Abstract: This systematic review aimed to describe behaviour change theories and techniques used to inform nutrition interventions for adults undergoing bariatric surgery. A systematic search was conducted across PubMed, PsycInfo, CENTRAL, EMBASE and CINAHL from inception until 09 March 2021. Eligible studies were randomised controlled trials involving nutrition interventions performed by a healthcare provider, to adults that were waitlisted or had undergone bariatric surgery and received a nutrition intervention explicitly informed by one or more behaviour change theories or behaviour change techniques. Screening was conducted independently by two authors. Behaviour change techniques were examined using the behaviour change technique taxonomy version one which includes 93 hierarchical techniques clustered into 16 groups. Quality of included studies was assessed using Cochrane risk of bias 2.0. Twenty‐one publications were included, involving 15 studies and 14 interventions, with 1495 participants. Bias was low or had some concerns. Two interventions reported using behaviour change theories (transtheoretical model and self‐determination theory). Thirteen behaviour change technique taxonomy groupings and 29 techniques were reported across 14 interventions. Common techniques included ‘1.2 Problem solving’ ( n = 9 studies), ‘3.1 Social support (unspecified)’ ( n = 9 studies), ‘1.1 Goal setting (behaviour)’ ( n = 6 studies) and ‘2.3 Self‐monitoring of behaviour’ ( n =‐ 6 studies). While behaviour change techniques have been included, behaviour change theory is not consistently reported and/or adopted to inform nutrition interventions for adults undergoing bariatric surgery. Integrating behaviour change theory and techniques in nutrition interventions is important for researchers and bariatric surgery teams, including dietitians, to effectively target behaviours for this population.

Abstract: Interventions to prevent excessive weight gain after liver transplant are needed. The purpose of the present study was to enhance a specialist post-transplant well-being program through knowledge exchange with end-users. The study used an interactive process of knowledge exchange between researchers, clinicians and health system users. Data were collected as focus groups or telephone interviews and underwent applied thematic analysis. There were 28 participants (age 24-68 years 64% male). The results identified experiences that may influence decisions around health behaviours during the course of transplant recovery. Three over-arching themes were identified that impact on liver transplant recipients post-transplant health behaviours. These include (i) Finding a coping mechanism which highlighted the need to acknowledge the significant emotional burden of transplant prior to addressing long-term physical wellness (ii) Back to Life encompassing the desire to return to employment and prioritise family, while co-ordinating the burden of ongoing medical monitoring and self-management and (iii) Tailored, Personalised Care with a preference for health care delivery by transplant specialists via a range of flexible eHealth modalities. This person-centred process of knowledge exchange incorporated experiences of recipients into service design and identified life priorities most likely to influence health behaviours post-transplant. Patient co-creation of services has the potential to improve the integration of knowledge into health systems and future directions will require evaluation of effectiveness and sustainability of patient-centred multidisciplinary service development.

Abstract: To explore how stakeholders in rehabilitation conceptualise ‘successful rehabilitation’, to inform the development of a minimum dataset and core outcomes for sub-acute rehabilitation. Qualitative consensus study using the nominal group technique. Online focus groups. Consumer representatives ( n = 7), clinicians ( n = 15), and health service managers ( n = 9) from Australia. Participants responded to the question, ‘What does successful rehabilitation look like?’. Following item generation, they prioritised their top five responses, allocating 100 points across items to denote relative importance. Prioritised responses were analysed across stakeholder groups using qualitative content analysis. Ten themes were identified. ‘Successful rehabilitation’ is: (1) person and family centred (2) effective (3) inter-professional (4) accessible (5) goal oriented with meaningful outcomes (6) connected to the continuum of care (7) evidence-based and supportive of innovation and research (8) appropriately funded and skilled (9) satisfying and engaging and (10) safe. Stakeholder-defined ‘successful rehabilitation’ aligned with principles of value-based care and evidence-based rehabilitation. Provision and receipt of person and family centred care was the most important indicator of successful rehabilitation. Measures of success should include indicators of structure, process, outcome, and experience, and be conducted at multiple time-points.

Abstract: Dietary modification and exercise are encouraged to address cardiometabolic risk factors after solid organ transplantation. However, the lived experience of attempting positive lifestyle changes for liver transplant recipients is not known. The aim of this study was to explore the experiences of liver transplant recipients and their perspectives of a 12-week telehealth lifestyle programme and assess the feasibility of this innovative health service. Focus groups and one-on-one interviews were conducted with participants who had completed a 12-week, group-based, telehealth-delivered diet and exercise programme and thematic qualitative analysis was used to code and theme the data. In total, 19 liver transplant recipients participated in the study (25–68 years, median time since transplant 4.4 years, 63% male). Overarching themes included: (a) ‘broad telehealth advantages' which highlighted that telehealth reduced the perceived burdens of face-to-face care (b) ‘impact of employment' which identified employment as a competing priority and appeared to effect involvement with the programme (c) ‘adapting Mediterranean eating pattern to meet in idual needs' which identified the adaptability of the Mediterranean diet supported by sessions with the dietitian (d) ‘increasing exercise confidence' which recognised that a tailored approach facilitated confidence and acceptability of the exercise component of the programme. A telehealth lifestyle programme delivered by dietitians and exercise physiologists is an acceptable alternative to face-to-face care that can meet the needs of liver transplant recipients. There is a need to further innovate and broaden the scope of routine service delivery beyond face-to-face consultations.

Abstract: The metabolic syndrome is common across many complex chronic disease groups. Advances in health technology have provided opportunities to support lifestyle interventions. The purpose of this study is to test the feasibility of a health technology-assisted lifestyle intervention in a patient-led model of care. The study is a single-center, 26-week, randomized controlled trial. The setting is specialist kidney and liver disease clinics at a large Australian tertiary hospital. The participants will be adults with a complex chronic condition who are referred for dietetic assessment and display at least one feature of the metabolic syndrome. All participants will receive an in idualized assessment and advice on diet quality from a dietitian, a wearable activity monitor, and standard care. Participants randomized to the intervention group will receive access to a suite of health technologies from which to choose, including common base components (text messages) and optional components (online and mobile app–based nutrition information, an online home exercise program, and group-based videoconferencing). Exposure to the optional aspects of the intervention will be patient-led, with participants choosing their preferred level of engagement. The primary outcome will be the feasibility of delivering the program, determined by safety, recruitment rate, retention, exposure uptake, and telehealth adherence. Secondary outcomes will be clinical effectiveness, patient-led goal attainment, treatment fidelity, exposure demand, and participant perceptions. Primary outcome data will be assessed descriptively and secondary outcomes will be assessed using an analysis of covariance. This study will provide evidence on the feasibility of the intervention in a tertiary setting for patients with complex chronic disease exhibiting features of the metabolic syndrome. The study was funded in 2019. Enrollment has commenced and is expected to be completed by June 2022. Data collection and follow up are expected to be completed by December 2022. Results from the analyses based on primary outcomes are expected to be submitted for publication by June 2023. The study will test the implementation of a health technology–assisted lifestyle intervention in a tertiary outpatient setting for a erse group of patients with complex chronic conditions. It is novel in that it embeds patient choice into intervention exposure and will inform health service decision-makers in regards to the feasibility of scale and spread of technology-assisted access to care for a broader reach of specialist services.

Abstract: Digital health interventions may facilitate management of chronic conditions however, no reviews have systematically assessed the effectiveness of dietary interventions delivered by digital health platforms for improving dietary intake and clinical outcomes for adults with diet‐related chronic conditions. Databases CINAHL, CENTRAL, Embase and MEDLINE were searched from inception to April 2021 to identify controlled trials for dietary education delivered by digital health (mobile or electronic health) to adults with diet‐related chronic conditions. Random effects analysis was performed for diet quality, food groups, nutrients and clinical outcomes. Screening, data extraction and quality checking were completed in duplicate. Thirty‐nine studies were included involving 7333 participants. Significant changes were found for Mediterranean diet adherence score (standardised mean difference [SMD] = 0.79 95% confidence interval [CI] = 0.18 to 1.40), overall fruit and vegetable intake (mean difference [MD]: 0.63 serves/day 95% CI = 0.27–0.98), fruit intake alone (MD = 0.58 serves/day 95% CI = 0.39 to 0.77) and sodium intake (SMD = −0.22 95% CI = −0.44 to −0.01). Improvements were also found for waist circumference [MD = −2.24 centimetres 95% CI = −4.14 to −0.33], body weight (MD = −1.94 kg 95% CI = −2.63 to −1.24) and haemoglobin A1c (MD = −0.17% 95% CI = −0.29 to −0.04). Validity of digital assessment tools to measure dietary intake were not reported. The quality of evidence was considered to have low to moderate certainty. Modest improvements in diet and clinical outcomes may result from intervention via digital health for those with diet‐related chronic conditions. However, additional robust trials with better reporting of digital dietary assessment tools are needed to support implementation within clinical practice.

Abstract: To determine the perspectives to the adoption, scale-up, sustainability, and spread of technology-supported models of nutrition care, in hospital and ambulatory care settings. Thirty-one health service providers participated in in idual semi-structured interviews from a tertiary health service in Queensland, Australia. The Non-adoption, Abandonment, and challenges to the Scale up, Spread and Sustainability (NASSS) framework, designed to evaluate technology-supported models’ success, informed the qualitative design. Key findings were that technology-supported models of care could benefit many chronic condition patient groups dietitians are well suited to adopting this technology: and the value proposition in creating efficiency gains in the health service. However, challenges of transitioning and sustainability were identified. Perceived enablers for technology supported models of care included: previous intentions for technology supported models of care prior to the 2019 novel coronavirus pandemic opportunity for clinicians to complete higher valued tasks and integration of technology systems and assisted staff roles. Perceived barriers included: suitability for patients is dependent on experience and ability to use technology, varied confidence by clinicians when conducting clinical assessments high investment required for set up and ongoing maintenance and patients desire for adopting face-to-face care over technology. Health service providers perceived that embedding and adapting such models requires maintenance of high-quality service and continued research. Health service providers recognize adopting, scaling, and sustaining technology-supported models of nutrition care benefits patients, clinicians, and health services in general. Robust clinical trials and health service evaluations of technology-supported models of care, across practice settings are now needed.

Abstract: Soil acidity and waterlogging increase manganese (Mn) in leaf tissues to potentially toxic concentrations, an effect reportedly alleviated by increased silicon (Si) and phosphorus (P) supply. Effects of Si and P on Mn toxicity were studied in four plant species using synchrotron-based micro X-ray fluorescence (μ-XRF) and nanoscale secondary ion mass spectrometry (NanoSIMS) to determine Mn distribution in leaf tissues and using synchrotron-based X-ray absorption spectroscopy (XAS) to measure Mn speciation in leaves, stems and roots. A concentration of 30 μM Mn in solution was toxic to cowpea and soybean, with 400 μM Mn toxic to sunflower but not white lupin. Unexpectedly, μ-XRF analysis revealed that 1.4 mM Si in solution decreased Mn toxicity symptoms through increased Mn localization in leaf tissues. NanoSIMS showed Mn and Si co-localized in the apoplast of soybean epidermal cells and basal cells of sunflower trichomes. Concomitantly, added Si decreased oxidation of Mn(II) to Mn(III) and Mn(IV). An increase from 5 to 50 μM P in solution changed some Mn toxicity symptoms but had little effect on Mn distribution or speciation. We conclude that Si increases localized apoplastic sorption of Mn in cowpea, soybean and sunflower leaves thereby decreasing free Mn

Abstract: To explore patients' experiences with rehabilitation, with a particular focus on outcomes that are perceived to be of value. Semi structured interviews were conducted with adults who recently had rehabilitation for a chronic health condition in a hospital or community setting. Banja's definition of rehabilitation (personally fulfilling, socially meaningful and functionally effective) informed the enquiry and interpretation of the findings. Thematic analysis was used to categorise the data into codes and themes. 16 people (40-84 years, 69% male, People who undertake rehabilitation express erse expectations when assessing their outcomes and progress, although common elements could be identified. Participants valued a number of key features about the delivery and evaluation of their rehabilitation. These features revolved around the personalisation of the process and having clarity about progress.Implications for rehabilitationRehabilitation therapists should encourage ongoing personalised discussions about progress to promote clear and shared understanding of what clients and therapists expect, alongside the use of current available measures.Rehabilitation therapists should consider providing opportunities for participants to self-reflect about their experiences and modify their goals based on personal progress and deeper understanding of their circumstances.Rehabilitation therapists should consider assessing the extent to which the in idual feels satisfied with and capable of achieving these outcomes before departing from the rehabilitation service.Overall, rehabilitation teams should think about spending more time with the patient to prioritise and understand their in idual goals and values.
