Dementia-friendly Design of Television News Broadcasts

Purpose - To understand factors that affect viewing of television news programmes by people living with dementia; to identify dementia-friendly design principles for television news programmes and factors for personalising object-based media broadcast. Design - Public involvement comprising two discussion groups with people with dementia and family carers informed the study design and provided supplementary secondary data. Primary data collection comprised a focus group interview with people with dementia (n=4) and family carers (n=4). Past viewing experiences and perceived barriers and facilitators to viewing television were explored. Participants commented on an array of video clips comprising varying segments of fictional news programmes, plus control versions of each segment. Findings - Four themes were identified: Content (general comments, context, type of media and pace); Presenter (body language, clothing and accent); Background (location and studio appearance); Technical aspects (graphics, sound, colours, camera, transitions, general issues). Research limitations - Limitations included modest sample size Practical implications - Measures ensured research involvement and participation was made accessible to people living with dementia. Social implications - Participants benefited from sharing views with peers and expressed enhanced wellbeing from knowing their participation could lead to improved television viewing, an important social occupation, for people with dementia in the future. Originality/value - This study is the first to be published which focuses on dementia-friendly television news programmes. Paper type - Research stud

Fast and Uniform Optically-Switched Data Centre Networks Enabled by Amplitude Caching

We propose amplitude caching to optically equalise burst mode traffic without delay stages. Through a fast, optically-switched system prototype, we demonstrate burst-mode penalties can be mitigated to within 0.4 dB at the KR4 HD-FEC level

Healthcare Game Design: Behavioral Modeling of Serious Gaming Design for Children with Chronic Diseases

This article introduces the design principles of serious games for chronic patients based on behavioral models. First, key features of the targeted chronic condition (Diabetes) are explained. Then, the role of psychological behavioral models in the management of chronic conditions is covered. After a short review of the existing health focused games, two recent health games that are developed based on behavioral models are overviewed in more detail. Furthermore, design principles and usability issues regarding the creation of these health games are discussed. Finally, the authors conclude that designing healthcare games based on behavioral models can increase the usability of the game in order to improve the effectiveness of the game’s desired healthcare outcomes

A HER2 selective theranostic agent for surgical resection guidance and photodynamic therapy

In many cancers early intervention involves surgical resection of small localised tumour masses. Inadequate resection leads to recurrence whereas overzealous treatment can lead to organ damage. This work describes production of a HER2 targeting antibody Fab fragment dual conjugated to achieve both real time near-infrared fluorescent imaging and photodynamic therapy. The use of fluorescence emission from a NIR-dye could be used to guide resection of tumour bulk, for example during endoscopic diagnosis for oesophago-gastric adenocarcinoma, this would then be followed by activation of the photodynamic therapeutic agent to destroy untreated localised areas of cancer infiltration and tumour infiltrated lymph nodes. This theranostic agent was prepared from the Fab fragment of trastuzumab initially by functional disulfide re-bridging and site-specific click reaction of a NIR-dye. This was followed by further reaction with a novel pre-activated form of the photosensitiser chlorin e6 with the exposed fragments' lysine residues. Specific binding of the theranostic agent was observed in vitro with a HER2 positive cell line and cellular near-infrared fluorescence was observed with flow cytometry. Specific photo-activity of the conjugates when exposed to laser light was observed with HER2 positive but not HER2 negative cell lines in vitro, this selectivity was not seen with the unconjugated drug. This theranostic agent demonstrates that two different photo-active functions can be coupled to the same antibody fragment with little interference to their independent activities

The effectiveness of peer health coaching in improving glycemic control among low-income patients with diabetes: protocol for a randomized controlled trial

<p>Abstract</p> <p>Background</p> <p>Although self-management support improves diabetes outcomes, it is not consistently provided in health care settings strained for time and resources. One proposed solution to personnel and funding shortages is to utilize peer coaches, patients trained to provide diabetes education and support to other patients. Coaches share similar experiences about living with diabetes and are able to reach patients within and beyond the health care setting. Given the limited body of evidence that demonstrates peer coaching significantly improves chronic disease care, this present study examines the impact of peer coaching delivered in a primary care setting on diabetes outcomes.</p> <p>Methods/Design</p> <p>The aim of this multicenter, randomized control trial is to evaluate the effectiveness of utilizing peer coaches to improve clinical outcomes and self-management skills in low-income patients with poorly controlled diabetes. A total of 400 patients from six primary health centers based in San Francisco that serve primarily low-income populations will be randomized to receive peer coaching (n = 200) or usual care (n = 200) over 6 months. Patients in the peer coach group receive coaching from patients with diabetes who are trained and mentored as peer coaches. The primary outcome is change in HbA1c. Secondary outcomes include change in: systolic blood pressure, body mass index (BMI), LDL cholesterol, diabetes self-care activities, medication adherence, diabetes-related quality of life, diabetes self-efficacy, and depression. Clinical values (HbA1c, LDL cholesterol and blood pressure) and self-reported diabetes self-efficacy and self-care activities are measured at baseline and after 6 months for patients and coaches. Peer coaches are also assessed at 12 months.</p> <p>Discussion</p> <p>Patients with diabetes, who are trained as peer health coaches, are uniquely poised to provide diabetes self management support and education to patients. This study is designed to investigate the impact of peer health coaching in patients with poorly controlled diabetes. Additionally, we will assess disease outcomes in patients with well controlled diabetes who are trained and work as peer health coaches.</p> <p>Trial Registration</p> <p>ClinicalTrials.gov identifier: <a href="http://www.clinicaltrials.gov/ct2/show/NCT01040806">NCT01040806</a></p

Health care professionals meeting with individuals with Type 2 diabetes and obesity: Balancing coaching and caution

The burden of diabetes and obesity is increasing worldwide, indicating a need to find the best standard for diabetes care. The aim of this study was to generate a theory grounded in empirical data derived from a deeper understanding of health care professionals’ main concerns when they consult with individuals with diabetes and obesity and how they handle these concerns. Tape-recorded interviews were conducted with seven groups and three individual members of a diabetes team in an area of western Sweden. The grounded theory (GT) method was used to analyse the transcribed interviews. A core category, labelled Balancing coaching and caution and three categories (Coaching and supporting, Ambivalence and uncertainty, and Adjusting intentions) emerged. The core category and the three categories formed a substantive theory that explained and illuminated how health care professionals manage their main concern; their ambition to give professional individualised care; and find the right strategy for each individual with diabetes and obesity. The theory generated by this study can improve our understanding of how a lack of workable strategies limits caregivers’ abilities to reach their goals. It also helps identify the factors that contribute to the complexity of meetings between caregivers and individuals with diabetes

Complex, but not quite complex enough : The turn to the complexity sciences in evaluation scholarship

This document is the Accepted Manuscript version of the following article: Chris Mowles, ‘Complex, but not quite complex enough: The turn to the complexity sciences in evaluation scholarship’. The final, definitive version of this paper has been published in Evaluation, Vol. 20 (2): 160-175, April 2014, doi: https://doi.org/10.1177/1356389014527885 , published by SAGE Publishing. All rights reserved.This article offers a critical review of the way in which some scholars have taken up the complexity sciences in evaluation scholarship. I argue that there is a tendency either to over-claim or under-claim their importance because scholars are not always careful about which of the manifestations of the complexity sciences they are appealing to, nor do they demonstrate how they understand them in social terms. The effect is to render ‘complexity’ just another volitional tool in the evaluator’s toolbox subsumed under the dominant understanding of evaluation, as a logical, rational activity based on systems thinking and design. As an alternative I argue for a radical interpretation of the complexity sciences, which understands human interaction as always complex and emergent. The interweaving of intentions in human activity will always bring about outcomes that no one has intended including in the activity of evaluation itself.Peer reviewe
