Micronutrients: food for thought

Conrad Cole, MD, MPH

Physicians and researchers are seeing a resurgence of micronutrient deficiencies in certain high-risk populations of children. But what exactly does that mean to those children—right now and in the future?

For children who don’t get enough micronutrients it means life-long problems, including decreased neurodevelopment and diminished cognitive abilities.

“Micronutrients are nutrients that are needed by the body in small quantities and are important for development, growth and sustaining life,” says Conrad Cole, MD, MPH, assistant professor of pediatrics in the Division of Pediatric Gastroenterology and Nutrition in Emory School of Medicine. “That’s why they’re called micronutrients, and the ones we commonly think about are iron, vitamin D, calcium and zinc because they all have significant importance.”

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.

Community groups play key role in increasing HIV research participation

Paula Frew, PhD, MPH

Although African Americans make up a significant share of HIV cases in the U.S., they are underrepresented in HIV clinical trials. New research shows that promotion of HIV clinical trials and participation by African Americans can be increased by coalitions that link community organizations to clinical-research institutions.

“Community organizations already have built trusting relationships in their communities,” says Paula Frew, PhD, assistant professor of medicine at Emory School of Medicine. “If HIV/AIDS prevention and HIV clinical research become part of the agendas of these organizations, they can become ideal allies for increasing participation by community members who are at risk for disease.”

Frew was lead investigator in a study published recently in the Journal Prevention Science. She is director of health communications & applied research at the Hope Clinic of the Emory Vaccine Center and an investigator in the Emory Center for AIDS Research (CFAR).

Raising awareness for sickle cell disease

September is National Sickle Cell Awareness Month, and when it comes to assessing and treating sickle cell disease, there is no other place in the world like the Georgia Comprehensive Sickle Cell Center at Grady Memorial Hospital.

Led by James R. Eckman, MD, pioneering medical director and professor of medicine at Emory School of Medicine, the Center is the world’s first 24-hour comprehensive primary care clinic for patients with sickle cell syndromes. It is comprised of a multidisciplinary team with the a mission to educate and provide preventative and comprehensive primary care, while responding to sickle cell emergencies quickly and efficiently.

Millions of people worldwide suffer from the affects of sickle cell anemia – especially those of African, Mediterranean and Indian descent. According to CDC, more than 70,000 people in the United States have sickle cell disease, mostly African Americans. Each year more than 1,000 babies are born with sickle cell disease.

The inherited disorder affects the blood’s hemoglobin, which produces stiff, misshapen red blood cells that deliver less oxygen and can disrupt blood flow, resulting in joint and organ damage and potential clots and strokes. The sickling of red blood cells is aggravated by infections, extreme hot or cold temperatures, poor oxygen intake, not drinking enough fluids and stress.
