When 32 Million New Patients Look For A Doctor
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 »
What You Should Know About Stem Cell Research
Camouflaged in the politics, controversy, and hype surrounding stem cells have been two stunning and unexpected dividends: the ability to study diseases in a petrie dish and a new way to think about cancer. This is separate from the most well-publicized stem cell story: the potential of embryonic stem cells to morph into any cell in the body and replace injured or defective cells — for example in diabetes, Parkinson’s, and spinal cord injury.
Human embryonic stem cells (HES cells) are collected from unused embryos created by in-vitro fertilization. About two years ago, scientists figured out a way to turn ordinary skin cells into stem cells. This was a huge deal. These cells — called “induced pluripotents stem cells” (IPS cells) — are not identical to HES cells and may not be quite as nimble in morphing into other cells. But they are electrifying the field because diseases can now be studied outside the body – in a petrie dish. For example, researchers have taken skin from patients with ALS (Lou Gehrig’s disease), turned them into stem cells, then turned the stem cells into the kind of nerve cells (motor neurons) damaged in the disease.

CBS News’ Dr. John LaPook: Do Happy People Live Longer?
For decades, research has suggested that people with positive emotions may live longer and healthier lives. An analysis of the autobiographical writings of 180 Catholic nuns found those with the most positive feelings in their early twenties had the greatest chance of being alive sixty years later. Now, the first study of its kind has linked positive emotions to a lower risk of coronary heart disease. Read more »
How Much Does Technology Improve Health?
Last week’s CDC report, “Health, United States, 2009” confirms that Americans are increasingly turning to medications, scans, and procedures to improve their health. Exercising, eating right, and weight loss: not so much.
Don’t get me wrong. I love technology as much as the next guy. Maybe more. I’m writing this on a laptop while jetting from California to New York. My iPhone, Blackberry, and Kindle are all within ten feet of me. But my inner Luddite is starting to stir. Read more »
