    Purpose This paper aims to provide an evidence assessment and narrative synthesis of literature regarding the key characteristics of older people living in service-integrated housing (SIH) facilities and their “accommodation journey”. Design/methodology/approach A rapid evidence assessment was conducted: 22 research publications met the inclusion criteria and were analysed using narrative synthesis. Findings The quality of studies in this area is low, but consistency across components of the results of studies included in the review is apparent. Results suggest key characteristics of older people that drive moves into SIH are a decline in health, increased dependency, increased health service use and carer burden. Suggested key characteristics of SIH residents are high levels of health problems, dependency and health service use, but high self-reported health and well-being. Results indicate that the key driver for older people leaving SIH is a lack of workforce competency to manage further declines in health and dependency status. Research limitations/implications Current policy may not realise or account for the complex health and care needs of SIH residents. Investment into integrated care, robust community health services and workforce development to facilitate a comprehensive assessment approach may be required to support residents to remain in SIH and live well. Further longitudinal studies are required to map the progression of SIH residents’ health status in detail over time to provide an understanding of preventative and enablement support, development of care pathways and workforce planning and development requirements. Originality/value This evidence assessment is the first to consider the accommodation journey of older people residing in SIH

    VOICE–Validating Outcomes by Including Consumer Experience: A Study Protocol to Develop a Patient Reported Experience Measure for Aboriginal and Torres Strait Islander Peoples Accessing Primary Health Care

    Aboriginal and Torres Strait Islander peoples’ (hereafter respectfully referred to as Indigenous Australians) experiences of health care are shaped by historical, social and cultural factors, with cultural security critical to effective care provision and engagement between services and community. Positive patient experiences are associated with better health outcomes. Consequently, it is an accreditation requirement that primary health care (PHC) services must formally gather and respond to patient feedback. However, currently available patient feedback tools were not developed with Indigenous Australians, and do not reflect their values and world views. Existing tools do not capture important experiences of care of Indigenous Australians in PHC settings, nor return information that assists services to improve care. Consistent with the principles of Indigenous Data Sovereignty, we will co-design and validate an Indigenous-specific Patient Reported Experience Measure (PREM) that produces data by and for community, suitable for use in quality improvement in comprehensive PHC services. This paper presents the protocol of the study, outlining the rationale, methodologies and associated activities that are being applied in developing the PREM. Briefly, guided by an Aboriginal and Torres Strait Islander Advisory Group, our team of Indigenous and non-Indigenous researchers, service providers and policy makers will use a combination of Indigenous methodologies, participatory, and traditional western techniques for scale development. We will engage PHC service staff and communities in eight selected sites across remote, regional, and metropolitan communities in Australia for iterative cycles of data collection and feedback throughout the research process. Yarning Circles with community members will identify core concepts to develop an “Experience of Care Framework”, which will be used to develop items for the PREM. Staff members will be interviewed regarding desirable characteristics and feasibility considerations for the PREM. The PREM will undergo cognitive and psychometric testing

    Antioxidant and lipid supplementation improve the development of photoreceptor outer segments in pluripotent stem cell-derived retinal organoids

    The generation of retinal organoids from human pluripotent stem cells (hPSC) is now a well-established process that in part recapitulates retinal development. However, hPSC-derived photoreceptors that exhibit well-organized outer segment structures have yet to be observed. To facilitate improved inherited retinal disease modeling, we determined conditions that would support outer segment development in maturing hPSC-derived photoreceptors. We established that the use of antioxidants and BSA-bound fatty acids promotes the formation of membranous outer segment-like structures. Using new protocols for hPSC-derived retinal organoid culture, we demonstrated improved outer segment formation for both rod and cone photoreceptors, including organized stacked discs. Using these enhanced conditions to generate iPSC-derived retinal organoids from patients with X-linked retinitis pigmentosa, we established robust cellular phenotypes that could be ameliorated following adeno-associated viral vector-mediated gene augmentation. These findings should aid both disease modeling and the development of therapeutic approaches for the treatment of photoreceptor disorders

    Recapitulation of Human Retinal Development from Human Pluripotent Stem Cells Generates Transplantable Populations of Cone Photoreceptors

    Transplantation of rod photoreceptors, derived either from neonatal retinae or pluripotent stem cells (PSCs), can restore rod-mediated visual function in murine models of inherited blindness. However, humans depend more upon cone photoreceptors that are required for daylight, color, and high-acuity vision. Indeed, macular retinopathies involving loss of cones are leading causes of blindness. An essential step for developing stem cell-based therapies for maculopathies is the ability to generate transplantable human cones from renewable sources. Here, we report a modified 2D/3D protocol for generating hPSC-derived neural retinal vesicles with well-formed ONL-like structures containing cones and rods bearing inner segments and connecting cilia, nascent outer segments, and presynaptic structures. This differentiation system recapitulates human photoreceptor development, allowing the isolation and transplantation of a pure population of stage-matched cones. Purified human long/medium cones survive and become incorporated within the adult mouse retina, supporting the potential of photoreceptor transplantation for treating retinal degeneration

    The Tight Junction Associated Signalling Proteins ZO-1 and ZONAB Regulate Retinal Pigment Epithelium Homeostasis in Mice

    Cell-cell adhesion regulates the development and function of epithelia by providing mechanical support and by guiding cell proliferation and differentiation. The tight junction (TJ) protein zonula occludens (ZO)-1 regulates cell proliferation and gene expression by inhibiting the activity of the Y-box transcription factor ZONAB in cultured epithelial cells. We investigated the role of this TJ-associated signalling pathway in the retinal pigment epithelium (RPE) in vivo by lentivirally-mediated overexpression of ZONAB, and knockdown of its cellular inhibitor ZO-1. Both overexpression of ZONAB or knockdown of ZO-1 resulted in increased RPE proliferation, and induced ultrastructural changes of an epithelial-mesenchymal transition (EMT)-like phenotype. Electron microscopy analysis revealed that transduced RPE monolayers were disorganised with increased pyknosis and monolayer breaks, correlating with increased expression of several EMT markers. Moreover, fluorescein angiography analysis demonstrated that the increased proliferation and EMT-like phenotype induced by overexpression of ZONAB or downregulation of ZO-1 resulted in RPE dysfunction. These findings demonstrate that ZO-1 and ZONAB are critical for differentiation and homeostasis of the RPE monolayer and may be involved in RPE disorders such as proliferative vitroretinopathy and atrophic age-related macular degeneration

    Has Motivational Interviewing fallen into its own Premature Focus Trap?

    Get PDF
    Since the initial conception of the behaviour change method Motivational Interviewing, there has been a shift evident in epistemological, methodological and practical applications, from an inductive, process and practitioner-focussed approach to that which is more deductive, research-outcome, and confirmatory-focussed. This paper highlights the conceptual and practical problems of adopting this approach, including the consequences of assessing the what (deductive outcome-focussed) at the expense of the how (inductively process-focussed). We encourage a return to an inductive, practitioner and client-focussed MI approach and propose the use of Computer Assisted Qualitative Data Analysis Systems such as NVivo in research initiatives to support this aim

    Pharmacokinetic aspects of retinal drug delivery

    Get PDF
    Drug delivery to the posterior eye segment is an important challenge in ophthalmology, because many diseases affect the retina and choroid leading to impaired vision or blindness. Currently, intravitreal injections are the method of choice to administer drugs to the retina, but this approach is applicable only in selected cases (e.g. anti-VEGF antibodies and soluble receptors). There are two basic approaches that can be adopted to improve retinal drug delivery: prolonged and/or retina targeted delivery of intravitreal drugs and use of other routes of drug administration, such as periocular, suprachoroidal, sub-retinal, systemic, or topical. Properties of the administration route, drug and delivery system determine the efficacy and safety of these approaches. Pharmacokinetic and pharmacodynamic factors determine the required dosing rates and doses that are needed for drug action. In addition, tolerability factors limit the use of many materials in ocular drug delivery. This review article provides a critical discussion of retinal drug delivery, particularly from the pharmacokinetic point of view. This article does not include an extensive review of drug delivery technologies, because they have already been reviewed several times recently. Instead, we aim to provide a systematic and quantitative view on the pharmacokinetic factors in drug delivery to the posterior eye segment. This review is based on the literature and unpublished data from the authors' laboratory.Peer reviewe

    A prospective evaluation of involuntary admission from the viewpoint of service users

    Introduction: Involuntary admission is often a traumatic experience for patients and it is associated with negative attitudes which can persist after the episode of illness has abated. Aims: The aims of the study were to prospectively assess attitudes to care and treatment both at involuntary admission and when the individual had recovered to their baseline and to identify clinical predictors of attitudes. Methods Consecutively admitted involuntary patients across three psychiatric admission units were invited to participate in the study. Comprehensive assessments of attitudes and a range of clinical measures, including symptoms, functioning, insight and care experiences, were obtained at admission and 3 months after discharge. Attitudes were assessed using the Client Assessment of Treatment scale (CAT) and a study specific Attitudes Scale to capture aspects of care and treatment specific to involuntary admission. Multiple linear regression modelling was used to identify the optimal explanatory variables for attitudes towards care during acute admission and at the point of recovery to baseline. Results: Two hundred and sixty three individual presentations were included at baseline and onehundred and fifty six (59%) also completed follow-up assessments. Individuals improved significantly over time both clinically and in their attitudes to their involuntary admission and treatment. At follow-up, 65.3% stated that they believed that their involuntary admission was necessary. A multiple linear main effects regression model demonstrated that at baseline having greater awareness of illness (b = 0.041, p < 0.001), being older (b = 0.009, p = 0.003), having had fewer numbers of previous involuntary admissions (b = -0.036, p = 0.001), not having a lifetime history of illicit substance abuse (b = -0.247, p = 0.048) and having a history of lifetime alcohol abuse (b = 0.249, p = 0.015) was associated with more positive attitudes towards involuntary admission and care, adjusting for multiple other factors. Furthermore greater awareness of illness at baseline (b = 0.042, p = 0.006), male gender (b = -0.280, p = 0.045), not having a history of illicit drug use (b = -0.443, p = 0.012), being older (b = 0.012, p = 0.014) and having a diagnosis of a non psychotic illness (b = 0.653, p = 0.050) were 7 associated with more positive attitudes towards involuntary treatment and care at follow up. Over time having a greater improvement in awareness of illness (b = 0.022, p < 0.001), male gender (b = -0.281, p = 0.014) as well as having a diagnosis of a non psychotic illness (b = 0.732, p = 0.009) was associated with more positive attitudes to involuntary treatment and care. There was no significant association between experiencing coercive practices such as seclusion, restraint or forced intramuscular medication and attitudes towards care. Conclusion: At the point of recovery most patients considered their involuntary admission as necessary at the time. Positive attitudes towards involuntary admission and care both at the point of acute admission and at recovery are better predicted by factors related to the illness and its treatability, such as awareness of illness and level of symptoms, than factors related to the service received or extent of coercion employed. Patients who are likely to have persistently negative attitudes to their care could be identified during the admission phase by their clinical characteristics and potentially targeted with additional support to ameliorate their negative experiences
