RESUMO

A large group of keratin genes (n=54 in the human genome) code for intermediate filament (IF)-forming proteins and show differential regulation in epithelial cells and tissues. Keratin expression can be highly informative about the type of epithelial tissue, differentiation status of constituent cells and biological context (e.g. normal versus diseased settings). The foundational principles underlying the use of keratin expression to gain insight about epithelial cells and tissues primarily originated in pioneering studies conducted in the 1980s. The recent emergence of single cell transcriptomics provides an opportunity to revisit these principles and gain new insight into epithelial biology. Re-analysis of single-cell RNAseq data collected from human and mouse skin has confirmed long-held views regarding the quantitative importance and pairwise regulation of specific keratin genes in keratinocytes of surface epithelia. Furthermore, such analyses confirm and extend the notion that changes in keratin gene expression occur gradually as progenitor keratinocytes commit to and undergo differentiation, and challenge the prevailing assumption that specific keratin combinations reflect a mitotic versus a post-mitotic differentiating state. Our findings provide a blueprint for similar analyses in other tissues, and warrant a more nuanced approach in the use of keratin genes as biomarkers in epithelia.

RESUMO

BACKGROUND: Equality, diversity and inclusion initiatives seek to embed the concept of inclusive pedagogy to promote inclusive educational environments. However, no evidence synthesis exists which examines whether and how the concept of inclusive pedagogy is addressed in online simulation-based learning in the undergraduate nursing education literature. AIMS: To map the evidence regarding the adoption of inclusive pedagogy in online simulation-based learning in undergraduate nursing education. DESIGN: A scoping review. METHODS: Data were extracted, synthesized and presented in narrative and table format. DATA SOURCES: A systematic search of five databases and five sources of grey literature was conducted to search literature published between 1st January 2010 to 1st June 2022. RESULTS: Thirty-eight papers published between 2011 and 2022 were included. The results are presented under three identified themes: (1) Learner diversity; (2) Theoretical frameworks promoting equality, diversity and inclusion in online simulation and (3) Online simulation feedback. CONCLUSION: Inclusive pedagogy has not been considered or embedded in its entirety in online simulation in undergraduate nursing education literature. IMPLICATIONS FOR THE PROFESSION AND/OR PATIENT CARE: Utilizing an inclusive pedagogy framework may prove advantageous in generating inclusive teaching approaches to support all students. IMPACT: This review will interest educators and managers that wish to incorporate equality, diversity and inclusion initiatives in nursing education. REPORTING METHOD: This scoping review has adhered to the EQUATOR guidelines: the Preferred Reporting Items for Systematic Reviews and Meta-Analysis extension for Scoping Reviews checklist. PATIENT OR PUBLIC CONTRIBUTION: No Patient or Public Contribution.

RESUMO

BACKGROUND: All healthcare professional education programmes must adopt a systematic approach towards ensuring graduates achieve the competencies required to be an evidence-based practitioner. While a list of competencies for evidence-based practice exist, health care educators continue to struggle with effectively integrating the necessary competencies into existing curricula. The purpose of this project was to develop an open access cross-discipline, learning outcomes framework to support educators in integrating the teaching, learning and assessment required to ensure all graduates of health care professional programmes can achieve the necessary evidence-based practice competencies. METHODS: An interdisciplinary team of health care professional educators and a librarian completed a review of the health professions literature on the teaching and assessment of evidence-based practice. The literature, coupled with the teams' collective experiences in evidence-based education and research, were used to identify relevant teaching, learning and evidence-based competency frameworks to inform the project design. The guide and toolkit for experience-based co-design developed by the National Health Service Institute for Innovation and Improvement was adopted for this study ( Institute for Innovation and Improvement: Experience Based Design: Guide & Tools In. Leeds: NHS; 2009.). A four-step approach involving three online participatory co-design workshops and a national validation workshop was designed. Students (n = 33), faculty (n = 12), and clinical educators (n = 15) participated in formulating and mapping learning outcomes to evidence-based competencies. RESULTS: Through a rigorous, systematic co-design process the Evidenced-based Education Collaborative (EVIBEC) Learning Outcomes Framework was developed. This framework consists of a series of student-centred learning outcomes, aligned to evidence-based practice competencies, classified according to the 5 As of EBP and mapped to the cognitive levels of Bloom's taxonomy. Associated learning activities for each step of EBP are suggested. CONCLUSIONS: A consensus-based, student-centred learning outcomes framework aligned to a contemporary set of EBP core competencies has been developed. The freely accessible EVIBEC framework may support entry level health care professional EBP education, by informing EBP curriculum development and offering the potential for interdisciplinary approaches to and sharing of valuable teaching and learning resources. Co-design proved an effective method in creating and refining this framework.

RESUMO

Having psychological safety embedded in preceptorship relationships facilitates positive interpersonal and educational experiences for students. Psychological safety refers to a student's belief as to whether or not it is safe for them to take interpersonal risks, such as asking questions, sharing an idea for improvement or speaking up to maintain patient safety. Having psychological safety leads to collaboration, positive student learning experiences and effective patient care. This article presents key guidelines for preceptors to provide a psychologically safe learning environment for their students. Guidelines fall under four categories 1) before meeting students, 2) first meeting students, 3) continued relationship with students, and 4) general rules. These guidelines are informed by current literature on psychological safety and preceptorship and the author's clinical expertise in nursing preceptorship. We conceptualise psychological safety in a nursing preceptorship for preceptors to denote the experience of inclusivity, empowerment, and well-being of students within the social, cultural and physical clinical learning environment. A crucial attribute to cultivating a psychologically safe environment involves being an accessible and approachable preceptor.

RESUMO

Integration of human papillomavirus (HPV) genomes into cellular chromatin is common in HPV-associated cancers. Integration is random, and each site is unique depending on how and where the virus integrates. We recently showed that tandemly integrated HPV16 could result in the formation of a super-enhancer-like element that drives transcription of the viral oncogenes. Here, we characterize the chromatin landscape and genomic architecture of this integration locus to elucidate the mechanisms that promoted de novo super-enhancer formation. Using next-generation sequencing and molecular combing/fiber-FISH, we show that ~26 copies of HPV16 are integrated into an intergenic region of chromosome 2p23.2, interspersed with 25 kb of amplified, flanking cellular DNA. This interspersed, co-amplified viral-host pattern is frequent in HPV-associated cancers and here we designate it as Type III integration. An abundant viral-cellular fusion transcript encoding the viral E6/E7 oncogenes is expressed from the integration locus and the chromatin encompassing both the viral enhancer and a region in the adjacent amplified cellular sequences is strongly enriched in the super-enhancer markers H3K27ac and Brd4. Notably, the peak in the amplified cellular sequence corresponds to an epithelial-cell-type specific enhancer. Thus, HPV16 integration generated a super-enhancer-like element composed of tandem interspersed copies of the viral upstream regulatory region and a cellular enhancer, to drive high levels of oncogene expression.

RESUMO

Physiology is a key element of "bioscience" education within pre-registration nursing programs, but there is a lack of clarity on what is included. Physiology and bioscience content and delivery are highly varied across both higher education institutions and the related programs in the United Kingdom (UK). Despite evidence highlighting concerns over nurses' lack of bioscience knowledge and unsafe practice, there is no universally agreed on curriculum with detailed outcomes of minimum levels of knowledge to support nurses in practice and patient care. This study aimed to inform the construction of discipline-specific physiology learning outcomes to clarify relevant physiological topics required in pre-registration nursing. Initially, 360 learning outcomes were identified from various sources. Using a modified Delphi approach, an expert panel from the Bioscience in Nurse Education group reviewed and modified the list to 195 proposed outcomes. These were circulated to universities in the UK who teach nursing (n = 65). Outcomes that had 80% consensus were automatically included in the next round, with others recommended with modification (response rate 22%). The panel reviewed the modifications, and 182 outcomes were circulated in the second questionnaire (response rate 23%), and further panel review resulting in 177 outcomes agreed. These learning outcomes do not suggest how they should be delivered, but gives the basic level required for qualification as a nurse commensurate with the Nursing and Midwifery Council new standards for the "future nurse."

RESUMO

BACKGROUND: Immersive Virtual Reality (iVR) storytelling is a concept that merges ground-breaking virtual reality technology with the traditional art of storytelling. Virtual reality storytelling offers a rare opportunity to present abstract experiences that challenge boundaries, heighten emotions, and convey previously intangible concepts. Scientific research into immersive virtual reality storytelling is still in its infancy, particularly regarding the field of education in Nursing and Midwifery. Therefore, this study set out to investigate the subjective experience of using an immersive virtual reality storytelling experience as an active pedagogy. METHODS: This was an evaluative study incorporating a multimodal approach encompassing a cross-sectional survey and observational study conducted in a large University in Ireland, offering major undergraduate and graduate degree programmes in the fields of Nursing and Midwifery. Students were invited to view the innovative virtual reality storytelling experience "Wonderful You" (BHD Immersive) that tells the story of the first 9 months of a baby's life inside the woman's womb. On completion, students were asked to complete an anonymous survey about their experience. Observational studies were also carried out, examining the student's engagement and interaction with the iVR experience. A combination of statistical and thematic qualitative analysis was employed to interpret the respective summative rating scale and open-ended response questions in the evaluation survey. Data captured from the observations were grouped into categories and analysed capturing key themes. RESULTS: A response rate of 71.2% (n = 94) identified iVR storytelling as a memorable learning experience that triggered students' engagement and motivation to learn. IVR storytelling enabled students to visualise and better understand abstract concepts. Qualitative analysis of narrative responses revealed the positive evaluations of the iVR storytelling experience. Observational studies further revealed students were highly engaged and interacted positively with the iVR storytelling experience. CONCLUSIONS: The full potential of this new medium of iVR storytelling has yet to be seen. However, this study provides an encouraging insight into the positive attributes of iVR storytelling that engages students and creates authentic active learning experiences.

RESUMO

AIMS AND OBJECTIVES: The aim of this discursive paper is to explore the question 'has biological science reconciled mind and body?'. BACKGROUND: This paper has been inspired by the recognition that bioscience has a historical reputation for privileging the body over the mind. The disregard for the mind (emotions and behaviour) cast bioscience within a 'mind-body problem' paradigm. It has also led to inherent limitations in its capacity to contribute to understanding the complex nature of health. DESIGN: This is a discursive paper. METHODS: Literature from the history and sociology of science and psychoneuroimmunology (1975-2015) inform the arguments in this paper. The historical and sociological literature provides the basis for a socio-cultural debate on mind-body considerations in science since the 1970s. The psychoneuroimmunology literature draws on mind-body bioscientific theory as a way to demonstrate how science is reconciling mind and body and advancing its understanding of the interconnections between emotions, behaviour and health. RESULTS: Using sociological and biological evidence, this paper demonstrates how bioscience is embracing and advancing its understanding of mind-body interconnectedness. It does this by demonstrating the emotional and behavioural alterations that are caused by two common phenomena; prolonged, chronic peripheral inflammation and prolonged psychological stress. The evidence and arguments provided has global currency that advances understanding of the inter-relationship between emotions, behaviour and health. CONCLUSIONS: This paper shows how bioscience has reconciled mind and body. In doing so, it has advanced an understanding of science's contribution to the inter-relationship between emotions, behaviour and health. RELEVANCE TO CLINICAL PRACTICE: The biological evidence supporting mind-body science has relevance to clinical practice for nurses and other healthcare professions. This paper discusses how this evidence can inform and enhance clinical practice directly and through research, education and policy.

RESUMO

AIMS AND OBJECTIVES: The aim of this project was to develop an educational package for undergraduate student nurses that would provide them with the theoretical knowledge and clinical judgement skills to care for a patient with a wound. BACKGROUND: Internationally there is concern over the adequacy of preparation of undergraduate nurses for the clinical skill of wound care. Deficits have also been identified in the underpinning biological sciences needed for this skill. Expectations associated with wound management have altered significantly in the last two decades with decision making around wound care coming under the scope of practice of nurses. The treatment and care options for patients with wounds must be based on a sound knowledge of how wounds are formed and healed. If nurses do not have the evidence-based knowledge, it can affect wound healing adversely leading to increased patient suffering, pain and delayed healing. From an organisational perspective, delayed healing will increase the cost of care. DESIGN: This project used constructivism learning theory to provide a framework for the development of a wound care educational package for undergraduate Irish nurses in their penultimate year of training. METHODS: Collaboration was formed with key stake holders. Pertinent curriculum content was mapped. Learning strategies to suit the incoming student learning styles were incorporated into newly developed theoretical content and practical skill sessions. CONCLUSION: The developed educational programme will assist student nurses in their care of patients with wounds. RELEVANCE TO CLINICAL PRACTICE: This study provides a model that can be followed to develop small units of the study to keep abreast of changes in health care delivery and the changing scope of practice of nurses. It also contributes to the debate on the teaching and learning of biosciences as it highlights the depth of biological knowledge required as a basis for good evidence-based nursing care.

RESUMO

BACKGROUND: Patients play a central role in nursing preceptorship relationships, a professional educational relationship between a staff nurse and student nurse that is grounded in providing patient care. Yet the patient experiences and perspectives are largely uncaptured in the literature or represented in current preceptorship education programmes. Furthermore, the lack of student, staff nurse & patient involvement in the design of preceptorship education programmes has been noted. OBJECTIVE: To use a co-design process to develop an innovative educational programme for developing interpersonal and communication skills among nurses who act as preceptors. We sought to (a) clarify experiences and events from all three members involved in a preceptorship relationship (student nurse, preceptor, and patient (SPP) in order to develop a shared understanding of nursing preceptorship relationships and (b) identify the key informational and educational needs recommended by SPP for the educational programme. METHODS: Using the principles and the iterative process of Experienced Based Co Design (EBCD), data was collected from qualitative interviews and used to inform a series of co-design workshops and the co-production of the new educational programme. RESULTS: Twenty-six individuals, including undergraduate student nurses, staff nurses, patients, and a team of nursing, educational and educational technologist experts, contributed to developing a blended learning preceptorship educational programme that consists of three core elements (1) six online reusable learning objects, (2) two role play simulations and (3) a virtual reality storytelling simulated experience. CONCLUSIONS: The EBCD process ensured that the educational programme was developed to meet SPP viewpoints associated with fostering positive interpersonal relationships in a nursing preceptorship. EBCD is a valuable framework for developing human-centred educational resources that combine experiential knowledge (experiences) and scientific knowledge (literature-based knowledge). It facilitated the identification and the development of Interpersonal and Communications skills (IP & C skills) training required within a nursing preceptorship relationship, creating an authentic and memorable learning programme. The structure of EBCD harnesses SPP involvement throughout the research and development process, ensuring transparency and continuity of message, scope, and outcomes.


Nursing preceptorship is a professional educational relationship between a staff nurse and student nurse based on providing patient care. The preceptor is a role model for the student, demonstrating professional roles and practice responsibilities. Furthermore, the preceptor accesses the student's clinical competence, providing valuable feedback, support and guidance. Therefore, an effective preceptor must develop interpersonal, teaching and competency assessment skills. This paper describes a co-design project that involved engaging nursing students, nurses, former patients, and educational and nursing specialists in creating a new nursing preceptorship education programme. The goal was to develop an educational programme that combined scientific evidence with real-life experiences of nursing students, nurses, and patients focusing on developing nurses' interpersonal and communication skills required to be an effective preceptor. Collaborative co-design workshops were held virtually over several months. Activities included one to one interviews, group discussions and feedback on various drafts of the developing educational programme. Participants provided their stories, opinions, and ideas to create an outline of the new programme. The co-design team then collaborated with educational technologists and a virtual reality production company to complete the state-of-the-art innovative educational programme. The programme is now ready to be piloted. It is hoped this new innovative programme that blends both scientific knowledge with real-life experiences will help nurses develop the interpersonal and communication skills required when interacting with students and patients.

RESUMO

AIM: The aim of this systematic scoping review is to examine and synthesise the available literature on developing interpersonal and communication skills in general nursing preceptorship education programmes. BACKGROUND: Highly developed interpersonal and communication skills are an essential component of nursing preceptorship. Preceptors are integral in facilitating, guiding, and developing positive interpersonal relationships between the nursing student (the preceptee), the qualified nurse (the preceptor), and patients. They also have a responsibility to foster and develop preceptees' interpersonal and communication skills and assess and deem preceptees as competent in such skills. Furthermore, preceptors require effective interpersonal and communication skills to carry out key responsibilities of their role, including creating a safe clinical learning environment, teaching, and providing effective feedback. DESIGN: A scoping review was conducted using the methodological framework of Arksey and O'Malley. The PRISMA Extension for Scoping Reviews guided the reporting. METHODS: Five electronic databases were searched for relevant articles in consultation with a librarian, supplemented by hand-searching and internet searches for grey literature. A total of 19,431 potentially relevant articles published between Jan 2000 and August 2021 were retrieved from the initial search, and an additional six articles were obtained from the supplemental search. A total of 146 articles were independently reviewed by two researchers, resulting in 24 articles eligible for inclusion in the review. RESULTS: Several themes were identified in the literature that influenced the development of interpersonal and communication skills in preceptorship education and training programmes, including design and development of programmes, key learning outcomes, pedagogical approaches of preceptorship education and training programmes and interpersonal & communication skills development in preceptorship education and training programmes. Conclusions This review highlighted that research on developing interpersonal and communication skills amongst preceptors is mainly absent from the literature. Further research to address these knowledge gaps is warranted. The results from this review can be used to inform future curriculum design and development of nursing preceptorship education and training programmes.

RESUMO

Background: Education is recognised as a constitutional right, however, access to and participation in higher education can be challenging for some students. This has led to the development of various international and local initiatives promoting inclusion, which has increased student representation from marginalised groups. In order to support growing student diversity, teaching and learning (T&L) strategies must encompass inclusive pedagogical principles. Technological advancements have improved opportunities for online T&L strategies and these are becoming an integral component of curricula in undergraduate nursing programmes. Online simulation-based learning (SBL) has gathered momentum in nursing education over the past twenty years. However, it is unclear from the evidence-base how inclusive this educational approach is, and how it can best support the growing diversity among nursing students. This paper outlines the protocol for a scoping review that aims to systematically and comprehensively map the available published and unpublished literature on inclusive pedagogy in online SBL in undergraduate nursing education.  Methods: The Preferred Reporting Items for Systematic Reviews and Meta-analyses Extension for systematic review protocols (PRISMA-P) guided this protocol. Arksey and O'Malley (2005) six-stage methodology framework, the Joanna Briggs Institute (JBI) guidelines (Peters et al., 2020) and the PRISMA extension for scoping reviews (PRISMA-ScR) will guide the proposed scoping review (Tricco et al., 2018). Conclusion: It is envisaged that this scoping review will give a broad overview of the evidence for inclusive pedagogy in online SBL at this point. The findings of this review will be used to inform future policy and the pedagogical and technological design of online SBL activities and assist nurse educators to meet the current requirement of inclusive practice.

RESUMO

BACKGROUND: Developing evaluative measures that assess clinical reasoning remains a major challenge for nursing education. A thorough understanding of biosciences underpins much of nursing practice and is essential to allow nurses to reason effectively. A gap in clinical reasoning can lead to unintended harm. The Script Concordance test holds promise as a measure of clinical reasoning in the context of uncertainty, situations common in nursing practice. The aim of this study is to develop and validate a test for first year undergraduate nursing students that will evaluate how bioscience knowledge is used to clinically reason. METHODS: An international team, teaching biosciences to undergraduate nurses constructed a test integrating common clinical cases with a series of related test items: diagnostic, investigative and treatment. An expert panel (n = 10) took the test and commented on authenticity/ambiguities/omissions etc. This step is crucial for validity and for scoring of the student test. The test was administered to 47 first year undergraduate nursing students from the author sites. Students rated educational aspects of the tool both quantitatively and qualitatively. Statistical and content analyses inform the findings. FINDINGS: Results indicate that the test is reliable and valid, differentiating between experts and students. Students demonstrated an ability to identify relevant data, link this to their bioscience content and predict outcomes (mean score = 50.78 ± 8.89). However, they lacked confidence in their answers when the scenarios appeared incomplete to them. CONCLUSION: Nursing practice is dependent on a thorough understanding of biosciences and the ability to clinically reason. Script concordance tests can be used to promote both competencies. This method of evaluation goes further than probing factual knowledge. It also explores capacities of data interpretation, critical analysis, and clinical reasoning. Evaluating bioscience knowledge and real-world situations encountered in practice is a unique strength of this test.

RESUMO

After the initial discovery of intermediate filament (IF)-forming proteins in 1968, a decade would elapse before they were revealed to comprise a diverse group of proteins which undergo tissue-, developmental stage-, differentiation-, and context-dependent regulation. Our appreciation for just how large (n = 70), conserved, complex, and dynamic IF genes and proteins are became even sharper upon completion of the human genome project. While there has been extraordinary progress in understanding the multimodal roles of IFs in cells and tissues, even revealing them as direct causative agents in a broad array of human genetic disorders, the link between individual IFs and cell differentiation has remained elusive. Here, we review evidence that demonstrates a role for IFs in lineage determination, cell differentiation, and tissue homeostasis. A major theme in this review is the function of IFs as sensors and transducers of mechanical forces, intersecting microenvironmental cues and fundamental processes through cellular redox balance.

RESUMO

The preceptorship model is an education-focused model for teaching and learning within a clinical environment in nursing. It formulates a professional educational relationship between a staff nurse (preceptor) and student nurse and is based on the provision of providing patient care. Preceptorship is widely acknowledged in the literature as a positive pedagogical approach in clinical nursing education in terms of knowledge and skill acquisition, confidence, and professional socialisation of undergraduate nursing students. However, the literature also widely reports negative interpersonal experiences within this professional educational relationship resulting in negative educational experiences and in some cases, negative patient experiences. Therefore, the authors set out to examine what teaching strategies are being implemented by nurse educators to encourage the development of interpersonal and communication skills in facilitating positive interpersonal relationships between the preceptor, nursing student and patient. This paper outlines the protocol for an exploratory scoping review that aims to systematically and comprehensively map out the available published and unpublished literature on the teaching strategies to develop interpersonal and communication skills in preceptorship education and training programmes. To conduct a systematic and comprehensive scoping review, the review will be guided by the Joanna Briggs Institute and Arksey & O' Malley (2005) six-stage iterative framework, as well as PRISMA-ScR framework guidelines, to ensure the quality of the methodological and reporting approaches to the review. It is anticipated that the results of the scoping review will inform nurse educators on the current educational practices for developing interpersonal and communication skills in preceptorship education and training programmes and identify any educational practices that are worthy of further consideration for future research.

RESUMO

Quality measurement initiatives promote quality improvement in healthcare but can be challenging to implement effectively. This paper presents a Rapid Realist Review (RRR) of published literature on Quality Care-Process Metrics (QCP-M) implementation in nursing and midwifery practice. An RRR informed by RAMESES II standards was conducted as an efficient means to synthesize evidence using an expert panel. The review involved research question development, quality appraisal, data extraction, and evidence synthesis. Six program theories summarised below identify the key characteristics that promote positive outcomes in QCP-M implementation. Program Theory 1: Focuses on the evidence base and accessibility of the QCP-M and their ease of use by nurses and midwives working in busy and complex care environments. Program Theory 2: Examines the influence of external factors on QCP-M implementation. Program Theory 3: Relates to existing cultures and systems within clinical sites. Program Theory 4: Relates to nurses' and midwives' knowledge and beliefs. Program Theory 5: Builds on the staff theme of Programme Theory four, extending the culture of organizational learning, and highlights the meaningful engagement of nurses and midwives in the implementation process as a key characteristic of success. Program Theory 6: Relates to patient needs. The results provide nursing and midwifery policymakers and professionals with evidence-based program theory that can be translated into action-orientated strategies to help guide successful QCP-M implementation.

RESUMO

Concerns have arisen internationally over the competency of student nurses to perform wound care. A global shortage of nursing faculty and clinical practice opportunities is regarded as a contributing factor. Virtual simulation offers a possible solution. The aim of this study was to describe the development and educational evaluation of a virtual patient to supplement undergraduate learning of wound care. The National League for Nursing Jeffries model informed the design of the media. Evaluation of the virtual patient by penultimate year nursing students (n = 148) was conducted using a survey design. Findings are presented from statistical and directed content analyses. Most students rated the educational value of the virtual patient and its support of learning highly. They reported a perceived increase in confidence and ability to meet wound care competency outcomes. The virtual patient also provided students with opportunities to develop their clinical reasoning skills. This study provides evidence that virtual patient simulation is an effective pedagogy to increase clinical competence in wound care. It allows nursing students the opportunity to practice skills and utilise theory repetitively in a safe environment, unhampered by a lack of resources such as clinical placement availability and a declining faculty.

RESUMO

The intermediate filament protein keratin 14 (K14) provides vital structural support in basal keratinocytes of epidermis. Recent studies evidenced a role for K14-dependent disulfide bonding in the organization and dynamics of keratin IFs in skin keratinocytes. Here we report that knock-in mice harboring a cysteine-to-alanine substitution at Krt14's codon 373 (C373A) exhibit alterations in disulfide-bonded K14 species and a barrier defect secondary to enhanced proliferation, faster transit time and altered differentiation in epidermis. A proteomics screen identified 14-3-3 as K14 interacting proteins. Follow-up studies showed that YAP1, a transcriptional effector of Hippo signaling regulated by 14-3-3sigma in skin keratinocytes, shows aberrant subcellular partitioning and function in differentiating Krt14 C373A keratinocytes. Residue C373 in K14, which is conserved in a subset of keratins, is revealed as a novel regulator of keratin organization and YAP function in early differentiating keratinocytes, with an impact on cell mechanics, homeostasis and barrier function in epidermis.

RESUMO

Background: In 2018, the Office of the Nursing and Midwifery Services Director (ONMSD) completed phase one of work which culminated in the development and launch of seven research reports with defined suites of quality care process metrics (QC-Ms) and respective indicators for the practice areas - acute care, midwifery, children's, public health nursing, older persons, mental health and intellectual disability nursing in Ireland. This paper presents a rapid realist review protocol that will systematically review the literature that examines QC-M in practice; what worked, or did not work for whom, in what contexts, to what extent, how and why? Methods : The review will explore if there are benefits of using the QC-Ms and what are the contexts in which these mechanisms are triggered. The essence of this rapid realist review is to ascertain how a change in context generates a particular mechanism that produces specific outcomes. A number of steps will occur including locating existing theories on implementation of quality care metrics, searching the evidence, selecting relevant documents, data extraction, validation of findings, synthesising and refining programme theory. This strategy may help to describe potential consequences resulting from changes in context and their interactions with mechanisms. Initial theories will be refined throughout the process by the local reference panel, comprised of eight key intervention stakeholders, knowledge users such as healthcare professionals and an expert panel. Ethical approval is not required for this rapid realist review. Conclusion: It is anticipated that the final programme theory will help to explain how QC-Ms work in practice; for whom, why and in what circumstances. Findings of this review could help to give insights into realism as a framework and how nursing and midwifery QC-Ms have been implemented previously.

RESUMO

WHAT IS KNOWN ON THE SUBJECT?: Patient and public involvement (PPI) is recognized as an increasingly important feature of healthcare research, education and public policy. In mental health, PPI is increasingly seen as evidence of the further democratization of services, which started with de-institutionalization in the 1960s and the recovery movement in the 1990s. While much is known about learning enablers and learning gains on generic community-based training programmes, less is known about PPI-specific programmes in mental health. WHAT THIS PAPER ADDS TO EXISTING KNOWLEDGE?: Participants at a national training programme to support the engagement of service users, their families and carers in mental health services identified training topics of greatest importance to them and reported on what they learnt and what helped their learning. Patient and public involvement training initiatives aimed at supporting the engagement of service users, their families and carers should emphasize individual needs and local contexts. Training programmes should not make artificial or actual distinctions between the programme participants who are health professionals and those who are non-professionals, such as service users. To our knowledge, this PPI initiative is the first time a national health service provider has sought to develop an engagement structure in mental health on a state-wide basis. WHAT ARE THE IMPLICATIONS FOR PRACTICE?: Participants in training programmes designed to support patient and public involvement believe that such programmes should include understanding how conflict is resolved, how committees work effectively and how to develop interpersonal and facilitation skills. Training programmes in mental health involving both professional and non-professional participants requires all the participants to work together in particular at commissioning and design stages to achieve their desired outcome. The evaluation of the training programme to support the roll-out of this initiative offers lessons to others who may wish to pursue similar structures in other jurisdictions. Abstract Introduction The Irish national mental health service provider commissioned a national training programme to support a patient and public involvement (PPI) initiative in mental health services. The programme evaluation afforded an opportunity to describe the learning gains and learning enablers and the factors that support PPI in mental health. Aim We aimed to evaluate a PPI training programme across nine regional administrative units in a national mental health service. Methods We conducted a participant exit survey, using the Student Assessment of Learning Gains (SALG) instrument. We analysed the survey responses using SPSS version 24 software and applied directed content analysis to the narrative comments provided in open-ended questions. Results A total of 54 participants returned the completed questionnaire, yielding a response rate of 60%. The overall mean SALG score yielded was 3.97 (SD 0.66; range 1-5), indicating that participants reported very good to excellent gains in their learning from the programme. Participants who offered narrative comments indicated an overall positive experience but suggested that all stakeholders should work together to co-produce the training. Discussion All the stakeholders in a PPI training initiative to support the engagement of service users, their families and carers in mental health should work together to achieve their desired outcome. This requires co-production in the design, delivery and evaluation of the training initiative, and co-production can impact at both individual and local levels. Implications for Practice PPI training initiatives in mental health should retain a focus on understanding conflict resolution, committee effectiveness, interpersonal and facilitation skills. Ensuring a shared understanding of key concepts, such as co-production, is a necessary prerequisite at the co-commissioning, co-design, co-planning, co-delivery and co-assessment stages of programme development, as is the need to avoid artificial or actual distinctions between health professionals and those who are non-professionals, such as service users. Relevance statement Mental health engagement and PPI are key principles underpinning modern mental health services and may increasingly impact on wider health service provision including policy and research imperatives. This paper discusses the evaluation of a PPI training programme and offers practical insights as to how such initiatives can be improved.
