Journalist Larry Husten, on his Cardiobrief blog, writes, “Hype Aside, Hope for Stem Cell Therapy May Be Emerging From Hibernation.”
It was one of the only notes of caution we saw in our limited sampling of news stories about an analysis of an experimental stem cell intervention in 14 people – only 8 of whom were followed for a year. Husten wrote:
“Two small studies of cardiac stem cells for the treatment of heart failure have shown promise, but ABC News, CBS News and other media outlets are throwing around words like “medical breakthrough” and “heart failure cure.” ABC News correspondent Richard Besser was so enthusiastic that anchor Diane Sawyer commented that she had never seen him “so excited.” The first author of one of the studies, Roberto Bolli, said the work could represent “the biggest advance in cardiology in my lifetime.”
The reality may be somewhat more prosaic.” Read more »

1. Health care reform
How could the health care reform legislation that President Barack Obama signed into law on March 23, 2010, not be the #1 story of the year? Whether you are for or against it, the Patient Protection and Affordable Care Act is nothing if not ambitious, and if implemented, it will fundamentally alter how American health care is financed and perhaps delivered. The law is designed to patch holes in the health insurance system and extend coverage to 32 million Americans by 2019 while also reining in health care spending, which now accounts for more than 17% of the country’s gross domestic product. The biggest changes aren’t scheduled to occur until 2014, when most people will be required to have health insurance or pay a penalty (the so-called individual mandate) and when state-level health insurance exchanges should be in place. The Medicaid program is also scheduled to be expanded that year so that it covers more people, and subsidized insurance will be available through the exchanges for people in lower- and middle-income brackets. But plenty is happening before 2014. The 1,000-page law contains hundreds of provisions, and they’re being rolled out in phases. This year, for example, the law created high-risk pools for people with pre-existing conditions, required health plans to extend coverage to adult children up to age 26, and imposed a 10% tax on indoor tanning salons. Next year, about 20 different provisions are scheduled to take effect, including the elimination of copayments for many preventive services for Medicare enrollees, the imposition of limits on non-medical spending by health plans, and the creation of a voluntary insurance that will help pay for home health care and other long-term care services received outside a nursing home. Getting a handle on the complicated law is difficult. If you’re looking for a short course, the Kaiser Family Foundation has created an excellent timeline of the law’s implementation (we depended on it for this post) and a short (nine minutes) animated video that’s one of the best (and most amusing) overviews available. The big question now is whether the sweeping health care law can survive various legal and political challenges. In December, a federal judge in Virginia ruled that the individual mandate was unconstitutional. Meanwhile, congressional Republicans have vowed to thwart the legislation, and if the party were to win the White House and control of the Senate in the 2012 election, Republicans would be in a position to follow through on their threats to repeal it.
2. Smartphones, medical apps, and remote monitoring
Smartphones and tablet computers are making it easier to get health care information, advice, and reminders on an anywhere-and-anytime basis. Hundreds of health and medical apps for smartphones like the iPhone became available this year. Some are just for fun. Others provide useful information (calorie counters, first aid and CPR instructions) or perform calculations. Even the federal government is getting into the act: the app store it opened this summer has several free health-related apps, including one called My Dietary Supplements for keeping track of vitamins and supplements and another one from the Environmental Protection Agency that allows you to check the UV index and air quality wherever you are. Smartphones are also being used with at-home monitoring devices; for example, glucose meters have been developed that send blood sugar readings wirelessly to an app on a smartphone. The number of doctors using apps and mobile devices is increasing, a trend that is likely to accelerate as electronic health records become more common. Check out iMedicalapps if you want to see the apps your doctor might be using or talking about. It has become a popular Web site for commentary and critiques of medical apps for doctors and medical students. Meanwhile, the FDA is wrestling with the issue of how tightly it should regulate medical apps. Some adverse events resulting from programming errors have been reported to the agency. Medical apps are part of a larger “e-health” trend toward delivering health care reminders and advice remotely with the help of computers and phones of all types. These phone services are being used in combination with increasingly sophisticated at-home monitoring devices. Research results have been mixed. Simple, low-cost text messages have been shown to be effective in getting people wear sunscreen. But one study published this year found that regular telephone contact and at-home monitoring of heart failure patients had no effect on hospitalizations of death from any cause over a six-month period. Another study found that remote monitoring did lower hospital readmission rates among heart failure patients, although the difference between remote monitoring and regular care didn’t reach statistical significance.

From The Australian:
Stem cell researchers have found a way to turn a person’s skin into blood, a process that could be used to treat cancer and other ailments, according to a Canadian study published today.
The method uses cells from a patch of a person’s skin and transforms it into blood that is a genetic match, without using human embryonic stem cells, said the study in the journal Nature.
Wow. Very cool. I wonder if hopefully someday this could be a replacement for random blood donation?

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.
