Katie Couric's Notebook: Bottled Water
2008-12-03, CBS News
Take a walk down the street or through the park and you'll see them – people of all ages toting bottles of water. Last year, Americans drank nine billion gallons out of those little plastic bottles. Sure, it's healthier than soda, but all that plastic is just as bad for the environment, creating an estimated 1.5 million tons of waste each year. So, more and more places are banning bottled water. Washington University in St. Louis will end almost all sales by the end of this semester. San Francisco declared it a no-no in city offices last year. Other local governments may do the same. Some brands, including Coca-Cola's Dasani and Pepsi's Aquafina, come from the tap – and supporters of these measures argue you're better off just filling a reusable container at the water fountain for free. A cheap, calorie-free alternative that doesn't hurt the environment. Now, I'll drink to that.

Standing in Someone Else’s Shoes, Almost for Real
2008-12-02, New York Times
Neuroscientists have shown that they can [create] a “body swapping” illusion that could have a profound effect on a range of therapeutic techniques. At the annual meeting of the Society for Neuroscience last month, Swedish researchers presented evidence that the brain, when tricked by optical and sensory illusions, can quickly adopt any other human form, no matter how different, as its own. “You can see the possibilities, putting a male in a female body, young in old, white in black and vice versa,” said Dr. Henrik Ehrsson of the Karolinska Institute in Stockholm. The technique is simple. A subject stands or sits opposite the scientist, as if engaged in an interview. Both are wearing headsets, with special goggles, the scientist’s containing small film cameras. The goggles are rigged so the subject sees what the scientist sees: to the right and left are the scientist’s arms, and below is the scientist’s body. To add a physical element, the researchers have each person squeeze the other’s hand, as if in a handshake. Now the subject can see and “feel” the new body. In a matter of seconds, the illusion is complete. In a series of studies, using mannequins and stroking both bodies’ bellies simultaneously, the Karolinska researchers have found that men and women say they not only feel they have taken on the new body, but also unconsciously cringe when it is poked or threatened. In previous work, neuroscientists have induced various kinds of out-of-body experiences using similar techniques. The brain is so easily tricked, they say, precisely because it has spent a lifetime in its own body.
FDA Draws Fire Over Chemicals In Baby Formula
2008-11-27, Washington Post
Public health groups, consumer advocates and members of Congress blasted the Food and Drug Administration yesterday for failing to act after discovering trace amounts of the industrial chemical melamine in baby formula sold in the United States. "This FDA, this Bush administration, instead of protecting the public health, is protecting industry," said Rep. Rosa DeLauro (D-Conn.), who chairs the Appropriations subcommittee that oversees the FDA budget. "We're talking about babies, about the most vulnerable. This really makes me angry."
The FDA found melamine and cyanuric acid, a related chemical, in samples of baby formula made by major U.S. manufacturers. Melamine can cause kidney and bladder stones and, in worst cases, kidney failure and death. If melamine and cyanuric acid combine, they can form round yellow crystals that can also damage kidneys and destroy renal function. Melamine was found in Good Start Supreme Infant Formula With Iron made by Nestle, and cyanuric acid was detected in Enfamil Lipil With Iron infant formula powder made by Mead Johnson. The FDA has been testing hundreds of food products for melamine in the aftermath of a scandal this year involving Chinese infant formula tainted with melamine. Chinese manufacturers deliberately added the chemical to watered-down formula to make it appear to contain higher levels of protein. More than 50,000 Asian infants were hospitalized, and at least four died.

Study Suggests Some Cancers May Go Away
2008-11-25, New York Times
Cancer researchers have known for years that it was possible in rare cases for some cancers to go away on their own. There were occasional instances of melanomas and kidney cancers that just vanished. And neuroblastoma, a very rare childhood tumor, can go away without treatment. But these were mostly seen as oddities — an unusual pediatric cancer that might not bear on common cancers of adults, a smattering of case reports of spontaneous cures. And since almost every cancer that is detected is treated, it seemed impossible even to ask what would happen if cancers were left alone. Now, though, researchers say they have found a situation in Norway that has let them ask that question about breast cancer. And their new study, to be published Tuesday in The Archives of Internal Medicine, suggests that even invasive cancers may sometimes go away without treatment and in larger numbers than anyone ever believed. Robert M. Kaplan, the chairman of the department of health services at the School of Public Health at the University of California, Los Angeles, [is] persuaded by the analysis. The implications are potentially enormous, Dr. Kaplan said. If the results are replicated, he said, it could eventually be possible for some women to opt for so-called watchful waiting, monitoring a tumor in their breast to see whether it grows. “People have never thought that way about breast cancer,” he added. Dr. Kaplan and his colleague, Dr. Franz Porzsolt, an oncologist at the University of Ulm, said in an editorial that accompanied the study, “If the spontaneous remission hypothesis is credible, it should cause a major re-evaluation in the approach to breast cancer research and treatment.”

Boston launches flu shot tracking
2008-11-21, Boston Globe
Using technology originally developed for mass disasters, Boston disease trackers are embarking on a novel experiment - one of the first in the country - aimed at eventually creating a citywide registry of everyone who has had a flu vaccination. The resulting vaccination map would allow swift intervention in neighborhoods left vulnerable to the fast-moving respiratory illness. The trial starts this afternoon, when several hundred people are expected to queue up for immunizations at the headquarters of the Boston Public Health Commission. Each of them will get a bracelet printed with a unique identifier code. Information about the vaccine's recipients, and the shot, will be entered into handheld devices similar to those used by delivery truck drivers. Infectious disease specialists in Boston and elsewhere predicted that the registry approach could prove even more useful if something more sinister strikes: a bioterrorism attack or the long-feared arrival of a global flu epidemic. In such crises, the registry could be used to track who received a special vaccine or antidote to a deadly germ. "Anything you can do to better pinpoint who's vaccinated and who's not, that's absolutely vital," said Michael Osterholm, director of the Center for Infectious Disease Research & Policy at the University of Minnesota. "I wish more cities were doing this kind of thing." When people arrive for their shots, they will get an ID bracelet with a barcode. Next, basic information - name, age, gender, address - will be entered into the patient tracking database. There will be electronic records, too, of who gave the vaccine and whether it was injected into the right arm or the left, and time-stamped for that day.

State off course on 'personal genomics'
2008-11-02, San Francisco Chronicle (San Francisco's leading newspaper)
California officials recently ordered two "personal genomics" firms to cease and desist operations within the state. The companies eventually were allowed to continue operations - with a few more regulatory conditions - but why did the state demand that they shut down in the first place? Why would a state that regards itself as progressive and high-tech act to censor what we can know about ourselves? Though regulators may shut down unscrupulous firms, the services offered by Navigenics and 23andMe meet the highest standards of accuracy, validity and reliability. The laboratories employed by both companies are fully licensed and trusted by researchers around the world. These companies give individuals the ability to take a "snapshot" of their DNA. The state objected, determining that doctors are gatekeepers of the human body, and Californians need a prescription to access their genetic blueprint. Doctors have a powerful lobby in Sacramento, and these technologies directly threaten their profits. Personal genomics aims to empower the individual, not line the pockets of an elite medical establishment. This establishment believes that individuals cannot be trusted with their own genetic information. The genome is vast, complicated and poorly understood, the argument goes, and therefore customers could be inundated with raw information of little or no practical use. Forbidding us from looking at our genes because we don't yet understand them, however, is contrary to science, innovation and human nature.

BPA Ruling Flawed, Panel Says
2008-10-29, Washington Post
The Food and Drug Administration ignored scientific evidence and used flawed methods when it determined that a chemical widely used in baby bottles and in the lining of cans is not harmful, a scientific advisory panel has found. In a highly critical report ... the panel of scientists from government and academia said the FDA did not take into consideration scores of studies that have linked bisphenol A (BPA) to prostate cancer, diabetes and other health problems in animals when it completed a draft risk assessment of the chemical last month. The panel said the FDA didn't use enough infant formula samples and didn't adequately account for variations among the samples. Taking those studies into consideration, the panel concluded, the FDA's margin of safety is "inadequate". The panel is part of the Science Board, a committee of advisers to the FDA commissioner, and was set up to review the FDA's risk assessment of BPA. Many of the studies that the panel said the FDA ignored were reviewed by the National Toxicology Program, which concluded in September that it had "some concern" that BPA can affect brain and behavioral development in infants and small children. Officials at FDA, which regulates the chemical's use in plastic food containers, bottles, tableware and the plastic linings of food cans, accepted some of the criticism in the report. "FDA agrees that due to the uncertainties raised in some studies relating to the potential effects of low doses of bisphenol-A that additional research would be valuable," said spokeswoman Judy Leon. The agency has commissioned new research on BPA.

U.S. falls behind other developed countries in infant mortality
2008-10-16, Los Angeles Times
After a century of declines, the U.S. infant mortality rate barely budged between 2000 and 2005, causing the United States to slip further behind other developed countries despite spending more on healthcare, according to a report released Wednesday. The rate was 6.86 infant deaths per 1,000 live births in 2005, virtually unchanged from 6.89 in 2000. In 1900, the rate was 100 deaths per 1,000 live births. The United States dropped to 29th in the world in infant mortality in 2004, the latest year for which data are available from all countries, tying with Poland and Slovakia. The year before, it was 27th. In 1960, it was 12th. The report from the Centers for Disease Control and Prevention attributed the leveling off in mortality to a 9% increase in premature births over the same period and to stalled progress in saving the earliest preterm infants. Premature birth and low birth weight are by far the biggest causes of infant death. Infant mortality rates vary by race and ethnicity, from a high of 13.63 per 1,000 births for African American women to a low of 4.42 for Cuban Americans, according to the CDC report. Differences in socioeconomic status and access to medical care did not entirely explain the gap, the report said. Premature births are increasing, possibly tied to rising rates of obesity, diabetes and hypertension. What those conditions have in common is that they are preventable, and that ... is where the United States falls behind other developed countries.

Gift to Center Headed by FDA Panel Chairman Raises Questions
2008-10-13, Washington Post
A retired medical supply manufacturer who considers bisphenol A to be "perfectly safe" gave $5 million to the research center headed by the chairman of a Food and Drug Administration panel about to rule on the chemical's safety. The July donation from Charles Gelman is nearly 50 times the annual budget of the University of Michigan Risk Science Center, where Martin Philbert is founder and co-director. Philbert did not disclose the donation to the FDA, and agency officials learned of it when reporters asked about it. Gelman said he considers the chemical, which is used to make baby bottles and aluminum can liners, to be safe. He said he had made his views clear to Philbert in several conversations. Philbert denied that. Philbert's committee is expected to release its opinion this month. The decision of Philbert's committee is expected to have huge implications on the regulation and sale of the chemical in items such as baby bottles, reusable food containers and plastic wraps. Since the late 1990s, studies have linked bisphenol A to cancer, heart disease, obesity, reproductive failures and hyperactivity in laboratory animals. Gelman, a retired manufacturer of syringes and medical filtration devices, has fought against government regulation of pollutants for years. He is an anti-regulation activist and an outspoken supporter of organizations such as JunkScience.com, the Cato Institute and the Competitive Enterprise Institute that attack the credibility of government and academic scientists on such topics as global warming and hazardous chemicals.

US controls bird flu vaccines over bioweapon fears
2008-10-11, USA Today/Associated Press
Deep inside an 86-page supplement to United States export regulations is a single sentence that bars U.S. exports of vaccines for avian bird flu and dozens of other viruses to five countries designated "state sponsors of terrorism." The reason: Fear that they will be used for biological warfare. Under this little-known policy, North Korea, Iran, Cuba, Syria and Sudan may not get the vaccines unless they apply for special export licenses, which would be given or refused according to the discretion and timing of the U.S. Three of those nations -- Iran, Cuba and Sudan -- also are subject to a ban on all human pandemic influenza vaccines as part of a general U.S. embargo. The regulations, which cover vaccines for everything from Dengue fever to the Ebola virus, have raised concern within the medical and scientific communities. Officials from the U.S. Department of Health and Human Services and the Centers for Disease Control and Prevention said they were not even aware of the policies until contacted by The Associated Press ... and privately expressed alarm. They make "no scientific sense," said Peter Palese, chairman of the microbiology department at Mount Sinai School of Medicine in New York. Some experts say the idea of using vaccines for bioweapons is far-fetched.
When Doctors, and Even Santa, Endorsed Tobacco
2008-10-06, New York Times
People who remember when tobacco advertising was a prominent part of the media landscape ... probably recollect that actors like Barbara Stanwyck and athletes like Mickey Mantle routinely endorsed cigarettes. But how about doctors and other medical professionals, proclaiming the merits of various cigarette brands? Or politicians? Or children? Even Santa Claus? Those images — some flabbergasting, even disturbing — were also used by Madison Avenue to peddle tobacco products. An exhibit ... in New York presents cigarette ads from the 1920s through the early 1950s in an effort to demonstrate what has changed since then — and what may not have. The exhibit is the brainchild of Dr. Robert K. Jackler of the Stanford School of Medicine. “The very best artists and copywriters that money could buy” would work on cigarette accounts, said Dr. Jackler. “This era of over-the-top hucksterism went on for decades,” he added, “and it was all blatantly false.” The genesis of the exhibit was an ad from around 1930 for Lucky Strike cigarettes, which shows a doctor above a headline proclaiming that “20,679 physicians say ‘Luckies are less irritating.’ ” The Luckies doctor was joined in Dr. Jackler’s collection of about 5,000 ads by scores of scientists and medical professionals — doctors, dentists, nurses — making statements that are now known to be patently untrue. Some of the claims being made in the ads, you did not have to be a scientist in a laboratory to dispute ... ads that smoking certain brands “does not cause bad breath” or “can never stain your teeth.”
Note: The Journal of the American Medical Association (JAMA) promoted cigarette ads for 20 years "after careful consideration of the extent to which cigarettes were used by physicians in practice." Will people, even highly respected members of society, bend the truth and even lie when paid enough? This article seems to answer that with a resounding yes. Is that still true today?

Cancer risk in mobile phones: Official
2008-10-06, The Sun
Mobile phones DO increase the risk of brain cancer, scientists claimed yesterday. The chances of developing a malignant tumour are "significantly increased" for people who use a mobile for ten years. The shock finding is the result of the biggest ever study by the International Agency for Research on Cancer, part of the World Health Organisation. Scientists found a type of brain tumour called glioma is more likely in long-term mobile users. French experts analysed data from 13 countries, including Britain. They cross-referenced various types of tumours with mobile use. Researchers admit the cause is unknown, but it is thought radiation from handsets could be the trigger. Study chief Professor Elisabeth Cardis said: "To underestimate the risk would be a complete disaster." Last night a British expert insisted mobiles are not dangerous. Professor Patricia McKinney of the University of Leeds said: "Reasonable use is unlikely to increase the risk of tumours."

Scientists warn US Congress of cancer risk for cell phone use
2008-09-25, Breitbart News/Agence France Presse
Scientists on Thursday warned US legislators of the risks of brain cancer from cell phone use, highlighting the potential risk for children who use mobile phones. "We urgently need more research," said David Carpenter, director of the Institute of Health and Environment at the University of Albany, in testimony before the House Subcommittee on Domestic Policy. "We must not repeat the situation we had with the relationship between smoking and lung cancer," Carpenter said. Ronald Herberman, director of the University of Pittsburgh Cancer Institute, said that most studies "claiming that there is no link between cell phones and brain tumors are outdated, had methodological concerns and did not include sufficient numbers of long-term cell phone users." Many studies denying a link "defined regular cell phones as 'once a week,'" added Herberman. "I cannot tell this committee that cell phones are definitely dangerous. But, I certainly cannot tell you that they are safe," he said. Carpenter and Herberman both told the committee the brain cancer risk from cell phone use is far greater for children than for adults. Herberman held up a model for lawmakers showing how radiation from a cell phone penetrates far deeper into the brain of a 5-year-old than that of an adult. "Every child is using cell phones all of the time, and there are three billion cell phone users in the world," said Herberman. He added that, like the messages that warn of health risks on cigarette packs, cell phones "need a precautionary message."

Humble Honey Kills Bacteria
2008-09-23, CBS News
A new study from researchers at the University of Ottawa shows honey to be effective in killing bacteria that cause chronic sinusitis [which] affects millions of people every year. In chronic sinusitis, the mucous membranes in the sinus cavities become inflamed, causing headaches, stuffy nose, and difficulty breathing.
Though it can be caused by allergies, chronic sinusitis can also be caused by bacteria that colonize in the nose and sinuses. That's where honey may help. Researchers, led by Tala Alandejani, MD, at the University of Ottawa, tested two honeys, manuka and sidr. [They] singled out three particularly nasty bacteria: two strains of staph bacteria ... and one called Pseudomonas aeriginosa. The two types of honey were effective in killing the bacteria. Even bacteria growing in a biofilm, a thin, slimy layer formed by bacteria that affords resistance to antibiotics, were susceptible to honey. The researchers also found that the two types of honey worked significantly better than an antibiotic against [the staph bacterias]. Scientists hope the results can help lead to a new treatment for people with chronic sinusitis.
Note: One note of caution: Infants one year or younger should never be given honey because it could become toxic in their underformed intestinal tract, causing illness or even death.
Mobile phone use 'raises children's risk of brain cancer fivefold'
2008-09-21, The Independent (One of the U.K.'s leading newspapers)
Children and teenagers are five times more likely to get brain cancer if they use mobile phones, startling new research indicates. The study, experts say, raises fears that today's young people may suffer an "epidemic" of the disease in later life. At least nine out of 10 British 16-year-olds have their own handset, as do more than 40 per cent of primary schoolchildren. Yet investigating dangers to the young has been omitted from a massive £3.1m British investigation of the risks of cancer from using mobile phones, launched this year, even though the official Mobile Telecommunications and Health Research (MTHR) Programme – which is conducting it – admits that the issue is of the "highest priority". Despite recommendations of an official report that the use of mobiles by children should be "minimised", the Government has done almost nothing to discourage it.
Last week the European Parliament voted by 522 to 16 to urge ministers across Europe to bring in stricter limits for exposure to radiation from mobile and cordless phones, Wi-fi and other devices, partly because children are especially vulnerable to them. They are more at risk because their brains and nervous systems are still developing and because – since their heads are smaller and their skulls are thinner – the radiation penetrates deeper into their brains. David Carpenter, dean of the School of Public Health at the State University of New York said: "Children are spending significant time on mobile phones. We may be facing a public health crisis in an epidemic of brain cancers as a result of mobile phone use."

We can stop the cancer epidemic
2008-09-19, New York Times
There is an epidemic of cancer today. One in three Americans will be diagnosed with cancer, often before the age of 65. Since 1940, we have seen in Western societies a marked and rapid increase in common types of cancer. In fact, cancer in children and adolescents has been rising by 1 to 1.5 percent a year since the 1960's. And these are cancers for which there is no screening. For most common cancers - prostate, breast, colon, lung - rates are much higher in the West than in Asian countries. Yet Asians who emigrate to the United States catch up with the rates of Americans within one or two generations. While in Asia, Asians are protected not by their genes, but by their lifestyle. We continue to invest 97 percent of our cancer research funds in better treatments and early detection. Only 3 percent is invested in tackling causes. The World Cancer Research Fund published a report in 2007 concluding that a majority of cancer cases in Western societies could be avoided with life-style measures: 40 percent from changes in diet and physical activity (more vegetables and fruits, less sugar, less red meat, regular walking or the equivalent activity 30 minutes six times per week), 30 percent from smoking cessation, and about 10 percent from reduced alcohol consumption. We now even have data about how specific foods such as broccoli and cabbages, garlic and onions, green tea or the spice turmeric directly help kill cancer cells and reduce the growth of new blood vessels they need to develop into tumors.

Study Links Chemical BPA to Health Problems
2008-09-17, Washington Post
The first large study in humans of a chemical widely used in everyday plastics has found that people with higher levels of bisphenol A had higher rates of heart disease, diabetes and liver abnormalities. The research, published ... in the Journal of the American Medical Association by a team of British and American scientists, compared the health status of 1,455 men and women with the levels of the chemical, known as BPA, in their urine. The researchers divided the subjects into four statistical groupings according to their BPA levels and found that those in the quartile with the highest concentrations were nearly three times as likely to have cardiovascular disease than those with the lowest levels, and 2.4 times as likely to have diabetes. Higher BPA levels were also associated with abnormal concentrations of three liver enzymes. "This is the nail in the coffin," Frederick vom Saal, a reproductive scientist at the University of Missouri at Columbia and one of the first to document evidence of health problems in rodents exposed to low doses of BPA. "This is a huge deal." More than 100 studies have linked BPA exposure to health effects in animals. The FDA maintains that BPA is safe largely on the basis of two studies funded by the chemical industry, a fact that was repeatedly cited at yesterday's forum. "We're concerned that the FDA is basing its conclusion on two studies while downplaying the results of hundreds of other studies," said Amber Wise of the Union of Concerned Scientists. "This appears to be a case of cherry-picking data with potentially high cost to human health."

That Plastic Baby Bottle
2008-09-06, New York Times
What do you do when one arm of the government says everything is O.K. and another tells you to watch out? That is what is happening with bisphenol-A — a chemical used in many plastics and epoxy resins now found in baby bottles and liners for canned goods. The answer is a truism in every family rulebook — when in doubt, especially when it comes to children, err on the side of caution. That means it is a good idea to keep the young away from bisphenol-A, or BPA. Then this week, the National Toxicology Program, the federal agency for toxicological research, reported that their research shows “some concern” about the effects of BPA on the brain development and behavior of fetuses and young children. A new study by the Yale School of Medicine is cause for even more concern. In tests on primates, researchers found that BPA “causes the loss of connections between brain cells” that could cause memory or learning problems and depression.” John Bucher, the associate director of the toxicology program, said ... "We have concluded that the possibility that BPA may affect human development cannot be dismissed.”

Clones' Offspring May Be In Food Supply: FDA
Food and milk from the offspring of cloned animals may have entered the U.S. food supply, the U.S. government said on Tuesday, but [then claimed] it would be impossible to know because there is no difference between cloned and conventional products. The U.S. Food and Drug Administration said in January [that] meat and milk from cloned cattle, swine and goats and their offspring were as safe as products from traditional animals. Before then, farmers and ranchers had followed a voluntary moratorium on the sale of clones and their offspring. While the FDA evaluated the safety of food from clones and their offspring, the U.S. Agriculture Department was in charge of managing the transition of these animals into the food supply. "It is theoretically possible" offspring from clones are in the food supply, said Siobhan DeLancey, an FDA spokeswoman. Cloning animals involves taking the nuclei of cells from adults and fusing them into egg cells that are implanted into a surrogate mother. There are an estimated 600 cloned animals in the United States. Critics contend not enough is known about the technology to ensure it is safe, and they also say the FDA needs to address concerns over animal cruelty and ethical issues. "It worries me that this technology is out of control in so many ways," said Charles Margulis, a spokesman with the Center for Environmental Health.

Researchers Question Wide Use of HPV Vaccines
2008-08-21, New York Times
Two vaccines against cervical cancer are being widely used without sufficient evidence about whether they are worth their high cost or even whether they will effectively stop women from getting the disease, two articles in this week’s New England Journal of Medicine conclude. Both vaccines target the human papillomavirus, a common sexually transmitted virus that usually causes no symptoms and is cleared by the immune system, but which can in very rare cases become chronic and cause cervical cancer. The two vaccines, Gardasil by Merck Sharp & Dohme and Cervarix by GlaxoSmithKline, target two strains of the virus that together cause an estimated 70 percent of cervical cancers. “Despite great expectations and promising results of clinical trials, we still lack sufficient evidence of an effective vaccine against cervical cancer,” Dr. Charlotte J. Haug ... wrote in an editorial in Thursday’s issue of The New England Journal. “With so many essential questions still unanswered, there is good reason to be cautious.” The vaccines have been studied for a relatively short period — both were licensed in 2006 and have been studied in clinical trials for at most six and a half years. Researchers have not yet demonstrated how long the immunity will last, or whether eliminating some strains of cancer-causing virus will decrease the body’s natural immunity to other strains. Because cervical cancer develops only after years of chronic infection with HPV, Dr. Haug said there was not yet absolute proof that protection against these two strains of the virus would ultimately reduce rates of cervical cancer.
