Stem cell therapy in diabetic foot ulcer has emerged as a promising treatment option to promote ulcer healing. This network meta-analysis was undertaken to evaluate how they compete with each other and their ranking with respect to chances of ulcer healing. A systematic search strategy to retrieve data from five databases, were used to identify potential studies. Randomized controlled trial or clinical controlled trial, published in English, using any type of stem cells as intervention in individuals aged over 18 years diagnosed with diabetic foot ulcers were included. This network meta-analysis was performed using frequentist method using R version 4.2.1. Eighteen clinical trials were included in the study which included 13 interventions. The study found that most of the stem cells were significantly promoting ulcer healing chances with human viable wound matrix (hVWM) [RR 2.91; CI: 1.28, 6.64], peripheral blood mononuclear cells (PBMNC) [RR 2.35; CI: 1.21, 4.55], bone marrow mesenchymal stem cells (BMMSCs) [RR 2.20; CI: 1.34, 3.60], were top three stem cell options among all. P score also suggested the same. Risk of bias study suggested that there was "some concern or "high risk'' among majority of studies. It is evident from this study that bone marrow mononuclear cells were found to be most effective in wound healing in cases of diabetic foot ulcer in that order. Though there was no significant difference between these and more studies were required to ascertain whether they differ in term of efficacy for the clinical outcome of ulcer healing.

Background: Charcot foot or Charcot neuropathic joint disease (CN) is a rare and complex foot disease with unknown pathogenesis, hindering early identification and intervention. The study aimed to clarify the causal association between all predominant risk factors and CN.

Methods: Two-sample Mendelian Randomization (MR), Multivariate MR, and Bidirectional MR analyses investigated the causal association between 36 modifiable risk factors and CN. The causal relationship between CN and Inflammatory cytokine and immune cells was also analyzed.

Results: Genetic factors associated with obesity and genetic susceptibility to various autoimmune diseases and non-cancerous thyroid diseases increased the risk of CN (P < .05), genetically associated high basal metabolic rate and high total cholesterol decreased the risk of CN (P < .05). In addition, we found a bi-directional causal relationship between CN and diabetes. In further immune cell analysis, we found 8 CN related immune cells, and in inflammatory cytokine analysis, we found 2 CN related inflammatory cytokines.

Conclusions: This comprehensive MR Study supports the causal role of Obesity-related factors, diabetes, autoimmune-related factors, and smoking in the development and progression of CN. This study identifies a potential cause of CN that has not been identified in previous studies and provides a new direction for further research.

The aim of this narrative review was to discuss manifestations of endocrine disease other than diabetic foot in the lower extremities. Acromegaly, Addison's disease, Cushing's syndrome, hypo- and hyperthyroidism, hypo- and hyperparathyroidism, autoimmune polyglandular syndrome, hypopituitarism, and glucagonoma are among the endocrine diseases that may present with clinical manifestations in the lower extremities. Clinical signs vary depending on the underlying condition. Clinical suspicion is necessary for early diagnosis. Treatment of the underlying endocrine disease usually results in improvement of lower-extremity manifestations.

No consensus or guideline has been established regarding the optimal timing of tissue resection after revascularization in patients with chronic limb-threatening ischemia (CLTI). This study aimed to compare early tissue resection and watchful waiting after revascularization regarding the outcomes of patients with CLTI. We searched PubMed, the Cochrane Library, and EMBASE for relevant randomized trials and observational studies published from their inception to May 1, 2024. In total, five articles were analyzed. The results showed that the early tissue resection group had a higher wound healing rate than the watchful waiting group (I²= 26%, odds ratio [OR] = 2.80, 95% confidence interval [CI] 1.32 to 5.92, P = 0.007). However, the rate of major amputation was significantly higher in the early tissue resection group than in the watchful waiting group (I²= 5%, OR = 1.48, 95% CI 1.18 to 1.86, P < 0.001), and wound recurrence rate in the early tissue resection group was relatively higher than that in the watchful waiting group (I²= 0%, OR = 2.42, 95% CI: 0.99 to 5.93, P = 0.05). No statistical significance was found in the rate of postoperative mortality (I²= 2%, OR = 0.99, 95% CI: 0.69 to 1.41, P = 0.94) and wound healing time (I²= 97%, standardized mean difference = -105.92, 95% CI -232.96 to 21.13, P = 0.10) between the early tissue resection and watchful waiting groups. For patients without signs of infection, a watchful waiting strategy could reduce the risk of major amputation.

Objective: To explore the effect of information-motivation-behavioral skills model (IMB)-based continuous nursing model on the out-of-hospital rehabilitation of diabetic foot ulceration (DFU) patients, and to provide a theoretical basis for long-term disease management of DFU patients.

Methods: A total of 88 patients with DFU admitted to our Hospital were included in this prospective study. The patients were divided into control and study groups using the random number table method, with 44 cases in each group. Patients in the study group received both routine care and IMB-based continuing care, and the control group received only routine care.

Results: At week 1, FBS, PBG (2 h) and HbA1c were significantly decreased in the study group compared with that in the control group (P < .05). At week 3 and 6, blood glucose indicators were significantly improved in both groups compared with week 1 (P < .05). In additional, the number of non-infected patients at week 1 and week 3 in the study group was significantly higher than that in the control group (P < .05). At week 3, the number of cured patients was significantly higher in the study group than that in the control group (P < .05). And the area of ulcer healing in the study group was significantly larger than that in the control group at week 1 and week 3 (P < .05).

Conclusion: In conclusion, the continuous nursing mode based on IMB can help DFU patients manage blood glucose level, reduce wound infection, and accelerate wound healing, which is worthy of wide clinical application and promotion.

Correct classification of wounds is of paramount importance for diagnostic and therapeutic pathways. The aim of this study was to provide insight in the incidence of different aetiology of wounds and the healing time in a primary care setting. All patients with a wound presented in Primary Care (PC) practice from January 2017 through 2020 were included. A retrospective analysis related to age, sex, duration of wound healing, healing-rates, aetiology and comorbidity of the patients was performed. The prevalence of wounds in primary care was is 3.9 per 1000. In more than 90% of the wounds heal within 37 days. The wound healing speed and duration to closure differ significantly (P = .002) between aetiology. This study shows that 90% of wounds that enter a Dutch GP practice heal within 37 days. This study provides unique data on wound healing rates differentiated by etiology.

The objective of this study was to identify bone fractures and joint dislocations that have greater association with the severity of arch collapse in patients with Charcot foot involving the midfoot.A retrospective study in 28 (N = 29 feet) patients who had Charcot foot deformity of the midfoot. The study included stage III of Eichenholtz classification, and Schon classification types I to III. Talar-first metatarsal and calcaneal pitch angles and cuboid height were used to evaluate the severity of the midfoot deformity in a weightbearing lateral radiograph. Two investigators evaluated the bone fracture and joint dislocation involved in weightbearing antero-posterior and lateral radiographs.There were 13 (46%) feet that showed pattern 1, 9 (31%) feet with pattern 2, and 7 (25%) feet with pattern 3 according to the Schon classification. One foot had a combination of patterns 1 and 2. Midfoot ulceration occurred in 64% (n = 19) of feet. In the multivariate analysis, plantarflexion of talar-first metatarsal angle was predicted by navicular-medial cuneiform dislocation (p = .007 [-20.620-3.683]), an increase of the negative calcaneal pitch angle by fragmentation of the cuboid (p = .003 [-15.568-3.626]), and increment of the negative cuboid height by navicular-medial cuneiform and medial cuneiform-first metatarsal dislocations (p = .040 [-12.779-0.317], p = .002 [-13.437-3.267], respectively).Bone fractures and dislocations in the sagittal plane seem to contribute to midfoot collapse, but navicular-medial cuneiform dislocation/non-union and cuboid fragmentation predict severe rocker-bottom deformity in cases of Charcot foot.

Foot ulcerations are one of the most common complications of diabetes and one of the major initial causes of amputations. The formation of biofilms on wounds significantly contributes to infections and delayed healing. While existing methods for identifying these biofilms have limitations, there is a need for a convenient tool for its clinical application. This literature review aimed to address the problem with current clinical biofilm identification in wound care and a proposal for biofilm-detection-based wound care in diabetic foot ulcer patients. Identifying biofilms is particularly vital due to the absence of typical signs of infection in DFUs. However, current approaches, although effective, often prove invasive and technically intricate. The wound blotting technique, involving attaching a nitrocellulose membrane and subsequent staining, presents an alternative that is swift and non-invasive. Research highlights the applicability of wound blotting with alcian blue staining in clinical scenarios, consistently producing sensitive outcomes. By addressing the critical need for early biofilm detection, wound blotting holds promise for enhancing DFU management and contributing to strategies aimed at preventing amputations.

Objective: Diabetic foot ulcers are common chronic complications of diabetes mellitus that can lead to amputation and death in severe cases. There is limited research on the relationship between the red cell distribution width/albumin ratio and diabetic lower-extremity ulcers. The few studies that have been conducted have been in single-center inpatient settings and there is limited research in outpatient settings. This study investigated this relationship in adult outpatient clinics in the United States.

Methods: A retrospective cross-sectional study was conducted with 1624 participants of the National Health and Nutrition Examination Survey (NHANES) from 1999 to 2004. Three logistic regression models were developed to assess the association between red cell distribution width/albumin ratio and diabetic lower-extremity ulcers. The ratio was analyzed as a continuous and categorical variable. Stratified analyses were performed based on age, sex, HbA1c level, and body mass index.

Results: The study included 1624 adults, with a mean age of 65.0 ± 12.0 years, of whom 58.8% were male. The prevalence of diabetic lower-extremity ulcers was 8.0% (n = 131). Compared with individuals with a lower red cell distribution width/albumin ratio in T1(2.32,2.93), the adjusted OR values for the ratio and ulcers in T2(2.94,3.26), T3(3.27,7.42), and 2.07 (95% CI = 1.19∼3.61), 2.92 (95% CI = 1.63∼5.23). The association between the ratio and ulcers exhibited a non-linear relationship (nonlinear, P = .028).

Conclusion: These results support the hypothesis of an S-shaped relationship between red cell distribution width/albumin and diabetic lower-extremity ulcers. Monitoring the RDW/Albumin ratio could be crucial for preventing diabetic lower-extremity ulcers in outpatient settings. Regular assessments may help identify high-risk patients early, enabling timely interventions. Future studies should further assess these two factors and their underlying mechanisms.
