    Abstract Human Herpesvirus 8 (HHV-8) has been classified by sequence analysis of open reading frame (ORF) K1, ORF K15, and variable sequence loci within the central constant region. The purpose of this study was to examine the molecular epidemiology of HHV-8 in an Irish population. This retrospective study included 30 patients who had HHV-8 DNA detected in plasma. Nested end-point PCR was used to characterise four regions of the HHV-8 genome, K1, T0.7 (K12), ORF 75, and K15. Sequencing data were obtained for 23 specimens from 19 patients. Phylogenetic analysis of ORF K1 demonstrated that subtypes A, B, C and F were present in 37%, 11%, 47% and 5%, respectively. For T0.7 and ORF 75, sequencing data were obtained for 12 patients. For T0.7, subtypes A/C, J, B, R and Q were present in 58%, 17%, 8%, 8%, and 8%, respectively. For ORF 75, subtypes A, B, C and D were present in 58%, 8%, 25%, and 8%, respectively. K15 sequences were determined for 13 patients. 69% had the P allele and 31% had the M allele. The data generated by this study demonstrate that a broad variety of HHV-8 subtypes are represented in patients exhibiting HHV-8-related disease in Ireland, a low prevalence country. The predominance of C and A K1 subtypes was as expected for a Western European population. The 31% prevalence for K15 subtype M was higher than expected for a Western European population. This may represent the changing and evolving epidemiology in Ireland due to altered migration patterns.

    Abstract Bone tissue engineering is a promising treatment for bone loss that requires a combination of porous scaffold and osteogenic cells. The aim of this study was to evaluate and develop a tricomposite, biomimetic scaffold consisting of marine-derived biomaterials, namely, chitosan and fucoidan with hydroxyapatite (HA). The effects of chitosan, fucoidan and HA individually and in combination on the proliferation and differentiation of human mesenchymal stem cells (MSCs) were investigated. According to the SEM results, the tricomposite scaffold had a uniform porous structure, which is a key requirement for cell migration, proliferation and vascularisation. The presence of HA and fucoidan in the chitosan tricomposite scaffold was confirmed using FTIR, which showed a slight decrease in porosity and an increase in the density of the tricomposite scaffold compared to other formulations. Fucoidan was found to inhibit cell proliferation at higher concentrations and at earlier time points when applied as a single treatment, but this effect was lost at later time points. Similar results were observed with HA alone. However, both HA and fucoidan increased MSC mineralisation as measured by calcium deposition. Differentiation was significantly enhanced in MSCs cultured on the tricomposite, with increased alkaline phosphatase activity on days 17 and 25. In conclusion, the tricomposite is biocompatible, promotes osteogenesis, and has the structural and compositional properties required of a scaffold for bone tissue engineering. This biomaterial could provide an effective treatment for small bone defects as an alternative to autografts or be the basis for cell attachment and differentiation in ex vivo bone tissue engineering.

    Abstract To create functional tissue engineering scaffolds, biomaterials should mimic the native extracellular matrix of the tissue to be regenerated. Simultaneously, the survival and functionality of stem cells should also be enhanced to promote tissue organisation and repair. Hydrogels, but in particular, peptide hydrogels, are an emerging class of biocompatible scaffolds which act as promising self-assembling biomaterials for tissue engineering and regenerative therapies, ranging from articular cartilage regeneration at joint defects, to regenerative spinal cord injury following trauma. To enhance hydrogel biocompatibility, it has become imperative to consider the native microenvironment of the site for regeneration, where the use of functionalised hydrogels with extracellular matrix adhesion motifs has become a novel, emerging theme. In this review, we will introduce hydrogels in the context of tissue engineering, provide insight into the complexity of the extracellular matrix, investigate specific adhesion motifs that have been used to generate functionalised hydrogels and outline their potential applications in a regenerative medicine setting. It is anticipated that by conducting this review, we will provide greater insight into functionalised hydrogels, which may help translate their use towards therapeutic roles.

    Abstract The creation of scaffolds for cartilage tissue engineering has faced significant challenges in developing constructs that can provide sufficient biomechanical support and offer suitable degradation characteristics. Ideally, such tissue-engineering techniques necessitate the fabrication of scaffolds that mirror the mechanical characteristics of the articular cartilage while degrading safely without damaging the regenerating tissues. The aim of this study was to create porous, biomechanically comparable 3D-printed scaffolds made from Poly(L-lactide-co-glycolide) 85:15 and to assess their degradation at physiological conditions 37 °C in pH 7.4 phosphate-buffered saline (PBS) for up to 56 days. Furthermore, the effect of scaffold degradation on the cell viability and proliferation of human bone marrow mesenchymal stem cells (HBMSC) was evaluated in vitro. To assess the long-term degradation of the scaffolds, accelerated degradation tests were performed at an elevated temperature of 47 °C for 28 days. The results show that the fabricated scaffolds were porous with an interconnected architecture and had comparable biomechanical properties to native cartilage. The degradative changes indicated stable degradation at physiological conditions with no significant effect on the properties of the scaffold and biocompatibility of the scaffold to HBMSC. Furthermore, the accelerated degradation tests showed consistent degradation of the scaffolds even in the long term without the notable release of acidic byproducts. It is hoped that the fabrication and degradation characteristics of this scaffold will, in the future, translate into a potential medical device for cartilage tissue regeneration.

    Abstract Marine organisms represent a highly diverse reserve of bioactives which could aid in the treatment of a wide range of diseases, including various musculoskeletal conditions. Osteoporosis in particular would benefit from a novel and effective marine-based treatment, due to its large disease burden and the inefficiencies of current treatment options. Osteogenic bioactives have been isolated from many marine organisms, including nacre powder derived from molluscan shells and fucoidan-the sulphated polysaccharide commonly sourced from brown macroalgae. Such extracts and compounds are known to have a range of osteogenic effects, including stimulation of osteoblast activity and mineralisation, as well as suppression of osteoclast resorption. This review describes currently known soluble osteogenic extracts and compounds from marine invertebrates and algae, and assesses their preclinical potential.

    Abstract Background: Therapy interventions emerged four times in the top 10 research priorities in a James Lind Alliance research prioritisation exercise for children with neurodisabilities (Morris C, Simkiss D, Busk M, Morris M, Allard A, Denness J,
    Objectives: The objectives were to (1) describe the current practice, approaches and schools of thought in relation to physiotherapy, occupational therapy and speech and language therapy for children with neurodisability; (2) explore clinical decision-making; (3) investigate views on outcomes and their measurement, particularly participation as an outcome, that is, the child's ability to have the opportunity to be involved in life situations and activities (e.g. communication, mobility, interpersonal interactions, self-care, learning and applying knowledge); (4) seek views on the aspects of therapy interventions that have an impact on outcomes; and (5) elicit stakeholder views on research needs and priorities.
    Design, setting and participants: More than 70 professionals (therapists, service leads, paediatricians and education staff) and 25 parents participated in a qualitative interview (either individually or as part of a focus group).
    Results: Professional thinking and models of service delivery are in a state of flux and development. There is a move towards goals-focused, family-centred approaches. Work tends to be highly individualised, with few protocols. Parents are certain of the value of therapies, although they may experience difficulties with provision and may seek (additional) private provision. Therapy interventions are conceived as three components: the therapist, the procedures/equipment, etc., and the wider therapeutic environment. They are believed to be highly complex and poorly understood. Although participation is widely endorsed as a core intervention objective of therapy interventions, its suitability, or appropriateness, as an outcome measure was questioned. Other child and/or parent outcomes were identified as more or equally important. Notions of intermediate outcomes - in terms of body structure/function, and the achievement of activities - were regarded as important and not counter to participation-focused approaches. Among therapists, research on intervention effectiveness was (cautiously) welcomed. A number of methodological challenges were identified. A portfolio of study designs - quantitative and qualitative, experimental and observational - was called for, and which included economic evaluation and clear pathways to impact.
    Limitations: The study was not successful in recruiting children and young people. Further work is required to elucidate the views of this key stakeholder group.
    Conclusions: Therapy interventions are poorly understood. There was strong support, tempered a little by concerns among some about the feasibility of demonstrating impact, for investment in research.
    Future work: The identification of research priorities was a core study objective, and a wide-ranging research agenda was identified. It included 'foundational' research into neurodisability, the active components of therapy interventions and the concept of participation. Three areas of evaluation were identified: overall approaches to therapy, service organisation and delivery issues, and the evaluation of specific techniques. Parents regarded evaluations of approaches to therapy (e.g. goals-focused; supporting family-self management) as priorities, along with evaluations of models of service provision. Professionals' views were broadly similar, with an additional emphasis on methodological research. In terms of specific techniques, there was no shared agreement regarding priorities, with views informed by personal interests and experiences.

    Abstract Background: Chronic suppurative otitis media (CSOM) causes preventable deafness and disproportionately affects children living in poverty. Our hypothesis was that health promotion in women's groups would increase their knowledge, attitudes and practices (KAP) regarding ear disease and reduce the prevalence of CSOM in their children.
    Methods: We did a cluster randomised trial in two village development committees (VDCs) in Jumla, Nepal. In July 2014, 30 women's groups were randomly allocated to intervention or control, stratified by VDC and distance to the road. The intervention groups participated in three sessions of health promotion using the WHO Hearing and Ear Care Training Resource Basic Level. The primary outcome was women's KAP score and the secondary outcome was prevalence of CSOM in their children at 12 month follow-up. Analyses were by intention to treat. Participants and the research team were not masked to allocation.
    Results: In June and July 2014 we recruited 508 women and 937 of their children. 12 months later there was no difference in the women's KAP score (mean difference 0.14, 95% CI - 0.1 to 0.38, P = 0.25) or the prevalence of CSOM in their children (OR 1.10, 95%CI 0.62 to 1.84, P = 0.75) between intervention and control groups. However, overall, there was a significant improvement in the KAP score (mean difference - 0.51, 95% CI - 0.71,to - 0.31, P < 0.0001) and in the prevalence of CSOM from baseline 11.2% to follow-up 7.1% (P < 0.0001).
    Conclusions: Health promotion in women's groups did not improve maternal KAP or reduce prevalence of CSOM. Over time there was a significant improvement in women's KAP score and reduction in the prevalence of CSOM which may be attributable to our presence in the community offering treatment to affected children, talking to their parents and providing ciprofloxacin drops to the local health posts. More research is needed in low resource settings to test our findings.
