The number of cardiovascular drugs in the research pipeline has declined across all phases of development in the last 20 years even as cardiovascular disease has become the number one cause of death world-wide, according to research published today in JACC: Basic to Translational Science.

While the development and use of new prescription drugs have been associated with significant reduction in cardiovascular mortality over the past two decades, cardiovascular disease is still the leading cause of death in the developing world and accounts for 1 in 3 deaths in the United States. There has been growing concern over the decline in the development of new therapies.

NEW YORK, NY (August 29, 2016)-- New findings suggest that most Americans with depression receive no treatment, while raising the possibility that overtreatment of depression is also widespread. Less than a third of American adults who screened positive for depression received treatment for their symptoms, whereas over two-thirds of adults receiving treatment for depression did not report symptoms of depression or serious psychological distress, according to a study from Columbia University Medical Center (CUMC) and the University of Pennsylvania.

The study also found that among those who are treated for depression, less than half of those with severe psychological distress are seen by a mental health specialist.

Even if we find it difficult to calculate complicated probabilities on the spot, our brains constantly carry out these sorts of computations without our awareness -- and they're remarkably good at it.

Dogs have the ability to distinguish vocabulary words and the intonation of human speech through brain regions similar to those that humans use, a new study reports. Attila Andics et al. note that vocabulary learning "does not appear to be a uniquely human capacity that follows from the emergence of language, but rather a more ancient function that can be exploited to link arbitrary sound sequences to meanings." Words are the basic building blocks of human languages, but they are hardly ever found in nonhuman vocal communications. Intonation is another way that information is conveyed through speech, where, for example, praises tend to be conveyed with higher and more varying pitch. Humans understand speech through both vocabulary and intonation.

New research presented at this year's World Congress of Anaesthesiologists (WCA) in Hong Kong (Aug. 28 - Sept. 2) shows that allowing children to use iPads to distract them before surgery requiring general anaesthesia is as effective at lowering their anxiety as conventional sedatives. Furthermore, parental satisfaction and quality of anaesthesia induction was higher in children using iPads. The study is by Dr Dominique Chassard, EPICIME, Hopital Mere Enfant, Hospices Civils de Lyon, Bron, France, and colleagues.

HOUSTON-(Aug. 23, 2016)-Researchers at Houston Methodist have developed an artificial intelligence (AI) software that reliably interprets mammograms, assisting doctors with a quick and accurate prediction of breast cancer risk. According to a new study published in Cancer (early online Aug. 29), the computer software intuitively translates patient charts into diagnostic information at 30 times human speed and with 99 percent accuracy.
