How Loud? Almost Chainsaw Level

1 Hospital Noise Exceeds Recommendations

The World Health Organization suggests that the noise level in hospital rooms not exceed 30 to 40 decibels, but a University of Chicago study published in the Archives of Internal Medicine has found that the actual noise level in patient rooms averaged almost 50 decibels, the equivalent of an air conditioner or electric shaver, and occasionally peaked out at 80, equal to an alarm clock or ringing phone and close to the noise level of a chainsaw. Although the problem was much worse in the daytime than at night, and generally due to intercom messages and alarms, noise levels at night were still higher than health officials' recommendations, and patients often report sleep disruptions and restlessness, and an average of an hour less sleep than they typically get at home.

Same Detail As Full-Body Scan

2 New Extremities MRI Ends Claustrophobia

A new MRI machine designed for arms and legs produces images as detailed as full-body MRIs but eliminates stress and claustrophobia. For the new MRI, known as the 1.5 Tesla, patients remain seated while their arm or leg is inserted into a tube. Traditional MRIs, where the patient lies down and is inserted into a 6-foot long tube surrounded by a circular magnet, may present problems for those with back pain, obstructive pulmonary disease or claustrophobia. Even healthy patients have found it difficult to hold position in traditional MRIs. The new MRI eliminates discomfort and “the more comfortable the patient is the better it is for our images,” says Dr. Albert Song, Loyola U, which has one of the new MRIs. Currently, there are 33 of the new MRI machines in use in the US.

Inhibits Mutant P53 Pathway

3 Statins Inhibit Mutant Gene Tied to Cancer

Research out of Columbia University in NYC suggests that statins, used to lower cholesterol, may prevent or treat cancers with a mutated p53 gene. p53 is known as the "guardian of the cell" and either sends damaged cells back into the cell cycle to be repaired or tells them to die. In vitro experiments with breast cancer cells showed that treatment with statins inhibited their growth and killed them. The mutated p53 gene activates the mevalonate pathway which plays a crucial role in cholesterol production while statins block it. This was confirmed when the pathway was reactivated once statins were removed. While researchers are excited, they stress that use in humans is not going to happen right away and that people with cancer would have to be tested for a mutated p53 gene.
