RESUMEN

BACKGROUND: Regulation of the thermogenic response by brown adipose tissue (BAT) is an important component of energy homeostasis with implications for the treatment of obesity and diabetes. Our preliminary analyses of RNA-Seq data uncovered many nodes representing epigenetic modifiers that are altered in BAT in response to chronic thermogenic activation. Thus, we hypothesized that chronic thermogenic activation broadly alters epigenetic modifications of DNA and histones in BAT. RESULTS: Motivated to understand how BAT function is regulated epigenetically, we developed a novel method for the first-ever unbiased top-down proteomic quantitation of histone modifications in BAT and validated our results with a multi-omic approach. To test our hypothesis, wildtype male C57BL/6J mice were housed under chronic conditions of thermoneutral temperature (TN, 28°C), mild cold/room temperature (RT, 22°C), or severe cold (SC, 8°C) and BAT was analyzed for DNA methylation and histone modifications. Methylation of promoters and intragenic regions in genomic DNA decrease in response to chronic cold exposure. Integration of DNA methylation and RNA expression datasets suggest a role for epigenetic modification of DNA in regulation of gene expression in response to cold. In response to cold housing, we observe increased bulk acetylation of histones H3.2 and H4, increased histone H3.2 proteoforms with di- and trimethylation of lysine 9 (K9me2 and K9me3), and increased histone H4 proteoforms with acetylation of lysine 16 (K16ac) in BAT. CONCLUSIONS: Our results reveal global epigenetically-regulated transcriptional "on" and "off" signals in murine BAT in response to varying degrees of chronic cold stimuli and establish a novel methodology to quantitatively study histones in BAT, allowing for direct comparisons to decipher mechanistic changes during the thermogenic response. Additionally, we make histone PTM and proteoform quantitation, RNA splicing, RRBS, and transcriptional footprint datasets available as a resource for future research.

RESUMEN

PURPOSE: Mesothelioma is an incurable, asbestos related cancer with a poor prognosis. Little is known about how patients and carers living with the condition manage their mental health and wellbeing needs. This paper reports findings on interventions being used by patients and informal carers living with mesothelioma and those which they find most helpful. METHODS: In-depth interviews with patients (n = 10) and (informal) carers (n = 11) living with mesothelioma in the UK. We analysed our data inductively using a reflexive thematic analysis approach. RESULTS: Participants described the importance of both smaller and larger actions and strategies which helped with their mental health. This included spending more time with family and friends and going on holidays. Professionals who participants said supported their mental health journey included not only specialist nurses and mental health professionals but also legal and Asbestos Support Group professionals. The latter demonstrates the unique needs and support required for this population. Exposure to asbestos as the cause of mesothelioma, has led to a social justice aspect of the experience of living with this cancer. Participants reported the importance of collective action to their mental health and wellbeing. The data indicate that patients and carers may have distinct mental health and wellbeing requirements and need to manage these in different ways at different times. CONCLUSIONS: Findings have implications for nurses and other key professionals working in healthcare, community and legal settings supporting this client group, and for those living with mesothelioma who want to understand ways to enhance their own wellbeing.

RESUMEN

Ending familial co-residence, termed 'moving on' by participants, is an increasingly relevant life transition for people with a learning disability due to increasing life expectancy and policy developments. Nevertheless, there is an absence of research exploring this transition experience in a United Kingdom (UK) context. This constructivist grounded theory study therefore aimed to explore, conceptualise, and theorise the 'moving on' experiences of adults with a learning disability and their families. This article reports the experiences of five adults with a learning disability and nine family members in England, UK. Narrative interviews and creative storybook methods were used to collect data between April 2015 and May 2016. Constant comparative methods, theoretical sampling, and memo writing were used throughout data collection and analysis. Participants with a learning disability presented personal growth and greater life fulfilment over the course of the transition; they flourished. In parallel, family members relinquished their care responsibilities. Importantly, the iterative and reciprocal relationship between flourishing and relinquishing shows that ongoing family member involvement is crucial during and following relocation. Family members identified factors that potentially inhibit relinquishing: pressure to 'let go', different perceptions of independence between family members and service providers, inadequate future investment, and rapport with professional carers. These novel insights led to the generation of the first known mid-range theory concerning this transition, entitled 'Moving on: flourishing and relinquishing'. Findings will guide future research in this field and facilitate the design of appropriate support for people with a learning disability and their families.

RESUMEN

AIM: The aim of this study was to understand the factors that contribute to the development of the nursing associate professional identity. DESIGN: A 3-year longitudinal qualitative study of trainee nursing associates. METHODS: Trainee nursing associates in England were interviewed remotely annually in February 2020, March 2021 and March 2022. They also provided diary entries. Data were anonymised, transcribed and analysed thematically. RESULTS: Nursing associate professional identity was developed through: increased knowledge, skills and responsibility; and self-perceptions of identity alongside responses to the role by colleagues. Tensions arose when the scope of practice expected by organisations differed from that expected by the nursing associates. Frustrations occurred when nursing associates were perceived as substitutes for Registered Nurses in the context of nursing workforce shortages. CONCLUSION: Nursing associates in this study clearly valued their new knowledge, skills and responsibility, enabling them to provide enhanced patient care. Increased clarity of role boundaries is necessary in enhancing the professional identity of nursing associates and reducing inter-professional tensions arising from role ambiguity within health and social care organisations. IMPLICATIONS FOR THE PROFESSION: National guidance and employers should provide clarity on the boundaries of the nursing associate role which will strengthen their professional identity and mitigate role ambiguity within health and social care organisations. REPORTING METHOD: The Consolidated Criteria for Reporting Qualitative Research has been used to guide reporting. PATIENT OF PUBLIC CONTRIBUTION: A patient and public involvement group was consulted during the initial study design stage. IMPACT: This study aimed to understand the factors which contribute to the development of a nursing associate professional identity. Nursing associate professional identity is developed through increased knowledge, skills and responsibility, and the perceptions of identity by participants themselves and their colleagues. The findings should inform the implementation of initiatives to clarify nursing associate role boundaries and the development of similar roles internationally.

RESUMEN

PURPOSE: Mesothelioma is an incurable, asbestos-related cancer with a poor prognosis. There is scant evidence about the mental health and well-being impacts on patients and carers living with the illness. This study aimed to investigate mesothelioma's impact on mental health and well-being and the scale of mental health conditions in patients and informal carers. METHODS: A mixed-methods design was used: a cross-sectional survey of mesothelioma patients and informal carers plus semi-structured interviews with patients and carers. The survey used validated scales collecting data on mental health aspects of mesothelioma: the EQ5D to assess health-related quality-of-life; the Hospital Anxiety and Depression scale; the PCL-5 to assess Posttraumatic Stress; and the Posttraumatic Growth Inventory. The datasets were integrated during analysis. RESULTS: 96 useable survey responses were received. A clinical level of depression was reported by 29 participants (30.21%), of anxiety by 48 (50%), of posttraumatic distress disorder by 32 (33.33%), and of posttraumatic growth by 34 (35.42%). Carers had worse scores than patients. Three main themes were developed from interviews with 10 patients and 11 carers: 'Prognosis', 'Support from services', and 'Social connections and communication'. CONCLUSIONS: Healthcare professionals delivering a mesothelioma diagnosis require regular training in communication skills plus updating in current treatment options, so they provide an appropriate mix of realism and hope. Better signposting to mental health support is needed for patients and carers. Our introduction of posttraumatic growth into the mesothelioma literature is novel. We recommend specialist nurses are trained to recognise, understand, and foster posttraumatic growth.

RESUMEN

In nucleosomes, histone N-terminal tails exist in dynamic equilibrium between free/accessible and collapsed/DNA-bound states. The latter state is expected to impact histone N-termini availability to the epigenetic machinery. Notably, H3 tail acetylation (e.g. K9ac, K14ac, K18ac) is linked to increased H3K4me3 engagement by the BPTF PHD finger, but it is unknown if this mechanism has a broader extension. Here, we show that H3 tail acetylation promotes nucleosomal accessibility to other H3K4 methyl readers, and importantly, extends to H3K4 writers, notably methyltransferase MLL1. This regulation is not observed on peptide substrates yet occurs on the cis H3 tail, as determined with fully-defined heterotypic nucleosomes. In vivo, H3 tail acetylation is directly and dynamically coupled with cis H3K4 methylation levels. Together, these observations reveal an acetylation 'chromatin switch' on the H3 tail that modulates read-write accessibility in nucleosomes and resolves the long-standing question of why H3K4me3 levels are coupled with H3 acetylation.

RESUMEN

BACKGROUND: The nursing associate role was first deployed in England in 2019 to fill a perceived skills gap in the nursing workforce between healthcare assistants and registered nurses and to offer an alternative route into registered nursing. Initially, trainee nursing associates were predominantly based in hospital settings; however, more recently, there has been an increase in trainees based in primary care settings. Early research has focussed on experiences of the role across a range of settings, particularly secondary care; therefore, little is known about the experiences and unique support needs of trainees based in primary care. AIM: To explore the experiences and career development opportunities for trainee nursing associates based in primary care. METHODS: This study used a qualitative exploratory design. Semi-structured interviews were undertaken with 11 trainee nursing associates based in primary care from across England. Data were collected between October and November 2021, transcribed and analysed thematically. FINDINGS: Four key themes relating to primary care trainee experiences of training and development were identified. Firstly, nursing associate training provided a 'valuable opportunity for career progression'. Trainees were frustrated by the 'emphasis on secondary care' in both academic content and placement portfolio requirements. They also experienced 'inconsistency in support' from their managers and assessors and noted a number of 'constraints to their learning opportunities', including the opportunity to progress to become registered nurses. CONCLUSION: This study raises important issues for trainee nursing associates, which may influence the recruitment and retention of the nursing associate workforce in primary care. Educators should consider adjustments to how the curriculum is delivered, including primary care skills and relevant assessments. Employers need to recognise the resource requirements for the programme, in relation to time and support, to avoid undue stress for trainees. Protected learning time should enable trainees to meet the required proficiencies.

RESUMEN

OBJECTIVES: Incidence of mesothelioma worldwide is growing and the UK reports the highest global incidence. Mesothelioma is an incurable cancer with a high symptom burden. However, it is under researched when compared to other cancers. The aim of this exercise was to identify unanswered questions about the mesothelioma patient and carer experience in the UK and to prioritise research areas of most importance through consultation with patients, carers and professionals. MATERIALS AND METHODS: A virtual Research Prioritisation Exercise was conducted. This involved a review of mesothelioma patient and carer experience literature to identify research gaps and a national online survey to identify and rank research gaps. Following this, a modified consensus method with mesothelioma experts (patients, carers and professionals from healthcare, legal, academic and volunteer organisations) was undertaken to reach a consensus regarding mesothelioma patient and carer experience research priorities. RESULTS: Survey responses were received from 150 patients, carers and professionals and 29 research priorities were identified. During consensus meetings, 16 experts refined these into a list of 11 key priorities. The five most urgent priorities were symptom management, receiving a mesothelioma diagnosis, palliative and end of life care, treatment experiences, barriers and facilitators to joined up service provision. CONCLUSION: This novel priority setting exercise will shape the national research agenda, contribute knowledge to inform nursing and wider clinical practice and ultimately improve the experiences of mesothelioma patients and carers.

RESUMEN

Histone proteins are essential to the regulation of the eukaryotic genome. Histone post-translational modifications (PTMs) and single-molecule combinations of these modifications (proteoforms) allow for the regulation of many DNA-templated processes, most notably transcription. Histone H4 is a part of the core histone octamer, which packages DNA into nucleosomes. Top-down proteomics allows for the inquiry of the epigenetic landscape with proteoform-level specificity. Although these approaches are well-demonstrated ex vivo, our knowledge of in vivo histone proteoform biology remains sparse. Here, we demonstrate the first in vivo quantitative top-down analysis of histone H4 and analyze the forebrains and hindbrains of differently aged mice. This reveals novel differences between the mouse forebrain and hindbrain and region-specific changes during adolescence in histone H4 PTMs and proteoforms. At 25 days of age (P25), histone H4 of the hindbrain is more acetylated than the forebrain. At 47 days of age (P47), there are fewer significant differences in histone H4 PTMs and their combinations between regions. Histone H4 of the forebrain is more acetylated in P47 than in P25 forebrains. Hindbrains exhibit the opposite difference with histone H4 of the P25 hindbrain being more acetylated than that of P47 hindbrains. These differences are mainly driven by less abundant hyperacetylated proteoforms. Transcription of histone acetyltransferases such as p300, CBP, and HAT1 is known to be higher in cortical neurons, consistent with the observed acetylation levels. Lysine 20 methylation (K20me1, K20me2, and K20me3) is notably invariant with brain region and age difference.

RESUMEN

AIM: To explore higher education institution (HEI) perspectives on the development and implementation of trainee nursing associates (NAs) in the primary care workforce in England. BACKGROUND: Current shortages of primary health care staff have led to innovative skill mix approaches in attempts to maintain safe and effective care. In England, a new level of nursing practice, NAs, was introduced and joined the workforce in 2019. This role was envisaged as a way of bridging the skills gap between health care assistants and registered nurses and as an alternative route into registered nursing. However, there is limited evidence on programme development and implementation of trainee NAs within primary care settings and HEI perspectives on this. METHODS: This paper draws from a larger qualitative study of HEI perspectives on the trainee NA programme. Twenty-seven staff involved in training NAs, from five HEIs across England, were interviewed from June to September 2021. The interview schedule specifically included questions relating to primary care. Data relating to primary care were extracted and analysed using a combined framework and thematic analysis approach. FINDINGS: Three themes were developed: 'Understanding the trainee role and requirements', 'Trainee support in primary care' and 'Skills and scope of practice'. It is apparent that a more limited understanding of the NA programme requirements can lead to difficulties in accessing the right support for trainees in primary care. This can create challenges for trainees in gaining the required competencies and uncertainty in understanding what constitutes a safe scope of practice within the role for both employers and trainees. It might be anticipated that as this new programme becomes more embedded in primary care, a greater understanding will develop, support will improve and the nature and scope of this new level of practice will become clearer.

RESUMEN

PurposeThis article is an in-depth review of the complex classification, diagnosis, and treatment of idiopathic interstitial pneumonias (IIP), as well as emergence of new treatment options. Summary: Idiopathic interstitial pneumonias consist of various subgroup classifications that require expert analysis of imaging and histology to accurately diagnose this broad group of patients. Timely and accurate assessment of these patients is key in developing an appropriate pharmacological plan. The pathophysiology of IIP is not well understood but has been linked to an immune response resulting in inflammation, fibrosis, or proliferation of lung tissue which reduces lung function. Lung transplantation is currently the only curative option for treatment, but many new antiproliferative and immunosuppressive agents are being used to effectively slow the progression of lung dysfunction. Conclusion: An often mixed radiological and histological pattern along with the invasive nature of biopsy for gold standard diagnosis create a challenge for the accurate identification of IIP. Further understanding of these idiopathic interstitial pneumonias will pave the way forward to the emergence of new treatment options and updates to standards of care.

RESUMEN

PURPOSE: The covid-19 global pandemic has impacted on nurses who have rapidly adapted to new ways of working, and experienced negative impacts due to over-stretched services. Two surveys captured the experiences of lung cancer and mesothelioma specialist nurses in the United Kingdom (UK) in 2020, but the impact of later stages of the pandemic was unknown. This study aimed to explore the impact of covid-19 on lung Cancer and mesothelioma nurses since January 2021, the second wave of the pandemic. METHODS: An online cross-sectional survey with both open and closed questions explored the impact of covid-19 on ways of working and workload, quality of care, and health and wellbeing. The survey was open to UK based lung cancer and mesothelioma advanced or specialist nurses. RESULTS: 85 nurses responded to the survey. The majority were Clinical Nurse Specialists, based in England. Respondents reported changes in ways of working due to redeployment, staff shortages, and home working. Widespread adoption of virtual working practices led to concerns of negative impacts. Perceived excessive workload impacted on care with two-thirds of the sample (57, 67%) reporting they had been unable to provide the same quality of care to patients. Impacts on nurses' health and wellbeing were reported with two-thirds of the sample (56, 66%) reporting a deterioration in emotional wellbeing and mental health. Coping mechanisms employed included online team support to share experiences and increased uptake of exercise; however, impacts on lifestyle and access to coping mechanisms varied. CONCLUSION: Nurses have stepped up to the challenges of the pandemic with teamwork and innovation, but pressure arising from the pandemic and high workloads led to negative impacts on wellbeing. The authors have provided recommendations to improve patient care and support the wellbeing of nurses, which will be key to a resilient workforce living with covid-19. Whilst this study focussed on lung cancer and mesothelioma specialists, the findings have wider implications for other cancer specialties.

RESUMEN

BACKGROUND: Moral distress arises when a person is aware of the right course to take but is prevented from acting on it by institutional constraints. While this concept has been considered by nursing ethicists for many years, it has been particularly associated with the unprecedented healthcare conditions caused by the coronavirus disease 2019 (COVID-19) pandemic. AIM: To investigate the level of moral distress affecting advanced practice nurses (APNs) in the UK during the COVID-19 pandemic. METHOD: This was a mixed-methods study in which a bespoke cross-sectional survey was sent to 243 APNs from across the UK who had been recruited to a broader longitudinal cohort study. The survey asked about their experiences, well-being and moral distress. Open-ended questions asked about their concerns regarding the health and well-being of their patients and colleagues. FINDINGS: A total of 97 APNs completed the survey, yielding a 40% response rate. Levels of moral distress were significantly higher among APNs working in secondary care (P=0.026) compared with those working in primary care. All of the respondents expressed concerns about patients due to delayed care and about the mental well-being of their colleagues, particularly those who were redeployed to COVID-19 wards. CONCLUSION: The COVID-19 pandemic has caused moral and psychological distress for APNs. However, the type of distress and its direct causes varied among these practitioners. Tailored support is required to address moral distress and subsequently improve staff retention.

RESUMEN

AIM: The nursing associate role has created a new second-level nursing role and provided an alternative route into registered nursing. For some, this provides a previously inaccessible opportunity for career progression. The aim of the study was to understand the factors that influence career choices of trainee nursing associates. DESIGN: A longitudinal qualitative study of trainee nursing associate motivations, experiences and career aspirations. METHODS: Semi-structured interviews with trainee nursing associates from across England, UK, in February 2020 (N = 14) and March 2021 (N = 13). Diary data were also collected. Interview and diary data were analysed thematically. Reporting has followed COREQ guidelines. RESULTS: Nursing associate training was viewed by some as a bridge into registered nursing. Role ambiguity led several to seek perceived security offered by the Registered Nurse profession. Those preferring to remain as nursing associates were keen to embed the bridging role between healthcare assistants and Registered Nurses, valuing a positive workplace culture.

RESUMEN

Epigenetic variation plays a significant role in normal development and human diseases including cancer, in part through post-translational modifications (PTMs) of histones. Identification and profiling of changes in histone PTMs, and in proteins regulating PTMs, are crucial to understanding diseases, and for discovery of epigenetic therapeutic agents. In this study, we have adapted and validated an antibody-based reverse phase protein array (RPPA) platform for profiling 20 histone PTMs and expression of 40 proteins that modify histones and other epigenomic regulators. The specificity of the RPPA assay for histone PTMs was validated with synthetic peptides corresponding to histone PTMs and by detection of histone PTM changes in response to inhibitors of histone modifier proteins in cell cultures. The useful application of the RPPA platform was demonstrated with two models: induction of pluripotent stem cells and a mouse mammary tumor progression model. Described here is a robust platform that includes a rapid microscale method for histone isolation and partially automated workflows for analysis of histone PTMs and histone modifiers that can be performed in a high-throughput manner with hundreds of samples. This RPPA platform has potential for translational applications through the discovery and validation of epigenetic states as therapeutic targets and biomarkers. SIGNIFICANCE: Our study has established an antibody-based reverse phase protein array platform for global profiling of a wide range of post-translational modifications of histones and histone modifier proteins. The high-throughput platform provides comprehensive analyses of epigenetics for biological research and disease studies and may serve as screening assay for diagnostic purpose or therapy development.

RESUMEN

PURPOSE: Mesothelioma is a rare and incurable cancer linked to asbestos exposure. It primarily affects the pleura. This systematic rapid review aimed to identify what is known about the experience of living with mesothelioma, from the perspective of patients and their informal carers. METHODS: Medline, PsycInfo, Scopus and the Cumulative Index to Nursing and Allied Health Literature were searched for empirical studies published between December 2008 and October 2020. Google Scholar was searched. The inclusion criteria stated that studies were peer-reviewed, reported the experience of living with mesothelioma from the perspective of patients and carers and written in English. The Mixed-Methods Appraisal Tool was used to assess quality. The review protocol is registered on PROSPERO: CRD42020204726. RESULTS: Twenty-five studies met the inclusion criteria. Following data extraction, a narrative synthesis identified three themes: the impact on the individual; the impact on informal carers and relationships; and interactions with professionals and systems. The physical and psychological symptom burden of mesothelioma on patients' lives was reported as high. Both the qualitative and quantitative literature highlighted that patients and carers may have different needs throughout the mesothelioma journey. Differences included psychological experiences and preferences regarding the timing of information and support provision. Patients and carers expected their health care professionals to be knowledgeable about mesothelioma or refer to those who were. Health care professionals that were compassionate, honest and supportive also positively influenced the experience of patients and carers living with mesothelioma. A lack of communication or misinformation was damaging to the patient-healthcare professional relationship. Continuity of care, coordinated care and good communication between treatment centres were widely reported as important in the literature. Fragmented care was identified as detrimental to the patient experience, increasing anxiety in patients. However, relationships with professionals were not only important in terms of co-ordinating care. There was also evidence that good relationships with healthcare professionals were beneficial to coping with the mesothelioma diagnosis. CONCLUSION: The volume of mesothelioma experience research has grown over the past decade. This has led to our growing understanding of the complex needs and experiences of mesothelioma patients and carers. However, this review identified several evidence gaps.

RESUMEN

AIM: To explore how the COVID-19 pandemic affected nursing associate work, training and well-being experiences. DESIGN: Cross-sectional survey. METHODS: A survey of trainee and newly qualified nursing associates was completed in July 2020. Closed responses were analysed using descriptive statistics with inferential comparisons made between community and secondary care settings. Open questions were analysed thematically. RESULTS: Sixty-four participants responded. Over half (53.2%) experienced an increased workload with 24.2% reporting extensions in their role. One third (32.3%) were redeployed, and a quarter (24.2%) did not feel safety concerns were adequately addressed when raised. Those working in the community reported significantly more concerns about staffing (p = .03), working overtime (p = .03), missed care (p = .02) and safety (p = .04). Despite this, many (75.8%) participants felt able to provide the same standards of care. Several spoke about enhanced teamwork, and the majority (96.8%) were not looking to leave their post.

RESUMEN

AIM: This article describes the development and implementation of a virtual Consensus development project to address current challenges in adult nursing care in the UK. DESIGN: This is a Consensus Development Project (CDP). METHODS: The five stages of this CDP were: develop questions (informed by PPI representatives and a documentary review), generate evidence reviews, recruit and orient the lay panel, host Consensus seminars, and consult with panel members and stakeholders. RESULTS: To the best of our knowledge, a CDP has not previously been conducted in a UK nursing context, and this is the first of its kind to be hosted virtually. This article contributes a detailed outline of the Consensus development methodology and constructive commentary to support future Consensus development projects. Learning points include reflections on the impact of hosting this event virtually, the relationship between the project coordinator and chair, and the composition of the lay panel.
