Transition to exhaustion: clues for cancer immunotherapy

Research on immune cells “exhausted” by chronic viral infection provides clues on how to refine cancer immunotherapy. The results were published Tuesday, Dec. 3 in Immunity. Scientists at Emory Vaccine Center, led by Rafi Ahmed, PhD, have learned about exhausted CD8 T cells, based on studying mice with chronic viral infections. In the presence of persistent virus or cancer, CD8 T cells lose much of their ability to fight disease, and display inhibitory checkpoint proteins Read more

Haiti

Cholera in the time of disaster

Alex Larsen couldn’t make it to the 2010 International Association of National Public Health Institutes (IANPHI) annual meeting. That’s because Larsen, Haiti’s minister of health, was attending to an outbreak of cholera in this impoverished republic.

Vibrio cholerae bacteria

Larsen was scheduled to speak on NPHIs’ role in disaster preparedness and response. Instead, Scott Dowell, director of the CDC’s division of global disease detection and emergency response, updated attendees about goings-on in Haiti since the massive January 12 earthquake and the recent outbreak of cholera.

The first two weeks after the tremblor and its immediate aftershocks, human and monetary resources were spent on search and rescue, including emergency trauma care, orthopedic surgery and amputations, says Dowell.

The number killed now stands at 200,000. The number displaced: 1.3 million. In addition to an initial lack of safe drinking water, hunger and poor sanitation, anecdotal accounts of diphtheria and tetanus outbreaks circulated. The headquarters housing the ministry of public health was itself devastated when it collapsed, killing most of the minister’s staff who had remained inside.

Since the earthquake, Dowell says the water supply has slowly improved with long-term sources coming on line. Efforts to better separate sewage and water are coming to fruition, too.

As far as the cholera outbreak is concerned, this chapter of Haiti’s public health challenges is just beginning thanks in part to Haiti having never before experienced a known cholera epidemic, says Dowell. That is, its population is most likely immunologically naïve to cholera, making people vulnerable to the bacteria’s devastating ways: severe diarrhea, vomiting, and abdominal pain culminating in overwhelming dehydration and even death.

Despite its troubles, Dowell says there’s long-term hope for Haiti. As found in other countries affected by cholera, an aggressive program to provide clean water and keep sewage and water separate, can eventually squelch the bacteria’s rampage—and in the meantime prevent other diseases from taking hold.

Medical volunteerism conference

A free weekend conference at Emory, beginning April 16 at 7 p.m., brings together health professionals and the general public to learn more about medical volunteerism. The event features keynote addresses, exhibits and brainstorming panel discussions on a variety of topics. Participants will be able to network with the general public, students, nurses and physicians representing all areas of health care.

The inaugural “International Conference on Medical Volunteerism” (ICMV) is hosted by the Emory School of Medicine and co-hosted by Morehouse School of Medicine, Mercer University School of Medicine, Medical College of Georgia, Philadelphia College of Osteopathic Medicine and the Medical University of South Carolina.

Conference organizers say they are offering a diverse array of events and presenters in hopes of inspiring more people to volunteer and create synergies among volunteer organizations and volunteers themselves.

“We want attendees to walk away with new, innovative ways and connections to help improve the overall health of the human race, particularly the underserved,” says Neil Shulman, MD, associate professor at Emory School of Medicine and chairman of the Conference Organizing Committee.

Nursing students give health care in the Dominican Republic

Recently, a group of Nell Hodgson Woodruff School of Nursing students traveled to the Dominican Republic for Alternative Spring Break.

Students team up to provide care in the Dominican Republic

Armed with food, medicine and clothing, the Emory students partnered with Dominican nursing and medical students to serve Haitians now living there after being displaced by the devastating Jan. 12 earthquake in Haiti.

Hunter Keys and Abby Weil were among the team of nursing students that journeyed to Santo Domingo, D.R. to provide health screenings and educational outreach. They also accompanied Dominican nursing students on home visits and elementary school visits.

Hunter and Abby blogged about their transformative experience.  On the second day of their travels, they wrote:

“…there is a huge need for ongoing care, including wound care, physical therapy, and mental health treatment. Dealing with these health issues on top of the terrible tragedy of losing loved ones, homes, and jobs is almost unimaginable. The process of healing will be long and difficult, both mentally and physically. One of the take home messages of the team was that while the great amount of aid pouring into Haiti directly after the earthquake is so useful and greatly needed, there will need to be a sustained effort to provide the services needed to facilitate this healing process.”
