Minimum Alcohol Prices Could Help Low-income, High-risk Drinkers
Setting a minimum price for alcohol would have a positive impact on low-income, high-risk drinkers, but little effect on low-income, moderate drinkers, according to a new study in The Lancet. British researchers at the University of Sheffield utilized a computer model to assess the impact of a 73 cents per unit of alcohol minimum on different demographics, finding it would have the greatest positive impact—reducing the amount of alcohol consumption—on the 5 percent of the population defined as high-risk drinkers. "Our study finds no evidence to support the concerns highlighted by government and the alcohol industry that minimum unit pricing would penalize responsible drinkers on low incomes,” said study co-author Petra Meier, director of the Sheffield Alcohol Research Group. “Instead, minimum unit pricing is a policy that is targeted at those who consume large quantities of cheap alcohol. By significantly lowering rates of ill health and premature deaths in this group, it is likely to contribute to the reduction of health inequalities." Read more on alcohol.
Smoking Linked to Most Common Type of Breast Cancer
Adding yet another health risk to the use of tobacco, smoking is linked to an increased risk for the most common type of breast cancer, according to a new study in the journal Cancer. Researchers at the Fred Hutchinson Cancer Research Center in Seattle conducted a population-based study of 778 patients, ages 20-44, with estrogen receptor positive breast cancer (the most common type) and 182 patients with triple-negative breast cancer; there were 938 cancer-free controls. They found that women who were current or recent smokers and had been smoking a pack a day for at least 10 years had a 60 percent increased risk of estrogen receptor positive breast cancer. "The health hazards associated with smoking are numerous and well known. This study adds to our knowledge in suggesting that with respect to breast cancer, smoking may increase the risk of the most common molecular subtype of breast cancer but not influence risk of one of the rarer, more aggressive subtypes," said Christopher Li, MD, PhD.

Low Testosterone Drugs Can Double Heart Attack Risk in Some Men
Ads asking men about their “low T”—or low testosterone levels—have become so common of late that in 2013 sales of the testosterone gel Androgel exceeded those of Viagra. However, a recent study indicates that men under the age of 65 with a history of heart disease see their heart attack risk double shortly after beginning testosterone therapy. The joint study from the UCLA Fielding School of Public Health, the National Institutes of Health and Consolidated Research Inc. appears in the journal PLOS ONE. Researchers decided to perform this larger study after three smaller studies raised concerns about the connection. "We decided to investigate cardiovascular risks of this therapy in a large health care database since these previous studies were modest in size and only focused on men 65 and older," said the study's senior author, Sander Greenland, MD, a professor of epidemiology at the UCLA Fielding School of Public Health and a professor of statistics in the UCLA College of Letters and Science. "Our study allowed us to examine cardiovascular risk in men under the age of 65 and to replicate the findings in men over 65." Read more on heart health.
