I3 Venture awards info

Emory is full of fledgling biomedical proto-companies. Some of them are actual corporations with employees, while others are ideas that need a push to get them to that point. Along with the companies highlighted by the Emory Biotech Consulting Club, Dean Sukhatme’s recent announcement of five I3 Venture research awards gives more examples of early stage research projects with commercial potential. This is the third round of the I3 awards; the first two were Wow! Read more

Take heart, Goldilocks -- and get more sleep

Sleeping too little or too much increases the risk of cardiovascular events and death in those with coronary artery disease, according to a new paper from Emory Clinical Cardiovascular Research Institute. Others have observed a similar U-shaped risk curve in the general population, with respect to sleep duration. The new study, published in American Journal of Cardiology, extends the finding to people who were being evaluated for coronary artery disease. Arshed Quyyumi, MD and colleagues analyzed Read more

Frailty: we know it when we can measure it

One of Lab Land’s regular features is a post exploring a biomedical term that seems to be appearing frequently in connection with Emory research. This month I’d like to focus on frailty, which has been an important concept in treating elderly patients for some time. (This piece in The Atlantic nudged me into it.) Assessing frailty is emerging as a way for surgeons to predict post-operative complications.

Several teams of researchers have been trying to develop a standardized way of measuring frailty to aid in weighing the risks and benefits of surgery. Frailty may seem like a subjective quality (echoing Supreme Court Justice Potter Stewart’s remarks on obscenity: “I know it when I see it”) but if frailty can be defined objectively, doctors and patients can use it to help in decision-making.

Frailty can be thought of as a decrease in physiological reserve or a decrease in the ability to recover from an infection or injury. Much of the credit for developing the concept of frailty should go to Linda Fried, now dean of Columbia’s school of public health. While at Johns Hopkins, her team developed the Hopkins Frailty Score: a composite based on recent weight loss, self-reported exhaustion, low daily activity levels, low grip strength and slow gait.
