Study provides new insight into human cognitive function and risk for neurological diseases

Short snippets of DNA found in human brain tissue provide new insight into human cognitive function and risk for developing certain neurological diseases, according to researchers from the Departments of Psychiatry and Neuroscience at Mount Sinai School of Medicine. The findings are published in the November 20th issue of PLoS Biology.

Sleep deprivation could affect academic performance of college students

As fall semesters wind down at the country's colleges and universities, students will be pulling all-night study sessions to prepare for final exams. Ironically, the loss of sleep during these all-nighters could actually work against them performing well, says a Harris Health System sleep specialist.

No differences between computer-navigated and traditional TKA related to knee function, pain

For many years, the use of computer-assisted navigation has been touted as improving the positioning, sizing and alignment of replacement knee joints, resulting in greater durability of joints and overall improvement in patient movement. However, new research published in the Journal of Bone and Joint Surgery (JBJS) found no difference in knee function, alignment or durability/survivorship between joints positioned and completed with the help of computer navigation, and those replaced with conventional total knee arthroplasty (TKA) procedures.

Viewpoints: Protecting us from counterfeit medicines; Governors making excuses on insurance exchanges?; Simpson-Bowles and the health law

HHS has made it clear that after federally operated exchanges are up and running, states may eventually take over operations. This seems like wasted effort.
