RESUMEN

Atopic dermatitis (AD) is a chronic, pruritic and inflammatory, dry skin condition with many known comorbidities. These include airway disease, food allergies, atopic eye disease and autoimmune conditions. Furthermore, there is often significant sleep disturbance as well as increased psychological distress and mental health problems. Severe AD therefore often has a significant impact on the quality of life of both patients and their families. In this review we discuss recent findings on the putative links between AD, its association with itch, sleep disturbance and neuropsychiatric morbidity, including the role of inflammation in these conditions. Itch was thought to predominantly drive sleep disruption in AD. We now understand changes in sleep influence immune cell distribution and the associated inflammatory cytokines, which suggests a bidirectional relationship between AD and sleep. We also increasingly recognize inflammation as a key driver in psychological symptoms and disorders. The link between cutaneous, systemic and possible brain inflammation could at least in part be driven by the sleep deprivation and itch-driven neuronal proliferation seen in AD.

RESUMEN

PURPOSE: Occupational biomechanical factors are implicated in the aetiology and progression of low back pain (LBP). This study cross-culturally adapted and psychometrically investigated the Occupational Risk Factor Questionnaire (ORFQ) in a low literate Nigerian Igbo population with chronic LBP. METHODS: Forward and back translation of the original ORFQ by clinical and non-clinical translators was followed by an expert committee review. The adapted ORFQ was pre-tested amongst rural Nigerian adults with chronic LBP using cognitive think-aloud interviewing. Internal consistency (Cronbach's alpha) and test-retest reliability (unweighted and linear weighted k statistic for item-by-item agreement, and intra-class correlation coefficient-ICC) were investigated amongst 50 rural and urban Nigerian dwellers with chronic LBP. Spearman's correlation and regression analyses were conducted with the Igbo-ORFQ, and measures of disability [World Health Organisation Disability Assessment Schedule (WHODAS 2.0), Roland Morris Disability Questionnaire (RMDQ), Back performance scale (BPS)], pain intensity [Eleven-point box scale (BS-11)] and social support [Multidimensional Scale of Perceived Social Support (MSPSS)], to test construct validity with 200 rural Nigerian dwellers with chronic LBP. RESULTS: Cross-cultural adaptation highlighted difficulty conceptualising and concretising exposure to biomechanical risk factors. Item-by-item agreement, internal consistency (α = 0.84) and intraclass correlation coefficient (ICC = 0.83) were good. Some unexpected direction of associations between the biomechanical components of the Igbo-ORFQ, and disability, pain intensity, and social support prohibits establishment of construct validity. CONCLUSION: Prospective studies comparing the Igbo-ORFQ to other measures of exposure to occupational biomechanical risk factors are required to establish the construct validity of the Igbo-ORFQ.

RESUMEN

Social learning can reduce the costs associated with trial-and-error learning. There is speculation that social learning could contribute to trap and bait avoidance in invasive species like the common brushtail possum (Trichosurus vulpecula)-a marsupial for which social learning has not previously been investigated. In large outdoor pens, we presented wild-caught 'demonstrator' possums with puzzle devices containing an attractive food reward; 2 of 8 demonstrators accessed the reward the first night the puzzle was presented and another three succeeded on later nights. Meanwhile, 'observer' possums in adjacent pens watched the demonstrators for five nights and then were given the opportunity to solve the puzzle themselves; 15 of 15 succeeded on their first night (a highly significant improvement). This experiment thus provides strong evidence of social learning by common brushtail possums. Future research should investigate whether information about aversive stimuli (such as traps and toxic baits) can similarly be transmitted between possums by social learning; if so, this could have important implications for possum pest control.

RESUMEN

BACKGROUND: Exercise adherence is important for achieving a long-term effect from musculoskeletal management. The Exercise Adherence Rating Scale (EARS), which was developed in 2017 as a patient reported outcome measure to assess exercise adherence in those with chronic low back pain in the UK, has demonstrated acceptable validity and reliability and is a robust measure of exercise adherence. This study aimed to undertake cross-cultural adaptation of the EARS into Japanese and investigate its structural validity in participants with musculoskeletal disorders. METHODS: The current study was composed of two phases, where a provisional Japanese version of the EARS was developed employing an international guideline for cross-cultural adaptation (Phase A), and structural validity was then evaluated using the Rasch analysis (Phase B). Participants with musculoskeletal disorders who have individualized home exercises prescribed by a physical therapist were recruited. RESULTS: In Phase A, the pilot testing was conducted twice because the initial testing detected some uncertainty revealed in comments from 17 participants (5 males and 12 females, 18-79 years of age) about which activities and exercises were supposed to be included. We therefore modified the draft by identifying a person who prescribed/recommended activities and exercises as per the Working Alliance Inventory. The second pilot testing using this draft recruited 30 participants (6 males and 24 females, 18-79 years of age), who provided no further comments, demonstrating the Japanese version of the EARS (EARS-J) had been successfully developed. In Phase B, data from 200 participants who completed the EARS-J (63 males and 127 females, mean ± SD of age = 53.6 ± 17.0) were analyzed using the Andrich's Rating Scale Model. Rasch statics indicated unidimensionality of the six items of the EARS-J. The Cronbach α was 0.77. Substantial ceiling effect (21.0%) was observed, with no floor effect (0.5%). CONCLUSIONS: A Japanese version of the EARS has been developed, which demonstrated acceptable structural validity with the evidence of unidimensionality in the Rasch analysis in Japanese people with musculoskeletal disorders who were prescribed individualized home exercises. However, there was a substantial ceiling effect and further studies are required to comprehensively establish validity and reliability of the EARS-J.

RESUMEN

OBJECTIVE: This study aimed to assess the feasibility of online Acceptance and Commitment Therapy for painful diabetic neuropathy in the United Kingdom and to determine if a larger randomized controlled trial testing treatment efficacy is justified. METHODS: Participants with painful diabetic neuropathy were recruited online and from hospital services. This was a single-arm study in which all participants received online Acceptance and Commitment Therapy. Participants completed questionnaires at baseline and three months post-treatment. Primary feasibility outcomes were recruitment, retention, and treatment completion rates. Secondary outcomes were pre- to post-treatment effects on pain outcomes and psychological flexibility. RESULTS: Of 225 potentially eligible participants, 30 took part in this study. Regarding primary feasibility outcomes, the treatment completion and follow-up questionnaire completion rates were 40% and 100%, respectively. Generally, at baseline those who completed the treatment, compared with those who did not, had better daily functioning and higher psychological flexibility. With respect to secondary outcomes, results from the completers group showed clinically meaningful effects at post-treatment for 100% of participants for pain intensity and pain distress, 66.7% for depressive symptoms, 58.3% for functional impairment, 41.7% for cognitive fusion, 66.7% for committed action, 58.3% for self-as-context, and 41.7% for pain acceptance. CONCLUSIONS: This preliminary trial suggests feasibility of recruitment and follow-up questionnaire completion rates, supporting planning for a larger randomized controlled trial. However, treatment completion rates did not achieve the prespecified feasibility target. Changes to the treatment content and delivery may enhance the feasibility of online Acceptance and Commitment Therapy for people with painful diabetic neuropathy on a larger scale.

RESUMEN

BACKGROUND: Rural Nigeria has one of the greatest burdens of low back pain but there are no effective evidence-based interventions to manage it in this population. This paper presents the application of the intervention mapping (IM) approach in the development of a complex behavior change intervention - The Good Back program, aimed at reducing non-specific chronic low back pain (CLBP) disability in rural Nigeria. METHODS: The first four steps of IM were applied. A critical review of the literature, 2 qualitative studies and a population-based cross-sectional study in rural Nigeria helped to identify two key program objectives in order to reduce CLBP disability in this population: reduce the impact of illness perceptions, fear avoidance beliefs, catastrophising, anxiety and depression by targeting maladaptive illness perceptions about CLBP; and facilitate the adoption of exercises and good posture to limit disability. A systematic review plus these studies, identified the personal and environmental determinants of the performance objectives including health literacy, self-awareness, self-efficacy, personal preference, health professional skills, health facility structure and family/community support. The theory, techniques and strategies for modifying personal and environmental determinants were also identified from these studies. Intervention components and materials were then produced for practical application. The initial developed intervention was described. RESULTS: The feasibility and acceptability of the developed program was then tested using a small pragmatic non-randomised controlled study incorporating qualitative exit feedback interviews in a rural Nigerian primary health care centre. The program appeared feasible and acceptable when delivered by a highly trained physiotherapist. There were promising clinical outcomes in disability, pain intensity, illness perceptions, fear avoidance beliefs and pain medication use. Suggestions for program improvement included shorter but ongoing sessions, video demonstration of exercises/good posture, spacious exercise/demonstration rooms, and community legitimisation of exercise as treatment for back pain. Subsequent modifications to program content and delivery were then described. Theoretical modification included the addition of aspects of the social cognitive theory to the Leventhal's self-regulatory model of illness cognitions. CONCLUSIONS: IM appears to be a suitable framework for designing complex behavior change interventions in rural Nigeria. The need for further testing of the intervention was highlighted.

RESUMEN

BACKGROUND: Globally, the leading cause of years lived with disability is low back pain (LBP). Chronic low back pain (CLBP) is responsible for most of the cost and disability associated with LBP. This is more devastating in low income countries, particularly in rural Nigeria with one of the greatest global burdens of LBP. No Igbo back pain specific measure captures remunerative or non-remunerative work outcomes. Disability measurement using these tools may not fully explain work-related disability and community participation, a limitation not evident in the World Health Organisation Disability Assessment Schedule (WHODAS 2.0). This study aimed to cross-culturally adapt the WHODAS 2.0 and validate it in rural and urban Nigerian populations with CLBP. METHODS: Translation, cultural adaptation, test-retest, and cross-sectional psychometric testing was performed. WHODAS 2.0 was forward and back translated by clinical/non-clinical translators. Expert review committee evaluated the translations. Twelve people with CLBP in a rural Nigerian community piloted/pre-tested the questionnaire. Cronbach's alpha assessing internal consistency; intraclass correlation coefficient and Bland-Altman plots assessing test-retest reliability; and minimal detectable change were investigated in a convenience sample of 50 adults with CLBP in rural and urban Nigeria. Construct validity was examined using Spearman's correlation analyses with the back-performance scale, Igbo Roland Morris Disability Questionnaire and eleven-point box scale; and exploratory factor analysis in a random sample of 200 adults with CLBP in rural Nigeria. Ceiling and floor effects were investigated in both samples. RESULTS: Patient instructions were also translated. 'Waist pain/lower back pain' was added to 'illness(es)' to make the measure relevant for this study whilst allowing for future studies involving other conditions. The Igbo phrase for 'family and friends' was used to better represent 'people close to you' in item D4.3. The Igbo-WHODAS had good internal consistency (α = 0.75-0.97); intra class correlation coefficients (ICC = 0.81-0.93); standard error of measurements (5.05-11.10) and minimal detectable change (13.99-30.77). Igbo-WHODAS correlated moderately with performance-based disability, self-reported back pain-specific disability and pain intensity, with a seven-factor structure and no floor and ceiling effects. CONCLUSIONS: Igbo-WHODAS appears psychometrically sound. Its research and clinical utility require further testing.

RESUMEN

BACKGROUND: This study aimed to adapt the Exercise Adherence Rating Scale (EARS) into Brazilian Portuguese and evaluate its measurement properties, given as reliability, validity, and responsiveness in patients with non-specific Chronic Low Back Pain (CLBP). METHODS: A total of 108 patients with a mean age of 46.62 years (SD = 9.98) and CLBP participated in this longitudinal study. Participants were oriented on undertaking the prescribed exercises in the first session, and adherence behavior was assessed after 1 week, and finally reassessed after 2 weeks (test-retest reliability). Three weeks after the first assessment, they were invited again to full fill the EARS (responsiveness). The intraclass correlation coefficient (ICC2,1) and Cronbach's α were used to assess test-retest reliability and internal consistency, respectively. Spearman's correlation and confirmatory factor analysis (CFA) were used to assess construct validity, and the Receiver operating characteristic curve and area under the curve (AUC) were used to analyze responsiveness. RESULTS: The one-factor EARS-Br (adherence behavior) structure with 6 items showed acceptable fit indexes (comparative fit index and goodness of fit index> 0.90 and root-mean-square error of approximation< 0.08). The EARS-Br scale showed acceptable internal consistency (α = 0.88) and excellent reliability (ICC = 0.91 [95% CI 0.86-0.94]). Mild to moderate correlations were observed between EARS-Br total score vs. disability, pain catastrophizing, depression/anxiety, fear-avoidance and pain intensity. A Minimally Important Change (MIC) of 5.5 in the EARS-Br total score was considered as a meaningful change in the adherence behavior (AUC = 0.82). Moderate accuracy (AUC = 0.89) was obtained for a 17/24 total EARS cutoff score after home exercise was prescribed. The sensitivity and specificity were also acceptable (greater than 80%). CONCLUSION: Our results demonstrated acceptable EARS-Br reliability, validity, and responsiveness for patients with CLBP. A final score of 17/24 on EARS after the prescription of home-exercise could be used as a cut-off for an acceptable adherence behavior associated with improvement in patient outcomes.

RESUMEN

BACKGROUND: There are currently no client generated measures able to capture a child's perspective of the value of generic therapeutic mental health interventions. We have developed a new measure called 'PSYCHLOPS Kids'. It measures areas of individual importance to the respondent and contains both quantitative and qualitative elements. We aimed to pilot this new outcome measure and determine its psychometric properties. METHODS: PSYCHLOPS Kids was adapted from the adult PSYCHLOPS questionnaire, a validated and reliable client-generated measure used in primary care mental health. Development of PSYCHLOPS Kids involved an expert group, pilot testing with dramatherapists followed by psychometric testing with children receiving dramatherapy aged 7-13 years. RESULTS: One hundred and thirty-two children completed pre- and postintervention questionnaires. Mean initial PSYCHLOPS Kids scores (scale of 0-12) were 4.98 (SD: 3.42); mean post-therapy, 3.24 (SD: 3.03); mean effect size of change, 0.51. The Strengths and Difficulties Questionnaire (SDQ) was used as a comparator instrument completed by parent/carers of 32 children; mean effect size, 0.39. The effect size difference between both instruments was not significant (t = 1.05; p = .30); the PSYCHLOPS Kids Problem domain effect size (mean, 0.68) was significantly greater than for the SDQ (t = 2.06; p = .04). Concurrent validity was demonstrated by strong predictive power of change scores for the self-assessment of change item in PSYCHLOPS Kids; therapist-assessment of change was not a significant predictor of change scores. PSYCHLOPS Kids and SDQ change scores were not significantly correlated. CONCLUSIONS: PSYCHLOPS Kids is the first client generated mental health outcome measure focussing on problems for generic use in children. It has demonstrated moderate responsiveness to change and satisfactory testing for measured aspects of validity and reliability. PSYCHLOPS Kids now requires further validity, reliability and qualitative testing.

RESUMEN

AIMS: Circus is a physically demanding profession, but injury and help-seeking rates tend to be low. This qualitative interview study explored the perceptions and beliefs about injury and help-seeking of circus artists. METHODS: Ten professional circus artists (5 males, 5 females; mean age 33 yrs, range 27-42) were enrolled. Individual, semi-structured interviews were conducted until data saturation of themes was reached. Data were analysed thematically. FINDINGS: Four themes were identified: 1) the injured artist; 2) professionalism; 3) circus life; and 4) artists' experience of healthcare. Most participants described the circus as central to their lives, and injuries had wide-ranging psychosocial consequences. Injury adversely affected participants' mood and threatened their identity. Situational and personal factors (e.g., the belief that pain was normal) pushed participants to use adaptive strategies to perform when injured. Continuous touring and financial constraints affected help-seeking. Easy access to healthcare was rare and participants often self-managed injuries. Experiences of healthcare varied, and participants desired flexible and accessible approaches to prevention and injury management. A modified version of the integrated model of psychological response to injury and rehabilitation process and the concept of identity provided a framework to understand participants. CONCLUSION: Injuries had extensive negative consequences. Work schedules, financial factors, employer support, the artist's perception of the importance of the show, and the relationship between circus and identity influenced injury management and help-seeking. Injury prevention and management strategies could be optimised by developing centres of expertise, online resources, and better regulations of the profession.

RESUMEN

OBJECTIVE: To develop and validate the Pediatric Vestibular Symptom Questionnaire (PVSQ) and quantify subjective vestibular symptom (ie, dizziness, unsteadiness) severity in children. STUDY DESIGN: One hundred sixty-eight healthy children (female, n = 91) and 56 children with postconcussion dizziness or a vestibular disorder (female, n = 32), between ages 6 and 17 years, were included. The PVSQ contains questions regarding vestibular symptom frequency during the previous month. The Strengths and Difficulties Questionnaire (SDQ), a brief behavioral screening instrument, was also completed. RESULTS: The PVSQ showed high internal consistency (10 items; Cronbach α = 0.88). A significant between-group difference was noted with higher (ie, worse) PVSQ scores for children with vestibular symptoms (P < .001); no significant differences were noted between patient groups. The optimal cut-off score for discriminating between individuals with and without abnormal levels of vestibular symptoms was 0.68 out of 3 (sensitivity 95%, specificity 85%). Emotional and hyperactivity SDQ subscale scores were significantly worse for patients compared with healthy participants (P ≤ .01). A significant relationship was noted between mean PVSQ and SDQ (parent-rated version) hyperactivity and total scores for patients (P ≤ .01) and the SDQ (self-rated) emotional, hyperactivity, and total score (P ≤ .01) in healthy controls. However, mean SDQ subscale and total scores were within normal ranges for both groups. CONCLUSIONS: Self-reported vestibular symptoms, measured by the PVSQ, discriminated between children presenting with vestibular symptoms and healthy controls and should be used to identify and quantify vestibular symptoms that require additional assessment and management.

RESUMEN

UNLABELLED: Chromosomal microarray testing (CMA) generally aids paediatric genetic diagnosis. However, pre-CMA counselling is important as results can be ambiguous, generate uncertainty and raise ethical issues. We developed standards for counselling and giving families results; using these we evaluated practice for children seen by the Auckland Developmental Paediatric team in 2011. Pretest discussion was documented in 14 of 28 subjects and potential outcomes in 4of 28. 8 of 28 received information leaflets, 1 of 28 gave signed consent. 3 of 3 with abnormal results and 4 of 5 with variants of unknown significance (VOUS) were offered clinical genetics referral. 8 of 20 families with normal results were written to; two with abnormal results were informed face-to-face and one in writing; most VOUS were communicated by phone, voicemail or letter. CONCLUSION: CMA testing requires clear patient information sheets and in-depth pretest discussion for informed consent, timely feedback of results and genetics referral as appropriate. Authoritative guidelines and training are needed to strengthen CMA counselling.

RESUMEN

Asymmetrical segregation of differentiated sister chromatids is thought to be important for cellular differentiation in higher eukaryotes. Similarly, in fission yeast, cellular differentiation involves the asymmetrical segregation of a chromosomal imprint. This imprint has been shown to consist of two ribonucleotides that are incorporated into the DNA during lagging-strand synthesis in response to a replication pause, but the underlying mechanism remains unknown. Here we present key novel discoveries important for unravelling this process. Our data show that cis-acting sequences within the mat1 cassette mediate pausing of replication forks at the proximity of the imprinting site, and the results suggest that this pause dictates specific priming at the position of imprinting in a sequence-independent manner. Also, we identify a novel type of cis-acting spacer region important for the imprinting process that affects where subsequent primers are put down after the replication fork is released from the pause. Thus, our data suggest that the imprint is formed by ligation of a not-fully-processed Okazaki fragment to the subsequent fragment. The presented work addresses how differentiated sister chromatids are established during DNA replication through the involvement of replication barriers.

RESUMEN

Background: Fibromyalgia (FM) is a chronic pain disorder characterised by widespread pain, fatigue and cognitive symptoms. Acceptance and commitment therapy (ACT) aims to improve psychological flexibility and has been found to be beneficial in treating chronic pain; however, there are few studies evaluating its efficacy in treating FM. Aim: This systematic review and meta-analysis evaluated the efficacy of acceptance and commitment therapy in patients with fibromyalgia. Methods: PubMed, Embase and PsychInfo databases were searched. Randomised Controlled Trials (RCTs) were eligible for inclusion if participants had FM, and the intervention was based on the ACT framework/model, and not combined with any other active therapy; any non-ACT control was accepted. A meta-analysis was performed, with the primary outcomes pain acceptance (chronic pain acceptance questionnaire, CPAQ), health-related quality of life (fibromyalgia impact questionnaire, FIQ), attrition rate and frequency of adverse events, and the secondary outcomes pain intensity, disability, depression, anxiety, and fatigue. Results: Six RCTs, with a total of 384, mostly-female, participants were included, with ACT being delivered online, in a group setting, or one-to-one. ACT was superior to controls in improving FIQ score at post-intervention (SMD -1.05, 95% CI -2.02, -0.09) and follow-up (SMD -1.43, 95% CI -2.17, -0.69) and CPAQ post-intervention (SMD 1.05, 95% CI 0.61, 1.49) and at follow-up (SMD 0.95, 95% CI 0.40, 1.49). Attrition was below 20% in 4/6 studies and no adverse events were reported as attributable to ACT. All secondary outcomes showed large-to-moderate pooled effect estimates post-intervention, indicating improvement in anxiety, depression, pain and disability. Fatigue also improved, with a large negative effect. Conclusions: The results suggest ACT improved outcomes in patients with FM: there was an overall improvement in all outcomes post-intervention, with most maintained at follow-up. This review was, however, limited by the small body of evidence and differing methodologies of included studies.

RESUMEN

OBJECTIVE: To evaluate the efficacy of remotely delivered motivational conversations on health outcomes in musculoskeletal populations. METHODS: Four electronic databases (inception-March 2022) were searched and combined with grey literature. Randomised control trials (RCTs) evaluating the effect of remotely delivered motivational conversation-based interventions within musculoskeletal populations, using valid measures of pain, disability, quality of life (QoL), or self-efficacy were included. Overall quality was assessed using GRADE criteria. Meta-analyses were performed using random effects models with pooled effect sizes expressed as standardised mean differences ( ± 95%CIs). RESULTS: Twelve RCTs were included. Meta-analyses revealed very-low to moderate quality evidence that remote interventions have a positive effect on pain and disability both immediately post intervention and at long-term follow-up compared to control, and have a positive effect on self-efficacy immediately post intervention. There was no effect on QoL immediately post intervention or at long-term follow up. CONCLUSION: Remotely delivered motivation-based conversational interventions have a positive effect on pain, disability, and self-efficacy but not on QoL. PRACTICE IMPLICATIONS: Motivational conversations, delivered remotely, may be effective in improving some health-related outcomes in MSK populations. However, higher quality evidence is needed to determine optimal intervention durations, and dosing frequencies using sufficient sample sizes and follow-up time frames.

RESUMEN

PURPOSE: To investigate factors contributing to concerns about falling and activity restriction in the community among older adults who had a hip fracture. METHODS: A mixed method systematic review with a convergent segregated approach. We searched Medline, Embase, PsycInfo, PEDRo, CINAHL and the Cochrane library. Results were synthesised narratively considering physical, psychological, environmental, care, and social factors and presented in tables. Critical appraisal was completed in duplicate. RESULTS: We included 19 studies (9 qualitative, 9 observational, 1 mixed methods) representing 1480 individuals and 23 factors related to concerns about falling and activity restriction. Physical factors included falls history, comorbidities, balance, strength, mobility and functionality. Psychological factors included anxiety and neuroticism scores, perceived confidence in/control over rehabilitation and abilities, and negative/positive affect about the orthopaedic trauma, pre-fracture abilities and future needs. Environmental factors included accessibility in the home, outdoors and with transport. Social and care factors related to the presence or absence of formal and informal networks, which reduced concerns and promoted activity by providing feedback, advice, encouragement, and practical support. CONCLUSION: These findings highlight that to improve concerns about falling and activity restriction after hip fracture, it is important to: improve physical and functional abilities; boost self-confidence; promote positive affect; involve relatives and carers; increase access to clinicians, and; enhance accessibility of the home, outdoors and transport. Most factors were reported on by a small number of studies of varying quality and require replication in future research.

RESUMEN

BACKGROUND: Pulmonary rehabilitation (PR) is a programme of exercise and education and the most effective treatment for the symptoms and disability associated with chronic obstructive pulmonary disease. However, the benefits of PR are limited by poor uptake and completion. This trial will determine whether using trained volunteer lay health workers, called "PR buddies," improves uptake and completion of PR and is cost-effective. This trial protocol outlines the methods for evaluating effectiveness, cost-effectiveness, and acceptability. METHODS: The IMPROVE trial is a pragmatic, open, cluster randomised controlled trial planned in 38 PR services across England and Wales. PR services will be randomised to either intervention arm-offering support from PR buddies to patients with chronic obstructive pulmonary disease-or to usual care as the control arm. PR staff in trial sites randomised to the intervention arm will receive training in recruiting and training PR buddies. They will deliver training to volunteers, recruited from among people who have recently completed PR in their service. The 3-day PR-buddy training programme covers communication skills, confidentiality, boundaries of the PR-buddy role and behaviour change techniques to help patients overcome obstacles to attending PR. An internal pilot will test the implementation of the trial in eight sites (four intervention sites and four in control arm). The primary outcome of the trial is the uptake and completion of PR. A process evaluation will investigate the acceptability of the intervention to patients, PR staff and the volunteer PR buddies, and intervention fidelity. We will also conduct a cost-effectiveness analysis. DISCUSSION: Improving outcomes for chronic obstructive pulmonary disease and access to PR are priorities for the UK National Health Service (NHS) in its long-term plan. The trial hypothesis is that volunteer PR buddies, who are recruited and trained by local PR teams, are an effective and cost-effective way to improve the uptake and completion rates of PR. The trial is pragmatic, since it will test whether the intervention can be incorporated into NHS PR services. Information obtained in this trial may be used to influence policy on the use of PR buddies in PR and other similar services in the NHS. TRIAL REGISTRATION: ISRCTN12658458.

RESUMEN

BACKGROUND: A high proportion of patients do not regain outdoor mobility after hip fracture. Rehabilitation explicitly targeting outdoor mobility is needed to enable these older adults to recover activities which they value most. The overarching aim of this study is to determine the feasibility of a randomised controlled trial which aims to assess the clinical- and cost-effectiveness of an intervention designed to enable recovery of outdoor mobility among older adults after hip fracture (the OUTDOOR intervention). METHODS: This is a protocol for a multi-centre pragmatic parallel group (allocation ratio 1:1) randomised controlled assessor-blinded feasibility trial. Adults aged 60 years or more, admitted to hospital from- and planned discharge to- home, with self-reported outdoor mobility in the three-months pre-fracture, surgically treated for hip fracture, and who are able to consent and participate, are eligible. Individuals who require two or more people to support mobility on discharge will be excluded. Screening and consent (or consent to contact) will take place in hospital. Baseline assessment and randomisation will follow discharge from hospital. Participants will then receive usual care (delivered by physiotherapy, occupational therapy, or therapy assistants), or usual care plus the OUTDOOR intervention. The OUTDOOR intervention includes a goal-orientated outdoor mobility programme (supported by up to six in-person visits), therapist-led motivational dialogue (supported by up to four telephone calls), supported by a past-patient led video where recovery experiences are shared, and support to transition to independent ongoing recovery. Therapists delivering the OUTDOOR intervention (distinct from those supporting usual care) will receive training in motivational interviewing and behaviour change techniques. Baseline demographics will be collected. Patient reported outcome measures including health related quality of life, activities of daily living, pain, community mobility, falls related self-efficacy, resource use, readmissions, and mortality will be collected at baseline, 6-weeks, 12-weeks, and 6-months (for those enrolled early in the trial) post-randomisation. Exercise adherence (6- and 12- weeks) and intervention acceptability (12-weeks) will be collected. A subset of 20 participants will also support accelerometery data collection for 10 days at each time point. DISSEMINATION: The trial findings will be disseminated to patients and the public, health professionals and researchers through publications, presentations and social media channels. TRIAL REGISTRATION: The trial has been registered at ISRCTN16147125. PROTOCOL VERSION: 3.0.

RESUMEN

Objectives: The aims were to explore the nature of methods/techniques applied to improve adherence to physical activity (PA) and exercise in people with inflammatory arthritis and to identify whether studies were theory based and/or used behaviour change techniques (BCTs). Methods: Searches were undertaken of English language articles within four databases: Embase, Medline, PsycINFO and Cochrane. Articles were included if they assessed adherence to a PA and/or exercise intervention. A narrative synthesis of the findings is reported. Results: Of 1909 studies screened, 18 studies met inclusion criteria. Adherence was most frequently included as a secondary outcome. Reporting of adherence measures was poor, in that 13 studies did not use a validated measure of adherence, with only three validated measures being identified. The majority of studies were not theory driven (n = 13), although the health belief model was the most used theoretical framework (n = 5). Only two studies mentioned both theory and BCTs. Four studies reported components that were mapped onto BCTs, with goal setting being the most prevalent. Conclusion: This scoping review found that adherence to PA and/or exercise interventions was rarely the focus of research, despite its importance in maintaining health in people with inflammatory arthritis. Where research has been conducted in this area, serious shortcomings were revealed, in that psychological theory, evidence-based BCTs derived from theory and valid adherence measures were not used to inform intervention design and target adherence, meaning that interventions were suboptimal. These results suggest that there is considerable room for improvement and that more high-quality research is required to investigate determinants of adherence and develop impactful interventions.

RESUMEN

Objectives: A scoping review was selected to explore what non-pharmacological and non-invasive pain management interventions are available for individuals from Turkish-speaking ethnic groups with chronic pain and what represents the most appropriate intervention. Inclusion Criteria: Adults with non-malignant chronic pain from Turkish-speaking ethnic groups residing in or outside of Turkey. All non-pharmacological and non-invasive pain management interventions were considered. No limits were placed on geographic location, gender, sex or healthcare setting. Methods: The MEDLINE database was searched for published literature in April 2022. An English language filter was applied. No limits were placed on study design or date of publication. Data was charted from eligible studies into a data extraction table. Key concepts were identified during data extraction by DN. Results: Eleven studies were included in the final review. All were conducted within a quantitative research paradigm. The studies were completed in Turkey (7), Belgium (1), Sweden (1) and Switzerland (1). One was a multi-country review. No studies were conducted in the UK. The primary interventions were heterogenous and included: pain science education (2), cognitive behavioural therapy (2), transcranial magnetic stimulation (1), balneotherapy (1), extracorporeal shockwave therapy (1), transcutaneous electrical nerve stimulation (1), wool therapy (1), exercise and patient dialogues (1) and aromatherapy massage and reflexology (1). Location of pain, outcome measures and timings of follow-ups were heterogeneous. Conclusions: Intervention heterogeneity, exclusively quantitative methodology and absence of studies completed in the UK meant no conclusions could be made on what represents the most appropriate non-pharmacological and non-invasive interventions intervention for individuals from Turkish speaking ethnic groups with non-malignant chronic pain.
