Smokers 'need more help to quit' 2007-10-04 23:38:00 news.bbc.co.ukNicotine should be freely available in products which do not carry cigarettes' health risks, to help smokers who find it impossible to quit, say doctors. Nicotine should be freely available in products which do not carry cigarettes' health risks, to help smokers who find it impossible to quit, say doctors. Millions continue to smoke because they are addicted to nicotine, but it is the toxins in cigarette smoke that kill, said the Royal College of Physicians. It called for the regulation of new cigarette substitute products to give the "nicotine hit" that smokers crave. The Department of Health said it would consider the RCP report. The RCP said its proposals could help to prevent millions of deaths and would particularly help the worst off, who tend to smoke more heavily and find it harder to stop. 'Safe sources' Professor John Britton, report author and chairman of the RCP tobacco advisory group, said: "Smokers

Body's Own Stem Cells Could Trigger Cancer Spread 2007-10-04 05:32:00 www.medicalnewstoday.comWritten by: Christian NordqvistYour body's own stem cells could trigger alterations in cancer cells which facilitate their spreading around the body, say scientist from the Whitehead Institute, USA. They found that human breast cancer in mice have a higher chance of spreading if they are blended with bone marrow stem cells. Fortunately, say the scientists, it is perhaps feasible to reverse the process, undermining the deadliness of the cancer. You can read about this study in the journal Nature.When metastasis occurs it is much harder to treat the cancer. Metastasis is when the cancer invades other parts of the body and forms new tumors. In this study, the scientists intended to find out whether it was possible to stop this from happening - they wanted to find a means of isolating the cancer to one part of the body; stopping it from metastasizing (spreading, invading other parts). The researchers have found an association with a specific type of stem cell, whic Read more:Cancer

Scientists Advise Pregnant Women to Eat Fish 2007-10-04 04:08:00 www.sun-sentinel.comBy Sally SquiresIn a major break with current U.S. health advice, a coalition of top scientists from private groups and federal agencies plans to advise pregnant and breast-feeding women to consume at least 12 ounces of fish and seafood per week to ensure optimal brain development of their babies.That recommendation, which will be announced at a news conference today, essentially is at odds with the standard government advice since 2001 that these groups should eat no more than 12 ounces of seafood a week because of concerns about mercury contamination.The new advisory comes from the National Healthy Mothers, Healthy Babies Coalition, a nonprofit group with nearly 150 members, including the American Academy of Pediatrics, the March of Dimes, the National Institute on Child Health and Human Development, and the Centers for Disease Control and Prevention.Concerns over the impact of fish on the brain development of fetuses and infants, the most vulnerable groups, have Read more:Women
7 ways to fight breast cancer 2007-10-04 01:44:00 detnews.comCarolyn Clifford Since October is Breast Cancer Awareness Month, it is likely that we all will be hearing tips on preventing and treating breast cancer. Since some of the diet data is contradictory, you may not want to change your eating habits based on one study. But here are seven pieces of advice from the American Cancer Society you may want to consider.Limit alcohol consumption. The research shows alcohol increases the risk of several kinds of cancer, including breast cancer. People who drink alcohol should limit consumption to no more than two drinks a day for men and one drink a day for women. Women at high risk of breast cancer may want to cut out alcohol altogether.Eat more antioxidants. Antioxidant nutrients include vitamin C, vitamin E, carotenoids and many other chemicals from plants. Studies show that people who eat more veggies and fruits may have a lower risk for some types of cancer.Don't worry about coffee. While caffeine may heighten symptoms of fibrocystic Read more:fight
Five Myths About Breast Cancer and Why You Shouldn't Believe Them 2007-10-04 01:17:00 www.foxnews.comWe’ve all heard the wives’ tales. Deodorant will give you breast cancer and so do microwaves and tight-fitting bras.Alas, all of these tales are fictitious. And, unfortunately, there are a lot of other seemingly believable myths on breast cancer floating around, say doctors.Many women, for example, have been told that women under the age of 40 should be getting mammograms and it’s the greedy insurance industry that is preventing them from doing so.Mammograms, however, are ineffective for most young women, which is the real reason why they are discouraged from getting them, said Dr. Diana Zuckerman, president of the National Research Center for Women & Families.“Young women’s breasts are dense and if they get mammograms, their breasts show up very white on mammograms and cancer shows up as white,” she said. “But, as women get older, their breasts are less dense and show up gray on a mammogram, which makes it easy to identify the white cancer.

Panic Attacks May Increase Heart Risk 2007-10-03 07:29:00 www.cbsnews.comBy Salynn BoylesMore Heart
Attacks Seen In Older Women Who Experience Panic
AttacksOlder women who experience panic attacks appear to have an increased risk for having heart attacks or heart-related death, new research suggests.Postmenopausal women in the study who reported at least one full-blown panic attack within six months of being interviewed were four times as likely as other older women to have a heart attack or related death over the next five years.They were three times as likely to have either a heart attack, heart-related death, or stroke, and nearly twice as likely to die from any cause.Earlier studies have implicated depression as a risk factor for heart disease, but the new research is the first to suggest a direct link between anxiety-related panic attacks and heart attack and stroke risk.Harvard Medical School associate professor of psychiatry Jordan W. Smoller, M.D., who led the study team, says more research is needed to confirm the finding."There is n
Weight Loss Can Normalize Blood Pressure 2007-10-02 05:03:00 www.medpagetoday.comBy Charles BankheadAt least half of overweight patients with stage I hypertension can normalize their blood pressure with modest weight loss, Italian investigators reported here. After six months on a reduced-calorie diet, supplemented by a lipase inhibitor in some cases, about half of 210 patients lost more than 5% of their body weight, which was associated with about a 5% reduction in blood pressure, Roberto Fogari, M.D., of the University of Pavia, reported at a conference of the American Heart Association's Council for High BloodPressure
Research. The results demonstrated not only that weight loss alone can normalize hypertension but also that many overweight hypertensive patients have been misdiagnosed as having essential hypertension. The results emphasize the importance of initiating dietary intervention in overweight patients with high blood pressure before resorting to drug treatment, said Dr. Fogari.

Contraception: Progress Brings Hope For New Methods For Men 2007-10-01 04:46:00 www.sciencedaily.comBut will men actually use a new method if researchers make one? Elaine Lissner, director of the nonprofit Male Contraception Information Project, says demand is the least of the problems. "You'll never have all men interested, but attitudes have really changed - studies consistently show a majority of men would consider it. You have to remember, between condoms and vasectomy, men in the U.S. are already taking care of a third of contraception.

Arizona Teenager Killed by Brain Eating Amoeba 2007-09-30 23:43:00 http://www.shortnews.com/Aaron Evans, 14, was the sixth victim to die from Naegleria fowleri infection. The amoeba, which likes warm shallow waters, enters the brain through the nasal cavity. Once infected, victims invariably succumb. There is no effective treatment.Evans is believed to have been infected while swimming at Lake Havasu. Usually found in the southern US, the CDC said Naegleria can be in any lakes, hot springs or swimming pools, and warns people to stay away from warm sandy water.Michael Beach, a CDC specialist, believes that rising temperatures in upcoming decades will bring more Naegleria attacks.Lake amoeba can kill swimmers Read more:Arizona

Health care for children is a good investment 2007-09-30 12:46:00 www.bradenton.comInvesting in affordable health care coverage for our nation's low-income children saves taxpayer dollars in the long run - and it's the right thing to do. Nothing is more important than the health of our children. Yet many of the estimated 47 million Americans who go without health insurance every day are children. These kids will either forego health care, which could lead to costly chronic conditions, or land in the emergency room at taxpayer expense.In 1997, Congress approved by an overwhelming and bipartisan margin the creation of the children's health insurance program to extend health care to 6 million kids across the country. The results have been a resounding success. Since its creation, the program has reduced the number of uninsured kids in America by one-third. Nearly all of those children live in families with income levels not much higher than the federal poverty level, or about $41,000 for a family of four.Currently 6.6 million low-income kids national Read more:Health

Tobacco Age Of Sale Rises To 18 On Monday, UK 2007-09-30 12:31:00 http://www.medicalnewstoday.com/.Photo by http://www.stanfordreview.org/From Monday
1st October the tobacco age of sale will increase from 16 to 18 in the latest government step to cut smoking rates in the UK, and prevent young people buying tobacco. This major step follows on from public places going smokefree in July and the recent announcement by the Secretary of State that cigarette packets will carry picture health warnings from next year. An outdoor advertising campaign to explain the the change in the law was launched on Monday 24th September as part of an awareness campaign over the past four months to ensure that both retailers and teenagers are fully aware. Public Health Minister Dawn Primarolo said: "We are determined to reduce the number of young people who smoke. Raising the legal age of sale to 18 will make it easier for retailers to spot under-age smokers and lead to less young people becoming addicted to nicotine and continuing to smoke into adulthood.

Is Hillary’s health care plan good for America? 2007-09-28 04:45:00 www.dailyamerican.comBy JOE BETTAAn April 27, 2004, Capitalism Magazine article, ‘Watchout for Hillary
Health Care’ by Thomas Sowell says that Hillary’s legitimate reasons for government universal healthcare are “soaring health costs and millions of uninsured,’ and the government can do it better and cheaper. She also believes that our mental health systems are underfunded.I listened to presidential candidate Hillary Clinton’s health care plan for everybody for free on national TV. She said that her plan had a $110 billion annual budget; but not to worry taxpayers, the business community will get tax credits or the option of joining her new federal insurance system that will cover all of their employees. Hillary said that unlike her ‘93 one-size fits all solution, the people have choices this time.Joe Klein also analyzed her new approach to universal healthcare in a Sept. 20 ‘What Hillary has learned from ’93’ article in “Time” archives.

For Some, Diabetes Care Worse Than Illness Itself 2007-09-28 02:01:00 Complicated daily regimens lower their quality of life, survey finds For some people with diabetes, the burden of adhering to their daily care regimen nearly equals that of their diabetes-related health complications, a U.S. study finds.University of Chicago researchers conducted interviews with more than 700 adults with type 2 diabetes.As reported in the October issue of Diabetes
Care, some patients said the inconvenience and discomfort of having to take numerous medications each day, carefully monitoring their diet, and getting the required amounts of exercise had a major impact on their quality of life.Each day, a typical diabetes patient takes many medications, including two or three different pills to control blood sugar levels, one or two pills to lower cholesterol, two or more pills to reduce blood pressure, and an aspirin to prevent blood clots. As the disease progresses, the number of drugs increases and often includes insulin shots, according to background information in the Read more:Itself
Omega 3 fatty acid reduces type 1 diabetes 2007-09-27 02:30:00 U.S. researchers say dietary omega-3 fatty acids may reduce the risk of developing diabetes in children who are genetically at risk for the disease.The study, published in the Journal of the American Medical Association, found higher consumption of omega-3 fatty acids - found in fish - by children at risk for type 1 diabetes decreased by 55 percent the risk of pancreatic islet autoimmunity, which is linked to development of diabetes.Although it is not yet known what initiates the autoimmune process in diseases such as type 1 diabetes, the study authors believe it is likely that both genetic background and environmental factors such as dietary factors contribute to the disease process. Jill M. Norris of the University of Colorado at Denver led researchers in examining the diets of 1,770 children at increased risk for type 1 diabetes - defined as having either a high diabetes risk human leukocyte antigen genotype or a sibling or parent with type 1 diabetes.

Man's voice an indicator of sexual potency: study 2007-09-26 06:34:00 Canadian Research; Men with deep tones produce more childrenTom BlackwellFor many women, the deepness of a man's voice is one of the most powerful aphrodisiacs, a new study co-authored by a Canadian psychologist suggests.All else being equal, males with lower voices produce more children than their higher-pitched counterparts, concluded the researchers in a search for evolutionary explanations of sexual attraction.The study looked at Tanzania's Hadza tribesmen, one of the world's few remaining hunter-gatherer societies, because the Hadzas never use birth control, a complicating factor that makes it impossible to do such research elsewhere in the world.The discovery that the pitch of their voices was a major determinant of how many children they would father underlines the deep-seated roots of the seemingly superficial human trait, said David Feinberg, a psychology professor at Mc-Master University in Hamilton, Ont.Previous research has indicated that a deep voice signifies robust g
Childhood Obesity - Eating Habits in Children influenced by Easily Accessible Unhealthy Choices 2007-09-26 05:39:00 www.bestsyndication.comBy Mark BaroneA group of studies were reported in this week’s supplemental issue of the American Journal of Preventative Medicine. The journal compiled a number of studies that showed the different pressures that cause children and teenagers eat the wrong foods, and may be the reason for obesity epidemic.Researchers from the University of Michigan found that there were several factors that influence children into eating unhealthy food choices. One discovery is that most middle and high schools across the United States have contracts with the soft drink industry. The study reports 67 percent of the middle schools and 83 percent of the high schools will have soft drinks available for children to purchase. These kids have easy access to sugary drinks when they attend school. Why would the schools allow this? They do this for the extra income. The schools earn on average $6,000 per year or $6.48 per student at the high school level and $500 per year on average or Read more:Children

Sex Boost From Late Hormone Therapy 2007-09-25 07:25:00 www.webmd.comBut No Memory Benefit From Hormone Therapy
Years After MenopauseBy Daniel J. DeNoonHormone therapy begun years after menopause doesn't improve mental function, but it does boost sexual interest, researchers find.Forgetfulness is more of a problem for women during and after menopause than it is before menopause. Does this mean the hormonal changes of menopause cause a decline in mental function? And if so, can hormone therapy help?Studies suggest that hormone therapy begun during menopause can preserve mental function. Might later hormone therapy do the same?In a study funded by Wyeth, the maker of the hormone products Prempro (estrogen plus progesterone) and Premarin (estrogen only), 180 healthy women began taking either Prempro or inactive placebo pills one to three years after menopause.After four months of treatment, researchers Pauline Maki, PhD, of the University of Illinois at Chicago and colleagues gave the women a battery of mental-function tests.

Lack of sleep, too much sleep, both deadly 2007-09-25 00:43:00 www.upi.comA lack of sleep can double the risk of death from cardiovascular disease, but too much sleep can also double the risk of death, British researchers found.Researchers from the University of Warwick, and University College London have found those who had cut their sleeping from 7 hours to 5 hours a night or less faced a 1.7 fold increased risk in mortality from all causes, and twice the increased risk of death from a cardiovascular problem in particular.They also found that those, who increased their sleep from 8 hours or more a night, were more than twice as likely to die predominantly from non-cardiovascular diseases.Francesco Cappuccio of the University of Warwick’s Warwick Medical School studied how sleep patterns affected the mortality of 10,308 civil servants in the Whitehall II study at two points in their life during 1985 to 1988 and those still alive in 1992 to 1993.

Europe gives final approval to Pfizer HIV drug 2007-09-24 04:55:00 economictimes.indiatimes.comLONDON: Pfizer
Inc, the world's largest drugmaker, said on Monday the Europe
an Commission had approved its AIDS drug Celsentri, the first in a new class of oral HIV medicines.The drug, which is known generically as maraviroc and as Selzentry in the US, is the first designed to keep the HIV virus that causes AIDS from entering healthy immune cells. Older AIDS medicines attack the virus itself.It works by blocking the CCR5 co-receptor that serves as a main doorway for the HIV virus into immune cells.The green light from the European authorities had been expected after a panel of EU experts recommended the product in July. The medicine was also cleared by the US Food and Drug Administration last month.Celsentri is approved for use in patients who have tried other medicines and for whom a diagnostic test has confirmed their HIV strain is linked to the CCR5 receptor.New York-based Pfizer is counting on new medicines such as Celsentri to help drive profits as sev
New test to detect bird flu 4 times faster 2007-09-24 01:38:00 www.todayonline.comTan Hui LengANOTHER made-in-Singapore bird flu detection device has been announced: Claimed as able to identify the deadly H5N1 strain in less than 30 minutes, or 440 per cent faster than other commercially available tests. The device, conceived at the Institute of Bioengineering and Nanotechnology (IBN) at the Agency for Science, Technology and Research, can be used together with commercially available H5N1 kits."There is a difference between 'kits' and 'devices'," said research scientist Juergen Pipper, who headed the project. The invention was announced in the journal Nature Medicine."Kits contain biochemicals only (while) devices are hardware only. That means, kits alone are not enough; they have to be combined with devices to test for infectious diseases."IBN's device works by testing genetic material obtained from a throat-swab of humans, and is described as a "lab-on-a-chip". Dr Pipper also said the device would be between "2,000 to 5,000 per cent cheaper
Reduce Calories And Live Longer 2007-09-23 10:22:00 www.dbtechno.comFor decades we we have known that reducing calorie intake — not nutrients — can be beneficial and increase life expectancy, but we didn’t know why, until now.According to U.S. researchers, the benefits of calorie reduction can be seen at a molecular level.In a study released Thursday, scientists suggest that the link between calorie restriction and longevity may be a molecular response to stresses from reducing calorie intake.Researchers believe that the reaction preserves critical cellular functions between enzymes created by two genes called SIRT3 and SIRT4,. The reaction increases the bodies ability to fight age related disease, reported CNN.“We’re not sure yet what particular mechanism is activated by these increased levels of NAD, and as a result SIRT3 and SIRT4,” said David Sinclair, a molecular biologist at Harvard Medical School who worked on the study.“These two genes, SIRT3 and SIRT4, they make proteins that go into mitochondria. … These are l Read more:Calories
Surviving Colorectal Cancer 2007-09-21 04:53:00 www.ivanhoe.comA new study uncovers the best treatments to prolong survival for patients with advanced colorectal cancer, but researchers have a warning about their toxic effects.Researchers from the University of Ioannina School of Medicine in Greece conducted a meta-analysis of 242 randomized trials to compare treatment regimens for patients with advanced colorectal cancer. The studies were pulled from the last 40 years to determine whether certain treatments were better at stabilizing the disease and prolonging survival than others.Researchers report, for patients expected to live one year on a treatment of fluorouracil (Adrucil) and leucovorin, there was an absolute survival benefit of eight months when an additional treatment of irinotecan (Camptosar) plus bevacizumab (Avastin) was added. There was also a survival benefit noted after adding oxaliplatin (Eloxatin) plus bevacizumab or irinotecan plus oxaliplatin, though the success was less with a 4.7-month additional survival bene Read more:Cancer

1 in 3 Americans uninsured 2007-09-21 04:43:00 www.recordnet.comSituation worse in California, study concludesBy Joe GoldeenIf 43-year-old Donald Howlin could sleep through the night, chances are his dreams wouldn't be sweet. They'd be nightmares, much like the living nightmare he's going through trying to obtain adequate health care.The situation for Howlin, a Lathrop father of five who lives with a broken body and chronic pain, is one of millions of complex stories of formerly working Americans
with debilitating injuries or illnesses who find themselves dependent on a strained health-care system."I don't understand the system anymore," Howlin said Thursday. A new report shows Howlin is not alone.Approximately 89.6 million Americans - including 13 million Californians - were uninsured at some point in 2006-07, according to a report released Thursday by the health consumer organization Families USA.Nationwide, that's more than one in three people, or 34.7 percent younger than 65, when federally sponsored Medicare kicks in.In C
Using testicles to fix the brain, heart and blood 2007-09-20 06:35:00 www.theglobeandmail.comLife-saving remedies viewed as possible ANNE MCILROYMen have a source of potentially life-saving stem cells between their legs.A team of American researchers has found a way to easily identify stem cells in the testicles of adult mice that can be coaxed to turn into brain cells, muscle cells, heart cells, blood cells and even blood vessels. One day, they say, male patients may be able to turn to their own testicles as a source of stem cells to repair an ailing heart or kidney or to fix the brain damage caused by Alzheimer's or Parkinson's disease.The procedure would involve removing a small piece of testicle - about the same amount used for a biopsy."We don't need a lot of material," says Marco Seandel, the lead author of a paper to be published today in the journal Nature and a stem cell researcher at the Howard Hughes Medical Institute in Maryland.His team's work - and that of a German team also experimenting with stem cells extracted from testicles - is pa
Take a siesta to reduce your blood pressure 2007-10-16 05:57:00 www.dailyindia.comA new study has found that expecting an afternoon nap could reduce
blood pressure, consequently cutting down the risk of heart attacks.Researchers at the Liverpool John Moores University in Liverpool, U.K., have discovered that the time just before one falls asleep in the afternoon is the most beneficial in reducing blood pressure and lessening the risk of cardiovascular diseases.Afternoon naps, or siesta
s are typically short naps or rest periods of no more than an hour that are taken in the afternoon.While earlier studies on siestas have found that this practice may slightly increase the risk of heart attack, the new study has shown an inverse relationship between siesta taking and fatal heart attacks. According to the researchers, change in blood pressure is the key factor linking afternoon naps to cardiovascular function. Some researchers hypothesize that the lower blood pressure reduces strain on the heart and decreases the risk of a fatal heart attack.The current
Sex Every Day is Prescription for Improving Sperm Quality 2007-10-16 02:21:00 www.timesonline.co.ukMen who suffer fertility problems because of low sperm quality may be able to improve their chances of fatherhood by having sex every day, research has suggested. While those trying for a baby are often told to refrain from ejaculating too often to protect their sperm count, Australian scientists have shown that this can be counterproductive and may lower male fertility. Among men whose fertility problems stem from genetic damage to their sperm rather than a low sperm count, abstaining from sex can make their difficulties worse, research led by David Greening, of Sydney IVF, has shown. The pilot study of 42 men whose sperm showed significant DNA damage found that daily ejaculation reduced this by 12 per cent. While the results are preliminary and no direct effect on fertility has yet been measured, they suggest that certain men could benefit from having sex more often, or from abstaining less before providing semen for use in IVF.

Is dieting or exercise better for weight loss? 2007-10-16 00:04:00 www.boston.comJUDY FOREMANIt's a bit complicated, but basically, it's the net calorie deficit - expending more energy than you consume - that counts, said Eric Ravussin, a physiologist at the Pennington Biomedical Research Center in Baton Rouge, La.In a small, randomized, controlled clinical trial, Ravussin divided three dozen overweight but healthy men and women into three groups. One group reduced their calorie intake by 25 percent. Another group cut calories by half as much (12.5 percent) while increasing energy output through exercise by 12.5 percent; and the third group made no diet or exercise changes.The researchers looked at weight loss, body composition, and measures of superficial and deep fat. They found that it doesn't matter whether people lose weight by diet or by exercise or a combination, although exercise has the important benefit of improving cardiovascular health."So long as the energy deficit is the same, body weight, fat mass, and abdominal fat will all decrease Read more:better
Why garlic is good for the heart 2007-10-15 23:47:00 news.bbc.co.ukResearchers have cracked the mystery of why eating garlic can help keep the heart healthy.The key is allicin, which is broken down into the foul-smelling sulphur compounds which taint breath. These compounds react with red blood cells and produce hydrogen sulphide which relaxes the blood vessels, and keeps blood flowing easily.The University of Alabama at Birmingham research appears in Proceedings of the National Academy of Sciences. However, UK experts warned taking garlic supplements could lead to side effects. Hydrogen sulphide generates a smell of rotten eggs and is used to make stink bombs. But at low concentrations it plays a vital role in helping cells to communicate with each other. And within the blood vessels it stimulates the cells that form the lining to relax, causing the vessels to dilate. This, in turn, reduces blood pressure, allowing the blood to carry more oxygen to essential organs, and reducing pressure on the heart. The Alabama team bathed rat blood v
Obesity linked to elevated risk of esophageal cancer 2007-10-12 02:03:00 FoodConsumer.orgBy David LiuObese people are more likely to develop cancer of the gullet than those with a normal body weight, a new study finds. But the finding does not mean that obesity is the cause of the disease. The study published in the British journal Gut looked at 793 people with esophageal cancer and 1,580 controls matched for age and residence location. The study found people with a body mass index of 40 or higher were six times more at risk than those with a BMI between 18.5 and 25, which is normal by definition. Those with obesity and acid reflux were 16 times more likely to have the disease. The association was still significant even after other factor such as smoking and alcohol consumption were taken into account. In obese people, high levels of insulin boost production of insulin-like growth factor which is known to stimulate cell growth and inhibits apoptosis, programmed deaths of cells. Both may increase the cancer risk. But further research is needed to confirm the Read more:linked
