Tuesday, Sep 1st, 2009 ↓Breast Cancer: Risk Increases For Smokers And Overweight Women →
Sept 1, 2009 (Sciencedaily.com)—A recent study published in the Journal of Cancer Epidemiology has reinforced the correlation between being overweight, smoking and breast cancer. What makes this study unique is how test subjects were not diagnosed for BRCA1 and BRCA2 gene mutations, which predispose women to breast cancer.
Instead, women with such gene mutations were excluded to allow researchers to concentrate on lifestyle factors such as smoking, exercise, nutrition and weight. All women analyzed in the study were direct ancestors of the first French colonists.
“To our knowledge, this is the first study conducted on a sample of women without BRCA1 and BRCA2 gene mutations, which are often found in French-Canadian women,” says lead researcher Vishnee Bissonauth, a graduate of the Université de Montréal’s Department of Nutrition and a researcher at the Sainte-Justine University Hospital Research Center.

Tobacco Smoking May Increase Risk for Tuberculosis →
September 1, 2009 (Medscape.com)— Tobacco smoking is associated with a 2-fold increased risk for active tuberculosis, according to the results of a prospective Taiwan cohort study reported in the September 1 issue of the American Journal of Respiratory and Critical Care Medicine.
“Previous case-control studies and a small number of cohort studies in high-risk populations have found an association between tobacco and active tuberculosis, but no cohort studies have been conducted in the general population on this association to date,” write Hsien-Ho Lin, MD, ScD, from Harvard School of Public Health in Boston, Massachusetts, and colleagues.
The goal of the study was to evaluate the association between tobacco smoking and active tuberculosis in a general population cohort of 17,699 participants older than 12 years enrolled in the Taiwan National Health Interview Survey. An in-person interview at baseline determined smoking status and other covariates. During follow-up from 2001 to 2004, incident cases of active tuberculosis were identified with use of the National Health Insurance database. After adjustment for age, sex, alcohol intake, socioeconomic status, and other covariates, the association between smoking status and active tuberculosis was estimated with multivariate logistic regression.
During the 3.3 years of follow-up, there were 57 new cases of active tuberculosis. Current smoking was linked to an increased risk for active tuberculosis (adjusted odds ratio [OR], 1.94; 95% confidence interval, 1.01 - 3.73). Compared with patients older than 65 years, those younger than 65 years showed a stronger association between current smoking and the risk for active tuberculosis (adjusted OR, 3.04 vs 0.78; P for interaction = .036). There were significant dose-response associations for cigarettes per day (P for trend = .0036), years of smoking (P for trend = 0.023), and pack-years (P for trend = .0023).
“Tobacco smoking was associated with a twofold increased risk of active tuberculosis in a representative cohort of Taiwan’s population,” the study authors write. “The finding that smoking increases the risk of tuberculosis suggests that tobacco control be considered as an important component in the global effort to eliminate tuberculosis.”

How Cigarettes and Smoking Impact Your Pet’s Health →
Sept 1, 2009 (Mercola.com)—A growing body of research shows there are no safe levels of exposure to secondhand smoke — for humans or for animals. And one new study shows that nearly 30 percent of pet owners live with at least one smoker — a number far too high given the consequences of exposure to secondhand smoke (“SHS”)
An estimated 50,000 Americans lose their lives to secondhand smoke annually and 4 million youth (16 percent) are exposed to secondhand smoke in their homes. A number of studies have indicated that animals, too, face health risks when exposed to the toxins in secondhand smoke, from respiratory problems, allergies and even nasal and lung cancer in dogs and lymphoma in cats. In addition, the ASPCA, one of the largest animal rights groups in the U.S., lists tobacco smoke as a toxin that is dangerous to pets.
“Nicotine from secondhand smoke can have effects to the nervous systems of cats and dogs,” said Dr. Sharon Gwaltney-Brant, Medical Director of the ASPCA’s Animal Poison Control Center. “Environmental tobacco smoke has been shown to contain numerous cancer-causing compounds, making it hazardous for animals as well as humans.
In order to better protect dogs, cats or other pets, the foundation and ASPCA recommend that smokers—who often consider their domestic pets a part of the family—“take it outside” when they are smoking.

Parents Play Key Role In Whether Teen Tobacco Use Becomes A Daily Habit →
Sept 1, 2009 (Sciencedaily.com)—Researchers have found new evidence showing that parents play a key role in whether or not their adolescent children who experiment with tobacco progress to become daily smokers before they graduate from high school.
A study published on-line and in the September issue of journal Pediatrics shows that parents can be a positive or negative influence on their children’s future smoking habit.
“If parents really don’t want their children to smoke they need to communicate that by establishing clear guidelines in their families about not smoking and discuss them with their school-age children.” said Min Jung Kim, a research scientist with the University of Washington’s Social Development Research Group and lead author of the study.
At the same time, parents can increase their children’s chances of smoking by their own use of tobacco.
“If parents smoke, teens have more access to cigarettes than teens who have non-smoking parents. A second preventive measure for smoking parents is to quit smoking themselves,” said Kim.

Reverse Halitosis: Natural Remedies for Bad Breath →
Aug 26, 2009 (NaturalNews.com)— Everyone at some point in their lives has suffered from a horrendous case of morning breath - the type that makes your partner’s eyes water or that the kids cower away from. For most of us the cure is simple, a quick brush followed by a gargle of mouth wash and you are set for the day. But for some this simply isn`t enough and the problem of halitosis or bad breath simply will not go away.
There are a number of different things that can cause halitosis, but having a dry mouth is one of the main culprits. Saliva is the mouth’s natural defense against bacteria. So when your mouth is dry there is no defense against the odor causing molecules that can cause halitosis. Having an excessively dry mouth can be caused by alcohol, certain medicines, stress and some medical conditions. Other causes of halitosis are dental hygiene or lack of it, nasal infections, foods that are high in protein and smoking, which starves the mouth of oxygen.
It can be a very embarrassing problem that has been known to lead to many social and mental problems. Many people who suffer from halitosis simply won`t talk in group situations and refuse to go out as they are afraid that people will be put off by the smell. This type of self seclusion can cause severe depression and has even been known to lead to weight gain as sufferers take up comfort eating to fill the deep void that has taken over their lives.
Cures For Halitosis
As with most ailments there are literally hundreds of old wives’ tales floating around that are said to cure halitosis, but which of them actually work?
Baking soda is involved in a lot of home remedy theories, most of them being completely false. But when it comes to helping cure halitosis there might be something in the baking soda story. Brushing your teeth and tongue with just a little baking soda is thought to make the mouth a little less hospitable and to stop bacteria from growing. You can even buy tooth paste that contains small amounts of baking soda so that there is no need to brush your teeth twice.
Homemade tea tree mouthwashes have become a very popular way of combating halitosis. This is because tea tree is known to be a powerful disinfectant that helps kill bacteria. There are many different ingredients you can add to this such as peppermint to make your breath extra fresh, but the basics are a cup of warm water and a few drops of tea tree oil. Use this to rinse you mouth out at least twice a day and you should notice a massive difference.

Smoking May Worsen Malnutrition →
Aug 24, 2009 (Sciencedaily.com)—A new study finds that smokers in rural Indonesia finance their habit by dipping into the family food budget—which ultimately results in poorer nutrition for their children. The findings suggest that the costs of smoking in the developing world go well beyond the immediate health risks, according to authors Steven Block and Patrick Webb of Tufts University.
The study is published in the October issue of Economic Development and Cultural Change.
Using surveys of 33,000 mostly poor households in Java, Indonesia, the researchers found that the average family with at least one smoker spends 10 percent of its already tight budget on tobacco. Sixty-eight percent of a smoking family’s budget goes to food, and 22 percent for non-food, non-tobacco purchases. The average non-smoking family, on the other hand, spends 75 percent of its income on food and 25 percent for non-food items.
“This suggests that 70 percent of the expenditures on tobacco products are financed by a reduction in food expenditures,” the researchers write.

Acupuncture Proves Successful in Helping People Quit Smoking →
Aug 21, 2009 (NaturalNews.com) —Anyone who has tried to quit smoking knows how hard it can be. The withdrawal symptoms can be too much for many people to cope with for long, and as the stress and edginess builds the first thing they reach for is their trusty old smokes. There are many products and therapies such hypnosis, chewing gum, patches and yoga that all claim to take the edge off and help ease you through the difficult process of quitting smoking. But there is one therapy that many people would never consider, and one that is recommended by the World Health Organization (W.H.O.), acupuncture.
The first thing that many people try on the road to becoming a non-smoker is patches. These patches work by putting the addictive nicotine back in to the body therefore reducing your craving to smoke. The problem is that your body is still used to receiving nicotine, and as soon as you stop wearing the patches you will instantly reach for the smokes to satisfy this craving.
Another popular treatment for people who wish to stop smoking is hypnosis. Hypnosis is meant to work by strengthening your will power. It does this by repeating over and over again that you don’t want to and don’t need to smoke. This is all done while the patient is in a relaxed hypnotic state making the subconscious more open to outside suggestion. Hypnosis practitioners claim that taking part in these sessions will increase your chances of stopping smoking by 1000%. This jump goes from just 6%, with will power alone, to 60% with hypnosis sessions. The main problem with this form of treatment is that you have to believe 100% in hypnosis itself and as there is no real scientific evidence to back it up that can be very difficult for many people.
Acupuncture works by placing long thin needles at specific points all over the body. This will stimulate blood flow, therefore increasing the amount of oxygen that is delivered around your body and the number of toxins that are flushed out. These points are known as acupoints and have been used for thousands of years to help cure all sorts of ailments. But when it comes to smoking acupuncture is so effective because it deals with the main reason that most people smoke in the first place, stress. Experts claim that acupuncture has a success rate of around 85 and 90%, which would make it one of the most successful procedures for helping people quit smoking. The procedure helps relax the mind and releases endorphins in the body. These endorphins will give you an enhanced feeling of wellbeing and will block out any of the negative feelings associated with withdrawal symptoms.

Smokers' Tongues Fail Taste Test →
Aug 20, 2009 (Sciencedaily.com)—Smokers have fewer and flatter taste buds. A study of the tongues of 62 Greek soldiers, published in the open access journal BMC Ear, Nose and Throat Disorders, has demonstrated how cigarettes deaden the ability to taste.
Pavlidis Pavlos led a team of researchers from the Aristotle University of Thessaloniki who used electrical stimulation to test the taste threshold of the soldiers and endoscopes to measure the number and shape of a kind of taste bud called fungiform papillae. He said: “Statistically important differences between the taste thresholds of smokers and non-smokers were detected. Differences concerning the shape and the vascularisation of fungiform papillae were also observed.”

Healthy Lifestyle Habits May Be Associated With Reduced Risk Of Chronic Disease →
Aug 12, 2009 (Sciencedaily.com)—Four healthy lifestyle factors—never smoking, maintaining a healthy weight, exercising regularly and following a healthy diet—together appear to be associated with as much as an 80 percent reduction in the risk of developing the most common and deadly chronic diseases, according to a report in the August 10/24 issue of Archives of Internal Medicine, one of the JAMA/Archives journals.
Cardiovascular disease, cancer and diabetes—chronic diseases that together account for most deaths—are largely preventable, according to background information in the article. “An impressive body of research has implicated modifiable lifestyle factors such as smoking, physical activity, diet and body weight in the causes of these diseases,” the authors write.
To further describe the reduction in risk associated with these factors, Earl S. Ford, M.D., M.P.H., of the Centers for Disease Control and Prevention, Atlanta, and colleagues assessed data from 23,513 German adults age 35 to 65. At the beginning of the European Prospective Investigation Into Cancer and Nutrition–Potsdam (EPIC-Potsdam) study—between 1994 and 1998—participants completed an assessment of their body weight and height, a personal interview that included questions about diseases, a questionnaire on sociodemographic and lifestyle characteristics and a food frequency questionnaire.
Their responses were assessed for adherence to four healthy lifestyle factors: never smoking, having a body mass index lower than 30, exercising for at least three and a half hours per week and following healthy dietary principles (for example, having a diet with high consumption of fruits and vegetables while limiting meat consumption). Follow-up questionnaires were administered every two to three years.
Most participants had one to three of these health factors, fewer than 4 percent had zero healthy factors and 9 percent had all four factors. Over an average of 7.8 years of follow-up, 2,006 participants developed new cases of diabetes (3.7 percent), heart attack (0.9 percent), stroke (0.8 percent) or cancer (3.8 percent).
After adjusting for age, sex, education level and occupation, individuals with more healthy lifestyle factors were less likely to develop chronic diseases. Participants who had all four factors at the beginning of the study had a 78 percent lower risk of developing any of the chronic diseases during the follow-up period than those who had none of the healthy factors. The four factors were associated with a 93 percent reduced risk of diabetes, 81 percent reduced risk of heart attack, 50 percent reduced risk of stroke and 36 percent reduced risk of cancer.
The largest reduction in risk was associated with having a BMI lower than 30, followed by never smoking, at least 3.5 hours of physical activity and then adhering to good dietary principles.
“Our results reinforce current public health recommendations to avoid smoking, to maintain a healthy weight, to engage in physical activity appropriately and to eat adequate amounts of fruits and vegetables and foods containing whole grains and to partake of red meat prudently,” the authors write. “Because the roots of these factors often originate during the formative stages of life, it is especially important to start early in teaching the important lessons concerning healthy living.”

Smoking, Binge Drinking: Double-threat To Teen Health →
Aug 11, 2009 (Sciencedaily.com)—As teens head back to school, health teachers may want to revise their lesson plans. Temple researchers have found that kids who engage in heavy drinking will more than likely also engage in heavy smoking, and they say educators can help combat the trend by addressing both topics as one health risk.
“These are important findings because they emphasize the need for education and intervention programs that target the co-occurrence of these two health risks,” said Brian Daly, assistant professor of public health in the College of Health Professions and Social Work.
Daly and colleagues in the department of public health and psychology determined rates of smoking and binge drinking through the collection of anonymous survey data from 2,450 African-American, Hispanic and Caucasian students in grades 9-12 at Philadelphia public high schools. Students’ responses were compiled from the 2007 Philadelphia Youth Behavioral Risk Survey (YRBS).
Respondents were asked how many cigarettes they’d had per day over 30 days, and how many days over a 30 day period they’d had 5 or more drinks in a row. Data was broken down by race/ethnicity and gender. Researchers found that while Caucasian adolescents were more likely than African-Americans to engage in either binge drinking or smoking, both groups were equally likely to engage in both at the same time.

New Study: Fat in Meat and Dairy Products Increase Pancreatic Cancer Risk →
Aug 5, 2009 (NaturalNews.com)— Cancer of the pancreas, the large organ located horizontally behind the bottom part of the stomach, typically spreads quickly and is usually deadly. Symptoms are often vague at first and a diagnosis is typically not made until the malignancy is advanced and treatment is futile. In fact, the National Cancer Institute (NCI) predicts that almost 42,500 thousand Americans will be diagnosed with pancreatic cancer in 2009 and the vast majority of these people, about 35,250 will die from the disease.
Clearly, the best way to deal with pancreatic cancer is to prevent it in the first place. But how? According to the National Institutes of Health (NIH), the known causes of the disease include long term diabetes, smoking and chronic inflammation of the pancreas (pancreatitis). However, a new study points to another, important and avoidable cause of pancreatic cancer —- specifically, eating fat in red meat and dairy products.
The research, just published online in the Journal of the National Cancer Institute, was conducted because previous studies that attempted to relate fat consumption to the disease reached inconclusive results. But this study concludes the link between dietary animal fat and pancreatic cancer appears to be strong.

Heart Disease Patients With Previous Blockages More Likely To Die →
Aug 5, 2009 (Sciencedaily.com)—Heart disease patients with previous atherosclerosis (fat deposits in the walls of the arteries) are more likely to die in the hospital and less likely to be treated with recommended therapies, researchers report in Circulation: Journal of the American Heart Association.
Researchers analyzed data from the American Heart Association’s Get With The Guidelines - Coronary Artery Disease database to determine whether compliance with quality of care treatment for heart disease was associated with the extent of prior vascular disease. They examined records from 143,999 patients hospitalized in 438 facilities between 2000 and 2008. Overall in-hospital mortality for all patients was 5.3 percent, but those who had previous artery blockages were more likely to die while hospitalized than those who had no prior vascular disease.
They were also less likely to undergo surgery to clear their new blockages, had longer hospital stays and received cholesterol-lowering drugs, counseling to stop smoking and angiotensin-coverting-enzyme (ACE) inhibitors for left ventricular dysfunction less often.
“The results are surprising,” said Emmanouil S. Brilakis, M.D., Ph.D., lead author of the study and director of cardiac catheterization laboratories at Veterans Administration North Texas Healthcare System. “Patients with prior atherosclerosis have a higher risk for complications compared to those without prior atherosclerosis. Therefore, one would expect them to be more likely to receive these evidence-based treatments.”

Dementia risk higher in middle-aged smokers →
Aug 4, 2009 (Presstv.com)—Middle-aged individuals, who smoke and have high blood pressure or diabetes, are placed at a considerable increased risk of developing dementia.
According to a study published in the Journal of Neurology, Neurosurgery and Psychiatry, smoking, diabetes and hypertension are major risk factors contributing to dementia in the long run.
Smokers under the age of 55 are five times more likely to develop dementia. As for diabetics, however, the risk is tripled.
Smoking, high blood pressure and diabetes can damage the brain and its nourishing small blood vessels, leading to dementia.
Scientists therefore pointed out the importance of early lifestyle changes and risk factor treatment to prevent dementia.

Cigarette Packaging Still Misleading Consumers Over Health Hazards →
July 28, 2009 (Sciencedaily.com)—New research suggests that current regulations have failed to remove misleading information from cigarette packaging, revealing that a substantial majority of consumers believe cigarettes are less hazardous when the packs display words such as “silver” or “smooth,” lower numbers incorporated into the brand name, lighter colours or pictures of filters.
In a study of 603 adults published July 28 in the online edition of the Journal of Public Health, Canadian researchers call for the list of words banned from cigarette packaging to be expanded beyond the current prohibition of “light,” “mild” and “low-tar” and suggest that other pack design elements may need to be eliminated to prevent consumers erroneously believing that one brand is less harmful than another.
“Research has already shown that using words such as ‘light,’ ‘mild’ and ‘low tar’ on cigarette packaging misleads consumers into thinking that one brand carries a lower health risk than another and that’s why those words have been outlawed in more than 50 countries, but there has been virtually no independent research on these other packaging tactics to support broader regulation,” said the study’s leader, David Hammond, a professor of health studies at the University of Waterloo in Ontario, Canada. “Our study found that commonly-used words not covered by the bans, as well as other packaging design elements such as colour, the use of numbers and references to filters, were just as misleading, which means there’s a loophole that needs to be closed.”
Tobacco use is the leading cause of preventable death worldwide. The World Health Organization estimates that it kills more than 5 million people a year. Smoking is linked to an increasing number of diseases, including heart disease and stroke, respiratory diseases and 10 different forms of cancer. Globally, use of tobacco products is increasing. Smokers who perceive greater risks are more likely to try to quit and to remain abstinent.
