Treatment for Positive Urine Cultures in Hospitalized Adults: A Survey of Prevalence and Risk Factors in 3 Medical Centers.

Background: Antibiotic treatment for asymptomatic bacteriuria (ASB) is prevalent but often contrary to published guidelines.

Objective: To evaluate risk factors for treatment of ASB.

Design: Retrospective observational study.

Acute Human Immunodeficiency Virus (HIV) Syndrome After Nonadherence to Antiretroviral Therapy in a Patient With Chronic HIV Infection: A Case Report.

We report a rare case of acute human immunodeficiency virus (HIV) syndrome in a patient with chronic HIV infection with acute illness indistinguishable from acute retroviral syndrome. The patient presented with an acute febrile mononucleosis-like illness after increasing nonadherence to antiretroviral therapy. A marked increase in HIV RNA level of 1 220 000 copies/mL from less than 20 copies/mL occurred within 3 weeks.

Functional enhancement of neuronal cell behaviors and differentiation by elastin-mimetic recombinant protein presenting Arg-Gly-Asp peptides.

Background: Integrin-mediated interaction of neuronal cells with extracellular matrix (ECM) is important for the control of cell adhesion, morphology, motility, and differentiation in both in vitro and in vivo systems. Arg-Gly-Asp (RGD) sequence is one of the most potent integrin-binding ligand found in many native ECM proteins. An elastin-mimetic recombinant protein, TGPG[VGRGD(VGVPG)6]20WPC, referred to as [RGD-V6]20, contains multiple RGD motifs to bind cell-surface integrins.
