Radio-iodination and biological evaluation of pentoxifylline as a novel probe for diagnosis of intermittent claudication. Appl Radiat Isot 2022; 189:110429. [PMID: 36037727 DOI: 10.1016/j.apradiso.2022.110429] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/27/2021] [Revised: 06/30/2022] [Accepted: 08/16/2022] [Indexed: 11/20/2022]
Abstract
The diagnosis of intermittent claudication (IC) is challenging. Imaging with radiopharmaceuticals provides a new method for detecting acute IC. Pentoxifylline improves blood flow to ischemic tissues via increasing erythrocyte elasticity and inhibiting platelet aggregation. Pentoxifylline was radio-iodinated with radioiodine-131 (131I) through a direct electrophilic substitution reaction. Furthermore, various factors that might influence the radiolabeling strategy were investigated. The radiochemical yield of [131I]iodopentoxiphyline was evaluated by using paper chromatography and HPLC methods. The biodistribution pattern of [131I]iodopentoxiphyline was studied, where Swiss albino mice was used as a model of acute limb ischemia-reperfusion. The maximum radiochemical yield of pentoxifylline was found to be 94.11 ± 2.35%. The biodistribution findings revealed that [131I]iodopentoxiphyline was significantly deposited at the ischemic site (left hind limbs), with encouraging target/non-target (T/NT) ratios. At 0.25 and 1 h post injection, the uptake of [131I]iodo-pentoxifylline was 5.30 ± 0.30 and 9.98 ± 1.12%, respectively. Also, the maximum T/NT ratio for [131I]iodo-pentoxifylline (9.45 ± 0.26) was obtained at 0.25 h post injection. Due to safety and selectivity, [131I]iodo-pentoxifylline may be a good prospective diagnostic tool for early identification of IC. Moreover, the outcome of this study can be expected to apply to I-123 as well.

Abstract
The objective of this study was to evaluate a measure of the responsiveness and reliability of the pulse volume recording upstroke ratio (PVRr). A database of 389 subjects undergoing lower extremity revascularization was analyzed. Subjects were included in the analysis if they had undergone pedal radiographs, had PVRs performed pre- and postlower extremity revascularization, and had regular pulsatile digital waveforms with a pressure recording on both PVRs. The responsiveness of the PVRr was assessed by means of the postoperative percent change in comparison to the digital pressures. A statistically significant negative correlation was observed (Pearson -0.421; p = .007) indicating that as digital pressures increased, the PVRr decreased. Further, measurement of the reliability of the PVRr was performed on a selection of 10 recordings by 2 residents and 3 board-certified surgeons. The observed intraclass correlation coefficient of measurements was 0.960. Results of this investigation provide evidence in support of the responsiveness and inter-rater reliability in the calculation of the pulse volume recording upstroke ratio.

Abstract
The presence of medial arterial calcific sclerosis is known to cause inaccuracy in the interpretation of noninvasive vascular testing. This substantially limits the utility of an important baseline diagnostic test for peripheral arterial disease. Therefore, the objective of this investigation was to derive a method to effectively factor out calcification in the interpretation of the ankle and digital brachial indices. The noninvasive vascular testing results of 160 subjects were stratified into the absence of calcification, mild calcification, moderate calcification, and severe calcification based on plain film radiographic findings of the infrageniculate vessels. Measurements were then performed of the pulse volume recording (PVR) waveforms at brachial, ankle and digital anatomic levels to include PVR wavelength and PVR upstroke length, with a calculation of the ratio of PVR upstroke length to PVR wavelength. These measurements were compared between groups and then correlated to the ankle and digital brachial indices. A significant difference was observed in the PVR upstroke ratio between the 3 anatomic levels (0.1818 vs 0.2622 vs 0.3191; p < .001), but not between the 4 calcification groups (0.2457 vs 0.2363 vs 0.2694 vs 0.2631; p = .242). A significant negative correlation was observed between the PVR upstroke ratio and the ankle brachial index (ABI) (Pearson -0.454; p = .002) with linear regression indicating the relationship is defined by the formula: Effective ankle brachial index = 1.17 - (1.33 × PVR upstroke ratio at ankle level). A significant negative correlation was also observed between the PVR upstroke ratio and the digital brachial index (Pearson -0.553; p < .001) with linear regression indicating the relationship is defined by the formula: Effective toe brachial index = 1.04 - (1.61 × PVR upstroke ratio at digital level). The results of this investigation demonstrate the feasibility of, and provide equations to approximate, the effective ankle brachial and toe brachial indices in the setting of medial arterial calcification.

Abstract
OBJECTIVE To develop and validate a nomogram for predicting the risk of peripheral artery disease (PAD) in patients with type 2 diabetes mellitus (T2DM) and assess its clinical application value. METHODS Clinical data were retrospectively collected from 474 patients with T2DM at the Air Force Medical Center between January 2019 and April 2022. The patients were divided into training and validation sets using the random number table method in a ratio of 7:3. Multivariate logistic regression analysis was performed to identify the independent risk factors for PAD in patients with T2DM. A nomogram prediction model was developed based on the independent risk factors. The predictive efficacy of the prediction model was evaluated using the consistency index (C-index), area under the curve (AUC), receiver operating characteristic (ROC) curve, Hosmer-Lemeshow (HL) test, and calibration curve analysis. Additionally, decision curve analysis (DCA) was performed to evaluate the prediction model's performance during clinical application. RESULTS Age, disease duration, blood urea nitrogen (BUN), and hemoglobin (P<0.05) were observed as independent risk factors for PAD in patients with T2DM. The C-index and the AUC were 0.765 (95% CI: 0.711-0.819) and 0.716 (95% CI: 0.619-0.813) for the training and validation sets, respectively, indicating that the model had good discriminatory power. The calibration curves showed good agreement between the predicted and actual probabilities for both the training and validation sets. In addition, the P-values of the HL test for the training and validation sets were 0.205 and 0.414, respectively, indicating that the model was well-calibrated. Finally, the DCA curve indicated that the model had good clinical utility. CONCLUSION A simple nomogram based on three independent factors-duration of diabetes, BUN, and hemoglobin levels-may help clinicians predict the risk of developing PAD in patients with T2DM.

Abstract
Chronic limb-threatening ischemia (CLTI) represents the end stage of peripheral artery disease, a problem of growing prevalence and increased health care costs around the globe. CLTI is a highly morbid disease, incurring significant mortality, limb loss, pain, and diminished health-related quality of life. The major cause of non-traumatic lower extremity amputation are related to diabetes and CLTI. Between 2% to 3% of patients with peripheral artery disease present with a severe case of CLTI, a condition that is correlated with multilevel and multivessel arterial disease, calcification, and chronic total occlusions. Multiple technical strategies to successfully cross long occlusions in arterial segments have been described. Recanalization can be performed using endoluminal, subintimal, and retrograde techniques. We report a case of complex multilevel and multivessel endovascular revascularization through an occluded femoro-popliteal bypass in a patient with CLTI.

Abstract
PURPOSE Peripheral vascular disease (PVD) is a life-threatening condition affecting the lower extremities. Common risk factors include type 2 diabetes (T2D), hypertension, dyslipidemia, smoking, and older age. There is a little-documented research on the genetic basis of the disease in Taiwan. We examined the impact of T2D and the blood pressure-associated rs17367504 variant of the Methylenetetrahydrofolate reductase (MTHFR) gene on PVD risk. MATERIALS AND METHODS In this population-based association study, we linked data from 8992 participants in Taiwan Biobank (TWB) to their medical records in the National Health Insurance Research Database (NHIRD). Participants were 30 to 70 years old at recruitment and included those assessed between 2008 and 2015. We tested for association of PVD with rs17367504 and T2D using multiple logistic regression models. The rs17367504 variant was assessed using the Axiom-Taiwan Biobank Array Plate (TWB chip: Affymetrix, Inc., Santa Clara, CA, USA). RESULTS Among cases with T2D (n = 1294), 158 (12.21%) were identified with PVD. T2D was associated with PVD (odds ratio [OR], 1.52; 95% confidence interval [CI], 1.21-1.91; p<0.001) whereas rs17367504 variant was not (OR, 0.96; CI, 0.76-1.21; p = 0.728 in AG/GG compared to AA homozygotes). However, T2D and rs17367504 had an interactive effect on PVD (p for interaction = 0.0076). Results from our stratified analyses displayed OR of 1.75 (CI, 1.35-2.26; p<0.001) in AA individuals with DM and 0.94 (CI, 0.56-1.58; p = 0.811) in AG+GG individuals with T2D. Using the AA genotype and no T2D as the reference group, the respective OR of PVD was 1.77 (CI, 1.38-2.28; p<0.001) in AA individuals with T2D; 1.18 (CI, 0.91-1.55; p = 0.215) in AG+GG individuals with no T2D, and 1.03 (CI, 0.66-1.60; p = 0.892) in AG+GG individuals with T2D . CONCLUSION We found that type 2 diabetes was associated with increased risk of peripheral vascular disease, particularly in AA genotype carriers of the rs17367504 variant in Taiwan.

Abstract
BACKGROUND Diabetes-related lower extremity amputations (LEAs) are a major public health issue. The aim of the study was to evaluate trends by gender and predictors of LEAs in an Italian region. METHODS Data were collected from hospital discharge records between 2006 and 2015. Gender- and age-adjusted standardised hospitalisation rates for major and minor amputations were calculated. Poisson regression model was performed to estimate trends in LEAs. RESULTS Hospitalisation rates decreased for minor amputations both among males (-30.0%) and females (-5.3%), while the major amputation rates decreased only for males (-44.7%). Males were at higher risk of undergoing major (IRR 1.41, 95%CI 1.19-1.67) and minor (IRR 1.62, 95%CI 1.45-1.82) amputations. Peripheral vascular disease was the leading predictor of major and minor amputations. CONCLUSION A significant reduction of LEAs was observed only for males. Identifying their predictable factors may help caregivers to provide higher standards of diabetes care.

Abstract
Abstract Introduction: The high rate of diabetes mellitus index (DM), along with the increase in cardiovascular compromise that DM favors, and the scarcity of epidemiological data regarding the prevalence of peripheral arterial disease (PAD) in this population, make it important to study risk factors associated with the development of PAD in the population with type 2 diabetes mellitus (DM2). Objective: To estimate the prevalence of PAD together with the associated factors in a sample of patients with DM2, treated in the Family Health Strategies (FHS) program, in the municipality of Pindamonhangaba, SP. Methods: Quantitative research in a cross-sectional study of 38 individuals who were diagnosed with DM2, between 40 and 77 years old, selected by convenience sampling and treated in the family health program in two different districts of the municipality. The method consisted of the evaluation of personal and anthropometric data, anamnesis and physical examination including the ankle-brachial index (ABI). Results: PAD was present in 21.1% (95%CI: 16.9 to 25.8) of the investigated population. Risk factors observed were age range of 51 to 69 years (75%), overweight (50%), systemic arterial hypertension (SAH) (100%), smoking (62.5%) and physical inactivity (87.5%). Conclusion: The prevalence of PAD was more than a fifth of those diagnosed with DM2, and the most prevalent associated risk factors were SAH, physical inactivity, smoking and overweight with and without PAD.

Abstract
This systematic review examined the interrelationship between concomitant diabetes mellitus (DM) and peripheral arterial disease (PAD). The objective was to determine differences in the prevalence as well as in the outcomes in diabetic vs. non-diabetic PAD patients. The current review followed a study protocol that was published online in German in 2017. The search included societal practice guidelines, consensus statements, systematic reviews, meta-analyses, and observational studies published from 2007 to 2020 reporting symptomatic PAD and concomitant DM in patients undergoing invasive open-surgical and endovascular revascularizations. German and English literature has been considered. Eligibility criteria were verified by three independent reviewers. Disagreement was resolved by discussion involving a fourth reviewer. 580 articles were identified. After exclusion of non-eligible studies, 61 papers from 30 countries remained, respectively 850,072 patients. The included studies showed that PAD prevalence differed between diabetic vs. non-diabetic populations (20-50% vs. 10-26%), and further by age, gender, ethnicity, duration of existing diabetes, and geographic region. The included studies revealed worse outcomes regarding perioperative complications, amputation rate, and mortality rate in diabetic patients when compared to non-diabetic patients. In both groups, the amputation rates decreased during the research period. This review emphasizes an interrelationship between PAD and DM. To improve the outcomes, early detection of PAD in diabetic patients, and vice versa, should be recommended. The results of this systematic review may help to update societal practice guidelines.

Abstract
Arterial investigations are an essential part of lower extremity wound assessment. The results of these investigations assist the wound clinician to determine the etiology of the wound, predict healing capacity, and inform further management. There are a number of noninvasive testing methods available to practitioners, all with varying levels of reliability and accuracy. Clinical wound assessment guidelines give varied recommendations when it comes to lower limb vascular assessment in the presence of a wound. This leaves clinicians with little guidance on how to choose the most appropriate test, and uncertainty remains about which tests provide the most accurate information in different patient-specific contexts. Conditions such as advanced age, diabetes, and renal disease are known to affect the accuracy of some commonly used lower limb arterial assessment methods, and alternate testing methods should be considered in these cases. This seminal review discusses the reliability and accuracy of lower limb vascular assessment methods used to guide lower limb arterial assessment in the presence of wounds.

Abstract
Peripheral arterial disease (PAD) confers an elevated risk of major amputation and delayed wound healing in diabetic patients with foot ulcers. The major international vascular societies recently developed evidence-based guidelines for the assessment and management of patients with chronic limb-threatening ischaemia (CLTI). CLTI represents the cohort of diabetic and non-diabetic patients who have PAD which is of sufficient severity to delay wound healing and increase amputation risk. Diabetic patients with CLTI are more likely to present with tissue loss, infection and have less favourable anatomy for revascularization than those without diabetes. Although diabetes is not consistently reported as a strong independent risk factor for limb loss, major morbidity and mortality in CLTI patients, it is impossible in clinical practice to isolate diabetes from comorbidities, such as end-stage renal disease and coronary artery disease which occur more commonly in diabetic patients. Treatment of CLTI in the diabetic patient is complex and should involve a multi-disciplinary team to optimize outcomes. Clinicians should use an integrated approach to management based on patient risk assessment, an assessment of the severity of the foot pathology and a structured anatomical assessment of arterial disease as suggested by the Global Vascular Guidelines for CLTI.

Abstract
Osteopontin (OPN) is involved in the atherosclerotic and inflammatory process. In this article, we examined the relationship between circulating OPN levels with lower extremity arterial disease (LEAD) in individuals with type 2 diabetes mellitus (T2DM). Seventy individuals with T2DM and 66 individuals without T2DM were recruited. Diagnosis of LEAD was based on the absence of triphasic waveform on the pedal arteries. Plasma OPN levels were determined by Luminex Multiplex immunoassay. LEAD was present in 34 (48.6%) patients with T2DM. In the diabetes cohort, individuals with LEAD had higher plasma OPN concentrations than those without LEAD (geometric mean [95% confidence intervals]; 43.4 [37.5-50.4] vs 26.1 [22.9-29.8] ng/mL, respectively, P < .001). Multivariable analysis showed that presence of LEAD independently associated with higher OPN levels in subjects with T2DM, with marginal statistical significance ( P = .049). In both cohorts, plasma OPN concentrations were negatively associated with ankle-brachial index values ( P < .05). In the total sample, there was a gradual increase of OPN levels across subgroups with triphasic, biphasic, and monophasic/blunted waveforms ( P < .001). In conclusion, plasma OPN levels are associated with the presence and severity of LEAD in subjects with T2DM. Further studies are needed to investigate the role of OPN in the pathogenesis and progression of LEAD.

[PMID: 31839898 PMCID: PMC6896489 DOI: 10.1080/2000625x.2019.1696012] [Citation(s) in RCA: 16] [Impact Index Per Article: 3.2] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/11/2019] [Accepted: 11/13/2019] [Indexed: 12/21/2022]
Abstract
Objective: To describe the characteristics, the management and the outcome of a consecutive series of patients with diabetic foot lesions (DF) and no-option critical limb ischemia (CLI) treated with a multidimensional, interdisciplinary approach in a dedicated center. Research Design and Methods: The prospective database of the Diabetic Foot Unit of the Maria Cecilia Hospital (Cotignola, Italy) collects medical history, risk factors, chemistry values, angiographic data, characteristic of foot lesions, medical and surgical therapies of all patients admitted with a diagnosis of DF and CLI. All patients were followed-up for at least 1 year and/or total recovery. The primary endpoint was 1-year amputation-free survival (AFS), secondary endpoints were limb salvage and survival. Results: Between October 2014 and October 2017, 1024 patients with DF and CLI were admitted to the center. Eighty-four of them (8.2%) fulfilled the criteria for no-option CLI. At 1 year, AFS, limb salvage, and survival rates were 34%, 34%, and 83%, respectively. Lesions located proximal to the Lisfranc joint were associated with major amputation (HR 2.1 [1.2-3.6]). One-year survival of patients treated with minor procedures was significantly higher compared to patients treated with major amputation (96% vs 76%, log-rank p = 0.019). Major amputation was independently associated with mortality (HR 7.83 [1.02-59.89]). Conclusions: The application of dedicated and standardized strategies permitted limb salvage in one-third of patients with no-option CLI. Patients with stable lesions limited to the forefoot and without ischaemic pain had a greater probability to successfully receive conservative treatments. Limb salvage was associated with subsequent higher one-year survival.

Diabetes and risk of peripheral artery disease in patients undergoing first-time coronary angiography between 2000 and 2012 - a nationwide study. BMC Cardiovasc Disord 2019; 19:234. [PMID: 31651241 PMCID: PMC6813965 DOI: 10.1186/s12872-019-1213-1] [Citation(s) in RCA: 15] [Impact Index Per Article: 3.0] [Reference Citation Analysis] [Abstract] [Key Words] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/26/2019] [Accepted: 09/30/2019] [Indexed: 12/20/2022] Open
Abstract
Background The risk of peripheral artery disease (PAD) in patients with diabetes mellitus (DM) and coronary artery disease (CAD) is an important and inadequately addressed issue. Our aim is to examine the impact of DM on risk of PAD in patients with different degrees of CAD characterized by coronary angiography (CAG). Methods Using nationwide registers we identified all patients aged ≥18 years, undergoing first time CAG between 2000 and 2012. Patients were categorized into DM/Non-DM group, and further classified into categories according to the degree of CAD i.e., no-vessel disease, single-vessel disease, double-vessel disease, triple-vessel disease, and diffuse disease. Risk of PAD was estimated by 5-year cumulative-incidence and adjusted multivariable Cox-regression models. Results We identified 116,491 patients undergoing first-time CAG. Among these, a total of 23.969 (20.58%) had DM. Cumulative-incidence of PAD among DM patients vs. non-DM were 8.8% vs. 4.9% for no-vessel disease, 8.2% vs. 4.8% for single-vessel disease, 10.2% vs. 6.0% for double-vessel disease, 13.0% vs. 8.4% for triple-vessel disease, and 6.8% vs. 6.1% for diffuse disease, respectively. For all patients with DM, the cox-regression analysis yielded significantly higher hazards of PAD compared with non-DM patients with HR 1.70 (no-vessel disease), 1.96 (single-vessel disease), 2.35 (double-vessel disease), 2.87 (triple-vessel disease), and 1.46 (diffuse disease), respectively (interaction-p 0.042). Conclusion DM appears to be associated with increased risk of PAD in patients with and without established CAD, with increasing risk in more extensive CAD. This observation indicates awareness on PAD risk in patients with DM, especially among patients with advanced CAD.

Abstract
OBJECTIVE This study was undertaken to characterize structural and pharmacological properties of the pig popliteal artery in order to develop a novel system for the examination of lower limb blood flow regulation in a variety of cardiovascular pathologies, such as diabetes-induced peripheral artery disease. METHODS Popliteal arteries were isolated from streptozocin-induced diabetic pigs or age-matched saline-injected control pigs for morphological study using transmission electron microscopy and for examination of vasoreactivity to pharmacological agents using wire myography. RESULTS Transmission electron microscopy of the porcine popliteal artery wall revealed the presence of endothelial cell-smooth muscle cell interactions (myoendothelial junctions) and smooth muscle cell-smooth muscle cell interactions, for which we have coined the term "myo-myo junctions." These myo-myo junctions were shown to feature plaques indicative of connexin expression. Further, the pig popliteal artery was highly responsive to a variety of vasoconstrictors including norepinephrine, phenylephrine, and U46619, and vasodilators including acetylcholine, adenosine 5'-[β-thio] diphosphate, and bradykinin. Finally, 2 weeks after streptozocin-induced diabetes, the normalized vasoconstriction of the pig popliteal artery to norepinephrine was unaltered compared to control. CONCLUSIONS The pig popliteal artery displays structural and pharmacological properties that might prove useful in future studies of diabetes-associated peripheral artery disease and other lower limb cardiovascular diseases.

Abstract
This review considers peripheral arterial disease (PAD) in the diabetic ischaemic lower limb including both macrovascular and microvascular aspects. The presentation of PAD is probably not significantly different in type 1 compared with type 2 diabetes. PAD in diabetic patients is diffuse and located distally being most severe in the crural and also the foot arteries. It is associated with arterial calcification and occlusion of the arteries rather than stenosis. Compared with the nondiabetic patient, PAD develops at a younger age, and women are equally affected as men. It is not known whether the presentation of ischaemic lower limb disease in diabetes can be explained by one disease, namely, atherosclerosis, which has particular features peculiar to diabetes such as distal arterial involvement, or by the occurrence of two separate diseases: first, classical atherosclerosis and, second, a diabetic macroangiopathy, a term for nonatherosclerotic arterial disease in diabetes that is characterized by medial arterial calcification. Furthermore, there is controversy with regard to the significance of structural changes in the microcirculation of the diabetic foot.

Abstract
OBJECTIVE Taxane containing chemotherapy extends survival for breast cancer patients. However, taxane-induced peripheral neuropathy (TIPN) cannot be predicted, prevented or effectively treated. Using genome-wide analyses, we sought to identify common risk variants for TIPN. PATIENTS AND METHODS Women with high-risk breast cancer enrolled in SWOG 0221 were genotyped using the Illumina 1M chip. Genome-wide analyses were performed in relation to ≥grade 3 Common Terminology Criteria for Adverse Events (CTCAE) neuropathy in European and African Americans. Data were meta-analyzed with GW associations of CTCAE ≥grade 3 versus <grade 3 in CALGB 40101 assuming a fixed effects model. RESULTS The percentage of ≥grade 3 TIPN in 1269 European Americans and 139 African Americans in S0221, was 11.6 and 22.3%, respectively. CALGB 40101 ≥grade 3 TOPN was 7.2%. The most significant association with ≥grade 3 TIPN was the G allele of rs1858826 in GNGT1 (Pmeta=1.1×10), which showed a decrease in risk of ≥grade 3 TIPN (odds ratio=0.29, 95% confidence interval: 0.18-0.46). CONCLUSION The genetic variants associated with ≥grade 3 TIPN are hypothesized to have biochemical functions and reside in and near genes involved in diabetes and diabetic neuropathy. This finding is consistent with results from CALGB 40101 pathway analyses. Larger homogeneous trials with similar dosing and criteria for defining neuropathy are needed to properly assess the relationship of genomics with the neuropathy spectrum.

Abstract
BACKGROUND We sought to determine the prevalence of lower-extremity arterial calcification in a cohort of patients with diabetes and associated foot pathology receiving inpatient treatment at an urban US tertiary health-care system. METHODS The primary outcome measure was defined as either radiographic evidence of vessel calcification or noninvasive vascular testing that resulted in any reporting of vessel noncompressibility or an ankle-brachial index greater than 1.1. Radiographic evidence of vessel calcification was defined as radiodense calcification in the proximal first intermetatarsal space (deep plantar perforating artery), anterior ankle (anterior tibial artery), or posterior ankle (posterior tibial artery) on dorsoplantar and lateral foot projections. RESULTS Of the 367 individuals included in the study, 359 underwent radiography, with radiographic evidence of calcification in 192 (53.5%). Noninvasive vascular testing was performed on 265 participants, with any reporting of noncompressibility or an ankle-brachial index greater than 1.1 observed in 153 (57.7%). Ninety-four participants (25.6%) demonstrated evidence of arterial calcification on the radiographs and noninvasive testing, meaning that 251 participants (68.4%) demonstrated evidence of arterial calcification on at least one test, including 63.6% of participants classified as black/African American race, 65.4% as white race, and 78.3% as Hispanic/Latino ethnicity. CONCLUSIONS The results of this investigation increase the body of knowledge with respect to the evaluation and treatment of diabetic foot disease and may lead to future investigations on the topic of lower-extremity arterial calcification.

Abstract
Peripheral arterial disease (PAD) increases the risk of lower extremity amputation. It is also an independent predictor of cardiovascular and cerebrovascular ischemic events, affecting both the quality and expectancy of life. Many studies have demonstrated that the prevalence of PAD in patients with diabetes mellitus (DM) is higher than in non-diabetic patients. In diabetic patients, PAD occurs early with rapid progression, and is frequently asymptomatic. Multiple metabolic aberrations in DM, such as advanced glycation end-products, low-density lipoprotein cholesterol, and abnormal oxidative stress, have been shown to worsen PAD. However, the role of DM in PAD is not completely understood. The purpose of the present article is to review and discuss the pathophysiology of PAD in DM.

Abstract
Leg ulceration is a chronic health condition that constitutes a significant disease burden. In this cross-sectional descriptive study, a sample of wound care clinicians were asked to respond to a web-based survey. Based on a review of literature and recommended best practices in the management of mixed arteriovenous (AV) ulcers, a questionnaire was developed to examine the knowledge, attitude, and practice pattern in the management of AV ulcers. A total of 436 clinicians participated in the survey. A number of assessment techniques were perceived to be relevant for the assessment of AV ulcers; medical history and the appearance of ulcers were the most commonly used methods in clinical practice. While over 80% of the participants conceded that compression should be used to promote wound healing, half of them would consider using compression for AV ulcers if ankle brachial index was less than 0.8. Half of the participants considered an ankle brachial index of 0.8 or higher as the optimal cutoff value for safe compression. The majority of respondents disagreed with the perception that caring for people with AV ulcers was unrewarding. However, challenges to promote treatment adherence, address psychosocial concerns, and optimize symptom management are common.

Abstract
OBJECTIVES Peripheral arterial disease (PAD) represents a major and highly prevalent complication in patients with diabetes mellitus. The diagnostic, non-invasive work-up by computed tomography angiography (CTA) is limited in the presence of extensive calcification. The aim of the study was to determine the diagnostic accuracy of dual energy CTA (DE-CTA) for the detection and characterization of PAD in patients with diabetes mellitus. MATERIAL AND METHODS In this study 30 diabetic patients with suspected or known PAD were retrospectively included in the analysis. All subjects underwent DE-CTA (Somatom Definition Flash, Siemens Healthcare, Erlangen, Germany) prior to invasive angiography, which served as the reference standard. Blinded analysis included assessment of the presence and degree of peripheral stenosis on curved multiplanar reformatting (MPR) and maximum intensity projections (MIP). Conventional measures of diagnostic accuracy were derived. RESULTS Among the 30 subjects included in the analysis (83% male, mean age 70.0 ± 10.5 years, 83% diabetes type 2), the prevalence of critical stenosis in 331 evaluated vessel segments was high (30%). Dual energy CT identified critical stenoses with a high sensitivity and good specificity using curved MPR (100% and 93.1%, respectively) and MIP images (99% and 91.8%, respectively). In stratified analysis, the diagnostic accuracy was higher for stenosis pertaining to the pelvic and thigh vessels as compared with the lower extremities (curved MPR accuracy 97.1% vs. 99.2 vs. 90.9%; respectively, p < 0.001). CONCLUSION The use of DE-CTA allows reliable detection and characterization of peripheral arterial stenosis in patients with diabetes mellitus with higher accuracy in vessels in the pelvic and thigh regions compared with the vessels in the lower legs.

Abstract
BACKGROUND This study was designed to compare the findings of noninvasive arterial testing in patients with and without diabetic foot pathology. METHODS The ABI (ankle brachial index), TBI (toe brachial index), and great toe pressures were measured in 207 patients. PAD (peripheral artery disease) was defined as an ABI < 0.91 on either extremity or a TBI < 0.7. RESULTS PAD was identified in 103 of the 207 patients (49.8%), 80 patients with diabetic foot pathology and 23 patients with nondiabetic foot pathology. Although patients with diabetic foot pathology were 1.4 times more likely to have PAD compared to patients without diabetic pathology, this increased risk was not statistically significant (OR 1.41 [95% CI 0.75-2.64], P = .28). Patients with PAD and diabetic foot pathology were 4.9 times more likely to have ischemia (toe pressure < 60 mm Hg) than patients with PAD and nondiabetic foot pathology (OR 4.93 [95% CI 1.35-17.94], P < .05). Patients on dialysis had a 7.3 times increased likelihood of having PAD compared to patients not on dialysis (OR 7.3 [95% CI 1.6-33.6], P < .01). Patients with absent pedal pulses were 4.9 more likely to have PAD than patients with normal pulses (OR 4.9 [95% CI 2.6-9.4], P < .0001). PAD was identified in 97 of 188 patients (51.6%) with peripheral neuropathy compared to 6 of 19 patients (31.5%) without peripheral neuropathy (OR 2.31 [95% CI 0.84-6.33], P = .10). CONCLUSIONS Combining the ABI with TBI improved the ability to diagnose PAD in diabetic patients because the ABI has high specificity (low false positives) and the TBI has high sensitivity (low false negatives). The TBI was more reliable in patients with noncompressible arteries, medial artery calcinosis and/or neuropathy. Due to the relative incompressibility of calcified distal arteries in patients with DM, the ABI may be within normal limits in patients with PAD. This false negative result may lead surgeons to assume that normal perfusion is present.

Abstract
Diabetic foot ulcers are the main cause of non-traumatic lower extremity amputation. The objective of this study was to evaluate the risk factors for major amputation in diabetic foot patients. Eight hundred and sixty diabetic patients were admitted to the diabetic wound centre of the Korea University Guro Hospital for foot ulcers between January 2010 and December 2013. Among them, 837 patients were successfully monitored until complete healing. Ulcers in 809 patients (96·7%) healed without major amputation and those in 28 patients (3·3%) healed with major amputation. Data of 88 potential risk factors including demographics, ulcer condition, vascularity, bioburden, neurology and serology were collected from patients in the two groups and compared. Among the 88 potential risk factors, statistically significant differences between the two groups were observed in 26 risk factors. In the univariate analysis, which was carried out for these 26 risk factors, statistically significant differences were observed in 22 risk factors. In a stepwise multiple logistic analysis, six of the 22 risk factors remained statistically significant. Multivariate-adjusted odds ratios were 11·673 for ulcers penetrating into the bone, 8·683 for dialysis, 6·740 for gastrointestinal (GI) disorders, 6·158 for hind foot ulcers, 0·641 for haemoglobin levels and 1·007 for fasting blood sugar levels. The risk factors for major amputation in diabetic foot patients were bony invasions, dialysis, GI disorders, hind foot locations, low levels of haemoglobin and elevated fasting blood sugar levels.

Abstract
OBJECTIVES The toe-brachial index (TBI) is an alternative to the ankle-brachial index (ABI) in screening for peripheral arterial disease (PAD); however, there is limited evidence comparing their diagnostic accuracy. This study compared the diagnostic accuracy of the ABI and TBI in a population at risk of PAD. METHODS The sensitivity and specificity of the ABI and TBI were determined by color duplex sonography. Receiver operating characteristic (ROC) analysis was performed. RESULTS A total of 119 participants were recruited (75 male and 44 female). The sensitivity for PAD was highest for the TBI (71%; ABI, 45%), and the specificity was highest for the ABI (93%; TBI, 78%). Receiver operating characteristic analysis indicated that the TBI (ROC area, 0.77; P = .0001) had greater clinical efficacy for diagnosis of PAD than the ABI (ROC area, 0.65; P = .005). CONCLUSIONS In specific populations, the TBI may have greater clinical efficacy than the ABI for diagnosis of PAD.

Abstract
Medical imaging technologies are acquiring an increasing relevance to assist clinicians in diagnosis and to guide management and therapeutic treatment of patients, thanks to their non invasive and high resolution properties. Computed tomography, magnetic resonance imaging, and ultrasonography are the most used imaging modalities to provide detailed morphological reconstructions of tissues and organs. In addition, the use of contrast dyes or radionuclide-labeled tracers permits to get functional and quantitative information about tissue physiology and metabolism in normal and disease state. In recent years, the development of multimodal and hydrid imaging techniques is coming to be the new frontier of medical imaging for the possibility to overcome limitations of single modalities and to obtain physiological and pathophysiological measurements within an accurate anatomical framework. Moreover, the employment of molecular probes, such as ligands or antibodies, allows a selective in vivo targeting of biomolecules involved in specific cellular processes, so expanding the potentialities of imaging techniques for clinical and research applications. This review is aimed to give a survey of characteristics of main diagnostic non-invasive imaging techniques. Current clinical appliances and future perspectives of imaging in the diagnostic and prognostic assessment of diabetic complications affecting different organ systems will be particularly addressed.

Abstract
Evidence implicates a role of advanced glycation end products (AGEs) in the development of atherosclerosis. The present study examined the relationship between plasma levels of AGEs and the clinical and angiographic characteristics of patients with symptomatic peripheral arterial disease (PAD). A total of 40 consecutive patients with symptomatic lower extremity PAD undergoing invasive evaluation were enrolled. Clinical history, angiographic data, and plasma levels of total AGE (tAGE), N'-carboxymethyllysine (CML), and high-sensitivity C-reactive protein were obtained. In multivariate analyses, there were independent relationships noted between tAGE levels and the presence of critical limb ischemia (CLI) (r (2) = 0.195, p = 0.003), Rutherford stage (r (2) = 0.351, p < 0.001), and the average below the knee (BTK) score (r (2) = 0.119, p = 0.006). Presence of CLI (r (2) = 0.154, p = 0.012) and the Rutherford stage (r (2) = 0.194, p = 0.003) were associated with CML levels. We demonstrate a relationship between tAGE and the symptom profile of patients with PAD and an association between tAGE and infrapopliteal angiographic disease severity. Both tAGE and CML levels were related to the presence of CLI. These data suggest that AGE levels may reflect the severity of PAD and may be of importance in CLI.

Abstract
INTRODUCTION The effectiveness of hyperbaric oxygen therapy (HBOT) on selected diabetic foot wounds continues to be controversial. A holistic approach to diabetes and its comorbidities may be beneficial in the discussion of the proper application of this treatment modality. The aim of the current study is to evaluate the efficacy of HBOT on diabetic foot wounds and provide clinical data that may support this knowledge. METHODS The present study was a retrospective analysis of the effect of HBOT on diabetic foot lesions ranging 3-5 on the Wagner Grading System. Patients had been treated with HBOT and monitored for 12 months. The results were analyzed in relation to age, gender, diabetes duration and type, microangiopathic complications, peripheral arterial disease (PAD), history of coronary artery disease, stroke, hypertension, smoking habits, glycated hemoglobin, blood sedimentation rate, C-reactive protein, and number of HBOT sessions. Microangiopathies were evaluated as retinopathy, nephropathy, and neuropathy. PAD was determined by available color Doppler ultrasonography and/or angiographic data depending on a modified scoring system. The data of arteries from the aorta to the dorsal pedal artery were scored singly. Average scores of aorto-iliac, femoral, popliteal and pedal levels were also evaluated with this system to compare the healing results in relation to PAD. RESULTS One hundred and seventeen patients with 126 diabetic foot wounds were treated. Histories of coronary artery disease, stroke, and non-proliferative or proliferative retinopathy had negative effects on HBOT (P = 0.002, P = 0.015, P = 0.022, respectively). Depending on the scorings of PAD, the single arterial scores and average scores of aorto-iliac, popliteal and pedal levels had no relation to outcomes, while the average scores of the femoral arterial level affected the results (P = 0.048). CONCLUSIONS Diabetic foot patients with histories of coronary artery diseases or stroke and non-proliferative or proliferative retinopathy might resist HBOT. PAD at the femoral arterial level has been shown to have a significant negative effect on HBOT outcomes that should be first considered for surgery. In contrast, PAD below the knee does not seem to be an obstacle to the efficacy of HBOT.

Abstract
miRNAs are highly conserved non-coding RNA molecules that negatively control gene expression by binding to target mRNAs promoting their degradation. A multitude of miRNAs have been reported to be involved in angiogenesis and vascular remodelling. In the present review, we aim to describe the effect of miRNAs in post-ischaemic repair. First, we describe the miRNAs reported in ischaemic diseases and in angiogenesis. Then we examine their capacity to modulate the behaviour of stem and progenitor cells which could be utilized for vascular repair. And finally we discuss the potential of miRNAs as new clinical biomarkers and therapeutic targets.

Abstract
Ischemia and infection are the most important factors affecting the prognosis of foot ulcerations in diabetic patients. To improve the outcome of these patients, it is necessary to aggressively treat 2 important pathologies—namely, occlusive arterial disease affecting the tibial and femoral arteries and infection of the ischemic diabetic foot. Each of these 2 conditions may lead to major limb amputation, and the presence of both critical limb ischemia (CLI) and acute deep infection is a major risk factor for lower-extremity amputation. Thus, the management of diabetic foot ulcers requires specific therapeutic approaches that vary significantly depending on whether foot lesions are complicated by infection and/or ischemia. A multidisciplinary team approach is the key to successful treatment of a diabetic foot ulcer: ischemic diabetic foot ulcers complicated by acute deep infection pose serious treatment challenges because high levels of skill, organization, accuracy, and timing of intervention are required to maximize the chances of limb salvage: these complex issues are better managed by a multidisciplinary clinical group.

Abstract
We evaluated whether altered reporting of ischemic symptoms occurs in diabetic patients with peripheral arterial disease (PAD) and stable claudication. Patients (n = 152) with claudication were enrolled (120 males; mean age: 71.0 ± 8.6 years): 74 with diabetes (DM-PAD) and 78 without (DMfree-PAD). The degree of muscle oxygenation at symptom onset and maximal speed (Smax) during an incremental treadmill test was recorded at the gastrocnemius by near-infrared spectroscopy (NIRS) and quantified by area under the curve of oxygenated hemoglobin (AUC-Hbo2) and area under the curve of differential hemoglobin (AUC-dHb). The DM-PAD and DMfree-PAD showed similar exercise capacities inversely correlated with the degree of muscle oxygenation but significantly lower values of AUC-Hbo2 and AUC-dHb for DM-PAD at symptom onset and Smax (−356 vs −122 and −1200 vs −359, P < .0001). During a NIRS-assisted test, the report of claudication in the presence of diabetes was delayed, occurring at a lower degree of oxygenation than in patients with PAD only, with potential implications for testing, functional staging, and balance disorders.

Abstract
Diabetic foot (DF) is a chronic and highly disabling complication of diabetes. The prevalence of peripheral arterial disease (PAD) is high in diabetic patients and, associated or not with peripheral neuropathy (PN), can be found in 50% of cases of DF. It is worth pointing out that the number of major amputations in diabetic patients is still very high. Many PAD diabetic patients are not revascularised due to lack of technical expertise or, even worse, negative beliefs because of poor experience. This despite the progress obtained in the techniques of distal revascularisation that nowadays allow to reopen distal arteries of the leg and foot. Italy has one of the lowest prevalence rates of major amputations in Europe, and has a long tradition in the field of limb salvage by means of an aggressive approach in debridement, antibiotic therapy and distal revascularisation. Therefore, we believe it is appropriate to produce a consensus document concerning the treatment of PAD and limb salvage in diabetic patients, based on the Italian experience in this field, to share with the scientific community.

Abstract
INTRODUCTION Diabetes mellitus (DM) and intermittent claudication (IC) are frequently associated health conditions. Our hypothesis is that the nature, severity and quality of life (QoL) of patients with IC and DM are worse than those of claudicant patients without diabetes. MATERIAL AND METHODS An observational, cross-sectional and multicentre study of 920 patients with IC, divided into two groups: diabetic (n = 477) and non-diabetic (n = 443). For each group, we examined clinical and biological characteristics (including levels of glucose and lipids), the ankle-brachial index (ABI), responses to the Walking Impairment Questionnaire (WIQ) and the European Quality of Life-5 Dimensions (EQ-5D) questionnaire. RESULTS Compared with claudicant patients without diabetes, claudicants with diabetes were older (p < 0.001), more likely to be female (p = 0.006), with a higher BMI (p < 0.001), more likely to have a sedentary lifestyle (p < 0.001) and to be a non-smoker (p < 0.001). Claudicant patients with diabetes also had significantly more cardiovascular risk factors (p < 0.001), more frequent ischaemic cardiopathy (p = 0.023) and chronic renal failure (p = 0.002), and fewer prior ictus events (p = 0.003). No significant differences between groups were found with respect to blood pressure, levels of cholesterol or triglycerides. The mean ABI of diabetic-IC patients was slightly lower than IC patients without diabetes (p = 0.016). All WIQ subdomains scores were significantly lower (p < 0.001), indicating poorer walking ability, in claudicant and diabetic patients with compared with those without diabetes. The mean E5-QD global scores and the mean EQ-5D visual analogue scale in the whole series were 0.58 (SD = 0.21) and 55.04 (SD = 21.30), respectively. Both E5-QD scores were significantly lower, indicating poorer QoL, in claudicant patients with diabetes than claudicant patients without diabetes (p < 0.001). CONCLUSION Patients with IC and DM had more risk cardiovascular factors, cardiovascular conditions, disability and worse haemodynamic status and QoL than claudicant patients without diabetes.

Abstract
OBJECTIVE Peripheral arterial disease (PAD), as well as diabetic neuropathy, is a risk factor for the development of diabetic foot ulcers. The aim of this study was to evaluate differences and predictors of outcome parameters in patients with diabetic foot by stratifying these subjects according to the severity of PAD. RESEARCH DESIGN AND METHODS In a prospective study, patients with new diabetic foot ulcers have been treated and investigated by structured healthcare. Subjects were recruited between 1 January 2000 and 31 December 2007. All study participants underwent a 2-year follow-up observation period. The patients underwent a standardized examination and classification of their foot ulcers according to a modification of the University of Texas Wound Classification System. The severity of PAD was estimated by measurement of the ankle brachial index (ABI) and the continuous wave Doppler flow curve into undisturbed perfusion (0.9 < ABI < 1.3), compensated perfusion (0.5 < ABI < 0.9), decompensated perfusion (ABI < 0.5) and medial arterial calcification. RESULTS A total of 678 patients with diabetic foot were consecutively included into the study (69% male, mean age 66.3 ± 11.0 years, mean diabetes duration 15.8 ± 10.2 years). Major amputations (above the ankle) were performed in 4.7% of the patients. 22.1% of these subjects had decompensated PAD. These subjects had delayed ulcer healing, higher risk for major amputation [odds ratio (OR) 7.7, 95% confidence interval (CI) 2.8-21.2, p < 0.001] and mortality (OR 4.9, 95 % CI 1.1-22.1, p < 0.05). CONCLUSION This prospective study shows that the severity of PAD significantly influences the outcome of diabetic foot ulcers regarding to wound healing, major amputation and mortality.

Abstract
RATIONALE Circulating proangiogenic cells (PACs) support postischemic neovascularization. Cardiovascular disease and diabetes mellitus impair PAC regenerative capacities via molecular mechanisms that are not fully known. We hypothesize a role for microRNAs (miRs). Circulating miRs are currently investigated as potential diagnostic and prognostic biomarkers. OBJECTIVE The objectives were the following: (1) to profile miR expression in PACs from critical limb ischemia (CLI) patients; (2) to demonstrate that miR-15a and miR-16 regulate PAC functions; and (3) to characterize circulating miR-15a and miR-16 and to investigate their potential biomarker value. METHODS AND RESULTS Twenty-eight miRs potentially able to modulate angiogenesis were measured in PACs from CLI patients with and without diabetes mellitus and controls. miR-15a and miR-16 were further analyzed. CLI-PACs expressed higher level of mature miR-15a and miR-16 and of the primary transcript pri-miR-15a/16-1. miR-15a/16 overexpression impaired healthy PAC survival and migration. Conversely, miR-15a/16 inhibition improved CLI-PAC-defective migration. Vascular endothelial growth factor-A and AKT-3 were validated as direct targets of the 2 miRs, and their protein levels were reduced in miR-15a/16-overexpressing healthy PACs and in CLI-PACs. Transplantation of healthy PACs ex vivo-engineered with anti-miR-15a/16 improved postischemic blood flow recovery and muscular arteriole density in immunodeficient mice. miR-15a and miR-16 were present in human blood, including conjugated to argonaute-2 and in exosomes. Both miRs were increased in the serum of CLI patients and positively correlated with amputation after restenosis at 12 months postrevascularization of CLI type 2 diabetes mellitus patients. Serum miR-15a additionally correlated with restenosis at follow-up. CONCLUSIONS Ex vivo miR-15a/16 inhibition enhances PAC therapeutic potential, and circulating miR-15a and miR-16 deserves further investigation as a prognostic biomarker in CLI patients undergoing revascularization.

Abstract
OBJECTIVE The p75 neurotrophin receptor (p75(NTR)) contributes to diabetes mellitus-induced defective postischemic neovascularization. The interleukin-33 receptor ST2 is expressed as transmembrane (ST2L) and soluble (sST2) isoforms. Here, we studied the following: (1) the impact of p75(NTR) in the healing of ischemic and diabetic calf wounds; (2) the link between p75(NTR) and ST2; and (3) circulating sST2 levels in critical limb ischemia (CLI) patients. METHODS AND RESULTS Diabetes mellitus was induced in p75(NTR) knockout (p75KO) mice and wild-type (WT) littermates by streptozotocin. Diabetic and nondiabetic p75KO and WT mice received left limb ischemia induction and a full-thickness wound on the ipsilateral calf. Diabetes mellitus impaired wound closure and angiogenesis and increased ST2 expression in WT, but not in p75KO wounds. In cultured endothelial cells, p75(NTR) promoted ST2 (both isoforms) expression through p38(MAPK)/activating transcription factor 2 pathway activation. Next, sST2 was measured in the serum of patients with CLI undergoing either revascularization or limb amputation and in the 2 nondiabetic groups (with CLI or nonischemic individuals). Serum sST2 increased in diabetic patients with CLI and was directly associated with higher mortality at 1 year from revascularization. CONCLUSIONS p75(NTR) inhibits the healing of ischemic lower limb wounds in diabetes mellitus and promotes ST2 expression. Circulating sST2 predicts mortality in diabetic CLI patients.

Abstract
This review discusses the role of endovascular treatment in diabetic patients with critical limb ischemia (CLI). Angioplasty of the femoropopliteal region achieves similar technical success and limb salvage rates in diabetic and nondiabetic patients. Angioplasty in as many as possible tibial vessels is accompanied by more complete and faster ulcer healing as well as better limb salvage rates compared to isolated tibial angioplasty. Targeted revascularization of a specific vessel responsible for the perfusion of a specific ulcerated area is a promising new approach: it replaces revascularization of the angiographically easiest-to-access tibial vessel, even if this is not directly responsible for the perfusion of the ulcerated area, by revascularization of area-specific vascular territories. In conclusion, the endovascular approach shows very high efficacy in ulcer healing for diabetic patients with CLI. Larger prospective studies are now needed to estimate the long-term results of this approach.

Abstract
BACKGROUND Patients with diabetes often present with lower extremity (LE) edema; however, because of concomitant peripheral arterial disease, compression therapy is generally avoided by providers in fear of compromising arterial circulation. This pilot study sought to assess whether diabetic socks with mild compression (18-25 mm Hg) can reduce LE edema in patients with diabetes without negatively impacting vascularity. METHODS Eighteen subjects (9 males, 9 females) aged 61 ± 11 years with diabetes, LE edema, and a mean ankle-brachial index (ABI) of 1.10 ± 0.21 successfully completed this uncontrolled study. At baseline, subjects were fitted and instructed to wear the socks during all waking hours. Follow-up visits occurred weekly for four consecutive weeks. Edema was quantified through midfoot, ankle, and calf circumferences and cutaneous fluid measurements. Vascular status was tracked via ABI. RESULTS Repeated measures analysis of variance and least significant difference post hoc analyses were used for data analyses. Calf circumferences showed a statistically significant (p < .05) decrease of 1.3 ± 0.28 cm after just one week and remained significantly smaller than baseline throughout the study. Foot circumferences were significantly reduced at week 2 (-0.98 ± 0.35 cm) and remained significantly below baseline for the remainder of the study. The ankle also demonstrated a trend of circumference reduction but was not statistically significant. Cutaneous edema significantly reduced by week 3 (-3.1 ± 1.3 U) and remained so at week 4. Ankle-brachial index significantly increased (0.14 ± 0.049) at week 2 but was not significantly higher at weeks 3 or 4. No adverse events occurred during the study. CONCLUSIONS Mild compression therapy (18-25 mm Hg) decreased swelling in diabetes patients with LE edema without compromising vascularity.
