Saghdaoui LB, Lampridou S, Racaru S, Davies AH, Wells Met al., 2023, Healthcare interventions to aid patient self-management of lower limb wounds: A systematic scoping review, International Wound Journal, Vol: 20, Pages: 1304-1315, ISSN: 1742-4801

Chronic lower limb wounds can be described as having the inability to progress through stages of wound healing. Although 80% of lower limb wounds develop as a result of venous insufficiency, other causes include arterial disease and diabetes. In addition to the sustained impact on quality of life, the chronicity of lower limb wounds presents a significant financial burden to healthcare systems. Self-management is a fundamental aspect of the long-term management of chronic illness and its relevance has intensified since the start of the global pandemic. The objective of this systematic scoping review was to define what the self-management of a lower limb wound entails and explore the interventions available to support patients to self-manage. A total of seven articles were evaluated. There was limited consensus regarding the definition and components of self-management in this area. Interventions involved patients participating in additional exercise, wound care, and lifestyle behaviours such as limb elevation and skin care. Only two studies applied theory and only one evaluated participant acceptability of interventions, making it difficult to assess the feasibility of implementation. Although the evidence reviewed provides some insight into the self-management of a lower limb wound, theoretically-guided research is needed in this area.

Elghazaly H, Howard T, Sharan S, Mohamed O, Sounderajah V, Mehar Z, Davies A, Jaffer U, Normahani Pet al., 2023, Evaluating the prognostic performance of bedside tests used for peripheral arterial disease diagnosis in the prediction of diabetic foot ulcer healing, BMJ Open Diabetes Research and Care, Vol: 11, Pages: 1-11, ISSN: 2052-4897

Introduction:Diabetic foot ulceration (DFU) is a common and challenging complication of diabetes. Risk stratification can guide further management. We aim to evaluate the prognostic performance of bedside tests used for peripheral arterial disease (PAD) diagnosis to predict DFU healing.Research Design and Methods:TrEAD was a prospective observational study comparing the diagnostic performance of commonly-used tests for PAD diagnosis. We performed a secondary analysis assessing whether these could predict DFU healing. Follow-up was performed prospectively for 12-months. The primary outcome was sensitivity for predicting ulcer healing. Secondary endpoints were specificity, predictive values, and likelihood ratios for ulcer healing.Results:123 of TrEAD participants with DFU were included. In 12-months, 52.8% of ulcers healed. The best negative diagnostic likelihood ratio was observed for the PAD-scan (mono or biphasic with adverse features) (NDLR 0.35, 95% CI 0.14-0.90). The highest positive likelihood ratios were observed for TBPI of 0.2 (PDLR 7.67, 95% CI 0.91-64.84) and TcPO2 of 20mmHg (PDLR 2.68, 95% CI 0.54-13.25). Cox proportional hazard modelling demonstrated significantly greater probabilities of healing with triphasic waveforms (HR = 2.54, 95% CI 1.23 – 5.3, p=0.012) and biphasic waveforms with non-adverse features (HR = 13.67, 95% CI 4.78 – 39.1, p<0.001) on PAD-scan. Conclusions:No single test performed well enough to be used in isolation as a prognostic marker for the prediction of DFU healing.

Objectives To investigate the acceptability and safety of neuromuscular stimulation (NMES) as an adjunct for rehabilitation after vascular and general surgery.Methods and analysis Prospective, single-centre, single-blind, parallel group, randomised controlled study. This study will be conducted in a single-centre, secondary care setting (National Healthcare Service Hospital) in the UK. All patients aged over 18 years undergoing vascular or general surgery with Rockwood Frailty Score of 3 or above on admission. Exclusion is inability or unwillingness to participate in trial, implanted electrical device, pregnancy and acute deep vein thrombosis. Target number of recruitment is 100. Participants will be randomly assigned to active NMES group (group A) or placebo NMES group (group B) prior to surgery. Participants will be blinded and asked to use the NMES device, 1–6 sessions daily (30 min per session) after surgery in addition to standard National Health Service rehabilitation care until discharge. The primary study outcomes are acceptability and safety of NMES assessed by the device satisfaction questionnaire on discharge and adverse events recorded during hospital stay. The secondary outcomes are the postoperative recovery and cost-effectiveness compared between two groups, assessed by various activity tests, mobility and independence measures and questionnaires.Ethics and dissemination Ethical approvals were provided by London-Harrow Research Ethics Committee (REC) and the Health Research Authority (HRA), Ref: 21/PR/0250. Findings will be published in a peer-reviewed journal and presented at national and international conferences.Trial registration number NCT04784962.

Objective: The aim of this study was to identify potential biomarkers predictive of healing or failure to heal in a population with venous leg ulceration.Summary Background Data: Venous leg ulceration presents important physical, psychological, social and financial burdens. Compression therapy is the main treatment, but it can be painful and time-consuming, with significant recurrence rates. The identification of a reliable biochemical signature with the ability to identify nonhealing ulcers has important translational applications for disease prognostication, personalized health care and the development of novel therapies.Methods: Twenty-eight patients were assessed at baseline and at 20 weeks. Untargeted metabolic profiling was performed on urine, serum, and ulcer fluid, using mass spectrometry and nuclear magnetic resonance spectroscopy.Results: A differential metabolic phenotype was identified in healing (n = 15) compared to nonhealing (n = 13) venous leg ulcer patients. Analysis of the assigned metabolites found ceramide and carnitine metabolism to be relevant pathways. In this pilot study, only serum biofluids could differentiate between healing and nonhealing patients. The ratio of carnitine to ceramide was able to differentiate between healing phenotypes with 100% sensitivity, 79% specificity, and 91% accuracy.Conclusions: This study reports a metabolic signature predictive of healing in venous leg ulceration and presents potential translational applications for disease prognostication and development of targeted therapies.

Introduction Hospital-acquired thrombosis (HAT) is defined as any venous thromboembolism (VTE)-related event during a hospital admission or occurring up to 90 days post discharge, and is associated with significant morbidity, mortality and healthcare-associated costs. Although surgery is an established risk factor for VTE, operations with a short hospital stay (<48 hours) and that permit early ambulation are associated with a low risk of VTE. Many patients undergoing short-stay surgical procedures and who are at low risk of VTE are treated with graduated compression stockings (GCS). However, evidence for the use of GCS in VTE prevention for this cohort is poor.Methods and analysis A multicentre, cluster randomised controlled trial which aims to determine whether GCS are superior in comparison to no GCS in the prevention of VTE for surgical patients undergoing short-stay procedures assessed to be at low risk of VTE. A total of 50 sites (21 472 participants) will be randomised to either intervention (GCS) or control (no GCS). Adult participants (18–59 years) who undergo short-stay surgical procedures and are assessed as low risk of VTE will be included in the study. Participants will provide consent to be contacted for follow-up at 7-days and 90-days postsurgical procedure. The primary outcome is the rate of symptomatic VTE, that is, deep vein thrombosis or pulmonary embolism during admission or within 90 days. Secondary outcomes include healthcare costs and changes in quality of life. The main analysis will be according to the intention-to-treat principle and will compare the rates of VTE at 90 days, measured at an individual level, using hierarchical (multilevel) logistic regression.Ethics and dissemination Ethical approval was granted by the Camden and Kings Cross Research Ethics Committee (22/LO/0390). Findings will be published in a peer-reviewed journal and presented at national and international conferences.Trial registration number ISRCT

Turner B, Jasionowska S, Machin M, Javed A, Gwozdz A, Shalhoub J, Onida S, Davies Aet al., 2023, Systematic review and meta-analysis of exercise therapy for venous leg ulcer healing and recurrence, Journal of vascular surgery. Venous and lymphatic disorders, Vol: 11, Pages: 219-226, ISSN: 2213-3348

Objective:National guidelines in the United Kingdom have recommended regular exercise for individuals with venous leg ulceration. However, data on the effects of exercise on ulcer healing and recurrence are sparse. In the present study, we aimed to quantify the evidence for exercise regarding venous ulcer healing with respect to the primary outcomes of the proportion of healed ulcers and rate of ulcer recurrence. The secondary outcomes were improvement in ulcer symptoms, ulcer healing time, quality of life, compliance, and adverse events reported.Methods:The review followed PRISMA (preferred reporting items for systematic reviews and meta-analyses) guidelines using a registered protocol (CRD42021220925). The MEDLINE and Embase databases and Cochrane Central Register of Controlled Trials, ClinicalTrials.gov, European Union Clinical Trials, and International Standard Randomised Controlled Trial Number registries were searched up to April 6, 2022 and included studies comparing exercise therapy and compression vs compression alone. Data for the proportion of healed ulcers were pooled using a fixed effects meta-analysis.Results:After screening 1046 reports, 7 were included, with 121 participants allocated to exercise therapy and 125 to compression alone. All the reports were of randomized controlled trials and had reported ulcer healing at 12 weeks, with a pooled relative risk of ulcer healing of 1.38 for exercise vs compression (95% confidence interval, 1.11-1.71). Only one study had reported on recurrence; thus, data pooling was not performed. No differences between exercise and usual care were demonstrated. Compliance with exercise ranged from 33% to 81%. The included studies demonstrated low enrollment and a high risk of bias. Also, most of the trials had failed to demonstrate any differences in activity completed between the intervention and control arms.Conclusions:A paucity of studies has examined leg ulcer recurrence after exercise programs, with no evidence to s

ObjectivesExercise improves haemodynamic parameters in patients with chronic venous disease. There is a paucity of evidence on its effect in post-thrombotic syndrome (PTS). The aim of this systematic review is to assess the impact of exercise in PTS.MethodsAdhering to PRISMA guidelines and following PROSPERO registration (CRD42021220924), MEDLINE, Cochrane Library, EMBASE database, and trial registries were searched on 19th May 2022.ResultsOne article met the inclusion criteria and a narrative synthesis was carried out. The included randomised controlled trial reported a between-group mean difference of 4.6 points (p = .027) in the VEINES-QOL score and −2.0 points (p = .14) in the Villalta score, in favour of exercise therapy. The statistical significance threshold was not reached.ConclusionData on exercise in PTS remains sparse but exercise appears to be a safe intervention. In the context of this literature, a potential future trial and outcome reporting measures are suggested.

Introduction:Peripheral arterial disease (PAD) is a key risk factor for cardiovascular disease, foot ulceration and lower limb amputation in people with diabetes. Early diagnosis of PAD can enable optimisation of therapies to manage these risks. Its diagnosis is fundamental though challenging in the context of diabetes. Although a variety of diagnostic bedside tests are available, there is no agreement as to which is the most accurate in routine clinical practice. The aim of this study is to determine the diagnostic performance of a variety of tests (audible waveform assessment, visual waveform assessment, ankle brachial pressure index (ABPI), exercise ABPI and toe brachial pressure index (TBPI)) for the diagnosis of PAD in people with diabetes as determined by a reference test (computed tomography angiography (CTA) or magnetic resonance angiography (MRA)). In selected centres, we also aim to evaluate the performance of a new point-of-care duplex ultrasound scan (PAD-scan).Methods and analysis:A prospective multicentre diagnostic accuracy study (ClinicalTrials.gov Identifier NCT05009602). We aim to recruit 730 people with diabetes from 18 centres across the United Kingdom (UK), covering primary and secondary healthcare. Consenting participants will undergo the tests under investigation. Reference tests (CTA or MRA) will be performed within six weeks of the index tests. Imaging will be reported by blinded consultant radiologists at a core imaging lab, using a validated scoring system, which will also be used to categorise PAD severity. The presence of one or more arterial lesions of 50% stenosis, or tandem lesions with a combined value of 50%, will be used as the threshold for the diagnosis of PAD. The primary outcome measure of diagnostic performance will be test sensitivity.Ethics and Dissemination: The study has received approval from the National Research Ethics Service (NRES) (REC reference 21/PR/1221). Results will be disseminated through research presentatio

International evidence-based guidelines recommend preoperative duplex ultrasound mapping in the assessment of chronic venous disease, and concurrent ultrasound imaging to guide superficial endovenous interventions such as endovenous laser ablation, radiofrequency ablation, cyanoacrylate adhesive closure, and sclerotherapy (ultrasound-guided sclerotherapy). Other imaging modalities such as venography, alone or in combination with computed tomography scan or magnetic resonance imaging, may be included in the preoperative assessment of a small and select group of patients to exclude central venous obstruction, certain deep venous pathologies, pelvic origin extrapelvic varices, and complex vascular malformations. The signatory scientific and medical societies recommend against the routine use of fluoroscopy and other radiation-based imaging in the investigation and treatment of superficial venous disease.

Gueroult A, Al-Balah A, Shalhoub J, Davies Aet al., 2022, Nickel hypersensitivity and endovascular devices: a systematic review and meta-analysis, Heart, Vol: 108, Pages: 1707-1715, ISSN: 1355-6037

Objective Nickel allergy is common; endovascular specialists are often confronted with nickel allergic patients ahead of the implantation of endovascular devices, many of which are nickel-containing. Our aim was to elucidate whether nickel hypersensitivity is significantly associated with worse or adverse outcomes after placement of a nickel-containing endovascular device.Methods Inclusion criteria were: endovascular and transcatheter procedures for coronary, structural heart, neurovascular and peripheral vascular pathology involving nickel-allergic patients. All adverse outcomes were included as defined by included studies. A systematic review and meta-analysis were undertaken using a random-effects model. Searches of MEDLINE and EMBASE were conducted for articles published 1947–2019.Results 190 records were identified, 78 articles were included for qualitative synthesis and 15 met criteria for meta-analysis. Patch-test confirmed nickel allergy was associated with an increased risk of adverse outcomes following implantation of a nickel-containing endovascular device (n=14 articles, 1740 patients; OR 2.61, 95% CI 1.41 to 4.85). This finding further was observed in coronary (n=12 articles, 1624 patients; OR 1.94, 95% CI 1.16 to 3.23) and structural heart subgroups (n=2 articles, 83 patients; OR 52.28, 95% CI 1.31 to 2079.14), but not in the neurovascular subgroup (n=1 article, 33 patients; OR 3.04, 95% CI 0.59 to 15.72) or with a patient-reported history of nickel allergy (n=2 articles, 207 patients; OR 2.14, 95% CI 0.23 to 19.70).Conclusions Patch-tested nickel allergy is associated with an increased risk of adverse outcomes following endovascular device implantation and alternative treatment options should be considered. Specialists faced with patients’ self-reporting nickel allergy should consider proceeding to diagnostic patch-testing.

Objective: The primary objective of this systematic review and meta-analysis was to elucidate the rate of venous thromboembolism (VTE) following endovenous varicose vein intervention with mechanical thromboprophylaxis and additional pharmacological thromboprophylaxis, versus mechanical thromboprophylaxis alone.Summary Background Data: The VTE rate following endovenous procedures is higher than other day-case procedures and could be reduced with pharmacological thromboprophylaxis.Methods: The review followed PRISMA guidelines with a registered protocol (PROSPERO: CRD42021274963). Studies of endovenous intervention for superficial venous incompetence reporting the predefined outcomes with at least 30 patients were eligible. Data were pooled with a fixed effects model.Results: There were 221 trials included in the review (47 randomised trial arms, 105 prospective cohort studies and 69 retrospective studies). In randomised trial arms, the rate of deep venous thrombosis with additional pharmacological thromboprophylaxis was 0.52% (95% CI 0.23-1.19%) (9 studies; 1095 patients; 2 events), versus 2.26% (95% CI 1.81-2.82%) (38 studies; 6951 patients; 69 events) with mechanical thromboprophylaxis alone. The rate of pulmonary embolism in randomised trial arms with additional pharmacological thromboprophylaxis was 0.45% (95% CI 0.09-2.35) (5 studies, 460 participants, 1 event) versus 0.23% (95% CI 0.1-0.52%) (28 studies, 4834 participants, 3 events) for mechanical measures alone. The rate of EHIT grade III-IV was 0.35% (95% CI 0.09-1.40) versus 0.88% (95% CI 0.28-2.70%). There was one VTE-related mortality and one instance of major bleeding, with low rates of minor bleeding.Conclusions: There is a significant reduction in the rate of DVT with additional pharmacological thromboprophylaxis and routine prescription of anticoagulation following endovenous varicose vein intervention should be considered. VTE risk for individual study participants is heterogeneous and risk stratifica

Smith S, Normahani P, Lane T, Hohenschurz-Schmidt D, Oliver N, Davies AHet al., 2022, Prevention and management strategies for diabetic neuropathy, Life, Vol: 12, Pages: 1185-1185, ISSN: 2075-1729

Diabetic neuropathy (DN) is a common complication of diabetes that is becoming an increasing concern as the prevalence of diabetes rapidly rises. There are several types of DN, but the most prevalent and studied type is distal symmetrical polyneuropathy, which is the focus of this review and is simply referred to as DN. It can lead to a wide range of sensorimotor and psychosocial symptoms and is a major risk factor for diabetic foot ulceration and Charcot neuropathic osteoarthropathy, which are associated with high rates of lower limb amputation and mortality. The prevention and management of DN are thus critical, and clinical guidelines recommend several strategies for these based on the best available evidence. This article aims to provide a narrative review of DN prevention and management strategies by discussing these guidelines and the evidence that supports them. First, the epidemiology and diverse clinical manifestations of DN are summarized. Then, prevention strategies such as glycemic control, lifestyle modifications and footcare are discussed, as well as the importance of early diagnosis. Finally, neuropathic pain management strategies and promising novel therapies under investigation such as neuromodulation devices and nutraceuticals are reviewed.
