    A rapid, low cost, accurate point-of-care (POC) device to detect influenza virus is needed for effective treatment and control of both seasonal and pandemic strains. We developed a single-use microfluidic chip that integrates solid phase extraction (SPE) and molecular amplification via a reverse transcription polymerase chain reaction (RT-PCR) to amplify influenza virus type A RNA. We demonstrated the ability of the chip to amplify influenza A RNA in human nasopharyngeal aspirate (NPA) and nasopharyngeal swab (NPS) specimens collected at two clinical sites from 2008–2010. The microfluidic test was dramatically more sensitive than two currently used rapid immunoassays and had high specificity that was essentially equivalent to the rapid assays and direct fluorescent antigen (DFA) testing. We report 96% (CI 89%,99%) sensitivity and 100% (CI 95%,100%) specificity compared to conventional (bench top) RT-PCR based on the testing of n = 146 specimens (positive predictive value = 100%(CI 94%,100%) and negative predictive value = 96%(CI 88%,98%)). These results compare well with DFA performed on samples taken during the same time period (98% (CI 91%,100%) sensitivity and 96%(CI 86%,99%) specificity compared to our gold standard testing). Rapid immunoassay tests on samples taken during the enrollment period were less reliable (49%(CI 38%,61%) sensitivity and 98%(CI 98%,100%) specificity). The microfluidic test extracted and amplified influenza A RNA directly from clinical specimens with viral loads down to 103 copies/ml in 3 h or less. The new test represents a major improvement over viral culture in terms of turn around time, over rapid immunoassay tests in terms of sensitivity, and over bench top RT-PCR and DFA in terms of ease of use and portability

    Observed emotional reactivity in response to frustration tasks in psychiatrically hospitalized youth with autism spectrum disorder

    Large emotional reactions (e.g. outbursts, tantrums) can be common and distressing in the lives of individuals with autism spectrum disorder and their families. Most previous research that has examined these types of emotional responses have used questionnaire data or focused only on young children. In addition, very little research has included individuals across a large range of intellectual and functional abilities or individuals with more severe emotional and/or behavioral difficulties. This study examined emotional reactions to frustrating tasks in 6-21-year-olds with autism spectrum disorder who were psychiatrically hospitalized due to emotional and/or behavioral difficulties. We describe change in the amount, intensity, duration, and range of emotional reactions that the participants displayed from a neutral activity to the frustrating tasks and then to a neutral recovery period. We also examined associations between characteristics of the participants and these emotional reactions. We found that younger children displayed more negative emotions across the neutral and frustrating tasks; however, age did not relate to how big their reactions to frustration were. Furthermore, we found that individuals with fewer adaptive skills (i.e. age-appropriate life skills) and minimally verbal individuals had bigger reactions and recovered less following the frustration tasks. The results highlight the importance of examining emotional reactions in individuals with lower verbal and adaptive abilities and for interventions to consider the connection between verbal and adaptive skills and emotional reactions

    A Call to Action for an Antiracist Clinical Science

    No full text
    Clinical psychological science is a field committed to reducing the negative impact of psychiatric illness through innovative research and psychological treatments. Unfortunately, the impact of racial injustices that pervade American society and permeate our academic institutions is felt not only by the individuals who work in our departments as faculty, staff, and students, but also by those who seek our services as mental health providers. Representing the collective work of numerous graduate students and postdoctoral trainees from multiple institutions, this call to action instantiates the need for prompt and consistent efforts towards dismantling institutionalized racism and inequity in clinical science. Specifically, we articulate the multiple roles our field plays in perpetuating racial oppression and outline concrete demands and recommendations for structural reform in the following key areas: (1) the mental health needs of Black, Indigenous, and People of Color (BIPOC) students, (2) clinical training and supervision, (3) curriculum and pedagogical approaches, (4) research and methods, and (5) the recruitment, retention, and success of graduate students and faculty

    Bluebell, short film and feminist film practice as research: Strategies for dissemination and peer review

    No full text
    This article seeks to reflect on my filmmaking practice through a discussion of my short film Bluebell (2003), situating the film within a theoretical context and providing a ‘route map’ of the practice research process. The film uses the cliché of ‘stranger rape’ to set up and upset audience expectations of rape narrative, challenging the construction of women as the victims rather than survivors of rape. Drawing on previous research on Angela Carter's reworking of Perrault's Little Red Riding Hood, and its reception by the feminist sisterhood, the article explores the opportunities and the dangers of feminist reappropriation of patriarchal narratives. The formal properties of the short film are examined as a potentially radical space for the emergent feminist filmmaker and strategies of dissemination and peer review are put forward. © 2007 Taylor & Francis Group, LLC

    Paternal exposure to Agent Orange and spina bifida: A meta-analysis

    No full text
    The objective of this study is to conduct a meta-analysis of published and unpublished studies that examine the association between Agent Orange (AO) exposure and the risk of spina bifida. Relevant studies were identified through a computerized literature search of Medline and Embase from 1966 to 2008; a review of the reference list of retrieved articles and conference proceedings; and by contacting researchers for unpublished studies. Both fixed-effects and random-effects models were used to pool the results of individual studies. The Cochrane Q test and index of heterogeneity (I(2)) were used to evaluate heterogeneity, and a funnel plot and Egger's test were used to evaluate publication bias. Seven studies, including two Vietnamese and five non-Vietnamese studies, involving 330 cases and 134,884 non-cases were included in the meta-analysis. The overall relative risk (RR) for spina bifida associated with paternal exposure to AO was 2.02 (95% confidence interval [CI]: 1.48-2.74), with no statistical evidence of heterogeneity across studies. Non-Vietnamese studies showed a slightly higher summary RR (RR = 2.22; 95% CI: 1.38-3.56) than Vietnamese studies (RR = 1.92 95% CI: 1.29-2.86). When analyzed separately, the overall association was statistically significant for the three case-control studies (Summary Odds Ratio = 2.25, 95% CI: 1.31-3.86) and the cross sectional study (RR = 1.97, 95% CI: 1.31-2.96), but not for the three cohort studies (RR: 2.11; 95% CI: 0.78-5.73). Paternal exposure to AO appears to be associated with a statistically increased risk of spina bifida
