Abstract
Nasal carriage of Staphylococcus aureus (SA) is an important risk factor for surgical site infections. The goal of this study was to investigate the concordance between nasal and diabetic foot ulcer (DFU) SA carriage. Seventy-nine subjects with DFUs were assessed for nasal and DFU colonization with SA, including methicillin-resistant SA (MRSA). Twenty-five (31.6%) subjects had nares colonization with SA; 29 (36.7%) had DFU colonization with SA. Seven (8.8%) subjects had nares colonization with MRSA, and 7 (8.8%) had DFU colonization with MRSA. Ulcer duration was associated with MRSA presence (P = 0.01). Sensitivity and specificity of positive nasal SA colonization with positive DFU colonization were 41% and 74%. We found substantial discordance between SA strains colonizing DFU and the nasal cavity. The poor positive predictive values for SA isolation in a DFU based on nasal carriage suggests that SA colonization of a DFU by endogenous SA strains cannot be assumed.

Abstract
OBJECTIVE Low health-related quality of life (HRQoL) has been consistently reported to be associated with poor prognosis for a variety of health outcomes in various settings. We aimed to evaluate whether HRQoL in patients presenting with new diabetic foot ulcers (DFUs) has prognostic significance for ulcer healing, major amputation, and death. RESEARCH DESIGN AND METHODS We followed 1,088 patients with new DFUs presenting for treatment at one of the 14 centers in 10 European countries participating in the Eurodiale (European Study Group on Diabetes and the Lower Extremity) study, prospectively until healing (76.9%), major amputation (4.6%), or death (6.4%) up to a maximum of 1 year. At baseline, patient and ulcer characteristics were recorded as well as EQ-5D, a standardized instrument consisting of five domains and a visual analog scale for use as a measure of HRQoL. The prognostic influence of the EQ-5D domains was evaluated in multivariable Cox regression analyses on the time-to-event data, adjusting for baseline clinical characteristics of the ulcer and comorbidities. RESULTS While predictive effects of HRQoL, adjusted for possible confounders, were absent for healing, decreased HRQoL, especially in the physical domains, was statistically significant for major amputation (mobility, self-care, usual activities) and death (self-care, usual activities, pain/discomfort). CONCLUSIONS Low HRQoL appears to be predictive for major amputation and death, but high HRQoL does not increase healing. Future studies into the influence of HRQoL on ulcer outcome are important in attempts to decrease treatment failure and mortality.

Abstract
OBJECTIVE To estimate the annual, per-patient incremental burden of diabetic foot ulcers (DFUs). RESEARCH DESIGN AND METHODS DFU patients and non-DFU patients with diabetes (controls) were selected using two de-identified databases: ages 65+ years from a 5% random sample of Medicare beneficiaries (Standard Analytical Files, January 2007-December 2010) and ages 18-64 years from a privately insured population (OptumInsight, January 2007-September 2011). Demographics, comorbidities, resource use, and costs from the payer perspective incurred during the 12 months prior to a DFU episode were identified. DFU patients were matched to controls with similar pre-DFU characteristics using a propensity score methodology. Per-patient incremental clinical outcomes (e.g., amputation and medical resource utilization) and health care costs (2012 U.S. dollars) during the 12-month follow-up period were measured among the matched cohorts. RESULTS Data for 27,878 matched pairs of Medicare and 4,536 matched pairs of privately insured patients were analyzed. During the 12-month follow-up period, DFU patients had more days hospitalized (+138.2% Medicare, +173.5% private), days requiring home health care (+85.4% Medicare, +230.0% private), emergency department visits (+40.6% Medicare, +109.0% private), and outpatient/physician office visits (+35.1% Medicare, +42.5% private) than matched controls. Among matched patients, 3.8% of Medicare and 5.0% of privately insured DFU patients received lower limb amputations. Increased utilization resulted in DFU patients having $11,710 in incremental annual health care costs for Medicare, and $16,883 for private insurance, compared with matched controls. Privately insured matched DFU patients incurred excess work-loss costs of $3,259. CONCLUSIONS These findings document that DFU imposes substantial burden on public and private payers, ranging from $9-13 billion in addition to the costs associated with diabetes itself.

Abstract
OBJECTIVE To determine whether patients with Wagner grades 1 and 2 diabetic foot ulcers (DFUs) or venous leg ulcers (VLUs) differed in terms of time to close depending on visit frequency to wound care centers. DESIGN Retrospective cohort study. SETTING Outpatients wound care centers. PATIENTS Two hundred six patients with Wagner grade 1 or 2 DFUs and 215 patients with VLUs in the lower extremities collected from 9 wound care centers in 5 states (6 states for VLUs) during 2009/2010 and whose wounds had closed. INTERVENTIONS For each type of DFU/VLU, 1 group had every-other-week visits, defined as more than 10 days between visits in the first 4 weeks, whereas the other group had weekly visits, defined as at least once a week. MAIN OUTCOMES MEASURES Median time to close. MAIN RESULTS For patients with DFUs, 63.8% of wounds had closed in the weekly visit group after 4 weeks compared with 2.0% in the every-other-week group (P = 2.3 × 10); for patients with VLUs, 78 of 105 wounds (52%) closed in the weekly visit group compared with 0% in the every-other-week group (P = 2.40 × 10). After controlling for all covariates in a Cox regression model, median time to close for weekly patients was 28 days versus 66 days for patients seen every other week. Adjusted median times to close VLUs in the same groups were 25 versus 55 days. CONCLUSIONS More frequent visits can be extremely beneficial, with implications of lower costs and higher quality of life for patients.

Abstract
BACKGROUND In the present study we: (i) evaluated the incidence of heart failure (HF) in patients with diabetic foot ulcer (DFU); and (ii) investigated the relationship between the clinical characteristics in these patients and prognosis. METHODS The clinical characteristics of 330 consecutive Chinese patients (137 men, 193 women) hospitalized for DFU were collected and assessed to determine the effects of HF on DFU. All patients were followed for 3 months and rates of healing, the development of new ulcers, amputations, and mortality were calculated at the end of the follow-up period. RESULTS Heart failure was present in 64.3% of patients with DFU, with the prevalence of HF increasing with Wagner grade from Wagner 1 through to Wagner 5 (42.4%, 59.1%, 64.7%, 73.3%, and 87.0%, respectively), higher than the 33.6% prevalence in diabetic patients without DFU (Wagner 0). The presence of HF conferred a greater increased relative risk of a worse prognosis. The 3-month healing rates of DFU in patients with and without HF were 60.3% and 75.7%, respectively. Recurrence (13.2% vs 7.5%) and amputations (28.6% vs 20.0%) were more frequent in patients with than without HF (P < 0.05). All-cause mortality was recorded for 14 of 126 patients with HF compared with three of 70 patients without HF (11.1% vs 4.3%, respectively; P < 0.05). CONCLUSIONS The prevalence of HF is high in Chinese inpatients with DFU, with the presence of HF indicating a worse prognosis for these patients.

Abstract
AIM To identify the factors responsible for the low health-related quality of life associated with foot ulcers and the relative importance of these factors. METHODS A total of 1232 patients with a new foot ulcer, who presented at one of the 14 centres in 10 European countries participating in the Eurodiale study, were included in this cross-sectional study. Patient and ulcer characteristics were obtained as well as results from the Euro-Qol-5D questionnaire, a health-related quality of life instrument with five domains (mobility, self-care, usual activities, pain/discomfort and anxiety/depression). To analyse the relative importance of comorbidities and ulcer- and patient-related factors for health-related quality of life, linear regression models were used to calculate the relative contributions of each factor to the fit (R(2) ) of the model. RESULTS Patients reported poor overall health-related quality of life, with problems primarily in the mobility and pain/discomfort domains. Among the comorbidities, the inability to stand or walk without help was the most important determinant of decreased health-related quality of life in all five domains. Among ulcer-related factors, ulcer size, limb-threatening ischaemia and elevated C-reactive protein concentration also had high importance in all domains. The clinical diagnosis of infection, peripheral arterial disease and polyneuropathy were only important in the pain/discomfort domain. CONCLUSIONS The factors that determine health-related quality of life are diverse and to an extent not disease-specific. To improve health-related quality of life, treatment should not only be focused on ulcer healing but a multifactorial approach by a specialized multidisciplinary team is also important.

Abstract
Introduction. Critical limb lschemia (CLI) and particularly diabetic foot (DF) are still considered “Cinderella” in our departments. Anyway, the presence of arterial obstructive disease increases the risk of amputation by itself; when it is associated with foot infection, the risk of amputation is greatly increased. Methods. From January 2007 to December 2011, 375 patients with DF infection and CLI have been admitted to our Unit; from 2007 to 2009, 192 patients (Group A) underwent surgical debridement of the lesion followed by a delayed revascularization; from 2010 to 2011, 183 patients (Group B) were treated following a new 4-step protocol: (1) early diagnosis with a 24 h on call DF team; (2) urgent treatment of severe foot infection with an aggressive surgical debridement; (3) early revascularization within 24 hours; (4) definitive treatment: wound healing, reconstructive surgery, and orthesis. We reported rates of mortality, major amputation, and foot healing at 6 months of followup. Results. The majority of patients in both groups were male; no statistical differences in medical history and clinical condition were reported at the baseline. The main difference between the two groups was the mean time from debridement to revascularization (3 days in Group A and 24 hours in Group B). After 6 months of follow-up, mortality was 11% in Group A versus 4.4% in Group B. Major amputation rate was 39.6% and 24.6% in Groups A and B, respectively. Wound healing was achieved in 17.8% in Group A and 20.8% in Group B. Conclusions. This protocol requires a lot of professional skills that should to reach the goal to avoid major amputations in patients with DF. Only an interdisciplinary integrated DF team and an early intervention may significantly impact the outcome of our patients: “Time is Tissue”!

Abstract
OBJECTIVES Due to the narrow therapeutic range and high drug-to-drug interactions (DDIs), improving the adequate use of warfarin for the elderly is crucial in clinical practice. This study examines whether the effectiveness of using warfarin among elderly inpatients can be improved when machine learning techniques and data from the laboratory information system are incorporated. METHODS Having employed 288 validated clinical cases in the DDI group and 89 cases in the non-DDI group, we evaluate the prediction performance of seven classification techniques, with and without an Adaptive Boosting (AdaBoost) algorithm. Measures including accuracy, sensitivity, specificity and area under the curve are used to evaluate model performance. RESULTS Decision tree-based classifiers outperform other investigated classifiers in all evaluation measures. The classifiers supplemented with AdaBoost can generally improve the performance. In addition, weight, congestive heart failure, and gender are among the top three critical variables affecting prediction accuracy for the non-DDI group, while age, ALT, and warfarin doses are the most influential factors for the DDI group. CONCLUSION Medical decision support systems incorporating decision tree-based approaches improve predicting performance and thus may serve as a supplementary tool in clinical practice. Information from laboratory tests and inpatients' history should not be ignored because related variables are shown to be decisive in our prediction models, especially when the DDIs exist.

Abstract
Critical limb ischemia, first defined in 1982, was intended to delineate a subgroup of patients with a threatened lower extremity primarily because of chronic ischemia. It was the intent of the original authors that patients with diabetes be excluded or analyzed separately. The Fontaine and Rutherford Systems have been used to classify risk of amputation and likelihood of benefit from revascularization by subcategorizing patients into two groups: ischemic rest pain and tissue loss. Due to demographic shifts over the last 40 years, especially a dramatic rise in the incidence of diabetes mellitus and rapidly expanding techniques of revascularization, it has become increasingly difficult to perform meaningful outcomes analysis for patients with threatened limbs using these existing classification systems. Particularly in patients with diabetes, limb threat is part of a broad disease spectrum. Perfusion is only one determinant of outcome; wound extent and the presence and severity of infection also greatly impact the threat to a limb. Therefore, the Society for Vascular Surgery Lower Extremity Guidelines Committee undertook the task of creating a new classification of the threatened lower extremity that reflects these important considerations. We term this new framework, the Society for Vascular Surgery Lower Extremity Threatened Limb Classification System. Risk stratification is based on three major factors that impact amputation risk and clinical management: Wound, Ischemia, and foot Infection (WIfI). The implementation of this classification system is intended to permit more meaningful analysis of outcomes for various forms of therapy in this challenging, but heterogeneous population.

Abstract
Most cases of lower extremity limb loss in the United States occur among people with diabetes who have a diabetic foot ulcer (DFU). These DFUs and the associated limb loss that may occur lead to excess healthcare costs and have a large negative impact on mobility, psychosocial well-being, and quality of life. The strategies for DFU prevention and management are evolving, but the implementation of these prevention and management strategies remains challenging. Barriers to implementation include poor access to primary medical care; patient beliefs and lack of adherence to medical advice; delays in DFU recognition; limited healthcare resources and practice heterogeneity of specialists. Herein, we review the contemporary outcomes of DFU prevention and management to provide a framework for prioritizing quality improvement efforts within a resource-limited healthcare environment.

Abstract
The forefoot has been reported as the most frequent location of osteomyelitis in the feet of patients with diabetes. The forefoot includes toes and metatarsal heads as common locations of bone infections, but the anatomy of these bones is quite different. As a result, such differences in anatomy may have an impact on the outcomes. The aim of the present study was to determine whether different locations of osteomyelitis in the forefoot have any influence on time to healing after undergoing surgery in a prospective series including 195 patients without peripheral arterial disease and osteomyelitis confirmed by histopathology. Location of the lesion was classified into 4 groups: hallux, first metatarsal head, lesser metatarsal heads, and lesser toes. The time required to achieve healing and the cumulative rate of wounds healed and likelihood of healing were analyzed at 4, 8, and 12 weeks after surgery. Time of healing (mean ± SD) in the whole series was 10.7 ± 8.4 weeks. Osteomyelitis located in the lesser toes has a higher probability of healing by the fourth week (odds ratio [OR] = 5.7, 95% confidence interval [CI] = 2.8-11.6, P < .001), eighth week (OR = 3.2, 95% CI = 1.6-6.4, P < .001), or twelfth week (OR = 3.1, 95% CI = 1.3-7.0, P = .008) than other osteomyelitis locations. Osteomyelitis located in the first metatarsal joint was less likely to heal by the eighth week (OR = 0.4, 95% CI = 0.2-0.9, P = .037) and 12th week (OR = 0.4, 95% CI = 0.2-1.0, P = .040). In conclusion, time to healing is significantly different according to the location of the bone infection in the forefoot.

Abstract
BACKGROUND After several exploratory and confirmatory clinical trials, the intralesional administration of human recombinant epidermal growth factor (hrEGF) has been approved for the treatment of advanced diabetic foot ulcers (DFU). The aim of this work was to evaluate the effectiveness and safety of this procedure in medical practice. METHODS A prospective, post-marketing active pharmacosurveillance was conducted in 41 hospitals and 19 primary care polyclinics. Patients with DFU received hrEGF, 25 or 75 μg, intralesionally 3 times per week until complete granulation of the ulcer or 8 weeks maximum, adjuvant to standard wound care. Outcomes measured were complete granulation, amputations, and adverse events (AE) during treatment; complete lesion re-epithelization and relapses in follow-up (median: 1.2; maximum 4.2 years). RESULTS The study included 1788 patients with 1835 DFU (81% Wagner's grades 3 or 4; 43% ischemic) treated from May 2007 to April 2010. Complete granulation was observed in 76% of the ulcers in 5 weeks (median). Ulcer non-ischemic etiology (OR: 3.6; 95% CI: 2.8-4.7) and age (1.02; 1.01-1.03, for each younger year) were the main variables with influence on this outcome. During treatment, 220 (12%) amputations (171 major) were required in 214 patients, mostly in ischemic or Wagner's grade 3 to 5 ulcers. Re-epithelization was documented in 61% of the 1659 followed-up cases; 5% relapsed per year. AE (4171) were reported in 47% of the subjects. Mild or moderate local pain and burning sensation, shivering and chills, were 87% of the events. Serious events, not related to treatment, occurred in 1.7% of the patients. CONCLUSIONS The favorable benefit/risk balance, confirms the beneficial clinical profile of intralesional hrEGF in the treatment of DFUs.

Abstract
It should now be possible to achieve a reduction in the incidence of foot ulceration and amputations as knowledge about pathways that result in both these events increases. However, despite the universal use of patient education and the hope of reducing the incidence of ulcers in high-risk patients, there are no appropriately designed large, randomized controlled trials actually confirming that education works. It has been recognized for some years that education as part of a multidisciplinary approach to care of the diabetic foot can help to reduce the incidence of amputations in certain settings. Ultimately, however, a reduction in neuropathic foot problems will only be achieved if we remember that the patients with neuropathic feet have lost their prime warning signal—pain—that ordinarily brings patients to their doctor. Very little training is offered to health care professionals as to how to deal with such patients. Much can be learned about the management of such patients from the treatment of individuals with leprosy: if we are to succeed, we must realize that with loss of pain there is also diminished motivation in the healing of and prevention of injury.

Abstract
PAD is very common in people with diabetes and is one of the strongest predictors of developing nonhealing foot ulcers and suffering amputation. There is strong evidence to show that early detection of PAD and revascularization will reduce amputations. Despite this, many patients have no vascular assessment even when they present with a foot ulcer or before amputation. Even when identified, patients are referred late, which worsens their outcome. Currently there is no evidence to support surgical revascularization over endovascular treatments, but in reality the techniques are complementary and the choice of revascularization procedure should be determined by an experienced multidisciplinary vascular team. Surgical revascularization can achieve good results but careful patient selection, operative planning, and the use of autologous vein are necessary. What is clearly apparent is that at present not enough patients are being offered revascularization to prevent amputation.

Abstract
Foot infections are common in persons with diabetes mellitus. Most diabetic foot infections occur in a foot ulcer, which serves as a point of entry for pathogens. Unchecked, infection can spread contiguously to involve underlying tissues, including bone. A diabetic foot infection is often the pivotal event leading to lower extremity amputation, which account for about 60% of all amputations in developed countries. Given the crucial role infections play in the cascade toward amputation, all clinicians who see diabetic patients should have at least a basic understanding of how to diagnose and treat this problem.

Abstract
Leg and foot ulcers are symptoms of very different diseases. The aim of this paper is to demonstrate the differential diagnosis of leg ulcers. The majority of leg ulcers occur in the lower leg or foot. In non-venous ulcers the localization in the foot area is more frequent. The most frequent underlying disease is chronic venous disease. In 354 leg ulcers, Koerber found 75.25% venous leg ulcers, 3.66% arterial leg ulcers, 14.66% ulcers of mixed venous and arterial origin and 13.5% vasculitic ulcers. In the Swedish population of Skaraborg, Nelzen found a venous origin in 54% of the ulcer patients. Each leg ulcer needs a clinical and anamnestic evaluation. Duplex ultrasound is the basic diagnostic tool to exclude vascular anomalies especially chronic venous and arterial occlusive disease. Skin biopsies help to find a correct diagnosis in unclear or non-healing cases. In conclusion, chronic venous disease is the most frequent cause of leg ulcerations. Because 25% of the population have varicose veins or other chronic venous disease the coincidence of pathological venous findings and ulceration is very frequent even in non-venous ulcerations. Leg ulcers without the symptoms of chronic venous disease should be considered as non-venous.

Abstract
Treatment strategies for foot at risk and diabetic foot are mainly preventive. Studies describing demographic data, clinical and impacting factors continue to be, however, scarce. Our objective was to determine the epidemiological presentation of diabetic foot and understand whether there were easily assessable variables capable of predicting the development of diabetic foot. This was a retrospective study of 496 patients with established foot at risk or diabetic foot, who were evaluated based on age, gender, type and duration of diabetes, foot at risk classification, and the presence of deformities, ulceration, and amputation. The presence of deformities, ulceration, and amputation was recorded in 45.9, 25.3, and 12.9 % of patients, respectively. As for diabetic foot classification, the great majority of our cohort had diabetic neuropathy (92.9 %). Approximately 30 % had neuro-ischemic disease and only 7.1 % had ischemic disease alone. Sixty-two percent of patients presented neuropathy with no signs of arteriopathy. Foot classification was as a significant predictor for the presence of ulcer (p = 0.009; OR = 3.2; 95 % CI = 1.18-7.3). Only male gender was a significant predictor for ulceration (p < 0.001). Predictors of amputation were male gender (p < 0.001; OR = 3.44 95 % CI = 1.81-6.56) and neuro-ischemic diabetic foot (p < 0.049; OR = 4.6; 95 % CI = 1.01-20.9). The predictors for diabetic foot were male gender and the presence of neuropathy. The combination of neuropathy and peripheral vascular disease adds significantly to the risk for amputation among patients with the diabetic foot syndrome. Men, presenting combined risk factors, should be a group receiving special attention and in the foot clinic, due to their potentially worse evolution.

Abstract
A longitudinal observational study on a convenience sample was conducted between 4 January and 31 December of 2010 to evaluate clinical outcomes that occur when a new Interprofessional Diabetes Foot Ulcer Team (IPDFUT) helps in the management of diabetes-related foot ulcers (DFUs) in patients living in a small urban community in Ontario, Canada. Eighty-three patients presented to the IPDFUT with 114 DFUs of average duration of 19·5 ± 2·7 weeks. Patients were 58·4 ± 1·4 years of age and 90% had type 2 diabetes, HbA1c of 8·3 ± 2·0%, with an average diabetes duration of 22·3 ± 3·4 years; in 69% of patients, 78 DFUs healed in an average duration of 7·4 ± 0·7 weeks, requiring an average of 3·8 clinic visits. Amputation of a toe led to healing in three patients (4%) and one patient required a below-knee amputation. Six patients died and three withdrew. Adding a skilled IPDFUT that is trained to work together resulted in improved healing outcomes. The rate of healing, proportion of wounds closed and complication rate were similar if not better than the results published previously in Canada and around the world. The IPDFUT appears to be a successful model of care and could be used as a template to provide effective community care to the patients with DFU in Ontario, Canada.

Abstract
BACKGROUND The aim of our study was to compare the effect of bone marrow mononuclear cell and peripheral blood progenitor cell therapies in patients with diabetic foot disease and critical limb ischaemia unresponsive to revascularization with conservative therapy. METHODS Twenty-eight patients with diabetic foot disease (17 treated by bone marrow cells and 11 by peripheral blood cell) were included into an active group and 22 patients into a control group without cell treatment. Transcutaneous oxygen pressure and rate of major amputation, as the main outcome measures, were compared between bone marrow cells, peripheral blood cell and control groups over 6 months; both cell therapy methods were also compared by the characteristics of cell suspensions. Possible adverse events were evaluated by changes of serum levels of angiogenic cytokines and retinal fundoscopic examination. RESULTS The transcutaneous oxygen pressure increased significantly (p < 0.05) compared with baseline in both active groups after 6 months, with no significant differences between bone marrow cells and peripheral blood cell groups; however, no change of transcutaneous oxygen pressure in the control group was observed. The rate of major amputation by 6 months was significantly lower in the active cell therapy group compared with that in the control group (11.1% vs. 50%, p = 0.0032), with no difference between bone marrow cells and peripheral blood cell. A number of injected CD34+ cells and serum levels of angiogenic cytokines after treatment did not significantly differ between bone marrow cells and peripheral blood cell. CONCLUSIONS Our study showed a superior benefit of bone marrow cells and peripheral blood cell treatments of critical limb ischaemia in patients with diabetic foot disease when compared with conservative therapy. There was no difference between both cell therapy groups, and no patient demonstrated signs of systemic vasculogenesis.

Abstract
BACKGROUND Healing of heel ulcers in patients with diabetes is considered to be poor, but there is relatively little information on the influence of ulcer location on ulcer healing. METHODS The influence of ulcer location on time to healing of diabetic foot ulcers was analysed by multivariate Cox regression analysis for 1000 patients included in the Eurodiale study, a prospective cohort study of patients with diabetic foot disease. RESULTS Median time to healing was 147 days for toe ulcers [(95% confidence interval (CI) 135-159 days)], 188 days for midfoot ulcers (95% CI 158-218 days) and 237 days for heel ulcers (95% CI 205-269 days) (p < 0.01). The median time to healing for plantar ulcers was 172 days (95% CI 157-187 days) and 155 days (95% CI 138-172 days) for nonplantar ulcers (p = 0.71). In multivariate Cox regression analysis, the hazard ratio for ulcer healing for midfoot and heel ulcers compared with toe ulcers was 0.77 (95% CI 0.64-0.92) and 0.62 (95% CI 0.47-0.83), respectively; the hazard ratio for ulcer healing for plantar versus nonplantar ulcers was 1 (95% CI 0.84-1.19). Other factors significantly influencing time to healing were the duration of diabetes, ulcer duration, the presence of heart failure and the presence of peripheral arterial disease. CONCLUSIONS Time to ulcer healing increased progressively from toe to midfoot to heel, but did not differ between plantar and nonplantar ulcers. Our data also indicate that risk factors for longer time to healing differ from factors that affect the ultimate number of ulcers that heal (healing rate).

Abstract
BACKGROUND Accumulation of advanced glycation end products (AGEs) may contribute to diabetic foot ulceration (DFU). Our goal was to determine whether AGEs measurement by skin autofluorescence (SAF) would be an additional marker for DFU management. PATIENTS AND METHODS We performed SAF analysis in 66 patients with a history of DFU prospectively included and compared the results with those of 84 control patients with diabetic peripheral neuropathy without DFU. We then assessed the prognostic value of SAF levels on the healing rate in the DFU group. RESULTS Mean SAF value was significantly higher in the DFU group in comparison with the control group, even after adjustment for other diabetes complications (3.2±0.6 arbitrary units vs. 2.9±0.6 arbitrary units; P=0.001). In the DFU group, 58 (88%) patients had an active wound at inclusion. The mean DFU duration was 14±13 weeks. The healing rate was 47% after 2 months of appropriate foot care. A trend for a correlation between SAF levels and healing time in DFU subjects was observed but was not statistically significant (P=0.06). CONCLUSIONS Increased SAF levels are associated with neuropathic foot complications in diabetes. Use of SAF measurement to assess foot vulnerability and to predict DFU events in high-risk patients appears to be promising.

Abstract
A decrease in rate of amputation has been reported from many countries. This study aims to study the trends in amputation rates in Germany. On the basis of DRG-system, detailed lists of all amputations coded as minor amputations (OPS 5-864) and major amputations (OPS 5-865) performed between 2005 and 2010 were provided by the Federal Statistical Office. There was a significant decrease in age-adjusted major amputation rates per 100 000 population in Germany from 27·0 in 2005 to 22·9 in 2010 (15·2%, P ≪ 0·001) in males and from 19·7 in 2005 to 14·4 in 2010 (26·9%, P ≪ 0·001) in females. Overall, minor amputation rates did not show such a decrease but increased in males (from 47·4 in 2005 to 57·8 in 2010, 21·9%, P ≪ 0·001) and remained almost unchanged in females (23·1 in 2005 and 23·9 in 2010, not significant). Reduction in major amputation rates were even more pronounced in people above 80 years, especially in males from 216 to 150 (30·5%) and in females from 168 to 117 (30·4%). The present data demonstrate an increasing overall burden of foot lesions as indicated by an increase in incidence of minor amputations but an ongoing success in the fight against amputation, resulting in a significant decrease in major amputation rates in Germany, in the 6-year period from 2005 to 2010.

Abstract
OBJECTIVE Peripheral arterial disease (PAD), as well as diabetic neuropathy, is a risk factor for the development of diabetic foot ulcers. The aim of this study was to evaluate differences and predictors of outcome parameters in patients with diabetic foot by stratifying these subjects according to the severity of PAD. RESEARCH DESIGN AND METHODS In a prospective study, patients with new diabetic foot ulcers have been treated and investigated by structured healthcare. Subjects were recruited between 1 January 2000 and 31 December 2007. All study participants underwent a 2-year follow-up observation period. The patients underwent a standardized examination and classification of their foot ulcers according to a modification of the University of Texas Wound Classification System. The severity of PAD was estimated by measurement of the ankle brachial index (ABI) and the continuous wave Doppler flow curve into undisturbed perfusion (0.9 < ABI < 1.3), compensated perfusion (0.5 < ABI < 0.9), decompensated perfusion (ABI < 0.5) and medial arterial calcification. RESULTS A total of 678 patients with diabetic foot were consecutively included into the study (69% male, mean age 66.3 ± 11.0 years, mean diabetes duration 15.8 ± 10.2 years). Major amputations (above the ankle) were performed in 4.7% of the patients. 22.1% of these subjects had decompensated PAD. These subjects had delayed ulcer healing, higher risk for major amputation [odds ratio (OR) 7.7, 95% confidence interval (CI) 2.8-21.2, p < 0.001] and mortality (OR 4.9, 95 % CI 1.1-22.1, p < 0.05). CONCLUSION This prospective study shows that the severity of PAD significantly influences the outcome of diabetic foot ulcers regarding to wound healing, major amputation and mortality.

Abstract
AIMS This study examined the predictors for lower extremity amputation (LEA) in patients with diabetic foot ulcers according to kidney function and, in the case of dialysis patients, specifically evaluated the vasculature with the ankle-brachial index (ABI) and Doppler waveforms. METHODS Among 658 diabetic patients admitted to the Diabetic Foot Care Center, 286 had an estimated glomerular filtration rate (eGFR)≥ 60 ml/min per 1.73 m(2), 275 had an eGFR<60, and 97 patients were under maintenance dialysis. All clinical variables were analyzed. A specialist retrospectively reviewed Doppler images of 78 of the patients in dialysis to evaluate peripheral arterial disease. RESULTS Forty-two percent of patients with eGFR<60 presented with ABI≤0.90. For ABI values>1.40, the proportion of dialysis patients (31.3%) was greater than the proportion of patients with eGFR<60 (5.3%). Wagner wound classifications, reduced serum albumin levels, and low ABI values were the predictors for major LEA among patients in the non-dialysis groups. Nevertheless, these indicators were not predictive of the risk of amputation in diabetic patients on dialysis. The presence of poor monophasic waveforms in the dorsalis pedis artery or posterior tibial artery served as an independent predictor (odds ratio: 7.61; P=0.008) for major LEA among dialysis patients. The sensitivity and specificity were 88.0% and 59.6%, respectively. CONCLUSIONS Poor monophasic Doppler waveforms of below-the-knee arteries, commonly found among dialysis patients in treatment for diabetic foot ulcers, can serve as an independent predictor for major LEA.

Abstract
Diabetic foot ulceration (DFU) is associated with high morbidity and mortality, and represents the leading cause of hospitalization in patients with diabetes. Peripheral arterial disease (PAD), present in half of patients with DFU, is an independent predictor of limb loss and can be difficult to diagnose in a diabetic population. This review focuses on the evidence for therapeutic strategies in the management of patients with DFU. We highlight the importance of timely referral of patients presenting with a new foot ulcer to a multidisciplinary team, which includes vascular surgeons and interventional radiologists.

Abstract
Objective We tested the effects of structured health care for the diabetic foot in one region in Germany aiming to reduce the number of major amputations. Research design and methods In a prospective study we investigated patients with diabetic foot in a structured system of outpatient, in-patient and rehabilitative treatment. Subjects were recruited between January 1st, 2000 and December 31, 2007. All participants underwent a two-year follow-up. The modified University of Texas Wound Classification System (UT) was the basis for documentation and data analysis. We evaluated numbers of major amputations, rates of ulcer healing and mortality. In order to compare the effect of the structured health care program with usual care in patients with diabetic foot we evaluated the same parameters at another regional hospital without interdisciplinary care of diabetic foot (controls). Results 684 patients with diabetic foot and 508 controls were investigated. At discharge from hospital 28.3% (structured health care program, SHC) vs. 23.0% (controls) of all ulcers had healed completely. 51.5% (SHC) vs. 49.8% (controls) were in UT grade 1. Major amputations were performed in 32 subjects of the structured health care program group (4.7%) vs. 110 (21.7%) in controls (p<0.0001). Mortality during hospitalization was 2.5% (SHC) vs. 9.4% in controls (p<0.001). Conclusions With the structured health care program we achieved a significant reduction of major amputation rates by more than 75% as compared to standard care.

Abstract
Diabetes-related foot disease is a major health problem leading to significant morbidity and cost. If high-risk populations could be identified and treated before they develop complications, a significant reduction in the burden of foot disease and number of amputations might be expected. We examined the evidence to support population-based screening programs. MEDLINE and EMBASE databases were searched from January 1970 to February 2012 to identify studies assessing the impact of screening on lower limb complications in diabetes. Foot screening was defined as combined risk stratification and intervention to prevent foot complications in a population of people with diabetes mellitus. Articles reporting singularly on stratification of risk factors to predict subsequent complications but not reporting effect on minor, major and/or combined major and minor (total) amputation were excluded. Two randomized control trials were identified. These demonstrated patient benefit from screening in the setting of a general secondary care diabetes clinic and renal dialysis unit. Four before and after studies suggested benefit from primary care or regional screening. One study tried to address confounding from general improvements in the provision of diabetes foot care separately from screening. All the observational studies were prone to confounding. The evidence base for formal national primary care-based foot screening of all patients with diabetes is weak. Focused research is needed to confirm that general population-based screening in the community is effective and cost-effective. Limited evidence suggests that screening of high-risk populations of patients may be justified.

Abstract
Background—
Recent technical advances have made endovascular treatment (EVT) an alternative first-line treatment for critical limb ischemia.
Methods and Results—
A prospective multicenter study was conducted to evaluate the clinical outcomes of 314 Japanese critical limb ischemia patients (mean age, 73±10 years) with infrainguinal arterial lesions who underwent EVT. Patients were enrolled from December 2009 to July 2011 and were followed-up for 12 months. The primary end point was amputation-free survival (AFS) at 12 months. Secondary end points were anatomic, clinical, and hemodynamic measures, including 12-month freedom from major adverse limb events. The 12-month AFS rate was 74%, with body mass index <18.5 (hazard ratio [HR], 2.22;
P
=0.008), heart failure (HR, 1.73;
P
=0.04), and wound infection (HR, 1.89;
P
=0.03) associated with a poor prognosis for AFS. The 12-month major adverse limb event-free rate was 88%, with hemodialysis (HR, 1.98;
P
=0.005), heart failure (HR, 1.69;
P
=0.02), and Rutherford classification 6 (HR, 2.25;
P
=0.002) associated with a poor prognosis for major adverse limb events. The median time for wound healing was 97 days, with body mass index <18.5 (HR, 0.54;
P
=0.03) and wound infection (HR, 0.60;
P
=0.04) being significant risk factors for unhealed wounds after EVT. At 12 months, 34% had undergone reintervention (bypass surgery, 2.6%; repeat EVT, 31.7%), and 73% were major adverse event–free.
Conclusions—
The high reintervention rate notwithstanding, EVT was an effective treatment for Japanese critical limb ischemia patients with infrainguinal disease, with satisfactory AFS and major adverse limb event-free rates. The results of this study will be helpful for the future evaluation of critical limb ischemia therapy.

Abstract
Diabetic neuropathy (DN) is the most common, most neglected and difficult to treat diabetic complication. It affects the whole body, and presents with diverse clinical pictures. The most important outcome of somatic and autonomic DN are the development of diabetic foot followed by diabetic ulceration and possible amputation. In this chapter the definition, epidemiology, pathophysiology and classification of somatic DN will be discussed. Attention will be given to various practical aspects of somatic DN of different types with their specific clinical presentation, diagnostic approaches and treatment options, including the usually rarely discussed gender differences. DN remains a problem in diabetology, compared to other micro- and macrovascular complications. The disease is rarely investigated, although simple testing devices for somatic nerve impairment exist, and remains difficult to treat because ofthe complex pathogenetic mechanisms. The main prevention/progression delaying measure for the progression of DN is the tight glycaemic control. Painful DN is common and need appropriate symptomatic relieving drugs. Future investigations must be targeted on new treatment options.

Abstract
OBJECTIVE The aim was to compare the efficacy and safety of two antibiotic regimens in patients with diabetic foot infections (DFIs). METHODS Data of a subset of patients enrolled in the RELIEF trial with DFIs requiring surgery and antibiotics were evaluated retrospectively. DFI was diagnosed on the basis of the modified Wagner, University of Texas, and PEDIS classification systems. Patients were randomized to receive either intravenous/oral moxifloxacin (MXF, N = 110) 400 mg q.d. or intravenous piperacillin/tazobactam 4.0/0.5 g t.d.s. followed by oral amoxicillin/clavulanate 875/125 mg b.d. (PIP/TAZ-AMC, N = 96), for 7-21 days until the end of treatment (EOT). The primary endpoint was clinical cure rates in the per-protocol (PP) population at the test-of-cure visit (TOC, 14-28 days after EOT). RESULTS There were no significant differences between the demographic characteristics of PP patients in either treatment group. At TOC, MXF and PIP/TAZ-AMC had similar efficacy in both the PP and intent-to-treat (ITT) populations: MXF: 76.4 % versus PIP/TAZ-AMC: 78.1 %; 95 % confidence interval (CI) -14.5 %, 9.0 % in the PP population; MXF: 69.9 % versus PIP/TAZ-AMC: 69.1 %; 95 % CI -12.4 %, 12.1 % in the ITT population. The overall bacteriological success rates were similar in both treatment groups (MXF: 71.7 % versus PIP/TAZ-AMC: 71.8 %; 95 % CI -16.9 %, 10.7 %). A similar proportion of patients (ITT population) experienced any adverse events in both treatment groups (MXF: 30.9 % versus PIP/TAZ-AMC: 31.8 %, respectively). Death occurred in three MXF-treated patients and one PIP/TAZ-AMC-treated patient; these were unrelated to the study drugs. CONCLUSION Moxifloxacin has shown favorable safety and efficacy profiles in DFI patients and could be an alternative antibiotic therapy in the management of DFI. CLINICAL TRIAL NCT00402727.

Abstract
This review discusses the role of endovascular treatment in diabetic patients with critical limb ischemia (CLI). Angioplasty of the femoropopliteal region achieves similar technical success and limb salvage rates in diabetic and nondiabetic patients. Angioplasty in as many as possible tibial vessels is accompanied by more complete and faster ulcer healing as well as better limb salvage rates compared to isolated tibial angioplasty. Targeted revascularization of a specific vessel responsible for the perfusion of a specific ulcerated area is a promising new approach: it replaces revascularization of the angiographically easiest-to-access tibial vessel, even if this is not directly responsible for the perfusion of the ulcerated area, by revascularization of area-specific vascular territories. In conclusion, the endovascular approach shows very high efficacy in ulcer healing for diabetic patients with CLI. Larger prospective studies are now needed to estimate the long-term results of this approach.

Background The management of chronic diabetic foot ulcers (DFU) poses a great challenge to the treating physician and surgeon. The aim of this study was to identify the risk factors, clinical presentation, and outcomes associated with chronic DFU>6 months’ duration. Methods This prospective study was performed in Jabir Abu Eliz Diabetic Centre (JADC), Khartoum, Sudan. A total of 108 patients who had DFU for >6 months were included. Recorded data included patient's demographics, DFU presentation, associated comorbidities, and outcomes. DFU description included size, depth, protective sensation, perfusion, and presence of infection. Comorbidities assessed included eye impairment, renal and heart disease. All patients received necessary local wound care with sharp debridement of any concomitant necrotic and infected tissues and off-loading with appropriate shoe gear and therapeutic devices. Results The mean age of the studied patients was 56+SD 9 years with a male to female ratio of 3:3.3. The mean duration of DFU was 18±SD 17 months (ranging from 6 to 84 months). Ulcer healing was significantly associated with off-loading, mainly the use of total contact cast (TCC) (p=0.013). Non-healing ulcerations were significantly associated with longer duration of the chronic DFU>12 months (p=0.002), smoking (p=0.000), poor glycemic control as evidenced by an elevated HbA1c (>7%), large size (mean SD 8+4 cm), increased depth (p<0.001), presence of skin callus (p<0.000), impaired limb perfusion (p=0.001), impaired protective sensation as measured by 10 g monofilament (p=0.002), neuroischemia (p=0.002), and Charcot neuroarthropathy (p=0.017). Discussion Risk factors associated with chronic DFU of>6 months’ duration included the presentation of an ulcer with increased size and depth, with associated skin callus and neuroischemia, in a diabetic patient with a history of smoking and increased HbA1c >7%. Off-loading mainly with the use of TCC is an effective method of managing long-standing DFU.

Abstract
OBJECTIVE There is a dearth of long-term data regarding patient and limb survival in patients with diabetic foot ulcers (DFUs). The purpose of our study was therefore to prospectively investigate the limb and person survival of DFU patients during a follow-up period of more than 10 years. RESEARCH DESIGN AND METHODS Two hundred forty-seven patients with DFUs and without previous major amputation consecutively presenting to a single diabetes center between June 1998 and December 1999 were included in this study and followed up until May 2011. Mean patient age was 68.8 ± 10.9 years, 58.7% were male, and 55.5% had peripheral arterial disease (PAD). Times to first major amputation and to death were analyzed with Kaplan-Meier curves and Cox multiple regression. RESULTS A first major amputation occurred in 38 patients (15.4%) during follow-up. All but one of these patients had evidence of PAD at inclusion in the study, and 51.4% had severe PAD [ankle-brachial pressure index ≤0.4]). Age (hazard ratio [HR] per year, 1.05 [95% CI, 1.01-1.10]), being on dialysis (3.51 [1.02-12.07]), and PAD (35.34 [4.81-259.79]) were significant predictors for first major amputation. Cumulative mortalities at years 1, 3, 5, and 10 were 15.4, 33.1, 45.8, and 70.4%, respectively. Significant predictors for death were age (HR per year, 1.08 [95% CI, 1.06-1.10]), male sex ([1.18-2.32]), chronic renal insufficiency (1.83 [1.25-2.66]), dialysis (6.43 [3.14-13.16]), and PAD (1.44 [1.05-1.98]). CONCLUSIONS Although long-term limb salvage in this modern series of diabetic foot patients is favorable, long-term survival remains poor, especially among patients with PAD or renal insufficiency.

Abstract
To investigate the characteristics of diabetic patients with foot ulcers, their health-related quality of life (HRQoL), and the link between them. The study population included 131 consecutive patients presenting in a diabetic foot clinic with a new foot ulcer between December 1, 2011, and May 1, 2012. The authors collected sociodemographic data, foot and ulcer characteristics using the Wagner Grade, and HRQoL (using the SF-36 Scale) information; 54.2% of the patients were in Wagner 2 or Wagner 3 categories. In all the 8 SF-36 subscales and in the SF-36 summary scales, the patients with diabetic foot ulcer had significantly poorer HRQoL than the general population in China ( P < .01). Their Wagner Grade had negative correlation with all the SF-36 subscales and the summary scales ( P < .05). In conclusion, new diabetic foot ulcers were already in poor condition when patients first visited the diabetic foot clinic. Concomitantly, patients had worse HRQoL compared with the general population. More effective interventions are needed to improve their self-care level and HRQoL.

Abstract
Foot infections are a common and serious problem in persons with diabetes. Diabetic foot infections (DFIs) typically begin in a wound, most often a neuropathic ulceration. While all wounds are colonized with microorganisms, the presence of infection is defined by ≥2 classic findings of inflammation or purulence. Infections are then classified into mild (superficial and limited in size and depth), moderate (deeper or more extensive), or severe (accompanied by systemic signs or metabolic perturbations). This classification system, along with a vascular assessment, helps determine which patients should be hospitalized, which may require special imaging procedures or surgical interventions, and which will require amputation. Most DFIs are polymicrobial, with aerobic gram-positive cocci (GPC), and especially staphylococci, the most common causative organisms. Aerobic gram-negative bacilli are frequently copathogens in infections that are chronic or follow antibiotic treatment, and obligate anaerobes may be copathogens in ischemic or necrotic wounds. Wounds without evidence of soft tissue or bone infection do not require antibiotic therapy. For infected wounds, obtain a post-debridement specimen (preferably of tissue) for aerobic and anaerobic culture. Empiric antibiotic therapy can be narrowly targeted at GPC in many acutely infected patients, but those at risk for infection with antibiotic-resistant organisms or with chronic, previously treated, or severe infections usually require broader spectrum regimens. Imaging is helpful in most DFIs; plain radiographs may be sufficient, but magnetic resonance imaging is far more sensitive and specific. Osteomyelitis occurs in many diabetic patients with a foot wound and can be difficult to diagnose (optimally defined by bone culture and histology) and treat (often requiring surgical debridement or resection, and/or prolonged antibiotic therapy). Most DFIs require some surgical intervention, ranging from minor (debridement) to major (resection, amputation). Wounds must also be properly dressed and off-loaded of pressure, and patients need regular follow-up. An ischemic foot may require revascularization, and some nonresponding patients may benefit from selected adjunctive measures. Employing multidisciplinary foot teams improves outcomes. Clinicians and healthcare organizations should attempt to monitor, and thereby improve, their outcomes and processes in caring for DFIs.

Abstract
OBJECTIVE This study was designed to evaluate the association between skin autofluorescence (AF), an indicator of advanced glycation end-products (AGEs), and foot ulcers in subjects with diabetes. METHODS In this study, 195 Chinese diabetic subjects were examined. Their feet were examined regardless of whether an ulcer was present or not. Skin AF was measured with an AGE reader. Demographic characteristics and blood data were recorded. RESULTS The mean values of skin AF were 2.29 ± 0.47 for subjects without foot ulcers, and 2.80 ± 0.69 for those with foot ulcers, a significant difference (P<0.05). Skin AF was strongly correlated with age and duration of diabetes. After adjusting for these factors, multivariate logistic regression showed that skin AF was independently associated with foot ulcerations. CONCLUSIONS Skin AF is independently associated with diabetic foot ulcerations. It might be a useful screening method for foot ulceration risk of diabetic patients.

Abstract
OBJECTIVE This study aimed to quantify the impact of an integrated diabetic foot surgical service on outcomes and changes in surgical volume and focus. METHODS We abstracted registry data from 48 consecutive months at a single institution, evaluating all patients with diabetic foot complications requiring surgery or vascular intervention, and compared outcomes in the 24 months before and after integrating podiatric surgery with vascular surgical limb-salvage service. RESULTS The service performed 2923 operations; 790 (27.0%) were related to treatment of diabetic foot complications in 374 patients. Of these, 502 were classified as non-vascular diabetic foot surgery and 288 were vascular interventions. Urgent surgery was significantly reduced after team implementation (77.7% vs 48.5%, p < 0.0001; OR = 3.7, 95% CI: 2.4-5.5). The high/low amputation ratio decreased from 0.35 to 0.27 due to an increase in low-level (midfoot) amputations (8.2% vs 26.1%, p < 0.0001; OR = 4.0, 95% CI: 2.0-83.3). A 45.7% reduction in below-knee amputations was realized with a stable above-knee/below-knee amputation ratio (0.73-0.81). One-third of patients required vascular intervention. Vascular reconstructions increased 44.1% following institution of the team. Initial revascularization was endovascular in 70.6% of patients. Repeat endovascular intervention or conversion to open bypass was required in 37.1% of these patients, almost double the reintervention rate of those receiving open bypass first (18.9%). CONCLUSIONS Interdisciplinary diabetic foot surgery teams may significantly impact surgery type, with greater focus on proactive and preventive, rather than reactive and ablative, procedures. Although endovascular limb-sparing procedures have become increasingly applicable, open bypass remains critical to success.

Duration of off-loading and recurrence rate in Charcot osteo-arthropathy treated with less restrictive regimen with removable walker. J Diabetes Complications 2012; 26:430-4.

Abstract
OBJECTIVE Recent literature on acute diabetic Charcot osteoarthropathy (CA) reports unusually long periods of off-loading. Data suggest that this might increase the re-currence rate. Subsequently we evaluated the influence of duration of off-loading on the risk of required re-casting. RESEARCH DESIGN AND METHODS In this retrospective consecutive series from 2000 to 2005, 56 people with diabetes and an acute Charcot foot were included. The inclusion criteria were an initial persistent temperature difference more than 2°C between the two feet, oedema, and typical hot spots on a bone scintigram, radiology, and a typical clinical course. Treatment was off-loading in a removable cast and 2 crutches. In-door walking was allowed. Gradually augmented weight bearing was prescribed when the skin temperature difference had decreased to a level less than 2°C and edema had subsided. Re-casting was required for immediate exacerbation during re-load as well as for recurrence - defined as new swelling and skin temperature difference of more than 2°C in the same foot occurring after a stable interval of at least one month after full weight bearing. RESULTS The duration of off-loading for all patients was 141±21 days (mean±SD). Three patients (5%) were re-casted immediately for exacerbation after re-load and 7 patients (12 %) after recurrence of the CA. Duration of re-casting was 79±44 days. The primary period of off-loading was not statistically significantly different for those not requiring versus those requiring re-casting: 142±24 days compared to 134±41 days. Neither were the differences in demographic data, metabolic regulation, BMI or localization of CA. CONCLUSIONS Patients with risk of exacerbation or recurrence of CA could not be identified in the present study and there was no relation to the duration of off-loading. Nevertheless off-loading periods with immobilisation should be kept as short as possible, due to other side effects. This can be obtained by early gradual augmented re-loading.
