Abstract
Despite many improvements have been achieved, diabetic foot disease (DFD) remains a clinical, social, and economic burden. In the last years, DFD showed an evolution of its characteristics with an increase of the ischaemic/neuro-ischaemic foot in comparison to the pure neuropathic foot. Simultaneously, there was and increased incidence of concomitant cardiovascular co-morbidities, which influences the higher fragility of patients with DFS. Peripheral arterial disease (PAD) in subjects with diabetic foot seems to show a more aggressive pattern, being more distal and difficult to treat. Untreatable PAD remains the unmet need for clinicians and the main risk factor of major amputation in patients with diabetic foot ulcers. Authors aimed to describe the evolution of diabetic foot patients in the last two decades, describing also the current and future treatment which may improve outcomes in the next generations.

A new declaration for feet's sake: Halving the global diabetic foot disease burden from 2% to 1% with next generation care. Diabetes Metab Res Rev 2024; 40:e3747. [PMID: 37997627 DOI: 10.1002/dmrr.3747] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 10/30/2023] [Accepted: 10/31/2023] [Indexed: 11/25/2023]
Abstract
The 1989 Saint Vincent Declaration established a goal of halving global diabetes-related amputation rates. A generation later, this goal has been achieved for major but not minor amputations. However, diabetic foot disease (DFD) is not only a leading cause of global amputation but also of hospitalisation, poor quality of life (QoL) and disability burdens. In this paper, we review latest estimates on the global disease burden of DFD and the next generation care of DFD that could reduce this burden. We found DFD causes 2% of the global disease burden. This makes DFD the 13th largest of 350+ leading conditions causing the global disease burden, and much larger than dementia, breast cancer and type 1 diabetes. Neuropathy without ulcers and amputations makes up the largest portion of the global DFD burden yet receives the least DFD focus. Future care focussed on improving safe physical activity in people with DFD could considerably reduce the DFD burden, as this incorporates increasing physical fitness and QoL, while simultaneously decreasing ulceration and other risks. Charcot neuro-osteoarthropathy is more prevalent than previously thought. Most cases respond well to non-removable offloading devices, but surgical intervention may further reduce the considerable burden of these neuropathic fracture dislocations. Ischaemia is becoming more common and complex. Most cases respond well to revascularisation interventions, but novel revascularisation techniques, medical management and autologous cell therapies may hold the key to more cases responding in the future. We conclude that DFD causes a global disease burden larger than most conditions and existing guideline-based care and next generation treatments can reduce this burden. We suggest the World Health Organization and International Diabetes Federation declare a new goal: halving the global DFD burden from 2% to 1% within the next generation.

Impact of multidisciplinary care of diabetic foot infections for inpatients at Campbelltown Hospital. BMC Health Serv Res 2023; 23:1126. [PMID: 37858102 PMCID: PMC10588009 DOI: 10.1186/s12913-023-10119-0] [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: 04/11/2023] [Accepted: 10/05/2023] [Indexed: 10/21/2023] Open
Abstract
BACKGROUND Diabetic foot infection (DFI), including diabetic foot ulcer, is a serious complication of diabetes, particularly in the South Western Sydney (SWS) region where it is a leading cause of diabetes-related hospitalisations. Multidisciplinary team (MDT) involvement is effective at improving the health outcomes of DFI patients. This study investigated the impact of MDT (High Risk Foot Service, HRFS) on the length of stay and surgical outcomes of inpatients with DFI in a Sydney tertiary hospital. METHOD A retrospective audit of electronic medical records of inpatient admissions for DFI at Campbelltown Hospital between January 2019 - December 2021, was performed. The main outcome of the study was MDT involvement, defined as having two or more specialities involved in the patient's treatment. The other measured variables included length of stay (defined as the total duration from admission to discharge), and surgical outcomes including debridement, minor amputation, and major amputation. RESULTS Over the three years, 78 participants presented to the hospital for 89 unique DFI admissions. There were 24 admissions in 2019, 28 admissions in 2020, and 37 admissions in 2021, with MDT attendance showing a steady increase at 62.5%, 75.0% and 83.8% respectively. Patients with serious comorbidities such as chronic kidney disease were more likely to have MDT involvement (84.8% vs. 15.2%, P = 0.048). Imaging was more likely to be performed with MDT involvement (78.8% vs. 21.3%, p < 0.05). Comparing patients who received and did not receive MDT care, the mean HbA1c (%) (8.4 ± 2.0 vs. 8.2 ± 2.7, P = 0.701), median length of stay (LOS: 7.8, IQR 15.0 days vs. 4.8 IQR 7.9 days, P = 0.243) and rate of surgical outcomes (74.6% vs. 72.7%, P = 0.262) were similar. Patients who required major amputation had significantly longer LOS (24 days, IQR 21.5 vs. 5.2 days, IQR 13.0, P = 0.004) but similar HbA1c (P = 0.552) compared to those who had conservative intervention. CONCLUSION Adopting an MDT approach was associated with more thorough investigation of DFI, with similar rates of surgical outcomes. Further research on the impacts of MDT on length of stay and surgical outcomes of DFI patients in other SWS hospitals is needed.

Hospital Readmission in Patients With Diabetic Foot Ulcers: Prevalence, Causes, and Outcomes. INT J LOW EXTR WOUND 2023:15347346231207747. [PMID: 37849322 DOI: 10.1177/15347346231207747] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Indexed: 10/19/2023]
Abstract
The aim of the current study was to evaluate the rate of readmission in patients affected by diabetes and foot ulcers (DFUs), and causes and outcomes of patients requiring a new hospitalization. The current study is a retrospective observational study including patients who have required hospitalization since January 2019 to September 2022 due to a DFU. Once patients were discharged, they were regularly followed as outpatients. Within 6 months of follow-up, the rate of hospital readmission for a diabetic foot problem was recorded. According to the readmission or not, patients were divided into 2 groups, readmitted and not readmitted patients, respectively. Hence, all patients were followed for 6 months more and outcomes of the 2 groups were analyzed and compared. Overall, 310 patients were included. The mean age was 68 ± 12 years, the majority of patients reported type 2 diabetes (>90%), and the mean diabetes duration was approximately 20 years. Sixty-eight (21.9%) patients were readmitted. The main reason for hospital readmission was the presence of critical limb ischemia (CLI) in the contralateral limb (6.1%), the recurrence of CLI in the previous treated limb (4.5%), and the onset of new infected DFU in the contralateral foot (4.5%). Readmitted patients reported lower rate of healing (51.5% vs 89.2%, P < .0001) and higher rate of major amputation (10.3% vs 4.5%, P = .2) in comparison to not readmitted patients. Critical limb ischemia resulted in the only independent predictor of hospital readmission. Hospital readmission is a frequent issue among patients with DFUs, and readmitted patients showed a lower chance of wound healing. Critical limb ischemia resulted in the main cause of new hospitalization.

Association between triglyceride glucose index and severity of diabetic foot ulcers in type 2 diabetes mellitus. J Foot Ankle Res 2023; 16:68. [PMID: 37794445 PMCID: PMC10552301 DOI: 10.1186/s13047-023-00663-7] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 04/14/2023] [Accepted: 09/04/2023] [Indexed: 10/06/2023] Open
Abstract
BACKGROUND Triglyceride glucose (TyG) index is a good surrogate biomarker to evaluate insulin resistance (IR). The study aimed to investigate whether the TyG index is related to the severity of diabetic foot ulcers (DFUs) in patients with type 2 diabetes mellitus (T2DM). METHODS A total of 1059 T2DM patients were enrolled in this observational, retrospective, single-center study. TyG index was calculated as ln[fasting triglycerides (mg/dl) × fasting glucose (mg/ dl)/2]. The severity of DFUs was classified into mild-to-moderate DFUs (Wagner grade score < 3) and severe DFUs (Wagner grade score ≥ 3) based on Wagner classification. Patients were stratified according to the tertiles of TyG index. Logistic regression models were implemented to explore the association between TyG index and the severity of DFUs. Subgroup analyses were used to verify the reliability of results. RESULTS Compared with the reference lowest TyG tertile (T1), the highest tertile (T3) was associated with 0.377-fold increased risk of prevalence of severe DFUs (odds ratio [OR] 1.377, 95% confidence interval [CI] 1.017-1.865) (P = 0.039). After adjusting for potential confounders, the multivariable-adjusted OR and 95% CI were 1.506 (1.079-2.103) (P = 0.016) in patients with highest tertile. Moreover, subgroup analyses indicated that the association was stronger among men, patients with age ≥ 65 years, duration of diabetes more than 10 years, or without PAD. CONCLUSIONS Elevated TyG index is independently associated with severity of DFUs even after adjusting conventional confounders.

Abstract
The current study aimed to evaluate the effectiveness of peripheral blood mononuclear cell (PB-MNC) therapy as adjuvant treatment for patients with diabetic foot ulcers (DFUs) and no-option critical limb ischaemia (NO-CLI). The study is a prospective, noncontrolled, observational study including patients with neuro-ischaemic DFUs and NO-CLI who had unsuccessful revascularization below the ankle (BTA) and persistence of foot ischaemia defined by TcPO2 values less than 30 mmHg. All patients received three cycles of PB-MNC therapy administered through a "below-the-ankle approach" in the affected foot along the wound-related artery according to the angiosome theory. The primary outcome measures were healing, major amputation, and survival after 1 year of follow-up. The secondary outcome measures were the evaluation of tissue perfusion by TcPO2 and foot pain defined by the numerical rating scale (NRS). Fifty-five patients were included. They were aged >70 years old and the majority were male and affected by type 2 diabetes with a long diabetes duration (>20 years); the majority of DFUs were infected and nearly 90% were assessed as gangrene. Overall, 69.1% of patients healed and survived, 3.6% healed and deceased, 10.9% did not heal and deceased, and 16.4% had a major amputation. At baseline and after PB-MNC therapy, the TcPO2 values were 17 ± 11 and 41 ± 12 mmHg, respectively (p < 0.0001), while the pain values (NRS) were 6.8 ± 1.7 vs. 2.8 ± 1.7, respectively (p < 0.0001). Any adverse event was recorded during the PB-MNC therapy. Adjuvant PB-MNC therapy seems to promote good outcomes in patients with NO-CLI and neuro-ischaemic DFUs.

Amputation in diabetic foot ulcer: A treatment dilemma. World J Orthop 2023; 14:312-318.

Abstract
Diabetic foot is a clinical manifestation of diabetes with a wide range of symptoms, including ulceration, osteomyelitis, osteoarticular destruction, and gangrene, as a consequence of advanced disease. Some diabetic foot cases present general indications for amputation, including dead limb, threat to the patient’s life, pain, loss of function, or nuisance. Various tools have been introduced to help decision-making in amputation for diabetic foot. However, it remains a conundrum because diabetic foot involves multiple pathomechanisms and factors that hinder its outcomes. Sociocultural issues often impede treatment from the patient’s side. We reviewed different perspectives in diabetic foot management, particularly related to amputation. In addition to deciding whether to amputate, physicians should address amputation level, timing, and ways to avoid patient deconditioning. Surgeons should not be autocratic in these circumstances and should be aware of beneficence and maleficence when considering whether to amputate. The main goal should be improving the patients’ quality of life rather than preserving the limb as much as possible.

Understanding the multifaceted etiopathogenesis of foot complications in individuals with diabetes. World J Clin Cases 2023; 11:1669-1683. [PMID: 36970006 PMCID: PMC10037285 DOI: 10.12998/wjcc.v11.i8.1669] [Citation(s) in RCA: 4] [Impact Index Per Article: 4.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 12/07/2022] [Revised: 02/01/2023] [Accepted: 02/17/2023] [Indexed: 03/07/2023] Open
Abstract
Diabetes mellitus, a chronic disease of metabolism, is characterized by a disordered production or cellular utilization of insulin. Diabetic foot disease, which comprises the spectrum of infection, ulceration, and gangrene, is one of the most severe complications of diabetes and is the most common cause of hospitalization in diabetic patients. The aim of this study is to provide an evidence-based overview of diabetic foot complications. Due to neuropathy, diabetic foot infections can occur in the form of ulcers and minor skin lesions. In patients with diabetic foot ulcers, ischemia and infection are the main causes of non-healing ulcers and amputations. Hyperglycemia compromises the immune system of individuals with diabetes, leading to persistent inflammation and delayed wound healing. In addition, the treatment of diabetic foot infections is challenging due to difficulty in accurate identification of pathogenic microorganisms and the widespread issue of antimicrobial resistance. As a further complicating factor, the warning signs and symptoms of diabetic foot problems can easily be overlooked. Issues associated with diabetic foot complications include peripheral arterial disease and osteomyelitis; accordingly, the risk of these complications in people with diabetes should be assessed annually. Although antimicrobial agents represent the mainstay of treatment for diabetic foot infections, if peripheral arterial disease is present, revascularization should be considered to prevent limb amputation. A multidisciplinary approach to the prevention, diagnosis, and treatment of diabetic patients, including those with foot ulcers, is of the utmost importance to reduce the cost of treatment and avoid major adverse consequences such as amputation.

Abstract
Diabetic foot ulcer (DFU) is a debilitating and severe manifestation of uncontrolled and prolonged diabetes that presents as ulceration, usually located on the plantar aspect of the foot. Approximately 15% of individuals with diabetes will eventually develop DFU, and 14%-24% of them will require amputation of the ulcerated foot due to bone infection or other ulcer-related complications. The pathologic mechanisms underlying DFU are comprise a triad: Neuropathy, vascular insufficiency, and secondary infection due to trauma of the foot. Standard local and invasive care along with novel approaches like stem cell therapy pave the way to reduce morbidity, decrease amputations, and prevent mortality from DFU. In this manuscript, we review the current literature with focus on the pathophysiology, preventive options, and definitive management of DFU.

Etiology, Epidemiology, and Disparities in the Burden of Diabetic Foot Ulcers. Diabetes Care 2023; 46:209-221.

Abstract
Diabetic foot ulcers (DFU) are a major source of preventable morbidity in adults with diabetes. Consequences of foot ulcers include decline in functional status, infection, hospitalization, lower-extremity amputation, and death. The lifetime risk of foot ulcer is 19% to 34%, and this number is rising with increased longevity and medical complexity of people with diabetes. Morbidity following incident ulceration is high, with recurrence rates of 65% at 3-5 years, lifetime lower-extremity amputation incidence of 20%, and 5-year mortality of 50-70%. New data suggest overall amputation incidence has increased by as much as 50% in some regions over the past several years after a long period of decline, especially in young and racial and ethnic minority populations. DFU are a common and highly morbid complication of diabetes. The pathway to ulceration, involving loss of sensation, ischemia, and minor trauma, is well established. Amputation and mortality after DFU represent late-stage complications and are strongly linked to poor diabetes management. Current efforts to improve care of patients with DFU have not resulted in consistently lower amputation rates, with evidence of widening disparities and implications for equity in diabetes care. Prevention and early detection of DFU through guideline-directed multidisciplinary care is critical to decrease the morbidity and disparities associated with DFU. This review describes the epidemiology, presentation, and sequelae of DFU, summarizes current evidence-based recommendations for screening and prevention, and highlights disparities in care and outcomes.

Machine learning for the prediction of minor amputation in University of Texas grade 3 diabetic foot ulcers. PLoS One 2022; 17:e0278445.

Abstract
Minor amputations are performed in a large proportion of patients with diabetic foot ulcers (DFU) and early identification of the outcome of minor amputations facilitates medical decision-making and ultimately reduces major amputations and deaths. However, there are currently no clinical predictive tools for minor amputations in patients with DFU. We aim to establish a predictive model based on machine learning to quickly identify patients requiring minor amputation among newly admitted patients with DFU. Overall, 362 cases with University of Texas grade (UT) 3 DFU were screened from tertiary care hospitals in East China. We utilized the synthetic minority oversampling strategy to compensate for the disparity in the initial dataset. A univariable analysis revealed nine variables to be included in the model: random blood glucose, years with diabetes, cardiovascular diseases, peripheral arterial diseases, DFU history, smoking history, albumin, creatinine, and C-reactive protein. Then, risk prediction models based on five machine learning algorithms: decision tree, random forest, logistic regression, support vector machine, and extreme gradient boosting (XGBoost) were independently developed with these variables. After evaluation, XGBoost earned the highest score (accuracy 0.814, precision 0.846, recall 0.767, F1-score 0.805, and AUC 0.881). For convenience, a web-based calculator based on our data and the XGBoost algorithm was established (https://dfuprediction.azurewebsites.net/). These findings imply that XGBoost can be used to develop a reliable prediction model for minor amputations in patients with UT3 DFU, and that our online calculator will make it easier for clinicians to assess the risk of minor amputations and make proactive decisions.

What Went Wrong with VEGF-A in Peripheral Arterial Disease? A Systematic Review and Biological Insights on Future Therapeutics. J Vasc Res 2022; 59:381-393.

Abstract
BACKGROUND Of the 200 million patients worldwide affected by peripheral arterial disease (PAD), 4% will inevitably require major limb amputation. Previous systematic reviews presented a conflicting body of evidence in terms of vascular endothelial growth factor (VEGF) family member effects upon PAD natural progression. Despite that, modulation of intrinsic angiogenesis mechanisms targeting the VEGF family members still confers an attractive therapeutic target. The aim of the present study was to evaluate current evidence of VEGF modulation in the context of PAD. METHODS This is a systematic literature review conducted according to the PRISMA guidelines and registered under PROSPERO database [CRD42021285988]. Independent literature search was performed up to April 1, 2022, on six databases. A total of 22 eligible studies were identified [N: 3, interventional patient studies; N: 19, animal studies]. Animal studies were appraised by the SYRCLE risk of bias tool, while human participant studies were assessed by the Newcastle Ottawa scale. Overall, quality of evidence was deemed fair for both animal and human studies. Main study outcomes were percentage change of injured vessel lumen stenosis and neointimal area formation upon VEGF modulation (inhibition or activation) in comparison with control group. FINDINGS Nineteen animal models and three human participant studies were included in the systematic review and assessed separately. Positive modulation of VEGF-A in animal models resulted in a median decrease of 65.58% [95% CI 45.2; 71.87] in lumen stenosis [14 studies]. Furthermore, positive modulation of VEGF-A was found to reduce neointimal area proliferation by a median decrease of 63.41% [95% CI 41.6; 79.59] [14 studies]. Median end of study duration was 28 days [range: 14-84 days]. Data were insufficient to assess these outcomes with respect to VEGF-B or VEGF-C modulation. The limited number of available human studies presented inadequate outcome assessment despite their overall fair NOS grading. INTERPRETATION VEGF-A-positive modulation decreases lumen stenosis and neointimal hyperplasia in PAD simulation animal models. Previously identified variability among outcomes was found to strongly stem from the variability of experimental designs. Clinical applicability and safety profile of VEGF-A in the context of PAD remain to be defined by a robust and uniformly designed body of further animal model-based experiments.

Abstract
AIM The aim of the current study is to evaluate the association between below-the-ankle (BTA) arterial disease and coronary artery disease (CAD) in patients with diabetic foot ulcers (DFUs). METHODS The study group was composed of patients with an active neuro-ischaemic DFUs managed in a tertiary care diabetic foot clinic. All patients received a pre-set limb salvage protocol including lower limb revascularization. By a retrospective analysis of individual angiograms, patients were divided in two groups: below-the-ankle (BTA) and above-the-ankle (ATA) arterial disease groups. The rate of CAD at baseline assessment and the new events of acute myocardial ischaemia (AMI) during 1-year of follow-up were evaluated and compared between the two groups. RESULTS Two hundreds seventy-two (272) patients were included, 120 (44.1%) showed BTA arterial disease while 152 (55.9%) ATA arterial disease. The mean age was 68.9 ± 9.6 years, 198 (72.8%) were male, 246 (90.4%) had type 2 diabetes, the mean diabetes duration was 20.7 ± 11.6 years, the mean HbA1c was 7.8 ± 4.2% (62 ± 22 mmmol/mol). The whole population reported CAD in 172 cases (63.4%), and the rate in the BTA group was significantly higher than in ATA group, respectively, 90 (75.4%) vs 82 (54.1%), p < 0.0001. During the follow-up, BTA group had 5% of new cases of AMI in comparison to 1.3% in ATA group (p < 0.001). At the multivariate analysis BTA resulted an independent marker of CAD [OR 1.9 CI 9 5% (1.3-4.5) p = 0.0001]. CONCLUSION The current study shows a significant association between BTA arterial disease and CAD. A close cardiovascular screen should be required in patients with DFUs.

Geographic and Ethnic Inequalities in Diabetes-Related Amputations. FRONTIERS IN CLINICAL DIABETES AND HEALTHCARE 2022; 3:855168.

Abstract
Individuals with diabetes mellitus are at increasing risk for major lower-extremity amputations (LEAs). Poor quality of life and remarkable disabilities are associated with LEAs, determining a high economic burden for the healthcare systems. Reducing LEAs is therefore a primary marker of quality of care of the diabetic foot. At global level, between-countries comparisons of LEAs rates are basically hampered by differences in criteria used for data collection and analysis among studies. Significant variability in amputation rates exists between geographic areas, and also within specific regions of a country. Overall 5-year mortality rate after major amputations is reported to vary substantially across countries, from 50 to 80%. The odds of LEAs are substantially higher for Black, Native American and Hispanic ethnicities compared with White groups, with similar figures observed in the economically disadvantaged areas compared to more developed ones. Such discrepancies may reflect differences in diabetes prevalence as well as in financial resources, health-care system organization and management strategies of patients with diabetic foot ulcers. Looking at the experience of countries with lower rates of hospitalization and LEAs worldwide, a number of initiatives should be introduced to overcome these barriers. These include education and prevention programs for the early detection of diabetic foot at primary care levels, and the multidisciplinary team approach with established expertise in the treatment of the more advanced stage of disease. Such a coordinated system of support for both patients and physicians is highly required to reduce inequalities in the odd of diabetes-related amputations worldwide.
