Fan Q, Meng Y, Nie Z, Xie S, Chen C. Sex hormone-binding globulin exerts sex-related causal effects on lower extremity varicose veins: evidence from gender-stratified Mendelian randomization. Front Endocrinol (Lausanne) 2023; 14:1230955. [PMID: 38152135 PMCID: PMC10752419 DOI: 10.3389/fendo.2023.1230955] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 05/30/2023] [Accepted: 11/20/2023] [Indexed: 12/29/2023] Open
Abstract
Background The association between serum sex hormones and lower extremity varicose veins has been reported in observational studies. However, it is unclear whether the association reflects a causal relationship. Besides, serum sex hormone-binding globulin (SHBG) has been rarely studied in lower extremity varicose veins. Here, we aim to investigate the association between serum levels of SHBG, testosterone, and estradiol and the risk of lower extremity varicose veins using Mendelian randomization (MR). Methods We obtained genome-wide association study summary statistics for serum SHBG levels with 369,002 European participants, serum testosterone levels with 424,907 European participants, serum estradiol levels with 361,194 European participants, and lower extremity varicose veins with 207,055 European participants. First, a univariable MR was performed to identify the causality from SHBG and sex hormone levels to lower extremity varicose veins with several sensitivity analyses being performed. Then, a multivariable MR (MVMR) was performed to further assess whether the causal effects were independent. Finally, we performed a gender-stratified MR to understand the role of genders on lower extremity varicose veins. Results Genetically predicted higher serum SHBG levels significantly increased the risk of lower extremity varicose veins in the univariable MR analysis (OR=1.39; 95% CI: 1.13-1.70; P=1.58×10-3). Sensitivity analyses and MVMR (OR=1.50; 95% CI:1.13-1.99; P=5.61×10-3) verified the robustness of the causal relationships. Gender-stratified MR revealed that higher serum SHBG levels were associated with lower extremity varicose veins in both sexes. However, the OR of serum SHBG levels on lower extremity varicose veins risk in females (OR=1.51; 95% CI: 1.23-1.87; P=1.00×10-4) was greater than in males (OR=1.26; 95% CI: 1.04-1.54; P=1.86×10-2). Conclusions Serum SHBG levels are positively related to lower extremity varicose veins risk in both sexes, especially in females. This may partly explain the higher prevalence of varicose vines among females.

Prevalence and associated factors of chronic venous disease among the modern Iranian urban population. J Vasc Surg Venous Lymphat Disord 2023; 11:1098-1106.e10. [PMID: 37690625 DOI: 10.1016/j.jvsv.2023.06.005] [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: 01/12/2023] [Revised: 05/17/2023] [Accepted: 06/08/2023] [Indexed: 09/12/2023]
Abstract
OBJECTIVES Chronic venous disease (CVD) of the lower extremities is one of the common venous diseases in different populations, with a wide range of clinical manifestations and undetermined exact prevalence owing to different population characteristics and measurement methods. This study aimed to estimate the prevalence of CVD among the modern Iranian urban population and determine its associated risk factors. METHODS The Heart Assessment and Monitoring in Rajaie Hospital study, a longitudinal population-based cohort, aims to investigate the baseline prevalence and the 10-year incidence of cardiovascular diseases and associated risk factors in the adult population aged 30 to 75 years with no overt cardiovascular diseases in Tehran. Two instructed interventional cardiologists performed CVD evaluation using the Clinical-Etiology-Anatomy-Pathophysiology classification. CVD was graded as C1 to C6, and chronic venous insufficiency (CVI) as C3 to C6. A multivariable regression model was used to analyze the association between CVD and prespecified covariates of age, sex, body mass index (≥30 kg/m2), smoking, hypertension, diabetes mellitus, physical activity, dyslipidemia, and delivery method. RESULTS CVD prevalence among 1176 participants was 36.5% (95% confidence interval [CI], 33.8-39.3) and was higher in women than men (44.2% vs 23.5%). CVI prevalence was only 0.7% (95% CI, 0.3-1.3). Multivariable analysis showed that advanced age (odds ratio [OR], 1.06; 95% CI, 1.04-1.08), female sex (OR, 2.98; 95% CI, 2.14-4.14), and body mass index of ≥30 (OR, 1.36; 95% CI, 1.03-1.81) were independently associated with CVD. Physical activity (OR, 0.77; 95% CI, 0.58-1.02) was nearly protective, whereas other factors, including traditional cardiovascular risk factors, had no meaningful association with CVD. CONCLUSIONS Our findings showed that CVD was prevalent in the modern Iranian urban population. However, considering the very low prevalence of the higher stages of the disease, the benefit of mass screening is debatable, and better risk discriminators should be investigated.

Abstract
OBJECTIVE To estimate the 'cost of illness' arising from chronic wounds in Singapore. DESIGN Incidence-based cost of illness study using evidence from a range of sources. SETTING Singapore health services. PARTICIPANTS We consider 3.49 million Singapore citizens and permanent residents. There are 16 752 new individuals with a chronic wound in 2017, with 598 venous ulcers, 2206 arterial insufficiency ulcers, 6680 diabetic ulcers and 7268 pressure injuries.Primary outcome measures expressed in monetary terms are the value of all hospital bed days lost for the population; monetary value of quality-adjusted life years (QALYs) lost in the population; costs of all outpatient visits; and costs of all poly clinic, use of Community Health Assist Scheme (CHAS) and emergency departments (EDs) visits. Intermediate outcomes that inform the primary outcomes are also estimated. RESULTS Total annual cost of illness was $350 million (range $72-$1779 million). With 168 503 acute bed days taken up annually (range 141 966-196 032) that incurred costs of $139 million (range 117-161 million). Total costs to health services were $184 million (range $120-$1179 million). Total annual costs of lost health outcomes were 2077 QALYs (range -2657 to 29 029) valued at $166 million (range -212 to 2399 million). CONCLUSIONS The costs of chronic wounds are large to Singapore. Costs can be reduced by making positive investments for comprehensive wound prevention and treatment programmes.

Abstract
Venous disease is prevalent, undertreated, and frequently unrecognized. During the past two decades, new treatment modalities have changed how venous disease is approached. Some of these treatment modalities are only available in certain centers or locations and access to care could be inequitable. Although venous disease affects millions in the United States, we have little understanding of the gender, socioeconomic, and ethnic disparities in both superficial and deep venous disease presentation. In an effort to better understand the treatment of male and female patients from different gender, ethnic, and socioeconomic backgrounds, literature searches were conducted to investigate how these patients were evaluated and treated. PubMed was used to search literature using the terms "venous insufficiency," "superficial venous disease," "venous thromboembolism," "deep vein thrombosis," "DVT," "May-Thurner," and "pulmonary embolism," with gender, sex, racial, and socioeconomic disparities and differences within the keywords. In addition, once articles were discovered, the "similar articles" function was used to expand the search. The included studies were restricted to those reported from 1995 to the present. Given the paucity of data, no study was excluded. It is readily apparent that there is not enough data to make decisions that would modify treatment to affect the outcomes of patients with differing backgrounds and gender. Studies currently are limited to evaluating patients by sex assigned at birth without interrogation of their identified gender. It is imperative that consideration is given to evaluating gender and ethnic differences, because treatment options might need to be tailored accordingly. Outreach and education for underserved patient populations with improvement in access to care must also be incorporated into the healthcare system. Additional work in this area is required. Further data collection and research related to demographic disparities among patients with venous disease is necessary to better understand the differences that could change treatment algorithms tailored to specific groups.

Abstract
Introduction Varicose veins are a common chronic disease that creates a significant economic burden on the healthcare system. Current treatment options, including pharmacological treatments, are not always effective, and there is a need for more targeted therapies. A Mendelian randomization (MR) method uses genetic variants as instrumental variables to estimate the causal effect of an exposure on an outcome, and it has been successful in identifying therapeutic targets in other diseases. However, few studies have used MR to explore potential protein drug targets for varicose veins. Methods To identify potential drug targets for varicose veins of lower extremities, we undertook a comprehensive screen of plasma protein with a two-sample MR method. We used recently reported cis-variants as genetic instruments of 2,004 plasma proteins, then applied MR to a recent meta-analysis of genome-wide association study on varicose veins (22,037 cases and 437,665 controls). Furthermore, pleiotropy detection, reverse causality testing, colocalization analysis, and external replication were utilized to strengthen the causal effects of prioritized proteins. Phenome-wide MR (PheW-MR) of the prioritized proteins for the risk of 525 diseases was conducted to screen potential side effects. Results We identified eight plasma proteins that are significantly associated with the risk of varicose veins after Bonferroni correction (P < 2.495 × 10-5), with five being protective (LUM, POSTN, RPN1, RSPO3, and VAT1) and three harmful (COLEC11, IRF3, and SARS2). Most identified proteins showed no pleiotropic effects except for COLLEC11. Bidirectional MR and MR Steiger testing excluded reverse causal relationship between varicose veins and prioritized proteins. The colocalization analysis indicated that COLEC11, IRF3, LUM, POSTN, RSPO3, and SARS2 shared the same causal variant with varicose veins. Finally, seven identified proteins replicated with alternative instruments except for VAT1. Furthermore, PheW-MR revealed that only IRF3 had potential harmful adverse side effects. Conclusions We identified eight potential causal proteins for varicose veins with MR. A comprehensive analysis indicated that IRF3, LUM, POSTN, RSPO3, and SARS2 might be potential drug targets for varicose veins.

Abstract
Stasis dermatitis is a chronic inflammatory skin disease of the lower extremities. It typically occurs in older individuals and is the cutaneous manifestation of venous hypertension caused by venous reflux. Such retrograde venous blood flow is the result of incompetent venous valves, valve destruction, or venous obstruction. Stasis dermatitis is eczematous. The associated impairment of venous valves may cause swelling of the legs, leading to serious conditions including venous ulcerations. Diagnosis can be challenging because of its clinical resemblance to other skin conditions and poor clinical recognition by physicians. The cornerstones of stasis dermatitis treatment are compression therapy to ameliorate pain and swelling, topical treatments to alleviate secondary skin changes, and interventional treatment options to correct the underlying causes of venous reflux. Given the central role of inflammation of the lower extremities in driving the cutaneous changes characteristic of stasis dermatitis, new therapeutic approaches that target the inflammation are under clinical evaluation in patients with stasis dermatitis.

Abstract
Varicose veins are convoluted, expanded, and stretched subcutaneous veins of the lower leg and are the most frequently reported medical condition. This condition has a higher prevalence in Western and developed countries. Inadequacy of the valves results in reflux of blood in the veins of the lower leg. The present study aims to describe the epidemiology and contributing factors (risk factors and pathological factors) in the development of varicose veins disease. PubMed/Medline, Science Direct, Google Scholar, SciFinder, Scopus, and Web of Science databases were explored to include potential research and review articles. Finally, 65 articles were considered appropriate to include in the study. Pain, swelling, heaviness, and tingling of the lower limbs are the most common sign and symptoms caused by varicose veins while in some individuals it is asymptomatic. The Prevalence of varicose veins varies geographically. Currently, it is reported that globally about 2%–73% of the population is affected by varicose veins while the prevalence rate in Pakistan is 16%–20%. Different risk factors associated with the advancement of varicose veins are age, gender, occupation, pregnancy, family history, smoking, BMI and obesity, exercise, genetic factor, and current lifestyle. In varicose veins, some contributory elements may also play an important role in the disease development, incorporating constant venous wall aggravation, hereditary variation, and persistent venous hypertension. This condition has now turned into a curable issue that was previously viewed broadly as less important for treatment, determining the individual’s satisfaction. Moreover, the mechanisms behind the risk factors involve diet, physical work, and hormonal contribution. These are more likely to be explored.

Abstract
Compression, skin care, manual lymph drainage and exercise form the mainstays of treatment of chronic limb oedema. The compression aspect of the regimen is often prescribed and used without conscious concern for the patient's ability for self-adjustment and skin hygiene. This article will focus on the action of compression therapy using a new concept of encouraging patients to apply and reapply an adjustable compression garment or multiple garment types during a 24-hour interval. The benefits of this focus on interval compression therapy on all aspects of care will be explained and case studies presented.

Abstract
Significance: Chronic venous disease (CVD) is prevalent in the aging population and leads to venous leg ulcers (VLUs). These wounds can last and recur for years, significantly impacting quality of life. A large body of literature exists on CVD and VLU diagnosis and treatment. Multiple algorithms, guidelines, and consensus documents have been published on this topic, highlighting the importance of this issue in clinical practice. However, these documents are not fully aligned with each other. Recent Advances: The latest update of the internationally used classification system for CVD was recently published. Our review aims to summarize the existing information to provide an educational tool for clinicians new to this topic, and to highlight the commonalities between the published recommendations. Critical issues: VLUs need to be treated with consideration for the extent of venous disease present in the patient. This requires a good understanding of the various components involved and the possible additional concomitant conditions by the first-line clinician who encounters the patient. A multidisciplinary team is necessary for a successful overall treatment plan, and this plan should be tailored to each patient's specific needs and lifestyle. Future Directions: Compression is still the mainstay of treatment for CVD and VLUs. Compression is needed long term, but it does not suffice by itself to prevent recurrences without interventional correction. Venous intervention should be offered early to prevent or slow disease progression and reduce recurrence.

Abstract
OBJECTIVES The association between socioeconomic status (SES) and chronic venous insufficiency has not been rigorously studied. This study aimed to determine the influence of SES on the clinical stage of patients presenting for chronic venous disease therapy. METHODS We performed a retrospective study of a prospectively collected data from the Vascular Quality Initiative Varicose Vein Registry at our tertiary referral center. Medical records of patients who underwent therapy for chronic venous disease between January 2015 and June 2019 were queried. SES was quantified using the neighborhood deprivation index (NDI), which summarizes 8 domains of socioeconomic deprivation and is based on census tract data derived from the patients' addresses at the time of the treatment. High NDI scores correspond with lower SES. The association between SES and severity of vein disease at presentation was assessed with bivariate analysis of variance and linear regression analysis. RESULTS A total of 449 patients with complete SES and clinical-etiology-anatomy-pathophysiology (CEAP) class data were included in the study. The mean age was 58 years, 67% were female, and 60% were White. CEAP classes were distributed as follows C2, 22%; C3, 50%; C4, 15%; C5, 5%; and C6, 8%. Patients with lower SES (higher NDI score) tended to have a higher CEAP class at presentation (P < 0.05). SES was not associated with history of deep venous thrombosis, use of compression therapy, or venous clinical severity score. CONCLUSIONS At our institution, patients with more advanced venous disease tended to belong to a lower SES group. This may reflect that patients with a lower SES have a longer time to presentation due to delay in seeking medical help for venous disease.

Abstract
Chronic wounds have a debilitating effect on the quality of life of many individuals, and the large economic impact on health system budgets warrants greater attention in policy making and condition management than is currently evident. The aim of this narrative review is to summarize the nature and extent of the chronic wound problem that confronts health systems across the world. The first section is used to highlight the underlying epidemiology relating to chronic wounds, while the second explores the economic costs associated with them and the relative efficiency of measures designed to manage them.

Abstract
OBJECTIVE The aim of the present study was to examine whether severe chronic venous disease (CVD) is associated with a greater risk of major adverse cardiovascular events (MACE) compared with mild CVD. METHODS Participants with CVD were prospectively recruited from outpatient vascular departments at two hospitals in North Queensland, Australia. CVD severity was ascertained by vascular specialists using the CEAP (clinical, etiologic, anatomic, pathophysiologic) classification. MACE, defined as myocardial infarction, stroke, or cardiovascular death, were identified from the outpatient follow-up and linked medical records. Kaplan-Meier and Cox proportional hazard analyses were used to examine the association of CVD severity with the occurrence of MACE. A subanalysis was performed in which participants with CEAP C5 and C6 (severe CVD) were compared with those with CEAP C2 to C4 (mild CVD). RESULTS A total of 774 participants were included and followed up for a median of 3.09 years (interquartile range, 1.09-8.14 years). The participants with C6 CVD (n = 69) had a threefold greater risk of MACE (hazard ratio, 3.03; 95% confidence interval, 1.02-9.03; P = .046) compared with those with C2 CVD (n = 326) after adjusting for other risk factors. Participants with severe CVD had an increased risk of MACE compared with those with mild CVD (adjusted hazard ratio, 2.37; 95% confidence interval, 1.12-5.04; P = .024). CONCLUSIONS Individuals with severe CVD have an increased risk of MACE compared with those with mild CVD, independently of traditional risk factors. Further research is required to clarify the cause of the excess risk.

Abstract
OBJECTIVE To provide an updated estimate of the global prevalence of CVD and to comprehensively evaluate risk factors associated with this condition. BACKGROUND Chronic Venous Disease (CVD) is an important cause of morbidity internationally, but the global burden of this condition is poorly characterised. The burden of CVD must be better characterised to optimise service provision and permit workforce planning to care for patients with different stages of CVD. METHODS A systematic search in Ovid MEDLINE and Embase (1946 - 2019) identified 1271 articles. Full-text, English language articles reporting on the epidemiology of CVD in a general adult population were included. Data extraction was performed by two independent reviewers, in accordance with a pre-registered protocol (PROSPERO: CRD42019153656). STATA and Review Manager were used for quantitative analysis. A crude, unadjusted pooled prevalence was calculated for each Clinical (C) stage in the Clinical, Etiologic, Anatomic, Pathophysiologic (CEAP) classification and across different geographical regions. Qualitative analysis was performed to evaluate associated risk factors in CVD. RESULTS 32 articles across 6 continents were identified. 19 studies were included in the overall pooled prevalence for each Clinical (C) stage; pooled estimates were: C0 s: 9%, C1: 26%, C2: 19%, C3: 8%, C4: 4%, C5: 1%, C6: 0·42%. The prevalence of C2 disease was highest in Western Europe and lowest in the Middle East and Africa. Commonly reported risk factors for CVD included: female gender (OR 2·26, 95% CI 2·16-2·36, p < 0.001), increasing age, obesity, prolonged standing, positive family history, parity and Caucasian ethnicity. There was significant heterogeneity across the included studies. CONCLUSIONS CVD affects a significant proportion of the population globally however there is significant heterogeneity in existing epidemiological studies.

Abstract
Venous Leg Ulcers cost Australia's healthcare system millions yearly, as they are underdiagnosed, and possibly undertreated. Most Venous Leg Ulcers are seen in general practice. However, it is currently unknown as to what treatment actions are most common in these contexts. Understanding how they are managed in these settings can improve healthcare delivery and patient outcomes. Using cross-sectional general practitioner patient encounter data collected April 2006 to March 2016 from the Bettering the Evaluation and Care of Health program, a continuous national study of general practice clinical activity in Australia, we aimed to describe the characteristics of venous leg ulcer management by general practitioners in Australia. Among the 972 100 general practitioner-patient encounters recorded, 3604 (0.34%) involved management of VLU. Male general practitioners managed Venous Leg Ulcers significantly more often than female general practitioners. Most Venous Leg Ulcers were treated via dressings (76%) and/or pharmacological treatments (25.7%), with few patients receiving the best practice treatment of medical compression (2.1%) or referral (4.9%). Patients with new (first visit) Venous Leg Ulcers were more likely to receive pharmacological treatments and to be referred elsewhere, and less likely to receive dressings than patients receiving follow-up care. There appears to be a large gap between best practice guidelines and actual Venous Leg Ulcers treatments, as referrals and appropriate treatment was low. Further longitudinal studies are needed to determine the effectiveness of care for people with Venous Leg Ulcers who are managed by general practitioners.

Abstract
AIM The purpose of the study was to compare the results of using compression knitwear and elastic bandaging in the postoperative period after endovasal laser coagulation in patients with varicose veins. PATIENTS AND METHODS A total of forty 20-to-55-year-old women with a body mass index of ≤ 35 kg/m2 and CEAP class C2-C3 lower limb varicose veins were randomized into two numerically equal groups. The Study Group included those receiving postoperative compression on the operated leg with the help an elastic stocking, whereas in the Comparison Group compression was achieved by laying an elastic bandage. Both group women underwent laser coagulation of the great saphenous vein and removal of separate veins with the help of Mueller hooks. Efficacy of compression therapy was comparatively assessed based on the results of interviewing the patients prior to intervention and 1 month thereafter, as well as by the level of pain syndrome according to the visual analogue scale at 24 and 48 postoperative hours, by the time spent by the personnel for bandaging of the limb or putting on the compression stocking intraoperatively and at the first dressing, by the degree of lower limb oedema and dynamics of regression thereof, by the area of postoperative haematoma and its dynamics after 2, 7 days and at 1 month. Besides, we evaluated the findings of ultrasonographic angioscanning of lower limb veins at one month postoperatively. RESULTS The obtained findings demonstrated that efficacy of using a medical compression stocking after the procedure of endovasal laser coagulation in women with varicose veins was comparable to that of elastic bandaging. By the incidence rate and area of extension of postoperative haematomas, degree of pain syndrome, patient-oriented assessment using the Chronic Venous Insufficiency Quality of Life Questionnaire (CIVIQ), condition of veins according to the findings of ultrasonographic angioscanning no significant differences were revealed between the two methods of elastic compression of the leg. However, using a medical stocking appeared to promote a statistically significant 1.4-1.6-fold reduction in the time spent for formation of elastic compression of the lower limb, as well as a decrease in the incidence rate and degree of local oedema of the lower limb in the postoperative period.

Barriers and enablers to the use of venous leg ulcer clinical practice guidelines in Australian primary care: A qualitative study using the theoretical domains framework. Int J Nurs Stud 2019; 103:103503.

Abstract
BACKGROUND Venous leg ulcers represent the most common chronic wound problem managed in Australian primary care. Despite the prevalence of the condition, there is an evidence-practice gap in both diagnosis and management of venous leg ulcers. OBJECTIVE We used the Theoretical Domains Framework to identify barriers and enablers perceived by primary care practitioners in implementing venous leg ulcer guidelines in clinical practice. DESIGN We collected data to explore the experiences of practice nurses and general practitioners related to their use of clinical practice guidelines in management of venous leg ulcers. SETTING(S) We recruited participants from primary care settings located in metropolitan and rural areas across Victoria, Australia. PARTICIPANTS We recruited general practitioners (15) and practice nurses (20). METHODS We conducted 35 semi-structured face-to-face and telephone interviews. Content analysis of health practitioners' statements was performed and barriers to implementing clinical practice guidelines were mapped across the Theoretical Domains Framework theoretical domains. RESULTS Six main domains from the Theoretical Domains Framework (Environmental context and resources, Knowledge, Skills, Social influences, Social/Professional Role and Identity and Belief about Capabilities) best explained these barriers and enablers. Many participants were not aware of venous leg ulcer clinical practice guidelines. Those that were aware, stated that finding and accessing guidelines was challenging and most participants relied on other sources of information. Venous leg ulcer management was greatly influenced by professional experience and suggestions from colleagues. Other barriers included busy clinical practice, absence of handheld Doppler ultrasonography, insufficient skills and a lack of confidence related to the use of technology to rule out arterial involvement prior to compression application, a particular skill related to venous leg ulcer management that will impact on healing outcomes. CONCLUSIONS We identified a number of barriers and the lack of enablers that influence the uptake of venous leg ulcer clinical practice guidelines in primary care. This paper adds a theoretically sound, systematic approach for understanding and addressing the behaviour change required to improve translation of venous leg ulcer clinical practice guidelines in clinical practice. Tweetable abstract: The need to optimise venous leg ulcer clinical practice guidelines (CPG) has never been greater as the current estimate of health cost is AUD3billion and increasing due to rising epidemics of diabetes and obesity. We found most primary care health practitioners are unaware of CPG and this will impact on health and healing outcomes in Australian primary care.

Abstract
Background: As non-cellulosic β-d-glucans are known to exert wound-healing activity by triggering keratinocytes into cellular differentiation, the functionality of a semisynthetic lichenan-based polysaccharide on skin cell physiology was investigated. Methods: γ-Propoxy-sulfo-lichenan (γ-PSL, molecular weight 52 kDa, β-1,3/1,4-p-d-Glucose, degree of substitution 0.7) was prepared from lichenan. Differentiation of primary human keratinocytes was assayed by the protein analysis of differentiation specific markers and by gene expression analysis (qPCR). The gene array gave insight into the cell signaling induced by the polysaccharide. Results: γ-PSL (1 to 100 μg/mL) triggered keratinocytes, in a concentration-dependent manner, into the terminal differentiation, as shown by the increased protein expression of cytokeratin 1 (KRT1). Time-dependent gene expression analysis proved differentiation-inducing effects, indicating strong and fast KRT1 gene expression, while KRT10 expression showed a maximum after 12 to 24 h, followed by downregulation to the basal level. Involucrin gene expression was only changed to a minor extent, which was similar to loricrin and transglutaminase. Gene array indicated the influence of γ-PSL on MAP kinase and TGF-β mediated signaling towards keratinocyte differentiation. Conclusion: The propoxylated lichenan may improve wound healing by topical application to promote the terminal barrier formation of keratinocytes.

Abstract
Chronic venous insufficiency (CVI) is responsible for significant costs to society in the form of medical and surgical treatment and, importantly, unmeasurable lost work productivity due to pain and disability. Symptomatic chronic central vein obstruction, a cause of CVI, is potentially treatable using open surgical and endovascular techniques to restore vessel patency. Although upper extremity central vein obstruction often requires an open surgical procedure for durable relief, endovascular stents have proven remarkably useful for iliofemoral disease. Containment of healthcare resources requires accurate diagnosis, durable treatment modalities, and appropriate patient selection so that therapy is targeted to those individuals most likely to benefit. In this regard, identification of appropriate lesions should be based on intravascular ultrasound and 3-dimensional imaging studies. Treatment with dedicated venous stents offers the potential for long-term symptomatic improvement and increased work productivity when used in a well-defined, anatomically appropriate population with significant, symptomatic CVI.

Abstract
BACKGROUND Chronic venous disease (CVD) is extremely common worldwide. The prevalence is increasing with age and is associated with a reduced quality of life, particularly in relation to pain, physical function and mobility. Symptomatic chronic venous insufficiency (CVI) with venous ulcer at its' endpoint, indicates interventional surgery to cure venous reflux therewith promoting wound healing and preventing recurrence. To our knowledge up to now no coherent study has been undertaken in patients with CVI who underwent an open venous surgery concerning complications, venous hemodynamics and perioperative symptomology in one study population. This was undertaken in our retrospective, single-centre, consecutive case-control study in a single patient population of a university clinic in northern Germany. Part I covers postoperative complications in relation with co-morbidities, co-medication and clinical presentation. Part II will focus on pre- and postoperative hemodynamics and evolution of symptoms. METHODS Records of n = 429 (467 extremities) patients from 2009-2013 treated with open surgery were analysed. Number and type of complication were evaluated with regards to demographic parameters, co-existing medical conditions and procedure related aspects. Complications were grouped as no events (NE), neglectable adverse events (NAE), non-neglectable adverse events (NNAE) and severe (life-threatening) adverse events (SAE). RESULTS In 467 extremities of 429 patients with CVI 130 (27,84%) postoperative complications were observed after open surgery, thereof 64 (13,7%) NAE, 66 (14,14%) NNAE and 0 SAE. 29 (6,76%) patients developed a postoperative surgical site infection, thereof 4 (0,9%) with consecutive septicaemia. Except one case with nerval lesion and paraesthesia and hypoesthesia not resolving after 12 months all complications resolved within surveillance time span of 12 months. Patients developing NAE had a higher BMI (p = 0.003), were more likely to have diabetes mellitus (p < 0.001), and co-morbidities leading to the intake of anti-platelet or anticoagulation drugs (p < 0.001). Metabolic syndrome (p < 0.001) and anti-platelet or anticoagulation (p < 0.001) could be defined as independent risk factors for the development of complications. Patients receiving open surgery of small saphenous veins had 8 times higher risk of calf muscle venous thrombosis (p = 0.001). CONCLUSION Patients with a metabolic syndrome or receiving anti-platelet therapy or anticoagulation medication should undergo open venous surgery under hospital conditions with routine postinterventional surveillance visits. Patients undergoing an open surgery of SSV are definite candidates for postoperative subcutaneous heparin thromboprophylaxis. In general stripping below knee increases the risk of postoperative sensory deficit. This resolves in almost all patients within one year.

Abstract
Venous leg ulcers (VLUs) result in substantial economic costs and reduced quality of life (QoL); however, there are few Australian cost estimates, especially using patient-level data. We measured community-setting VLU management costs and the impact on the QoL of affected individuals. VLU patients were recruited from a specialist wound clinic, an outpatient clinic, and two community care clinics in Queensland. Cost data were collected at the baseline visit. QoL (EQ-5D-5L) and wound status data were collected at baseline, 1, 3, and 6 months. Patients were classified into guideline-based/optimal care and usual care groups. Average weekly costs per patient were statistically significantly different between the usual care and optimal care groups-$214.61 and $294.72, respectively (P = 0.04). Baseline average QoL score for an unhealed ulcer was significantly higher in the optimal care group compared with usual care (P = 0.025). Time to healing differed between the usual care group and the optimal care group (P = 0.04), with averages of 3.9 and 2.7 months, respectively. These findings increase the understanding of the costs, QoL, and healing outcomes of VLU care. Higher optimal care costs may be offset by faster time to healing. This study provides data to inform an economic evaluation of guideline-based care for VLUs.

Abstract
OBJECTIVES The aim of this study was to review all published economic evaluations of guideline-based care for chronic wounds and to assess how useful these studies are for decision making in health services. METHODS Embase, PubMed, Scopus, Health Technology Assessment (HTA) and National Health Service Economic Evaluation Database (NHS EED) were searched on April 16th, 2018. We included studies that evaluated the economic impact and health outcomes associated with implementing evidence-based guidelines as a bundle of care for the prevention and/or treatment of chronic wounds. Information was extracted from each eligible study and organized by the type of chronic wound. The quality of published economic evaluation studies was assessed using the Consolidated Health Economic Evaluation Reporting Standards (CHEERS). RESULTS A total of 24 economic evaluation studies met the inclusion criteria, of which 12 applied decision analytic models. The compliance with the CHEERS checklist ranged between 43 and 83%.

Abstract
OBJECTIVE Compression stockings are the primary treatment for lipodermatosclerosis secondary to chronic venous disease, but do not improve the skin condition. The aim of this study was to investigate the impact of copper on lipodermatosclerosis. METHODS A double-blind randomised controlled pilot study was performed including patients with bilateral lipodermatosclerosis. One compression stocking of a pair was impregnated with copper. Symptom score and surface area of lipodermatosclerosis were assessed at baseline, after 2, 4 and 8 weeks. RESULTS Sixteen patients were included. There was no significant difference in mean symptom scores; however, there was a significant reduction of the surface area in the study group 42,637 to 35,739 mm2 versus 41,487 to 43,210 mm2 in the control group (p = 0.04). CONCLUSION This study demonstrates the beneficial effect of copper on lipodermatosclerosis secondary to chronic venous disease with reduction in surface area but no benefit on symptoms. Trials identification number: NCT03283800.

Abstract
On July 20, 2016, a Medicare Evidence Development and Coverage Advisory Committee panel assessed the benefits and risks of currently used lower extremity chronic venous disease (CVD) treatments and their effects on health outcome of the American adult population. The main purpose of the meeting was to advise the Centers for Medicare & Medicaid Services on coverage determination for interventions used for treatment of CVD. A systematic review of the Agency for Healthcare Research and Quality was presented, followed by lectures of invited experts and a public hearing of representatives of professional societies and the industry. After discussing critical issues, the panel voted for key questions. This report summarizes the presented evidence to support recommendations of the Society for Vascular Surgery/American Venous Forum coalition and the presentations on selected discussion topics. These included important venous disease evidence gaps that have not been sufficiently addressed, venous disease treatment disparities and how they may affect the health outcomes of Medicare beneficiaries, and mechanisms that might be supported by the Centers for Medicare & Medicaid Services to improve the evidence base to optimize the care of patients with lower extremity CVD.

Abstract
Chronic venous disease (CVD) is a common pathology, with significant physical and psychological impacts for patients and high economic costs for national healthcare systems. Throughout the last decades, several risk factors for this condition have been identified, but only recently, have the roles of inflammation and endothelial dysfunction been properly assessed. Although still incompletely understood, current knowledge of the pathophysiological mechanisms of CVD reveals several potential targets and strategies for therapeutic intervention, some of which are addressable by currently available venoactive drugs. The roles of these drugs in the clinical improvement of venous tone and contractility, reduction of edema and inflammation, as well as in improved microcirculation and venous ulcer healing have been studied extensively, with favorable results reported in the literature. Here, we aim to review these pathophysiological mechanisms and their implications regarding currently available venoactive drug therapies.

Abstract
BACKGROUND Chronic lower extremity venous disease (LECVD) is twice as prevalent as coronary heart disease, and invasive therapies to treat LECVD accounted for an estimated $290 million in Medicare expenditures in 2015. Despite increasing use of these invasive therapies, their comparative effectiveness is unknown. METHODS We conducted a systematic review and meta-analysis of treatments for patients (symptomatic and asymptomatic) with lower extremity varicosities and/or lower extremity chronic venous insufficiency/incompetence/reflux. We searched PubMed, Embase, and the Cochrane Database of Systematic Reviews for relevant English-language studies published from January 2000 to July 2016. We included comparative randomized controlled trials (RCTs) with >20 patients and observational studies with >500 patients. Short-, intermediate-, and long-term outcomes of placebo, mechanical compression therapy, and invasive therapies (surgical and endovascular) were included. Quality ratings and evidence grading was performed. Random-effects models were used to compute summary estimates of effects. RESULTS We identified a total of 57 studies representing 105,878 enrolled patients, including 53 RCTs comprised of 10,034 patients. Among the RCTs, 16 were good quality, 28 were fair quality, and 9 were poor quality. Allocation concealment, double blinding, and reporting bias were inadequately addressed in 25 of 53 (47%), 46 of 53 (87%), and 15 of 53 (28.3%), respectively. Heterogeneity in therapies, populations, and/or outcomes prohibited meta-analysis of comparisons between different endovascular therapies and between endovascular intervention and placebo/compression. Meta-analysis evaluating venous stripping plus ligation (high ligation/stripping) compared with radiofrequency ablation revealed no difference in short-term bleeding (odds ratio [OR]=0.30, 95% CI -0.16 to 5.38, P=.43) or reflux recurrence at 1-2 years (OR=0.76, 95% CI 0.37-1.55, P=.44). Meta-analysis evaluating high ligation/stripping versus endovascular laser ablation revealed no difference in long-term symptom score (OR 0.02, 95% CI -0.19 to 0.23, P=.84) or quality of life at 2 years (OR 0.06, 95% CI -0.12 to 0.25, P=.50). CONCLUSIONS The paucity of high-quality comparative effectiveness and safety data in LECVD is concerning given the overall rise in endovascular procedures. More high-quality studies are needed to determine comparative effectiveness and guide policy and practice.

Abstract
Chronic venous insufficiency and varicose veins occur commonly in affluent countries and are a socioeconomic burden. However, there remains a relative lack of knowledge about venous pathophysiology. Various theories have been suggested, yet the molecular sequence of events is poorly understood. Transforming growth factor-beta one (TGF-β1) is a highly complex polypeptide with multifunctional properties that has an active role during embryonic development, in adult organ physiology and in the pathophysiology of major diseases, including cancer and various autoimmune, fibrotic and cardiovascular diseases. Therefore, an emphasis on understanding its signaling pathways (and possible disruptions) will be an essential requirement for a better comprehension and management of specific diseases. This review aims at shedding more light on venous pathophysiology by describing the TGF-β1 structure, function, activation and signaling, and providing an overview of how this growth factor and disturbances in its signaling pathway may contribute to specific pathological processes concerning the vessel wall which, in turn, may have a role in chronic venous insufficiency.

Abstract
Abstract
Background
Leg ulceration is a feared complication of venous insufficiency. It is not known whether varicose veins predispose skin to poor wound healing. The expression pattern of gap junctional protein connexin, a known marker of poor wound healing, was investigated across various stages of venous disease.
Methods
Patients undergoing intervention for varicose veins were assessed according to the Clinical Etiologic Anatomic Pathophysiologic (CEAP) classification of varicose veins. Paired 4-mm punch biopsies were taken from above the ankle (pathological) and above the knee (control). Tissues were stained with haematoxylin and eosin, and for connexin 43, connexin 30 and connexin 26.
Results
Forty-eight paired biopsies were taken (12 each for CEAP class C0, C2, C4 and C6). The pathological skin showed progressive epithelial hyperthickening, an increase in the number and depth of rete ridges, increased inflammation and loss of dermal architecture with disease progression from C4 onwards. The overall absolute connexin expression and mean connexin expression per cell in the pathological skin similarly increased across the CEAP classes from as early as C2. Increasing levels of connexin in control skin were also noted, indicating progression of the disease proximally. Connexin 43 expression showed the strongest positive correlation between pathological and control skin.
Conclusion
Connexins were overexpressed in patients with simple varicose veins, with a stepwise increased expression through venous eczema to ulceration. Connexin 43 is a potential biomarker for venous disease. This finding suggests that varicose veins predispose skin to poor wound healing. Surgical relevanceThe overexpression of connexins, a family of gap junctional proteins, is known to cause poor healing in venous leg ulceration. It is not known whether there is any association with superficial venous disease. Here, connexin proteins were overexpressed in patients with uncomplicated varicose veins, before histological skin changes. Connexin could be a biomarker of venous disease progression.

Abstract
Stasis dermatitis commonly occurs in older age. It is caused by venous hypertension resulting from retrograde flow due to incompetent venous valves, valve destruction, or obstruction of the venous system. Further tissue changes arise from an inflammatory process mediated by metalloproteinases, which are up-regulated by ferric ion from extravasated red blood cells. Stasis dermatitis presents initially as poorly demarcated erythematous plaques of the lower legs bilaterally, classically involving the medial malleolus. It is one of the spectrum of cutaneous findings that may result from chronic venous insufficiency. Its mimics include cellulitis, contact dermatitis, and pigmented purpuric dermatoses. Duplex ultrasound is useful in demonstrating venous reflux when the clinical diagnosis of stasis dermatitis is inadequate. Conservative treatment involves the use of compression therapy directed at improving ambulatory venous pressure. Interventional therapy currently includes minimally invasive techniques such as endovenous thermal ablation and ultrasound-guided foam sclerotherapy, which have supplanted the use of open surgical techniques.

Abstract
Chronic venous disease (CVD) is a multifactorial condition representing one of the most common disorders among populations of Western countries. The heritability of about 17% suggests genetic risk factors in CVD etiology. However, so far the genetic causes are unknown. We undertook the hitherto first genome-wide association study (GWAS) for CVD, analyzing more than 1.93 M SNPs in 4,942 German individuals, followed by replication in two independent German data sets. The combined analysis of discovery and replication stages (2,269 cases and 7,765 controls) yielded robust associations within the two genes EFEMP1 and KCNH8 (rs17278665, rs727139 with P < 5 × 10−8), and suggestive association within gene SKAP2 (rs2030136 with P < 5 × 10−7). Association signals of rs17278665 and rs727139 reside in regions of low linkage disequilibrium containing no other genes. Data from the ENCODE and Roadmap Epigenomics projects show that tissue specific marks overlap with the variants. SNPs rs17278665 and rs2030136 are known eQTLs. Our study demonstrates that GWAS are a valuable tool to study the genetic component of CVD. With our approach, we identified two novel genome-wide significant susceptibility loci for this common disease. Particularly, the extracellular matrix glycoprotein EFEMP1 is promising for future functional studies due to its antagonistic role in vessel development and angiogenesis.

Abstract
This study aimed to determine the effect of low-level laser therapy (LLLT) on chronic venous leg ulcers (VLUs). A double-blinded prospective randomized controlled trial was conducted to compare incidence of complete wound closure, ulcer size and pain reduction in patients randomized to 24 treatments of placebo or LLLT (635 nm) over 12 weeks. Patients presented with a 6-week history of VLUs ranging in size from 5 to 20 cm2. Venous origin was confirmed by Doppler ultrasound and an ankle brachial index of 0.8 or greater. Of 24 patients, 23% of the test group (n = 13) and 18% of placebo group (n = 11) achieved complete wound closure. At 12 weeks, patients in test and placebo groups had a mean surface area reduction of 6.26 cm2 ( P < .0001) and 6.72 cm2 ( P < .005), respectively, and a mean pain score decrease of 43.54 points ( P < .0001) and 25.73 points ( P = .002) respectively. Differences between groups was not statistically significant for wound closure ( P = 1.0) or ulcer size ( P = .80). Mean ulcer pain was significantly reduced from initiation of treatment compared with 4 weeks’ follow-up after 12 weeks with LLLT ( P < .01). Within the limitations of the study, LLLT may not have early effects as an adjunctive therapy to wound healing of VLUs, but LLLT may have delayed effects on VLU healing and associated pain, which requires further study.

Abstract
Chronic wounds cost the Australian health system at least US$2·85 billion per year. Wound care services in Australia involve a complex mix of treatment options, health care sectors and funding mechanisms. It is clear that implementation of evidence-based wound care coincides with large health improvements and cost savings, yet the majority of Australians with chronic wounds do not receive evidence-based treatment. High initial treatment costs, inadequate reimbursement, poor financial incentives to invest in optimal care and limitations in clinical skills are major barriers to the adoption of evidence-based wound care. Enhanced education and appropriate financial incentives in primary care will improve uptake of evidence-based practice. Secondary-level wound specialty clinics to fill referral gaps in the community, boosted by appropriate credentialing, will improve access to specialist care. In order to secure funding for better services in a competitive environment, evidence of cost-effectiveness is required. Future effort to generate evidence on the cost-effectiveness of wound management interventions should provide evidence that decision makers find easy to interpret. If this happens, and it will require a large effort of health services research, it could be used to inform future policy and decision-making activities, reduce health care costs and improve patient outcomes.

Abstract
The aim of this study was to analyze the sociodemographic and clinical characteristics of people with vascular ulcers and to investigate the association between these variables. This cross-sectional, observational clinical study was conducted in outpatient clinics from February to August 2009. Interview, clinical exam, Pressure Ulcer Scale Healing and photographic registry of the wounds were performed. Forty-two individuals participated who were, on average, 60 (± 12) years old, 73.8% males, with single wounds (66.7%) resulting from alterations in venous circulation (90.5%). Their wounds had lasted for up to one year (55.5%). There was an association between the PUSH score (p=0.019) and depth of wound (p=0.027) with currently performing occupational activity, as well as between history of tobacco use and gender (p=0.049). The sociodemographic characteristics that were observed were similar to the others, except for being male, which indicates the need for more studies in the population in Goiânia, Brazil.

Abstract
AIMS Extracellular matrix remodelling has been implicated in a number of vascular conditions, including venous hypertension and varicose veins. However, to date, no systematic analysis of matrix remodelling in human veins has been performed. METHODS AND RESULTS To understand the consequences of venous hypertension, normal and varicose veins were evaluated using proteomics approaches targeting the extracellular matrix. Varicose saphenous veins removed during phlebectomy and normal saphenous veins obtained during coronary artery bypass surgery were collected for proteomics analysis. Extracellular matrix proteins were enriched from venous tissues. The proteomics analysis revealed the presence of >150 extracellular matrix proteins, of which 48 had not been previously detected in venous tissue. Extracellular matrix remodelling in varicose veins was characterized by a loss of aggrecan and several small leucine-rich proteoglycans and a compensatory increase in collagen I and laminins. Gene expression analysis of the same tissues suggested that the remodelling process associated with venous hypertension predominantly occurs at the protein rather than the transcript level. The loss of aggrecan in varicose veins was paralleled by a reduced expression of aggrecanases. Chymase and tryptase β1 were among the up-regulated proteases. The effect of these serine proteases on the venous extracellular matrix was further explored by incubating normal saphenous veins with recombinant enzymes. Proteomics analysis revealed extensive extracellular matrix degradation after digestion with tryptase β1. In comparison, chymase was less potent and degraded predominantly basement membrane-associated proteins. CONCLUSION The present proteomics study provides unprecedented insights into the expression and degradation of structural and regulatory components of the vascular extracellular matrix in varicosis.

Abstract
OBJECTIVES Determine whether general practitioners have sufficient expertise in the field of leg ulcers. METHOD A cross-sectional survey was conducted among 179 general practitioners working in the region Île-de-France to evaluate the implementation of leg ulcer guidelines issued by the Superior Health Authority (HAS) in 2006. Participating physicians were either internship supervisors or practitioners in Paris' 14th district. RESULTS The first hundred usable answers (response rate 65%) came from 71 internship supervisors and 29 practitioners of Paris' 14th district. Only 40% of the physicians were aware of the guidelines, with no significant difference noted between the two groups. 9/10 practitioners examined less than 10 patients with leg ulcers per year. Physical examinations were done according to the guidelines and a venous Doppler was prescribed in two thirds of the cases. The ankle-brachial pressure index (ABPI) essential to diagnose lower limb arteriopathy was measured for only 10% of the patients. In accordance with the guidelines, compression was by far (73%) considered as the main treatment as compared to dressing (37%), but compression therapy was well prescribed in only one-third of the cases. Despite poor prognosis criteria (characteristic and time course), referral for a specialized opinion was rare. CONCLUSION Even if they were not always aware of the detailed guidelines, the practitioners applied the main recommendations. Nevertheless, practices could be improved by measuring the ABPI, searching for a diagnosis of arteriopathy, and better prescription of compression therapy. General practitioners should refer patients with leg ulcers to a specialized hospital unit.

Symptoms in patients with skin changes due to chronic venous insufficiency often lead to emergency care service: an Italian observational study. Int Wound J 2015; 13:967-71.

Abstract
Chronic venous insufficiency (CVI) is the most advanced form of chronic venous disease (CVD), and is often associated with skin changes such as hyperpigmentation, eczema, lipodermatosclerosis and venous skin ulceration that cause discomfort, pain, sleep disturbances, absenteeism in the workplace, disability and deteriorated quality of life (QoL). The purpose of this study is to evaluate the prevalence of CVI and skin changes in patients who turn to Continuous Assistance Services due to the presence of disturbing symptoms of their condition. Data were evaluated by consulting the medical records, during a 16-month period, available with three Continuous Assistance Services of the Italian territory. The overall population of the referring centres consisted of 1186 patients [739 females (62·31%) and 447 males (37·69%)]. Seventy-nine patients (6·66%) consulted the emergency unit for venous symptoms related to CVD. Patients with more severe disease (CVI, categories C4-C6) represented the majority accounting for 60·75%, while patients with moderate disease (C3) accounted for 35·44% and patients with mild disease (C1-C2 stages) accounted for 3·79%. The main finding of this study is that despite CVI not being a disease that commonly requires medical emergency/urgency intervention, patients with CVI, especially in advanced stage with skin changes, may turn to Continuous Assistance Service for treating bothersome symptoms related to their condition.

Abstract
Venous leg ulceration (VLU) is one of the most predominate medical disorders worldwide and in the western hemisphere it affects around 1.5% of the general population and up to 5% of the elderly population. Unfortunately, this trend will only increase given the growth of an aging population worldwide. Understanding its pathophysiology that begins with venous hemodynamic abnormalities and leads to inflammatory alterations with microcirculatory changes is critical to delivering effective curative therapy. As such, the main component to treatment is reversing the underlying venous hypertension and pro-inflammatory milieu using compression treatment along with various adjuvant therapies. Given its impact, a comprehensive multi-pronged approach to care, treatment and prevention is required to reverse the increasing trend that is observed worldwide.

Abstract
OBJECTIVE To test the hypothesis that patients with soft tissue changes related to superficial venous insufficiency (SVI) have greater benefits from treatment than those with only symptomatic varicose veins. BACKGROUND A commonly held view is that SVI is only a minor ailment, yet randomized clinical trials (RCTs) show that treatment improves quality of life (QoL) and is cost-effective. In an effort to curb the treatment costs of this common disorder, rationing is applied in many health care systems, often limiting the reimbursement of treatment to those with soft tissue changes. METHODS This cohort study draws its data from an interventional RCT. After informed consent, consecutive patients with symptomatic unilateral SVI were randomized to receive surgical ligation and stripping or endovenous laser ablation. This analysis differentially studies the outcomes of patients with simple varicose veins (C2: n = 191) and soft tissue complications (C3-4: n = 76). Effectiveness outcomes measured up to 1 year included the following: Qol [short form 36 (SF36), EuroQol, and the Aberdeen Varicose Veins Questionnaire], clinical recurrence, and the need for secondary procedures. Multivariable regression analysis was used to control for potential confounding factors. RESULTS Both groups saw significant improvements in QoL. All improvements were equal between groups apart from the SF36 domain of Bodily Pain, where C2 saw an improvement of 12.8 [95% confidence interval (CI): 4.8-20.8] points over C3-4 participants (P = 0.002), who also suffered more recurrence [odds ratio (OR) = 2.7, 95% CI: 1.2-6.1, P = 0.022] and required more secondary procedures (OR = 4.4, 95% CI: 1.2-16.3, P = 0.028). CONCLUSIONS This study suggests that rationing by clinical severity contradicts the evidence. Delaying treatment until the development of skin damage leads to a degree of irreversible morbidity and greater recurrence. TRIAL REGISTRATION NCT00759434 Clinicaltrials.gov.

Abstract
Prevention, management, and treatment of venous thromboembolism requires understanding
of the epidemiology and associated risk factors, particularly in recognizing populations warranting
prophylaxis, in evaluating patients with high risk situations, and in determining the duration of
anticoagulation required to minimize recurrent thrombosis and to avoid postthrombotic
syndrome. The present paper reviews recent advances concerning acquired and genetic risk factors for
venous thrombosis, analyses individual risks related to age, and focuses on thrombotic genetic risk
factors and the synergistic gene-environment and gene-gene interactions and their importance in
the management and treatment of venous thromboembolic disease.

Abstract
Chronic venous leg ulcers (VLU) affect around 1% of the adult population in the Western world. The impact of VLU is both social and economic, with significant expenditures on active venous ulcers to provide medical treatment and eventual healing. At the core of VLU is venous hypertension which affects the venous macrocirculation. The changes incurred in venous hemodynamics leads to microcirculatory changes affecting the postcapillary venule and surrounding tissues. Inflammation by leukocytes affecting the venous endothelium, promotes a complex cascade and activation of adhesion molecules expression, chemokines and cytokines released, altered growth factor responses, and activation of protease (e.g. tPA) and proteinase (e.g. MMPs) activity that causes dysregulation and compromise of tissue integrity with eventual dermal damage and ulcer development. A critical component to treating VLU is correcting the abnormal venous hemodynamics and compression therapy. Unfortunately, VLU recurrence ranges between 30–70%, and other modalities in therapy along with compression are required. The goal for adjuvant products is to restore the balance from an inflammatory chronic wound to that of a reparative wound that will promote provisional matrix and epithelialization. There are many products on the market that can be used as adjuvant to compression therapy, but it must be recognized that there is a paucity of clinical trials that have evaluated the clinical effectiveness of specific products with clearly defined end points, and most importantly a healed VLU with a low recurrence rate. This review will discuss the fundamentals of VLU inflammation, and evaluate the available literature that may have benefit in reducing inflammation and lead to effective VLU healing.

Abstract
BACKGROUND Venous leg ulcers represent the worst extreme within the spectrum of chronic venous disease. Affecting up to 3% of the adult population, this typically chronic, recurring condition significantly impairs quality of life, and its treatment places a heavy financial burden upon healthcare systems. The current mainstay of treatment for venous leg ulcers is compression therapy, which has been shown to enhance ulcer healing rates. Open surgery on the veins in the leg has been shown to reduce ulcer recurrence rates, but it is an unpopular option and many patients are unsuitable. The efficacy of the newer, minimally-invasive endovenous thermal techniques has been established in uncomplicated superficial venous disease, and these techniques are now beginning to be used in the management of venous ulceration, though the evidence for this treatment is currently unclear. It is hypothesised that, when used with compression, ablation may further reduce pressures in the leg veins, resulting in improved rates of healing. Furthermore, since long-term patient concordance with compression is relatively poor, it may prove more popular, effective and cost-effective to provide a single intervention to reduce recurrence, rather than life-long treatment with compression. OBJECTIVES To determine the effects of superficial endovenous thermal ablation on the healing, recurrence and quality of life of people with active or healed venous ulcers. SEARCH METHODS In August 2013 we searched Cochrane Wounds Group Specialised Register; The Cochrane Central Register of Controlled Trials (CENTRAL) (The Cochrane Library); Ovid MEDLINE; Ovid MEDLINE (In-Process & Other Non-Indexed Citations); Ovid EMBASE; and EBSCO CINAHL. There were no restrictions on the language of publication but there was a date restriction based on the fact that superficial endovenous thermal ablation is a comparatively new medical technology. SELECTION CRITERIA Randomised clinical trials comparing endovenous thermal ablative techniques with compression therapy alone for venous leg ulcers were eligible for inclusion. Trials had to report on at least one objective measure of ulcer healing (primary outcome) such as proportion of ulcers healed at a given time point, time to complete healing, change in ulcer size, proportion of ulcers recurring over a given time period, or at a specific point, and ulcer-free days. Secondary outcomes sought included patient-reported quality of life, economic data and adverse events. DATA COLLECTION AND ANALYSIS Details of potentially eligible studies were extracted and summarised using a data extraction table. Data extraction and validity assessment were performed independently by two review authors, and any disagreements resolved by consensus or by arbitration of a third review author. MAIN RESULTS No eligible randomised controlled trials were identified. There is an absence of evidence regarding the effects of superficial endovenous thermal ablation on ulcer healing, recurrence or quality of life of people with venous leg ulcer disease. AUTHORS' CONCLUSIONS The review identified no randomised controlled trials on the effects on ulcer healing, recurrence or quality of life, of superficial endovenous thermal ablation in people with active or healed venous leg ulcers. Adequately-powered, high quality randomised controlled trials comparing endovenous thermal ablative interventions with compression therapy are urgently required to explore this new treatment strategy. These should measure and report outcomes that include time to ulcer healing, ulcer recurrence, quality of life and cost-effectiveness.
