Blood Management Summit and App - Transfuse 2012

Announcement: Blood Management Summit - Transfuse 2012 will be held on April 19-20, 2012 at the JW Marriott in Scottsdale, Arizona.

This conference has been developed with collaboration between Mayo Clinic and Hartford Hospital, building upon the success of three previous national conferences. "Transfuse 2012" is a unique multi-disciplinary conference focused on exploring the current state-of-the-art techniques and programs to reduce allogeneic blood utilization in hospitals. This international conference will feature national and international blood management experts from China, New Zealand and Australia along with a unique iPad app launch and one-of-a-kind hands-on animal lab.

Mayo Clinic's Mark H. Ereth, M.D. introduces the conference and the iPad app in this 3-minute video:



This conference is designed for all physicians, including surgeons and anesthesiologists, perfusionists, nurses and leaders in quality and patient safety. The conference is a CME accredited activity for physicians, nurses and perfusionists.

The Conference Website is: http://www.mayo.edu/cme/anesthesiology-2012r780

One of the course directors is Dr. Ajay Kumar, Chief of Division of Hospital Medicine at Hartford Hospital, and a good friend of mine. Another friend from the time I worked at Cleveland Clinic is also on faculty, Dr. Moises Auron.

It should be a great conference. Go check it out.

How the heart actually pumps blood - TED-Ed animation

For most of history, scientists weren't quite sure why our hearts were beating or even what purpose they served. Eventually, we realized that these thumping organs serve the vital task of pumping clean blood throughout the body. But how? Edmond Hui investigates how it all works by taking a closer look at the heart's highly efficient ventricle system.

Contact lenses change color when blood glucose increases in diabetics

In the future, diabetics may be able to wear contact lenses that continuously alert them to variations in their glucose levels by changing colors - potentially replacing the need to routinely draw blood throughout the day.

The non-invasive technology, developed by Chemical and Biochemical Engineering professor Jin Zhang at The University of Western Ontario, uses extremely small nanoparticles embedded into the hydrogel lenses. These engineered nanoparticles react with glucose molecules found in tears, causing a chemical reaction that changes their color.

Osteoporosis Drug Lasofoxifene May "Fight" Several Diseases But Increases Risk of Blood Clots

Lasofoxifene is a part of a class of drugs known as nonsteroidal selective estrogen-receptor modulators (SERMs). It has already been shown to decrease the bone loss associated with osteoporosis, like other SERMs, including tamoxifen and raloxifene. But until now its effect on other health conditions commonly experienced by postmenopausal women was unknown.

The women who took lasofoxifene had an 81% lower risk of estrogen-receptor (ER) positive breast cancer, a 32% lower risk of heart-related events like heart attack, and a 36% lower risk of stroke. "This is the first SERM that reduces the risk of all of these conditions at once."

However, not all the results were positive. As with other SERMs, women taking lasofoxifene had double to nearly three times the risk of experiencing a serious blot clot of the deep veins.
