Wide Disparities in Health Care by Race and Region
Most of us would agree race could be a determining factor in the quality of service a person gets. But a new study shows place of residence could play a role in quality of the medical treatment a patient receives. According to a new study in United States that women in Mississippi are far less likely to have mammograms than those in Maine. The study also revealed that blacks with diabetes or vascular disease are nearly five times more likely than whites to have a leg amputated. “In U.S. health care, it’s not only who you are that matters; it’s also where you live,” wrote the study’s authors, led by Dr. Elliott S. Fisher.

Green Or Blue Scrubs Over White
Why do health care professionals wear blue or green scrubs rather than any other colours? Although white is the color of cleanliness, in the early 20th century doctors switched their scrub’s colour from white to green. It’s been known that green or blue colours are easier on a surgeon’s eyes and help doctors to see better in the operating room due the opposite of red on the color wheel.
Looking at blue or green can refresh a one’s vision of red things, especially during surgery. If a surgeon looks at something red, he becomes desensitized to it. The red colour signal in the brain actually fades, and this could make the surgery difficult. Looking at something green will make the eyes more sensitive to red. By wearing a green scrub, doctors can also eliminate a green illusion of the blood (“after effect” illusion due to red).

Health And Moon Dust
Since lungs are a highly sensitive organ that delivers oxygen molecules through a thin membrane directly to the blood, researchers are concerned about astronauts’ health. Long term exposure to lunar dust will increase the dust particles go deeper into the lungs, and this could be lethal.
But researchers are unsure about the consequences, so they have designed lunar bases to get more information on particle size, gravity and deposition rate. This could benefits for healthcare on Earth, such as improved delivery of aerosol medications to the lungs.
