workplace. Ms Bishop said the incident was not just rude, it was sexist and Mr Rudd had abused his position in an unequal power relationship. "This is a very powerful man in a privileged position bullying a female defence member whose job it is to wait on the Prime Minister as he travels around the world on a taxpayer-funded private jet," Ms Bishop told ABC TV yesterday. "Bullying behaviour by the Prime Minister in particular towards a female member of our serving defence force is totally unacceptable. "The kind of bullying that reduced her to tears and ended up in an incident report being filed ... would not be accepted in any workplace across Australia. It reflects very badly on him." ....

Opposition frontbencher Nick Minchin said Australians were seeing the real Kevin Rudd, whom people in parliament were already familiar with. "He's been quite appropriately nicknamed Kevin Rude ... as a result of this episode," Senator Minchin said. "Those of us who work and live in Parliament House have known for years there's two sides to Kevin Rudd, and that behind closed doors he's prone to temper tantrums and this sort of belittling and very bad behaviour with his own staff.

In London, Mr Rudd attempted to play down the incident and pleaded for understanding. "As I said, we're all human - we all make mistakes, your Prime Minister included," he said.

But maybe there is another explanation. According to Karen Inge, head of nutrition at the Victorian Institute of Sport, iron deficiency was the reason behind Mr Rudd's rude behaviour. "If you cut down on red meat it can reduce your iron levels. The major role of iron is to carry oxygen in the blood. If you have low oxygen it makes you tired. It's not rocket science. You only have to look at a child who is tired to see how cranky they are. When you are tired you don't often react in the best way possible," Ms Inge said.

Different brain responses found in believers and non-believers -- to the advantage of believers

The very busy Michael Inzlicht is good at proving the obvious and the finding below is far from unexpected too. But there are some occasions when confirmation of the expected is useful and I think the study below falls into that category. Inzlicht is a Leftist and presumably Jewish Canadian so one can understand his obvious disappointment with his own findings below.

The original heading on this article was amusing: "Researchers find brain differences between believers and non-believers". If you did not read the article carefully, you could well be left with the impression that religious brains were structurally deficient -- which is not remotely what the research shows. That's not the fault of Inzlicht, however, just the usual hostility to religion that pervades the academy. The journal abstract is here


Believing in God can help block anxiety and minimize stress, according to new University of Toronto research that shows distinct brain differences between believers and non-believers. In two studies led by Assistant Psychology Professor Michael Inzlicht, participants performed a Stroop task - a well-known test of cognitive control - while hooked up to electrodes that measured their brain activity.

Compared to non-believers, the religious participants showed significantly less activity in the anterior cingulate cortex (ACC), a portion of the brain that helps modify behavior by signaling when attention and control are needed, usually as a result of some anxiety-producing event like making a mistake. The stronger their religious zeal and the more they believed in God, the less their ACC fired in response to their own errors, and the fewer errors they made.

"You could think of this part of the brain like a cortical alarm bell that rings when an individual has just made a mistake or experiences uncertainty," says lead author Inzlicht, who teaches and conducts research at the University of Toronto Scarborough. "We found that religious people or even people who simply believe in the existence of God show significantly less brain activity in relation to their own errors. They're much less anxious and feel less stressed when they have made an error."

These correlations remained strong even after controlling for personality and cognitive ability, says Inzlicht, who also found that religious participants made fewer errors on the Stroop task than their non-believing counterparts.

Their findings show religious belief has a calming effect on its devotees, which makes them less likely to feel anxious about making errors or facing the unknown. But Inzlicht cautions that anxiety is a "double-edged sword" which is at times necessary and helpful.

"Obviously, anxiety can be negative because if you have too much, you're paralyzed with fear," he says. "However, it also serves a very useful function in that it alerts us when we're making mistakes. If you don't experience anxiety when you make an error, what impetus do you have to change or improve your behaviour so you don't make the same mistakes again and again?"

Phony Anti-Meat Doctors Getting Desperate For Publicity

This morning, a Washington Post blogger gave fear-mongering vegans at the Physicians Committee for Responsible Medicine (PCRM) some long-overdue advice: “Lighten up!” Taking a page from their close friends at PETA, PCRM caught the attention of a major newswire this week with a publicity stunt involving a novelty cheeseburger at a minor-league baseball stadium in Michigan. The four-pound monster burger, said PCRM’s Susan Levin, shouldn’t be sold without a “dietary disaster” warning label. Because no one knows that eating 4,800-calorie burgers isn’t a healthy habit. Right.

The Post’s Jennifer Huget was not impressed:
Give me a break. I've got to think that PCRM has got bigger fish to fry…

Of course nobody's suggesting that monster burgers become a dietary mainstay. But this is clearly a prank, a silly attention-getting device. To suggest that it's likely to encourage widespread overindulgence in hypercaloric ground beef sandwiches is, I think, disingenuous. Seems health advocacy groups, like minor-league ball teams, sometimes need a bit of publicity.

I don't want to eat a big burger myself. But I defend other people's right to cram one in their face if they so choose.

PCRM looks silly indeed for ignoring the fact that Michigan’s minor-league fans are probably in on the joke with this gigantic burger. (For crying out loud, the thing has its own t-shirt.)

But Huget slightly misses the mark on one point: To PCRM, there are no bigger fish than getting Americans to stop eating meat. One shameless food scare, phony medical claim, and meaningless warning label at a time.

How a cup of hot chocolate could boost brain power and stave off fatigue

The flavanol religion again. It is much more likely that other things in chocolate -- such as the stimulant theobromine -- were responsible for any effect. It is an enduring wonder that so many researchers think they "just know" what the causal path is. But with only 30 students tested, the generalizability of the results is highly questionable anyway

It is supposed to be the perfect bedtime drink to send you off to sleep. But in fact, a cup of hot chocolate could be just the thing to peep you up, scientists say. Research shows that flavanols - plant chemicals abundant in dark chocolate - stave off fatigue and boost mental sharpness. It is thought that they widen blood vessels, boosting blood flow to the brain.

Psychologists asked 30 people to carry out a battery of mental arithmetic tests before and after having a flavanol-rich chocolate drink or a dummy beverage. They found the sweet drink boosted performance on one of the tests, which involved repeatedly subtracting the number three from a start point of between 800 and 999.

The flavanols also appeared to counteract the tiredness brought on by doing the intensive arithmetic, the British Psychological Society's annual conference heard. Researcher Crystal Haskell (CORR) said: 'We asked them about their mental fatigue and that increased but the cocoa offset that increase.'

The study, carried out at the Brain, Performance and Nutrition Centre at Northumbria University, also found that a 500mg dose of flavanols was more effective than a higher one. With this being equivalent to five bars of chocolate a day, the researchers are now trying to find out if lower levels would also be of benefit.

Flavanols belong to a group of compounds called polyphenols, which are also abundant in red wine, tea, olive oil, onions, leeks, broccoli and blueberries.

Co-researcher David Kennedy said: 'The amounts we were giving them were more than you would get from eating small amounts in diet but there is quite a bit of evidence showing that general consumption over time is protective against neurodegenerative disease and decline in cognitive function. 'The more fruit and vegetables and things containing polyphenols that you eat, the better for your brain.'

Other research has credited flavanols with cutting the inflammation linked to heart disease, and with reducing the odds of dangerous blood clots. They are also said to help keep diabetes and high blood pressure under control.

One of the key attractions for many is that chocolate simply makes us feel good - stimulating the release of chemicals more normally associated with sex and exercise. Researchers have even gone as far as to claim that the smell of chocolate alone can protect against colds.

But, sadly for chocolate lovers, the treat's high fat and sugar content means dieticians recommend it is eaten as part of a balanced diet, rich in less appealing foods such a brown rice, pulses and fruit and vegetables.

Sports drinks 'can be worse for your teeth than cola'

I think the last paragraph below is the most persuasive. To ignore the role of saliva is quite amazing

They may enhance your performance on the pitch but energising sports drinks won't do the same for your winning smile, scientists say. Researchers found that some juices and squashes are so acidic that they can weaken the teeth after just a few mouthfuls. Taking regular sips during one day is enough to weaken the surface of a tooth, the scientists warned. The effects are even worse if you brush your teeth straight after taking a swig. Powerade, Gatorade, Vitamin Water, SoBe Life Water and Propel Fitness Water were all found to cause damage.

The research follows the rising popularity of sports drinks such as Lucozade. High in sugars and acids, they are designed to replace minerals and liquid lost during exercise - and to boost the athlete's energy. But past studies have shown that many are more corrosive than cola.

Their ingredients can be problematic - mainly the citric and ascorbic acid added to improve flavour and prevent the drink going off. Acid erodes the tooth's enamel coating and trickles into the bone-like material underneath, softening the tooth. If left untreated it can cause severe damage - and even tooth loss, the New York University researchers found.

Professor Mark Wolff, who led the study, said: 'This is the first time that the citric acid in sports drinks has been linked to erosive tooth wear.' His team looked at the effects of a sports drink on cows' teeth, which closely resemble human teeth. Half a tooth was dunked in a sports drink, the other half in water. 'Five teeth were immersed in each drink for 75 to 90 minutes to simulate the effects of sipping on sports drinks over the course of the day,' said Dr Wolff. When compared, the fragment exposed to sports drink had a 'significant amount' of erosion and softening, they told the annual meeting of the International Association for Dental Research, in Miami.

Brushing teeth immediately after having a drink can make the problem even worse, as the softened enamel is much more vulnerable to abrasive chemicals found in toothpaste.

In 2004, British dentists found that fizzy drinks double the chances of a 14-year-old suffering tooth erosion, which is more serious than tooth decay. Decay occurs when sugar reacts with bacteria in plaque to attack the areas between, or on top of, teeth. Erosion happens when the smooth, hard enamel is eaten away by acids, exposing dentine, the substance that makes up the bulk of a tooth, or even its root.

Lucozade Sport said: 'Sports drinks are functional drinks designed to keep people hydrated and refuelled during exercise. To avoid any dental issues we advise that it is not sipped or swilled around the mouth, but swallowed quickly.' A spokesman for Gatorade's Sports Science Institute said: 'This study does not replicate real life as the teeth were studied outside of the mouth. 'Ohio State University conducted a real-life study, the most comprehensive to date, and concluded that there is no relationship between the consumption of sports drinks and dental erosion.'

How some girls are born to be anorexic: Eating disorder linked to brain abnormality

That it is just another obsessive/compulsive disorder (a psychosis) has long been obvious and psychoses do normally have an hereditary component

Thousands of girls may be born at risk of suffering anorexia, according to a study that could revolutionise treatment of the eating disorder. Most sufferers are predisposed to the condition because of the way their brains developed in the womb, it is claimed.

The research threatens to overturn decades of scientific orthodoxy holding that anorexia is primarily caused by social factors, such as the pressure to lose weight to emulate size zero models.

Charities say the findings raise the prospect of drugs being developed to treat anorexia. Alternatively, doctors could screen girls at the age of eight to assess risk and treat accordingly.

The study, led by Dr Ian Frampton, consultant in paediatric psychology at London's Great Ormond Street hospital, will be unveiled at a conference at the Institute of Education in the capital this week. Dr Frampton said: 'Our research shows that certain kids' brains develop in such a way that makes them more vulnerable to commonly-known risk factors for eating disorders - such as the size zero debate, media representations of very skinny women and bad parents.'

Dr Frampton's team tested more than 200 anorexia sufferers from Britain, the U.S. and Norway. Most were females aged between 12 and 25 being treated in private hospitals in Edinburgh and Maidenhead. The researchers found around 70 per cent had suffered damage to neurotransmitters - which help brain cells communicate - or had undergone other subtle changes in the structure of their brains.

One in every few hundred girls may be affected in this way, according to Dr Frampton. He said the condition is caused by random conditions, not poor maternal diet or environmental factors.

The 'imperfect wiring' of the brain is similar to that seen in people with dyslexia, depression or hyperactivity. Dr Frampton said: 'These findings could help us to understand a disease we don't know how to treat. 'Arguments that social factors, such as girls feeling under pressure to lose weight to look like high-profile women in the media, contain logical flaws because almost everyone is exposed to them, yet only a small percentage of young people get anorexia. 'Those things are important but there must be other factors, involving genetics and science, that make some young people much more vulnerable than others.'

Around 1.1million people are estimated to have an eating disorder in Britain, most commonly anorexia and bulimia. Susan Ringwood, chief executive of Beat, the eating disorders charity, said: 'It could pave the way for the first drugs to be developed to treat eating disorders, similar to the way that anti-depressants help rebalance the brain of people with depression. 'And it will help parents understand they aren't to blame. 'Parents always blame themselves when their child develops an eating disorder. [That used to be the case for autism too. Psychiatrists blamed "refrigerator mothers" for the disorder -- which multiplied the suffering of the entirely innocent mothers] 'But what we are learning more and more from research in this area is that some people are very vulnerable to anorexia.

'That is down to genetic factors and brain chemistry, and not them trying to look like celebrity models or suffering a major traumatic event early in their lives.' She added: 'This research is a key missing part of the jigsaw of our understanding of anorexia.'

INTERNET-SURFING workers relax: employees who regularly sneak a peek at Facebook or shop online during office hours could actually be boosting their productivity. Melbourne University's Dr Brent Coker says workers who surf the internet for leisure, known as 'Workplace Internet Leisure Browsing' (WILB), are more productive than those who don't.

A study of 300 employees found 70 per cent of people who used the internet at work engaged in WILB. "People who do surf the internet for fun at work - within a reasonable limit of less than 20 per cent of their total time in the office - are more productive by about nine per cent than those who don't,'' said Dr Coker, from the university's Department of Management and Marketing. "Firms spend millions on software to block their employees from watching videos on YouTube, using social networking sites like Facebook or shopping online under the pretence that it costs millions in lost productivity. However that's not always the case.''

Reading online news sites and searching for product information were rated among the most popular WILB activities, while playing online games and watching YouTube movies also ranked high. And if workers need an excuse for the lapse, they can put it down to a lack of concentration. "People need to zone out for a bit to get back their concentration. Think back to when you were in class listening to a lecture - after about 20 minutes your concentration probably went right down, yet after a break your concentration was restored,'' Dr Coker said. "It's the same in the workplace.

"Short and unobtrusive breaks, such as a quick surf of the internet, enables the mind to rest itself, leading to a higher total net concentration for a day's work, and as a result, increased productivity.''

But he warned excessive time spent surfing the internet could have the reverse effect. "Approximately 14 per cent of internet users in Australia show signs of internet addiction - they don't take breaks at appropriate times, they spend more than a 'normal' amount of time online, and can get irritable if they are interrupted while surfing.

"WILB is not as helpful for this group of people - those who behave with internet addiction tendencies will have a lower productivity than those without.''

JUNIOR MOMENTS

Amazing! A balanced research report that considers alternative explanations for its findings

Maybe it’s time to retire the “senior moment.” These lapses of memory during everyday life — losing your keys or your train of thought — are thought to be more common in older people.

Not so, researchers from the University of Waterloo in Canada report March 21 at the annual meeting of the Cognitive Neuroscience Society. Researcher Amanda Clark and her colleagues surveyed 30 adults younger than 25 and 24 people ages 60 to 80 to find out how many slips they make each day.

The researchers also devised two lab tests to study attention. One involved pushing a button every time a number appeared on a computer screen, unless the number was three. That test helps researchers determine how often the mind wanders away from a task. The second test involved pushing buttons arranged in a diamond shape in a particular sequence. The exercise mimics a routine, such as making coffee. Once the volunteers learned the routine, the researchers tried to throw participants off by introducing changes in the routine.

Younger people made more errors on the routine-mimicking test than older people did. Younger adults also reported having more “senior moments” in daily life.

The results from reported “senior moments” could mean that older people have developed strategies to protect themselves from lapses in memory and attention, such as keeping keys in the same place, Clark says. In the tests, older adults go slower than their younger counterparts, which may be a form of coping and may improve accuracy. But Clark is not ready to rename memory and attention lapses “junior moments” just yet. Older adults may not report lapses in daily life for fear of being diagnosed with dementia or other illness, or they may not be aware when they make these mistakes.

Siblings benefit from sister presence

Sounds reasonable. Peer pressure is the strongest socialization agent and girls are very sensitive to peer pressure

GROWING up with a sister makes people more balanced, ambitious and optimistic, research suggests. A study of 571 families comprising brothers, sisters, a mixture of both and single children found that having a sister in the home led to siblings of either sex scoring more highly on a range of standard tests for good mental health.

They were found to be better at coping with setbacks and more highly motivated than those who grew up with just brothers. They also had more friends and a better social life.

The research, to be presented today at the British Psychological Society's annual conference in Brighton, was conducted by psychologists at De Montfort University in Leicester and the University of Ulster.

Liz Wright, a research fellow at De Montfort, said that the study began after previous research showed that girls with sisters appeared to experience less distress when they encountered trouble in their lives. "We wanted to see if the positive impact of sisters went farther than just girls and found that it did," she said. "One of the most interesting findings was the impact of female siblings when parents split up. It seems their natural inclination was to express themselves, talk about the separation and encourage other family members to do so as well. It seems to help keep family relationships going. There was markedly less distress in broken homes with a sister."

Psychologists have long believed that "emotional expression" at times of upheaval is fundamental to good psychological health. "Sisters appear to encourage that," Ms Wright said. "However, brothers seemed to have the opposite effect, perhaps discouraging others to talk."

The tests covered how much social support and control over their lives people felt they had, optimism, achievement motivation and ability to cope with setbacks.

The researchers said that the difference when a sister was in the home were "significant". It may help to explain the success of the Williams sisters, who have coped with huge upheaval and pressure in their lives on the professional tennis circuit.

The mental health of only children lay between that of children with a sister and those with only brothers. "It seems many only children had built up significant social support outside the home by the time they reached their late teens, which helped them in a crisis and in other areas of life," Ms Wright said.

The findings suggest that parents who separate should be aware that their sons may struggle to come to terms with the family break-up. The research will also be used in the treatment of eating disorders. The next research will seek to identify more precisely what sisters contribute to family life that makes such a positive difference.

Botox 'helps us be happy' by stopping the face from frowning

What extraordinary nonsense! For a start, how could they get statistical significance out of such a small sample? And the fact that Botox users might be different to start with seems to have been ignored

It is known for smoothing away the ravages of time. But Botox may also put a smile on your face. By stopping the face from frowning, Botox makes patients feel happier, a study suggests. Researchers believe our expressions affect our mood. So the wrinkling of the brow when annoyed reinforces our irritation. Botox paralyses the muscles we use to frown - leaving no option but to feel better.

Cardiff University psychologists looked at the effect of cosmetic treatments on the mood of 25 volunteers. Some had Botox to smooth their furrowed foreheads, others had laser surgery, cosmetic peels and other treatments designed to make them appear younger.

Both groups believed their treatment to be equally effective - but those given Botox were much happier. They were less anxious, irritable or depressed, the British Psychological Society's annual conference will hear today.

Researcher Michael Lewis said the mood differences between the groups was too great to be explained by the Botox patients being happier in general and was most likely to be a side-effect of Botox. Dr Lewis said: 'When you make an expression of happiness, it makes us feel happy. If we frown, it makes us feel sadder.' He said the research may help develop treatments for depressive illnesses.

Nigel Mercer, president of the British Association of Aesthetic Plastic Surgeons, said while Botox could possibly raise mood it would not be right to tell patients they would feel happier after treatment.

Ill-informed alcohol hysteria now being used by pocket dictators -- the characteristically ignorant "We know best" brigade

Mother-to-be is ordered out of a pub by staff concerned for health of her baby. Pregnant Caroline Williams was ordered out of her local pub after bar staff saw her sipping a friend's pint

A pregnant woman was refused a drink at a pub and then asked to leave by staff who said they were protecting her unborn child. Caroline Williams, 26, who is five months pregnant, says she felt humiliated by the treatment. She insists she is a responsible mother and would never endanger her baby.

The incident at the Cricketer pub in Hove, East Sussex, has reignited the debate on drinking during pregnancy. Advice from the Chief Medical Officer says that women trying to conceive or who are pregnant should avoid drinking alcohol. Excess alcohol consumption can be the cause of a condition known as Fetal Alcohol Syndrome which causes mental retardation and birth defects. But other experts say an occasional glass of wine will not harm a child.

Mrs Williams, who lives in Hove with her computer engineer husband Ben, 34, was at the pub with friends last Saturday. She said: 'I was on a rare night out with some friends. I had a pint of lager and a friend offered to get me another half - that was going to be my limit. 'He was refused service because it was for me and when I later took a sip from another friend's glass the assistant manageress asked me and my friends to leave. 'I never felt so singled out and humiliated in my life.

'I don't think what I did was doing any harm. This is my second baby and I'm feeling much more relaxed about this pregnancy than I did with my first. But I'm still very careful. 'I understand what the pub was thinking about but they didn't approach me to discuss it - they were just rude and ordered us out. 'I've never been ordered out of anywhere before and I'm not one to cause a scene, so we just left. 'I know the management has the right to refuse service but the assistant manageress was using that right to impose her opinions about what pregnant women should and shouldn't be consuming.'

Pubs have the right to refuse to serve customers and do not need to give a reason for doing so. An assistant manageress, who did not give her name, confirmed she had asked Mrs Williams to leave. She described her as 'a heavily pregnant lady who was drinking alcohol'. Another staff member defended the decision, adding: 'The assistant manageress was only thinking of the welfare of the mother and child.'

But a spokesman for the Mitchells and Butler chain which owns the pub apologised and said an investigation had been launched. He said: 'We would like to apologise unreservedly to all of the guests involved for any offence that may have been caused. While the team member may have believed she was acting with her own good intentions, she did not handle the situation in an appropriate manner.'

Since May 2007, the Health Service has advised women to avoid alcohol completely. This is in line with the U.S., Canada, Australia, New Zealand and France. But in October 2008, a large-scale study was published showing no link between having the occasional drink during pregnancy and behavioural problems in the child. And GPs often advise women that one or two drinks a week will not be a problem.

The National Organisation of Fetal Alcohol Syndrome said the action by the pub staff was heavy-handed. The group's founder Susan Fleisher said: 'We believe pregnant women need understanding and support to change their habits.'

'Super pill' could halve heart risks?

The papers are full of this bit of speculation. The theory is an old one but what is reported below proves nothing. You take blood-pressure-lowering drugs and cholesterol-lowering drugs and your blood pressure and cholesterol levels fall. Big surprise! The authors are only TALKING about the effect on mortality. They have no evidence on it. Given the side effects of statins in particular, the pill could INCREASE mortality. And a trial on people who already have heart disease tells you nothing certain about the general population anyway. Any benefit could well apply only to people with certain genetics, for instance

HEALTHY people may be able to cut their risk of heart disease in half by taking a "super pill" combining three drugs, a study says. The pill, which combines low doses of aspirin and two drugs to lower blood pressure and fight cholesterol, was compared to eight other therapies in the three-month study involving 2053 patients in India.

"The thought that people might be able to take a single pill to reduce multiple cardiovascular risk factors has generated a lot of excitement. It could revolutionise heart disease prevention as we know it," said principal researcher Salim Yusuf.

The Indian Polycap Study (TIPS) was the first to evaluate how well the polypill is tolerated and whether it leads to meaningful changes in the body. Carried out by St John's Medical College in Bangalore, the study recruited patients from 50 heart centres between March 2007 and August 2008.

Researchers found that by taking the pill healthy individuals might be able to cut their risk of cardiovascular disease by 50 to 60 per cent. "This trial is a critical first step to inform the design of larger, more definitive studies, as well as further development of appropriate combinations of BP lowering drugs with statins and aspirin," said Dr Yusuf.

The researchers found that the patients taking the polypill showed significant falls in cholesterol levels as well as in blood pressure.

The study, which will also be published in The Lancet, was unveiled at the 58th conference of the American College of Cardiology which has been meeting since Saturday in Orlando, Florida.

A vision of our fat future

The British writer below is acute enough to recognize that being fat is mostly genetic but unfortunately buys into the myth that being fat is unhealthy

Susan Ringwood, chief executive of Beat, the eating disorders charity, says those who overeat are, in many cases, as worthy of concern as those who undereat, but for obvious reasons don’t get as much attention as skeletal teenage girls who look almost like size-zero models.

“Overeaters know they are unhealthy. They know about their five a day but it’s no easier for them to make the long-term lifestyle changes to their diet than it is for anorexics,” she says. She also points out that when it comes to the spectrum of eating disorders, those who don’t eat, the anorexics, constitute only 10% – the tip of the iceberg. Most eat too much.

In the US they are way ahead of us. There, obesity has achieved the status of a “disease” even though it is caused by a combination of voluntary and involuntary factors: genes, sedentary lifestyles in the suburbs, the McDiet and an inability for various reasons to lose weight through exercise.

Stateside, the long-term effects and costs of what is regarded as the – sorry – ballooning obesity “epidemic” is the hottest issue in public health. Here, too, where two-thirds of us are carrying too many pounds of adipose tissue, we are beginning to wake up; the word “pandemic” has been applied to the nation’s thickening waistline by Brio, the Bristol University Research Into Obesity.

Dr James Le Fanu, the medical historian and GP, is one clinician who challenges the orthodoxy that chubsters have only themselves to blame. He thinks the cause of obesity is “not known”. He’s seen women on restricted diets failing to lose a single pound. His guess is that we all have thermostats, which govern our “energy balance” – how much weight we lose or gain relative to what we put in our mouths. He also believes that fatness runs in families, from observing this in his surgery.

This is the essence of the Chawner case, too. “We’re fat because it’s in our genes. Our whole family is overweight. Even when Philip went into hospital with septicaemia in 2006 he didn’t lose any weight. And he was eating tiny portions.”

Right, then. Fair enough. I am prepared to concede that being fat or being thin is partly in our DNA. But come on – it’s also a matter of choice, habit, lifestyle. It’s like smoking, drinking, sun-bathing – you can choose to gorge. Only, unlike smoking, which is in decline, more and more of us are “choosing” to be fat, or allowing our children to get fat, and that’s not good for any of us.

According to some estimates, obesity could cost the NHS in England £6.3 billion by 2015 unless the flab is fought. Some councils are having to shell out thousands of pounds on fat-friendly services, such as wider crematorium furnaces and bigger school chairs.

Whatever obesity’s cause, and however sympathetic we may or may not be, it doesn’t matter. Obesity is a national emergency. It is, yes, the new smoking. Rather than see them like animals in the zoo, we should commend the Chawner family freak show for displaying their bulk. They have drawn our horrified eyes to a health crisis that concerns us all.
