At a time when COVID-19 appears to be receding in much of Georgia, it’s worth revisiting the start of the pandemic in early 2020. Emory virologist Anne Piantadosi and colleagues have a paper in Viral Evolution on the earliest SARS-CoV-2 genetic sequences detected in Georgia.
Analyzing relationships between those virus sequences and samples from other states and countries can give us an idea about where the first COVID-19 infections in Georgia came from. We can draw Read more
Drug abuse researchers are using the social media site Reddit as a window into the experiences of people living with opioid addiction.
Abeed Sarker in Emory's Department of Biomedical Informatics has a paper in Clinical Toxicology focusing on the phenomenon of “precipitated withdrawal,” in collaboration with emergency medicine specialists from Penn, Rutgers and Mt Sinai.
Precipitated withdrawal is a more intense form of withdrawal that can occur when someone who was using opioids starts medication-assisted treatment Read more
The big news out of CROI (Conference on Retroviruses and Opportunistic Infections) was a report of a third person being cured of HIV infection, this time using umbilical cord blood for a hematopoetic stem cell transplant. Emory’s Carlos del Rio gave a nice overview of the achievement for NPR this morning.
As del Rio explains, the field of HIV cure research took off over the last decade after Timothy Brown, known as “the Berlin patient,” Read more
The idea of your child having an eye removed is shocking, an extremely difficult thing for a parent to cope with, says Baker Hubbard, MD, Thomas M. Aaberg Professor of Ophthalmology, and a pediatric ocular oncologist. Actually, says Hubbard, most children who lose an eye adapt very well and enjoy essentially normal lives.

Retinoblastoma is cancer that forms in the tissues of the retina (the light-sensitive layers of nerve tissue at the back of the eye). Retinoblastoma usually occurs in children younger than age five. It may be hereditary or nonhereditary (sporadic), and is caused by mutations in genes.
To six-year-old Emilia McKibbin, having a prosthetic eye is no big deal. She knows to protect itâ€”wearing her glasses for school and playtime, donning a scuba mask at the beachâ€”but it doesnâ€™t limit her choices.
Following her interests, Emilia has earned a gold belt in karate. Sheâ€™s learning gymnastics. She swims. She loves to romp with Daisy, her black cocker spaniel. And while most people donâ€™t even notice that one of this little girlâ€™s shining dark-brown eyes is different from the other, Emilia shares her story with a few. â€œI tell my teachers and my friends that I have a special eye,â€ she says.
When Cynthia Anderson, MD, prepares her patients for stereotactic radiosurgery she emphasizes three things: the surgery is fast, friendly and focused. Initially used to treat the part of the brain associated with brain tumors, stereotactic radiosurgery has gained currency as a treatment for various types of cancer. This type of surgery uses x-ray beams instead of scalpels to eliminate tumors of the liver, lung and spine.
“It’s fast because the actual radiation treatment itself is very short,” says Anderson, a radiation oncologist at the Winship Cancer Institute of Emory University. “It’s friendly because it’s all done as an outpatient. And it’s focused because these targeted radiation beams get the maximum dose of radiation to a tumor and give the most minimal dose of radiation to the critical organs that surround the tumor.”
Vision loss can affect oneâ€™s daily function and quality of life (QOL), but few research studies have actually looked at the impact of visual impairments on childrenâ€™s quality of life.
An Emory project aims to develop an instrument that will measure the effect of vision loss on the quality of life of children age 8 to 18.

Devn Cornish, MD, professor and vice chair, Department of Pediatrics, Emory University School of Medicine; Andy Lovas, grand recorder, Knights Templar Eye Foundation; Sheila Angeles-Han, MD, MSc, assistant professor, Pediatric Rheumatology and Immunology, Emory University School of Medicine; Larry Vogler, MD, division chief, Pediatric Rheumatology and Immunology, Emory University School of Medicine; and Tim Taylor, director of marketing, Knights Templar Eye Foundation
The project is being led by Emory pediatric rheumatologist Sheila Angeles-Han, MD, MSc. Han recently received a $40,000 grant from the Knights Templar Eye Foundation to augment her work in this area. She is collaborating with pediatric ophthalmologists at the Emory Eye Center.
Currently, there are no validated questionnaires or tools to determine how children in these age groups cope with their visual impairments and the impact of vision loss on their daily lives. This knowledge can enhance physiciansâ€™ understanding of diseases that affect vision.
Researchers at Emory studying lung transplantation have identified a marker of inflammation that may help predict primary graft dysfunction (PGD), an often fatal complication following a lung transplant.
â€œDespite major advances in surgical techniques and clinical management, serious lung transplant complications are common and often untreatable,â€ Pelaez says. â€œPGD is a severe lung injury appearing just a few days after transplantation. Unfortunately, predicting which lung transplant recipients go on to develop PGD has been so far unsuccessful. Therefore, our research has been directed towards identifying predictive markers in the donor lungs prior to transplantation.â€

A first at Emory and in Georgia, the DEU is based on the model implemented by the University of Portland School of Nursing and its clinical partners in the early 2000s.
Kelly Brewer, who holds a joint appointment with the School of Nursing and Emory Healthcare as DEU coordinator, says, â€œOur DEU initiative relies on these concepts and the skills of nurses and faculty to help students transition into the real world of nursing. Itâ€™s a win-win situation for both sets of professionals since faculty and clinical nurses are in short supply because of the nursing shortage.
â€œBoth of our hospitals are committed to making students feel that they are part of the unit so theyâ€™ll want to work there after they graduate,â€ she adds. â€œThey will already have a sense of what Emoryâ€™s health care system is about, and their transition into the real world of health care will be less stressful.â€
Little is known about the exposure of infants to pesticides, despite their vulnerability and evidence of widespread dietary exposure among older children and adults. A study led by Emory Rollins School of Public Health researchers P. Barry Ryan, PhD, and Anne Riederer, ScD, seeks to improve methods for measuring pesticides in breast milk and infant formula.
â€œWe really donâ€™t know about how babies are exposed to pesticides in their everyday life,â€ says Riederer, assistant research professor, Department of Environmental and Occupational Health. â€œThere are very few published studies on this topic, and weâ€™d like to be one of the groups that actually publishes an analytical method that can be used by researchers in any country to be able to detect these different types of pesticides in breast milk.â€
Although the breast milk method will be pilot tested on samples collected from a birth cohort in Thailand, it will have broad applications for the U.S. population. Insight Pest Control Wilmington says that because these pesticides are widely distributed in the food supply, all U.S. infants are potentially exposed.
Javed Butler, MD, MPH, director of heart failure research at Emory Healthcare and associate professor of medicine at Emory University School of Medicine, says heart failure is any condition in which the heart is unable to pump enough blood for the metabolic needs of the body, but that does not mean that the heart is not pumping or the heart has stopped working.
Heart disease is not a disease but a syndrome, so a whole family of different diseases can precede this condition. Diabetes, obesity, heart valve problems, lung disease, heart attack and irregular heartbeats are only some factors that can cause heart failure. “Pinning down the roots of heart failure can be confusing,” says Butler, who serves as deputy chief science advisor for the American Heart Association. “Unlike some heart problems, heart failure is not one disease. It has a few common causes, and a few less common, even rare, causes.”
Finding new ways to identify people at risk for developing heart failureâ€”before damage is doneâ€”is his raison d’etre and primary research focus, according to Emory Medicine magazine.
Macular degeneration is the leading cause of sight impairment and blindness in older people. The macula, in the center of the retina, is the portion of the eye that allows for the perception of fine detail. AMD gradually destroys a personâ€™s central vision, ultimately preventing reading, driving, and seeing objects clearly
In a recent article of Emory Magazine, Ono, an ocular immunologist, says, â€œIf a person with AMD looks at graph paper, some of the lines will be wavy instead of straight. Certain parts of the image are no longer being transferred to the brain.â€
The palliative care program at Emory University is working to improve quality of life and wellness by addressing the physical, psychological, ethical, spiritual and social needs of patients with serious, life-threatening or progressive chronic illnesses, and provides support to their families and caregivers.

Often mistakenly confused with hospice care, palliative care is appropriately provided to patients in any stage of serious illness – whereas hospice care is primarily used for those approaching the end stage of life, says Tammie Quest, MD, interim director of the Emory Center for Palliative Care.
A typical palliative care “team” consists of physicians, nurses, social workers, chaplains, mental health professionals, therapists and pharmacists, assisting patients through a wide array of illnesses, including stroke, heart and lung disease, cancer and HIV.
The palliative care teams work closely with primary physicians to control pain, relieve symptoms of illnesses – such as nausea, fatigue and depression. Teams help provide counseling in making difficult medical decisions and provide emotional and spiritual support, coordinate home care referrals and assist with identifying future care needs.
For adult organ transplant recipients, juggling a lifetime regimen of immunosuppressant drugs is difficult enough, but for children it presents an even greater challenge.Â These drugs, which also can have toxic side effects, must strike a delicate balance between preventing organ rejection and protecting from infections.
But childrenâ€™s immune systems are still â€œlearningâ€ what distinguishes them from the world around them, and children are constantly developing and changing, both physically and emotionally. This puts them at greater risk for complications either through inappropriate medication or failure to take these drugs properly.
The ARRA-funded project will not only help determine which medications children should take, but also will give them the support to care for their transplanted organs.Â The Emory scientists are studying new biological monitoring technologies that can identify unique ways to determine exactly how much medication a child really needs. These studies are being combined with a novel transition care clinic specializing in helping children cope with their illness and assuming responsibility for their care.
â€œThis award indicates exceptional insight by the NIAID into the critical link between a childâ€™s physical well-being and their emotional maturity,â€ says Kirk. â€œIt will accelerate progress in this vital area of research for a very deserving subset of chronically ill children.â€
