| Roles, responsibilities of patient navigators defined Posted: 23 Dec 2013 08:48 AM PST New research defines the roles and responsibilities of patient navigators. With the rapid growth of patient navigation, the paper seeks to develop a framework to describe similarities and differences across navigators and clarify their place in the health care system, leading to greater standardization of the profession.  |
| Getting excited helps with performance anxiety more than trying to calm down, study finds Posted: 23 Dec 2013 05:39 AM PST People who tell themselves to get excited rather than trying to relax can improve their performance during anxiety-inducing activities such as public speaking and math tests, according to a new study.  |
| Motor excitability predicts working memory Posted: 23 Dec 2013 05:38 AM PST Humans with a high motor excitability have a better working memory than humans with a low excitability. By measuring the motor excitability, conclusions can be drawn as to the general cortical excitability – as well as to cognitive performance. Working memory allows the temporary storage of information such as memorizing a phone number for a short period of time. Studies in animals have shown that working memory processes among others depend on the excitability of neurons in the prefrontal cortex.  |
| Life expectancy increases among treated HIV-positive individuals in US, Canada Posted: 18 Dec 2013 02:11 PM PST A 20-year-old HIV-positive adult on antiretroviral therapy in the US or Canada may be expected to live into their early 70s, a life expectancy approaching that of the general population.  |
| Researcher to grow human cells in space to test treatment for stroke Posted: 18 Dec 2013 11:36 AM PST A researcher believes that cells grown in the International Space Station (ISS) could help patients recover from a stroke, and that it may even be possible to generate human tissues and organs in space. He just needs a chance to demonstrate the possibility.  |
