Psychosocial predictors of hope two years after diagnosis of colorectal cancer: Implications for nurse-led hope programmes
© 2019 John Wiley & Sons Ltd Objective: To prospectively explore predictors of hope in people with colorectal cancer at 24 months post-diagnosis. Methods: The present study is a secondary analysis of two waves within a longitudinal survey of patients newly diagnosed with colorectal cancer in Queensland, Australia. Baseline predictors (sociodemographic, disease, lifestyle characteristics, cancer threat appraisal and quality of life domains) were measured via mailed surveys and telephone interviews at 6 months post-diagnosis. Hope was measured via mailed surveys at 24 months post-diagnosis. Results: At 24 months post-diagnosis, 1,265 participants completed the hope measure. Hope was predicted by higher education, physical activity, cancer threat appraisal and each quality of life domain (i.e., physical, social, emotional and functional well-being; and colorectal cancer-specific concerns), which explained 23.63% of the total variance in hope, F(14, 1,081) = 23.89, p < 0.001. Conclusion: At 24 months post-diagnosis, hope was associated with greater functional, social and emotional well-being, and less threatened cancer appraisals. As hope programmes continue to be developed, designers should include activities that increase well-being and reduce cancer threat appraisal for people with colorectal cancer

Effectiveness of nursing rounds in the Intensive Care Unit on workplace learning
Objectives: To evaluate the implementation of a regular Nursing Round as an educational strategy for workplace learning in an intensive care unit with a single room environment.
Research design: A multiple methods design was used. Fifty-four Nursing Rounds were observed and nurses (nâŻ=âŻ40) completed bespoke evaluative surveys. Structured observational data and open-ended survey responses were submitted to content analysis and descriptive statistics were used to analyse survey findings.
Results: Nursing Rounds involved a diverse range of participants, most frequently nurses. The content most frequently discussed included empirical clinical issues where nurses decided on nursing care actions to address these issues. The most frequently observed outcome of Nursing Rounds was knowledge translation. Nursing Rounds were perceived to positively influence application of evidence in practise, identification of areas for practise improvement and ability to communicate clinical information. Two categories emerged from analysis of open-ended survey questions; (1) âPositive learning environmentâ, where nurses described Nursing Rounds as a social learning experience; and (2) âImpediments to Nursing Roundsâ, including difficulty attending Nursing Rounds due to competing priorities.
Conclusion: Nursing Rounds enabled evidence-based learning that enhanced inter-disciplinary collaboration. Further investigation may be required to understand how to enable nurses to attend more frequently, and generate a more holistic, evidence-based discussion

Investigating the Potential and Pitfalls of EV-Encapsulated MicroRNAs as Circulating Biomarkers of Breast Cancer
Extracellular vesicles (EVs) shuttle microRNA (miRNA) throughout the circulation and are believed to represent a fingerprint of the releasing cell. We isolated and characterized serum EVs of breast tumour-bearing animals, breast cancer (BC) patients, and healthy controls. EVs were characterized using transmission electron microscopy (TEM), protein quantification, western blotting, and nanoparticle tracking analysis (NTA). Absolute quantitative (AQ)-PCR was employed to analyse EV-miR-451a expression. Isolated EVs had the appropriate morphology and size. Patient sera contained significantly more EVs than did healthy controls. In tumour-bearing animals, a correlation between serum EV number and tumour burden was observed. There was no significant relationship between EV protein yield and EV quantity determined by NTA, highlighting the requirement for direct quantification. Using AQ-PCR to relate miRNA copy number to EV yield, a significant increase in miRNA-451a copies/EV was detected in BC patient sera, suggesting potential as a novel biomarker of breast cancer
The âebb and flowâ of student learning on placement
There is a rise in interest in work based learning as part of student choice at subject level in the UK (DOE 2017) but there remains an absence of specific guidance on how to best support higher education students learning on placement. An alternative HE experience in England, the degree apprenticeship, underlies the continued focus by policy in securing placement experiences for students without stipulating the type of support that is required at the âcoal faceâ of work based learning. Policy documents (UUK 2016), that urge universities to enter into partnership agreements with both employers and FE colleges to plug skills shortages, are noticeably lacking in their appreciation of the unique qualities of work based learning and how best to support students in this setting (Morley 2017a). Unfortunately, this is not unusual as placements have predominantly been an enriching âadd onâ to the real business of academic learning in more traditional university programmes. Support initiatives, such as that described in chapter 9, are a rare appreciation of the importance of this role. Undergraduate nursing programmes currently support a 50:50 split between practice learning in clinical placements and the theory delivered at universities. Vocational degrees, such as this, provide an interesting case study as to how students can be supported in the practice environment by an appreciation of how students really learn on placement and how hidden resources can be utilised more explicitly for practice learning. During 2013 â 2015 a professional doctorate research study (Morley 2015) conducted a grounded theory study of 21 first year student nurses on their first placement to discover how they learnt âat workâ and the strategies they enlisted to be successful work based learners
Oct4-Induced Reprogramming Is Required for Adult Brain Neural Stem Cell Differentiation into Midbrain Dopaminergic Neurons
Neural stem cells (NSCs) lose their competency to generate region-specific neuronal populations at an early stage during embryonic brain development. Here we investigated whether epigenetic modifications can reverse the regional restriction of mouse adult brain subventricular zone (SVZ) NSCs. Using a variety of chemicals that interfere with DNA methylation and histone acetylation, we showed that such epigenetic modifications increased neuronal differentiation but did not enable specific regional patterning, such as midbrain dopaminergic (DA) neuron generation. Only after Oct-4 overexpression did adult NSCs acquire a pluripotent state that allowed differentiation into midbrain DA neurons. DA neurons derived from Oct4-reprogrammed NSCs improved behavioural motor deficits in a rat model of Parkinson's disease (PD) upon intrastriatal transplantation. Here we report for the first time the successful differentiation of SVZ adult NSCs into functional region-specific midbrain DA neurons, by means of Oct-4 induced pluripotency
