    Herpes simplex virus type 2 (HSV-2) is the causative agent of genital herpes. Matsuzawa et al have demonstrated that, in a mouse model, HSV-2 pathology is influenced by the time infection occurs. Increased expression of the HSV-2 receptor Nectin-1 under the control of CLOCK coincided with an increase in viral titer suggesting that HSV-2 infection is regulated by the host circadian clock

    Introduction Despite limited evidence supporting the effectiveness of out-of-school suspension for rectifying behavioural issues, the practice continues. Certain demographic factors (male, ethnic minority, low SES) predict suspensions; however, developmental and family factors can also play a role. Knowledge of these factors may inform alternative practices aimed at limiting the practice of suspension. Objectives and Approach This study investigated the relationship between out-of-school suspensions and demographic, developmental, and family factors. Children suspended in early schooling may be particularly at risk of poor school outcomes; thus, our sample includes children in the first years of school. Linked administrative data were obtained for 14,269 children enrolled in grade 3 at public schools in Western Australia. Multilevel logistic regressions were run, grouped by school, with out-of-school suspensions predicted by: child and parent demographic characteristics; a measure of children’s school-entry development (the Australian Early Development Census); and indicators of family risk (parental psychiatric hospitalizations, parental criminal offending, child maltreatment). Results Approximately 2% of children had been suspended at least once by grade 3. Aboriginal children, boys, and children attending schools with high levels of socioeconomic disadvantage had significantly increased odds of being suspended from school (2 times, 6 times, and 3 times increase, respectively). Furthermore, children considered socially and emotionally vulnerable at school-entry were around 3 times more likely than their peers to be suspended in the first few years of school. Parental psychiatric hospitalizations, parental criminal offending, and child maltreatment all significantly predicted out-of-school suspensions. Odds increased exponentially with each additional family risk factor experienced in early childhood. Children experiencing all three family risk factors were almost 7 times more likely than their peers to be suspended at least once by grade 3. Conclusion/Implications Our results provide further justification for the implementation of alternatives to out-of-school suspension, as children who would most likely benefit from a stable, nurturing school environment were significantly more likely to be suspended. Schools need to be better supported by inter-agency collaboration to manage the complex needs of vulnerable children

    Introduction Children who have been maltreated during early childhood may experience a difficult transition into schooling, due to maladaptive development of the abilities that are important for positive school adaptation. An understanding of how different dimensions of maltreatment relate to children’s school readiness is important for informing appropriate supports for maltreated Objectives and Approach In this study, the Australian Early Development Census scores of 19,203 children were linked to information on child maltreatment allegations (substantiated and unsubstantiated), including the type of alleged maltreatment, the timing of the allegation (infancy-toddlerhood or preschool), and the total number of allegations (chronicity). Results Children with a maltreatment allegation had increased odds of poor school readiness in cognitive and non-cognitive domains. Substantiated maltreatment was associated with poor social and emotional development in children, regardless of maltreatment type, timing, or chronicity. For children with unsubstantiated maltreatment allegations, developmental outcomes according to the type of alleged maltreatment were more heterogeneous; however, these children were also at risk of poor school readiness irrespective of the timing and/or chronicity of the alleged maltreatment. Conclusion/Implications The findings suggest that all children with maltreatment allegations are at risk for poor school readiness; these children may benefit from additional support to increase the chance of a successful school transition. Interventions should commence prior to the start of school to mitigate early developmental difficulties

    Implementing resources to support the diagnosis and management of Chronic Fatigue Syndrome/Myalgic Encephalomyelitis (CFS/ME) in primary care: a qualitative study

    BACKGROUND: Previous research has highlighted that many GPs lack the confidence and knowledge to diagnose and manage people with CFS/ME. Following the development of an online training module for GPs, and an information pack and DVD for patients, this study explored the extent to which these resources can be implemented in routine primary care.METHODS: Semi structured qualitative interviews were completed with patients and GPs across North West England. All interviews were transcribed and analysed using open exploratory thematic coding. Following this thematic analysis, the authors conducted a further theory-driven analysis of the data guided by Normalisation Process Theory.RESULTS: When used in line with advice from the research team, the information resource and training were perceived as beneficial to both patients and GPs in the diagnosis and management of CFS/ME. However, 47 % of patients in this study did not receive the information pack from their GP. When the information pack was used, it was often incomplete, sent in the post, and GPs did not work with patients to discuss the materials. Only13 out of 21 practices completed the training module due to time pressures and the low priority placed on low prevalence, contentious, hard to manage conditions. When the module was completed, many GPs stated that it was not feasible to retain the key messages as they saw so few patients with the condition. Due to the complexity of the condition, GPs also believed that the diagnosis and management of CFS/ME should take place in a specialist care setting.CONCLUSION: While barriers to the implementation of training and resources for CFS/ME remain, there is a need to support CFS/ME patients to access reliable, evidence based information outside primary care. Our findings suggest that future research should develop an online resource for patients to support self-management

    Development and formative evaluation of patient research partner involvement in a multi-disciplinary European translational research project

    Patient and public involvement (PPI) improves the quality of health research and ensures that research is relevant to patients’ needs. Though PPI is increasingly evident in clinical and health services research, there are few examples in the research literature of effective PPI in translational and laboratory-based research. In this paper, we describe the development and evaluation of PPI in a multi-centre European project (EuroTEAM – Towards Early biomarkers in Arthritis Management) that included both translational and laboratory-based and psychosocial research. We found that although most PPI in EuroTEAM was centred around the psychosocial research, there were examples of PPI in the laboratory studies. As the project evolved, researchers became better at accommodating PPI and identifying PPI opportunities. It was generally agreed that PPI had a positive impact on the project overall, particularly on public engagement with the research. We concluded that the inclusion of both psychosocial and laboratory-based research in the same project facilitated PPI across all aspects of the research. In future projects, we would try to specify individual PPI activities in more detail at the project-planning stage, and better accommodate patient partners who are not native speakers of English. Background Patient and public involvement (PPI) enhances research quality and relevance and is central to contemporary health policy. The value of PPI has been recognised in rheumatology research, though there are limited examples of PPI in basic and translational science. The EU FP7 funded ‘EuroTEAM’ (Towards Early biomarkers in Arthritis Management) project was established to develop biomarker-based approaches to predict the future development of rheumatoid arthritis and incorporated psychosocial research to investigate the perceptions of ‘at risk’ individuals about predictive testing, and to develop informational resources about rheumatoid arthritis (RA) risk. Patient involvement was central to EuroTEAM from the inception of the project. The objective of this paper is to describe the development of PPI in EuroTEAM, formatively assess the impact of PPI from the perspectives of researchers and patient research partners (PRPs), reflect on successes and lessons learned, and formulate recommendations to guide future projects. Methods Two mixed-methods surveys (for PRPs and researchers) and a teleconference were undertaken to assess the impact of PPI on individual work packages and on EuroTEAM overall. Results There was consensus about the positive impact of PPI on the research and on the experiences of those involved. In particular, the positive impact of PPI on the personal development of researchers, and on effective public engagement with EuroTEAM research were highlighted. Researchers described adapting their practice in future projects to facilitate PPI. Spin-off projects and ongoing collaborations between PRPs and researchers reflected the value of PPI to participants. PPI was more frequently integrated in psychosocial research, though examples of PPI in laboratory/translational science were also described. PRPs asked for more opportunities to contribute meaningfully to basic scientific research and for more extensive feedback on their contributions. Conclusions The findings were used to formulate recommendations to guide effective involvement of patients in future similar projects, including identifying specific training requirements for PRPs and researchers, the identification of PRP focused tasks/deliverables at the project planning stage, and supporting access to involvement for all PRPs. Importantly, the distinctive multidisciplinary approach of EuroTEAM, incorporating both basic science and psychosocial research, facilitated patient involvement in the project overall

    Infectious viral particles in bioaerosols generated during laparoscopic surgery place staff and patients at significant risk of infection and contributed to the postponement of countless surgical procedures during the COVID-19 pandemic causing excess deaths. The implementation of devices that inactivate viral particles from bioaerosols aid in preventing nosocomial viral spread. We evaluated whether electrostatic precipitation (EP) is effective in capturing and inactivating aerosolised enveloped and non-enveloped viruses. Using a closed-system model mimicking release of bioaerosols during laparoscopic surgery, known concentrations of each virus were aerosolised, exposed to EP and collected for analysis. We demonstrate that both enveloped and non-enveloped viral particles were efficiently captured and inactivated by EP, which was enhanced by increasing the voltage to 10kV or using two discharge electrodes together at 8kV. This study highlights EP as an effective means for capturing and inactivating viral particles in bioaerosols, which may enable continued surgical procedures during future pandemics
