Exercise cuts cancer death in men
Men who exercise often are less likely to die from cancer than those who don’t exercise, according to a new study from the Swedish medical university Karolinska Institutet. In the study, the researchers looked at the effect of physical activity and cancer risk in 40,708 men aged between 45 and 79.
Over the seven year period of the study, published in the British Journal of Cancer, 3,714 men developed cancer and 1,153 died from the disease. Men who walked or cycled for at least 30 minutes a day had an increased survival from cancer with 33 per cent, than the men who exercised less or did nothing at all. The researchers also found that a more extensive programme of walking and cycling for between 60 and 90 minutes and a day, led to a l6 per cent lower incidence of cancer. But these activities only led to a five per cent reduction in cancer rates among the men who walked or cycled for 30 minutes day, a finding which could be due to chance.
The researchers surveyed men from two counties in central Sweden about their lifestyle and the amount of physical activity they did. They then scored these responses and compared the results with data officially recorded in a central cancer registry over a seven year period.
Residual urine not tied to urinary infection
Among nursing home residents, incomplete bladder emptying is not associated with the occurrence of a urinary tract infection, according to a report in the Journal of the American Geriatrics Society.
It is generally assumed that residual urine after voiding increases the risk for urinary tract infection, “in that it creates an environment favorable to bacterial growth,” Dr. Esther Kuhry from Namsos Hospital, Norway told Reuters Health.
However, she explained, “The few studies published so far show conflicting results with regards to the association of post-void residual and urinary tract infection in the elderly.”
Study shows benefit of statins before heart surgery
People given cholesterol-fighting statin drugs before heart surgery are far less likely to die or suffer complications afterwards, German researchers said on Wednesday.
The analysis of more than 31,000 patients provides some of the strongest evidence yet of the benefits of statins before heart surgery but it also found that too few doctors are prescribing them, they said in the European Heart Journal.
“This is the first big summary of all the existing studies about people undergoing cardiac surgery,” said Oliver Liakopoulos, a researcher at the University of Cologne, who led the study.
Dehydrated Tomatoes Show Promise for Preventing Prostate Cancer
New research suggests that the form of tomato product one eats could be the key to unlocking its prostate cancer-fighting potential, according to a report in the June 1 issue of Cancer Research, a journal of the American Association for Cancer Research.
“Processing of many edible plants through heating, grinding, mixing or drying dramatically increases their nutrition value, including their cancer prevention potential. It appears that the greatest protective effect from tomatoes comes by rehydrating tomato powder into tomato paste,” said Valeri V. Mossine, Ph.D., research assistant professor of biochemistry at the University of Missouri.
The protective effect of tomato products against prostate cancer has been suggested in many studies, but researchers remain uncertain about the exact mechanisms. Mossine and colleagues demonstrated that FruHis, an organic carbohydrate present in dehydrated tomato products, exerts a strong protective effect.
