Model against unnecessary use of antibiotics

Patients in intensive care units (ICU) are often administered antibiotics against ventilator-associated pneumonia, 'to be on the safe side'. Dutch researcher Stefan Visscher has developed a model that can quickly establish whether or not a patient has pneumonia. This can prevent unnecessary treatment with antibiotics.

Prolonging the withdrawal of life support in the ICU affects family satisfaction with care

Clinicians in the intensive care unit (ICU) often care for patients who are on several life support measures at once. When such a patient is dying and the decision is reached to withdraw life support, these clinicians may make an imperfect compromise in seeking to balance the complex needs of the patient and the patient's family - they may remove the life support measures one at a time over a period of days, rather than withdrawing all at once.

Artificial brain-muscle connections used to restore movement to paralyzed limbs

Researchers in a study funded by the National Institutes of Health (NIH) have demonstrated for the first time that a direct artificial connection from the brain to muscles can restore voluntary movement in monkeys whose arms have been temporarily anesthetized. The results may have promising implications for the quarter of a million Americans affected by spinal cord injuries and thousands of others with paralyzing neurological diseases, although clinical applications are years away.

Resveratrol shows promise for treating human alcoholic fatty liver disease

The accumulation of fat in the liver as a result of chronic alcohol consumption could be prevented by consuming resveratrol, according to a new study with mice. The research found that resveratrol reduced the amount of fat produced in the liver of mice fed alcohol and, at the same time, increased the rate at which fat within the liver is broken down.

Discovery of two novel gene locations that raise risk of type 1 diabetes

Genetics researchers have identified two novel gene locations that raise the risk of type 1 diabetes. As they continue to reveal pieces of the complicated genetic puzzle for this disease, the researchers expect to improve predictive tests and devise preventive strategies.

The Internet stimulates and possibly improves brain function

UCLA scientists have found that for computer-savvy middle-aged and older adults, searching the Internet triggers key centers in the brain that control decision-making and complex reasoning. The findings demonstrate that Web search activity may help stimulate and possibly improve brain function.

African-American seniors who have trouble falling asleep are at higher risk of having memory problems

A landmark study led by North Carolina State University researchers shows that African-American seniors who have trouble falling asleep are at higher risk of having memory problems - raising the possibility that identifying and treating sleep difficulties in the elderly may help preserve their cognitive functioning. The study is the first to examine the link between sleep and cognitive functioning in older African-Americans.
