Wearing Patch 6 Months May Help Smokers Quit
2010-02-05 19:29:00 If you're trying to quit smoking, wearing a nicotine patch for up to six months - far longer than is generally recommended - may increase your chances of staying smoke-free, a new study has found.Even with the longer treatment, however, your chances of successfully quitting are only about one in seven, according to the study, which was funded by the National Cancer Institute and the National Institute on Drug Abuse."There's an assumption that nicotine dependence is an acute disease that can be treated with short-term therapy," says Caryn Lerman, one of the study's authors and the director of the Tobacco Use Research Center at the University of Pennsylvania. "Smokers should talk to their health-care provider about whether it makes sense for them to continue on the nicotine patch for an extended period of time as an alternative to returning to smoking."The patch reduces cravings and withdrawal symptoms by releasing a slow and steady dose of nicotine through the skin.

Mixing herbal remedies and heart drugs is dangerous
2010-02-02 12:58:00 People who take herbal remedies while using heart drugs may face higher risk of cardiac problems, a medical report warns.Some herbal medications affect the activity of prescription drugs for heart troubles, dampening or enhancing their effects, says report author Dr. Arshad Jahangir, a consultant cardiologist at the Mayo Clinic in Arizona.Herbs, if mixed with drugs, could make blood pressure medications and rhythm-controlling medications less effective and might cause serious heart rhythm problems and bleeding, according to the report published in the February issue of the Journal of the American College of Cardiology.Even grapefruit juice, recommended as an aid in weight-loss programs, is problematic in interfering with enzymes that break down drugs in the digestive system, including the statins used to lower cholesterol levels and amiodarone used to treat and prevent abnormal heart rhythms, Jahangir says.Using herbal remedies among the elders is specially problematic because they ...

Five-day Limit for Post-sex Pill
2010-01-29 07:39:00 A recently licensed type of emergency contraception may offer women protection from pregnancy even when taken five days after sex.Scottish researchers found that ulipristel acetate worked well after the three-day limit of the most commonly used drug, levonorgestrel. At present ulipristel - unlike levonorgestrel - is only available with a prescription. The British Pregnancy Advisory Service welcomed the study. Emergency contraception uses hormones to either prevent the release of an egg by the ovary in the hours after sex, or stop it implanting into the the womb. Levonorgestrel is available from pharmacies, either with a prescription, or sold directly to over-16s.A study by specialists working for NHS Lothian tested the effectiveness of levonorgestrel and ulipristel (which was licensed for use last year) using a sample of more than 1,600 women from the UK, Ireland and the USA. A total of 2.6% of the levonorgestrel group became pregnant despite taking the drug, compared with 1.8% in t... More About: Post
Low-Carb Diet Effective in Lowering Blood Pressure
2010-01-26 11:55:00 A new study initiated by researchers at Veterans Affairs Medical Centre and Duke University Medical Centre, reveals that a low-carbohydrate diet is equally effective for weight loss as the weight loss drug orlistat, but in a surprising twist, a low-carbohydrate diet proved more advantageous in lowering blood pressure, as well than the weight-loss medicine.Researcher William S. Yancy, Jr., MD, an associate professor of medicine at Duke University Medical Centre, says, ?If people have high blood pressure and a weight problem, a low-carbohydrate diet might be a better option than a weight loss medication?.The study, published in the Archives of Internal Medicine, involved 146 obese or overweight adults who were randomly segregated into two groups. Among them many were suffering from high blood pressure or diabetes.A low-carbohydrate was imposed on the first group while the second group received the weight loss drug orlistat thrice a day.The results revealed weight loss was similar in t...

Sitting Too Much May Be Deadly
2010-01-24 20:33:00 Here's a new warning from health experts: Sitting is deadly. Scientists are increasingly warning that sitting for prolonged periods - even if you also exercise regularly - could be bad for your health. And it doesn't matter where the sitting takes place - at the office, at school, in the car or before a computer or television - just the overall number of hours it occurs. Research is preliminary, but several studies suggest people who spend most of their days sitting are more likely to be fat, have a heart attack or even die. In an editorial published this week in the British Journal of Sports Medicine, Elin Ekblom-Bak of the Swedish School of Sport and Health Sciences suggested that authorities rethink how they define physical activity to highlight the dangers of sitting. While health officials have issued guidelines recommending minimum amounts of physical activity, they haven't suggested people try to limit how much time they spend in a seated position. "After four hours of sit...
7 Steps for a Healthy Heart
2010-01-21 07:39:00 The American Heart Association has, for the first time, identified seven health factors and lifestyle behaviors its research indicates are necessary to keep your ticker in good shape.?Life?s Simple 7? categorizes cardiovascular health as Poor, Intermediate, or Ideal in each of seven areas.Published in Circulation: Journal of the American Heart Association, the AHA says ideal cardiovascular health for adults is defined by these health measures:Never smoked or quit more than a year ago. A healthy body mass index (BMI), an estimate of body fat determined by a formula using weight and height. Physical activity, and the more the better. The new measure says at least 150 minutes per week of moderate-intensity exercise is necessary for ideal health, or 75 minutes weekly of vigorous physical activity. Blood pressure below 120/80. Fasting blood glucose less than 100 milligrams/deciliter, a fasting measure of blood sugar level. Total cholesterol of less than 200 milligrams/deciliter. Eating...

Chronic sleep loss, sleep debt dangerous
2010-01-16 12:55:00 Humans spend about one-third of their lives asleep, so it's no wonder that we often try to cheat the system by rising early and going to bed late.Many people think they can make up a sleep debt with one or two good nights of rest on the weekend, but new research from Brigham and Women's Hospital suggests this is impossible.Scientists studied healthy volunteers in a sleep lab for three weeks. The participants kept a schedule that was similar to an on-call doctor - 33 hours awake, followed by 10 hours of sleep.On average, this translates to less than six hours of sleep per night. They found that volunteers' reaction times improved after they had a chance to sleep - but this improvement steadily wore off over the course of the day.In the late hours, people's chronic sleep loss caught up with them and caused them to make more errors.Researchers say the resulting sleep debt creates a dangerous situation for late-night drivers or those who work overnights in a hospital.Source: www.wko...

First gene 'linked to aggressive prostate cancer found'
2010-01-12 10:05:00 Scientists have discovered the first gene linked to the aggressive form of prostate cancer, raising hope that doctors will someday be able to predict how the disease will progress.The cancer is often either slow-growing or aggressive, which has led the two types of the disease to be dubbed the ?tiger? and the ?pussycat?.The difference can be crucial as many prostate cancer treatments carry with them the risk of serious side-effects, including incontinence and impotence.However, at the moment there is no way to predict which type a patient will suffer.Although carrying the newly identified gene does not in itself guarantee that a patients? cancer will be aggressive, the breakthrough raises hopes that doctors could someday discover a number of genes that would allow them to predict the diseases? progress accurately.Dr Jianfeng Xu, from Wake Forest University, in North Carolina, who led the study, said: "This finding addresses one of the most important clinical questions of prostate ca...

Study Links Soy to Lower Sperm Counts
2008-07-30 09:51:00 Eating even small amounts of soy products may cut a man's sperm concentration, a study published online last Thursday in the journal Human Reproduction shows. Of the 99 men enrolled in the study, those who said they ate the most soy had much lower sperm concentrations than those who reported eating no soy. Soy eaters had, on average, 41 million fewer sperm per milliliter than those who avoided soy products. That association held up after other factors potentially affecting sperm health, such as smoking, alcohol and caffeine intake, age, abstinence time and body mass index were considered. Still, a man starting with an average sperm count (80 million to 120 million per milliliter) and experiencing such a reduction would measure well above the 20 million that is the minimum count within the normal range, says lead author Jorge Chavarro, a research fellow in the department of nutrition at the Harvard School of Public Health. Consumption of the study's 15 soy-based foods, from miso so... More About: Study , Links , Lower
Hour's exercise 'to lose weight'
2008-07-30 09:14:00 Women who want to lose weight - and keep it off - need to be exercising for almost an hour, five days a week, according to US experts.The University of Pittsburgh study found the 55-minute regime was the minimum needed to maintain a 10% drop in weight. Only a quarter of the 200 women in the study managed to lose this amount. A UK expert said it was clear that regular moderate exercise was the way to lose weight, and keep it off.Approximately two-thirds of adults in the UK are overweight or obese, with some estimates suggesting this could rise to nine in ten by 2050. Research points to a combination of exercise and calorie control as having the best chance of success in weight loss - although the majority of people who attempt these diets fail to keep the weight off. The latest research, published in the Archives of Internal Medicine journal, confirms that plenty of exercise is a key ingredient of success.

Younger Women Often Miss Signs of Heart Attack
2008-05-05 11:22:00 Many younger women ignore or simply don't recognize the warning signs of a heart attack, often because it doesn't resemble the typical "Hollywood heart attack."So say the authors of a study being presented Friday at the American Heart Association's annual Scientific Forum on Quality of Care and Outcomes Research in Cardiovascular Disease and Stroke, in Baltimore."So many women said, 'We wish we had a better stereotype, you never see anything in the media,'" said study author Judith Lichtman, an associate professor of epidemiology and public health at Yale School of Medicine. "I personally would love to see some cutting-edge TV series of, for example, a young person having a heart attack with atypical symptoms.""The classic image of someone having a heart attack is someone like John Belushi. It's a heavy man clutching his chest. We never think of young women as having heart disease, so the image is not part of their consciousness," added Dr. Suzanne Steinbaum, director of Women ...

Chocolate May Cut Diabetes Risk
2008-05-05 11:13:00 Scientists are to investigate whether eating chocolate can reduce the risk of heart disease in women with diabetes.Volunteers - postmenopausal women with type 2 diabetes - will be asked to eat a bar of chocolate a day for a year.Cocoa is rich in compounds called flavonoids, which are thought to benefit the heart.The University of East Anglia is using a specially formulated form of chocolate which contains more flavonoids than usual.This compensates for the fact that many flavonoids are destroyed in the process of turning cocoa into chocolate.Soy - another source of flavonoids - has also been added to the special bars.The scientists are testing the theory that adding flavonoids to the diet may give added protection against heart disease on top of that provided by prescription drugs.Deaths due to heart disease among women increase rapidly after the menopause and having type 2 diabetes increases this risk by a further three-and-a-half times.If the trial confirms the hypothesis then it ...

Use of Hypertension Drugs Leads to Hip Bone Loss in Older Men
2008-04-18 09:28:00 Powerful diuretics, commonly prescribed drugs for heart failure and hypertension, can also steal calcium from the bones and cause significant bone loss in men taking them, study finds.Between 2000 and 2002, Dr. Lionel S. Lim of Griffin Hospital, in Derby, Connecticut and colleagues tested the bone mineral density levels of 3,269 men older than age 65. Patients received follow-up examinations about 4.6 years later. The researchers collected data on medication use and found that 84 men were continuous users of loop diuretics, 181 were intermittent users and 3,004 were non-users.At the end of the study, the researchers found that the average annual rate of decline in total hip bone mineral density was -0.78 among continuous users, -0.58 among intermittent users and -0.33 among nonusers.?Compared with rates of hip bone loss among non-users of diuretics, adjusted rates of loss were about twofold greater among intermittent loop diuretic users and about 2.5-fold greater among continuous lo...

Hypertension Prevents Migraines
