    Integrated epidemiology for vector-borne zoonoses

    No full text
    The development and application of interventions for the control of vector-borne zoonoses requires broad understanding of epidemiological linkages between vector, animal infection and human infection. However, there are significant gaps in our understanding of these linkages and a lack of appropriate data poses a considerable barrier to addressing this issue. A move towards strengthened surveillance of vectors and disease in both animal and human hosts, in combination with linked human-animal surveys, could form the backbone for epidemiological integration, enabling explicit assessment of the animal-human (and vector) interface, and subsequent implications for spill-over to human populations. Currently available data on the spatial distribution of human African trypanosomiasis allow an illustrative example

    Employing paramagnetic shift for responsive MRI probes

    Get PDF
    Paramagnetic metal ions with anisotropic magnetic susceptibilities can shift the proton NMR signals of chelating ligands beyond the diamagnetic range of endogenous proton resonances. Such large shifts, along with enhanced longitudinal relaxation rates, allow paramagnetic complexes to be exploited as molecular imaging probes for MRI. Paramagnetically-shifted imaging probes are detected directly against zero background, as opposed to the indirect induced relaxation enhancement of surrounding water molecules, and are reviewed herein. The development of ‘smart’ probes that are sensitive to their surrounding environment is also being developed, and some of the challenges faced for in vivo imaging are discussed, including issues of sensitivity and dose, biodistribution and clearance. Several examples of lanthanide complexes have been investigated, and more recently certain paramagnetic transition metal complexes are being considered as potential imaging agents

    Existence of maximizers for Sobolev-Strichartz inequalities

    We prove the existence of maximizers of Sobolev-Strichartz estimates for a general class of propagators, involving relevant examples, as for instance the wave, Dirac and the hyperbolic Schrodinger flows.Comment: 10 page

    A scoping review of guidelines on caries management for children and young people to inform UK undergraduate core curriculum development

    Get PDF
    BackgroundCurrent evidence in cariology teaching is not consistently reflected in paediatric dentistry in the United Kingdom (UK). Many dental schools are not consistently teaching biological approaches to caries management, with outdated or complex methods being taught outwith the purview of general dental practitioners. This scoping review aimed to map current guidelines on the management of caries in children and young people. This is part of a work package to inform the consensus and development of a UK-wide caries management curriculum for paediatric dentistry.MethodsA search of electronic databases for peer reviewed literature was performed using Cochrane Library, MEDLINE via PubMed, TRIP Medical Database and Web of Science. Hand searching was undertaken for grey literature (citations of sources of evidence, websites of global organisations and Google Web Searchℱ (Google LLC, California, USA). Results from databases were screened independently, concurrently by two reviewers. Full texts were obtained, and reviewers met to discuss any disagreement for both database and hand searching.ResultsThis review identified 16 guidelines suitable for inclusion. After quality appraisal, eight were selected for synthesis and interpretation. Key themes included the shift towards selective caries removal and avoidance of complete caries removal unless in specific circumstances in anterior teeth. For “early lesions” in primary and permanent teeth with and without cavitation, several guidelines recommend biological management including site specific prevention and fissure sealants.ConclusionsThis review mapping current cariology guidelines for children and young people found gaps in the literature including classification of early carious lesions and management of early cavitated lesions. Areas identified for further exploration include integration of biological caries management into treatment planning, selective caries removal and whether pulpotomy is specialist-level treatment, requiring referral. These results will inform consensus recommendations in the UK, using Delphi methods

    Biologics in severe asthma:A pragmatic approach for choosing the right treatment for the right patient

    Get PDF
    The development of monoclonal antibody therapies targeting specific components of the pathways relevant to asthma pathophysiology has revolutionized treatment of severe asthma both in adults and children and helped to further unravel the heterogeneity of this disease. However, the availability of multiple agents, often with overlapping eligibility criteria, creates a need for pragmatic guidance for specialists undertaking care of patients with severe asthma. In this review, we provide an overview of the data supporting the clinical efficacy of biologics in distinct asthma phenotypes/endotypes. We also focus on the role of biomarkers and treatable traits, including comorbidities, in the choice of asthma biologics, highlight which treatments have been demonstrated to be steroid sparing in corticosteroid dependent asthma, and provide practical guidance that can drive shared decision making on treatment choice with patients. In addition, we summarize what is known to date regarding long-term safety of these drugs, and lastly, discuss future directions in biologics research.</p
