Abstract
The in-situ mechanical characterization of elastomers is not highly regarded due to the existence of a well-established set of sample-based standard tests for research and industry. However, there are certain situations or materials, like biological soft tissue, where an in-situ approach is necessary due to the impossibility of sampling from a living body. We have developed a dynamic mechanical analysis (DMA)-like device to approach in-vivo and in-situ multidimensional stress-strain properties of human plantar soft tissues. This work elucidates the operational mechanism of the novel measurement, with the definition of a new set of moduli, test standardization and protocol. Exploratory results of a volunteer's living plantar, silica rubber samples are presented with well preciseness and consistence as expected.

Abstract
Purpose This study determines barriers and facilitators to including people with lower limb amputation (LLA) in cardiovascular rehabilitation programmes (CRPs). Method Canadian CRP managers and exercise therapists were invited to complete a questionnaire. Results There were 87 respondents. Of the 32 CRP managers, 65.6% reported that people with LLA were eligible for referral, but of these, 61.9% only accepted people with LLA and cardiac disease, and 38.1% only accepted them with ≥ 1 cardiovascular risk factor. CRP eligibility progressively decreased as mobility severity increased, with 94% of programmes accepting those with mild mobility deficits but only 48% accepting those with severe deficits. Among therapists in CRPs that accepted LLAs, 54.3% reported not having an LLA participant within the past three years. Among all responding therapists and managers who were also therapists (n = 58), 43% lacked confidence in managing safety concerns, and 45%, 16%, and 7% lacked confidence in prescribing aerobic exercise to LLA with severe, moderate, and no mobility deficits respectively. There was a similar finding with prescribing resistance training. LLA-specific education had not been provided to any respondent within the past three years. The top barriers were lack of referrals (52.6%; 30) and lack of knowledge of the contraindications to exercise specific for LLA (43.1%; 31). Facilitators included the provision of a resistance-training tool kit (63.4%; 45), education on exercise safety (63.4%; 45), and indications for physician intervention/inspection (63.6%; 42). Conclusion Most of the CRPs surveyed only accept people with LLA if they have co-existing cardiac disease or cardiovascular risk factors. Few people with LLA participate. Education on CRP delivery for LLAs is needed to improve therapists' confidence and exercise safety.

Abstract
This study aims to investigate whether the current wound classifications were valid for the treatment prognosis of subjects treated for limb-threatening diabetic foot ulcers (LTDFU). A total of 1548 patients with LTDFU and infection were studied, with wounds recorded using the Wagner, Texas, PEDIS and WIfI classifications while major lower extremity amputations (LEAs) or in-hospital mortality incidences were defined as poor outcomes. Among them, 153 (9.9%) patients received major LEAs and 38 (2.5%) patients died. After adjustments, the Wagner classification and Texas stage as well as clinical factors such as comorbidity with major adverse cardiac events (MACE), being under dialysis and having serum levels of C-reactive protein (CRP) and albumin were independent factors for prognosis. For patients without dialysis, Wagner and Texas stage stood out independently for prognosis. For patients on dialysis, only levels of CRP (odds ratio [OR] = 2.2 in Wagner, OR = 2.0 in WIfI, OR = 2.2 in Texas, OR = 2.3 in PEDIS) and albumin (OR = 0.4 in four classifications) were valid predictors. The Wagner system and Texas stage were valid for predicting prognosis in treatment for LTDFUs, suggesting a role of vascular perfusion. MACE history, levels of CRP and albumin level should assist in prediction; more significantly, only levels of CRP and albumin appeared valid for those subjects undergoing dialysis.

Abstract
Diabetic foot ulcer (DFU), a common intractable chronic complication of diabetes mellitus (DM), has a prevalence of up to 25%, with more than 17% of the affected patients at risk of amputation or even death. Vascular risk factors, including vascular stenosis or occlusion, dyslipidemia, impaired neurosensory and motor function, and skin infection caused by trauma, all increase the risk of DFU in patients with diabetes. Therefore, diabetic foot is not a single pathogenesis. Preclinical studies have contributed greatly to the pathogenesis determination and efficacy evaluation of DFU. Many therapeutic tools are currently being investigated using DFU animal models for effective clinical translation. However, preclinical animal models that completely mimic the pathogenesis of DFU remain unexplored. Therefore, in this review, the preparation methods and evaluation criteria of DFU animal models with three major pathological mechanisms: neuropathy, angiopathy and DFU infection were discussed in detail. And the advantages and disadvantages of various DFU animal models for clinical sign simulation. Furthermore, the current status of vitro models of DFU and some preclinical studies have been transformed into clinical treatment programs, such as medical dressings, growth factor therapy, 3D bioprinting and pre-vascularization, Traditional Chinese Medicine treatment. However, because of the complexity of the pathological mechanism of DFU, the clinical transformation of DFU model still faces many challenges. We need to further optimize the existing preclinical studies of DFU to provide an effective animal platform for the future study of pathophysiology and clinical treatment of DFU.

Abstract
Diabetic foot ulcers are a significant complication of diabetes, affecting millions globally, and require appropriate antibiotics, surgical debridement, wound care, and metabolic optimization for management. This article presents an innovative hybrid regenerative therapy for reconstructing an infected, traumatized foot wound of a 62-year-old man with diabetes mellitus who presented with a week-old injury after a car accident. At presentation, he had a 14 × 10 cm dorsal foot wound with skin necrosis, pus discharge, and bony instability owing to partial fractures and joint dislocations. Antibiotics were administered to treat multidrug-resistant bacteria and followed by surgical debridement and the application of a portable Velnext negative pressure wound therapy device. Once the wound condition stabilized, hybrid regenerative therapy was performed weekly. Six milliliters platelet-rich plasma and 6 mL platelet-poor plasma were prepared from 27 mL of venous blood mixed with 3 mL sodium citrate and injected into the tendons, soft-tissues, and muscles. Next, the exposed bones and tendons were covered with platelet-rich fibrin and semi-occlusive membranes, and a Velnext negative pressure wound therapy device was applied over them. The wound improved progressively during the subsequent 6 weeks and was finally covered with a split-skin graft. The patient had a successful 18-month postoperative period until now with stable grafts, anatomical restoration, and excellent foot functionality. Thus, hybrid regenerative therapy, encompassing several prevalent methods for healing wounds, has excellent benefits for treating complex diabetic foot ulcers.

Abstract
INTRODUCTION Repetitive minor amputations carry the concomitant risks of multiple surgical procedures, major amputations have physical and economical major drawbacks. The aim of this study was to evaluate whether there is a distinct number of minor amputations predicting a major amputation in the same leg and to determine risk factors for major amputation in multiple minor amputations. MATERIALS AND METHODS A retrospective chart review including 429 patients with 534 index minor amputations between 07/1984 and 06/2019 was conducted. Patient demographics and clinical data including number and level of re-amputations were extracted from medical records and statistically analyzed. RESULTS 290 legs (54.3%) had one or multiple re-amputations after index minor amputation. 89 (16.7%) legs needed major amputation during follow up. Major amputation was performed at a mean of 32.5 (range 0 - 275.2) months after index minor amputation. No particular re-amputation demonstrated statistically significant elevated odds ratio (a.) to be a major amputation compared to the preceding amputation and (b.) to lead to a major amputation at any point during follow up. Stepwise multivariate Cox regression analysis revealed minor re-amputation within 90 days (HR 3.8, 95% CI 2.0-7.3, p <0.001) as the only risk factor for major amputation if at least one re-amputation had to be performed. CONCLUSIONS There is no distinct number of prior minor amputations in one leg that would justify a major amputation on its own. If a re-amputation has to be done, the timepoint needs to be considered as re-amputations within 90 days carry a fourfold risk for major amputation. LEVEL OF EVIDENCE Retrospective comparative study (Level III).

Abstract
Introduction Knee pain can impact the performance of activities and sports participation in children. Dynamic knee valgus is a movement pattern commonly related to health conditions that may be associated with sex and foot kinematics in children. Objective To assess the prevalence of dynamic knee valgus and its relationship with foot mobility, sex, and knee pain in children. Method A cross-sectional observational study was carried out with 144 children (10-18 years old). The pain level was investigated using the Visual Analog Pain Scale and categorized into no pain/minor pain (≤2 cm), moderate pain (3-4,9 cm), and severe pain (≥5.0 cm). Foot mobility was assessed using the adapted navicular drop test and categorized into poor/adequate foot mobility (0.0 cm-0.9 cm) and greater foot mobility (≥1.0 cm). The dynamic knee valgus presence was checked using the step-down test. The association analysis was performed using simple tabulation considering the cluster effect. The Prevalence Ratios and the respective confidence intervals (95%) were estimated from Multiple Poisson Regression with robust variance. A significance level of 5% was adopted. Results The dynamic knee valgus prevalence was 26.3% and 26.9% in the right and left lower limbs, respectively. Females presented greater dynamic knee valgus frequency in the left lower limb than males. The dynamic knee valgus presence in males was associated with foot mobility in right (p = 0.001) (Prevalence Ratio: 9.33 Confidence Interval: 2.93-29.72) and left lower limbs (p = 0.003) (Prevalence Ratio: 6.25 Confidence Interval: 1.7-22.62). Conclusion Male and female children showed different relationships of the analyzed factors, suggesting that characteristics related to sex may impact the aspects linked to dynamic knee in children.

Abstract
AIMS A number of reports have illustrated the barriers that the war in Ukraine puts to diabetes care. While their recommendations are valuable for glycemic control and the prevention or early detection of life - threatening diabetes complications, such as hypoglycemia and ketoacidosis, the discourse on diabetic foot is limited. This letter emphasizes the implications of the war in diabetic foot care and discusses potential solutions. METHODS The authors searched peer - reviewed and grey literature to identify records related to the prevalence of diabetic foot in Ukraine and the standards of care before and after the invasion of Ukraine. RESULTS Thousands of people in Ukraine sustain diabetic foot ulcers and, thus, are at high risk for lower limb amputations due to the limited access to healthcare services in the country. If not addressed, disability associated with chronic ulcers and amputations can severely affect individual and public health in Ukraine. Strengthening primary and remote care, educating people on self - care and providing adequate supplies for the management of diabetic foot have a major potential to prevent amputations, disability and death. CONCLUSIONS Providing adequate diabetic foot care in Ukraine and other regions tormented by armed conflicts is vital for the health of the local population and the potential of the affected countries to recover after the crisis.

Abstract
The human skin serves as the body’s first line of defense against the environment. Diabetes mellitus (DM) and 2nd–4th degree burns, on the other hand, affect the skin’s protective barrier features. Burn wounds, hypermetabolic state, and hyperglycemia compromise the
immune system leading to chronic wound healing. Unlike acute wound healing processes, chronic wounds are affected by reinfections which can lead to limb amputation or death. The conventional wound dressing techniques used to protect the wound and provide an optimal environment for repair have
their limitations. Various nanomaterials have been produced that exhibit distinct features to tackle issues affecting wound repair mechanisms. This review discusses the emerging technologies that have been designed to improve wound care upon skin injury. To ensure rapid healing and possibly
prevent scarring, different nanomaterials can be applied at different stages of healing (hemostasis, inflammation, proliferation, remodeling).

Abstract
Background The concept of person-centred care is embedded within healthcare policy, focusing on long-term conditions and multimorbidity. The evidence that person-centred care is being operationalised effectively across all areas of healthcare is limited. The aim of this scoping review was to explore the application, features, and effectiveness of person-centred care with service-users, carers, and the community within podiatry. Methods The scoping review was based upon Arksey and Malley’s five stage framework. The following databases were searched between January 2010 and March 2021: AMED, CINAHL, Embase, Cochrane library, SocINDEX, British Education Index, Business Source Complete, MEDLINE (EBSCO), and the EThOS 'Global electronic thesis and dissertation' repository, Prospero, and reference lists of included papers. Primary research articles were included if they reported on a person-centred care focused intervention with podiatry. Research terms were developed, appropriate databases identified, and an initial search resulted in 622 papers which, following removal of duplicates and critical appraisal, resulted in 18 eligible papers. Data extracted involved the types of person-centred care utilised, intervention details, motivations for engaging in person-centred care interventions, and intervention barriers and challenges. Results Eighteen articles were included in the review. The main type of person-centred care utilised was patient/carer activities around self-management. None of the studies considered the role of the podiatrist as a person-centred care agent. The data on interventions generated the following themes ‘service facilitated person-centred care’ where a change has been made to service delivery, ‘direct clinician delivery’ where the intervention is delivered by the clinician with the patient present and ‘patient instigated participation’ where patient motivation is required to engage with an activity beyond the consultation. Outcome measures associated with quality of care and effectiveness were absent. Conclusion There is a lack of congruency between the concept of person-centred care and how it is operationalised. A whole system approach that considers commissioning, organisational leadership, the role of the practitioners and patients has not been considered. There is immense scope for the podiatrist to play an important part in the personalised-care agenda, but currently research that can evidence the effectiveness of person-centred care in podiatry is absent.

Abstract
Diabetes distal symmetrical peripheral neuropathy (DSPN) is the most prevalent form of neuropathy in industrialized countries, substantially increasing risk for morbidity and pre-mature mortality. DSPN may manifest with small-fiber disease, large-fiber disease, or a combination of both. This review summarizes: (1) DSPN subtypes (small- and large-fiber disease) with attention to clinical signs and patient symptoms; and (2) technological diagnosis and screening for large- and small-fiber disease with inclusion of a comprehensive literature review of published studies from 2015-present (N = 66). Review findings, informed by the most up-to-date research, advance critical understanding of DSPN large- and small-fiber screening technologies, including those designed for point-of-care use in primary care and endocrinology practices.

Hung S, Chiu C, Huang C, Lin C, Yeh J, Yang H, Huang Y. Impact of wound microbiology on limb preservation in patients with diabetic foot infection. J Diabetes Investig 2022; 13:336-343.

Abstract
AIMS/INTRODUCTION To investigate the association between specific bacterial pathogens and treatment outcome in patients with limb-threatening diabetic foot infection (LT-DFI). MATERIALS AND METHODS Consecutive patients treated for LT-DFI in a major diabetic foot center in Taiwan were analyzed between the years 2014 and 2017. Patients with positive wound culture results at first aid were enrolled. Clinical factors, laboratory data, and wound culture results were compared. Lower-extremity amputations and in-hospital mortality were defined as a poor outcome. RESULTS Among the 558 patients, 272 (48.7%) patients had lower extremity amputation and 22 (3.9%) patients had in-hospital mortality. Gram-negative bacterial (GNB) infection was the independent factor following factors adjustment. When all the 31 microorganisms were analyzed, only E. coli (adjusted odds ratio [aOR], 3.01; 95% CI, 1.60-5.65), Proteus spp. (aOR, 2.99; 95% CI, 1.69-5.29), and Pseudomonas aeruginosa (aOR, 2.00; 95% CI 1.20-3.32) were associated with poor outcome. The analysis of specific GNB species in association with major- or minor- amputation have been reported. No specific pathogen was associated with cause of death in patients with mortality within 30 days. The antimicrobial-resistant strains were not associated with a poor treatment outcome. CONCLUSIONS The presence of GNB was associated with limb amputations. This study provides insight into more timely and appropriate management of the diabetic foot infection.

Abstract
Non-healing wounds are devastating for patients, potentially causing long-term morbidity and an impaired quality of life. They also incur a huge health economic burden for health-care services. Understanding of the causes of non-healing wounds has increased significantly. While the need to address the underlying aetiology has always been acknowledged, the role of biofilm in delaying or preventing healing is now accepted. There is a consensus on the need to debride the wound to remove biofilm and then prevent its reformation, to kickstart healing. The potential benefits of incorporating an antibiofilm component within the wound bed preparation framework are clear. However, such a strategy needs to be flexible enough so that it can be implemented by all practitioners, regardless of their expertise or specialty. Wound Hygiene does this. This supplement describes the Wound Hygiene protocol, and includes a selection of case studies on different wound types, demonstrating its ease of use and effectiveness in clinical practice.

Abstract
Background: Diabetic foot is one of major complication in diabetes patients with
unfavorable outcome. Survival study in outpatients is limited and factors
related are inconsistent. Survival and its modifiable risk factors should be
identified early since the foot at risk status to reduce
amputation/mortality in type 2 diabetes mellitus (T2DM). Objective: The aims of this study were to investigate survival probability for
amputation or mortality, compare different ulcer risk classification, and
figure out the relation of status of ulcer risk, age, gender, diabetes
duration, body mass index, fasting plasma glucose, HbA1C, and LDL with
amputation or mortality. Methods: This is a retrospective cohort study of 487 T2DM subjects who visited
internal medicine outpatient clinic in Fatmawati General Hospital since
January-December 2016. Status of ulcer risk and risk factors were extracted
from medical record and lower-extremity amputation or mortality was observed
in 3 years from baseline. Result: Three years overall survival is 85.7% (SE 0.17). Patients with high risk for
foot ulcer have survival probability of 80.2% (SE 0.027), which is lower
compared to non-high risk for foot ulcer with survival probability of 91.8%
(SE 0.019). Patients with high risk for foot ulcer (aHR 2.386 [95% CI
1.356-4.20]; P = .003), aged ≥60 years old (aHR 2.051 [95%
CI 1.173-3.585]; P = .012), and HbA1C ≥7% (aHR 2.022 [95%
CI 1.067-3.830]; P = .031) were independently associated
with amputation or mortality. Conclusion: T2DM patients with high risk for foot ulcer have lower survival probability
and higher risk for amputation or mortality in 3 years compared to patients
with non-high risk for foot ulcer. Status of ulcer risk, age ≥60 years, and
HbA1C ≥7% were associated with amputation or mortality in 3 years
observation.

Abstract
Infected cutaneous ulcers from diabetic rats with Candida albicans and Streptococcus aureus were treated with spray formulations containing green silver nanoparticles (GS), chemical silver nanoparticles (CS), or pomegranate peel extract (PS). After wound development and infection, the treatments were performed twice per day for 14 days. The wound healing was analyzed on days 2, 7, and 14 through the determination of CFUs, inflammatory infiltrate, angiogenesis, fibroplasia, myeloperoxidase, and collagen determination. Expressive improvement in wound healing was noted using both silver nanoparticles for 7 days. All the treatments were superior to controls and promoted significant S. aureus reduction after 14 days. CS presented better anti-inflammatory results, and GS and CS the highest number of fibroblasts. Despite the techniques' limitations, GS and CS demonstrated considerable potential for managing infected wounds, especially considering no early strategies prior to the drugs, such as the debridement of these wounds, were included.

Abstract
Background and Objectives: To propose a new classification of diabetic foot syndrome adapted for inclusion in the ICD-10 (the ICD-10 is the 10th revision of the International Statistical Classification of Diseases) and providing more reliable data on the number of clinical cases. Materials and Methods: A randomized controlled trial was performed. A total of 180 patients (36.6%) discharged from the hospital after surgical treatment and 312 patients (63.4%) who applied independently were observed and analysed. All patients had type 2 diabetes and were comparable in gender, age, duration of diabetes, area and nature of the wound defect. Results: We proposed to add the following to the existing ICD-10 and the emerging ICD-11 codes: Edf10.0-insulin-dependent diabetes mellitus with diabetic foot syndrome and Edf11.0-non-insulin-dependent diabetes mellitus with diabetic foot syndrome, where "df" is an acronym for diabetic foot. The new classification designates the seven most frequent areas of the lesion and five degrees of depth of soft tissue lesions. Conclusions: The proposed classification adapted for ICD-10 will enable the standardisation of diagnosis, providing a complete picture of this complication of diabetes mellitus, determining the number of amputations and their validity. Accurate statistics will allow for objective funding and timely preventive measures.

Abstract
AIM The purpose of this clinical trial was to evaluate the safety and efficacy of a fetal bovine acellular dermal matrix (FBADM) plus standard of care (SOC) for treating hard-to-heal diabetic foot ulcers (DFUs). METHOD A prospective, multi-centre, randomised controlled trial was carried out. The study included a 2-week run-in period, a 12-week treatment phase and a 4-week follow-up phase. The primary endpoint was complete wound closure at 12 weeks. RESULTS Twenty-one US sites enrolled and randomised 226 patients with hard-to-heal DFUs. The study was terminated early due to the COVID-19 pandemic, which led to a modified intent-to-treat (mITT) population of 207 patients, with 103 in the FBADM group and 104 in the SOC group. Of these participants, 161 completed the study per protocol (mPP population), with 79 receiving FBADM, and 82 without. At the first analysis point, patients treated with FBADM were found to be significantly more likely to achieve complete wound closure compared with SOC alone (mITT: 45.6% versus 27.9% p=0.008; mPP: 59.5% versus 35.6% p=0.002). The difference in outcome yielded an odds ratio of 2.2 (95% confidence interval (CI): 1.2, 3.9; p=0.008). Median time to closure within 12 weeks was 43 days for the FBADM group compared to 57 days for the SOC group (p=0.36). The median number of applications of FBADM to achieve closure was one. Adverse events were similar between groups and no product-related serious adverse events occurred. CONCLUSIONS These results indicate that in many cases a single application of FBADM in conjunction with SOC offers a safe, faster and more effective treatment of DFUs than SOC alone.

Abstract
Chronic wounds that lead to major lower extremity amputation have immense consequences on quality of life, and ultimately, mortality. However, mortality rates after lower extremity amputation for a chronic wound are broad within the literature and have escaped precise definition. This systematic review aims to quantify long-term mortality rates after major lower extremity amputation in the chronic wound population available in the existing literature. Ovid MEDLINE was searched for publications which provided mortality data after major, nontraumatic, primary lower extremity amputations. Lower extremity amputations were defined as below and above the knee amputation. Data from included studies was analyzed to obtain pooled 1-, 2-, 3-, 5- and 10-year mortality rates. Sixty-one studies satisfied inclusion criteria representing 36,037 patients who underwent nontraumatic major lower extremity amputation. Pooled mortality rates were 33.7%, 51.5%, 53%, 64.4%, and 80% at 1-, 2-, 3-, 5- and 10-year follow-up, respectively. Within the 8184 diabetic patients (types 1 and 2), 1- and 5-year mortality was 27.3% and 63.2%. Sources of mortality data were varied and included electronic medical records, national health and insurance registries, and government databases. Mortality after nontraumatic major lower extremity amputation is high, both in patients with diabetes as well as those without. Methods used to measure and report mortality are inconsistent, lack reliability, and may underestimate true mortality rates. These findings illustrate the need for a paradigm shift in wound management and improved outcomes reporting. A focus on amputation prevention and care within a multidisciplinary team is critical for recalcitrant ulcers.

Abstract
Introduction: An acute diabetic foot infection (DFI) is a serious condition and a leading cause of hospitalization and major amputation in patients with diabetes. Aim of this study was to evaluate the long term survival and risk factors for death and amputation after the DFI requiring hospital treatment. Materials and Methods: A retrospective study included all adult patients hospitalized for DFI treatments during 2010–2014. Overall survival (OS) and amputation free survival (AFS) (without major amputation) was calculated. We performed a Cox regression analysis of several clinical parameters to evaluate the effects of clinical parameters on overall and amputation-free survival. Results: Total of 324 patients with mean age of 66.8 (SD 12.8) years were included. The one- and five-year OS after DFI 81.2% (95%CI 77.5–84.9%) and 49.7% (95%CI 44.8–54.6%), respectively. Major amputation, wound ischemia, older age, and a low glomerular filtration rate reduced the OS after DFI. After a major amputation, the one- and five-year OS was 41.7% (95%CI 13.9–69.5) and 8.3% (95%CI 0.0–24.0%), respectively. Wound ischemia, older age, and elevated C-reactive protein reduced AFS. In contrast, hypertensive medication use was identified as a protective factor. Conclusion: Mortality after a DFI remains high and is significantly increased after a major amputation. Findings highlight the importance of early wound and ischemia management for DFI prevention.

Abstract
We analyzed a retrospective cohort of 150 patients with diabetic foot infections (DFIs) who underwent surgical treatment to determine long-term outcomes. The median follow-up of the series was 7.6 years. Cox's proportional hazards model for survival time was performed and hazard ratios (HRs) were estimated. Survival times were plotted using the Kaplan-Meier method. Fifteen patients (10%) required readmission after discharge from the hospital for a recurrence of the infection. Ninety patients (60%) had re-ulcerations. Forty-nine (54.4% of those re-ulcerated) required new admission and 24 of them (26.6% of those re-ulcerated) finally required a new amputation. Overall cumulative survival rates at 1, 5, and 8 years were 95%, 78%, and 64%, respectively. Predictive variables of long-term mortality were insulin treatment (HR: 2.0, 95% CI: 1.1-3.6, P = .01), female sex (HR: 3.1, 95% CI: 1.7-5.3, P<.01) and estimated glomerular filtration rate (eGFR) <60 ml/min/1.73 m2 (HR: 2.2, 95% CI: 1.1-4.2, P = .01). In conclusion, patients undergoing surgical treatment for DFIs had a high rate of recurrences and mortality. Women, patients who underwent treatment with insulin, and those with eGFR <60 ml/min/1.73 m2 had a higher risk of long-term mortality.

Abstract
BACKGROUND With growing global prevalence of diabetes mellitus, diabetes-related foot disease (DFD) is contributing significantly to disease burden. As more healthcare resources are being dedicated to the management of DFD, service design and delivery is being scrutinised. Through a national survey, this study aimed to investigate the current characteristics of services which treat patients with DFD in Australia. METHODS An online survey was distributed to all 195 Australian members of the Australian and New Zealand Society for Vascular Surgery investigating aspects of DFD management in each member's institution. RESULTS From the survey, 52 responses were received (26.7%). A multidisciplinary diabetes foot unit (MDFU) was available in more than half of respondent's institutions, most of which were tertiary hospitals. The common components of MDFU were identified as podiatrists, endocrinologists, vascular surgeons and infectious disease physicians. Many respondents identified vascular surgery as being the primary admitting specialty for DFD patients that require hospitalisation (33/52, 63.5%). This finding was consistent even in centres with MDFU clinics. Less than one third of MDFUs had independent admission rights. CONCLUSIONS The present study suggests that many tertiary centres in Australia provide their diabetic foot service in a multidisciplinary environment however their composition and function remain heterogeneous. These findings provide an opportunity to evaluate current practice and, to initiate strategies aimed to improve outcomes of patients with DFD.

Abstract
PURPOSE Predictors of outcome of diabetic foot ulcer (DFU) are important to improve the management of patients. Aim of the study was to find these predictors in type 2 diabetic patients with DFU. METHODS We recruited 583 patients. They were followed-up by a multidisciplinary team. A holistic and conservative approach was used and all risk factors and co-morbidities were aggressively treated. RESULTS During the follow-up period, 79.6% of patients healed in a mean time of 7.6 ± 3.8 months, 6.9% showed DFU persistence, 9.9% had minor amputations, and 3.6% experienced major amputation. Seventeen percent of the patients died. Among patients who healed, 37.1% of them showed DFU recurrence. Impairment of renal function was associated to DFU persistence, amputation, and mortality. Previous cardiovascular disease predicted DFU persistence, DFU recurrence, and mortality. Lower BMI predicted DFU persistence and mortality. Osteomyelitis was a predictor of amputation and death. Markers of peripheral artery disease (PAD) predicted minor amputation and DFU recurrence. Our study shows a relatively low incidence of complications of DFU. CONCLUSIONS Some predictors of outcome of DFU were confirmed and new predictors, like BMI and markers of PAD, were found. Our new findings suggest future strategies for nutrition support and revascularization. In addition, a holistic and conservative approach may improve the prognosis.

Abstract
BACKGROUND Diabetes foot self-care is one of the self-management behaviors of diabetic patients leading to a reduction in the incidence of pressure ulcers and amputation. Having a valid, reliable, simple and comprehensive tool is essential in measuring the self-care behavior of diabetic patients. The aim of this study was to evaluate the psychometric properties of the Farsi version of the diabetes foot self-care bahavior scale (DFSBS) in Iran. METHODS In this cross-sectional and methodological study, 500 patients with type 2 diabetes were recruited by convenience sampling. Construct validity was assessed by exploratory factor analysis (over 300 patients) and confirmatory factor analysis (over 200 patients). Internal consistency was calculated by Cronbach's alpha coefficient and its stability was calculated by intraclass correlation coefficient (ICC). RESULTS In the exploratory factor analysis, two self-care factors related to feet and shoes were extracted which had specific values of 38.49 and 1.24, respectively, and were able to account for 56.22% of the total self-care variance of diabetes foot. Confirmatory factor analysis had excellent fit model. The internal consistency and ICC of the whole instrument were 0.83 and 0.791 (95% CI: 0.575-0.925; P < 0.001), respectively. CONCLUSIONS The Farsi version of DFSBS (F-DFSBS) has good validity and reliability, and due to its appropriate psychometric properties, this tool can be used in future studies.

Abstract
OBJECTIVE Foot complications in patients with diabetes or peripheral artery disease (PAD) are serious events in the life of these patients that often lead to amputations and mortality. No evidence synthesis has been reported on the mortality rates after minor lower extremity amputation; thus, a quantitative evidence synthesis was needed. METHODS A systematic literature search was performed to identify studies that had reported the survival or mortality rates after a minor LEA. The studies were required to include one or more of the following primary outcomes: mortality rate at 30 days, 1 year, 3 years, 5 years, 6 to 7 years, or 8 to 9 years. The secondary outcomes were the mortality rates according to the anatomic location of the amputation in the foot and the independent risk factors for mortality. RESULTS A total of 28 studies with 17,325 subjects fulfilled the inclusion criteria. The meta-analytical results of the mortality rates were as follows: 3.5% at 1 month, 20% at 1 year, 28% at 3 years, 44.1% at 5 years, 51.3% at 6 to 7 years, and 58.5% at 8 to 9 years. From these studies of diabetic patients, age was the most consistent independent risk factor, followed by chronic kidney disease, PAD, and coronary artery disease. One study of patients with PAD had reported diabetes as an independent risk factor for mortality. The subgroup analysis of the four studies reporting the outcomes of patients with PAD showed greater 3- and 5-year mortality rates compared with the overall and "diabetic" results. CONCLUSIONS Mortality after minor amputation for patients with diabetes and/or PAD was found to be very high. Compared with the reported cancer data, survival was worse than that for many cancers. Just as in the case of major amputations, minor amputations should be considered a pivotal event in the life of these patients.

Abstract
BACKGROUND Amputations are associated with markedly reduced long-term survival in patients with diabetic foot disease. However, there is paucity of long-term survival data in published literature. METHODS We searched the electronic case records and laboratory details of patients who underwent amputations between 1997 and 2006 to obtain at least 10 years of follow up data after the surgery to assess the survival rates and possible risk factors reducing survival in the year 2016. Amputation level below ankle was considered as minor and above ankle as major amputations. RESULTS Of the 233 cases (159 males; median age 68 years), 161 had major amputations. Of the 72 cases who had minor amputations initially, 63 needed a further amputation or contralateral amputation on follow up. One hundred seventy-seven patients (76%) were not alive after 10 years of follow up. The survival rates at 1, 3, 5, 7, and ≥10 years were 64%, 50%, 40%, 34%, and 24%, respectively. Maximum number of deaths occurred within 4 months of amputations. There was no difference between survival rates following major or minor amputations and among males or females. The only statistically significant parameter affecting lower survival rate was age ≥70 years, with each additional year of age increasing the hazard by a factor of 1.039 (95% CI: 1.024-1.054) or 3.9% (2.4-5.4%). CONCLUSIONS Five-year and 10-year survival rates were 40% and 24%, respectively, following diabetic foot amputations. Higher age ≥70 years was associated with lower survival rate compared with younger age groups after lower extremity amputations.

Abstract
BACKGROUND In 2007, we reported a summary of data comparing diabetic foot complications to cancer. The purpose of this brief report was to refresh this with the best available data as they currently exist. Since that time, more reports have emerged both on cancer mortality and mortality associated with diabetic foot ulcer (DFU), Charcot arthropathy, and diabetes-associated lower extremity amputation. METHODS We collected data reporting 5-year mortality from studies published following 2007 and calculated a pooled mean. We evaluated data from DFU, Charcot arthropathy and lower extremity amputation. We dichotomized high and low amputation as proximal and distal to the ankle, respectively. This was compared with cancer mortality as reported by the American Cancer Society and the National Cancer Institute. RESULTS Five year mortality for Charcot, DFU, minor and major amputations were 29.0, 30.5, 46.2 and 56.6%, respectively. This is compared to 9.0% for breast cancer and 80.0% for lung cancer. 5 year pooled mortality for all reported cancer was 31.0%. Direct costs of care for diabetes in general was $237 billion in 2017. This is compared to $80 billion for cancer in 2015. As up to one-third of the direct costs of care for diabetes may be attributed to the lower extremity, these are also readily comparable. CONCLUSION Diabetic lower extremity complications remain enormously burdensome. Most notably, DFU and LEA appear to be more than just a marker of poor health. They are independent risk factors associated with premature death. While advances continue to improve outcomes of care for people with DFU and amputation, efforts should be directed at primary prevention as well as those for patients in diabetic foot ulcer remission to maximize ulcer-free, hospital-free and activity-rich days.

Abstract
Background One Australian loses a limb every 3 h as a result of infected diabetic foot ulcers (DFU). This common condition accounts for substantial morbidity and mortality for affected individuals and heavy economic costs for the health sector and the community. There is an urgent need to test interventions that improve wound healing time, prevent amputations and recurrent ulceration in patients presenting with DFU whilst improving quality of life and reducing health care costs. Methods One hundred and fifty eligible participants will be randomised to receive an autologous skin cell suspension, also termed 'spray-on' skin (ReCell®) or standard care interventions for their DFU. The primary outcome is complete wound healing at 6 months, but participants will be followed up for a total of 12 months to enable secondary outcomes including total overall costs, ulcer free days at 12 months and quality of life to be assessed. Discussion Outpatient costs for dressings, home nursing visits and outpatient appointments are key cost drivers for DFU. If spray-on skin is effective, large cost savings to WA Health will be realised immediately through a shortened time to healing, and through a higher proportion of patients achieving complete healing. Shortened healing times may enable participants to return to work earlier. Any economic benefits are likely to be amplified across Australia and other similar demographic settings where aging populations with increased diabetes rates are considered major future challenges.

Abstract
Acute necrotising diabetic foot (DF) infections are common, costly, and do not infrequently result in debilitating major lower-extremity amputations. Dakin's solution is a long-standing topical antiseptic that has shown benefit in this clinical setting, but its use is undermined by a presumed risk of cytotoxicity. In this single-centre case series, we retrospectively evaluated 24 patients with severe necrotising DF infections treated with a cyclical instillation of Dakin's solution at a referral multidisciplinary DF unit. Most patients achieved favourable outcomes in infection control and limb salvage, with only one patient (4.2%) requiring a major (at or above-the-ankle) amputation. The mean time to complete or near-complete wound granulation was 5.4 weeks. Of the 12 patients who completed 12 or more months of longitudinal follow up, only 2 (12.2%) had a wound recurrence. In this severe DF infection patient cohort, Dakin's solution led to a clinically meaningful improvement. No remarkable impairment in the wound-healing process was observed.

Abstract
Diabetic foot infection (DFI) is a major complication of diabetic foot that lead to nontraumatic lower-extremity amputation (LEA). Such distal infection of the body having systemic inflammatory response syndrome (SIRS) is rarely reported. Consecutive patients treated for limb-threatening DFI in a major diabetic foot center in Taiwan were analyzed between the years 2014 to 2017. Clinical factors, laboratory data, perfusion, extent, depth, infection and sensation (PEDIS) wound score in 519 subjects with grade 3 DFI and 203 presenting SIRS (28.1%) were compared. Major LEA and in-hospital mortality were defined as poor prognosis. Patients presenting SIRS had poor prognosis compared with those with grade 3 DFI (14.3% versus 6.6% for major LEA and 6.4% versus 3.5% for in-hospital mortality). Age, wound size, and HbA1c were independent risk factors favoring SIRS presentation. Perfusion grade 3 (odds ratio 3.37, p = 0.044) and history of major adverse cardiac events (OR 2.41, p = 0.036) were the independent factors for poor prognosis in treating patients with DFI presenting SIRS. SIRS when presented in patients with DFI is not only limb- but life-threatening as well. Clinicians should be aware of the clinical factors that are prone to develop and those affecting the prognosis in treating patients with limb-threatening foot infections.

Abstract
Purpose Diabetic foot wound (DFW) is known as a major contributor of nontraumatic lower extremity amputation. We aimed to evaluate overall amputation rates and risk factors for amputation in patients with DFW. Materials and Methods From January 2014 to December 2017, 141 patients with DFW were enrolled. We determined rates and risk factors of major amputation in DFW and in DFW with peripheral arterial occlusive disease (PAOD). In addition, we investigated rates and predictors for amputation in diabetic foot ulcer (DFU). Results The overall rate of major amputation was 26.2% in patients with DFW. Among 141 DFWs, 76 patients (53.9%) had PAOD and 29 patients (38.2%) of 76 DFWs with PAOD underwent major amputation. Wound state according to Wagner classification, congestive heart failure, leukocytosis, dementia, and PAOD were the significant risk factors for major amputation. In DFW with PAOD, Wagner classification grades and leukocytosis were the predictors for major amputation. In addition, amputation was performed for 28 patients (38.4%) while major amputation was performed for 5 patients (6.8%) of 73 DFUs. Only the presence of osteomyelitis (OM) showed significant difference for amputation in DFU. Conclusion This study represented that approximately a quarter of DFWs underwent major amputation. Moreover, over half of DFW patients had PAOD and about 38.2% of them underwent major amputation. Wound state and PAOD was major predictors for major amputation in DFW. Systemic factors, such as CHF, leukocytosis, and dementia were identified as risk factors for major amputation. In terms of DFU, 38.4% underwent amputation and the presence of OM was a determinant for amputation.

Heat Shock Protein 70 Gene Single Nucleotide Polymorphism and Diabetic Foot Ulcer. Is There Any Relationship? J Clin Med 2018; 7:jcm7080187. [PMID: 30060485 PMCID: PMC6111513 DOI: 10.3390/jcm7080187] [Citation(s) in RCA: 5] [Impact Index Per Article: 0.8] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/29/2018] [Revised: 07/24/2018] [Accepted: 07/24/2018] [Indexed: 12/16/2022] Open
Abstract
Objective: The study aims to investigate the potential role of C2437T (Met493Thr) single nucleotide polymorphism (SNP) of the heat shock protein (HSP) 70 in diabetic foot ulcer patients. Methods: In this prospective cohort study, SNP of the HSP70 hom gene, also called HSPA1L, was studied among diabetic patients with an ulcer (Group A: n = 50), diabetic patients without an ulcer (Group B: n = 50), and healthy subjects (Group C: n = 50). Results: There was a higher frequency of T/T genotype in group A (76%) as compared to group B (44%) and group C (14%). Moreover, the frequency of T allele was 7.3% in group A, 5.5% in group B, and 3.9% in group C. C allele frequency was 2.6%, 4.4%, and 6.1% in group A, group B, and group C, respectively. In group A, the odds ratio and risk ratio were 19-fold and 5-fold, respectively, for the HSP70 hom T/T homozygous gene compared to B (OR 19.45; RR 5.42; X2 38.8, p < 0.0001). Moreover, 4-fold and 1.75-fold ratios have been compared with group C (OR 4.03; RR 1.72; X2 10.6, p < 0.001). No significant difference in genotype was observed in group B and group C. Conclusions: There is a significant and positive association of hspHSP70 hom polymorphism restricted to T allele in homozygous and heterozygous states among diabetic foot ulcer (DFU) patients.
