Many middle-aged and older adults with diabetes are sexually active according to a study of nearly 2,000 people aged 57 to 85 presented in the September 2010 issue of the journal Diabetes Care. Almost 70 percent of partnered men with diabetes and 62 percent of partnered women with diabetes engaged in sexual activity two or three times a month, comparable to those without diabetes, the study showed. http://phys.org/news202060795.html Medicine & Health Fri, 27 Aug 2010 00:00:01 EST news202060795 (PhysOrg.com) -- Commonly prescribed drugs used to lower blood pressure can actually have the opposite effect -- raising blood pressure in a statistically significant percentage of patients. A new study by researchers at Albert Einstein College of Medicine of Yeshiva University suggests that doctors could avoid this problem -- and select drugs most suitable for their patients -- by measuring blood levels of the enzyme renin through a blood test that is becoming more widely available. The study appears in the August online edition of the American Journal of Hypertension. http://phys.org/news201423698.html Medicine & Health Thu, 19 Aug 2010 08:02:02 EST news201423698 Drinking alcohol may reduce the severity of rheumatoid arthritis according to new research published today.
