Red clover: A powerful herb with strong healing properties

Every year, a beautiful crop of red clover spontaneously matures on my lawn. For a few weeks, the dark pink tops adorn the yard. I always look forward to the blooming of red clover, and I take advantage of the bumper crop in my yard by picking some and drying it for herbal tea. Originating from Europe, northern Asia and Africa, red clover is broadly distributed throughout the United Sates. As a fodder crop red clover is cultivated for animals, and the plant benefits soil by fixing nitrogen, thereby making it an ideal cover crop for enriching soil fertility for other crops. In the U.S., red clover is the state flower of pastoral Vermont. The use of red clover as an herbal remedy goes back centuries, and the plant enjoys a history of both topical and internal applications. As a topical aid, red clover is often an ingredient in liniments and balms, for relieving the pain of both eczema and psoriasis, for sores, burns, and as an aid against skin cancer. The pain-relieving properties of red clover are likely due to the presence of the anti-inflammatory compounds eugenol, myricetin and salicylic acid in the flowers. Salicylic acid also demonstrates activity against eczema. Red clover has long been used as a “blood purifier,” specifically for the potential treatment of cancer. The flower is a mainstay ingredient in traditional herbal formulas, including Essiac Tea, Jason Winters Tea, and the Hoxsey Therapy. In the best selling herbal classic Back to Eden, author Jethro Kloss declares red clover as a life-saving anti-cancer remedy. Proponents of these therapies claim a multitude of successes, while various health agencies including the FDA and the American Cancer Society declare these same formulas to be of no value. In red clover blossoms, the compounds biochanin-A, caffeic acid, chlorogenic acid, coumarin, formononetin, genistein and isorhamnetin all demonstrate some anti-cancer properties, according to various published studies. So the truth of red clover’s possible value for treating cancer likely lies between the positions of advocates and critics. One thing is certain: Red clover is a blood thinner. This is due to the concentration of coumarin found in the blossoms. For cases of thrombosis and other conditions in which thick blood obstructs vessels, red clover tea may be of benefit. However, for those who are taking blood-thinning medications, adding red clover to the mix can be a bad idea. Prior to surgery, drinking red clover is not recommended, as doing so may exacerbate surgical bleeding. Because of its concentration of the phytoestrogens daidzein and genistein, which mimic the activity of estrogen, red clover has been studied for its use in alleviating the discomfort of menopause. In one study reported in the Journal of the American Medical Association, the red clover-based product Promensil showed slightly better activity than a placebo for the relief of hot flashes – but overall the results were underwhelming. In general, red clover has not proven especially effective for menopausal discomfort. The same presence of phytoestrogens – plant compounds that mimic estrogen – has led many doctors to warn against using red clover preparations if women have had reproductive health disorders including endometriosis, uterine fibroids, or breast and uterine cancers. The concern is that the phytoestrogens may increase rather than alleviate these conditions. As a gentle cleansing tea drunk on occasion for overall salutary purposes, red clover appears to offer many benefits to health. High in natural protective antioxidants and anti-inflammatory compounds – and pleasant in flavor – red clover is good for general health, and is a tasty beverage. Rather than buying red clover tea in a store, just harvest a little from your lawn. Dry it on some newspaper for a few days, and you have red clover herbal tea, ready to go.Chris Kilham is a medicine hunter who researches natural remedies all over the world, from the Amazon to Siberia.

Vegetarian diet tied to fewer deaths over time

People who limit how much meat they eat and stick to mostly fruits and vegetables are less likely to die over any particular period of time, according to a new study. “I think this adds to the evidence showing the possible beneficial effect of vegetarian diets in the prevention of chronic diseases and the improvement of longevity,” said Dr. Michael Orlich, the study's lead author from Loma Linda University in California. In 2012, a Gallup poll found about 5 percent of Americans reported to be vegetarians. Previous research has found that people who eat mostly fruits and vegetables are less likely to die of heart disease or any other cause over certain periods of time. Another study from Europe, however, found British vegetarians were just as likely to die at any point as meat eaters, so it's still an “open question,” Orlich said. For the new study, he and his colleagues used data from 73,308 people recruited at U.S. and Canadian Seventh-day Adventist churches between 2002 and 2007. At the start of the study, the participants were asked about their eating habits and were separated into categories based on how often they ate dairy, eggs, fish and meat. Overall, 8 percent were vegans who didn't eat any animal products while 29 percent were lacto-ovo-vegetarians who didn't eat fish or meat but did eat dairy and egg products. Another 15 percent occasionally ate meat, including fish. The researchers then used a national database to see how many of the participants died by December 31, 2009. Overall, they found about seven people died of any cause per 1,000 meat eaters over a year. That compared to about five or six deaths per 1,000 vegetarians every year. Men seemed to benefit the most from a plant-based diet. Orlich cautioned, however, that they can't say the participants' plant-based diets prevented their deaths, because there may be other unmeasured differences between the groups. For example, Alice Lichtenstein, director of the Cardiovascular Nutrition Laboratory at Tufts University in Boston, said the participants who were vegetarians were healthier overall. “It's important to note that the vegetarians in this study were more highly educated, less likely to smoke, exercised more and were thinner,” Lichtenstein, who was not involved with the new study, told Reuters Health. Those traits have all been tied to better overall health in the past. Should you go veg? Dr. Robert Baron, who wrote an editorial accompanying the new study in JAMA Internal Medicine, said the new evidence doesn't mean everyone should switch to a plant-based diet. “I don't think everybody should be a vegetarian, but if they want to be, this article suggests it's associated with good health outcomes,” said Baron, professor of medicine at the University of California, San Francisco. Instead, he writes limiting added sugars, refined grains and saturated fats trumps whether or not to include a moderate amount of dairy, eggs, fish or meat. Previous research has found that people who were on a mostly plant-based diet still had lower cholesterol while eating a small amount of lean beef. “It's like everything else, you have to think about it in terms of the whole package,” Lichtenstein said.source : http://www.foxnews.com/health/2013/06/04/vegetarian-diet-tied-to-fewer-deaths-over-time/

Dispute flares within FDA over safety of popular blood pressure drugs

The top-selling class of blood-pressure drugs is under attack from an unusual source: a senior regulator at the Food and Drug Administration. Bucking his bosses, Thomas A. Marciniak is seeking stronger warnings about the drugs known as angiotensin receptor blockers, or ARBs, according to internal documents reviewed by The Wall Street Journal. The drugs, which are taken by millions of people and generated $7.6 billion in U.S. sales in 2012, may be linked to higher cancer rates, Dr. Marciniak argues, a view shared by some outside doctors. Top FDA officials say evidence doesn't support a link. The debate over ARBs highlights the question of whether the U.S. drug-safety agency devotes enough effort to examining the safety of long-marketed blockbusters as it focuses on new drugs. In a rare rebellion by an FDA reviewer, Dr. Marciniak has clashed with his bosses over his desire to spend time on ARB safety, instead of just on new-drug applications. Ellis Unger, chief of the drug-evaluation division that includes Dr. Marciniak, called the complaints a “diversion,” and said in an interview, “We have no reason to tell the public anything new.” ARBs on the market in the U.S. include Novartis AG's Diovan, Daiichi Sankyo Co.'s Benicar, Merck &#38; Co.'s Cozaar, Boehringer Ingelheim GmbH's Micardis; Avapro, from Sanofi SA and Bristol-Myers Squibb Co.; and AstraZeneca PLC's Atacand. Patients take these medicines daily to avoid heart attack, stroke and heart failure. In a 2010 study published in Lancet Oncology, Ilke Sipahi and colleagues at University Hospitals in Cleveland looked at five studies involving 68,402 patients and found that people taking ARBs had an 11 percent greater risk of new cancer overall and a 25 percent greater risk of new lung cancer, compared with patients who didn't get the drugs. But within a year, the FDA gave the all-clear signal, saying its own analysis found “no increase in risk” from taking ARBs. Europe's drug regulator also dismissed the cancer concerns. Dr. Marciniak wasn't persuaded. In its analysis, the FDA combined different studies to look at more patients, multiplying its statistical power to find possible side effects from the drugs, a technique called meta-analysis. If the original studies have flaws, however, meta-analyses can simply compound the problem, researchers say. That is what happened to the FDA, says Dr. Marciniak, who warned others in the agency that taking results tabulated by companies was likely to produce unreliable results: “Garbage in, garbage out,” he wrote. Among other things, Dr. Marciniak said in an internal analysis viewed by the Journal that the FDA meta-analysis didn't count cases of “lung carcinomas” as lung cancers, which they are.

Quit-smoking treatments safe, effective, review says

Popular smoking cessation treatments - such as nicotine replacements and antidepressants - improve people's chances of kicking the habit without much risk, according to a review of past research. “It seems very clear that medications can help. They're not the magic bullet but you do improve your chances of quitting - generally - if you try them. And as far as we can tell, they're safe to use,” said Kate Cahill, who led the study. Several reviews have looked at the effectiveness of smoking cessation treatments, but the researchers wanted to put those results into a single large review to help people who want to use medical treatments to stop smoking, Cahill, a senior researcher for the Cochrane Tobacco Addiction Group at the University of Oxford, UK, said. About one fifth of the U.S. and UK populations are current smokers, according to the researchers. Previous studies have found between 70 percent and 75 percent want to quit, but only about 3 percent accomplish that every year. For the new study, the researchers pulled data from 12 reviews published by the Cochrane Collaboration, an international research organization that evaluates medical evidence. Those analyses, which were conducted between 2008 and 2012, included data from 267 studies of more than 101,000 smokers. The studies typically compared smokers trying to quit without the help of a smoking cessation treatment to smokers using nicotine replacement therapies, such as nicotine gum and patches, or prescription drugs. The medications include varenicline (marketed by Pfizer as Chantix or Champix) and bupropion (marketed by GlaxoSmithKline as Zyban or Wellbutrin, but available as a generic). The researchers found that the nicotine replacement therapies and the antidepressant bupropion led about eighteen people to successfully give up smoking for every 10 people who quit without treatments. Varenicline performed even better and led to about 28 people quitting for every 10 who did so without medication. What's more, Cahill and her colleagues found that lesser-known smoking cessation treatments were also effective. Those include the antidepressant nortriptyline and cytisine, a plant-derived supplement available in Eastern Europe. All of the treatments also appeared to be reasonably safe, according to the researchers who published their results on Thursday in The Cochrane Library. Previous reports have found that about 1 in every 1,000 people taking bupropion has a seizure, but the researchers found a lower rate of 1 in 1,500. Also, despite conflicting reports over the safety of varenicline, the researchers didn't find evidence that the drug increased the risk of neuropsychiatric or heart problems. Judith Prochaska, who researches tobacco treatment but was not involved in the new study, said not all smokers will use smoking cessation tools but it's important for them to know they're available. Nicotine replacement therapy is available over the counter in the U.S. and varenicline and bupropion are available with a prescription for about $4 per day - less than a pack of cigarettes, said Prochaska, associate professor of medicine at the Stanford Prevention Research Center in California. “They have been shown to pretty much double the likelihood that somebody will quit,” she added. Cahill cautioned, however, that smoking cessation tools won't work for everyone, but “they certainly help some people.”source : http://www.foxnews.com/health/2013/05/31/quit-smoking-treatments-safe-effective-review-says/

Most travelers survive in-flight medical emergencies, study shows

Is there a doctor on board? Surprisingly often, there is - in half of in-flight medical emergencies - and sick airline passengers almost always survive, a new study finds. The research is the largest look yet at what happens to people who develop a medical problem on a commercial flight - about 44,000 of the 2.75 billion passengers worldwide each year, researchers estimate. Most cases don't require diverting a plane as the study's leader, Dr. Christian Martin-Gill, advised a pilot to do two years. He works for MD-STAT, a service at the University of Pittsburgh Medical Center that advises about 20 major airlines on how to handle in-flight emergencies. Another large service is based in Phoenix. Martin-Gill handled a call when a passenger seemed to be having a heart attack on a flight from Europe to the U.S. The man's implanted defibrillator had shocked his heart five times to try to restore normal rhythm. “The aircraft was in the middle of its destination, flying over the Atlantic,” so he recommended landing at Newfoundland off the Canadian coast to get the man to the nearest hospital, Martin-Gill said. The federally funded study reviewed about 12,000 cases handled by the Pittsburgh center over nearly three years. Results are in Thursday's New England Journal of Medicine. Researchers found: -The odds of a medical emergency are 1 per 604 flights, or 16 per 1 million passengers. -Planes had to be diverted for emergency help in only 7 percent of cases. -Doctors were on board and volunteered to help in 48 percent of cases; nurses and other health workers were available in another 28 percent. Only one-third of cases had to be handled by flight attendants alone. -The most common problems: Dizziness or passing out (37 percent of cases); trouble breathing (12 percent) and nausea or vomiting (10 percent). -About one-fourth of passengers were evaluated at a hospital after landing and 9 percent were admitted, usually with stroke, respiratory or cardiac symptoms. -Out of nearly 12,000 cases, a defibrillator was applied 137 times, including in 24 cases of cardiac arrest, where the heart had stopped. (Sometimes defibrillators are used to analyze an irregular heart rhythm to help doctors figure out what to do, not necessarily to deliver a shock.) -Of the cases in this study, only 36 deaths occurred, 30 of them during the flight and the others after landing. -Pregnancy-related problems were generally rare - 61 cases, in this study - and two-thirds of them involved women less than 24 weeks along with possible miscarriages. Air travel is considered safe up to the 36th week, or the last month, of pregnancy. Only three cases of women in labor beyond 24 weeks of pregnancy led to a plane being diverted. Dr. Lisa Rosenbaum, a University of Pennsylvania cardiologist, helped in a case like that in 2007, on a flight from Boston to Portland, Ore. The passenger was three months from her due date but was having contractions every minute - something that can often be stopped with drugs and treatment at a hospital but not in midair. “It was clear to me that labor was imminent and that we needed to land the plane,” so, on her advice, the pilot diverted to upstate New York, Rosenbaum said. “It was one of the scariest experiences of my life. It's not like taking care of a patient in the hospital.” Dr. David Rogers, a pediatric surgeon at the University of Alabama at Birmingham School of Medicine, felt that fear five years ago when an elderly woman had trouble breathing during a flight to Atlanta from Toledo, Ohio. Being a specialist at treating children rather than adults, “my first reaction was to look around and hope there would be somebody else” more qualified to help, he said. Luckily, a flight attendant had already given the woman an oxygen mask and she seemed to be improving, so he felt the plane could continue to Atlanta, the woman's home. Trying to determine whether to divert a plane was a tough call, he said. “I'm making a decision that's going to affect a plane full of people,” not just the patient, Rogers said. Some passengers may fear liability if they help in such situations, but a Good Samaritan law protects those who do so, the study notes. And although health workers are not legally obliged to help, they have a moral obligation to do so, the authors write. And you never know what kind of help will be requested. Martin-Gill said a partner once was consulted when a dog suffered a cardiac arrest during a flight. He didn't know how things turned out.source : http://www.foxnews.com/health/2013/05/30/most-travelers-survive-in-flight-medical-emergencies-study-shows/

Pork industry hunts for deadly pig virus

The sudden and widespread appearance of a swine virus deadly to young pigs - one never before seen in North America - is raising questions about the bio-security shield designed to protect the U.S. food supply. The swine-only virus, the Porcine Epidemic Diarrhea Virus (PEDV), poses no danger to humans or other animals, and the meat from infected pigs is safe for people to eat. Though previously seen in parts of Asia and Europe, the virus now has spread into five leading hog-raising U.S. states. How it arrived in the United States remains a mystery. While the U.S. imports millions of pigs each year from Canada, it imports pigs from virtually no other country, and no Canadian cases of PEDV have been confirmed. Veterinarians and epidemiologists say pigs are infected through oral means, and that the virus is not airborne and does it not occur spontaneously in nature. In recent years, with the emergence of dangerous pathogens such as H1N1, also known as swine flu, and bovine spongiform encephalopathy (BSE) or mad cow disease, the United States and other countries have sought to secure defenses both on the farm and at the national borders to protect against barnyard epidemics. “We're just trying to get a handle on what's happening,” said Tom Burkgren, executive director of the American Association of Swine Veterinarians. “It's like drinking water out of a fire hose. We're getting hits from all over the place.” Overall numbers of confirmed cases and mortality rates are not yet available, though anecdotal evidence suggests there are devastating losses for farms that are hit. “If you've got it, it's bad,” said Mark Greenwood, vice president of agri-business capital at AgStar Financial Services, who said none of his clients have been affected. “I spoke to a farmer in the Midwest who had it show up in a 2,000-head barn of pigs, and had a 40 percent death loss.” A spokeswoman for U.S. Department of Agriculture's Animal and Plant Health Inspection Service told Reuters the agency is working with state agencies and pork industry officials to discover where the virus originated. THE VIRUS SPREADS Confirmed cases have been reported in five hog-raising states including Iowa, the largest U.S. hog producer with 20 million hogs, according to the USDA. While only seven farms have had confirmed cases since May 17, more cases are expected as labs sift through samples, say sources investigating the outbreak. Colorado, Indiana, Illinois and Minnesota reportedly have positive tests for PEDV, according to state veterinarians and agriculture department officials, and the National Veterinary Services Laboratory in Ames, Iowa. PEDV, most often fatal to very young pigs, causes diarrhea, vomiting and dehydration. It also sickens older hogs, though their survival rate tends to be high. Known as a “coronavirus” because of the crown-like spikes on its surface, the virus afflicted China in recent years and killed more than 1 million piglets. PEDV is spread most commonly by pigs ingesting contaminated feces. Investigators are focused on physical transmission, perhaps a PEDV infected pig, equipment marred with feces, or even a person wearing dirty boots or with dirty nails. The mystery about how the virus entered the United States is raising concern about potential holes in the bio-security shield designed to protect the U.S. food and farming sectors. “Like everything else, we screw up from time to time,” said Ronald L. Plain, professor of agricultural economics at University of Missouri in Columbia, Missouri. “We know so little about the transmittal of this virus. We can't be sure if it's happening because of something we're supposed to do right and didn't - or by some mechanism we don't know that we're supposed to do differently.” Initial reporting about the virus may have been delayed, say sources, because its symptoms can be confused with a more common malady, transmissible gastroenteritis (TGE). Also, states are not required to report cases of PEDV to the federal government, and farmers are not required to report to state veterinarians. As part of its assessment of the situation, USDA will email epidemiological surveys to swine veterinarians who are dealing cases of PEDV. Meanwhile, the veterinarians are sending samples to diagnostic labs, where technicians are scrambling gathering the tools needed to check the samples for PEDV - supplies many labs did not have prior to the outbreak. While most farmers are taking a wait-and-see approach, some told Reuters they are turning away unnecessary visitors and double checking to ensure their safety protocols are being followed. LOOKING NORTH The search for leads also has turned to the nation's borders and ports of entry - specifically, Canada, where the United States imported 5.7 million head of live hogs last year. Canada has never had a confirmed case of the virus, though it does not test for it, government officials said. “Canada has very effective import measures in place to address this risk,” said Dr. Rajiv Arora, senior staff veterinarian for the Canadian Food Inspection Agency's foreign animal disease section. Canada can import live breeding pigs, under permits, from either the United States or the European Union, Arora said. The animals are quarantined by CFIA for a period of time, then inspected and tested - although not for PEDV - before released. Canada imported C$1.7 million ($1.6 million) worth of live swine in 2012, including both slaughter-ready and breeder pigs, according to Canada's Agriculture Department. CHINA HARD HIT Veterinarians and agricultural epidemiologists in the United States are drawing grim lessons from the devastating effect PEDV has had in other countries where it has hit. The first reports of suspected PEDV came in 1971 in the United Kingdom. As years passed, PEDV spread across parts of Europe and Asia. Veterinary researchers later concluded that lax bio-security measures contributed to PEDV's spread in Asia. One of the worst known outbreaks of the virus hit China's pig herds in late 2010, according to the Centers for Disease Control and Prevention's Emerging Infectious Diseases Journal. Vaccines had limited effectiveness and PEDV over ran southern China killing more than 1 million piglets. The death rate for virus-infected piglets ranged from 80 percent to 100 percent. Biosecurity measures in the U.S. food supply have been beefed up over the years, and especially after the outbreaks of mad cow disease and swine flu. Both outbreaks posed risks to human health. Today, trucks carrying live animals are supposed to be cleaned before entering and leaving farms. At commercial hog operations, visitors routinely shower and change clothing before stepping into a barn. Overseas visitors typically wait several days before being in the presence of a commercially raised hog. But the food shield is not impermeable. “If it becomes clear that this is not a novel way for to be transmitted, and that there had to be physical contact, that's going to be a major concern,” said William Marler, a leading food-safety attorney. “It means that there was a failure in the system.”source : http://www.foxnews.com/health/2013/05/29/pork-industry-hunts-for-deadly-pig-virus/

Chaga: A potent immune enhancing fungus

Recently my wife and I were walking in the woods when I spotted a rotting birch tree. All over the decaying trunk were clusters of a gnarly black growth, which I quickly recognized as chaga (Inonotus obliquus). &#160;Relatively unused in the west, chaga is a potent immune enhancing agent that is highly popular in Russia and parts of Europe, and it enjoys a major body of science for its health benefits. Unlike most fungus, chaga is hard and woody, bearing no resemblance to mushrooms. Instead, it looks more like a cracked piece of burned charcoal. Chaga’s black color is due to a concentration of melanin, the same pigment that colors human skin. Because chaga can be used to start fires, it is also known as the “tinder fungus.” The name chaga derives from the Komi-Permyak language of Russia’s Kama River Basin, where the fungus has played a role in traditional medicine for centuries. Chaga can be found throughout northern Asia and in Canada, Norway, northern and eastern Europe and northern parts of the United Sates. Chaga is rich in natural antioxidant and anti-inflammatory phenols, containing the compounds betulin and betulinic acid – which derive directly from host birch trees. Both betulin and betulinic acid demonstrate anti-tumor effects, which explain why chaga is known as an anti-cancer agent. Additionally, some science shows that betulin can play a beneficial role in controlling metabolic disorders, such as obesity and metabolic syndrome. A group of compounds in chaga called lanostanoids also appear to play significant anti-cancer roles. The exact anti-cancer activity of chaga is not completely understood, but some compounds in the fungus boost immune activity, some specifically prevent cancer cells from replicating, and others cause premature cancer cell death. This argues for the utilization of a whole chaga extract, rather than isolating a single compound. In chaga, many agents appear to be active against cancer. One of the most surprising benefits of chaga is in regards to psoriasis. In one Russian study, psoriasis patients who took chaga recovered from their condition. Given that psoriasis is notoriously difficult to treat and responds to very little therpaies, this effect alone could be of enormous benefit to many. The compound ergosterol in chaga, along with related agents, shows anti-inflammatory activity. This may account for why chaga is thought of as a life-extending agent in China, as inflammation is part of every chronic, degenerative disease. Reducing systemic inflammation can mitigate or help prevent a variety of health problems, leading to a healthier life – and presumably a longer one. Traditionally, chaga has been used for a variety of purposes. Scientific investigation chaga’s use as an anti-allergy agent shows that in animals, the fungus has the ability to prevent anaphylactic shock – a serious and potentially fatal consequence of a severe allergy. In another study, administration of an extract of chaga reduced infection due to the Herpes simplex virus. In a cell study, chaga showed potent activity against the hepatitis C virus. Whether this same activity will prove true in living humans remains to be seen, but if it does, then chaga will benefit thousands of people who often suffer for many years with this crippling disease. Chaga products are widely available in natural food stores and on the Internet. One chaga product I like is made in Vermont and is available at www.Mariefrohlich.com. Considering that spring is here and chaga demonstrates value against allergies, this may be an excellent time to try chaga, whose nickname “Mushroom of Immortality” appears to be far more than just a clever slogan.Chris Kilham is a medicine hunter who researches natural remedies all over the world, from the Amazon to Siberia.

Small cancer risk following CT scans in childhood and adolescence confirmed

CT (computed tomography) scans have great medical benefits, but their increasing use since the 1980s has raised some concerns about possible cancer risks, particularly following exposures in childhood. Most previous studies have estimated risks indirectly, and some radiation experts have questioned the validity of these estimates. There is currently much uncertainty and as such, researchers from Australia and Europe carried out a study comparing cancer rates in patients exposed to CT scans at ages 0-19 years compared with unexposed persons of a similar age. All participants were born between 1985 and 2005 with total follow-up ending at the end of 2007. …

Babies who share bed with parents 5 times more likely to die of SIDS

Babies sharing beds with their parents face a five-fold risk of dying of cot death, even if their parents are not smokers, new research shows. The increased risk of death extends to babies previously thought to be at low risk because they are breastfed and the mother has not taken alcohol or drugs, according to a study published in the British Medical Journal Open. The findings come after 1472 Sudden Infant Death Syndrome (SIDS) cases and 4679 control cases from Australasia, the U.K. and Europe were analyzed in the largest ever study of cot death. The SIDS rate would plummet if parents avoided bed sharing and public healthy messages were more forceful about the dangers for babies under three months, the authors, led by Professor Robert Carpenter, said. “Eighty-eight percent of the deaths that occurred while bed sharing would probably not have occurred had the baby been placed on its back in a cot by the parents' bed,’’ the authors concluded. The risk of SIDs while bed sharing decreased as the baby gets older. Bed sharing has increased “markedly’’ over the last decade, the study found. Parents who endorse the practice are active on the Internet and Facebook. Murdoch University associate professor Catherine Fetherson said research shows between 30 and 50 percent of parents share a bed with their babies at some time. She believes a blanket message against bed sharing is driving parents underground. “They are continuing to do it, even though people are being warned against it and so what is happening is they are shutting down all communication with health professionals,’’ she said.
