A Feasibility Study of Quantifying Longitudinal Brain Changes in Herpes Simplex Virus (HSV) Encephalitis Using Magnetic Resonance Imaging (MRI) and Stereology.

OBJECTIVES: To assess whether it is feasible to quantify acute change in temporal lobe volume and total oedema volumes in herpes simplex virus (HSV) encephalitis as a preliminary to a trial of corticosteroid therapy. METHODS: The study analysed serially acquired magnetic resonance images (MRI), of patients with acute HSV encephalitis who had neuroimaging repeated within four weeks of the first scan. We performed volumetric measurements of the left and right temporal lobes and of cerebral oedema visible on T2 weighted Fluid Attenuated Inversion Recovery (FLAIR) images using stereology in conjunction with point counting. RESULTS: Temporal lobe volumes increased on average by 1.6% (standard deviation (SD 11%) in five patients who had not received corticosteroid therapy and decreased in two patients who had received corticosteroids by 8.5%. FLAIR hyperintensity volumes increased by 9% in patients not receiving treatment with corticosteroids and decreased by 29% in the two patients that had received corticosteroids. CONCLUSIONS: This study has shown it is feasible to quantify acute change in temporal lobe and total oedema volumes in HSV encephalitis and suggests a potential resolution of swelling in response to corticosteroid therapy. These techniques could be used as part of a randomized control trial to investigate the efficacy of corticosteroids for treating HSV encephalitis in conjunction with assessing clinical outcomes and could be of potential value in helping to predict the clinical outcomes of patients with HSV encephalitis

Paraphrastic Reformulations in Spoken Corpora

International audienceOur work addresses the automatic detection of paraphrastic reformulation in French spoken corpora. The proposed approach is syn-tagmatic. It is based on specific markers and the specificities of the spoken language. Manual multi-dimensional annotation performed by two annotators provides fine-grained reference data. An automatic method is proposed in order to decide whether sentences contain or not paraphras-tic relations. The obtained results show up to 66.4% precision. Analysis of the manual annotations indicates that few paraphrastic segments show morphological modifications (inflection, derivation or compounding) and that the syntactic equivalence between the segments is seldom respected, as these usually belong to different syntactic categories

Developing employability in higher education music

The development of employability in higher music education concerns students, musicians, educators, administrators and funding bodies, and yet employability is both impossible to measure and poorly defined. This paper sets the context for a set of short papers that explore employability from the perspective of music. Because many of the issues they raise have relevance across the creative industries, this paper discusses research that positions them within this broader context. The paper highlights the need for both the functional (how-to) aspects of employability and those that are cognitive: development of students' cognitive dispositions and their capacity to engage as professionals. As such, the paper argues that employability requires collaborative action on three fronts: enhancement of the ways in which employment outcomes are defined and measured; initiatives that engage students in career- and life-relevant activities; and advocacy work that re-aligns stakeholder perceptions of graduate work and employability itself

Mundane objects in the city: Laundry practices and the making and remaking of public/private sociality and space in London and New York

The paper considers how shifting laundry practices and technologies associated with dirty washing have over time summoned different spaces, socialities and socio-spatial assemblages in the city, enrolling different actors and multiple publics and constituting different associations, networks and relations in its wake as it travels from the home and back again. It argues that rather than being an inert object of unpleasant matter, whose encounter with humans has been largely restricted to certain categories of person for its transformation to re-use, and thus passed unnoticed, the paper explores how laundry practices have figured in producing and reproducing gendered (and classed) relations of labour, and enacting multiple socio-spatial, and gendered, relations and assemblages in the city, which have largely gone unnoticed in accounts of everyday urban life

Human Hookworm Infection Enhances Mycobacterial Growth Inhibition and Associates With Reduced Risk of Tuberculosis Infection

Soil-transmitted helminths and Mycobacterium tuberculosis frequently coincide geographically and it is hypothesized that gastrointestinal helminth infection may exacerbate tuberculosis (TB) disease by suppression of Th1 and Th17 responses. However, few studies have focused on latent TB infection (LTBI), which predominates globally. We performed a large observational study of healthy adults migrating from Nepal to the UK (n = 645). Individuals were screened for LTBI and gastrointestinal parasite infections. A significant negative association between hookworm and LTBI-positivity was seen (OR = 0.221; p = 0.039). Hookworm infection treatment did not affect LTBI conversions. Blood from individuals with hookworm had a significantly greater ability to control virulent mycobacterial growth in vitro than from those without, which was lost following hookworm treatment. There was a significant negative relationship between mycobacterial growth and eosinophil counts. Eosinophil-associated differential gene expression characterized the whole blood transcriptome of hookworm infection and correlated with improved mycobacterial control. These data provide a potential alternative explanation for the reduced prevalence of LTBI among individuals with hookworm infection, and possibly an anti-mycobacterial role for helminth-induced eosinophils.Wellcome Trust; British Lung Foundation; National Institute for Health Research Health Protection Research Unit (NIHR HPRU) in Emerging and Zoonotic Infections at the University of Liverpool in partnership with Public Health England (PHE), in collaboration with the Liverpool School of Tropical Medicine; Liverpool School of Tropical Medicine

Business models in rail infrastructure: explaining innovation

Policy decisions about the UK railway industry often draw on models and frameworks that treat technology and organisational processes as static and unchanging. As a result, policy makers often have limited understanding of how changes in policy will influence organisational knowledge, learning and the allocation of risk that subsequently affects innovation and system development. This paper applies a business model lens, focused on the mechanisms firms use to create and capture value, to connect policy decisions to subsequent changes in the organisation and industrial structure of the UK railway sector. By analysing innovation-related activity across several different governance structures, the paper highlights how policy impacts in network-based infrastructure sectors are mediated by business strategy, sometimes leading to unintended outcomes. The findings suggest that policy to improve the performance should focus upon coordination rather than just ownership. The application of a business model approach to complement existing economic and policy models in system analysis for policy decisions is advocated

The UK joint specialist societies guideline on the diagnosis and management of acute meningitis and meningococcal sepsis in immunocompetent adults.

Bacterial meningitis and meningococcal sepsis are rare conditions with high case fatality rates. Early recognition and prompt treatment saves lives. In 1999 the British Infection Society produced a consensus statement for the management of immunocompetent adults with meningitis and meningococcal sepsis. Since 1999 there have been many changes. We therefore set out to produce revised guidelines which provide a standardised evidence-based approach to the management of acute community acquired meningitis and meningococcal sepsis in adults. A working party consisting of infectious diseases physicians, neurologists, acute physicians, intensivists, microbiologists, public health experts and patient group representatives was formed. Key questions were identified and the literature reviewed. All recommendations were graded and agreed upon by the working party. The guidelines, which for the first time include viral meningitis, are written in accordance with the AGREE 2 tool and recommendations graded according to the GRADE system. Main changes from the original statement include the indications for pre-hospital antibiotics, timing of the lumbar puncture and the indications for neuroimaging. The list of investigations has been updated and more emphasis is placed on molecular diagnosis. Approaches to both antibiotic and steroid therapy have been revised. Several recommendations have been given regarding the follow-up of patients
