| CD4+ and CD8+ T lymphocyte counts, naive and memory/effector CD4+ T subpopulations, and the expression of CD38 on CD8+ T lymphocytes were evaluated in four groups: AIDS patients with tuberculosis (HIV/TB, n=14), HIV-1 infected patients (HIV, n=10), HIV-1 negative patients with tuberculosis (TB, n=20) and healthy controls (CTL, n=17). TB and HIV had fewer CD4+ T cells than CTL, with the lowest values observed in TB/HIV (p<0.001). No difference between groups was observed in the percentage of naive and memory/effector subpopulations in CD4+ T lymphocytes. TB (355 cells/mL) and HIV (517 cells/mL) had diverging effects on CD8+ T cell counts, with a marked depletion observed in HIV/TB (196 cells/mL). TB and HIV up-regulated CD38 expression on CD8+ T cells, a... |

| The objective of the study was to determine the effect of switching from an open (glass or semi-rigid plastic) infusion container to a closed, fully collapsible plastic infusion container (Viaflex®) on rate and time to onset of central lineassociated bloodstream infections (CLABSI). An open-label, prospective cohort, active healthcare-associated infection surveillance, sequential study was conducted in three intensive care units in Brazil. The CLABSI rate using open infusion containers was compared to the rate using a closed infusion container. Probability of acquiring CLABSI was assessed over time and compared between open and closed infusion container periods; three-day intervals were examined. A total of 1125 adult ICU patients were enrolled. CLABSI... |
