RESUMO

The Homecare Service was developed as a response to the COVID-19 pandemic, providing all the elements of a mental health inpatient programme remotely, in the comfort and safety of the service user's home thus reducing the need for a physical admission. The aim of this study was to explore service user experiences of a remote virtual inpatient care at an Irish independent mental health service. All participants who had a virtual admission in a 3-month period were invited to complete a series of questions via an online survey. Three open-ended questions generated qualitative data from this mixed methods study, which were thematically analysed. Three themes reflected service user experience: 'The Homecare Service: a viable alternative to inpatient care'; 'Importance of relationships' and 'Technology and Homecare.' Overall, there was general satisfaction with the service. This study provided a good opportunity to identify issues that have emerged considering the prompt implementation of the initiative. Feedback relating to improvements can be implemented in future service delivery.

RESUMO

Ethics is a foundational competency in healthcare inherent in everyday nursing practice. Therefore, the promotion of qualified nurses' and nursing students' moral competence is essential to ensure ethically high-quality and sustainable healthcare. The aim of this integrative literature review is to identify the factors contributing to the promotion of qualified nurses' and nursing students' moral competence. The review has been registered in PROSPERO (CRD42023386947) and reported according to the PRISMA guideline. Focusing on qualified nurses' and nursing students' moral competence, a literature search was undertaken in January 2023 in six scientific databases: CINAHL, Cochrane Library, PsycINFO, PubMed Medline, Scopus and Web of Science. Empirical studies written in English without time limitation were eligible for inclusion. A total of 29 full texts were retrieved and included out of 5233 citations. Quality appraisal was employed using Joanna Briggs Institute checklists and the Mixed Method Appraisal Tool. Data were analysed using inductive content analysis. Research about the factors contributing to the promotion of qualified nurses' and nursing students' moral competence is limited and mainly explored using descriptive research designs. The contributing factors were identified as comprising two main categories: (1) human factors, consisting of four categories: individual, social, managerial and professional factors, and ten sub-categories; and (2) structural factors, consisting of four categories: educational, environmental, organisational and societal factors, and eight sub-categories. This review provides knowledge about the factors contributing to the promotion of qualified nurses' and nursing students' moral competence for the use of researchers, nurse educators, managers, organisations and policymakers. More research about the contributing factors is needed using complex intervention, implementation and multiple methods designs to ensure ethically sustainable healthcare.

RESUMO

BACKGROUND: Muscle mass and strength decrease during short periods of immobilization and slowly recover during remobilization. Recent artificial intelligence applications have identified peptides that appear to possess anabolic properties in in vitro assays and murine models. OBJECTIVES: This study aimed to compare the impact of Vicia faba peptide network compared with milk protein supplementation on muscle mass and strength loss during limb immobilization and regain during remobilization. METHODS: Thirty young (24 ± 5 y) men were subjected to 7 d of one-legged knee immobilization followed by 14 d of ambulant recovery. Participants were randomly allocated to ingest either 10 g of the Vicia faba peptide network (NPN_1; n = 15) or an isonitrogenous control (milk protein concentrate; MPC; n = 15) twice daily throughout the study. Single-slice computed tomography scans were performed to assess quadriceps cross-sectional area (CSA). Deuterium oxide ingestion and muscle biopsy sampling were applied to measure myofibrillar protein synthesis rates. RESULTS: Leg immobilization decreased quadriceps CSA (primary outcome) from 81.9 ± 10.6 to 76.5 ± 9.2 cm2 and from 74.8 ± 10.6 to 71.5 ± 9.8 cm2 in the NPN_1 and MPC groups, respectively (P < 0.001). Remobilization partially recovered quadriceps CSA (77.3 ± 9.3 and 72.6 ± 10.0 cm2, respectively; P = 0.009), with no differences between the groups (P > 0.05). During immobilization, myofibrillar protein synthesis rates (secondary outcome) were lower in the immobilized leg (1.07% ± 0.24% and 1.10% ± 0.24%/d, respectively) than in the non-immobilized leg (1.55% ± 0.27% and 1.52% ± 0.20%/d, respectively; P < 0.001), with no differences between the groups (P > 0.05). During remobilization, myofibrillar protein synthesis rates in the immobilized leg were greater with NPN_1 than those with MPC (1.53% ± 0.38% vs. 1.23% ± 0.36%/d, respectively; P = 0.027). CONCLUSION: NPN_1 supplementation does not differ from milk protein in modulating the loss of muscle size during short-term immobilization and the regain during remobilization in young men. NPN_1 supplementation does not differ from milk protein supplementation in modulating the myofibrillar protein synthesis rates during immobilization but further increases myofibrillar protein synthesis rates during remobilization.

RESUMO

BACKGROUND: The use of psychotropic medication is often the first line of treatment for people with mental distress. However, many service users discontinue their prescribed medication, and little is known about their experiences or the reasons why they choose to stop taking medication. AIM: The aim of this review is to synthesize research literature focused on the experiences of people who decided to discontinue taking medication for their mental health problem. METHODS: A systematic review of qualitative studies was conducted. Data bases were searched for qualitative research which explored participants' motivations for discontinuing medication and their experiences of the process. RESULTS: Six themes were identified: (1) Taking medications: a loss of autonomy, (2) Discontinuing medication: a thought-out process, (3) Factors influencing the decision to discontinue medication, (4) Discontinuing medication: experiences of the process, (5) Outcomes of discontinuing medication, (6) Managing mental distress in the absence of medication. CONCLUSION: Service providers need to be aware that for some service user's psychotropic medication is not deemed a suitable treatment approach. Those who wish to discontinue medication need to be supported in the context of positive, therapeutic risk where their mental and physical health can be monitored and the likelihood of success increased.

RESUMO

Resilience refers to an individual's ability to adapt and bounce back following adversity. As a concept it may help to explain how some people cope with stressors using internal and social support, leading to personal growth. The concept of resilience is frequently mentioned in the literature but often poorly understood. Older people are vulnerable to multiple adversities such as loss and chronic illness and therefore it is important to introduce strategies that promote resilience. The aim of this article is to explore the concept of resilience in older people by using the social ecological model to examine factors that influence resilience within this context. It further discusses the role of the nurse and uses a case study to highlight how nurses can facilitate the use of individual, contextual and sociocultural resources to foster resilience with older people in practice.

RESUMO

Self-management is a key skill that older adults with multiple comorbidities require. Self-management interventions include medication management, self-monitoring and self-awareness and self-management often requires the older adult to manage the emotional consequences of having multiple comorbidities. The benefits of self-management for older adults include reduced reliance on the health system, enhanced quality of life, empowerment of the individual and reduction in the burden associated with chronic illness. Many factors can influence an older adult's ability to self-manage, including health literacy, mental health difficulties and socio-economic factors. Self-management support is the provision of structures, services and programmes to support and enhance the skills of older adults in managing their own conditions. Nurses are in a pivotal position across the continuum of care, using both person-centred care and the 'Making Every Contact Count' approach, to support older adults to self-manage their conditions.

RESUMO

Mental health nursing in the forensic services is perceived as stressful as there is often a tension between therapeutic and custodial processes. Clinical supervision has been discussed as a support strategy for nurses. The aim of this paper is to explore forensic mental health nurses understanding of clinical supervision and their perception of its utility within their practice. A qualitative descriptive method was used and 10 mental health nurses were interviewed with the aid of an interview guide. Qualitative data was analysed using a thematic approach culminating in the emergence of three themes.Participants talked about the tension between caring and custodial roles within the forensic services which was stressful and created difficulties in the maintenance of a therapeutic relationship. Clinical supervision was seen as a necessary support to assist nurses working in the forensic services. The findings support the premise that there is a tension between therapeutic and custodial practices. Acknowledgement of the complexities of working within the forensic services and the provision of clinical supervision within a confidential, non-judgemental relationship may assist nurses in the provision of care and the maintenance of therapeutic relationships.

RESUMO

AIM(S): To report review findings into interventions used to educate the health and social care workforce on the experiences and needs of LGBT+ older adults. BACKGROUND: Research demonstrates that inequalities in outcomes on health and social well-being for LGBT+ older adults are perpetuated by the cumulative disadvantages from discrimination and social exclusion throughout the life course and a lack of culturally competent workforce. METHODS: A systematic search of peer-reviewed papers published before February 2020 was conducted in electronic databases. The search resulted in a screening of 2,509 papers with nine matching the inclusion criteria, which were rated using the MERSQI quality measure. RESULTS: Studies demonstrated some positive outcomes of interventions, especially an increase in knowledge, but less so in skills and attitudes. DISCUSSION: More robust designs such as randomized controlled trials, the use of standardized measures and a focus more on the longitudinal impact of educational interventions could improve the quality of study designs. CONCLUSION(S): Diversification of intervention content and patient and public involvement in the design, delivery and evaluation of educational interventions could improve efforts and have a more sustained impact on LGBT+ ageing inequalities. IMPLICATIONS FOR NURSING MANAGEMENT: Nurse managers have important roles in supporting staff education and ensuring LGBT+ inclusive practice.

RESUMO

BACKGROUND: Little is known about staff's attitudes in Irish acute hospital settings towards people living with dementia and their perceived dementia knowledge. The aim of this study was to understand the general level of dementia knowledge and attitudes towards dementia in different types of hospital staff, as well as to explore the potential influence of previous dementia training and experience (having a family member with dementia) and the potential moderating effects of personal characteristics. This data was required to plan and deliver general and targeted educational interventions to raise awareness of dementia throughout the acute services. METHODS: A cross-sectional survey was carried out among a diverse range of hospital staff (n = 1795) in three urban acute general hospitals in Ireland, including doctors, nurses, healthcare attendants, allied professionals, and general support staff. Participants' perceived dementia knowledge and attitudes were assessed as well as their previous dementia training and experience. To measure participant's attitude towards dementia, the validated Approaches to Dementia Questionnaire (ADQ) was used. RESULTS: Hospital staff demonstrated positive attitudes towards people living with dementia, and believed they had a fair to moderate understanding of dementia. Both 'having previous dementia training' and 'having a relative living with dementia' predicted attitude towards dementia and perceived dementia knowledge. Interestingly, certain personal staff characteristics did impact dementia training in predicting attitude towards dementia and perceived dementia knowledge. CONCLUSION: This study provides a baseline of data regarding the attitudes towards dementia and perceived dementia knowledge for hospital staff in Irish acute hospitals. The results can inform educational initiatives that target different hospital staff, in order to increase awareness and knowledge to improve quality of dementia care in Irish hospitals.

RESUMO

Irish Travellers are a small indigenous minority group with a distinctive lifestyle and culture which sets them apart from the general population. Travellers are vulnerable to significant mental distress which is exacerbated by the social disadvantage that they experience. A Traveller Mental Health Liaison Nurse (TMHLN) was introduced in one health care region in Ireland to provide support for Travellers and increase their access to mental health services. The aim of this paper is to present the findings from an evaluation which explored Travellers access to and reasons for accessing the TMHLN, the interventions provided and their experiences of and perceptions of the role of the TMHLN. A descriptive qualitative approach was used. Ten Travellers who used the service were interviewed. Following data analysis, three themes emerged: factors affecting Traveller mental health; accessing the TMHLN and the Travellers experiences and perceptions of the TMHLN. The participants were extremely positive about the TMHLN and valued the support provided. The findings highlight how the interpersonal skills associated with mental health nursing set against recovery orientated and culturally congruent practices are suitable approaches when working with Travellers.

RESUMO

Health promotion in later life can support healthy ageing and wellbeing. Nurses across the continuum of care have an important role in promoting positive health and wellbeing messages, but they must be cognisant of the need to engage in, modify and tailor health promotion for and with older adults. This article provides an overview of contemporary issues relevant to health promotion and older people, and the role and contribution of nurses.

RESUMO

Family and informal caregivers provide a substantial amount of care and support to people who experience mental health problems. The aim of this study was to explore mental health nurses', students' and service users' perceptions of the knowledge, skills and attitudes that are required by mental health nurses to work with families and carers using a qualitative methodology. Three themes emerged from the data: Knowledge of the family and how mental distress affects the family; working with the family - support and education; and valuing the role of the family. The three themes demonstrate the complexity of preparing mental health nurses to work with families and carers, and the article offers recommendations about how this might be achieved.

RESUMO

PURPOSE: Even though holistic care has been widely discussed in the health care and professional nursing literature, there is no comprehensive definition of it. Therefore, the aim of this article is to present a concept analysis of holistic care which was developed using the hybrid model. METHODS: The hybrid model comprises three phases. In the theoretical phase, characteristics of holistic care were identified through a review of the literature from CINAHL, MEDLINE, PubMed, OVID, and Google Scholar databases. During the fieldwork phase, in-depth interviews were conducted with eight nurses who were purposely selected. Finally, following an analysis of the literature and the qualitative interviews, a theoretical description of the concept of holistic care was extracted. RESULTS: Two main themes were extracted of analytical phase: "Holistic care for offering a comprehensive model for caring" and "holistic care for improving patients' and nurses' conditions." CONCLUSION: By undertaking a conceptual analysis of holistic care, its meaning can be clarified which will encourage nursing educators to include holistic care in nursing syllabi, and consequently facilitate its provision in practice.

RESUMO

The effects of Toll-like receptor (TLR) activation in peripheral cells are well characterized but, although several TLRs are expressed on cells of the brain, the consequences of their activation on neuronal function remain to be fully investigated, particularly in the context of assessing their potential as therapeutic targets in neurodegenerative diseases. Several endogenous TLR ligands have been identified, many of which are soluble factors released from cells exposed to stressors. In addition, amyloid-ß (Aß) the main constituent of the amyloid plaques in Alzheimer's disease (AD), activates TLR2, although it has also been shown to bind to several other receptors. The objective of this study was to determine whether activation of TLR2 played a role in the developing inflammatory changes and Aß accumulation in a mouse model of AD. Wild type and transgenic mice that overexpress amyloid precursor protein and presenilin 1 (APP/PS1 mice) were treated with anti-TLR2 antibody for 7months from the age of 7-14months. We demonstrate that microglial and astroglial activation, as assessed by MHCII, CD68 and GFAP immunoreactivity was decreased in anti-TLR2 antibody-treated compared with control (IgG)-treated mice. This was associated with reduced Aß plaque burden and improved performance in spatial learning. The data suggest that continued TLR2 activation contributes to the developing neuroinflammation and pathology and may be provide a strategy for limiting the progression of AD.

RESUMO

We describe the clinical and neuropathological features of two cases of cerebellar degeneration with selective involvement of the dentate nucleus. Both cases were associated with malignancy, however known paraneoplastic antibodies were absent. Pathological studies at autopsy confirmed T-cell-mediated neuronal destruction in the cerebellum which was strikingly limited to the dentate nucleus in both patients. The occurrence of these pathological features has not been previously described in antibodynegative paraneoplastic disease, but bears similarities to Rasmussen’s encephalitis.

RESUMO

BACKGROUND: Holistic care is a comprehensive model of caring. Previous studies have shown that most nurses do not apply this method. Examining the effective factors in nurses' provision of holistic care can help with enhancing it. Studying these factors from the point of view of nurses will generate real and meaningful concepts and can help to extend this method of caring. MATERIALS AND METHODS: A qualitative study was used to identify effective factors in holistic care provision. Data gathered by interviewing 14 nurses from university hospitals in Iran were analyzed with a conventional qualitative content analysis method and by using MAXQDA (professional software for qualitative and mixed methods data analysis) software. RESULTS: Analysis of data revealed three main themes as effective factors in providing holistic care: The structure of educational system, professional environment, and personality traits. CONCLUSION: Establishing appropriate educational, management systems, and promoting religiousness and encouragement will induce nurses to provide holistic care and ultimately improve the quality of their caring.

RESUMO

Clostridium difficile is the etiological agent of antibiotic-associated diarrhoea (AAD) and pseudomembranous colitis in humans. The role of the surface layer proteins (SLPs) in this disease has not yet been fully explored. The aim of this study was to investigate a role for SLPs in the recognition of C. difficile and the subsequent activation of the immune system. Bone marrow derived dendritic cells (DCs) exposed to SLPs were assessed for production of inflammatory cytokines, expression of cell surface markers and their ability to generate T helper (Th) cell responses. DCs isolated from C3H/HeN and C3H/HeJ mice were used in order to examine whether SLPs are recognised by TLR4. The role of TLR4 in infection was examined in TLR4-deficient mice. SLPs induced maturation of DCs characterised by production of IL-12, TNFα and IL-10 and expression of MHC class II, CD40, CD80 and CD86. Furthermore, SLP-activated DCs generated Th cells producing IFNγ and IL-17. SLPs were unable to activate DCs isolated from TLR4-mutant C3H/HeJ mice and failed to induce a subsequent Th cell response. TLR4⁻/⁻ and Myd88⁻/⁻, but not TRIF⁻/⁻ mice were more susceptible than wild-type mice to C. difficile infection. Furthermore, SLPs activated NFκB, but not IRF3, downstream of TLR4. Our results indicate that SLPs isolated from C. difficile can activate innate and adaptive immunity and that these effects are mediated by TLR4, with TLR4 having a functional role in experimental C. difficile infection. This suggests an important role for SLPs in the recognition of C. difficile by the immune system.

RESUMO

Toll-like receptors (TLRs) are important molecules involved in the activation of innate and subsequent development of adaptive immunity. TLRs are ligated by exogenous ligands from pathogens and by endogenous ligands released in inflammatory diseases. Activation of TLR leads to activation of NF-κB and release of proinflammatory cytokines, such as IL-6 and TNF-α. TLRs play an important role in the pathogenesis of renal diseases. Increased expression of TLRs have been associated with ischemic kidney damage, acute kidney injury, end-stage renal failure, acute renal transplant rejection, and delayed allograft function. OPN301 is a mouse anti-human TLR2 antibody that cross-reacts with mouse TLR2. We show that inhibition of TLR2 promotes graft function in an isograft model of renal transplantation. Recipient mice were treated intravenously with OPN301 before reperfusion of the transplanted kidney that had been subjected to 30 min of cold ischemia. After 5 d, the residual native kidney was removed, and renal transplant function was assessed 24 h later by measurement of blood urea nitrogen. Renal function in both saline- and isotype-treated mice was similar, with significant improvement in OPN301-treated mice (isotype-treated vs. OPN301-treated: 33.9±3.2 vs. 19.8±1.9 µM; P<0.01). The histopathological appearance corresponded with renal functional results. In OPN301-treated recipients, renal structure was well preserved, whereas in the saline-treated group, tubular injury was severe, with marked tubular thinning, epithelial shedding, cast formation and necrosis. Inhibition of TLR2 also leads to a decrease in C3d deposition, although it is unclear whether this is due directly to TLR2 inhibition or a decrease in renal inflammation. This study shows that inhibition of TLR2 with a therapeutic agent (OPN301) provides significant protection from ischemia/reperfusion injury in a model of kidney transplantation.

RESUMO

Celecoxib is a COX-2 inhibitor drug that can be used to reduce the risk of colorectal adenocarcinoma. Glucocorticoids are used in the treatment of inflammatory bowel disease. A limitation to the use of both drug types is that they undergo absorption from the intestinal tract with serious side effects. The prodrug systems introduced here involve forming a nitro-substituted acylsulfonamide group in the case of celecoxib and a nitro-substituted 21-ester for the glucocorticoids. Drug release is triggered by the nitro reductase action of the colonic microflora, liberating a cyclization competent species. The release of the active parent drugs was evaluated in vitro using Clostridium perfringens and epithelial transport through Caco-2 monolayer evaluation was carried out to estimate the absorption properties of the prodrugs compared to the parental drugs.

RESUMO

Iranian male nurses' career-choosing practices have not been well investigated. The aim of this study was to explore the reasons why Iranian male nurses choose nursing as a career. In addition it sought to understand the reasons why they remain in nursing. An exploratory descriptive design, employing a qualitative approach was used. Eighteen semi-structured interviews were conducted and analyzed using content analysis. The analysis culminated in the development of three themes which described the participants' motivations for choosing nursing as a career as well as the factors that influenced their decisions to remain in nursing following qualification. Practical motivations such as job security were important factors in choosing nursing. The most common reason for remaining in nursing was desire to care for others, for God's sake. Factors that influenced their decision to leave mainly centered on the public view to nursing as a feminine discipline. However, the nurses in this study believed that nursing was a profession appropriate for both men and women because of gendered nursing care and preferences of patient in Iran.
