BACKGROUND Studies in the United States show that rural persons with HIV are more likely than their urban counterparts to be diagnosed at a late stage of infection, suggesting missed opportunities for HIV testing in rural areas. To inform discussion of HIV testing policies in rural areas, we generated nationally representative, population-based estimates of(More)
Salmonellae are gram-negative bacteria that cause gastroenteritis and enteric fever. Salmonella virulence requires the coordinated expression of complex arrays of virulence factors that allow the bacterium to evade the host's immune system. All Salmonella serotypes share the ability to invade the host by inducing their own uptake into cells of the(More)
The Salmonella enterica serovar Typhimurium type III secretion system (TTSS) encoded in Salmonella pathogenicity island 2 (SPI-2) promotes replication within host cells and systemic infection of mice. The SPI-2 TTSS is expressed following Salmonella internalization into host cells and translocates effectors across the membrane of the Salmonella-containing(More)
BACKGROUND Retention in care is important for all HIV-infected persons and is strongly associated with initiation of antiretroviral therapy and viral suppression. However, it is unclear how retention in care and age interact to affect viral suppression. We evaluated whether the association between retention and viral suppression differed by age at entry(More)
Rapid and accurate health literacy screening tools could assist interventions to improve care in the HIV clinic setting. Prior studies described brief screening questions for identification of persons with low health literacy, but the performance of these questions in HIV clinics is unknown. We examined the accuracy of provider perception and previously(More)
Contemporary Bartonella quintana infections have emerged in diverse regions of the world, predominantly involving socially disadvantaged persons. Available data suggest that the human body louse Pediculus humanus is the vector for transmission of B. quintana. Descriptions of the clinical manifestations associated with contemporary B. quintana infections(More)
Administrative code data (ACD), such as International Classifications of Diseases, Ninth Revision, Clinical Modification codes, are widely used in surveillance and public reporting programs that seek to identify healthcare-associated infections (HAIs); however, little is known about their accuracy. This systematic review summarizes evidence for the accuracy(More)
CONTEXT Rural persons with human immunodeficiency virus (HIV) face many barriers to care, but little is known about rural-urban variation in HIV outcomes. OBJECTIVE To determine the association between rural residence and HIV outcomes. DESIGN, SETTING, AND PATIENTS Retrospective cohort study of mortality among persons initiating HIV care in Veterans(More)
Patient electronic personal health record (PHR) use has been associated with improved patient outcomes in diabetes and depression care. Little is known about the effect of PHR use on HIV care processes and outcomes. We evaluated whether there was an association between patient PHR use and antiretroviral adherence. Data came from the Veterans Aging Cohort(More)
