Lower income patients less informed about cancer treatments
Prostate cancer patients from lower income brackets are less informed about their treatment options, less likely to seek a second opinion and more often unhappy with their treatment decision than patients from higher income brackets.  more

What measures persuade people to shift from using cars to walking and cycling?
Transport policies aim to reduce traffic congestion by discouraging car use and encouraging alternative modes of transport, such as walking and cycling. A shift in population transport patterns has obvious potential health benefits, but we lack good evidence on what measures are effective.  more

Childhood influenza vaccination coverage, US, 2002-2003 influenza season
A report issued 23 September 2004, by the Centers for Disease Control and Prevention (CDC) estimates that only 4.4 percent of the nationís children aged 6 to 23 months were fully vaccinated against influenza during the 2002-03 influenza season, the first season CDC encouraged influenza vaccination for healthy children. This first CDC report on childhood influenza vaccination coverage also estimates that only 7.4 percent of the children aged 6 to 23 months had received at least one dose of the vaccine.  more


NIH stem cell backgrounder
Stem cells have the remarkable potential to develop into many different cell types in the body. Serving as a sort of repair system for the body, they can theoretically divide without limit to replenish other cells as long as the person or animal is still alive. When a stem cell divides, each "daughter" cell has the potential to either remain a stem cell or become another type of cell with a more specialized function.  more

NIH gene transfer backgrounder
Human gene transfer is the process of transferring genetic material (DNA or RNA) into a person. This experimental technique is being studied to see whether it could treat certain health problems by either compensating for defective genes, prompting the body to make a potentially therapeutic substance, or triggering the immune system to fight disease.  more

Stress and aggression reinforce each other at the biological level
Scientists may be learning why it's so hard to stop the cycle of violence. The answer may lie in the nervous system. There appears to be a fast, mutual, positive feedback loop between stress hormones and a brain-based aggression-control center in rats, whose neurophysiology is similar to ours. It may explain why, under stress, humans are so quick to lash out and find it hard to cool down. The findings, which could point to better ways to prevent pathological violence, appear in the October issue of Behavioral Neuroscience, which is published by the American Psychological Association (APA). more

Cornell gerontologists say elder abuse is pervasive and requires urgent response
A substantial number of older persons -- from 2 to 10 percent of the elderly population -- are physically or mentally abused, and mistreated seniors are three times more likely to die within three years than those who are not abused, report two Cornell University gerontologists in this week's issue of the medical journal The Lancet.  more
