Item Foot and ankle pathologies in juvenile idiopathic arthritis: A narrative review(SpringerNature, 2017-09-01) Fellas, Antoni; Hawke, Fiona; Santos, Derek; Coda, AndreaIntroduction: Foot and ankle pathologies are common in juvenile idiopathic arthritis (JIA) and can cause physical disability and reduce quality of life (1). Early detection and evidence-based treatment of these symptomatic pathologies are an important first step in preventing ongoing pain and long-term disabilities in children with JIA.Item Contribution of vision, touch, and hearing to the use of sham devices in acupuncture-related studies(Elsevier, 2019-12-23) Tan, Chee-Wee; Santos, DerekThis study investigates whether visual deprivation influences participants' accuracy in differentiating between real and sham acupuncture needles. It also evaluates the relative contributions of tactile, visual, and auditory cues that participants use in their decision-making processes. In addition, a simple sensory decision-making model for research using acupuncture sham devices as comparative controls is proposed. Forty healthy individuals underwent two conditions (blindfolded and sighted) in random sequence. Four sham and four real needles were randomly applied to the participants' lower limb acupoints (ST32 to ST39). Participants responded which needle type was applied. Participants then verbally answered a questionnaire on which sensory cues influenced their decision-making. The proportion of correct judgments, P(C), was calculated to indicate the participants' accuracy in distinguishing between the needle types. Visual deprivation did not significantly influence the participants' discrimination accuracy. Tactile cues were the dominant sensory modality used in decision-making, followed by visual and auditory cues. Sharp and blunt sensations were associated with the real and sham needles, respectively, for both conditions. This study confirmed that tactile cues were the main sensory modalities used in participant decision-making during acupuncture administration. Also, short-term blindfolding of participants during procedures will unlikely influence blinding effectiveness.Item It’s time we talked about Charcot foot: Results of a podiatry patient education questionnaire(Wounds Group, 2019-09-01) Bullen, Benjamin; Young, Matthew; McArdle, Carla; Ellis, Mairghread JHIn contrast with diabetic foot ulceration (DFU) and lower-extremity amputation (LEA), current Scottish patient information leaflets reserve Charcot foot education for individuals ‘In Remission’ from, or with active, Charcot foot. A small group of Scottish NHS podiatrists recently agreed Charcot foot education should be delivered to all ‘At-risk’ individuals with diabetic peripheral neuropathy. This study sought to compare discussion about diabetes foot disease and Charcot foot between ‘At-risk’ and ‘In Remission’ groups among this cohort. Fourteen participants completed an ‘At-risk’ component of the Charcot foot patient education questionnaire, while six also completed an ‘In Remission’ component. Topics investigated for both groups included DFU and LEA risk, footwear and insoles, and signs of infection and Charcot foot. Frequency of discussion data was captured with a five-point Likert scale. Median response and interquartile range (IQR) were described and compared between groups. Median values and IQR for discussion of DFU and LEA risk were 5 (IQR 1) and 3 (IQR 1.25) respectively for ‘At-risk’ groups, and 5 (IQR 0.25) and 3 (IQR 2), respectively, among the ‘In Remission’ group. For discussion of footwear and insoles, the median response was 4 (IQR 1) for ‘At-risk’ and 5 (IQR 1) for ‘In Remission’ groups, reversed for discussion of signs of infection. The greatest between-group discrepancy was found for discussion of Charcot foot, with median responses and IQR found to be 3 (IQR 2) and 5 (IQR 0.25) for ‘At-risk’ and ‘In Remission’ groups, respectively. This discrepancy has potential implications for Charcot foot educational strategies, audit and research. It is proposed that ‘always’ should be the benchmark for frequency of Charcot foot education, not just for those ‘In Remission’ but also those ‘At risk’.Item The effect of EVA and TPU custom foot orthoses on running economy, running mechanics, and comfort(Frontiers Media, 2019-09-19) Van Alsenoy, Ken K.; Ryu, Joong Hyun; Girard, Olivier; Hamlin, Michael JohnCustom made foot orthoses (CFO) with specific material properties have the potential to alter ground reaction forces but their effect on running mechanics and comfort remains to be investigated. We determined if CFO manufactured from ethyl-vinyl acetate (EVA) and expanded thermoplastic polyurethane (TPU) materials, both compared to standardized footwear (CON), improve running economy (RE), running mechanics, and comfort at two running speeds. Eighteen well-trained, male athletes ran on an instrumented treadmill for 6min at high (HS) and low (LS) speeds corresponding to and 15% lower than their first ventilatory threshold (13.8 ± 1.1 and 11.7 ± 0.9 km.h−1, respectively) in three footwear conditions (CON, EVA, and TPU). RE, running mechanics and comfort were determined. Albeit not reaching statistical significance (P = 0.11, ! 2 = 0.12), RE on average improved in EVA (+2.1 ± 4.8 and +2.9 ± 4.9%) and TPU (+0.9 ± 5.9 and +0.9 ± 5.3%) compared to CON at LS and HS, respectively. Braking force was decreased by 3.4±9.1%at LS and by 2.7 ± 9.8% at HS for EVA compared to CON (P = 0.03, ! 2 = 0.20). TPU increased propulsive loading rate by 20.2 ± 24 and 16.4 ± 23.1% for LS and HS, respectively compared to CON (P = 0.01, ! 2 = 0.25). Both arch height (P = 0.06, ! 2 = 0.19) and medio-lateral control (P = 0.06, ! 2 = 0.16) showed a trend toward improved comfort for EVA and TPU vs. CON. Compared to shoes only, mainly EVA tended to improve RE and comfort at submaximal running speeds. Specific CFO-related running mechanical adjustments included a reduced braking impulse occurring in the first 25% of contact time with EVA, whereas wearing TPU increased propulsive loading rate.Item Overcoming barriers to self-management: The person-centred diabetes foot behavioural agreement(Elsevier, 2019-01-11) Bullen, Benjamin; Young, Matthew; McArdle, Carla; Ellis, Mairghread JHObjective - Behavioural agreements have been proposed as a clinical strategy for improving concordance with diabetes foot self-management practices, both for individuals ‘At-risk’ of, and with active, diabetes foot disease. This narrative review sought to explore the potential supportive role of person-centred diabetes foot behavioural agreements in promoting protective foot self-management behaviours among ‘At-risk’ individuals. Conclusions - Health care professionals (HCPs) involved in diabetes foot risk stratification and management dedicate considerable time, effort and resources to the prevention of diabetic foot ulcers (DFU) and lower extremity amputation (LEA) and are uniquely placed to deliver person-centred diabetes self-management education and support (DSMES) interventions. Written, verbal and non-verbal agreements are consistent with a wider global move toward DSMES approaches, respectful of people’s preferences, and supporting them to undertake protective self-care behaviours. Practice implications - It is theorised that clear communication of the roles of the person with diabetes, their family or carers and HCPs may improve concordance with self-management behaviours. Rather than a punitive measure or means of facilitating discharge of ‘non-concordant’ individuals, person-centred behavioural agreements should be framed positively, as a means of delineating, prescribing and supporting individual diabetes foot-care responsibilities. This is an area worthy of further research.Item Predictive parameters of arteriovenous fistula maturation in patients with end-stage renal disease(Korean Society of Nephrology, 2018-09-30) Siddiqui, Muhammad A.; Ashraff, Suhel; Santos, Derek; Rush, Robert; Carline, Tom; Raza, ZahidBackground:The objevctive of the present study was to explore the potential influence of blood markers and patient factors such as risk factors, kidney function profile, coagulation profile, lipid profile, body mass index, blood pressure, and vein diameter on the maturation of arteriovenous fistula (AVF) in patients with end-stage renal disease. Methods:Retrospective data from 300 patients who had undergone AVF creation at the Royal Infirmary of Edinburgh were examined. A predictive logistic regression model was developed using a backward stepwise procedure. Model performance, discrimination, and calibration were assessed using the receiver operating characteristic (ROC) curve and Hosmer-Lemeshow goodness-of-fit test. The final model was externally validated by 100 prospective patients who received a new fistula at the Royal Infirmary of Edinburgh. Results:A total of 400 (300 retrospective and 100 prospective) patients were recruited for this study, with a mean age of 60.14 ± 15.9 years (development set) and 58 ± 15 years (validation set), respectively (P = 0.208). Study results showed that males were twice as likely to undergo fistula maturation as females, while patients with no evidence of peripheral vascular disease (PVD) were three times more likely to mature their fistula and a preoperative vein diameter > 2.5 mm resulted in a fivefold increase in fistula maturation as compared with a vein size of less than 2.5 mm. The model for fistula maturation had fair discrimination, as indicated by the area under the ROC curve (0.68), but good calibration as indicated by the Hosmer-Lemeshow test (P = 0.79). The area under the receiver operating curve for the validation model in the validation set was 0.59. Similarly, in the validation set, the Hosmer-Lemeshow statistic indicated an agreement between the observed and predicted probabilities of maturation (P > 0.05). Conclusion:Gender, PVD, and vein size are independent predictors of AVF maturation. The clinical utility of these risk categories in the maturation of AVF requires further evaluation in longer follow-up.Item Charcot neuroarthropathy patient education among podiatrists in Scotland: a modified Delphi approach.(BioMed Central, 2018-09-24) Bullen, Benjamin; Young, Matthew; McArdle, Carla; Ellis, Mairghread JHBackground This evaluation sought to determine current Charcot neuroarthropathy (CN) diabetes patient education practices among Scottish National Health Service (NHS) and academic podiatrists and evaluate novel visual tools and develop expert consensus for future practice. Methods Questionnaires collected mixed qualitative and quantitative responses, analysed concurrently within a convergence coding matrix. Delphi methodology permitted member-checking and agreement of consensus over two rounds. Results Fourteen participants (16.28%) completed a Round One questionnaire, leading to the generation of four themes; Experience; Person-Centred Care and the Content and Context of CN patient education. Seven consensus statements were subsequently developed and six achieved over 80% agreement among 16 participants (18.60%) with a Round Two questionnaire. Respondents agreed CN patient education should be considered for all ‘At-risk’ individuals with diabetic peripheral neuropathy (DPN). Verbal metaphors, including the ‘rocker-bottom’ foot, soft or brittle bones, collapsing, walking on honeycomb and a shattering lightbulb were frequently employed. Visual tools, including visual metaphors and The Charcot Foot Thermometer, were positively evaluated and made available online. Conclusions Key findings included respondent’s belief that CN education should be considered for all individuals with DPN and the frequent use of simile, analogy and metaphor in CN education. The concept of ‘remission’ proved controversial due to its potential for misinterpretation.Item Complications of Stump Healing Among Diabetic Population(Society of Endocrinology and Metabolism of Turkey, 2018-06-19) Ashraff, Suhel; Siddiqui, Muhammad A.; Santos, Derek; Carline, TomLower limb amputation is a major procedure performed in diabetic patients with multiple comorbidities. Almost 10% of the National Health Service budget is taken up by diabetes, with diabetes-related complications accounting for 80% of the costs. The process of wound healing is complex and involves regenerating the cellular organization and the tissue layers. Diabetics are five times more predisposed to wound infection than patients without diabetes mellitus. The amputated stump frequently becomes infected due to inadequate blood circulation, a weak immune system, and poorly controlled diabetes mellitus. Pain, stump edema, and osteomyelitis are significant complications associated with lower limb amputation wounds. A number of factors may substantiate the need for re-amputation, such as stump pain and/or phantom limb pain, delayed stump infection, the formation of symptomatic bone spurs, assessment of the skin flap designed to preserve stump length, and preparation of the stump for the prosthetic device. There are currently no reliable standards that can be referred to prior to leg amputation. The clinicians, therefore, have to rely on their judgment and investigatory parameters. The main purpose of this review is to discuss the difficulties of stump healing in the diabetic population.Item Physical Examination Tools Used to Identify Swollen and Tender Lower Limb Joints in Juvenile Idiopathic Arthritis: A Scoping Review(Hindawi Publishing Corporation, 2018-05-15) Fellas, Antoni; Singh-Grewal, Davinder; Santos, Derek; Coda, AndreaBackground. Juvenile idiopathic arthritis (JIA) is the most common form of rheumatic disease in childhood and adolescents, affecting between 16 and 150 per 100,000 young persons below the age of 16. The lower limb is commonly affected in JIA, with joint swelling and tenderness often observed as a result of active synovitis. Objective. The objective of this scoping review is to identify the existence of physical examination (PE) tools to identify and record swollen and tender lower limb joints in children with JIA. Methods. Two reviewers individually screened the eligibility of titles and abstracts retrieved from the following online databases: MEDLINE, EMBASE, Cochrane Central Register of Controlled Trials, and CINAHL. Studies that proposed and validated a comprehensive lower limb PE tool were included in this scoping review. Results. After removal of duplicates, 1232 citations were retrieved, in which twelve were identified as potentially eligible. No studies met the set criteria for inclusion. Conclusion. Further research is needed in developing and validating specific PE tools for clinicians such as podiatrists and other allied health professionals involved in the management of pathological lower limb joints in children diagnosed with JIA. These lower limb PE tools may be useful in conjunction with existing disease activity scores to optimise screening of the lower extremity and monitoring the efficacy of targeted interventions.Item Here we go again: remission and re-ulceration in the diabetic foot(SB Communications, 2018-04-25) Bullen, Benjamin; Young, Matthew; McArdle, Carla; Ellis, Mairghread JHA case report of an individual presenting with a self-inflicted diabetes foot ulcer following inappropriate over-the-counter corn plaster use was published in the October 2016 issue of this journal (Bullen and Young, 2016). The role of low health literacy was discussed in order to optimise diabetes foot education. This update documents recurrent ulceration 1 year following initial presentation, illustrating a need for ongoing, personalised diabetes foot education for those ‘in remission’ from foot disease. The importance of patient recognition of the signs and symptoms of benign hyperkeratotic lesions and active diabetes foot disease is discussed, facilitating early presentation to podiatry services and prevention of further complications.
