Abstract
Venous leg ulcers (VLUs) pose a growing healthcare challenge due to aging, obesity, and sedentary lifestyles. Despite various treatments available, addressing the complex nature of VLUs remains difficult. In this context, this study investigates repurposing boronated drugs to inhibit arginase 1 activity for VLU treatment. The molecular docking study conducted by Schrodinger GLIDE targeted the binuclear manganese cluster of arginase 1 enzyme (2PHO). Further, the ligand-protein complex was subjected to molecular dynamic studies at 500 ns in Gromacs-2019.4. Trajectory analysis was performed using the GROMACS simulation package of protein RMSD, RMSF, RG, SASA, and H-Bond. The docking study revealed intriguing results where the tavaborole showed a better docking score (-3.957 Kcal/mol) compared to the substrate L-arginine (-3.379 Kcal/mol) and standard L-norvaline (-3.141 Kcal/mol). Tavaborole interaction with aspartic acid ultimately suggests that the drug molecule binds to the catalytic site of arginase 1, potentially influencing the enzyme's function. The dynamics study revealed the compounds' stability and compactness of the protein throughout the simulation. The RMSD, RMSF, SASA, RG, inter and intra H-bond, PCA, FEL, and MMBSA studies affirmed the ligand-protein and protein complex flexibility, compactness, binding energy, van der waals energy, and solvation dynamics. These results revealed the stability and the interaction of the ligand with the catalytic site of arginase 1 enzyme, triggering the study towards the VLU treatment.

Patients with venous leg ulcers can be managed safely in the community ----results of an observational comparison study in Singapore. J Tissue Viability 2024:S0965-206X(24)00114-1. [PMID: 39164151 DOI: 10.1016/j.jtv.2024.07.009] [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: 10/13/2023] [Revised: 07/08/2024] [Accepted: 07/21/2024] [Indexed: 08/22/2024]
Abstract
AIM To examine the healing outcomes of patients with venous leg ulcers requiring compression bandaging in community care versus tertiary care. METHOD This was an analytical observational cohort study. Venous leg ulcer (VLU) patients who required compression bandaging were recruited from an outpatient vascular clinic between May 2021 and August 2022. Eligible patients received two-or four-layer compression bandaging and followed up with the community care or tertiary care centre nurses. The primary outcome was the difference in the total surface area of the VLU after 12 weeks, and the secondary outcome was the patient's quality of life, as measured by the Cardiff Wound Impact Schedule (CWIS). RESULTS Forty-seven VLU patients were recruited; 27 received compression bandaging in the community care and 20 by the tertiary care centre. Mean age 70 years old (SD 11.04). The two most prevalent comorbidities were hypertension (51.06 %) and diabetes mellitus (38.29 %). Among those who completed follow-up (12 weeks), the median difference of the total surface area of the VLU between community-based care (p = 0.02) versus tertiary-based care (0.003) was significant. However, there was no difference in the healing status between community and tertiary-based care (p = 0.68). There was no difference in the quality of life of patients between groups. CONCLUSION This first tropical study comparing VLU healing outcomes between community and tertiary care found no significant difference in healing with compression bandaging by nurses in either setting. However, the small sample size and high dropout rate limit the generalizability of the findings, necessitating a larger-scale study with longer follow-up. Despite these limitations, the study is a crucial step toward improving wound care services in Singapore, and highlights the need for further research to guide future community wound care implementation.

Abstract
Venous leg ulcers (VLUs) are hard-to-heal wounds and are prone to microbial colonization. Innovative and improved therapies are thus required to resolve local infection and enhance the wound healing process. The objective of this study was to evaluate the effectiveness of medical-grade honey (MGH) for the treatment of clinically infected and non-healing VLUs. This prospective case series included nine patients with an average age of 83.4 years (range: 75-91 years) with a total of eleven VLUs, previously ineffectively treated with various products. Major risk factors for the appearance of VLUs were chronic venous insufficiency, advanced age, multiple comorbidities (particularly cardiovascular diseases), and impaired mobility. All wounds presented with local signs of infection. Upon presentation, treatment was commenced with a range of MGH-based products (L-Mesitran®). Clinical signs of infection were eliminated by MGH after 2.2 weeks on average (range: 1-4 weeks), and wounds were completely healed after 7 weeks on average (range: 3-18 weeks). No further complications or recurrences were observed. MGH has a broad-spectrum antimicrobial activity and promotes rapid healing, thus improving patients' quality of life. Moreover, MGH-based products are safe, easy to use, cost-effective, and can effectively treat VLUs alone or in combination with standard-of-care therapies.

Abstract
BACKGROUND Recanalization of target veins after treatment of superficial venous incompetence has clinical implications and may depend on the type of intervention. The aim of this study was to evaluate patient and procedural factors associated with truncal vein recanalization in a large study cohort using the Vascular Quality Initiative (VQI) Varicose Vein Registry. METHODS We performed a retrospective review using the VQI Varicose Vein Registry from 2014 to 2018. We evaluated all procedures performed for truncal venous insufficiency. Demographic data and information about treatment modality were collected. Patients were separated into recanalization and nonrecanalization groups based on the status of the treated vein at follow-up ultrasound examination. The vein was only considered recanalized if the VQI noted complete recanalization of the target vein. Univariate and multivariate comparisons were performed as appropriate. RESULTS A total of 10,604 procedures were performed in 7403 patients. The average age was 55.9 years and 70.3% of the patients were female. Patients with recanalization were more likely to have a history of phlebitis (P < .001) and had a higher mean body mass index (30.5 vs 32., kg/m2 ; P = .006) compared with those without recanalization. There was no difference in the use of compression therapy, anticoagulation, deep venous reflux, number of pregnancies, prior deep vein thrombosis, Venous Clinical Severity Score, and clinical-etiology-anatomy-pathophysiology between patients with and without recanalization. The number of truncal veins treated per procedure was higher in the recanalization group compared with the nonrecanalization group (2.36 vs 1.88; P = .001). After multivariate logistic regression, laser ablation was associated with higher rate of recanalization compared with radiofrequency ablation (P = .017). CONCLUSIONS This study is the first to use VQI based data to describe risk factors for recanalization following treatment of truncal venous reflux. The use of laser ablation for truncal veins is associated with a higher risk for recanalization compared with radiofrequency ablation. Obesity, prior phlebitis, and number of veins treated were independently associated with increased rate of recanalization.

Abstract
OBJECTIVE To examine the correlation between ABO blood type and the incidence of lower extremity deep vein thrombosis (LEDVT) in elderly patients after hip fracture surgery, while identifying contributing factors to thrombogenesis. METHODS We conducted a retrospective analysis of 159 elderly patients with hip fractures treated at Tianjin Hospital (Affiliated Hospital of Tianjin University) from December 2021 to December 2023. The cohort was divided into two groups: those with O blood type (45 patients) and those with non-O blood types (114 patients). We analyzed clinical data and the incidence of LEDVT between the groups. Logistic regression was used to identify independent risk factors for LEDVT, and receiver operator characteristic (ROC) curve analysis evaluated the predictive efficacy of these factors. RESULTS The incidence of LEDVT was significantly higher in the non-O blood type group compared to the O blood type group (34.21% vs. 15.56%, P = 0.0408). Logistic regression identified high body mass index (BMI), comorbid hypertension, low platelet count (PLT), prolonged prothrombin time (PT), and non-O blood type as independent risk factors for LEDVT. The ROC curve for these predictors showed an area under the curve of 0.862, with a sensitivity of 75.22%, a specificity of 86.96%, and an accuracy of 78.62%. CONCLUSION ABO blood type is correlated with the occurrence of LEDVT in elderly patients' post-hip fracture. Those with non-O blood type, alongside other factors such as high BMI, hypertension, low PLT, and extended PT, are at increased risk of developing LEDVT.

Abstract
OBJECTIVE To evaluate the short-term clinical outcomes of radiofrequency ablation (RFA) using a radiofrequency (RF) needle device for varicose ulcers. METHODS From September 2020 to September 2021, a total of 80 patients with varicose ulcers were included in this study. Based on the different surgical methods, the patients were divided into RF group and control groups, with 40 cases in each group. In the RF group, RFA was performed using an RF needle device and foam sclerotherapy was used for superficial veins. The control group was treated with conventional high-ligation stripping. The surgical data, hospitalization data, clinical efficacy, and postoperative complications of two groups were compared. Meanwhile, the correlation between RBC, HB, HCT, and ulcer healing time was analyzed. RESULTS Compared to the control group, RF group had shorter surgery time, duration in the hospital, and less intraoperative bleeding (p < .05). The VCSS and CIVIQ scores in RF group were significantly higher than that in control group (p < .05). The healing time of ulcers was shorter in the RF group (x2 = 19.766, p = .000). The RF group had fewer postoperative complications. There was a positive correlation between RBC, HB, and HCT, and ulcer healing time (p < .05). CONCLUSION The use of the RF needle device for RFA to treat patients with varicose ulcers showed acceptable short-term clinical outcomes with less incidence of trauma, faster recovery, and fewer complications.

Abstract
AIM To compare the ablation techniques' efficacy of endovenous microwave ablation (EMA) combined with high ligation (HL), foam sclerotherapy (FS) and compression therapy (CT) and endovenous laser ablation (EVLA) combined with HL-FS-CT in the treatment of VLUs. METHOD 301 consecutive patients with VLUs from 2013 to 2022 in a 3200-bed hospital were intervened by EMA combined with HL-FS-CT and EVLA combined with HL-FS-CT were retrospectively compared. RESULTS One hundred thirty-four patients underwent EMA+HL-FS-CT and 167 patients underwent EVLA+HL-FS-CT. The primary outcome of the ulcer healing time was 1.45(0.75-1.5) months and 1.86(0.5-2.5) months, respectively, in the two groups (HR for ulcer healing was 1.26, 95% CI [0.96-1.66], p = 0.097). Secondary outcomes included that no significant difference was found in ulcer recurrence and GSV recanalization and complications between the two groups, and the postoperative VCSS and AVVQ were significantly lower than the baseline values in the respective groups (p = 0.0001). CONCLUSION EMA+HL-FS-CT and EVLA+HL-FS-CT are both effective at treating VLUs. Both of the two comprehensive treatments were beneficial to the healing of ulcers, but no evidence showed which one was superior in the ulcer healing time.

Abstract
AIM To investigate the differences in utility between conventional dressings and hydrogel dressings for the treatment of diabetic foot ulcer (DFU). METHODS The PubMed, Embase, Cochrane Library, CNKI, VIP and Wanfang databases were systematically searched up to 21 January 2023. Fixed/random-effect models were used to calculate the odds ratios (ORs) and mean differences (MDs) with 95% confidence intervals (CIs) for the effect size analysis, with heterogeneity determined by I2 statistics. Subgroup analyses of different classes of hydrogel were also conducted. RESULTS A total of 15 randomized controlled trials with 872 patients were eligible for the present analysis. Compared with conventional dressings, hydrogel dressings significantly improved the healing rate (OR 4.09, 95% CI 2.83 to 5.91), shortened the healing time (MD -11.38, 95% CI -13.11 to -9.66), enhanced granulation formation (MD -3.60, 95% CI -4.21 to -3.00) and epithelial formation (MD -2.82, 95% CI -3.19 to -2.46), and reduced the incidence of bacterial infection (OR 0.10, 95% CI 0.05 to 0.18). CONCLUSION The meta-analysis showed that hydrogel dressings are more effective in treating DFU compared with conventional dressings.

Abstract
Venous stasis ulcers are nonhealing lesions due to venous hypertension secondary to valvular dysfunction or deep venous outflow obstruction. We describe a case of a 71-year-old male with a history of polycythemia vera, secondary myelofibrosis, and massive splenomegaly up to 38 cm who presented with chronic, perimalleolar venous stasis ulcers and pain on the left lower extremity. CT showed significant compression of the left common iliac vein due to mass effect from the spleen. He was managed medically while being evaluated for partial splenic artery embolization but expired due to other chronic conditions before any intervention could be performed. Partial splenic artery embolization may be considered as a treatment option for patients with symptomatic iliac vein compression due to massive splenomegaly secondary to myelofibrosis, as long as extramedullary hematopoiesis is not compromised.

Abstract
OBJECTIVE The aim of this case series is to present an alternative approach to managing post-Mohs Micrographic Surgery (Mohs) wounds with hypothermically stored amniotic membrane (HSAM). METHOD A case series of patients with post-Mohs wounds is presented, with four patients referred for hard-to-heal wounds following a Mohs procedure that was performed 1-3 months previously. All wounds underwent weekly assessment, debridement, and application of HSAM and secondary dressings. Treatment also included management of bioburden, proper skin care and compression therapy for lower extremity wounds. RESULTS This case series of seven wounds consisted of four females and three males with a mean age of 87.6 years. Mean wound size at first application of HSAM was 1.34±1.20cm2. All wounds closed, with an average time to wound closure of 43.7±27.1 days. Patients received an average of 4.6±2.5 HSAM applications. The four post-Mohs wounds with a history of being hard-to-heal had an average time to wound closure of 35.5±16.3 days, with an average duration of 86.5±32.4 days prior to the first HSAM application. CONCLUSION The results of this case series suggest that use of HSAM may provide an alternative approach to managing post-Mohs wounds. In addition, these findings suggest that HSAM may be of greatest benefit when applied early after Mohs surgery.

Abstract
OBJECTIVE This study described the experiences and perceptions of how primary health care professionals (PHCPs) support patients with venous leg ulcers (VLUs) in self-care monitoring. DESIGN A qualitative approach with reflexive thematic analysis was used, with 24 individual qualitative open interviews. SETTING Primary health care clinics and community health care in four southern regions in Sweden. SUBJECTS Registered nurses, district nurses and nurse assistants who had experience of caring for patients with VLUs. In total, 24 interviews were conducted with PHCPs in Sweden. RESULTS PHCPs have a vital role in promoting patient independence and responsibility, identifying needs and adapting care strategies, while also recognising unmet needs in patients with VLUs. CONCLUSION PHCPs actively monitor patients' self-care and establish caring relationships. They see a need for a structured primary health care work routine for ulcer management.

Abstract
The pathogenesis of chronic wounds (CW) involves a multifaceted interplay of biochemical, immunological, hematological, and microbiological interactions. Biofilm development is a significant virulence trait which enhances microbial survival and pathogenicity and has various implications on the development and management of CW. Biofilms induce a prolonged suboptimal inflammation in the wound microenvironment, associated with delayed healing. The composition of wound fluid (WF) adds more complexity to the subject, with proven pro-inflammatory properties and an intricate crosstalk among cytokines, chemokines, microRNAs, proteases, growth factors, and ECM components. One approach to achieve information on the mechanisms of disease progression and therapeutic response is the use of multiple high-throughput 'OMIC' modalities (genomic, proteomic, lipidomic, metabolomic assays), facilitating the discovery of potential biomarkers for wound healing, which may represent a breakthrough in this field and a major help in addressing delayed wound healing. In this review article, we aim to summarize the current progress achieved in host-microbiome crosstalk in the spectrum of CW healing and highlight future innovative strategies to boost the host immune response against infections, focusing on the interaction between pathogens and their hosts (for instance, by harnessing microorganisms like probiotics), which may serve as the prospective advancement of vaccines and treatments against infections.

Abstract
BACKGROUND Pinch grafting has experienced a resurgence in interest in recent years, stemming from its simplicity, safety, and potential in restoring tissue integrity. While historically employed for chronic nonhealing wounds, pinch grafts have shown promise following surgical procedures, particularly those involving the lower extremities. OBJECTIVE To systematically review the literature and present an updated overview of the current applications of pinch grafting. METHODS A systematic review was conducted according to the Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines. In collaboration with a medical reference librarian, the PubMed, Embase, Scopus, and Web of Science databases were searched for studies reporting on the use of pinch grafting from 2000 onward. The references of each included article were also screened. RESULTS Ten articles met final inclusion criteria. In total, 300 patients underwent pinch grafting for treatment of skin ulceration, while an additional 35 cases were performed as an alternative to primary closure following skin cancer resection. Overall, pinch grafting was safe and well tolerated, with minimal adverse outcomes reported. CONCLUSION Pinch grafting is a safe, straightforward, and effective technique to promote the healing of chronic wounds. While the procedure shows early promise in emerging applications within dermatologic surgery, only about 10% of the reported cases involved this indication, reflecting a need for further research in this area.

Abstract
This study aims to evaluate the effects of electromagnetic therapy (EMT) on the treatment of venous leg ulcers (VLUs) by synthesising and appraising available meta-analyses (MAs) and systematic reviews (SRs). A comprehensive literature search was conducted across major databases up to 10 January 2024, focusing on SRs/MAs that investigated the use of EMT for VLUs. Selection criteria followed the PICO framework, and dual-author extraction was used for accuracy. Quality assessment tools included AMSTAR2, ROBIS, PRISMA, and GRADE. The search yielded five eligible studies. The reviews collectively presented moderate methodological quality and a low risk of bias in several domains. Reporting quality was high, albeit with inconsistencies in fulfilling certain PRISMA checklist items. The evidence quality, primarily downgraded due to small sample sizes, was rated as moderate. Whilst some studies suggest potential benefits of EMT in the treatment of VLUs, the overall evidence is inconclusive due to methodological limitations and limited sample sizes. This review underscores the need for future research with more rigorous methodologies and larger cohorts to provide clearer insights into the efficacy of EMT for VLUs.

Abstract
PURPOSE Venous leg ulcers are chronic wounds that are difficult to cure. The aim of the study was to compare the therapeutic efficacy of two methods of physical medicine - magneto-LED therapy and magnetostimulation, applied as adjuvant treatment in the treatment of venous leg ulcers. METHODS The study included 81 patients, 37 male (45.6%) and 44 female (54.3%) ones, age range between 45 and 90 years, with venous leg ulcers. The patients were assigned to two study groups: magneto-LED therapy (group 1) or magnetostimulation (group 2). In both groups, a total of 40 daily procedures were performed. Wound healing was evaluated using computerized planimetry and the pain intensity on numeric rating scale. RESULTS After treatment, the decrease in healing rate in group 1 was statistically significantly higher in comparison to group 2 (p < 0.001), while a statistically significant reduction in the surface area of ulcers was obtained, amounting on the average from 6.34 ± 1.29 cm2 to 2.31 ± 1.25 cm2 in group 1 (p < 0.001), and from 6.52 ± 1.20 cm2 to 4.79 ± 1.17 cm2 in group 2 (p < 0.001). The percentage changes of ulcers area in group 1 (64.21 ± 17.94%) were statistically significantly greater as compared to group 2 (25.87 ± 14.07%) (p < 0.001). After treatment, the decrease in pain relief in group 1 was statistically significantly higher in comparison to group 2 (p = 0.006), while pain intensity after treatment decreased statistically significantly in both compared groups of patients (p < 0.001). CONCLUSIONS Magneto-LED therapy and magnetostimulation caused significant reduction of surface area of the treated venous leg ulcers and pain intensity, yet magneto-LED therapy was more efficient. Both evaluated methods also significantly reduced pain intensity.

Abstract
Innate immunity has considerable specificity and can discriminate between individual species of microbes. In this regard, pathogens are "seen" as dangerous to the host and elicit an inflammatory response capable of destroying the microbes. This immune discrimination is achieved by toll-like receptors on host cells recognizing pathogens, such as Staphylococcus aureus, and microbe-specific pathogen-associated molecular pattern (PAMP) molecules, such as lipoteichoic acid (LTA). PAMPs impede wound healing by lengthening the inflammatory phase of healing and contributing to the development of chronic wounds. Preventing PAMPs from triggering the release of inflammatory cytokines will counteract the dysregulation of inflammation. Here, we use ELISA to evaluate the use of cationic molecules branched polyethylenimine (BPEI), PEGylated BPEI (PEG-BPEI), and polymyxin-B to neutralize anionic LTA and lower levels of TNF-α cytokine release from human THP-1 monocytes in a concentration-dependent manner. Additional data collected with qPCR shows that BPEI and PEG-BPEI reduce the expression profile of the TNF-α gene. Similar effects are observed for the neutralization of whole-cell S. aureus bacteria. In vitro cytotoxicity data demonstrate that PEGylation lowers the toxicity of PEG-BPEI (IC50 = 2661 μm) compared to BPEI (IC50 = 853 μM) and that both compounds are orders of magnitude less toxic than the cationic antibiotic polymyxin-B (IC50 = 79 μM). Additionally, the LTA neutralization ability of polymyxin-B is less effective than BPEI or PEG-BPEI. These properties of BPEI and PEG-BPEI expand their utility beyond disabling antibiotic resistance mechanisms and disrupting S. aureus biofilms, providing additional justification for developing these agents as wound healing therapeutics. The multiple mechanisms of action for BPEI and PEG-BPEI are superior to current wound treatment strategies that have a single modality.

Abstract
A case series of the use of amniotic membrane (AM) for treating chronic nonhealing wounds. It presents five cases of polymorbid patients with a total of nine chronic nonhealing wounds. The patient group consisted of four men and one woman with various comorbidities, aged 45-72 years. The mean initial wound size was 15.8 cm2, and the mean time from the onset of the wound to the first application of AM was 122 weeks. The wounds were caused by chronic venous insufficiency and/or peripheral arterial disease. Wounds were treated in a standardized protocol. AM was applied weekly in the first month and then every two weeks. Photo documentation of the wound and microbiological colonization was carried out at each visit. In three out of five patients, the AM treatment effectively promoted healing up to complete wound closure. In two cases, the wounds stayed unhealed despite numerous AM applications. Pain relief was noted in all patients. The success of the treatment was closely tied to patient factors, such as adherence to the prescribed treatment regimen and individual patient characteristics. In some cases, treatment failure was observed, possibly due to underlying comorbidities, wound parameters, or poor patient compliance. AM treatment has the potential to become a viable treatment option for these nonhealing wounds. However, the effectiveness of the treatment may be influenced by various patient factors and the underlying cause of the wound. Therefore, it is crucial to have an individualized treatment plan that considers these particular factors.

Abstract
BACKGROUND The American Heart Association (AHA), in conjunction with the National Institutes of Health, annually reports the most up-to-date statistics related to heart disease, stroke, and cardiovascular risk factors, including core health behaviors (smoking, physical activity, nutrition, sleep, and obesity) and health factors (cholesterol, blood pressure, glucose control, and metabolic syndrome) that contribute to cardiovascular health. The AHA Heart Disease and Stroke Statistical Update presents the latest data on a range of major clinical heart and circulatory disease conditions (including stroke, brain health, complications of pregnancy, kidney disease, congenital heart disease, rhythm disorders, sudden cardiac arrest, subclinical atherosclerosis, coronary heart disease, cardiomyopathy, heart failure, valvular disease, venous thromboembolism, and peripheral artery disease) and the associated outcomes (including quality of care, procedures, and economic costs). METHODS The AHA, through its Epidemiology and Prevention Statistics Committee, continuously monitors and evaluates sources of data on heart disease and stroke in the United States and globally to provide the most current information available in the annual Statistical Update with review of published literature through the year before writing. The 2024 AHA Statistical Update is the product of a full year's worth of effort in 2023 by dedicated volunteer clinicians and scientists, committed government professionals, and AHA staff members. The AHA strives to further understand and help heal health problems inflicted by structural racism, a public health crisis that can significantly damage physical and mental health and perpetuate disparities in access to health care, education, income, housing, and several other factors vital to healthy lives. This year's edition includes additional global data, as well as data on the monitoring and benefits of cardiovascular health in the population, with an enhanced focus on health equity across several key domains. RESULTS Each of the chapters in the Statistical Update focuses on a different topic related to heart disease and stroke statistics. CONCLUSIONS The Statistical Update represents a critical resource for the lay public, policymakers, media professionals, clinicians, health care administrators, researchers, health advocates, and others seeking the best available data on these factors and conditions.

Abstract
BACKGROUND Skin grafting is a helpful instrument in a plastic surgeon's arsenal. Several types of dressings were designed to facilitate the process of graft integration. Negative-pressure wound therapy is a proven dressing method, enhancing graft survival through several mechanisms: aspiration of secretions, stimulation of neoangiogenesis, and promotion of an anti-inflammatory environment. Silver nanoparticle dressings also bring multiple benefits by bearing an antimicrobial effect and providing a humid medium, which are favorable for epithelialization. The combination of NPWT (negative-pressure wound therapy) with AgNPs (silver nanoparticles) has not been widely studied. MATERIALS AND METHODS This study aimed to compare the outcomes of silver nanoparticle sheets with the combination of negative-pressure wound therapy and silver nanoparticle dressings. We conducted a comparative prospective study on 80 patients admitted to the Plastic Surgery Department of "Prof. Dr. Agrippa Ionescu" Emergency Clinical Hospital between 1st of January 2020 and 31st of December 2022. The study population was randomized to receive either silver nanoparticle dressings or negative-pressure wound therapy (NPWT) combined with silver nanoparticle dressings. Various parameters were monitored, including patient comorbidities and graft-related data such as defect etiology, graft integration, and graft size. Dressings were changed, and graft status was evaluated at 7, 10, and 14 days postoperatively. Additionally, baseline C-reactive protein (CRP) levels were measured before surgery and 7, 10, and 14 days postoperatively. RESULTS The study demonstrated an enhanced integration of skin grafts at all evaluation stages when employing NPWT combined with AgNPs, particularly evident 10 days post operation. Significant variations in graft integration were also observed based on factors such as diabetes, cardiovascular disease, graft size, or the origin of the grafted defect. Moreover, dynamic C-reactive protein monitoring showed a statistically significant decrease in CRP levels 10 days post operation among patients treated with NPWT in conjunction with silver dressing, consistent with the nearly complete integration of skin grafts at this evaluation threshold. CONCLUSION Several factors influence the postoperative evolution of split-skin grafts. Postoperative dressings target local factors to enhance graft integration further. Our research demonstrated that the innovative combination of NPWT-assisted dressings, complemented by a silver nanoparticle sheet, resulted in improved benefits for graft integration and the alleviation of systemic inflammation.

Abstract
This study aimed to investigate the causal relationship between inflammatory cytokines and the risk of varicose veins. The data were sourced from genome-wide association studies (GWAS) of European individuals. Multiple Mendelian randomization (MR) methods were used to evaluate the association between inflammatory cytokines and varicose veins. The study found significant associations between elevated levels of certain inflammatory biomarkers (e.g., CASP-8, Vascular endothelial growth factor A levels (VEGF_A)) and an increased risk of varicose veins, while others (e.g., 4EBP1, MMP-10) showed a protective effect. The MR-Egger Intercept and heterogeneity tests indicated no significant pleiotropy or heterogeneity. This comprehensive MR analysis identifies several cytokines as potential contributors to the pathogenesis of varicose veins, offering insights into novel therapeutic targets. Our findings underscore the importance of inflammation in varicose veins and suggest that targeting specific cytokines could be a promising strategy for the treatment and prevention of varicose veins.

Abstract
BACKGROUND Venous leg ulcers take time to heal. It is advocated that physical activity plays a role in healing, and so does the patient's nutritional status. Additionally, malnutrition influences the inflammatory processes, which extends the healing time. Therefore, the staff's advising role is important for patient outcomes. Thus, this study aimed to investigate the associations between given self-care advice and healing time in patients with venous leg ulcers while controlling for demographic and ulcer-related factors. METHODS The sample consisted of patients registered in the Registry of Ulcer Treatment (RUT) which includes patient and ulcer-related and healing variables. The data was analyzed with descriptive statistics. Logistic regression models were performed to investigate the influence of self-care advice on healing time. RESULTS No associations between shorter healing time (less than 70 days) and the staff´s self-care advice on physical activity was identified, whilst pain (OR 1.90, CI 1.32-2.42, p < 0.001) and giving of nutrition advice (OR 1.55, CI 1.12-2.15, p = 0.009) showed an association with longer healing time. CONCLUSIONS Neither self-care advice on nutrition and/or physical activity indicated to have a positive association with shorter healing time. However, information and counseling might not be enough. We emphasize the importance of continuously and systematically following up given advice throughout ulcer management, not only when having complicated ulcers.

Abstract
INTRODUCTION The sural neuro-fasciocutaneous flap is widely used for reconstructing skin defects in the lower calf. Variations of the sural nerve in the calf are infrequent, which may require a variation in the traditional surgical procedure. CASE PRESENTATION A 76-year-old male patient had soft tissue defect of the right lateral ankle and lower leg caused by an accident 18 years ago. He had exposed bones and had osteomyelitis. He underwent two primary operations, and finally, we used a sural neuro-fasciocutaneous flap to effectively cover the defect. We observed that the course of the sural nerve was atypical during the surgery, and we adjusted the flap axis laterally to bring the lateral sural cutaneous nerve inside the flap to improve the success rate of the surgery. The flap entirely survived, and there was no sensory impairment in the calf. The patient was discharged from the hospital after 10 days. CLINICAL DISCUSSION Some type of variant of the sural nerve makes the flap harvest without the neurovascular component of the sural nerve and the cutaneous chain, which might decrease flap survival. Moving the flap axis laterally and bringing in the lateral sural nerve or peroneal communicating nerve offers an adequate blood supply to the vascular territory and the flap region. CONCLUSION In patients with sural nerve variants, the procedure does not have to follow the traditional theory of the sural neuro-fasciocutaneous flap. Preoperative and intraoperative protection of the sural nerve variant should also be considered.

Abstract
Varicose veins (VVs) have a high prevalence worldwide and have become a major medical burden. Their pathophysiology involves a complex interplay of inflammation and tissue remodeling, and current treatment is limited by its impact on the pathophysiological mechanisms. In addition, despite clear environmental factors, family history is an important risk factor, suggesting a genetic component to the risk of developing VVs. Our understanding of the pathogenesis of these diseases has benefited greatly from the expansion of population genetic studies, from pioneering family studies to large genome-wide association studies; we now find multiple risk loci for each venous disease. This review considers the pathophysiology of VVs, highlighting the current state of genetic knowledge. We also propose future directions for research.

Abstract
Objective: Chronic venous ulcers are a relatively common and distressing condition that disproportionately affects older individuals. Along with multiple concomitant issues such as wound drainage, pain, and mobility impairments, individuals with chronic venous leg ulcers (CVLUs) commonly report sleep disturbances and fatigue; however, limited research has examined these symptoms in relation to inflammatory biomarkers in this population over the intensive wound care treatment trajectory. This study aimed at describing the symptoms of sleep and fatigue in older adults with CVLUs receiving intensive wound treatment with weekly debridement and exploring the relationships between these symptoms and tumor necrosis factor-alpha (TNF-α), c-reactive protein (CRP), and interleukin (IL)-6. Approach: Demographics, clinical characteristics, Pittsburgh Sleep Quality Index (PSQI) scores, Brief Fatigue Inventory (BFI), TNF-α, CRP, and IL-6 levels were collected from 84 older adults with CVLUs at three time points (baseline, week 4, and week 8). Data analysis included descriptive statistics and Bayesian estimation of associations. Results: Findings showed a consistent pattern of poor sleep quality and mild fatigue among these individuals. Lower IL-6 levels at week 4 and higher CRP levels at week 8 were linked to poor sleep quality. Higher CRP levels were linked to greater fatigue at baseline and week 8. Sleep and fatigue were correlated at all time points. Innovation and Conclusion: This study highlights the importance of clinicians evaluating sleep and fatigue in those with CVLUs. Further research is needed to validate circulating inflammatory biomarkers to enhance our understanding of sleep and fatigue's role in wound healing.

Abstract
Objective We sought to examine the role of flavonoids, particularly diosmin, as a therapeutic agent for stasis dermatitis (SD) through discussion of pathophysiology, current treatment paradigms, potential mechanisms of action, and a systematic review of evidence on clinical efficacy. Methods In addition to articles on pathophysiology and standard treatment, a search of PubMed was conducted using the following query: ("Diosmin" OR "MPFF" OR "Micronized Purified Flavonoid Fraction" OR "Flavonoid") AND ("Stasis Dermatitis" OR "Venous Ulcer" OR "Lipodermatosclerosis"). Emphasis was placed on studies that were randomized controlled trials examining an oral flavonoid against a placebo or standard of care. Results Diosmin is effective at improving stasis changes, increasing ulcer healing frequency, decreasing the time to ulcer healing, and reducing tissue edema. They also cause significant improvement in patient quality of life and reduction of venous symptoms. Diosmin has been shown to have a favorable safety profile with very few mild adverse events which did not differ significantly from placebo. Flavonoids also appear to be effective for other dermatologic conditions, including rosacea and senile purpura. Conclusion There is a growing body of evidence indicating that diosmin has therapeutic efficacy in managing stasis dermatitis. Data from studies in diseases with pathogenic similarities suggests the potential for even broader dermatologic applications.

Abstract
BACKGROUND Our aim is to evaluate the relationship between inspiratory muscle strength and venous refilling time, disease severity, and functional capacity in patients with chronic venous insufficiency (CVI). METHODS Sixty-one patients (49 female, aged 20-65 ) were enrolled in the study. The demographic characteristics of the patients were questioned. All patients were assessed with maximum inspiratory and expiratory pressure (MIP/MEP) for inspiratory and expiratory muscle strength, photoplethysmography for venous refilling time (VRT), venous clinical severity score (VCSS) for disease severity, and 6-min walk test (6-MWT) for functional capacity. RESULTS The mean age of the patients was 49.48 ± 13.19 years, and the mean duration of disease was 9.18 ± 6.57 years. There was statistically significant positive association between MIP and VRT(r: 0.331, p: 0.009), 6-MWT (r: 0.616, p < 0.001) values, and there was negative association between MIP and VCSS(r: -0.439 p < 0.001) scores. CONCLUSION Evaluation of inspiratory muscle strength and elimination of its deficiency, providing interventions to approach normative values have the potential to contribute positively to the treatment of the patient.

Abstract
Leg ulcers pose a significant challenge to healthcare services, requiring effective wound cleansing strategies to promote healing and prevent complications. Large amounts of nursing time is spent managing patients with venous leg ulcers (VLUs), with an average appointment time of approximately 30 minutes. Yet, there is a lack of clear guidance for the treatment of VLUs, with nurses adopting a wide range of cleansing practices. This commentary provides an overview of existing evidence on wound cleansing and care in treating leg ulcers, for the benefit of healthcare professionals working within clinical practice.

Abstract
BACKGROUND Clinical guidelines aim to consolidate and incorporate the latest evidence and opinion to improve patient outcomes and reduce variations in practice. AIMS AND METHODS This article will examine the evolution of clinical guidelines and recommendations in leg ulcer assessment and management, from the seminal Royal College of Nursing clinical guideline (1998) to the current Leg Ulcer Recommendations from the National Wound Care Strategy Program (2023). The evolving definitions of leg ulcers will be discussed, as well as the multidisciplinary approach needed to manage the underlying aetiology of this condition. FINDINGS AND CONCLUSION A national appetite for improving leg ulcer assessment and treatment, is being informed by clinical guidelines and recommendations. The cornerstones of assessment and management remain constant, although some fundamental elements around ankle brachial pressure index ranges, historically used to aid diagnosis of leg ulcer aetiology, have been omitted in the recent recommendations.

Abstract
Determining the precise role of molecular factors present in venous leg ulcer exudate will expedite the identification of biomarkers that can optimally guide treatment. However, there is now no standardized approach for collecting, processing and storing wound fluid samples for molecular analyses. This scoping review was conducted to integrate and summarize the multiple types of methods being used currently in studies of venous leg ulcers for collecting, processing and storing wound fluid prior to analysis. PubMed, CINAHL, EMBASE and Scopus databases were searched for eligible studies between 2012 and 2022. Nineteen studies were selected for this scoping review. Five primary methodological categories for wound fluid sampling were identified. The most commonly used collection method involved extracting the fluid from various absorbent materials, and the majority of studies centrifuged wound fluid before storing it at ultra-low temperatures. This review found the wound fluid sampling methods among the included studies to be heterogeneous. Moreover, the data revealed no definitive patterns. There is a critical need to develop standardized wound fluid sampling methods in research to facilitate accurate comparisons of biomarker data across studies and a more rapid determination of biomarkers that can most effectively guide delivery of tailored venous leg ulcer treatments.

Abstract
To systematically evaluate the clinical effects of platelet-rich plasma in the treatment of lower limb venous ulcers by applying a meta-analysis method. The Pubmed, Cochrance Library, Embase, and OVID EBM Reviews databases were searched for the search terms'platelet-rich plasma" or "Plasma, Platelet-Rich" or "Platelet Rich Plasma" and "lower extremity venous ulcers' or "Leg Ulcers' or "Ulcer, Leg", and a meta-analysis was performed on the published research literature on platelet-rich plasma for lower extremity venous ulcers from January 1900 to April 2021. The outcome indicators were: post-treatment trauma area and healing rate. Revman 5.3 statistical software was applied for meta-analysis. A total of 294 patients with lower extremity venous ulcers were included in six publications, including 148 patients in the experimental group treated with PRP versus 146 patients in the control group treated with conventional therapy. There was a statistically significant difference in the Formula of an ellipse at the end of treatment (CM²) between the experimental group and the control group, with a mean difference of -1.19 (95% CI -1.80 to -0.58, P = .0001; 6 studies, 294 participants moderate quality of evidence). The difference between the healing rate of the experimental group and the control group was statistically significant, with a risk ratio (RR) of 5.73 (95% CI 3.29 - 9.99, P < .00001; 5 studies, 248 participants moderate quality of evidence).There may be publication bias for both Formula of an ellipse at the end of treatment and healing rate. This comprehensive meta-analysis of available evidence suggests that the application of PRP for lower extremity venous ulcers accelerates the wound healing process and improves wound healing rates.

Ziel dieser Studie war es, die Ulkuslokalisation als diagnostisches Kriterium zu bewerten und einen diagnostischen Algorithmus zur Unterstützung in der Diagnostik bereitzustellen.Patienten und MethodikDie Studie umfasste 277 Patienten mit Ulcera cruris. Es wurden die folgenden fünf Gruppen definiert: Ulcus cruris venosum, arterielle Ulzera, gemischte Ulzera, Arteriolosklerose und Vaskulitis. Mittels computergestütztem Oberflächenrendering wurden die Prädilektionsstellen der verschiedenen Ulkustypen bewertet. Die Ergebnisse wurden in ein multinomiales logistisches Regressionsmodell integriert, um die Wahrscheinlichkeit einer bestimmten Diagnose in Abhängigkeit von Lokalisation, Alter, bilateraler Beteiligung und Anzahl der Ulzera zu berechnen. Zusätzlich wurde eine neuronale Netzwerk‐Bildanalyse durchgeführt.ErgebnisseDie Mehrheit der venösen Ulzera fand sich in der medialen Malleolarregion. Arterielle Ulzera waren am häufigsten auf der dorsalen Seite des Vorfußes zu finden. Arteriolosklerotische Ulzera waren zumeist im mittleren Drittel des lateralen Unterschenkels lokalisiert. Vaskulitische Ulzera schienen zufällig verteilt zu sein und waren deutlich kleiner, häufiger multilokulär und bilateral. Das multinomiale logistische Regressionsmodell zeigte eine insgesamt zufriedenstellende Leistung mit einer geschätzten Genauigkeit von 0,68 bei ungesehenen Daten.SchlussfolgerungenDer vorgestellte Algorithmus auf Grundlage der Ulkuslokalisation kann als unterstützendes Instrument zur Eingrenzung potenzieller Differenzialdiagnosen und als Hilfestellung für die Einleitung diagnostischer Maßnahmen dienen.

Abstract
We aimed to review and synthesise the evidence of the interventions of patients' and informal caregivers' engagement in managing chronic wounds at home. The research team used a systematic review methodology based on an updated guideline for reporting systematic reviews (PRISMA) and recommendations from the Synthesis Without Meta-analysis. Cochrane Central Register of Controlled Trial of the Cochrane Library, Pubmed, Embase, CINAHL, Wanfang (Chinese), and CNKI database (Chinese) were searched from inception to May 2022. The following MESH terms were used: wound healing, pressure ulcer, leg ulcer, diabetic foot, skin ulcer, surgical wound, educational, patient education, counselling, self-care, self-management, social support, and family caregiver. Experimental studies involving participants with chronic wounds (not at risk of wounds) and their informal caregivers were screened. Data were extracted and the narrative was synthesised from the findings of included studies. By screening the above databases, 790 studies were retrieved, and 16 met the inclusion and exclusion criteria. Studies were 6 RCTs and ten non-RCTs. Outcomes of chronic wound management included patient indicators, wound indicators, and family/caregiver indicators. Home-based interventions of patients or informal caregivers' engagement in managing chronic wounds at home may effectively improve patient outcomes and change wound care behaviour. What's more, educational/behavioural interventions were the primary type of intervention. Multiform integration of education and skills training on wound care and aetiology-based treatment was delivered to patients and caregivers. Besides, there are no studies entirely targeting elderly patients. Home-based chronic wound care training was important to patients with chronic wounds and their family caregivers, which may advance wound management outcomes. However, the findings of this systematic review were based on relatively small studies. We need more exploration of self and family-oriented interventions in the future, especially for older people affected by chronic wounds.

Abstract
BACKGROUND Diagnostic work-up of leg ulcers is time- and cost-intensive. This study aimed at evaluating ulcer location as a diagnostic criterium and providing a diagnostic algorithm to facilitate differential diagnosis. PATIENTS AND METHODS The study consisted of 277 patients with lower leg ulcers. The following five groups were defined: Venous leg ulcer, arterial ulcers, mixed ulcer, arteriolosclerosis, and vasculitis. Using computational surface rendering, predilection sites of different ulcer types were evaluated. The results were integrated in a multinomial logistic regression model to calculate the likelihood of a specific diagnosis depending on location, age, bilateral involvement, and ulcer count. Additionally, neural network image analysis was performed. RESULTS The majority of venous ulcers extended to the medial malleolar region. Arterial ulcers were most frequently located on the dorsal aspect of the forefoot. Arteriolosclerotic ulcers were distinctly localized at the middle third of the lower leg. Vasculitic ulcers appeared to be randomly distributed and were markedly smaller, multilocular and bilateral. The multinomial logistic regression model showed an overall satisfactory performance with an estimated accuracy of 0.68 on unseen data. CONCLUSIONS The presented algorithm based on ulcer location may serve as a basic tool to narrow down potential diagnoses and guide further diagnostic work-up.

Abstract
The process of healing venous ulcers is complex and influenced by many factors. By identifying the risk factors that influence a slower healing process, it is possible to predict impending delays and plan an individualised care plan. We analysed our database of patients with venous ulcers and identified clinical and demographic factors that delay the healing process. The research analysed the medical records of 754 patients with VLUs at Chronic Wound Treatment Unit of the University Hospital treated between 2001 and 2019. In study, the majority (64.3%) were women, the mean age was 65.7 years. The median duration of Chronic Venous Insufficiency was 24 years, 52% patients had had the disease >20 years, and 296 (39.3%) had experienced ulceration >12 months. Most of the patients (85.8%) had comorbidities, 84% were obese. At 12-week follow-up, 432 of the 754 ulcers had healed. Identified independent predictors of slower ulcer healing rates: wound area greater than 8.25 cm2 , location of the ulceration other than the medial ankle area, underlying disease >20 years, the presence of multiple comorbidities, depth of the ulcer, the presence of an unpleasant smell and alert pathogens. The presence of redness resulted in faster healing of VLUc. Many factors influence the healing process of venous ulceration. The results of the study can help in planning patient care and implementing appropriate early strategies to promote healing.

J Vasc Surg Venous Lymphat Disord 2023; 11:1130-1138. [PMID: 37579944 DOI: 10.1016/j.jvsv.2023.06.015] [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: 01/18/2023] [Revised: 05/04/2023] [Accepted: 06/08/2023] [Indexed: 08/16/2023]
Abstract
OBJECTIVE Remaining symptoms after treatment of superficial venous incompetence is a common problem. Duplex ultrasound is often used during follow-up, but does not permit an overall quantification of venous function. We have developed a plethysmographic method using occlusion cuffs for separation of superficial and deep venous reflux. By assessing the superficial component it is possible to quantify a potential suboptimal hemodynamic treatment in patients with superficial venous incompetence. The aim was to examine whether patients with hemodynamically quantifiable remaining reflux after treatment experience impaired clinical outcomes. METHODS This single-center prospective cohort study evaluated 156 limbs with great saphenous vein incompetence treated with radiofrequency ablation or high ligation and stripping. Duplex ultrasound and strain-gauge plethysmography (SGP) with and without selective superficial occlusion were performed before and one-year after treatment. Time taken (seconds) to reach 50% of the venous volume (T50) was evaluated. A difference in the T50of >5 seconds between postoperative strain-gauge plethysmography with and without superficial occlusion was defined as remaining reflux. The Venous Clinical Severity Score (VCSS) and Aberdeen Varicose Vein Questionnaire (AVVQ) were evaluated and compared between patients with and without remaining reflux. Multivariable logistic regression was used to evaluate risk factors for remaining plethysmographic reflux. RESULTS In all patients, median (25th, 75th percentile) T50 increased preoperatively from 7 seconds (3, 12 seconds) to 17 seconds (11, 28 seconds) (P < .001) 1 year after treatment. The VCSS and AVVQ were reduced (VCSS, 8.0 [6.0, 10.0] vs 3.0 [1.0, 5.0] [P < .001]; AVVQ, 21.8 [15.8, 32.1] vs 6.4 [2.2, 11.0] [P < .001]). Of the 156 limbs, 87 (56%) demonstrated remaining reflux 1 year after treatment. Patients with remaining plethysmographic reflux displayed higher median (25th, 75th percentile) VCSS (3.0 [2.0, 5.0] vs 2.0 [1.0, 4.0]; P = .012) and AVVQ (7.5 [2.7, 14.9] vs 4.7 [1.6, 9.2]; P = .025). Multivariate logistic regression showed that higher preoperative C in the Clinical Etiology Anatomy Pathophysiology classification (CEAP) (odds ratio [OR], 2.9 [95% confidence interval [CI], 1.34-6.46), age (OR, 1.03; 95% CI, 1.001-1.065), small saphenous vein incompetence (OR, 4.2; 95% CI, 1.30-13.73) and postoperative great saphenous vein reflux below the treated area (OR, 2.16; 95% CI, 1.02-4.56) were significant risk factors for remaining plethysmographic reflux. CONCLUSIONS A majority of treated limbs showed quantifiable reflux 1 year after intervention and these patients displayed worse patient related outcomes assessed with the VCSS and AVVQ. Remaining plethysmographic reflux was associated with preoperative small saphenous vein incompetence and reflux below the treated area as well as advanced age and higher C in CEAP.

Assessing the healthcare costs associated with venous leg ulcer compression bandages - A scoping review. J Tissue Viability 2023; 32:618-626. [PMID: 37423836 DOI: 10.1016/j.jtv.2023.06.009] [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: 03/20/2023] [Revised: 06/22/2023] [Accepted: 06/26/2023] [Indexed: 07/11/2023]
Abstract
AIM To determine the monetary costs identified in economic evaluations of treatment with compression bandages among adults with venous leg ulcers (VLU). METHOD A scoping review of existing publications was conducted in February 2023. The Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines were used. RESULTS Ten studies met the inclusion criteria. To place the costs of treatment into context, these are reported in conjunction with the healing rates. Three comparisons were made: 1.4 layer compression versus no compression (3 studies). One study reported that 4 layer compression was more expensive than usual care (£804.03 vs £681.04, respectively), while the 2 other studies reported the converse (£145 vs £162, respectively) and all costs (£116.87 vs £240.28 respectively). Within the three studies, the odds of healing were statistically significantly greater with 4 layer bandaging (OR: 2.20; 95% CI: 1.54-3.15; p = 0.001).; 2.4 layer compression versus other compression (6 studies). For the three studies reporting the mean costs per patient associated with treatment (bandages alone), over the treatment period, analysis identified a mean difference (MD) in costs for 4 layer vs comparator 1 (2 layer compression, short-stretch compression, 2 layer compression hosiery, 2 layer cohesive compression, 2 layer compression) of -41.60 (95% CI: 91.40 to 8.20; p = 0.10). The OR of healing for 4 layer compression vs comparator 1 (2 layer compression, short-stretch compression, 2 layer compression hosiery, 2 layer cohesive compression, 2 layer compression) is: 0.70 (95% CI: 0.57-0.85; p = 0.004). For 4 layer vs comparator 2 (2 layer compression) the MD is: 14.00 (95% CI: 53.66 to -25.66; p < 0.49). The OR of healing for 4 layer compression vs comparator 2 (2 layer compression) is: 3.26 (95% CI: 2.54-4.18; p < 0.00001). For comparator 1 (2 layer compression, short-stretch compression, 2 layer compression hosiery, 2 layer cohesive compression, 2 layer compression) vs comparator 2 (2 layer compression) the MD in costs is: 55.60 (95% CI: 95.26 to -15.94; p = 0.006). The OR of healing with Comparator 1 (2 layer compression, short-stretch compression, 2 layer compression hosiery, 2 layer cohesive compression, 2 layer compression) is: 5.03 (95% CI:4.10-6.17; p < 0.00001). Three studies presented the mean annual costs per patient associated with treatment (all costs). The MD is 172 (150-194; p = 0.401), indicating no statistically significant difference in costs between the groups. All studies showed faster healing rates in the 4 layer study groups. 3. Compression wrap versus inelastic bandage (one study). Compression wrap was less expensive than inelastic bandage (£201 vs £335, respectively) with more wounds healing in the compression wrap group (78.8%, n = 26/33; 69.7%, n = 23/33). CONCLUSION The results for the analysis of costs varied across the included studies. As with the primary outcome, the results indicated that the costs of compression therapy are inconsistent. Given the methodological heterogeneity among studies, future studies in this area are needed and these should use specific methodological guidelines to generate high-quality health economic studies.

Abstract
Venous leg ulcers (VLU) represent a major public health challenge. Little is known about the prevalence and incidence of VLU internationally. Published studies are usually reporting different estimates because of disparities in study designs and measurement methods. Therefore, we conducted a systematic literature review and meta-analysis to identify the prevalence and incidence of VLU internationally and to characterise the population as reported in these studies. Studies were identified from searches in Medline (PubMed), CINAHL Complete (EBSCOhost), Embase, Scopus, Web of Science, LiSSa (Littérature Scientifique en Santé), Google Scholar and Cochrane Database of Systematic Reviews up to November 2022. Studies were included if their primary outcomes were reported as a period prevalence or point prevalence or cumulative incidence or incidence VLU rate. Fourteen studies met the inclusion criteria, 10 reporting estimates of prevalence, three reporting both prevalence and incidence estimates and one incidence. All were included in meta-analyses. The results show a pooled prevalence of 0.32% and a pooled incidence of 0.17%. Our results highlighted an extreme heterogeneity across effect sizes for both prevalence and incidence, which prevent a meaningful interpretation of pooled indexes and argue for further studies with specific prevalence-type reported and target population under study.

Abstract
INTRODUCTION Oxygen is pivotal for wound healing. Its lack or hypoxia can delay this process, especially in individuals with comorbidities, potentially resulting in complex or hard-to-heal wounds. The Colombian Association of Diabetes (ACD) and the Colombian Association of Internal Medicine (ACMI) collaborated with a diverse group of experts to provide recommendations on the efficacy and best practices of continuous transdermal oxygen therapy (TOTc) in the care of such wounds. METHOD A modified Delphi technique was employed to obtain controlled feedback and responses. Experts from various disciplines engaged in reviewing and discussing numerous relevant scientific studies, focusing on the role of TOTc in treating chronic ulcers. RESULTS Continuous transdermal oxygen therapy has proven to be an effective and safe treatment for chronic and/or hard-to-heal ulcers. This therapy directly addresses the wound's oxygen deficiency, providing an environment conducive to healing. Significant benefits were observed, including the acceleration of the healing process, wound size reduction, and an enhancement in patient quality of life. Its efficacy was found across various ulcer etiologies, underscoring its therapeutic versatility. CONCLUSIONS Continuous transdermal oxygen therapy is effective and safe for treating chronic and hard-to-heal ulcers. It's crucial to address each case individually and through a multidisciplinary approach to maximize this therapy's benefits. Both evidence and clinical experience back its utility across a variety of ulcer etiologies.

Abstract
Impaired wound healing after trauma, disorders, and surgeries impact millions of people globally every year. Dysregulation in orchestrated healing mechanisms and underlying medical complications make chronic wound management extremely challenging. Besides standard-of-care treatments including broad spectrum antibiotics and wound-debridement, novel adjuvant therapies are clinically tested and commercialized. These include topical agents, skin substitutes, growth factor delivery, and stem cell therapies. With a goal to overcome factors playing pivotal role in delayed wound healing, researchers are exploring novel approaches to elicit desirable healing outcomes in chronic wounds. Although recent innovations in wound care products, therapies, and devices are extensively reviewed in past, a comprehensive review summarizing their clinical outcomes is surprisingly lacking. Herein, this work reviews the commercially available wound care products and their performance in clinical trials to provide a statistically comprehensive understanding of their safety and efficacy. The performance and suitability of various commercial wound care platforms, including xenogeneic and allogenic products, wound care devices, and novel biomaterials, are discussed for chronic wounds. The current clinical evaluation will provide a comprehensive understanding of the benefits and drawbacks of the most-recent approaches and will enable researchers and healthcare providers to develop next-generation technologies for chronic wound management.

Abstract
BACKGROUND Chronic venous insufficiency (CVI) is characterized by progressive inflammatory changes. Inflammatory damage occurs in the veins, adjacent tissues, and can lead to structural changes in the arteries. The aim of this study is to analyze whether the degree of CVI is associated with arterial stiffness. METHODS Cross-sectional study including patients with CVI classified by clinical, etiological, anatomical, and pathophysiological classification (CEAP) 1 to 6. We performed correlation between the degree of CVI, central and peripheral arterial pressure, and arterial stiffness measured by brachial artery oscillometry. RESULTS We evaluated 70 patients, 53 of whom were women with a mean age of 54.7 years. Patients with advanced degrees of venous insufficiency CEAP 4,5,6, had higher levels of systolic, diastolic, central, and peripheral arterial pressures compared to those with early stages (CEAP 1,2,3). The CEAP 4,5,6 group had higher arterial stiffness indices than the CEAP 1,2,3 group: pulse wave velocity (PWV) 9.3 m/s vs. 7.0 m/s, P < 0.001; augmentation pressure (AP) 8.0 mm Hg vs. 6.3 mm Hg; P = 0.04. There was a positive correlation between the degree of venous insufficiency measured by the venous clinical severity score, villalta score and CEAP classification, and the arterial stiffness indices (Spearman's coefficient = 0.62 for PWV and CEAP, P < 0.01). The factors influencing PWV were age, peripheral systolic arterial pressure (SAPp), and AP. CONCLUSIONS There is a correlation between the degree of venous disease and arterial structural changes characterized by arterial pressure and stiffness indices. Degenerative changes secondary to venous insufficiency are associated with impairment of the arterial system, which has implications for the development of cardiovascular disease.

Abstract
Impaired skin wound healing is a significant global health issue, especially among the elderly. Wound healing is a well-orchestrated process involving the sequential phases of inflammation, proliferation, and tissue remodeling. Although wound healing is a highly dynamic and energy-requiring process, the role of metabolism remains largely unexplored. By combining transcriptomics and metabolomics of human skin biopsy samples, we mapped the core bioenergetic and metabolic changes in normal acute as well as chronic wounds in elderly subjects. We found upregulation of glycolysis, the tricarboxylic acid cycle, glutaminolysis, and β-oxidation in the later stages of acute wound healing and in chronic wounds. To ascertain the role of these metabolic pathways on wound healing, we targeted each pathway in a wound healing assay as well as in a human skin explant model using metabolic inhibitors and stimulants. Enhancement or inhibition of glycolysis and, to a lesser extent, glutaminolysis had a far greater impact on wound healing than similar manipulations of oxidative phosphorylation and fatty acid β-oxidation. These findings increase the understanding of wound metabolism and identify glycolysis and glutaminolysis as potential targets for therapeutic intervention.

Carbohydr Polym 2023; 316:121077.

Abstract
Aldehyde-functionalized cellulose (AFC) was prepared by oxidizing cellulose with sodium metaperiodate. The reaction was characterized by Schiff's test, FT-IR, and UV-vis study. AFC was evaluated as a reactive sorbent for controlling polyamine-based odor from chronic wounds, and its performance was compared with charcoal, one of the most widely utilized odor-control sorbents through physisorption. Cadaverine was used as the model odor molecule. A liquid chromatography/mass spectrometry (LC/MS) method was established to quantify the compound. AFC was found to rapidly react with cadaverine through the Schiff-base reaction, which was confirmed by FT-IR, visual observation, CHN elemental analysis, and the ninhydrin test. The sorption and desorption behaviors of cadaverine onto AFC were quantified. With clinic-relevant cadaverine concentrations, AFC demonstrated much better sorption performance than charcoal. At even higher cadaverine concentrations charcoal showed higher sorption capacity, probably due to its high surface area. On the other hand, in desorption studies, AFC retained much more of the sorbed cadaverine than charcoal. When AFC and charcoal were combined, the pair demonstrated excellent sorption and desorption behaviors. The XTT (2,3-bis-(2-methoxy-4-nitro-5-sulfophenyl)-2H-tetrazolium-5-carboxanilide) assay confirmed that AFC has very good in vitro biocompatibility. These results suggest that AFC-based reactive sorption can be a new strategy to control odors associated with chronic wounds for improved healthcare.

Abstract
Non-healing wounds have a negative impact on quality of life and account for many cases of amputation and even early death among patients. Diabetic patients are the predominate population affected by these non-healing wounds. Despite the significant clinical demand, treatment with biologics has not broadly impacted clinical care. Interleukin-4 (IL-4) is a potent modulator of the immune system, capable of skewing macrophages towards a pro-regeneration phenotype (M2) and promoting angiogenesis, but can be toxic after frequent administration and is limited by its short half-life and low bioavailability. Here, we demonstrate the design and characterization of an engineered recombinant interleukin-4 construct. We utilize this collagen-binding, serum albumin-fused IL-4 variant (CBD-SA-IL-4) delivered in a hyaluronic acid (HA)-based gel for localized application of IL-4 to dermal wounds in a type 2 diabetic mouse model known for poor healing as proof-of-concept for improved tissue repair. Our studies indicate that CBD-SA-IL-4 is retained within the wound and can modulate the wound microenvironment through induction of M2 macrophages and angiogenesis. CBD-SA-IL-4 treatment significantly accelerated wound healing compared to native IL-4 and HA vehicle treatment without inducing systemic side effects. This CBD-SA-IL-4 construct can address the underlying immune dysfunction present in the non-healing wound, leading to more effective tissue healing in the clinic.

Abstract
OBJECTIVE The benefit of using electric stimulation therapy (EST) to heal venous leg ulcers (VLUs) is not well established. The main aim of this systematic review was to evaluate the effects of ulcer EST in VLU healing. METHODS A systematic search of the literature was conducted using the databases PubMed, Scopus, and Web of Science and included original studies that reported VLU healing after EST. The inclusion criteria were at least two surface electrodes placed on or near the wound or a planar probe covering the ulcer area to be treated. The Cochrane risk of bias tool for randomized control trials (RCTs) and Joanna Briggs Institute critical appraisal checklist for case series were used to evaluate the risk of bias. RESULTS This review included eight RCTs and three case series involving a total of 724 limbs in 716 patients with VLUs. The mean patient age was 64.2 years (95% confidence interval, 62.3-66.2), and 46.2% (95% confidence interval, 41.2%-50.4%) were men. The active electrode was placed on the wound with the passive electrode placed on healthy skin (n = 6), the two electrodes were placed on either side of the wound edges (n = 4), or a planar probe was used (n = 1). The pulsed current was the most used waveform (n = 9). The change in the ulcer size was the main method used to determine ulcer healing (n = 8), followed by the ulcer healing rate (n = 6), exudate levels (n = 4), and the time to healing (n = 3). Five RCTs detected a statistically significant improvement in at least one VLU healing outcome, after EST compared with the control group. In two of these, EST was better than the control but only for patients who had not undergone surgical treatment of VLU. CONCLUSIONS The findings from the present systematic review support the use of EST to accelerate wound healing of VLUs, especially for patients who are not surgical candidates. However, the significant variation in electric stimulation protocols represents an important limitation to its use and should be addressed in future studies.

Abstract
Studies have reported that the constituents of the wound microenvironment are likely to have critical roles in the degradation and fate of the polymeric matrix and the compounds dissolved in the wound dressing matrix. Thus, chronic wound assessment and the design of effective medical devices and drug products for wound care partly rely on an in-depth understanding of the wound microenvironment. The main aim of this review is to identify and discuss the different stages of chronic wound progression, focusing on the changes in the biochemical composition of the wound microenvironment, with particular attention given to venous leg ulcers (VLUs), as they are one of the most prevalent chronic wound aetiologies. The pathophysiology of venous ulcers is detailed, followed by a thorough review of what is known about the VLU microenvironment and its changes as a function of the evolution of the VLU. Simulating conditions for VLU are then discussed with the view of highlighting potentially relevant simulating media as a function of VLU evolution for a better assessment of biological safety, in particular medical devices intended to be in contact with these wounds.

Abstract
Background: Compression therapy is the gold standard for the treatment of chronic venous insufficiency (CVI). Two-layer bandage (2LB) systems have been shown to be a safe and effective treatment option. Objective: To estimate the total cost per response (CPR) for the resolution of edema and wounds in patients with CVI treated with a 2LB system as part of their overall wound healing regimen. Methods: A probabilistic decision tree model was developed to estimate the incremental CPR for a 2LB system. The model simulated 10 000 patients to estimate the CPR for the resolution of edema and wound healing. The analysis was performed using clinical data from a published single-arm, multicenter prospective study of CVI indicated for compression therapy. The response outcomes of interest were resolution of edema and rate of wound healing. The follow-up time was a maximum of 6 weeks, and the perspective of the study was a US outpatient treatment center. Economic data for compression therapy were based on the public prices of a 2LB system. Dressing changes occurred per manufacturer instructions for use. Results: The study comprised 702 patients (56% female), with a total of 414 wounds. The median duration of the wounds was 42 days, and the median size at the initial visit was 3.5 cm2. The average pain reduction fell by 67% using a visual analog score. Bandages were typically changed once or twice a week (51.7%). Wound healing occurred in 128 of the 414 wounds (30.9%). The expected incremental CPR of a 2LB system for the resolution of edema was $65.67 (range, $16.67-$124.32). The expected incremental CPR of a 2LB system for the healing of a wound was $138.71 (range, $35.71-$273.53). Conclusion: This economic evaluation complements previous clinical effectiveness and safety studies of 2LB systems for the treatment of CVI. The results demonstrate that the costs of incorporating 2LB into standard wound-healing protocols are negligible compared with overall treatment costs. Two-layer bandages may be considered a cost-effective first-line system for the treatment of wounds caused by CVI.

Abstract
Introduction Wound management is a challenge in terms of the way, duration and cost of treatment both for the patient and health providers. The healing of skin wounds is a highly multi-step coordinated process. Objective monitoring of treatment at every stage is necessary to assess the applied therapy. Aim To show the possibility of using the AutoCad software (ACS) as a tool with a slight measurement error for accurate measurement of the venous leg ulcers on the lower limbs. Material and methods To determine the error of the measurement method Circle Templates For Drafting for four different sizes were used as ulcer models. Seventy-six wounds of various sizes from patients with venous leg ulcers (VLUs) were photographed and outlined with a marker on a transparent foil. The wounds were measured both using ACS and digital planimetry with C-Geo software (CGS). Data were analysed using Wilcoxon test, intraclass correlation coefficient (ICC) and Bland-Altman analysis. Results The mean relative error of the surface wound model area measured by the ACS was 0.30 ±0.31% (range: 0.004-1.25) and a median of 0.18%. Areas and perimeters measured with ACS were higher than areas and perimeters measured with CGS, and the difference was statistically significant. Conclusions The analysis of the wound images obtained in the ACS showed a very high potential of the software in terms of the accuracy of the analysed areas, which significantly increases the possibility of the analysis and reduces the measurement error in relation to planimetry using a digital digitizer.

Abstract
Background Impaired wound healing is the most common and significant complication of Diabetes. While most other complications of Diabetes have better treatment options, diabetic wounds remain a burden as they can cause pain and suffering in patients. Wound closure and repair are orchestrated by a sequence of events aided by the release of pro-inflammatory cytokines, which are dysregulated in cases of Diabetes, making the wound environment unfavorable for healing and delaying the wound healing processes. This concise review provides an overview of the dysregulation of pro-inflammatory cytokines and offers insights into better therapeutic outcomes. Purpose of review Although many therapeutic approaches have been lined up nowadays to treat Diabetes, there are no proper treatment modalities proposed yet in treating diabetic wounds due to the lack of understanding about the role of inflammatory mediators, especially Pro-inflammatory mediators- Cytokines, in the process of Wound healing which we mainly focus on this review. Recent findings Although complications of Diabetes mellitus are most reported after years of diagnosis, the most severe critical complication is impaired Wound Healing among Diabetes patients. Even though Trauma, Peripheral Artery Disease, and Peripheral Neuropathy are the leading triggering factors for the development of ulcerations, the most significant issue contributing to the development of complicated cutaneous wounds is wound healing impairment. It may even end up with amputation. Newer therapeutic approaches such as incorporating the additives in the present dressing materials, which include antimicrobial molecules and immunomodulatory cytokines is of better therapeutic value. Summary The adoption of these technologies and the establishment of novel therapeutic interventions is difficult since there is a gap in terms of a complete understanding of the pathophysiological mechanisms at the cellular and molecular level and the lack of data in terms of the assessment of safety and bioavailability differences in the individuals' patients. The target-specific pro-inflammatory cytokines-based therapies, either by upregulation or downregulation of them, will be helpful in the wound healing process and thereby enhances the Quality of life in patients, which is the goal of drug therapy.

Abstract
OBJECTIVE Sclerotherapy is an accepted treatment modality for reticular varicose veins and telangiectasia. We aimed to compare the success and safety of foam and liquid sclerotherapy in obese patients with lower extremity varicose veins and telangiectasia. METHODS The present study was performed in a non-randomized prospective manner, and obese patients with lower extremity varicose veins (patients with anatomy and pathophysiology classification {CEAP} class C1) and telangiectasia treated with foam sclerotherapy and liquid sclerotherapy were enrolled into the study. Patients treated with foam sclerotherapy and liquid sclerotherapy were compared with regard to preoperative parameters, procedure success, Visual Analog Score (VAS), patient satisfaction, and complications. RESULTS The VAS scores at the first hour and sixth hour were statistically higher in the foam sclerotherapy group (p=0.001 and p=0.001, respectively). The success rate after the first session was 88.2% in the foam sclerotherapy group and 69.4% in the liquid sclerotherapy group (p=0.008). After all sessions, the success rates were similar between groups (p=0.607). The foam sclerotherapy group required an average of 1.1 sessions, while the liquid sclerotherapy group required 1.4 sessions (p=0.001). At the third-month follow-up, the success rate was significantly higher in the foam sclerotherapy group than liquid sclerotherapy group (91.2% and 77.4%; p= 0.030). In the foam sclerotherapy group, 80.9% of the patients were very satisfied, while this rate was 58.1% in the liquid group (p=0.012). The rates of ecchymosis and hyperpigmentation in the first week after the procedure were significantly higher in the foam sclerotherapy group (p=0.003 and p=0.040, respectively). CONCLUSION Our findings showed that foam sclerotherapy had a significantly higher success rate after the first session, and third month follow-up with higher patient satisfaction. In contrast, liquid sclerotherapy had significantly lower VAS scores in the first and sixth hours following the procedure and had lower ecchymosis and hyperpigmentation in the first week after the procedure.
