Does image congruence impact the effectiveness of a gain-framed physical activity message?

This is a pre-publication version of the following article: Neil Howlett, Joanne Gardiner & Abbie Foster, 'Does image congruence impact the effectiveness of gain-framed physical activity message? ', Health Psychology Update, Vol. 26 (1): Spring 2017. The version of record is available online at https://shop.bps.org.uk/publications/publication-by-series/health-psychology-update/health-psychology-update-vol-26-no-1-spring-2017.html. Published by the British Psychological Society.Background: Gain-framed messages can improve processing and physical activity, however inconsistency remains about the merits of using different accompanying images. This study explored whether gain-framed messages alongside positive images (congruent) were more effective than negative (incongruent) images at increasing Social Cognitive Theory (SCT) constructs and moderate-to-vigorous physical activity (MVPA). Method: Using a mixed design participants (N=110) were randomly assigned to read a gain-framed physical activity booklet containing either congruent or incongruent images. Data were collected at two time points (baseline and one week later) using online questionnaires assessing SCT constructs and interviews about MVPA over the previous seven days. Results: A time by condition interaction showed that intentions (p=.039, η2=.04) and self-efficacy (p=.005, η2=.07) increased in the congruent condition only. There was a time main effect for self-regulation (p=.001, η2=.09) and MVPA (p=.011, η2=.06), but no difference between conditions. Changes in self-regulation predicted changes in MVPA in both conditions (congruent, p=.003; incongruent, p=.030). Conclusions: Congruence between message content and images increased intentions and self-efficacy, but not MVPA. Improving self-regulation may increase physical activity levels regardless of message congruence.Peer reviewedFinal Accepted Versio

Ensuring that the outcome domains proposed for use in burns research are relevant to adult burn patients:a systematic review of qualitative research evidence

Background There have been several attempts to define core outcome domains for use in research focused on adult burns. Some have been based in expert opinion, whilst others have used primary qualitative research to understand patients’ perspectives on outcomes. To date there has not been a systematic review of qualitative research in burns to identify a comprehensive list of patient-centred outcome domains. We therefore conducted a systematic review of qualitative research studies in adult burns. Methods We searched multiple databases for English-language, peer-reviewed, qualitative research papers. We used search strategies devised using the SPIDER tool for qualitative synthesis. Our review utilized an iterative three-step approach: (1) outcome-focused coding; (2) development of descriptive accounts of outcome-relevant issues; and (3) revisiting studies and the broader theoretical literature in order to frame the review findings. Results Forty-one articles were included. We categorized papers according to their primary focus. The category with the most papers was adaptation to life following burn injury (n = 13). We defined 19 outcome domains across the 41 articles: (1) sense of self; (2) emotional and psychological morbidity; (3) sensory; (4) scarring and scar characteristics; (5) impact on relationships; (6) mobility and range of joint motion; (7) work; (8) activities of daily living and self-care; (9) treatment burden; (10) engagement in activities; (11) wound healing and infection; (12) other physical manifestations; (13) financial impact; (14) impact on spouses and family members; (15) analgesia and side effects; (16) cognitive skills; (17) length of hospital stay; (18) access to healthcare; and (19) speech and communication. We suggest that sense of self is a core concern for patients that, to date, has not been clearly conceptualized in the burns outcome domain literature. Conclusions This outcome domain framework identifies domains that are not covered in previous attempts to outline core outcome domains for adult burn research. It does so with reference to existing theoretical perspectives from the sociology and psychology of medicine. We propose that this framework can be used as a basis to ensure that outcome assessment is patient-centred. Sense of self requires further consideration as a core outcome domain

Co-targeting RNA Polymerases IV and V Promotes Efficient De Novo DNA Methylation in Arabidopsis.

The RNA-directed DNA methylation (RdDM) pathway in plants controls gene expression via cytosine DNA methylation. The ability to manipulate RdDM would shed light on the mechanisms and applications of DNA methylation to control gene expression. Here, we identified diverse RdDM proteins that are capable of targeting methylation and silencing in Arabidopsis when tethered to an artificial zinc finger (ZF-RdDM). We studied their order of action within the RdDM pathway by testing their ability to target methylation in different mutants. We also evaluated ectopic siRNA biogenesis, RNA polymerase V (Pol V) recruitment, targeted DNA methylation, and gene-expression changes at thousands of ZF-RdDM targets. We found that co-targeting both arms of the RdDM pathway, siRNA biogenesis and Pol V recruitment, dramatically enhanced targeted methylation. This work defines how RdDM components establish DNA methylation and enables new strategies for epigenetic gene regulation via targeted DNA methylation

Site investigation for the effects of vegetation on ground stability

The procedure for geotechnical site investigation is well established but little attention is currently given to investigating the potential of vegetation to assist with ground stability. This paper describes how routine investigation procedures may be adapted to consider the effects of the vegetation. It is recommended that the major part of the vegetation investigation is carried out, at relatively low cost, during the preliminary (desk) study phase of the investigation when there is maximum flexibility to take account of findings in the proposed design and construction. The techniques available for investigation of the effects of vegetation are reviewed and references provided for further consideration. As for general geotechnical investigation work, it is important that a balance of effort is maintained in the vegetation investigation between (a) site characterisation (defining and identifying the existing and proposed vegetation to suit the site and ground conditions), (b) testing (in-situ and laboratory testing of the vegetation and root systems to provide design parameters) and (c) modelling (to analyse the vegetation effects)

Recon 2.2: from reconstruction to model of human metabolism.

IntroductionThe human genome-scale metabolic reconstruction details all known metabolic reactions occurring in humans, and thereby holds substantial promise for studying complex diseases and phenotypes. Capturing the whole human metabolic reconstruction is an on-going task and since the last community effort generated a consensus reconstruction, several updates have been developed.ObjectivesWe report a new consensus version, Recon 2.2, which integrates various alternative versions with significant additional updates. In addition to re-establishing a consensus reconstruction, further key objectives included providing more comprehensive annotation of metabolites and genes, ensuring full mass and charge balance in all reactions, and developing a model that correctly predicts ATP production on a range of carbon sources.MethodsRecon 2.2 has been developed through a combination of manual curation and automated error checking. Specific and significant manual updates include a respecification of fatty acid metabolism, oxidative phosphorylation and a coupling of the electron transport chain to ATP synthase activity. All metabolites have definitive chemical formulae and charges specified, and these are used to ensure full mass and charge reaction balancing through an automated linear programming approach. Additionally, improved integration with transcriptomics and proteomics data has been facilitated with the updated curation of relationships between genes, proteins and reactions.ResultsRecon 2.2 now represents the most predictive model of human metabolism to date as demonstrated here. Extensive manual curation has increased the reconstruction size to 5324 metabolites, 7785 reactions and 1675 associated genes, which now are mapped to a single standard. The focus upon mass and charge balancing of all reactions, along with better representation of energy generation, has produced a flux model that correctly predicts ATP yield on different carbon sources.ConclusionThrough these updates we have achieved the most complete and best annotated consensus human metabolic reconstruction available, thereby increasing the ability of this resource to provide novel insights into normal and disease states in human.

Feminist Reflections on the Scope of Labour Law: Domestic Work, Social Reproduction and Jurisdiction

Drawing on feminist labour law and political economy literature, I argue that it is crucial to interrogate the personal and territorial scope of labour. After discussing the “commodification” of care, global care chains, and body work, I claim that the territorial scope of labour law must be expanded beyond that nation state to include transnational processes. I use the idea of social reproduction both to illustrate and to examine some of the recurring regulatory dilemmas that plague labour markets. I argue that unpaid care and domestic work performed in the household, typically by women, troubles the personal scope of labour law. I use the example of this specific type of personal service relation to illustrate my claim that the jurisdiction of labour law is historical and contingent, rather than conceptual and universal. I conclude by identifying some of the implications of redrawing the territorial and personal scope of labour law in light of feminist understandings of social reproduction

Synthetic spatially graded Rac activation drives directed cell polarization and locomotion

Migrating cells possess intracellular gradients of Rho GTPases, but it is unknown whether these shallow gradients themselves can induce motility. Here we describe a new method to present cells with induced linear gradients of active, endogenous Rac without receptor activation. Gradients as low as 15% were sufficient to not only trigger cell migration up the synthetic gradient, but also to induce both cell polarization and repolarization. Response kinetics were inversely proportional to Rac gradient values, in agreement with a new mathematical model, suggesting a role for natural input gradient amplification upstream of Rac. Increases in Rac levels beyond a well-defined threshold dramatically augmented polarization and decreased sensitivity to the gradient value. The threshold was governed by initial cell polarity and PI3K activity, supporting a role for both in defining responsiveness to natural or synthetic Rac activation. Our methodology suggests a general way to investigate processes regulated by intracellular signaling gradients

Supportive care for older people with frailty in hospital: An integrative review

BACKGROUND: Growing numbers of older people living with frailty and chronic health conditions are being referred to hospitals with acute care needs. Supportive care is a potentially highly relevant and clinically important approach which could bridge the practice gap between curative models of care and palliative care. However, future interventions need to be informed and underpinned by existing knowledge of supportive care. AIM: To identify and build upon existing theories and evidence about supportive care, specifically in relation to the hospital care of older people with frailty, to inform future interventions and their evaluation. DESIGN: An integrative review was used to identify and integrate theory and evidence. Electronic databases (Cochrane Medline, EMBASE and CIHAHL) were searched using the key term 'supportive care'. Screening identified studies employing qualitative and/or quantitative methods published between January 1990 and December 2015. Citation searches, reference checking and searches of the grey literature were also undertaken. DATA SOURCES: Literature searches identified 2733 articles. After screening, and applying eligibility criteria based on relevance to the research question, studies were subject to methodological quality appraisal. Findings from included articles (n=52) were integrated using synthesis of themes. RESULTS: Relevant evidence was identified across different research literatures, on clinical conditions and contexts. Seven distinct themes of the synthesis were identified, these were: Ensuring fundamental aspects of care are met, Communicating and connecting with the patient, Carer and family engagement, Building up a picture of the person and their circumstances, Decisions and advice about best care for the person, Enabling self-help and connection to wider support, and Supporting patients through transitions in care. A tentative integrative model of supportive care for frail older people is developed from the findings. CONCLUSION: The findings and model developed here will inform future interventions and can help staff and hospital managers to develop appropriate strategies, staff training and resource allocation models to improve the quality of health care for older people

Diagnostic and treatment pathways for men with prostate cancer in Queensland: investigating spatial and demographic inequalities

Background: Patterns of diagnosis and management for men diagnosed with prostate cancer in Queensland, Australia, have not yet been systematically documented and so assumptions of equity are untested. This longitudinal study investigates the association between prostate cancer diagnostic and treatment outcomes and key area-level characteristics and individual-level demographic, clinical and psychosocial factors.---------- Methods/Design: A total of 1064 men diagnosed with prostate cancer between February 2005 and July 2007 were recruited through hospital-based urology outpatient clinics and private practices in the centres of Brisbane, Townsville and Mackay (82% of those referred). Additional clinical and diagnostic information for all 6609 men diagnosed with prostate cancer in Queensland during the study period was obtained via the population-based Queensland Cancer Registry. Respondent data are collected using telephone and self-administered questionnaires at pre-treatment and at 2 months, 6 months, 12 months, 24 months, 36 months, 48 months and 60 months post-treatment. Assessments include demographics, medical history, patterns of care, disease and treatment characteristics together with outcomes associated with prostate cancer, as well as information about quality of life and psychological adjustment. Complementary detailed treatment information is abstracted from participants’ medical records held in hospitals and private treatment facilities and collated with health service utilisation data obtained from Medicare Australia. Information about the characteristics of geographical areas is being obtained from data custodians such as the Australian Bureau of Statistics. Geo-coding and spatial technology will be used to calculate road travel distances from patients’ residences to treatment centres. Analyses will be conducted using standard statistical methods along with multilevel regression models including individual and area-level components.---------- Conclusions: Information about the diagnostic and treatment patterns of men diagnosed with prostate cancer is crucial for rational planning and development of health delivery and supportive care services to ensure equitable access to health services, regardless of geographical location and individual characteristics. This study is a secondary outcome of the randomised controlled trial registered with the Australian New Zealand Clinical Trials Registry (ACTRN12607000233426
