The New York Times profiles research by Harvey A. Liu and Kenneth J. Balkus Jr. of the University of Texas at Dallas to create a therapeutic nitric oxide releasing bandage. Nitric oxide can play a significant role in peripheral vasodilation, relaxation of pulmonary vasculature, and other physiological processes, such as penile erection. Therefore, an effective method of delivering this free radical should allow the development of new types of vascular stockings, bandages, and other therapeutic (or recreational) devices.
A snippet from NYT:
As they describe in a paper in Chemistry of Materials, the researchers use a zeolite, an aluminosilicate mineral that has a three-dimensional cage structure. Zeolites have been shown to be able to store and release nitric oxide and other chemicals. They embed the mineral in fibers of a biocompatible polymer, polylactic acid, as they are spun and form a tissue-like mat. The fibers are then infused with nitric oxide; by controlling the porosity of the fibers, the researchers could control the release of the gas.
The researchers say the resulting material could be incorporated into socks for diabetics that would deliver nitric oxide through the skin. It might also prove useful before transplants as a wrapping for organs to help preserve them outside the body for longer.

In a recent issue of Wilderness and Environmental Medicine (Volume 20, Number 2, 2009), Thomas Welch and colleagues have written an article entitled “Wilderness First Aid: Is There an Industry Standard?” The purpose of their inquiry was to determine if an “industry standard” exists for wilderness first aid training and certification of outdoor adventure and education leaders. To attempt to answer the question, they queried regulatory authorities, national organizations, and school/college groups with regard to their requirements for first aid training of their wilderness trek leaders.
They discovered that 10 or the 22 states with guide licensure programs required any first aid training as a condition of licensure, and none specified a specific course. Of the programs requiring such training, the requirements ranged from a 6-hour standard first aid course to more structured “wilderness first responder” (WFR or “woofer”) certification. Read more »

Count the pens. News reports said that the president signed healthcare reform into law with either 20 (The New York Times) or 22 pens (Everyone else). The White House posted the ceremony on YouTube so you can count for yourself, starting at 25 minutes into the 27-minute ceremony, when Mr. Obama quips: “This is going to take a little while.”
The pens hits the page 22 times. But there’s only 11 letters in “Barack Obama” (add seven more for his middle name), so he’s clearly having to sign partial letters.
There’s a long history to this practice, which creates historical artifacts and gifts. President Kennedy used his middle name and flourishes to stretch things out. President Lyndon Johnson used 75 pens to sign the Civil Rights Act, with one of the first going to Martin Luther King, Jr., and then key legislators. Here’s a list of who’ll get the 22 pens.

Virtobot is the name of a forensic robot used at the University of Bern’s Institute of Forensic Medicine to perform virtual autopsies. In the futuristic Virtopsy laboratory, the robot scans the contours and texture of the human body by projecting light bars on it and acquiring high definition images.
These data are combined with the CT images acquired by the scanner in the same room. A three dimensional image of the body is then reconstructed that can be used during forensic examinations and be preserved as long as necessary. Additionally, the robot can also perform CT guided biopsies. The US forces have already installed a Virtopsy laboratory at Dover Air Force Base in Delaware to assess the cause of death of soldiers sent back from Iraq and Afghanistan.

With the passage of healthcare reform, an estimated thirty two million new patients will try to find primary care doctors. That’s not going to be so easy because we already face a shortage of primary care doctors and about 13,000 more will be needed to take care of those newly eligible for insurance.
According to the American Medical Association, there are about 312,000 primary care doctors practicing in the United States. That includes family medicine, general practice (GP), internal medicine, and pediatrics. (In addition, there are 43,000 ob-gyn’s who also may serve as primary care doctors.) The estimate that another 13,000 will be needed comes from a study done by the Robert Graham Center for Policy Studies in Family Medicine and Primary Care in partnership with the Agency for Healthcare Research and Quality.
Sixty five million Americans already live in areas that don’t have enough primary care doctors. And relief is not on the way anytime soon. It takes 5 to 8 years for a first year medical student to be trained as a primary care doctor. And the trend for budding doctors over the past decade has been away from primary care and towards more lucrative specialties. Read more »
