New NIH Study to Look at House-to-House HIV Testing, Other Measures, to Reduce HIV Burden in Africa
A study in South Africa and Zambia is assessing whether house-to-house voluntary HIV testing and prompt treatment of HIV infection, along with other proven HIV prevention measures, can substantially reduce the number of new HIV infections across communities. The trial is funded primarily by the U.S. President's Emergency Plan for AIDS Relief (PEPFAR), administered by the Office of the Global AIDS Coordinator. “Through this new study, we aim to learn whether the treatment of HIV-infected individuals as a form of HIV prevention, an approach previously tested in roughly 1,800 heterosexual couples where one partner was infected, will be just as effective when implemented across an entire adult population,” said NIAID Director Anthony S. Fauci, MD. “The study also will tell us whether this method of delivering population-wide HIV treatment as prevention is feasible and cost-effective.” The trial is being conducted in South Africa and Zambia because the HIV prevalence in those countries is among the highest in the world. An estimated 12.5 percent of adults in Zambia and 17.3 percent of adults in South Africa are infected. The study team will measure the impact of the two HIV prevention packages by determining the number of new HIV infections among a representative sample of 52,500 adults drawn from the 21 study communities and followed for three years. The study is expected to end in 2019. Read more on AIDS.
Study: Better Awareness Likely Reason for Increase in ER Visits for Youth Concussions
Improved awareness of the signs and symptoms of traumatic brain injuries (TMI)—such as concussions—is likely the cause of a noticeable increase in TMI-related emergency department visits by children, according to a new study from doctors at the Cincinnati Children's Hospital Medical Center. The study appeared in the journal pediatrics. Visits for these types of injuries climbed about 92 percent from 2002 to 2011, while the overall severity of the injuries decreased and the hospitalization rate remained at around 10 percent. "We are doing a better job at educating ourselves and educating the public about concussion," said Dr. Holly Hanson, lead study author and an emergency medicine fellow. "People and doctors are recognizing sports-related concussions more. People are recognizing the signs and symptoms. People are more aware of the complications. So people are coming in more." According to the U.S. Centers for Disease Control and Prevent, each year TMI accounts for about 630,000 emergency department visits, 67,000 hospitalizations and 6,100 deaths in children and teens annually.

HHS Developing New Burn Treatments to Improve Disaster Response, Daily Care
Through its Biomedical Advanced Research and Development Authority (BARDA), the U.S. Department of Health and Human Services (HUD) is working to develop five new types of burn treatments for disaster response and daily emergency medical care. The thermal burn medical countermeasures—which could take the form of drugs, vaccines or medical products—will be for chemical, radiological or nuclear incidents. Developing new measures is critical, because with only 127 burn centers in the country, a mass casualty event could quickly overwhelm the public health response. “Sustainability of these medical countermeasures for thermal burns is critical for their availability when they are needed most,” said BARDA Director Robin Robinson, PhD. “Our repurposing and multi-purpose strategy facilitates development, ensures availability, and reduces overall costs for thermal burn medical countermeasures.” Read more on disasters.
