New Flu Strains Prompt Review of Current Research, Call to Redouble Flu Fight
Released May 29, 2013 - Despite numerous medical advances over the past century, the flu—a seasonal rite of passage for many around the world—still remains deadly and dangerous. In April of this year, a new flu strain known as H7N9, thought to have the potential to cause a pandemic, emerged in China. This novel strain’s high mortality rate has led the Centers for Disease Control and Prevention to issue predictions of hospitalizations, deaths, and economic impacts several times higher than those caused by the typical seasonal flu. In light of this and other information researchers have published a comprehensive overview of current flu research and efforts to combat this potentially lethal disease, including global surveillance to track the flu and vaccines and antiviral drugs currently in use. They also issue a call to improve efforts to fight the flu, including improving efforts to educate the public about the flu.

Nearly Half of Veterans With Blast Concussions Might Have Hormone Deficiencies
Released April 22, 2013 - Up to 20 percent of veterans returning from Afghanistan and Iraq have experienced at least one blast concussion. A new study finds about 42% of screened veterans with blast injuries have irregular hormone levels indicative of hypopituitarism, the decreased (hypo) secretion of one or more of the eight hormones normally produced by the pituitary gland at the base of the brain. Many conditions associated with hypopituitarism mimic other common problems that veterans can suffer, including post-traumatic stress disorder (PTSD) and depression.
