The experience of persistent pain and quality of life among women following treatment for breast cancer: An attachment perspective

Objectives: The aims of this study were to investigate associations between attachment and the presence of persistent pain in women following treatment for breast cancer and to investigate the relationship between attachment, pain, and quality of life (QOL) in women with persistent pain. Methods: Women (N = 335) previously diagnosed with primary non-metastatic breast cancer completed an online survey with measures of attachment, pain, QOL, demographics, and medical history. Variables were compared between women with (N = 128) and without (N = 207) persistent pain. For those reporting pain, regression analyses were conducted to investigate relationships between attachment, pain, and QOL. Results: Higher attachment anxiety, but not attachment avoidance, was related to the presence of persistent pain. Among women with persistent pain, associations between attachment anxiety and avoidance and greater pain intensity were lost when pain catastrophizing was considered in analysis. Significant associations between attachment and diminished QOL and perceived effectiveness of pain management were identified in multivariate analysis. Conclusions: These findings extend the available literature regarding associations between pain and attachment insecurity. In women with pain after breast cancer treatment, attachment anxiety and avoidance were associated with negative pain and QOL outcomes. Further attention regarding the use of attachment-informed approaches in supporting women following breast cancer treatment is indicated. © 2018 John Wiley & Sons, Ltd

Protocol for the development of a core domain set for individuals with ankle osteoarthritis

Background: Ankle osteoarthritis (OA) is a debilitating health condition that is increasing in prevalence. Currently, there are no evidence-based guidelines for managing ankle OA. One of the current challenges to establishing guidelines is the lack of a widely agreed-upon set of outcome measures that are consistently used in ankle OA research. Without a set of agreed-upon outcome measures, it is difficult to synthesise clinical trial outcomes through meta-analysis—an essential element of evidence-informed practice. In order to develop an appropriate set of outcome measures for ankle OA, it is important first to develop a core domain set. In this protocol, we describe the methodological approach that we will use to develop such a core domain set for ankle OA. Methods: We established an international steering committee to guide the development of a core domain set for ankle OA. The core domain set development will follow a multi-staged approach consisting of three phases, involving participation by patients and clinicians/healthcare professionals. In phase 1, a list of candidate domains will be gleaned from (a) a scoping review of outcome measures used in ankle OA research, (b) qualitative interviews with individuals with ankle OA, and (c) qualitative interviews with healthcare professionals with expertise in ankle OA. In phase 2, the steering committee will review and generate a list of candidate domains from those gleaned in phase 1. In phase 3, this list of candidate domains will be considered in a Delphi process to reach a consensus on a core domain set. We anticipated this will involve 3 rounds of surveys. Conclusion: This protocol describes the methods that will be used to develop a core domain set of health-related aspects for ankle OA. Importantly, it will include both healthcare professional and patient involvement. This is a prerequisite step to developing a core outcome set for ankle OA that should be reported in all clinical trials for ankle OA. The findings will be widely disseminated across peer-refereed publication(s) and national and international conferences, as well as via relevant professional societies, patient support group organisations, and social media platforms. </p

Gaia Early Data Release 3: Gaia photometric science alerts

Context. Since July 2014, the Gaia mission has been engaged in a high-spatial-resolution, time-resolved, precise, accurate astrometric, and photometric survey of the entire sky. Aims. We present the Gaia Science Alerts project, which has been in operation since 1 June 2016. We describe the system which has been developed to enable the discovery and publication of transient photometric events as seen by Gaia. Methods. We outline the data handling, timings, and performances, and we describe the transient detection algorithms and filtering procedures needed to manage the high false alarm rate. We identify two classes of events: (1) sources which are new to Gaia and (2) Gaia sources which have undergone a significant brightening or fading. Validation of the Gaia transit astrometry and photometry was performed, followed by testing of the source environment to minimise contamination from Solar System objects, bright stars, and fainter near-neighbours. Results. We show that the Gaia Science Alerts project suffers from very low contamination, that is there are very few false-positives. We find that the external completeness for supernovae, CE = 0.46, is dominated by the Gaia scanning law and the requirement of detections from both fields-of-view. Where we have two or more scans the internal completeness is CI = 0.79 at 3 arcsec or larger from the centres of galaxies, but it drops closer in, especially within 1 arcsec. Conclusions. The per-Transit photometry for Gaia transients is precise to 1% at G = 13, and 3% at G = 19. The per-Transit astrometry is accurate to 55 mas when compared to Gaia DR2. The Gaia Science Alerts project is one of the most homogeneous and productive transient surveys in operation, and it is the only survey which covers the whole sky at high spatial resolution (subarcsecond), including the Galactic plane and bulge
