    The aim of this study was to increase knowledge on therapy and educational objectives professionals work on with children with autism spectrum disorder (ASD) and to identify corresponding state of the art robots. Focus group sessions (n = 9) with ASD professionals (n = 53) from nine organisations were carried out to create an objectives overview, followed by a systematic literature study to identify state of the art robots matching these objectives. Professionals identified many ASD objectives (n = 74) in 9 different domains. State of the art robots addressed 24 of these objectives in 8 domains. Robots can potentially be applied to a large scope of objectives for children with ASD. This objectives overview functions as a base to guide development of robot interventions for these children

    The Multi-Scale Infrastructure for Chemistry and Aerosols (MUSICA)

    To explore the various couplings across space and time and between ecosystems in a consistent manner, atmospheric modeling is moving away from the fractured limited-scale modeling strategy of the past toward a unification of the range of scales inherent in the Earth system. This paper describes the forward-looking Multi-Scale Infrastructure for Chemistry and Aerosols (MUSICA), which is intended to become the next-generation community infrastructure for research involving atmospheric chemistry and aerosols. MUSICA will be developed collaboratively by the National Center for Atmospheric Research (NCAR) and university and government researchers, with the goal of serving the international research and applications communities. The capability of unifying various spatiotemporal scales, coupling to other Earth system components, and process-level modularization will allow advances in both fundamental and applied research in atmospheric composition, air quality, and climate and is also envisioned to become a platform that addresses the needs of policy makers and stakeholders

    Genomic investigations of unexplained acute hepatitis in children

    Since its first identification in Scotland, over 1,000 cases of unexplained paediatric hepatitis in children have been reported worldwide, including 278 cases in the UK1. Here we report an investigation of 38 cases, 66 age-matched immunocompetent controls and 21 immunocompromised comparator participants, using a combination of genomic, transcriptomic, proteomic and immunohistochemical methods. We detected high levels of adeno-associated virus 2 (AAV2) DNA in the liver, blood, plasma or stool from 27 of 28 cases. We found low levels of adenovirus (HAdV) and human herpesvirus 6B (HHV-6B) in 23 of 31 and 16 of 23, respectively, of the cases tested. By contrast, AAV2 was infrequently detected and at low titre in the blood or the liver from control children with HAdV, even when profoundly immunosuppressed. AAV2, HAdV and HHV-6 phylogeny excluded the emergence of novel strains in cases. Histological analyses of explanted livers showed enrichment for T cells and B lineage cells. Proteomic comparison of liver tissue from cases and healthy controls identified increased expression of HLA class 2, immunoglobulin variable regions and complement proteins. HAdV and AAV2 proteins were not detected in the livers. Instead, we identified AAV2 DNA complexes reflecting both HAdV-mediated and HHV-6B-mediated replication. We hypothesize that high levels of abnormal AAV2 replication products aided by HAdV and, in severe cases, HHV-6B may have triggered immune-mediated hepatic disease in genetically and immunologically predisposed children

    Relationship between molecular pathogen detection and clinical disease in febrile children across Europe: a multicentre, prospective observational study

    BackgroundThe PERFORM study aimed to understand causes of febrile childhood illness by comparing molecular pathogen detection with current clinical practice.MethodsFebrile children and controls were recruited on presentation to hospital in 9 European countries 2016-2020. Each child was assigned a standardized diagnostic category based on retrospective review of local clinical and microbiological data. Subsequently, centralised molecular tests (CMTs) for 19 respiratory and 27 blood pathogens were performed.FindingsOf 4611 febrile children, 643 (14%) were classified as definite bacterial infection (DB), 491 (11%) as definite viral infection (DV), and 3477 (75%) had uncertain aetiology. 1061 controls without infection were recruited. CMTs detected blood bacteria more frequently in DB than DV cases for N. meningitidis (OR: 3.37, 95% CI: 1.92-5.99), S. pneumoniae (OR: 3.89, 95% CI: 2.07-7.59), Group A streptococcus (OR 2.73, 95% CI 1.13-6.09) and E. coli (OR 2.7, 95% CI 1.02-6.71). Respiratory viruses were more common in febrile children than controls, but only influenza A (OR 0.24, 95% CI 0.11-0.46), influenza B (OR 0.12, 95% CI 0.02-0.37) and RSV (OR 0.16, 95% CI: 0.06-0.36) were less common in DB than DV cases. Of 16 blood viruses, enterovirus (OR 0.43, 95% CI 0.23-0.72) and EBV (OR 0.71, 95% CI 0.56-0.90) were detected less often in DB than DV cases. Combined local diagnostics and CMTs respectively detected blood viruses and respiratory viruses in 360 (56%) and 161 (25%) of DB cases, and virus detection ruled-out bacterial infection poorly, with predictive values of 0.64 and 0.68 respectively.InterpretationMost febrile children cannot be conclusively defined as having bacterial or viral infection when molecular tests supplement conventional approaches. Viruses are detected in most patients with bacterial infections, and the clinical value of individual pathogen detection in determining treatment is low. New approaches are needed to help determine which febrile children require antibiotics.FundingEU Horizon 2020 grant 668303

    Robot KASPAR as Mediator in Making Contact with Children with Autism:A Pilot Study

    Research findings suggest that robots can enhance interventions targeted at children with autism spectrum disorder. A pilot study was conducted at a special needs school to examine the effect of robot KASPAR on making contact with children with autism. Nine children between 8 and 12 years of age participated in this mixed methods study with ABAB design. Children participated in 4 sessions, two with KASPAR and two with their teacher (usual care) resulting in total in 36 (video recorded) sessions. Main outcomes were micro behaviours of the children during sessions and teacher reactions based on video recordings. Results indicated that children showed significantly more non-verbal imitation (pvalue = 0.028), touched the robot more often than they touched the teacher (e.g. for a high-five) (pvalue = 0.012), maintained their attention longer (pvalue = 0.011), and were less often distracted (pvalue = 0.021) in the KASPAR sessions compared to the teacher sessions. The children made more positive verbal utterances as a reaction to the teacher than they did to KASPAR (pvalue = 0.028). A clinically relevant difference was identified in the amount of non-verbal behaviours shown and in the spontaneous use of verbal utterances on initiative of the child, both in favour of the KASPAR condition. As a conclusion, KASPAR was able to make contact with the children and to catch and hold their attention longer and in a more focused manner than the teachers. Moreover, children seemed to be at ease and enjoying the interactions with the robot, which constitute important requirements for further learning and implementation

    Roles, strengths and challenges of using robots in interventions for children with autism apectrum disorder (ASD)

    No full text
    The aim of this research was to study roles, strengths and challenges of robot-mediated interventions using robot KASPAR for children with autism spectrum disorder (ASD). Twelve focus group sessions were organized in which 70 ASD care and/or education professionals participated. Six roles for KASPAR were identified: provoker, reinforcer, trainer, mediator, prompter, and diagnostic information provider. Strengths of KASPAR are related to personalisation possibilities, its playfulness, the action-reaction principle, its neutral expression, consistent and repetitive application of actions, possibilities to vary behaviour in a controlled manner and having an extra hand. Challenges of working with KASPAR were: limited reaction possibilities, possibility of children being scared of KASPAR, difficulties with generalisation or transfer and finally potential dependence on KASPAR
