Social-cognitive predictors of intention to vaccinate against the human papillomavirus in college-age women.

This study examined social-cognitive predictors of college-age women's intentions to obtain the human papillomavirus (HPV) vaccine using the Health Belief Model (HBM) and Theory of Planned Behavior (TBP) as theoretical guides. Questionnaire data were collected from 143 women at a Midwestern university. Among the HBM variables, perceived susceptibility to HPV, perceived benefits of the vaccine, and self-efficacy to obtain the vaccine were significant predictors. Among the TPB variables, positive attitudes toward the vaccine and beliefs that important others would support vaccination predicted intentions. A model with all HBM and TPB variables explained nearly 60% of the variance in intentions. Comparison of the theories suggests that the TPB is a better predictor of intentions than the HBM. Results suggest that targeting personal beliefs about the vaccine, and increasing acceptance for the vaccine among social network members, may increase vaccination intentions among college-age women.

A single slide multiplex assay for the evaluation of classical Hodgkin lymphoma.

Classical Hodgkin lymphoma can be diagnosed with confidence in the majority of cases, but there is a significant subset that remains a diagnostic challenge. The authors have investigated the utility of a novel hyperplexing technology, MultiOmyx™, which may be applied to stain with >60 antibodies on single tissue sections from formalin-fixed paraffin-embedded tissue as an aid to the diagnosis of classical Hodgkin lymphoma. The multiplexing protocol included CD30, CD15, PAX-5, CD20, CD79a, CD45, BOB.1, OCT-2, and CD3 antibodies. The technology showed a high degree of sensitivity, specificity, and precision. Comparison studies with routine hematoxylin and eosin and immunohistochemical assessment of hematopathology cases in which classical Hodgkin lymphoma was included in the differential diagnosis showed concordance in 54 of 56 cases, with the 2 discordant cases illustrating the potential of this multiplexed immunofluorescence technology to improve on traditional immunohistochemistry for classical Hodgkin lymphoma diagnosis. This technology is practical for routine diagnosis and may be particularly useful in cases in which the sample size is limited, few Hodgkin-like cells are present, or in CD30-positive lymphoma cases with difficult morphology. MultiOmyx may potentially benefit other areas of research and diagnostic pathology.
