Men with prostate cancer who take cholesterol-lowering drugs called statins are significantly less likely to die from their cancer than men who don’t take such medication, according to a study published online in The Prostate. The risk of death from prostate cancer among statin users was 1 percent as compared to 5 percent for nonusers.
Researchers at the University of California, Berkeley’s School of Public Health tested 32 different lipsticks and lip glosses commonly found in drugstores and department stores. They detected lead, cadmium, chromium, aluminum and five other metals, some of which were found at levels that could raise potential health concerns. Their findings were published online Thursday, May 2, in the journal Environmental Health Perspectives.
A study appearing in the Journal of Nutritional Biochemistry demonstrates that grapes are able to reduce heart failure associated with chronic high blood pressure (hypertension) by increasing the activity of several genes responsible for antioxidant defense in the heart tissue. Grapes are a known natural source of antioxidants and other polyphenols, which researchers believe to be responsible for the beneficial effects observed with grape consumption.
Elderly people who played just ten hours of a game priming their mental processing speed and skills delayed declines by as many as seven years in a range of cognitive skills. The groups that played the game at least 10 hours, either at home or in a lab at the university, gained at least three years of cognitive improvement when tested after one year, according to a formula developed by the researchers. A group that got four additional hours of training with the game did even better, improving their cognitive abilities by four years, according to the study.
The study comes amidst a burst of research examining why, as we age, our minds gradually lose “executive function,” generally considered mission control for critical mental activities, such as memory, attention, perception and problem solving. Studies show loss of executive function occurs as people reach middle age; other studies say our cognitive decline begins as soon as 28 years of age.
The largest study to date finds that eating foods that contain omega-3 fatty acids, found in fish, chicken and salad dressing and avoiding saturated fats, meat and dairy foods may be linked to preserving memory and thinking abilities. The research is published in the April 30, 2013, print issue of Neurology®, the medical journal of the American Academy of Neurology. The study found that in healthy people, those who more closely followed the Mediterranean diet were 19 percent less likely to develop problems with their thinking and memory skills.
Three new studies involving tree nuts (almonds, Brazil nuts, cashews, hazelnuts, macadamias, pecans, pine nuts, pistachios and walnuts) were presented at the Experimental Biology Meeting in Boston, MA. Tree nut consumption was associated with a better nutrient profile and diet quality; lower body weight and lower prevalence of metabolic syndrome; and a decrease in several cardiovascular risk factors compared to those seen among non-consumers.
A high heart rate (pulse) at rest is linked to a higher risk of death even in physically fit, healthy people, suggests research published online in the journal Heart. A resting heart rate – the number of heart beats per minute – is determined by an individual’s level of physical fitness, circulating hormones, and the autonomic nervous system. A rate at rest of between 60 and 100 beats per minute is considered normal.
