Adults with hypertension who are age 75 years and older, including those who are frail and with poor overall health, could benefit from lowering their blood pressure below current medical guidelines. The multi-institutional investigation was published online in The Journal of the American Medical Association (JAMA) and presented at the American Geriatrics Society Annual Scientific Meeting on May 19. The findings could have broad health implications for older Americans, 75 percent of whom have high blood pressure.
Coprophagia, eating one’s feces, is common in animals but rarely seen in humans. Mayo Clinic researchers reviewed the cases of a dozen adult patients diagnosed with coprophagia over the past 20 years and found that the behavior is associated with a wide range of neuropsychiatric disorders, particularly neurodegenerative dementias. The findings are published in the Journal of Neurology.

A drug commonly used to treat pain, epilepsy, anxiety and other brain health disorders may be associated with an increased risk of major birth defects, according to a study published in the May 18, 2016, online issue of Neurology®, the medical journal of the American Academy of Neurology.
A 24-hour rhythm of cellular detoxification in flies and mammals is coordinated by a neuropeptide that also drives feeding in both organisms. Many detoxification genes are expressed with a circadian rhythm in the mouse liver and in the fruitfly equivalent called the fat body. This work could eventually have implications for chronotherapy -- the study of the timing of when best to take medications.
