The relationship between specific T cell subset alterations and mortality has not been well characterized in older adults. The specific aim was to determine whether specific T cell subsets are associated with an increased risk of death. We conducted a case-control study of T cell subsets (CD4+ and CD8+ T cells, and subsets of these cells defined by(More)
OBJECTIVES Experience Corps (EC) places older volunteers in public elementary schools in 20 cities across the country. The EC program in Baltimore is a health promotion intervention designed to improve the academic outcomes of children and increase older adult volunteer physical activity.

BACKGROUND The amount of cytomegalovirus (CMV) DNA in the blood (CMV load) may be a marker for detection of resistant CMV.METHODS. A total of 165 patients with AIDS and CMV retinitis had CMV load measurements (plasma and leukocyte) and cultures performed every 3 months; these measurements were correlated with CMV resistance to antiviral drugs and CMV(More)
BACKGROUND The exclusion of individuals with elevated acute phase proteins has been advocated in order to improve prevalence estimates of vitamin A deficiency in surveys, but it is unclear whether this will lead to sampling bias. The purpose of the study was to determine whether the exclusion of individuals with elevated acute phase proteins is associated(More)
BACKGROUND The cytomegalovirus (CMV) UL97 gene can be sequenced either from blood specimens directly amplified by polymerase chain reaction (PCR) or from culture isolates, to detect resistance to ganciclovir. METHODS A prospective epidemiological study was conducted in which paired specimens were routinely obtained for sequencing of the UL97 gene from(More)
