    Listeria Monocytogenes Infection of Free-living Western European Hedgehogs (Erinaceus Europaeus)

    Get PDF
    Listeria monocytogenes is a ubiquitous environmental bacterium that causes disease in a wide range of species. Infection with this pathogen is most frequently diagnosed in ruminant livestock, but is also known to infect people and occasionally wildlife. Postmortem examinations of Western European hedgehogs (Erinaceus europaeus) in Great Britain (2011–2017) identified five (5/266, 2%, 95% confidence interval: 0.8–4.3%) animals with L. monocytogenes infection. The L. monocytogenes isolates comprised three serogroup 1/2a and two serogroup 4 from three multilocus sequence types (2, 37, and 121), all of which were different by single-nucleotide polymorphism analysis, indicating they were distinct and epidemiologically unrelated. These findings are consistent with hedgehogs contracting sporadic infection from the environment, perhaps through eating soil-dwelling invertebrates. Examination of data from scanning surveillance programs focused on other British wildlife species indicates that the hedgehog is one of the wildlife species from which L. monocytogenes has been most frequently identified to date in Great Britain. However, further studies of multiple taxa with comparable sampling efforts are required to assess the relative frequency of L. monocytogenes infection in different wildlife species. The bacterium was isolated from extraintestinal sites in multiple hedgehogs, which may indicate septicemia. However, histological examination was limited and could not discriminate subclinical infection from disease (i.e., listeriosis). Although L. monocytogenes is a zoonotic pathogen, disease in people is typically contracted from the ingestion of contaminated foods. The risk to immunocompetent people of contracting listeriosis from hedgehogs is considered very low to negligible

    Knockout of proton-neutron pairs from 16^{16}O with electromagnetic probes

    After recent improvements to the Pavia model of two-nucleon knockout from 16^{16}O with electromagnetic probes the calculated cross sections are compared to experimental data from such reactions. Comparison with data from a measurement of the 16^{16}O(e,e'pn) reaction show much better agreement between experiment and theory than was previously observed. In a comparison with recent data from a measurement of the 16^{16}O(γ\gamma,pn) reaction the model over-predicts the measured cross section at low missing momentum.Comment: 6 pages, 5 figure

    First measurements of the ^16O(e,e'pn)^14N reaction

    Get PDF
    This paper reports on the first measurement of the ^16O(e,e'pn)^14N reaction. Data were measured in kinematics centred on a super-parallel geometry at energy and momentum transfers of 215 MeV and 316 MeV/c. The experimental resolution was sufficient to distinguish groups of states in the residual nucleus but not good enough to separate individual states. The data show a strong dependence on missing momentum and this dependence appears to be different for two groups of states in the residual nucleus. Theoretical calculations of the reaction using the Pavia code do not reproduce the shape or the magnitude of the data.Comment: 10 pages, 11 figures, 2 tables, Accepted for publication in EPJ

    Priorities for research in child maltreatment, intimate partner violence and resilience to violence exposures:results of an international Delphi consensus development process

    Get PDF
    BACKGROUND: Intimate partner violence (IPV) and child maltreatment (CM) are major global public health problems. The Preventing Violence Across the Lifespan (PreVAiL) Research Network, an international group of over 60 researchers and national and international knowledge-user partners in CM and IPV, sought to identify evidence-based research priorities in IPV and CM, with a focus on resilience, using a modified Delphi consensus development process. METHODS: Review of existing empirical evidence, PreVAiL documents and team discussion identified a starting list of 20 priorities in the following categories: resilience to violence exposure (RES), CM, and IPV, as well as priorities that cross-cut the content areas (CC), and others specific to research methodologies (RM) in violence research. PreVAiL members (N = 47) completed two online survey rounds, and one round of discussions via three teleconference calls to rate, rank and refine research priorities. RESULTS: Research priorities were: to examine key elements of promising or successful programmes in RES/CM/IPV to build intervention pilot work; CC: to integrate violence questions into national and international surveys, and RM: to investigate methods for collecting and collating datasets to link data and to conduct pooled, meta and sub-group analyses to identify promising interventions for particular groups. CONCLUSIONS: These evidence-based research priorities, developed by an international team of violence, gender and mental health researchers and knowledge-user partners, are of relevance for prevention and resilience-oriented research in the areas of IPV and CM

    National survey of attitudes towards and intentions to vaccinate against COVID-19: implications for communications

    Get PDF
    OBJECTIVES: To examine public views on COVID-19 vaccination and consider the implications for communications and targeted support. DESIGN: Cross-sectional study. SETTING: Online and telephone nationally representative survey in Great Britain, January to February 2021. PARTICIPANTS: 4978 adults. Survey response rate was 84%, among the 5931 panellists invited. MAIN OUTCOME MEASURES: Sociodemographic characteristics (age, gender, ethnicity, education, financial status), COVID-19 status, vaccine acceptance, trust in COVID-19 vaccination information sources, perceptions of vaccination priority groups and perceptions of importance of second dose. RESULTS: COVID-19 vaccine acceptance (83%) was associated with increasing age, higher level of education and having been invited for vaccination. Acceptance decreased with unconfirmed past COVID-19, greater financial hardship and non-white British ethnicity; black/black British participants had lowest acceptance. Overall, healthcare and scientific sources of information were most trusted. Compared with white British participants, other ethnicities had lower trust in healthcare and scientific sources. Those with lower educational attainment or financial hardship had lower trust in healthcare and scientific sources. Those with no qualifications had higher trust in media and family/friends. While trust was low overall in community or faith leaders, it was higher among those with Asian/Asian British and black/black British ethnicity compared with white British participants. Views of vaccine prioritisation were mostly consistent with UK official policy but there was support for prioritising additional groups. There was high support for having the second vaccine dose. CONCLUSIONS: Targeted engagement is needed to address COVID-19 vaccine hesitancy in non-white British ethnic groups, in younger adults, and among those with lower education, greater financial hardship and unconfirmed past infection. Healthcare professionals and scientific advisors should play a central role in communications and tailored messaging is needed for hesitant groups. Careful communication around vaccination prioritisation continues to be required

    Current clinical practice in disabling and chronic migraine in the primary care setting: results from the European My-LIFE anamnesis survey.

    Migraine is a prevalent and disabling headache disorder that affects more than 1.04 billion individuals world-wide. It can result in reduction in quality of life, increased disability, and high socio-economic burden. Nevertheless, and despite the availability of evidence-based national and international guidelines, the management of migraine patients often remains suboptimal, especially for chronic migraine (CM) patients. My-LIFE anamnesis project surveyed 201 General practitioners (GPs) from 5 European countries (France, Germany, Italy, Spain, and the UK) with the aim of understanding chronic migraine (CM) patients' management in the primary care setting. In our survey, GPs diagnosed episodic migraine (EM) more often than CM (87% vs 61%, p < 0.001). We found that many CM patients were not properly managed or referred to specialists, in contrast to guidelines recommendations. The main tools used by primary-care physicians included clinical interview, anamnesis guide, and patient diary. Tools used at the first visit differed from those used at follow-up visits. Up to 82% of GPs reported being responsible for management of patients diagnosed with disabling or CM and did not refer them to a specialist. Even when the GP had reported referring CM patients to a specialist, 97% of them were responsible for their follow-up. Moreover, the treatment prescribed, both acute and preventive, was not in accordance with local and international recommendations. GPs reported that they evaluated the efficacy of the treatment prescribed mainly through patient perception, and the frequency of follow-up visits was not clearly established in the primary care setting. These results suggest that CM is underdiagnosed and undertreated; thereby its management is suboptimal in the primary care. There is a need of guidance in the primary care setting to both leverage the management of CM patients and earlier referral to specialists, when appropriate
