Microbiological profile of diabetic foot infections in China and worldwide: a 20-year systematic review.

Introduction: Pathogens causing diabetic foot infections (DFIs) vary by region globally; however, knowledge of the causative organism is essential for effective empirical treatment. We aimed to determine the incidence and antibiotic susceptibility of DFI pathogens worldwide, focusing on Asia and China. Methods: Through a comprehensive literature search, we identified published studies on organisms isolated from DFI wounds from January 2000 to December 2020. Results: Based on our inclusion criteria, we analyzed 245 studies that cumulatively reported 38,744 patients and 41,427 isolated microorganisms. DFI pathogens varied according to time and region. Over time, the incidence of Gram-positive and Gram-negative aerobic bacteria have decreased and increased, respectively. America and Asia have the highest (62.74%) and lowest (44.82%) incidence of Gram-negative bacteria, respectively. Africa has the highest incidence (26.90%) of methicillin-resistant Staphylococcus aureus. Asia has the highest incidence (49.36%) of Gram-negative aerobic bacteria with species infection rates as follows: Escherichia coli, 10.77%; Enterobacter spp., 3.95%; and Pseudomonas aeruginosa, 11.08%, with higher local rates in China and Southeast Asia. Linezolid, vancomycin, and teicoplanin were the most active agents against Gram-positive aerobes, while imipenem and cefoperazone-sulbactam were the most active agents against Gram-negative aerobes. Discussion: This systematic review showed that over 20 years, the pathogens causing DFIs varied considerably over time and region. This data may inform local clinical guidelines on empirical antibiotic therapy for DFI in China and globally. Regular large-scale epidemiological studies are necessary to identify trends in DFI pathogenic bacteria.

Analysis of Circulating miRNA Expression Profiles in Type 2 Diabetes Patients with Diabetic Foot Complications.

Type 2 diabetes mellitus (T2DM) is associated with various complications, including diabetic foot, which can lead to significant morbidity and mortality. Non-healing foot ulcers in diabetic patients are a major risk factor for infections and amputations. Despite conventional treatments, which have limited efficacy, there is a need for more effective therapies. MicroRNAs (miRs) are small non-coding RNAs that play a role in gene expression and have been implicated in diabetic wound healing. miR expression was analyzed through RT-qPCR in 41 diabetic foot Mexican patients and 50 controls. Diabetic foot patients showed significant increases in plasma levels of miR-17-5p (p = 0.001), miR-191-5p (p = 0.001), let-7e-5p (p = 0.001), and miR-33a-5p (p = 0.005) when compared to controls. Elevated levels of miR-17, miR-191, and miR-121 correlated with higher glucose levels in patients with diabetic foot ulcers (r = 0.30, p = 0.004; r = 0.25, p = 0.01; and r = 0.21, p = 0.05, respectively). Levels of miR-17 showed the highest diagnostic potential (AUC 0.903, p = 0.0001). These findings underscore the possible role of these miRs in developing diabetes complications. Our study suggests that high miR-17, miR-191, and miR-121 expression is strongly associated with higher glucose levels and the development of diabetic foot ulcers.

Onychomycosis in Diabetics: Prevalence, Clinical Features and Spectrum of Causative Fungi in South-Eastern Nigeria.

INTRODUCTION: Onychomycosis is a fungal infection of the nail unit and one of the common nail diseases that occurs commonly in diabetic patients. It poses a threat of diabetic foot complications to diabetics and negatively affects the quality of life of the patients. OBJECTIVES: The overall aim of the study was to determine the prevalence and clinical features of onychomycosis in diabetics, as well as the spectrum of causative fungi in Nigeria as compared with age and sex-matched controls. METHODOLOGY: This was a hospital-based, comparative cross-sectional study. One hundred and fifty consecutive adult diabetics and 150 healthy controls (accompanied persons and staff) matched for age and sex were recruited from the Diabetic Clinics and the Dermatology Clinic of the University of Nigeria Teaching Hospital, Ituku-Ozalla. The participants were interviewed using a pre-tested structured questionnaire, nail scrapings were collected for fungal studies, and clippings for nail histopathology using Periodic Acid Schiff. RESULTS: The prevalence of onychomycosis among DM subjects was 45.3% vs. 35.3% in controls, which was not statistically significant (P value 0.078). Distal-lateral subungual onychomycosis was the most common clinical type in both study groups and presented mainly with nail discolouration, onycholysis, and subungual hyperkeratosis. The most common fungi isolated were dermatophytes (Trichophyton soudanense), non-dermatophytes (Aspergillus spp.), and Candida species (Candida albicans). CONCLUSION: Onychomycosis in diabetics is a very common nail disorder in the South-Eastern part of Nigeria with a high prevalence. The presence of foot ulcers was associated with onychomycosis in diabetics, and they were more likely to have non-dermatophytic onychomycosis.

INTRODUCTION: L'onychomycose est une infection fongique de l'unité de l'ongle et l'une des maladies des ongles les plus courantes chez les patients diabétiques. Elle pose une menace de complications du pied diabétique et affecte négativement la qualité de vie des patients. OBJECTIFS: L'objectif général de l'étude était de déterminer la prévalence et les caractéristiques cliniques de l'onychomycose chez les diabétiques, ainsi que le spectre des champignons causaux au Nigeria par rapport à un groupe témoin apparié selon l'âge et le sexe. MÉTHODOLOGIE: Il s'agissait d'une étude transversale comparative réalisée en milieu hospitalier. Cent cinquante diabétiques adultes consécutifs et 150 témoins sains (personnes accompagnatrices et personnel) appariés selon l'âge et le sexe ont été recrutés dans les cliniques de diabète et la clinique de dermatologie de l'Hôpital Universitaire du Nigeria à Ituku-Ozalla. Les participants ont été interrogés à l'aide d'un questionnaire structuré pré-testé, des échantillons de grattage d'ongles ont été prélevés pour des études fongiques, et des échantillons pour l'histopathologie des ongles utilisant l'acide périodique de Schiff. RÉSULTATS: La prévalence de l'onychomycose chez les sujets atteints de diabète était de 45,3 % contre 35,3 % chez les témoins, ce qui n'était pas statistiquement significatif (valeur de p 0,078). L'onychomycose sousunguéale distale-latérale était le type clinique le plus courant dans les deux groupes d'étude et se manifestait principalement par une décoloration des ongles, une onycholyse et une hyperkératose sousunguéale. Les champignons les plus couramment isolés étaient les dermatophytes (Trichophyton soudanense), les non-dermatophytes (Aspergillus spp.) et les espèces de Candida (Candida albicans). CONCLUSION: L'onychomycose chez les diabétiques est un trouble des ongles très courant dans le sud-est du Nigeria avec une prévalence élevée. La présence d'ulcères du pied était associée à l'onychomycose chez les diabétiques, et ils étaient plus susceptibles de présenter une onychomycose non-dermatophytique.

[Development of a prediction model for incidence of diabetic foot in patients with type 2 diabetes and its application based on a local health data platform].

Objective: To construct a diabetes foot prediction model for adult patients with type 2 diabetes based on retrospective cohort study using data from a regional health data platform. Methods: Using Yinzhou Health Information Platform of Ningbo, adult patients with newly diagnosed type 2 diabetes from January 1, 2015 to December 31, 2022 were included in this study and divided randomly the train and test sets according to the ratio of 7∶3. LASSO regression model and bidirectional stepwise regression model were used to identify risk factors, and model comparisons were conducted with net reclassification index, integrated discrimination improvement and concordance index. Univariate and multivariate Cox proportional hazard regression models were constructed, and a nomogram plot was drawn. Area under the curve (AUC) was calculated as a discriminant evaluation indicator for model validation test its calibration ability, and calibration curves were drawn to test its calibration ability. Results: No significant difference existed between LASSO regression model and bidirectional stepwise regression model, but the better bidirectional stepwise regression model was selected as the final model. The risk factors included age of onset, gender, hemoglobin A1c, estimated glomerular filtration rate, taking angiotensin receptor blocker and smoking history. AUC values (95%CI) of risk outcome prediction at year 5 and 7 were 0.700 (0.650-0.749) and 0.715(0.668-0.762) for the train set and 0.738 (0.667-0.801) and 0.723 (0.663-0.783) for the test set, respectively. The calibration curves were close to the ideal curve, and the model discrimination and calibration powers were both good. Conclusions: This study established a convenient prediction model for diabetic foot and classified the risk levels. The model has strong interpretability, good discrimination power, and satisfactory calibration and can be used to predict the incidence of diabetes foot in adult patients with type 2 diabetes to provide a basis for self-assessment and clinical prediction of diabetic foot disease risk.

Exploring the psychosocial burden of foot complications in diabetes: A cross-sectional survey and qualitative interview study in a United Kingdom coastal community.

BACKGROUND: Foot complications in diabetes are common and destructive, resulting in substantial healthcare costs and high rates of morbidity. Coastal areas have a significantly higher burden of disease. People with diabetes experience disproportionately high rates of psychological health issues, including anxiety, depression and diabetes distress. These can affect self-management and concordance with preventive measures and treatments of foot complications, negatively impacting on outcomes. Access to psychological health services is variable across the United Kingdom and there is a paucity of high-quality evidence for the effectiveness of treatments for diabetes distress. This study aimed to explore experiences of psychosocial burden and perceptions and experiences of psychosocial support, among patients with diabetes and foot complications living in a coastal area. METHODS: Patients were eligible to participate if they had experienced diabetes-related foot complications (amputation, ulceration and/or Charcot neuroarthropathy) within the last 5 years and scored positive for diabetes distress on a validated screening tool (DDS2). Eligible patients completed cross-sectional questionnaires describing symptoms of diabetes distress (DDS17), anxiety (GAD-7) and depression (PHQ-9) and to take part in a face-to-face, semi-structured interview. Questionnaires were analysed using frequencies and interviews were analysed using reflexive thematic analysis. RESULTS: A total of 183 patients completed the DDS2 screening questionnaire. Of these, 56 (30.6%) screened positive for diabetes distress. Twenty-seven patients completed DDS17, GAD-7 and PHQ-9 questionnaires. Eleven (40.7%) participants indicated high levels of diabetes distress and four (14.8%) indicated moderate distress. Seventeen participants (age range 52-81 years; 12 men) took part in an interview. Four key themes were identified: impact of living with foot problems; emotional consequences of foot problems; experiences and perceptions of psychological support; and strategies to cope with the emotional impact of foot problems. CONCLUSION: Diabetes distress was prevalent among patients with diabetes-related foot complications. Foot problems impacted on participants' daily activities, social lives and ability to work. Despite expressing feelings of ongoing fear, worry and depression relating to their foot problems, only one participant had accessed formal psychological support. Many participants relied on talking to podiatrists at routine appointments and described developing various strategies to cope. The psychosocial burden of living with foot complications in diabetes must not be overlooked by health professionals. Findings from this study can inform the design of future services and interventions.

The incidence of lower extremity amputation and its associated risk factors in patients with diabetic foot ulcers: A meta-analysis.

This study analysed the incidence of lower extremity amputation and its associated risk factors in patients with diabetic foot ulcers. This study systematically searched both Chinese and English databases, including CNKI, Wanfang, VIP, PubMed, EMBASE and Web of Science, to identify cohort studies related to lower extremity amputation and associated risk factors in patients with diabetic foot ulcers up to October 2023. The patients were stratified based on whether they underwent lower extremity amputation, and relevant data, including basic information, patient characteristics, complications, comorbidities and pertinent laboratory test data, were extracted from the included studies. The literature quality assessment in this study utilized the Newcastle-Ottawa Scale to screen for high-quality literature, resulting in the inclusion of 16 cohort studies, all of which were of at least moderate quality. Meta-analysis of outcome indicators was conducted using the Stata 14.0 software. The results indicate that the overall amputation rate of lower extremities in patients with diabetic foot ulcers is 31% (0.25, 0.38). Among the 16 variables evaluated, gender (male), smoking history, body mass index (BMI), hypertension, cardiovascular disease, kidney disease, white blood cell count, haemoglobin and albumin levels were found to be correlated with the occurrence of lower extremity amputation in patients with diabetic foot ulcers. However, no significant correlation was observed between age, diabetes type, duration of diabetes, stroke, glycosylated haemoglobin, creatinine and total cholesterol levels and lower extremity amputation in patients with diabetic foot ulcers. This meta-analysis indicates that the overall amputation rate in patients with diabetic foot ulcers is 31%. Factors such as gender (male), smoking history, high BMI, hypertension, cardiovascular disease, kidney disease, white blood cell count, haemoglobin and albumin levels are identified as significant risk factors for lower extremity amputation in diabetic foot ulcer patients. These findings suggest that attention should be focused on these risk factors in patients with diabetic foot ulcers to reduce the risk of lower extremity amputation. Therefore, preventive and intervention measures targeting these risk factors are of significant importance in clinical practice.

Affordable web-based foot-ankle exercise program proves effective for diabetic foot care in a randomized controlled trial with economic evaluation.

The aim of this study was to shed light on a crucial issue through a comprehensive evaluation of the cost-effectiveness and cost-utility of a cutting-edge web-based foot-ankle therapeutic exercise program (SOPeD) designed for treating modifiable risk factors for ulcer prevention in individuals with diabetes-related peripheral neuropathy (DPN). In this randomized controlled trial, 62 participants diagnosed with DPN were assigned to the SOPeD software or received usual care for diabetic foot. Primary outcomes were DPN symptoms and severity, foot pain and function, and quality-adjusted life years (QALYs). Between-group comparisons provided 95% confidence intervals. The study also calculated incremental cost-effectiveness and cost-utility ratios (ICERs), analyzed direct costs from a healthcare perspective, and performed a sensitivity analysis to assess uncertainty. The web-based intervention effectively reduced foot pain, improved foot function and showed favorable cost-effectiveness, with ICERs ranging from (USD) $5.37-$148.71 per improvement in different outcomes. There is a high likelihood of cost-effectiveness for improving DPN symptoms and severity, foot pain, and function, even when the minimum willingness-to-pay threshold was set at $1000.00 USD. However, the intervention did not prove to be cost-effective in terms of QALYs. This study reveals SOPeD's effectiveness in reducing foot pain, improving foot function, and demonstrating cost-effectiveness in enhancing functional and clinical outcomes. SOPeD stands as a potential game-changer for modifiable risk factors for ulcers, with our findings indicating a feasible and balanced integration into public health systems. Further studies and considerations are vital for informed decisions to stakeholders and the successful implementation of this preventive program on a larger scale.Trial Registration: ClinicalTrials.gov, NCT04011267.

Molecular characterization of Pseudomonas aeruginosa from diabetic foot infections in Tunisia.

Background. Pseudomonas aeruginosa is an invasive organism that frequently causes severe tissue damage in diabetic foot ulcers.Gap statement. The characterisation of P. aeruginosa strains isolated from diabetic foot infections has not been carried out in Tunisia.Purpose. The aim was to determine the prevalence of P. aeruginosa isolated from patients with diabetic foot infections (DFIs) in Tunisia and to characterize their resistance, virulence and molecular typing.Methods. Patients with DFIs admitted to the diabetes department of the International Hospital Centre of Tunisia, from September 2019 to April 2021, were included in this prospective study. P. aeruginosa were obtained from the wound swabs, aspiration and soft tissue biopsies during routine clinical care and were confirmed by matrix-assisted laser desorption/ionization time-of-flight mass spectrometry. Antimicrobial susceptibility testing, serotyping, integron and OprD characterization, virulence, biofilm production, pigment quantification, elastase activity and molecular typing were analysed in all recovered P. aeruginosa isolates by phenotypic tests, specific PCRs, sequencing, pulsed-field gel electrophoresis (PFGE) and multilocus sequence typing.Results. Sixteen P. aeruginosa isolates (16.3 %) were recovered from 98 samples of 78 diabetic patients and were classified into 6 serotypes (O:11 the most frequent), 11 different PFGE patterns and 10 sequence types (three of them new ones). The high-risk clone ST235 was found in two isolates. The highest resistance percentages were observed to netilmicin (69 %) and cefepime (43.8 %). Four multidrug-resistant (MDR) isolates (25 %) were detected, three of them being carbapenem-resistant. The ST235-MDR strain harboured the In51 class 1 integron (intI1 +aadA6+orfD+qacED1-sul1). According to the detection of 14 genes involved in virulence or quorum sensing, 5 virulotypes were observed, including 5 exoU-positive, 9 exoS-positive and 2 exoU/exoS-positive strains. The lasR gene was truncated by ISPpu21 insertion sequence in one isolate, and a deletion of 64 bp in the rhlR gene was detected in the ST235-MDR strain. Low biofilm, pyoverdine and elastase production were detected in all P. aeruginosa; however, the lasR-truncated strain showed a chronic infection phenotype characterized by loss of serotype-specific antigenicity, high production of phenazines and high biofilm formation.Conclusions. Our study demonstrated for the first time the prevalence and the molecular characterization of P. aeruginosa strains from DFIs in Tunisia, showing a high genetic diversity, moderate antimicrobial resistance, but a high number of virulence-related traits, highlighting their pathological importance.

Efficacy of autologous platelet-rich plasma gel in patients with hard-to-heal diabetic foot ulcers: a multicentre study in Japan.

OBJECTIVE: To evaluate the healing outcome of a platelet-rich plasma (PRP) gel prepared using TKKT01 (a wound care device to prepare the PRP gel) in patients with hard-to-heal diabetic foot ulcers (DFUs) and who showed an inadequate response to ≥4 weeks of standard of care (SoC). METHOD: This open-label, single-arm, multicentre study was conducted in 15 centres in Japan. Eligible patients received PRP gel treatment twice a week for eight weeks, followed by a final evaluation after the completion of week 8 (day 57). The primary endpoint was the percentage of patients who achieved ≥50% reduction in wound radius at the final evaluation (achievement criterion, ≥60% of patients). Secondary endpoints included: wound area and volume reduction rates; time to possible wound closure by secondary intention; time to possible wound closure using a relatively simple procedure (e.g., skin graft and suture); and safety at the final evaluation. RESULTS: A total of 54 patients were included in the full analysis set, with 47 patients included in the per protocol set; the primary endpoint was met in 38/47 (80.9%) (95% confidence interval: 66.7-90.9%) patients who achieved ≥50% wound radius reduction at the final evaluation. High rates of wound area (72.8%) and volume (92.7%) reduction were observed at the final evaluation. The median time to possible wound closure by secondary intention and by use of a relatively simple procedure was 57 and 43 days, respectively. Complete wound closure at the final evaluation was achieved in 27 (57.4%) patients. No safety concerns were raised. CONCLUSION: In this study, the efficacy and safety of PRP gel treatment with TKKT01 in patients with hard-to-heal DFUs in Japan were confirmed by our findings.

Correlation of ankle-wrist pressure index with ankle-brachial pressure index to assess lower limb perfusion in diabetic foot ulcer: a pilot study.

OBJECTIVE: The presence of peripheral artery disease (PAD) in patients with diabetic foot ulcers (DFUs) is a significant risk factor for chronicity and amputation. Ankle-brachial pressure index (ABPI) is a screening tool for PAD. Brachial systolic pressure measurement, used as a denominator in the calculation of ABPI, produces inaccurate results in patients with obesity and the presence of heavy clothing. The wrist, however, is easily accessible, and the ankle-wrist pressure index (AWPI), if comparable with ABPI, may be useful in screening selected patients. This study aimed to assess the efficacy of AWPI in diagnosing perfusion in DFUs and compare it to ABPI in patients with DFUs. METHOD: ABPI and AWPI were calculated by measuring systolic blood pressure in the arteries of the ankle, arm and wrist with a handheld Doppler. Actual perfusion was determined by the presence or absence of PAD by duplex ultrasound. RESULTS: A total of 46 lower extremities in 41 patients were studied. The prevalence of PAD was 61%. Duplex ultrasound confirmed that the sensitivity of ABPI and AWPI in detecting PAD in patients with DFUs was 67.9% and 71.4% respectively, whereas the specificity of ABPI and AWPI was 94.4% and 88.9% respectively. On receiver operating characteristic analysis, the area under the curve of ABPI and AWPI was 0.804 and 0.795, respectively. A statistically significant positive correlation between ABPI and AWPI was found (r=0.986; p<0.001). CONCLUSION: There was a good correlation between ABPI and AWPI over a wide range of values. ABPI and AWPI may have a similar role in predicting perfusion in patients with DFUs. AWPI could be used in place of ABPI in selected patients in whom measuring ABPI may be difficult.

Knowledge, attitudes and practices on diabetic foot care among nurses in Kimberley, South Africa.

BACKGROUND:  Diabetic foot is a dangerous complication of diabetes and can lead to high morbidity and mortality. As essential team members of the healthcare system, nurses play an important role in diabetic foot management and are indispensable in patients' education to prevent diabetic foot. The study assessed nurses' knowledge, attitudes and practices regarding diabetic foot care in Sol Plaatje primary health care centres in the Northern Cape: Sol Plaatje's 14 district municipality clinics, Kimberley, Northern Cape. METHODS:  This was a descriptive cross-sectional analytical study. A questionnaire assessed nurses' knowledge, practices and attitudes towards diabetic foot care in the above setting. RESULTS:  A total of 128 professionals, enrolled and auxiliary nurses who are providing primary care to patients within the 14 clinics in the Sol-Plaatje sub-district were recruited for the study. Hundred and five participants completed the self-administered questionnaires. The majority (95%) were females and 58.1% knew that South African Diabetic Foot Guidelines existed, while 57.7% had read them. About 57% did not know about the 60-s diabetic foot screening tool, and 67% did not know the 10 g monofilament test. Approximately 29.8% had never attended a class on diabetic foot care and 85.6% required training on diabetic foot care. CONCLUSION:  This study revealed that the majority of nurses working in the Sol-Plaatje sub-district primary health care centres are knowledgeable of the diabetic foot guidelines for primary care. However, there is a need for ongoing education on diabetic foot care.Contribution: The study results will help improve nurses' awareness of the importance of diabetic foot care.

Diabetic Foot Ulcers in Geriatric Patients.

Care for the patient with diabetic foot ulcers (DFUs) entails understanding the epidemiology, pathophysiology, and a systematic approach to diagnosis and treatment. The authors will review elements of DFU in geriatric patients including the pathophysiology of diabetes, epidemiology and management of DFU in the context of developing a Plan for Healing. The authors will discuss comprehensive principles of a Plan for Healing, which applies to all aspects of chronic wounds.

Low-Level Laser Therapy (LLLT) for Diabetic Foot Ulcer in Uncontrolled Diabetes: A Case Report of Improved Wound Healing.

BACKGROUND Diabetes mellitus (DM) is one of the most prevalent diseases worldwide and is associated with increased morbidity and mortality. One of the microvascular complications of DM is diabetic foot ulcer (DFU), which is associated with increased mortality from serious infections and decreased functional capacity of the patient due to amputation. Uncontrolled diabetes is a significant risk factor for poor wound healing. There is a need for alternative treatments that can promote wound healing in these patients. Several studies have shown the effect of low-level laser therapy (LLLT) on wound healing in patients with DFU. LLLT is a potential therapeutic approach in patients with DFU. CASE REPORT A 55-year-old male patient presented with a history of DM, diabetic neuropathy, and diabetic foot. The patient had uncontrolled blood sugar levels, with an HbA1C of 9.3%. The patient received therapy in the form of wound care with normal saline, topical antibiotics, and LLLT, with a dose of 10 J/cm² with a frequency of therapy 3 times per week. After 12 weeks of therapy, there was improvement, characterized by wound tissue growth and no significant adverse effects during therapy. CONCLUSIONS LLLT can provide benefits in patients with DFU and uncontrolled diabetes. The wound showed improvement after 12 weeks of therapy, and there were no significant adverse effects during therapy. LLLT is a minimally invasive, easy-to-use, and inexpensive therapeutic option to induce wound healing in patients with DFU and uncontrolled diabetes.

Dehydrated Amnion Chorion Membrane versus standard of care for diabetic foot ulcers: a randomised controlled trial.

OBJECTIVE: Diabetic foot ulcers (DFUs) continue to challenge wound care practitioners. This prospective, multicentre, randomised controlled trial (RCT) evaluated the effectiveness of a dehydrated Amnion Chorion Membrane (dACM) (Organogenesis Inc., US) versus standard of care (SoC) alone in complex DFUs in a challenging patient population. METHOD: Subjects with a DFU extending into dermis, subcutaneous tissue, tendon, capsule, bone or joint were enrolled in a 12-week trial. They were allocated equally to two treatment groups: dACM (plus SoC); or SoC alone. The primary endpoint was frequency of wound closure determined by a Cox analysis that adjusted for duration and wound area. Kaplan-Meier analysis was used to determine median time to complete wound closure (CWC). RESULTS: The cohort comprised 218 patients, and these were split equally between the two treatment groups with 109 patients in each. A Cox analysis showed that the estimated frequency of wound closure for the dACM plus SoC group was statistically superior to the SoC alone group at week 4 (12% versus 8%), week 6 (22% versus 11%), week 8 (31% versus 21%), week 10 (42% versus 27%) and week 12 (50% versus 35%), respectively (p=0.04). The computed hazard ratio (1.48 (confidence interval: 0.95, 2.29) showed a 48% greater probability of wound closure in favour of the dACM group. Median time to wound closure for dACM-treated ulcers was 84 days compared to 'not achieved' in the SoC-treated group (i.e., ≥50% of SoC-treated DFUs failed to heal by week 12; p=0.04). CONCLUSION: In an adequately powered DFU RCT, dACM increased the frequency, decreased the median time, and improved the probability of CWC when compared with SoC alone. dACM demonstrated beneficial effects in DFUs in a complex patient population.

Analysis of factors influencing the recurrence of diabetic foot ulcers.

OBJECTIVE: The aim of this study is to investigate the factors influencing the recurrence of diabetic foot ulcers (DFU) and provide guidance for reducing the recurrence rate. METHODS: A total of 211 patients diagnosed with DFU who were hospitalized and discharged from the hospital from October 2015 to January 2020 were included as the study cohort. Participants were divided into two groups according to whether the foot ulcer recurred during the 2-year follow-up period: a recurrence group (n = 84) and a non-recurrence group (n = 127). The following data were collected and analyzed for the two groups of patients: general information, foot information, laboratory indicators, diabetes comorbidities, and complications. RESULTS: (1) The overall recurrence rate of diabetic foot ulcers (DFU) within 2 years was 39.8%, indicating a high recurrence rate. (2) Significant differences were observed between the two patient groups in terms of BMI, HbA1c, TBIL, CRP, financial situation, foot deformity, first ulcer on the sole of the foot, previous amputation history, Wagner grade of the first ulcer, osteomyelitis, DFU duration (>60 days), lower limb vascular reconstruction, peripheral arterial disease (PAD), and diabetic peripheral neuropathy (DPN) (t = 2.455; Z = -1.988, -3.731, -3.618; χ2 = 7.88, 5.004, 3.906, 17.178, 16.237, 5.007, 24.642, 4.782, 29.334, 10.253). No significant differences were found for the other indicators. (3) Logistic regression analysis revealed that TBIL (OR = 0.886, p = 0.036) was a protective factor against ulcer recurrence. In contrast, PAD, previous amputation history, DPN, and the first ulcer on the sole of the foot (OR = 3.987, 6.758, 4.681, 2.405; p < 0.05 or p < 0.01) were identified as risk factors for ulcer recurrence. CONCLUSION: Early screening and preventive education targeting high-risk factors such as DPN, PAD and the initial ulcer location on the sole of the foot are essential to mitigate the high long-term recurrence rate of DFU. Furthermore, the protective role of TBIL in preventing ulcer recurrence underscores the importance of monitoring bilirubin levels as part of a comprehensive management strategy for DFU patients.

Association of remoteness and ethnicity with major amputation following minor amputation to treat diabetes-related foot disease.

INTRODUCTION: Minor amputation is commonly needed to treat diabetes-related foot disease (DFD). Remoteness of residence is known to limit access to healthcare and has previously been associated with poor outcomes. The primary aim of this study was to examine the associations between ethnicity and remoteness of residency with the risk of major amputation and death following initial treatment of DFD by minor amputation. A secondary aim was to identify risk factors for major amputation and death following minor amputation to treat DFD. RESEARCH DESIGN AND METHODS: This was a retrospective analysis of data from patients who required a minor amputation to treat DFD between 2000 and 2019 at a regional tertiary hospital in Queensland, Australia. Baseline characteristics were collected together with remoteness of residence and ethnicity. Remoteness was classified according to the 2019 Modified Monash Model (MMM) system. Ethnicity was based on self-identification as an Aboriginal and Torres Strait Islander or non-Indigenous person. The outcomes of major amputation, repeat minor amputation and death were examined using Cox-proportional hazard analyses. RESULTS: A total of 534 participants were included, with 306 (57.3%) residing in metropolitan or regional centres, 228 (42.7%) in rural and remote communities and 144 (27.0%) were Aboriginal or Torres Strait Islander people. During a median (inter quartile range) follow-up of 4.0 (2.1-7.6) years, 103 participants (19.3%) had major amputation, 230 (43.1%) had repeat minor amputation and 250 (46.8%) died. The risks (hazard ratio [95% CI]) of major amputation and death were not significantly higher in participants residing in rural and remote areas (0.97, 0.67-1.47; and 0.98, 0.76-1.26) or in Aboriginal or Torres Strait Islander people (HR 1.44, 95% CI 0.96, 2.16 and HR 0.89, 95% CI 0.67, 1.18). Ischemic heart disease (IHD), peripheral artery disease (PAD), osteomyelitis and foot ulceration (p<0.001 in all instances) were independent risk factors for major amputation. CONCLUSION: Major amputation and death are common following minor amputation to treat DFD and people with IHD, PAD and osteomyelitis have an increased risk of major amputation. Aboriginal and Torres Strait Islander People and residents of remote areas were not at excess risk of major amputation.

Diabetic foot self-care knowledge and practice among patients with diabetes attending diabetic clinic in the Gambia.

Diabetic foot ulcer is the most common complication causing lots of admissions among diabetic patients. Understanding patients' level of foot self-care knowledge, practice and associated factors is important for planning interventions to control and prevent diabetic foot complications. This study aimed to assess the level of knowledge and practice of foot self-care among diabetic patients attending diabetic clinics in The Gambia. Two hundred and seventeen patients attending diabetic clinics in two public hospitals were selected using a successive sampling technique. Data were collected using a validated interviewer-administered questionnaire. Descriptive statistics were used to summarize the demographic and clinical data. Multivariate logistic regression was used to identify factors associated with foot self-care knowledge and practice. The findings showed a poor level of foot self-care knowledge (n = 114; 52.5%) and practice (n = 149; 68.7%). Patients' educational level was statistically significantly association with diabetic foot self-care knowledge (p = 0.02). Diabetic foot ulcer history (aOR = 0.23, 95% CI: 0.08-0.63; p < 0.001), diabetic hospitalization (aOR = 2.41, 95% CI: 1.23-4.75, p = 0.01) and diabetic foot care education (aOR = 2.65, 95% CI: 1.39-5.06, p < 0.001) were statistically significantly associated with foot self-care practice. The poor diabetic foot self-care knowledge and practice among these patients emphasize the need for a diabetic health education program in these clinics.

The interplay between patients and healthcare professionals in a cross-sectoral setting in connection with the treatment and care of patients with diabetic foot ulcers: a realistic evaluation.

BACKGROUND: Diabetes-related lower extremity complications such as diabetic foot ulcer (DFU) are a global disability burden. Treatment and care for patients with DFU call for a multisectoral approach that incorporates interdisciplinary care pathways. We aimed to explore the interplay between patients with DFU and healthcare professionals in cross-sectoral settings that address treatment and care and to determine "what works, for whom, and under what circumstances". METHOD: The study was designed as a realistic evaluation. The data were generated from September 2022 to March 2023 and drew upon approximately 60 h of participant observation of 14 patients during the treatment and care of DFUs in their homes (primary care) and/or at outpatient clinics (wound specialist clinics in a hospital setting) in a Danish cross-sectoral setting. The Standards for Reporting Qualitative Research (SRQR) were applied in this study. RESULTS: We identified three illuminating themes that described the interplay between patients with DFU and related healthcare professionals representing both primary and secondary health care systems: (1) humour is a relationship-enhancing element between nurses and patients; (2) support from patients' coping strategies promotes patient-centeredness and collaboration; and (3) patients and professionals occupy unnegotiated identity roles. CONCLUSION: Our study led to a refined programme theory developed through the realistic evaluation process that allows us to propose an answer to the problem of "what works, for whom, and under what circumstances". The interplay between patients with DFU and healthcare professionals in a cross-sectoral setting for treatment and care is characterised by the use of humour as a relation-enhancing element and by improving support for patient coping strategies, which encourages healthcare professionals to promote health literacy. Future research should examine strategies for negotiating identity roles between patients with DFU and healthcare professionals to enhance collaboration, patient health literacy, and health promotion in cross-sectoral healthcare settings.
