Abstract: The COVID‐19 pandemic created unprecedented demands and additional stress for nurses in mental health settings. There is no prior evidence on nurses' experience of building and maintaining resilience in the context of work during COVID‐19. The aim of this study was to explore the experience and impacts of the COVID‐19 pandemic on the resilience of nurses in mental health settings. Data from semi‐structured interviews with 20 nurses from an Australian mental health service were analysed using reflexive thematic analysis. Four main themes were generated: experiencing significant disruptions making sense of shared chaos having professional commitment and growing through the challenges. Nurses' practice and teamwork were disrupted by COVID‐19 related changes to care models and infection prevention policies. They successfully adjusted by having awareness of self and others' emotions, using mental and emotional self‐regulatory strategies, engaging in self‐care, using ‘bricolage’ to create different ways to provide care, and having mutually supportive relationships. Nurses connected to their sense of purpose and professional commitment to fuel their therapeutic work and sustain care delivery. They experienced personal and professional growth with an increased understanding of their strengths and resilience. In the post‐pandemic period, although the challenges presented by the pandemic have lessened, there are ongoing negative impacts on nurses' wellbeing. To maintain and strengthen their wellbeing and practice, the findings indicate the importance of professional development in emotional regulation skills, and strategies to strengthen self‐care and build collegial relationships in teams. Resilience education can be implemented to support nurses' resilient practice skills.

Abstract: The analysis of biological s les with polarized infrared spectroscopy (p-IR) has long been a widely practiced method for the determination of s le orientation and structural properties. In contrast to earlier works, which employed this method to investigate the fundamental chemistry of biological systems, recent interests are moving toward “real-world” applications for the evaluation and diagnosis of pathological states. This focal point review provides an up-to-date synopsis of the knowledge of biological materials garnered through linearly p-IR on biomolecules, cells, and tissues. An overview of the theory with special consideration to biological s les is provided. Different modalities which can be employed along with their capabilities and limitations are outlined. Furthermore, an in-depth discussion of factors regarding s le preparation, s le properties, and instrumentation, which can affect p-IR analysis is provided. Additionally, attention is drawn to the potential impacts of analysis of biological s les with inherently polarized light sources, such as synchrotron light and quantum cascade lasers. The vast applications of p-IR for the determination of the structure and orientation of biological s les are given. In conclusion, with considerations to emerging instrumentation, findings by other techniques, and the shift of focus toward clinical applications, we speculate on the future directions of this methodology.

Abstract: Mental health nursing work is challenging, and workplace stress can have negative impacts on nurses' well‐being and practice. Resilience is a dynamic process of positive adaptation and recovery from adversity. The aims of this integrative review were to examine and update understandings and perspectives on resilience in mental health nursing research, and to explore and synthesize the state of empirical knowledge on mental health nurse resilience. This is an update of evidence from a previous review published in 2019. Using integrative review methodology, 15 articles were identified from a systematic search (July 2018–June 2022). Data were extracted, analysed with constant comparison method, synthesized narratively and then compared with the findings from the original review. As an update of evidence, mental health nurse resilience was moderate to high across studies, was positively associated with psychological well‐being, post‐traumatic growth, compassion satisfaction and negatively associated with burnout, mental distress and emotional labour. Lack of support and resources from organizations could negatively impact nurses' ability to maintain resilience and manage workplace challenges through internal self‐regulatory processes. A resilience programme improved mental health nurses' awareness of personal resilience levels, self‐confidence, capacity to develop coping skills and professional relationships. Some studies continue to lack contemporary conceptualizations of resilience, and methodological quality varied from high to low. Further qualitative and interventional research is needed to investigate the role of resilience in mental health nursing practice, personal well‐being, workforce sustainability and the ongoing impacts of the COVID‐19 pandemic.

Abstract: Clinical diagnosis of fibrosis is currently reliant on conventional methods. The current “gold standard” for fibrosis diagnosis is histological examination of a biopsy, which is labour intensive and requires extensive s le preparation. Here we show that a portable handheld near‐infrared spectrometer coupled with machine learning algorithms can discriminate between kidney and cardiac fibrosis in a rat model of kidney failure compared to healthy rats without kidney failure. The most significant changes in the spectra of fibrotic tissue included shifts in absorption bands at 1509, 1581, 1689 and 1725 nm attributed to collagen components. The best discrimination of fibrosis was achieved in kidney tissue (AUC=0.962), which showed a higher level of fibrosis compared to cardiac tissue (AUC=0.882). The results show the potential of the NIR spectroscopy to detect and to quantify fibrosis in the heart and kidney that in the future could be applied as an intraoperative surgical tool to guide surgical procedures.

Abstract: Cognitive impairments associated with advanced age involve alterations in the hippoc us that changes with experience throughout life. The hippoc us is critical for cognitive flexibility involved with extinction and reinstatement of conditioned fear. It is widely accepted that regular exercise can be beneficial for hippoc al function. Therefore, we asked whether chronic voluntary exercise in middle-aged mice can improve extinction and/or reinstatement of conditioned fear compared with standard-housing. Eight-month-old male and female C57Bl/6J mice had access to a running wheel or remained in standard-housing until 11 months of age. Alongside control standard-housed young adult (3-month-old) mice, they received tone–footshock pairings, which were subsequently extinguished with tone-alone presentations the next day. Half of the mice then received a reminder in the form of a single footshock. Male and female 11-month-old mice housed in standard conditions exhibited impaired reinstatement compared with young adult mice. However, for males that had access to a running wheel from 8 months of age, the reminder treatment rescued reinstatement ability. This was not observed in females. Additionally, exercise during middle age in both sexes increased expression of brain-derived neurotrophic factor (Bdnf) mRNA in the hippoc us, specifically exon 4 mRNA. These results show that, at least for males, physical exercise is beneficial for reducing age-related decline in cognitive abilities. Despite not affecting reinstatement, exercise also increased Bdnf gene expression in the female hippoc us, which could potentially benefit other forms of hippoc us-dependent cognition.

Abstract: Mental health nurses are exposed frequently to occupational stress and can experience a range of negative impacts on their well‐being and intention to stay in the nursing workforce. Promoting Resilience in Nurses (PRiN) is a strength‐based resilience education programme that incorporates evidence‐based cognitive behavioural and interpersonal approaches with post‐traumatic growth theory. A partially clustered randomized controlled trial at a large public mental health service will be used to examine the effects of PRiN on mental health nurses’ coping self‐efficacy, resilience, well‐being, mental health, emotional regulation, post‐traumatic growth, workplace belonging, and turnover intention as compared to controls. Process evaluations are increasingly used to help understand and interpret trial results for complex interventions. This paper describes the protocol for an embedded mixed methods process evaluation that aims to evaluate the PRiN programme implementation and identify factors that may explain variation in participant outcomes in the trial. Data collection includes a programme participant satisfaction survey a follow‐up semi‐structured interview with selected programme participants a unit/team manager survey on barriers and facilitators to staff recruitment and programme participation and a fidelity checklist completed by programme facilitators. Normalisation Process Theory will be used to inform data analysis and integration. The findings will provide insights into factors that affect programme implementation, particularly in the context of the COVID‐19 pandemic and may help explain differences in participant outcomes. Findings will also inform post‐trial programme sustainability as well as potential future upscale and adaptation for implementation across healthcare settings.
