Head to head narcolepsy/hypersomnia study

At the sleep research meeting in San Antonio this year, there were signs of an impending pharmaceutical arms race in the realm of narcolepsy. The big fish in a small pond, Jazz Pharmaceuticals, was preparing to market its recently FDA-approved medication: Sunosi/solriamfetol. Startup Harmony Biosciences was close behind with pitolisant, already approved in Europe. On the horizon are experimental drugs designed to more precisely target the neuropeptide deficiency in people with classic narcolepsy type 1 Read more

Looking ahead to new opioid treatments

Stephanie Foster sees herself one day specializing in addiction psychiatry. When she started her MD/PhD studies at Emory, she sought out neuroscientist David Weinshenker to discuss research projects. She is now examining potential treatments for opiate addiction based on galanin, a neuropeptide found in the brain.

Weinshenker and his colleagues had already been studying galanin in relation to stimulants such as cocaine. Preliminary studies in animals indicate that activating galanin signals might reduce the rewarding effects of opiates, withdrawal symptoms, and relapse-like behavior.

“This was a whole new direction that looked promising,” Foster says. “But first, we have to work out the brain circuitry.”

Foster comes from a Native American background, and has a long-range plan to work in the Indian Health Service. The death rate of Native Americans from opiate overdoses is the highest of any American population group, according to the Centers for Disease Control and Prevention. She would like to establish a research lab in a region of the country where she could continue her addiction research and also work closely with Native communities.

Last year, Foster applied for and received an individual grant from the National Institute on Drug Abuse to support her work. Emory currently leads U.S. universities in the number of graduate students holding their own active grants from the National Institutes of Health. This reflects a multi-year effort to build instruction in critical parts of scientific life: planning and communicating about one’s work.

With opiate addiction, convincing others that the topic is worthwhile is not so difficult. Foster notes that few treatments are available for the early stages of opiate addiction. Long-lasting opiate substitutes/replacements such as methadone and buprenorphine are used once dependence has set in, and another medication, lofexidine, was recently approved for acute withdrawal symptoms.

“There isn’t really anything for people before they reach that stage,” Foster says. “Our idea is to look for an intervention that could be given earlier.” Read more

Nia Project: Helping victims of violence

Nadine Kaslow, PhD, Emory School of Medicine professor of psychiatry and behavioral sciences, founded in the early 1990s the Grady Nia Project for abused and suicidal African-American women. Named for the Kwanzaa term that means “purpose,” Nia serves countless numbers of abused women who come through Grady Memorial Hospital’s emergency department each year.

The program is funded by grants from the Centers for Disease Control and Prevention and the National Institute of Mental Health, and Kaslow serves as principal investigator. Kaslow also serves as chief psychologist at Grady Memorial Hospital and holds a joint appointment in the Departments of Psychology, Pediatrics and Emergency Medicine, and the Rollins School of Public Health.

Kaslow says the women in the Nia program, who either feel suicidal or have attempted suicide because of stress associated with violence, are victims of intimate partner violence and are usually black, minimally employed, with children and addicted to drugs and alcohol. Many are homeless.

Nia is staffed 24/7. Some staffers may make a trip to the emergency department in the middle of the night when a woman comes in with injuries or a story consistent with intimate partner violence or when she has attempted suicide. If a woman enrolls in the program, she will join approximately 50 to 75 other women who are going through it at any given time.
