New Report Confirms Laws Regulating Alcohol Availability Help Reduce Associated Problems

By Leave a Comment

A newly released report shows that increasing the number of hours and days when alcohol can be sold in bars, restaurants, and liquor stores leads to greater alcohol use and related harms, especially motor-vehicle crashes. National, state, and local policies that remove previously banned alcohol sales on weekend days (usually Sundays) or that increase the hours of sale by 2 or more hours contribute to excessive drinking and many dangerous outcomes, including driving after drinking and alcohol-related assault and injury.

The Task Force on Community Preventive Services, an independent, nonfederal body of public health experts, recommends maintaining limits on the days or hours during which alcohol can legally be sold, based upon a state-of-the-art systematic review process of all available studies on the topic.

Regular Drinking May Reduce the Risk of Rheumatoid Arthritis

By 1 Comment

Drinking alcohol regularly may reduce the risk of developing rheumatoid arthritis by up to 50%, according to recent research.

Scandinavian researchers conducted two studies, involving 2,750 people, assessing environmental and genetic risk factors for rheumatoid arthritis. 1,650 participants had the disease, and were questioned about their smoking and drinking habits, while blood samples were taken to check for genetic risk factors.

Findings showed that drinking alcohol was linked to a reduced risk of developing rheumatoid arthritis; in fact, the more the subject drank, the lower the risk of rheumatoid arthritis.

Among regular drinkers, the quartile drinking the most were up to 50% less likely to develop the disease than the half who drank the least. Findings were the same for both men and women. In addition, alcohol cut the risk most in smokers with genetic risk factors for rheumatoid arthritis.

The authors conclude that their research reinforces the importance of lifestyle factors in the development of the disease, and that giving up smoking remains the single most important preventive measure.

They point to recent experimental research by other authors, which shows that alcohol protects against the development and severity of rheumatoid arthritis, although it is not clear exactly how it does this. The study also draws parallels with the links between moderate alcohol consumption and a reduced risk of other inflammatory processes, such as cardiovascular disease.

The study was published in the Annals of the Rheumatic Diseases.

Alcohol May Cause Lower Brain Volume

By Leave a Comment

According to a recent report, the more you drink the smaller your brain becomes. It is estimated that 1.9 percent decrease in brain volume per decade accompanies an increase in white matter lesions.

The progression of dementia and problems with thinking, learning and memory are accompanied by lower brain volumes and larger white matter lesions. Moderate alcohol consumption has been associated with a lower risk of cardiovascular disease; because the brain receives blood from this system, researchers have hypothesized that small amounts of alcohol may also attenuate age-related declines in brain volume. The study results were published in the October, 2008 issue of Archives of Neurology.

Members of the Framingham Offspring Study, which began in 1971 and included 1,839 adults with an average age of 60, were studied by Carol Ann Paul, M.S., of Wellesley College, Mass., and colleagues. The Study also included children of the original Framingham Heart Study participants and their spouses. Between 1999 and 2001, participants underwent magnetic resonance imaging (MRI) and a health examination. They reported the number of alcoholic drinks they consumed per week, along with their age, sex, education, height, body mass index and Framingham Stroke Risk Profile (which calculates stroke risk based on age, sex, blood pressure and other factors).

“Most participants reported low alcohol consumption, and men were more likely than women to be moderate or heavy drinkers,” the authors write. “There was a significant negative linear relationship between alcohol consumption and total cerebral brain volume.”

Although men were more likely to drink alcohol, the association between drinking and brain volume was stronger in women, they note. This could be due to biological factors, including women’s smaller size and greater susceptibility to alcohol’s effects.

“The public health effect of this study gives a clear message about the possible dangers of drinking alcohol,” the authors write. “Prospective longitudinal studies are needed to confirm these results as well as to determine whether there are any functional consequences associated with increasing alcohol consumption. This study suggests that, unlike the associations with cardiovascular disease, alcohol consumption does not have any protective effect on brain volume.”

Three Alcohol Drinks Per Day May Significantly Increase Breast Cancer Risk

By Leave a Comment

It isn’t the type of alcohol but the quantity which increases a woman’s risk of contracting breast cancer.

In fact, the increased breast cancer risk from drinking three or more alcoholic drinks a day is similar to the increased breast cancer risk from smoking a pack of cigarettes or more a day, according to Kaiser Permanente researchers Yan Li, MD, PhD and Arthur Klatsky, MD.

"Population studies have consistently linked drinking alcohol to an increased risk of female breast cancer, but until now there has been little data, most of it conflicting, about an independent role played by the choice of beverage type," said Klatsky, who is presentied these findings on Sept. 27 at the European Cancer Conference (ECCO 14) in Barcelona, Spain.

The study found there was no difference between wine, beer or spirits in the risk of developing breast cancer. Even when wine was divided into red and white, there was no difference. However, when researchers looked at the relationship between breast cancer risk and total alcohol intake, they found that women who drank between one and two alcoholic drinks per day increased their risk of breast cancer by 10 percent compared with light drinkers who drank less than one drink a day. The risk of breast cancer increased by 30 percent in women who drank more than three drinks a day.

"A 30 percent increased risk is not trivial. To put it into context, it is not much different from the increased risk associated with women taking estrogenic hormones. Incidentally, in previous research completed at Kaiser Permanente, we have found that smoking a pack of cigarettes or more per day is related to a similar (30 percent) increased risk of breast cancer," Klatsky said.

Although breast cancer incidence varies between populations and only a small proportion of women are heavy drinkers, Dr Klatsky said that a 30 percent increase in the relative risk of breast cancer from heavy drinking might translate into approximately an extra 5 percent of all women developing breast cancer as a result of their habit.

"Klatsky said that all medical advice needed to be personalized to the individual. "Our findings provide more evidence for why heavy drinkers should quit or cut down."

Epilepsy Drug Topamax Helps Alcoholism Treatment

By 1 Comment

A drug called Topamax (topiramate) has been found to help alcoholics quit drinking excessively, according to a University of Virginia study. The drug is not FDA approved for treatment of alcoholism, but has been prescribed off-label by doctors to treat the condition.

Topiramate (brand name Topamax) is an anticonvulsant drug produced by Ortho-McNeil Neurologics, a division of Johnson & Johnson. The drug is FDA-approved for treatment of epilepsy and for the prevention of migraines.

To test the drug’s efficacy in treating alcoholism, researchers conducted a 14-week study of 317 alcoholics. Half of the participants were given a placebo and the other half were given Topamax.

The study found that participants on Topamax reduced their alcohol intake from 11 drinks per day on average, to just 3.5 drinks per day. Furthermore, while only abstaining from drinking 3 days per month at the start of the study, by the end of the study they were abstaining from drinking about 15 days per month.

The placebo group also drank less during the study. However, by the end of the study, they abstained from drinking 10 days per month and consumed six drinks per day on average.

The most common side effects of Topamax include a change in taste (carbonated beverages, especially diet sodas and beer, taste particularly bad) and feelings of pins and needles in the head and extremities. Less common side effects include cognitive deficiency (particularly word-finding difficulty); grogginess; lethargy; renal stones, impairment of fine motor skills; vision abnormality and transient or permanent vision loss; weight loss; breast pain; abdominal pain; intense sweating; menstrual disorder; taste changes; pharyngitis; sinusitis; diplopia; rash; leukopenia; fatigue; dizziness; insomnia; anxiety; depression; paresthesia; diarrhea; nausea; dyspepsia; constipation; dry-mouth; dysmenorrhea.

Anti-Smoking Drug Varenicline May Help Curb Drinking

By Leave a Comment

A single pill appears to hold promise in curbing the urges to both smoke and drink, according to researchers trying to help people overcome addiction by targeting a pleasure center in the brain.

The drug, called varenicline, already is sold to help smokers kick the habit. New but preliminary research suggests it could gain a second use in helping heavy drinkers quit, too.
