Meningococcal group B vaccine for the prevention of invasive meningococcal disease caused by Neisseria meningitidis serogroup B

Invasive meningococcal disease (IMD) is a major public health concern because of its high case fatality, long-term morbidity, and potential to course with outbreaks. IMD caused by Nesseira meningitidis serogroup B has been predominant in different regions of the world like Europe and only recently broadly protective vaccines against B serogroup have become available. Two protein-based vaccines, namely 4CMenB (Bexsero®) and rLP2086 (Trumenba®) are currently licensed for use in different countries against MenB disease. These vaccines came from a novel technology on vaccine design (or antigen selection) using highly specific antigen targets identified through whole-genome sequence analysis. Moreover, it has the potential to confer protection against non-B meningococcus and against other Neisserial species such as gonococcus. Real-world data on the vaccine-use are rapidly accumulating from the UK and other countries which used the vaccine for control of outbreak or as part of routine immunization program, reiterating its safety and efficacy. Additional data on real-life effectiveness, long-term immunity, and eventual herd effects, including estimates on vaccine impact for cost-effectiveness assessment are further needed. Given the predominance of MenB in Europe and other parts of the world, these new vaccines are crucial for the prevention and public health control of the disease, and should be considered.S

Addressing educational needs of teachers in the EU for inclusive education in a context of diversity (Inno4Div): Volume 2 - Literature review on key enabling components of teachers' intercultural and democratic competence development and their associated barriers

In spite of policy impetus, research shows that teachers struggle to address the increasing diversity in classrooms, among others, due to the lack of competences to deal with it. The acquisition of Intercultural Competence (IC), which could be defined as “the ability to mobilise and deploy relevant attitudes, skills, knowledge and values in order to interact effectively and appropriately in different intercultural situations”, is a crucial need for teachers to deal with diversity and to be successful in their teaching. In this context, in 2019 the JRC launched the INNO4DIV project with the aim to support polices in the field of IC of teachers, through the analysis of literature and innovative good practices which have successfully addressed the existing barriers for teacher´s IC development. Within this context, the main purpose of this deliverable is to provide an updated list of key enabling components (KECs) for the development of teachers’ intercultural and democratic competence and the barriers that hinder such development. The Literature review confirms prior research, which served as a departure point for the present study, and identified the following 8 KECs: 1. a common understanding of the knowledge skills and attitudes related to IC; 2. supporting policies; 3. effective initial teacher education curricula, including mandatory IC and related assessment methods, naming specific learning objectives and competences, and how to foster them with respective tools, methods and teaching approaches in classroom education as well as in extracurricular activities; 4. availability of high-quality professional IC courses for teachers’ continuous professional development; 5. integrated IC across the school curriculum; 6. the application of effective teaching methods, based on adapted pedagogical approaches such as: Peer-learning, IC networks, IC working groups in school, IC connections within and beyond teacher training, Experiential Learning Collaboration, Challenging assumptions, and Communities of Practice; 7. the availability of supporting tools; and, 8. a whole school approach to intercultural learning, framing, accompanying and supporting teachers IC learning and teaching activities, which needs to be promoted by policy makers and has to be put into practice by the respective educators and school administrators. In addition, the review detected a new essential KEC: Teacher educators with experiential knowledge about interculturality and diversity.JRC.B.4-Human Capital and Employmen

Addressing Educational Needs of Teachers in the EU for Inclusive Education in a Context of Diversity (INNO4DIV): Volume 3 - Part 1: Assessment guidelines for teacher education and training practices on intercultural and democratic competence development.

In spite of policy impetus, research shows that teachers struggle to address the increasing diversity in classrooms, among others, due to the lack of competences to deal with it. The acquisition of Intercultural Competence (IC), which could be defined as “the ability to mobilise and deploy relevant attitudes, skills, knowledge and values in order to interact effectively and appropriately in different intercultural situations”, is a crucial need for teachers to deal with diversity and to be successful in their teaching. In this context, in 2019 the JRC launched the INNO4DIV project with the aim to support polices in the field of IC of teachers, through the analysis of literature and innovative good practices which have successfully addressed the existing barriers for teacher´s IC development. In this context, it was necessary to identify innovative practices for overcoming barriers in the development of intercultural and democratic competences (IDC) of teachers. Given the wealth and variety of educational practices, and in order to preserve the scientific rigour of the identification process, this report offers the rationale and the description of the selection criteria that have been developed according to the conceptual framework of the project, Volume 1. Teachers ́ Intercultural Competence: Working definition and implications for teacher education. Similarly, the process for case identification and selection is also described. Following a brief explanation of the sources for the selection of cases (Section 2), the report focuses on establishing the selection criteria, which are divided into generic and specific criteria (Section 3). The generic criteria apply to all the cases. The specific criteria, however, relate to the scope of each specific Key Enabling Component (KEC), and are the most direct reference to the particular features of the cases. Finally, the document contains an elaborate protocol for case selection that will lead to the final list of selected cases.JRC.B.4-Human Capital and Employmen

Development and Validation of a New Clinical Scale for Infants with Acute Respiratory Infection: The ReSVinet Scale

Background and Aims A properly validated scoring system allowing objective categorization of infants with acute respiratory infections (ARIs), avoiding the need for in-person assessment and that could also be used by non-health professionals is currently not available. We aimed to develop a new clinical assessment scale meeting these specifications. Methods We designed a clinical scale (ReSVinet scale) based on seven parameters (feeding intolerance, medical intervention, respiratory difficulty, respiratory frequency, apnoea, general condition, fever) that were assigned different values (from 0 to 3) for a total of 20 points.170 children under two years of age with ARI were assessed independently by three pediatricians using this scale. Parents also evaluated their offspring with an adapted version of the scale in a subset of 61 cases. The scale was tested for internal consistency (Cronbach’s alpha), Pearson correlation coefficient for the items in the scale, inter-observer reliability (kappa index) and floor-ceiling effect. Results Internal consistency was good for all the observers, with the lowest Cronbach’s alpha being 0.72. There was a strong correlation between the investigators (r-value ranged 0.76–0.83) and also between the results obtained by the parents and the investigators(r = 0.73). Light’s kappa for the observations of the three investigators was 0.74. Weighted kappa in the group evaluated by the parents was 0.73. The final score was correlated with length of hospital stay, PICU admission and Wood-Downes Score. Conclusions The ReSVinet scale may be useful and reliable in the evaluation of infants with ARI, particularly acute bronchiolitis, even with data obtained from medical records and when employed by parents. Although further studies are necessary, ReSVinet scale already complies with more score validation criteria than the vast majority of the alternatives currently available and used in the clinical practiceThis work was supported by the Spanish Government (Research Program Health Research Fund – [http://www.gendres.org] (FIS; PI10/00540 y PI13/02382) National Plan I + D + I and FEDER funds) and Regional Galician funds (Promotion of Research Project 10 PXIB 918 184 PR) (FMT), and Ministerio de Ciencia e Innovación (SAF2011-26983) and the Plan Galego IDT, Xunta de Galicia (EM 2012/045) (AS).

Ethics Committee experience during COVID-19 emergency. A brief report

La crisis sanitaria motivada por el COVID-19 hace necesaria la puesta en marcha, con celeridad, de investigaciones encaminadas a generar evidencias científicas que incidan en el control de sus devastadores efectos. Por ello, fue necesario realizar ajustes en la dinámica de trabajo de los Comités de Ética de la Investigación así como priorizar y agilizar la evaluación de los proyectos relacionados con dicha enfermedad. Este trabajo pretende analizar la actividad la actividad evaluadora del Comité de Ética de la Investigación con Medicamentos de Galicia (CEIm-G) durante dicho período de emergencia sanitaria. Se evaluaron 81 proyectos de investigación, 73 de ellos de ámbito autonómico (62 unicéntricos), 4 nacionales y 4 internacionales. En 57 proyectos el dictamen fue favorable, 4 fueron retirados por los promotores, en 6 no procedía dictamen y 14 no respondieron a las aclaraciones solicitadas hasta la fecha del cierre del estudio. La causas más frecuentes de solicitud de aclaraciones estaban relacionadas con la metodología y a continuación con la hoja de información al paciente y el consentimiento informado. También es imprescindible abordar los aspectos relacionados con la intimidad de los datos personales y las muestras y tener en cuenta la carga de trabajo de los investigadores. Como propuesta de mejora, consideramos que se debe incidir en una mayor coordinación entre los diferentes equipos de investigación para tratar de obtener resultados más robustos

Higher COVID-19 pneumonia risk associated with anti-IFN-α than with anti-IFN-ω auto-Abs in children

We found that 19 (10.4%) of 183 unvaccinated children hospitalized for COVID-19 pneumonia had autoantibodies (auto-Abs) neutralizing type I IFNs (IFN-alpha 2 in 10 patients: IFN-alpha 2 only in three, IFN-alpha 2 plus IFN-omega in five, and IFN-alpha 2, IFN-omega plus IFN-beta in two; IFN-omega only in nine patients). Seven children (3.8%) had Abs neutralizing at least 10 ng/ml of one IFN, whereas the other 12 (6.6%) had Abs neutralizing only 100 pg/ml. The auto-Abs neutralized both unglycosylated and glycosylated IFNs. We also detected auto-Abs neutralizing 100 pg/ml IFN-alpha 2 in 4 of 2,267 uninfected children (0.2%) and auto-Abs neutralizing IFN-omega in 45 children (2%). The odds ratios (ORs) for life-threatening COVID-19 pneumonia were, therefore, higher for auto-Abs neutralizing IFN-alpha 2 only (OR [95% CI] = 67.6 [5.7-9,196.6]) than for auto-Abs neutralizing IFN-. only (OR [95% CI] = 2.6 [1.2-5.3]). ORs were also higher for auto-Abs neutralizing high concentrations (OR [95% CI] = 12.9 [4.6-35.9]) than for those neutralizing low concentrations (OR [95% CI] = 5.5 [3.1-9.6]) of IFN-omega and/or IFN-alpha 2

Plasma lipid profiles discriminate bacterial from viral infection in febrile children

Fever is the most common reason that children present to Emergency Departments. Clinical signs and symptoms suggestive of bacterial infection are often non-specific, and there is no definitive test for the accurate diagnosis of infection. The 'omics' approaches to identifying biomarkers from the host-response to bacterial infection are promising. In this study, lipidomic analysis was carried out with plasma samples obtained from febrile children with confirmed bacterial infection (n = 20) and confirmed viral infection (n = 20). We show for the first time that bacterial and viral infection produces distinct profile in the host lipidome. Some species of glycerophosphoinositol, sphingomyelin, lysophosphatidylcholine and cholesterol sulfate were higher in the confirmed virus infected group, while some species of fatty acids, glycerophosphocholine, glycerophosphoserine, lactosylceramide and bilirubin were lower in the confirmed virus infected group when compared with confirmed bacterial infected group. A combination of three lipids achieved an area under the receiver operating characteristic (ROC) curve of 0.911 (95% CI 0.81 to 0.98). This pilot study demonstrates the potential of metabolic biomarkers to assist clinicians in distinguishing bacterial from viral infection in febrile children, to facilitate effective clinical management and to the limit inappropriate use of antibiotics

Impact of infection on proteome-wide glycosylation revealed by distinct signatures for bacterial and viral pathogens

Mechanisms of infection and pathogenesis have predominantly been studied based on differential gene or protein expression. Less is known about posttranslational modifications, which are essential for protein functional diversity. We applied an innovative glycoproteomics method to study the systemic proteome-wide glycosylation in response to infection. The protein site-specific glycosylation was characterized in plasma derived from well-defined controls and patients. We found 3862 unique features, of which we identified 463 distinct intact glycopeptides, that could be mapped to more than 30 different proteins. Statistical analyses were used to derive a glycopeptide signature that enabled significant differentiation between patients with a bacterial or viral infection. Furthermore, supported by a machine learning algorithm, we demonstrated the ability to identify the causative pathogens based on the distinctive host blood plasma glycopeptide signatures. These results illustrate that glycoproteomics holds enormous potential as an innovative approach to improve the interpretation of relevant biological changes in response to infection
