The death rates of children with HIV have decreased ninefold since doctors started prescribing cocktails of antiretroviral drugs in the mid-1990s, concludes a large-scale study of the long-term outcomes of children and adolescents with HIV in the United States. In spite of this improvement, however, young people with HIV continue to die at 30 times the rate of youth of similar age who do not have HIV, found researchers from the National Institutes of Health and other institutions.
A new study involving data from more than 20,000 individuals has uncovered several DNA sequences linked to impaired pulmonary function. The research, an analysis that combined the results of several smaller studies, provides insight into the mechanisms involved in reaching full lung capacity. The findings may ultimately lead to better understanding of lung function and diseases like asthma and chronic obstructive pulmonary disease (COPD), the fourth leading cause of death in the United States.
