Diabetic foot disease carries an intrinsic high risk of mortality and other severe outcomes in type 2 diabetes: a propensity score-matched retrospective population-based study.

BACKGROUND: To evaluate the association between diabetic foot disease (DFD) and the incidence of fatal and non-fatal events in individuals with type 2 diabetes (T2DM) from primary-care settings. METHODS: We built a cohort of people with a first DFD episode during 2010-2015, followed up until 2018. These subjects were 1 to 1 propensity score matched to subjects with T2DM without DFD. The incidence of all-cause mortality, the occurrence of new DFD, amputations, cardiovascular diseases, or composite outcome, including all-cause mortality and/or cardiovascular events during the follow-up period, were calculated. A Cox proportional hazard analysis was conducted to evaluate the hazard ratios (HR) for different events. RESULTS: Overall, 11,117 subjects with T2DM with a first episode of DFD were compared with subjects without DFD. We observed higher incidence rates (IRs) for composite outcome (33.9 vs. 14.5 IR per 100 person-years) and a new DFD episode event (22.2 vs. 1.1 IR per 100 person-years) in the DFD group. Compared to those without DFD, those with a first episode of DFD had a higher HR for all events, with excess rates particularly for amputation and new DFD occurrence (HR: 19.4, 95% CI: 16.7-22.6, HR: 15.1, 95% CI: 13.8-16.5, respectively) was found. CONCLUSIONS: Although DFD often coexists with other risk factors, it carries an intrinsic high risk of morbidity and mortality in individuals with T2DM. DFD should be regarded as a severe complication already at its onset, as it carries a poor clinical prognosis.

Definitions and criteria for diabetes-related foot disease (IWGDF 2023 update).

Multiple disciplines are involved in the management of diabetes-related foot disease and a common vocabulary is essential for clear communication. Based on the systematic reviews of the literature that form the basis of the International Working Group on the Diabetic Foot (IWGDF) Guidelines, the IWGDF has developed a set of definitions and criteria for diabetes-related foot disease. This document describes the 2023 update of these definitions and criteria. We suggest these definitions be used consistently in both clinical practice and research, to facilitate clear communication with people with diabetes-related foot disease and between professionals around the world.

Standards for the development and methodology of the 2023 IWGDF guidelines.

AIMS: Diabetes-related foot disease is a major source of patient burden and societal costs. Investing in evidence-based international guidelines on diabetes-related foot disease is important to reduce this burden and costs, provided the guidelines are focused on outcomes important to key stakeholders and are evidence-based and properly implemented. MATERIALS AND METHODS: The International Working Group on the Diabetic Foot (IWGDF) has published and updated international guidelines since 1999. The 2023 updates were made using the Grading of Recommendations Assessment Development and Evaluation evidence-to-decision framework. This concerns formulating relevant clinical questions and important outcomes, conducting systematic reviews of the literature and meta-analyses where appropriate, completing summary of judgement tables, and writing recommendations that are specific, unambiguous and actionable, along with their transparent rationale. RESULTS: We herein describe the development of the 2023 IWGDF Guidelines on the prevention and management of diabetes-related foot disease, which consists of seven chapters, each prepared by a separate working group of international experts. These chapters provide guidelines related to diabetes-related foot disease on prevention; classification of diabetes-related foot ulcer, offloading, peripheral artery disease, infection, wound healing interventions, and active Charcot neuro-osteoarthropathy. Based on these seven guidelines, the IWGDF Editorial Board also produced a set of practical guidelines. Each guideline underwent extensive review by the members of the IWGDF Editorial Board as well as independent international experts in each field. CONCLUSIONS: We believe that the adoption and implementation of the 2023 IWGDF guidelines by healthcare providers, public health agencies, and policymakers will improve the prevention and management of diabetes-related foot disease, and subsequently reduce the worldwide patient and societal burden caused by this disease.

Assessment and management of diabetes-related foot infection according to the new International Working Group on the Diabetic Foot guidelines 2023-Multidisciplinary grand rounds.

Diabetes-related foot disease is a serious and common complication for people with diabetes mellitus. The gold standard care for a person with diabetes-related foot disease is the involvement of a multidisciplinary foot team engaged in evidence-based care. To date, there are seven International Working Group on the Diabetic Foot (IWGDF) guidelines published to assist healthcare providers in managing diabetes-related foot disease around the world. This review discusses the acute management of diabetes-related foot infection with insights from experts of various specialities (internal medicine, infectious disease, vascular surgery, radiology) with a discussion on the implementation of IWGDF guidelines in real life practice and the challenges that healthcare providers may face.

Recent developments in targets for ischemic foot disease.

Diabetes is a key risk factor for ischaemic foot disease, which causes pain, tissue loss, hospital admission, and major amputation. Currently, treatment focuses on revascularisation, but many patients are unsuitable for surgery and revascularisation is frequently unsuccessful. The authors describe recent research in animal models and clinical trials investigating novel medical targets for ischaemia, including theories about impaired wound healing, animal models for limb ischaemia and recent randomised controlled trials testing novel medical therapies. Novel targets identified in animal models included stimulating mobilisation of CD34+ progenitor cells through upregulating oncostatin M or microRNA-181, downregulating tumour necrosis factor superfamily member 14, or activating the Wingless pathway. Within the ischaemic limb vasculature, upregulation of apolipoprotein L domain containing 1, microRNA-130b or long noncoding RNA that enhances endothelial nitric oxide synthase expression promoted limb blood supply recovery, angiogenesis, and arteriogenesis. Similarly, administration of soluble guanylate cyclase stimulators riociguat or praliciguat or 3-ketoacyl-CoA thiolase inhibitor trimetazidine promoted blood flow recovery. Translating pre-clinical findings to patients has been challenging, mainly due to limitations in clinically translatable animal models of human disease. Promising results have been reported for administering plasmids encoding hepatocyte growth factor or intra-arterial injection of bone marrow derived cells in small clinical trials. It remains to be seen whether these high resource therapies can be developed to be widely applicable. In conclusion, an ever-expanding list of potential targets for medical revascularisation is being identified. It is hoped that through ongoing research and further larger clinical trials, these will translate into new broadly applicable therapies to improve outcomes.

'Werner Syndrome foot'-A case series of four Irish Traveller siblings with Werner Syndrome, diabetes mellitus and complex foot disease.

AIMSWERNER SYNDROME IS A RARE PREMATURE AGEING AUTOSOMAL RECESSIVE DISORDER CAUSED BY PATHOGENIC VARIANTS IN THE WRN GENE. PEOPLE WITH WERNER SYNDROME MAY DEVELOP DIABETES MELLITUS. CHRONIC FOOT ULCERATION IS SEEN, WITH SOME CHARACTERISTICS OVERLAPPING WITH DIABETIC FOOT DISEASE. HOWEVER, THE CLINICAL COURSE OF THE ULCERATION IS ATYPICAL OF DIABETIC FOOT DISEASE. WE PRESENT FOUR SIBLINGS FROM AN IRISH TRAVELLER FAMILY WITH WERNER SYNDROME TO HIGHLIGHT THE COMPLEXITY OF THIS CONDITION. THE IRISH TRAVELLER POPULATION ARE AN INDIGENOUS, ENDOGAMOUS POPULATION IN WHICH CONSANGUINITY IS COMMON. AS A RESULT, RARE AUTOSOMAL RECESSIVE DISORDERS ARE PREVALENT AMONG THIS POPULATION: . METHODS: We describe our experience managing the complex foot disease seen in all four siblings. Foot complications present in the siblings include painful peripheral neuropathy, chronic foor ulceration, underlying osteomyelitis and acral melanoma. RESULTS: The cases are described individually, with a particular focus on the complex foot disease associated with the condition. CONCLUSIONS: Although the siblings attend a diabetic foot clinic, we suggest that the combination of clinical features seen in these cases is unique to Werner syndrome and warrants the title 'Werner Syndrome' (rather than 'Diabetic') foot.

Quantitative interpretation of infrared images of lower limbs in individuals with and without type 2 diabetes mellitus.

BACKGROUND: The quantitative interpretation of the radiometric information extracted from infrared (IR) images in individuals with and without type 2 diabetes mellitus (DM2) is an open problem yet to be solved. This is of particular value given that DM2 is a worldwide health problem and onset for evolution toward diabetic foot disease (DFD). Since DM2 causes changes at the vascular and neurological levels, the metabolic heat distribution on the outer skin is modified as a consequence of such alterations. Of particular interest in this contribution are those alterations displayed over the skin's heat patterns at the lower limbs. At the core of such alterations is the deterioration of the vascular and neurological networks responsible for procuring systemic thermoregulation. It is within this context that IR imaging is introduced as a likely aiding tool to assist with the clinical diagnosis of DM2 at stages early enough to prevent the evolution of the DFD. METHODS: IR images of lower limbs are acquired from a cohort of individuals clinically diagnosed with and without DM2. Additional inclusion criteria for patients are to be free from any visible wound or tissue-related trauma (e.g., injuries, edema, and so forth), and also free from non-metabolic comorbidities. All images and data are equally processed and analyzed using indices that evaluate the spatial and temporal evolution of temperature distribution in lower limbs. We studied the temporal response of individuals' legs after inducing an external stimulus. For this purpose, we combine the information of the asymmetry and thermal response index (ATR) and the thermal response index (TRI), computed using images at different times, improving the results previously obtained individually with ATR and TRI. RESULTS: A novel representation of the information extracted from IR images of the lower limbs in individuals with and without DM2 is presented. This representation was built using the ATR and TRI indices for the anterior and posterior views (PVs), individually and combining the information from both views. In all cases, the information of each index and each view presents linearity properties that allow said information to be interpreted quantitatively in a well-defined and limited space. This representation, built in a polar coordinate space, allows obtaining sensitivity values of 86%, 97%, and 97%, and specificity values of 83%, 72%, and 78% for the anterior view (AV), the PV, and the combined views, respectively. Additionally, it was observed that the angular variable that defines this new representation space allows to significantly (p < 0.01) differentiate the groups, while correlating with clinical variables of interest, such as glucose and glycated hemoglobin. CONCLUSION: The linearity properties that exist between the ATR and TRI indices allow a quantitative interpretation of the information extracted from IR images of the lower extremities of individuals with and without DM2, and allow the construction of a representation space that eliminates possible ambiguities in the interpretation, while simplifying it, making it accessible for clinical use.

Gap analysis of diabetes-related foot disease management systems in Pacific Islands Countries and Territories.

BACKGROUND: Pacific Island Countries and Territories (PICTs) are known to have high prevalence of Diabetes Mellitus and high incidence of diabetes-related foot disease. Diabetes-related foot disease can lead to lower limb amputation and is associated with poor outcomes, with increased morbidity and mortality. The purpose of this study was to gain a better understanding of diabetes-related foot disease management in selected countries in PICTs and to identify potential barriers in management of diabetes-related foot disease management in the region. METHODS: A cross-sectional survey was sent to eleven hospitals across six selected PICTs. The survey instrument was designed to provide an overview of diabetes-related foot disease (number of admissions, and number of lower limb amputations over 12 months) and to identify clinical services available within each institution. Two open-ended questions (free text responses) were included in the instrument to explore initiatives that have helped to improve management and treatment of diabetes-related foot diseases, as well as obstacles that clinicians have encountered in management of diabetes-related foot disease. The survey was conducted over 6 weeks. RESULTS: Seven hospitals across four countries provided responses. Number of admissions and amputations related to diabetes-related foot disease were only reported as an estimate by clinicians. Diabetes-related foot disease was managed primarily by general medicine physician, general surgeon and/or orthopaedic surgeon in the hospitals surveyed, as there were no subspecialty services in the region. Only one hospital had access to outpatient podiatry. Common themes identified around barriers faced in management of diabetes-related foot disease by clinicians were broadly centred around resource availability, awareness and education, and professional development. CONCLUSION: Despite the high prevalence of diabetes-related foot disease within PICTs, there appears to be a lack of functional multi-disciplinary foot services (MDFs). To improve the outcomes for diabetes-related foot disease patients in the region, there is a need to establish functional MDFs and engage international stakeholders to provide ongoing supports in the form of education, mentoring, as well as physical resources.

Use of simple lymphatic drainage on truncal lymphoedema for a patient with diabetes and peripheral arterial disease.

Lymphoedema is the gradual, abnormal build-up of lymph fluid in the tissues resulting from a failure of the lymphatic system. The swelling impedes movement and is painful. Compression garments are contraindicated and not tolerated by patients with extensive peripheral arterial disease. In this case study, simple lymphatic drainage was therefore considered a safer treatment option to reduce oedema and to encourage proactive self-management for a patient with bilateral amputations, diabetes and peripheral arterial disease.

A qualitative exploration of the experiences of Aboriginal and Torres Strait Islander people using a real-time video-based telehealth service for diabetes-related foot disease.

INTRODUCTION: Diabetes-related foot disease (DFD) is one of the most prevalent causes of global hospitalisation and morbidity, and it accounts for up to 75% of lower-extremity amputations globally. The 5-year mortality rate following any amputation ranges from 53% to 100%. Early identification of wounds and multidisciplinary management can reduce amputation rates by 39-56%. Rural and remote communities and Indigenous populations are disproportionately affected by DFD. This is reflected in amputation rates, which are much higher for Indigenous than for non-Indigenous Australians and for those in very remote areas than for those in major cities or inner regional areas. The large geographical spread of the population in Australia is a substantial barrier for those providing or accessing health services, particularly multidisciplinary and specialist services, which undoubtedly contributes to poorer DFD outcomes in rural and remote communities. METHODS: A real-time, video-based telehealth service for DFD management was established at the Royal Adelaide Hospital Vascular Services clinic to improve access to specialist services for rural and remote Aboriginal and Torres Strait Islander communities. An exploratory qualitative study that utilised one-on-one, semi-structured interviews was conducted with 11 participants who identified as Aboriginal and who had participated in the telehealth foot service. Interviews were transcribed, de-identified and analysed using thematic analysis, using an inductive approach. RESULTS: Four interrelated themes emerged. 'Practical benefits of staying home' describes the reduced burden of travel and advantages of having local healthcare providers and support people at consultations. 'Access to specialists and facilities' highlights how some participants felt that there was a lack of appropriate facilities in their area and appreciated the improved access telehealth provided. 'Feeling reassured that a specialist has seen their feet' reflects the positive impact on wellbeing that participants experienced when their feet were seen by specialist health staff. 'Facilitates communication' describes how participants felt included in consultations and how seeing a person on screen assisted conversation. CONCLUSION: The advantages of real-time, video-based telehealth go beyond reduced travel burden and improved access to specialist care. This model of care may facilitate relationship-building, patient wellbeing, and feelings of trust and safety for Aboriginal and Torres Strait Islander DFD patients.

Global trends in the incidence of hospital admissions for diabetes-related foot disease and amputations: a review of national rates in the 21st century.

AIMS/HYPOTHESIS: Diabetic foot disease (DFD) is a leading cause of hospital admissions and amputations. Global trends in diabetes-related amputations have been previously reviewed, but trends in hospital admissions for multiple other DFD conditions have not. This review analysed the published incidence of hospital admissions for DFD conditions (ulceration, infection, peripheral artery disease [PAD], neuropathy) and diabetes-related amputations (minor and major) in nationally representative populations. METHODS: PubMed and Embase were searched for peer-reviewed publications between 1 January 2001 and 5 May 2022 using the terms 'diabetes', 'DFD', 'amputation', 'incidence' and 'nation'. Search results were screened and publications reporting the incidence of hospital admissions for a DFD condition or a diabetes-related amputation among a population representative of a country were included. Key data were extracted from included publications and initial rates, end rates and relative trends over time summarised using medians (ranges). RESULTS: Of 2527 publications identified, 71 met the eligibility criteria, reporting admission rates for 27 countries (93% high-income countries). Of the included publications, 14 reported on DFD and 66 reported on amputation (nine reported both). The median (range) incidence of admissions per 1000 person-years with diabetes was 16.3 (8.4-36.6) for DFD conditions (5.1 [1.3-7.6] for ulceration; 5.6 [3.8-9.0] for infection; 2.5 [0.9-3.1] for PAD) and 3.1 (1.4-10.3) for amputations (1.2 [0.2-4.2] for major; 1.6 [0.3-4.3] for minor). The proportions of the reported populations with decreasing, stable and increasing admission trends were 80%, 20% and 0% for DFD conditions (50%, 0% and 50% for ulceration; 50%, 17% and 33% for infection; 67%, 0% and 33% for PAD) and 80%, 7% and 13% for amputations (80%, 17% and 3% for major; 52%, 15% and 33% for minor), respectively. CONCLUSIONS/INTERPRETATION: These findings suggest that hospital admission rates for all DFD conditions are considerably higher than those for amputations alone and, thus, the more common practice of reporting admission rates only for amputations may substantially underestimate the burden of DFD. While major amputation rates appear to be largely decreasing, this is not the case for hospital admissions for DFD conditions or minor amputation in many populations. However, true global conclusions are limited because of a lack of consistent definitions used to identify admission rates for DFD conditions and amputations, alongside a lack of data from low- and middle-income countries. We recommend that these areas are addressed in future studies. REGISTRATION: This review was registered in the Open Science Framework database ( https://doi.org/10.17605/OSF.IO/4TZFJ ).

Editor's Choice - A Systematic Review and Meta-Analysis of the Incidence and Risk Factors for Re-admission to Hospital in People with Diabetes Related Foot Disease.

OBJECTIVE: The aim of this study was to systematically review the incidence and risk factors for 30 day re-admission to hospital following an index admission to treat diabetes related foot disease (DFD). DATA SOURCES: A literature search was conducted using Medline/PubMed, Scopus, Cochrane Library, and CINAHL databases. METHODS: The study was performed according to the Preferred Reporting Items for Systematic Reviews and Meta-Analysis (PRISMA) guidelines. Studies that reported the rate of total or DFD related 30 day re-admissions were included. Meta-analysis was performed using a random effects model to calculate the pooled mean (95% confidence interval [CI]) of the proportion of patients re-admitted to hospital within 30 days. Meta-regression was performed to determine the association between risk factors and 30 day re-admission. RESULTS: Sixteen retrospective studies with a total of 124 683 participants were included. The mean total 30 day re-admission rate was 22.0% (95% CI 17.0 - 27.0%) while the mean DFD related 30 day re-admission rate was 10.0% (95% CI 7.0 - 15.0%). Meta-regression found that greater prevalence of peripheral neuropathy (p = .045) was associated with a higher rate of any 30 day re-admission, and male sex (p = .023) and private health insurance (p = .048) were associated with lower rates of any 30 day re-admission. Coronary artery disease (p= .025) was associated with a higher rate of DFD related re-admission. All studies had low or moderate risk of bias. CONCLUSION: This systematic review suggested that about one fifth of patients with DFD are re-admitted to hospital within 30 days, of which about half are to treat DFD. Risk factors for re-admission included female gender, peripheral neuropathy, lack of private health insurance, and coronary artery disease.

Cohort Study Examining the Presentation, Distribution, and Outcomes of Peripheral Artery Disease in Aboriginal, Torres Strait Islander, and Non-Indigenous Australians.

OBJECTIVE: This retrospective cohort study investigated the anatomical distribution, severity, and outcome of peripheral artery disease (PAD) in Aboriginal and Torres Strait Islanders compared with non-indigenous Australians. METHODS: The distribution, severity, and outcome of PAD were assessed using a validated angiographic scoring system and review of medical records in a cohort of Aboriginal and Torres Strait Islander and non-indigenous Australians. The relationship between ethnicity and PAD severity, distribution, and outcome were examined using non-parametric statistical tests, Kaplan-Meier and Cox proportional hazard analyses. RESULTS: Seventy-three Aboriginal and Torres Strait Islanders and 242 non-indigenous Australians were included and followed for a median of 6.7 [IQR 2.7, 9.3] years. Aboriginal and Torres Strait Islander patients were more likely to present with symptoms of chronic limb threatening ischaemia (81% vs. 25%; p < .001), had greater median [IQR] angiographic scores for the symptomatic limb (7 [5, 10] vs. 4 [2, 7]) and tibial arteries (5 [2, 6] vs. 2 [0, 4]) and had higher risk of major amputation (HR 6.1, 95% CI 3.6 - 10.5; p < .001) and major adverse cardiovascular events (HR 1.5, 95% CI 1.0 - 2.3; p = .036) but not for revascularisation (HR 0.8, 95% CI 0.5 - 1.3; p = .37) compared with non-indigenous Australians. The associations with major amputation and major adverse cardiovascular events were no longer statistically significant when adjusted for limb angiographic score. CONCLUSION: Compared with non-indigenous patients, Aboriginal and Torres Strait Islander Australians had more severe tibial artery disease and a higher risk of major amputation and major adverse cardiovascular events.

Weight-bearing physical activity in people with diabetes-related foot disease: A systematic review.

INTRODUCTION: Weight-bearing physical activity is important for people with diabetes-related foot disease but may also contribute to ulceration or delayed ulcer healing. No overview of weight-bearing activity of people at different stages of foot disease is available. We aimed to summarise quantitatively measured daily activity levels in people with diabetes-related foot disease. METHODS: We systematically searched peer-reviewed literature for studies reporting objectively measured weight-bearing activity in people with diabetes-related foot disease. We calculated daily step counts' means (over studies) and weighted means (over participants). International Working Group on the Diabetic Foot (IWGDF) risk strata, different climates, and activity indoors versus outdoors were compared. RESULTS: From 1247 publications, 27 were included. Mean steps/day in people with IWGDF risk 1/2: 6125 (12 studies; 345 participants; weighted mean: 5384). In IWGDF risk 3: 6167 (8 studies; 291 participants; weighted mean: 6239). In those with a foot ulcer: 4248 (6 studies; 186 participants; weighted mean: 4484). People living in temperate oceanic climates are more active compared to those in hotter or more humid climates (mean steps/day for no ulcer: 7712 vs. 5224 [18 studies]; for ulcer: 6819 vs. 2945 [6 studies]). People are more active indoors than outdoors (mean 4047 vs. 2514 [3 studies]). CONCLUSION: Levels of weight-bearing physical activity are similar between people with diabetes at various risk levels for foot ulceration but lower for those with a foot ulcer. Weight-bearing activity differs depending on the climatological environment and is higher indoors than outdoors. These findings provide reference for intervention studies or for clinicians aiming to provide mobility advice in this population.

Incidence, hospitalization and mortality and their changes over time in people with a first ever diabetic foot ulcer.

AIMS: A diabetic foot ulcer (DFU) is a severe condition associated with morbidity and mortality. Population-based studies are rare and limited by access to reliable data. Without this data, efforts in primary prevention cannot be evaluated. Therefore, we examined the incidence and changes over time for the first DFU in people with diabetes. We also examined hospitalization and all-cause mortality and their changes over time. METHODS: From the UK primary care CPRD GOLD database (2007-2017), we identified 129,624 people with diabetes by a prescription for insulin or a non-insulin anti-diabetic drug. DFUs were identified using Read codes and expressed as incidence rates (IRs). Changes over time were described using Poisson and logistic regression and expressed as incidence rate ratios (IRRs) and odds ratios (ORs) respectively. RESULTS: The mean IR of first registered DFUs was 2.5 [95% CI: 2.1-2.9] per 1000 person-years for people with type 2 diabetes and 1.6 [1.3-1.9] per 1000 person-years for people with type 1. The IRs declined for people with type 2 diabetes (IRR per year: 0.97 [0.96-0.99]), while no changes were observed for people with type 1 diabetes (IRR per year: 0.96 [0.89-1.04]). Average hospitalization and 1-year mortality risk for people with type 2 diabetes were 8.2% [SD: 4.7] and 11.7% [SD: 2.2] respectively. Both declined over time (OR: 0.89 [0.84, 0.94] and 0.94 [0.89, 0.99]). CONCLUSION: The decline in all IRs, hospitalizations and mortality in people with type 2 diabetes suggests that prevention and care of the first DFU has improved for this group in primary care in the UK.

Patients' and clinicians' perspectives on the clinical utility of the Rheumatoid Arthritis Foot Disease Activity Index.

Although patient-reported outcome measures (PROMs) are recommended in clinical practice, their application in routine care is limited. The Rheumatoid Arthritis Foot Disease Activity Index (RADAI-F5) is a validated PROM for assessing foot disease in rheumatoid arthritis (RA). To explore patient and clinician opinions and perceptions of the clinical utility of the Rheumatoid Arthritis Foot Disease Activity Index (RADAI-F5), eight RA patients and eight clinicians routinely involved in the management of RA patients participated in one semi-structured remote video-based interview. They provided their perspectives on the barriers and facilitators to clinical implementation of the RADAI-F5. Three global themes were identified; 'Feet are a priority' as the impact of RA on the feet negatively impacted upon patient quality of life. The second theme was 'Need for a clinically feasible foot PROM' as participants recognised the current lack of a clinically feasible tool to determine RA foot disease. The third global theme of 'Implementation' was drawn together to form two subordinate themes: 'Facilitators to RADAI-F5 implementation' as the tool can promote communication, guide management, help screen foot symptoms, monitor foot disease status and treatments, and promote patient education and; 'Barriers to RADAI-F5 implementation' as there were associated practical difficulties, including lack of appointment time, administrative burdens, IT barriers and preference for further RADAI-F5 validation using imaging. The RADAI-F5 has significant potential as a clinical tool to aid foot disease management. However, implementation challenges must be overcome before broad adoption in rheumatology clinics.

Macronutrient and micronutrient intake of individuals with diabetic foot ulceration: A short report.

BACKGROUND: Adequate nutrition is essential in individuals with diabetic foot ulceration (DFU); therefore, an assessment of dietary intake is critical. A lack of nutrients including protein, zinc and vitamins C and D have all been associated with poor wound healing. However, the comprehensive dietary intake of Australian adults with DFU is poorly understood. The aim of this cross-sectional study was to describe the dietary intake of adults with DFU in an Australian setting. METHODS: Participants (n = 115) with diabetes (type 1 and 2), a mean body mass index of 36 and current foot ulceration were recruited from across New South Wales, Australia. Dietary intake was assessed using the Australian Eating Survey, a self-reported validated food frequency questionnaire. RESULTS: The mean (SD) reported energy intake was 9.57 (±SD 4.43) MJ day-1 . A mean protein intake of 104 (±SD 49) g day-1 is below recommended intake for wound healing; however, the mean protein intake contribution to energy (19%E) was within recommendations for normal populations. The mean carbohydrate intake (43%E) was within recommended ranges for healthy populations; however, the mean total fat intake (36%E) was above recommendations. Micronutrient intake was adequate, apart from folate, which was below the recommended intake, and sodium, vitamin C, vitamin A and selenium, which were above the recommended intake. CONCLUSIONS: A lack of adequate folate may have a negative impact on healing, with folate proposed to play a role in tissue repair. Wound management of individuals with DFU should include a regular assessment of dietary intake to recognise deficiencies in macro- and micronutrients, and subsequently address these inadequacies to optimise healing.

Effectiveness of calcaneal osteotomy in surgical treatment of foot conditions: A Prisma statement guidelines compliant systematic review.

Calcaneal osteotomy is a commonly established method used to correct various foot malalignment surgery problems that produce varus and valgus hindfoot abnormality as well as Haglund's deformity, cavovarus foot reconstruction, flatfoot deformity, plantar fasciitis, posterior tibial tendon insufficiency and planovalgus foot. After decades, several procedures in orthopaedic foot surgery have been suggested for reducing the risk of wound and neurovascular complications. The goal of this Prisma statement guidelines compliant systematic review was to establish the effectiveness and safety of calcaneal osteotomy in foot surgery. We have performed a novel systematic review of the current published literature in order to evaluate the scientific evidence now available on this association, assigning predefined exclusion and inclusion criteria. Eight investigations were selected which had 191 cases. The adult flatfoot, tibialis posterior reconstruction and cavovarus foot deformity were treated with different procedures of calcaneal osteotomy techniques. The adequate level of effectiveness of calcaneal osteotomy is associated with the kind and location of the incision, with or without screw application, in each specific foot condition. There is a limited number of scientific investigations of the effectiveness and safety of the different kinds of calcaneal osteotomy in foot surgery, and there is the need to enhance outcome knowledge on this foot surgery technique.

Diabetic Foot Care: A Screening on Primary Care Providers' Attitude and Practice in Riyadh, Saudi Arabia.

Background and Objectives: Diabetic foot (DF) disease is one of the myriad complications of diabetes. Positive outcomes are expected through a multidisciplinary approach as provided by primary care providers (PCPs). This study aimed to assess the knowledge of DF and attitude of physicians in primary healthcare settings toward DF diagnosis and prevention in Saudi Arabia. Materials and Methods: This observational cross-sectional study used a self-administered questionnaire that was completed by family medicine consultants, residents, and general practitioners working in primary care settings in Riyadh. Results: Of the 152 physicians who completed the survey, (43.4%) completed more than 10 h of diabetes continuing medical education (CME) over the past three years. Most (96.1%) PCPs educate patients about foot self-inspection, and only (64.5%) perform foot inspection at every visit in high-risk diabetic foot patients. PCP knowledge about diagnosing and managing diabetic foot infection was suboptimal. Only 53.9% of participants reported performing a probe-to-bone in DF patients with open wounds. Conclusions: We identified knowledge and action gaps among PCPs. Physicians had acceptable knowledge about preventive measures. However, deficits were found regarding diagnosing and management of DF infections. We recommend addressing these knowledge gaps by incorporating DF lectures and workshops within family medicine conferences and residency programs.

Comparative analysis of patients with upper urinary tract urothelial carcinoma in black-foot disease endemic and non-endemic area.

BACKGROUND: A high incidence of upper urinary tract urothelial carcinoma has been reported in the southwestern area of Taiwan, where arsenic water contamination was considered the main cause. However, there is no definite proof to show a correlation between arsenic water contamination and upper urinary tract urothelial carcinoma. To investigate the clinical and epidemiological features of patients with upper urinary tract urothelial carcinoma between arsenic water endemic and non-endemic areas, we analyzed patients in terms of characteristics, stratified overall survival, disease-free survival, and cancer-specific survival. METHODS: The records of a total of 1194 patients diagnosed with upper urinary tract urothelial carcinoma were retrospectively reviewed. Clinical data and current medical status were collected from the medical records. Statistical analyses were performed to determine the clinical variables and stratified survival curves between endemic and non-endemic groups. RESULTS: Female predominance was revealed in both endemic and non-endemic groups (male:female ratio = 1:1.2-1.4). No statistical differences were found in histological types, staging, and tumor size between the two groups. Nonetheless, patients with characteristics of aging and having end-stage renal disease were outnumbered in the non-endemic group, while a higher prevalence of previous bladder tumors and more ureteral tumors were found in the endemic group. Adjusted stratified cumulative survival curves suggested a poorer prognosis in endemic patients, especially in disease-free survival of early stage disease. CONCLUSIONS: A higher mortality rate with more previous bladder cancer history and ureteral tumors was seen in patients with upper urinary tract urothelial carcinoma residing in the arsenic water contamination area. This may be attributed to the long-term carcinogenic effect of arsenic underground water.
