BACKGROUND Whether community-associated methicillin-resistant Staphylococcus aureus (MRSA) genotypes (e.g., USA300) are a major cause of bloodstream infections (BSIs) and health care-associated infections has been poorly defined. METHODS Consecutive MRSA isolates recovered from patients with BSIs were prospectively collected at an urban public hospital.(More)
BACKGROUND A new generation of diagnostic tests, the interferon-gamma release assays (IGRAs), have been developed for the detection of latent tuberculosis infection (LTBI). Limited data are available on their use in HIV-infected persons. METHODS A cross-sectional study was carried out at 2 HIV clinics in Atlanta to assess the utility of two IGRA tests(More)
Antiretroviral treatment directed against HIV is highly effective, yet limited by drug resistance mutations. We hypothesized that CD8 T cells targeting drug-resistant HIV mutants are able to inhibit viral replication in the setting of a failing therapeutic regimen. We evaluated CD8 T-cell responses and mapped epitopes in HIV-infected patients by(More)
OBJECTIVE The goal of this study was to define more clearly the impact of community-acquired methicillin-resistant Staphylococcus aureus clones (eg, USA300 and USA400) on colonization and infection in infants in intensive care nurseries and potential modes of transmission of community-acquired methicillin-resistant S aureus clones. METHODS Prospective(More)
Excessive immune activation is a hallmark of chronic uncontrolled HIV infection. During the past years, growing evidence suggests that immune inhibitory signals also play an important role in progressive disease. However, the relationship between positive and negative immune signals on HIV-specific CD8 T cells has not been studied in detail so far in(More)
Developmental profiles of 14 different brain gangliosides were followed from the first day after hatching to the adult stage in two bird species representing different strategies of posthatch development: the nidifugous type (leaving the nest directly post-hatch, e.g. quail) and the nidicolous type (remaining for longer period in the nest, e.g. finch). In(More)
OBJECTIVE One focus in the medical care of HIV-infected patients today is cardiovascular risk reduction. Metabolic disturbances occur frequently in patients taking protease inhibitors (PI) and are a major risk factor for atherosclerosis. With few published head-to-head studies substance-specific differences concerning metabolic effects are insufficiently(More)
PURPOSE Germany is witnessing an increase in the number of new infections with human immunodeficiency virus (HIV). Enabling persons living with HIV (PLHIV) to adopt safer sex practices might contribute towards reducing the incidence of HIV infections. The aim of this study was to identify gaps in the sexual and reproductive health (SRH) services provided to(More)
