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
Akin to a fibrous, thick rubber band made of collagen, the ACL runs through the center of the knee and connects the femur to the tibia, allowing the knee to bend and flexâ€”but not too far. When it tears, the knee can become destabilized. So, for anyone who wants to continue to play sports, surgery is required.
Once a narrow subspecialty of orthopaedics with a focus on professional athletes, the field of sports medicine has exploded in the last decade. The evolution of ACL surgery is just one of several advances in the treatment of athletes and their injuries that have started to serve not only the pros who make a living from their skills, but also the weekend warrior.
This may include individuals who get hurt in the heat of a pick-up game, the neighborhood league player with tennis elbow, the college runner who pulls a tendon, or the high school football player with a possible concussion. Read more
Orthopaedics is a constantly evolving subspecialty where medical technology and research drives the development of new products used for reconstruction of body parts, specifically for hip and knee replacements.
Emory has been on the forefront of investigating and using three materials for these replacements: ceramic on ceramic surfaces, metal on metal surfaces, or highly cross-linked polyethylene. These newer biomaterials can reduce wear rates by over 99 percent compared to previous materials, thus enhancing the life of the new hip or knee.
Adult reconstruction or hip and knee arthritis surgery delivers quality outcomes that make a dramatic improvement in a patientâ€™s quality of life. At the first post-operative visit, patients are more comfortable, have less pain and are even more functional than before their surgery.
Orthopeadic surgeon James R. Roberson, MD, chairman, Department of Orthopaedics in Emory School of Medicine, and professor of orthopaedic surgery specializes in adult reconstructive surgery of the hip and knee.
Roberson has been involved in clinical research for more than 20 years to solve difficult problems of the arthritic hip and knee. He pioneered a minimally invasive surgery technique for knee replacement that allows him to use smaller incisions in certain patients who have uncomplicated conditions.
