COX-2 targeted therapy for diabetic foot ulcers using T7-enhanced CS-PVA membranes. Int Immunopharmacol 2024; 143:113206. [PMID: 39353389 DOI: 10.1016/j.intimp.2024.113206] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/27/2024] [Revised: 08/30/2024] [Accepted: 09/17/2024] [Indexed: 10/04/2024]
Abstract
Diabetic foot ulcers can lead to severe complications, including infection, gangrene, and even amputation, significantly impacting patients' quality of life. The application of anti-inflammatory compounds loaded into chitosan membranes offers targeted therapeutic effects, reducing inflammation and promoting tissue regeneration. This study evaluates the therapeutic efficacy of T7, a selective COX-2 inhibitor, incorporated into chitosan-polyvinylalcohol (CS-PVA) membranes for diabetic wound treatment. Cytotoxicity analysis showed high cell viability across various T7 concentrations, indicating minimal cytotoxicity. In silico pharmacology identified 98 potential inflammation-related targets for T7, further supported by GO and KEGG enrichment analyses. Developmental toxicity tests on zebrafish embryos indicated no significant toxicity up to 100 µM concentration. SEM and FTIR analyses confirmed the successful incorporation of T7 into the CS-PVA membrane, while XRD analysis indicated structural stability. The drug release assay demonstrated a sustained release profile, crucial for prolonged therapeutic efficacy. Antibacterial activity assays revealed significant inhibition of common pathogens. In vivo wound healing assays showed accelerated wound closure and enhanced collagen deposition, with histological and immunohistochemistry analyses supporting improved tissue architecture and reduced inflammation. Gene expression analysis confirmed reduced inflammatory markers. These findings suggest that T7-loaded CS-PVA membranes offer a promising, multifaceted approach to diabetic wound treatment, combining anti-inflammatory, antimicrobial, and collagen-promoting properties for effective wound healing.

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

J Tissue Viability 2024:S0965-206X(24)00108-6. [PMID: 39004600 DOI: 10.1016/j.jtv.2024.07.002] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/17/2024] [Revised: 06/15/2024] [Accepted: 07/09/2024] [Indexed: 07/16/2024]
Abstract
BACKGROUND Diabetic foot ulcer is one of the most prevalent, serious, and costly consequences of diabetes, often associated with peripheral neuropathy and peripheral arterial disease. These ulcers contribute to high disability and mortality rates in patients and pose a major challenge to clinical management. OBJECTIVE To systematically review the risk prediction models for post-healing recurrence in diabetic foot ulcer (DFU) patients, so as to provide a reference for clinical staff to choose appropriate prediction models. METHODS The authors searched five databases (Cochrane Library, PubMed, Web of Science, EMBASE, and Chinese Biomedical Database) from their inception to September 23, 2023, for relevant literature. After data extraction, the quality of the literature was evaluated using the Predictive Model Research Bias Risk and Suitability Assessment tool (PROBAST). Meta-analysis was performed using STATA 17.0 software. RESULTS A total of 9 studies involving 5956 patients were included. The recurrence rate after DFU healing ranged from 6.2 % to 41.4 %. Nine studies established 15 risk prediction models, and the area under the curve (AUC) ranged from 0.660 to 0.940, of which 12 models had an AUC≥0.7, indicating good prediction performance. The combined AUC value of the 9 validation models was 0.83 (95 % confidence interval: 0.79-0.88). Hosmer-Lemeshow test was performed for 10 models, external validation for 5 models, and internal validation for 6 models. Meta-analysis showed that 14 predictors, such as age and living alone, could predict post-healing recurrence in DFU patients (p < 0.05). CONCLUSION To enhance the quality of these risk prediction models, there is potential for future improvements in terms of follow-up duration, model calibration, and validation processes.

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

Abstract
Diabetic foot ulcers are a common and severe complication of diabetes mellitus, and a risk factor for amputation. Because of the vessel insufficiency in diabetic foot ulcers (DFU), vascular endothelial growth factor (VEGF) that simulates angiogenesis is of interest to promote wound healing. This systematic review evaluates the last 16 years of in-vivo studies with VEGF stimulation as a treatment for DFU, developed based on the last published systematic article. A total of 961 articles were identified through databases in two phases. 947 articles were excluded by exclusion criteria, and four articles met our inclusion criteria and were included. The effects of VEGF on wound healing were analysed in all four studies. In three studies, the VEGF-treated wounds showed statistically faster healing than those not treated with VEGF. In one study, the VEGF-treated wounds revealed a positive trend toward faster healing. Furthermore, all four studies were in favor of using VEGF, but concluded that further research is needed. These studies showed a positive trend towards faster healing and was safe when using VEGF topically on humans. Furthermore, viral particles of VEGF seem to have a systematic effect when a dose exceeding 5.0 × 109 vp pr wound. Future research in using VEGF on DFU should focus on VEGF's relevant dosage, release rate, and specific mechanism. This review inspires further research, and a consistent study design is prerequisite such that results are more homogenic and comparable. Much effort is needed to translate the results into our clinical practice.

Abstract
Diabetic foot ulcers were a significant complication of diabetes and were accompanied by delayed wound healing. To compare the effect of topical application electrospun poly (L-lactide-co-caprolactone) and formulated porcine fibrinogen (PLCL/Fg) dressing with alginate dressing when treating diabetic foot ulcers (DFUs). A single-center, prospective, randomized, patient-blinded clinical trial was conducted from July 1, 2023, to December 26, 2023. The clinical trial registration was completed on August 28, 2023 (ClinicalTrials.gov Identifier: NCT06014437). The eligible patients with DFUs of 1-20 cm2 present for at least 1 month and with Wagner grade 1 or 2. They were randomized 1:1 to receive PLCL/Fg or alginate dressing. Participants received PLCL/Fg dressing 1-3 times per week or alginate dressing 3 times per week for 12 weeks. A total of 52 patients (33 men [63.5 %]; mean [SD] age, 63.1 [11.9] years; mean [SD] diabetes time, 8.3 [4.6] years) with DFUs were assessed for this study. The DFUs classified as Wagner grade 1 or 2 (mean [SD] ulcer area, 3.8 [3.2] cm2) were randomized to receive either the PLCL/Fg dressing (n = 26) or the alginate dressing (n = 26) for as long as 12 weeks. In this study, the incidence of complete healing included 22 patients (91.7 %) in the PLCL/Fg group and 14 (63.6 %) in the alginate group during the 12-week treatment period (P = 0.003). The treatment-related adverse events that occurred were 5 (20.8 %) in the PLCL/Fg group and 4 (18.1 %) in the comparator group. In this randomized clinical trial, PLCL/Fg dressing showed beneficial effects in DFUs treatment of wound surface reduction and regulating the wound microenvironment.

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%).

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

Bioengineered MSC Cxcr2 transdifferentiated keratinocyte-like cell-derived organoid potentiates skin regeneration through ERK1/2 and STAT3 signaling in diabetic wound. Cell Mol Life Sci 2024; 81:172. [PMID: 38597972 PMCID: PMC11006766 DOI: 10.1007/s00018-023-05057-3] [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: 06/22/2023] [Revised: 11/17/2023] [Accepted: 11/18/2023] [Indexed: 04/11/2024]
Abstract
Skin regeneration is severely compromised in diabetic foot ulcers. Allogeneic mesenchymal stem cell (MSC) transplantation is limited due to the poor engraftment, mitogenic, and differentiation potential in the harsh wound microenvironment. Thus, to improve the efficacy of cell therapy, the chemokine receptor Cxcr2 was overexpressed in MSCs (MSCCxcr2). CXCL2/CXCR2 axis induction led to the enhanced proliferation of MSCs through the activation of STAT3 and ERK1/2 signaling. Transcriptional upregulation of FGFR2IIIb (KGF Receptor) promoter by the activated STAT3 and ERK1/2 suggested trans-differentiation of MSCs into keratinocytes. These stable MSCCxcr2 in 2D and 3D (spheroid) cell cultures efficiently transdifferentiated into keratinocyte-like cells (KLCs). An in vivo therapeutic potential of MSCCxcr2 transplantation and its keratinocyte-specific cell fate was observed by accelerated skin tissue regeneration in an excisional splinting wound healing murine model of streptozotocin-induced type 1 diabetes. Finally, 3D skin organoids generated using MSCCxcr2-derived KLCs upon grafting in a relatively avascular and non-healing wounds of type 2 diabetic db/db transgenic old mice resulted in a significant enhancement in the rate of wound closure by increased epithelialization (epidermal layer) and endothelialization (dermal layer). Our findings emphasize the therapeutic role of the CXCL2/CXCR2 axis in inducing trans-differentiation of the MSCs toward KLCs through the activation of ERK1/2 and STAT3 signaling and enhanced skin regeneration potential of 3D organoids grafting in chronic diabetic wounds.

Int Wound J 2024; 21:e14586. [PMID: 38102851 PMCID: PMC10961876 DOI: 10.1111/iwj.14586] [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: 10/26/2023] [Revised: 12/05/2023] [Accepted: 12/06/2023] [Indexed: 12/17/2023] Open
Abstract
This study aimed to explore the association between metabolic-associated fatty liver disease (MAFLD) and ulcer recurrence risk in patients with diabetic foot ulcers (DFUs) through an ambispective longitudinal cohort. From December 2013 to December 2022, a total of 482 inpatients with DFUs (PEDIS grade 3 and above with a severe infection) were eligible for inclusion in this study. This was an ambispective longitudinal cohort study. All participants were followed up every 6 months for 9 years with a median of 36 months. According to whether having MAFLD or not, all subjects were placed into two groups: non-MAFLD (n = 351) and MAFLD (n = 131). The association between MAFLD and ulcer recurrence in patients with DFUs was then evaluated through multivariate Cox regression analysis, stratified analyses and Kaplan-Meier survival analysis. Throughout the follow-up period, out of 482 subjects with DFUs, 68 had ulcer recurrence (14.1%). Three Cox regression models were established for data analyses. In the model I (unadjusted), MAFLD was significantly associated with the ulcer recurrence rate in patients with DFUs (HR = 1.79; 95% CI = 1.097-2.92; p = 0.02). Model II (adjusted model I with gender and age) (HR = 1.781; 95% CI = 1.09-2.912; p = 0.021) and model III (adjusted model II with CVD, duration of diabetes and Cr.) (HR = 1.743; 95% CI = 1.065-2.855; p = 0.027) also showed that MAFLD was significantly related to the ulcer recurrence risk in patients with DFUs, respectively. Stratified analysis indicated that subjects aged ≥60 had a greater risk of ulcer recurrence in MAFLD than in non-MAFLD (HR = 2.31; 95% CI = 1.268-4.206; p = 0.006). Kaplan-Meier survival curve analysis showed that ulcer recurrence rate had a significant association with MAFLD (log-rank, p = 0.018). This study indicated a close association between ulcer recurrence risk and MAFLD in patients with DFUs, especially in the elderly (aged ≥60). Therefore, special attention should be paid to the elderly with both DFUs and MAFLD because they have a higher ulcer recurrence rate than other general populations in routine clinical practice.

Abstract
Diabetic foot ulcers (DFUs) pose a significant clinical challenge, often leading to amputations and hospitalisation. This study aimed to investigate the characteristics and outcomes of DFUs treated with surgical debridement and standardised wound care. This descriptive cross-sectional study focused on diabetic patients with appropriate vascular conditions, as determined by an Ankle Brachial Index >0.9. Based on their infection status, participants were admitted to Poursina Hospital in Rasht, Iran, and subjected to initial supportive measures, antibiotic therapy and surgical debridement. The study incorporated primary treatment with wet bandages, silver spray and fibrinolysin ointment. Statistical analysis employed SPSS 22 software. Most patients were male (54.7%) and under 60 years old (50.7%). Overweight status was prevalent in 69.3% of diabetic ulcer patients, amongst whom 48% underwent wrist debridement. The 64% and 36% of the cases had grade III and grade II Texas index. Moreover, 96% of patients exhibited signs of infection and were classified as Stage Texas B. Reoperation was necessary for 34.7% of patients. The mean hospital stay was 8.5 ± 7.55 days, and the average recovery time was 15.2 ± 15.19 days. Out of 75 patients, 10 were unable to return to limb function due to disability. In this study, around one-third of patients required secondary repair with grafts and flaps. A small number of them were unable to recover because of underlying disability, and the mean recovery time in other cases was 24 days. Future studies should follow up with patients for longer periods to assess long-term therapeutic outcomes and quality of life.

Abstract
Complications associated with Type 1 and Type 2 diabetes, such as diabetic peripheral neuropathy and diabetic foot ulcers, are a growing health-care concern. In addition, this concern increases as diabetic patients age due to their increased susceptibility to complications. To address this growing problem, it is important to understand fluctuations in physiology which lead to pathological changes associated with the metabolic disturbances of diabetes. Our study explores dysregulation of immune cell populations in the hindpaws of healthy and diabetic mice at 12 and 21 weeks of age using single-cell RNA sequencing to provide insight into immune disruptions occurring in the distal limb during chronic diabetes. In 21-week-old Leprdb/db mice, increases were seen in mast cells/basophils, dermal γδ T cells, heterogeneous T cells, and Type 2 innate lymphoid cells. In addition, macrophages represented the largest cluster of immune cells and showed the greatest increase in genes associated with immune-specific pathways. Sub-clustering of macrophages revealed a bias toward angiogenic Lyve1+MHCIIlo macrophages in the hindpaws of 21-week-old diabetic mice, which corresponded to an increase in Lyve1+ macrophages in the hindpaws of 21-week-old diabetic mice on histology. Our results show that in Type 2 diabetes, the immunological function and phenotype of multiple immune cell types shift not only with metabolic disturbance, but also with duration of disease, which may explain the increased susceptibility to pathologies of the distal limb in patients with more chronic diabetes.

Abstract
INTRODUCTION Diabetic foot ulcer (DFU) is a disabling complication of diabetes mellitus. Here, we attempted to assess whether long-term intrafemoral artery infusion of low-dose urokinase therapy improved DFUs and decreased cardiovascular events in patients with DFUs. RESEARCH DESIGN AND METHODS This trial was a single-center, randomized, parallel study. A total of 195 patients with DFU were randomized to continuous intrafemoral thrombolysis or conventional therapy groups. The continuous intrafemoral thrombolysis group received continuous intrafemoral urokinase injection for 7 days, and conventional therapy just received wound debridement and dressing change. Then, a follow-up of average 6.5 years was performed. RESULTS Compared with conventional therapy, at the first 1 month of intervention stage, the ulcers achieved a significant improvement in continuous intrafemoral thrombolysis group including a complete closure (72.4% vs 17.5%), an improved ulcer (27.6% vs 25.8%), unchanged or impaired ulcer (0% vs 56.7%). During the 6.5-year follow-up, for the primary outcome of ulcer closure rate, continuous intrafemoral thrombolysis therapy obtained a better complete healing rate (HR 3.42 (95% CI 2.35 to 4.98, p<0.0001)). For the secondary outcome of cardiovascular disease events, continuous intrafemoral thrombolysis therapy had a lower incidence of cardiovascular events (HR 0.50 (95% CI 0.34 to 0.74, p<0.0001)). Importantly, intrafemoral thrombolysis therapy decreased the incidence of cardiovascular death (HR 0.42 (95%CI 0.20 to 0.89, p=0.0241)). Additionally, continuous intrafemoral thrombolysis therapy improved local skin oxygenation and peripheral neuropathy as well as glycolipid metabolic profiles when compared with conventional therapy group (p<0.05). CONCLUSIONS Continuous intrafemoral thrombolysis therapy has a better therapeutic efficacy to improve DFUs and decrease cardiovascular events. TRIAL REGISTRATION NUMBER NCT01108120.

Abstract
This analysis systematically reviewed the efficacy of evidence-based care on diabetic foot ulcers. A computerised literature search was conducted for randomised controlled studies (RCTs) of evidence-based care interventions for the treatment of diabetic foot ulcers using the PubMed, Embase, Cochrane Library, Web of Science, China National Knowledge Infrastructure (CNKI), China Biomedical Literature Database (CBM) and Wanfang databases from the date of inception of each database to June 2023. The articles were independently screened, data were extracted by two researchers, and the quality of each study was assessed using the Cochrane bias assessment tool. Meta-analysis of the data was performed using RevMan 5.4 software. Twenty-five RCTs with a total of 2272 patients were included. Meta-analysis showed that, compared with other care methods, evidence-based care significantly improved the treatment efficacy of diabetic foot ulcers (odds ratio: 3.91, 95% confidence interval [CI]: 2.76 to 5.53, p < 0.001) and significantly reduced their fasting plasma glucose (mean difference [MD]: -1.10, 95% CI: -1.24 to -0.96, p < 0.001), 2-h postprandial glucose (2hPG) (MD: -1.69, 95% CI: -2.07 to -1.31, p < 0.001) and glycated haemoglobin (HbA1c) (MD: -0.71, 95% CI: -0.94 to -0.48, p < 0.001). Evidence-based care intervention is effective at reducing FPG, 2hPG and HbA1c levels and improving treatment efficacy in patients with diabetic foot ulcers.

Abstract
Background Diabetic foot ulcers (DFUs) are one of the most common and fatal complications of diabetic patients with uncontrolled diabetes mellitus (DM) that may end with their feet amputation. These complications can be prevented through the adherence of diabetic patients to their diabetes management plan and by educating them about risk factors, complications of diabetic foot, and proper foot care. To develop effective health education programs to educate diabetic patients and caregivers regarding diabetic foot and its effective care, we should first identify gaps in patients' knowledge and perception of diabetic foot and evaluate their practice of foot care. Objectives This study aimed to evaluate knowledge and attitude toward DFUs and the practice of foot care among adult diabetic patients attending Al-Qunfudah Diabetes Center, Saudi Arabia, from October 2022 to March 2023. Methods A total of 403 adult diabetic patients were recruited in this cross-sectional study during their attendance at the diabetes center in Al-Qunfudah district, Saudi Arabia. The study researchers conducted a physical face-to-face interview with each diabetic patient using a validated questionnaire with closed-ended questions to collect their responses regarding their knowledge and attitude toward DFUs and their behavior toward foot care. The collected data were analyzed using IBM SPSS Statistics for Windows, version 23 (released 2015; IBM Corp., Armonk, New York, United States). Results Out of 403 diabetics, 50.4% (n = 203) had inadequate knowledge (knowledge score < 80%), 46.4% (n = 187) had negative attitudes (attitude score < 80%) toward DFUs, and the majority could not practice foot care well, with 77.7% (n = 313) giving a practice score less than 80%. Seventy patients (17.4%) self-reported a history of DFUs. Predictors of good knowledge about DFUs among diabetics include age between 30 and 59 years (odds ratio (OR) = 2.942, confidence interval (CI) 95% = 1.695-2.107, p < 0.001), marriage (OR = 3.101, CI 95% = 1.893-5.079, p < 0.001), working (OR = 5.325, CI 95% = 3.019-9.389, p < 0.001), diploma education (OR = 8.205, CI 95% = 3.332-20.203, p < 0.001), managing DM with oral drugs (OR = 2.219, CI 95% = 1.399-3.519, p < 0.001), and having no DFUs (OR = 2.712, CI 95% = 1.557-4.723, p < 0.001). Males were more likely to practice foot care well (OR = 1.925, CI 95% = 1.142-3.245, p = 0.013). Primary education (OR = 3.421, CI 95% = 1.655-7.073, p < 0.001) predicted appropriate foot care. Patients with DM for one to five years (OR = 1.995, CI 95% = 1.139-3.493, p = 0.016) and those on diet and metformin (OR = 2.133, CI 95% = 1.134-4.011, p = 0.019) were expected to have better foot care than other diabetics. Conclusion Diabetic patients in the Al-Qunfudah district of Saudi Arabia had inadequate knowledge and negative attitudes toward DFUs, and their foot care behaviors were inadequate. Furthermore, DFUs were self-reported in around 17% of diabetic patients. Specialized training programs are recommended to enhance knowledge regarding DFUs among diabetics and motivate and train them and caregivers on how to conduct proper foot care. These educational programs should target all diabetics, with an emphasis on those with DFUs, females, non-working patients, individuals who have had DM for a longer time, and illiterate diabetics. To understand the factors behind patients' negative attitudes toward diabetic foot, future qualitative research is required.

Abstract
Ozonated oil increases the healing of chronic diabetic wounds, but the underlying mechanisms remain unclear. We investigated the effect of topical ozonated oil on wound healing in mice with diabetes with diet-induced obesity and further elucidated the role of EGFR and IGF1R signaling in diabetic wound healing. We found that topical ozonated oil accelerated wound healing; increased phosphorylation of IGF1R, EGFR, and VEGFR; and improved vascularization at the wound leading edge in mice with diabetes with diet-induced obesity. Exposure of normal epidermal keratinocytes to ozonated medium (20 μM for 2 hours daily) increased cell proliferation and migration distance by increasing phosphorylation of IGF1R and EGFR and downstream phosphoinositide 3-kinase, protein kinase B, and extracellular signal-regulated kinase. These findings shed light on the mechanism for topical ozone action in chronic wounds and support its potential therapeutic application.

Identification of contributing factors, microorganisms and antimicrobial resistance involved in the complication of diabetic foot ulcer treatment. Microb Pathog 2023; 184:106363. [PMID: 37730169 DOI: 10.1016/j.micpath.2023.106363] [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] [Revised: 09/04/2023] [Accepted: 09/15/2023] [Indexed: 09/22/2023]
Abstract
Diabetic foot ulcer (DFU) is a neurological and peripherical complication of diabetes with unknown etiology that is often associated with polymicrobial infections. The present study was conducted to investigate the contributing factors in 285 DFU patients, which included 200 patients with diabetic foot infections (DFI). Identification and characterization of infecting bacterial isolates were done followed by assessment of their pattern of susceptibility to commonly used antibiotics. Among the studied subjects, type 2 diabetes mellitus (T2DM), ulcer type, depth, grade, loss of sensation, infection type, affected foot, recurrence, smoking status, Body Mass Index (BMI), and obesity levels revealed significant disease risk association. Ulcer grades 1 and 2 were more common in males while grade 3 in females. Recurrent infections were significantly higher in females (P = 0.03). Diabetic duration, hyperglycemia, ulcer type, infection type and BMI were positively correlated with delayed wound healing. In DFI samples, 40.2% consisted of gram-negative bacteria, with Pseudomonas aeruginosa (37.5%) being the most common, while in the 60% gram-positive isolates Staphylococcus aureus (40.5%) was the predominant species. Staphylococcus epidermidis was found more frequently in females (P = 0.05). The isolated bacterial strains presented higher resistance against the tested antibiotics; however, ceftriaxone was effective against most of the pathogens. In the current study T2DM along with diabetes duration, obesity, ulcer severity with polymicrobial infection was found to play a strong role in DFI development, where gender predisposition was also observed in ulcer grade and infection. DFI was correlated with loss of sensation, infection type, affected foot, smoking status, BMI and obesity levels.

BMJ Open Diabetes Res Care 2023; 11:e003523.

Abstract
INTRODUCTION Diabetic foot ulcer (DFU) stands as a severe diabetic lower extremity complication, characterized by high amputation rates, mortality, and economic burden. We propose using Mendelian randomization studies to explore shared and distinct risk factors for diabetic lower extremity complications. RESEARCH DESIGN AND METHODS We selected uncorrelated genetic variants associated with 85 phenotypes in five categories at the genome-wide significance level as instrumental variables. Genetic associations with DFU, diabetic polyneuropathy (DPN), and diabetic peripheral artery disease (DPAD) were obtained from the FinnGen and UK Biobank studies. RESULTS Body mass index (BMI) emerged as the only significant risk factor for DPAD, DPN, and DFU, independent of type 2 diabetes, fasting glucose, fasting insulin, and HbA1c. Educational attainment stood out as the sole significant protective factor against DPAD, DPN, and DFU. Glycemic traits below the type 2 diabetes diagnosis threshold showed associations with DPAD and DPN. While smoking history exhibited suggestive associations with DFU, indicators of poor nutrition, particularly total protein, mean corpuscular hemoglobin, and mean corpuscular volume, may also signal potential DFU occurrence. CONCLUSIONS Enhanced glycemic control and foot care are essential for the diabetic population with high BMI, limited education, smoking history, and indicators of poor nutrition. By focusing on these specific risk factors, healthcare interventions can be better tailored to prevent and manage DFU effectively.

Abstract
Our paper proposes the first machine learning model to predict long-term mortality in patients with diabetic foot ulcers (DFUs). The study includes 635 patients with DFUs admitted from January 2007 to December 2017, with a follow-up period extending until December 2020. Two multilayer perceptron (MLP) classifiers were developed. The first MLP model was developed to predict whether the patient will die in the next 5 years after the current hospitalization. The second MLP classifier was built to estimate whether the patient will die in the following 10 years. The 5-year and 10-year mortality models were based on the following predictors: age; the University of Texas Staging System for Diabetic Foot Ulcers score; the Wagner-Meggitt classification; the Saint Elian Wound Score System; glomerular filtration rate; topographic aspects and the depth of the lesion; and the presence of foot ischemia, cardiovascular disease, diabetic nephropathy, and hypertension. The accuracy for the 5-year and 10-year models was 0.7717 and 0.7598, respectively (for the training set) and 0.7244 and 0.7087, respectively (for the test set). Our findings indicate that it is possible to predict with good accuracy the risk of death in patients with DFUs using non-invasive and low-cost predictors.

Abstract
INTRODUCTION Type 2 diabetes mellitus (T2DM) is a major public health problem. Foot-related complications are common in diabetic patients. The aim of this study is to identify predictive factors for lower limb amputation (LLA) in order to better identify this at-risk population. METHODS This was a cross-sectional study involving 134 patients who were hospitalised for the management of T2DM complicated by diabetic foot, in the department of endocrinology and diabetology. We included patients with T2DM whose diabetes was diagnosed 10 years ago or more, and who had a diabetic foot problem. Statistical differences between predictors of amputations were tested using: t-tests for numerical variables and chi-square tests for categorical variables. Significant variables were analysed by logistic regression to determine significant predictors. RESULTS The mean duration of diabetes was 17±7 years. We found that 70% of patients with LLA were older than 50 years (p<10-3). The prevalence of LLA was higher (p=0.015) in patients with diabetes for more than 20 years. We noted that 58% of patients who underwent LLA were hypertensive (p<10-3). The majority of patients with LLA (58%) had abnormal micro-albuminuria (p<10-3). We found that 70% (n=12) of patients with LLA had low-density protein cholesterol levels above the target value (p<10-3). Diabetic foot grade ≥4 (4 or 5) according to Wagner's classification, was present in 24% of amputee patients. Based on a 95% confidence interval level, the independent significant predictive factors for LLA in our patients were: T2DM for more than 20 years, hypertension and diabetic foot grade ≥4. CONCLUSIONS After multivariate analysis, the significant independent predictive factors associated with LLA were: T2DM for more than 20 years, hypertension, and diabetic foot grade ≥4. Early management of diabetic foot problems is therefore recommended to avoid amputations.

Abstract
Diabetic foot syndrome (DFS) is a complication associated with diabetes that has a strong negative impact, both medically and socio-economically. Recent epidemiological data show that one in six patients with diabetes will develop an ulcer in their lifetime. Vascular complications associated with diabetic foot have multiple prognostic implications in addition to limiting functional status and leading to decreased quality of life for these patients. We searched the electronic databases of PubMed, MEDLINE and EMBASE for studies that evaluated the role of DFS as a cardiovascular risk factor through the pathophysiological mechanisms involved, in particular the inflammatory ones and the associated metabolic changes. In the era of evidence-based medicine, the management of these cases in multidisciplinary teams of “cardio-diabetologists” prevents the occurrence of long-term disabling complications and has prognostic value for cardiovascular morbidity and mortality among diabetic patients. Identifying artificial-intelligence-based cardiovascular risk prediction models or conducting extensive clinical trials on gene therapy or potential therapeutic targets promoted by in vitro studies represent future research directions with a modulating role on the risk of morbidity and mortality in patients with DFS.

Abstract
BACKGROUND The chances of nonhealing foot ulcer among the diabetic is 10-20 times more than people without diabetes. Foot ulcer among diabetes population affects more than 40-60 million globally. There is a dearth of quality data on the factor among the diabetes patients, which hastens the progression of diabetic foot. The study aims to assess the risk factors associated with foot ulcer among the diabetics. MATERIALS AND METHODS The study was a cross-sectional comparative study in tertiary care hospital in Maharashtra, India. The study population included 200 diabetic foot ulcer patients and 200 of their age and gender matched comparator were patients with diabetes without foot ulcers. The sampling method was stratified random sampling. RESULTS The mean age of both the groups of patients was around 54 years. Alcohol consumption, physical activity outside home, low foot care practices, irregularity of diabetic medication, and family history of diabetes among mothers were found to be factors associated with diabetes foot ulcer. CONCLUSION There is a need to stratify the diabetes patients in regular care as per risk categories depending on the presence of above risk factors. This will not only prioritization of diabetes care in terms of future risk but also reduce the progression of complications like diabetes foot and resulting amputation through an active preventive intervention.

Abstract
BACKGROUND Diabetic foot ulcer (DFU) is a devastating complication of diabetes mellitus (DM) that is associated with increased mortality, morbidity, amputation rate and economic burden. This study aimed at identifying the anatomical distribution and factors associated with severity of DFU in Uganda. METHODOLOGY This was a multicenter cross-sectional study conducted in seven selected referral hospitals in Uganda. A total of 117 patients with DFU were enrolled in this study between November 2021 and January 2022. Descriptive analysis and modified Poisson regression analysis were performed at 95% confidence interval; factors with p-value < 0.2 at bivariate analysis were considered for multivariate analysis. RESULTS The right foot was affected in 47.9% (n = 56) of patients, 44.4% (n = 52) had the DFU on the plantar region of the foot and 47.9% (n = 56) had an ulcer of > 5 cm in diameter. The majority (50.4%, n = 59) of patients had one ulcer. 59.8% (n = 69) had severe DFU, 61.5% (n = 72) were female and 76.9% had uncontrolled blood sugar. The mean age in years was 57.5 (standard deviation 15.2 years). Primary (p = 0.011) and secondary (p < 0.001) school educational levels, moderate (p = 0.003) and severe visual loss (p = 0.011), 2 ulcers on one foot (p = 0.011), and eating vegetables regularly were protective against developing severe DFU (p = 0.03). Severity of DFU was 3.4 and 2.7 times more prevalent in patients with mild and moderate neuropathies (p < 0.01), respectively. Also, severity was 1.5 and 2.5 higher in patients with DFU of 5-10 cm (p = 0.047) and in those with > 10 cm diameter (p = 0.002), respectively. CONCLUSION Most DFU were located on the right foot and on the plantar region of the foot. The anatomical location was not associated with DFU severity. Neuropathies and ulcers of > 5 cm diameter were associated with severe DFU but primary and secondary school education level and eating vegetables were protective. Early management of the precipitating factors is important to reduce the burden of DFU.

Study on the regulatory effect of Panax notoginseng saponins combined with bone mesenchymal stem cell transplantation on IRAK1/TRAF6-NF-κB pathway in patients with diabetic cutaneous ulcers. J Orthop Surg Res 2023; 18:80. [PMID: 36721171 PMCID: PMC9890888 DOI: 10.1186/s13018-022-03467-w] [Citation(s) in RCA: 1] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 09/24/2022] [Accepted: 12/21/2022] [Indexed: 02/02/2023] Open
Abstract
Panax notoginseng saponins (PNSs) have been found as the major active ingredient of Panax notoginseng (Burkill) F.H.Chen (PN) leaves, which has the effect of reducing inflammatory response, facilitating fibroblast proliferation, as well as promoting angiogenesis. This study aimed to investigate the molecular basis of PNS combined with bone mesenchymal stem cells (BMSCs) for treating diabetic cutaneous ulcers (DCU) and its mechanism of action. METHODS A total of 75 SD rats were selected to make diabetic cutaneous ulcers model. According random number table method, the rats were randomly divided into a control group, a DCU group, a BMSCs group, a PNS group and BMSCs + PNS group. Five groups of rats were given without treatment. After being treated for 7 days, the rats were anesthetized with pentobarbital, and granulation tissue was collected from the central point of the wound. They were used for pathological analysis, Western blot (WB) and polymerase chain reaction (PCR) assays. RESULTS The wound healing area was the largest in the BMSCs + PNS group. HE staining results showed that the PNS + BMSCs group could promote the formation of new epidermis and reduce the infiltration of inflammatory cells. Immunohistochemistry (IHC) results showed that the PNS + BMSCs group could up-regulate the expression of Ki67 protein and cell proliferation. In addition, PNS combined with BMSCs up-regulated the expression of miR-146-5p and down-regulated the expression of IL-1β, IL-6 and TNF-α, IRAK1, TRAF6 and p65 in the NF-κB signaling pathway (p < 0.05). CONCLUSIONS PNS combined with bone mesenchymal stem cell transplantation up-regulated miR-146a-5p targeting and binding to IRAK1/TRAF6, inhibiting the activation of NF-κB pathway, which reduced the inflammatory response of DCU and facilitated the skin healing of DCU. Thus, this study provides a theoretical basis and a novel therapeutic option for the treatment of DFU with PNS combined with BMSCs.

Abstract
IMPORTANCE Diabetic foot ulcers (DFUs) and subsequent amputation incur enormous health and economic burdens to patients, health care systems, and societies. As a novel macrophage-regulating drug, ON101 is a breakthrough treatment for DFUs, which demonstrated significant complete wound healing effects in a phase 3 randomized clinical trial, but its economic value remains unknown. OBJECTIVE To assess the cost-effectiveness of an ON101 cream added on to general wound care (GWC; ie, conventional treatments for DFUs, which comprised initial and regular foot examinations, ulcer management, comorbidity control, patient education, and multidisciplinary care) vs GWC alone for DFUs from the Taiwan health care sector perspective. DESIGN, SETTING, AND PARTICIPANTS This economic evaluation used a hypothetical cohort of patients with diabetes, with characteristics mirroring those of the participants in the ON101 trial. A Markov state-transition simulation model was constructed to estimate costs and health outcomes associated with the ON101 with GWC and GWC alone strategies over a 5-year time horizon, discounting costs and effectiveness at 3% annually. Costs were in 2021 US dollars. Data were sourced from the ON101 trial and supplemented from published literature. Deterministic and probabilistic sensitivity analyses were performed to assess the uncertainty of input parameters and study generalizability. The analysis was designed and conducted from September 1, 2020, to January 31, 2022. EXPOSURES ON101 with GWC vs GWC alone. MAIN OUTCOMES AND MEASURES DFU-related complications, costs, quality-adjusted life-years (QALYs), and incremental cost-effectiveness ratio. RESULTS Patients in the hypothetical cohort had a mean age of 57 years and an uninfected DFU of 1 to 25 cm2 that was present for 4 or more weeks with a Wagner grade of 1 or 2. Over 5 years, the ON101 with GWC group vs the GWC alone group experienced more healing events, stayed for a longer time in the healing state, and had fewer infected DFUs, gangrene, and amputations (eg, 2787 additional healing events and 2766 fewer infected DFU, 72 fewer amputation, and 7 fewer gangrene events in the ON101 with GWC group vs GWC alone group). The ON101 with GWC strategy vs GWC alone yielded an additional 0.038 QALYs at an incremental cost of $571, resulting in $14 922/QALY gained. Economic results were most sensitive to healing efficacy, drug cost, and health utility of the healing state. Cost-saving results were observed in patient subgroups with poor glycemic control, larger ulcer sizes, longer ulcer durations, and current smoking. The ON101 with GWC strategy was considered cost-effective in 60% to 82% of model iterations against willingness-to-pay thresholds of $32 787/QALY gained to $98 361/QALY gained. CONCLUSIONS AND RELEVANCE In this economic evaluation study using a simulated patient cohort, the ON101 with GWC strategy represented good value compared with GWC alone for patients with DFUs from the Taiwan health care sector perspective and may be prioritized for those with high risks for disease progression of DFUs.

Clinical and Bacteriological Analyses of Biofilm-Forming Staphylococci Isolated from Diabetic Foot Ulcers. Infect Drug Resist 2023; 16:1737-1750. [PMID: 36999125 PMCID: PMC10046123 DOI: 10.2147/idr.s393724] [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: 11/30/2022] [Accepted: 01/28/2023] [Indexed: 04/01/2023] Open
Abstract
Background Diabetes mellitus is a chronic disease that is associated with increased morbidity and mortality. Unfortunately, foot ulcers and amputations due to diabetes are very common in developing countries. The purpose of this study was to characterize the clinical presentation of diabetic foot ulcer (DFU) infections, isolate the causative agent, and analyze the biofilm formation and distribution of biofilm-related genes among isolated Staphylococci. Material and Methods The study included 100 diabetic patients suffering from DFUs attending Assiut University Hospital. Swabs were collected and antimicrobial susceptibility testing of the isolates was performed. Biofilm formation was tested phenotypically among staphylococcal isolates and the frequency of different biofilm genes was analyzed by PCR. Clinical presentations of diabetic foot ulcers were correlated with bacterial genetic characteristics. Spa types were determined using DNA Gear-a software. Results Microbiological analysis showed that 94/100 of the DFUs were positive for bacterial growth. The majority of infections were polymicrobial (54%, n=54/100). Staphylococci were the most commonly detected organisms, of which S. aureus represented 37.5% (n=24/64), S. haemolyticus 23.4% (n=15/64), S. epidermidis 34.3% (n=22/64) and other CNS 4.7% (n=3/64). Interestingly, co-infection with more than one species of Staphylococci was observed in 17.1% (n=11/64) of samples. A high level of antibiotic resistance was observed, where 78.1% (n=50/64) of Staphylococci spp were multidrug-resistant (MDR). Phenotypic detection showed that all isolated Staphylococci were biofilm-formers with different grades. Analysis of biofilm-forming genes among Staphylococci showed that the most predominant genes were icaD, spa, and bap. Isolates with a higher number of biofilm-related genes were associated with strong biofilm formation. Sequencing of the spa gene in S. aureus showed that our isolates represent a collection of 17 different spa types. Conclusion The majority of DFUs in our hospital are polymicrobial. Staphylococci other than S.aureus are major contributors to infected DFUs. MDR and biofilm formation are marked among isolates, which is paralleled by the presence of different categories of virulence-related genes. All severely infected wounds were associated with either strong or intermediate biofilm formers. The severity of DFU is directly related to the number of biofilm genes.

Abstract
RATIONALE Diabetic foot ulcers (DFUs) present with different grades of ischemia and infection and are associated with high mortality and disability rates with little effective treatment. We used Fu Subcutaneous Needling (FSN) to treat 2 cases with DFUs and achieved satisfactory results. PATIENT CONCERNS Two cases of DFUs showed poor recovery after conventional wound care treatment, and case 2 was confronted with the risk of amputation. DIAGNOSIS Two patients with history of diabetes were diagnosed with DFUs, presenting with lower leg and foot ulcers. INTERVENTIONS Case 1 received 6 sessions of FSN treatment in 8 days, and case 2 received 10 sessions of FSN treatment in 14 days. OUTCOMES Case 1 completely healed from a 1 × 0.5-cm blister and a 0.5 × 0.5-cm ulcer of the right lower leg 14 days after the first FSN treatment. The ulcer area of the left foot in case 2 decreased from 6 × 7 cm to 4 × 3.5 × 0.2 cm. Three months of follow-up revealed full wound closure. LESSONS FSN is effective for healing with DFUs, and it may be used as an adjunctive healing strategy for DFUs patients when conventional treatments such as infection, glycemic control, and local ulcer care are not available.

Abstract
This study aims to systematically review and identify the related influencing factors for the recurrence of diabetic foot ulcers (DFUs)in diabetic patients. We searched PUBMED, EMBASE, Web of Science, Cochrane Library, China Biology Medicine (CBM), China National Knowledge Infrastructure (CNKI), Wan Fang and VIP databases to identify eligible studies published before March 31, 2022 to collect case-control studies or cohort studies on the related influencing factors for the recurrence of DFUs. Two reviewers independently screened the literature, and extracted data. Also, they assessed the risk of bias of the included studies using the Newcastle-Ottawa Scale. A meta-analysis was performed using RevMan5.4.1 software. 20 studies were included; 4238 patients were enrolled, in which 1567 were in the DFU recurrence group and 2671 were in the non-recurrent DFU group. Risk factors for the recurrence of DFUs included diabetic peripheral neuropathy (odds ratio [OR] = 4.05, 95% CI, 2.50-6.58, P < 0.00001), peripheral vascular disease (OR = 3.94, 95% CI, 2.65-5.84, P < 0.00001), poor blood glucose control (OR = 3.27, 95% confidence interval [CI], 2.79-3.84, P < 0.00001), plantar ulcer (OR = 3.66, 95% CI, 2.06-6.50, P < 0.00001), osteomyelitis (OR = 7.17, 95% CI, 2.29-22.47, P = 0.0007), smoking (OR = 1.98, 95% CI, 1.65-2.38, P < 0.00001), history of amputation (OR = 11.96, 95%CI, 4.60-31.14, P < 00001), multidrug-resistant bacterial infection (OR = 3.61, 95%CI, 3.13-4.17, P < 0.00001), callus (OR = 5.70, 95%CI, 1.36-23.89, P = 0.02), previous diabetic foot ulcer (OR = 4.10, 95% CI, 2.58-6.50, P < 0.00001), duration of previous diabetic foot ulcer >60d (OR = 1.02, 95% CI, 1.00-1.03, P = 0.004), history of vascular intervention (OR = 3.20, 95% CI, 2.13-4.81, P < 0.00001) and Wagner grade III/IV (OR = 4.40, 95% CI, 2.21-8.78, P < 0.0001). However, no significant differences were found in age, duration of diabetes, body mass index, total cholesterol or foot deformity. Recurrence of diabetic foot ulcers is affected by a variety of factors. Thus, we should focus on high-risk groups and take targeted interventions as soon as possible to reduce the recurrence rate of DFUs, because of the limited quality and quantity of the included studies, more rigorous studies with adequate sample sizes are needed to verify the conclusion.

Abstract
Infected diabetic foot ulcers (iDFUs) cause great concern, as they generally heal poorly and are precursive of diabetic-related foot amputation and even death. Scientists have tested various techniques in attempts to ascertain the best treatment for iDFUs; however, the results have remained inconclusive. Stem cell therapy (SCT) appears to improve iDFU through its antimicrobial impacts, yet cogent information regarding the repair of iDFUs with SCT is lacking. Herein, published articles are evaluated to report coherent information about the antimicrobial effects of SCT on the repair of iDFUs in diabetic animals and humans. In this systematic review, we searched the Scopus, Medline, Google Scholar, and Web of Science databases for relevant full-text English language articles published from 2000 to 2022 that described stem cell antimicrobial treatments, infected diabetic wounds, or ulcers. Ultimately, six preclinical and five clinical studies pertaining to the effectiveness of SCT on healing infected diabetic wounds or ulcers were selected. Some of the human studies confirmed that SCT is a promising therapy for diabetic wounds and ulcers. Notably, more controlled studies performed on animal models revealed that stem cells combined with a biostimulator such as photobiomodulation decreased colony forming units and hastened healing in infected diabetic wounds. Moreover, stem cells alone had lower therapeutic impact than when combined with a biostimulant.

Abstract
Diabetic foot ulcers (DFUs) are pathological states of tissue destruction of the foot or lower extremity in diabetic patients and are one of the serious chronic complications of diabetes mellitus. Matrix metalloproteinases (MMPs) serve crucial roles in both pathogenesis and wound healing. The primary functions of MMPs are degradation, which involves removing the disrupted extracellular matrix (ECM) during the inflammatory phase, facilitating angiogenesis and cell migration during the proliferation phase, and contracting and rebuilding the tissue during the remodeling phase. Overexpression of MMPs is a feature of DFUs. The upregulated MMPs in DFUs can cause excessive tissue degradation and impaired wound healing. Regulation of MMP levels in wounds could promote wound healing in DFUs. In this review, we talk about the roles of MMPs in DFUs and list potential methods to prevent MMPs from behaving in a manner detrimental to wound healing in DFUs.

Abstract
Background: With younger onset age of type 2 diabetes mellitus (T2DM), the incidence of diabetic foot ulcer (DFU) in young and middle-aged adults is also increasing. Elucidating the distinctive characteristics of DFU in different ages and exploring the influence of age on the prognosis of DFU are crucial to the improvement of DFU treatments. Methods: 684 patients hospitalized for DFU in the department of endocrinology were recruited and assigned into the young and middle-aged group (age <65 years old) and the elderly group (age ≥65 years old). Demographic data and clinical features were compared between two groups. Results: Compared with the elderly group, the young and middle-aged group had higher proportion of males (72.3% vs 49.6%, P < .01) and smokers (52.5% vs 35.8%, P < .01), shorter duration of diabetes mellitus (155 months vs 196 months, P < .01), higher levels of glycosylated hemoglobin (9.3% vs 8.7%, P < .01), lower ratio of ankle-brachial index <0.9 (25.8% vs 51.1%, P < .01) and higher levels of c-reactive protein and erythrocyte sedimentation rate (14 mg/L vs 10 mg/L, P < .05; 36 mm/h vs 30 mm/h, P < .05). The prevalence of diabetic peripheral neuropathy and Wagner Grade were similar in two groups. Of note, the prognosis was similar in different age groups, as there were no significant differences in the healing rate (59.7% vs 60.1%, P > .05), healing time (30 days vs 22 days, P > .05) and minor amputation rate (11.9% vs 8.7%, P > .05). Conclusions: We found that no evidence to suggest a better prognosis with younger DFU patients. Compared with elderly ones, young and middle-aged patients were characterized by a higher proportion of smoking, worse glycemic control, higher inflammatory biomarkers but less severe lower limb ischemia, indicating that smoking cessation, strict blood glucose control and early detection of infection were crucial for improving the prognosis of young and middle-aged diabetic DFU patients.

Abstract
BACKGROUND Diabetic foot and leg ulcers are a major cause of disability among patients with diabetes mellitus. A topical gel called ENERGI-F703, applied twice daily and with adenine as its active pharmaceutical ingredient, accelerated wound healing in diabetic mice. The current study evaluated the safety and efficacy of ENERGI-F703 for patients with diabetic foot and leg ulcers. METHODS This randomized, double-blind, multicenter, phase II trial recruited patients from eight medical centers in Taiwan. Patients with intractable diabetic foot and leg ulcers (Wagner Grade 1-3 without active osteomyelitis) were randomly assigned (2:1) to receive topical ENERGI-F703 gel or vehicle gel twice daily for 12 weeks or until complete ulcer closure. The investigator, enrolled patients and site personnel were masked to treatment allocation. Intention to treat (ITT) population and safety population were patient to primary analyses and safety analyses, respectively. Primary outcome was complete ulcer closure rate at the end of treatment. This trial is registered with ClinicalTrials.gov, number NCT02672436. FINDINGS Starting from March 15th, 2017 to December 26th, 2019, 141 patients were enrolled as safety population and randomized into ENERGI-F703 gel (n = 95) group or vehicle gel (n = 46) group. In ITT population, ENERGI-F703 (n = 90) and vehicle group showed ulcer closure rates of 36.7% (95% CI = 26.75% - 47.49%) and 26.2% (95% CI = 13.86% - 42.04%) with difference of 9.74 % (95 % CI = -6.74% - 26.23%) and 25% quartiles of the time to complete ulcer closure of 69 days and 84 days, respectively. There were 25 (26.3%) patients in ENERGI-F703 group and 11 (23.9%) patients in vehicle group experiencing serious adverse events and five deaths occurred during the study period, none of them related to the treatment. INTERPRETATION Our study suggests that ENERGI-F703 gel is a safe and well-tolerated treatment for chronic diabetic foot and leg ulcers. Further studies are needed to corroborate our findings in light of limitations. FUNDING Energenesis Biomedical Co., Ltd.

Rosinha P, Saraiva M, Ferreira L, Garrido S, Carvalho A, Freitas C, Amaral C, Costa L, Loureiro L, Carvalho R. A Retrospective Cohort Study on Diabetic Foot Disease: Ascertainment of Ulcer Locations by Age Group. Cureus 2022; 14:e28189. [PMID: 36158367 PMCID: PMC9491625 DOI: 10.7759/cureus.28189] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Journal Information] [Subscribe] [Scholar Register] [Accepted: 08/18/2022] [Indexed: 11/11/2022] Open
Abstract
Background and aims Diabetic foot ulcer location is a known independent predictor for cure with a better healing gradient proximal to distal. Although advanced age is one of the main factors associated with greater diabetic foot ulcer severity, there are no studies evaluating diabetic foot ulcer location specifically in the elderly population in an outpatient setting. This study evaluated diabetic foot ulcer location and age-group interactions in diabetic foot presentation. Methods A retrospective cohort study including adult patients with diabetic foot ulcers observed on their first visit to our center's Diabetic Foot Unit in 2018, divided into younger adults (YA) (18 to 64 years) and older adults (OA) (≥65 years). Results A total of 435 patients were included in the study with 159 (36.6%) in the YA, and 276 (63.4%) in the OA group. Neuro-ischemic diabetic foot ulcers were more frequent in the OA group (71.4% vs 43.4%, p<0.001). The number of patients with a history of diabetic foot ulcers was lower in the OA group (18.1% vs 25.2%, p=0.03). A smaller proportion of forefoot diabetic foot ulcers (74.9% vs 86.2%, p=0.007) and plantar location diabetic foot ulcers (9.4% vs 24.5%, p<0.001) occurred in the OA group. By univariate logistic regression analysis, we found two associations with older age: proximal (odds ratio (OR) 2.09 (1.23-3.53), p=0.006), and non-plantar (OR 3.13 (1.82-5.37), p<0.001) diabetic foot ulcer location. After adjusting for potential confounders in a multivariate analysis, older age lost the association to more proximal (OR 1.72 (0.94-3.15), p=0.081) and non-plantar (OR 1.78 (0.83-3.77), p=0.133) diabetic foot ulcer location. Conclusions There are essential age differences in diabetic foot ulcer presentation. The OA group more frequently presents neuro-ischemic diabetic foot ulcers with more proximal and non-plantar locations.

Abstract
The economic burden of neuro-ischaemic ulcers (NIU) is expected to increase because of rising prevalence of comorbidities in an aging population. We aim to estimate healthcare resources consumed by NIU patients, and to quantify the extent to which factors explain variation in cost-related outcomes. We analysed retrospective patient-level cohort data for NIU patients from a tertiary hospital registry in Singapore, from 2013 to 2017, using generalised linear regression models. The outcome variables were the length of stay per admission; inpatient and outpatient bill per admission; and, if they had an Emergency Department visit. Cost outcomes were reported in Singapore dollars (S$). A total of 1682 patients were included, and the mean age was 69.9 years (±13.0). An average patient incurred a length of stay of 38.7 days, 7.9 inpatient dressing sessions, an inpatient bill of S$33 096, 11.3 outpatient dressing sessions, and an outpatient bill of S$8780. Inpatient services per patient cost 73.5% higher than outpatient services. NIU patients with multiple (>3) comorbid conditions, peripheral artery disease, or chronic kidney disease incurred longer hospitalisation and higher inpatient bill. Patients with diabetes mellitus and coronary artery disease had higher odds of incurring an ED visit. Patients with coronary artery disease, hyperlipidaemia, kidney complications, or obesity incurred higher outpatient bills. NIU treatment imposes a significant economic burden, especially with inpatient services.

Abstract
Pathologic diabetic wound healing is caused by sequential and progressive deterioration of hemostasis, inflammation, proliferation, and resolution/remodeling. Cellular senescence promotes wound healing; however, diabetic wounds exhibit low levels of senescent factors and accumulate senescent cells, which impair the healing process. Here we show that the number of p15INK4B + PDGFRα + senescent mesenchymal cells in adipose tissue increases transiently during early phases of wound healing in both non-diabetic mice and humans. Transplantation of adipose tissue from diabetic mice into non-diabetic mice results in impaired wound healing and an altered cellular senescence–associated secretory phenotype (SASP), suggesting that insufficient induction of adipose tissue senescence after injury is a pathological mechanism of diabetic wound healing. These results provide insight into how regulation of senescence in adipose tissue contributes to wound healing and could constitute a basis for developing therapeutic treatment for wound healing impairment in diabetes. Type-2 diabetic adipose tissue impairs transient senescence during wound healing with expression of different components of the senescence-associated secretory phenotype (SASP), and this is associated with deteriorated wound healing.

Abstract
Diabetic foot ulcer (DFU), one of the most serious complications of diabetes mellitus, is associated with a high amputation rate and decreased life quality. The impact of blood serum proteins on the occurrence and development of DFU has attracted a lot of interest. In this study, we aimed to define and compare the serum proteome of patients with DFU and healthy control (HC) to provide new insights into DFU pathogenesis. DFU patients and age- and sex-matched HCs were enrolled in this study (n = 54). We screened alterations in blood serum proteins from DFU patients and HC using a tandem mass tag (TMT) method based on liquid chromatography-mass spectrometry (LC-MS/MS) quantitative proteomics, and the differentially expressed proteins (DEPs) were further validated by parallel reaction monitoring (PRM) and enzyme-linked immunosorbent assay (ELISA). A total of 173 DEPs (100 up-regulated and 73 down-regulated) were identified between the DFU and HC groups (P < 0.05). Proteomic and bioinformatics analyses indicated that the proteins in the DFU group were mainly related to extracellular matrix (ECM)-receptor interaction and complement and coagulation cascades. The up-regulated DEPs were further verified by PRM and ELISA. LRG1, CD5L, CRP, IGHA1, and LBP were proved upregulated in DFU and these proteins are mainly related to immune response and complement activation. Our findings help to provide a more comprehensive understanding of the pathogenesis of DFU and new insight into potential therapeutic targets.

Abstract
PURPOSE Free triiodothyronine (FT3) and FT3/free thyroxine (FT4) ratio have been associated with mortality in various diseases. However, no study to date has identified a link between FT3, FT3/FT4 ratio and all-cause mortality in patients with diabetic foot ulcers (DFUs). This study aimed to investigate this relationship. METHODS This retrospective cohort study included 726 patients diagnosed with DFUs in a public hospital from January 2015 to October 2019. Patients were classified by the optimal cut-off values of the FT3 and FT3/FT4 ratio, respectively. The association of FT3 and FT3/FT4 ratio with all-cause mortality was evaluated in a multivariable cox regression model. Directed acyclic graphs were used to assess the minimally sufficient sets of confounding variables. RESULTS Log rank tests indicated that patients with low FT3 and FT3/FT4 ratio had lower overall survival rates (all p < 0.001). The adjusted HRs for all-cause mortality were 0.48 (95% CI: 0.32-0.73, P = 0.001) when comparing high versus low FT3 and 0.47 (95% CI: 0.32-0.70, P < 0.001) when comparing high versus low FT3/FT4 ratio. Subgroup analyses showed that these associations existed only in elderly patients (≥65 years) and women, after adjustment. In men, only high FT3/FT4 ratio was associated with low all-cause mortality, after adjustment. CONCLUSION Routine assessment of FT3 and FT3/FT4 ratio may be a simple and effective way to identify high-risk patients with DFUs, especially in elderly patients and women.

Abstract
BACKGROUND AND AIMS Classification of wound severity is important in medical care decisions specially in diabetic patients. The Wagner Scale provides a structure to determine the severity of a wound by examining its depth and extent. The adequate reliability of this instrument, like other instruments for measuring health status, is important. So, the aim of this review is to report evidence on the reliability of the Wagner scale. METHOD A comprehensive search was performed in databases. Observational studies that assessed the reliability of the Wagner scale, with statistical measures, were included. Methodological quality of studies was evaluated with the COSMIN checklist. Finally, we report the reliability measurements, narratively. RESULTS We assessed 7 studies. In all studies 1873 subjects participated. Methodological quality was good only in one study. In two studies used of weighted kappa (Inter Observer Reliability) that reliability was in median level in both studies. The relation between Wagner score and amputation were report in two studies that measured by X2trend and regression analysis. In four measurements, reported the correlation between Wagner with ulcer healing by X2trend, Log Rank, Kaplan-Meier, and inter quartile range. CONCLUSION It can be confirmed that the reliability of the Wagner scale is appropriate and this tool is recommended to evaluate the severity of the wounds specially in diabetic patients. It should also be noted that the user of the scale must be trained. In future studies, it is recommended to use appropriate methodology and complete reports for the reliability of Wagner scale.

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
Diabetes‐related lower extremity amputations are an enormous burden on global health care and social resources because of the rapid worldwide growth of the diabetic population. This research aimed to determine risk factors that predict major amputation and analyse the time interval from first hospitalisation to amputation by using standard management protocols and Kaplan–Meier survival curves. Data from 246 patients with diabetes mellitus and diabetic foot ulcers from the Division of Plastic and Reconstructive Surgery of the Department of Surgery at XXX Hospital between January 2016 and May 2020 were analysed. Univariate and multivariate analyses of 44 potential risk factors, including invasive ulcer depth and C‐reactive protein levels, showed statistically significant differences for those at increased risk for major amputation. The median time from hospitalisation to lower extremity amputation was approximately 35 days. Most patients with abnormal C‐reactive protein levels and approximately 70% of patients with ulcers invading the bone were at risk for lower extremity amputations within 35 days. Therefore, invasive ulcer depth and C‐reactive protein levels are significant risk factors. Other potential risk factors for major amputation and the time intervals from first hospitalisation to amputation should be analysed to establish further prediction strategies.

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.

Abstract
IMPORTANCE Delayed healing of diabetic foot ulcers (DFUs) is known to be caused by dysregulated M1/M2-type macrophages, and restoring the balance between these macrophage types plays a critical role in healing. However, drugs used to regulate M1/M2 macrophages have not yet been studied in large randomized clinical trials. OBJECTIVE To compare the topical application of ON101 cream with use of an absorbent dressing (Hydrofiber; ConvaTec Ltd) when treating DFUs. DESIGN, SETTING, AND PARTICIPANTS This multicenter, evaluator-blinded, phase 3 randomized clinical trial was performed in 21 clinical and medical centers across the US, China, and Taiwan from November 23, 2012, to May 11, 2020. Eligible patients with debrided DFUs of 1 to 25 cm2 present for at least 4 weeks and with Wagner grade 1 or 2 were randomized 1:1 to receive ON101 or control absorbent dressings. INTERVENTIONS Twice-daily applications of ON101 or a absorbent dressing changed once daily or 2 to 3 times a week for 16 weeks, with a 12-week follow-up. MAIN OUTCOMES AND MEASURES The primary outcome was the incidence of complete healing, defined as complete re-epithelialization at 2 consecutive visits during the treatment period assessed on the full-analysis set (FAS) of all participants with postrandomization data collected. Safety outcomes included assessment of the incidences of adverse events, clinical laboratory values, and vital signs. RESULTS In the FAS, 236 eligible patients (175 men [74.2%]; mean [SD] age, 57.0 [10.9] years; mean [SD] glycated hemoglobin level, 8.1% [1.6%]) with DFUs classified as Wagner grade 1 or 2 (mean [SD] ulcer area, 4.8 [4.4] cm2) were randomized to receive either the ON101 cream (n = 122) or the absorbent dressing (n = 114) for as long as 16 weeks. The incidence of complete healing in the FAS included 74 patients (60.7%) in the ON101 group and 40 (35.1%) in the comparator group during the 16-week treatment period (difference, 25.6 percentage points; odds ratio, 2.84; 95% CI, 1.66-4.84; P < .001). A total of 7 (5.7%) treatment-emergent adverse events occurred in the ON101 group vs 5 (4.4%) in the comparator group. No treatment-related serious adverse events occurred in the ON101 group vs 1 (0.9%) in the comparator group. CONCLUSIONS AND RELEVANCE In this multicenter randomized clinical trial, ON101 exhibited better healing efficacy than absorbent dressing alone in the treatment of DFUs and showed consistent efficacy among all patients, including those with DFU-related risk factors (glycated hemoglobin level, ≥9%; ulcer area, >5 cm2; and DFU duration, ≥6 months). TRIAL REGISTRATION ClinicalTrials.gov Identifier: NCT01898923.

Association between heart rate-corrected QT interval and severe peripheral arterial disease in patients with type 2 diabetes and foot ulcers. Endocr Connect 2021; 10:845-851. [PMID: 34223825 PMCID: PMC8346192 DOI: 10.1530/ec-21-0140] [Citation(s) in RCA: 6] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 06/20/2021] [Accepted: 07/05/2021] [Indexed: 12/12/2022]
Abstract
BACKGROUND A prolonged heart rate-corrected QT interval (QTc) has been associated with peripheral artery disease (PAD) in the general population. However, no study to date has identified a link between prolonged QTc and the severity of PAD in patients with diabetes mellitus and foot ulcers (DFUs). This study aimed to investigate this relationship. METHODS This multicenter study enrolled 281 patients with DFUs. The severity of PAD was classified into no severe PAD group (without stenosis or occlusion) and severe PAD group (with stenosis or occlusion) based on duplex ultrasonography. The association of prolonged QTc with severe PAD was evaluated in a multivariable mixed-effect logistic regression model, with the hospital as a random effect. Directed acyclic graphs were used to drive the selection of variables to fit the regression model. RESULTS Patients with severe PAD had longer QTc than those without. Based on the multivariable mixed-effect logistic regression model, a prolonged QTc was positively associated with severe PAD (odds ratio (OR) = 2.61; 95% CI: 1.07-6.35) and severe DFUs (Wagner grade score ≥ 3) (OR = 2.87; 95% CI: 1.42-5.81). CONCLUSIONS A prolonged QTc was associated with severe PAD in patients with DFUs. Further research is required to ascertain whether the association is causal.

Non-vascular contributing factors of diabetic foot ulcer severity in national referral hospital of Indonesia. J Diabetes Metab Disord 2021; 20:805-813. [PMID: 34178865 PMCID: PMC8212257 DOI: 10.1007/s40200-021-00827-x] [Citation(s) in RCA: 4] [Impact Index Per Article: 1.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 02/11/2021] [Accepted: 05/30/2021] [Indexed: 10/21/2022]
Abstract
PURPOSE Diabetic foot ulcer (DFU) is a common chronic complication of type 2 diabetes mellitus (T2DM) in Indonesia, with a prevalence of 7.3%. However, the characteristics of these patients remain unclear. We investigated the characteristics of patients with DFU without peripheral arterial disease (PAD) and analyzed non-vascular factors related to severity of DFU in a tertiary care national referral hospital in Indonesia. METHODS This was a cross-sectional study including 123 hemodynamically stable DFU patients without PAD recruited from Dr. Cipto Mangunkusumo National General Hospital, Jakarta, Indonesia from 2010-2015. RESULTS DFU patients were predominantly over 50 years old (75.6%) and diagnosed with T2DM for 5 years with poor glycemic control (82.7%) and peripheral neuropathy (91.3%). Most patients had anemia (86.7%), leukocytosis (84.6%), and were undernourished, as characterized by a low lipid profile (90.8%) and hypoalbuminemia (83.7%). Most had extensive size of ulcer at the initial visit, with a median size of 16.23 (2.92-60.16) cm2. Ulcers were mostly located of the forefoot (62.5%) and were caused by mechanical trauma (46.2%). Bivariate analysis revealed that significant factors for the development of DFU were related to DFU size, including duration of T2DM (p = 0.04), leukocyte levels (p = < 0.01), and thrombocyte levels (p = < 0.01). Multivariate analysis showed leucocyte (p = 0.03) and thrombocyte (p = 0.023) had significantly correlated with DFU severity. CONCLUSION Leucocyte and thrombocyte may be the greatest contributing non-vascular factors for severity of DFU in Indonesia.

Abstract
PURPOSE Smoking cessation reduces morbidity and mortality of cardiovascular diseases. The purpose of this study was to evaluate the effect during smoking cessation treatment on glycemic control and cardiometabolic risk factors, including blood pressure and lipid levels, in patients with type 2 diabetes. PATIENTS AND METHODS This retrospective cohort study included patients with type 2 diabetes who participated in a smoking cessation program, which comprised health education and medication prescription at an outpatient clinic in combination with a 3-month follow-up by phone. Data on patient background characteristics, cardiometabolic factors, smoking status, body weight, and body mass index before and after the program were collected for analysis. RESULTS The analysis included 241 participants with an average age of 58.6 ± 10.6 years. The rate of successful cessation at three months was 34.0%. Compared with the baseline levels, there were significant decreases in the levels of fasting plasma glucose (10.0 ± 46.8 mg/dL, P = 0.001), HbA1c (0.3 ± 1.4%, P = 0.004), systolic blood pressure (4.6 ± 17.5 mmHg, P < 0.001), diastolic blood pressure (2.9 ± 11.3 mmHg, P < 0.001), and total cholesterol (7.9 ± 42.8 mg/dL, P = 0.020) after participation in the smoking cessation program while there was no significant difference in body weight (0.1 ± 1.2 kg, P = 0.444). After adjustment for covariates, the decreases in HbA1c and total cholesterol levels were significantly better in younger participants and higher baseline nicotine dependence scores were associated with decreases in the levels of blood pressure, fasting plasma glucose, and triglycerides. However, the decrease in smoking amount was not associated with the changes in cardiometabolic factors. CONCLUSION Participation in a smoking cessation program was associated with improvements in glycemic control and cardiometabolic risk factors in patients with type 2 diabetes. The observed improvements were associated with participation in the program but not with the decrease in smoking amount.

Abstract
This study was conducted to determine the effects of curcumin intake on wound healing and metabolic status in patients with diabetic foot ulcer (DFU). The current randomized, double-blind, placebo-controlled trial was conducted among 60 patients with grade 3 DFU. Participants were randomly allocated into two groups (30 participants each group), received either 80 mg nanocurcumin daily for 12 weeks or placebo. Primary endpoints in this study were serum insulin levels and insulin resistance. Curcumin intake significantly decreased fasting plasma glucose (p = .02), insulin (p = .01), insulin resistance (p = .02), and significantly increased insulin sensitivity (p = .008) compared with the placebo. Moreover, curcumin intake led to a significant reduction in total- (p < .001), LDL-cholesterol (p < .001), and a significant increase in total antioxidant capacity (TAC) (p < .001) and total glutathione (GSH) (p = .01) compared with the placebo. However, there was no significant improvement in wound healing parameters. Overall, our study demonstrated that nanocurcumin intake in patients with DFU resulted in a significant improvement of glycemic control, total- and LDL-cholesterol, TAC, and GSH but did not affect the indicators of ulcer size.
