    Negotiating additional learning needs reform in Wales: The voice of the ALNCO

    Full text link
    Through a focus on the work of the additional learning needs co-ordinator (ALNCo) and their collaboration with others, this article examines the policy–practice intersection, specifically focusing on inclusive education and practices to support additional learning needs in primary schools in Wales in response to recent educational reform. Our study gathered data from three focus groups of ALNCos across south Wales, with three participants in each group. Our findings explore ALNCos' sense of connectedness within the system and the conditions that supported the development of certain educational practices, some of which align with the new policy agenda and others which have their roots in the previous system of supporting children with special educational needs. Four key themes are presented: compliance with mandated practice, non-compliance and resistance to reform, the importance of accountability within local systems, and challenges of the ALNCo role.</p

    Physiology of bridging stent grafts after fenestrated/branched endovascular aortic repair: Where translational science meets the clinical profile

    Full text link
    Fenestrated/branched endovascular aortic repair emerges as the primary therapeutic modality for intricate aortic pathologies encompassing the paravisceral and thoracoabdominal segments, where bridging stent grafts (BSGs) play a vital role in linking the primary aortic endograft with target vessels. Bridging stent grafts can be categorized mainly into self‐expanding stent grafts (SESGs) and balloon‐expandable stent grafts (BESGs). Physiological factors significantly influence post‐complex endovascular aortic repair BSG behaviour, impacting clinical outcomes of SESGs and BESGs in different but overlapping ways. Crucial prerequisites for BSGs encompass not only flexibility but also resilience against mechanical stress and compliance mismatch, especially when bridging the rigid aortic main body with dynamic target vessels. The significance of considering these physiological factors in clinical decision‐making is underscored by recognizing the interplay between SESG and BESG characteristics, vessel physiology and patient haemorheology. Such factors include the anatomy and tortuosity of the vessel, diameter of the vessel and BSG, deployment and durability, extrinsic stenosis and respiratory motion. Haemorheological factors, such as anti‐thrombotic therapy and hydration status, need to be considered. This narrative review examines both in vitro and in vivo evidence regarding the impact of physiological factors on the behaviour of BSGs and assesses the consequences for clinical outcomes following complex endovascular aortic repair

    Anomaly-Based Intrusion Detection for IoMT Networks: Design, Implementation, Dataset Generation, and ML Algorithms Evaluation

    Full text link
    The Internet of Things has transformed the healthcare sector through the introduction of the Internet of Medical Things (IoMT) technology. However, IoMT networks remain vulnerable to a wide range of threats due to their resource-constrained characteristics and heterogeneity. Therefore, novel security mechanisms such as accurate and efficient Anomaly-based Intrusion Detection Systems (AIDSs), taking into consideration the inherent limitations of the IoMT networks, are necessary to be developed before IoMT networks reach their full potential in the market. This paper is an extension of our previous works and presents a new and refined design of a hybrid AIDS for IoMT networks. Furthermore, we provide implementation details on Raspberry Pi devices and performance evaluation results that demonstrate the efficacy of our approach. For its detection purposes, the AIDS employs Novelty detection and Outlier detection algorithms as these types of ML algorithms can detect both known and unknown types of attacks. Then, we tuned the hyperparameters of various Novelty Detection and Outlier Detection ML algorithms and evaluated their performance. Afterwards, the best performing ML algorithms (i.e., OCSVM, LOF, G_KDE, PW_KDE, B_GMM, MCD and IsoForest) are selected to be integrated into the AIDS deployed on an IoT/IoMT testbed. In addition, we evaluated the performance of the deployed AIDS during runtime, and the runtime evaluation results indicate: (i) a strong detection performance for some of the integrated ML algorithms, and (ii) a low computational cost (i.e., less than 1 % cpu usage) of the AIDS for all integrated ML algorithms.</p

    The Body Hotel Self-Care Suite Evaluation

    Full text link
    The Body Hotel Self-Care Suite project was designed to support NHS staff, particularly palliative-care nurses and allied health professionals based at Velindre University NHS Trust, in managing high levels of stress, burnout, and emotional challenges. It offered movement-based workshops designed to help health care professionals process grief, alleviate burnout, and integrate simple, body-focused self-care practices into daily NHS practice. This evaluation, conducted between January and June 2025, used a mixed-methods approach including interviews and a psychological safety questionnaire.Findings indicate that participants experienced improvements in personal well-being, including increased vitality, emotional resilience, self-awareness, confidence, and self-compassion. The sessions promoted a sense of playfulness and connection, helping staff to decompress and renew their energy. Professionally, the intervention enhanced multimodal communication, cross-cultural cohesion, team building, and the practical application of stress management tools, such as grounding and breathing techniques.Barriers to participation included initial resistance to movement-based approaches, workload pressures, scheduling inflexibility, and concerns about clinical relevance or peer judgment. Practical constraints such as limited space and administrative burdens also impacted engagement. Nonetheless, participants and stakeholders emphasised that embedding these practices into routine NHS operations, with managerial support, clear communication about benefits, and flexible delivery formats (including digital options), could improve engagement and lead to a greater, more lasting impact.Quantitative analysis revealed a statistically significant increase in social engagement post-intervention, reinforcing the perception of a supportive, non-threatening environment that fosters acceptance, trust, and open self-expression without fear of judgment.While the Body Hotel Self-Care Suite is not a cure for systemic NHS challenges, it offers valuable resources to strengthen staff resilience, improve team dynamics, and contribute positively to workplace culture and personal well-being. Recommendations include integrating sessions into regular work practices, simplifying evaluation processes, expanding hybrid delivery options, and ensuring visible leadership endorsement to maximise participation and impact
