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 Diabetic foot ulcer is a major medical, social, and economic problem, and a leading cause of hospitalisations, increased morbidity, and mortality. Despite a rising occurrence, there is a dearth of data on the incidence and its predictors. OBJECTIVE To assess the incidence and predictors of diabetic foot ulcers among patients with diabetes mellitus in a diabetic follow-up clinic in Central Ethiopia. DESIGN Retrospective follow-up study design. PARTICIPANTS A total of 418 newly diagnosed diabetes mellitus patients from 1 January 2012 to 31 December 2022. A computer-generated simple random sampling method was used to select the study participants. Data were collected using a structured data extraction checklist. The collected data were entered into Epi Info V.7.2 and exported to STATA V.14 for analysis. To estimate survival time, the Kaplan-Meier method was used, and the survival difference was tested using a log-rank test. OUTCOME MEASURES The Cox proportional hazard model was fitted to identify the predictors of diabetic foot ulcer development. The strength of the association was estimated using an adjusted hazard ratio (AHR) with a 95% confidence interval (CI), and statistical significance was proclaimed at a p<0.05. RESULT The overall incidence of diabetic foot ulcer was 1.51 cases (95% CI 1.03 to 2.22) per 100 person-years of observation. The cumulative incidence was 6.2% (95% CI 4.1% to 8.6%) over 10 years. The median time of follow-up was 45 months (IQR 21-73). Diastolic blood pressure of 90 mm Hg or above (AHR 2.91, 95% CI 1.25 to 6.77), taking combined medication (AHR 3.24, 95% CI 1.14 to 9.19) and having a peripheral arterial disease (AHR 5.26, 95% CI 1.61 to 17.18) were statistically significant predictors of diabetic foot ulcer development. CONCLUSION The risk of occurrence of diabetic foot ulcer was relatively high. Diastolic blood pressure level, combined medication and peripheral arterial disease were independent predictors of diabetic foot ulcer development. Hence, close monitoring and proper interventions are essential.

Abstract
Diabetic foot ulcer (DFU) is a well-known complication of diabetes and a significant burden on the national health systems. The neutrophil/lymphocyte ratio (NLR) and platelet/lymphocyte ratio are inexpensive and easily accessible biomarkers that have proved to be useful in several inflammatory, infectious and cardiovascular diseases. We carried out a comprehensive review examining the association of NLR and PLR with the onset and progression of DFU. PLR and NLR were significantly increased in patients with DFU, compared with a control group of T2DM patients without DFU, and correlate well with DFU severity, evaluated by Wagner and IWGDF grading scales. In patients with diabetic foot infections (DFI), elevated NLR and PLR were correlated with osteomyelitis, increased risk of amputation, and septic complications. The significance of the elevated value of these biomarkers in DFU is related to chronic hyperglycemia and low-grade systemic inflammation, atherosclerotic and vascular complications, and also the associated septic factor. Serial, dynamic follow-up can provide useful information in planning and monitoring DFU treatment, as well as in risk stratification of these vulnerable patients. Further randomized studies are needed to set the cut-off values with clinical significance.

Abstract
OBJECTIVE To systematically evaluate the risk factors for developing diabetic foot ulcers (DFU). METHODS The Cochrane Library, PubMed, Web of Science, SinoMed, CNKI, VIP, and Wanfang Data were searched for relevant studies on DFU risk factors, and the search time frame was from database creation to March 2022. Meta-analysis was performed using RevMan 5.3. RESULTS A total of 26 publications were included, including 3 cohort studies, 22 case-control studies, and one cross-sectional study. Meta-analysis showed that advanced age [MD = 6.04, 95% CI (3.92, 8.16)], male [OR = 1.84, 95% CI (1.48, 2.29)], elevated body mass index [MD = 1.58, 95% CI (0.47, 2.69)], prolonged duration of diabetes [MD = 2.72, 95% CI (2.33, 3.11)], comorbid nephropathy [OR = 3.15, 95% CI (2.68, 4.60)], comorbid neuropathy [OR = 4.80, 95% CI (2.79, 8.27)], comorbid retinopathy [OR = 3.37, 95% CI (2.26, 5.02)], elevated systolic blood pressure [OR = 8.19, 95% CI (6.33, 10.05)], elevated fasting glucose [MD = 1.60, 95% CI (0.21, 3.00)], elevated glycated hemoglobin [MD = 1.24, 95% CI (0.94, 1.54)], elevated triglycerides [MD = 0.44 (95% CI (0.15, 0.73)], elevated fibrinogen [MD = 1.35, 95% CI (0.62, 2.08)], elevated white blood cell count [MD = 2.56, 95% CI (2.24, 2.88)], elevated C-reactive protein [MD = 15.08, 95% CI (8.03, 22.13)], decreased ankle-brachial ratio [MD = -0.26, 95% CI (-0.36, -0.16)], and decreased total protein levels [MD = -4.58, 95% CI (-6.91, -2.25)] were risk factors for developing DFU (p < 0.05), and increased HDL cholesterol levels [MD = -0.22, 95% CI (-0.36, -0.08)] were protective factor for developing DFU (p < 0.05). CONCLUSION There are many risk factors for developing of ulcers in the diabetic feet, and early prevention and intervention should be performed as early as possible to assess the risk of developing diabetic foot patients.

PLoS One 2024; 19:e0301767. [PMID: 38758936 PMCID: PMC11101115 DOI: 10.1371/journal.pone.0301767] [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: 01/12/2024] [Accepted: 03/21/2024] [Indexed: 05/19/2024] Open
Abstract
The primary objective of this study was to isolate bacteria from diabetic foot ulcers and subsequently assess their antibiotic resistance capabilities. Seventy-five patients diagnosed with diabetic foot ulcers were investigated. A number of these patients (97.33%) had type 2 diabetes, with a significant proportion of them having been diagnosed for 1-5 years (29.33%). Notably, a substantial number of these individuals were on insulin usage (78.66%). Among the patients under examination, 49.33% reported having no use of tobacco products, alcohol, or betel leaf. The ulcers analyzed in this study were classified into grades 1-5 according to the Wagner scale. Wagner grade 2 diabetic foot ulcers had the highest number of culture-positive patients, at 33.33%. Pus samples collected from patients were cultured on selective media, and bacterial identity was confirmed by biochemical tests and polymerase chain reaction. A total of 141 isolates were isolated. Among the isolates, 82.97% gram-negative bacteria and 17.02% gram-positive bacteria were detected. Klebsiella pneumoniae was the most common isolate. Proteus spp., Escherichia coli, Pseudomonas aeruginosa, and Staphylococcus aureus were also detected. Approximately 61.33% of the ulcers exhibited were polybacterial. In this study, it was observed that all bacterial isolates, except for Proteus spp., were primarily detected in patients classified under Wagner's grade 2. Moreover, antibiotic susceptibility was also tested on these 141 isolates. Among them, Escherichia coli showed the highest multidrug resistance, 81.81%. Most of the gram-negative bacteria were resistant to ampicillin. All of the gram-negative isolates exhibited high levels of susceptibility to piperacillin-tazobactam, and these levels were Klebsiella pneumoniae (97.56%), Pseudomonas aeruginosa (95.24%), Escherichia coli (81.82%), and Proteus spp. (80%). On the other hand, gram-positive Staphylococcus aureus mostly showed sensitivity towards vancomycin and norfloxacin (79.17%).

Abstract
AIM/INTRODUCTION This study was designed as the second phase of a prospective cohort study to evaluate the incidence and risk factors of diabetic foot ulcers (DFU). MATERIALS AND METHODS The study was conducted in a university hospital in Iran. Each participant was checked and followed up for two years in terms of developing newfound DFU as ultimate outcome. We investigated the variables using univariate analysis and then by backward elimination multiple logistic regression. RESULTS We followed up 901 eligible patients with diabetes for two years. The mean age of the participants was 53.24 ± 11.46 years, and 58.53% of them were female. The two-year cumulative incidence of diabetic foot ulcer was 8% (95% CI 0.071, 0.089) [Incidence rate: 49.9 /1000 person-years]. However, the second-year incidence which was coincident with the COVID-19 pandemic was higher than the first-year incidence (4.18% and 1.8%, respectively). Based on our analysis, the following variables were the main risk factors for DFU incidence: former history of DFU or amputation [OR = 76.5, 95% CI(33.45,174.97), P value < 0.001], ill-fitting foot-wear [OR = 10.38, 95% CI(4.47,24.12), P value < 0.001], smoking [OR = 3.87,95%CI(1.28, 11.71),P value = 0.016], lack of preventive foot care [OR = 2.91%CI(1.02,8.29),P value = 0.045], and insufficient physical activity[OR = 2.25,95% CI(0.95,5.35),P value = 0.066]. CONCLUSION Overall, the two-year cumulative incidence of diabetic foot ulcer was 8% [Incidence rate: 49.9 /1000 person-years]; however, the second-year incidence was higher than the first-year incidence which was coincident with the COVID-19 pandemic (4.18% and 1.8%, respectively). Independent risk factors of DFU occurrence were prior history of DFU or amputation, ill-fitting footwear, smoking, lack of preventive foot care, and insufficient physical activity.

Abstract
Diabetes mellitus is a chronic disease affecting glucose metabolism. The pathophysiological reactions underpinning the disease can lead to the development of late diabetes complications. The gut microbiota plays important roles in weight regulation and the maintenance of a healthy digestive system. Obesity, diabetes mellitus, diabetic retinopathy, diabetic nephropathy and diabetic neuropathy are all associated with a microbial imbalance in the gut. Modern technical equipment and advanced diagnostic procedures, including xmolecular methods, are commonly used to detect both quantitative and qualitative changes in the gut microbiota. This review summarises collective knowledge on the role of the gut microbiota in both types of diabetes mellitus and their late complications, with a particular focus on diabetic foot syndrome.

Abstract
INTRODUCTION Prompt referral of patients with diabetic foot ulceration (DFU) to specialist services can lead to more timely assessment of these patients and subsequent improved rates of limb salvage and patient outcomes. In this study we wanted to determine the impact of education in the primary care setting on onward referrals to our specialist Diabetic Foot multi-disciplinary team (MDT) clinic. METHODS As part of a Diabetic Foot Roadshow, four teaching sessions were delivered in primary care settings across Shropshire by our specialist team from 17th March to the 25th May 2022. Attendees included podiatrists, tissue viability nurses, district nurses and wound care practitioners. Hospital records were used to identify all onward referrals to our Diabetic Foot MDT clinic in the weeks before and after delivery of the roadshow education sessions. RESULTS 184 referrals were made to the diabetic foot clinic from January to July 2022. There were 0.3 referrals per day in the months prior to the commencement of the education sessions, compared to 1.5 referrals per day following the commencement of the teaching sessions. This increase in referrals was statistically significant (p < 0.0001). CONCLUSION Teaching sessions delivered to community specialist healthcare professionals significantly increase onward referral of patients to specialist services, facilitating more timely assessment and management of patients with DFUs.

Abstract
AIMS Diabetic foot ulcer (DFU) is a leading cause of lower limb amputations in people with diabetes. This study was aimed to retrospectively analyze factors affecting DFU using real-world data from a large, prospective central-European diabetes registry (DPV [Diabetes-Patienten-Verlaufsdokumentation]). MATERIALS AND METHODS We matched adults with type 1 (T1D) or type 2 diabetes (T2D) and DFU to controls without DFU by diabetes type, age, sex, diabetes duration, and treatment year to compare possible risk factors. Cox regression was used to calculate hazard ratios for amputation among those with DFU. RESULTS In our cohort (N = 63 464), male sex, taller height, and diabetes complications such as neuropathy, peripheral artery disease, nephropathy, and retinopathy were associated with DFU (all p < .001). Glycated hemoglobin (HbA1c) was related to DFU only in T1D (mean with 95% confidence interval [CI]: 7.8 [6.9-9.0] % vs 7.5 [6.8-8.5] %, p < .001). High triglycerides and worse low-density lipoprotein/high-density lipoprotein ratio were also associated with DFU in T1D, whereas smoking (14.7% vs 13.1%) and alcohol abuse (6.4% vs 3.8%, both p < .001) were associated with DFU in T2D. Male sex, higher Wagner grades, and high HbA1c in both diabetes types and insulin use in T2D were associated with increased hazard ratios for amputations. CONCLUSIONS Sex, body height, and diabetes complications were associated DFU risk in adults with T1D and T2D. Improvement in glycemic control and lipid levels in T1D and reduction of smoking and drinking in T2D may be appropriate interventions to reduce the risk for DFU or amputations.

PVA/PVP Nanofibres Incorporated with Ecklonia cava Phlorotannins Exhibit Excellent Cytocompatibility and Accelerate Hyperglycaemic Wound Healing. Tissue Eng Regen Med 2024; 21:243-260. [PMID: 37865625 PMCID: PMC10825108 DOI: 10.1007/s13770-023-00590-5] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/06/2023] [Revised: 08/09/2023] [Accepted: 08/14/2023] [Indexed: 10/23/2023] Open
Abstract
BACKGROUND Diabetic foot ulcer (DFU) is a major debilitating complication of diabetes. The lack of effective diabetic wound dressings has been a significant problem in DFU management. In this study, we aim to establish a phlorotannin-incorporated nanofibre system and determine its potential in accelerating hyperglycaemic wound healing. METHODS The effective dose of Ecklonia cava phlorotannins (ECP) for hyperglycaemic wound healing was determined prior to phlorotannin nanofibre fabrication using polyvinyl-alcohol (PVA), polyvinylpyrrolidone (PVP), and ECP. Vapour glutaraldehyde was used for crosslinking of the PVA/PVP nanofibres. The phlorotannin nanofibres were characterised, and their safety and cytocompatibility were validated. Next, the wound healing effect of phlorotannin nanofibres was determined with 2D wound scratch assay, whereas immunofluorescence staining of Collagen-I (Col-I) and Cytokeratin-14 (CK-14) was performed in human dermal fibroblasts (HDF) and human epidermal keratinocytes (HEK), respectively. RESULTS Our results demonstrated that 0.01 μg/mL ECP significantly improved hyperglycaemic wound healing without compromising cell viability and proliferation. Among all nanofibres, PVA/PVP/0.01 wt% ECP nanofibres exhibited the best hyperglycaemic wound healing effect. They displayed a diameter of 334.7 ± 10.1 nm, a porosity of 40.7 ± 3.3%, and a WVTR of 1718.1 ± 32.3 g/m2/day. Besides, the FTIR spectra and phlorotannin release profile validated the successful vapour glutaraldehyde crosslinking and ECP incorporation. We also demonstrated the potential of phlorotannin nanofibres as a non-cytotoxic wound dressing as they support the viability and proliferation of both HDF and HEK. Furthermore, phlorotannin nanofibres significantly ameliorated the impaired hyperglycaemic wound healing and restored the hyperglycaemic-induced Col-I reduction in HDF. CONCLUSION Taken together, our findings show that phlorotannin nanofibres have the potential to be used as a diabetic wound dressing.

Makeri D, Eilu E, Odoki M, Agwu E. A Systematic Review of the Microbial Landscape of Diabetic Foot Ulcers in Uganda. Infect Drug Resist 2024; 17:143-151. [PMID: 38234374 PMCID: PMC10793123 DOI: 10.2147/idr.s446838] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/27/2023] [Accepted: 01/10/2024] [Indexed: 01/19/2024] Open
Abstract
Background Diabetes is a growing health concern globally. Poorly managed diabetes may result in diabetic foot ulcers (DFU), which can become a source of chronic infection known as diabetic foot infections. The increasing trend of diabetes in Uganda speaks to the potential for diabetic foot ulcers which may eventually become infected and their attendant impact on the quality of life of diabetic patients. This review assesses the microbial diversity of DFUs in Uganda, aiming to guide treatment and identify research gaps. Main Body of the Abstract We searched PubMed, Scopus and Embase for studies conducted in Uganda that reported isolating microorganisms from diabetic foot ulcers. Following the preferred reporting items for systematic reviews and meta-analysis (PRISMA), we included two eligible studies that reported isolating 122 bacteria spread across eleven (11) species using swab samples and conventional culture methods. Significant isolates included World Health Organization priority pathogens including: Enterobacter specie, Staphylococcus aureus, Klebsiella pneumoniae, and Acinetobacter specie. Methicillin resistant Staphylococcus aureus (MRSA) constituted 33.3% of Staphylococci species and 26% of all bacterial isolates while extended-spectrum beta-lactamase producing Escherichia coli and Klebsiella specie constituted 14.29% of total microbial isolates. Most bacteria showed susceptibility to Imipenem, Vancomycin, Ciprofloxacin, and Clindamycin, but resistance to Cotrimoxazole and Ampicillin was noted. Short Conclusion We conclude that data on the microbiology of DFUs in Uganda is scarce; however, the bioburden of DFUs in the country is similar to those in other parts of the world, and MRSA poses a challenge to antibiotic therapy. Consequently, the continued use of swab samples and conventional culture and sensitivity methods may limit the isolation, identification, and presentation of other important isolates. We recommend characterization of bacterial isolates to better understand their genetic makeup, and the development of a national guideline for managing diabetic foot infections.

Abstract
Diabetic foot ulcers affect quality of life and economically burden patients and the Indonesian healthcare system. The comparative cost-effectiveness of wound care specialists in private practices (e.g., wound clinics) and wound care nurses in national hospitals remains unknown. Thus, we used a decision tree to compare the cost and healing rates for patients after 12 weeks of wound care. Uncertainty was addressed using one-way and probabilistic sensitivity analyses. Among 89 participants (42 in the national hospital and 47 in the private practice), no significant differences were observed between the two groups in terms of sex, age, education level, smoking status, duration of diabetes, Wagner wound classification, glycated haemoglobin levels, neuropathy status, ankle-brachial index, baseline characteristics, quality of life, DMIST (depth, maceration, inflammation/infection, size, tissue type of the wound bed, type of wound edge, and tunnelling/undermining) score and wound location (p > 0.05). However, significant differences were observed for days from first visit/assessment until complete healing, mean quality of life (p ≤ 0.001) and wound size (p = 0.047). Wound care specialists in private practices had a significantly lower cost of 2,804,423.3 Indonesian rupiah compared to 6,483,493.4 Indonesian rupiah for wound care nurses in national hospitals. The incremental cost-effectiveness ratio was -165,723.9. Therefore, wound care specialists in private practices are more cost-effective for managing diabetic foot ulcers. Probability sensitivity analysis confirmed that 80%-90% of the scenarios were cost-effective. These findings may inform healthcare resource allocation in Indonesia. Additionally, evidence-based cost-effectiveness measures were strengthened in private practices and national hospitals.

Nasal MRSA carriage is a risk factor for development of antibiotic resistance in diabetic foot ulcers and is significantly higher than diabetic and non-diabetic individuals without foot ulcer. BMC Infect Dis 2023; 23:729. [PMID: 37884870 PMCID: PMC10601299 DOI: 10.1186/s12879-023-08673-3] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/17/2023] [Accepted: 10/06/2023] [Indexed: 10/28/2023] Open
Abstract
BACKGROUND Diabetic foot ulcer (DFU) is a major complication of diabetes often impacted by polymicrobial infection in the wound site. Diabetic patients are immunocompromised in nature and hence vulnerable to infection once the skin barrier is breached. Microbiological culture-based methods show that Staphylococcus aureus (SA) is the most frequently isolated bacteria from the DFU wounds. SA and its most clinically important antibiotic resistant variant methicillin-resistant S. aureus (MRSA) are commonly found in the nasal vestibule and colonization of SA as well as MRSA in any wound site can aggravate the condition. We hypothesize that the presence of nasal MRSA carriage can serve as a potential risk factor contributing to the emergence of antibiotic resistance in diabetic foot ulcer wounds. METHODS In the present study, we have compared the carriage of SA and MRSA in nasal cavity and foot skin among DFU patients (D+F+, n = 50), diabetic patients without any ulcer (D+F-, n = 50), and healthy controls (D-F-, n = 40) by using bacterial culture and PCR based methods. The D+F+, D+F- and D-F-individuals were further categorized based on the presence or absence of MRSA and clinical parameters were compared between MRSA+ ve and MRSA-ve individuals in each of the three groups mentioned above. RESULTS Our results show that, (a) nasal MRSA carriage is significantly higher (p < 0.05) in D+F+ group than the D+F- and D-F- and significantly associated with wound MRSA carriage in D+ F+ individuals (O.R. = 4.09; 95% C.I. = 1.12-15.05) and (b) the HbA1C level is significantly higher (p < 0.02) in wound MRSA positive, compared to MRSA negative D+F+ patients. Interestingly more than half of the MRSA (64%) isolated from DFU wound were identified to be multidrug resistant. CONCLUSION These findings strongly suggest that nasal MRSA carriage can act as a risk factor for development of antibiotic resistance in diabetic foot ulcers and it is therefore important to screen nasal and wound sites of these patients regularly. We have also developed a rapid multiplex PCR assay to detect MRSA from clinical isolates or microbial DNA isolated from clinical samples in the hospital settings.

Foot (Edinb) 2023; 56:102000. [PMID: 36905796 DOI: 10.1016/j.foot.2023.102000] [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: 04/01/2022] [Revised: 02/16/2023] [Accepted: 03/05/2023] [Indexed: 03/13/2023]
Abstract
OBJECTIVE This study aimed to determine whether the prolonged duration of diabetic foot ulcers was associated with an increased incidence of diabetic foot osteomyelitis. STUDY DESIGN A retrospective cohort study METHODS: The medical records of all patients who participated in the diabetic foot clinic between January 2015 and December 2020 were reviewed. Patients with new diabetic foot ulcers were monitored for diabetic foot osteomyelitis. The collected data included the patient's profile, comorbidities and complications, the ulcer profile (area, depth, location, duration, number of ulcers, inflammation, and history of the previous ulcer), and outcome. Univariate and multivariate Poisson regression analyses were used to assess risk variables for diabetic foot osteomyelitis. RESULTS Eight hundred and fifty-five patients were enrolled; 78 developed diabetic foot ulcers (cumulative incidence 9% over 6 years, average annual incidence 1.5%) and among these diabetic foot ulcers, 24 developed diabetic foot osteomyelitis (cumulative incidence 30% over 6 years, average annual incidence of 5%, incidence rate 0.1/person-year). Statistically significant risk factors for the development of diabetic foot osteomyelitis were ulcers that were deep to the bone (adjusted risk ratio 2.50, p = 0.04) and inflamed wounds (adjusted risk ratio 6.20, p = 0.02). The duration of diabetic foot ulcers was not associated with diabetic foot osteomyelitis (adjusted risk ratio 1.00, p = 0.98). CONCLUSION The duration was not an associated risk factor for diabetic foot osteomyelitis, while bone-deep ulcers and inflamed ulcers were found to be significant risk factors for the development of diabetic foot osteomyelitis.

Abstract
This study aimed to investigate the efficacy of using routinely collected clinical data in predicting the risk of diabetic foot ulcer (DFU). The first objective was to develop a prognostic model based on the most important risk factors objectively selected from a set of 39 clinical measures. The second objective was to compare the prediction accuracy of the developed model against that of a model based on only the 3 risk factors that were suggested in the systematic review and meta-analyses study (PODUS). In a cohort study, a set of 12 continuous and 27 categorical data from patients (n = 203 M/F:99/104) who attended a specialised diabetic foot clinic were collected at baseline. These patients were then followed-up for 24 months during which 24 (M/F:17/7) patients had DFU. Multivariate logistic regression was used to develop a prognostic model using the identified risk factors that achieved p < 0.2 based on univariate logistic regression. The final prognostic model included 4 risk factors (Adjusted-OR [95% CI]; p) in total. Impaired sensation (116.082 [12.06-1117.287]; p = 0.000) and presence of callus (6.257 [1.312-29.836]; p = 0.021) were significant (p < 0.05), while having dry skin (5.497 [0.866-34.89]; p = 0.071) and Onychomycosis (6.386 [0.856-47.670]; p = 0.071) that stayed in the model were not significant. The accuracy of the model with these 4 risk factors was 92.3%, where sensitivity and specificity were 78.9%, and 94.0% respectively. The 78.9% sensitivity of our prognostic 4-risk factor model was superior to the 50% sensitivity that was achieved when the three risk factors proposed by PODUS were used. Also our proposed model based on the above 4 risk factors showed to predict the DFU with higher overall prognostic accuracy. These findings have implications for developing prognostic models and clinical prediction rules in specific patient populations to more accurately predict DFU.

Abstract
Strategies have been researched and implemented to reduce the number of people with diabetic foot ulcers (DFUs). One problem is the accurate assessment of DFU severity, which is the main factor in resource allocation and treatment choice. The primary objective of this study was to assess pentraxin-3 as a biomarker of an infected DFU (IDFU), the limb amputation level prognosis, and patient survival. The secondary objectives were to evaluate and compare other markers, including white blood cells (WBCs), C-reactive protein (CRP), the erythrocyte sedimentation rate (ESR), and procalcitonin (PCT), for identifying IDFUs. Over a period of two years, 145 patients were followed; 131 of these were analyzed for this study. Pentraxin-3 was found to be a good predictor of death (p = 0.047). A comparison between IDFUs and DFUs revealed the following differences: PCT had the highest AUROC of 0.91, sensitivity of 93.7, and specificity of 83.3%. CRP had a cutoff value of 226 mg/L, an AUROC of 0.89, a sensitivity of 95.5%, and a specificity of 83.3%. Fibrinogen had an AUROC of 0.87 at a cutoff value of 5.29 g/L, with a good sensitivity and specificity of 85% and 87%, respectively. ESR had a cutoff value of 46 mm/h, an AUROC of 85%, a sensitivity of 83.7%, and a specificity of 83.3%. Pentraxin-3 showed promising results in predicting IDFUs and DFUs, and it served as a marker for the risk of death in IDFU patients during the 6 month follow-up. Other markers, including CRP, PCT, ESR, and fibrinogen, were more effective in differentiating between IDFUs and DFUs.

Abstract
OBJECTIVE to analyze the effects of educational technologies in the prevention and treatment of diabetic ulcers. METHOD a systematic review conducted in seven databases, a bibliographic index, an electronic library and the Gray Literature. The sample consisted of 11 randomized controlled clinical trials. The synthesis of the results was descriptive and through meta-analysis. RESULTS the predominant educational technologies were training sessions and verbal guidelines, with soft-hard technologies standing out. When compared to usual care, the educational technologies presented a protective factor to prevent the incidence of diabetic ulcers (RR=0.40; 95% CI=0.18-0.90; p=0.03) and the certainty of the evidence assessment was low. The educational technologies also had a protective factor to prevent the incidence of lower limb amputations (RR=0.53; 95% CI=0.31-0.90; p=0.02) and certainty of the evidence was very low. CONCLUSION soft-hard educational technologies such as structured verbal guidelines, educational games, lectures, theoretical-practical training sessions, educational videos, folders, serial albums and playful drawings, and hard technologies such as therapeutic footwear, insoles, infrared digital thermometer, foot care kits, Telemedicine app and mobile phone use, were effective for the prevention and treatment of diabetic ulcers, although more robust studies are required.

Abstract
One of the most notable required features of wound healing is the enhancement of angiogenesis, which aids in the acceleration of regeneration. Poor angiogenesis during diabetic wound healing is linked to a shortage of pro-angiogenic or an increase in anti-angiogenic factors. As a result, a potential treatment method is to increase angiogenesis promoters and decrease suppressors. Incorporating microRNAs (miRNAs) and small interfering RNAs (siRNAs), two forms of quite small RNA molecules, is one way to make use of RNA interference. Several different types of antagomirs and siRNAs are now in the works to counteract the negative effects of miRNAs. The purpose of this research is to locate novel antagonists for miRNAs and siRNAs that target multiple genes to promote angiogenesis and wound healing in diabetic ulcers.In this context, we used gene ontology analysis by exploring across several datasets. Following data analysis, it was processed using a systems biology approach. The feasibility of incorporating the proposed siRNAs and miRNA antagomirs into polymeric bioresponsive nanocarriers for wound delivery was further investigated by means of a molecular dynamics (MD) simulation study. Among the three nanocarriers tested (Poly (lactic-co-glycolic acid) (PLGA), Polyethylenimine (PEI), and Chitosan (CTS), MD simulations show that the integration of PLGA/hsa-mir-422a is the most stable (total energy = -1202.62 KJ/mol, Gyration radius = 2.154 nm, and solvent-accessible surface area = 408.416 nm2). With values of -25.437 KJ/mol, 0.047 nm for the Gyration radius, and 204.563 nm2 for the SASA, the integration of the second siRNA/ Chitosan took the last place. The results of the systems biology and MD simulations show that the suggested RNA may be delivered through bioresponsive nanocarriers to speed up wound healing by boosting angiogenesis.

Abstract
AIMS This study aimed to identify demographic, clinical, and psychological contributors to DFU healing and favorable healing process. METHODS Patients with a chronic DFU were evaluated at baseline (T0; n = 153), two months later (T1; n = 108), and six months later (T2; n = 71). Patients were evaluated on health literacy, perceived stress, anxiety, depression, and illness perceptions. Cox proportional hazard models were built to analyze the predictors of DFU healing and favorable healing process (wound area reduction), including the assessment of time to achieve those outcomes. RESULTS More than half of patients had their DFU healed (56.1%) or showed a favorable healing process (83.6%). Median time for healing was 112 days, while for favorable process was 30 days. Illness perceptions were the only predictor of wound healing. Being female , with adequate health literacy, and a first DFU predicted a favorable healing process. CONCLUSIONS This is the first study showing that beliefs about DFU are significant predictors of DFU healing, and that health literacy is a significant predictor of a favorable healing process. Brief, comprehensive interventions should be implemented, at the treatment initial stage, in order to change misperceptions and to promote DFU literacy and better health outcomes.

[PMID: 37252574 PMCID: PMC10212749 DOI: 10.7759/cureus.38123] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/24/2023] [Accepted: 04/25/2023] [Indexed: 05/31/2023] Open
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
Chronic nonhealing heel ulcerations have been established as an independent risk factor for major amputation, with poor rates of limb salvage success. Partial calcanectomy is a controversial limb salvage procedure reserved for patients with these heel ulcerations. We conducted a retrospective cohort study reviewing 39 limbs that underwent a partial calcanectomy from 2012 to 2018 to evaluate the proportion of patients healed, time to healing, ulcer recurrence, and postoperative functional level compared to the preoperative state. In addition, age, gender, body mass index, smoking status, coronary artery disease, diabetes mellitus, renal insufficiency, dialysis, peripheral arterial disease, method of closure, and percent of calcaneus resected were evaluated. Mean follow-up for our cohort was 2.3 years. We had a 1 year mortality rate of 11%, and a major amputation rate of 18%. Our results demonstrated a 77% healing rate with a median time to healing of 162 days. We found that patients who were closed primarily had a faster time to healing compared to patients who underwent closure by secondary intention. Our data showed that ulcer recurrence developed in 57% of healed limbs. We found that 76% of our patients were ambulatory postoperatively. These results suggest that partial calcanectomy is a viable limb salvage procedure with a predictable level of ambulation and function in a high-risk patient population.

Abstract
Objective This is a case series study of 14 cases of chronic unhealed ulcers involving patients of 19-85 years, aimed to demonstrate the positive therapeutic outcomes of using autologous platelet rich plasma (PRP) in diabetic foot ulcer (DFU) and other chronic wound healing. Methods This is a formal consecutive clinical case series. Patients with chronic unhealed ulcers were enrolled from the amputation prevention clinic by an interdisciplinary team includes podiatrist, general surgeon, orthopedic, vascular surgeon, and wound care nurses at Kahel Specialized Centre, a specialized center for managing foot and ankle diseases, located in Riyadh, Saudi Arabia. Those patients who presented with chronic wounds and showed no significant wound reduction despite following the standard wound care protocol were included in the study. There were no specific predetermined exclusion criteria when considering patients for treatment with this modality. Results In this case series, majority (80%) of the patients were above 50 years of age, and 10 (66.7%) patients were male and 5 (33.3%) were female. Of all the cases presented to the amputation prevention clinic, majority (73.3%) reported suffering from type 2 diabetes mellitus (DM) and also, one reported type 1 DM [6.7%]). All the cases of DFU received a combination of hydrogel and autologous PRP treatment and were put of suitable offloading devices, except one case received a combination of Cadexomer iodine, hydrogel and PRP treatment. In the present case series involving 3-14 weeks of the treatment duration, only 2-3 doses of autologous PRP provided complete healing and or maximum wound closure. Conclusion Autologous PRP therapy is efficacious in facilitating, enhancing wound healing and aids in complete wound closure. This case series was limited in term of the sample size which is the number patients enrolled for the study, hence, the study finding remain inconclusive to some extent and hence, further study is required with greater number of sample size. The strength of this study is that it is the first study in Saudi Arabia and gulf region, to report the beneficial effect of PRP in chronic unhealed ulcers including diabetic ulcers.

Abstract
Chronic wounds, particularly those associated with diabetes mellitus, represent a growing threat to public health, with additional notable economic impacts. Inflammation associated with these wounds leads to abnormalities in endogenous electrical signals that impede the migration of keratinocytes needed to support the healing process. This observation motivates the treatment of chronic wounds with electrical stimulation therapy, but practical engineering challenges, difficulties in removing stimulation hardware from the wound site, and absence of means to monitor the healing process create barriers to widespread clinical use. Here, we demonstrate a miniaturized wireless, battery-free bioresorbable electrotherapy system that overcomes these challenges. Studies based on a splinted diabetic mouse wound model confirm the efficacy for accelerated wound closure by guiding epithelial migration, modulating inflammation, and promoting vasculogenesis. Changes in the impedance provide means for tracking the healing process. The results demonstrate a simple and effective platform for wound site electrotherapy.

Abstract
Advances in wound treatment depend on the availability of animal models that reflect key aspects of human wound healing physiology. To this date, the accepted mouse models do not reflect defects in the healing process for chronic wounds that are associated with type two diabetic skin ulcers. The long term, systemic physiologic stress that occurs in middle aged or older Type 2 diabetes patients is difficult to simulate in preclinical animal model. We have strived to incorporate the essential elements of this stress in a manageable mouse model: long term metabolic stress from obesity to include the effects of middle age and thereafter onset of diabetes. At six-weeks age, male C57BL/6 mice were separated into groups fed a chow and High-Fat Diet for 0.5, 3, and 6 months. Treatment groups included long term, obesity stressed mice with induction of diabetes by streptozotocin at 5 months, and further physiologic evaluation at 8 months old. We show that this model results in a severe metabolic phenotype with insulin resistance and glucose intolerance associated with obesity and, more importantly, skin changes. The phenotype of this older age mouse model included a transcriptional signature of gene expression in skin that overlapped that observed with elderly patients who develop diabetic foot ulcers. We believe this unique old age phenotype contrasts with current mice models with induced diabetes.

Abstract
Introduction In Egypt, diabetic foot ulcers markedly contribute to the morbidity and mortality of diabetic patients. Accurately predicting the risk of diabetic foot ulcers could dramatically reduce the enormous burden of amputation. Objective The aim of this study is to design an artificial intelligence-based artificial neural network and decision tree algorithms for the prediction of diabetic foot ulcers. Methods A case-control study design was utilized to fulfill the aim of this study. The study was conducted at the National Institute of Diabetes and Endocrine Glands, Cairo University Hospital, Egypt. A purposive sample of 200 patients was included. The tool developed and used by the researchers was a structured interview questionnaire including three parts: Part I: demographic characteristics; Part II: medical data; and Part III: in vivo measurements. Artificial intelligence methods were used to achieve the aim of this study. Results The researchers used 19 significant attributes based on medical history and foot images that affect diabetic foot ulcers and then proposed two classifiers to predict the foot ulcer: a feedforward neural network and a decision tree. Finally, the researchers compared the results between the two classifiers, and the experimental results showed that the proposed artificial neural network outperformed a decision tree, achieving an accuracy of 97% in the automated prediction of diabetic foot ulcers. Conclusion Artificial intelligence methods can be used to predict diabetic foot ulcers with high accuracy. The proposed technique utilizes two methods to predict the foot ulcer; after evaluating the two methods, the artificial neural network showed a higher improvement in performance than the decision tree algorithm. It is recommended that diabetic outpatient clinics develop health education and follow-up programs to prevent complications from diabetes.

Abstract
The prevalence of diabetes has increased dramatically over the past decade, especially in developing countries, reaching pandemic proportions. Although has been the most important factor influencing the prevalence of type 2 diabetes, the prevalence of type 2 diabetes is on the increase among younger adults. The subsequent rate of increase with age is variable, which is more evident in societies where the general prevalence of the disease is higher. Based on clinical and statistical data obtained from the patients who were admitted to The First and Second Surgery Wards in the Sibiu County Emergency University Clinical Hospital (Sibiu, Romania) and the Proctoven Clinic (Sibiu, Romania) between January 2018 and December 2020, the present study attempted to devise a risk score that can be applied for the benefit of patients. The ultimate aim was that this risk score may be eventually applied by diabetologists and surgeons to assess the risk of amputation in patients with diabetic foot lesions. An important part in the therapeutic management of diabetic foot injuries is the assessment of risk factors. Using this risk score system devised, the risk factors that were found to exert influence in aggravating diabetic foot injuries are smoking, obesity, dyslipidaemia, unbalanced diabetes mellitus (glycated haemoglobin ≥7.5%), duration of diabetes >5 years, hepatic steatosis and the co-existence of various heart diseases. To conclude, all these risk factors aforementioned can decrease the effectiveness of treatment and can have a significant impact on the quality of life, if they are not well known.

Abstract
Diabetic foot complications have multiple adverse effects in a person's quality of life. Yet, efficient monitoring schemes can mitigate or postpone any disorders, mainly by early detecting regions of interest. Nowadays, optical sensors and artificial intelligence (AI) tools can contribute efficiently to such monitoring processes. In this work, we provide information on the adopted imaging schemes and related optical sensors on this topic. The analysis considers both the physiology of the patients and the characteristics of the sensors. Currently, there are multiple approaches considering both visible and infrared bands (multiple ranges), most of them coupled with various AI tools. The source of the data (sensor type) can support different monitoring strategies and imposes restrictions on the AI tools that should be used with. This review provides a comprehensive literature review of AI-assisted DFU monitoring methods. The paper presents the outcomes of a large number of recently published scholarly articles. Furthermore, the paper discusses the highlights of these methods and the challenges for transferring these methods into a practical and trustworthy framework for sufficient remote management of the patients.

Incidence and predictor of diabetic foot ulcer and its association with change in fasting blood sugar among diabetes mellitus patients at referral hospitals in Northwest Ethiopia, 2021. PLoS One 2022; 17:e0274754. [PMID: 36227947 PMCID: PMC9560537 DOI: 10.1371/journal.pone.0274754] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/24/2022] [Accepted: 09/05/2022] [Indexed: 11/05/2022] Open
Abstract
Background Diabetes mellitus is one of the global public health problems and fasting blood sugar is an important indicator of diabetes management. Uncontrolled diabetes can lead to diabetic foot ulcers, which is a common and disabling complication. The association between fasting blood glucose level and the incidence of diabetic foot ulcers is rarely considered, and knowing its predictors is good for clinical decision-making. Therefore, the aim of this study was to determine the incidence and predictors of diabetic foot ulcers and its association with changes in fasting blood sugar among diabetes mellitus patients at referral hospitals in Northwest Ethiopia. Methods A multicenter retrospective follow-up study was conducted at a referral hospital in Northwest Ethiopia. A total of 539 newly diagnosed DM patients who had follow-up from 2010 to 2020 were selected using a computer-generated simple random sampling technique. Data was entered using Epi-Data 4.6 and analyzed in R software version 4.1. A Cox proportional hazard with a linear mixed effect model was jointly modeled and 95% Cl was used to select significant variables. AIC and BIC were used for model comparison. Result A total of 539 diabetes patients were followed for a total of 28727.53 person-month observations. Overall, 65 (12.1%) patients developed diabetic foot ulcers with incidence rate of 2.26/1000-person month observation with a 95% CI of [1.77, 2.88]. Being rural (AHR = 2.30, 95%CI: [1.23, 4.29]), being a DM patient with Diabetic Neuropathy (AHR = 2.61, 95%CI: [1.12, 6.06]), and having peripheral arterial disease(PAD) (AHR = 2.96, 95%CI: [1.37, 6.40]) were significant predictors of DFU. The time-dependent lagged value of fasting blood sugar change was significantly associated to the incident of DFU (α = 1.85, AHR = 6.35, 95%CI [2.40, 16.79]). Conclusion and recommendation In this study, the incidence of DFU was higher than in previous studies and was influenced by multiple factors like rural residence, having neuropathy, and PAD were significant predictors of the incidence of DFU. In addition, longitudinal changes in fasting blood sugar were associated with an increased risk of DFU. Health professionals and DM patients should give greater attention to the identified risk factors for DFU were recommended.

Abstract
The appropriate treatment of the common diabetic foot ulcers (DFUs) in diabetic patients demands enormous human, organizational and financial resources that are finite. Interdisciplinary teams of medical and surgical specialists, as well as allied health professionals, can help to reduce the consumption of these resources, optimize treatment, and prevent DFUs. They consist primarily of vascular surgeons, endocrinologists, and orthopedic foot and ankle surgeons and are closely supported when required by infectious diseases specialists, plastic surgeons, wound care specialist nurses, podiatrists, and orthotists. A timely interdisciplinary team review in each clinic session decreases the number of hospital visits for the oftentimes-handicapped diabetic patients significantly. The interdisciplinary team clinic setup has also been shown to reduce the risk of amputations, length of hospital staz and mortality rates.

Abstract
INTRODUCTION Diabetic Foot (DF) is a prevalent metabolic infection. DF wounds are the basis for all cases of non-traumatic lower limbs amputations in diabetes. DF care approaches include debridement of wound, pressure relief in the wounded area, proper wound, infection and ischemia management. However, there is a need for research to develop more effective therapeutic approaches. This study investigated the effectivity and safety of autologous platelet-rich gel combined with conventional treatment and traditional Chinese medicine (TCM) in diabetic foot ulcers therapy. METHODS Sixty diabetic foot ulcer patients were divided into treatment and control groups of 30 patients each. The treatment group involved a combination of autologous platelet-rich gel, conventional treatment, and TCM. The control group was only treated with a combination of conventional therapy and TCM. Laboratory variables, including platelets, hemoglobin, albumin, and HbA1c, were analyzed and compared between treatment and control groups at baseline and end-point. Healing area, volume, and rates were compared in both groups. RESULTS basic patients' data and the wound conditions had no significant difference between treatment and control group. The treatment and control groups cure rates were 93.3% vs. 50%, respectively. The healing rate per two weeks was significantly higher in the treatment than in control group (0.78±0.05 vs. 0.43±0.04). There was no statistically significant difference in the platelets, hemoglobin, albumin, and HbA1c levels in the treatment and control groups. CONCLUSION Autologous platelet-rich gel combined with conventional treatment and traditional Chinese medicine (TCM) is effective and safe for diabetic foot ulcers treatment.

Abstract
Over the last decades, three-dimensional (3D) organotypic skin models have received enormous attention as alternative models to in vivo animal models and in vitro two-dimensional assays. To date, most organotypic skin models have an epidermal layer of keratinocytes and a dermal layer of fibroblasts embedded in an extracellular matrix (ECM)-based biomaterial. The ECM provides mechanical support and biochemical signals to the cells. Without advancements in ECM-based biomaterials and biofabrication technologies, it would have been impossible to create organotypic skin models that mimic native human skin. In this review, the use of ECM-based biomaterials in the reconstruction of skin models, as well as the study of complete ECM-based biomaterials, such as fibroblasts-derived ECM and decellularized ECM as a better biomaterial, will be highlighted. We also discuss the benefits and drawbacks of several biofabrication processes used in the fabrication of ECM-based biomaterials, such as conventional static culture, electrospinning, 3D bioprinting, and skin-on-a-chip. Advancements and future possibilities in modifying ECM-based biomaterials to recreate disease-like skin models will also be highlighted, given the importance of organotypic skin models in disease modeling. Overall, this review provides an overview of the present variety of ECM-based biomaterials and biofabrication technologies available. An enhanced organotypic skin model is expected to be produced in the near future by combining knowledge from previous experiences and current research.

Abstract
This study aimed to review epidemiology of diabetic foot (DF) amputation and provide a pooled estimation of DF amputation rate in the region. A comprehensive search was performed in Web of Science, PubMed, Scopus and EMBASE databases using appropriate search term. Obtained records were entered endnote software and after removing duplicats were screened by title, abstract and full text. Data was extracted from the remained documents. Random effect meta-analysis was used to pool the estimated prevalence rate due to sever heterogeneity between studies. Finally 17 articles in diabetes, 20 in patients with DFU (diabetic foot ulcer) and two in both remained after screening and included in meta-analysis. Overall pooled amputation rate in diabetes was 2% (95% CI: 1%-3%) which was not significantly different between countries. The pooled prevalence of amputation rate in DFU patients was 33% (24%-43%) and the pooled prevalence in Saudi Arabia was significantly higher than in other countries. The estimated rate of foot amputation in diabetes patients and those with DFUs in the Middle East region is approximately high, which may indicate low quality of preventive foot care, low socioeconomics and low patients awareness or education in countries with high amputation rate.

Abstract
AIM We aimed to compare the mortality of individuals at low, moderate, and high risk of diabetic foot disease (DFD) in the context of newly diagnosed type 2 diabetes, before developing active diabetic foot problem. METHODS This was a population-based cohort study of adults with newly diagnosed type 2 diabetes utilizing IQVIA Medical Research Data. The outcome was all-cause mortality among individuals with low, moderate, and high risk of DFD, and also in those with no record of foot assessment and those who declined foot examination. RESULTS Of 225,787 individuals with newly diagnosed type 2 diabetes, 34,061 (15.1%) died during the study period from January 1, 2000 to December 31, 2019. Moderate risk and high risk of DFD were associated with increased mortality risk compared to low risk of DFD (adjusted hazard ratio [aHR] 1.50, 95% CI 1.42, 1.58; aHR 2.01, 95% CI 1.84, 2.20, respectively). Individuals who declined foot examination or who had no record also had increased mortality risk of 75% and 25% vs. those at low risk of DFD, respectively (aHR 1.75, 95% CI 1.51, 2.04; aHR 1.25, 95% CI 1.20, 1.30). CONCLUSION Individuals with new-onset type 2 diabetes who had moderate to high risk of DFD were more likely to die compared to those at low risk of DFD. The associations between declined foot examination and absence of foot examinations, and increased risk of mortality further highlight the importance of assessing foot risk as it identifies not only patients at risk of diabetic foot ulceration but also mortality.

Abstract
Aim The aim of this study was to analyze changes in the incidence, management and mortality of DFU in Sicilian Type 2 diabetic patients hospitalized between two eras, i.e. 2008–2013 and 2014–2019. Methods We compared the two eras, era1: 2008–13, era2: 2014–19. In era 1, n = 149, and in era 2, n = 181 patients were retrospectively enrolled. Results In the population hospitalized for DFU in 2008–2013, 59.1% of males and 40.9% of females died, whilst in 2014–2019 65.9% of males and 34.1% of females died. Moderate chronic kidney disease (CKD) was significantly higher in patients that had died than in ones that were alive (33% vs. 43%, p < 0.001), just as CKD was severe (14.5% vs. 4%, p < 0.001). Considering all together the risk factors associated with mortality, at Cox regression multivariate analysis only moderate-severe CKD (OR 1.61, 95% CI 1.07–2.42, p 0.021), age of onset greater than 69 years (OR 2.01, 95% CI 1.37–2.95, p <0.001) and eGFR less than 92 ml/min (OR 2.84, 95% CI 1.51–5.34, p 0.001) were independently associated with risk of death. Conclusions Patients with DFU have high mortality and reduced life expectancy. Age at onset of diabetic foot ulcer, eGFR values and CKD are the principal risk factors for mortality.

Abstract
The diabetic foot (DF) is one of the most feared conditions among chronic complications of diabetes, which affects a growing number of patients. Although exercise therapy (ET) has always been considered a pillar in the treatment of patients at risk of DF it is not usually used. Several causes can contribute to hindering both the organization of ET protocols for Diabetes Units and the participation in ET programs for patients at different levels of risk of foot ulceration. The risk of favoring the occurrence of ulcers and the absence of clear evidence on the role played by ET in the prevention of ulcers could be considered among the most important causes leading to the low application of ET. The increased availability of new technologies and in particular of systems and devices equipped with sensors can enable the remote monitoring and management of physical activity performed by patients. Consequently, they can become an opportunity for introducing the systematic use of ET for the treatment of patients at risk. Considering the complexity of the clinical conditions that patients at risk or with diabetic foot ulcer can show, the evaluation of how patients perform the ET proposed can consequently be very important. All this can contribute to improving the treatment of patients and avoiding possible adverse effects. The aim of this brief review was to describe that the use of new technologies and the assessment of the execution of the ET proposed allows an important step forward in the management of patients at risk.

Abstract
Diabetic foot amputation is associated with high morbidity and mortality rates. To prevent cardiovascular complications along with vasculopathy in the course of diabetes mellitus, a high number of patients receive anticoagulant therapy. However, anticoagulants are contraindicated in neuraxial anesthesia limiting available anesthetic modalities. Therefore, in this retrospective study, we aimed to compare between general anesthesia and peripheral nerve block (PNB) with respect to postoperative complications following lower extremity amputation (LEA) in patients with coagulation abnormalities. In total, 320 adult patients who underwent LEA for diabetic foot were divided into two groups according to the anesthetic type (general anesthesia vs. PNB). The inverse probability of treatment weighting was performed to balance the baseline patient characteristics and surgical risk between the two groups. The adjusted analysis showed that compared with the general anesthesia group, the PNB group had lower risks of pneumonia (odds ratio: 0.091, 95% confidence interval [CI]: 0.010-0.850, p = 0.0355), acute kidney injury (odds ratio: 0.078, 95% CI: 0.007-0.871, p = 0.0382), and total major complications (odds ratio: 0.603, 95% CI: 0.400-0.910, p = 0.0161). Additionally, general anesthesia was associated with a higher amount of intraoperative crystalloid administration and a requirement for more frequent vasopressors. In conclusion, PNB appears to be protective against complications following LEA in diabetes patients with coagulopathy.

Abstract
OBJECTIVE To investigate the clinical effect of extracorporeal circulation compression perfusion (ECCP) in the treatment of diabetic foot. METHODS We retrospectively evaluated 89 patients with diabetic foot admitted from January 2017 to April 2019. The patients were grouped according to whether they received ECCP treatment; experimental group: 27 patients, controls: 62 patients. After applying the inclusion criteria and exclusion criteria, there were 21 patients in the experimental group and 21 patients in the control group. Foot microcirculation was evaluated by measuring the percutaneous oxygen partial pressure (TcPO2) and infrared thermography (IRT). Wound healing time and ulcer recurrence rate 1 year after discharge were compared between the groups. RESULTS TcPO2 and IRT values in the experimental group differed significantly compared with the control group. Foot ulcer healing time in the experimental group was shorter than that in the control group (17.10 ± 3.08 days vs 25.38 ± 4.40 days, respectively), and the recurrence rate after 1 year in the experimental group was lower than that in the control group (2/21, 9.5% vs 9/21, 42.8%, respectively). CONCLUSION ECCP improved foot microcirculatory perfusion in diabetic foot treatment. ECCP has clinical practicality and may accelerate wound healing speed and reduce ulcer recurrence.

Development and validation of an incidence risk prediction model for early foot ulcer in diabetes based on a high evidence systematic review and meta-analysis. Diabetes Res Clin Pract 2021; 180:109040. [PMID: 34500005 DOI: 10.1016/j.diabres.2021.109040] [Citation(s) in RCA: 17] [Impact Index Per Article: 5.7] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 07/16/2021] [Revised: 08/04/2021] [Accepted: 09/01/2021] [Indexed: 12/14/2022]
Abstract
OBJECTIVES To develop and validate a model for predicting the risk of early diabetic foot ulcer (DFU) based on systematic review and meta-analysis. METHODS Data were analyzed from the risk factors of DFU with their corresponding risk ratio (RR) by meta-analysis. The DFU prediction model included statistically significant risk factors from the meta-analysis, all of which were scored by its weightings, and the prediction model was externally validated using a validation cohort from China. The occurrence of early DFU was defined as patients with type 2 diabetes who were free of DFU at baseline and diagnosed with DFU at follow-up. Evaluation of model performance was based on the area under the discrimination receiver operating characteristic curve (ROC), with optimal cutoff point determined by calculation of sensitivity and specificity. Kaplan-Meier curve were performed tocompare the cumulative risk of different groups. RESULTS Our meta-analysis confirmed a cumulative incidence of approximately 6.0% in 46,521 patients with diabetes. The final risk prediction model included Sex, BMI, HbA1c, Smoker, DN, DR, DPN, Intermittent Claudication, Foot care, and their RRs were 1.87, 1.08, 1.21, 1.77, 2.97, 2.98, 2.76, 3.77, 0.38, respectively. The total score of all risk factors was 80 points according to their weightings. The prediction model showed good discrimination with AUC = 0.798 (95 %CI 0.738-0.858). At the optimal cut-off value of 46.5 points, the sensitivity, specificity and Youden index were 0.769, 0.798 and 0.567, respectively. The final model stratified the validation cohort into low, low-intermediate, high-intermediate and high-risk groups; Compared with low-risk group, the RR with 95 %CI of developing DFU in high-intermediate and high-risk group were 17.23 (5.12-58.02), p < 0.01 and 46.11 (5.16-91.74), p < 0.01, respectively. CONCLUSION We have developed a simple tool to facilitates early identification of patients with diabetes at high risk of developing DFU based on scores. This simple tool may improve clinical decision-making and potentially guide early intervention.

Abstract
Background: Diabetic Foot Ulcer (DFU) has been associated with a high mortality rate of Diabetes Mellitus (DM) patients. Both behavioral and biological factors cause predisposition to DFU. Purpose: This research describes the profile of hospitalized DFU patients at a tertiary care hospital in Surabaya. Methods: A retrospective descriptive study that analyzed medical records of hospitalized T2DM patients with DFU in Dr. Soetomo General Hospital. Sampled respondents were patients ≥ 21 years old who were hospitalized between 2016–2018. Demographic data, clinical characteristics, medical histories, length of hospital stay, laboratory results, precipitating factors, microorganism culture results, treatment, and outcome were analyzed. Descriptive analysis is presented in the form of narratives, tables, and diagrams. Results: 9.08% of hospitalized Type 2 DM (T2DM) cases were related to foot ulcers. The average patient age was 57.00 ± 9.83 years with no gender predominance. DM was poorly controlled (Mean HbA1C 9.78±2.83%; RBG 251.83 ± 158.15 mg/dL). The majority of patients had sepsis (68.26%) and renal function impairment (62.72%). Ulcers with Wagner grades of 4–5 were frequent (41.31%). The highest percentage of sepsis (80.49%) and the average leukocyte level (22.60±11.95 x109/L) were found in gangrenous feet. Anemia was more predominant and severe in ulcers with higher Wagner grades. Trauma and Escherichia coli were the most common precipitating factors and microorganisms isolated, respectively. Amputation was performed for 82.36% of patients who were admitted to hospital with gangrene. The Lower Extremity Amputation (LEA) and mortality rates were 14.11% and 40.93%, respectively. Conclusion: DFUs were found to have a relatively high prevalence among T2DM patients, and must never be neglected due to the high associated mortality rate.

Abstract
Diabetic foot ulcer (DFU) is a major debilitating complication of diabetes. Many research investigations have been conducted with the aims to uncover the diabetic wound healing mechanisms, develop novel therapeutics, and screen bioactive wound dressings in order to improve the current management of DFU. These would have not been possible without the utilization of an appropriate wound model, especially in a diabetic wound context. This review focuses on the different in vitro research models used in DFU investigations such as the 2D scratch wound assay, 3D skin model, and 3D angiogenesis model as well as their limitations. The current efforts and challenges to apply the 2D and 3D in vitro models in a hyperglycemic context to provide insights into DFU modeling will be reviewed. Perspectives of utilizing 3D bioprinting and skin-on-the-chip model as a diabetic wound model in the future will also be highlighted. By leveraging knowledge from past experiences and current research, an improved experimental model for DFU is anticipated to be established in near future.

Abstract
BACKGROUND AND PURPOSE Diabetic foot ulcers (DFUs) markedly contribute to morbidity and mortality of diabetic patients. Hence, this study was conducted to investigate the predictors of foot ulcers among Egyptian diabetic patients. METHODS A case-control study was conducted among 488 diabetic patients attending the inpatient departments and outpatient clinics at the National Diabetes Institute in Egypt. A pretested data collection sheet was designed to collect and record the following: socio-demographic data, diabetic history and lifestyle characteristics, recorded comorbidities, and the results of foot examination. RESULTS Significant positive predictors of DFUs on multivariate logistic regression analysis included presence of three or more comorbidities; two or more diabetic complications; callus; and flatfoot. Significant protective (negative) predictors were management of diabetes by diet, oral hypoglycemic drugs (OHGs), and insulin; and intact vibration sense. CONCLUSION Significant positive predictors of DFUs on multivariate analysis were presence of three or more comorbidities, two or more diabetic complications, callus and flatfoot, while protective predictors were management of diabetes by diet, OHGs, and insulin; and intact vibration sense. Hence, close monitoring should be provided to diabetic patients with comorbidities and complications to reduce the risk of DFUs.

Abstract
Aims To reduce diabetic foot complications, an annual screening of diabetes-related foot disease (DRFD) should be promoted. The screening tool as the Thai translated Questionnaire for Diabetes-related Foot Disease, Thai Q-DFD, has been established. The study was designed to assess the validity and reliability of the Thai Q-DFD before practical use in the community. Methods One hundred and thirty-nine persons with diabetes volunteered in a concurrent validity testing for agreement in diagnosis between the Thai Q-DFD and the standard clinical examinations. The test-retest reliability (a stability of a tool over time between three days apart) was assessed in 50 volunteers. The agreement in either validity or reliability test was evaluated using kappa coefficient. Results The screening diagnosis as DRFD by the Thai Q-DFD substantially agreed with that by the standard clinical examinations (kappa = 0.71). The Thai Q-DFD also showed high sensitivity (0.92) and specificity (0.78). Additionally, the Thai Q-DFD presented good test-retest reliability for DRFD diagnosis (kappa = 0.74). Conclusions The Thai Q-DFD is comparable to the original English version in terms of concurrent validity and test-retest reliability. Therefore, it can be used for a screening of DRFD in Thai people.

Abstract
The aim of this study is to investigate the risk factors of diabetic foot ulcer (DFU) in patients with Type 2 diabetes. Baseline characteristics of DFU-free patients with Type 2 diabetes were retrospectively collected and DFU was identified during the follow-up. Incidence of DFU was calculated and cumulative incidence was estimated by Kaplan-Meier method. Cox regression model was used to explore factors associated with DFU. A total of 980 patients were included with a median follow-up time of 28.7 months. 259 (26.4%) patients developed DFU with an incidence rate of 11.3 per 100 person-years. The cumulative incidences of DFU at 1 year and 2 years during the follow-up were 5.4% (95% CI 3.9-6.9%) and 14.1% (95% CI 11.7-16.5%), respectively. Cox regression analysis indicated that factors associated with developing DFU included age (hazard ratio (HR)=1.06, 95% CI 1.05-1.07, per 1-year increase), body mass index (HR=1.05, 95% CI 1.02-1.07), higher level of education (HR=0.77, 95% CI 0.60-0.98), hypertension (HR=1.90, 95% CI 1.47-2.45), hyperlipidemia (HR=2.63, 95% CI 2.02-3.43), coronary heart disease (HR=2.88, 95% CI 2.22-3.75), heart failure (HR=2.47, 95% CI 1.91-3.20), stroke (HR=2.44, 95% CI 1.86-3.19), diabetic retinopathy (HR=1.86, 95% CI 1.40-2.48), diabetic kidney disease (HR=1.89, 95% CI 1.41-2.53), diabetic neuropathy (HR=1.73, 95% CI 1.31-2.30), poor glycemic control (HR=1.13, 95% CI 1.07-1.19, per 1% glycosylated hemoglobin increase), and course of diabetes (HR=1.01, 95% CI 1.00-1.01, per 1-month increase). The results showed a relatively high incidence of DFU, and revealed several baseline characteristics identified as risk factors of developing DFU.

Abstract
AIMS To explore the factors related to hospital-to-home transitional self-monitoring blood glucose behaviour among patients with diabetes-related foot ulcer. BACKGROUND The 30-day readmission rate of patients with diabetes-related foot ulcer can be reduced when good glycaemic control is achieved. The practice of self-monitoring blood glucose promotes optimal glycaemic control. DESIGN A comparative descriptive study. METHODS In this study, 200 participants, who had been hospitalized due to diabetes-related foot ulcer, were recruited from August 2017 to July 2018. Before participants were discharged from the hospital, psychosocial factors (family support, threat belief, self-efficacy and knowledge) and pre-hospitalization self-monitoring blood glucose behaviour were collected using a structured questionnaire. Then, after discharge, self-monitoring blood glucose behaviour delivery was collected again. RESULTS Five variables explained 47% of the variance in the delivery of self-monitoring of blood glucose at home. The delivery of hospital-to-home transitional self-monitoring blood glucose behaviour was more likely for individuals with higher pre-discharge self-efficacy, higher post-discharge self-efficacy, more attention to pre-hospitalization glycaemic status and post-discharge insulin usage and those without an insensitive foot. CONCLUSION Self-monitoring blood-glucose behaviour should be promoted among post-discharge patients with diabetes-related foot ulcer. The modifiable factors identified in this study can be integrated into the discharge plan.

Effects of Custom-Made Insole Materials on Frictional Stress and Contact Pressure in Diabetic Foot with Neuropathy: Results from a Finite Element Analysis. APPLIED SCIENCES-BASEL 2021.

Abstract
Offloading plantar pressure in a diabetic foot with neuropathy is challenging in conventional clinical practice. Custom-made insole (CMI) materials play an important role in plantar pressure reduction, but the assessment is costly and time-consuming. Finite element analysis (FEA) can provide an efficient evaluation of different insoles on the plantar pressure distribution. This study investigated the effect of CMI materials and their combinations on plantar pressure reduction for the diabetic foot with neuropathy using FEA. The study was conducted by constructing a three-dimensional foot model along with CMI to study the peak contact pressure between the foot and CMI. The softer material (E = 5 MPa) resulted in a better reduction of peak contact pressure compared with the stiffer material (E = 11 MPa). The plantar pressure was well redistributed with softer material compared with the stiffer material and its combination. In addition, the single softer material resulted in reduced frictional stress under the first metatarsal head compared with the stiffer material and the combination of materials. The softer material and its combination have a beneficial effect on plantar pressure reduction and redistribution for a diabetic foot with neuropathy. This study provided an effective approach for CMI material selection using FEA.
