Aphasia and reperfusion therapies in hyper-acute settings: a scoping review

Reperfusion therapies are medical treatments that restore blood flow either by surgical removal of a blood clot or with medications that dissolve clots. The introduction of reperfusion therapies has the potential to change the presentation of aphasia following acute ischaemic stroke (AIS). This scoping study will explore the relationship between aphasia and reperfusion therapies from a speech-language pathology perspective.A systematic literature search was performed on studies published up until October 2016. Relevant studies that reported on aphasia and reperfusion therapy were assessed for quality and the relationship between the two.Overall, 27 studies were identified, these studies were heterogeneous in nature. Despite speech-language pathologists filling a central role in management of aphasia, only seven of these studies mentioned involvement of speech-language pathologists, with minimal information about the precise nature of the involvement of speech-language pathology services.Based on this scoping review, reperfusion therapy appears to be impacting on the presentation of aphasia. A prospective study into reperfusion therapy and aphasia is required to inform speech-language pathologists on this patient population

Treating reading comprehension deficits in sub-acute brain injury rehabilitation: identifying clinical practice and management

There is limited evidence for cognitive-communication reading comprehension (CCRC) interventions for adults following acquired brain injury (ABI), particularly during sub-acute rehabilitation. The purpose of this study was to investigate the clinical practice of speech-language pathologists (SLPs) with CCRC deficits during sub-acute ABI rehabilitation and compare it to the best available evidence. An electronic survey was used to gather information from clinicians across Australia regarding clinical practice in the areas of assessment, intervention, treatment hierarchies and service delivery; survey questions were developed from an extensive review of the literature and expert clinician opinion. Survey findings were then compared with the literature in the form of a systematic review. Surveyed clinicians provided multiple interventions for CCRC rehabilitation, including impairment based (94.7%), activity based (94.7%) and reading strategy interventions (100.0%). Five strategies were used by>94% of SLPs (highlighting, identifying main points/wh- questioning, re-reading, summarising, reducing visual load). When compared with the literature, strong similarities were found for strategy-based interventions and individual service delivery, with broad similarities for functional and impairment-based interventions, and impairment based treatment hierarchies. Strong differences in assessment were identified. Strategy use reported in clinical practice (100.0% SLPs) was higher than in the literature. Further investigation into the effectiveness of specific reading strategies for people with ABI is warranted

Diagnostic utility of artificial intelligence for left ventricular scar identification using cardiac magnetic resonance imaging—A systematic review

BACKGROUND: Accurate, rapid quantification of ventricular scar using cardiac magnetic resonance imaging (CMR) carries importance in arrhythmia management and patient prognosis. Artificial intelligence (AI) has been applied to other radiological challenges with success. OBJECTIVE: We aimed to assess AI methodologies used for left ventricular scar identification in CMR, imaging sequences used for training, and its diagnostic evaluation. METHODS: Following PRISMA recommendations, a systematic search of PubMed, Embase, Web of Science, CINAHL, OpenDissertations, arXiv, and IEEE Xplore was undertaken to June 2021 for full-text publications assessing left ventricular scar identification algorithms. No pre-registration was undertaken. Random-effect meta-analysis was performed to assess Dice Coefficient (DSC) overlap of learning vs predefined thresholding methods. RESULTS: Thirty-five articles were included for final review. Supervised and unsupervised learning models had similar DSC compared to predefined threshold models (0.616 vs 0.633, P = .14) but had higher sensitivity, specificity, and accuracy. Meta-analysis of 4 studies revealed standardized mean difference of 1.11; 95% confidence interval -0.16 to 2.38, P = .09, I(2) = 98% favoring learning methods. CONCLUSION: Feasibility of applying AI to the task of scar detection in CMR has been demonstrated, but model evaluation remains heterogenous. Progression toward clinical application requires detailed, transparent, standardized model comparison and increased model generalizability

Germline ERCC excision repair 6 like 2 (ERCC6L2) mutations lead to impaired erythropoiesis and reshaping of the bone marrow microenvironment

Despite the inclusion of inherited myeloid malignancies as a separate entity in the World Health Organization Classification, many established predisposing loci continue to lack functional characterization. While germline mutations in the DNA repair factor ERCC excision repair 6 like 2 (ERCC6L2) give rise to bone marrow failure and acute myeloid leukaemia, their consequences on normal haematopoiesis remain unclear. To functionally characterise the dual impact of germline ERCC6L2 loss on human primary haematopoietic stem/progenitor cells (HSPCs) and mesenchymal stromal cells (MSCs), we challenged ERCC6L2-silenced and patient-derived cells ex vivo. Here, we show for the first time that ERCC6L2-deficiency in HSPCs significantly impedes their clonogenic potential and leads to delayed erythroid differentiation. This observation was confirmed by CIBERSORTx RNA-sequencing deconvolution performed on ERCC6L2-silenced erythroid-committed cells, which demonstrated higher proportions of polychromatic erythroblasts and reduced orthochromatic erythroblasts versus controls. In parallel, we demonstrate that the consequences of ERCC6L2-deficiency are not limited to HSPCs, as we observe a striking phenotype in patient-derived and ERCC6L2-silenced MSCs, which exhibit enhanced osteogenesis and suppressed adipogenesis. Altogether, our study introduces a valuable surrogate model to study the impact of inherited myeloid mutations and highlights the importance of accounting for the influence of germline mutations in HSPCs and their microenvironment.Peer reviewe

Narrative theology in Religious Education

This is an Author's Accepted Manuscript of an article published in British Journal of Religious Education, 20 March 2013. Copyright © 2013 Taylor & Francis. Available online at: http://www.tandfonline.com/10.1080/01416200.2013.785931This article advocates a pedagogy of Religious Education (RE) based upon a narratival framework informed by both narrative theology and narrative philosophy. Drawing on the work of narrative theologians including Stanley Hauerwas, the article outlines the nature of the framework, describes the four phases of learning that comprise the pedagogy, and explains how such an approach can overcome existing difficulties in how biblical texts are handled within RE. Working from the narrative assumption that individuals and communities are formed by reading, sharing and living within stories, it suggests that the pedagogy might encourage pupils to think about how the lives of Christians are shaped by their interpretations of biblical narratives, to offer their own interpretations of biblical and other texts, and to consider the stories – religious, non-religious or both – which shape their own lives. In so doing, the article moves away from a ‘proof-texting’ approach to the Bible towards one in which pupils are enabled to think about the significance of biblical narratives for both Christians and themselves

Resilience of benthic deep-sea fauna to mining activities

With increasing demand for mineral resources, extraction of polymetallic sulphides at hydrothermal vents, cobalt-rich ferromanganese crusts at seamounts, and polymetallic nodules on abyssal plains may be imminent. Here, we shortly introduce ecosystem characteristics of mining areas, report on recent mining developments, and identify potential stress and disturbances created by mining. We analyze species' potential resistance to future mining and perform meta-analyses on population density and diversity recovery after disturbances most similar to mining: volcanic eruptions at vents, fisheries on seamounts, and experiments that mimic nodule mining on abyssal plains. We report wide variation in recovery rates among taxa, size, and mobility of fauna. While densities and diversities of some taxa can recover to or even exceed pre-disturbance levels, community composition remains affected after decades. The loss of hard substrata or alteration of substrata composition may cause substantial community shifts that persist over geological timescales at mined sites. (C) 2017 Elsevier Ltd.
