Abstract
OBJECTIVE The aim of the study was to determine what factors determine the quality of rehabilitation clinical practice guidelines. DESIGN Six databases were searched for articles that had applied the Appraisal of Guidelines for Research & Evaluation II quality assessment tool to rehabilitation clinical practice guidelines. The 573 deduplicated abstracts were independently screened by two authors, resulting in 81 articles, the full texts of which were independently screened by two authors for Appraisal of Guidelines for Research & Evaluation II application to rehabilitation clinical practice guidelines, resulting in a final selection of 40 reviews appraising 504 clinical practice guidelines. Data were extracted from these by one author and checked by a second. Data on each clinical practice guideline included the six Appraisal of Guidelines for Research & Evaluation II domain scores, as well as the two Appraisal of Guidelines for Research & Evaluation II global evaluations. RESULTS All six Appraisal of Guidelines for Research & Evaluation II domain scores were statistically significant predictors of overall clinical practice guideline quality rating; D3 (rigor of development) was the strongest and D1 (scope and purpose) the weakest (overall model P < 0.001, R2 = 0.53). Five of the six domain scores were significant predictors of the clinical practice guideline use recommendation, with D3 the strongest predictor and D5 (applicability) the weakest (overall model P < 0.001, pseudo R2 = 0.53). CONCLUSIONS Quality of rehabilitation clinical practice guidelines may be improved by addressing key domains such as rigor of development.

Abstract
Purpose Delay in reporting foot symptoms in patients with diabetes to health-care professionals is said to be responsible for limb amputation. While reasons for these delays have been investigated elsewhere, they are not well documented in Nigeria. This study explored the causes of delayed presentation in a Nigerian sample of patients with diabetic foot ulcers. Method The study followed an explorative qualitative design in which the lived experience of eight participants with diabetes were explored. The participants completed in-depth interviews which were digitally audio-recorded and transcribed verbatim. Data were analysed thematically using deductive reasoning. Results The study identified four themes which included knowledge and awareness of foot challenges, risk perception, health seeking triggers and behaviours and competing priority as the factors responsible for delay in presentation of diabetic foot complications. Conclusions Limited knowledge and awareness and negative health seeking behaviours including self-management and consultation of traditionalists were the major reasons for delays.

Abstract
PURPOSE Diabetic foot disease is one of the most serious and expensive complications of diabetes. Patient-reported outcome measures (PROMs) analyse patients' perception of their disability, functionality and health. The goal of this work was to conduct a systematic review regarding the specific PROMs related to the evaluation of diabetic foot disease and to extract and analyse the values of their measurement properties. METHODS Electronic databases included were PubMed, CINAHL, Scopus, PEDro, Cochrane, SciELO and EMBASE. The search terms used were foot, diabet*, diabetic foot, questionnaire, patient-reported outcome, self-care, valid*, reliabil*. Studies whose did not satisfy the Critical Appraisals Skills Programme (CASP) Diagnostic Study Checklist were excluded. The measurement properties extracted were: Internal Consistency, Test-retest, Inter-rater and Intra-rater, Standard Error of Measurement, Minimum Detectable Measurement Difference, Content Validity, Construct Validity, Criterion Validity and Responsiveness. RESULTS The PROMs selected for this review were 12 questionnaires. The Diabetic foot self-care questionnaire (DFSQ-UMA) and the Questionnaire for Diabetes Related Foot Disease (Q-DFD) were the PROMs that showed the highest number of completed measurement properties. CONCLUSION According to the results, it is relevant to create specific questionnaires for the evaluation of diabetic foot disease. It seems appropriate to use both DFSQ-UMA and Q-DFD when assessing patients with diabetic foot disease.

Abstract
Vascular assessment is a critical component of wound care. Current routine noninvasive vascular studies have limitations which can give a false sense of security of the presence of adequate perfusion for healing. Near-infrared imaging modalities can serve as an additional diagnostic assessment of wounds in which adequate perfusion is a concern. Correct interpretation of near-infrared images obtained is critical as subtleties that exist in the acute and chronic wound population goes beyond the interpretation that increased signal is consistent with adequate perfusion for healing. The objective of this paper is to educate providers on the correct interpretation of this point-of-care imaging modality in day-to-day wound-care practice to guide clinical decision-making for rapid wound resolution.

Abstract
Mesenchymal stem cell (MSC) dysfunction is a serious complication in ageing and age-related inflammatory diseases such as type 2 diabetes mellitus. Inflammation and oxidative stress-induced cellular senescence alter the immunomodulatory ability of MSCs and hamper their pro-regenerative function, which in turn leads to an increase in disease severity, maladaptive tissue damage and the development of comorbidities. Targeting stem/progenitor cells to restore their function and/or protect them against impairment could thus improve healing outcomes and significantly enhance the quality of life for diabetic patients. This review discusses the dysregulation of MSCs' immunomodulatory capacity in the context of diabetes mellitus and focuses on intervention strategies aimed at MSC rejuvenation. Research pertaining to the potential therapeutic use of either pharmacological agents (NFкB antagonists), natural products (phytomedicine) or biological agents (exosomes, probiotics) to improve MSC function is discussed and an overview of the most pertinent methodological considerations given. Based on in vitro studies, numerous anti-inflammatory agents, antioxidants and biological agents show tremendous potential to revitalise MSCs. An integrated systems approach and a thorough understanding of complete disease pathology are however required to identify feasible candidates for in vivo targeting of MSCs.

Abstract
Diabetic foot is among the most common complications of patients with diabetes. One of the known causes of foot ulceration is ankle equinus, which increases the pressure on the plantar surface during ambulation. Conversely, equinus contracture can be caused by a complicated wound, and it may be due to prolonged immobilization. In this paper, we reviewed the pathogenesis of both conditions and their clinical considerations. Poor glycemic control in patients with diabetes may result in angiopathy and neuropathy as an underlying condition. An ulcer can be precipitated by an injury, improper foot care, or increased biomechanical loading as seen in elevated plantar pressure following equinus contracture. Equinus contracture may be a direct effect of hyperglycemia or can arise in combination with another pathway, for example, involving the activation of transforming growth factor β. Static positioning resulting from any prior foot wound may develop fibrotic changes leading to contracture. Wound healing promoting factors can also result in overhealing outcomes such as hypertrophic scarring and fibrosis. The body’s repair mechanism during the healing cascade activates repair cells and myofibroblasts, which also serve as the main producers and organizers of the extracellular matrix. Considering this intricate pathogenesis, appropriate interventions are essential for breaking the vicious cycle that may disturb wound healing.

Abstract
Diabetic foot ulcers (DFUs) are a common but highly morbid complication of long-standing diabetes, carrying high rates of associated major amputation and mortality. As the global incidence of diabetes has increased, along with the lifespan of the diabetic patient, the worldwide burden of DFUs has grown steadily. Outcomes in diabetes and DFUs are known to depend strongly on social determinants of health, with worse outcomes noted in minority and socioeconomically disadvantaged populations. Effective treatment of DFUs is complex, requiring considerable expenditure of resources and significant cost to the health care system. Comprehensive care models with multidisciplinary teams have proven effective in the treatment of DFUs by decreasing barriers to care and increasing access to the multiple specialists required to provide timely and effective DFU procedural intervention, surveillance, and preventative care. Vascular surgeons are an integral part throughout the cycle of care for DFUs and should be involved early in the course of such patients to maximize their contributions to a multidisciplinary care model.

Application and Clinical Effectiveness of Antibiotic-Loaded Bone Cement to Promote Soft Tissue Granulation in the Treatment of Neuropathic Diabetic Foot Ulcers Complicated by Osteomyelitis: A Randomized Controlled Trial. J Diabetes Res 2021; 2021:9911072. [PMID: 34337074 PMCID: PMC8294998 DOI: 10.1155/2021/9911072] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 03/12/2021] [Accepted: 06/25/2021] [Indexed: 11/17/2022] Open
Abstract
This study explored the clinical effectiveness of antibiotic-loaded bone cement on primary treatment of diabetic foot infection. This is a randomized controlled study, including thirty-six patients with diabetic foot ulcer complicated by osteomyelitis who had undergone treatment between May 2018 and December 2019. Patients were randomly divided into control group (group A) and study group (group B). Patients in the intervention group received antibiotic-loaded bone cement repair as primary treatment, while patients in the control group received conventional vacuum sealing draining treatment. Clinical endpoints were assessed and compared between the two groups, including wound healing time, wound bacterial conversion, NRS pain score, number of wound dressing changes, and average hospitalization time. All patients were followed up for a period of 12 months after discharge. Results show that compared with the control group, patients in the study group had significant difference in the number of patients for baseline pathogens eradication, short NRS pain score, hospital length of stay and cost, wound surface reduction, healing time, low rate of complications, and infection recurrence. Based on the findings, we conclude that antibiotic-loaded bone cement can be used for treatment of wound in patient with diabetic foot infection. It can help to control wound infections, shorten hospital length of stay, reduce medical cost, and relieve both doctors' and patients' burden. The application of antibiotic-loaded bone cement is suitable for diabetic wound with soft tissue infection or osteomyelitis.

Abstract
AIMS To estimate the rate at which people with diabetes and a low risk of foot ulceration change diabetic foot ulceration risk status over time, and to estimate the rate of ulceration, amputation and death among this population. METHODS We conducted an observational study of 10 421 people with diabetes attending foot screening in an outpatient setting in NHS Fife, UK, using routinely collected data from a national diabetes register, NHS SCI Diabetes. We estimated the proportion of people who changed risk status and the cumulative incidence of ulceration, amputation and death, respectively, among people with diabetes at low risk of diabetic foot ulceration at 2-year follow-up. RESULTS At 2-year follow-up, 5.1% (95% CI 4.7, 5.6) of people with diabetes classified as low risk at their first visit had progressed to moderate risk. The cumulative incidence of ulceration, amputation and death was 0.4% (95% CI 0.3, 0.6), 0.1% (95% CI 0.1, 0.2) and 3.4% (95% CI 3.1, 3.8), respectively. CONCLUSIONS At 2-year follow-up, 5% of people at low risk of diabetic foot ulceration changed clinical risk status and <1% of people experienced foot ulceration or amputation. These findings provide information which will help to inform the current debate regarding optimal foot screening intervals.

Abstract
INTRODUCTION Diabetic foot represents one of the most serious and expensive complications of diabetes and is subject to a high percentage of amputations that are almost always preceded by ulcers ascribable to neuropathy and/or vasculopathy. Videocapillaroscopy (VCS) can be a valuable aid in order to uncover morpho-structural anomalies in the vascular bed, both at the level of the oral mucosa and at the level of the terminal vessels of the lower limb. MATERIALS AND METHODS Sixty subjects divided into 4 groups were enrolled: 15 healthy subjects; 15 patients with diabetes for more than 10 years without ulcerative foot lesions; 15 patients with neuropathic diabetic foot (clinical diagnosis, MDNS); 15 patients with ischemic diabetic foot (clinical diagnosis, ABI, lower limb doppler). A complete videocapillaroscopic mapping of the oral mucosa was carried out on each patient. The areas investigated were: labial mucosa, the retro-commissural region of the buccal mucosa, and the vestibular masticatory mucosa (II and V sextant). RESULTS The analysis of the morphological and densitometric characteristics of the capillaries revealed the following: a significant reduction in capillary density in neuropathic (mean ± SD 7.32 ± 2.1) and ischemic patients (mean ± SD 4.32 ± 3.2) compared to the control group of patients (both diabetic mean ± SD 12.98 ± 3.1 and healthy mean ± SD 19.04 ± 3.16) (ANOVA test and Bonferroni t test p < 0.05); a reduction in the average length of the capillaries and a significant increase in tortuosity (ANOVA test and Bonferroni t test p < 0.05). In the neuropathic patients, a recurrent capillaroscopic pattern that we defined as "sun" was found, with capillaries arranged radially around an avascular area. CONCLUSIONS The data obtained from this preliminary study suggest a potential diagnostic role of oral capillaroscopy in the early and subclinical identification of microangiopathic damage in patients with diabetic foot.

Abstract
OBJECTIVE To compare the effectiveness of a temporary topical external haemostat (OMNI-STAT Granules, Omni-stat Medical Inc., US) versus the use of electrocautery for bleeding control in patients who have undergone surgical wound debridement. Time saved in the operating room (OR) was evaluated. METHOD A prospective evaluation of use of a topical haemostat in an OR setting was compared with retrospective data collected using electrocautery to understand the time-saving benefits of using a topical haemostat versus electrocautery. RESULTS A total of 52 patients were treated with the topical haemostat, and 89 patients with electrocautery. The topical haemostat was shown to be as effective in achieving haemostasis post-surgical debridement as electrocautery, with the added benefits of significant time savings in the OR (reducing the mean total OR time by 19.1%). Additionally, preprocedure and surgical procedure times in patients treated with the topical haemostat were significantly reduced. The results showed that wounds treated with the topical haemostat demonstrated a more advanced stage of healing, which may be a result of the lack of tissue damage demonstrated with the topical haemostat compared with electrocautery. CONCLUSION This study found that the temporary topical haemostat was equally as effective as cauterisation in achieving haemostasis. In addition, significant saving in OR time was demonstrated relative to electrocautery. The improved OR times may translate into increased cost-effectiveness, relative to electrocautery, by increasing the number of surgical cases per day and/or using resources more effectively to treat more patients. It may also enable bleeding control in the outpatient clinic or at the bedside, freeing up costly OR time and enabling more effective management of healthcare resources.

Abstract
The most important and consulted guidelines dealing with not healing foot ulcers suggest the measurement of the foot perfusion (FP) to exclude the critical limb ischemia (CLI), because of the high risk of limb amputation. But the recommended cut-off values of FP fail to include all the heterogeneity of patients of the real-life with a not healing ulcer. Often these patients are diabetics with a moderate PAD but with a high level of infection. To meet this goal, in 2014, the Society for Vascular Surgery has published the "Lower Extremity Threatened Limb Classification System: Risk stratification based on Wound, Infection, and foot Ischemia (WIfI)." This new classification system has changed the criteria of assessment of limb amputation risk, replacing the single cut-off value role with a combination of a spectrum of perfusion values along with graded infection and dimension levels of skin ulcers. The impact of this new classification system was remarkable so to propose the substitution of the CLI definition, with the new Critical limb-threatening ischemia (CLTI), that seems to define the limb amputation risk more realistically.

Abstract
Over half of people with diabetes mellitus develop diabetic polyneuropathy (DPN), which is a major cause of reduced quality of life due to disabling neuropathic pain, sensory loss, gait instability, fall-related injury, and foot ulceration and amputation. The latter represents a major health and economic burden, with lower limb amputation rates related to diabetes increasing in the UK. There is a need for early diagnosis of DPN so that early management strategies may be instigated, such as achieving tight glucose control and management of cardiovascular risk factors, in an attempt to slow its progression. To this end, a one-stop microvascular assessment involving a combined eye, foot and renal screening clinic has proven feasible in the UK. Unfortunately, there are currently no approved disease-modifying therapies for DPN. Some disease-modifying agents have demonstrated efficacy, but further large trials using appropriate clinical endpoints are required before these treatments can be routinely recommended. There has been emerging evidence highlighting a reduction in vitamin D levels in cases of painful DPN and the potential for vitamin D supplementation in deficient individuals to improve neuropathic pain; however, this needs to be proved in randomised clinical trials. The use of established agents for neuropathic pain in DPN is limited by poor efficacy and adverse effects, but patient stratification using methods such as pain phenotyping are being tested to determine whether this improves the outcomes of such agents in clinical studies. In addition, innovative approaches such as the topical 8% capsaicin patch, new methods of electrical stimulation and novel therapeutic targets such as NaV1.7 offer promise for the future. This article aims to discuss the challenges of diagnosing and managing DPN and to review current and emerging lifestyle interventions and therapeutic options.
