Study shows increase in U.S. population living with more than one chronic illness
WASHINGTON The number of people in the United States with multiple chronic diseases has increased, according to a study released Tuesday.
The study, published in the journal Health Affairs, found that the increase in chronic diseases has resulted in a large rise in out-of-pocket medical expenditures, from $427 annually per person to $741 in 2005, or a 39 percent increase.
According to the study, the increase in chronic diseases has resulted in the increase in sedentary lifestyles and obesity. The percentage of people with three or more chronic diseases has increased as well, from 13 percent in 1996 to 22 percent in 2005 among Americans aged 45 to 64.
Researchers test administering medication using nanotechnology, gold
NEW YORK Researchers have developed a way to use tiny particles of gold to control the administration of drugs for diseases such as cancer, according to a study published in the journal ACS Nano.
The researchers, at the Massachusetts Institute of Technology, created a device that shines infrared light on particles of gold coated with medicine.
The particles vary in size, causing them to melt at different rates depending on the intensity of the light.
The researchers said the device would allow medicine to target specific areas of the body at specific rates, thus minimizing damage to healthy tissue.
