RESUMO
RATIONALE: Major lower limb amputation (LLA, above the ankle) is performed for people with intractable pain, life-threatening infections, or non-functional limbs. Of 7500 LLAs carried out in England between 2015 and 2018, the majority of these were performed in dysvascular patients. Dysvascularity is the absence of adequate blood supply to maintain a limb's usual function (ischaemia, usually caused by peripheral arterial disease or diabetes mellitus), ultimately leading to pain and tissue injury (ulcers, gangrene, sometimes referred to as tissue loss). Among those who undergo dysvascular LLA, 5.7% and 11.5% will likely undergo contralateral LLA at one and five years respectively, which is associated with greater disability and lower likelihood of returning to work, increasing the psychological burden to the patient and socioeconomic cost to the patient and health service. While extensive research has been carried out in the management of peripheral arterial disease and the care of diabetic feet, there are no guidelines for practice on prevention of contralateral amputation. OBJECTIVES: To assess the effects of non-surgical interventions versus placebo, no intervention, or other non-surgical interventions on contralateral limb (CLL) tissue loss and amputation in dysvascular patients with a primary major LLA. SEARCH METHODS: The Cochrane Vascular Information Specialist searched the Cochrane Vascular Specialised Register, CENTRAL, MEDLINE, Embase, CINAHL and PEDro databases and the World Health Organization International Clinical Trials Registry Platform and ClinicalTrials.gov trials registers until 20 March 2023. We also checked the references of identified studies and contacted study authors and manufacturers of relevant products. ELIGIBILITY CRITERIA: We aimed to include all randomised controlled trials (RCTs) and quasi-RCTs (e.g. randomised by birthdate) comparing the effectiveness of a non-surgical intervention with placebo, no intervention, or other non-surgical intervention, in adults with a primary major LLA due to dysvascularity. Interventions could be physical, pharmacological, educational, behavioural, or organisational, and delivered by a healthcare professional or carer. OUTCOMES: Our critical and important outcomes of interest were as follows. Critical outcomes ⢠Incidence of new localised tissue injury or ulceration (tissue loss) of the CLL, regardless of stage or classification at given time points. ⢠Time to the development of any localised tissue injury or ulceration (tissue loss) of the CLL, regardless of stage or classification. ⢠Incidence of new minor amputation (through the ankle, foot, or toe(s)) of the CLL at given time points. ⢠Time to new minor amputation (through the ankle, foot, or toe(s)) of the CLL. ⢠Incidence of new major amputation (whole limb or partial limb, above the ankle) of the CLL at given time points. ⢠Time to new major amputation (whole limb or partial limb, above the ankle) of the CLL. Important outcomes ⢠Survival (time to death from all causes) at 12 months. ⢠Patient-reported outcome measures of health-related quality of life (HRQoL) using validated scales such as the 12-item Short Form Health Survey (SF-12) and EQ-5D. ⢠Adverse events (e.g. infections in the CLL). ⢠Hospital readmission. RISK OF BIAS: We used Cochrane's RoB 1 tool to assess risk of bias in the included study. SYNTHESIS METHODS: We were only able to perform a narrative review due to lack of data. We reported risk ratios (RR) with 95% CIs for dichotomous outcomes. We used GRADE to assess the certainty of evidence for each outcome. INCLUDED STUDIES: We found one eligible study, which compared electrostimulation of the gastrocnemius muscle and standard rehabilitation against standard rehabilitation in 50 dysvascular amputees. SYNTHESIS OF RESULTS: There was no new incidence of tissue loss reported. The following outcomes were not reported: time to new tissue loss; time to and incidence of minor amputation; HRQoL outcomes; adverse events; and hospital readmissions. Electrostimulation was associated with a three-fold reduction in the incidence of new major amputation of the CLL (RR 0.33, 95% CI 0.04 to 2.99), although time to new major amputation was not reported. There was no difference between groups in 12-month survival (RR 1.0, 95% CI 0.85 to 1.18). We judged the overall certainty of the evidence (GRADE) as very low across all outcomes, with unclear risk of selection and detection bias and high risk of performance bias. AUTHORS' CONCLUSIONS: Despite the care of the CLL being identified as a key research priority by two separate consensus papers, there is insufficient high-quality evidence to address this priority to date. We found only a single RCT suitable for inclusion, and this study was subject to risk of bias. Contralateral limb outcomes should be recorded in future research on dysvascular amputees. Until better evidence and clearer recommendations are available, this topic is likely to remain a research priority. FUNDING: This Cochrane review had no dedicated funding.

BACKGROUND: No in-shoe systems, measuring both components of plantar load (plantar pressure and shear stress) are available for use in patients with diabetes. The STAMPS (STrain Analysis and Mapping of the Plantar Surface) system utilises digital image correlation (DIC) to determine the strain sustained by a deformable insole, providing a more complete understanding of plantar shear load at the foot-surface interface. RESEARCH QUESTIONS: What is the normal range and pattern of strain at the foot-surface interface within a healthy population as measured by the STAMPS system? Is STAMPS a valid tool to measure the effects of plantar load? METHODS: A cross-sectional study of healthy participants was undertaken. Healthy adults without foot pathology or diabetes were included. Participants walked 20 steps with the STAMPS insole in a standardised shoe. Participants also walked 10â¯m with the Novel Pedar® plantar pressure measurement insole within the standardised shoe. Both measurements were repeated three times. Outcomes of interest were global and regional values for peak resultant strain (SMAG) and peak plantar pressure (PPP). RESULTS: In 18 participants, median peak SMAG and PPP were 35.01â¯% and 410.6kPa respectively. The regions of the hallux and heel sustained the highest SMAG (29.31â¯% (IQR 24.56-31.39) and 20.50â¯% (IQR 15.59-24.12) respectively) and PPP (344.8kPa (IQR 268.3 - 452.5) and 279.3kPa (IQR 231.3-302.1) respectively). SMAG was moderately correlated with PPP (r= 0.65, p < 0.001). Peak SMAG was located at the hallux in 55.6â¯% of participants, at the 1st metatarsal head (MTH) in 16.7â¯%, the heel in 16.7â¯%, toes 3-5 in 11.1â¯% and the MTH2 in 5.6â¯%. SIGNIFICANCE: The results demonstrate the STAMPS system is a valid tool to measure plantar strain. Further studies are required to investigate the effects of elevated strain and the relationship with diabetic foot ulcer formation.
RESUMO
Background: Diabetic foot osteomyelitis (DFO) is a major complication and can lead to significant morbidity and mortality. Systemic antibiotic therapy is often initiated first line to achieve quiescence of infection. To perform a multi-centre case review of systemic antibiotic intervention to treat adults with DFO in England and Wales and compare with national guidelines 'Diabetic foot problems: prevention and management'. Methods: Eight centres from England and Wales retrospectively collated data from a minimum of five adults (aged ≥ 18 years) from electronic case records. All patients were treated with systemic antibiotics following a new diagnosis of DFO (1 June 2021-31 December 2021). Results: 40 patients (35 males and 5 females) were included; the mean age was 62.3 years (standard deviation (SD) 13.0). Patients commenced systemic oral 14 (35%) or intravenous 26 (65%) antibiotic therapy following a new diagnosis of DFO. Twenty-seven (67.5%) patients were medically or surgically managed in the 12-week period with clinical quiescence of infection. Twenty-one patients (52.5%) had no recurrence of DFO infection within 12 weeks; seventeen (42.5%) of these patients had clinical quiescence of infection with systemic antibiotics alone without surgical intervention and nine (22.5%) of these cases had no recurrence of DFO. There were no cases of major amputation or death. All centres showed significant in-centre variability in systemic antibiotic management; variability was reported in the clinical and quantity indicators specifically to antibiotic selection, single versus dual therapy, mode of delivery and duration of treatment. Conclusions: This case review identifies there is existing variation when treating adults with systemic antibiotics for DFO. Further national guidance is required to standardise service delivery and care to improve patient outcomes.
RESUMO
Aims: The aim of this study was to produce clinical consensus recommendations about the non-surgical treatment of children with Perthes' disease. The recommendations are intended to support clinical practice in a condition for which there is no robust evidence to guide optimal care. Methods: A two-round, modified Delphi study was conducted online. An advisory group of children's orthopaedic specialists consisting of physiotherapists, surgeons, and clinical nurse specialists designed a survey. In the first round, participants also had the opportunity to suggest new statements. The survey included statements related to 'Exercises', 'Physical activity', 'Education/information sharing', 'Input from other services', and 'Monitoring assessments'. The survey was shared with clinicians who regularly treat children with Perthes' disease in the UK using clinically relevant specialist groups and social media. A predetermined threshold of ≥ 75% for consensus was used for recommendation, with a threshold of between 70% and 75% being considered as 'points to consider'. Results: A total of 40 participants took part in the first round, of whom 31 completed the second round. A total of 87 statements were generated by the advisory group and included in the first round, at the end of which 31 achieved consensus and were removed from the survey, and an additional four statements were generated. A total of 60 statements were included in the second round and 45 achieved the threshold for consensus from both rounds, with three achieving the threshold for 'points to consider'. The recommendations predominantly included self-management, particularly relating to advice about exercise and education for children with Perthes' disease and their families. Conclusion: Children's orthopaedic specialists have reached consensus on recommendations for non-surgical treatment in Perthes' disease. These statements will support decisions made in clinical practice and act as a foundation to support clinicians in the absence of robust evidence. The dissemination of these findings and the best way of delivering this care needs careful consideration, which we will continue to explore.

Objectives: Intervention in the pre-arthritis phase of RA could prevent or delay the onset of disease. The primary aim of this study was to explore perspectives of being at risk and potential preventive interventions among individuals at risk of developing RA and to identify factors influencing their engagement with prevention. A secondary aim, established during the analytical process, was to understand and compare different approaches to health-related behaviours related to prevention of RA. Methods: Anti-CCP-positive (CCP+) at-risk individuals with musculoskeletal symptoms but no synovitis participated in semi-structured interviews. Data were analysed using reflexive thematic analysis, followed by a secondary ideal-type analysis. Results: Nineteen CCP+ at-risk individuals (10 women; age range 35-70 years) participated. Three overarching themes were identified: being CCP+ at risk; aiming to prevent RA; and influencers of engagement. Participants described distress related to symptoms and uncertainty about disease progression. Many participants had concerns about medication side effects. In contrast, most participants expressed willingness to make lifestyle changes with the aim of preventing RA. Engagement with preventive measures was influenced by symptom severity, personal risk level, co-morbidities, experiences of taking other medications/supplements, knowledge of RA, risk factors and medications, and perceived effort. Three types of participants were identified from the data: proactive preventers, change considerers and fearful avoiders. Overall orientation to health behaviours also impacted the attitude towards preventing RA. Conclusion: Findings could inform recruitment and retention in RA prevention research and promote uptake of preventive interventions in clinical practice.
RESUMO
OBJECTIVE: To explore, from patients' perspectives, the symptoms and impact of Raynaud's phenomenon (RP) on the feet of patients with systemic sclerosis (SSc-RP), and to identify which foot-related domains are important to patients. METHODS: Forty participants (34 women) with SSc-RP took part in one of six focus groups held in the United Kingdom or United States. Participants were purposively sampled to ensure diversity in disease type, duration, and ethnicity. The topic guide included questions on RP impact, self-management, and treatment expectations. Qualitative content analysis was employed to identify key concepts in the data relating to foot-specific symptoms and their impact. Themes were organized by corresponding domains of potential importance. RESULTS: Twenty-eight participants (70 %) reported experiencing RP in their feet. Five themes were identified corresponding to domains of potential importance: temperature changes, pain, cramping and stiffness, numbness, and color changes. These issues negatively affected participants' lives, impairing walking, driving, and socializing, and causing issues with footwear and hosiery. CONCLUSIONS: This large qualitative study exploring the experiences of patients with SSc-RP in the feet identified several key domains of high importance to patients. SSc-RP is common in the feet, presents in several patterns, and impacts multiple aspects of patients' lives. These findings indicate where future foot-specific interventions for RP could be targeted. Findings from this study improve understanding of what domains are important to patients with SSc-RP affecting the feet and will contribute to the development of a core outcome set for foot and ankle disorders in rheumatic and musculoskeletal diseases.

BACKGROUND: Above cuff vocalisation (ACV) involves the application of an external flow of air via the subglottic port of a tracheostomy. ACV can facilitate vocalisation and may improve swallowing and quality of life for patients with a tracheostomy. A recent systematic review highlighted the limited evidence available for the acceptability, effectiveness, safety or optimal implementation of ACV. AIMS: To explore the experience of healthcare professionals (HCPs) using ACV and their perceptions of best practice. METHODS AND PROCEDURES: Semi-structured interviews were conducted with a range of HCPs with experience using ACV. Topics included: experiences with ACV, management of ACV, opinions about ACV, impact of COVID-19, future directions for ACV and impact on length of stay. Interviews were conducted online from December 2020 to March 2022. Data were analysed using reflexive thematic analysis. OUTCOMES AND RESULTS: Twenty-four HCPs were interviewed from seven countries and five professional groups. Four interconnected themes were developed: (1) moral distress amplifying the need to fix patients; (2) subjectivity and uncertainty leading to variations in practice and purpose; (3) knowledge and experience leading to control and caution; and (4) worth a try or a last resort. Theme four contained three sub-themes: (a) part of the toolbox; (b) useful but limited tool; and (c) following the patient's lead. The moral distress experienced by HCPs and their essential 'need to fix' patients seems to underpin the varied opinions of ACV. These opinions appear to be formed primarily on the basis of experience, because of the underlying subjectivities and uncertainties. As knowledge and experience with ACV increased, and adverse events were experienced, most HCPs became more cautious in their approach to ACV. CONCLUSIONS AND IMPLICATIONS: More research is needed to reduce the subjectivities and uncertainties surrounding ACV. The implementation of standardised procedures, processes, and competencies may help to reduce the frequency of adverse events and support a more controlled approach. Widening the focus of the purpose of ACV to include swallowing may help to maximise the potential benefits. WHAT THIS PAPER ADDS: What is already known on the subject There is limited and low-quality evidence for above cuff vocalisation (ACV) and clinical application and practice varies substantially. However, the reasons for this variation in practice and healthcare professionals' (HCPs') opinions of ACV were unclear. What this study adds HCPs' experiences and opinions of ACV vary as a result of the uncertainty and subjectivity surrounding ACV compounded by their personal experiences with it. A need for caution also appears to emerge as HCPs become more familiar and experienced with using ACV. What are the clinical implications of this work? Implementing standardised procedures, safety processes and competencies may help to compensate for the uncertainty and subjectivity surrounding ACV and may reduce the frequency of adverse events. Widening the focus of purpose of ACV, including swallowing in addition to communication, may increase the number of potential candidates and increase the potential benefits of ACV. Using multidisciplinary team (MDT) simulation training for ACV competency development might help to improve MDT working and ACV implementation.
RESUMO
Aims: Perthes' disease is an idiopathic avascular necrosis of the developing femoral head, often causing deformity that impairs physical function. Current treatments aim to optimize the joint reaction force across the hip by enhancing congruency between the acetabulum and femoral head. Despite a century of research, there is no consensus regarding the optimal treatment. The aim of this study was to describe the experiences of children, their families, and clinicians when considering the treatment of Perthes' disease. Methods: A qualitative study gathered information from children and their families affected by Perthes' disease, along with treating clinicians. Interviews followed a coding framework, with the interview schedule informed by behavioural theory and patient and public involvement. Transcripts were analyzed using the framework method. Results: A total of 24 interviews took place, with 12 child/family dyads and 12 clinicians from UK NHS centres. Interviews identified widespread variation of routine care. Children/their families recounted positive experiences when included in the decision-making process for treatment. There is a strong desire from clinicians and children/families for consistent guidance from everyone involved in care, which should be based on clinical consensus. Conclusion: This is the first study to describe how children/families and clinicians experienced receiving or providing treatment in Perthes' disease. The results indicate the need for robust evidence to support treatment decisions. Children and families valued feeling involved in the clinical decision-making process. Clinicians acknowledged the central importance of providing patient-centred care, particularly in the absence of robust evidence to guide the optimal treatment decisions. This study will inform a future Delphi project to develop clinical consensus guidelines for the treatment of Perthes' disease.
RESUMO
Introduction: Under plantar loading regimes, it is accepted that both pressure and shear strain biomechanically contribute to formation and deterioration of diabetic foot ulceration (DFU). Plantar foot strain characteristics in the at-risk diabetic foot are little researched due to lack of measurement devices. Plantar pressure comparatively, is widely quantified and used in the characterisation of diabetic foot ulceration risk, with a range of clinically implemented pressure measurement devices on the market. With the development of novel strain quantification methods in its infancy, feasibility testing and validation of these measurement devices for use is required. Initial studies centre on normal walking speed, reflecting common activities of daily living, but evaluating response to differing gait loading regimes is needed to support the use of such technologies for potential clinical translation. This study evaluates the effects of speed and inclination on stance time, strain location and strain response using a low-cost novel strain measurement insole. Methods: The STrain Analysis and Mapping of the Plantar Aspect (STAMPS) insole has been developed, and feasibility tested under self-selected normal walking speeds to characterise plantar foot strain, with testing beyond this limited regime required. A treadmill was implemented to standardise speed and inclination for a range of daily plantar loading conditions. A small cohort, comprising of five non-diabetic participants, were examined at slow (0.75 m/s), normal (1.25 m/s) and brisk (2 m/s) walking speeds and normal speed at inclination (10% gradient). Results: Plantar strain active regions were seen to increase with increasing speed across all participants. With inclination, it was seen that strain active regions reduce in the hindfoot and show a tendency to forefoot with discretionary changes to strain seen. Stance time decreases with increasing speed, as expected, with reduced stance time with inclination. Discussion: Comparison of the strain response and stance time should be considered when evaluating foot biomechanics in diabetic populations to assess strain time interval effects. This study supports the evaluation of the STAMPS insole to successfully track strain changes under differing plantar loading conditions and warrants further investigation of healthy and diabetic cohorts to assess the implications for use as a risk assessment tool for DFU.
RESUMO
Diabetic foot ulceration is driven by peripheral neuropathy, resulting in abnormal foot biomechanics and elevated plantar load. Plantar load comprises normal pressure and tangential shear stress. Currently, there are no in-shoe devices measuring both components of plantar load. The STAMPS (STrain Analysis and Mapping of the Plantar Surface) system was developed to address this and utilises digital image correlation (DIC) to determine the strain sustained by a plastically deformable insole, providing an assessment of plantar load at the foot-surface interface during gait. STAMPS was developed as a multi-layered insole, comprising a deformable mid-layer, onto which a stochastic speckle pattern film is applied. A custom-built imaging platform is used to obtain high resolution pre- and post-walking images. Images are imported into commercially available DIC software (GOM Correlate, 2020) to obtain pointwise strain data. The strain and displacement data are exported and post-processed with custom analysis routines (MATLAB, Mathworks Inc.), to obtain the resultant global and regional peak strain (SMAG), antero-posterior strain (SAP) and medio-lateral strain (SML). To validate the core technique an experimental test process used a Universal Mechanical Tester (UMT) system (UMT TriboLab, Bruker) to apply controlled vertical and tangential load regimes to the proposed multi-layer insole. A pilot study was then conducted to assess the efficacy of using the STAMPS system to measure in-shoe plantar strain in three healthy participants. Each participant walked 10 steps on the STAMPS insole using a standardised shoe. They also walked 10 m in the same shoe using a plantar pressure measurement insole (Novel Pedar®) to record peak plantar pressure (PPP) as a gold-standard comparator. The results of the experimental validation tests show that with increased normal force, at a constant shear distance, SMAG increased in a linear fashion. Furthermore, they showed that with increased shear distance, at a constant force, SMAG increased. The results of the pilot study found participant 1 demonstrated greatest SMAG in the region toes 3-5 (15.31%). The highest mean SMAG for participant 2 was at the hallux (29.31%). Participant 3 exhibited highest strain in the regions of the first and second metatarsal heads (58.85% and 41.62% respectively). Increased PPP was strongly associated with increased SMAG with a Spearman's correlation coefficient 0.673 (p < 0.0001). This study has demonstrated the efficacy of a novel method to assess plantar load across the plantar surface of the foot. Experimental testing validated the sensitivity of the method to both normal pressure and tangential shear stress. This technique was successfully incorporated into the STAMPS insole to reliably measure and quantify the cumulative degree of strain sustained by a plastically deformable insole during a period of gait, which can be used to infer plantar loading patterns. Future work will explore how these measures relate to different pathologies, such as regions at risk of diabetic foot ulceration.

OBJECTIVES: This study aimed to determine outcome domains of importance to patients living with foot and ankle disorders in rheumatic and musculoskeletal diseases (RMDs), by exploring the symptoms and impact of these disorders reported in existing qualitative studies. METHODS: Six databases were searched from inception to March 2022. Studies were included if they used qualitative interview or focus group methods, were published in English, and involved participants living with RMDs (inflammatory arthritis, osteoarthritis, crystal arthropathies, connective tissue diseases, and musculoskeletal conditions in the absence of systemic disease) who had experienced foot and ankle problems. Quality was assessed using the Critical Appraisal Skills Programme qualitative tool and confidence in the findings was assessed using the Grading of Recommendations Assessment, Development and Evaluation Confidence in the Evidence from Reviews of Qualitative research (GRADE-CERQual) approach. All data from the results section of included studies were extracted, coded and synthesised to develop themes. RESULTS: Of 1,443 records screened, 34 studies were included, with a total of 503 participants. Studies included participants with rheumatoid arthritis (n = 18), osteoarthritis (n = 5), gout (n = 3), psoriatic arthritis (n = 1), lupus (n = 1), posterior tibial tendon dysfunction (n = 1), plantar heel pain (n = 1), Achilles tendonitis (n = 1), and a mixed population (n = 3), who live with foot and ankle disorders. Seven descriptive themes were generated from the thematic synthesis: pain, change in appearance, activity limitations, social isolation, work disruption, financial burden and emotional impact. Descriptive themes were inductively analysed further to construct analytical themes relating to potential outcome domains of importance to patients. Foot or ankle pain was the predominant symptom experienced by patients across all RMDs explored in this review. Based on grading of the evidence, we had moderate confidence that most of the review findings represented the experiences of patients with foot and ankle disorders in RMDs. CONCLUSIONS: Findings indicate that foot and ankle disorders impact on multiple areas of patients' lives, and patients' experiences are similar regardless of the RMD. This study will inform the development of a core domain set for future foot and ankle research and are also useful for clinicians, helping to focus clinical appointments and measurement of outcomes within clinical practice.

OBJECTIVES: Foot and ankle involvement is common in rheumatic and musculoskeletal diseases, yet high-quality evidence assessing the effectiveness of treatments for these disorders is lacking. The Outcome Measures in Rheumatology (OMERACT) Foot and Ankle Working Group is developing a core outcome set for use in clinical trials and longitudinal observational studies in this area. METHODS: A scoping review was performed to identify outcome domains in the existing literature. Clinical trials and observational studies comparing pharmacological, conservative or surgical interventions involving adult participants with any foot or ankle disorder in the following rheumatic and musculoskeletal diseases (RMDs) were eligible for inclusion: rheumatoid arthritis (RA), osteoarthritis (OA), spondyloarthropathies, crystal arthropathies and connective tissue diseases. Outcome domains were categorised according to the OMERACT Filter 2.1. RESULTS: Outcome domains were extracted from 150 eligible studies. Most studies included participants with foot/ankle OA (63% of studies) or foot/ankle involvement in RA (29% of studies). Foot/ankle pain was the outcome domain most commonly measured (78% of studies), being the most frequently specified outcome domain across all RMDs. There was considerable heterogeneity in the other outcome domains measured, across core areas of manifestations (signs, symptoms, biomarkers), life impact, and societal/resource use. The group's progress to date, including findings from the scoping review, was presented and discussed during a virtual OMERACT Special Interest Group (SIG) in October 2022. During this meeting, feedback was sought amongst delegates regarding the scope of the core outcome set, and feedback was received on the next steps of the project, including focus group and Delphi methods. CONCLUSION: Findings from the scoping review and feedback from the SIG will contribute to the development of a core outcome set for foot and ankle disorders in RMDs. The next steps are to determine which outcome domains are important to patients, followed by a Delphi exercise with key stakeholders to prioritise outcome domains.

OBJECTIVES: Current evidence suggests that periodontal disease could be a causal risk factor for rheumatoid arthritis (RA) onset and progression. Earlier periodontal intervention in individuals at risk of RA could provide a unique opportunity to prevent or delay the onset of RA. This study aimed to explore the acceptability of periodontal treatment as a measure to potentially prevent RA among at-risk individuals and healthcare professionals. METHODS: Semistructured interviews were conducted with anti-CCP positive at-risk individuals (CCP+ at risk) and a range of healthcare professionals. At-risk participant data were analysed using reflexive thematic analysis; subsequent coding of healthcare professional data was deductive, based on a preidentified set of constructs. RESULTS: Nineteen CCP+ at-risk and 11 healthcare professionals participated. Three themes (six subthemes) were identified: (1) understanding risk (knowledge of shared at-risk factors; information and communication); (2) oral health perceptions and experiences (personal challenges and opportunities for dental intervention and oral health maintenance; external barriers) and (3) oral health treatment and maintenance (making oral health changes with the aim of preventing RA; acceptability of participation in periodontal research). CONCLUSIONS: Periodontal disease is common in individuals at risk of RA, but the impact of poor oral health may not be well understood. Oral health information should be tailored to the individual. CCP+ at-risk participants and healthcare professionals identified seeking dental treatment can be hindered by dental phobia, treatment costs or inability to access dentists. While CCP+ at-risk individuals may be reluctant to take preventive medications, a clinical trial involving preventive periodontal treatment is potentially acceptable.

BACKGROUND: Haemophilia is an X-linked recessive genetic disorder characterised by bleeding within soft tissue and joints. The ankle is disproportionally affected by haemarthropathy when compared to the elbows and knees; reported as the most affected joints in patients with haemophilia. Despite advances in treatment, patients still report ongoing pain and disability, however, the impact has not been evaluated, nor has the effect on health-related quality of life (HRQoL) or foot and ankle patient-reported outcome measures (PROMs). The primary aim of this study was to establish the impact of ankle haemarthropathy in patients with severe and moderate haemophilia A and B. Secondly to identify the clinical outcomes associated with a decline in HRQoL and foot and ankle PROMs. METHODS: A cross-sectional multi-centre questionnaire study was conducted across 18 haemophilia centres in England, Scotland and Wales with a recruitment target of 245 participants. The HAEMO-QoL-A and Manchester-Oxford Foot Questionnaire (MOXFQ) (foot and ankle) with total and domain scores measured impact on HRQOL and foot and ankle outcomes. Demographics, clinical characteristics, ankle haemophilia joint health scores, multi-joint haemarthropathy and Numerical Pain Rating Scales (NPRS) of "ankle pain over the past six months" were collected as a measure of chronic ankle pain. RESULTS: A total of 243 of 250 participants provided complete data. HAEMO-QoL-A and MOXFQ (foot and ankle) total and index scores indicated worse HRQoL with total scores ranging from a mean of 35.3 to 35.8 (100 best-health) and 50.5 to 45.8 (0 best-health) respectively. NPRS (mean (SD)) ranged from 5.0 (2.6) to 5.5 (2.5), with median (IQR) ankle haemophilia joint health score of 4.5 (1 to 12.5) to 6.0 (3.0 to 10.0) indicating moderate to severe levels of ankle haemarthropathy. Ankle NPRS over six months and inhibitor status were associated with decline in outcome. CONCLUSIONS: HRQoL and foot and ankle PROMs were poor in participants with moderate to severe levels of ankle haemarthropathy. Pain was a major driver for decline in HRQoL and foot and ankle PROMs and use of NPRS has the potential to predict worsening HRQoL and PROMs at the ankle and other affected joints.

BACKGROUND: Foot and ankle involvement is common in rheumatic and musculoskeletal diseases (RMDs). High-quality evidence is lacking to determine the effectiveness of treatments for these disorders. Heterogeneity in the outcomes used across clinical trials and observational studies hinders the ability to compare findings, and some outcomes are not always meaningful to patients and end-users. The Core set of Outcome Measures for FOot and ankle disorders in RheumaTic and musculoskeletal diseases (COMFORT) study aims to develop a core outcome set (COS) for use in all trials of interventions for foot and ankle disorders in RMDs. This protocol addresses core outcome domains (what to measure) only. Future work will focus on core outcome measurement instruments (how to measure). METHODS: COMFORT: Core Domain Set is a mixed-methods study involving the following: (i) identification of important outcome domains through literature reviews, qualitative interviews and focus groups with patients and (ii) prioritisation of domains through an online, modified Delphi consensus study and subsequent consensus meeting with representation from all stakeholder groups. Findings will be disseminated widely to enhance uptake. CONCLUSIONS: This protocol details the development process and methodology to identify and prioritise domains for a COS in the novel area of foot and ankle disorders in RMDs. Future use of this standardised set of outcome domains, developed with all key stakeholders, will help address issues with outcome variability. This will facilitate comparing and combining study findings, thus improving the evidence base for treatments of these conditions. Future work will identify suitable outcome measurement instruments for each of the core domains.

INTRODUCTION: Moderate haemophilia has traditionally been associated with less complications than severe haemophilia. Changes in treatment recommendations have highlighted the burden of moderate haemophilia with a subset of patients with a severe bleeding phenotype. The ankle joint is disproportionally affected by ankle haemarthropathy however the impact has not been evaluated in moderate haemophilia, nor the effect on health related quality of life (HRQoL) or foot and ankle outcomes. AIMS: To establish the impact of ankle haemarthropathy in patients with moderate haemophilia. METHODS: A multicentre questionnaire study recruited patients from 11 haemophilia centres in England, Scotland and Wales. The HAEMO-QoL-A and Manchester-Oxford foot and ankle questionnaire (MOXFQ) with total and domain scores measured impact. Measures of pain and ankle haemophilia joint health (HJHS) scores were also collected. RESULTS: Twenty-nine participants were recruited. HAEMO-QoL A mean (SD) total scores of 10.8 (5.2) of 100 (best health) and foot and ankle specific MOXFQ total scores of 45.5 (24.7) above zero (best outcome) indicate poor HRQoL and foot and ankle outcomes. Average ankle pain over past 6 months of (0-10) 5.5 (SD2.5) was reported and median (IQR) ankle HJHS of 3.0 (1;12.5) to 4.5 (0;9.5) for the left and right ankles. CONCLUSION: HRQoL and foot and ankle specific outcomes are poor in patients with moderate haemophilia and ankle haemarthropathy, driven by chronic levels of ankle joint pain. Despite moderate haemophilia being considered less affected by haemarthrosis and haemarthropathy, patients with a bleeding or haemarthropathy phenotype are clinically similar to patients with severe haemophilia A.

BACKGROUND: End-stage ankle osteoarthritis typically causes severe pain and impaired function. Surgical treatment involves total ankle replacement (TAR) or ankle fusion. Definitive evidence about which procedure is optimal is lacking. No previous studies have thoroughly explored patients' experiences across the entire TAR/ankle fusion pathway. This study aimed to address this gap by exploring perceptions of surgery, education, rehabilitation and outcomes among patients who had undergone TAR or ankle fusion. METHODS: Seven participants were purposively selected from an orthopaedic centre in northern England (3 females, 4 males). Participants had undergone primary TAR without revision (n = 2), TAR requiring revision (n = 3) or ankle fusion (n = 2). Each participant completed a single semi-structured interview. Interviews were digitally recorded, transcribed verbatim and analysed thematically. RESULTS: Three themes, each with two subthemes, were identified: decision-making (seeking help; surgical options), perceptions of support (information/education; clinical support) and impact on the individual (personal circumstances and beliefs; post-operative outcomes). Pain affecting participants' valued activities was key to their decision to seek help. Participants' decision between TAR and ankle fusion was influenced by multiple factors. Concerns regarding the lack of joint flexibility following fusion were highlighted, with some participants perceiving TAR as a "proper ankle" that would enable them to avoid limping. Participants obtained information from various sources, with most feeling that the education from their care team was inadequate. Participants' individual circumstances and beliefs influenced their decision-making and perceptions of their post-operative outcomes. Finally, whilst most participants were pleased with their outcomes, some experienced substantial ongoing problems such as difficulty walking and chronic pain. CONCLUSIONS: This study demonstrates the importance of providing adequate education about TAR and ankle fusion to enable patients to make informed decisions. Most participants felt that the education and clinical support they received did not fully meet their needs. Participants' personal circumstances and beliefs had a strong influence on their decision-making and perceptions of their post-operative outcomes, highlighting the need to personally tailor education and clinical support. Future work with a larger sample of patients and other key stakeholders is required to develop consensus-based guidelines on pre- and post-operative support for patients undergoing TAR/ankle fusion.

The increase in the global diabetic population is leading to an increase in associated complications such as diabetic foot ulceration (DFU), associated amputations, morbidity, which substantial treatment costs. Early identification of DFU risk is therefore of great benefit. International guidelines recommend off-loading is the most important intervention for healing and prevention of DFU, with current research focused on pressure measurement techniques. The contribution of strain to DFU formation is not well understood due to challenges in measurement. The limited data available in the literature suggest that plantar strain is involved in ulcer formation. As a consequence, there is a need for plantar strain measurement systems to advance understanding and inform clinical treatment. A method was developed to determine plantar strain based on a Digital Image Correlation (DIC) approach. A speckle pattern is applied to the plantar aspect of the foot using a low ink transference method. A raised walkway with transparent panels is combined with a calibrated camera to capture images of the plantar aspect throughout a single stance phase. Plantar strain is then determined using 2D DIC and custom analysis summarises these data into clinically relevant metrics. A feasibility study involving six healthy participants was used to assess the efficacy of this new technique. The feasibility study successfully captured plantar surface strain characteristics continuously throughout the stance phase for all participants. Peak mean and averaged mean strains varied in location between participants when mapped into anatomical regions of plantar interest, ranging from the calcaneus to the metatarsal heads and hallux. This method provides the ability to measure plantar skin strain for use in both research and clinical environments. It has the potential to inform improved understanding of the role of strain in DFU formation. Further studies using this technique can support these ambitions and help differentiate between healthy and abnormal plantar strain regimes.

OBJECTIVES: Evidence on the current status of gender equity in academic rheumatology in Europe and potential for its improvement is limited. The EULAR convened a task force to obtain empirical evidence on the potential unmet need for support of female rheumatologists, health professionals and non-clinical scientists in academic rheumatology. METHODS: This cross-sectional study comprised three web-based surveys conducted in 2020 among: (1) EULAR scientific member society leaders, (2) EULAR and Emerging EULAR Network (EMEUNET) members and (3) EULAR Council members. Statistics were descriptive with significance testing for male/female responses assessed by χ2 test and t-test. RESULTS: Data from EULAR scientific member societies in 13 countries indicated that there were disproportionately fewer women in academic rheumatology than in clinical rheumatology, and they tended to be under-represented in senior academic roles. From 324 responses of EULAR and EMEUNET members (24 countries), we detected no gender differences in leadership aspirations, self-efficacy in career advancement and work-life integration as well as the share of time spent on research, but there were gender differences in working hours and the levels of perceived gender discrimination and sexual harassment. There were gender differences in the ranking of 7 of 26 factors impacting career advancement and of 8 of 24 potential interventions to aid career advancement. CONCLUSIONS: There are gender differences in career advancement in academic rheumatology. The study informs a EULAR task force developing a framework of potential interventions to accelerate gender-equitable career advancement in academic rheumatology.
