Too tired for sex? You are not alone
About one in every four Americans married or living with someone say they are so sleep-deprived that they are often too tired to have sex, according to a new study by the National Sleep Foundation. Lack of sleep also keeps many people from work and family functions, the report said. The study, based on a random sampling of 1,007 adults ages 25 to 60, focused on differences in sleep habits among ethnic groups — but the responses on tiredness and sex were about the same across the board. Whites were the most likely — at a rate of about one in 10 — to have received a diagnosis of insomnia. Blacks were the most likely to have sleep apnea, about one in seven. Hispanics were most likely to be kept up at night worrying about work, money, relationships and health problems, with about three in every eight losing sleep over such concerns. Asian-Americans slept the best of all, with five of every six saying they got a good night's sleep at least a few nights a week.
Kidney donors live long lives
People who donate a kidney to a sick friend or relative live at least as long as others in the general population and may, in fact, live somewhat longer because they tend to take better care of themselves after the procedure, researchers reported Tuesday. "We have intuitively . . . felt this way, and hoped that this operation is safe, but this is the first time that we have been able to demonstrate it in a national representation of live donors," said Dr. Dorry L. Sagev of the Johns Hopkins School of Medicine, lead author of the report appearing in the Journal of the American Medical Association. Live-donor kidney transplants have become more common in recent years because of the large number of people who need kidneys and the limited availability of cadaver organs. There are 83,754 Americans waiting for a kidney transplant, a full 80 percent of those waiting for all organs, according to the United Network for Organ Sharing.
Seniors decline after hospital stay
Older people are more likely to suffer a decline in their cognitive abilities after being hospitalized for an illness than they would otherwise, a new study reports. The study, published in the Journal of the American Medical Association, followed almost 3,000 people 65 and older in the Seattle area for more than a decade. Those who were hospitalized for a critical condition like severe infection or cardiac arrest experienced a statistically significant drop in scores on a cognitive performance test given later, when compared with people who had not been hospitalized. Those who had been hospitalized for a noncritical illness faced a 40 percent increase in dementia after the hospitalization. While some of the cognitive impairment could stem from the illness itself, the researchers said, side effects of hospitalization and treatment could also play a role. Low blood pressure, drugs like morphine, infections and systemic inflammation are among the many possible causes of decline after hospitalization, said the lead author, Dr. William J. Ehlenbach, senior fellow in pulmonary and critical care medicine at the University of Washington.
