Atherogenic markers and 1-year amputation risk in adults with diabetic foot in a tertiary level hospital: A retrospective cohort study. J Diabetes Complications 2024; 38:108810. [PMID: 39042958 DOI: 10.1016/j.jdiacomp.2024.108810] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 03/16/2024] [Revised: 07/07/2024] [Accepted: 07/11/2024] [Indexed: 07/25/2024]
Abstract
AIM To determine the association between atherogenic markers, such as total cholesterol/high density lipoprotein cholesterol ratio (TC/HDL-C), triglycerides/HDL-C ratio (TG/HDL-C), and triglycerides-glucose index (TyG), and the risk of 1-year amputation in adults with diabetic foot in a tertiary level hospital. METHODS Retrospective cohort study conducted in 162 adult patients with diabetic foot. The outcome was amputation, defined as "primary amputation in patients' clinical history after their first hospitalization due to foot ulcer.". The cutoff point was determined using Youden's J statistic. The relative risk (RR) was presented as an association measure. RESULTS A TyG index of >9.4 [RR: 1.64 (1.10-2.45)] was associated with a high risk of amputation after 1-year in adults with diabetic foot. However, while a TC/HDL ratio of >4.69 [RR: 1.38 (0.94-2.03)] and a TG/HDL-C ratio > 3.57 [RR: 1.35 (0.89-2.06)] did not show associations with risk of amputation after 1-year. CONCLUSIONS Only a TyG index of >9.4 was associated with an increased risk of 1-year amputation in adults with diabetic foot. Future studies with larger samples and a longitudinal design may provide more robust evidence and a better understanding of clinical implications.

Hart O, Bernau O, Khashram M. The Incidence and Outcomes of Major Limb Amputation in New Zealand from 2010 to 2021. J Clin Med 2024; 13:3872. [PMID: 38999438 PMCID: PMC11242113 DOI: 10.3390/jcm13133872] [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: 05/21/2024] [Revised: 06/22/2024] [Accepted: 06/24/2024] [Indexed: 07/14/2024] Open
Abstract
Background: Major limb amputation (MLA) can be a common outcome due to severe peripheral artery disease (PAD) and diabetic foot disease (DFD), and it carries a significant mortality burden. In New Zealand (NZ), there is little documentation of the incidence rate and mortality after MLA. The aim was to report the national crude and standardised rates and the mortality post MLA. Methods: This retrospective observational study included all MLAs that occurred within NZ from 1/1/2010 to 31/12/2021 due to DFD and/or PAD. Two national databases (National Minimum Dataset and the Australasian Vascular Audit) were utilised. The crude rates were calculated as cases per 100,000 in the NZ population per year including all ages (using the 2013 and 2018 NZ census figures). The age-standardised rates used the World Health Organization standard population. Post-operative mortality was calculated from the date of first hospitalisation for MLA. Results: From 2010 to 2021, there were 5293 MLA procedures in 4242 patients. On average, there were 8.5 MLAs per week and 441.1 MLAs annually. The overall crude rate was 9.44 per 100,000, and the standardised rate was 6.12 per 100,000. Over the 12 years, the crude rate decreased by 22% (p < 0.001), and the standardised rate decreased by 20.4% (p < 0.001). After MLA, the 30-day and 1-year mortality was 9.5% and 29.6%, respectively. From 2010 to 2021, the relative reduction in 30-day mortality was 45.1% (p < 0.001), and the reduction in 1-year mortality was 24.5% (p < 0.001). Increasing age, female sex and end-stage renal failure were predictors of 30-day and 1-year mortality. Conclusions: A considerable number of MLAs occur in NZ, with substantial perioperative mortality; however, the national incidence rates and mortality have improved over the last 12 years. This data might serve as benchmark to further reduce MLAs and improve patient outcomes.

Abstract
INTRODUCTION Reported prevalence for reamputation in diabetic foot is diverse, risk factors are not clear for minor amputations. This study aims to determine the prevalence for reamputation in diabetic foot from minor amputations and to evaluate associated factors for such outcome. METHODS Cross sectional study developed in 2hospitals. Patients hospitalized for diabetic foot ulcer requiring a minor amputation were included. A descriptive analysis of all variables is presented, as well as prevalence ratios (PR) and a multivariate logistic regression. RESULTS The prevalence was of 48% for 15 years. Toes were the most frequent minor amputation that required reamputation and above the knee amputation was the most frequent reamputation level (45%). Variables whose PR was associated to reamputation risk were: smoking history (PR 1.32, CI 95%: 1.02-1.67, P=0.03), vascular occlusion in doppler (PR 1.47, CI 95%: 1.11-1.73, P=0.01), revascularization (PR 1.73, CI 95%: 1.31-2.14, P=0.00002), Wagner> 3 (PR 1.75, CI 95%: 1.16-1.84, P=0.01) and leucocytosis> 11,000 (PR 1.39, CI 95%: 1.07-1.68, P=0.01). Leucocytosis> 11,000, Wagner> 3, vascular occlusion in doppler and revascularization were the variables that best predicted the outcome. Furthermore, leucocytosis was the best variable for predicting reamputation (OR 2.4, CI 95%: 1.1-5.6, P=0.04). CONCLUSIONS Reamputation prevalence was 48%. The toes were the minor amputation more frequently requiring reamputation and above the knee was the most frequent reamputation level. Risk for reamputation was associated with variables related to vascular compromise and infection.

Abstract
OBJECTIVE Early recognition of the need for surgical intervention is crucial in terms of limiting amputation level and decreasing mortality. We aimed to determine the risk factors for limb loss in patients with diabetic foot infection (DFI). METHOD Data of hospitalised patients with a DFI between 2010 and 2019 were collected retrospectively from their hospital records. Clinical and laboratory findings were analysed according to the type of treatment. RESULTS Data were collected for 401 patients, 280 (69.8%) of whom were male. The mean age was 59.6±11.1 years. Treatment modalities included: medical treatment (36.4%); debridement/drainage (21.9%); minor amputation (17.7%); and major amputation (23.9%). Forefoot infection (odds ratio (OR): 3.347; 95% confidence interval (Cl): 1.408-7.956) and peripheral arterial disease (OR: 4.990; 95% Cl: 1.225-20.324) were found to be significant in predicting limb loss, while duration of diabetes (≥20 years) and absence of forefoot infection were significant predictors of debridement/drainage. Subgroup analysis showed that high leukocyte levels (>16.4K/μl) and forefoot infections were independent predictors for major and minor amputation, respectively. CONCLUSION The clinical parameters used in this study are simple, broadly available, cost-effective and promising for predicting limb loss in patients with DFI.

Abstract
BACKGROUND Diabetic foot (DMF) complications are common and are increasing in incidence. Risk factors related to wound complications are yet to be established after trans-tibial amputation under the diagnosis of DMF infection. AIM To analyze the prognosis and risk factors related to wound complications after transtibial amputation in patients with diabetes. METHODS This retrospective cohort study included seventy-two patients with DMF complications who underwent transtibial amputation between April 2014 and March 2023. The groups were categorized based on the occurrence of wound complications, and we compared demographic data between the complication group and the non-complication group to analyze risk factors. Moreover, a multivariate logistic regression analysis was performed to identify risk factors. RESULTS The average follow-up period was 36.2 months. Among the 72 cases, 31 (43.1%) had wound complications. Of these, 12 cases (16.7%) received further treatment, such as debridement, soft tissue stump revision, and re-amputation at the proximal level. In a group that required further management due to wound complications after transtibial amputation, the hemoglobin A1c (HbA1c) level was 9.32, while the other group that did not require any treatment had a 7.54 HbA1c level. The prevalence of a history of kidney transplantation with wound complications after transtibial amputation surgery in DMF patients was significantly greater than in cases without wound complications (P = 0.02). Other factors did not show significant differences. CONCLUSION Approximately 43.1% of the patients with transtibial amputation surgery experienced wound complications, and 16.7% required additional surgical treatment. High HbA1c levels and kidney transplant history are risk factors for postoperative wound complications.

Abstract
BACKGROUND The decision to perform amputation of a limb in a patient with diabetic foot ulcer (DFU) is not an easy task. Prediction models aim to help the surgeon in decision making scenarios. Currently there are no prediction model to determine lower limb amputation during the first 30 days of hospitalization for patients with DFU. METHODS Classification And Regression Tree analysis was applied on data from a retrospective cohort of patients hospitalized for the management of diabetic foot ulcer, using an existing database from two Orthopaedics and Traumatology departments. The secondary analysis identified independent variables that can predict lower limb amputation (mayor or minor) during the first 30 days of hospitalization. RESULTS Of the 573 patients in the database, 290 feet underwent a lower limb amputation during the first 30 days of hospitalization. Six different models were developed using a loss matrix to evaluate the error of not detecting false negatives. The selected tree produced 13 terminal nodes and after the pruning process, only one division remained in the optimal tree (Sensitivity: 69%, Specificity: 75%, Area Under the Curve: 0.76, Complexity Parameter: 0.01, Error: 0.85). Among the studied variables, the Wagner classification with a cut-off grade of 3 exceeded others in its predicting capacity. CONCLUSIONS Wagner classification was the variable with the best capacity for predicting amputation within 30 days. Infectious state and vascular occlusion described indirectly by this classification reflects the importance of taking quick decisions in those patients with a higher compromise of these two conditions. Finally, an external validation of the model is still required. LEVEL OF EVIDENCE III.

Abstract
BACKGROUND Reamputation as a complication of diabetic foot ulcers presents a high economic burden and represents a therapeutic failure. It is paramount to identify as early as possible patients in whom a minor amputation may not be the best option. The purpose of this investigation was to do a case-controlled study to determine risk factors associated with re-amputation in patients with DFU (diabetic foot ulcers) at two University Hospitals. METHODS Multicentric, observational, retrospective, case-control study from clinical records of 2 university hospitals. Our study included 420 patients, with 171 cases (re-amputations), and 249 controls. We performed a multivariate logistic regression analysis and time-to-event survival analysis to identify re-amputation risk factors. RESULTS Statistically significant risk factors were artery history of tobacco use (p = 0.001); male sex (p = 0.048); arterial occlusion in Doppler ultrasound (p = 0.001); percentage of stenosis in arterial ultrasound >50 % (p = 0.053); requirement of vascular intervention (p = 0.01); and microvascular involvement in photoplethysmography (p = 0.033). The most parsimonious regression model suggests that history of tobacco use, male sex, arterial occlusion in ultrasound, and percentage of stenosis in arterial ultrasound >50 % remained statistically significant. The survival analysis identified earlier amputations in patients with larger occlusion in arterial ultrasound, high leukocyte count, and elevated ESR. CONCLUSION Direct and surrogate outcomes in patients with diabetic foot ulcers identify vascular involvement as an important risk factor for reamputation. LEVEL OF EVIDENCE III.

Abstract
In recent years, local antibiotic-loaded bone substitutes (ALBS) have been used increasingly in the treatment of diabetic foot infection (DFI). The meta-analysis aimed to analyse the efficacy of ALBS on patients with moderate to severe DFI (with or without osteomyelitis). With an appropriate search strategy, 7 studies were selected for analysis (2 RCTs and 5 cohort studies). The result showed that the application of ALBS effectively reduced the length of hospital stay (WMD -5.55; 95% CI: -9.85 to -1.26; P = 0.01), the recurrence rates (RR 0.33; 95% CI: 0.15 to 0.69; P = 0.003) and the mortality rates (RR 0.22; 95% CI: 0.06 to 0.82; P = 0.02). Compared to the control groups, however, there was no difference in healing rates (RR 1.06; 95% CI: 0.96 to 1.18; P = 0.26), healing time (WMD -1.44; 95% CI: -3.37 to -0.49; P = 0.14), the number of debridement (WMD -1.98; 95% CI: -4.08 to 0.12; P = 0.06) and major amputation rates (RR 0.76; 95% CI: 0.35 to 1.61; P = 0.47). The ALBS appears to have some beneficial effects as an adjunct to standard surgery in the treatment of DFI with or without osteomyelitis, as it reduces recurrence rates, mortality rates, and length of hospital stay, but there was no statistically significant difference in enhancing wound healing.

Abstract
Objective. Besides the early detection and treatment of diabetic foot ulcers, being aware of the risk factors for major amputation plays a crucial role in preventing the major lower limb amputations. Major lower limb amputations are not just mentally and physically hard for patients, but also have an effect on patient's survival and are a financial burden on both patients and healthcare systems. Subjects and Methods. We defined 37 potential risk factors for major amputation and these risk factors were investigated among 507 patients who had ulcers in their feet and were seen by the diabetic foot ulcer council at Ege University Faculty of Medicine. In our study, 106 (20.9%) patients ended up undergoing major lower limb amputation. Results. The univariate analysis showed that 24 defined risk factors were statistically significant. In the multivariate analysis using the Cox regression model, 6 risk factors remained statistically significant. Multivariate-adjusted hazard ratios were 4.172 for hyperlipidemia, 3.747 for albumin <3.365 g/dL, 3.368 for C-reactive protein (CRP) >2.185 mg/L, 2.067 for presence of gangrenous Wagner stage, 1.931 for smoking tobacco >30 pack/year, and 1.790 for hematocrit (HCT) <31.5%. Most patients with major amputation presented with a neuroischemic foot (58%). Gender and age were not found to be risk factors for major amputation. Having less than 7% of hemoglobin A1c (HbA1c) levels had a direct proportion with major amputation numbers. The mortality rates in one year, two and three years after the major amputation operations were 24.6%, 30%, and 35.9%, respectively. Conclusion. Being familiar with these risk factors for major amputation is crucial for multi-disciplinary teams to take good care of patients with diabetic foot ulcers and to lower the need for major amputations.

Abstract
OBJECTIVES To analyze clinical characteristics of the diabetic inpatients with foot ulcers and explore the risk factors of lower extremity amputation (LEA) in West China Hospital of Sichuan University. METHODS A retrospective analysis was performed based on the clinical data of the patients with diabetic foot ulcer (DFU) hospitalized in West China Hospital of Sichuan University from January 1, 2012 to December 31, 2020. The DFU patients were divided into three groups: non-amputation, minor amputation, and major amputation groups. The ordinal logistic regression analysis was used to identify the risk factors for LEA. RESULTS 992 diabetic patients (622 males and 370 females) with DFU were hospitalized in the Diabetic Foot Care Center of Sichuan University. Among them, 72 (7.3%) (55 minor amputations and 17 major amputations) cases experienced amputation, and 21(2.1%) refused amputation. Excluding the patients who refused amputation, the mean age and duration of diabetes of and HbA1c the 971 patients with DFU, were 65.1 ± 12.3 years old, 11.1 ± 7.6 years, and 8.6 ± 2.3% respectively. The patients in the major amputation group were older and had longer course of diabetes for a longer period of time than those in the non-amputation and minor amputation groups. Compared with the non-amputation patients (55.1%), more patients with amputation (minor amputation (63.5%) and major amputation (88.2%)) suffered from peripheral arterial disease (P=0.019). The amputated patients had statistically lower hemoglobin, serum albumin and ankle brachial index (ABI), but higher white blood cell, platelet counts, fibrinogen and C-reactive protein levels. The patients with amputation had a higher incidence of osteomyelitis (P = 0.006), foot gangrene (P < 0.001), and a history of prior amputations (P < 0.001) than those without amputation. Furthermore, a history of prior amputation (odds ratio 10.194; 95% CI, 2.646-39.279; P=0.001), foot gangrene (odds ratio 6.466; 95% CI, 1.576-26.539; P=0.010) and ABI (odds ratio 0.791; 95% CI, 0.639-0.980; P = 0.032) were significantly associated with LEAs. CONCLUSIONS The DFU inpatients with amputation were older with long duration of diabetes, poorly glycemic control, malnutrition, PAD, severe foot ulcers with infection. A history of prior amputation, foot gangrene and a low ABI level were the independent predictors of LEA. Multidisciplinary intervention for DFU is essential to avoid amputation of the diabetic patients with foot ulcer.

Abstract
BACKGROUND Diabetic foot osteomyelitis (DFO) often leads to amputations in the lower extremity. Data on the influence of the initial anatomical DFO localization on ultimate major amputation are limited. METHODS In this retrospective analysis, 583 amputation episodes in 344 patients (78 females, 266 males) were analyzed. All received a form of amputation in combination with antibiotic therapy. A multivariate logistic regression analysis with the primary outcome "major amputation" defined as an amputation above the ankle joint was performed. The association of risk factors including location of DFO, coronary artery disease, peripheral artery disease, neuropathy, nephropathy, and Charcot neuro-osteoarthropathy was analyzed. RESULTS Among 583 episodes, DFO was located in the forefoot in 512 (87.8%), in the midfoot in 43 (7.4%), and in the hindfoot in 28 episodes (4.8%). Overall, 53 of 63 (84.1%) major amputations were performed because of DFO in the setting of peripheral artery disease as primary indication. Overall, limb loss occurred in 6.1% (31/512) of forefoot, 20.9% (9/43) of midfoot, and 46.4% (13/28) of hindfoot DFO. Among these, 22 (41.5%) were performed as the primary treatment, whereas 31 (58.5%) followed previously failed minor amputations. Among this latter group of secondary major amputations, the DFO was localized to the forefoot in 23 of 583 (3.9%), the midfoot in 4 of 583 (0.7%) and the hindfoot in 4 of 583 (0.7%). In multivariate logistic regression analysis, initial hindfoot localization was a significant factor (P < .05), whereas peripheral artery disease, smoking, and a midfoot DFO were not found to be risk factors. CONCLUSION In our retrospective series, the frequency of limb loss in DFO increased with more proximal initial foot DFO lesions, with almost half of patients losing their limbs with a hindfoot DFO. LEVEL OF EVIDENCE Level IV, retrospective cohort study.

Abstract
Background Infected diabetic foot ulcers (IDFU) are a major complication of diabetes mellitus. These potentially limb-threatening ulcers are challenging to treat due to impaired wound healing characterizing diabetic patients and the complex microbial environment of these ulcers. Aim To analyze the microbiome of IDFU in association with clinical outcomes. Methods Wound biopsies from IDFU were obtained from hospitalized patients and were analyzed using traditional microbiology cultures, 16S rRNA sequencing and metagenomic sequencing. Patients’ characteristics, culture-based results and sequencing data were analyzed in association with clinical outcomes. Results A total of 31 patients were enrolled. Gram-negative bacteria dominated the IDFU samples (79%, 59% and 54% of metagenomics, 16S rRNA and cultures results, respectively, p<0.001). 16S rRNA and metagenomic sequencing detected significantly more anaerobic bacteria, as compared to conventional cultures (59% and 76%, respectively vs. 26% in cultures, p=0.001). Culture-based results showed that Staphylococcus aureus was more prevalent among patients who were treated conservatively (p=0.048). In metagenomic analysis, the Bacteroides genus was more prevalent among patients who underwent amputation (p<0.001). Analysis of metagenomic-based functional data showed that antibiotic resistance genes and genes related to biofilm production and to bacterial virulent factors were more prevalent in IDFU that resulted in amputation (p<0.001). Conclusion Sequencing tools uncover the complex biodiversity of IDFU and emphasize the high prevalence of anaerobes and Gram-negative bacteria in these ulcers. Furthermore, sequencing results highlight possible associations among certain genera, species, and bacterial functional genes to clinical outcomes.

Abstract
A majority of lower extremities neuro‐ischaemic wounds (NIU) are related to: (a) only diabetes (DM); (b) only peripheral artery disease (PAD); (c) co‐existing diabetes and peripheral artery disease (DM‐PAD). This study aims to characterise the major clinical outcomes of forementioned three groups of lower extremity wound patients in Singapore. Patients hospitalised for lower extremity NIU between January 2014 and October 2017 in a tertiary hospital in Singapore were analysed. Patients' major limb amputation and mortality were assessed using Cox regression models. Cumulative survival and amputation‐free survival among the three classified groups were calculated using Kaplan‐Meier analysis. Compared with patients with only DM, those in the PAD group and the DM‐PAD group had higher risk of major limb amputation (adjusted hazard ratio: 2.47, 95% CI: 1.65‐3.70; adjusted hazard ratio: 2.01, 95% CI: 1.53‐2.65 respectively) and mortality (adjusted hazard ratio: 2.36, 95% CI: 1.57‐3.55; adjusted hazard ratio: 2.46, 95% CI: 1.86‐3.26 respectively). The 3‐year survival and amputation‐free survival were lowest in the DM‐PAD group (52.1% and 41.5% respectively), followed by the PAD group (53.3% and 44.6% respectively) and the DM group (74.2% and 68.5% respectively). Lower extremity NIU patients with PAD or DM‐PAD were found to have poorer clinical prognosis than those with DM only.

Abstract
Wounds and tissue defects of the hand and foot often lead to severe functional impairment of the affected extremity. Next to general principles of wound healing, special functional and anatomic considerations must be taken into account in the treatment of wounds in these anatomical regions to achieve a satisfactory reconstructive result. In this article, we outline the concept of wound healing and focus on the special aspects to be considered in wounds of the hand and foot. An overview of different treatment and dressing techniques is given with special emphasis on the reconstruction of damaged structures by plastic surgical means.

Abstract
Background Diabetic foot ulcer (DFU) is one of the most serious complications of diabetes mellitus with devastating outcomes. Poorly treated DFU leads to osteomyelitis, gangrene and limb amputation. There is an increased risk of mortality for the amputees and increased number of bacterial resistance in survived patients. Struggle on choice of the best antibiotic(s) for DFU is escalating. Objectives To determine risk factors associated with mortality in patients with DFU. To investigate bacterial drug resistance in survived or deceased patients around amputation. Methodology This is a retrospective cohort study that involved all diabetic patients who had DFU or minor or major amputation at Hebron Governmental Hospital from 2013 to 2020. Antibiotic use and bacterial isolates along with culture and sensitivity test results were retrieved from patients' profiles and laboratory records. Major outcome of study was survival rate around amputation. Patients who missed test results for FBS or HbAc1, or who had no wound culture were excluded. SPSS version 22 was used to analyze data. Results Eighty four subjects were included in this study, 64.8 ± 12.58 years old, 63.1% males who had diabetic foot ulcer, minor or major limb amputation between 2013 and 2020 at Hebron Governmental Hospital. Forty tow patients (50%) had diabetic foot ulcer, 28 patients (33.3%) had major limb amputation, and 14 patients (16.7%), succumbed to minor amputation. Average FBS was 292.8 ± 136.33 mg/dl and average HbA1C was 8.55 ± 1.89%. Mortality rate was 9.5%. Using the Chi square test, we found a significant relationship between mortality and type of isolated bacteria, p = 0.033 and between diabetic complications (nephropathy) and mortality, p = 0.033. There was a significant relationship between antibiotic use and mortality, p = 0.04, especially with metronidazole and colistin, if they were used around limb amputation. Conclusions Mortality of diabetic patients with DFU was associated with nephropathy and Acinetobacter or E. coli infections.

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

Abstract
The risk of amputation is a sequelae of diabetic foot ulceration, which are significantly increased in diabetic patients and caused huge morbidly and mortality. However, whether the risk amputation in diabetic patients are differing in male and female remains inconclusive. We therefore conducted a systematic review and meta-analysis to assess the sex difference for the risk of amputation in diabetic patients. We systematically searched PubMed, EmBase, and the Cochrane library to identify eligible study from their inception up to November 2020. The diagnostic value of male patients on subsequent amputation risk were assessed by using sensitivity, specificity, positive and negative likelihood ratio (PLR and NLR), diagnostic odds ratio (DOR), and area under the receiver operating characteristic curve (AUC). Twenty-two studies recruited a total of 33,686,171 diabetic patients were selected for quantitative analysis. The risk of amputation in male diabetic patients was greater than female diabetic patients (DOR: 1.38; 95%CI: 1.13–1.70; P<0.001). The sensitivity and specificity for male diabetic patients on the risk of amputation were 0.72 (95%CI: 0.72–0.73), and 0.51 (95%CI: 0.51–0.51), respectively. Moreover, the PLR and NLR of male diabetic patients for predicting amputation were 1.13 (95%CI: 1.05–1.22), and 0.82 (0.72–0.94), respectively. Furthermore, the AUC for male diabetic patients on amputation risk was 0.56 (95%CI: 0.48–0.63). This study found male diabetic patients was associated with an increased risk of amputation than female diabetic patients, and the predictive value of sex difference on amputation risk in diabetic patients was mild.

Abstract
Diabetic foot ulcers (DFUs) are a common but highly morbid complication of long-standing diabetes, carrying high rates of associated major amputation and mortality. As the global incidence of diabetes has increased, along with the lifespan of the diabetic patient, the worldwide burden of DFUs has grown steadily. Outcomes in diabetes and DFUs are known to depend strongly on social determinants of health, with worse outcomes noted in minority and socioeconomically disadvantaged populations. Effective treatment of DFUs is complex, requiring considerable expenditure of resources and significant cost to the health care system. Comprehensive care models with multidisciplinary teams have proven effective in the treatment of DFUs by decreasing barriers to care and increasing access to the multiple specialists required to provide timely and effective DFU procedural intervention, surveillance, and preventative care. Vascular surgeons are an integral part throughout the cycle of care for DFUs and should be involved early in the course of such patients to maximize their contributions to a multidisciplinary care model.

Abstract
AIMS Infection in diabetic foot syndrome (DFS) represents serious medical problem, and the annual risk of DFS in diabetic patients is 2.5%. More than half of the patients with DFS have symptoms of extremity ischemia (peripheral arterial disease (PAD)). The aim of the present study was to analyze the frequency of particular bacterial strains in people with DFS, analyze the impact of arterial ischemia on the occurrence of a given pathogen, and evaluate the antibacterial treatment based on the results of bacterial culture. METHODS The analysis included 844 bacterial strains obtained from 291 patients with DFS hospitalized in the Department of Angiology in years 2016-2019. RESULTS The most common isolates were Staphylococcus aureus, Enterococcus faecalis, Enterobacter cloacae, Pseudomonas aeruginosa, and Acinetobacter baumannii. Nearly 20% of the species were found to have at least one resistance mechanism. In patients with PAD, Gram-negative species were isolated more commonly than in people without PAD. The most useful drugs in DFS in hospitalized patients are penicillins with beta-lactamase inhibitors, 3rd- to 5th-generation cephalosporins (with many exceptions), carbapenems, aminoglycosides, and tigecycline. CONCLUSIONS Bacterial strains isolated from ischemic DFS are more resistant to commonly used antibacterial agents, i.e., penicillins (including penicillins with beta-lactamase inhibitors), cephalosporins (except for the 4th and 5th generations), glycopeptides, and linezolid. When planning treatment of hospitalized patients with DFS, the presence of ischemia in DFS should always be taken into consideration. It determines the occurrence of particular bacterial species and the choice of antibacterial agent and may determine the rate of treatment success.

Biobehavioral Intervention Targeting Physical Activity Behavior Change for Older Veterans after Nontraumatic Amputation: A Randomized Controlled Trial. PM R 2020; 12:957-966. [PMID: 32248638 PMCID: PMC8229675 DOI: 10.1002/pmrj.12374] [Citation(s) in RCA: 10] [Impact Index Per Article: 2.5] [Reference Citation Analysis] [Abstract] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/07/2020] [Revised: 03/24/2020] [Accepted: 03/25/2020] [Indexed: 01/03/2023]
Abstract
BACKGROUND Lower-limb amputation (LLA) due to non-traumatic vascular etiology is linked to extremely low physical activity and high disability. OBJECTIVE To test the feasibility of a biobehavioral intervention designed to promote physical activity. DESIGN A randomized, single-blind feasibility trial with a crossover design. SETTING Veterans Administration Medical Center. PARTICIPANTS Military veterans (age: 65.7 [7.8] years; mean [standard deviation]) with nontraumatic lower-limb amputation (LLA), randomized to two groups: GROUP1 (n = 16) and GROUP2 (n = 15). Both groups had similar baseline amputation characteristics (level of amputation and time since amputation). INTERVENTIONS Twelve weekly, 30-minute telehealth sessions of physical activity behavior-change intervention, with GROUP1 participating in weeks 1-12 and GROUP2 in weeks 13-24. GROUP1 noncontact phase in weeks 13-24 and GROUP2 attention control telehealth phase in weeks 1-12. MAIN OUTCOME MEASURES Feasibility (participant retention, dose goal attainment, intervention acceptability [Intrinsic Motivation Inventory [IMI] Interest and Enjoyment scale], safety) and signal of efficacy (free-living physical activity [accelerometer-based average daily step count], Late Life Function and Disability Index - Disability Scale [LLFDI-DS]). RESULTS Participant retention rate was high (90%), with three participants lost to follow-up during the intervention period. Dose goal attainment was low, with only 10% of participants achieving an a priori walking dose goal. Intervention was rated as acceptable, with mean IMI Interest and Enjoyment score (5.8) statistically higher than the null value of 5.0 (P = .002). There were no between-group differences in adverse event rates (falls: P = .19, lower extremity wounds: P = .60). There was no signal of efficacy for change in average daily step count (d = -0.15) or LLFDI-DS (d = -0.22 and 0.17 for frequency and limitations scales, respectively). CONCLUSIONS Telehealth delivered biobehavioral intervention resulted in acceptable participant retention, low dose goal attainment, high participant acceptability, and low safety risk, while having no signal of efficacy (physical activity, disability) for people with nontraumatic LLA.

Abstract
BACKGROUND The cost of care for diabetic foot ulcers has became a global economic burden. The study aimed to analyze diabetic foot ulcer cost changes over time and to identify factors associated with these variables, so as to strengthen and improve the management of diabetic foot ulcers. METHODS We retrospectively analyzed the data in the electronic medical record system of our wound treatment center. The homepage of the system was queried using the national clinical version 2.0 disease diagnosis code (ICD-10), the data of patient's basic information were exported. Through the statistics and analysis of these data, the socioeconomic changes and possible risk factors of diabetic foot ulcers management in recent years were obtained. RESULTS There were 3654 patients included in the study, an average of 522 per year. The total cost per patient increased from ¥15,535.58 in 2014 to ¥42,040.60 in 2020, with an average of ¥21,826.91. The average length of stay between 14.29 days and 31.4 days from 2014 to 2020, with an average of 18.10 days. Besides, the average incidence of peripheral arterial disease in diabetic foot ulcers patients admitted was as high as 81.9%, and the average amputation rate was 9.9%. The study reflected the total cost and length of stay of diabetic foot patients increased significantly from 2014 to 2020, which were related to age (>85 years), gender (male), peripheral arterial disease, amputation (P < 0.05). CONCLUSION A heavy cost from diabetic foot ulcers and its complications was significantly increased yearly, which was related to older age, co-morbidity, amputation and duration of hospitalization. The prevention and treatment of diabetic foot ulcers have a long way to go, early comprehensive prevention and multi-disciplinary cooperation may still be an effective way.

Abstract
Introduction: Diabetic foot infection, a complication which can lead to lower limb amputation, is a major source of morbidity and mortality in Malaysia. The objective of this study was to determine the predictive factors of major lower limb amputation among patients with diabetes mellitus in a cluster of three district hospitals in Pahang, Malaysia. Materials and Methods: This cross-sectional study involved 170 patients who had undergone surgical interventions for diabetic foot infections at three district hospitals from 1st of September 2014 to 31st December 2015. The predictors for major amputation of lower limb were determined using simple logistic regression (LR) and forward LR multiple logistic regression. Results: A total of 21 patients had undergone major amputations of lower limb (15 transtibial and 6 transfemoral). The following factors were associated with major amputation of lower limb; longer duration of disease, age ≥ 60 years, patients from Bentong Hospital, presence of hypertension, presence of fever, history of multiple limb-salvaging surgeries, monomicrobial culture, necrotising fasciitis, anemia and leukocytosis. Upon forward LR multiple logistic regression, only duration of disease, history of more than three previous limb-salvaging surgeries and total white blood cell count ≥15X109/L were found to be significant as predictive factors of major amputation of lower limb. Conclusion: Among the factors analysed in this study, a longer duration of disease, raised total white blood cell count and history of more than three limb-salvaging surgeries were identified as predictors for major amputation of lower limb in diabetic foot infections using stepwise logistic regression analysis.

Abstract
BACKGROUND Knowledge of risk factors is crucial to develop management and treatment protocols for the prevention of lower extremity amputation for patients with diabetic foot infections (DFIs). METHODS We searched the research literature for studies reporting risk factors for lower extremity amputation in patients with DFI. The main outcome variables included both minor and major amputations. This study was reported in accordance with the Preferred Reporting Items for Systematic Reviews and Meta-analyses (PRISMA) guidelines, and the protocol was registered in PROSPERO (CRD42018118543). RESULTS A total of 2471 potential articles from the database search met the inclusion criteria. After reviewing the titles, abstracts, and full texts, remaining 25 articles were included in the final analysis. We identified 6132 patients with DFI in the 25 included articles. Of these, 1873 patients who underwent amputation were investigated. Male gender (odds ratio [OR]: 1.31), smoking (OR: 1.38), history of amputation (OR: 1.47), history of osteomyelitis (OR: 1.94), peripheral arterial disease (OR: 2.35), retinopathy (OR: 1.32), International Working Group on the Diabetic Foot (IWGDF) grades 3 and 4 (OR: 1.7 and 2.5), Wagner grades 4 and 5 (OR: 4.3 and 6.4), gangrene/necrosis (OR: 9.9), osteomyelitis (OR: 4.5), neuroischaemic DFI (OR: 3.06), severe infection (OR: 3.12), length of hospitalization (standardized mean difference [SMD]: 0.7), leukocytosis (OR: 1.76), mean erythrocyte sedimentation rate (ESR) (SMD: 0.5), mean C-reactive protein (CRP) (SMD: 0.8), tissue culture positivity (OR: 1.61), and isolation of Gram-negative bacteria from tissue culture (OR: 1.5) were found as predictors of amputation in DFI. CONCLUSIONS The present study highlighted some differences in diabetic foot ulcers and DFIs in terms of risk factors for lower extremity amputation. These data provide detailed information about risk factors for amputations among patients with DFI, thus contributing to the creation of new classification systems for assessment of high-risk patients.

Abstract
BACKGROUND Lower extremity amputations (LEAs) in diabetic patients are common in the indigenous population. There is no published data from the Northern Territory. METHODS All patients with diabetic foot ulcer, presenting for the first time to the multi-disciplinary foot clinic at Royal Darwin Hospital, between January 2003 and June 2015, were included. These patients were followed until 2017, or death. LEA rates over the follow-up period and the risk factors were studied. RESULTS Of the 513 included patients, 62.8% were males and 48.2% were indigenous. The majority (93.6%) had type 2 diabetes with median diabetes duration of 7.0 years (interquartile range 3-12). During the follow-up period of 5.8 years (interquartile range 3.1-9.8), a total of 435 LEAs (16.6% major; 34.7% minor) occurred in 263 patients (mean age 57.0 ± 11.8 years). In multivariate analysis, the following variables were associated with LEAs (adjusted odds ratio (95% confidence interval)): prior LEA (4.49 (1.69-11.9)); peripheral vascular disease (2.67 (1.27-5.59)); forefoot ulcer (7.72 (2.61-22.7)); Wagner grade 2 (3.71 (1.87-7.36)); and Wagner grade 3 (17.02 (3.77-76.72)). Indigenous patients were 1.8 times more likely to have LEAs than non-indigenous patients. Indigenous amputees were approximately 9 years younger than their non-indigenous counterparts. CONCLUSION Half of patients presenting with diabetic foot ulcer had LEA during follow-up. Prior LEAs, peripheral vascular disease, forefoot ulcers and higher Wagner grades were independent risk factors for LEA. Indigenous patients were at higher risk for LEAs and were younger at the time of amputation.

Abstract
IMPACT STATEMENT Nonhealing skin wounds remain a significant burden on health care systems, with diabetic patients 20 times as likely to undergo a lower extremity amputation due to impaired healing. Novel treatments that suppress the proinflammatory signature and induce the proliferative and remodeling phases are needed clinically. We demonstrate that the addition of periostin and CCN2 in a scaffold form increases closure rates of full-thickness skin wounds in diabetic mice, concomitant with enhanced angiogenesis. Our results demonstrate the efficacy of periostin- and CCN2-containing biomaterials to stimulate wound closure, which could represent a novel method for the treatment of diabetic skin wounds.

Abstract
AIMS The diabetic foot syndrome (DFS) is a serious complication in patients with diabetes increasing the risk for minor/major amputations. This analysis aimed to examine differences in diabetes patients with or without DFS stratified by type 1 (T1D) or type 2 diabetes (T2D). MATERIAL AND METHODS Adult patients (≥20y of age) with diabetes from the German/Austrian diabetes patients follow-up registry (DPV) were included. The cross-sectional study comprised 45 722 subjects with T1D (nDFS = 2966) and 313 264 with T2D (nDFS = 30 904). In DFS, minor/major amputations were analysed. To compare HbA1C , neuropathy, nephropathy, cardiovascular disease risk factors, and macrovascular complications between patients with or without DFS, regression models were conducted. Confounders: age, sex, diabetes duration. RESULTS In patients with DFS, a minor amputation was documented in 27.2% (T1D) and 25.9% (T2D), a major amputation in 10.2% (T1D) and 11.3% (T2D). Regression models revealed that neuropathy was more frequent in subjects with DFS compared with patients without DFS (T1D: 70.7 vs 29.8%; T2D: 59.4% vs 36.9%; both P < 0.0001). Hypertension, nephropathy, peripheral vascular disease, stroke, or myocardial infarction was more common compared with patients without DFS (all P < 0.0001). In T1D with DFS, a slightly higher HbA1C (8.11% vs 7.95%; P < 0.0001) and in T2D with DFS a lower HbA1C (7.49% vs 7.69%; P < 0.0001) was observed. CONCLUSIONS One third of the patients with DFS had an amputation of the lower extremity. Especially neuropathy or peripheral vascular disease was more prevalent in patients with DFS. New concepts to prevent DFS-induced amputations and to reduce cardiovascular risk factors before the occurrence of DFS are necessary.

Abstract
PURPOSE OF REVIEW This review will summarize recent findings of the effect of supplemental fatty acids, with an emphasis on omega-3 polyunsaturated fatty acids, as a treatment for diabetic peripheral neuropathy. RECENT FINDINGS Pre-clinical studies have provided evidence that treating diabetic rodents with δ linolenic acid (omega-6 18:3) and to a greater extent with eicosapentaenoic and docosahexaenoic acids (omega-3 20:5 and 22:6, respectively) improve and even reverse vascular and neural deficits. Additional studies have shown resolvins, metabolites of eicosapentaenoic and docosahexaenoic acids, can induce neurite outgrowth in neuron cultures and that treating type 1 or type 2 diabetic mice with resolvin D1 or E1 provides benefit for peripheral neuropathy similar to fish oil. Omega-3 polyunsaturated fatty acids derived from fish oil and their derivatives have anti-inflammatory properties and could provide benefit for diabetic peripheral neuropathy. However, clinical trials are needed to determine whether this statement is true.

Abstract
Current biological treatments for non-healing wounds aim to address the common deviations in healing mechanisms, mainly inflammation, inadequate angiogenesis and reduced synthesis of extracellular matrix. In this context, regenerative medicine strategies, i.e., platelet rich plasmas and mesenchymal stromal cell products, may form part of adjuvant interventions in an integral patient management. We synthesized the clinical experience on ulcer management using these two categories of biological adjuvants. The results of ten controlled trials that are included in this systematic review favor the use of mesenchymal stromal cell based-adjuvants for impaired wound healing, but the number and quality of studies is moderate-low and are complicated by the diversity of biological products. Regarding platelet-derived products, 18 controlled studies investigated their efficacy in chronic wounds in the lower limb, but the heterogeneity of products and protocols hinders clinically meaningful quantitative synthesis. Most patients were diabetic, emphasizing an unmet medical need in this condition. Overall, there is not sufficient evidence to inform routine care, and further clinical research is necessary to realize the full potential of adjuvant regenerative medicine strategies in the management of chronic leg ulcers.
