Portraying Diabetic Foot Ulcers: Comparative Evaluation of Diabetic Foot Infections versus Diabetic Foot Ulcers

Background: Confusion often arises in caring for diabetic foot infections and ulcers, especially with antimicrobials;we aim to shed light on this entity and alert healthcare workers to its stewardship. Methods: Records were reviewed between February 2016 and September 2023. Data for patients diagnosed with diabetes and foot ulcers, infected or not, were examined following ICD 9 search terms. Records for patients were included if they were prediabetic/diabetic adults with foot ulcers, more than 18 years old, and on antidiabetic treatment. Patients were excluded if they insulin resistant, with normal HgbA1c levels, wheel-chair dependent, bed-bound, non-diabetic patients, diabetic patients who had vascular lower limb surgery earlier to ulcers, diabetic patients who had aortocoronary bypass, deep venous thrombosis within six months, malignancy, and severe clinical depression. A modified IWGDF/IDSA guidelines definitions for DFI and DFU was considered. Statistical analysis was done using R programming. Statistical methods were employed as appropriate, and a significant P-value was considered for P Results: Most characteristics were well balanced between DFI and DFU, on imaging osteomyelitis and tissue swelling were significantly more in DFI. Endovascular radiological procedures showed angiograms to be considerably more in DFI, while angioplasty was more in DFU, in addition to smoking. Bacteremia was uncommon, and swab cultures were mostly polymicrobial in both ulcers;no clear association with blood bacteria was detected with the polymicrobial growth, though few were concordant. Antimicrobials prescribed for both ulcers were not statistically different except for carbapenems, which were more in DFI (P Conclusion: Attention should be paid to best practices while caring for diabetic ulcers. These include swab culture interpretations, the use of antimicrobials, and plan management according to DFI or DFU to utilize either local care or combination with antimicrobials.

Therapeutic Effectiveness of Leukocyte-and Platelet-rich Fibrin for Diabetic Foot Ulcers:A Retrospective Study

Objective Diabetic foot ulcer(DFU)is one of the most serious complications of diabetes.Leukocyte-and platelet-rich fibrin(L-PRF)is a second-generation autologous platelet-rich plasma.This study aims to investigate the clinical effects of L-PRF in patients with diabetes in real clinical practice.Methods Patients with DFU who received L-PRF treatment and standard of care(SOC)from 2018 to 2019 in Tongji Hospital were enrolled.The clinical information including patient characteristics,wound evaluation(area,severity,infection,blood supply),SOC of DFU,and images of ulcers was retrospectively extracted and analyzed.L-PRF treatment was performed every 7±2 days until the ulcer exhibited complete epithelialization or an overall percent volume reduction(PVR)greater than 80%.Therapeutic effectiveness,including overall PVR and the overall and weekly healing rates,was evaluated.Results Totally,26 patients with DFU were enrolled,and they had an ulcer duration of 47.0(35.0,72.3)days.The severity and infection of ulcers varied,as indicated by the Site,Ischemia,Neuropathy,Bacterial Infection,and Depth(SINBAD)scores of 2–6,Wagner grades of 1–4,and the Perfusion,Extent,Depth,Infection and Sensation(PEDIS)scores of 2–4.The initial ulcer volume before L-PRF treatment was 4.94(1.50,13.83)cm3,and the final ulcer volume was 0.35(0.03,1.76)cm3.The median number of L-PRF doses was 3(2,5).A total of 11 patients achieved complete epithelialization after the fifth week of treatment,and 19 patients achieved at least an 80%volume reduction after the seventh week.The overall wound-healing rate was 1.47(0.63,3.29)cm3/week,and the healing rate was faster in the first 2 weeks than in the remaining weeks.Concurrent treatment did not change the percentage of complete epithelialization or healing rate.Conclusion Adding L-PRF to SOC significantly improved wound healing in patients with DFU independent of the ankle brachial index,SINBAD score,or Wagner grade,indicating that this method is appropriate for DFU treatment under different clinical conditions.

Home-based Detection and Prediction of Diabetic Foot Ulcers at Early Stage Using Sensor Technology and Supervised Learning

For years,foot ulcers linked with diabetes mellitus and neuropathy have significantly impacted diabetic patients’ health-related quality of life(HRQoL). Diabetes foot ulcers impact15% of all diabetic patients at some point in their lives. The facilities and resources used for DFU detection and treatment are only available at hospitals and clinics,which results in the unavailability of feasible and timely detection at an early stage. This necessitates the development of an at-home DFU detection system that enables timely predictions and seamless communication with users,thereby preventing amputations due to neglect and severity. This paper proposes a feasible system consisting of three major modules:an IoT device that works to sense foot nodes to send vibrations onto a foot sole,a machine learning model based on supervised learning which predicts the level of severity of the DFU using four different classification techniques including XGBoost,K-SVM,Random Forest,and Decision tree,and a mobile application that acts as an interface between the sensors and the patient. Based on the severity levels,necessary steps for prevention,treatment,and medications are recommended via the application.

Global trends in publications regarding macrophages-related diabetic foot ulcers in the last two decades

BACKGROUND Diabetic foot ulcers(DFUs)are one of the most severe and popular complications of diabetes.The persistent non-healing of DFUs is the leading cause of amputation,which causes significant mental and financial stress to patients and their families.Macrophages are critical cells in wound healing and perform essential roles in all phases of wound healing.However,no studies have been carried out to systematically illustrate this area from a scientometric point of view.Although there have been some bibliometric studies on diabetes,reports focusing on the investigation of macrophages in DFUs are lacking.AIM To perform a bibliometric analysis to systematically assess the current state of research on macrophage-related DFUs.METHODS The publications of macrophage-related DFUs from January 1,2004,to December 31,2023,were retrieved from the Web of Science Core Collection on January 9,2024.Four different analytical tools:VOSviewer(v1.6.19),CiteSpace(v6.2.R4),HistCite(v12.03.07),and Excel 2021 were used for the scientometric research.RESULTS A total of 330 articles on macrophage-related DFUs were retrieved.The most published countries,institutions,journals,and authors in this field were China,Shanghai Jiao Tong University of China,Wound Repair and Regeneration,and Aristidis Veves.Through the analysis of keyword co-occurrence networks,historical direct citation networks,thematic maps,and trend topics maps,we synthesized the prevailing research hotspots and emerging trends in this field.CONCLUSION Our bibliometric analysis provides a comprehensive overview of macrophage-related DFUs research and insights into promising upcoming research.

Clinical comprehensive treatment protocol for managing diabetic foot ulcers:A retrospective cohort study

BACKGROUND Diabetic foot ulcers(DFUs)are a common complication of diabetes,often leading to severe infections,amputations,and reduced quality of life.The current standard treatment protocols for DFUs have limitations in promoting efficient wound healing and preventing complications.A comprehensive treatment approach targeting multiple aspects of wound care may offer improved outcomes for patients with DFUs.The hypothesis of this study is that a comprehensive treatment protocol for DFUs will result in faster wound healing,reduced amputation rates,and improved overall patient outcomes compared to standard treatment protocols.AIM To compare the efficacy and safety of a comprehensive treatment protocol for DFUs with those of the standard treatment protocol.METHODS This retrospective study included 62 patients with DFUs,enrolled between January 2022 and January 2024,randomly assigned to the experimental(n=32)or control(n=30)group.The experimental group received a comprehensive treatment comprising blood circulation improvement,debridement,vacuum sealing drainage,recombinant human epidermal growth factor and anti-inflammatory dressing,and skin grafting.The control group received standard treatment,which included wound cleaning and dressing,antibiotics administration,and surgical debridement or amputation,if necessary.Time taken to reduce the white blood cell count,number of dressing changes,wound healing rate and time,and amputation rate were assessed.RESULTS The experimental group exhibited significantly better outcomes than those of the control group in terms of the wound healing rate,wound healing time,and amputation rate.Additionally,the comprehensive treatment protocol was safe and well tolerated by the patients.CONCLUSION Comprehensive treatment for DFUs is more effective than standard treatment,promoting granulation tissue growth,shortening hospitalization time,reducing pain and amputation rate,improving wound healing,and enhancing quality of life.

Delayed treatment of diabetic foot ulcer in patients with type 2 diabetes and its prediction model

BACKGROUND Diabetic foot(DF)is a serious complication of type 2 diabetes.This study aimed to investigate the factors associated with DF occurrence and the role of delayed medical care in a cohort of patients with type 2 diabetes.AIM To reveal the impact of delayed medical treatment on the development of DF in patients with type 2 diabetes and to establish a predictive model for DF.METHODS In this retrospective cohort study,292 patients with type 2 diabetes who underwent examination at our hospital from January 2023 to December 2023 were selected and divided into the DF group(n=82,DF)and nondiabetic foot group(n=210,NDF).Differential and correlation analyses of demographic indicators,laboratory parameters,and delayed medical treatment were conducted for the two groups.Logistic regression was applied to determine influencing factors.Receiver operating characteristic(ROC)analysis was performed,and indicators with good predictive value were selected to establish a combined predictive model.RESULTS The DF group had significantly higher body mass index(BMI)(P<0.001),disease duration(P=0.012),plasma glucose levels(P<0.001),and HbA1c(P<0.001)than the NDF group.The NDF group had significantly higher Acute Thrombosis and Myocardial Infarction Health Service System(ATMHSS)scores(P<0.001)and a significantly lower delayed medical treatment rate(72.38%vs 13.41%,P<0.001).BMI,duration of diabetes,plasma glucose levels,HbA1c,diabetic peripheral neuropathy,and nephropathy were all positively correlated with DF occurrence.ATMHSS scores were negatively correlated with delayed time to seek medical treatment.The logistic regression model revealed that BMI,duration of diabetes,plasma glucose levels,HbA1c,presence of diabetic peripheral neuropathy and nephropathy,ATMHSS scores,and delayed time to seek medical treatment were influencing factors for DF.ROC analysis indicated that plasma glucose levels,HbA1c,and delayed medical treatment had good predictive value with an area under the curve of 0.933 for the combined predictive model.CONCLUSION Delayed medical treatment significantly affects the probability of DF occurrence in patients with diabetes.Plasma glucose levels,HbA1c levels,and the combined predictive model of delayed medical treatment demonstrate good predictive value.

Self-management in patients with diabetic foot ulcer:a concept analysis

Objective:This paper presents an analysis of the concept of patient outcomes.Methods:The present study conducted searches on various databases,including Wanfang,Sinomed,CNKI,Pub Med,Cochrane Library,Embase,Web of Science,and Ovid.The paper followed the Walker and Avant concept-analysis approach.Results:Initially,899 pieces of literature were identified through the search process,and after screening,41 of them were ultimately included in the analysis.The identified attributes of the concept included(1)capability,(2)decision making,and(3)action.These antecedents were shaped by factors such as illness perception,self-efficacy,and family and social.The consequences included(1)physiological effects,(2)psychological effects,and(3)social influence.Conclusions:The concept analysis of self-management in patients with diabetic foot ulcers(DFUs)not only aids in clinical practice and suppor ts interventions,but also contributes to the development of self-management theory.The common goal of clinical medical staff is to assist DFU patients in improving cognitive ability,making correct self-management decisions,and enhancing self-management behavior.

Impact of tibial transverse transport in tissue regeneration and wound healing with perspective on diabetic foot ulcers

In this editorial,we comment on an article by Liao et al published in the current issue of the World Journal of Diabetes.We focus on the clinical significance of tibial transverse transport(TTT)as an effective treatment for patients with diabetic foot ulcers(DFU).TTT has been associated with tissue regeneration,improved blood circulation,reduced amputation rates,and increased expression of early angiogenic factors.Mechanistically,TTT can influence macrophage polarization and growth factor upregulation.Despite this potential,the limitations and conflicting results of existing studies justify the need for further research into its optimal application and development.These clinical implications highlight the efficacy of TTT in recalcitrant DFU and provide lasting stimuli for tissue re-generation,and blood vessel and bone marrow improvement.Immunomodu-lation via systemic responses contributes to its therapeutic potential.Future studies should investigate the underlying molecular mechanisms to enhance our understanding and the efficacy of TTT.This manuscript emphasizes the potential of TTT in limb preservation and diabetic wound healing and suggests avenues for preventive measures against limb amputation in diabetes and peripheral artery disease.Here,we highlight the clinical significance of the TTT and its importance in healing DFU to promote the use of this technique in tissue regeneration.

Current scenario of traditional medicines in management of diabetic foot ulcers:A review

Diabetic foot infections and diabetic foot ulcers(DFU)cause significant suffering and are often recurring.DFU have three important pathogenic factors,namely,microangiopathy causing local tissue anoxia,neuropathy making the foot prone to injuries from trivial trauma,and local tissue hyperglycaemia favouring infection and delaying the wound healing.DFU have been the leading cause for non-traumatic amputations of part or whole of the limb.Western medicines focus mainly on euglycaemia,antimicrobials,debridement and wound cover with grafts,and off-loading techniques.Advances in euglycaemic control,foot care and footwear,systemic antimicrobial therapy,and overall health care access and delivery,have resulted in an overall decrease in amputations.However,the process of wound care after adequate debridement remains a major cost burden globally,especially in developing nations.This process revolves around two basic concerns regarding control/eradication of local infection and promotion of faster healing in a chronic DFU without recurrence.Wound modulation with various dressings and techniques are often a costly affair.Some aspects of the topical therapy with modern/Western medicines are frequently not addressed.Cost of and compliance to these therapies are important as both the wounds and their treatment are“chronic.”Naturally occurring agents/medications from traditional medicine systems have been used frequently in different cultures and nations,though without adequate clinical base/relevance.Traditional Chinese medicine involves restoring yin-yang balance,regulating the‘chi’,and promoting local blood circulation.Traditional medicines from India have been emphasizing on‘naturally’available products to control wound infection and promote all the aspects of wound healing.There is one more group of chemicals which are not pharmaceutical agents but can create acidic milieu in the wound to satisfy the above-mentioned basic concerns.Various natural and plant derived products(e.g.,honey,aloe vera,oils,and calendula)and maggots are also used for wound healing purposes.We believe that patients with a chronic wound are so tired physically,emotionally,and financially that they usually accept native traditional medicine which has the same cultural base,belief,and faith.Many of these products have never been tested in accordance to“evidence-based medicine.”There are usually case reports and experience-based reports about these products.Recently,there have been some trials(in vitro and in vivo)to verify the claims of usage of traditional medicines in management of DFU.Such studies show that these natural products enhance the healing process by controlling infection,stimulating granulation tissue,antimicrobial action,promoting fibroblastic activity and collagen deposition,etc.In this review,we attempt to study and analyse the available literature on results of topical traditional medicines,which are usually advocated in the management of DFU.An integrated and‘holistic’approach of both modern and traditional medicine may be more acceptable to the patient,cost effective,and easy to administer and monitor.This may also nevertheless lead to further improvement in quality of life and decrease in the rates of amputations for DFU.

Mesenchymal stem cells-based drug delivery systems for diabetic foot ulcer:A review

The complication of diabetes,which is known as diabetic foot ulcer(DFU),is a significant concern due to its association with high rates of disability and mortality.It not only severely affects patients’quality of life,but also imposes a substantial burden on the healthcare system.In spite of efforts made in clinical practice,treating DFU remains a challenging task.While mesenchymal stem cell(MSC)therapy has been extensively studied in treating DFU,the current efficacy of DFU healing using this method is still inadequate.However,in recent years,several MSCs-based drug delivery systems have emerged,which have shown to increase the efficacy of MSC therapy,especially in treating DFU.This review summarized the application of diverse MSCs-based drug delivery systems in treating DFU and suggested potential prospects for the future research.

Effect of Bismuth Subgallate/Borneol Combined with Autologous Platelet-Rich Gel in the Treatment of Patients with Diabetic Foot Ulcers

Objective: To explore the effect of Bismuth Subgallate/Borneol (SuileTM BSB) healing dressing combined with autologous platelet-rich gel (APG) in the treatment of diabetic foot ulcer (DFU). Methods: A total of 120 patients with DFU hospitalized in the Changsha Central Hospital from August 2020 to September 2021 were selected and randomly divided into an experimental group (BSB + APG, n = 60) and a control group (BSB, n = 60) according to random number table method. The total therapeutic effect, healing time, hospital stay, level indexes of various inflammatory factors before and after treatment and ulcer area were observed in the two groups. Results: The total effect of the control group was worse than that of the experimental group, and the data between the two groups were significant (P 0.05);after treatment, the levels of inflammatory factors including WBC, CRP, IL-6 and TNF-α in the control group were higher than those in the experimental group, and there was significant difference between the two groups (P 0.05);after 14 days of treatment, the ulcer area in the control group was larger than that in the experimental group, and the data between the two groups were significant (P Conclusion: BSB combined with APG can achieve better therapeutic effect, reduce the inflammatory reaction of patients, and promote wound healing in the treatment of patients with diabetic foot ulcer.

Future applications of exosomes delivering resolvins and cytokines in facilitating diabetic foot ulcer healing

Type 2 diabetes mellitus(T2DM)increases the risk of many lethal and debilitating conditions.Among them,foot ulceration due to neuropathy,vascular disease,or trauma affects the quality of life of millions in the United States and around the world.Physiological wound healing is stalled in the inflammatory phase by the chronicity of inflammation without proceeding to the resolution phase.Despite advanced treatment,diabetic foot ulcers(DFUs)are associated with a risk of amputation.Thus,there is a need for novel therapies to address chronic inflammation,decreased angiogenesis,and impaired granulation tissue formation contributing to the non-healing of DFUs.Studies have shown promising results with resolvins(Rv)and anti-inflammatory therapies that resolve inflammation and enhance tissue healing.But many of these studies have encountered difficulty in the delivery of Rv in terms of efficiency,tissue targetability,and immunogenicity.This review summarized the perspective of optimizing the therapeutic application of Rv and cytokines by pairing them with exosomes as a novel strategy for targeted tissue delivery to treat non-healing chronic DFUs.The articles discussing the T2DM disease state,current research on Rv for treating inflammation,the role of Rv in enhancing wound healing,and exosomes as a delivery vehicle were critically reviewed to find support for the proposition of using Rv and exosomes in combination for DFUs therapy.The literature reviewed suggests the beneficial role of Rv and exosomes and exosomes loaded with antiinflammatory agents as promising therapeutic agents in ulcer healing.

Adiponectin as a therapeutic target for diabetic foot ulcer

The global burden of diabetic foot ulcers(DFUs)is a significant public health concern,affecting millions of people worldwide.These wounds cause considerable suffering and have a high economic cost.Therefore,there is a need for effective strategies to prevent and treat DFUs.One promising therapeutic approach is the use of adiponectin,a hormone primarily produced and secreted by adipose tissue.Adiponectin has demonstrated anti-inflammatory and antiatherogenic properties,and researchers have suggested its potential therapeutic applications in the treatment of DFUs.Studies have indicated that adiponectin can inhibit the production of pro-inflammatory cytokines,increase the production of vascular endothelial growth factor,a key mediator of angiogenesis,and inhibit the activation of the intrinsic apoptotic pathway.Additionally,adiponectin has been found to possess antioxidant properties and impact glucose metabolism,the immune system,extracellular matrix remodeling,and nerve function.The objective of this review is to summarize the current state of research on the potential role of adiponectin in the treatment of DFUs and to identify areas where further research is needed in order to fully understand the effects of adiponectin on DFUs and to establish its safety and efficacy as a treatment for DFUs in the clinical setting.This will provide a deeper understanding of the underlying mechanisms of DFUs that can aid in the development of new and more effective treatment strategies.

Advances in the efficacy and safety of nano-silver dressings for diabetic foot ulcers(DFU)healing

As a new antimicrobial material,nano-silver dressing has been widely used in the treatment of diabetic foot ulcer(DFU)wounds in recent years.It not only has achieved a satisfactory effect in promoting the healing of DFU,but also has the advantages in controlling wound infection,relieving pain and reducing the frequency of dressing change.In this review,the principle,efficacy and safety of DFU wound healing were reviewed,and the future research directions were prospected.

Network pharmacology-based approach for exploring the biotargets and mechanisms of vitamin A for the treatment of diabetic foot ulcers

Background:In some developing countries,people have little knowledge about the causes of diabetic foot ulcers.Therefore,public health education for patients on these conditions is a prerequisite for effective pharmacological treatment.Diabetic foot ulcers are a complex symptom of diabetes and are hard to cure due to the lack of efficacious medicine and alternative treatment approaches.Vitamin A(VA)is known to have potent biological functions,including skin repair and immunoregulation.However,the potential pharmacological effects and molecular mechanisms of VA on foot ulcers are still to be discovered.Methods:By using bioinformatic/computational analyses,including network pharmacology,gene ontology and the Kyoto Encyclopedia of Genes and Genomes enrichment analysis,we aimed to identify and reveal the pharmacological targets,molecular mechanisms,biological functions,and signaling pathways of VA in the treatment of diabetic foot ulcers.Results:A total of 66 intersection genes were identified as candidate targets of VA,which are related to diabetic foot ulcers.Therein,18 core genes/targets,namely JUN,MAPK1,THRB,MAPK14,MTNR1B,CXCR3,ESR1,AR,HDAC1,IL-10,CNR1,DRD2,EGFR,ADRA2A,CCND1,RXRB,RARA,and RXRA,were further identified.Furthermore,the biological processes,cell components,and molecular functions which may underlie the effects of VA against diabetic foot ulcers were characterized.Conclusion:Based on our findings,we concluded that the pharmacological effects of VA on diabetic foot ulcers primarily involve the promotion of cellular regeneration and proliferation and the inhibition of inflammatory response.The core genes/targets may potentially serve as promising biomarkers for the diagnosis of diabetic foot ulcers.

Acknowledging the use of botanicals to treat diabetic foot ulcer during the 21st century:A systematic review

BACKGROUND Diabetic foot ulcer(DFU) is a serious health issue of diabetes mellitus that affects innumerable people worldwide. Management and treatment of this complication are challenging, especially for those whose immune system is weak.AIM To discuss the plants and their parts used to heal DFU, along with the mode of their administration in diabetic patients.METHODS The original articles on “the plants for the treatment of DFU” studied in clinical cases only were obtained from various bibliographic databases using different keywords.RESULTS The search resulted in 22 clinical cases records with 20 medicinal plants belonging to 17 families on 1553 subjects. The fruits and leaves were the most preferentially used parts for DFU treatment, regardless of whether they were being administered orally or applied topically. Of the 20 medicinal plants, 19 reported their effectiveness in increasing angiogenesis, epithelialization, and granulation, thus hastening the wound-healing process. The efficacy of these botanicals might be attributed to their major bioactive compounds, such as actinidin and ascorbic acid(in Actinidia deliciosa), 7-O-(β-D-glucopyranosyl)-galactin(in Ageratina pichinchensis), omega-3-fatty acid(in Linum usitatissimum), isoquercetin(in Melilotus officinalis), anthocyanins(in Myrtus communis), and plantamajoside(in Plantago major).CONCLUSION The validation of mechanisms of action underlying these phytocompounds contributing to the management of DFU can aid in our better understanding of creating efficient treatment options for DFU and its associated problems.

Efficacy of tibial transverse transport combined with platelet-rich plasma versus platelet-rich plasma alone in the treatment of diabetic foot ulcers:A meta-analysis

Background:Diabetic foot ulcers(DBFU)are one of the main complications of diabetes.Platelet-rich plasma(PRP)treatment is a commonly used treatment option.Tibial transverse transport(TTT)also has a therapeutic effect on DBFU.Some studies have found that the TTT combined with PRP(TTT&PRP)has a significant effect on DBFU.Methods:PubMed,Cochrane Library,Web of Science,EMBASE,Chinese Biomedical Literature,CNKI,VIP,and Wanfang databases were used to find literature on the treatment of DBFUs using the TTT and PRP treatment according to the inclusion criteria.The specific inclusion criteria are as follows:(1)research type:clinical controlled trials,including retrospective cohort and randomized controlled studies;(2)diagnosis of DBFUs that does not include a definitively diagnosed traumatic ulcer;(3)original materials of Chinese and English literature published in full text.The exclusion criteria are:(1)the research group was not defined or grouped;(2)nonrandomized controlled trials,non-cohort studies,non-case-control studies,retrospective studies,and case reports;(3)repetitive research and animal experimentation;(4)ulcers caused by other diseases;(5)conservative treatment or no use of invasive treatment methods.Review Manager software(version 5.3)was used to conduct a meta-analysis of the included results.Result:The literature included 6 randomized controlled studies,including 508 patients,254 patients in the PRP treatment group,and 254 patients in the TTT&PRP group.The meta-analysis results showed that in terms of treatment efficacy,the TTT&PRP combined treatment group had a higher efficacy than the PRP group.After treatment,the TTT&PRP group had better treatment effects in psychological function,physiological function,and social function compared to the PRP group.After treatment,the TTT&PRP group showed a significant increase in serum epidermal growth factor(EGF),vascular endothelial growth factor(VEGF),basic fibroblast growth factor(bFGF),and platelet-derived growth factor(PDGF)levels compared to the PRP group.In terms of wound healing after treatment,the TTT&PRP group performed better than the PRP group in terms of postoperative wound reduction rate,bacterial clearance rate,granulation tissue coverage rate,and granulation tissue growth thickness.Conclusion:TTT combined with PRP was more effective than PRP alone in treating DBFUs.

Effectiveness of topical oxygen therapy in wound healing for patients with diabetic foot ulcer

Objectives:Non-healing wounds have been one of the major challenges in health care because of increased morbidity,especially for those who have diabetes mellitus.Numerous regimens are being innovated to produce an evidence-based practice that would minimize complications and promote healing.Topical oxygen therapy is an innovation in wound care that has been considered influential in the wound healing process.This intervention aims to increase the oxygen concentration in the affected limb to promote wound healing.Methods:This research applied an experimental design that targeted a total of 60 adult patients aged 45–64 years with diabetic foot ulcers.A randomized systematic sampling technique was used to allow equal chances and prevent bias.In total,30 patients in the control group received usual care for diabetic foot ulcers,and the remaining 30 patients in the experimental group received topical oxygen therapy together with standard care for diabetic foot ulcers.Subjects were assessed using the Wagner-Meggitt Wound Classification System.Results:The result proved that there was a significant difference in the wound grade of patients in the experimental group after the application of the usual wound care plus the topical oxygen therapy using Friedman's test.The control and experimental groups were compared using Mann–Whitney statistical analyses,and the results showed that there was a significant difference between the control and experimental groups after the application of topical oxygen therapy.Conclusions:Topical oxygen therapy was demonstrated to be effective to aid in the wound healing process of patients with diabetic foot ulcers.Fur ther research was recommended to improve the application of topical oxygen therapy to patients with chronic wounds and promote the wound healing process.

Vitamin D deficiency among outpatients and hospitalized patients with diabetic foot ulcers:A systematic review and meta-analysis

BACKGROUND The definition of diabetic foot syndrome(DFS)varies depending on the location and resources.Few classifications are available according to the indication.DF ulcers and vitamin D deficiency are common diseases among patients with diabetes.Previous literature has shown an association between DF ulcer(DFU)and vitamin D deficiency.However,the available meta-0analysis was limited by substantial bias.AIM To investigate the association between DFUs and vitamin D levels.METHODS We searched PubMed,MEDLINE,and Cochrane Library,EBSCO,and Google Scholar for studies comparing vitamin D levels and DF.The keywords DFU,DFS,diabetic septic foot,vitamin D level,25-hydroxy vitamin D,vitamin D status,and vitamin D deficiency were used.The search engine was set for articles published during the period from inception to October 2022.A predetermined table was used to collect the study information.RESULTS Vitamin D level was lower among patients with DFU compared to their counterparts[odds ratio(OR):-5.77;95%confidence interval(CI):-7.87 to-3.66;χ2 was 84.62,mean difference,9;I2 for heterogeneity,89%;P<0.001 and P for overall effect<0.001].The results remained robust for hospitalized patients(OR:-6.3295%CI:-11.66 to-0.97;χ2 was 19.39;mean difference,2;I2 for heterogeneity,90%;P=0.02).CONCLUSION Vitamin D was lower among outpatients and hospitalized patients with DFUs.Further larger randomized controlled trials are needed.

A Case Report of Diabetic Foot Ulcer Treated by Herbal Food Homology Therapy

Diabetic foot ulcer (DFU) is a common and severe complication among patients with diabetes. There are hundreds of natural products derived from herbs that have been identified and proven to be effective for glucose-lowering and wound-healing effects, such as flavones. In this case study, we reported that a 76-year-old male patient with severe traumatic DFU was cured after drinking yellow tea (dehydrogenated Camellia sinensis) as a postprandial auxiliary treatment for six months. Previously, the patient was required to be hospitalized, but the wound deteriorated after five months. The patient drank yellow tea at approximately 12:30 pm (the active time of heart meridian) after lunch every day. Five grams of yellow tea were boiled in one liter of water and covered above 70°C for approximately 30 minutes. He experienced profuse sweating on his back after drinking yellow tea, with no other adverse effects. His lifestyle and healthcare remained constant except for replacing green tea with yellow tea. After six months, the ulcer had completely healed, and after one year of follow-up, no new abnormalities or side effects were found. This self-controlled case study indicates that flavone-enriched yellow tea or other herbs may be an auxiliary therapy for diabetes and its complications.
