Song W, La Fontaine J, Shibuya N, Prochaska J, Jupiter DC. The Effect of Limb Salvage Efforts in Different Age Groups: Relationships Between Major and Minor Amputations. J Foot Ankle Surg 2024; 63:380-385. [PMID: 38266807 DOI: 10.1053/j.jfas.2024.01.010] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 09/14/2023] [Revised: 11/14/2023] [Accepted: 01/15/2024] [Indexed: 01/26/2024]
Abstract
"Limb salvage" efforts, such as performing minor amputations before infections spread proximally from the foot to decrease major lower extremity amputation, are an important part of healthcare today. It is unclear whether these efforts are preventing the number of major amputations and improving patients' quality of life and the cost-effectiveness of the U.S. healthcare system. Rates of non-traumatic lower extremity amputation (NLEA) among patients with diabetes decreased in the early 2000s but rebounded in the 2010s. We analyzed the proportion of major amputations and differences in amputation rates between age groups in Texas. Patient data was extracted from the Texas Hospital Discharge Data Public Use Data File. Population estimates were obtained from the Texas Population Estimates Program from 2011 to 2015 and from intercensal estimates provided by the U.S. Census Bureau from 2006 to 2010. Raw numbers of minor, major, and all NLEA surgeries and the ratio of major amputations to total amputations per year were reported for each age group. Poisson regression and Joinpoint analyses were performed to capture these changes in trends. Rates of amputations increased, with significant decreasing relative prevalence of major amputations. Patients aged 45 to 64 with diabetes are likely driving these increases. Rates of lower extremity amputation in patients with diabetes increased from 2009 to 2015. This holds for all and minor amputations. In contrast, the ratio of major to all amputations decreased from 2010. Utilization of major and minor amputation differs between age groups, remaining stable in the youngest subjects, with minor amputation rates increasing in those aged 45 to 64.

PLoS One 2023; 18:e0293872. [PMID: 37922259 PMCID: PMC10624312 DOI: 10.1371/journal.pone.0293872] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/19/2022] [Accepted: 10/20/2023] [Indexed: 11/05/2023] Open
Abstract
BACKGROUND Research has shown that insulin resistance (IR) is a known risk factor for diabetic foot (DF), and the triglyceride-glucose (TyG) index is a reliable and simple indicator of IR. However, less is known about the relationship between the TyG and the risk of DF. Here, we investigated the association between the TyG index and the prevalence of DF. METHODS The eligible records from the Departments of Endocrinology of Shandong Provincial Hospital Affiliated to Shandong First Medical University were screened (from December 1, 2012, to December 31, 2021), and a total of 8866 patients were enrolled. The TyG index was calculated as ln[(fasting triglycerides (mg/dL)×fasting glucose (mg/dL)/2)]. The continuous variables between the DF and the non-DF groups were compared by Student's t test or the Mann-Whitney U test, and categorical variables were compared by the chi-square test. Receiver operating characteristic curve (ROC) analysis was carried out to estimate the predictive value of the TyG index for DF. Logistic regression models were used to evaluate the associations between the quartiles of the TyG index and the risk of DF. Subgroup and sensitivity analyses were conducted. RESULTS The TyG index was significantly lower in the DF group than in the no-DF group. The logistic regression revealed that an increased TyG index was associated with a lower risk of DF after adjusting for potential confounders. In addition, an ROC analysis indicated the discriminatory ability of the TyG index in DF presence with an area under the curve (AUC) of 0.661 (95% CI 0.642-0.680, P < 0.001). Subgroup and sensitivity analysis also supported these robust results. CONCLUSIONS The TyG index was inversely and dose-dependently associated with the risk of DF in diabetes patients, indicating that elevated TyG index was a protective factor for DF. Future studies are therefore warranted to confirm our finding and to explore the detailed pathological mechanism involved in this process.

Abstract
The term 'diabetic foot disease' (DFD) often signifies the presence of foot ulceration and infection, but one must also be wary of the rarer occurrence of Charcot foot disease. The worldwide prevalence of DFD is 6.3% (95%CI: 5.4-7.3%). Foot complications present a major challenge to both patients and healthcare systems, with increased rates of hospitalisation and an almost trebled 5-year mortality. The Charcot foot often occurs in patients with long-standing diabetes, presenting as an inflamed or swollen foot or ankle, following unrecognised minor trauma. This review focuses on the prevention and early identification of the 'at-risk' foot. DFD is best managed by a multi-disciplinary foot clinic team consisting of podiatrists and healthcare professionals. This ensures a combination of expertise and provision of a multi-faceted evidence-based treatment plan. Current research using endothelial progenitor cells (EPC) and mesenchymal stem cells (MSC) offers a new dimension in wound management.

Abstract
BACKGROUND Diabetic foot assessments detect patients at risk for developing a diabetes-related foot ulceration and can significantly reduce the risk of amputation. In order to organize this assessment effectively, diabetic foot assessment guidelines are required according to the International Working Group of the Diabetic Foot. However, these international guidelines have not been adapted into a national guideline for podiatrists in Flanders, Belgium. This study aims to identify the methods and guidelines currently used to assess the diabetic foot in private podiatry practices in Flanders, Belgium and to explore the podiatrists' opinions on developing a national diabetic foot assessment guideline. METHODS This exploratory mixed method study was composed of an anonymous online survey comprising of open- and closed-ended questions followed by 1:1 online semi-structured interviews. Participants were recruited via e-mail and a closed private Facebook group of podiatry alumni. Data was analyzed using SPSS statistics and thematic analysis described by Braun and Clarke. RESULTS This study showed that the vascular assessment of the diabetic foot exists solely of a medical history and palpation of the pedal pulses. Non-invasive tests such as doppler, toe brachial pressure index or ankle brachial pressure index are seldom used. Only 66% reported to use a guideline for the diabetic foot assessment. There was a variety of reported guidelines and risk stratification systems in use in private podiatry practices in Flanders, Belgium. CONCLUSION Non-invasive tests such as the doppler, ankle brachial pressure index or toe brachial pressure index are rarely used for the vascular assessment of the diabetic foot. Diabetic foot assessment guidelines and risk stratification systems to identify patients at risk for developing a diabetic foot ulcer were not frequently used. International guidelines of the International Working Group of the Diabetic Foot have not yet been implemented in private podiatry practices in Flanders, Belgium. This exploratory research has provided useful information for future research studies.

Abstract
OBJECTIVE The establishment of multidisciplinary foot team clinics reduces the risk of amputation, but little is known about its resource requirement. This study evaluates the service's resource use for first visit attendees to an established multidisciplinary foot team clinic. METHOD A retrospective evaluation was performed for new referrals to the clinic over six months, including demographics, resource use and clinical outcome. Data were extracted electronically with retrospective review of electronic clinical notes. RESULTS A total of 240 first visit attendees were analysed. Mean age was 64±15years, 63% were male, 72% had type 2 diabetes, 16% had type 1 diabetes, 15% had a previous amputation, and 40% had a previous ulceration. Common presentations were ulcers (62%), osteomyelitis (11%), Charcot foot (19%), foot ischaemia (17%), post-surgical wounds (13%), and osteomyelitis (11%). At first attendance, 79% of patients required specialist services including diabetologist (45%), joint vascular review (23%), joint orthopaedics services (8%), dermatologist (2%), and orthotics services (1%). A total of 4% of patients had complex debridement, 0.4% total nail excision, 0.8% pus drainage, 3% cast-related procedures, and 1% vacuum-assisted dressing. Of the patients, 4% were admitted to hospital, 38% had vascular duplex investigations, 7% had a deep vein thrombosis scan, 16% had magnetic resonance imagine (MRI), and 5% had a bone scan. CONCLUSION A functional multidisciplinary foot team clinic requires significant resources-both clinical and administrative-for prompt investigations and revascularisation to sustain low amputation rates. Regular appraisal of resource use helps with clinic and pathway planning.

Abstract
BACKGROUND AND AIMS The study aimed at determining prevalence and risk factors (RFs) of diabetic lower limb amputations (LLAs). METHODS Electronic databases including PubMed, Medline, Web of Science, and Cochrane Library were searched from January 2003 to April 2021. RESULTS Sixteen full-text published studies were reviewed. The prevalence of LLAs stood as high as 66%, with a combined prevalence of 19% (95% CI 10-29) using the random-effects model. The most prominent RFs for LLA were duration of diabetes mellitus (DM), age, renal impairment, and ethnic minority. Amongst Australians, Indigenous background is strongly associated with increased risk of the diabetic foot (DF) LLA. CONCLUSIONS LLAs are considerably prevalent amongst patients with the DF and occur at even higher rates in patients with multimorbidity.

Abstract
Aim: To determine the prevalence of foot morbidity among patients with ESRD on dialysis. Methods: A prospective, non-experimental, quantitative time series design was employed. Forty-seven participants were recruited in the study. Medical records were reviewed followed by non-invasive foot assessments which included: Neurological, Arterial, Biomechanical, and Dermatological Assessment. Participants were assessed twice during the study. Results: Foot morbidity was found to be high among participants with ESRD on dialysis. 95.74% of participants presented with foot deformities, 76.60% had skin and nail conditions. 15% of participants had a history of ulceration and amputation. Moreover, active ulceration and history of revascularisation were also observed. Findings demonstrated overall poor foot health and footcare behavior within this population with 40.43% of participants having inappropriate footwear. The majority of participants did not check feet regularly, did not attend to podiatry appointments, and were unable to reach their feet for self-care. The Toe Brachial Pressure Index (TBPI), Spectral Doppler Waveform Analysis, and the Quantitative Sensory Testing (QST) were re-measured at each visit. Monophasic continuous doppler waveforms increased while triphasic waveforms decreased during the study period. Protective sensation did not decrease during the study period. The mean TBPI decreased during the study period. The relationship between the TBPI and duration of dialysis was found to be significant. Both DM and dialysis duration were identified as significant predictors of reduction in TBPI. Conclusion: This study demonstrates a high prevalence of foot morbidity among patients with ESRD on dialysis. This study highlighted the importance of expanding practice by introducing a podiatry service within the renal unit to provide foot screening, foot assessments, and foot care education, with the aim to reduce severe foot complications.

Abstract
BACKGROUND Diabetic foot ulcer (DFU) is a serious chronic complication of diabetes. This study aimed to establish weighted risk models for determining DFU occurrence and severity in diabetic patients. METHODS This was a multi-center hospital-based cross-sectional study. A total of 1488 diabetic patients with or without an ulcer from three tertiary hospitals were included in the study. Random forest method was used to develop weighted risk models for assessing DFU risk and severity. Receiver operating characteristic curves were used to validate the models and calculate the optimal cut-off values of the important risk factors. RESULTS We developed potent weighted risk models for evaluating DFU occurrence and severity. The top eight important risk factors for DFU onset were plasma fibrinogen, neutrophil percentage and hemoglobin levels in whole blood, stroke, estimated glomerular filtration rate, age, duration of diabetes, and serum albumin levels. The top 10 important risk factors for DFU severity were serum albumin, neutrophil percentage and hemoglobin levels in whole blood, plasma fibrinogen, hemoglobin A1c, estimated glomerular filtration rate, hypertension, serum uric acid, diabetic retinopathy, and sex. Furthermore, the area under curve values in the models using plasma fibrinogen as a single risk factor for determining DFU risk and severity were 0.86 (sensitivity 0.74, specificity 0.87) and 0.73 (sensitivity 0.76, specificity 0.58), respectively. The optimal cut-off values of plasma fibrinogen for determining DFU risk and severity were 3.88 g/L and 4.74 g/L, respectively. CONCLUSIONS We have established potent weighted risk models for DFU onset and severity, based on which precise prevention strategies can be formulated. Modification of important risk factors may help reduce the incidence and progression of DFUs in diabetic patients.

Abstract
PURPOSE The purpose of this study was to investigate the risk factors for major amputation in persons hospitalized with diabetic foot ulcers involving the midfoot. DESIGN Retrospective study. SUBJECTS AND SETTING Between January 2003 and May 2019, a total of 1931 patients with diabetes were admitted to the diabetic wound center for the management of foot ulcers. Among the admitted patients, 169 patients with midfoot ulcers were included in this study. One hundred fifty-four patients (91%) healed without major amputation, while 15 patients (9%) healed post-major amputation. METHODS Data related to 88 potential risk factors including demographics, ulcer condition, vascularity, bioburden, neurology, and serology were collected from patients in these 2 groups for comparison. Univariate and multivariate logistic regression analyses were performed to analyze risk factors for major amputation. RESULTS Among the 88 potential risk factors, 15 showed statistically significant differences between the 2 groups. Using univariate analysis of 88 potential risk factors, 8 showed statistically significant differences. Using stepwise multiple logistic regression analysis, 3 of the 8 risk factors remained statistically significant. Multivariate-adjusted odds ratios for deep ulcers invading bone, cardiac disorders, and Charcot foot were 26.718, 18.739, and 16.997, respectively. CONCLUSION The risk factors for major amputation in patients hospitalized with diabetic midfoot ulcers included deep ulcers invading the bone, cardiac disorders, and Charcot foot.

Abstract
OBJECTIVE We explored barriers to proper foot care in this population using a qualitative approach with focus group discussions (FGD). METHODS Participants were recruited from clinics at a safety-net hospital in Atlanta, Georgia and stratified into two groups: diabetic foot ulcer (DFU) and minor amputation (below ankle). The FGDs addressed patient experience in receiving care with a goal of understanding: foot care knowledge, barriers to care, and preferred educational methods. Surveys were performed to supplement FGDs. RESULTS Forty participants (90% Black) were enrolled. Dominant themes emerging from FGDs were: 1-Patients reported adequate understanding of recommended foot care practices; 2-Personal barriers to self-care included lack of motivation, high cost, poor insurance coverage of supplies, and difficulty limiting activity for proper offloading; 3-Hospital system barriers included difficulty making timely appointments and reaching a provider to arrange care; 4-Access to footcare-related information and services improved with greater disease severity. Participants stressed that improved access often came too late to alter their course. They expressed interest in developing peer support groups to facilitate learning and sharing information relating to DFU. CONCLUSION We found that patients with DFU or minor amputations have adequate footcare-related knowledge, but personal and systemic barriers limited appropriate foot care.

Abstract
OBJECTIVE To explore the role and mechanism of oxidative stress injury in the diabetic foot. METHODS Immunohistochemistry and staining were used to detect changes in diabetic foot tissue, and the CCK-8 method was used to measure high glucose effect on cell viability. The DCFH-DA assay was used to detect the intracellular ROS content, and colorimetric methods were used to detect the activities of the CAT and SOD enzymes and the NO and MDA content in tissues and cells. In addition, the protein expression levels of PKCβ, p66shc, eNOS, ICAM-1 and NF-κB in tissues and cells were detected by Western blotting, and the distribution of p66shc and eNOS was observed by immunofluorescence. RESULTS The results of clinical specimens experiments showed that the DFU group exhibited disordered morphology and increased glucose metabolism, decreased activities of the enzymes CAT and SOD in tissues, and increased MDA and NO contents compared to those in the CON group. Furthermore, protein levels of the p-PKCβ, p-p66shc, ICAM-1, and p-NF-κB were increased, and eNOS protein level was decreased; these results were consistent in clinical specimens and in vitro experiments. CONCLUSIONS High glucose levels may induce oxidative stress injury in cells and tissues by activating the PKCβ-p66shc signaling pathway.

National and State-Level Trends in Nontraumatic Lower-Extremity Amputation Among U.S. Medicare Beneficiaries With Diabetes, 2000-2017. Diabetes Care 2020; 43:2453-2459. [PMID: 32723844 PMCID: PMC10982954 DOI: 10.2337/dc20-0586] [Citation(s) in RCA: 40] [Impact Index Per Article: 10.0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 03/20/2020] [Accepted: 07/07/2020] [Indexed: 02/03/2023]
Abstract
OBJECTIVE Diabetes is a leading cause of nontraumatic lower-extremity amputation (NLEA) in the U.S. After a period of decline, some national U.S. data have shown that diabetes-related NLEAs have recently increased, particularly among young and middle-aged adults. However, the trend for older adults is less clear. RESEARCH DESIGN AND METHODS To examine NLEA trends among older adults with diabetes (≥67 years), we used 100% Medicare claims for beneficiaries enrolled in Parts A and B, also known as fee for service (FFS). NLEA was defined as the highest-level amputation per patient per calendar year. Annual NLEA rates were estimated from 2000 to 2017 and stratified by age-group, sex, race/ethnicity, NLEA level (toe, foot, below-the-knee amputation [BKA], or above-the-knee amputation [AKA]), and state. All rates were age and sex standardized to the 2000 Medicare population. Trends over time were assessed using Joinpoint regression and annual percent change (APC) reported. RESULTS NLEA rates (per 1,000 people with diabetes) decreased by half from 8.5 in 2000 to 4.4 in 2009 (APC -7.9, P < 0.001). However, from 2009 onward, NLEA rates increased to 4.8 (APC 1.2, P < 0.01). Trends were similar across most age, sex, and race/ethnic groups, but absolute rates were highest in the oldest age-groups, Blacks, and men. By NLEA type, overall increases were driven by increases in rates of toe and foot NLEAs, while BKA and AKA continued to decline. The majority of U.S. states showed recent increases in NLEA, similar to national estimates. CONCLUSIONS This study of the U.S. Medicare FFS population shows that recent increases in diabetes-related NLEAs are also occurring in older populations but at a less severe rate than among younger adults (<65 years) in the general population. Preventive foot care has been shown to reduce rates of NLEA among adults with diabetes, and the findings of the study suggest that those with diabetes-across the age spectrum-could benefit from increased attention to this strategy.

BMC Med Inform Decis Mak 2020; 20:200. [PMID: 32838777 PMCID: PMC7446175 DOI: 10.1186/s12911-020-01195-x] [Citation(s) in RCA: 4] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/27/2020] [Accepted: 07/20/2020] [Indexed: 01/06/2023] Open
Abstract
Background Diabetes mellitus is a major global health issue with a growing prevalence. In this context, the number of diabetic complications is also on the rise, such as diabetic foot ulcers (DFU), which are closely linked to the risk of lower extremity amputation (LEA). Statistical prediction tools may support clinicians to initiate early tertiary LEA prevention for DFU patients. Thus, we designed Bayesian prediction models, as they produce transparent decision rules, quantify uncertainty intuitively and acknowledge prior available scientific knowledge. Method A logistic regression using observational collected according to the standardised PEDIS classification was utilised to compute the six-month amputation risk of DFU patients for two types of LEA: 1.) any-amputation and 2.) major-amputation. Being able to incorporate information which is available before the analysis, the Bayesian models were fitted following a twofold strategy. First, the designed prediction models waive the available information and, second, we incorporated the a priori available scientific knowledge into our models. Then, we evaluated each model with respect to the effect of the predictors and validity of the models. Next, we compared the performance of both models with respect to the incorporation of prior knowledge. Results This study included 237 patients. The mean age was 65.9 (SD 12.3), and 83.5% were male. Concerning the outcome, 31.6% underwent any- and 12.2% underwent a major-amputation procedure. The risk factors of perfusion, ulcer extent and depth revealed an impact on the outcomes, whereas the infection status and sensation did not. The major-amputation model using prior information outperformed the uninformed counterpart (AUC 0.765 vs AUC 0.790, Cohen’s d 2.21). In contrast, the models predicting any-amputation performed similarly (0.793 vs 0.790, Cohen’s d 0.22). Conclusions Both of the Bayesian amputation risk models showed acceptable prognostic values, and the major-amputation model benefitted from incorporating a priori information from a previous study. Thus, PEDIS serves as a valid foundation for a clinical decision support tool for the prediction of the amputation risk in DFU patients. Furthermore, we demonstrated the use of the available prior scientific information within a Bayesian framework to establish chains of knowledge.

Abstract
AIM The aim of this study was to investigate the factors involved in healing failure in a population of patients with diabetic foot ulcers (DFU) after one year of follow-up. METHODS One hundred and forty-four patients were treated for DFU in a tertiary-care center and had a regular follow-up for one year. Laboratory measurements and clinical assessments, including long-term diabetes complications and risk factors for DFU, were collected at baseline and patients were divided in two groups according to the outcome [Healed group (H, n = 91), and Not Healed group (NH, n = 53)]. RESULTS Compared with H group, NH group had significant higher levels of urinary albumin excretion [H vs NH, median (IQR), 23.5 (10.1, 41.1) vs 26.4 (20.8, 141.1), P = 0.032] and significantly increased prevalence of diabetic kidney disease (DKD) (22% vs 40%, P = 0.038) and Charcot Arthropathy (3% vs 16%, P = 0.025). No differences among the other long-term complications of diabetes, risk factors for DFU or clinical features were found. The multiple logistic regression analysis identified DKD and Charcot Arthropathy as negative predictors of healing. CONCLUSIONS In a population of people with type 2 diabetes with DFU treated in a tertiary-care center, DKD and Charcot Arthropathy were related to poor healing within one year-follow-up.

Abstract
Percutaneous flexor tenotomy is a minimally invasive procedure that involves cutting one or both flexor digitorum tendons underneath the toe. It is an alternative to open surgical procedures performed in an operating theatre. This project is a prospective case series investigating the utility, effectiveness, and participant satisfaction of the percutaneous flexor tenotomy when performed in the outpatient setting. People with diabetes, digital flexion deformity, and loss of protective sensation with an apical ulcer or preulcerative lesion presenting to the Austin Health Foot Ulcer Specialist Outpatient Clinic were enrolled in the study. The procedure was performed under sterile technique with an 18-gauge needle or fine scalpel blade. Participants were reviewed weekly until the incision and/ or ulcer healed. Participants were then followed up at 3 and 6 months. Time to ulcer healing, reulceration rate, frequency of complications, and patient satisfaction were recorded. There were 11 toe ulcers and 41 preulcerative lesions. A total of 76 tenotomy procedures were performed on the 23 participants across 35 episodes of care. The mean time to ulcer healing following tenotomy was 10.2 ± 4.3 days. There were no recurrences of ulceration. The infection rate per episode of care was 2.8%. There were 11 toes (14.5%) that sustained a transfer lesion post the index procedure. The mean time to development of a transfer lesion was 95.5 ± 98.1 days. All participants strongly agreed that they were satisfied with the outcome of the procedure. The flexor tenotomy is an effective procedure to expedite the healing of apical toe ulcers in people with loss of protective sensation and flexion digital deformity. It has a low infection rate and high patient satisfaction rate when performed in the outpatient setting. There is a moderate risk of transfer preulcerative lesions to an adjacent digit. Levels of Evidence: Level IV: Prospective case series.

A position statement from the Italian diabetic foot study group. Nutr Metab Cardiovasc Dis 2020; 30:167-178.

Abstract
Diabetic foot syndrome (DFS) is a complex disease. The best outcomes are reported with the multi-disciplinary team (MDT) approach, where each member works collaboratively according to his/her expertise. However, which health provider should act as the team leader (TL) has not been determined. The TL should be familiar with the management of diabetes, related complications and comorbidities. He/she should be able to diagnose and manage foot infections, including prompt surgical treatment of local lesions, such as abscesses or phlegmons, in an emergent way in the first meeting with the patient. According to the Organization for Economic Co-operation and Development (OECD) reports, Italy is one of countries with a low amputation rate in diabetic patients. Many factors might have contributed to this result, including 1)the special attention directed to diabetes by the public health system, which has defined diabetes as a "protected disease", and accordingly, offers diabetic patients, at no charge, the best specialist care, including specific devices, and 2)the presence of a network of diabetic foot (DF) clinics managed by diabetologists with medical and surgical expertise. The health care providers all share a "patient centred model" of care, for which they use their internal medicine background and skills in podiatric surgery to manage acute or chronic needs in a timely manner. Therefore, according to Italian experiences, which are fully reported in this document, we believe that only a skilled diabetologist/endocrinologist should act as a TL. Courses and university master's degree programmes focused on DF should guarantee specific training for physicians to become a TL.

Abstract
Diabetic patients frequently develop chronic ulcers of the lower extremities, which are a frequent cause for hospitalization and amputation, placing strain on patients, their families, and healthcare systems. Present therapies remain a challenge, with high recurrence rates. Photobiomodulation (PBM), which is the non-invasive application of light at specific wavelengths, has been shown to speed up healing of chronic wounds, including diabetic foot ulcers (DFUs). PBM produces photophysical and photochemical changes within cells without eliciting thermal damage. It has been shown to promote tissue regeneration and speed up wound repair by reducing inflammation and oxidative stress, accelerating cell migration and proliferation, and promoting extracellular matrix production and release of essential growth factors. The shortage of rigorous, well-designed clinical trials makes it challenging to assess the scientific impact of PBM on DFUs, and lack of understanding of the underlying mechanisms also hinders the conventional use of this therapy. This review gives a glimpse into diabetic wound healing and PBM, and the effects of PBM on diabetic wound healing.

Abstract
OBJECTIVE Nontraumatic lower-extremity amputation (NLEA) is a complication of end-stage renal disease (ESRD) and diabetes. Although recent data show that NLEA rates in the U.S. ESRD population are declining overall, trends in diabetes and diabetes subgroups remain unclear. RESEARCH DESIGN AND METHODS We estimated annual rates of NLEA hospitalizations during 2000-2015 among >2 million adults (≥18 years) with ESRD from the U.S. Renal Data System. Age, sex, and race-adjusted NLEA rates were stratified by diabetes status, age, sex, race, and level of amputation (toe, foot, below the knee, and above the knee). Time trends were assessed using Joinpoint regression with annual percent changes (APC) reported. RESULTS Among adults with diabetes, NLEA rates declined 43.8% between 2000 and 2013 (from 7.5 to 4.2 per 100 person-years; APC -4.9, P < 0.001) and then stabilized. Among adults without diabetes, rates of total NLEAs declined 25.5% between 2000 and 2013 (from 1.6 to 1.1; APC -3.0, P < 0.001) and then stabilized. These trends appear to be driven by a slowing or stagnation in declines of minor NLEAs (toe and foot) in more recent years, while major NLEAs (above the knee) continue to decline. CONCLUSIONS Despite an initial period of decline, this analysis documents a stall in progress in NLEA trends in recent years in a high-risk population with both ESRD and diabetes. Increased attention to preventive foot care in the ESRD population should be considered, particularly for those with diabetes.

Abstract
INTRODUCTION According to the American Diabetes Association (ADA), patients with diabetes should receive annual foot exams from a HCP to identify and reduce risk factors for ulcers and other complications. Little is known regarding factors that may increase or decrease the likelihood of having an annual foot examination by a health care provider (HCP). METHODS Cross-sectional analysis of 1830 patients age 20 years and older with a previous diagnosis of diabetes. Patients selected for inclusion in NHANES receive an in-home interview and then undergo a comprehensive physical at a CDC mobile examination center. The adjusted odds ratios for a patient having received a foot exam from a HCP in the past year were conducted using appropriate weighting variables assessed with logistic regression analysis. RESULTS Both Hispanic Americans with diabetes [aOR 0.62 (0.47, 0.82)] and Asian Americans with diabetes [aOR 0.65 (0.44, 0.97)] were significantly less likely to have had a foot exam by a HCP in the last year, when compared to non-Hispanic White Americans. CONCLUSIONS Hispanic Americans and Asian Americans with diabetes were significantly less likely to have had a foot exam by a HCP in the last year.

Abstract
Introduction The major grave outcome of diabetic complications is the amputation of lower limb extremities. Recurrent foot infections, trauma, ischemia, and peripheral neuropathy play a crucial role in predicting foot amputation. The aim of this study is to identify the risk factors of diabetic foot amputations in Pakistani patients. Methods Patients admitted with diabetic foot-related complications were followed throughout their hospital stay. Their sociodemographic and disease-related characteristics were recorded. Patients who were advised foot amputation were taken as group A, and patients who were managed conservatively were termed as group B. Their characteristics were then compared. Results Out of 226 study participants, there were 51 (22.5%) patients in group A who were advised foot amputation. There were more men in group A as compared to group B (72.5% vs. 30.8%; p<0.00001). Group A also had a longer duration of diabetes (15.23 ± 8.52 years vs. 11.98 ± 9.69; p=0.03). Group B included more patients taking insulin therapy (44.5% vs. 37.3%; p=0.002). All three risk factors of atherosclerosis - smoking, hyperlipidemia, and hypertension - were significantly associated with group A (p≤0.05). This coexistence of diabetic nephropathy and retinopathy were more common in group A (p≤0.05). Conclusion The incidence of foot amputation in diabetic patients is high. Crucial risk factors include male gender, smoking, hyperlipidemia, hypertension, cardiac history, and the coexistence of diabetic nephropathy and retinopathy.

Abstract
Objective: The purpose of this study was to investigate the risk factors for major amputation in patients hospitalized with diabetic foot ulcers involving the hindfoot. Approach: Between January 2003 and October 2017, a total of 1,657 diabetic patients were admitted to the diabetic wound center of Korea University Guro Hospital, for the management of foot ulcers. Among the admitted patients, 117 diabetic patients with hindfoot ulcers were included in this study. One hundred and four patients (89%) healed without major amputation, while 13 patients (11%) healed with major amputation. Data related to 88 potential risk factors, including demographics, ulcer condition, vascularity, bioburden, neurology, and serology, were collected from patients in these two groups for comparison. Results: Among the 88 potential risk factors, 15 showed statistically significant differences between the two groups. In univariate analysis of 88 potential risk factors, nine showed statistically significant differences. In stepwise multiple logistic regression analysis, three of the nine risk factors remained statistically significant. Multivariate-adjusted odds ratios for pulmonary disorders, erythrocyte sedimentation rate (ESR) levels, and total iron-binding capacity (TIBC) levels were 38.525, 1.047, and 0.976, respectively. Innovation: Compared with forefoot and midfoot ulcers, diabetic foot ulcers involving the hindfoot are at increased risk of major amputation because infection may spread proximal to the ankle. However, large-scale cohort studies that specifically discuss the outcomes and characteristics of diabetic hindfoot ulcers are not widely available. Conclusion: Risk factors for major amputation in patients hospitalized with diabetic hindfoot ulcers include pulmonary disorders, high levels of ESR, and decreased TIBC levels.

Abstract
Diabetic foot ulceration (DFU) is a common and debilitating complication of diabetes that is preventable through active engagement in appropriate foot-related behaviours, yet many individuals with diabetes do not adhere to foot care recommendations. The aim of this paper was to synthesise the findings of qualitative papers exploring diabetic people's perceptions and experiences of DFU in order to identify how they could be better supported to prevent ulceration or manage its impact. Five databases (MEDLINE, PsycINFO, CINAHL, EMBASE, Web of Science) were searched in May 2016 to identify eligible articles. Findings were synthesised using a meta-ethnographic approach. Forty-two articles were eligible for inclusion. Synthesis resulted in the development of five overarching themes: personal understandings of diabetic foot ulceration; preventing diabetic foot ulceration: knowledge, attitudes, and behaviours; views on health care experiences; development of diabetic foot ulceration and actions taken; and wide-ranging impacts of diabetic foot ulceration. The findings highlight various barriers and facilitators of foot care experienced by people with diabetes and demonstrate the significant consequences of ulcers for their physical, social, and psychological well-being. The insights provided could inform the development of interventions to promote foot care effectively and provide appropriate support to those living with ulceration.

Abstract
BACKGROUND Diabetes is a major chronic disease with high morbidity and mortality. Diabetic preventive care services are essential in the management and outcome of the disease. More than other preventive diabetic care services, preventive care of diabetic retinopathy has been emphasized and recommended by practitioners and insurance companies. We investigated the status of preventive care in the diabetic population. METHODS Information was collected from 420 outpatients aged 30 to 80 years. The patients were divided into two groups: those with well-controlled blood sugar levels (hemoglobin A1c [HbA1c] level ≤7%) and those with uncontrolled blood sugar levels (HbA1c level >7%). RESULTS Data analysis indicated that for both groups, 93% of the participants were seen for diabetic eye care at least once and 78% were getting an annual eye examination regularly. In the controlled and uncontrolled blood sugar groups, 26% and 32% of patients, respectively, had ever seen a nephrologist and 38% and 49%, respectively, had ever seen a cardiologist. In the controlled and uncontrolled blood sugar groups, 32% and 38% of patients, respectively, had visited a podiatric physician. For statistical analysis and comparison of results between the two groups, we applied the χ2 test and calculated 95% confidence intervals. There were some significant differences regarding the complications of diabetes mellitus and preventive care. CONCLUSIONS There is a need for greater engagement by podiatric physicians and health-care providers to promote regular visits for the diabetic population to podiatric medical clinics.

Abstract
Diabetic foot ulcers remain a major health care problem. They are common, result in considerable suffering, frequently recur, and are associated with high mortality, as well as considerable health care costs. While national and international guidance exists, the evidence base for much of routine clinical care is thin. It follows that many aspects of the structure and delivery of care are susceptible to the beliefs and opinion of individuals. It is probable that this contributes to the geographic variation in outcome that has been documented in a number of countries. This article considers these issues in depth and emphasizes the urgent need to improve the design and conduct of clinical trials in this field, as well as to undertake systematic comparison of the results of routine care in different health economies. There is strong suggestive evidence to indicate that appropriate changes in the relevant care pathways can result in a prompt improvement in clinical outcomes.

Abstract
BACKGROUND Dialysis therapy is associated with an increased incidence of lower-extremity wounds and amputations. We compared the incidence of foot ulcers and amputations before and after the start of dialysis. METHODS We evaluated 150 consecutive diabetic patients receiving dialysis and compared the incidence of foot complications 30 months before and after initiation of hemodialysis. We used claims data for diabetes, ulceration, and dialysis and abstracted medical records to verify diagnoses and dates of ulcers and amputations. We compared initial and cumulative ulcer/amputation incidence to account for multiple events in the same person over time. We used the same formula to determine the incidence rate difference and 95% confidence intervals (CIs) to compare new ulcers and amputations during the study. RESULTS There was no significant difference in the incidence of first foot ulcers before (91.7 per 1,000 patient-years; 95% CI, 73.7-112.3 per 1,000 patient-years) and after (82.7; 95% CI, 65.7-102.3) the start of hemodialysis. The incidence of cumulative ulcers was significantly higher before (304.0 per 1,000 patient-years; 95% CI, 270.8-340.2) compared with after (210.7 per 1,000 patient-years; 95% CI, 183.0-240.9) dialysis. There was no difference in the incidence of first amputation before (29.3 per 1,000 patient-years; 95% CI, 1 9.4-41.7 per 1,000 patient-years) and after (37.3 per 1,000 patient-years; 95% CI, 19.4-41.7 per 1,000 patient-years) dialysis or in the cumulative incidence of amputations before (61.3 per 1,000 patient-years; 95% CI, 46.7-8.4 per 1,000 patient-years) and after (58.7 per 1,000 patient-years; 95% CI, 44.5-75.5 per 1,000 patient-years) dialysis. CONCLUSIONS There was no increase in the incidence of ulcers or amputations after beginning hemodialysis.

Abstract
Diabetic foot disease heavily weighs upon diabetics, being a significant cause of morbidity and severe disability. Their prevention is indispensable. Our study aimed to reduce the rate of amputations in diabetics. We conducted a retrospective, descriptive, cross-sectional, multicenter study of podiatric risk screening in patients with type 2 diabetes in the Endocrinology Department at the University Hospital of Befelatanana and at the Amadia Clinic, Faravohitra, over a period of 6 months. The average age of our patients was 54.43 years. Male sex predominated (60%). The patients suffered from diabetes which had evolved, on average, over a period of 7.35 years. The most common patient's history was smoking and chronic ulcerations of the foot. More than half of patients had an imbalance of diabetes, microalbuminuria and retinopathy. 56.50% of patients were aware of their risk but less than 46% of patients gave specific examples of appropriate behaviour. Only 13.33% of patients had undergone foot examination before this study. Their podiatric risk was very high. Predictive factors for ulceration included smoking, a history of chronic ulcer of the lower limbs, an imbalance of diabetes and foot deformity. Effective prevention strategies for amputations should include the screening and the identification of population at risk of ulceration.

Abstract
BACKGROUND The Amputation Prevention Initiative is a project conducted jointly by the Massachusetts Public Health Association and the Massachusetts Podiatric Medical Society that seeks to study methods to reduce nontraumatic lower-extremity amputations from diabetes. METHODS To determine the rate of diabetes-related lower-extremity amputations in Massachusetts and identify the groups most at risk, hospital billing and discharge data were analyzed. To examine the components of the diabetic foot examination routinely performed by general practitioners, surveys were conducted in conjunction with physician meetings in Massachusetts (n = 149) and in six other states (n = 490). RESULTS The average age-adjusted number of diabetes-related lower-extremity amputations in 2004 was 30.8 per 100,000 and 5.3 per 1,000 diabetic patients in MA, with high-risk groups being identified as men and black individuals. Among the general practitioners surveyed in Massachusetts, only 2.01% reported routinely conducting all four key components of the diabetic foot examination, with 28.86% reporting not performing any components. CONCLUSIONS These findings suggest that many general practitioners may be failing to perform the major components of the diabetic foot examination believed to prevent foot ulcers and lower-extremity amputations.

Abstract
Abstract Introduction: Diabetes Mellitus is a chronic disease with high prevalence in the population in particular among the elderly. The longer time of diabetes, increased the chances of developing complications such as peripheral neuropathy, which is an important factor in the genesis of plantar lesions by changing the distribution and formation of plantar pressure peaks. Objective: Evaluate the influence of an Assistive Technology, therapeutic footwear for diabetics, in the peaks of plantar pressure of elderly. Methods: This was an experimental study of transversal type, composed by 10 elderly, diabetic, with peripheral neuropathy, using as an instrument to measure a baropodometry platform. Were measured peaks of plantar pressure, static and dynamic in three situations: barefoot, the participants' own standard footwear and with therapeutic footwear for diabetics. Data analysis by normal distribution as a single paired sample, applying the ANOVA test. Results: The use of therapeutic footwear for diabetics promoted a reduction in media of peak plantar pressure in the order of 22% in static analysis, and 31% in dynamic analysis. Conclusion: The therapeutic footwear for diabetics was able to produce significant reductions in peak plantar pressure, being more efficient than a common footwear. This effect may contribute to the prevention of injuries associated with the diabetic foot.

Abstract
Diabetic foot ulceration poses a heavy burden on the patient and the healthcare system, but prevention thereof receives little attention. For every euro spent on ulcer prevention, ten are spent on ulcer healing, and for every randomized controlled trial conducted on prevention, ten are conducted on healing. In this article, we argue that a shift in priorities is needed. For the prevention of a first foot ulcer, we need more insight into the effect of interventions and practices already applied globally in many settings. This requires systematic recording of interventions and outcomes, and well-designed randomized controlled trials that include analysis of cost-effectiveness. After healing of a foot ulcer, the risk of recurrence is high. For the prevention of a recurrent foot ulcer, home monitoring of foot temperature, pressure-relieving therapeutic footwear, and certain surgical interventions prove to be effective. The median effect size found in a total of 23 studies on these interventions is large, over 60%, and further increases when patients are adherent to treatment. These interventions should be investigated for efficacy as a state-of-the-art integrated foot care approach, where attempts are made to assure treatment adherence. Effect sizes of 75-80% may be expected. If such state-of-the-art integrated foot care is implemented, the majority of problems with foot ulcer recurrence in diabetes can be resolved. It is therefore time to act and to set a new target in diabetic foot care. This target is to reduce foot ulcer incidence with at least 75%.

Abstract
Objective. The aim of the study was to evaluate the prevalence of and risk factors for lower limb amputation in a specialist foot clinic-based setting. Methods. A retrospective quantitative study was conducted, using clinical and biochemical profiles of diabetic foot patients attending the High Risk Foot Clinic at The Townsville Hospital, Australia, between January 1, 2011, and December 31, 2013. Results. The total study sample included 129 subjects, comprising 81 males and 48 females with M : F ratio of 1.7 : 1. Twenty-three subjects were Indigenous Australians, representing 17.8% of the study population. The average age of the cohort was 63.4 years ± 14.1 years [CI 90.98-65.89]. Lower limb amputation was identified as a common and significant outcome (n = 44), occurring in 34.1%, more commonly amongst the Indigenous Australians (56.5% versus 29.2%; p = 0.94, OR 0.94). Risk factors most closely associated with amputation included diabetic retinopathy (p = 0.00, OR 4.4), coronary artery bypass graft (CABG) surgery (p = 0.01, OR 4.1), Charcot's arthropathy (p = 0.01, OR 2.9), and Indigenous ethnicity (p = 0.01, OR 3.4). Although average serum creatinine, corrected calcium, and glycosylated haemoglobin A1c (Hba1c) levels were higher amongst amputees they were statistically insignificant. Conclusions. Lower limb amputation is a common outcome and linked to ethnicity and neurovascular diabetic complications amongst subjects with diabetic foot ulcer. Further research is needed to identify why risk of lower limb amputation seems to differ according to ethnicity.

Abstract
Distal symmetric peripheral polyneuropathy (DSPN) is a highly prevalent complication of diabetes. However, underlying pathophysiological mechanisms are multiple and not well understood. The aim of our study was to analyze the oxidative stress levels in circulating mononuclear cells by measuring the glutathione system, malondialdehyde and oxidized-LDL, in 60 type 2 diabetic patients from a well-characterized cohort of 196 type 2 diabetic patients. Using a nested case-control design, we studied 30 type 2 diabetic patients with distal symmetric polyneuropathy and 30 diabetic controls without this complication, according to the Neuropathy Disability Score. We have found that diabetic patients with distal symmetric polyneuropathy showed significantly lower values of reduced glutathione (GSH) and reduced glutathione/oxidized glutathione (GSH/GSSG) ratio. These data indicate an increased consumption of glutathione in mononuclear cells from patients with distal symmetric polyneuropathy. No significant differences were found in malondialdehyde or in oxidized-LDL levels comparing both groups. These data show an altered glutathione response in circulating monocytes from diabetic patients with distal symmetric polyneuropathy.

Abstract
OBJECTIVE To examine the prevalence and predictors of foot disease, self-care and clinical monitoring in adults with type 2 diabetes in Alberta, Canada. METHOD Baseline data from a prospective cohort of adults with type 2 diabetes were used. Assessment of foot disease included self-reported peripheral neuropathy, peripheral vasculopathy, foot or leg ulcer/infection or gangrene/amputation. Foot self-care was assessed using the Summary of Diabetes Self-Care Activities, and clinical monitoring using patients' reports of having feet checked for lesions or sensory loss. RESULTS The mean age of respondents (N=2040) was 64 (SD 10.7) years; 45% were female, and 91% were Caucasian. Peripheral neuropathy was reported by 18% of the respondents, peripheral vasculopathy by 28%, ulcer/infection by 6% and gangrene/amputation by 1.4%. Only 14% of respondents performed foot self-care behaviours ≥6 days per week, and only 41% and 34% had their feet clinically checked for lesions or sensory loss, respectively. Predictors of foot disease included longer duration of diabetes, smoking, depressive symptoms, low self-efficacy and a history of cardiovascular diseases. Predictors of good self-care included older age, female sex, longer duration of diabetes and no report of hyperlipidemia. Predictors of clinical monitoring included female sex, current smoking, residing in urban areas, longer duration of diabetes, and histories of heart disease or hyperlipidemia. CONCLUSIONS Peripheral neuropathy and vasculopathy were the most common reported foot problems in this population. Foot self-care is generally infrequent, and clinical monitoring is performed for less than half of these patients, with significant variations by patient demographics and clinical presentation.

Abstract
Foot ulcerations in patients with diabetes are common. Most ulcers heal with conservative treatment, but recurrence is common. The pathway of ulcer development includes neuropathy, deformity, and trauma. The first attempt to avoid recurrence is by the use of shoes and insoles. When shoes and insoles fail, surgical correction of deformity leading to the ulcer can be attempted. This article reviews the most common procedures performed to heal ulcers or avoid recurrence.

Abstract
A great deal of emphasis, clinical and financial, is placed on limb salvage efforts in diabetic patients suffering from lower extremity ulceration. This is because of the impression that amputation in such patients may be a proximal cause of death. While amputation is certainly a negative clinical outcome, it is not entirely clear that it causes death. In this systematic review, we examine the available literature to attempt to understand the role that the ulceration itself may play in mortality. In brief, we searched for human studies in OVID, CINAHL and the COCHRANE CENTRAL DATABASE from 1980 to 2013, looking for articles related to ulcer or wound of the foot, in patients with diabetes or peripheral vascular disease, and death. We looked for articles with 5 years of follow-up, or Kaplan-Meier estimates of 5-year mortality, and excluded reviews and letters. Articles were assessed for quality and potential bias using the Newcastle-Ottawa scale. We find that while the patient populations studied varied widely in terms of demographics and comorbidities, limiting generalisability, 5-year mortality rates after ulceration were around 40%. Risk factors for death commonly identified were increased age, male gender, peripheral vascular disease and renal disease.

Abstract
BACKGROUND Diabetic foot ulcers (DFUs) are extremely debilitating and difficult to treat. Multidisciplinary management, patient education, glucose control, debridement, offloading, infection control, and adequate perfusion are the mainstays of standard care endorsed by most practice guidelines. Adjunctive therapies represent new treatment modalities endorsed in recent years, though many lack significant high-powered studies to support their use as standard of care. OBJECTIVE This update intends to identify recent, exclusively high level, evidence-based evaluations of DFU therapies. Furthermore, it suggests a direction for future research. METHODS PubMed, Embase, Ovid Technologies, CINAHL, Cochrane, and Web of Science databases were systematically searched for recent systematic reviews published after 2004, and randomized controlled trials published in 2012-2013 that evaluated treatment modalities for DFUs. These papers are reviewed and the quality of available evidence is discussed. RESULTS A total of 34 studies met inclusion criteria. Studied therapies include debridement, off-loading, negative pressure therapy, dressings, topical therapies, hyperbaric oxygen therapy, growth factors, bioengineered skin substitutes, electrophysical therapy, and alternative therapy. Good-quality evidence is lacking to justify the use of many of these therapies, with the exception of standard care (offloading, debridement) and possibly negative pressure wound therapy. LIMITATIONS There is an overall lack of high-level evidence in new adjunctive management of DFU. Comparison of different treatment modalities is difficult, since existing studies are not standardized. CONCLUSIONS Many therapeutic modalities are available to treat DFU. Quality high-level evidence exists for standard care such as off-loading. Evidence for adjunctive therapies such as negative pressure wound therapy, skin substitutes, and platelet-derived growth factor can help guide adjunctive care but limitations exist in terms of evidence quality.

Abstract
Neste trabalho estimamos o custo do tratamento hospitalar do pé diabético e discutimos a literatura referente à profilaxia destas lesões. Para isto revisamos os prontuários dos pacien tes submetidos a tratamento cirúrgico num período de 16 meses em um hospital público e revisamos os métodos de prevenção do pé diabético. Foram 44 internações com duração média de 11,93 dias (± 6,34), 61 procedimentos cirúrgicos, com amputações em 65% dos casos. Encontramos um custo médio de R$ 4.367,05 (± 9.249,01) e um custo total de R$ 192.150,40 para estes tratamentos hospitalares. O tratamento do pé diabético teve um alto custo e exigiu amputações na maioria dos casos. A revisão da literatura evidenciou diversos modelos possíveis de serem adotados para atuar na profilaxia de lesões associadas ao pé diabético, os quais podem evitar amputações e economizar recursos.

Abstract
Prevention is overlooked and underused, even in very high-risk patients. Prevention is best achieved within a multispecialty group of providers that have a common objective. Ideally, the team approach should include educators; physical therapists; nurses; internist; pedorthists; and vascular, orthopedic, and podiatric surgeons. The basic elements involve education, foot examination, risk classification, therapeutic shoes and insoles, and regular foot care. High-risk patients need additional assessment for vascular disease and intensive disease management, and corrective vascular and foot surgery when necessary. Basic interventions can reduce the incidence of foot ulcers by more than 50%.

Abstract
OBJECTIVE To determine the effect of contact with a podiatrist on the occurrence of Lower Extremity Amputation (LEA) in people with diabetes. DESIGN AND DATA SOURCES We conducted a systematic review of available literature on the effect of contact with a podiatrist on the risk of LEA in people with diabetes. Eligible studies, published in English, were identified through searches of PubMed, CINAHL, EMBASE and Cochrane databases. The key terms, 'podiatry', 'amputation' and 'diabetes', were searched as Medical Subject Heading terms. Reference lists of selected papers were hand-searched for additional articles. No date restrictions were imposed. STUDY SELECTION Published randomised and analytical observational studies of the effect of contact with a podiatrist on the risk of LEA in people with diabetes were included. Cross-sectional studies, review articles, chart reviews and case series were excluded. Two reviewers independently assessed titles, abstracts and full articles to identify eligible studies and extracted data related to the study design, characteristics of participants, interventions, outcomes, control for confounding factors and risk estimates. ANALYSIS Meta-analysis was performed separately for randomised and non-randomised studies. Relative risks (RRs) with 95% CIs were estimated with fixed and random effects models as appropriate. RESULTS Six studies met the inclusion criteria and five provided data included in meta-analysis. The identified studies were heterogenous in design and included people with diabetes at both low and high risk of amputation. Contact with a podiatrist did not significantly affect the RR of LEA in a meta-analysis of available data from randomised controlled trials (RCTs); (1.41, 95% CI 0.20 to 9.78, 2 RCTs) or from cohort studies; (0.73, 95% CI 0.39 to 1.33, 3 Cohort studies with four substudies in one cohort). CONCLUSIONS There are very limited data available on the effect of contact with a podiatrist on the risk of LEA in people with diabetes.

Abstract
Background. The Orthopaedic Podiatry Triage Clinic (OPodTC) is a ‘skill mix’ model of care developed in Queensland Health to address the problem of lengthy waiting times for orthopaedic surgery on foot and ankle pathologies. It is based on the recognition that many orthopaedic surgery referrals can be identified early and treated conservatively with podiatry, averting the need for more costly and invasive surgical interventions. The model is collaborative and relies on screening and triage by the podiatrist, rather than delegation by the orthopaedic surgeon. Methods. Screening and triage through OPodTC was trialled at three Queensland Health hospital facilities during 2009 and 2010 to improve service timeliness. Patients identified by the OPodTC podiatrist as suitable for conservative management were provided with non-surgical podiatry interventions and discharged if appropriate. Those identified as still requiring surgical intervention after the benefit of interim conservative treatment provided by the podiatrist (or who chose to remain on the list) were returned to their previous place on the orthopaedic waiting list. This paper presents a summary and description of waiting list changes in association with this trial. Results. The OPodTC intervention resulted in a reduction in the non-urgent category of the waiting list across the three hospitals of between 23.3% and 49.7%. Indications from wait-list service data demonstrated increased timeliness and improved patient flow, which are core goals of these skill mix initiatives. Conclusions. This study highlights the potential of screening and triage functions in the skill mix debate. In this example, conservative treatment options were considered first, suitable patients did not have to wait long periods to receive timely and appropriate interventions, and those for whom surgery was indicated, were provided with a more targeted service. What is known about the topic? Shifting and delegation of tasks is a key issue in current global debate on models of care. Discussion regarding the mix and shifting of tasks in podiatry and orthopaedic surgery has been limited in Australia, and the appropriate measurement of outcomes and processes is a point for discussion. What does this paper add? This paper describes such an initiative in podiatry and orthopaedic surgery. It describes a skill mix initiative based on triage and screening rather than delegation. It reflects benefits of including waiting lists as a process measure. What are the implications for practitioners? Support for triage-oriented skill mix collaboration in Podiatry and Orthopaedic Surgery.

Abstract
OBJECTIVES To identify areas of improvement in diabetic foot care as regards the availability of materials and specialties in primary and secondary care. To determine the model of care for surgical centres and hospitals caring for diabetic foot problems and their relation to amputations. DESIGN Cross-sectional study SETTING AND PARTICIPANTS Random sample of 36 basic health areas (BHA) and all hospital surgery centres in Catalonia (Spain). MEASUREMENTS Information was collected by structured interview of managers of each centre on: availability of specialists, material off-loading and examination. The models were established according to the classification of Van Acker, and amputations from hospital discharge records. RESULTS An endocrinologist was available in 36.1% [confidence interval (CI) 95%:19.0-53.2] of the BHA and 11.1% [95% CI: 3.1-26.1] had a podiatrist,100% [95% CI: 90.3-100.0] had Doppler, 91.7% [95% CI:77.5-98.2] a monofilament, 5.6% [95% CI: 0.7-18.7] a quantitative tuning fork, 11.1% [95% CI:3,1-26, 1] material off-loading, and 8.3% [95% CI: 1.8 - 22.5] a specialist reference centre. A total of 85 surgical centres and hospitals dealt with these problems: 11(13.0%) excellent model, 29 (34.1%) intermediate and 45 (52.9%) basic/insufficient. Centres with a basic model/insufficient performed 12.5% of the amputation, intermediate models, 56.4%, and 31.1% in excellent models. CONCLUSIONS The proportion of ABS with materials, specialists and/or specialist reference centres was low. The basic/insufficient model was the most common among surgical/hospital centres. Most amputations were performed in centres with excellent and intermediate model; nevertheless, a considerable percentage was performed in centres with basic/insufficient models.

Abstract
BACKGROUND The aims of the present study were to derive a foot risk index using administrative data similar to the International Working Group on the Diabetic Foot clinical risk classification scheme and to evaluate its association with the risk of initial lower extremity (through foot or above) amputation (ILEA). METHODS Merged Veterans Health Administration administrative and Medicare inpatient and outpatient claims data for a historical cohort of Veterans Health Administration users with diabetes were analyzed. Individuals with diabetes, aged ≥67 years in 1999, were classified into seven foot risk categories (where 0=no foot risk conditions; and 6=severe foot conditions). The outcome variable was the incidence of an ILEA over the period 2000-2004. Foot risk was derived from 1998 to 1999, and other independent variables were derived from 1999. The associations between foot risk category and risk of ILEA were evaluated using Cox proportional hazards regression models. RESULTS Of 255,534 individuals with diabetes, 54.8% had a documented foot condition in 1999 and 6869 (26.9 per 1000) had an ILEA over the period 2000-2004. We found increased rates of ILEAs as foot risk increased. Based on a Cox regression model containing all independent variables, the hazard ratios for risk of amputation increased progressively from 1.13 (95% CI 1.00-1.28) for the lowest foot risk category to 6.75 (95% CI 6.31-7.23) for the highest foot risk category, compared with individuals without defined foot conditions. CONCLUSIONS An administrative data-derived foot risk category was associated with risk of ILEA in a risk level-dependent pattern.

Abstract
Among the spectrum of risk for diabetic foot disease conferred by chronic kidney disease (CKD), end-stage renal disease (ESRD) has emerged as a novel independent risk factor. Apart from the classical triad of neuropathy, infection, and peripheral arterial disease that operate in these individuals, the risk is further compounded by inadequate foot self-care by patients and by dialysis centers not providing onsite foot care, as medical priorities are diverted to the dialysis itself. Consequently, the burden of diabetic foot disease has increased in the CKD and ESRD population as exemplified by high ulceration, amputation, and foot-related mortality rates. Current guidelines on foot care in diabetes should recognize advanced CKD and ESRD/dialysis as a separate risk factor for foot disease to alert professionals and highlight the opportunity for prevention. Recent studies have demonstrated improved foot outcomes when chiropody programs are instituted within dialysis units.
