RESUMO
BACKGROUND: Care home residents live with frailty and multiple long-term conditions. Their medical management is complex and specialised. We set out to develop a list of core competencies for doctors providing medical care in long-term care homes. METHODS: A scoping review searched MEDLINE, EMBASE and CAB Abstracts, supplemented by grey literature from the Portal of Online Geriatrics Education and the International Association of Geriatrics and Gerontology, looking for core competencies for doctors working in care homes. These were mapped to the UK nationally mandated Generic Professional Competencies Framework. A Delphi exercise was conducted over three rounds using a panel of experts in care homes and medicine of older people. Competencies achieving 80% agreement for inclusion/exclusion were rejected/accepted, respectively. RESULTS: The scoping review identified 22 articles for inclusion, yielding 124 competencies over 21 domains. The Delphi panel comprised 23 experts, including 6 geriatricians, 4 nurses, 3 general practitioners, 2 advanced clinical practitioners, 2 care home managers, and one each of a patient and public representative, palliative care specialist, psychiatrist, academic, physiotherapist and care home audit lead. At the end of three rounds, 109 competencies over 19 domains were agreed. Agreement was strongest for generic competencies around frailty and weaker for sub-specialist knowledge about specific conditions and competencies related to care home medical leadership and management. CONCLUSION: The resulting competencies provide the basis of a curriculum for doctors working in long-term care homes for older people. They are specialty agnostic and could be used to train general practitioners or medical specialty doctors.

BACKGROUND: Despite recent focus on improving health care in care homes, it is unclear what role general practitioners (GPs) should play. To provide evidence for future practice we set out to explore how GPs have been involved in such improvements. METHODS: Realist review incorporated theory-driven literature searches and stakeholder interviews, supplemented by focussed searches on GP-led medication reviews and end-of-life care. Medline, Embase, CINAHL, PsycInfo, Web of Science, and the Cochrane library were searched. Grey literature was identified through internet searches and professional networks. Studies were included based upon relevance. Data were coded to develop and test contexts, mechanisms, and outcomes for improvements involving GPs. RESULTS: Evidence was synthesized from 30 articles. Programme theories described: (i) "negotiated working with GPs," where other professionals led improvement and GPs provided expertise; and (ii) "GP involvement in national/regional improvement programmes." The expertise of GPs was vital to many improvement programmes, with their medical expertise or role as coordinators of primary care proving pivotal. GPs had limited training in quality improvement (QI) and care home improvement work had to be negotiated in the context of wider primary care commitments. CONCLUSIONS: GPs are central to QI in health care in care homes. Their contributions relate to their specialist expertise and recognition as leaders of primary care but are challenged by available time and resources to develop this role.

OBJECTIVES: To describe and explain the outcomes of community dementia friendly initiatives (DFIs) for people with dementia and their caregivers to inform the development and tailoring of DFIs. METHODS: Literature searches on DFIs were performed through two systematic online database searches of PubMed, Embase, ASSIA, CINAHL and Google scholar. Papers were only included if they evaluated outcomes using empirical data from people with dementia or caregivers. Data collection and analysis were guided by the categorization in the DEM-FACT taxonomy and RAMESES guidelines for realist reviews. RESULTS: Of 7154 records identified, 22 papers were included with qualitative, mixed method and quantitative study designs. The synthesis led to a description of programme theories addressing caring, stimulating and activating communities. Outcomes for people with dementia and caregivers included having contact with others, enjoyment and decrease of stress and, lastly, support. This synthesis also indicated how people with dementia participated in a specific role in DFIs, such as patient, team member or active citizen. CONCLUSIONS: DFIs generate different outcomes for people with dementia and caregivers, depending on the kind of initiative and the specific role for people with dementia. These findings could be a catalyst for initiation and further development of DFIs in a dementia friendly community (DFC). This draws attention to the multiple aspects of DFCs and supports reflection on their essential principles.

BACKGROUND: Quality improvement collaboratives (QICs) bring together multidisciplinary teams in a structured process to improve care quality. How QICs can be used to support healthcare improvement in care homes is not fully understood. METHODS: A realist evaluation to develop and test a programme theory of how QICs work to improve healthcare in care homes. A multiple case study design considered implementation across 4 sites and 29 care homes. Observations, interviews and focus groups captured contexts and mechanisms operating within QICs. Data analysis classified emerging themes using context-mechanism-outcome configurations to explain how NHS and care home staff work together to design and implement improvement. RESULTS: QICs will be able to implement and iterate improvements in care homes where they have a broad and easily understandable remit; recruit staff with established partnership working between the NHS and care homes; use strategies to build relationships and minimise hierarchy; protect and pay for staff time; enable staff to implement improvements aligned with existing work; help members develop plans in manageable chunks through QI coaching; encourage QIC members to recruit multidisciplinary support through existing networks; facilitate meetings in care homes and use shared learning events to build multidisciplinary interventions stepwise. Teams did not use measurement for change, citing difficulties integrating this into pre-existing and QI-related workload. CONCLUSIONS: These findings outline what needs to be in place for health and social care staff to work together to effect change. Further research needs to consider ways to work alongside staff to incorporate measurement for change into QI.

BACKGROUND: Equality of access to memory assessment services by older adults from ethnic minorities is both an ethical imperative and a public health priority. OBJECTIVE: To investigate whether timeliness of access to memory assessment service differs between older people of white British and South Asian ethnicity. DESIGN: Longitudinal cohort. SETTING: Nottingham Memory Study; outpatient secondary mental healthcare. SUBJECTS: Our cohort comprised 3654 white British and 32 South Asian older outpatients. METHODS: The criterion for timely access to memory assessment service was set at 90 days from referral. Relationships between ethnicity and likelihood of timely access to memory assessment service were analysed using binary logistic regression. Analyses were adjusted for socio-demographic factors, deprivation and previous access to rapid response mental health services. RESULTS: Among white British outpatients, 2272 people (62.2%) achieved timely access to memory assessment service. Among South Asian outpatients, fourteen people (43.8%) achieved timely access to memory assessment service. After full adjustment, South Asian outpatients had a 0.47-fold reduced likelihood of timely access, compared to white British outpatients (odds ratio 0.47, 95% confidence interval 0.23-0.95, P value = .035). The difference became non-significant when restricting analyses to outpatients reporting British nationality or English as first language. Older age, lower index of deprivation and previous access to rapid response mental health services were associated with reduced likelihood of timely access, while gender was not. CONCLUSIONS: In a UK mental healthcare service, older South Asian outpatients are less likely to access dementia diagnostic services in a timely way, compared to white British outpatients.

BACKGROUND: undertaking comprehensive geriatric assessments (CGAs) combined with long-term health and social care management can improve the quality of life of older people [ 1]. The EASY-Care tool is a CGA instrument designed for assessing the physical, mental and social functioning and unmet health and social needs of older people in community settings or primary care. It has also been used as a frailty assessment tool and for gathering population-level data. OBJECTIVE: to review the evidence of reliability, validity and acceptability of EASY-Care and its appropriateness for assessing the needs of community-dwelling older people. METHODS: systematic search of literature databases using pre-defined search terms (January 1994-May 2014) for English language articles reporting on the reliability, validity, acceptability and implementation of EASY-Care in primary care and community settings. Eligible articles were critically reviewed. Discussion papers mapping professionals' use of the tool were also included as these could be considered an aspect of validity. RESULTS: twenty-nine papers met the inclusion criteria and underwent data extraction. A narrative synthesis was performed, because there was a variety of quantitative and qualitative outcomes and characteristics. Reliability evidence for EASY-Care is minimal. Evidence for validity is good, and it has received numerous positive endorsements of acceptability in international settings from older people and practitioners. CONCLUSION: evidence supports the use of EASY-Care for individual needs assessment; further research is needed for other uses. Of the papers that made statements about who should administer EASY-Care, the majority indicated that nurses were preferable to self-completion.

BACKGROUND: Phenylketonuria (PKU) is the most common inherited disease of amino acid metabolism, characterised by elevated levels of phenylalanine (Phe). There is a lack of infant feeding guidance for those with PKU. From birth to 6 months of age, breast feeding is the optimal nutrition for an infant and continuing breast feeding for infants with PKU is recommended by European guidelines. However, human breast milk contains Phe in varying quantities, and therefore, the effects breast feeding might have on infants with PKU needs careful consideration. AIM: To assess the effects of breast feeding (exclusive or partial) compared with low-Phe formula feeding in infants diagnosed with PKU, on blood Phe levels, growth and neurodevelopmental scores. METHODS: The Cochrane Inborn Errors of Metabolism Trials Register, MEDLINE and Embase were searched (date of latest search: 9 August 2022). Studies were included if they looked at the effects of breast feeding in infants diagnosed with PKU compared with formula feeding. Predetermined outcomes included blood Phe levels, growth in the first 2 years of life and neurodevelopmental scores. RESULTS: Seven observational studies (282 participants) met the inclusion criteria. All studies compared continuation of breast feeding with low-Phe formula versus formula feeding only. While most studies concluded that there was no difference in mean serum Phe levels in their follow-up period, two reported that breastfed infants were more likely to have a normal mean Phe level. Two studies described no difference in mean weight gain after birth, while one found that breastfed infants were more likely to have higher mean weight gain. Two studies commented that breastfed infants achieved higher developmental scores in childhood as compared with formula fed infants. CONCLUSION: Although there are no randomised trials, observational evidence suggests that continuation of breast feeding and supplementation with low-Phe formula is safe and may be beneficial for infants diagnosed with PKU.

PURPOSE: We conducted a scoping review of quality improvement in care homes. We aimed to identify participating occupational groups and methods for evaluation. Secondly, we aimed to describe resident-level interventions and which outcomes were measured. METHODS: Following extended PRISMA guideline for scoping reviews, we conducted systematic searches of Medline, CINAHL, Psychinfo, and ASSIA (2000-2019). Furthermore, we searched systematic reviews databases including Cochrane Library and JBI, and the grey literature database, Greylit. Four co-authors contributed to selection and data extraction. RESULTS: Sixty five studies were included, 6 of which had multiple publications (75 articles overall). A range of quality improvement strategies were implemented, including audit feedback and quality improvement collaboratives. Methods consisted of controlled trials, quantitative time series and qualitative interview and observational studies. Process evaluations, involving staff of various occupational groups, described experiences and implementation measures. Many studies measured resident-level outputs and health outcomes. 14 studies reported improvements to a clinical measure; however, four of these articles were of low quality. Larger randomised controlled studies did not show statistically significant benefits to resident health outcomes. CONCLUSION: In care homes, quality improvement has been applied with several different strategies, being evaluated by a variety of measures. In terms of measuring benefits to residents, process outputs and health outcomes have been reported. There was no pattern of which quality improvement strategy was used for which clinical problem. Further development of reporting of quality improvement projects and outcomes could facilitate implementation.

INTRODUCTION: Older people who live in care homes have a high level of need with complex health conditions. In addition to providing medical care to residents, general practitioners (GPs) play a role as gatekeeper for access to services, as well as leadership within healthcare provision. This review will describe how GPs were involved in initiatives to change arrangements of healthcare services in order to improve quality and experience of care. METHODS AND ANALYSIS: Following RAMESES quality and publication guidelines standards, we will proceed with realist review to develop theories of how GPs work with care home staff to bring about improvements. We identify when improvement in outcomes does not occur and why this may be the case. The first stage will include interviews with GPs to ask their views on improvement in care homes. These interviews will enable development of initial theories and give direction for the literature searches. In the second stage, we will use iterative literature searches to add depth and context to the early theories; databases will include Medline, Embase, CINAHL, PsycINFO and ASSIA. In stage 3, evidence that is judged as rigorous and relevant will be used to test the initial theories, and through the process, refine the theory statements. In the final stage, we will synthesise findings and provide recommendations for practice and policy-making.During the review, we will invite a context expert group to reflect on our findings. This group will have expertise in current trends in primary care and the care home sector both in UK and internationally. ETHICS AND DISSEMINATION: The study was approved by University of Nottingham Faculty of Medicine and Health Sciences Research Ethics Committee: 354-1907. Findings will be shared through stakeholder networks, published in National Institute for Health Research journal and submitted for peer-reviewed journal publication.

OBJECTIVES: First point of contact physiotherapy (FPCP) provides patients direct access to a physiotherapist. Literature demonstrates efficacy of FPCP. Evidence has highlighted the need for cultural shifts from both patient and professional perspectives to optimise FPCP. This study explored stakeholder perceptions of patient awareness and understanding of FPCP to better inform FPCP implementation. DESIGN, SETTING, PARTICIPANTS: A qualitative methodology utilised semi-structured interviews and focus groups. Findings from a previous realist review were used to generate a priori topic guides. Participants included patients, physiotherapists, GPs, administration staff, and commissioners. A thematic analysis was undertaken. RESULTS: Four themes emerged that are described: level of patient awareness of the FPCP role situated against the GP as first contact practitioner, patients attain an awareness of FPCP from a variety of sources, patient understanding of physiotherapy arises from several sources and is poorly aligned with the FPCP model, characteristics and behaviours of patients influence access to FPCP services. Patient awareness and understanding was poor. Patients tended to view the GP as the default first contact practitioner. Traditional advertising approaches appeared on the whole invisible to patients and there was a reliance on signposting to facilitate patient access. CONCLUSION: Findings from this study can inform implementation of FPCP. Several obstacles to the optimisation of FPCP were highlighted. Improved marketing of physiotherapy generally and FPCP specifically may increase patient awareness and understanding. However, it is likely further time will be required to bring about the cultural shift in public perception required to optimise the potential of FPCP.

The Breakthrough Series Quality Improvement Collaborative (QIC) initiative is a well-developed and widely used approach, but most of what we know about it has come from healthcare settings. In this article, those leading QICs to improve care in care homes provide detailed accounts of six QICs and share their learning of applying the QIC approach in the care home sector. Overall, five care home-specific lessons were learnt: (i) plan for the resources needed to support collaborative teams with collecting, processing, and interpreting data; (ii) create encouraging and safe working environments to help collaborative team members feel valued; (iii) recruit collaborative teams, QIC leads, and facilitators who have established relationships with care homes; (iv) regularly check project ideas are aligned with team members' job roles, responsibilities, and priorities; and (v) work flexibly and accept that planned activities may need adapting as the project progresses. These insights are targeted at teams delivering QICs in care homes. These insights demonstrate the need to consider the care home context when applying improvement tools and techniques in this setting.

AIM: This exploratory study of commissioning third sector services for older people aimed to explore whether service data was fed back to commissioners and whether this could improve intelligence about the population and hence inform future commissioning decisions. BACKGROUND: Third sector services are provided through charities and non-profit community organizations, and over recent years services have developed that assess and advise people for self-management or provide wellbeing support in the community. Third sector services have an opportunity to reach vulnerable populations and to provide intelligence about them. Some third sector services are state funded (commissioned) in the United Kingdom. While evidence is available about the commissioning of statutory health and social care, as well as private providers, there is limited evidence about how third sector health services are funded. METHODS: Participants were recruited from commissioner organizations and third sector organizations, both with an interest in supporting the independence, self-management and wellbeing of older people. Organizations were recruited from five purposively selected sites within one region of England (East Midlands). Semi-structured interviews explored the relationships between commissioners and providers and the nature of funding arrangements, including co-production. Interviews also explored collection of data within the service and how data were fed back to commissioners. Focus groups were held with older people with the potential to benefit from wellbeing services. RESULTS: Commissioning arrangements were varied, sometimes complex, and often involved co-production with the third sector. Commissioners valued third sector organizations for their engagement with the local community, value for money, outreach services and ability to provide information about the community. Assessing the needs and outcomes of individuals was integral to delivery of support and advice to older people. Diverse approaches were used to assess an individual's needs and outcomes, although there were concerns that some assessment questionnaires may be too complex for this vulnerable group. Assessment and outcomes data were also used to monitor the service contract and there was potential for the data to be summarized to inform commissioning strategies, but commissioners did not report using assessment data in this way, in practice. While the policy context encouraged partnerships with third sector organizations and their involvement in decision making, the relationship with third sector organizations was not valued within contract arrangements, and may have been made more difficult by the tendering process and the lack of analysis of service data. CONCLUSION: This exploratory study has demonstrated a diversity of commissioning arrangements for third sector services across one region of England. Most commissioners invited co-production; that is, the commissioners sought input from the third sector while specifying details of the service. Service data, including assessments of needs and outcomes, were reported to commissioners, however commissioners did not appear to use this to full advantage to inform future commissioning decisions. This may indicate a need to improve measurement of needs and outcomes in order to improve the credibility of the commissioning process.

OBJECTIVES: Comprehensive geriatric assessment (CGA) may be a way to deliver optimal care for care home residents. We used realist review to develop a theory-driven account of how CGA works in care homes. DESIGN: Realist review. SETTING: Care homes. METHODS: The review had three stages: first, interviews with expert stakeholders and scoping of the literature to develop programme theories for CGA; second, iterative searches with structured retrieval and extraction of the literature; third, synthesis to refine the programme theory of how CGA works in care homes.We used the following databases: Medline, CINAHL, Scopus, PsychInfo, PubMed, Google Scholar, Greylit, Cochrane Library and Joanna Briggs Institute. RESULTS: 130 articles informed a programme theory which suggested CGA had three main components: structured comprehensive assessment, developing a care plan and working towards patient-centred goals. Each of these required engagement of a multidisciplinary team (MDT). Most evidence was available around assessment, with tension between structured assessment led by a single professional and less structured assessment involving multiple members of an MDT. Care planning needed to accommodate visiting clinicians and there was evidence that a core MDT often used care planning as a mechanism to seek external specialist support. Goal-setting processes were not always sufficiently patient-centred and did not always accommodate the views of care home staff. Studies reported improved outcomes from CGA affecting resident satisfaction, prescribing, healthcare resource use and objective measures of quality of care. CONCLUSION: The programme theory described here provides a framework for understanding how CGA could be effective in care homes. It will be of use to teams developing, implementing or auditing CGA in care homes. All three components are required to make CGA work-this may explain why attempts to implement CGA by interventions focused solely on assessment or care planning have failed in some long-term care settings. TRIAL REGISTRATION NUMBER: CRD42017062601.

: Background: Technology-enabled healthcare or smart health has provided a wealth of products and services to enable older people to monitor and manage their own health conditions at home, thereby maintaining independence, whilst also reducing healthcare costs. However, despite the growing ubiquity of smart health, innovations are often technically driven, and the older user does not often have input into design. The purpose of the current study was to facilitate a debate about the positive and negative perceptions and attitudes towards digital health technologies. Methods: We conducted citizens' juries to enable a deliberative inquiry into the benefits and risks of smart health technologies and systems. Transcriptions of group discussions were interpreted from a perspective of life-worlds versus systems-worlds. Results: Twenty-three participants of diverse demographics contributed to the debate. Views of older people were felt to be frequently ignored by organisations implementing systems and technologies. Participants demonstrated diverse levels of digital literacy and a range of concerns about misuse of technology. Conclusion: Our interpretation contrasted the life-world of experiences, hopes, and fears with the systems-world of surveillance, efficiencies, and risks. This interpretation offers new perspectives on involving older people in co-design and governance of smart health and smart homes.
RESUMO
INTRODUCTION: This protocol describes a study of a quality improvement collaborative (QIC) to support implementation and delivery of comprehensive geriatric assessment (CGA) in UK care homes. The QIC will be formed of health and social care professionals working in and with care homes and will be supported by clinical, quality improvement and research specialists. QIC participants will receive quality improvement training using the Model for Improvement. An appreciative approach to working with care homes will be encouraged through facilitated shared learning events, quality improvement coaching and assistance with project evaluation. METHODS AND ANALYSIS: The QIC will be delivered across a range of partnering organisations which plan, deliver and evaluate health services for care home residents in four local areas of one geographical region. A realist evaluation framework will be used to develop a programme theory informing how QICs are thought to work, for whom and in what ways when used to implement and deliver CGA in care homes. Data collection will involve participant observations of the QIC over 18 months, and interviews/focus groups with QIC participants to iteratively define, refine, test or refute the programme theory. Two researchers will analyse field notes, and interview/focus group transcripts, coding data using inductive and deductive analysis. The key findings and linked programme theory will be summarised as context-mechanism-outcome configurations describing what needs to be in place to use QICs to implement service improvements in care homes. ETHICS AND DISSEMINATION: The study protocol was reviewed by the National Health Service Health Research Authority (London Bromley research ethics committee reference: 205840) and the University of Nottingham (reference: LT07092016) ethics committees. Both determined that the Proactive HEAlthcare of Older People in Care Homes study was a service and quality improvement initiative. Findings will be shared nationally and internationally through conference presentations, publication in peer-reviewed journals, a graphical illustration and a dissemination video.

INTRODUCTION: Care home residents are relatively high users of healthcare resources and may have complex needs. Comprehensive geriatric assessment (CGA) may benefit care home residents and improve efficiency of care delivery. This is an approach to care in which there is a thorough multidisciplinary assessment (physical and mental health, functioning and physical and social environments) and a care plan based on this assessment, usually delivered by a multidisciplinary team. The CGA process is known to improve outcomes for community-dwelling older people and those in receipt of hospital care, but less is known about its efficacy in care home residents. METHODS AND ANALYSIS: Realist review was selected as the most appropriate method to explore the complex nature of the care home setting and multidisciplinary delivery of care. The aim of the realist review is to identify and characterise a programme theory that underpins the CGA intervention. The realist review will extract data from research articles which describe the causal mechanisms through which the practice of CGA generates outcomes. The focus of the intervention is care homes, and the outcomes of interest are health-related quality of life and satisfaction with services; for both residents and staff. Further outcomes may include appropriate use of National Health Service services and resources of older care home residents. The review will proceed through three stages: (1) identifying the candidate programme theories that underpin CGA through interviews with key stakeholders, systematic search of the peer-reviewed and non-peer-reviewed evidence, (2) identifying the evidence relevant to CGA in UK care homes and refining the programme theories through refining and iterating the systematic search, lateral searches and seeking further information from study authors and (3) analysis and synthesis of evidence, involving the testing of the programme theories. ETHICS AND DISSEMINATION: The PEACH project was identified as service development following submission to the UK Health Research Authority and subsequent review by the University of Nottingham Research Ethics Committee. The study protocols have been reviewed as part of good governance by the Nottinghamshire Healthcare Foundation Trust. We aim to publish this realist review in a peer-reviewed journal with international readership. We will disseminate findings to public and stakeholders using knowledge mobilisation techniques. Stakeholders will include the Quality Improvement Collaboratives within PEACH study. National networks, such as British Society of Gerontology and National Care Association will be approached for wider dissemination. TRIAL REGISTRATION NUMBER: The realist review has been registered on International Prospective Register of Systematic Reviews (PROSPERO 2017: CRD42017062601).

Neuropilin-1 (NP1), in conjunction with plexins, promotes axon repulsion by binding to semaphorin 3A (SEMA3A). Although NP1 is expressed in carcinoma cells, its functions have remained elusive, and neither SEMA3A nor plexin expression has been explored in cancer. Here we provide evidence that breast carcinoma cells support an autocrine pathway involving SEMA3A, plexin-A1, and NP1 that impedes their ability to chemotax. Reducing SEMA3A or NP1 expression by RNA interference or inhibiting plexin-A1 signaling enhanced migration. Conversely, expression of constitutively active plexin-A1 impaired chemotaxis. The paradox of how breast carcinoma cells expressing these endogenous chemotaxis inhibitors are able to migrate is explained by their expression of vascular endothelial growth factor (VEGF), a NP1 ligand that competes with SEMA3A for receptor binding. Finally, we establish that the ratio of endogenous VEGF and SEMA3A concentrations in carcinoma cells determines their chemotactic rate. Our findings lead to the surprising conclusion that opposing autocrine loops involving NP1 regulate the chemotaxis of breast carcinoma cells. Moreover, our data indicate a novel autocrine function for VEGF in chemotaxis.

INTRODUCTION: The commissioning of third sector services for older people may influence the quality, availability and coordination of services for older people. The SOPRANO study aims to understand the relationships between and processes of commissioning bodies and third sector organisations providing health and social care services for older people. METHODS AND ANALYSIS: This qualitative study will be based in the East Midlands region of England. An initial scoping survey of commissioners will give an overview of services to maintain the health and well-being of older people in the community that are commissioned. Following this, semistructured interviews will be conducted with 4 sample groups: health and social care commissioners, service provider managers, service provider case workers and older service users. A sample size of 10-15 participants in each of the 4 groups is expected to be sufficient to reach data saturation, resulting in a final expected sample size of 40-60 participants. Informed consent will be gained from all participants, and those unable to provide informed consent will be excluded. The interview data will be analysed by 2 researchers using framework content analysis. ETHICS AND DISSEMINATION: Approval for the study has been gained from the University of Nottingham School of Medicine ethical review board, and the relevant approvals have been gained from the National Health Service (NHS) research and development departments for interviewing NHS staff. Early engagement with a wide range of stakeholders will ensure that the research findings are extensively disseminated to relevant stakeholders (including commissioners and third sector providers) in an accessible format using the extensive communication networks available to the National Institute for Health Research (NIHR) Collaboration for Leadership in Applied Health Research and Care CLAHRCs (applied health research organisations covering all of England). The study will also be disseminated through academic routes such as conference presentations and journal papers.

Distinct changes in glycogen synthase kinase-3 (GSK-3) signalling can regulate neuronal morphogenesis including the determination and maintenance of axonal identity, and are required for neurotrophin-mediated axon elongation. In addition, we have previously shown a dependency on GSK-3 activation in the semaphorin 3A (Sema3A)-mediated growth-cone-collapse response of sensory neurons. Regulation of GSK-3 activity involves the intermediate signalling lipid phosphatidylinositol 3,4,5-trisphosphate, which can be modulated by phosphatidylinositol 3-kinase (PI3K) and the tumour suppressor PTEN. We report here the involvement of PTEN in the Sema3A-mediated growth cone collapse. Sema3A suppresses PI3K signalling concomitant with the activation of GSK-3, which depends on the phosphatase activity of PTEN. PTEN is highly enriched in the axonal compartment and the central domain of sensory growth cones during axonal extension, where it colocalises with microtubules. Following exposure to Sema3A, PTEN accumulates rapidly at the growth cone membrane suggesting a mechanism by which PTEN couples Sema3A signalling to growth cone collapse. These findings demonstrate a dependency on PTEN to regulate GSK-3 signalling in response to Sema3A and highlight the importance of subcellular distributions of PTEN to control growth cone behaviour.
