Cold dialysis and its impact on renal patients’ health: An evidence-based mini review
Get PDFChronic renal disease is associated with advanced age, diabetes, hypertension, obesity, musculoskeletal problems and cardiovascular disease, the latter being the main cause of mortality in patients receiving haemodialysis (HD). Cooled dialysate (35 °C-36 °C) is recently employed to reduce the incidence of intradialytic hypotension in patients on chronic HD. The studies to date that have evaluated cooled dialysate are limited, however, data suggest that cooled dialysate improves hemodynamic tolerability of dialysis, minimizes hypotension and exerts a protective effect over major organs including the heart and brain. The current evidence-based review is dealing with the protective effect of cold dialysis and the benefits of it in aspects affecting patients’ quality of care and life. There is evidence to suggest that cold dialysis can reduce cardiovascular mortality. However, large multicentre randomized clinical trials are urgently needed to provide further supporting evidence in order to incorporate cold dialysis in routine clinical practice
Conceptualising on-screen Tourism Destination Development
Get PDFThis article integrates cultural theory and marketing strategy to examine the complex relationship between on-screen popular culture and tourism destination place-making. Its review of the literature results in the development of an interdisciplinary conceptual framework (termed ‘on-screen dollying’) that provides a culturally grounded and contextually driven theorisation of the means by which on-screen popular culture place-making can foster destination development. In developing the conceptual framework, the article classifies the characteristics of on-screen tourism affecting destination development and identifies six strategies for leveraging on-screen tourism. Based on our interdisciplinary analysis, we propose a research agenda that integrates on-screen tourism and destination place-making and which has implications for policy and theory
Corporate sponsorship of physical activity promotion programmes: part of the solution or part of the problem?
Get PDFBackground
Parklives is a programme intended to raise levels of physical activity across the UK, funded by Coca-Cola GB and delivered in association with Local Authorities and other organizations. Such public-private partnerships have been advocated by many however critics suggest that the conflict between stakeholder motives is too great.
Methods
This study conducted a content analysis of twitter content related to the ParkLives physical activity programme. Images and text were analysed from two separate weeks, one from the school vacation period and one during school term time.
Results
Three hundred and eighteen tweets were analysed. Content analysis revealed 79% of images contained children and 45% of these images contained prominent Coca-Cola branding, a level of exposure that suggests ParkLives simultaneously provides opportunities for children's physical activity and for targeted marketing. Content analysis also demonstrated that the programme allowed increased access to policy-makers.
Conclusions
The sponsorship of a physical activity promotion campaign can allow a corporation to target its marketing at children and gain access to health-related policy development networks. This study reinforces the need for independent evaluation of all potential impacts of such a partnership and calls on those responsible for community health to fully consider the ethical implications of such relationships
Resonance Tube Phonation in Water—the Effect of Tube Diameter and Water Depth on Back Pressure and Bubble Characteristics at Different Airflows
No full textObjectives:
Resonance tube phonation with tube end in water is a voice therapy method in which the patient phonates through a glass tube, keeping the free end of the tube submerged in water, creating bubbles. The purpose of this experimental study was to determine flow-pressure relationship, flow thresholds between bubble types, and bubble frequency as a function of flow and back volume.
Methods
A flow-driven vocal tract simulator was used for recording the back pressure produced by resonance tubes with inner diameters of 8 and 9 mm submerged at water depths of 0–7 cm. Visual inspection of bubble types through video recording was also performed.
Results
The static back pressure was largely determined by the water depth. The narrower tube provided a slightly higher back pressure for a given flow and depth. The amplitude of the pressure oscillations increased with flow and depth. Depending on flow, the bubbles were emitted from the tube in three distinct types with increasing flow: one by one, pairwise, and in a chaotic manner. The bubble frequency was slightly higher for the narrower tube. An increase in back volume led to a decrease in bubble frequency.
Conclusions
This study provides data on the physical properties of resonance tube phonation with the tube end in water. This information will be useful in future research when looking into the possible effects of this type of voice training
Sedentary Behavior Research Network (SBRN) – Terminology Consensus Project process and outcome
No full textBackground:
The prominence of sedentary behavior research in health science has grown rapidly. With this growth there is increasing urgency for clear, common and accepted terminology and definitions. Such standardization is difficult to achieve, especially across multi- disciplinary researchers, practitioners, and industries. The Sedentary Behavior Research Network (SBRN) undertook a Terminology Consensus Project to address this need.
Method:
First, a literature review was completed to identify key terms in sedentary behavior research. These key terms were then reviewed and modified by a Steering Committee formed by SBRN. Next, SBRN members were invited to contribute to this project and interested participants reviewed and provided feedback on the proposed list of terms and draft definitions through an online survey. Finally, a conceptual model and consensus definitions (including caveats and examples for all age groups and functional abilities) were finalized based on the feedback received from the 87 SBRN member participants who responded to the original invitation and survey.
Results:
Consensus definitions for the terms physical inactivity, stationary behavior, sedentary behavior, standing, screen time, non-screen-based sedentary time, sitting, reclining, lying, sedentary behavior pattern, as well as how the terms bouts, breaks, and interruptions should be used in this context are provided.
Conclusion:
It is hoped that the definitions resulting from this comprehensive, transparent, and broad-based participatory process will result in standardized terminology that is widely supported and adopted, thereby advancing future research, interventions, policies, and practices related to sedentary behaviors
Telling stories in Organisations: Reflective Practice/Curated Practice
No full textStories are important to and within organisations. Those told through reflective practice focus on the experience of practice in relation to the teller with an aim of developing service to others. However, issues at the heart of the way this is typically approached result in the telling of familiar and fixed stories, eradicating creativity. The production of fixed, familiar stories compromises any positive potential that engagement may have offered. In this paper I propose that reflection-in-action offers a way forward. In particular I focus on the 'threshold concepts' (Meyer & Land, 2006) of Gaze, Glance and Letting Go that emerged during four years of doctoral research. The paper describes the first two of these, Gaze and Glance, and their contribution to 'mittere', an alternative reflective practice methodology for organisations. Mittere centres on telling stories through a process that is fresh, playful and creative
What it takes to be an athlete.
Get PDFIn 2012, The Psychologist ran an article entitled 'What does the Olympics mean to you?' Themes of inclusion, (dis)ability, learning, diversity, development, role modelling, legacy, and many more came up. Suffice it to say, the Olympics make us think. A lot. And in very diverse ways. It’s incredible what a sporting event can do to make us reflect on broader society. Given the 2018 Winter Olympics are around the corner, undoubtedly some of us will engage in some form of refection. To jump start the process, I asked myself and a few colleagues, what the Winter Olympics mean to us.
