Thoracic endografts used successfully to remove tumors invading the aorta
Tumors have the potential to grow locally and invade neighboring organs. Some chest tumors may invade one of the great vessels of the body, the aorta. Surgical removal of these tumors is very challenging and necessitates the support of a heart-lung machine. Therefore there is an increased risk of complication and death. In a small series of patients, placing a stent within the aorta facilitated the subsequent removal of tumor and eliminated the need for heart-lung bypass. A report of these results is presented by Stéphane Collaud, MD, MSc, at the Emerging Technology and Techniques Forum of the 93rd AATS Annual Meeting in Minneapolis on May 8, 2013.

Neuroscientists put heads together at national brainstorming session
(Medical Xpress)—This week over 150 neuroscientists were invited to meet in Arlington, Virginia to discuss the finer points of President Obama's recently announced BRAIN Initative. Rather than discuss funding particulars, each participant was given the chance to broadly declare what they thought needed to be done in neuroscience. At least 75 of the participants initially responded to a request for a short white paper outlining the major obstacles currently impeding neuroscience research. A live webcast of some of the key talks was available, although many of the smaller workshops were held in private. Fortunately, updates regarding the content discussed at these workshops was posted live to twitter under the handle @openconnectome. This precipitated lively discussion, primarily under the hashtags #nsfBRAINmtg or #braini, and provided a way for a larger audience to be involved.
