    The diagnostic and treatment possibilities made possible by the development and subsequent mainstreaming of clinical genomics services have the potential to profoundly change the experiences of families affected by rare genetic conditions. Understanding the potentials of genomic medicine requires that we consider the perspectives of those who engage with such services; there are substantial social implications involved. There are increasing calls to think more creatively, and draw on more participatory approaches, in evoking rich accounts of lived experience. In this article, we discuss our rationale for, and experiences of, using 'participatory-writing' to understand the diverse, variable and multilayered everyday lives of families and how these correspond with the emerging, rapidly changing and complex field of genomic medicine. Participatory-writing has many benefits as a method for social inquiry. Writing can be expressive and self-revelatory, providing insight into personal and sensitive topics. Writing together produces new conversations and relationships. Pieces written by participants have the potential to affect readers, evoking and enlivening research and prompting professional change. Working with a writing tutor, we organised a participatory-writing programme for families touched by genetic conditions. This involved a series of workshops with an emphasis on building confidence in expressing lived experience through experimenting with different writing techniques. Afterwards we arranged reflective interviews with participants. We drew on dialogical narrative analysis to engage with participants' written pieces, and highlight what everyday life is like for the people who live with, and care for, those with genetic conditions. The stories produced through our writing-groups unfold the implications of new genomic technologies, illuminating how genomics acts to (and likewise, fails to) reconfigure aspects of people's lives outside of the clinic, while simultaneously existing as a sociotechnical frame that can eclipse the wider contexts, challenges and liveliness of life with rare genetic conditions

    Experimental Study of a Hot Structure for a Reentry Vehicle

    Get PDF
    A large structural model of a reentry vehicle has been built incorporating design concepts applicable to a radiation-cooled vehicle. Thermal-stress alleviating features of the model are discussed. Environmental tests on the model include approximately 100 cycles of loading at room temperature and 33 cycles of combined loading and-heating up to temperatures of 1,6000 F. Measured temperatures are shown for typical parts of the model. Comparisons are made between experimental and calculated deflections and strains. The structure successfully survived the heating and loading environments

    Plasma Biomarkers for Detecting Hodgkin's Lymphoma in HIV Patients

    The lifespan of people with human immunodeficiency virus (HIV) infection has increased as a result of effective antiretroviral therapy, and the incidences of the AIDS-defining cancers, non-Hodgkin's lymphoma and Kaposi sarcoma, have declined. Even so, HIV-infected individuals are now at greater risk of other cancers, including Hodgkin's lymphoma (HL). To identify candidate biomarkers for the early detection of HL, we undertook an accurate mass and elution time tag proteomics analysis of individual plasma samples from either HIV-infected patients without HL (controls; n = 14) and from HIV-infected patient samples with HL (n = 22). This analysis identified 60 proteins that were statistically (p<0.05) altered and at least 1.5-fold different between the two groups. At least three of these proteins have previously been reported to be altered in the blood of HL patients that were not known to be HIV positive, suggesting that these markers may be broadly useful for detecting HL. Ingenuity Pathway Analysis software identified “inflammatory response” and “cancer” as the top two biological functions associated with these proteins. Overall, this study validated three plasma proteins as candidate biomarkers for detecting HL, and identified 57 novel candidate biomarkers that remain to be validated. The relationship of these novel candidate biomarkers with cancer and inflammation suggests that they are truly associated with HL and therefore may be useful for the early detection of this cancer in susceptible populations

    Caesarean section and risk of unexplained stillbirth in subsequent pregnancy

    Background Caesarean section is associated with an increased risk of disorders of placentation in subsequent pregnancies, but effects on the rate of antepartum stillbirth are unknown. We aimed to establish whether previous caesarean delivery is associated with an increased risk of antepartum stillbirth. Methods We linked pregnancy discharge data from the Scottish Morbidity Record (1980–98) and the Scottish Stillbirth and Infant Death Enquiry (1985–98). We estimated the relative risk of antepartum stillbirth in second pregnancies using time-to-event analyses. Findings For 120 633 singleton second births, there were 68 antepartum stillbirths in 17 754 women previously delivered by caesarean section (2–39 per 10 000 women per week) and 244 in 102879 women previously delivered vaginally (1·44; p&lt;0·001). Risk of unexplained stillbirth associated with previous caesarean delivery differed significantly with gestational age (p=0·04); the excess risk was apparent from 34 weeks (hazard ratio 2·23 [95% Cl 1·48–3·36]). Risk was not attenuated by adjustment for maternal characteristics or outcome of the first pregnancy (2·74 [1·74–4·30]). The absolute risk of unexplained stillbirth at or after 39 weeks' gestation was 1·1 per 1000 women who had had a previous caesarean section and 0·5 per 1000 in those who had not. The difference was due mostly to an excess of unexplained stillbirths among women previously delivered by caesarean section. Interpretation Delivery by caesarean section in the first pregnancy could increase the risk of unexplained stillbirth in the second. In women with one previous caesarean delivery, the risk of unexplained antepartum stillbirth at or after 39 weeks' gestation is about double the risk of stillbirth or neonatal death from intrapartum uterine rupture

    Importance of low-relief nursery habitat for reef fishes

    Get PDF
    Coastal restoration projects to mitigate environmental impacts have increased global demand for sand resources. Unfortunately, these resources are often extracted from sand/shell banks on the inner continental shelf, resulting in significant alteration or loss of low-relief reefs in coastal oceans. Experimental reefs (oyster shell, limestone rubble, composite) were deployed in the western Gulf of Mexico to assess their potential value as nurseries for newly settled reef fishes. Occurrence, abundance, and species richness of juvenile fishes were significantly higher on all three types of low-relief reefs compared with unconsolidated sediment. Moreover, reefs served as nursery habitat for a range of reef fish taxa (angelfishes, grunts, sea basses, snappers, and triggerfishes). Red snapper (Lutjanus campechanus) was the dominant species present on all experimental reefs (100% occurrence), and mean density of this species was markedly higher on each of the three low-relief reefs (\u3e40.0 individuals/reef) relative to comparable areas over unconsolidated sediment (0.2 individuals). Our results suggest creation or restoration of structurally complex habitat on the inner shelf has the potential to markedly increase early life survival and expedite the recovery of exploited reef fish populations, and therefore may represent a critical conservation tool for increasing recruitment and maintaining reef fish diversity

    Spiritual, religious, and existential concerns of children and young people with life-limiting and life-threatening conditions: A qualitative interview study

    Background:Despite being a core domain of palliative care, primary data on spiritual and existential concerns has rarely been collected among children with life-limiting and life-threatening conditions and their families. Existing evidence has tended to focus on the religious aspects among children with cancer.Aim:To identify the spiritual needs of children with life-limiting and life-threatening conditions.Design:Cross-sectional semi-structured, qualitative interview study with children, families and health and social care professionals. Verbatim transcripts were analysed using Framework analysisSetting/participants:Purposively sampled children with life-limiting and life-threatening conditions, their parents and siblings, health and social care professionals recruited from six hospitals and three children’s hospices in the UK, and commissioners of paediatric palliative care services recruited through networks and a national charity.Results:One hundred six participants were interviewed: 26 children (5–17 years), 53 family members (parents/carers of children 0–17 years and siblings (5–17 years)), 27 professionals (health and social care professionals and commissioners of paediatric palliative care). Themes included: living life to the fullest, meaning of life and leaving a legacy, uncertainty about the future, determination to survive, accepting or fighting the future and role of religion. Children as young as 5 years old identified needs or concerns in the spiritual domain of care.Conclusions:Addressing spiritual concerns is essential to providing child- and family-centred palliative care. Eliciting spiritual concerns may enable health and social care professionals to identify the things that can support and enhance a meaningful life and legacy for children and their families
