One of the tricky issues in studying in long COVID is: how widely do researchers cast their net? Initial reports acknowledged that people who were hospitalized and in intensive care may take a while to get back on their feet. But the number of people who had SARS-CoV-2 infections and were NOT hospitalized, yet experienced lingering symptoms, may be greater.
A recent report from the United Kingdom, published in PLOS Medicine, studied more than Read more
Efforts to produce a vaccine against HIV/AIDS have been sustained for more than a decade by a single, modest success: the RV144 clinical trial in Thailand, whose results were reported in 2009.
Now Emory, Harvard and Case Western Reserve scientists have identified a gene activity signature that may explain why the vaccine regimen in the RV144 study was protective in some individuals, while other HIV vaccine studies were not successful.
The researchers think that this signature, Read more
Encouraged by Emory’s success, Edmund Waller, MD, PhD, director of Emoryâ€™s Bone Marrow and Stem Cell Transplant Center says, “While 3,000 is a nice round number, it’s the middle of a growing and successful program. After 3,000 procedures, I know we all look forward to the future of this program.â€
A multi-patient organ swap, known as a paired donor exchange, can now save the lives of numerous people while matching each patient with the very best kidney for his or her blood profile.
Nearly 85,000 Americans are on a waiting list for a donated kidney â€“ nearly 3,000 in Georgia alone. The opportunity to quickly identify and match more organ donors and recipients is critical to saving more lives.
This month, Emoryâ€™s transplant team performed this type of exchange involving a total of six patients â€“ three donors and three recipients – from Texas, Colorado and Georgia.
In April, Howard Irving Scott, III, received a new kidney at Emory University Hospital. The kidney came to him as part of a six-person paired kidney transplant “chain,” in which three recipients and three donors were cross-matched. One of the participants was a friend of his, Casey Campbell. Although Scott did not receive Campbell’s kidney, her participation in the program made the “chain” transplant possible, saving Scott the possibility of waiting five years on a kidney.
Are you one of 50 million Americans who suffer from allergies? Allergies are the fifth-leading chronic disease in the U.S. among all ages, and the third most common chronic disease among children under age 18, according to the Asthma and Allergy Foundation of America.
Allergy is characterized by an overreaction of the human immune system to a foreign protein substance (â€œallergenâ€) that is eaten, breathed into the lungs, injected or touched. This immune overreaction can result in symptoms such as coughing, sneezing, itchy eyes, runny nose and scratchy throat. In severe cases it can also result in rashes, hives, lower blood pressure, difficulty breathing, asthma attacks, and even death.
In a series of new videos, Emory University pediatric allergist and immunologist Karen DeMuth, MD, discusses seasonal allergies, allergy triggers, coping methods, treatments and common allergy myths.
In another video series, DeMuth explores the link between asthma and allergies and the impact of air pollution on people with asthma.
DeMuth is an assistant professor of pediatrics in the Emory School of Medicine.Â She practices at the Emory-Children’s Center and Childrenâ€™s Healthcare of Atlanta.
One of the most important lessons from this past yearâ€™s pandemic, Fauci said, is the need to â€œconnect the dotsâ€ between seasonal and pandemic influenza and not view them as two separate phenomena.
â€œRather than trying to figure out one priority group over another,” Fauci said, “if we can get into a rhythm of getting most people vaccinated each year, we will have most of the population with some degree of immunity. We will get into a situation where we donâ€™t need to go from a seasonal approach to a crisis approach.
At a recent Emory global health seminar series, Kate Winskell showed how fiction penned by young Africans can help inform the response to HIV and AIDS. Since 1997, more than 145,000 young Africans have participated in scriptwriting contests as part of Scenarios from Africa HIV communication process.
The resulting archive of stories is a unique source of cross-cultural and longitudinal data on social representations of HIV and AIDS. The archive now spans 47 countries and a critical 12-year period in the history of the epidemic. Winskellâ€™s presentation analyzed the stories that were part of the 2005 Scenarios contest. Six African countries were represented.
The seed for Scenarios was planted more than a decade ago–before the rise of the Internetâ€”when Winskell, a public health educator, and her husband, Daniel Enger, were searching for innovative ways to reduce the spread of HIV/AIDS. The old ways of trying to stop the spread of the disease, focusing only on medical aspects of the epidemic or relying on educational materials that were not culturally adapted, were clearly limited.
At Emory’s fifth annual predictive health symposium â€œHuman Health: Molecules to Mankind,â€ Emory GYN/OB Sarah L. Berga, MD, discussed the state of childbirth in the United States and how maternal stress affects pregnant women and their fetuses.
Berga is McCord professor and chair of the Department of Gynecology and Obstetrics at Emory School of Medicine. Sadly, BergaÂ has seen maternal mortality rise steadily since the 1980s when she entered her medical residency. Georgia, she says, has the worse maternal mortality in the country. And the United States fares worse than many countries when it comes to maternal mortality.
Despite the unfortunate rise in maternal mortality of late, the good news is physicians have now started to pay more attention to the effect of stressâ€”both the physical and emotional kindâ€”on women and their fetuses. Recent research shows stress has the same negative effect on the body as do organic diseases, such as thyroid disease. In fact, too much stress reduces thyroxine levels by about 50 percent, says Berga. But because thereâ€™s no clinical recognition of this, tests are needed to determine if thyroxine levels are indeed insufficient.
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€
Peripheral artery disease affects millions of people in the United States. It’s basically hardening of the arteries (atherosclerosis) leading to problems with getting enough blood to the limbs. Symptoms of severe PAD include leg pain that doesn’t go away once exertion stops and wounds that heal slowly or not at all.
Lifestyle changes, medication and surgery can address some cases of PAD, but often the disease is not recognized until it has advanced considerably. At Emory, cardiologist Arshed Quyyumi has been exploring whether a patient’s own bone marrow cells can repair the arteries in his or her limbs.
You may have already heard that last month Emory held its fifth annual predictive health symposium â€œHuman Health: Molecules to Mankind.â€ Researchers, physicians, health care workers and members of the community from throughout the country met to learn about intriguing research and provocative commentary by health care experts.
One of those experts, Paul Wolpe,Â director of the Emory Center for Ethics,Â says health care has changed as more and more aspects of ordinary life or behaviors are being redefined as medical. For example, being drunk and disorderly has become alcoholism. Now, virtually all of life is being redefined in biological terms, he says. And that, says Wolpe, has led to an increase in health care costs. We have an enormous amount of new things that we are calling illness, and we expect our health care system to treat them, he says. â€œWe are creating a new category of disease called pre-symptomatic.â€
Every time scientists identify genetic risk factors for a human disease or a personality trait, it seems like more weight accumulates on the “nature” side of the grand balance between nature and nurture.
That’s why it’s important to remember how much prenatal and childhood experiences such as education, nutrition, environmental exposures and stress influence later development.
At the Emory/Georgia Tech Predictive Health Symposium in December, biologist Victor Corces outlined this concept using a particularly evocative example: bees. A queen bee and a worker bee share the same DNA, so the only thing that determines whether an insect will become the next queen is whether she consumes royal jelly.
