    This study aimed to develop in-depth understanding of the specific factors in practice placements that influenced student mental health nurse socialisation in compassionate practice. As per the underpinning constructivist research paradigm and case study methodology, multiple sources of data were accessed through two phases of data collection. Phase one, utilised student mental health nurse focus groups. Phase two of the study; a single site case study of an area recommended by student nurses as facilitating their socialisation in compassionate mental health nursing practice, utilised triangulation of placement observations and semi-structured individual interviews with students, and case study site team staff during case study site access. A grounded theory approach to data analysis was implemented to enhance the robust analysis of data gathered. Findings from phase one focus groups, presents two overarching themes uncovered in the data: “All in this together” and “Everyone for themselves”. “All in this together” contains eight themes of student experiences in practice placements that supported student socialisation in compassionate nursing practice. The experiences resulted in students undergoing an opening up to compassion, in which they were able to internalise the value of engagement in compassionate practice as a giver of compassion. Students experienced a journey of socialisation in compassion from a recipient to a giver. The journey was underpinned by a sense of having permission to engage in compassionate practice. The eight themes explored under “Everyone for themselves” were the antithesis of the themes of “All in this together”. The experiences of “Everyone for themselves” resulted in students undergoing a closing down to both the desire to be compassionate, and the scope for them to engage in compassionate practice. Students became introspective and abandoned their compassionate ideals to focus on self-protection and self-preservation. Findings from the phase two case study, present the characteristics of the case and explores the factors that facilitated student socialisation in compassionate mental health nursing 3 practice. These were captured in the overarching themes “That’s what makes it such an amazing placement” and “It makes us what we are”. These themes identified specific factors present that supported the creation and sustainment of the team’s ability to positively socialise students in compassionate mental health nursing practice. Key findings are discussed in relation to A New Grounded Theory of Student Nurse Socialisation in Compassionate Practice (Curtis, 2015) and The Senses Framework (Nolan et al, 2006; Brown, 2005). The impact of leadership on a practice teams’ ability to sustain the factors required to positively socialise students in compassionate mental health nursing practice is also discussed. Recommendations are made for practice, education, policy and research to support our student nurses of today to become compassionate mental health nurses of tomorrow

    Chemistry for the Masses

    Students in a second year Chemical Biology course at a major Australian research university have participated in a "Chemistry for the Masses" assignment as part of their course assessment. The assignment requires students to communicate scientific concepts to a general audience, which is not common for assessment within a Science course. This article describes the assignment components and reflects on the challenges of preparing students for such an assignment. It will be useful to instructors considering similar assessment in their own science courses

    BACKGROUND: Biologically-based models that utilize 3D radiation dosimetry data to estimate the risk of late cardiac effects could have significant utility for planning radiotherapy in young patients. A major challenge arises from having only 2D treatment planning data for patients with long-term follow-up. In this study, we evaluate the accuracy of an advanced deformable image registration (DIR) and navigator channels (NC) adaptation technique to reconstruct 3D heart volumes from 2D radiotherapy planning images for Hodgkin's Lymphoma (HL) patients. METHODS: Planning CT images were obtained for 50 HL patients who underwent mediastinal radiotherapy. Twelve image sets (6 male, 6 female) were used to construct a male and a female population heart model, which was registered to 23 HL "Reference" patients' CT images using a DIR algorithm, MORFEUS. This generated a series of population-to-Reference patient specific 3D deformation maps. The technique was independently tested on 15 additional "Test" patients by reconstructing their 3D heart volumes using 2D digitally reconstructed radiographs (DRR). The technique involved: 1) identifying a matching Reference patient for each Test patient using thorax measurements, 2) placement of six NCs on matching Reference and Test patients' DRRs to capture differences in significant heart curvatures, 3) adapting the population-to-Reference patient-specific deformation maps to generate population-to-Test patient-specific deformation maps using linear and bilinear interpolation methods, 4) applying population-to-Test patient specific deformation to the population model to reconstruct Test-patient specific 3D heart models. The percentage volume overlap between the NC-adapted reconstruction and actual Test patient's true heart volume was calculated using the Dice coefficient. RESULTS: The average Dice coefficient expressed as a percentage between the NC-adapted and actual Test model was 89.4 ± 2.8%. The modified NC adaptation technique made significant improvements to the population deformation heart models (p = 0.01). As standard evaluation, the residual Dice error after adaptation was comparable to the volumetric differences observed in free-breathing heart volumes (p = 0.62). CONCLUSIONS: The reconstruction technique described generates accurate 3D heart models from limited 2D planning data. This development could potentially be used to retrospectively calculate delivered dose to the heart for historically treated patients and thereby provide a better understanding of late radiation-related cardiac effects

    Co-expression of C9orf72 related dipeptide-repeats over 1000 repeat units reveals age-A nd combination-specific phenotypic profiles in Drosophila

    A large intronic hexanucleotide repeat expansion (GGGGCC) within the C9orf72 (C9orf72-SMCR8 Complex Subunit) locus is the most prevalent genetic cause of both Frontotemporal Dementia (FTD) and Motor Neuron Disease (MND). In patients this expansion is typically hundreds to thousands of repeat units in length. Repeat associated non-AUG translation of the expansion leads to the formation of toxic, pathological Dipeptide-Repeat Proteins (DPRs). To date there remains a lack of in vivo models expressing C9orf72 related DPRs with a repeat length of more than a few hundred repeats. As such our understanding of how physiologically relevant repeat length DPRs effect the nervous system in an ageing in vivo system remains limited. In this study we generated Drosophila models expressing DPRs over 1000 repeat units in length, a known pathological length in humans. Using these models, we demonstrate each DPR exhibits a unique, age-dependent, phenotypic and pathological profile. Furthermore, we show co-expression of specific DPR combinations leads to distinct, age-dependent, phenotypes not observed through expression of single DPRs. We propose these models represent a unique, in vivo, tool for dissecting the molecular mechanisms implicated in disease pathology, opening up new avenues in the study of both MND and FTD

All rights reserved. it is reproduced with permissionBackground: Fear of cancer recurrence (FCR) is common amongst cancer survivors. There is rapidly growing research interest in FCR but a need to prioritise research to address the most pressing clinical issues and reduce duplication and fragmentation of effort. This study aimed to establish international consensus among clinical and academic FCR experts regarding priorities for FCR research. Methods: Members of the International Psycho-oncology Society (IPOS) Fear of Cancer Recurrence Special Interest Group (FORwards) were invited to participate in an online Delphi study. Research domains identified in Round 1 were presented and discussed at a focus group (Round 2) to consolidate the domains and items prior to presentation in further survey rounds (Round 3) aimed at gaining consensus on research priorities of international significance. Results: Thirty four research items were identified in Round 1 and 33 of the items were consolidated into 6 overarching themes through a focus group discussion with FCR experts. The 33 research items were presented in subsequent rounds of the delphi technique. Twenty one participants contributed to delphi round 1, 16 in round 2 and 25 and 29 participants for subsequent delphi rounds. Consensus was reached for 27 items in round 3.1. A further 4 research items were identified by panellists and included in round 3.2. After round 3.2, 35 individual research items were ratified by the panellists. Given the high levels of consensus and stability between rounds no further rounds were conducted. Overall intervention research was considered the most important focus for FCR research. Panellists identified models of care that facilitate greater access to FCR treatment and evaluation of the effectiveness of FCR interventions in real world settings as the two research items of highest priority. Defining the mechanisms of action and active components across FCR/P interventions, was the third highest priority identified. Conclusions: The findings of this study outline a research agenda for international FCR research. Intervention research to identify models of care that increase access to treatment, are based on a flexible approach based on symptom severity and can be delivered within routine clinical care, were identified as research areas to prioritise. Greater understanding of the active components and mechanisms of action of existing FCR interventions will facilitate increased tailoring of interventions to meet patient need

    Tropical understory herbaceous community responds more strongly to hurricane disturbance than to experimental warming

    Ecology and Evolution published by John Wiley & Sons Ltd. The effects of climate change on tropical forests may have global consequences due to the forests’ high biodiversity and major role in the global carbon cycle. In this study, we document the effects of experimental warming on the abundance and composition of a tropical forest floor herbaceous plant community in the Luquillo Experimental Forest, Puerto Rico. This study was conducted within Tropical Responses to Altered Climate Experiment (TRACE) plots, which use infrared heaters under free-air, open-field conditions, to warm understory vegetation and soils + 4°C above nearby control plots. Hurricanes Irma and María damaged the heating infrastructure in the second year of warming, therefore, the study included one pretreatment year, one year of warming, and one year of hurricane response with no warming. We measured percent leaf cover of individual herbaceous species, fern population dynamics, and species richness and diversity within three warmed and three control plots. Results showed that one year of experimental warming did not significantly affect the cover of individual herbaceous species, fern population dynamics, species richness, or species diversity. In contrast, herbaceous cover increased from 20% to 70%, bare ground decreased from 70% to 6%, and species composition shifted pre to posthurricane. The negligible effects of warming may have been due to the short duration of the warming treatment or an understory that is somewhat resistant to higher temperatures. Our results suggest that climate extremes that are predicted to increase with climate change, such as hurricanes and droughts, may cause more abrupt changes in tropical forest understories than longer-term sustained warming

    Multinational Experiences in Reducing and Preventing the Use of Restraint and Seclusion

    Restraint and seclusion (R/S) have been used in many countries and across service sectors for centuries. With the recent and increasing recognition of the harm associated with these procedures, efforts have been made to reduce and prevent R/S. Following a scathing media exposé in 1998 and congressional scrutiny, the United States began a national effort to reduce and prevent R/S use. With federal impetus and funding, an evidence-based practice, the Six Core Strategies1 to Prevent Conflict, Violence and the Use of Seclusion and Restraint, was developed. This model was widely and successfully implemented in a number of U.S. states and is being adopted by other countries, including Finland, Australia, and the United Kingdom. Recently, the first cluster randomized controlled study of the Six Core Strategies in Finland provided the first evidence-based data of the safety and effectiveness of a coercion prevention methodology. Preliminary findings of some of the international efforts are discussed. Reduction in R/S use and other positive outcomes are also reported
