From Dr. Toni Brayer at Everything Health:
We medical folks have always known that July is the worst time for a patient to be admitted to the hospital. It has nothing to do with nice summer weather or staff vacations. Although it cannot be proven, we think the answer to the mystery of July hospital errors is human — yes, it’s the new interns.
A new study published in the June issue of the Journal of General Internal Medicine looked at all U.S. death certificates from 1979 to 2006. They found that in teaching hospitals, on average deadly medication mistakes surged by 10 percent each July. The good news is they did not find a surge in other medical errors, including surgery or in non-teaching hospitals. Read more »

For the first time in history, a living organism has been manufactured with the help of a computer-generated genome. Dr. Jon LaPook reports on the groundbreaking discovery’s widespread implications.
The First Micro-Avatar
Craig Venter and his team of scientists recently announced that they had created the first “synthetic cell” — a bacterium controlled by genetic material that they had designed on a computer and concocted from four bottles of chemicals. This is the closest thing to creating life that has happened outside of a science-fiction movie. If it doesn’t fire your imagination, then you should fire your imagination.
Basically, what Venter et al did was remove the “brain” (the genetic material that runs the cell) from one species of bacteria (Mycoplasma capricolum) and inserted a new brain — one synthetically created based very closely on the known genetic makeup of a second species of bacteria (Mycoplasma mycoides). The new organism then divided just as a normal cell would and followed the instructions of the new brain. Think micro-Avatar, except that the Avatar’s body morphs into one designed by its new brain.

Millions of people with diabetes are forced to endure multiple finger pricks daily — an unpleasant practice that may impede compliance, and whose reliability is operator-dependent.
Now, Dr. Paul Barone and Dr. Michael Strano at the MIT Department of Chemical Engineering are developing a new approach to glucose monitoring.
Building on work they previously published in ACS Nano, the new technology employs a nanoparticle “tattoo” as a glucose sensor, which can then be continuously monitored by a device on the surface of the body. Read more »

The development of drugs and other treatments for specific symptoms or conditions relies heavily on either serendipity (the chance finding of a beneficial effect) or on an understanding of underlying mechanisms.
In pain, for example, there are limited ways in which we can block pain signals –- such as activating opiate receptors, or inhibiting prostaglandins. There are only so many ways in which you can interact with these systems. The discovery of a novel mechanism of modulating pain is therefore most welcome, and has the potential of leading to entirely new treatments that may have a better side effect profile than existing treatments and also have an additive clinical effect.
A recent study by Nana Goldman et. al., published in Nature Neuroscience, adds to our understanding of pain relief by identifying the role of adenosine in reducing pain activity in the peripheral nervous system. The researchers, in a nice series of experiments, demonstrated that producing a local painful stimulus in mice causes the local release of ATP (adenosine triphosphate) that peaks at about 30 minutes. This correlates with a decreased pain response in the mice. Further, if drugs are given that prolong the effect of adenosine, the analgesic effect itself is prolonged. Read more »

It’s no secret that doctors are disappointed with the way that the U.S. healthcare system is evolving. Most feel helpless about improving their work conditions or solving technical problems in patient care. Fortunately one young medical student was undeterred by the mountain of disappointment carried by his senior clinician mentors…
I am proud to be a part of the American Resident Project an initiative that promotes the writing of medical students residents and new physicians as they explore ideas for transforming American health care delivery. I recently had the opportunity to interview three of the writing fellows about how to…
Book Review: Is Empathy Learned By Faking It Till It’s Real?
I m often asked to do book reviews on my blog and I rarely agree to them. This is because it takes me a long time to read a book and then if I don t enjoy it I figure the author would rather me remain silent than publish my…
The Spirit Of The Place: Samuel Shem’s New Book May Depress You
When I was in medical school I read Samuel Shem s House Of God as a right of passage. At the time I found it to be a cynical yet eerily accurate portrayal of the underbelly of academic medicine. I gained comfort from its gallows humor and it made me…
Eat To Save Your Life: Another Half-True Diet Book
I am hesitant to review diet books because they are so often a tangled mess of fact and fiction. Teasing out their truth from falsehood is about as exhausting as delousing a long-haired elementary school student. However after being approached by the authors’ PR agency with the promise of a…
