Abstract
This article aims to review the scarce available evidence on the effectiveness of the Well Leg Programme within the Lindsay Leg Clubs in terms of preventing wound recurrence and improving members' wellbeing. It collates the numerical data on members' wounds and healing rates from the Lindsay Leg Club relational database and members' narratives from a qualitative service evaluation of the Lindsay Leg Clubs. Findings of the review suggest that remaining within the Well Leg regime for several months (or longer) after having had a healed ulcer seems to provide further opportunity to prevent recurrence, and may also provide non-clinical benefits, such as improved wellbeing. Based on the review of available published evidence into the effectiveness of the Well Leg regime, we conclude that there is scope for further studies, including a comparison with other existing treatment and prevention protocols.

Abstract
OBJECTIVE To evaluate the healing outcomes and costs associated with the aetiological management of venous leg ulcers (VLUs) treated with recommended multicomponent bandages (MCBs) and short-stretch bandages (SSBs). METHOD This observational study is a retrospective comparative study (Level 2b), based on the French administrative healthcare database (Système National des Données de Santé, SNDS). It includes patients treated from onset with reimbursed MCBs and SSBs for a VLU episode, between July 2018 and September 2020. Although other compression systems, such as long-stretch bandages, are commonly used for the treatment of VLUs, they are not recommended by health authorities in France and thus, were not considered for this study. A binomial regression model was performed to estimate the adjusted relative risk of wound closure rates at three months for each group, based on potential confounding factors including, notably, age, sex, key comorbidities, and wound dressing size. The mean healthcare cost was calculated for patients whose VLUs healed within the study period. RESULTS The reimbursement data (including prescribed compression systems and nursing care) of the 25,255 selected patients were analysed in the study. There were no significant differences between the MCBs and SSBs groups when considering patient characteristics. The healing rates after three months' treatment, were 42% and 35% (p<0.001) in the MCBs and SSBs groups, respectively. When adjusting the statistical model, the chance of healing at three months was still 12% higher with MCBs compared with SSBs (p<0.0001). The median healing time was estimated at 115 (interquartile range (IQR): 60-253) days in the MCB group versus 137 (IQR: 68-300) days in the SSBs group. The average treatment cost per patient with a healed ulcer was €2875±3647 in the MCB group and €3580±5575) in the SSBs group (p=0.0179), due to lower hospital stay and nursing costs in the MCB group. Differences in wound characteristics between the two groups cannot be totally excluded, due to the limited content of the database in terms of clinical data, but should have been addressed, to some extent, through the study selection criteria and the chosen regression model. CONCLUSION In this study, this SNDS analysis seemed to confirm that the healing outcomes achieved in real-life with MCBs were in line with those reported in clinical trials, and superior to SSBs, which reinforces the current position from the guidelines.

Abstract
OBJECTIVE Leg ulcers are common, distressing and painful for patients, and are a significant financial burden to healthcare providers. Compression therapy is the mainstay of treatment for venous leg ulceration. Several studies have evaluated leg ulcer management and compression therapy in the community. However, little is known about the prevalence of leg ulceration and use of compression therapy in acute hospitals. The aim of this study was to explore the published literature on the use of compression therapy for inpatients with leg ulcers in UK National Health Service hospital settings. METHOD A literature search was undertaken to identify published papers reporting on inpatient leg ulcer populations and the use of compression therapy in hospitals using the following databases: CINAHL, MEDLINE Complete, Embase and PubMed. RESULTS The literature review identified 364 articles, of which three met the eligibility criteria. These studies reported on the prevalence of leg ulceration, the number of Doppler assessments conducted for patients and the use of compression therapy. CONCLUSION This review confirmed a lack of information on the prevalence of hospital inpatients with leg ulcers, and identified the need to conduct prevalence audits, establish leg ulcer services to streamline inpatient leg ulcer care and provide staff and patient education programmes.

Abstract
OBJECTIVE To investigate whether the use of a simple baseline measurement predicts venous leg ulcer healing at 12 and 24 weeks. METHOD This was a secondary analysis of a cohort of four randomised controlled trials (RCTs) of treatments adjuvant to compression. Self-reported ulcer duration, and measured ulcer length and width, to calculate estimated ulcer area, were used to obtain a Margolis index score. The score created three prognostic strata for likelihood to heal within 24 weeks, and the number of participants healed and time-to-healing were compared. RESULTS There were a total of 802 participants across the four RCTs-408 (50.9%) in two 12-week trials and 394 (49.1%) in two 24-week trials. The mean age of participants was 63.7±17.6 years, and 372 were female (46.4%). The Margolis index score at baseline was 0 for 320 participants (predicted normal healing); 1 for 334 participants; and 2 for 148 participants (both 1 and 2 predicted slow-to-heal). Overall, 248 (77.5%) of those participants who scored 0 at baseline healed within 24 weeks, compared with 182 (54.5%) of participants who scored 1, and 30 (20.3%) participants who scored 2. The median time-to-healing was 40 (24-62) days, 57 (35-100) days and 86.5 (56-151) days, respectively. The area under the receiver operating characteristic curve was 0.69 and 0.77, respectively, for the 12 and 24 week trials. CONCLUSION A simple baseline index identifies participants with normal or slow-to-heal wounds and could be used to demonstrate prognostic balance between treatment groups in trials. This approach could also be used in clinical practice to assist with managing expectations and for early identification of patients who may best benefit from adjuvant treatments.

Abstract
This study aimed to compare mobility range, level of pain and sleep quality in patients with venous leg ulcers to age- and gender-matched controls without ulcers. Twenty patients with venous leg ulceration and 20 matched controls each answered a questionnaire, completed the short-physical performance battery, filled in a subject diary and wore a smartwatch for 1 week. The median daily step counts of the ulcer group (3622 steps/day) and the control group (5133 steps/day) were significantly different (P = .017). Significant correlations between total step count and age, duration of physical outdoor activities and scores in the short-physical performance battery were observed in the ulcer group. The scores in the short-physical performance battery were significantly different in both groups (P = .005), indicating weaker physical performance in the ulcer group. The greatest difference in the self-reported level of pain between the two groups was stated during movement. On average, the ulcer group slept shorter by 1 h 38 min (P = .002) and had 0.7 wake phases per night (P = .019) more than the control group. Assessing mobility in patients with venous leg ulcers can be used to develop preventive and interventional concepts to improve and individualise physical therapies.

Abstract
Hard-to-heal or recurrent leg ulcers can have multiple aetiologies. One of these is incompetent veins. The main focus of this article is to discuss the common treatment for venous leg ulcers with the use of sclerotherapy. This simple surgical procedure obliterates smaller veins and telangiectasia. Veins with larger diameters (varicosities) can be treated with ablation therapy. The intent of sclerosis or ablation therapy is to destroy the incompetent veins and allow the collateral circulation to improve venous return, decreasing venous hypertension, which then enhances skin closure, wound healing and the resolution of the ulcer.

Abstract
OBJECTIVE Venous leg ulcers (VLUs) are both chronic and recurrent. The treatment of such ulcers often require multiple outpatient visits and dressing changes. Several reports on the costs of treating such VLUs have been reported in the west. We prospectively evaluated the clinical and economic burden of VLUs in a population of Asian patients in the tropics. METHODS Patients from a prospective two-center study conducted at two tertiary hospitals in Singapore, as a part of the Wound Care Innovation in the Tropics program, between August 2018 and September 2021 were recruited. The patients were followed up for 12 weeks (visit 1 to visit 12), until index ulcer healing, death, or lost to follow-up (whichever came first). These patients were then followed up 12 weeks later to determine the longer term outcome of the wound (healed, recurrence, remained unhealed). The itemized costs derived from the medical service were retrieved from the relevant departments of the study sites. The patients' health-related quality of life was assessed at baseline and the last visit of the 12-week follow-up period (or until index ulcer healing), using the official Singapore version of the EuroQol five-dimension-5L questionnaire, which also includes a visual analog scale (EQ-VAS). RESULTS A total of 116 patients were enrolled; 63% were men, and the mean patient age was 64.7 years. Of the 116 patients, 85 (73%) had a healed ulcer at 24 weeks (mean duration to ulcer healing, 49 days), and 11 (12.9%) had experienced ulcer recurrence within the study period. Within the 6-month follow-up period, the mean direct healthcare cost per patient was USD$1998. The patients with healed ulcers had significantly lower costs per patient compared with those with unhealed ulcers (USD$1713 vs USD$2780). Regarding health-related quality of life, 71% of the patients had a lower quality of life at baseline, which had improved at 12 weeks of follow-up, with only 58% of the patients reported to have a lower quality of life. Also, the patients with healed ulcers scored higher for both utilities (societal preference weights) and EQ-VAS at follow-up (P < .001). In contrast, patients with unhealed ulcers only scored higher EQ-VAS at follow-up (P = .003). CONCLUSIONS The findings from this exploratory study provide information on the clinical, quality of life, and economic burden of VLUs in an Asian population and suggest the importance of healing VLUs to reduce the effects on patients. The present study provides data as a basis for economic evaluation as a consideration for the treatment of VLUs.

Abstract
Exercise is recommended as an adjunct treatment, alongside compression therapy to increase venous leg ulcer (VLU) wound healing times, however, there are no published programmes available that support patients to exercise at home on their own. To develop an exercise-based lifestyle intervention that is feasible and acceptable to people with VLUs, a participatory approach was utilised. Clinicians, researchers, and people living with VLUs collaborated in the design of "FISCU Home". Two focus groups and nine interviews were conducted with people living with a VLU. Tissue viability nurses provided clinical expertise. Data was analysed through thematic analysis. Ten key themes were identified and incorporated into FISCU Home: (I) a condition-specific flexible programme, (II) personal assessment and tailored exercises, (III) tapered individualised support, (IV) short lower-intensity sessions, (V) chair-based options, (VI) falls prevention, (VII) accessible resources, (VIII) functional, compact, self-managed exercises, (IX) a behaviour change strategy, and (X) education. FISCU Home has integrated patients' needs and preferences with evidence-based principles and theory to create an exercise-based lifestyle intervention for people with VLUs. FISCU Home could provide a mainstream adjunct therapy in wound care and support the movement towards self-management.

Abstract
Leg ulcers caused by impaired venous blood return are the most typical chronic wound form and have a significant negative impact on the lives of people living with these wounds. Thus, it is important to provide early assessment and appropriate treatment of the wounds to promote their healing in the normal trajectory. Gathering quality wound data is an important component of good clinical care, enabling monitoring of healing progress. This data can also be useful to train machine learning algorithms with a view to predicting healing. Unfortunately, a high volume of good-quality data is needed to create datasets of suitable volume from people with wounds. In order to improve the process of gathering venous leg ulcer (VLU) data we propose the generative adversarial network based on StyleGAN architecture to synthesize new images from original samples. We utilized a dataset that was manually collected as part of a longitudinal observational study of VLUs and successfully synthesized new samples. These synthesized samples were validated by two clinicians. In future work, we plan to further process these new samples to train a fully automated neural network for ulcer segmentation.

Abstract
BACKGROUND Approximately 20% of patients with chronic limb-threatening ischemia have no revascularization options, leading to above-ankle amputation. Transcatheter arterialization of the deep veins is a percutaneous approach that creates an artery-to-vein connection for delivery of oxygenated blood by means of the venous system to the ischemic foot to prevent amputation. METHODS We conducted a prospective, single-group, multicenter study to evaluate the effect of transcatheter arterialization of the deep veins in patients with nonhealing ulcers and no surgical or endovascular revascularization treatment options. The composite primary end point was amputation-free survival (defined as freedom from above-ankle amputation or death from any cause) at 6 months, as compared with a performance goal of 54%. Secondary end points included limb salvage, wound healing, and technical success of the procedure. RESULTS We enrolled 105 patients who had chronic limb-threatening ischemia and were of a median age of 70 years (interquartile range, 38 to 89). Of the patients enrolled, 33 (31.4%) were women and 45 (42.8%) were Black, Hispanic, or Latino. Transcatheter arterialization of the deep veins was performed successfully in 104 patients (99.0%). At 6 months, 66.1% of the patients had amputation-free survival. According to Bayesian analysis, the posterior probability that amputation-free survival at 6 months exceeded a performance goal of 54% was 0.993, which exceeded the prespecified threshold of 0.977. Limb salvage (avoidance of above-ankle amputation) was attained in 67 patients (76.0% by Kaplan-Meier analysis). Wounds were completely healed in 16 of 63 patients (25%) and were in the process of healing in 32 of 63 patients (51%). No unanticipated device-related adverse events were reported. CONCLUSIONS We found that transcatheter arterialization of the deep veins was safe and could be performed successfully in patients with chronic limb-threatening ischemia and no conventional surgical or endovascular revascularization treatment options.

Abstract
OBJECTIVE To assess the clinical outcomes and cost-effectiveness of using a two-layer cohesive compression bandage (TLCCB; Coban 2, 3M, US) compared with a two-layer compression system (TLCS; KTwo, Urgo, France) and a cohesive inelastic bandage system (CIBR; Actico, L&R, Germany) in treating newly diagnosed venous leg ulcers (VLUs) in clinical practice, from the perspective of the UK's National Health Service (NHS). METHOD This was a modelling study based on a retrospective cohort analysis of the case records of patients with a newly diagnosed VLU randomly extracted from the The Health Improvement Network (THIN) database who were treated with TLCCB, TLCS or CIBR. No significant differences were detected between the groups. Nevertheless, analysis of covariance was performed to enable differences in patients' outcomes between the groups to be adjusted for any heterogeneity in baseline covariates. Clinical outcomes and cost-effectiveness of the alternative compression systems were estimated over 12 months after starting treatment. RESULTS There were 250 patients in each group. Time from wound onset to starting compression was a mean of two months. The healing distribution of the TLCCB-treated patients was significantly different from that of the other two cohorts (p=0.003); the probability of healing at 12 months was 0.62, 0.51 and 0.49 in the TLCCB, TLCS and CIBR groups, respectively. Patients treated with TLCCB experienced better health-related quality of life (HRQoL) over 12 months (0.86 quality-adjusted life years (QALYs) per patient), compared with those treated with TLCS and CIBR (0.83 and 0.82 QALYs per patient, respectively). The 12-month NHS wound management cost was £3693, £4451 and £4399 per patient in the TLCCB, TLCS and CIBR groups, respectively. CONCLUSION Within the model's limitations, treating newly diagnosed VLUs with TLCCB instead of the other two compression systems appears to afford a more cost-effective use of NHS-funded resources in clinical practice, since it is expected to result in increased healing, better HRQoL and a lower wound management cost for the NHS.

Abstract
OBJECTIVE Venous leg ulcer (VLU) is a chronic disease and has periods of exacerbation and remission. Various bandage systems-single-layered, double-layered and multiple-layered with elastic and non-elastic components-have been developed. The requirement for sustained pressure brought about the introduction of the four-layer bandage. We studied the bacteriology of VLUs and the effect of four-layer bandages on their healing. METHOD Clinical details of all patients, with wound size measurement by gauze piece, wax paper and scale, were recorded. The wounds were initially debrided and photographic records of all patients were maintained. Patients were followed up every week, when the dressings and four-layer bandages were changed. RESULTS A total of 60 patients were recruited to the study with four patients having bilateral disease and so a total of 64 VLUs were evaluated. Of these, 60 (93.8%) healed completely, one (1.6%) healed partially and three (4.7%) did not heal. After excluding the four VLUs that did not fully heal, 10 (16.7%) had recurrence while 50 (83.3%) had no recurrence in the follow-up period, which lasted for one year. During the first visit (baseline), meticillin-resistant Staphylococcus aureus (MRSA) was isolated in 29 (45.31%) VLUs and Pseudomonas spp. in 20 (31.25%) VLUs. With subsequent dressing, the VLU size decreased and the culture of the VLU was sterile from the third culture onwards in 45 cases. There was a significant correlation (p<0.001) between VLU size and the number of dressings. CONCLUSION Compression therapy is the mainstay of treatment of VLU, with rapid healing and improvement in bacteriological profile. Compression in the range of 30-40mmHg is the most effective treatment for uncomplicated VLUs with adequate arterial competency.

Abstract
BACKGROUND The level of personal health literacy of patients with venous leg ulcers is likely to affect their ability to self-manage their condition impacting on their adherence to treatment and influences healing and recovery outcomes. OBJECTIVES To scope existing research that examined the level of health literacy in venous leg ulcer patients, to identify how this may link to self-management behaviours (particularly physical activity and compression adherence), and venous leg ulcer healing outcomes. METHODS This scoping review was based on the PRISMA-ScR six-stage framework. We searched MEDLINE, EMBASE, the Cochrane Library, PsycInfo and Health, Open Grey, and Google Scholar for publications examining general and specific health literacy in those with venous leg ulcers and for those examining any potential links of health literacy with self-management/healing generally, published between 2000-2020. This search was guided by a published protocol; studies that described other types of ulcers or did not examine health literacy were excluded. After applying inclusion and exclusion criteria the initial search identified 660 articles. RESULTS We included five articles. Four studies used randomised controlled trials or experimental designs to test the effect of specific health literacy interventions on venous leg ulcer knowledge, compression therapy use, or healing outcomes. One study was a cross- sectional survey with qualitative elements, assessing health literacy in venous leg ulcer patients. Broadly, the research suggested that health literacy was suboptimal amongst those with venous leg ulcers, and health literacy interventions had limited effects on improving key venous leg ulcer specific outcomes. CONCLUSION This review provides a synthesis of extant literature examining health literacy in patients with venous leg ulcers. We identified a dearth of literature investigating the value of general and specific health literacy interventions in this space. Most importantly, no recent research on general health literacy and venous leg ulcers was identified, despite strong theoretical utility to do so. The few studies identified largely indicated that targeting health literacy of patients with venous leg ulcers is a viable area of research and intervention, encouraging future researchers and clinicians to consider patient health literacy in venous leg ulcer management.

Abstract
BACKGROUND Chronic wounds are a serious public health problem worldwide. Providing optimal treatment to patients suffering from leg ulcers is a priority for nursing. Therefore, nursing students need to acquire the necessary competencies to provide evidence-based care. Augmented Reality (AR) is an emerging technology in health science education which can help nursing students achieve these skills if it is promoted by both institutions and educationalists. OBJECTIVES To test the effectiveness of an AR-based methodology for teaching-learning aspects of the nursing curriculum (leg ulcer care), as well as to describe how AR influences different learning determinants of nursing students. DESIGN A quasi-experimental study was carried out. PARTICIPANTS/SETTINGS The participants of the study were 137 s-year nursing students from the School of Nursing of the University of Santiago de Compostela (Spain) (average age = 21.59 years, 80.29 % females). Of them, 65 comprised the control group (Non-AR-based teaching) and 72 comprised the experimental group (AR-based teaching). METHODS Pre-post tests were used to measure knowledge and skills about leg ulcer care in both groups. Additionally, two validated questionnaires were selected to identify the influence of AR on learning determinants in the experimental group. The study took place during the 2018/2019 academic year. RESULTS Significantly higher scores (7.68 vs. 6.14) were found in the knowledge post-test in the experimental group (p ≤ 0.001), while the pre-test did not show differences between groups (4.43 vs. 4.32). Also, nursing students indicated high scores in attention, autonomous learning, understanding and motivation to carry out learning objectives using AR. CONCLUSIONS AR is a tool that improves performance related to the specific aspects of the nursing academic curriculum (leg ulcer care), while encouraging positive attitudes towards the teaching-learning process. These findings reinforce the need to include innovative methodologies in nursing classrooms.

Abstract
Chronic peripheral oedema is a common long-term condition, with conflicting evidence on how it is best managed. It is crucial to establish the cause of the oedema to decide on the most appropriate intervention for its management. If the oedema is not managed, it can lead to unwanted complications for the service user. The District Nurse (DN) is pivotal in the management of patients with long-term conditions, both directly and indirectly. It is important that a multi-disciplinary approach is used, although nurses are now more autonomous due to advances in practice. The present study focuses on leg elevation as a form of intervention in the treatment of chronic peripheral oedema. As with any intervention, there are some risks with leg elevation that must be considered. This should be disseminated and monitored effectively.

PLoS One 2022; 17:e0274023. [PMID: 36107964 PMCID: PMC9477261 DOI: 10.1371/journal.pone.0274023] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/19/2022] [Accepted: 08/19/2022] [Indexed: 11/18/2022] Open
Abstract
The main objectives of the study were to explore whether laser Photobiomodulation (PBM) in addition to traditional dressing of hard-to-heal venous leg ulcer, reduced healing time of the ulcer and if the duration of the ulcer before PBM impacted the treatment time with PBM to healing. The intervention group was frail, elderly patients with home healthcare in the municipality of Skellefteå, registered in the Swedish quality registry RiksSar for ulcer treatment with hard-to-heal venous leg ulcer. The control group with equivalent physical conditions was obtained from the same quality registry. Definition of hard-to-heal ulcer was six weeks duration or more. The PBM was performed two times per week with laser type infrared GaAs, 904nm, 60mW, and 700Hz, targeting lymphatic area and ulcer area. Laser type red visible, GaAllnp, 635nm, 75mW and 250Hz, targeting ulcer area. The intervention group treated with PBM in addition to traditional dressing healed significantly faster than the control group with a mean of 123 days (p = 0.0001). Duration of the ulcer before PBM did not impact the healing time. To conclude, the findings indicate that using PBM in addition to dressing may have multiple benefits on hard-to-heal venous leg ulcer, saving valuable time and resources for patients, healthcare providers, and institutions.

Abstract
OBJECTIVES To investigate factors that promote and prevent the use of compression therapy in people with venous leg ulcers. DESIGN Qualitative interview study with nurses using the Theoretical Domains Framework (TDF). SETTING Three National Health Service Trusts in England. PARTICIPANTS Purposive sample of 15 nurses delivering wound care. RESULTS Nurses described factors which made provision of compression therapy challenging. Organisational barriers (TDF domains environmental context and resources/knowledge, skills/behavioural regulation) included heavy/increasing caseloads; lack of knowledge/skills and the provision of training; and prescribing issues (variations in bandaging systems/whether nurses could prescribe). Absence of specialist leg ulcer services to refer patients into was perceived as a barrier to providing optimal care by some community-based nurses. Compression use was perceived to be facilitated by clinics for timely initial assessment; continuity of staff and good liaison between vascular/leg ulcer clinics and community teams; clear local policies and care pathways; and opportunities for training such as 'shadowing' in vascular/leg ulcer clinics. Patient engagement barriers (TDF domains goals/beliefs about consequences) focused on getting patients 'on board' with compression, and supporting them in using it. Clear explanations were seen as key in promoting compression use. CONCLUSIONS Rising workload pressures present significant challenges to enhancing leg ulcer services. There may be opportunities to develop facilitated approaches to enable community nursing teams to make changes to practice, enhancing quality of patient care. The majority of venous leg ulcers could be managed in the community without referral to specialist community services if issues relating to workloads/skills/training are addressed. Barriers to promoting compression use could also be targeted, for example, through the development of clear patient information leaflets. While the patient engagement barriers may be easier/quicker to address than organisational barriers, unless organisational barriers are addressed it seems unlikely that all people who would benefit from compression therapy will receive it.

Abstract
AIM To explore the service provision for compression therapy for inpatients with leg ulcers in UK hospitals. METHODS An online survey was carried out to explore the service provision in hospital settings. It was distributed to Wounds UK National Conference delegates and to wound care specialist groups using social media. RESULTS The authors received 101 responses from health professionals in the UK. Of these, 67.3% reported there was no dedicated service for inpatients with leg ulceration and only 32% said compression therapy was provided in their hospitals. CONCLUSION This survey confirmed there is a significant shortfall in care provision for patients with leg ulcers in secondary care and highlighted the wide variations in service delivery in hospitals. Further research is needed to understand the reasons for these variations.

Abstract
PURPOSE OF THE STUDY Population aging is connected with an increased incidence of chronic diseases. A common related problem is chronic skin ulcers, which, while not life-threatening, can significantly decrease the quality of the patient's life. The present study aims to evaluate new materials and methods to improve and accelerate the treatment of leg ulcers. MATERIAL AND METHODS Twenty-five patients with chronic ulcers treated using autologous growth factors applied on a nanofiber carrier were included in the cohort. The control group consisted of 15 patients treated using standard moist wound therapy. The surface area of the ulcer was measured on the 0th, 14th, 28th, 56th, 84th, 112th, 140th, 140th, and 168th day of treatment. Ulcer depth was measured on the 0th, 5th, 28th, 84th, and 168th day of treatment. Results were statistically processed and evaluated. RESULTS During the study, the defect area decreased in both the control and experimental group. Statistically significantly better results were observed in the experimental group relative to the progress of ulcer depth. The experimental group also had more healed ulcers. DISCUSSION Moistness is necessary for chronic wounds to heal; it is needed to ensure optimal cell growth, angiogenesis, and fibrinolysis. Wounds can be treated using non-active dressings with high absorption qualities; however, these do not guarantee optimal conditions for healing, or wounds can be treated with an interactive dressing that interacts with the wound surface. The third option for treatment is the use of bioactive materials that adhere to the wound and participate directly in the individual stages of healing. CONCLUSIONS The study found that autologous growth factors had statistically significant effects on the treatment of chronic ulcers. The authors believe that this method can accelerate the healing of primary post-injury or secondary postoperative wounds of lower leg soft tissues. Key words: trophic ulcer, autologous growth factors, microangiopathy, polyneuropathy, diabetes mellitus.

Abstract
Patients with chronic leg ulcer, pressure ulcer, or diabetic foot ulcer suffer from significant disease burden. With a view to improving healthcare provision sustainably, a predictive model of time to closure (time-to-event analysis) based on claims data was developed. To identify potential predictors of wound closure, clinical information absent from statutory health insurance (SHI) data was modelled. In patients with leg ulcers, age of the patient (hazard ratios [HR] 0.99), increasing number of comorbidities (HR 0.94), inpatient stays (HR 0.74), and treatment by a specialised wound care professional (HR 1.18) were significant predictors of time to closure (adjusted model). In almost all models, the number of inpatient stays and of comorbidities predicted a lower probability of healing. In addition, the age and the sex of the patient were found to be significant predictors in some models (leg ulcer: HR 0.99; pressure ulcer: HR 0.99). Increasing number of comorbidities and inpatient stays were predictors for closure time in all models. Since these predictors may give an indication of wound severity, further clinical information should be considered in future models, as also indicated by the moderate values of the c-statistics. This requires future data linkage between SHI and primary studies (eg, registers).

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
Sickle cell disease is a disorder characterized by chronic hemolytic anemia and multiorgan disease complications. Although vaso-occlusive episodes, acute chest syndrome, and neurovascular disease frequently result in complication and have well-documented guidelines for management, the management of chronic hemolytic and vascular-related complications, such as priapism, leg ulcers, and pulmonary hypertension, is not as well recognized despite their increasing reported prevalence and association with morbidity and mortality. This chapter therefore reviews the current updates on diagnosis and management of priapism, leg ulcers, and pulmonary hypertension.

Abstract
BACKGROUND Leg ulcers are a frequent complication in patients with the inherited hemoglobin disorders. In thalassemia, the literature is limited, and factors associated with the development of leg ulcers in hemoglobin E (HbE) beta thalassemia, the most common form of severe beta-thalassemia worldwide, have not previously been reported. METHODS We reviewed all available medical records of patients with HbE beta thalassemia to document the onset of leg ulcers at the 2 largest treatment centers in Sri Lanka. We reviewed the literature to identify studies reporting outcomes of interventions for ulcers in severe thalassemia. RESULTS Of a total of 255 actively registered patients with HbE thalassemia in the 2 centers, 196 patient charts were evaluable. A leg ulcer with a documented date of onset was recorded in 45 (22%) of 196 evaluable patients, aged (mean ± SEM) 22.2 ± 1.4 years. Most had been irregularly transfused; steady-state hemoglobin was 6.4 ± 0.2 g/dL. Treatment achieving healing in 17 patients included transfusions, antibiotics, oral zinc, wound toileting, and skin grafting. CONCLUSION Leg ulcers may be more common in HbE beta thalassemia than in other forms of thalassemia. A systematic approach to treatment will be needed to document the prevalence and factors placing such patients at risk for leg ulcers. Controlled trials to evaluate the optimal treatment of this common complication are indicated.

Abstract
OBJECTIVE To critically analyze the existing randomized controlled trials (RCTs) on the clinical, economic, and psychological implications of maggot debridement therapy (MDT). DATA SOURCES An exhaustive literature search for English-language publications was conducted using MEDLINE, EMBASE, and PubMed. STUDY SELECTION Keywords used for the search were based on the PICO (Population, Intervention, Comparison, Outcome) framework. The titles, abstracts, and relevant full-text articles were screened. Seven RCTs were selected after applying the inclusion and exclusion criteria. DATA EXTRACTION Data pertaining to the primary and secondary outcomes of each study were extracted. DATA SYNTHESIS The data extracted were evaluated and categorized into clinical, economic, and psychological outcomes pertaining to MDT. A judicious evaluation of these outcomes was made, and the following conclusions were drawn. CONCLUSIONS There exists heterogeneity in the extant RCTs, but MDT appears to be effective for a quick early debridement. For diabetic foot ulcers, MDT improves debridement, controls infection, and enhances wound healing. In chronic peripheral vascular disease ulcers, it aids in early debridement, but the final outcome is equivocal. Further robust integrated health economic and parallel qualitative assessment studies are recommended to understand the cost-effectiveness and patient acceptability and experience.

Abstract
Chronic leg ulcers are a common condition among adults, causing pain and social distress. Population aging has contributed to the amplification of the disease with increased cardiovascular diseases such as myocardial infarction, stroke, limb ischemia, cancers, chronic respiratory diseases, and diabetes. The aim of this study was to evaluate the influence of the Mediterranean Diet (MD) and hydration on the healing rate of the ulcers. A group of 35 patients (M/F 16/19, mean age 78 ± 10 years) with venous, arterial, or mixed ulcers was subjected to a Food Frequency Questionnaire (FFQ) and a Hydration Habits Questionnaire (HHQ). Clinical and anthropometric data were collected. A one-year follow-up was conducted. Complete ulcer healing was observed in 26% of the patients, of whom 67% had a habit of high hydration (more than 1 liter /day), regardless of adherence to the MD. In our study population, about half showed a low adherence to the MD. A moderate-high adherence to the MD showed an increase of arterial ulcer healing compared to subjects with a low adherence to the MD, however, only when associated to a consumption of more than 1 liter of water daily. In conclusion, dietary assessments could help identify patients who are likely to benefit from nutritional interventions for improving overall health and wound healing. The habit of high hydration, namely more than 1 liter daily, can influence the wound healing rate.
