Abstract
BACKGROUND Despite a meticulous multidisciplinary team approach, limb salvage remains uncertain even after the initial forefoot amputation in patients with end-stage diabetes. Which of many factors strongly influence the early failure of the limb salvage strategy remains unknown. This study aimed to analyze perioperative independent risk factors for major amputation within 1 year following first-time diabetic forefoot amputation. METHODS Perioperative variables of 808 diabetic forefoot amputations performed in a tertiary referral center specialized for organ transplantation and end-stage diabetes were analyzed. Major amputations were performed in 104 patients (12.9%) throughout follow-up, and 77 (74%) of 104 patients had their major amputation within 1 year. Cox proportional hazards were examined to assess the risk factors for major amputation performed within 1 year. RESULTS In univariate analysis, 18 possible risk factors significantly differed between patients with and without early major amputation. In stepwise multivariable analysis, chronic renal failure (CRF), peritoneal dialysis, and bilateral initial amputation were strong risk factors for early major amputation, with hazard ratios of 2.973 (95% CI 1.805-4.896, P < .0001), 2.558 (95% CI 1.113-5.881, P = .027), and 2.515 (95% CI 1.318-4.798, P = .005), respectively. CONCLUSION Regardless of kidney transplantation (KT) status, CRF strongly predicts >20% chance of major amputation within 1 year after the first diabetic forefoot amputation.

Abstract
The aim of the current study was to evaluate the outcomes of patients with diabetic foot osteomyelitis (DFO), comparing subjects with and without peripheral arterial disease (PAD). The study is a prospective study including a population of patients affected by a DFO located in the forefoot. All patients were managed by a surgical conservative approach defined by the removal of the infected bone, in association with the antibiotic therapy. Patients were divided into two groups: those with PAD (neuro-ischaemic DFO) and those without (neuropathic DFO). After 1 year of follow-up, the following outcome were evaluated and compared between groups: healing, healing time, minor amputation, major amputation, hospitalization, need for surgical re-intervention. Overall, 166 patients were included, 87(52.4%) of them had neuro-ischaemic DFO and 79 (47.6%) neuropathic DFO. Patients with neuro-ischaemic DFO in comparison to neuropathic DFO were older (72.5 ± 9 vs 64.1 ± 15.5 years, P < .0001), had longer diabetes duration (21.8 ± 5.6 vs 16.4 ± 7.6 years, P < .0001), higher rate of dialysis (13.8 vs 1.3%, P = .001) and ischaemic heart disease (79.3 vs 12.7%, P < .0001). Outcomes for neuro-ischaemic DFO and neuropathic DFO were: healing (96.5 vs 97.5%, P = .7), healing time (7.8 ± 6.2 vs 5.7 ± 3.7 weeks, P = .01), minor amputation (16.1 vs 3.8%, P = .006), major amputation (0 vs 0%, ns), hospitalization (90.8 vs 51.9%, P < .0001), surgical re-intervention (14.9 vs 8.8%, P = .004) respectively. In addition, PAD resulted in an independent predictor of minor amputation, hospitalization, and surgical re-intervention. DFO in patients with PAD was characterized by longer healing time, more cases of minor amputation, hospitalization, and surgical re-intervention. PAD independently predicted the risk of minor amputation, hospitalization, and surgical re-intervention, while it was not associated with the healing rate.

Abstract
Objective To investigate the risk factors associated with prolonged hospitalization in patients diagnosed with diabetic foot ulcers (DFU), to develop a predictive model, and to conduct internal validation of the model. Methods The clinical data of DFU patients admitted to West China Hospital, Sichuan University between January 2012 and December 2022 were retrospectively collected. The subjects were randomly assigned to a training cohort and a validation cohort at a ratio of 7 to 3. Hospital stays longer than 75th percentile were defined as prolonged length-of-stay. A thorough analysis of the risk factors was conducted using the training cohort, which enabled the development of an accurate risk prediction model. To ensure robustness, the model was internally validated using the validation cohort. Results A total of 967 inpatients with DFU were included, among whom 245 patients were identified as having an extended length-of-stay. The training cohort consisted of 622 patients, while the validation cohort comprised 291 patients. Multivariate logistic regression analysis revealed that smoking history (odds ratio [OR]=1.67, 95% confidence interval [CI], 1.13 to 2.48, P=0.010), Wagner grade 3 or higher (OR=7.13, 95% CI, 3.68 to 13.83, P<0.001), midfoot ulcers (OR=1.99, 95% CI, 1.07 to 3.72, P=0.030), posterior foot ulcers (OR=3.68, 95% CI, 1.83 to 7.41, P<0.001), multisite ulcers (OR=2.91, 95% CI, 1.80 to 4.69, P<0.001), wound size≥3 cm2 (OR=2.00, 95% CI, 1.28-3.11, P=0.002), and white blood cell count (OR=1.11, 95% CI, 1.05 to 1.18, P<0.001) were associated with an increased risk of prolonged length of stay. Additionally, a nomogram was constructed based on the identified risk factors. The areas under the receiver operating characteristic (ROC) curves for both the training cohort and the validation cohort were 0.782 (95% CI, 0.745 to 0.820) and 0.756 (95% CI, 0.694 to 0.818), respectively, indicating robust predictive performance. Furthermore, the calibration plot demonstrated optimal concordance between the predicted probabilities and the observed outcomes in both the training and the validation cohorts. Conclusion Smoking history, Wagner grade≥3, midfoot ulcers, posterior foot ulcers, multisite ulcers, ulcer area≥3 cm2, and elevated white blood cell count are identified as independent predictors of prolonged hospitalization. Therefore, it is imperative that clinicians conduct a comprehensive patient evaluation and implement appropriate diagnostic and therapeutic strategies to effectively shorten the length of stay for DFU patients.

Abstract
BACKGROUND Diabetic foot ulcers are caused by a variety of factors, including peripheral neuropathy, peripheral arterial disease, impaired wound healing mechanisms, and repetitive trauma. Patients with diabetic foot ulcer on the dorsum of the foot are often treated surgically. However, the right non-surgical therapy must be chosen if surgical choices are contraindicated or if the patient prefers conservative treatment over surgery. CASE SUMMARY The purpose of this case report is to highlight the efficacy of polydeoxyribonucleotide (PDRN) injection as a non-surgical treatment option for diabetic foot ulcers on the dorsum of the foot, particularly in patients who choose against surgical intervention. This case report presents two cases of diabetic foot ulcers located on the dorsum of the foot that were successfully treated with PDRN injection as a non-surgical intervention. CONCLUSION If the patient declines surgery for diabetic ulcers with Wagner grade II or below, PDRN injection can be effective if necrotic tissue is removed and the wound bed kept clean.

Abstract
BACKGROUND Diabetes mellitus, as one of the world's fastest-growing diseases, is a chronic metabolic disease that has now become a public health problem worldwide. The purpose of this research was to develop a predictive nomogram model to demonstrate the risk of major amputation in patients with diabetic foot. METHODS A total of 634 Type 2 Diabetes Mellitus (T2DM) patients with diabetic foot ulcer hospitalized at the Air Force Medical Center between January 2018 and December 2023 were included in our retrospective study. There were 468 males (73.82%) and 166 females (26.18%) with an average age of 61.64 ± 11.27 years and average body mass index of 24.45 ± 3.56 kg/m2. The predictive factors were evaluated by single factor logistic regression and multiple logistic regression and the predictive nomogram was established with these features. Receiver operating characteristic (subject working characteristic curve) and their area under the curve, calibration curve, and decision curve analysis of this major amputation nomogram were assessed. Model validation was performed by the internal validation set, and the receiver operating characteristic curve, calibration curve, and decision curve analysis were used to further evaluate the nomogram model performance and clinical usefulness. RESULTS Predictors contained in this predictive model included body mass index, ulcer sites, hemoglobin, neutrophil-to-lymphocyte ratio, blood uric acid (BUA), and ejection fraction. Good discrimination with a C-index of 0.957 (95% CI, 0.931-0.983) in the training group and a C-index of 0.987 (95% CI, 0.969-1.000) in the validation cohort were showed with this predictive model. Good calibration were displayed. The decision curve analysis showed that using the nomogram prediction model in the training cohort and validation cohort would respectively have clinical benefits. CONCLUSION This new nomogram incorporating body mass index, ulcer sites, hemoglobin, neutrophil-to-lymphocyte ratio, BUA, and ejection fraction has good accuracy and good predictive value for predicting the risk of major amputation in patients with diabetic foot.

Abstract
In this Review, we aim to complement the 2023 update of the guidelines of the International Working Group on the Diabetic Foot. We highlight the complexity of the pathological processes that underlie diabetes-related foot ulceration (DFU) and draw attention to the potential implications for clinical management and outcome. Variation observed in the incidence and outcome of DFUs in different communities might result from differences in study populations and the accessibility of care. Comparing differences in incidence, management, and outcome of DFUs in different communities is an essential component of the quality of disease care. Additionally, these comparisons can also highlight the relationship between DFU incidence, management, and outcome and the structure of local clinical services and the availability of staff with the necessary skills. The clinical outcome is, however, also dependent on the availability of multidisciplinary care and the ability of people with DFUs to gain access to that care.

Abstract
INTRODUCTION To assess the efficacy of a chitosan-based gel (ChitoCare) for the treatment of non-healing diabetic foot ulcers (DFUs). RESEARCH DESIGN AND METHODS Forty-two patients with chronic DFUs were randomized to the ChitoCare or placebo gel for a 10-week treatment period and 4-week follow-up. The primary study end point was the rate of complete wound closure at week 10, presented as relative rate. RESULTS Thirty patients completed the 10-week treatment and 28 completed the 4-week follow-up. The ChitoCare arm achieved 16.7% complete wound closure at week 10 vs 4.2% in the placebo arm (p=0.297), 92.0% vs 37.0% median relative reduction in wound surface area from baseline at week 10 (p=0.008), and 4.62-fold higher likelihood of achieving 75% wound closure at week 10 (p=0.012). Based on the results of the Bates-Jensen Wound Assessment Tool, the wound state at week 10 and the relative improvement from the baseline were significantly better (median 20 vs 24 points, p=0.018, and median 29.8% vs 3.6%, p=0.010, respectively). CONCLUSIONS ChitoCare gel increased the rate of the DFU healing process. Several secondary end points significantly favored ChitoCare gel. TRIAL REGISTRATION NUMBER NCT04178525.

Abstract
BACKGROUND The global number of people with diabetes is estimated to reach 643 million by 2030 of whom 19-34% will present with diabetic foot ulceration. Insoles which offload high-risk ulcerative regions on the foot, by removing insole material, are the main contemporary conservative treatment to maintain mobility and reduce the likelihood of ulceration. However, their effect on the rest of the foot and relationship with key gait propulsive and balance kinematics and kinetics has not been well researched. PURPOSE The aim of this study is to investigate the effect of offloading insoles on gait kinematics, kinetics, and plantar pressure throughout the gait cycle. METHODS 10 healthy subjects were recruited for this experiment to walk in 6 different insole conditions. Subjects walked at three speeds on a treadmill for 10 minutes while both plantar pressure and gait kinematics, kinetics were measured using an in-shoe pressure measurement insole and motion capture system/force plates. Average peak plantar pressure, pressure time integrals, gait kinematics and centre of force were analysed. RESULTS The average peak plantar pressure and pressure time integrals changed by -30% (-68% to 3%) and -36% (-75% to -1%) at the region of interest when applying offloading insoles, whereas the heel strike and toe-off velocity changed by 15% (-6% to 32%) and 12% (-2% to 19%) whilst walking at three speeds. CONCLUSION The study found that offloading insoles reduced plantar pressure in the region of interest with loading transferred to surrounding regions increasing the risk of higher pressure time integrals in these locations. Heel strike and toe-off velocities were increased under certain configurations of offloading insoles which may explain the higher plantar pressures and supporting the potential of integrating kinematic gait variables within a more optimal therapeutic approach. However, there was inter-individual variability in responses for all variables measured supporting individualised prescription.

Identification, influencing factors and outcomes of time delays in the management pathway of diabetic foot: A systematic review. J Tissue Viability 2024; 33:345-354. [PMID: 38594149 DOI: 10.1016/j.jtv.2024.04.007] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/25/2023] [Revised: 01/23/2024] [Accepted: 04/04/2024] [Indexed: 04/11/2024]
Abstract
OBJECTIVE A systematic review was conducted to evaluate the time delays in the management of diabetic foot and explore influencing factors of these delays and potential outcomes. METHODS The researchers searched several electronic databases (Pubmed, Web of Science, Cochrane Library, EMbase, CNKI, WanFang, CBM and VIP) for English and Chinese studies that examined time delays in the management pathway of diabetic foot. Two authors independently screened and extracted data, and assessed the quality of the included studies using the Newcastle-Ottawa Scale and the Agency for Health Research and Quality checklist. Due to heterogeneity among the studies, descriptive analysis was performed. RESULTS The review included 28 articles, comprising 20 cohort studies and 8 cross-sectional studies, that met the inclusion criteria. Among these, 14 were deemed of high quality. The median times from symptom onset to primary health care or specialist care varied from 3 to 46.69 days. The median delay in referral by primary care specialists ranged from 7 to 31 days, and subsequent median times to definitive treatment ranged from 6.2 to 56 days. Multiple complex factors were found to contribute to these delays, including patient demographics (older age, lower education level and income level) and poor patient health-seeking behaviors (inaccurate self-treatment, incorrect recognition and interpretation of symptoms), inaccurate assessment or initial treatment by health primary professionals, complex referral pathways and clinical characteristics of diabetic foot (number of foot ulcers, Wagner grade scale, and hemoglobin A1c index). Negative outcomes associated with these delays included increased risk of major amputation and mortality, decreased wound healing rate, prolonged hospital stay, and increased hospital costs. CONCLUSIONS Time delays in the diabetic foot management pathway were both common and serious, contributing to negative health outcomes for patients with diabetic foot. Many complex factors related to patient's poor patient health-seeking behaviors, health system, and clinical characteristics of diabetic foot are responsible for these delays. Therefore, it is necessary to develop new strategies for standard referral practices and strengthen patient awareness of seeking care.

Abstract
INTRODUCTION Partial calcanectomy (PC) can be performed to treat chronic heel ulcers in patients with calcaneal osteomyelitis. Patients undergoing PC often have multiple comorbidities, limited mobility, and face high risk of major limb amputation. This study examined the extent of vascular diagnostic testing and interventions as well as long-term outcomes in patients undergoing PC. METHODS A retrospective analysis was performed on patients who underwent PC for non-healing calcaneal ulcer over a ten-year period. Demographics, comorbidities, vascular testing, and procedural data were recorded. Additional subgroup analysis was performed according to presence or absence of peripheral arterial disease (PAD). Primary outcomes were major limb amputation (above or below the knee) and mortality. Secondary outcomes included successful wound healing, time to complete wound healing, re-interventions, and change in ambulatory status. RESULTS A total of 157 patients underwent partial calcanectomies on 162 limbs. 78.3% of patients had diabetes mellitus and 47.8% were diagnosed with PAD. Ankle brachial index with pulse volume recording (ABI/PVR) was performed for 46.5% (73/157) of patients, arterial duplex in 44.6% (70/157), and 19.7% (31/157) had a computed tomography angiogram. Lower extremity revascularization was performed in 28.4% of limbs (46/162). Independent ambulatory status was reported in 40.1% prior to PC and decreased to 17.9% by the time of last recorded follow-up (p < .00001). Long-term amputation-free survival was significantly higher in patients without PAD at 7 years (78.4% vs 57.1%, p = .02). Multivariate logistic regression analysis demonstrated that PAD and end-stage renal disease (ESRD) increased the odds of major limb amputation (OR 3.5 and 2.8, respectively), whereas ESRD and adjuvant podiatric procedures were associated with increased mortality (OR 4.8 and 4.8, respectively). CONCLUSION Non-invasive vascular testing should be obtained in all patients undergoing PC, in order to stratify risk of amputation and identify candidates for revascularization. Over the long-term, patients undergoing PC face significant risk of prolonged wound healing, decline in ambulatory status, and major limb amputation.

Abstract
Background Diabetic foot ulcers (DFUs) are serious complications that induce a high risk of lower extremity amputations and mortality. Compared with the standard of care, few reports analyzed the outcome of surgical treatment mainly for diabetic toe deformities and ulcers. The aim of this study is to collate evidence on the outcomes of interphalangeal resection arthroplasty (IP-RA) in preventing and treating diabetic toe ulcers distal to the metatarsophalangeal joint. Methods A search strategy has been developed including electronic databases from inception. Only ulcers distal to the metatarsophalangeal joints were included. Noninfected and infected ulcers were also included at any toe location (dorsal/side/plantar). Outcomes were defined as healing rate, time to heal, ulcer recurrence, ulcer transfer, postintervention infection, wound dehiscence, and additional surgeries including amputation. Proportional meta-analysis was conducted for frequency outcomes. Results Six observational studies comprising 217 patients with 244 IP-RA procedures were included. The mean follow-up period was 23.4 ± 8.2 months. Weighted frequencies were as follows: healing rate (93.6%), ulcer recurrence frequency (4.3%), ulcer transfer frequency (15.4%), postoperative infection (10.5%), wound dehiscence (17.8%), revision surgery (5%), and amputation rate (3.4%). The mean healing time was 4.3 ± 1.8 weeks. Conclusion This review suggests that IP-RA is effective in preventing and treating diabetic toe deformities and ulcers with a modest rate of complications for this specific and often challenging clinical presentation.

Abstract
Diabetes related foot complications have become a major cause of morbidity and are implicated in most major and minor amputations globally. Approximately 50% of people with diabetes and a foot ulcer have peripheral artery disease (PAD) and the presence of PAD significantly increases the risk of adverse limb and cardiovascular events. The International Working Group on the Diabetic Foot (IWGDF) has published evidence based guidelines on the management and prevention of diabetes related foot complications since 1999. This guideline is an update of the 2019 IWGDF guideline on the diagnosis, prognosis and management of peripheral artery disease in people with diabetes mellitus and a foot ulcer. For this guideline the IWGDF, the European Society for Vascular Surgery and the Society for Vascular Surgery decided to collaborate to develop a consistent suite of recommendations relevant to clinicians in all countries. This guideline is based on three new systematic reviews. Using the Grading of Recommendations, Assessment, Development, and Evaluation framework clinically relevant questions were formulated, and the literature was systematically reviewed. After assessing the certainty of the evidence, recommendations were formulated which were weighed against the balance of benefits and harms, patient values, feasibility, acceptability, equity, resources required, and when available, costs. Through this process five recommendations were developed for diagnosing PAD in a person with diabetes, with and without a foot ulcer or gangrene. Five recommendations were developed for prognosis relating to estimating likelihood of healing and amputation outcomes in a person with diabetes and a foot ulcer or gangrene. Fifteen recommendations were developed related to PAD treatment encompassing prioritisation of people for revascularisation, the choice of a procedure and post-surgical care. In addition, the Writing Committee has highlighted key research questions where current evidence is lacking. The Writing Committee believes that following these recommendations will help healthcare professionals to provide better care and will reduce the burden of diabetes related foot complications.

Abstract
OBJECTIVE To develop a preliminary risk scoring system to predict the prognosis of patients with diabetic forefoot ulcers based on the severity of vasculopathy and infection, which are the major risk factors for amputation. METHODS Forefoot was defined as the distal part of the foot composed of the metatarsal bones and phalanges and associated soft tissue structures. The degree of vasculopathy was graded as V0, V1, or V2 according to transcutaneous partial oxygen tension values and toe pressure. The degree of infection was graded as I0, I1, or I2 according to tissue and bone biopsy culture results. The risk scores were calculated by adding the scores for the degree of vasculopathy and infection and ranged from 0 to 4. Wound healing outcomes were graded as healed without amputation, minor amputation, or major amputation. The authors evaluated wound healing outcomes according to risk scores. RESULTS As the risk score increased, the proportion of patients who underwent both major and minor amputations increased (P < .001). In the multivariate logistic analysis, the odds ratios of amputation also increased as the risk score increased. Patients with a risk score of 4 were 75- and 19-fold more likely to undergo major and minor amputations, respectively, than patients with a risk score of 0 (P = .006 and P < .001). CONCLUSIONS The risk score can be used as an indicator to predict the probability of amputation in patients with diabetic forefoot ulcers.

Abstract
BACKGROUND The dermal regeneration template (DRT), a tissue-engineered skin substitute composing a permanent dermal matrix and an upper temporary silicone layer that serves as the epidermis, has demonstrated efficacy in treating uncomplicated diabetic foot ulcers (DFUs). Our institution has obtained good outcomes with DRT in patients with more complicated DFUs. Because of its chronicity, the authors are working to identify a clinical target that anticipates delayed healing early in the treatment in addition to determining the risk factors linked to this endpoint to increase prevention. MATERIALS AND METHODS This retrospective single-center study analyzed patients with DFUs who underwent wound reconstruction using DRT between 2016 and 2021. The patients were categorized into poor or good graft-take groups based on their DRT status on the 21st day after the application. Their relationship with complete healing (CH) rate at day 180 was analyzed. Variables were collected for risk factors for poor graft take at day 21. Independent risk factors were identified after multivariable analysis. The causes of poor graft take were also reported. RESULTS This study examined 80 patients (38 and 42 patients in the poor and good graft-take groups, respectively). On day 180, the CH rate was 86.3% overall, but the poor graft-take group had a significantly lower CH rate (76.3 vs. 95.2%, P =0.021) than the good graft-take group. Our analysis identified four independent risk factors: transcutaneous oxygen pressure less than 30 mmHg (odds ratio, 154.14), off-loading device usage (0.03), diabetic neuropathy (6.51), and toe wound (0.20). The most frequent cause of poor graft take was infection (44.7%), followed by vascular compromise (21.1%) and hematoma (15.8%). CONCLUSION Our study introduces the novel concept of poor graft take at day 21 associated with delayed wound healing. Four independent risk factors were identified, which allows physicians to arrange interventions to mitigate their effects or select patients more precisely. DRT represents a viable alternative to address DFUs, even in complicated wounds. A subsequent split-thickness skin graft is not always necessary to achieve CH.

Abstract
Diabetic foot ulcer often leads to amputation, and both nutritional status and immune function have been associated with this process. We aimed to investigate the risk factors of diabetic ulcer-related amputation including the Controlling Nutritional Status score and neutrophil-to-lymphocyte ratio biomarker. We evaluated data from hospital in patients with diabetic foot ulcer, performing univariate and multivariate analyses to screen for high-risk factors and Kaplan-Meier analysis to correlate high-risk factors with amputation-free survival. Overall, 389 patients underwent 247 amputations over the follow-up period. After correction to relevant variables, we identified five independent risk factors for diabetic ulcer-related amputation: ulcer severity, ulcer site, peripheral arterial disease, neutrophil-to-lymphocyte ratio and nutritional status. Amputation-free survival was lower for the moderate-to-severe versus mild cases, for the plantar forefoot versus hindfoot location, for the concomitant peripheral artery disease versus without and in the high versus low neutrophil-to-lymphocyte ratio (all p < 0.01). The results showed that ulcer severity (p < 0.01), ulcer site (p < 0.01), peripheral artery disease (p < 0.01), neutrophil-to-lymphocyte ratio (p < 0.01) and Controlling Nutritional Status score (p < 0.05) were independent risk factors for amputation in diabetic foot ulcer patients and have predictive values for diabetic foot ulcer progression to amputation.

Abstract
This study investigated the effect of early rehabilitation on gait restoration, wound healing, and home discharge in patients with lower extremity (LE) chronic wounds. This multicenter, retrospective cohort study included 233 Japanese inpatients who received treatment for LE chronic wounds from April 2012 to March 2015. A multivariate analysis was conducted using outcomes of gait restoration, wound healing, and home discharge as dependent variables. Other survey items were used as independent variables. Early rehabilitation was extracted as an independent factor with gait restoration (hazard ratio [HR] 1.82, P < .01) and home discharge (HR 1.77, P < .001) as dependent factors by the stepwise method in Cox proportional-hazards regression analysis, but it was not extracted as an independent factor with wound healing as the dependent factor by the stepwise method as well as the forced entry method (P = .44). A significant relationship between the presence of gait restoration and home discharge was observed in the chi-square test (P<.001), and the duration from admission to gait restoration was significantly correlated to the duration from admission to home discharge (Pearson's product-moment correlation coefficient; r=.89, P<.0001). Early rehabilitation was a positive factor for gait restoration and home discharge in chronic LE wound patients.

Ann Vasc Surg 2023; 97:221-235. [PMID: 37659650 DOI: 10.1016/j.avsg.2023.08.005] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/23/2023] [Revised: 08/06/2023] [Accepted: 08/15/2023] [Indexed: 09/04/2023]
Abstract
BACKGROUND Objective measures of perfusion such as an ankle-brachial index (ABI) and toe pressure remain important in prognosticating wound healing. However, the use of ABI is limited in patients with incompressible vessels and toe pressure may not be comparable across patients. While a toe arm index (TAI) may be of value in this setting, its role as clinical indicator of perfusion for healing in patients with lower-extremity wounds has not been well established. METHODS A retrospective review was performed of all vascular patients with lower-extremity wounds that underwent peripheral vascular intervention between 2014-2019. Data regarding patient demographics, comorbidities, TAI, ABI, toe pressures, and the wound, ischemia, and foot infection (WIfI) score were collected. Associations between patient variables and wound healing at various time points were evaluated. RESULTS A total of 173 patients (67.7 ± 10.9 years; 71.1% male) were identified with lower-extremity wounds. Most patients underwent endovascular intervention (77.5%). Patients were followed for a median of 416 (IQR 129-900) days. Mean postoperative TAI was 0.35 ± 0.19 and mean WIfI score was 2.60 ± 1.17. Nine percent (15) of patients healed within 1 month, 44.8% (69) healed within 6 months, and 65.5% (97) healed within 1 year of revascularization without need for major amputation. Those that healed within 1 year without any major amputation did not differ from those that did not heal based on age, gender, race, comorbidities, periprocedural medications, or procedures performed. However, patients that healed without major amputation had a higher postoperative TAI (0.38 vs. 0.30, P = 0.02), higher toe pressure (53 vs. 40 mm Hg, P = 0.004), and lower WIfI score (2.26 vs. 3.12, P < 0.001). Patients that healed with 1 year without requiring any amputation had similar associations with postoperative TAI, toe pressure, and WIfI. Additionally, they were more likely to be White (P = 0.019) and have an open surgical procedure (P < 0.001) and less likely to have chronic kidney disease (P = 0.001) or diabetes (P = 0.008). A Youden index was calculated and identified a TAI value of 0.30 that optimized sensitivity and specificity for wound healing. The area under the curve for TAI as a predictor of wound healing was 0.62. CONCLUSIONS Higher postoperative TAI is associated with higher odds of wound healing without need for major amputation. Toe arm index is therefore a useful tool to identify patients with adequate arterial perfusion to heal lower-extremity wounds. However, the area under the curve is poor for TAI when used as a sole predictor of wound healing potential suggesting that TAI should be one of multiple factors to considered when prognosticating wound healing potential.

Abstract
Diabetes related foot complications have become a major cause of morbidity and are implicated in most major and minor amputations globally. Approximately 50% of people with diabetes and a foot ulcer have peripheral artery disease (PAD) and the presence of PAD significantly increases the risk of adverse limb and cardiovascular events. The International Working Group on the Diabetic Foot (IWGDF) has published evidence based guidelines on the management and prevention of diabetes related foot complications since 1999. This guideline is an update of the 2019 IWGDF guideline on the diagnosis, prognosis, and management of peripheral artery disease in people with diabetes mellitus and a foot ulcer. For this updated guideline, the IWGDF, the European Society for Vascular Surgery, and the Society for Vascular Surgery decided to collaborate to develop a consistent suite of recommendations relevant to clinicians in all countries. This guideline is based on three new systematic reviews. Using the Grading of Recommendations, Assessment, Development and Evaluation framework clinically relevant questions were formulated, and the literature was systematically reviewed. After assessing the certainty of the evidence, recommendations were formulated which were weighed against the balance of benefits and harms, patient values, feasibility, acceptability, equity, resources required, and when available, costs. Through this process five recommendations were developed for diagnosing PAD in a person with diabetes, with and without a foot ulcer or gangrene. Five recommendations were developed for prognosis relating to estimating likelihood of healing and amputation outcomes in a person with diabetes and a foot ulcer or gangrene. Fifteen recommendations were developed related to PAD treatment encompassing prioritisation of people for revascularisation, the choice of a procedure and post-surgical care. In addition, the Writing Committee has highlighted key research questions where current evidence is lacking. The Writing Committee believes that following these recommendations will help healthcare professionals to provide better care and will reduce the burden of diabetes related foot complications.

Abstract
The waterjet debridement is now a standard practice in contaminated or infected diabetic lower extremity wounds. The bacterial clearance of the waterjet debridement remains an important parameter that should be predicted in this application. This study aimed to investigate the waterjet in reducing the diabetic lower extremity wound contaminants. A retrospective cohort study was conducted. Patients' etiology and pathogen diagnosis were established as diabetic lower extremity contaminated wound. The high-power waterjet (Versajet™, Smith-Nephew) was used in the treatment group and conventional surgical methods were used in the control group. The bacteriological swab samples were collected before and after the debridement. The results of bacterial culture were analyzed. A total of 74 patients were included in our study, 40 patients in the treatment group and 34 in the control group. Patient characteristics were well matched. The preoperative bacteriological swab samples of the 2 groups showed no significant difference between each other with a P value of .1022. The culture result of postoperative bacteriological swab samples in the treatment group was significantly lower than control with a P value of .0099. The odds of bacterial clearance were greater in the treatment group than in the control group (odds ratio, 5.139; 95% confidence interval, 1.386-18.41). As demonstrated by this retrospective research, waterjet debridement reduced the bacterial load in the diabetic lower extremity contaminated wounds.

Int J Gen Med 2023; 16:3815-3827. [PMID: 37662508 PMCID: PMC10473433 DOI: 10.2147/ijgm.s427401] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/24/2023] [Accepted: 08/22/2023] [Indexed: 09/05/2023] Open
Abstract
Aim To explore the therapeutic efficacy of autologous wound edge-dotted full-thickness skin grafting in improving diabetic foot ulcer healing. Methods Sixty-three patients were divided into three groups: conventional wound therapy (CWT) (n = 23), platelet-rich plasma (PRP) (n = 20), and graft (n = 20). All participants were followed up for 12 weeks. The therapeutic efficacy of the three different wound treatment modalities was analyzed. Results After follow-up, 37 (58.7%) patients showed complete wound re-epithelialization, of which 10 (43.5%) occurred in the CWT group, 14 (70.0%) in the PRP group, and 13 (65.0%) in the graft group. Multivariate Cox analysis showed that the independent predictive factors for ulcer healing were different treatment modalities (graft: HR = 3.214, 95% CI=1.300-7.945, P < 0.05; platelet-rich plasma: HR = 3.075, 95% CI=1.320-7.161, P < 0.01), ABI (HR = 9.917, 95% CI=2.675-36.760, P < 0.01), and TcPO2 (HR = 1.040; 95% CI=1.005-1.076; P < 0.05). Stratified analysis showed that higher ABI in graft group or PRP group had higher wound healing rate (graft group: HR = 3.748, 95% CI=1.210-11.607, P < 0.05; PRP group: HR = 5.029, 95% CI=1.743-14.509, P < 0.05); higher TcPO2 in the graft group had higher wound healing rate (HR = 15.805, 95% CI=4.414-56.594, P < 0.01). Additionally, the wound healing time (P < 0.0167) and cumulative healing rate (P < 0.05) in both the PRP group and graft group were more advantageous. The graft group promotes wound re-epithelialization earlier and faster than in the CWT group and PRP group (P < 0.05). Meanwhile, the graft group had lower medical costs (P < 0.0167). Conclusion Autologous wound edge dotted full-thickness skin grafting has a higher cost-performance ratio than traditional diabetic foot ulcer wound care and is worthy of further clinical application.

Abstract
The prevalence of chronic wounds is increasing owing to the expanding population and the growing number of individuals suffering from diabetes. Such a chronic wound continues to be a significant healthcare burden for diabetic patients because it frequently carries a high chance of limb loss due to amputation and reduces survival as a result. Development of innovative wound dressing materials with the potential to stop bacterial infections and accelerate the process of tissue regeneration is needed to increase the effectiveness of diabetic wound healing. In the current study, a co-polymerization process based on a free radical reaction was used to create a hydrogel of polysaccharides blend graft acrylamide (PsB-g-Am). Starch, chitosan, and alginate make up the polysaccharides blend (PsB). The produced hydrogel's structure was characterized using FTIR spectroscopy. The antibacterial activities of silver nanoparticles synthesized through the green method using garlic bulb (Allium sativum) is reported. The silver nanoparticles' physical characteristics were examined using scanning electron microscopy, transmission electron microscopy analysis, and UV-visible spectroscopy and they were found to range in size from 50 to 100 nm. The agar well diffusion technique is used to investigate the antibacterial characteristics. Inclusion of silver nanoparticles in the hydrogels demonstrated concentration-dependent antibacterial behavior against Gram-negative Klebsiella pneumoniae and Gram-positive Staphylococcus aureus during antimicrobial testing of the hydrogels. When hydrogels were applied to diabetic mice, the system was examined for its healing abilities, and positive therapeutic results were obtained in as little as 14 days. Thus, it can be inferred that graft copolymer of chitosan-AgNPs hydrogels can promote healing in chronic wounds over time and can be utilized as an alternative to conventional therapies for chronic wounds (such as those brought on by diabetes) in mouse models.

Abstract
There is a high prevalence of digital deformities in diabetic patients, particularly claw toe, which can result in ulceration, often located at the tip of the toe. These lesions are challenging to off-load with conventional devices and frequently lead to infection and high amputation rates. Recent guidelines recommend considering flexor tenotomies to manage these ulcerations and prevent complications. This review, which analyzed 11 studies, aimed to assess the effect of flexor tenotomies on the healing and prevention of diabetic foot ulcers (DFUs) at the toe tip. Satisfactory results were found, with a healing rate of 92% to 100% and a mean healing time of 2-4 weeks. Few mild complications were observed, and the recurrence rate was very low. Transfer lesions were the most prevalent, but simultaneous tenotomy of all toes can eliminate this risk. Flexor tenotomies are a simple, effective, and safe procedure for the treatment and management of DFUs located at the apex of the toes and should be considered part of the standard of care for diabetic feet.

Abstract
OBJECTIVES To assess wound healing after simultaneous endovascular treatment (EVT) and minor forefoot amputation and identify the predictors of delayed wound healing in patients with chronic limb-threatening ischemia (CLTI) and bacterial infections of the wounds. METHODS In this single-center retrospective cohort study, we evaluated 79 consecutive limbs with tissue loss from 73 CLTI patients who underwent simultaneous EVT and minor forefoot amputation between November 2017 and May 2020. To estimate the rate of wound healing after the simultaneous procedure, we used the Kaplan-Meier method. To assess the association between baseline characteristics and delayed wound healing, we used the Cox proportional hazard model. RESULTS All patients who underwent the simultaneous procedure had ischemic wounds with bacterial infection. The rate of wound healing at 6 months reached 82%. The median time for wound healing was 76 days. According to multivariable analysis, Lisfranc/Chopart amputation (hazard ratio (HR) 2.46, 95% confidence interval (CI) 1.09-6.60), absence of above-the-knee (ATK) occlusive lesions (HR 1.89, 95% CI 1.04-3.45), and poor below-the-ankle (BTA) runoff (HR 1.77, 95% CI 1.01-3.11) were independent predictors of delayed wound healing. CONCLUSION Lisfranc/Chopart amputation, absence of ATK occlusive lesions, and poor BTA runoff were independent predictors of delayed wound healing after simultaneous EVT and minor forefoot amputation in patients with CLTI and bacterial infections of the wound.

Abstract
Leg ulcers are a common and often serious problem in older adults. Underlying conditions that increase risk include age-related increases in chronic venous insufficiency, peripheral artery disease, connective tissue and autoimmune conditions, reduced mobility, and diabetes mellitus (DM). Geriatric patients have a higher risk of multiple wound-related complications including infection, cellulitis, ischemia, and gangrene, any of which may lead to further complications including amputation. The very presence of these lower extremity ulcers in the elderly negatively impacts their quality of life and ability to function. Understanding and early identification of the underlying conditions and wound features are important for effective ulcer healing and complication mitigation. This targeted review focuses on the three most common types of lower extremity ulcers: venous, arterial, and neuropathic. The goal of this paper is to characterize and discuss the general and specific aspects of these lower extremity ulcers and their relevancy and impact on the geriatric population. The top five main results of this study can be summarized as follows. (1) Venous ulcers, caused by inflammatory processes secondary to venous reflux and hypertension, are the most common chronic leg ulcer in the geriatric population. (2) Arterial-ischemic ulcers are mainly due to lower extremity vascular disease, which itself tends to increase with increasing age setting the stage for an age-related increase in leg ulcers. (3) Persons with DM are at increased risk of developing foot ulcers mainly due to neuropathy and localized ischemia, both of which tend to increase with advancing age. (4) In geriatric patients with leg ulcers, it is important to rule out vasculitis or malignancy as causes. (5) Treatment is best made on a case-by-case basis, considering the patient's underlying condition, comorbidities, overall health status, and life expectancy.

Abstract
Background Diabetes mellitus is a chronic disease that is associated with increased morbidity and mortality. Unfortunately, foot ulcers and amputations due to diabetes are very common in developing countries. The purpose of this study was to characterize the clinical presentation of diabetic foot ulcer (DFU) infections, isolate the causative agent, and analyze the biofilm formation and distribution of biofilm-related genes among isolated Staphylococci. Material and Methods The study included 100 diabetic patients suffering from DFUs attending Assiut University Hospital. Swabs were collected and antimicrobial susceptibility testing of the isolates was performed. Biofilm formation was tested phenotypically among staphylococcal isolates and the frequency of different biofilm genes was analyzed by PCR. Clinical presentations of diabetic foot ulcers were correlated with bacterial genetic characteristics. Spa types were determined using DNA Gear-a software. Results Microbiological analysis showed that 94/100 of the DFUs were positive for bacterial growth. The majority of infections were polymicrobial (54%, n=54/100). Staphylococci were the most commonly detected organisms, of which S. aureus represented 37.5% (n=24/64), S. haemolyticus 23.4% (n=15/64), S. epidermidis 34.3% (n=22/64) and other CNS 4.7% (n=3/64). Interestingly, co-infection with more than one species of Staphylococci was observed in 17.1% (n=11/64) of samples. A high level of antibiotic resistance was observed, where 78.1% (n=50/64) of Staphylococci spp were multidrug-resistant (MDR). Phenotypic detection showed that all isolated Staphylococci were biofilm-formers with different grades. Analysis of biofilm-forming genes among Staphylococci showed that the most predominant genes were icaD, spa, and bap. Isolates with a higher number of biofilm-related genes were associated with strong biofilm formation. Sequencing of the spa gene in S. aureus showed that our isolates represent a collection of 17 different spa types. Conclusion The majority of DFUs in our hospital are polymicrobial. Staphylococci other than S.aureus are major contributors to infected DFUs. MDR and biofilm formation are marked among isolates, which is paralleled by the presence of different categories of virulence-related genes. All severely infected wounds were associated with either strong or intermediate biofilm formers. The severity of DFU is directly related to the number of biofilm genes.

Impact of case-mix adjustment on observed variation in the healing of diabetic foot ulcers at 12 weeks using data from the National Diabetes Foot Care Audit of England and Wales: A cohort study. Diabet Med 2023; 40:e14959. [PMID: 36114737 DOI: 10.1111/dme.14959] [Citation(s) in RCA: 4] [Impact Index Per Article: 4.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 02/28/2022] [Revised: 07/05/2022] [Accepted: 08/18/2022] [Indexed: 11/29/2022]
Abstract
AIM This cohort study investigates the extent to which variation in ulcer healing between services can be explained by demographic and clinical characteristics. METHODS The National Diabetes Foot Care Audit collated data on people with diabetic foot ulcers presenting to specialist services in England and Wales between July 2014 and March 2018. Logistic regression models were created to describe associations between risk factors and a person being alive and ulcer-free 12 weeks from presentation, and to investigate whether variation between 120 participating services persisted after risk factor adjustment. RESULTS Of 27,030 people with valid outcome data, 12,925 (47.8%) were alive and ulcer-free at 12 weeks, 13,745 (50.9%) had an unhealed ulcer and 360 had died (1.3%). Factors associated with worse outcome were male sex, more severe ulcers, history of cardiac or renal disease and a longer time between first presentation to a non-specialist healthcare professional and first expert assessment. After adjustment for these factors, four services (3.3%) were more than 3SD above and seven services (5.8%) were more than 3SD below the national mean for proportions that were alive and ulcer-free at follow-up. CONCLUSIONS/INTERPRETATIONS Variation in the healing of diabetic foot ulcers between specialist services in England and Wales persisted after adjusting for demographic characteristics, ulcer severity, smoking, body mass index and co-morbidities. We conclude that other factors contribute to variation in healing of diabetic foot ulcers and include the time to specialist assessment.

Abstract
Diabetic foot ulceration is a devastating complication of diabetes that is associated with infection, amputation, and death, and is affecting increasing numbers of patients with diabetes mellitus. The pathogenesis of foot ulcers is complex, and different factors play major roles in different stages. The refractory nature of foot ulcer is reflected in that even after healing there is still a high recurrence rate and amputation rate, which means that management and nursing plans need to be considered carefully. The importance of establishment of measures for prevention and management of DFU has been emphasized. Therefore, a validated and appropriate DFU classification matching the progression is necessary for clinical diagnosis and management. In the first part of this review, we list several commonly used classification systems and describe their application conditions, scope, strengths, and limitations; in the second part, we briefly introduce the common risk factors for DFU, such as neuropathy, peripheral artery disease, foot deformities, diabetes complications, and obesity. Focusing on the relationship between the risk factors and DFU progression may facilitate prevention and timely management; in the last part, we emphasize the importance of preventive education, characterize several of the most frequently used management approaches, including glycemic control, exercise, offloading, and infection control, and call for taking into account and weighing the quality of life during the formulation of treatment plans. Multidisciplinary intervention and management of diabetic foot ulcers (DFUs) based on the effective and systematic combination of these three components will contribute to the prevention and treatment of DFUs, and improve their prognosis.

Abstract
AIMS Diabetic foot ulcers (DFU) have a complex multifactorial pathophysiology. It is crucial to identify essential prognostic variables to streamline therapeutic actions and quality-of-care audits. Although SINBAD and University of Texas (UT), the most frequently used prognostic classification systems, were prospectively validated, not all individual parameters were shown to have consistent associations with healing. In this study, we used a bottom-up approach relying on robust methods to identify independent predictors of DFU healing. METHODS 1,664 DFU patients were included by 34 Belgian diabetic foot clinics (DFCs). Twenty-one patient- and foot-related characteristics were recorded at presentation. Predictors of healing were identified using multivariable Cox proportional hazard regression. Multivariable models were built using backward regression with multiple imputation of missing values and bootstrapping. RESULTS Five essential independent variables were identified: presentation delay, history of minor amputation, ulcer location, surface area and ischemia. This 5 variable-model showed a better performance compared to models based on existing classification systems. CONCLUSIONS A bottom-up approach was used to build a prognostic classification for DFU healing based on large databases. It offers new insights and allows to tailor the classification to certain clinical settings. These 5 parameters could be used as a 'precision classification' for specialized DFCs.

Abstract
Background and aims Diabetic foot ulcer location is a known independent predictor for cure with a better healing gradient proximal to distal. Although advanced age is one of the main factors associated with greater diabetic foot ulcer severity, there are no studies evaluating diabetic foot ulcer location specifically in the elderly population in an outpatient setting. This study evaluated diabetic foot ulcer location and age-group interactions in diabetic foot presentation. Methods A retrospective cohort study including adult patients with diabetic foot ulcers observed on their first visit to our center's Diabetic Foot Unit in 2018, divided into younger adults (YA) (18 to 64 years) and older adults (OA) (≥65 years). Results A total of 435 patients were included in the study with 159 (36.6%) in the YA, and 276 (63.4%) in the OA group. Neuro-ischemic diabetic foot ulcers were more frequent in the OA group (71.4% vs 43.4%, p<0.001). The number of patients with a history of diabetic foot ulcers was lower in the OA group (18.1% vs 25.2%, p=0.03). A smaller proportion of forefoot diabetic foot ulcers (74.9% vs 86.2%, p=0.007) and plantar location diabetic foot ulcers (9.4% vs 24.5%, p<0.001) occurred in the OA group. By univariate logistic regression analysis, we found two associations with older age: proximal (odds ratio (OR) 2.09 (1.23-3.53), p=0.006), and non-plantar (OR 3.13 (1.82-5.37), p<0.001) diabetic foot ulcer location. After adjusting for potential confounders in a multivariate analysis, older age lost the association to more proximal (OR 1.72 (0.94-3.15), p=0.081) and non-plantar (OR 1.78 (0.83-3.77), p=0.133) diabetic foot ulcer location. Conclusions There are essential age differences in diabetic foot ulcer presentation. The OA group more frequently presents neuro-ischemic diabetic foot ulcers with more proximal and non-plantar locations.

Abstract
Background: To assess long-term clinical outcomes of patients who underwent isolated versus several percutaneous flexor tenotomies for the treatment of toe deformities and previous diabetic foot ulcers; Methods: Twenty-three patients (mean age 66.26 ± 11.20, years) who underwent prophylactic percutaneous flexor tenotomies secondary to tip-toe ulcers participated in this 1-year prospective study. The study was stratified into two groups for analyses: (1) isolated tenotomies patients, and (2) several tenotomies patients (two or more tenotomies). Outcome measures were toe reulceration and recurrence, minor lesions, digital deformities, and peak plantar pressure (PPP—N/cm2) and pressure/time Integral (PTI—N/cm2/s) in the hallux and minor toes after a 1-year follow-up period; Results: Patients with isolated tenotomies (n = 11, 35.48%) showed a higher rate of reulceration (n = 8, 72.7%, p < 0.001) in the adjacent toes, additionally, we found more prevalence of hyperkeratosis (n = 11, 100%), minor lesions (n = 9, 81%), and claw toes (n = 11, 100%) (p < 0.001). In several tenotomies patients (n = 20, 64.52%), we found a higher rate of floating toes (n = 16, 80%) in comparison with isolated tenotomies patients (p < 0.001). PPP and PTI in the non-tenotomy toes were higher in the group of patients who underwent isolated tenotomies (p < 0.001); Conclusions: Patients who underwent several tenotomies had better clinical outcomes after a 1-year follow-up period compared to isolated tenotomies.

Abstract
The study aimed to evaluate the effectiveness of the use of sucrose octasulfate impregnated dressing (TLC-NOSF [Technology Lipido-Colloid-Nano-OligoSaccharide Factor]) in the management of persons with neuro-ischaemic heel diabetic foot ulcers (DFUs). Consecutive patients who referred for an active non-infected neuro-ischaemic heel DFU belonging to grade IC (superficial) or IIC (deep to tendons, muscle or capsule) according to Texas University Classification were included. All patients were managed by a pre-set limb salvage protocol in the respect of International guidelines and the TLC-NOSF dressing was used as primary and specific dressing. Patients were evaluated any 2 to 4 weeks until wound healing or different outcomes. Primary outcome was the rate of complete wound healing after 24 weeks of follow-up. The secondary outcomes assessed the healing time, the rate of wound regression, the re-ulceration in the case of complete healing and the safety. Thirty patients were included. The mean age was 67 ± 11 years, 17 (56.7%) were male, all of them were affected by type 2 diabetes with a mean duration of 18 ± 7 years. Twenty patients (66.7%) showed deep ulcers (grade 2 of Texas University Classification); the mean TcPO2 at the inclusion was 42 ± 7 mm Hg. Twenty-two patients (73.3%) healed by Week 24. The mean time of healing was 84 ± 32 days, 2 (6.7%) patients had ulcer relapse after healing, 28 (93.3%) had wound regression >50%, 2 (6.7%) had mild infection, 1 (3.3%) reported major amputation. No serious adverse events related to TLC-NOSF dressing or local reactions were reported. This current study showed the potential benefit of sucrose octasulfate for treating neuro-ischaemic heel DFUs in addition to the standard of care.

Abstract
AIMS To investigate factors independently associated with time-to-(being)-ulcer-free, time-varying effects and predict adjusted ulcer-free probabilities, in a large prospective cohort with diabetes-related foot ulcers (DFU) followed-up for 24 months. METHODS Patients presenting with DFU(s) to 65 Diabetic Foot Services across Queensland, Australia, between July-2011 and December-2017 were included. Demographic, comorbidity, limb, ulcer, and treatment factors were captured at presentation. Patients were followed-up until ulcer-free (all DFU(s) healed), amputation, death or two years. Factors associated with time-to-ulcer-free were investigated using both Cox proportional hazards and flexible parametric survival models to explore time-varying effects and plot predicted adjusted ulcer-free probability graphs. RESULTS Of 4,709 included patients (median age 63 years, 69.5% male), median time-to-ulcer-free was 112 days (IQR:40->730), with 68.4% ulcer-free within two years. Factors independently associated with longer time-to-ulcer-free were each year of age younger than 60 years, living in a regional or remote area, smoking, neuropathy, peripheral artery disease (PAD), ulcer size >1 cm2, deep ulcer and mild infection (all p < 0.05). Time-varying effects were found for PAD and ulcer size limiting their association to six months only. Shorter time-to-ulcer-free was associated with recent DFU treatment by a podiatrist and receiving knee-high offloading treatment (both p < 0.05). Predicted adjusted ulcer-free probability graphs reported largest differences in time-to-ulcer-free over 24-months for geographical remoteness and PAD factors. CONCLUSIONS Multiple factors predicted longer and shorter time-to-ulcer-free in people presenting with DFUs. Considering these factors, their time-varying effects and adjusted ulcer-free probability graphs, should aid the prediction of the likely time-to-(being)-ulcer-free for DFU patients.

Abstract
BACKGROUND Recurrence of high-risk diabetic feet, after wound, healing is a common challenge among diabetic patients. Continuous use of an offloading device significantly prevents recurrence of high-risk diabetic feet, although patient adherence is imperative to ensuring this therapy's clinical efficacy. In this study, we explored clinical outcomes of patients with a high-risk diabetic foot who had been prescribed with custom-molded offloading footwear under different adherence conditions. METHODS A total of 48 patients (17 females and 31 males) with high-risk diabetic feet, who had been with prescribed offloading footwear in 13 medical centers across 4 cities, were enrolled in the current study. The patients were assigned into either continuous offloading therapy (COT, n = 31) or interrupted offloading therapy (IOT, n = 17) groups, according to their adherence to the therapy. All patients were followed up monthly, and differences in recurrence, amputation, and deaths between the groups were analyzed at 4 months after therapy. RESULTS Forty-eight patients met our inclusion criteria and were therefore included in the final analysis. Among them, 31 were stratified into the COT group and adhered to offloading therapy throughout the study period, whereas 17 were grouped as IOT and exhibited interrupted adherence to offloading therapy. We found statistically significant differences in recurrence rates (0 vs 38.46%, p < 0.01), amputation (0 vs 11.76%, p < 0.01), and deaths (0% vs 5.88%, p < 0.01) between the groups during follow-up. CONCLUSION Patients' adherence is imperative to efficacy of custom-molded offloading footwear during treatment of high-risk diabetic foot. Further studies are needed to elucidate the role of improved design of the offloading device and the need for enhanced patient education for improved adherence.

Abstract
OBJECTIVE To identify and determine patient- and ulcer-related factors associated with healing outcomes within 3 months for patients with diabetic foot ulcer (DFU) in a multiethnic primary care sample. METHODS Retrospective data were collected over 3 months from 520 primary care patients with a DFU between April 1, 2016 and March 31, 2017. Multivariable prevalence ratios (PRs) were calculated using Poisson regression to find associations between patient- and ulcer-related factors and healing outcomes. RESULTS Most patients were male (66%) and Chinese (49.8%) and had a diabetes mellitus duration longer than 5 years (81.8%). Toe ulcers (64%) were most common. Healing occurred for 33.9% of participants; 19.1% and 1.5% underwent minor and major amputation, respectively. Wound sizes between 1 and 10 cm2 (PR, 0.61; 95% confidence interval [CI], 0.46-0.76; P < .001) and over 10 cm2 (PR, 0.55; 95% CI, 0.33-0.76; P = .003), ulcer duration 6 months or longer (PR, 0.36; 95% CI, 0.19-0.53; P < .001), ischemic ulcers (PR, 0.54; 95% CI, 0.22-0.86; P = .044), and neuroischemic ulcers (PR, 0.73; 95% CI, 0.53-0.93; P = .027) were negatively associated with healing outcomes. Women were more likely to experience healing (PR, 1.18; 95% CI, 0.91-1.45; P = .157). CONCLUSIONS Ulcer healing varied by sex and was affected by wound size, wound duration, and ischemic etiology, regardless of ethnicity. Prompt attention to these risk factors may reduce healing time. Further studies are warranted to elucidate the mechanism underlying sex differences in association with DFU healing.

Abstract
BACKGROUND Irremovable total contact casts (TCCs) are the gold standard to offload diabetic foot ulcers (DFUs) and to immobilize feet with active Charcot neuro-osteoarthropathy (CN). They do not allow checks of the foot and are contraindicated in people with peripheral arterial disease (PAD). Frequently, removable TCCs and other removable devices are used because they allow wound care, modifications of the inner surface of the cast, and checks of the foot. The authors propose TCCs with ventral windows (VW-TCCs) whenever patients with high-risk conditions show poor adherence to wearing a removable cast all the time and access to the foot is necessary. METHODS This retrospective study compares treatments with bivalved, removable TCCs applied prior to the introduction of the novel design (from 1 January 2016 to 1 July 2017, "c") to treatments in the following period (t) with both bivalved removable TCCs and VW-TCCs in use. RESULTS Forty-five treatments after introduction (17 with the VW-TCC) showed a 52.8% lower median time to reach remission of the DFS than 41 controls (128/267 days, log-rank test P = .013). Reasons given for not using the novel design were: sufficient offloading with a removable TCC (16), patient preference (six), anatomical conditions (two), casts applied as a service for other facilities (three), and calf ulcers (one). Adverse effects from both designs were uncommon and not severe. CONCLUSIONS VW-TCCs combine advantages of both removable and irremovable TCCs. Complications do not limit the use, even in patients with PAD.

Abstract
INTRODUCTION We previously demonstrated in both a longitudinal study and in meta-analysis (pooled relative-risk RR, 2.45) that all-cause mortality is significantly higher in people with diabetes foot ulceration (DFU) than with those without a foot ulcer. In this prospective study, we looked at the factors linked to mortality after presentation to podiatry with DFU. METHODS Ninety-eight individuals recruited consecutively from the Salford Royal Hospital Multidisciplinary Foot Clinic in Spring 2016 were followed up for up to 48 months. Data concerning health outcomes were extracted from the electronic patient record (EPR). RESULTS Seventeen people (17) had type 1 diabetes mellitus, and 81 had type 2 diabetes mellitus. Thirty-one were women. The mean age (range) was 63.6 (28-90) years with maximum diabetes duration 45 years. Mean HbA1c was 72 (95% CI: 67-77) mmol/mol; 97% had neuropathy (International Working Group on the Diabetic Foot (IWGDF) monofilament); 62% had vascular insufficiency (Doppler studies); 69% of ulcers were forefoot, and 23% of ulcers were hind foot in location. Forty of 98 (40%) patients died in follow-up with 27% of death certificates including sepsis (not foot-related) and 35% renal failure as cause of death. Multivariate regression analysis indicated a 6.3 (95% CI: 3.9-8.1) fold increased risk of death with hind foot ulcer, independent of age/BMI/gender/HbA1c/eGFR/total cholesterol level. CONCLUSION This prospective study has indicated a very high long-term mortality rate in individuals with DFU, greater for those with a hind foot ulcer and shown a close relation between risk of sepsis/renal failure and DFU mortality, highlighting again the importance of addressing all risk factors as soon as people present with a foot ulcer.

Abstract
OBJECTIVE to develop a mid-range theory for nursing diagnosis ineffective peripheral tissue perfusion in patients with diabetic foot. METHOD the theory construction was carried out in six stages: approach definition; theoretical-conceptual model definition; definition of the main concepts; pictogram development; construction of propositions and establishment of causal relationships evidence for practice. RESULTS twelve etiological factors and 22 clinical indicators were included in the theory, some of which were not listed in NANDA International (Inc.) and others were adapted to better characterize patients with diabetic foot. A pictogram was constructed and eight propositions were established to verify causal relationships and evidence for practice. CONCLUSION medium-range theory made it possible to broaden the concepts and demonstrate the causal relationships between the elements of ineffective peripheral tissue perfusion, providing subsidies to minimize gaps in knowledge and assist clinical nursing practice.

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
Non-offloaded diabetic heel ulcers and the wound dressings used to treat them may be subjected to considerable bodyweight forces. A novel robotic foot phantom with a diabetic heel ulcer was designed and constructed to test the combined performances of applied primary and secondary dressings, in simulated non-offloaded (standing) and offloaded (supine) postures. We specifically compared the performances of the primary Exufiber dressing (Mölnlycke Health Care) combined with the secondary Mepilex Border Flex dressing (Mölnlycke) against a corresponding pair from an alternative manufacturer. Fluid retention and distribution between the primary and secondary dressings of each pair were determined using weight tests, and mechanical strength of the primary dressings was further measured postsimulated use through tensile testing. The Exufiber and Mepilex Border Flex pair performed similarly in the two simulated postures (retention = ~97%), whereas the comparator pair exhibited a 13%-decrease in retention for a supine to standing transition. Furthermore, the Exufiber dressing delivered up to 2-times more fluid to its paired secondary dressing and endured 1.7-times greater strain energy than the corresponding primary dressing before failure occurred. The present robotic foot phantom and associated methods are versatile and suitable for testing any dressing, in consideration of the relevant clinical factors and practice.

Abstract
Chronic foot ulcers have extensive consequences for diabetic patients' quality of life and increase risks of amputation and death. The aim of this trial was to assess the feasibility of conducting a larger clinical trial to evaluate the clinical effect of inforatio technique on healing of diabetic foot ulcers (DFUs). Inforatio technique is a novel minimal invasive procedure where small cuts are made on wound beds with punch biopsy tools. This study was a feasibility trial conducted at an outpatient wound care clinic at Zealand University Hospital. Twelve patients with DFUs were included. During a 90-day follow-up, participants visited the clinic 5 times and received inforatio technique twice. Feasibility was assessed with regard to recruitment, acceptability, burden, benefits, protocol adherence, and adverse events. The recruitment rate was 1 patient per eighth day (95% confidence interval [CI] = [4th-13th]), and the retention rate was 100% (95% CI = [74-100]). During follow-up, healing was observed for 4 ulcers (33%, 95% CI = [10-65]) with a mean time for healing of 59 days (range, 22-89) (95% CI = [5-113]). Five ulcers had a reduction of wound area and 3 ulcers had an increase in area from baseline to 90-day follow-up. No temporal relationship was found between inforatio application and wound area increase. There were no patient-reported harmful effects and no adverse events with probable relation to inforatio technique. Patient acceptability and participant adherence were promising. Thus, a larger clinical trial for evaluating the clinical effect of inforatio technique is considered feasible to conduct.

Abstract
BACKGROUND Heel ulcers in patients with peripheral neuropathy and diabetes pose a significant challenge to treating physicians. Infection spreading to the os calcis is associated with a poor prognosis. There is no consensus on which method of surgical treatments results in better outcomes. The aim of this study was to assess patients' survival, rate of ulcer healing following surgical treatment, along with limb salvage rate, time taken for healing, ulcer recurrence and patients' functional outcome after healing. METHODS We studied 29 patients (20 men, 9 women) presenting with diabetic neuropathic heel ulcers (30 feet) and no critical limb ischemia, were managed surgically in our unit and followed-up for a minimum of 12 months. We assessed their clinical and functional outcomes within a mean follow-up period of 28 months (12-83). RESULTS 11 out of 29 patients died (38%) with mean duration of post op survival being 31months (range 4-70). 14 ulcers (50%) healed fully within a mean of 360 days (131-1676). Limb salvage was achieved in 29 feet (97%). Only 5 out of 17 patients with diabetic nephropathy (p value 0.016) and 9 out of 24 ulcers with calcaneal osteomyelitis (p value 0.044) achieved full ulcer healing. Ulcer recurrence rate was 36% (5/14) within 12 months of achieving ulcer healing. Six patients were able to return to independent walking in surgical shoes while 11 patients were mobilising using either a crutch or frame. CONCLUSION While excellent limb salvage can be anticipated from the outcome of surgically managed infected heel ulcers in patients with diabetes, complete healing can still be slow and unpredictable. Significant medical co-morbidities in these patients make them vulnerable to medium-term post-operative complication and survival.

Abstract
Diabetic patients are at increased risk of developing foot ulcers which may cause bone infections associated with a high probability of both amputation and mortality. Therefore, prompt diagnosis and adequate treatment are of key importance. In our Diabetic Foot Unit, effective multidisciplinary treatment of osteomyelitis secondary to diabetes involves the application of a gentamicin-eluting calcium sulphate/hydroxyapatite bone graft substitute to fill residual bone voids after debridement. The data of all patients treated with the gentamicin-eluting calcium sulphate/hydroxyapatite bone graft substitute for diabetic foot infections with ulcer formation and osteomyelitis at metatarsals, calcaneus and hindfoot at our institute from July 2013 to September 2016 were retrospectively collected and evaluated. A total of 35 patients were included in this retrospective single-arm case series and were either continuously followed up for at least one year or until healing was confirmed. Nineteen lesions affected the distal row of tarsus/talus, ten the calcaneus and a further six were located at the metatarsals. While all of the metatarsal lesions had healed at 1-year follow-up, the healing rate in the hindfoot region was lower with 62.5% at the calcaneus and 72.2% at the distal tarsus and talus at 12 months, respectively. The overall cure rate for ulcerous bone infection was 81.3%. In two calcaneal lesions (25%) and two lesions of distal tarsus/talus (11.1%) amputation was considered clinically necessary. Promising results were achieved in the treatment of diabetic foot infections with soft tissue ulcers by a multidisciplinary approach involving extensive debridement followed by adequate dead space management with a resorbable gentamicin-eluting bone graft substitute.

Abstract
BACKGROUND The utility of dermal regeneration templates for treating high-risk diabetic foot wounds is unclear. The authors report wound healing and major amputation outcomes among a cohort of diabetic patients with complex diabetic foot wounds treated in a multidisciplinary setting. METHODS All patients with complex diabetic foot wounds treated with a dermal regeneration template (March of 2013 to February of 2019) were captured in a prospective institutional database. Wound severity was classified according to the Society for Vascular Surgery Wound, Ischemia, and foot Infection (WIfI) classification system to determine limb salvage prognosis at baseline. Wound healing and major amputation rates were reported using Kaplan-Meier analyses. A stepwise Cox proportional hazards model was used to identify independent characteristics associated with wound healing. RESULTS Eighty-five patients with 107 complex diabetic foot wounds were treated (mean age, 61.2 ± 3.3 years; 63.5 percent male and 61.2 percent African American). Most diabetic foot wounds were high-risk (wound, ischemia, and foot infection stage 3 or 4, 93.5 percent), corresponding to a predicted 25 to 50 percent risk of major amputation at 1 year. Dermal regeneration template use resulted in successful wound granulation in 66.7 percent of cases, with a mean time to complete wound healing of 198 ± 18 days. Twelve- and 18-month wound healing rates were 79.0 ± 5.0 percent and 93.0 ± 3.3 percent, respectively. Major amputation was required in 11.2 percent of patients. Independent predictors of poor wound healing included lack of bone involvement, higher WIfI stage, and prior dermal regeneration template failure. CONCLUSION Application of a dermal regeneration template to complex diabetic foot wounds at high risk for major amputation results in good wound healing and excellent limb salvage outcomes among diabetic patients treated in a multidisciplinary setting. CLINICAL QUESTION/LEVEL OF EVIDENCE Therapeutic, IV.

Abstract
AIM To evaluate clinical outcomes in patients who underwent diabetic foot surgery (DFS) managed directly by diabetologists in a third-level Centre over 15-year. METHODS We retrospectively evaluated 1.857 patients affected by diabetic foot (Age 67.1 ± 12.3 yrs, diabetes duration 19.2 ± 9.8 yrs, HbA1c 8.1 ± 2.0%) treated in our Department between 2001 and 2015 and divided them into 3 groups: Group 1, treated between 2001 and 2005 (448 pts), group 2, between 2006 and 2010 (540 pts) and Group 3, between 2011 and 2015 (869 pts). Main clinical outcomes [peripheral revascularization rate (PR), healing rate (HR), healing time (HT), recurrences after healing (R), major amputation (MA) and death (D) rates] were compared between groups. RESULTS The overall outcomes of our cohort were: HR 81.6% (HT 143 ± 54 days), PR 84.8%, MA 4.9% and D 27.9%. There were no differences in clinical characteristics, except for age, higher (p < 0.05) in Group 3 (70.6 ± 14.7 yrs) than in Groups 1 (64.4 ± 11.6 yrs) and 2 (65.1 ± 11.2 yrs). No differences emerged when comparing HR and MA; HT was shorter (p < 0.05) in group 3 (104 ± 44 days) than in Group 2 (169 ± 72 days) and 1 (235 ± 67 days). D was higher (p < 0.05) in Group 3 (43.8%) than in Group 1 (23.1%) and 2 (28.1%). PR was 19.4% in Group 1, 28.1% in Group 2 and 53.8% in Group 3 (p < 0.05). CONCLUSIONS Despite the increasing age and complexity of patients our data show improvement of outcomes throughout 15 years, probably due to better surgical techniques, more aggressive medical therapy and more effective treatment of critical limb ischemia.

Abstract
OBJECTIVE Few studies adequately evaluate the impact of wound location on patient outcomes after lower extremity revascularization. Consequently, we evaluated the relationship between lower extremity wound location and long-term outcomes. METHODS We reviewed all patients at our institution undergoing any first-time open surgical bypass or percutaneous transluminal angioplasty with or without stenting for tissue loss between 2005 and 2014. We categorized wounds into three distinct groups: forefoot (ie, toes and metatarsal heads), midfoot (ie, dorsal, plantar, lateral, medial surfaces excluding toes, metatarsal heads, or heel), and heel. Limbs with multiple wounds were excluded from analyses. We compared rates of perioperative complications, wound healing, reintervention, limb salvage, amputation-free survival, and survival using χ2, Kaplan-Meier, and Cox regression analyses. RESULTS Of 2869 infrainguinal revascularizations from 2005 to 2014, 1126 underwent a first-time revascularization for tissue loss, of which 253 patients had multiple wounds, 197 had wounds proximal to the ankle, 100 had unreliable wound information, and 576 (forefoot, n = 397; midfoot, n = 61; heel, n = 118) fit our criteria and had a single foot wound with reliable information regarding wound specifics. Patients with forefoot, midfoot, and heel wounds had similar rates of coronary artery disease, hypertension, diabetes, and smoking history (all P > .05). Conversely, there were significant differences in patient age (71 vs 69 vs 70 years), prevalence of gangrene (41% vs 5% vs 21%), and dialysis dependence (18% vs 17% vs 30%) (all P < .05). There were no statistically significant differences in perioperative mortality (1.3% vs 4.9% vs 4.2%; P = .06) or postoperative complications among the three groups. Between forefoot, midfoot, and heel wounds, there were significant differences in unadjusted 6-month rates of complete wound healing (69% vs 64% vs 53%), 3-year rates of amputation-free survival (54% vs 57% vs 35%), and survival (61% vs 72% vs 41%) (all P < .05). After adjustment, compared with forefoot wounds, heel wounds were associated with higher rates of incomplete 6-month wound healing (hazard ratio [HR], 1.6; 95% confidence interval [CI], 1.1-2.]), major amputation or mortality (HR, 1.7; 95% CI, 1.1-2.7), and all-cause mortality (HR, 1.8; 95% CI, 1.1-3.0), but not major amputation alone (HR, 2.1; 95% CI, 0.9-4.5). In open surgical bypass-first patients, heel wounds were solely associated with an increased risk of all-cause mortality (HR, 1.7; 95% CI, 1.1-2.8), whereas heel wounds in percutaneous transluminal angioplasty-first patients were associated with an increased risk of incomplete wound healing (HR, 2.2; 95% CI, 1.3-3.7), major amputation or mortality (HR, 2.3; 95% CI, 1.1-5.4), and all-cause mortality (HR, 2.8; 95% CI, 1.1-7.2). CONCLUSIONS Heel wounds confer considerably higher short- and long-term morbidity and mortality compared with midfoot or forefoot wounds in patients undergoing any first-time lower extremity revascularization.

Abstract
BACKGROUND Limited scientific evidence for prevention and treatment of diabetic foot ulcers in elderly with comorbidities. AIM To explore patient-related factors and outcomes in patients ≥75 years with diabetes and a foot ulcer. METHOD Sub-analysis of consecutively presenting patients ≥75 years (N = 1008) from a previous study on 2,480 patients with diabetic foot ulcer treated in a multidisciplinary system until healing. Patient characteristics: age - 81(75-96); diabetes type 2-98.7%; male/female - 49/51%; living with a spouse - 47%; nursing home 16%; or with home nursing 64%. RESULT Primary healing was achieved in 54%, minor amputation 8%, major amputation 9%, auto-amputation 2%, and 26% of the patients died unhealed. Among the oldest (88-96 years), 31% healed without any amputation. Extensive comorbidities were frequent: neuropathy 93%, visual impairment 73%, cardiovascular disease 60%, cerebrovascular disease 34%, and severe peripheral disease in 29% of the patients. Out of patients (80%) living in institutions or dependent on home nursing, 56% healed without amputation, compared to 44% of patients living in their own home without any support from social services or home nursing. CONCLUSION Healing without major amputation was achieved in 84% of surviving patients ≥75 years, despite extensive comorbidity and dependency.

Abstract
This study aims to evaluate clinical and ulcer characteristics as well the outcomes of patients with diabetic foot ulcers (DFUs). The study group was composed of DFUs patients managed by a limb salvage protocol according to guidance. Clinical and ulcers findings were described, and 1-year outcomes defined as limb salvage, healing, healing time, major amputation and death were compared between neuropathic and ischemic DFUs. One thousand, one hundred and ninety-eight subjects were included; 386 (32.2%) neuropathic and 812 (67.8%) ischemic DFUs. Neuropathic patients were younger (69.5 ± 11.5 vs. 74.5 ± 11.5, p < 0.0001) and reported less cases of nephropathy (22.8 vs. 39.6%, p < 0.0001), ischemic heart disease (22.8 vs. 36.9, p = 0.0004), cerebrovascular disease (8.3 vs. 17.2%, p = 0.002), heart failure (10.1 vs. 24.7%, p = 0.0002) and end-stage-renal-disease (ESRD) (5.4 vs. 27%, p = 0.0001) than ischemic patients; they also showed less cases of large (>5 cm2) (10.3 vs. 22.9%, p = 0.0007), infected (40.4 vs. 55.7%, p = 0.0005) and deep to the bone (22.3 vs. 39.2, p = 0.0002) ulcers, as well less multiple ulcerations (21.8 vs. 32.8%, p = 0.006) than patients with ischemic DFUs. The outcomes for neuropathic and ischemic DFUs were limb salvage (98.4 vs. 82.3%, p < 0.0001), healing (97.3 vs. 79.6%, p < 0.0001), healing time (34.9 vs. 35.6 weeks, p = 0.8), major amputation (0.5 vs. 6.6%, p = 0.0001), death (1.1 vs. 11%, p < 0.0001) respectively. Revascularization failure and ESRD were independent predictors of major amputation, while heart failure and number of co-morbidities (³5) were independent predictors of death. Ischemic DFUs patients showed more severe clinical and ulcers features as well worse outcomes than neuropathic DFUs patients.

Abstract
The purpose of this cross-sectional study is evaluate the effectiveness of a dermal-epidermal substitute (DES) composed of 3-dimensional porous matrix of type 1, purified, stabilized, bovin-origin collagen (Nevelia, SYMATESE, Chaponost, France) without a subsequent skin graft in the treatment ischemic postsurgical diabetic foot ulcers. This study group was composed of a sample of consecutive diabetic patients with critical limb ischemia and postsurgical wounds. All patients received a preset limb salvage protocol including the application of the DES, but none received a skin graft. Patients were closely followed until wound healing or different outcome. The outcome measures were healing, nonhealing, major amputation, and death evaluated at 1 and 2 years of follow-up. Forty-one patients were included. The average postsurgical wound area was 69.6 ± 50 cm2. Twenty-one patients (51%) healed; 10 patients (24%) did not heal after 1 year of follow-up; however, all of them achieved a mean ulcer size reduction >50%; 7 patients (17%) were amputees; 3 patients (7.3%) died. In a later follow-up (2 years), wounds in 8 additional patients healed. Successful revascularization was an independent predictor of healing (hazard ratio = 5.1, 95% confidence interval [CI] = 2.5-14-9; P = .0001), the postsurgical ulcer size (>50 cm2) was an independent predictor of nonhealing (hazard ratio = 6.2, 95% CI = 2.1-38.4; P = .0001) while recurrence of critical limb ischemia was an independent predictor of major amputation (odds ratio = 3.4, 95% CI = 1.1-4.5; P = .002). The DES composed of type 1 bovin-origin collagen is useful in the treatment of large postsurgical diabetic foot ulcers, even when the skin graft is not a suitable therapeutic option.
