BackgroundThe prevalence of physical chronic or long-term conditions in adolescents aged 10-24 years is rising. Mobile phone and tablet mobile technologies featuring software program apps are widely used by these adolescents and their healthy peers for social networking or gaming. Apps are also used in health care to support personal condition management and they have considerable potential in this context. There is a growing body of literature on app use in health contexts, thereby making a systematic review of their effectiveness very timely.ObjectiveTo systematically review the literature on the effectiveness of mobile apps designed to support adolescents’ management of their physical chronic or long-term conditions.MethodsWe conducted a review of the English-language literature published since 2003 in five relevant bibliographical databases using key search terms. Two independent reviewers screened titles and abstracts using data extraction and quality assessment tools.ResultsThe search returned 1120 hits. Of the 19 eligible full-text papers, four met our review criteria, reporting one pilot randomized controlled trial and three pretest/post-test studies. Samples ranged from 4 to 18 participants, with a combined sample of 46 participants. The apps reported were targeted at type 1 diabetes, asthma, and cancer. Two papers provided data for calculating effect size. Heterogeneity in terms of study design, reported outcomes, follow-up times, participants’ ages, and health conditions prevented meta-analyses. There was variation in whether adolescents received guidance in using the app or were solely responsible for navigating the app. Three studies reported some level of patient involvement in app design, development, and/or evaluation. Health professional involvement in the modelling stages of apps was reported in all studies, although it was not always clear whether specific clinical (as opposed to academic) expertise in working with adolescents was represented. The dearth of studies and the small overall sample size emphasizes the need for future studies of the development, evaluation, use, and effectiveness of mobile apps to support adolescents’ personal management of their conditions.ConclusionsA key finding of the review is the paucity of evidence-based apps that exist, in contrast to the thousands of apps available on the app market that are not evidence-based or user or professional informed. Although we aimed to assess the effectiveness of apps, the dearth of studies meeting our criteria meant that we were unable to be conclusive in this regard. Based on the available evidence, apps may be considered feasible health interventions, but more studies involving larger sample sizes, and with patient and health professional input at all stages, are needed to determine apps’ acceptability and effectiveness. This review provides valuable findings and paves the way for future rigorous development and evaluation of health apps for adolescents with chronic or long-term conditions.

Background Qualitative olfactory (smell) dysfunctions are a common side effect of post-viral illness and known to impact quality of life and health status. Evidence is emerging that taste and smell loss are common symptoms of Covid-19 that may emerge and persist long after initial infection. The aim of the present study was to document the impact of post Covid-19 alterations to taste and smell. Methods We conducted exploratory thematic analysis of user-generated text from 9000 users of the AbScent Covid-19 Smell and Taste Loss moderated Facebook support group from March 24 to 30th September 2020. Results Participants reported difficulty explaining and managing an altered sense of taste and smell; a lack of interpersonal and professional explanation or support; altered eating; appetite loss, weight change; loss of pleasure in food, eating and social engagement; altered intimacy and an altered relationship to self and others. Conclusions Our findings suggest altered taste and smell with Covid-19 may lead to severe disruption to daily living that impacts on psychological well-being, physical health, relationships and sense of self. More specifically, participants reported impacts that related to reduced desire and ability to eat and prepare food; weight gain, weight loss and nutritional insufficiency; emotional wellbeing; professional practice; intimacy and social bonding; and the disruption of people’s sense of reality and themselves. Our findings should inform further research and suggest areas for the training, assessment and treatment practices of health care professionals working with long Covid.

BackgroundEffective weight loss interventions are widely available but, after weight loss, most individuals regain weight. This article describes the protocol for the NULevel trial evaluating the effectiveness and cost-effectiveness of a systematically developed, inexpensive, scalable, technology-assisted, behavioural intervention for weight loss maintenance (WLM) in obese adults after initial weight loss.Methods/DesignA 12-month single-centre, two-armed parallel group, participant randomised controlled superiority trial is underway, recruiting a total of 288 previously obese adults after weight loss of ≥5 % within the previous 12 months. Participants are randomly assigned to intervention or control arms, with a 1:1 allocation, stratified by sex and percentage of body weight lost (<10 % vs ≥10 %). Change in weight (kg) from baseline to 12 months is the primary outcome. Weight, other anthropometric variables and 7-day physical activity (assessed via accelerometer) measures are taken at 0 and 12 months. Questionnaires at 0, 6 and 12 months assess psychological process variables, health service use and participant costs. Participants in the intervention arm initially attend an individual face-to-face WLM consultation with an intervention facilitator and then use a mobile internet platform to self-monitor and report their diet, daily activity (via pedometer) and weight through daily weighing on wirelessly connected scales. Automated feedback via mobile phone, tailored to participants’ weight regain and goal progress is provided. Participants in the control arm receive quarterly newsletters (via links embedded in text messages) and wirelessly connected scales. Qualitative process evaluation interviews are conducted with a subsample of up to 40 randomly chosen participants. Acceptability and feasibility of procedures, cost-effectiveness, and relationships among socioeconomic variables and WLM will also be assessed.DiscussionIt is hypothesised that participants allocated to the intervention arm will show significantly lower levels of weight regain from baseline than those in the control arm. To date, this is the first WLM trial using remote real-time weight monitoring and mobile internet platforms to deliver a flexible, efficient and scalable intervention, tailored to the individual. This trial addresses a key research need and has the potential to make a vital contribution to the evidence base to inform future WLM policy and provision.Trial registrationhttp://www.isrctn.com/ISRCTN14657176 (registration date 20 March 2014).

BACKGROUNDDigital contact tracing apps have been proposed as a method of controlling the spread of Covid-19. The effectiveness of this tool depends largely on adequate levels of uptake (e.g. whether the user downloads and registers on the application) and engagement (e.g. the extent of usage of the application or its components over time). It has been estimated that approximately 60% of the population would need to use the NHSX application in order for it to be effective in reducing the spread of COVID-19. It is therefore crucial that we understand the level of, and factors influencing, uptake and engagement with digital tracing applications in order to put appropriate measures in place to mitigate those issues.AIMS1.To quantify the current data on COVID-19 digital contact tracing applicationsa.Uptake and engagement of COVID-19 digital contact tracing applicationsb.Examine whether uptake differs between countries c.Identify any predictors or correlates of uptake and engagement2.To conduct two scoping reviews to identify key barriers and facilitators influencing engagement and uptake of a.COVID-19 digital contact tracing applications b.Health behaviour change applications, including government approved applications, from academic literature and behaviour change guidelinesCONCLUSIONS•There is no evidence on the level of uptake and engagement with COVID-19 digital contact tracing applications.•There is a dearth of evidence regarding the barriers and facilitators to uptake and engagement with COVID-19 digital contact tracing applications.•The health behaviour change literature suggests a number of barriers and facilitators associated with uptake and engagement with applications.

BackgroundQualitative olfactory (smell) dysfunctions are a common side effect of post-viral illness and known to impact on quality of life and health status. Evidence is emerging that taste and smell loss are common symptoms of Covid-19 that may emerge and persist long after initial infection. The aim of the present study was to document the impact of post Covid-19 alterations to taste and smell.MethodsWe conducted passive and active thematic analysis of user-generated text from 9000 users of the AbScent Covid-19 Smell and Taste Loss moderated Facebook support group from March 24 to 30th September 2020.ResultsParticipants reported difficulty understanding, explaining and managing altered taste and smell; a lack of interpersonal and professional explanation or support; altered eating; appetite loss, weight change; loss of pleasure in food, eating and social engagement; altered intimacy and an altered relationship to self and others.ConclusionsOur findings suggest altered taste and smell with Covid-19 lead to a severe disruption to daily living that impacts on psychological well-being and health. Moreover, this impact is broad, spanning flavour perception; desire and ability to eat and prepare food; weight gain, loss and nutritional sufficiency; emotional wellbeing; professional practice; intimacy; social bonding and erosion of people’s very sense of reality. Our findings should inform the training, assessment and treatment practices of health care professionals working with long Covid.

A systematic review and qualitative synthesis of the experience of living with colorectal cancer as a chronic illness.

This paper reinforces the value of visceral geographic approaches to health research as a method 'beyond talking'. The paper establishes and sets out an integrative embodied multi-sensory research methodology-food play. Researchers across the social sciences and sciences are exploring the limits of logo and researcher centric research methods and exploring peoples sensory experience of themselves and the wider world using participatory, patient-centred, multi-sensory, visceral and biosocial geographic approaches. With reference to the growing interest in visceral approaches to research in geography, and sensory research in neurology, anthropology and embodied cognition in psychology, we argue that the presence and pungency of food uniquely animates research, and for our research, provided highly individualised insight into the lived experience of living long term with eating difficulties, allowing visceral difference to emerge and be expressed. We illustrate our approach with reference to a six-year research project, Resources for Living, co-produced with survivors of head and neck cancer and underpinned by a series of food play workshops to address post-treatment and chronic difficulties with food and eating.
